Vaccine is a substance introduced into the body to prevent infection or to control disease due to a certain pathogen. What is the need to have vaccines for sexually transmitted diseases (STDs)? The high health and economic costs of associated complications and the risk for carcinomas are some of the reasons why vaccines can be used in STDs. Besides the transmission of HIV is also increased in the presence of STDs. Vaccination is the most cost effective approach in the long term interventions to decrease STDs. Despite the fact that a number of vaccines have been developed, a still lot more are under various phase of trial. There are multiple hindrances at all levels of STD vaccine development. The problems associated with STD vaccines are that there can be change in the sexual behavior of the person. Parental acceptance is also necessary when vaccinating the minor. There are a number of STD vaccine candidates for development. STD vaccines can be live attenuated or killed. They can be used prophylactically or for therapeutic purposes. HBV is the STD vaccine first licensed for use. It is indicated for immunization against infection caused by all known subtypes of hepatitis B virus. It is given i.m on a 0, 1, 6 month schedule. It comes as EngerixB, Recombivax HB and Twinrix (HAV and HBV) in the market. It is recommended for all unvaccinated adolescents, all unvaccinated adults at risk for H BV infection and all adults seeking protection from HBV infection. Hepatitis A vaccine is FDA approved for persons aged> 12 months. It is given i.m as 2 doses (0, 6-12 months). It is available as Havrix and Vaqta. It is indicated for all MSM, Illegal drug users (both injecting and non injecting) and persons with chronic liver disease, including those with chronic Hepatitis B and Hepatitis C infection.

FDA licensed the first vaccine to prevent cervical carcinoma and other diseases caused by HPV. It is available as Gardasil and Cervarix. Gadasil is quadrivalent (HPV 6,11,16,18) and Cervarix is bivalent( 16,18). Gardasil is indicated in girls and women 9 through 26 years of age for


the prevention of the following diseases caused by Human Papillomavirus (HPV) types included in the vaccine:

Cervical, vulvar, vaginal, and anal cancer caused by HPVtypes 16 and 18

Genital warts (condyloma acuminata) caused

by HPV types 6 and 11

Cervical intraepithelial neoplasia (ClN) Vulvar intraepithelial neoplasia (VIN) Vaginal intraepithelial neoplasia (VaiN) Anal intraepithelial neoplasia (AIN)

It is also indicated in boys and men 9 through 26 years of age for the prevention of the following diseases caused by H PV types included in the vaccine:

Anal cancer caused by H PV types 16 and 18 Genital warts (condyloma acuminata) caused by HPV types 6 and I I Anal intraepithelial neoplasia (AIN)

There are numerous studies for therapeutic and prophylactic vaccines for HSV. They are yet to be adequately studied and efficacy tested. The greatest challenge while developing vaccine is that of HIV. There are multiple vaccines in different stages of trial. Is developing an HIV-1 vaccine possible? The success of the RV144 Thai HIV-1 efficacy trials with a replication-. defective recombinant canarypox vector (AlVAC)/gp 120 prime, clade B/E recombinant gp 120 protein boost showing 31 % efficacy has given hope that indeed a protective HIV-1 vaccine can be made.

The development of STD vaccine is not a substitute for protective sexual behaviour as it does not protect from all STDs. One should maintain confidentiality and give an informed choice to the patient while giving these vaccines.

Pimples http://iadvlmanipur.org/pimples/ http://iadvlmanipur.org/pimples/#respond Sat, 13 Apr 2024 05:20:28 +0000 https://iadvlmanipur.org/?p=1962

acne, pores, skin-1606765.jpgPimple (acne) is so common that it is considered to be a normal physiological reaction unless and until it develops into a boil. Over 80% of teenagers and 1 in 5 newborns have pimples of various forms with varying degrees of severity. Severe pimples can leave behind a trail of blemishes and in some labile persons can affect the self-image. A ‘simple pimple’ therefore can be ignored only at one’s peril.
Diet and dirt as believed by some to be the cause of pimples is not simply true. The skin oil wells (sebaceous glands) start producing lubricating oil (sebum lipid) from teenage years onward. These oil wells are plenty, about 700/cm2 in the face and upper body. It keeps the skin soft and supple and also inhibits some skin germs. When oil glands are overactive as happens in some people, the excess oil (seborrhoea) blocks the pores and ducts of the skin. Moreover, the pore lining cells become sticky in the presence of oil, and they get stuck up further plugging the pores. Thus, the oil products start to swell up in the form of white head (closed comedone) and black head (open comedone).
Another cause of pimples is the skin germ, Propionibacterium acnes which can transform oil into oil acid (free fatty acid). This acid damages the wall of pores allowing it to escape into surrounding deeper tissue causing untold damage in its wake. The resultant painful soft swelling pimple (cystic acne) often ends up in a pit, scar and blemish.
Some cosmetic agents notably old cream, soap and drugs give rise to pimple-like eruptions (acneiforms). Fat, grease, lubricating machine oil, tar, pomade and hair oil also can aggravate pimples by irritating and preventing the escape of sweat and body fluid onto the surface. This type is usually seen in individuals with oily skin.
The oil gland is also vulnerable to the effects of heat and humidity, a life-stress situation, lack of sleep, tension and a sumptuous lifestyle. For this reason, we see pimples flaring up during examination, menstruation, public festivity and upheaval.
Last but not least, it has been found that 50% of the pimple cases gave history of first-degree relative pimple affection. This family propensity is usually observed in severe types of pimples.
The approach to pimple management has to be multi-pronged. Great care a to be taken in choosing the type of medication as its effect on pimples can be damning. One approach is to explain and educate the person about his condition. This will give confidence, motivation and rapport to both the care receiver and provider. General measures as under will benefit the person. Rinse the face morning and evening with water using mild soap and dab the face gently after each rinse to retain moisture. Do not scrub your face as it removes the oil that the skin needs to be healthy and supple. Do not pick pimples. This may damage the skin and leave scars. Avoid facials since they sometimes aggravate the pimple. Carry out moderate exercise every day. Sleep 6-7 hours per day as lack of sleep may open up sleeping pimples. Avoid in-between meals and heavy snacks. Avoid hair oil and pomade. Use shampoo regularly. Drinking not less than 2 litres of water will help open up pores to clear pimples.
It is to be stressed that self-medication and manipulative measures will do more harm than good. Indeed, the affected person overestimates the severity of his pimple, while the physician underestimates its impact on the client.

Medical profession under legal aspects http://iadvlmanipur.org/medical-profession-under-legal-aspects/ http://iadvlmanipur.org/medical-profession-under-legal-aspects/#respond Sat, 13 Apr 2024 05:12:46 +0000 https://iadvlmanipur.org/?p=1956

gavel, justice, judge-7538565.jpgLegal aspects of medical practices have always constituted an important component in the growing civilization of our society. This necessity arose because of the existing laws of the land which provide for action in cases of medical negligence under the Indian Penal Code, Laws of Tort and Consumer Protection Act, 1986 etc. In the recent judgement of the Apex Court reported in (2005) 6 SCC 1, the Supreme Court discussed various legal aspects in the medical professions :-

MEDICAL NEGLIGENCE:
The subject of negligence in the context of Medical Profession necessary calls for treatment with a difference, There is a marked tendency to look for a human actor to blame for untoward event, a tendency which is closely linked with the desire to punish. Things have gone wrong and, therefore, somebody must be found to answer for it. An empirical study would reveal that the background to a mishap is frequently far more complex than may generally’ be assumed. It can be demonstrated that actual blame for the outcome has to be attributed with great caution. For a medical accident or failure, the responsibility may lie with the medical practitioner, and equally it may not. The inadequacies of the system, the specific circumstances of the case, the nature of human psychology itself and sheer chance may have combined to produce a result in which the doctor’s contribution is either relatively or completely blameless.
The human body and its working is nothing less than a highly complex machine. Compounded with the complexities of medical science, the scope for misimpression, misgivings and misplaced allegations against the operator i.e. the doctor, cannot be ruled out. One may have notions of best or ideal practice which are different from the reality of how medical practice is carried on or how the doctor functions in real life. The factors of pressing need and limited resources cannot be ruled out from consideration. Dealing with a case of medical negligence needs a deeper understanding of the practical side of medicine. The purpose of holding a professional liable for his act or omission, if negligent, is to make life safer and to eliminate the possibility of recurrence of negligence in future. The human body and medical science, both are two complex to be easily understood. To hold in favour of existence of negligence, associated with the action or inaction of a medical professional, requires an in-depth understanding of the working of professional as also the nature of the job and of errors committed by chance, which do not necessarily involve the element of culpability.
Negligence in the context of medical professional necessarily calls for a treatment with a difference. To infer rashness or negligence on the part of professional, in a particular doctor, additional considerations apply. A case of occupational negligence is different from one of the professional negligence. A simple lack of care, an error of judgement or an accident, is not proof of negligence on the part of medical professional.
So long as a doctor follows a practice acceptable to the medical profession of that day, he cannot be held liable for negligence merely because a better alternative course or method of treatment was also available or Simply because a more skilled doctor fellow would not have chosen to follow. It has been widelyaccepted as decisive of the standard of care required both of professional men generally and medical practitioners in particular, and holds good in its applicability in India. In tort, it is enough for the defendant to show that the standard of care and the skill attained was that of the ordinary competent medical practitioner exercising an ordinary degree of professional skill. The fact that a defendant charged with negligence acted in accord with the general and approved practice is enough to clear him of the charge. It is not necessary for every professional to possess the highest level of expertise in that branch which he practices. Three things are pertinent to be noted. Firstly, the standard of care, when assessing the practice as adopted, is judged in the light of knowledge available at the time (of the incident), and not at the date of trial. Secondly, when the charge of negligence arises out of failure to use some particular equipment, the charge would fail if the equipment was not generally available at that point of time (that is, the time of the incident) on which it is suggested as should have been used. Thirdly, when it comes to the failure of taking precautions, what has to be seen is whether those precautions were taken which the ordinary experience of men has found to be sufficient; a failure to use special or extraordinary precautions which might have prevented the particular happening cannot be the standard for judging the alleged negligence.
A person who holds himself out ready to give medical advice and treatment impliedly undertakes that he is possessed of skill and knowledge for that purpose. Such a person when consulted by a patient owes him certain duties viz. a duty of care in deciding whether to undertake the case, a duty to care in deciding what treatment to be given or a duty of care in the administration of that treatment. A breach of any of those duties gives a right of action for negligence to the patient. The practitioner must bring to his task a reasonable degree of skill and knowledge and must exercise a reasonable degree of care. Neither the very highest nor a very low degree of care and competence, judged in the light of the particular circumstances of each case, is what the law requires. The doctor no doubt has a discretion in choosing the treatment which he proposes to give to the patient and such discretion is relatively ampler in cases of an emergency.
Let it also be noted that a mere accident is not evidence of negligence. “”Accident”” during the course of medical or surgical treatment has a wider meaning. Care has to be taken to see that the result of an accident which is exculpatory may not persuade the human mind to confuse it with the consequence of negligence. So also an error of judgement on the part of a professional is not negligence. An error of
judgement may, or may not, be negligent; it depends on the nature of the error. If it is one that would not have been made by a reasonably competent professional man professing to have the standard and type of skill that the defendant held himself out as having, and acting with ordinary care, then it is negligent. If, on the other hand, it is an error that a man, acting with ordinary care, might have made, then it is not negligence. Higher the acuteness in emergency and higher the complication, more are the chances of error of judgement, At times, the professional is confronted with making a choice between the devil and the deep sea and he has to choose the lesser evil. The medical professional is often called upon to adopt a procedure which involves higher element of risk, but which he honestly believes as providing greater chances of success for the patient rather than a procedure involving lesser risk but higher chances of failure. Which course is more appropriate to follow, would depend on the facts and circumstances of a given case. The usual practice prevalent nowadays is to obtain the consent of the patient or of the person in-charge of the patient if the patient is not in a position to give consent before adopting a given procedure. So long as it can be found that the procedure which was in fact adopted was one which was acceptable to medical science as on that date, the medical practitioner cannot be held negligent merely because he chose to follow one procedure and not another and the result was a failure.
The jurisprudential concept of negligence defies any precise definition.
In current forensic speech, negligence has three meanings. They are : (i) a state of mind, in which it is opposed to intention; (ii) careless conduct; and (iii) the breach of a duty to take care that is imposed by either common or statute law. All three meanings are applicable in different circumstances but anyone of them does not necessarily exclude the other meanings.
Negligence is the breach of a duty caused by omission to do something which a reasonable man guided by those considerations which ordinarily regulate the conduct of human affairs would do, or doing something which a prudent and reasonable man would not do. Negligence becomes actionable on account of injury resulting from the act or omission amounting to negligence attributable to the person sued. The essential components of negligence, as recognized, are three: “”duty””, “”breach”” and “”resulting damage””, that is to say:
(1) the existence of a duty to take care, which is owed by the defendant to the complainant;
 (2) the failure to attain that standard of care, prescribed by the law, thereby committing a breach of such duty; and
(3) damage, which is both causally connected with such breach and recognized by the law, has been suffered by the complainant. If the claimant satisfies the court on the evidence that these three ingredients are made out, the defendant should be held liable in negligence.

NEGLIGENCE AS A TORT:
The jurisprudential concept of negligence defies any precise definition.
Eminent jurists and leading judgments have assigned various meanings to negligence. The concept as has been acceptable to Indian jurisprudential thought is well stated in the Law of Torts, Ratanlal & Dhirajlal (24th Edn., 2002, edited by Justice G.P. Singh). It is stated;
“”Negligence is the breach of a duty caused by the omission to do something which a reasonable man, guided by those considerations which ordinarily regulate the conduct of human affairs would do, or doing something which a prudent and reasonable man would not do. Actionable negligence consists in the neglect of the use of ordinary care or skill towards a person to whom the defendant owes the duty of
observing ordinary care and skill, by which neglect the plaintiff has suffered injury to his person or property …. the definition involves three constituents of negligence: (1) A legal duty to exercise due care on the part of the party complained of towards the party complaining the former’s conduct within the scope of the duty; (2) breach of the said duty; and (3) consequential damages. Cause of action for negligence arises only when damages occurs; for, damage is a necessary ingredient of this tort.””
According to Charlesworth & Percy on Negligence in current forensic speech, negligence has three meanings. They are (i) a state of mind, in which it is opposed to intention; (ii) careless conduct; and (iii) the breach of a duty to take care that is imposed by either common or statute law. All three meanings are applicable in different circumstances but anyone of them does not necessarily exclude the other meanings. The essential components of negligence, as recognized, are three : “”duty””, “”breach”” and”” resulting damage””, that is to say:
(1) the existence of a duty to take care, which is owed by the defendant to the complainant;
(2) the failure to attain that standard of care, prescribed by the law, thereby committing a breach of such duty; and
(3) damage, which is both causally connected with such breach and recognized by the law, has been suffered by the complainant. If the claimant satisfies the court on the evidence that these three ingredients are made out, the defendant should be held liable in negligence.
NEGLIGENCE – AS A TORT AND AS A CRIME:
The term “”negligence”” is used for the purpose of fastening the defendant with liability under the civil law and, at times, under the criminal law. It is contended on behalf of the respondents that in both the jurisdictions, negligence is negligence, and jurisprudentially no distinction can be drawn between negligence under civil law and negligence under criminal law. The submission so made cannot be countenanced inasmuch as it is based upon a total departure from the established terrain of though running ever since the beginning of the emergence of the concept of negligence up to the modem times. Generally speaking, it is the amount of damages incurred which is determinative of the extent of liability in tort; but in criminal law it is not the amount of damages but the amount and degree of negligence that is determinative of liability. To fasten liability in criminal law, the degree of negligence has to be higher than that of negligence enough to fasten liability for damages in civil law. The essential ingredient of means rea cannot be excluded from consideration when the charge in a criminal court consists of criminal negligence. Lord Diplock spoke in a Bench of five and the other Law Lords agreed with him He reiterated his opinion and dealt with the concept of recklessness as constituting in criminal law. His Lordship warned against adopting the simplistic approach of treating all problems of criminal liability as soluble by classifying the test of liability as being “”subjective”” or “”objective””, and said:
In order to hold the existence of criminal rashness or criminal negligence it shall have to be found out that the rashness was of such a degree as to amount to taking a hazard knowing that the hazard was of such a degree that injury was most likely imminent. The element of criminality is introduced by the accused having run the risk of doing such an act with recklessness and indifference to the consequences. Lord Atkin in his speech in Andrews v. Director of Public Prosecutions sated : “”Simple lack of care such as will constitute civil liability is not enough. For purposes of the criminal law there are degrees of negligence, and a very high degree of negligence is required to be proved before the felony is established.””
Thus, a clear distinction exists between”” simple lack of care”” incurring civil liability and II very high degree of negligence”” which is required in criminal cases. In Riddell V. Reid Lord Porter said in his speech-
“”A higher degree of negligence has always been demanded in order to establish a criminal offence than is sufficient to create civil liability.””
The fore-quoted statement of law in Andrews has been noted with approval by Supreme Court in Syad Akbar V. State of Karnataka. The Supreme Court has dealt with and pointed out with reasons the distinction between negligence in civil law and in criminal law. Their Lordships have opined that there is a marked difference as to the effect of evidence viz. the proof, in civil and criminal proceedings. In civil proceedings, a mere preponderance of probability is sufficient, and the defendant is not necessarily entitled to the benefit of every reasonable doubt; but in criminal proceedings, the persuasion of guilt must amount to such a moral certainty as convinces the mind of the Court, as a reasonable man, beyond all reasonable doubt. Where negligence is an essential ingredient of the offence, the negligence to be
established by the prosecution must be culpable or gross and not the negligence merely based upon an error of judgment.
Law laid down by Straight, J. in the case of Empress of India V. Idu Beg has been held good in cases and noticed in Bhalchandra Waman Pathe V. State of Maharashtra a three-Judge Bench decision of Supreme Court. It has been held that while negligence is an omission to do something which a reasonable man, guided upon those considerations which ordinarily regulate the conduct of human affairs, would do, or
doing something which a prudent and reasonable man would not do; criminal negligence is the gross and culpable neglect or failure to exercise that reasonable and proper care and precaution to guard against injury either to the public generally or to an individual in particular, which having regard to all the circumstances out of which the charge has arisen, it was the imperative duty of the accused person to have adopted.
The factor of grossness or degree does assume significance while drawing distinction in negligence actionable in tort and negligence punishable as a crime. To be latter, the negligence has to be gross or of a very high degree.
MEDICAL PROFESSIONALS IN CRIMINAL LAW:
The criminal law has invariably placed medical professionals on a pedestal different from ordinary mortals. The Indian Penal Code enacted as far back as in the year 1860 sets out a few vocal examples. Section 88 in the Chapter on General Exceptions provides exemption for acts not intended to cause death, done by consent in good faith for person’s benefit of a person without his consent though the acts cause
harm to the person and that person has not consented to suffer such harm. There are four exceptions listed in the section which are not necessary in this context to deal with. Section 93 saves from criminality certain communications made in good faith. To these provisions are appended the following illustrations :
“” ‘A’, a surgeon, knowing that a particular operation is likely to cause the death of ‘Z’, who suffers under a painful complaint, but not intending to cause ‘Z’s’ death, and intending, in good faith, ‘Z’s’ benefit, performs that operation on ‘Z’, with ‘Z’s’ consent. A has committed no offence.””
“”(a) ‘Z’ is thrown from his horse, and is insensible. A, a surgeon, finds that ‘Z’ requires to be trepanned. ‘A’, not intending ‘Z’s’ death, but in good faith, for ‘Z’s’ benefit, performs the trepan before ‘Z’ recovers his power of judging for himself. ‘A’ has committed no offence.
(c) ‘A’, a surgeon, sees a child suffer an accident which is likely to prove fatal unless an operation be immediately performed. There is no time to apply to the child’s guardian. ‘A’ performs the operation in spite of the entreaties of the child, intending, in good faith, the child’s benefit. A has committed no offence.””
“” ‘A’, a surgeon, in good faith, communicates to a patient his opinion that he cannot live. The patient does in consequence of the shock. A has committed no offence, though he knew it to be likely that the communication might cause the patient’s death.””
“”To punish as a murderer every man who, while committing a heinous offence, causes death by pure misadventure, is a course which evidently adds . nothing to the security of human life. No man can so conduct himself as to make it absolutely certain that he shall not be so unfortunate as to cause the death of a fellow creature. The utmost that he can do is to abstain from every thing which is at all likely to cause death. No fear of punishment can make him do more than this; and therefore, to punish a man who has done this can add nothing to the security of human life. The only good effect which such punishment can produce will be to deter people from committing any of those offences which turn into murders what are in themselves mere accidents. It is in fact an addition to the punishment of those offences, and it is an addition made in the very worst way.””
“”When a person engaged in the commission of an offence causes death by rashness or negligence, but without either intending to cause death, or thinking it likely that he shall cause death, it is to be proposed that he shall be liable to the punishment of the offence which he was engaged in committing, superadded to the ordinary punishment of involuntary culpable homicide.
The arguments and illustrations which employed for the purpose of showing that the involuntary causing of death, without either rashness or negligence, ought, under no circumstances, to be punished at all, will, with some modifications, which will readily suggest themselves, serve to show that the involuntary causing of death by rashness or negligence, though always punishable, ought, under no circumstances to be punished as murder.””
The following statement of law on criminal negligence by reference to surgeons, doctors, etc. and unskillful treatment contained in Roscoe’s Law of Evidence (15th edn.) is classic :
“”Where a person, acting as a medical man & c., whether licensed or yardstick for judging the performance of the professional proceeded against on indictment of negligence.
(4) The test for determining medical negligence as laid down in holds good in its applicability in India.
(5) The jurisprudential concept of negligence differs in civil and criminal law. What may be negligence in civil law may not necessarily be negligence in criminal law. For negligence to amount to an offence, the element of means rea must be shown to exist. For an act to amount to criminal negligence, the degree of negligence should be much higher i.e. gross or of a very high degree. Negligence which is neither gross nor of a higher degree may provide a ground for action in civil law but cannot form the basis for prosecution.
(6) The word “”gross”” has not been used in Section 304-A I PC, yet it is settled that in criminal law negligence or recklessness, to be so held, must be of such a high degree as to be II gross””. The expression II rash or negligent act”” as occurring in Section 304-A IPC has to be read as qualified by the word II grossly””.
(7) To prosecute a medical professional for negligence under criminal law it must be shown that the accused did something or failed to do something which in the given facts and circumstances no medical professional in his ordinary senses and prudence would have done or failed to do. The hazard taken by the accused doctor should be of such a nature that the injury which resulted was most likely imminent.
(8) Res ipsa loquitur is only a rule of evidence and operates in the domain of civil law, specially in cases of torts and helps in determining the onus of proof in actions relating to negligence. It cannot be pressed in service for determining per se the liability for negligence within the domain of criminal law. Res ipsa loquitur has, if at all, a limited application in trial on a charge of criminal negligence.
GUIDELINES – RE : PROSECUTING MEDICAL PROFESSIONALS:
As noticed hereinabove that the cases of doctors (surgeons and physicians) being subjected to criminal prosecution are on an increase sometimes such prosecutions are filed by private complainants and sometimes by the police on an FIR being lodged and cognizance taken. The investigating officer and the private complainant cannot always be supposed to have knowledge of medical science so as to determine whether the act of the accused medical professional amounts to a rash or negligent act within the domain of criminal law under Section 304-A IPC. The criminal process once initiated subjects the medical professional to serious embarrassment and sometimes harassment. He has to seek bail to escape arrest, which mayor may not be granted to him. At the end he may be exonerated by acquittal or discharge but the loss which he has suffered to his reputation cannot be compensated by any standards.
We may not be understood as holding that doctors can never be prosecuted for an offence of which rashness or negligence is an essential ingredient. All that we are doing is to emphasise the need for care and caution in the interest of society; for, the service which the medical profession renders to human beings is probably the noblest of all, and hence there is a need for protecting doctors from frivolous or unjust prosecutions. Many a complainant prefer recourse to criminal process as a tool for pressurising the medical professional for extracting uncalled for or unjust compensation. Such malicious proceedings have to be guarded against.
Statutory rules or executive instructions incorporating certain guidelines need to be framed and issued by the Government of India and/ or the State Governments in consultation with the Medical Council of India. So long as it is not done, it is propose to lay down certain guidelines (or the future which should govern the prosecution of doctors for offences of which criminal rashness or criminal negligence is an ingredient. A private complaint may not be entertained unless the complainant has produced prima facie evidence before the court in the form of a credible opinion given by another competent doctor to support the charge of rashness or negligence on the part of the accused doctor. The investigating officer should, before proceeding against the doctor accused of rash or negligent act or omission, obtain an independent and competent medical opinion preferably from a doctor in government service, qualified in that branch of medical practice who can normally be expected to give an impartial and unbiased opinion applying the Bolam test to the facts collected in the investigation. A doctor accused of rashness or negligence, may not be arrested in a routine manner (simply because a charge has been levelled against him). Unless his arrest is necessary, for furthering the investigation or for collecting evidence or unless the investigating officer feels satisfied that the doctor proceeded against would not make himself available to face the prosecution unless arrested, the arrest may be withheld.

summer, sunshine, sun-297586.jpgUltraviolet radiation is that portion of the electromagnetic spectrum with a narrow band of radiation from 200-400 nm. Spectrum – UVC (200-290 nm), UVB (290- 320 nm) and UV A (320-400nm –UV A 2 =320-340; UVA 1 = 340-400). UVA rays constitute 90-95% of the ultraviolet light reaching the earth and it is not absorbed by the ozone layer. UV A light penetrates deep into the skin and is involved in sun tanning, UV A tends to suppress the immune function and is implicated in photoaging of the skin by inducing changes in the extracellular matrix decreased collagen synthesis, increased degradation of collagen, infiltration of inflammatory cells and release of ROS from neutrophils etc. UVB rays – partially absorbed by the ozone layer, are the primary cause of sunburn and reach upto papillary dermis only. It is also responsible for photoaging, photo carcinogenesis and are implicated in cataract formation. UVC rays are almost totally absorbed by the ozone layer. However with the depletion of the ozone layer because of environmental pollution UVC rays are beginning to contribute to sunburn and premature ageing of the skin.

Sunscreens- divided into chemical absorbers and physical blockers. Chemical sunscreens absorb high-energy ultraviolet rays and release the energy later as heat. No significant photo degradation occurs except avobenzones.

Physical blockers or non chemical sunscreens reflect or scatter UVR. They contain inert minerals such as titanium dioxide or zinc oxide. (new nanosized particles may help by absorption also)


1. Ultraviolet B Blockers –

Para-aminobenzoic acid- one of the first chemical sunscreens, padimate 0 or octyl dimethyl PABA is associated with greater compatibility, Padimate 0 is the most potent UV-B absorber.

Cinnamates- Octyl methoxy cinnamate ( OCTINOXATE) is the most frequently used sunscreen ingredient.

Octyl salicylate – Octisalate or octyl salicylate is used to augment the UV-B protection in a sunscreen.

Octocrylene – Octocrylene used in combination with other sunscreen ingredients, such as avobenzone, add to the overall stability.

Phenyl benzimidazole sulfonic acid – (Ensulizole) is water soluble ,used in products formulated to feel lighter and less oily.


2. Ultraviolet A Blockers – Benzophenone

Although benzophenones are primarily UV-B absorbers, oxybenzone absorbs well through UV-A2. Oxybenzone is considered a broad-spectrum absorber.

Anthranilate – absorb mainly in the UV-A2 portion, less widely used.

Avobenzone – (ParsoI1789) a large portion of the UV-A range, including UVAl

Mexoryl SX- ( L’oreal) – (ecamsule) photo stable, block UV -A range (320- to 340-nm); it is water soluble and less water resistant.

Helioplex (Neutrgena)- Oxybenzone + abobenzone stabilised with 2, 6, diethylexylnaphalate

Bisethylhexyloxyphenol methoxy phenyl triazene – This broadband sunscreen filter lends photostability to avobenzone containing sunscreens.


Physical blockers – inert minerals such as titanium dioxide or zinc oxide; particles scatter and reflect the solar radiation. Ultrafine titanium dioxide, provides broad-spectrum protection against UV, it is invisible when applied in cosmetic formulations. Chemically stable and do not cause photo-allergic or contact dermatitis and do not break down over time and are far less liable to cause skin irritation. However protection against UVA 1 is superior for zinc oxide (340- 380nm), more broad spectrum. (Good for porphyrias)

Sunscreen vehicles: Most effective UV absorbers are oils – heavy, greasy feel, polymeric film formers and silicone oils – less greasy; ‘ultrasheer’ products utilise silica; gels- rely on phenyl benzimidazole sulfonic acid or trolamine salicylate

Systemic photo protection – Systemic agents, eliminate substantivity , include PABA, indomethacin, retinol, steroids, psoralen, antimalarials and antioxidants like vitamin A, vitamin C, vitamin E and beta-carotene. Antioxidants are less potent than sunscreens in preventing sunburn.


Indications & Contraindications of Sunscreens –


Indications:

Protection from UVR to prevent the following-

– Sunburn

– Skin or lip damage, freckling, skin discoloration

– Skin aging

– Skin cancer

– Phototoxic or photo allergic drug reactions

– Photosensitivity diseases

– Photo aggravated dermatoses.


Contraindications

– Known sensitivity to any sunscreen ingredient or vehicle ingredient

– Infants < 6 months

– As sole component of an overall program of photoprotection


Side effects of sunscreens –

– Upto 19% of users can develop adverse reaction, to both active and vehicle ingredient equally.

– Majority are irritant in nature, < 10 % allergic, and most patch test negative.

– Subjective irritation- immediate stinging or burning , without visible erythema, most frequently in the eye area, even if applied away from, by migration through sweating; even several hrs after application, falsely implicated as allergy.

– contact urticaria

– allergic contact dermatitis – PABA earlier, benzophenones increasingly nowadays, fragrances, preservatives and other excipients

– photosensitivity reactions- sunscreen active ingredients have become the leading cause of photo contact allergic reactions, mainly to avobenzone. Photosensitive eczematous pts particularly predisposed (suspect in clinical exacerbation).

– acne induction and exacerbation vehicles may induce ; mainly aggravation of pre-existing acne; contact folliculitis (shortly after application) a form of irritation.


Effectiveness and efficacy of Sunscreens

1. UV B
a) Sun protection factor (SPF) – Amount of ultraviolet energy (UVB) required to produce minimal erythema on sunscreen protected skin-(2 mg/cm 2 layer) to the amount of energy required on unprotected skin.

b) Substantivity – the ability of a sunscreen to remain effective under the stress of prolonged exercise, sweating and swimming.

Sweat-resistant: protects up to 30 minutes of continuous heavy perspiration.

Water-resistant: protects up to 40 minutes of continuous water immersion and

Waterproof (very water resistant) : protects for up to 80 minutes of continuous water immersion

PABA and its esters demonstrate more resistance to sweating and/ or water immersion than do other chemical sunscreens.


2. UV A 

Protection of Sunscreen- no uniformly accepted standard method for measuring UV A protection of sunscreen. PPD (persistent pigment darkening) is most commonly used because pigmentation remains stable between 2 and 24 hours.

Broad-spectrum label should have a critical wavelength of more than 370 nm and a PPD or protection factor in UV A greater than 4.


Some more facts –

– Even on cloudy days up to 80% of UVR is transmitted to the Earth’s surface.

– Sun exposure during childhood (upto 18 yrs is about 80% of an average person’s lifetime exposure ton the sun)

– Sun protection should begin at young age and may start as early as 6 months of age

– Surfaces such as sand, snow, concrete and water can reflect up to 85% of the UV radiation

– UV A penetrate window glass, UVB do not; indoor light sources have been shown to emit UV A, UVB & sometimes UVC rays.(i.e. indoor exposure possible)

– UV A varies much less in intensity throughout the day than UVB.

Instruction to patients:

1. Depending on latitude and climate, sunscreens may be needed yearround.

2. Sunscreens most important from lOAM to 4 PM. To protect from harmful radiation during this period, stay in shade or indoors .

3. For intermittent casual daily use, an SPF 15 is sufficient. For prolonged recreational exposures, an SPF30 is desirable.

4. Sunscreens should be applied 15-30 minutes before exposure, reapply after activities such as swimming, sweating and rubbing. Common advice earlier was to apply sunscreen every 2-3 hours, (however new research shows that reapplication 15- 30 minutes after the sun exposure begins may be the best way)

5. Apply liberally. Most do not. An adequate amount of sunscreen (2 mg/ ern 2) provides greater sun protection than using an inadequate amount of a sunscreen with a higher SPF rating. The teaspoon rule: (~3ml) to each arm, to the face and the neck. On each leg, the chest and back, (~6ml); about 30 ml to cover entire body.

6. Patients should select broad-spectrum sunscreens that contain agents that effectively block both UVB and UV A preferably above SPF 30. The SPF applies for UVB rays and near UVB- i.e. UV A-2 only. A sunscreen with a SPF of 15 filters out approximately 94%, with a SPF of 30 filters out 97 % of UVB (difference in penetration of about 3 % not significant in most clinical situations).

Patients requiring UV A protection should apply sunscreens longer particularly with drug photosensitivity or various photoaggravated dermatoses.

Natural pigments such as titanium dioxide and zinc oxide are good UVB and UVA blockers. Today, certain chemicals can be added to sunscreen products to give them good UVA ray blocking abilities. Such chemicals include avobenzone and Mexoryl SX.

However, most of cosmetic products that contain sunscreen chemicals offer various SPF levels up to 15-30.

Future trends in photoprotection – in stages of investigation- The antioxidants are caffeic acid, poly podium leukotomes, zinc, polyphenolic compounds, isoflavone, N-acetylcysteine and butyrated hydroxy toluene (synthetic antioxidant). Calcitriol and citrus which are free radical scavengers. Plant oligosaccharides and genistein help in prevention of UV ind uced immunosuppression.


Sunscreens alone are insufficient for protection from UVR as they prevent sunburn from UV -B radiation and provide more limited protection from UV-A radiation. Protective clothing and sun avoidance particularly at times of peak intensity is warranted.

Facial Rejuvination http://iadvlmanipur.org/facial-rejuvination/ http://iadvlmanipur.org/facial-rejuvination/#respond Sat, 13 Apr 2024 04:54:42 +0000 https://iadvlmanipur.org/?p=1944

woman, portrait, female-8643502.jpgRejuvenation is the noun of the verb word ‘rejuvenate’ which means” make young or as if young again” as per the 9th edition of Concise Oxford Dictionary. It comes from Latin – “juvenis” – young.

The Process of rejuvenation is as old as history itself. Cleopatra used Ass’s milk to keep herself young & beautiful. Balms have been used since the time of the Pharaohs of Egypt. India was never far behind. It is said the sages lived for centuries.

We have lost the formulas with time, yet the undaunted search was always there.

The first person who rejuvenated himself was he who washed himself with water. Yes, water is a good rejuvenator, though it is very evanescent. In fact all modalities are transient, some less than the other.

We cannot stop ageing, we can only postpone it. The urge to look better and remain young as long as possible has initiated people to delve into the mysteries of the body and to search for that ” Amrit” or the “Elixir” of life, to defy death & ageing. The search is still on.

Now let us understand what is rejuvenation. It is an improvement of skin texture, closure of big pores, reduction of scars, marks & blemishes, reduction of facial hairs, lightening of the skin to look fairer, tightening and toning of the skin, reduction of blemishes & wrinkles, and reduction of excessive fat.

Recent advances in Cosmetic Dermatology have come up with many options which, though costly, give us a rather satisfactory result. The modalities can be surgical or non-surgical, ablative or non-ablative.

With Micro Dermabrasion we remove the dead cells and stimulate fresh growth of Epidermis. With aloe vera & other moisturizers we make the skin more turgid & it gives a polished look.

To decrease dark-pigmented lesions & tattoo marks we use Q-switched ND Yag Lasers.

To decrease vascular leacons we use IPL Lasers & Pulse Dye Lasers. To decrease hairs we can use IPL or High frequency Ruby Laser pulse

To remove Seborrhoic Keratosis or Acanthosis Nigricans can use Alexandrite Lasers.

To increase the collagen bulk and initiate fibroblast formation, which is the main anchor of rejuvenation we can use non-ablative low-energy photothermal treatment, Radiofrequency instrument, IPL Laser etc.

To remove pockmarks & depressed scars we can use radio frequency instruments, RF cutting of the margins of the scars, derma roller, dermal fillers, laser resurfacing etc & also with medicines.

To improve wrinkles, along with creams, we can use derma roller, dermal fillers, and laser resurfacing. :

We also use Botox to relax taut muscles & relax the muscular tension which also gives the face a youthful look.

With the increasing popularity of “Beauty Competitions” and the instinctive urge to look good and more confident, young as well as older people are seeking professional help. The emerging super speciality called “Cosmetic Dermatology” has come to stay. The domain of Dermatologists is touching newer horizons and expanding rapidly for the service of mankind.

Senescence and ageing skin http://iadvlmanipur.org/senescence-and-ageing-skin/ http://iadvlmanipur.org/senescence-and-ageing-skin/#respond Sat, 13 Apr 2024 04:46:40 +0000 https://iadvlmanipur.org/?p=1938

man, hands, wrinkled-8060589.jpgAfter a period of perfect renewal, in humans between 20-35 years of age, there is a gradual declining ability to respond to stress, increased homeostatic imbalance and increased risk of disease. This irreversible series of changes is inevitable for life. Death is the ultimate consequence. “Old age” is not scientifically recognized as a cause of death because there is always a specific proximal cause, such as cancer, heart disease or liver failure. This is what we call senescence.

Life is about such changes and skin is the proof of aging and is at the mercy of many forces as we age. Intrinsic ageing is due to various factors like genetics, apoptosis, wear and tear, free radicals, hormonal decline, accumulation of waste products etc. Many of the conditions cannot be intervened, though some may be modifiable. But could we expand the lifespan? Maybe or maybe not! But each species has its own prescribed life period too. With modified healthy lifestyle and measures, like modified food habits, carbohydrate restriction, exercise, stress reduction, good sleep, bio-identical hormone corrective measures, antioxidant supplements etc., quality of life can certainly be improved with a low probability of diseases and disability with high cognitive and physical functional capacity.

The ageing of the skin (external) is seen vividly. 80% of the cause is contributed by photodamage. Other important causes are smoking, stress, poor nutrition, environmental pollution etc. Dry skin, fine lines and wrinkles, freckles, skin tags, red spots, pigmentations, telangiectasia, atrophy, laxity, and premalignant cutaneous conditions are the signs of ageing skin. Many of these conditions can be prevented. Many are treatable or at least modifiable.

Management of ageing skin includes measures to prevent UV damage and medications and procedures to reverse existing damages. Sunscreens, topical retinoids, peptides, and vitamin C are used with good results. Systemic and topical antioxidants have variable results. Various rejuvenation procedures like chemical peels, botox, facial fillers, radio frequency, lasers and other light systems are giving excellent results. Perhaps these may be a booming medical industry.
