Chemical Damage

<p class="abstract"><span lang="EN-US">Hair straightening is a popular hair procedure. The first hair straightening products were used for African hair. Various modes of hair straightening methods are currently being used. Temporary methods like blow drying and ironing are used for easy manageability of hair, both by modern men and women. Salon- based hair straighteners were initially permanent relaxers which, with time, evolved to formaldehyde-free hair strengthening procedures like hair Botox which is currently in trend. It improves hair manageability, increases hair strength and reduces frizz without producing much chemical damage to hair and by maintaining their natural waves, thereby producing a more natural look. We performed a thorough literature search on the topic in PubMed, consulted various hair stylists and beauty school professors prior to formulation of this article. The article aims at understanding the basic mechanisms involved in various hair straightening methods which helps us to advice patients on a wholesome care of hair.</span></p>

Canal Of Nuck

The processus vaginalis is an envagination of parietal peritoneum which accompanies the round ligament through the inguinal ring into the inguinal canal. The portion of processus vaginalis within the inguinal canal in women is called ‘the canal of Nuck’. When the processus vaginalis fails to close, it can result in a hernia or hydrocele in both men and women. Female hydrocele of the canal of Nuck is uncommon. A literature search revealed that little has been published on this condition. We present a case of a hydrocele of the canal of Nuck in a 23-year old female who had an irreducible swelling over the left groin for three months and increasing in size on straining. The cyst was excised with round ligament and a repair of inguinal canal with closure of deep ring was done.

Comprehensive Literature Search

The purpose of this study was to understand the adverse consequences of driving reduction or cessation among elderly adults. A comprehensive literature search was conducted for studies that ( a) included information on driving by an elderly population, ( b) included results from a qualitative or quantitative (or both) study of the elderly and driving cessation, and ( c) provided information to evaluate consequences surrounding driving reduction or cessation. The selected subjects of the studies included men and women over the age of 55 years. Driving reduction or cessation is associated with a number of adverse consequences, including reduced activity out of the home and decreased life satisfaction. However, determining causality of the associations is difficult because of unidentified third variables (such as health). Understanding the adverse consequences will aid researchers and policy makers to develop better strategies to help people anticipate and prepare for reduced driving and to develop and improve transportation alternatives.

Objective: To review the common types and prevalence of sexually transmitted infections (STIs) among college students. Methods: Conducted a literature search in Google and PubMed, and 33 reports were analyzed on this subject. Results: The highest prevalence of STIs are among college aged students with approximately two thirds of students reporting having sex in the last year; men and women having 14 and 12 sex partners, respectively, on average in college. STIs range from common curable ones like chlamydia to deadly incurable ones like human immunodeficiency virus. Conclusion: Strategies to prevent STIs to help protect not only one’s health, but the health of others, are to limit the number of sex partners, wear a condom, get tested, and receive vaccinations that prevent STIs.

Prolactin producing pituitary adenomas are ultrastructurally characterized by secretory granules varying in size (150-300nm), abundance of endoplasmic reticulum, and misplaced exocytosis. They are also subclassified as sparsely or densely granulated according to the amount of granules present. The hormone levels in men and women vary, being higher in men; so also the symptoms vary between both sexes. In order to understand this variation, we studied 21 prolactin producing pituitary adenomas by transmission electron microscope. This was out of a total of 80 pituitary adenomas. There were 6 men and 15 women in this group of 21 prolactinomas.All of the pituitary adenomas were fixed in 2.5% glutaraldehyde, rinsed in Millonig's phosphate buffer, and post fixed with 1% osmium tetroxide. They were then en bloc stained with 0.5% uranyl acetate, rinsed with Walpole's non-phosphate buffer, dehydrated with graded series of ethanols and embedded with Epon 812 epoxy resin.

Two separate studies investigated race and sex differences in normal auditory sensitivity. Study I measured thresholds at 500, 1000, and 2000 cps of 23 white men, 26 white women, 21 negro men, and 24 negro women using the method of limits. In Study II thresholds of 10 white men, 10 white women, 10 negro men, and 10 negro women were measured at 1000 cps using four different stimulus conditions and the method of adjustment by means of Bekesy audiometry. Results indicated that the white men and women in Study I heard significantly better than their negro counterparts at 1000 and 2000 cps. There were no significant differences between the average thresholds measured at 1000 cps of the white and negro men in Study II. White women produced better auditory thresholds with three stimulus conditions and significantly more sensitive thresholds with the slow pulsed stimulus than did the negro women in Study II.
