Effective Ways To Remove Pubic Hair
Hair removal lasers all target melanin. Unwanted hairs tend to be relatively large and dark. There is a much higher concentration of melanin in the hair follicle than in the surrounding skin this difference provides selectivity so that the laser's effect is much greater on the hair follicle than elsewhere. Human hair varies widely in diameter and color as well as in growth characteristics the response to laser hair removal treatment is affected by all of these physical features. Because of the broad range of wavelengths that affect melanin (see chapter 4), several different lasers are effective for hair removal ruby (694 nm), alexandrite (755 nm), diode (810 nm), and Nd YAG (1064 nm) lasers. These lasers have variable power settings, spot sizes and pulse durations, all of which can affect the efficacy of treatment. The hair follicle is a relatively large structure, and significant amounts of energy are required to damage it a relatively long laser pulse is required to deliver the...
To ensure uniform contact of the metal bar with the skin, the hair is removed prior to creating the burns. Kaufman et al. (5) recommend removing the hair with clippers and a depilatory cream at least 24 h before inflicting burns, since clipping and depilation may produce skin edema. However, after experimenting with a variety of depilatory creams, hair removal waxes, and clippers, we have noted that hair removal with electric clippers immediately before the burns is most simple and does not have any appreciable histological effects on healing of the burns. By contrast, shaving the hair with a razor should be avoided, since shaving has been reported to significantly increase the rate of infection in comparison with clipping (15).
In the late 1990s, new lasers were developed for the purpose of removing unwanted hair. All of these lasers target the chromophore melanin, which in dark hair is present at greater concentrations in the hair follicle than in the surrounding skin. White or gray hair follicles cannot be treated as effectively because they lack melanin. Most of the lasers used for hair removal are similar to the Q-switched lasers (ruby, alexandrite, Nd YAG) but are run in normal mode with pulses of laser energy much longer than those generated by a Q-switch. The longer pulses are needed to impart sufficient energy to the hair follicle to cause its destruction. Many of these laser systems require simultaneous use of a skin coolant to protect the epidermis, with its lower melanin content, from excessive heating. Ironically, cutaneous lasers seem to have come full circle since the
Seen in 50-60 of adolescent boys and usually occurs during Tanner stages 2 or 3. It is usually painful and may be unilateral or bilateral. It gradually appears and gradually disappears within 1 year of onset. Pubertal changes that occur during Tanner stages 2 and 3 include growth spurt, growth of testes and penis, spermarche, acne, axillary perspiration, and appearance of pubic hair. The boy in this case should be reassured and followed monthly. If the gynecomastia does not resolve, it will be necessary to rule out Klinefelter syndrome, adrenal tumors, gonadal tumors, hyperthy-roidism, hepatic disorders, and the use of drugs, especially marijuana and bodybuilding steroids. Tanner 1 Young child penis, scrotum, and testes no pubic hair Tanner 2 Enlargement of scrotum and testes penis the same scrotal skin becomes more red, thinner, and wrinkled some straight pubic hair at base of penis Tanner 3 Enlargement of penis and testes scrotum descends dark, curly pubic hair Tanner 4 Further...
Patients with folliculitis present with painful red papules overlying a hair follicle (Fig. 10). Folliculitis can be exacerbated by friction, shaving, or other trauma to the pubic hair-bearing area. These lesions sometimes enlarge to form furuncles, which are painful, red nodules measuring 1 to 2 cm (Fig. 11). The center of the lesion is filled with purulent material that releases by rupture or surgical incision. Carbuncles represent coalescing furuncles. Constitutional symptoms of fevers, generalized malaise, and chills are uncommon unless significant cellulitis is present.
In girls, the onset of puberty is marked by breast budding and the development of pubic and axillary hair. Both breast and pubic hair development progress through characteristic stages, described by Tanner as Stages 1 through 5, with Stage I representing prepubertal characteristics and Stage 5, full maturity.1 The age at which pubertal changes begin and their rate of progression vary considerably among individuals, although on average in North America, the pubertal transition begins at age 10-11 years (range 8-13).2 Initiation of breast development usually occurs first, and is followed by initiation of pubic hair development, peak height velocity, and menarche, respectively. Menarche usually occurs at a Tanner Stage of 3-4 for breast development. The first menstrual bleedings, however, are not usually associated with ovulatory cycles, and the establishment of regular ovulatory cycles does not occur for several years. For example, only 15 of cycles are ovulatory in the first year after...
A 9-year-old girl has breast and pubic hair development. Evaluation demonstrates a pubertal response to a gonadotropin-releasing hormone (GnRH) stimulation test and a prominent increase in lutein-izing hormone (LH) pulses during sleep. These findings are characteristic of patients with
P. corporis may manifest as a macule or papule with a hemorrhagic punctate lesion on the shoulders, trunk, or buttocks. In P. capitis nits are attached to the hair shaft close to the scalp. Nits may also be seen in the pubic hair when infested with P. pubis.
Follow local standing operating procedure (SOP) and local advocacy policy. Have the child describe the attacker as completely as possible if the person is not a family member or a friend. You may have the child describe the nature of the attack. Use dolls and drawings as methods of gathering this information from the child. Objective evidence must be gathered such as samples from the vagina, pubic hair, etc. The examining physician will collect these samples from the patient. Be sure any other evidence at the scene is protected.
Trim dorsal skin hair with an electric clipper. Remove hair shafts using a commercially available hair depilatory. We use Nair applied in a thick layer evenly covering the hair stubble (see Note 8). 2. After 30 min, completely remove the depilatory agent from the skin by several washings and scrubbing with coarse gauze (see Notes 9 and 10). 4. While the depilatory is working, prepare the template block by heating to 70 C in a constant temperature water bath (this takes 20-30 min).
In females, estrogens are secreted by the developing ovarian follicle and by the corpus luteum (see Lesson 6, para 6-11b). During pregnancy, the placenta secretes estrogens. Estrogens are responsible for the development of the uterus, vagina, fallopian tubes, and breasts. Estrogen also produces such physiological effects as accelerating growth at puberty (causes epiphyses of long bones to close), increasing clotting factors in circulation, and decreasing bone reabsorption. Estrogen produces female secondary sex characteristics (like distribution of fat, development of pubic hair, high-pitch voice, and increased skin pigmentation). In males, there is limited estrogen secretion by the adrenal glands. (3) Anabolism increases the synthesis and decreases the breakdown of protein. Androgens also act to produce secondary sex characteristics associated with the male (like development of pubic hair and facial hair, development of a deeper pitched voice, and development of...
Overfolding upper helix, and small or absent earlobes. Hypoplastic teeth are common. Hand findings include short metacarpals and fingers, clinodactyly (60 ), simian crease (45 ), and characteristic prints. They exhibit a wide gap between the first and second toes. Cardiac abnormalities are present in 49 , with endocardial cushion defects, ventricular septal defects (VSDs), patent ductus arteriosus (PDA), and atrial septal defects (ASDs). Cutaneous manifestations include dry skin, cutis marmorata, fine, soft sparse hair, and straight pubic hair. Occasionally, patients have seizures, strabismus, and low-set ears. Patients are at higher risk for duodenal atresia, atlantoaxial instability, leukemia, and thyroid disease.
Effluents from slaughterhouses and packing houses are usually heavily loaded with solids, floatable matter (fat), blood, manure, and a variety of organic compounds originating from proteins. As already stated the composition of effluents depends very much on the type of production and facilities. The main sources of water contamination are from lairage, slaughtering, hide or hair removal, paunch handling, carcass washing, rendering, trimming, and cleanup operations. These contain a variety of readily biodegradable organic compounds, primarily fats and proteins, present in both particulate and dissolved forms. The wastewater has a high strength, in terms of biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), nitrogen and phosphorus, compared to domestic wastewaters. The actual concentration will depend on in-plant control of water use, byproducts recovery, waste separation source and plant management. In general, blood and intestinal contents arising...
Pubic lice, Phthirus pubis, are small, macroscopic parasites that are generally sexually transmitted, annoying, and medically trivial. Fomites also are known to transmit lice. Also called ''crabs,'' these organisms localize to the pubic hair and eyelashes, and these are distinct from head lice. Figure 24 (See color insert) Pubic lice are small parasites that cling to pubic hair, with nits appearing as teardrop-shaped eggs attached to hair shafts.

The elevated, fatty tissue covered with coarse pubic hair and which lies over the symphysis pubis is the mons pubis. Pubic hair appears at puberty. The function of the mons pubis is to protect the pelvic bone. (3) Labia minora. The labia minora is composed of two folds of skin lying within the labia majora and enclosing the vestibule. In front, each labium minus (minus is the singular form of minora) divides into two folds. The fold above the clitoris is called the prepuce of the clitoris. The fold below is the frenulum. No pubic hair is on these structures
A 16-year-old girl is brought into the gynecologist's office by her mother because she has not had her first menses. She states that all her daughter's friends in school have menstruated, and she is concerned about her daughter's lack of menstruation. The patient has no significant personal or family history, and on examination she seems to be well-nourished, with adult breast development and pubic hair present. A pelvic examination is not performed at the initial office visit. Are breasts present or absent A physical examination will evaluate secondary sexual characteristics (breast development, axillary and pubic hair, growth). Breasts are an endogenous assay of estrogen. Presence of breasts indicates adequate estrogen production. Absence of breasts indicates inadequate estrogen exposure.
Additional specimens, such as samples of the patient's pubic hair and fingernail scrapings, may be needed for evaluation. The presence of Trichomonas vaginalis and condyloma acuminatum after age 3 years is highly suggestive of sexual abuse. Meticulous documentation is required in sexual abuse evaluations.
A 16-year-old girl is brought to the physician by her modier because she has not yet begun to menstruate. She is concerned because all of her other friends got their periods years ago. She is not sexually active and denies excessive dieting or exercise. Physical examination reveals normal adult-type breasts, a sparse amount of axillary and pubic hair, and a blind-ending vagina. A sonogram reveals that the uterus and ovaries are absent. She has male levels of testosterone. Which of the following is the most likely cause of her condition

The first stages in meat processing occur in the slaughterhouse (abattoir) where a number of common operations take place, irrespective of the species. These include holding of animals for slaughter, stunning, killing, bleeding, hide or hair removal, evisceration, offal removal, carcass washing, trimming, and carcass dressing. Further secondary operations may also occur on the same premises and include cutting, deboning, grinding, and processing into consumer products.
Water is used in the slaughterhouse for carcass washing after hide removal from cattle, calves, and sheep and after hair removal from hogs. It is also used to clean the inside of the carcass after evisceration, and for cleaning and sanitizing equipment and facilities both during and after the killing operation. Associated facilities such as stockyards, animal pens, the steam plant, refrigeration equipment, compressed air, boiler rooms, and vacuum equipment will also produce some wastewater, as will sanitary and service facilities for staff employed on site these may include toilets, shower rooms, cafeteria kitchens, and laboratory facilities. The proportions of water used for each purpose can be variable, but as a useful guide the typical percentages of water used in a slaughterhouse killing hogs is shown in Figure 3.2 11 .
