For example acne 6 weeks pregnant order zoretanin with american express, a local immune reaction to insulin crystals with resultant dedifferentiation of adipocytes has been suggested [14 acne 8 days before period buy zoretanin in india,18] acne excoriee zoretanin 30 mg without a prescription. An immunemediated inflammatory process with release of lysosomal enzymes promoting lipoatrophy has also been proposed [19]. It has also been suggested that mast cells may play a pathogenetic role [12]: in one case series involving five patients with human insulin analogueinduced lipoatrophy, an elevated number of tryptasepositive, chymasepositive degranulated mast cells were seen in the subcutaneous tissue. Disease course and prognosis Semicircular lipoatrophy has an excellent prognosis as most cases resolve gradually upon withdrawal of repetitive trauma. However, lesions usually regress spontaneously after the removal of microtrauma over months to as long as 8 years [12]. Predisposing factors this form of lipoatrophy is more common among those with prior dermal reactions to insulin [1]. Pathology Histopathology shows lobules of small adipocytes and lipomembranous changes [21]. A discrete lymphoid infiltration abutting the blood vessels in the hypodermis may also be observed [22]. It was recognized at an early stage that they were capable of producing profound lipoatrophy if they were injected into subcutaneous fat. These reactions include pain, panniculitis, haemorrhage, secondary infection, pigment alteration, hypersensitivity and atrophy [2]. Of all the persistent local reactions due to corticosteroids, atrophy is the most common [3]. Interestingly, there is concomitant lipohypertrophy in approximately 25% of patients [23]. In one early study, it was observed that lipoatrophy occurred in six of 14 women but in none of 13 men who received repeated intramuscular or deep subcutaneous injections of triamcinolone diacetate [4]. It is believed that intramuscular injection of triamcinolone has a direct traumatic and a hormonally mediated destructive effect on fat cells [5]. In addition, decreased type I collagen and glycosaminoglycan synthesis has been noted following the injection of corticosteroid [6]. One common finding from histological analyses is the identification of a granular basophilic material in the dermis, thought to represent altered ground substance associated with deposits of corticosteroid crystals [5,7,8]. Cutaneous atrophy has been noted to resolve in parallel with the gradual disappearance of corticosteroid crystals from the tissue [7]. Complications and comorbidities Because insulin absorption from the lipoatrophic area is erratic, continued injection of insulin into affected areas may result in poor glycaemic control [22]. Once lipoatrophy develops, continued injection into the lipoatrophic site should be avoided due to erratic absorption of insulin. Spontaneous resolution of established insulininduced localized lipoatrophy is rare. There is no generally agreed management algorithm but, if feasible, a change to purified human insulin is recommended. Several authors describe success in restoring fat by coadministration of a corticosteroid such as dexamethasone with the insulin [4,18,24,25]. Other strategies have included using an insulin jetinjection device [26] or a continuous insulin infusion pump [27], although lipoatrophy with the latter has also been reported [7,8]. Twicedaily application of 4% sodium cromoglycate prepared in petrolatum has been claimed to reverse early lipoatrophy and prevent new lesions in one small case series [12].

Genetics There seems to be a genetic predisposition to the development of cellulite as most women with cellulite report its occurrence in other family members [12] skin care 30s buy generic zoretanin 30mg on line. Differential diagnosis Obesity is differentiated from cellulite in that obesity is characterized by hypertrophy and hyperplasia of adipose tissue that is not Obesity and the skin 100 acne quizlet discount 20 mg zoretanin visa. The ideal management for this condition acne hacks 40 mg zoretanin with mastercard, which so many women find distressing and for the treatment of which considerable sums have been expended, has yet to be found. Obesity exposes people not only to wellknown metabolic and cardiovascular consequences including type 2 diabetes but also has significant effects on other body systems including the skin [2]. Whilst this may be of benefit in protecting the body from the effects of exposure to cold it also means that it is harder for the obese to dissipate heat from the core out to the skin surface. This increases the reliance on sweating for thermoregulation in obese people, who tend to sweat more profusely than those who are not overweight [3]. Paradoxically, however, transepidermal water loss is increased in obese people, who are prone to xerosis [4]. Friction, sweating and maceration within body folds frequently lead to a painful erosive intertriginous dermatitis with secondary candidosis. Obese women with restricted mobility are more likely to have problems with urinary continence, which can contribute further to inflammation, with an irritant contact dermatitis affecting the genitocrural folds [5]. Stretch marks (striae distensae) are common, particularly if weight gain has been rapid [2,5,6]. They tend to be located in the axillary folds, upper thighs, buttocks and abdomen. The mechanical effects of obesity may impede lymphatic drainage not only in the lower extremities but also elsewhere, for example in abdominal apron folds, resulting in lymphoedema [3]. The chronic high pressure exerted on the skin of the soles of the feet may result in plantar hyperkeratosis and postmenopausal plantar keratoderma (keratoderma climactericum) [2,6]. Lower limb venous hypertension from whatever cause may be exacerbated in the obese by high intraabdominal pressures and by immobility. The risks of venous eczema and venous ulceration are increased and they may be more difficult to manage. The prevalence of superficial skin infections such as candidosis, dermatophytosis and erythrasma is raised in the obese [2]. Pyogenic infections such as folliculitis and furunculosis are also more frequently seen and may be recurrent. Obesity also increases the risk of surgical wound infection and of necrotizing fasciitis [8]. It is increasingly recognized that adipose tissue has multiple, complex regulatory and hormonal functions in addition to its role as an energy store (see Chapter 99); these functions may be disturbed in the obese. Altered adipocytokine secretion may have an effect on inflammation in the obese [9,10]: for instance, delayedtype hypersensitivity responses are increased in obesity and decline with weight reduction [11]. Adipocytokines may also play a role in the wellrecognized link between severe psoriasis and obesity, with evidence that weight reduction, including that achieved by bariatric surgery, can produce significant improvement in psoriasis [2,12,13]. There is also some evidence of a link between obesity and atopy including atopic eczema [2,13]. Case control study of semicircular lipoatrophy, a new occupational disease in office workers.

Tufting may be reduced by measures directed at reducing the scale, such as the use of tar shampoos and topical keratolytics. Other measures tried include oral dapsone, oral zinc, laser depilation and surgical excision [5]. Fracture of hair shafts, which can be extensive, may also be caused by overuse of chemical treatments such as permanent waves and relaxers. Tufted folliculitis is a variant of folliculitis decalvans where cir cumscribed areas of scalp inflammation heal with scarring char acterized by tufts of up to 30 hairs emerging from a single orifice (Figure 89. The tufts consist of a central anagen hair surrounded by telogen hairs, each arising from independent fol licles, converging towards a common dilated follicular infundibu lum. Cases in which the tufts were comprised of only anagen hairs have also been described. A scalp biopsy is required to confirm the diagnosis and swabs should be taken of any pustules. Investiga tion for an underlying defect in cellmediated immunity is gen erally unrewarding, and only indicated when there is additional Traction alopecia Traction alopecia is brought about by hairstyles that impose sus tained pulling on the hair roots. The clinical features in the many variants of this syndrome include folliculitis, hair casts [2], reduc tion in hair density with vellus hairs and sometimes broken hairs in the affected areas, and eventually scarring alopecia. The pattern of the hair loss is often distinctive and reflects the dis tribution of the traction (Figure 89. A population study from South Africa reported an incidence of trac tion alopecia in 17. It was more common in women with relaxed hair as well as traction hairstyles such as braiding [4,5]. Problems typically start in childhood, where they may initially be reversible [6]. A degree of temporal thinning may also be part of a genetic hair pattern seen in those with no traction. Pressure ischaemia can occur during intensive care or gynae cological surgery in the Trendelenburg position [14]. In one large clinic, over a period of 3 years, 60 cases of occipital pressure alo pecia were observed after openheart surgery [15]. Temporary alopecia followed prolonged pressure on the scalp by a foam rubber ring used to prevent such an occurrence [16]. Trichotillomania is a behavioural disorder characterized by com pulsive hair pulling. It presents as a pattern of hair loss, often bizarre, with no clear biological or overt traumatic explanation [1]. Compulsive hair rubbing (trichoteiromania [2]) and hair cutting (trichotemnomania [3]) fall into the same general category. The patient, or parents of affected children, need to be educated to adopt hair styles that do not pull the hair tight [9]. Where there is inflamma tion, mild steroids can be helpful, but are not a substitute for a nontraction hairstyle.
