Singapore has developed over the past 3 decades with improvement in housing, nutrition and general health. The pattern of skin diseases has changed from conditions like pyodermas and malnutrition to predominantly eczemas. The paediatric cases seen at Middle Road Hospital consist of 13% of general dermatology cases (509 of 37,964 total new cases in 1986). About 2.7% (138) of the children were below 1 year, 32.5% (1630) were below 1-4 years and 64.5% (3251) were below 14 years of age. The ten most common dermatoses (1986) follow a similar trend in most of the developed towns of Asia. This includes eczemas 32.0% (1603 cases); 14.5% (730) of atopics, non-specified eczemas 9.6% (481), hand eczema 4.1% (209), contact dermatitis 1.7% (90), discoid eczema 1.15% (57), seborrhoeic 0.7% (36). The remaining are viral warts 6.8% (342), scabies 3.2% (302), acne 3.7% (180), pyoderma 3.5% (175), dermatophytes 3.3% (169), urticaria 2.6% (134), pityriasis rosea 0.1% (51) and vitiligo 0.09% (46).

Data is reviewed on premenstrual symptoms which have been related to high suicide and accident rates, employment absentee rates, poor academic performance and acute psychiatric problems. A recent study of healthy young women indicated that 39% had troublesome premenstrual symptoms, 54% passed clots in their menses, 70% had cyclical localized acneiform eruptions and only 17% failed to experience menstrual pain. Common menstrual disorders are classified as either dysmenorrhea or the premenstrual syndrome. Symptoms for the latter usually begin 2-12 days prior to menstruation and include nervous tension, irritability, anxiety, depression, bloated breasts and abdomen, swollen fingers and legs, headaches, dizziness, occasional hypersomia, excessive thirst and appetite. Some women may display an increased susceptibility to migraine, vasomotor rhinitis, asthma, urticaria and epilepsy. Symptoms are usually relieved with the onset of menses. While a definitive etiological theory remains to be substantiated, symptomatic relief has been reported with salt and water restriction and simple diuretics used 7 to 10 days premenstrually. Diazapam or chlordiazepoxide treatment is recommended before oral contraceptive therapy. The premenstrual syndrome may persist after menopause, is unaffected by parity, and sufferers score highly on neuroticism tests. Primary or spasmodic dysmenorrhea occurs in young women, tends to decline with age and parity and has no correlation with premenstrual symptoms or neuroticism. Spasmodic or colicky pain begins and is most severe on the first day of menstruation and may continue for 2-3 days. Treatment of dysmenorrhea with psychotropic drugs or narcotics is discouraged due to the risk of dependence and abuse. Temporary relief for disabling pain may be obtained with oral contraceptives containing synthetic estrogen and progestogen but the inherent risks should be acknowledged. Both disorders have been correlated to menstrual irregularity. Amenorrhea in many women may be precipitated by simple psychological events such as leaving home, while severely stressful events produce a higher incidence. Unless a physiological factor such as malnutrition is operating, menses usually recur spontaneously within a few months. Amenorrhea is a constant feature of anorexia nervosa and may precede related attitudes toward eating and body weight. This syndrome is best regarded as a chronic and often severe neurotic disorder requiring combined physiological and psychological treatment, although some evidence exists to indicate an endocrine disorder. Extensive basic research is needed on the complex relationship between the neuroendocrine system and emotion.

The aim of the study was to evaluate concentration and activity of C1 esterase inhibitor (C1 INH) in patients with aspirin-sensitive urticaria. Deficiency of C1 INH is the basis for hereditary angioneurotic oedema. The study was performed in 32 subjects with aspirin-sensitive urticaria. The value of C1 INH in examined patients was the same as in control group. It seems there is no coexistence of aspirin-sensitive urticaria and C1 esterase inhibitor deficiency.

Food intolerance is a reproducible adverse reaction to a specific food ingredient that is not psychologically based. Food allergy is a form of food intolerance in which there is evidence that the response is caused by an immunological reaction to food. Other mechanisms of food intolerance include enzyme defects (e.g. lactase deficiency), pharmacological effects (e.g. histamine), toxic properties (e.g. haemagglutinating lectins) and irritants (e.g. spices). Food allergy in children is a highly contentious subject and there is often a striking lack of published evidence from which to base clinical decisions. The true prevalence of food allergy in children is unknown, although there is evidence of an increasing incidence of allergic reactions to some foods, especially peanuts. Our understanding of why some children are unable to tolerate certain foods (e.g. cow's milk, egg), or how they grow out of this intolerance, is very poor. Symptoms of food allergy in children are diverse and include vomiting, poor weight gain, abdominal pain, malabsorption, cough, wheeze, rhinitis, atopic eczema, urticaria and angioedema. Despite the lack of objective data to support the notion that food intolerance contributes to behaviour in children, this is a belief firmly held by many parents and some professionals. The gold standard for diagnosing food intolerance is the double-blind placebo-controlled food challenge (DBPCFC). There is often a poor correlation between the results of food provocation tests and those of skin prick tests of radioallergosorbent tests for specific food antibodies. For proven food allergy, elimination diets are the mainstay of management. In children these must be closely supervised to avoid nutritional deficiency and compromise of growth. Some children who have had severe (anaphylactic) reactions after food need to have a supply of self-injectable adrenaline made available to their parents and teachers and must also practice strict avoidance of the offending food.

Urticaria and angioedema symptoms result primarily from the physiological actions of histamine. Some individuals with urticaria have a decreased ability to degrade dietary histamine before it enters the circulation. Foods high in histamine, such as fermented foods, may exacerbate urticaria and angioedema in these individuals. Certain food additives may increase endogenous release of histamine and urticaria and angioedema symptoms. The objective of this study was to evaluate the effect of a histamine-reducing diet on urticaria and angioedema symptoms, and on nutrient intake. Nineteen subjects with chronic urticaria or angioedema were randomized to a treatment group (n=9) or a control group (n=10). The treatment group followed a histamine-reducing diet, and the control group eliminated artificial sweeteners from their diets. The subjects recorded antihistamine medication intake, number of wheals, the severity of pruritus and the severity of angioedema for two weeks before starting the diet and for six weeks during the dietary intervention. Subjects completed three-day food records every two weeks. There was a marginally significant decrease in the number of antihistamine tablets taken in the histamine-reducing diet group compared with the control group, and two of nine treatment subjects had dramatically improved symptoms. During the study there was no significant risk of nutritional deficiency for either group.

The sexually transmitted disease (STD), chancroid, is the greatest factor for HIV infections in Africa like syphilis is in the US. 3 physicians suggest that reducing the incidence of STDs may reduce the spread of HIV. Risk factors for HIV include current or history of STD in women and bisexual men, pelvic inflammatory disease, semen, copper releasing IUDs, contraceptive dermatitis, malnutrition/food allergy, environmental pollutants, genetic make up, and prostitutes. HIV infected persons should use condoms to not only protect partners but to prevent repeated contact with HIV which influences the clinical outcome. Condom use for contraception is not widely practiced in some areas, however, including Central Africa and Haiti. Condom use has increased in the US because IUDs have been removed from the market, fear of HIV infection, and discontinued use of oral contraceptives in older women. Urticarial reactions secondary to a copper IUD often occur in adolescent women, but clears when the IUD is removed. Traces of nickel in the copper wire used in IUDs often induce an allergic reaction. Allergic reactions are cofactors of HIV which can be made worse if coupled with excessive menstrual bleeding and HIV infected semen cells entering the uterus via the IUD tail. Many countries have integrated family planning services with other public health services, such as STD clinics that address AIDS. Integrated services should provide STD services and contraception and involve males and be accessible to them. Comprehensive school based clinical model should be implemented into schools and colleges. Counselors should advice HIV infected women not to have any more children. These women should get top priority to family planning services. HIV antibody testing for women should be done at any center where women may be including family planning centers and prisons.

This study was undertaken to determine the pattern of dermatoses in children in south India. All children <14 years presenting to us between May 2001 and June 2002 were recruited. A total of 2100 children (males -995; females- 1105) with 2144 dermatoses were recorded. Infections and infestations were the most common dermatoses (54.5%) followed by dermatitis and eczema (8.6%), pigmentary disorders (5.7%), insect bite reaction (5.27%), hair and nail disorders (5.2%), miliaria (4.1%), nutritional deficiency disorders (2.8%), urticaria (2.5%), genetic disorders (2.1%), psoriasis (1.4%), collagen vascular disorders (0.5%), hemangiomas (0.5%), drug eruptions (0.3%), pityriasis rosea (0.2%) and others (5.8%). Pyodermas were the most common dermatoses (47.13%) followed by scabies (30.6%) amongst infections and infestations. Atopic dermatitis was noticed only in 3 patients. Insect bite reactions (papular urticaria) (5.27%) and miliaria (4.1%) were attributed to the tropical weather conditions in this coastal area. Genetic disorders including ichthyosis and palmoplantar keratoderma contributed to 2.1% of cases and could be due to the high incidence of consanguinous marriages in this society.

In order to determine the epidemiological factors and clinical symptoms associated with Strongyloides stercoralis infection, we carried out a descriptive study with a control group in the District of Chanchamayo, Province of Chanchamayo, Junin, Peru. Group I (n = 50) represented those individuals with strongyloidosis and group II (n = 50) were those who tested negative for S. stercoralis by parasitological methods. Epidemiological variables significantly associated with group I were: bathing in the river 3-4 times per week, consuming non-drinking water, defecating in the field; and with group II: drinking boiled water, wearing sneakers and living in houses with cement floor. The clinical symptoms of epigastric pain, daily abdominal pain, semi liquid feces, liquid feces, daily defecation frequency, urticaria and nausea were significantly associated with group 1; whereas more solid feces and defecating every other day were significantly associated with group II. Among individuals under the age of 20 there was a higher percentage of malnutrition according to the weight-age index in group I (p = 0.045). We conclude that infection by S. stercoralis should be suspected in persons from tropical areas who are in frequent contact with rivers or streams or live close to watercourses, who have gastroenterological or dermatological symptoms or who are malnourished, especially if they are children or adolescents.

Food allergy is not the primary cause ofatopic dermatitis. This is illustrated in 3 patients with atopic dermatitis, a girl aged 6 months and 2 boys aged 6 and 7 months, respectively, who were referred to our outpatient clinic for evaluation for possible food allergies. All 3 patients were receiving hypoallergenic formula because their parents or health care providers suspected that the atopic dermatitis was caused by a cows' milk allergy. After sufficient explanation of the causes of atopic dermatitis and thorough clarification and use of topical therapy, a remarkable improvement in the severity of the atopic dermatitis was noted. Only 1 patient was allergic to cows' milk as confirmed by a double-blind, placebo-controlled food challenge, but there was no association with the level of eczema activity. It is a common misconception that food allergies and atopic dermatitis are always causally related. In recent years it has become clear that atopic dermatitis may result from defective skin barrier function, for which topical treatment is essential. Unjustified focus on food allergies as the primary cause ofatopic dermatitis increases the risk of unnecessary elimination diets and malnutrition. Only infants with acute allergic symptoms directly related to ingestion, i.e. urticaria and gastrointestinal symptoms, should be evaluated for food allergies by a double-blind, placebo-controlled food challenge.

Diet has an important role to play in many skin disorders, and dermatologists are frequently faced with the difficulty of separating myth from fact when it comes to dietary advice for their patients. Patients in India are often anxious about what foods to consume, and what to avoid, in the hope that, no matter how impractical or difficult this may be, following this dictum will cure their disease. There are certain disorders where one or more components in food are central to the pathogenesis, e.g. dermatitis herpetiformis, wherein dietary restrictions constitute the cornerstone of treatment. A brief list, although not comprehensive, of other disorders where diet may have a role to play includes atopic dermatitis, acne vulgaris, psoriasis vulgaris, pemphigus, urticaria, pruritus, allergic contact dermatitis, fish odor syndrome, toxic oil syndrome, fixed drug eruption, genetic and metabolic disorders (phenylketonuria, tyrosinemia, homocystinuria, galactosemia, Refsum's disease, G6PD deficiency, xanthomas, gout and porphyria), nutritional deficiency disorders (kwashiorkar, marasmus, phrynoderma, pellagra, scurvy, acrodermatitis enteropathica, carotenemia and lycopenemia) and miscellaneous disorders such as vitiligo, aphthous ulcers, cutaneous vasculitis and telogen effluvium. From a practical point of view, it will be useful for the dermatologist to keep some dietary information handy to deal with the occasional patient who does not seem to respond in spite of the best, scientific and evidence-based therapy.
