A unique case of a Chinese boy with Wiskott-Aldrich syndrome (WAS) associated with Takayasu's arteritis is reported. He had eczema, epistaxis and recurrent infections since early infancy and was found to have thrombocytopenia, negative delayed-type skin hypersensitivity, low T cell number and impaired lymphocyte proliferation to phytohaemagglutinin and concanavalin A. He had high normal serum immunoglobulin (Ig)G and IgA with low IgM and isohaemagglutinin. He presented with hypertensive encephalopathy at 5.5 years of age and an aortogram demonstrated abdominal aortic aneurysm with bilateral stenosis of renal arteries resulting in renovascular hypertension. His hypertension was difficult to control medically and autotransplant of his kidneys to the iliac arteries was performed, but he died in the immediate postoperative period. The relationship between immunodeficiency and collagen-vascular disease was discussed.

The post-thrombotic syndrome which is caused by deep venous thrombosis and characterized by pain, oedema, pigmentation, eczema, lipodermatosis, varices and ulceration, is due to deficient function of the venous valves and/or obstruction of the deep veins with venous hypertension. The diagnosis may be established by investigation of the investigation of the muscular-venous pump by pletysmography or dynamic phlebography and invasive measurement of the venous pressure is not employed to any great extent. The results of valvuloplasty have, by and large, been negative. The main form of treatment is, therefore, conservative compressive bandaging which can reduce the symptoms, facilitate healing of venous ulcers and prevent recurrence of ulcers. It is emphasized, however, that this treatment must be continued consequently during the remainder of the patient's life, regardless of other treatment.

A statistical analysis of 1007 eczema case histories has revealed arterial hypertension, mostly in bacterial eczema, in 24.8% of patients. A close multiple-factor relationship between eczema clinical manifestations and course and the presence of concomitant hypertension was revealed. A direct correlation was detected between the patients' age, sex, clinical manifestations and involved skin area in eczema and the level of arterial pressure. The authors emphasize that the detected specificities of eczema course in the presence of hypertension indicate a certain relationship between these diseases involving manifest abnormalities in the skin microcirculatory bed.

The hypothesis that undescended testis is caused by an excess of maternal oestrogen in pregnancy has been tested indirectly in a case-control study comparing mothers of boys with undescended testis (83) and mothers of normal boys (129) born on the same day. The study concentrated on the gestation of the boys, but also investigated the mother's previous obstetric history and postnatal events in the boys. The hypothesis predicted that there should be an excess of nausea, vomiting and hypertension in mothers of cases, but in fact the pregnancies of the case and control mothers were similar in all respects except one. The exception was the increased liability of the mothers of cases to threatened abortion. Mothers of cases also had an increased tendency to miscarry in previous conceptions, a reduced number of deliberate terminations and evidence of decreased fertility. An alternative hypothesis is suggested which would explain these findings. This is that placental function is impaired in the gestation of affected boys and the secretion of human chorionic gonadotrophin is reduced. This leads to changes in fetal testicular function and possible maldescent. Those born with undescended testis were more likely to present to a general practitioner with illness in the first three years after birth and this difference was mainly due to asthma, eczema, jaundice and feeding difficulties.

This review of controlled outcome research on Autogenic Training complements the literature by pooling narrative and quantitative approaches, by including only studies with experimental controls, by integrating the English and German literature, and by adding research findings published since the last review. Whereas previous reviews have already reported positive effects of Autogenic Training for migraine, insomnia, and test anxiety, additional supportive findings for angina pectoris, asthma, childbirth, eczema, hypertension, infertility, Raynaud's disease, and recovery from myocardial infarction are discussed here. The impact of protocol variations on outcome is described, and the specificity of Autogenic Training relative to other stress management techniques is highlighted. Quantitative findings suggested that Autogenic Training was associated with medium-sized pre- to posttreatment effects ranging from d = .43 for biological indices of change to d = .58 for psychological and behavioral indices thus matching effect sizes for other biobehavioral treatment techniques like biofeedback and muscular relaxation. Length of treatment did not affect clinical outcome. The discussion emphasizes how narrative and quantitative strategies complement one another.

541 workers with long-term history of occupational contact with antibiotics and chemicals were examined by a dermatologist, ENT specialist, neuropathologist, surgeon, ophthalmologist. Many workers complained of occasional skin eruption, rhinitis, skin itching, sneezing, cough, Quincke's edema. Allergic examination revealed the presence of allergic symptoms (allergic dermatitis, itch, vasomotor rhinitis, chronic eczema, obstructive bronchitis, bronchial asthma, Quincke's edema, acute and chronic conjunctivitis) in 98 examinees. Somatic affections are represented by hypertension, chronic hepatitis, ulcer.

Topical corticosteroids are the standard treatment for hand eczema. However, in chronic forms of the disease they are often ineffective or lose their efficacy due to tachyphylaxis. In a previous open study cyclosporine showed efficacy in chronic hand eczema. The aim of this study was to compare oral cyclosporine at 3 mg/kg/day with topical 0.05% beta-methasone-17,21-dipropionate (BDP) cream in the treatment of chronic hand eczema. In a randomized, double-blind study 41 patients with chronic hand eczema resistant to conventional treatment were assigned to either cyclosporine or BDP for 6 weeks. Both cyclosporine and BDP improved the eczema. The total disease activity score decreased to 57% of baseline in the cyclosporine group (mean change -6, SD 4.3; p < 0.001) and to 58% of baseline in the BDP group (mean change -5.7, SD 4; p < 0.001) at the end of treatment. However, between the groups there was no significant difference. Adverse events occurred in 68% of the patients during cyclosporine and in 56% during BDP treatment. With cyclosporine no case of hypertension or increase in serum creatinine above normal levels was recorded. In two patients the serum creatinine levels increased to values 30% above their own baseline values. Relapses occurred to the same extent in both groups. Cyclosporine at 3 mg/kg/day is as effective as topical BDP in the treatment of chronic hand eczema. Low-dose cyclosporine could be useful as an alternative treatment for severe chronic hand eczema in patients unresponsive to conventional treatment.

Nutritional counseling is a common primary care intervention but few empirical data are available. This study analyzed morbidity in family medicine practices and the relevance of nutritional counseling. Morbidity data from the Nijmegen University family medicine Continuous Morbidity Registration were studied. Since 1967 four practices (seven family physicians) have recorded all new episodes of illness. Physicians were trained and supervised monthly in their coding and classification of morbidity with diagnostic criteria. Two experienced family physicians assessed the nutrition sensitivity of all 400 diagnostic rubrics of the classification list. Incidence and prevalence of all morbidity and of nutrition-sensitive morbidity were calculated. The most common (chronic) diseases in family practice were a mixture of diseases of organ and body systems: hypertension, obesity, cardiovascular disease, chronic arthritis, asthma, chronic obstructive pulmonary disease, eczema, and diabetes mellitus. The prevalence of these diseases gradually increased in the past decade. Forty-eight diagnostic rubrics were considered to be nutrition sensitive, accounting for 16.5% of diagnoses recorded. Their prevalence also increased in the past decade. The survey supports the importance of nutrition-related interventions in family medicine but underlines that these interventions are directed at a variety of illnesses and patient groups. Common nutritional intervention techniques that can be applied in the personal care of patients in the context of their family life should be developed.

The prevalence of varicose veins (VV) in the elderly population of the Campania Region, in Southern Italy, was estimated. A random sample of the people aged more than 65 years was drawn by means of a stratified multistage sampling design warranting that observed percentages were direct estimates of population percentages. The investigation covered 1319 subjects, 560 (42.5%) men and 759 (57.5%) women, their ages ranging from 66 to 96 years with an average value of 74.2 years, who were interviewed and visited by trained physicians. VV were defined as any reticular or truncal visible varicosities of the lower limbs, and investigated symptoms were heaviness, pain, nightly cramps, edema, eczema, hyperpigmentation, and ulceration. Some variables were studied as risk factors: age, sex, lifetime occupation, smoking, alcohol, hypertension, diabetes, and obesity; previous treatment and use of elastic stockings were also studied. Statistical associations were evaluated by Chi-square test, a two-tailed P value of 0.05 being assumed as significance level. In total, 391 (29.6%) subjects were reported to be affected by VV, but the clinical examination was positive in only 362 (27.4%) with a good correspondence between answers and clinical findings. Prevalence was greatly affected by sex, the percentage being two times higher in women (35.2%) than in men (17%). VV developed after a pregnancy in 40.5% of women, but a high percentage of women (38.2%) also reported menopause as a time starting point. No significant association between reported risk factors and VV was found among men, whereas obesity was strongly related to VV in women. One or more symptoms were reported in 92.1% of persons affected by VV, but no previous therapy was reported by 58.9% of subjects. Only 16.9% of patients used elastic stockings with a significant difference between men (7.4%) and women (20.2%).

Growth factors produced by a variety of cells act as signalling peptides through specific cell surface receptor pathways. Functions such as cell proliferation, migration and differentiation have been assigned to each of them. Here, we report alterations of platelet-derived growth factor receptor alpha (PDGFR-alpha) and beta (PDGFR-beta) and vascular endothelial growth factor (VEGF) expression patterns in the progressive clinical stages of chronic venous insufficiency (CVI). A total of 30 punch biopsies were taken from patients with CVI, and VEGF and PDGFR were detected by indirect immunofluorescence and immunoperoxidase techniques. PDGFR-alpha and PDGFR-beta expression was strongly increased in endothelial cells of capillaries, pericapillary cells and connective tissue cells in the stroma of the skin of venous eczema and venous leg ulcer patients, and to a smaller extend in the dermis of those with lipodermatosclerosis. VEGF staining showed a similar expression pattern in the progressive CVI stages. However, staining of vessels in particular might simply reflect binding of VEGF, secreted by keratinocytes or fibroblasts, to its receptors. Growth factor and receptor expression in specimens from telangiectases and reticular veins, and from pigmented areas, resembled that of normal skin. We conclude that PDGFR-alpha, PDGFR-beta and VEGF play an important role in mediating inflammation and epithelial hyperproliferation in venous eczema, inducing connective tissue sclerosis in lipodermatosclerosis, and causing the reduced reepithelialization tendency in venous ulcers. We speculate that endothelial proliferation with chronic venous hypertension might be mediated by these growth factors.
