Context:Alopecia areata (AA) is a common form of localized, non-scarring hair loss. The etiopathogenesis of the disease is still unclear, but the role of autoimmunity is strongly suggested. AA is commonly associated with various autoimmune disorders; the most frequent among them is autoimmune thyroid disorders.Aim:To determine whether AA is associated with thyroid autoimmunity or thyroid function abnormalities in Egyptian patients.Materials and Methods:Fifty subjects with AA (37 males and 13 females) without clinical evidence of thyroid disorders were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital, Menoufiya Governorate, Egypt, during the period from June 2009 to February 2010. They were divided into 3 groups according to severity of AA. Fifty age and sex-matched healthy volunteers (35 males and 15 females) were selected as a control group. Every case and control were subjected to history taking, complete general and dermatological examination. Venous blood samples were taken from cases and controls after taking their consents for measurement of thyroid stimulating hormone (TSH), free T3, freeT4 and detection of Anti-thyroglobulin Antibody (Tg-Ab) and Anti-thyroid Peroxidase Antibody (TPO-Ab).Results:Subclinical hypothyroidism was detected in 16% of cases. There were statistically significant differences between cases and controls regarding levels of TSH, free T3 and free T4. There were significant differences between cases and controls regarding the presence of Tg-Ab and TPO-Ab.Conclusions:Every patient with AA should be screened for thyroid functions and presence of thyroid autoantibodies even in absence of clinical manifestations suggestive of thyroid affection.

Background: Lipoid proteinosis (Urbach-Wiethe disease) is a rare progressive autosomal recessive disorder, characterized histologically by deposition of periodic acid Schiff-positive, diastase resistant, hyaline-like material into the skin, upper aerodigestive tract, and internal organs.

Tramadol, one of the most commonly abused drugs in Middle East, impacts spermatogenesis and disturbs reproductive hormones in animal studies. We aimed to investigate tramadol impact on sperm quality and on levels of testosterone, prolactin and gonadotropins, in tramadol abusers (n = 30) to age-matched control (n = 30). Abusers had significantly low percentages of sperm motility, normal forms and vitality compared with control (95% CI -40.7 to -19.3, -13.5 to -9.3 and -31.9 to -9.7 respectively). Hypoandrogenism (95% CI -4.5 to -2.8), hyperprolactinaemia (CI (95%) 4.9 to 9.4) and hypergonadotropinaemia (95% CI 2.9 to 7.2 for FSH and 2.0 to 7.8 for LH) were observed in tramadol abusers vs controls. Smokers (26 of 30), concurrently abusing other drugs (11 of 30) and asymptomatic leucocytospermic (15 of 30) patients subgroups significantly abused tramadol beyond 3 years (p = .02, <.001, = .03 respectively) and in excess >450 mg/day (p = .02, = .01, = .005 respectively). Progressive motility (a + b%) was significantly low in young men <25 years old (p = .03) subgroup. Tramadol abuse is associated with poor sperm quality, hyperprolactinaemia and hypergonadotropic hypogonadism. We recommend semen analysis for tramadol long-intakes, question sperm donors and follow-up studies to prevent and reverse tramadol-induced testicular damage.

Context:Alopecia areata (AA) is a common form of localized, non-scarring hair loss. The pathogenesis of the disease is unknown. Previous evidence suggested the involvement of Th2 cytokines in disease pathogenesis.Aim:To determine serum level of total IgE, this is mainly influenced by Th2 cytokines, in Egyptian patients with AA.Materials and Methods:Fifty subjects with AA (28 males and 22 females) were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital from February 2012 to December 2012. Subjects with other conditions that might elevate serum IgE were excluded from the study. Fifty age- and sex-matched healthy subjects were selected as a control group. Venous blood samples were taken from cases and controls for measurement of total serum IgE by enzyme-linked immunosorbent assay. Skin biopsy was taken from every case from an active area of hair loss.Results:Total serum IgE was elevated in 27 (54%) cases. Its values among patients ranged from 13.5 IU/ml to 780 IU/ml. There was a statistically significant difference between cases and controls with regard to mean value of serum IgE (P < 0.05). Mean value of IgE did not vary significantly with disease severity, patients’ age, patients’ gender, disease duration, site of lesions, and positive family history of AA. No correlation was found between serum IgE levels and histopathological changes detected in examined cases.Conclusions:Total serum IgE is elevated in AA. This elevation is not related to age, gender, disease duration, disease severity, site of affection or family history of AA.

This study aimed to assess sperm DNA and RNA abnormalities in fertile and oligoasthenoteratozoospermic (OAT) smokers. In all, 140 subjects were included and classified into fertile nonsmokers, fertile smokers, OAT nonsmokers and OAT smokers. They were subjected to history taking, clinical examination, semen analysis, assessment of sperm DNA and RNA abnormalities. The results showed that an increased percentage of abnormal sperm DNA and RNA was demonstrated in fertile smokers compared with fertile nonsmokers and in OAT smokers compared with OAT nonsmokers. Increased percentage of severe, moderate sperm DNA and RNA damage was demonstrated in fertile heavy smokers compared with fertile light smokers and in OAT heavy smokers compared with OAT light smokers. It is concluded that smoking has a negative impact on sperm DNA and RNA abnormalities that is accentuated in heavy smokers compared with light smokers.

Background: Acne vulgaris (AV) is a common inflammatory skin disease involving dysfunction of the pilosebaceous unit. Many mechanisms for the pathogenesis of acne have been postulated. However, the precise pathogenesis is still uncertain.Objective: This study aimed to measure serum calprotectin levels in AV and to correlate its level with the activity and severity of the disease. Patients and methods: A total of 80 subjects were subdivided into two groups; group I included 40 patients complaining of AV with different severity levels, and group II had 40 healthy age and sex-matched participants as a control group. Serum calprotectin level was measured in both groups by the enzyme-linked immunosorbent assay (ELISA) method. Results: Serum calprotectin concentration was statistically significantly (p=0.0001) higher in the patient group when compared to the controls. There was a statistically significant (p = 0.001) difference among subgroups of patients according to disease severity regarding serum calprotectin concentration. There was a high-significant positive correlation between serum calprotectin concentration and disease severity. Calprotectin concentration could be used to diagnose AV with cutoff points higher than 1.03 ng/ml (with 77.5% sensitivity, 80% specificity) and also can detect its severity with cutoff points higher than 1.1 ng/ml with 96.3% sensitivity, 100% specificity to differentiate the mild cases from moderate and severe ones. Conclusion: Serum calprotectin concentration represents a valuable tool for diagnosing the inflammatory nature and monitoring the disease activity in AV patients.

Background Vitiligo is an acquired autoimmune skin disorder. The often-visible lesions of vitiligo have a major impact on patients’ quality of life and the results of the treatment regimens on offer are unsatisfactory, so there is a need for new therapeutic regimens. Recent advances in vitiligo pathogenesis have led to recognition of the importance of the JAK–STAT pathway as an attractive therapeutic option. Purpose To evaluate role of JAK1 and STAT3 in vitiligo. Methods This prospective case–control study was carried out on 35 patients presenting with vitiligo and 20 apparently healthy age- and sex-matched volunteers. Skin biopsies from controls and cases were taken for histopathological and immunohistochemical JAK1 and STAT3 evaluation. Results Epidermal and dermal overexpression of STAT3 was noted in lesional skin compared to the other groups ( P =0.02 and P <0.001, respectively). There was a positive correlation between dermal expression of JAK1 and dermal expression of STAT3 ( r =0.52, P =0.004). Conclusion In conjunction, JAK1 and STAT3 might be involved in the pathogenesis of vitiligo. This could open the gate for the use of JAK1 and STAT3 inhibitors as new targeted therapy for vitiligo.
