Association among Thyroid Dysfunction, Asthma, Allergic Rhinitis and Eczema in Children with Alopecia Areata
BACKGROUND: Alopecia areata is a non-scarring hair loss, which typically starts quickly. Atopy is one of the possible predisposing risk factors for this condition.AIM: This study aimed to evaluate the prevalence of thyroid disease, atopic dermatitis and allergic diseases in children with alopecia areata and compare the results with healthy individuals.METHODS: This case-control study was conducted on 50 patients with alopecia areata, diagnosed by a dermatologist, and 150 healthy individuals as the control group. Participants filled the questionnaires, and necessary tests were performed.RESULTS: In this study, the mean age of the participants was 2.55 ñ 14.26 and 3.19 ñ 11.92 in the case and control groups, respectively. Prevalence of asthma was 22% in the case group and 12.5% in control group (P = 0.109). Also, allergic rhinitis and eczema were observed in 20% and 22% of the subjects of the case group, whereas they were reported to be 8% and 10% in the control group (PV = 0.03 and 0.175, respectively). Moreover, 28% and 8% of the participants in the case and control groups had a family history of atopy and allergic disorders, respectively (P = 0.046). A significant difference was observed between the two groups regarding gender, type of delivery and contact with animals.CONCLUSIONS: According to the results of this study, a significant association was observed between the prevalence of alopecia areata and atopic conditions, such as allergic rhinitis and history of atopic dermatitis
Predominance of Trichophyton tonsurans causing tinea capitis: A 12-year retrospective study in the north of Iran
Background and purpose: Among different clinical entities of dermatophytosis, tinea capitis (TC) is considered a major public health challenge in the world, especially in regions with poor health and low income. Therefore, this study aimed to provide a retrospective analysis of the patients suspected of TC who were referred to the medical mycology laboratory of Mazandaran, a northern province of Iran.Materials and Methods: A retrospective analysis was performed on the patients suspected of TC who were referred to the medical mycology laboratory from July 2009 to April 2022. Hair roots and skin scrapings were collected from the participants. The laboratory diagnosis was confirmed by direct microscopic examination and culture. Finally, 921 out of 11095 (8.3%) patients were suspected of TC.Results: Based on the findings, TC was confirmed in 209 out of 921 patients (22.7%). In terms of gender, 209 TC patients (75.1%) were male. Moreover, the male to female ratio of TC patients was 1:3.0. Trichophyton tonsurans (146/174, 83.91%) was the most etiological agent,followed by T. mentagrophytes (13/174, 7.47%), T. violaceum (9/174, 5.17%), Microsporum canis (3/174, 1.71%), T. verrucosum (2/174, 1.15%) and T. rubrum (1/174, 0.57%). Besides, endothrix (77.0%) was the most prevalent type of hair invasion.Conclusion: The results revealed the predominance of T. tonsurans, as a causative agent of TC. Despite the prevalence of TC, the absence of appropriate consideration highlights that it is a neglected complication among children
Evaluation of the glycemic effect of methotrexate in psoriatic arthritis patients with metabolic syndrome: A pilot study
Methotrexate (MTX) is a systemic immunosuppressant drug used for the treatment of psoriasis and psoriatic arthritis. Previous studies demonstrated a potential association between psoriasis and diabetes mellitus, obesity, atherosclerosis, hypertension, eventuating into metabolic syndrome. This study aimed at exploring the glycemic effects of MTX in psoriatic arthritis (PsA) patients. In this prospective cross-sectional study, 27 patients with PsA were evaluated. The status of PsA and presence of accompanying metabolic syndrome was determined by standard criteria and indices. Blood indicators including HbA1c, erythrocyte sedimentation rate, fasting blood sugar, total cholesterol, high-density lipoprotein, triglycerides, and C-reactive protein were examined before and 12 weeks after MTX therapy. There were no significant changes between HbA1c levels before and after MTX therapy in both genders (men: P=0.131, women: P=0.803). In addition, HbA1c levels in PsA patients with metabolic syndrome were not different before and after treatment (P=0.250). Finally, HbA1c levels did not change in PsA patients without metabolic syndrome before and after therapy (P=0.506). MTX in PsA patients does not appear to have hyperglycaemic effects in the short-term and can be safely used in patients with metabolic syndrome and diabetes
Pediatric Viral Exanthema: A Review Article
Context:Â Many diseases caused by viral agents are associated with fever and cutaneous manifestations. Viral exanthema is a widespread nonspecific skin rash, commonly characterized by generalized eruption of erythematous macules and papular lesions. Although these rashes are mostly benign and self-limited, some may be serious and life-threatening. Differentiation between severe and benign types is clinically important and life-saving.
Evidence Acquisition:Â In this narrative review, electronic databases, including Google Scholar, Science Direct, PubMed (including Medline), Web of Science, Scientific Information Database, and Scopus, were searched. We conducted a narrative review of papers published on pediatric viral exanthema during 2000 - 2016. The used keywords included âviral exanthemaâ, âfeverâ, and âskin rashâ. Articles on skin rash, caused by drug reactions or nonviral exanthema, were excluded.
Results:Â Different viral agents can cause different types of skin reactions. Cutaneous manifestations and skin rashes can be categorized, based on the form of the rash (macular, papular, vesicular, blistery, petechial, and purpuric) or the general term, which denotes illnesses such as measles-like morbilliform rash, rubella or rubelliform rash, and scarlatiniform rash, a scarlet-fever like infection.
Conclusions:Â Based on the findings, a systematic approach relying on accurate history-taking and analysis of epidemiological cues and rash characteristics is of great significance
Should variation of serum lipid levels be considered a risk factor for the development of basal cell carcinoma?
Background: Basal cell carcinoma (BCC) is the most common cutaneous neoplasm in human beings. Ultraviolet radiation is one of the most important predisposing factors for BCC. Although some recent investigations have shown a high serum level of phospholipids in actinic keratosis and BCC, this subject is still debated and needs approval. This study aimed to evaluate the association between serum lipid level and development of cutaneous BCC.
Materials and Methods: In this case-control study, lipid profile including triglyceride (TG), Cholesterol (CHOL), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were measured in 30 patients with BCC and 30 healthy controls. Data were analyzed by descriptive statistical tests including t tests and Chi square test.
Results: This study shows that the mean age of the case and control groups were 63.93 ± 12.09 and 61.57 ± 21.1 years (mean ± SD), respectively. The average amount of triglyceride, cholesterol, HDL and LDL in the BCC patients were 139.73 ± 69.11 mg/dl, 179.20 ± 43.42 mg/dl, 39.40 ± 9.30 mg/dl and 110.70 ± 34.13 mg/dl, respectively, whereas these amounts in the control group were 141.83 ± 80.41 mg/dl, 173.60 ± 96.32 mg/dl, 36.97 ± 6.35 mg/dl, 110.70 ± 34.13 mg/dl and 104.87 ± 30.85 mg/dl, respectively. No significant difference was found in the lipid profile of the case and control groups (P > 0.05%).
Conclusion: This study shows that the serum lipid levels in patients with BCC has no significant difference in comparison with the control group and, therefore, relevance between BCC and serum lipid level is not proven. Further studies with a larger sample size are necessary for evaluating this subject

Vitiligo is one of the most primitive well-known dermatoid disorders with different suggested therapies. Therefore, this study investigated the efficiency and safety of topical tacrolimus in treatment of patients with vitiligo. This study was a clinical randomized designed study pre- post-test method, has been conducted on thirty cases with vitiligo who have referred to polyclinic and dermatology clinic. ParticipantâČs evaluated and demographic information recorded in designed checklist. In the next stage, the disease activity scored by vitiligo index disease activity system. Photography and depigmentation percent has recorded before treatment and further in 4 th , 8 th , 12 th , 16 th , 20 th , and 24 th weeks. Finally, gathered data compared through SPSS-20 software. The final sample comprised 30 persons including: 12 men (40%) and 18 women (60%). The average of patientâČs age in this study was 26/13 Î 18/20 (2-76-year-old). Eleven persons was â€15 years old and rest was older than 15. Sixty-six lesions have funded in patients that maximum has accrued on face and neck (37/87%) and trunk (21/21%). In addition, minimum of lesions is related to genitalia (9/09%). In the in 4 th , 8 th , 12 th , 16 th weeks, improvement in face and neck had increased significantly, into the past weeks. In the 20 th and 24 th weeks, the improvement has increased although it was not significant enhancement. Also about trunk, in the 4 th week the improvement does not have significant increasing in compare to the past week. In the eighth, 12 th , 16 th , 20 th , and 24 th weeks the improvement has been increased significantly in compare to the past weeks. Although in the case of limbs and genitalia, the improvement was lower. There was no significant difference between male and females and age. Although the improvement was, slow in older persons. Study results, has presented applying topical tacrolimus in vitiligo, particularly in face and neck, could be effective and does not seen any specified adverse effects during consumption of tacrolimus, it could be effective in decreasing effects in use of corticosteroid
Efficacy of a Gel from the Seed of Trigonella foenum-graceum L. in Preventing Trichoptilosis: A Randomized Placebo-Controlled Clinical Trial
Background and purpose: Trichoptilosis with fragility and hair loss is a common disorder, but, still there is no specific and effective treatment for this condition. The aim of this study was to evaluate the efficacy of gel from the seed of Trigonella foenum-graceum L. in prevention of trichoptilosis in people with trichoptilosis.
Materials and methods: A double-blind placebo controlled clinical trial was carried out in 60 people with trichoptilosis in Sari Touba Clinic affiliated with Mazandaran University of Medical Sciences. The participants received either T. foenum-graceum seed gel or placebo gel. The extract was prepared at 500 ÎŒg/ml and the treatment period was two months. Data were analyzed using Independent t-test, Paired t-test, Fisher's exact test, and Generalized estimating equations.
Results: In this study, the average rate of hair splitting in experimental group decreased significantly compared with the placebo group (P<0.001). Other factors such as dryness, fragility, and hair loss showed considerable decreasing rate in experimental group compared to the placebo group (Pâ€0.001, P<0.001, and P=0.042, respectively)
Conclusion: The positive effects of the herbal gel in reducing the incidence of trichoptilosis may probably be due to the presence of diosgenin and other steroidal saponins with antioxidant and anti-inflammatory effects.

Mycosis fungoides with Psoriasiform plaques: A case report and review of the literature
Abstract Mycosis fungoides (MF) is the most common variant of primary skin Tâcell lymphoma. It typically manifests as an indolent progressing cutaneous eruption with erythematous scaly patches or plaques. Due to the nonspecific pathological findings, it can be easily misdiagnosed as psoriasis. A 34âyearâold woman with a history of psoriasiform plaques for 12âyears was referred to our dermatology clinic. In the beginning, the diagnosis of psoriasis was made and topical steroids were prescribed: it did not exhibit any clinical improvement. During the visit, skin biopsy was performed and the diagnosis of MF was confirmed. Treatment with PUVA, prednisolon, methotrexate, topical ointment including ucerin, urea, and clobetasol were initiated. Significant improvement in all lesions were observed after 1âmonth of the treatment, and within a year, the disease improved dramatically after PUVA therapy. In refractory cases of psoriasiform plaques that are progressive and/or ulcerative despite the optimal treatment, biopsy is required and a possible diagnosis of MF should be kept in mind
