Childhood vitiligo

Introduction Vitiligo is an acquired, sometimes familial skin depigmentation disorder due to selective destruction of melanocytes. Vitiligo is primarily a disease of the young; in about half of patients it occurs before the age of twenty. The aim of this study was to investigate some epidemiological and clinical characteristics of vitiligo in children, in relation to adults with vitiligo and children without vitiligo. Material and methods The research was conducted in fifty children with clinically diagnosed vitiligo (2 to 16 years of age). Children were compared with control groups of children with other skin diseases (age 2 to 16) and with adults with vitiligo. Each group comprised 30 patients. A detailed history was obtained and physical examination performed in each patient to determine the age of onset, clinical type (segmental or generalized), family history of vitiligo and other autoimmune and/or endocrine diseases, association with halo nevi, poliosis and Koebner phenomenon. Results Of the 50 children with vitiligo, 29 (58%) were girls and 21 (42%) boys. The mean age at first visit was 9 years and the mean age of onset was 7 years. Children with vitiligo had positive family history of vitiligo and autoimmune and endocrine diseases more often compared to children without vitiligo (p<0.05). Children with vitiligo had poliosis, especially in cases of segmental vitiligo, more often compared to their age group (p<0.001). Children had an increased incidence of segmental vitiligo compared to adults (p<0.05). Halo nevi were more common in children with generalized vitiligo, in comparison with children without vitiligo (p<0.01) and adults with vitiligo (p<0.05). Discussion and conclusion Our results show that segmental vitiligo and halo nevi occurred significantly more often in children than adults with vitiligo.

Introduction Vitiligo is an acquired, sometimes familial skin depigmentation disorder. In about half of patients it occurs before the age of twenty. The aim of this study was to investigate the incidence and significance of autoantibodies (AT) and associated autoimmune and endocrine diseases in children with vitiligo, in relation to adults with vitiligo and children without vitiligo. Material and methods The research was conducted in fifty children with clinically diagnosed vitiligo from 2 to 16 years of age. Children were compared with control groups of children with other skin diseases (aged from 2 to 16) and with adults with vitiligo. Each group comprised 30 patients. A detailed history was obtained and physical examination was performed in each patient to determine presence of autoimmune and endocrine diseases in patients with family history of vitiligo. Routine blood examination, routine urinalysis and stool were performed in all patients. We evaluated the incidence of antinuclear (ANA) and antithyroid antibodies (ATA) in each patient, as well as the incidence of antibodies to gastric parietal cell (APCA), smooth muscle (SMA), cord (ACA) and mitochondrial antigens (AMA) in 38 children with vitiligo and in control groups. Results Children with vitiligo had positive family history of vitiligo more often compared to children without vitiligo (p<0.05). Presence of ANA, ATA, APCA, SMA, ACA and AMA was not considerably increased in children with vitiligo compared with their age group. ANA was more common in adults with vitiligo, in comparasion with children with vitiligo (p<0.05). None of the children with vitiligo had an associated autoimmune and endocrine disease in contrast to adults with vitiligo (p<0.05). Discussion and conclusion Several studies have shown a significant incidence of positive autoantibodies in children with vitiligo, compared to children without vitiligo. However, in our series, presence of ANA, ATA, APCA, SMA, ACA and AMA was not significantly increased in children with vitiligo, compared with children without vitiligo. Further studies are necessary in this area in order to draw more conclusions. In the previous studies, it has been established that children with vitiligo were generally healthy, whereas adults with vitiligo had an increased incidence of autoimmune and/or endocrine diseases. No studies have shown this association in children with vitiligo. Our results support findings of previous studies.

The Mean

Background: Childhood vitiligo although clinically similar to adult onset vitiligo but it has distinct clinical, epidemiological and prognostic features compared to adult onset vitiligo.Methods: This is a retrospective study that was carried out on 85 pediatric patients up to age of 18 years old with the diagnosis of vitiligo, where the clinical and epidemiological data including clinical type of vitiligo, family history of autoimmune diseases like thyroid disorders and diabetes mellitus and laboratory results including anti-thyroid peroxidase antibodies (anti-TPO antibodies), anti-parietal cell antibodies, antinuclear antibodies (ANA), Vitamin D and Vitamin B12 were retrieved from the files of these patients.Results: The mean age of the children affected by vitiligo was 10.4 years, the mean age of onset of vitiligo was 5.4 years, 54 (63.5%) percent were girls and 31 (36.5%) were boys. A positive family history of vitiligo was found in 44.7% of the participants, family history of DM was found in 64.7% of patients and family history of thyroid disease was found in 32.9% of the participants. The prevalence of thyroid autoimmunity was found to be in 22.4% of total participants.Conclusions: Childhood vitiligo has distinct clinical features, more common family history for autoimmune diseases and thyroid autoantibodies rather than overt clinical diseases, which raise the necessity to perform a routine initial immunological and thyroid screening in children with vitiligo and to repeat them at annual bases if there were abnormal values at base line or strong family history.

Aim: To find out the prevalence of psoriasis vulgaris and its associated risk factors. Study Design: Descriptive cross-sectional. Place and Duration of Study: Study was conducted at Rawalpindi Leprosy Hospital during January 2019 to December 2019. Methodology: The diagnosed cases of Psoriasis Vulgaris (PsV) were included in the study. All the patients were investigated on the basis of an in depth Performa. The Performa include all the relevant clinical and family history of the patient along with the personal details. Data was analyzed by using Statistical Package for the Social Sciences (SPSS) version 20. All the numerical variables were presented as mean with standard deviation while categorical data as frequency and percentages. The association of risk factors with the Psoriasis was calculated by using the Chi-square test. p-value less than 0.05 was considered as significant. Results: Mean age with standard deviation of patients was 34.7±14. Most of the diagnosed patients were male and below 40 years of age, only 4.2% cases were having positive family history of Psoriasis and found significant correlation. The frequency of onset of symptoms in adolescent was more as compared to childhood i.e. 95.3% and 4.7% respectively. Majority of psoriasis cases (65.3%) were from non-smoker group and having strong association with smoking. The frequency of arthritis among psoriasis patients was 23.7% and majority of the patients, who developed arthritis were those having age <40 year and were suffering from psoriasis since 5-10 years. Conclusion: Current study concluded that Psoriasis vulgar is having higher prevalence rate among male and below 40 years of age group. The results also suggested a strong association of severity of psoriasis with certain risk factors including family history, age of onset of symptoms, smoking and arthritis.

The Mean

Background: Psoriasis is a chronic disorder with the most common manifestation being the plaque-type. Nearly 20% of the plaque type suffer from a disease of moderate to severe intensity with immense effect on the quality of life. Aim was to study the clinical, socio-economic and demographic characteristics of patients with moderate to severe plaque type of psoriasis.Methods: This was an observational study conducted in about fourty patients diagnosed with moderate to severe plaque type of psoriasis based upon the clinical history, morphology of the lesions and assessed using psoriasis area and severity index (PASI), dermatology life quality index (DLQI) scoring and for comorbidities. Data was compiled and analyzed with statistical package for social science (SPSS) Version 20.0.Results: Mean age was 37.43±10.1 years. 22 were males (55%) and 18 were females (45%). The mean duration was 8.93 years and 15% had family history. The mean age of onset was earlier in the females (20.23 years) with a positive family history, as compared to males (25.36 years). About 62.5% had moderate psoriasis and 37.5% had severe psoriasis. At the baseline the PASI score was 31.98±6.08 and DLQI score was 36. About 67.5% had nail changes and 10% had psoriatic arthritis. Almost in half (47.5%) the duration of the disease was 1 to 5 years and scalp (32.5%) the most common initial site of involvement. Various comorbidities were documented, 72% in moderate psoriasis and 73.33% in severe psoriasis with dyslipidemia (67.5%) being commonest.Conclusions: Patients with moderate to severe psoriasis mostly have a low quality of life with multiple significant co-morbidities that increases the risk for morbidity and mortality.

Objective: To determine the role of hypertension, hyperlipidemia, smoking and positive family history of diabetes and hypertension in the development of diabetic retinopathy. Methods: This prospective cohort study was conducted at the Department of Chemical Pathology, Armed Forces Institute of Pathology, Rawalpindi over 2 years period from June 2014 to June 2016. One hundred consecutive diabetic patients with no signs of diabetic retinopathy and good glycemic control (HbA1c<6.5%) were registered by non-probability convenient sampling after taking written informed consent. They were evaluated for hypertension, hyperlipidemia and smoking status. These patients were then followed 6 monthly for 2 years to look for the development of diabetic retinopathy. Results: The mean age of the patients was 50.72±9.29 years and there were 57 (57%) male and 43 (43%) female patients. Majority (82%) of the patients had NIDDM. The mean duration of diabetes was 8.31±6.83 years. 11% of the patients were smoker, 37% were hypertensive, 6% had hyperlipidaemia, 62% had family history of diabetes and 30% had family history of hypertension. At the end of follow-up, 9 (9.0%) patients had diabetic retinopathy. The frequency of diabetic retinopathy increased with increasing age of the patient; however, the difference was statistically insignificant. A comparatively higher frequency of diabetic retinopathy was also seen in patients with IDDM and those with positive family history of diabetes and hypertension yet again, the difference was statistically insignificant. Also, no significant difference was noted among male and female genders and smokers vs. non-smoker. However, the frequency of diabetic retinopathy increased significantly with increasing duration of diabetes. It was also higher among those with hypertension and hyperlipidemia. Conclusion: Higher patient age (≥50 years), increasing duration of diabetes (≥20 years), insulin dependent diabetes mellitus, hypertension, hyperlipidemia, and positive family history of diabetes and hypertension were found to be associated with increased frequency of diabetic retinopathy.

Background: Type 2 diabetes mellitus (T2DM) is a commonly occurring chronic non communicable disease. Family history of diabetes is one of the important non modifiable risk factor for occurrence of the disease. This study was done to assess the percentage of positive family history of diabetes among T2DM patients and its association with age of onset and complications of diabetes. Methods: This is a descriptive cross sectional study done in an urban health training centre of a medical college. Using purposive sampling technique, 215 diabetic patients were selected as study participants. Data collection was done by structured questionnaire. Data analysis was done using SPSS 17. Results: Among the study participants, 62.3% were females. The mean age of the participants was 56.08±10.04. Nearly 68.8% of T2DM patients had family history of Diabetes, among them 25.1% of them had diabetic mother and 15.3% had diabetic father. Among the study group of T2DM patients, 51.6% had diabetic complications. The family history of diabetes with age of onset and complications had statistically significant association among the study group. Conclusions: This study shows that persons with positive family history of diabetes are more prone to early onset of diabetes and developing complications. So appropriate behavioural changes and modification must be practiced to delay or prevent the occurrence of the disease. Early diagnosis and treatment is a must to prevent the complications in the vulnerable people.

Abstract Background.—According to recently published data, prophylactic mastectomy (PM) appears to prevent about 90% of the expected malignant neoplasms in women with a family history of breast cancer. Objectives.—To identify the frequency of high-risk lesions in PM specimens and to determine occurrence of any new primary breast cancer following PM. Design.—We performed a retrospective study of women undergoing unilateral or bilateral PM. Medical charts and pathologic findings of 35 patients who underwent bilateral mastectomies at University Hospital, Syracuse, NY, from 1989 to 1996 were reviewed. Patients with biopsy-proven bilateral breast cancer were excluded. Patients were divided into 3 groups: (A) positive family history and no known breast cancer (n = 9), (B) positive family history and contralateral neoplasia (n = 13), and (C) negative family history and contralateral neoplasia (n = 13). These findings were compared with those found in reduction mammoplasty specimens from 10 women at standard risk of breast cancer. Results.—The mean age of the control group of women undergoing reduction mammoplasty was 38 years. The pathologic specimens demonstrated no significant pathologic findings in 9 and fibrocystic change in 1. In group A, the mean number of affected relatives was 3.1, and the mean age was 38 years. Two of these 9 women had atypical duct hyperplasia and 1 had atypical lobular hyperplasia in their breasts (ie, 33% with high-risk pathologic findings). Of the 13 group B women (mean age, 46.6 years; mean of 2.5 affected relatives and unilateral breast cancer), the contralateral PM specimen contained duct carcinoma in situ in one and invasive ductal cancer in a second (15% with occult malignant neoplasms). In 13 group C patients (mean age, 47.1 years), 3 (23.1%) of the contralateral PM specimens displayed atypical duct hyperplasia or atypical lobular hyperplasia. At a mean follow-up of 4.8 years, there have been no new breast malignant neoplasms in these 45 women. Conclusions.—The occurrence of unilateral cancer in patients with family history of breast cancer is associated with a 15.4% probability of simultaneous occult malignant neoplasms in the contralateral breast. Patients with a strong family history but no evidence of breast cancer have a substantially similar rate of proliferative disease in their PM specimens as those women who have unilateral cancer but no significant family history.

Objective: To study the clinical features and associated factors of female pattern hair loss (FPHL) in premenopausal and menopausal women patients. Materials and Methods: This is a retrospective chart review of FPHL patients visited hair clinic, Siriraj Hospital from June 2012 to May 2015. Demographic data, family history and history of hair loss were evaluated. Factors associated with FPHL were analysed. Results: There were 267 patients (180 premenopausal women and 87 menopausal women) in this study. The mean age of onset of patients was 35.5±12 years (premenopausal FPHL) and 60.5±7 years (menopausal FPHL). Positive family history of androgenetic alopecia (AGA) was 48.3%, mainly in first-degree relatives. The data showed an increased incidence of FPHL with advancing age. The most common presentation is Ludwig grade I. The study showed that patients also have dyslipidemia (16.9%), hypertension (16.5%), diabetes mellitus (10.9%), hypothyroidism (4.9%), anemia (3.7%), and hyperthyroidism (2.9%). In multivariate analysis, significant associations were found between low ferritin level < 70 µg/L and premenopausal FPHL (OR 5.51, 95% CI 2.26-15.14, P = 0.01). Conclusion: Maternal family history of AGA seems to have a greater influence on premenopausal FPHL. Low serum ferritin levels < 70 µg/L were significantly associated with FPHL in premenopausal women.
