CDLQI-based Assessment of Skin Disorders Among Children: A Study from Northern India.

Background: Skin is the largest organ of the human body, and one of the most sensitive indicators of a child's general health. Skin disorders, especially among children, may cause an additional emotional and psychological stress to the patients and their family. Aim: We aim to compare the extent to which various skin diseases affect the quality of life among the pediatric age group (5-12 years) based on Children's Dermatology Life Quality Index (CDLQI) scores. Materials and Methods: A cross-sectional study of 453 patients who attended skin clinic at a regional hospital in Northern India between November 2015 and May 2017. The study consists of questions regarding dermatoses. Patients were evaluated using a standardized pro forma and a CDLQI questionnaire. The diseases with abnormal high proportions were evaluated by the control chart technique. Results: Out of a total of 453 pediatric patients identified for dermatoses, the average quality of life based on the CDLQI score did not show significant variation across different seasons (P < 0.522). Although the type of skin disorders (P < 0.001) had a significant effect on the quality of life of the children. Based on the CDLQI scores, following diseases have a significant adverse effect on quality of life of the patients - miliaria, atopic dermatitis, scabies, impetigo, and pediculosis capitis. Conclusion: Our study has shown that skin diseases, irrespective of the type, adversely impair the quality of life of the child and in turn the family, therefore, calls for an enhanced level of compassion and care.

Comparative Efficacy of 10% Sodium Hydroxide, 88% Phenol, and 90% Trichloroacetic Acid as Chemical Cauterants for Partial Matricectomy in the Management of Great Toe Nail Onychocryptosis.

CONTEXT: Lateral plate avulsion with chemical matricectomy is the treatment of choice for ingrown toenails. Phenol is the most widely used cauterant, followed by 10% NaOH and more recently trichloroacetic acid. AIMS: To evaluate the efficacy of 10% NaOH, 88% Phenol, and 90% TCA in cauterizing the matrix with regular follow up post surgery and clinical photographs. MATERIALS AND METHODS: Fifteen adult patients presenting with ingrowing toe nails were recruited to the study with prior consent. The NaOH group (Group A) had five patients and five nails treated, the phenol group (Group B) had five patients and six nails treated, and the TCA group (Group C) had five patients and six nails treated. A total of 17 great toe nails were treated. Following proximal digital block and partial nail avulsion, the matrix was curetted and the lateral horn cauterized with 10% NaOH (1 min), 88% phenol (3 min), and 90% TCA (3 min). Post-procedure follow-up was done at weekly intervals to evaluate post-operative pain, oozing, and wound healing. STATISTICAL ANALYSIS USED: Graph pad prism software was used for statistical analysis. ANOVA tests were used to test the statistical significance between post-operative parameters of each group. RESULTS: Mean duration of post-op pain in Group A was 4.2 days; Group B was 8.6 days, and Group C was 1.2 days. Oozing occurred for a mean duration of 10.6 days in Group A, 14 days in Group B, and 5.6 days in Group C. Mean duration of tissue re-epithelization was 28.4 days in Group A, 40.5 days in Group B, and 27.4 days in Group C. CONCLUSIONS: TCA is an effective cauterant for chemical matricectomy with the advantage of less duration of post-op pain and faster healing.

A Study on Ocular Morbidity among Patients with Psoriasis Visiting a Tertiary Care Hospital in Karnataka, Southern India.

Introduction: Psoriasis is a chronic immune-mediated disorder with predominantly dermatological manifestations and varying prevalence in different parts of the world. Data on the ocular features of this disease are limited. Hence, we aimed to estimate the burden of ocular disease in psoriatic patients in the Indian population. Materials and methods: An interdisciplinary cross-sectional hospital-based observational study was conducted in South India, wherein an ophthalmological evaluation was performed for the patients with Psoriasis. The ocular features were recorded and compared with the severity of psoriasis using the Psoriasis Area Severity Index (PASI) score. Results: Ocular morbidity was observed in 80% of the patients with psoriasis which increased with increasing duration (p = 0.004) and increasing PASI score (p < 0.001). Blepharitis and dry eye disease were common in our patients with psoriasis. Conclusion: It is important to screen patients with psoriasis for ocular comorbidities so as to prevent sight-threatening complications.

Multiple trichofolliculomas mimicking multiple trichoepitheliomas.

Trichofolliculomas are benign hair follicle hamartomas which were initially considered as hair follicle tumors. Usually presenting as a solitary lesion associated with a tuft of vellus hairs, multiple trichofolliculomas are rare. Trichofolliculomas are characterized by a histopathological feature of dermal keratin cyst with cyst wall showing radiating hair follicles. We report this case for the rare presentation of multiple trichofolliculomas on the face which clinically mimicked multiple trichoepitheliomas.

Development of Small Molecular Proteasome Inhibitors Using a Caenorhabditis elegans Screen.

We have developed a screening protocol to identify compounds with characteristics of small molecule proteasome inhibitors using the real-time analysis of the Caenorhabditis elegans germ line. This screen is able to identify compounds that induce germ line phenotypes characteristic of a reduction in proteasome function such as changes in polarity, aberrant nuclear morphology, and stimulation of apoptosis. This basic protocol is amenable to a high throughput (96-well) format and has been used successfully to identify multiple compounds for further analysis based on structural elements from the naturally occurring compounds lactacystin and the ß-lactone homologs omuralide and salinosporamide A. The further development of this assay system should allow for the generation of novel small molecule proteasome inhibitors in a genetically tractable whole animal amenable to biochemical analysis.

Analysis of prostate-specific antigen transcripts in chimpanzees, cynomolgus monkeys, baboons, and African green monkeys.

The function of prostate-specific antigen (PSA) is to liquefy the semen coagulum so that the released sperm can fuse with the ovum. Fifteen spliced variants of the PSA gene have been reported in humans, but little is known about alternative splicing in nonhuman primates. Positive selection has been reported in sex- and reproductive-related genes from sea urchins to Drosophila to humans; however, there are few studies of adaptive evolution of the PSA gene. Here, using polymerase chain reaction (PCR) product cloning and sequencing, we study PSA transcript variant heterogeneity in the prostates of chimpanzees (Pan troglodytes), cynomolgus monkeys (Macaca fascicularis), baboons (Papio hamadryas anubis), and African green monkeys (Chlorocebus aethiops). Six PSA variants were identified in the chimpanzee prostate, but only two variants were found in cynomolgus monkeys, baboons, and African green monkeys. In the chimpanzee the full-length transcript is expressed at the same magnitude as the transcripts that retain intron 3. We have found previously unidentified splice variants of the PSA gene, some of which might be linked to disease conditions. Selection on the PSA gene was studied in 11 primate species by computational methods using the sequences reported here for African green monkey, cynomolgus monkey, baboon, and chimpanzee and other sequences available in public databases. A codon-based analysis (dN/dS) of the PSA gene identified potential adaptive evolution at five residue sites (Arg45, Lys70, Gln144, Pro189, and Thr203).

Efficacy and safety of erbium-doped yttrium aluminium garnet fractional resurfacing laser for treatment of facial acne scars.

BACKGROUND: Treatment of acne scars with ablative fractional laser resurfacing has given good improvement. But, data on Indian skin are limited. A study comparing qualitative, quantitative, and subjective assessments is also lacking. AIM: Our aim was to assess the improvement of facial acne scars with Erbium-doped Yttrium Aluminium Garnet (Er:YAG) 2940 nm fractional laser resurfacing and its adverse effects in 25 patients at a tertiary care teaching hospital. METHODS: All 25 patients received four treatment sessions with Er:YAG fractional laser at 1-month interval. The laser parameters were kept constant for each of the four sittings in all patients. Qualitative and quantitative assessments were done using Goodman and Barron grading. Subjective assessment in percentage of improvement was also documented 1 month after each session. Photographs were taken before each treatment session and 1 month after the final session. Two unbiased dermatologists performed independent clinical assessments by comparing the photographs. The kappa statistics was used to monitor the agreement between the dermatologists and patients. RESULTS: Most patients (96%) showed atleast fair improvement. Rolling and superficial box scars showed higher significant improvement when compared with ice pick and deep box scars. Patient's satisfaction of improvement was higher when compared to physician's observations. No serious adverse effects were noted with exacerbation of acne lesions forming the majority. CONCLUSION: Ablative fractional photothermolysis is both effective and safe treatment for atrophic acne scars in Indian skin.Precise evaluation of acne scar treatment can be done by taking consistent digital photographs.

Laptop induced erythema ab igne.

Erythema ab igne is a reticular, pigmented dermatosis caused by prolonged and repeated exposure to infrared radiation that is insufficient to produce a burn. The use of laptop computers has increased manifold in the recent past. Prolonged contact of the laptop with the skin can lead to the development of erythema ab igne. We present a case of erythema ab igne secondary to laptop use in an Indian student.
