RESUMEN
Skin diseases in children are encountered frequently and their characterization is essential for the preparation of academic, research and health plans. A retrospective study was designed to evaluate the epidemiologic features of pediatric dermatoses in India. The setting was a tertiary care referral center in India (Kalawati Saran Children's Hospital, New Delhi) during January 1997 to December 2003. A total of 30,078 children less than 12 years of age with 32,341 new dermatoses were recorded, with a male to female ratio of 1.07:1. Most of the disease was seen in the 1- to 5-year age group (44.94%). The most common skin diseases were infections and infestations (47.15%) consisting of bacterial infections (58.09%) and scabies (21.54%), followed by eczemas (26.95%), infantile seborrheic dermatitis, scabies, and pityriasis alba. Other unique dermatoses in our settings were papular uticaria (3.59%), miliaria (5.46%), postinflammatory pigmentary abnormalities (1.68%), and nutritional deficiency dermatoses (0.45%). A majority of patients were diagnosed clinically and special diagnostic tests were conducted in 2.6% of patients. The most common diagnostic test used was KOH mount (59.2%), followed by skin biopsy (39%). Nearly 90% of patients were seen without any referral and in the remaining, a majority were referred by pediatricians (75%). A majority of patients were diagnosed to have infection followed by dermatitis in our setting.

The present study highlights the role of fine-needle aspiration cytology (FNAC) and Ziehl Neelsen (ZN) staining in diagnosis of cutaneous tuberculosis and correlates the cytomorphological features with histopathology.FNAC and biopsy was performed on 30 cases of cutaneous tuberculosis and along with the routine stains, ZN and periodic acid Schiffs staining was carried out in all cases. On cytology, out of 9 cases of lupus vulgaris, 89% showed cohesive epithelioid cell granulomas with or without chronic inflammatory infiltrate; however, acid fast bacilli (AFB) could be demonstrated only in 22.2% on cytology while none on histopathology. Of 19 cases diagnosed as Scrofuloderma, 79% showed caseation necrosis with or without granulomas, 10.5% revealed granulomas with acute inflammatory infiltrates. AFB was demonstrated in 78.9% cases on cytology when compared with 15.8% on histopathology. No conclusion could be drawn in one case each of TBVC and lichen scrofulosorum.Hence, correlating cytomorphological patterns with clinical presentations often yields diagnostic information in cases of cutaneous tuberculosis and frequently obviates the need for biopsy especially in cases of scrofuloderma.

OBJECTIVES: Sexually transmitted diseases (STDs) and anogenital cancers are the major health problems in Indian women but no reliable estimate of the prevalence of either genital chlamydial infection or human papillomavirus (HPV) infection in STD patients is available. The aim of this study was to detect the frequency of Chlamydia trachomatis and the most prevalent high-risk HPV type 16 (HPV 16) infection in Indian women, with STDs and precancerous and cancerous lesions of the uterine cervix by polymerase chain reaction (PCR), and their comparison with those of conventional serology and antigen tests used for C. trachomatis detection. METHODS: Endocervical swabs or scrapes were collected from 50 women with STDs and 30 normal healthy women attending the STD clinics of Smt. Sucheta Kripalani Hospital, New Delhi. Scraped cervical cell specimens were also collected from 50 women with precancerous and cancerous lesions of the uterine cervix. Detection of C. trachomatis and HPV was carried out by PCR using chlamydia and HPV genome-specific oligonucleotide primers. The detection of chlamydial antigen and IgG-specific antibodies was carried out by enzyme immunoassay (EIA) and serological enzyme-linked immunosorbent assay (ELISA), respectively. RESULTS: A chlamydia plasmid-based PCR assay detected 50% (25 of 50) positivity of C. trachomatis in STD patients and HPV 16 DNA was found in 30% (15 of 50) of these cases which are significantly higher than those found in healthy controls. The PCR estimate of chlamydia was found to be higher than its reported frequency by tissue culture. The EIA could detect chlamydial antigen in only 13 cases (26%) while serological ELISA revealed evidence of chlamydia IgG-specific antibodies in 26 (52%) cases. Interestingly, in women with precancerous and cancerous lesions, the rate of HPV 16 infection was very high (52% and 72%, respectively), whereas the frequency of chlamydia infection was found to be 12-22% only. Occurrence of other sexually transmitted agents was also evaluated in the women. CONCLUSIONS: This is the first PCR estimate of genital chlamydial (50%) and HPV 16 (30%) infection in STD patients and women with precancerous and cancerous lesions of the uterine cervix in India. The PCR method seems to be a good alternative to tissue culture.

The psychiatric morbidity in psoriasis patients was compared with that in vitiligo patients using the standardised Hindi (vernacular language) version of the General Health Questionnaire (GHQ-H). Thirty new and untreated patients each with psoriasis or vitiligo and between the ages of 18-60 yrs, constituted the study group. The prevalences of psychiatric morbidity as assessed by the GHQ-H were found to be 53.3% and 16.22% in the psoriasis and vitiligo patients respectively; the difference was statistically significant (p=0.0028). The prevalences of depression were 23.3% and 10% in psoriasis and vitiligo respectively and anxiety was observed in 3.3% of each group. Sleep disturbance was the most common complaint and was present in 56.6% of psoriasis patients and 20% of the vitiligo patients. However, the parameter of sleep disturbance showed a statistically significant difference between the two dermatoses (p=0.0034).

Tuberculosis of the vulva is a rare condition usually seen by a gynecologist. We report a case of chronic ulcer on the vulva of four months duration, which, on detailed investigation, turned out to be a case of primary inoculation tuberculosis. The patient was subsequently put on antitubercular therapy with a good the therapeutic response. The rarity of this presentation in dermato-venereology is emphasized.

Although there are various published studies on erythroderma from western and Asian countries, most of them have only included patients in the adult age groups. As we have an exclusively pediatric dermatology unit, we thought it would be intriguing to study the clinical, etiological and laboratory parameters of erythroderma in children. Seventeen erythroderma patients of both sexes were inducted into the study between 1993 to 1998. The mean age of onset was 3.3 years and the male:female ratio was 0.89:1. Eight (47%) of the patients were infants; 9 (53%) others belonged to the preschool and school going age group (age range between 1 to 12 years). An acute onset of the disease was seen in 47% of the patients while 53% of the patients had a chronic onset. The main presenting complaints were itching in 41% and burning in 18% of patients. Scalp involvement (71%), nail involvement (18%), and alopecia (6%) were the main cutaneous features observed while fever (53%), tachycardia (53%), pedal edema (12%), lymphadenopathy (18%), and hepatomegaly (12%) were the main systemic features observed in this study. Etiologically, drugs (29%), showed the highest incidence, followed equally (18%) by genodermatoses, psoriasis, and staphylococcal scalded skin syndrome (SSSS). Two (12%) patients had erythroderma due to atopic dermatitis, while one was (5%) due to infantile seborrheic dermatitis coexisting with dermatophytosis. Laboratory parameters contributed little towards diagnosis of the underlying dermatological condition. Thus, though erythroderma is a striking entity, it is yet uncommon in the pediatric age group. Because the drug induced group was the largest in this study, we recommend that drugs should be suspected as important causative factors of erythroderma in children.

Proptosis due to an extraconal orbital abscess of tubercular origin with lacrimal gland involvement, representing ocular scrofuloderma, is a rare entity. This association has not been reported earlier in the literature. We describe a 7-year-old boy who presented with nodulo-ulcerative lesions of tubercular etiology with discharging sinuses on right side of the face and a similar lesion on the right lower eyelid along with proptosis of 4 months duration. Computerized tomography (CT) scan of the head confirmed the extraconal, intraorbital, hyperdense, homogeneously enhancing mass separated from the lateral rectus muscle and further revealed involvement of lacrimal gland along with erosion of the temporal bone. The patient showed marked improvement of his dermatological and ophthalmological lesions with anti-tubercular treatment. Subsequent ultrasound examinations of the orbit revealed regression in the size of the abscess from 10.7 mm to 5.0 mm and then complete disappearance of the abscess obviating surgical intervention.

One hundred cases of pyodermas in children were investigated clinically and bacteriologically. Nasal and throat swabs from all cases were subjected to bacteriological examination. Most of the children (42%) were in the 1-4 year age group. The majority (58%) belonged to lower socio-economic groups with poor standards of hygiene. A history of over-crowding was obtained from 87% of cases, 82% were undernourished. Most of the children (68%) reported during the hot and humid months of June, July, August, and September. Primary pyodermas were observed in 72% of the children, and secondary pyodermas in 28%. Impetigo was the commonest primary pyoderma (48.61%); among secondary pyodermas, infected scabies was noted predominantly (42.86%). The face and legs were more commonly involved. Bacteriological cultures from pyoderma lesions revealed a single microorganism in the majority of the patients (84%). Staphylococcus aureus was isolated in pure culture from 48% and pure beta-hemolytic streptococci from 36%. A combination of both was obtained from 16%. No other organism was isolated from any case. A similar pattern was also observed in cultures from the nose and throat. Only 46 out of the 64 strains (84.3%) of Staphylococcus aureus isolated from pyoderma were typable. The majority (39.1%) showed a mixed pattern of phages; the second commonest was the non-allocated phage type (30.4%). Nasal flora had more of the non-allocated phage type (50%); two out of the three strains (66.6%) isolated from the throat showed a mixed pattern. All the strains of beta hemolytic streptococci, isolated either from lesions of pyoderma, nose, or throat belonged to group A. Staphylococcus aureus and showed a high sensitivity to netilmycin (100%), ofloxacin (98.4%), amoxycillin/clavulanic acid (96.9%), ciprofloxacin (89.1%) and gentamycin (84.4%) but a high resistance to penicillin (85.9%). A greater correlation was noted between nasal flora and organisms causing pyodermas. A change in the pattern of organisms causing pyodermas in children and their antibiotic sensitivities in this part of the globe has been observed in this study. The role of endogenous nasal and throat flora in the causation of pyodermas has also been highlighted.

A thirty-one year old male patient was diagnosed and treated for a pure or better primary neuritic case of leprosy with dapsone (100 mg daily for 2 years) and rifampicin (600 mg daily for 6 months). From the very outset, the patient did not show any improvement; on the top of it, he subsequently, developed a cutaneous patch, which on histopathological examination, revealed classical features of BT leprosy. Acid-fast bacilli were absent both in skin slit smear and histologic section. A primary resistance to both dapsone and rifampicin, even in paucibacillary patient, is speculated.

Nevus depigmentosus (ND) is classically defined as a congenital nonprogressive hypopigmented macule, stable in size and distribution. There have been many reports of colocalization of ND and lentigines. We describe development of multiple lentigines over ND in a 9-year-old girl along with hypoplasia of the underlying breast. The case is being reported to highlight the phenotypic manifestation of reverse mutation and the coincidental breast hypoplasia that has not been reported before.

Thirty five female patients with endocervicitis attending STD clinic were studied for the presence of Chlamydial infection by Polymerase Chain Reaction (PCR), Enzyme Immunoassay (EIA) and Cell Cytology. PCR was found to be positive in 54.2% of patients, Enzyme-Linked Immunosorbent Assay (ELISA) in 25.7% of patients, but cell cytology revealed the presence of inclusion bodies only in 3% of the cases, thereby showing that polymerase chain reaction is a better method for detection of Chlamydia trachomatis than EIA and cell cytology.

Twenty untreated patients of cutaneous tuberculosis varying from 2-12 years of age were included in the study. The incidence of cutaneous tuberculosis amongst the paediatric dermatological patients was 0.36%. Of these, 10 had lupus vulgaris, 8 had scrofuloderma, 3 had tuberculosis verrucosa cutis and 2 had lichen scrofulosorum. Three patients concomitantly had more than one type of skin tuberculosis. Systemic involvement in the form of pulmonary and osseous system was seen in 45% cases. The tuberculin test was uniformly positive. Affirmative clinico-histopathological correlation was observed in all the patients. However, acid fast bacilli could not be demonstrated in any of the sections. Only one patient (scrofuloderma) exhibited AFB on smear examination. In the same patient, M. tuberculosis could be cultured on L-J medium. However, Elisa for IgM antibodies in serum was positive in 12 (60%) cases. Need for newer techniques in the diagnosis is emphasised.
