Profile of dermatology inpatients and admissions over a four year period in a tertiary level government teaching hospital in North India

Background: Although dermatology is mostly an outpatient specialty, some patients with severe skin disease need hospital admission for management. There is a paucity of data regarding the profile of these dermatology in-patient admissions. Aims: We studied the profile of patients admitted to the dermatology ward of our tertiary care government hospital in North India. Methods: This was a retrospective analysis of discharge sheets of patients admitted in the dermatology ward from January 1, 2014 to December 31, 2017. Results: Discharge sheets of 2032 admissions for 1664 patients were analyzed. The most common diagnoses in the admitted patients were immunobullous disorders (576, 28%), connective tissue diseases (409, 20%), infections, including leprosy and sexually transmitted infections (179, 8.8%), psoriasis (153, 7.5%) and reactive arthritis (92, 4.5%). The mean duration of admission was 13.95±11.67 days (range 1-118 days). Two hundred and fifty-six patients (15.38%) were re-admitted, accounting for 368 (18.11%) re-admissions. Patients with immunobullous disorders (OR 1.72, 95% CI 1.29-2.28) and psoriasis (OR 1.62, 95% CI 1.02-2.55) were more likely to be re-admitted. Adult patients, those who were admitted for more than four weeks, those who had comorbidities, and those who developed a complication during the hospital stay also had a greater likelihood of being re-admitted. Limitations: The retrospective design of the study, and the non-availability of data regarding transfers to other specialties or intensive care units and deaths were the main limitations of this study. Conclusion: This study describes the profile of patients admitted in a dermatology ward of a tertiary care centre center in North India. The patient profile and admission characteristics associated with a higher probability of re-admission were identified.

Prevalence of Hypertension in Children 10-18 Years of Age in Private Schools of Delhi and Their Associated Risk Factors.

Prevalence of non-communicable diseases were considered to be rare in children. But they have increased recently in developing countries, with increase in the prevalence of paediatric overweight and obesity. Body Mass Index (BMI) is commonly used to define overweight and obesity. Positive associations have been repeatedly reported between BMI and Hypertension.METHODSWe have conducted an observational cross sectional study of hypertension in 1250 students in the age group of 10-18 years studying in class 6 to 12 during school hours from July 2013 to June 2014. The values were recorded in multiples of 2 mmHg and levels greater than 95th percentile of age and gender were considered using the definition of the fourth report of NHBPEP. The association of risk factors were also evaluated.RESULTSOut of a total 1250 children, 239 (19.1%) had systolic hypertension, and 216 (17.3%) has diastolic hypertension. Prevalence of overweight and obesity were 11.8% and 7.5% respectively. Highly significant statistical association was found between body mass index (BMI) and both systolic and diastolic hypertension (p value 0.001).CONCLUSIONSPrevalence of both systolic and diastolic hypertensions were significantly high in overweight and obese children in comparison to normal weight children. Strong positive association was found between body mass index (BMI) and both systolic and diastolic hypertension. Association of other risk factors such as sex, family history, dietary habits like junk food intake and extra salt intake, were also observed

Relevance of trichoscopy in the differential diagnosis of alopecia: A cross‑sectional study from North India.

Background: Trichoscopy is an office tool used in the diagnosis of alopecia but its utility has not been assessed. Objectives: To compare the trichoscopic characteristics of different types of alopecia, identify features of diagnostic value, and to determine the utility of trichoscopy in the diagnosis of alopecia. Methods: A descriptive cross‑sectional study was performed in patients with alopecia. After clinical assessment and relevant investigations, trichoscopy was performed using a non‑polarized trichoscope (×10). The utility of trichoscopy in difficult cases of alopecia was assessed statistically. Results: One hundred and twenty patients of alopecia (90 non-cicatricial, 30 cicatricial) were recruited. The diagnosis was made on the basis of a detailed history and clinical examination, and confirmed by biopsy and relevant investigations in difficult cases. Yellow dots (63.3%) were the most common trichoscopic feature followed by thin hair (40.8%). Among the 21 difficult cases of alopecia, trichoscopy was diagnostic in 19 (90.5%). Statistically significant features on intergroup comparison included black dots (Fischer’s exact test, P < 0.001), cadaverized hair (P = 0.024), exclamation mark hair (P < 0.001) in alopecia areata; diameter diversity more than 20% (P < 0.001) and thin hair (P < 0.001) in androgenetic alopecia; broken hair of different lengths (P < 0.001), frayed hair (P < 0.001), split ends (P < 0.001) in trichotillomania; comma hair (P < 0.001) in tinea capitis and arborizing blood vessels in discoid lupus erythematosus (P = 0.012). Limitations: The small number of patients in some types of alopecia was a limiting factor. Conclusions: Trichoscopy is useful in the differential diagnosis of alopecia. Among the various trichoscopic findings, those of diagnostic value were identified.

Clinical effifi cacy of rituximab in the treatment of pemphigus: A retrospective study.

Background: Pulsed corticosteroids have been used successfully for the management of pemphigus. However, prolonged use of glucocorticoids may be associated with adverse effects and some patients show a poor response to conventional therapy. Biologics have shown a promising role in such cases; however, there is limited data from the Indian subcontinent. Objective: The primary objective was to assess the effi cacy and adverse effects of rituximab in pemphigus. The secondary objective was to measure the cumulative doses of corticosteroids required for these patients. Methods: We undertook a retrospective review of records of 25 pemphigus patients (pemphigus vulgaris: 21, pemphigus foliaceus: 4) who had received rituximab infusion (rheumatoid arthritis protocol in 21 patients, modifi ed in 4). Oral prednisolone was administered in dosages up to 0.5 mg/kg of body weight and tapered over the next 3–4 months according to the disease activity. However, other immunosuppressive agents such as cyclophosphamide and azathioprine were continued for one year after clinical remission was achieved. Results: Complete remission was observed in 22 (88%) patients. The mean time to disease control and complete remission was 1.10 and 4.36 months, respectively. Four (16%) patients experienced relapse after a mean duration of 11.75 months. The mean total dose of oral steroids administered was equivalent to 3535.64 mg of prednisolone. Exacerbation of disease was noted in two patients after the fi rst dose of rituximab and infectious complications, pneumonia and cellulitis, developed in one patient each. Limitations: A small sample size, the retrospective nature of the study and unavailability of follow-up anti-desmoglein autoantibodies levels were limitations. Conclusion: Rituximab is an effective agent in the treatment of pemphigus. The use of rituximab enabled use of a lower initial dose of oral prednisolone in pemphigus and hence reduced its total cumulative dose. Severe side effects were rare.

Nucleic acid amplification tests (NAATs) for gonorrhoea diagnosis in women: Experience of a tertiary care hospital in north India.

Background & objectives: Gonorrhoea is among the most frequent of the estimated bacterial sexually transmitted infections (STIs) and has significant health implications in women. The use of nucleic acid amplification tests (NAATs) has been shown to provide enhanced diagnosis of gonorrhoea in female patients. However, it is recommended that an on-going assessment of the test assays should be performed to check for any probable sequence variation occurring in the targeted region. In this study, an in-house PCR targeting opa-gene of Neisseria gonorrhoeae was used in conjunction with 16S ribosomal PCR to determine the presence of gonorrhoea in female patients attending the tertiary care hospitals. Methods: Endocervical samples collected from 250 female patients with complaints of vaginal or cervical discharge or pain in lower abdomen were tested using opa and 16S ribosomal assay. The samples were also processed by conventional methods. Results: Of the 250 female patients included in the study, only one was positive by conventional methods (microscopy and culture) whereas 17 patients were found to be positive based on PCR results. Interpretation & conclusions: The clinical sensitivity of conventional methods for the detection of N. gonorrhoeae in female patients was low. The gonococcal detection rates increased when molecular method was used giving 16 additional positives. Studies should be done to find out other gene targets that may be used in the screening assays to detect the presence of gonorrhoea.

A pilot study for diagnosis of genital Chlamydia trachomatis infections by polymerase chain reaction among symptomatic Indian women.

Background: Chlamydia trachomatis is the most common bacterial etiology of sexually transmitted infection. Aim : A pilot study was designed using PCR for amplification and detection of a specific 517 bp sequence of the common endogenous plasmid of C. trachomatis from clinical swab specimens obtained from symptomatic female patients attending STD clinics of AIIMS and Regional STD Teaching, Training & Research Center, Safdarjang Hospital, New Delhi. Methods: 97 patients were recruited in the study, and endocervical swabs were collected following standard procedures. The samples were analyzed by PCR and direct fluorescence antibody (DFA) for detection of C. trachomatis, and the sensitivity, specificity, PPV and NPV of PCR were calculated taking DFA as gold standard. Results: Out of 97 samples tested, 9 were positive for C. trachomatis by PCR. 1 PCR positive patient was negative by DFA although a total of 11 patients were positive by DFA. The sensitivity, specificity, PPV and NPV of PCR with reference to DFA was 72.73%, 98.84%, 88.89% and 96.59%, respectively. This PCR had high specificity and NPV for detection of C.trachomatis. Conclusions : In light of the introduction of enhanced syndromic approach, which involves the use of laboratory techniques (wherever possible) to confirm clinical diagnosis, a diagnostic PCR with high specificity and NPV is particularly valuable for determination of etiological diagnosis and hence contribute to judicious use of antimicrobials in the community.

Hydroxyurea as an alternative therapy for psoriasis.

BACKGROUND: Methotrexate is the drug of choice in extensive psoriasis in developing countries. In patients who can not take methotrexate either due to intolerance or concomitant liver disease, there is an urgent need for an alternative affordable and accessible drug. AIMS: To evaluate the therapeutic efficacy and safety of hydroxyurea as an alternative in the management of patients with extensive psoriasis. METHODS: A prospective study was carried out over 16 months on 34 patients with chronic plaque psoriasis (>20% body surface area involvement), erythrodermic or generalized pustular psoriasis who were partially responsive or non-responsive to the conventional topical and systemic modalities of therapy. Besides doing a baseline hemogram, liver and renal function tests, and urine analysis, these tests were frequently repeated during the course of therapy. Hydroxyurea was started at 1 g daily and increased to 1.5 g, if required. The therapeutic response was evaluated by a global assessment made by the patient and physician and regular PASI scoring. RESULTS: Good to excellent response was observed in 25 (73.5%) patients, less than 50% response in 7 (20.6%) patients, while 2 (5.9%) patients were lost to follow up. The mean PASI score was reduced by 76% at 10-12 weeks. Therapy was discontinued in 3 patients due to leukopenia that recovered on discontinuation of hydroxyurea. Patients were followed up to 1 year and relapse was observed in 5 patients. The duration of remission varied from 6 months to 1 year. CONCLUSION: Hydroxyurea is an effective and reasonably safe second line agent for psoriasis.

Atopy and alopecia areata in North Indians.

The study was undertaken with the aim of evaluating the effect of associated atopy on severity and age at onset of alopecia areata in north Indians. Presence of atopy was elicited by detailed history, examination and intracutaneous tests. Chi square test was carried out to evaluate statistical significance. One hundred patients (76 males and 24 females) with alopecia areata were evaluated. Historical evidence of atopy was present in 50 including patients alone (23), patients and first degree relatives (11) and first degree relatives alone (16). Intracutaneous tests were positive in 23 out of 50 patients tested randomly. There was a trend towards increasing frequency of severe alopecia as evidence of atopy became stronger e.g. both patient and first degree relatives with atopy or positive intracutaneous test but the results did not attain statistical significance. Similarly the age at onset and duration of alopecia areata was not significantly related to the presence of atopy. It is concluded that in north Indians with alopecia areata, the presence of atopy is not significantly associated with severe alopecia or onset at younger age.
