Aim: A comparative study for plaque removing efficacy between toothpaste, liquid handwashing soap, and two chemical-soak denture cleansers (clinsodent denture cleansing powder and fittydent denture cleansing tablet). Materials and Methods: A total of 140 healthy complete denture patients were selected and checked for denture cleansing using toothpaste, liquid handwashing soap, and two chemical denture cleansers: Clinsodent powder and fittydent tablets. Cleansing with plain water was kept as control for twenty patients. Results: The data were analyzed using Wilcoxon signed ranks test for checking the efficacy. The Kruskal--Wallis test was used for comparing the plaque removing efficacies of each denture cleanser used in the study. All four denture cleansers were significantly effective in removing plaque when compared with plain water, but there was no significant difference among them. Conclusions: There was no significant difference among action of four denture cleansers used in this study. Thus we can infer that patients can use liquid handwashing soap or commercial products to overcome disadvantages of toothpastes. Recommendation from the results of this study is the use of liquid handwashing soap for cleansing after every meal and soaking of the denture in commercial denture cleanser during the night.

Sexually transmitted diseases (STDs) in children are not uncommon in India, though systematic epidemiological studies to determine the exact prevalence are not available. STDs in children can be acquired via sexual route or, uncommonly, via non-sexual route such as accidental inoculation by a diseased individual. Neonatal infections are almost always acquired intrauterine or during delivery. Voluntary indulgence in sexual activity is also an important factor in acquisition of STDs in childhood. Sexual abuse and sex trafficking remain the important problems in India. Surveys indicate that nearly half of the children are sexually abused. Most at risk children are street-based, homeless or those living in or near brothels. Last two decades have shown an increase in the prevalence of STDs in children, though most of the data is from northern part of the country and from major hospitals. However, due to better availability of antenatal care to majority of women, cases of congenital syphilis have declined consistently over the past two-three decades. Other bacterial STDs are also on decline. On the other hand, viral STDs such as genital herpes and anogenital warts are increasing. This reflects trends of STDs in the adult population. Concomitant HIV infection is uncommon in children. Comprehensive sex education, stringent laws to prevent sex trafficking and child sexual abuse, and antenatal screening of all the women can reduce the prevalence of STDs in children.

Objectives: To conduct a cross-sectional study to compare Dsg1 and Dsg3 antibody levels independently with severity of disease activity in pemphigus vulgaris (PV) and pemphigus foliaceus (PF).Methods: Blood samples from 44 patients with pemphigus (PV-38, PF-6) were analyzed using ELISA. The severity of skin and mucosal disease was graded using a score from 0 to 3.Results: A statistically significant correlation between increase in Dsg 3 antibody titres with severity of oral involvement and Dsg 1 titres with severity of skin involvement was found in both PV and PF patients (p < 0.01). However, we were unable to demonstrate a relationship between increased titres of Dsg1 and Dsg 3 antibodies with oral and skin involvement respectively.Conclusion: This study suggests that the severity of skin and oral disease in pemphigus is determined by the quantities of Dsg1 and Dsg3 antibodies respectively.

Little information is available about the prevalence of skin conditions among children in the general population of northern India. Low socioeconomic status, malnutrition, overcrowding, and poor standards of hygiene are important factors accounting for the distribution of skin diseases in developing countries such as India. In order to estimate the burden and relative frequency of dermatologic diseases among children in the community, we measured the point prevalence of skin conditions in 12,586 Indian school children ages 6–14 years. The overall point prevalence of one or more identifiable/apparent skin conditions was 38.8%. Of those studied, 3786 children (30%) had only one skin disease, 765 (6%) had two, and 336 (2.7%) had three skin pathologies. The most common skin conditions and their respective point prevalences were skin infections (11.4%), pityriasis alba (8.4%), dermatitis/nonspecific eczemas (5.2%), infestations (5.0%), disorders of pigmentation (2.6%), keratinization disorders (mostly keratosis pilaris) (1.3%), and nevi/hamartomas (1.1%). This study shows that skin conditions are common in children and about one-third of them are affected at any given time. The finding that more than 85% of the disorders can be grouped into fewer than eight categories is important in designing training programs for medical teams involved in the delivery of primary health care services in developing countries such as India, where about one-third of the population is less than 15 years of age.

Abstract Background Melasma is a common disorder of facial hyperpigmentation. Many modalities of treatment are available, but none is satisfactory. Materials and methods Twenty-five nonpregnant female patients with a minimum melasma area and severity index (MASI) of 15 were recruited in the study. After a detailed history and clinical examination under natural light and Wood's light, MASI was calculated and color photographs were taken of all patients. Patients were advised to carry out a prepeel program of daily application of topical sunscreens (sun protection factor-15, SPF-15) and 10% glycolic acid lotion at night for 2 weeks. Patients were then treated with 50% glycolic acid facial peel once per month for three consecutive months. At regular intervals and at the end of the follow-up period (3 months) after the last peel, the degree of improvement in pigmentation was assessed by remeasuring MASI. Side-effects, if any, were also recorded. The data obtained were statistically analyzed using Student's paired t-test and Spearman rank correlation coefficient test. Results Improvement in melasma (reduction in MASI) was observed in 91% of patients (P < 0.01). Patients with epidermal-type melasma demonstrated a better response to treatment than those with mixed-type melasma (P < 0.05). Conclusions The prepeel program followed by 50% glycolic acid facial peel once per month for three consecutive months proved to be an effective treatment modality in Indian patients without any significant side-effects.

Aims We undertook this study to analyse the pattern of childhood cutaneous tuberculosis prevailing in northern India over the past 25 years and to highlight differences from and similarities to adult tuberculosis. Materials and methods Clinical records of children with cutaneous tuberculosis who attended the Nehru Hospital attached to the Postgraduate Institute of Medical Education and Research, Chandigarh, India, between January 1975 to December 1999 were analysed. Results Four hundred and two patients with cutaneous tuberculosis were examined during the 25-year period of observation. These patients formed 0.1% of the total dermatology outpatients. Seventy-five (18.7%) of these 402 cases were children (≤ 16 years). There were 32 (42.7%) boys and 43 (57.3%) girls with a boy: girl ratio of 0.74:1. The majority of the children, 41 (54.7%) were in the 10–14 years age group. There was no significant boy or girl preponderance in any group other than in scrofuloderma (SFD), where girls significantly outnumbered boys at all ages. Of the various patterns of cutaneous tuberculosis seen, 40 (53.3%) had SFD, 30 (40.0%) had lupus vulgaris (LV), 3 (4.0%) had tuberculosis verrucosa cutis (TVC), 1 (1.3%) child each had tuberculids and tubercular gumma. No child had a tubercular chancre or acute miliary cutaneous tuberculosis. The neck was the commonest site afflicted with SFD and the face was the commonest site affected with LV. No child had generalized lymphadenopathy. Eighteen (60.0%) of the 30 children with LV had regional lymphadenopathy of which 15 (83.3%) had Iocalized disease and 3 (16.7%) had disseminated disease. Of the 16 children with systemic organ involvement, 12 (75.0%) had regional lymphadenopathy. Of the 62 children in whom the data regarding vaccination status was available, 31 (50.0%) had been vaccinated and 31 (50.0%) had not. Among the vaccinated group no child had disseminated disease. Three (9.7%) children in the nonvaccinated group had dis... [ABSTRACT FROM AUTHOR]

Comments on a study conducted by N.L. Sharma et al. (1999) which gave an overview of reported cases of chromoblastomycosis in India between 1957 and 1997. Report on two additional cases in Chandigarh, India which occurred in 1991; Causative agents; Response of patients to itraconazole.

All new cases of alopecia areata (AA) were studied during the years 1983-1993. Eight hundred forty-one cases were recorded, including 201 (23.9%) children less than 16 years of age. The female:male ratio was 1.4:1 (117 girls, 84 boys) for childhood AA. Alopecia was severe, that is, total, universal, or extensive, in 34 (16.9%) children. Onset occurred in 77 (38.3%) children between ages 6 and 10 years, in 67 (33.3%) before 5 years of age, and in 57 (28.4%) between 11 and 16 years. Onset before 5 years of age was more often associated with severe alopecia than onset at ages 11 to 16 years (p < 0.01). Onset before 2 years of age was commonly associated with severe alopecia, seen in 6 (55.5%) of 11 children. Twenty-five (12.4%) children had one or more family members with AA. Definite evidence of atopy was obtained in 35 (17.5%) children. Association of atopy with severe alopecia was not statistically significant at initial presentation (16% vs 23.5% for circumscribed and severe alopecia, respectively; p > 0.05). Nail changes were found in 60 (30%) children and were more frequent in severe alopecia (53%) than in circumscribed alopecia (25.2%, p < 0.001). Associated vitiligo was found in seven (3.5%) children, and one child was hypothyroid. Childhood AA in Chandigarh, India, is remarkably similar to that seen in Western countries, except that an association of atopy with younger age at onset and severe alopecia was not confirmed.

During a period of eight years, 132 new leprosy cases were detected in children ages 3 to 19 years. Borderline tuberculoid leprosy was present in 59%, tuberculoid in 7.6%, and indeterminate type in 3.8% patients. Single skin lesions were seen in a significant number (43.9%) of patients. Bacillus-positive disease was detected more often (17.4%) than in adults. A high frequency (66.6%) of nerve involvement was also detected. Deformities were uncommon. Males were more often affected than females, especially in the ages 10 to 14 and 15 to 19 years. A history of contact was available in only 19.7% patients, and the contact was intrafamilial in 84.6%.

Background: Shortened (12 months) multidrug multibacillary regimen (MDT MBR) was implemented in India in 1998, however there is yet a paucity of crucial data on its long-term outcome., Objective: To assess the efficacy of 12 months MDT MBR in multibacillary (MB) patients at our centre., Design: This was a retrospective study undertaken analysing the clinic records of 1210 patients registered at the leprosy clinic of our institute from 1999 to 2010., Results: 730 MB patients were treated with 12 months MDT MBR over this period. High bacillary index (BI) > or = 3 + was observed in 313 patients at the time of registration. Four hundred and one (54.9%) patients experienced lepra reactions. Recurrent ENL was observed in only 14 patients which manifested even after 5 years of stopping treatment. Clinico-histological correlation was noted in 361 (49.5%) patients. During follow up period ranging from 9 months to 10 years, nearly all patients had clearance of skin lesions including histopathological/bacteriological improvement. Only 13 (1.7%) patients relapsed., Conclusions: All patients responded well with 12 months MDT MBR without significant side effects. The overall relapse rate was only 1.7%. Thus, the recommendation for 12 months MDT MBR for all MB patients is robust and operationally practical, a decision which seems logical.

Leprosy is among the world's oldest and most dreaded diseases and it has been synonymous with stigma and discrimination due to the hideous deformities it produced, mystery around its aetiology and transmission and lack of any effective remedy till recently. Leprosy control started with the use of chaulmoogra oil and for the last three decades, multi drug therapy (MDT) has been our main tool against leprosy. In the last two decades, the reported global prevalence of active leprosy infection has dropped by almost 90 per cent by the combined efforts of the World Health Organization (WHO), local governments, health professionals, and non-governmental organizations (NGOs), however, a parallel drop in the incidence or new case detection rate (NCDR) has not occurred. From 1994 through 2011, more than 100,000 new cases are being detected annually, of whom maximum case load is from India. There is need for research on tools for early diagnosis, short and effective treatment, and prevention of deformities and disabilities. Evaluating the role of immunotherapy and immunoprophylaxis will also lead us to better understanding of their mode of action. Further molecular analysis of Mycobacterium leprae genome may provide the requisite basis for all this. The current reality is that there is a need to sustain and provide quality leprosy services to all persons through general health services, including good referral system. All these provisions in the integrated health care approach will go a long way in further reducing the stigma. Efforts need to be made to reduce deformity through early detection, self care, physiotherapy and reconstructive surgery and developing sound surveillance systems. With all the remarkable achievements in the fight against leprosy, the stage is now set for the final assault. It is hoped that with the efforts of all the stake holders and strong political will, the disease will be eradicated in the near future.

Background: Atopic dermatitis is a chronic, relapsing disorder associated with significant morbidity. Growth retardation is known to occur in children affected with atopic dermatitis. However, there is not enough Indian data for this disorder., Aims: We conducted a longitudinal study to look for the effect of atopic dermatitis on growth attainment of Indian preschool children., Methods: The growth patterns of 62 children, aged 3-5 years and suffering from atopic dermatitis were studied in terms of body weight, height and head circumference. Sixty-eight normal healthy children matched for age, sex and socioeconomic status were taken as controls. Every child was followed up at intervals of three months following a mixed longitudinal study design for the duration of one year. Severity of the disease was determined by the scoring atopic dermatitis (SCORAD) index., Results: Growth velocities were lower in patients than in controls. Mean changes in body weight of patients of both sexes showed close similarity to controls. Mean values for height and head circumference were found to be significantly lower in girls than in the girls of the control group at majority of the age levels. In contrast, in boys, these values for the patients remained comparable or higher than in the boys of the control group at some of the ages. Girls had comparatively more severe disease than boys and they had lower values than boys for all the growth parameters assessed., Conclusion: Growth retardation was observed among children with a more severe form of the disease. Height of the affected children was compromised mostly, though a tendency for catch-up growth was observed. Severe forms of atopic dermatitis may impair a child's linear growth temporarily.

Background and Objectives: Though quinolones have been recommended as a single dose treatment for uncomplicated gonorrhoea, there have been reports of treatment failure with fluoroquinolones. In this study we determined the antimicrobial susceptibility levels of consecutive isolates of Neisseria gonorrhoeae to examine the emergence of ciprofloxacin resistance N. gonorrhoeae., Methods: Minimum inhibitory concentration (MIC) of ciprofloxacin and other drugs (penicillin, tetracycline, ciprofloxacin and ceftriaxone) was determined by agar dilution method. MIC was interpreted according to the NCCLS guidelines. beta lactamase production was detected by iodometric method and chromogenic cephalosporin method using nitrocefin disc., Results: A total of 45 consecutive isolates of N. gonorrhoeae were obtained from patients with suspected acute gonococcal uretheritis. Of the 45 isolates, 35 (77.7%) were resistant to ciprofloxacin, 16 (35.5%) showed MIC value greater than 8 microg/ml. All isolates were sensitive to ceftriaxone while 21 isolates (46.6%) were resistant to penicillin and 23 (51%) to tetracycline. Ten isolates (22%) were found to be beta-lactamase producers., Interpretation and Conclusion: Ciprofloxacin resistant N. gonorrhoeae is on the rise in and around Chandigarh (north India). Thus, periodic surveillance of susceptibility levels of N. gonorrhoeae is essential to prevent the dissemination of drug resistant strains in the community.

Background: Pure neuritic leprosy (PNL) constitutes a significant proportion of all cases in India, however, this form of disease has not been fully recognized and investigated and there is little information in the existing literature., Objective: To study the epidemiological characteristics of PNL in India., Materials and Methods: A retrospective analysis of leprosy clinic records for the period 1993 to 2003 was undertaken. Detailed demographic profiles and clinical findings were noted from the predesigned clinic proforma. A slit-skin smear for acid-fast baclli (AFB) was done in all cases from the area of sensory loss. A skin biopsy was done from the area of sensory impairment to study histopathological changes. Further investigations such as nerve conduction velocity studies (NCV), fine needle aspiration cytology (FNAC), or nerve biopsy (superficial nerve twigs) were done if indicated in patients whenever there was difficulty in clinical diagnosis., Results: Of the total 1542 leprosy patients seen over this period, 65 (4.2%) had PNL. Males were more commonly affected than females (2.6:1.). The majority of patients 40/65(61.5%) were aged between 15 and 35 yrs. Predominant presenting symptoms were paresthesia, pain, sensory/motor deficit, and trophic changes. A majority of the patients 39/65 (60.0%) presented with involvement of 2 or more nerves in the same extremity. Mononeuritis was seen in 26 (40%) patients. The nerves most often involved were the right ulnar nerve in the upper extremity, and the right common peroneal nerve in the lower limb. In general, the nerves of the upper extremity were more commonly involved than in the lower limbs (67 vs. 55). Motor deformities such as claw hand and foot drop were present in 13/75 (20%) and 7/65 (10.8%) patients, respectively. Slit-skin smears were negative in all patients, and skin histopathology from the area of sensory loss revealed non-specific inflammation in the dermis in a majority of patients, with perineural inflammation in a few. All patients were treated with multi-drug therapy (MDT); patients with >/=2 peripheral nerve trunk involvements were treated with WHO MDT MB regimen, while others were administered WHO MDT PB regimen. Follow-up for up to 2 yrs was available in only 32/65 (49.2%) patients, none of whom developed any skin lesions during this period., Conclusion: PNL is a distinct subset of disease frequently seen in India. There is need to pay more attention to this form of leprosy and diagnose and treat patients earlier to prevent deformities and sequelae of nerve damage.

Background: We undertook this study in order to determine the pattern and prevalence of childhood psoriasis in northern India and to highlight the differences and similarities with previous studies., Materials and Methods: In this retrospective epidemiologic study, the data from 419 children (less than 14 years of age) with psoriasis registered at the Psoriasis Clinic between January 1990 and December 2002 were included., Results: The 419 children registered at the Psoriasis Clinic constituted 0.3% of the dermatology outpatients and 12.5% of the total psoriasis patients seen over a period of 13 years in the department. There were 219 (52.2%) boys and 200 (47.7%) girls, with a male to female ratio of 1.09 : 1. The age of onset ranged from 4 days to 14 years. The mean age of onset was 8.1 +/- 2.1 years in boys and 9.3 +/- 2.3 years in girls. The peak age of onset in boys was in the 6-10-year age group, whereas the majority of girls showed an onset of psoriasis between the ages of 10 and 14 years. A positive family history was present in only 19 (4.5%) patients. The extensors of the legs were the most common initial site affected [105 (25%) cases], followed by the scalp [87 (20.7%)]. Classical plaque psoriasis was the most frequent clinical presentation [254 (60.6%) patients], followed by plantar psoriasis [54 (12.8%)]. Nail involvement was observed in 130 (31%) cases. All types of nail changes described in psoriasis were seen in these patients. Pitting was the most common nail change, followed by ridging and discoloration. Five children (1.1%) (three girls and two boys) had psoriatic arthropathy. Precipitating factors that brought about the onset of the disease or were associated with exacerbation could be recalled in only 28 (6.6%) patients. Koebnerization was observed in 27.9% of patients. Pruritus was the most frequent symptom, reported by 365 (87.1%) children. Twenty-seven (6.4%) children had other concurrent mucocutaneous diseases (vitiligo, pityriasis alba, alopecia areata, ichthyosis vulgaris, halo nevus, aphthous stomatitis, urticaria, pityriasis versicolor, nummular eczema, salmon patch, and verrucous epidermal nevus). Eighteen children had systemic disorders, including seizures, bronchial asthma, mitral regurgitation, scleroderma, Down's syndrome, high arched palate, cholelithiasis, anterior mongoloid slant, and prognathism; however, these conditions were possibly chance findings only and no correlation with the age of onset or severity of the disease was found., Conclusions: Our findings differ from those of previous studies in showing a delayed onset, equal sex distribution, less frequent facial involvement, uncommon guttate lesions, more frequent involvement of the soles, and a less frequent history of familial occurrence.

A retrospective analysis of patient's leprosy clinic records at PGIMER, Chandigarh, India for the period 1983 to 1998 was undertaken to study the frequency, time of onset, and risk factors for leprosy reactions. Of the 2600 cases analyzed, 1494 were multibacillary and 1106 had paucibacillary disease. Presentation with reaction was common with 30.9% of our patients having reactions at the time of first visit. The incidence of reversal reaction (RR) was highest during 6 to 12 months after starting multi-drug therapy (MDT), thereafter declining gradually. Late RR occurred in 9.5% of all cases and was noted up to 7 years after treatment. Female gender, widespread disease, and multibacillary disease were identified as risk factors for RR. Erythema nodosum leprosum (ENL) reactions were noted to occur mostly during second or third year after starting MDT. Of the total number of patients who experienced ENL, 64.3% had recurrent episodes which continued for up to 8 years after the start of treatment. Lepromatous leprosy, female gender, and high Bacterial Index (>/=3) were recognized as risk factors for developing ENL. Occurrence of recurrent and late reactions, even though of mild severity, highlights the importance of recognizing and treating them promptly to prevent or reduce morbidity, complications, and further deterioration in the disability status. Although it is hoped that leprosy will have been eliminated at all levels by 2005, the recognition and management of these reactions will continue to be the most essential/significant task in the post elimination era.

Three hundred leprosy patients were recruited to study the pattern and frequency of nail changes. Nail changes, like longitudinal ridging in finger nails, transverse striations involving both finger and toe nails etc. which occurred with similar frequency in the PB and MB patients in comparison with the control group, were excluded from the analysis. Out of a total number of 150 PB patients, 84 (56%) showed nail changes. Fifty-eight (38.6%) patients showed changes in the finger nails, with an average of 3.2 involved nails per patient. Fifty-three (35.3%) patients showed changes in the toe nails, with an average of 3.0 nails per patient. The most common change observed was longitudinal melanonychia (32.4%) in the finger nails and longitudinal ridging (46.3%) in the toe nails.In comparison, 131/150 (87.3%) MB patients showed nail changes. Finger nail changes were seen in 102 (68%) patients with an average of 5.5 nails affected per patient. Changes in toe nails were seen in 116 (77.3%) patients, with an average of 6.0 nails involved per patient. The most common nail change observed was longitudinal melanonychia in 89/523, (17%) of the total involved finger nails and subungual hyperkeratosis in 164/702, (23.4%) of the total toe nails involvement. Out of a total of 32 colony patients, 31 (96.9%) showed nail changes both in finger and toe nails with an average of 7.9 and 8.4 affected nails per patient, respectively. The most common nail change observed was rudimentary nail(s) on fingers (29%) and toes (21.1%). Among MB patients, a significantly higher number had finger nail involvement in LL group. The frequency of nail involvement for both fingers and toes was significantly greater in LL as compared to BL group of patients. The frequency of nail involvement was significantly more in patients having disease for more than 5 years and in those having trophic changes secondary to loss of sensations and impaired circulation.

Treatment of patients with severe psoriasis is difficult. Among the number of systemic drugs that are available, methotrexate has long been used, but cyclosporine has been recently recommended for the management of severe psoriasis. The purpose of this study was to compare the efficacy and safety of daily cyclosporine with weekly methotrexate in the management of severe psoriasis. Thirty consecutive patients with severe psoriasis were randomly assigned to treatment with cyclosporine or methotrexate. The initial dose of cyclosporine was 3 mg/kg/day, which was increased to a maximum of 4 mg/kg after two weeks of therapy when the response was not adequate. Methotrexate was administered weekly at a dose of 0.5 mg/kg. Clinical response was assessed by calculating PASI score in all patients at biweekly intervals. Patients were followed up fortnightly up to a maximum of 12 weeks. The doses of both drugs were gradually tapered once >75% reduction in disease severity was attained. Marked improvement (>75%) reduction in PASI was noted in all patients except for one in the cyclosporine group. The median time for marked improvement was 5.3 weeks with methotrexate and 6.8 weeks with cyclosporine. Patients on methotrexate were found to have more rapid and complete clearance than those on cyclosporine. Both drugs were well tolerated. Side effects in both the treatment groups were minor, transient, and manageable. At doses with comparable safety profiles, methotrexate resulted in more rapid and cost effective clearance of patients with severe psoriasis. Cyclosporine can provide an effective and safe alternative.

Background: The number of individuals diagnosed with diabetes mellitus is increasing worldwide. Although onychomycosis is often observed in diabetics, there have been no large studies of its epidemiology in this patient group in India., Methods: We studied the prevalence of onychomycosis in diabetics attending the Diabetes Clinic at the Postgraduate Institute of Medical Education and Research, Chandigarh, India, and compared it with that in a nondiabetic control group. A total of 400 diabetic subjects (237 males, 163 females), aged 48.8 +/- 0.5 years (mean +/- SD), were evaluated., Results: The prevalence of onychomycosis in the diabetic and control groups was 17% and 6.8%, respectively, the difference being statistically significant (P < 0.001). The presence of onychomycosis was found to correlate significantly with increasing age (P < 0.01) and male gender (P < 0.05) in both diabetic and control groups. From diabetics, yeasts were the most common isolate (48.1%), followed by dermatophytes and nondermatophyte molds in 37% and 14.8%, respectively. In the control group, the distribution of yeasts, dermatophytes, and nondermatophyte molds was 25%, 62.5%, and 12.5%, respectively. After controlling for age and sex, a stepwise logistic regression demonstrated that significant predictors for onychomycosis included the duration of diabetes (P < 0.01), absent or feeble peripheral pulses (P < 0.15), peripheral neuropathy (P < 0.05), and retinopathy (P < 0.001)., Conclusions: Diabetics were found to be 2.5 times more likely to have onychomycosis than the controls. Predisposing factors included increasing age, male gender, duration of diabetes, impaired peripheral circulation, peripheral neuropathy and retinopathy.

A total of 136 patients with BI > or = 2 having been followed up for at least 2 years or more were included in the analyses. Seventy-seven out of 136 patients had completed three years follow up. All patients were given WHO/MDT MB regimen for 12 months and additionally 4 doses of Mycobacterium w. vaccine at 3-month intervals. The age of the patients varied from 6 to 77 years (mean 34 +/- 11.3 years) and they had the disease varying from 3 months to 7 years (mean = 1.9 +/- 1.4 years). The mean of the BI before starting treatment was 3.6 +/- 1.3. At the end of 2 years follow-up, a total of 54 patients out of the 136 (39.7%) had become smear-negative. A larger proportion of patients, 39/46 (84.8%) with BI of < or = 3 had become smear-negative, whereas, only 10/32 (31.3%) patients with BI between 3.1 to 4 and 5/58 (8.6%) highly bacillated patients having initial BI > 4 had become smear-negative at the end of 2 years. Out of the 77 patients who were available for follow up at 3 years, 30/33 (90.9%) patients with BI of < or = 3, 15/20 (75%) patients with BI between 3.1 to 4 and 13/24 (54.2%) patients having initial BI > 4, respectively, had attained smear negativity. Reactions occurred more frequently after 6 months of therapy and over a period of time their frequency gradually decreased, however, they continued to occur even two years after RFT. During the course of MDT and thereafter in follow up 4.6% and 1.3% of the patients developed new deformities or an increase in the existing grade of deformities, respectively. Three relapses (2 in LL and 1 in BL) occurred in patients having initial BI of > 4. One patient relapsed in the second year and the other two relapsed in the third year of follow up and were successfully treated with reintroduction of the same MDT MB regimen. Local ulceration healing with scar formation and regional lymphadenopathy were the only local reactions to the vaccine seen in 47/136 (34.5%) patients. All the patients showed histopathological improvement in the form of a gradual reduction of granuloma fraction. Although the results of this limited period follow up are satisfactory, a long-term follow-up in larger number of patients will settle the issue of safety and efficacy of shortened MDT MB regimen and the place of immunotherapy with M. w. vaccine in multibacillary patients.

Genital herpes, which was considered to be a minor sexually transmitted disease (STD) in the past in developing countries, is rapidly increasing; in contrast, bacterial STDs are declining. This changing trend of various STDs prompted us to analyze our data retrospectively to see whether a similar change is occurring in this part of India as well. The records of sexually transmitted diseases (STDs) clinic attendees from January 1977 to December 2000 were analyzed. The demographic profile of patients with genital herpes was also considered for analysis. STDs were diagnosed clinically and by appropriate laboratory tests wherever applicable. VDRL test was done in all patients, and HIV antibody detection was performed from 1987 onwards. The incidences of chancroid, donovanosis, and gonorrhea were 12.2%, 6.3%, and 16.9%, respectively, from January 1977 to December 1985. The figures for the same decreased to 2.5%, 0.9%, and 2.3%, respectively, from January 1993 to December 2000. The decreasing incidence of the above bacterial STDs is statistically significant (p<0.001). However, there was an approximately two-fold increase in the incidence of genital herpes in recent years (20.5%) in comparison to the figures from the late 70s (11.4%). Molluscum contagiosum also showed an upward trend (1% in 1977-85 vs. 9.8% in 1993-2000). Condylomata accuminata remained almost unchanged (21.4% in 1977-85 vs. 20% in 1993-2000). To conclude, a significant increase in the number of viral STDs and a decline in the bacterial diseases were observed in recent years in comparison to the figures from the late 70s. This may be due to awareness of HIV, success of control programs, syndromic management of STDs, and adoption of safer sexual practices, which prevent bacterial STDs more efficiently than viral ones.

Although palmoplantar psoriasis can be severely disabling, there are very few large clinico-epidemiological studies on this condition. Our purpose was to study the morphology and pattern of lesions in Indian patients with palmoplantar psoriasis and to elucidate the role of occupation in the incidence/localization of these lesions. All patients attending our Psoriasis Clinic from 1993 to 2000 were screened for palmoplantar lesions and their demographic characteristics, occupation and the exact localization of the lesions were noted. Out of 3,065 patients screened, 532 had palm and/or sole involvement. Plantar lesions were seen in 91.9% and palmar lesions in 55.6% of these patients. Four distinct patterns of lesion localization were noted on the palms and 5 patterns on the soles. Almost half of the men involved in regular manual labor had palmar lesions restricted to areas exposed to pressure, whereas only a quarter of other men had this type of lesion pattern. All patients with unilateral palmar lesions had them on their dominant hand and these patients were involved in regular manual labor. In our patients, the prevalence of plantar lesions was much higher than that of palmar lesions. The possible role of occupational trauma in lesion localization in Indian patients with palmoplantar psoriasis is discussed.

A 57-year-old-male who had been a known case of psoriasis vulgaris for 30 years had a history of summer exacerbation of the disease. Subsequently in the course of the disease process, he developed lesions of chronic actinic dermatitis (CAD) on the face and dorsum of both hands. The association of CAD with photosensitive psoriasis is very rare. Only one case report is known till now. It may suggest that there is a relationship between the two diseases., (Copyright 2002 S.
