Cutaneous Mycobacterium fortuitum Infection: Successfully Treated with Amikacin and Ofloxacin Combination

Cutaneous infections caused by atypical mycobacteria are uncommon and the diagnosis can be missed unless there is strong clinical suspicion supported by laboratory confirmation. We report a case of chronic discharging sinus caused by Mycobacterium fortuitum in a young healthy immunocompetent individual. The patient recovered completely following amikacin and ofloxacin therapy.     

A Case of Fulminant Varicella Infection with Purpura Fulminans,Hepatitis, and Rhabdomyolysis

Varicella zoster virus causes varicella which is a common disease. Generally it is self-limiting, and treatment is often unnecessary, but severe or life-threatening complications are rarely seen. We report a case of fulminant varicella complicating with purpura fulminans, hepatitis, and probable rhabdomyolysis in a previously healthy child.     

Extensive Infection of Face by Mycobacterium chelonae: An Unusual Presentation

Mycobacterium chelonae is a rapidly growing mycobacteria, causes cutaneous, soft tissue, and rarely lung infections. Here we present a rare case of extensive infection of face at multiple sites by Mycobacterium chelonae, with an unusual presentation, diagnosed by using conventional methods.     

Apoptosis and Clinical Severity in Patients with Psoriasis and HCV Infection

Background:

It has been proposed that hepatitis C virus (HCV) antigens are involved in the pathogenesis of psoriasis and may contribute to severity of the disease. Increased expression of the apoptosis-regulating proteins p53 and tTG and decreased levels of bcl-2 in the keratinocytes of the skin of psoriatic patients have been reported.

Aim:

This study aims to identify the serum levels of apoptosis-regulating proteins in patients with psoriasis and without HCV infection and to study the relation between clinical severity of psoriasis and the presence of HCV infection.

Materials and Methods:

Disease severity was assessed by psoriasis area severity index score (PASI) of 90 patients with psoriasis grouped as mild (n = 30), moderate (n = 30) and severe (n = 30); 20 healthy individuals were used as controls. All groups were subjected for complete history taking, clinical examination, and tests for liver function and HCV infection. The serum levels of apoptosis related proteins: p53, tTG and bcl-2 were estimated by enzyme linked immune sorbent assay (ELISA).

Results:

There was a statistically significant (P < 0.001) correlation between clinical severity of psoriasis and presence of HCV antibodies and HCV-mRNA. In addition, significantly (P < 0.001) raised serum p53 and tTG, and reduced bcl-2 were observed among HCV-positive patients as compared to HCV-negative patients and control patients.

Conclusion:

These results conclude that clinical severity of psoriasis is affected by the presence of HCV antibodies and overexpression of apoptotic related proteins. In addition, altered serum levels of apoptosis-regulating proteins could be useful prognostic markers and therapeutic targets of psoriatic disease.     

Cutaneous Manifestations of Mixed Connective Tissue Disease: Study from a Tertiary Care Hospital in Eastern India

Context:

Mixed connective tissue disorder is an uncommon disease. Some scientists are reluctant to recognize it as a separate entity. Some others have defined this ailment. Cutaneous features of this condition are unique. Researchers from India have described these features to relate to those described in the studies from other parts of the globe.

Aims:

This study aims to delineate the skin manifestations of clearly defined mixed connective tissue disease (MCTD) patients, to compare them with those established as overlap syndrome, and to relate them with studies from other parts of the globe.

Settings and Design:

Successive patients who fulfilled the specific criteria for MCTD presenting in the skin outpatient department of a tertiary care hospital in eastern India were clinically examined from 2009 for 3 years.

Materials and Methods:

The number of participants was 23 and the dermatological features of these were compared with 22 patients with overlap syndrome. The antibody to uridine-rich U1 ribonucleoprotein was measured for all patients.

Statistical Analysis Used:

SPSS (Version 17) and MedCalc (Version 11.6).

Results:

The Male: Female ratio among the MCTD patients was 1:6.67 and that of the overlap syndrome was 1:10. Twenty patients of the MCTD group presented with synovitis as against only seven in the overlap group. Raynaud''s phenomenon was present in some of the subjects. Puffy fingers were rare in our study. Facial numbness was reported by four of those suffering from MCTD. Antinuclear antibody (ANA) was essentially of a speckled pattern in this disease

Conclusions:

Cutaneous indicators of MCTD are distinct from overlap syndrome. Knowledge of these manifestations prevalent in a region may lead to early diagnosis of the disease.     

Diffuse Cutaneous Mastocytosis with Bullous Lesions and Pulmonary Involvement: A Rare Case

Mastocytosis is defined as a heterogeneous group of disorders characterized by an accumulation of mast cells in one or more organs, particularly in the skin, bone marrow, liver, spleen and lymph nodes. However here we describe an 11-month-old girl child presented with diffuse cutaneous mastocytosis with bullous lesion, having pulmonary involvement, which is very rare and there is no available case report from India.     

Quality of Life and Psychological Morbidity in Vitiligo Patients: A Study in a Teaching Hospital from North-East India

Background:

Vitiligo is an acquired discoloration of skin and mucous membrane of great cosmetic importance affecting 1-4% of the world''s population. It causes disfiguration in all races, more so in dark-skinned people because of strong contrast. Men, women, and children with vitiligo face severe psychological and social disadvantage.

Aim:

To assess the impact of the disease on the quality of life of patients suffering from vitiligo, also to ascertain any psychological morbidity like depression associated with the disease and to compare the results with that of healthy control group.

Materials and Methods:

Dermatology Life Quality Index (DLQI) and Hamilton Depression Rating Scale (HAMD) are administered to 100 vitiligo patients presenting to the Dermatology OPD and 50 age- and sex-matched healthy controls. Results were analyzed and compared with that of control group. Findings are also correlated in relation to demographic and clinical profile of the disease. Statistical analysis is made to see the significance.

Results:

Vitiligo-affected patients had significantly elevated total DLQI scores (P < 0.001) compared to healthy controls. There is increase in parameters like itch, embarrassment, social and leisure activities in the patient cohort than the control group. Patients of vitiligo are also found to be more depressed (P < 0.001) than the controls.

Conclusion:

Quality of life (QOL) in patients affected with vitiligo declined more severely, and also there is increase in incidence of depression than in the control group. These changes are critical for the psychosocial life of the affected people.     

Portal Hypertension and an Atypical Reactive Arthritis Like Presentation in a patient infected with Hepatitis C Virus Genotype 3

Background:Reactive arthritis (ReA) is defined as a peripheral arthritis lasting longer than 1 month, associated with urethritis, cervicitis, or diarrhea. The reported annual incidence of ReA is approximately 30-40 cases per 100,000 adults, occurring commonly in the age group of 16 and 35 years. It is known to be associated with gastrointestinal infections with Shigella, Salmonella, and Campylobacter species and other microorganisms, as well as with genitourinary infections (especially with Chlamydia trachomatis).Conclusions:Our case is unlike classical ReA because the patient is older, HLA B27 negative, and without florid urethritis. Admitted for fever and lower urinary tract symptoms, along with respiratory distress, the primary objective of the emergency doctors was to prevent the patient from progressing to organ failure. The diagnosis of underlying atypical/incomplete ReA could easily have been missed without adequate awareness, dermatological consultation, and a skin biopsy.     

Clinical and Investigative Assessment of Patients with Positive Versus Negative Autologous Serum Skin Test: A Study of 80 South Indian Patients

Background:

Chronic urticaria (CU) is defined as urticaria persisting daily as or almost daily for more than 6 weeks and affecting 0.1% of the population. Mast cell degranulation and histamine release is of central importance in the pathogenesis of CU. About 40-50% of the patients with chronic idiopathic urticaria demonstrate an immediate wheal and flare response to intra-dermal injected autologous serum. This led to the concept of autoimmune urticaria.

Aims:

To determine the occurrence, clinical features, associated clinical conditions, comorbidities of autoimmune urticaria and to compare this with chronic spontaneous urticaria. This study aimed to find the frequency of autologous serum skin test (ASST) positive patients among patients with CU and to identify the clinical and laboratory parameters associated with positive ASST.

Materials and Methods:

Prospective correlation study was done on 80 chronic urticaria patients, more than 6 weeks duration, attending outpatient department of dermatology during a period of November 2007 to January 2010. Patients were subjected to ASST, complete blood count, urine routine examination, liver function tests, renal function tests, thyroid function tests, H. pylori antibody tests, C3 and C4 complement level estimation, antinuclear antibody, and urine analysis.

Results:

ASST was positive in 58.75% and negative in 41.25% of the patients, respectively. Out of 33 patients with history of angioedema, 9 (27.3%) patients were in ASST negative group and 24 were in positive group, this was statistically significant. Both groups showed no statistically significant difference for epidemiological details.

Conclusion:

ASST is considered a screening test for an autoimmune urticaria, which decreases the rate of diagnosis of “idiopathic” form of chronic urticaria. Patients with an autoimmune urticaria have more severe urticaria, more prolonged duration, more frequent attacks, and angioedema. Identification of autoimmune urticaria may permit the use of an immunotherapy in severe disease unresponsive to anti-histamine therapy.     

Role of Depression,Anxiety and Stress in Patients with Oral Lichen Planus: A Pilot Study

Context:

Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease.

Aims:

The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus.

Materials and Methods:

The psychometric evaluation using the Depression Anxiety Stress Scale (DASS)-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus) and group 2 (Control). DASS-42 questionnaire consists of 42 symptoms divided into three subscales of 14 items: Depression scale, anxiety scale, and stress scale.

Statistical Analysis Used:

The Student t test was used to determine statistical difference for both the groups and to evaluate for significant relationships among variables.

Results:

Psychological assessment using DASS-42 reveals lichen planus patients showed higher frequency of psychiatric co morbidities like depression, anxiety and stress compared to control group.

Conclusions:

This study has provided evidence that the DASS-42 questionnaire is internally consistent and valid measures of depression, anxiety, and stress. Psychiatric evaluation can be considered for patients with oral lichen planus with routine treatment protocols are recommended. DASS-42 Questionnaire can also be used to determine the level of anxiety, stress and depression in diseases of the oral mucosa like recurrent apthous stomatitis, burning mouth syndrome and TMD disorders.     

Pseudolymphomatous Folliculitis: A Distinctive Cutaneous Lymphoid Hyperplasia

Pseudolymphomatous folliculitis (PLF) was first described in 1986 as a distinct variant of pseudolymphoma, characterized by a dense lymphoid infiltrate and accompanied by hyperplastic hair follicles. Here in we report a case of PLF presenting as an erythematous plaque with pustules and satellite lesions on forehead in an otherwise healthy adult male patient.     

Clinical Profile of Leprosy Patients: A Prospective Study

Introduction:

Early diagnosis and early adequate drug treatment is very important aspect to reduce the load in cases of leprosy. So, correct labeling of paucibacillary and multibacillary cases is a prerequisite for the adequate treatment. Confirmation of diagnosis is an important indication for histopathological examination in doubtful cases.

Objectives:

The present study was carried out to know the clinical profile of leprosy patients, concordance between clinical and histopathological diagnosis in cases of leprosy, and to assess the therapeutic efficacy of antileprosy therapy.

Study Design:

Two hundred and fifty clinically diagnosed leprosy patients attending skin outdoor patient department (OPD) were included in the study. Slit skin smear was performed in all the cases. In that case concordance between clinical and histology can be determined only in 30 cases. All the patients were treated with MDT (multidrug therapy) as per WHO guideline.

Results:

A total of 250 patients attended the clinic with male to female ratio of 1.7:1. The highest incidence was noted in 17-40 years of age group. In the clinical disease spectrum, 40% patients were in the borderline spectrum followed by tuberculoid leprosy (TT) (29.2%), lepromatous leprosy (LL) (26.8%), and 3.9% of indeterminate leprosy (IL). A total of 18% of patients were of primary neuritic leprosy. A total of 8.3% patients had definite history of contact in the family or neighborhood. Clinicopathological correlation was noted in 60% of patients with maximum disparity (52.9%) in the borderline group of patients. A total of 52.8% were MB (Multibacillary) and 47.2% were PB (Paucibacillary) cases. Morphological index became negative after 6 months in all patients. Mean fall of bacteriological index after 6 months was 0.19, while after 1 year, it was 1.05.

Conclusion:

Timely diagnosis and adequate treatment of cases with MDT is most effective. Histopathological examination is must in doubtful cases of leprosy.     

A Clinicopathological Analysis of Primary Cutaneous Lymphomas: A 6-year Observational Study at a Tertiary Care Center of South India

Background:Little data are available concerning clinical and pathological patterns of cutaneous lymphomas in India.Aim:To analyze the clinical and histopathological characteristics of cutaneous lymphomas in Indian patientsResults:Among 35 cases, 33 (94.3%) were T-cell, and 2 (5.7%) were B-cell lymphomas. The mean age was 52.66, and the male to female ratio was 2.5:1. The most common types of T-cell lymphomas included mycosis fungoides (MF) (57.1%) followed by adult T-cell lymphoma/leukemia (ATL) (17.1%). Primary cutaneous peripheral T-cell lymphoma not otherwise specified was diagnosed in 17.1% and anaplastic large cell lymphoma in 2.9%. The morphological types of MF included polymorphic, poikilodermatous, folliculotropic, hypopigmented, hyperpigmented, mixed, and purpuric. Skin manifestations of ATL included ulcerated plaques and erythroderma. Epidermotropism was very marked in ATL (83.3%) than in MF (70%). Larger Pautrier''s microabscess was noted in ATL compared to smaller ones in MF. Markedly dense, diffuse infiltrate of atypical cells was noted in ATL in contrast to mild to moderate nodular or perivascular infiltrate in MF. ATL had an extremely poor prognosis.Limitations:Identification of DNA integration of HTLV-1 by Southern blot could not be analyzed, and the number of cases studied is limited.Conclusions:The study showed unique patterns of subtypes of cutaneous lymphomas in our country. Variations in the clinical pattern and histopathological analysis will help to differentiate T-cell lymphoma types which have prognostic implications.     

No Evidence of Human Papilloma Virus Infection in Basal Cell Carcinoma

Background:

Basal cell carcinoma (BCC) is the most common skin cancer among whites, and several risk factors have been discussed in itsdevelopment and progress. Detection of human papilloma virus (HPV) deoxyribonucleic acid (DNA) BCCs in some studies suggests that the virus may play a role in the pathogenesis of this disease. Several molecular studies showed conflicting reports.

Aims:

The purpose of this study was to investigate the association between HPV and BCC using polymerase chain reaction (PCR).

Materials and Methods:

HPV DNA detection was done for 42 paraffin-embedded tissue specimens of BCC and 42 normal skin samples around the lesions by PCR using GP5+/GP6+ primers.

Results:

HPV DNA was not found in any of the 42 samples of BCC, and only one normal skin sample around the lesions was positive for HPV DNA by PCR.

Conclusion:

In this study, no statistically significant difference was seen between the presence of HPV DNA in BCC and normal skin around the lesion, and HPV is not likely to have an important role in pathogenesis of BCC.     

Clinico-Mycological Study of Dermatophyte Toenail Onychomycosis in New Delhi,India

Introduction:

There is a constant need to define the epidemiological and mycological characteristics of onychomycosis (OM) for optimal management strategies.

Objectives:

To define the epidemiological and mycological characteristics of patients with dermatophyte toenail OM in a tertiary care hospital.

Materials and Methods:

Hundred consecutive patients of KOH and culture-positive dermatophyte toenail OM were subjected to detailed history, clinical examination and investigations.

Results:

Maximum number of patients (40%) belonged to 31-45 years age group and there was a male preponderance (M:F = 6.7:1). The mean duration of disease was 54 months. Thirty-three patients had fingernail involvement in addition to the toenail OM and 37% had co-existent cutaneous dermatophyte infection. Discoloration was the most common symptom (98%). Ninety-four (94%) patients had distal lateral subungual onychomycosis (DSLO) while two had superficial onychomycosis (SO) and only one had proximal superficial onychomycosis (PSO). Trichophyton interdigitale was the most common etiological agent (61%) followed by Trichophyton rubrum and Trichophyton verrucosum.

Conclusions:

Toenail OM is more common in males. DSLO was the most common clinical variant and T. interdigitale the most common etiological fungus responsible for toenail OM in our region. The importance of early diagnosis and treatment is highlighted as long-standing toenail OM predisposes to fingernail onychomycosis and recurrent tinea pedis.     

Cutaneous drug hypersensitivity: immunological and genetic perspective

Drug hypersensitivity is an unpredictable, immunologically mediated adverse reaction, clustered in a genetically predisposed individual. The role of "hapten concept" in immune sensitization has recently been contested by the "pharmacological interaction" hypothesis. After completion of the "human genome project" and with the availability of high-resolution genotyping, genetic susceptibility to hypersensitivity for certain drugs has been proved beyond doubt though the trend is ethnicity and phenotype dependent. Application of this newly acquired knowledge may reduce or abolish the morbidity and mortality associated with cutaneous drug hypersensitivity.     

Efficacy of Finasteride for Treating Patients with Androgenetic Alopecia who are Pileous in other Areas: A Pilot Study in Japan

Background:

Androgenetic alopecia (AGA) involves androgen-dependent hair loss and finasteride is an established treatment for the disease. However, reports of the influence of finasteride on hair growth in other areas of the body are lacking.

Aims:

To investigate the effects of finasteride on hair, including the head and other areas of the body.

Materials and Methods:

Based on whether AGA patients felt they were pileous in areas other than the head, they were divided into Group A (pileous) or Group B (not pileous). Finasteride (1 mg/day) was prescribed for both groups for at least 6 months, after which patients were asked to estimate the medicine''s effects and any changes of their hair growth.

Results and Conclusions:

A total of 18 out of 37 patients were placed in Group A and 19 of them were in Group B, suggesting that about half of AGA patients in Japan are pileous in other parts of the body. Oral finasteride was effective (excellent or good) in 22 out of 37 (59.5%) patients overall, in 16 out of 18 (88.9%) patients in Group A, and in 6 out of 19 (31.6%) patients in Group B. None of the patients reported that oral finasteride had any effect on their hair growth other than on their head. Finasteride is more effective for treating AGA patients who are pileous in other areas of the body.     

A META-ANALYSIS COMPARING EFFICACY OF CONTINUOUS TERBINAFINE WITH INTERMITTENT ITRACONAZOLE FOR TOENAIL ONYCHOMYCOSIS

Background:

Toenail onychomycosis is a challenge for clinicians to treat. While both Itraconazole and terbinafine have proven to be effective against onychomycosis, very little is known about their comparative efficacy in achieving mycological and clinical cure.

Aim:

The purpose of this meta-analysis is to compare the efficacy of continuous terbinafine with intermittent itraconazole in the treatment of toenail onychomycosis.

Material and Methods:

all RCTs comparing continuous terbinafine with intermittent itraconazole were identified from PUBMED and BIDS electronic database.

Results:

analysis of total eight trials including 1181 patients state that treatment with continuous terbinafine is more likely to produce mycological and clinical cure compared to intermittent itraconazole with odds ratio 2.3(95% CI, 1.7 to 3.0 P<0.0001)

Conclusion:

though both itraconazole and terbinafine are well tolerated and highly effective drugs, continuous terbinafine is more effective than intermittent itraconazole at achieving mycological cure of toenail onychomycosis     

Radiation Port Cutaneous Metastases: Reports of Two Patients Whose Recurrent Visceral Cancers Presented as Skin Lesions at the Site of Previous Radiation and Literature Review

Radiation therapy is associated with a variety of complications, including the development of primary skin cancers in the radiated region. However, it is rare for patients with visceral cancers who are treated with radiation therapy to subsequently develop cutaneous metastasis within the radiation port. We describe two patients with internal malignancies who developed cutaneous metastases within their radiation ports following radiotherapy. In addition, we used PubMed to perform an extensive literature review and identify additional reports of cutaneous metastasis within a radiation port. We excluded patients who developed melanoma or primary skin cancers in the radiation port. We also excluded patients with non-solid organ malignancies. Herein, we summarize the characteristics of 23 additional patients who experienced radiation port cutaneous metastases and explore possible mechanisms for the occurrence of radiation port cutaneous metastases.
