Immunotherapy with Intralesional Candida Albicans Antigen in Resistant or Recurrent Warts: A Study

Background:

Warts are sometimes resistant or they tend to recur after every possible destructive therapy. Immunotherapy with skin-test antigens has been used as a viable therapeutic option in such recalcitrant cases.

Aim:

The aim of the study was to evaluate the response of resistant or recurrent warts to intralesional Candida albicans antigen immunotherapy.

Materials and Methods:

A total of 40 patients with resistant or recurrent warts who showed a positive test reaction to C. albicans antigen were given intralesional injections of purified C. albicans antigen solution in a single wart at 3-weekly intervals for a total of three doses. The patients were monitored for resolution of the injected wart as well as other untreated warts. The patients who responded positively were then followed up for any relapses over the next 6 months. Adverse events, if any, were also documented.

Results:

Of the 40 patients enrolled in the study, 34 completed the total treatment protocol of three injections and 6 months of follow-up. In these 34 patients, 19 (56%) showed a complete resolution of warts at all places on the body. In addition, two patients (6%) showed a partial or complete resolution of the treated wart, but there was no effect on the untreated warts. Thirteenpatients (38%) failed to show any response to the treatment regimen. In all patients showing resolution of all the warts, there were no relapses at any site over the next 6 months of follow-up. The most common adverse effect seen was pain during the intralesional injection.

Conclusions:

Intralesional Candida immunotherapy seems to be an effective treatment option in more than half of the patients who fail to show a positive response to destructive modes of treatment or in whom there are multiple recurrences.

Limitations:

The small sample size and lack of control group are the main limitations of the study.     

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.     

Autowart injection therapy for recalcitrant warts

Background:

Warts are caused by various strains of Human Papilloma Virus. They involve the epithelium of the skin and mucus membrane. Various treatment options are available, but extensive and recalcitrant warts not only cause distress to the patient cosmetically and psychologically but also pose a therapeutic challenge to the treating dermatologist.

Aim:

To evaluate the efficacy of autowart injection as a treatment option for extensive and recalcitrant warts.

Materials and Methods:

Autowart injection was prepared by removing 3 to 4 mm size wart with radiocautery which was crushed under aseptic condition and injected in the gluteal region by suspending in water for injection.

Result:

Results were evaluated in 53 available patients who turned up for follow-up; 35 patients (66.03%) had complete resolution in 2 months time, 12 patients (22.64%) showed partial improvement, whereas six patients (11.32%) had no improvement.

Conclusion:

Autowart injection is suggested as an effective and noninvasive therapeutic option in extensive and recalcitrant warts where most of the available therapies are inconvenient for both patient and treating dermatologist.     

Cutaneous manifestations of internal malignancy

Background:

Many malignancies affecting the internal organs display cutaneous manifestations which may be either specific (tumor metastases) or nonspecific lesions.

Aims:

The study is aimed at determining the frequency and significance of cutaneous manifestations among patients with internal malignancy.

Materials and Methods:

750 cases of proven internal malignancy, who attended a cancer chemotherapy center in South India, were studied. Specific infiltrates were confirmed by histopathology, fine needle aspiration cytology (FNAC) and marker studies.

Results:

Out of the 750 patients with internal malignancy, skin changes were seen in a total of 52 (6.93%) patients.

Conclusion:

Cutaneous metastases (specific lesions) were seen in 20 patients (2.66%): contiguous in 6 (0.8%), and non-contiguous in 14 (1.86%). Nonspecific skin changes were seen in 32 patients (4.26%). None of our patients presented with more than one type of skin lesions. Herpes zoster was the most common nonspecific lesion noticed in our patients, followed by generalized pruritus, multiple eruptive seborrheic keratoses, bullous disorder, erythroderma, flushing, purpura, pyoderma gangrenosum, insect bite allergy and lichenoid dermatitis.     

Utility of dermoscopy in alopecia areata

Background:

Alopecia areata (AA) shows several well-defined dermoscopic features which may help in confirming diagnosis in AA.

Aims:

We carried out a study to examine the dermoscopic features of AA and develop a protocol for diagnosis of AA by dermoscopy.

Materials and Methods:

Dermoscopy was performed in 66 patients with AA. Hanse HVS-500NP dermoscope (magnification of ×32 and ×140) was used.

Results:

The mean age of the patients (46 males and 20 females) was 26.85 years. The mean age of onset was 25.15 years. The mean duration of alopecia was 10.3 months. Most common AA in our study was patchy type (57/66, 87.7%). Single patch was seen in 24 patients and multiple patches in 33 patients. Diffuse AA was seen in five patients. Ophiasis and alopecia universalis were seen in two patients each. Nail changes were fine pitting (4), ridging (2), thinning of nail plate (2). Twenty nail dystrophy, distal onycholysis, striate leukonychia and coarse pitting were seen in one patient each. Intralesional triamcinolone acetonide was the most common therapy offered. Others were oral betamethasone minipulse therapy, dexamethasone pulse, minoxidil, anthralin and corticosteroids. The most common dermoscopic finding was yellow dots seen in 54 patients (81.8%), followed by black dots (44 patients, 66.6%), broken hairs (36 patients, 55.4%), short vellus hair (27 patients, 40.9%) and tapering hairs (8 patients, 12.1%).

Conclusions:

The most common dermoscopic finding of AA in our study was yellow dots, followed by black dots, broken hairs, short vellus hair and tapering hairs. Dermoscopic findings were not affected by the type of AA or the severity of the disease.     

Herpes zoster: a clinical study in 205 patients

Background:

Even though herpes zoster is a common condition its incidence and pattern of occurrence in the era of HIV disease is significant.

Aim:

To analyze the incidence, pattern of occurrence and evolution of herpes zoster with special attention to provocative factors if any.

Materials and Method:

This was an analytical study conducted for 2 years based on a preformed proforma containing preliminary information, a detailed clinical evaluation regarding the segment of involvement, morphology, pattern of lesions, complications, disseminations etc. and investigations to establish provocative factors if any.

Results:

Incidence of herpes zoster was mainly in the fourth and third decades of life. A definite history of chicken pox was present in only 63.4% cases. In the majority (70%) herpes zoster occurred spontaneously. In 30% cases, immunosuppression due to chemotherapy, malignancy, HIV infection, diabetes mellitus were observed. The commonest segment affected was thoracic (42.4%) followed by cranial (28.2%) and cervical (12.1%). Majority resolved in 7–14 days except immunosuppressed. 34.6% of the patients had complications such as secondary bacterial infection, post herpetic neuralgia, and motor weakness. Ten patients had HIV infection as a provocative factor.

Conclusion:

The results of incidence and clinical pattern of herpes zoster is almost parallel to the previous studies. Any factors of immunosuppression should be checked, especially HIV, particularly in disseminated and long-lasting cases.     

A Clinical and Mycological Study of Dermatophytic Infections

Background:

Dermatophytoses refer to superficial fungal infection of keratinized tissues caused by keratinophilic dermatophytes. According to observations worldwide, dermatophytoses are the most common of the superficial fungal infections. It is common in tropics and may present in epidemic proportions in areas with high rates of humidity. Although common, the precise size of the problem defies measurement.

Aims:

The present study was undertaken to assess the clinical profile of dermatophytic infection and to identify the species of fungi that are prevalent in this region.

Materials and Methods:

A total of 100 patients clinically suspected for dermatophytoses were selected for the study. Direct microscopy in 10% potassium hydroxide (KOH) and culture was done in each case.

Results:

Out of 100 patients, the maximum were seen in the age groups of 16-30 years. Tinea corporis was the most common clinical type (44.3%) followed by tinea cruris (38.2%). Overall positivity by culture was 39% and by direct microscopy 96%.

Conclusion:

Trichophyton rubrum was the predominant species isolated (67.5%) in all clinical types followed by Trichophyton mentagrophytes. Culturing the fungus may identify the species, but it is not essential for the diagnosis as it is not a sensitive test.     

CUTANEOUS MANIFESTATIONS IN PATIENTS SUSPECTED OF CHIKUNGUNYA DISEASE

Context:

An epidemic of chikungunya disease occurred in India during late 2005 through 2006 affecting nearly 1,400,000 people.

Aim:

To study the cutaneous manifestations in suspected cases of chikungunya disease.

Settings and Design:

Patients who attended our outpatient departments from January 2006 to September 2006 were prospectively included if they had symptoms of chikungunya disease according to the ‘case definition’ of the National Institute of Communicable Diseases, Directorate General of Health Services, Government of India. The criteria were an acute illness characterized by the sudden onset of fever and several symptoms such as joint pain, headache, backache, photophobia, and eruption during an epidemic of chikungunya fever in the absence of confirmatory serological tests.

Materials and Methods:

A total of 115 patients (65 men and 50 women) who satisfied the above criteria were enrolled for the study.

Results:

An erythematous maculopapular rash subsiding without any sequelae in 3-4 days was the most common cutaneous finding in our patients. Genital ulcers distributed predominantly over the scrotum and base of the penile shaft in men and labia majora in women were the second most common manifestation. Other manifestations included tenderness/edema of hands and feet, grouped hyperpigmented macules over the nose and cheeks, fixed drug eruptions, erythema nodosum, erythema multiformae, generalized urticarial eruptions, and flare up of pre-existing psoriasis and lichen planus.

Conclusions:

To conclude, a plethora of cutaneous manifestations were noted in suspected cases of chikungunya disease. Genital ulcers, to the best of our knowledge, have not been reported during the earlier epidemics but have been reported by others during the present one.     

Predominant Palmoplantar Lichen Planus: A Diagnostic Challenge

Background:

Palmoplantar lesions in lichen planus (LP) are uncommon. In such cases, diagnosis is usually missed. This study was conducted to document various clinical and histopathological features of palmoplantar LP.

Materials And Methods:

A total of 18 patients from our outpatient department with lesions of LP, either predominantly or exclusively on palms and/or soles were studied. Patients with history of drug intake in recent past and patients with classical acute widespread LP with a few lesions on palms or soles were excluded. In each patient, diagnosis was made on clinicopathological correlation. Various clinical and histopathological features were analyzed.

Results:

Average age of onset was 38 years. Male: female ratio was 1:0.6 and average disease duration was 11 months. Exclusive palm or sole involvement was seen in 4/18 patients. Itching was the most common symptom. Clinically the most common variant was hypertrophic. Histologically presence of parakeratosis, spongiosis, lack of melanophages, and lack of hypergranulosis in some cases was seen in addition to classical features of LP. In 3 out of 4 patients with exclusive palmoplantar involvement diagnosis of LP was missed clinically.

Conclusion:

Involvement of palms and soles in LP poses a diagnostic challenge due to variable presentations. Histopathology is of vital importance for correct diagnosis and treatment.     

Profile of Vitiligo in Kumaun Region of Uttarakhand,India

Background:

Vitiligo is a common, acquired, pigmentary disorder characterized by loss of melanocytes resulting in white spots. This disease carries a lot of social stigma in India.

Objective:

To study the clinico-epidemiological profile of vitiligo patients in Kumaun region of Uttarakhand state in India.

Materials and Methods:

The clinical presentation of vitiligo was examined and analyzed in 762 vitiligo patients attending the Dermatology outdoor of Government Medical College, Haldwani, which is a referral centre for Kumaun region of Uttarakhand state in India.

Results:

Male and female patients were found to be affected almost equally. It was observed that onset of vitiligo was most common in 0-10 years age group, as evidenced by 336 cases out of 762 cases. Acrofacial type of vitiligo (339 cases out of 762) was most commonly observed, followed by vitiligo vulgaris, focal, segmental, mucosal, mixed, and universal vitiligo. The most common site of onset was the lower limbs followed by head and neck, upper limbs, trunk, genitalia, and mucasae. Leucotrichia was observed in 33.5%, Koebner''s phenomenon in 26.3%, and a positive family history in 19% of the vitiligo patients. The other common conditions associated were thyroid disorders (8.9%), diabetes (5.3%), and atopic dermatitis (4.9%).

Conclusion:

The study indicates that acrofacial vitiligo is the most common clinical type observed in Kumaun region of Uttarakhand in India. Onset of vitiligo is most common in first decade of life.     

BENIGN AND MALIGNANT SKIN LESIONS IN RENAL TRANSPLANT RECIPIENTS

Background:

Skin lesions – benign and malignant – occur frequently in organ transplant recipients receiving long-term immunosuppressive therapy. These patients are at greater risk of skin cancers.

Aims:

To study dermatologic problems in renal transplant recipients (RTRs).

Methods:

One hundred patients (53 men and 47 women) were consecutively examined for benign and malignant skin complications since transplantation in Razi Hospital in Tehran Medical University. The main immunosuppressive therapy regimen in these patients was a combination of prednisolone, azathioprine, and cyclosporine.

Results:

The early and most common complication was cosmetic side effects that occurred in 98% patients. Skin infections occurred in 83% of the patients and most of them were viral infections (65%), especially of human papilloma viruses (HPVs) in 40% of the patients. We found six cases of malignancy in these patients in that four cases were skin cancers, including one case of SCC, one BCC, and two cases of Kaposi''s sarcoma. Dermatologic problems occur most frequently in RTRs, especially skin cancers which have higher frequency in these patients than general population, particularly, Kaposi sarcoma. Sun exposure has an important role in developing epithelial skin cancers following transplantation. The age of developing skin cancer in these patients was early than normal population.

Conclusion:

Our results emphasize the importance of dermatologic examinations and monitoring RTRs to obtain an early diagnosis and treatment of cutaneous manifestations.     

HIRSUTISM IN KASHMIR: AN ETIOLOGICAL STUDY

Background:

Hirsutism refers to the presence of terminal hairs at the body sites under androgenic control. Various factors, including genetic makeup and hormonal status, influence the rate and pattern of hair growth at these sites.

Purpose:

To study the pattern of hirsutism in Kashmir.

Materials and Methods:

Thirty five consecutive patients of hirsutism were included in the study. After detailed history taking, physical examination and relevant investigations, scoring of hirsutism was done using the Ferriman Gallwey (FG) scoring system.

Findings:

The FG score ranged from 10-34. Twenty patients had associated menstrual abnormalities. Polycystic ovarian syndrome (PCOS) was diagnosed in four patients, hypothyroidism in two and congenital adrenal hyperplasia (CAH) in one. The rest of the patients had idiopathic hirsutism.

Conclusion:

Idiopathic hirsutism was the most common category, whilst PCOS, hypothyroidism and CAH were also seen.     

Retrospective analysis of stevens-johnson syndrome and toxic epidermal necrolysis over a period of 10 years

Background:

Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), are the acute emergencies in dermatology practice. Prompt diagnosis and management may reduce the morbidity and mortality in SJS/TEN patients. Early identification of the offending drug is necessary for early withdrawal and to prevent the recurrences of such a devastating illness.

Aims

To study the demography, offending agents, clinical and laboratory features, treatment, complications, morbidity and mortality of SJS/TEN in our hospital.

Materials and Methods:

In this retrospective study, we reviewed the medical records of SJS, TEN, SJS/TEN overlap of inpatients over a period of 10 years

Results:

Maximum number of SJS/TEN cases were in the age group of 11-30 years. Males predominated in the SJS group with a ratio of 1.63:1, whereas females predominated the TEN group with a ratio of 1:2.57.Nonsteroidal anti-inflammatory drugs (NSAIDs) were the commonest group of drugs among the SJS group in 5/21 patients (23.8%). Antimicrobials were the commonest group of drugs causing TEN in 11/25 patients (44%). Mucosal lesions preceded the onset of skin lesions in nearly 50%. Our study had one patient each of SJS/TEN due to amlodipine and Phyllanthus amarus, an Indian herb. The most common morbidity noted in our study was due to ocular sequelae and sepsis leading to acute renal failure respectively. Kaposi''s varicelliform eruption was found in three of our patients.

Conclusion:

Antimicrobials and NSAIDS are the common offending agents of SJS/TEN in our study.     

Physical and psychosocial impact of acne in adult females

Background:

Acne, the most common problem that presents to dermatologists, can persist beyond teen years. Although its physical and psychosocial impact is studied in teen years, it is poorly understood in the Indian adult population.

Aim:

To study the physical and psychosocial impact of acne in adult females.

Settings and Design:

This exploratory study was done in the university setting.

Materials and Methods:

Eleven adult, unmarried females, between the age group of 18 and 25 years, having (mild-to-moderate), acne, for two consecutive years, were interviewed using a semi-structured clinical interview of the Skindex, a quality-of-life measure for patients with skin disease, developed by Chren et al., along with some open-ended questions. Both qualitative and quantitative analysis was done to analyze the data.

Results:

The results indicated a higher level of emotional and social impairment, in terms of the feelings of physical discomfort, anger, and the intermingling impact of these, among the participants.

Conclusions:

Acne is a common problem among adults and appears to have a considerable impact on the mental health, therefore, for the treatment to be successful, a sympathetic approach by doctors and significant others, with the basic psychosomatic treatment, are necessary.     

MUCOCUTANEOUS CHANGES IN TUBEROUS SCLEROSIS COMPLEX: A CLINICAL PROFILE OF 27 INDIAN PATIENTS

Background:

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disease resulting in a wide array of clinical manifestations, primarily affecting the skin and central nervous system. Mucocutaneous features play a very important role in the recognition of this syndrome.

Aims:

To review the prevalence and patterns of cutaneous manifestations in tuberous sclerosis, in a group of patients from eastern India.

Methods:

Observational clinical study on twenty-seven consecutive patients of tuberous sclerosis collected during a period of four years.

Results:

Most were between 10–20 years of age; the male to female ratio was 2:1. Family history was found in two-thirds. The classical triad of tuberous sclerosis was present in only nine (33.3%) patients. Adenoma sebaceum was the most common cutaneous feature (100%), followed by hypomelanotic macules (92.6%), connective tissue nevi (66.6%), and Koenen''s tumors (33.3%). Oral mucosal fibromas were seen in six (22.22%) patients. Fibromatous plaque over forehead and scalp was seen in three patients. Limitation of the study was small size of study sample.

Conclusion:

Prominent mucocutaneous changes are extremely common manifestation of TSC, which may provide crucial diagnostic clues for primary care physicians.     

Pilot study of sexual dysfunction in patients with psoriasis: influence of biologic therapy

Background:

Psoriasis is a chronic skin disease that affects 1 to 3% of the population in most industrialized countries. It is commonly associated with a variety of psychological problems including low self-esteem, depression, suicidal thoughts, and sexual dysfunction.

Materials and Methods:

We have performed a pilot study in which we have tried to assess the impact on sexual dysfunction in patients with psoriasis who have started treatment with biological therapy using validated indexes in Spanish: International Index of Erectile Function for men and female sexual function index in women.

Results:

Considering the men and women from our study, an improvement in FSFI by an average of 9.5 and 6.3 points is observed, respectively.

Conclusion:

We considered our series as a first step for a more detailed approach to the study of sexual function in patients with psoriasis.     

Melasma: a clinico-epidemiological study of 312 cases

Background:

Melasma is an acquired increased pigmentation of the skin, characterized by gray-brown symmetrical patches, mostly in the sun-exposed areas of the skin. The pathogenesis is unknown, but genetic or hormonal influences with UV radiation are important.

Aims:

Our present research aims to study the clinico-epidemiological pattern and the precipitating or provocation factors in melasma.

Materials and Methods:

A total of 312 patients were enrolled for the study over a period of one year.

Results:

The mean age of patients with melasma was 33.45 years, ranging from 14 to 54 years. There was female preponderance with a female to male ratio of approximately 4 : 1. The mean age of onset was 29.99 years, with the youngest and oldest being 11 and 49 years, respectively. The patients sought medical treatment on an average of 3.59 years after appearance of melasma. About 55.12% of our patients reported that their disease exacerbated during sun exposure. Among 250 female patients, 56 reported pregnancy and 46 reported oral contraceptive as the precipitating factors. Only 34 patients had given history of exacerbation of melasma during pregnancy. A positive family history of melasma was observed in 104 (33.33%) patients. Centrofacial was the most common pattern (55.44%) observed in the present study. Wood light examination showed the dermal type being the most common in 54.48% and epidermal and mixed were seen in 21.47% and 24.03% of the cases, respectively. We tried to find an association with endocrinal diseases and observed that 20 of them had hypothyroidism.

Conclusion:

The exact cause of melasma is unknown. However, many factors have been implicated in the etiopathogenesis of this disorder. Here we try to identify the causative factors and provocation to develop melasma.     

A clinical study of dermatoses in diabetes to establish its markers

Background:

Cutaneous manifestations of diabetes mellitus generally appear subsequent to the development of the disease, but they may be the first presenting signs and in some cases they may precede the primary disease manifestation by many years.

Aims:

The aim of our study was to study the spectrum of dermatoses in diabetics, to know the frequency of dermatoses specific to diabetes mellitus (DM), and to establish the mucocutaneous markers of DM.

Material and Methods:

The study was conducted at a diabetic clinic and our department between September 2008 and June 2010. Two hundred and twenty-four diabetic patients were included in the study group and those with gestational diabetes were excluded. Healthy age- and sex-matched individuals were taken as controls.

Results:

The male to female ratio was 1 : 1.21. Type 2 DM was seen in 89.7% and type 1 DM in 10.3% of the patients. Dermatoses were seen in 88.3% of the diabetics compared to 36% in non-diabetic controls (P<0.05). Cutaneous infections were the most common dermatoses followed by acanthosis nigricans and xerosis in diabetics. Type 2 DM was found to have an increased risk of complications than type 1 DM. Complications of diabetes were seen in 43.7% of the diabetic cases. Diabetic dermopathy, loss of hair over the legs, diabetic foot ulcer, and so on, were found to be the cutaneous markers of DM in our group of cases.

Conclusion:

Dermatoses were more common in diabetics than non-diabetics. Cutaneous infections formed the largest group of dermatoses in DM.
