The topical treatment of anthroponotic cutaneous leishmaniasis with the tincture of thioxolone plus benzoxonium chloride (Thio-Ben) along with cryotherapy: a single-blind randomized clinical trial.

A simple efficacious topical treatment for cutaneous leishmaniasis (CL) is still an unresolved challenge. This study aimed to evaluate the efficacy of the topical use of thioxolone plus benzoxonium chloride (Thio-Ben) tincture in combination with cryotherapy in comparison with intralesional meglumine antimoniate (Glucantime) along with cryotherapy in treating anthroponotic CL (ACL). The study was conducted in Leishmaniasis Center in Dadbin Health Care Clinic, Kerman, Iran. Sixty-four CL lesions were randomly assigned to receive Thio-Ben plus cryotherapy (TC) (n = 32) or Glucantime plus cryotherapy (GC) (n = 32). Thio-Ben was used topically every other day and Glucantime was used intralesionally once a week for a maximum of 3 months. In both study groups, cryotherapy was administered using liquid nitrogen once every 2 weeks. Of 64 recruited lesions, 47 lesions completed the study protocol. Twenty lesions (91%) in TC group and 23 lesions (92%) in GC group showed complete cure. TC group showed faster clinical response. Pain, hypersensitivity reaction, dizziness, and nausea were only seen in GC group. This study showed that the topical use of Thio-Ben combined with cryotherapy has a good efficacy in treating ACL with the benefit that Thio-Ben has more patient compliance and less side effects than intralesional Glucantime.

Quality of life in patients with cutaneous leishmaniasis.

BACKGROUND: Leishmaniasis is a zoonotic infection caused by a protozoa belonging to the genus Leishmania. Its clinical manifestations range from a self-healing cutaneous leishmaniasis (CL) to lethal visceral leishmaniasis. We aim to examine the quality of life of patients with CL in Kerman, Iran.  METHODS: In this cross-sectional study we evaluated 124 patients with CL. The Dermatology Life Quality Index (DLQI) questionnaire was used for measuring quality of life. Data on demographics and characteristics of the lesions also were collected. Mann-Whitney U-test and Kruskal-Wallis were used for data analyses. RESULTS: The mean DLQI score was 5.87 ± 5.96. We observed the highest effect in the symptoms and feelings domains; the lowest effect was seen in the treatment domain of the DLQI. There was no significant difference in DLQI scores between men and women. Patients with ulcerated lesions had lower quality of life (P < 0.05).  CONCLUSION: CL significantly affects the quality of life of patients. Further studies are suggested to examine the effect of its treatment on the quality of life in these patients.

Adverse effects of intralesional meglumine antimoniate and its influence on clinical laboratory parameters in the treatment of cutaneous leishmaniasis.

OBJECTIVES: Intralesional injection of pentavalent antimoniate is recommended by the World Health Organization for the treatment of cutaneous leishmaniasis (CL). This study aimed to evaluate the adverse effects of intralesional injection of meglumine antimoniate (Glucantime(®) ) and its influence on clinical laboratory parameters. METHODS: A total of 105 patients with suspected lesions and therapeutic features of CL diagnosed by direct smear or skin biopsy were included in this study. Intralesional injection of Glucantime(®) was administered to treat CL. Fifty-five of the 105 patients were checked for hematological features, liver and kidney function, and fasting blood sugar levels before and after treatment. RESULTS: The observed side effects included pain (89.5%), burning sensation (81.9%), erythema (45.7%), pruritus (28.6%), secondary infection (17.1%), nausea (11.4%), vomiting (7.6%), urticaria (5.7%), necrosis (2.9%), sporotrichoid lesions (2.9%), dizziness (1.9%), dyspnea (1.9%), and anaphylactic shock (0.9%). No statistically significant differences were found in occurrences of adverse effects according to the part of the body affected, patient sex or age group, except for pruritus, which appeared more frequently in extremities than in other parts of the body (P < 0.001), and secondary infection, which was observed more frequently in people aged >45 years (P < 0.042). All clinical parameters remained normal after treatment. CONCLUSIONS: The occurrence of severe adverse reactions, particularly of anaphylactic shock, should be considered before treatment with Glucantime(®) is initiated. Thus, it is important that intralesional Glucantime(®) injections are administered in centers that are well equipped with appropriate resuscitation and support apparatus.

Cutaneous melanoma in a desert climate zone: a retrospective study of 125 cases.

BACKGROUND: With increasing incidence over the last few decades, cutaneous malignant melanoma (CM) represents 3% of all skin tumors, and accounts for 75% of all deaths because of cutaneous malignancies. Little is known about the nature and epidemiology of CM in individuals with pigmented skin. METHOD: Data were collected from the records of four public and private histopathology laboratories of Kerman city from March 20, 1994 to March 20, 2004. Skin biopsies with a diagnosis of CM were reevaluated to confirm the diagnosis of CM. The medical records of the patients were also taken into consideration. RESULTS: A total of 125 CMs were found. The male-to-female ratio was 1.08 : 1. The mean age at the time of diagnosis was 58.9 years; with a peak in the seventh decade of life. Acral-lentiginous melanoma (ALM) represented 28.8% and; nodular melanoma occurred in 20% of cases. Limbs were the site of occurrence in 44% of tumors; whereas 36% of tumors occurred in head and neck region. There was a significant correlation between age and ALM (P = 0.007) and also between gender and melanoma types (P = 0.024). CONCLUSIONS: This study indicates that some demographic and histopathologic features of CM in this population differ from those in the literature. More studies including cohort studies are needed to fully describe the nature and survival rate of CM in this area.

The relationship between infantile atopic dermatitis and urinary tract infection.

Atopic dermatitis (AD) is one of the most common infantile diseases. Immunological dysfunctions in AD patients may predispose them to infections. The aim of this study was to evaluate the relationship between infantile AD and urinary tract infection (UTI).In this cross sectional study, we enrolled 57 patients with AD aged 1 to 24 months that referred to dermatology clinic, and 57 healthy controls who were referred to pediatric clinic. The groups were matched according to age and gender. Urine samples were collected by clean-voided bag method. If a single organism was cultured at concentration of > or = 105 organisms per millimeter and the existence of white blood cells more than 10 per microscopic field was seen the patients underwent suprapubic aspiration. The presence of one organism in suprapubic aspiration sample was regarded as positive culture. Data were analyzed using SPSS version 15 software. P value <0.05 was considered as the level of significance. Twelve (21.1%) of AD patients and 1(1.8%) of normal controls had positive urine culture tests. The difference between two groups was statistically significant (p = 0.001). The most common bacteria was E-coli. Infants with AD showed a higher frequency of UTI in this study. So, we suggest screening all AD infants for urinary tract infection.

Determination of survival and hazard functions for pemphigus patients in Kerman, a southern province of Iran.

BACKGROUND: Pemphigus has in the past been associated with a high mortality rate. However, with the discovery of corticosteroids, patient median survival has improved. Our purpose was to assess median survival after confirmed diagnosis of pemphigus in patients in Kerman, a southern province of Iran. METHODS: All patients who were either admitted to the hospital or treated as outpatients in Kerman from 22 September 1987 to 22 September 1999 and who had confirmed pemphigus were included in the study. Survival was estimated using the Kaplan-Meier method, and the following variables were evaluated in a univariate analysis for an association with survival: age, sex, type of pemphigus, and type of therapy. RESULTS: A total of 55 patients (38 female and 17 male) were identified. No significant differences were found between genders. The mean age at the time of diagnosis was 46.0 years. Older groups had a lower survival rate than younger groups (P < 0.001). The majority (82%) of cases were vulgaris/vegetans, and no significant differences were found in 10-year survival for type of pemphigus (P > 0.05). The patients who had been treated with corticosteroids alone had longer median survival times than those who had been treated with corticosteroids plus azathioprine (P < 0.001). A total of 11 patients died; the median follow-up time for those still alive was 5.9 years (range 2-12 years). Estimated survival at 2, 6 and 10 years was 92.7, 86.8 and 61.5%, respectively. CONCLUSION: Overall median survival rate in patients with pemphigus was 10 years, regardless of gender or subtype of pemphigus. Survival was adversely affected by late onset. Those patients treated with immunosuppressives and corticosteroids also appeared to have reduced survival times when compared to those treated with corticosteroids alone.

The relationship between lichen planus and hepatitis C in dermatology outpatients in Kerman, Iran.

BACKGROUND: Lichen planus (LP) is classified as a papulosquamous disease. It has been associated with liver disease, particularly hepatitis C virus (HCV) infection, in several studies. Most of these reports, especially the larger series, were conducted in Europe and Japan. OBJECTIVE: We conducted a case-control study in Kerman, Iran to explore the association between LP and HCV. METHODS: The study included 66 patients with LP (as cases; mean age = 39.7 +/- 15.8 years; 31 female, 35 male) and 140 volunteer blood donors (as controls; mean age = 29.5 +/- 8.4 years; 43 females, 97 males). An enzyme-linked immunosorbent assay (ELISA) was used to determine the presence of anti-HCV antibodies in all subjects in both groups. To confirm positive diagnoses, a second generation recombinant immunoblot assay (RIBA II) test was performed. RESULTS: Lichen planus lesions were most frequently located on the trunk and extremities, and the most common clinical type was generalized LP (48.5%). One of the patients with LP (1.5%) and three of the controls (2.1%) were HCV-Ab positive. No significant difference was observed in HCV-Ab positive between the two groups (OR = 0.7; 95% CI = 0.1-6.9). CONCLUSION: The findings indicate that an investigation for HCV infection should not necessarily be performed in all patients with LP. It is recommended that further studies should focus on larger groups in other regions of Iran to determine whether testing for HCV infection is necessary in patients with LP.
