Abstract

ABSTRACT:BACKGROUND:Antiandrogens have been developed to treat acne; spironolactone, an androgen receptor blocker, and finasteride, 5 alpha reductase inhibitor, are two antiandrogens that can be used to treat acne vulgaris.OBJECTIVES:To evaluate the effectiveness and safety of spironolactone , finasteride, and combination of both drugs in the treatment of acne vulgaris.PATIENTS&METHODS:This single blinded uncontrolled clinical therapeutic trial was done in the Department of Dermatology and Venereology – Baghdad Teaching Hospital- in a period from December 2004 to October 2006.The patients were classified according to the number of inflammatory lesions as having mild, moderate and severe acne. Severe acne was excluded from the study. History & close examination were performed to all patients regarding all points related to the disease. Sixty-nine patients with acne were divided into three groups and were instructed to take the following drugs for two months; group A: spironolactone 100 mg/day, group B: finasteride 5 mg/day, and group C: combination of both drugs.The clinical assessment was done by counting the number of inflammatory lesions every two weeks for two months, recording any local or systemic side effects, & comparison between the number of inflammatory lesions before and after treatment was done.RESULTS:Sixty patients had completed this work, whose mean± SD of their ages of the three groups totally was 18.8 ± 2.3 years and for group A, group B, and group C as follow : 19 ± 2.6, 19.3 ± 1.9, and 18.1 ± 2.4 respectively, with 20 patients in each group.Spironolactone was statistically significant in reducing the number of inflammatory lesions, finasteride was beneficial but did not reach a statistically significant level as spironolactone, and combination of both drugs was more effective in the treatment of acne vulgaris than spironolactone alone but did not reach a statistically significant level.CONCLUSION:Spironolactone is a good alternative drug to be used in patients with acne singly or in combination therapy with finasteride.

Abstract

ABSTRACT:BACKGROUND:Xeroderma pigmentosa although it is autosomal recessive disease but it is not uncommon problem in a certain regions in Iraq. It is always associated with well known complications of the disease like malignancies and blindness. Zinc sulfate has been successfully used in treatment of basal cell carcinoma in a form of intralesional injection & topical solution.OBJECTIVE:To evaluate the effectiveness of topical 20% zinc sulfate solution as a therapeutic and prophylactic agent in patients with xeroderma pigmentosa.METHODS:This single blind therapeutic trial was done in the Department of Dermatology & Venereology-Baghdad Teaching Hospital during the period from April 2004 to April 2005. Nineteen patients with typical features of xeroderma pigmentosa enrolled in this work. Full history and clinical examination were done for each patient regarding all points related to the disease. They were treated with topical 20% topical zinc sulfate solution and follow up was carried out for 4 months to 2 years.RESULTS:Nineteen patients with xeroderma pigmentosa were evaluated after treated with 20% topical zinc sulfate solution. Four patients were defaulted during follow up for unknown reason. The remaining were 15 patients (11 males and 4 females). Their ages ranged from 4-50 years with a mean± SD of 18 ±17 years. Monthly follow up showed improvement in all types of skin lesions including softening and lightening of the skin color, and clearance of solar keratosis and small malignancies. These were observed in the early course of therapy.CONCLUSION:This study showed that topical therapy with zinc sulfate solution had both therapeutic and prophylactic role in patients with xeroderma pigmentosa .We think that zinc sulfate is going to have a major role in management of this disease.

Abstract

ABSTRACT:BACKGROUND:Angiolymphoid hyperplasia with eosinophilia (ALHE) (pseudopyogenic granuloma) is a benign locally proliferating lesion composed of vascular channels with a surrounding infiltrate of lymphocytes and eosinophils.OBJECTIVE:ALHE is a rare disease but in Iraq it apparently seems to be more common than expected, for this reason the present work was arranged to evaluate the clinical and histopathological aspects of the disease.METHODS:This case descriptive study was conducted in the Department of Dermatology & Venereology- Baghdad Teaching Hospital during the period between June 1982- March 2005. Sixteen patients with this skin problem were included in this study. All demographic points related to the disease were obtained from each case through detailed history, close clinical and histopathological means.RESULTS:Sixteen patients with ALHE were evaluated. Their ages of patients ranged from 20-50 years with a mean ± SD of 35.73 ± 8.72 years, they were 14 females and two males. The duration of the disease ranged from 1-15 (6.4 ± 4.42) years.The clinical picture consisted of multiple dull to pinkish red angiomatous papules and nodules affecting the head only mostly around the scalp and ears. The histopathological examination revealed a proliferation & ectasia of blood vessels with eosinophilic infiltrate of the dermis.CONCLUSION:This study revealed that angiolymphoid hyperplasia with eosinophilia (ALHE) in Iraq, is a disease predominantly of adult females only affecting the head, with no lymphadenopathy and typical histopathology without lymphoid follicle formation. This is the first report describing this disease in Iraq and seems to be more common than European countries.

Abstract

ABSTRACT: BACKGROUND: Psoriasis is a common chronic condition of the skin that is resistant to many therapies. There is a need for the development of novel non-steroidal topical drugs for the treatment of psoriasis.OBJECTIVE: To assess the efficacy and safety of topical podophyllin 5% ointment in patients with mild plaque-type psoriasis.PATIENTS AND METHODS: Sixty two patients with mild plaque-type psoriasis were enrolled in this study. They were dividedinto 3 groups: GroupA (21patients)were treated with podophyllin 5% ointment every other day,while Group B(20patients)were treated with clobetasol propionate 0.05%ointment twice daily and21 patients in Group C were treated with Vaseline twice daily for 8 weeks as a control group.Efficacy was evaluated every 2 weeks for 8weeks using Psoriasis Area and Severity Index (PASI)score and relapse was recorded after cessation of treatment in those patients who achieved goodresponse during 8 weeks follow up period.RESULTS: A total of 62patients were 44(70.9%) males and 18(29.0%) females, with: male: female ratio 2.3:1.Their ages ranged from 18-65 (37.5±12.9) years. Their baseline PASI score ranged from 1.29(5.2±2.4).Attheendof8weeksoftherapy:nostatisticallysignificantdifferenceinPASIreductionbetweenGroupA(66.3±20.7) and Group B(68.1±34.2) treated patients, P-value =0.831 and both of themwere statistically significant higher PASI reduction than patients with Group C,34.1±28.8, P-value=<0.001.Regarding the percentage of patients who achieved good response, there was nostatistically significant difference between Group Aand Group B, 95.3% versus 70% ( Pvalue=0.083)and both of them achieved a statistically significant higher percentage of patientswith good response than Group C,47.6%, P-value=<0.001. Although the percentage of patientswith complete clearance (PASI≥90%) in the Group Awas much less, 9.5%, than that of Group B,65% (statistically significant, P-value=< 0.001), the total relapse rate during 8 weeks follow up wasmuch lower among Group Apatients, 25% versus 70%, P-value=0.043.On the other hand nocomplete clearance was achieved in the Group Cand their relapse rate was 80%.Regarding side effects: Group A, 9.5% of patients developed hypopigmentation, Group B, 10% ofpatients developed pyoderma and Group C, no side effects were reported. There was no statisticallysignificant difference among the three groups regarding the frequency of side effects (P = 0.355).CONCLUSION: Podophyllin 5% ointment on every other day regimen was as effective as clobetasole 0.05%ointment twice daily at the end of 8 weeks treatment with no side effects and with a much lowerrelapse rate.

Abstract

There are many risk factors that accentuate wrinkling like age, sex, occupation. Smoking is a preventable risk factor of facial wrinkles formation. To test the assumption whether skin wrinkling is significantly associated with age, sex and smoking or not? A cross-sectional study was conducted in Department of Dermatology and Venereology in Baghdad teaching hospital in period from April 2011 through March 2012 on (106) respondents, Socio-demographic information and full dermatological examination was done. Facial wrinkles were examined and measured according to wrinkles score in the group. Then we simplify these score into: superficial, (I, II), medium (III, IV) and deep wrinkles (V, VI). Smoking habit was more frequent in males than females which was ststistically highly significant (P=0.001). Middle and deep wrinkles are more frequent among males while shallow wrinkles are more among females which was highly significant (P<0.001). Shallow wrinkles only appeared in second and third decades of life while middle and deep wrinkles been more frequent in forth decade of life and above which also highly significant (P<0.001). Shallow wrinkles are mostly among non smokers while middle and deep wrinkles more among smokers and ex-smokers (P<0.001). The present work had confirmed a positive association between wrinkling score and the frequency of smoking habit.

Abstract

Background: There are many risk factors that accentuate wrinkling like age, sex, occupation and smoking. Clinically, there is some sort of relationship between facial wrinkling and skin malignancy in association with sun exposure. Objective: To test the assumption whether skin cancer has relation with skin wrinkling frequency and sunlight exposure or not? Patients & Methods: A case-control study was conducted in Department of Dermatology and Venereology in Baghdad Teaching Hospital in the period from April 2011 through March 2012 on ( 57) patients with various skin tumors, and (79) respondents as a control group. Socio-demographic information, sunlight exposure duration measurement and full dermatological examination were done. Facial wrinkles were examined and measured according to wrinkle score in the group. Scores were simplified into: shallow (I, II), medium (III, IV) and deep wrinkles (V, VI). Results: The frequency of skin tumors were as follow; basal cell carcinoma (45.6%), squamous cell carcinoma (42.1%), and others (12.3%). Outdoor activity was more in patients with tumor, while about one third of control group only had outdoor activity (P<0.01). Shallow wrinkles are more frequent among indoor workers while there is no difference in frequency of medium and deep wrinkles among indoor and outdoor workers. Patients with superficial wrinkles more commonly affected with skin tumors than those with deep wrinkles. Conclusion: The present work had confirmed a negative association between the frequency of wrinkling score and skin tumors. Sunlight exposure had positive association with skin tumors, while outdoor activity may increase frequency of deeper skin wrinkling.

Abstract

ABSTRACT:BACKGROUND:Acne vulgaris(AV)is chronic inflammatory disease of pilosebaceous unit of young people. Patients with acne with or with out scarring might differ in regard to their immunological background from those free from acne.OBJECTIVES:To evaluate the problem of facial AV especially patients with scarring and to determine the frequency of associated skin diseases and to be compared with acne free control.METHODS:A cross sectional randomized controlled epidemiological study was conducted from Oct.2005-Oct. 2006.Three hundred students from Basra University; 132 (44%) males and 168 (56%) females were enrolled, their ages ranged from 18-25 (20.9±1.8) years. They were divided into: Group A those free from acne (98 individuals),Group B with non scarring facial AV (96 patients), and Group C with scarring facial AV (106 patients). History and examination were done for their acne, scarring acne and associated skin diseases. Allen and Smith grading system for AV were used, and a new invented multiparametric scoring system for scarring acne was applied.RESULTS:AV was in 98(73.24%) males and 104 (61.9%) females. Scarring was 54 (50.95%) males and 52 (49.05%) females. Greasy skin was the most common type among Group B 67 (69.8%) versus 39 (39.8%) among Group A(P=0.000029) and was more common among Group C 84(79.2%) (P=0.00000001).Family history of AV was nearly similar in A and B Groups 55(57.29%) and 56 (52.83%) respectively, while in Group A was 39 (39.79%). Family history of scarring acne was in 35(33.02 %) of Group C, 16 (16.66 %) of Group B, and 3 (3.1%) in Group A; (P=0.00000017). The age of onset was similar in A and B Groups between 15-16 years. Majority of patients in Group B had non inflammatory type or mild inflammatory (papular) 65 (67.8%) patients, most of case were mild and moderate 86 (89.58%) patients, while high percent in Group C had inflammatory type 95 (89.62%), and more than half of them had severe and very severe types upon grading 56 (52.8%). The aggravating factors were similar in A and B Groups with stress and hot weather being the leading aggravating factors. Squeezing and digging habit was in 53 (50%) in Group C versus 23 (23.95%) in Group B (P=0.00024). In most cases of scarring acne, scarring was mild and moderate 85 (80.19%), and the most common type scars was the flat hyperpigmented [50 (47.17%) and 66 (62.26%) respectively].The most common effect of scarring acne on psyche was mild discomfort and mild dysmorphophobia 75 (70.75%).Associated skin diseases were more common among Group A 31 (31. 63%) than among Group B 22 (22.91%) and least common among Group C 14 (13.20%) (P=0.0067) and they were mainly dermatitis and skin infections.CONCLUSION:AV might reflect the immunological status especially among patients with scarring. The frequency of skin diseases was much less among patients with scarring acne

Abstract

ABSTRACT:BACKGROUND:The meaningful association of androgenetic alopecia and coronary heart disease had been well documented, but few studies had been focused on the importance of lipid parameters in patients with androgenetic alopecia.OBJECTIVE:To investigate the lipid profile and its relation to female pattern alopecia.PATIENTS & METHODS:This is a case controlled study conducted at the Department of Dermatology & Venereology- Baghdad Teaching Hospital, between January 2001 and April 2002. Sixty female patients with androgenetic alopecia were enrolled in this work. From each patient a detailed history and full clinical examination were performed regarding all demographic points relative to the disease, grading of alopecia and measurement of serum lipoproteins was done. Female pattern alopecia was classified according to Sharquei’s classificationSixty age and weight matched females with normal hair status were considered as a control group. Measurement of serum lipoproteins also performed for them.RESULT:Sixty patients, their ages ranged between 20-60 years with mean + SD of 30.3 + 9.4 years. Twenty (33.3%) patients were having grade I, 20 (33.3%) patients grade II and another 20 (33.3%) patients grade III.. The mean levels of total serum cholesterol, triglycerides, low density lipoprotein and very low density lipoprotein in all patients and those with grade II and III separately were significantly higher when compared to the control group. On the other hand, the mean levels of high density lipoprotein in all patients and those with grade I and III separately were lower in comparison to the control.CONCLUSION:The atherogenic index or risk ratio was found to be significantly high in patients with female patteren alopecia and this goes parallel with the severity of baldness.

Abstract

ABSTRACT:BACKGROUND:Ventral Penile Papillae (VPP) are benign asymptomatic structures that are found on the skin of the ventral aspect of penile shaft of many adult males; yet, no frank record or description of them is found in the English medical literatures.OBJECTIVE:To hit light on the VPP, finds their frequency among circumcised Iraqi adult males, seeks about their associations with other skin conditions, and examines the histological picture.PATIENTS AND METHODS:Forty seven Iraqi circumcised adult males were included in this case descriptive ,comparative study which extended between July 2007-November 2007 was conducted in Department of Dermatology- Baghdad Teaching Hospital. All 47 persons were asked about sociodemographic aspects, medical and skin conditions. They were evaluated clinically regarding different clinical aspects. Statistical data were deduced. Biopsies were done for 8 papillae from 6 persons for histological assessment. Also, 50 circumcised children under the age of 10 years were examined for the presence of these papillae as a control group.RESULT:Forty seven males were enrolled the present work, their ages ranged from 14-59(29.72+10.57) years. Twenty five (53.2%) persons had VPP, while 22 (46.8%) subjects showed no papillae. Fifty circumcised children of ages ranged from 3.5-10(5.97+1.42)years, all were lacking the papillae. The papillae were asymptomatic. Shapes of papillae were distributed as follows: skin tag-like papillae were 53.93%, dome-shaped 40.44%, while wartlike in 5.61% of these papillae. Histology was normal apart from finding of dermal encapsulated structures which simulate mechanoreceptor nerve endings, so called Meissner’s corpuscles.CONCLUSION:All facts start as speculative thoughts as had been proved by the present study. Ventral penile papillae are normal anatomical and physiological structures that are present in only adult males while completely absent in children. So the age of onset lies during adulthood. The location, morphology, age of onset, and the histology of these papillae are very suggestive of their sexual stimulatory function. Still further physiological and histological studies are strongly recommended.
