Importance: As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic spreads, increasing cases of dermatologic manifestations of the disease continue to be reported. Observations: In this general review of the case reports, case series, and other systematic reviews on this subject, several patterns of cutaneous lesions have been compiled. These include viral exanthems, papulovesicular, pernio-like, vasculopathy-related, and other miscellaneous rashes. Conclusions and Relevance: While clinical observations and subjective cases of rashes associated with SARS-CoV-2 are important to furthering our research and study of this viral disease, we as clinicians must be cautious in attributing causation with correlation. Continued research and study are needed before we can attribute a source for these dermatologic manifestations. Funding: This research was partially support by IMPACT funds to NY from the School of Medicine, University of Alabama at Birmingham.
Treatment of Recurrent Aphthous Stomatitis by Crude Topical Sesame Seed Oil in Comparison with Crude Topical Pumpkin Seed Oil
Background: Recurrent aphthous stomatitis (RAS) is the most common disease of the oral mucosa in the general population. Multifactorial etiopathogenesis has been suggested to explain the cause of RAS but the exact etiology and pathogenesis still unknown. Its therapy whether topical or systemic can induce clearance but the relapse rate is high. Objective: To evaluate the efficacy and prophylactic effects of topical Sesame seed oil in comparison with Pumpkin seed oil in the management of recurrent aphthous stomatitis. Patients and Methods: This is a single, blinded, clinical, therapeutic, comparative study where 35 patients with early onset RAS were examined in Center of Dermatology -Baghdad Teaching Hospital, Medical City ,Baghdad, Iraq from April 2018-October 2019. All socio-demographic data related to the disease was obtained from each patient, in addition to clinical examination was performed for each patient. Patients were divided into 2 groups: Group A (15 patients) used crude Sesame seed oil twice daily. Group B (20 patients) was instructed to use Pumpkin seed oil in a similar way to Group A. Short term assessment of each patient of both groups was done to evaluate the therapeutic effect of drug by using oral clinical manifestation index (OCMI). A long term assessment was done for each patient to assess the prophylactic effect of drug by using OCMI before, after 1, 2 and 3 months of therapy. They were seen regularly to record any local or systemic side effects. Results: The patients enrolled in this study were 19 (54.3%) males and 16(45.7%) females, male to female ratio was 1.1: 1. Their ages ranged from 12-60 (35.33 ± 12.06) years. The mean of OCMI in Group A started to decline directly after 4 days of therapy and went to its lower level after 8 days of therapy, and it was statistically significant (P value
Topical Therapy of Vitiligo Using Sunlight Exposure with Lactic Acid Cream (10%) Versus Methoxsalene Solution
Background Vitiligo is a common autoimmune disease to which multiple therapies have been used. Lactic acid in different modes of preparation like 15% topical solution and 1% intralesional injection has been tried effectively in treatment of vitiligo. Objectives to test the efficacy of lactic acid cream10% with sunlight exposure in treatment of vitiligo, and to be compared with topical methoxsalene solution with sunlight exposure. Materials and Methods This is an interventional, therapeutic, single blinded, comparative study that was conducted in the Center of Dermatology, Medical City, Baghdad, Iraq, between April 2018 and June 2019. Patients with generalized and localized vitiligo were included. The diagnosis of vitiligo was based on clinical characteristic loss of skin pigmentation and supported by woods light examination. The demographic features were recorded. Physical examination was done to determine the site and number of patches per patient. The patients were divided into two groups: group A patients, were treated with lactic acid 10% cream followed by sunlight exposure. While in group B, the patients were treated with topical methoxsalene solution followed by sunlight exposure. All patients were assessed, and the surface area of each patch was measured before starting the treatment and every month for 3 months of treatment. The side effects were also recorded. A follow up visit after 3 months was done. A reduction rate in the surface area of vitiliginous patch was calculated. Results sixty patients, 41 (68.3%) females and 19 (31. 7%) males with a female to male ratio was 2.15:1. Their ages ranged between 3 – 42 years with mean± SD of 23.36±11.95 years. The disease duration ranged between 12-120 months. Total number of the lesions was 78 patches with a mean of 1.3 lesions per patient. No statistically significant differences were found between the two groups regarding demographic nor clinical features…
Background: Follicular dermatoses are skin diseases that involved the hair follicle either early or during the course of the disease. Objective: To collect a number of dermatoses where there is follicular involvement, to be studied and analysed in order to reach a conclusion that hair follicles are the most important target area in the pathogenesis of these dermatoses. Patients and Methods: This is a descriptive, clinical and histopathological study that was carried out at the Centre of Dermatology and Venereology, Baghdad Teaching Hospital, Medical City, Baghdad, Iraq during the period from December 2017 to August 2019. Forty patients with follicular dermatoses were included and all socio- demographic data related to the disease was obtained from each patient, in addition to clinical examination was performed for each patient. Lesional biopsies were done for 20 patients, for histopathological examination by Haematoxylin and Eosin (H&E). Results: The mean age ± SD was 30.2±16.96 years, 25 patients were males and 15 patients were females, the clinical diagnosis of follicular diseases was established for all skin diseases included in the present work. The histopathological findings of lesional biopsies were mainly: perifollicular lymphocytes, follicular invasion and degeneration, follicular plugging, fibrous tract remnant, perifollicular melanophages and hair follicle cyst. Conclusion: The result of the present study does encourage us to suggest that almost all skin diseases included in this study start initially on the hair follicle and then spread to involve the adjacent epidermis.
Background: Prurigo nodularis (PN) is a well-defined chronic recognized entity as a cause of severe chronic itching. However, this medical problem is not well studied and evaluated previously in Iraqi population. Objective: To do full clinical and histopatholgical evaluation of patient with PN. Patients and methods: This study is an observational cross sectional that was conducted at the Center of Dermatology, Medical City Teaching Hospital. All cases with classical PN and localized variant where collected. Full clinical evaluation was carried out. Biopsies were taken from 10 patients out of 50 with prurigo nodularis processed and stained with Hematoxylin and Eosin. Results: Fifty patients were included, there were 22 (44%) males and 28 (56%) females ,their ages ranged from less than 20-60 years with mean ± SD of age (40 ± 16) years .The common associated disease was atopic dermatitis in 36 (72%) patients, while family history of disease was seen in 24 (48%) patients, psychological factor was seen in 30 (60%) patients . The clinical picture was excoriated nodular lesions commonly on limbs with symmetrical fashion in 40 (80%) of cases while localized pattern was detected in 10 (20%) of patients. Histopatholgical evaluation in ten patients had shown hyperkeratosis (100%), acanthosis (60%), and pseudoepithelamatous hyperplasia (40%). Eosinophils were seen in one patient. Conclusion: This study showed classical prurigo nodularis in 80% of cases while localized in 20% of the patients. It is a disease of middle age patients, more in females than males. Family and personal history of atopic dermatitis was a high finding the histopathology is typical of prurigo nodularis with sparse eosinophils.
Background: Scabies is one of the common epidemic and endemic diseases worldwide. Many topical therapeutic modalities for scabies are available. Topical ivermectin has been used effectively in treatment of scabies but there is no oral effective therapy that prevents contacts to get scabies. Objective: To evaluate the effectiveness of oral ivermectin in prevention of scabies contacts to get scabies. Patients and Methods: The study is a single-blinded therapeutic study that was conducted in the Center of Dermatology, Baghdad Teaching Hospital, Baghdad, Iraq during the period from April 2018 through October 2019.Two hundred sixty healthy scabies contacts were included in this study, their ages ranged from 5-60 years with a mean ± SD of 19.3± 1.9 years. All these contacts were screened for active scabies and they were all free. The contacts of scabies were treated by ivermectin tablet 200 microgram per kg as a single dose after 2 hours from dinner. They were seen regularly after 4 weeks to be re-examined and to record any scabies and drug side effects. Results: The response after four weeks of single dose therapy of healthy contacts showed that 245 (94%) from 260 were free of scabies and only 15(6%) contacts showed infection with scabies and this was statistically significant Chi-square (c2= 148, P-value less than 0.00000001. No any side effects were noticed in any treated contacts. Conclusion: Oral single ivermectin dose is an effective therapy to prevent scabies contacts to get infection. It an easy method of prevention which is very useful in condition of scabies outbreaks and epidemics to stop the rapid spread of the disease.
Background: Keratosis pilaris rubra (KPR) is a common but unrecognized follicular keratinizatioin. It is a common skin problem among Iraqi population and most cases were misdiagnosed as dermatitis as there are few reports in medical literature. Objective: To do full clinical and histopathological evaluation of KPR in Iraqi population. Patients and Methods: This is case descriptive, clinico-histopathological outpatient based study. It was done in the Center of Dermatology and Venereology, Baghdad Teaching Hospital, Medical City, Iraq during the period from March 2016 to October 2017. Sixty patients were enrolled in this study. History and dermatological examination were carried out for all patients. Skin biopsy was done for 10 patients for histopathological study using Hematoxylin and Eosin stain. Results: A total of the 60 patients were diagnosed as KPR during the study period. Thirty nine (65%) males and 21 (35%) females. The age at onset of disease ranged from since birth to 8 (2.9± 2.17) years . Facial involvement included the cheeks in 60 (100%) patients. Other sites of involvement included the arms where the lateral aspects involved in 60 (100%) patients and the medial aspect 11 (18.3%), thighs including the buttocks in 51 (85%), trunk 25 (41.6%), legs 22 (36.6%) and the neck 15 (25%).The rash was erythematous all over but most obvious on the sides of face presenting as red, rough face. Histopathological evaluation showed follicular plugging in (100%) with dilatation of both superficial and deep vascular plexus in (75%) of cases. Limitation: The main limitation of this study was the lack of follow up data related to the subject of the study. Conclusion: KPR is a common condition among Iraqi population and this study is the largest study carried out all over the world. As most areas of body are involved, the name keratosis pilaris rubra totalis is…
Background: Scabies is one of the commonest endemic pruritic diseases all over the worldwide. Many topical therapeutic options for scabies are available, but none of them could be accepted by many patients as all of them need covering the whole body by ointment overnight. Accordingly patients are looking for safe oral therapy like many other diseases. Objective: To assess the effectiveness of oral ivermectin in the treatment of scabies. Patients and Methods: This single, blinded, therapeutic work was conducted in the Center of Dermatology and Venereology, Baghdad Teaching Hospital, Baghdad, Iraq during the period from April 2018 through October 2019. Fifty of patients with scabies were involved in this study. All socio-demographic data that related to the disease were obtained from each patient. History and clinical examination was done for each case to establish the diagnosis. Fifty patients treated by ivermectin tablet 200 microgram per kg as a single dose on empty stomach and repeated after one week. The patients were seen regularly every 2 weeks for 4 weeks duration after stopping therapy, to re-asses cure and to report any local or systemic side effects. Results: A total of 50 patients were included in this study, 21 (42%) males and 29 (58%) females. The ages of males ranged from 5-47 with a mean 20.90±13.034 years; while the age range of females ranged from 3-67 (30.69±18.766) years. At the end of four weeks after stopping therapy , the response to treatment was as follows: Response in 49 (98%) patients and no response in 1 (2%) patients. No cutaneous or systemic side effects were noticed in any patients, while the recurrence or relapse rate was documented in 2 (4%) patients. Conclusion: Oral ivermectin had achieved cure of scabies in 98% of patients, hence it should be considered as a mass treatment in…
This article on dysplastic nevi was compiled and written in August 2004 but never published in a print journal. It is our opinion that now, 15 years later, the same conclusions documented in the initial article still exist. In fact, the further studies and reports strongly support the lack of malignancy (nor evidence of pre-cursors of malignancy) in correctly histologically diagnosed junctional or compound dysplastic nevi and the lack of need of re-excision of these nevi in almost all cases. 1,2,3,4
Introduction: Malignant melanoma is a lethal skin cancer which is on the rise despite increasing education on sun awareness. It is most common in young Caucasian individuals however any age or ethnicity can be affected. Discussion: There are four main types of malignant melanoma which include superficial spreading MM (most common), Nodular (most lethal), Acral lentignous melanoma and Lentigo maligna melanoma. Once it has metastasized the prognosis is poor but new treatments are giving us much better outcomes. Aim: The main aim of this study is to identify which MMs are most likely to metastasize based on the location with the two main groups being above neck and below neck. Methods and results: forty-five patients were included in the study, 37 were below neck and 8 were above neck. Out of the 37 below neck MM patients, none had distant metastases , but 25% of the above neck MM patients had distant metastases. Conclusion: This small study has demonstrated that above neck malignant melanoma is more likely to metastasize than below neck malignant melanoma despite advanced Tumor scores in the below neck subgroup.
