Background Autoimmune bullous diseases (ABD) represent a group of chronic blistering dermatoses in which management is often challenging. Epidemiologic data on these diseases in Malaysia has been limited. Objectives Our purpose was to study the spectrum of the various ABD presented to the Department of Dermatology, Ipoh Hospital, and to determine the clinico-epidemiological pattern of the 2 main ABD, namely pemphigus and bullous pemphigoid. Methodology We performed a retrospective review of records for all patients who were diagnosed with ABD confirmed by histopathology and direct immunofluorescence test in this centre between 2001 and 2005. The data were analyzed with regard to age, sex, ethnicity, subtypes of ABD, treatment provided and outcome. Results There were a total of 79 cases of ABD presented to us during this period. Bullous pemphigoid was observed to be the commonest (60.8%) followed by the pemphigus group (36.7%) with the mean incidence of 0.45/100,000/year and 0.28/100,000/year respectively.44% of patients were of ethnic Chinese origin. There was an overall female preponderance. The mean age of presentation was 65.5 years for bullous pemphigoid and 55 years for pemphigus group. The mean duration of disease before presentation was 1.6 months for bullous pemphigoid and 6.3 months for pemphigus. Various combinations of immunosuppressive agents were used to treat the patients. 48% of bullous pemphigoid cases were controlled with prednisolone alone while 67.9% of pemphigus group required at least 2 immunosuppressive agents to achieve disease control. Conclusion In our study population, bullous pemphigoid was more frequently seen than pemphigus.

Background Atopic eczema is a common dermatological condition seen in our practice in which the mainstay of treatment is topical medications. One of the main reasons for poor clinical response to therapy in atopic eczema is the lack of understanding of topical preparation usage and thus poor adherence to treatment. Objectives The aim of this study is to determine the effect of explanation and demonstration of topical medication on the clinical response of atopic eczema. Methodology Twenty newly diagnosed patients with atopic eczema who fulfilled the study criteria were recruited and randomized consecutively into 2 groups - A & B. All patients were assessed on the severity of the eczema using the six area, six sign atopic dermatitis severity score (SASSAD) and patients’ assessment of itch, sleep disturbance and irritability were recorded on 10-cm visual analogue scales. They were also assessed on their level of understanding on the proper usage of topical medications using a questionnaire. Group A then received explanation and demonstration on how to apply the topical medications while Group B was not educated on these. They were followed up 2 weeks after treatment and were re-evaluated on their understanding and the severity of their skin condition. This was followed by education by a dermatology nurse on the proper usage of topical medications for both groups. A third evaluation was done 2 weeks later. Results At baseline, 70% of the patients did not understand the potency of topical corticosteroid and between 20-30% of them did not know the correct sites, frequency, time and duration of each topical application prescribed. About two thirds of the patients claimed that they did not receive any explanation or demonstration from either their doctors or the pharmacy dispensers. After education on the proper usage of topical medications, the level of understanding improved to 100% for group A at visit 2 and group B at visit 3. A clinical improvement as measured by SASSAD score reduction was seen in both groups. In group A, a significant SASSAD score reduction of 49.5% (P=0.003) was seen after 2 weeks and it was sustainable, as evidenced by a further reduction to 67% (p=0.001) by week 4. In group B, a significant SASSAD score reduction (64.8%; p=0.002) was seen only at week 4 after patient education and demonstration. The magnitude of improvement in patients’ symptoms which included itch, sleep disturbance and irritability, measured by the patient using visual analog score, were only significant for group A after 4 weeks. Conclusions This study reinforces the importance of explanation and demonstration on the proper usage of topical medications in achieving better clinical response. Failure to explain on the use of topical medications may lead to patient dissatisfaction, poor compliance and lack of treatment efficacy.

Introduction The efficacy of cyclosporine in the treatment of psoriasis is well established. However widespread use of it has been limited by concerns over adverse effects such as hypertension, renal impairment and the potential risk of malignancy. The aim of this study is to determine the profile of our local psoriasis patients treated with cyclosporine, their response to treatment, their tolerability and the side-effects experienced. Materials and Methods This is a retrospective study of all psoriasis patients treated with cyclosporine for more than one month from January 1996 to June 2007 at the Department of Dermatology Ipoh Hospital. Results There were a total 21 patients, 8 males and 13 females. Their mean age was 40 years. There were 7 Malays, 10 Chinese and 4 Indians. Cyclosporine was given as the second or third line of treatment. The average starting dose was 2.76mg/kg and maximum dose was 3.89mg/kg. Best response was noted after 3 months of treatment. Thirteen (61.9%) patients had excellent response, 4(19%) had good response, 3 (14.3%) had moderate response and 1(4.8%) had poor response. Thirteen (61.9%) patients developed raised serum creatinine level exceeding 30% of the baseline while on treatment but all of them improved when the dosages of cyclosporine were reduced. None of them developed renal failure. There were 5 patients who had hypertension while on cyclosporine therapy, 2 of them required antihypertensive agents while for the remaining 3, blood pressure normalized after dosage reduction. Other side effects reported include gastrointestinal upset, gum hypertrophy and hypertrichosis. Conclusion Cyclosporine is effective in the treatment of psoriasis but close monitoring of serum creatinine and blood pressure is needed.

Herpes simplex virus (HSV) infection is one of the common opportunistic viral infections that may occur in human immunodeficiency virus (HIV) - infected patients. The natural history of HSV infection is often altered in this group of patients. Characteristically, genital herpes presents with multiple painful vesicles and erosions in immunocompetent patients. However, clinical presentations in immunocompromised patients are frequently severe and atypical which may lead to a delay in diagnosis and treatment. Genital herpes enhances transmission of HIV infection and hence early detection of this condition is important to reduce transmission of HIV and HSV.

Pemphigus foliaceous (PF) is an autoimmune blistering disease resulting from acquired immunoglobulin G autoantibodies against desmoglein 1 of the skin, which is one of the adhesion molecules of keratinocytes. Clinically patients with PF develop crusted and scaly erosions mainly over the seborrhoeic distribution i.e. the face, scalp and upper trunk. Mild cases of PF may be localized but in some cases it may progress to erythrodermic exfoliative dermatitis. There is however no mucosal involvement in PF in contrast to pemphigus vulgaris and paraneoplastic pemphigus. Light microscopy of lesional biopsy shows subcorneal acantholysis. Direct immunofluorescence study of perilesional skin reveals presence of intraepithelial intercellular deposit of IgG and C3. We describe 2 cases of PF in the presence of thymoma, a relatively rare association, which could further support the fact of thymoma associated autoimmune disease.

Background Naevus of Ota was first described in 1939 by Ota M. It is characterized by a bluish-gray mottled hyperpigmentation in the distribution of the trigeminal nerve. It affects between 0.014 - 0.6% of the Asian population. It is not only physically disfiguring but may be associated with tremendous psychosocial impact on the patient. The aim of the study is to determine the demographic data of local patients with naevus of Ota, their response to treatment with Q-switched 1064nm Nd:YAG laser, complications and recurrence. Materials and Methods A retrospective analysis of all patients with naevus of Ota treated with Q-switched 1064nm Nd:YAG laser between January 1998 to December 2007 was conducted at the dermatology clinic, Kuala Lumpur Hospital. Patients’ demographic data, clinical characteristics, response to Q-switched 1064nm Nd:YAG laser and the complications were reviewed. Results A total of 50 patients with naevus of Ota were treated with Q-switched 1064nm Nd:YAG laser. There were 42 female and 8 male patients with a F : M ratio of about 5:1. The mean age of presentation was 31 years old (11-60 years). More than half were Chinese patients (56%) followed by Malays (38%), Indian (2%) and others (4%). Seventy four percent of the patients had Fiztpatrick skin-type IV and the rest skin type V. Ninety two percent of the patients had unilateral trigeminal dermatomal involvement while 8% had bilateral trigeminal dermatomal involvement. Of the 15 patients who were referred to the ophthalmologist, 10 were found to have scleral involvement and none had glaucoma. Patients who had 2 treatments (13 patients) did not have any significant lightening of their lesions. In the remaining 37 patients who had 3 sessions (mean = 5.7, range 3 -15 sessions), 9 patients (24.3%) reported the response as good (51-75% lightening); 17 patients (45.3%) as excellent (>75% lightening) and 8 patients (22%) had near complete lightening (>90%). None reported any complications or recurrence. Conclusion Q-switched 1064nm Nd:YAG laser is an effective and safe treatment modality for patients with naevus of Ota.

Background Autoimmune pemphigus is a potentially life threatening bullous disease. The cornerstone of treatment is systemic corticosteroids. However, adjuvant therapy with immunosuppressant drugs is commonly used to improve disease control and alleviate the high morbidity and mortality associated with the use of corticosteroids. Adjunctive treatment with pulse intravenous cyclophosphamide may be more efficacious and less toxic than other immunosuppressants. Objective To retrospectively review the clinical outcome of 18 patients with recalcitrant pemphigus who were treated with cyclophosphamide over the past 10 years. Methodology A retrospective study was conducted between 1985 and 2009 in thirteen Malaysian dermatology centres. Data collected were analysed for comparison of relapse rates, compliance rates and adverse drug effects between the 2 regimes. Results Eighteen patients were included in this audit of which 12 patients had pemphigus vulgaris and 6 patients had pemphigus foliaceous. Prior to treatment with cyclophosphamide, fourteen patients were on azathioprine, three were given intravenous immunoglobulin, and two were prescribed dapsone; however all these patients were either unresponsive, intolerant or suffered serious side-effects with these drugs. Subsequently, 7 patients (median age: 31 years) received a combination of pulse intravenous cyclophosphamide and either intravenous dexamethasone or methylprednisolone. These seven patients received between 2 to 21 pulses of intravenous cyclophosphamide and steroids at monthly intervals with oral prednisolone and cyclophosphamide (50-100mg) in between pulses. The remaining 11 patients (median age: 46 years) received oral cyclophosphamide and corticosteroids. Of the 18 patients in our cohort, 15 achieved control and consolidation of disease activity at an average of 4 weeks and 10 weeks respectively. The remaining three patients are yet to achieve disease control. The total duration of treatment with cyclophosphamide ranged from 2 to 62 months with a cumulative dose ranging from 2.95g to 93.55g. Four patients achieved partial remission on minimal therapy and 3 achieved complete remission. None of patients experienced serious side effects. Conclusion Cyclophosphamide may be an alternative treatment option in patients in patients with pemphigus who fail to respond to standard therapy. Controlled trials are needed to further evaluate the efficacy and safety of this therapy.

Wegener’s granulomatosis is a rare multisystem necrotizing granulomatous vasculitis aff e c t i n g small - and medium-sized vessels. Its clinical manifestations can be nonspecific during the initial stages and indistinguishable from a variety of neoplastic, infectious, and inflammatory diseases. The disease may run a course from indolence to one of rapid progression leading to life-threatening multiorgan failure. We report a rare case of rapidly progressing Wegener’s granulomatosis.

Background Antibiotic therapy directed against Propionibacterium acnes (P. acnes) has been a mainstay of treatment in acne vulgaris for more than 40 years. Prolonged antibiotic usage has been associated with emergence of antibiotic-resistant P. acnes and is linked to treatment failure. Little work has been done in Malaysia on drug resistance in P. acnes and there is no surveillance data on this aspect to guide the clinical decision. Objective This study aims to evaluate antibiotic sensitivity of P. acnes isolated from patients with acne vulgaris in Kuala Lumpur Hospital, Malaysia. Methods This is a non interventional, single centered, cross-sectional hospital-based survey of antibiotic sensitivity of P. acnes isolated from patients with acne vulgaris in Kuala Lumpur Hospital from January 2010 to June 2010. Results A total of 100 patients were recruited in our study. P. acnes was isolated in 53% of patients and 11% had gram negative organism. Antibiotic resistant P. acnes was found in 15.1% of positive isolates. Clindamycin resistance was the highest (15.1%) followed by erythromycin (7.5%), doxycycline (5.7%), tetracycline (1.9%) and minocycline (0%). Isolates of antibiotic resistant P. acnes was significantly higher in patients treated with antibiotics within the last 6 months (29%) as compared with non antibiotic treated patients (0%) (p<0.05).The mean duration of prior antibiotic treatment was significantly longer in the group of antibiotic resistant P. acnes as compared with antibiotic sensitive P. acnes (17.13 weeks vs 5.74 weeks, p<0.05). Conclusion Antibiotic resistant P. acnes is present locally with clindamycin and erythromycin accounting for the highest resistance. Longer duration of antibiotic treatment predisposes to antibiotic resistant P. acnes and may also induce emergence of gram negative organisms. Strategies to reduce antibiotic resistance should be emphasized when prescribing antibiotic for acne vulgaris in order to achieve optimal therapeutic results while reducing the potential for antibiotic resistance.

Objective To sum up operative experience and prevention of complications while resecting the hepatic hilar tumor. Methods 14 cases with hepatic hilar tumor were analyzed in respect of operative method,complications, experience and prevention of complications. Results Some peri-operative complications happened. such as massive hemorrhage in 2 cases,billiary fistula in 1 case,hepatic failure in 1 case and tumor remained at resection edge in 1 case. No patients died during the operation. Conclusion The resection of hepatic hilar tumor is very difficult and risky,safety of surgery can be improved by paying attention to pre-operative evaluation and preparation,as well as carefulness during operation.
