Introduction Skin cancer is ranked the ninth commonest cancer among males and
tenth among females in Malaysia.
Objectives To review the pattern of skin cancers at University Malaya Medical Centre
(UMMC).
Methods This is a retrospective review of all histo-pathological confirmed skin
cancers at UMMC from 2004 till 2010.
Results Among the 155 patients reviewed, basal cell carcinoma (BCC) was the
commonest skin cancer (44.5%), followed by squamous cell carcinoma (SCC) (27.1%)
and malignant melanoma (MM) (11.6%). The nodulo-ulcerative subtype made up
46% of all BCC while 50% of MM was of acral lentiginous subtype. Patients with
BCC were significantly older (>60 years old), (p=0.003). A majority of skin cancers
were found on the head and neck.
Conclusion BCC was the commonest skin cancer, with significantly older patients
and located mainly on head and neck. MM was the least common skin cancer but
associated with the highest mortality.

Background: Skin cancer is ranked the ninth commonest cancer among male and tenth among female in Malaysia.
Objective: To determine the pattern of skin cancers and demography of skin cancer sufferers in University Malaya Medical Centre (UMMC).
Methods: This is a retrospective review of all histo-pathologically confirmed skin cancers in UMMC from 2004 to 2010. Patients with incomplete or missing data were excluded.
Results: A total of 155 patient records were reviewed. The commonest skin cancer was basal cell carcinoma (BCC) (44.5%), followed by squamous cell carcinoma (SCC) (27.1%) and malignant melanoma (MM) (11.6%). The other skin cancers
included dermatofibrosarcoma protuberans and cutaneous lymphoma (5.2% each), extramammary Paget’s disease 3.2%
and Kaposi sarcoma 2.6%. A majority (78%) of BCC was of nodulo-ulcerative subtype while 50% of MM was of acral
lentiginous melanoma subtype. BCC had a significantly higher number of patients from the older age group (>60 years old) compared to other skin cancers (p=0.003). SCC had significantly more male patients than other skin cancers (p=0.006). With the exception of MM, a majority of skin cancers were found on the head and neck.
Conclusions: BCC was the commonest skin cancer followed by SCC and MM. Patients with BCC were older with a female preponderance and mainly located on the head and neck. MM was the least common of the three major skin cancers, but has the highest risk of metastasis and mortality.

Background: Atopic Dermatitis (AD) is a chronic relapsing, pruritic inflammation of the skin which is often colonized by Staphylococcus aureus. Antibiotic resistance of S. aureus is a constant challenge for clinicians who manages atopic dermatitis.
Aim: To determine S. aureus antibiotic resistance pattern among patients with non-infected atopic dermatitis and its association with disease severity.
Methods: One hundred and seventy eight participants (89 AD patients and 89 controls) were recruited from Universiti Malaya Medical Centre (UMMC). Participants were subjected to a questionnaire on demographics, personal and family medical conditions as well as antibiotic administration. AD severity were determined using Scoring Atopic Dermatitis (SCORAD). Skin swab was taken from eczematous lesion in patients and from left forearm in controls. Antibiotic susceptibility towards methicillin, vancomycin, rifampicin, fusidic acid, erythromycin, gentamicin, clindamycin, sulphamethoxazole, cefuroxime and penicillin were determined using disk diffusion method. Results for antibiotic resistance were categorized as none, sensitive and resistant.
Results: Colonization of S. aureus in AD were significantly higher than control (p<0.001). Highest antibiotic resistance was reported for Penicillin (32/39, 82.1%), followed by Fusidic Acid (7/39, 17.9%) as well as Clindamycin and Erythromycin (3/39, 7.7% respectively). Two AD patient (5.1%) were resistant to Gentamicin. In addition, 1 AD patient (2.6%) was resistant towards Methicillin, Sulfamethoxazole and Cefuroxime respectively. No antibiotic resistance was reported for Vancomycin and Rifampicin among the AD patients.
Conclusion: High resistance were found for Penicillin and Fusidic acid. Their usage and prescription should be reduced to preserve its sensitivity.

Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to
medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as compared to myomectomy and hysterectomy. MRgFUS can be offered to a majority of patients suffering from symptomatic uterine fibroids. It has been suggested that the use of broader inclusion criteria as well as the mitigation techniques makes it possible to offer MRgFUS to a much larger subset of patients than previously believed. This paper will describe how MRgFUS treatment for uterine fibroids
is performed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia.

Improvements in the overall treatment of patients with aggressive, large tumours involving the bone have made it possible to preserve and salvage limbs instead of amputating them. Each patient is unique in his clinical presentation and social circumstance. The different reconstructive options available allow us to choose the most appropriate method suited to the particular patient and with minimal delay, even when resources are limited. The patient and the relatives actively participate in the choice. The early experience of the different techniques for reconstructing these bone defects at our hospital are presented in this paper.

The present study aimed to determine the factors associated with CKD stage 3b among type 2 diabetics attending primary care follow-up, specifically the role
of angiotensin blockade dosage. This was a pilot unmatched case-control study conducted in a teaching primary care centre. Clinical data of 25 cases of diabetic patients with CKD stage 3b (GFR 30-45ml/min/1.73m2) in 2012 were selected for this study, as well as 103 controls who were diabetic patients with GFR more than 45ml/min/1.73m2 in 2012. Systematic random sampling was employed. Data was
obtained from patients’ diabetic records, computerised clinical medical information system and medical case notes. Univariate analysis was done using Chi-square,
t-test, Fisher’s exact test and Mann-Whitney U-test. Multiple logistic regression was used to determine the associated factors for development of CKD stage 3b. Cases
and controls were different in terms of age, duration of diabetes, use and dosage of angiotensin blockade medications, systolic blood pressure and baseline GFR.
Multiple logistic regression revealed that systolic blood pressure (Adjusted OR= 1.08, 95% CI= 1.02-1.14, p=0.013) and baseline GFR (Adjusted OR= 0.90, 95% CI= 0.85-0.95, p<0.001) was significantly associated with the development of CKD stage 3b among diabetics. Maximizing the dose of angiotensin blockade had a protective effect (Adjusted OR= 0.14, 95% CI=0.85-0.95, p=0.025). The results of the present study supports the need for good control of systolic blood pressure among diabetic patients to reduce the risk of chronic kidney disease progression. Dose of angiotensin blockade medications should be optimised in these patients.

A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from one of the pupae occurring within a week were identified as Exoristobia philippinensis Ashmead (Hymenoptera: Encyrtidae). Another observation was made whereby a pupa of C. rufifacies was predated by a muscid larva, Ophyra spinigera (Stein). The larva squeezed into the pupa and consumed the contents. This paper report C. rufifacies as a new host record for E. philippinensis in Malaysia and highlighted the predatory behavior of O. spinigera larva in natural environment.

A 73-year-old Chinese man was admitted to the Accident and Emergency Premorbid Ward of a
local hospital in Malaysia. The patient complained of shortness of breath with cough and was in a
semi-conscious state. He was later admitted to an intensive care unit (ICU) of the hospital. Six days
after admission 5-6 maggots were recoverd from the nasal cavity. The maggots were identifi ed as the
third-instar larvae of Lucilia cuprina Wiedmann (Diptera: Calliphoridae) based on the morphological
characteristics. This patient was classifi ed as having nosocomial myiasis. The presence of the third
instar larvae indicated that the infestation was not more than three to four days. An adult sarcophagid
identifi ed as Parasarcophaga rufi cornis (Fabricius) caught in the ICU where the patient was warded
provided further evidence of the potential for the nosocomial infestation.
