Introduction: Infantile haemangioma is the most common tumor in infancy. They are extremely heterogenous clinically. Established risk factors for infantile haemangioma include female sex, white ethnicity, prematurity, low birth weight and multiple gestation. There is a lack of demographic studies in the Asian population especially in the Malay ethnic group. Objective: To describe the demographics and clinical characteristics of infantile haemangioma in a tertiary centre in Malaysia. To describe associated complications and the need for therapeutic intervention. To determine whether there is any difference in demographics and clinical characteristics of infantile hemangiomas in a Malaysian population comprising predominantly Malay ethnic group with published reports of Western population. Design Retrospective review of patients with infantile haemangioma referred to the Paediatric Dermatology unit, Kuala Lumpur Hospital between January 2009 and May 2011. Main Outcome Measures: Demographic and clinical characteristics were summarized and compared with data from previous studies. The study included 50 patients (38 females and 12 males) with a mean age of 6.23 months (range 0.1 to 16 months) at presentation. 11(22%) patients were premature. The mean age of onset was 20 days (range 0 to 5 months). 18(37%) patients had a premonitory mark at birth. Of 62 hemangiomas in 50 patients, 45(72.5%) were localized, 5(8.1%) were segmental, 11(17.7%) indeterminate and 1(1.6%) multifocal. The most frequent location of the haemangiomas was in the face with 29(46.8%) lesions, followed by 10(16.1%) lesions in the head and neck, 10(16.1%) lesions in the extremities, 8(12.9%) lesions in the trunk and 5(8.1%) in the perineum. Complications that occurred included ulceration in 8(16%) patients, threat to vision in 7(14%), infection in 2 (4%) and bleeding in 6(12%) patients. Of the 50 patients, 24(48%) patients required interventions. These interventions included propranolol only in 12(24%) patients, prednisolone only in 4(8%), both propranolol and prednisolone in 5(10%), wound care in 2(4%) and pulse dye laser in 1(2%). Conclusion: The demographics and clinical characteristics of infantile haemangiomas in Malaysia are similar to published reports.

Temporal bone squamous cell carcinoma (TBSCC) is rare and poses difficulties in diagnosing, staging and management. We describe a case series with six patients who were diagnosed TBSCC, from January 2009 to June 2014, with median age of 62 years old. All patients presented with blood-stain discharge and external auditory canal mass, showing that these findings should highly alert the diagnosis of TBSCC. Three patients staged T3 and another three with T4 disease. High-resolution CT (HRCT) temporal findings were noted to be different from intraoperative findings and therefore we conclude that MRI should be done to look for middle ear involvement or other soft tissue invasion for more accurate staging. Lateral temporal bone resection (LTBR) and parotidectomy was done for four patients with or without neck dissection. Patients with positive margin, perineural invasion or parotid and glenoid involvement carry poorer prognosis and postoperative radiotherapy may improve the survival rate. One patient had successful tumor resection via piecemeal removal approach in contrast with the recommended en bloc resection shows that with negative margin achieved, piecemeal removal approach can be a good option for patients with T2-3 disease. In general, T4 tumor has dismal outcome regardless of surgery or radiotherapy given.

Purpose: To compare the image quality of the low-dose to the standard-dose protocol of MDCT scanning of the paranasal sinuses, based on subjective assessment and determine the radiation doses to the eyes and thyroid gland and dose reduction between these two protocols. Materials and Methods: 31 adult patients were scanned. Prior to scanning, thermoluminescent dosimeters (TLDs) were placed at 4 sites: outer canthus of right eye, outer canthus of left eye, inner canthus and anterior neck (thyroid gland). Every patient was scanned twice using the standard-dose protocol (100mAs) followed by the low-dose protocol (40mAs). The images were reviewed by 3 radiologists. Wilcoxon test was used as the test of significance for the image quality assessments. The paired sample t-test was used as the test of significance for the analysis of the radiation doses measured by the TLDs. Results: Of the 30 patients selected for analysis, this study showed no significant difference in the scores for the diagnostic image quality and the anatomical structures assessments between the two protocols. The average calculated mean entrance surface doses and standard deviation for the standard-dose and low-dose protocols were 12.40±1.39 mGy and 5.53±0.82 mGy respectively to the lens and 1.03±0.55 mGy and 0.63±0.53 mGy respectively to the thyroid gland. Conclusion: The reduction of mAs from 100 to 40 resulted in a significant reduction of the radiation doses to the lens and thyroid gland by 55.4% and 38.8% respectively without causing any significant effect to the diagnostic image quality and assessment of the anatomical structures.

Introduction: Infantile haemangioma (IH) is a common benign vascular tumour which is characterised by rapid proliferation in early infancy period followed by slow involution for years. The initial rapid growth and the location of haemangioma may result in significant morbidity. The introduction of oral Propranolol for the treatment of IH in recent years has seen many promising results though with potential risks. Objective: To review the demography, clinical pattern, management and outcome of patients with IH treated with propranolol in a paediatric dermatology referral centre. Methodology: A retrospective observational study of medical records of patients with IH treated with oral propranolol (maximum dose 2mg/kg/day) from May 2009 to May 2011 in Paediatric Institute, Kuala Lumpur Hospital. Results: A total of 17 patients (14 girls, 3 boys) were studied. They were 12 Malays (70.6%), 2 Chinese(11.8%), 2 Indians(11.8%) and 1 Indonesian (5.9%). Mostly term babies (88%). The age of presentation is from birth to 2 months old. The location of haemangiomas involve periocular (35.3%), perioral (17.6%), facial segmental (17.6%), nasal (5.9%), multiple (17.6%) and spinal (5.9%). They were started on Propranolol at a mean age of 5 months old except one at 2 years old. Five patients had concurrent adjunctive therapies. 70.6% had significant reduction of the size and colour of haemangiomas, 11.8% not significant, 11.8% unclear, and one patient defaulted follow up. Some patients developed wheezing episodes (29.4%), diarrhoea (17.6%), regurgitation (5.9%); but no serious consequences. Conclusion: Low dose oral propranolol is a safe and effective treatment with minor side effects from our experience.

OBJECTIVE: To determine the prevalence of hypoglycaemia using continuous glucose monitoring system (CGMS) among insulin-treated pregnant women with diabetes whose glycosylated haemoglobin (HbA1c) were <6.0% and identify the risk factors associated with hypoglycaemia occurrence.

METHODOLOGY: We conducted a cross-sectional study using 6-days CGMS to detect the prevalence of hypoglycaemia in 31 insulin-treated pregnant women with diabetes who achieved HbA1c <6.0%. Patients were required to log-keep their self-monitoring blood glucose (SMBG) readings and hypoglycaemia events.

RESULTS: Eight women experienced confirmed hypoglycaemia with additional seven experienced relative hypoglycaemia, giving rise to prevalence rate of 45.2% (one had both confirmed and relative hypoglycaemia). Nine relative hypoglycaemia and 17 confirmed hypoglycaemic events were recorded. Sixteen (94%) out of 17 confirmed hypoglycaemia events recorded by CGMS were asymptomatic and were missed despite performing regular SMBG. Nocturnal hypoglycaemia events were recorded in seven women. Univariable analysis did not identify any association between conventional risk factors and hypoglycaemia events in our cohort.

CONCLUSION: Insulin-treated pregnant women with diabetes who achieved HbA1c < 6.0% were associated with high prevalence of hypoglycaemia. Asymptomatic hypoglycaemia is common in our cohort and frequently missed despite regular SMBG. Present study did not identify any association between conventional risk factors and hypoglycaemia events in our cohort.

This is a case report of a 22-year-old Filipino male, morbidly obese, not known to have diabetes mellitus (DM) who presented with diabetic ketoacidosis on initial diagnosis. He had a phenotype of type 2 DM (T2D) but an initial presentation consistent with type 1 DM (T1D). Insulin therapy was eventually discontinued but he maintained good glycemic control with diet alone. C-peptide showed adequate increase after a mixed-meal diet and GAD65Ab was negative, thus he was diagnosed with ketosis-prone DM (KPDM). The increasing prevalence of obesity challenges the classic phenotype of patients with DM, with many patients presenting as an obese type T1D, and being diagnosed with T2D at a younger age. This complicates how to classify the patient’s diabetes, and the clinical profile is sometimes insufficient to make the proper diagnosis. In these cases, immunologic markers and assessment of β-cell function are important tools to differentiate between T1D and T2D, to direct management plans and to anticipate complications.

INTRODUCTIONRobotic-assisted gynaecologic surgery is gaining popularity and it offers the advantages of laparoscopic surgery whilst overcoming the limitations of operative dexterity. We describe our experience with the fi rst 40 cases operated under the GRACES (Gynaecologic Robot- Assisted Cancer and Endoscopic Surgery) programme at the Department of Obstetrics & Gynecology, National University Hospital, Singapore.

MATERIALS AND METHODSA review was performed for the fi rst 40 women who had undergone robotic surgery, analysing patient characteristics, surgical timings and surgery-related complications. All cases were performed utilising the da Vinci® surgical system (Intuitive Surgical, Sunnyvale, CA) with 3 arms and 4 ports. Standardised instrumentation and similar cuff closure techniques were used.

RESULTSSeventeen (56%) were for endometrial cancer and the rest, for benign gynaecological disease. The mean age of the patients was 52.3 years. The average docking time was 11 minutes (SD 0.08). The docking and operative times were analysed in tertiles. Data for patients with endometrial cancer and benign cases were analysed separately. There were 3 cases of complications- cuff dehiscence, bleeding from vaginal cuff and tumour recurrence at vaginal vault.

CONCLUSIONOur caseload has enabled us to replicate the learning curve reported by other centres. We advocate the use of a standard instrument set for the fi rst 20 cases. We propose the following sequence for successful introduction of robot-assisted gynaecologic surgery - basic systems training, followed shortly with a clinical case, and progressive development of clinical competence through a proctoring programme.

INTRODUCTIONIncreasing resistance in Escherichia coli and Klebsiella pneumoniae to firstline antibiotics makes therapeutic options for urinary tract infections (UTIs) challenging. This study investigated the in vitro efficacies of 6 antibiotics against multidrug resistant (MDR) uropathogens.

MATERIALS AND METHODSMinimum inhibitory concentrations to ceftibuten, cefpodoxime, fosfomycin, mecillinam, temocillin, and trimethoprim were determined against 155 MDR-isolates of E. coli and K. pneumoniae. The presence of extended-spectrum beta-lactamases (ESBL) and plasmid-borne AmpC enzymes was determined by phenotypic testing with genotyping performed by multiplex polymerase chain reaction.

RESULTSTemocillin demonstrated highest susceptibility rates for both E. coli (95%) and K. pneumoniae (95%) when breakpoints for uncomplicated UTIs were applied; however, temocillin susceptibility was substantially lower when "systemic infection" breakpoints were used. Fosfomycin demonstrated the best in vitro efficacy of the orally available agents, with 78% and 69% of E. coli and K. pneumoniae isolates susceptible, respectively. The next most effective antibiotics were ceftibuten (45%) and mecillinam (32%). ESBL and ampC genes were present in 47 (30%) and 59 (38%) isolates.

CONCLUSIONThis study demonstrated few oral therapeutic options for MDR-uropathogens, with fosfomycin demonstrating the best in vitro activity.

This study aims to determine the prevalence of lower urinary tract symptoms (LUTS) and level of awareness among male outpatients in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A questionnaire consisting of demographic data, questions related to knowledge, attitude and practice on BPH and the International Prostate Symptom Score (IPSS) was used for this study. Uroflowmetry and bladder scan were used to evaluate the function of the urinary tract and severity of BPH. Urine dipstick was done for glycosuria, proteinuria and haematuria. A total of 220 respondents were surveyed. The prevalence of moderately and severely symptomatic LUTS was 42.7%. The most commonly reported LUTS were nocturia (78.2%), frequency (58.2%) and incomplete emptying (44.6%). The prevalence of glycosuria, proteinuria and haematuria were 23.6%, 11.4% and 1.8% respectively. There was a significant association between increasing age with the severity of LUTS (p=0.005). Out of 102 respondents with voided urine volume greater than 150 mL, there was a significant decrease in maximum (Qmax) (p=0.039) and average (Qave) urine flow rates with every 10 years increase of age (p=0.001). The majority of respondents (59.5%) have heard of BPH before. Over 78.2% of the respondents would seek medical attention if they have LUTS with 15.9% saying they would seek traditional treatment. In conclusion, the prevalence of LUTS was high and the level of awareness was satisfactory.
