Methicillin-resistant Staphylococcus aureus colony variants (SCVs) are frequently auxotrophic for hemin, menadione, thiamine, and CO2 involved in biosynthesis of the electron transport chain element. This phenotype grows slowly, and forms very small, nonhemolytic colonies in routine culture, so it may be led to the misidentification of this organism. We isolated an organism with catalase-positive, gram-positive cocci in cluster from the urine of a 55-years-old woman with persistent and relapsing bladder stone, who had undergone the antibiotic treatment with cefotaxime, ceftizoxime, amikacin, and/or micronomicin, intermittently for three years. The possibility of SCVs should have been ruled out because this organism didn't grow on Mueller-Hinton agar (MHA) for the susceptibility test. It formed small colonies on blood agar plate overnight, and grew only on MHA with supplement of hemin, or with 5% CO2. This organism was coagulase-positive, DNase-positive, manitol-salt positive, and identified as S. aureus with VITEK GPI card. The susceptibility test could be performed after adding hemin(1mg/mL) into bacterial suspension and showed susceptibility against vancomycin, teicoplanin, and rifampin. Because these phenotypes can be misidentifide as other non-pathogenic organisms due to their atypical characteristics, we should consider SCVs in case of small, nonhemolytic colonies with catalase-positive, gram-positive cocci in cluster, showing no growth on MHA. In addition, infections caused by SCVs are recently recognized in relation to persistent and relapsing infection, so they could be isolated from the patients with long-term antibiotic therapy.

Background and Objective: In 1998/99, an outbreak of Nipah virus encephalitis occurred in several pig-farming communities in Malaysia. It was associated with a high mortality rate and persistent neurological defi cits among many survivors. This mixed method study aimed to examine the longterm socio-economic consequences of the illness on affected pig farmers and their families in Bukit Pelanduk, Negeri Sembilan. Methods: A quantitative cross sectional survey was conducted in 2008 on 78 former patients or their kin from 61 households (46.2% males, mean age = 48.7 years) in Bukit Pelanduk via face-to-face interviews. This was followed by qualitative in-depth interviews with 20 respondents. Results: The immediate treatment costs were not a major burden to most households. Majority of the patients (92%) required inpatient care and most obtained free care from public hospitals. Households relied mainly on savings and support provided by the public and family members during the outbreak. However, many former patients found their low educational qualifi cations prevented them from obtaining good alternative employment after their recovery. This had negatively affected their households’ living standards. As a result, there had been a renewed appreciation of the value of education for their young, and one of their main concerns was the fi nancial burden of educating their children. Conclusion: Free public health care protected most households from high medical costs. However, household living standards had dropped due to limited alternative employment opportunities. Education has been identifi ed as a key to improving the long term welfare of affected households.

Background: Normal saline (NS) is a common fluid of choice in neurosurgery and neurointensive care unit (ICU), but it does not contain other electrolytes and has the potential to cause hyperchloremic metabolic acidosis with prolonged infusion. These problems may be reduced with the availability of balanced fluid (BF), which becomes a more physiological isotonic solution with the presence of complete electrolyte content. This study aimed to compare the changes in electrolytes and acid–base between NS and BF (Sterofundin® ISO) therapy for post-operative severe traumatic brain injury (TBI) patients in neuro-ICU. Methods: Sixty-six severe TBI patients who required emergency craniotomy or craniectomy and were planned for post-operative ventilation were randomised into NS (n = 33) and BF therapy groups (n = 33). The calculation of maintenance fluid given was based on the Holliday-Segar method. The electrolytes and acid–base parameters were assessed at an 8 h interval for 24 h. The data were analysed using repeated measures ANOVA. Results: The NS group showed a significant lower base excess (-3.20 versus -1.35, P = 0.049), lower bicarbonate level (22.03 versus 23.48 mmol/L, P = 0.031), and more hyperchloremia (115.12 versus 111.74 mmol/L, P < 0.001) and hypokalemia (3.36 versus 3.70 mmol/L, P < 0.001) than the BF group at 24 h of therapy. The BF group showed a significantly higher level of calcium (1.97 versus 1.79 mmol/L, P = 0.003) and magnesium (0.94 versus 0.80 mmol/L, P < 0.001) than the NS group at 24 h of fluid therapy. No significant differences were found in pH, pCO2, lactate, and sodium level. Conclusion: BF therapy showed better effects in maintaining higher electrolyte parameters and reducing the trend toward hyperchloremic metabolic acidosis than the NS therapy during prolonged fluid therapy for postoperative TBI patients.

Primary neuroendocrine small cell carcinoma of the parotid gland is a rare malignant tumor, the clinical diagnosis is difficult. This article report a primary parotid neuroendocrine small cell carcinoma which was initially diagnosed of adenoid cystic carcinoma of the parotid gland and was operated, but recurred 2 years later. The artide discuss about the characteristic of this disease and review the relevant literatures.

Childhood obesity is a global epidemic, which leads to the increasing number of studies on genetic locations associated with obesity-related traits. Polymorphisms of insulin (INS) gene have been shown to be associated with obesity-related phenotypes in Europeans; while insulin receptor (INSR) gene has been associated with energy regulation. Therefore, this study was conducted to investigate the association between the INS (rs689) and INSR (rs3745551) gene polymorphisms with childhood obesity risk in a Malay childhood population. Normal weight (538) and overweight or obese (557) children aged 6-12 years old were genotyped using semi-automated Sequenom iPLEX® Gold. Body mass index (BMI) was calculated from measured body weight and height. The rs689 (T/T: 0.006, A/T: 0.159 and A/A: 0.835) and rs3745551 (G/G: 0.054, A/G: 0.378 and A/A: 0.568) genotype distributions were consistent with Hardy Weinberg equilibrium. The T-minor allele frequency for rs689 was 8.6% and G-minor allele frequency for rs3745551 was 24.3%. Minor allele of INS gene polymorphisms significantly increased risk of obesity among Malay children (sex- and age-adjusted OR=1.580; 95%CI: 1.134-2.201). However, INSR gene polymorphisms were not significantly associated with childhood obesity. In conclusion, the polymorphisms of INS gene, rather than INSR gene, were associated with childhood obesity in the Malay population.

Juvenile hyaline fibromatosis is a rare disorder probably inherited as an autosomal recessive trait. It is characterized by multiple slowly growing subcutaneous nodules, hypertrophy of gingiva, flexion contracture, and radiolucent bone destruction. The histological features of the tumor-like lesions are characterized by the deposition of amorphous hyaline material in which spindle shaped cells are embedded. We report a case of juvenile hyaline fibromatosis in a 26 year-old-woman. She had multiple subcutaneous nodules in scalp, ear, forearms, right knee, and back. Surgical excision of the tumors in the scalp and ear was done. The largest one measured 13 9 6 cm, and had homogeneous, grayish yellow cut surface with calcification. Light microscopic examination showed abundant eosinophilic hyaline material with extensive calcification and metaplastic bone formation. Spindle cells were rarely observed at the periphery of the tumor. Hyaline matrix was PAS positive, diastase resistant, and alcian blue negative. Scattered spindle cells were positive for vimentin but negative for S-100 protein and smooth muscle actin. There were many reports regarding early lesions of juvenile hyaline fibromatosis; however in this patient, tumor existed for more than 20 years and the histology was somewhat different from the early lesions reported in the literature.

OBJECTIVE: Lister's tubercle is used as a standard anatomical landmark in hand surgery and arthroscopy procedures. In this study, we aimed to evaluate and propose a classification for anatomical variants of Lister's tubercle. MATERIALS AND METHODS: Between September 2011 and July 2014, 360 MRI examinations for wrists performed using 1.5T scanners in a single institution were retrospectively evaluated. The prevalence of anatomical variants of Lister's tubercle based on the heights and morphology of its radial and ulnar peaks was assessed. These were classified into three distinct types: radial peak larger than ulnar peak (Type 1), similar radial and ulnar peaks (Type 2) and ulnar peak larger than radial peak (Type 3). Each type was further divided into 2 subtypes (A and B) based on the morphology of the peaks. RESULTS: The proportions of Type 1, Type 2, and Type 3 variants in the study population were 69.2, 21.4, and 9.5%, respectively. For the subtypes, the Type 1A variant was the most common (41.4%) and conformed to the classical appearance of Lister's tubercle; whereas, Type 3A and 3B variants were rare configurations (6.4% and 3.1%, respectively) wherein the extensor pollicis longus tendon coursed along the radial aspect of Lister's tubercle. CONCLUSION: Anatomical variations of Lister's tubercle have potential clinical implications for certain pathological conditions and pre-procedural planning. The proposed classification system facilitates a better understanding of these anatomical variations and easier identification of at-risk and rare variants.
