    In the contemporary era, the demand for orthodontic treatment is ever rising. Orthodontic treatment duration can range from a year to a few years. Our aim is to assess the available techniques of categorising treatment effectiveness in patients with cleft lip and palate (CLP) and to study their effect on improvement of treatment outcomes. The electronic databases including Medline-PUBMED, Science Direct, and ISI Web of Knowledge were searched from 1987 to 2013, and 40 311 relevant articles were found. Of these, we identified 22 articles including original articles as well as literature reviews. The different parameters and indices that are applied to speed-up orthodontic treatment outcomes in patients with CLP were identified as the GOSLON Yardstick, 5-year-old index, EUROCRAN index, Huddart Bodenham system, modified Huddart Bodenham system, GOAL Yardstick and, Bauru-Bilateral Cleft Lip and Palate Yardstick. This overview can create better awareness regarding the uses, advantages, and disadvantages of the different indices. It can enable better assessment and provide the impetus needed for a sustained upgrade in the standards of care for CLP in daily orthodontics.

    Obesity is a fast-emerging epidemic in the Asia-Pacific region, with numbers paralleling the rising global prevalence within the past 30 years. The landscape of gut diseases in Asia has been drastically changed by obesity. In addition to more non-specific abdominal symptoms, obesity is the cause of gastro-oesophageal reflux disease, various gastrointestinal cancers (colorectal cancer, hepatocellular carcinoma, oesophageal adenocarcinoma, gastric cardia adenocarcinoma, pancreatic cancer and gallbladder cancer) and non-alcoholic fatty liver disease. Abnormal cross-talk between the gut microbiome and the obese host seems to play a central role in the pathogenesis, but more studies are needed.

    BACKGROUND: The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-assessment scale designed to evaluate anhedonia in various psychiatric disorders. In order to facilitate its use in Malaysian settings, our current study aimed to examine the validity of a Malay-translated version of the SHAPS (SHAPS-M).
    METHODS: In this cross-sectional study, a total of 44 depressed patients and 82 healthy subjects were recruited from a university out-patient clinic. All participants were given both the Malay and English versions of the SHAPS, Fawcett-Clark Pleasure Scale (FCPS), General Health Questionnaire 12 (GHQ-12), and the Beck Depression Inventory (BDI) to assess their hedonic state, general mental health condition and levels of depression.
    RESULTS: The results showed that the SHAPS-M has impressive internal consistency (α = 0.96), concurrent validity and good parallel-form reliability (intraclass coefficient, ICC = 0.65).
    CONCLUSION: In addition to demonstrating good psychometric properties, the SHAPS-M is easy to administer. Therefore, it is a valid, reliable, and suitable questionnaire for assessing anhedonia among depressed patients in Malaysia.

    The implementation of diversion pouches is to minimise the risk of bacterial contamination as the initial blood flow is prevented from entering primary bag collections as it is diverted into a pouch. This study was carried out to determine the prevalence of bacterial contamination in the diversion pouches used during blood collections in the Transfusion Department of Hospital Seberang Jaya, Penang, Malaysia.

    A cross-sectional prospective study has been conducted on differentiated thyroid cancer (DTC) patients using negative (131)Iodine ((131)I) whole body scans and elevated thyroglobulin (Tg) levels. The main objective of this research was to determine the prevalence of the conversion of differentiated to dedifferentiated thyroid cancer patients during follow up at the Hospital Kuala Lumpur. It has been demonstrated that fluorodeoxyglucose (FDG) uptake is inversely proportional to the iodine concentration and to differentiation of the cells.

    Lemierre's syndrome (LS) is a rare life-threatening infective condition typically starting with an oropharyngeal infection causing thrombophlebitis and metastatic abscesses. The most common aetiology of LS is Fusobacterium necrophorum; however, it can also occur after infection with other organisms. LS mainly affects young healthy adults. The initial infection site can be in the head and neck or in the abdomen. The morbidity rate of this disease is high despite aggressive treatments. In this article, we report a 63-year-old male patient with uncontrolled diabetes mellitus, presenting with Klebsiella pneumoniae infection-induced necrotizing fasciitis on the right side of the neck, leading to LS.

    In an infant presenting with a mass in the abdomen and non-bilious vomiting, duplication cyst needs to be considered in the list of differential diagnoses. Gastric duplication cyst is an uncommon occurrence in children. Diagnosis is based on clinical findings and imaging features. Surgical excision is safe and offers a complete cure. The literature recommends excision even in asymptomatic cases due to isolated reports of malignancy arising in the duplication cyst in later life.

    Obturator hernia is a rare condition that may present in an acute or subacute setting in correlation with the degree of small-bowel obstruction. Pre-operative diagnosis is difficult, as symptoms are often non-specific. A high index of suspicion should be maintained for emaciated elderly women with small-bowel obstruction without a previous abdominal operation and a positive Howship-Romberg sign. When diagnosis is in doubt, computed tomography scan of the abdomen and the pelvis (if available) or laparotomy should be performed immediately, as high mortality rate is related to the perforation of gangrenous bowels. We present 2 cases of strangulated obturator hernia, managed differently with both open and laparoscopic approaches. The diagnostic accuracy of computed tomography scan is highlighted followed by a brief literature review with an emphasis placed on surgical management.

    Pheochromocytoma during pregnancy is potentially disastrous to the mother and fetus. Its ambiguous presentation is often mistaken for pre-eclampsia, although it may imitate other problems during pregnancy. Early diagnosis and timely, appropriate management reduces possible maternal and fetal complications. We identified a case of pheochromocytoma during pregnancy; the condition was initially diagnosed as pre-eclampsia complicated with gestational diabetes. Surgical intervention via left adrenalectomy was successfully performed in the second trimester. After surgery, all of the patient's medical problems nearly subsided and she did not require further treatment. However, her fetus displayed restricted intrauterine growth, and the patient eventually had premature delivery via a caesarean section. A multidisciplinary team to identify and treat pheochromocytoma is mandatory to ensure optimal conditions for tumour removal and to anticipate any possible catastrophic events.

    BACKGROUND: Cocaine- and amphetamine-regulated transcript (CART) is a hypothalamic anorectic neuropeptide that controls feeding behaviour and body weight. The study objective was to investigate the association of the CART prepropeptide gene (CARTPT) rs2239670 variant with obesity and its related anthropometric indicators among patients of a Malaysian health clinic in Kampar, Perak, Malaysia.
    METHODS: A total of 300 Malay/Peninsular Bumiputera, Chinese, and Indian subjects (115 males, 185 females; 163 non-obese, 137 obese) were recruited by convenience sampling, and anthropometric measurements, blood pressures, and pulse rate were taken. Genotyping was performed using AvaII polymerase chain reaction-restriction fragment length polymorphism.
    RESULTS: Genotyping revealed 203 (67.7%), 90 (30.0%), and 7 (2.3%) subjects with the GG, GA, and AA genotypes, respectively, with a minor allele (A) frequency of 0.17. No significant difference in the CARTPT rs2239670 genotype and allele distribution was found between obese and non-obese subjects, and logistic regression showed no association between the mutated genotypes (GA, AA) and allele (A) with obesity, even after adjusting for age, gender, and ethnicity. Furthermore, the measurements did not differ significantly between the genotypes and alleles. No significant difference in the genotype and allele distribution was found among genders, but they were significantly different among ethnicities (P = 0.030 and P = 0.019, respectively).
    CONCLUSION: CARTPT rs2239670 is not a predictor for obesity among the Malaysian subjects in this study.

    Fournier's gangrene is a severe life-threatening infection involving the perianal area, perineum, and external genitalia. It demands prompt recognition, critical care therapy, surgical therapy, and a combination of antibiotics. The infection commonly spreads via the fascial planes and causes superficial vascular thrombosis within the Colles' fascia around the external genitalia. It can extend cephalad to involve the Scarpa's fascia and Camper's fascia in the abdominal wall. The treatment would include multiple debridements, which would result in disfiguring scars of the perineum and might lead to significant physical and psychological complications. We describe a case of a 58-years-old man presenting with Fournier's gangrene resulting from an infection of an impacted urethral stone. The patient previously had obstructive voiding symptoms for 1 month but chose to neglect them. The resultant infection was severe and caused penile and right testicular gangrene. He underwent multiple wound debridements, which included a total penectomy and right orchiectomy. Psychological and rehabilitative support was necessary for him to overcome his loss and disfigurement.

    The study objective was to determine the diagnostic value of physical examinations for positive computer tomography (CT) scans in children with mild head injuries. Retrospective data of patients evaluated for mild head injuries with loss of consciousness (LOC) or amnesia were reviewed. Estimations of prevalence, sensitivity, specificity and predictive values were calculated. Agreement between the physical examinations and CT brain scans was calculated using the Kappa test. 225 patients were included in the study. Of this group, 19.56% of patients had positive CT scans and 7.56% had normal physical examinations. 15 underwent neurosurgical intervention. For positive CT scans, sensitivity and specificity were 61.36% and 60.22%, respectively. Agreement between physical examinations and CT scans was Kappa = 0.147 (P < 0.05), 95% CI (0.035, 0.259). The present study demonstrated that physical examinations were significantly associated with positive CT scans (P = 0.01). However, the calculated Kappa value showed only slight agreement between these 2 variables and the low sensitivity and specificity of the physical examinations suggest that intracranial pathology in children with mild head injuries and LOC or amnesia cannot be excluded based on physical examinations alone.

    Traditionally, the most common diagnostic approach used for diagnosing leptospirosis was the demonstration of immune-seroconversion in acute and convalescent patient serum samples. Recently, a variety of molecular techniques, including conventional and real-time polymerase chain reaction (PCR), have been developed for the specific detection of pathogenic bacteria from the genus Leptospira. PCR is a sensitive, specific, and rapid technique that has been successfully used to detect several microorganisms; including those of clinical significance.
