Aim: The classic variants in superior articular facets of atlas such as, variability in shape, presence of notch, constrictions, partial or complete separation of facets, and presence of pressure facets, have been reported to a limited extent in relation to ergonomics of cranio-vertebral joint. Objective: The objectives of the present study were to report the analyzed morphological features and metrical values of superior articular facets of the atlas. The morphological features which were included in this study were variability in shapes, constrictions and partial or complete separation of facets. The metrical measure included the surface area measurement of the facets. Material and Methods: This study was carried out on 50 (100 sides) dry atlas vertebrae from the Department of Anatomy, St John's Medical College, Bangalore, India. The superior articular facets were studied for the shape and symmetry, constrictions and partial or complete separation of facets. The surface area of the facets were measured by using IMAGEJ (Image processing and analysis in JAVA) tool, that was primarily designed to measure and analyze different metrics. Results: The mean surface area on the right side was 157.3 ± 29.02, and on the left side, it was 158.5 ± 24.85. Oval, irregular, kidney and figure of eight shapes were observed either on both sides or on one side. Bilateral constrictions of facets were seen in 58% of vertebrae. Bilateral, complete separations of facets were seen in 30% of vertebrae Conclusion: The observations of the present study are important to understand the ergonomics of the cranio-vertebral joint and they are helpful for academicians, neuro-surgeons, clinicians and radiologists in day to day clinical practice.

Objectives: This study aimed to assess the level of knowledge of oral cancer and its associated factors among university students in Malaysia. Methods: A cross sectional study was conducted among 200 university students in Malaysia. A self administered questionnaire was used to collect data. It included questions on socio-demographic data, awareness and knowledge of oral cancer. Results: Mean age of the respondents was 21.5±2.5 and the age ranged from 18 to 27 years. The majority of the respondents were aware of oral cancer (92.0%) and recognized the followings as signs and symptoms of oral cancer: ulcer and oral bleeding (71.0%), followed by swelling (61.5%). A satisfactory knowledge was observed on the following risk factors; smoking (95.5%), poor oral hygiene (90.5%), family history (90.0%), alcohol (84.5%) and poor fitting dentures (83.0%). However, unsatisfactory knowledge was observed about hot/spicy food (46.5%), obesity (36.0%), old age (31.5%), dietary factor (29.0%) and smokeless tobacco (25.5%). Knowledge of oral cancer was associated significantly with age (p<0.01), year of study (p<0.01) and course of study (p<0.01). Conclusion: Instead of satisfactory awareness and knowledge of oral cancer and its clinical presentations, inadequate knowledge was observed about its risk factors. There is a need to introduce oral cancer education among university students.

Goniothalamin, a natural compound extracted from Goniothalamus sp. belonging to the Annonacae family, possesses anticancer properties towards several tumor cell lines. This study focused on apoptosis induction by goniothalamin (GTN) in the Hela cervical cancer cell line. Cell growth inhibition was measured by MTT assay and the IC50 value of goniothalamin was 3.2±0.72 μg/ml. Morphological changes and biochemical processes associated with apoptosis were evident on phase contrast microscopy and fluorescence microscopy. DNA fragmentation, DNA damage, caspase-9 activation and a large increase in the sub-G1 and S cell cycle phases confirmed the occurrence of apoptosis in a time-dependent manner. It could be concluded that goniothalamin show a promising cytotoxicity effect against cervical cancer cells (Hela) and the cell death mode induced by goniothalamin was apoptosis.

Dengue fever is a major public health problem in Malaysia. This study aimed to assess factors affecting knowledge, attitudes, and practices regarding dengue fever among a selected population in Malaysia. A descriptive, community-based, cross sectional study was conducted with 300 participants from three different geographical settings in urban, semi-urban, and rural areas within the states of Selangor and Kuala Lumpur. The questionnaire included questions on demographic data, knowledge, attitudes, and practices regarding dengue fever. Mean age of respondents was 34.4 (± 5.7) years, and the age ranged from 18 to 65 years. The majority of respondents were married (54.7%), Malays (72.7%) and heard about dengue fever (89.7%). Television was the common source of information about dengue fever (97.0%). Participants answered 4 out of 15 items of knowledge incorrectly. There was no significant association between knowledge score and socio-demographic factors. About one-fifth of the respondents (24%) believed that immediate treatment is not necessary for dengue fever, and the majority of them were not afraid of the disease (96.0%). Attitudes toward dengue fever were significantly associated with the level of education and employment status (p<0.05). Practice was associated significantly with age, marital status, and geographic area (p<0.05) and knowledge on dengue fever (p=0.030). There is a need to increase health promotion activities through campaigns and social mobilization to increase knowledge regarding dengue fever. This would help to mold positive attitudes and cultivate better preventive practices among the public to eliminate dengue in the country.

Background :Accidental needle-stick injuries (NSIs) are a hazard for health-care workers and general public health. Orthopaedic surgeons may be more prone to NSIs due to the prevalence of bone spikes in the operative field and the use of sharp orthopaedic instruments such as drills, saws and wires. A hospital-based cross sectional study was conducted in the orthopedic wards of Melaka General Hospital. The prevalence of NSIs was 32 (20.9%) and majority of it occurred during assisting in operation theatre 13(37.4%). Among them six (18.8%) were specialist, 12(37.5%) medical officer, 10 (31.2%) house officer and four staff nurses (12.5%). Among the respondents 142 (92.8%) had been immunized against Hepatitis B and 148 (96.7%) participants had knowledge regarding universal precaution. The incidence of NSI among health care workers at orthopaedics ward was not any higher in comparison with the similar studies and it was found out that the prevalence was more in junior doctors compared with specialist and staff nurses and it was statistically significant.Needle sticks injury, health care workers, and standard precaution.

During the routine dissection, a rare anomaly was observed in left lower limb of a female cadaver. The external iliac artery continued as femoral artery, branched on lateral side as the lateral circumflex femoral artery and on medial side as profunda femoris artery. On tracing the lateral circumflex femoral artery, the ascending branch towards the spinous anastomosis was very thin and coursed behind the rectus femoris muscle. The transverse and descending branches were not observed, however, the artery coursed along the vastus lateralis towards the knee. The femoral artery had its normal course and continued as popliteal artery. The profunda femoris artery originated from the medial side of the external iliac artery, initially superficial to the femoral vein, coursed downwards and posteriorly, relating posteromedial to femoral artery. The medial circumflex femoral artery originated as thin branch, which further divided into two divisions. The profunda femoris gave origin of 3 perforators and continued as 4th perforator. The unusual branching pattern was observed to be novel and not reported in the literature.

Klinefelter syndrome phenotype is associated with hypogonadism and infertility that results from 47,XXY or 46,XY/47,XXY karyotype. Men with mosaic status show milder phenotype than those of non-mosaics. The present study aimed to report, a data profile on the observed phenotypic features in 72 cytogenetically confirmed Klinefelter syndrome male gathered from duly filled proforma. The reported phenotype from the literature were categorized into 14 groups (highly arched palate, winged scapula, thin long fingers, flat feet, prognathism, liver cirrohsis, seizures, mental illness, penis, gonads, axillary hair growth, and pubic hair growth, presence of gynaecomastia and semen analysis). The calculated total number of the 14 features multiplied for the 72 samples was 1,008. Of the 1,008 features (14X72), KFS male manifested only 16.56% of abnormal features (167/1,008). Scanty axillary hair growth (25%, 18), scanty pubic hair growth (26.38%, 19), small sized penis (25%, 18), small sized gonads (55.56%, 40), presence of gynaecomastia (45.83%, 33) were of highest percentage. It was noticed that, for the entire sample of 72, the manifestation of the 14 categorised features was only 16.56%, irrespective of the karyotype; out of which, with 47,XXY, the manifestation of the phenotypic features was observed to be highest (18.52%, 153/ 826). The findings confirmed the reported observations that in Klinefelter syndrome, there seemed to be a wide variability in the phenotype. © Kamla-Raj 2012.

Low back pain is a common musculoskeletal symptom in pregnancy that can present as lumbar pain or pelvic girdle pain, with significant physical and psychosocial implications. Pelvic girdle pain is more prevalent and results in greater disability than lumbar pain. It is possible to distinguish between these two conditions from a detailed history based on the site of the pain, its intensity, disability and pain provocation tests. Management of low back pain in pregnancy is conservative, with physical exercise for lumbar pain and minimising activities that exacerbate pain, analgesics and bed rest for pelvic girdle pain, as well as avoiding abduction beyond the pain-free zone in labour. There is evidence that stabilising exercises in patients with pelvic girdle pain postpartum have a beneficial effect. Other treatment modalities that have been shown to be safe and effective include pelvic belts, transcutaneous electrical nerve stimulation, spinal manipulative therapy, acupuncture and complementary therapy with yoga. Other orthopaedic complications in pregnancy such as carpal tunnel syndrome, pubic symphysis rupture, transient osteoporosis and osteonecrosis are usually selflimiting with a satisfactory outcome. However, a lack of awareness and failure to recognise these complications can result in long-term morbidity. Knowledge of the preoperative diagnostic investigations, surgical approaches and intraoperative positioning of the mother to avoid gravid uterus compression is vital in orthopaedic emergencies such as lumbar disc herniation, cauda equina syndrome, fractures and acute compartment syndrome of the lower limb to ensure a safe maternal and fetal outcome and to prevent serious disability. Pregnancy is not contraindicated in women with preexisting orthopaedic complications such as kyphoscoliosis and total hip arthroplasty as there is no evidence to suggest increased maternal or fetal risks. severe debilitating pain. The pain can adversely affect the quality of life, affect sick leave and predispose to chronic pain syndrome.2 There is evidence that an increasing number of women are requesting elective delivery by induction or caesarean section to achieve symptomatic relief. Such complications and delivery options increase the risk to the mother and the fetus, with significant resource implications.3 4 In addition, lifethreatening complications in pregnancy such as venous thromboembolism are reported to be related to ambulatory difficulties during acute episodes of pain.5 There is, however, insufficient knowledge about the management strategies due to fear of possible harm to the fetus resulting from the effects of treatment. 4 This paper reviews the terminology, epidemiology, pathophysiology, diagnostic approaches and evidence-based modern management of the common musculoskeletal symptoms, orthopaedic complications and pregnancy outcomes in the presence of pre-existing orthopaedic conditions in pregnancy.

Introduction: Methadone has long been regarded as an effective treatment for opioid dependence. However, many patients discontinue maintenance therapy because of its side effects, with one of the most common being sexual dysfunction. Buprenorphine is a proven alternative to methadone. This study aimed to investigate sexual dysfunction in opioid-dependent men on buprenorphine maintenance treatment (BMT) and methadone maintenance treatment (MMT). The secondary aim was to investigate the correlation between sexual dysfunction and the quality of life in these patients. Methods: Two hundred thirty-eight men participated in this cross-sectional study. Four questionnaires were used, the Mini International Neuropsychiatric Interview, Opiate Treatment Index, Malay version of the International Index of Erectile Function 15 (Mal-IIEF-15), and World Health Organization Quality of Life-BREF Scale. Multivariate analysis of covariance was used to examine the relationship between MMT and BMT and the Mal-IIEF 15 scores while controlling for all the possible confounders. Results: The study population consisted of 171 patients (71.8%) on MMT and 67 (28.2%) on BMT. Patients in the MMT group who had a sexual partner scored significantly lower in the sexual desire domain (p < 0.012) and overall satisfaction (p = 0.043) domain compared with their counterparts in the BMT group. Similarly, patients in the MMT group without a sexual partner scored significantly lower in the orgasmic function domain (p = 0.008) compared with those in the BMT group without a partner. Intercourse satisfaction (p = 0.026) and overall satisfaction (p = 0.039) were significantly associated with the social relationships domain after adjusting for significantly correlated sociodemographic variables. Conclusions: Sexual functioning is critical for improving the quality of life in patients in an opioid rehabilitation program. Our study showed that buprenorphine causes less sexual dysfunction than methadone. Thus, clinicians may consider the former when treating heroin dependents who have concerns about sexual function. © 2016 Yee et al.
