    IMPORTANCE: The limited data on cancer phenotypes in men with germline BRCA1 and BRCA2 pathogenic variants (PVs) have hampered the development of evidence-based recommendations for early cancer detection and risk reduction in this population.

    OBJECTIVE: To compare the cancer spectrum and frequencies between male BRCA1 and BRCA2 PV carriers.

    DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 6902 men, including 3651 BRCA1 and 3251 BRCA2 PV carriers, older than 18 years recruited from cancer genetics clinics from 1966 to 2017 by 53 study groups in 33 countries worldwide collaborating through the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). Clinical data and pathologic characteristics were collected.

    MAIN OUTCOMES AND MEASURES: BRCA1/2 status was the outcome in a logistic regression, and cancer diagnoses were the independent predictors. All odds ratios (ORs) were adjusted for age, country of origin, and calendar year of the first interview.

    RESULTS: Among the 6902 men in the study (median [range] age, 51.6 [18-100] years), 1634 cancers were diagnosed in 1376 men (19.9%), the majority (922 of 1,376 [67%]) being BRCA2 PV carriers. Being affected by any cancer was associated with a higher probability of being a BRCA2, rather than a BRCA1, PV carrier (OR, 3.23; 95% CI, 2.81-3.70; P

    Melorheostosis is a rare, progressive bone disease accompanied by hyperostosis and soft tissue fibrosis. While affected adults present with contracture and pain, children present with limb length discrepancy and deformity. We report the case of a 20-year-old woman with melorheostosis since childhood who presented with right hand deformity and numbness. Radiographs showed not only a combination of dense sclerosis and opacities, but also the classic 'flowing candle wax' appearance. Radiography can be used to identify melorheostosis, thus preventing unnecessary bone biopsies. Carpal tunnel release revealed the presence of a thickened flexor retinaculum and a degenerated median nerve distal to the retinaculum, but did not show hyperostosis. This case highlights the role of nerve decompression in melorheostosis and the importance of early identification of the disease to prevent unnecessary bone biopsies.

    INTRODUCTION: Cephalic index (CI), the ratio of head breadth to head length, is widely used to categorise human populations. The aim of this study was to access the impact of anthropometric measurements on the CI of male Japanese university students.

    METHODS: This study included 1,215 male university students from Tokyo and Kyoto, selected using convenient sampling. Multiple regression analysis was used to determine the effect of anthropometric measurements on CI.

    RESULTS: The variance inflation factor (VIF) showed no evidence of a multicollinearity problem among independent variables. The coefficients of the regression line demonstrated a significant positive relationship between CI and minimum frontal breadth (p < 0.01), bizygomatic breadth (p < 0.01) and head height (p < 0.05), and a negative relationship between CI and morphological facial height (p < 0.01) and head circumference (p < 0.01). Moreover, the coefficient and odds ratio of logistic regression analysis showed a greater likelihood for minimum frontal breadth (p < 0.01) and bizygomatic breadth (p < 0.01) to predict round-headedness, and morphological facial height (p < 0.05) and head circumference (p < 0.01) to predict long-headedness. Stepwise regression analysis revealed bizygomatic breadth, head circumference, minimum frontal breadth, head height and morphological facial height to be the best predictor craniofacial measurements with respect to CI.

    CONCLUSION: The results suggest that most of the variables considered in this study appear to influence the CI of adult male Japanese students.

    INTRODUCTION: This study aimed to investigate the determinants of sexual intercourse initiation among incarcerated adolescents aged 12-19 years in Malaysia.

    METHODS: This was a sequential mixed-method research project that was conducted in two phases. Quantitative and qualitative methods were used in the first and second phases, respectively. Data was collected via a survey using self-reported questionnaires from 1,082 adolescents, and from in-depth interviews and the written essays of 29 participants. The participants were recruited from 22 welfare institutions in peninsular Malaysia.

    RESULTS: Among the study participants, 483 were male and 599 were female. Overall, 62.3% of the incarcerated adolescents had initiated sexual intercourse at least once. The mean age at first sexual intercourse for both genders was 14.0 years. Individual factors found to be associated with previous sexual intercourse were the female gender (odds ratio [OR] 1.75; 95% confidence interval [CI] 1.11-2.74), previous alcohol use (OR 1.80; 95% CI 1.10-2.94), previous illicit drug use (OR 1.85; 95% CI 1.07-3.22), permissive attitude toward premarital sex (OR 4.34; 95% CI 2.17-8.70), and sexual abuse during childhood (OR 5.41; 95% CI 3.52-8.32). Qualitative findings revealed that the reasons for initiation of sexual intercourse among these adolescents were partner influence, inability to control sex drive, family issues, and the perception of sex as an expression of love.

    CONCLUSION: The determinants of sexual intercourse initiation among incarcerated Malaysian adolescents are comparable to those of developed countries. However, in Malaysia, sexual and reproductive health programmes for such adolescents should be tailored to address their specific needs.

    INTRODUCTION: Foot pain is a common problem, especially in women, and studies have shown that it is related to footwear. This study was conducted to establish the prevalence of nontraumatic foot pain and its contributing factors in young working Malaysian women in an urban setting.

    METHODS: The survey was conducted on a group of working women (age range 21-40 years) selected using convenience sampling. Data on foot problems was collected through an investigator-directed questionnaire and during clinical inspection of the foot.

    RESULTS: A total of 400 women, with a mean age of 29.4 years, were recruited. Half (n = 200) of the women had experienced recurrent nontraumatic foot pain in the past one year. Subjective assessments of foot pain using the Numeric Intensity Scale gave an average score of 4.89 ± 1.78 (range 2-10), with most episodes occurring at the heel. There was no statistically significant association between foot pain and age, ethnicity or body mass index. However, there was a higher incidence of foot pain in women wearing high-heeled footwear than those wearing non-high-heeled footwear (p = 0.027, odds ratio 1.591).

    CONCLUSION: Nontraumatic foot pain is common among young working women in our society. More than half (68.4%) of the women with foot pain in our study attributed the pain to footwear. Wearing high-heeled shoes to work was a significant contributing factor. Increased public awareness on the importance of proper footwear may help to reduce the prevalence of nontraumatic foot pain in working women.

    INTRODUCTION: The increased prevalence of metabolic syndrome worldwide is closely related to the rising obesity epidemic. The objectives of the study were to determine the prevalence and identify the associated and prognostic factors that influence the risk of metabolic syndrome among obese patients attending the Obesity Clinic at Hospital Universiti Sains Malaysia.
    METHODS: A study was conducted involving 102 obese persons who attended the Obesity Clinic from January 1 to December 31, 2005. Metabolic syndrome was defined according to the International Diabetes Federation criteria.
    RESULTS: The overall prevalence of metabolic syndrome among obese patients was 40.2 percent. The prevalence was higher in females (43.7 percent) than in males (32.3 percent). The prevalence of metabolic syndrome was noted to increase with increasing body mass index class, from class 1 to class 2. However, the prevalence was lower in obesity class 3. The prevalence of metabolic comorbidities of raised blood pressure, reduced high density lipoprotein, high triglyceride and raised fasting blood glucose was 42, 40, 36 and 17 percent, respectively. A quarter of obese patients in this study had no other comorbidity. Based on logistic regression multivariable analysis, age was the only significant associated factor that influenced the risk of having metabolic syndrome.
    CONCLUSION: The prevalence of metabolic syndrome was high and the highest comorbidity was high blood pressure. Age was the only significant risk factor of having this syndrome.

    INTRODUCTION: This study was undertaken to establish the craniofacial anthropometric norms of young adult Malaysian Malays.
    METHODS: The study group consisted of convenient samples of 100 healthy volunteers (aged 18-25 years), with an equal number of female and male subjects who had no history of mixed racial parentage. 22 linear measurements were taken twice from 22 landmarks over six craniofacial regions.
    RESULTS: The Malays shared many similar sizes of measurements with the Singaporean Chinese. Their left eye fissure length and mouth width (ch-ch) were almost identical for both genders. However, Malay females had an upper lip height (sn-sto) (left) and ear width (pra-pa) similar to Singaporean Chinese females. Six other measurements, viz. the head width (eu-eu), head circumference (on-op), face height (n-gn), lower face height (sn-gn), (left) eye fissure height (ps-pi), cutaneous upper lip height (sn-ls) and cutaneous upper lip height (ls-sto), were 0.4-4.3 mm less in the Malays. Measurements for another four parameters, viz. the length of the head (g-op), biocular width (ex-ex), lower vermillion height (sto-li) and (left) ear length (sa-sba), were 0.5-3.6 mm higher in the Malays. Only three measurements were obviously different; the height of the head (v-n) and intercanthal width (en-en), were lower, and the protrusion of the nasal tip (sn-prn) was higher in the Malays.
    CONCLUSION: These findings suggest that three features, i.e. the height of the head (v-n), intercanthal width (en-en) and protrusion of the nasal tip (sn-prn) may be useful in differentiating a Malay face from a Singaporean Chinese one.

    INTRODUCTION: Metacognition is a cognitive debiasing strategy that clinicians can use to deliberately detach themselves from the immediate context of a clinical decision, which allows them to reflect upon the thinking process. However, cognitive debiasing strategies are often most needed when the clinician cannot afford the time to use them. A mnemonic checklist known as TWED (T = threat, W = what else, E = evidence and D = dispositional factors) was recently created to facilitate metacognition. This study explores the hypothesis that the TWED checklist improves the ability of medical students to make better clinical decisions.

    METHODS: Two groups of final-year medical students from Universiti Sains Malaysia, Malaysia, were recruited to participate in this quasi-experimental study. The intervention group (n = 21) received educational intervention that introduced the TWED checklist, while the control group (n = 19) received a tutorial on basic electrocardiography. Post-intervention, both groups received a similar assessment on clinical decision-making based on five case scenarios.

    RESULTS: The mean score of the intervention group was significantly higher than that of the control group (18.50 ± 4.45 marks vs. 12.50 ± 2.84 marks, p < 0.001). In three of the five case scenarios, students in the intervention group obtained higher scores than those in the control group.

    CONCLUSION: The results of this study support the use of the TWED checklist to facilitate metacognition in clinical decision-making.

    Granular cell tumours (GrCTs) are uncommon soft tissue tumours that are usually benign (approximately 0.5%-2.0% have been reported as malignant). They are very rarely found at the extremities. Differentiating a malignant GrCT from a benign one is important as the former is aggressive and has a poor prognosis, whereas the latter, after surgical resection, has excellent outcomes. A malignant lesion can be suspected on clinical presentation and confirmed via histopathological examination using the Fanburg-Smith criteria.

    INTRODUCTION: The present study aimed to obtain preliminary tympanometric data of young Malay adults and to compare the results between genders.
    METHODS: 96 undergraduate students (49 males and 47 females), aged 19-25 (mean and standard deviation 21.14 +/- 1.31) years, participated in this study. Otoscopic examination, pure tone audiometry, qualitative tympanogram and ipsilateral acoustic reflex were measured to ensure a clear ear canal, normal hearing and normal middle ear function, prior to tympanometric measurement. As a result, a total of 154 ears (80 ears from males and 74 ears from females) were selected for further statistical analyses. The tympanometric parameters measured were peak compensated static acoustic admittance (Peak Y(tm)), tympanometric width (TW) and equivalent ear canal volume (V(ea)).
    RESULTS: The results showed that the mean Peak Y(tm), V(ea) and TW for males were 0.81 mmhos, 1.48 cubic cm and 113.67 daPa, respectively. The mean Peak Y(tm), V(ea) and TW for females were 0.63 mmhos, 1.12 cubic cm and 98.04 daPa, respectively. Males were found to have significantly higher mean V(ea) and mean Peak Y(tm) than females. However no significant gender difference was observed in the mean TW.
    CONCLUSION: The current study suggests that young Malay adults may require gender-specific Peak Y(tm) and V(ea) values when implementing a quantitative approach in tympanogram interpretation.

    INTRODUCTION: Diabetic retinopathy (DR) is the commonest complication of diabetes mellitus (DM), and is the leading cause of blindness among working adults. Modification of the associated risk factors as well as early detection and treatment of sight-threatening DR can prevent blindness. Clinical practice guidelines recommend annual eye screening for patients with DM. The proportion of patients in Malaysia who adhere to this recommendation was initially unknown.
    METHODS: The Malaysian National Health and Morbidity Survey is a population-based survey conducted once every decade on the various aspects of health, behaviour and diseases. The DM questionnaire on eye screening was administered as face-to-face interviews with 2,373 patients with known DM who were aged 18 years and older.
    RESULTS: In all, 55 percent of patients with known DM had never undergone an eye examination. Among patients who had undergone eye examinations, 32.8 percent had the last examination within the last one year, 49.8 percent within the last one to two years, and 17.4 percent more than two years ago. A significantly lower proportion of younger patients and patients who received treatment for DM from non-government facilities had previously undergone eye examinations.
    CONCLUSION: The prevalence of DM observed among Malaysians aged 30 and above is 14.9 percent; thus, there is a significant number of people with potential blinding DR. Adherence to eye screening guidelines and the prompt referral of sight-threatening DR are essential in order to reduce the incidence of blindness among patients with DM.

    INTRODUCTION: This study aimed to compare the quality of life based on the Short Form-36 (SF-36) between two different groups of type 2 diabetes mellitus patients with glycaemic control: those with a glycosylated haemoglobin (HbA1c) level at or below 7.5 percent and those above 7.5 percent.
    METHODS: In this cross-sectional study, a generic SF-36 questionnaire was self-administered to patients with type 2 diabetes mellitus. Based on the HbA1c level, the mean SF-36 scale scores were compared. The analysis of covariance was used to obtain the adjusted mean scores of the SF-36 scales while controlling for age and duration of type 2 diabetes mellitus.
    RESULTS: 150 patients with type 2 diabetes mellitus were analysed. There were 63 (42 percent) women and 87 (58 percent) men, and their mean HbA1c level was 8.9 percent (SD 2.4 percent). When comparing the two groups of patients with different HbA1c levels, the adjusted means of four scales: physical health functioning, general health, social functioning and mental health, differed significantly between the two. The SF-36 scale scores in type 2 diabetes mellitus patients were also lower than those of the SF-36 norms for the Malaysian population.
    CONCLUSION: Type 2 diabetes mellitus patients with poor glycaemic control had lower mean SF-36 scores in physical functioning, general health, social functioning and mental health, and the SF-36 scores in these patients were also lower than the SF-36 norms of the Malaysian population.

    INTRODUCTION: Erectile dysfunction (ED) is a serious global burden that affects men as well as their partners. This study aimed to determine the prevalence and predictors of ED among male outpatient clinic attendees in Johor, Malaysia.

    METHODS: We conducted a cross-sectional study of Malaysian men aged ≥ 18 years attending two major outpatient clinics in Johor Bahru and Segamat in Johor, Malaysia, between 1 January 2016 and 31 March 2016. Subjects were chosen via simple random sampling and 400 patients were recruited. The study instrument was a survey form that consisted of three sections: sociodemographic and comorbid profile, validated English and Malay versions of the 15-item International Index of Erectile Function, and the 21-item Depression Anxiety Stress Scale.

    RESULTS: The overall prevalence of self-reported ED was 81.5%. The prevalence of ED according to severity was as follows: mild (17.0%), mild to moderate (23.8%), moderate (11.3%) and severe (29.5%). Multivariate analysis showed that ED was associated with increasing age (odds ratio [OR] 4.023, 95% confidence interval [CI] 1.633-9.913), Indian as compared to Malay ethnicity (OR 3.252, 95% CI 1.280-8.262), secondary as compared to tertiary education (OR 2.171, 95% CI 1.203-3.919), single as compared to married status (OR 6.119, 95% CI 2.542-14.734) and stress (OR 4.259, 95% CI 1.793-10.114).

    CONCLUSION: ED has significant prevalence and severity among adult male outpatient clinic attendees in Johor. Increasing age, Indian ethnicity, lower educational level, singlehood and stress were significant predictors of ED.

    INTRODUCTION: This study explored attitudes towards vasectomy and its acceptance as a method of contraception among clinical-year medical students, and determined the association between their demographic characteristics, and attitudes and acceptance.

    METHODS: A cross-sectional survey was conducted among clinical-year medical students from a Malaysian private medical college using a self-administered questionnaire.

    RESULTS: There were 330 participants with a female preponderance and a mean age of 22.0 ± 1.1 years. The largest proportion of respondents were from Year 3. The vast majority were ethnically Malay (91.8%) and followed Islam (92.4%). Overall, 60.9% of participants had a positive attitude towards vasectomy and 76.0% showed good acceptance. Gender, academic year, ethnicity and religion variables were not associated with attitudes and acceptance (p > 0.05). A significantly higher proportion of male respondents thought that vasectomy was religiously forbidden and would give a bad impression. A significantly higher proportion of Year 5 students agreed to the statement 'I would recommend vasectomy to relatives, friends and people close to me' compared to Year 3 and 4 students.

    CONCLUSION: Students' perception of vasectomy as a contraceptive method was encouraging. Our results suggest that their knowledge improved as medical training progressed, and attitudes evolved for the better irrespective of their traditional, cultural and religious beliefs - highlighting the importance of providing students with evidence-based learning about male sterilisation, which is more cost-effective and is associated with lower morbidity than female sterilisation. A qualitative study involving students from different ethnicities and religions would provide a better understanding of this subject.

    INTRODUCTION: Many older people rely on caregivers for support. Caring for older people can pose significant burdens for caregivers yet may also have positive effects. This study aimed to assess the impact on the caregivers and to determine factors associated with caregivers who were burdened.

    METHODS: This was a cross-sectional study of 385 caregivers of older people who attended a community clinic in Malaysia. Convenience sampling was employed during the study period on caregivers who were aged ≥ 21 years and provided ≥ 4 hours of unpaid support per week. Participants were asked to complete a self-administered questionnaire, which included the Carers of Older People in Europe (COPE) index and the EASYCare Standard 2010 independence score. The COPE index was used to assess the impact of caregiving. A highly burdened caregiver was defined as one whose scores for all three COPE subscales were positive for burden. Care recipients' independence was assessed using the independence score of the EASYCare Standard 2010 questionnaire. Multiple logistic regression was used to determine the factors associated with caregiver burden.

    RESULTS: 73 (19.0%) caregivers were burdened, of whom two were highly burdened. Caregivers' median scores on the positive value, negative impact and quality of support scales were 13.0, 9.0 and 12.0, respectively. Care recipients' median independence score was 18.0. Ethnicity and education levels were found to be associated with caregiver burden.

    CONCLUSION: Most caregivers gained satisfaction and felt supported in caregiving. Ethnicity and education level were associated with a caregiver being burdened.

    A doctor's attire is important in making a positive first impression and enhancing the overall healthcare experience for patients. We conducted a study to examine the perceptions and preferences of patients and doctors regarding six types of dress codes used by doctors in different scenarios and locations. A total of 87 patients and 46 doctors participated in the study. Separate sets of questionnaires containing four demographic questions and 14 survey questions were distributed to the two groups. Most patients preferred doctors to dress formally in white coats regardless of the scenario or location, whereas the majority of doctors preferred formal attire without white coats. Both groups preferred operating theatre attire in the emergency department. Our findings confirmed that patients perceived doctors in white coats to be more trustworthy, responsible, authoritative, confident, knowledgeable and caring. There is a need to educate the public about the reasons for changes in doctors' traditional dress codes.
