    Breast masses occur in men far less commonly than women. Papillary lesions of the male breast are rare and comprise a spectrum of lesions ranging from benign intraductal papilloma to intraductal papillary carcinoma and invasive papillary carcinoma. In this case report, a 78-year-old man presented with a subareolar painless mass. Fine needle aspiration cytology (FNAC) was performed. Cytologic examination revealed a cellular aspirate. A diagnosis of papillary lesion favoring papillary carcinoma was rendered. The patient underwent modified radical mastectomy, which showed invasive papillary carcinoma. As far as we know, only a few cases of invasive papillary carcinoma of the male breast have been published in the literature. To the best of our knowledge, this is the first case report of invasive papillary carcinoma of male breast in Malaysia. In this purview, we discuss papillary carcinoma of male breast with review of the relevant literature.

    The Sumatran rhinoceros (Dicerorhinus sumatrensis) is the smallest of all the rhino species. It is one of the rarest mammals in the world and is in imminent danger of extinction. A study was carried out on seven wild-caught females, three wild-caught males and one captive born female Sumatran rhinoceros at the Sumatran Rhinoceros Breeding Centre in Sungai Dusun, Selangor, Malaysia, beginning 1990. As a result of the paucity of scientific information on the reproductive biology of the Sumatran rhinoceros, this study was conducted to obtain information, which could assist in the captive breeding of this endangered and near extinct species. The anatomy of the reproductive system was based on two post-mortem specimens and transrectal real-time ultrasonography in six adult females. Genitalia of the Sumatran rhinoceros were similar to those of other species of rhinoceroses. The cervix consisted of several folds, the uterus was bicornuate with a short body and prominent horns and the ovaries were completely covered by the fimbriated end of the fallopian tube. The internal genitalia could be imaged by ultrasonography. The testes were located within a pendulous scrotum. Two lateral projections were located at the base of the penis. A well-defined process glandis was present at the tip of the penis. The accessory sex glands and the testes could be imaged by ultrasonography.

    The clinical features and management of 12 patients with Fournier's gangrene are described. The patients differed from the usual description of Fournier's gangrene in that they were older, the disease had a less abrupt onset and a definite predisposing factor was identified in 10 of the 12 patients. The importance of early diagnosis and excision of necrotic tissue is emphasized.

    We unveiled the penile penetration mechanics of two earwig species, Echinosoma horridum, whose intromittent organ, termed virga, is extraordinarily long, and E. denticulatum, whose virga is conversely short. We characterised configuration, geometry, material and bending stiffness for both virga and spermatheca. The short virga of E. denticulatum has a material gradient with the stiffer base, whereas the long virga of E. horridum and the spermathecae of both species are homogeneously sclerotised. The long virga of E. horridum has a lower bending stiffness than the spermatheca. The virga of E. denticulatum is overall less flexible than the spermatheca. We compared our results to a previous study on the penetration mechanics of elongated beetle genitalia. Based on the comparison, we hypothesised that the lower stiffness of the male intromittent organ comparing to the corresponding female structure is a universal prerequisite for the penetration mechanics of the elongated intromittent organ in insects.

    BACKGROUND: Male breast cancer (MBC) is usually diagnosed at late stages and therefore has a worse prognosis than female breast cancer (FBC). MBC is also more likely to have lymph node (LN) involvement than FBC.

    MATERIALS AND METHODS: We sought to determine the prognostic role of the examined lymph node (LN), negative LN (NLN), and positive LN counts and the LN ratio (LNR), defined as (positive LNs/ENLs), on the survival rate among MBC patients. We performed a large population-based study using the data from the Surveillance, Epidemiology, and End Results program.

    RESULTS: Older age, black race, stage IV disease, ≤ 1 NLN, and a > 31.3% LNR were significantly associated with worse survival across all prediction models. Moreover, we demonstrated a decreased risk of mortality in MBC patients across the MBC-specific survival model (hazard ratio, 0.98; 95% confidence interval, 0.96-0.998; P = .03) and 10-year MBC-specific survival model (hazard ratio, 0.98; 95% confidence interval, 0.96-0.999; P = .04).

    CONCLUSION: MBC has had an augmented incidence over the years. We found several independent predictors of MBC survival, including age, race, stage, NLNs, and the LNR. We strongly suggest adding the NLN count and/or LNR into the current staging system. Further studies are needed to provide information on the mechanisms underlying the association between the NLN count and MBC survival and the LNR and MBC survival.

    Complete deletions in the AZF (a, b, and c) sub-regions of the Y-chromosome have been shown to contribute to unexplained male infertility. However, the role of partial AZFc deletions in male infertility remains to be verified. Three types of partial AZFc deletions have been identified. They are gr/gr, b1/b3, and b2/b3 deletions. A recent meta-analysis showed that ethnic and geographical factors might contribute to the association of partial AZFc deletions with male infertility. This study analyzed the association of partial AZFc deletions in Malaysian infertile males. Fifty two oligozoospermic infertile males and 63 fertile controls were recruited to this study. Screening for partial AZFc deletions was done using the two sequence-tagged sites approach (SY1291 and SY1191) which were analyzed using both the conventional PCR gel-electrophoresis and the high resolution melt, HRM method. Gr/gr deletions were found in 11.53% of the cases and 9.52% of the controls (p = 0.725). A B2/b3 deletion was found in one of the cases (p = 0.269). No B1/b3 deletions were identified in this study. The results of HRM analysis were consistent with those obtained using the conventional PCR gel-electrophoresis method. The HRM analysis was highly repeatable (95% limit of agreement was -0.0879 to 0.0871 for SY1191 melting temperature readings). In conclusion, our study showed that partial AZFc deletions were not associated with male infertility in Malaysian subjects. HRM analysis was a reliable, repeatable, fast, cost-effective, and semi-automated method which can be used for screening of partial AZFc deletions.

    The case of a 32 year old male with normal male adrenarchal hair pattern, bilateral gynaecomastia, a small phallus, hypospadias and bilateral poorly developed testes presenting with primary infertility secondary to azoospermia and a pelvic cyst is described. Repeated chromosomal analysis showed 46XX chromosomal constitution. Laparotomy revealed a simple cyst between the urinary bladder and the rectum. XX male syndrome is a rare cause of male infertility. The majority of cases is due to interchange of a fragment of the short arm of the Y chromosome containing the region that encodes the testes determining factor with the X chromosome. The presence of a simple cyst in the anatomical location of the uterus to our knowledge has not been reported in the literature.

    The study investigates the use of the various parameters of the semen analysis in predicting the fertility outcome in 82 infertile couples. The sperm density, % progressive motility, % normal morphology were divided into 'normal' and 'abnormal' based on the criteria proposed by WHO. The subsequent cumulative pregnancy rates were then calculated according to this criteria. A life-table method of analysis was used. All female related fertility factors were excluded. With the exception of a sperm density of less than 20 x 10(6) per ml the other parameters showed no significant correlation with the cumulative pregnancy rates at 12 months or 24 months respectively. We concluded that the semen analysis does not predict the probable outcome of the subsequent rates even when female fertility related factors were excluded apart from a sperm density less than 20 x 10(6) per ml.

    In settings where stigma and discrimination toward men who have sex with men (MSM) are high or illegal, like in Malaysia, innovative methods to anonymously reach them are urgently needed. The near ubiquitous availability of mobile technology, including smartphones, has the potential to open new frontiers (such as mHealth) to prevent HIV and other sexually transmitted infections (STIs). The extent to which MSM use mHealth tools for HIV and STI prevention in the Malaysia context, however, is unknown. A cross-sectional online survey in 622 Malaysian MSM was conducted between July and November 2017. Participants were recruited via advertisements on mobile apps frequently used by MSM. In addition to demographic, smartphone access and utilization, and other information were assessed using logistic regression to determine factors associated with the use of a smartphone to search for online sexual health information. Nearly all (99.2%) participants owned a smartphone, with 63% reported having used one to seek sexual health information, including HIV/STIs. Overall, 96% used smartphones to find sexual partners, with high levels of HIV risk behavior reported. Independent correlates of smartphone use to seek online sexual health information included older age (aOR 0.943, p = 0.005), higher education (aOR 2.14, p = 027), recent (past year) HIV testing (aOR 3.91, p = 0.026), and seeking sexual partners using geosocial networking apps (aOR 5.58, p = 0.006). These findings suggest high smartphone use by high-risk MSM to seek sexual health information and suggests that mHealth strategies may be an effective strategy to engage MSM in HIV prevention activities.

    As wild population threats for the endangered false gharial (Tomistoma schlegelii) persist, conservation breeding programs, including developing semen collection techniques for subsequent artificial insemination, are becoming important species conservation measures. Developing reproductive biology understanding of a species is important to developing best practices and hopefully maximizing reproductive successes. However, information on crocodylians functional copulatory anatomy in general is lacking. To that end, zoological facilities and conservation centres have the exceptional opportunity to contribute new understandings that may not otherwise be attainable regarding crocodylian reproductive anatomy, particularly during routine physical examinations or post-mortem necropsies. Therefore, to better understand T. schlegelii reproductive biology, to contribute knowledge in support of zoo breeding conservation efforts and to contribute to what is known overall about crocodylian reproduction, we investigated phallic anatomy of adult male Tomistoma from two zoological populations, the St. Louis Zoo, USA and Sungai Dusun Wildlife Reserve, Peninsular Malaysia. Here, we present the gross anatomical features and histological analysis of underlying tissue-level details in pursuit of a better understanding of copulatory function and associated gamete transfer mechanisms. While much of the overall Tomistoma phallic morphology and inferred function corresponds to that of other crocodylian species and speaks to conserved aspects of functional anatomy across taxa, species-specific aspects of glans and glans tip morphology are also identified. These novelties are discussed in a general function and overall broader evolutionary contexts.

    OBJECTIVES: High rates of syphilis have been reported worldwide among men who have sex with men (MSM). This study aims to describe the clinical pattern and treatment response of syphilis among human immunodeficiency virus (HIV)-infected MSM in Malaysia.

    METHODS: This is a retrospective study on all HIV-infected MSM with syphilis between 2011 and 2015. Data was collected from case notes in five centres namely Hospital Kuala Lumpur, Hospital Sultanah Bahiyah, Hospital Umum Sarawak, University of Malaya Medical Centre and Hospital Sungai Buloh.

    RESULTS: A total of 294 HIV seropositive MSM with the median age of 29 years (range 16-66) were confirmed to have syphilis. Nearly half (47.6%) were in the age group of 20-29 years. About a quarter (24.1%) was previously infected with syphilis. Eighty-three patients (28.2%) had other concomitant sexually transmitted infection with genital warts being the most frequently reported (17%). The number of patients with early and late syphilis in our cohort were almost equal. The median pre-treatment non-treponemal antibody titre (VDRL or RPR) for early syphilis (1:64) was significantly higher than for late syphilis (1:8) (p<0.0001). The median CD4 count and the number of patients with CD4 <200/μl in early syphilis were comparable to late syphilis. Nearly four-fifth (78.9%) received benzathine-penicillin only, 5.8% doxycycline, 1.4% Cpenicillin, 1% procaine penicillin, and 12.4% a combination of the above medications. About 44% received treatment and were lost to follow-up. Among those who completed 1 -year follow-up after treatment, 72.3% responded to treatment (serological non-reactive - 18.2%, four-fold drop in titre - 10.9%; serofast - 43.6%), 8.5% failed treatment and 17% had re-infection. Excluding those who were re-infected, lost to follow-up and died, the rates of treatment failure were 12.1% and 8.8% for early and late syphilis respectively (p=0.582).

    CONCLUSION: The most common stage of syphilis among MSM with HIV was latent syphilis. Overall, about 8.5% failed treatment at 1-year follow-up.

    Objectives To assess the demographic characteristics and outcomes of couples undergoing in vitro fertilisation (IVF) treatment at a private hospital in Al Qassim district, Saudi Arabia. Methods For this retrospective study, information was extracted from the hospital electronic database and IVF unit medical records. Results 2259 couples underwent 2703 IVF/ICSI cycles during 2014 to 2016. The utilization rate was approximately 1000 cycle per million of inhabitants. Mean ages ± standard deviation (SD) for women and men were 32.9 ± 5.7 and 39.2 ± 7.4 years, respectively. More couples were diagnosed with secondary infertility (55.2%) than primary infertility (44.8%). Male factor was the commonest single indication for IVF (36.2%). Mean ± SD infertility duration was 4.70 ± 4.03 years. Overall, 949 couples had a successful pregnancy. Age-specific pregnancy rates (PR) were highest for women <35 years (39.8%) and lowest for women >40 years (11.6%). Male age and infertility duration had no effect on PR but sperm source (fresh vs. frozen) and female age had significant impacts. However, fresh sperm was used in 90.6% cycles whereas frozen sperm was used in 9.4% cycles. Conclusions IVF treatment outcomes in the Al Qassim district are within the boundaries of average international success rates. Infertile couples seeking IVF services should be counselled with regard to important prognostic factors.

    Background: Chemsex is the use of illicit drugs—particularly methamphetamine, gamma hydroxybutyrate (GHB), and gamma-butyrolactone (GBL)—to enhance sexual activity. Chemsex, which occurs primarily among communities of men who have sex with men (MSM), is associated with greater HIV risk behaviors, including multiple sex partners, group sex, condomless sex, and injection drug use. Despite evidence showing chemsex engagement among Malaysian MSM, there is a paucity of research on chemsex among MSM in Malaysia. Methods: This cross-sectional study was conducted through an online survey (August to September 2021) among 870 Malaysian MSM. Participants were recruited through targeted advertisements on social networks. We collected information regarding participants’ recent (<6 months) engagement in chemsex, demographic characteristics, psychosocial factors, pre-exposure prophylaxis (PrEP) knowledge and history, and recent sexual- and drug-related behavior. Multivariable logistic regression was used to identify factors associated with recent (<6 months) chemsex engagement. Results: Just under 1 in 10 (9.0%) of participants reported having engaged in chemsex in the previous six months. More than two-thirds of participants (69.1%) had not disclosed their sexual orientation to anyone in their family and 35.2% reported moderate to severe depressive symptoms. Multivariable analysis found that recent injection drug use (adjusted odds ratio: aOR = 6.61; 95% confidence interval: CI, 2.30−19.03), having shared pre-exposure prophylaxis (PrEP) with someone else (aOR = 5.60; 95% CI, 1.76−17.77), higher perceived HIV risk (aOR = 3.15; 95% CI, 1.25−7.93), knowing someone using PrEP (aOR = 2.93; 95% CI, 1.62−5.31), recent engagement in transactional sex (aOR = 2.38; 95% CI, 1.06−5.39), having a recent STI diagnosis (aOR = 2.36; 95% CI, 1.25−4.44), recent engagement in anal sex (aOR = 2.21; 95% CI, 1.07−4.57), and recent sexual intercourse with an HIV-positive partner (aOR = 2.09; 95% CI, 1.07−4.08) were associated with recent engagement in chemsex. Conclusions: Malaysian MSM who practice chemsex are vulnerable to several HIV risk factors, such as transactional sex, HIV-positive sexual partners, and injection drug use. There is an urgent need for programs that integrate drug, sexual health, and mental health services, with a focus on harm reduction (e.g., condoms, access to and utilization of HIV testing and PrEP services, drug knowledge, and safer drug use) tailored for MSM who practice chemsex.

    BACKGROUND: Depression is the most common psychiatric disorder reported among patients living with Human Immunodeficiency Virus (HIV), resulting from the intricate combination of biological, psychological, and social factors. Biopsychosocial factors can significantly impact the psychological well-being of men who have sex with men (MSM) living with HIV through social stigma, access and compliance to care, economic insecurity, relationship difficulties, and risky behavior. Compared to MSM without HIV, MSM living with HIV were more likely to be depressed. Despite specific vulnerabilities and health needs, MSM living with HIV remain understudied and underserved in Malaysia owing to legal, ethical, and social challenges.

    OBJECTIVE: This is merely a published protocol, not the findings of a future study. This study aims to determine and explain the predictors of depressive symptoms among MSM living with HIV. Specifically, this study wants to determine the association between depressive symptoms among MSM living with HIV and biological, psychosocial, and social factors. Finally, the mixed methods will answer to what extent the qualitative results confirm the quantitative results of the predictors of depressive symptoms among MSM living with HIV.

    METHODS: The study has ethical approval from the Medical Research Ethics Committee (MREC) of the Ministry of Health (MOH) NMRR ID-21-02210-MIT. This study will apply an explanatory sequential mixed methods study design. It comprised two distinct phases: quantitative and qualitative study design for answering the research questions and hypothesis. This study will randomly recruit 941 MSM living with HIV in the quantitative phase, and at least 20 MSM living with HIV purposively will be selected in the qualitative phase. The study will be conducted in ten public Primary Care Clinics in Selangor, Malaysia. A self-administered questionnaire will gather the MSM's background and social, psychological, and biological factors that could be associated with depressive symptoms. For the quantitative study, descriptive analysis and simple logistic regression will be used for data analysis. Then, variables with a P value < 0.25 will be included in multiple logistic regression to measure the predictors of depressive symptoms. In the qualitative data collection, in-depth interviews will be conducted among those with moderate to severe depressive symptoms from the quantitative phase. The thematic analysis will be used for data analysis in the qualitative phase. Integration occurs at study design, method level, and later during interpretation and report writing.

    RESULT: The quantitative phase was conducted between March 2022 to February 2023, while qualitative data collection is from March 2023 to April 2023, with baseline results anticipated in June 2023.

    CONCLUSION: In combination, qualitative and quantitative research provides a better understanding of depressive symptoms among MSM living with HIV. The result could guide us to provide a comprehensive mental healthcare program toward Ending the AIDS epidemic by 2030.
