    Naevus sebaceus is a cutaneous hamartoma with the potential of developing into benign or malignant neoplasms. Syringocystadenoma papilliferum (SCAP) have been reported to originate from naevus sebaceus. SCAP is a rare, benign adnexal skin tumour of apocrine or eccrine type of differentiation which typically presents as a nodule or a plaque on the scalp or face. We report a case of syringocystadenoma papilliferum arising in an undiagnosed pre-existing naevus sebaceus in a 56-year-old female.

    Thyroid carcinoma is uncommon. Papillary thyroid carcinoma (PTC) represents the majority of differentiated thyroid carcinoma and is a recognised complication of prior exposure to ionizing radiation. Even more uncommon is the synchronous occurrence of PTC with Hodgkin lymphoma (HL) as multiple primary malignancies. We report a 33-year-old mother of three who developed asymptomatic thyroid nodule for four years, and neck swelling for the recent ten months. She denied constitutional symptoms or B symptoms, and thyroid profiles were normal. Initially, metastatic thyroid cancer was suspected based on ultrasound scan findings of enlarged left thyroid gland and enlarged supraclavicular lymph nodes (LN). However, fine needle aspiration examinations of the thyroid nodule were inconclusive, and the supraclavicular LN was suspicious of HL. Computerised tomography scan detected a large mass at the thyroid glands and lymphadenopathies in the mediastinal, hilar, subcarinal and axilla with dimensions up to 6 cm. Left hemi-thyroidectomy with left supraclavicular LN biopsy revealed PTC in the left thyroid lobe measuring 38 x 25 x 18 mm, and the left supraclavicular LN was not definitive of HL. Completion thyroidectomy on the right side, bilateral central neck dissection and excision biopsy of the right supraclavicular LN revealed the presence of HL in the right supraclavicular LN, and both HL and metastatic PTC in right central LN. After multidisciplinary discussions, the patient received chemotherapy at four weeks postoperatively and achieved complete remission. This report highlights the importance of patient-centered approach and multidisciplinary consensus within lack of established guidelines, given rarity of the case.

    Papillary thyroid carcinoma (PTC) is the most common thyroid carcinoma and is derived from thyroid follicular cells. In contrast, medullary thyroid carcinoma (MTC) is rare and originates from the parafollicular C-cells. Synchronous occurrence of these two carcinomas is uncommon and occurs as either discrete lesions or as a mixed lesion. The current case report describes a 50-year-old woman with synchronous multiple discrete MTC and PTC with lymph nodes metastasis. Pathologists and treating physicians should be aware of the synchronous coexistence of these entities to avoid possible misdiagnosis.

    INTRODUCTION: The susceptibility patterns of anaerobes are becoming less predictable due to the emergence of anaerobic resistance trends to antibiotics; hence increasing the importance of the isolation and antimicrobial susceptibility testing of anaerobes.

    MATERIALS AND METHODS: This study investigated the isolation of anaerobes from the clinical specimens of Hospital Sungai Buloh, Malaysia, from January 2015 to December 2015. All isolates were identified using the API 20A system (bioMérieux, France). Antimicrobial susceptibility testing was performed using the E-test (bioMérieux, France).

    RESULTS: The proportion of obligate anaerobes isolated from the clinical specimens was 0.83%. The Gram-positive anaerobes were most susceptible to vancomycin and imipenem, showing 100% sensitivity to these antimicrobials, followed by clindamycin (86.3%), penicillin (76.7%), and metronidazole (48.9%). Meanwhile, Gram-negative anaerobes were most susceptible to metronidazole (96%) followed by imipenem (89%), clindamycin (79%), and ampicillin (32%). The present study also showed that 3 out of 12 Bacteroides fragilis isolates were resistant to imipenem.

    CONCLUSION: This study demonstrated the differences in the susceptibility patterns of anaerobes towards commonly used antimicrobials for the treatment of anaerobic infections. In summary, continuous monitoring of antimicrobial resistance trends among anaerobes is needed to ensure the appropriateness of treatment.

    INTRODUCTION: Serum protein electrophoresis (SPE) is a well-established laboratory technique. However, reporting of results varies considerably between laboratories. The variation in reporting can cause confusion to the clinician with a potential of adversely impacting patient care. The purpose of the survey was to find out the variation in reporting and to prepare recommendations to the Malaysian laboratories based on the survey to reduce both the variation in reporting between laboratories and the risk of misinterpretation of reports.

    MATERIALS AND METHODS: To determine the extent of variation in reporting of protein electrophoresis results questionnaires were distributed to the pathologists of various laboratories in Malaysia regarding the method, quantification of paraprotein concentrations and immunoglobulin assays, and information regarding current laboratory electrophoresis practices.

    RESULTS: Variation was found in the following reporting practices: (a) screening protocol; (b) reporting of serum albumin; (c) numerical reporting of protein fractions and paraprotein; (d) co-migration of a paraprotein with a normal serum protein; (e) reporting of multiple paraprotein bands (f) appearance of small abnormal band and oligoclonal bands and (g) communication about of interferences.

    CONCLUSION: The pathologists of the country made recommendations on the reporting of protein electrophoresis. Harmonised reporting will reduce inconsistency, variation in reporting, improve the quality of the report and most importantly improve patient care.

    This study aimed to determine the role of surfactant protein A (SP-A) in the formation of stable microbubble in tracheal aspirates. Our results showed that as the concentration of anti SP-A antibodies added to tracheal aspirate specimens increased, the number of stable microbubble formed in the specimen decreased. The correlation between stable microbubble counts and the SP-A levels in the tracheal aspirates was good, r = 0.85, p < 0.05. This study suggests that SP-A plays an important role in stable microbubble formation. Measurement of small stable microbubbles is thus a useful bedside test for predicting the SP-A activity in the tracheal aspirates and in indirect measurement of lung maturity.

    Suicidal feelings and a sense of hopelessness have been regarded as part of the ageing process more so in the context of being elderly and having physical difficulties. As older adults are the fastest growing population in the world, suicides among this population is also expected to increase. The authors retrospectively reviewed all cases recorded by the National Suicide Registry Malaysia (NSRM) for the year 2009. Suicide in victims 65 years and older totaled 23 in number and accounted for 7.1% of all suicides. All the cases were autopsied. The case records were retrospectively analyzed with respect to age, gender, ethnicity and method of death. Comparisons were also made between males and females, levels of education, presence of stressor and life events antecedent to suicide. The ages of these suicide victims ranged from 65 to 94 years. Men comprised almost 70% of the cases. The average age of the victim was 73 years. Hanging was the most common method of suicide, accounting for 56.5% of the cases. Other methods included jumping from height (13.1%), exposure to unspecified chemicals (13.1% ), jumping/lying before moving object (4.3%), exposure to pesticides (4.3%) and injuring oneself using sharp object (4.3%). Death of a loved one, legal problems, financial problems and physical illness were the stressors identified contributing to the suicide act.

    A healthy 17-year-old Chinese male suddenly collapsed and died during a game of badminton. The autopsy examination revealed a solitary calcified aneurysm of the left common coronary artery with marked stenosis of the orifices of the anterior descending and circumflex branches. Histology of the aneurysm was non-specific with hyalinised scar tissue and foci of calcification. The only illness of significance in the past was an episode of 'pyrexia of unknown origin' at the age of 8 months. A review of the notes of that hospital admission revealed that the illness was most probably Kawasaki disease.

    Heat stroke, which is also known as "sun stroke," is a medical emergency, and fatalities can occur unless it is diagnosed early and treated efficiently. Heat stroke may manifest quite suddenly, giving little time to differentiate it from extreme physical exhaustion in collapsed subjects. It is also known to lead to serious disseminated intravascular coagulation. Sudden death in a young female is presented who collapsed after trekking in a hilly, jungle area in Malaysia on a warm, humid day. She had joined a weight reduction programme a few weeks earlier. She was found collapsed and in a semiconscious state in the jungle by her groupmates and was taken to hospital. On admission she was unconscious, hyperpyrexic, with rapid, thready pulse and a low blood pressure. Biochemical studies revealed metabolic acidosis, elevated liver and cardiac enzymes and impairment of renal function. Her coagulation profile was found to be impaired and she started bleeding through the mouth and nostrils. She also developed watery diarrhoea and initially a septicaemic condition, including acute enteritis was suspected. Despite active treatment, her condition deteriorated and she died eight hours after admission. Autopsy confirmed a generalised bleeding tendency, with pulmonary, oesophageal and gastrointestinal mucosal haemorrhages. Flame-shaped subendocardial shock haemorrhages were seen in the interventricular septum on the left side of the heart. The findings support a diagnosis of heat stroke. Various aspects related to heat stroke, the autopsy diagnosis and its prevention are discussed.

    Spontaneous coronary artery dissection is a rare event and commonly associated with pregnancy and female gender. This condition can reduce or completely obstruct the blood flow to the heart, causing a myocardial ischaemia, abnormalities in heart rhythm or sudden death. We present a case of a 28-year-old Indian male with no previous medical illness who complained sudden onset of chest pain prior to his death. Autopsy revealed a left anterior descending coronary artery dissection associated with plaque rupture. The anterior wall of left ventricle showed contraction band necrosis. There was also atheroma present in the right coronary artery which was insignificant. Histologically, dissection was associated with atherosclerosis. There was no evidence of vasculitis. The cause of death was given as coronary artery dissection due to coronary artery atherosclerosis.

    Hirschsprung's Disease (HD) is a congenital disorder causing severe constipation in infants and children. Suction rectal biopsy (SRB) is the preferred technique for obtaining tissue samples for histopathological evaluation. In low-resource settings like Malaysia, cost-effective diagnostic approaches are necessary, making single sample SRB valuable. This study evaluates the diagnostic accuracy and sufficiency of a single macroscopically adequate sample in suction rectal biopsies for the histopathological confirmation of HD. We conducted a retrospective study of children who underwent suction rectal biopsies for the diagnosis of HD at Hospital Raja Perempuan Zainab II (HRPZII), Kota Bharu, Kelantan. A total of 68 patients were included in the study. The inadequacy rate for bedside SRB was 14%, comparable to current literature. Our study found no statistically significant association between sample inadequacy and gestational age, gender, birth weight, or weight at biopsy. Complication rates were 0%, consistent with literature reports. Calretinin staining, an additional technique, was performed in 23 biopsy episodes, with a 4.3% inadequacy rate, compared to 20% in specimens not subjected to calretinin staining. The cost of SRB almost doubled with each additional sample taken, significant in low-resource environments. In conclusion, single sample SRBs can be adequately diagnostic and cost-effective in low-resource settings, providing valuable insights for healthcare facilities in Malaysia and other developing countries. The use of adjunctive techniques such as calretinin staining may improve diagnostic accuracy while maintaining cost-effectiveness. Further prospective studies with larger sample sizes are needed to validate these findings.

    INTRODUCTION: 'InTec Blood Grouping Test kit' using solid-phase technology is a new method which may be used at outdoor blood donation site or at bed side as an alternative to the conventional tile method in view of its stability at room temperature and fulfilled the criteria as point of care test. This study aimed to compare the efficiency of this solid phase method (InTec Blood Grouping Test Kit) with the conventional tile method in determining the ABO and RhD blood group of healthy donors.

    METHODS: A total of 760 voluntary donors who attended the Blood Bank, Penang Hospital or offsite blood donation campaigns from April to May 2014 were recruited. The ABO and RhD blood groups were determined by the conventional tile method and the solid phase method, in which the tube method was used as the gold standard.

    RESULTS: For ABO blood grouping, the tile method has shown 100% concordance results with the gold standard tube method, whereas the solid-phase method only showed concordance result for 754/760 samples (99.2%). Therefore, for ABO grouping, tile method has 100% sensitivity and specificity while the solid phase method has slightly lower sensitivity of 97.7% but both with good specificity of 100%. For RhD grouping, both the tile and solid phase methods have grouped one RhD positive specimen as negative each, thus giving the sensitivity and specificity of 99.9% and 100% for both methods respectively.

    CONCLUSION: The 'InTec Blood Grouping Test Kit' is suitable for offsite usage because of its simplicity and user friendliness. However, further improvement in adding the internal quality control may increase the test sensitivity and validity of the test results.

    INTRODUCTION: Breast cancer is still a serious health problem in 21st century and diagnosis, treatment and prognosis of this malignant disease are subject to many research. While cancer research has been focused on tumour cells primarily, recent studies showed that tumour stroma contribute to carcinogenesis as well as tumour cells. Especially fibroblasts adjacent to epithelial tumour cells are not ordinary fibroblasts and play the critical role. Studies showed that these cancer associated fibroblasts (CAFs) have different genetic profile and protein expression. One of the differently expressed molecules recently found is podoplanin. Podoplanin, utilised as a lymphatic endothelial marker, is found to be expressed in CAFs. The aim of this study is to evaluate the relationship between the stromal expression of podoplanin in invasive breast carcinoma and clinicopathological parameters.

    MATERIALS & METHODS: Podoplanin expression was evaluated immunohistochemically in 153 breast cancers. Tumours with ≥ 10% distinct cytoplasmic podoplanin staining in CAFs were considered as positive.

    RESULTS: In 65.3% of analysed tumours, podoplanin expression was found positive in CAFs. According to our results, podoplanin positive CAFs correlated significantly with tumour size (p= 0.012), tumour grade (p= 0.032) and cerbB2 score (p= 0.032).

    DISCUSSION: Our results suggest that podoplanin expression by CAFs could predict poor patient outcome in breast carcinoma.

    INTRODUCTION: Tumour microenvironment (TME) has been postulated to be involved in cancer development and disease progression. Studies have shown CD10 expressed in cancer-associated fibroblasts (CAF) within TME is associated with aggressive biological behaviour and poor prognosis. The aim of this study was to evaluate stromal CD10 expression in invasive breast cancer and its correlation with tumour stage, grade, Estrogen receptor (ER), Progesterone receptor (PR) and HER2 status.

    MATERIALS AND METHODS: A total of 226 invasive breast carcinoma cases were selected and assembled into tissue microarrays (TMAs). The stromal expression of CD10 was immunohistochemically analysed.

    RESULTS: Stromal CD10 was positive in 67 (29.6%) cases of invasive breast carcinoma. The frequency of positive stromal staining was significantly higher in the cases with ER-negative (P=0.000). CD10 stromal negativity was significantly higher in luminaltype cases (P=0.001). However, there was no correlation between stromal CD10 expression with tumour grade, stage, PR and HER2 status.

    CONCLUSION: Positive CD10 stromal expression correlates with ER-negative invasive breast carcinomas, while negative CD10 stromal expression correlates with luminal type invasive breast carcinomas. This demonstrates that stromal CD10 expression within the TME constitutes a potential prognostic marker and therapeutic target. Future studies are necessary to evaluate other stromal markers within the TME immunohistochemically as well as its molecular basis in order to confirm the definite role of stromal CD10.

    INTRODUCTION: Stature estimation is population dependent, and population-specific regression equations should be generated for accurate anthropological assessments. Nevertheless, stature estimation data was inaccessible and limited in some of the South-East Asian countries. The systematic review was conducted to analyse the regression equations of stature estimations developed in South-East Asian region.

    MATERIALS AND METHODS: A systematic literature search was performed through SCOPUS database and Google Scholar from January till March 2018. All published articles which developed stature estimation from different types of bone, methods and type of statures (i.e. living stature, forensic stature and cadaveric stature) were included in this study. Risks of biases were also assessed. Population studies with no regression equations were excluded from the study.

    RESULTS: Seven studies that met the inclusion criteria were identified. In the South-East Asia region, regression equations for stature estimation were developed in Thailand and Malaysia. In these studies, bone measurements were done either by radiography, direct bone measurement, or palpation on body surface for anatomical bony prominence. All of these studies used various parts of bones for stature estimation.

    CONCLUSION: The most widely used regression equations for stature estimation in South-East Asian population were from the Thailand population. Further research is recommended to develop regression equations for other South-East Asian countries.

    BACKGROUND: Staphylococcus aureus is a leading cause of community as well as healthcare-associated bacteraemia. This study aimed to describe clinical characteristics of S. aureus bacteraemia (SAB) and to evaluate the performance of the Prolex Staph Xtra Latex agglutination test in the identification of Staphylococcus aureus.

    METHODS: Cross-sectional study was conducted from Jun 2018 to May 2019. Isolates from first-positive peripheral blood cultures were tested with Prolex Staph Xtra Latex agglutination test, together with routine tube coagulase and DNase test. All isolates were further confirmed with Vitek2 GP.

    RESULTS: Hundred isolates were tested with Prolex Staph Xtra Latex. Twelve isolates were excluded due to incomplete medical records. Eighty-eight isolates were analysed, yielded sensitivities, specificities, positive and negative predictive values of 100%, 91.7%, 98.7%, and 100%, respectively. Of these, 76 were identified as S. aureus and 12 CoNS. Seventy-six patients were included in the SAB analysis. Fifty-nine out of 76 (78.6%) had underlying comorbidities. Thirty-four percent of the episodes were considered as primary SAB. Skin and soft tissue infection were accounted for the highest source of bacteraemia, 24(31.6%). Both MRSA and MSSA bacteraemia were seen mostly among healthcare-associated bacteraemia (HCA) (7/16, 43.8% and 28/60, 46.7%). Liver cirrhosis was significantly associated with MRSA bacteraemia (P=0.048). Metastatic infection & complicated SAB were identified in 13(17.1%) and 30(39.5%) of cases, respectively. All-cause mortality was 22.4%.

    CONCLUSION: S. aureus bacteraemia is a serious infection associated with significant metastatic complications and mortality. Prolex Staph Xtra Latex agglutination test has excellent sensitivity and specificity with 100% and 91.7% respectively.

    Squamous cell carcinoma-related antigen (SCC-Ag), first described by Kato and Torigoe in 1977, has been cited by various workers as a serological marker for some epithelial neoplasms. The most well-studied is its association with carcinoma of the uterine cervix. In January 1989, we embarked on a prospective, multivariate study at the University Hospital, Kuala Lumpur to assess the usefulness of serologically assaying SCC-Ag (using the Abbott RIA diagnostic kit) in our patients with carcinoma of the uterine cervix. We were also interested to ascertain whether SCC-Ag is a 'general' marker for all histological types of cervical carcinoma or specific for squamous carcinoma. From the time of commencement to June 1990, 35 newly-diagnosed and histologically-proven cases were entered into the study. Of these, 4 were keratinising squamous carcinoma, 18 large cell non-keratinising carcinoma, 3 adenosquamous carcinoma, 7 adenocarcinoma and 3 carcinoma-in-situ. Our preliminary results show that all keratinising squamous carcinoma and 1/3 each of large cell non-keratinising carcinoma, adenosquamous carcinoma and carcinoma-in-situ had positive pre-therapy serum SCC-Ag levels (i.e greater than 2 ng/ml, 2 ng/ml being an arbitrarily selected 'cut-off' value). In contrast, no adenocarcinoma was serologically positive. In addition, keratinising squamous carcinoma had the highest mean pre-therapy serum SCC-Ag level. The results imply that serum SCC-Ag is related to the (1) presence of squamous and not glandular differentiation and (2) degree of squamous differentiation.

    Sporotrichosis is a mycosis caused by a saprophytic dimorphic fungus named Sporothrix schenckii. Infections occur following traumatic inoculation of fungus from plants and infected cat bites and scratches. We report a case of a farmer who presented with a solitary subcutaneous nodule initially diagnosed as a soft tissue tumour. A history of agricultural activity and feline contact should draw the clinician's attention to sporotrichosis, as the diagnosis can be easily missed in atypical cases. The diagnosis, microbiology and management of the case are discussed.
