    The optical and textural properties of chicken patty formulated with different level of grey oyster mushroom (Pleurotus sajor-caju) at 0, 25 or 50% to replace chicken meat were investigated. The addition of up to 50% oyster mushroom to chicken patty formulations did not change colour a*(redness),compared with the control patty. Chicken patties containing oyster mushroom had lower L* value ranging from 51.02 – 52.65 compared to that of the control patty (57.86). All oyster mushroom-based patties had lower colour b*(yellowness) value compared to chicken patty without mushroom. The hardness of chicken patty decreased proportionally with the level of oyster mushroom. On the other hand, oyster mushroom-based patties were springier than the control patty. Chicken which was replaced with 25% of fresh mushroom, recorded the highest moisture retention (77.19%) and cooking yield (80.71%), respectively. However, replacement of 25% of oyster mushroom with chicken breast in chicken patty formulation was not change the moisture retention, fat retention and cooking yield compared to control patty. Chicken patty added with 50% ground oyster mushroom the highest concentration of total dietary fibre (TDF) at 4.90 g/100 g compared to chicken patty containing 25% of mushroom (3.40 g/100 g) and control (1.90 g/100 g). In summary, the addition of oyster mushroom in chicken patties has decreased the lightness, yellowness, hardness and chewiness while no changes were noted in the redness of the patties.
  2. Opening up the HIV epidemic: a review of HIV seropositive status disclosure among people who inject drugs
    Nasarruddin AM, Saifi RA, Othman S, Kamarulzaman A
    AIDS Care, 2017 May;29(5):533-540.

    HIV status disclosure plays a crucial role in reducing risk behaviors of drug and sexual partners and thereby limiting HIV transmission. As people who inject drugs (PWID) bear a significant HIV burden and disclosure research among PWID is relatively few, we reviewed the literature to highlight what is known about disclosure among HIV-positive PWID. Searches of articles published from 2000 to 2015 yielded 17 studies addressing different aspects of disclosure, and results are presented by major themes. Our results suggest that despite the difficulties, most PWID (64-86%) disclose their HIV-positive status to trusted individuals (family members and intimate sexual partners) and to those who are known to be HIV-positive. Disclosure to non-intimate sexual partners and fellow drug users is relatively lower. Disclosure decision-making is primarily driven by the perceived positive and negative consequences of disclosure. Subsequent risk reduction practices following disclosure are influenced by the feeling of responsibility, as well as partners' willingness to accept risk. Cultural family values, ethnicity, and different localities were several contextual factors that affect patterns of disclosure and risk behaviors of PWID. Areas for future research are recommended.
  3. Fulltext Bilateral pure gonadoblastoma in a 46 XY individual--a case report
    Siti Aishah MA, Chandran R, Tahir H
    Med J Malaysia, 1991 Dec;46(4):384-7.
    PMID: 1840451
    We report here a rare case of bilateral pure gonadoblastoma which accounts for only 0.2% of all ovarian tumours seen at Universiti Kebangsaan Malaysia from 1980 to 1987. This tumour occurred in an 18 year old Chinese "female" who presented with primary amenorrhoea. Examination showed a phenotypic female with poorly developed external gentalia. Exploratory laparotomy revealed a hypoplastic uterus, rudimentary fallopian tubes and streak gonads. Histological examination of the gonads showed a mixed tumour comprising large germ cells and smaller sex cord derivatives arranged in characteristic nests or islands containing hyaline material.
  4. Fulltext Swyer syndrome in a woman with pure 46, XY gonadal dysgenesis and a hypoplastic uterus
    Azidah A, Nik Hazlina N, Aishah M
    Malays Fam Physician, 2013;8(2):58-61.
    PMID: 25606286 MyJurnal
    Swyer syndrome or pure 46, XY gonadal dysgenesis is a condition in which the individuals have female appearance. They classically present as sexually infantile phenotypic females with primary amenorrhoea. People with this disorder have female external genitalia but the uterus and fallopian tubes are underdeveloped. However, they do not have functional gonads (ovaries or testes). Instead, they have streak gonads. We are reporting a case of Swyer syndrome with partially developed breasts, hypoplastic uterus, and absent streak gonads. The patient was treated with hormonal therapy and few years after her presentation, breast and uterine development were noted. In view that the patient is already married, the option of fertility was discussed with her. This case illustrates a rare case of gonadal dysgenesis and demonstrates the importance of counseling on the options of treatment, especially regarding fertility.
  5. A mouse IgM monoclonal antibody recognizes breast and colon cancer
    Bakar AF, Alitheen NB, Keong YS, Hamid M, Ali SA, Ali AM
    Hybridoma (Larchmt), 2009 Jun;28(3):199-203.
    PMID: 19519247 DOI: 10.1089/hyb.2007.0531
    Hybridoma clone C3A8, which is a fusion product between splenic lymphocytes of Balb/c mice immunized with MCF7 breast carcinoma cells and SP2/0 myelomas, was produced and characterized. A stable clone that secreted IgM monoclonal antibody (MAb) with kappa light chain was obtained through limiting dilutions. Cell-ELISA screening, flow cytometry analysis, and immunofluorescence staining revealed that the MAb C3A8 had bound specifically and strongly to MCF7 and HT29 but cross reacted weakly or not on HeLa cell line. The MAb C3A8 reacted positively with paraffin-embedded tissues of human breast and colon cancers but there were no positive reactions on normal tissues. Western blot analysis showed the MAb recognized a 55 kDa protein, which was present in the extract of MCF7 and HT29 cell lines. Our results demonstrated that MAb C3A8 could be used for basic and clinical research of breast and colon cancers.
  6. Exploring breast carcinogenesis through integrative genomics and epigenomics analyses
    Minning C, Mokhtar NM, Abdullah N, Muhammad R, Emran NA, Ali SA, et al.
    Int J Oncol, 2014 Nov;45(5):1959-68.
    PMID: 25175708 DOI: 10.3892/ijo.2014.2625
    There have been many DNA methylation studies on breast cancer which showed various methylation patterns involving tumour suppressor genes and oncogenes but only a few of those studies link the methylation data with gene expression. More data are required especially from the Asian region and to analyse how the epigenome data correlate with the transcriptome. DNA methylation profiling was carried out on 76 fresh frozen primary breast tumour tissues and 25 adjacent non-cancerous breast tissues using the Illumina Infinium(®) HumanMethylation27 BeadChip. Validation of methylation results was performed on 7 genes using either MS-MLPA or MS-qPCR. Gene expression profiling was done on 15 breast tumours and 5 adjacent non-cancerous breast tissues using the Affymetrix GeneChip(®) Human Gene 1.0 ST array. The overlapping genes between DNA methylation and gene expression datasets were further mapped to the KEGG database to identify the molecular pathways that linked these genes together. Supervised hierarchical cluster analysis revealed 1,389 hypermethylated CpG sites and 22 hypomethylated CpG sites in cancer compared to the normal samples. Gene expression microarray analysis using a fold-change of at least 1.5 and a false discovery rate (FDR) at p>0.05 identified 404 upregulated and 463 downregulated genes in cancer samples. Integration of both datasets identified 51 genes with hypermethylation with low expression (negative association) and 13 genes with hypermethylation with high expression (positive association). Most of the overlapping genes belong to the focal adhesion and extracellular matrix-receptor interaction that play important roles in breast carcinogenesis. The present study displayed the value of using multiple datasets in the same set of tissues and how the integrative analysis can create a list of well-focused genes as well as to show the correlation between epigenetic changes and gene expression. These gene signatures can help us understand the epigenetic regulation of gene expression and could be potential targets for therapeutic intervention in the future.
  7. Mismanagement of cat bite wound: lessons to learn
    Muthupalaniappen L, Siti Aishah MA, Wong YP, Jamil A
    Clin Ter, 2013 May-Jun;164(3):225-7.
    PMID: 23868624 DOI: 10.7417/CT.2013.1553
    Animal inflicted wounds, left untreated may result in chronic bacterial or fungal infection. Clinical features of these infections may overlap leading to a delay in diagnosis and treatment. We report a case of chronic non-healing cat bite wound treated with several antibiotics without improvement. Later patient developed the classical "sporotrichoid spread" and a presumptive diagnosis of sporotrichosis was made. Laboratory investigation for fungal culture and skin biopsy failed to identify the underlying pathogen. A trial of oral antifungal agent resulted in complete recovery of the lesions implicating fungus as the causative pathogen. Physicians should have a high index of suspicion for fungal infections when managing animal inflicted wounds.

    Aminudin CA, Sharaf I, Hamzaini AH, Salmi A, Aishah MAS
    Med J Malaysia, 2004 Dec;59 Suppl F:49-51.
    PMID: 15941162
    Ossifying fibromyxoid tumor (OFMT) is a rare benign tumor, most of which occurs in adults with localization in the subcutaneous tissue or muscle of the extremities. A five-year-old girl presented with a mass in her right upper thigh. Due to the large size of the mass (10 x 7 cm), our provisional diagnosis was a soft tissue sarcoma. A tru-cut biopsy showed that the lesion was benign. The mass was excised and has not recurred since. To the best of our knowledge, this patient is the youngest case of OFMT reported in the English literature.

    PMID: 8183145
    Radiologically guided localization procedures are indicated pre-operatively when breast lesions are nonpalpable. The results of 42 percutaneous hookwire localizations over a period of 3 years are described. Of the total, 7 (17%) were found to be malignant. Biopsy was indicated by mammographically detected mass in 48%, by microcalcifications in 40% and by microcalcifications with an associated mass in 12%.

    PMID: 15190665
    Choroid plexus carcinoma is a rare intracranial neoplasm, affecting mainly very young children. The commonest site is within the lateral ventricles and the prognosis is very poor. We report a seven month old baby boy who presented with raised intracranial pressure and seizures. Brain CT scan showed large intraventricular mass with calcification and hydrocephalus. Total macroscopic resection of the tumour was performed and diagnosis of choroid plexus carcinoma was made. However, the patient died 11 days after the tumour excision. The histopathology of this rare childhood neoplasm is discussed.

    PMID: 25326360 MyJurnal
    hemangiopericytoma (hPC) is a rare tumor by definition and intracranial hPC makes up to less than one percent of all the intracranial tumors. It is a dural base tumor and its clinical features and radiological findings are similar to meningiomas. however, cerebellopontine angle hemangipericytoma had only been reported twice and would almost always be misdiagnosed. definite diagnosis is important, as the treatment of hPC is different from meningiomas and acoustic neuromas. we report a case of a young female who presented with atypical symptoms of left cerebellopontine angle mass. A literature review of the nature of the disease, radiological findings, immunohistochemical features and treatment options of the tumor are described.

    PMID: 24999566 DOI: 10.7417/CT.2014.1711
    Primary nasal lymphomas are rare. One of the most common cellular subtypes in the Asian population is natural killer (NK)/T-cell lymphoma (NKTL) with a high association of EBV. We report a case of a 42-year-old female, who presented with a worsening sore throat, odynophagia, dysphagia to solid food due to oropharyngeal ulcers and bilateral nasal blockage and recurrent fever for the past two weeks prior to admission. Physical examination revealed ulcers over the soft palate with nasopharyngeal slough. Computerized Tomography (CT) scan of the neck showed nasopharyngeal abscess with bilateral maxillary ethnoidal sinusitis. The diagnostic and management challenge is discussed.

    PMID: 22964694
    Epithelioid sarcoma is a very infrequent soft tissue sarcoma involving predominantly distal extremities of adolescent and young adult. We hereby report a case of epithelioid sarcoma in a 34-year-old young adult who presented with 1-year history of a painful left upper limb associated subsequently with warm left forearm swelling and a Volkman contracture. He was treated as an inflamed soft tissue condition of the left upper limb. A computed tomography study showed presence of multiple hypodense lesions mainly in the flexor compartment of the left arm as well at the subcutaneous tissue, which measured 1 to 1.7 cm in diameter. Histological examination of the left upper limb mass showed nodular proliferation of epithelioid tumour cells and some with rhabdoid features surrounding a central zone of necrosis and was diagnosed as epithelioid sarcoma. Concurrent presence of epithelioid sarcoma and Volkman ischaemic contracture are rarely seen in clinical practice. The present case highlights the importance of the histology which can be confused with other types of sarcoma or chronic granuloma and even missed at times thereby causing diagnostic problems.

    PMID: 22041803
    A 30-year-old, nulliparous woman presented with a history of subfertility. On examination she was found to have uterine fibroid of 28 weeks size of gravid uterus and subsequently laporatomy myomectomy was performed. Multilobulated masses, with diameters ranging from 22 mm to 160 mm were found. Cut sections of the lobulated masses showed whitish whorled cut surface. One of the multilobulated masses had a cystic cavity, measuring 60x50x35 mm(3). Light microscopic findings of the mass with the cystic cavity showed a well-circumscribed cellular tumour composed of cells exhibiting moderate nuclear atypia which were enlarged, nuclei with prominent chromatin clumping and were distributed in areas. Some tumour cells showed large nuclear pseudoinclusions, multinucleated or multilobated tumour giant cells, smudging and few enlarged nucleoli. Mitotic activity was 4 MFs per 10 HPFs. Occasional cells with intracytoplasmic inclusions resembling rhabdoid - like features were seen. There were no atypical mitoses or tumour necroses were noted. Diagnosis of atypical leiomyoma or symplastic leiomyoma was made. Atypical or symplastic leiomyomas are rare in the region of Malaysia and the present case discusses its incidence in younger age, its morphological features along with diagnosis and clinical outcome.

    Primary peritoneal carcinoma (PPC) is a rare tumor that is histologically and immunohistochemically indistinguishable from epithelial ovarian carcinoma. The diagnosis is usually made after excluding gross ovarian involvement or the ovarian involvement is only confined to the surface. A 68-year-old lady presented with right iliac fossa pain and increasing CA125. The CT scan showed bilateral pelvic adnexal masses with peritoneal deposits within the right side of abdomen. She was initially diagnosed as carcinomatosis peritonei from the omental cake removed after exploratory surgery. She was managed as advanced ovarian tumor with peritoneal metastasis and was then administered six cycles of chemotherapy. Surgical intervention included debulking surgery consisting of total abdominal hysterectomy, bilateral salpingooophorectomy and omentectomy and also with right hemicolectomy. The histopathological findings were of primary peritoneal serous carcinoma with only minimal involvement of the serosal surface of the right ovarian capsule. No microscopic invasion into underlying ovarian cortex and stroma was observed. Multiple tumor deposits were also seen over the right paratubal and paraovarian tissue, both parametrium as well as serosal surface of the terminal ileum and periappendicular tissue. Immunohistochemically, the malignant cells were positive to CA125, focally positive to CK7 and negative to CD20 and Calretinin. PPC is one of important differential diagnosis which needs to be considered in cases of advanced ovarian tumor, although the former can only be ascertained after excluding the ovarian involvement microscopically.

  20. Routine vaginal examination to assess labor progress at 8 compared to 4 hours after early amniotomy following Foley balloon ripening in the labor induction of multiparas: a randomized trial
    Aishah M, Kamarudin M, Hong J, Sethi N, Hamdan M, Tan PC
    Am J Obstet Gynecol MFM, 2024 Apr;6(4):101325.
    PMID: 38447677 DOI: 10.1016/j.ajogmf.2024.101325
    BACKGROUND: Vaginal examination to monitor labor progress is recommended at least every 4 hours, but it can cause pain and embarrassment to women. Trial data are limited on the best intensity for vaginal examination. Vaginal examination is not needed for oxytocin dose titration after an amniotomy has been performed and oxytocin infusion started. The Foley balloon commonly ripens the cervix without strong contractions. Amniotomy and oxytocin infusion are usually required to drive labor.

    OBJECTIVE: This study aimed to evaluate the first vaginal examination at 8 vs 4 hours after amniotomy-oxytocin after Foley ripening in multiparous labor induction.

    STUDY DESIGN: A randomized controlled trial was conducted from October 2021 to September 2022 at the University Malaya Medical Center, Kuala Lumpur, Malaysia. Multiparas at term were recruited at admission for labor induction. Participants were randomized to a first routine vaginal examination at 8 or 4 hours after Foley balloon ripening and amniotomy. Titrated oxytocin infusion was routinely commenced after amniotomy to initiate contractions. The 2 primary outcomes were the time from amniotomy to delivery (noninferiority hypothesis) and maternal satisfaction (superiority hypothesis). Data were analyzed using the Student t test, Mann-Whitney U test, and chi-square test (or Fisher exact test), as suitable for the data.

    RESULTS: A total of 204 women were randomized, 102 to each arm. Amniotomy to birth intervals were 4.97±2.47 hours in the 8-hour arm and 5.79±3.17 hours in the 4-hour arm (mean difference, -0.82; 97.5% confidence interval, -1.72 to 0.08; P=.041; Bonferroni correction), which were noninferior within the prespecified 2-hour upper margin, and the maternal satisfaction scores (11-point 0-10 numerical rating scale) with allocated labor care were 9 (interquartile range, 8-9) in the 8-hour arm and 8 (interquartile range, 7-9) in the 4-hour arm (P=.814). In addition, oxytocin infusion to birth interval difference was noninferior within the 97.5% confidence interval (-1.59 to 0.23) margin of 1.3 hours. Of the maternal outcomes, the amniotomy to first vaginal examination intervals were 3.9±1.8 hours in the 8-hour arm and 3.4±1.3 hours in the 4-hour arm (P=.026), and the numbers of vaginal examinations were 2.00 (interquartile range, 2.00-3.00) in the 8-hour arm and 3.00 (interquratile range, 2.00-3.25) in the 4-hour arm (P
