Faiz M, Rashid F

Malays J Pathol, 2023 Aug;45(2):205-214.
PMID: 37658530

INTRODUCTION: Mutations in FLT3 are the most commonly reported genetic changes in AML patients. These mutations are normally identified in approximately one third of newly diagnosed patients and are reported to have prognostic significance.
MATERIALS AND METHODS: Peripheral blood samples was collected from 63 AML patients to study their morphological, cytogenetic and molecular features. PCR was used to determine the prevalence of FLT3 mutations; internal tandem duplication (ITD) and tyrosine kinase domain (TKD) in AML patients.
RESULTS: Among 63 AML patients, 42 were males and 21 were females with male to female ratio 2:1 with median age of 32 years. AML-M2 was the predominant French-American-British (FAB) subtype (42%) followed by M4 (27%), M3 (8%), M1 (8%), M0 (8%) and M5 (7%) respectively. Cytogenetic analysis of 60 patients showed 58% as cytogenetically normal (CN) whereas 42% had aberrant karyotype.The most frequent aberrations were trisomy8, t(8;21), t(15;17) (8.3%) each, inversion16 (5%), and different deletions (12%) respectively. FAB-M4 subtype showed most of the chromosomal anomalies. Among 63 AML patients, 22% showed FLT3/ITD while 6.4% had D835 mutation after molecular analysis. FLT3 mutations were found in most of the FAB subtypes and cytogenetic groups. FLT3/ITD mutations were more common in patients with normal karyotype (26%) and usually present with hyperleukocytosis but association between two was not significant.
CONCLUSION: The cytogenetic data of adult AML from Pakistan showed presence of favourable prognostic karyotype with comparable prevalence as reported in international data. Moreover, FLT3/ITD mutations are commonly found in our patients as determined by molecular analysis. Therefore, inclusion of this unfavourable prognostic marker should be routine in molecular diagnostic testing of AML.

Vaginal pessaries have long been used in the management of pelvic organ prolapse as an alternative option for surgery. Vaginal cancer is a very rare form of gynaecological malignancy, and its association with vaginal ring pessaries has yet to be clearly established. We examined the cases of vaginal cancers in a tertiary state hospital for the last three years and found four cases of vaginal cancers, in which three of these cases were associated with a long history of using vaginal ring pessary for pelvic organ prolapse. Two of them had defaulted follow- up and presented with a vaginal mass and vaginal bleeding. These two cases did not have evidence of distant metastases, one of them underwent surgical removal of the tumour and radiotherapy, whilst the other case was initially given neoadjuvant chemotherapy, but the patient died prior to her planned surgery. The third patient declined further investigation and treatment after she was diagnosed with vaginal cancer. In conclusion, such potential serious long term complication from vaginal pessary should be informed prior to its insertion, it is also imperative to ensure compliance to regular follow- up for patients on vaginal pessaries, and to biopsy any suspicious chronic vaginal ulcers.

INTRODUCTION: Carpal Tunnel Syndrome is known to be a common complication during pregnancy especially during the third trimester.

AIM: This article focuses on its impact to the third trimester pregnant mothers with CTS.

METHODS: Third trimester pregnant mothers with no other known risk factors for CTS, were interviewed and examined for a clinical diagnosis of CTS. The severity of CTS was assessed by means of symptoms severity and functionality using the Boston Carpal Tunnel Questionnaire.

RESULTS: Out of 333 third trimester pregnant mothers, 82 (24.6%) were clinically diagnosed with CTS. Malay race was found to have significant correlation with the diagnosis of CTS (p = 0.024) and are two times more likely to get CTS during pregnancy (OR = 2.26) compare to the non-Malays. Bilateral CTS was two times higher (n = 58, 63.4%) than unilateral cases (n = 30, 36.6%), however no significant correlation between the two was found with severity (p = 0.284) or functional (p = 0.906). The commonest complaint was numbness/tingling during day time (n = 63, 76.8%). Majority of the CTS cases were mild (n = 66, 80.5%) and approximately one third (n = 28, 34.1%) had affected hand functions. All symptoms related to pain was found to have significant correlation with severity (p = 0.00, OR = 12.23) and function (p = 0.005, OR = 5.01), whereas numbness and tingling does not (Severity, p = 0.843, function, p = 0.632).

CONCLUSION: This study shows that even though CTS in third trimester pregnancy is prevalent, generally it would be mild. However, function can still be affected especially if patients complain of pain.

BACKGROUND: Depression is a recognized complication of lung cancer underreported in developing countries such as Malaysia. Treating and identifying depression in cancer patients increases survival and quality of life. Our objectives are to study prevalence of depressive symptoms in newly diagnosed lung carcinoma, and examine the relationship of depressive symptoms with other influencing risk factors.
METHODS: A 2-year, cross sectional study February 2015-February 2017, was conducted at Hospital Tengku Ampuan Afzan, and Penang General Hospital. One hundred and three patients with newly diagnosed, biopsy confirmed primary lung carcinoma were recruited. Self-rated patient's identification sheet, validated Center for Epidemiologic Studies Depression (CES-D), and Dukes University Religion Index score from three different main languages were used.
RESULTS: Prevalence of current depressive symptoms (CES-D total score ≥16) is 37.9%. The result suggests prevalence of those at high risk of moderate to major depression, may need treatment. Multivariate analysis reveals those with good Eastern Cooperation Oncology Group factor (η2=0.24, p<0.001) married (η=0.14, p<0.001) with intrinsic religiosity (IR) (η=0.07, p<0.02) are more resistant to depression.
CONCLUSION: One in three of lung carcinoma patients, are at increased risk for depression. Clinicians should be aware that risk is highest in those with poor performance status, single, and with poor IR. We suggest routine screening of depression symptoms as it is feasible, to be performed during a regular clinic visit with immediate referral to psychiatrist when indicated.

Trichosporon asahii is a yeast-like fungus that is emerging as an important cause of invasive infections in tertiary medical centres. A 58-year-old Chinese man with no known medical illnesses presented with liver lacerations and multiple fractures following an alleged 12-foot fall at a construction site. The gravity of his injuries and poor haemodynamic status necessitated an intensive care unit (ICU) admission, during which several febrile episodes were detected and multiple antibiotics were administered. After being in the ICU for at least two weeks, a urease-positive yeast was isolated from the patient's blood. The yeast formed dry, fuzzy and wrinkled white colonies on Sabouraud dextrose agar following prolonged incubation, and produced blastoconidia, true hyphae, pseudohyphae and arthroconidia on slide culture. It was identified biochemically by the ID 32 C kit as T. asahii. The yeast had elevated minimal inhibitory concentration (MIC) values to fluconazole, amphotericin B, flucytosine and all echinocandins tested. In view of this, the patient was treated with voriconazole and was successfully transferred to the general medical ward.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides. It is characterized by anorexia, fever, dyspnea, polypnea, cough, and nasal discharges. Gross lesions in the lung such as marbling, sequestra, thickening of interlobular septa, and consolidation are evident. Serological tests including complement fixation test and competitive enzyme-linked immunosorbent assay and molecular tests such as polymerase chain reactions are used for diagnostic purposes. In this study, lung samples of suspected large ruminants (cattle n=560, buffalo n=293) were collected from abattoirs of three districts of Punjab namely Lahore, Kasur and Jhang. PCR was performed with specific primers, targeting the 16S ribosomal RNA gene to detect the positive cases. The results indicated that 49 samples (8.75%) of cattle were positive, with maximum prevalence was observed in Jhang with 16 positive samples (10.06%), but CBPP was not detected in any buffalo sample. High prevalence of disease was seen in cattle of more than seven years of age, in female cattle, and in cross-bred cattle. Age and gender were found significantly associated (P<0.05) with the prevalence of the disease. Gene sequencing of identified 5 isolates of Mycoplasma mycoides subsp. mycoides had more than 99% similarities with the strains isolated from China, Italy, Australia and Tanzania and were categorized into a monophyletic group but strain isolated from Portugal had more than 55% variable regions, hence clustered separately. This study confirms the presence of contagious bovine pleuropneumonia in the country which can be a threat to the livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

INTRODUCTION: Oral health problems are frequently overlooked in patients with epilepsy. We evaluate the oral health status of epilepsy patients from a tertiary teaching hospital.
MATERIALS AND METHODS: We conducted a cross-sectional study of epilepsy patients from the neurology clinic, Hospital Canselor Tuanku Muhriz, Kuala Lumpur. The dental assessment included the decayed, missing and filled teeth (DMFT) criteria, as well as the plaque and periodontal status by dentists.
RESULTS: A total of 151 patients were recruited. The median age of onset of epilepsy was 16 (IQR 7-30) years, with generalised seizures at 59.6% and focal seizures in 40.4% of patients. Fair or poor oral health was present in 59 (39.1%) and gingivitis was seen in 65 (43%). The median DMFT decayed (D), missing (M) and filled teeth (FT) was 3 (IQR 1- 7). The median age of patients with fair or poor oral health was older (40 years, IQR 31-51) than the patients with excellent or good oral health (33 years, IQR 26-45), (p=0.014). Multivariate logistic regression analysis showed that carbamazepine (Odds Ratios, OR: 3.694; 95% Confidence Intervals, 95%CI: 1.314, 10.384) and hypertension (OR 6.484; 95%CI: 1.011, 41.594) are the risk factors for fair or poor oral health. Phenytoin use is 4.271 times more likely to develop gingivitis (OR 4.271; 95% CI: 1.252, 14.573).
CONCLUSION: Factors that contribute to fair or poor oral health include age, antiseizure medications like phenytoin and carbamazepine, and hypertension. Effective preventive strategies should be implemented to maintain oral health in epilepsy patients.
