Fulltext Aberrancies of human T--and B--lymphocyte populations in peripheral blood

Gan SC, Yeoh CW

Med J Malaysia, 1980 Jun;34(4):379-82.
PMID: 6971393

Strict precautions were taken in our methodology to exclude any monocytes from being included in the total T and B cell estimation. There is a progressive drop in the percentage of T and B cells with age, but no significant differences between the races nor between the sexes of the same age group. Aberrancies of T and B cell percentages were noted in most infections, malignancies and even malnutrition.
Fulltext A case report of near-missed heat stroke

Yeoh CW, Law WC

Medicine (Baltimore), 2023 Dec 22;102(51):e36676.
PMID: 38134114 DOI: 10.1097/MD.0000000000036676

RATIONALE: Heat-related illnesses have protean manifestations that can mimic other life-threatening conditions. The diagnosis of heat stroke requires a high index of suspicion if the patient has been exposed to a high-temperature environment. Central nervous system dysfunction is a cardinal feature. Strict adherence to temperature criteria can potentially lead to misdiagnosis.
PATIENT CONCERNS: A 37-year-old construction worker was brought in by his wife and coworker due to a sudden loss of consciousness while resting after completing his work.
DIAGNOSES: Due to challenges faced during the coronavirus disease 2019 pandemic, as well as language barriers, a detailed history from the coworker who witnessed the patient's altered sensorium was not available. He was initially suspected of having encephalitis and brainstem stroke. However, subsequent investigations revealed multiorgan dysfunction with a normal brain computed tomography and cerebral computed tomography angiogram. In view of the multiple risk factors for heat stroke, pupillary constriction, and urine color suggestive of rhabdomyolysis, a diagnosis of heat stroke was made.
INTERVENTIONS: Despite delayed diagnosis, the patient's multiorgan dysfunction recovered within days with basic supportive care.
OUTCOMES: There were no noticeable complications on follow-up 14 months later.
LESSONS: Heat stroke can be easily confused with other neurological pathologies, particularly if no history can be obtained from the patient or informant. When approaching a comatose patient, we propose that serum creatinine kinase should be considered as an initial biochemical screening test.
Fulltext Acromion Morphology of Patients with Rotator Cuff Disease in Standard AP Shoulder Radiograph in Hospital Sultanah Bahiyah and Hospital Kuala Lumpur

INTRODUCTION: Rotator cuff pathology is commonly attributed to acromion morphology that is demonstrable in standard AP shoulder radiographs by measuring the critical shoulder angle (CSA), the lateral acromial angle (LAA), and the acromial index (AI). However, these parameters vary among races and countries. Therefore, our study aimed to get the local data on acromion morphology in patients with rotator cuff disease.
MATERIALS AND METHODS: MRI shoulder reports between January 2012 and June 2018 were reviewed. The study group consisted of 47 patients with rotator cuff injury with a partial or complete tear, and a control group of 37 patients with tendinitis or osteoarthritis and intact rotator cuffs. The CSA, LAA, and AI of both groups were measured on the anteroposterior shoulder radiograph. The risk factors for both groups and the acromion morphology were recorded.
RESULTS: The CSA for the rotator cuff tear and the control group was 39.08° and 38.28°, LAA was 72.57 ° and 73.51°, and AI was 0.79 and 0.75. The acromion morphology differed in terms of gender, and only LAA was different among the different ethnic groups. There was a negative correlation between age and CSA, age and AI, LAA and CSA, LAA and AI, but a positive correlation between AI and CSA.
CONCLUSION: The CSA for rotator cuff tear patients in our population was 39.08°, LAA was 72.57°, and AI was 0.79. The acromion morphology was significantly influenced by age and gender.

A report of a patient with Lazarus phenomenon (the return of spontaneous circulation after cardiopulmonary resuscitation) following cardiac arrest (myocardium ischemia) is presented. A 65 year patient was found unconscious at home. He taken to the emergency department On arrival he was unconscious, his pupils fixed and dilated bilaterally. Resuscitation proceeded for 55 minutes. He was then pronounced dead. Forty minutes later spontaneous breathing was noted and his blood pressure was 110/48 and heart rate 90bpm. He survived a further 13 days in the coronary care unit. The implications for management of cardiac arrest in the emergency and medical department are discussed.
