A review of patients with diphtheria seen in the Paediatric Unit, Alor Star General Hospital, from January 1985-March 1987 is reported. Their clinical presentation, diagnosis, treatment and outcome were analysed and discussed. Clinical awareness regarding the diagnosis of diphtheria is emphasised.
Impairments of lung functionality as long-term effects of cigarette smoking have been well established. To our knowledge, no study on acute recovery patterns in any important lung function index after smoking a very limited number of cigarettes has ever been reported. The present study reports recovery patterns of lung transfer factor (TF) and related parameters in smokers and non-smokers who smoked two Camel cigarettes. Lung transfer factor and other indices were determined by the single breath-holding technique. From our results, the TF and related indices of healthy Malaysians are similar to previously published normals of comparable age. On smoking two cigarettes, male smokers began to recover from the 30th minute; male non-smokers had not begun recovery even by the 50th minute. Extrapolation of the recovery curves suggests that a "safer" interval between cigarettes for male smokers is about 114 minutes.
Circadian variations have been observed in the onset of acute coronary syndromes including acute myocardial infarction. We studied 422 acute myocardial infarction patients who presented to the coronary care unit of General Hospital Kuala Lumpur. Of the 318 (75.4%) patients whose data was complete, a circadian rhythm with bimodal peak was demonstrated. The second quarter of the day i.e. 6.00 a.m. to 12 noon was shown to have a significantly increased frequency of onset of acute myocardial infarction (p less than 0.05). Time delay in presenting to the hospital was also determined. This showed that 56.8% of acute myocardial infarction patients presented early, within four hours of the onset of symptoms. By six hours, more than 71% had sought hospital care. This early presentation to the hospital may offer a realistic opportunity for optimal thrombolytic therapy should this treatment modality be offered as routine to infarct patients.
This report deals with a middle aged man in whom the presenting symptom of the disorder was dysphagia. The clinical approach to the final diagnosis of thyrotoxic myopathy causing dysphagia is outlined and the pathophysiology of dysphagia then discussed. The need to include thyrotoxicosis in the differential diagnosis of an otherwise unexplained case of dysphagia is stressed.
Two hundred and five healthy Malaysian adults were scanned for the length of their kidneys and the cortical thickness by both the sector real time and linear array static B-scan diagnostic ultrasound. The length of the left kidney was found to measure 105 (98-111) mm for males, and 100 (94-106) mm for females on average from the sector scan and the static B-scan. The right renal length was 102 (96-119) mm for males, and 98 (92-103) mm for females on the average from readings of both scans. The left kidney is longer in length than the right kidney in males and females on both scans. The cortical thickness at the equator of the kidneys of males and females ranges from 12-14 mm. In both sexes, the lengths of the kidneys may be estimated by the distance between the first to the fourth lumbar transverse processes when there is no scoliosis.
A study was conducted to determine the prevalence of locomotor disability in a Malay Community in Tanjung Karang, Kuala Selangor in 1984. The causes of these disabilities, the mobility and occupational handicaps they caused and the types of treatment received were determined. Fifty percent of the households in this area were selected by stratified random sampling and all persons above seven years of age were included in the sample. The prevalence of locomotor disability was 3.9%. The prevalence among males was 5.2% and among females 2.6%. The prevalence increased with age, being as low as 0.6% in the 7-14 year age group and as high as 20.5% in the above 55 year age group. The disabilities resulted mainly from trauma (49%) and musculoskeletal and neurological problems (46.9%). Ninety percent (44 cases) had difficulty only in performance of daily activity and 20 cases (40.8%) had no mobility handicap whatsoever. Forty two (85.7%) of the 49 cases had received treatment.
In children, congenital deafness presents not infrequently. The majority of cases are sensorineural in nature and congenital conductive deafness is far less common. The causes range from abnormalties and fixation of ossicles, ankylosed malleo-incudal joint and absence of one or more ossicles. We describe a case of congenital ossicular abnormality, presenting with conductive deafness.
Human infections due to Phialophora richardsiae, first described in 1968, is usually associated with subcutaneous cysts, although there have been reported cases of ulcerative lesions with discharging sinuses as well as infection of bones and tendon sheaths.1,2,3 Because infections by P.richardsiae are rare and the fungus relatively unknown in Malaysia, it was thought worthwhile to report the isolation of this fungus from a cutaneous lesion.
Lactic acid concentration was determined in 37 specimens of cerebrospinal fluid by gas liquid chromatography. It was found to be raised (30 mg/dl) in 15 specimens from culture positive cases of bacterial meningitis and one of fungal meningitis. It was < 30 mg/dl in cerebrospinal fluid from four cases of viral meningoencephalitis and 10 contaminated specimens. It was also raised in two specimens from culture negative cases. Determination of cerebrospinal fluid lactic acid concentration by gas liquid chromatography provides a useful, additional test in the diagnosis of bacterial meningitis
Leiomyoma of the caecum is a rare tumour. While leiomyomata are known to arise from any part of the large bowel, caecum is a rare site. The largest series to date is that of Mackenzie" who reviewed 37 cases of myomatous tumours of the colon, two of which were complicated by perforation. More recently, Swerdlow" reported another case of a perforated caecal leiomyoma. We now report a patient who was operated at the stage of abscess formation without perforation.
