    Malignant neoplasms diagnosed histologically in the state of Sabah during the period November 1983 to October 1988 were analysed to determine the distribution of malignant neoplasms according to site, age, sex and major ethnic groups. The five commonest malignant neoplasms in males were carcinomas of the nasopharynx, stomach, skin, lung and liver. In females the five commonest malignant neoplasms were carcinomas of the cervix uteri, breast, ovary, thyroid and skin. There was variation in these frequencies among the major ethnic groups. The most striking of these was the high frequency of nasopharyngeal carcinoma among Kadazan and Chinese males but not in males of the other indigenous groups. A significant number of patients with nasopharyngeal carcinoma was found in the younger age groups and most of the patients in the younger age groups were Kadazans. A relatively high frequency of carcinoma of the stomach, skin and liver was seen among Kadazans and other indigenous groups while carcinoma of the lung was seen relatively frequently among Chinese males. Among females carcinomas of the breast and cervix uteri were the most frequent malignant neoplasms in all the main ethnic groups. Possible reasons for these findings are discussed.

    One hundred patients with carcinoma of the cervix stages 1B to 4A were treated with intracavitary high dose rate radiation using a linear cobalt source. All cases have received external beam pelvic irradiation to 4500cGy mid plane in twenty fractions over four weeks. The results in terms of patient compliance and convenience were good while acute and late morbidities were comparable to standard Manchester technique of low dose rate intracavitary therapy as practised in the Institute of Radiotherapy and Oncology General Hospital Kuala Lumpur. The four year actuarial survival rate is 76% for stage II and 48% for stage III. All three stage IV patients died within 1 year. Four out of seven stage I patients are alive (minimum follow-up 18 months, longest 43 months). One died of systemic spread at 33 months while one is lost to follow up.

    Retinoblastoma was clinically diagnosed in 38 patients in the University Hospital between 1968 to 1988. White pupil or cat's eye reflex, found in 25 patients, was the most common symptom. Four patients refused any form of treatment. Of the 27 histopathologically confirmed cases, 16 were males and 11 were females. There was no ethnic group predominance, although a male preponderance was observed among Malay patients (M:F 3:1, p less than 0.05). Treatment in cases with unilateral disease, without extra ocular extension consisted of enucleation of the involved eye, with close examination of the contralateral eye in follow-up. In cases presenting with bilateral tumour the worse eye was removed. Of 20 cases of histopathologically proven unilateral retinoblastoma treated surgically, 12 patients survived for a mean period of 4.5 years (Range: 1-19 years). The defaulter rate for this group of patients was 55%. None of the 7 cases of bilateral retinoblastoma survived beyond 5 years (Mean survival 2.5 years).

    Even though artificial heart valve implants have a history of some 30 years, there is to this day no ideal valve substitute. Each of the categories of substitutes used has its own advantages as well as problems. Since my last review on the subject, that appeared in this journal, was some 13 years ago (Lim, 1977), it is perhaps appropriate to provide an update on the status of cardiac valve replacement for the general local readership.

    Twelve cases of primary hyperparathyroidism operated by the Universiti Kebangsaan Malaysia Surgical Team from 1978 to 1989 were reviewed. There was a preponderance of Indian females in this series. The majority of the cases presented late and with complications. Renal calculi and bone disease were the commonest complications noted. Of the 12 patients, 9 had single parathyroid adenoma of which 4 were ectopically located, and 2 had hyperplasia of the parathyroids. These were all successfully operated. The remaining patient had 2 failed neck explorations. Failure at initial exploration was due to ectopic location of the glands. Meticulous surgical technique, knowledge of the anatomical variations of location of the parathyroid glands and availability of frozen section facility are essential for successful outcome.

    Two-hundred and sixty-five patients with asymptomatic proteinuria and/or haematuria were studied at the Department of Medicine, Universiti Kebangsaan Malaysia and Department of Nephrology, General Hospital Kuala Lumpur. They represented 25.4% of all the renal biopsies performed during the period 1980-88. All the three races were affected with 71.3% occurring between the ages of 20-39 years and 41.1% were detected during routine medical examination. Excluding those patients with lupus nephritis, IgA nephropathy was the commonest histological diagnosis (51.7%). The presence of severe and advanced histological changes in a significant number of biopsies emphasises the need for more effective screening and early referral of this group of patients.

    Eight general practitioners participated in a survey of content of general practice. This is useful as an indicator or morbidity in the community as well as of workload of general practice. A total of 3164 consultations were recorded, of which 2764 (87%) were because of an illness and the rest (13%) for other reasons like medical examinations, antenatal check, family planning advice, pregnancy tests, pap smear and vaccination. The old and the young have high consultation rates for an illness, men consulted as often as women. The most common illness seen was upper respiratory tract infections, accounting for 37% of all illnesses. Other common minor illnesses were skin infections (6%), genito-urinary infections (5%), minor musculoskeletal (6%) and gastrointestinal (6%) complaints as well as minor injuries and cuts (4%). Major disorders form an unusually low proportion (18%) of all illnesses seen, in comparison with figures from United Kingdom. The common major disorders seen were hypertension, asthma, chronic rheumatic disorders and diabetes. Circulatory disorders were remarkably rare, accounting for only 1% of illnesses. Psychological disorders, both major and minor, were also rarely seen, accounting for only 1% of illnesses which is in marked contrast with figures from the United Kingdom. Factors contributing to these notable findings are discussed.

    Damage to the lower ureters during pelvic surgery is a serious and well-recognised complication. This iatrogenic injury, when undetected intra-operatively, continues to give rise to significant patient morbidity. In 1987, this Department was referred 18 cases of iatrogenic ureteric injuries. 16 patients were from gynaecologic surgery and 2 patients were from general surgery. Only 4 cases (24%) were detected and referred intra-operatively. 13 patients presented post-operatively with various symptoms viz., anuria, loin pain and urinary leak per vagina. Good recovery of urinary function was achieved in all cases after urological intervention, usually by ureteric re-implantation.

    A study of completed in-patient suicides at the University Hospital Kuala Lumpur (UHKL) and Hospital Bahagia Ulu Kinta (HBUK) between 1st January 1967 to 31st December 1987 were conducted. Records of completed in-patient suicides during the period were exhaustively studied. Only 18 cases were from UHKL and 23 cases were from HBUK. It was found that the suicide patients were mainly young Chinese males from the lower socio economic group. The main reasons for suicide were interpersonal conflicts and physical illness. Alcohol was not an important factor unlike patients in the West.. Suicidal intent was also important. Many of the suicides were committed during the early hours of the morning and they usually occurred at inaccessible places. The method was strongly influenced by availability. To the best knowledge of the author, this is the first study of in-patient suicides in Malaysia.

    A review of malaria cases over a five year period from 1984-1988 at the University Hospital, Kuala Lumpur, Malaysia is presented. A total of 64 cases were recorded; 50% of which were due to Plasmodium falciparum, 40.6% were due to Plasmodium vivax, 6.2% due to Plasmodium malariae and 3.1% due to a mixed infection of Plasmodium falciparum and Plasmodium vivax. The breakdown of species type compared similarly with other studies conducted in the region. Of this total, sixteen cases were imported from Pakistan, India, Thailand, Indonesia, Sri Lanka, Vietnam, Madagascar and Mali. The presenting symptoms and the clinical findings were typical of a malaria infection. The main problem in the future will be the increase in imported cases of malaria.

    A review of the records at a teaching hospital in Kelantan revealed that 175 new cases of peptic ulcer disease were diagnosed endoscopically over a period of 5 years. The ratio of duodenal to gastric ulcers was 2:1. Male patients outnumbered females by 2.7:1. There was a disproportionately high number of Chinese patients. A striking observation was that an unusually large proportion (45%) of patients had presented with acute gastrointestinal bleeding. The implication is that peptic ulcer disease in this region may be underdetected; the diagnosis often coming to light only after a serious complication has supervened.

    The propensity of choriocarcinoma to metastasize to lungs, liver and brain is well known. Though theoretically metastases are possible to anywhere in the body, renal metastases are rare. A 56 year old Malay woman who had total abdominal hysterectomy in 1985 for molar pregnancy presented with haemoptysis and dyspnea in 1990. Examination showed she had choriocarcinoma with pulmonary and renal metastases.

    Two cases of girls seen in Sarawak with the diagnosis of Rett Syndrome are reported. Their ages were 6 and 2 years respectively at the time of the report. Diagnosis is made clinically as there is as yet no scientific marker. Specific diagnostic criteria were met. There was a history of slowing of development followed by loss of previously acquired skills, changes in emotional development and behaviour and the definite emergency of stereotyped behaviour especially hand wringing in both girls. Onset was early in both girls, around nine months. Both girls are profoundly retarded mentally but the regression appeared to be static at present.

    A young male who developed ipsilateral pulmonary oedema on two occasions as a complication of treatment of pneumothoraces involving the left lung is reported. The importance of large pneumothoraces, the rapidity of decompression and the application of suction to the pleural space as factors predisposing to the development of re-expansion pulmonary oedema is well demonstrated by this case. The re-expansion pulmonary oedema was more severe on the second occasion when the lung had collapsed for a longer duration compared to the first pneumothorax which was of more recent onset.

    One of the babies in a pair of xiphaomphalopagus conjoined twins developed oliguria, transient rise in serum creatinine and persistent nephrogram on the sixth day of life following injection of radiocontrast medium for computerised axial tomography scanning of the urinary system. The other twin was spared but developed hypertension and "dialysed" the oliguric twin. The renal profiles of both neonates subsequently remained normal until they reached adequate weight for surgical separation at a later date.

    Low birth weight babies are defined as those weighing under 2,500 g. They make 13.5% of all births at the Maternity Hospital, Kuala Lumpur but contribute to 74.8% of all deaths. They are most likely to be Indian babies and least likely to be Chinese. Among all 3 communities, the primigravidae tend to produce smaller babies than multiparae but this is also true for the Indian of parity more than 3. The Malay teenager is more likely to produce small babies than their older counterparts but not so with the Indian and Chinese. There are definite clinical factors associated with or causing the births of small babies and the lighter the baby, the more influential are these factors. Maternal hypertension, antepartum haemorrhage, multiple pregnancy and unexplained intrauterine death are the 4 outstanding associations with both low birth weight and perinatal death. Although the spontaneous (often premature) onset of labour was the commonest preceding factor, it was much less important in the lowest birth weight groups of babies and was a less important contributor to perinatal death.

    Immunoperoxidase staining was compared with flowcytometry for the enumeration of lymphocyte subsets. The percentages obtained for peripheral blood lymphocytes using immunoperoxidase (CD3 = 76 CD4 = 27.9, B = 10.7 CD4/CD8 = 1.8) differed significantly from those obtained by flowcytometry (CD3 = 65.7 CD4 = 39.4, CD8 = 25.6, B = 16.7, HLA DR = 11.9 CD4/CD8 = 1.54) for certain subsets (CD3, CD4, B). There was no significant difference in lymphocyte subsets between children and adults using the same method. These differences are probably due to the different methods used to prepare lymphocytes for analysis. Other factors that should also be considered are the presence of CD4 antigen on monocytes and CD8 on natural killer cells.

    We collected data on patients above the age of 5 years with acute bronchial asthma who presented to the emergency room of Hospital Sains Universiti Sains Malaysia during the period between 1 January to 31 March 1990. Two hundred and twelve patients (57% males and 43% females) who made a total of 271 visits were recorded. This constitutes 16.3% of all adults and paediatric medical cases seen in the emergency room during this period. The majority of patients presented between 8 pm and 6 am which contrasts with the attendance pattern due to other causes. We also recorded two peak periods of presentation (between 8 pm and 12 midnight and between 6 am and 10 am). Thirty-one (11.4%) cases resulted in admission. Of the 240 cases that were successfully treated and discharged from the emergency room, there were 59 relapses (in 45 patients). Twenty-two percent of the relapses occurred within 24 hours of the last visits. We recorded lower rates of admission as well as relapses compared to all previous studies. Our finding of bimodal pattern of presentations was also not previously reported.

    Vaginal vault prolapse after hysterectomy is a distressing complication for both the patient and the surgeon. Successful repair of post-hysterectomy vault prolapse is one of the most difficult problems in gynaecological surgery. The aim of the surgery should be to restore coital function and cure the prolapse permanently.
