The pregnancy outcome of 33 women with gestational diabetes who were treated with glibenclamide and changed to insulin if glibenclamide failed, were compared with the pregnancy outcome of 21 women with gestational diabetes treated conventionally with insulin. The pregnancy outcome, with regard to the overall glycaemic control, rates of preterm labour, neonatal hypoglycaemia, fetal macrosomia, perinatal morbidity and mortality, were not statistically different between the two treatment groups. The limited number of women studied, and the non-random allocation of these women to each treatment group however, could have influenced these results. There were a few observed differences in the pregnancy outcome between the two treatment groups, which although were not statistically significant, caused some concern. In particular we noted an increased rate of fetal macrosomia in the glibenclamide treated group, which in theory could have been drug mediated.
Kaposi's sarcoma is an uncommon cutaneous neoplasm seen classically in elderly males of East European or Jewish extract. It has been known to be endemic in sub-Saharan Africa for many years. Numerous cases had been described in patients on long-term immunosuppressive therapy and in patients living with acquired immunodeficiency syndrome (AIDS). In spite of the increasing number of organ transplant recipients and people living with AIDS. Kaposi's sarcoma remains rare in Asia. We report two cases seen in Johor, Malaysia.
The anaesthetic experience in three patients undergoing thoracoscopic oesophagectomy is discussed. The indications for surgery and the premorbid states are outlined. The necessity for one-lung ventilation, with its attendant cardiopulmonary effects, the difficulty of patient access and the assessment of blood loss were the main problems encountered. Pulmonary morbidity was high in the post-operative period despite the avoidance of thoracotomy. Two patients developed persistent vocal cord paralysis. In conclusion, the role of thoracoscopic oesophagectomy needs further evaluation.
Interstitial lung disease (ILD) is very rare in children. In the majority of cases the aetiology is unknown. Very little is known about the clinical course of this condition in children. Prognosis may be influenced by sex, age of onset of symptoms, radiographic features, presence of right ventricular hypertrophy and histopathology. We report our experience in managing four children with interstitial lung disease. All these children presented in early infancy with cough, respiratory distress, cyanosis and failure to thrive. Three of these children had finger clubbing and right ventricular hypertrophy. All patients received oral steroids. Chloroquine was added in two patients who showed no response. A trial of oral cyclophosphamide was started in one patient who failed with both drugs. One child is oxygen independent while another is on home oxygen therapy. The other two patients eventually died.
Ureaplasma urealyticum was isolated from the endotracheal aspirates of 39 (21.4%) of 182 neonates with respiratory distress requiring ventilatory support. Mycoplasma hominis was isolated from one (0.5%) neonate. Bacterial cultures were negative in 123 (67.6%) neonates. Antibiotic susceptibility test carried out on ten isolates of U. urealyticum showed that all the organisms were sensitive to erythromycin but resistant to lincomycin and sulfamethoxazole trimethoprim. All, except one, U. urealyticum were sensitive to tetracycline and minocycline. Two isolates were resistant to ciprofloxacin. This study showed that U.urealyticum was a common organism isolated from the endotracheal aspirates of neonates with respiratory distress.
A case control study was conducted in 1996 among primary school student in Terengganu. The objective of the study is to determine the relationship between road traffic accidents and factors such as socio-economic status, distance from school, number of siblings, behavioural problems, knowledge and attitudes of pupil and their parents towards road safety and parents' educational status. A total of 140 cases was obtained from 3 urban schools and 3 from rural schools. Cases were matched with control according to age sex and locality of residence. There were significant associations between road traffic accidents and pupils' knowledge regarding road crossing (OR = 0.40, 95% CI = 0.19-0.85), parental supervision (OR = 0.43, 95% CI = 0.19, 0.64) and parents having driving licences (OR = 0.99, 95% CI = 0.856-0.999). Road safety education for pupils and parental supervision are key measures in preventing road traffic accidents among primary school children.
There is now increased public awareness of the value and role of cardiopulmonary resuscitation (CPR). It is therefore not surprising that the public expects a reasonable level of expertise of medical doctors in the application of the CPR techniques during emergency situations. Newly qualified doctors often lack confidence and are usually at a loss when faced with such situations as they have never had practical training before graduation. Most doctors are gradually introduced to CPR as part and parcel of their clinical experience. Many begin to attend formal CPR workshops later in their careers. Medical schools are expected to produce well trained doctors who are competent in clinical practice which include the techniques of basic resuscitation. By virtue of their expertise in airway management and clinical resuscitation, anaesthesiologists can significantly contribute to the teaching of CPR in the undergraduate medical curriculum. This is a retrospective review of Basic Life Support programmes conducted at the Department of Anaesthesiology, Faculty of Medicine, Universiti Kebangsaan Malaysia.
K1 strain of Plasmdoium falciparum is resistant in vitro to chloroquine, pyrimethamine and sulfadoxine. Response of this strain to combinations of antimalarial drugs in the in vitro hypoxanthine incorporation test was coupled with that of a line of strain NF54 relatively sensitive to chloroquine and fully sensitive to other antimalarials. Pyrimethamine and sulfadoxine showed potentiative synergism against NF54 and less marked against K1. Erythromycin and chloroquine showed potentiation, but less marked against NF54. Quinine and clindamycin had an additive effect against NF54 but potentiated against K1. Combinations of chloroquine with quinine or amodiaquine or of amodiaquine with clindamycin or erythromycin showed mild antagonistic or additive effects. In vivo studies in mice, using the 4-day suppressive test, the AS(3CQ) clone of Plasmodium chabaudi was resistant to pyrimethamine and chloroquine but sensitive to sulfadoxine. Similar combinations as above were carried out and their responses were compared between the resistant and sensitive strains. For both strains, the combinations of chloroquine-erythromycin, pyrimethamine-sulfadoxine, quinine-clindamycin showed potentiation; antagonistic effects were observed in chloroquine-amodiaquine combinations whereas when amodiaquine combined with erythromycin the effect was additive. Amodiaquine-clindamycin and chloroquine-quinine combinations have an antagonistic effect against the sensitive strain but additive against the resistant strain.
MRI is now an important diagnostic tool in medical management. There are numerous safety issues to be considered by the clinicians prior to requesting an MRI examination for their patients. These include those related to the magnetic field, gradient magnetic fields, the patient and contrast medium. This paper discusses the dangers and necessary precautions essential to reduce the risk of untoward complications from MRI.
A case of unsuspected penetrating cardiac injury is presented. It was recognised by the presence of bleeding into peritoneal cavity even after the source of bleeding from intra-abdominal organs had been stopped. It highlights the importance of high index of suspicion of associated cardiac injury in high epigastric penetrating injury.
The obstetric flying squad has been used in obstetric practice since 1933 to manage obstetric emergencies occurring in domicilliary practice. It has often been criticised in such situations as only delaying effective treatment to the patient. We have introduced the obstetric flying squad in an urban setting to cater for obstetric emergencies occurring in private practice. This service has been used on ten occasions since its inception without any maternal deaths being recorded or any delay in the provision of emergency care. The flying squad has led to closer cooperation between the government and private sectors in providing obstetric care.
Acute promyelocytic leukemia (APL) in pregnancy poses serious danger to both the mother and fetus. Cytotoxic chemotherapy may cause teratogenicity to the fetus. APL is unique because it is usually associated with a coagulopathy that markedly increases the risk for the mother and fetus. A 21 year old lady with APL in her third trimester of pregnancy was treated with oral tretinoin. Tretinoin reversed the coagulopathy and normalised her blood counts without causing cytotoxic damage associated with cancer chemotherapy. Fetal distress occurred at 37 weeks of gestation and an emergency caesarean section was performed without complications and no blood transfusion support was needed as her coagulopathy and thrombocytopenia had resolved. A remission was achieved with only tretinoin induction. She subsequently had consolidation and maintenance chemotherapy. The mother and baby remain well at 4 years from completion of chemotherapy. A total of 10 pregnancies associated with APL have been reported in the current literature. Premature delivery and a fetal arrhythmia were the only complications. Although retinoin is considered teratogenic, its use so far in second and third trimester has been safe.
A case report of adenoid cystic carcinoma of the trachea is presented. A high index of suspicion is required to make the diagnosis of tracheal tumours early since the patients tend to have normal chest radiographs which on closer examination may show an abnormality of the tracheal column. Adenoid cystic carcinoma is the most common malignant tumour of the trachea. Locoregional control of this disease is achieved by a combined modality therapy of surgery and postoperative radiotherapy. Despite this, it still has a prolonged clinical course and the tendency for delayed onset of distant metastases.
Routine ordering of pre-operative investigations yields a low true positive rate and is not cost effective. In this study, case notes of 251 adults who underwent elective surgery were reviewed. Pre-operative investigations were classified as 'indicated' or 'not indicated', based on the national guidelines. Only 56% of all tests done were indicated. The overall rates of expected and unexpected abnormal values from pre-operative blood investigations were 51.1% and 34.4% respectively. This study found that selective testing based on guidelines was beneficial. However, the results also suggest that the local guidelines need to be reviewed.
