Isolated involvement of the clitoris by vascular malformation (VM) is very rare. Clinically, the lesion simulates female pseudohermaphroditism. A five-year-old girl presented with clitoromegaly and a clinical diagnosis of solitary VM of the clitoris was made. Magnetic resonance imaging showed characteristic features and confirmed the diagnosis and the extent of the VM. This is the first reported case of isolated involvement of the clitoris by VM to be diagnosed preoperatively.
Pheochromocytoma is a rare catecholamine-secreting tumour typically arising within the adrenal medulla. It may occur sporadically or be associated as part of a tumour syndrome including Von Hippel Lindau (VHL), Multiple Endocrine Neoplasia (MEN) 2 and Neurofibromatosis Type 1. VHL is associated with multi-organ involvement of benign and malignant tumours characterized by the presence of retinal angiomas, hemangioblastomas of the cerebellum and spinal cord, renal cell carcinomas, pheochromocytomas and other cystic lesions in the kidneys, pancreas, and epididymis. It is a rare disorder with prevalence estimated at 2-3 per 100,000. This case report describes a 37 years old Chinese gentleman who presented to our institution for further management of bilateral pheochromocytoma and retinal angioblastoma with problems of duodenal ulcer and anaemia. There was no family history of similar problems. With these features the criteria for the diagnosis of von Hippel Lindau disease was established.
We report a case of a child with severe congenital neutropenia (Kostmann's syndrome) who was treated with daily prophylactic subcutaneous granulocyte colony-stimulating factor (G-CSF) from the age of eight to sixteen years before being discontinued for poor haematological and clinical response. She did not have a HLA-matched sibling to enable bone marrow transplantation. She subsequently developed acute megakaryoblastic leukemia at the age of 17 years and succumbed during induction chemotherapy. The role of G-CSF in the pathogenesis of her malignant transformation to AML is complicated as this disorder has a propensity for myelodysplasia or AML as part of its natural history.
Various complications are associated with the use of indwelling voice prostheses. We present problems faced by a patient with his Voice-Master prosthesis, the ingestion of the prosthesis followed by a potentially fatal aspiration. The Voice-Master is unique in that in can be re-inserted. The safety strap is removed after primary insertion once the prosthesis is secure. However, during re-insertions this safety mechanism is no longer present. Therefore we recommend the placement of a temporary stitch or tie to minimize the risks of ingestion or aspiration of the prosthesis during re-insertions.
Third ventricular cavernous angiomas are rare vascular malformations of the brain. We report an eight-year old boy with a rare third ventricular cavernous angioma that hemorrhaged presenting with symptoms of acute hydrocephalus. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a heterogenous ill-defined, solid and cystic intraventricular mass in the third ventricle which was mildly enhanced with contrast and there was associated hydrocephalus. The mass was removed with success and follow up after two years revealed no neurological abnormalities.
Cholesterol granuloma in the paranasal sinuses is rare. It is more common in the mastoid antrum and temporal bone air cells in chronic middle ear disease. A case of bilateral maxillary sinus cholesterol granuloma that mimics chronic maxillary sinusitis is reported. This is the first reported case of cholesterol granuloma of the maxillary sinus in the Malaysian Literature.
Sir, I read with interest the elegantly written CME article by Liam C K recently!. The choice of empiric antibiotic(s) in treating hospitalized adult patients with communityacquired pneumonia (CAP) is important as it can influence clinical outcomes 2. As correctly pointed out by the author, patients with CAP requiring hospitalization should, in addition to a ~-lactam stable antibiotic, be covered with a macrolide, to combat atypical pathogens such as Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydia pneumoniae. Such is the recommendation from most foreign guidelines 3. 4. Here I wish to add our own observation based on a prospective study conducted between 2002 and 2004 of 141 adult patients with CAP hospitalized in Seremban Hospital in which we studied the clinical outcomes of patients treated empirically with and without a macrolide added to their ~-lactam stable antibiotic, recently published in Respirology 5.
Complementary Medicine (CM) usage amongst asthmatic patients was studied. Eighty-eight patients, selected by systematic random sampling in two public polyclinics in April/May 2004, were interviewed. They completed a structured pre-tested questionnaire. Forty-one percent were using CM, majority (64%) together with conventional therapy. Eighty-one percent did not inform their physicians of their CM usage. More Malays were using CM which included nutritional supplements, herbs, yoga, homoeopathy, reflexology and massage.
Introduction : Ovarian cancer accounts for approximately 4% of all cancers occurring in women and ranks the fourth most frequent cause of cancer-related death in women. Despite aggressive treatment modalities the 5 year survival rate remains less than 30%'. Almost 2.5% of all live births/ year result from assisted reproductive techniques (ARD2. Concern has been expressed that exposure to fertility drugs (FD) might be associated with a risk of ovarian tumors. Given the grave prognosis of ovarian cancer and the increasing use of ART, for the past several years this has been a subject of much scientific debate. The likely magnitude of risk may be 2 - 3 times that of the general population, which is at most 4-5% in a woman's lifetime. Several case control and cohort epidemiological studies have attempted to address this issue but failed to specifically look at drug treatment as risk factor and research to date demonstrates conflicting results.
Review of literature : Ovulation induction (Ol) agents are commonly used in the treatment of infertility in patients with or without ovulatory disturbances. These agents include clomiphene citrate (CC), bromocryptine, gonadotropins (Gn), Gonadotropin releasing hormone (GnRH) and its analogues. In in vitro fertilization (IVF), combinations and different drug dosages of FD are given to stimulate production of multiple oocytes. Fertility drugs were first marketed since the 1960's. The first to hit the market was CC in 1967 followed 2 years later by human Menopausal Gonadotropin (hMG) & human Chorionic Gonadotropin (hCG)'. Until 1987, most IVF cycles used CC in combination with HMG followed by hCG. From 1987, GnRH agonists were introduced to replace Cc. From 1990, the main drug regimen was GnRH agonist in combination with HMG or Follicular Stimulating Hormone (FSH) followed by hCG.
Surgery induces a 'stress' state leading to post-operative hyperglycaemia. To investigate this effect on patients with Type 2 Diabetes Mellitus, we reviewed the records of 50 diabetic patients who underwent surgery without intraoperative insulin. Demographic features together with pre-operative and post-operative blood glucose readings were noted. 27.3% of patients with well controlled pre-operative blood glucose levels developed post-operative hyperglycaemia. In contrast, 84.6% of patients with poorly controlled levels developed the same. Poor control of blood glucose and duration of operation were the only significant predictors of post-operative hyperglycaemia.
From the beginning of time, man has lived in a continuous state of interdependence with his environment. If the forces of nature are harnessed well, they are a source of great benefit to mankind, but when this balance is tipped, nature's backlash on man can be quite devastating. In recent times, we have seen many vivid examples of the magnitude of the destructive forces of nature, ranging from massive floods caused by typhoons such as Katrina and Rita, the hundreds of thousands of lives lost by the powerful tsunami and the destruction of the environment by the raging forest fires in Spain and California. Yet man has not learnt his lesson. Often greed, at times gross ignorance and more often than not, just indifference to the effects of his actions on the environment result in man upsetting his balance with the environment. In Malaysia, since 1990, the haze has become a predictable annual occurrence, varying only in its severity and duration. The cause being beyond our control, we are unable to prevent it from happening. However, it is within our means to be ready to take the necessary steps to minimize the effects of the haze on the health of Malaysians. In order to be able to give appropriate advice and to allay the anxiety of the general public, it is necessary to have a clear understanding about the various effects of haze on humans.
Pulmonary hypertension in pregnancy is a rare condition but is associated with a high mortality. We report the case of a 29 year old female in early pregnancy with Protein C and S deficiency with recurrent deep venous thrombosis and pulmonary embolism and subsequent secondary pulmonary hypertension. The patient was counselled and consented for termination of pregnancy with tubal sterilization. She was administered continuous spinal anaesthesia with invasive monitoring. The successful anaesthetic management of this condition is described.
A 60-year-old man who presented with nasopharyngitis developed uncontrollable epistaxis following a punch biopsy of the nasopharynx. QuickClot was successfully used to arrest the haemorrhage under general anaesthesia after the usual methods employed to secure haemostasis failed. The haemostatic plug was successfully removed a week later after control of the infection. This case represents the first reported intranasal use of QuickClot. We describe our experience and a literature review on this haemostatic agent.
Acute severe intoxication with carbamazepine is associated with seizures, coma and respiratory depression. Traditionally, charcoal haemoperfusion is used to remove the drug. We present a case of carbamazepine intoxication, successfully treated with three hours of high-flux haemodialysis. Thus, haemodialysis using high-flux membranes is a feasible and effective therapeutic option for carbamazepine intoxication.
A case of rhino-orbito-cerebral mucormycosis is presented showing its aggressive nature and progression of disease. The typical clinical features, neuroimaging and histological findings are highlighted in this report. Amphotericin B and surgical debridement remain the mainstay of treatment. However, associated co-morbidities need to be addressed.
Fibrous dysplasia is an uncommon benign disorder of unknown etiology. Rarely, it presents isolated in the temporal bone. We present three cases of monostotic fibrous dysplasia that involved the entire temporal bone.
The objective of this survey was to obtain a self-reported assessment of the use of information technology (IT) by final year medical students. Two hundred and sixty five students responded to a questionnaire survey. 81.5% of students considered their computer skills adequate, while 87.9% had access to computers outside the campus. Most students reported adequate skills at word processing, e-mailing and surfing the Internet. Fifty three percent of students spent three hours or more each week on the computer. While students indicated a general willingness to access Internet-based materials, further steps need to be taken to increase the use of this method of instruction.
In the Malaysian setting of multi-ethnicity and high BCG coverage, interpretation of Tuberculin Skin Testing (TST) may be difficult. Between January 2001 and December 2003, a retrospective study on all adult patients with documented TST results treated for tuberculosis (TB) in chest clinics of two government hospitals was conducted to determine the reliability of TST and factors affecting its interpretation. One hundred and three patients [mean age (SD): 43 (17); male: 67%] were eligible for data collection: 72% and 57% of patients had positive TST results based on cut-off points of 10mm and 15mm respectively. The only significant univariate association with TST results was the severity of co-morbidity. A patient with co-morbidity score of 3 defined as those with any cancer, end-stage renal or liver disease, or HIV disease, was more likely to have a negative TST results [10mm cut-off point: Odd Ratio (95% CI) 6.6 (1.82 to 24.35), p = 0.003; 15mm cut-off point: 4.8 (1.21 to 18.95), p = 0.012]. A TST reading of 10mm had a higher sensitivity than 15mm as the cut-off point in diagnosing TB infection. Considering all possible confounding factors like ethnicity, prior BCG vaccination and TB burden in the population, severity of co-morbidity remains strongly predictive of a negative TST. Caution should be exercised in interpreting TST in these patients.

The in-vitro susceptibility of quinupristin/dalfopristin, levofloxacin and moxifloxacin against methicillin-resistant Staphylococcus aureus (MRSA) strains, which are also resistant to fusidic acid and rifampicin were carried out to determine whether these antibiotics can be used as an alternative treatment for multiply resistant MRSA strains. The minimum inhibitory concentrations (MIC) of these antibiotics were determined by E-test. Quinupristin/dalfopristin had good activity (MIC90 = 1 mg/L) against these strains while most of the strains showed intermediate resistance to moxifloxacin with MIC90 = 2 mg/L). However, more than 90% of these strains were resistant to levofloxacin with the MICs that ranged from 8 mg/L to 16 mg/L with the majority inhibited at 8 mg/L.
Health care workers (HCW) are at higher risk of acquiring blood borne infections such as hepatitis B virus, hepatitis C virus and human immunodeficiency virus from patients. To minimise exposure, Universal Precautions Policy guidelines were introduced. This study looked into one of the aspects of hepatitis B prevention among HCW in the Malaysian context. The objective of this study was to assess hepatitis B vaccine coverage among HCW. A cross sectional study involving pre-tested questionnaires was undertaken from February 2001 to August 2001. Hospital staff in Hospital Kuala Lumpur and Hospital Universiti Kebangsaan Malaysia as well as undergraduate students undergoing clinical attachments were randomly chosen. A total of 625 subjects were enrolled. Only 58.4% had taken a complete hepatitis B vaccination. However, 82.2% have taken at least one dose of the hepatitis B vaccine and were supposed to complete the schedule in due course. Not all HCW were protected against hepatitis B. Preventing hepatitis B in HCW should be one of the priorities of the hospital management as it is definitely cheaper than managing chronic hepatitis B cases.
