Hypomanic episodes have been reported in two patients who were known to have abused cannabis. The nature of its presentation, possible association and treatment modalities are discussed herewith. A greater awareness of such a condition can put clinicians in a better position to give appropriate treatment imediately, and thus prevent any kind of re-occurrence of such a condition especially in vulnerable patients. KEYWORDS: Cannabis, hypomania.
Antithyroid drugs have been used for more than 50 years for the management of hyperthyroidism. Most patients tolerate treatment well, but some may develop rare life threatening side effects such as agranulocytosis and aplastic anaemia. Clinical experience with the latter condition is extremely limited. We report on a case of carbimazole-induced aplastic anaemia caused by hypocellular bone marrow and associated plasmacytosis in a thyrotoxic patient chronically treated with carbimazole. This resolved after substitution with propylthiouracil. The clinical course was complicated by neutropaenic septicaemia and atrial fibrillation.
Study site: University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia
We report a 33-year-old Malay lady who presented with fever, tonsillitis and pharyngitis a month after initiation of antithyroid therapy (carbimazole 15 mg tds) for thyrotoxicosis by her general practitioner. She was still clinically and biochemically thyrotoxic but not in thyroid storm. At that time, she was also confirmed to be four weeks pregnant. Her full blood count revealed neutropaenia with an absolute neutrophil count of 0.036 × 109/L. Bone marrow aspirate and trephine were compatible with carbimazole-related agranulocytosis. Carbimazole was discontinued and she was given broad spectrum antibiotics and Granulocyte Colony Stimulating Factor (GCSF), to which she responded. Verapamil was used for symptomatic heart rate control instead of beta-blockers as she had a history of bronchial asthma. The patient subsequently opted for termination of pregnancy after which she was given radioactive iodine I131 (10 mCi) for definitive therapy of her thyrotoxicosis. In conclusion, carbimazole-related agranulocytosis is an important entity to recognise and treat early to prevent morbidity and mortality. Termination of pregnancy was carried out as the treatment given during the episode of agranulocytosis may have negative effects on foetal viability and growth.
Cardiopulmonary exercise testing is a non-invasive physiological test which incorporates the conventional method of exercise stress test with a more advanced breath-to-breath ventilatory analysis. The physiological parameters obtained from the test help to illustrate the cardiovascular, respiratory and metabolic responses to physical exertion. Individual's functional capacity and aerobic fitness is reflected by the value of maximal oxygen consumption (VO2 max) obtained from the cardiopulmonary exercise test. This non-invasive and sophisticated test is regarded as a valuable assessment tool in research and clinical practice. Cardiopulmonary exercise test has been extensively utilized to define the mechanisms of exercise intolerance in various clinical disorders, to evaluate responses to therapy and indicate disease prognosis. Emerging data obtained from the use of the cardiopulmonary exercise testing in the research field, has led to its extensive clinical usage. It is now utilized as an integral part of the patients' clinical evaluation in the field of respiratory and cardiovascular medicine, sports medicine, surgery as well as occupational and rehabilitative medicine. It has a clinical role in assessing patient's functional capacity, monitoring disease progression and response to therapy, predicting prognosis, and perioperative morbidity and mortality, as well as constructing and monitoring training and rehabilitative programs. This article aims to give an overview of the physiological profiles obtained from cardiopulmonary exercise testing, its methodological aspects, as well as its utility in research and clinical practice. KEYWORDS: Cardiopulmonary, exercise, physiology, respiratory medicine, oxygen consumption
Night work and rotating shift work are found to be detrimental to the health of workers. A cross sectional analytical study was conducted among the employees of a public medical centre in Kuala Lumpur. A total of 380 employees participated in the health screening and questionnaire survey. The majority of the respondents were Malays, females, and with mean age of 49 years old. The shift workers persistently had higher but non-significant proportions of being overweight/obesity and unhealthy clinical indicators such as systolic and diastolic blood pressure, fasting blood glucose and lipid profile except waist circumferences and HDL-cholesterol. There were also slightly more shift workers diagnosed with diabetes mellitus, hypertension or coronary heart disease (p>0.05). Although the present study could not provide established evidence for a relationship between shift work and cardiovascular risks, this could serve as a pilot study for future studies in this area.
A survey of career choices was conducted for two batches of physicians applying for a medical speciality course in Malaysian medical schools. There were a total of 952 applications, with 477 males and 475 females. Surgery ranked highest, followed by obstetrics and gynaecology, fanlily medicine and orthopaedic surgery. The minor specialities of otorhinolaryngology, psychiatry and pathology were the least popular choices. Questionnaires were sent to a random sample of 250 physicians in each batch to note factors affecting their choices of speciality. A total of 359 physicians responded, giving a response rate of 71.8%. Fixed hours of work and the ability to have direct contact with patients were relatively important factors for choice of speciality. Working as a clinical consultant was the nlost popular nature of employment while worliing in the health office, service consultant in a public hospital, a non-clinical lecturer in a university hospital and working in a private clinic were less popular choices for these physicians. KEYWORDS: Career choice; medical speciality; doctors; Malaysia.
A retrospective study of 102 hands with carpal tunnel syndrome which were treated conservatively initially. Patients who were successfully treated with this method were then compared with those who had failed with this method and had to be treated with surgical decompression. This study found that it took a mean period of about 5.1 months of conservative treatment before deciding on surgery. Generally, the study shows a predominant involvement of the right hand and the female sex as full-time homemakers. Those who finally needed surgery had a longer duration of symptoms prior to consultation. Surgery brought a faster relief from both pain and numbness. It is recommended that conservative treatment be abandoned after a trial period of at least three to five months in order to encourage a speedier recovery.
Phyllodes tumour is a rare entity, affecting mainly middle aged women. It consists of a spectrum of disease
from benign tumour to highly aggressive malignant form. We present a case of massive ruptured malignant
Phyllodes tumour, and its subsequent management.
Epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. It is usually small, asymptomatic, and solitary in lesion. When the size is greater than 5 cm, it is classified as a giant epidermal cyst. If the size is big, it may sometimes mimic a soft tissue sarcoma, hence requiring further evaluation with imaging or histopathological studies. We report a case series of two patients whom presented with a huge swelling at different body regions, involving gluteal and chest. Both patients underwent different modes of imaging to delineate the anatomical extent of the lesion. Excision biopsy was done and the histopathological report confirmed epidermal cyst with no malignancy. The purpose of this case series is to describe the rare occurrence of giant epidermal cyst and to elaborate the methods of approach to arrive at the diagnosis.
Cryptococcus neoformans is an encapsulated fungal pathogen that causes severe disease primarily in
immunocompromised patients. Adherence and internalisation of microbial pathogens into host cells often
begin with engagement of microbes to the surface receptors of host. However, the mechanisms involved
remain poorly understood. In this study, we investigated the association of cell surface determinants of C.
neoformans with mammalian cells. Our results showed that treatment with trypsin, but not paraformaldehyde
or heat killing, could reduce host-cryptococci interaction, suggesting the involvement of cell surface proteins
(CSPs) of C. neoformans in the interaction. We extended our investigations to determine the roles of CSPs
during cryptococci-host cells interaction by extracting and conjugating CSPs of C. neoformans to latex beads.
Conjugation of CSPs with both encapsulated and acapsular C. neoformans increased the association of latex
beads with mammalian alveolar epithelial cells, alveolar macrophages and monocyte-derived macrophages.
Further examination on the actin organisation of the host cells implied the involvement of actin-dependent
phagocytosis in the internalisation of C. neoformans in CSP-conjugated latex beads. We hypothesised that
CSPs present on the cell wall of C. neoformans mediate the adherence and actin-dependent phagocytosis
of cryptococci by mammalian cells. Our results warrant further studies on the exact role of CSPs in the
pathogenesis of cryptococcosis.
Autologous chondrocyte implantation (ACI) is a significant technique that has gained widespread use for the treatment of focal articular cartilage damage. Since its inception in 2004, the Tissue Engineering Group (TEG) of the Faculty of Medicine, University Malaya has been dedicated to carrying out extensive research on this cell-based therapy. The objective of this report, comprising one clinical case report, six animal studies and one laboratory study, is to summarise and discuss TEG’s key findings. On the whole, we observed that the ACI technique was effective in regenerating hyaline-like cartilage in treated defects. Autologous chondrocytes and mesenchymal stem cells (MSC) were found to produce comparable tissue repair irrespective of the state of MSC differentiation, and the use of alginate-based scaffolding and oral pharmacotherapy (Glucosamine and Chondroitin Sulphate) was shown to enhance ACI-led tissue repair. ACI is suggested to be an efficient therapeutic option for the treatment of articular cartilage defects of the knee.
The exclusive breastfeeding rate in Malaysia is very low. However in recent years the awareness of breastfeeding among mothers has increased. A preliminary qualitative research was carried out on these motivated mothers. The objective of this study was to understand the challenges encountered by breastfeeding mothers and to explore the support and motivation received by them. Information from the motivated mothers was obtained from focus group discussion. Some obstacles faced by the mothers were lack of knowledge on breastfeeding and lack of support from health professionals, parents and siblings. Facilities to express breast milk while at work were not readily available. The main motivation to breastfeed came from the mother herself and support from the husband. A holistic approach must be used to help mothers to continue breastfeeding. This includes breastfeeding promotion and education, setting up more Baby Friendly Hospitals, availability of breastfeeding support groups and provision of enough breastfeeding facilities at work and public places.
The records of 141 consecutive patients with proven tuberculosis (TB) were reviewed to examine for changes in their serum proteins, erythrocyte sedimentation rate (ESR) and tuberculin skin test reactivity. Hypoalbuminaemia was present in 73% of patients and hyperglobulinaemia was seen in 92% of patients. ESR showed a negative correlation with the serum albumin level but a positive correlation with the serum globulin level. In the case of pulmonary TB, ESR was higher in patients with radiologically more extensive disease. Tuberculin reactivity was reduced in patients who were older, those with more severe hypoalbuminaemia and those with disseminated TB. KEYWORDS: Albumin, erythrocyte sedimentation rate, globulin, tuberculin reactivity, tuberculosis
Priapism is a urological emergency. The treatment for ischaemic priapism is usually cavernosal aspiration with or without cavernosal irrigation. Some patients may need surgical intervention -the various shunt procedures. We report a 21-year-old man with priapism secondary to chronic myeloid leukemia who needed a combined medical and surgical management. He underwent a spongiocavernosal shunt as well as cytoreductive chemotherapy to achieve complete detumescence. Therefore, cytoreductive chemotherapy is an adjunct in difficult cult to treat priapism associated with chronic myeloid leukemia.
From August 1999 to January 2001, twelve chemotherapy naive patients with locally advanced and metastatic non-small cell lung cancer (NSCLC) in our hospital received vinorelbine and cisplatin. Ten patients had stage IV disease while two had stage HI disease. Patients' performance status (PS) were as follows: four had PS 1, six had PS 2, and one each PS 3 and 4. A total of 46 cycles were given as scheduled. Only major haematological toxicities were noted; one patient each with Grade 3 anaemia, Grade 3 and Grade 4 leucopenia, two had Grade 3 neutropenia and 5 had Grade 4 neutropenia without associated mortality. Three patients had Grade 3 alopecia and one had Grade 3 phlebitis. After three cycles, three patients demonstrated partial response and two had stable disease. For the four patients who completed 6 cycles, two demonstrated stable disease and two partial response. Symptom improvement was reported in all but one patient. Performance status was better in four, stable in six but declined in two patients. In conclusion, in patients with locally advanced and metastatic NSCLC, vinorelbine/cisplatin is a well-tolerated and active regimen, offering symptom palliation and improved performance status in a significant proportion of patients. KEYWORDS; Vinorelbine, lung cancer, chemotherapy.
MRI can be a distressing and traumatic experience in many patients, especially in those with underlying anxiety and/or claustrophobia. We conducted a study to determine if dexmedetomidine as a sedative agent can alleviate these symptoms. Dexmedetomidine is a potent and highly selective α-2 adrenergic receptor agonist which has sedative and analgesic properties. Eleven adult patients (n=11) with a histroy of anxiety and/or claustrophobia undergoing MRI who expressed their desire for sedation were recruited. Dexmedetomidine was infused at 0.5 to 1.0 μg/kg over 10 minutes prior to scanning. Eight patients (n=8) were able to complete the MRI scan comfortably. The findings suggest that dexmedetomidine provides adequate sedation that can allow patients with anxiety and/or claustrophobia to undergo MRI scanning succesfully in a large poproption of the population with anxiety. This result however is still preliminary and will need to be validated in a more robust clinical study.
Malaysia is a country consisting of people of Malay, Chinese and Indian ethnic origin and also of some Indonesian and Thai population. In this study of acute pancreatitis, the age group, sex incidence, clinical
features, complications and treatment were compared between different ethnic groups. A total of fifty-four consecutive patients admitted in Sungai Petani Hospital, Kedah, Malaysia with acute pancreatitis from 2002 to 2004 were taken for this study. There were 29 males and 25 females. The 40–60 years age group was more commonly involved. The common factors associated with acute pancreatitis were alcohol intake in males and biliary disease in females. Two females suffered from acute pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP). One of the 54 cases died due to multi-organ failure.
Evidence-based recommendations on intrapartum care are important to ensure the safety of mothers and neonates. The objective of this study was to compare two established guidelines for intrapartum care to provide clinicians with more comprehensive recommendations on intrapartum management. We carried out a descriptive analysis of guidelines from the Integrated Management of Pregnancy and Childbirth (IMPAC) guidelines published by the World Health Organization, and the Perinatal Care Manual published by the Ministry of Health Malaysia, on intrapartum care to determine differences, if any, with regards to management. Latent, active and the second phase of labour are defined differently in both guidelines. Both guidelines showed high similarity in the steps of clinical management for all phases of labour but differed in foetal monitoring methods, indications for episiotomy, mood and behavior assessment, universal precautions, pain management, and placental disposal. Both guidelines had similar managements for most of the problems encountered during the intrapartum period except for preterm labour and multiple births which have substantial differences. Malaysian guidelines highlight additional systems such as the red alert system, and referral and retrieval system, which would enhance the quality of intrapartum management. The IMPAC guidelines emphasize supportive care, birth companionship, maternal care and monitoring up to one hour after placental delivery; and home birth management; these are inadequately explained or lacking in Malaysian guidelines. From the comparison, it was seen that substantial variation exists in intrapartum management between both guidelines that indicates the need for better evidences to synthesize a more comprehensive set of guidelines for the improvement in intrapartum care.
Background: The cytokine cascade in the immunopathogenesis of malaria infection had been widely studied.
However, their specific association with survival and severe infection remained obscure.
Methods: The study investigated the cytokine profiles and histopathological features of malaria in the severe
infection and survival models by using male ICR mice and male Sprague Dawley rats respectively.
Results: The severe model, the infected ICR mice, exhibited a high parasitemia with 100% mortality after
peak parasitemia at day 5 post-infection. The survival model, the infected Sprague Dawley rats, showed
mild parasitemia with full recovery by day 14 of infection. Both severe and survival models showed similar
histopathological severity during peak parasitemia. The severe model produced highly elevated levels of proinflammatory
cytokines, TNF-α and IL-1α, and low levels of the anti-inflammatory cytokine, IL-4; while the
survival model showed low levels of TNF-α and IL-1α with high levels of IL-4.
Conclusion: There were differences in the pathogenesis of the severe and survival models of malaria infection.
These could be a basis for immunotherapy of malaria in the future.
