Pectoralis major myocutaneous flap reconstruction of the defect following surgery for oral cancer in fourteen patients is described. The problems and complications encountered have been found to be minimal. Functional and cosmetic results were acceptable.
A case of traumatic chylothorax is presented with its typical clinical presentation. Failure of conservative measures led to a transthoracic ligation of the thoracic duct, with good result.
Carcinoma of the buccal mucosa is the commonest intra-oral malignancy seen in Malaysia. The purpose of this paper is to present 12 patients with carcinoma of the buccal mucosa who were seen by the authors between January 1981 to September 1981. The principal problems are those of late presentation and treatment, these aspects are illustrated, with a view of early return to normal life.
This paper presents four cases of Fournier's gangrene, including one involving a reconstructive procedure using a preputial rotation flap to cover the raw area, to reduce the period of wound healing. Since Fournier's description of Idiopathic scrotal gangrene in 1884, there have been a number of reports on this relatively rare disease but the problem of achieving early healing and epithelialisation remains.
Congenital branchial fistula and their embryology is well described in the literature. The accepted standard treatment method includes stepladder excision for extensive fistulas. This paper presents two cases (Case 1 and 2) which are embryologically typical of second and third arch origin respectively; and a third case (Case 3) which has not been previously described. Case 3 appears to be a hitherto unreported combination of first and second arch origin. Case 1 and 2 were treated via a standard stepladder excision approach. A different newer approach was utilised in Case 3, that is, stripping of the fistulous tract with Myer's vein stripper. Unlike the stepladder approach, this is simple and avoids extensive time consuming dissection. However, being a blind procedure, it is not generally advocated if vital structures exist in the proximity.
Acute puerperal uterine inversion is a life-threatening and unpredictable obstetric emergency. If overlooked, it could lead to a maternal death. Although the precise cause is unknown, it is postulated to be caused by the mismanagement of the third stage of labor with premature traction of the umbilical cord and fundal pressure before placental separation. At the Ipoh General Hospital in Malaysia there were 31 394 deliveries and four acute uterine inversions occurring from 1 January 2002 to 30 June 2005. The four patients were between 25 and 36 years of age and their parities were between two and three. When manual repositioning of the uterus failed, successful correction was accomplished by the O'Sullivan's hydrostatic method. One case had to undergo subtotal hysterectomy after repositioning because of massive hemorrhage secondary to placenta accreta. Early diagnosis, immediate treatment of shock, and replacement are essential.
In 1985, 140 (26.1 %) of 536 admissions to the intensive care unit (ICU) were general surgical cases. Retrospective review of 107 of these admissions revealed four factors to be significantly different between survivors and non-survivors, p < 0.01. They were duration of stay, organ system failure, sepsis and complications. The role of the surgeon in an ICU where management is interdisciplinary is emphasised.
Four cases of anorectal melanoma are presented. The authors believe that this is the first report of the occurrence of this tumour in Malays. Advanced disease at initial presentation accounts for the poor prognosis observed in this series. Surgery remains the principal treatment modality, although controversy exists regarding optimal extent of resection.
In this paper, the method of differentiating asthmatic and non-asthmatic patients using the frequency analysis of capnogram signals is presented. Previously, manual study on capnogram signal has been conducted by several researchers. All past researches showed significant correlation between capnogram signals and asthmatic patients. However all of them are just manual study conducted through the conventional time domain method. In this study, the power spectral density (PSD) of capnogram signals is estimated by using Fast Fourier Transform (FFT) and Autoregressive (AR) modelling. The results show the non-asthmatic capnograms have one component in their PSD estimation, in contrast to asthmatic capnograms that have two components. Furthermore, there is a significant difference between the magnitude of the first component for both asthmatic and non-asthmatic capnograms. The effectiveness and performance of manipulating the characteristics of the first frequency component, mainly its magnitude and bandwidth, to differentiate between asthmatic and non-asthmatic conditions by means of receiver operating characteristic (ROC) curve analysis and radial basis function (RBF) neural network were shown. The output of this network is an integer prognostic index from 1 to 10 (depends on the severity of asthma) with an average good detection rate of 95.65% and an error rate of 4.34%. This developed algorithm is aspired to provide a fast and low-cost diagnostic system to help healthcare professional involved in respiratory care as it would be possible to monitor severity of asthma automatically and instantaneously.
Locally advanced or recurrent carcinoma of the breast poses difficult management problems. These fungating and discharging tumours severely impair the quality of life in these unfortunate patients. We report two cases successfully treated with omental transposition flaps and split skin grafts. The operation is described in detail and the results discussed. This technique was found to be safe, effective and rewarding.
A rare case of hepatic hydatidosis in non-endemic Malaysia is reported. It is important that clinicians treating the occasional patient be familiar with current diagnostic and therapeutic modalities.
The needs for health promotion is increasingly important for Malaysian. Government invests in the development to improve health education. Malaysia lacks the development of online solutions to help to maintain the health of the nation through prevention and mass education. This paper addresses important questions about the development of those health promotion websites by considering the motivation of web elements. It seeks to provide information on the barriers to the use and success as a method of health promotion. The empirical work is a perceptions study that aims to identify the barriers of web-based health promotion in the different user characteristics for health promotion purposes. This work is a qualitative research project directed at ascertaining the perceptions of Malaysians concerning the use of health promotion websites. It pertains to those factors which stop the uptake of website use and seeks to discern the views of users on how the health promotion websites may be more engaging. The principal finding is that the ethnicity of the user is mainly relevant in terms of the socio-economic status of the user. Users across all ethnicities respond to the same qualities of websites. The same web elements are motivating to users regardless of the characteristics of the users because the uptake of the Internet and the use of websites for health promotion has been more a phenomenon of the young. The study concludes with some recommendations for the Ministry of Health and the developers of health promotion websites in Malaysia.
A 31-year old male presented with bone pain, polyuria and a palpable nodule in the neck. Radiological examination showed generalised osteopenia, subperiosteal erosion and presence of bilateral renal stones. The essential chemical pathological changes were increased plasma calcium, mid-molecule immuno-reactive parathyroid hormone (iPTH), human chorionic gonadotrophin (hCG) levels. Surgical excision of the nodule revealed a parathyroid carcinoma. The uniqueness of this case is the steroid-suppressible plasma calcium, iPTH, and hCG levels. The diagnostic implications of the findings are discussed.
