Night calls at the doctor's residence are part of the family physician's service to the community. not all night calls are emergencies. Many of the cases can be managed at home if they keep simple remedies at home or they are properly instructed by the doctor. But because some of the calls are medical, surgical or gynaecolofical emergencies, the doctor must respond to all night calls. Some common illnesses necessitating night calls are identified and a list of drugs either to be stocked in the house clinic or in the doctor's emergency bad are identified. Reduction in night calls can be achieved by educating our patients regarding self-management of minor illnesses, use of hospital emergency services, setting up of group practices, a private hospital with emergency service or a community night clinic.
Preliminary work was carried out f o r the development of a rapid method for the detection and enumeration of enterococcal phages in natural water. Eight enterococcal phages were isolated after amplification from water obtained from 2 local ponds. These were plaque-purified and used to test the phage susceptibility of 34 strains of enterococci isolated from pristine and polluted waters. Eight strains with the widest phage susceptibility were used as hosts in a double agar layer (DAL) and a single agar layer (SAL) assay for phage enumeration without pre-assay amplification. N o phages were obtained with the DAL method with all 8 hosts. Usingthe SALmethod, 2 phages were obtained with 1 of the 2 hosts used. Phage isolation was not improved by incubation at 44.5°C. For rapid quantitative testing, the sensitivity of the assays has to be increased to enable phage isolation without the need for prior amplification. KEYWORDS: Enterococci, phage, enumeration
In 1999, the Department of Social and Preventive Medicine set up its website on the Internet (http://ummc.med.uni.edu.my/sps/. Setting up the website was a whole new experience for the author and many new things were learnt along the way. This paper describes how the website was constructed, the problems, and solutions to all these problems. The experience of the author in setting up the SPM website may be useful to others wishing to set up their own department websites. KEYWORDS: Internet, SPM, website, web page
We describe the results of serology for parasitic infection of 698 foreign workers. The 698 foreign workers participated included 115 Indonesians, 387 Bangladeshis, 101 Burmese, 81 Pakistanis, 6 Indians, 3 Thais, 3 Filipinoes and 2 others. Blood samples were taken from these workers and eight tests (Amoebiasis, Echinococcosis, Filariasis (bm and wb), Leishmaniasis, Malaria, Schistosomiasis and Trypanosomiasis) were performed on serum separated from the blood. Among the 698 sera tested, 38.1% were found to be positive for at least one parasitic infection. The most common antibody detected in the positive sera was antibody for amoebiasis (28.1%), followed by malaria (26.9%), echinococcosis (18.1%) and schistosomiasis (11.6%). Other tests showed a low percentage of infection with leshmaniasis (6.5%), filariasis (Brugia malayi (3%) and Wuchereria bancrofti (1%)) and trypanosomiasis (1%).
This study is aimed at determining whether there exists a correlation between the relative dimensions of the nose and the face. Through this study, we hoped to give a normal range for the different races in Malaysia. We randomly chose 100 Malay, 50 Chinese and 50 Indian subjects. We chose equal numbers of male and female subjects, mainly in their 20's and 30's. There is a correlation between the length of the nose and the face among Malays, with 78% of the subjects measured having a nose:face ratio of less than 0.27. There is also a correlation between the breadth of the nose and the face among Malays, with 670/0 of the subjects having a ratio of less than 0.28. Similar correlations were found with Chinese and Indian subjects. The length and breadth of the nose in relation to the face is greater in males than in females. Further research is required before conclusive evidence is found for the existence or non existence of a correlation between the length and breadth of the nose and face in the different races in Malaysia. KEYWORDS: Correlation, length, breadth, nose, nace, different races.
A common practice in psychiatry when treating patients is the concurrent administration of anticholinergics along with antipsychotics, either to prevent or treat extrapyramidal syndrome reactions from occurring. However, most antipsychotics have inherent anticholinergic properties themselves. Therefore, this subtype of these patients have a higher than usual risk of developing anticholinergic side-effects, of which the central nervous manifestations can mimic psychosis, and may cloud judgement on patients' progress towards their treatment.

Skin closure using simple interrupted nylon sutures was compared with closure using subcuticular nylon sutures in 80 consecutive patients undergoing semiemergency surgery, involving open reduction and internal fixation of either the forearm bones or femur. The simple interrupted technique was shown to be slower than the subcuticular technique with higher early postoperative wound complication rate. It may use an extra packet of sutures particularly if the average wound length is 19.8 cm. There is, however, no statistical difference demonstrated for the late scar complaints or subjective and objective scoring of cosmetic outcomes six months after the surgery. KEYWORDS: Simple interrupted, subcuticular, skin closure, nylon, cosmetic outcome
Fosil radiolaria yang terawet dengan agak baik telah ditemui di dalam lapisan rijang yang tersingkap di km 38, lebuhraya Gua Musang-Cameron Highland, berdekatan dengan Pos Blau, baratdaya Kelantan, Semenanjung Malaysia. Sebanyak 20 spesies fosil radiolaria telah dikenal pasti. Spesies ini mewakili zon himpunanPseudoalbaillella globosa yang menunjukkan usia (Roadian) Awal Perm Tengah. Zon himpunan radiolaria ini merupakan rekod biostratigrafi yang baru untuk jujukan batuan bersilika di Pos Blau dan di dalam Zon Sutura Bentong-Raub.
Ionosfera merupakan satu lapisan atmosfera bumi yang mengandungi elektron bebas dan boleh memberi kesan ralat
kepada perambatan gelombang elektromagnetik terutama kepada sistem kedudukan global (GPS). Kesan jumlah
kandungan elektron (TEC) dan fenomena melibatkan sistem suria-magnetosfera-ionosfera-termosfera kepada isyarat
satelit dan komunikasi radio sentiasa berubah. Kajian ini memfokuskan kepada perubahan TEC ketika aktiviti suria
di tahap minimum. Objektif utama kajian ini adalah untuk mengkaji variasi TEC di rantau Malaysia terhadap masa
harian, perubahan musim, aktiviti suria dan medan magnet bumi. Isyarat GPS yang disebarkan pada dua frekuensi
jalur L1 dan L2 mengandungi data kod dan fasa membolehkan pengiraan TEC diperoleh menggunakan GPS. Data GPS
pada tahun 2007 yang diperoleh daripada Jabatan Ukur dan Pemetaan Malaysia (JUPEM), digunakan dalam kajian ini.
Hasil kajian di Asia Tenggara menunjukkan ketika musim ekuinoks, nilai purata TEC dicatatkan tinggi iaitu 35 TEC unit
(TECU) berbanding dengan nilai purata TEC pada soltis yang mencatatkan bacaan 25 TECU. Aktiviti suria didapati lebih
memberi kesan kepada perubahan TEC berbanding dengan medan magnet bumi dengan faktor kolerasi antara aktiviti
suria adalah lebih tinggi iaitu 0.64 berbanding dengan medan magnet bumi iaitu 0.34 sahaja. Kajian ini tertumpu ketika
aktiviti suria di tahap minimum dengan keadaan medan magnet bumi secara puratanya adalah senyap. Ini seterusnya
membolehkan hasil kajian ini menjadi asas kepada maklumat mengenai ionosfera di Malaysia.
