Many reports have been found in the literature regarding the electrophoretic study of various urogenital diseases, but those on syphilis are relatively rare. It is author's opinion that the correlation between syphilis and the dysfunction of various organs must also be elucidated into detail. On this view point the author has studied the total protein and paper electrophoretic fractions of the serum derived from the patients of syphilis in 17 males and 5 females visited our department during the period from October, 1962 to September, 1964 Age distribution was between 18 and 45 years of age and duration of history was from 3 months to 8 months. The results obtained were as follows: 1. Total protein and electrophoretic fractions of 22 patients' serum: a) The amount of total protein decreased slightly. b) Albumin decreased markedly. c) Alpha 1 globulin decreased remarkably. d) Alpha 2 globulin decreased slightly. e) Beta globulin increased very remarkably. f) Gamma globulin increased markedly. g) A/G ratio decreased very remarkably. All of the above patterns were compared with normal rate. 2. Total protein and electrophoretic fractions of same 22 patients' serum in duration 30 days after complete therapy: a) The amount of total protein, albumin alpha 2 globulin, gamma globulin and A/G ratio etc. are unchanged b) Alpha 1 globulin decreased markedly. c) Beta globulin increased slightly. All of the above pattern were compared with normal rate.

In Singapore, chronic care is provided by both ambulatory primary care clinics and specialist clinics in hospitals. In 2005, the National Healthcare Group (NHG) embarked to build a diabetes registry to enhance the continuity of care for patients with diabetes and facilitate greater efficiency in outcome measurement. This Chronic Disease Management System (CDMS) links administrative and key clinical data of patients with diabetes mellitus across the healthcare cluster. At the point of patient care, clinicians view a summary of each patient's chronic disease records, consolidated chart with physical parameters, laboratory investigation results and the "patient reminders" listing the clinical decision support prompts when key laboratory and screening tests are due for each patient. The CDMS provides reports of clinical outcomes in a systematic and efficient manner for quality improvement and evidenced-based population management. These include process indicators consisting of the rates of glycated haemoglobin (HbA1c), low-density lipoprotein-cholesterol (LDL-c) and nephropathy tests; and intermediate outcome indicators of the proportion of patients with poor HbA1c (>9%) and optimal LDL-c (<2.6 mmol/L) control. From January 2007 to December 2008, the rates of the 3 process indicators were relatively unchanged and that of HbA1c and LDL-c tests were high. There was gradual improvement in the proportion of patients achieving target level of LDL-c in both primary care clinics and hospitals. Fewer patients at primary care clinics had poorly-controlled HbA1c. As a tool for chronic care delivery, the NHG diabetes registry has made clinical monitoring and outcome management for patients with diabetes mellitus more efficient.

INTRODUCTIONFunctional magnetic resonance imaging (fMRI) is a neuroradiological technique for the localisation of cortical function. FMRI made its debut in cognitive neuroscience and then eventually to other clinical applications. We report our experience with pre-surgical fMRI on a high field scanner, based purely on a clinical platform.

MATERIALS AND METHODSThe protocols included motor, auditory, visual and language fMRI. The choice of protocols was dependant on clinical request and lesion locale.

RESULTSRetrospective analysis and audit of the fi rst 30 consecutive patients over a 12-month period revealed that about 85% of patients had a successful examination. In a pictorial essay, we demonstrate that patients with weakness in performing a motor task showed abnormal activations of the pre-motor and supplementary motor areas.

CONCLUSIONFMRI data greatly enhances the pre-surgical planning process and the conduct of surgery when it is incorporated into the surgical navigation system in the operating theatre.

In Malaysia, it is a common belief among health care workers that females and Indians have lower pain threshold. This experience, although based on anecdotal experience in the healthcare setting, does not allow differentiation between pain tolerance, and pain expression. To determine whether there is a difference in the tolerance to pain between the three main ethnic groups, namely the Malays, Chinese and Indians as well as between males and females. This was a prospective study, using a laboratory pain model (ischaemic pain tolerance) to determine the pain tolerance of 152 IMU medical students. The mean age of the students was 21.8 years (range 18-29 years). All of them were unmarried. The median of ischaemic pain tolerance for Malays, Chinese and Indians were 639s, 695s and 613s respectively (p = 0.779). However, statistically significant difference in ischaemic pain tolerance for males and females Indian students were observed. Possible ethnic difference in pain tolerance in casual observation is not verified by this laboratory pain model. Difference in pain tolerance between genders is shown only for Indians.

In medicine, it is the physician's obligation to promote and protect the patient's interest. In obstetrics, the ethical principles of beneficence and autonomy provide the fundamental framework which guides the management of all pregnant patients. As there is the need for consideration of the fetus, autonomy can become a complex issue giving rise to what is sometimes called "maternal-fetal conflict." In this paper, we aim to discuss some scenarios we encounter in our day-to-day obstetric practice such as pre-eclampsia, fetal growth restriction and labour induction when the best interests of the mother and fetus may be conflicted. We hope to illustrate that logical consideration for maternal and fetal best interests is only possible when there is adequate knowledge to support clinical practice. Certainly, with the rapid availability of newer knowledge and technology, it is the duty of the physician to be educated continuously so as to protect the patient from harm.

INTRODUCTIONThe management of recurrent traumatic patellar dislocation includes surgical realignment. There is no clear distinction whether proximal soft tissue or distal procedures produce superior results. However, distal realignment procedures are commonly associated with greater morbidity. We advocate a distal procedure only for cases which are more severe, such as the presence of patellar maltracking.

MATERIALS AND METHODSBetween January 2002 and June 2007, all patients who had a history of traumatic patellar dislocation with recurrent symptoms and failed conservative management underwent surgical realignment. Patients who had evidence of lateral patellar subluxation on computed tomography (CT) scan were offered a distal realignment procedure using the Elmslie-Trillat or Roux Goldthwaite procedure. All other patients underwent proximal soft tissue medial patellofemoral ligament (MPFL) reconstruction. Pre and postoperative functional International Knee Documentation Committee (IKDC), Lysholm and Tegner score assessments were performed for a minimum follow-up period of 6 months. The mean scores for each group were analysed using the Wilcoxon Matched-Pairs Signed-Ranks test and the Mann-Whitney U test was used to evaluate the difference between the groups.

RESULTSA total of 23 patients underwent surgery for patellar realignment. Of whom, 14 patients had a distal realignment procedure while 9 patients had a proximal procedure of MPFL reconstruction. There was greater morbidity reported with distal realignment procedures. Pre and postoperative IKDC, Lysholm and Tegner scores showed significant improvement for both treatment arms. However, there was no significant difference between the improvement scores for both groups.

CONCLUSIONPatients with significant patellar maltracking following traumatic patellar dislocation would benefit from distal realignment using the Elmslie-Trillat or Roux Goldthwaite procedure. Otherwise, a proximal soft tissue procedure involving MPFL reconstruction would be adequate. A management algorithm is proposed for clinical use.

Idiopathic Normal Pressure Hydrocephalus (NPH) is a debilitating condition of the elderly. The patient is typically "wet, wobbly and wonky", to different degrees of the triad. The diagnosis is supported by the radiologic finding of dilated ventricles, determined by an elevated Evan's Index (EI) without a demonstrable cause. Patients with newly diagnosed NPH typically respond to ventriculo-peritoneal shunting (VPS). NPH-related dementia is possibly the only surgically reversible dementia. An elevated cerebrospinal fluid (CSF) fl ow rate (FR) is associated with a positive response to shunting. However, post-shunting EI and FRs are unpredictable. Of late, intracranial apparent diffusion coefficient (ADC) quantification via Diffusion Weighted Imaging (DWI) has been emerging as a possible marker in NPH diagnosis. A local study, conducted on a national level, to study the relationship of EI, FR and ADC to pre- and post-shunt clinical measurements has just ended. This review seeks to reconcile the current thinking of NPH, magnetic resonance imaging (MRI) quantification and clinical evaluation, and in the process shed some light on major pathophysiological determinants of the disease.
