    In a retrospective study of giant breast masses over a period of 20 years (1980-2000), we encountered 18 patients with fibroadenomas. Most of them were adolescents and young adults. The bimodal age incidence seen in Caucasians was not observed. The masses ranged from 6 to 15 cm in size and in the youngest patient, they were bilateral. All 18 patients were examined by mammography and 10 of them by ultrasonography (US) as well. The right breast was involved in 12 patients and the left in six. The diagnosis was confirmed pathologically in all patients, by excision biopsy in 17 patients and by fine needle aspiration cytology and excision biopsy in one patient. The radiological findings were the same as those previously described. All patients were treated by simple enuculation. There was only one recurrence over a follow-up period from 2 months to 3 years.

    Maternal and fetal blood gas values were studied in 90 selected mothers of comparable age, weight, duration of pregnancy and hematocrit values undergoing cesarean section under balanced general anesthesia in four differing clinical situations: elective with and without placental dysfunction, and emergency with and without fetal distress in apparently normal mothers. Pre-induction (Fi O2 0.21) and pre-delivery (Fi O2 0.60) maternal blood gas analysis, along with umbilical cord blood gas analysis were performed in all cases. Apgar scoring was carried out at one minute and three minutes and correlated with the blood gas values. Out of the 90 cases studied, 36 neonates (40%) showed good apgar scores of greater than seven at one minute and three minutes and correlated well with maternal blood gas values which were within normal ranges. Of the remaining 54 cases (60%) with similar mean maternal gas values the neonates showed an apgar score of less than seven in the first minute. The score improved in three minutes in 35 of them (66%), and umbilical cord blood gas values showed a low pH (umbilical vein 7.22 +/- 0.02 units, umbilical arterial 7.21 +/- 0.01 units) but satisfactory pO2 (umbilical vein 39.4 +/- 1.9 torr, umbilical arterial 2.5 +/- 1.3 torr).(ABSTRACT TRUNCATED AT 250 WORDS)

    Analysis on fly artifacts produced by forensically important blowfly, Chrysomya megacephala (Fabricius) (Diptera:Calliphoridae), revealed several unique patterns. They can be divided into fecal spots, regurgitation spots and swiping stains. The characteristics of fecal spots are round with three distinct levels of pigmentation; creamy, brownish and darkly pigmented. Matrix of the spots appears cloudy. The round spots are symmetrical and non-symmetrical, delineated by irregular and darker perimeter which only visible in fairly colored fecal spots. Diameter of these artifacts ranged from 0.5 mm to 4 mm. Vomit or regurgitation spots are determined by the presence of craters due to sucking activity of blowflies and surrounded by thickly raised and darker colored perimeter. The size of these specks ranged from 1 mm to 2 mm. Matrix of the spots displays irregular surface and reflective under auxiliary microscope light. Swiping stains due to defecation by flies consists of two distinguishable segments, the body and tail. It can be seen as a tear drop-like, sperm-like, snake-like and irregular tadpole-like stain. The direction of body and tail is inconsistent and length ranged between 4.8 mm to 9.2 mm. A finding that should be highlighted in this observation is the presence of crater on tadpole-like swiping stain which is apparent by its raised border characteristic and reflective under auxiliary microscope light. The directionality of this darkly brown stain is random. This unique mix of regurgitation and swiping stain has never been reported before. Highlighting the features of artifacts produced by flies would hopefully add our understanding in differentiating them from blood spatters produced from victims at crime scenes.

    The microbes in the gut are crucial for maintaining the body's immune system and overall gut health. However, it is not fully understood how an unstable gut environment can lead to more severe cases of SARS-CoV-2 infection. The gut microbiota also plays a role in the gut-brain axis and interacts with the central nervous system through metabolic and neuroendocrine pathways. The interaction between the microbiota and the host's body involves hormonal, immune, and neural pathways, and any disruption in the balance of gut bacteria can lead to dysbiosis, which contributes to pathogen growth. In this context, we discuss how dysbiosis could contribute to comorbidities that increase susceptibility to SARS-CoV-2. Probiotics and fecal microbiota transplantation have successfully treated infectious and non-infectious inflammatory-related diseases, the most common comorbidities. These treatments could be adjuvant therapies for COVID-19 infection by restoring gut homeostasis and balancing the gut microbiota.

    Scrotal tuberculosis (TB) is rare. Lack of awareness may lead to a misdiagnosis and/or delayed diagnosis of scrotal TB. Clinicians should have a high suspicion index for scrotal TB when facing a patient with a chronic scrotal lump. Since scrotal TB can be medically cured, biopsy of the scrotal lump for pathology study and/or urine polymerase chain reaction (PCR) analysis for M. tuberculosis should be performed first for rapid diagnostic purposes, and therefore unnecessary surgery may thereby be circumvented.

    An aim of medical schools is to select the most suitable candidates who are more likely to become good doctors, fulfilling societal expectations. It is imperative to better understand the influence of 'selection' variables on students' academic performance. We conducted a retrospective record review (3R) to examine the predictive power of pre-admission tracks on academic performance in the medical programme at the Universiti Sains Malaysia.

    Endovascular coiling has been used increasingly as an alternative to neurosurgical clipping for treating subarachnoid hemorrhage secondary to aneurysm rupture. In a retrospective cohort review on the treatment methods of aneurysm rupture in Hospital Kuala Lumpur over the period of five years (2005-2009) a total of 268 patients were treated. These patients were broadly categorized into two groups based on their treatment mode for ruptured aneurysms. Statistical analysis was determined using Chi- Square tests to study these associations. In our study, 67.5% of patients presented with Good World Federation of Neurosurgical Societies (WFNS) grade (WFNS1-2) while 32.5% patients presented with Poor WFNS prior to intervention. In our outcome, it was noted that 60.4% had good functional outcome (mRS grade 0-2) as compared to 39.6% patients who had poor mRS(modified rankin scale) outcome (mRS 3-6). In the good WFNS group, 76% of patients in clipping group had a good mRS outcome while, 86.5% patients in coiling group had good mRS outcome (p=0.114). In poor WFNS presentation, it was noted that in 77.3% patients in clipping group, had poor mRS outcome. Similarly with poor WFNS presentation, 83.3% of patient in coiling group had poor outcome. (p=1.00). Hence when we control the WFNS group, there was no significant association between treatment group (clipping and coiling) and mRS outcome at 6 months. The outcome of patient is determined by initial clinical presentation (WFNS grade) and influenced by requirement of Extraventricular drain (EVD) in presence of hydrocephalus, CSF infection and pneumonia. Therefore the decision regarding treatment option needs to be individualized based on the presentation of the patient.

    A prospective survey on 14 consecutive cases with tuberculous drug induced hepatitis was done at our chest clinic in a state general hospital over a period of 15 months. There were 30 controls chosen randomly from the chest clinic register. The cases had lower mean body mass index (P<0.008), serum albumin (P<0.005) and higher serum globulin (P<0.04). Serum liver transaminases and total bilirubin rose significantly during the acute episode of drug induced hepatitis. Among the risk factors studied, only chronic hepatitis B carrier status was found to be more prevalent among the cases. There was one death (7.1%) over the whole study period.

    A 39-year-old patient developed a disseminated rash with scattered petechiae, fever, malaise and arthralgia after a trip to Malaysia. The patient displayed increasing dengue IgG titers and borderline dengue IgM titers. Dengue fever with a hemorrhagic course is a rare condition in adult patients. Patients who have previously had dengue fever and retained non-neutralizing heterotypic antibodies are more likely to develop this complication via the phenomenon of antibody-dependent enhancement.

    Objectives: To examine the characteristics of maternal filicide and describe the adverse life events experienced by women who have committed filicide and been hospitalised in forensic psychiatric institutions in Malaysia.
    Methods: Registration records from 2000 through 2012 of female patients from 2 main forensic psychiatric institutions in Malaysia were reviewed. The medical records of patients who had committed maternal filicide were selected and descriptively evaluated.
    Results: A total of 18 cases of maternal filicide were identified. Family dysfunction that presented with marital discord, domestic violence, or husband with substance abuse was the main stress experienced by the women. Three social circumstances, including an adolescent who became a victim of date rape; immigrants who experienced sexual abuse; and filicide-suicide precipitated by financial difficulties were highlighted.
    Conclusion: Women who committed filicide had experienced various difficulties in their life. The presence of such life events might alert mental health professionals to investigate the possibility of filicide among their patients.

    Copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] has been the center of attention in the bio-industrial fields, as it possesses superior mechanical properties compared to poly(3-hydroxybutyrate) [P(3HB)]. The usage of oleic acid and 1-pentanol was exploited as the carbon source for the production of P(3HB-co-3HV) copolymer by using a locally isolated strain Cupriavidus sp. USMAA2-4. In this study, the productivity of polyhydroxyalkanoate (PHA) was improved by varying the frequency of feeding in fed-batch culture. The highest productivity (0.48 g/L/h) that represents 200 % increment was obtained by feeding the carbon source and nitrogen source three times and also by considering the oxygen uptake rate (OUR) and oxygen transfer rate (OTR). A significantly higher P(3HB-co-3HV) concentration of 25.7 g/L and PHA content of 66 wt% were obtained. The 3-hydroxyvalerate (3HV) monomer composition obtained was 24 mol% with the growth of 13.3 g/L. The different frequency of feeding carried out has produced a blend copolymer and has broadened the monomer distribution. In addition, increase in number of granules was also observed as the frequency of feeding increases. In general, the most glaring increment in productivity offer advantage for industrial P(3HB-co-3HV) production, and it is crucial in developing cost-effective processes for commercialization.

    Incessant ectopic atrial tachycardia (IEAT) is a rare cause of cardiomyopathy. Cardiomyopathy is reversible by curative ablation using surgery or radiofrequency current. We report our experience with 5 patients with IEAT. Three patients presented with palpitations and were diagnosed to have paroxysmal supraventricular tachycardia (2 patients) and atrial flutter with 1:1 conduction (1 patient), but 2 presented insidiously with congestive cardiac failure. All the initial echocardiograms showed left ventricular dysfunction. The patients underwent electrophysiological studies which confirmed the diagnosis of IEAT. The first patient had surgical cryoablation and the other patients had successful radiofrequency catheter ablation. Follow-up for 2 to 7 years has shown no recurrences. All patients had significant improvement in left ventricular function on echocardiography. In conclusion, curative ablation by surgery or radiofrequency current is safe and effective. Because of its low morbidity, radiofrequency catheter ablation should be the treatment of choice for IEAT, especially if complicated by tachycardia-related cardiomyopathy.

    Pros and cons of Percutaneous Nephrolithotripsy (PCNL) versus Extracorporeal Shockwave Lithotripsy (ESWL) have often been highlighted when one discusses on the management of renal stones. An oft quoted point is that PCNL entails a prolonged hospital stay whereas ESWL sessions are day surgical in nature. However, PCNL has superior stone clearance rate as compared to ESWL especially for lower pole stones. In addition, PCNL is more suitable for large bulk stones and when ancillary procedures are required e.g. endopyelotomy. The first 50 cases of successful tubeless PCNL were reported by Bellman et al in 1997. The remarkable recovery of patients in their series encouraged them to employ this technique as their technique of choice for the majority of their cases. A similar technique was employed on endopyelotomy by Liang et al and they concluded that this was a safe, less morbid and effective technique. We report our first case of tubeless PCNL.

    Bleeding into the rectus sheath is an uncommon but a well-recognised condition that mimics several other diagnoses of acute abdomen. A wide range of etiology has been proposed in association with this condition. It is often self-limiting, but can lead to unnecessary laparotomy if the diagnosis is not recognised.

    Three different methods to measure the oxidative respiratory burst of neutrophils were performed. Of the three, the chemiluminescence technique was observed to be the most sensitive among them. The strong statistical correlation and an acceptable agreement between chemiluminescence with that of the killing assay provides evidence for using the chemiluminescence assay as an alternative method of detecting gross defects of neutrophil respiratory burst killing assays.

    From January 1983 to December 1992 a total of 20,874 salmonella were serotyped in the Bacteriology Division IMR, which showed an increase of 100% compared to the previous ten-years. There were 97 serotypes which belonged to 22 Kauffmann-white groups. Twenty two serotypes hitherto were seen in this study period. S. typhi was the commonest serotype isolated. Overall there was a rise in the isolation of non-typhoidal salmonella particularly S. enteritidis which increased by 760% and S. blockley which increased by 720%. However there is a drop in the isolation of S typhimurium by 223% and S. paratyphi B by 319%.

    BACKGROUND AND OBJECTIVES: The antimicrobial susceptibility pattern of Neisseria gonorrhoeae varies from one country to another and may also change with time. To monitor these variations and changes, it is desirable to have a method that is simple and reproducible. This study was undertaken to determine the in vitro susceptibility of N. gonorrhoeae to azithromycin and to assess the reliability of results obtained using E-test methodology for determination of the minimum inhibitory concentration (MIC) of azithromycin.

    STUDY DESIGN: The MICs for 135 clinical isolates of N. gonorrhoeae were determined by a modified Kirby-Bauer method recommended by the National Committee for Clinical Laboratory Standards against penicillin, cefuroxime, ceftriaxone, norfloxacin, tetracycline, kanamycin, spectinomycin, and azithromycin. The MIC of azithromycin was determined by both the E-test and agar dilution method. All tests were done simultaneously.

    RESULTS: The MIC of azithromycin to all 135 isolates ranged from 0.078 to 0.25 microgram/ml with the agar dilution method and from 0.016 to 0.50 microgram/ml with the E-test. The MIC50 and MIC90 of azithromycin were 0.064 microgram/ml and 0.125 microgram/ml, respectively, by the agar dilution method, whereas they are slightly higher by the E-test method. Seventy-six of the isolates were beta-lactamase producers and 69 were high-level tetracycline-resistant N. gonorrhoeae. There was no difference in the MIC50 and MIC90 of azithromycin in these groups of isolates. The percentage agreement within the acceptable +/-1 log2 dilution difference between MICs obtained by E-test and those obtained by the agar dilution method was 97.8%.

    CONCLUSIONS: Azithromycin has a very good in vitro antigonococcal activity, and the E-test is a reliable method to determine the MIC of azithromycin against N. gonorrhoeae.
