    Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.

  2. Fulltext Relationship of stress, experienced by rescue workers in the highland towers condominium collapse to probable risk factors--a preliminary report
    Saroja KI, Kasmini K, Muhamad S, Zulkifli G
    Med J Malaysia, 1995 Dec;50(4):326-9.
    PMID: 8668051
    The aim of this study was to examine the relationship between the level of stress experienced by rescue workers after the collapse of a 13 story condominium in Kuala Lumpur, and other probable risk factors. Within a month of the incident, 123 firefighters filled up the Impact of Life Event score (Horowitz) and the General Health Questionnaire (GHQ). The results indicated that 7 (6%) firemen could be classified as possible 'cases' on the GHQ, and significantly 5 from this group also scored highly on the impact of events score. No other risk factors were identified in the firemen. On conclusion, the GHQ can be used to screen those with high impact scores to pick up possible cases early enough, so that intervention can be successful.

    PLoS One, 2014;9(1):e86174.
    PMID: 24489695 DOI: 10.1371/journal.pone.0086174
    The objective of this paper is to assess the attitude of Malaysian stakeholders to genetically modified (GM) salmon and to identify the factors that influence their acceptance of GM salmon using a structural equation model. A survey was carried out on 434 representatives from various stakeholder groups in the Klang Valley region of Malaysia. Public attitude towards GM salmon was measured using self-developed questionnaires with seven-point Likert scales. The findings of this study have confirmed that public attitudes towards GM salmon is a complex issue and should be seen as a multi-faceted process. The most important direct predictors for the encouragement of GM salmon are the specific application-linked perceptions about religious acceptability of GM salmon followed by perceived risks and benefits, familiarity, and general promise of modern biotechnology. Encouragement of GM salmon also involves the interplay among other factors such as general concerns of biotechnology, threatening the natural order of things, the need for labeling, the need for patenting, confidence in regulation, and societal values. The research findings can serve as a database that will be useful for understanding the social construct of public attitude towards GM foods in a developing country.

    Resistance training (RT) refers to a method of physical conditioning of complex programming which consists of progressive and various training techniques to achieve the desired training goals. An appropriate programme design is the key to success; where exercise selection is one of the critical factors. The selection of exercise will expose different stimulation as in the application of the specific adaptation on imposed demand principle. The option of choosing either bilateral (BI) or unilateral (UNI) exercise is an important decision to perform in the construction of any strength or RT programme. This study aimed to investigate the physiological responses of unilateral versus bilateral acute RT on heart rate (HR), blood pressure (BP) and rate of perceived exertion (RPE). Sixteen (n = 16) trained women with mean age of 23.31 (SD = 1.35) years old went through a total body exercise session for each unilateral and bilateral protocols which both consisted of major muscles group for 80% 1RM, 10 repetitions to maximal effort for 3 sets. The results revealed that all variables examined including HR, systolic blood pressure (SBP), diastolic blood pressure (DBP) and RPE were statistically changed (p < .001) across the times. Apart from that, unilateral and bilateral RT imposed significantly different stimulus on SBP (p < .05).

    PMID: 34078481 DOI: 10.1017/S0022215121001432
    BACKGROUND: Electronic cigarettes have been a popular alternative to tobacco smoking. The effect of tobacco smoking on nasal airway resistance has been investigated before; however, the effect of the aerosol generated by electronic cigarettes is still unknown. This study aimed to evaluate the short-term effects of e-cigarettes on nasal airway resistance.

    METHODS: Sixty-one participants were recruited into a vapers group and a control group. The vapers group was instructed to smoke for 5 minutes, and their nasal resistance was measured pre-procedure and at 1 and 5 minutes post-procedure. The results were compared between both groups.

    RESULTS: Repeated measures analysis of variance demonstrated that vaping has no statistically significant effect on total nasal airway resistance.

    CONCLUSION: Although the differences between both groups were not statistically significant overall, the vapers group showed a reduction in nasal airway resistance in the short term.

    Nabil S, Nazimi AJ, Nordin R, Hariri F, Mohamad Yunus MR, Zulkiflee AB
    Int J Oral Maxillofac Surg, 2018 Dec;47(12):1511-1518.
    PMID: 30837061 DOI: 10.1016/j.ijom.2018.05.020
    The mandibulotomy is a procedure that was developed to improve access in tumour resection. This study aimed to investigate the complications associated with mandibulotomy and analyze factors that could affect the risks of developing these complications. The hospital records of all patients who underwent a mandibulotomy as part of their tumour ablative surgery at two major centres in Malaysia were reviewed retrospectively. Demographic, clinical, and complications data were recorded and analyzed. Early postoperative complications occurred in 46.5% of the patients and post-radiation therapy complications in 16.1%. Wound dehiscence (27.9%) and inferior alveolar nerve injury (25.6%) were the common early postoperative complications. Dental injuries (9.7%) and plate exposure/infection (9.7%) were the common post-radiation therapy complications. Furthermore, inferior alveolar nerve injury and early abscess formation were significantly associated with the site of the mandibulotomy. The T-stage of a tumour but not the site of mandibulotomy was significantly associated with tumour margin clearance. Mandibulotomy does pose an added risk of complications for a patient undergoing tumour surgery. The benefits of mandibulotomy in terms of gaining margin clearance could not be proven in this study. The site of mandibulotomy appears to increase the risk of developing an inferior alveolar nerve injury.

  10. A seven-year retrospective analysis of the clinicopathological and mycological manifestations of fungal rhinosinusitis in a single-centre tropical climate hospital
    Goh LC, Shakri ED, Ong HY, Mustakim S, Shaariyah MM, Ng WSJ, et al.
    J Laryngol Otol, 2017 Sep;131(9):813-816.
    PMID: 28841131 DOI: 10.1017/S0022215117001505
    OBJECTIVE: To evaluate the clinicopathological and mycological manifestations of fungal rhinosinusitis occurring in the Tengku Ampuan Rahimah Hospital, in Klang, Malaysia, which has a tropical climate.

    METHODS: Records of patients treated from 2009 to 2016 were analysed retrospectively. Data from the records were indexed based on age, gender, clinical presentations, symptom duration, clinical signs and mycological growth.

    RESULTS: Of 80 samples, 27 (33.75 per cent) had fungal growth. Sixteen patients were classified as having non-invasive fungal rhinosinusitis and 11 as having invasive fungal rhinosinusitis. The commonest clinical presentation was nasal polyposis in non-invasive fungal rhinosinusitis patients (p < 0.05) and ocular symptoms in invasive fungal rhinosinusitis patients (p < 0.05). The commonest organism was aspergillus sp. (p < 0.05) in non-invasive fungal rhinosinusitis and mucorales in invasive fungal rhinosinusitis.

    CONCLUSION: There is an almost equal distribution of both invasive and non-invasive fungal rhinosinusitis, as seen in some Asian countries. Invasive fungal rhinosinusitis, while slightly uncommon when compared to non-invasive fungal rhinosinusitis, is potentially life threatening, and may require early and extensive surgical debridement. The clinical presentation of nasal polyposis was often associated with non-invasive fungal rhinosinusitis, whereas ocular symptoms were more likely to be associated with invasive fungal rhinosinusitis.

  11. Fulltext Neutrophil-lymphocyte ratios in the prognostication of primary non-metastatic nasopharyngeal carcinoma
    Liew KY, Zulkiflee AB
    Braz J Otorhinolaryngol, 2017 10 19;84(6):764-771.
    PMID: 29128472 DOI: 10.1016/j.bjorl.2017.09.004
    INTRODUCTION: Nasopharyngeal carcinoma is a geographically and racially variable disease which has a high incidence in Malaysia. Based on current concepts in tumour related inflammation the inflammatory marker, neutrophil-lymphocyte ratio was tested to find its relationship with prognosis in nasopharyngeal carcinoma.

    OBJECTIVE: To investigate the effect of the neutrophil-lymphocyte ratio on prognosis in non-metastatic primary nasopharyngeal carcinoma patients and to further refine the cut off between high and low neutrophil-lymphocyte ratio values.

    METHODS: The medical charts of patients with histologically confirmed nasopharyngeal carcinoma from 1st January 2005 until 31st December 2009 were reviewed retrospectively and theneutrophil-lymphocyte ratio was calculated to see if there was any association between their higher values with higher failure rates.

    RESULTS: Records of 98 patients (n=98) were retrieved and reviewed. Only neutrophil-lymphocyte ratio (p=0.004) and tumor node metastasis staging (p=0.002) were significantly different between recurrent and non-recurrent groups, with the neutrophil-lymphocyte ratio being independent of tumor node metastasis staging (p=0.007). Treatment failure was significantly higher in the high neutrophil-lymphocyte ratio group (p=0.001). Disease free survival was also significantly higher in this group (p=0.000077).

    CONCLUSION: High neutrophil-lymphocyte ratio values are associated with higher rates of recurrence and worse disease free survival in non-metastatic nasopharyngeal carcinoma patients undergoing primary curative treatment.

  12. Fulltext Unusual parapharyngeal lesion: aberrant thyroid gland
    Feisal TK, Prepageran N, Shahrizal T, Zulkiflee AB
    Singapore Med J, 2008 May;49(5):e137-8.
    PMID: 18465039
    An ectopic location of the thyroid gland usually occurs in the midline, starting anywhere from the tongue to the diaphragm. The occurrence of an ectopic thyroid gland in a non-midline site is extremely rare. We report a 32-year-old Malay woman with an aberrant thyroid gland presenting as a parapharyngeal lesion. She had a normally functioning thyroid gland. An ectopic thyroid should be considered as one of the differential diagnoses in the parapharyngeal mass.

    PMID: 30152419 DOI: 10.4103/1319-2442.239656
    Studies among hemodialysis (HD) patients have looked into relationships between illness perception (IP), depression, and adherence yet rarely looked further into medication factors. Those studies were also conducted at urban HD centers leaving out those from a smaller town. Our objective is to determine phosphate binders (PBs) influences on IP and depression among HD population in smaller town. One hundred and thirteen patients from three Central Pahang Cluster Hospitals, Malaysia on HD were interviewed using Malay version of the Brief IP Questionnaire and Beck Depression Inventory II (BDI-II). This study found a significant positive correlation between PBs daily dose frequency with consequence, timeline, and illness concern. Type of PBs used influenced personal control significantly. History of PBs side effects resulted in significantly lower treatment control and lower emotional representation. There was a significant negative relationship between dialysis vintage with both identity and IP score. Depressed patients had significantly higher emotional representation compared to healthy controls. Meanwhile, there was a positive correlation between BDI-II score with coherence, consequence, and emotional representation. Around 23.9% of the patients reported symptoms of depression. Depressed patients had significantly shorter dialysis vintage compared to healthy controls. They tended to report a significant history of hospital admission in the past six months that peaked among those on HD between four to six years. The current study showed the effect of PBs therapy on IP while depression was associated with HD duration and hospital admission. This information can be used to formulate a better treatment approach by health-care practitioners toward better patients treatment hence outcomes.

    PMID: 17682577 MyJurnal
    We report a case of a previously healthy 38-year old lady who presented with prolonged fever and hepatosplenomegaly. Intensive investigations were performed for pyrexia of unknown origin which revealed negative. CT scan of the abdomen showed multiple hypodense lesions which did not respond to broad-spectrum antibiotics. Percutaneous biopsy of the splenic lesion revealed granuloma formation and Langhan's giant cells suggestive of TB. She responded well with anti- TB medication but required extended treatment duration of 24 months due to persistence of the splenic lesion on repeated CT scans. This case illustrates a very rare clinical entity of isolated splenic TB with a therapeutic dilemma following incomplete resolution, despite prolonged treatment.

    Introduction: Although the benefit of low protein diet (LPD) on chronic kidney disease (CKD) progression is well documented, patients’ adherence remains as the main challenge. Therefore, this study sought to identify adherence towards LPD among CKD patients and determine possible associating factors. Methods: This cross-sectional study was done at the Hospital Pakar Sultanah Fatimah in Muar, Johor, among stage III to V CKD patients. Three-day dietary recalls were used to quantify dietary energy (DEI) and protein intake (DPI). Factors investigated include socio-demo- graphic characteristics, medical history, anthropometry and body composition measurements, dietary knowledge, appetite level, handgrip strength, perceived stress, and health locus of control. Associating variables were analysed with logistic regression analysis. Results: The final analysis included 113 patients (54% male) with a mean estimated glomerular filtration rate of 17.5±11.2mL/min/1.73m2 and the average age of 56.3±12.8 years. Mean DEI and DPI were 22.4±5.9kcal/kg/day and 0.83±0.28g/kg/day, respectively. Only 34.5% of patients adhere to the LPD diet with 59% exceeding the DPI recommendation. Poorer LPD adherence was associated with longer duration of hospitaliza- tion (OR 0.707, 95%CI 0.50-1.00, p=0.048), higher energy intake (OR 0.744, 95%CI 0.65-0.85, p

    Objective: The aim of the study was to assess the knowledge, attitudes and practices of students regarding the use of antibiotics in Punjab, Pakistan. Participants: 525 medical and non-medical students from Punjab in Pakistan. Methods: The t-test and ANOVA were used to compare the average response of respondents. Chi-square test was used to measure the association of different elements. Results: The mean age was 20.78 ± 2.10%. About 14% of the students agreed about the appropriateness of antibiotics for viral infections, and 15% of students said they stopped taking the drugs when symptoms subsided. 65.7% of students took antibiotics only when prescribed by a doctor and 54% bought antibiotics without prescription. Statistically significant results were found among the students who had heard about the antibiotic resistance (p

    PMID: 10972033
    Acute respiratory distress syndrome (ARDS) is the final outcome of a common pathway of a variety of unrelated but massive insults to the lung. It is commonly seen in adults but also occurs in the paediatric age group. A prospective study was carried out to determine the incidence, predisposing conditions, clinical course and outcome of children with ARDS admitted to a paediatric intensive care unit (PICU). Six patients (aged 0.8 to 11 years) who fulfilled the strict criteria for ARDS were identified prospectively during a one year study period. The incidence was 1.7% of all PICU admission. The most common underlying conditions were septicemia and pneumonia. The mortality rate was 83%. Death most often occurred during the early phase of the disease. Treatment of ARDS included elimination of the cause of ARDS, early institution of mechanical ventilation with PEEP, prompt recognition and treatment of superimposed infection and careful management of additional organ failure.

    Hasni H, Meah FA, Norlia A, Sharifah NA, Zulfiqar A
    Med J Malaysia, 2004 Oct;59(4):486-94.
    PMID: 15779581
    The aim of the study was: to obtain the profile of patients (with regards to age and family history of breast cancer) with a palpable breast mass. To determine the validity of ultrasound in the assessment of the palpable breast mass by determining the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ultrasound in distinguishing a malignant mass. To determine the most discriminating ultrasound characteristics for differentiating benign and malignant masses. Seventy patients who had fine needle aspiration cytology of a palpable breast mass were subjected to an ultrasound assessment of the mass. The ultrasound findings were classified as benign, indeterminate or malignant. These findings were then compared with either the cytology or histology results in cases that eventually had surgical excision. The age of the patients ranged from 15 to 66 years old The majority was in the third and fourth decades with an average age of 25 years. The 8 patients with a proven malignant breast mass were aged between 39 and 66 years old. They did not have any family history of breast cancer. Only 4 patients had a family history of breast carcinoma and all proved to have a benign breast lesion. Ultrasound had a sensitivity of 100%, specificity of 85.7%, positive predictive value of 50%, negative predictive value of 100% and accuracy of 87.5% for distinguishing a malignant mass. For benign masses: 93.7% had well-defined margins, 81.3% had homogenous internal echoes, 91.7% had depth-width ratio of less than 1.0 and 89% were compressible. For malignant masses: 87.5% had either ill-defined or irregular margins, 87.5% had inhomogenous internal echoes and mixed posterior echoes, and 100% were incompressible. The majority of patients with a palpable breast mass were aged below 40 years old. Most of the patients with a malignant breast mass were aged 40 years and older. Neither a positive nor a negative family history of breast cancer had any significance on outcome. Ultrasound had high sensitivity, specificity and accuracy in distinguishing a malignant mass. The most discriminating benign ultrasound characteristic was compressibility. The most discriminating malignant ultrasound characteristic was ill-defined and irregular margins.

    PMID: 22822637 MyJurnal
    Iatrogenic ureteric injuries are rare complications of abdomino-pelvic surgery but associated with high morbidity from infection and possible loss of renal function. A successful repair is related to the timing of diagnosis, site of injury and method of repair. This study was a retrospective review of outcomes of iatrogenic ureteric injury and factors contributing to successful operative repair. Twenty consecutive cases referred to the Urology Unit of the UKM Medical Center during an 11-year period from 1998 to 2009 were reviewed. Thirteen patients were diagnosed intraoperatively and underwent immediate repair. Seven patients had delayed diagnosis but also underwent immediate repair. In our series, there was no significant difference in outcome between injuries diagnosed intraoperatively versus injuries with delayed diagnosis. There was significant difference in the outcomes between methods of ureteric repair where ureter reimplantation via psoas hitch or Boari flap yielded better results than primary end-to-end anastomosis Three patients suffered loss of renal function from unsuccessful ureter repair. We conclude that all iatrogenic ureteric injury should be repaired immediately in the absence of overt sepsis. Ureter reimplantation using a Boari flap or psoas hitch is preferred to the end-to-end anastomosis especially when there is delayed diagnosis
