PMID: 21592175 DOI: 10.1111/j.1439-0272.2010.01159.x

The aim of this study was to evaluate the effect of different doses of Malaysian honey on male reproductive parameters in adult rats. Thirty-two healthy adult male Sprague-Dawley rats were randomly divided into four groups (eight rats per group). Group 1 (control group) was given 0.5 ml of distilled water. Groups 2, 3 and 4 were given 0.2, 1.2 and 2.4 g kg(-1) body weight of honey respectively. The rats were treated orally by gavage once daily for 4 weeks. Honey did not significantly alter body and male reproductive organs weights. The rats in Group 3 which received honey at 1.2 g kg(-1) had significantly higher epididymal sperm count than those in Groups 1, 2 and 4. No significant differences were found for the percentage of abnormal sperm, elongated spermatid count, reproductive hormonal levels as well as the histology of the testis among the groups. In conclusion, Malaysian honey at a dose of 1.2 g kg(-1) daily significantly increased epididymal sperm count without affecting spermatid count and reproductive hormones. These findings might suggest that oral administration of honey at this dose for 4 weeks may enhance spermiogenesis in adult rats.

Fulltext Syndrome of inappropriate antidiuretic hormone caused by continuous lumbar spinal fluid drainage after transphenoidal surgery

Norlela S, Azmi KN, Khalid BA

Singapore Med J, 2006 Jan;47(1):75-6.

PMID: 16397727

A 53-year-old acromegalic woman had cerebrospinal fluid rhinorrhoea following transphenoidal surgery for a pituitary microadenoma. A continuous lumbar spinal fluid drainage catheter was inserted and on the sixth postoperative day, she developed hyponatremia with features of syndrome of inappropriate antidiuretic hormone (SIADH) requiring hypertonic saline administration. Over-drainage is potentially hazardous and close biochemical monitoring is required. To our knowledge, this is the first reported case of SIADH caused by continuous lumbar drainage in an adult.

Prepageran N, Subramaniam KN, Krishnan GG, Raman R

Orbit, 2004 Mar;23(1):45-7.

PMID: 15513020

A sphenoid mucocele often presents late due to its deep-seated anatomical site. It has a varied presentation, due to its close relationship to the cavernous sinus and the base of the skull. It can present initially to the ophthalmologist with ocular complaints. In the present paper, the authors present two cases of sphenoid mucocele, one with an isolated third and one with an isolated sixth cranial nerve palsy.

Water pollution during festival periods is a major problem in all festival cities across the world. Reliable prediction of water pollution is essential in festival cities for sewer and wastewater management in order to ensure public health and a clean environment. This article aims to model the biological oxygen demand (BOD(5)), and total suspended solids (TSS) parameters in wastewater in the sewer networks of Karbala city center during festival and rainy days using structural equation modeling and multiple linear regression analysis methods. For this purpose, 34 years (1980-2014) of rainfall, temperature and sewer flow data during festival periods in the study area were collected, processed, and employed. The results show that the TSS concentration increases by 26-46 mg/l while BOD(5) concentration rises by 9-19 mg/l for an increase of rainfall by 1 mm during festival periods. It was also found that BOD(5) concentration rises by 4-17 mg/l for each increase of 10,000 population.

PMID: 38376333 DOI: 10.4103/jcrt.jcrt_1309_21

Malignant melanoma, primarily a cutaneous malignancy, can also involve mucosal surfaces and constitutes 2% to 7% of all gynecological malignancies. Primary melanoma of the uterine cervix is an uncommon tumor and has poor prognosis. In the female genital tract, the synchronous occurrence of primary malignant melanoma in the cervix and vagina is rare. We report a case of a 48-year-old female patient who presented with a blackish vaginal mass and associated growth in the cervix. Biopsy from the vaginal mass was reported as malignant melanoma. Following this, she underwent radical surgery and adjuvant radiotherapy. After 12 months, the patient is doing well.

INTRODUCTION: Information and communication technologies (ICTs) have changed the trend into new integrated operations and methods in all fields of life. The health sector has also adopted new technologies to improve the systems and provide better services to customers. Predictive models in health care are also influenced from new technologies to predict the different disease outcomes. However, still, existing predictive models have suffered from some limitations in terms of predictive outcomes performance.

AIMS AND OBJECTIVES: In order to improve predictive model performance, this paper proposed a predictive model by classifying the disease predictions into different categories. To achieve this model performance, this paper uses traumatic brain injury (TBI) datasets. TBI is one of the serious diseases worldwide and needs more attention due to its seriousness and serious impacts on human life.

CONCLUSION: The proposed predictive model improves the predictive performance of TBI. The TBI data set is developed and approved by neurologists to set its features. The experiment results show that the proposed model has achieved significant results including accuracy, sensitivity, and specificity.

PMID: 3660351

Since thrombi continue to incorporate fibrin during lysis we tested the effect of pretreatment with ancrod, a defibrinating agent from Malaysian pit viper venom, on thrombolysis with urokinase and streptokinase. Thrombi were induced by copper-coils in the carotid arteries of the dogs, weighed after 1 hour and inserted into the femoral arteries of the same animals. They were then exposed for 15 min to iv boluses of streptokinase 10,000 U/kg, urokinase 10,000 U/kg and urokinase 25,000 U/kg with or without pretreatment with ancrod. Ancrod depleted fibrinogen within 5 min and enhanced the lytic effect of streptokinase from 25 +/- 8% to 59 +/- 13% (p less than .05), urokinase 10,000 U/kg from 16 +/- 11% to 66 +/- 18% (p less than .01) and urokinase 25,000 U/kg from 27 +/- 17% to 85 +/- 8% (p less than .001) of the initial thrombus weight. Ancrod itself did not activate plasminogen to plasmin. We conclude that ancrod enhances thrombolysis probably by depleting fibrinogen and preventing new fibrin incorporation into the thrombus during lysis.

Kow RY, Yuen JC, Low CL, Mohd-Daud KN

Malays Orthop J, 2019 Nov;13(3):77-79.

PMID: 31890116 DOI: 10.5704/MOJ.1911.014

Supracondylar humeral fracture is the most common elbow injury in children. It may be associated with a vascular injury in nearly 20% of the cases with a pink pulseless limb. We present a unique case of a paediatric pink pulseless supracondylar humeral fracture, seen late, on the 16th-day post-trauma. Open reduction, cross Kirschner wiring, and brachial artery exploration and repair were performed, and the patient recovered well. Early open reduction and exploration of the brachial artery with or without prior CT angiography was a safe approach in treating patients who presented at 16 days.

It's not just a heartburn and reflux disease: a case report of distal oesophageal spasm and review of literature

Nawawi KNM, Wong Z, Ngiu CS, Raja Ali RA

Med J Malaysia, 2019 12;74(6):540-542.

PMID: 31929483

Distal oesophageal spasm is a rare condition that affects the motility of the oesophagus. It can be diagnosed by highresolution oesophageal manometry and the diagnosis is supported by other modalities such as barium swallow and esophagogastroduodenoscopy examinations. Treatment options include pharmacological therapy, endoscopy and surgical interventions. We described a case of distal oesophageal spasm in an elderly patient who presented with chronic dyspepsia.

Fulltext Suprahyoid pharyngotomy for base of tongue carcinoma

Gopalan KN, Primuharsa Putra SHA, Kenali MS

Med J Malaysia, 2003 Oct;58(4):617-20.

PMID: 15190642

Carcinoma of the tongue remain one of the greatest management challenges for the head and neck surgeon because of the adverse effects of treatment on oral and pharyngeal function. In early carcinoma of the base of tongue however, the prognosis is encouraging and function of swallowing and speech is preserved despite surgery. Suprahyoid pharyngotomy is one of the surgical approaches advocated for resection of base of tongue tumours with primary anastomosis.

Effect of pulping variables on the characteristics of oil-palm frond-fiber

Wan Rosli WD, Law KN, Zainuddin Z, Asro R

Bioresour Technol, 2004 Jul;93(3):233-40.

PMID: 15062817

Caustic pulping of oil-palm frond-fiber strands was conducted following a central composite design using a two-level factorial plan involving three pulping variables (temperature: 160-180 degrees C, time: 1-2 h, alkali charge: 20-30% NaOH). Responses of pulp properties to the process variables were analyzed using a statistical software (DESIGN-EXPERT). The results indicated that frond-fiber strands could be pulped with ease to about 35-45% yield. Statistically, the reaction time was not a significant factor while the influences of the treatment temperature and caustic charge were in general significantly relative to the properties of the resultant pulps.

Fulltext Chronic heel pain: It could be tuberculosis

Muhamad Effendi F, Ibrahim MI, Rozali KN, Miswan MF

Malays Fam Physician, 2016;11(2-3):20-23.

PMID: 28461854 MyJurnal

INTRODUCTION: Heel pain is a common presentation at a primary care setting. The majority of these cases are benign and self limiting in nature. Common differential diagnoses include plantar fasciitis and peroneal muscle sprains. However, certain conditions-if undetected early-may cause significant morbidity to the patient. A high index of suspicion and early referral for further investigations are needed to prevent long-term morbidities.

METHODS: A clinical review of a patient with chronic left heel pain was performed. Blood parameters and imaging investigations indicated chronic infection of the calcaneum. Histopathological examination was highly suggestive of tuberculosis.

RESULT: The patient responded well to antituberculous therapy. She was pain free and showed no signs of recurrence at final follow-up.

CONCLUSION: Here, we report a case of chronic heel pain, which was later diagnosed as tuberculosis of the calcaneum and successfully treated with antituberculous therapy.

PMID: 12440266

Objective: To assess if children with Down's Syndrome have a higher prevalence of otological abnormality compared to their normal counterparts in Malaysia.
Methodology: Thirty children with Down’s Syndrome and normal children underwent otoscope ear examination and impedance test in the ENT outpatients clinic in University Hospital Kuala Lumpur, Malaysia.
Results: The study showed that children with Down’s Syndrome had higher ontological disorders. Forty four percent had impacted wax compared to 14.4% in normal children. Twenty one percent of ears in the study group had refracted drums compared to 6.6% of control. Fifteen percent of ears in the study group had middle ear effusion compared to 3.4% in controls, 55% had a type B tympanogram compared to 8.3% in controls and 73.4% had auditory canal stenosis compared to 14.4% in controls.
Conclusion: Children with Down’s Syndrome thus have a higher incidence of ontological disorders.

Amiodarone-induced phospholipidosis: an in vivo [14C]-acetate uptake study in rat

Sirajudeen KN, Gurumoorthy P, Devaraj H, Devaraj SN

Drug Chem Toxicol, 2002 Aug;25(3):247-54.

PMID: 12173246

Amiodarone (AD), a potent antiarrhythmic drug, is often associated with several adverse effects. It is shown to accumulate phospholipids in various tissues, and the impaired catabolism of phospholipids has been implicated in AD-induced phospholipidosis. The synthesis of phospholipids in tissues has not been dealt with. Hence, the incorporation of [14C]-acetate into phospholipids has been studied to understand the AD-induced phospholipidosis in lung and liver. A significant increase in lung and liver phospholipids was observed after 21 and 28 days of AD (175 mg/kg body weight/day) treatment. In the lung and liver, the incorporation of [14C]-acetate into all phospholipid fractions was elevated, while in the lung mitochondria phosphatidylcholine, phosphatidyl ethanolamine and the cardiolipin levels were significantly increased. The results indicate that, in addition to the impaired catabolism of phospholipid, AD treatment resulted in increased phospholipid synthesis.

Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients.

Effect of cross-fostering on renal anti-oxidant/oxidant status and development of hypertension in spontaneously hypertensive rats

Lee SK, Sirajudeen KN, Sundaram A, Zakaria R, Singh HJ

Clin Exp Pharmacol Physiol, 2011 Dec;38(12):854-9.

PMID: 21973174 DOI: 10.1111/j.1440-1681.2011.05624.x

1. The hypotensive effect of cross-fostering in spontaneously hypertensive rats (SHR) is thought to involve adjustments in renal function. However, its association with renal anti-oxidant/oxidant balance during cross-fostering is not known. 2. The present study examined the effect of cross-fostering and in-fostering of 1-day-old offspring between SHR and Wistar-Kyoto (WKY) dams on renal anti-oxidant/oxidant status and systolic blood pressure (SBP). Renal anti-oxidant/oxidant status and SBP were determined in the offspring from 4-16 weeks of age. 3. Cross-fostered SHR had significantly lower SBP than in-fostered SHR at 6, 8 and 12 weeks, but not at 16 weeks (127 ± 1 vs 144 ± 2, 138 ± 1 vs 160 ± 1, 174 ± 2 vs 184 ± 2 and 199 ± 2 vs 194 ± 3 mmHg at 6, 8, 12 and 16 weeks, respectively). No differences in SBP were evident between cross-fostered and in-fostered WKY rats. There were no significant differences in levels of thiobarbituric acid-reactive substances (TBARS), protein carbonyl and total anti-oxidant status (TAS) or superoxide dismutase, catalase, glutathione peroxidase (GPx), glutathione S-transferase and glutathione reductase activity between cross-fostered and in-fostered SHR or WKY offspring. However, compared with WKY rats, catalase activity was higher at 6 and 16 weeks, TAS was higher at 16 weeks and GPx activity and TBARS were lower at 16 weeks in SHR. 4. It appears that cross-fostering of SHR offspring to WKY dams during the early postnatal period causes a transient delay in the rise in blood pressure in SHR and that this does not involve the renal anti-oxidant/oxidant system.

The effects of prenatal oxidative stress levels on infant adiposity development during the first year of life

Loy SL, Sirajudeen KN, Hamid Jan JM

J Dev Orig Health Dis, 2014 Apr;5(2):142-51.

Although numerous studies have been conducted to examine the causal factors of childhood obesity, the implications of intrauterine oxidative stress on early postnatal adiposity development remain to be elucidated. The Universiti Sains Malaysia Birth Cohort Study aimed to investigate the effects of prenatal oxidative stress levels on the development of infant adiposity during the first year of life. This study was conducted on the healthy pregnant women aged 19-40 years, from April 2010 to December 2012 in Kelantan, Malaysia. Maternal blood samples were drawn in the second trimester to analyse for oxidative stress markers. Infant anthropometric measurements were taken at birth, 2, 6 and 12 months of age. A total of 153 pregnant women and full-term infants were included in the analysis. Statistical test was conducted by using multiple linear regression. Through the infant first year of life, as maternal DNA damage level in the second trimester increased, infant weights at birth (β=-0.122, P<0.001), 2 months (β=-0.120, P=0013), 6 months (β=-0.209, P=0.003) and 12 months of age (β=-0.241, P=0.006) decreased after adjusting for confounders. Similar results were noted when infant body mass index-for-age Z-scores and triceps skinfold-for-age Z-scores were used as the adiposity indicators. In conclusion, the present study shows a consistent inverse association between maternal DNA damage and infant adiposity during the first year of life. These infants with reduced growth and adiposity in early postnatal life may have a high tendency to experience catch-up growth during childhood, which could be strongly associated with later obesity.
