Ng KT, Teoh WY, Khor AJ

J Clin Anesth, 2020 Feb;59:74-81.
PMID: 31279283 DOI: 10.1016/j.jclinane.2019.06.027

OBJECTIVES: Melatonin is an endogenous hormone, which regulates circadian rhythms and promotes sleep. In recent years, several randomised controlled trials examining the prophylactic use of melatonin to prevent delirium were published with conflicting findings. The primary aim of this review was to determine the effect of melatonin on the incidence of delirium in hospitalised patients.
DATA SOURCES: MEDLINE, EMBASE and CENTRAL were systematically searched from their inception until December 2018.
REVIEW METHODS: All randomised clinical trials were included.
RESULTS: Sixteen trials (1634 patients) were included in this meta-analysis. Incidence of delirium was not significantly lower in patients who received melatonin, with an odd ratio, OR (95%Cl) of 0.55 (0.24-1.26); ρ = 0.16, certainty of evidence = low, trial sequential analysis = inconclusive. However, patients who randomised to melatonin had a significantly shorter length of stay in intensive care units, with a mean difference, MD (95%CI) of -1.84 days (-2.46, -1.21); ρ

Analgesic use and chronic renal disease in patients with headache

Rahman A, Segasothy M, Samad SA, Zulfiqar A, Rani M

Headache, 1993 Sep;33(8):442-5.
PMID: 8262786

The pattern of analgesic use, abuse and incidence of analgesic-associated nephropathy in 79 patients with chronic headache was studied. Sixty-eight of these patients had migraine. Most patients had consumed a combination of analgesics (81%) while 19% had taken single analgesics for their headache. Nonsteroidal anti-inflammatory drugs were the most commonly used analgesics (96.2%) followed by paracetamol (70.9%) and aspirin, phenacetin and caffeine compounds (5.1%). Mefenamic acid was the commonest nonsteroidal anti-inflammatory drug consumed (97.4%). Analgesic abuse which was defined as a minimum total of 1 kg of analgesics such as paracetamol or aspirin, phenacetin and caffeine compounds or 400 capsules/tablets of nonsteroidal anti-inflammatory drugs was noted in 65 patients. Nonsteroidal anti-inflammatory drugs were the most commonly abused analgesics (89.2%) followed by paracetamol (38.5%). Forty-five of the 65 analgesic abusers had an intravenous urogram or ultrasound performed and renal papillary necrosis was documented in one patient. Three (4.6%) of the analgesic abusers had mildly raised serum creatinine levels. Mild proteinuria of less than 1 gm/litre was present in 27.7% of abusers. In conclusion, although analgesic use and abuse is common in patients with chronic headache, the short term incidence of analgesic-associated nephropathy (2.2%) and renal impairment (4.6%) was low. Prolonged observations will be necessary to ascertain the safety of these drugs for long term use.

Dunson TR, McLaurin VL, Israngkura B, Leelapattana B, Mukherjee R, Perez-Palacios G, et al.

Contraception, 1993 Aug;48(2):109-19.
PMID: 8403908 DOI: 10.1016/0010-7824(93)90002-O

A comparative multicenter clinical trial of two low-dose combined oral contraceptives (OCs) was conducted in Malaysia, Egypt, Thailand, and Mexico. Efficacy, safety and acceptability were investigated in women taking either a norgestrel-based (NG) OC or a norethindrone acetate-based (NA) OC. This paper includes analysis of 892 women, all of whom were at least 42 days but within 26 weeks postpartum and randomly allocated to one of the above OCs. Follow-up visits were scheduled at 1, 4, 8 and 12 months after admission. Baseline sociodemographic characteristics were similar for both groups, as well as compliance. There were nine unintended pregnancies reported; eight of these occurring in the NA group. Adverse experiences were minor with headaches and dizziness being the most common complaints; frequency of reports was similar in both groups. The group taking the NG-based OC had significantly (p < .05) fewer menstrual-related complaints. Discontinuations due to menstrual problems were significantly more common among NA users (primarily amenorrhea). Discontinuations in the NG group were primarily for other personal reasons, e.g. unable to return to the clinic. There was also a significant difference between the two groups for the 11-month gross cumulative life table discontinuation rates due to menstrual problems (p < .01); the NA group had the higher rate.

Volatile organic compounds (VOC), formaldehyde and nitrogen dioxide (NO2) in schools in Johor Bahru, Malaysia: Associations with rhinitis, ocular, throat and dermal symptoms, headache and fatigue

Norbäck D, Hashim JH, Hashim Z, Ali F

Sci Total Environ, 2017 Aug 15;592:153-160.
PMID: 28319702 DOI: 10.1016/j.scitotenv.2017.02.215

This paper studied associations between volatile organic compounds (VOC), formaldehyde, nitrogen dioxide (NO2) and carbon dioxide (CO2) in schools in Malaysia and rhinitis, ocular, nasal and dermal symptoms, headache and fatigue among students. Pupils from eight randomly selected junior high schools in Johor Bahru, Malaysia (N=462), participated (96%). VOC, formaldehyde and NO2 were measured by diffusion sampling (one week) and VOC also by pumped air sampling during class. Associations were calculated by multi-level logistic regression adjusting for personal factors, the home environment and microbial compounds in the school dust. The prevalence of weekly rhinitis, ocular, throat and dermal symptoms were 18.8%, 11.6%, 15.6%, and 11.1%, respectively. Totally 20.6% had weekly headache and 22.1% fatigue. Indoor CO2 were low (range 380-690 ppm). Indoor median NO2 and formaldehyde concentrations over one week were 23μg/m3 and 2.0μg/m3, respectively. Median indoor concentration of toluene, ethylbenzene, xylene, and limonene over one week were 12.3, 1.6, 78.4 and 3.4μg/m3, respectively. For benzaldehyde, the mean indoor concentration was 2.0μg/m3 (median<1μg/m3). Median indoor levels during class of benzene and cyclohexane were 4.6 and 3.7μg/m3, respectively. NO2 was associated with ocular symptoms (p<0.001) and fatigue (p=0.01). Formaldehyde was associated with ocular (p=0.004), throat symptoms (p=0.006) and fatigue (p=0.001). Xylene was associated with fatigue (p<0.001) and benzaldehyde was associated with headache (p=0.03). In conclusion, xylene, benzaldehyde, formaldehyde and NO2 in schools can be risk factors for ocular and throat symptoms and fatigue among students in Malaysia. The indoor and outdoor levels of benzene were often higher than the EU standard of 5μg/m3.

PMID: 24814620

INTRODUCTION: Cervical cancer is the third most common cancer in women worldwide. The HPV-16/18 AS04- adjuvanted vaccine (Cervarix©) has previously been shown to be highly immunogenic with a clinically acceptable safety profile. This phase IIIb, double-blind, randomized (1:1) and placebo controlled trial (NCT00345878) was designed to evaluate the vaccine immunogenicity against HPV-16 and HPV-18 as well as its safety and reactogenicity in Malaysian women.

METHODS: Healthy women aged 18-35 years received intramuscularly three doses of either the vaccine (HPV group) or aluminium hydroxide (ALU group) at 0, 1, and 6 months. Antibody titers were measured by an enzyme-linked immunosorbent assay (ELISA).

RESULTS: A total of 271 eligible subjects were enrolled and 266 subjects completed the study. Initially seronegative subjects in the HPV group showed 100% seroconversion one month post-dose-3 for anti HPV-16 and anti-HPV-18 antibodies with geometric mean titers of 11107.5 (95% CI: 9727.3-12683.4) EL.U/mL and 4273.5 (95% CI: 3771.8-4841.9) EL.U/mL, respectively. Over 96% of subjects in both groups received all three vaccine doses. Solicited local (pain) and general symptoms (myalgia, fatigue, arthralgia and headache) were commonly reported in both HPV and ALU groups. Eight serious adverse events were reported throughout the study (five in the HPV group; three in the ALU group), all considered by investigators to be unrelated to vaccination.

CONCLUSION: The HPV-16/18 AS04-adjuvanted vaccine was immunogenic and generally well tolerated in Malaysian women aged 18-35 years.

Fulltext Functional status and health-related quality of life in patients with primary intracranial tumour

Ooi AL, Mazlina M

Med J Malaysia, 2013 Dec;68(6):448-52.
PMID: 24632911 MyJurnal

This study aimed to evaluate the functional status and HRQoL in patients with primary intracranial tumours in Malaysia. Karnofsky Performance Scale (KPS) and Modified Barthel Index (MBI) were used to assess the functional status whereas EORTC core Quality of Life Questionnaire (QLQ-C30) and Brain Cancer Module (BN-20) questionnaires were used to assess the HRQoL. Thirty-eight patients with primary intracranial tumours admitted for surgery in University Malaya Medical Center were recruited. These assessments were administered before surgery (baseline) and six months after surgery (follow-up). All patients received some form of rehabilitation interventions after surgery. The global HRQoL and functional status of these patients showed improvement at six months after surgery. Emotional Functioning score showed the greatest improvement among the functional domains (63 vs 86, p=0.003). Reduction in symptom burden such as fatigue, nausea, vomiting, pain and headache were also noted at follow-up together with less future uncertainty (p<0.05). Pearson correlation revealed statistically significant positive correlation between functional status and HRQoL at baseline and follow-up, in particular, global health status (r=0.50 and r=0.67), physical functioning (r=0.53 and r=0.90) and role functioning (r=0.34 and r=0.77). Thus, from the correlation found, improving a patient's function and independence level throughout all stages of care, even before any surgical intervention is offered would improve the HRQoL concurrently.

Ali SE, Ibrahim MI, Palaian S

Pharm Pract (Granada), 2010 Oct;8(4):226-32.
PMID: 25126145

OBJECTIVES:
The aims of this study are to determine the prevalence, attitudes and behaviours of medication storage and self-medication amongst female students at Universiti Sains Malaysia (USM).

METHODS:
A cross-sectional survey was conducted and cluster random sampling technique was used for respondent selection. A pre-piloted questionnaire was administered to female respondents so as to collect the data. Data was analyzed using SPSS version 12 and analysis was conducted using descriptive analysis procedures.

RESULTS:
Of the 481 participants (mean age; SD was 22.1; 3.3), 93.1% (n=448) students stated that they stored medicine in their rooms, while 70.7% (n=340) stated that they stopped taking a prescribed medicine without consulting a doctor. The prevalence of self-medication was 80.9% (n=389). The most common reasons for self-medication were related to their knowledge of their ailment and its treatment (58.0%), 14.4% thought it saved time and 8.5% mentioned that medication given by provider was not effective. The most common symptoms were otorhinolaryngology problems (22.5%), followed by respiratory disease (19.6%), Gastro Intestinal Tract (GIT) disease (18.1%) and headache/fever (16.8%). Commonly used medicines were analgesics & antipyretics (30.2%), ear, nose & throat drugs (10.8%), vitamins & minerals (10.8%), GIT drugs (8.5%), anti-infections (7.3%) and herbal medicines (3.5%). Prevalence of medicine storage and self-medication practice is high among educated female students in USM.

CONCLUSIONS:
There is a need to educate the students to ensure safe practice by increasing their awareness. Strict policies need to be implemented on the unrestricted availability of medicines so as to prevent the wastage of medicines.

PMID: 26745297 DOI: 10.1016/j.scitotenv.2015.12.072

This paper studied associations between ocular symptoms, rhinitis, throat and dermal symptoms, headache and fatigue in students by ethnicity and in relation to exposure to chemical microbial markers and fungal DNA in vacuumed dust in schools in Malaysia. A total of 462 students from 8 randomly selected secondary schools in Johor Bahru, Malaysia, participated (96% response rate). Dust was vacuumed from 32 classrooms and analysed for levels of five types of endotoxin as 3-hydroxy fatty acids (C10, C12, C14, C16 and C18 3-OH), muramic acid, ergosterol and five sequences of fungal DNA. Multiple logistic regression was applied. Totally 11.9% reported weekly ocular symptoms, 18.8% rhinitis, 15.6% throat and 11.1% dermal symptoms, 20.6% headache and 22.1% tiredness. Totally 21.1% reported pollen or furry pet allergy (atopy) and 22.0% parental asthma or allergy. Chinese students had less headache than Malay and Indian had less rhinitis and less tiredness than Malay. Parental asthma/allergy was a risk factor for ocular (odds ratio=3.79) and rhinitis symptoms (OR=3.48). Atopy was a risk factor for throat symptoms (OR=2.66), headache (OR=2.13) and tiredness (OR=2.02). There were positive associations between amount of fine dust in the dust samples and ocular symptoms (p<0.001) and rhinitis (p=0.006). There were positive associations between C14 3-OH and rhinitis (p<0.001) and between C18 3-OH and dermal symptoms (p=0.007). There were negative (protective) associations between levels of total endotoxin (LPS) (p=0.004) and levels of ergosterol (p=0.03) and rhinitis and between C12 3-OH and throat symptoms (p=0.004). In conclusion, the amount of fine dust in the classroom was associated with rhinitis and other SBS symptoms and improved cleaning of the schools is important. Endotoxin in the school dust seems to be mainly protective for rhinitis and throat symptoms but different types of endotoxin could have different effects. The ethnic differences in symptoms among the students deserve further attention.

To describe the clinical characteristics and the risk factors associated with mortality in patients with meningitis. This is a retrospective review of patients diagnosed to have meningitis with positive culture of the cerebrospinal fluid (CSF) specimen. All cases aged 19 > years who were admitted to Hospital USM between January 2004 and December 2011 were included in the study. The CSF results database were obtained from the Department of Medical Microbiology and Parasitology, Hospital USM, Kelantan. A checklist was used to record the clinical characteristics. A total of 125 cases met the inclusion criteria. The age of patients ranged between newborn and 19 years old (Mean±SD, 74.5±80.6 months). The majority of them were males (65.6%). Fever was the most common presentation (73.6%) followed by poor oral intake (48.0%), seizure (36.0%) and headache (24.8%). The mortality rate was 31.2%. Coagulase negative staphylococcus was the most frequent pathogens isolated (21.6%), followed by Acinetobacter spp. (17.6%), Staphylococcus aureus (13.6%), Streptococcus spp. (11.2%) and Klebsiella pneumoniae (6.4%). There were significant association of in-hospital death with age (p=0.020) and conscious level (p=0.001). Infectious meningitis is a big health concern, especially among children. We found that coagulase negative staphylococcus, Acinetobacter species, S. aureus, Streptococcus spp and K. pneumoniae were prevalent in our hospital. These microorganisms were hospital associated pathogens. The 31% mortality linked to hospital acquired meningitis specifies the need for focused physician attention especially among younger aged patients.

Shakya R, Shrestha S, Gautam R, Rai L, Maharjan S, Satyal GK, et al.

Patient Prefer Adherence, 2020;14:2287-2300.
PMID: 33244224 DOI: 10.2147/PPA.S270786

Introduction: Hypertension (HTN) is a silent killer, accountable for life-threatening complications. An individual's illness perception may affect adherence to treatment which is crucial to prevent complications of HTN. The objective of this study was to identify illness perception and treatment adherence among patients with HTN in a tertiary hospital in Kathmandu, Nepal.
Methods: Descriptive correlational study was conducted in the out-patient department of Manmohan Cardiothoracic Vascular and Transplant Center, Kathmandu Nepal. Non-probability purposive sampling was used. A face-to-face interview was conducted from September to December 2018, using a structured questionnaire that included socio-demographic variables, illness perception questionnaire (revised) and Hill bone compliance to high blood pressure therapy scale. Data analysis was done by using descriptive and inferential statistics (chi-square test, Spearman rank correlation).
Results: Among 204 participants, 51% were male, 77% were literate, mean ± S.D. age was 60±12. About 72% experienced headache and 88% said that headache is related to HTN. Behavioural factors and psychological factors were regarded as the leading cause of HTN. Almost 63% participants believed HTN as highly threatening illness. Higher scores in timeline (acute/chronic), personal control, and treatment control revealed that patients believed HTN as a chronic disease with a higher rate of personal and treatment control. Regarding treatment adherence, the mean score was 16.58 (SD = 2.08), and only 14.7% had perfect adherence. Participants were more adherent to medication and appointment keeping rather than reduce salt intake. Duration of HTN diagnosis (p=0.027) and duration under HTN medication (p= 0.021) were found to be significantly associated with treatment adherence. There was a significant positive correlation between illness perception and treatment adherence (ρ = 0.282, p<0.01).
Conclusion: Illness perception and treatment adherence are correlated. Hence, it is beneficial to improve illness perception to achieve perfect treatment adherence. Reinforcement is essential to maintain adherence to both medications and behaviour therapy.

Fulltext Cryptococcal Meningitis in an immunocompetent Swiftlet Rancher – first reported case

Tan, Sin Nee, Lim, Thiam Seong Christopher

Malaysian Journal of Medicine and Health Sciences, 2019;15(1):82-84.
MyJurnal

Cryptococcal meningitis is a central nervous system infection cause by Cryptococcus neoformans. Although Cryptococcus is found in bird droppings, it has never been reported for those ranchers involved in the niche swiftlet ranching industry despite having close proximity with the bird droppings. We present here a case of a 41-year-old healthy swiftlet rancher who presents with a history of prolonged fever, headache and altered behaviour of a month duration. Cerebral spinal fluid analysis revealed the presence of Cryptococcus. He was treated with intravenous amphotericin B and flucytosine and discharged well with fluconazole consolidation therapy for 8 weeks, followed by maintenance therapy for 1 year. We believe this is the first reported case of Cryptococcal meningitis (CM) occurring in an immunocompetent swiftlet rancher. This case should highlight the needs to wear a proper personal protective equipment inside a swiftlet ranch due to the constant exposure to the potential cryptococcal-rich environment. A high index of suspicion, careful history taking and physical examination focusing on neurologic assessment is key to early diagnosis and timely management of CM.

Toxoplasmic optic neuropathy is rare and usually occurs monoocularly. This case report demonstrates a rare presentation of bilateral
juxtapapillary retinochoroiditis (Jensen disease) due to toxoplasma infection in
a young healthy patient. A 20-year-old lady presented with bilateral painless
blurring of central vision for 5 days duration. It was preceded by fever, upper
respiratory tract symptoms and headache. There was no history of contact or
being scratched by a cat. Visual acuity was counting fingers for the right eye
and 6/45 for the left eye. There was presence of relative afferent pupillary
defect in the right eye. Optic nerve functions were impaired bilaterally which
was severe in the right eye. Both eyes showed the presence of mild anterior
segment inflammation and vitritis. Fundus examination revealed juxtapapillary
retinochoroiditis bilaterally with swollen optic disc. Optical coherence
tomography (OCT) showed presence of intra-retinal and sub-retinal fluid at
macular area bilaterally. Serology for anti-toxoplasma Immunoglobulin G (IgG)
was positive with titre of 1450 IU/ml. Computed tomography scan (CT scan) of
brain and orbit was normal. A diagnosis of bilateral juxtapapillary
retinochoroiditis or Jensen disease was made. Oral azithromycin 500 mg daily
and guttae prednisolone 4 hourly for 6 weeks was commenced. Oral
prednisolone 50 mg daily (1 mg/kg/day) was added after completion of 1 week
of antibiotic and was tapered down within 5 weeks. There was improvement of
vision as early as 3 weeks post initiation of the treatment. Upon 6 weeks
completing the treatment, her vision has improved to 6/7.5 on both eyes with
resolution of optic disc swelling and sub-retinal fluid. Early recognition and
initiation of treatment in toxoplasma infection associated with juxtapapillary
retinochoroiditis usually result in good visual prognosis.

PMID: 33818409

Co-occurrence of cyanotic congenital heart disease (CCHD) and phaeochromocytoma (PCC) and paraganglioma (PGL) are rare, although some cases have been reported. We report a case of left paraganglioma in a 20-year-old lady with an underlying CCHD who underwent palliative Glenn shunt, subsequently developed polycythaemia and cavernous sinus thrombosis presented with palpitation, sweating, headache and hypertension of 3-months duration at the age of 17. The abdominal CT scan revealed an enhancing left paraaortic mass measuring 5.2 cm x 4.4 cm x 3.8 cm. A 24-hour urine catecholamine demonstrated raised noradrenaline level to six times upper limit of normal and hence diagnosis of left sympathetic (sPGL) was made. In view of the delayed diagnosis and significant morbidity associated with her condition, surgical treatment is no longer an option. Therefore, vigilant screening and early treatment of PCC-PGL in patients with CCHD are crucial in order to avoid significant morbidity and ensure a good quality of life.

MyJurnal

Rhinocerebral mucormycosis is a potentially fatal and progressive angioinvasive fungal infection. It is classically described in patients with uncontrolled diabetes mellitus and hematological malignancies. This report describes a case of progressive rhinocerebral mucormycosis in a patient with poorly controlled diabetes who was on prolonged prednisolone therapy for autoimmune kidney disease. The patient, who was a female, presented to hospital with headache, orbital pain and nasal bridge swelling. Black eschar on nasal mucosae was present on admission. Later, she was started on intravenous fluconazole for the diagnosis of fungal sinusitis. Subsequently, she developed intra- cerebral haemorrhage complicated with transtentorial herniation. Diagnosis of rhinocerebral mucormycosis was later observed by a laboratory finding and the treatment was changed to intravenous amphotericin B. However, the patient succumbed to her illness on the 6th day of hospitalisation. This report discusses the risk factors associated with rhinocerebral mucormycosis as well as the underlying pathogenesis. This report will also highlight the importance of early diagnosis and appropriate treatment for mucormycosis to improve prognosis in patients.

Sarcocystosis is a zoonotic infection that causes intestinal and muscular illnesses in humans. Sarcocystosis was until recently considered rare in humans. To complete their life cycle, Sarcocystis species require both a definitive and an intermediate host. Humans are the definitive host when infected by one of two species: Sarcocystis hominis (from eating undercooked beef) or Sarcocystis suihominis (from eating uncooked pork). Infection with either of these species results in intestinal sarcocystosis, causing a self-limited disease characterized by nausea, abdominal pain, and diarrhea. Humans act as the intermediate host when infected by Sarcocystis nesbitti, resulting in the markedly different clinical picture of muscular sarcocystosis. Most documented cases of muscular sarcocystosis were assumed to be acquired in Malaysia, in addition to other regions of Southeast Asia and India. Published cases of muscular sarcocystosis from the Middle East, Central and South America, and Africa are all rare. Although the clinical presentation of muscular sarcocystosis remains to be fully characterized, fever, myalgia, and headache are among the most common symptoms. Here, we report a patient from sub-Saharan Africa with chronic Sarcocystis myopathy and well-controlled HIV-AIDS.

PMID: 32568285 DOI: 10.4997/JRCPE.2020.213

Vitamin B12 deficiency and folate deficiency are common causes of macrocytic anaemia and both are important for many cellular processes. These deficiencies could be due to inadequate dietary intake, impaired absorption or drug ingestion. We present a case of a 47-year-old male with a history of diffuse large B-cell lymphoma (DLBCL) who was admitted for fatigue, persistent frontal headache and left upper-quadrant abdominal pain. Further investigation showed that he had pancytopenia with microangiopathic haemolytic anaemia (MAHA) and intracranial bleeding (ICB). Serum vitamin B12 and folate were later found to be low and a diagnosis of combined vitamin B12 and folate deficiency mimicking thrombotic thrombocytopenic purpura (TTP) was made. The patient responded well to vitamin B12 and folate replacement.

Food poisoning is still a major problem in the state of Terengganu. The study was conducted during an episode of food poisoning outbreak which occurred in October, 1999, at Universiti Tekonologi Mara (UiTJ1rO, Dungun to determine the etiology, mode of transmission, source and the risk factors of the outbreak and hence to take appropriate remedial actions and preventive measures. A retrospective cohort study was conducted amongst 925 students using a standard questionnaire as well as environmental investigation and bacterial subtyping. All the samples were Malay females, age ranging jrom /9 — 22 years. It was found that majority ofthe victims (72 %) presented with abdominal cramp, 68.5% headache, 60.0% diarrhea, 55.2% fever, 45.0% nausea, 39.0% muscle
ache and 3]. 7% vomiting. The epidemic curve suggested of a common source of infection and the most probable food that has been contaminated was taken during lunch hour on October 20'I'1999, Statistical analysis showed that spices jiied chicken and "nasi minyak" were significantly associated with the illness (p < 0. 05). The most likely causative organism was Salmonella spp as supported by the clinical presentation and incubation period of the disease, identdication of contaminated food, bacterial subtyping result and environmental findings. Following the outbreaks, several remedial actions were taken including immediate close—up ofthe canteen for I4 days, treatment for the cases and health examination and typhoid immunization for all food handlers.
