Boey CC, Yap SB

J Paediatr Child Health, 1999 Jun;35(3):303-5.

PMID: 10404456

OBJECTIVE: To study the prevalence of complaints of recurrent abdominal pain (RAP) among school children aged 11-12 years in a rural setting in Malaysia.

METHODOLOGY: Questionnaires were distributed to all parents and teachers of children aged 11-12 years who attended a small rural school in which all the children were Malays. Complaints of RAP were defined as at least three such complaints occurring over a period of at least 3 months.

RESULTS: One hundred and sixty questionnaires were distributed, of which 148 were returned, giving a response rate of 92.5%. Sixty-one children (41.2%) had RAP. Approximately 45.2% of girls and 35.9% of boys reported having RAP. Compared with children without RAP, there was a significantly larger number of children with RAP (85.2%) who had at least one stress factor (P = 0.0109). There were no significant associations between RAP and total family income (P = 0.0573), a history of abdominal pain in at least one parent (P = 0.1686), a history of abdominal pain in at least one sibling (P = 0.0617), academic performance (P = 0.9967) or the degree of sports participation (P = 0.8469). There was an increased incidence of other systemic complaints in children with RAP when compared with children without RAP.

CONCLUSION: Recurrent abdominal pain was found to be common among 11- to 12-year-old children in a rural Malay school. There was a significant association found between RAP and the presence of stressful events, as well as with the presence of other systemic complaints.

The specific absorbed dose constant: comparison of values published for 60Co photons

Samat SB, Evans CJ

Radiat Prot Dosimetry, 2003;103(4):341-7.

PMID: 12797557

For the specific absorbed dose constant for 60Co photons, three values quoted directly in the literature and two derived indirectly from published information are reported. The three publications giving the direct values mentioned no medium of absorption, whereas the other two specify tissue. A database of the specific absorbed dose constant is generated for each of 14 media namely air, water, bone and 11 types of soft tissue. These values are consistent with the three directly quoted values plus one of the indirectly obtained values. Air is found to be unlikely as the medium for the first three; and appropriate media for these are suggested. For the other two values, the generated database suggests that one is too small to be accurate; while the other is correct for tissue (as stated in the publication). An apparent error of 10(3) is identified in one of the values directly quoted.

Int Dent J, 1996 Apr;46(2):103-7.

PMID: 8930682

In the absence of pre-extraction records, investigators have used various methods to aid in the selection and placement of artificial teeth for complete dentures. Natural tooth position and size provide the dentist with an optimal guide. A study was conducted on a group of ethnic Chinese subjects where direct measurements were made of the arch size and width of the maxillary central incisor on stone casts. The anterior arch width represented by the inter-canine cusp tip distance was 35.74 +/- 2.17mm. The mesiodistal diameter of the maxillary central incisor was 8.85 +/- 0.59mm with a range of 7.60mm to 11.20mm. The results of this study was discussed against other findings on the Caucasian, Nigerian and Malay groups. The significance of artificial tooth selection for dentures was highlighted in relation to the results obtained from the study for the group of Chinese and other races.

The ability of hospitals to fulfil their roles--of information processing and dissemination, and of quality patient care provider--is influenced by the availability of supporting information systems. Using computers in wards, which is a change process, introduces new working practices accompanied by attitudinal and knowledge alterations in the users. This paper suggests that as a practical approach users need to be consulted and assessed prior to the introduction of computers in their work places. A questionnaire survey, the main purpose of which was to determine the potential users' responses and to measure their computer competencies, was sent to 183 nursing staff in several hospitals. Results show that the respondents have slightly positive attitudes towards computers even though 85% of them were computer illiterate. A training strategy is needed to increase competencies and to develop more favourable attitudes, which can be monitored using four training indicators.

The implications of overemphasis on educational and material achievements are noted.

A double-blind comparison of nomifensine and amitriptyline in the treatment of depression

Ong SB, Lee CT

Acta Psychiatr Scand, 1981 Mar;63(3):198-207.

PMID: 7015790

A double-blind study was carried out to compare the efficacy and tolerability of nomifensine and amitriptyline in 17 Malaysian patients with moderate to severe depression. The two drugs did not differ with regard to antidepressant effect but nomifensine-treated subjects report fewer side-effects with no complaints of palpitations. Nomifensine also increases capacity for work and activity.

Nayak SB, Vasudeva SK

Morphologie, 2021 Apr 16.

PMID: 33875370 DOI: 10.1016/j.morpho.2021.03.005

The scrotum is supplied by ilioinguinal, genital branch of genitofemoral, perineal branch of the posterior cutaneous nerve of the thigh and the posterior scrotal branches of the pudendal nerve. We report an extremely rare innervation of the anterior part of the scrotum by the anterior division of the right obturator nerve. The genital branch of genitofemoral nerve did not reach the scrotum. The ilioinguinal nerve did not supply the scrotum. The anterior division of the obturator nerve gave a branch which ascended superomedially in the thigh, crossed superficial to the spermatic cord and communicated with the right ilioinguinal nerve. As it crossed the spermatic cord, it gave a scrotal branch which descended over the spermatic cord and ramified to supply the anterior part of the scrotum. Knowledge of this variation could be important to anaesthesiologists, urologists and surgeons in general.

Morphologie, 2021 Jun 16.

PMID: 34147368 DOI: 10.1016/j.morpho.2021.05.116

Common iliac vein variations are relatively rare compared to the variations of external and internal iliac veins. A rare pattern of formation of common iliac vein by the confluence of four veins is being reported here. The left common iliac vein was formed by the union of left external iliac vein, internal iliac vein, iliolumbar vein and a common trunk formed by the obturator and vesical veins. External iliac vein and obturator veins were connected by a communicating vein. Both external and common iliac veins were respectively medial to the external and common iliac arteries. Knowledge of this variant formation of common iliac vein could be useful to radiologists, gynecologists and orthopedic surgeons.

Accessory slip of flexor digitorum accessorius (Quadratus plantae) muscle surrounding the lateral plantar nerve and vessels

Nayak SB, Vasudeva SK

Morphologie, 2021 Jul 08.

Flexor digitorum accessorius (quadratus plantae) is a muscle of second layer of the sole of the foot. Though it is not a very important muscle in terms of movements or stability of foot, it could pose problems when it presents variations. We observed a novel, accessory slip of flexor digitorum accessorius. The slip arose from the fascia covering abductor digiti minimi muscle and got inserted into the tendon of the flexor digitorum longus muscle. It was supplied by a branch from lateral plantar nerve. The proximal part of this accessory slip surrounded the lateral plantar nerve and vessels. Compression of lateral plantar nerve by this accessory slip might produce symptoms similar to that of tarsal tunnel syndrome and lead to misdiagnosis. The case could be of importance to foot and ankle surgeons and radiologists.

Marine debris: A review of impacts and global initiatives

Agamuthu P, Mehran SB, Norkhairah A, Norkhairiyah A

Waste Manag Res, 2019 Oct;37(10):987-1002.

PMID: 31084415 DOI: 10.1177/0734242X19845041

Marine debris, defined as any persistent manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment, has been highlighted as a contaminant of global environmental and economic concern. The five main categories of marine debris comprise of plastic, paper, metal, textile, glass and rubber. Plastics is recognised as the major constituent of marine debris, representing between 50% and 90% of the total marine debris found globally. Between 4.8 and 12.7 million metric tonnes of consumer plastics end up in the world oceans annually, resulting in the presence of more than 100 million particles of macroplastics in only 12 regional seas worldwide, and with 51 trillion particles of microplastic floating on the ocean surface globally. The impacts of marine debris can be branched out into three categories; injury to or death of marine organisms, harm to marine environment and effects on human health and economy. Marine mammals often accidentally ingest marine debris because of its appearance that can easily be mistaken as food. Moreover, floating plastics may act as vehicles for chemicals and/or environmental contaminants, which may be absorbed on to their surface during their use and permanence into the environment. Additionally, floating plastics is a potential vector for the introduction of invasive species that get attached to it, into the marine environment. In addition, human beings are not excluded from the impact of marine debris as they become exposed to microplastics through seafood consumption. Moreover, landscape degradation owing to debris accumulation is an eyesore and aesthetically unpleasant, thus resulting in decreased tourism and subsequent income loss. There are a wide range of initiatives that have been taken to tackle the issue of marine debris. They may involve manual removal of marine debris from coastal and aquatic environment in form of programmes and projects organised, such as beach clean-ups by scientific communities, non-governmental organizations and the removal of marine litter from Europe's four regional seas, respectively. Other initiatives focus on assessment, reduction, prevention and management of marine debris under the umbrella of international (the United Nations Environment Programme/Mediterranean Action Plan, the Oslo/Paris Convention) and regional organisations - that is, the Helsinki Commission. There are also a number of international conventions and national regulations that encourage mitigation and management of marine debris. However, it is argued that these initiatives are short-term unsustainable solutions and the long-term sustainable solution would be adoption of circular economy. Similarly, four of the sustainable developmental goals have targets that promote mitigation of marine debris by efficient waste management and practice of 3R. As evident by the Ad Hoc Expert Group on Marine Litter and Microplastics meeting, tackling the marine debris crisis is not a straightforward, one-size-fits-all solution, but rather an integrated and continuous effort required at local, regional and global level.

Is this a blast? An illustrated practical review on peripheral blood smear examination in the paediatric patient

Rose G, Heidi Reinhard H, Kahwash SB

Malays J Pathol, 2020 Apr;42(1):37-49.

PMID: 32342929

The morphologic findings on a peripheral blood smear can provide important clues that help establish a diagnosis or guide the workup of many clinical disorders. Finding a blast - whether clinically expected or not - is one of the most impactful of such findings. Pathologists, clinical haematologists, technologists, and trainees in the medical field often feel the need to refer to an illustrated reference when encountering suspected blasts and blast-mimics. This article provides a practical concise resource that demonstrates the morphological features of the various types of blasts and illustrates the cytologic characteristics that help distinguish them from their benign mimickers in the paediatric population.

Fulltext Torsade de pointes and syncopal attacks in a 26-year old woman with congenital complete heart block and prolonged QT interval

Quek DK, Ong SB

Singapore Med J, 1990 Apr;31(2):185-8.

PMID: 2371586

A 26-year old woman with congenital complete heart block and prolonged QT interval presented for the first time with syncopal attacks associated with torsade de pointes in adulthood. Cardioversion followed by overdrive pacing was needed to finally control the unstable rhythm. During episodes of non-capture, paraoxysms of torsade de pointes leading to ventricular flutter were recorded by a 24-hour ambulatory electrocardiographic monitoring. Beta-blockade and permanent ventricular pacing finally abolished both the syncopal attacks and the torsade phenomena. The prognosis of congenital complete heart block associated with QT prolongation resembles that of the Romano-Ward syndrome. Recognition of this variant would facilitate earlier treatment of this rare but potentially lethal disorder.

Fulltext Neuroleptic malignant syndrome with renal and respiratory complications--a case report

Liam CK, Ong SB

Singapore Med J, 1990 Apr;31(2):182-4.

PMID: 1973548

The neuroleptic malignant syndrome is an idiosyncratic reaction to neuroleptic therapy which sometimes can be fatal because of the various associated complications. We describe a schizophrenic patient who, after commencement of haloperidol, developed this reaction which was complicated by acute oliguric renal failure and aspiration pneumonia. It is mandatory that the patient is treated in a medical intensive care unit once the syndrome is recognised. The management of the neuroleptic malignant syndrome and its complications is discussed.

The nutritional status of children in an urban squatter community in Malaysia

Yap SB, Teoh ST

Asia Pac J Public Health, 1989;3(4):297-300.

PMID: 2517875

An anthropometric assessment was conducted on a sample of 309 children, aged twelve years and below, from an urban squatter community in Kuala Lumpur, Malaysia. The community consists mainly of Malays and Indians and is fairly established with a mean length of residence of about fifteen years. There was not much difference between the two ethnic groups with regard to educational status or income. Most of the residents were unskilled or semiskilled workers employed in factories and government agencies. About 40 percent of the infants and toddlers were found to be wasted, while about one-third of the older children were stunted. There appears to be some association between income per capita and nutritional status.

STUDIES OF ARBOVIRUSES IN WESTERN AUSTRALIA. SEROLOGICAL EPIDEMIOLOGY

STANLEY NF, CHOO SB

Bull World Health Organ, 1964;30(2):221-6.

PMID: 14153411

In order to obtain information on the occurrence of arboviruses in Western Australia, sera from white persons and Australian aborigines and from animals were subjected to antibody estimations with selected viruses as a prelude to virus isolations. The serological evidence shows the presence of group A and group B arboviruses but significant differences in antibody distribution between the two groups. Antibodies to group A viruses, particularly to the Malayan mosquito virus AMM 2354, are present in both the aboriginal and the white populations over the entire territory. Neutralizing antibody to another group A virus, AMM 2021, isolated in Malaya, is found in much lower prevalence, while antibodies to the newly isolated Queensland group A virus, MRM 39, are found only in the Kimberley area. No avian group A antibodies were detected. The prevalence of group B antibodies is high in the northern part of the State and almost non-existent in the central areas. The results indicate the presence of more than one group B virus and the absence of dengue neutralizing antibody in the Australian aborigine. A unique situation exists in central Australia, where all aboriginal sera have group A antibody but none has group B antibody.
