A 27-year-old man presented with a two-week history of central colicky abdominal pain associated with loose stools. Further history revealed that he had been exposed to contaminated waters. Stool investigation by direct wet stool smears revealed the presence of Entamoeba histolytica and Blastocystis hominis cysts. A diagnosis of amoebiasis secondary to E. histolytica and concurrent B. hominis infestation was made. We would like to emphasise the importance of clinical history including recent travel to endemic areas. Any suspicion of parasitic infection should prompt the clinician to investigate. Early diagnosis and management would prevent serious complications associated with E. Histolytica infection.
A 28-year-old Malay woman presented with severe loss of vision in both eyes associated with periocular pain on eye movement. She was completely blind at presentation and examination showed optic discs
swelling. Optic nerve imaging showed ‘doughnut sign’, characteristic of optic perineuritis. Steroid was
given over six months. Visual function improved gradually and was maintained at one year follow-up.
This case highlights the importance of differentiation between optic neuritis and optic perineuritis as
visual recovery depends on prolonged management with corticosteroid in optic perineuritis.
Osteomas are benign bone tumors which arise from the cortex or medulla of craniofacial and jaw bones. They are usually asymptomatic or present as slow-growing painless masses. Larger lesions may present with aesthetic (facial asymmetry) and functional disturbances (jaw deviation, difficulty in breathing, pain, and sensory deficits). This paper highlights a case of solitary peripheral osteoma composed of a compact bony mass arising from the lower border of the mandible in an adult female patient. The lesion presented with discomfort during deglutition, which was attributed to impingement of muscles of the oral cavity floor, including the anterior belly of digastric muscle.
Plunging epidermoid cyst of the floor of mouth is indeed an uncommon entity. A 34-year old Malay
gentleman had presented to our centre with a floor of mouth lesion that extended into the submental
region. Clinical findings and imaging studies pointed towards the impression of a plunging ranula.
Histopathological examination of a completely excised mass via intraoral approach, confirmed the
diagnosis of an epidermoid cyst. He was well on follow up with no subsequent recurrence. We discuss
the nature of epidermoid cyst and its surgical management.
Manual workers in plastics industry are often exposed to work related discomfort and pain while performing their daily
task. These exposure leads to common occupational diseases such as Work-related Musculoskeletal Disorder (WMSD) or
low back pain (LBP) which in turn will affect their working performance. The main objective for this study is to
analyse the working posture of a manual worker that works in a polypropylene fibrillated yarn industry using RULA
assessment in CATIA P3 V5R14 software. The subject were selected from the packaging area as the manual handling
work are only present in that area. Based on the RULA analysis done by constructing the worker posture in the
software, several awkward postures were identified to be high in risk factors. The postures that is high in risk is
postures 3 which is due to lifting heavy loads and twisting or turning of the trunk. The postures obtained the final
RULA analysis score of 7 and this indicates that changes must be done immediately. It is recommended that the
company should increase the ergonomic awareness among the manual workers especially while performing their work
and to redesign the working posture for the manual workers.
This An Ergonomic hazard often exists in any industry. However, majority of the employees are not aware of practicing good body posture until the MSDs symptoms become permanent and chronic. The main objective of this study is to determine the manual handling problems among workers at an electronic component manufacturing company. The scope of this study focused on the study entire body disorders among workers on electronic manufacturing company using the Rapid Entire Body Assessment (REBA). A cross sectional study involving observation of the workplace, the work task and the working environment, photographs and videos taken during the observation. Later, a survey questionnaire was given to the respondents to obtain their socio-demography information, work activity and health problems. Rapid Entire Body Assessment (REBA) was conducted on all respondents to determined REBA scores in different work positions. The study was conducted at an electronic component manufacturing company located in Klang Valley, Selangor. A total of 124 workers were surveyed and REBA assessment was performed on 20 workers at Company X production area. It includes 5 categories of position at Company X, such as:loading steel bar into casing; pushing the steel bar, turning movement while adjusting the steel bar, adjusting steel bar into the loading area, unloading steel bar from casing into the machine. The study found that turning section has the highest MSDs problems regarding manual handling because majority of the respondents in the turning department felt the pain while performing their work. This is due to their job demand, which they need to handle with tools weighing from 200 to 400 kg. The REBA scores showed that17 out of 20 respondents performing turning operations, moving and pushing the steel bar recorded the highest score of 11 or more which are categorize in the very high risk group. The position of pushing and turning steel bar while moving the steel bar has higher risk that contributed to the ergonomics risk factor, which in-turn can contribute to Muscular Skeletal Disorders (MSDs). More detailed investigation and remedial measures should be taken immediately, especially for the workers performing the manual handlings activities.
Fungal ball is an extramucosal mycosis. The patient may present with facial pain, nasal blockage, purulent nasal discharge and cacosmia, the fungal ball being present unnoticed for years. Some patients do present as having other nasal problems and later on are found out to have a fungal ball incidentally. We present a case of 38 yearold man who was clinically diagnosed as having left antrochoanal polyp. Intraoperatively, a fungal ball was discovered in the left maxillary antrum.
Neck abscess is still common in developing countries. Often the presentation is late especially when the pain becomes intolerable or the airway is compromised. Intramuscular abscess in the neck is very rarely encountered. We report a case of an abscess of the right sternocleidomastoid. The culture grew Proteus mirabilis. The outline of management is discussed.
In a clinical controlled trial involving repeated measures of continuous outcomes such as quality of life, distress, pain, activity level at baseline and after treatment, the possibilities of analyzing these outcomes can be numerous with quite varied findings. This paper examined four methods of statistical analysis using data from an outcome study of a clinical controlled trial to contrast the statistical power on those with baseline adjustment. In this study, data from a CCT with women with breast cancer were utilized. The experiment (n=67) and control (n=74) were about equal ratio. Four method of analysis were utilized, two using ANOVA for repeated measures and two using ANCOVA. The multivariate between subjects of the combined dependents variables and the univariate between subjects test were examined to make a judgement of the statistical power of each method. The results showed that ANCOVA has the highest statistical power. ANOVA using raw data is the least power and is the worst method with no evidence of an intervention effect even when the treatment by time interaction is statistically significant. In conclusion, ANOVA using raw data is the worst method with the least power whilst ANCOVA using baseline as covariate has the highest statistical power to detect a treatment effect other than method. The second best method as shown in this study was in using change scores of the repeated measures.
This report describes an unusual case of multidrug resistant tuberculosis (MDR-TB), involving the right clavicle and multicentric aytpical spine involvement without any neurological deficit. The female patient presented with acute onset of right clavicular pain associated with a one-monthhistory of lower backache with constitutional symptoms. The clavicular lesion and MRI spine findings were highly suggestive of TB. Anti TB drugs (ATD) were started empirically as Sabah, Malaysia the patient’s home, is anendemic area for TB. Despite, 2 months of ATD administration, the patient did not respond well clinically and developed left sided chest wall abscesses arising from the left 3rd and 6th ribs. She was then treated for MDR-TB infection and has responded well to this treatment.
We report a rare case of undifferentiated (embryonal) sarcoma of the liver in a six-year-old girl who at presentation, had fever, right hypochondrium pain and hepatomegaly. The diagnosis was clinched by fine needle aspiration cytology and was subsequently reconfirmed by histopathological examination of the resected tumour. Pre-operative chemotherapy was given because primary resection was deemed not possible. The patient underwent a successful extensive hepatectomy followed by continuation chemotherapy
Introduction: Back pain associated with sense of pain and less comfort in back part of the body especially at the lower back area. Back pain is an occupational health problem with significant impact to productivity of workers.
Methodology: A cross sectional study was conducted to study the prevalence of back pain towards individual, physical and psychosocial factors associated among body shop’s operators at national Automotive Manufacturers.
Result: A total of 32 operators were involved in this study. Nordic Musculoskeletal questionnaire has been used in this study and body position assessment was done by using Ovako Working Posture Analyzing System (OWAS) method. Study showed the prevalence of back pain among operators throughout their work and in the last 12 months was 93.8% and 87.5% respectively. There are significant association (p0.05) between prevalence of back pain with another individual, physical and psychosocial factor.
Conclusion: This study shows that back pain prevalence were influenced by types of activity and body posture during working at assembling division among workers. Attention should be given to ergonomics factors to prevent back pain incident among automotive industry assembly workers.
The aim of the study was to research the use of a simple neural network in diagnosing angina in patients complaining of chest pain. A total of 887 records were extracted from the electronic medical record system (EMR) in Selayang Hospital, Malaysia. Simple neural networks (simple perceptrons) were built and trained using a subset of 470 records with and without pre-processing using principal components analysis (PCA). These were subsequently tested on another subset of 417 records. Average sensitivity of 80.75% (95% CI 79.54%, 81.96%), specificity of 41.64% (95% CI 40.13%, 43.15%), PPV of 46.73% (95% CI 45.20%, 48.26%) and NPV of 77.39% (95% CI 76.11%, 78.67%) were achieved with the simple perceptron. When PCA pre-processing was used, the perceptrons had a sensitivity of 1.43% (95% CI 1.06%, 1.80%), specificity of 98.32% (95% CI 97.92%, 98.72%), PPV of 32.95% (95% CI 31.51%, 34.39%) and NPV of 61.33% (95% CI 59.84%, 62.82%). These results show that it is possible for a simple neural network to have respectable sensitivity and specificity levels for angina.
A five-year-old boy presented with a six-week history of scales, flaking and crusting of the scalp. He had mild pruritus but no pain. He did not have a history of atopy and there were no pets at home. Examination of the scalp showed thick, yellowish dry crusts on the vertex and parietal areas and the hair was adhered to the scalp in clumps. There was non-scarring alopecia and mild erythema. There was no cervical or occipital lymphadenopathy. The patient’s nails and skin in other parts of the body were normal.
Introductions: Call center has been defined as a working environment in which uses telephone and computer for the purpose of marketing and manage communication with prospect clients or existing clients (Rocha, Glina, Morinho and Nakasato, 2005; Sprigg, Smith and Jackson, 2003).
Methodology: The study was conducted via observation of working condition and face to face interview with call center operators. Measurement of anthropometrics was also conducted.
Results: Ergonomics issues found at call center were inappropriate work condition and workstation which lead to awkward sitting posture (sitting with forward leaning posture, raised shoulder, feet not supported on floor). Besides that organizational policy which required high job demand and subsequently lead to prolonged sitting and static posture (very minimal posture changes). Combination all these factors lead to musculoskeletal symptoms and the operators reported of having neck, shoulder, upper back and lower back pain compared to other body parts.
Conclusion: The management should embark on organization wide ergonomics management program and should review the current policy and create safe and healthy working environment by providing suitable workstation for the operators in order to prevent musculoskeletal.
Introduction : Nursing is an occupation associated with high risk of developing back pain due to their nature of work practices. The aim of this study was to determine the prevalence of back pain among nurses working in government health clinics and hospitals in Port Dickson and the factors associated with it.
Methods : A cross sectional study was conducted involving 126 nurses working in government health clinics and district hospital in Port Dickson. They were universally sampled. A selfadministered questionnaire, assessing personal and socio-demographic characteristics, back pain, work factors and psychosocial factors.
Results :The prevalence of back pain among nurses was 79.4% and factors that showed significant association were workplace (p=0.026) and carried heavy load (p=0.043).
Conclusion : Where one work and nature of work one does has been shown in this study to be important issues to be considered in helping to manage back pain related to work. It is also recommended that staff need to be encouraged to do exercise to strengthen the back muscles, increase spinal flexibility and blood circulation to the spine as well as need to be reminded regarding ergonomic adjustment at work.
Right iliac fossa pain can often be misdiagnosed as something sinister or benevolent despite assistance with state of the art imaging techniques. This is particularly more challenging in the female gender whereby the error of managing a right iliac fossa pain may approach forty percent. A 66-year-old lady, ten years post-menopause, presented with a week history of progressively worsening right iliac fossa pain. Malignancy was suspected with a palpable abdominal mass. Computed tomography was suggestive of an abscess collection, but a needle aspirate produced brown faecal material suggestive of a diverticulitis. An exploratory appendisectomy revealed a non malignant appendicular abscess. In conclusion, when clinical and imaging assessments are inconclusive, an exploratory laparotomy for a surgical excision is warranted primarily if malignancy is suspected.
Gastro-peritoneal fistula is a rare but serious complication of laparoscopic sleeve gastrectomy with significant morbidity and mortality. We present the case of a 42-year-old man who underwent laparoscopic sleeve gastrectomy for morbid obesity and presented later with a history of chronic epigastric pain and severe reflux. Upper gastrointestinal series showed the presence of a communicating fistula between the stomach and the left hemi-diaphragm and peri-splenic area.
Objective: To compare the fusion rate between autogenous tricortical iliac crest bone graft and hydroxyapatite block graft in anterior cervical discectomy and fusion (ACDF) surgery. Methodology: Retrospective review of cases that underwent ACDF surgery between 2005 and 2008. They were divided into two groups based on the graft material used. Assessment of fusion at 6 months post-surgery was carried out based on the static lateral cervical radiograph. Results: 32 cases were reviewed; 16 in each arm. There were 29 discectomies performed in the hydroxyapatite group as compared to 22 in the iliac crest group. 18 levels in the hydrxyapatite group showed radiological fusion while in the iliac crest group there were 21 levels fused. Seven patients had donor site pain. Conclusion: The fusion rate for autogenous tricortical iliac crest bone graft in anterior cervical discectomy and fusion surgery was 95%, a more superior fusion rate than that of hydroxyapatite block graft which was 62.1%.
According to recently reported outcome studies, functional outcomes after arthroscopic rotator cuff repair are reasonable and comparable to open or mini-open techniques. We report the functional outcomes after arthroscopic rotator cuff repair of 10 consecutive patients. The average age was 53.9(range 46-59) years. There was a significant improvement of the function of the shoulder when the preoperative scores were compared with those at the time of at least six months follow-up (range of 6 months to 18 months). With the UCLA rating scale, the average total score increased from preoperative 9.8 (range, 6-15) to postoperative 32.6 (range,23-35). With the use of ASES shoulder index, the average total score improved from 14.6 range, 1.6-35) to 92.3 (range,66.6 to 100). We concluded that arthroscopic rotator cuff repair is a treatment method in selective patients with symptomatic rotator cuff pathology to alleviate shoulder pain and improve function.
