    BACKGROUND: The Dupuytren disease is a benign fibroproliferative disorder that leads to the formation of the collagen knots and fibres in the palmar fascia. The previous studies reveal different levels of Dupuytren's prevalence worldwide; hence, this study uses meta-analysis to approximate the prevalence of Dupuytren globally.

    METHODS: In this study, systematic review and meta-analysis have been conducted on the previous studies focused on the prevalence of the Dupuytren disease. The search keywords were Prevalence, Prevalent, Epidemiology, Dupuytren Contracture, Dupuytren and Incidence. Subsequently, SID, MagIran, ScienceDirect, Embase, Scopus, PubMed and Web of Science databases and Google Scholar search engine were searched without a lower time limit and until June 2020. In order to analyse reliable studies, the stochastic effects model was used and the I2 index was applied to test the heterogeneity of the selected studies. Data analysis was performed within the Comprehensive Meta-Analysis Software version 2.0.

    RESULTS: By evaluating 85 studies (10 in Asia, 56 in Europe, 2 in Africa and 17 studies in America) with a total sample size of 6628506 individuals, the prevalence of Dupuytren disease in the world is found as 8.2% (95% CI 5.7-11.7%). The highest prevalence rate is reported in Africa with 17.2% (95% CI 13-22.3%). According to the subgroup analysis, in terms of underlying diseases, the highest prevalence was obtained in patients with type 1 diabetes with 34.1% (95% CI 25-44.6%). The results of meta-regression revealed a decreasing trend in the prevalence of Dupuytren disease by increasing the sample size and the research year (P < 0.05).

    CONCLUSION: The results of this study show that the prevalence of Dupuytren disease is particularly higher in alcoholic patients with diabetes. Therefore, the officials of the World Health Organization should design measures for the prevention and treatment of this disease.

    The attempt of this review article is to determine the impact of nuclear and mitochondrial damages on the propagation of cancer incidences. This review has advanced our understanding to altered genes and their relevant cancerous proteins. The progressive raising effects of free reactive oxygen species ROS and toxicogenic compounds contributed to significant mutation in nuclear and mitochondrial DNA where the incidence of gastric cancer is found to be linked with down regulation of some relevant genes and mutation in some important cellular proteins such as AMP-18 and CA-11. Thereby, the resulting changes in gene mutations induced the apparition of newly polymorphisms eventually leading to unusual cellular expression to mutant proteins. Reduction of these apoptotic growth factors and nuclear damages is increasingly accepted by cell reactivation effect, enhanced cellular signaling and DNA repairs. Acetylation, glycation, pegylation and phosphorylation are among the molecular techniques used in DNA repair for rectifying mutation incidences. In addition, the molecular labeling based fluorescent materials are currently used along with the bioconjugating of signal molecules in targeting disease translocation site, particularly cancers and tumors. These strategies would help in determining relevant compounds capable in overcoming problems of down regulating genes responsible for repair mechanisms. These issues of course need interplay of both proteomic and genomic studies often in combination of molecular engineering to cible the exact expressed gene relevant to these cancerous proteins.

    Parkinson's disease (PD) is the second most common neurodegenerative disorder. It is usually seen in those above 50 years old. Current medical treatments only provide symptomatic relief but cannot cure the disease. There are claims that PD can be cured by stem cell transplant. The present study is aimed to assess the clinical potency and safety of stem cell in treating PD. A total of eleven articles were included for analysis, with four randomised control trials (RCTs), five non-RCTs and 2 follow up studies. All the four non-RCTs showed improvement of Unified Parkinson's Disease Rating Scale with no adverse events. However, results from RCTs showed no significant differences in the rating score among the transplant group and the Sham surgery group. The secondary analysis of one study showed a significant improvement of the rating score in those patients aged 60 and younger. Transplant group also associated with an overall higher incidence of adverse events. In conclusion, the RCTs and non-RCTs produced opposite results. When the studies were performed as non-RCTs in small number of patients, they showed promising result in the patients. It could say that currently the use of stem cell/progenitor cells in treating PD need much research despite having the implanted stem cell to be able to survive and integrated. The survival of implanted dopamine neurons in the striatum, however, does not indicate a success in correcting PD symptoms. Further investigations will shed light on the application and mechanism of action of stem cells in treating PD.

    This study was designed to reveal the protective effects of dietary supplementation of curcumin against renal cell tumours and oxidative stress induced by renal carcinogen iron nitrilotriacetate (Fe-NTA) in ddY male mice. The results showed that mice treated with a renal carcinogen, Fe-NTA, a 35% renal cell tumour incidence was noticed, whereas renal cell tumour occurrence was elevated to 80% in Fe-NTA promoted and N-diethylnitrosamine (DEN)-initiated mice as compared with saline- treated mice. No incidence of tumours has been observed in DEN-initiated non-promoted mice. Diet complemented with 0.5% and 1.0% curcumin fed prior to, during and after treatment with Fe-NTA in DEN-initiated animals, tumour incidence was reduced dose-dependently to about 45% and 30% respectively. Immunohistochemical studies also revealed the increased formation of 4-hydroxy-2-nonenal (HNE)-modified protein adducts and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in kidney tissue of mice treated with an intraperitoneal injection of Fe-NTA (6.0 mg Fe/kg body weight.). Furthermore, Fe-NTA treatment of mice also resulted in significant elevation of malondialdehyde (MDA), serum urea, and creatinine and decreases renal glutathione. However, the changes in most of these parameters were attenuated dose-dependently by prophylactic treatment of animals with 0.5% and 1% curcumin diet, this may be due to its antioxidative impact of curcumin. These results suggest that intake of curcumin is beneficial for the prevention of renal cell tumours and oxidative stress damage mediated by renal carcinogen, Fe-NTA.

    Between January 1978 to December 1993, 130 cases of adrenal diseases were diagnosed and surgically treated at the National University of Malaysia. They were 58 cases (44.6%) of Conn's syndrome, 40 cases (30.7%) of Cushing's syndrome, 20 cases (15.3%) of phaeochromocytoma and 12 cases (9.2%) of adrenocortical carcinoma (ACC). The commonest cause of Conn's syndrome was an adenoma (96.5%) which affected the left gland four times more than the right gland. Cushing's syndrome was caused by adrenocortical adenoma (32.5%), diffuse bilateral adrenal hyperplasia (40.0%), pigmented macronodular hyperplasia (20.0%) and adrenal carcinoma (7.5%). Twenty-five percent of the phaeochromocytomas were extraadrenal in origin arising mainly from the abdominal sympathetic chain. More than 50% of ACCs were non-functioning tumours. Fifty percent of the patients with ACC had inoperable tumours. The prognosis was poor even with adjuvant chemoradiotherapy. The main surgical approach was the anterior transabdominal route. There was no operative mortality or morbidity in all operated cases.

    Acute (stab) peritoneal dialysis is commonly practised in Malaysia. This study is designed to improve the management of peritoneal dialysis (PD) in Hospital University Science Malaysia (HUSM). Consecutive peritoneal dialysis (PD) on adult inpatients from May 1992 to September 1992 were reviewed prospectively. There were 40 episodes of peritoneal dialysis on 27 patients during this period given at the rate of 2 PD per week. The mean age of patients were 53 +/- 15 years. Uraemia was the main indication for dialysis, while hyperkalaemia and pulmonary oedema were indications for urgent dialysis. Complications occurred in 14 episodes of dialysis (35%). The most common complication was bleeding in the peritoneal cavity while peritonitis was the second most common complication. Dialysis episodes complicated by peritonitis were done by less experienced performers compared to uncomplicated dialysis episodes. Overall mean time spent on each dialysis and time per cycle were longer than recommended (59 +/- 24 hours and 77 +/- 14 minutes). In conclusion, acute PD performed on patients admitted in Hospital University Malaysia was safe and had complication rates comparable to other established centres. However, improvements are possible through closer supervision of new doctors and tighter nursing precautions.

    The purpose of this study is to determine the relevance of the hygiene hypothesis; that is to determine if worm infestation has a protective role against the development of allergic rhinitis. A prospective case controlled study was conducted. Specific IgG levels to Toxocara were studied in 85 patients confirmed to have allergic rhinitis and were compared to levels in another 85 controls, with no form of allergy. The IgG assay was done using ELISA technique. There was a higher incidence of positive specific IgG to Toxocara in the controls as compared to allergic patients. The values were statistically significant [Chi square test (p=0.002)]. This negative association between worm infestation and allergic rhinitis suggests that a previous worm infestation could protect against the development of allergic rhinitis.

    The aim of study was to investigate the role of climate on the Malaria Incidence Rates (MIR) in some regions in of Yemen. For such purpose, the monthly (MIR) were calculated from the records of the hospitals' laboratories and centers of the Malaria Rollback centers in the main cities of the governorates Hudeidah, Taiz, Sana'a and Hadramout for the period 1989-1998. The readings of the climatic factors (CF) particularly the average monthly temperature (T), relative humidity (RH), volume of rain fall (RF) and wind speed (WS) for the same period of time were also collected from different weather and climatic information resources. Descriptive statistics, simple linear regression and multiple linear regression techniques were used to analyse the relationship between MIR and CF. The analysis shows highly significant relationship between MIR and the CF in these regions of Yemen (p-value 0.001).

    BACKGROUND: The incidence of acute compartment syndrome (ACS) following snakebite envenomation may be seriously overestimated in Taiwan. Snakebite-induced ACS is difficult to determine solely by clinical examination. Snakebite patients previously underwent surgical intervention based on speculation and general clinical examinations suggesting ACS presentations instead of direct intracompartmental pressure (IP) measurement prior to fasciotomy. Point-of-care ultrasound (POCUS) is a relatively widely available noninvasive tool. This study aimed to evaluate snakebite-envenomated patients for the presence of subcutaneous edema and diastolic retrograde arterial flow (DRAF).

    MATERIALS AND METHODS: Snakebite patients were prospectively recruited between 2017 and 2019. All patients were examined with POCUS to locate edema and directly visualize and measure the arterial flow in the compressed artery. The presence of DRAF in the compressed artery is suggestive of ACS development because when compartment space restriction occurs, increased retrograde arterial flow is observed in the artery.

    RESULTS: Twenty-seven snakebite patients were analyzed. Seventeen patients (63%) were bitten by Crotalinae snakes, seven (26%) by Colubridae, one (4%) by Elapidae, and two (7%) had unidentified snakebites. All Crotalinae bit patients received antivenom, had subcutaneous edema and lacked DRAF in a POCUS examination series.

    DISCUSSION: POCUS facilitates clinical decisions for snakebite envenomation. We also highlighted that the anatomic site of the snakebite is an important factor affecting the prognosis of the wounds. There were limitations of this study, including a small number of patients and no comparison with the generally accepted invasive evaluation for ACS.

    CONCLUSIONS: We are unable to state that POCUS is a valid surrogate measurement of ACS from this study but see this as a starting point to develop further research in this area. Further study will be needed to better define the utility of POCUS in patients envenomated by snakes throughout the world.

    Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves worn by the surgical team were assessed after the surgery using the water-loading test. A total of 1452 gloves were tested, and the rate of perforation was 3.58%. Most of these perforations (61.5%) were unnoticed. The main surgeons had the most perforations (76.9%), followed by first assistants (13.5%) and second assistants (9.6%). Most perforations occurred at the non-dominant hand. The commonest site of perforation was the index finger followed by the thumb. Shearing force with instruments accounted for 45% of the noticed perforations. Majority of these occurred during nailing procedures (33%) and internal fixation without the use of wires (19%). Our rate of glove perforation is similar to other series. Most of them went unnoticed and were mainly due to shearing injuries rather than perforation by sharps. Therefore, there is an increased risk of contamination and break in asepsis during surgery.

    Low Grade Papillary Nasopharyngeal Adenocarcinoma (LGPAC) is a very rare tumour of mucosal origin compared to a higher incidence of well differentiated keratinized/non-keratinized nasopharyngeal carcinoma. It is an epithelial tumour with glandular differentiation. Its papillary figure seen histologically, is also seen in metastatic papillary thyroid carcinoma. This has caused a significant challenge to the Pathologist to differentiate primary papillary nasopharyngeal adenocarcinoma and metastatic tumour. Thyroid Transcription Factor-1 (TTF-1) is also expressed in subsets of papillary nasopharyngeal adenocarcinoma, which is valuable as a diagnostic tool. LGPAC is a benign-like malignant neoplasm. An early diagnosis with a complete tumour removal via conventional excision or endoscopic approach has offered a good prognosis with low risk of recurrence.

    A high frequency of bronchopulmonary infections complicating rheumatoid arthritis has been described in reports of case series. This study was undertaken to confirm and compare these finding in patients with RA and control. 117 patients with RA and 103 patients with OA/soft tissue rheumatism as controls. Study subjects were studied using their medical records available from hospitals' casenotes and GP data base. Details of all documented bronchopulmonary infections for the preceding year including lower and upper respiratory tract infections were recorded. Details of hospital admissions due to bronchopulmonary infection, antibiotic usage and functional capacity were also recorded. Mean age for RA was 56 and 59 for control. There were 34 males and 83 females in RA group, however, 14 males and 55 females in control group. There were at least 1 episodes of BPI in 66.7% (p<0.05) patients with RA and 48.5% in control. 69.2% (p<0.05) of subgroup patients with RA were noted to have poorer functional capacity compared to 50% in control. More RA patients with BPI (15%) (p<0.05) were admitted to hospital compared to control (3.8%). Significance findings were noted in terms of prevalence of BPI in RA patients compared to controls as well as patients with RA have severe course of BPI warranting hospitalization. RA patients with poorer functional capacity also noted to have high incidence of BPI.

    Accidental needle-stick injuries (NSIs) are a hazard for health-care workers and general public health. Orthopaedic surgeons may be more prone to NSIs due to the prevalence of bone spikes in the operative field and the use of sharp orthopaedic instruments such as drills, saws and wires. A hospital-based cross sectional study was conducted in the orthopedic wards of Melaka General Hospital. The prevalence of NSIs was 32 (20.9%) and majority of it occurred during assisting in operation theatre 13(37.4%). Among them six (18.8%) were specialist, 12(37.5%) medical officer, 10 (31.2%) house officer and four staff nurses (12.5%). Among the respondents 142 (92.8%) had been immunized against Hepatitis B and 148 (96.7%) participants had knowledge regarding universal precaution. The incidence of NSI among health care workers at orthopaedics ward was not any higher in comparison with the similar studies and it was found out that the prevalence was more in junior doctors compared with specialist and staff nurses and it was statistically significant.

    A community study on the age and sex related prevalence, intensity infection and frequency distribution of Ascaris, Trichuris and hookworm was carried out in 205 Orang Asli (Aborigines) children (95 boys, 110 girls) aged 1-13 years. The overall prevalence of Ascaris, Trichuris and hookworm was 62.9%, 91.7% and 28.8%, respectively. Almost two-thirds of the children were infected with moderate and severe intensity infection of Trichuris, 46.3% had moderate to severe intensity infection of Ascaris. However only 1.5% had moderate intensity of hookworm infection. The prevalence and mean intensity infection (measured by eggs per g) of Ascaris was age-dependent; lower in age group 1-4 years reached peak and stable at age group 5 years and above. The prevalence of Trichuris was high in all age groups and it fluctuated with age; the mean intensity of infection of Trichuris (measured by eggs per g) was age-dependent. Hookworm infection also rose with age and reached peak at 5-6 years, following that the prevalence declined. The frequency distributions of Ascaris, and hookworm were overdispersed. A strong positive correlation (p < 0.001) were observed between Ascaris and Trichuris and between hookworm and Trichuris. A positive correlation (p < 0.01) were also observed between Ascaris and hookworm.

    Oesophageal strictures often occur following esophagectomy which is performed for cases of oesophageal cancer. These patients require repeated dilation procedures. The aim of this study is to investigate the effects of dietary regimens, which are changed because of stenosis, caused by Helicobacter pylori (H. pylori). In this retrospective study, 28 patients who had operation for oesophageal cancer and underwent dilation due to development of stricture were studied. 30 female and 30 male patients who were admitted to the Gastroenterology Clinic with complaints of dyspepsia and did not receive treatment for the eradication of H. pylori were randomly selected and included in this study as a control group. Patients' histopathological records on the hemogram, biochemistry, and endoscopic biopsy were analysed. There were 26 H. pylori (+) cases (92.8 %) in the stenosis group consisting of 28 patients, and 37 H. pylori (+) cases (61.6%) in the control group consisting of 60 patients. These results were found to be statistically significant (P=0.003). The albumin level in the stenosis group was reported to be statistically low (P=0.002). The incidence of H. pylori was found to be significantly higher in patients with stenosis. We ascribed this outcome due to changes in dietary regimens. Our findings showed that the dietary regimens of all patients who underwent esophagectomy should be regulated during the postoperative period considering H. pylori. The relationship between H. pylori and stenosis was significant, there is a need for further research with a larger sample size to enrich the findings.

    Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV-related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV-related morbidity and mortality.
