Migrating foreign body into the common carotid artery and internal jugular vein – A rare case

Ingested foreign bodies are a fairly common otorhinolaryngological emergencies encountered in Malaysia. The vast majority of these foreign bodies are fish bones which most commonly are impacted at the level of the cricopharynx. Rarely, however, a foreign body may migrate extraluminally and may even extrude subcutaneously. We report a rare occurrence where a fish bone not only migrated extraluminally, it was found to have migrated into the common carotid artery and the internal jugular vein and required surgical removal.     

Quality of life in Palestinian patients with end-stage renal disease receiving treatment by haemodialysis: a cross-sectional study

Background

Haemodialysis is a life-saving but burdensome therapy for patients with end-stage renal disease, which can substantially impair health-related quality of life (HRQOL) and outcomes. The aim of this study was to determine the patterns of HRQOL and to identify the risk factors for reduced HRQOL in Palestinian patients receiving treatment by haemodialysis.

A bibliometric analysis of toxicology research productivity in Middle Eastern Arab countries during a 10-year period (2003–2012)

Background

The key to universal coverage in tuberculosis (TB) management lies in community participation and empowerment of the population. Social infrastructure development generates social capital and addresses the crucial social determinants of TB, thereby improving program performance. Recently, there has been renewed interest in the concept of social infrastructure development for TB control in developing countries. This study aims to revive this concept and highlight the fact that documentation on ways to operationalize urban TB control is required from a holistic development perspective. Further, it explains how development of social infrastructure impacts health and development outcomes, especially with respect to TB in urban settings.

Methods

A wide range of published Government records pertaining to social development parameters and TB program surveillance, between 2001 and 2011 in Delhi, were studied. Social infrastructure development parameters like human development index along with other indicators reflecting patient profile and habitation in urban settings were selected as social determinants of TB. These include adult literacy rates, per capita income, net migration rates, percentage growth in slum population, and percentage of urban population living in one-room dwelling units. The impact of the Revised National Tuberculosis Control Program on TB incidence was assessed as an annual decline in new TB cases notified under the program. Univariate linear regression was employed to examine the interrelationship between social development parameters and TB program outcomes.

Results

The decade saw a significant growth in most of the social development parameters in the State. TB program performance showed 46% increment in lives saved among all types of TB cases per 100,000 population. The 7% reduction in new TB case notifications from the year 2001 to 2011, translates to a logarithmic decline of 5.4 new TB cases per 100,000 population. Except per capita income, literacy, and net migration rates, other social determinants showed significant correlation with decline in new TB cases per 100,000 population.

Conclusions

Social infrastructure development leads to social capital generation which engenders positive growth in TB program outcomes. Strategies which promote social infrastructure development should find adequate weightage in the overall policy framework for urban TB control in developing countries.     

Assessment of health-related quality of life among hypertensive patients: a cross-sectional study from Palestine

Aim

The ability to identify indicators of poor health-related quality of life (HRQoL) is crucial for both improving clinical care and determining targets of intervention for the prevention and treatment of disease. The main objectives of this study were to assess the HRQoL profile of the hypertensive population from Palestine, and to determine the socio-demographic and clinical characteristics associated with poor HRQoL.

Subject and methods

A cross sectional study was conducted, adopting the EuroQoL-5 Dimensions scale (EQ-5D-5 L) for the assessment of HRQoL. Hypertensive patients attending outpatients’ clinics at Al-Makhfyah primary health care clinic and from Alwatani Hospital, Nablus, Palestine were approached for study.

Results

Four hundred and ten hypertensive patients were enrolled in the study. Of these, 213 patients (52 %) were female. The average age of the study population was 58.38?±?10.65 years. HRQoL was good, with a mean EQ-5D-5 L index value and EQ visual analogue scale (EQ-VAS) score of 0.80?±?0.16 and 74.1?±?15.6 respectively. There was a significant positive correlation (r?=?0.56; p?<?0.001) between the EQ-5D-5 L index values and the reported EQ-VAS scores. A significant difference in EQ-5D-5 L index values was found among participants when grouped according to age, occupation, marital status, income, educational level, duration of disease, total number of chronic diseases, and total number of medications (Kruskal–Wallis test; p-value?<?0.05), as well as gender and therapy type (Mann–Whitney test, p-value?<?0.05).

Conclusions

This study highlighted that specific socio-demographic and disease-related characteristics of hypertensive patients as well as treatment factors were strongly associated with HRQoL. The study findings could be helpful in clinical practice, mainly in the early treatment of hypertensive patients, at a point where improving HRQoL is still possible.     

Hepatoprotective Properties of Aqueous Leaf Extract of Persea Americana,Mill (Lauraceae) ‘Avocado’ Against CCL4-Induced Damage in Rats

Background

Natural products from plants have received considerable attention in recent years due to their diverse pharmacological properties, including antioxidants and hepatoprotective activities. The protective effects of aqueous extract of Persea americana (AEPA) against carbon tetrachloride (CCl₄)-induced hepatotoxicity in male albino rats was investigated.

Materials and Methods

Liver damage was induced in rats by administering a 1:1 (v/v) mixture of CCl₄ and olive oil [3 ml/kg, subcutaneously (sc)] after pre-treatment for 7 days with AEPA. Hepatoprotective effects of AEPA was evaluated by estimating the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and levels of total bilirubin (TBL). The effects of AEPA on biomarkers of oxidative damage (lipid peroxidation) and antioxidant enzymes namely, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione S-transferase (GST) were measured in liver post mitochondrial fraction.

Results

AEPA and Reducdyn® showed significant (p<0.05) hepatoprotective activity by decreasing the activities of ALT, AST, ALP and reducing the levels of TBL. The activities of antioxidant enzymes, levels of malondialdehyde and protein carbonyls were also decreased dose-dependently in the AEPA-treated rats. Pre-treatment with AEPA also decreased the serum levels of glutathione significantly.

Conclusion

These data revealed that AEPA possesses significant hepatoprotective effects against CCl₄-induced toxicity attributable to its constituent phytochemicals. The mechanism of hepatoprotection seems to be through modulation of antioxidant enzyme system.     

Assessment of Nipah virus transmission among pork sellers in Seremban, Malaysia

Between September 1998 and May 1999, 265 cases of encephalitis were reported from among those involved in pig rearing. A few cases were also reported among abattoir workers. This raised questions of the risk of transmission among those who handled raw pork. A serosurvey was conducted among pork sellers in Seremban town, which is about 20 km from one of the pig rearing areas which had reported cases of encephalitis. It was found that out of the 28 pork sellers tested, only one tested positive for Nipah virus antibodies and that this pork seller also worked in an abattoir in the same district, removing the urinary bladders from slaughtered pigs. Based on these findings, it was concluded that the risk of transmission of the virus from handling raw pork appeared to be low.
