Prevalence and molecular detection of contagious bovine pleuropneumonia in large ruminants in Punjab, Pakistan

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides. It is characterized by anorexia, fever, dyspnea, polypnea, cough, and nasal discharges. Gross lesions in the lung such as marbling, sequestra, thickening of interlobular septa, and consolidation are evident. Serological tests including complement fixation test and competitive enzyme-linked immunosorbent assay and molecular tests such as polymerase chain reactions are used for diagnostic purposes. In this study, lung samples of suspected large ruminants (cattle n=560, buffalo n=293) were collected from abattoirs of three districts of Punjab namely Lahore, Kasur and Jhang. PCR was performed with specific primers, targeting the 16S ribosomal RNA gene to detect the positive cases. The results indicated that 49 samples (8.75%) of cattle were positive, with maximum prevalence was observed in Jhang with 16 positive samples (10.06%), but CBPP was not detected in any buffalo sample. High prevalence of disease was seen in cattle of more than seven years of age, in female cattle, and in cross-bred cattle. Age and gender were found significantly associated (P<0.05) with the prevalence of the disease. Gene sequencing of identified 5 isolates of Mycoplasma mycoides subsp. mycoides had more than 99% similarities with the strains isolated from China, Italy, Australia and Tanzania and were categorized into a monophyletic group but strain isolated from Portugal had more than 55% variable regions, hence clustered separately. This study confirms the presence of contagious bovine pleuropneumonia in the country which can be a threat to the livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

Estimation of the Direct Cost of Poliomyelitis Rehabilitation Treatment to Pakistani Patients: A 53-Year Retrospective Study

BACKGROUND

Pakistan is one of the last few countries in which poliomyelitis is endemic. Evidence indicates that out-of-pocket expenditures are a barrier to polio rehabilitation treatment, yet there are no reported figures related to the financial burden of this disease on patients in a recently polio-endemic country.

OBJECTIVE

This study investigated direct costs attributed to rehabilitation treatment of poliomyelitis among Pakistani patients and reported its duration along with the socioeconomic status of poliomyelitis survivors.

CONCLUSION

The cost of poliomyelitis rehabilitation in Pakistan is high; it has an economic effect on the lives of patients and their families. Despite good education, polio survivors in Pakistan appear to have low socioeconomic status, lower chances of employment and marriage, as well as fewer children. Further research is recommended to explore the burden of disease on society, i.e., indirect costs and suffering.

Awareness, knowledge and attitude towards breast cancer, breast screening and early detection techniques among women in Pakistan

OBJECTIVE

To document the knowledge and attitudes of women towards breast cancer, breast screening and early detection techniques.

METHODS

This cross-sectional survey was conducted from December 2015 to May 2016 in Karachi and Islamabad, Pakistan, and comprised women aged above 18 years. The survey used breast cancer inventory as a research instrument after piloting and validation. SPSS 20 was used for data analysis.

RESULTS

Of the 1,304 respondents, 948(72.7%) were single, 1,082(83%) belonged to the 18-30 age group, 800(61.3%) had Urdu-speaking ethnicity and 794(60.9%) were educated. The prevalence of breast cancer in family was 226(17.33%). Besides, 446(34.2%) had low knowledge regarding the subject, 646(49.5%) appeared welcoming to the idea of breast screening, 1,008(77.3%) indicated their discomfort in discussing the topic, whereas 1,080(82.8%)preferred a female physician.

CONCLUSIONS

There was a dearth of knowledge regarding breast cancer among the participants..

Evaluation of antiviral activity of plant extracts against foot and mouth disease virus in vitro

The aim of this study was to evaluate antiviral activity of chloroformic leaves extracts of three plants: Azadirachta indica, Moringa oleifera and Morus alba against Foot and Mouth disease virus using MTT assay (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide). Antiviral and cytotoxic activity of each extract was evaluated as cell survival percentage and results were expressed as Means ± S.D. The concentrations which resulted in cell survival percentages of greater than 50% are considered to be effective antiviral concentrations. From the tested plant extracts, Moringa oleifera showed potent antiviral activity (p<0.05) while Azadirachta indica showed significant antiviral activity in the range of 1-50μ/ml & 12-100μ/ml respectively. In contrast no antiviral activity was observed by Morus alba as all the tested concentration resulted in significant reduction (p<0.05) in cell survival percentage.

Massive retroperitoneal pseudotumour in a patient with type 3 von Willebrand disease

Formation of destructive haemorrhagic pseudocysts or pseudotumours thought to arise from unresolved, encapsulated haematomas is a well-recognized, rare complication of severe haemophilia A or B, and has been reported in a single patient with von Willebrand disease (vWD). We report a 41-year-old patient with type 3 vWD who underwent incomplete resection of a large retroperitoneal pseudocyst in 1995 and presented with a recurrent, extensive right abdominal and flank mass and signs and symptoms of large bowel obstruction. He required emergency partial colectomy for bowel ischaemia and removal of his right kidney, which was hydronephrotic due to prolonged ureteral obstruction by the pseudocyst. Following repeat partial resection of the pseudotumour, he developed persistent bleeding into the operative site despite aggressive administration of von Willebrand factor (vWF)-rich factor VIII concentrates, resulting in retroperitoneal haematomas and abscesses, which resolved after 13 months of percutaneous drainage, extended supplementation of vWF and antibiotic therapy.
