Blastocystis Hominis And Dientamoeba Fragilis In Patients Fulfilling Irritable Bowel Syndrome Criteria., Javed Yakoob, Wasim Jafri, Mohammad Asim Beg,, Z Abbas, Shagufta Naz,, Muhammad Islam, Rustam Khan

Section of Gastroenterology

Studies have suggested a possible role for Blastocystis hominis and Dientamoeba fragilis in the etiology of irritable bowel syndrome (IBS). We studied the prevalence of B. hominis and D. fragilis in patients with IBS-diarrhea (IBS-D). Three hundred and thirty patients were enrolled, 171 (52%) with IBS-D and 159 (48%) were controls, respectively. Stool microscopy, culture, and polymerase chain reaction (PCR) for B. hominis and D. fragilis were done. B. hominis was positive by stool microscopy in 49% (83/171) of IBS compared to 24% (27/159) in control (p < 0.001). B. hominis culture was positive in 53% (90/171) in IBS compared to 16% (25/159) in control (p < 0.001). B. hominis PCR was positive in 44% (75/171) in IBS compared to 21% (33/159) in control (p < 0.001). D. fragilis microscopy was positive in 3.5% (6/171) in IBS-D compared to 0.6% (1/159) in control (p = 0.123). D. fragilis culture was positive in 4% (7/171) in IBS compared to 1.3% (2/159) in control (p = 0.176). D. fragilis PCR was positive in 4% (6/171) in IBS-D compared to 0% (0/159) in control (p = 0.030). B. hominis is common, while D. fragilis was less prevalent in our patients with IBS-D. B. hominis and D. fragilis culture had a better yield compared to stool microscopy and PCR.

Perceived Stigma Among Patients Receiving Antiretroviral Treatment: A Prospective Randomised Trial Comparing An M-Dot Strategy With Standard-Of-Care In Kenya, Susan Kaai, Sandra Bullock, Avina Sarna, Matthew Chersich, Stanley Luchters, Scott Geibel, Kishorchandra Mandaliya, Marleen Temmerman, Naomi Rutenberg

Population Health, East Africa

HIV and AIDS remain highly stigmatised. Modified directly observed therapy (m-DOT) supports antiretroviral treatment (ART) adherence but little is known about its association with perceived stigma in resource-constrained settings. In 2003, 234 HIV-infected adults enrolled in a two-arm randomised trial comparing a health centre-based m-DOT strategy with standard self-administration of ART. Data on perceived stigma were collected using Berger's HIV stigma scale prior to starting ART and after 12 months. This was a secondary analysis to examine whether perceived stigma was related to treatment delivery. Perceived stigma scores declined after 12 months of treatment from a mean of 44.9 (sd=7.6) …

Immunophenotypic Profile Of Acute Leukemias At Agakhan University Hospital, Nairobi, Beatrice M. Kabera

Master of Medicine in Clinical Pathology

Background: Reliable distinction between AML and ALL is important for the selection of appropriate therapy. The final diagnosis of acute leukemia should be based on clinico-pathological, morphological, cytochemical and molecular cytogenetics data, together with immunophenotypic information. Flow cytometry has become the preferred method for the lineage assignment and maturational analysis of malignant cells in acute leukemias. Immunophenotyping has also allowed the detection of aberrant antigen co expression and the analysis of heterogeneity and clonality of malignant cells in acute leukemias. It is insufficient to merely make a diagnosis of acute leukemia, or even AML or ALL. Further classification is essential …

Detection Of Extended Spectrum Beta Lactamases Genotypes And Their Association With Cephalosporin Susceptibility In Community Acquired Enterobacteriaceae Infections, Daniel W. Maina

Master of Medicine in Clinical Pathology

Background: Infections caused by Extended Spectrum Beta-Lactamases (ESBLs) producing enterobacteriaceae have become a global problem. Initially confined to the hospital set-up, they are increasingly being reported in the community. These infections are often resistant to a wide variety of B- lactams including extended spectrum cephalosporins, with clinical and epidemiological implications for healthcare systems and necessitate surveillance measures based on local data. Local information on the genotypes of ESBLs and their association with cephalosporin resistance in community acquired ESBL-producing Enterobacteriaceae isolates is scanty, hence the need for this study. Aim: To detect ESBLs genotypes and correlate these with susceptibility to cephalosporins …

Craniocerebral Aspergillosis: A Review Of Advances In Diagnosis And Management, Muhammad Shahzad Shamim, Ather Enam, Rushna Ali, Saleha Anwar

Section of Neurosurgery

Craniocerebral aspergillosis is a rare but dangerous central nervous system infection. The infection has a spectrum of presenting features, mostly affecting immunocompromised individuals. The incidence appears to be on the rise that has been especially observed in the immunocompetent population. A high index of suspicion, a comprehensive understanding of the infectious process and advanced laboratory and radiological diagnostic techniques, allow early diagnosis. Surgery, followed by systemic antifungal medications, remains the cornerstone of management. Early administration of empirical anti-fungal agents along with immunomodulators may further improve prognosis. Immunocompetent patients tend to have better outcomes as compared to those who are immunocompromised. …

Antispasmodic, Bronchodilator And Blood Pressure Lowering Properties Of Hypericum Oblongifolium - Possible Mechanism Of Action, Arif-Ullah Khan, Munasib Khan, Fazal Subhan, Anwar Gilani

Department of Biological & Biomedical Sciences

The crude extract of Hypericum oblongifolium (Ho.Cr), which tested positive for flavonoids, saponins and tannins caused concentration-dependent (0.1-1.0 mg/mL) relaxation of spontaneous and high K(+) (80 mM)-induced contractions in isolated rabbit jejunum preparations, suggesting a Ca(++) antagonistic effect, which was confirmed when pretreatment of the tissue with Ho.Cr produced a rightward shift in the Ca(++) concentration-response curves, like that caused by verapamil. Ho.Cr relaxed carbachol (1 mu M) and high K(+)-induced contractions in guinea pig tracheal preparations. It caused a dose-dependent (3-100 mg/kg) fall in arterial blood pressure of rats under anesthesia. In isolated guinea pig atria, Ho.Cr caused inhibition …
