Pathology, East Africa

Background: This study assessed the safety of the new World Health Organization (WHO) recommendation of adding a single low-dose of primaquine (PQ) to standard artemisinin-based combination therapy (ACT), regardless of individual glucose-6-phosphate dehydrogenase (G6PD) status, for treatment of acute uncomplicated Plasmodium falciparum malaria in Tanzania.

Methods: Men and non-pregnant, non-lactating women aged ≥1 year with uncomplicated P. falciparum malaria were enrolled and randomized to either standard artemether-lumefantrine (AL) regimen alone or with a 0.25 mg/kg single-dose of PQ. PQ was administered concomitantly with the first AL dose. All drug doses were supervised. Safety was evaluated between days 0 and 28. …

Department of Pathology and Laboratory Medicine

Background: Central neurocytomas are rare neuronal neoplasms with a favorable prognosis. They are typically located in the lateral ventricles of the brain and mostly histologically correspond to WHO grade II with a Mib 1 labelling index of 2 % and are designated as "atypical neurocytomas.AIM: The aim of our study was to describe the common as well as unusual morphologic features and the role of various immunohistochemical stains in the diagnosis of these rare tumors.MATERIALS AND Methods: We retrieved and reviewed 35 cases diagnosed between 2001 and 2015.Results: Sixty percent of patients were males, and the mean age was 26 …

Sporadic Early Onset Colorectal Cancer In Pakistan: A Case- Control Analysis Of Microsatellite Instability, Sabeehuddin Siddique, Kanwal Tariq, Sobia Rafiq, Ahmed Raheem, Rashida Ahmed, Munira Shabbir-Moosajee, Kulsoom Ghias

Department of Pathology and Laboratory Medicine

Background: Early onset sporadic colorectal cancer (CRC) is a biologically and clinically distinct entity hypothesized to exhibit differences in histological features and microsatellite instability (MSI) as compared to typical onset CRC. This study compared the MSI status, mismatch repair enzyme deficiency and clinicopathological features of early onset (aged ≤45 years) with controls (>45 years).
Materials and Methods: A total of 30 cases and 30 controls were analyzed for MSI status using the Bethesda marker panel. Using antibodies against hMLH1, hMSH2 and hMSH6, mismatch repair protein expression was assessed by immunohistochemistry. Molecular characteristics were correlated with clinicopathological features.
Results: …

The Experience Of Being Unsheltered In Atlanta, Ikeranda Smith

Walden Dissertations and Doctoral Studies

In the United States, it is estimated that millions of adults are homeless. Some individuals choose not to use homeless shelters or are ineligible for their use. Researchers have indicated that many unsheltered homeless are men over the age of 45 years. The purpose of this phenomenological study was to examine the experiences with social services providers among unsheltered men. Understanding the social networks of unsheltered homeless and the use of spirituality or faith as a resource for coping was also examined, as a significant gap exists in the research on unsheltered homeless. Face-to-face, in-depth interviews were conducted with 8 …

Errors In Surgical Pathology Reports: A Study From A Major Center In Pakistan, Zubair Ahmad, Romana Idrees, Nasir Uddin, Arsalan Ahmed, Saira Fatima

Department of Pathology and Laboratory Medicine

Background:
Errors in surgical pathology diagnosis can have serious consequences for the patient. Since the final product of a surgical pathology lab is the report, errors can be picked by reviewing reports of cases.AIM: To determine the frequency and types of error in surgical pathology reports of cases signed out in 2014 in a laboratory in Karachi, Pakistan.
Material and Methods:
All surgical pathology reports in which changes were made in the original report after sign out and an amended report was issued were included. Errors included: (1) misinterpretations; (2) missing critical information; (3) erroneous critical information; (4) misidentification; and …

Department of Pathology and Laboratory Medicine

Background: The “Philadelphia Negative Classic Myeloproliferative Neoplasms” include polycythaemia vera (PV), essential thrombocythaemia (ET) andidiopathic myelofibrosis (IMF). These three disorders share several clinical and laboratory features including JAK2 V617F mutation. Our objectives were to determine the clinicoat hological profile and outcomes of Pakistani patients with polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) in order to have an insight regarding behaviour of these conditions.
Methods: A retrospective analysis of all the cases of PV, ET and IMF diagnosed at our institute from January 1995 to December 2013 was performed.Age, gender, clinical presentation, laboratory investigations, treatment provided and …

Agreement Of Direct Antifungal Susceptibility Testing From Positive Blood Culture Bottles With The Conventional Method For Candida Species, Kauser Jabeen, Haresh Kumar, Joveria Farooqi, Raunaq Mehboob, Mary E. Brandt, Afia Zafar

Department of Pathology and Laboratory Medicine

Early availability of antifungal susceptibilities can ensure timely institution of targeted therapy in candidemia, which can improve patient outcomes. This study prospectively determines the agreement between the results of direct testing of antifungal susceptibilities from blood culture bottles by disk diffusion and Etest and the results of standardized susceptibility testing methods; direct testing would allow susceptibility results to be available 1 to 2 days earlier. A total of 104 blood cultures with different Candida species (28% C. albicans, 27% C. parapsilosis, 26% C. tropicalis, etc.) were evaluated between January 2012 and May 2013 for agreement of fluconazole, voriconazole, and amphotericin …
