The aim of this study was to appraise the prescription writing skills of preclinical undergraduate students of College of Medical Sciences, Bharatpur. This prospective study was conducted over each of 150 of 1st year and 2nd year medical students in the months of May and June 2010 under the guidelines of World Health Organization (WHO). Prescriber’s identity, patient’s identity, the diagnosis, the symbol-Rx and prescriber’s signature were available on 90% and above of the prescriptions written by both year students. A large number of them also mentioned the prescriber’s address and the date of prescription. The information, instructions, warnings and patient’s address were the most deficient aspects among prescriber’s related components and the strength, the quantity to be dispensed and the direction for the use of drugs were the deficient aspects of drug related components. Comparatively more deficiencies were noted for drug related components. As an overall, the performance of 2nd year medical students was better than that of the 1st year. This study reveals that the prescription writing skills of preclinical medical students were sub-optimal and need emphasis for some elements during their clinical years and internship. However, there is a good scope of learning this skill also in the existing method of pharmacology teaching.

An unusual histological variant of collagenoma is described. A 36-year-old woman presented with a lump in the left hypothenar eminence. Histological examination revealed a well-delineated lesion composed of paucicellular collagen fibres arranged in concentric lamellations giving rise to an onion skin appearance. The overlying epidermis was thin and the lateral borders were demarcated by an epidermal collarette. Inflammation and xanthoma cells were absent and occasional capillaries were present. The lesion was positive for collagen stains, reticulin and CD34. This lesion represents an uncommon histological form of collagenoma or fibroma. It can be distinguished from histological look-alikes on the basis of the characteristic morphology and immunophenotype.

Infectious disease epidemics may overshadow and exacerbate existing challenges in diagnosing lymphoma. We describe pragmatic strategies we have implemented to overcome diagnostic obstacles caused by the local tuberculosis (TB) and HIV epidemics in South Africa, which may serve as a guide to minimize diagnostic delay during the COVID-19 pandemic. We report on the diagnostic utility of a rapid-access lymph node core-biopsy clinic, where lymph node biopsies are taken from outpatients at their first visit. Analysis of tissue biopsies (n ¼ 110) revealed the three most common conditions diagnosed were TB adenitis (34%), lymphoma (29%), and disseminated malignancy (20%). A first-attempt core-biopsy was able to diagnose lymphoma in 27/ 32 (84%) of cases. Compared with a historical cohort, the diagnostic interval (time from first health visit to diagnostic biopsy) for patients with lymphoma was significantly shorter, 13.5 vs 48 days (p ¼ 0.002).

Plasmablastic lymphoma (PBL) is a highly aggressive B cell non-Hodgkin lymphoma frequently associated with immunosuppression, particularly human immunodeficiency virus (HIV) infection. Although PBL is rare globally, South Africa has a high burden of HIV infection leading to a higher incidence of PBL in the region. Laboratory features in PBL may overlap with plasmablastic myeloma and other large B cell lymphomas with plasmablastic or immunoblastic morphology leading to diagnostic dilemmas. There are, however, pertinent distinguishing laboratory features in PBL such as a plasma cell immunophenotype with MYC overexpression, expression of Epstein-Barr virus-encoded small RNAs and lack of anaplastic lymphoma kinase (ALK) expression. This review aims to provide a summary of current knowledge in PBL, focusing on the epidemiology, pathophysiology, laboratory diagnosis and clinical management.

A 46-year-old man presented with nonproductive cough and lower limb swelling. Chest radiograph showed a left lower lobe lung mass and multiple subpleural nodules. Other investigations revealed that he had nephrotic syndrome. Core biopsies of the left lower lobe lung mass showed features of inflammatory pseudotumor with endarteritis obliterans and a lymphoplasmacytic infiltrate. Immunohistochemical stain for Treponema pallidum was positive. Resolution of the lung mass and nephrotic syndrome was achieved after treatment with intramuscular benzathine benzylpenicillin. The differential diagnosis of pulmonary inflammatory pseudotumor, manifestations of pulmonary syphilis, and a literature review of secondary syphilis of the lung are discussed.
