Tubercular lymphadenitis (TBLA) contributes to 30-40% of extrapulmonary TB cases in the immunocompetent individuals and 40-50% in people with HIV. Current diagnostic methods for TBLA like Gene-Xpert or PCR are costly and conventional methods like fine needle aspiration cytology, histopathology lack sensitivity and specificity. Culture which is considered as gold standard require high turnaround time. Loop mediated isothermal amplification (LAMP) assay has been developed as a novel technique for nucleic acid amplification and has shown promising results in the diagnosis of pulmonary tuberculosis...

Background/aim: Mediastinal lymph nodes are the second most commonly affected lymph nodes in tuberculous lymphadenitis. It is often difficult to diagnose tuberculosis in patients with lymphadenopathy without parenchymal lesions. The aim of this study was to describe the diagnostic utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with isolated mediastinal tuberculous lymphadenitis (MTLA). Materials and methods: This study included 527 patients who had undergone EBUS-TBNA between December 2012 and December 2014...

Alkhumra hemorrhagic fever virus (AHFV) is an emerging novel flavivirus that was discovered in Saudi Arabia in 1995. The virus has since caused several outbreaks in the country that resulted in case fatality rates ranging from 1% to 25%. Meager information has been published on the ultrastructural features of the virus on cells under in vitro or in vivo conditions. The present electron microscopic study examined and compared the intracellular growth of the AHFV on the LLC-MK2 cells and brain cells of new born Wistar rats, inoculated intracerebrally...

Amyloidosis is a rare condition resulting from extracellular deposition of amyloid, a fibrillary material derived from various precursor proteins. Involvement of the pleura by amyloidosis is a rare but serious complication. Pleural amyloidosis is primarily diagnosed by identifying amyloid deposition by histology on pleural biopsy specimens. Hereby, we report a case of systemic amyloidosis where we were able to identify amyloid in a pleural effusion specimen sent for cytopathology evaluation. A 59-year-old male with newly diagnosed multiple myeloma and systemic amyloidosis underwent therapeutic thoracentesis...

Thyroid nodules affect nearly two-thirds of the world population. Fine-needle biopsy with cytologic evaluation remains the diagnostic test of choice to distinguish benign from malignant thyroid nodules yet fails to discriminate as benign or malignant in up to one-third of cases. This review discusses the limitation of current cytopathologic evaluation, the development of thyroid molecular testing, and the strengths and limitations of commercially available tests. Initial cytomolecular testing sought to identify specific gene mutations associated with thyroid cancer...

REVIEW
Yin P Hung, Justine A Barletta
The term non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was recently introduced to replace a subset of follicular variant of papillary thyroid carcinoma (FVPTC). The goal of this change was to promote more conservative management of these tumours and spare patients the psychological burden of a cancer diagnosis. The histological diagnosis of NIFTP is stringent: the tumour needs to demonstrate encapsulation or circumscription, a purely follicular architecture and the presence of nuclear features of papillary thyroid carcinoma, while lacking capsular and vascular invasion, a significant component of solid growth and high-grade features (increased mitotic activity and necrosis)...

BACKGROUND: Exfoliative cytology is an easy, economical, noninvasive, and feasible method for early detection and screening program of any premalignant or malignant lesion. In case of routine cytological procedure, classical Papanicolaou (PAP) stain is widely used while Romanowsky stains are sparingly used. Leishman-Giemsa (LG) cocktail, being a easier, cost effective staining technique, has not been used in exfoliative cytology. Therefore, this pilot study was carried out to compare and contrast the role of LG stain in routine cytological procedure which is very cost-effective, less time-consuming and requires less infrastructural support...

Molecular pathological analysis has an expanding role in patient diagnosis and management. The performance of these techniques relies on excellent laboratory procedures. However, the crucial step is obtaining the best samples for molecular analysis. Archiving and selection of these are the responsibilities of all pathologists even if they are not working at a center with molecular pathological facilities. This review focuses on the features of different types of materials for molecular pathological analysis...

Background: In a patient with pleural effusion, cytological study (CS) is one of the most useful investigations, especially when malignancy is suspected. Instead of applying only CS, the pleural fluid can be further processed using the cell block (CB) technique, which may augment the diagnostic utility. The aim of this study was to compare the diagnostic yields of CS, CB, and the combination of both, regardless of the etiology of pleural effusion. Methods: A cross-sectional study was conducted on patients with pleural effusions who underwent thoracentesis from June 2015 to May 2016...

There is no doubt that organised cervical screening programmes have significantly reduced the rates of cervical cancer by detection and treatment of high-grade cervical intraepithelial neoplasia (CIN2, CIN3). National UK guidelines do not differentiate between CIN2 and CIN3 as separate entities and recommend treatment for both, although a degree of uncertainty exists regarding the natural history of CIN2. This national survey of British Society for Colposcopy and Cervical Pathology members aimed to assess attitudes towards conservative management (CM) of CIN2 in the UK and identify potential selection criteria...
