Volumetric analysis of maxillary sinus and assessment of various sinonasal anatomic variants on multi-detector computed tomography (MDCT) and their association with chronic rhinosinusitis.

Objectives: The study aimed to evaluate the relationship between maxillary sinus volume and various sinonasal anatomical variants, as detected by multi-detector computed tomography, and their associations with chronic rhinosinusitis (CRS).

Material And Methods: A case-control study was conducted with 103 patients presenting with chronic sinonasal symptoms (cases) and 50 asymptomatic individuals (controls). A 128-slice computed tomography scanner was used to measure maxillary sinus volume and assess anatomical variants, such as a deviated nasal septum (DNS), concha bullosa (CB), and agger nasi cells.

Quantification of joint mobility limitation in adult type 1 diabetes.

Aims: Diabetic cheiroarthropathies limit hand mobility due to fibrosis and could be markers of a global profibrotic trajectory. Heterogeneity in definitions and lack of a method to measure it complicate studying associations with organ involvement and treatment outcomes. We measured metacarpophalangeal (MCP) joint extension as a metric and describe magnetic resonance (MR) imaging determinants of MCP restriction.

A case-control study addressing the population of epidermal and dermal inflammatory infiltrate including neural milieu in primary prurigo nodularis using S-100 and toluidine blue stain and its therapeutic implications.

Background: The pathogenesis of prurigo nodularis (PN) is considered to be multifactorial, with numerous cells and cytokines confabulating to produce an aberrant immune response.

Methods: A cross-sectional observational study was done in cases of untreated primary prurigo nodularis cases with histopathological assessment in 49 cases from lesional and nonlesional skin with assessment of epidermal and dermal changes, dermal infiltrate, S-100 and toluidine blue staining to assess the expression of nerve and mast cells.

Results: The most common histological changes seen in lesional skin were hyperkeratosis (98%), irregular hyperplasia (69.

Kimura's disease: A short study of cytomorphologic features with its differential diagnosis and review of literature.

Kimura's disease (KD) is a chronic inflammatory disorder of unknown etiology, endemic in Asia. The typical clinical manifestations include a triad of painless unilateral cervical lymphadenopathy or subcutaneous masses predominantly in the head-and-neck region, blood and tissue eosinophilia, and elevated serum immunoglobulin (Ig) E levels. Many conditions including benign and malignant may mimic KD clinically.

Multiple tuberous xanthomas diagnosed on fine-needle aspiration cytology - Report of a rare case.

Xanthomas are papulonodular skin lesions present in lipoprotein metabolism disorders, which result in cholesterol deposits in subcutaneous tissue, tendons, ligaments, periosteum, etc. A 28-year-old male presented with multiple soft-tissue swellings, prominently over joints. Fine-needle aspiration (FNA) from multiple sites had similar appearance with foamy histocytes and giant cells.

Comparison of hematologic abnormalities between hospitalized coronavirus disease 2019 positive and negative patients with correlation to disease severity and outcome.

Peripheral blood smear (PBS) changes in coronavirus disease 2019 (COVID-19) are diverse and have been reported in the literature in the form of case series with relatively smaller sample sizes and with a handful of studies showing the association between PBS and clinical severity. This study aims to highlight the numerical and morphological changes in peripheral blood of COVID-19 patients and to compare the same in intensive care unit (ICU) and non-ICU settings as well as with disease severity and outcome. The study included 80 COVID-19 positive (41 ICU and 39 non-ICU) patients and 32 COVID-19 negative ICU patients.

Aspiration cytology of facial nerve schwannoma of parotid gland: A rare diagnosis.

Schwannoma is a benign nerve sheath tumour rarely found in the head and neck region and much less commonly found in the intraparotid facial nerve. It is a slow-growing encapsulated tumour arising from differentiated Schwann cells or axonal nerve sheath. It can occur anywhere along the course of the facial nerve.

A Prospective Study Examining the Effect of Selected Topical and Systemic Drugs on Pruritus Grading System Score and STAT 6 Expression in Patients of Prurigo Nodularis.

Background: Prurigo nodularis (PN) is a chronic dermatologic condition presenting as multiple papulonodular lesions occurring with intense pruritus. Though numerous agents (topical, systemic, phototherapy and biological drugs) have been tried, the outcomes are variable.

Objectives: The aim of this study was to assess the role of topical and systemic therapies in primary PN by comparing the Pruritus Grading System (PGS) score at baseline and 1 month post-therapy.

A prospective study examining the expression of STAT 1, 3, 6 in prurigo nodularis lesions with its immunopathogenic and therapeutic implications.

Background: Prurigo nodularis (PN) is a chronic dermatologic condition manifesting as multiple papulonodular lesions occurring on the background of intense pruritus. PN could be primary or secondary. The exact immune pathogenesis of PN is not yet clear, and multiple pathways are proposed with the JAK-STAT pathway rarely being investigated.

Coronary arteritis as a cause of sudden cardiac death in a young girl.

A case of probable coronary arteritis in a young girl who died suddenly and unexpectedly is presented. The histologic presentation of the disorder is discussed, especially the differential diagnosis of arteritis of the coronary arteries with an emphasis on tuberculosis (TB). TB myocarditis with or without concomitant lung involvement is rare, and tubercular coronary arteritis without underlying pulmonary Koch's disease is all the rarer.

Comparative evaluation of squash smear and frozen section in the intraoperative diagnosis of central nervous system tumours.

Background: The squash smear technique was introduced into intra-operative neurosurgical diagnosis as early as 1930. It is becoming increasingly popular in the diagnosis of central nervous system (CNS) lesions, and is fairly accurate even with a small sample. The current study assesses the accuracy and utility of the squash smear and frozen section (FS) techniques in intraoperative consultations.

Cytomorphological spectrum of cysticercosis: A study of 26 cases.

Background: Cysticercosis is a systemic parasitic disease caused by the larval stage of Taenia solium. It is the most common parasitic disease worldwide. Fine needle aspiration cytology can play an important role in prompt recognition of this disease.

Cytological diagnosis of microfilariae in clinically unsuspected cases: A retrospective review of 12 cases.

Background: Filariasis is a major health problem in India. Despite the high prevalence, microfilariae are rarely found in cytology smears. Most of the cases are incidentally found, solely or in association with other pathologies.

A Rare Case of Epithelioid Myofibroblastoma of Breast Mimicking Lobular Carcinoma on Trucut Biopsy: a Diagnostic Pitfall and Literature Review.

Epithelioid myofibroblastoma of the breast is a rare benign stromal tumor occurring in the postmenopausal females and elderly males. We report one such case in a 65-year-old female who underwent trucut biopsy from a well-defined right breast lump, which was misinterpreted as invasive lobular carcinoma on histology. Tumor showed mild to moderately pleomorphic tumor cells arranged in single file pattern, loosely dispersed and focally in sheets with inconspicuous nucleoli embedded in a fibrotic and hyalinized stroma.
