Thoracic Epidural Chronic Inflammatory Lesion: A Case Report and Review of Literature.

Chronic inflammatory lesions (CIL) in the body are rare and inflammatory pseudotumor (IPT) is a subtype of CIL. Spine is an uncommon location of CIL, with most cases reported in the thoracic spine. Our objective was to review the current literature on IPT.

A 58-Year-Old Man With Hemoptysis After COVID-19 Infection.

A 58-year-old man presented to us with a 1-week history of high-grade fever and progressive dry cough. Four weeks before his presentation, he was diagnosed with COVID-19 infection and needed non-ICU hospital admission with no supplemental oxygen requirements for 6 days and was treated with a 5-day course of remdesivir and 3 weeks of dexamethasone. His steroid dose was commenced on dexamethasone 12 mg bid (four times the recommended dose) for 14 days and then gradually tapered over the remaining 7 days.

Long-term outcome of adjunctive Gamma Knife radiosurgery in skull-base chordomas and chondrosarcomas: An Indian experience.

Skull-base chordomas (CD) and chondrosarcomas (CS) are locally-invasive tumors, have similar clinical presentations, while differing in their nature of growth and outcomes. In this study, we compare the long-term outcomes of Gamma Knife Radiosurgery (GKRS) as an adjunctive treatment modality for residual skull-base CD and CS. A retrospective analysis of clinico-radiological, pathological, radiotherapeutic and outcome data was carried out in patients who underwent adjunctive GKRS for residual skull-base CD and CS at P D Hinduja Hospital, Mumbai, between 1997 and 2020.

Do additional colonoscopic biopsies increase the yield of Mycobacterium tuberculosis culture in suspected ileo-colonic tuberculosis?

Background: Isolation of Mycobacterium tuberculosis on culture is vital for differentiating intestinal tuberculosis (ITB) from Crohn's disease (when histology is not diagnostic) and for diagnosis of multidrug-resistant tuberculosis. The current yield of TB culture (< 50%) from colonoscopic biopsy tissue is not satisfactory.

Aim: To determine whether more colonoscopic biopsies can increase the yield of TB culture in patients with ITB.

Nontuberculous mycobacterial infection of the musculoskeletal system in immunocompetent hosts.

Background: Nontuberculous mycobacteria (NTM) were considered saprophytic organisms for many years but now are recognized as human pathogens. Although humans are routinely exposed to NTM, the rate of clinical infection is low. Such infections usually occur in the elderly and in patients who are immunocompromised.

Bednar Tumor: An Uncommon Entity.

Bednar tumor is an uncommon variant of dermatofibrosarcoma protuberans. Also known as pigmented dermatofibrosarcoma protuberans, this tumor is of intermediate grade. It is seen in adults and has a predisposition to affect the shoulder region.

Colorectal cancers in ulcerative colitis from a low-prevalence area for colon cancer.

Aim: To determine the incidence and risk factors for colorectal cancer (CRC) in patients with ulcerative colitis from a low prevalence region for CRC.

Methods: Our prospective database yielded a cohort of 430 patients [age: 44 ± 14.6 years; 248 men (57.

Whipple's disease.

A 74 year old male patient with weight loss, diarrohea, loss of appetite, anemia, thrombocytopenia and culture negative endocarditis was diagnosed to have Whipple's disease. We are reporting this case, as it is a rare disease with fewer than 1000 validated cases reported in literature.

Hermansky-Pudlak syndrome.

We present a rare disease condition Hermansky-Pudlak syndrome in a 33-year-old male. He was born of a consanguineous marriage, had occulo-cutaneous albinism, nystagmus, decreased visual acuity, refractory errors, pulmonary fibrosis and granulomatous inflammation of the colon. In spite of all the classical features of this genetic disorder he was labeled to have disseminated tuberculous infection with a drug resistant strain for many years till the actual diagnosis was made on the basis of a strong clinical suspicion.

Osteoarticular tuberculosis--diagnostic solutions in a disease endemic region.

Background: We conducted a study of osteoarticular tuberculosis in patients from private and public settings in a disease endemic area. Our objective was to assess the role of mycobacterial culture and polymerase chain reaction (PCR) in the diagnosis of osteoarticular tuberculosis (TB) in settings where only clinical and imaging diagnosis form the basis for treatment.

Methodology: Ninety-three consecutive specimens collected from clinically suspected patients of osteoarticular TB were screened for bacterial culture, mycobacterial culture and in-house nested PCR.

Gamma knife radiosurgery in jugular foramen endolymphatic sac adenocarcinoma.

A 41-year-old male presented to us with a history of right-sided temporal headache and ear discharge. MRI revealed an extra-axial space-occupying lesion in the region of the right jugular foramen. The patient was operated upon and a radical excision of the tumor was performed.

Acanthamoeba encephalitis in patient with systemic lupus, India.

We report a fatal case of encephalitis caused by Acanthamoeba in a 24-year-old woman from India with systemic lupus erythematosus. Diagnosis was made by identification of amebas in brain sections by immunofluorescence analysis and confirmed by demonstrating Acanthamoeba mitochondrial 16S rRNA gene DNA in brain tissue sections.

Hepatic tuberculosis in absence of disseminated abdominal tuberculosis.

Liver involvement in tuberculosis in absence of miliary tuberculosis is rare. This study was performed to analyse the spectrum and response to treatment of hepatic tuberculosis in the absence of miliary abdominal tuberculosis. Retrospective analysis of seven cases of hepatic tuberculosis without miliary abdominal tuberculosis who presented at the single tertiary referral center were analyzed.

Co-existence of peri-ampullary carcinoma with peripancreatic tuberculous lymphadenopathy.

Context: Pancreatic tuberculosis and peripancreatic tuberculous lymphadenitis are rare, mimicking various pathologies of the pancreas. The coexistence of peri-ampullary malignancy with peripancreatic tuberculous lymphadenitis has not been reported.

Case Report: We present the case of a young woman who had been operated on with a preoperative diagnosis of peri-ampullary adenocarcinoma in whom a frozen section of regional lymph nodes revealed tuberculosis.

Autoimmune hepatitis: a study of 50 patients.

Introduction: Autoimmune hepatitis (AIH) is a well-defined entity in the West but there are sparse Indian data on this disease.

Aim: To study the clinical profile and response to treatment of Indian patients with AIH.

Methods: This is a part retrospective and part prospective study of 50 patients (median age 48 years, range 11-82; 43 women) seen between 1995 to 2001, diagnosed to have AIH as per the revised scoring system.

AIDS-associated Kaposi's sarcoma in a heterosexual male--a case report.

A 39 year old married heterosexual male presented with extensive purpuric macules, papules, and lichenoid plaques scattered over his skin and mucocutaneous surfaces for one year. The lesions were larger in both his groins, and were associated with lymphedema of his penis and scrotum. His serology for the HIV-1 virus was positive.
