Heart failure as a first sign of disseminated tuberculosis.

Tuberculous pericarditis is a rare extra-pulmonary manifestation of tuberculosis observed mainly in developed countries. It usually presents with concomitant tuberculous infection at a different site and, due to the lack of clinical specificity, diagnosis can be difficult. Thus, a diagnostic delay is frequent, entailing increased morbidity and mortality. The authors present a case of disseminated tuberculosis with predominantly cardiac symptoms with multiple negative samples for Mycobacterium tuberculosis, which evolved to constrictive pericarditis. With this case report, the authors emphasize the demand for a high index of suspicion for achieving a diagnosis and the importance of a multidisciplinary approach.

A case report of idiopathic Hemophagocytic lymphohistiocytosis in an immunocompetent adult.

Hemophagocytic lymphohistiocytosis poses a diagnostic dilemma due to the absence of specific clinical and laboratory findings, especially in adults. Despite greater recognition of the disease, secondary idiopathic forms are still reported.

Not Always (and Only) Heart Failure-A Case Report of Primary Pleural Lymphoma in an Elderly Patient.

Pleural involvement in Non-Hodgkin Lymphoma (NHL) is well documented, but primary pleural lymphomas are extremely rare, occurring mostly in immunosuppressed patients or associated with chronic pleural inflammation. Nevertheless, the pathogenesis and therapeutic approaches to counteract primary pleural lymphomas are still matter of debate. The authors present the clinical case of an 81-year-old female with respiratory and constitutional symptoms. A valvular heart disease and bilateral pleural effusion were known. The study carried out showed a large right pleural effusion; the fluid analysis was compatible with Diffuse Large B-cell Lymphoma (DLBCL), and two lymphomatous masses with pleural origin were found at the ipsilateral hemithorax. Primary pleural lymphoma was considered and chemotherapy was initiated with a good response and evolution. The authors report this remarkable clinical case because of its rarity, its excellent clinical evolution and the absence of an immunodeficiency context.

An Unexpected Favourable Evolution of Advanced Stage Cirrhosis.

The elimination of the aetiological factors causing liver injury is an important cornerstone in preventing progression and increasing survival in patients with cirrhosis. The authors present the case of a 63-year-old woman with a history of long-term alcohol abuse and consequent liver cirrhosis. Over the years, the patient presented progressive deterioration with severe malnutrition and had multiple hospital admissions due to decompensated cirrhosis, including refractory ascites, variceal bleeding and an extensive portal vein thrombosis (PVT). Anticoagulant therapy was not initiated due to a high risk of variceal bleeding. She eventually became abstinent, but PVT precluded a liver transplant. Over the following 10 years, her performance status gradually improved, with no new decompensation episodes and liver function normalization, although refractory ascites persisted. Abdominal CT showed spontaneous recanalization of the portal vein and a transjugular intrahepatic portosystemic shunt (TIPS) procedure was performed with gradual improvement of ascites. In this atypical case, an unexpected favourable evolution of advanced stage cirrhosis was observed with long-term improvement in clinical status and liver function, resulting in an estimated 10-year cumulative mortality rate of 99.98% and highlighting the importance of abstinence. Unexpectedly, spontaneous complete repermeabilization of the PVT was also observed, despite its extent and the absence of anticoagulation therapy. LEARNING POINTS: The elimination of the aetiological factors causing liver injury is the cornerstone in preventing decompensation and improving prognosis in patients with cirrhosis.Spontaneous complete recanalization of the portal vein may occur.A transjugular intrahepatic portosystemic shunt (TIPS) is effective in managing some of the major complications of portal hypertension, such as refractory ascites, and provides secondary prophylaxis of oesophageal variceal haemorrhage.

T-Cell/Histiocyte-Rich Large B-Cell Lymphoma: A Challenging Diagnosis.

Epstein-Barr virus (EBV) is a double-stranded virus that shows tropism for B-cell lymphocytes. EBV-infected patients usually present with tonsillitis/pharyngitis, cervical lymphadenopathy and fever, but an atypical presentation can mimic lymphoproliferative disease. We present the case of a 77-year-old woman with asthenia, fever, oral ulcers and peripheral lymphadenopathy. After extensive evaluation, including anatomopathological and immunocytochemical examination of excisional lymph node biopsy samples, it was still not clear whether the patient had EBV infection or diffuse large B-cell lymphoma. In this case report, the authors describe how it can be difficult to differentiate between two different, although related, entities, making diagnosis of lymphoma highly challenging. LEARNING POINTS: Lymph node biopsy findings may result in lymphoma being misdiagnosed as acute Epstein-Barr virus infection.Immunophenotypic analysis can occasionally be insufficient to establish the clonal nature of the disease.Timely diagnosis of lymphoma is necessary so that immunochemotherapy can be initiated and clinical improvement achieved.

Sclerosing Mesenteritis and Disturbance of Glucose Metabolism: A New Relationship? A Case Series.

BACKGROUND: Sclerosing mesenteritis is an idiopathic inflammatory and fibrotic disease that affects the mesentery. It is a rare disease, with the total number of reported cases in the literature ranging from 122 to 300. It mainly affects men in the sixth decade of life, and its etiology remains unknown. Clinical presentation is variable, but it is frequently asymptomatic. Diagnosis is often made by computed tomography (CT) scan, although biopsy may be needed for confirmation. An association between other diseases (e.g., neoplasms) and sclerosing mesenteritis has been described, but the relationship between the latter and glucose changes is not disclosed in the currently available literature. CASE REPORT: Five cases of sclerosing mesenteritis and glucose metabolism disorders (impaired fasting glucose and type 2 diabetes mellitus) were retrospectively collected and analyzed. The mean age was 65 ± 9.3 years, 80% were male, and all patients were white. Three patients were asymptomatic and the other 2 (40%) had non-specific chronic abdominal pain. Blood tests revealed normal inflammatory parameters (mean HbA1c was 6.4% and fasting blood glucose was 140 mg/dL). The diagnosis was made by abdominal CT scan. The 2 symptomatic patients underwent therapy with colchicine 1 mg/day, with clinical improvement. During the mean 43-month follow-up period, there was no symptomatic progression, thereby maintaining the usual benign course of this condition. CONCLUSIONS: Sclerosing mesenteritis has only been described in small series and isolated cases, but its diagnosis is becoming more common due to greater access to diagnostic methods and higher awareness of the disease in the medical community. Furthermore, despite the small sample size, we describe a possible association between glucose metabolism impairment and sclerosing mesenteritis.
