Challenges in Diagnosis and Clinical Management of COVID-19 in Patient with B-Cell Chronic Lymphocytic Leukemia (CLL): Report of One Case.

We report here a case of a patient affected by B-cell chronic lymphocytic leukemia (CLL) that developed COVID-19 during the actual SARS-CoV-2 outbreak. The coexistence of CLL and COVID-19 raises many questions regarding the possible increased risk of developing COVID-19 among patients with CLL, the problems in managing therapies for both diseases and, above all, the difficulties in diagnosing COVID-19 in patients affected by CLL. In our patient, an 84-year-old man, the recognition of COVID-19 was delayed because of its atypical clinical presentation and technical problems related to the methods used for the diagnosis.

Altered autonomic cardiac regulation in individuals with Down syndrome.

We tested the hypothesis that individuals with Down syndrome, but without congenital heart disease, exhibit altered autonomic cardiac regulation. Ten subjects with Down syndrome (DS) and ten gender-and age-matched healthy control subjects were studied at rest and during active orthostatism, which induces reciprocal changes in sympathetic and parasympathetic traffic to the heart. Autoregressive power spectral analysis was used to investigate R-R interval variability.

Effects of mineral-water supplementation on gastric emptying of solids in patients with functional dyspepsia assessed with the 13C-octanoic-acid breath test.

Background/aims: Functional dyspepsia is a major problem in terms of prevalence and drug-therapy expenditures. In dyspeptic patients the symptoms are frequently caused by delayed gastric emptying. Conventional treatment is often inefficient.

Hepatocellular carcinomas <2 cm in diameter complicating cirrhosis: ultrasound and clinical features in 153 consecutive patients.

Purpose: To determine the frequencies of various echogenicity patterns in 153 consecutive unifocal hepatocellular carcinomas (HCCs) <2 cm detected in cirrhotic livers and to identify their relationships with clinical, laboratory, and microscopic features.

Patients And Methods: The tumors were classified as hypoechoic, hyperechoic, isoechoic, or nodule-in-nodule. Correlation was evaluated between hypoechoic and hyperechoic patterns and the following variables: age, gender, serum alphafetoprotein (AFP), tumor size, ultrasound features of liver parenchyma, cirrhosis etiology, and cyto/histological tumor grading.
