RESUMO
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. Based on the symptoms and the radiological aspect of the lung, the occurrence of COVID-19 was suspected. Repeated tests on oro/nasopharyngeal swabs gave negative results, causing a delay in the diagnosis. Moreover, different methods used to identify the SARS-CoV-2 antibodies in serum gave conflicting results, and only two tests were able to identify SARS-CoV-2 Abs of the IgG type. During the clinical course of unrecognized COVID-19, our patient developed severe complications and did not receive any specific treatment for the two diseases. Recognition of COVID-19 in patients with CLL is a challenging task and the most accurate methods are necessary to overcome the diagnostic difficulties encountered.
RESUMO
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. Mineral-water supplementation is prescribed for the treatment of this condition, but there is no concrete proof of its actual efficacy. The aim of this study was to evaluate the effect of supplementation with mineral waters with high mineral salt contents (Acqua Tettuccio, Acqua Regina, Montecatini Terme) on gastric emptying of solids and symptoms in patients with functional dyspepsia. METHODOLOGY: Eight patients with functional dyspepsia and two healthy (non-dyspeptic) controls were placed on high-mineral-content water supplementation (500 cc/day) for eight days. Before and after completion of the supplementation treatment, patient symptoms were scored and the 13C-octanoic-acid breath test was administered to assess gastric emptying. RESULTS: After the treatment, the dyspeptic subjects presented clear decreases in parameters of gastric emptying (half time and lag time) as well as an improvement in symptom scores. CONCLUSIONS: Health spa treatments based on consumption of waters with a high content of mineral salts seem to be capable of improving gastric emptying of solids in dyspeptics. Longer and longitudinal studies are needed to verify the persistence of this effect.

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. Baroreflex modulation of sinus node was assessed by the spontaneous baroreflex sequences method. No significant differences between DS and control subjects were observed in arterial blood pressure at rest or in response to standing. Also, R-R interval did not differ at rest. R-R interval decreased significantly less during standing in DS vs. control subjects. Low-frequency (LFNU) and high-frequency (HFNU) (both expressed in normalized units) components of R-R interval variability did not differ between DS and control subjects at rest. During standing, significant increase in LFNU and decrease in HFNU were observed in control subjects but not in DS subjects. Baroreflex sensitivity (BRS) did not differ between DS and control subjects at rest and underwent significant decrease on going from supine to upright in both groups. However, BRS was greater in DS vs. control subjects during standing. These data indicate that subjects with DS exhibit reduced HR response to orthostatic stress associated with blunted sympathetic activation and vagal withdrawal and with a lesser reduction in BRS in response to active orthostatism. These findings suggest overall impairment in autonomic cardiac regulation in DS and may help to explain the chronotropic incompetence typically reported during exercise in subjects with DS without congenital heart disease.

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. RESULTS: One hundred and seventeen tumors (76.4%) were hypoechoic, 26 (17.0%) were hyperechoic, 5 (3.3%) were isoechoic, and 5 (3.3%) had nodule-in-nodule patterns. The hyperechoic pattern was more common in patients under 69 years (25.0% vs. 11.3% in those under 69 years or older, P=0.033). Patients with a hyperechoic pattern displayed a trend towards lower AFP levels and higher prevalence of hepatitis C-related cirrhosis. The prevalence of well-differentiated tumors was identical (56.6% and 56.5%) in the hypoechoic and hyperechoic subgroups. AFP was higher than 400 ng/ml in only 11/153 cases (7.2%). CONCLUSIONS: The hyperechoic pattern of HCC is by no means uncommon, particularly in patients under 70. Hyperechogenicity is not related to an increased frequency of well-differentiated tumors. AFP shows limited value as a confirmatory test of small HCC.
