Symptoms of anxiety and mood disturbance alter cardiac and peripheral autonomic control in patients with metabolic syndrome

Previous investigations show that metabolic syndrome (MetSyn) causes sympathetic hyperactivation. Symptoms of anxiety and mood disturbance (AMd) provoke sympatho-vagal imbalance. We hypothesized that AMd would alter even further the autonomic function in patients with MetSyn. Twenty-six never-treated patients with MetSyn (ATP-III) were allocated to two groups, according to the levels of anxiety and mood disturbance: (1) with AMd (MetSyn + AMd, n = 15), and (2) without AMd (MetSyn, n = 11). Ten healthy control subjects were also studied (C, n = 10). AMd was determined using quantitative questionnaires. Muscle sympathetic nerve activity (MSNA, microneurography), blood pressure (oscillometric beat-to-beat basis), and heart rate (ECG) were measured during a baseline 10-min period. Spectral analysis of RR interval and systolic arterial pressure were analyzed, and the power of low (LF) and high (HF) frequency bands were determined. Sympatho-vagal balance was obtained by LF/HF ratio. Spontaneous baroreflex sensitivity (BRS) was evaluated by calculation of α-index. MSNA was greater in patients with MetSyn + AMd compared with MetSyn and C. Patients with MetSyn + AMd showed higher LF and lower HF power compared with MetSyn and C. In addition, LF/HF balance was higher in MetSyn + AMd than in MetSyn and C groups. BRS was decreased in MetSyn + AMd compared with MetSyn and C groups. Anxiety and mood disturbance alter autonomic function in patients with MetSyn. This autonomic dysfunction may contribute to the increased cardiovascular risk observed in patients with mood alterations.     

Spleen sizing by ultrasound scan and risk of pneumococcal infection in patients with chronic GVHD: preliminary observations.

Encapsulated bacteria infections (EBI) can cause severe complications after BMT, usually occurring in patients with chronic GVHD (cGVHD) and attributed to functional hyposplenism. Using ultrasound (US) scan, we measured spleen size in 22 patients transplanted from HLA identical siblings, with or without cGVHD. No patient had received TBI, spleen irradiation or penicillin prophylaxis. Results were correlated with occurrence of EBI during a mean follow-up of 55 months (range 7-93). In the group without cGVHD, the difference between pre- and post-BMT spleen longitudinal diameters was not significant, and no patient developed EBI. In the cGVHD group, post-BMT spleen longitudinal diameters were significantly smaller than those pre-BMT (9.1+/-1.6 vs. 12.3+/-2.2; P = 0.0005). Out of four patients with cGVHD who showed a major spleen size reduction, two developed a severe infection (an overwhelming sepsis and a pneumococcal meningitis). In our small series, we found a borderline relationship between spleen size reduction and duration of cGVHD (P = 0.06), as well as an increased risk of life-threatening infection in patients with extensive cGVHD and hyposplenism as detected by US scan. We conclude that US scan may be useful to detect spleen size reduction following allogeneic BMT and that penicillin prophylaxis is to be strongly recommended in patients with extensive cGVHD and spleen size reduction, even in those who have not received total body or spleen irradiation.     

Liver transplantation from active COVID-19 donors: A lifesaving opportunity worth grasping?

COVID-19 pandemic dramatically impacted transplantation landscape. Scientific societies recommend against the use of donors with active SARS-CoV-2 infection. Italian Transplant Authority recommended to test recipients/donors for SARS-CoV-2-RNA immediately before liver transplant (LT) and, starting from November 2020, grafts from deceased donors with active SARS-CoV-2 infection were allowed to be considered for urgent-need transplant candidates with active/resolved COVID-19. We present the results of the first 10 LTs with active COVID-19 donors within an Italian multicenter series. Only two recipients had a positive molecular test at LT and one of them remained positive up to 21 days post-LT. None of the other eight recipients was found to be SARS-CoV-2 positive during follow-up. IgG against SARS-CoV-2 at LT were positive in 80% (8/10) of recipients, and 71% (5/7) showed neutralizing antibodies, expression of protective immunity related to recent COVID-19. In addition, testing for SARS-CoV-2 RNA on donors’ liver biopsy at transplantation was negative in 100% (9/9), suggesting a very low risk of transmission with LT. Immunosuppression regimen remained unchanged, according to standard protocol. Despite the small number of cases, these data suggest that transplanting livers from donors with active COVID-19 in informed candidates with SARS-CoV-2 immunity, might contribute to safely increase the donor pool.

     

Florid papillomatosis of the male nipple

The authors present a case of an adenoma of the nipple in a 61-year-old man who reported a 6-month history of nodularity and itching at his left nipple. Examination revealed a firm, well-defined, vascularized tumor measuring .8 cm that altered the normal anatomy of the nipple. A total excision of the nipple and areola was performed. The histological diagnosis was adenoma of the nipple. No recurrent tumor has been observed during 4 years of postoperative follow-up. An adequate excision of the lesion is curative without any risk of recurrence or development of malignancy.     

Atypical neoglottis after supracricoid laryngectomy: a morphological and functional analysis

The objective of this study was to analyze atypical neoglottis after supracricoid subtotal laryngectomy (SSL) from a morphological and functional point-of-view using retrospective case series reviewin a Tertiary university referral center setting. From May 2003 until January 2010, 106 patients underwent SSL (CHEP, CHP, THEP, THP) for laryngeal cancer, in the Otolaryngology Department of the University Hospital of Modena. We performed a retrospective analysis of recorded videos in our database of patients who underwent SSL. Patients with atypical neoglottis were included in the study. Six patients with atypical neoglottis were identified and morphologically evaluated. The functional outcomes were collected and analyzed. Atypical neoglottis may form after SSL, in particular in the case of CHEP. In most cases, these atypical conformations are due to anomalous positioning of the epiglottis, or involvement of the lateral pharyngeal wall in the sphincteric and vibratory function of the neoglottis. Atypical neoglottis formation seems to guarantee adequate functional outcomes in terms of vocal and swallowing performance.     

Barrett’s esophagus and Cornelia de Lange Syndrome

Aim: To review the records of Cornelia de Lange Syndrome (CDLS) children, affected by Gastro‐oesophageal reflux disease (GERD), to detect the presence of Barrett’s Esophagus (BE). Methods: A total of 62 CDLS patients were investigated for GERD (1 month–35 years). In all of them a pH‐metry, an upper endoscopy with multiple biopsies and a complete radiologic digestive evaluation were carried out. BE was diagnosed in case of replacement of oesophageal mucosa by specialized intestinal‐type columnar mucosa. Anti‐reflux surgery was considered in case of persistence of BE after medical therapy. Follow‐up (mean 3.5 years) consisted in endoscopy every 6 months . Results: Gastro‐oesophageal reflux disease was found in 50 CDLS patients (80%) and BE in six of them (12% of the GERD group, 9.6% of the entire population, mean age 17 years, range 6–32 years). A short segment BE was observed in three patients, a long one in two patients and an infiltrating adenocarcinoma of the lower oesophagus in one patient. Conclusions: A higher frequency of BE in CDLS patients than in a normal population is found. A delayed diagnosis because of atypical GERD symptoms and an altered intestinal motility as a result of neurological impairment can be recognized as the main cause.
