Multidisciplinary approach for a relapsing goiter with severe tracheal stenosis: a case report in an elderly patient

Total thyroidectomy is considered the gold standard for thyroid benign pathology treatment. Unfortunately, many partial interventions carried out in the past created many complications due to the tendency of the goiter to relapse and the formation of adherences in the anterior region of the neck. A woman 72 years of age with a relapsing goiter and severe respiratory symptomatology underwent thyroidectomy. After thyroid removal, tracheal stenosis persisted, making the positioning of a T silicon prosthesis (Montgomery’s T-tube) necessary. After 60 days, the prosthesis was replaced with a new made out of the same material but with a larger diameter and a softer consistency, which was removed after 4 months. The patient completely recovered her respiratory function and also maintained normal vocal cord activity without any kind of surgical sequelae. The full success was possible because of the involvement of different specialists

Breast Fistula Repair after Autologous Fat Graft: A Case Report

We report the case of a 55-year-old female patient who attended our clinic for the presence of a scar retraction in the upper pole of the left breast as a complication of breast augmentation. In the scar area, we observed an orifice that probing revealed to be a fistula. The patient was referred to surgical intervention under general anesthesia to obtain scar contracture release using autologous fat graft; one month after autologous fat injection, following healing of the fistula, the patient underwent a second surgical procedure to replace the left breast implant. Unexpectedly, two weeks after the surgical procedure, complete healing of the breast fistula within the scar area was observed; this observation was confirmed during the second surgical step for left breast implant repositioning, when we observed the absence of the fistula orifice in the breast implant cavity. Upon clinical examination at 1-year followup, tissue integrity was preserved. The patient's satisfaction was excellent. We have observed a possible additional effect of fat graft

Sex differences in natural history of cardiovascular magnetic resonance- and biopsy-proven lymphocytic myocarditis

Aims: the role of sex in determining the profile and the outcomes of patients with myocarditis is largely unexplored. We evaluated the impact of sex as a modifier factor in the clinical characterization and natural history of patients with definite diagnosis of myocarditis. Methods and results: we retrospectively analysed a single-centre cohort of consecutive patients with definite diagnosis of myocarditis (i.e. endomyocardial biopsy or cardiac magnetic resonance proven). Specific sub-analyses were performed in cohorts of patients with chest pain, ventricular arrhythmias, and heart failure as different main symptoms at presentation. The primary outcome measure was a composite of all-cause mortality or heart transplantation (HTx). We included 312 patients, of which 211, 68% of the whole population, were males. Despite no clinically relevant differences found at baseline presentation, males had a higher indexed left ventricular end-diastolic volume (62 ± 23 mL/m2 vs. 52 ± 20 mL/m2, P = 0.011 in males vs. females, respectively) at follow-up evaluation. At a median follow-up of 72 months, 36 (17%) males vs. 8 (8%) females experienced death or HTx (P = 0.033). Male sex emerged as predictors of all-cause mortality or HTx in every combination of covariates (HR 2.600; 1.163–5.809; P = 0.020). Results were agreeable regardless of the main symptom of presentation. Conclusions: in a large cohort of patients with definite diagnosis of myocarditis, females experienced a more favourable long-term prognosis than males, despite a similar clinical profile at presentation

Negative ozone anomalies at a high mountain site in northern Italy during 2020: a possible role of COVID-19 lockdowns?

Several studies investigated the possible impacts of the restriction measures related to the containment of the spread of the COrona VIrus Disease (COVID-19) to atmospheric ozone (O3) at global, regional, and local scales during 2020. O3 is a secondary pollutant with adverse effects on population health and ecosystems and with negative impacts on climate, acting as greenhouse gas. Most of these studies focused on spring 2020 (i.e. March–May) and on observations in the planetary boundary layer (PBL), mostly in the vicinity of urban agglomerates. Here, we analyzed the variability of O3 above the PBL of northern Italy in 2020 by using continuous observations carried out at a high mountain WMO/GAW global station in Italy (Mt. Cimone–CMN; 44°12' N, 10°42' E, 2165 m a.s.l.). Low O3 monthly anomalies were observed during spring (MAM) and summer (JJA), when periods of low O3 intertwined with periods with higher O3, within climatological ranges. A similar variability was observed for O3 precursors like NO2 and 15 anthropogenic non-methane volatile organic carbons, but the systematic O3 anomalies were not reflected in these variables. The analysis of meteorological variables and diel O3 cycles did not suggest major changes in the vertical transport related to the thermal circulation system in the mountain area. The analysis of five days back-trajectories suggested that the observed O3 anomalies cannot be explained by differences in the synoptic-scale circulation with respect to the previous years alone. On the other hand, the characterization of two transport patterns (i.e. air masses from the regional PBL or from the free troposphere) and the analysis of back-trajectories suggested an important contribution of transport from the continental PBL during the periods with the lowest O3 at CMN. When proxies of air mass transport from the regional PBL are considered, a lower NOx content was pointed out with respect to the previous years, suggesting a lower O3 production in a NOx-limited atmosphere. Our study suggested for the first time that, during MAM and JJA 2020, the reduced anthropogenic emissions related to the COVID-19 restrictions lowered the amount of this short-lived climate forcer/pollutant at remote locations above the PBL over northern Italy. This work suggests the importance of limiting anthropogenic precursor emissions for decreasing the O3 amount at remote locations and in upper atmospheric layers

The influence of some dietary components on intestinal microbiota

The gut microbiota is the set of symbiotic microorganisms that resides in our intestine. The interaction between the gut microbiota and the mucosal immune system can be altered as a result of shifts in the composition or metabolic activity of the intestinal microflora. Recent studies establish that diet is one of the main involved factors in determining the microbial composition of the gut suggesting its role as external factor able to promote the onset of specific diseases by disrupting the immune homeostasis. Starting from the evidence that the 57% of the gut microbiota’s entire variation are due to dietary alterations this review aims at providing an overview of the positive impact of some dietary components on gut microbiota composition

THE INTESTINAL ECOSYSTEM AND PROBIOTICS

The term "probiotic" comes from the greek "pro bios" and means "pro life": Nowadays, an increasing number of pharmaceutical preparations and functional foods are enriched with probiotics and for the patients it is increasingly important to receive information needed to know how to orient in the choice. The benefits from probiotics are many and include the modulation of the intestinal microflora (stimulation of beneficial bacteria and inhibition of pathogens), the support of bowel function and the stimulation of the immune system. This broad spectrum of beneficial effects to maintain efficient the intestinal ecosystem. Therefore, probiotics are an useful tool to prevent the formation of disorders and/or pathologies. The aim of this review is to describe the intestinal ecosystem and how probiotics could be effective in the treatment and prevention of possible alterations

Comparison between Rapid Intraoperative and Central Laboratory Parathormone Dosage in 12 Kidney Transplant Candidates

Background The rapid intraoperative parathormone (PTH) and at central laboratory PTH dosage gives similar results. The central laboratory provides results in longer times and higher costs. Intraoperative measurement can reduce time and costs during parathyroidectomy. Methods Twelve patients undergoing parathyroidectomy for hyperparathyroidism renal transplant candidates were included. Diagnosis was made by laboratory tests (serum calcium, PTH) and imaging techniques (ultrasonography and scintigraphy). All patients presented PTH levels of >400 pg/mL (the limit value to be maintained in list for kidney transplantation) and resistant to medical therapy. For each patient, 2 blood samples were collected before surgery at anesthesia induction for PTH testing intraoperative (rapid assay) and central laboratory, and 10 minutes after the removal of each gland. The times from collection-processing to communication to the surgeon of the results were compared for both the methods. It was considered successful the abatement of PTH of ≥70% at rapid intraoperative testing and consequently surgical intervention stopped before communication of central laboratory PTH testing. Results The average time of reporting the test results of the central laboratory was 41.5 minutes (SD ± 9), whereas with the rapid intraoperative PTH (ioPTH) testing the average time was 9.9 minutes (SD ± 2.02). An average of 33.6 minutes of the duration per intervention (SD ± 10.27) were virtually saved with the use of ioPTH testing. The 2 values of the Pearson correlation (ρ) of 0.99 obtained (for baseline) and 0.975 (for the 10-minute) lead us to conclude that there is an excellent correlation between the series of data. Conclusions Rapid ioPTH testing, owing to its accuracy, permits a dramatic reduction of operating time for patients with secondary hyperparathyroidism that need to be treated before inclusion on the waiting list

A complex case of fatal calciphylaxis in a female patient with hyperparathyroidism secondary to end stage renal disease of graft and coexistence of haemolytic uremic syndrome

Background. Calciphylaxis is a potentially fatal complication of persistent secondary hyperparathyroidism; its cause is still not clear. Unfortunately there is no close relation in severity of clinical picture, serological and pathological alteration. For this reason the prognosis is difficult to establish. Administration of sodium thiosulphate may reduce the precipitation of calcium crystals and improve the general clinical conditions before surgical parathyroidectomy, which seems the only therapeutic approach able to reduce the mortality risk in these patients. Methods and Results. A 60 year old female patient suffering from End Renal Stage Disease, on haemodialysis from 2001 due to the onset of haemolytic uremic syndrome, underwent a kidney transplant in April 2008. After transplantation there was a recurrence of the haemolytic uremic syndrome, with temporary worsening of the graft. Six months later there was a definite loss of graft and return to dialysis treatment. On April 2010 a severe systemic calciphylaxis related to secondary hyperparathyroidism was diagnosed. The patient underwent parathyroidectomy but, because of the unimproved clinical picture, treatment with sodium thiosulphate was initiated. There was only improvement in cutaneous lesions. The worsening general clinical condition of the patient caused death due to general septic complications. Conclusions. The coexistence of haemolytic uremic syndrome and secondary hyperpathyroidism makes the prognosis poor and, in this case, therapy, which counteracts calcium crystals precipitation, has no effect. Preventive parathyroidectomy can be considered as the only possible treatment

A misunderstood intestinal perforation believed acute pancreatitis: a case report

Acute pancreatitis represents one, possible but rare, of the several complications of laparoscopic cholecystectomy. In the case reported, a 31-year-old female patient complained of abdominal pain after laparoscopic cholecystectomy. The clinical picture, the high values of serum amylase, lipase and white blood cell count and the subsequent abdominal computed tomography (CT) led to diagnose an acute biliary pancreatitis. This was pharmacologically treated, but the patient worsened in a few days. A contrastenhanced CT showed the presence of free air and effusion into the peritoneal cavity. The patient was submitted to another intervention, which revealed a 1-cm jejunal perforation. The injured loop was then repaired and the patient discharged after three days. The cause remains obscure but it was likely due to umbilical trocar insertion. An upper quadrant abdominal pain with elevated amylase and lipase serum concentration, not always indicate the presence of an acute pancreatitis but could be associated to a difficult case of intestinal perforation
