The prognostic value of lung ultrasound score (LUSS) in patients with COVID-19 admitted in Emergency Department: a prospective observational study.

BACKGROUND: The Lung Ultrasound (LUS) is routinely used as a point-of-care imaging tool in Emergency Department (ED) and its role in COVID-19 is being studied. The Lung UltraSound Score (LUSS) is a semi quantitative score of lung damage severity. Alongside instrumental diagnostic, the PaO2/FiO2 (P/F) ratio, obtained from arterial blood gas analysis, is the index used to assess the severity of the acute respiratory distress syndrome (ARDS), according to the Berlin definition. OBJECTIVES: The primary objective of the study was to evaluate a possible correlation between the LUSS score and the P/F Ratio, obtained from the arterial sampling in COVID-19 positive patients. MATERIALS AND METHODS: This was a cross-perspective monocentric observational study and it was carried out in the Emergency Department of the "AOU delle Marche" (Ancona, Italy), from 1 January 2023 to 28 February 2023. The study foresaw, once the patient was admitted to the ED, the execution of the LUS exam and the subsequent calculation of the LUSS score. RESULTS: The sample selected for the study was of 158 patients. The proportion of LUSS ≤4 was statistically higher in those with a P/F >300 (76.2%), compared to those with a P/F ≤300 (13.2%). On the other end, the proportion of LUSS >4 was lower in those who have P/F >300 (23.8%), while it was higher in those who have P/F ≤300 (86.8%). Those patients with a LUSS >4 were 1.76 (95% CI: 1.57 - 1.99) times more likely to have a P/F ≤300, compared to those with LUSS ≤4. The Odds Ratio of having a P/F ≤300 value in those achieving a LUSS >4, compared to those achieving a LUSS ≤4, was 21.0 (95% CI: 8.4 - 52.4). The study identified pO2, Hb and dichotomous LUSS as predictors of the level of P/F ≤300 or P/F >300. DISCUSSION: We found that the LUSS score defined by our study was closely related to the P/F ratio COVID-19 positive patients. Our study presented provides evidence on the potential rule of the LUSS for detecting the stage of lung impairment and the need for oxygen therapy in COVID-19 positive patients.

A functional study of the esophagus in patients with non-cardiac chest pain and dysphagia.

BACKGROUND/AIMS: Nutcracker esophagus and non-specific motility disorders are the main causes of non-cardiac chest pain (NCCP), with gastroesophageal reflux in 60% of cases. Achalasia and diffuse esophageal spasm are the most frequent anomalies described in patients with dysphagia. The goal of this study was to evaluate the occurrence of esophageal body and lower esophageal sphincter motor abnormalities in patients with dysphagia, NCCP, or both. MATERIALS AND METHODS: This study is a retrospective analysis of 716 patients with NCCP and/or dysphagia tested between January 1994 and December 2010. 1023 functional studies were performed, 707 of which were esophageal manometries, 225 esophageal pH-meters, and 44 bilimetries. We divided the patients into three groups: group 1 was composed of patients affected with dysphagia, group 2 with NCCP and group 3 with NCCP and dysphagia. RESULTS: Manometric anomalies were detected in 84.4% of cases (p<0.001). The most frequent esophageal motility alteration was achalasia (36%). The lower esophageal sphincter was normal in 45.9% of patients (p<0.001). In all 3 groups, 80.9%, 98.8%, and 93.8, respectively, of patients showed normal upper esophageal sphincter (p=0.005). CONCLUSION: Our data differs from those of other studies because they were collected from and analyzed by a single tertiary level referral center by a single examiner. This could have eliminated the variability found in different hands and different experiences. The high percentage of symptomatic patients with non-pathologic esophageal motility pattern suggests an unclear origin of the disease, with possible neuromuscular involvement. As a result, these patients may need more-detailed diagnostic studies.

Recurrent cystic lymphangioma of the neck. Case report.

UNLABELLED: Cystic lymphangioma is a rare benign tumor commonly located in the head or neck. Approximately 100 adult cases have been reported in the literature. The etiopathogenesis is unclear, though trauma has been suggested as one of the possible causes. CASE REPORT: We report a case of recurrent cystic lymphangioma arising in an adult who had been successfully treated in our department, leading us to review the literature for a critical examination of our therapeutic choices and the pathological, clinical and therapeutic aspects. We performed a dissection of the cyst respecting anatomical structures.Three days after the surgery, the patient showed a recurrence under the previous site of the excision, We then decided to place a suction drainage under local anesthesia, The suction drainage was removed 25 days later.The post-operative course of the patient showed no signs of recurrence for twenty-four months. DISCUSSION: Complete surgical excision is the treatment of choice in symptomatic patients. In our experience, postoperative suction drainage improved the outcome. Some authors have come out in favor of experimental, non-surgical methods, such as percutaneous sclerotherapy, which they claim offer the most promising results. CONCLUSIONS: In our experience, totally excision of the mass was the treatment of choice but, placing just one suction drainage for weeks for new recurrence resulted in a surprising outcome. In fact, recurrence usually appears within the first nine months in about 10-15% of patients.

Predictive factors of mortality in patients with acute mesenteric ischemia. A retrospective study.

AIM: The aim of this retrospective study was to evaluate the impact of some risk factors on mortality in patients with Acute mesenteric ischemia (AMI). MATERIALS AND METHODS: From September 2003 to August 2011, 200 patients were operated on for bowel infarction at our unit: 149 were included in the study. For each patient, socio-demographic (gender and age) and clinical data (extent of necrosis, predisposing factors, WBC, LDH, comorbidities) were collected from patients' clinical records. RESULTS: Of the 149 patients who underwent surgery, 57 (38.3%) died. A significantly higher mortality was associated with older age (79.9 versus 74.2 years, p < 0.01), higher LDH serum levels (695 versus 636 UI/L, p < 0.01), higher WBC (25.1 versus 22.5 X 103/mm3; p < 0.01), and extent of necrosis (p< 0.01). Otherwise, there was no correlation between comorbidities and mortality. Finally, multivariate analysis confirmed the significantly higher risk of death in patients with right colon and massive small bowel infarction (adjOR= 3.58; 95% CI=1.36-9.42) and intestinal perforation (adjOR=31.1; 95% CI=2.45-395.7). DISCUSSION: The results of our study suggest that the contribution of laboratory tests is limited, even if increased indexes of necrosis (such as LDH) associated with neutrophilic leukocytosis and metabolic acidosis, may help in defining diagnosis/ prognosis, though with low accuracy. CONCLUSIONS: The extent of necrosis and diagnostic delay seem to be the most important prognostic factors even after adjusting for confounding due to age, presence of comorbidities, and laboratory tests (LDH and WBC). KEY WORDS: Acute mesenteric ischemia, Mortality, Predictive factors.

Oligo-antigenic diet in the treatment of chronic anal fissures. Evidence for a relationship between food hypersensitivity and anal fissures.

OBJECTIVES: Patients with chronic constipation due to food hypersensitivity (FH) had an elevated anal sphincter resting pressure. No studies have investigated a possible role of FH in anal fissures (AFs). We aimed to evaluate (1) the effectiveness of diet in curing AFs and to evaluate (2) the clinical effects of a double-blind placebo-controlled (DBPC) challenge, using cow's milk protein or wheat. METHODS: One hundred and sixty-one patients with AFs were randomized to receive a "true-elimination diet" or a "sham-elimination diet" for 8 weeks; both groups also received topical nifedipine and lidocaine. Sixty patients who were cured with the "true-elimination diet" underwent DBPC challenge in which cow's milk and wheat were used. RESULTS: At the end of the study, 69% of the "true-diet group" and 45% of the "sham-diet group" showed complete healing of AFs (P<0.0002). Thirteen of the 60 patients had AF recurrence during the 2-week cow's milk DBPC challenge and 7 patients had AF recurrence on wheat challenge. At the end of the challenge, anal sphincter resting pressure significantly increased in the patients who showed AF reappearance (P<0.0001), compared with the baseline values. The patients who reacted to the challenges had a significantly higher number of eosinophils in the lamina propria and intraepithelial lymphocytes than those who did not react to the challenges. CONCLUSIONS: An oligo-antigenic diet combined with medical treatment improved the rate of chronic AF healing. In more than 20% of the patients receiving medical and dietary treatment, AFs recurred on DBPC food challenge.

Esophageal motility changes after thyroidectomy; possible associations with postoperative voice and swallowing disorders: preliminary results.

OBJECTIVE: Swallowing and voice impairment are common after thyroidectomy. We evaluated short-term functional changes in esophageal motility in a series of patients who had undergone total thyroidectomy. Several studies have investigated these symptoms by means of interviews or questionnaires. STUDY DESIGN: Prospective study. SETTING: Academic research. MATERIALS AND METHODS: Thirty-six consenting patients were prospectively recruited. Eligibility criteria were thyroid volume ≤ 60 mL, benign disease, and age between 18 and 65 years. Exclusion criteria were previous neck surgery, severe thyroiditis, hyperthyroidism, and pre- or postoperative vocal cord palsy. Voice impairment score, swallowing impairment score, lower esophageal sphincter pressure, esophageal motility, upper esophageal pressure, and coordination were evaluated preoperatively and 30 to 45 days after surgery. RESULTS: Postoperative swallowing impairment (appearance or worsening of dysphagia) was found in 20% of patients and voice impairment in more than 30%. Both preoperative and postoperative esophageal motility were similar. All patients showed an average decrease of 25% in upper esophageal pressure, although the pressure was within normal range. Swallowing alterations were associated with upper esophageal incoordination (P < .03), and proximal acid reflux was significantly associated with voice impairment (P < .02). CONCLUSION: After uncomplicated thyroidectomy, decreased upper esophageal pressure may explain both pharyngeal (dysphagia) and laryngeal (vocal impairment) exposure to acid. In the future, proton pump inhibitor therapy protocols should be evaluated.

The use of haemostatic agents in thyroid surgery: efficacy and further advantages. Collagen-Fibrinogen-Thrombin Patch (CFTP) versus Cellulose Gauze.

AIM: To assess the efficacy of two widely used topical haemostatic agents: oxidised regenerated cellulose gauze and Collagen- Fibrinogen-Thrombin Patch in patients undergoing total thyroidectomy. MATERIAL OF STUDY: This was a prospective, comparative, non-randomised study in which consecutive patients undergoing total thyroidectomy for benign disease received standard treatment with no haemostatic agent, cellulose gauze, or CFTP. Main outcome measures were drainage volume 24 hours after surgical procedure and the occurrence of post-operative complications (haematoma, seroma, surgical-site infection). RESULTS: Two hundred seventy-one (271) patients undergoing total thyroidectomy for benign disease: 65 received standard treatment, 60 received cellulose gauze and 146 received CFTP. Seroma was significantly reduced in the CFTP group compared with both the cellulose gauze group (p=0.006) and the standard treatment group (p=0.017). A significant reduction in drainage volume was also observed with CFTP compared with the other two groups (both p<0.001). Drainage volume was also significantly reduced with cellulose gauze versus standard treatment (p<0.001). No septic events were observed after application of CFTP. One hematoma was observed in the non haemostatic group. CONCLUSIONS: Both haemostatic agents reduced the amount of sero-hematic fluid during the first 24 hours post-surgery, with CFTP more effective than oxidized cellulose gauze. The use of haemostatic agents may increase the quality of thyroid surgery, improve patient comfort after surgery, and reduce hospital stay.

Does thyroid surgery for Graves' disease improve health-related quality of life?

PURPOSE: Graves' disease can induce alterations of the psychosocial well-being that negatively influence the overall well-being of patients. Among the current treatments, surgery has limited indications, and its impact on the health-related quality of life has not been well clarified. The aim of this study was to assess the impact of surgery on the quality of life. METHODS: Fifty-seven patients who underwent total thyroidectomy for Graves' disease in our surgical unit between April 2002 and December 2009 were administered a questionnaire concerning four issues: organic alterations and clinical manifestations, neurovegetative system disturbances, impairment of daily activities, psychosocial problems. Patients were retrospectively questioned after thyroidectomy about the presence of these symptoms in both the pre and postoperative periods. RESULTS: There was a significant improvement after surgery in all four areas. Organic manifestations and psychosocial problems had higher average improvements, as did some aspects of the neurovegetative system and difficulties in undertaking daily activities. There were no reports of a worsening of symptoms. CONCLUSIONS: Surgery resolved the hyperthyroidism in 100 % of cases, and was associated with a quality of life improvement of about 70 % in the patients. Surgery can therefore provide an immediate and effective resolution of Graves' disease, with benefits in health-related quality of life.

Total thyroidectomy performed with the Starion vessel sealing system versus the conventional technique: a prospective randomized trial.

Meticulous dissection and accurate hemostasis are required in thyroid surgery. The authors recently performed a number of thyroidectomies using a new device that combines heat and pressure for sealing and cutting tissue. A prospective randomized trial was conducted on 98 patients subjected to total thyroidectomy for benign disease: 49 patients (group A) with the Starion tissue welding system and 49 (group B) with the clamp-and-tie technique. The 2 groups were comparable in mean age, gender, thyroidal volume (20-60 mL), incision length (<35 mm), and pathology. The authors evaluated operative time, postoperative serum calcemia, dosage and length of postoperative calcium and vitamin D treatment, drainage volume, hospital stay, and complications. Student's t test was used for quantitative variables; for categorical variables, the chi(2) test or Fisher's exact test, as appropriate, was used. The mean operative time was 53.8 +/- 6.1 minutes in group A and 63.2 +/- 8 minutes in group B (P < .0001). The difference in terms of postoperative calcemia was significant (group A: 8.35 +/- 0.39 mg/dL; group B: 8.08 +/- 0.39 mg/dL; P < .001). The duration of postoperative treatment with calcium and vitamin D was significantly different (group A: 4 days; group B: 5 days; P < .039). No significant difference in terms of postoperative complications was found. The new system reduced operative time and the duration of postoperative hypocalcemia, and there was minimal tissue necrosis and thermal spread. The reduction in duration of postoperative calcium and vitamin D treatment is also an indication of improvement in quality of the treatment.
