Are Football Players More Prone to Muscle Injury after COVID-19 Infection? The "Italian Injury Study" during the Serie a Championship.

Introduction: Football was the first sport to resume competitions after the coronavirus disease 2019 (COVID-19) lockdown and promptly the hypothesis was raised of a potential relationship between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and musculoskeletal injuries in athletes. This study aimed to confirm the association between SARS-CoV-2 infection and muscle strain injury in a large population of elite football players and to investigate if the COVID-19 severity level could affect the risk of injury.

Methods: A retrospective cohort study involving 15 Italian professional male football teams was performed during the Italian Serie A 2020-2021 season.

Sigmoid intramural hematoma and hemoperitoneum: an early severe complication after stapled hemorrhoidopexy.

Stapled hemorrhoidopexy is a widely used surgical technique for treating hemorrhoids, although severe complications have been reported. The authors report a rare case of extensive ascending intramural hematoma of the sigmoid colon complicating stapled hemorrhoidopexy, with perforation and hemoperitoneum. Diagnosis was established at CT scan and treatment consisted of drainage, suturing, and diverting colostomy.

[Laparoscopic appendicectomy: an 8-year clinical experience].

Background: For more than a century, open appendectomy through a laparotomy has been the golden standard for the surgical removal of the appendix. Nowadays, many surgeons question the utility of laparoscopic surgery to perform appendectomies because it is commonly stated that the appendix can be removed through a small surgical incision carrying a minimal surgical trauma to the patient. Although open appendectomy is really safe, on the other hand it carries a considerable risk of postoperative complications, is associated with postoperative pain and affects patient s normal activity.

[Intestinal infarction. Retrospective clinical study].

Acute mesenteric ischaemia is the result of inadequate blood flow to all or part of the small intestine and the right half of the colon. Irrespective of the cause of the ischaemic insult, the end results are similar, namely, a spectrum of bowel injury ranging from completely reversible alterations of bowel function to transmural haemorrhagic necrosis of the intestinal wall. Depending on the degree of ischaemia and the length of bowel involved, a wide variety of clinical presentations are observed.

[Therapeutic strategy in symptomatic diverticular disease of the colon].

Diverticular disease of the colon has been recorded with increasing frequency and approximately 25-30% of symptomatic patients require surgery for complications. Controversy still surrounds the best operative approach for the management of diverticular disease, particularly when it presents with complications. The three-stage operation has, for the most part, been abandoned because of its unacceptably high morbidity and mortality rates.

[An intramural hematoma of the duodenum].

Intramural hematoma of the duodenum is a rare event which is usually associated with trauma. Because of the rarity of this problem, there has been little conformity of opinions as to diagnosis and treatment of this disease. The authors report on a case of intramural hematoma of the duodenum post-traumatically occurred in a young woman.

[Adenocarcinoma of the duodenojejunal flexure. A report of 2 clinical cases and a review of the literature].

The authors report two cases of adenocarcinoma of the duodenojejunal angle and remark the rarity of this pathology, the difficulty of making diagnosis peculiar to neoplasm of the small intestine and the difficulty of treatment peculiar to tumours of the duodenum. According to the literature the diagnosis was determined through X-ray films, after traditional endoscopy was inadequate. Surgical treatment is radical, with extensive exeresis procedures (unless the mesenteric upper vessels are infiltrated) since the prognosis of this tumours is good.

Pre-operative angiography in gastric cancer surgery with extended lymphadenectomy.

Background/aims: The value of pre-operative angiographic evaluation in patients undergoing gastric cancer surgery with extended lymphadenectomy was assessed in a prospective study comparing exposed and unexposed groups of patients.

Methodology: During the period from July 1991 to October 1997, 76 patients (Group A--exposed) were pre-operatively submitted to a digital subtraction angiography (DSA) after informed consent. Concurrently, 94 patients (Group B--unexposed) were included as an unexposed reference group.

Juvenile polyposis: case report and assessment of the neoplastic risk in 271 patients reported in the literature.

A case of juvenile polyposis is reported and 271 cases are collected from the literature. The risk for neoplasia is analyzed and the endoscopic or surgical therapy is discussed. The authors conclude that juvenile polyposis should be considered as a challenge to the surgeon with regard to familial adenomatous syndromes, and strongly recommend a close follow-up of patients with juvenile polyposis.

[Juvenile polyposis coli associated with hereditary spherocytosis].

The first case of colorectal juvenile polyposis associated with hereditary spherocytosis is reported. Symptoms, diagnosis and therapy of juvenile polyposis are described along with the associated syndromes reported in the literature. The scientific and clinical consequences of this association are discussed.

[Biliary lithiasis in childhood. A spectrum of diseases with different clinical significance during fetal life, childhood and adolescence].

On the basis of a research on fetal cholelithiasis, a review on the various form of cholelithiasis in pediatric age has been carried out. These include, in addition to fetal cholelithiasis, lithiasis in the first year of life and lithiasis in infancy and adolescence. These various expressions of the same pathology differ for incidence, predisposing factors, clinical situation, therapy and follow-up.

[Prospective research on fetal cholelithiasis: incidence, predisposing conditions, echographic diagnosis, and clinical features].

The Authors report a prospective study on fetal cholelithiasis, analyzing its differences with the more widely known cholelithiasis of paediatric age. The study shows that the number of cases diagnosed by ultrasonography is higher than expected (0.39%, 3 cases on 764 pregnancies).

Juvenile polyposis coli and associated anomalies. Review of the literature and report of a case associated with hereditary spherocytosis.

A case of juvenile polyposis associated with hereditary spherocytosis is presented. All the anomalies associated with juvenile polyposis coli reported in the literature are reviewed. The clinical consequences of such a report are discussed along with the different forms of therapy for treating juvenile polyposis coli.

[Fetal biliary lithiasis: ultrasonographic diagnosis and clinical interpretation. Report of 3 cases].

Fetal cholelithiasis was first diagnosed in 1983 and since then there have been only few reports about the presence of gallstones in the fetus. Maternal conditions, fetal or obstetrical predisposing risk factors have been proposed to have a causative role, but the pathogenesis of fetal gallstones remains unknown. Clinical sequelae of fetal gallstones are poorly understood as well as the role of fetal cholelithiasis in predisposing the adult to gallstones.

[A case of gastric hemangiopericytoma].

The authors report a case of gastric hemangiopericytoma. This tumor, histogenetically derived from pericytes, has been detected in any tissue or structure. According to the review of the literature, the hemangiopericytoma of the stomach occurred very uncommonly, being published only 29 cases.

[Original excluding cecostomy procedure for the prevention of colorectal anastomotic dehiscence].

The authors report the results of an original technique of cecostomy performed on 30 patients as an alternative to temporary colostomy. Colorectal anastomotic leakage following surgery represents the main indication to this procedure. This original technique seems to be safer, simpler and more effective than a temporary colostomy.

Arterial vasculature of the stomach and oncologic gastrectomies.

Preoperative knowledge of the gastric arterial blood-supply with special regard to anatomic anomalies is desirable for a correct surgical approach to this viscus and for the reduction of intra- and postoperative complication rates. The authors report their experience with the use of preoperative digital angiography in the evaluation of 46 consecutive patients undergoing gastric cancer surgery. Twenty of these (43.

The role and timing of surgery in the treatment of pseudomembranous colitis. A case complicated by toxic megacolon.

The authors describe a particularly serious case of pseudomembranous colitis due to Clostridium difficile that was complicated by toxic megacolon. It was resolved by surgical intervention, and the reasons why subtotal colectomy is preferable to simple ileostomy are discussed.

[Long-term results of surgical treatment of early cancers of the stomach].

The postoperative course of 172 patients with early gastric cancer operated between 1974 and 1987 was reviewed with a median follow-up of 7 years. The survival probability at the end of 1989 was 0.916 (excluding operative mortality and other causes of death) or 0.

[The surgical treatment of hepatic echinococcosis and of its biliary complications].

The authors report the experience of 47 patients submitted to surgery for hepatic hydatidosis. Results from different therapeutic procedures are then compared. Finally, possible biliary complications of the hepatic echinococcosis and their surgical treatment are discussed.

An original reconstructive method after pylorus-preserving pancreatoduodenectomy.

Acute pancreatitis and leakage of pancreaticojejunal anastomosis are the most important causes of operative morbidity and mortality after pancreatoduodenectomy. We have introduced a modified technique for reconstruction that provides a functional exclusion of the pancreatic-jejunostomy in respect of the transit of gastric and biliary secretions. The immediate advantages of this technique are the reduction in the risk of leakage and the possibility of undertaking conservative treatment, in the case that leakage occurs.

[A case of extrarenal angiomyolipoma with intestinal localization].

The Authors present a case of extrarenal angiomyolipoma. The tumor arose from the pericolonic fat of the sigmoid colon and, increasing in size, caused intestinal obstruction by extrinsic lesion. Extrarenal angiomyolipoma is extremely rare and to our knowledge this is the first reported case arising from the colonic wall.

A rare case of splenic hematoma following chronic pancreatitis--the diagnostic and therapeutic procedures.

We describe herein a clinical case in which a subcapsular splenic hematoma complicated chronic relapsing pancreatitis. A pathogenetic mechanism is postulated that explains the subacute insorgence of the liquid collection with the diffusion of proteolytic enzymes between the splenic capsule and parenchyma. Radical therapy, consisting of exeresis of the cystic formation, splenectomy and caudal pancreatectomy, is recommended for this extremely rare complication.
