Total severity score and age predict long-term hospitalization in COVID-19 pneumonia.

Background: Severe COVID-19 pneumonia implies increased oxygen demands and length of hospitalization (LOS). We aimed to assess a possible correlation between LOS and COVID-19 patients' clinical laboratory data of admission, including the total severity score (TSS) from chest computed tomography (CT).

Methods: Data were assessed retrospectively at the General Hospital "Agios Pavlos" in Greece.

Improving Guideline Adherence in Urology.

Context: Clinical practice guidelines (CPGs) distil an evidence base into recommendations. CPG adherence is associated with better patient outcomes. However, preparation and dissemination of CPGs are a costly task involving multiple skilled personnel.

Thrombosed Aneurysm of Superficial Epigastric Vein Simulating Inguinal Hernia: Report of Two Cases.

Aim: Presentation of two cases of superficial epigastric vein aneurysm simulating inguinal hernia. To our knowledge, only one other case is reported in the literature. .

Adrenal Cortical Rests in the Fallopian Tube: Report of a Case and Review of the Literature.

We report an extremely unusual finding discovered incidentally during a routine pathologic evaluation of a fallopian tube, surgically removed on the grounds of ectopic pregnancy. We came across a minute yellowish nodule situated within the wall of the salpinx, which corresponded to ectopic adrenal cortex, as verified by microscopical examination, and coexisted with salpingitis isthmica nodosa. A research of the available English literature on this subject confirmed the rareness of the entity we encountered.

Alzheimer's disease and gastrointestinal microbiota; impact of infection involvement.

Alzheimer disease (AD) is a leading cause of global burden with great impact on societies. Although research is working intensively on promising therapy, the problem remains up-to-date. Among the various proposed hypotheses regarding causality and therapy, emerging evidence supports the hypothesis that gastrointestinal microbiota through the so-called 'gut-brain axis' interacts with immune system and brain and shape the balance between homeostasis and disease; the involvement of gastrointestinal microbiota in the pathophysiology of AD is less defined, even though the role of 'gut-brain axis' has been well verified for other neurodegenerative conditions.

Hookworms in Emergency Department: The ＂Vampire＂ Within.

Hookworms infection is a soil-transmitted helminthic disease particularly endemic in developing counties of tropical regions. It is attributed mainly to two human pathogens nematodes namely Necator americanus and Ancylostoma duodenale. Although the disease has been characterized as "neglected" is very diffi cult to be eliminated and the economic consequences are great.

National registry of hemoglobinopathies in Greece: updated demographics, current trends in affected births, and causes of mortality.

National registries constitute an invaluable source of information and contribute to the improvement of hemoglobinopathy management. Herein, we present the second updated report of the National Registry for Haemoglobinopathies in Greece (NRHG) and critically discuss the time trends in demographics, affected births, and causes of mortality. Thirty-eight Greek hemoglobinopathy units reported data from diagnosis to the last follow-up or death by retrospectively completing an electronic form.

Abdominal rectus muscle pyomyositis: Report of a case and review of the literature.

Pyomyositis is an uncommon primary bacterial infection of skeletal muscles, usually caused by Staphylococcus aureus. Predisposing factors for pyomyositis include immunodeficiency, trauma, injection drug use, concurrent infection and malnutrition. The diagnosis, staging of the disease and differential diagnosis are established by ultrasound, CT and MRI.

Left Brachiocephalic Vein Stenosis due to the Insertion of a Temporal Right Subclavian Hemodialysis Catheter.

Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma.

Fournier's Gangrene: Lessons Learned from Multimodal and Multidisciplinary Management of Perineal Necrotizing Fasciitis.

Background: Fournier's gangrene (FG) is a rapidly evolving necrotizing fasciitis of the perineum and the genital area, the scrotum as it most commonly affects man in the vast majority of cases. It is polymicrobial in origin, due to the synergistic action of anaerobes and aerobes and has a very high mortality. There are many predisposing factors including diabetes mellitus, alcoholism, immunosuppression, renal, and hepatic disease.

Giant extra gastrointestinal stromal tumor of lesser omentum obscuring the diagnosis of a choloperitoneum.

Introduction: Herein we present an extremely rare case of a giant extra gastrointestinal stromal tumor (EGIST) of the lesser omentum obscuring the diagnosis of a choloperitoneum.

Presentation Of Case: A 79 years old female was admitted to our hospital with symptoms of vomiting and epigastric pain. Abdominal computer tomography revealed a sizable formation that was diagnosed as a tumor of the pancreas.

Hemodialysis catheter malposition induced by a brachiocephalic vein stenosed stent.

Malposition of a central venous hemodialysis catheter, mainly due to central vein stenosis or thrombosis, is not an uncommon complication. Herein, we present a rare cause of a left external jugular vein hemodialysis catheter, malpositioned into the ipsilateral internal jugular-subclavian venous route, due to a stenosed stent that has been placed into the ipsilateral brachiocephalic vein.

Unusual malpositioning of hemodialysis catheter into the hepatic veins.

Malpositioning of long-term hemodialysis catheter is a known complication that may lead to a gradual decline in blood flow. We report two rare catheter malpositions in the hepatic veins in two patients with end-stage renal disease in whom a dialysis catheter was inserted through the left external jugular vein and the right external jugular vein. Because of gradual reduction of catheters' blood flow, an angiography was performed, which confirmed catheters' tip positioning into the hepatic veins.

Insertion of permanent hemodialysis catheters through the great saphenous vein.

Introduction: In patients with end stage renal disease when there is inability for the creation of a direct arterio-venous fistula or by using a graft, the insertion of a permanent hemodialysis catheter in a central vein ensures the conduction of hemodialysis. We present a technique of placing a permanent catheter in the inferior vena cava through the great saphenous vein without the use of a guide wire.

Patients-methods: Over the study period, 12 hemodialyzed patients, with a mean age of 73 years, were referred for placement of a dialysis catheter through the great saphenous veins.

A case of extraskeletal Ewing sarcoma originating from the visceral pleura.

Extra skeletal Ewing Sarcoma (EES) is a rare entity which predominantly occurs in adolescents and young adults. It usually arises from the soft tissues of the trunk or the extremities. We present a case of EES arising from the left visceral pleura in a 21 year old female patient who presented to the emergency room of our institution with fever, productive cough and sternal pain radiating to the back for the last 3 days.

Desmoid tumor of the abdominal wall: a case report.

Case Presentation: The case of a desmoid tumor of the anterior abdominal wall in a 40-year-old Caucasian man with no relevant family history is presented, describing its appearance on computed tomography and ultrasonography.

Benign multicystic peritoneal mesothelioma: a case report.

Introduction: We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings.

Case Presentation: A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen.

Imperforate anus associated with atresia of the transverse colon: a case report.

We describe here a rare case of association of imperforate anus with transverse colon atresia in a male neonate. Preoperative X-ray studies demonstrated: a) a distended loop in the epigastrium with fluid levels on plain A/P upright radiography, b) absence of pelvic intestinal gas on the invertogram 16 hours later. A three-stage operative approach was undertaken comprising resection of the atretic loop and colostomy, posterior sagittal anorectoplasty a few months later, and finally closure of the colostomy.

Haemoglobin O Arab in the Pomak population of Thrace.

A 21 year old woman from Thrace with clinical and laboratory findings of mild hemolysis, was found to be homozygous for haemoglobin O Arab. Blood samples from 15 members of her family and from 42 inhabitants of her village were examined for the presence of Hb O Arab. A high incidence of this variant allele was also detected among the patient's family members as well as in other inhabitants of the village (p = 0.

Angiogenesis in invasive breast carcinoma: is it associated with parameters of prognostic significance?

Recent experimental and clinical studies suggest that tumour-induced angiogenesis may be an important step in the evolution of malignant tumours, and may be related to prognosis. In our study we examined 42 cases of breast carcinoma (mean age: 56.76 +/- 13.
