Early diagnosis of this disease is essential to provide effective preventive and therapeutic measures. This process can be used by a computer-aided methodology to improve accuracy. In this study, a new and optimal method has been utilized for the diagnosis of COVID-19. Here, a method based on fuzzy C-ordered means (FCOM) along with an improved version of the enhanced capsule network (ECN) has been proposed for this purpose. The proposed ECN method is improved based on mayfly optimization (MFO) algorithm. The suggested technique is then implemented on the chest X-ray COVID-19 images from publicly available datasets. Simulation results are assessed by considering a comparison with some state-of-the-art methods, including FOMPA, MID, and 4S-DT. The results show that the proposed method with 97.08% accuracy and 97.29% precision provides the highest accuracy and reliability compared with the other studied methods. Moreover, the results show ...

The symptoms of this disease are spreading rapidly and affect almost all systems of the body. In addition to the common symptoms of the virus, numerous reports of rare symptoms of the virus have also been published. These atypical presentations can result in difficulty in diagnosing the disease. The aim of this work is to summarize “uncommon atypical presentations”, which have not received enough attention in descriptions of the disease presentation to date and the authors specifically discuss the important uncommon atypical presentations of COVID-19.

Objectives: This clinical trial aimed to compare short-term and long-term benefits of peritoneal closure with non-closure in an academic medical center. Methods: In this double-blinded two-arm parallel-group randomized trial, 124 patients undergoing laparotomy with midline incision were assessed from March 2019 to September 2019 at Imam Hossein Medical Center, Tehran, Iran. We used the Rand function of the Excel software to randomly assign 62 patients to the peritoneal closure group and 62 patients to the non-closure group. The patients were evaluated for short-term complications including wound-related fever, infection, need for analgesics, pain in the first 2, 6, 24, and 48 hours postoperatively according to the Visual Analogue scale (VAS), duration of hospitalization, as well as long-term complications including incisional hernia and...

Its clinical symptoms are heterogenous and depend on the location and size of the tumor. Inflammatory fibroid polyps are one of the rare benign conditions leading to intestinal intussusception in adults.Case presentation: A 76-year-old woman presented to the emergency department with acute abdominal pain, vomiting, nausea and failure in defecation and gas passing. Physical examination revealed abdominal distension. Abdominal X-ray showed dilated small bowel segments with air-fluid levels. Operative finding was an ileo-ileal intussusception due to a mass lesion at 40 cm proximal to the cecum. Intussusception was spontaneously reduced during exploration and a wedge resection was performed for the affected bowel segment. Histopathologic examination showed the mass to be an inflammatory fibroid polyp. About 4 days after the operation, the pati...

Diagnosis before surgery has always been a problem. One of the symptoms in dealing with patients with suspected appendicitis is dry lips. Therefore, in this study, an attempt was made to investigate the relationship of this sign with appendicitis.Methods: This cross-sectional study was conducted in a one year period. All the patients between 18 and 65 years of age with complaints of abdominal pain were included into the study. Possible diagnosis was appendicitis based on history, clinical examinations, and laboratory tests. Pathological results were recorded. Collected data were analyzed by descriptive statistics using SPSS-16 software. Results: In this study, 125 patients with preoperative diagnosis of appendicitis were evaluated. Mean age was 27±2 years and 65% (n=81) were male and 35% (n=44) were female. Final diagnosis based on pathologic examination revealed that 88.8% (n=111) were appendi...

Other symptoms depend on age and the type of tumor. The tumor is usually asymptomatic if secrets androgens can cause precocious puberty in young children. If the tumor secretes estrogens, it can cause rarely gynecomastia in young boys.Case presentationHere we are reporting pure LCTs in a ten-year-old boy presented with gynecomastia. His height and weight were in the normal range. Differential diagnosis of large cell calcifying Sertoli cell or Leydig cell tumor, teratomas and revealed the normal size and echogenicity of both epididymis confirmed the Leydig cell tumor.ConclusionsDue to the extremely variable clinical presentation tumor especially children and the importance of maintaining the fertility in this group and increased incidence of mali...

The application of ultrasound-guided placement of permanent hemodialysis catheters is highly recommended by the new guidelines because of its advantages over the traditional blind methods.Methods: In this prospective study, the samples comprised patients (N = 80) referred to a vascular surgery clinic by their nephrologist or elective vascular surgery consultations and asking for the placement of permanent hemodialysis catheters in Imam Hossain Hospital (A referral hospital complex center in, Tehran, Iran) during 2014 to 2015. The patients were randomly divided into two groups (n = 40); one of the groups underwent the placement of catheters with the guidance of Doppler ultrasound and the other with the traditional blind method. Then, the data were analyzed by SPSS v.21 software.Results: There was statistically significant fewer attempt...

However, arteriovenous fistula dysfunction is a major clinical issue. The most common cause of arteriovenous fistula failure is intimal hyperplasia. In this study, we have investigated the effect of N-acetylcysteine on neo-intimal hyperplasia after arteriovenous fistula creation in rats. Methods: This study was conducted in 24 rats which were randomly divided into two groups: control and N-acetylcysteine groups. An end-to-side anastomosis was made between the femoral artery and vein. The control group received distilled water intraperitoneally while the animals in N-acetylcysteine group received 300 mg/kg/day of N-acetylcysteine via the same route. After 28 days, the thickness of intima and media was measured using hematoxylin and eosin. Results: There was no significant difference between the two groups regarding age ( p = 0.6) and weight ( p = 0.1). The mean intima thickness in N-a...

Background: According to previous studies, it is recommended that common bile duct investigation should be done in order to rule out choledocholithiasis in all patients with symptomatic cholelithiasis. IOC is an invasive procedure with probable complications, it would seem that MRCP could replace the direct cholangiography. Patients and methods: In a diagnostic clinical trial, Fifty-nine patients with symptomatic biliary stones or cholecystitis were recruited in this study. The included patients had normal size biliary ducts in sonography but high serum alkaline phosphatase level. Preoperative MRCP and IOC were performed for the patients and the obtained results were analyzed and compared. Results: The positive predictive value for IOC was 88% and for MRCP was 43%. The diagnostic accuracy of IOC and MRCP were 98% and 85% respectively, suggesting that IOC is much more diagnostically accurate. There were no significant difference in specificity and sensitivity of these two methods. Conclusion: According to the results, we can conclude that MRCP may not obviate the need for IOC. The suggestion for routine use of MRCP instead of IOC and as a substitution of that procedure needs further investigations on more patients.

The aim of this study was to analyze the long-term outcome of surgical treatment of patients with splenic echinococcosis comparing spleen-preserving surgery with splenectomy. Materials and Methods: During a period of 10 years (1996-2006), 20 patients with splenic echinococcosis entered our study as test and control groups. In our series the spleen was the only organ involved. Splenectomy was performed in the control group and spleen preserving drainage of cyst in test group. Results: There was no significant difference between the splenectomy and spleen-preserving groups concerning median hospital stay, postoperative complication rate and recurrence. (p<0.5) The median follow-up in 15 patients was 52 (range 6-300) months. Conclusion: In the present series it was possible to preserve the spleen affected by hydatid cyst without significant increase of recurrent echinococc...

Zielsetzung der folgenden Untersuchung war es, autologe Vena saphena magna mit PTFE als Gefäßersatzmaterial bei Oberschenkelshunts zu vergleichen. METHODIK: 70 Patienten wurden im Rahmen einer prospektiv randomisierten Studie in 2 Gruppen untersucht. In beiden Gruppen wurden die Oberschenkelshunts in Schleifenkonfiguration angelegt. In der einen Gruppe wurde autologe Vena saphena magna, in der anderen Gruppe PTFE als Gefäßersatzmaterial verwendet. Im Rahmen des Follow-up wurden in definierten Abständen die Shuntfunktion mittels Dopplersonographie und das Auftreten von Komplikationen nachuntersucht. ERGEBNISSE: In Bezug auf die Shuntfunktion, dem Auftreten von postoperativen Shuntthrombosen und die Durchflussraten konnte kein statistisch signifikanter Unterschied zwischen den beiden Gruppen festgestellt werden (p p < 0,05). SCHLUSSFOLGERUNGEN: Zusammenfassend ist die autologe Vena Saphena magna, aufgrund der signifikant niedrigeren Infektionsrate, eine gute Alternative zu PTFE als Gefäßersatzmaterial für Oberschenkelshunts.
