Teacher Emotions in Primary and Secondary Education: Effects of Self-Efficacy and Collective-Efficacy, and Problem-Solving Appraisal as a Moderating Mechanism  [PDF]
Georgia Stephanou, Anastasia Oikonomou
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.94053
Abstract: This study aimed to examine: 1) teachers’ self-reported emotions experienced at school, problem-solving appraisal, self-efficacy and school collective-efficacy; 2) the effects of self-efficacy on the formulation of collective-efficacy and problem-solving appraisal, and on the impact of problem-solving appraisal on collective-efficacy; 3) the influential role of efficacy beliefs, problem-solving appraisal and their inter-effects in the emotions; and 4) the effect of teaching level (primary/secondary school) in the examined concepts. The sample consists of 256 primary and secondary school teachers, 92 men and 164 women, who came from various Greek state schools. Data were collected at the middle of a school year, and they were analyzed between and within groups across all constructs. The results revealed: 1) teachers experienced positive emotions from moderate to high intensity, and negative emotions from low to high intensity, particularly context-, task- and self-related; 2) a moderate to high sense of both efficacy beliefs and problem-solving appraisal (except for personal control that was low); 3) while problem-solving appraisal influenced collective-efficacy, its effect was to a significant extent mediated by self-efficacy; 4) self-efficacy, problem-solving appraisal and collective-efficacy had complimentary impact on the emotions, with self-efficacy being the most powerful formulator of most of them; and 5) the primary school teachers, compared to secondary school teachers, felt more intense positive emotions, had a stronger sense of school collective-efficacy and reported lower impulsive and personal control in problem-solving. The findings are discussed with respect to their practical applications and future research.

Petros Zezos,Georgios Kouklakis,Anastasia Oikonomou,Michail Pitiakoudis,Constantinos Simopoulos
Case Reports in Medicine , 2010, DOI: 10.1155/2010/418769
Abstract: Proximal Crohn's disease, involving the esophagus, the stomach, the duodenum, and the proximal jejunum, is uncommon. Treatment for proximal Crohn's disease is based on data derived from case series than from controlled trials. We present a case of Crohn's colitis with concomitant proximal esophagogastroduodenal involvement treated with conventional treatment plus swallowed aerosolized budesonide as a novel adjuvant topical treatment for the esophageal disease, and we review the treatment options for proximal Crohn's disease.

Case Reports in Radiology , 2013, DOI: 10.1155/2013/869793
Abstract: Lung cancer associated with neurofibromatosis type I is considered very rare, and only a few case reports have been described in the literature. There is some evidence that a genetic linkage between neurofibromatosis and carcinogenesis in the lung may exist. We present a 42-year-old female, lifetime nonsmoker with a known history of neurofibromatosis type I, free of respiratory symptoms, who underwent a low-dose HRCT of the lungs to investigate any occult interstitial lung changes. A solitary ill-defined nodule of a ground-glass opacity was detected incidentally in the middle lobe with no associated lymphadenopathy or metastatic disease. Several thin-walled lung cysts were also seen in the lower lobes. Histological analysis of the nodule after middle lobectomy revealed well-differentiated adenocarcinoma. The patient did not receive systemic chemotherapy or radiotherapy. She was free of disease on 18-month followup. 1. Case Presentation A 42-year-old female, lifetime nonsmoker with a known history of neurofibromatosis type I (NF-1) presented to the Outpatient Neurology Clinic for a regular followup. Physical examination revealed multiple café-au-lait spots and cutaneous neurofibromas of variable size throughout her body (Figure 1). She also suffered from vitiligo since the age of 20 years old. Her neurologic examination was unremarkable, and she was free of respiratory symptoms. She reported no history of environmental or occupational exposure to other potential carcinogens for lung cancer. However, as part of her thorough followup, she underwent a low-dose HRCT of the lungs to investigate any occult interstitial lung abnormalities and presence of lung cysts that have been described in neurofibromatosis patients [1]. Figure 1: Multiple café-au-lait spots and cutaneous neurofibromas of variable size were noted throughout the patient’s body. HRCT of the lungs detected an incidental ill-defined solitary pulmonary nodule 1.4?cm in diameter, exhibiting a ground-glass opacity and air alveologram (Figure 2). No other lung nodules or areas of consolidation were seen in any other lobes. Several small thin-walled lung cysts were also detected in both the upper and the middle lobes, some of which had a subpleural location. No other interstitial lung changes were seen. There were no enlarged mediastinal or hilar lymph nodes. Figure 2: HRCT at the level of the middle lobe shows a 1.4?cm ill-defined nodule of a ground-glass opacity in the right middle lobe demonstrating air alveologram. Differential diagnosis of the solitary ground-glass nodule included primary lung
Total Splenectomy due to an Unexpected “Complication” after Successful Extended Laparoscopic Partial Decapsulation of a Giant Epidermoid Splenic Cyst: A Case Report
Michail Pitiakoudis,Petros Zezos,Anastasia Oikonomou,Prodromos Laftsidis,Georgios Kouklakis,Constantinos Simopoulos
Case Reports in Medicine , 2011, DOI: 10.1155/2011/318208
Abstract: Splenic cysts are rare entities and are classified as true cysts or pseudocysts based on the presence of an epithelial lining. Congenital nonparasitic true cysts can be epidermoid, dermoid, or endodermoid, present at a young age, and are commonly located in the upper pole of the spleen. Surgical treatment is recommended for symptomatic, large (more than 5 cm), or complicated cysts. Depending on cyst number, location, relation to hilus, and the major splenic vessels, the surgical options include aspiration, marsupialization, cystectomy, partial cystectomy (decapsulation), and partial or complete splenectomy. Laparoscopic techniques have now become the standard approach for many conditions, including the splenic cysts, with emphasis on the spleen-preserving minimally invasive operations. We present the successful extended partial laparoscopic decapsulation of a giant epidermoid splenic cyst in a young female patient that, although asymptomatic, was unfortunately followed by complete splenectomy five days later due to a misinterpreted abdominal CT suggesting splenic postoperative ischemia.

Diagnostic and Therapeutic Endoscopy , 2011, DOI: 10.1155/2011/384143
Abstract: The over-the-scope-clip (OTSC; Ovesco Endoscopy GmbH, Tuebingen, Germany) system is a newly designed method for the mechanical compression of large areas in the gastrointestinal tract. So far, indications for OTSC application are hemostasis of primary or postinterventional bleeding, closure of iatrogenic full-thickness or covered perforations. Recently closure of gastrointestinal tract fistulas using this device has been described. A 44-year-old man developed a gastrocutaneous fistula after surgical treatment for a perforated gastric ulcer. We describe the successful endoscopic closure of the fistula using the OTSC system. The patient's clinical followup was uneventful. Fistula closure was successfully implemented as it was documented by imaging and endoscopic examinations performed on the 2nd day and 6th week after the application of the clip. Endoscopic application of the OTSC device was safe and effective for the treatment of a gastrocutaneous fistula. 1. Introduction The over-the-scope-clip (OTSC) system (Ovesco Endoscopy GmbH, Tuebingen, Germany) is a newly designed method for the mechanical compression of large areas in the gastrointestinal tract. So far, indications for OTSC application are hemostasis primary or postinterventional bleeding and closure of iatrogenic full-thickness or covered perforations during endoscopic mucosal resection or after natural orifice transluminal endoscopic surgery procedures (NOTES) [1]. We report the successful treatment of a gastrocutaneous fistula with closure of the gastric orifice using the OTSC system without postprocedure complications. 2. Case Presentation A 44-year-old man, who had been having a history of recurrent abdominal pain, attended the emergency services with peritonitis. Upright chest X-ray demonstrated free subdiaphragmatic air bilaterally (Figure 1). An emergent laparotomy was performed and a perforated pyloric ulcer was found which was treated with simple surgical sutures and omental patches. Figure 1: Upright posteroanterior chest radiograph: there is free subdiaphragmatic air bilaterally that is more clearly noted on the left side (white arrows). A few days later the patient displayed a septic course with persistent fever and leukocytosis. An abdominal CT scanning revealed an abscess in the left subphrenic space and in the space of Douglas. A new surgical intervention was undertaken and peritoneal drainage was reestablished in the areas with the abscesses. The immediate postoperative period was uneventful with the exception of a persistent draining of gastric contents by the abdominal drains
