Case report Ileal diverticulitis with covered perforation complicated by pulmonary embolism - case report.

Diverticulitis of the ileum is an inflammatory complication of diverticulosis. It is an uncommon cause of acute abdomen that can have a very serious course, leading, for example, to intestinal perforation or bleeding. Imaging findings are very often negative and the true cause of the condition is only revealed peroperatively. In this case report, we present a case of perforated ileal diverticulitis in a patient with bilateral pulmonary embolism. This was the main reason for conservative management in the first period of time. After resolution of the pulmonary embolism, resection of the affected bowel segment was performed at the time of the next attack.

Appendiceal mucocele - a radiologists view.

Appendiceal mucocele is an obstructive dilatation of the appendix, which results from the filling of its lumen with mucus. This is a rare condition that is asymptomatic in half of the patients. Its severity depends on the cause of appendiceal dilatation. In a small percentage of cases, the dilated appendix ruptures, leading to the development of serious complication; this is termed as pseudomyxoma peritonei. Due to the possibility of malignant etiology of the mucocele, surgical resection remains an essential part of the treatment.

Acute abdomen in patients with Crohns disease case reports.

INTRODUCTION: Crohns disease (CD) as a chronic inflammatory disease can affect the entire digestive tract and therefore involves a wide range of symptoms and health problems. It often mimics other diseases of the digestive tract. In the case of acute abdomen in a patient with CD, it is necessary to approach it individually in cooperation with a gastroenterologist in order to reduce the extent of resection and to ensure fewer resections. CASE REPORTS: In our two case reports, we present patients with bowel obstruction and inflammatory acute abdomen. The first patient benefits from conservative treatment despite the presence of a bowel obstruction (resulting from inflammation) before subsequent surgical treatment. It is a relatively common acute complication of CD. The second patient, despite her ongoing pregnancy and the impossibility of using appropriate imaging techniques in the follow-up treatment, with regard to her clinical condition, requires an urgent surgical solution due to a fairly rare perforation to abdominal cavity. Key words: Crohns disease - surgery - acute abdomen - bowel obstruction - peritonitis.

Acute hiatal hernias.

INTRODUCTION: In surgical practice, hiatal hernias are often related to gastro esophageal reflux disease treatment in which continuous proton pump inhibitor administration is very successful. In large hiatal hernias, life threatening complications may occur. However, planned surgical repair of hiatal hernias is associated with very good functional outcomes with a low risk of postoperative complications. The incidence of large hiatal hernias grows with increasing age of the patient. In geriatric patients, internal comorbidities are also more frequent, including serious conditions. In these patients, one may hesitate whether to perform surgery with regard to the possible risk of postoperative complications. Conservative treatment of hiatal hernias is associated with a higher risk of stomach volvulus or severe bleeding as the most frequent complications. METHODS: We performed a retrospective study of patients operated on for a large hiatal hernia at the Department of Surgery, University Hospital Brno, between 2010 and 2016 (86 months). The patients were divided into 2 groups depending on the type of operation: acute (A) and elective (B). We evaluated demographic data, the nature of preoperative symptoms, type of surgery and postoperative complications. RESULTS: 120 patients were operated on for large hiatal hernia in this period of time. Group A involved 22 operated patients, group B 98 patients. There was a significantly higher number of laparotomies in the acute patient group compared to the elective group B (72.7 % vs. 23.5%, p.

The prevalence of melanocytic naevi among schoolchildren in South Hungary.

BACKGROUND: Malignant melanoma is an increasing public health problem worldwide; accordingly, identification of the constitutional and environmental factors which contribute to the development of the disease, and hence identification of the individuals at high risk of melanoma, is an indispensable step in all primary prevention efforts. OBJECTIVES: This paper aims to assess the prevalence of different pigmented lesions among schoolchildren and to investigate their relationship with phenotypic pigmentary characteristics, sun exposure and other factors. PATIENTS/METHODS: A cross-sectional study was performed in two secondary schools in Szeged, Hungary. A total of 1320 schoolchildren, aged 14 to 18 years, underwent a whole-body skin examination. A standardized questionnaire was used to collect data on phenotypic, sun exposure and other variables. RESULTS: One to 10 common melanocytic naevi were found in 27% of the participants, and the naevus numbers were in the range of 10-100 in 67%; 5.4% of them had more than 100 common melanocytic naevi. The prevalence of clinically atypical naevi was 24.3%. Statistically significant associations were found between the number of pigmented lesions and gender, hair colour, eye colour, skin phototype, a history of severe painful sunburns and a family history of a large number of melanocytic naevi. CONCLUSION: Our study population displayed a markedly high prevalence of clinically atypical melanocytic naevi. Moreover, a considerable proportion of the investigated individuals had multiple common melanocytic naevi. Since the presence of a large number of melanocytic naevi is a strong predictor for future melanoma development, health educational programmes on melanoma prevention should be aimed at young age groups.

Small bowel ultrasound in patients with celiac disease. Retrospective study.

OBJECTIVE: Celiac disease (CD) is a common, lifelong disease with small bowel malabsorption based on genetically conditioned gluten intolerance. The clinical manifestation could be very heterogeneous. The proof of celiac disease is now based mainly on clinical and laboratory (antibodies and enterobiopsy) signs, which are in some cases problematic and inconvenient. MATERIALS AND METHODS: In our study we have examined 250 patients with suspection or with proven celiac disease and we evaluated specific ultrasound small bowel changes in this group. In the next step, we chose 59 patients with laboratory proved celiac disease and we statistically compared ultrasound, other laboratory and clinical findings in different forms and stages of the disease. RESULTS: Specific small bowel pathologies in patients with celiac disease (like changes of intestinal villi in different parts of small bowel, abnormal peristalsis and mesenterial lymphadenopathy) can be well visualized by ultrasound and in combination with clinical and laboratory signs ultrasound examination could have an important role in screening, determination of diagnosis and monitoring of patients with different forms of celiac disease.
