Background: Previous studies have reported chest radiographic findings of consolidation and ground-glass opacity in patients with swine-origin influenza A (H1N1). However, most of these studies include both hospitalized and outpatients. Purpose: To evaluate initial chest radiographic and CT findings of hospitalized swine flu patients, adults and children, confirmed with a real-time reverse transcriptase polymerase chain reaction (PCR) assay for H1N1 virus. Material and Methods: All PCR-verified swine flu patients admitted to the Department of Emergency Medicine (October 1 to December 15, 2009) at Oulu University Hospital, in Northern Finland, who underwent frontal chest radiography within 24 hours of presentation and who were hospitalized, were included. The radiographs and CT scans were assessed for the presence of pneumonia and characterized by pattern and distribution. The patients' medical records were analyzed for demographics, underlying medical conditions, the admission to the intensive care unit (ICU), initiation of mechanical ventilation or non-invasive ventilation support (NIV) and death. Results: Of 159 H1N1 influenza patients, 135 (85%) underwent chest radiographs at admission; 113 adults and 22 children. Findings of pulmonary infiltrates were detected in 62% (70/113) of adults and 64% (14/22) of children, being bilateral in 67% of adults and 64% of the children. The anatomic location of infiltrates was more often peripheral in adults; 42/70 (60%) vs. 4/14 (29%), P = 0.041, and diffuse among children; 9/14 (64%) vs. 26/70 (37%), P = 0.078. When the ICU and NIV patients were compared to less severe cases, on their chest radiographs four or five lobes were more often affected (65%, 11/17 vs. 34% 23/67, P = 0.029 ). The predominant radiographic findings were consolidation (93% of all patients, 91% of adults and 100% of children) and ground-glass opacity (74% of all, 77% of adults and 57% of children). Pulmonary emboli were detected by CT in 2/9 (22%) patients. Conclusion: The pandemic 2009 swine influenza causes common and widely distributed infiltrates on chest radiographs among hospitalized patients, which are not peculiar to usual respiratory viral infections, and these findings can not be differentiated from usual bacterial pneumonia.

Background: Prophylactic placement of a mesh has been suggested to prevent parastomal hernia, but evidence to support this approach is scarce., Objective: The aim of this study was to evaluate whether laparoscopic placement of a prophylactic, dual-component, intraperitoneal onlay mesh around a colostomy is safe and prevents parastomal hernia formation after laparoscopic abdominoperineal resection., Design: This is a prospective, multicenter, randomized controlled clinical trial., Settings: This study was conducted at 2 university and 3 central Finnish hospitals., Patients: From 2010 to 2013, 83 patients undergoing laparoscopic abdominoperineal resection for rectal cancer were recruited. After withdrawals and exclusions, the outcome of 70 patients, 35 patients in each study group, could be examined., Interventions: In the intervention group, an end colostomy was created with placement of a intraperitoneal, dual-component onlay mesh and compared with a group with a traditional stoma., Main Outcome Measures: The main outcome measures were the incidence of clinically and radiologically detected parastomal hernias and their extent 12 months after surgery. Stoma-related morbidity and the need for surgical repair of parastomal hernia were secondary outcome measures., Results: Parastomal hernia was observed by clinical inspection in 5 intervention patients (14.3%) and in 12 control patients (32.3%; p = 0.049). Surgical repair of parastomal hernia was performed in 1 control patient (3.2%) and in none of the patients in the intervention group. CT detected parastomal hernia in 18 intervention patients (51.4%) and in 17 control patients (53.1%; p = 1.00). The extent of hernias was similar according to European Hernia Society classification (p = 0.41). Colostomy-related morbidity (32.3% vs 14.3%; p = 0.140) did not differ between the study groups., Limitations: The study was limited by its small size and short follow-up time., Conclusions: Prophylactic laparoscopic placement of intraperitoneal onlay mesh does not significantly reduce the overall risk of radiologically detected parastomal hernia after laparoscopic abdominoperineal resection. However, prophylactic mesh repair was associated with significantly lower risk of clinically detected parastomal hernia.

Background: In Finland, the pandemic A(H1N1)v-influenza was experienced in late 2009., Material and Methods: A(H1N1)v-patients hospitalized in Oulu University Hospital were evaluated., Results: Altogether, 159 A(H1N1)v-patients, including 37 children, were hospitalized. Their median age was 35. Eighteen (11 %) patients required admission to ICU; three of them died. As many as 62% of the patients suffered from radiologically confirmed pneumonia. The incidences of hospitalization, ICU care and death were 40,5, 4,6 and 0,8 per 100000, respectively., Conclusions: Despite the low mortality rate, a rather high number of patients required hospitalization. Findings in chest radiography were common and prominent.

Most patients, up to 75-80 percent, with anatomical diverticulosis will remain uncomplicated with a few symptoms. They might benefit of increasing their fruit and vegetable fibre intake and active movement. Advancing age of the Finnish population and decreasing daily consumption of dietary fibre led at the end of 1990' to increasing incidence of diverticle perforations. The annual mortality associated with diverticle perforation is as high as that following hip fracture. It has earlier been recommended that the patients aged under 50 years should be operated after recovery from one acute diverticulitis. However, at present younger patients seem not to be at an increased risk of complications. Elective operation after acute diverticulitis should be made on a case-by-case basis and operations should be restricted to the most symptomatic patients.
