[show abstract][hide abstract] ABSTRACT: Idiopathic intussusception is one of the most common causes of small bowel obstruction in children. In the event of failed radiological reduction, laparotomy remains the treatment of choice. There is still no agreement in pediatric surgery about safety and effectiveness of the use of minimally invasive surgery in this common pediatric condition. By reviewing available data we aimed to establish whether laparoscopy should be the primary technique in the surgical reduction of intussusception.
A systematic review of all publications on the laparoscopic treatment of pediatric intussusception from January 1990 to April 2012 was performed. The following variables were analyzed: age, laparoscopic success rate, reason for conversion, enterotomy rate, operative time, complications, and length of stay (LOS).
Ten retrospective studies treating 276 cases of laparoscopically reduced intussusception were identified. A total of 80 conversions corresponded to a 71.0% laparoscopic success rate. Only one case of intraoperative iatrogenic intestinal perforation was reported (0.4%). Postoperative complications occurred in 8 patients (2.9%), and adhesive small bowel obstruction was reported in 1 case (0.4%). Recurrence rate after laparoscopy was 3.6%. Three of 10 papers compared results between laparoscopic and open reduction of intussusception showing a shorter mean LOS in the former group (4.0 vs. 7.1days, p<0.01).
Laparoscopy is safe and effective in the treatment of pediatric intussusception. Tertiary centers with adequate minimally invasive skills should establish laparoscopy as the primary surgical technique in the treatment of this condition.

[show abstract][hide abstract] ABSTRACT: Diarrhoea is the most frequent health problem among travellers in the tropics. However, data on the spectrum and relevance of enteropathogens in international travellers with and without diarrhoea are limited. Stool samples from 114 cases of diarrhoea in travellers returning from the tropics were collected for microbiological examination and PCR for norovirus genogroups I and II, enteroaggregative Escherichia coli (EAEC), and enterotoxigenic E. coli (ETEC) producing heat-labile toxin (LT) and heat-stable toxin (ST). Travel and laboratory data of cases were compared with those of 56 travellers without diarrhoea. Among cases, EAEC was found in 45% of stool samples, followed by LT-ETEC (20%), ST-ETEC (16%), Blastocystis hominis (15%), Campylobacter jejuni (12%), norovirus (11%), Giardia lamblia (6%), Shigella spp. (6%), and Salmonella spp., Cryptosporidium spp., and Cyclospora cayetanensis (3% each). However, only for EAEC, ST-ETEC, Blastocystis and Campylobacter was the prevalence significantly higher among cases than among controls. Co-infections were common: 61% for cases and 13% for controls. The most common travel destination was Asia (54%), followed by Africa (35%) and Latin America (9%). The highest relative risk for diarrhoea was calculated for travellers to West Africa, East Africa, and South Asia. In this study, EAEC, LT-ETEC and ST-ETEC were detected most frequently in cases of travellers' diarrhoea. Although enteric infections with EAEC, ST-ETEC and Campylobacter often cause diarrhoea, the pathogenetic relevance remains unclear for most of the other enteropathogens, because of significant prevalence rates also being seen in controls without diarrhoea and the high frequency of co-infections.

[show abstract][hide abstract] ABSTRACT: There is a high incidence of diarrhea in traveling populations. Norovirus (NV) infection is a common cause of diarrhea and is associated with 7% of all diarrhea related deaths in the US. However, data on the overall prevalence of NV infection in traveling populations is limited. Furthermore, the prevalence of NV amongst travelers returning to Europe has not been reported. This study determined the prevalence of NV among international travelers returning to Germany from over 50 destinations in and outside Europe.
Stool samples of a total of 104 patients with a recent (< 14 days) history of international travel (55 male, mean age 37 yrs.) were tested for the presence of NV genogroup (GG) I and II infection using a sensitive and well established quantitative RT PCR method. 57 patients experienced diarrhea at the time of presentation at the Department of Infectious Diseases & Tropical Medicine. The remaining 47 patients had no experience of diarrhea or other gastrointestinal symptoms for at least 14 days prior to their date of presentation at our institute.
In our cohort, NV infection was detected in 15.7% of returning travelers with diarrhea. The closer to the date of return symptoms appeared, the higher the incidence of NV, ranging as high as 21.2% within the first four days after return.
In our cohort, NV infection was shown to be frequent among returning travelers especially in those with diarrhea, with over 1/5 of diarrhea patients tested positive for NV within the first four days after their return to Germany. Due to this prevalence, routine testing for NV infection and hygienic precautions may be warranted in this group. This is especially applicable to patients at an increased risk of spreading the disease, such as healthcare workers, teachers or food-handlers.
[show abstract][hide abstract] ABSTRACT: Erythrocyte acid phosphatase (ACP locus 1), also known as low-molecular-weight protein tyrosine phosphatase, has previously been associated to glycemia, dyslipidemia, and obesity. In this study, ACP1 genotype and activity were tested in 318 women aged 19 to 83 (mean, 51.74 +/- 13.44) years. ACP1 genotype was found to directly correlate to glutathione reductase activity (P < .001) and levels of low-density lipoprotein cholesterol (P = .038). Glutathione reductase activity was in turn found to correlate to a series of cardiovascular risk factors such as systolic arterial pressure (P < .001), total cholesterol levels (P = .018), and low-density lipoprotein cholesterol levels (P = .039). A possible protective effect of ACP1 genotype AA against these cardiovascular risk factors was observed in this study. Furthermore, this work hypothesizes that nutritional riboflavin uptake becomes more crucial as body mass index increases, to counteract oxidative stress and minimize cardiovascular risk. This might be especially true in ACP1 genotypes AC, BC, and CC, which might possibly show the least endogenous protection against oxidative stress.
