AIM To investigate the correlation of congenital lumbosacral abnormalities with neurological signs in young patients with low back pain (LBP) MATERIAL AND METHODS: The study included 401 patients with LBP that lasted longer than 2 weeks. All cases were screened by standard lumbosacral x-rays for the presence of the most common congenital vertebral abnormalities i.e. spina bifida occulta (SBO) a...

Primary small bowel bezoars are rare and cause acute abdomen due to small bowel obstruction (SBO). A 69-year-old Japanese man presented with epigastric pain associated with fullness. Physical examination of the abdomen showed no marked signs of peritoneal irritation. An erect X-ray film of the abdomen showed small bowel obstruction. Computed tomography (CT) showed a dilated small bowel loop pro...

A pericecal hernia is a type of internal hernia, which rarely causes small bowel obstruction (SBO). At our institution, a 92-year-old man presented with vomiting and abdominal pain. He was conservatively treated with a diagnosis of SBO. After 2 weeks of copious drainage output, he was taken to the operating room. Laparoscopy revealed a pericecal hernia that was successfully reduced. We conclude...

In this research, a Surrogate-Based Optimization (SBO) method is coupled with reanalysis techniques to improve the computational efficiency during optimization even further. The reanalysis techniques are used to speed up a reduction and a substructuring method, Craig-Bampton, which is utilized at the analysis step of the proposed SBO strategy. This strategy is suitable for solving problems wher...

Small bowel obstruction (SBO) is one of the most common acute surgical conditions that require urgent evaluation and treatment. Several common causes are known in the general surgical practice, and the causes are different in the developing and developed world. In this article, we present a case of an acute SBO secondary to ileo-ileal knotting in a 50 years old Ethiopian female patient. The dia...

A total of 144 barrows and gilts (initial BW = 44 kg) were used in an 82-d experiment to evaluate the effects of dietary fat source and duration of feeding fat on growth performance, carcass characteristics, and carcass fat quality. Dietary treatments were a corn-soybean meal control diet with no added fat and a 2 × 4 factorial arrangement of treatments with 5% choice white grease (CWG) or soyb...

Abstract The epoxidation process of soybean oil (SBO) and peracid produced by 50 wt% hydrogen peroxide (H 2 O ) formic acid (FA) was studied with sulfuric SO 4 as a catalyst. Three reaction parameters, including temperature, FA-to-SBO ratio, H -to-SBO were investigated, along the combined effect on oxirane value (OV). Based response surface methodology (RSM), Box-Behnken design (BBD) used to op...

A validated questionnaire to assess the impact of small bowel obstructions (SBO) on patients' quality of life was developed and validated. The questionnaire included measurements for the impact on the patients' quality of life in respect to diet, pain, gastrointestinal symptoms and daily life. The questionnaire was validated using 149 normal subjects. Chronbach alpha was 0.86. Test retest relia...

Without assuming any knowledge of the underlying physical topology, the conventional P2P mechanisms are designed to randomly choose logical neighbors, causing a serious topology mismatch problem between the P2P overlay network and the underlying physical network. This mismatch problem incurs a great stress in the Internet infrastructure and adversely restraints the performance gains from the va...

Properties of strontium tetraborate (SBO) and features of as-grown anti-parallel domains are summarized. From the point of view of nonlinear optics, these domains form nonlinear photonic crystals (NPC). Applications of NPC to the deep ultraviolet generation and fs pulse diagnostics are described. NPC and SBO are prospective media for the creation of a widely tunable source of fs pulses in the v...
