Here in this report a 31?year old pregnant woman with positive serum antiglobulin test against anti-D antierythrocyte antibodies who was treated succesfully with double filtration plasmapheresis (DFPP) is presented. The DFPP was started in the early stage of pregnancy together with intravenous immunoglobulin therapy and the antierythrocyte antibody titer of the patient was successfully maintained in a stable level below 1:64 dilution. She delivered successfully on the 30th week of gestation. The favorable outcome of this patient implies that DFPP is an effective and safe treatment modality in pregnant women with red cell alloimmunization. 相似文献

Small bowel intussusceptions comprise fewer than 10% of all pediatric patients with intussusceptions and most of them are secondary to another pathology. In this report, we discuss the role of surgery in the treatment of intussusception in celiac disease. A 13-month-old girl was admitted with a three day history of progressive abdominal distention and vomiting of bile. There were air-fluid levels on supine abdominal X-ray and ultrasonographic examination demonstrated an intussusception. At surgery, two separate small bowel intussusceptions were encountered. The postoperative course was uneventful. Due to a history of frequent diarrhea and mild abdominal distention developing after the age of seven months, further studies for celiac disease were initiated. Antigliadin and antiendomysium antibodies were found to be strongly positive. Celiac disease was also confirmed by endoscopic small bowel biopsy. Children who present with chronic or transient intestinal obstruction should also be evaluated for underlying celiac disease. Nevertheless, the surgical decision should be based upon clinical observation in this group of patients. 相似文献

Objective
Cubital tunnel syndrome (CuTS) is the second most common compression neuropathy in the arm, but the existence of a compressive cause has not been determined conclusively and the majority of the cases are idiopathic. In this paper, involvement sides of limbs of patients with cubital tunnel syndrome were studied.Material and methods
Between October 2008 and December 2011, the clinical assessment of consecutive operated patients with cubital tunnel syndrome in Rize Education and Research Hospital were analysed. The diagnosis and severity of syndrome was based on electro-diagnostic study.Results
This study included 57 consecutive patients with cubital tunnel syndrome (39 men, 18 women; mean age, 44,7 years; range, 23–79 years; mean age, 44,7 years; range, 23–79 years); 31 patients underwent surgical treatment. Involvement was on the right side in 18 and on the left in 39 patients. Severity scores and MCV were statistically significant between sides.Conclusion
Profound involvement with cubital tunnel was found in left elbow. According to the finding of non-dominant elbow involvement in our study, the exact etiology and ideal management of cubital tunnel syndrome continues to be heavily debated. 相似文献64.

Background
Intragastric band migration is an unusual but major complication of gastric banding. We review our experience with endoscopic removal of eroded gastric bands.Methods
We retrospectively evaluated the cases of 110 morbidly obese patients who underwent adjustable gastric banding between 2005 and 2012 to identify those who experienced band erosion. To remove the migrated band, we used an endoscopic approach with a Gastric Band Cutter.Results
Band or tube erosion occurred in 14 patients (12.7%). The median time interval from the initial gastric band placement to the diagnosis of band erosion was 32 (range 18–52) months. Upper abdominal pain, port site infection, loss of restriction and weight regain were the most common symptoms. We used the Gastric Band Cutter to remove the band endoscopically. It was able to cut the band successfully in all but 1 patient, in whom twisting of the cutting wire required conversion from endoscopy to laparotomy. In 2 patients, the band, after being cut, was locked in the gastric wall and required laparotomic removal. In 1 patient, we performed surgery for intragastric penetration of the connecting tube broken close to the band.Conclusion
The Gastric Band Cutter was successful in dividing the band in all but 1 patient, although we could not always complete the procedure endoscopically. Endoscopic removal seems to be effective and safe for band erosion. 相似文献65.

Aim-Background
While significant changes in the last century have enabled safe and effective total thyroidectomy, the utility and reliability of techniques for patients with benign diseases is debatable. The purpose of this study was to compare the complication rates of division of the isthmus vs. non-division in thyroid surgery performed for bilateral multinodular goiter by experienced endocrine surgeons. To the best of our knowledge, no such study has been published in the literature to date.Methods
This prospective study includes 60 consecutive serial patients who underwent total thyroidectomy. Patients were randomly assigned to a thyroidectomy technique by the arbitrary draw from a bag of paper tags marked as ‘U’ (thyroidectomy without dividing the isthmus) classified as Group 1 or ‘D’ (thyroidectomy by dividing the isthmus) as Group 2. Patients in Group 1 (n=30) had a total thyroidectomy without dividing the isthmus (en bloc), patients in Group 2 (n=30) had total thyroidectomy by dividing the isthmus.Results
Postoperative serum mean calcium and parathyroid hormone (PTH) levels, operation period, visual analogue pain score and recurrent laryngeal nerve paralysis did not differ between the groups. Permanent hypocalcaemia and permanent recurrent laryngeal nerve paralysis were not observed in either group, but total morbidity in Group 1 was higher (p=0.038). Postoperative PTH levels were significantly lower than preoperative PTH levels in both groups; (respectively, p=0.007, p=0.011). No surgical mortality was recorded.Conclusion
Thyroidectomy without dividing the isthmus can be qualified as a safe and applicable surgical method. 相似文献66.

Objectives. We aimed to explore whether the use of methylphenidate relates leptin, ghrelin, adiponectin, and brain-derived neurotrophic factor (BDNF). In addition, the relationship between methylphenidate-related weight loss in attention deficit hyperactivity disorder (ADHD) patients and these biomolecules were evaluated. Methods. Thirty ADHD patients receiving methylphenidate and 20 healthy controls were included. Leptin, ghrelin, adiponectin, and BDNF levels were measured at baseline and after two-month treatment in both groups. Results. At baseline, leptin, ghrelin, adiponectin, and BDNF levels were similar in the ADHD and control groups. The most common adverse events occurring in the ADHD group after a 2-month treatment period included loss of appetite (70%) and weight loss (66.7%). A significant difference was found in body weight, BMI, and CGI scores of the ADHD patients after the treatment. While post-treatment ghrelin and adiponectin levels were significantly higher in the ADHD group, BDNF level was significantly lower. Post-treatment decrease in leptin levels was not significant. Conclusions. Leptin and BDNF were not associated with poor appetite and/or weight loss due to methylphenidate treatment. However, ghrelin and adiponectin might be biomolecules that play a role in underlying neurobiological mechanisms of methylphenidate-related appetite or weight loss. 相似文献

Purpose
Vitamin K deficiency bleeding is one of the most common causes of acquired hemostatic disorder in early infancy. Although vitamin K is practiced routinely after every birth in Turkey, children with type of vitamin K deficiency bleedings (L-VKDB) can be encountered. We aimed to evaluate the clinical features of the children with L-VKDB reported from Turkey.Methods
Between 1995 and 2013, 48 studies reporting 534 children with L-VKDB were evaluated in this study.Results
Of the 534 reported children (178 girls, 356 boys), 486 (91 %) were extremely breastfed. The most common bleeding sites were intracranial hemorrhage, gastrointestinal, and umbilical in 414 (77.4 %), 33 (6.2 %), and 33 (6.2 %) children, respectively, and 35 (6.6 %) children had been diagnosed incidentally without any bleeding. The etiology of 399 (74.7 %) children were classified as idiopathic, whereas 135 (25.3 %) were secondary. Intramuscular vitamin K was administered in 248 (46.4 %), not administered in 228 (42.7 %), and the administration of vitamin K were not determined in 58 (10.9 %) children. The outcomes of Turkish cohort showed that 111 (20.8) children died, 257 (48.1 %) cases developed neurologic deficit (mainly epilepsy and psychomotor retardation), and only 166 (31.1 %) patients recovered without squeal.Conclusions
The compliance of prophylactic measures in Turkey does not seem to be satisfactory. As a further measure of tomorrow, we vigorously emphasize that a national surveillance program may be initiated. An additional intramuscular dose or oral supplementation of vitamin K especially for exclusively breast-fed infants may reduce this catastrophic problem in our country. 相似文献70.
