Conventional treatment of complete anastomotic obstruction after this procedure is revision surgery, which has high morbidity and mortality. Therefore, less invasive treatments are preferred, such as guidewire tapping, needle knife puncture, and magnetic compression anastomosis [2, 3]. A 72-year-old woman developed obstructive cholangitis 3 months after Roux-en-Y hepaticojejunostomy was performed for a post-cholecystectomy bile duct injury. Complete anastomotic obstruction was observed on percutaneous transhepatic cholangiography and the guidewire could not be passed through the anastomosis (▶ Fig. 1 a). We decided to apply magnetic compression anastomosis by using a double-balloon enteroscope (EN 580; Fujifilm, Tokyo, Japan) because the patient was at a high risk for surgery owing to comorbid diseases (▶ Fig. 2, ▶ Video 1). First, the bowel site of the anastomosis was reached with the double-balloon enteroscope (▶ Fig. 1 b), which was then removed, leaving the overtube in place. The neodymium magnet (4 × 10 mm), which was held by a snare at the tip of the endoscope without the balloon, was introduced into the afferent jejunal limb through the overtube (▶ Fig. 3, ▶ Fig. 4 a). Simultaneously, the neodymium magnet (3 × 10 mm) was inserted into the hepatic side of the obstruction through the percutaneous transhepatic cholangiography catheter (▶ Fig. 4 a). After confirming that the magnets were aligned in the fluoroscopy, the magnets were released. After 8 days, the magnets were seen to be coupled on fluoroscopy (▶ Fig. 4 b) and were removed by re-entering with the double-balloon endoscope. In the same session, the percutaneous transhepatic cholangiography catheter was advanced through the new E-Videos ▶ Fig. 1 Complete obstruction of the Roux-en Y hepaticojejunostomy anastomosis (arrow). a Percutaneous transhepatic cholangiography view. b Double-balloon enteroscope view. ▶ Fig. 2 An illustration of magnetic compression anastomosis using a double-balloon enteroscope (asterisk) and percutaneous transhepatic cholangiography (arrow) performed for complete obstruction of Roux-en-Y hepaticojejunostomy anastomosis.

There is a critical need to diagnose porphyria, given its multisystem nature and the poor prognosis associated with incurable cases. Here we present the case of a 27-year-old female patient who had severe abdominal pain and who was operated on due to ileus with tetraparesis that manifested following an operation. The patient had muscle weakness in four limbs and symptoms of sympathetic hyperactivity and electrolyte imbalance. Moreover, neurophysiological studies supported acute axonal polyneuropathy. Owing to the neurological symptoms, electrophysiological studies, metabolic disorders, and the severe abdominal pain noted, porphyria was suspected. Porphobilinogen and ALA levels increased in the 24-hour urine test, and the patient was diagnosed with acute intermittent porphyria. In patients who have unexplained recurrent abdominal pain with additional autonomic dysfunction, neurological and / or psychiatric findings, porphyria, a rare disease, should come to mind.

LANSS, sLANSS, DN4 and painDETECT are scales which are commonly used worldwide. There are not many studies comparing these screening tools in specific neuropathic pain subgroups. The aim of this study is to compare the utilities of LANSS, sLANSS, DN4 and PainDETECT for the diagnosis of diabetic neuropathic pain. Methods One hundred-one individuals without diabetic neuropathic pain were included in control group, 102 patients with diabetic neuropathic pain to DNP group. LANSS, sLANSS, DN4 and painDETECT scores of the groups were compared. Results The difference between the groups was significant for all questionnaires and for all questions/titles they included. DN4 had the highest sensitivity and painDETECT had the highest specificity. Conclusions All questionnaires seemed to be useful for detecting diabetic neuropathic pain. DN4 had a high specificity and sensitivity. PainDETECT, also had a high sen...

Previous studies demonstrated that F-wave latency should be used to detect this early neuropathic process. The aim of this study is to evaluate the sensitivity of lower/upper extremity F latency ratios in detecting the early neuropathy in patients with diabetic neuropathic pain. 44 patients with diabetic neuropathic pain (DNP) and 44 control subjects whose both conventional nerve conduction studies and F-wave latencies were within normal limits were included to the study. We compared the nerve conduction parameters and lower/upper extremity (tibial/ulnar) F latency ratios of the groups. Tibial F latency was significantly prolonged and tibial/ulnar F latency ratio was significantly higher in DNP group. Our results support that F-waves are useful for detecting early diabetic neuropathy and suggest that comparison with a control group will demonstrate a difference even when the in...

The aim of this study is to evaluate the rate of neuropathic pain in neurology outpatient clinics by using valid and reliable scales and review the treatments of patients. Methods: The study was conducted for 3 months in eleven tertiary health care facilities. All outpatients were asked about neuropathic pain symptoms. Patients with previous neuropathic pain diagnosis or who have neuropathic pain symptoms were included and asked to fill painDETECT and douleur neuropathic en 4 questions (DN4) questionnaire. Patients whose DN4 score is higher than 3 and/or painDETECT score higher than 13 and/or who are on drugs for neuropathic pain were considered patients with neuropathic pain. The frequency of neuropathic pain was calculated and the treatments of patients with neuropathic pain were recorded. Results: Neuropathic pain frequency was 2.7% (95% CI: 1.5–4.9). The most common caus...

Unfortunately, nerve damage is still a major problem regarding health, social and economic issues. On this study, we used vascular graft and human cord blood derived stem cells to find an alternative treatment solution to this problem. MATERIAL AND METHODS: We used 21 female Wistar rats on our study. They were anesthetized with ketamine and we studied right hind limbs. On Group 1, we did a full layer cut on the right sciatic nerve. On Group 2, we did a full layer cut on the right sciatic nerve, and we covered synthetic vascular graft on cut area. On Group 3, we did a full layer cut on right sciatic nerve, and we covered the area with stem cell applied vascular graft. RESULTS: At the end of postoperative 8. weeks, we performed EMG on the rats. When we compared healthy and degenerated areas as a result of EMG, we found significant amplitude differences between the groups on healthy areas wherea...

Clinical manifestations of Fahr's syndrome vary; it may start at different ages and have a variety of presentations. This article discusses rare presentation of Fahr's syndrome with epileptic seizure. These cases are important because they appear to be the first cases in the literature of Fahr's syndrome presenting with generalized tonic clonic seizure.

Idiopathic intracranial hypertension can cause rapid deterioration of visual acuity in some severe cases, and these cases are usually thought to have "malignant" form of this disease. Case. In this paper, we report on a 16-year-old girl who is a typical example for malignant idiopathic intracranial hypertension with a rapid recovery of visual acuity after lumboperitoneal shunt operation. Observations and Conclusions. Malignant form of idiopathic intracranial hypertension must be kept in mind in selected patients to avoid irreversible visual loss.
