BACKGROUNDS: Percutaneous radiofrequency neurotomy of posterior primary ramus has been in use as a treatment for persistent, mechanical low back pain for two decades. However, there has been limited studies regarding to prognostic factors related to outcome. We report our experience with at least 2-year follow up with special aftention on prognostic factors. METHODS: Of total 228 patients who underwent percutaneous radiofrequency neurotomy (PRN) of posterior primary ramus for refractory low back pain during last 3 years, 128 patients whose pain was considered to be originated from facets joints or their surrounding soft tissue and responded to temporary blocks were assigned to a group II. All patients had more than 6 months of pain. These patients were compared with 100 patients to whom PRN were provided for chronic nonspecific low back pain without all inclusion criteria (Group I). RF procedures were done under local anesthesia with C-arm intensifier guidance. Pain reliefs were estimated at 1week, 1month, 6months and 2 years using visual analog scale(VAS). For patients with more that 50% reduction of previous pain was regarded as positive responder. Various clinical variables such as age, sex, symptom duration, types of pain, bilaterality, and previous surgery were studied for prognostic factors. RESULTS: Positive responders were 56% at 1week, 46% at lmonth, 18% at 6months, and 13% at 2years after PRN in group I, and 78.9% at lweek, 75.4% at lmonth, 62.5% at 6months, and 54.7% at 2years in group II. Some variables were found to be significantly related to outcome including prominent local tenderness, percussion tenderness, combination of symptoms with pain on gefting up, extension, transitional movement, pain radiating to buttock and/or posterior thigh, and good immediate response. Age, sex, symptom duration, bilaterality, imaging study results, previous lumbar surgery, and degrees of pain relief from diagnostic block were not related to outcome. CONCLUSIONS: These results indicate that PRN of posterior primary ramus has a moderate overall long-term beneficial effect, with no morbidity in our series. But, the long-term good results will be anticipated only in properly selected patients with low back pain originating from facet joints and surrounding structures.

Radiological investigation in patients with clonorchiasis is very important as this is the only method of evaluating the severity of clonorchiasis. In order to correlate the radiologic and pathologic findings of clonorchiasis, fourteen rabbits infested with Clonorchis sinensis and five control rabbits were examined radiologically by ultrasonography, computed tomography and cholangiography and the results were correlated with pathologic findings. Dilatation of the intrahepatic small bile ducts of the liver was due to obstruction by flukes: oval or elliptical small filling defects or irregular margin of the bile ducts on cholangiogram or intraluminal echoes on sonogram represented flukes per se; periductal thickening on sonogram and periductal enhancement of bile ducts on CT were due to inflammatory cell infiltration, adenomatous hyperplasia and periductal fibrosis: band like enhancement at the periphery of the liver on CT represented proliferated bile ducts, destruction of liver cells and resultant fibrosis. The study confirmed the pathological bases for the radiological findings of clonorchiasis in liver and bile ducts and will, perhaps, serve as a basis for the future radiologic-pathological correlation of clonorchiasis and in further clinical and experimental researches in the biliary tract diseases.

We carried out five common electroretinographies according to the recommendation by the International Society of Clinical Electrophysiology of Vision in the eyes of 40 non-diabetic brach retinal vein occulusion. The clear media, no previous history of photocoagulation and no evidence of neovascularization of the retina and/or iris were criteria for inclusion in this study. The data were compared with those of fellow eyes, expecting that this procedure may provide a new feature that could have some clinical significance. The reduction of the summed amplitude of oscillatory potentials, and the timing delay of the cone response b-wave and 30Hz flicker responses were of most frequent occurrence. hence, the reduction of the summed amplitude of oscillatory potentials and the timing delay of the cone response b-wave and 30Hz flicker responses may be valuable indicators. These abnormalities represent overall inner retinal dysfunction. The cone response b-wave timing was more frequently affected than that of the maximal combined response b-wave. This fact may reflect that an ischemic lesion is located in the vicinity of the posterior pole of the fundus.

The incidence of carcinoma of the small intestine is very low in children, and it is also known that the prognosis of this tumor in children is very poor. A case of adenocarcinoma in a 13-year-old girl arising in the jejunum is herein reported. The girl underwent a curative resection and is free of recurrence or metastasis 12 months after operation. This particular case is reported here with a review of the literature.

Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.
