PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

We present a case of meningeal and brain metastasis of multiple myeloma. A 60-year-old woman who had been diagnosed as multiple myeloma two years ago, was referred to neurosurgery department because of headache and nausea. The magnetic resonance image of the brain showed a large epidural mass and the parenchymal enhancement. The patient received an operation of tumor removal and cranioplasty. A histological diagnosis of metastatic multiple myeloma was made.

PURPOSE: The aim of this study was to determine whether liver resection treated by using laparoscopy is equally safe for patients who have benign liver mass, hepatolithiasis, hepatocellular carcinoma (HCC), or metastatic liver cancer. METHODS: We performed our study in 32 patients with the following conditions: 17 patients with IHD stones, 7 with HCC, 1 with cholangiocarcinoma, and 7 patients who had colon cancer with liver metastasis. On a retrospective bases, these patients were investigated for clinical history, type of operation, time for the operation, hospital stay, and post operative complications. RESULTS: The target age range was from 37 to 80 years and the mean age was 61.2 years old. The percentage of patients over 60 years old was 68.7%. According to their past history, 8 patients had experienced an upper abdominal operation. In our study there were 9 cases of left hepatectomy (28.1%), 9 cases of left lateral segmentectomy (28.1%), 2 cases of sectionectomy, and 12 cases of wedgeresection. The average operation time was 364+/-148 mins, the average bleeding amount was 417 cc, and the average hospital stay was 13.2 days. There were 8 cases (25%) of postoperative complications developed (2 bile leak, 1 intrabdominal abscess, 1 acute renal failure, 2 wound infection). All cases were improved with conservative management. And there was one case of remnant IHD stone, which had surgical treat and one patient had peritoneal carcinomatosis, who had laparoscopic liver resection for HCC. CONCLUSION: Our study showed that laparoscopic liver resection has advantages; it is less painful, causes a small operative scar, a the short period of hospital stay and has cosmetic benefits. In the future, laparoscopic liver resection could be an important option for the treatment of hepatolithiasis and HCC through improved surgical instrument and skill of operation.

Cranial mononeuropathies, manifesting particulary as opthalmoplegia or facial palsy, are common entities in the dia-betic population. However, sequential multiple cranial neuropathies due to diabetes are much less common. It is often associated with other conditions such as a brain tumor or head trauma. A 61-year-old diabetic man presented with ptosis, opthalmoplegia, and facial palsy which were manifestations of multiple cranial neuropathies involving the left 3rd, 4th, 6th, and 7th cranial nerves throughout five weeks. The pupils were not involved. The neurologic evaluation included a CSF study and a brain MRI with MRA. None of them produced any significant results. Blink reflexes revealed evidence of a left facial nerve lesion. The blood glucose was strictly controlled and steroid therapy was administered. The ptosis of the patientanjx left eyelid improved during treatment and he was discharged after 13 days. In a follow-up examination 3 months after onset, focal neurological deficits including opthalmoplegia and facial palsy on the left side were greatly improved and barely noticeable.

Glioblastomas rarely occur in the posterior fossa. The authors present clinical and pathological findings in a 59-year-old female patient with a glioblastoma growing primarily in the cerebello-pontine angle. The patient presented with a 1-month history of diplopia. Neurological examination revealed right-sided trigeminal and abducens nerve paresis. Cerebral magnetic resonance imaging showed a well-enhancing mass at cerebello-pontine angle. Following near total removal via petrosal approach, the pathological examination revealed a glioblastoma. To the authors knowledge, this represents the first case of glioblastoma arising at cerebello-pontine angle, probably originating from the most proximal part of abducens nerve.

Purpose:
This study was conducted to assess the antidepressant effects of capsaicin in chronic depressive rats and elucidate the mechanism underlying its effects.
Methods:
Male Wistar rats (280~320 g, 8 weeks of age) were subjected to depression induced by chronic unpredictable mild stresses. The rats were exposed to 8 kinds of stresses for 8 weeks. In the last 2 weeks, fluoxetine or capsaicin was injected subcutaneously. The dose of fluoxetine was 10 mg/kg (body weight), while the doses of capsaicin consisted of low (1 mg/kg), middle (5 mg/kg), and high (10 mg/kg). The forced swim test (FST) was conducted to evaluate the immobility time of rats. The immobility time indicates despair, one of symptoms of depression. The change of tryptophan hydroxylase (TPH) in the dorsal raphe was investigated using immunohistochemistry. In the hippocampus cornu ammonis (CA) 1 and 3, glucocorticoid receptor (GR) expression was measured.
Results:
The immobility time in the FST was significantly lower (p < .05) in the low-dose (M = 32.40 ± 13.41 seconds) and middle-dose (M = 28.48 ± 19.57 seconds) groups than in the non-treated depressive rats (M = 90.19 ± 45.34 seconds). The amount of TPH in the dorsal raphe was significantly higher (p < .05) in the middle-dose (M = 249.17 ± 35.02) and high-dose (M = 251.0 ± 56.85) groups than in the non-treated depressive rats (M = 159.78 ± 41.16). However, GR expression in the hippocampus CA1 and CA3 did not show significant differences between the non-treated depressive rats and the capsaicin-injected rats.
Conclusion
This study suggests that capsaicin produces an antidepressant-like effect on chronic unpredictable mild stress-induced depression in rats via the serotonin biosynthesis pathway.

Cough is one of the most common symptoms that causes patients to seek outpatient medical care. If cough persists longer than 8 weeks, common causes of chronic cough, such as upper airway cough syndrome, asthma, and gastroesophageal reflux disease (GERD), should be considered. Although not a common cause of chronic cough, achalasia may cause symptoms very similar to reflux that can lead to its misdiagnosis as GERD. In this report, a 40-year-old woman presenting with chronic cough was initially diagnosed with GERD; however, her symptoms were refractory to conventional GERD treatment. Finally, she was diagnosed with achalasia. Her cough improved completely after pneumatic dilatation. Achalasia is a rare disease accompanied by dysphagia or regurgitation. If cough presumably due to GERD does not respond to treatment, or if the cause of chronic cough is uncertain, physicians should suspect achalasia.
