In recent years, treatment using implants has become common. Since 2016, dental implants have been insured as part of strengthening health insurance coverage. Consequently, the demand for implants is increasing. Accordingly, the importance of implant maintenance has been emphasized. Of which, implant retrievability is an important factor in implant success. Although the screw-retained type is an advantageous easy-to-retrieve prosthesis, an occlusal point cannot make it to the central axis of the implant. Thus, we aimed to introduce an implant setting method (screw hole indexing) that enables the maintenance of the proper occlusal point and enables retrievability by marking the screw holes of the implant.

We experienced an unusual case of acute encephalopathy in a 4 month-old boy He was admitted to our hospital because of lethargy and seizures after preceding symptoms of upper respiratory tract infection a few days before admission. On admission, he was in semicomatous mental state with decorticated rigidity. Laboratory tests showed normal blood sugar, ammonia, and transaminase levels. CSF was acellular and sterile. Brain MRI in both 71 and 72 weighted-image showed high signal density in both thalami and caudate nucleus head. After recovery, neurologic sequales of developmental delay, mental retardation, right hemiplegia and seizure remained. We report a case of acute encephalopathy that have clinical course similar to Reye syndrome but have specific brain image.

PURPOSE: Heptaplatin (SKI-2053 R) is a new platinum analogue, with a better toxicity profile than cisplatin, and has antitumor activity even in cisplatin resistant cell lines. 5-fluoruracil (5-FU) has shown synergy with platinum compounds. This phase II trial was designed to determine the efficacy and toxicities of heptaplatin/ 5-FU (5-fluorouracil) for treating stomach cancer. MATERIALS AND METHODS: Thirty-two patients with advanced, measurable gastric adenocarcinomas were enrolled in this trial. The treatment consisted of heptaplatin, 400 mg/m2/day (1 hour IV infusion), on day 1 and 5-FU, 800 mg/m2/day (12 hours IV infusion), on days 1 to 5. The cycles were repeated every 3 weeks. RESULTS: Of the 26 evaluable patients, 9 had partial responses and 1a complete response (overall response rate, 38%; 95% confidence interval, 19~57%). The median response duration was 23 weeks (range: 4~60 weeks). The median time to progression was 26 weeks (range: 3~68 weeks). The grades III-IV toxicities were mostly hematological toxicities: leucopenia was observed in 11 patients (35%) and thrombocytopenia 4 (13%). No definite neuropathy was observed. Grade I-II nephropathy was also noted: grade I high BUN/creatinine levels occurred in 5 patients (16%), grade II proteinuria 2 (6%), grade I proteinuria 5 (16%). Neutropenic fever developed in 5 patients (16%) and 1 died of pneumonia in a neutropenic state. CONCLUSION: This study suggests that the regimen of Heptaplatin/5-FU should be effective and have a favorable toxicity profile for the patients suffering with advanced stomach cancer.

BACKGROUND: The terminal destruction of the striatal dopaminergic axon can produce the retrograde degeneration of nigral dopaminergic neurons. An analyses of the postsynaptic dopamine D1 & D2 receptors and the DOPAC/DA level, revealed that this model mimics the early course of Parkinson's disease in humans. We evaluated the time course of the retrograde dopaminergic neuronal degeneration and the pattern of dopaminergic neuronal loss in the substantia nigra after various doses of 6-hydroxydopamine (6-OHDA) injections in the striatum of rats. METHODS: Different doses of 6- OHDA (0.0, 1.25, 2.5, 5, 10 ug/ul in 3.5 ul of saline) were unilaterally injected into the right striatum of rats using a stereotaxic frame. Structural and functional deficits were quantified and compared using apomorphine-induced rotations and tyrosine hydroxylase-immunoreactive (TH-IR) cell numbers in the substantia nigra pars compacta (SNpc) at 3, 6, 9 weeks after lesioning. RESULTS: Striatal 6-OHDA lesions produced dose-dependent decreases in TH-IR cell numbers in SNpc at 3 weeks (-3.8%, 17.9%, 41.2%, 58.5%, 69.9% cell loss compared with the contralesional side respectively), where the ventrolateral portion of the SNpc were more affected. As time progressed, nigral cell loss was significantly increased in all dosage groups and the lesion extended to the medial side of the SNpc and the ventral tegmental area. Apomorphine-induced rotations did not correlate well with nigral TH-IR cell loss. CONCLUSIONS: Intrastriatal injections of 6-OHDA, results in time-dependent and dose-dependent progressive degeneration of nigral dopaminergic neurons. We conclude that this rat model can be useful for the evaluation of further neuroprotective and neurotrophic therapies.

The occurrence of Non-Hodgkin's lymphoma (NHL) during pregnancy is rare. The optimal management of NHL during pregnancy requires special considerations. Because of their rapid progression, women with aggressive NHL should receive standard chemotherapy despite the potential risk to the developing fetus. We experienced a case of 30-year-old pregnant woman diagnosed as a diffuse large B cell NHL at 28 weeks of gestation, who was taken 4 cycles of CHOP combination chemotherapy and delivered a male baby weighing 2660g at 39 weeks of gestation. Following delivery, she received additional 3 cycles of chemotherapy with 4500cGy of radiotherapy on the neck. While she has been in complete remission of NHL over 6 years, her baby have developed mild developmental retardation.

Nerve sheath myxoma or neurothekeoma, a rare cutaneous neoplasm probably originating from the nerve sheath, is classified into three groups as classical, cellular, and mixed types based on cellularity, mucin content and growth patterns. Only two cases of nerve sheath myxoma have been reported in the Korean literatures. We report a case of nerve sheath myxoma occurring on the scalp of a 29 year-old woman. It was identified as the mixed type by histopathological, immunohistochemical and electronmicroscopic findings.
