We report a case of a 59 year-old female with hyperlipoproteinernia who had xanthoma tuberosum, xanthoma tendinosurn and xanthoma planum. Yellowish nodules appeared on the right elbow 26 years ago and the lesions gradually increased in size and spread to the elbow, hand, knee, foot and achilles tendon. Except for the skin lesion, she was normal on physical examination. The laboratory findings showed that the serum cholesterol, beta lipoprotein and total lipid were increased. The beta band was rnarkedly elevated on electrophoresis, which suggested type IIa hyperlipoproteinemia. Histopathological findings shc wed many aggregates of foam cells and foreign body giant cells were seen in the dermis.

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.

PURPOSE: The influence of the modified process in the fiber-reinforced post and resin core foundation treatment on the fracture resistance and failure pattern of premolar was tested in this study. MATERIALS AND METHODS: Thirty-six human mandibular premolars were divided into 4 groups (n = 9). In group DCT, the quartz fibre post (D.T. Light-post) was cemented with resin cement (DUO-LINK) and a core foundation was formed with composite resin (LIGHT-CORE). In group DMO and DMT, resin cement (DUO-LINK) was used for post (D.T. Light-post) cementation and core foundation; in group DMO, these procedures were performed simultaneously in one step, while DMT group was accomplished in separated two steps. In group LCT, the glass fiber post (LuxaPost) cementation and core foundation was accomplished with composite resin (LuxaCore-Dual) in separated procedures. Tooth were prepared with 2 mm ferrule and restored with nickel-chromium crowns. A static loading test was carried out and loads were applied to the buccal surface of the buccal cusp at a 45 degree inclination to the long axis of the tooth until failure occurred. The data were analyzed with MANOVA (alpha = .05). The failure pattern was observed and classified as either favorable (allowing repair) or unfavorable (not allowing repair). RESULTS: The mean fracture strength was highest in group DCT followed in descending order by groups DMO, DMT, and LCT. However, there were no significant differences in fracture strength between the groups. A higher prevalence of favorable fractures was detected in group DMT but there were no significant differences between the groups. CONCLUSION: The change of post or core foundation method does not appear to influence the fracture strength and failure patterns.

The coexistence of pheochromocytoma and renal artery stenosis has been recognized since 1958, but it is rare. We have experienced an anesthetic management of 43-year-old female patient of renovascular hypertension associated with right adrenal pheochromocytoma. Proper preoperative preparation, sufficient sedation, smooth induction, complete analgesia and good muscle relaxation were very important. Relative cardiovascular stability was achieved with sodium nitroglycerine, sodium nitroprusside and verapamil during tumor manipulation. After the tumor was removed, we could control the hypotension with dopamine, dobutamine, crystalloid and colloid. On the operative field there was no definite anatomic stenosis of renal artery and it was suggested that leakage of catecholamines from pheochromocytoma causes functional, reversible spasm of renal artery and thus renovascular hypertension.

Ventriculoperitoneal(VP) shunting has been associated with a variety of complications. CSF ascites secondary to VP shunting is very rare. We report a case of 68-year-old man with VP shunt in whom subclinical peritoneal infection presented with ascites. The patient was treated successfully with antibiotics and removal of the shunt. CSF ascites complicating VP shunt is reviewed and the pathogenesis of this condition is discussed.
