Tibia valga has been described as a consequence of non-displaced fractures of the proximal metaphysis of the tibia in children. There has been considerable speculation about the cause of this deformity. Four cases of estabilished valgus deformity following injury to the proximal tibia metaphysis in children are presented. In one case of them, it was showed that an infolding of a portion of the periosteum of the tibiain medial opening of this fracture. It was treated by surgical clearence of the infolding periosteum and varus osteotomy with slight over-correction and partial fibulectomy. The recurrence of valgus deformity was absent during post operative one year. In another case, roentgenogram showed an asymmetrical growth arrest line of the pmximal tibia. The presence of asymmetrical growth arrest lines in the pmximal metaphysis of the tibia demonstrates that the valgus deformity in this patient was caused by overgrowth of the medial portion of the proximal tibial epiphyseal plate. In the remainder, we observed the deformity developed without any specific cause.

Deliberate hypotension reduces bleeding in a wound, there by providing the surgeon with both better visibility and technical freedom for a more definitive dissection and minimizes the need for blood replacement, thereby reducing the risks of transfusion reactions, hepatitis, and acquired immune deficiency syndrome (AlDS). anesthesia With major development in surgery for spine problems in this century there are many reports and studies about the pathophysiology of spine, cord hemodynamics and functional monitoring about spinal cord activity during induced hypotension. Although by the comparative studies of vasodilator deliberate hypotension with nitroprusside was found to induce a reliable and rapid drop in blood pressure, we have found some different responses to the chosen vasodilators between the older, less active groups and the healthy, robust, and physically active groups. In this study we evaluated the hypotensive anesthesia for 42 cases of spinal surgery-posterior stabilization, spinal fusion, laminectomy, osteotomies, and discectomy-performed at Kwangju Christian Hoispital from May 1987 to May 1988. The result of our study was as follows: 1) Halothane and enflurane were used as primary anesthetics in 31 and ll cases respectively. Nitroprusside, hydralazine and both of this two vasodilatora were supplementarily used for inducing hypotensin in 14, 16 and 5 cases, respectively. 2) Although in many paient particularly in the older and less active groups, the combination of halogenated anesthetics and hydralazine are sufficient to produce appropriate operating conditions, in healthy, robust and physicaly active groups nitroprusside or even the combination of two vasodilators are required. 3) The mean arterial pressure of the lowest blood pressure in the induced hypotension was 60.5+/-11.6 mmHg. 4)The mean blood loss and blood replacement was 1242.2+/-769 ml and 925.4+/-854 ml respectively. 5) In the intraoperative period gas analysis arterial CO2 tension was 34.2+/-6.6mmHg and other values was within normal limit. 6) There was no significant perioperative and postoperative complication due to induced hypotension itself. In conclusion, the technique of using induced hypotension with inhalation anesthetics supplemented by nitroprusside, hydralazine, or both is safe and useful one to use in performing surgery for spinal problems.

Experiments were performed in mice (Balb/C) to support the basic efficacy of the human immunoglobulin (IgG) preparation. The antibacterial activity of IgG purified from human sera was examined with or without the quinolone agent, ciprofloxacin (CPFX), against Pseudomonas aeruginosa isolated from clinical specimens. Results were as follows: Antibacterial activities in terms of percentage of survivors, after administration of Ps. aeruginosa into mouse intraperitoneal cavity were in the following order, single IgG group, CPFX administration after IgG pretreatment group, IgG and CPFX combined administration group and CPFX alone group. The number of living bacteria was monitored in blood and liver tissue of mice infected with Ps. aeruginosa and treated by IgG administration. The increase of living bacteria in liver was more drastic than that in blood. Leukocytosis was observed in mice injected with IgG, excluding those only with ciprofloxacin, after 8 hours of administration to see a decrease to normal number of bacteria after 18 hours. No significant difference was noticed between pretreatment group and post treatment group. In vitro susceptibility test of IgG against Ps. aeruginosa, minimal inhibitory concentration (MIC) was 250 µg/ml, resistant to IgG, regardless of a combined administration with CPFX. In vitro test revealed that the IgG itself did not have anti-Ps. aeruginosa activity.

Proliferating trichilernmal tumor is a rare benign solitary tumor that may be histopathologically misinterpreted as squarnous cell carcinoma. It affects frequently the scalp of elderly women. We present herein a case of proliferating trichilemmal tumor in an 87-year-old male who had had a slowly growing tumor on the scalp for 30 years.

A 51 year old female patient underwent resection of pheochromocytoma under general anesthesia. Thiopental sodium 250mg and succinylcholine 50 mg were used for endotracheal intubation, followed by N2O, O2 and ethrane for induction and maintenance. For the management of blood pressure during surgical amnipulation, we used sodium nitroprusside dripping. After tomor resection, blood pressure was controlled by dopamine dripping and intravenous lactated Ringer's solution. The patient tolerated anesthesia and surgery well despite the episodic hemodynamic changes. Although tolerated anesthesia and surgery well despite the episodic hemodynamic changes. Although specific anesthetic drugs have been recommended, we believe that optimal preoperative preparation, a gentle induction of anesthesia, and good communication between surgeon and anesthesiologist are most important for anesthetic management.
