PURPOSE: To evaluate the surface anatomy of the central sulcus(CS), precentral gyrus(PrCG) and postcentral gyrus(PoCG) on the basis of sulci pattern on MR images. MATERIALS AND METHODS: The MR images were obtained in the plane 10 degree angled to the orbitomeatal line. The MR images of 120 subjects(6 months to 79 years) with normal anatomy were analyzed and another four subjects with known space occupying lesions were also reviewed. RESULTS: The identification of gyri was feasible on the axial T1WI from anterior to posterior and from upper to lower images. The STS demonstrated symmetric pattern on both sides in 84 of 120 cases (70%), including two cases of prominent STS pattern. The asymmetric pattern was seen in 36 of 120 cases (30%):14 of 120 cases (12%) on the right and 22 of 120 cases (18%) on the left at 4.5 cm above the level of the splenium of corpus callosum. The PrCG and PoCG and CS were identified well in all cases with the use 'of the sulci pattern. CONCLUSION: The identification of the gyri on the basis of the cerebral sulci pattern on MR images is useful and important when locating the space occupying lesion of the brain.

Some of the techniques for bone grafting for delayed union or nonunion of the long bone are used currently. In 1991, at arthroscopy workshop in Phoenix, Arizona, Lanny L. Johnson, M.D. reported a case of endoscopic bone grafting for the delayed union on the humerus. He suggested the possibilities of endoscopic bone grafting such as minimal incision, magnified visualization, accurate debridement, accurate graft placement, vascular preservation, outpatient surgery and reduced cost. The author performed endoscopic bone grafting and extra-articular adhesionlysis on the delayed union of femur with extra-articular ankylosis. The patient was a 28 year old housewife with blood type Rh(-). The duration after initial operation was more than 9 months. The result of the graft was satisfactory. In the future endoscopic bone grafting could be performed for nonunion, delayed union and congenital bone defect.

Effect of infusion and bolus injection of lidocaine on the pressure response to the increased intracranial pressure(ICP) was investigated in urethane-anesthetized rabbits. 1) Arterial blood pressure(BP) and ICP were significantly raised by infusing saline(0.05ml/min) into an epidural balloon. 2) Infusing of lidocaine(0.5mg/kg/min) into an ear vein minutely inhibited the elevation of BP and ICP when infusing saline into an epidural balloon. However, infusion of lidocaine(1.5mg/kg/min) markedly inhibited the elevation of BP and ICP. 3) Repeating the infusion of saline into the epidural balloon with intervals, the duration reached to the level of 80-10 mmHg ICP was gradually shortened. Each depressor response to the first, second and third injection of lidocaine(3 mg/kg) was similar. The first injection transiently reduced the elevated ICP, but the second and third injection reduced that significantly and the reducing effect was gradually prolonged according to repeating the lidocaine injection. These results show that lidocaine could delay the elevation of ICP and reduce the previously increased ICP by infusing saline into an epidural balloon.

Salmonella infection can cause an asymptomatic intestinal carrier state or clinical diseases such as enterocolitis presenting abdominal pain, fever, vomiting, or diarrhea. Salmonella usually invades Peyer's patch of terminal ileum or ascending colon. Sepsis is not common and acute renal failure secondary to rhabdomyolysis is rare. The causes of rhabdomyolysis are trauma, excessive exercise, alcohol, seizure, metabolic abnormality, and infection. Infections account for less than 5% of the reported causes of rhabdomyolysis and resulting acute renal failure. The mechanisms underlying rhabdomyolysis due to infection are direct muscle invasion, toxin production, and nonspecific effects that can occur with infections such as fever, dehydration, acidosis, and electrolyte imbalance. We report a case of sepsis and acute renal failure secondary to rhabdomyolysis associated with Salmonella infection.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.
