The MR images of 13 patients with brain abscesses were retrospectively reviewed. The abscesses were solitary in 11 patients and multiple in 2 patients. They were located in the corticomedullary junction of the cerebral hemispheres(11) and cerebellum (2).: The sizes of the abscesses were variable, ranging from 1 cm to 5 cm in diameter. They were round (5), oblong (4) or multilobulated (4) in shape. Massive surrounding edema was found in 12 patients. The signal intensity of the abscess contents was hypointense to gray matter and hyperintense to CSF on T1-weighted images, and hyperintense to gray matter on both proton-density-and T2-weighted images. In 5 patients the abscess contents were heterogeneous on both T1-and T2-weighted images. The signal intensity of the abscess walls was isointense(11), slightly hyperintense (1) or hypointense (1) relative to gray matter on T1-weighted images, whereas they were isointense (4) or hypointense (9) on T2-weighted images. Of 10 patients with Gd-enhanced-T1-weighted images, 5 patients(50%) showed thin, smooth, rim enhancement, while the other 5 patients revealed somewhat irregular thick wall enhancement Satellite or daughter abscesses were found in 6 patients. Meningeal or ventricular wall enhancement suggesting meningitis or ventriculitis was associated in 3 and 1 patient, respectively. In conclusion, the characteristic morphology and intensity of the abscess capsule, massive surrounding edema, satellite abscess and associated meningitis or ventriculitis are characteristics of the brain abscess, even though they are not entirely specific to allow for accurate diagnosis in all patients.

BACKGROUND: Although palmoplantar epidermal cysts have long been associated with develop ment following implantation of an epidermal fragment as a result of a penetrating or blunt injury, the pathogenic mechanism is still not fully understood. Since 1987, many cases have been reported in which human papillomavirus(HPV) could be associated with palmoplantar epidermal cysts. OBJECTIVE: In this study, we evaluated the clinicopathological findings of palmoplantar epidermal cysts and investigated them for the presence of HPV in order to examine the role of HPV in the pathogenesis of this disorder in Korea. METHODS: The clinical, histological, immunohistochemical studies were performed on seven cases of plantar cysts, and two cases of palmar cysts. RESULTS: No previous trauma history was seen. Histopathologically, parakeratotic nuclei, or vacuolar strutures within the keratinous mass in the cyst cavity were found. However, we could not find intracytoplasirnic eosinophilic bodies in the wall, the cyst content, or the overlying epidermis. The dyskeratotic keratinocytes were observed in 3 cases. Papillomavirus common antigens were not detected by immunohissochemical staining. CONCLUSIONS: Palmoplantar epidermal cysts in Korea have some different histological features compared to those of HPV 60-associated cases in Japan and we could not detect the immunohistochemical evidence of HPV infection in our cases.

We report a case of anosacral cutaneous amyloidosis in a 74 year-old-man. The skin finding is a patch of the size of a childs palm on the sacral area, consisting of brownish macular lines that radiate frorn the anus. Histopathology revealed defiosits of homogenous eosinophilic mateial s in the papillary dermis. Congo red staining and dylon staining was positive. Immuohistochemical staining using anti SAP antibodies and anti-keratin antibodies showed positive reactions.

Posteroanterior radiographs of normal wrist were taken in seventeen volunteers, and analysed to determine the dynamic relationships between the radiocarpal and midcarpal joint during radioulnar deviation. The total arc of radioulnar deviation was 59 degrees, and the motion was 44% radiocarpal and 56% midcarpal. During radioulnar deviation, the motion at the midcarpal joint was more than that at the radiocarpal joint. It is suggested thst dorsoradial and palmar-ulnar flexion as it occurs at the midcarpal joint can be correlated in radio-ulnar deviation of the wrist more than the coronal sliding motions as it occurs mainly at the radiocarpal joint.

Adhesion around tendons of the hand and wrist and subsequent limitation of motion, is one of the major complications after tendon surgery. In addition to the tendon surgery such as tendon repair or graft, infection, open reduction of fracutres, and burn scar contracture could be the casuses of tendon adhesion. Tenolysis and adequate postoperative rehabilitation program, has been proved to be effective in preventing of adhesion, whatever the cause may be, if its continuity is maintained. In order to evaluate the efficiency and problems of tenolysis, we reviewed 37 fingers of 31 patients who had been treated by tenolysis at Seoul National University Hospital from 1981 to 1991. There were 20 men and 11 women, and the average age was 28.2 years(9-45 years). The causes of adhesion were various; 24 fingers(64%) after tendon repair or tendon graft, 3 fingers(8%) after infection, 4 fingers(10%) after treatment of fracture, 4 fingers(10%) after burn scar contracture, and the other 2 fingers(5%) after curettage of enchondroma. Involved tendon were flexor tendon in 28 fingers and extensor in 9. The average duration of follow-up was 17 months(13 months to 4 years). Active motion of involved finger was started within 2 days after operation. The Total Active Motion(TAM) after operation was average 213°(100°-260°), compared to 123°(40°-180°) before operation. According to Strickland formula which was modified by us, the postoperative results were excellent in 17 fingers, good in 9 fingers, fair in 6 fingers and poor in 5 fingers. In 24 cases who had tenolysis after repair or graft, 19 case(79%) were rated as excellent or good. But in 7 cases whose causes of adhesion were infection or burn scar contracture, only 3 cases(42%) were rated as excellent or good. Compairing the results between younger(less than 30 years of age) and older(more than 30 years of age) group, the younger group showed excellent and good in 8496 and the older group in 41%, The complications were tendon rupture in 3 fingers and minor infection in 2 fingers, respectively. In summary, tenolysis was considered as a useful procedure to improve function of tendon bound down in scar tissue. And the results were better in younger age group(p < 0.05) and in previous tendon repair or graft(p < 0.05) group.

Congenital radial clubhand is a rare deformity, which is characterized by total or partial absence of the radial ray of forearm and hand. We experienced 9 radial clubhands in 7 patients during the last 12 years. Excluding 3 clubhands in 2 patients which were very mild in their deformity, 6 clubhands in 5 patients were operated. Radialization was done in 5 clubhands, and centralization in one. Concomitant corrective osteotomy of ulna was combined in all. The results of the surgical treatment were evaluated by ; radiological findings including Hand-forearm angle(HFA), Hand-forearm position(HFP) and Ulnar bowing(UB) range of motion of the wrist ; and parents' satisfaction. Patients were followed up for average 2 years and 6 months, ranging from 1 to 6 years. All the radiological findings were improved. Although their range of wrist motion was not increased, this was changed into more functional position, that is the radial deviation decreased but ulnar deviation increased. Most parents were satisfied with the surgical results.

Intrinsic plus deformity, which results in severe functional impairment of the hand, is caused by contracture of intrinsic muscles. This deformity can be resulted from many causes such as ischemic damage, spasm of intrinsic muscles, thermal injury, and so on. The surgical release of tightened intrinsic muscles, may be the only solution to make usable hand, especially for severe cases. Sixty five digits in 22 patients who were operated on from 1982 to 1992, were evaluated retrospectively, to analyse the effects of surgery for intrinsic plus hand. Among 65 digits, 13 were thumbs and 52 fingers. The mean age of the patients was 26 years and 8 months and 17 cases were males and 6 females. The causes were ischemic damage by laceration or crushing injuries in 11 patients, compartment syndrome in 5, cerebral palsy in 5, and burn in one. Involved digits were thumb only in 4 patients, thumb and fingers in 9, and fingers in nine. All the digits were classified preoperatively by Zancolli's classification. In 13 thumbs retropulsion contracture was 4 and adduction-antepulsion contracture was nine. All of the thumbs were treated by intrinsic release and Z plasty(or rotational flap). Other procedures including arthrolysis, arthrodesis and tendon reconstruction were combined in 9 thumbs. In 52 fingers, in addition to distal release, arthrolysis was combined in 12 fingers, and arthrolysis plus volar plate release were combined in 4 fingers. For the assessment, our criteria, based on subjective satisfaction of the patient and range of motion, was used. The duration of follow up was from one year to 9 years with the average of 26 months. In 14 thumbs the results were excellent in 2, 6 good, 4 fair, and one poor. In 52 fingers excellent was 12, 24 good, 13 fair, and 3 poor. In summary we could improve the function of intrinsic plus deformity by appropriate sugery, and their results were good.
