Triple arthrodesis was performed on 167 feet in 153 patients at the Department of Orthopaedic Surgery, Seoul National University Hospital, during the 19 years from July 1957 to March 1976. Review of statistics, technical problems, and complications has led to following conclusions. 1) Of the total of 167 feet, residual poliomyelitis was the most common etiology with 127 feet (76%). 2) The youngest age was 5 years and the oldest 54 years, the 12–17 year group with 84 feet occupying half of the cases. 3) 79 feet (46.7%) had equinovarus deformity and 27 feet had equinocavovarus. 13 feet had no deformities. 4) Hoke's lazy S incision was utilized in 110 feet and Olliers incision in 57 feet. Hokes technique was employed in 118 feet and Lambrinudi's technique or its modification in 44 feet, while in the 5 feet without deformity exeresis alone was performed. Steinmann pins were used in 121 feet for temporary internal fixation and staples were used in 39 feet. 7 feet had no internal fixation. The senior author (D.Y.L.) routinely employs Hoke's incision, Hoke triple arthrodesis and Steinmann pin fixation, while when there is no deformity simple exeresis may be performed. 5) In our opinion, Hoke triple arthrodesis can correct any deformity and is particularly suitable in severely deformed rigid feet, since excision and replacement of the head of the talus affords better exposure and mobilization as well as easier set-up of the foot. 6) Whenever necessary, triple arthrodesis was combined with tendo Achilles lengthening, percutaneous plantar fasciotomy, posterior capsulotomy, medial or posteromedial release, subtalar and midtarsal wedge osteotomy, tibiotalar arthrodesis, supramalleloar osteotomy, and transmetatarsal osteotomy, followed by cast wedging or tendon transfers if indicated. 7) There was no nonunion in our cases. Clinically significant skin necrosis and wound sloughing occurred in 8 feet, gross postoperative infection in 2 feet, secondary osteoarthritis of the ankle in 2 feet, significant residual equinus deformity in 8 fret(in seven tendo Achilles lengthening was not done and in the one with tendo Achilles lengthening the deformity had been extreme and rigid), residual varus deformity in 3 feet, and residual valgus in 1 foot. These major complications occurred mostly in older children and adults, in whom deformities were severe and rigid and extensive surgery was necessary in order to achieve adequate correction. In such feet, correction is extremely difficult and greater risks of a variety of complications demand meticulous attention to technical details and postoperative care.

Initial success with total hip arthroplasty on those severely crippled, painful hips in elderly people has prompted its application to a broad variety of conditions; namely, primary and secondary osteoarthritis, rheumatoid arthritis, avascular necrosis of the femoral head, and failed arthroplasties. Some have attempted it on previously arthrodesed hips, while others have successfully treated failed Girdlestone by total hip arthroplasty. To date, however, total hip arthroplasty remains essentially a procedure for older people. It has been greatly emphasized that total hip arthroplasty on 29 cases of residual hips secondary to pyogenic or tuberculous infection occurred during childhood. All were young adults ranging from 17 to 56 years of age, with a mean age of 32. 1 years. None of the hips had active infection at time of operation, although in 2 cases biopsy, at the arthroplasty, revealed chronic granulomatous inflammation. The hips had bony or fibrous ankylosis,or pseudarthrosis with dislocation, and presented marked flexion deformity, bony hypoplasia, limb shortening, and muscle atrophy. In 6 cases, arthroplasty was preceded by preliminary anterior soft tissue release and osteotomy of the ankylosis, followed by skeletal traction. In one case, anterior release through a separate incision was carried out on the same setting prior to arthroplasty. Lateral approach with trochanteric osteotomy was routinely employed, except in two in which the hip was approached posteriorly without trochanteric osteotomy. Trapezoidal-28 prosthesis was used in 17 cases, 5 of which were of short neck, thin stem sized, 7 of which were of medium neck small stem sized. Muller prosthesis was used in 8 cases, 7 of which were of standard neck standard stem sized. One small straight stem Charnley prosthesis failed and was later replaced by a custom-made Charnley stem prosthesis. Two offset bore ovoid cup and Charnley extra-small stem were used. In addition to routine preoperative, intraoperative, and postoperative antibiotics, Kanamycin was mixed to cement routinely. There was no postoperative wound infection. In two cases with presumably healed tuberculosis, infection recurred after arthroplasty. In all the remaning hips, painless serviceable function was restored, especially in view of diverse range of motion in orientals. In the oriental life style, the importance of a mobile hip cannot be overstressed.

Intra-uterine fracture of normal bone is extremely rare. It was reported few cases in the other contries, but it was very rare in Korea. It is difficult to distinguish it from birth fracture and the other fractures or deformities seen at birth. The authors experienced a case of intra-uterine fracture of the femur in the middle third of the shaft, with abundant callus formation in infant without serious injury to the mother.

Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Dignosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

Chondromalacia patella is a symptom complex characterized by aching pain behind the knee cap, retropatella tenderness that is aggravated by the stair climbing. Malalignment is an important factor causing chondromalacia patella. And to recognize it, is important in the diagnosis and treatment. We studied 3 parameters in the chondromalacic knee and nonchondromalacic knee and the following results was obtained. l. In nonchondromalacic knee, the sulcus angle is 141° 7′ and the congruence angle is −5° 1′ 2. In chonduomalacic knee the sulcus sagle is 139° 2′ and the congruence angle is +5° 3′ 3. In the group with abnormal congruence angle, there was much degenerative changes in the patellofemaral joint. So, it can be inferred that chondromalacia is a precursor of the osteoarthritis and the patient with abnormal congruence angle should be treated actively at the early stage if the conservative treatment had failed.

BACKGROUND: The importance of the determination of cell viability has prompted the development of several assays of viability that utilize the exclusion of certain dyes by viable cell membranes. Recently, flow cytometry has been adapted to estimate cell viability by using fluorescent dye which is excluded by living cells on the basis of altered dead cell properties. OBJECTIVE: We have developed a flow Cytometric method for measuring cell viability after staining with propidium iodide (PI) and have compared it with the classical colorimetric method, MTT assay, which is currently widely used in cytotoxicity assays in the research field. METHODS: We performed flow cytometry and MTT assay for the comparison of the sensitivity of the assessment of cell viability. RESULTS: Decrease of cell viability was measured by flow cytometry with the addition of as little as 0.002% Triton-X 100 in comparison to MTT assay which could only reveal a similar decrease of cell viability with the new method to 0.008% Triton-X 100. CONCLUSION: Our results demonstrate this new method to be more sensitive and simple for the assessment of cell viability.

BACKGROUND: We studied the antibiotic sensitivities to the causative microorganisms of acute simple urinary tract infection for recent 3 years. METHODS: We analyzed 112 microorganisms and their antibiotic sensitivities of the 104 patients who were admitted to or visited the Department of Urology, Catholic University St. Marys Hospital and had more than 10cfu/mL on urine culture from June 1996 to January 1999 retrospectively. RESULTS: The chance of gram negative and positive as causative microorganisms was 72.3% and 27.7% respectively. The most common pathogenic microorganisms were Escherichia coli (67.0%) followed by a-hemolytic streptococci, Entercoccus. In gram negative acute UTI, imipenem, sulperanzone showed relatively higher sensitivity, while cotrimoxazole, ampicillin showed relatively lower sensitivity. In gram positive, vancomycin, penicillin showed relatively higher sensitivity, while ampicillin, imipenem showed relatively lower sensitivity. CONCLUSIONS: We consider that gram negative microorganisms, especially E. coli, is the main cause of acute simple UTI. But, we should be concerned about the increase of gram positive organisms and other gram negative organisms besides E. coli. Regarding to the choice of adequate drug in the treatment of UTI, it is necessary to consider the change of pathologic microorganisms.
