Clinical Outcome of Surgical Treatment of Distal Humerus Intercondylar Fractures Through the Transolecranon Approach Combined with Anterior Transposition of the Ulnar Nerve

PURPOSE: To analyze the clinical outcomes of surgical treatment of distal humerus intercondylar fractures through the transolecranon approach combined with anterior transposition of the ulnar nerve. MATERIALS AND METHODS: Eight patients who had distal humerus intercondylar fractures were included in this study and underwent operative treatment through the transolecranon approach for sufficient operative field with anterior transposition of the ulnar nerve and fixed with reconstruction plate. RESULTS: The results were evaluated using Riseborough and Radin rating criteria. Seven cases of eight cases were achieved good results with flexion contracture less than 30 degrees and forward flexion more than 115 degrees. However, one case was acheived poor result with 40 degrees of flexion contractue and 70 degrees of forward flexion. There were no the compressive ulnar neuropathy. CONCLUSION: We found the transolecranon approach and anterior transposition of the ulnar nerve a viable option for surgical treatment of the distal humerus intercondylar fractures

The Clinical Results in Compression Plate Fixation with Autogenous Cancellous Bone Graft for Humerus Diaphyseal Nonunion

PURPOSE: A The purpose of this retrospective study was to evaluate the results of compression plating and autogenous iliac bone graft in the management of humeral diaphyseal nonunion. MATERIALS AND METHODS: Twenty patients who underwent the surgical treatments between May. 1998 and May. 2002 were included in this study. Nine of them are males and the others are females. The average age of them, when they was on operation, was 45 years. The symptoms lasted 23 months on average. They have been followed up for 33 months at an average. Treatment of nonunion consisted of resecting the atrophic nonunion, shortening the bone, apposing bleeding diaphyseal surface. Rigid fixation was then achieved using a compression plate and autogenous bone graft. RESULTS: Solid bony union was achieved in all patients. In one patient, the bone was not healed at the first operation of plating and autogenous bone graft, but achieved union after the use of intramedullary nailing. In another patient, because of infected nonunion, we achieved union after several surgical debridement and stabilization by internal fixation. CONCLUSION: This study documents that compression plate fixation with autogenous cancellous bone graft is a viable option with predictable and satisfactory results for humerus diaphyseal nonunion.

A Case of Placental Site Trophoblastic Tumor / 대한산부인과학회잡지

Placental site trophoblastic tumor(PSTT) is a rare form of gestational trophoblastic disease. This rare tumor has the potential for metastasis and death. The average age at onset of PSTT is 28 years, and the second believed to be postmenopausal at the time of diagnosis. The most common presenting complaint is amenorrhea or abnormal vaginal bleeding and rare complaints are virilization, nephrotic syndrome, uterine rupture, etc. The treatment of choice is surgical removal of the tumor, that is total abdominal hysterectomy with both salpingo-oophorectomy. We present a case of placental site trophoblastic tumor associated with spontaneous uterine rupture that is rare complication with a brief review of literature.

A Case of Impetigo Herpetiformis during Pregnancy / 대한산부인과학회잡지

Impetigo herpetiformis is a rare pustular eruption that may be seen in late pregnancy. It is associated with severe maternal and fetal complications in case of misdiagnosis and delayed treatment. The patient was a 25-years-old multigravida with psoriasis in her past history. At 20weeks gestation, she had been developed erythematous scaly annular patchs with papules and pustules on inner thigh. At 37weeks' gestation, the patient was suffered from a severely pruritic pustular rash with fever and leukocytosis. The skin of the affected areas was biopsied and showed intraepidermal pustular abscess with a neutrophilic infiltrate. Treatment commenced with intravenous fluids, antibiotics, systemic prednisone, steroid creams, and phototherapy(UVB) under the careful fetal well being monitoring. Cesarean section was done due to fetal distress, and a normal healthy male infant was delivered, following which the patient's condition improved rapidly.

The Effect of Amitriptyline on Chloramphenicol: Induced Insomnia in Rats / 신경정신의학

OBJECTIVES: Several studies have shown that administration of antibiotics decreased sleep amount as well as bacterial colony numbers in rats. It is well known that antidepressants decrease rapid eye movement(REM) sleep and increase slow wave sleep(SWS) in both human and animal studies. However, little is known to date about the effects of antidepressant on antibiotic induced insomnia in rats. Therefore the authors studied the effects of amitriptyline on chloramphenicol induced insomnia in rats. METHODS: The Sprague-Dawley strain rats were divided into control(N=6) and experimental group (N=5). The sleep-wake activity was recorded continuously for consecutive three days(baseline, day 1 and day 2). On day 1 both groups were intraperitoneally injected with chloramphenicol 150mg/kg. On day 2 the control group was intraperitoneally injected with chloramphenicol 150mg/kg only, whereas experimental group was injected with amitriptyline 12mg/kg and chloramphenicol 150mg/kg. RESULTS: 1) Chloramphenicol administration decreased dark period SWS and total REM sleep. 2) Amitriptyline administration increased total SWS and dark period SWS as well as decreased total wakefulness and dark period wakefulness. There was a decrease of REM sleep in the first 3 hours of light period, whereas a tendency of increase of REM sleep around the end of dark period. CONCLUSION: From the above results, it is concluded that amitriptyline may be effective to reverse chloramphenicol induced insomnia in rats. Furthermore, chloramphenicol induced insomnia in rat could be a useful model for insomnia studies in the future.

Localized Pigmented Villonodular Synovitis of the Posterior Compartment of the Knee: A Case Report / 대한정형외과학회잡지

Localized pigmented villonodular synovitis is a monoarticular proliferative condition that may affect any joint but is frequently found in the knee. The locaiized form was less frequent than the diffuse one. The estimated frequency of localized pigmented villonodular synovitis among patients performed an arthroscopic procedure was known one case lor each 2,500 cases. Previous reports pointed that the lower recurrence rate after the arthroscopic excision for localized form. We also experienced a case of localized pigmented viilonodular synovitis located at the posterior compartment of the knee, so we report this case with review of literatures.
