Fractures of the tibia are frequently encountered in mordern civilized society. Especially, those in distal 1/3 of the tibia have so many problems, such as angular deformity, osteomyelitis and nonunion because of anatomically scanty soft tissue. Many modalities of the treatment of fracture of distal 1/3 of the tibia were introduced. Among them, interlocking IM nailings were considered as one of the best modality. But, in interlocking IM nail, reaming of the medullary canal which destroys the endosteal circulation and causes thermal necrosis of the inner aspect of the cortical bone results in delayed union. And also, procedure for distal screw fixation is difficult and time-consuming. As for using flexible IM nails for fractures of distal 1/3 of the tibia, it was considered as not so satisfactory method due to lack of stability of fixation. However, the stability of fixation can be strengthened with fanning of the nails in distal fragment, using more than 3 nails and delay the protected weight bearing. Authors studied 25 cases of fractures of distal 1/3 of the tibia treated with closed flexible IM nailing at Sung Ae General Hospital, from July., 1987 to July., 1989, and obtained following results: 1. Among 25 cases, 4th decades were most common and males were more commonly involved. 2. Traffic accidents were the most common causes of injury and majority of 16 open fractures and 19 comminuted fractures, were caused by high energy mechanism. Among open fractures, type II were most common. 3. Two angular deformities less than 10 degrees, one proximal migration and one checkrein deformity were observed as complications, but, no clinically significant complications were noted. 4. The time for radiological union were 14.5 weeks in group without fibular fracture and 15.1 weeks in group with fibular fracture, and 14.0 weeks in closed fracture group and 17.2 weeks in open fracture group, and average in 15.6 weeks.

PURPOSE: To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. MATERIALS AND METHODS: The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. RESULTS: Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. CONCLUSION: Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

Ferrocholinate, choline citrate iron salt is a new chelate iron which is synthesized by reacting ferric hydroxide with choline dihydrogen citrate. Ferrocholinate is used in the prevention and treatment of microcytic, hypochromic anemias due to iron deficiency. Ferrocholinate does not release high concentrations of free ionic iron in the gastrointestinal tract and clinical reports, although limited, seem to indicate that this drug is better tolerarated than is ferrous sulfate or ferrous gluconate. Ferrocholinate : syrup was administered to 19 patients of iron deficiency anemia. Ferrocholinate was administered orally. Therapeutic dosage was 1.2cc/kg (elementary iron 6mg/kg) divided three times daily. The results were obtained as follows. (Table 1) 1) In this clinical trials, the over-all effective rate was 84.2% 2) There was no effect on 3 cases who have combined with severe infection and congenital heart disease. 3) Of the 19 patients, 2 patients complained transient nausea and 1 patient mild diarrhea. These symptoms, however, disappeared along with continued therapy.

PURPOSE: The aim of this study was to identify clinical predictive factors for tumor response after preoperative chemoradiotherapy (CRT) in rectal cancer. MATERIALS AND METHODS: The study involved 51 patients who underwent preoperative CRT followed by surgery between January 2005 and February 2012. Radiotherapy was delivered to the whole pelvis at a dose of 45 Gy in 25 fractions, followed by a boost of 5.4 Gy in 3 fractions to the primary tumor with 5 fractions per week. Three different chemotherapy regimens were used (5-fluorouracil and leucovorin, capecitabine, or tegafur/uracil). Tumor responses to preoperative CRT were assessed in terms of tumor downstaging and pathologic complete response (ypCR). Statistical analyses were performed to identify clinical factors associated with pathologic tumor response. RESULTS: Tumor downstaging was observed in 28 patients (54.9%), whereas ypCR was observed in 6 patients (11.8%). Multivariate analysis found that predictors of downstaging was pretreatment relative lymphocyte count (p = 0.023) and that none of clinical factors was significantly associated with ypCR. CONCLUSION: Pretreatment relative lymphocyte count (%) has a significant impact on the pathologic tumor response (tumor downstaging) after preoperative CRT for locally advanced rectal cancer. Enhancement of lymphocyte-mediated immune reactions may improve the effect of preoperative CRT for rectal cancer.

The possible role of collagenase in the development of corneal ulcers has been intensively studied and collagenase inhibitors have been successfully used to control some corneal ulcers. They are cysteine, EDTA, proteoglycan, serum, and medroxyprogesteron, However, most of them are limited in clinical use because of their toxicity and instability except serum, which is not toxic to the host. We carried out an experiment with serum upon alkali-burned rabbit cornea. Serum has potent anticollagenase effect, and prevents corneal ulceration.

A case of Wegener's granulomatosis is described, with special attention focused on the typical histologic findings and involvement of both middle ear and lung. The patient is a 37-year-old man presented with four-month history of cough and sputum. He had a past history of surgery of both ears because of otitis media followed by left facial palsy. Chest radiographs showed variable sized ill defined nodules in both lower lobes with internal airspace consolidation. Histologic preparations of the open lung biopsy specimens demonstrated a diffusely scattered palisading micro and macrogranulomas with central focus of neutrophils and necrotic collagen surrounded by histiocytes, histiocytic giant cells. Fibrinoid necrosis involved blood vessels and lung parenchyma. Chronic inflammation, diffuse granulation tissue formation and irregular fibrosis are also found in the lung parenchyma. The histologic findings of middle ear which was previously biopsied showed scattered palisading ill defined microgranulomas mixed with fibrotic tissue.
