PURPOSE: As well as patient survival, the restoration of postoperative function such as ambulation is important in limb salvage operations for treatment of malignant bone tumors involving the proximal femur. The authors analyzed clinical outcomes of limb salvage operations using tumor prostheses for metastatic or primary malignant bone tumors in the proximal femur. MATERIALS AND METHODS: From February 2005 to January 2014, 20 cases (19 patients) with malignant bone tumor involving the proximal femur with pain or complicated pathologic fracture were treated with segmental resection and limb salvage operations with tumor prostheses. Mean age was 63.1 years (range 35-86). Fourteen patients were male and six ones were female. The mean follow-up period was 20 months (1-94 months). There were 15 cases of metastatic bone tumor, 4 cases of osteosarcoma, and 1 case of multiple myeloma. The primary tumors of the metastatic bone tumors included 4 lung cancers, 3 hepatocellular carcinomas, and 3 renal cell carcinomas. Other primary tumors were breast cancer, thyroid cancer, colon cancer, prostate cancer, and malignant spindle cell tumor, each in 1 case. Modular tumor prostheses were used in all cases; (Kotz's(R) Modular Tumor prosthesis (Howmedica, Rutherford, New Jersey) in 3 cases, MUTARS(R) proximal femur system (Implantcast, Munster, Germany) in 17 cases). Perioperative pain was assessed with Visual Analogue Scales (VAS). Postoperative functional outcome was assessed with Musculoskeletal Tumor Society (MSTS) grading system. RESULTS: Out of 20 cases (19 patients), 11 cases (10 patients) survived at the last follow-up. Average postoperative survival of the 9 deceased patients was 10.1 months (1-38 months). VAS score improved from pre-operative average of 8.40 (5-10) to 1.35 (0-3) after operation. Average postoperative MSTS function score was 19.65 (65.50%, 7-28). The associated complications were 2 local recurrences, 3 hematomas, 3 infections, 2 scrotal swellings, and 1 dislocation. There was no case of periprosthetic fracture or loosening. CONCLUSION: Limb salvage operation with tumor prosthesis is an appropriate treatment for early pain reduction and functional restoration in malignant bone tumors in the proximal femur with pain an/or complicated pathologic fractures.

The goals of treatment in the injuries of posterior cruciate ligament(PCL) are restoration of normal tibiofemoral stability and reduction of long term osteoarthrosis of the knee. The purpose of this study is to analyze the factors on posterior stability and functional result after PCL reconstruction. From March 1996 to April 1997, twenty operation on PCL reconstruction were carried out in our hospital. The functional results according to the criteria of the Lysholm knee score and stress radiograph for posterior stability were evaluated. The average functional results evaluated by Lysholm knee score was 87. There was no significant difference in functional result according to selected grafted material, combined knee injury, type of injury and arthrotomy, etc. Difference in posterior tibial translation on average were 2.8mm in acute and 7.7mm in chronic injury. In posterolateral combined injury, average posterior tibial translation in pos- terolateral repair was 3.2mm and in posterolateral reconstruction was 9.4mm. In PCL reconstruction using hamstring with repair of PCL remnant was 2mm. In conclusion, to obtain the good result on posterior sta- bility, early PCL reconstruction using hamstring with repair of PCL remnant, and appropriate treatment on combined posterolateral injury were recommended.

PURPOSE: Bevacizumab has been used as a promising drug for metastatic colorectal cancer in combination with chemotherapeutic agents. However, it has a few serious adverse effects, such as intestinal bleeding or perforation. The purpose of this study is to identify the clinical characteristics of intestinal perforation induced by bevacizumab in colorectal cancer patients.METHODS: From January 2007 to June 2018, a total of 488 patients underwent chemotherapy with bevacizumab for metastatic colorectal cancer. Medical records were reviewed retrospectively.RESULTS: Nine patients (1.8%) were identified with intestinal perforation induced with bevacizumab. The median age was 59 years (range, 36–68 years). The primary tumor site was the sigmoid colon in six patients, the rectum in three patients. The liver was the most common metastatic organ (7 patients). Perforation sites were primary tumor site of the colorectum in four patients and the small bowel in five patients. Intestinal perforation was developed after a median of 3 chemotherapy cycles (range, 1–15 cycles), and a median of 7 days (range, 3–32 days) after chemotherapy. One patient expired due to sepsis.CONCLUSION: Bevacizumab induced intestinal perforation is a lethal adverse effect in patients with colorectal cancers. The characteristics of intestinal perforation varied according to perforation site, previous chemotherapy cycles, and clinical course. Careful monitoring is necessary with the use of bevacizumab in conjunction with chemotherapeutic agents.

PURPOSE: For the past two decades, there has been a significant increase in the prevalence of both asthma and obesity. Obesity may be associated with increasing childhood asthma and atopy. So, we performed this study to know the effects of body mass on bronchial hyperresponsiveness (BHR) and atopy in childhood asthma. METHODS: The subjects were, 340 children aged 6-15 years with asthma, visited the Pediatric Outpatient Clinic. There, their heights and, weights were measured and they underwent, pulmonary function tests (PFT), BHR to methacholine and skin prick tests. After determining body mass index (BMI), they were divided into four groups by BMI percentile curve based on gender and age (underweight < or =15th percentile, normal weight 15.1-85th percentile, overweight 85.1th-95th percentile, obesity > or =95.1th percentile). Atopy, allergen sensitization, BHR, respiratory symptoms, PFT were compared between each group. RESULTS: In all subjects, there were 70 (20.6%) and 73 (21.5%) cases in the overweight and obese groups, respectively. Increasing BMI was significantly associated with a higher prevalence of snoring,(P=0.004) wheezing in the perceding three months (P=0.002) and BHR- positive,(P=0.003) but not atopy.(P=0.075) Among the groups classified by BMI percentile, there were significant differences in FEV1 and FEV1/FVC.(P=0.027, P=0.033) Being overweight and/or, obese were significant risk factor for BHR, though only among females (OR 5.1; 95% CI 1.6-16.5, 4.9; 1.8-13.4) not male (OR 1.1; 95% CI 0.5-2.1, OR 1.7; 95% CI 0.7-2.0). CONCLUSION: Among girls, a higher BMI might be a risk factor for BHR. Higher BMI is not associated with atopy on either boys or girls.

Background: This study compares ultrasound and surgical findings of anatomical variations in de Quervain’s disease. Methods: Seventy-four wrists from patients with unilateral de Quervain’s disease were examined through ultrasonography and surgery. Presence of intracompartment septum, abductor pollicis longus (APL) slips, and selective stenosis were verified by both methods. Two orthopedic surgeons assessed ultrasound findings for intra- and interobserver reliability. Results: Amongst 74 participants (43 women and 31 men), 60.8% had a complete septum, 31.1% had an incomplete septum, and 8.1% had no septum; 70.3% had multi-slip APL and 66.2% had extensor pollicis brevis stenosis. Surgical and ultrasonographic findings displayed a high level of sensitivity and specificity. Intraobserver reliability was high, and interobserver reliability was substantial. Conclusions The study confirms ultrasonography’s reliability in identifying anatomical variations in de Quervain’s disease, with high sensitivity, specificity, and substantial intra- and interobserver reliability, emphasizing its usefulness in preoperative assessment and planning.

Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleeding from the orifice of the appendix. We performed a laparoscopic appendectomy. Microscopically, dilated veins were found at the submucosal layer of the appendix. The patient was discharged uneventfully. Although lower gastrointestinal bleeding of appendiceal origin is very rare, clinicians should consider it during differential diagnosis.
