PURPOSE: To evaluate the results of femoral component revision with proximal modular prosthesis in 32 hips. MATERIALS AND METHODS: Thirty-two hips of thirty patients, which were revised with proximal modular femoral component due to aseptic loosening, were investigated. These patients were followed radiologically and clinically at least for two years. RESULTS: These patients were followed for an average of 2.8 years. Complications included four intraoperative femoral fractures (three at proximal, one at distal), two progressive subsidence, one infection, and one non-union and one fibrous union of the greater trochanter. Of the 32 hips, three hips were re-revised due to progressive subsidence in two and recurrent dislocation in one. Acute postoperative infection developed in one patient, who suffered from diabetes mellitus. Radiographically, satisfactory results were noted in 27 (84.7%) of 32 hips at the latest follow-up. Harris hip score was improved from an average of 47 points to an average of 93 points. CONCLUSION: This study provides encouraging results in femoral component revision with proximal modular prosthesis.

Heat stroke, a medical emergency, occurs when the body's thermal regulation is upset and unable to dissipate adequate amounts of heat with a rise in body temperature. It is characterized by hyperyrexia, with a core temperature of 40degrees C or more, hot dry skin, and central nervous system disturbance and usually results in rhabdomyolysis and multiorgan failure. Our case, a 43-year-old healthy male, was caused by a marathon, half course, on a sunny day in late summer. He suddenly fell down on the road and was delivered to a nearby hospital, where a seizure developed. He was transfered to our hospital and then displayed Central Nervous System disturbance, hot dry skin, acute liver failure, rhabdomyolysis, anuric acute renal failure, and disseminated intravasculular coagulopathy. He was treated with general supportive care and hemofiltration. Despite the aggressive management, he died of shock on the fifth day after admission.

Gestational trophoblastic tumors including choriocarcinoma bave become one of the most curable human malignancies with an overall cure rate exceeding 90%. Although systemic chemotherapy is the initial treatment for chorio- carcinoma, some patients with chemotherapy-resistant choriocarcinorna can be treated by integration of cbemotherapy, surgery and radio- therapy. We report two cases of persistent localized choriocarcinoma which was treated by surgical intervention.

BACKGROUND: The purpose of this study was to analyze the endotracheal intubation cases performed in the emergency department. METHODS: We investigated retrospectively 326 cases of endotracheal intubation performed in the emergency department of a tertiary care center from April 1, 1998 to March 31, 1999. We focused on operators, medications used, its success rate and immediate complications, and the relationship between its success rate and medications. RESULTS: Of 326 consecutive intubations, 193 patients(59.2%) were done by emergency medicine residents or attending physician. While 320 patients(98.2%) were successfully intubated, 6 patients could not be intubated and 2 patients underwent tracheostomy. Of 50 cases of intubations(15.3%) attempted with paralyzing agents, 48 cases were done with succinylcholine and 46 cases underwent by emergency physicians. Intubations with neuromuscular paralysis resulted in high success rates at the first attempt. Of 55 immediate adverse events were encountered in 47 patients(desaturation=17, bronchial intubation=15, hypotension=8, bradycardia=4, cardiac arrest=2, others=5). CONCLUSION: At this institution, paralyzing agents were used infrequently, but almost all of them were used by emergency physicians.

Complications from hysteroscopy are relatively rare events. They occur more frequently with operative hysteroscopy than with diagnostic hysteroscopy. Air embolism is a rare but devastating complication of hysteroscopy that rightly receives attention as a frightening, sudden, and potentially fatal hazard in otherwise healthy women. We experienced one case of air embolism during diagnostic hysteroscopy for abnormal uterine bleeding under general anesthesia. Early diagnosis and prompt treatment seem to be the keys to prevention of catastrophic outcomes and the hysteroscopists must understand the pathophysiology of air embolism to prevent, diagnose, and manage this potentially disastrous problem effectively.

Teratoma is one of germ cell tumor, common neoplasm in women of reproductive age, but it can arise at any age. Its malignant transformation is rare, less than 2%, frequently at older age. Nearly all the cases are squamous, sarcomatous and adenomatous transformation. Here we present a case of mixed transformation, adeno-squamous cell carcinoma with brief review of the concerned literature.

BACKGROUND/AIMS: The clinical usefulness of nasogastric tube insertion in poisoning patients is controversial. This study compared the incidence of aspiration pneumonia between patients with or without nasogastric tubes. METHODS: We retrospectively reviewed the clinical reports of poisoning patients seen from January 2006 to December 2007. We classified the patients into groups with and without nasogastric tube insertion and evaluated the incidence and risk factors of aspiration pneumonia. RESULTS: Ultimately, 63 patients were included. The incidence of aspiration pneumonia was higher in patients with nasogastric tube insertion than in patients without nasogastric tube insertion (conscious patients: 58.8% vs. 11.8%, p=0.010; unconscious patients: 72.2% vs. 27.3%, p=0.027). Nasogastric tube insertion was a significant risk factor for developing aspiration pneumonia (odds ratio 3.54; 95% confidence interval 1.74~12.34). CONCLUSIONS: Nasogastric tube insertion did not prevent aspiration pneumonia, but was a risk factor. The results have implications in the development of a hypothesis about why a nasogastric tube increases the risk of aspiration pneumonia. This study has important limitations stemming mostly from other compounding factors and its retrospective design.

The aneurysm arising from fenestrated proximal anterior cerebral artery (ACA) is considered to be unique. The authors report a case of a 59-year-old woman who presented with a subarachnoid hemorrhage (SAH) secondary to a ruptured aneurysm originating from the fenestrated A1 segment of right ACA. The patient had another unruptured aneurysm which was located at the right middle cerebral artery bifurcation. She was successfully treated with surgical clipping for both aneurysms. From the previously existing literatures, we found 18 more cases (1983-2011) of aneurysms associated with fenestrated A1 segment. All cases represented saccular type of aneurysms, and 79% of the patients had SAH. There were three subtypes of the fenestrated A1 aneurysms depending on the anatomical location, relative to the fenestrated segment. The most common type was the aneurysms located on the proximal end of fenestrated artery (82%). Azygos ACA and hypoplastic A1 were frequently accompanied by the aneurysm (33% and 31%, respectively), and multiple aneurysms were shown in three cases (16%). Considering that fenestrated A1 segment is likely to develop an aneurysm, which has high risk of rupture, early management may benefit patients with aneurysms accompanied by fenestrated proximal ACA.

PURPOSE: Axillary node involvement is the single most important prognostic variable in patients with breast cancer. If axillary lymph node status of breast cancer patients could be accurately predicted from basic clinical information and from characteristics of their primary tumors, many patients could be spared axillary lymph node dissection. With the availability of numerous histologic prognosticators and new immunochemical prognostic indicators, it is reasonable to reconsider the necessity of axillary node dissection for lesions more advanced than duct carcinoma in situ. MATERIALS AND METHODS: Six hundred fifty-six patients with Tl invasive breast cancer were evaluated. All the patients underwent axillary dissection, and the pathologic status of the nodes was known. The parameters of the primary tumor in this study were age, size, family history, tumor palpability, nuclear and histological grade, hormone receptor status, lymphatic vessel invasion (LVI), and various tumor markers (bc1-2, cathepsinD, c-erbB2, E-cadherin, p53). RESULTS: Approximately 31% of the 656 patients with Tl breast carcinoma had axillary node metastasis. Four factors were identified as significant predictors of node metastasis: age 35 or less (p=0.01), lymphatic vessel invasion (p < 0.01), tumor palpability (p=0.02), and tumor size (p<0.01). However, independent predictors of lymph node metastasis in the multivariate logistic regression analyses were tumor size (p=0.04) and LVI (p=0.03). CONCLUSION: Characteristics of the primary tumor can help assess the risk for axillary lymph node metastases in Tl breast cancer. Selected patients who have 1cm or less without lymphatic vessel invasion are considered to be at minimal risk of axillary node metastasis and might be spared routine axillary dissection.
