The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern and predominantly fibroblastic appearance. It was postulated that they were derived from histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized to be the most common sarcoma in the soft tissue of late adult life which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs, however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes the clinical courses, characteristics and pathologic aspects with review of the related literatures.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

We had two cases of hepatitis developing after surgery. Case 1. A 47 year old male underwent surgery for amputation of the lower leg under enflurance anesthesia. Preoperative liver function test were slightly abnormal. On the 25th portoperative day, serum transaminases were elevated and the A/G ratio was reversed. On the 65th postoperative day, the liver function tests returned to near normal leve. Case 2. A 37 year old male underwent the first surgery for reduction of a pateliar fracture under spinal anesthesia. Preoperative serum transaminages were elevated and other laboratory findings at normal levels. On the 20th postoperative day serum transaminases were more elevated and on the 120th postoperative day, ti became normal again. This patient underwent the second surgery for removal of a K-wire under enflurane anesthesia and afterwards hepatitis recurred. On the 60th 2nd postoperative day LEFs became nearer to normal level and he was discharged in good health. Possible causes of the hepatitis in these cases were considered to be the preoperative liver disease, blood transfusion, the stress of the surgery and anesthesia.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

The increasing use of intravenous polyethylene catheters has led to a growing incidence of accidental catheter breakage and migration of fragments into the central vascular system usually in the inferior vena cave, the right atrium, of the pulmonary artery. The most common complications were formation of a thrombus in the area of the foreign body, infection with endocarditis, and perforation of the heart. And so obviously the polyethylene catheter must be removed. In 1967, Massumi and Ross et al have been successful in removing a catheter fragment from the right atrum percutaneously with a snare device. With some modification as suggested by Curry, method of retrieving fragments of polyethylene catheters from the heart without chest surgery utilize wire snares or endoscopic forceps. This report describe the technique and its use in successfully managing these complications in four consecutive cases.

Toxoplasmosis is a ubiquitous protozoan infection caused by coccidian Toxoplasma gondii. In an immunocompetent host, the primary infection is generally oligosymptomatic and self-limiting. Fewer than 10% of infected subjects are symptomatic, with lymphadenopathy as the most frequent clinical finding. Here, two cases of Toxoplasmic lymphadenitis are reported for otolaryngologists to consider the clinical findings and natural history aspects of this infection.

The major risk factors for diabetics undergoing surgery are the end-organ diseases associated with diabetes. Autonomic neuropathy is relatively common in diabetic patients and associated with an increased risk of perioperative cardiovascular instability. We experienced a case of severe bradycardia and hypotension during general anesthesia for subtotal gastrectomy in a 59 year-old male diabetic patient. Anesthesia was induced with thiopental and vecuronium, and was maintained with nitrous oxide, oxygen and enflurane. Five minutes after induction, severe bradycardia and hypotension developed without specific events. The bradycardia was unresponsive to intravenous atropine and ephedrine, but the blood pressure was restored by administration of ephedrine. During operation his blood pressure was maintained in normal range but the bradycardia was not restored by additional administration of atropine. Postoperatively, myocardial infarcton was ruled out. The test performed after operation suggested that his cardiovascular autonomic nervous system was severely impaired. We think that cardiovascular autonomic dysfunction should be evaluated during preoperative period to plan the anesthetic management and to prevent severe cardiovascular complications in diabetic patients.

The diagnostic possibility and the incidence of ectopic pregnancy are increasing due to several factor. Furthermore, radioimmunoassay of serum β-HCG and US make it possible to diagnose early before the tubal rupture. A conventional surgical approach has been considered as a choice of treatments. Until recent years, however, surgery may have considerable risk of infertility and sugical hazard. In view of the natural tendency of some ectopic pregnancies to terminate in tubal abortion or complete resorption, we tried to cure ectopic pregnancy with nonsurgical transcervical intervention. Five of 8 patients with unruptured tubal pregnancies, it was possible to inject PGF2a into the tubes or gestational sac. 4 of them were ended up with satisfactory reduction of serum β-HCG level and improvement of symptoms & signs. In only one patient, β-HCG level remained a high level continuously, so salpingectomy was done. As a result, we consider that fluoroscopy-guided transcervical interventional procedure is a useful treatment modality for early unruptured ectopic pregnancy.
