Hepatoid carcinoma is a rare type of malignant tumor resembling hepatocellular carcinoma that arises in extrahepatic sites.(stomach, lung, ovary, pancreas, bladder and renal pelvis). Hepatoid carcinoma of the ovary is an extremely rare ovarian tumor, first described by Ishikura and Scully in 1987. Histologically it is important to differentiate this entity from other oxyphil tumors of the ovary as it requires aggressive treatment. We have experienced a case of hepatoid carcinoma of the ovary in 69-year-old postmenopausal woman, who has been treated with operation and adjuvant Taxol - cisplatin chemotherapy. We present this case with brief review of literatures.

The ideal breast reduction should create beautiful breasts with limited scars. Unfortunately, no surgeon has ever been able to produce such a result. Most recent breast reduction techniques tend to produce minimal breast scars and avoid the classic inverted-T incision. The vertical mammaplasty can be used in mild to moderate cases of breast reduction, producing consistently good, stable results with limited scars. This technique uses adjustable preoperative markings, an upper pedicle for the areola, and a central breast reduction with limited skin undermining. The shape of the breast is created by suturing of the gland and does not rely on the skin. The adjunctive use of liposuction in fatty breasts can be considered safe and efficient. We have performed reduction mammaplasty using the vertical mammaplasty technique in 12 patients. Overall number and extent of complications were small, and patient satisfaction was high for this procedures. The advantages of vertical mammaplasty technique compared with other methods are as follows ; 1. The markings are adjustable to nearly all patients. 2. Stable contours are produced because the gland is strongly sutured. 3. Few postoperative complications occur. 4. Limited scars(only vertical scars) are created 5. The procedure is easy to learn and perform.

Since 1981 there have been many clinical and experimental reports of venous skin flap, which was nourished solely by venous blood, or by arteria1 blood flowing through the venous network. But, the mechanism of survival has not been completely understood. Unfortunately, partial flap necrosis and unstable postoperative recovery course make surgeons hesitant in choosing the venous flap. In order to increase the survival of a venous flap, surgical delay procedure or increasing the number of draining veins have been successfully tried. Historically, tissue expansion has the same effect on skin vascularity as delaying the area The increase in the caliber of the blood vessels and adequate neovascularization of the expanded tissue can increase the size and vascularity of the flap while allowing primary closure of the donor defect. In order to investigate the survival pattern of expanded arterialized venous flap, the author conducted the following study. The arterialized venous flaps were divided into control and two experimental groups. The conventional nonexpanded arterialized venous flap of 5x5 cm in size was used as control group On experimental group I, preoperative tissue expansion was performed during 3 weeks, and then arterialized venous flap with the same size was made. On experimental group II, expanded arterialized venous flap with 10x10 cm in size was made. The mean survival rate of control, experimental group I and II was 81.2%, 98.8% and 99.1%, respectively. The angiogram of expanded flap showed dilatation of the vessels and neovascularization with tortuous vessels to the peripheral area of the flap. In conclusion, the survival of expanded arterialized venous flap was superior than that of conventional arterialized venous flap. The expanded venous flaps appear to be useful in producing large flaps, in decreasing marginal necrosis of the flap as well as minimizing donor defect.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

BACKGROUND: To evaluate the role of free fatty acids on the ischemic myocardium, influences of various free fatty acids upon transmembrane action potential and ATP-sensitive K+(KATP) channel activity were examined in the ventricular myocardium and single cardiac myocytes. METHODS: KATP channel activities were measured in the enzymatically (collagenase) isolated single rat ventricular cardiac myocytes by the method of the excised inside-out and the cell-attached patch clamp, and transmembrane action potentials were recorded using the conventional 3M-KCl microelectode techniques in the rat ventricular myocardium. RESULTS: Free fatty acids [FFAs; arachidonic acid (AA), linoleic acid (LA) and lysophosphatidylcholine (LPC)] reduced the KATP channel activity in a dose-dependent manner in the inside-out patch, and 50%-inhibition concentrations (IC50) were 88 +/- 11.2, 49 +/- 12.5, and 188 +/- 17.4 M respectively. Both frequency of channel opening and the mean open-burst duration were markedly decreased, but the amplitude of single channel currents were not changed by the FFAs. AA (50 micrometer) and LPC (50 micrometer) did not affect the dinitrophenol (DNP, 50 micrometer)-induced KATP channel activity, whereas LA (50 micrometer) had a tendency to reduce the activity. The channel inhibition effects by 10 micrometer AA in the inside-out patch were significantly augmented by diclofenac (10 micrometer), but was not changed by nordihydroguaiaretic acid. FFAs never stimulated KATP channel activity, even in the inside-out patch where KATP channel activity reduced in the presence of internal ATP (100 micrometer). Time for 90% repolarization (APD90) significantly increased during superfusion of the FFAs, to 22 (50 micrometer AA), 24 (50 micrometer LA), and 18 (50 micrometer LPC) % from those of the contol at the time of 10 min superfusion, but the other action potential characteristics were not changed by the FFAs. AA (10 micrometer) attenuated cromakalim (10 micrometer)-induced APD90 shortening effects. CONCLUSION: It was inferred that FFAs inhibit the KATP channel activity directly by themselves and/or indirectly by their metabolites in the rat ventricular cardiomyocytes, and therefore, duration of action potential lengthens to be a burden over the ischemic myocardium accounting for the injury of myocardium at the late stage of ischemia.
