Island flaps have been widely used for the management of soft tissue defects in reconstructive surgery. The necrosis of the flap has been a catastrophe in clinical fields. It is well known that revascularization to the flap after ligation of its pedicle comes from the recipient bed and flap margins. The authors investigated the effects of the ischemic recipient bed on island flap survival after the ligation of its pedicle in the rats. One hundred and thirty inferior epigastric island flaps were divided into three groups (Group I, Group II, and Group III) according to the degree (0%,20%, and 60%) of interruption of contact of flap with the recipient bed, respectively. In Group I,the vascular pedicles were ligated before and on the 0, 2nd, 3rd, 4th and 5th days after flap elevation, and in Group II & III, the vascular pedicles were ligated on the 2nd, 3rd, 4th and 5th days after flap elevation. Flap survival was assessed on the 3rd day after pedicle ligation. Microangiographic studies were also performed on the 3rd day after pedicle ligation to study revascularization within the flap and the change of blood vessels around the flap margins. The results were as follows: 1. Flap survival was increased significantly in the flaps with pedicle ligation on the 4th and 5th postoperative days compared to those at the 2nd and 3rd postoperative days. 2. From the 3rd postoperative day, flap survival was not influenced significantly by the degree of limited bed contact and the date of pedicle ligation. 3. In spite of limited bed contact, the flap will likely survive with abundant revascularization from the flap margins. In conclusion, the flaps with limited bed contact were revascularized significantly from the flap margin by the 3rd postoperative day.

A 72-year-old woman developed pruritic erythematous patches on sun-exposed areas for 2 months following treatment with hydrochlorothiazide (Dichlozid) for hypertension. A phototest revealed a decreased minimal erythemal dose to UVA (MED(UVA)=2 J/cm²). A photopatch test with 0.5%, 1%, and 5% hydrochlorothiazide ointment revealed no response. Two weeks after discontinuation of hydrochlorothiazide, the skin lesions improved with complete loss of photosensitivity without any therapy. At that time, an oral provocation phototest with hydrochlorothiazide was performed and it showed a decreased MED to UVA (MED(UVA)=2 J/cm²).

Acute posterior multifocal placoid pigment epitheliopathy(APMPPE), first described in 1968 by Gass, is chracterized by rapid loss of central vision secondary to multifocal, yellow-white placoid lesions at the level of the pigment epithelium and choroid and significant visual improvement after spontaneous resolution of the active lesions within several weeks or months. Fluorescein angiography shows chracteristically that the chtoidal fluorescence is not visible at the site of acute lesion in the early arterial and arteriovenous phases and become hyperfluorescent due to staining of the lesions in the late venous phases. We experienced a case of acute multifocal placoid pigment epitheliopathy in 26 years old female patient occurring in both eyes.

7.A Case of Sepsis and Acute Renal Failure Associated with Salmonella Enterocolitis.

Salmonella infection can cause an asymptomatic intestinal carrier state or clinical diseases such as enterocolitis presenting abdominal pain, fever, vomiting, or diarrhea. Salmonella usually invades Peyer's patch of terminal ileum or ascending colon. Sepsis is not common and acute renal failure secondary to rhabdomyolysis is rare. The causes of rhabdomyolysis are trauma, excessive exercise, alcohol, seizure, metabolic abnormality, and infection. Infections account for less than 5% of the reported causes of rhabdomyolysis and resulting acute renal failure. The mechanisms underlying rhabdomyolysis due to infection are direct muscle invasion, toxin production, and nonspecific effects that can occur with infections such as fever, dehydration, acidosis, and electrolyte imbalance. We report a case of sepsis and acute renal failure secondary to rhabdomyolysis associated with Salmonella infection.

A patient with extraskeletal cervical epidural Ewing's sarcoma who presented with cervical radiculopathy is reported. A 58-year-old woman presented with right posterolateral neck pain and upper extremity radiculopathy. The computed tomography myelography showed epidural and paravertebral masses on right side, with widening of the ipsilateral neural foramina at the C2-C3 level. On magnetic resonance images, the mass was isointense to soft tissue on T1-weighted images, hyperintense on T2-weighted images, and showed diffuse enhancement on GdTA enhanced T1-weighted images. The staged, combined posterior and anterior approach were done and the tumor mass was subtotally removed. During postoperative adjuvant chemotherapy with Cytoxane, Adriamycin, Vincristine, Prednisolone regimen, the patient died of severe compression of upper cervical cord by recurrent, extended tumor mass in the spinal canal.

BACKGROUND: Cardiopulmonary bypass during open heart surgery causes systemic inflammatory respose. IL-10 is an anti-inflammatory cytokine that inhibits inflammatory process and protects organ function by down regulation of pro-inflammatory cytokine release and maintenance of blood level balance with pro-inflammatory cytokines. MATERIAL ateial and Method: Plasma IL-10 levels were measured and analyzed in 22 patients who underwent open heart surgery (11 cases of coronary artery bypass graft, 11 cases of valve replacement) under cardiopulmonary bypass since 1988 January to July at Department of Thoracic and Czardiovascular surgery, Yeungnam University Hospital. 1g of methylprednisolone was administrated to thirteen patients randomly. Blood samp.es were taken and collected at the time of induction of anesthesia, 10 min before cardiopulmonary bypass, 10 min after starting of CPB, 10 min aftr aortic cross clamping, 10 min after ACC release, and 10 min, 2 hours, and 5 hours after CPB respectively. The plasma levels of IL-10 were determined by enzyme-linked immunosorbent assays (ELISA). Wilcoxon-Raule Sum test was used for statistical analysis. In all 22 patients, cardiopulmonary bypass time was used for statistical analysis. In all 22 patients, cardiopulmonary bypass time was 171+/-41.4 min and aortic cross clamp time was 118+/-36.5 min. Peak IL-10 level was achieved at 10 min after ACC (361.0+/-52.81pg/ml) and was decreased sharply at 2 hours after CPB. Peak IL-10 level was correlated positively with aortic cross clamp time (p=0.011); however, it did not correlated with bypass time (p=0.181). In valve replacement group, mean IL-10 level at peak point was 567.89+/-107.69 pg/ml and was significantly higher than that of coronary artery bypass group (205.67+/-192.70 pg/ml) (p<0.001). ACC time in valve replacement group was significantly longer than that of coronary artery bypass group (p<0.01), however, bypass time was not (p=0.212). Thirteen patients with steroid pretreatment before starting of CPB showed relatively higher plasma IL-10 level than in control group, however, no statistical significance was noted (p=0.19). CONCLUSION: plasma level of IL-10 was increased in association with cardiopulmonary bypass and revealed peak at 10 min after ACC release. IL-10 level was correlated positively with ACC time. Therefore, systemic inflammatory respeonse in association with cardiopulmonary bypass could be decreased by reducing ACC time during cardiac surgery.
