The effect of taurine on flap perfusion and viability in random pattern flaps in rats.

BACKGROUND: In present study, the effect of taurine on flap perfusion and viability was examined using the modified random pattern dorsal flap model (DFM). MATERIALS AND METHODS: Eighteen rats were included and divided equally (n=9) to taurine treatment and control groups in this study. Taurine treatments were given orally at a dose of 100 mg/kg/day. Taurine group received taurine, starting 3 days before the operation till the postoperative 3rd day. Angiographic images were recorded when the flaps were sutured back and on postoperative 5th and 7th days. Necrosis calculations were made with all the images obtained by the digital camera and the indocyanine green angiography. Fluorescence intensity, fluorescence filling rate and flow rate of DFM were calculated by the SPY device and the SPY-Q software. All flaps were analyzed histopathologically, also. RESULTS: Perioperative taurine treatment significantly reduced necrosis rates and increased the fluorescence density, the fluorescence filling rate and the flap filling rates in the DFM (p<0.05). Reduced amounts of necrosis, ulcer and polymorphonuclear leukocyte supported the beneficial effect of taurine histopathologically (p<0.05). CONCLUSIONS: Taurine may be used as an effective medical agent for prophylactic treatment options in flap surgery.

A rare giant sarcoma of the chest wall: Undifferentiated pleomorphic sarcoma.

Undifferentiated pleomorphic sarcoma or, as formerly called, malignant fibrous histiocytoma is a type of sarcoma which originates from fibroblast and histiocytic cells. It is the most common type of sarcoma among all soft tissue sarcomas in adults. Its most common site is the lower limb, followed by the upper limb and the retroperitoneum. It is rarely encountered on chest wall. In the differential diagnosis of masses on chest wall, it is important to consider undifferentiated pleomorphic sarcoma in surgical planning. In this article, we report a male case with a giant undifferentiated pleomorphic sarcoma located above the right scapula.

Silent sinus syndrome after rhinoplasty: a case report.

Silent Sinus Syndrome is a rare syndrome that usually involves the maxillary sinus. In this case report, we present a rare case diagnosed as Silent Sinus Syndrome with frontal, ethmoid and maxillary sinus involvement which was presented with periorbital complaints after the rhinoplasty operation performed in our clinic.
