Bowen's disease is an intraepidermal squarnous cell carcinoma referred to also as squamous cell carcimona in situ. Approximately two-thirds of Bowen's disease consist of solitary lesion while remaining show multiple lesions, We experienced a 68-year old male patient who had multiple erythematous pathes and plaques covered with scales and grayish crusts developing on the trunk and both lower extremities. At first, clinically we suspected psoriasis, seborrheic keratosis, eczema and mycosis fungoides, and finally histopathologic features revealed Bowen's disease showing transformation to invasive squamous cell carcinorna.

Transcranial cerebral oximetry has been successfully used in a variety of neurosurgical conditions, primarily those associated with disturbed cerebral circulation. It has been also used in intraoperative monitoring of aortic dissection and surgical procedures performed under deep hypothermia and circulatory arrest. During disending aortic arch exposure, sudden cerebral oxygen saturation change from 63% to 48% was detected. After therapeutic bypass, cerebral oxygen saturation was increased to 65%. During aortic arch repair, deep hypothermic circulatory arrest with retrograde cerebral perfusion was applied for 130 min and cerebral oxygen saturation slowly decreased from 65% to 52%. Patient was discharged from hospital without neurologic complication and cognitive funtion disturbance.

BACKGROUND: The initiation of treatment seems to be important in provoking preemptive analgesia and to provide excellent postoperative pain control. To verify the effectiveness of postoperative analgesia and preemptive effects, pre-incisional and post-incisional epidural infusion of morphine and bupivacaine mixture were compared. METHODS: Patients scheduled for elective upper abdominal surgery were divided into 2 groups. Each group received 2 mg of morphine in 10 ml of 0.25% bupivacaine as a bolus followed by 0.1 mg/ml/hr of morphine infusion in 0.125% bupivacaine epidurally. In post-incisional group, the epidural injection of mixture was started 15 minutes after skin incision and in pre-incisional group, the epidural infusion of mixture was started 15 minutes before skin incision. Each groups were evaluated in visual analogue scales (VAS) for pain, pain scores in movement, and total administered doses in postoperative 1, 2, 4, 8, 24, 48, and 72 hours and compared with each others. RESULTS: There were no differences between pre-incisional and post-incisional start of continuous epidural mixture infusion of morphine and bupivacaine in VAS for pain, pain scores at movement, and total amount of infused doses for 72 hours postoperatively. Also, there were no differences in the incidence of complications and satisfactions of patients between two groups. CONCLUSIONS: The continuous epidural mixture infusion of morphine 0.1 mg/ml/hr in 0.125% bupivacaine following a bolus dose of 2 mg morphine in 0.25% 10 ml bupivacaine has no difference in postoperative analgesic effect whether it starts after or before surgical incision.

The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

A 4-year-old boy have had widespread, multiple, dark brownish, verrucous ]papular plaques on the neck, left chest, right side of abdomen, back and penile skin since birth. Clinical features and light and electron microscopic findings were consistent with ichthyosis hystrix. The patient was successfully treated with systemic administration of etretinate and vitamin E.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.
