BACKGROUND During the 1990's hospitals in the U.S were faced with cost containment charges, which may have disproportionately impacted hospitals that serve poor patients. The purposes of this paper are to study the impact of safety net activities on total profit margins and operating expenditures, and to trace these relationships over the 1990s for all U.S urban hospitals, controlling for hospi...

PURPOSE To report a successful eyelid reconstruction performed using the residual tarsus after excision of a sebaceous gland carcinoma. CASE REPORT An 86-year-old woman presented with a sebaceous gland carcinoma of the upper eyelid margin. After excision of the tumor, she underwent reconstructive surgery of the superior eyelid performed using the residual tarsus. Because the tumor was localiz...

Sometimes we see patients with disappearing vermilion totally or in some parts. It seems that the marginal skin has advanced to the lip surface with the same color. It occurs mainly in lower lip. The majority of patients had history of recurrent herpes labialis on their lips, in the same location as disappearing vermilion. Disappearing vermilion is not accompanied by any change in consistency o...

High-resolution sedimentological and micropaleontological studies of several deep-sea cores retrieved from the levees of the Celtic and Armorican turbidite systems (Bay of Biscay — North Atlantic Ocean) allow the detection of the major oscillations of the British–Irish Ice Sheet (BIIS) and ‘Fleuve Manche’ palaeoriver discharges over the last 30,000 years, which were mainly triggered by climate ...

In this paper, a new method is proposed for the speed control of a three-phase current forced synchronous machine drive. This metohd is based on the use of an approximate constant commutation safety margin angle in the output thyristor bridge of the drive system as well as on the compenastion of stator magnetization reaction. The commutation process in the output converter of the machine driv...

OBJECTIVE The purpose of this study is to elicit the amount of safety margin necessary around the ameloblastic lesion in view of preventing further recurrence. MATERIALS AND METHODS The study consisted of 25 cases of mandibular ameloblastoma. Diagnosis was based on clinical and radiological analysis and confirmed by histopathological report. An incisional biopsy was done preoperatively to con...

431 ImageS nosis from basal cell carcinoma originating from the sebaceous gland. In the erythematous mass containing the nevus sebaceous, a wide excision was performed with a safety margin of 5 mm. A frozen section biopsy showed that there were no tumor cells on the resection margin. Following the resection, scalp defects of 2.5×5.0 cm in size remained (Fig. 2). The defects were reconstructed u...
