Chest drain placement is a standard procedure for treating pneumothorax and pleural effusions and has a low complication rate. It is a safe and efficient procedure if image guidance is used. If the anatomic orientation is hampered and neither air nor fluids can be initially aspirated, more complex imaging than a chest x-ray is indicated to avoid major complications. We report the case of an 88-...

The soil around a drain well is traditionally divided into smeared zone and undisturbed zone with constant hydraulic conductivity. In reality, hydraulic conductivity of the soil changes continuously and it may not be always appropriate to approximate its distribution with two zones. In this study, the horizontal hydraulic conductivity of the soil is described by an arbitrary function of radial ...

Country-level longitudinal data at three-year intervals over 1990–2004 are used to analyze the factors affecting emigration of physicians from Sub-Saharan countries and the effects of this medical brain drain on life expectancy and number of deaths due to AIDS. Data are compiled on emigrating African physicians from 16 receiving Organisation for Economic Co-operation and Development (OECD) coun...

A 55-year-old female was diagnosed to have malignant mucinous cystic neoplasm (MCN) of the distal pancreas. Intraoperatively, the lesion was 10×10×15 cm in size arising from the distal pancreas involving the splenic hilum and transverse mesocolon with no evidence of dissemination. So she underwent en bloc resection of the tumor with distal pancreatectomy, splenectomy and segmental resection of ...

The effects of surface states on the gate offset regions of GaAs power MESFETs are analyzed using a two-dimensional device simulator with a Shockley-Read-Hall statistics model for the surface states. Assuming electron trap type surface states (ET) and hole trap type surface states (HT) +, it is found that the trap properties cause a large difference in DC performance and pulse operation of the ...

We describe a simple technique of drain fixation in head and neck surgery using a beaded 2/0 nylon suture and a 'clove hitch' to achieve a non-slip fixation to the drain.

We experienced two cases of lung injury resulting from fluted silastic drain extraction under reservoir-generated negative pressure suction. In the first case, a 67-year-old man underwent coronary artery bypass grafting. A 19 Fr BLAKE drain was placed at the pericardial cavity, the mediastinum, and the left thoracic cavity. All three drains were connected to J-VAC reservoirs. After removing the...

The objective of this paper is to simulate static I-V and dynamic characteristics of an appropriated and recessed nGaN/AlxGa1-xN/GaN high electron mobility (HEMT). Using SILVACO TCAD device simulation, and optimized technological parameters; we calculate the drain-source current (IDS) as a function of the drain-source voltage (VDS) for different values of the gatesource voltage (VGS), and the d...

OBJECTIVE Prior studies suggested that early drain removal prevented the development of pancreatic fistula (PF) after pancreaticoduodenectomy (PD), but there has been no corresponding prospective trial for distal pancreatectomy (DP). The purpose of this study was to determine the safety and efficacy of early drain removal and triple-drug therapy (TDT) with gabexate mesilate, octreotide and carb...
