ABSTRACT
Ultrasound-guidance is frequently used at the time of biopsy. Its numerous advantages include: lack of ionizing radiation, real-time visualization of the needle tip, flexibility to approach lesions from variable and complex angles, wide availability of ultrasound units. A certain level of experience is nonetheless required to ensure adequate and successful lesion targeting. New software are available to assist the operators. "Electromagnetic navigation" can assist in locating the needle tip and predicting its trajectory. Image fusion with previous cross-sectional imaging studies can assist in detecting lesions that are less conspicuous on routine ultrasound images.

Inhalation injury greatly increases the incidence of respiratory failure and the acute respiratory distress syndrome. It is also the cause of most early deaths in burn victims. The aim of our research was to study the incidence, early diagnosis, complications, and management of inhalation injury and to discuss the relation between inhalation injury and death in burn patients.This study included 130 burn patients with inhalation injury admitted to Menoufiya University Hospital Burn Center, Egypt, from January 2004 to April 2008 (61 males and 69 females). We found that the presence of inhalation injury, increasing burn size, and advancing age were all associated with increased mortality (p < 0.01). The incidence of inhalation injury in our study was 46.3% (130 patients were identified as having inhalation injury out of 281). The overall mortality for patients with inhalation injury was 41.5% (54 patients out of 130) compared with 7.2% (11 patients out of 151) for patients without inhalation injury. These statistical data make it clear that inhalation injury is an important factor for the prediction of mortality in burn patients. Approximately 80% of fire-related deaths are due not to the burn injury to the airway but to the inhalation of toxic products, especially carbon monoxide and hydrogen cyanide gases. Inhalation injury is generally caused by thermal burns, mostly confined to the upper airways.Major airway, pulmonary, and systemic complications may occur in cases of inhalation injury and thus increase the incidence of burn patient mortality.
ABSTRACT
Female pupal weight and fecundity of mother moth of Antheraea assama Westwood fed with four different food plants have been studied. Litsaea polyantha fed females showed significantly higher pupal weight and higher rate of oviposition in comparison to three food plants Machilus bombycina, Litsaea salicifolia and Cinnamomum glaucescens. The number of eggs laid was correlated with the pupal weight. The correlation co-efficient (r = 0.9730) showed positive and significant correlation at 1% level. The pupal weight was found to be the best and genuine estimator of fecundity.
