A Japanese businessman on his first visit to the United States was pleased to be invited to a U.S. executives home for cocktails. He arrived promptly at 7 p.m. The host introduced him to a small group of people, and then returned to the front door to greet others who were arriving. The Japanese businessman seemed to have nothing to contribute on the seemingly mindless topics that were discussed. After a few minutes, the others in the group wandered off.

a ground-glass appearance and air bronchogram on the chest X-ray. Finally, because the baby Pao2 was less than 45 torr shortly after birth, the ductus arteriosus remained patent, producing the syndrome known as persistent pulmonary hypertension of the neonate (PPHN). As the infant's condition improved and his PaO2 increased, the ductus arteriosus closed and the signs and symptoms associated with PPHN disappeared. At the time of this writing, the baby was a perfectly normal 3 year-old boy who was attending half-day preschool sessions 5 days per week. 1. In this case, what are the major anatomic alterations of the lung associated with the respiratory disease that developed in the infant? 2. Describe the pathophysiology that develops as the conditions listed in question 1 worsen. 3. Describe how the following conditions are manifested in the clinical setting: Decreased pulmonary diffusion: Decreased lung compliance: 4. Why did PPHN develop in the infant in this case? How did this condition improve? Discussion This case illustrater the possible adverse effects of a premature birth on the infant's alveolar-apillary gas exchange units and pulmonary circulation. During fetal development, the alveolar-capillary system and the quantity of pulmonary surfactant usually are not sufficient to support life until the 28th week of gestation or beyond. In this case, the baby was born at the very beginning of this time period. Thus, because of the immaturity of the baby's alveolar- capilary system, the ability of the type II cells to produce pulmonary surfactant was inadequate. As a result of the insufficient amount of pulmonary surfactant, the pathologic processes of a common newborn respiratory disorder called respiratory distress syndrome (RDS) developed. The anatomic alterations of the lungs associated with RDS indude interstitial and intra-alveolar edema and hemorrhage, alveolar consoldation, intra-alveolar hyaline membrane formation, and atelectasis. All of these pathologic processes cause the alveolar-capillary membranes thickness to increase. As this condtion progressively worsened, the diffusion of oxygen between the alveoli and the pulmonary capillary blood decreased, and the infant's lung compliance decreased. Clinically, the decreased diffusion of oxygen was manifested by cyanosis, increased respiration rate and heart rate, and decreased Pa. The decreased lung compliance was manifested by nasal flaring, intercostal retractions, exhalation grunting, bilateral crackles, and.

A Duke le pareca que Lucinda Furtado, una asistente de limpieza, de alguna manera era un vnculo con las preocupaciones sobre la moral del personal. Lucinda, una inmigrante de Filipinas, haba estado trabajando en el hotel durante diez aos, pero se estaba convirtiendo en un problema para sus supervisores y compaeros de trabajo. Lucinda actu de maneras que parecan socavar a sus supervisores y compaeros de trabajo: se haban usado los trminos abusivo y acoso sobre ella. Desarroll la reputacin de ser una "entrometida" al rastrear el trabajo de otros empleados hasta el punto de dejar su propia estacin de trabajo para preguntar a otros empleados sobre sus cargas de trabajo en comparacin con su propia carga de trabajo. Tambin se hizo conocida por otros comportamientos no productivos, como hacer comentarios mezquinos hacia los empleados que "trabajan ms". Ella enviaba mensajes sutiles pero claros sobre el resto del personal, por ejemplo, cambiando obviamente su idioma en medio de las conversaciones cuando ciertas amas de llaves ingresaban a la sala de profesores. Habra quedado bastante claro para el resto del personal que Lucinda haba estado hablando de ellos. Gran parte de sus acciones negativas fueron individuales, a menudo difundiendo rumores sobre otros miembros del personal o sobre el hotel mismo. Durante el perodo en que Duke ocup el cargo de gerente general, l y el gerente de recursos humanos del hotel se haban reunido con Lucinda seis veces para conversaciones documentadas sobre el desempeo. Cuando se discuti su comportamiento, su reaccin tpica fue reclamar "mi error, no lo que quise decir, perdn por causar este problema". Furtado tambin dio a entender que las diferencias culturales fueron la razn del malentendido; las discusiones sobre el desempeo siguieron el mismo patrn. Lucinda aleg un malentendido, jur que su intencin era buena y mencion otras cuestiones no relacionadas. Lucinda a menudo estaba en el centro de las disputas de horarios de trabajo, lo que inevitablemente condujo a sus reclamos de racismo hacia ella por parte de la gerencia y el consiguiente trato injusto. Lucinda revisaba regularmente las asignaciones de habitaciones en los portapapeles de otros empleados que estaban almacenados en sus carritos de servicio. Los portapapeles indicaban el nmero de estancias y salidas y Lucinda quera verificar para asegurarse de que no se le asign un "nmero injusto de salidas". Lucinda se asegur de que la programacin del trabajo siempre causara drama y dejara a su supervisora, la ama de llaves ejecutiva, siempre preguntndose qu iba a pasar a continuacin. Una queja tpica era que no la trataban de manera justa cuando haba solicitado das libres. En un caso, dos amas de llaves haban pedido das libres el mismo da. Me haban explicado que eran flexibles con las fechas. Su supervisora, la ama de llaves ejecutiva, permiti que ocurriera esta situacin porque la ocupacin del hotel en ese da en particular era baja y su ausencia no tendra un impacto negativo.

A El proceso de produccin de peridicos ha recorrido un largo camino desde los viejos tiempos cuando el peridico se escriba, editaba, compona y finalmente se imprima en un edificio con los periodistas trabajando en los pisos superiores y las imprentas en la planta baja. En estos das, es probable que el editor, los subeditores y los periodistas que elaboran el peridico se encuentren en un edificio totalmente diferente o incluso en una ciudad diferente. Esta es la situacin que ahora prevalece en Sydney. El diario se compila en la sede editorial, conocida como el centro de preimpresin, en el corazn de la ciudad, pero se imprime lejos en los suburbios en el centro de impresin. Aqu los seres humanos son una minora ya que gran parte del trabajo lo realizan mquinas automatizadas controladas por computadoras. B Una vez que se ha creado el peridico terminado para la edicin de la maana siguiente, todas las pginas se transmiten electrnicamente desde el centro de preimpresin al centro de impresin. El sistema de transmisin es una actualizacin del sofisticado sistema de facsmil de pginas que ya se utiliza en muchos otros peridicos. Un colocador de imgenes en el centro de impresin entrega las pginas como pelcula. Se tarda menos de un minuto en producir cada pgina, aunque para las pginas en color se envan cuatro versiones, una vez para cada una, para negro, cian, magenta y amarillo. Luego, las pginas se procesan en negativos fotogrficos y la pelcula se usa para producir planchas de impresin de aluminio listas para las prensas. C Una procesin de vehculos automatizados est ocupada en el nuevo centro de impresin donde se imprime el Sydney Morning Herald todos los das. Con luces intermitentes y bocinas de advertencia sonando, los robots (para darles su nombre correcto, los LGV o vehculos guiados por lser) lucen para todo el mundo como mquinas entusiastas de una pelcula de ciencia ficcin, mientras siguen sus propios caminos aleatorios alrededor de la planta. continuar con sus trabajos. La automatizacin de este tipo ahora es estndar en todas las plantas de peridicos modernas. Los robots pueden detectar personal no autorizado y alertar al personal de seguridad inmediatamente si encuentran un "intruso"; No es sorprendente que ya se cuenten cuentos fantsticos sobre las mquinas que comienzan a adquirir personalidades propias. D El trabajo principal de los robots, sin embargo, es cambiar el papel de peridico (el papel de impresin) que llega a la planta en bobinas enormes y emerge en el otro extremo algn tiempo despus como peridicos. Una vez que se determina el tamao del peridico del da y el orden de publicacin en la oficina central, la informacin se ingresa a la computadora y los LGV se programan para realizar su trabajo. Los LGV recogen las bobinas de papel del tamao adecuado y las llevan a donde tienen que ir. Cuando la prensa necesita otra bobina, su computadora alerta al sistema LGV. Los Sydney LGV se mueven afanosamente por la sala de prensa cumpliendo sus dos func.
