Intrauterine restriction (IUGR)

Perinatal mortality and morbidity is markedly increased in intrauterine growth restricted (IUGR) fetuses. Prenatal identification of IUGR is the first step in clinical management. For that purpose a uniform definition and criteria are required. The etiology of IUGR is multifactorial and whenever possible it should be assessed. When the cause is of placental origin, it is possible to identify the affected fetuses. The major complication is chronic fetal hypoxemia. By monitoring the changes of fetal vital functions it is thus possible to improve both management and outcome. The timing of delivery is crucial but the optimal management scheme has not yet been identified. When IUGR is identified at very early gestational ages, serial assessments of the risk of continuing the in utero fetal life under adverse conditions versus the risks of the prematurity should be performed. Delivery of IUGR fetuses should take place in centers where appropriate neonatal assistance can be provided. Careful monitoring of the IUGR fetus during labor is crucial as the IUGR fetus can quickly decompensate once uterine contractions have started.     

Sphincter of Oddi-preserving and T-Tube-free Laparoscopic Management of Extrahepatic Bile Duct Calculi

Background  

The current management of choledocholithiasis remains a controversial topic. Popular options for treatment include preoperative endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) followed by laparoscopic cholecystectomy (LC), or LC and laparoscopic common bile duct exploration (LCBDE) with T-tube decompression. Some concerns suggest that sphincterotomy has significant long-term complications as a result of sphincter of Oddi (SO) dysfunction, and T-tube decompression is historically associated with many complications and discomfort. The purpose of this study was to demonstrate our simple, safe techniques of LCBDE without a T-tube and with an intact SO.     

Personal Autonomy and Authenticity: Adolescents’ Discretionary Use of Methylphenidate

Minors with attention-deficit-hyperactivity disorders (ADHD) are liable to use pharmacological treatment against their will and may find their authentic “I” modified. Thus, their use is widely criticized. In this study, the effect of ADHD drugs on adolescents’ personal experience is examined. The goal is to understand how psychological changes that young people experience when they take these medications interrelate with their attitude toward being medicated. Methylphenidate is the most common pharmacological treatment for ADHD. We look into the change that Israeli adolescents undergo when they use it; their experience in controlling the change, and their assessment of the meaning of the change for their lives. Thirty-eight adolescents participated in semi-structured interviews. The findings, analyzed using grounded theory, show that methylphenidate affects the participants’ demeanor, mood, and even preferences. The participants, aware of these effects, apply discretion in taking methylphenidate and thus influence their traits and their willingness to engage in various activities. When needing to prepare for a matriculation exam, for example, they take methylphenidate; when they need to be creative or sociable, they avoid it and enjoy what they consider the advantages of ADHD, such as creativity and spontaneity. As discretionary users, they shape their life stories in a way that makes them more meaningful and diverse, better tailored to their social surroundings, and more useful in maintaining personal autonomy in the course of pharmacological treatment of ADHD.     

Risk factors for prematurity and premature rupture of membranes: A prospective study of the vaginal flora in pregnancy

Prematurity remains a major cause of perinatal mortality in the United States. Some research has indicated that infectious agents play a role in either initiating preterm labor, causing premature rupture of the membranes, or preventing tocolysis. This study attempted to determine if the presence of various vaginal pathogens in early pregnancy was associated with the subsequent development of premature rupture of membranes or preterm labor. We found that among 233 evaluable patients those with Trichomonas vaninalis were significantly more likely to have premature rupture of the membranes (p < 0.03), and those with Bacteroides sp. were more likely to be delivered of their infants before 37 weeks (p < 0.03) and to have infants weighing less than 2500 gm (p < 0.05). Those with Ureaplasma urealyticum more frequently began preterm labor (p < 0.05). Preterm premature rupture of the membranes was found significantly more often among patients with Bacteroides sp. Stepwise multiple logistic regression analysis indicated that those associations were not related to the number of previous abortions, deliveries, or preterm deliveries or to maternal age. We conclude that microbiologic screening in early pregnancy may aid in the assessment of patient risk for preterm delivery.
