We investigated the overall test-retest reliability and other psychometric properties of a self-report version of the Liebowitz Social Anxiety Scale (LSAS) translated into Hebrew. We also evaluated the utility of three new subscales that were identified by nonparametric analysis (multidimensional scaling; MDS). Two hundred and seven patients who sought treatment for social anxiety or panic disorder were evaluated. All patients completed the self-administered version of the LSAS. A subsample completed the LSAS a second time prior to the beginning of treatment. The results indicate that the self-report format of the LSAS translated into Hebrew demonstrates high test-retest reliability, internal consistency, and discriminant validity. Additionally, some evidence for convergent and divergent validity was noted, and treatment sensitivity was high. MDS analysis followed by the investigation of common underlying facets for items related in two-dimensional space identified three subgroups: 1) the Group Performance/Interaction ("Group") subscale that consists of group performance and group interaction items; 2) the Dyadic Interaction ("Dyadic") subscale that consists of Dyadic interaction items; and 3) the Public Activities ("Public") subscale that consists of individual activities carried out in public. The three new subscales identified by MDS appear to provide clinically relevant information that relates to both demographic and treatment outcome variables and warrant further study.

This study was undertaken to determine if intensive dietary therapy, home blood glucose monitoring, and the selective use of insulin can be effective in preventing fetal macrosomia. All patients were screened at 24 to 28 weeks' gestation using a modification of O'Sullivan's criteria. The 153 patients diagnosed as gestational diabetics by the study protocol were placed on a 1800 to 2000 Kcal American Diabetes Association diet and taught home glucose monitoring. Insulin therapy was initiated only if blood glucose control was inadequate. There were no significant differences (p greater than 0.05) between the study and reference populations in regard to mean birthweight or the incidence of macrosomia. Since our study criteria for diagnosing gestational diabetes were slightly different from those of the National Diabetes Data Group (NDDG), data from 99 patients meeting the NDDG criteria were analyzed in a similar manner. No significant differences were found between this subgroup and the reference population. Since only 7.2% of our study patients required insulin, we conclude that the incidence of fetal macrosomia in gestational diabetes can be kept equal to that of the general population by a program of intensive dietary therapy and home glucose monitoring, with insulin being used only therapeutically, not prophylactically.

Objective. The purpose of this series was to evaluate the prenatal sonographic findings and postnatal outcomes in 2 fetuses with mediastinal lymphangiomas. Methods. The fetal images were compared with postnatal imaging and surgical findings. Results. The 2 fetuses had anechoic mediastinal masses at 25 and 22 weeks, which proved to be lymphangiomas. One, located in the anterior mediastinum, also enveloped the superior vena cava, brachial plexus, phrenic nerve, larynx, and lower parts of the neck vessels and extended into the subcutaneous tissues of the anterior chest wall through an intercostal space. In the second patient, the lymphangioma appeared to be a unilocular cyst, which involved the deep tissues of the neck as well as the posterior and lateral mediastinum. Both required 2 interventions after birth. Conclusions. Fetal mediastinal lymphangiomas appeared anechoic and sent extensions into the neck in the first case, around the superior vena cava, through the intercostal spaces to the skin, and around the brachial plexus in the second case, and deviated the trachea in both cases. In 1 case, there was also ectasia of the superior vena cava. This ability to entwine around vital structures can make it difficult to determine the extent of involvement on antenatal sonography and to remove lymphangiomas completely, and recurrence is common.

The purpose of this series was to evaluate the prenatal sonographic findings and postnatal outcomes in 2 fetuses with mediastinal lymphangiomas. Case DescriptionsCase 1 A 22-year-old patient, gravida 3, para 2, was seen for sonographic examination at 25 weeks' gestation. A cystic mass measuring 3.3 × 0.7 cm with some small septations was located between the heart apex and left chest wall (Figure 1) and extended up around the base of the superior vena cava (SVC). The SVC appeared dilated and irregular, but no obstruction could be identified (Figure 2). No flow was seen within the cystic mass, and although there were multiple septations, there were no solid components. The differential diagnosis included a

Enlarged vascular spaces diffusely distributed throughout the myometrium proved to be a cavernous hemangioma. Cesarean delivery in the present case produced some additional bleeding that was easily controlled, and the uterus was closed without incident.
