The influence on students' specialty selections of faculty evaluations and mini-board scores during third-year clerkships.

The authors investigated whether graduating students' specialty choices were influenced by favorable faculty evaluations and mini-Board scores during their third-year clerkships, and if so, whether the influences were gender-specific. Data were collected from a total of 53 students in two classes, 1988-89 and 1988-90. Univariate and multivariate tests were performed, and the results were analyzed between each class group and between genders in both groups. These results also were compared with information about the students gathered before they matriculated. In general, the results showed a gender-specific correlation: for each rotation where the women's faculty evaluations were significantly higher than the men's, the women subsequently outnumbered the men in choosing that rotation's specialty. Conversely, for each rotation where the men's mini-Board scores were significantly higher than the women's, the men outnumbered the women in choosing that rotation's specialty. The most notable difference was in pediatrics: 8% of the women had indicated an interest in that specialty on the prematriculation questionnaire, while almost one-third of the women in the classes of 1990 and 1991 chose pediatrics residencies. These findings suggest that the favorable scores and evaluations may be one of the influences for students' specialty choices, and that their influence may be gender-specific.     

Hemorrhagic and nonhemorrhagic brain lesions: evaluation with 0.35-T fast MR imaging

Two fast magnetic resonance (MR) imaging techniques, advanced Fourier and partial-flip imaging, were used at 0.35 T to examine 21 patients with suspected intracranial lesions; the results were quantitatively compared with a conventional spin-echo study. Both of the fast MR techniques yielded a fourfold reduction in imaging time per section. The advanced Fourier sequence showed contrast that was identical to the conventional spin-echo study with signal-to-noise ratios of 58% and 57% for the first and second echoes, respectively. The partial-flip sequence showed a contrast of 109% and 57% for lesions versus substantia alba, and 107% and 78% for substantia grisea versus substantia alba relative to the first and second echoes of the conventional spin-echo study. The partial-flip sequence was particularly sensitive to magnetic susceptibility; this produced artifacts that may undermine the usefulness of partial flip for routine screening in certain parts of the brain. However, this susceptibility significantly improved the detection of intracranial hemorrhage when compared with the spin-echo sequence, particularly when combined with phase mapping of the partial-flip study.     

Compliance with screening mammography. Survey of primary care physicians

A survey of primary care physicians in the greater Tampa Bay metropolitan area was conducted to determine compliance with screening mammography and associated physician characteristics. Information requested included their age, sex, specialty, and board certification status, and the ages and frequencies that they recommend screening mammography for their patients. A total of 565 physicians responded. Even though 88% indicated they follow American Cancer Society recommendations when advising screening mammography, only 62% were actually in full compliance. A significantly greater percentage of obstetricians/gynecologists were compliant (74%) compared to other specialties (family practice, 57%, p = .006; internal medicine, 56%, p = .007; general practice, 53%, p = .003). Women physicians were more likely to be compliant than men (83% versus 58%, p less than .001), and younger physicians more likely than older physicians (72% versus 49%, p less than .001). There was no significant difference in compliance rates between board certified and noncertified physicians.     

Narrative and procedural discourse in temporal lobe epilepsy.

It is well established that some individuals with temporal lobe epilepsy (TLE) demonstrate language deficits at the single word level. However, discourse production rarely has been examined quantitatively within this group. This study compared adult TLE patients with an early seizure onset (< or = age 14 years, n = 27) to a control group (n = 28) on narrative and procedural discourse tasks. As a group, the TLE patients performed normally on the procedural discourse task, but differed significantly from the controls on several narrative discourse variables. At the individual level, 30% of the TLE patients versus 4% of the controls demonstrated impaired discourse ability (p and 0.01). Within this early onset TLE group, discourse performance was not associated with demographic or seizure history variables. Considering the cognitive domain, discourse performance correlated significantly with working memory. In summary, mild discourse dysfunction was present in a significant minority of early onset TLE patients, but this deficit was not closely associated with other language measures. Discourse ability and its neuropsychological, neuroanatomical and conversational speech correlates deserve further study in TLE patients.     

Effect of HLA class I or class II incompatibility in pediatric marrow transplantation from unrelated and related donors

The degree of histoincompatibility that can be tolerated, and the relative importance of matching at individual HLA class I and class II locus in bone marrow transplantation (BMT) has not been established. We hypothesized that matching for HLA-DR may not be more important than matching for HLA-A or HLA-B in selection of a donor for successful BMT. We retrospectively analyzed the outcomes of 248 consecutive pediatric patients who received allogeneic BMT from related donors (RD, n = 119) or unrelated donors (URD, n = 129). HLA-A and HLA-B were serologically matched, and HLA-DRB1 were identical by DNA typing in 69% of donor-recipient pairs. Most patients (89%) had hematologic malignancies; the rest had aplastic anemia or a congenital disorder. One HLA-A antigen mismatch was associated with a decrease in survival (p = 0.003) and a delay in granulocyte engraftment (p = 0.02) in recipients of RD marrow; as well as a decrease in survival (p = 0.02) and the development of severe acute graft-versus-host disease (GVHD) (p = 0.03) in recipients of URD marrow. One HLA-B antigen mismatch was associated with a decrease in the survival (p = 0.05) and the development of severe GVHD (p = 0.0007) in recipients of RD marrow. One HLA-DRB1 allele mismatch was associated only with a decrease in the survival (p = 0.0003) of recipients of RD marrow. Results of this study suggest that disparity in HLA-A and HLA-B antigens may not be better tolerated than disparity in HLA-DR allele in allogeneic BMT. Further studies are warranted to confirm our results.     

Thyroid tumors following thymus irradiation

About 2,650 persons who received X-ray treatment for purported enlarged thymuses in infancy and 4,800 sibling controls have been followed by mail questionnaire for an average of 29 years to observe their incidence of thyroid tumors. The follow-up rate in the latest survey was 88% in both groups. The radiation doses to the thyroid gland ranged from 5 to over 1,000 rad, with 62% receiving less than 50 rad. To date 30 thyroid cancers and 59 benign thyroid adenomas have been detected in the irradiated group, as compared with 1 thyroid cancer and 8 adenomas in the control group. The relative risks in the irradiated group were about 45 for thyroid cancer and 15 for benign thyroid adenomas. The dose-response curve for thyroid cancer was essentially linear, although a linear-quadratic curve could not be ruled out. For thyroid adenomas the risk per rad was somewhat greater at lower doses than at high doses. For both thyroid cancers and adenomas the absolute excess risk per rad was two to three times as great in females as males. Within the limitations imposed by the treatment regimens and the sample size, there was no indication of a "sparing" effect due to dose fractionation for either thyroid cancers or adenomas. There was an excess risk for both malignant and benign thyroid tumors for at least 40 years post irradiation. For thyroid cancer the radiogenic risk appeared to be additive with respect to time, rather than the age-specific natural rates of cancer being multiplied.     

Pancreatic pseudocysts drained through a percutaneous transgastric approach

We describe a new method for the percutaneous drainage of pancreatic pseudocysts using a transgastric approach. We used this technique in three dogs and six patients for whom no other "safe" access route was available. The procedures were performed under US guidance alone or with US combined with fluoroscopy. No complications were observed.
