Shyness and face scanning in children

Contrary to popular beliefs, a recent empirical study using eye tracking has shown that a non-clinical sample of socially anxious adults did not avoid the eyes during face scanning. Using eye-tracking measures, we sought to extend these findings by examining the relation between stable shyness and face scanning patterns in a non-clinical sample of 11-year-old children. We found that shyness was associated with longer dwell time to the eye region than the mouth, suggesting that some shy children were not avoiding the eyes. Shyness was also correlated with fewer first fixations to the nose, which is thought to reflect the typical global strategy of face processing. Present results replicate and extend recent work on social anxiety and face scanning in adults to shyness in children. These preliminary findings also provide support for the notion that some shy children may be hypersensitive to detecting social cues and intentions in others conveyed by the eyes. Theoretical and practical implications for understanding the social cognitive correlates and treatment of shyness are discussed.     

Allogeneic bone marrow transplantation in chronic lymphocytic leukemia: 17 cases. Report from the EBMTG

Allogeneic bone marrow transplantation (BMT) was performed in 17 patients with chronic lymphocytic leukemia (CLL): 15 resistant and two untreated forms. There were 12 males and five females with a mean age of 40 years (32-49). The conditioning regimens and graft-versus-host disease (GVHD) prophylaxis varied. Successful engraftment was obtained in 15 evaluable cases. Lymphocytosis and clinical symptoms subsided in all but one case. All 15 evaluable patients developed acute GVHD. Among the 17 patients grafted, one early death was observed at the 15th day post-BMT, and one refractory patient died 2 months after BMT. Of the remaining 15 patients in complete remission (CR), four died from GVHD, hemorrhage and graft failure, and two relapsed at 7 and 54 months after BMT and died. Nine patients are alive in CR with a mean follow-up of 25.6 months (4-48). Chimerism was complete in eight patients and partial in the two T cell-depleted cases. In one case, an immunoglobulin gene rearrangement study showed no residual disease. These results suggest that allogenic BMT might be an alternative and possible curative therapy for refractory CLL in young patients when performed relatively early in the disease.     

Frequency of central lesions in polyneuropathy associated with IgM monoclonal gammopathy: an MRI, neurophysiological and immunochemical study.

CNS lesions were studied in polyneuropathy associated with IgM monoclonal gammopathy. Eleven out of 12 patients with IgM MGUS and one patient with Waldenstrom's disease had clinical and electrophysiological features indicating a demyelinating polyneuropathy. MRI showed CNS white matter lesions in two cases. Antibodies reacting against glycolipids present in CNS white matter were present in five cases, two of which had abnormal MRI. Central conduction times cortex-C7, obtained by magnetic stimulation, were prolonged in 3/8 patients, of which two patients had anti-CNS glycolipid antibodies.     

Could bipolar vessel sealers prevent bile leaks after hepatectomy?

BACKGROUND AND AIMS: The aim of this work was to test the feasibility of using a bipolar low thermal acting system inducing collagenic sealing but not protein coagulation to secure hepatic parenchyma cutting. MATERIALS AND METHODS: Thirty consecutive hepatectomies were carried out using kellyclasy plus ligatures and clips (controls), while the following 50 hepatectomies used kellyclasy plus bipolar vessels sealer (BVS). Blood loss, duration of hepatic pedicle clamping, length of hospital stay, and complications were recorded. RESULTS: There was no statistically significant difference in blood loss and duration of clamping between controls and BVS. Specific complications (9/21 in the control group vs 1/49 for the BVS group, p<0.00045) and length of hospital stay (14 days in the control group vs 11 days in the BVS group, p<0.014) were statistically lower in BVS group than in the controls, mainly due to prevention of bile duct leakages. CONCLUSIONS: Our data suggest that BVS may be particularly efficient to achieve bilistasis leading to the highest level of safety in performing hepatectomies. Further studies are now needed to confirm its superiority on the classical biliary ducts occlusion techniques.
