Reduction of operating and recovery room times and overnight hospital stays with interscalene blocks as sole anesthetic technique for rotator cuff surgery
The effort to decrease hospital stays and to increase operating room efficacy has become an important consideration in the practice of anesthesia.
Fifty-three patients who underwent shoulder rotator cuff repair in the sitting position were divided into four groups according to the anesthesia technique used: Group 1 (general anesthesia), Group 2 (interscalene block), Group 3 (interscalene combined with general anesthesia) and Group 4 (general anesthesia combined with local injection of local anesthetics). Interscalene blocks were performed preoperatively, using a nerve stimulator. After appropriately locating the brachial plexus, a mixture of 40 ml of 2% lidocaine and 0.5% bupivacaine (v/v) was injected.
As compared to general anesthesia, the use of an interscalene block alone reduced the following operating room times: 1) from the patient's arrival in the operating room to the beginning of surgery and 2) from the end of surgery to the patient's departure from the operating room. Use of the interscalene block also resulted in a reduction of recovery time when compared to Groups 1, 3 and 4 by 40, 56 and 66%, respectively. Compared to Group 1, this anesthesia technique was furthermore associated with a 64% decrease in the number of patients hospitalized overnight.
This study confirms that the interscalene block as sole anesthesia technique is safe and effective and can contribute to shorten the hospital length of stay of patients undergoing shoulder rotator cuff surgery
Prenatal imaging features suggestive of liver gestational allo immune disease
International audienceWe report prenatal imaging features of four cases of neonatal hemochromatosis due to an alloimmune disease. All cases exhibited intra uterine growth restriction (IUGR) without arguments for a vascular etiology, associated with oligohydramnios. Placental hydrops was present in 75% of cases. Splenomegaly was identified in one case. Other causes of NH have been ruled out during diagnostic workup including karyotype, detection of IGFBP-1 to evaluate a premature rupture of membranes, maternal serologic tests. MRI was performed in two cases and showed an atrophic liver associated with a low signal intensity on T2-sequence in one case. Prenatal NH was suspected in this later case and the fetus was successfully treated with two IVIG (intravenous immunoglobulins) perfusions performed during pregnancy followed by exchange transfusion and IVIG after birth. The child is doing well with normal liver function tests after 17 months of follow up. Our aim was to highlight the importance of suggesting NH-GALD when facing IUGR with oligohydramnios, ascites, placental hydrops, splenomegaly on prenatal ultrasound with negative work up for placental vascular pathologies and infectious fetopathies. MRI might be of a good help, showing an atrophic liver but enhancing iron overload in hepatic and extrahepatic tissue is helpful but not constant

An early, abundant cytotoxic T-lymphocyte response against Theiler's virus is critical for preventing viral persistence
Clonal evolution of CD8+ T-cell expansions in HIV-infected patients on long-term HAART
HIV-1 continually replicates in spite of long-term highly active anti-retroviral therapy (HAART) and therefore, it is conceivable that the low level, persistent viral activity could continue to stimulate the hosts immune system despite remaining below the detection limit of the current assays. In this study, we performed a longitudinal analysis of the CD8+ T-cell receptor Vβ repertoire in HAART-treated and untreated HIV patients. HAART-mediated control of viremia, for up to 18 months, did not prevent similar perturbations within the CD8+ Vβ repertoire in both study groups as defined by CDR3 spectratyping. Oligoclonal Vβ expansions, with new dominant CDR3 lengths, were observed throughout the study period. Our findings are compatible with antigen-driven CD8+ immune responses to bursts of replication from a continuously changing viral reservoir, regardless of HAART-mediated suppression of HIV-1 viremia
