RÉSUMÉ
BACKGROUND: The prevalence of sesame food allergy (SFA) has increased over recent years, with the potential of anaphylactic reactions upon exposure. Oral food challenge (OFC) remains the diagnostic standard, yet its implementation may be risky. Commercial skin prick tests (SPT) have a low sensitivity. Investigation of alternate diagnostic methods is warranted. OBJECTIVE: To evaluate the utility of SPT and the basophil activation test (BAT) for SFA diagnosis. METHODS: Eighty-two patients with suspected SFA completed an open OFC to sesame or reported a recent confirmed reaction. Patients were administered skin prick tests (SPT) with commercial sesame seed extract (CSSE) and a high protein concentration sesame extract (HPSE) (100 mg/mL protein). Whole blood from 80 patients was stimulated with sesame seed extract (40-10 000 ng/mL protein) for BAT), assessing CD63 and CD203c as activation markers. RESULTS: Sixty patients (73%) had IgE-mediated reactions to sesame, and 22 (27%) did not react. Receiver operating characteristic (ROC) curve analysis demonstrated an area under the curve (AUC) of 0.87 for HPSE-SPT and 0.66 for CSSE-SPT. At 1000 ng/mL of sesame protein, induction of CD63 and CD203c was weakly but significantly associated with OFC eliciting dose by rank (Spearman's rho = -.42 (P < .01) and -.35 (P < .05) for CD63 and CD203c, respectively). By ROC analysis, the AUC was 0.86 for CD63 and was 0.81 for CD203c sesame-induced basophil expression. Using HPSE-SPT as a first test to definitively diagnose (n = 24) or rule-out (n = 5) SFA and BAT as a second test to diagnose the remainder results in the correct classification of 73 of 80 (91%) patients, leaving one false negative and 4 false positive patients. Two BAT non-responders remain unclassified by this algorithm. CONCLUSIONS & CLINICAL RELEVANCE: While prospective cohort validation is necessary, joint utilization of BAT and SPT with HPSE extract may obviate the need for OFC in most SFA patients.

The sensory systems in animals constantly monitor the environment and process salient and relevant features while subtracting background activity. This process requires continuous recalibration of neuronal gain based on recent history. Adaptation has been postulated to be the key mechanism by which neurons rapidly tune their response curves to represent the entire dynamic range of external inputs. Rodents heavily rely on their vibrissa system while gathering information about their surroundings using whisking. Neuronal adaptation is observed in all stages of sensory processing, from the whisker follicle through the brainstem and thalamus up to the barrel cortex. In this review, we discuss the intrinsic, synaptic and network mechanisms of adaptation such as short-term synaptic depression, inhibitory suppression, balance between excitation and inhibition as well as the role of cascading adaptation. Furthermore, we describe recent findings about the different intensity dependent adaptation properties in the two major somatosensory pathways and their possible implications about coding.

Studies examining the long-term effect of oral immunotherapy in food-allergic patients are limited. We investigated cow's milk-allergic patients, >6 months after the completion of oral immunotherapy (n = 197). Questionnaires, skin prick tests, and basophil activation assays were performed. Of the 195 patients contacted, 180 (92.3%) were consuming milk protein regularly. Half experienced adverse reactions, mostly mild. Thirteen patients (6.7%) required injectable epinephrine. Higher reaction rate after immunotherapy was associated with more anaphylactic episodes before treatment and a lower starting dose (OR = 2.1, P = 0.035 and OR = 2.3, P = 0.035, respectively). Reaction rate in patients who were 6-15 months, 15-30 months, or >30 months post-treatment decreased from 0.28/month to 0.21/month to 0.15/month, respectively (P < 0.01). Milk-induced %CD63 and %CD203c expression was significantly lower in patients >24 months vs in patients <24 months post-treatment (P = 0.038 and P = 0.047, respectively). In conclusion, many patients experience mild adverse reactions after completing oral immunotherapy and some require injectable epinephrine. Progressive desensitization, both clinically and in basophil reactivity, occurs over time.

Ischemia/reperfusion (I/R) injury is the main cause of primary graft dysfunction of liver allografts. Cobalt-protoporphyrin (CoPP)-dependent induction of heme oxygenase (HO)-1 has been shown to protect the liver from I/R injury. This study analyzes the apoptotic mechanisms of HO-1-mediated cytoprotection in mouse liver exposed to I/R injury. HO-1 induction was achieved by the administration of CoPP (1.5 mg/kg body weight i.p.). Mice were studied in in vivo model of hepatic segmental (70 %) ischemia for 60 min and reperfusion injury. Mice were randomly allocated to four main experimental groups (n = 10 each): (1) A control group undergoing sham operation. (2) Similar to group 1 but with the administration of CoPP 72 h before the operation. (3) Mice undergoing in vivo hepatic I/R. (4) Similar to group 3 but with the administration of CoPP 72 h before ischemia induction. When compared with the I/R mice group, in the I/R+CoPP mice group, the increased hepatic expression of HO-1 was associated with a significant reduction in liver enzyme levels, fewer apoptotic hepatocytes cells were identified by morphological criteria and by immunohistochemistry for caspase-3, there was a decreased mean number of proliferating cells (positively stained for Ki67), and a reduced hepatic expression of: C/EBP homologous protein (an index of endoplasmic reticulum stress), the NF-κB's regulated genes (CIAP2, MCP-1 and IL-6), and increased hepatic expression of IκBa (the inhibitory protein of NF-κB). HO-1 over-expression plays a pivotal role in reducing the hepatic apoptotic IR injury. HO-1 may serve as a potential target for therapeutic intervention in hepatic I/R injury during liver transplantation.

By exposing cells of the U118MG glioblastoma cell line to protoporphyrin IX (PPIX) in culture, we found that the 18 kDa mitochondrial translocator protein (TSPO) prevents intracellular accumulation of PPIX. In particular, TSPO knockdown by stable transfection of TSPO silencing siRNA vectors into U118MG cells leads to mitochondrial PPIX accumulation. In combination with light exposure, the PPIX accumulation led to cell death of the TSPO knockdown cells. In the sham control cells (stable transfection of scrambled siRNA vectors), TSPO expression remained high and no PPIX accumulation was observed. The prevention of PPIX accumulation by TSPO was not due to conversion of PPIX to heme in the sham control cells. Similar to TSPO knockdown, the reactive oxygen species (ROS) scavenger glutathione (GSH) also enhanced PPIX accumulation. This suggests that that ROS generation as modulated by TSPO activation may present a mechanism to prevent accumulation of PPIX.

In the United States, 1.4 million people suffer from traumatic brain injury (TBI) each year because of traffic, sports, or war-related injuries. The majority of TBI victims suffer mild to minimal TBI (mTBI), but most are released undiagnosed. Detailed pathologies are poorly understood. We characterized the microscopic changes of neurons of closed-head mTBI mice after increased unilateral trauma using hematoxylin and eosin (H&E) stain, and correlated it with the expression of the apoptotic proteins c-jun, p53, and BCL-2. Minimal damage to the brain increases the number of pyknotic appearing neurons and activates the apoptotic proteins in both hemispheres. Although minimal, increased impact was positively correlated with the increased number of damaged neurons. These results may explain the wide variety of behavioral and cognitive deficits closed-head mTBI causes in mice. Our cumulative results point to the pathological origin of post-concussion syndrome and may aid in the development of future neuroprotective strategies for the disease.

The Truview blade facilitates a view of the vocal cords by indirect laryngoscopy. We prospectively compared the view obtained at laryngoscopy and intubating conditions of Truview (Group 1) or Macintosh (Group 2) blades in 170 patients who were scheduled to undergo general anaesthesia. We studied pre-operative airway evaluation, laryngoscopic view, duration of intubation, maximal force applied during intubation, anaesthetist's estimation of intubation effort on a 1-3 scale, bleeding, teeth and soft tissue damage, and postoperative stridor and hoarseness. The results demonstrated that, whilst the Truview produced a better laryngoscopic view and less maximal force applied during intubation, the duration of intubation was longer. No significant difference was found in the anaesthetist's estimation of intubation effort, tooth damage or postoperative stridor and hoarseness. Significantly fewer patients suffered bleeding and soft tissue damage following intubation with the Truview than with the Macintosh blade. The Truview blade is a useful option for tracheal intubation in patients with normal and anticipated difficult airways.

The aim of the current paper was to determine the chorion's contribution to complement synthesis in the placenta and its regulation by cytokines. Biosynthetic labeling followed by immunoprecipitation with polyclonal antibodies was performed in chorionic tissue and chorion-derived cells. Eight complement proteins, factor B, C3, C1r, C1s, C1 inhibitor, factor H, C4 and C2 were detected in chorionic tissue and were secreted extracellularly. In chorion-derived cells, IL-1beta stimulated factor B synthesis but had no effect on C1r, C1 inhibitor, C1s, factor H and C4. TNFalpha had no stimulative effect on any of the complement proteins tested. In contrast, both IL-1beta and TNFalpha highly induced IL-6 secretion in chorion-derived cells, demonstrating the overall responsiveness of these cells to these stimuli. Interestingly, IFN-gamma increased the synthesis of C1s, C1r, C1 inhibitor, C4 and factor H in chorion-derived cells. The fact that the latter two complement proteins have opposing effects on immune activation of the complement cascade demonstrates the complex balance required to both maintain an ability to ward off infections but simultaneously suppress the immune response to enable tolerance of the allograft fetus.

BACKGROUND: It has been suggested that performing a nerve block under general anesthesia, as customary in pediatric population, may predispose to nerve injury. However, few clinical data exist to either support or refute this assertion. METHODS: We retrospectively reviewed data on all patients who received an axillary block for upper extremity surgery in our institution during an eight-year period. The blocks were performed under sedation or general anesthesia, without using a nerve stimulator. Perioperative records from the Hand Surgery Unit Clinic were reviewed for postoperative complaints and complications. RESULTS: In the eight-year period of the review, 336 patients had axillary block. In total, 230 received the block with sedation and 106 during general anesthesia. All the sedated patients were older than 14 years (mean age 45.2), while of the general anesthesia patients 48 were older than 14 years (mean age 13.9 years). There were six cases of postoperative nerve injury in sedated patients (2.6%) vs. eight cases (7.5%) in the general anesthesia patients. Most patients recovered fully within several weeks. One patient had permanent nerve injury. CONCLUSIONS: Definitive conclusions cannot be drawn because of disparities in patient group demographics (majority of pediatric patients were in the general anesthesia group) and the retrospective nature of this study. Nevertheless, the findings suggest that the conduct of axillary block under general anesthesia in pediatric patients holds a greater potential for nerve injury than when the block is performed under sedation in adults.

We present a technique of retrosternal block for symptomatic treatment for dyspnoea of various aetiologies. In our experience with 20 patients, a retrosternal block using lignocaine improved symptoms within minutes. The block was easy to perform and was helpful when the patients' symptoms were not relieved by conventional therapy. Prospective controlled studies are needed to further assess this simple and promising treatment.

Central neural damage caused by L-cysteine (L-Cys) was first reported more than 30 years ago. Nevertheless, the exact mechanisms of L-Cys-mediated neurotoxicity are still unclear. Preliminary study in mice demonstrated that, following L-Cys injection, animals developed tachypnea, tremor, convulsions, and death in conjunction with documented hypoglycemia. The aim of the present study was to further investigate the mechanism of L-Cys-mediated hypoglycemic effect and neural damage. Neonatal ICR mice (n=6) were injected with L-Cys (0.5-1.5 mg/g body weight [BW]), and their blood glucose and insulin levels were determined up to 90 min following the injection. Experiments were repeated in chemically (streptozotocin [STZ]) pancreatectomized animals. Brain histology was assessed. Mice injected with L-Cys exhibited dose-dependent neurotoxicity and higher mortality as compared with controls. L-Cys (1.2-1.5 mg/g BW) caused severe hypoglycemia (glucose<42 mg/dl) ( P<0.001). In STZ-treated (diabetic) animals, L-Cys (1.5 mg/g BW) increased plasma insulin levels 2.3-fold and decreased serum glucose levels by 50% ( P<0.01). Brain histology revealed destruction of as much as 51% of hippocampal neurons in the L-Cys-treated mice but not in the glucose-resuscitated animals. These findings suggest that L-Cys injection can cause pronounced hypoglycemia and central neural damage which is glucose reversible. Since L-Cys is chemically different from the other excitatory amino acids (glutamate and aspartate), L-Cys-mediated neurotoxicity may be connected to its hypoglycemic effect.

PURPOSE: To determine the prognosis of women with slow rising beta-hCG levels when viability is detected by ultrasound. METHODS: Serum beta-hCG levels were obtained every two to three days in the early first trimester. Doubling-time (DT) of beta-hCG levels was defined as DT exceeding 3.2 days. Sonography was performed at eight weeks and then after 12 weeks. RESULTS: There were 158 consecutive pregnancies evaluated and 111 (70%) had normal rising beta-hCG levels, viable ultrasound at eight weeks, and viable pregnancies after 12 weeks. There were 22 pregnancies with slow rising beta-hCG levels (13.9%) with 16 (72.7%) showing viability at eight weeks but not after the first trimester. A sac-crown rump length discrepancy with a sac smaller than normal was found in 11 of these 16 (68.7%) women. CONCLUSIONS: Patients with slow rising beta-hCG levels should not be given an optimistic prognosis even if viability is demonstrated at eight weeks.

For many years, the expression "cutoff effect of anesthesia," has been used to denote the failure of the higher alcohols or paraffins to produce anesthesia. As such, it is used to assess the plausibility of specific models, proposed for anesthesia. However, the uses were shown, in many respects, to be problematic. This article augments the notion of the cutoff to fit for all cases in which only some of the molecules in a homologous series are anesthetics. We find that the location of the cutoff points is affected by three free energy quantities: that of the adsorption of the agent to the anesthetic "site" (f(sl,site)), that of the perturbation of the site (f(ll,site)), and that of the evaporation of the agent from its pure condensed phase (Deltamu degrees (evaporation)). This outcome indicates that the cutoff cannot be attributed to a single parameter. In addition, the analyses that attribute the cutoff to the failure of compounds to obey the much-used Meyer-Overton correlation will have to be amended. This article shows that cutoff results can be used to elucidate the structure of a site.

The goal of this study was to identify and characterise the major allergen(s) of sesame seed. Detection of specific IgE to sesame proteins was performed with Pharmacia CAP System and Western blotting, after separation of sesame proteins by SDS-PAGE, using sera from 28 subjects diagnosed as allergic to sesame. The major allergen was separated by gel filtration chromatography and identified by selective proteolysis followed by peptide sequence analyses, employing electrospray-ionization mass spectrometer. Twenty-four of the 28 subjects had sesame-specific IgE. A 14 kDa protein belonging to the 2S albumin family was recognised by 22 of the 24 sera used. Subjecting the 14 kDa after HPLC separation to proteolysis with Lys C yielded 3 peptides, but only one reacted positively in the dot blot test. This peptide, corresponds in the whole protein chain to residues 24-94. The reactivity of the 14 kDa protein with most of the sera indicates that this is the major sesame allergen, later identified as 2S albumin precursor; and its peptide which reacted positively in the dot blot test evidently contains an epitope(s). Some minor sesame allergens, of higher molecular weight, were also revealed.
