Adult-onset egg allergy is rare compared to child-onset egg allergy, and the component-resolved diagnosis test is effective in evaluating food allergy. We herein report a 24-year-old woman with late-onset egg-yolk allergy diagnosed as bird-egg syndrome. The prolonged exposure to pet parrots' dander or dropping through the respiratory system caused sensitization to the Gal d 5 component and resulted in a cross-reaction to egg yolk. Since the patient was suspected of the syndrome by her history, the skin prick test, ISAC ImmunoCAP, and serum ImmunoCAP test were performed. By confirming Gal d 5 component by ISAC ImmunoCAP, the patient was diagnosed with the syndrome. In patients with newly adult-onset food allergy, the clinician must identify the environmental conditions which can cause cross-sensitization and perform the causative component test.

PURPOSE: The objective of this study was to observe the neurodevelopmental outcomes of the surviving very low birth weight infants (VLBWIs) and to identify the perinatal risk factors having influences on to poor neurodevelopmental outcomes . METHODS: The VLBWIs weighing 500 to 1,499 g at birth who had survived to discharge from one NICU during about a 2 year period were followed-up and assessed with using the Baley Scales of Infant Development-Second Edition (BSID-II) test and neurologic examinations when the infants corrected age was between 12 and 24 months. Developmental delay was defined as a MDI less than 70 or a PDI less than 70. The birthweight specific rates of developmental delay and cerebral palsy were examined. The perinatal data were retrospectively collected from the medical records to identify peinatal risk factors that had an influence on poor neurologic outcomes. RESULTS: Thirty three (42.9%) of the 77 VLBWIs were assessed with the BSID-II and neurologic examination, when their corrected age was between 12 and 24 months. The rate of developmental delay and cerebral palsy in the assessed infants was 15.2% and 21.2%, respectively. Extremely low birth weight infants (ELBWIs) had high rates of developmental delay (30.8%) and cerebral palsys (30.8%). Maternal old age (>35 years, odds ratio=18.0, 95% CI, 1.2-262.7, P=0.035) and periventricular leukomalacia (PVL, odds ratio=12.6, 95% CI, 1.1-148.1, P=0.044) were independently associated with developmental delay and cerebral palsy, respectively. CONCLUSION: Significant poor neurodevelopmental outcome for the VLBW infants needs a more extended follow-up study for development, and especially for the ELBWIs.

PURPOSE: To report on lessons learnt in the management of primary invasive penile cancer in a major tertiary hospital in Australia. MATERIALS AND METHODS: Medical records for all patients who underwent surgery for primary invasive penile cancer between January 2000 and January 2011 were obtained. Patient demographics, clinical status of inguinal node, cancer stage and clinical outcomes were reviewed. All patients were followed up for a minimum of 48 months postoperative unless patient deceased within the first 48 months from the time of penile cancer surgery. RESULTS: Over the 11-year period, a total of 23 cases of invasive penile cancer were identified. Partial penectomy was the most common form of organ preserving surgery and the majority of patients have pT1b disease. Of the 9 patients with clinically palpable inguinal nodes, 7 patients were diagnosed with pN3 disease following inguinal lymphadenectomy. The Kaplan-Meier cancer-specific survival at 72 months showed decreasing survival based on tumour stage (83% in pT1, 79% in pT2, and 64% in pT3 disease) and nodal disease (100% in node negative, 50% in superficial inguinal lymphadenopathy, and 38% in patients with deep inguinal and/or pelvic lymphadenopathy) (p=0.082). The Kaplan-Meier cancer-specific survival revealed statistically significant difference in survival outcome in patients with local recurrence vs. systemic metastasis disease (33% vs. 17%, p=0.008). CONCLUSIONS: The presence of high risk features such as tumour stage, lymph node involvement and distant metastasis carries a significant higher risk of death and tumour recurrence in patients with penile cancer and inguinal lymph node metastasis.

10.Inhibition of Vascular Endothelial Growth Factor Induced Corneal Angiogenesis by Antibody to Intergrin beta3 Subunit.

Vascular cells respond to multiple cytokines, they also express a variety of integrin adhesion receptor. A number of the vascular cell integrins are functionally and structurally homologous, suggesting some level of biologic redundancy. We investigated the importance of alphavbeta3 function during vascular endothelial growth factor(VEGF) induced corneal angiogenesis by examining the effects of 9D491, a monoclonal antibody against beta3 that blocks alphavbeta3-mediated cell adhesion to vitronectin and fibrinogen. A hydrogel disk containing 500ng of VEGF was implanted into the superior corneal stroma of each of twelve New Zealand white rabbit eyes. Each eye also received a second hydrogel disk placed adjacent of the first, randomized to contain either 2.6microgram of 9D491 mAb(n=6) or 6E10, an irrelevant antibody of the same isotype, (n=6). Both disks were positioned 1.2mm from the superior limbus. Eyes were examined daily under a streomicroscope by two masked observers and assigned an angiogenesis score based on number and length of new blood vessels. On days 5 through 7 postimplantation, angiogenesis scores were not significantly lower in eyes treated with anti-alphavbeta3 mAb (averaged score=21.6) as compared to eyes treated with 6E10 (averaged score=24.0) (p<0.2, Wilcoxon rank sum test). In a rabbit corneal pocket assay, monoclonal antibody to beta3 could not inhibit corneal angiogenesis induced by VEGF.
