7.Bird-Egg syndrome diagnosed by ImmunoCap ISAC

Allergy, Asthma & Respiratory Disease 2023;11(3):161-163
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.

To evaluate the efficacy of oplyhexamethylene biguanide(PHMB) in Staphylococcus aureus (S. aureus) keratitis model, 10microliter of S. sureus bacterial suspension(1x10(5) colony-forming unit(cfu)/ml) were infected intrastromally into rabbit corneas. 18 rabbits were divided into three treatment groups : balanced salt solution (BSS) group(n=18 eyes), PHMB(0.02%, 200microgram/ml) group(n=9), cefazolin(40 microgram/ml) group(n=9). Topical antibiotic drops were given hourly starting at 24 hours after inoculation. A subconjunctival injection was given every 24 hours for the study duration(96 hours). The severity of keratitis was scored in masked fashion every 12 hours. Corneal buttons were excised and homogenized at the end of the study to determine viable bacterial counts. In the S. aureus keratitis model, there was no difference of clinical scores between BSS, cefazolin, PHMB group at 72 hours, and the number of viable bacteria recovered from the corneal button in log(10) cfu was 2.65+/-1.85, 3.30+/-0.85, 2.86+/-1.36, in BSS, cefazolin, PHMB group respectively. No differences in either clinical scores or bacterial counts were found between the PHMB and BSS groups. PHMB appears to be ineffective against S. aureus in this model of experimental keratitis.

A questionnaire on a variety of ophthalmic topics was made up and sent to 150 members of the Korean Society of Cataract and Refractive Surgery-[KSCRS] in May, 1996. Forty percent [60/150] responded within the deadline in June, 1996. As the contents of the questionnaire were almost identical to the ones prepared in the USA [1994, 1995] and in Japan [1994], the answer to the questionnaire could be compared with those gathered from the USA and Japan. Over half of the respondents [57%] were in their forties. The average number of operations done per month was 26. Cataract operation accounted for over 60% of the total operations in 34% of KSCRS members. And more than 76% of the cataract operation were done using phacoemulsification technique in 31% of the respondents. There were no difference in the preferred method of local anesthesia for the cataract surgery in Korea compare to the USA or Japan. And there was less likelihood of using peribulbar anesthesia and no suture technique in Korea compared to the USA. Sixty-one percent of the Korean ophthalmic surgeon implanted the intraocular lenses even before the patients were younger than 20 years old whereas, 82% of ophthalmic surgeon in Japan did only when the patients were older than 20 years of age. For radial keratotomy as a means of correcting myopia, 91% of the Korean respondents were not performing the procedure any more, while 45% of the American respondents abandoned it. Fifty four percent of the Korean respondents and 46% of the American respondents have been doing excimer laser photorefractive keratectomy. There was no statistical difference between the two. From the answers to the qustionnaire, we found that our results did not differ significantly from those of the USA or Japan and we believe that these results reflect the present trends of cataract and refractive surgeries in Korea.

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.
