Occupational allergic contact urticaria to tropomyosin from squid.

A cook's mate working in an Austrian restaurant reported acutely occurring urticarial skin lesions after processing and cooking squid. The prick-to-prick test with squid showed a ++ positive urticarial reaction. Elevated specific IgE antibody levels to squid, shrimp, and house dust mites as well as to tropomyosin from shrimp and house dust mite could be detected in the ImmunoCAP. By means of immunoblot and ELISA, a reaction to squid extract as well as increased IgE antibody levels to squid and tropomyosin from squid could be detected. The patient was diagnosed with a clinically and occupationally relevant type I allergy to squid with cross-reaction to tropomyosin of other invertebrates and therefore recognized as an occupational disease.

Management of malignant pleural mesothelioma - part 1: epidemiology, diagnosis, and staging : Consensus of the Austrian Mesothelioma Interest Group (AMIG).

Malignant pleural mesothelioma is a rare malignant disease that in the majority of cases is associated with asbestos exposure. The incidence in Europe is about 20 per million inhabitants and it is increasing worldwide. Initial symptoms are shortness of breath, pleural effusion, cough, and chest pain. The typical growth pattern is along the pleural surface; however, infiltration of the lung and/or mediastinal and chest wall structures can occur in a more advanced stage. Ultimately, distant metastases outside the chest can result. Several histological subtypes of pleural mesothelioma exist, which must be differentiated from either benign diseases or metastases in the pleural space by other tumor entities. This differential diagnosis can be very difficult and a large panel of immunohistochemical markers is required to establish the exact diagnosis. The standard procedure for confirming the disease and obtaining sufficient tissue for the diagnosis is videothoracoscopy. Full thickness biopsies are required, while transthoracic needle puncture of pleural fluid or tissue is considered to be insufficient for a cytological diagnosis. Complete and detailed staging is mandatory for categorization of the disease as well as for therapeutic decision making.

Management of malignant pleural mesothelioma-part 2: therapeutic approaches : Consensus of the Austrian Mesothelioma Interest Group (AMIG).

Treatment of malignant pleural mesothelioma (MPM) depends on performance status of the patient, tumor stage, and histological differentiation. Chemotherapy (CHT) can be administered as first- and second-line treatment in unresectable MPM or as neoadjuvant or adjuvant treatment before or after surgery. A combination of an antifolate and platinum-based CHT is the only approved standard of care. Several targeted and immunotherapies are in evaluation and further studies are warranted to determine the therapeutic value of these new treatment options. Radiotherapy (RT) can be considered either as adjuvant treatment after surgery or for palliation of pain-related tumor growth. Recent data support the use of RT in a neoadjuvant setting. Macroscopic complete resection by pleurectomy/decortication (P/D) or extrapleural pneumonectomy (EPP) is indicated in selected patients with good performance status. Surgery should only be applied as part of a multimodality treatment (MMT) in combination with chemo- and/or radiotherapy. In a large number of cases, palliative attempts are needed to improve quality of life and to achieve symptom control.

Management of malignant pleural mesothelioma - part 3 : Data from the Austrian Mesothelioma Interest Group (AMIG) database.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare but aggressive tumor originating from the pleural cavity with a strong link to previous asbestos exposure. In order to determine the demographics, diagnostics, therapeutic strategies, and prognosis of MPM patients in Austria, the Austrian Mesothelioma Interest Group (AMIG) was founded in 2011. In this report the data from the AMIG MPM database collected to date are reported. METHODS: A prospective observational registry was initiated, including patients with histologically verified MPM diagnosed and treated at specialized centers in Austria. Patient inclusion started in January 2011 and follow-up was completed until September 2015. RESULTS: A total number of 210 patients were included. There were 167 male and 43 female patients with a mean age of 67.0 years (SD ± 11.3) at the time of diagnosis. Asbestos exposure was confirmed in 109 (69.4 %) patients. The histological subtype was epithelioid in 141 (67.2 %), sarcomatoid in 16 (7.6 %), biphasic in 28 (13.3 %), and MPM not otherwise specified in 25 (11.9 %) patients. Of the patients, 30 (14.3 %) received best supportive care (BSC) only, 71 (33.8 %) chemotherapy (CHT) alone, four (1.9 %) radiotherapy (RT) alone, 23 (11.9 %) CHT/RT, two (0.9 %) surgery alone, and 76 (36.2 %) curative surgery within a multimodality treatment (MMT), which was more frequently performed for patients younger than 65 years and with early-stage disease (I + II). Median overall survival (OS) was 19.1 months (95 % CI 14.7-23.5). The 1­, 3­, and 5­year OS rates were 66 %, 30 %, and 23 %, respectively, and OS was significantly better in patients undergoing surgery within MMT (5-year survival 5 % vs. 40 %, p = 0.001). CONCLUSION: Patients with earlier disease stages, younger age, good performance status, and epithelioid histology were more likely to undergo MMT including surgery, which resulted in a more favorable outcome.
