An unusual thoracic localizations of Erdheim- Chester disease: A case report.

Erdheim- Chester disease is a rare non- Langerhans cell histiocytosis that usually involves the bones, heart, central nervous system, retroperitoneum, eyes, kidneys, skin and adrenals. Lungs are affected in up to one-half cases; at CT scan various patterns are described: interstitial disease, consolidations, micronodules and microcysts, with or without pleural involvement. We presented a case of a 59 year-old man with unusual intrathoracic manifestation of Erdheim- Chester disease. Singularities of our report are the lonely thoracic involvement at the onset of the disease and a histiocytic lesion in the posterior mediastinum.

Component resolved diagnosis in real life: the risk assessment of food allergy using microarray-based immunoassay.

BACKGROUND: The development of component-resolved diagnostics constitutes a potential breakthrough in food allergy testing, as detection of specific IgE (sIgE) to individual allergens may make it possible to establish the risk of a mild versus severe reaction. OBJECTIVE: To compare allergists' risk assessment based on the current decision making process with that of virtual allergen-oriented risk assessment through microarray-based immunoassay. METHODS: An observational, real-life study was performed on 86 adults with food allergy. The prescription of epinephrine was the surrogate marker of a severe reaction. In the same patients, the prescription of epinephrine based on the current decision making of the allergist and the independently established allergen-oriented risk assessment determined by microarray-based immunoassay were compared. RESULTS: Fair degree of agreement between the specialists' risk assessment and that of the microarray-based immunoassay (k index 0.372 (95% CI: 0.185- 0.559) p < 0.001) was documented. Three causes of discrepancy emerged: the poor sensitivity of the allergen microarray-immunoassay (51.9%), the differences in risk assessment established by the specialist and the microarray-immunoassay (33.3%), the non-inclusion of the causative allergen in the microarray-immunoassay platform (14.8%). CONCLUSION: Improvement of the diagnostic accuracy of microarray-immunoassay, combined with marrying its results to clinical information, could one day soon lead to changes in clinical practice in food allergy.

Intraoperative anaphylaxis: a case report of allergy to ranitidine.

We report the case of a 18-year old male who developed intraoperative anaphylaxis. The presence of specific IgE to ranitidine was documented This case confirms the possibility of anaphylaxis at first exposure.

Eating disorders: a threat for women's health. Oral manifestations in a comprehensive overview.

The incidence of eating disorders has progressively increased over the last several years, mainly affecting both the health and quality of life of young women. Such disorders are primarily an outlet for manifest psychic suffering and secondarily, they jeopardize the integrity and function of multiple organ systems resulting in significant morbidity and sometimes, life-threatening outcomes. The complex emerging interplay of etiopathogenetic factors poses many challenges in their prevention and management, which is further complicated by a reluctance by patients with eating disorders to seek medical evaluation and treatment. Recognition of the oral manifestations is important because these signs and symptoms can provide insights about disease progression and parallel general health and psychic status. Oral health care providers may be one of the few providers contacted by this patient population seeking recall prophylaxis or urgent dental care. Thus, improving understanding and knowledge of both general medical aspects of eating disorders and their oral manifestations could be of great impact in elevating the attention of health providers towards this group of very debilitating disorders and, consequently, improving their overall prognosis. In this paper we will review and discuss all these aspects.
