Balaenophilus manatorum in Debilitated and Bycatch-Derived Loggerhead Sea Turtles Caretta caretta from Northwestern Adriatic Sea.

Balenophilus manatorum (Copepoda: Harpaticoida) is one of the few components of the epibiontic fauna of Caretta caretta that show a "true" parasitic association with their host. From rrosive to ulcerative cutaneous lesions may seldom appear as a consequence of the copepod feeding on keratin on turtles' skin. Debilitating Turtle Syndrome (DTS) is the final outcome of a chronic insufficient assumption of nutrients, generally occurring with the impairment of immune functions and high epibiota burdens. In this survey, the presence of B. manatorum in C. caretta from the Northwestern Adriatic Sea was investigated and the relation between infection indices and the co-occurrence of DTS was studied. Clinical examination was performed at the time of rescue, including routine hematological assessment; external parasites were isolated mechanically from turtles' skin and morphologically identified through observation with an optic microscope and SEM. Ten turtles were classified as affected by DTS, all of them being small juveniles with typical clinical and clinicopathological presentation. A higher prevalence, abundance, and density of infection were found in turtles affected by the syndrome. The presence of massive skin coverage by the burrowing barnacle Pletylepas hexastylos prevented a proper evaluation of the pathology associated with B. manatorum in turtles affected by DTS. In any event, eventual skin damages caused by the parasite may represent a port of entry for secondary infections in such immunocompromised animals. Therefore, infection by B. manatorum should not go overlooked in debilitated turtles and should be opportunely treated.

Allergic diseases and their impact on quality of life.

OBJECTIVE: To review the results of studies that have evaluated the impact of allergic diseases on patients' health-related quality of life (HRQL). DATA SOURCES: We performed a MEDLINE search of the literature published between January 1990 and May 2006 (English language only) on HRQL and allergic diseases. STUDY SELECTION: Representative studies that used validated questionnaires that assessed the effect of allergic diseases on HRQL were selected for inclusion in this review. RESULTS: Allergic diseases can deeply interfere with patients' HRQL, with detrimental effects on the physical, psychological, and social dimensions of life. Numerous validated questionnaires that are now available can easily be adopted; most of them are specifically developed for rhinitis and asthma. CONCLUSIONS: HRQL has become an increasingly important aspect in outcome evaluation in health care research, providing a more comprehensive approach to the patient and proving that nowadays we cannot renounce this tool. Most of the studies evaluate patients with respiratory allergy. Further studies are needed to explore HRQL in other allergic conditions (urticaria, food allergy, sting allergy, drug allergy) by means of specific, validated questionnaires.

Overview of novel therapeutic targets for asthma and chronic obstructive pulmonary disease.

Obstructive lung diseases, in particular asthma and chronic obstructive pulmonary disease, are a worldwide health problem that is increasing in incidence. While significant progress has been made in the control of symptoms, further advances must be made in modifying the clinical situation in terms of disease progression. Numerous pathogenetic studies have demonstrated that inflammatory responses play a crucial role in the development of chronic lung obstruction, while current molecular findings have provided a myriad of new and promising therapeutic targets. The aim of this article is to provide an overview of clinically and pharmacologically relevant targets for asthma and chronic obstructive pulmonary diseases, considering currently investigated therapeutic approaches.
