Unusual localization of pennella sp. In swordfish (xiphias gladius) hearts
The genus Pennella comprises hematophagous parasites of marine aquatic species, including cephalopods, marine mammals, and pelagic fish. Nine species have been officially included in the genus Pennella plus another six species inquirendae. They are most often found in the host’s musculature, without penetrating internal organs. For the present study, 83 hearts from swordfish (Xiphias gladius) caught in the Mediterranean Sea were sampled and immediately fixed in formalin for histopathological analysis. In total, 10 (12.05%) hearts were found to be parasitized by copepods of the genus Pennella. Macroscopically, there was mild-to-severe fibrinous pericarditis with atrial wall thickening and multiple parasitic nodules. Histologically, the parasitic nodules were surrounded by an inflammatory-necrotizing reaction. Parasitic infestation by Pennella spp. is common in pelagic fish and in swordfish, in particular. Here, however, we report atypical cardiac localization. A future area of focus is the evaluation of cardiac Pennella spp. infestation by histopathology and genetic identification of the parasites

Pennella benzi Hogans, 2017, sp. nov.
Pennella benzi sp. nov. (Fig. 6) Host. Escolar (Lepidicybium flavobrunneum Smith, 1843) Type Locality. Holotype and paratype 1: Host caught in the northwest Atlantic (no specific locality) Paratype 2: Host caught off coastal North Carolina, northwest Atlantic Site of infestation. Embedded in deep musculature, along base of dorsal fin Etymology. The species is named for Dr. George W. Benz, in honor of his contributions to the study of parasitic Copepoda Type material. Holotype: United States National Museum (USNM) 180162; Paratype 1: USNM 180163; Paratype 2: Fisheries and Oceans Canada, Atlantic Reference Center (ARC), ARC 29529 Description. Ovigerous female (Fig. 6 a, b): cephalothorax bulbous, spherical, apical end flattened, armed with numerous roughly spherical cephalothoracic papillae of various sizes (Fig. 6 d). Configuration of papillae unorganized and different between all three specimens. Three holdfast horns radiating from below cephalothorax: two lateral, and one shorter dorsal horn bifurcate at tip (Fig. 6 c, i). Thoracic neck tubular, elongate, posterior end enlarged to form anterior end of trunk. Trunk one-half length of entire parasite, cylindrical, with parallel sides. Trunk tapering abruptly at its posterior end to form the abdomen. Abdomen about one-half length of trunk, annulated, with rounded dorsal surface and flattened ventral surface. Abdominal plumes arising from ventral surface of abdomen in two rows; individual plume (24-28) sets arise from a single stem and then branch repeatedly to form a mass of digitiform plumules (Fig. 6 h). Number of plumules per set variable. Genital complex (Fig. 6 g) at posterior end of abdomen, exhibiting two small oviduct orifices on ventral surface. Egg strings paired, filiform, about 1.5x length of each parasite, eggs uniseriate. First antenna (Fig. 6 e), observed clearly on one specimen only (paratype 2), two- segmented. Apical armature of 9 setae of various lengths. Setae of middle portion shorter and more numerous. Second antenna (Fig. 6 f), distinctly three-segmented; terminal segment with prehensile large re-curved hook which closes on a blunt, distal spine; small spine at base of hook. Buccal complex (mouth), mandibles, first and second maxillae and maxillipeds not observed on any specimen. Swimming legs (4) reduced to sympods only, rami lost or atrophied and not observable. Total length (anterior end of cephalothorax to posterior end of abdomen) of three specimens: 131, 157, 162. Remarks. This new species is erected based on a newly collected specimen and on two others previously assigned to Pennella filosa also collected from the escolar (oilfish) in the northwest Atlantic (Benz & Hogans 1993). Benz & Hogans (1993) considered their two specimens to be phenotypic variations of P. filosa, but finding a new and third specimen on the same species of host shows P. benzi sp. nov. to be a different species than P. filosa which it closely resembles. Pennella benzi sp. nov. has several features which are unique and distinguish it from P. filosa: P. benzi sp. nov. is a somewhat smaller parasite (150 mm) than P. filosa (180mm); a unique host (escolar) which has not previously been recorded as parasitized by any other Pennella sp.; dorsal horn configuration: all three known specimens of P. benzi sp. nov. have a bifurcate dorsal horn, a feature never previously reported within the genus. Pennella benzi sp. nov. possesses a three-segmented second antenna; P. filosa exhibits two segments on this appendage. It can be easily distinguished from the other large Pennella found on fish, P. instructa, based on the cepahlothoracic papillae (not arranged in distinct groups) and possessing a dorsal horn (not found in P. instructa).Published as part of Hogans, W.

La ricerca in psicoterapia: il confronto con la relazione e l'inconscio
Nel capitolo viene affrontato il tema della ricerca in psicoterapia. In particolare si analizza la distanza riscontrata in letteratura tra le valutazioni dei possibili giudici degli esiti del processo psicoterapeutico e la difficoltà nel coniugare la prospettiva del clinico, del paziente, del valutatore esterno in una rappresentazione condivisa. Viene quindi argomentata l’importanza di esplorare la prospettiva dei pazienti e in modo particolare la loro rappresentazione del percorso terapeutico una volta che si sia concluso, al fine di orientare in modo più puntuale ed efficace la prassi clinica. Si dà infine conto di un disegno di ricerca volto a perseguire gli obiettivi sopra delineati
