Protesi per ernia iatale a forma di A in materiale composito (polipropilene + politetrafluoroetilene)
No full textCAMPO DI APPLICAZIONE: MEDICO.
Il suo impiego e' nella terapia chirurgica dell' ernia iatale. Può essere ugualmente impiegata sia in chirurgia tradizionale “aperta”, che in chirurgia laparoscopica. Si tratta di una protesi di materiale biocompatibile composta da uno strato di polipropilene ed uno di politetrafluoroetilene saldati insieme. Tale protesi è sagomata in forma di “A” poiché presenta:
- un orifizio centrale (Fig.1.a) di cm.2,5 di diametro,
- una incisione lineare (Fig.1.b) della protesi stessa,
- un'incisura (Fig.1.c) sul lato inferiore della protesi,
- margini superiori arrotondati,
- un lato maggiore (Fig.1.d) che misura 7 cm,
- un lato minore (Fig.1.e) che misura 6 cm.
Lo spessore della protesi è uniforme in tutte le parti e misura 0,1 cm
Maxillary sinusitis and respiratory health in medieval Tuscany
No full textChronic maxillary sinusitis is recognized as new bone formation indicating long-term inflammation of the soft tissues of the sinuses whose origin can be either odontogenic or environmental (e.g. due to poor air quality, indoor conditions and allergies). Bone modifi- cations within the sinuses related to chronic inflamma- tory process are rarely attested in human skeletal re- mains owing to their incidental discovery, mostly when post-mortem breakages occur allowing to observe the internal pneumatic cavities.
As part of a preliminary study, a total of 113 individu- als coming from the Medieval rural cemetery of Pieve di Pava (10th-12th centuries AD) situated in Tuscany (central Italy) were examined to investigate the ori- gin of maxillary sinusitis. Both maxillary sinuses were available for examination in 110 individuals and only one sinus in 3 individuals. Eight males and 12 females were affected by maxillary sinusitis (17.7%, N = 113). Osseous alterations, represented by spicules, plaque- like formation and lobules, were bilaterally present in 25% of the male subsample (n = 8) and in 75% of the female subsample (n = 12) with statistically significant difference. Statistical difference was also assessed when compared the frequency of teeth and/or alveo- li affected by dentoalveolar diseases between sexes, with males greater influenced than females. In order to investigate the odontogenic role in the onset of chron- ic inflammation, co-occurrence of maxillary sinusitis and dentoalveolar diseases in the same sinus was ob- served in more than half of the individuals affected (11 out 20) with no statistical difference between sexes.
It can be presumed that absence of statistically sex-re- lated difference is likely due sample size effect; in this respect, future enlargement of the osteological sam- ple might potentially help in clarifying the contribution of dentoalveolar diseases in the expression of maxillary sinusitis
Prenatal rectal perforation: an unsuspected cause of isolated ascites
No full textIn fetal intestinal perforation, inflammation leads to production of ascites. Small bowel is usually involved by perforation with the distal ileum the most frequent site. We report the first case of prenatal perforation of the intraperitoneal part of the rectum, which presented as severe ascites at a 37 weeks' gestation antenatal ultrasonography. As none of the reported causes of intestinal perforation were identified in our case, its etiology remained idiopathi
