Histological results

Like the in vitro studies, the in vivo degradation of the TMC-CL copolymers containing 89% CL showed no change in shape or size after one year. As the degradation of the TMC-CL copolymers was so slow, a mature fibrous capsule remained throughout the year. Histological results of the TMC-CL copolymers were similar to those obtained from TMC-DLLA or other commonly used biodegradable polymers.

Other authors have confirmed these histological results after 15-20 years and even talk about permanent results in some patients. In 1985, Kligman showed that dermal reconstruction lasts for 20 years at least and that the risk of cancer is reduced. Clinically, the rejuvenated appearance of the skin can be maintained for a great many years (Figure 26.4). 

Liver biopsies performed in patients with chronic HBV infection are classified as chronic persistent hepatitis, chronic active hepatitis, and cirrhosis. Histologic results do not correlate with symptoms and often patients are asymptomatic until the development of cirrhosis. " Cirrhosis is manifested by interlacing strands of fibrous tissue with nodules of regenerating cells resulting in a characteristic small and knobby-appearing liver. This form of injury is irreversible and can be exacerbated by heavy alcohol consumption and concomitant infection with HCV or HIV. Hepatic decompensation as a result of cirrhosis includes ascites, jaundice, variceal bleeding, and hepatic encephalopathy. The 5-year risk of decompensation after the development of cirrhosis is estimated to be 20%. ...

Histological results revealed no damage to the intestinal tract which had been in contact with the immobilized enzyme preparation. Tissues studied included the kidney, thyroid, stomach, duodenum, pancreas, jejunum, ileum, cecum, colon, and rectum.

Virtual endoscopy has several limitations, primarily concerning the inability to detect flat or small lesions or to obtain histologic results. An additional limitation is related to ionizing radiation if CT is used, hut because acquisition time is short and so much more useful information is obtained, this disadvantage is negligible.

The success rate of dental implants increased dramatically during the 1980s [9]. Improved materials, selection of appropriate materials, and advanced technology have resulted in an improved implant/bone interface attachment that is responsible for the increased success. Success of dental implants is measured by the absence of mobility, no ra-diolucency between the bone and implant, and no other adverse symptoms or problems. The most successful dental implant today is the endosseous implant where the implant is anchored into the bone and osseointegrated. Success rates can be as high as 95 % over a five-year period Titanium and Ti-6Al-4V are the most widely used materials for the implants. The effects of surface treatment on the surface oxides of titanium have been shown [72,73]. Titanium was the material of choice for Branemark, who correlated the dental implant surface preparation and purity with the histology results of the interfacial bone [74].
