Background & Aims Little is known about risk of upper gastrointestinal bleeding (UGIB) in patients failed by Helicobacter pylori eradication therapy. We investigated the effects different time until retreatment, after failure initial H therapy, on subsequent UGIB. Methods performed a territory-wide retrospective cohort study 70,518 with infection who had received their first course clarithromyc...

persistent microorganisms in the root canal are known to cause endodontic treatments failure. overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions. retrieval of overextended gutta-percha with a nonsurgical approach can prove to be a challenge. this case describes the nonsurgical management of a large periapical lesion associated with ove...

Aim- To evaluate the removal of gutta percha by hand file system, rotary system and reciprocating from root canals using CBCT. Materials Method: Root 42 extracted human mandibular premolars were prepared ProTaper Universal then obturated. filling quality was confirmed on CBCT images. Specimens divided into 3 groups (n = 14) according to used for removal, group 1: H File, 2: MTwo retreatment fil...

A total of 1300 endodontic patient charts were analyzed for factors that may have contributed to the failure of the original treatment or the success of the retreatment. Of those surveyed, 667 had recall information of 6 months or more and were used to consider success rates. The remaining cases were analyzed for other information. The findings were tabulated and analyzed by computer for signif...

The use of brachytherapy--and to a lesser extent, external-beam radiotherapy--in the management of locally recurrent breast cancer following ipsilateral breast tumor recurrence (IBTR) followed by repeat breast-conservation surgery and irradiation is currently an area of intense study. The current cosmetic scoring system is inadequate to score the outcome resulting from retreatment because it do...

When root canal therapy is done according to accepted clinical principles and under aseptic conditions, the success rate is generally high. However, it has also been reported that 16% to 64.5% of endodontically treated teeth are associated with periapical radiolucent lesions. There are great variations among clinicians when suggesting treatment of these failed endodontic cases. This article wil...

This article reports non-surgical endodontic retreatment of two patients with persistent or recurrent periapical lesions, who had previously undergone surgical and non-surgical endodontic therapy respectively. It further discusses and reviews the relevance of classification of periapical lesions, the explanation behind healing of periapical lesions by endodontic therapy alone, causes of persist...

This study was carried out to determine factors affecting tuberculosis retreatment defaults in Nanded, India. All patients registered as tuberculosis retreatment cases (n = 107 excluding deaths during treatment) were interviewed by home visits. Their sociodemographic characteristics and treatment history were recorded and later compared with their treatment outcomes. Among the patients register...

The authors of 4 National Institutes of Health-sponsored antibiotic treatment trials of patients with persistent unexplained symptoms despite previous antibiotic treatment of Lyme disease determined that retreatment provides little if any benefit and carries significant risk. Two groups recently provided an independent reassessment of these trials and concluded that prolonged courses of antibio...
