Septic arthritis caused by Mycobacterium marinum.

The incidence of infection by Mycobacterium marinum is rising, mainly due to the increasing popularity of home aquariums. The infection typically manifests as skin lesions, with septic arthritis being a rare presentation form. The disease is difficult to diagnose even when there is a high clinical suspicion, as culture in specific media may not yield positive findings.

Simultaneous development of Dieterich disease and Freiberg disease.

Dieterich disease is an uncommon arthropathy of the hand, with few studies published. This lesion shares a similar etiopathogenesis with Freiberg disease, although the association of both conditions has only been described once. We report a 65-year-old man consulting for inflammatory pain in his right hand of 1 month's duration and also in his right foot of 4 months' duration.

Five-year results of implants inserted into freeze-dried block allografts.

Purpose: The purpose of this study was to evaluate the outcome after 5 years of allografts as bone growth material and success of implants inserted in fresh-frozen allograft bone.

Materials And Methods: A total of 20 patients were operated and 41 onlay block freeze-dried allografts (calvarial and iliac crest) were inserted for bone augmentation. A total of 64 dental implants were performed in a two-stage procedure.

Trends in colorectal cancer survival following the 2-week rule.

Objective: The 2-week rule has reduced waiting times for a specialist opinion among patients with a suspected malignancy. We aimed at assessing the effect of this rule on colorectal cancer survival.

Method: Patients diagnosed with colorectal cancer before (group 1) and after (group 2) the introduction of the 2-week rule were identified from a prospective database.

The clinical significance of the circumferential resection margin following preoperative pelvic chemo-radiotherapy in rectal cancer: why we need a common language.

Objective: The presence of microscopic tumour cells within 1 mm of the circumferential surgical resection margin (CRM) is the endpoint most strongly associated with local recurrence in rectal cancer and doubles the risk of developing distant metastases. Reporting on the CRM can monitor surgical quality assurance and over the past two decades has driven advances in surgical technique with the increasing use of total mesorectal excision. The aim of this review was to use the evidence from both phase II and phase III randomized trials of preoperative radiotherapy and chemoradiation in rectal cancer, to assess how often CRM involvement is currently documented and examine its utility as an early predictor of both disease-free and overall survival.
