Recurrent prosthetic joint infection due to Salmonella enteritidis: case report and literature review.

Prosthetic joint infection (PJI) due to Salmonella spp. is rare. We report a case of a recurrent prosthetic infection with involvement of two joints in a 72-year-old man and review the literature. The review of all cases previously reported and our case shows that conservative approach using antibiotics alone is insufficient to cure the infection. Prolonged antibiotic treatment and two-stage reconstruction with the use of joint spacer is the best choice for the treatment. Salmonella spp. should be considered as a cause of PJI, especially in patients with previous infections caused by this microorganism.

Prosthetic hip infection due to Brucella melitensis: case report and literature review.

Prosthetic joint infection (PJI) due to Brucella spp. is extremely rare. We report the case of a prosthetic hip infection due to Brucella melitensis in a 51-year-old male patient. The initial presentation was a gluteal abscess. There was radiographic evidence of implant loosening. The patient was cured after prolonged treatment with streptomycin, rifampicin, and doxycycline, followed by 2-stage exchange of the prosthesis. Brucella spp. should be considered in the differential diagnosis of PJI in countries where brucellosis is endemic. The review of all cases previously reported shows that a conservative approach using antibiotics alone can be followed in patients without signs of implant loosening. In contrast, prolonged antibiotic treatment and prosthetic joint revision should be considered in patients with evidence of implant loosening.

Supracondylar fractures of the humerus in children.

Supracondylar fractures of the humerus need a precise treatment in order to obtain a satisfactory result because of the low bone remodeling associated with these injuries. It is important to use a systematic procedure for closed reduction and percutaneous fixation. A retrospective review of fractures treated using two K-wires from the lateral side was done in 77 patients with a mean age of 6.7 years (range, 1-13 years). Displacement of the fracture was classified as Gartland Type II in 39 patients (50.6%) and Gartland Type III in 38 patients (49.4%). The results according to Flynn criteria were excellent in 70 patients (90.9%), fair in three patients (3.9%) and poor in four patients (5.2%), with overall satisfactory results in 96.1% of the cases. In four patients there was secondary displacement of the fragments in internal rotation and three of these patients were operated on again, increasing fixation with a third K-wire either from the lateral or medial side. There were two nerve lesions (2.6%), and four patients (5.2%) had a pulseless pink hand that recovered when the fracture was reduced. In three patients (3.9%) infection developed. To obtain satisfactory results using this procedure, enough stability should be achieved, avoiding iatrogenic damage of the ulnar nerve.
