Ten skeletally immature patients were treated with an arthroscopic-assisted anterior cruciate ligament reconstruction with bone-patellar tendon bone autograft (compass, 50-558; holes, 7-9 mm). Radiological assessments (standard radiograph), Orthopä dische Arbeitsgruppe Knie (OAK) score and KT 1000, were conducted on all patients, 1 year after surgery. Skeletal maturity had been reached by all patients and no complications were observed. All patients returned to their preinjury sport level. Drilling more vertical tunnels when bone-tendon-bone autograft was chosen to avoid partial epiphysiodesis and offers good functional and isometric results.

Periprosthetic joint infection (PJI) is one of the most challenging complications a surgeon has to face after prosthetic replacement of a joint and one of the most devastating complications for the patient. During the 2018 International Consensus Meeting (ICM) in Philadelphia a numerical diagnostic tool was proposed. Contraindications to single stage revision include significant soft tissue injury with the inability to provide soft tissue cover, the presence of unknown or multi resistant organisms, lack of access to appropriate antibiotics or lack of appropriate expertise. Two stage revision surgery is indicated in these situations. Insall et al. described the surgical two-stage prosthetic revision technique in 1983: the in situ prosthesis is removed, a thorough debridement of bone and soft tissue is performed, an interval spacer is inserted, antibiotics administered. The 2 nd stage of definitive reconstruction is performed once the infection is deemed to have resolved. The interval between stages can range from 6 weeks to several months. PJI are very challenging for every surgeon skilled in prosthetic surgery. It’s necessary to make an exact preoperative diagnosis and to treat them with the proper technique. Further studies are needed to establish the perfect timing between the two stages, the duration of the antibiotic therapy and to standardize the diagnostic chart.

In a prospective study, 17 Brazilian patients with parenchymatous neurocysticercosis were monitored for a period of 12 months after treatment with praziquantel. Taenia solium-specific IgG antibodies, interleukin-1 beta (IL-1 beta), tumor necrosis factor alpha, neopterin, and soluble interleukin-2 receptor (sIL-2R) were measured in serum and CSF before starting the therapy, on the last day of treatment, 5 weeks after treatment, and 3, 6, and 12 months after treatment. The most common symptoms and signs found in patients before treatment were headache, neck stiffness, and seizures. Six months after commencement of therapy, 13 of the 17 patients were free of complaints. Clinical normalization was paralleled by a significant decrease (p < 0.05) in the amount of intrathecally produced anti-T solium IgG 1 year after treatment. IL-1 beta was undetectable in serum at all times, whereas in the CSF it was within the normal range during the whole study period. The mean concentration of sIL-2R in the CSF was 65 kU/l (normal, < 50 kU/l) 5 weeks after treatment, whereas in all subsequent investigations sIL-2R was undetectable. The median CSF neopterin level was slightly elevated before treatment (6.8 nmol/l). One year after treatment, it had dropped by 69% (p < 0.001) to a median value of 2.1 nmol/l. The size of planimetrically measured focal cystic brain lesions on CT correlated with the amount of intrathecally synthesized anti-T solium IgG at the end of the study (r = 0.89, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

The most common elbow lesions found in pediatric practice are supracondylar fractures. We compared two groups of 34 patients each with a supracondylar humerus fracture grade III (Gartland classification). The first group was treated with percutaneous pinning with Kirschner wires, with patients in a supine position, sometimes preceded by transkeletal traction. The second group was treated with percutaneous pinning with Kirschner wires, with patients in a prone position, within 6 h of the trauma. No statistically significant differences with regard to clinical outcomes and neurovascular complications were revealed in the comparison. Therefore, we can state that both treatment techniques used are valid.
