AbstractWe report the first case of early postoperative infection after a medial hemiarthroplasty of the knee with a customized ConforMIS iForma™ interpositional device. The infection was treated successfully by revision surgery with implant removal and antibiotic therapy. Despite the additional diagnosis of rheumatoid arthritis that did not affect the treated knee, the preservation of bony and ligamentous structures enabled a successful re-implantation of another iForma™ implant 9 months later with good clinical results at follow-up examination 1 year postoperatively. This is very much in contrast to the extensive and complex revision surgery, with significant bone loss, in patients with infected unicompartmental or total knee arthroplasties. The iForma™ device may be an alternative treatment option in early and moderate unicompartmental arthritis of the knee, with easy revision with the same type of implant in the rare case of infection.

Most malignant tumors of the penis are squamous cell carcinomas (SCC), being divided in 2 groups, one human papillomavirus (HPV)-related and another non-HPV-related, with lymphoepithelioma-like carcinoma (LELC) being one of the rarest HPV-related SCC. In this article, we report a case of a 50-year-old man who presented testicular swelling and pain for the past 3 months. A penile mass was identified, and the patient was submitted to a total penectomy. The penectomy specimen showed an ulcerated lesion at the glans reaching the cavernous bodies. Microscopic examination showed undifferentiated epithelial cells with syncytial growth pattern mix with a dense lymphoplasmacytic infiltrate, consistent with LELC. The tumor cells expressed p16 and all 3 different clones of PDL1 (22C3, SP263, and SP142). The patient is alive and well with a follow-up of 3 months. To our knowledge, this is the third LELC of the penis reported in literature and the first case reported with PDL1 expression.

<p class="abstract">Teratomas are embryonal neoplasm arises from totipotent germ cells. They are having tissues from all the three blastodermic layers. There are various locations of congenital teratoma. Naso-oropharyngeal site teratoma are either sessile or pedunculated. We describe a rare case of laryngeal teratoma in a five years old patient presented with change in voice and breathing difficulty. On flexible laryngoscopy, it appeared like supraglottic cyst but on CT scan it was confirmed as teratoma. Pre-operative tracheostomy and transoral carbon dioxide laser assisted excision done. Histopathological examination showed osteoid trabeculae, chondroid tissue with loose myxoid islands and adipose tissue. No recurrence of tumor on 18 months follow-up. This is the first case report of pediatric larynx teratoma reported in present century.</p>

This study analyzes the long-term results of 23 metal ring supports used in revision surgery since 1979. Only a metallic ring and a cemented cup were used in this series. Bone grafts and cementless cups were excluded from this study. One deep infection was excluded from the follow-up study. In the 22 cases analyzed, the mean follow-up period was 10 years for all cases and 12.2 years for unrevised cases. Bone defects according to the AAOS classification were: Grade 1, 1 case, Grade 2, 1 case, Grade 3, 10 cases, and Grade 4, 10 cases. A Müller ring was indicated in an anterior or medial wall defect (12 cases) and a Burch-Schneider ring was indicated in an anterior or posterior column defect or in pelvic discontinuity (10 cases). The clinical results were good in 8 cases, fair in 8 cases, and poor in 6 cases. Six cases were rerevised or removed, resulting in a total cumulative probability of rerevison or removal of 23.8% after 10 years according to the Kaplan-Meier analysis. Postoperatively, 18 cases had neutral rings, 2 cases had horizontal rings, and 2 cases had vertical rings. Radiological cup migration was found in 12 cases, resulting in a total cumulative probability of migration of 56.8% after 13 years according to the Kaplan-Meier analysis. Changes in the acetabular angle were present in 2 cases, vertical migration in 12 cases, and medial migration in 10 cases. Our data suggest that the metal ring and cemented cup alone could be used for salvage surgery in elderly patients and in low-demand patients. Possibly, adding bone graft could improve these results.
