Purpose To report 3 patients operated on using medial hip arthroscopic portals, describe the surgical technique and clinical outcomes. Methods Three medial portals were made, the first one at the posterior edge of the adductor longus muscle (posterior medial portal), the second one at the anterior (anterior medial portal) and the third at the posterior border of the adductor longus, 5 cm distal to the inguinal crease (distal posterior medial portal). The first case was an 8-year-old boy with a lytic lesion at the posteromedial region of the femoral neck suggestive of sub-acute osteomyelitis. The second patient was a 21-year-old male with a posteromedial femoral neck nidus. The third patient was a 42-year-old male with a posteromedial femoral neck cystic lesion. Conclusions The described portals allowed successful access to posteromedial femoral neck. There were no neurovascular lesions, infection, femoral head osteonecrosis, skin retraction or functional limitation related to the portals.

Avulsion injuries of the adductor longus muscle tendon are rare and a challenge to manage especially in athletes. There has been little published literature on the outcome of conservative and operative treatment for these injuries. We report the first case of an acute adductor longus avulsion injury which was surgically repaired in a professional equestrian rider. Return to full preinjury function was achieved at 3 months with surgical repair using 3 suture anchors.

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.

For networks with human-driven vehicles (HDVs) only, pricing with arc-specific tolls has been proposed to achieve minimization of travel times in a decentralized way. However, the policy is hardly feasible from a technical viewpoint without connectivity. Therefore, for networks with mixed traffic of HDVs and connected and autonomous vehicles (CAVs), this paper considers pricing in a scenario where only CAVs are charged. In contrast to HDVs, CAVs can be managed as individual vehicles or as a fleet. In the latter case, CAVs can be routed to minimize the travel time of the fleet of CAVs or that of the entire fleet of HDVs and CAVs. We have a selfish user behavior in the first case, a private monopolist behavior in the second, a social planner behavior in the third. Pricing achieves in a decentralized way the social planner optimum. Tolls are not unique and can take both positive and negative values. Marginal cost pricing is one solution. The valid toll set is provided, and tolls are then computed according to two schemes: one with positive tolls only and minimum toll expenditure, and one with both tolls and subsidies and zero net expenditure. Convergent algorithms are used for the mixed-behavior equilibrium (simplicial decomposition algorithm) and toll determination (cutting plane algorithm). The computational experience with three networks: a two-arc network representative of the classic town bypass case, the Nguyen-Dupuis network, and the Anaheim network, provides useful policy insight.

In this reporting period (November 2020-March 2021), five cases will be presented. The first case is INPS v WS (C-302/19), dealing with the Italian legislation that excludes Single Permit holders from receiving family benefits for their family members residing in a third country. In the second report, two cases rendered on the same day by the Grand Chamber of the Court are discussed. In D.J. v Radiotelevizija Slovenija (C-344/19) and RJ v Stadt Offenbach am Main (C-580/19), the Court clarified the circumstances under which periods of stand-by time could be considered as ‘working time’ or, alternatively, ‘rest periods’ under Directive 2003/88. XI v Caisse pour l’avenir des enfants (C-129/20) is the third case reported. It concerns an interpretation of the Framework Agreement on parental leave in the light of the Luxembourg legislation, which requires parents to be employed at the time of their child’s birth to benefit from parental leave. Finally, the case report ends with VL v Szpital Kliniczny im. dra J. Babińskiego Samodzielny Publiczny Zakład Opieki Zdrowotnej w Krakowie (C-16/19), a case of discrimination on grounds of disability.

Abstract Low-grade B-cell lymphoma of mucosa-associated lymphoid tissue involving the kidney is rare. We report a series of 3 cases. The first case occurred in an 83-year-old woman who presented with back pain. The second case was a 53-year-old man with a history of sarcoidosis who was found, in the course of evaluation of sarcoidosis, to have a right renal mass. The third case occurred in a 72-year-old man who had a history of periorbital mucosa–associated lymphoid tissue lymphoma and had been treated with surgery and radiation 1 year prior to this presentation. Histologically, all 3 patients showed infiltrate of uniform small-to-medium–sized lymphocytes with irregular nuclear contours and abundant cytoplasm resembling centrocytes or monocytoid lymphoid cells. The first patient received chemotherapy without complications. The second patient underwent a partial nephrectomy and was asymptomatic at the subsequent follow-up. The third patient developed a pulmonary embolism following nephrectomy, and further follow-up is not available.

Abstract Background Femoral neck fractures in adults younger than age 50 years are uncommon and often the result of high energy trauma. They account for only 2-3% of all femoral neck fractures. Femoral neck fractures are associated with aging and osteoporosis and can occur after relatively trivial trauma in elderly patients. femoral neck fractures are associated with higher incidences of femoral head osteonecrosis and nonunion. Fixation options include cannulated screws, non parallel cannulated screws, medial augmentation plate, and fixed angle femoral neck fixation implants. A systematic review of literature done to evaluate which technique is better. Methods After literature search thirteen articles were found and were reviewed to evaluate final outcome of fixation of neck femur fractures by cannulated screws, non parallel cannulated screws, medial augmentation plate, and fixed angle femoral neck fixation implants. Results After evaluation of all studies the incidence of nonunion, osteonecrosis of femoral head, implant failure & revesion surgery is lower in comparing Targon plate with multiple cannulated screws while we need further studies for application of non parallel screws and medial plate. Conclusion Targon plate recorded low incidence of complications in the final outcome in comparison with multiple cannulated screw while we need further studies for application of Non parallel screws and medial plate.

AbstractThree patients aged five years, five years four months and 14 years with obstruction of the systemic venous baffle following the Mustard operation were treated with balloon dilation and implantation ofstents. Balloon dilation of the baffle obstruction was performed initially in the first two cases. In the third case, the obstruction was complete and was punctured with atranseptal needle via a 6 French transeptal sheath followed by a balloon dilation. in all three patients, a Palmaz stent (Johnson & Johnson, Summerville, New Jersey, USA) was loaded onto the balloon catheter and delivered into the stenotic area. There was complete relief of obstruction in allcases. The first case developed supraventricular tachycardia at the time ofcatheterization, the morning following implantation of the stent and thentwo weeks after that. There were no complications with catheterization and noshort-term side effects in the other cases. These cases illustrate the use of endovascular stents in the treatment of baffle obstruction.

Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysaccharides triggers the activation of Toll-like receptors which stimulate the process of hepatocarcinogenesis. Prebiotics, nondigestible oligosaccharides, have a pivotal role to play when it comes to inducing an antitumor effect. A healthy gut flora balance is imperative to downregulation of inflammatory cytokines and reducing lipopolysaccharides induced endotoxemia, thus inducing the antitumor effect.
