Objectives/hypothesis: To evaluate the demographics, clinical features, management, and prognostic indicators of tracheoesophageal puncture complications in patients undergoing placement of voice prosthesis following cancer treatment.
Study Design: Retrospective analysis.
Methods: A retrospective analysis was conducted of cases from a tertiary referral center diagnosed between 1996 and 2015. Multivariate logistic regression was used to determine factors associated with tracheoesophageal puncture (TEP) and voice prostheses-complication-free survival (TEP/VP-CFS).
Results: One hundred fourteen cases were identified. Most patients were males (92.9%) with pT3 (26.8%) or pT4 (58.1%) N+ (53.6%) tumors. All patients received laryngectomy as the primary treatment, with 75% of patients receiving adjuvant radiation therapy or chemoradiotherapy. Complications with TEP were common (65.2%). The most frequent problem was salivary leakage (50.0%), which at the same time was the most common reason for changing the prosthesis. On univariate regression analysis, prosthesis placement time after adjuvant radiotherapy (hazard ratio [HR]: 4.17, 95% confidence interval [CI]: 2-8.69), secondary prosthesis placement after primary surgery (HR: 3.97, 95% CI: 1.99-7.9), and laryngectomy with flap reconstruction (HR: 1.96, 95% CI: 0.99-3.89) were significant prognosticators for complications. Multivariate regression analysis revealed secondary prosthesis placement after adjuvant radiotherapy (HR: 3.66, 95% CI: 1.39-9.68) or after primary surgery (HR: 2.57, 95% CI: 0.92-7.2) to be the strongest predictors of reduced TEP/VP-CFS.
Conclusions: Secondary prosthesis placement after primary surgery, placement after previous irradiation, and laryngectomy with flap reconstruction are predictors of poor TEP/VP-CFS. Planned adjuvant radiotherapy is not a contraindication for TEP with prosthetic placement, but it is very important to place the prosthesis during the primary surgery or at least before scheduled radiotherapy.

Atlantoaxial dislocation (AAD) is a serious condition in which the first two cervical vertebrae lose their anatomical position and stability. This may lead to neurological complications, including death. The treatment of AAD remains controversial, and posterior instrumentation with pedicle screw placement is one of the commonly used methods.

The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant.

Cannulated screws have significant advantages, including ease of insertion and increased accuracy, during fracture fixation. Unraveling of screw threads is an uncommon complication related to cannulated screws. This single-institution case series aims to highlight four cases of unraveling of cannulated screw threads during the fixation of medial epicondyle humerus fractures in adolescents.

Background: When designing removable partial dentures, maximizing the effectiveness of support and bracing is necessary to minimize denture movement. Therefore, it is essential to emphasize the importance of providing patients with appropriate, safe, and secure removable partial dentures and have clinicians rerecognize the concept and importance of support and bracing. This study aimed to present extension-base removable partial dentures through six specific clinical case series and describe the effect of support and bracing action on denture design, which is essential for denture movement minimization.

A patient in his early adolescence, who was treated for T5-T6 tubercular spondylodiscitis with an un-instrumented decompression, presented at 36 months post-index surgery, for post-laminectomy instability and kyphosis, after completing his requisite antitubercular treatment. He underwent thoracic posterior instrumented kyphosis correction and anterior reconstruction, with a T5-T6 partial corpectomy and corpectomy spacer placement, through a posterior midline incision. On the second postoperative day, he started complaining of pain on the left side of his chest, abdomen and left shoulder.
