Chest Wall Reconstruction Utilizing Ovine-derived Reinforced Tissue Matrix.

BACKGROUND: Chest wall reconstruction can be a challenge. The perfect material does not exist to restore chest wall stability. Synthetic materials have been the mainstay for reconstruction. Biological material use has increased. Recently, we initiated the use of a biosynthetic material for chest wall reconstruction that is composed of ovine-derived extracellular tissue matrix and monofilament polypropylene suture. METHODS: We respectively reviewed all patients who underwent chest wall reconstruction with a biosynthetic material from January 2020 to June 2021. RESULTS: Twenty-five patients underwent chest wall reconstruction. Median age was 35 years (range, 18 to 68); 64% were men. Indication for reconstruction was tumor resection in 10, chest wall defect after pectus repair in 7, radiation necrosis in 5, chest wall infection in 2, and lung herniation in 1. Infection was present in 28%. Median chest wall defect was 7 × 10 cm (range, 3.5 to 22.5 cm). Bioabsorbable bars were used in combination with the biosynthetic material patch in 15 patients (60%) and biosynthetic material alone in 10; 5 patients underwent myocutaneous advancement flaps. There were no operative deaths. Postoperative complications occurred in 6 patients (24%). Median hospital stay was 5 days (range, 3 to 14). Late complications occurred in 4 patients (16%). No patient had paradoxical motion, chest wall instability, or required biosynthetic material removal at a median follow-up of 12 months (range, 1 to 18). CONCLUSIONS: This novel biosynthetic material combines the benefits of biologic material and polymer reinforcement to provide a more natural chest wall reconstruction compared with mesh products made of synthetic material alone. Early results are promising in this first series in the literature.

Bilateral Lymphatic Spread of Metastatic Basal Cell Carcinoma.

Herein, we report a case of a patient with an abnormal skin lesion that remained unchecked by medical professionals for approximately 20 years. Upon physical examination in the emergency department for a fractured hip, an infiltrative mass was incidentally discovered. The neoplasm was noted to have progressed from an eraser-sized mass to a 3.5-cm invasive lesion. Initial surgical intervention was believed to have been successful in removal, as margins were clear with the exception of 1 indeterminate segment. However, subsequent 1-year follow-up revealed recurrence of the disease with bilateral axillary node and deep muscle involvement. This prompted a more extensive surgical approach complemented with radiation therapy. The patient had remained disease-free for a year.

Verrucous carcinoma of the paranasal sinuses: a case report.

Verrucous carcinoma is a low-grade variant of squamous cell carcinoma reported to occur in all anatomic sites in the head and neck region, most commonly the oral cavity. The tumor grows locally invasive but is histologically benign and metastasizes rarely. To date, 22 cases of verrucous carcinoma involving the nasal cavity and/or the paranasal sinuses have been reported. We present a case of verrucous carcinoma involving the paranasal sinuses, nasal cavity, cranium, and orbit. This case highlights the difficulty of pathologic diagnosis and management options for a rare neoplastic lesion.

Pediatric airway consultation survey in a tertiary care children's hospital: an interobserver analysis.

We conducted a prospective analysis to independently observe the initial opinion of: (1) consulting pediatric residents (postgraduate year 2 [PGY-2]), (2) corresponding consulting attending physicians (general pediatric or pediatric emergency medicine), and (3) consulting otolaryngology PGY-2 residents when assessing patients for "noisy breathing." Each was asked to define the type of noisy breathing present and to formulate a diagnosis based on a limited set of choices. The final diagnosis was determined by a single attending pediatric otolaryngologist (S.E.S.) at the completion of the diagnostic workup. The accuracy for characterization of breath sounds for the pediatric residents, attending pediatricians, and otolaryngology residents were 26.1%, 23.5%, and 98.6%, respectively. The positive predictive values for the determination of diagnosis were 71.6%, 69.4%, and 76.6%, respectively. These findings indicate that pediatric residents and attending pediatricians may be deficient in their ability to characterize the breath sounds commonly seen in patients with noisy breathing. Further education of pediatricians may lead to a more accurate diagnostic evaluation of a child with noisy breathing.

The coexistence of anaplastic and papillary carcinomas of the thyroid: a case presentation and literature review.

Papillary carcinomas of the thyroid are the most common malignant growth affecting the thyroid, currently representing 60-65 per cent of malignant thyroid neoplasm. Although the etiology of this neoplasm is unknown, they are thought to be related to neck irradiation, adenoma transformation, and Hashimoto thyroiditis. Papillary carcinomas are usually purely papillary but occasionally have areas of histologically different neoplasm, most commonly follicular. Overall, these carcinomas represent an indolent group of neoplasm and have an excellent prognosis. The occurrence of an anaplastic area in a papillary carcinoma represents the dedifferentiation of the primary neoplasm. This is an extremely rare occurrence and is considered to have negative prognostic significance. The purpose of this presentation is to discuss an unusual clinical case of a coexisting anaplastic and papillary carcinoma of the thyroid, diagnosed by fine needle aspiration (FNA) analysis presenting in a 67-year-old African-American woman. Evaluation and treatment will be discussed.
