Evidence-Based Antibiotic Prophylaxis in Clean Hand Surgeries: An Educational Intervention to Decrease Use.

Purpose: Evidence for the use of prophylactic antibiotics in clean hand surgery is limited, yet surgeons continue to administer antibiotics to prevent postoperative infections. We sought to assess the effect of a program directed at reducing the use of antibiotic prophylaxis in carpal tunnel release surgery and elicit reasons for continued use.

Methods: A surgeon leader implemented a program between September 1, 2018 and September 30, 2019 to reduce antibiotic prophylaxis in clean hand surgeries in a hospital system of 10 medical centers.

Multiple myxoid cellular neurothekeomas in a patient with systemic lupus erythematosus.

Cellular neurothekeoma is a cutaneous tumor with a distinctive histopathologic appearance characterized by a dermal-based multinodular proliferation of epithelioid to spindled cells. Although the tumor may show varying amounts of myxoid stroma, extensive myxoid change is uncommon. The tumor typically presents as a solitary nodule with a predilection for the head and neck and upper limbs; examples of multiple cellular neurothekeomas are decidedly rare.

Ossifying Plexiform Tumor: A Case Report.

Ossifying plexiform tumor is an exceedingly rare cutaneous neoplasm with distinctive histologic features. The typical microscopic appearance is that of a well-circumscribed dermal lesion composed of spindled and epithelioid cells in a myxoid appearing matrix with a plexiform architecture associated with areas of ossification. The present report details the clinicopathologic features of an ossifying plexiform tumor involving the lower extremity of a 69-year-old man.

Tongue Schwannoma: A Clinicopathologic Study of 19 Cases.

Schwannomas commonly occur in the head and neck but infrequently involve the oral cavity and rarely affect the tongue. The clinical and pathologic features of 19 cases of schwannoma arising in the tongue were analyzed. There were 13 males and 6 females ranging in age from 12 to 82 years (mean 34 years; median 29 years).

Sporadic Neurofibroma of the Tongue Unassociated with Neurofibromatosis Type I: A Clinicopathologic Study of Ten Cases.

Neurofibromas rarely occur within the oral cavity and infrequently involve the tongue. The majority of lingual neurofibromas arise in patients affected by neurofibromatosis type 1 (NF1). Neurofibromas of the tongue unassociated with this disorder are exceedingly uncommon.

Thyroid Gland Solitary Fibrous Tumor: Report of 3 Cases and a Comprehensive Review of the Literature.

Solitary fibrous tumors of the thyroid gland are exceptionally rare. In order to further characterize the clinical and pathologic features of solitary fibrous tumor arising at this anatomic site, three cases of thyroid gland solitary fibrous tumor were analyzed in conjunction with 35 cases compiled from the English literature. Thyroid gland solitary fibrous tumors showed an equal sex distribution with a mean age at presentation of 54.

A new technique in complex chest wall reconstruction: Open reduction and internal fixation.

Background: Reconstruction of complex chest wall deformities is a surgical challenge. A new technique can improve long-term outcomes and result in high patient satisfaction.

Methods: A multicenter study was conducted on pediatric patients undergoing complex chest wall reconstruction between September 2015 and January 2018.

Cutaneous Smooth Muscle Tumors: A Review.

Smooth muscle tumors occur infrequently in the skin. They consist of a diverse group of lesions representing hamartomas as well as benign and malignant neoplasms. They may arise from arrector pili muscle, specialized smooth muscle of the genitalia, or vascular smooth muscle.

Sinonasal Tract Solitary Fibrous Tumor: A Clinicopathologic Study of Six Cases with a Comprehensive Review of the Literature.

Solitary fibrous tumors (SFTs) are well recognized in the head and neck region, but rarely arise in the sinonasal tract (SNT). Six primary SNT SFTs were identified in the files of Southern California Permanente Medical Group between 2006 and 2017. The patients included five males and one female ranging in age from 33 to 72 years (mean 52 years), most of whom presented clinically with nasal obstruction.

Thyroglossal Duct Cyst Carcinomas in Pediatric Patients: Report of Two Cases with a Comprehensive Literature Review.

Thyroglossal duct cyst (TGDC) carcinomas are rarely encountered in the pediatric population. The clinical behavior of these tumors in the pediatric setting is unclear and management is not well defined. Two cases of pediatric thyroglossal duct cyst carcinoma were identified in a review of all thyroglossal duct cysts diagnosed over a ten year period.

A Clinicopathologic Series of 685 Thyroglossal Duct Remnant Cysts.

The clinical features of thyroglossal duct remnant cysts (TGDC) have been well described, however the histopathologic aspects of these lesions have not been addressed in a detailed manner. In particular, there has been no large community practice based series evaluating TGDC histologically compared with management outcomes. A retrospective review of all TGDC diagnosed between 2005 and 2015 was performed.

Thyroglossal Duct Cyst Carcinomas: A Clinicopathologic Series of 22 Cases with Staging Recommendations.

Carcinomas arising from thyroglossal duct remnant cysts (TGDCs) are rare, without well-defined management and staging criteria. All TGDCs (n = 685) diagnosed between 2005 and 2015 were retrospectively reviewed, with 22 carcinomas identified (3.2 % incidence).

Spindle cell lipoma of the tongue: a clinicopathologic study of 8 cases and review of the literature.

Spindle cell lipoma is a histologically distinct variant of lipoma characteristically arising in the subcutis of the posterior neck, upper back, or shoulder. Spindle cell lipomas infrequently occur within the oral cavity and, in particular, rarely involve the tongue. The clinical and pathologic features of eight cases of spindle cell lipoma affecting the tongue were analyzed.

Oncocytic lipoadenoma of the salivary gland: a clinicopathologic analysis of 7 cases and review of the literature.

Oncocytic lipoadenoma is an exceedingly uncommon neoplasm of the salivary gland composed of oncocytic epithelium and adipose tissue. Retrospective. Seven cases of oncocytic lipoadenoma were analyzed in order to further characterize the clinical and pathologic features of this rare tumor.
