Chronic Sphenoiditis With Deep Neck Space Extension: Case Report With Review of the Literature and Postulated Mechanisms for Extracranial Extension.

Isolated primary sphenoid sinusitis is a rare occurrence, estimated to make up less than 3% of sinus infections. The posterior anatomic location of the sphenoid makes treatment challenging when it becomes infected. Complications involving intracranial extension to surrounding structures often result in cranial nerve deficits due to their proximity. A single case of chronic sphenoiditis with direct extracranial extension into the prevertebral space is reported with a discussion on clinical presentation, diagnosis, and management. A 46-year-old female patient with diffuse headaches radiating into the neck and throat was evaluated in the office. Computed tomography demonstrated sphenoiditis with direct extension into the prevertebral space. Imaging revealed a purported route of direct extension through the clinoid and directly into the clivus to form an abscess in the longus colli muscle. The patient underwent endoscopic surgical management including drainage of the prevertebral abscess and has since made a full recovery. This is the first reported case of direct extension of sphenoiditis into the prevertebral space. The findings highlight the importance of aggressive treatment of chronic sphenoid infections to prevent detrimental complications. Computed tomography imaging proved an advantageous imaging modality to demonstrate bony erosion and sinus tracts from the skull base to the deep neck space.

Readmission After Emergency General Surgery: NSQIP Review of Risk, Cause and Ideal Follow-Up.

BACKGROUND: The Emergency General Surgery (EGS) population is particularly at high risk for readmission. Currently, no system exists to predict which EGS patients are most at risk. We hypothesized that a subset of EGS patients could be identified with increased 30-day unplanned readmission. We also hypothesized that a majority of readmissions occur sooner than the conventional 2-week follow-up period. METHODS: National Surgical Quality Improvement Program (NSQIP) nonelective general surgery patients were analyzed. Multivariable logistic regression identified factors with increased odds of unplanned readmission. AAST EGS Diagnosis Categories were used to categorize postop ICD-9 codes, and the top 10 CPT codes in each group were analyzed. Readmission rate, the reason for unplanned readmission, and time to readmission were analyzed. RESULTS: A total of 383,726 patients were identified with a readmission rate of 8.1% within 30 d of their primary procedure. The top 50 CPT codes accounted for 84% of EGS readmissions. Increased readmission risk was demonstrated for underweight patients (OR = 1.15, P < 0.05). High-risk hospital characteristics were LOS >2 d, any inpatient pulmonary complications, and discharge to any facility or rehab (all P < 0.05). Surgical site infections cause nearly 25% of readmissions. Intestinal procedures are most frequently readmitted (22% of EGS readmissions), with colorectal procedures having the higher odds of readmission. Most readmissions occur <10 d after discharge. CONCLUSIONS: A high-risk subpopulation exists within EGS, and most readmissions occur sooner than a typical 2-week follow-up. Early interventions for high-risk EGS subpopulations may allow for early intervention and reduction of unnecessary healthcare utilization.

Eccentric, mature osseous cap: A distinct imaging feature of sinonasal osteoblastoma.

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature. RESULTS: Two cases of sinonasal osteoblastoma were managed by definitive surgical resection. Both tumors on preoperative computed tomography demonstrated an expansile, heterogeneous fibro-osseous lesion with an eccentric, mature osseous cap. The dense osseous cap seen on imaging corresponded to a rim of mature bone on histopathology. A review of existing literature revealed the presence of this imaging sign in all reported cases. CONCLUSION: Sinonasal osteoblastoma is an extremely rare entity with undefined imaging characteristics to guide preoperative decision-making. Here we reported, to our knowledge, the first description of a characteristic imaging sign of an eccentric, mature osseous cap, which corresponded histologically to a single peripheral layer rim of osteoblasts, a unique trait of osteoblastoma.

Reap What You Sow: Which Rural Surgery Training Programs Currently Exist and Do Medical Students Know of Their Existence?

BACKGROUND: There exists an acute need to recruit and train general surgeons for rural communities. To assist medical students interested in rural surgery, the American College of Surgeons (ACS) website lists general surgery residencies, which are tailored to train the rural surgeon by providing exposure to endoscopy, gynecology, urology, orthopedics, and otolaryngology. Another available reference is the American Medical Association Fellowship and Residency Electronic Database (FREIDA). FREIDA allows programs to indicate availability of a rural training scheme. This is an effort to identify programs which demonstrate a commitment to training rural surgeons and evaluate accessibility of this information to medical students. METHODS: Each ACGME general surgery residency program in the United States and Canada received an electronic survey. They were queried on commitment to training rural surgeons and their ability to provide 3 to 12 months of subspecialty training. RESULTS: Of the 261 programs surveyed, 52 (19.9%) responses were obtained; 11 had established rural tracks and 15 were willing to customize a program. We identified 14 additional rural training programs not identified by either the ACS website or FREIDA. In total, 44 programs identified by ACS, FREIDA, and our survey indicate they can accommodate the rural surgical resident. CONCLUSIONS: For a medical student interested in rural surgery, several obstacles must be overcome to find the appropriate residency program. A complete and updated list of established tracks or customizable training schemes does not exist. Review of the ACS website and FREIDA online in addition to our survey has identified 44 of 261 (16.9%) ACGME accredited programs either with an existing rural surgical track or willing to customize their program accommodate a resident. To facilitate the recruitment of medical students into rural surgery, we support the maintenance of a complete and routinely updated list that identifies available training programs.
