Morbidity and mortality associated with ventral skull base surgery: analysis of the National Surgical Quality Improvement Program.

BACKGROUND: Ventral skull base (VSB) surgery has associated morbidity and mortality that is poorly defined. In this study we aim to identify factors associated with adverse events in VSB surgery. METHODS: We queried the database of the American College of Surgeons National Surgical Quality Improvement Program for cases of VSB surgery during the period 2005-2014. Patients with complications, readmissions, reoperations, or mortality were compared to those without adverse events. RESULTS: Nine hundred patients were included; 253 (28.1%) had complications, underwent reoperation, were readmitted, or died. These patients were older (42.6% vs 32.8, p = 0.032) and had higher rates of congestive heart failure (CHF) (3.2% vs 0.2%, p < 0.0001), disseminated cancer (8.3% vs 4.6%, p = 0.032), and preoperative sepsis (8.7% vs 2.2%, p < 0.0001). Other comorbidities included long-term steroid use (13.4% vs 9.0%, p = 0.046) and higher rates of preoperative transfusion (2.4% vs 0%, p < 0.0001). The most common complication was bleeding (13.7%). Preoperative systemic sepsis (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.0-6.6) and lower hematocrit (OR, 2.1; 95% CI, 1.4-3.4) were more likely to be associated with a complication. Those with disseminated cancer (OR, 12.0; 95% CI, 2.9-50.5) were more likely to experience 30-day mortality. Black patients had lower rates of reoperation (OR, 0.3; 95% CI, 0.1-0.8), whereas patients with CHF (OR, 12.6; 95% CI, 1.7-94.4) and hypertension (OR, 2.1; 95% CI, 1.1-4.0) had higher rates of reoperation. Predictors of extended length of stay were Hispanic ethnicity (OR, 2.2; 95% CI, 1.2-4.1) and lower hematocrit (OR, 2.3; 95% CI, 1.5-3.6). CONCLUSION: VSB surgery can involve significant morbidity and mortality, and thus identifying risk factors allows for better prognostication and delivery of care in these patients.

Successfully removed uterine angioleiomyoma by robot-assisted laparoscopic myomectomy.

Angioleiomyoma is a rare type of leiomyoma variant and there are a few cases reported to date. Herein, we present a case of angioleiomyoma in a 36-year-old woman with lower abdominal pain, initially diagnosed by degenerated uterine leiomyoma. The transvaginal ultrasonogram showed an ovoid-shaped heterogeneously hyperechoic lesion in left cornual site of uterus and pelvic magnetic resonance image showed an about 5.1 cm sized heterogenous T2 intermediate high mass with poor enhancement. The patient underwent a robot-assisted laparoscopic myomectomy, and final histopathologic diagnosis revealed uterine angioleiomyoma. This case is the first case of angioleiomyoma resected by robotic surgery. The patient is on follow up for over 1 year and shows no evidence of recurrence until now.

Comparison of the toxicity of aqueous and ethanol fractions of Angelica keiskei leaf using the eye irritancy test.

To determine whether aqueous and ethanol fractions of the Angelica keiskei leaf exert toxicity when used for cosmetic purposes, we performed the acute eye irritancy test. Animals were treated with sample fractions (100 mg/dose) according to standard procedure guidelines. No significant changes or damage was detected in the fraction-treated groups in terms of ocular lesions in the cornea, the size of the cornea with turbidity, swelling of the eyelid and emission discharge. However, sodium dioctyl sulfosuccinate, a positive control, induced severe toxic symptoms. Thus, aqueous and ethanol fractions of Angelica keiskei do not appear to induce acute toxicity in the eye lens, as assessed from anatomical and pathological observations in the rabbit eye. Our results collectively suggest that aqueous and ethanol fractions show promise as cosmetic ingredients that do not cause eye toxicity.
