#1
Roa Alammari, Renee Thibodeau, Oz Harmanli
BACKGROUND: Cervical ectopic pregnancy can lead to catastrophic hemorrhage, and may be managed conservatively with intra-amniotic methotrexate (MTX), systemic MTX, or both; surgical evacuation with or without balloon tamponade; and uterine artery embolization. However, some patients require hysterectomy, which has traditionally been performed abdominally. CASE: A 39-year-old parous woman was diagnosed with cervical ectopic pregnancy at an estimated 7 1/7 weeks of gestation...

Animal models provide a useful platform for developing and testing new drugs to treat liver fibrosis. Accordingly, we developed a novel automated system to evaluate liver fibrosis in rodent models. This system uses second-harmonic generation (SHG)/two-photon excited fluorescence (TPEF) microscopy to assess a total of four mouse and rat models, using chemical treatment with either thioacetamide (TAA) or carbon tetrachloride (CCl4), and a surgical method, bile duct ligation (BDL). The results obtained by the new technique were compared with that using Ishak fibrosis scores and two currently used quantitative methods for determining liver fibrosis: the collagen proportionate area (CPA) and measurement of hydroxyproline (HYP) content...

We describe a novel robotically assisted minimally invasive surgical technique for repair of partial anomalous pulmonary vein connection (PAPVC). Partial anomalous pulmonary vein connection is a rare congenital anomaly that consists in drainage of one or more pulmonary veins into the systemic venous system. Traditionally, large thoracotomy incision and sometimes establishment of cardiopulmonary bypass are needed to redirect the abnormal pulmonary vein to the left-sided reservoir. We describe a robotically assisted, minimally invasive, off-pump technique for the treatment of the left PAPVC in a 57-year-old patient with signs of progressive right ventricular dilatation...

Chronic tricuspid valve regurgitation is usually associated with left-sided heart disease or pulmonary hypertension. Although severe tricuspid valve regurgitation carries a poor prognosis, isolated surgery is rarely performed due to high in-hospital mortality and an unclear impact on long term survival. The lack of adequate surgical treatment has resulted in a large population of patients with an unmet clinical need. Areas Covered: Transcatheter therapies have revolutionized the management of high risk patients with left-sided valvular disease, and have sparked interest in translating minimally invasive therapies to the tricuspid valve...
