OBJECTIVE Information extraction and classification of clinical data are current challenges in natural language processing. This paper presents a cascaded method to deal with three different extractions and classifications in clinical data: concept annotation, assertion classification and relation classification. MATERIALS AND METHODS A pipeline system(More)
OBJECTIVE To report a novel technique for cervical reconstruction in a patient with congenital agenesis of the cervix. DESIGN Case report. SETTING University-based tertiary care hospital. PATIENT(S) A woman with congenital absence of the cervix, functional vagina, and adenomyosis uteri. INTERVENTION(S) Laparoscopic-assisted creation of an(More)
BACKGROUND AND OBJECTIVE A high percentage of bronchoscopically extracted foreign bodies in Ho Chi Minh City were pits of the sapote fruit, a finding previously unreported. This paper presents a review of foreign body extractions, which identifies the substances found, documents the diagnostic pathway and draws attention to the specific aspiration risk of(More)
Fibrin sealant (FS) has been used successfully as an effective adhesive and hemostatic agent in a variety of surgical procedures. At the University of Virginia, autologous fibrin sealant is used to reduce the potential accumulation of serous fluid after axillary dissection in patients undergoing modified radical mastectomy (MRM) for carcinoma of the breast.(More)
Seroma formation following mastectomy and axillary dissection remains a common and significant problem contributing to patient morbidity and health-care costs. Previous data have suggested that fibrin sealant (FS), a biological adhesive, is capable of controlling lymphatic leakage and assisting with skin graft adhesion. In this study, the use of an(More)
OBJECTIVE Vascularized groin lymph node flaps have been successfully transferred to the wrist to treat postmastecomy upper limb lymphedema. This study investigated the anatomy, mechanism and outcome of a novel vascularized submental lymph node (VSLN) flap transfer for the treatment of lower limb lymphedema. METHODS Bilateral regional submental flaps were(More)
BACKGROUND Evaluation of skill acquisition in microsurgery has traditionally relied on subjective opinions of senior faculty, but is shifting toward early competency-based training using validated models. No objective measures of dexterity, economy of movement, and ability exist. The authors propose a novel video instrument motion analysis scoring system to(More)
The University of Virginia Health System inpatient satisfaction survey identified noise as the most important irritant to surgical inpatients. Analysis of the level and pattern of noise on patient floors and intensive care units was done with baseline measurements followed by then two separate interventions: 1) education of nursing and physician staff 2)(More)
OBJECTIVES/HYPOTHESIS This study was designed to investigate the anatomical features and applications of the ulnar forearm flap in head and neck reconstructive surgery. STUDY DESIGN A prospective study was designed to include 50 ulnar forearm free flap transplants in 50 patients. Patient defects requiring reconstructive surgery involved the buccal mucosa,(More)
BACKGROUND Successful breast reconstruction includes the creation of a natural breast mound in addition to achieving maximal symmetry of both breasts. This study investigated the patients' outcome and satisfaction of simultaneous contralateral balancing reduction/mastopexy with unilateral breast reconstruction using free abdominal flaps.
