BACKGROUND Bronchoscopic lung volume reduction using one-way endobronchial valves (EBVs) has been proven to be effective in patients with severe emphysema. However, the selection of patients without collateral ventilation prior to treatment is critical for procedural success. Collateral ventilation can be assessed directly with the Chartis system or indirectly using computed tomography (CT) fis...

We study land subsidence processes and the associated ground fissuring, affecting an active graben filled by thick unconsolidated deposits by means of InSAR techniques and fieldwork. On 21 September 2012, Ciudad Guzmán (Jalisco, Mexico) was struck by ground fissures of about 1.5 km of length, causing the deformation of the roads and the propagation of fissures in adjacent buildings. The field s...

A pulmonary fissure is a boundary between the lobes in the lungs. Its segmentation is of clinical interest as it facilitates the assessment of lung disease on a lobar level. This paper describes a new approach for segmenting the major fissures in both lungs on thin-section computed tomography (CT). An image transformation called "ridge map" is proposed for enhancing the appearance of fissures o...

PURPOSE To describe the spectrum of adnexal and ophthalmologic features in spina bifida. METHODS A retrospective review of the medical records of 73 patients was conducted. Data concerning ocular motility, palpebral fissure orientation, presence and axis of astigmatism, visual acuity, amblyopia, and stereopsis were analyzed. RESULTS Forty-three (59%) of the 73 patients had strabismus: 28 (6...

OBJECTIVE To evaluate two different approaches used to perform fused fissures in lobectomies in terms of persistent air leak (PAL) and their impact on length of hospital stay. METHODS One hundred and nineteen patients underwent lobectomy or bilobectomy in our unit. We focused on patients with fused fissures (63 patients), all of whom were selected intraoperatively based on predefined criteria...

Although ovarian cancer remains a leading cause of gynecologic cancer death, targeted therapies are improving patient outcomes. Anal fissures are a side effect of targeted therapies that can disrupt or stop treatment regimens. Diagnosis and management of anal fissures by advanced practice nurses are crucial for maintaining the quality of life of patients with ovarian cancer.
