Axillary Nodal Burden in Breast Cancer Patients With Pre-operative Fine Needle Aspiration-proven Positive Lymph Nodes Compared to Those With Positive…
2019
BACKGROUND/AIM: Recent years have seen a considerable shift to a more conservative management of the axilla in patients with positive axillary sentinel lymph nodes. The aim of this study was to determine whether some breast cancer patients with a preoperative ultrasound-guided needle aspiration biopsy proven positive node could potentially be spared an axillary lymph node dissection according to the ACOSOG Z0011 trial criteria. PATIENTS AND METHODS: A retrospective review was performed involving 623 breast cancer patients who underwent axillary lymph node dissection after either ultrasound-guided needle aspiration biopsy proven positive node or sentinel lymph node biopsy. RESULTS: Patients …
Pre- and intraoperative methods of controlling cerebral circulation in giant aneurysm surgery.
1995
The surgical treatment of giant aneurysms usually requires temporary clipping of the aneurysmatic vessel. In planning the surgical approach and in applying temporary clips, the surgeon must consider collateral circulations. The functional integrity of the collateral vessels frequently decides the patient's outcome. In 8 patients with internal carotid artery giant aneurysm, measurements of blood flow velocities in the ipsilateral middle cerebral artery were performed preoperatively with transcranial Doppler ultrasound (TCD) during manual occlusion of the carotid artery at the neck. Three different perfusion patterns were established, and each collateral capacity was rated as insufficient, te…
Traumatic damage to the cartilage influences outcome of anatomically reduced acetabular fractures: A medium-term retrospective analysis
2011
We reviewed 77 patients with an acetabular fracture, treated operatively through a non-extensile approach after an average time of 45 months. The ilioinguinal approach was chosen in 41, the Kocher-Langenbeck approach in 36 patients. Following the Letournel classification, the most frequent lesions were posterior wall (26%), two-column (22.1%) and anterior column (14.3%) fractures. Subchondral impaction, intra-articular fracture fragments and fracture comminution, called modifiers, could be identified in the preoperative CT-data of 38 patients (49.4%). Patients were operated after an average of 4 days. Average hospital stay was 19 days. Sciatic nerve and peroneal nerve palsy were registered …
Survival After Transplantation of Corneas From a Rabies-Infected Donor
2011
To examine the tissue samples of 2 corneal recipients from a rabies-infected donor for the presence of rabies to explain their survival.Interventional case series with a review of the literature. The explanted corneal donor buttons were examined via nested reverse transcriptase polymerase chain reaction. The patients were followed up ophthalmologically and neurologically. Antirabies antibodies were measured in blood samples, and skin biopsies were examined by direct fluorescent antibody staining.Two patients received corneas from the same multiorgan donor. Six weeks after transplantation, 3 of the donor's organ recipients became symptomatic and rabies virus was confirmed in tissue from the …
Spontaneous Resolution of Delayed Suprachoroidal Hemorrhage in the Single Eye Following Needling in Congenital Glaucoma
2017
Suprachoroidal hemorrhage (SCH) is a rare, but potentially vision-threatening event with poor long-term visual prognosis. At present, there is disagreement whether surgical intervention or conservative treatment is superior in the management. We report on a case of spontaneous resolution of severe SCH after needling procedure in the only eye of a young patient with congenital glaucoma.A 43-year-old woman with congenital glaucoma was scheduled for bleb needling in her only eye. Preoperative best-corrected visual acuity was 20/40 and intraocular pressure 20 mm Hg. On the third postoperative day, she developed a massive delayed SCH with appositional (kissing) choroidal bullae and visual acuity…
Delayed Coloanal Anastomosis for rectovaginal fistula after colorectal resection for deep endometriosis
2016
The deep infiltrating endometriosis, defined as a subperitoneal infiltration of endometrial implants of ≥ 5 mm involving not only the colorectal tract but also rectovaginal septum, vagina and bladder often requires a challenging surgery. Endometriosis nodes of the rectovaginal septum, if symptomatic, need a resection of the involved colorectal tract with colorectal or coloanal anastomosis. Unfortunately in these cases is not uncommon the possibility of a postoperative rectovaginal fistula (RVF), caused by the weakness of the septum that must be skeletonized to completely remove the endometriosis nodes. Here we present a case of anastomotic leakage with high RVF after colorectal resection an…
Effect of Simulated IOL Tilt and Decentration on Spherical Aberration After Hyperopic LASIK for Different Intraocular Lenses
2011
PURPOSE: To evaluate visual quality differences among intraocular lenses (IOLs) in patients with previous hyperopic laser ablations and to assess the impact of decentration and tilt of IOLs on visual quality. METHODS: An adaptive optics visual simulator was used to simulate the wavefront aberration pattern of one aberration-correcting IOL (AcrySof IQ SN60WF, Alcon Laboratories Inc) and two spherical IOLs with different amounts of positive spherical aberration (Akreos Adapt [Bausch & Lomb] and Triplato [AJL Ophthalmic]) in five situations—centered, 0.2 mm and 0.4 mm of decentration, and 2° and 4° of tilt—in two groups: simulated low hyperopic laser corneal ablation (low hyperopia group)…
Empowering counseling--a case study: nurse-patient encounter in a hospital
2001
This study illustrates practices that a nurse uses in order to empower patients. The emphasis is on speech formulae that encourage patients to discuss their concerns and to solicit information about impending surgery. The study is a part of a larger research project and a single case was selected for presentation in this article because it differed from the rest of the data by manifesting empowering practice. A videotaped nurse-patient health counseling session was conducted in a hospital and transcribed verbatim. The investigator interviewed the nurse and the patient after the conversation, and these interviews were transcribed as well. The encounter that is presented here as a case study …
Open prostatectomy for benign prostatic enlargement in southern Europe in the late 1990s: A contemporary series of 1800 interventions
2002
Abstract Objectives Contemporary series of open prostatectomies from Western countries are rare. Frequently, the analysis of the outcome of open prostatectomy refers to old experiences or to series from developing countries. Any comparison with transurethral resection of the prostate can be invalidated by complications of open surgery because of the lack of an adequate healthcare system and technology. Methods The Sicilian-Calabrian Society of Urology performed a retrospective study to assess the surgical management of benign prostatic hyperplasia in Sicily and Calabria in 1997 and 1998. A three-page questionnaire was sent to the 36 urologic units of these two Italian regions with more than…
Effect of loperamide on jejunal electrolyte and water transport, prostaglandin E 2-induced secretion and intestinal transit time in man
1991
Jejunal perfusion was performed in 12 healthy volunteers to evaluate the dose dependent effects of loperamide on intestinal absorption, stimulated secretion and transit. In 6 volunteers intestinal perfusion of the jejunal segment with isotonic NaCl solution was followed by addition of loperamide in increasing doses (2–8 mg·l−1). The volunteers were pretreated with 1 mg·l−1 prostaglandin E2 (PgE2) in the perfusate before addition of 4 mg·l−1 loperamide. Phenolsulphonphtalein (PSP) boluses (2 ml) were given to measure mean transit time (MTT). Loperamide 2 mg·l−1 converted the minor secretion after perfusion with the standard solution (water −1.45 ml·min−1, Na −0.09 and Cl −0.04 mmol·min−1) to…
