Shota Takenaka, Hiroyuki Aono
BACKGROUND: Drop foot resulting from degenerative lumbar diseases can impair activities of daily living. Therefore, predictors of recovery of this symptom have been investigated using univariate or/and multivariate analyses. However, the conclusions have been somewhat controversial. Bayesian network models, which are graphic and intuitive to the clinician, may facilitate understanding of the prognosis of drop foot resulting from degenerative lumbar diseases. QUESTIONS/PURPOSES: (1) To show a layered correlation among predictors of recovery from drop foot resulting from degenerative lumbar diseases; and (2) to develop support tools for clinical decisions to treat drop foot resulting from lumbar degenerative diseases...

Retrospective analysis on 312 patients, operated for thyroid nodules between 2014 and 2015, was conducted to evaluate the impact of frozen section analysis on the strategy of thyroid nodule surgery. One hundred and ninety-three patients were included. They all underwent preoperative US, fine needle aspiration cytology (FNAC), per operative frozen section (FS) and post operative definitive pathological analysis. Se, Sp, VPP and VPN of FNAC and FS were calculated and compared (McNemar's test). Multivariate analysis was performed to identify independent factor of good results...

BACKGROUND: Myocardial tolerance to ischemia is influenced by age and preoperative cyanosis through unknown mechanisms and significantly affects postoperative outcomes. Cytochrome c oxidase (CcOx), the terminal enzyme of the mitochondrial electron transport chain, may play a role in the susceptibility to ischemic-reperfusion (IR) injury. Our study aimed at investigating changes in human myocardial CcOx activity based on age and preoperative oxygen saturation to understand its role in transition from neonatal to mature myocardium and hypoxic conditions...

OBJECTIVE: Postoperative bleeding after cardiac surgery is commonly associated with hyperfibrinolysis. This study was designed to evaluate the efficacy of topical tranexamic acid in addition to intravenous tranexamic acid in reducing bleeding in cardiac surgery cases. METHODS: From July 1, 2014 to September 30, 2015, 82 patients who underwent elective on-pump cardiac surgery were randomized into a tranexamic acid group and a placebo group. In the tranexamic acid group, 1 g of tranexamic acid dissolved in 100 mL of normal saline solution was poured into the pericardium during sternal closure; the placebo group had 100 mL of saline only...

Blood transfusion remains an important therapeutic intervention in patients with sickle cell disease (SCD), aiming to both increase the oxygen carrying capacity of blood and to reduce the complications of vaso-occlusion. Simple, manual exchange and automated exchange can be effective in reducing the acute and chronic complications of SCD, and the advantages and disadvantages of each methodology mean they all have a role in different situations. Evidence for the role of emergency transfusion in the management of the acute complications of SCD, including acute pain and acute chest syndrome, comes from observational data...

BACKGROUND/AIMS: Progression of a fovea-on to a fovea-off rhegmatogenous retinal detachment (RRD) while awaiting surgery is rare. METHODS: A retrospective review of patient records to identify patients in whom a fovea-on retinal detachment at presentation was found to be fovea off at surgery. RESULTS: We identified 10 cases over 14 years which converted from fovea-on to fovea-off RRD while awaiting surgery. This represented 1.1% of RRDs that were fovea on at presentation (n=930)...

PURPOSE: To study the relationship between the size of primary full-thickness macular hole (MH) and the vitreomacular attachment status. DESIGN: Single-centre retrospective observational case series. METHODS: The records of 100 consecutive eyes operated for primary full-thickness MH were retrospectively reviewed. The vitreous status and MH diameter were assessed on the preoperative optical coherence tomography scans. MH were classified depending on the presence or absence of vitreomacular traction (VMT) and their size as small (<250 µm), medium (250-400 µm) and large (>400 µm), as suggested in the International VMT Study Group Classification...

Minimally invasive aortic valve replacement (mini-AVR) procedures are a valuable alternative to conventional open heart surgery. Currently, planning of mini-AVR consists of selection of the intercostal space closest to the sinotubular junction on preoperative computer tomography images. We developed an automated algorithm detecting the sinotubular junction (STJ) and intercostal spaces for finding the optimal incision location. The accuracy of the STJ detection was assessed by comparison with manual delineation by measuring the Euclidean distance between the manually and automatically detected points...

BACKGROUND: In order to prevent postoperative dislocation due to prosthetic impingement as a result of total hip arthroplasty (THA), the combined anteversion (CA) theory, which combines the anteversion of the femoral stem and the acetabular socket, has been revised in recent years. Particularly, it is necessary to keep CA within the target zone. METHODS: The aim of this study was to investigate whether postoperative CA can be kept within the target zone while using the operative technique which prepares the socket first in cementless THA, by estimating the anteversion of the metaphyseal fit stem or the shorter, tapered wedge stem using preoperative 3-dimensional computerized planning, and by adjusting the anteversion of the socket using a navigation system that considers CA...

Acupuncture has been used in the Far East for more than 2000 years. Since the early 1970s, this technique has been gaining popularity among Western medical community. A number of studies suggest that its mechanism of effect can be explained in biomedical terms. In this context, a number of transmitters and modulators including beta-endorphin, serotonin, substance P, interleukins, and calcitonin gene-related peptide are released. For that reason, acupuncture can be used in a wide variety of clinical conditions...

Platinum-based perioperative chemotherapy is actually the standard of care in stage II-IIIa non-small cell lung cancer (NSCLC). A benefit may also be seen in stage IB NSCLC with tumors of more than 4cm of diameter. Perioperative chemotherapy improves 5-year survival of 4 to 15%. This benefit is mainly proved by postoperative chemotherapy trials. Nevertheless, preoperative chemotherapy has advantages: a better tolerance, an estimation of tumor chemosensibility, without an increased postoperative morbimortality...

BACKGROUND: Renal vein anomalies are relatively infrequent and generally asymptomatic. Preoperative knowledge of such variants is, however, of paramount importance in several angiographic and surgical procedures including renal venography, renal vein sampling, spermatic embolization, and renal transplantation. Inadequate knowledge and failure to recognize such anatomic variations may lead to several operative hazards including hemorrhage, nephrectomy, and even death. CASE PRESENTATION: We report a case of bilateral anomalous drainage of the posterior divisions of renal veins into the azygos venous system in a 20-year-old woman of African descent from Tanzania who presented to us with a 12-year history of recurrent anemia...
