Management of proximal tibial fractures is a challenging issue in patients with rheumatoid arthritis (RA). In the present study, we aimed to describe our experience of acute total knee replacement in RA patients.This case series included 11 RA patients with simultaneous insufficiency fractures of the proximal tibia, who were treated by acute total knee replacement. Midterm functional results, severity of pain, Hospital for Special Surgery (HSS), and Knee Society Score (KSS) parameters were evaluated in this study...

Unicompartmental knee arthroplasty (UKA) is a recognized procedure for treatment of medial compartment osteoarthritis. Patellofemoral (PF) joint degeneration is widely considered to be a contraindication to medial compartment UKA. We examined the validity of this preconception using information gathered prospectively on 147 consecutive patients who underwent the Repicci II UKA for medial compartment osteoarthritis between July 1999 and September 2000 by the same surgeon. The status of the PF joint was assessed intraoperatively in all patients, and accordingly patients were divided into two groups...

Small cell lung cancer (SCLC) is an aggressive subtype of lung cancer characterized by rapid growth and early spread. It is a highly lethal disease that typically is diagnosed at a late stage. Surgery plays a very small role in this cancer, and management typically involves chemotherapy, delivered with thoracic radiation in early-stage disease. Platinum-based chemotherapy is initially very effective, inducing rapid and often deep responses. These responses, though, are transient, and upon relapse, SCLC is highly refractory to therapy...

The oligometastatic and oligoprogressive disease states have been recently recognized as common clinical scenarios in the management of non-small cell lung cancer (NSCLC). As a result, there has been increasing interest in treating these patients with locally ablative therapies including surgery, conventionally fractionated radiotherapy, stereotactic ablative radiotherapy, and radiofrequency ablation. This article provides an overview of oligometastatic and oligoprogressive disease in the setting of NSCLC and reviews the evidence supporting ablative treatment...

Enhanced recovery programs (ERPs) aim to reduce psychological and physiological stress related to surgery, and minimize opioid use. This article describes the tenets of enhanced recovery, the guidelines for ERP in lung surgery, and the University of Virginia experience with developing and implementing a program. The impact of these strategies on short-term patient outcomes and potential long-term benefits including influence on lung cancer-specific outcomes are reviewed. The opioid crisis is of utmost importance; this article will explore how ERPs may be a mitigating factor...

Locally advanced, stage IIIA-N2 Non-small cell lung cancer (NSCLC) represents a heterogeneous patient population. Considerable controversy exists as to the optimal management of these patients. Local therapy alone with a single modality, namely surgery or radiation, is associated with high recurrence rates and low overall survival. Consequently, multimodality treatment (chemotherapy, radiotherapy, with or without the utilization of surgery) has developed as a means of both local and systemic control for patients with stage IIIA-N2 NSCLC, and has led to improved overall survival...

Lung carcinoma widely affects men and women in the sixth and seventh decades of life. Thorough workup with radiographic imaging, pathologic diagnosis, and cardiopulmonary functional assessment is key to successful treatment. Accurate staging is essential for both assessing prognosis and directing therapy. Early-stage lung cancer is most often treated with anatomic lobectomy; locally advanced cancers may require induction or adjuvant therapies. Any nonnodal metastases will require definitive systemic therapy...

INTRODUCTION:  Ureteric reimplantation due to ureterovesical junction (UVJ) obstruction enjoys high success in the short term. However, renal function after reimplantation must accommodate the numerous changes in the pediatric urinary tract that occur along with child development that may theoretically cause an occult loss of renal function. The purpose of this study was to evaluate whether improved renal function after ureter reimplantation for antenatal diagnosed UVJ obstruction remains stable after puberty...

BACKGROUND: Multifocal intraocular lenses (MIOLs) may bring independence from glasses. In practice the question often arises as to which patient would be suitable for the implantation of MIOLs. Surgeons are hesitant to implant MIOLs in patients with macular or retinal pathologies, mostly due to a fear that the multifocality of the implanted IOL might increase patients' existing visual handicap. In this study we use virtual implantation to determine how various multifocal intraocular lens designs impact visual performance in the presence of macular pathologies...

OBJECTIVE: There are a few studies in the literature investigating the effect of preoperative dutasteride use on bleeding in open simple prostatectomy. We aimed to evaluate the effect of preoperative dutasteride use on perioperative bleeding during open simple prostatectomy. METHODS: We retrospectively analyzed the medical records of all patients who underwent transvesical open prostatectomy due to benign prostatic hyperplasia in our institution between 2008 and 2018...

The neuropeptide oxytocin has emerged as a promising pharmacotherapy for methamphetamine (METH) addiction, and clinical trials of intranasal oxytocin are underway. However, there is debate as to how peripherally administered oxytocin alters brain signalling to modulate addiction processes. Interestingly, there is evidence for functional interactions between peripheral oxytocin administration and the vagus nerve. Therefore, this study investigated whether the effects of peripherally administered oxytocin require vagal signalling to reduce METH self-administration and reinstatement of METH-seeking behaviours...

INTRODUCTION: There are gaps in literature regarding outcome of multiple polyps and dilemmas in the management issues in polyposis syndromes in children. OBJECTIVE: We aimed to study the clinical behaviour of gastrointestinal (GI) polyps with emphasis on therapeutic outcomes of polyposis syndrome. METHODS: Proven cases of GI polyp(s) on endoscopy were classified as, single polyp, multiple polyps and polyposis syndrome. Complex presentation was defined as one or more of the following: severe anemia, anasarca, intussusception, rectal mucosal prolapse, diarrhea...

OBJECTIVES: To investigate the optimal treatment and prognosis of thalamic glioma in adult patients. PATIENTS AND METHODS: We retrospectively analyzed the adult patients with thalamic glioma admitted to our hospital from May 2005 to September 2016. Patients were divided into two groups according to their treatment: surgery-based combined treatment and intensity modulated radiation therapy (IMRT)-based treatment. Univariate chi-square test and multivariate logistic regression were used to identify independent factors for the treatment modality...

Replacement therapy with concentrates of factor VIII or IX remains the gold standard for severe haemophilia management. The recent development of clotting factor products with extended half-life, widely available on the market since 2 years, facilitates adherence, improves considerably the patients' quality of life, and simplifies the management of breakthrough bleedings or surgery. These molecules have also brought to the limelight the concepts of optimization and personalization of anti-haemophilic prophylaxis...

BACKGROUND: The handover period has been identified as a particularly vulnerable period for communication breakdown leading to patient safety events. Clear and concise handover is especially critical in high-acuity care settings such as trauma, emergency general surgery, and surgical critical care. There is no consensus for the most effective and efficient means of evaluating or performing handover in this population. We aimed to characterize the current handover practices and perceptions in trauma and acute care surgery...

INTRODUCTION: Intestinal parasitic infections are a health burden to developing countries, but can also become more prevalent worldwide, even in developed countries, with the advent of globalization. While most of these infections are benign, some may be associated with acute infections with high morbidity and mortality rates. CASE PRESENTATION: A 36 years old patient presented with toxic megacolon with poly-helminthic infections, likely a result of raw food ingestion...

In the present study, we evaluated an autologous bone graft substitute (ABGS) composed of recombinant human BMP6 (rhBMP6) dispersed within autologous blood coagulum (ABC) used as a physiological carrier for new bone formation in spine fusion sheep models. The application of ABGS included cervical cage for use in the anterior lumbar interbody fusion (ALIF), while for the posterolateral lumbar fusion (PLF) sheep model allograft devitalized bone particles (ALLO) were applied with and without use of instrumentation...
