Prospective Assessment of VI-RADS with Muscle Invasion in Urinary Bladder Cancer and Its Implication on Re-Resection/Restaging TURBT Patients.

Background: Bladder cancer (BCa) diagnosis relies on distinguishing muscle-invasive bladder cancer (MIBC) from non-muscle-invasive bladder cancer (NMIBC) forms. Transurethral resection of the bladder tumor (TURBT) is a standard procedure for initial staging and treatment. The Vesical Imaging-Reporting and Data System (VI-RADS) enhances diagnostic accuracy for muscle invasiveness through advanced imaging techniques, potentially reducing reliance on repeat TURBT and improving patient management.

Development of a robust and generalizable algorithm "gQuant" for accurate normalizer gene selection in qRT-PCR analysis.

The emergent role of nucleic acid-based biomarkers-microRNAs(miRNAs), long non-coding RNAs(lncRNAs), and messenger RNAs(mRNAs), is becoming increasingly prominent in disease diagnostics and risk assessment. qRT-PCR is the primary analytical method for quantitative measurement of biomarkers. Yet, the relative infancy of non-coding RNAs recognition as biomarkers poses a challenge due to the absence of a consensus on a universally accepted normalizer gene, an absolute requirement for accurate quantification.

Urinary extracellular vesicles-encapsulated miRNA signatures: A new paradigm for urinary bladder cancer diagnosis and classification.

Bladder cancer (BCa) stands as prevalent malignancy of the urinary system globally, especially among men. The clinical classification of BCa into non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC) is crucial for prognosis and treatment decisions. However, challenges persist in current diagnostic methods like Urine cytopathology that shows poor sensitivity therefore compromising on accurately diagnosing and monitoring BCa.

Role of Therapeutic Plasma Exchange in Guillain-Barre Syndrome after Allogeneic Hematopoietic Stem Cell Transplant: Report of Two Cases.

Background: Guillain-Barre Syndrome (GBS) is an acute inflammatory polyneuropathy characterized with rapid, progressive, ascending, and symmetrical weakness and areflexia. It is supposed to be an autoimmune disease related with production of antibodies by T lymphocytes activated against antigenic proteins of the peripheral nerves. Guillain-Barre Syndrome occurring after hematopoietic stem cell transplant (HSCT) has been associated with viral infections or toxic effects of chemotherapy.

Initial clinical experience with a powered circular stapler for colorectal anastomosis.

Background: The Echelon circular™ powered stapler (ECP stapler) obviates the need for manual firing of conventional circular staplers during the construction of a colorectal anastomosis, but has not been evaluated clinically. The aim of this study was to perform a clinical evaluation of this stapler.

Methods: A retrospective review of the initial clinical experience of a single surgeon using the ECP stapler for left-sided colorectal anastomosis construction during elective colorectal resections for benign and malignant disease was conducted by analyzing results from a prospectively maintained study database.

Antisocial personality disorder in Turkish substance dependent patients and its relationship with anxiety, depression and a history of childhood abuse.

The prevalence of antisocial personality disorder (ASPD) in treatment-seeking Turkish substance dependent patients and the relationship of ASPD with clinical characteristics were studied. Participants were 132 inpatients with substance dependence according to the Structured Clinical Interview for DSM-IV (SCID-I), Turkish version. The clinician applied a semi-structured socio-demographic form, SCID-I, SCID-II, Childhood Abuse and Neglect Questionnaire (CANQ), Michigan Alcoholism Screening Test (MAST), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI).

Clinical correlates of self-mutilation in Turkish male substance-dependent inpatients.

Objective: The aim of this study was to evaluate the prevalence of self-mutilation (SM) in male substance-dependent inpatients, and to investigate the relationship of SM with childhood abuse and neglect, axis I disorders and personality disorders.

Methods: Participants were 112 consecutively admitted male substance dependents (56 alcohol and 56 drug). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV (SCID-I, Turkish version).

Clinical correlates of childhood abuse and neglect in substance dependents.

The aim of this study was to evaluate the prevalence of childhood abuse and neglect (CAN) in Turkish substance dependents and to investigate the relationship between CAN with axis I disorders, personality disorders and severity of depression and anxiety symptoms. Among 132 substance dependents, 56.1% met dichotomous criteria for some form of CAN.

[Tamponade caused by localized compression of the superior vena cava and right atrium after aortic valve replacement under extracorporeal circulation].

The authors report a case of localised compression of the right atrium due to a loculated intrapericardial haematoma after open heart surgery. The patient suddenly developed signs of superior vena caval obstruction during the third postoperative week. The diagnosis was made by 2D echocardiography and superior vena cavography.

An asanguineous reperfusion solution. An effective adjunct to cardioplegic protection in high-risk valve operations.

The protection afforded by cardioplegia during elective ischemic arrest can be partly compromised by a reperfusion injury, which may impede the recovery of cardiac function. We previously showed experimentally that this postischemic damage could be largely avoided by an appropriate crystalloid reperfusate. The present study was thus undertaken to assess the effects of this "reperfusion solution" clinically.

Radionuclide assessment of cardiac function. Pre-operative evaluation of patients with abdominal aortic occlusive disease undergoing aortobifemoral bypass grafting.

Pre-operative radionuclide angiography, a non-invasive technique for evaluating ventricular function, was performed on 34 consecutive patients undergoing aortobifemoral bypass grafting for abdominal aortic occlusive disease, to determine whether pre-existing coronary artery disease causes significant modification of cardiac function. Patients were divided into two groups according to medical history. Group I had 23 patients with no symptoms of coronary artery disease and Group II had 11 patients, six with previous myocardial infarction and five with angina pectoris.

[Treatment of cardiogenic shock in acute myocardial infarction and postoperative low cardiac output].

The extent of myocardial and coronary lesions, the failure of the mechanisms regulating coronary blood flow, and the inadequacy of adrenergic stimulation account for the difficulties in managing cardiogenic shock as a complication of acute myocardial infarction. Except in cases of hypovolemia, excessive bradycardia, the only adequate treatment is IABP. However, long-term survival is observed only in patients undergoing surgery for a mechanical complication after control of the cardiogenic shock.

[Acute rupture of the left ventricle 12 hours after an anteroseptal myocardial infarct. Successful surgical repair].

Acute rupture of the left ventricular free wall was suspected in a 53 year old hypertensive patient at the 12th hour of primary antero-septo-apical myocardial infarction. He developed acute tamponade with severe cardiogenic shock during his transfer to hospital. Cardiac compression due to hemopericardium was confirmed by M mode echocardiography (pericardial effusion), right heart catheterisation (adiastole and low cardiac output) and pericardial puncture during which several ccs of blood were aspirated leading to a slight improvement in the patient's condition.

Retrograde coronary sinus perfusion: a safe alternative for ensuring cardioplegic delivery in aortic valve surgery.

During aortic valve surgery, cardioplegic solution is delivered through direct cannulation of both coronary ostia. Since this approach may cause an intimal injury leading to acute dissection or late ostial stenosis, we have evaluated retrograde coronary sinus perfusion (RCSP) as a means of delivering cardioplegia in 12 patients undergoing aortic valve replacement. The retroperfusion of the cardioplegic solution was performed with a balloon-tipped catheter inserted into the coronary sinus through the right atrium.

Acute left ventricular rupture secondary to myocardial infarction. Report of long-term survival after early surgical repair.

The case of a 53-year-old male patient is presented who experienced acute left ventricular rupture 12 hours after a myocardial infarct. Immediately following emergency right heart catheterization and pericardiocentesis the patient was operated upon after preliminary institution of femoro-femoral partial heart-lung bypass. Left ventricular rupture in the area of an apical infarct was found which was successfully treated by direct closure.

[Aorto-left ventricular discontinuity of infectious origin. Problems of surgical repair].

Aorto-left ventricular discontinuity may result from destruction of the aortic ring in aortic valve endocarditis, making solid implantation of a valvular prosthesis difficult. We believe the best technique to be the insertion of a valved Dacron tube from a noninfected area of the left ventricle to the ascending aorta distal to the coronary ostia, the coronary arteries being reimplanted in the tube. This technique implies a relatively dilated aortic ring and the integrity of the supra-annular aortic wall.

Effects of intrinsic sympathetic activity of beta-blockers on SA and AV nodes in man.

The authors compare the effects of beta-blockers without intrinsic sympathetic activity (ISA) (propranolol, 160 mg/day), moderate ISA (acebutolol, 800 mg/day) and high ISA (pindolol, 20 mg/day). The sinus rate decreases more with propranolol than with acebutolol, during the day (P less than 0.01) and during the night (P less than 0.
