Risk factors for intraoperative hypertensive crisis in patients with pheochromocytomas and sympathetic paragangliomas.

Purpose: To identify presurgical and surgical risk factors for intraoperative hypertensive crisis in patients with pheochromocytomas and sympathetic paragangliomas (PGLs) (PPGLs).

Methods: Retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. Intraoperative hypertensive crisis was defined as systolic blood pressure (SBP) greater than 200 mmHg lasting more than 1 min and postoperative hypertensive crisis as SBP greater than 180 mmHg or diastolic blood pressure (DBP) greater than 110 mmHg.

Predictive factors of six-week mortality in critically ill patients with SARS-CoV-2: A multicenter prospective study.

Objective: The objective of the study is to identify the risk factors associated with mortality at six weeks, especially by analyzing the role of antivirals and munomodulators.

Design: Prospective descriptive multicenter cohort study.

Setting: 26 Intensive care units (ICU) from Andalusian region in Spain.

Radioanatomical study of the extended free nasal floor mucosal graft and its clinical applications.

Objectives: To perform a radio-anatomical evaluation of the nasal cavity floor free mucosal graft (endonasal extended mucoplasty, EEM) to repair mucosal defects after an extended ethmoid-sphenoidotomy.

Methods: A human cadaveric study (radiological and anatomical dissection) and an in vivo study in surgical patients with CRSwNP were performed. The EEM areas were compared between 3D reconstruction from CT scans and anatomical/surgical dissections, both in cadaver specimens and in patients.

[Practical management of adalimumab].

Adalimumab, approved in the United States and Europe for the treatment of active rheumatoid and psoriatic arthritis and ankylosing spondylitis, might be used previously in the treatment of plaque psoriasis as "compassionate use drug." It should be remembered that its use should be in adults with moderate-severe psoriasis who, for some reason, do not tolerate or respond to the other existing systemic therapies or to phototherapy. Prior to its use, a detailed clinical history should be obtained with the study of the background of tuberculosis, and pregnancy and Mantoux tests should be performed.

[Extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae in spanish hospitals (GEIH-BLEE Project 2002)].

Introduction: To describe demographic aspects of a prospective multicentric nationwide study on Escherichia coli and Klebsiella pneumoniae producing extended spectrum b -lactamases (ESBL) in Spain, between March and June 2000.

Methods: 352 E. coli and K.

[Concentrations of calcium and bone remodeling biomarkers in umbilical cord blood and urine of newborn infants during delivery].

Objective: To evaluate calcium, phosphorus, parathormone (PTH), osteocalcin, and alkaline phosphatase concentrations in cord blood, pyridinoline concentrations in urine, and the pyridinoline/creatinine ratio in order to indirectly assess late bone remodeling in the newborn by comparing concentrations of these substances with those in the mother during the third trimester and delivery.

Patients And Methods: Calcium, phosphorus, PTH, osteocalcin, and alkaline phosphatase levels in cord blood, pyridinolines in urine and the pyridinoline/creatinine ratio were evaluated in 38 healthy pregnant women during the last two months of pregnancy and during delivery. To determine concentrations of these substances, samples from vein umbilical cord blood were obtained immediately after birth and urine samples were obtained from the neonates within 24 hours of delivery.

[Usefulness of ultrasonography in the diagnosis of portal hypertension].

Portal hypertension syndrome is a common evolutive complication of several hepatic and extrahepatic diseases, being liver cirrhosis responsible for more than 80% of cases. When diagnosed it has prognostic value because of the high incidence of hemorrhagic, metabolic and infectious complications that these patients may develop. Clinical suspicion must be confirmed by objective complementary studies that provide information about the etiology and severity of the disease.
