Management of Hyperkalemia in Heart Failure.

Hyperkalemia is a common electrolyte abnormality in heart failure (HF) that can cause potentially life-threatening cardiac arrhythmias and sudden cardiac death. HF patients with diabetes, chronic kidney disease and older age are at higher risk of hyperkalemia. Moreover, hyperkalemia is also often associated with the use of renin-angiotensin-aldosterone system inhibitors (RAASi) including angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, mineralocorticoid receptor antagonists and sacubitril-valsartan.

Materials And Methods: The study included dynamic computed tomography (CT) scans of 308 patients performed mainly for characterisation of liver and renal masses. Anatomic differences including the thickness of the diaphragmatic crus, the localisation of renal artery ostium at the wall of aorta, the level of renal artery origin with respect to superior mesenteric artery were evaluated.

Transseptal suturing technique in septoplasty: impact on bacteremia and nosocomial colonization.

Although effects of Merocel nasal packs and silicone splints on nasal flora alterations and bacteremia formation after septoplasty were assessed before, the effect of transseptal suturing technique has not been studied yet. The objective of this study is to compare nasal flora alterations and bacteremia occurrence rates between Merocel packs, silicone splints, and transseptal suturing technique in septoplasty. Ninety patients were divided into three groups randomly: Merocel packing (Group M), silicone splint (Group S), and transseptal suturing without packing (Group T).

Double steal phenomenon secondary to innominate artery occlusion.

Innominate artery steno-occlusive disease is a relatively rare clinical entity and may cause cerebrovascular symptoms. Herein, we report a 50-year-old male patient who presented with recurrent syncopal episodes and cerebrovascular ischemia. Color Doppler sonography revealed a distinctive flow pattern with partial and total flow reversal in the right internal carotid artery and vertebral artery, respectively.

The geriatric hand: correlation of hand-muscle function and activity restriction in elderly.

On the basis of the importance of hand manipulation in activities of daily living (ADL), deterioration of hand function because of various factors reduces quality and independence of life of the geriatric population. The aim of this study was to identify age-induced changes in manual function and to quantify the correlations between hand-muscle function and activity restriction in the geriatric age group, through grip and pinch measurements and a set of questionnaires. Twenty-four geriatric (aged 65-79 years) volunteers participated in the study.

Comparison of bony healing and cartilage degeneration following strut grafting and trapdoor procedures in an ovine model.

This experimental study compared bony healing and cartilage degeneration following strut grafting and trapdoor procedures for osteonecrosis of the femoral head in an ovine model. Osteonecrosis and a bony defect were created surgically in 16 hips of 8 Merino sheep, and the index grafting procedures were performed in a second session. Three months after surgery, the hips treated by strut grafting yielded better articular cartilage protection and bony healing compared to the osteonecrosis groups.

Incidence of pressure ulcers in intensive care unit patients at risk according to the Waterlow scale and factors influencing the development of pressure ulcers.

Aims: To determine incidence of pressure ulcers in patients at risk according to the Waterlow scale in intensive care units and to evaluate the effects of risk factors in critically ill patients.

Background: Pressure ulcers continue to be an important health problem that increases the risk of illness and death, extends patients' length of hospital stay and increases healthcare expenses.

Design: The study was conducted as a descriptive and prospective study.

Arnold-Chiari type I malformation presenting as benign paroxysmal positional vertigo in an adult patient.

Arnold-Chiari malformations are a group of congenital hindbrain and spinal cord abnormalities characterized by herniation of the contents of the posterior cranial fossa caudally through the foramen magnum into the upper cervical spine. It is important to recognize Arnold-Chiari type I malformation in the differential diagnosis of adult vertigo cases. We present a 51-year-old patient with Arnold-Chiari type I malformation that was initially diagnosed as posterior semicircular canal benign paroxysmal positional vertigo.

Acute upper gastrointestinal bleeding due to metastatic lung cancer: an unusual case.

There have been several published reports on metastatic lesions in the stomach, but the number of cases have been limited due to the low frequency of the condition. Metastatic lesions in the stomach are usually asymptomatic. A 55-year-old man with known metastatic lung adenocancer exhibited epigastric pain, hematemesis, and melena.

Background: The purpose of this study was to investigate whether polymorphism of N-acetyltransferase 2 (NAT2) genotypes are associated with the risk of laryngeal squamous cell carcinoma (SCC).

Methods: The study group consisted of 45 white patients with laryngeal SCC (42 men, with a mean age of 54 years [range, 37-70 years] and three women, with a mean age of 47 years [range, 32-55 years]) and 104 control subjects (68 men and 36 women; mean age, 50 years; range, 28-73 years). All of the patients were primarily treated with surgical intervention.

N-acetylcysteine inhibits peroxynitrite-mediated damage in oleic acid-induced lung injury.

Since oleic acid (OA) induces morphologic and cellular changes similar to those observed in human acute lung injury (ALI) and acute respiratory distress syndrome, it has become a widely used model to investigate the effects of several agents on pathogenesis of lung injury. The antioxidant and anti-inflammatory properties of N-acetylcysteine (NAC) has been documented in many lung injury models. In this study, we evaluated the role of NAC in an OA-induced lung injury model by measuring myeloperoxidase (MPO) activity, malondialdehyde (MDA) and 3-nitrotyrosine (3-NT) levels in lung tissue.
