Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation the aorta should be considered. older primary aldosteronism, obstructive sleep apnoea artery stenosis are more prevalent than previously thought. Primary aldosteronism can screened by taking morning aldosterone renin levels, considered with severe, resistant or hypokalaemia-associated hypertension. Symptoms sought. Worsening function after...

Increasing numbers of elderly patients are undergoing long-term dialysis. However, the role dialysis in survival and quality life is unclear, poor outcomes may be associated with comorbidities rather than age only. The initiation unplanned chronic kidney disease (CKD) has been reported to survival. We evaluated patient practice factors performed a retrospective analysis 90 consecutive (≥75 years) CKD initiated on at our renal unit between October 2010 February 2014. Six were excluded; data...

Chronic kidney disease (CKD) causes bone and mineral disorders alterations in vitamin D metabolism that contribute to greater skeletal fragility. Hip fracture elderly is associated with significant morbidity mortality. The aim of this study was investigate the outcome patients non-dialysis dependent CKD hip undergoing surgery.Retrospective IRB approval above 65 years age, fractures admitted between June 2014 2016 a Southeast Asian cohort. Data collected included demographic variables...

Introduction Patients who had a stroke are at increased risk of sepsis, dehydration and fluctuations in blood pressure, which may result acute kidney injury (AKI). The impact AKI on long-term survival has not been studied well. Objective We aimed to identify incidence during stroke, follow-up period its development chronic disease (CKD). Design, setting participants Retrospective analysis patients admitted the rehabilitation facility Changi General Hospital, Singapore, between June 2008 May...

A 75-year-old female with end stage kidney failure had her tunneled central venous dialysis catheter (CVC) removed. subsequent computed tomopgraphy (CT) scan of the chest reported a filling defect in vein that appeared to represent fractured remnant CVC. The been retained for culture and was available direct visualization, which showed it be entirely intact. venogram confirmed CT findings represented calcified fibrin sheath. As CVC fragments may require intervention, this diagnosis should...

Central venous catheters are extensively used in critical care units and dialysis centres to gain access the blood stream for purpose of invasive monitoring, drug administration, parenteral nutrition perform renal replacement therapy. One common areas central catheter insertion is right internal jugular vein due its anatomical continuity with superior vena cava. The complication rates can be more than 15%, including early late complications.We present an unusual recurrent laryngeal nerve...

Juvenile xanthogranuloma is a rare benign lesion occurring in infancy and childhood. Despite the term juvenile xanthogranuloma, onset during adulthood can occur with peak incidence second third decades of life (Tahan et al, 1989). It characterized by single or multiple cutaneous nodules, which show spontaneous involution. commonly mistaken for malignant lesion. The authors report case nose an adult, was excised diagnostic cosmetic reasons. This first reported xantho-granuloma adult.

Introduction: Vitamin D deficiency is common in chronic kidney disease (CKD) and associated with lower bone mineral density (BMD), decreased muscle strength, increased hip fracture risk. Guidelines have suggested targeting 25-OH vitamin (25(OH)D) levels between 20 30 ng/ml. However, metabolism altered CKD, threshold for optimal BMD are unknown. Methods: We included 1097 patients fractures. CKD was defined as estimated glomerular filtration rate <60 ml/min/1.73 m (Mucsi et al., Clin....

A 54-year-old man on maintenance hemodialysis with recurrent catheter-related bloodstream infections due to Staphylococcus aureus was admitted. Multiple prior transthoracic echocardiograms failed reveal any vegetation. Subsequently transesophageal echocardiography a mass consistent fibrin sheath vegetations identified and follow-up diagnostic computed tomography (CT) venogram confirmed the presence of vegetations.
