The authors present a case of a 62-year-old woman who was hospitalized with severe medical problems that included congestive heart failure secondary to mitral stenosis and atrial fibrillation, coronary artery disease, chronic renal failure, and a recent history of a right cerebral lacunar infarction. She also had a 2-year history of anxiety and depression, manifested in the hospital by frequent crying spells, sleeplessness, and ruminating about her illnesses. The patient received buspirone 5 mg three times a day for her anxiety and depression. Approximately 12 hours after her first dose, she developed dramatic myoclonus, dystonias, and akathisia. She was given 25 mg of intramuscular diphenhydramine and 1 mg of intramuscular benztropine mesylate, which resulted in little relief; however, 1 mg clonazepam caused both the myoclonic jerks and dystonias to resolve completely.

Anemia is an inevitable and potentially serious complication of chronic renal failure and one of the most important limiting factors in patient rehabilitation. Although adequate dialysis can control many of the symptoms of uremia, dialysis does not reverse anemia-associated fatigue, and thus, many patients are not rehabilitated. Human recombinant erythropoietin (epoetin) therapy has proven to be effective in reversing anemia and increasing hematocrit levels in the majority of patients with chronic renal failure. Among this patient population, increases in hematocrit level have resulted in improvements in the symptomatology of organ hypoxia, neurobehavioral indices, anorexia, insomnia, depression, and sexual disinterest and dysfunction, as well as a reduction in cardiomegaly. However, despite the availability of epoetin and the dramatic improvements in the complications associated with the anemic state observed following therapy, it appears that patient rehabilitation remains a challenge. One aspect of the continuing problem of rehabilitation appears to be the reluctance of the medical community to increase hematocrit levels above 30%, despite the fact that higher hematocrit levels are associated with greater improvements and that potential adverse events related to hemodynamic adaptation are manageable. Indeed, a comparison of the results from two Epoetin alfa clinical trials, one in which hematocrit levels were maintained at 35% and a large phase IV study in which the target hematocrit level appears to have been approximately 30%, clearly demonstrate the benefits of optimizing hematocrit levels and thus improving the potential for rehabilitation.

Restless legs syndrome is a common condition characterized by unpleasant limb sensations that are precipitated by rest and relieved by activity. Symptoms are worse during the evening and may result in insomnia. Most cases are idiopathic, although the condition is sometimes familial and may be associated with a range of medical illnesses, including chronic renal failure and iron deficiency anemia. Restless legs syndrome is responsive to several medications, including levodopa, dopamine agonists, benzodiazepines, opioids, and some anticonvulsants. A practical approach to management involves a stepwise plan, commencing with intermittent therapy with less potent agents for mild cases and progressing to medications with greater potency but a higher potential for side effects.

Sleep apnea is a surprisingly common disorder in end-stage renal disease (ESRD) and chronic renal failure. The symptoms of sleep apnea frequently go unreported or may be misdiagnosed as uremia, depression, chronic illness, or insomnia. A review of the literature was performed to define the prevalence, morbidity, and treatment of sleep apnea syndrome in the ESRD patient. Sleep apnea occurs in at least 60% of ESRD patients. The known complications of sleep apnea include arrhythmias, pulmonary hypertension, and systemic hypertension. In addition, sleep apnea has been implicated in coronary artery disease and strokes. The contribution of sleep apnea to the high mortality from cardiac disease and stroke in peritoneal dialysis and hemodialysis patients is unknown. The causes of the increased prevalence of sleep apnea in ESRD patients are unknown and likely differ from the general population, but the treatment is similar. The literature suggests that modality of renal replacement therapy does not matter; however, large nocturnal volume peritoneal dialysis may worsen sleep apnea. Renal transplantation may be curative. In conclusion, sleep apnea may be an under-diagnosed disease in patients on dialysis. There are significant reasons to suspect that sleep apnea may worsen the morbidity and mortality of ESRD, and there are potential successful therapies.

We'll report 2 dialysis cases which came to our clinic for the symptoms caused by hypercalcemia. Patients complained of sleeplessness, itching, headache, palpitation, apathy, akinesis, leanness, foot gangrene and so on. Hypercalcemia is one of the complication of vitamin D and calcium carbonate administration in chronic renal failure, though the frequency and risk are not clearly documented. Hypercalcemia aggravates the outcome of patients on dialysis and contributes to vascular calcification in long term. Recently various factors involving cardiovascular calcification are discussed, but first of all we must be very careful for the symptoms of hypercalcemia, and careful monitoring of plasma calcium concentration are recommended.

A 66-year-old man with no medically remarkable past or family history gradually showed personality changes, memory disturbance, sleeplessness and abnormal behavior. Neurologic examination showed no focal signs and neither parkinsonism nor cerebellar ataxia was recognized. He died 4 years after the onset of dementia due to chronic renal failure. Neuropathologic examination revealed neuronal loss and gliosis in the temporal cortex, particularly in the subiculum, parahippocampal gyrus and entorhinal cortex, and insular cortex. NFTs were observed to be widespread in the cerebral cortex, especially the temporal cortex and brainstem, while senile plaques were not observed. Gallyas-Braak silver staining revealed the presence of numerous NFTs, glial inclusions and neuropil threads throughout the cerebral neocortex, limbic system, hippocampus and brainstem. The subiculum showed the most severe involvement; severe atrophy, severe neuron loss, and numerous ghost tangles (extracellular NFTs) were apparent. Although NFTs contained both monoclonal anti-3repeat-tau antibody (RD3) and RD4 immunoreactivity, this differed between the intracellular NFTs and ghost tangles. RD3 immunoreactivity was mainly observed in ghost tangles and neuropil threads, whereas RD4 immunoreactivity was mainly observed in intracellular NFTs and glial inclusions. Calcification was also found to be widespread in the cerebral cortex and white matter, basal ganglia, thalamus, cerebellar cortex, white matter and dentate nucleus. These characteristic neuropathologic findings lead to the pathologic diagnosis of diffuse neurofibrillary tangles with calcification (DNTC). It is argued that this patient showed early stage pathologic signs of DNTC due to a short disease duration, which may provide clues regarding the progression of this rare disease.

Restless legs syndrome (RLS) is an extremely distressing problem experienced by patients on dialysis; the prevalence appears to be greater than in the general population, with a wide variation from 6.6% to 80%. The diagnosis of RLS is a clinical one, and its definition has been clarified and standardized by internationally recognized diagnostic criteria, published in 1995 by the International Restless Legs Syndrome Study Group (IRLSSG). This study was designed to find out the prevalence of RLS in Saudi patients with end-stage renal disease (ESRD) on maintenance dialysis. This is a cross sectional study carried out between May and Sept 2007 at two centers, King Abdulaziz Medical City-King Fahad National Guard Hospital (KAMC-KFNGH), Riyadh and King Faisal Specialist Hospital and Research Centre (KFHRC), Jeddah, Saudi Arabia. Data were gathered on 227 Saudi patients on chronic maintenance hemodialysis or chronic peritoneal dialysis. The prevalence of RLS was measured using IRLSSG's RLS Questionnaire (RLSQ). Potential risk factors for RLS including other sleep disorders, underlying cause of chronic renal failure, duration on dialysis, dialysis shift, biochemical tests and demographic data were also evaluated. The overall prevalence of RLS was 50.22% including 53.7% males and 46.3% females. Their mean age was 55.7 +/- 17.2 years and mean duration on dialysis 40.4 +/- 37.8 months. Significant predictors of RLS were history of diabetes mellitus (DM), coffee intake, afternoon dialysis, gender and type of dialysis (P= 0.03, 0.01, < 0.001, 0.05 and 0.009 respectively). Patients with RLS were found to be at increased risk of having insomnia and excessive daytime sleepiness (EDS) (P= < 0.001 and 0.001, respectively). Our study suggests that RLS is a very common problem in dialysis population and was significantly associated with other sleep disorders, particularly insomnia, and EDS. Optimal care of dialysis patient should include particular attention to the diagnosis and management of sleep disorders.

Hypertension can cause or promote renal failure and is related to cardiovascular mortality, the major cause of death in patients with renal impairment. Changes in the circadian BP pattern, particularly the blunting or reversal of the nocturnal decline in BP, are common in chronic renal failure. These changes in turn are among the major determinants of left ventricular hypertrophy. Using a chronobiological approach, it is possible to obtain better insight into the reciprocal relationship between hypertension, renal disease, and increased cardiovascular risk of renal patients. Disruption of the normal circadian rhythm of rest/activity may be hypothesized to underlie the high cardiovascular morbidity and mortality of such patients. Epidemiological studies reveal that hemodialysis patients experience poor subjective sleep quality and insomnia and, in comparison to healthy persons, are more likely to show shorter sleep duration and lower sleep efficiency. Sleep apnea may be present and is usually investigated in these patients; however, the prevalence of restless legs syndrome (RLS), which is high in dialysis patients and which has been associated with increased risk for cardiovascular disease in the general population, could also play a role in the pathogenesis of sleep-time hypertension in renal patients. Careful assessment of sleep quality, in particular, diagnostic screening for RLS and periodic limb movements (PLM) in renal patients, is highly recommended. In renal failure, attention to sleep quality and related perturbations of the sleep/wake cycle may help prevent the occurrence and progression of cardiovascular disease.

"Do the sociodemographic characteristics relate to the levels of depression and anxiety in patients with chronic renal failure in Athens?" The study investigated in a group of renal disease patients differences referring to self-reported mental health, depression, and anxiety, after controlling for gender, age, education, and marital status. Patient-reported assessments included General Health Questionnaire (GHQ-28) of Goldberg, Center for Epidemiological Studies Depression Scale (CES-D), and State-Trait Anxiety Inventory (STAI I & II) of Spielberger. Female patients reported higher scores in the trait anxiety measure. Elder patients reported higher scores in the GHQ-28 subscale of social dysfunction and in the CES-D depression scale, while less educated patients presented higher scores in the GHQ-28 subscales of anxiety/insomnia and severe depression. Divorced/widowed patients presented higher scores in the severe depression subscale. Findings provide evidence that sociodemographic variables, like being older, less educated, and divorced/widowed, relate to a more compromised mental health.

The term chronic renal failure (CRF) usually means the final stage of chronic kidney disease (CKD) with a decline in glomerular filtration rate (GF) below 0.25 mL/s. CRF is a world-wide serious health and economic issue with an increasing incidence and prevalence. CRF patients are, in comparison to other patients, hospitalized more often and for longer and, despite improvements in care, their quality of life is usually low and morbidity and mortality high. We present an overview of the most important CKD risk factors and the diseases most likely to result in CRF. Diabetic nephropathy, followed by various forms ofischemic renal disease and primary and secondary glomerulopathy, chronic tubulointerstitial nephritis and autosomal dominant polycystic kidney disease are the leading causes of CRF. We provide a brief overview of other disease states that may result in renal failure. Clinical manifestations of CRF are discussed, mainly cardiovascular, gastrointestinal, haematological and neurological symptoms. Breathlessness is a consequence of hypervolaemia, metabolic acidosis and anaemia. The disease often presents with symptoms, such as headache and visual disturbances, resulting from arterial hypertension. Gastrointestinal symptoms and fatigue, usually caused by anaemia, are frequent. Platelet dysfunction is manifested as an increased bleeding time. Paradoxically, apart form tendency to abnormal bleeding, CRF also tends to be associated with thromboembolic complications. Patients may experience itching, bone, joint and muscle aches, are more prone to infections. They may suffer from insomnia, concentration disorders and apathy. The signs of peripheral mixed sensory-motor neuropathy include paraesthesia, paresis and restless leg syndrome. However, renal failure may also be oligosymptomatic or asymptomatic. Cardiovascular complications are the most frequent cause of morbidity and mortality of CRF patients.
