Sleep disorders are common in patients with end stage renal disease receiving hemodialysis or peritoneal dialysis. However also a well functioning renal graft does not cure the poor sleep pattern which now emerges as a problem even in early chronic kidney disease (CKD). When patients are made aware for the first time of a disease such as CKD, which may brink to dialysis or at the best to a renal transplant patients begin to experience a disordered sleep. Sleeping disorders include insomnia (I), sleep apnoea (SAS), restless legs syndrome (RLS), periodic limb movement disorder (PLMD), excessive daily sleeping (EDS), sleepwalking, nightmares, and narcolepsy. Disordered sleep did not meet the clinical and scientific interest it deserves, in addition and we do not have a well defined solution for sleeping complaints. However, awareness that a poor sleep is associated with poor quality of life and carries an increase in mortality risk has recently stimulated interest in the field. There are many putative causes for a disordered sleep in chronic kidney disease and in end-stage renal disease. For a unifying hypothesis demographic factors, lifestyles, disease related factors, psychological factors, treatment related factors, and social factor must be taken into consideration.

We need a new health care system that is based on patients' needs. The present cadre of health managers who acquired power by cutting expenditures must be removed from office. We need to educate a new cadre of health managers who are 1) convinced that safeguarding health does not use up the resources of the next generations; 2) capable of switching the system from curative to preventive medicine; and 3) able to reinforce clinical research. Such principles have been recently adopted by the French President Sarkozy in devising the national health care program.

The ill deserve holistic care including assistance for the anxiety and fear generated by his illness. Illness may be viewed as a call for help, as the nocturnal side of life, or as a product of culture. All moments of the illness are precious, and its last instants may even reveal the infinite. The Western world is afraid of death--even now that our lives get longer--and abates the fear by removing the idea of death, even if poets have emphasized the richness it carries within.

A newly developed questionnaire was administered to 140 hemodialyzed patients (82 M and 58 F) who have achieved adequate anemia correction according to the best guidelines with the aim: to evaluate the prevalence of clinical/subclinical dyssomnias in these patients; to study the influence of the dialytic shift (morning versus afternoon schedules) on sleep duration and disturbancies; and to evaluate the relationship between clinical sleep disorders and blood pressure values in uremic patients. Results indicated that 85% of uremic patients undergoing hemodialysis complain of clinical insomnia (frequent, persistent and associated with daytime consequences) or sub-clinical sleep disorders; patients dialyzing in the morning sleep significantly less during the night preceding the treatment, than those dialyzing in the afternoon; older patients complaining of clinical insomnia have a higher risk of failure to achieve target-optimal values in systolic blood pressure.

The two words that mean sexual dysfunction, impotence and erectile dysfunction (ED), express two different concepts. Impotence is a general male sexual dysfunction that includes libidinal, orgasmic, and ejaculatory dysfunction. ED is the inability to achieve or maintain an erection sufficient to allow satisfactory sexual intercourse and is part of the general male sexual dysfunction termed impotence that includes libidinal, orgasmic, and ejaculatory dysfunction. Uremic men of different ages report a variety of sexual problems, including sexual hormonal pattern alterations, reduction in or loss of libido, infertility, and impotence, conditioning their well-being status. In evaluating and treating sexual dysfunction, a nephrologist must consider factors involved in its pathogenesis, such as hypothalamic-pituitary-gonadal axis alterations, psychological problems related to chronic disease, secondary hyperparathyroidism, anemia, autonomic neuropathy, derangements in arterial supply or venous outflow, and the normal structure of cavernous body smooth muscle cells. The introduction of sildenafil to treat impotent patients has completely changed the approach to evaluating these subjects because this drug is considered an effective well-tolerated treatment for men with ED. In the past, we proposed an algorithm that gave the opportunity to explore the previously mentioned factors using such instrumental interventions as the nocturnal penile tumescence test, penile echo color Doppler, nervous conduction velocity, and cavernous body biopsy, addressed to prescribe needed surgical or medical interventions. The complexity of the proposed algorithm requires many diagnostic procedures and much time and economic resources to localize the pathological lesions responsible for ED. Because of the new oral drug sildenafil, we propose a new algorithm to test the possibility of obtaining an erection and classify patients as responders or nonresponders to the sildenafil test.

Cardiovascular disease is the leading cause of morbidity and mortality in end-stage renal disease. Causes include those usually found in the general population, those related to the uremic status, and those related to dialytic treatment. Hypertension, hypotension, anemia, hypoalbuminemia, malnutrition, dyslipidemia, reactive C protein, calcium-phosphate product, dialysis modalities, and hyperhomocysteinemia are discussed extensively. Special emphasis is put on hyperparathyroidism as a traditional toxin. The emergent role of sleep apnea has been confirmed in animal models as well as in humans studied using polysomnography. There are difficulties in diagnosing coronary disease, because angiography is not risk-free, is expensive, and should be reserved for patients having symptoms of heart failure and/or patients having diabetes mellitus, and/or patients entering a transplantation list. This allows patients with coronary disease to undergo coronary artery bypass (preferably) or percutaneous transluminal angioplasty. Patients for whom surgery is not appropriate should be treated using more traditional medical procedures.

Salt is the last relic of the ocean where life was born. Its presence has influenced the whole gamut of history and its name is linked to hundred of geographical locations. Its importance for nutrition is supported by the discovery of Aeneolithic salt cellars. Salt cellars and pyramids of salt have been included in paintings and other works of art. In Japan where salt was and still is obtained from the sea, a salt culture has developed that can be traced in the rituals of everyday life, including meal preparation, sports, and Shinto ceremonies.

Many artists have used the symbol of salt in both religious and profane works, yet very few studies have explored the symbolism of salt as used in works of art. In this study, Panofsky's method has been adopted to evaluate works of art through an organic process articulated into three stages: (1) pre-iconographic, (2) iconographic and (3) iconological. The method was used for (a) religious paintings of the Old and New Testaments and (b) mythological and profane themes. Various salt-cellars were also studied. In particular, the paper examines the following themes: Isaac blessing Jacob, the return of Esau, Samuel consecrating David, the Last Supper, the suppers at Emmaus and at the house of Simon, the birth of St. John the Baptist, the Baptism of Constantine, the prodigal son, Bacchus-Apollo, the nuptial banquet of Love and Psyche, the death of the Cavalier of Celano, the king drinks, the landlord's visit, 'Phitopolis faisant servir des mets en or au roi Pithès', certain still life paintings and various salt-cellars including those of Cellini and Giulio Romano. The paper discusses the works of many artists including Raphael, Leonardo and his school (Boltraffio, Giampietrino, d'Oggiono, Solario), Hendricksz, Corenzio, Jean-Baptiste and Philippe de Champaigne, Damaskinos, Tintoretto, Titian, Romanino, Rubens, Bellini, Bloemaert, Veronese, Sustris, Just of Ghent, Jan Van Hemessen, Poussin, Loir, Giotto, Jordaens, Brueghel and Mimmo Paladino with his enchanted mountain. From the data examined it emerged that salt is a primary iconological presence in various works of art.
