[Daily short dialysis. First results in a group of patients in home dialysis training].

The preliminary data of a small group of voluntary patients in daily short dialysis according to Buoncristiani are reported. After only one month of therapy an increase of haemoglobin and of haematocrit was obtained so that it was possible to reduce the EPO dose. The arterial pressure was better controlled with a smaller dose of antihypertensive drugs, facilitated in one case by a marked reduction of the body weight. The improvement in well-being and libido has been better than expected. The good results achieved encourage to go on with this experience, reported in the literature as an advantageous method both from the theoretic and clinical point of view, despite some difficulties that have still to be minimised.

[Conservative treatment of renal ptosis].

BACKGROUND: Nephroptosis or floating kidney is an acquired, caudal displacement of one or both kidneys, with differing stages and etiology. It has been almost completely ignored over the past few years. The general tendency to regard nephroptosis as a urological pathology has prompted researchers to look for resolutive surgical treatment. The existence of over 150 surgical techniques is a clear demonstration of the high failure rate with the result that surgeons are unwilling to tackle this pathology, often leaving the patient alone with his problems. The numerous nephrological complications caused by nephroptosis have prompted us to look for alternative therapies to propose to nephrologists for the consecutive treatment of the floating kidney, enabling the patient to live with his pathology. METHODS: A longitudinal study was performed for 60 months in 102 patients with mono or bilateral nephroptosis. Hematuria, urinary cylindroids, asthenia, pain and the daily intake of antispastic lenitives were analysed at 6, 12, 24 and 60 months. Throughout this period all patients were treated with a water cure (31/day) and nocturnal decubitus in Trendelenburg's position (the foot of the bed is raised by 10 cm). Patients with primary or secondary kidney pathology, UTI and nephrolithiasis were excluded from the study. RESULTS: All the parameters showed a marked and steady improvement. At one year, over half the patients treated had improved, and at two years over two thirds only complained of marginal symptoms. CONCLUSIONS: Quali-quantitative and temporal values are reported in the light of which we can affirm that conservative treatment enables the patient to lead an almost normal life, as well as returning to work, with a reduced risk of complications.

[High-flux arteriovenous fistula at the anatomic snuffbox].

Based on 25 years of haemodialysis experience, the authors confirm the importance of arteriovenous fistula at the anatomic snuff-box by L-L anastomosis with vessel end-tie, and assert that, even using small vessels, through simple devices, it is possible to achieve high-flux vascular access, that can be employed also for high-efficiency treatments (HF, HDF). The advantages and the troubles of this vascular access are considered and also the reasons that lead to dropping this arterio-venous fistula too. The authors describe the surgical technique and the devices of the procedure, based on their case-reports of 131 arteriovenous fistulas at the anatomic snuff-box, immediately working in 95% of the cases and compatible with high-flux blood in 67% of cases. Fine adventitial bridle resection is very important, because this procedure allows us to rest the venous vessel wall on the top of the fistula; the ligature of all collateral vessels is very important too. The arteriovenous fistula at the anatomic snuff-box (L-L terminated, with anastomotic leak of 5 mm) is the most advisable vascular access for all the patients in whom we can plan the start of dialysis some months advance.

[Renal ptosis. Results of a national survey].

BACKGROUND: Renal ptosis is the caudal acquired displacement of one or both of the kidneys, with different degree and etiology, considered as a urological pathology because of its urodynamic changes and, in the last years, almost completely neglected. METHODS: The aim of the work is to research a parenchymal involvement, through a close examination of our outpatient's record; compared with data from the literature on renal ptosis and with the results of a national questionnaire to specialists. RESULTS: The literature reports a largest incidence in females; in our cases, instead, the incidence is nearly the same. The 2nd degree ptosis is the most frequent, but, in females, bilateral ptosis is prevalent (77%). We agree with the literature about urinary symptoms; actually, the most of the patients shows urinary colics or lumbar pain. We also noticed UTI (62%), urinary lithiasis (26%) and pyelocalyceal ectasia (46%). A lot of patients suffer from microscopic hematuria (77%) and, in 12%, gross haematuria was noticed. Hypertension affects about an half of the patients (46%) and the proteinuria too (42%). Echography highlights a reduced cortex (12%), cysts (14%) and other changes (8%). GFR is decreased in 30% of cases, in different degree. The patients show different changes, according to their age. The results of the national questionnaire are also reported. CONCLUSIONS: In conclusion, considering the remarkable incidence and anatomical and functional changes, it is suggested to consider renal ptosis as a cause of chronic renal damage, also because it is included among the causes of obstructive nephropathy, which according to some researchers, can cause severe glomerular and tubular-interstitial changes, triggered off by a short urinary stasis and evident in the contralateral kidney too.

[Protozoan infection (Blastocystis hominis) concomitant with Pseudomonas sp. peritonitis in continuous ambulatory peritoneal dialysis (CAPD)].

Case-report of protozoal infection (Blastocystis bominis) during Pseudomonas peritonitis in male patient with intestinal diverticulosis on continuous ambulatory peritoneal dialysis (CAPD) treatment for chronic renal failure (CRF). Microscopic morphology and cultural characteristics are summarized from current literature. Photographic images in phase contrast from fresh-observation of faeces and peritoneal fluid are reported. Although other Protozoa (e.g. Acanthamoeba free-living) have already been found in dialysis fluid, this is the first case, referred in literature, of Blastocystis bominis infection in CAPD patients. Some pathogenetic hypothesis are done involving Blastocystis bominis in peritoneal infection, especially in immunodepressed patients like dialysed ones. Although many chemotherapeutics are provided for this protozoiasis during enteritis, in our case no supplement was required except specific antibiotic therapy for Pseudomonas infection. Symbion or pathogen? Is now-a-day the question which troubles parasitologists. Systemic research of Protozoa in dialysed patients is anyhow advisable.

In conclusion, considering that the incidence and the anatomic and functional changes are remarkable, we think it opportune to take renal ptosis into account as a cause of chronic renal damage, also because it is included among the causes of obstructive nephrophaty, which according to some researches, can cause severe glomerular and tubular-intestinal changes, triggered off by a short urinary stasis and evident in the controlateral kidney too.

[Utilization of an electronic archive in the organization of clinical data from patients at a dialysis center].

Today multiple programs allow storing of clinical data not yet satisfactory to practical management of nephrological patients. This work presents an electronic case history realized for nephrologic hospitalized or out patients, both in dialysis and in maintenance treatment, processed on a data-base (Fourth Dimension of Apple- Macintosh) which uses a "fourth generation" programming language and allows a personal or a multiple choice and a full data protection. As well as the personal or a multiple choice and a full data protection. As well as the storage of data about a single patient, the program allows an evaluation with correlations of data about all the patients. Fourth Dimension allows any sort of printing too, reports, accounts, cards, requests for tests, prescriptions and labels, with any kind of information coming from different files, which allows: a) to program pharmacological and dialytical treatments; b) to organize the employment of kidney machines according to the real needs and the availability; c) to balance weekly times, improving the working program; d) to plan prospects of expenses for the following year.
