RESUMO
Autonomic nervous system is involved in body weight regulation. Gastrointestinal manifestations of systemic sclerosis (SSc) can influence patients nutritional status and facilitate the development of proteinenergy malnutrition. The aim of the study is to assess the nutritional status of SSc patients and to explore its possible correlation with autonomic dysfunction using heart rate variability (HRV). We enrolled 19 SSc subjects and 19 healthy subjects as controls. Body mass index (BMI) and body surface area (BSA) were collected and recorded in all patients. HRV was measured and the domains of low frequencies (LF, index of the sympathetic modulation) and high frequencies (HF, index of the parasympathetic modulation) were recorded. As assessed by the LF/HF RATIO, sympathovagal balance is altered in SSc patients because of increased sympathetic modulation and reduced parasympathetic activity. BMI positively correlates with LF (r=0.57; p less than 0.01) and LF/HF RATIO during daytime (r= 0.46; p less than 0.05). Similarly, BSA positively correlates with LF (r= 0.51; p less than 0.05), LF day time (r= 0.53; p less than 0.05) and LF/HF RATIO night time (r=-0.51; p less than 0.05). In SSc patients the autonomic dysfunction is characterized by increased sympathetic modulation. We observed a correlation between autonomic dysfunction and nutritional status in SSc patients.

The hypercoagulability of patients with nephrotic syndrome could be an important trigger for arterial and venous thrombotic events. Arterial thromboses are less frequent than venous thromboses and the most common locations are femoral arteries. The association of stroke and nephrotic syndrome is extremely rare. Here we report the case of a patient with stroke as first manifestation of nephrotic syndrome. Ischemic stroke can be the first manifestation of nephrotic syndrome and should be considered as a possible complication of the syndrome, when the commonest causes of ischemic stroke are excluded and especially in presence of pre-existing glomerular disease.

Idiopathic membranous glomerulonephritis is a frequent cause of nephrotic syndrome and may have a variable course, from spontaneous remission to progression on renal failure. The therapy is based on alternating steroids and chlorambucil or cyclophosphamide (Ponticelli protocol) for six months. In absence of complete or partial remission after protocol, cyclosporine, adrenocorticotropic hormone, mycophenolate mofetil, rituximab can be used for potential therapy. We report here the case of a woman with idiopathic membranous glomerulonephritis unresponsive to the Ponticelli regimen and treated with adrenocorticotropic hormone in association with azathioprine, showing a dramatic decrease of proteinuria and beneficial effects on lipid profile. After 36 months, no relapse of disease has occurred. Although larger cohorts of patients are needed to evaluate the long-term effects, adrenocorticotropic hormone plus azathioprine in association could be a possible therapeutic option for unresponsive idiopathic membranous glomerulonephritis.

Hypercalcemia is a rare metabolic disorder in course of B cell lymphoma. The mechanism of hypercalcemia in patients with malignancy may include the increased extrarenal production of vitamin D from tumoral cells or neighboring macrophages, i-PTH or PTHrP from tumoral cells. In this case we reported a 34 years old caucasian woman with acute renal failure and hypercalcemia as onset of splenic lymphoma in absence of abnormal levels of serum vitamin D and PTHrP. Because of dramatic recovery of renal function and hypercalcemia after splenectomy, we can speculate that main mechanism of hypercalcemia is related to vitamin D production from neighboring lymphoma macrophages.

Malnutrition is common in patients on hemodialysis and is a strong predicor of morbidity and mortality. Much progress has been made in recent years in identifying the causes and pathogenesis of malnutrition in hemodialysis patients as well as in recognizing the link between malnutrition and morbidity and mortality. Nevertheless, there is no consensus concerning its management. Conventional interventions such as nutritional counseling, oral nutritional supplements and intradialytic parenteral nutrition and novel preventive and therapeutic strategies such as appetite stimulants, growth hormone, androgenic anabolic steroids, and antiinflammatory drugs have been tested with contradictory and inconclusive results. Malnutrition still remains an important challenge for the nephrologist in the third millennium.

BACKGROUND/AIMS: This study was designed to evaluate the effectiveness of radical surgery for liver hydatid disease. MATERIALS AND METHODS: Hospital charts of 104 consecutive patients with liver hydatidosis observed in our unit during the period 1982-1994 were reviewed. A total of 121 cysts in 89 patients were treated surgically: with cystopericystectomy in 66 and liver resection in 23. RESULTS: The overall incidence of postoperative complications was 19%: 19.7% and 17.1% after cystoperi-cystectomy and liver resection respectively (p = 0.32). Overall postoperative mortality was 1%. Among the 72 patients available for follow-up, only one (1%) had a local recurrence of the disease. CONCLUSIONS: Results suggest the safety and efficacy of radical procedures in the surgical management of liver hydatid disease. Total cystopericystectomy is the treatment of choice but liver resection is justified in selected cases.

The authors describe various applications of scintigraphy with labeled leukocytes and its value in the diagnosis of gut diseases such as Crohn's disease, ulcerative colitis and related complications. Furthermore, the study of vascular prosthesis infection, cryptogenetic fever and abdominal sepsis, three cases of which are herein reported, is facilitated. The method, in conjunction with endoscopy and traditional radiology, revealed to be of great value in terms of sensitivity and specificity for the diagnosis of the aforementioned diseases. Therefore, the use of such method is encouraged in all those cases of abdominal sepsis of uncertain interpretation and in the evaluation of vascular prosthesis infection.
