This survey includes 25 children with Wilms' tumor undergoing high-dose chemotherapy associated with autologous bone marrow transplantation (ABMT) in the period June 1984-December 1991 and enrolled in the European Bone Marrow Transplantation Registry for Solid Tumors. At diagnosis, 12 children presented stage IV disease, 5 stage III, 3 stage II, and 5 stage I. Before ABMT, 21 children had 1 to 4 relapses (median 1); 13 achieved a second or subsequent complete remission (CR), four stage IV children failed to respond to first line treatment and achieved either CR (3 patients), or partial remission (PR) after second line therapy. At high-dose chemotherapy, 17 children were in CR and 8 had measurable disease. Seven different high-dose regimens were administered, even if 20 children received melphalan mostly associated with vincristine and 8 involved field radiotherapy. Three children died early of pneumonitis; 2 developed an acute transient renal failure, 1 a chronic renal failure. Out of the 8 children with target disease at graft, 2 died of toxicity, 5 achieved CR, 1 obtained PR, and only 1 is presently alive in CCR at 39 months after ABMT. Of the 17 children grafted in CR, 8 are alive event-free at 14-90 months (median 34) from ABMT; 7 relapsed at 3-23 months (median 7 months); 1 died of toxicity and 1 was lost to follow-up in CR at 12 months. A salvage attempt with high-dose chemotherapy in children with resistant or poor prognosis recurrent Wilms' tumor seems to be justified. An international cooperative protocol taking into account the increased risk of lung and renal toxicity is necessary.

We report a 70-year-old man who had a sudden onset of right hemiparesis and mutism. The lower extremity was more involved than the upper one. He had a long history of diabetes and chronic renal failure for which hemodialysis was necessary. On August 30, 1990, he had an sudden onset of right hemiparesis and mutism. Neurological examination revealed awake but mute in no acute distress. He could only respond to very simple commands such as opening his mouth or protruding his tongue. He did not appear to understand more difficult questions. In addition, he could not answer verbally. He was totally mute. Cranial nerves appeared intact except for slight right central facial paresis and severe diabetic retinopathy. He had complete paralysis of his right leg and a moderate weakness in his right upper extremity. Deep reflexes were diminished in both upper extremities and absent in the lower limbs. Frotal signs such as grasp and snout reflexes were present. Cranial CT scans revealed an ill-defined low density area in the left parasagittal subcortical area and a part of the anterior cerebral artery territory. The supplementary motor area appeared at least in part to be involved. He was treated with glycerol and other supportive cares, however, his clinical course was complicated by pneumonia, heart failure, septicemia, and he expired two months after his stroke. The patient was discussed in a neurological CPC, and the chief discussant arrived at a conclusion that he had an artery-to-artery embolism at the internal carotid bifurcation resulting in the cerebral infarction mainly in the territory of the anterior cerebral artery.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical efficacy of fluconazole on fungal infections was evaluated. Fluconazole was administrated orally or intravenously to 16 cases with fungal infections (chronic renal failure 4, congestive heart failure 2, cerebral infarction 2, etc). All cases were suspected of mycosis. The details of those administrated were 16 cases of pneumonia 3 cases, fungemia 9 cases (suspected 7 cases) and urinary tract infection 3 cases. Clinical efficacy rate was 71.4%. Side-effects were observed in only 1 case, and this consisted of transient increase of leukocytes and thrombocytes. Fluconazole is considered to be a potent, safe antifungal agent for the treatment of suspected fungal infection during intravenous hyperalimentation.

During the final phases of chronic renal disease, inpatient care comprises an enormous share of morbidity and direct medical costs. Using an attributable risk methodology, this study calculated inpatient resource utilization and associated costs for chronic renal failure (CRF) and ESRD. A national hospital survey was used to identify the 348,962 hospitalizations for patients with renal failure in 1991. Among persons under the age of 65, pre-ESRD CRF patients had the same number of hospitalizations (nearly 75,000) as ESRD patients. Age-adjusted relative risk calculations indicate that patients with renal failure experience greater inpatient morbidity compared with other populations with chronic, progressive diseases. For example, compared with persons with diabetes, ischemic heart disease, hypertension, and emphysema, renal patients were at significantly higher risk of hospitalization for congestive heart failure, pneumonia, sepsis, electrolyte disorders, and gastrointestinal hemorrhage. Overall, renal failure patients were ten times more likely to be hospitalized (relative risk, 10.0; 95% confidence interval, 10.00 to 10.04) and, on average, were hospitalized nearly 1 day longer (P < 0.01) compared with the non-renal failure population in 1991. As a result, the economic consequences of inpatient care for the treatment of renal failure were enormous. In 1991, 222,827 hospitalizations, 1.5 million days of inpatient care, and $2.2 billion were attributable to renal failure. Further studies that examine other components of direct medical costs (e.g., long-term care, outpatient care, and pharmaceuticals) as well as indirect costs associated with the treatment and care of renal failure patients are warranted.

Renal transplantation was performed on 6 cats with chronic renal failure. Clinical signs and the blood chemistry findings (BUN, Cr, IP) improved one week after renal transplantation. Renal anemia also improved 3-4 weeks after surgery. Two cases had the same complications, hydronephrosis and hydroureter within 1 or 2 weeks of surgery, evidenced by marked elevations of BUN and Cr, suggesting that ureteral obstruction at the site of ureterocystostomy is the main complication of renal transplantation in cats. As a new resolution for this problem, we transplanted the ureter with the intact ureteral opening of the bladder from the donor in the remaining 4 cats. Ureteral obstruction was not observed in them, thus the procedure was considered to be useful for avoiding this complication. Two cats died of pneumonia and other complications within 3 months. There were no acute rejections or side effects from the immunosuppressant during the observation period in the remaining four cats.

Clinical data and outcomes of 18 patients, aged 80 or older, on continuous ambulatory peritoneal dialysis (CAPD) during the last five years were reviewed. There were 12 males and 6 females, with a mean age of 85 (range 82-91 years) and median duration on CAPD of 31.5 months (range 2-58 months). End-stage renal disease was caused by nephrosclerosis in 9, diabetes mellitus and light chain disease in 2 each, and chronic glomerulonephritis, membranous nephropathy, and IgA nephropathy in 1 each, with the cause unknown in yet another 2 patients. Hypertension and angina were the commonest comorbid conditions observed. Peritonitis episodes occurred one per 10.8 patient-months, and necessitated catheter removal in 7 patients and reinsertion in 6 of them. Fourteen episodes of exit-site infections were seen in 8 patients, 2 developed pericatheter leak, and 1 had tunnel infection. Nine patients are continuing CAPD successfully, with a median duration of 29 months (range 11-57 months). One patient was transferred to hemodialysis, and 8 died. The causes of death were peritonitis (3/8), cerebrovascular accident (2/8), pneumonia (1/8), and septicemia (1/8), with the cause not known in 1 patient. Our survival rate of 80% at three years is encouraging, and we advocate CAPD as a successful alternative treatment modality in octogenarians.

A case of repetitive hallucinations during treatment with a therapeutic dosage of triazolam (0.25 mg/day) and nitrazepam (5 mg/day) is presented. The patient suffered from acute pneumonia and chronic renal failure. Such non-psychotic symptoms as anxiety, tremor and depressed feeling were observed initially. However, after co-administration of erythromycin (600 mg/day), visual hallucinations and abnormal bodily sensations developed repeatedly after each administration of triazolam or nitrazepam. This report suggests that benzodiazepine hypnotics even at a therapeutic dosage with co-administration of erythromycin causes serious psychotic symptoms in vulnerable patients with physical complications.

Despite the fact that the epidemiology of community-acquired pneumonia and nosocomial Legionella infection is well known, there are no specific reports dealing with severe cases of Legionella pneumophila pneumonia admitted to intensive care units. We undertook a prospective study upon 84 patients with a reliable diagnosis of L. pneumophila pneumonia that required ICU admission. The study assessed the prognostic factors, clinical, radiological and outcome variables of both nosocomial (n = 33) and community-acquired (n = 51) cases of L. pneumophila pneumonia. The following variables were more common in nosocomial acquired as compared to community-acquired Legionella pneumonia: Chronic obstructive pulmonary disease (COPD) (64 versus 41%), cardiac disease (39 versus 10%), chronic renal failure (21 versus 4%), alcoholism (54 versus 18%), septic shock (33 versus 16%), and unilateral chest X-ray involvement (61 versus 39%). The crude mortality rate in this study was 30% (25 of 84) with no differences when comparing mortality between nosocomial (9, 27%) to community-acquired (16, 31%) types. The univariate analysis showed that cardiac disease, diabetes mellitus, creatinine > or = 1.8 mg/dl, septic shock, chest X-ray extension, mechanical ventilation, hyponatremia < or = 136 mEq/L, PACO2/FIO2 < 130, and blood urea levels > or = 30 mg/dl were factors related to poor outcome. On the other hand, the following two variables were related to better outcome: adequate treatment for Legionella and pneumonia improvement. The logistic regression analysis demonstrated that APACHE II score > 15 at admission (RR: 11.5; 95% CI 1.75 to 76.1; p = 0.025), and serum Na levels < or = 136 (RR: 21.3; 95% CI 1.11 to 408; p = 0.023), were the only independent factors related to death. On the other hand, improving pneumonia is associated with better outcome in Legionnaires' disease than for patients not having improving pneumonia (RR: 0.019; 95% CI: 0.036 to 0.106; p < 0.0001). A better understanding of the prognostic factors in cases of severe Legionella pneumonia will optimize our therapeutic approach in this disease and help to decrease both its mortality and morbidity rates.

Eighteen cases of pneumonia developed during an outbreak of adenovirus infection in a chronic psychiatric care facility. The six patients most severely affected were admitted to the intensive care unit (ICU) at our institution. Four of these patients developed septic shock. We report the presentation, disease progression, and response to treatment of these patients. Clinical features consisted of high fever, nonproductive cough, and dense lower lobe infiltrates. Laboratory abnormalities included transient fall in white blood cell and platelet counts, and elevations of transaminases, lactate dehydrogenase (LDH), and creatinine phosphokinase (CPK). Five patients were intubated for hypoxemia and four developed the acute respiratory distress syndrome (ARDS) and septic shock (mean cardiac output, 14.1 +/- 1.3 L/min; cardiac index, 6.4 +/- 0.4 L/min/min2; systemic vascular resistance, 326 +/- 107 dyne cm/s2). All patients recovered and were discharged back to the chronic care facility except for one patient with chronic renal failure who died 2 mo after admission. Adenovirus (serotype 35) was isolated from the respiratory secretions of five patients and antibody titers increased 6-fold in the other. These patients constitute the largest series of patients with ARDS and septic shock caused by adenovirus pneumonia and the first outbreak of multiple cases of adenovirus pneumonia in immunocompetent civilian adults occurring from a single source.

End-stage renal disease (ESRD) is the stage of renal failure at which an individual requires dialysis therapy or a renal transplant to survive. The prevalence of ESRD is disproportionately higher among patients aged > 65 years, and the average age of new ESRD patients is continually rising in the US Medicare population. Medication management in this population is challenging because of the combination of multiple comorbid disease states, a plethora of medications and the added dimension of dialysis therapy, as well as pharmacokinetic and pharmacodynamic changes attributable to the aging process. Cardiovascular disorders such as hypertension, coronary artery disease, congestive heart failure and arrhythmias are common in elderly patients with ESRD, and account for most of the deaths in this population. Constipation is common in patients aged > 65 years, and its incidence is even higher among those receiving dialysis. Pain management is of particular concern because elderly dialysis patients are frequently prescribed inappropriate pain relief regimens. Many healthcare practitioners do not realise that patients with uraemia are at a higher risk of bleeding caused by nonsteroidal anti-inflammatory drugs than are patients with normal renal function. In addition, most practitioners do not appreciate that virtually all opioids (narcotics) and their active metabolites accumulate in patients with renal failure, leading to an increased risk of narcosis. Infectious complications are frequent in the ESRD population, with dialysis access infections and pneumonia being the 2 most common infections seen in hospitalized patients receiving dialysis treatment. The establishment of vaccination programmes for the prevention of hepatitis B, influenza and pneumococcal infections is important because of the increased risk of these disease in this population. Unfortunately, these high-risk patients display, in general, a decreased immunogenic response to vaccinations. This article addresses some of the practical issues that surround the medication management or prevention of these particular diseases in elderly patients undergoing haemodialysis. Specifically, we discuss the pharmacokinetic and pharmacodynamic changes that occur with specific medications in such patients. Drug dialysability is also discussed.
