The complicated and combined course of alimentary toxicoinfections are practically the main causes of all the lethal outcomes in these diseases. In this work the data on the recent progress in the rehydration therapy of acute enteric infections are presented. The authors established that combined forms constituted 15.3% and complicated ones constituted 2% of alimentary toxicoinfections. The results of the treatment of alimentary toxicoinfections combined with ischemic heart disease, hypertension and chronic alcoholism, as well as complicated by shock and pneumonia, are presented. The general principles of treatment in combined and complicated cases are the maintenance of the usual (under given conditions) volume of liquid for rehydration with the limitation of the rate of its introduction.

The application of lung transplantation to the pediatric population was a natural extension of the success realized in our adult transplantation program, which began in 1982. Twenty pediatric patients (age range 3 to 18 years) have had heart-lung (n = 11), double lung (n = 8), and single lung (n = 1) transplantation procedures. The causes of end-stage lung disease were primary pulmonary hypertension (n = 7), congenital heart disease (n = 5), cystic fibrosis (n = 4), pulmonary arteriovenous malformation (n = 2), graft-versus-host disease (n = 1), and desquamative interstitial pneumonitis (n = 1). Four (20%) patients had thoracic surgical procedures before the transplantation operation. The survival was 80% at a mean follow-up of 2 years. Immunosuppressive drugs included cyclosporine (n = 9) or FK 506 (n = 11) based therapy with azathioprine and steroids. Children were followed up by means of spirometry, transbronchial biopsy, and primed lymphocyte testing of bronchoalveolar lavage fluid. The mean number of treated episodes of rejection was 1.4 at 30 days, 0.5 at 30 to 90 days, and 1.4 at more than 90 days, and the first treated rejection episode occurred on average 28 days after the operation. Obliterative bronchiolitis developed in four (25%) of 16 patients surviving more than 100 days. Results of pulmonary function tests have remained good in almost all recipients. The greatest infectious risk was that of cytomegalovirus: one death and one case of pneumonia. Posttransplantation lymphoproliferative disease was diagnosed in two (12.5%) patients; both recovered. The most common complications were hypertension (25%) and postoperative bleeding (15%). Early results indicate that lung transplantation is a most promising therapy for children with severe vascular and parenchymal lung disease.

The new immunosuppressive agent FK506 was used with steroids to treat 22 pediatric patients who received living-related partial liver transplantation. Seventeen recipients survived and 5 died between one and 16 months after transplantation. Three of the 5 patients who died had required intensive care preoperatively. Autopsy findings showed no evidence of rejection. There was no episode of rejection that required retransplantation in any of the patients. Liver allograft dysfunction, which was suspected to be a rejection response, was encountered in 2 recipients with ABO-nonidentical but compatible grafts. However, their clinical and biochemical findings were ameliorated upon steroid pulse therapy or upon augmented FK506 administration without additional potent immunosuppressive agents. Steroid treatment has been discontinued in all surviving patients at 1-9 months after transplantation. Infectious complications encountered in 9 patients included 2 bacterial, 5 viral, and 2 fungal infections. One recipient died of fungal pneumonia. Abnormal increase of serum creatinine level was confined to the complicated patients. Hypertension was a temporary adverse reaction in the early postoperative period, and only one patient needed an antihypertensive drug at 2 months after transplantation. Acute pancreatitis with hyperamylasemia was observed in one patient who was treated successfully with reduction of FK506 administration. Tremor was observed in 8 patients, itching in 4, insomnia in 2, and vomiting in one. Hirsutism, gingival hypertrophy, and lymphoma were not observed. FK506 was highly effective in living-related partial liver transplantation not only in terms of immunosuppressive potential but also because it produced fewer adverse effects.

This study explored the prevalence of comorbid conditions in hospitalized patients with multiple sclerosis (MS) who were 65 years of age or older. Using 1989 data from the Quality of Care Medicare Provider Analysis and Review (MEDPAR) file, hospitalized MS patients were compared with respect to discharge diagnoses to an age- and sex-matched group of hospitalized patients without MS. As expected, the following discharge diagnoses were more common (P < 0.05) for MS patients: urinary tract infection, pneumonia, septicemia and cellulitus. In contrast, MS patients were less likely (P < 0.05) to have discharge diagnoses of acute myocardial infarction, heart failure, hypertension, angina pectoris, cerebrovascular disease, diabetes mellitus and chronic obstructive pulmonary disease. Possible explanations include under-reporting of certain comorbid conditions on discharge records of MS patients, a protective effect of MS or its treatment, reduced prevalence of risk factors, disproportionate mortality in younger MS patients with comorbidity and the benefits of medical surveillance.

Recently, renal osteodystrophy is a remarkable problem in patients on long-term hemodialysis (HD). In this retrospective study, we evaluated the perioperative management of 21 patients receiving orthopedic surgery between January 1990 and December 1992. These patients had been maintained on HD for an average of 8.6 years (range, 18 months-20 years). The primary causes of orthopedic surgery were amyloidosis, diabetic gangrene, rheumatoid arthritis and fractures. Laminectomy, replacement of arthropathy, osteosynthesis and amputation of the lower extremity were undertaken. General anesthesia was performed on six patients. Vecuronium was given to all of these patients. Isoflurane was used in 5 patients and sevoflurane in 1 patient. Regional anesthesia was used in 15 patients. During anesthesia, the average infusion rate of intravenous fluids was 2.7 ml.kg-1.h-1, and the intraoperative complications included hypertension in 16, hypotension in 12, arrhythmia in 4 and prolonged sedation in 2 patients. Postoperative complications included hyperkalemia in 2, pneumonia in 2, psychological disorder in 3, clotting fistula in 1 and delayed wound healing in 7 patients. One early death in a diabetic patient following amputation occurred on the 13th postoperative day. Preoperative HD was performed within 24 hours and postoperative HD within 72 hours of the operation. Nafamostat mesilate was used as an anticoagulant. Excessive removal of potassium must be avoided during preoperative HD to prevent arrhythmia. The well-managed elective patients gave a good result. However, extreme care in nutrition and infection control should be taken, especially in diabetic patients.

Small area variation analysis is a research tool used by health services researchers to describe how rates of health care use and events vary over well-defined geographic areas. Significant variation has been shown to exist in the rates of hospitalization for chronic obstructive lung disease, pneumonia, hypertension, and in surgical procedures, such as hysterectomy, cholecystectomy, and tonsillectomy. Potential sources of variation include differences in underlying morbidity, access to care, physician judgment, quality of care delivered, patient demand for services, and random variation. Small area variation studies have been used to determine if significant variation exists across geographic areas and to describe relationships between the observed variation and potential causal factors. Methodologic concerns include the definition of small areas, defining the at-risk population within each small area, sample size, case mix adjustments, and stability of rates over time. The use of small area analysis in primary care will require definition of appropriate small areas for ambulatory care, description of the variation in ambulatory events across small areas, development of appropriate measures for ambulatory case mix, and development of appropriate tools to measure the outcomes of ambulatory care.

The objective of this study was to describe the health problems of a group dementia patients on admission and during residence in a Dutch nursing home and to compare these with figures of patients of 75 years and over from general practice. In 890 nursing home patients suffering from dementia prevalence of health problems on admission and the incidence during the residence were classified by means of the ICHPPC-2-defined. The differences between men and women were studied as was the influence of the season on the incidence during the stay. Results were compared with figures of patients of seventy five year and over from the continuous morbidity registration (CMR) from 'Nijmegen'. The most frequently occurring health problems on admission were: varicose veins of legs, acquired deformation of the spine, presbyacusis, hypertension, arthrosis, COPD, cerebrovascular disorders, heart murmur, cataract and chronic ischemic heart disease. During the residence the following health problems were frequently diagnosed: urinary tract infection, side effect of medicine, constipation, pneumonia, pressure sore, feeding problem, contusion, heart failure, cold and conjunctivitis. There were clear differences between men and women. Especially the incidence of intercurrent diseases showed great differences from the patterns in general practice. Prevalence of health problems on admission to the nursing home home agreed mor with figures from general practice. Respiratory tract infections frequently occurred in winter and urinary tract infections, pressure sores and conjunctivitis seemed to occur more in the summer. Nursing home patients with dementia have a lot of chronic and intercurrent health problems. They differ clearly from patients in general practice.(ABSTRACT TRUNCATED AT 250 WORDS)

Non-resolved chronic pulmonary thromboembolism is a frequent cause of pulmonary hypertension. In long-standing disease hypertension is progressive due to intimal and medial changes in the perfused vessels. Non-resolution of thromboemboli is often associated with underlying coagulopathies; the presence of a lupus anticoagulant may pose a significant problem in the peri-operative management of these patients. Pulmonary thrombendarterectomy presents an efficient option of treatment which is feasible in the majority of patients. By means of pulmonary angiography and computed tomography operability is verified by the often difficult recognition of thromboembolic changes in the central pulmonary arteries. Patients with solely peripheral thromboembolic changes or primary pulmonary hypertension must be excluded. In presence of significant exertional dyspnea and/or pulmonary pressure elevation surgery is indicated. Mortality is high and mainly related to unrelieved pulmonary hypertension or pulmonary complications; pulmonary reperfusion edema, respiratory failure or pneumonia and sepsis. In all survivors the reduction of pulmonary hypertension is highly significant and persistent. Thromboembolic pulmonary hypertension may be treated curatively in most patients by thrombendarterectomy. Correct selection of surgical candidates is mandatory, and the patients should preferably be diagnosed and undergo surgery in an early stage of their disease.

Churg-Strauss syndrome (CSS) is a disease characterised by hypereosinophilia and systemic vasculitis occurring in patients with asthma and allergic rhinitis. In the course of CSS three phases may be distinguished. The prodromal phase, which may persist for many years, consists of allergic disease. The second phase is characterised by peripheral blood eosinophilia and eosinophilic tissue infiltrates that produce a clinical picture diagnosed as Loeffler's syndrome, chronic eosinophilic pneumonia or eosinophilic gastroenteritis. The third phase is dominated by systemic vasculitis in which skin, cardiovascular system, gastrointestinal tract and peripheral nervous system are frequently involved. Renal disease in CSS is less common and generally less severe than that classical polyarteritis nodosa and Wegener's granulomatosis. Genitourinary tract may be involved, too. In the postvaculitic phase, allergic rhinitis and asthma usually persist and clinical picture is characterised by the consequences of the vasculitic illness, most commonly in form of neuropathy and hypertension. The pathogenesis of CSS is unknown but its association with asthma and allergic rhinitis may indicate an abnormal immune reactivity. The recently reported association with antineutrophil cytoplasmic antibodies with antimyeloperoxidase specificity may suggest a their role in the pathogenesis of the disease. An important role may be played by eosinophils, too. The main therapy is that with corticosteroids, possibly in association with immunosuppressive drugs.

The authors present a case report of a 62-year old woman, with hypertension for many years. She suffered from weakness, anorexia and weight loss in the last 6 months. On admission, anemia, elevated ESR, haematuria, proteinuria and renal failure were present. Renal biopsy was compatible with chronic glomerulonephritis. The clinical picture and positivity for P-ANCA suggested systemic vasculitis. Later evidence of maxillary sinusitis and nasal mucosae ulcers as well as pneumonitis, although biopsy did not reveal granulomas, suggested the diagnosis of Wegener Vasculitis. Medicated with Cyclophosphamide and Prednisolone, for a year, with improvement. The authors make a brief discussion of the clinical criteria for classification of ANCA-associated systemic vasculitis.
