The influence of postural changes on renal function was determined in 13 patients with nephroptosis and in 5 normal subjects by measuring GFR in the erect and supine positions. The results indicate that GFR was reduced in the erect position in 10 of 13 patients with either unilateral or bilateral nephroptosis whereas GFR was increased in the erect position in 4 of 5 patients without renal disease. One patient with bilateral nephroptosis and renovascular hypertension was studied before and after surgical correction of his disease. These observations indicate that patients with nephroptosis may have significant reductions in renal function when they assume an upright position, and suggest that GFR measurements in the supine and erect position in patients with nephroptosis can be helpful in evaluating this disease. 相似文献

Tuberculous knee joint lesion in children is the most common form of articular pathology. The high sociomedical significance of this disease in modern society is determined by not only its prevalence, but also economic losses caused by high disability rates in children. The purpose of the study was to determine the possibilities and place of a comprehensive radiation study in the diagnosis of tuberculous gonitis in children. Sixty patients aged 10 months to 18 years were examined. Clinical studies were comprehensively assessed, by taking into account the collected history data and orhthopedic and laboratory findings. Surgery was made in 26 children. All the patients underwent mutiprojection X-ray study, knee joint ultrasound study being made in 48 patients. Knee joint X-ray study was performed on Siregraph (Siemens) apparatuses. Real-time ultrasonography was conducted on Aloka SSD-1100 and Aloka--3500+ apparatuses, by employing a 7.5-MHz linear transducer. According to P.G. Kornev (1971), three phases were identified in the course of tuberculous gonitis. These included prearthritic (the development of primary ostitis); arthritic (articular cartilage destruction, followed by the development of secondary arthritis; and postarthritic (sequels of prior tuberculous osteomyelitis) phases. Analysis indicated that the use of the routine X-ray study in combination with ultrasound scanning in the diagnosis of tuberculous gonitis in children yielded more adequate information on tissue and knee joint structural changes and made it possible to define further policy treatment and to predict the outcomes of the disease. 相似文献

Short- and long-term effectiveness of laparoscopic nephropexy was evaluated in patients with symptomatic nephroptosis especially quality of life of the patients and repositioning of the ptotic kidney. In 87 patients with symptomatic nephroptosis laparoscopic nephropexy was performed from 1994 to 2003. In 86 patients trans-abdominal approach was used and retroperitoneal in one patient. Visual pain scale was used for pain evaluation before surgery and six month after surgery. At the same period creatinine serum concentration, urine examination, i.v. urography and ultrasound in supine and erect position was made. There was statistical significant decrease of pain from 6.5 +/- 1.055 (SD) to 2.4 +/- 1.577 (SD) (p = 0.000), according to visual scale, and decrease of urinary tract infections (p = 0.000) in patients after laparoscopic nephropexy. Average operative time was 45.9 +/- 8 (SD) min., and hospital stay 3.4 +/- 0.7 (SD) days. Reposition of the kidney was successful in 70 of 80 patients. Laparoscopic nephropexy importantly improved the quality of life in patients with symptomatic nephroptosis. Surgical procedure was safe and successful in most of the patients. 相似文献

Renal artery aneurysms were diagnosed in 11 patients (9 boys) aged 1 to 14. The examinations were carried out for vasorenal hypertension in 4 cases, for bladder-ureter reflux, hematuria, nephroptosis in 4, ureterohydronephrosis in 2 cases, and for interstitial nephritis. Aneurysms of the major trunk of the renal artery, mostly oval-shaped, 11 x 14 to 25 x 28 mm in size, were detected in 4 patients, intrarenal aneurysms 2 x 3 to 5 x 6 mm in size in 7 cases. The share of aneurysms among uronephrologic conditions in children was found to be 1.54%, among vasorenal hypertension cases, 4.3%. Vasorenal hypertension is the main optional sign of aneurysms of the main trunk of the renal artery, whereas for intrarenal aneurysms such sign is hematuria. 相似文献

The mental development level of the children living in the territories polluted by the radioactive nuclide as the result of Cheernobil power plant damage, exposed to the prenatal irradiation, evacuated from the alienation zone, born from parents-liquidators (1st generation of the irradiated people) was evaluated. 177 children were examinated. The control group included 34 children not exposed to the radiation. The complex of psychometric methods--"D. Wexler children's intellectual test"--for 3-6-year-old children in the translation and adaptation of A.U. Panasyuk was applied for evaluating the intellect rate. In the structure of the observed groups the pathology diseases of nervous system, of digestion organs and the congenital anomalies prevailed. Clinical and instrumental investigation showed no differences in the neurology status between the observed and the control groups. It was proved that the intellect of the children exposed to the radiation corresponds the age standards. However, intellectual development of the children irradiated in the prenatal period and children evacuated from the 2nd zone of radioactive pollution (or living there) has a tendency to its decreasing. The determining role of social, of economic and of biologic factors (the parents' education, the region of living, the birth weight) in the intellect development was indicated. 相似文献

Orthostatic hypertension (HTO) is a well-known clinical entity and is sometimes associated with excessive renal mobility. During nephroptosis, dynamic renal scintigraphy (SRD) allows the identification of scintigraphic abnormalities suggestive of HTO guiding therapeutic by nephropexy. The authors report a case of HTO combined with a mobile right kidney, treated favourably by nephropexy and whose diagnosis was suggested by DTPA-Tc99m dynamic renal scintigraphy results. 相似文献

A total of 1205 primary school children were examined for cystic echinococcosis in five villages of Manisa, Turkey, to evaluate the efficacy of diagnostic methods of this infection in community-based screening surveys. Six hundred and thirty children from three villages, examined by a portable ultrasound scanner, chest microfilm and serological methods (ELISA, indirect hemagglutination) in our previous study, were designated as Study Group 1; and 575 children, from two adjacent villages, examined by ultrasonography alone in the present study, were designated as Study Group 2. In Study Group 1, hepatic cystic echinococcosis was detected in two cases (0.3%) by ultrasonography, while 43 (8.9%) and 49 (10.1%) cases were found to be positive for cystic echinococcosis by ELISA and indirect hemagglutination, respectively. Three of 575 children (0.5%) were diagnosed with cystic echinococcosis (two hepatic and one renal involvement) by ultrasonography alone in Study Group 2; and lung lesions were later detected in both cases with liver involvement by chest radiography.
Our results suggested that serological tests may be beneficial in suspected cases for confirmation and differential diagnosis, but have some drawbacks, such as discrepancy in results and high false seropositivity rates. Chest microfilm is not easy in field studies and exposure to X-ray is undesirable. As a reliable, simple, inexpensive and rapid technique, ultrasonography alone is recommended to be used in community-based screening surveys for cystic echinococcosis with confirmatory tests for suspected cases found during the screening program. 相似文献

During the last decade, our knowledge of the mechanisms by which children respond to exposures to physical and chemical agents present in the environment, has significantly increased. Results of recent projects and programmes focused on children's health underline a specific vulnerability of children to environmental genotoxicants. Environmental research on children predominantly investigates the health effects of air pollution while effects from radiation exposure deserve more attention. The main sources of knowledge on genome damage of children exposed to radiation are studies performed after the Chernobyl nuclear plant accident in 1986. The present review presents and discusses data collected from papers analyzing genome damage in children environmentally exposed to ionizing radiation. Overall, the evidence from the studies conducted following the Chernobyl accident, nuclear tests, environmental radiation pollution and indoor accidental contamination reveals consistently increased chromosome aberration and micronuclei frequency in exposed than in referent children. Future research in this area should be focused on studies providing information on: (a) effects on children caused by low doses of radiation; (b) effects on children from combined exposure to low doses of radiation and chemical agents from food, water and air; and (c) specific effects from exposure during early childhood (radioisotopes from water, radon in homes). Special consideration should also be given to a possible impact of a radiochemical environment to the development of an adaptive response for genomic damage. Interactive databases should be developed to provide integration of cytogenetic data, childhood cancer registry data and information on environmental contamination. The overall aim is to introduce timely and efficient preventive measures, by means of a better knowledge of the early and delayed health effects in children resulting from radiation exposure. 相似文献

OBJECTIVE--To assess the ability of ultrasonography to identify reflux nephropathy in children after urinary tract infection. DESIGN--Ten experienced radiologists performed a total of 240 ultrasonographic examinations of kidneys in a one day study. The examiners were unaware of the results of previous radiological and clinical examinations and of the proportions of normal and abnormal kidneys. Urography was used as method of reference, supported by static renal scintigraphy (dimercaptosuccinic acid labelled with technetium-99m) in half of the cases. SETTING--Outpatient radiology department. SUBJECTS--25 children aged 2-16 years (20 kidneys with and 30 kidneys without renal scarring). MAIN OUTCOME MEASURES--Renal scarring. Overall size and length of kidneys. Sensitivity and specificity including receiver operator characteristics and variation between observers. RESULTS--With renal scarring as the diagnostic criterion and including cases classified as abnormal, probably abnormal, and uncertain the sensitivity of ultrasonography was 54% (specificity 80%). Addition of reduced renal size as a diagnostic criterion increased the sensitivity to 64% (specificity 79%). There were, however, wide variations between observers, with sensitivity ranging between 40% and 90% (specificity 94% to 65%). CONCLUSIONS--Because of its low sensitivity and specificity and poor agreement between observers, ultrasonography cannot be generally recommended for the detection of reflux nephropathy after urinary tract infection in children. 相似文献

Ceftazidime (Fortum-Glaxo) was administrated to 19 children with urinary tract infections and to 21 children with pneumonia. Clinical symptoms of the infections resolved in 17 children (89%) with the urinary tract infections treated with ceftazidime within 4 days. The remaining children (11%) recovered after 7 days of therapy. Clinical symptoms of pneumonia resolved in 19 children (90%) within 7 days of the treatment. A significant improvement was achieved in the remaining 2 children after 10 days of the treatment. 相似文献

In the paper providing the data available in the literature and many years' experience gained by the Department of the Moscow Regional Clinical Research Institute, the authors describe the potentialities of the currently available radiation techniques in the diagnosis of surgical endocrine diseases. The incidence of various organ dysfunctions is presented. The authors also consider the introscopic symptoms of various endocrinopathies and outline the common specific features of the ultrasound, computed tomographic, and magnetic resonance imaging pattern of individual masses (including adipose tissue cysts and tumors). Emphasis is laid on the leading role of ultrasonography (USG) in the diagnosis of thyroid and parathyroid diseases and on the priorities of computed tomography (CT) and magnetic resonance imaging (MRI) in visualIzing the abnormal thymus, mediastinally ectopic glands, and pituitary tumors. The capacities of each technique in the diagnosis of endocrine space lesions of the pancreas and adrenals are defined. The increase in the frequency of endocrine abnormalities accidentally identified at USG, CT, and MRI, which is noted in the paper, fosters the development of new trends in endocrinology and points to the need for screening surveys (particularly patients who live in poor environmental areas). 相似文献

Epidemiological studies have found that children living around Chernobyl have rates of respiratory tract illness that are higher than those seen in the area before the Chernobyl accident. The present study investigates the possible effects of radiation exposure on the composition of peripheral blood lymphocyte subsets in children living around Chernobyl. Two hundred nineteen healthy children and children suffering from recurrent respiratory diseases aged 6-14 years who received both low doses of radiation to the whole body from (137)Cs and various doses of radiation to the thyroid from (131)I as fallout from the accident were assessed 5 (1991) and 8-10 years (1994-1996) after the accident. A total of 148 healthy children and children suffering from recurrent respiratory diseases living in noncontaminated areas were also evaluated as controls. Children with recurrent respiratory diseases who lived around Chernobyl had a significantly lower percentage of T cells and a higher percentage of NK cells compared to control children with recurrent respiratory diseases during the study period. In contrast to the findings in 1991, a significant decrease in the percentage of helper-inducer cells was observed in children with recurrent respiratory diseases in 1994-1996. In contrast to 1991, there is a positive correlation between the percentage of helper-inducer cells, the helper-inducer/cytotoxic-suppressor cell ratio, and the dose of radiation to the thyroid of healthy children from (131)I in 1994-1996. There was a positive correlation between the dose of radiation to the thyroid from (131)I and the percentage of helper-inducer cells in children with recurrent respiratory diseases 5 years (1991) after the accident. Further, the dose of radiation to the thyroid from (131)I correlated negatively with the percentage of T and B cells and positively with the percentage of NK cells in children with recurrent respiratory diseases 8-10 years (1994-1996) after the accident. These results raise the possibility that long-term exposure to low doses of (137)Cs may have altered the composition of the T-cell subsets and NK cells in children with recurrent respiratory diseases. The differences in the composition of the peripheral blood lymphocyte subsets between healthy children and those with recurrent respiratory diseases may be attributed to long-term low-dose exposure of the whole body to radiation from (137)Cs and exposure of the thyroid to radiation from (131)I subsequent to the Chernobyl accident. 相似文献

Background
Lung ultrasonography has been advocated in diagnosing pediatric community-acquired pneumonia. However, its function in identifying necrotizing pneumonia, a complication, has not been explored. This study investigated the value of lung ultrasonography in diagnosing pediatric necrotizing pneumonia and its role in predicting clinical outcomes.Methods
We retrospectively reviewed 236 children with community-acquired pneumonia who were evaluated using lung ultrasonography within 2–3 days after admission. The ultrasonographic features assessed included lung perfusion, the presence of hypoechoic lesions, and the amount of pleural effusion. Chest computed tomography was also performed in 96 patients as clinically indicated. Detailed records of clinical information were obtained.Results
Our results showed a high correlation between the degree of impaired perfusion in ultrasonography and the severity of necrosis in computed tomography (r = 0.704). The degree of impaired perfusion can favorably be used to predict massive necrosis in computed tomography (area under the receiver operating characteristic curve, 0.908). The characteristics of impaired perfusion and hypoechoic lesions in ultrasonography were associated with an increased risk of pneumatocele formation (odds ratio (OR), 10.11; 95% CI, 2.95–34.64) and the subsequent requirement for surgical lung resection (OR, 8.28; 95% CI, 1.86–36.93). Furthermore, a longer hospital stay would be expected if moderate-to-massive pleural effusion was observed in addition to impaired perfusion in ultrasonography (OR, 3.08; 95% CI, 1.15–8.29).Conclusion
Lung ultrasonography is favorably correlated with chest computed tomography in the diagnosis of necrotizing pneumonia, especially regarding massive necrosis of the lung. Because it is a simple and reliable imaging tool that is valuable in predicting clinical outcomes, we suggest that ultrasonography be applied as a surrogate for computed tomography for the early detection of severe necrotizing pneumonia in children. 相似文献14.

Somatic and genetic effects at children who have undergone the influence of ionizing radiation during in utero development and at the subsequent stages ontogenesis are investigated, in view of dozes of the general irradiation and equivalent dozes of an irradiation of red bone brain. 1144 children were examined: 1st group consisted of children who have been born from women pregnant at the moment of failure, evacuated from Pripyat; 2nd group included children who have been born from women pregnant at the moment of failure, stayed to live in a zone of the strict radiation control; 3rd group was the control group--children who have been born in 1986, living in safe region of the Ukraine according to radiation conditions. The presence of direct correlation link between quantity of small anomalies of the development and the total radiation dose of the fetus (R = 0.61, p < 0.002) and inverse link with fetus age at the moment of radiation factor effect (R = -0.53, p < 0.003) has been established. Significant correlation links between the total radiation dose and the level of children health (R = 0.45, p < 0.03); the equivalent radiation dose of the red bone marrow and the frequency of damages in the chromosomal apparatus of the somatic cells (1st group--R = 0.51, p < 0.02; 2nd group--R = 0.62, p < 0.002) have been revealed. 相似文献

Cystic cystitis is a separate form of urinary bladder inflammation, detected by cystoscopy in children with recurrent urinary infections. Cystoscopy is an invasive method, so the aim of this investigation was to determine the ultrasonographic characteristics of cystic cystitis and to assess the reliability of ultrasound in relation to cystoscopy in diagnosing cystic cystitis. The study included 115 girls with repeated urinary infections. Cystoscopy and ultrasonography was performed in all. According to the cystoscopic finding the subjects were divided into 4 groups. Lateral and posterior urinary bladder wall thickness was measured during ultrasonography. A statistically significant difference was found between all 4 groups, the method demonstrated a high degree of sensitivity (0.97) and specificity (0.91). Percentile calculations were determined for wall thickness. Ultrasonography can replace endoscopy in diagnosis and follow-up of cystic cystitis in children, with at least 50% fullness of the urinary bladder as a prerequisite. 相似文献

Gastric and intestinal scintigraphy in the complex diagnosis of small bowel obstruction 总被引:1,自引:0,他引:1
Kudriashova NE Ermolov AS Pakhomova GV Selina IE Skvortsova AV 《Vestnik rentgenologii i radiologii》2006,(5):22-29
An algorithm has been developed for radiation diagnosis of small bowel obstruction, which involves abdominal X-ray and ultrasound studies at the first stage and radionuclide evaluation of gastrointestinal transit, by using 100-150 ml of aqueous 99mTc-technefite or 99mTc-bromeside solution in a dose of 50-100 MBq (radiation load 0.7-1.4 MeV) per os. The sensitivity, specificity, and diagnostic efficiency of the whole radiation diagnostic complex and each procedure separately were determined by the results of examination in 180 patients with suspected small bowel obstruction, of whom 104 patients were operated on, but obstruction ceased during medical treatment. Inclusion of the radionuclide technique into the diagnostic complex involving plain radiography and ultrasonography was shown to enhance diagnostic efficiency up to 97-98%. 相似文献

OBJECTIVES--To assess whether ultrasonography alone is adequate for routine screening of childhood urinary infection, whether clinical features determine the need for further investigations, and which investigations are most appropriate. DESIGN--Prospective survey of children with proved urinary infection and a preinvestigation record of clinical features. Ultrasonography and intravenous urography were routine, with choice of further studies determined by ultrasonographic findings. SETTING--A children''s hospital and two district general hospitals in Mersey region. MAIN OUTCOME MEASURES--Sensitivity and specificity of ultrasonography both generally and in relation to clinical features. Accuracy of intravenous urography compared with radioisotope examinations. RESULTS--Specificity of ultrasonography was good (99% (95% confidence interval 96% to 100%)) but sensitivity modest (43% (32% to 55%)), principally with respect to detecting vesicoureteric reflux and renal scarring. Among older children (aged 2-10 years) with positive ultrasound results and fever or vomiting the sensitivity in detecting reflux (with and without renal scarring) was 78% (62% to 89%) and the specificity 69% (60% to 78%); in detecting renal scarring (with and without reflux) the sensitivity was 100% (80% to 100%) and specificity 65% (56% to 74%). Renal scarring and obstructive uropathies were better assessed by radioisotope examinations than by intravenous urography. CONCLUSIONS--Ultrasonography alone is inadequate for routine screening of childhood urinary infection. Though further investigations remain advisable in infants, in older children they can be restricted to a minority who have positive ultrasound examinations or have had fever or vomiting. Radioisotope examinations largely eliminate the need for intravenous urography. 相似文献

ObjectivesTo compare ultrasonography and abdominal radiography with intravenous urography in the investigation of urinary tract infection in men.DesignProspective study in two hospital departments. Radiological procedures and urological assessments performed on different days by different cliniciansSettingDistrict general hospital.ParticipantsConsecutive series of men (n=114) referred to the department of urology for investigation of proved urinary tract infection.InterventionsUltrasonography and intravenous urography of renal tract and assessment of urinary flow rate. Clinical assessment, cystoscopy, urodynamic studies, and transrectal ultrasonography with biopsy.ResultsImportant abnormalities were seen in 53 of 100 fully evaluated patients, the most common being a poorly emptying bladder (34). The combination of plain radiographs of kidneys, ureter, and bladder and ultrasonography detected more abnormalities than intravenous urography alone. No important abnormality was missed by this combination (sensitivity 100% and specificity 93%).ConclusionsUltrasonography with abdominal radiography is as accurate as intravenous urography in detecting important urological abnormalities in men presenting with urinary tract infection. This combination is safer than intravenous urography and should be the initial investigation for such patients. Additional determination of urinary flow rate is useful for the assessment of an incompletely emptying bladder.
What is already known on this topic
Ultrasonography alone is the primary investigation of choice for urinary tract infection in children and womenUltrasonography has limited sensitivity for renal stones and poor sensitivity for ureteric stonesUrinary infection is less common in men than women and the risk factors are differentWhat this study adds
Ultrasonography is as effective as intravenous urography in men with urinary tract infection only when it is combined with plain radiographyIn men aged over 50 an incompletely emptying bladder is the most common abnormalityIn such patients determination of urinary flow rate is particularly helpful 相似文献20.

Clinical researches in hyperthermia have recently expanded rapidly with the increase in our knowledge of the biological effects of heat on experimental systems. This article provides background information on the biological rationale and current status of technologies concerning thermometry and heating equipment for the application of hyperthermia to human cancer treatment. Much data has been accumulated recently in hyperthermia treatment with and without radiation to superficial tumours which are refractory to conventional treatments. In this paper the treatment results published recently have been surveyed. The complete responses of tumours treated by heat alone are in the range of 15 per cent as opposed to approximately 60 per cent for the combination of heat plus radiation. Clinical results so far published have demonstrated that local control is consistently better in the lesions treated with radiation plus heat than with radiation alone. The morbidity related to heat therapy is within tolerable limits. Several articles on the clinical results of deep-seated tumours treated by hyperthermia are reviewed. Problems to be solved in the application of heat to cancer therapy are discussed. 相似文献
