A thousand cases of consecutive radiographic examinations of the chest, consisting of postero-anterior and left lateral views, were reviewed.In seven cases (0.7 per cent) the lateral view revealed clinically significant lesions which were not seen on the postero-anterior view.In 30 cases (3 per cent) the lateral view demonstrated clinically significant added information permitting more definite diagnosis.Addition of the lateral view to the routine roentgen study of the chest gives a more thorough and complete examination at minimal expense and permits a more definite diagnosis in a significant number of cases. 相似文献

Although expert committees have questioned the usefulness of lateral radiologic views of the chest without specific indications, many physicians commonly order both posteroanterior and lateral views in assessing pediatric patients who have signs and symptoms of acute chest disease. To investigate the usefulness of lateral view in children, three experienced physicians independently reviewed and interpreted the posteroanterior view alone and the posteroanterior and lateral views for 179 children 1 to 10 years of age. The films were made between 1980 and 1982 at McMaster University Medical Centre, Hamilton, Ont. A high level of agreement was found between the interpretations based on the posteroanterior view alone and those based on both views. Addition of the lateral view did not improve agreement between the interpretations and the final hospital chart radiologic diagnosis in a clinically significant manner, nor did the lateral view improve the accuracy of localization of radiologic abnormalities. Obtaining a lateral view whenever radiologic examination of the chest is indicated but when specific indications are lacking is unlikely to prove useful to experienced physicians in diagnosing and managing acute pulmonary illness in children. 相似文献

In 74,000 obstetrical patients at Los Angeles County Hospital the incidence of acute appendicitis in pregnancy was 0.05 per cent. In a study of 36 cases of clinically diagnosed appendicitis in pregnancy between 1956 and 1960, it was shown that the fetal and maternal morbidity and mortality were decreased when a definite operative procedure was done early. The difficulty in diagnosis is increased by the necessary consideration of pyelonephritis and twisted ovarian cyst. Rupture of the appendix increased hazards to maternal and fetal survival. It was noted also that threatened premature labor may indicate a ruptured appendix. Emergency operation with the use of antibiotics in such cases was effective therapy. The incidence of premature delivery was proportionate to the delay in operating. If operation was performed in less than eight hours after admission to the hospital, there was no maternal or fetal loss. A delay greater than eight hours resulted in a 17 per cent fetal loss in premature delivery and 4 per cent fetal loss of infants at term. 相似文献

A program was carried out to test the value and feasibility of performing blood sugar screening tests in conjunction with a community-wide chest x-ray survey. A simple, rapid and inexpensive blood sugar screening test requiring only about two drops of blood from the finger tip was used. Among 14,681 persons who stated that they did not have diabetes, 191 or 1.3 per cent had "positive" results in screening tests. The number of persons referred to their physicians for diagnostic study because of the possibility of diabetes was reduced from 191 to 127 by means of a more specific secondary screening test. Diagnostic information with regard to 102 of the 127 persons referred to their physicians was supplied by the physicians. In 58 (0.40 per cent of the 14,681 participants) the diagnosis was diabetes-newly discovered as a result of referral by the survey.Some of the persons referred to their physicians because of suspicion of diabetes, while not then diabetic, might be considered prediabetic. The appearance of diabetes in this group during the year following the survey was therefore investigated. Glucose tolerance tests were performed for 32 of the diabetes suspects whose diagnosis immediately following the survey was either "not diabetic" or unknown. In 15 cases the glucose tolerance curves were indicative of diabetes, in seven cases questionable and in ten cases normal. The 58 persons diagnosed immediately after the survey plus the 15 found to have "diabetic" glucose tolerance curves a year later made a total of 73 newly discovered diabetics. This is a discovery rate of 0.50 per cent among the 14,681 participants in the survey. The success of this combined diabetes detection and chest x-ray survey suggests that other screening procedures should be studied to determine the desirability of adding them to similar community-wide case-finding programs. 相似文献

In a review of a series of 248 salivary gland tumors, seen over a 28-year period, all pathologic material was brought up to date by reclassification according to more recent criteria and nomenclature. In parotid tumors, a probable lowered recurrence rate and a definite decrease in incidence of permanent facial nerve paralysis was found in the more recent cases in which the "Y" incision was used, with identification of the seventh nerve as it leaves the stylomastoid foramen. The five-year recurrence rate for primary mixed tumor was 8.3 per cent, and in recurrent cases it was found to be 18.1 per cent. Of 44 patients with malignant salivary gland tumors in all sites who were observed for five years or more, 32 or 72.7 per cent survived five years. 相似文献

Six hundred and two mammary tumors were examined clinically, by mammography and cytology, with a histologic checkup following surgical biopsy. There were 247 cases of malignoma and 355 benign cases. The limited reliability of the individual methods is demonstrated, and it is shown that their combined use can improve the diagnosis. More malignomas are detected, and preoperative diagnosis is made more safely. If all three methods yield identical results, as was the case in 50.2% of the malignant and 32.7% of the benign lesions, the probability of diagnostic error is less than one per cent. With a malignoma thus established, surgical treatment may follow immediately, or irradiation can be started. In benign cases a surgical biopsy may be foregone and further developments may be awaited with due provision for regular control. If the three methods yield conflicting or doubtful results, elucidation by surgical biopsy and histology is indicated. 相似文献

CEA, ZGM and EMA localization in cells of pleural and peritoneal effusion: a preliminary study 总被引:1,自引:0,他引:1

Carcinoembryonic antigen (CEA), the zinc glycinate marker (ZGM) and epithelial membrane antigen (EMA) have been described as epithelial or tumour markers of varying specificity. These antigens were studied by immunoperoxidase localization in selected cell blocks of 62 pleural or peritoneal effusions and compared to cytological findings and review of the clinical records. By cytological criteria, 25 of the cell blocks were positive for malignancy, 30 negative, and 7 inconclusive. CEA, ZGM, and EMA by immunoperoxidase staining were localized on the cell surface and often in the cytoplasm of malignant cells, in 11/25 (44 per cent), 17/25 (68 per cent) and 22/25 (88 per cent) of the positive cell blocks respectively. Ten (40 per cent) of these cases were positive for all three antigens, 7 (28 per cent) for two, and 6 (24 per cent) for one. Of the 7 cases which were inconclusive on routine cytological reporting, 5 were positive for at least one marker. In 3 of the 5 a diagnosis of malignancy was confirmed, and in the other two was strongly suspected as malignant on clinical grounds. Macrophages were sometimes positive for one or more markers (but showed cytoplasmic staining only) and mesothelial cells in some cases stained positively for EMA but were always negative for CEA and ZGM. Localization of the 3 antigens in cells of malignant effusions was compared with their localization in the primary tumours in 9 cases. Localization corresponded for CEA in 7 of 9 cases, for EMA in 8 of 8 an for ZGM in only 2 of 9. Effusion fluid levels for CEA were compared with the cytological and immunocytochemical findings in 30 cases. Mucin stains performed on the cell blocks were also compared with the immunoperoxidase findings. 相似文献

Pefloxacin was used in the treatment of 25 patients with wound infection in a dose of 400 mg orally twice a day for 10-12 days. As the monotherapy it was applied to 15 patients. 7 patients with clinical signs of non-clostridial anaerobic infection were treated with pefloxacin in combination with intravenous metronidazole. Pefloxacin was highly efficient in 96 per cent of the cases with extensive posttraumatic purulent wounds with and without bone affection, acute purulent wounds of the soft tissue, purulent wounds of the soft tissues in diabetic patients, trophic or decubitus ulcer. 266 clinical isolates of Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Proteus mirabilis, Enterobacter spp. and Acinetobacter spp, were tested and 75 to 100 per cent of them was shown to be susceptible to pefloxacin and ciprofloxacin. At the same time the isolates of Pseudomonas aeruginosa and Klebsiella spp. were more susceptible to ciprofloxacin. The pathogen eradication and eradication with superinfection in the cases treated with pefloxacin amounted to 92 per cent. The drug tolerance was good. No clinically significant adverse events were recorded. 相似文献

In a series of 240 cases of perforated peptic ulcer prior to 1952 there was a total mortality of 17 per cent. This included cases treated conservatively as a planned procedure or because of other morbid conditions and undiagnosed cases, all ending in death.In cases treated by simple suture, mortality was 2.6 per cent for patients under 50 years of age and 17 per cent for those over 50, the rate rising very steeply with each decade over 50.From 1953 through 1959 selective gastric resection was carried out, the operation being done in all cases of perforated gastric ulcers, of chronic duodenal ulcers and of perforations associated with hemorrhage.During this period 303 perforated ulcers were treated, with a mortality of 15.5 per cent. Patients with associated morbid conditions and those admitted moribund and died, or died undiagnosed were again included.In this series also the mortality increased steeply from age 50 onward.Gastric resection was carried out in 148 cases of perforated peptic ulcer with a mortality of 6 per cent. In 105 cases under 60 years of age there were no deaths but in those over 60 the mortality rate was 21.8 per cent. Results in the patients who had resection, as determined after three years of observation, compared favorably with the results in patients who were treated by suture.The mortality of perforated ulcers in females was higher than in males.Emergency gastric resection has a definite place in the treatment of perforated peptic ulcer. 相似文献

A total of 1488 examinations of the conjunctival content of patients with various ophthalmic diseases were performed within 5 years (1973--1977). 989 (66.4 per cent) cultures were isolated. Staphylococci were isolated in 79.2 per cent of the patients irrespective of the diagnosis. The plasma-coagulating strains were isolated in 43.6 per cent of the patients with acute conjunctivitis. The plasma-negative staphylococci were more frequent in chronic conjunctivitis (83.5 per cent). A total of 188 strains were studied according to 18 tests. Determination of the antibiotic sensitivity showed that the number of the benzylpenicillin and tetracycline resistant strains among the plasma-coagulating staphylococci was higher in the patients with acute ophthalmic diseases. In chronic conjunctivitis no differences in the antibiotic sensitivity of the plasma-coagulating and plasma-negative strains were noted. Similar antibiotic sensitivity of all plasma-negative staphylococci irrespective of the diagnosis was found. High biological activity of the plasma-negative staphylococci was shown: 74.1 per cent of the isolates possessed phosphatase, 59.8 per cent possessed protease and 88.4 per cent a lysozyme-like enzyme. The strains isolated in chronic conjunctivitis produced protease more frequently that those isolated in acute ophthalmic diseases. 相似文献

OBJECTIVE: Fine needle aspiration cytology (FNAC) of lymph nodes can be used routinely as a first-line diagnostic test. The majority of studies reveal a malignant cause for palpable supraclavicular lymph nodes. The present audit further emphasizes the use of FNAC as a first-line investigation for the evaluation of enlarged supraclavicular lymph nodes. METHODS: A total of 200 cases of palpable supraclavicular lymph node(s) were included in the present study. RESULTS: Left supraclavicular lymph nodes were found to be more commonly involved (59.5% cases). Sixty-four per cent cases showed metastatic deposits and 13.5% cases were diagnosed as tuberculosis. Ten per cent cases showed reactive lymphoid hyperplasia; 0.5% (one) case showed only necrosis and on autopsy, a microscopic focus of choriocarcinoma was found in the testis. In 7.5% cases, diagnostic material could not be aspirated despite repeated attempts. Common metastatic tumours were from lung (22% cases), breast (16.4% cases), cervix (11% cases) and oesophagus (8.6% cases). In 13.3% cases the primary site was unknown and the diagnosis of malignancy first came from FNAC. CONCLUSION: The present study further highlights the importance of FNAC as a first-line diagnostic modality in the evaluation of supraclavicular lymphadenopathy. A full history, radiological findings and immunochemistry in difficult cases can help to arrive at a definitive diagnosis. 相似文献

The IHA test was evaluated in the diagnosis of amoebiasis. Axenically-grown E. histolytica was used as an antigen. A total of 427 sera from symptomatic (intestinal and extra-intestinal) amoebiasis patients. asymptomatic carriers, patients with parasitic intestinal infections other than E. histolytica, and healthy controls were tested. From 288 symptomatic cases of amoebiasis, 232 (80.6 per cent) gave positive reactions. In 93 asymptomatic cases of amoebiasis, 55 (59.1 percent) were seropositive. In testing of sera from 16 subjects with parasitic intestinal infections other than E. histolytica, a low-level positive IHA titres occurred in 2 (12.5 per cent). The test was also positive with a low titre in 3 (10.0 per cent) of the 30 subjects of the healthy control group. The results indicate that the IHA test is of value in the confirmation of intestinal and extra-intestinal amoebic infections especially in cases where the parasite is difficult to demonstrate. 相似文献

This report of eight years' experience with extrauterine pregnancy by a single gynecologist is an exposition of how the diagnosis was made or why it was missed. Of 26 diagnoses of ectopic pregnancy, five were false (20 per cent); and in three cases (10 per cent) the diagnosis was not made promptly-a total error of 30 per cent. Ectopic pregnancy will be discovered earlier if obstetric patients are always examined shortly after missing the first menstrual period.A palpable adnexal mass was present in 19 of 21 ectopic pregnancies (90 per cent). A mass was palpable in only one of five cases erroneously diagnosed as ectopic pregnancy (20 per cent).Decidual casts were passed by four patients, two of whom did not have ectopic pregnancy. If two gynecologists do not agree on the question of extrauterine pregnancy, a third opinion should be sought or culdoscopy employed. Enucleation of the conceptus and salvage of the oviduct is advocated. 相似文献

One hundred cases of common bile duct explorations were reviewed in an attempt to obtain information that might give insight into the diagnosis and definitive treatment of choledocholithiasis. Fifty of the hundred patients had common duct stones. Correlations were made between the incidence of choledocholithiasis as proved at operation, and the following factors: Kind and number of choledochal exploratory criteria used, the clinical diagnosis of common duct stones, and the pathologic features of gallbladders removed. The incidence of stones was statistically related to aging. The most frequent choledochal exploratory criteria were common duct dilatation or thickening (63 cases) and history of jaundice (50 cases). The most reliable single criterion in "diagnosing" common duct stones was palpable common or hepatic duct stones, the diagnosis having been correct in 15 of 17 such cases. The most reliable combination of criteria was a history of jaundice, plus palpable stones, with correct diagnosis in all such cases. The clinical diagnosis of choledocholithiasis was correct in only 17 per cent of cases. The correlation of the incidence of common duct stones with the degree of gallbladder disease-that is, acute or chronic-did not provide information that might be helpful in diagnosing choledocholithiasis. The incidence of proven retained common duct stones was 3 per cent, the non-fatal postoperative complication rate was 21 per cent and operative mortality was 1 per cent. 相似文献

The long, occult phase of pre-invasive carcinoma of the uterine cervix provides the clinician with his greatest opportunity in the actual prophylaxis of invasive cancer. By the use of four-quadrant biopsies and Papanicolaou smears, the authors increased by almost 20 times the frequency of diagnosis of preinvasive carcinoma of the uterine cervix.Radiation therapy of invasive carcinoma in 147 patients produced five-year “cure” in 84 per cent of stage I cases, 65 per cent of stage II cases. The over-all rate for stages I to IV, inclusive, was 51 per cent.Surgical management of this form of cancer, with preservation of the urinary tract, is an inadequate operation as judged by the extirpative standards observed in operations for cancer at other major anatomical sites.Improvements in technique of irradiation, more accurate measurements of depth dosage at critical sites, and more uniform dosage throughout the parametrial areas, have decreased the incidence of major complications of irradiation.Radical panhysterectomy and pelvic node dissection should be reserved for patients proved to have radioresistant lesions.The application of routine block dissection of pelvic nodes for Stage I and Stage II lesions, clinically controlled by irradiation, is of doubtful theoretic, and no evident practical value.Subject to future evaluation, pelvic eviscerative procedures seem to offer some salvage in cases of recurrent (occasionally primary) advanced lesions in rigidly selected patients. 相似文献

Cerebral arterial occlusion is a fairly frequent condition. We have diagnosed nine cases by cerebroangiography in the past two years, and there are many patients not given this special examination.Precise diagnosis has become more important as advances in therapy make prognosis more hopeful. The symptoms are various according to the location and degree of occlusion and the amount of collateral circulation.Angiographic diagnosis is not difficult, but repeated demonstration of the block should be insisted on. This is best done with multiple exposures after a single injection of contrast medium. We use 7 cc. of 50 per cent Hypaque(R) and one exposure per second through the arterial, capillary and venous phases. The films should cover the entire head and neck lest an occlusion in the common carotid be overlooked. We have found the Schonander biplane apparatus very satisfactory, using films 14 inches square and exposing them in anteroposterior and lateral projections simultaneously. 相似文献
