[Prevention of development of hip joint instability in patients with the spastic form of juvenile cerebral palsy].

PURPOSE OF THE STUDY: How effective are the hip adductors and flexors tenotomies for the correction of unstable hip joint in cerebral palsy? MATERIAL: The study included 45 children with contractures of the hip adductors and flexors and hip subluxations due to spastic cerebral palsy. Thirty three of them were boys and 12 were girls. Their ages ranged from 2 to 13 years. Preoperative and postoperative roentgenograms of 82 hip joints were investigated. METHODS: Open tenotomies of m. adductor longus and brevis, m. gracilis, m. rectus femoris and m. psoas major. The immobilisation by POP casts lasted for 6 weeks. Abduction and extension bracing followed the plaster removal in all children. The hip joints were radiographed in neutral rotation both before and at least 6 months after the operation. Reimers migration percentage (MP) and Wiberg angle (CE angle) known as the parameters of hip instability were assessed. The obtained data were statistically analysed. RESULTS: The preoperative MP was below 25% in 25 hips, between 25 and 39% in 33 hips, between 40 and 59% in 14, and over 59% in 10 hips. The analysis of postoperative roentgenograms showed the following MP distribution: 56 less than 25%, 23 between 25 and 39%, and 3 greater than 40%. No postoperative MP was higher than 49%. 54% formerly subluxated hips achieved normal MP. The difference between preoperative and postoperative MP was statistically significant (P < 0.001). Before the tenotomies 24 hips were normal with CE angle over 20 degrees. It was between 20 degrees and 11 degrees in 28 cases and between 10 degrees and 1 degree in 17 cases. The preoperative CE angle was negative in 13 cases. Postoperatively CE angle was higher than 20 degrees in 53 hips. It was between 20 degrees and 11 degrees in 22 cases and between 10 degrees and 1 degree in 7 cases. The minimum CE angle after soft-tissue release was 4 degrees. The difference between preoperative and postoperative CE angles was statistically significant (P < 0.001). MP improved in 93% and CE angles in 96% of cases. DISCUSSION: Classical tenotomies of the spastic hip adductors used to be recommended in prevention of the hip subluxation in cerebral palsy patients. MP improved in 70% of cases in the Reimers' study (1980) based on selective adductors tenotomies. If the soft tissue release was unsuccessful bony operation was indicated. Kalen and Black claimed in 1985 that if psoas tenotomy was performed in addition to adductors tenotomies MP improvement was attained in 80-100% of cases. CONCLUSION: Adductors and flexors tenotomies can correct the spastic hip joint instability fully and permanently if the operation is performed prior to bony changes of the hip. The operation being followed by appropriate immobilisation and physiotherapy increases the percentage of good results.

Inflammatory pseudotumor of the lung in a coal miner with pneumoconiosis.

Inflammatory pseudotumors of the lung are uncommon and etiologically diverse lesions that often present as solitary masses in the lung. It may be difficult to distinguish these lesions from more commonly encountered lung neoplasms. Inflammatory pseudotumors can also occur in other organs, but the lung is most commonly involved. We describe a 63-year-old male coal miner with a 40-year history of dust exposure, who had a large right middle lobe mass on chest roentgenograms, with slow growth over the 7 years prior to admission. Repeated transthoracic echo-guided biopsies of the mass were indicative of an inflammatory and reactive process. The radiographic, histologic, and clinical findings indicated a diagnosis of inflammatory pseudotumor. The patient refused surgical intervention and was regularly followed at our outpatient clinic. Follow-up chest roentgenograms for 1 year revealed that the tumor size was stable. This case suggested that inflammatory pseudotumor, although uncommon, should be included in the differential diagnosis in a patient with pneumoconiosis and a solitary mass in the lung.

Echocardiographic assessment of total anomalous pulmonary venous connections in pediatric patients.

BACKGROUND AND PURPOSE: Cardiac catheterization can be superfluous and risky for sick babies, infants, and young children with total anomalous pulmonary venous connection (TAPVC). This study assessed the accuracy of echocardiography in the clinical assessment of pediatric patients with TAPVC before cardiac surgery. PATIENTS AND METHODS: A total of 15 consecutive patients with TAPVC treated between July 1, 1993, and December 31, 1999, were included in this retrospective study. Patients with TAPVC with heterotaxy syndrome were excluded. We assessed this cardiac anomaly preoperatively using plain chest roentgenograms, echocardiography, and magnetic resonance imaging. A combination of suprasternal, parasternal, subcostal, and apical four-chamber views and their tilting scans were employed for diagnosis and to trace the course of the anomalous pulmonary venous connection. RESULTS: Interatrial right-to-left shunt via atrial septal defects were documented by two-dimensional echocardiography with color Doppler mapping in all 15 patients. Patent ductus arteriosus was found in six patients. Cardiomegaly with enlargement of the right atrium and the right ventricle could be seen on plain chest roentgenograms and by echocardiography in all but two patients with infracardiac TAPVC. In all patients, the left innominate vein, coronary sinus or right atrium, and portal vein were the draining sites of supracardiac, cardiac, and infracardiac TAPVC, respectively. A pattern of continuous flow without phasic variation, which is suggestive of stenosis of the pulmonary vein, was found in two patients with infracardiac TAPVC with obstruction. The surgical findings were reviewed and correlated well with those of the echocardiography. CONCLUSIONS: In infants and children with TAPVC, the drainage sites and flow profiles of the pulmonary veins can be exactly determined by Doppler echocardiography preoperatively, which makes cardiac catheterization and angiocardiography unnecessary.

Tuberculosis in Thai prisons: magnitude, transmission and drug susceptibility.

BACKGROUND: Because of the human immunodeficiency virus (HIV) epidemic, tuberculosis has reemerged as a major public health problem in Thailand. Prison inmates are at high risk for developing tuberculosis because of the high prevalence of HIV infection. OBJECTIVES: To determine the magnitude, transmission, and drug susceptibility of tuberculosis in Thai prisons. SETTINGS: Four provincial prisons in Southern Thailand. DESIGN: Cross-sectional, descriptive, clinical and molecular study. RESULTS: Miniature chest roentgenograms were performed on 304 (6.4%) of 4751 inmates screened for a > or = 2 week history of chronic cough and fever. At least 17 (35%) of 49 inmates who had a miniature chest roentgenogram compatible with tuberculosis were HIV-positive. The prevalence of smear-positive pulmonary tuberculosis was 568 per 100,000 inmates, which was eight times higher than that in the general population. Eight (38%) of 21 culture-positive Mycobacterium tuberculosis isolates had DNA fingerprints matching those of another inmate who was housed in the same room or in the same dormitory unit; 39% of the M. tuberculosis isolates were resistant to isoniazid; three of these isolates were also borderline resistant to rifampicin. CONCLUSION: The prevalence of pulmonary tuberculosis in these prisons was high. A substantial proportion were acquired in the prisons. Isoniazid (INH) resistance was common, and theoretically precludes the use of INH-preventive therapy for contacts of these cases. Active case finding should be done and directly observed therapy implemented to prevent the spread of tuberculosis into the community.

[Giant left atrium combined with mitral valvular disease: morphologic classification and its clinical significance].

OBJECTIVE: To study the morphologic classification and its clinical significance of giant left atrium (GLA) combined with mitral valvular disease. METHODS: Between January 1993 and December 1999, a total of 62 consecutive patients with mitral valvular disease, whose preoperative left atrial endodiastolic volume index >/= 300 ml/m(2) or endosystolic diameter >/= 6.0 cm, were enrolled as research candidates. Morphologically, GLA was classified by Q Hierarchical cluster analysis according to the right or left side cardiothoracic ratio of the left atrium (r- or l-LATR) on an anteroposterior chest roentgenogram and the ratio of the distant diameter of the left main bronchus to the approximate diameter of the left main bronchus (LBDd/Dp) or to the trachea (LB/TR) on an left anterior oblique chest roentgenogram. RESULTS: According to r-LATR and l-LATR, the morphology of GLA was classified clinically into three types: type L (l-LATR >/= 0.6 and r-LATR < 0.58), type R (r-LATR >/= 0.58 and l-LATR < 0.6) and type B (r-LATR >/= 0.58 and l-LATR >/= 0.6). According to LBDd/Dp and LB/TR, GLA in type L and B was further classified into two subtypes, respectively: left posterior downward type (L(I) and B(I)), in which LBDd/Dp is equal or exceeds 0.38 or LB/TR is equal or exceeds 0.33, and left posterior upward type (L(II) and B(II)), in which LBDd/Dp is less than 0.38 or LB/TR less than 0.33. CONCLUSION: The morphologic classification of GLA may represent the main pathophysiological changes of GLA and might be a guideline for the selection of the optimal plication procedures of GLA in patients with valve diseases.

Sarcoidosis presenting in patients older than 50 years.

BACKGROUND: Sarcoidosis occurs most often between 20 and 40 years of age, but also presents in children and older adults. Newly diagnosed sarcoidosis in older patients has received little attention. In order to characterize sarcoidosis in older patients, the clinical, radiographic and laboratory features of sarcoidosis presenting in patients aged 50 or older were compared to patients whose sarcoidosis was diagnosed at an earlier age. METHODS: The medical records of 181 consecutive patients with sarcoidosis were reviewed. They were divided into 92 patients diagnosed at 50 years of age or older (group A), and 89 whose diagnosis preceded age 50 (group B). RESULTS: Comparison of group A with group B revealed that the two groups were similar with regard to race, gender, smoking habits, common presenting symptoms, organ system involvement, pulmonary function data, radiographic stage, PPD status, and laboratory values. At the time of diagnosis, most patients in both groups presented with either respiratory symptoms or asymptomatic chest roentgenogram abnormalities. The most prevalent pulmonary function abnormality was reduced diffusing capacity in both groups. Most patients exhibited either stage I or II chest roentgenograms. Organ systems most commonly involved included lung, lymph nodes, and skin. CONCLUSION: Sarcoidosis presents with similar clinical features whether diagnosed in young adults or in patients over the age of 50. The diagnosis of sarcoidosis should be considered in patients presenting over age 50 with characteristic signs and symptoms including chest radiographic evidence of mediastinal lymphadenopathy.

Constrictive pericarditis presenting as massive ascites in children: report of one case.

Abdominal distension has been described as the most common presenting symptom in children with constrictive pericarditis. This report describes a 13-year-old boy who had abdominal distension with massive ascite and hepatosplenomegaly as an initial presentation. The physical signs of jugular vein engorgement and gallop rhythm as well as the pericardial calcification on the chest roentgenogram lead to the diagnosis of constrictive pericarditis. After ultrafast computed tomography and cardiac catheterization confirmation, the patient received a pericardiectomy with excellent relief of symptoms. Pathology of the pericardium reveals fibrocalcified change, but no acid fast stained bacillus nor granulomatous lesion was observed. The incidence of constrictive pericarditis with evident pericardial calcification in children is extremely low. The diagnostic value of the chest roentgenogram and physical findings for the constrictive pericarditis are addressed.

[Traumatic rupture of the diaphragm report of eleven cases (author's transl)].

This is a report of 11 cases of traumatic rupture of the diaphragm, 8 left, 2 right and 1 bilateral. In 10 cases the rupture occurred in multiple trauma victims of a violent accident. In one exceptional case a right rupture occurred after a minor trauma; it was followed by herniation of the right colon and half of tranverse, the liver remaining in the abdomen. The mechanisms and types of ruptures are analyzed. Early diagnosis is possible if one is conscious of the clinical signs in all cases of thoracic and abdominal trauma, and when correct and repeated roentgenograms are made of the thorax. If there is a doubt, digestive roentgenograms with contrast medium, pneumoperitoneum and a hepatic scintigram can confirm the diagnosis. In our cases diagnosis was set before operation 10 times in 11. Diaphragmatic rupture can cause serious complications: respiratory insufficiency, shock, intestinal occlusion and necrosis by strangulation. Operative indication is absolute as soon as the patient is out of shock, that the rupture be large or small, diagnosed early or late. The abdominal approach is best if operation is early, especially if one suspects associated abdominal lesions. Thoractomy is considered if the rupture is old. Mortality is not negligible (20%) partly because of associated fractures and visceral lesions.

Anterior cervical microforaminotomy for spondylotic cervical myelopathy: part 2.

OBJECTIVE: Anterior microforaminotomy for spondylotic cervical myelopathy is reported with surgical results. METHODS: A retrospective study was performed for 40 patients with spondylotic cervical myelopathy who had been surgically treated with anterior microforaminotomy at the University of Pittsburgh between April 1994 and June 1999. Age ranged from 32 to 74 years (median, 51 yr). Twenty-eight patients were men, and 12 were women. All had undergone magnetic resonance imaging (MRI) scans preoperatively. All underwent MRI scans and dynamic roentgenograms 6 weeks after the operation. The duration of follow-up ranged from 24 months to 86 months (median, 42 mo). RESULTS: Twenty-eight patients (70%) had radiculopathy in addition to their myelopathy. Single-level operations were performed in 13 patients (32.5%), two-level operations in 19 patients (47.5%), three-level operations in 5 patients (12.5%), and four-level operations in 3 patients. Eleven patients (27.5%) had excellent results, 21 patients (52.5%) had good results, and 8 patients (20%) had unchanged results 6 weeks after the operation. Thirty-five patients (87.5%) were discharged the day of or the day after their operation. In all patients, MRI scans revealed good anatomic decompression, and dynamic roentgenograms revealed good stability. Postoperative complications included temporary deltoid weakness in one patient and temporary voice fatigue in another patient. In a final survey of 30 patients, 16 patients (53.3%) experienced excellent results, 11 patients (36.6%) experienced good results, and 3 patients (10%) experienced unchanged results. Final outcome survey with modified Japanese Orthopedic Association score is reported in 25 patients. CONCLUSION: Anterior microforaminotomy provided good to excellent surgical results in 80% of the patients with minimal morbidities 6 weeks after the operation and in 90% of the patients at long-term follow-up. Spinal stability was well maintained in all patients.

Osteomyelitis: early scintigraphic detection in children.

The value of scintigraphy in the early detection of osteomyelitis is demonstrated in children who had signs and symptoms suggestive of bone infection. Nine patients between 2 and 13 years of age were evaluated with technetium Tc 99m diphosphonate bone scintigrams and roentgenograms. Blood cultures were performed in all patients, and bone biopsy or drainage was obtained in six patients. The diagnosis of osteomyelitis was made in seven patients; one patient had a subperiosteal abscess surrounded by osteomyelitis, and one patient had cellulitis. The seven children with osteomyelitis had focal increase of radiopharmaceutical uptake in the bone. The child with the subperiosteal abscess had an area of decreased uptake in the center of the abscess surrounded by a zone of increased uptake of the radioactive bone-seeker. The patient with cellulitis had soft tissue changes by X-ray and a normal bone scintigram. In the seven patients with osteomyelitis, the bone scintigram was performed during the early phase of the disease and no bony changes were present on the roentgenogram. In one patient with subacute osteomyelitis, soft tissue changes were seen radiologically. Only three of the seven children with osteomyelitis developed radiological bony changes. Since bone scintigraphy can detect early local bone derangement, it is recommended in the initial evaluation of children in whom osteomyelitis is suspected.

[Two patients with pseudogout manifested by severe neck pain].

We reported 2 patients with pseudogout manifested by severe posterior neck pain. Patient 1 was a 78-year-old woman. She had experienced attacks of posterior neck pain several times for 4 years. On July 3, 2001, she developed severe pain in the posterior neck and left acromioclavicular joint, and was admitted to our hospital. On examination, her body temperature was 38.1 degrees C, ESR 140 mm/hr and CRP 14.7 mg/dl. Linear calcifications in meniscus of the right knee and left acromioclavicular joint were observed in roentgenograms. The CT of the cervical spines revealed multiple nodular calcifications in the ligamenta flava at the level of C3-C7. She was treated with NSAIDs, and her symptoms and inflammatory reactions rapidly subsided. Patient 2 was was a 76-year-old man. His clinical courses and laboratory findings were very similar to those of patient 1. Both patients presented here were older than 70, and shared such common clinical findings as back neck pain, fever, elevations of serum ESR and CRP level, and effiveness of NSAIDs. We could not detect any findings that could explain the neck pain and fever in cervical spinal roentgenograms and MRIs. Cerebrospinal fluid examinations showed no abnormalities. We diagnosed them as having cervical arthritis caused by calcium pyrophosphate dihydrate deposition (pseudogout) based on the cervical CT examinations, which showed multiple nodular calcifications in the ligamenta flava. Calcium pyrophosphate dihydrate deposition on cervical spine is very rare, and only 50 patients with this condition have been reported to date. In the literatures, the mean age of patients with cervical spine pseudogout is old (72.3 years old) and 84% of them are females. The ligamenta flava at the level of C3-C6 and transverse ligament of the atlas are most commonly involved. Pseudogout of the cervical spine should be considered as a differential diagnosis when we examine the elderly patients with back neck pain. Cervical spinal CT is the most sensitive and useful examination to diagnose this disease.

[Semimalignant skeletal tumors (author's transl)].

Osteoclastoma, chondroma and chordoma are tumors of the skeletal system which have some common features: in spite of benign histological findings their clinical course is that of a malignant neoplasm. They show an aggressive growth and a high rate of recurrencies mainly when the initial therapeutic procedure was insufficient. Osteolysis is the principal sign in the roentgenogram. However, there is no correlation between the roentgenogram and the dignity of the tumor. The best therapy is the radical operation. A good cooperation between surgeon, radiologist and surgical pathologist is very important for the prognosis of patients with this lesion.

[Preoperative planning and surgical technic in achieving stability and leg length equality in total hip joint arthroplasty].

One of the prerequisites for a good outcome of total hip arthroplasty is preoperative planning. Using a roentgenogram, the size of an implant, incision level on the femoral neck, depth required for fitting the cup, restoration of the center of hip rotation and, if necessary, correction of length descrepancy between the legs are determined. The preoperative planning based on an X-ray image was introduced by M. E. Müller and, in 1976, was modified by R. Schneider who used a transparent sheet for a template on which all relevant points guiding the surgical procedure are marked, i.e., the right position for implantation of the cup and stem, and incision lines. In uncomplicated cases, however, this approach is not necessary and the "planning principle of parallel lines" developed by L. Spotorno in 1988 can be used instead. The determination of length discrepancy between the legs is derived from a drawing of three reference lines on the roentgenogram. The lines parallel to each other indicace the same length for both legs. If the legs differ in length, the lines will diverge from each other in a way typical for this condition.

Screening for infectious foci in breast cancer patients prior to high-dose chemotherapy and stem cell transplantation.

UNLABELLED: Cancer patients treated with high-dose chemotherapy (HDC) followed by peripheral stem cell transplantation are at risk for infections during neutropenia. Our standard policy was to screen for potential infectious foci prior to HDC. Screening for infectious foci consisted of chest and sinus roentgenograms and a visit to the ear-nose-throat surgeon (ENT surgeon) and the dentist. The purpose of this study was to evaluate this approach. Between 1993 and 2000, 73 breast cancer patients received HDC. RESULTS: All chest roentgenograms were normal. ENT screening yielded in three (symptomatic) patients a potential infectious focus. In 32 patients (44%) a potential dental infectious focus was diagnosed and treated. During neutropenia after HDC clinical infections occurred in 15 patients (21%). In only 5 patients (7%) the infection focus was probably the upper respiratory tract. CONCLUSION: Potential ENT infectious foci were infrequent and all were symptomatic. Potential dental infectious foci were seen quite often; whether they would have had clinical impact if left untreated remains speculative.

Clinical and radiologic study of the frequency and presentation of chest infection in children with severe protein energy malnutrition.

The association between P.E.M. and frequent and severe life threatening infections including lower respiratory tract infections have been always reported. Lack of the usual general and local signs of infection in P.E.M. makes the diagnosis difficult and sometimes only postmortem. This study evaluated the frequency of chest infections as well as the sensitivity, specificity and predictivity of different signs and symptoms of the disease in 100 children with severe P.E.M. (marasmus, kwashiorkor, and marasmic kwashiorkor). Sixty two percent of the studied children had chest infection (33% pneumonia, 29% bronchitis). Although most patients were symptomatic, yet, signs and symptoms were few and mostly non specific. Chest roentgenograms are thus mandatory in evaluating patients with P.E.M. whenever possible. The only valuable signs suggestive of chest infection in P.E.M. were tachypnea (> or = 40/min) and/or chest indrawing. Both were moderately sensitive, highly specific and predictive of the disease particularly pneumonia. Their presence thus, its indicative of the need for early institution of antibiotic therapy even before the results of chest roentgenograms. Total Leucocytic count was of little diagnostic value while contrary to the common belief that tuberculin test is usually negative in P.E.M., the use of double the usual dose of P.P.D. (i.e. 10 TU) yielded positive reaction in some of the studied patients and thus must not be omitted from the routine investigations of malnourished patients.

[Foreign bodies in respiratory tracts of children treated at the Institute of Pediatrics in Krakow during the years 1987-1991].

Foreign bodies aspirated into respiratory tract may produce severe lung damage and threaten life. We have analysed retrospectively symptoms, physical findings, chest roentgenograms and bronchoscopy reports in 20 children with foreign body aspiration. Boys dominated in this group. Foreign body aspiration often accompanied by coughing, wheezing and vomiting. In chest X-ray examination it was revealed unilateral body trapping and obstructive emphysema. Foreign body aspiration should be considered in children with prolonged respiratory tract problems even when no adequate history is present and with negative chest roentgenograms.

Computed tomography in diagnosis of septic sacroiliitis: report of three cases.

Disorders of the sacroiliac joint are often overlooked during an initial physical examination because the patient is usually in a supine position and the posteriorly located joint is not accessible. Local pain and tenderness at the sacroiliac joint on lateral compression of the pelvis, together with Gaenslen and Fabere maneuvers, may direct the physician's attention to the joint. However, these symptoms are not specific or pathognomonic. Unusual presentation of septic sacroiliitis, which does not show radiologic changes during the early stages, may mimic gluteal, lumbar disc or intra-abdominal syndromes, leading to unnecessary abdominal exploration or lumbar discectomy. Computed tomography (CT), with its superb delineation of osseous, synovial and peri-articular structures, was applied to diagnose septic sacroiliitis in three patients. In Patient 1, septic arthritis and juxta-articular osteomyelitis with sequestrum formation were demonstrated by CT four weeks before abnormalities were shown on a roentgenogram. In Patients 2 and 3, inflammatory processes affected the synovium and peri-articular muscles; thus, abnormalities were shown by CT but not by a roentgenogram. We consider CT to be helpful and superior to conventional radiography in the diagnosis of septic sacroiliitis.

Occupational exposure and respiratory morbidity among asbestos workers in Taiwan.

To determine the prevalence of asbestos-related lung disease and the impairment of lung function among asbestos workers, we conducted a cross-sectional health survey of 459 workers in 33 asbestos-related factories in Taiwan. Each worker was asked about his medical and occupational history and was given a medical examination, chest roentgenogram and pulmonary function test. Manufacturing processes included production of asbestos cements, textiles, friction materials and insulation products. Exposure assessments were based on asbestos sampling and counting using a phase contrast microscope. The average age of the participants in the study was 41.6 years. They had an average of 8.1 years of dust exposure, with a range of one to 42 years. The majority had a cumulative asbestos exposure of less than 20 fiber years/mL. No case of asbestos-related lung disease was found during our investigation. No roentgenogram showed unequivocal changes of asbestosis. However, a multiple linear regression analysis of the pulmonary function test showed that both FVC and FEV1 decreased significantly with an increasing cumulative dose of exposure after controlling for age, height and smoking effects during analysis. FEV1/FVC and FEF25-75% were not affected by exposure dose. The absence of asbestosis and other asbestos-related lung diseases may be due to an inadequate induction time of asbestos exposure and a possible healthy selection of workers. We conclude that among workers in Taiwan, there is a significant effect on the respiratory system, especially pulmonary function, due to asbestos exposure.
