The Diagnositc Air Enema Treatment in Childhood with Acute Intussusception (An Analysis of 198 Cases) / 实用放射学杂志

Objective To study the influence factors of gas enema reduction intussusecption and increase the reduction success rate.Methods The authors retrospectively reviewed the acute intussusception of 198 cases(200 attempts)in childhood treated by automatic intussusception reductor,and exerted by massage with hand .Statistical analysis and discussion were made between reduction success rate and disease duration,the position of apex of intussusception,systemic situation and methods.Results Of 198 cases,ileocolonic intussusception 160 patients(80.8%),Cecocolic intussusception 21 patients(10.6%),colocolonic intussusecption 17 patients(8.6%),air enema reduction rate was 83% overall in childhood with acute intussusception.Statistical analysis indicated that the successful rate of reduction came down by degreess of the intussusception along with the disease duration and from near to far of the location of intussusception.The results were compared using X 2 test (?

Objective To analyse the imaging characteristics of pulmonary tuberculosis(TB) in elder in order to improve its diagnostic accuracy.Methods Radiological and CT fndings of pulmonary tuberculosis in 200 old patients were analysed retrospectively.Results The types of TB in 200 patients were:type Ⅱin 13 cases(6.5%),type Ⅲ in 163 cases (81.5%),accompanied with the pleuritis in 44 cases(22%) and type Ⅳ in 24 cases (12%).The mainly imaging findings included:old lesions in 85 cases(42.5%),exudative and/or multiplicative lesions in 81 cases (40.5%),caseous pneumonia in 47 cases(23.5%),cavitive lesions in 127 cases(63.5%),tuberculoma in 12 cases(6%),miliary nodules in 13 cases(6.5%),TB pleuritis in 68 cases(34%) and enlargement of lymph nodes in 57 cases (28.5%).Conclusion TB in elder is of characteristics of atypical location and unstable morphology.

The X-ray Diagnosis of the Diabetic Pedipathy(Foot)(An analysis of 20 cases) / 实用放射学杂志

Objective To improve the recognition of diabetic pedipathy through analyzing the X-ray findings of 20 cases.Methods Total 850 patients of diabetic mellitus were collected since 1985, of them,there were 20 cases with the complications of osteoarticulation or soft tissue of foot. The X-ray findings combined with clinical information were analysed.Results X-ray characters included:(1) osteoporosis in 20; (2) symmetrical atrophy of diaphysis in 14;(3) osseous absorption and destruction on the distal end of the bones in 11;(4) osteoarthritis in 7;(5) Charcot articulation in 2;(6) soft tissue swelling in 20, 5 of them having calcified vessels in area of metatarsus and phalanx.Conclusion For the patieuts with long-term diabetes without regular treatments, with repeating infection and even developing to obstinate ulceration on foot, the possible of diabetic pedipathy should be concerned. In order to obtain early diagnosis and effective therapy, it is necessary to take X-ray examination.

Localized Diagnosis of the Non-metallic Foreign Body in Lower Respiratory Tract(An Analysis of 150 Cases) / 实用放射学杂志

Objective To explore the main X-ray feature of the non-metallic foreign body in lower respiratory tract in order to improve the diagnostic accuracy.Methods X-ray findings of non-metallic body in lower respiratory in 150 cases proved by tracheobronchoscopy were retrospectively analyzed.The changes of heartshadow,mediastinum pulmotransparency and diaphragm during the procedure of deepbreath were observed under fluoroscoopy in different position,based on that the location of foreign body was evaluated.Results The distribution of foreign bodies in all patients included:38 cases in trachea,81 cases in right bronchus (25 cases in right primary bronchus,4 cases in upper lobar bronchus,5 cases in middle lobar bronchus,47 cases in lower lobar bronchus and segmental brouchus),31 cases in left bronchus (13 cases in left primary bronchus,2 cases in upper lobar bronchus and 16 cases in lower lobar bronchus).Because of the anatomical difference,the foreign bodies usually saw in right lower lobar bronchus.Conclusion Those patients who were suspected with foreign bodies in lower respiratory tract should be routinly examined by X-ray including fluoroscopy which is of important value in localized diagnosis of non-metallic foreign body in lower respiratory tract.
