Severe farm machinery injuries to children--a report on 15 cases.

Fifteen children with 24 farm injuries were admitted to our institution during a 12 years period. Ten accidents occurred in boys and five in girls. They ranged in age from 1 to 15. The cause of fatal and non-fatal injury was farm machinery and especially tractor in 9/15. Fractures, lacerations and amputations were the most common injuries requiring multiple reconstructive surgical procedures. The magnitude of the problem requires emergency management in rural areas. However, educational programs with an emphasis on prevention by physicians, family members, educators and legislators is necessary to reduce the incidence of farm accidents.

[Testicular ectopy. Current concepts].

Testicular descent is a complex mechanism influenced by hormonal and anatomical factors. Whatever the age of the patient or the descent technique used for either one or both testes, there is a risk of degeneration and sterility counts. Anatomical studies and the results of sperm are important, hence the importance of establishing a precise anatomical and therapeutic classification.

[Radiographic study of the lumbar spine bearing weight in weight lifters].

Radiographies of lumbar spine at rest in standing position and upon a force of 100kg were undertaken in 19 young sportsmen. If comparison between two pictures demonstrated important modification in few subjects, statistical study shown only little variations. Clinical studies in weight lifters demonstrated effectively few lesions with a good training, it's possible to modifiate pelvic orientation and this pelvic support permits a optimal posture for the lumbar spine.

[Anatomic basis of the Lockhart-Mummery procedure in the treatment of total rectal prolapse in children].

From four pelvic cavities of adults (2 males and 2 females) and one of neonate the authors studies structures between rectum ventrally and sacrum dorsally. Always they found an avascular space behind the perirectal fascia in which were embedded arteries of rectum and above the presacral fascia with inside median sacral artery and sympathic trunks. This avascular space permit to made there surgically procedures such Lockart-Mummery to attach rectum to sacrum.

[Various mechanic characteristics of bony structures of the temporo-mandibular joint in several classes of mammals studied by measurement of hardness and resistance to penetration].

Applying the principles of mechanics, the authors have studied and compared the bony structures of the temporo-mandibular joint. Using the means of investigation usually implemented in the metallurgical sector, they have tried to establish a link between the morphology and mechanical strength of the various components of this joint in some subjects belonging to the mammals classification and with various feeding modes. The results obtained by hardness micrometry tend to show that during masticatory movements, the temporo-mandibular joint works in a hanging rather than in a compressed mode.

[Mechanics of the characteristic geometry of the human spine undergoing vertical pressure].

Since MAGENDIE in 1816, it has been a common assertion in books of Anatomie that curves of the spine increase its strength. This increase in strength has been estimated by a formula attributed to EULER: R = nc2 + 1 in which R is the strength and nc2 stands for the square of the number of curves. Applying the actual law of Euler on the strength of beams submitted to a vertical effort, the authors conclude that strength is increased by about 30% and not multiplied by 10, 16 or even 17 as is often falsely written.

Ultrastructural and immunohistochemical evidence of in situ differentiation of mononuclear phagocyte system cells in the interstitium of human fetal testis.

Ultrastructural and immunohistochemical studies were made of the testicular interstitial tissue from eight human fetuses of 15 to 27 weeks gestation. Three cell types developed in mesenchymal cells: Leydig cells and peritubular cells, as already reported, and cells of the mononuclear phagocyte system (MPS), which are located in the intermediate area of the interstitial tissue. Located at the periphery of Leydig cells, these gradually differentiate between 16 and 20 weeks and later acquire the ultrastructural characteristic of histiocytes during the involution phase of the fetal testis. Immunohistochemical studies using monoclonal antibodies (Mo Ab) to antigens of human myelomonocytic cells isolated a cell subpopulation in the interstitial tissue that is distinct from the peritubular (fibroblastic) and the Leydig cells. This subpopulation expressed all or some of these antigens according to their stage of differentiation; all cells are labelled by MY7 Mo Ab which is directed against myelomonocytic cells, including stem cell. Using monoclonal antibodies directed against more mature cells (MY4, MO1 and MO2), the number of labelled cells decreased in this mesenchymal population. MY4 Mo Ab, which detect myelomonocytic cells excluding stem cell, label fewer than MY7 Mo Ab. MO1 MO Ab and MO2 Mo Ab, respectively, directed against antigens of more mature or mature monocytic cells, label less number of mesenchymal cells, which are histiocytes after 20 weeks. These ultrastructural and immunohistochemical findings suggest that cells of the MPS differentiate within the interstitium.

[Long term complications of splenic artery ligation for haematologic problems in the child. A study of 7 cases].

Since 1983, the authors have performed a surgical ligation of the splenic artery in 7 patients suffering hypersplenism due to hematological diseases (4 Minkowski-Chauffard, 2 Betathalassemia Major, 1 Idiopathic Thrombocytopenic purpura). The immediate post operative course and long-term outcome of the patients were evaluated on clinical and biological grounds. The early post operative period was not influenced by the underlying hematological disorder. In all patients the hemoglobin, erythrocyte and platelet counts significantly increased and were related to functional hyposplenism. Delayed outcome depended on the underlying disease. Patients with Betathalassemia returned to preoperative status within months; thus, the only advantage of the arterial ligation was to transiently decrease the requirements in blood transfusion. Two patients with Minkowski-Chauffard disease did not present further episodes of acute hemolysis and did not required additional blood transfusion. On the other hand, the other two patients with Minkowski-Chauffard disease progressively returned to preoperative status, including severe episodes of hemolysis, and required a splenectomy be performed. Since the arterial supply to the spleen remains inchanged after the operation, it may be expected that the results (i.e. long-duration hyposplenism) could be improved by performing extensively devascularization of the spleen to complete the ligation of the splenic artery.

[An intracardiac needle without thoracic penetration].

The authors report on the asymptomatic case of a child with intra cardiac needle, which was discovered after systematic pre operative X Ray chest film. Surgical removal of this foreign body could be performed before any of its possibly lethal complications (50%).

[The role of total colonic electromyography in children in case of chronic constipation. Preliminary study].

Since December 1987, the chirurgical pediatric team in Clermond-Ferrand performs total colonic electromyography in children. This examination is integrated into a diagnostic and therapeutic protocol for chronic constipation. We used an intraluminal probe supporting 10 groups of 3 ring electrodes. Inside the probe a lead pellet was placed opposite each electrode. The probe was inserted through the colon by colonoscopy into a starving child. The recording starts 24 hours later and is registered for 3 hours before and 3 hours after a meal. The aim of this work is to report the preliminary results of 6 electromyography in constipated children.

[Post-traumatic intramural hematomas of the duodenum in children. Apropos of 2 cases].

Two children in whom the diagnosis of intramural duodenal hematoma was made have been treated. One patient had the hematoma evacuated at surgery and one was successfully managed with nasogastric suction and parenteral fluid administration. The non operative treatment for intramural duodenal hematoma is recommended after perforation of the duodenum (type IIB, III, IV) or other associated injuries requiring laparotomy have been satisfactorily excluded.

[Trial of a diagnostic score in painful abdominal syndromes suggestive of appendicitis in children over 3].

A diagnostic score was attributed to 82 children aged 3 to 16 years referred with suspected appendicitis. Results demonstrated the value of the score in increasing diagnostic precision and avoiding appendicectomy of histologically healthy organs and its complications. However, the score requires further development by study of a larger series and by integration of a criterion such as C reactive protein.
