[Conservative surgery of ovarian torsion in pediatrics]. / Cirugía conservadora de la torsión de ovario en pediatría.

The authors describe the case of two girls diagnosed of ovarian torsion secondary to a cyst. They were operated on by conservative ovarian therapy regardless the time of evolution and ovary macroscopical aspect. These 2 patients were 9 and 13 years old, with abdominal colic pain of 48 and 36 hours of evolution. The diagnosis by doppler sonography was ovarian torsion, with a 4 cms cyst in the right ovary in the first case and a 5 cms cyst in the left ovary in the second patient. Both patients were operated on. After untwisting the ovary, we instille warm saline solution to this ovary and, after waiting for 10 minutes, we resect the ovarian cyst and it recuperates partial and heterogeneous its pink colour. We advise to the family about the possibility of surgical reintervention if the ovary is not viable. After 10 and 12 days of surgical intervention, the Doppler sonography has confirmed the existence of ovary flow and the symmetry of affected ovary in comparation to the opposite on. At the present, both patients are asymptomatic, with exhaustive ultrasound controls. Ovarian torsion is the most frequent complication of ovarian tumours of pediatrics (3-16%) and this is a real emergency in gynecology. Traditionally, it has been recommended the exeresis of ovarian torsion. Regardless the blue aspect of isquemic ovary affected by torsion and the time of evolution, in our experience when there is a minimal possibility of ovarian viability, it is possible to follow a conservative therapy because the macroscopical aspect of the ovary is not necessarily related with the following evolution of the case.

[Boix Ochoa's antireflux procedure returns patients to normalcy: 24 hour esophageal pH monitoring of 21 cases]. / La plastia de Boix Ochoa reconvierte al enfermo a la normalidad. Estudio pHmétrico de 21 casos.

A great controversy exist concerning the surgical management of gastroesophageal reflux (GER). It is well known that Nissen procedure produces a hypercorrection of the gastroesophageal competency and often a "gas bloat syndrome". On the other hand, the Boix Ochoa's technique is more physiological but corrects GER allowing the persistence of a "radiological" reflux. The aim of the study was to demonstrate the accuracy of this procedure. 287 pediatric patients were studied because of GER and abnormal barium upper gastrointestinal series. 24 hours esophageal pH monitoring was performed in all this patients and in 21 the results were clearly pathological. They were operated on and six months later were new evaluated with upper GI series and continuous 24 hours esophageal pH monitoring. The results were compared with those previous to operation and also with a control group. Statistical great significance was found between presurgical and postsurgical data, what determine the efficacy of the procedure. No statistical significance was found between postsurgical data and the control group, what means that Boix Ochoa's procedure resolve GER without hipercorrection.

[Septic arthritis in children]. / La artritis séptica en el niño.

A review was made of 15 cases of septic arthritis in children. 13 of these cases corresponded to purulent arthritis, one to tuberculous arthritis and one to brucellar arthritis. All of them received diagnostic punction. Five joints received arthrotomy, by a washed-aspiration system. The antibiotic treatment was given approximately during for six weeks. We had two complications, die to a delayed diagnosis: one coxa valga and one capital femoral necrosis. It is important the insist on a early diagnosis and decompressive arthrotomy, specially in those cases in which the hip is the joint affected.

[Rib actynomycosis]. / Actinomicosis costal.

A unusual case of rib actynomycosis, observed several months after surgery for acute appendicitis in a 11 year boy is reported. Surgical excision of the affected segment of rib had to be implemented with lyncomycin in order to obtain the cure. Laboratory data are consistent with the above mentioned diagnosis.
