[Definition of normal criteria of provoked otoacoustic emission in the newborn infant].

Evoked otoacoustic emissions (EOE) were recorded with ILO88 in a group of 254 neonates (n = 508 ears) in order to determine the normative data. In this study, it was found that: (i) the mean EOE amplitude was 20.2 dB SPL, (ii) the EOE amplitude of the right ear was significantly higher than those of the left ear, (iii) the mean time necessary to record EOE in both ears was around three minutes, and (iv) EOE spectrum was large (mean = 638-5,611 Hertz). These data permit to precise the clinical interest of EOE for screening auditory function in neonates.

Congenital adrenal hyperplasia with female pseudohermaphroditism in a 26-year-old patient.

The paper presents the case of a 26-yr-old patient admitted for intersexuality. Clinical examination shows statural deficit, female phenotype, melanoderma, glabrous tegmina except for the pubic area presenting horizontally inserted pilosity, labioscrotum devoid of contents, pseudomicropenis with hypospadias. The Barr cytogenetic test is positive (56%) and hormone assay shows plasma cortisol at the lower limit and adrenal androgenic hormones and their metabolites in excess, suppressible by dexamethasone. The patient had a history of repeated admissions to intensive care units for severe dehydration, vomiting, diarrhea and collapse.

Room air ventilation for total intravenous general anaesthesia.

The use of room air alone to ventilate patients who were anaesthetized with total intravenous anaesthesia, including morphine 2 mg.kg-1, was studied in ten patients. The were scheduled for gastrectomy for peptic ulcer or stomach carcinoma. The patient's minute-ventilation was measured the day previous to surgery; this, together with a frequency of 14 c.min-1, was used to preset the ventilator. Alveolar ventilation, end-expiratory CO2, arterial blood gases and acid-base balance were monitored throughout the procedure. The blood oxygen level was found to remain similar to the reference value; there was a moderate hypocapnia, a low end-expiratory CO2 and minimal changes in acid-base balance. No pulmonary complication was encountered in the postoperative course. These results showed that room air could be used in unusual circumstances for healthy patients for whom a total intravenous anaesthetic technique has been chosen.

[Mechanical suture in colorectal surgery].

THE OBJECT: Of this work was the study of using, as well as the utility of the mechanical sutures in colorectal surgery; because of the special caution needed to be taken for any colonic or rectal suture, more than any other digestive segment. The frequency of the postoperative fistulas after the suture and anastomosis is higher at this level and so it increases the period and costs of the hospitalization. MATERIAL AND METHOD: We studied the possibilities of performing and evolution of 64 mechanical sutures for 19 patients, with colorectal pathology, hospitalized in our department from july 1999 to december 2000. RESULTS: We performed 64 mechanical sutures, as followed: 47 in open surgery and 17 in laparoscopic. From all these, 56 was bowel sutures, 8 of them were vascular (in laparoscopic, for cutting the most important vascular pedicles). We did 18 anastomosis: 15 in open and 3 in laparoscopic surgery. It was 2 postoperative fistulas from all 56 intestinal sutures (3.57%). We haven't any intra or postoperative bleeding from the vascular anastomosis. It was 3 intraoperative bleeding from the intestinal anastomosis, and only 1 case of postoperative bleeding (5.26% of the cases: 1.56% of all mechanical sutures). In only one case, the mechanical suture couldn't be initially done, but it succeeded after the removing of the segment of the bowel involved. CONCLUSIONS: Mechanical sutures offers a high level of safety to the colorectal anastomosis. It provides a very good vascularization to the anastomosis and decreases the time needed for performing the suture or anastomosis, versus manual sature. Also, for the patients with rectal ampular neoplasm, it creates the possibility of anal sphincter preservation by making a low colorectal anastomoses--which is difficult by manual suture.

[Intraoperative ultrasonography during laparoscopic surgery].

AIM: Of this study is the introduction and the results evaluation of laparoscopic ultrasonography performed. MATERIAL AND METHOD: We realize a prospective study about laparoscopic ultrasonography performed in 37 cases with laparoscopic surgical treatment. The Aloka SSD 2000 mobile scanner is used. This system make possible the use of an linear-array transducer, with mechanical flexibility and availability of Doppler analysis. Most frequently we used intraoperative ultrasonography in laparoscopic cholecystectomy as an alternative for cholangiography to exclude CBD pathology. Because of various surgical pathology with laparoscopic approach, the laparoscopic ultrasonography utilization range was vastly. RESULTS: In all the cases we could performed the laparoscopic ultrasonography. In 6 of 27 cases with laparoscopic cholecystectomy we found pathological disorders of bile ducts. CBD with diameter found between 5-12 mm. We properly saw the distal segment of CBD in 23 cases (89.2%), and common hepatic duct in 26 cases (97.3%). The quality of visualization was very good in 21 cases (83.8%) and moderate in 6 cases (16.2%). We easy identify CBD stones and we successfully used Doppler color mode in differentiating vascular from non-vascular from non-vascular structures. Laparoscopic ultrasonography performed in a case with left colon cancer excluded liver metastasis and lymph nodes metastasis. CONCLUSIONS: 1. Laparoscopic ultrasonography combines the advantages of diagnostic laparoscopy and intraoperative contact ultrasonography; 2. Laparoscopic ultrasonography is a simple and very efficient intraoperative examination procedure; 3. Laparoscopic ultrasonography is the technique to choose in CBD intraoperative exploration; 4. Laparoscopic ultrasonography improve abdominal malignancy exploration, thus modifying therapeutic decisions; 5. Color Doppler mode guides the surgeon's steps in difficult directions.

[Mechanical suture in classic and laparoscopic general surgery].

AIM: Of this working is the study of employment the mechanical suture in general surgery classic and laparoscopic. MATERIAL AND METHOD: We analysed the possibility of accomplishment and postoperatory evolution of 104 mechanical sutures performed in 24 patients, with diverse surgery pathology, operated in Department of General Surgery, between January 1999 and January 2000. RESULTS: Mechanical sutures allowed us to minimize the duration of surgical interventions and to perform some difficult anastomotic assembles (sometimes including creation of organ substitute). We had only two postoperatory fistulas and two postoperatory haemorrhages from anastomotic area (both cases because of bad closing of clips, through tissue excess between anvil and cartridge of the stapler). CONCLUSIONS: There are certain advantages in using mechanical sutures (versus manual sutures) consisting in decreasing of time period, both in operation itself and in hospitalization, despite their high level cost.

[Radiophotographic and simultaneous bacteriological detection in an industrial group].

After carrying out a complex investigation of the workers of a confections factory the authors detected 2 new cases of tuberculosis (0,5 0/00), with the aid of radiophotography and another 2 cases (3,4 per 1000 subjects examined) by bacteriological investigation of the subjects that coughed. These last 2 cases were detected between those that had a normal thoracic aspect on the radiophotographic film alone. The observation of the authors allows to conclude that a bacteriological investigation of the suspects following radiophotography is not sufficient and that this type of investigation should be extended to certain groups of the population that show broncho-pulmonary symptoms. The association of the two methods, in well-defined technical and organisational conditions will allow for a significant increase of the efficiency of systematic examinations for the detection of pulmonary tuberculosis.
