Total laparoscopic hysterectomy versus total abdominal hysterectomy: an assessment of the learning curve in a prospective randomized study.

The present randomized study was undertaken in order to compare the short-term results between total laparoscopic hysterectomy and abdominal hysterectomy in a centre with experience in laparoscopic surgery. From January 1997 to September 1998 inclusive, 102 women aged 44-71 years were randomly assigned to either total laparoscopic hysterectomy (n = 51 patients) or abdominal hysterectomy (n = 51 patients). The patients' demographic characteristics were similar in both groups. Average intra-operative blood loss was lower in laparoscopic hysterectomy than in abdominal hysterectomy (P </= 0. 001). The average time employed for laparoscopic hysterectomy was 104.1 +/- 26.98 min; according to the learning curve experienced in this study, the range was 72-163 min and the results after the plateau was reached showed no statistical difference between laparoscopic and abdominal operating times. The mean length of hospital stay was 2.38 +/- 0.30 days in the laparoscopic hysterectomy group versus 6.23 +/- 1.85 days in the abdominal hysterectomy group (P </= 0.001). In conclusion, this study shows that total laparoscopic hysterectomy can be effectively performed within reasonable time limits, provided that operators are experienced surgeons in operative laparoscopy and that operating times are comparable with those of abdominal hysterectomy.

Laparoscopic-ultrasonographic combined technique for the creation of a neovagina in Mayer-Rokitansky-Kuster-Hauser syndrome.

OBJECTIVE: To create a neovagina using a combined laparoscopic and ultrasonographic technique in Mayer-Rokitansky-Kuster-Hauser syndrome by modification of Vecchietti's operation. DESIGN: Case report. SETTING: Division of Physiopathology of Reproduction, University of Palermo, Palermo, Italy. MAIN OUTCOME MEASURE(S): The advancement of the needle from the pseudohymen, through the vesicorectal space using a triple contrast ultrasonographic technique. RESULT(S): The ultrasonographic scanning guides the accurate transit from external genitalia to the peritoneal cavity. CONCLUSION(S): This original approach allowed a safe and rapid creation of a neovagina in a case of Mayer-Rokitansky-Kuster-Hauser syndrome.

[Echography in assisted reproduction techniques].

The Authors describe the A.R.T. echoguided techniques, that can be routinely used in IVF/ET programs. All these techniques are simple and have replaced the previous ones. The echoguided oocyte recovery is now widely accepted instead of the laparoscopic way: the gamete intrafalloppian transfer can be easily performed under local anesthesia; the selective fetal reduction in cases of multiple pregnancies can be easily carried out on an outpatient basis.

Initial experience of a new linear everting falloposcopy system in comparison with hysterosalpingography.

OBJECTIVE: To assess the endolumenal portion of the fallopian tube from ostium to fimbria using a specially designed linear everting catheter and microendoscope. The study compared falloposcopy results with those obtained with hysterosalpingography (HSG) in the same patients and explored the system's ability to classify internal tubal conditions. DESIGN: A prospective study of a new diagnostic technique, falloposcopy, versus conventional means of evaluating tubal status. SETTING: A tertiary university infertility center. PATIENTS: Eighteen infertile patients with a previous history of infertility of at least 2 years duration. INTERVENTION: Diagnostic falloposcopy was performed on a total of 31 tubes. RESULTS: Although the results of HSG and falloposcopy were in agreement in 19 cases, falloposcopy findings were at significant variance with HSG in 12 cases (40%). Seventeen of the tubes visualized by falloposcopy were considered to be normal, 10 showed mild disease, and 4 were severely damaged. CONCLUSION: Falloposcopy using the linear everting catheter is rapid and atraumatic. It provides more complete information concerning tubal status than HSG and as such constitutes an important advance in diagnosis and therapy planning.

[Early myoclonic encephalopathy. Delimitation of the syndrome in view of genetic counseling].

Early myoclonic encephalopathy is a rare neurologic disease of unknown etiology whose course is always quickly unfavorable. Clinical features include lack of mental development and myoclonic jerks which appear during the neonatal period. There are no biological abnormalities but EEG shows a pattern of suppression-burst. In the spectrum of neonatal epileptic encephalopathic syndromes, it is important to distinguish this syndrome from non-ketotic hyperglycinemia and Ohtahara' syndrome. Two new familial cases authors to emphasize on the difficulty of nosological delineation of these syndromes. However it is necessary to delimit this disease for a genetic purpose.

Maturation of peripheral nerves in preterm infants. Motor and proprioceptive nerve conduction.

The peripheral nerve maturation (proprioceptive and motor nerve conduction velocities (PNCV and MNCV] was studied in 3 groups of newborn babies. Two groups of premature babies (PT), studied when they reached the expected date of birth (group I, gestational age (GA) at birth 27-31 weeks, n = 13, group II, GA at birth 32-35 weeks, n = 9), were compared to 10 normal full-term newborns (FT). The MNCV of PT babies was similar to that of FT babies: group I 22.8 +/- 3.3 m/sec (X +/- S.D.), group II 24.9 +/- 4.3 m/sec, FT 25.7 +/- 3.9 m/sec. PNCV was significantly lower in group I (18.1 +/- 5.9 m/sec) than in group II (28.3 +/- 6.4 m/sec) and in FT babies (32.0 +/- 7.4 m/sec) (P less than 0.001). Such a delay in maturation could be partly responsible for the neurological impairment often observed in PT babies.

[Hemorrhagic colitis in newborn infants. Apropos of 32 cases].

The authors report 32 cases of neonatal hemorrhagic colitis observed during a 19-mth period in the neonatal unit of the University Medical Center of Caen. Neonatal hemorrhagic colitis is characterized by rectal bleeding alone occurring mostly in premature infants. There are no accompanying clinical, biological or radiological signs of necrotizing enterocolitis. The evolution is always benign without any particular therapy. Prematurity and cesarean section appear to be the most important etiological factors. The pathogenesis is probably multifactorial. The differential diagnosis with necrotizing enterocolitis is difficult in the beginning.

Maturation of peripheral nerves in preterm infants: proprioceptive and motor nerve conductions of tibial nerve.

Premature birth induces a profound change in the environmental factors affecting nerve maturation. The proprioceptive sensory and motor nerve conduction velocities (NCV) of the posterior tibial nerve, which reflect peripheral nerve maturation, have been measured in 3 groups of newborns. Two groups of premature (PT) babies, studied when they reached the expected date of birth (group I, gestational age (GA) at birth, 28-31 weeks, n = 8; group II, GA at birth, 32-35 weeks, n = 6) were compared to 9 normal full-term (FT) newborns. As previously shown, the motor NCV of PT babies at a post-conceptional age close to term is similar to that of FT newborns: group I, 22.70 +/- 2.95 m/s (mean +/- SD); group II, 25.90 +/- 4.61 m/s; FT, 25.48 +/- 4.09 m/s. The proprioceptive sensory NCV was significantly lower in group I (21.59 +/- 4.39 m/s) than in group II (31.89 +/- 4.15 m/s) and FT newborns (32.22 +/- 6.56 m/s) (p less than 0.01). Such a delay in maturation could be responsible for the subtle clinical dysfunctions often observed in PT babies.

[Nutritional management of neonates and infants with cystic fibrosis of the pancreas detected at birth].

From a systematic neonatal screening for cystic fibrosis in the Basse-Normandie area and to prevent disorders of the intestinal transit related to malabsorption, neonates then infants were given a semi-elemental hypercaloric diet, with supplements in nitrogen, MCT, minerals, vitamins and low in LCT. Diets were adjusted every month during a consultation using clinical and biological parameters. Results in the first 14 children showed that clinically as well as biologically, these children may remain within the normal range, avoiding the previously reported growth retardation and mineral or vitamin deficiencies. This procedure should allow an improvement in the quality of life and prognosis of such children, by maintaining adequate nutritional status.

[Di George's syndrome complicated by graft versus host reaction].

On the occasion of a case of Di George syndrome, complicated by a post-transfusion lethal graft versus host reaction, the authors review its main clinical and biologic criteria. This case also shows that immune deficiencies should be diagnosed early in order to adopt preventive measures before transferring the patient in a specialized unit, where immunorestitution will be discussed.

[Cardiac tumors with neonatal disclosure. Apropos of a case with spontaneously favorable development].

The authors report the case of a cardiac tumour documented by 2 D echocardiography, presenting in the newborn with cardiac arrest. The echocardiographic features of multiple nodules disseminated in the ventricular walls suggested a diagnosis of rhabdomyoma. The initial course was complicated by poorly tolerated attacks of tachycardia which were rapidly brought under control with amiodarone. The long term outcome was clinically favourable with a rapid regression of the number and size of the tumours on echocardiography, and a tendency to normalisation of the electrocardiogramme. The possibility of regression, which has already been reported by many investigators, suggests that these cardiac tumours may have a better prognosis than previously thought.

[Proposal for a purely echographic classification of the polycystic ovary syndrome].

The authors analyze the application of ultrasonography in the morphological classification of PCO and standardize the types into three groups, which are directly linked in their progression from I to III with ovarian dimensions, with the number of follicular cysts and with the age of the patients, and which are inversely linked with the quantity of ovarian stroma and with the dimensions of the follicles themselves. Their conclusions regarding this auxiliary technique of examination and of prognostic and therapeutic evaluation are definitely positive.

Ultrasonographic evaluation of ovarian hyperstimulation syndrome, (O.H.S.).

The Authors have considered the possibility of avoiding the ovarian hyperstimulation syndrome, (O.H.S.), in women undergoing treatment with ovulation inductors, (Clomiphene citrate and gonadotropin) by means of repetitive ultrasonographic scansion beginning from the eleventh day of the cycle. They have come to the conclusion that there should be a routine use of ultrasound in order to avoid the moderate and severe forms of this syndrome.
