Venocclusive disease of the liver after allogeneic bone marrow transplantation in man.

One hundred and fifty-one consecutive patients underwent allogeneic bone marrow transplantation (B.M.T.

[Deep and localized hyperthermia of the liver induced by stereotaxic Nd-YAG laser irradiation].

Thirty six hepatic lesions (12-18 mm) of localized hyperthermia are induced in eleven pigs by means of a Nd-YAG laser. Laser shots of 80 W/10 sec. are transmitted through a stereotaxic handpiece coupled to a water cooling circulation protecting the optic fibre.

Deep localized neodymium (Nd)-YAG laser photocoagulation in liver using a new water cooled and echoguided handpiece.

Thirty-six deep hepatic lesions of localized photocoagulation were induced in 11 pigs by means of a neodymium-YAG laser. Laser applications of 80 W/10 sec (10.190 W/cm2) were transmitted through a handpiece coupled to a water-cooling circulation system to protect the quartz fiber and positioned through an echo-guided trocar.

[Hypertrophic kidneys in utero and neonatal renal failure caused by diffuse mesangial sclerosis].

The authors report an unusual mode of onset of diffuse mesangial sclerosis in a newborn. Fatal neonatal renal failure, and not infantile nephrotic syndrome, was the main symptom after birth. In utero, ultrasonography revealed hypertrophy and hyperechogenicity of the kidneys associated with oligoamnios.

Ultrasonic and histopathological correlations of deep focal hepatic lesions induced by stereotaxic Nd-YAG laser applications.

Thirty six deep focal hepatic lesions were induced in eleven piglets by means of an Nd-YAG laser. Laser shots of 80 W power and 10 s duration were used, the beam being transmitted through an echoguided stereotaxic handpiece. From day 0 to day 120, the animals underwent ultrasonographic and morphological controls.

[Benign liver tumor during pregnancy. Review of the literature and management (apropos of a case)].

The authors report a case of a tumour of the liver in a pregnant woman who had taken oral contraception for six years. Since oral contraceptives have become far more widely used the two benign tumours of the liver, namely a hepatocellular adenoma of the liver and focal nodular hyperplasia, have become far more common. The increased blood supply to the liver can make such a tumour symptomatic and increase the risk of it rupturing intraperitoneally, especially at the onset of labour.

Update on low dose rate irradiation for cancers of the oropharynx--May 1986.

At the conclusion of our recently published article in this Journal on low dose rate irradiation in moderately extensive cancers of the oropharynx, we updated our results in May 1986. Here we report on an expanded group of 65 patients with a 2 year minimum follow-up; 32 patients were treated by low dose rate irradiation and 33 by conventional fractionation. Forty-four percent (14/32) low dose irradiation patients survived with NED vs 8/33 (24%) conventional fractionation patients.

The indications for total cutaneous electron beam radiation therapy of mycosis fungoides.

From 1977 to 1984, we treated 34 patients with mycosis fungoides and 9 patients with B cutaneous lymphomas. Eighteen patients with mycosis fungoides were treated with total skin electron irradiation (TSEI) and had a minimum follow-up of 15 months (range 15 months to 7 years). The lowest electron energy of the linear accelerator was 8 MeV therefore we placed a plexiglas screen between the patient and the machine; the resulting electron energy was 4 MeV.

[Gastroesophageal reflux and esophageal atresia].

In 210 surviving cases of oesophageal atresia treated by anastomosis, 34% presented a gastro-oesophageal reflux. Half of these patients needed surgical treatment of the reflux to prevent complications.

[High-risk congenital diaphragmatic aplasia and hernia (apropos of 64 cases)].

The prognosis of high risk congenital diaphragmatic hernia and eventration diagnosed in the early neonatal period (before 24 h) is studied based on a series of 64 cases. Eventration has a poor prognosis with 5 deaths out of 7 cases. The replacement of the hemidiaphragm by an abdominal muscular flap seems to be the best surgical procedure (2 recoveries on 4 cases).

[Neonatal bilateral interstitial emphysema. Surgical treatment. Apropos of 1 case].

The authors report a case of respiratory distress secondary to inhalation of meconial amniotic fluid treated by mechanical ventilation, which was complicated by severe interstitial emphysema. Treatment by pleurotomy allowed a favorable evolution. The various therapies of interstitial emphysema of the neonate, in particular surgical technics are described.

Effects of prematurity and dysmaturity on growth at age 5 years.

Forty-two term and 106 preterm appropriate for gestational age (AGA), and 43 term and 31 preterm small for gestational age (SGA) children were observed from birth to age 5 years. Parents' weight and height were also measured in 193 subjects including 97 couples. The percentage of short children was higher in SGA (17%) than in AGA (3.

Radiation therapy for carcinoma of the pinna using iridium 192 wires: a series of 70 patients.

From January 1970 to November 1982, 70 patients with carcinoma of the pinna were treated by interstitial irradiation. An afterloading technique with Iridium 192 wires was used. One patient recurred and had a total pinnectomy followed by 60 Gy external radiation.

Interstitial radiation therapy for squamous cell carcinoma of the tonsillar region: the Creteil experience (1971-1981).

From July 1971 to December 1981, 33 selected patients with T1, T2 tumors of the tonsillar region were treated according to the following protocol: 1. Telecobalt therapy to the primary site and to neck nodes to a dose of 45 Gy. 2.

Concurrent overproduction of synapses in diverse regions of the primate cerebral cortex.

Synapses develop concurrently and at identical rates in different layers of the visual, somatosensory, motor, and prefrontal areas of the primate cerebral cortex. This isochronic course of synaptogenesis in anatomically and functionally diverse regions indicates that the entire cerebral cortex develops as a whole and that the establishment of cell-to-cell communication in this structure may be orchestrated by a single genetic or humoral signal. This is in contrast to the traditional view of hierarchical development of the cortical regions and provides new insight into the maturation of cortical functions.

[Conservative treatment of breast cancer. Results after 10 years].

Between 1961 and 1975, 300 women with cancer of the breast (T1:72; T2:167; T3:61) were treated conservatively with radiotherapy alone (T3) or with partial or predominant radiotherapy combined with tumorectomy without axillary dissection (T1 or T2). The results, normalized at 10 years, confirmed that the survival rate (crude or NED) was exactly the same as with other conservative treatments or mutilating surgical treatments. Relapses were few (8%) in T1 cases and acceptable in T2 and T3 cases (13% and 18% respectively); in almost every patient they were amenable to surgery, with good local postoperative course.

Locoregional recurrences following radical external beam irradiation and interstitial implantation for operable breast cancer--a twenty three year experience.

Locoregional recurrences are reported in 493 consecutive with T1 T2 N0 N1 breast cancer patients who were treated with radical external beam irradiation and interstitial 192 Ir. implant between 1961 and 1979. Follow-up ranges from 5-23 years (mean 10 years) with 195 patients having 10-23 years follow up (mean 12 years).

[Anatomical study of the kidneys of newborn infants dying after a septic state].

Over a 6 years period, 51 autopsies have been performed in infants dead after severe sepsis. One third of them had renal damages, consisting mainly in haemorrhagic infiltration. Pathological and clinical data are not always well correlated, but some parameters may enhance a poorer renal prognosis, such as the duration of shock and anuria, or exchange transfusion.

Effect of activity on the selective stabilization of the motor innervation of fast muscle posterior latissimus dorsi from chick embryo.

The role of neuromuscular activity in the maturation of the motor innervation was investigated in the fast focally innervated posterior latissimus dorsi (PLD) muscle of the chick embryo. The axonal supply in the PLD motor nerve, and the focal multiple innervation of the endplates were described on days 15 and 16 of embryonic life in normal and experimental embryos. In the first series of experiments, chick embryos were paralyzed by repeated injections between days 4 and 10 in ovo of the curare-like agent, flaxedil.

The possible role of radiotherapy in chronic lymphocytic leukaemia: a critical review.

The few clinical studies which have utilized irradiation as a treatment modality for chronic lymphocytic leukaemia (CLL) during the last two decades have led to rather conflicting and sometimes disappointing results. Low-dose total body irradiation (TBI) and extracorporeal, or mediastinal, radiotherapy did not appear to be superior to chemotherapy in most trials. Only the fractionated low-dose (600-800 rad) splenic irradiation was found to induce a long-lasting decrease of the lymphocyte count and a decrease in bone marrow infiltration in a significant proportion of cases, without any noticeable haematological toxicity.
