An operant procedure to teach an echolalic, autistic child to answer questions appropriately.

An operant conditioning procedure to teach an autistic patient with rapid immediate echolalia to answer questions correctly was devised. The procedure involved positively reinforcing the patient immediately after a correct response and preventing incorrect responses. It is simple to implement and eliminates some of the structure and constraints inherent in previously described operant methods. This allows the procedure to be administered by a variety of therapeutic personnel and parents and in a variety of living situations.

Nodular fasciitis.

The case of a highly unusual lesion present in the mandibular area is reported. Operative intervention was successful, and healing was uneventful. The pathologic diagnosis was difficult to make because of the nature of the lesion.

Sudden cold water immersion.

Cold water is known to facilitate the drowning process. To gather information on the possible relationship between ventilation and cold stimuli, measurements of inspired and expired breath by breath ventilation and alveolar PCO2 were made on 8 male subjects suddenly immersed in both cold (11 degrees C) and warm water (28 degrees C). The mean ventilation for all subjects for the 1st three breaths following cold water immersion was 94.5, 71.3 and 94.6 L/min (BTPS) as compared to 60.0, 36.2 and 38.5 L/min (BTPS) for warm water immersion. Alveolar CO2 fell dramatically in cold water from a pre-immersion mean value of 36.4 torr to 23.9 torr, whereas there was only a change associated with the first few breaths following immersion in warm water. In prolonged cold exposure, ventilation was still markedly above that observed in warm water after 5 min. There was no relationship between skin fold thickness and ventilatory response over the period studied. A large increase in ventilations is likely to result in inefficient swim stroke mechanics. This, combined with a high probability of inspiration of water, may contribute to death as a consequence of cold water exposure.

Correction of transposition of the great vessels with previous Baffes procedure.

Twenty-four patients with transposition of the great vessels who underwent a Baffes procedure in infancy were totally corrected by a modified Mustard procedure. There were three postoperative deaths and one major complication. All survivors have been followed from 2 to 8 yr and have done well except for one patient who required a tricuspid valve replacement because of tricuspid insufficiency. It is our conclusion that this group of patients can be corrected with a relatively low mortality and a favorable outcome.

Inhalation toxicology of automotive emissions as affected by an oxidation exhaust catalyst.

Preliminary data are given on the acute inhalation toxicology of automotive emissions as affected by an oxidation exhaust catalyst. The catalyst effectively reduced CO and HC in the exhause which apparently had an effect (at least in a closed exposure system) on oxidant and NO2 levels by altering the HC/NOx ratio. There was a resultant reduction in biological effects due to the exposure. The catalyst altered the type of particulate to one which probably contained sulfuric acid as a major component. No evidence was present in these acute exposures to suggest a toxic response due to the higher sulfate emissions or possible catalyst attrition products. The effects of long-term exposure have not yet been investigated.

Serious postextraction hemorrhage into the submandibular space: report of case.

A 47-year-old woman had a swelling in the floor of the mouth and in the submandibular area on the left side. About four hours earlier, a dentist had extracted the mandibular left second premolar and first molar. The rate and degree of the distension were alarming; the floor of the mouth was at a level with the incisal edges of the mandibular incisors. Five hours later, the floor of the mouth was elevated about 1 1/2 cm above the incisal edges of the teeth. Treatment of the patient and her unusual sensitivity to meperidine and promethazine that caused a depression into Cheyne-Stokes respiration and hypotension are described.

The cervical aortic arch.

Cervical aortic arch anomaly is a rare congenital entity. The aortic arch extends into the soft tissues of the neck before turning downward on itself to become the descending aorta. Nineteen cases have been previously reported in the world literature with one more presently in publication. We have collected six additional cases, in four of which the cervical arch was located on the left. Formerly the left cervical aortic arch was felt to be much less common than the right. It now appears that they have equal incidence. Four of our cases were also associated with cardiac anomalies, and this coincidence has not been previously reported.

[Pregnancy in teenagers (author's transl)].

In this study pregnancy, delivery and the newborn infant of 151 juvenile primiparas and 1034 adolescent primiparas were analyzed and were compared with a group of 3563 primiparas 21, 23 and 25 years of age. Regarding the obstetric history and the intrapartum period there was no increase incidence of complications among the young patients, however we found among the older women an increase in the incidence of operative deliveries. In the postpartum period it was noted that the young primiparas had a higher incidence of postpartum bleeding caused by atonia of the uterus and also an increased incidence of placental complications with a high rate of manual placental extraction and curettages. A positive correlation was found between premature birth and perinatal mortality and the younger the age of the mother. The newborn of the young mothers was also lighter and shorter at birth and had a higher incidence of malformations. This study has shown, that juvenile expectant mothers are a risk group for obstetricians and pediatricians.
