[Neurogenic pulmonary edema following a grand mal seizure: a case report].

A case of neurogenic pulmonary edema following a grand mal epileptic seizure is presented. This condition is rather rare and the exact pathophysiology remains unknown, but it is believed that the event may be related to transitional increase of intracranial pressure during seizure attack. Pulmonary edema may be a serious complication of epileptic seizure. Rapid recognition and management is very important since the prognosis depends on the severity of pulmonary edema and appropriate treatment.

When do children avoid backwards coreference?

This study investigated the claim that very young children avoid backwards coreference in their interpretation of sentences containing pronouns. Eighty-one children ranging in age from 3;1 to 8;0 and eight adults acted out four types of pronominal sentences. Cross-sectional data and individual response patterns reveal that children initially prefer internal coreference even when such a response is disallowed for structural reasons. Avoidance of backwards coreference appears to be a late developing phenomenon characteristic of six-year-olds. Adult response patterns, which are manifested by some very young children, emerge as the dominant pattern by age seven.

[Age and pulmonary function testing in predicting postoperative morbidity after thoracic surgery].

In order to evaluate whether age and pulmonary function testing may predict postoperative morbidity and mortality in the patients having received thoracic surgery, 203 patients were included in this study. Spirometry, flow volume curve, lung volume determination and arterial blood gas analysis were performed in all of them. Postoperative complications were classified into respiratory complications including pneumonia, purulent bronchitis, atelectasis, respiratory failure and so on; and non-respiratory complications including subcutaneous emphysema, internal bleeding, stump leakage, dysarrythmia and so on. Of the 117 patients over 65 years of age, 27 (23.1%) had postoperative respiratory complications, 27 (23.1%) had non-respiratory complications, and 7 (5.93%) expired postoperatively. Of the 86 patients under 65 years of age, 21 (24.4%) had postoperative respiratory complications and 9 (7.6%) had postoperative non-respiratory complications, but one expired. The incidences of postoperative mortality and non-respiratory complications were both higher in the patients over 65 years of age (p less than 0.05). Our results indicated that age is a risk factor of thoracic surgery, even if the pulmonary function testing meet the surgical criteria.

Pneumothorax following cytotoxic chemotherapy in malignant lymphoma.

Pneumothorax occurring as a complication of the antitumor effect of cytotoxic chemotherapy has been reported in occasional cases of a variety of tumors. Its occurrence in malignant lymphoma has not been reported heretofore. In this report, we describe two cases of this complication in patients with malignant lymphoma and discuss the possible pathophysiologic mechanisms involved. Because pulmonary involvement with the tumor was found in both cases, pneumothorax could be attributed to the anti-tumor effect of cytotoxic agents on underlying lung involvement in patients with malignant lymphoma.

Control and coreference in early child language.

This study investigated the relationship between control and coreference using an act-out task involving 81 children ranging in age from 3.1 to 8.0 and eight adults ranging in age from 30 to 55. The results replicated previous findings in revealing five developmental stages in children's interpretation of PRO, an empty pronominal element. A significant relationship was observed in the patterns of children's interpretation of forwards sentences containing PRO and those containing overt pronouns. However, there was no relationship in the development of restrictions on control and restrictions on coreference.

When-questions: a study of how children linguistically encode temporal information.

Sixty children between the ages of 4 and 7 years and 10 adults were presented with a series of stories illustrated by five pictures in a comic strip format. Each story was followed by either a "when-," "why-," or control question. With respect to the "when"-questions, some of the stories involved causally related events while others did not. An analysis of the responses supported the hypotheses that causal relationships play an important role in the development of the ability to encode temporal relationships in response to "when"-questions.
