An assessment of morbidity in near-drowning was made from a review of emergency room and hospital records of 72 patients, ages 9 months to 20 years, who suffered near-drowning during the period January 1972 through June 1974. Fifteen patients (21% evidenced severe anoxic encephalopathy; the remainder had no detectable neurologic deficits. Hypoxemia was demonstrated in 56 patients. Severe acidosis was not present unless respiratory failure occurred. Neither electrolytes, red blood cell hemolysis, nor cardiac arrhythmias presented a problem. Respiratory complications included pulmonary edema, aspiration pneumonia, atelectasis, shock lung, pneumothorax, and pneumomediastinum. All children requiring cardiopulmonary resuscitation in the emergency room suffered anoxic encephalopathy. The occurrence of seizures, fixed and dilated pupils, flaccid extremities, and lack of response to deep pain in the emergency room had almost universal correlation with resultant severe anoxic encephalopathy, as did a submersion period of six or more minutes. The morbidity of near-drowning is significant with regard to the number of children affected and the severity of the central nervous system insult received. The statement by the American Heart Association that resuscitative efforts in children should be continued for periods longer than ten minutes needs reevaluation, since neurologic recovery did not occur in any child requiring cardiopulmonary resuscitation (CPR) in the emergency room. More importantly, new methods of cerebral resuscitation need to be developed and established. In short, medical personnel need to think in terms of cardiopulmonary cerebral resuscitation (CPCR) rather than in terms of CPR.

Pharmacologic management of peptic ulcer disease continues to evolve with the introduction of diverse types of new therapeutic agents. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer, and delay ulcer recurrence. This article provides a broad perspective on the pharmacology and therapeutic actions of antiulcer drugs. To date, no drug meets all goals of therapy. Drug treatment of peptic ulcers is targeted at either counteracting aggressive factors or stimulating the mucosal defense. Drugs that inhibit or neutralize gastric acid secretion include histamine H2-receptor antagonists, proton pump inhibitors, anticholinergics, prostaglandins, and antacids. H2-receptor antagonists have become first-line drugs for treatment of uncomplicated duodenal ulcers, gastric ulcers, prevention of ulcer relapse, and mild esophagitis. However, H2-receptor antagonists, like other gastric antisecretory/antiulcer drugs, have high rates of ulcer recurrence following discontinuation of therapy. They therefore need to be administered continuously in patients prone to such recurrences. Omeprazole has emerged as a major drug for the treatment of severe erosive esophagitis, refractory ulcers, and Zollinger-Ellison syndrome. The major disadvantage of proton pump inhibitors is the concern for their long-term safety. The roles of M1-antimuscarinic agents and antacids have not been fully defined. Misoprostol, effective for the treatment of gastric and duodenal ulcers, is now the only drug that prevents ulcers induced by nonsteroidal anti-inflammatory drugs. Mucosal protective drugs that do not inhibit gastric acid secretion include sucralfate and organic bismuth salts. Sucralfate is a nonsystemic, well-tolerated, effective drug for treatment of duodenal ulcers and prevention of duodenal ulcer relapse. The organic bismuth salt bismuth subcitrate is efficacious in the treatment of duodenal and gastric ulcers. Furthermore, it has also been established that it alters the course of ulcer recurrence. However, bismuth encephalopathy is a major toxicity concern that needs to be addressed.(ABSTRACT TRUNCATED AT 250 WORDS)

We analysed 98 consecutive instrumental rotational deliveries of babies weighing > 2,500 grams in primiparae. Our aim was to compare the use of Kjelland's forceps with vacuum delivery with regard to efficacy and safety. The vaginal delivery rate was similar with Kjelland's forceps (96%) and vacuum (90%). The vacuum cup failed to effect rotation in 14% and 77% required forceps delivery after vacuum rotation. The vacuum took longer to effect delivery (P < 0.01). Women delivered with Kjelland's forceps had higher pain scores in the puerperium. There were no perinatal deaths. Low Apgar scores and cord arterial pH values of less than 7.20 were recorded more frequently after vacuum rotation (p < 0.05). Babies delivered with Kjelland's forceps sustained more physical trauma. The incidence of asphyxial encephalopathy was the same in both groups. We would recommend a more selective approach to the use of both rotational vacuum and Kjelland's forceps in primiparae.

To ascertain the range of neurological problems in patients with systemic cancer, we prospectively evaluated neurological symptoms, neurological diagnoses, and primary tumors in all patients with a history of systemic cancer examined by the Department of Neurology at the Memorial Sloan-Kettering Cancer Center, from Jul 1, 1990, to Dec 31, 1990. Of the 815 patients seen for neurological symptoms, less than half (45.2%) had metastatic involvement of the nervous system. The three most common symptoms were back pain (18.2%), altered mental status (17.1%), and headache (15.4%). The most common neurological diagnosis was brain metastasis (15.9%), followed by metabolic encephalopathy (10.2%), pain associated with bone metastases only (9.9%), and epidural extension or metastasis of tumor (8.4%). Of 133 patients with undiagnosed back or neck pain, 44 (33%) had epidural extension or metastases from tumor and 40 (30%) had pain associated with vertebral metastases only. In 15 (11%) the cause for the back pain was unrelated to metastatic disease. Of 132 patients seen on initial consultation for altered mental status, metabolic encephalopathy was the major neurological diagnosis (80; 61%); 20 (15%) had intracranial metastases. Of 97 patients with undiagnosed headache, 59 (61%) had a nonstructural cause. Fifty-three of these patients had either migraine, tension headache, or headache related to systemic illness (e.g., fever, sepsis). These results indicate that even in patients with systemic cancer, a group particularly prone to developing neurological disease that can be diagnosed radiologically, the role of clinicians remains important in helping distinguish noncancer-related and nonmetastatic neurological problems.

To identify cortical and subcortical structures in the brain which are associated with septic encephalopathy, local cerebral glucose utilization (LCGU) in the 31 discrete regions were evaluated with a quantitative (14C)-2.deoxyglucose autoradiographic method in the septic rat model. Sepsis was produced by cecal ligation and punctures. Forty rats were subjected to behavioral study and divided into two groups (control, n = 15; sepsis, n = 25). Septic rats died within 36 h, and the rats developed behavioral depression, and showed EEG slowing and an increase in pain threshold. The latter was evaluated by a tail flick method within 8 h after the surgical procedures, while control rats did not show significant change in either behaviors or pain threshold. In another study, LCGU was measured when behavioral depression, increase in pain threshold, and EEG slowing developed in the sepsis group (n = 7). In this group, the mean LCGU in auditory and parietal cortices, lateral geniculate, superior colliculus, hippocampus, and locus ceruleus was 95, 74, 67, 69, 72, and 53 mumol.100 g-1.min-1, being lower by 23%, 22%, 18%, 19%, 14%, and 27% than that in the sham-operated control group (n = 7), respectively. However, the mean LCGU in septal and raphe nuclei was 52 and 84 mumol.100 g-1.min-1, being significantly higher by 27% and 33% than that in the control group, respectively. These results suggest that septic encephalopathy is associated with metabolic changes in the discrete brain regions, which are related to the serotonergic or noradrenergic system.

Although the conventional Bordetella pertussis vaccine, which consists of killed whole organisms, has been shown to be effective in preventing disease, it has been associated with transient local and systemic reactions and may produce encephalopathy, though rarely. A new acellular pertussis vaccine containing partially purified protein antigens, filamentous hemagglutinin, and lymphocytosis-promoting factor hemagglutinin has been developed for use in Japan. We compared the immunogenicity and reactogenicity of conventional and acellular pertussis vaccine. Forty children aged 4 to 6 years and 40 children aged 18 to 24 months, all previously immunized at appropriate times with conventional diphtheria and tetanus toxoids and pertussis vaccine, were enrolled. We randomly assigned children to receive either conventional pertussis vaccine or acellular pertussis vaccine in a double-blind fashion. The diphtheria and tetanus components in both preparations were identical. Equivalent rises in pertussis agglutinin titers and antibodies to filamentous hemagglutinin and lymphocytosis-promoting factor hemagglutinin were measured in both vaccine groups at both ages that we studied. However, reaction rates to the two vaccines in both age groups were strikingly different. Acellular pertussis vaccine was significantly less reactogenic for fever, pain, fretfulness, abnormal gait, and local reactions at the vaccine administration site. If studies in progressively younger children confirm its reduced reactogenicity and equal immunogenicity, and if large-scale trials indicate its efficacy, the acellular pertussis vaccine may be a more appropriate candidate than the current vaccine.

Lyme disease typically begins with a unique skin lesion, erythema chronicum migrans (ECM) (stage 1). Patients with this lesion may also have headache, meningeal irritation, mild encephalopathy, multiple annular secondary lesions, malar or urticarial rash, generalized lymphadenopathy and splenomegaly, migratory musculoskeletal pain, hepatitis, sore throat, non-productive cough, conjunctivitis, periorbital edema, or testicular swelling. After a few weeks to months (stage 2), about 15% of patients develop frank neurologic abnormalities, including meningitis, encephalitis, cranial neuritis (including bilateral facial palsy), motor or sensory radiculoneuritis, mononeuritis multiplex, or myelitis. At this time, about 8% of patients develop cardiac involvement--AV block, acute myopericarditis, cardiomegaly, or pancarditis. Throughout this stage, many patients continue to experience migratory musculoskeletal pain in joints, tendons, bursae, muscle, or bone. Months to years after disease onset (stage 3), about 60% of patients develop frank arthritis, which may be intermittent or chronic. Recently evidence suggests that Lyme disease may also be associated with chronic neurologic or skin involvement. Thus, Lyme disease occurs in stages with different clinical manifestations at each stage, but the course of the illness in each patient is highly variable.

In bad cases of whiplash injury of the cervical spine the post-accidental course is complicated by pain, vegetative dysfunctional syndromes and by psychic and psychiatric disorders over many years. There is no satisfactory concept to understand the pathophysiology of these processes. The paper deals with the possibility of a reflex dystrophy. Sympathetic reflex dystrophy syndromes are seen principally in patients with joint, tendon or vascular lesions. In case of whiplash injury, it would concern the cervical spine itself as well as visceral organs including the central nervous system. For the CNS the lymphostatic encephalopathy is a well defined entity. Above all, a reflex dystrophy develops on the basis of a special personality structure. In case of psychic and psychiatric complaints after whiplash injury patients with a so called Sudeck-personality should not be suspected to aggravate; in contrast, especially in these patients complications by reflex dystrophy are credible. Consequences for the assessment and for rehabilitation are discussed.
