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.

Since 1986 250 patients have undergone selective posterior rhizotomy for spastic cerebral palsy at New York University Medical Center. Severe, perioperative complications were experienced by 15% of these patients and consisted of bronchospasm, aspiration pneumonia, urinary retention, ileus, sensory loss. Additionally, most of our patients had severe pain immediately after the surgery and nearly half had dysesthesias for up to 3 weeks. Long-term complications such as decreasing range of muscle movement and hip dislocation are now becoming apparent. This patient population must be viewed as having special risks attendant with surgery and particularly with selective posterior rhizotomy.

Many anesthesiologists prefer epidural anesthesia for cesarean section because of the potential risks of general anesthesia such as Mendelson's syndrome. For this indication, the local anesthetic of first choice is the long-acting substance bupivacaine. The aim of the following study was to determine maternal and neonatal plasma concentrations of bupivacaine 0.5% following epidural anesthesia for cesarean section in order to give critical statements about the systemic toxicity of the local anesthetic. MATERIALS and METHODS. Central venous blood samples were collected for bupivacaine analysis (gas chromatography) in 15 patients (Table 1) undergoing cesarean section with epidural anesthesia over a period of 60 min after injection of 14 to 23 ml bupivacaine 0.5%. Six of these patients had received the epidural anesthesia earlier to relieve labor pain. Before administering the anesthetic dose, a blood sample was taken to determine the baseline value. Immediately after cord clamping, blood sampling was done to determine bupivacaine concentrations in the umbilical artery and vein. Apgar scores and blood gases were also checked and compared with those of neonates born by cesarean section under general anesthesia. RESULTS. Ten to 15 min following epidural application of 70 to 115 mg bupivacaine (mean = 99 mg), peak plasma concentrations occurred (mean = 0.41 micrograms/ml) The maximum plasma level of 0.7 micrograms/ml bupivacaine was found in a patient who had received epidural anesthesia for pain relief during labor. In this case, the baseline bupivacaine level after several epidural injections (125 mg in 15 h) before the anesthetic dose for cesarean section was 0.2 micrograms/ml. Immediately after delivery the mean plasma bupivacaine concentrations in the umbilical vein and artery were 0.11 micrograms/ml and 0.07 micrograms/ml respectively. Apgar scores and blood gas analyses showed no significant difference between neonates born by cesarean section under regional or general anesthesia. DISCUSSION. Using bupivacaine 0.5% for epidural anesthesia for cesarean section, we found maternal and neonatal plasma concentrations of the local anesthetic far below the accepted threshold level for producing systemic toxic reactions. In contrast to others, we obtained good analgesia and sufficient motor blockade accompanied by low plasma levels. In our opinion, there is no need to use 0.75% bupivacaine, especially since peak plasma concentrations of more than 2 micrograms/ml occur shortly after its epidural administration.

We reported a 71-year-old male with lateral medullary syndrome presented acute respiratory arrest after ataxic respiration. The patient had experienced transient diplopia repeatedly for about 2 weeks and then the developed persistent diplopia and vertigo. On the third day he was admitted to our hospital because of neurological deterioration and aspiration pneumonia. He showed left Horner's sign and double vision. And he had sensory disturbances of pain and temperature in the left face and the right side of the body, left limb ataxia and truncal ataxia. He showed dysarthria, severe dysphagia and left mild central facial paresis, but no hemiparesis. This case was clinically considered to be a typical case of left lateral medullary syndrome. When he was admitted to our hospital, he showed hypoxia with hypercapnea in spite of no history of chronic obstructive pulmonary disease. This condition was considered to be a central alveolar hypoventilation. He had two episodes of sudden-onset respiratory arrest following ataxic respiration on the 4th and 5th days, but no cardiac arrest. He was supported his respiration by mechanical ventilation until he was able to breathe spontaneously on the 29th day. The 22nd day MRI disclosed high intensity area in the left lateral and dorso-medial medulla in T2-weighted image, and this lesion was 1.5 cm in length. Therefore this case was diagnosed medullary infarction. This case developed ipsilateral facial pain in chronic stage. Pain existed around the eye and in the cheek, and pain was like toothache and unbearable like thalamic pain.(ABSTRACT TRUNCATED AT 250 WORDS)

At the Cancer Control Agency of British Columbia, 483 patients with cancer of the esophagus and cardia were seen from 1970-1980. Four hundred and one out of 483 (83%) had tumors larger than 5 cm (T2) and in 288/483 (60%) the disease had extended beyond the esophageal wall (T3). The overall 5-year survival rate was only 9% for all patients treated by external irradiation. The 5-year survival for a selected group having esophagectomy was 20%. Most patients died of persistent cancer at the primary site (83%); the cause of death was aspiration pneumonia (82%) due to obstruction caused by the persistent cancer. Our most recent experience using intracavitary irradiation either prior to or after external irradiation in 211 patients has been safe and simple and preliminary analysis of treatment results suggests that it has improved the therapeutic ratio. The analysis of quality of life at 6 months following therapy as it relates to performance status, swallowing ability, weight, and pain indicated significant improvement in all of these parameters. Of 171 patients, 33% were still alive at 1 year, 26% at 2 years, and 19% at 3 years following treatment. Of 43 patients suitable for preoperative irradiation, only 26 patients were actually resected and 19 of them are still alive with no evidence of disease, 8 to 30 months. The rationale and technical aspects of the combined treatment are described in detail. Treatment results, complications and an outline for future programs based on this experience are also described.

To determine the need for prophylactic nasogastric decompression following laparotomy and the influence of cimetidine, 200 consecutive patients who underwent major abdominal procedures were prospectively randomized into one of four limbs: no tube-placebo; no tube-cimetidine; tube-placebo; and tube-cimetidine. Patients were evenly distributed among these groups with respect to age, sex, alcohol and tobacco use, previous operations, and types of operations. There was significantly longer time until passage of flatus, bowel movement, and cessation of intravenous fluids in the tube group (p less than 0.05). Duration of postoperative stay increased from 11.4 to 14.1 days in the intubated patients (p less than 0.05). There was also significantly more pain with and frequency of swallowing, and nose/throat discomfort in the tube group. Nasogastric tubes reduced the incidence of vomiting from 28 in the no-tube group to 10 in the tube group (p less than 0.05), but most had only one or two episodes. Cimetidine did not affect either the incidence of vomiting or the duration of intubation, but was associated with a significant increase in pneumonias (p less than 0.05). Five patients without tubes initially, and seven patients with tubes had to have them inserted or replaced for vomiting or abdominal distention, which occurred equally in the placebo and cimetidine limbs. There were no cases of aspiration pneumonia, gastric dilatation, or wound dehiscence in the trial, and the four anastomotic leaks were divided equally between the tube and no-tube groups. The results indicated that prophylactic decompression was unnecessary in most patients and associated with increased morbidity and delayed return of gastrointestinal function. Cimetidine lowered nasogastric output on the first postoperative day (p less than 0.05), but did not prevent vomiting.

Fifty consecutive patients with metastatic carcinoma who underwent cryohypophysectomy were studied. Of these, 26 had breast cancer, 19 had prostatic cancer, one had malignant melanoma, one had cancer of the kidney, and three had metastatic adenocarcinoma from an unknown primary tumour. After cryohypophysectomy, excellent pain relief was obtained in 48% of patients, good or acceptable pain relief was obtained in 40%, and poor or no relief in 12%. Two patients died: one of aspiration pneumonia and one of an unknown cerebral cause. Sixteen patients developed diabetes insipidus, of whom three required therapy with vasopressin; eight patients developed a cerebrospinal fluid leak, two of whom required surgical repair; and four patients developed meningitis, which resolved in three after antibiotic therapy. Results are compared with those from other published reports. Pain relief from cryohypophysectomy is surmised to be due to the production of endorphins, but no proof of this is available.

Four cases of pharyngeal trauma in cattle due to improper administration of oral medications are discussed. These cases presented for suspected gastro-intestinal disorders and anorexia. Physical findings included copious drooling of saliva, pharyngeal pain, extended head and neck, forestomach stasis, fever, dysphagia, and pneumonia. Diagnosis was made by manual examination of the oral cavity or endoscopy. Ancillary diagnostic aids included clinical pathology and radiography. Hemograms were consistent with infection, serum electrolytes were normal. Radiographs in 3 of 4 did reveal significant evidence of retropharyngeal cellulitis. The signs of dysphagia and forestomach dysfunction were explained by either a pain induced inhibition of swallowing and eructation or direct involvement of the vagus nerve itself in the retropharyngeal region. An additional consequence of laryngeal motor dysfunction was aspiration pneumonia. Response to treatment with broad spectrum antibiotics, analgesics and symptomatic supportive care over a 7 to 14 day period was good.

Familial dysautonomia, also known as Riley-Day syndrome, is a disorder of autonomic nervous system with an autosomal recessive mode of inheritance. Reduction and/or loss of unmyelinated and small myelinated fibers is found, as reduction of dopamine beta-hydroxylase in blood. The diagnosis is based on clinical features: diminished lacrimation, insensitivity to pain, poor temperature control, abolished deep tendon reflexes, postural hypotension, vomiting attacks, poor motor coordination, and mental retardation. The treatment is symptomatic and many children die during the first years of life, usually as a result of repeated aspiration pneumonia. We report the case of a 1 year-old child with familial dysautonomia.

We report a right-handed 62-year-old man with early onset familial parkinsonism. The patient was well until 24 years of the age when he noted an onset of resting tremor in his right hand. During the next four years, he noted rigidity, bradykinesia, and difficulty in walking. He was seen in another hospital at 28 years of the age, where he received left pallidotomy. Rigidity on the left side showed marked improvement. He received right pallidotomy at age 30 years. He developed right hemiplegia after this surgery. He was admitted to our hospital in March, 1983 when he was 51 years of the age. He was treated with levodopa but improvement was rather of minor degree. He was transferred to another hospital, but his motor disturbance progressed slowly, and was admitted again to our hospital in November 1990. He had 6 siblings 4 of whom including himself suffered from parkinsonism. No consanguinity was noted in parents. On admission, he appeared chronically ill but the general physical examination was unremarkable. Neurologic examination revealed an alert and mentally sound man. Hasegawa dementia scale was 28.5/32.5. Upward gaze was slightly restricted (3/5). Cranial nerve examination revealed oculogyric crisis, apraxia of eyelid opening, masked face, and small voice. He was able to stand with support; his posture showed left-ward leaning. He had right hemiparesis with moderate weakness. He showed marked bradykinesia and moderate rigidity in his left upper extremity. Fine postural tremor was noted in the left hand. Deep tendon reflexes were diminished in the upper extremities. No Babinski sign was noted. Pain sensation was somewhat diminished on the right side. Results of routine laboratory examination were unremarkable. Cranial CT scan revealed atrophy in the frontal lobe, particularly in the prefrontal area. In addition, MRI revealed T1-and-T2-low signal intensity lesions in the right ventral pallidal region and in the left ventrolateral thalamic-hypothalamic areas. He was treated with 600 mg of levodopa with benserazide and 22.5 mg of bromocriptine with mild to moderate improvement in his bradykinesia and rigidity. He was discharged in January 1991. His clinical course was complicated by intestinal obstruction in October, 1994. He was admitted to another hospital where he was operated on the obstruction on November 5, 1994. The sigmoid colon was markedly dilated but no mass was found. Postoperative course was uneventful until November 18, 1994 when he was found dead in his hospital room shortly after 4 am. The patient was discussed in neurological CPC, and the chief discussant arrived at the conclusion that the patient had young-onset familial Lewy body-negative parkinsonism. Opinions were divided between Lewy body-positive familial Parkinson's disease and Lewy body negative young onset parkinsonism. Postmortem examination revealed aspiration pneumonia, which appeared to be the cause of his death, in the right lung. Neuropathologic examination revealed loss of malanized neurons in the substantia nigra and the locus coeruleus. In the substantia nigra, neuronal loss was particularly severe in the ventrolateral area. No Lewy bodies were seen. The dorsal motor nucleus of the vagal nerve was well preserved. Stereotaxic lesions involved bilateral thalamic areas. This patient appears to represent a case of autosomal recessive juvenile parkinsonism (AR-JP). Early onset, superb response to levodopa, sleep effect, and easy development of dyskinesias and motor fluctuations characterize AR-JP. The reason why this patient did not show these clinical features is probably bilateral sterotaxic surgeries. Particularly, the second surgery was complicated by right hemiparesis. His siblings who developed parkinsonism showed typical clinical features of AR-JP.
