Single oral, subcutaneous or intravenous administration to mice and rats and oral administration to dogs were performed to investigate the acute toxicity of FUT-187. 1) LD50 values in mice were 4,395 mg/kg for males and 3,626 mg/kg for females orally, 6,284 mg/kg for males and 5,492 mg/kg for females subcutaneously, and 39.4 mg/kg for males and 41.4 mg/kg for females intravenously. In rats, these values were 4,653 mg/kg for males and 3,761 mg/kg for females orally, 6,799 mg/kg for males and 3,343 mg/kg for the females subcutaneously and 21.8 mg/kg for males and 15.8 mg/kg for females intravenously. 2) Death occurred 2 hours after administration in a male dog of the 3,000 mg/kg group just after convulsion and nasal discharge were observed. 3) General symptoms in mice and rats included a creeping gait, convulsion, singultus, cyanosis, decreased locomotor activity, piloerection and salivation which were commonly observed by all routes. All dogs showed vomiting and decreased locomotor activity; the prone or lateral position, crouching, ataxic gait and salivation were also observed in many cases. 4) On autopsy, changes attributable to local irritation by FUT-187 were seen in all species except mice and rats dosed intravenously. For the gastro intestinal-tract (GIT), inflammation of the stomach, adhesions between the stomach and the liver and sclerosis, petechiae or ulcer were observed in mice and rats dosed orally. In the subcutaneous route, retention of the test compound and necrosis at the injection site were observed. Reddening and loss of mucosal smoothness were observed in the GIT of a dog which died; desquamation, congestion, hemorrhage and retention of tested compound in the digestive mucosa were observed on histopathology.

Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.

A sporadic event of myotonia congenita in a infant admitted to the Paediatric Clinic for frequent crises of apnoea, cyanosis, vomiting and difficult feeding is reported. EMG analysis was consistent with the dominant variety of myotonia congenita. Mexiletine therapy showed excellent results in reducing myotonic activity. It is worthwhile stressing that early symptoms may go unnoticed or may be misinterpreted and that information on the genetic form of the disease can be obtained also from the EMG analysis through a repetitive stimulation test.

A 56-year-old woman was hospitalized because of jaundice, vomiting, and weight loss. Diagnostic measures were almost all negative except for computer tomography of the abdomen, which revealed a cyst in the pancreas. During performance of a diagnostic laparotomy the patient suddenly died, presenting with cyanosis and untreatable circulatory failure with a markedly elevated central venous pressure. Autopsy revealed pulmonary tumor-cell embolization. This rare cause of sudden death is characterized by the discrepancy between the clinical picture and the virtually negative preoperative diagnostic results. We present this case report as a reminder of this clinical entity and recommend an autopsy in every case of unexpected death under anesthesia.

Symptoms and signs were recorded for 1007 infants younger than 6 months of age seen at home (298) or hospital (709) and correlated with four grades of illness severity. Most symptoms, present in the preceding 3 days, were associated with all grades of illness. Only four symptoms were not reported in well infants: a fluid intake less than a third of normal, convulsions, frank blood in the stools, and bile-stained vomiting. By comparison, many signs were seen only in ill infants. Those associated only with moderate or serous illness were marked retraction of the lower ribs, high-pitched or moaning cry, expiratory grunt, loss of alertness, central cyanosis, and severe hypotonia. Although these will not identify all seriously ill infants, parents and professionals should be taught to recognize these important symptoms and signs of serious illness.

Emergency physicians frequently perform painful but necessary procedures on frightened children. We conducted a prospective, uncontrolled clinical trial of ketamine sedation (4 mg/kg IM) to facilitate a variety of procedures in 108 children aged 14 months to 13 years. Acceptable conditions were achieved with a single injection in 97% of the patients, and adjunctive restraint or local anesthesia was not required in 86%. Full sedation was produced within five minutes in 83%. Mean duration from injection to dischargeable recovery was 82 minutes (range, 30 to 175 minutes). One 18-month-old child vomited shortly after injection and experienced transient laryngospasm with cyanosis; intubation was not required, and there were no adverse sequelae. Airway patency and independent respirations were fully maintained in all other patients; no hemodynamic instability occurred at any time. There were no other clinically significant complications. Emesis well into the recovery phase was noted in 6% of the patients. Nightmares were not observed. Response from parents and physicians was strongly positive. Ketamine can be effectively used by emergency physicians to facilitate procedural sedation, yet equipment and expertise for advanced airway management are mandatory due to the rare occurrence of laryngospasm.

The sedative effects of medetomidine at doses of 20 and 40 micrograms/kg im given alone or followed 16-18 min later by fentanyl (2 micrograms/kg iv) was investigated in 6 bitches of mixed breeds. The higher dose of medetomidine alone caused the greater degree of sedation, but two bitches were only lightly sedated with either dose. Side effects noted in some cases included apparent pain on injection, vomiting on induction of sedation, bradycardia, slowing of respiratory rate, cyanosis and muscular twitching. The intravenous injection of fentanyl caused a marked increase in depth of sedation in all animals, inducing a condition similar to neuroleptanaesthesia in which the eyes were rotated downward and the pedal reflex abolished. Slight twitching and sensitivity to sound occurred immediately after fentanyl injection, but this was transient. The cardiopulmonary effects of medetomidine (40 micrograms/kg im) followed 20 min later by either fentanyl (2 micrograms/kg iv) or a saline placebo were investigated in 4 beagle dogs. Medetomidine caused bradycardia, hypotension and reduced respiratory rate, inducing an intermittent respiratory pattern. The iv injection of fentanyl did not further alter the heart or respiratory rate or blood pressure. However there was a small but significant decrease in arterial oxygen tension and rise in arterial carbon dioxide tension. indicating some respiratory depression. We conclude that the use of intravenous fentanyl to dogs already sedated with medetomidine could prove useful in clinical cases where the initial sedation with medetomidine has proved inadequate.

Among various cases of intracranial hemorrhage in the newborn caused by birth injury, posterior fossa subdural hematoma is of serious nature in many cases and often results in death after critical clinical course due to compression of the respiratory center of the medulla oblongata. We have recently experienced two cases of subdural hematoma in the posterior fossa caused by birth injury, which we successfully treated non-surgically. Herein, we report these two cases and present a sequential CT scan of each. The first case is a full-term (39 weeks gestation) male infant. Delivery was carried out spontaneously with double footling presentation. At 20 hours of age, cyanosis and convulsion occurred. CT scan was performed and revealed high density areas in the posterior fossa, quadrigeminal cistern and longitudinal cerebral fissure. Bloody CSF was discharged per lumbar puncture and glycerol was infused intravenously, but the ventricle became enlarged. At this point at 9 days of age, the infant was admitted to our hospital. While he showed poor activity on admission, hematoma was absorbed gradually and disappeared at 3 months of age by conservative treatment. Now, at 6 years and 6 months of age, the patient has no neurological deficits. The second case is a full-term (40 weeks gestation) twin female infant. Due to breech presentation, delivery was conducted per breech extraction. At three days of age, vomiting, fontanel bulging and hypotonia were observed. CT scan revealed hematoma similar to that seen in the first case, and steroid and glycerol were infused intravenously. Conservative treatment was performed in this case also, and changes shown by CT scan were almost the same as those seen in the first case. The patient has no neurological deficits at 5 years and 7 months of age. Since the introduction of CT scan, early diagnosis of a subdural hematoma in the posterior fossa has been possible. But reports of successful surgical treatment are not so frequent.(ABSTRACT TRUNCATED AT 250 WORDS)

This paper reports a one-month-old female with a one-week history of low grade fever and rhinorrhea, and one day of intermittent cough and cyanosis. The signs and symptoms are typical for pertussis in an infant less than six months old. The incidence of pertussis in the neonate and infant appears to be increasing. The disease still carries significant morbidity and mortality, especially in this age group. Pertussis should be included in the differential diagnosis of protracted cough with cyanosis or vomiting, persistent rhinorrhea, and marked lymphocytosis in children under six months of age.

The interest in mountain tracking and climbing has increased and there is a need for knowledge of altitude-related diseases. About one million non-acclimatized individuals annually frequent areas around 2,000 to 3,000 m above sea level and incur unpleasant symptoms in the form of acute altitude sickness or potentially fatal conditions such as pulmonary and/or cerebral oedema. Headache is the most prominent sign of acute altitude sickness but fainting fits, loss of appetite, hesitant gait, euphoria, or confusion also occur. Dyspnoea, cyanosis at rest, and a dry cough are signs of pulmonary oedema. Cerebral oedema may be feared when inexperienced climbers are afflicted by severe headaches, vomiting, and hesitant gait. Coma ensues relatively soon. Treatment consisting in descent to lower altitude, administration of oxygen, and possible medicinal therapy is effective if immediately introduced.
