A newborn, whose mother had been treated with lithium carbonate for a manic-depressive illness suffered from hypotonia, poor feeding, weak Moro reflex, hyperexcitability, thyroid enlargement and cyanosis. Symptoms resolved within a few weeks. No malformations could be detected. The psychomotor development of the child was normal up to the age of 18 months.

Fifty-eight children with laryngotracheobronchitis (LTB) were studied. Many were malnourished, or in the post-measles state, or had some lower respiratory tract or cardiac involvement. In these patients, factors helpful in assessing the need for relief of airway obstruction by tracheal intubation have been evaluated. A set of indications for intubation, which includes clinical and arterial blood gas features of LTB is suggested. Cognisance of complications of disease, where present, has also been taken. If cyanosis or muscular hypotonia or unawareness is present, intubation is urgently needed. When two of the following occur together, the need for intubation has arisen: (a) pulse rate greater than 170/min and respiratory rate greater than 55/min; (b) paCO2 greater than 37 mmHg; (c) paO2 less than 50 mmHg; and (d) a complication (cardiac failure or severe lower respiratory tract infection).

The case is described of a neonate who suffered from withdrawal symptoms within 24 hours after birth as a result of the use of clomipramine by the mother during pregnancy. The symptoms consisted of increased irritability, alternating hyper- en hypotonia, hyperreflexia, cyanosis and hypothermia. He was treated with clonazepam with good result. Prescription of clomipramine during pregnancy should be restricted to specific cases and the doses should be kept as low as possible. Because the symptoms are withdrawal symptoms, phenobarbital should not be used as treatment, as it increases drug metabolism by the liver causing an even faster decrease of plasma concentrations of clomipramine. Clonazepam is the drug of choice.

The familial transmission risk of developing bipolar disorder for first=degree relatives of the patient is 1.5-10.2%, however, the risk of any affective primary disorder is 15-20% in such relatives. Pregnancy places additional stress on patients, and physiological changes are particularly acute during postpartum. The risk of abnormalities and teratogenicity from psychotropic drugs is significant: taking of phenothiazines, tricyclic antidepressants, monoamine oxidase inhibitors, benzodiazepines, lithium, valproate, and clonazepam require extreme caution. In 225 pregnancies exposed to lithium in the 1st trimester congenital malformations occurred in 11%. Premature birth and macrosomia may also increase, thus halting lithium well before planned conception with weekly serum monitoring is advised. Recurrence of the illness can be managed by electroconvulsive therapy. About 40% of patients can experience postpartum mania or depression. Taking drugs up to delivery can result in behavioral teratogenesis in the neonate even in the absence of physical malformations. Lithium toxicity causes lethargy, hypotonia, tachycardia, coma, cyanosis, and chronic twitching in the newborn. Breast feeding is discouraged in women taking lithium because of the high rate of transmission to the infant. The stress of parenting can also trigger relapses of the disease. The deleterious effect of a manic or depressive mother on the child's development is manifested in criticism and stressing achievement often leads to low self-esteem. It behooves the psychiatrist to frankly reveal the risks of pregnancy to couples who wish to have a child or to advise about the pregnancy to term so they can make an informed decision.

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.

From January 1984 through August 1986, 130 infants were referred to our department with a history of apnea, hypotonia, and cyanosis or pallor, suggesting near-miss sudden infant death syndrome. Protocol consisted of medical history, clinical examination, overnight polygraphic recording, and cardiologic, gastrointestinal, metabolic, neurologic, and toxicologic workups. In 49 of these infants who needed vigorous stimulation or mouth to mouth resuscitation, the event occurred shortly after feeding. Combined, continuous esophageal pH monitoring and polygraphic recording in these 49 infants showed pathologic gastroesophageal reflux (GER) in 34 patients. An abnormal overnight polygraphic recording was observed in 8 of 34 infants with pathologic GER. Other investigations led to etiologic diagnoses in 42 of the remaining infants. Severe GER was frequently found in children with apnea after feeding but clearly is not the only mechanism involved. Infants with a history of apnea after a feeding should be investigated for GER and appropriately treated.

Two cases of cervical myelopathy, which exhibited peculiar vasomotor symptoms ("acro-erythro-cyanosis") on distal regions of the four limbs are reported. Continuous reddening, swelling and skin temperature increase were observed on both hands and feet in case 1, a-44-year-old man, and on both hands in case 2, a-47-year-old man. Cold stimulation resulted in cyanosis and decrease of skin temperature on the affected regions paroxysmally. The condition of skin at room temperature may be caused by arteriectasia of arterioles due to hypotonia of vasomotor fibers, and this was similar to erythromelalgia. On the other hand, cold stimulation may have led to this condition, where the contraction of skin arterioles due to hypertonia of vasomotor fibers was added to the dilation of venule, and this was similar to acrocyanosis. Consequently, we provisionally named the vasomotor symptoms in the present cases as "acro-erythro-cyanosis". The other neurological signs were as follows. Case 1: mild weakness in right upper and lower limbs and left small hand muscles, mild superficial and deep sensory disturbance on bilateral palms and soles and decrease of vibration on bilateral lumbar regions and thereunder. Case 2: mild weakness of right small hand muscles, superficial sensory disturbance on distal regions of bilateral upper and lower limbs and a decrease of joint position sense on right hand. Myelography and metrizamide CT myelography revealed a high-degree deformity of the spinal cord due to the herniated disks between C4 and C5 in case 1 and between C3 and C4 in case 2.(ABSTRACT TRUNCATED AT 250 WORDS)

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)

A 3-day-old girl had a syndrome of lethargy and lactic acidosis. Pregnancy and delivery had been normal; there was no consanguinity or family history of neuromuscular disease. At age 4 1/2 months, she had generalized weakness, hypotonia, areflexia, and macroglossia. She developed cyanosis and respiratory failure, and marked cardiomegaly was noted. She died at age 8 1/2 months of cardiac arrest. Results from a muscle biopsy specimen obtained at age 4 1/2 months showed ragged-red fibers and increased glycogen and lipid droplets. With the cytochrome c oxidase reaction, only 5% of the fibers stained positively in the biopsy specimen. Cytochrome c oxidase activity was 7.3% of normal in muscle mitochondria and 12.2% of normal in heart mitochondria. Reduced-minus-oxidized cytochrome spectra showed lack of the cytochrome aa3 peak. Immunotitration using antibodies against purified human heart cytochrome c oxidase showed normal amount of cross-reacting material in both heart and muscle. The genetic error could have involved a cytochrome c oxidase isozyme common to heart and muscle.

We describe a neurologically compromised infant with tetralogy of Fallot who was having multiple paroxysmal episodes of hypotonia, eye rolling, stiffening, and loss of consciousness. Simultaneous electroencephalography with video monitoring was used to determine if these episodes were a primary epileptic phenomenon or the result of hypoxic central nervous system involvement from paroxysms of hyperpnea and cyanosis. The findings would suggest that the paroxysmal episodes were not primarily epileptic. The electroencephalographic findings during the spell were similar to those found with hypoxia due to other causes. This may have physiological and therapeutic significance and be useful in following other infants with congenital heart disease who have similar episodes, especially when the infants have significant risk factors for seizures.
