The Northwest Regional Screening Program to detect congenital hypothyroidism in infants born in Oregon, Montana, Alaska, and Idaho (combined birthrate of 69,000/ yr) was added to our ongoing screening program in 1975. The program utilizes dried blood filter paper specimens collected routinely in the first few days of life in all four states and again at about 6 weeks of age in Oregon only. The screening test consist of an initial thyroxine (T4) measurement; a thyroid-stimulating hormore (TSH) determination is performed on those specimens with T4 concentrations in the lowest 3% group. Serum samples obtained by venipuncture are requested for confirmation of the diagnosis. In the first two years of the program, 25 infants with primary hypothyroidism were detected amont 110,667 infants screened, a frequency of 1:4,430. Fourteen cases of thyroxine-binding globulin deficiency were also detected, a frequency of 1:7,900. Using the T4 followed by TSH testing approach, the frequency of request for repeat specimens was 0.4% in Oregon and 0.05% in the other states. The cost per specimen was $1.96. The majority of infants lacked clinical signs or symptoms of hypothyroidism; only one infant was clinically suspected of having hypothyroidism prior to detection. The most common neonatal symptoms were constipation, lethargy, and prolonged jaundice, while the most common physical signs were hypotonia, umbilical hernia, and large fontanels. Thyroid scans showed the most common etiology to be thyroid aplasia, followed by an ectopic gland, hypoplasia, and goiter. Serum T4 concentrations were lowest in those infants with aplasia, intermediate in infants with an ectopic gland or hypoplasia, and normal in the infant with the goiter. Neonatal hypothyroidism varies in degree and has several different causes; the capacity to secrete thyroid hormone, the duration before hypothyroidism becomes clinically manifest, and possibly the eventual prognosis for intellectual function depend on the nature of the underlying cause. While the mean age at treatment was 59 days, the goal of diagnosing congenital hypothyroidism and treating affected infants by 1 month of age seems realistic.

Infant botulism is a unique neuromuscular disease affecting infants less than six months old. It is the result of intraintestinal toxin production by C. botulinum (toxi-infection). Characteristic symptoms include constipation, lethargy, and decreased feeding. Physical examination often reveals generalized hypotonia with cranial nerve impairment. Recovery is dependent on supportive care in an intensive care setting. The relationship of this disease to the sudden infant death syndrome requires further study.

Botulism is a serious intoxication caused by ingestion of food containing preformed botulinus toxin and characterized by rapidly progressive bulbar paralysis, generalized weakness, and respiratory insufficiency. In 1976 a distinct clinical entity of infant botulism was recognized. The disease apparently results from intraintestinal toxin production which produces a defect in neuromuscular transmission by interfering with release of acetylcholine at cholinergic synapses. Five cases of infant botulism were identified at the Children's Hospital of Philadelphia between 1975 and 1977. Initial symptoms included constipation, slow feeding, lethargy and weak cry. Four of the patients progressed to respiratory insufficiency requiring nasotracheal intubation. Three of the infants with respiratory failure required tracheotomy. Because infants with respiratory failure may require support for months, we recommend that a tracheotomy be performed early in the management to avoid the complications associated with prolonged intubation. The effectiveness of antitoxin or antibiotics to treat infant botulism remains questionable and therefore prolonged respiratory supportive care is the mainstay of therapy. In addition, we offer guidelines for decannulation in cases of infant botulism. None of the patients in our series could be decannulated prior to initial discharge from the hospital.

Hypothyroidism in patients with diabetes mellitus is usually primary though rarely secondary hypothyroidism has occurred. An 11 6/12 year old white female developed diabetes mellitus at 8 6/12 years of age. She received treatment up to 40 units NPH daily with adequate control and normal growth. Hypothyroidism was diagnosed after a 3 month history of lethargy, constipation, dryness of skin and decreasing insulin requirement to 10 units NPH per day. Physical examination was entirely normal, except for dry skin. Serum levels of free thyroxine, thyroxine, T3 resin uptake, were low as was 131I uptake. Primary hypothyroidism was ruled out by the absence of goitre, absent antithyroid antibodies, low basal TSH levels and increased 131I uptake after TSH administration. Serum TSH levels rose 4-fold in respone to intravenous TRH administration. The patient was treated with 0.15 mg daily of L-thyroxine with very good response. This report describes a patient with juvenile diabetes mellitus and isolated TSH deficiency with hypothyroidism of probably hypothalamic origin, an association not previously described in children.

During neurophysiologic studies in the rat [Crl:COBS CD(SD)BR], chloral hydrate was given intraperitoneally to produce anesthesia for brain electrode implantation. The incidental occurrence of adynamic ileus in six of these rats, 5-16 days after surgery, prompted further investigation. Pathological evaluations and transmission experiments using ingesta and viscera from affected rats failed to reveal an infectious agent. Subsequently chloral hydrate-induced adynamic ileus leading to morbidity or death was experimentally produced in 14 of 27 rats, 3--36 days after intraperitoneal administration of the anesthetic at a dose of 400 mg/kg body weight and concentrations of 125--275 mg/ml. The experimentally produced condition was characterized by lethargy, anorexia, abdominal distension, ruffled hair coat, inactivity, drowsy expression, constipation, and death. Gross pathologic findings included gaseous distension and atony of the cecum and segments of the small intestine. Small intestine contents varied from liquid to solid. The colon and rectum contained only a few dry hard fecal pellets. A few animals showed excess abdominal fluid. Microscopic findings were limited to focal chronic serositis and serosal fibrosis affecting the visceral peritoneum. On the basis of the experimental studies, it was concluded that the condition described was not an infectious disease but was an abnormal physiologic condition produced by the irritating or pharmacologic action of chloral hydrate given at high concentrations in the abdominal cavity.

A 2-year-old Tennessee Walking Horse colt was admitted for evaluation of signs of abdominal pain, inappetence, and constipation of 5 days' duration. Two days prior to the onset of signs, the owner had cut the sacrococcygeal muscles as part of a tail-setting procedure. On examination, the horse was febrile and lethargic, and intestinal sounds were not heard on auscultation. Results of peritoneal fluid analysis were indicative of peritonitis. The horse continued to deteriorate and died despite treatment with antimicrobials, flunixin meglumine, and balanced electrolyte solution. At necropsy, the peritoneal cavity contained approximately 20 L of serosanguineous fluid. One of the myotomy wounds was filled with yellow-green material that extended from the base of the tail along the ventrolateral aspect of the rectum and into the peritoneal cavity. Escherichia coli was isolated from the myotomy site and peritoneal fluid.

Congenital hypothyroid dwarfism was diagnosed in a family of Giant Schnauzers. Three female and two male puppies from different litters were evaluated for dwarfism, lethargy, somnolence, gait abnormalities, and constipation. On physical examination, disproportionate dwarfism (n = 5), macroglossia (n = 3), hypothermia (n = 3), delayed dental eruption (n = 3), ataxia (n = 2), and abdominal distension (n = 1) were identified. Results of initial laboratory tests showed anemia (n = 4), hypercholesterolemia (n = 4), hypercalcemia (n = 2), and transudative abdominal effusion (n = 1). Radiographic skeletal surveys disclosed epiphyseal dysgenesis and delayed skeletal maturation (n = 5). A diagnosis of hypothyroidism was established on the basis of low basal serum thyroxine concentrations that failed to increase following the administration of TSH (n = 5) and markedly reduced to absent thyroid image when evaluated with gamma camera imaging of the thyroid gland (n = 4). In the two dogs that were most thoroughly evaluated, the results of thyroid histology, prolonged TSH testing, and repeat thyroid imaging, after three daily injections of TSH, were all consistent with secondary or tertiary, rather than primary, hypothyroidism. When TSH was administered over a period of 3 consecutive days (5 IU/day, subcutaneously), serum thyroid hormone response became normal and resulted in a normal thyroid image in the two dogs re-evaluated with gamma camera imaging. Daily treatment with oral levothyroxine (20 micrograms/kg) resulted in complete remission in puppies (n = 4) treated prior to 4 months of age. The other puppy failed to attain normal breed standards for height.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of paraneoplastic encephalomyelitis and subacute pandysautonomia associated with an occult atypical carcinoid tumour of the lung is described. The main clinical features were lethargy, impaired memory, constipation, and orthostatic hypotension. Neurological investigation was unremarkable except for mononuclear pleocytosis and increased protein level in the cerebrospinal fluid (CSF). Tests of autonomic function revealed a low plasma norepinephrine level, a marked drop of blood pressure (BP) to vertical tilt and Valsalva maneuver, and a marked rise of BP to dilute norepinephrine infusion. A few days prior to death, the patient became hypothermic and had repeated episodes of respiratory arrest associated with transient atrioventricular block on the electrocardiogram (ECG). A polysomnographic study confirmed a sleep apnea syndrome. Autopsy revealed an atypical carcinoid tumour in one tracheobronchial lymph node, widespread lymphocytic infiltrates and loss of neurons in the cerebral, cerebellar and brainstem grey matter, the spinal cord and roots, and the paravertebral sympathetic ganglia as well as microglial and astrocytic proliferation in the central nervous system.

A 19-mo-old boy with cystic fibrosis presented with a lifelong history of feeding problems and constipation, and an 8-mo history of episodes of repeated retching, diaphoresis, dehydration, and somnolence after eating. Tests of esophageal motility and gastric emptying of a 5% glucose meal were normal. Antroduodenal pressure recordings during fasting demonstrated the presence of all phases of the interdigestive motor complex. After consumption of a 240-ml complex liquid meal, however, the contractile pattern that generally accompanies eating was absent and gastric emptying was markedly delayed. When bethanechol or metoclopramide was given 10 min before the complex liquid meal, there was a paucity of contractile activity, gastric emptying was slow, and symptoms of lethargy, diaphoresis, and retching were present. When cisapride was given, there was frequent irregular contractile activity, faster gastric emptying, and no symptoms of lethargy. During the past year treatment with cisapride has been a requirement in order to prevent recurrence of the symptoms. Antroduodenal pressure studies proved helpful in the identification of a treatable manometric abnormality that was associated with symptoms of delayed gastric emptying.

The authors report eight preterm infants with hypothyroxinemia who developed clinical features similar to those described in congenital hypothyroidism: prolonged jaundice, hypoactivity, lethargy, constipation, edema, and hoarse cry. All had low serum thyroxine, normal thyroid stimulating hormone, and normal thyroid binding globulin levels. After exclusion of other causes for the symptoms, thyroid replacement therapy was started, resulting in rapid resolution of symptoms and return to euthyroid status. Follow-up of these infants after cessation of therapy revealed normal growth and development and normal thyroid function. The authors therefore recommend a prospective study to investigate the incidence of hypothyroxinemia, frequency of associated clinical features, and the benefits of thyroid replacement therapy based on a randomized controlled trial.
