Ten clinically intact weaned piglets were experimentally intoxicated by intravenous injection of lipoproteide-free lipopolysaccharide endotoxin according to Westphal of E. coli O 127:B8. Severe endotoxin shock with all clinical manifestations of experimental coli-enterotoxaemia was induced in all animals and included circulatory disorder with tachycardia, intermittent pallor and/or cyanosis, symptoms of severe systemic intoxication, neurological symptoms, such as lack of coordination, hindleg staggering, spasm, paresis, paralysis, changes in respiration, such as rise in respiratory frequency and deepened breathing premortal deceleration of respiration and gasping for breath, temperature, variation, including hyperthermia and aggravating hypothermia, gastro-intestinal symptoms, such as temporary vomiting and persistent diarrhoea, leucopenia, eosinopenia, variation of haematocrit, edematisation, increased transudation, congestion, and gastro-intestinal shock lesions. Eight animals died. These experiments quite obviously have confirmed that endotoxin shock is the common pathogenetic principle behind all forms of coli-entertoxaemia (i.e, the forms of edematisation, cardiovascular failure, and gastro-intestinal processes.) Lipopolysaccharide endotoxin alone may be responsible for the development of both edemas and neurotoxic symptoms (edema disease) and diarrhoea (gastro-intestinal form of coli-enterotoxaemia). The pathogenetic relevance of additional toxins (neurotoxin and enterotoxin) is discussed under this aspect.

Ingestion of marijuana by three dogs in unrelated incidents resulted in depression-type toxicosis in each case. The most evident clinical signs were central nervous system depression and ataxia. Emesis and hypothermia were noted in two of the cases. Symptomatic and supportive treatment was accompanied by clinical improvement. In two cases, recovery was slow, with clinical signs apparent for 36 to 48 hours after onset. In the third case, clinical signs were apparent for only 3 hours.

A new case of propionic acidemia is presented, paying special attention to the early symptoms of this disease, such as increased drowsiness, muscular hypotonia, poor feeding, hypothermia, metabolic acidosis, ketonuria and vomiting. Investigation by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) revealed the excretion of fairly high amounts of 2-methyl-3-oxovaleric acid, a condensation product of two molecules of propionyl-CoA, as well as the known pathological metabolites such as propionic, 3-hydroxypropionic and methylcitric acids. Among the post mortem findings the histological studies of the liver were the most remarkable.

1 The hypothermia produced by intraventricular injections of thyrotropin releasing hormone (TRH) in unanaesthetized cats has been investigated. 2 TRH is more potent than either noradrenaline or calcium ions. It is estimated that the equi-potent molar ratio for TRH: noradrenaline:calcium is 1:900:27,000. 3 TRH injections is also produce profuse salivation, tachypnoea, cutaneous vasodilatation and frequently defaecation and vomiting. It is considered that the increased respiration is a major cause of the hypothermia. 4 Prior administration of phentolamine antagonized noradrenaline-induced hypothermia but did not affect hypothermia produced by TRH or calcium ions. Pretreatment with alpha-methyltyrosine did not affect the hypothermia induced by TRH, calcium ions or noradrenaline. 5 The calcium antagonists verapamil and xylocaine did not antagonize hypothermia induced by an injection of calcium ions. 6 The constituent amino acids of TRH did not produce hypothermia either individually or collectively. Thyroxine sodium produced a rise in temperature that was slow in onset, consistent with its known metabolic effects. TSH produced a small hypothermia unrelated to dose.

Urethral obstruction induced in adult male cats caused clinical signs identical with those observed in naturally occurring disease. Central nervous system depression, anorexia, dehydration, vomiting, muscle weakness, and hypothermia occurred. Weight loss (due to water loss and catabolism), metabolic acidosis, mild hyponatremia, hyperkalemia, hypermagnesemia, hypocalcemia, hyperphosphatemia, hyperglycemia, azotemia, and hyperproteinemia were also observed. Serum amylase, alkaline phosphatase, and alanine aminotransferase activities were normal. Ten of 13 cats (group 1), with 72 hours' induced obstruction but not treated with parenteral fluids, died either before the obstruction was relieved or within 8 days afterward. Eight cats (group 2) with induced obstruction for 49 to 98 hours developed severe clinical and biochemical alterations. Treatment with a multiple-electrolyte solution, in addition to relief of urethral obstruction, resulted in favorable clinical and biochemical responses. These cats survived and were clinically healthy at 9 to 10 days after relief of obstruction. It was concluded that use of a multiple-electrolyte solution to correct acidosis, restore circulatory volume, and enhance renal excretion of potassium was effective supportive therapy after urethral obstruction was removed.

A 13 1/2-month-old boy with severe microcephaly was found to have nearly total absence of the telencephalon. The patient had marmorated skin, hypoplastic penis and undescended testes. Spastic tetraparesis was present. Moro, grasp and sucking reflexes were easily elicited. He could not sit or stand, but was able to raise and support his head. He had occasional convulsions and a tendency to hypothermia and vomiting. The EEG showed symmetrical low-voltage theta-delta activity. His psychomotor development was severely retarded. Bone age was normal. Head circumference was 28cm at six months and did not increase after this age. At autopsy the small cranial vault and meninges were found to be intact. Brain weight was 105g. The supratentorial part of the brain was extremely small, consisting of an irregularly lobulated mass about 3cm in diameter and without any median fissure or ventricular cavity. The telencephalon was severely involved and partly replaced by gliomesenchymal scar tissue, while the diencephalic structures, including the eyes and the optic nerves and chiasm, were comparatively well-developed. The cerebellum and brain stem were essentially intact.

Hyperthermia has recently been recognized as a manifestation of hypoglycemia. We describe two episodes of hypoglycemia associated with nausea, vomiting, chills, and impaired consciousness which were followed by marked hyperthermia. We suggest that the hyperthermia may result from excessive reaction to preceding hypothermia caused by the hypoglycemia. We would like to alert the clinician to the possibility of a previous, severe hypoglycemic episode in any diabetic patient with hyperthermia and coma.

Butaclamol hydrochloride (AY-23,028) is a member of a new chemical class for which antipsychotic activity in humans has recently been demonstrated. The compound antagonized amphetamine-induced stereotyped behavior in rats, amphetamine toxicity in aggregated mice and apomorphine-induced emesis in dogs. It depressed both discriminated avoidance and continuous lever-pressing behavior in rats and inhibited ambulation and rearing in the open field. At higher doses, AY-23,028 induced catalepsy. Adrenergic blocking activity, measured by the antagonism of epinephrine-induced mortality, was weak. These pharmacological actions are characteristic of neuroleptic drugs. In the dose range where the aforementioned effects were observed AY-23,028 did not antagonize either the tetrabenazine-induced ptosis or the tremorine syndrome and did not cause either hypothermia or ataxia. The potency and onset of action of AY-23,028 were comparable to those of fluphenazine but AY-23,028 was of longer duration. The results are discussed in relation to current concepts of neuroleptic mechanisms.

Penfluridol, at relatively low doses, blocks apomorphine-elicited emesis in dogs and apomorphine-elicited floor pecking in pigeons for over a month. In mice tested for apomorphine-elicited hypothermia, and in rats tested for apomorphine-elicited chewing behavior, however, the anti-apomorphine activity of penfluridol does not persist for longer than 2-3 days even when high doses of penfluridol are given. In rabbits tested for apomorphine-induced hyperthermia and gnawing, on the other hand, penfluridol blocks apomorphine for about a week. Thus, of the 5 species tested, only in rabbits does the duration of penfluridol's anti-apomorphine action approximate the 1-week duration reported from human therapeutic trials. In mice given high-dose penfluridol apomorphine consistently elevates body temperatures, rather than exerts its usual hypothermic response. Conversely, in rabbits given penfluridol apomorphine tends slightly to decrease body temperatures, rather than exert its usual hyperthermic response.

Infants with athyrotic hypothyroidism usually manifest signs and symptoms of hypothyroidism prior to or during the period in the newborn nursery. These features are variable and include: prolonged gestation with large size at birth, large posterior fontanel, respiratory distress, hypothermia, peripheral cyanosis, hypoactivity, poor feeding, lag in onset of stooling, abdominal distension with vomiting, protracted icterus, and/or edema. Retrospective assessment of newborn nursery records of three infants from the Collaborative Perinatal Project who were subsequently found to have congenital hypothyroidism disclosed that they had six, eight, and nine, respectively, of these features while in the newborn nursery. Evaluation of newborn records on 12 other infants, often less complete, who were later found to have congenital hypothyroidism disclosed that each infant had from one to seven of these signs and symptoms, with an average of 3.2 per infant. Thus the most important period for clinical consideration of athyrotic hypothyroidism is in the newborn nursery to initiate early thyroid replacement therapy in affected infants.
