Cases of otitis media in infants under 12 weeks of age were reviewed to delineate the frequency, clinical features, and etiologic agents involved. Tympanocentesis was performed in 42 infants, 0 to 5 weeks of age, and in 17, from 6 to 11 weeks of age. The most common symptoms were irritability/lethargy (69%), fever (52%), cough (36%), vomiting (21%), diarrhea (20%), tachypnea (20%), and anorexia (18%). Associated illnesses were present in 33 (54%) of the patients, the most common being pneumonia (9), bronchiolitis (7), meningitis (6), conjunctivitis (4), and omphalitis (4). No peripartum infections or severe perinatal problems were found. Common respiratory pathogens were the predominant etiologic organisms, but coliform organisms were identified in 18% of the infants under 6 weeks of age. Cultures were sterile or grew organisms of questionable pathogenicity ("nonpathogens") in 39% of specimens. Since the signs and symptoms of otitis media in children less than 12 weeks of age are nonspecific and frequently associated with other major illnesses, the physician caring for these infants needs to be more aware of this disease and the therapeutic problems it presents.

A case of hyperchloremic acidosis in an infant with imperforate anus and rectourethral fistula, showing lethargy, tachypnea, vomiting, and dehydration, is reported. Surgical correction by abdominoperineal pull-through and division of the rectourethral fistula was performed after doing a cystocutaneostomy to eliminate the diversion of urine into the rectum.

Twenty infants and young children with hereditary fructose intolerance (HFI) were admitted to hospital. None was diagnosed at admission. Referals were for vomiting of unknown aetiology (16X), pyloric stenosis or hiatus hernia (5X), toxic condition (3X), and hepatomegaly of unknown origin (5X). Feeding difficulties (20X), vomiting (18X), and failure to thrive (16X) were leading symptoms. The most frequent clinical findings were hepatomegaly (18X), pallor (14X), haemorrhages (13X). Ascites, oliguria, tachypnoea, fever, splenomegaly and rickets were less frequent. Laboratory findings were indicative of disturbed hepatic and renal tubular function and also of disturbed intermediary metabolism (hypokaliaemia, hypophosphataemia). However, hypoglycaemia was found in only 4 out of 15 patients tested. Differential diagnosis after hospital admission centered on metabolic disorders such as glycogenoses, galactosaemia, tyrosinosis, or Wilson's disease. Hepatitis, toxic hepatosis, liver tumour, intrauterine infection and sepsis were also considered. Eleven children had first ingested fructose within the first 6 weeks of life. The diagnosis was usually established only many weeks or months after first fructose intake and appearance of symptoms. This documents how difficult the diagnosis of this disease can be both in practice and in hospital. The course was severe in 11 children and lethal in 4. In only 5 patients was the course mild. The 16 survivors are doing well under fructose-exclusion diet. Irreversible visual impairment after intraocular haemorrhage occurred once. In each case HFI could have been suspected immediately, had a detailed nutritional history been taken. Practising paediatricians should know the composition of commonly used infant formulae. They should never prescribe sugared condensed milk for intractable vomiting prior to excluding HFI. Solution for intravenous infusion containing fructose and sorbitol are life-threatening for undiagnosed HFI patients.

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.

Twenty-two patients were given progressively increasing doses of Cytembena to determine toxicity patterns and to establish a dosage which produces definite but clinically tolerable toxicity when the drug is given by intravenous injections in a 5-day intensive course. Toxicity consisted primarily of nausea, vomiting, arm pain, and transiently decreased renal function. At higher doses, an "autonomic-storm" phenomenon was observed consisting of hypertension, tachycardia, tachypnea, hyperperistalsis, frequent explosive defecation, facial flushing and paresthesias, and chest pain with accompanying ischemic EKG changes. There was no evidence of mucocutaneous, hepatic, or hematologic toxic effects. Toxicity was dose-related, first being recognized at a daily dose of 300 mg/m2 and becoming clinically intolerable at a daily dose of 475 mg/m2. No permanent damage was observed in any of the organ systems monitored. An acceptable treatment regimen for most patients is 400 mg/m2/day for 5 days. Patient discomfort can be reduced by dividing each day's dose into two intravenous injections given at an interval of at least 6 hours. Coronary artery disease and impaired renal function should be contraindications to Cytembena therapy, and caution should be employed in the patients with significant impairment of liver function. Two of 22 patients, both with far-advanced carcinoma and previous chemotherapy failures, showed a favorable objective response to Cytembena therapy. Phase II studies to assess the magnitude of the drug's antineoplastic activity seem warranted.

The case is reported of a non-diabetic young woman who attempted suicide by ingesting 2,500 mg of phenformin. The most marked clinical and laboratory findings during the first 24 hrs included nausea, vomiting, anxiety, agitation, polydipsia, polyuria, increased appetite, tachycardia, tachypnea, persistent lactic acidosis, hypoglycemia and hypokalemia. Treatment at the ICU 10 hrs after ingestion of the overdose was essentially symptomatic and included measures to correct acidosis and hypoglycemia. The patient recovered completely.

An overdose of up to 850 levothyroxine sodium tablets (0.2 mg) in a healthy 6-year-old 16.8-kg dog induced an episode of vomiting and hippus within 9 hours of ingestion. The dog was treated with activated charcoal and saline (magnesium sulfate) cathartic. Initially the serum concentration of thyroxine (T4) 4,900.9 nmol/L. On the second day, serum concentration of triiodothyronine (T3) was 5.3 nmol/L. Serum T4 concentration decreased slowly and was not determined to be normal until day 36. Serum T3 concentration was found to be normal on day 6. Serum alanine transaminase activity peaked on day 6 at 345 U/L. Significant abnormalities were not found during the following 36 days. Clinical signs of thyroid hormone toxicosis in dogs and cats include hyperactivity, lethargy, tachycardia, tachypnea, dyspnea, abnormal pupillary light reflexes, vomiting, and diarrhea. High overdoses of levothyroxine sodium in dogs should be managed by initial decontamination and administration of activated charcoal with a cathartic followed by supportive care.

Deficiency of 3-hydroxy-3-methylglutaryl-CoA lyase has been studied in 11 Saudi infants. The diagnosis was established by the measurement of enzyme activity in lymphocytes, in fibroblasts and, in seven patients, by the gas chromatography/mass spectrometer pattern of excreted organic acids in the urine. In seven infants the disease caused a devastating acidotic attack within the first day of life, while in two the crisis occurred by the third day of life. In two infants from one family the disease appeared later in infancy. The clinical presentation of an acidotic attack is lethargy, hyperpnoea, tachypnoea and seizures, either at birth (two infants), following first feeding (in five infants), or following vomiting or refusal of food in later infancy. The acidotic attacks recurred later in life following minor illness or refusal to eat. The acidosis of this enzyme deficiency progresses rapidly, leading to cardiopulmonary arrest and death within hours of onset unless treated promptly. In four surviving infants diagnosed and treated early, development is normal. Magnetic resonance and computerized tomography brain scans in these infants, however, show white matter lesions and mild atrophy.

A 8 day-old full-term newborn showed severe cardiac disturbances after intravenous injection of erythromycin. The neonate, suspected of having Chlamydia pneumonitis because of tachypnea and rhinitis, had been given 5 injections of erythromycin without clinical effect. Pallor, vomiting and bradycardia developed a few minutes after the 6th injection, and ECG showed ventricular arrhythmia, prolonged QT interval and an atrioventricular block. The infant died in intensive care unit. This case and the analysis of other published cases of cardiac disturbances following the parenteral use of erythromycin, indicate the potential arrhythmogenic risk of this drug. It is suggested that newborns treated with erythromycin should be monitored by ECG.

Margosa Oil is an extract of the seed of the Neem tree and is widely used as a traditional medicine by Indians in India, Sri Lanka, Burma, Thailand, Malaysia and Indonesia. Used mainly for external applications, it is often administered orally to neonates and infants regularly in small amounts. Margosa Oil causes toxic encephalopathy particularly in infants and young children. The usual features are vomiting, drowsiness, tachypnea and recurrent generalised seizures. Leucocytosis and metabolic acidosis are significant laboratory findings. Management is aimed primarily towards the control of convulsions although supportive management is equally important. Prognosis is usually good but fatalities and neurological deficits have been reported. We report here two infants with Margosa Oil poisoning presenting with encephalopathy.
