Nicotine poisoning is a rarely reported toxicosis. The clinical signs and symptoms are complex and are mostly of central nervous system derangement. In addition, animals may have hypersalivation, vomiting, diarrhea, tachycardia, tachypnea, hypertension and hyperthermia. Some animals are presented in total collapse with slow and shallow respirations, hypotension, dilated pupils, and a weak, rapid and irregular pulse. Treatment is directed toward removing the unabsorbed poison and diluting, and counteracting or controlling the animal's signs. This report emphasises the comparative ease with which a dog would readily ingest chewing tobacco, which is sweet in taste, and come down with nicotine poisoning, as compared to cigarette tobacco which is nonpalatable and therefore less of a threat. The report further discusses clinical nicotine toxicosis, its incidence, clinical manifestations, diagnosis, prognosis and treatment.

Nineteen children with clinical diagnoses of renal tubular acidosis were followed for periods ranging from 3 months to 20 years. Twelve patients had Type 1 renal tubular acidosis, five had Type 2, and two had Type 4. No sex predilection was found for any one of the types. Most patients had been diagnosed before 18 months of age, with failure to thrive the most common presentation. Tachypnea, polydipsia, polyuria, and vomiting were frequent symptoms. Some of these children had associated renal hypoplasia, vesicoureteral reflux, unilateral renal agenesis, glomerulocystic disease, adult polycystic kidney disease, and cyanotic congenital heart disease. Urinary anion gap may be useful for differential diagnosis of altered distal urinary acidification from other hyperchloremic metabolic acidosis. Furosemide test may need further investigation. Inability to raise urine to blood pCO2 gradient is helpful for diagnosis of Type 1 renal tubular acidosis. Hypokalemia, hypocalcemia, hypophosphatemia, decreased tubular reabsorption of phosphate, and hypercalciuria occurred in some patients. Complications included rickets in two, nephrocalcinosis in one, and episodic hematuria in one. There was relative bicarbonate wasting in children with Type 1 renal tubular acidosis, with a mean therapeutic bicarbonate requirement of 4.4 +/- 2.6 meq/kg/day. The mean bicarbonate dose for patients with Type 2 renal tubular acidosis was 8.3 +/- 2.6 meq/kg/day. Most children had good response to treatment with complete catch-up linear growth in 13, improved growth in 4, and continuing poor growth in 2. Two patients died during follow-up. Two other patients maintained normal growth without medication.

Intoxication with metaproterenol, a mainly beta-2 selective agonist, was diagnosed in a dog with tachycardia, tachypnea, weakness, vomiting, and a history of exposure to the drug. Electrocardiography and echocardiography disclosed sinus tachycardia with episodes of ventricular tachycardia and exuberant systolic ventricular function, respectively. Administration of the beta blocking drugs propranolol and atenolol led to resolution of the clinical signs. Excessive sympathetic stimulation caused by metaproterenol is an unusual intoxication in dogs.

A 19-year old woman who developed rapid nausea, vomiting, tachypnea, and alkalosis within 90 min of taking 3.25 g quinine S04 to induce abortion, was found to have an elevated anion gap and other electrolyte abnormalities. She was normovolemic, and had benign findings on drug screen except for quinine. Her abnormal laboratory values were high serum anion gap of 20 (normal 8-14), high urine anion gap of 171, low HC03- of 29 mEq/L, high Pa)@ of 130 mm Hg, alkalotic pH of 7.5, and hypokalemia of 2.6 mEq/L. Her hypokalemia was judged due to diuresis and vomiting. She was successfully treated with intravenous fluids and supportive care and was discharged on the third day. Quinine intoxication can also cause cinchonism, which is marked by tinnitus, vertigo, blurred vision and scotomata, and possible optic atrophy or death. The toxic dose is 2 g, and the lethal dose 8 g.

Vomiting as a dominant symptom in a patient with acute asthma is reported. The traditionally recognized triad of cough, tachypnea and wheezing were absent or trivial whenever this patient presented with persistent vomiting. A careful history, laboratory evaluation and a course of bronchodilators eventually ascertained that the episodes of vomiting were due to attacks of acute asthma. It is suggested that acute asthma be included in the differential diagnosis of recurrent and/or severe vomiting in children.

Meconium peritonitis is an aseptic peritonitis that follows a perforation of the intestines in fetal life. It is a serious complication of intestinal perforation. This article reports a female newborn who was born with gestational age of 40 weeks and birth body weight of 3400 gm. She was admitted at age of 6 days, owing to persistent vomiting, abdominal distention, tachypnea and acrocyanosis since birth. The plain abdomen showed intra-abdominal calcification and intestinal distention. Under the impression of meconium peritonitis, she was treated aggressively with exploratory laparotomy, TPN and antibiotics. During operation, dense fibrous adhesions and agglutination of the intestine were found. But no intestinal perforation was noted. Culture of ascites isolated Enterobacter aerogenes. The patient's condition was gradually recovered and she was discharged at age of 32 days. According to the previous literature, meconium peritonitis is a relative rare disease with poor prognosis. So we would like to report this case.

The effects of eight neuroleptic drugs injected into the cerebral ventricles on behavior, autonomic and motor activity of unanesthetized cats have been studied. Chlorpromazine, trifluorpromazine, droperidol, haloperidol, domperidone and spiperone induced emotional behavior (restlessness, miaowing, rage, attack, defense, fighting with paws, biting), autonomic (mydriasis, tachypnoea, dyspnoea, panting, salivation, defecation, urination, licking, vomiting) and motor (ataxia, muscular weakness, adynamia) phenomena. The main and the most consistent effect was the motor impairment, while the aggression was inconsistent and of moderate intensity. Of the neuroleptic drugs injected, only spiperone, domperidone and trifluorpromazine produced a dose-dependent motor impairment. The autonomic effects were also inconsistent and of low intensity. Metoclopramide induced inconsistent autonomic and motor effects, while sulpiride was devoid of any visible behavioral, autonomic and motor activity. It appears, therefore, that the motor impairment as well as the aggression caused by the neuroleptic drugs is perhaps related to central D-1 rather than to central D-2 dopamine receptors, but an effect on central norepinephrine and on central serotonin receptors cannot be excluded.

Four hundred and fifty-three adults in 25 British hospitals entered a prospective study of community-acquired pneumonia. A microbiological diagnosis was established in 67 per cent; Streptococcus pneumoniae (34 per cent). Mycoplasma pneumoniae (18 per cent) and Influenza A virus (7 per cent) were the commonest microorganisms. Our observations support the view that most of those in the microbiologically negative group (33 per cent) had S. pneumoniae infection. In addition to cultures of blood and sputum the most useful initial tests were for sputum pneumococcal antigen and serum mycoplasma specific IgM. Twenty-six patients (5.7 per cent) died, seven within 48 h of admission. Multivariate analyses showed age, absence of chest pain, absence of vomiting, previous treatment with digoxin, tachypnoea, diastolic hypotension, confusion, leucopenia, leucocytosis, and raised blood urea levels were significantly correlated with death. Patients had a 21-fold increased risk of death if they had two of the following: admission respiratory rate greater than or equal to 30/min, admission diastolic BP less than or equal to 60 mmHg, urea greater than 7 mmol/l during admission. Mortality was not related to aetiology except that all three patients with combined Influenza A virus and Staphylococcus aureus infection died. Nine patients had legionella pneumonia; none died. No patients who died from pneumococcal pneumonia, mycoplasma pneumonia or staphylococcal pneumonia had received an appropriate antibiotic before admission. Such deaths are possibly preventable. Assisted ventilation was used in 22 patients of whom 14 survived. Hospital stay in survivors averaged 10.8 days; after six weeks 79 per cent were fit for normal activities, and 55 per cent showed resolution of radiographic signs of pneumonia. We recommend that antibiotics should be given as early as possible and chosen always to cover S. pneumoniae, and in addition M. pneumoniae during outbreaks, and S. aureus during influenza epidemics.

The effect on behavior of eight anticholinergic agents: atropine, scopolamine, trihexyphenidyl, biperiden, homatropine, eucatropine, hexocyclium and propantheline, injected into the cerebral ventricle (ICV) of the cat was investigated and compared. The anticholinergic agents evoked: (1) psychomotor stimulation such as miaowing, loud calling, restlessness, impelling locomotion, jumping, vacant staring, apprehension and loss of interest of the surroundings; (2) aggression, hissing, threat, attack, defense, fighting with paws and flight; (3) autonomic responses including mydriasis, tachypnea, dyspnea, licking, vomiting, salivation, micturition and defection; and (4) motor phenomena comprising scratching, ataxia, rigidity, tremor, weakness with adynamia or myoclonic jerks. Convulsions appeared only after ICV injections of atropine and homatropine. The most characteristic behavioral effect of anticholinergic agents was psychomotor stimulation accompanied by mild aggressive responses. The only exception was propantheline which caused a muscular weakness and adynamia. Atropine and scopolamine alone induced a dose-dependent impelling locomotion as well as fighting behavior. Carbachol and eserine injected intracerebroventricularly reversed the locomotion autonomic and motor phenomena produced by anticholinergic agents administered similarly. It is suggested that anticholinergic agents acting as partial agonists, can produce their behavioral effects through central cholinoceptive sites.

Bacterial infections are frequent events in premature and newborn infants. The reason is a defective specific and nonspecific defence of bacterial organisms. Some immunoglobulins like IgM and IgA including secretory IgA are absent. Premature infants also show a decreased level of IgG. Cellular immunity is anatomically intact but functionally defective. A number of complement factors are lacking, the activation of the alternative pathway is impaired. Newborn infants with perinatal problems like asphyxia or difficult delivery, show defects of leucocyte function like decreased deformability, defective chemotaxis and defective killing of ingested bacteria. Certain diseases, like hypoxia and malformations of immature organ functions in this age group (decreased acid production in the stomach), facilitate bacterial colonization of surface epithelia and the invasion of tissues. Consequences of these pathogenetic mechanisms are an unimpaired propagation of bacterial organisms into the blood and meninges without localization of the infecting organisms at the entry site. Bacterial meningitis is not considered a separate disease entity but a complication of bacteremia and sepsis. Clinical symptoms are nonspecific at the onset of the infection. Fever is frequently absent; decreased appetite, vomiting, a bloated abdomen, diarrhea, tachycardia, tachypnea are early signs of a bacterial infection, a grey mottled appearance, cyanosis, jaundice, petechiae, apneic spells, seizure activity and a metabolic acidosis are symptoms of advanced infection. Successful treatment at this stage is often not possible. Every sign of a decreased well being of a newborn of premature infant warrants laboratory and bacteriologic work up for septicemia.(ABSTRACT TRUNCATED AT 250 WORDS)
