The prevalence, presentation, and outcome of bacteremia due to Shigella and other gram-negative bacteria were determined by review of records of 2,018 inpatients with shigellosis who had their blood cultured in a Bangladeshi hospital in 1976-1983. Shigella bacteremia occurred in 82 (4.1%) patients; other bacteremia occurred in 102 (5.1%) patients. Patients with shigella sepsis more frequently (P less than .02) manifested severe dehydration, abdominal tenderness or ileus, agitation or lethargy, and leukocytosis than did nonbacteremic controls; they developed more frequently (P less than .05) renal failure (26%), leukemoid reaction (22%), thrombocytopenia (20%), and hemolytic-uremic syndrome (6%). The prevalence of all bacteremia was highest in the first year of life. Protein-energy malnutrition was a strong risk factor for shigella sepsis (P less than .01). The fatality rate in shigella bacteremia (21%) was higher (P less than .005) than in nonbacteremic shigellosis (10%) but lower (P less than .001) than in other bacteremia (51%). At highest risk of death from shigella bacteremia (P less than .01) were patients less than one year old, non-breast-fed, malnourished, and afebrile.

Six marrow transplant recipients receiving acyclovir at various dosages for herpesvirus infections developed neurologic symptoms during treatment. Three were receiving concomitant human alpha interferon, and all six had received previous intrathecal methotrexate. Symptoms developed a median of 8 days (range, 2 to 18 days) after initiation of therapy and consisted of lethargy or agitation in five patients, tremor in five, and disorientation or transient hemiparesthesias in one patient each. The only consistent laboratory finding was an abnormal electroencephalogram. Five patients had an increased myelin basic protein level in cerebrospinal fluid. Improvement or resolution of symptoms occurred a median of 13 days (range, 4 to 15 days) after cessation of acyclovir therapy. Acyclovir used at a wide range of dosages may be associated with reversible neurologic symptoms in patients after marrow transplantation. The contribution of previous prophylaxis for central nervous system leukemia, herpesvirus infections, marrow transplantation, or the concomitant use of interferon is unknown.

In four children with iatrogenic morphine sulfate tolerance and dependence, narcotic withdrawal was successfully accomplished using propoxyphene napsylate. The patients showed signs and symptoms typical of narcotic withdrawal, which resolved with morphine administration and increased during attempts to lower the daily morphine dose. Propoxyphene napsylate at total daily doses of 25 to 65 mg/kg, administered at four-hour intervals, allowed rapid reduction of the morphine dosage, with few withdrawal signs and symptoms, and lessened respiratory depression. This treatment enabled patients to be rapidly weaned from the respirator. One child experienced increasing lethargy and respiratory depression and responded to naloxone hydrochloride and a decrease in the dose of propoxyphene; another had transient agitation, which may have been related to high levels of propoxyphene. Our treatment used alternating doses of propoxyphene and morphine, which allowed the child to be morphine free after four days and narcotic free after nine days.

In 1,000 cases of phencyclidine (PCP) intoxication evaluated at the time of first examination in an emergency department, the incidence of "typical" findings was found to be lower than has been reported previously. Nystagmus and hypertension occurred in only 57% of our cases; some patients had only one of these findings and many had neither. The incidence of violence was 35%; bizarre behavior, 29%; and agitation, 34%. Changes in sensorium consisted of coma, lethargy/stupor, and acute brain syndrome; however, 46% of patients were alert and oriented. Motor signs included grand mal seizures, generalized rigidity, localized dystonias, catalepsy, and athetosis. Profuse diaphoresis, hypersalivation, bronchospasm, and urinary retention occurred in less than 5%. A small percentage had severe disturbances in vital signs, including three cases (0.3%) of cardiac arrest and 28 cases (2.8%) of apnea. Hypoglycemia and elevated serum CPK, uric acid, and SGOT/SPGT were common. Urine PCP levels did not correlate with the severity of the clinical findings.

We describe four major and five minor clinical patterns of acute phencyclidine (PCP) intoxication and give the incidence of findings in each pattern. Major patterns were acute brain syndrome (248 cases; 24.8%), toxic psychosis (166 cases; 16.6%), catatonic syndrome (117 cases; 11.7%), and coma (106 cases; 10.6%). Minor patterns included lethargy or stupor (38 cases; 3.8%), and combinations of bizarre behavior, violence, agitation, and euphoria in patients who were alert and oriented (325 cases; 32.5%). Patients with major patterns of PCP toxicity usually required hospitalization and accounted for most complications. In general, patients with minor patterns had mild intoxication and did not require hospitalization except for the treatment of injuries or autonomic effects of PCP. Various types of injuries occurred in 16%, and aspiration pneumonia occurred in 1.0% of all cases. There were 22 cases of rhabdomyolysis (2.2%), with three patients requiring dialysis for renal failure. One patient who had been comatose from PCP died suddenly. A fresh pulmonary embolism was found at autopsy.

Ornithine transcarbamylase deficiency (OTCD) is caused by an alteration of urea synthesis, linked with partial modification of the X-chromosome, whose clinical manifestations are: lethargy, nausea, vomiting and cerebral edema. While in newborn males OTCD presents with hyperammoniemia leading to cerebral palsy with profound neurological impairment and eventually death, in women who are healthy carriers, it is possible to detect the disorder only through specific tests, since heterozygote women are rarely symptomatic. We describe the case of a young woman admitted to the hospital after an episode of mental confusion with vomiting and psychomotor restlessness, which had previously occurred several times during the premenstruum and lasted a few hours. A 2 day history of stupor made admission mandatory. Tests carried out during the hospital stay showed marked hyperammoniemia and unconjugated hyperbilirubinemia, marked cerebral edema documented by a CT scan. Liver biopsy and CSF test were normal. Screening of plasma and urinary aminoacids, level of orotic acid in the urine and OTC activity in the liver, confirmed the diagnosis of OTCD. The possibility of early diagnosis and therapy of a disease which otherwise leads to death, emphasizes the importance of precise evaluation of a possible organic cause of anorexia and behaviour disorders in young women.

Adolescent depression occurs within various developmental, social, and biologic contexts, and is manifested by traditional depressive symptoms such as fatigue, loss of interest in daily activities, weight changes, sleep disturbances, sad moods, difficulty with concentration, behavioral agitation or lethargy, feelings of worthlessness, and recurrent thoughts of death. Depressed adolescents may combine these symptoms with certain additional behaviors such as academic deterioration, substance abuse, sexual activity, somatic complaints, eating disorders, conduct disorders, and other risk-taking behaviors. School nurses can play a central role in the prevention, assessment, referral, and follow-up care of this significant adolescent health problem.

Neurological abnormalities including agitation, confusion, disorientation, lethargy, and obtundation are early characteristic findings in patients with sepsis. The etiology of the changes in mental status that occur during severe infection is unknown. We investigated the effects of sepsis on intermediary metabolism and bioenergetics in the brain during normoxia and moderate hypoxia (8% inspired O2 concentration) in rats 36-42 hr following cecal ligation and perforation. The rats were anesthetized with halothane, and brains frozen using the funnel-freezing technique. Perchloric acid extracts of brains were analyzed with fluorometric enzymatic methods and 31P nuclear magnetic resonance spectroscopy. There was no impairment in bioenergetics or intermediary metabolism in septic brain, and sepsis did not compromise the ability of the brain to maintain high-energy phosphates during hypoxia. Hypoxia did cause the brain lactate-to-pyruvate ratio to increase equivalently in both septic and control rats from approximately 9:1 to 20:1 (P < 0.001). We conclude that the neurologic changes which are characteristic of sepsis are unlikely to be due to alterations in cellular energy stores or intermediately metabolism. In addition, there is no evidence that sepsis results in brain cellular hypoxia.

A study was undertaken to provide further information on the ruminal, cardiorespiratory and hypothalamo-pituitary-adrenocortical (HPAC) physiological sequelae of hypocalcaemia in dairy calves. The functional picture observed in standing calves experiencing Na2EDTA-induced progressive hypocalcaemia showed a biphasic pattern. During the first phase (Ca2+ varying between 1.20 +/- 0.09 and 0.64 +/- 0.15 mmol/L, mean +/- SD), the animals became dull and lethargic, shifting their weight from one hind limb to the other, with cool extremities and hypersalivation. Their ventilation was slightly increased but their heart rate, thoracoabdominal pressure, pulmonary mechanics, haemoglobin and temperature remained constant. Conversely, their systemic arterial pressure (SAP) and the amplitude of their ruminal contractions (RCA) were severely decreased. During the second phase (Ca2+ < 0.64 +/- 0.15 mmol/L), there was restlessness, tachycardia, hypertension, polycythaemia and, finally, inability to stay upright. It is suggested that the diminished Ca2+ availability caused smooth-muscle and myocardial dysfunctions which could explain the RCA and SAP changes recorded during the first phase, whereas neural and/or humoral sympathetic discharge probably accounted for the reversal in SAP and heart rate when Ca2+ was decreased further. Serum cortisol increased regularly and remained significantly correlated with Ca2+ in each animal. Moreover, regression of delta cortisol/delta Ca2+ on delta Ca2+/delta Na2EDTA was significant (p < or = 0.001). It was concluded that mild asymptomatic hypocalcaemia severely impairs ruminal function, which will progressively worsen the Ca2+ deficit; that the inability to maintain posture in hypocalcaemia is not due to hypotension; and that the higher the HPAC response to hypocalcaemia, the higher the resistance to its effects. An asymptomatic periparturient cow with barely detectable ruminal activity may merit preventive calcium borogluconate therapy. Also, the physiological role of hypotension in explaining the clinical picture may be less important than other processes, such as neuromuscular failure. Finally, the present results imply a possible HPAC exhaustion in cows with periparturient paretic hypocalcaemia.

Thirty adults with Prader-Willi syndrome (PWS) were compared with 30 adults with non-specific learning disability matched for age, sex and severity of mental retardation. Maladaptive behaviour was assessed with the Aberrant Behavior Checklist (ABC), a 58-item structured interview which rates behaviours from 0 (not a problem) to 3 (severe problem) and which yields five factors (I) irritability, agitation; (II) lethargy, withdrawal; (III) stereotypic behavior; (IV) hyperactivity, non-compliance; and (V) inappropriate speech). The PWS sample had significantly higher factor I (P < 0.001) and factor V (P < 0.05) scores. The PWS sample had mean scores above 1 for 17 ABC items; the contrast subjects had no mean scores above 1. The factor I scores for the PWS sample were similar to those of inpatients in hospital facilities for adults with mental retardation and mental illness or severely challenging behaviour. The results support previous work, and extend it by suggesting that temper tantrums, self-injury, impulsiveness, lability of mood, inactivity and repetitive speech are characteristic behaviours in PWS in adult life. Studies of the reasons for heterogeneity in behaviour are now needed.
