The incidence of toxicity associated with the use of valproic acid (VPA) is considered remarkably low compared to other antiepileptic drugs. This study reports the toxicity of VPA administered as a single drug to 88 children in relation to the daily dose and drug plasma level. The frequency of side effects observed clinically was 42.0%, but it increased to 80.7% when a questionnaire was introduced. In spite of the limitations of this method, the results show the need to perform systematic surveillance for side effects of all antiepileptic drugs, similar to those made to assess their clinical effectiveness. Anorexia, vomiting, and sleep alterations were the most common side effects detected in the clinical record; patients who showed anorexia, hyperactivity, lassitude, sleep disturbances, and sadness had received daily doses significantly higher than patients not showing side effects. Similarly, the children who needed to reduce or discontinue the treatment were receiving the highest doses. No relations, however, could be established between the incidence of side effects and plasma levels of VPA except for lassitude and drowsiness. Severe or fatal toxicity was not detected.

Analyses of 23 fatal instances of hepatic injury in patients taking valproic acid reveals that all but three were less than 20 years old, and all but four had been taking the drugs for more than 1 month. Convulsions, facial edema, lassitude, and vomiting were prominent clinical features. Hypoglycemia was recorded in six patients. Rash and eosinophilia were not seen. Values for transaminases were modestly elevated in most patients. Most levels of SGOT were below 500 IU, and SGPT levels were below 200 IU. Livers showed microvesicular steatosis in most patients, usually accompanies by necrosis. Four patients had cirrhosis. Overt valproic acid-induced hepatic injury appears to be rare and hence, by definition, idiosyncratic. That it may be an idiosyncratic exaggeration of a much more frequent phenomenon is suggested by the higher incidence of seemingly trivial injury. The idiosyncrasy appears to be metabolic rather than immunologic, and the available information leads to the plausible hypothesis that a metabolite is responsible for the microvesicular steatosis seen in most fatal cases. The steatosis resembles that of Reye's syndrome and Jamaican vomiting sickness, and there is reason to believe that the metabolite responsible for the steatosis resembles the agent responsible for Jamaican vomiting sickness. A different metabolite is presumably responsible for the necrosis seen in many of the cases.

In outlining the pathology of various electrolyte metabolism abnormalities in cancer patients we considered the main clinical points between pathologies and emergency treatment. In regard to sodium (Na+) metabolism, one pathologic state that requires our attention is hypernatremia. Hypernatremia is accompanied with dehydration and is due to water loss, vomiting, diarrhea and renal insufficiency. One of the major causes of this condition is lack of the antidiuretic hormone due to intracranial metastasis of the tumor. When hypernatremia becomes severe, it is accompanied with circulatory failure, muscular asthenia, disorientation, convulsions, coma and other cerebral symptoms. Treatment consists of replenishing the water content by infusion of electrolyte solutions which should be carefully conducted after complete diagnose of the severity of the patient's pathological condition. Hyponatremia, like sick cell syndrome, is observed relatively frequently in cancer patients. When the serum Na level falls markedly, it induces cerebral edema and causes disorders of consciousness. The major treatment consists of providing both water and sodium supplements. Hyperkalemia is observed at the time of renal insufficiency, tissue lesions, vomiting, and diarrhea. When serum potassium level rises, it causes bradycardia, ventricular fibrillation, or cardiac arrest. It is important to diagnostically apprehend the severity of this condition using EKG and determining the serum K1+ level. For emergency treatment injection of calcium gluconate is very effective. Hypokalemia is often manifested by the loss of intestinal fluids due to diarrhea or during administration of diuretic agents. Clinical symptoms include neural paralysis but emergencies occur relatively infrequently. K C1 injections are used in treating this condition. Hypercalcemia is manifested in cancer patients during hyperparathyroidism. Its clinical symptoms include lassitude, tachycardia, nausea, vomiting, and renal dys-function, leading to neural symptoms in severe cases. The main treatment consists of injection of physiological saline solution and administration of calcitonin, mithramycin. Hypocalemia is manifested during renal insufficiency, lack of vitamin D, and hypothyroidism. In classic cases it causes tetanic spasms. Injection of calcium is an effective treatment but since during tetanic spasms alcalosis may easily occur, treatment should only be provided after obtaining a complete understanding of the patient's condition. The pathological conditions described above can not be said to specific to cancer but it should be kept in mind that one of their main causative factors is the involvement of mechanism which produces ectopic hormones from cancerous tissues.

Phase II study of cis-diaminedichloroplatinum(II) (CIS-DDP) administered intravenously was performed in 77 patients with urologic malignancies for the evaluation of clinical responses and adverse effects. The eligibility of the patients and evaluation of response were carried out according to the general criteria proposed by Drs. Koyama and Saito. Out of 85 patients, entered in this phase II study, 77 patients were considered evaluable. Complete responses were seen in 4 patients, 3 testicular tumor and 1 bladder cancer. Partial response were obtained in 24 patients; 10 bladder cancer, 8 testicular tumor, 5 prostatic cancer, and 1 renal cell carcinoma. Overall response rates were 73.3% in testicular tumor, 50.0% in bladder tumor, 20.8% in prostatic cancer, and 7.7% in renal cell carcinoma. Incidences of toxicities were noted in the gastrointestinal tract. Nausea, vomiting, anorexia, abdominal pain, and diarrhea were observed in 78.5% of the patients treated with CIS-DDP. Myelosuppression, lassitude, renal and hearing dysfunction were other prominent adverse effects.

T-2 toxin was given to cats every other day per os to evaluate the suitability of this species as a model for the human disease, alimentary toxic aleukia. The chronic lethal intoxication resulting was characterized by pancytopenia, hemorrhagic diatheses, bone marrow aplasia, diminished hemostasis, severe lymphatic tissue alterations, and histopathologic changes in proliferative tissue. Clinical signs included vomiting, bloody feces, weakness, lassitude, ataxia, dyspnea, dehydration, loss of weight, and pre-terminal anorexia. The clinical course, hematologic picture, and the gross and microscopic tissue changes seen in the experimentally produced disease in cats were similar to alimentary toxic aleukia, a frequently fatal mycotoxin induced disease of man.

The knowledge and use of newer, more sensitive, and reliable pregnancy tests which are easily accessible and of moderate cost are the 1st steps in the early diagnosis and management of pregnancy, especially in adolescent girls. Accurate diagnosis of pregnancy soon after conception offers the option of abortion by simple, effective, and inexpensive procedures or early initiation of prenatal maternity care. Discussion focuses on the symptoms of pregnancy and the historical development and basis of pregnancy tests as well as the specific types of pregnancy tests. The most familiar sign of pregnancy is the missed period. Other symptoms that provide presumptive evidence of pregnancy include fatigue and lassitude, increased body temperature, and breast fullness or pain. Feelings of nausea, vomiting, and weight gain may appear after 2 weeks. The diagnosis of pregnancy by the detection of the human chorionic gonadotropin was initially described 53 years ago by Selmar Aschheim and Bernhardt Zondek. Improvements in the techniques for the measurement of human chorionic gonadotropin (hCG) have been directly related to the progress in the purification and isolation of hCG and elucidation of the amino acid sequence of the hormone-nonspecific alpha subunit and hormone-specific beta subunit of hCG. The history, physical examination, and pregnancy tests will generally provide sufficient information for a definite diagnosis of pregnancy. The presence of hCG in the urine or blood is the most accurate of all the indications of pregnancy. During the last century, 4 different techniques for the determination of hCG in blood and/or urine have been developed. These include the following and are reviewed in detail: 1) bioassays in intact laboratory animals; 2) immunologic tube or slide methods with heme- or latex-agglutination inhibition, as well as the more recently developed competitive protein binding method such as 3) radioimmunoassay (RIA) for the use of radioisotope labeled hormone and the specific antiserum against hCG; and 4) radioreceptorassay by the use of radioisotope-labeled hormone with biological activity and the specific receptors as the binding proteins.

A field case involving seven recently inseminated Yorkshire sows injected with penicillin is described. About four hours after injection, the pigs showed shivering, incoordination, vomiting, extreme lassitude, pyrexia (41 degrees C) and to;al inappetence. In each case, a thick, white mucous discharge appeared from the vulva one to three days after injection, with distinct embryos in some cases. Further experiments on pregnant and fattening pigs indicated that untoward reactions to penicillin could arise in swine--in particular, embryonic death.

1. The safety in everyday clinical usage of three 4-quinolone antibiotics, (ciprofloxacin, norfloxacin and ofloxacin), was compared with similar data for azithromycin and cefixime, each agent being examined by Prescription-Event Monitoring (PEM) during the early post-marketing period. 2. In PEM the exposure data are derived from general practitioner prescriptions confidentially provided by the Prescription Pricing Authority. Outcome data are provided by questionnaires (green forms) on which the prescribing medical practitioner records event data. When necessary, further information is obtained from a number of sources which include follow-up of all pregnancies and the patients' life-time medical record. 3. The main outcome measures were demographic information, including the patient's date of birth and sex; the indication for prescribing the drug being monitored; the reason for stopping treatment; the start and stop dates of treatment and the events recorded during and after treatment. 4. The final cohort for each of the five antibiotics exceeded 11000 patients. The only event significantly related to the use of all five antibiotics was nausea/vomiting. This was also the most frequent adverse event causing treatment to be discontinued with norfloxacin, ofloxacin and azithromycin (relevant information was not requested in the studies of ciprofloxacin and cefixime). Vaginal candidiasis was significantly more frequently associated with the use of the three 4-quinolones than with azithromycin and cefixime but it was frequently delayed until the week or two after the cessation of therapy. Within each event, as recorded in these studies, the highest event rates (the number of events per 1000 patients) in the week following the start of therapy were: 9.2 for diarrhoea with cefixime; 4.9 for nausea/vomiting with ofloxacin; 2.4 for rash with azithromycin; 2.2 for abdominal pain with norfloxacin; 1.5 for headache/migraine with ofloxacin; 1.4 for malaise/lassitude with ofloxacin; 1.2 for dizziness with norfloxacin. Uncommon events (reported in less than 1:1000 patients) included rare cases of allergic phenomena, convulsions and pseudomembranous colitis. There were no reports of tendinitis, tenosynovitis or tendon rupture in children but tendon disorders were reported in the two months following the start of treatment in 20 adults. A total of 307 pregnancies were reported. Thirty-eight of the 55 women who received these drugs during the first trimester of pregnancy gave birth to healthy babies. No congenital abnormalities were reported. Apart from one case of unconfirmed pseudomembranous colitis, none of the other 2468 deaths that occurred in these studies was attributed to the antibiotics. 5. These five antibiotics are acceptably safe antimicrobial agents when used in general medical practice. PEM is an effective method for monitoring the safety of recently introduced antimicrobial agents.

This paper examines associations between symptoms, judgement of severity and treatments given for episodes of childhood diarrhea. Using data from ten large sample surveys conducted in six research sites in Asia and Africa, the paper addresses three main questions. One, to what extent are judgments of severity of diarrhea among young children a function of the symptoms observed during an episode of diarrhea? Two, what is the relative importance of symptoms observed vs judgments of severity in the treatments given for diarrhea? And three, what do the results imply for programs promoting the use of ORT for diarrhea? The study found that mothers, perception of severity of illness is linked most closely to three symptoms: vomiting, fever and lassitude. These symptoms are associated with (a) treating the child at all and (b) taking the child to a health facility. These conclusions take on particular significance since they are based on a comparison of ten data sets from six sites differing widely in population density, ecology, access to medical services, educational level and financial resources.

Acute mountain sickness and high altitude cerebral edema are specific pathologies of high altitude exposure. The usual symptoms of acute mountain sickness are headache, nausea, vomiting, insomnia, lassitude, dizziness and ataxia. High altitude cerebral oedema is a severe state of acute mountain sickness with, in addition, alteration of mental status and consciousness. The pathophysiology of these 2 diseases are essentially due to an increase of intracranial pressure directly dependent of an increase of cerebral volume. Molecular and cellular mechanisms underlying acute mountain sickness and high altitude cerebral oedema are still poorly understood. The regulation of cerebral blood flow by nitric oxide seems to play a major role.
