Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea,
vomiting
, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary
sodium
excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

Renal failure in itself generates a state of malnutrition, due to three main causes: inadequate ingestion (anorexia,
vomiting
or diet insufficiencies), the existence of catabolic factors (proteins, acidosis, PTH) and extrarenal depuration (which provokes a lack of amino acids and vitamins). Artificial nutrition constitutes a series of measures that can be adopted to act upon each of the above causes. Adequate ingestion compared to inadequate ingestion can be performed orally (especially in chronic renal failure) by parenteral administration (preferable in acute renal failure) and enteral administration (complementary in both cases). The quantity and quality of adequate nutrients is non-dependent on the method of administration; 500 ml, of water should be administered plus diuresis, plus loss from other tracts; the mineral intake of
sodium
, potassium and phosphorus should be restricted; in the case of vitamins, these should be administered, especially the B and D complexes; there should be sufficient calories to constitute a hypercaloric diet (from 30-50 kg/day), at least 50% in the form of carbohydrates (hypertonic glucose, if administered intravenously, and dextrinolmaltose or starch if administered through the digestive tract) and at least 40% in the form of lipids (preferably of vegetable origin, rich in non-saturated fatty acids); proteins are the mainstay of nutrition in renal failure; thus, with a normal renal function or in dialysis, a dose of 1 g/kg/day is recommended; in chronic renal failure, 0.5 g/kg/day; in cases of renal failure not on dialysis, 0.3 g/kg/day, supplemented by essential amino acids or cetoacids (the effectiveness of the latter is still in dispute).(ABSTRACT TRUNCATED AT 250 WORDS)

Two male siblings presented in the first 6 weeks of life with
emesis
, diarrhoea, metabolic acidosis and lethargy. A male sibling had previously died at 14 months of age from liver failure of unknown aetiology. Both of the current cases had mild hyperammonaemia with normal orotic acid, organic acid and argininosuccinic acid levels. Citrulline and arginine levels were normal or mildly decreased. One of the brothers was biopsied and had no detectable N-acetylglutamate synthetase activity and normal values for other enzymes of the urea cycle in liver. Treatment with a low-protein diet and
sodium
benzoate/
sodium
phenylacetate resulted in near normal blood ammonia levels, except during viral illness. Subsequent neurological development has been normal to mildly delayed. These patients differ from those previously described with N-acetylglutamate synthetase deficiency in that their presentation and subsequent course were relatively benign.

A long-term follow-up study of 42 patients with West syndrome treated with high doses of
sodium
valproate is presented. Control of the hypsarrhythmic EEG pattern was achieved after two weeks for over three-quarters of the patients with
sodium
valproate doses of 100 to 300mg/kg/day. Recurrence of hypsarrhythmia was observed most often in patients treated with doses lower than 200mg/kg/day. Other types of seizures appeared in half of the patients followed beyond two years of age. Monotherapy throughout follow-up was possible for 30 patients. Autism occurred in only one infant, and 12 achieved normal mental status. The most common side-effects were asymptomatic thrombocytopenia,
vomiting
and mild somnolence. Hepatic enzymes were not altered.

Soluble oral antacids are commonly used before anesthesia for cesarean section. The purpose of this prospective, single institution, randomized experimental study was to examine the relationship of oral administration of Bicitra (
sodium
citrate and citric acid) to the incidence of nausea and vomiting in patients undergoing elective cesarean section utilizing regional anesthesia, and to evaluate its effectiveness in neutralizing gastric acid. Eighty-six patients were studied (39 in a control group and 47 in a Bicitra treatment group) to ascertain if there was any difference with regard to height, weight, parity, gravity, age, race, incidence of heartburn with pregnancy, incidence of nausea with pregnancy, length of NPO status, preoperative systolic blood pressure (SBP), perioperative low level of SBP, and cumulative drop in SBP. Pearson chi square analysis showed no significant difference between the two groups for all variables or the incidence of nausea and vomiting. No significant difference was noted in the mean pH and volume of
emesis
of seven subjects analyzed using pooled t tests. After initial hypothesis testing was concluded, the sample was divided into two groups, those who experienced nausea and those who were free from nausea. The nausea group demonstrated a significantly greater cumulative decrease in SBP than did the non-nausea group. Larger patients (mean cube root weight index of 2.78) tended to become nauseated more frequently.

Dehydration, in childhood as in adulthood, may origin from an inadequate water ingestion or an excessive water elimination. Causes may be found in fever,
vomiting
, scalds, pulmonary hyperventilation, diabetes. Water loss during acute diarrhea in children can be even 6-7 times higher in comparison with an healthy child. Together with water, electrolytes are lost. We differentiate dehydration in isonatremic d. (70% of cases), hyponatremic d. (10%) and hypernatremic d. (20%) basing on
Sodium
loss. Important dehydration causes severe clinical symptoms as shock, renal and cardiocirculatory failure, convulsion, coma. Symptoms at the central nervous system level derivate both from hyperosmolarity in brain cells and from thrombosis or hemorrhages in subdural sites. Dehydration, following acute diarrhea, is slight when weight loss is lower than 5%. The child health conditions still remain good. Dehydration become moderate if weight loss reaches 5% and the child starts suffering. When the weight loss reaches 10%, dehydration is now severe and circulatory deficiency becomes evident. When it is higher than 10%, prognosis is very severe and shock and coma may be observed. In the present work, we illustrate the different ways of rehydration after acute diarrhea. Initially, oral rehydration must be established with one of the oral solutions, differing each other for amount of electrolytes and glucose. Recently, a new solution, "supersolution", has been presented differing from the other ones for electrolytes concentration and for the presence of rice starch instead of glucose. In most cases of diarrhea, oral rehydration appears adequate but sometimes an intravenous rehydration becomes necessary, e.g. in case of
vomiting
, CNS depression and in any case of severe gastroenteric symptomatology.(ABSTRACT TRUNCATED AT 250 WORDS)

A 36-year-old woman had for two months experienced progressively more marked diffuse abdominal pain, at times colicky, as well as nausea,
vomiting
and severe constipation. In addition, paraesthesias and motor weakness developed in the thighs. This was accompanied by a normochromic, normocytic anaemia with a haemoglobin concentration of 9.6 g/l. A short time later her mother and daughter also fell ill with similar symptoms. After symptomatic treatment had failed, secondary coproporphyria due to lead poisoning was found. The poisoning had resulted from criminal contamination of food, especially of cocoa powder, with lead acetate. Raised lead concentrations in serum were found in two other members of the family. In all the patients treatment was undertaken with
sodium
calcium edetate (20 mg/kg body-weight) in several three-day cycles, achieving a gradual fall in serum lead concentration. When the level had fallen to below 4 mumol/l the symptoms disappeared. Below 3 mumol/l porphyria was no longer demonstrable and the anaemia regressed. It is pointed out that, as lead poisoning may be fatal, it should be considered in the differential diagnosis of acute abdominal colic of unclear cause.

A 6-month-old infant suffering from cystic fibrosis is reported. In spite of an apparently appropriate treatment and in absence of respiratory infection, the patient showed progressive anorexia, intermittent
vomiting
and weight loss. These non-specific signs and symptoms could all be explained by metabolic alkalosis and disappeared immediately after oral supplementation with
sodium
and potassium chloride. This unusual metabolic complication should be searched for in every cystic fibrosis infant with unexplained anorexia and failure to thrive.

A 37-year-old chronic alcoholic female was admitted with epigastric pain, complete anorexia,
vomiting
and diarrhoea. She was dehydrated, and had polypnoea. Laboratory investigations revealed severe metabolic acidosis (pH 7.14) with a major anion gap (37.4 mmol.l-1), and ketone bodies in blood and urine. Blood glucose concentration was 6.1 mmol.l-1, there was no glycosuria. Rehydration (2 l.day-1 of 5% glucose) together with
sodium
bicarbonate (500 ml of 1.4%
sodium
bicarbonate over the first four hours) normalized the pH (7.37). The ketone bodies disappeared on the following day. During the acute illness, were found high blood levels of glucagon and low levels of insulin. The diagnosis of alcoholic ketoacidosis, the pathogenesis of which remains unknown, is discussed.

Acute methanol intoxications are infrequent among accidental or suicidal intoxications today. The characteristic findings are illustrated by a review. Mainly, the methanol metabolites formaldehyde and formic acid are of toxicologic importance and cause the dominant central nervous and ocular symptoms. The principal therapeutic procedures include gastric lavage, induced
vomiting
, titrated correction of acidosis with
sodium
bicarbonate, administration of ethanol, folic acid and, especially, the secondary detoxication with peritoneal--or better--haemodialysis. The therapeutic measures must be started quickly and carried out consequently to improve the prognosis of methanol intoxication and to decrease the frequency of serious late complications like ophthalmologic and neurologic lesions. Our own medical management is described by a case report treated successfully.
