Postprandial antral hypomotility in patients with idiopathic nausea and vomiting.

The pathogenesis of idiopathic nausea and vomiting is poorly understood and could involve disorders of gut motility. The contractile activity of the stomach and small bowel was studied in 20 patients (seven men) with nausea and vomiting for longer than six months. None had previous gastric surgery, mechanical obstruction and metabolic causes were excluded. Fasting (four hours) and fed (up to two hours) contractile activity was recorded by a low compliance infusion system from the gastric antrum (four sites), the duodenum and the jejunum. Normal criteria were established in seven healthy controls. During fasting, from one to three (median 2) migrating motor complexes (MMC's) were present in patients and controls. Only two patients had contractile abnormalities during fasting. After a solid-liquid test meal, the contractility of the gastric antrum (quantified electronically as a cumulative motility index for 60 minutes) was significantly impaired in patients (p = 0.012). Six patients had normal qualitative and quantitative antral activity but two of them had 'phrase III-like fasting activity' in the small bowel after the test meal. Postprandial antral hypomotility was identified as a major abnormality in patients with unexplained nausea and vomiting.

Value of ultrasound in differentiating causes of persistent vomiting in infants.

A prospective study of abdominal ultrasound was undertaken in 100 consecutive infants who presented with a history of persistent vomiting aged 5 to 90 days. Each infant had a 'test feed' followed by an ultrasonographic scan of the pylorus at the cotside. On test feeding a palpable tumour was evident in 38 infants. On real time ultrasound using the criteria for diagnosing pyloric stenosis, these 38 infants as well as six others were documented as having pyloric stenosis. In the other 56 patients the vomiting settled in six and a barium examination was performed on the remaining 50. This confirmed gastro-oesophageal reflux in 46, two of whom had an associated hiatus hernia, one with a duodenal malrotation, and three were reported as normal. Ultrasound of the abdomen is an accurate, reliable, and rapid screening method to differentiate the causes of severe vomiting in infancy.

Protracted vomiting as the presenting sign of posterior fossa mass lesions.

Four patients with mass lesions of the posterior fossa experienced protracted vomiting as their only symptom for extended periods of time. The responsible lesions were a cerebellar tumour in two patients, a ventricular cysticercus in one patient, and a giant vertebral artery aneurysm in another. All four cases had compression or displacement of the floor of the fourth ventricle, where the "vomiting centre" has been located. The value of vomiting as a sign of a posterior fossa lesion is emphasised.

Vomiting as an ictal manifestation of epileptic seizures and syndromes.

Twenty-four out of 900 adult and children patients with epilepsy, were found to have vomiting during an ictus. All the 24 patients were children before puberty with a similar clinical pattern consisting of partial seizures which were mainly nocturnal. Ictal vomiting was always concurrent with other epileptic manifestations, more often deviation of the eyes and impairment of consciousness. The initial part of the ictus was short or prolonged for hours with frequent "marching" to hemi-convulsions and generalised seizures. Seventeen of the 24 children suffered from benign childhood epilepsies (BCE) with complete remission in long follow-up. A significantly higher association was found between ictal vomiting and the syndrome of BCE with occipital spikes (p less than 0.001) but not with centro-temporal spikes (p less than 0.2). The recognition of this association may have important theoretical implications. On clinical grounds, it may prevent unnecessary investigations and undue concern.

Chlorpromazine, placebo and droperidol in the treatment of nausea and vomiting associated with cisplatin therapy.

The use of cisplatin may be associated with severe nausea and vomiting. Two separate, randomized, double-blind trials, comparing the anti-emetic effect of chlorpromazine with placebo and chlorpromazine with droperidol, were conducted in patients receiving cisplatin for ovarian cancer. Chlorpromazine was statistically superior to placebo in the control of nausea and vomiting in those patients treated with chlorpromazine had significantly less nausea than with droperidol, but there were no other significant differences between chlorpromazine and droperidol. Toxicities of chlorpromazine and droperidol were similar. Chlorpromazine shows useful activity against cisplatin nausea and vomiting.

Clinical observations on postoperative vomiting treated by auricular acupuncture.

We studied the effect of auricular acupuncture on postoperative nausea and vomiting (PONV). One hundred female patients undergoing transabdominal hysterectomy were entered into the study. The patients were divided into two groups (auricular acupuncture treatment group and non-treatment group) in order to test the effectiveness of auricular acupuncture. There was no significant difference in age, weight, height or duration of anesthesia among the two groups of patients. There was a significant difference between the control and auricular acupuncture treatment groups in the incidence of vomiting 12 hours after surgery (68% and 30%, respectively, p < 0.01). No noteworthy side effects from treatment were observed. Auricular acupuncture is effective in reducing vomiting following transabdominal hysterectomy in female patients.

Effects of ganoderma lucidum extract on chemotherapy-induced nausea and vomiting in a rat model.

Chemotherapy is highly cytotoxic, causing a number of severe adverse effects such as nausea and vomiting. Herbal medicines, which can often be used on a daily basis for prolonged treatment, may be clinically beneficial. Ganoderma lucidum or Lingzhi mushroom has been recognized as a remedy in treating a number of medical conditions, including balancing immunity and decreasing drug-induced side effects. It has been shown that rats react to emetic stimuli, like the chemotherapy agent cisplatin, by increased consumption of kaolin, known as pica; and this rat model has been utilized to evaluate novel anti-emetic compounds. In this study, we evaluated the effects of a G. lucidum extract (SunRecome, the most commonly used Lingzhi mushroom extract in China) in attenuating cisplatin-induced nausea and vomiting in the rat pica model. We observed that intraperitoneal cisplatin injection caused a significant increase in kaolin intake at 24, 48, 72 and 96 hours, reflecting cisplatin's nausea and vomiting action. This cisplatin-induced kaolin intake dose-dependently decreased after 1, 3 and 10 mg/kg G. lucidum extract injection (p < 0.01). In addition, there was a significant reduction of food intake after cisplatin. The cisplatin-induced food intake reduction improved significantly after G. lucidum extract administrations in a dose-related manner (p < 0.01), suggesting a supportive effect of the extract on general body condition. Future controlled clinical trials are needed to evaluate the safety and effectiveness of this herbal medication.

Methylprednisolone versus metoclopramide for prevention of nausea and vomiting in breast cancer patients treated with intravenous cyclophosphamide methotrexate 5-fluorouracil: a double-blind randomized study.

The antiemetic efficacy and toxicity of methylprednisolone (MP) and metoclopramide (MTC) in prevention of nausea and vomiting in breast cancer patients receiving intravenous cyclophosphamide methotrexate 5-fluorouracil (CMF) chemotherapy has been evaluated in a double-blind trial. The two antiemetic drugs (MP vs. MTC) offered the majority of patients a similar complete protection from vomiting (76.5 vs. 66.7%) and nausea (82.4 vs. 81.8%), but in older patients MTC seems more efficacious than MP. Sedation was found more frequently (p = 0.02) in patients treated with MTC. In conclusion, in patients treated with CMF the use of MP as preventive therapy of nausea and vomiting is to be preferred to MTC due to its better tolerability, but in older patients MTC should be considered if MP fails.

Salivary factors in vomiting bulimics with and without pathological tooth wear.

The increased occurrence of dental erosion from self-induced vomiting in bulimia nervosa is not linearly associated with the frequency or the duration of vomiting. Possible changes in the buffering and lubricating role of saliva in bulimia nervosa and their relationship to erosion have not been previously investigated. Chewing-gum-stimulated salivary flow rate, pH, bicarbonate concentration and viscosity were compared between two groups of vomiting bulimics and with 10 healthy controls. One bulimic group (n = 9) had pathological tooth wear present according to the criteria of the Tooth Wear Index and the other bulimic group (n = 10) did not. The influence of salivary pellicle on enamel acid dissolution by perchloric acid was also assessed by an enamel biopsy method. Bicarbonate was measured in a Natelson microgasometer. Both the bulimic groups had mean initial 3-min flow rates and overall 9-min flow rates significantly lower (p < 0.01) than the healthy subjects. The mean pH values were not significantly different between the two bulimic groups or the control group. However, the mean bicarbonate concentration in both bulimic groups was significantly less (p < 0.01) than in the control group. The mean salivary viscosity of 7.4 centipoise (cP), measured by a DV1 Brookfield viscometer, was significantly greater (p < 0.05) in the pathological tooth-wear-present group than in the tooth-wear-absent group (4.5 cP) and the control group (4.1 cP). Slightly more calcium was released from the pellicle-free surface in both groups but this was not statistically significant, whilst the dissolved calcium in enamel biopsies was significantly lower (p < 0.05) in the tooth-wear-present group.

Amount of calories retained after binge eating and vomiting.

While caloric consumption during binge eating has been measured, it is not known how many of the calories are retained in the gastrointestinal tract after vomiting. In 17 normal weight bulimic patients, there appeared to be a ceiling on the number of calories retained after vomiting. That is, whether or not bulimic patients had small (mean = 1,549 kcal, SD = 505) or large (mean = 3,530 kcal, SD = 438) binges, they retained similar amounts of kilocalories (mean = 1,128, SD = 497, versus mean = 1,209, SD = 574, respectively) after vomiting.

L-carnitine administration reduces number of episodes in cyclic vomiting syndrome.

Patients with cyclic vomiting syndrome suffer from recurring episodes of severe nausea and vomiting. This paper presents 6 patients who responded to 1-carnitine administration. Average time between episodes was 1.7 months before carnitine administration and increased to 1.1 years after carnitine administration. Average dose of carnitine administered was 50 mg/kg. Oral carnitine may be useful to control the symptoms in patients with cyclic vomiting syndrome.

Psychogenic vomiting among female Asian migrants to the United Kingdom.

Three female Asian migrants to the United Kingdom presented with vomiting which was not of organic origin. Cultural, dynamic and other factors influenced the adoption of vomiting as a manifestation of distress. Non-organic vomiting should be evaluated in terms of its symbolism, gains, and communicatory function for the individual.

The prevalence of nausea and vomiting in pediatric patients receiving home parenteral nutrition.

We have observed that many home parenteral nutrition (HPN) recipients experience nausea, vomiting, or both during cyclic parenteral nutrition infusions. The current investigation was performed to determine the prevalence and course of these symptoms and effectiveness of therapeutic maneuvers. Eighty-nine recipients of HPN were contacted and 53 families (60%) responded. Thirty-five patients (66%) reported complaints of nausea, vomiting, or both associated with their HPN infusion. Patients with cancer (82%) or cystic fibrosis (83%) reported symptoms at similar rates, while patients with gastrointestinal disease (46%) reported symptoms less often (p < .05, chi-square). Within each diagnostic group, prevalence of symptoms did not vary with age. The majority of patients were symptomatic in the morning when being weaned or soon after completing the HPN infusion. Response rates to a variety of therapies were also similar. In conclusion, nausea and vomiting associated with cyclicHPN infusions appear to be common. The precipitating events and efficacy of interventions await identification and prospective evaluation.

Prevention of cisplatin-induced vomiting in patients with cancer. A pilot study with a multiagent protocol.

Forty patients receiving a total of 102 courses of cisplatin (CDDP)-based treatment were observed in the present study. The patients received an antiemetic prophylaxis with metoclopramide (6 mg/kg), dexamethasone (12 mg/m2), lorazepam (2.5 mg), promethazine (50 mg), and diazepam (10 mg). Complete protection from acute vomiting was obtained in 77.5% of patients during the first course, and partial protection (1 to 3 episodes of vomiting) was observed in 10.1% additional cases. Complete protection was achieved in 84.6% of males vs 57.1% of females. Patients at their first course of chemotherapy had 80% complete protection compared to 66.7% in those who received prior chemotherapy. No differences in the response rate between patients treated with high versus patients receiving low doses of CDDP were noted. The same pattern of response was observed in subsequent courses of therapy. Side effects were minimal (mild sedation in almost all the cases and hiccups in a few cases). No major extrapyramidal reaction was observed. The regimen used in the study showed good efficacy in preventing acute CDDP-induced nausea and vomiting. Moreover, the very low incidence of major side effects makes this protocol safe and recommendable in patients undergoing CDDP chemotherapy.

Antiemetic activity of oral lorazepam in addition to methylprednisolone and metoclopramide in the prophylactic treatment of vomiting induced by cisplatin. A double-blind, placebo-controlled study with crossover design.

AIMS AND BACKGROUND: It has been suggested that lorazepam has a definite role as an antiemetic drug in antiemetic cocktails. In this study we examined the antiemetic efficacy of metoclopramide (200 mg) and methylprednisolone (1000 mg) with or without lorazepam. METHODS: Sixty patients treated with cisplatin-containing regimens were entered into a randomized, double-blind study with cross-over. Lorazepam 2.5 mg or placebo were administered orally the evening before therapy and just after the beginning of fluid infusion for chemotherapy. Degree of nausea and number of vomiting episodes, together with somnolence, were recorded on a data flow sheet and visual-analogue scales. RESULTS: 100 cycles (50 patients) are evaluable. In 39 cycles there was no nausea and vomiting, in 74 cycles acceptable control of emesis was reached (0-2 episodes of vomiting), without significant differences among the two arms. However, nausea was shorter in lorazepam arm (p < 0.01), and 80% of the patients preferred treatment with lorazepam (p < 0.003). Anxiety was reduced in the patients treated with lorazepam (p < 0.4). CONCLUSIONS: Lorazepam improves tolerability to cisplatin-containing chemotherapy, mainly by influencing the psychological status of the patient and favoring the amnestic process.

Control of nausea and vomiting by granisetron in ovarian cancer patients treated with different cisplatin-based regimens.

AIMS: The study evaluated the safety and efficacy of granisetron as an antiemetic drug in ovarian cancer patients treated with cisplatin-based chemotherapy. STUDY DESIGN: Two groups of consecutive patients were considered: the first (Group A) with advanced disease, receiving 4-day cisplatin therapy in a 40 mg/m2 daily dose; the second (B), with minimal disease after radical surgery at high risk of recurrence, treated by single-day chemotherapy with a 90 mg/m2 dose. In both groups, 3.0 mg of granisetron was administered as a 10 min. intravenous infusion, 30 min. before cisplatin infusion. The treatment schedule included in all patients the administration of 125 mg i.v. of methylprednisolone 2 h before chemotherapeutic infusion. No further doses of granisetron were allowed within each 24 h study period for breakthrough nausea and vomiting. Assessment for nausea and vomiting was made at 24 h intervals through the 6-day study period for both groups using a diary card. RESULTS AND CONCLUSION: In group A, 25 patients were collected and evaluated; in group B, 25 were recruited and 13 evaluated. In both groups, excellent control of nausea and vomiting was achieved, since in group A we had a global major antiemetic efficacy of granisetron in 69.2% of patients (54.4% complete control and 14.8% major control); in group B, global major efficacy was present in 83.3% of cases (31.6% complete control and 51.7% major control). The antiemetic effect in the days following antiblastic treatment lasted longer in group A.

Oesophageal rupture in a patient with postoperative nausea and vomiting.

Rupture of the oesophagus (Boerhaave's syndrome) is a rare complication of forceful or suppressed vomiting. Postoperative nausea and vomiting is common but does not usually lead to life-threatening complications. A case of oesophageal rupture in a man who experienced postoperative nausea and vomiting after an uncomplicated procedure is described in this report. Delayed diagnosis mandated conservative treatment. The clinical presentation, diagnosis and management of oesophageal rupture is discussed.

The effect of premedication on the incidence of postoperative vomiting in children after E.N.T. surgery.

The influence of premedication and intraoperative narcotic administration on the incidence of vomiting after E.N.T. surgery was studied over a six-month period in 596 children. A high incidence of vomiting was found after intramuscular papaveretum and hyoscine and after oral diazepam. Oral trimeprazine tartrate was associated with a low incidence of vomiting and was found to have an anti-emetic effect when an opiate analgesic was administered after induction of anaesthesia.
