A case of intravenous labetalol in the treatment of a resistant hypertensive emergency is reported. Although there have been several reports of the use of oral labetalol in resistant hypertension, no intravenous administration in hypertensive emergency resistant to other drugs has been reported to date. A 36-year-old black female with BP of 270/160 mm Hg with complaints greater than one month's duration of dizziness, severe headaches, blurred vision, shortness of breath, vomiting, palpitations, flushing, agitation, diarrhea, weakness, and weight loss, was treated successfully with intravenous labetalol after she failed to respond to other established parenteral antihypertensive drugs. The patient received labetalol 20 mg iv bolus, and then 20 mg every ten minutes until a cumulative dose of 200 mg was attained. Labetalol produced a prompt but smooth reduction in BP without any reflex tachycardia or other adverse effects. Intravenous labetalol may be safe and effective for the management of rapid BP control in hypertensive emergencies resistant to other parenteral antihypertensive agents.

A patient with malignant ascites refractory to conservative and conventional therapy underwent peritoneovenous shunt. The shunt provided palliation for 7 months with relief of nausea, vomiting, and anorexia and with decrease of weight and abdominal girth. There was no need for repeated paracenteses, which had been required before shunting. The patient's strength increased. However, increasing shortness of breath developed approximately 6 to 7 months after insertion of the shunt. The shunt was associated with extensive metastatic dissemination of peritoneal mesothelioma to both lungs. It is suggested that peritoneal mesothelioma is a contraindication for peritoneovenous shunt.

Twenty-four patients were evaluated in a non-randomized study to assess the effectiveness of dibromodulcitol (DBD) in Stage IV melanoma. Patients received 100 mg/m2 of DBD orally for 35 days. The dose was escalated to 130 mg/m2 and then to 160 mg/m2 if no significant hematologic toxicity occurred. There were no objective responses, including six patients who had had no prior chemotherapy. Five patients (21%) remained stable. Median survival was 151 days. Survival favored females, nonvisceral involvement pretherapy, and patients with a disease-free interval (DFI) of greater than 1 year. None of these advantages was statistically significant. Toxicity was predominantly hematologic, but nausea, vomiting, shortness of breath, and diarrhea were also seen. Oral DBD, using this dose and schedule, does not appear efficacious in advanced disseminated melanoma.

Praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a]++ +isoquinolin- 4-one, EMBAY 8440, Biltricide) has been used in 4853 patients with Opisthorchis viverrini infection. 786 patients were treated as inpatients with extensive clinical evaluation and the rest were out-patients. A cure rate (evaluated with 5 faecal samples) of 100% was obtained in groups given 6 X 25 mg/kg on 2 days and 3 X 25 mg/kg on 1 day, while in groups given 2 X 25 mg/kg, 1 X 25 mg/kg and 1 X 40 mg/kg all on 1 day the cure rates were 88, 44 and 91%, respectively. With one sample evaluation the parasitological cure rate was 96% in further 96 patients excreting the geometric mean (GM) of 5394 eggs per gram (EPG) and receiving 1 X 40 mg/kg. Another 68 patients with an egg output of 26044 (GM/EPG) and treated with 1 X 50 mg/kg showed a cure rate of 97% by similar evaluation. Side effects were mild and transient and were more frequent in higher dosage groups. They included anorexia, nausea, vomiting, abdominal pain, epigastric pain, rumbling in the abdomen, diarrhoea, lassitude, myalgia, headache, dizziness, sleeplessness, sleepiness, "hot sensation", shortness of breath, and skin rash in a few cases. Headache (30.7%) was most common in the 6 X 25 mg/kg group. In 53 patients with severe jaundice the side effects were similar. There was no evidence of toxicity. Remarkable was one patient treated with 1 X 50 mg/kg who expelled 5636 O. viverrini worms, most of which were elongated and damaged. When a single dose is prescribed it should be given at bed time to reduce the side effect of sedation.

Often patients in IMF are healthier, tend to be more independent, and have shorter hospital stays than many patients hospitalized for other reasons. This is by no means any indication that they do not require close assessment and skilled nursing care. While recovering from anesthesia, airway obstruction and vomiting are real dangers. Although wire cutters are a necessary safety precaution and a part of the legal standard of practice, nurses and patients should not rely solely on them in the incidence of shortness of breath or vomiting. Nurses and patients should know the proper technique for clearing the mouth and airway of a patient in IMF. Hemorrhage evaluation and secretion control also require skilled observation and assistance by the nurse. Patients in IMF benefit from a decrease in anxiety levels when they are educated in airway clearance, secretion control, comfort measures, and diet. The nursing care of patients in IMF is rewarding and challenging for many areas of nursing.

We evaluated the relationship of ritodrine concentration to several maternal variables and to fetal heart rate in 17 women who received the drug for inhibition of preterm labor. Ritodrine was measured by high-performance liquid chromatography with electrochemical detection. Ritodrine increased maternal and fetal heart rate and decreased serum potassium in a dose-related manner, but wide variability was noted between patients and within individual patients. Tachyphylaxis of the maternal heart rate response to continuing treatment with ritodrine was seen in at least seven women. Maternal blood pressure, serum glucose concentration, and frequency of uterine contractions were changed by ritodrine treatment, but the changes in these variables were not closely correlated to the concentration of ritodrine (r less than or equal to 0.30 in all cases). The maximal infusion rate and the concentration of ritodrine in maternal serum after 4 hours of treatment were significantly (p less than 0.001) correlated with the frequency of uterine contractions prior to treatment. Successful inhibition of labor was achieved with serum concentrations of 15 to 31 ng/ml in 10 of 17 women; in six of the other seven women, labor could not be inhibited in spite of serum concentrations of 90 to 146 ng/ml. Side effects, such as hypotension, vomiting, chest discomfort, and shortness of breath, were most commonly observed when the infusion rate and concentration of ritodrine were increasing.

A 26-year-old white male, radar operator, participated in a flight in a U.S. Air Force T33 jet trainer. The patient experienced nausea and vomiting followed by several episodes of retching during maneuvers of positive acceleration. Upon landing, he noted severe epigastric pain and shortness of breath. After 3 h of persistent symptoms, he presented to the base hospital's emergency department where he was diagnosed as having diaphragmatic herniation of abdominal viscera into the left hemithorax. At laparotomy, a large traumatic paraesophageal tear was discovered. The abdominal viscera were reduced and the defect repaired. The postoperative course was uncomplicated. The pathophysiology of blunt, nonpenetrating diaphragmatic herniation is discussed. Another mechanism for diaphragmatic rupture resulting from the forces of vomiting and acceleration is proposed.

A patient at 42 weeks of pregnancy called the emergency department complaining of painful uterine contractions for six hours. She was advised to come to the hospital immediately. An episode of vomiting caused a 60-minute delay in her arrival. Dyspnea, fatigue, and leg cramps developed. In the emergency department she was anxious, alert, and cyanotic. Fetal distress was diagnosed. Within 15 minutes the patient had bradycardic cardiopulmonary arrest. Resuscitation attempts and agonal caesarean section failed. Autopsy revealed massive pulmonary amniotic fluid emboli. Amniotic fluid embolus must be considered in the differential diagnosis of pregnant patients with complaints of shortness of breath and signs of shock with bradycardia.

Two children and 29 of 31 crew members aboard a grain freighter became acutely ill after inhaling the toxic fumigant phosphine; one child died. Predominant symptoms were headache, fatigue, nausea, vomiting, cough, and shortness of breath. Abnormal physical findings included jaundice, paresthesias, ataxia, intention tremor, and diplopia. Focal myocardial infiltration with necrosis, pulmonary edema, and widespread small-vessel injury were found at postmortem examination of the dead child. The surviving child showed ECG and echocardiographic evidence of myocardial injury and transient elevation of the MB fraction of serum creatinine phosphokinase. Illness was significantly associated with living or working amidships or on the forward deck areas of the vessel. Phosphine gas was found to have escaped from the holds through a cable housing located near the midships ventilation intake and around hatch covers on the forward deck. The outbreak illustrates the hazards associated with shipboard fumigation.

Untreated hyperthyroidism during pregnancy is associated with increased maternal and perinatal morbidity. Some features of this disease simulate preeclampsia, which may encourage delivery of the fetus. We report a case of poorly controlled hyperthyroidism associated with generalized seizures, where patient management was directed at a diagnosis of preeclampsia-eclampsia. Although the presence of eclampsia and marked hyperthyroidism is very rare, this case illustrates the importance of aggressive medical management of hyperthyroidism. A 17-year-old gravida was diagnosed with hyperthyroidism at 15 weeks' gestation. At 26 weeks' gestation, she was admitted to the hospital after noting edema of the upper and lower extremities, nausea, vomiting, shortness of breath, and a cough. At admission, she was hypertensive, tachycardic, and dyspneic. The patient was believed to have preeclampsia with pulmonary edema complicated by hyperthyroidism. We initiated magnesium sulfate therapy and administered several bolus doses of hydralazine, with little effect on blood pressure. Oliguria was noted, and a pulmonary artery catheter was inserted. Hours later, generalized seizure activity occurred, and a decision was made for abdominal delivery. Postoperatively, cardiovascular function stabilized. On postoperative day 3, we received the results of the thyroid function tests obtained at admission, which suggested a markedly hyperthyroid condition. Untreated or poorly treated hyperthyroidism may present a clinical picture similar to preeclampsia. In our case, both disease processes coexisted in their severest forms. It is possible, although completely unproven, that a relationship exists between poorly controlled hyperthyroidism and preeclampsia-eclampsia. More importantly, accurate diagnosis of hyperthyroidism should lead to prompt medical or surgical management, thereby decreasing maternal and perinatal morbidity.
