The symptoms and signs of 51 patients with a history of scorpion sting were studied. Acute pulmonary oedema with peripheral circulatory failure due to myocarditis developed in 10. Pulmonary oedema appeared within thirty minutes to ten hours after the sting. 5 out of 7 male patients in whom pulmonary oedema subsequently developed presented with priapism. Profuse sweating, mydriasis, vomiting, and peripheral circulatory failure were also seen, and, in 1 patient, the clinical picture was suggestive on pancreatitis. The remaining 40 patients has severe local pain only and no subsequent cardiac manifestations. There appears to be a positive correlation between occurrence of priapism in a male and the later development of cardiac manifestations after a scorpion sting.

A case is described in which unusually high doses of intravenous ritodrine were used for 6 weeks to postpone premature labour. Treatment was complicated by tachydysrhythmias and pulmonary oedema. Epidural analgesia was used successfully for pain relief during labour and Caesarean section. The pathophysiology is discussed.

Cases of fatal poisoning with cupric compounds are relatively rare in everyday life and are not covered much in forensic literature. A case was encountered of fatal poisoning with a blue vitriol solution introduced into the uterine cavity in order to interrupt a pregnancy. A 39-year-old woman brought to the hospital by ambulance complained of pain in the lumbar region and profuse bloody genital discharge, which had appeared 3 days earlier. She believed she was 2 months pregnant and denied artificial interruption of the pregnancy. Upon examination, her condition was grave: a weak pulse of 80; blood pressure 100/60. The abdomen was soft, the liver and spleen not enlarged. Pasternak symptom was negative. The uterus was soft, painless and enlarged to 9 weeks of pregnancy. The uterine cervix was clean, the orifice closed. Discharge was profuse and bloody. The diagnosis was that she was 9 weeks pregnant and had a missed criminal abortion. Scraping out the uterus and corresponding therapy to control bleeding were ineffective. An operation was performed--extirpation of the uterus. However, despite the steps taken, the bleeding did not stop, and the patient's condition continued to worsen. 10 hours after being admitted to the hospital, she died. During forensic investigation, diffused, violet-colored cadaverous spots were discovered. Extensive subcutaneous hemorrhage was detected around the areas of injection. The skin covering was edematous; when pressed with a finger, areas of depression remained. There was about 250 ml of watery blood in the abdominal cavity. Internal organs were anemic. There were multiple subpleural, subepicardial, subcapsular, intraorgan and intramuscular micro- and macro-punctate hemorrhages; bleeding into the mucosa of the gastrointestinal tract and urinary tracts; and cerebral and pulmonary edema. Forensic histological examination showed acute circulatory disturbance with perivascular and peridiapedetic hemorrhage; concentrations of aggregated and hemolyzed erythrocytes in the small vessels and capillaries; cerebral, pulmonary and stromatic edema. In the kidneys there was coaugmentation of renal glomeruli; epithelial necrosis of part of the coiled ducts; lower epithelium in places had pigment grains; primarily in openings of straight ducts there were pigment cylinders; extreme plethora of the surrounding area, and infiltration from annular cells and polynuclears. Forensic chemical analysis showed 12.8 mg of copper; 6.6 mg in the uterus and 5.6 mg in the kidneys. From data obtained it can be concluded that the patient died from cupric compound poisoning, complicated by interruption of the pregnancy and uterine hemolytic hemorrhage. It was later established that during the month before being admitted to the hospital the patient introduced a solution of blue vitriol into the uterine cavity to interrupt the pregnancy.

Naloxone (Narcan) is generally considered to be a narcotic antagonist devoid of pharmacologic activity except for its reversal of opioid (narcotic) effects. Case reports indicate that naloxone in its role of narcotic antagonist may induce hypertension, pulmonary edema, atrial and ventricular arrhythmias, or cardiac arrest in certain patients, particularly those with pre-existing cardiac abnormalities. These adverse effects of naloxone may be due to extreme sympathetic nervous system activity resulting from the reversal of narcotic analgesia, an effect of the drug on peripheral or central opioid receptors or a drug interaction with other anesthetic agents. Any patient given naloxone, particularly in the presence of surgical pain, should be closely monitored for adverse cardiovascular effects.

Simple criteria were used to select a low-risk group of patients after acute myocardial infarction. The criteria depended on the presence or absence of diabetes, pulmonary oedema, serious rhythm disorders, and recurrent cardiac pain. Patients in the low-risk category with a suitable home environment were discharged from hospital after five to seven days (mean 6.2 days); they constituted 47% of the 267 hospital survivors over 18 months. Mortality in the selected patients was 2.4% at six weeks and 7% at one year. Most complications preventing early discharge were identified on the first day. Provisional selection for a short hospital stay was made after two days, and 76% of those judged suitable at 48 hours remained free of complications. Early selection of a low-risk category is justifiable and of practical value, though subsequent events will delay discharge for some patients. All patients who died in hospital or within two weeks after infarction had developed overt complications by the end of the fourth day. The results suggest that a policy of hospital discharge after four days would be justifiable for a low-risk group selected by the present criteria.

Radioimmunological determination of serum myoglobin in 115 patients is reported. Frankly pathological values were noted in 45/55 subjects with a diagnosis of acute myocardial infarct, whereas 7 displayed only a slight rise, and the remaining 3 proved to be false negatives. Pathological values were observed only 2 hr after the commencement of pain, with maxima after 6-20 hr (mean 10 hr). Values returned tonormal 37 hr after the onset of pain. In patients with angina pectoris, myocardial ischaemia, and pulmonary oedema not due to acute infarct, there was only a slight increase in serum levels, while pathological values were never noted in patients with precordial pain of non-cardiac origin.

The maternal mortality rate associated with eclampsia ranges from 100 to 6000 per 100,000, and the perinatal mortality rate ranges from 150 to 400 per 1000. Both eclampsia and its preceding condition, pregnancy-induced hypertension, occur in varying degrees in different parts of India. The warning signs of imminent eclampsia are 1) systolic blood pressure of 160 mmHg or more on two occasions six hours apart when the patient is on bed rest; 2) proteinuria of 5 g or more in 24 hours or 3 + or more by semiquantitative assay; 3) oliguria or anuria; 4) cerebral or visual disturbances; 5) pulmonary edema or cyanosis; and 6) epigastric/right hypochondriac pain, impaired liver function, and thrombocytopenia and coagulation disorders. Eclampsia is classified as the acute fulminating type, which can occur without warning, and the insidious type. Most cases (61%) show onset of eclampsia during the prenatal period. Treatment of eclampsia involves 1) control of convulsions (through an injection of magnesium sulphate or diazepam or the intravenous administration of phenytoin); 2) correction of hypoxia and acidosis; 3) a gradual lowering of blood pressure with hydralazine hydrochloride, nifedipine, atenolol, labetalol, oxprenolol, or metoprolol); and 4) steps to effect delivery. Diagnosis of HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) requires a complete blood count, blood film for platelet count and red blood cell fragmentation, and a coagulation screen for diagnosis of disseminated intravascular coagulation. Efforts to induce delivery in cases of prenatal eclampsia can take place 12-24 hours after convulsions have stopped. There is no reason to prolong pregnancy in the interests of the fetus, and in some cases Cesarean section may be required. Adequate prenatal care should allow the identification of almost every potential case of eclampsia and allow the prompt treatment of pre-eclampsia or termination of pregnancy when necessary. Medical staff must receive proper training to diagnose pre-eclampsia and treat the condition.

Methadone is a synthetic opioid with excellent oral bioavailability, variable, but long duration of action and extremely low cost. Our group has found that methadone is well tolerated in patients with difficult pain syndromes who are receiving high dose opioids. However, because of high interpersonal variation in bioavailability and the long duration of action of this drug, treatments should be highly personalized. We report on a 61 year old cancer patient who was switched from 84 mg/day of subcutaneous hydromorphone to 90 mg/day of oral methadone. On this dose, she developed respiratory depression and non-cardiogenic pulmonary edema that responded to subcutaneous naloxone and methadone discontinuation. Our findings suggest that standard equalanalgesic tables are unreliable for methadone titration. Switchovers should take place slowly and in a personalized fashion.

Our aim was to assess clinically whether there was any benefit in adding a single dose of sublingual nifedipine (a slow calcium channel blocker) to prazosin in the management of the cardiovascular manifestations of envenoming by the Indian red scorpion (Mesobuthus tamulus). A total of 163 patients stung by this species was admitted to hospital at Mahad between January 1991 and October 1993. Cardiovascular abnormalities were hypertension (59), of whom 42 had bradycardia and 17 had tachycardia; pulmonary oedema (14), of whom eight had hypertension and six hypotension; supraventricular tachycardia (eight), of whom three had hypotension and one died. Of the remaining patients, 78 demonstrated severe excruciating local pain at the site of sting but had no systemic involvement. Nineteen patients with hypertension and tachycardia were given a single dose of sublingual nifedipine plus prazosin on admission, then prazosin alone repeated 6 hourly. Five patients with massive life-threatening pulmonary oedema recovered after being given intravenous sodium nitroprusside. Prazosin alone helped to alleviate cardiovascular manifestations in the remaining 52 victims. One patient was admitted in a deep coma, 12 hr after the sting, and died. Eight victims whose blood pressure had been controlled in hospital by nifedipine plus prazosin developed acute pulmonary oedema necessitating additional doses of prazosin for recovery. Fifty-two victims treated with prazosin alone did not develop pulmonary oedema and the drug appeared to hasten the recovery. In the presence of high blood pressure, tachycardia, a murmur and impending myocardial failure, nifedipine appeared to contribute to cardiopulmonary instability and to augment myocardial oxygen consumption. In this situation calcium channel blockers should probably be avoided.

A total of 52 patients with myocardial infarction have been examined. The patients have been subjected to HBO procedures. 40-62 min sessions with a working pressure of 0.3-1.1 atm were performed. The optimal pressure during the first days is 0.3 atm with a gradual increase to 0.7 atm. It is important to prepare the patient before the session with the end in view to achieve hemodynamic normalization and pain relief and to ensure a possibility of coronarolytic intake during the session. By session 4-5 hypercapnia and hypoxia, hyperventilation syndrome were eliminated, hemodynamic and respiratory parameters normalized, and immunity recovered. Only in one case a session had to be interrupted because of pulmonary edema recurrence. In 7 patients usual complications which were easily relieved have been observed. HBO shortened the patients' stay in an intensive care unit by 1.6 days and decreased lethality by 9.5%.
