Defects in mitochondrial beta-oxidation may result in severe metabolic crisis after metabolic stress. The combination of hypoketotic hypoglycaemia and concurrent collapse of mitochondrial metabolic function may be very similar to that in Reye syndrome. Chronic effects on cardiac and skeletal muscle may be seen in some patients with defective long-chain fatty acid oxidation. Less common symptoms include peripheral neuropathy, pigmentary retinopathy, and failure to thrive with recurrent diarrhoea or vomiting. Collectively, such disorders are relatively common and their association with sudden infant death leads to a considerable demand for laboratory investigation. Currently the laboratory methods available are not capable of dealing with this demand in a rational and cost-effective manner and it is necessary to have careful clinically- and pathologically-based selection procedures if a useful service is to result.

Adverse reactions to radiopharmaceuticals are comparatively few in number. Various estimates quote an incident rate of 1 to 6 reactions per 100,000 injections. Other figures quoted are 1 in 800 for the bone-seeking radiopharmaceutical methylene diphosphonate, and 1 in 400 for the lung visualisation agent macroaggregated albumin. The very low numbers of reported adverse effects probably reflect the tiny amounts of material which are used in the formulation of radiopharmaceuticals. Adverse reactions to radiopharmaceuticals are usually mild and transient and require little or no medical treatment. A few reactions involve respiratory or circulatory collapse or loss of consciousness. Several fatalities have been reported with the liver scanning agent 99mTc (technetium 99m)-albumin colloid. Clinical manifestations may be categorised under the headings of vasomotor effects i.e. faintness, pallor, diaphoresis or hypotension, and anaphylactoid effects such as nausea, dermographism, wheezing, bronchospasm, erythema and pruritus. The most prominent group of radiopharmaceuticals that have been reported to produce adverse events are the diphosphonates, which are used for scanning the skeleton. Typical diphosphonate reactions include erythema (especially over the extremities), nausea, vomiting and malaise. The onset of reaction is usually 2 to 3 hours after injection. The second group of radiopharmaceuticals which give rise to adverse events are the colloids, which are used for liver and spleen scintigraphy. Typical colloid reactions include pallor, nausea, flush and pulse changes. Adverse events may also occur as a result of the patient's medication interfering with the disposition of the radiopharmaceutical. Although not usually hazardous or dangerous, such events may be so pronounced that a marked deviation in the expected pharmacokinetics may occur. Drug interactions can be conveniently categorised under the headings of unusual handling of the radiopharmaceutical because of pharmacological action, genuine in vivo interaction between the medication and radiopharmaceutical, drug-induced disease and interaction between the radiopharmaceutical and catheters or syringes. The most serious drug interactions are those where the patient is taking cortisone or cytotoxic agents prior to tumour scintigraphy. Other important effects occur in patients undergoing bone scanning who are receiving iron preparations. Nifedipine has been reported to produce quite severe problems in scanning, including difficulties in the radiolabelling of red cells (for cardiac scintigraphy), and other effects where the drug appears to prevent the transport of bone-seeking materials into the skeleton. Many drugs alter hormonal status and these effects may produce marked deviations from the expected biodistribution. Diethylstilbestrol (stilboestrol), digitalis, gonadotrophins, phenothiazines and cimetidine all increase estrogen levels in high doses.(ABSTRACT TRUNCATED AT 400 WORDS)

The medical records of five dogs diagnosed with infectious pericardial effusion were reviewed. Clinical signs included anorexia, depression, respiratory distress, abdominal distension, collapse, coughing, and vomiting. Anemia and leukocytosis were present in three dogs. Grass awn migration was confirmed as the cause of the pericardial effusion in two dogs and suspected in the other three. Surgery, followed by continuous chest drainage, and appropriate antibiotic therapy was the treatment in four dogs. Chest drains were removed within 4 days of surgery. One dog did not have chest drainage after surgery. Antibiotic treatment was continued for up to 6 months. The dogs were monitored postsurgically for a period ranging from 3 to 24 months. All dogs recovered well without apparent complications.

We present a case of acute lethal poisoning by oil of "epazote" (oil of chenopodium), in a 2 y 9 m female. The volatile oil was administered according to the advice of a "curandera" (female healer), in a total quantity of 40 ml. Clinical features of the poisoning were: vomiting, deep coma, seizures, mydriasis, apnea, metabolic acidosis, neurogenic shock and death. The EEG suggested a diffuse encephalopathy, the CT scan with an image of severe brain edema and ventricular collapse. Relevant postmortem findings were brain edema and neuronal necrosis, pneumonia, enteritis, pericholangitis, mild pancreatitis and tubular necrosis. The phytochemical analysis of volatile oil identified ascaridol, the main active compound of the chenopodium herbs, in a quantity of 39 mg/ml (1,560 mg in the dose administered), and Chenopodium graveolens as the plant employed to prepare it. According to the age of the patient, 60 mg of ascaridol would be the recommended dose formerly used in the treatment of parasitic disease. Thus 1,560 mg was 26 times higher than the recommended dose, and exceeded by 56% the dose of 1,000 mg reported as lethal in humans.

While cholera is not endemic in Taiwan, the number of imported cases is increasing. We report a 59-year-old Taiwanese male who developed severe diarrhea and vomiting, two days after returning from Bali. The patient admitted drinking a beverage with ice purchased from a street vendor. On admission he was weak and dehydrated. The patient suffered from hypovolemic shock and acute renal failure. Elevated creatine phosphokinase indicated rhabdomyolysis. Fluid replacement with Ringer's lactate solution was instituted. Dyspnea and pulmonary edema developed, and hemodialysis was begun to remove excess fluid due to decreased urinary output. Isolation of Vibrio cholerae O1 from stool confirmed the diagnosis of cholera, and doxycyline was begun. The patient's condition stabilized, with increased urinary output, and resolution of diarrhea, vomiting and dyspnea. Cholera, although rare in Taiwan, can be lethal if left untreated. Rapid intervention with fluid replacement is essential to prevent hypovolemic shock and circulatory collapse in severe cases.

The incidence of dengue increased sharply in Martinique from the end of 1995 into 1996. Virological tests performed jointly on 36 serum samples by the Pasteur Institute in French Guyana and the Center for Disease Control in Puerto Rico led to identification of serogroups 1, 2, and 4 for six dengue virus. Between January 1995 and December 1996, the Departmental Hygiene Laboratory of Martinique carried out screening tests to detect specific IgM by the immunocapture method (MAC ELISA) in patients with suspected dengue. Results were positive in 701 of the 2,143 patients tested (32.7%). Symptoms were studied in 421 of these positive cases. The most frequent presentation was a flu-like syndrome with hyperalgia. Nausea, vomiting, joint pain, and retroocular pain were frequent. At least one clinical sign of coagulation disturbance was noted in 83 patients (19.7%). Dengue hemorrhagic syndrome was diagnosed according to the criteria of the World Health Organization in six patients including one who developed circulatory collapse and died. This fatality was the first to be reported in Martinique. The incidence of typical dengue as well as of the hemorrhagic form is probably underestimated in Martinique because specific serological tests are not routinely requested and application of WHO criteria for diagnosis of hemorrhagic forms is often impractical.

A 32-year-old woman was admitted with a diagnosis of impending premature delivery. In the 37th week of pregnancy, vaginal examination was performed. After ten minutes, vomiting, whole body flushing, and cold sweat appeared suddenly. Because fetal heart rate became 60-70 beats.min-1, emergency caesarean section was scheduled. When she arrived at the operating room, blood pressure was 75/45 and heart rate was 122 beats.min-1. Five minutes later, anesthesia was induced with thiopental and vecuronium, and operation was instituted concomitantly. After the delivery, pentazocine and midazolam were administered. During the operation, premature separation of normally implanted placenta or pressed cord was not observed. Hydrocortisone was administered for circulatory collapse. Gabexate mesilate was administered for the prevention of DIC. The scratch test, performed ten days later, revealed that latex was positive but lidocaine was negative. Therefore, it was concluded that anaphylaxis induced by latex gloves caused shock after internal examination.

Laparoscopy employs highly technical equipment, and the surgeon needs special training in the technique. He should master in-depth knowledge of the use of optics, electrical principles, gas under pressure, and the physiologic changes that occur when carbon dioxide is placed in the abdominal cavity. Above all, the surgeon must adhere rigidly to guidelines for appropriate technique, and deviation will most assuredly result in complications and even death. General surgery application of laparoscopy followed a wealth of medical experience from gynecological laparoscopies, which declared the technique as safe, reduced hospital stay with little pain and disfigurement. Laparoscopic cholecystectomy started to enjoy ever increasing popularity. It retained the advantages of shorter hospital stay, more rapid return to normal activities, less pain, small incisions and less postoperative ileus compared with the traditional open cholecystectomy. Soon many procedures were done using this new technique in adults and children. Anesthesia for laparoscopy has been established with a broad usage of agents and techniques. General anesthesia using balanced anesthesia technique including intravenous induction agents like: thiopentone, propofol, etomidate, and inhalational agents like nitrous oxide, isoflurane, desflurane, has been reported. Variety of muscle relaxants including succinylcholine, mivacurium, atracurium, vecuronium aiming at rapid recovery and cardiovascular stability. Total intravenous anesthesia using agnets like propofol, midazolam and ketamine, alfentanil and vecuronium has been reported also for outpatient laparoscopy. Epidural anesthesia was considered as safe alternative to general anesthesia for outpatient laparoscopy without associated respiratory depression. As for pain relief, many methods have been used. The pain mechanism is variable and analgesia requirement is less than those of open surgery. Cited complications include pneumothorax, cardiovascular collapse, surgical emphysema and pneumo-peritoneum complications. Among the implication for anesthesia care, the importance of preoperative monitoring, careful positioning and observation during the insufflation of carbon dioxide. The drive to have short term admission to hospital would make it imperative to use short acting rapidly eliminated anesthetic drugs, avoidance of vomiting and pain by proper use of modern anti-emetics and NSAID to help in avoidance of narcotics or reduction of the requirement.

A 45-year-old woman had pyrexia, headaches, collapse and hyponatraemia. Intracerebral abscess, bacterial meningitis and subarachnoid haemorrhage were excluded. She was given intravenous antibiotics and gradually recovered. One month later she was readmitted with diplopia, headache and vomiting. Serum sodium was low (107 mmol/l) and a diagnosis of inappropriate ADH secretion was made. MRI scan showed a suprasellar tumour arising from the posterior pituitary gland. A skin rash gradually faded. Serum cortisol, prolactin, gonadotrophins and thyroid hormone levels were low. A pituitary tumour was removed trans-sphenoidally, she had external pituitary radiotherapy, and replacement hydrocortisone and thyroxine. She was well for 12 months when she developed progressive weakness and numbness of both legs. Examination suggested spinal cord compression at the level of T2 where MRI scanning showed an intradural enhancing mass. This spinal tumour was removed and her neurological symptoms disappeared. Nine months after this she developed facial pain and nasal obstruction. CT scan showed tumour growth into the sphenoid sinus and nasal cavities. A right Cauldwell-Luc operation was done and residual tumour in the nasal passages was treated by fractionated external radiotherapy and Prednisolone. Histological examination of the specimens from pituitary, spinal mass, and nasal sinuses showed Rosai-Dorfman disease, a rare entity characterized by histiocytic proliferation, emperipolesis (lymphophagocytosis) and lymphadenopathy. Aged 48 she developed cranial diabetes insipidus. Although Rosai-Dorfman syndrome is rare, it is being reported with increasing frequency, and should be borne in mind as a possible cause of a pituitary tumour.

A 6-week-old boy was referred with a generalized bullous rash since birth. Examination revealed bullous mastocytosis with initially no evidence of systemic involvement. Hepatosplenomegaly was noted at 6 months, and at 12 months he was found to have generalized lymphadenopathy. He developed bouts of vomiting associated with increased blistering. At 17 months he had sudden collapse following a brief bout of vomiting and was apneic and asystolic on arrival at the emergency department. The cause of death was attributed to massive hypotension secondary to mast cell degranulation. Although childhood mastocytosis has a favorable course in general, the subset of children with congenital bullous mastocytosis is at higher risk of sudden death and a more guarded prognosis should be given.
