Using metronidazole in oral dosages of 1.5 to 2 g daily, we treated 13 adults who had anaerobic pleuropulmonary infections, including 11 with lung abscess, one with necrotizing pneumonia, and one with thoracic empyema. Five patients (four with lung abscess and one with necrotizing pneumonia) were cured. The lung abscesses of 5 patients did not respond. For 3 patients (one with epigastric distress who refused metronidazole, one with undrained empyema, and one who died while receiving metronidazole), therapy could not be evaluated. Side effects included leukopenia (2 patients), leukopenia and neutropenia (one), neutropenia (one), dark urine (two), bitter taste (two), and epigastric distress (one). In light of our findings, metronidazole is not uniformly effective in the treatment of anaerobic pleuropulmonary infections.

Cresol, a commonly used disinfectant, may cause gastrointestinal corrosive injury, central nervous system and cardiovascular disturbances, and renal and hepatic injury following intoxication. We report a case of acute severe cresol poisoning after a suicide attempt with ingestion of a cresol-soap solution used as a toilet disinfectant. A 44-y-old male was found unconscious after ingesting 300 ml of 50% cresol-soap solution. Endotracheal intubation, gastric lavage and activated charcoal were given immediately which reversed his conscious. He had dermal burns, esophageal and gastric erosion, pneumonia, mixed metabolic acidosis and respiratory aklalosis, renal and liver function impairment, leucocytosis and dark urine. Acute renal failure and hemolysis developed, but he recovered after hemodialysis and intensive supportive care. Urine levels of p-cresol, m-cresol, o-cresol and phenol were respectively 2083, 2059, 125 and 68 mg/g creatinine at 7 h post-ingestion. Though the amount cresol claimed ingested by the patient (150 g) far exceeded the reported lethal dose (30-60 g), and multiple complications developed after massive ingestion, this patient recovered. The renal, pulmonary and hematological effects in this patient might have resulted from the direct toxicity of cresol and its metabolites.

The experience of 30 porphyric crisis is reviewed in 25 patients attended since 1967: 21 patients had 1 crisis, 3 had 2, and 1 had 3 of these episodes. In all patients, porphyria was diagnosed in relation to one crisis, even though many of them had family histories and/or previous clinical symptoms of this disease. There was clear predominance (80%) of women, but they are also a majority among acute porphyrias. The most frequent symptoms were: abdominal pain, tachycardia, dark urine, neurological and psychiatric alterations and arterial hypertension. The neurological alterations required the use of a respirator in 9 crisis (33%), which was maintained in 2 patients during 4 months. In 6 crisis (20%) there were no neurological symptoms. Among laboratory tests, hyponatremia was notable for its frequency (53.4%) and intensity. Increase in urinary porphobilinogen, a requirement for diagnosis, between 15 and 130 times the normal value was observed. Septic complications, such as pneumonia, septicemia, and urinary infection, were frequent (50%). Factors suspicious of triggering crisis episodes were: drugs, usually more than 2, in 50% of the cases; pregnancy in 30% of the women and in a lesser proportion, intense exercise, and surgery. In 10 patients, crisis triggering factors were not identified or informed. The role of pregnancy, childbirth delivery or puerperium in causing a crisis is not clear, because the patients who had a crisis related to them had 15 other pregnancies without incidents; besides, in the pregnancy which was accompanied by a crisis, there was always one or more than one potentially triggering drug present. The first therapeutic step was oral and/or parenteral administration of an overload of carbohydrates and, if there was no response, intravenous infusion of hematin was prescribed. Four (13.3%) patients died even though they had received hematin, but it had been administered too late due to a delay in diagnosis. In surviving patients, there were no organic sequels of any kind.
