RESUMO

The case history and toxicological findings of a fatal PineSol intoxication are presented. An 89-year-old white female with Alzheimer's disease accidentally drank PineSol and was subsequently brought to the hospital where she was pronounced dead on arrival. Significant autopsy findings included acute erosive gastritis. There appeared to be no aspiration of PineSol into the lungs. Isopropanol along with 1-alpha-terpineol are the two major toxic ingredients of PineSol. The toxicological screening and quantitiation of 1-alpha-terpineol in postmortem fluids was performed by gas chromatography-mass spectrometry using a simple one-step extraction. Postmortem blood, urine, and gastric levels of 1-alpha-terpineol were 11.2 mg/L, 5.76 mg/L, and 15.3 g/L, respectively. Postmortem blood, vitreous humor, urine, and gastric acetone concentrations were 25, 31, 33, and 28 mg/dL. Postmortem concentrations of isopropanol were less than 10 mg/dL in the blood, vitreous humor, urine, and gastric contents. The cause of death was ruled acute 1-alpha-terpineol intoxication due to accidental ingestion of PineSol, presumably caused by confusion related to Alzheimer's disease.

RESUMO

A 45-year-old male veterinarian was found dead in bed. Police investigation showed no evidence of trauma or other suspicious circumstances. Autopsy was unremarkable except for cardiomegaly and hepatosplenomegaly. Toxicological analysis revealed the presence of Telazol and ketamine. Telazol is a veterinary anesthetic agent that is composed of equal parts of tiletamine and zolazepam. Tiletamine is a disassociative anesthetic similar to ketamine and phencyclidine, and zolazepam is a diazepine derivative tranquilizer used to minimize the muscle hypertonicity and seizures associated with tiletamine. Quantitation of tiletamine and zolazepam was performed using gas chromatography-mass spectrometry in the selected ion monitoring mode following a solid-phase extraction. Postmortem blood, urine, and liver concentrations of tiletamine were 295 ng/mL, 682 ng/mL, and 196 ng/g, respectively, whereas postmortem concentrations of zolazepam for the same tissues were 1.71 microg/mL, 1.33 microg/mL, and 15.5 microg/g, respectively. Blood and urine ketamine levels were 37 ng/mL and 381 ng/mL, respectively. The cause of death was ruled an acute mixed drug intoxication of tiletamine, zolazepam, and ketamine with the manner of death ruled as unclassified.

RESUMO

STUDY OBJECTIVE: Aerosolized ipratropium bromide or orally administered baclofen or oxybutynin chloride (Ditropan) block methacholine-associated airway hyperreactivity in subjects with chronic cervical spinal cord injury (SCI), whereas these agents do not inhibit airway hyperreactivity associated with the inhalation of histamine. The present study was performed to determine whether pretreatment with a beta2-agonist attenuates airway hyperresponsiveness in these subjects. PARTICIPANTS: Subjects with chronic cervical SCI previously demonstrating airway hyperreactivity were challenged with methacholine (n = 9) or histamine (n = 16) alone and, on a separate day, 25 min following inhalation of nebulized metaproterenol sulfate. RESULTS: Inhalation of the beta2-agonist was associated with an increase in provocative concentration causing a 20% decrease in FEV1 (PC20) values (geometric mean) from 1.01+/-2.76 to 20.54+/-6.24 mg/mL for methacholine and from 2.29+/-2.26 to 19.82+/-5.93 mg/mL for histamine. No correlation was found between specific PC20 values for individual subjects and percentage improvement in FEV1 (liter) following inhalation of metaproterenol sulfate and between PC20 values and baseline FEV1 percent. CONCLUSION: These data, combined with findings that patients with chronic high cervical SCI experience increased breathlessness following exposure to exogenous agents, suggest that long-term prophylactic beta2-agonist therapy may reduce respiratory symptoms associated with airway hyperreactivity in these patients.

RESUMO

Bronchial provocation studies performed in our research center have consistently demonstrated airway hyperresponsiveness to both inhaled methacholine and histamine in subjects with chronic cervical spinal cord injury (SCI). More recently, we reported that the airways of such subjects maintained on chronic baclofen (gamma-aminobutyric acid) therapy were not hyperreactive to inhaled methacholine. In this study we determined whether baclofen also blocks the effects of the bronchoprovocative agent histamine in subjects with cervical SCI. Twenty-four male subjects with cervical SCI participated in this study; 14 were maintained on oral baclofen, and 10 served as age-matched controls. The subjects were challenged with increasing concentrations of aerosolized histamine until either a 20% fall in forced expiratory volume in 1 s (FEV1) from baseline (defined as PC20) was observed, or a maximum of 25 mg/ml histamine was administered. We found that 11 of the 14 baclofen subjects (78.5%) and 8 of the 10 control subjects (80%) responded (PC20 < 8 mg/ml) to the histamine challenge. Mean PC20 values among responders in the baclofen (PC20 = 2.91 +/- 2.3) and control (PC20 = 2.18 +/- 1.9) groups did not differ significantly. Because histamine acts directly on histamine receptors and indirectly on cholinergic pathways, our findings that baclofen blocks bronchoconstriction due to inhaled methacholine, but not that due to histamine, suggests that hyperresponsiveness in subjects with cervical SCI may be secondary to nonspecific airway hyperreactivity.

RESUMO

Based on cognitive dissonance and related theories of commitment, this study tested hypotheses that planning pregnancy and number of months spent trying to conceive would be associated with better prenatal health behaviors and that commitment to pregnancy and motherhood would mediate these associations. Participants (N = 96) were pregnant women at high medical risk for an adverse birth outcome. As predicted, planning pregnancy predicted better prenatal health care practices, and this effect was mediated by commitment level. Among women who planned their pregnancy, longer time to conceive predicted higher commitment but did not influence prenatal health behaviors directly. Women who had given birth previously practiced fewer prenatal health behaviors. Commitment, however, remained the strongest predictor of prenatal health care practices. Results are consistent with theories of commitment and with prominent approaches to the study of health behavior.

RESUMO

BACKGROUND: Topical preparations are sometimes applied before phototherapy without consideration of their potential to block UVB. OBJECTIVE: Our purpose was to examine the ability of topical preparations to block UVB. METHODS: Volunteers pretreated with mineral oil, a clear liquid emollient, 5% crude coal tar, 6% salicylic acid ointment, emollient creams, and petrolatum underwent minimal erythema dose testing. Transmission of UVB through a clear film coated with the preparations was measured. RESULTS: Tars and salicylic acid blocked UVB. Thick application of petrolatum and emollient creams can reduce transmission of UVB. Mineral oil and a clear liquid emollient did not significantly affect transmission or erythemogenicity of UVB. CONCLUSION: Clear liquid emollient and mineral oil can be used before phototherapy. If not removed before phototherapy, preparations containing tar or salicylic acid, or thickly applied petrolatum or emollients, can block UVB and presumably reduce its efficacy in the treatment of psoriasis.

RESUMO

A case of esophageal perforation occurring in a 75-year-old man is presented. The clinical presentation was benign and the diagnosis of esophageal perforation was made incidental to an upper gastrointestinal barium examination. Conservative management consisting of nasogastric suctioning, antibiotics and antacids was effective in minimizing the clinical course. This represents a rare instance of a successful nonsurgical approach to esophageal perforation.

RESUMO

A case report and review of the literature of benign gastric ulcer complicated by gastrocolic fistula are presented. Twenty-seven percent of patients were found to be receiving ulcerogenic medications. Only 15% of patients had previous histories of ulcer disease. Parameters most suggestive of a neoplastic process included palpable abdominal mass and unexplained anemia. Diagnosis is established by barium enema. Endoscopic biopsy and cytologic studies are useful in differentiating benign from malignant processes. Surgical management of benign ulcers complicated by fistula results in more than 90% survival.

RESUMO

A 51-year-old man with clinical and laboratory findings consistent with the diagnosis of pancreatic ascites is reported. Response to usual medical measures was inadequate. Single-dose irradiation to the pancreatic area (550 rads) resulted in marked improvement in his ascites. Operative pancreatogram months later revealed no evidence of ductal leakage. Low-dose pancreatic irradiation may be a unseful therapeutic adjunct in the older, high-risk patient with pancreatic ascites in whom surgery is not considered feasible.
