RESUMO
Nandina domestica is grown as an ornamental plant in the United States but has also been reported as an invasive plant in a number of states. Parts of the plant, particularly the berries, contain cyanogenic glycosides that convert to hydrogen cyanide when ingested. This investigation characterized N. domestica ingestions involving patients of age 5 years and less reported to Texas poison centers during 2000-2015. There were 875 total N. domestica ingestions. A seasonal pattern was observed with the highest proportion of ingestions occurring in March (18.5%) and April (14.7%). The patients were male in 55.0% of the cases; 40.8% of the patients were of age 1 and 37.0% of age 2. Berries were specifically mentioned in 709 ingestions, of which 57.3% involved one berry and 28.5% an unknown number of berries. The ingestion occurred at the patient's own residence in 92.9% of the cases, and the patient was managed on site in 97.0%. The most frequently reported clinical effects were vomiting (3.7%), abdominal pain (1.0%), diarrhea (0.9%), and nausea (0.7%). In conclusion, N. domestica ingestions among young children generally do not result in serious outcomes and can be managed successfully outside of a healthcare facility.

OBJECTIVES: There is little information on poisonings managed at military and Veterans Administration (VA) hospitals. This investigation described and compared poisonings reported to Texas poison centers that were managed at military and VA hospitals. STUDY DESIGN: Retrospective analysis of poison centre data. METHODS: Cases were poisonings among patients aged 18 years or more reported to Texas poison centers during 2000-2015 where management occurred at a military or VA hospital. The distribution of exposures for various demographic and clinical factors was determined for military and veterans hospitals and comparisons were made between the two groups. RESULTS: There were 4353 and 1676 poisonings managed at military and VA hospitals, resepctively. Males accounted for 50.5% of the military hospital patients and 84.9% of the VA hospital patients. The mean age for military hospital patients was 31 years and for VA hospital patients was 50 years. The proportion of poisonings managed at military hospitals and VA hospitals, respectively, were intentional (70.0% vs 64.1%), particularly suspected attempted suicide (57.3% vs 47.7%), and unintentional (25.0% vs 30.5%). More than one substance was reported in 37.7% of military and 33.2% of VA hospital poisonings. The most commonly reported substance categories for poisonings managed at military and VA hospitals, respectively, were analgesics (28.4% vs 19.7%), sedatives/hypnotics/antipsychotics (24.7% vs 23.4%), antidepressants (18.7% vs 19.7%) and alcohol (11.3% vs 10.6%). CONCLUSIONS: A number of differences were observed between poisonings managed at military and VA hospitals. These differing patterns of poisonings may need to be taken into account in the education, prevention and treatment of poisonings at these hospitals and among the populations they serve.

A combination of pentobarbital and phenytoin is used as a veterinary euthanasia drug. Because of its lethal effect, this study described pentobarbital-phenytoin combination veterinary drug human exposures reported to Texas poison centers during 2000-2015. Of 66 exposures, 73% involved female and 27% male patients. The distribution by patient age was 3% 0-5 years, 5% 6-19 years, 91% 20+ years, and 2% unknown. The most common routes were ocular (41%), ingestion (32%), injection (23%), and dermal (18%). The exposure reasons were unintentional (77%) and intentional (23%). The exposure site was the workplace (52%), patient's own residence (38%), health-care facility (2%), and other/unknown (9%). The management site was managed on site (48%), at/en route to health-care facility (45%), referred to health-care facility (5%), and other (2%). The medical outcomes were no effect (23%), minor effect (30%), moderate effect (8%), major effect (8%), not followed nontoxic (3%), not followed minimal effects (24%), unable to follow potentially toxic (2%), and unrelated (3%). The most common adverse effects were ocular irritation/pain (18%), drowsiness/lethargy (15%), and coma (9%). The most common treatments were dilution/irrigation (70%), intravenous fluids (21%), and oxygen (14%). This study found few pentobarbital-phenytoin combination veterinary drug exposures were reported to Texas poison centers during a 16-year period. Although meant to be administered intravenously, the most common exposure routes were ocular and ingestion. Many of the exposures appeared to be unintentional and occurred at the workplace.

Poison centers advance knowledge in the field of toxicology through publication in peer-review journals. This investigation describes the pattern of poison center-related publications. Cases were poison center-related research published in peer-review journals during 1995-2014. These were identified through searching the PubMed database, reviewing the tables of contents of selected toxicology journals, and reviewing abstracts of various national and international meetings. The following variables for each publication were identified: year of publication, journal, type of publication (meeting abstract vs. other, i.e. full article or letter to the editor), and the country(ies) of the poison center(s) included in the research. Of the 3147 total publications, 62.1% were meeting abstracts. There were 263 publications in 1995-1999, 536 in 2000-2004, 999 in 2005-2009, and 1349 in 2010-2014. The publications were in 234 different journals. The journals in which the highest number of research was published were Clinical Toxicology (69.7%), Journal of Medical Toxicology (2.2%), and Veterinary and Human Toxicology (2.1%). The research was reported from 62 different countries. The countries with the highest number of publications were the United States (67.9%), United Kingdom (6.5%), Germany (3.9%), France (2.5%), and Italy (2.4%). The number of publications increased greatly over the 20 years. Although the publications were in a large number of journals, a high proportion of the publications were in one journal. While the research came from a large number of countries, the preponderance came from the United States.

Neonicotinoids are a relatively newer class of insecticide. Used primarily in agriculture, neonicotinoids are also used for flea control in domestic animals. Information on human exposures to neonicotinoids is limited. Neonicotinoid exposures reported to Texas poison centers during 2000-2012 were identified and the distribution by selected factors examined. Of 1,142 total exposures, most products contained imidacloprid (77%) or dinotefuran (17%). The exposures were seasonal with half reported during May-August. The most common routes of exposure were ingestion (51%), dermal (44%), and ocular (11%). The distribution by patient age was 5 years or less (28%), 6-19 years (9%), 20 years or more (61%), and unknown (2%); and 64% of the patients were female. Of all, 97% of the exposures were unintentional and 97% occurred at the patient's own residence. The management site was on-site (92%), already at/en route to a health care facility (6%), and referred to a health care facility (2%). The medical outcomes included no effect (22%), minor effect (11%), moderate effect (1%), not followed judged nontoxic (14%), not followed minimal effects (46%), unable to follow potentially toxic (1%), and unrelated effect (4%). The most commonly reported adverse clinical effects were ocular irritation (6%), dermal irritation (5%), nausea (3%), vomiting (2%), oral irritation (2%), erythema (2%), and red eye (2%). The most frequently reported treatments were dilution/wash (85%) and food (6%). In summary, these data suggest that the majority of neonicotinoid exposures reported to the poison centers may be managed outside of health care facilities with few clinical effects expected.

Synthetic cannabinoids have recently gained popularity as a recreational drug because they are believed to result in a marijuana-like high. This investigation compared synthetic cannabinoids and marijuana exposures reported to a large statewide poison center system. Synthetic cannabinoid and marijuana exposures reported to Texas poison centers during 2010 were identified. The distribution of exposures to the two agents with respect to various demographic and clinical factors were compared by calculating the rate ratio (RR) of the synthetic cannabinoid and marijuana percentages for each subgroup and 95% confidence interval (CI). The proportion of synthetic cannabinoid and marijuana exposures, respectively, were 87.3% and 46.5% via inhalation (RR 1.88, 95% CI 1.38-2.61), 74.9% and 65.7% in male (RR 1.14, 95% CI 0.87-1.51), 40.2% and 56.6% age ≤ 19 years (RR 0.71, 95% CI 0.52-0.98), 79.2% and 58.6% occurring at a residence (RR 1.35, 95% CI 1.02-1.82), 8.4% and 16.2% managed on-site (RR 0.52. 95% CI 0.28-1.00), and 59.3% and 41.4% with serious medical outcomes (RR 1.43, 95% CI 1.03-2.05). Compared to marijuana, synthetic cannabinoid exposures were more likely to be used through inhalation, to involve adults, to be used at a residence, and to result in serious outcomes.

Little data exist regarding pediatric celecoxib ingestions. This study described the pattern of pediatric celecoxib ingestions reported to poison control centers. Cases were isolated celecoxib ingestions by patients aged 0-5 years during 2000-2007 reported to Texas poison control centers. The distribution of cases was described with respect to demographic and clinical factors. Of the 177 total patients, dose ingested in milligrams was reported for 92 patients. Mean reported dose was 305.5 mg (range 10-2300 mg). Of those 92 cases, distribution by management site was 89.1% on site, 6.5% already at/en route to healthcare facility and 4.3% referred to healthcare facility. Final medical outcome was no effect for 95.7% cases and minor effect for 4.3% cases. Specific clinical effects reported (in only one case each) were rash, abdominal pain, vomiting, agitation/irritability, and drowsiness. All of the pediatric celecoxib ingestions reported to Texas poison control centers resulted in no or minor effect.

Metformin is an oral hypoglycemic agent used in the management of type 2 diabetes mellitus. Limited information exists on adult metformin ingestions reported to poison control centers. The distribution of adult metformin ingestions reported to Texas poison control centers during 2000-2006 was determined for various factors. In addition, triage guidelines for the management of isolated ingestions were drafted. Of 1528 total metformin ingestions, 58% involved coingestants. Of the 264 ingestions of metformin alone, where the final medical outcome was known, dose ingested was reported for 66%. The mean reported dose was 4739 mg (range 500-60,000 mg). Ingestions of < or =2500 mg and >5000 mg reported doses differed with respect to the proportion involving suspected attempted suicide (6% versus 81%), serious final medical outcome (3% versus 19%), and referral to a health care facility (3% versus 83%). Using 5000 mg as a threshold dose for referral to a health care facility, 91% of cases not already at or en route to a health care facility were managed according drafted triage guidelines.

OBJECTIVES: Since January 2002, the US Food and Drug Administration (FDA) has issued a number of advisories about the use of antidepressants, including selective serotonin re-uptake inhibitors (SSRIs). These advisories may have influenced the number of SSRI exposures reported to poison control centres. The purpose of this study was to examine time trends in SSRI exposures reported to poison control centres in Texas with respect to the timing of the various advisories. STUDY DESIGN: Retrospective review of data from poison control centres. METHODS: Cases were divided into two groups: (1) paroxetine exposures and (2) other SSRI exposures reported to poison control centres in Texas between 1998 and 2006. The month and year of the call, and patient age and gender were identified. The mean monthly number of ingestions for the two groups was calculated for six time periods related to the FDA advisories. RESULTS: The mean monthly number of total paroxetine ingestions between January 2002 and June 2003 was 77.6. This declined by 23.3% to 59.6 in July 2003-March 2004 after an advisory about the risk of suicidality in youths using paroxetine. Comparable mean monthly numbers for patients aged <20 years were 33.3 and 20.3, respectively (decline of 38.9%); and for patients aged >or=20 years were 44.0 and 38.6, respectively (decline of 12.4%). Mean monthly numbers for total other SSRI ingestions were 206.4 and 243.1, respectively (increase of 17.8%). CONCLUSIONS: The FDA advisory in June 2003 appeared to initiate a decline in paroxetine ingestions, particularly among patients aged <20 years, but did not appear to influence other SSRI ingestions reported to poison control centres in Texas.

Limited information exists on potentially adverse adult glyburide ingestions reported to poison control centers. Using adult glyburide ingestions reported to Texas poison control centers during 1998-2005, the proportion of cases involving serious outcomes was determined for selected variables and evaluated for statistical significance by calculating the rate ratio (RR) and 95% confidence interval (CI). Of 126 cases identified, 49 (39%) involved serious outcomes. Serious outcomes were significantly more likely to occur with a maximum dose>24 mg (RR 4.74, 95% CI 1.74-14.90) or >4 tablets (RR 3.27, CI 1.57-7.31), where the circumstances of the exposures involved self-harm or malicious intent (RR 2.44, CI 1.33-4.46), or the patient was already at or en route to a health care facility when the poison control center was contacted (RR 12.89, CI 4.00-66.12) or referred to a health care facility by the poison control center (RR 12.21, CI 3.53-65.01). The severity of the outcome associated with adult glyburide ingestions depended on the dose and the circumstances of the ingestion. The management of patients with severe outcomes was more likely to involve health care facilities. Such information is useful for creating triage guidelines for the management of adult glyburide ingestions.

Limited information exists on potentially adverse escitalopram ingestions reported to poison control centers. Using isolated escitalopram ingestions reported to Texas poison control centers during 2002-2005, the proportion of cases involving serious medical outcomes was determined for selected variables and evaluated for statistical significance by calculating the rate ratio (RR) and 95% confidence interval (CI). Of 1179 cases identified, 234 (20%) involved serious outcomes. Serious outcomes were significantly more likely to occur with a maximum dose of >100 mg (RR 4.69, CI 2.52-9.29) or >5 tablets (RR 4.96, CI 2.94-8.93), where the circumstances of the exposures involved self-harm or malicious intent (RR 3.21, CI 2.42-4.29), or when the patient was already at or en route to a health care facility when the poison control center was contacted (RR 7.88, CI 4.31-15.79) or referred to a health care facility by the poison control center (RR 15.91, CI 8.78-31.64). The severity of the outcome associated with isolated escitalopram ingestions depended on the dose and the circumstances of the ingestion. The management of patients with serious outcomes were more likely to involve health care facilities. Such information is useful for creating triage guidelines for the management of escitalopram ingestions.

Lisinopril is not recommended for use by young children. This study attempted to identify factors associated with serious outcomes in pediatric lisinopril ingestions. Cases for this study were lisinopril ingestions by children age < or =5 years reported to Texas poison control centers during 1998-2005. The percentage of cases involving serious medical outcomes was identified for selected variables and evaluated for statistical significance by calculating the rate ratio (RR) and 95% confidence interval (CI). Of 691 total cases, 26 (3.8%) involved a serious outcome. Higher serious outcome rates were found with a maximum dose of >4 mg/kg (RR: 2.54, CI: 0.05-25.62), or >80 mg (RR: 7.85; CI: 1.73-29.29), or five or more tablets (RR: 8.18; CI: 2.73-22.54), or the patient was already at or en route to a health care facility when the poison control center was contacted (RR: 13.93; CI: 3.68-77.78), or referred to a health care facility by the poison control center (RR: 33.49; CI: 9.04-194.94). The management of patients with severe outcomes was more likely to involve health care facilities. This information is useful for drafting triage guidelines for the management of pediatric lisinopril ingestions.

Concerns have been raised about the safety of celecoxib. This study described the pattern of exposures involving only celecoxib (isolated exposures) reported to Texas poison control centers from 1999 to 2004. The mean dose was 701 mg. The patient age distribution was < or = 5 years (48%), 6-19 years (8%), and > or = 20 years (44%). In 78% of cases, exposure was unintentional. Of the exposures, 74% were managed outside of health care facilities. The final medical outcome was classified as no effect for 82% of the cases, and minor effects for 12% of the cases. Adverse clinical effects were listed for 5% of the patients, the most frequently reported being rash (3%), drowsiness (3%), pruritus (2%), and vomiting (2%). The most frequently listed treatment was decontamination by dilution (43%) or food (32%). The majority of isolated celecoxib exposures could be managed outside of health care facilities, and the outcome was generally favorable.

This study examined the relationship between selected factors and all human exposures involving jellyfish stings reported to Texas poison centers. Cases were obtained retrospectively from calls to poison centers in Texas and included all reported human exposures during 1998-2004 involving jellyfish stings. The distribution of cases was determined for a variety of demographic and clinical parameters. There were 423 total cases. Among the cases with a known patient age, 19.8% were <6 years of age, 53.5% were age 6-19 years, and 26.7% were >19 years of age. Males accounted for 52% of the cases. Of the 118 cases with a known clinical outcome, 0.8% had no effect, 80.5% had minor effects, and 18.6% had moderate effects. Counties along the Gulf Coast accounted for 72.3% of the calls. This information can be used to identify those portions of the population most at need of education regarding the prevention and treatment of jellyfish stings.

Folic acid (folacin, pteroylglutamic acid) is a monoglutamate form of the water-soluble B vitamin that is involved in the synthesis of nucleotides and amino acids and the normal maturation of red blood cells. This study describes the folic acid calls received by Texas poison centers during 1998-2003. There were 650 calls involving folic acid as a single-ingredient product, of which 55.1% were human exposures. Children age <6 years accounted for 80.1% of the human exposures. Patients were managed outside of the health care facilities in 92.1% of the cases. Of those cases with a known medical outcome, 94.8% had no clinical effects. This study found folic acid exposures reported to poison centers were unlikely to have more than minor adverse affects.

The most common major birth defects affecting the oesophagus and trachea are oesophageal atresia (OA) and tracheo-oesophageal fistula (TOF). Epidemiological information on OA and/or TOF in the USA has been derived from only a few populations. Sixty-one cases of OA or TOF were identified through a population-based birth defects registry in Hawaii during 1986-2000. The relationship between various clinical and demographic factors and OA or TOF were examined. The rate of OA or TOF was 2.2 per 10,000 live births. The cases were 67.2% OA with TOF, 21.3% TOF alone, and 11.5% OA alone. Risk of OA or TOF was significantly higher among multiple births and live births with low birth weight and gestational age. The risk of OA or TOF was significantly higher for whites. The rate of OA or TOF was consistent with that reported elsewhere. The risk of the defects differed significantly between the major racial/ethnic groups in Hawaii. The impact of many factors on OA or TOF in Hawaii was similar to that reported elsewhere.

Atresia and stenosis are some of the most common birth defects affecting the small intestine. Few population-based studies have examined the epidemiology of small intestinal atresia/stenosis. Eighty-two cases of small intestinal atresia/stenosis were identified through a population-based birth defects registry in Hawaii during 1986-2000. The relationships of various clinical and demographic factors with small intestinal atresia/stenosis and duodenal atresia/stenosis were examined. The small intestinal atresia/stenosis and duodenal atresia/stenosis rates were 2.9 per 10,000 live births [95% confidence interval (CI) 2.3-3.6] and 1.3 per 10,000 live births (95% CI 1.0-1.9), respectively. No secular trend was observed (P = 0.067 and 0.090, respectively). Maternal age risk for small intestinal atresia/stenosis was U-shaped, while duodenal atresia/stenosis rates were highest with maternal age of 35 years or more. Small intestinal atresia/stenosis was substantially more common among Far East Asians than Caucasians [rate ratio (RR) 1.96, 95% CI 1.24-2.94]. Duodenal atresia/stenosis risk was higher in Hawaii County than in Honolulu County (RR 2.55, 95% CI 1.10-5.02). Small intestinal atresia/stenosis was also associated with low birth weight (RR 11.50, 95% CI 8.05-15.92), low gestational age (RR 8.60, 95% CI 6.34-11.41) and multiple births (RR 3.79, 95% CI 1.39-8.24). In conclusion, this study found associations between small intestinal atresia/stenosis and maternal age, maternal race/ethnicity, county of residence, birth weight, gestational age and plurality, but not delivery period. Many of the associations between small intestinal atresia/stenosis and other factors noted in this investigation were similar to those reported by other studies.
