RESUMO

Sodium nitrite (NaNO2) is a compound with broad practical applications in food preservation, automotive maintenance, and animal control. Sodium nitrite is also potentially fatal when ingested, as it interferes with the ability of red blood cells to transport oxygen. While incidents of accidental consumption have been reported in the literature, case reports of sodium nitrite being used as a pharmacological suicide agent are becoming more frequent. Therefore, a study was undertaken to evaluate trends in sodium nitrite deaths in South Australia between 2000 and 2019. All cases of fatal sodium nitrite ingestion were identified in the Toxicology database and autopsy reports at Forensic Science SA (FSSA). Ten cases of fatal sodium nitrite ingestion were identified, with the rate of cases increasing significantly over the study period (p > .001). Of the ten deaths attributed to sodium nitrite toxicity, eight were male, and two were female. The age range of decedents was 22-74 years (mean 51.9, SD 21.1), 22-74 years for males (mean 58.4, SD 18.2) and 23-29 years for females (mean 26.0, SD 4.2). Males (80%) and those with a history of depression and/or suicidal ideation (70%) were over-represented within the study population. While autopsy findings were generally consistent with the literature, scene findings emphasized the accessibility of sodium nitrite to the general public. This study highlights both a significant increasing trend in the use of sodium nitrite in suicides and important analytical limitations in the evaluation of suspected cases.

RESUMO

Melanoma and keratinocyte skin cancer (KSC) are the most common types of cancer in White-skinned populations. Both tumor entities showed increasing incidence rates worldwide but stable or decreasing mortality rates. Rising incidence rates of cutaneous melanoma (CM) and KSC are largely attributed to increasing exposure to ultraviolet (UV) radiation, the main causal risk factor for skin cancer.Incidence rates of KSC, comprising of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), are much higher than that of melanoma. BCC development is mainly the cause of an intensive UV exposure in childhood and adolescence, while SCC development is related to chronic, cumulative UV exposure over decades. Although mortality is relatively low, KSC is an increasing problem for health care services causing significant morbidity.Cutaneous melanoma is rapidly increasing in White populations, with an estimated annual increase of around 3-7% over the past decades. In contrast to SCC, melanoma risk is associated with intermittent and chronic exposure to sunlight. The frequency of its occurrence is closely associated with the constitutive color of the skin and the geographical zone. Changes in outdoor activities and exposure to sunlight during the past 70 years are an important factor for the increasing incidence of melanoma. Mortality rates of melanoma show stabilization in the USA, Australia, and in European countries. In the USA even dropping numbers of death cases were recently reported, probably reflecting efficacy of the new systemic treatments.Among younger cohorts in some populations (e.g., Australia and New Zealand,), stabilizing or declining incidence rates of CM are observed, potentially caused by primary prevention campaigns aimed at reducing UV exposure. In contrast, incidence rates of CM are still rising in most European countries and in the USA. Ongoing trends towards thinner melanoma are largely ascribed to earlier detection.

RESUMO

Despite the steady decline in the incidence of colorectal cancer (CRC) and cancer-related mortality in Americans of 50 years and older over the last few decades, there has been a disturbing trend of steadily rising incidence in early-onset colorectal cancer (EOCRC), defined as CRC in those younger than 50 years. With the incidence of EOCRC increasing from 4.8 per 100,000 in 1988 to 8.0 per 100,000 in 2015, and with the decreased rates in those older than 50 years largely attributed to improved screening in the older population, new screening recommendations have recently lowered the age for screening average-risk individuals from 50 to 45. EOCRC has been found to present differently from late-onset CRC, with a higher proportion of patients presenting with left-sided and rectal cancer, more aggressive histological features, and more advanced stage at the time of diagnosis. This article reviews the most recent evidence from population-based studies and institutional series, as well as the newest screening guidelines, and provides an up-to-date summary of our current understanding of EOCRC, from clinical presentation to tumor biology and prognosis, and future directions in treatment and prevention.

RESUMO

Objective:  Endometrial cancer diagnosis in younger women is increasing in Puerto Rico and the United States. The study aims to evaluate the endometrial cancer trends in incidence, mortality, and survival by comparing US ethnic groups (NHW, NHB, and Hispanic) to women living in PR to assess whether disparities exist by age and stage at diagnosis on outcomes of interest. Methods:  We performed a secondary data analysis and comparison of the age-specific and age-adjusted incidence rates, mortality rates, and the survival of endometrial cancer in PR with that of NHB, NHW, and Hispanic using data from the PR Central Cancer Registry, the SEER Program, and PR Demographic Registry from 2000 to 2018. Results:  PR had the highest incidence rates (41.3 per 100,000 women) of endometrial cancer, followed by NHW, NHB, and Hispanic. Women in PR younger than 65 years old had higher incidence rates of endometrial cancer than compared groups. NHB have higher overall mortality rates (12.5 per 100,000 women). Between ages 20-34 and 35-49, women in PR have the highest mortality rates, and after age 50, mortality rates are higher for NHB. Conclusions: Women in PR had higher endometrial cancer incidence rates in increasing trend from 2000 to 2018 compared to similar NHB, Hispanic, and NHW cohorts. Also, women in PR experienced higher incidence and mortality rates below 50 years old among all races and ethnicities. Future studies are needed to evaluate histology, obesity trends, and the impact on the quality of life for this cohort.

RESUMO

OBJECTIVE: In 2018, colorectal cancer (CRC) was the second most frequent malignancy in Romania after lung cancer. Although CRC is typically encountered in patients >50 years old, CRC's global incidence among younger adults has been increasing. We aimed to compare the disease characteristics of patients with CRC aged ≤50 years with those >50 years old. METHODS: We retrospectively evaluated data from patients with CRC who underwent standard surgery at "Pius Brinzeu" Emergency County Hospital, Timisoara, Romania. Patients were divided into two groups: Group 1 (patients ≤50 years old) and Group 2 (patients >50 years old). Six parameters were analyzed (sex, residence location, age, tumor localization, microscopic findings, pathological staging). RESULTS: Data on age-related CRC were available for 1380 patients treated from January 2012 to December 2018. Group 1 included 120 patients while group 2 included 1260 patients. Significantly more Group 1 patients presented with advanced CRC compared with Group 2 patients (94.2% vs. 87.4%). Furthermore, CRC in younger adults was more likely to be diagnosed at an advanced stage. CONCLUSIONS: Monitoring the CRC incidence in younger adults is essential to assess whether screening practices require changes and to raise awareness among clinicians of the increasing CRC incidence among younger patients.
