RESUMO
A simple and rapid method that is not based on race and ethnicity for classifying people with skin of color is of paramount importance in dermatology. The currently used Fitzpatrick classification of sun-reactive skin types is inadequate. Newer scales that have been used in immigration surveys and sociology studies are not applicable in the office setting. A new, non-racial and non-ethnic, colorimetric scale for skin of color has recently been proposed that is simple to perform. The scale has five colors: very light beige (skin color type 1), light brown (skin color type 2), medium brown (skin color type 3), dark brown (skin color type 4) and very dark brown (skin color type 5); an individual with white skin, such as in albinism, would have a skin color type 0 in this classification. In conclusion, the colorimetric scale enables the rapid classification of individuals with skin of color and allows for accurate assessment of skin cancer risk, more appropriate management of cosmetic dermatologic procedures and aesthetic devices, and enhanced ability for focused counseling regarding hair products, skin care interventions, and color-targeted makeup based on the person's skin tone.

Skin of color refers to individuals whose skin color ranges from very light beige to very dark brown. Anthropologists and sociologists have previously recognized the importance of an objective classification of skin color for individuals with skin of color that does not include race and ethnicity. Since 1975, dermatologists have used the Fitzpatrick classification of sun-reactive skin types to categorize patients with skin of color; this classification was established for psoriasis patients participating in using oral methoxsalen and phototherapy clinical trial to determine the initial ultraviolet A dose. The Fitzpatrick classification merely classifies individuals as white, brown, and black; the individuals with white skin are further divided into four groups based on their burning or tanning capacity. This classification system does not provide reliable information with regard to the risk of skin cancer for individuals with darker skin color and does not aid in the evaluation of medical conditions with cutaneous involvement or assessment of appropriate cosmetic interventions for aesthetic management. Many clinicians, including forensic pathologists, incorporate the patient's race or ethnicity in their medical evaluation to describe the individual's skin color. Established scales for skin of color either include white skin color, or include 10 or more color types, or include both. We introduce a simple and rapidly performed scale that is not based on race or ethnicity to categorize persons with skin of color. The colorimetric scale ranges from very light beige to very dark brown and does not include white skin. The scale has five colors ranging from lightest (skin color type 1) to darkest (skin color type 5): very light beige (skin color type 1), light brown (skin color type 2), medium brown (skin color type 3), dark brown (skin color type 4), and very dark brown (skin color type 5); an individual with white skin would have a skin color type 0 in this classification of patient skin color. In conclusion, a scale that is not based on race or ethnicity is useful for categorizing individuals with skin of color not only for sociologists but also for clinicians who treat these patients. This colorimetric scale will be helpful for dermatologists to categorize persons with skin of color to predict their risk for developing skin cancer and to assessing appropriate cosmetic procedures and devices for these patients. In addition, the colorimetric scale will be useful for not only forensic pathologists but also other clinicians to provide a non-racial and non-ethnic designation of skin color type for their patients.
RESUMO
The pathogenesis of multi-organ dysfunction associated with severe acute SARS-CoV-2 infection remains poorly understood. Endothelial damage and microvascular thrombosis have been identified as drivers of COVID-19 severity, yet the mechanisms underlying these processes remain elusive. Here we show alterations in fluid shear stress-responsive pathways in critically ill COVID-19 adults as compared to non-COVID critically ill adults using a multiomics approach. Mechanistic in-vitro studies, using microvasculature-on-chip devices, reveal that plasma from critically ill COVID-19 adults induces fibrinogen-dependent red blood cell aggregation that mechanically damages the microvascular glycocalyx. This mechanism appears unique to COVID-19, as plasma from non-COVID sepsis patients demonstrates greater red blood cell membrane stiffness but induces less significant alterations in overall blood rheology. Multiomics analyses in pediatric patients with acute COVID-19 or the post-infectious multi-inflammatory syndrome in children (MIS-C) demonstrate little overlap in plasma cytokine and metabolite changes compared to adult COVID-19 patients. Instead, pediatric acute COVID-19 and MIS-C patients show alterations strongly associated with cytokine upregulation. These findings link high fibrinogen and red blood cell aggregation with endotheliopathy in adult COVID-19 patients and highlight differences in the key mediators of pathogenesis between adult and pediatric populations.

Melioidosis, caused by the bacterium Burkholderia pseudomallei, is an uncommon infection that is typically associated with exposure to soil and water in tropical and subtropical environments. It is rarely diagnosed in the continental United States. Patients with melioidosis in the United States commonly report travel to regions where melioidosis is endemic. We report a cluster of four non-travel-associated cases of melioidosis in Georgia, Kansas, Minnesota, and Texas. These cases were caused by the same strain of B. pseudomallei that was linked to an aromatherapy spray product imported from a melioidosis-endemic area.

OBJECTIVES: We describe the experience of a busy metropolitan medical examiner's office in the United States and share our navigation of the COVID-19 autopsy decision-making process. We describe key gross and microscopic findings that, with appropriate laboratory testing, should direct a pathologist towards a COVID-19-related cause of death. MATERIAL AND METHODS: We performed a retrospective review of 258 suspected and/or confirmed COVID-19 associated deaths that occurred between March 5, 2020, and March 4, 2021. RESULTS: A total of 62 cases due to fatal COVID-19 were identified; autopsy findings included diffuse alveolar damage, acute bronchopneumonia and lobar pneumonia, and pulmonary thromboemboli. Nine additional decedents had a nasopharyngeal swab positive for SARS-CoV-2 and a cause of death unrelated to COVID-19. Forty-seven cases with COVID-19-like symptoms showed no laboratory or histopathologic evidence of SARS-CoV-2 infection; the most common causes of death in this group were hypertensive or atherosclerotic cardiovascular disease, complications of chronic alcoholism, and pulmonary thromboemboli unrelated to infection. CONCLUSIONS: The clinical findings associated with COVID-19 are not specific; a broad differential diagnosis should be embraced when decedents present with cough or shortness of breath. An autopsy may be indicated to identify a cause of death unrelated to COVID-19.

Few cases of natural sudden death presenting as an undiagnosed lymphoma have been reported in the literature, especially in adolescents. Herein we provide a report of sudden death caused by undiagnosed classic Hodgkin lymphoma (cHL). We describe an 18-year-old female who collapsed after several weeks of weight loss, decreased appetite, and dyspnea. At autopsy, a bulky mass arising in the mediastinum and neck compressed the esophagus and trachea, surrounded the great vessels, obliterated the pericardial sac, and infiltrated the myocardium. The lungs were collapsed and large pleural effusions were present. The tumor burden, which weighed at least 2710 g in aggregate, was entirely above the diaphragm. Microscopic examination of the masses showed features typical for nodular sclerosis cHL including large bands of sclerosis, numerous Hodgkin/Reed-Sternberg (HRS) cells, and an eosinophil-rich mixed inflammatory cell infiltrate. Immunohistochemical stains showed the HRS cells to be uniformly positive for CD30 and CD15 and negative for CD3, CD20, CD45, and PAX5. This case exemplifies a rare sudden natural death due to previously undiagnosed cHL in a young patient.

OBJECTIVE: The aim of this study was to determine which initial surgical treatment results in the lowest rate of death or neurodevelopmental impairment (NDI) in premature infants with necrotizing enterocolitis (NEC) or isolated intestinal perforation (IP). SUMMARY BACKGROUND DATA: The impact of initial laparotomy versus peritoneal drainage for NEC or IP on the rate of death or NDI in extremely low birth weight infants is unknown. METHODS: We conducted the largest feasible randomized trial in 20 US centers, comparing initial laparotomy versus peritoneal drainage. The primary outcome was a composite of death or NDI at 18 to 22âmonths corrected age, analyzed using prespecified frequentist and Bayesian approaches. RESULTS: Of 992 eligible infants, 310 were randomized and 96% had primary outcome assessed. Death or NDI occurred in 69% of infants in the laparotomy group versus 70% with drainage [adjusted relative risk (aRR) 1.0; 95% confidence interval (CI): 0.87-1.14]. A preplanned analysis identified an interaction between preoperative diagnosis and treatment group (P = 0.03). With a preoperative diagnosis of NEC, death or NDI occurred in 69% after laparotomy versus 85% with drainage (aRR 0.81; 95% CI: 0.64-1.04). The Bayesian posterior probability that laparotomy was beneficial (risk difference <0) for a preoperative diagnosis of NEC was 97%. For preoperative diagnosis of IP, death or NDI occurred in 69% after laparotomy versus 63% with drainage (aRR, 1.11; 95% CI: 0.95-1.31); Bayesian probability of benefit with laparotomy = 18%. CONCLUSIONS: There was no overall difference in death or NDI rates at 18 to 22âmonths corrected age between initial laparotomy versus drainage. However, the preoperative diagnosis of NEC or IP modified the impact of initial treatment.

OBJECTIVE: We aimed to evaluate the sensitivity of fine needle aspiration (FNA) for the diagnosis of Hodgkin's lymphoma (HL) in HIV-infected patients. STUDY DESIGN: An electronic search was conducted to retrospectively identify patients diagnosed with HL who underwent FNA followed by confirmatory biopsy. FNAs were categorized as negative, atypical/suspicious/positive, or nondiagnostic. Diagnostic sensitivity in HIV+ and HIV- patients was statistically compared via Fisher's exact test, with a p value <0.05 considered significant. RESULTS: Thirty-six patients meeting inclusion criteria were identified (24 HIV- and 12 HIV+). Average age was 36.0 ± 11.5 and 36.5 ± 7.4 years (means ± SD) in HIV- and HIV+ patients, respectively. The male-to-female ratio was 1.4:1 in HIV- patients versus 3:1 in HIV+ patients. Among these 36 patients, a total of 42 FNAs were performed. Overall sensitivity of FNA was 66.7% (95% confidence interval: 52.4-80.9%). When stratified by HIV status, a statistically significant difference in FNA sensitivity was detected, as sen-sitivity was 84.6% (70.8-98.4%) in HIV- patients versus only 37.5% (13.8-61.2%) in HIV+ patients (p =0.003). CONCLUSION: The diagnostic sensitivity of FNA biopsy was significantly attenuated in the HIV+ cohort. In HIV-infected patients presenting with lymphadenopathy, increased clinical suspicion of HL is critical to avoid misdiagnosis.

OBJECTIVE: To evaluate the test-retest reliability of repeated in-bore MRI-guided prostate biopsy (MRGB). METHODS: 19 lesions in 7 patients who had consecutive MRGBs were retrospectively analysed. Five patients had 2 consecutive MRGBs and two patients had 3 consecutive MRGBs. Both multiparametric MRI and MRGBs were performed using a 3T MRI scanner. Pathology results were categorized into benign, suspicious and malignant. Consistency between first and subsequent biopsy results were analysed as well as the negative predictive value (NPV) for prostate cancer. RESULTS: 15 lesions (≈79%) had matching second biopsy and 4 (21%) had non-matching second biopsy. Lesions with both Prostate Imaging - Reporting and Data System(PIRADS) categories 1 and 4 were all benign and had matching pathology results. Lesions with non-matching results had PIRADS categories 2, 3 and 5. NPV for prostate cancer in first biopsy was 87.5%. Overall agreement was 78.9% and overall disagreement was 21.1%.κ = 0.55 denoting moderate agreement (p = 0.002). 10/19 lesions had a third biopsy session. 9/10 (90%) had matching pathology results across the three biopsy sessions and all matching lesions were benign. CONCLUSION: In-bore MRI-guided prostate biopsy may have a better reliability for repeat biopsies compared to TRUS biopsy. Final conclusion awaits a prospective analysis on a larger cohort of patients. Advances in knowledge: This pilot study showed that repeated prostate in-bore MRI-guided prostate biopsy may have better reliability compared to TRUS biopsy with a suggested high NPV.

BACKGROUND: This study describes the cytologic features of 26 angiosarcomas diagnosed on fine-needle aspiration. METHODS: Twenty-six angiosarcomas from 20 patients were confirmed by cytomorphology and immunocytochemical (immunohistochemistry) positivity for at least 2 of 3 vascular markers. Specimens were examined for spindled/epithelioid/plasmacytoid single cells, 3-dimensional clusters, multiple prominent/bar-shaped nucleoli (5 times longer than their width), chromatin strands, abnormal mitoses, necrosis, and vasoformative features. RESULTS: Eight males and 12 females with a mean age of 52 years (range, 2-94 years) underwent aspiration of tumors in the following: soft tissue or skin/subcutis (n = 10), bone (n = 4), nodes (n = 5), lung (n = 2), liver (n = 2), heart (n = 1), parotid gland (n = 1), and pleural fluid (n = 1). An angiosarcoma diagnosis was rendered for 24 of the 26 cases (92%); 1 was diagnosed as "atypical cells, cannot exclude angiosarcoma," and another was diagnosed as a malignant vascular neoplasm. Abnormal mitoses were most frequent (85%), and they were followed by single malignant cells (81%: epithelioid [69%], spindled [62%], and plasmacytoid [19%]), 3-dimensional clusters (54%), multiple prominent (62%) or bar-shaped nucleoli (54%), and chromatin strands (31%). Vasoformative features, including hemophagocytosis (54%), cytoplasmic lumina/vacuoles (69%) containing red blood cells (54%)/neutrophils (31%), and endothelial wrapping (69%), were seen in 88%; 23% had all vasoformative features, 88% had at least 1, and 12% had none. CONCLUSIONS: Angiosarcomas show a range of cytomorphologic features that make them potentially recognizable on cytology. Although vasoformative features are highly suggestive, they are not specific for angiosarcoma and may be seen in some nonvascular neoplasms. Immunohistochemistry and a high index of suspicion are required for an accurate diagnosis. Cancer Cytopathol 2016;124:659-68. © 2016 American Cancer Society.

In contrast to the routine (non-targeted) sampling approach of transrectal ultrasound guided biopsies (TRUS-GB), targeted magnetic resonance imaging-guided biopsies (TMRI-GB) target regions of the prostate suspicious for prostate cancer (PCa), based on findings on multiparametric MRI. We sought to examine the pathologic findings identified on TMRI-GB, due to the fact that there are limited studies on this in the Pathology literature. A search was made through our Urologic Pathology files for prostate needle core biopsies that were obtained via TMRI-GB. Forty-six patients were identified. Mean patient (PT) age was 62 years (range: 50-78 years). Twenty one of 46 PTs (46%) had a history of PCa, 10/46 PTs (22%) had a history of negative TRUS-GB and rising PSA, and the remaining 15/46 PTs (32%) had never undergone biopsy. Cancer detection rate on TMRI-GB was 57% for PTs with a prior diagnosis of PCa, 50% for PTs with a history of benign biopsy, and 67% who were biopsy naïve. An average of 3.16 cores were sampled from malignant lesions and an average of 2.74 were sampled from benign lesions (P=0.02). TMRI-GB has a higher cancer detection rate than TRUS-GB. TMRI-GB may have a critical role as a tool for active surveillance, tumor mapping, and primary detection of PCa, which will likely evolve as the ability to identify malignant lesions improve. The roles of pathologists and radiologists in the validation of this procedure will continue to be even more vital in the future.

We retrospectively evaluated the prognostic significance of polypharmacy and inappropriate medication use among 150 patients >60 years of age receiving induction chemotherapy for acute myelogenous leukemia (AML). After adjustment for age and comorbidity, increased number of medications at diagnosis (≥ 4 versus ≤ 1) was associated with increased 30-day mortality (OR=9.98, 95% CI=1.18-84.13), lower odds of complete remission status (OR=0.20, 95% CI=0.06-0.65), and higher overall mortality (HR=2.13, 95% CI=1.15-3.92). Inappropriate medication use (classified according to Beers criteria) was not significantly associated with clinical outcomes. Polypharmacy warrants further study as a modifiable marker of vulnerability among older adults with AML.

BACKGROUND: Aprotinin is the only Food and Drug Administration-approved agent to reduce haemorrhage related to cardiac surgery and its safety and efficacy has been extensively studied. Our study sought to compare the efficacy, early and late mortality and major morbidity associated with aprotinin compared with e-aminocaproic acid (EACA) in cardiac surgery operations. METHODS: Between January 2002 and December 2006, 2101 patients underwent coronary artery bypass grafting (CABG), valve surgery or CABG and valve surgery in our institution with the use of aprotinin (1898 patients) or EACA (203 patients). Logistic regression and propensity score analysis were used to adjust for imbalances in the patients' preoperative characteristics. The propensity score-adjusted sample included 570 patients who received aprotinin and 114 who received EACA (1-5 matching). RESULTS: Operative mortality was higher in the aprotinin group in univariate (aprotinin 4.3% vs EACA 1%, p=0.023) but not propensity score-adjusted multivariate analysis (4% vs 0.9%, p=0.16). In propensity score-adjusted analysis, aprotinin was also associated with a lower rate of blood transfusion (38.8% vs 50%, p=0.04), a lower rate of haemorrhage-related re-exploration (3.7% vs 7.9%, p=0.04) and a higher risk of in-hospital cardiac arrest (3.7% vs 0%, p=0.03) and a marginally but not statistically significantly higher risk of acute renal failure (6.8% vs 2.6%, p=0.09). In Cox proportional hazards regression analysis, the risk of late death was higher in the aprotinin compared to EACA group (hazard ratio=4.33, 95% confidence interval (CI)=1.60-11.67, p=0.004). CONCLUSION: Aprotinin decreases the rate of postoperative blood transfusion and haemorrhage-related re-exploration, but increases the risk of in-hospital cardiac arrest and late mortality after cardiac surgery when compared to EACA. Cumulative evidence suggests that the risk associated with aprotinin may not be worth the haemostatic benefit.

BACKGROUND: Early tracheal extubation is a common goal after cardiac surgery and may improve postoperative outcomes. Our study evaluates the impact of a quality improvement program (QIP) on early extubation, pulmonary complications, and resource utilization after cardiac surgery. METHODS: Between 2002 and 2006, 980 patients underwent early tracheal extubation (<6 hours after surgery) and 1231 had conventional extubation (> 6 hours after surgery, conventional group). Outcomes compared between the two groups included: (1) pneumonia, (2) sepsis, (3) intensive care unit (ICU) length of stay, (4) hospital length of stay, (5) ICU readmission, and (6) reintubation. Logistic regression analysis and propensity score adjustment were used to adjust for imbalances in the patients' preoperative characteristics. RESULTS: Early extubation rates were significantly increased with QIP (QIP 53% vs. Non-QIP 38%, p = 0.01). Early extubation was associated with a lower rate of (1) pneumonia (odds ratio [OR]= 0.35, 95% confidence intervals [CI]= 0.22-0.55, p <0.001), (2) sepsis (OR = 0.38, CI = 0.20-0.74, p <0.004), (3) prolonged ICU length of stay (OR = 0.42, CI = 0.35-0.50, p <0.001), (4) hospital length of stay (OR = 0.37, CI = 0.29-0.47, p <0.001), (5) ICU readmission (OR = 0.55, CI = 0.39-0.78, p <0.001), and (6) reintubation (OR = 0.53, CI = 0.34-0.81, p <0.003) both in multivariable logistic regression analysis and propensity score adjustment. CONCLUSIONS: QIP and early tracheal extubation reduce pulmonary complications and resource utilization after cardiac surgery.

The aim of this study was to investigate how a continuous quality improvement (CQI) program affected major morbidity and postoperative outcomes after cardiac surgery. Patients were divided into 2 groups: those who underwent surgery (coronary artery bypass grafting, isolated valve surgery, or coronary artery bypass grafting and valve surgery) after the establishment of a CQI program (from January 2005 to December 2006, n = 922) and those who underwent surgery beforehand (from January 2002 to December 2003, n = 1,289). Patients who had surgery in 2004, when the system and processes were reengineered, were not included in the analysis. Outcomes compared between the 2 groups included (1) acute renal failure, (2) stroke, (3) sepsis, (4) hemorrhage-related reexploration, (5) cardiac tamponade, (6) mediastinitis, and (7) prolonged length of stay. Logistic regression analysis and propensity score adjustment were used to adjust for imbalances in the patients' preoperative characteristics. After propensity score adjustment, CQI was found to decrease the rate of sepsis (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.3 to 0.9, p = 0.02) and cardiac tamponade (OR 0.2, 95% CI 0.04 to 0.8, p = 0.02) but to only marginally decrease the rate of acute renal failure (OR 0.7, 95% CI 0.5 to 1.0, p = 0.07). CQI did not emerge as an independent risk factor for hemorrhage-related reexploration, prolonged length of stay, mediastinitis, or stroke in either multivariate logistic regression analysis or propensity score adjustment. In conclusion, the systematic implementation of a CQI program and the application of multidisciplinary protocols decrease sepsis and cardiac tamponade after cardiac surgery.
