RESUMO

Drug reaction with eosinophilia and systemic symptoms (DRESS) is an adverse reaction to medications such as sulfonamide-containing antibiotics, anticonvulsants, vancomycin, and non-steroidal anti-inflammatory drugs (NSAIDs). It typically presents with a characteristic rash, eosinophilia, and visceral organ failure. Patients who do not present with characteristic features of DRESS are at risk for delayed diagnosis and treatment. Early diagnosis of DRESS is imperative in preventing unfavorable outcomes such as multi-organ involvement and death. This case report presents the case of a patient who was diagnosed with DRESS but did not display a classic presentation.

RESUMO

Rheumatoid arthritis is a chronic inflammatory condition with many manifestations primarily presenting in older female patients with joint stiffness. Quadriplegia associated with rheumatoid arthritis is common and can occur secondary to spinal cord compression from atlantoaxial dislocation. In contrast, functional quadriplegia is rare and has not been previously reported as an initial manifestation of rheumatoid arthritis. We report the case of a 56-year-old male with a past medical history of carotid artery stenosis, hypertension, and tobacco and alcohol misuse who presented to the emergency department with a five-month history of progressive bilateral shoulder pain and weakness resulting in functional quadriplegia. The patient required inpatient hospital admission for further evaluation of his functional quadriplegia and associated symptoms. His workup was significant for rheumatoid arthritis, and he was successfully treated with high-dose steroids and received physical and occupational therapy during admission. Prior to discharge, the patient was initiated on methotrexate therapy and appointed a follow-up with primary care and rheumatology. The purpose of this study is to facilitate early clinical recognition of a common disease with unique and underreported symptomatology.

RESUMO

Background Prostatic ductal adenocarcinoma (DAC) is an aggressive histologic variant of prostate cancer that often warrants multimodal therapy and poses a significant diagnostic challenge clinically and at imaging. Purpose To develop multiparametric MRI criteria to define DAC and to assess their diagnostic performance in differentiating DAC from prostatic acinar adenocarcinoma (PAC). Materials and Methods Men with histologically proven DAC who had multiparametric MRI before radical prostatectomy were retrospectively identified from January 2011 through November 2018. MRI features were predefined using a subset of nine DACs and then compared for men with peripheral-zone DACs 1 cm or greater in size and men with matched biopsy-confirmed International Society of Urological Pathology grade group 4-5 PAC, by four independent radiologists blinded to the pathologic diagnosis. Diagnostic performance was determined by consensus read. Patient and tumor characteristics were compared by using the Fisher test, t-tests, and Mann-Whitney U test. Agreement (Cohen κ) and sensitivity analyses were also performed. Results There were 59 men with DAC (median age, 63 years [interquartile range, 56, 67 years]) and 59 men with PAC (median age, 64 years [interquartile range, 59, 69 years]). Predefined MRI features, including intermediate T2 signal, well-defined margin, lobulation, and hypointense rim, were detected in a higher proportion of DACs than PACs (76% [45 of 59] vs 5% [three of 59]; P < .001). On consensus reading, the presence of three or more features demonstrated 76% sensitivity, 94% specificity, 94% positive predictive value [PPV], and 80% negative predictive value [NPV] for all DACs and 100% sensitivity, 95% specificity, 81% PPV, and 100% NPV for pure DACs. The DACs and PACs showed no difference in contrast enhancement (100% vs 100%; P >.99, median T2 signal intensity (254 vs 230; P = .99), or apparent diffusion coefficient (median, 677 10-6 mm2/sec vs 685 10-6 mm2/sec; P = .73). Conclusion The presence of intermediate T2 signal, well-defined margin, lobulation, and/or hypointense rim, together with restricted diffusion and contrast enhancement at multiparametric MRI of the prostate, suggests prostatic ductal adenocarcinoma rather than prostatic acinar adenocarcinoma. © RSNA, 2022 Online supplemental material is available for this article.

RESUMO

BACKGROUND: Ductal prostate adenocarcinoma (DAC) is a rare, aggressive, histologic variant of prostate cancer that is treated with conventional therapies, similar to high-risk prostate adenocarcinoma (PAC). OBJECTIVE: To assess the outcomes of men undergoing definitive therapy for DAC or high-risk PAC and to explore the effects of androgen deprivation therapy (ADT) in improving the outcomes of DAC. DESIGN, SETTING, AND PARTICIPANTS: A single-center retrospective review of all patients with cT1-4/N0-1 DAC from 2005 to 2018 was performed. Those undergoing radical prostatectomy (RP) or radiotherapy (RTx) for DAC were compared with cohorts of high-risk PAC patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Metastasis-free survival (MFS) and overall survival (OS) rates were analyzed using Kaplan-Meier and Cox regression models. RESULTS AND LIMITATIONS: A total of 228 men with DAC were identified; 163 underwent RP, 34 underwent RTx, and 31 had neoadjuvant therapy prior to RP. In this study, 163 DAC patients and 155 PAC patients undergoing RP were compared. Similarly, 34 DAC patients and 74 PAC patients undergoing RTx were compared. DAC patients undergoing RP or RTx had worse 5-yr MFS (75% vs 95% and 62% vs 93%, respectively, p < 0.001) and 5-yr OS (88% vs 97% and 82% vs 100%, respectively, p < 0.05) compared with PAC patients. In the 76 men who received adjuvant/salvage ADT after RP, DAC also had worse MFS and OS than PAC (p < 0.01). A genomic analysis revealed that 10/11 (91%) DACs treated with ADT had intrinsic upregulation of androgen-resistant pathways. Further, none of the DAC patients (0/15) who received only neoadjuvant ADT prior to RP had any pathologic downgrading. The retrospective nature was a limitation. CONCLUSIONS: Men undergoing RP or RTx for DAC had worse outcomes than PAC patients, regardless of the treatment modality. Upregulation of several intrinsic resistance pathways in DAC rendered ADT less effective. Further evaluation of the underlying biology of DAC with clinical trials is needed. PATIENT SUMMARY: This study demonstrated worse outcomes among patients with ductal adenocarcinoma of the prostate than among high-grade prostate adenocarcinoma patients, regardless of the treatment modality.

RESUMO

BACKGROUND: The current study was conducted to investigate the patterns of metastases in men with metastatic prostatic ductal adenocarcinoma (DAC) and recurrence patterns after therapy. METHODS: All patients with a new diagnosis of DAC with de novo metastases and those with localized disease who developed metastases after treatment and were treated at the study institution from January 2005 to November 2018 were included. All patient and tumor characteristics and outcome data were collected. RESULTS: A total of 164 patients (37.7%) had metastatic DAC, including 112 with de novo metastases and 52 who developed metastases after treatment. Men with de novo metastases were found to have a significantly higher median prostate-specific antigen level and International Society of Urological Pathology grade but a lower cT3 and/or T4 classification compared with those with metastases that developed after treatment (all P < .05). Approximately 87% of men with de novo metastases progressed despite multiple systemic therapies, 37.6% required intervention for the palliation of symptoms, and 10.1% responded to systemic therapy and underwent treatment of the primary tumor. Men with de novo metastatic DAC and those who developed metastases after treatment had multiple metastatic sites (including bone and viscera), with higher rates of lung metastases noted in the posttreatment group (23.2% vs 44.2%; P = .01). A total of 45 patients who were treated with curative intent developed metastases at a median of 22 months (range, 0.9-74.8 months) after treatment, at low prostate-specific antigen levels (median, 4.4 ng/mL [interquartile range, 1.7-11.1 ng/mL]). CONCLUSIONS: The current study described the metastatic patterns of DAC in both patients with de novo metastatic disease and those who later progress to metastases. Men receiving treatment for DAC with curative intent require stringent long-term follow-up with imaging modalities, including chest imaging given the predilection toward lung metastases noted among these patients.

RESUMO

Adrenocortical carcinoma (ACC) is a rare malignancy whose risk factors are unclear. We explored the association of ACC risk with exposure to selected environmental factors, with a focus on cigarette smoking. We conducted a hospital-based case-control study at The University of Texas MD Anderson Cancer Center. Cases (n = 432) patients with ACC treated at MD Anderson, and controls (n = 1,204) were healthy and genetically unrelated spouses of patients at MD Anderson who had cancers not associated with smoking. Information on the subjects' demographic features and selected risk factors was collected using a structured, validated questionnaire and medical records review. Unconditional logistic regression was used to calculate adjusted odds ratios (AORs) via the maximum-likelihood method. Cases had a younger mean (± standard deviation) age than did controls (47.0 ± 0.7 and 60.0 ± 0.3 years, respectively), and the majority of cases were female (60.6%) and non-Hispanic white (82.4%). We found a markedly increased risk of ACC among male cigarette smokers, with an AOR = 1.8 (95% confidence interval [CI] =1.2-2.9), but not among female smokers (AOR = 1.1, 95% CI = 0.7-1.6). Family history of cancer was associated with increased risk of ACC (AOR = 2.8, 95% CI 1.9-4.3) and in both men and women, whereas alcohol consumption was associated with reduced risk in men (AOR = 0.2, 95% CI = 0.1-0.3) but not women (AOR = 0.7, 95% CI = 0.5-1.1). Understanding these risk factors and their underlying mechanisms may help prevent ACC in susceptible individuals and eventually identify new therapeutic options for ACC.

RESUMO

This study was conducted to determine the compatibility of Contans® (Coniothyrium minitans) with fungicides against Sclerotinia sclerotiorum. Results showed that both Contans® and Topsin® significantly reduced the disease incidence caused by S. sclerotiorum by 90% and 95% survival plants, respectively when they were individually applied and compared to control. While, soil application of Contans® and Sumisclex mixture was the most effective in suppressing the white rot disease incidence that produced 100% survival plants, application of C. minitans combined with the reduced doses of fungicides would be advantageous in saving labor cost, thus increasing production efficiency of bean.
