Trends in Positive Surgical Margins in cT1‐T2 Oral Cavity Squamous Cell Carcinoma

xlomafota13 shared this article with you from Inoreader Trends in Positive Surgical Margins in cT1‐T2 Oral Cavity Squamous Cell Carcinoma Via The Laryngoscope Objectives/Hypothesis To evaluate trends in contemporary positive surgical margin incidence in cT1-T2 oral cavity squamous cell carcinoma and to evaluate factors associated with surgical margin status. Study Design Retrospective analysis of large dataset. Methods Retrospective analysis of the National Cancer Database. Results Between 2004 and 2016, 39,818 patients with cT1 or cT2 oral cavity squamous cell carcinoma received primary curative-intent surgery. Positive surgical margins were present in 7.95% of patients, and univariable adjusted probability of positive surgical margins over the study period declined by 1% per year (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98–1.0; P = .049). Multivariable regression revealed the annual rate of positive surgical margins declined significantly (OR, 0.95 per year; 95% CI, 0.92–0.97; P < .001). Factors associated with increased odds of positive surgical margins included cT2 disease, subsite, understaged disease, lymphovascular invasion, tumor grade, and positive lymph nodes. Race and socioeconomic status were not associated with surgical margin status. Treatment at an academic center was associated with increased time to definitive surgery (median 35 days IQR 22–50 vs. median 27 days IQR 14–42; P&nb sp;< .001) and a 20% reduction in positive surgical margin rate (OR, 0.80; 95% CI, 0.71–0.90; P < .001). Treatment at high-volume centers was less likely to be associated with positive surgical margins (OR, 0.85; 95% CI, 0.74–0.98; P = .02). Conclusion Surgical subsite, clinical T and N category, presence of lymphovascular invasion, and histologic grade were independent predictors of positive surgical margins. Patients are increasingly being treated at high-volume and academic centers. Overall, the rate of positive surgical margins in cT1-T2 oral cavity squamous cell carcinoma is decreasing.

The 'hyperdense basivertebral vein' sign: another marker of a CSF-venous fistula

xlomafota13 shared this article with you from Inoreader The "hyperdense basivertebral vein" sign: another marker of a CSF-venous fistula Via leak of cerebrospinal fluid Neuroradiology. 2022 Feb 1. doi: 10.1007/s00234-022-02908-x. Online ahead of print. ABSTRACT CSF-venous fistulas - initially described in 2014 - are a significant cause of spontaneous intracranial hypotension. Dynamic lateral decubitus digital subtraction and/or CT myelography typically show a hyperdense paraspinal vein. In case of a central drainage toward the internal vertebral venous plexus, it is the "hyperdense basivertebral vein" which should be searched for carefully.

Rituximab added to standard chemotherapy and its effect on minimal residual disease during induction in CD20 positive pediatric acute lymphoblastic leukemia: a pilot RCT

xlomafota13 shared this article with you from Inoreader Rituximab added to standard chemotherapy and its effect on minimal residual disease during induction in CD20 positive pediatric acute lymphoblastic leukemia: a pilot RCT Via American Journal of Blood Research Am J Blood Res. 2021 Dec 15;11(6):571-579. eCollection 2021. ABSTRACT The use of rituximab in the treatment of pediatric acute lymphoblastic leukemia (ALL) has been evaluated but mostly this has been done in the setting of a relapsed or refractory disease. Addition of rituximab to the initial treatment regimen improves the outcomes in adult CD20 positive ALL. This study was done to study its effect on newly diagnosed CD20 positive pediatric ALL patients. Twenty pediatric patients with CD20 positive ALL were randomly assigned to receive rituximab along with standard-chemotherapy [Intervention-arm (IA)] or standard-chemotherapy alone [Standard-arm (SA)]. The absolute blast count (ABC) on day 8, flowcytometry-MRD levels in the peripheral blood (PB) on day-8, day-15 and in the bone marrow (BM) at end of induction (EOI) were the outcome variables. Baseline characteristics were comparable between the IA (n=10) and SA (n=10). Significantly lo wer day-8 ABC was seen in the IA (P=0.005). The day-8 PB-MRD showed lower values for the IA but the difference wasn't significant (P=0.22). There was no difference between the IA and SA for day-15 PB-MRD and EOI BM-MRD. There was no difference in the incidence of adverse effects. Rituximab added to standard-chemotherapy lead to lower day-8 ABC and lower day-8 PB-MRD in CD20 positive pediatric ALL patients. Rituximab may be beneficial in pediatric ALL treatment. Studies with larger sample size are needed for more evidence. PMID:35103111 | PMC:PMC8784647 View on the web Inoreader.

Effects of transfusion of stored blood in patients with transfusion-dependent thalassemia

xlomafota13 shared this article with you from Inoreader Effects of transfusion of stored blood in patients with transfusion-dependent thalassemia Via American Journal of Blood Research Am J Blood Res. 2021 Dec 15;11(6):592-599. eCollection 2021. ABSTRACT OBJECTIVES: The aim of this study was to investigate the hematological and biochemical effects of stored blood transfusion on patients with transfusion-dependent thalassemia (TDT). METHODS: In this quasi-experimental study, 20-patients with TDT were enrolled. Each participant received on first visit, freshly collected red cell concentrate (RCC) (<2-days storage) and 15-days later on second visit, 7-days stored blood. Blood samples were obtained immediately before and 24-hours after each transfusion. Differences in the Complete blood counts, bilirubin, LDH, C-Reactive protein, ferritin, and iron levels in the pre- and post-transfusion samples were compared between the first and second transfusion. RESULTS: Fresh blood transfusion resulted in a higher (but non-significant) increase in hemoglobin and other red cell parameters. Notably, a significant incre ase in white cell counts (WCC) was seen in 7-days stored blood vs fresh blood (1.82×109/l vs 1.01×109/l, P=0.002). No statistically significant difference was found in LDH, direct and indirect bilirubin, creatinine, blood glucose, serum uric acid, serum ferritin, and serum Iron levels. There was a statistically significant rise in C-reactive protein levels in stored (6.43±7.46 mg/dl) versus fresh RCC (1.89±2.38 mg/dl), p-value =0.012. CONCLUSIONS: We show that in patients with chronic TDT, an increase in inflammation-associated markers (WCC and CRP) is observed. Further studies to assess the extent and duration of this increase are needed. PMID:35103113 | PMC:PMC8784645 View on the web Inoreader. Take back control of your news feed.

An analysis of hematological, coagulation and biochemical markers in COVID-19 disease and their association with clinical severity and mortality: an Indian outlook

xlomafota13 shared this article with you from Inoreader An analysis of hematological, coagulation and biochemical markers in COVID-19 disease and their association with clinical severity and mortality: an Indian outlook Via American Journal of Blood Research Am J Blood Res. 2021 Dec 15;11(6):580-591. eCollection 2021. ABSTRACT BACKGROUND: The "cytokine storm" (CS) in COVID-19 leads to the worst stage of illness which can be controlled only with timely intervention. There is an urgent need to identify laboratory markers of disease progression for optimum allocation of resources in developing countries like India. METHODS: A cross-sectional study was conducted on 100 COVID-19 positive patients over two months. The cases were sub-classified based on disease severity into mild to moderate (n=61), severe (n=26) and very severe (n=13) and into survivors (n=85) and non-survivors (n=15) based on survivor status. These patients were tested for hematological parameters (total blood lymphocyte counts, NLR, PLR, platelet indices etc.), coagulation markers (D-dimer, fibrin degradation products (FDP), fibrinogen etc.) and biochemical markers (LDH, ferritin, IL-6, procalcitonin, hs-CRP). RESU LTS: Statistically significant differences were observed in hematological variables (ANC, NLR and ESR), coagulation parameters (D-dimer, FDP, fibrinogen and thrombin time) and biochemical markers (LDH, ferritin, IL-6, procalcitonin and hs-CRP) with regard to subcategories based of disease severity as well as survivor status. There was strong correlation between NLR, D-dimer, IL-6, procalcitonin and ferritin. IL-6 emerged as the single best marker of disease severity (AUC: 0.997, P=0.00), however procalcitonin, LDH, D-dimer, FDP and NLR could also predict severe disease with a good sensitivity and specificity. CONCLUSION: To conclude, study demonstrates a plethora of biomarkers which could be utilized to accurately identify the hyperinflammation and tissue damage reminiscent of cytokine storm in COVID-19 patients so that timely, safe, and effective therapies can be administered to prevent progression and potentially reduce mortality.

A review of neoplasms with MITF/MiT family translocations

xlomafota13 shared this article with you from Inoreader A review of neoplasms with MITF/MiT family translocations Via Cellular and Molecular Biology Histol Histopathol. 2022 Feb 2:18426. doi: 10.14670/HH-18-426. Online ahead of print. ABSTRACT Microphthalmia-associated transcription factor (MITF/MiT) family is a group of basic helix-loop-helix leucine zipper (bHLH-LZ) transcription factors including TFE3 (TFEA), TFEB, TFEC and MITF. The first renal neoplasms involving MITF family translocation were renal cell carcinomas with chromosome translocations involving ASPL-TFE3/t(X;17)(p11.23;q25) or MALAT1-TFEB/t(6;11)(p21.1;q12), and now it is known as MiT family translocation RCC in 2016 WHO classification. Translocations involving MITF family genes also are found in other tumor types, such as perivascular epithelioid cell neoplasm (PEComa), Alveolar soft part sarcoma (ASPS), epithelioid hemangioendothelioma, ossifying fibromyxoid tumor (OFMT), and clear cell tumor with melanocytic differentiation and ACTIN-MITF translocation. In this review, we summarize the features of different types of neoplasms with MITF family translocations. PMID:35107169 | DOI:10.14670/HH-18-426 View on the web Inoreader.

Adenoid stones, an unknown culprit in pediatric throat pain

xlomafota13 shared this article with you from Inoreader Adenoid stones, an unknown culprit in pediatric throat pain Via ear nose throat Ear Nose Throat J. 2022 Feb 2:1455613221074139. doi: 10.1177/01455613221074139. Online ahead of print. ABSTRACT We present a case of a 12-year-old male who presented with complaints of nasal congestion, intermittent throat pain, and odynophagia. He was taken to the operating room for inferior turbinate reduction and adenoidectomy and found to have stones within adenoid crypts. Adenoidectomy resulted in resolution of the patient's throat pain and pain with swallowing. Not pre viously described in the literature, adenoid stones may represent an unrecognized etiology of odynophagia and throat pain in the pediatric population. Adenoidectomy should be considered for patients symptomatic from adenoid stones. PMID:35107383 | DOI:10.1177/01455613221074139 View on the web Inoreader. Take back control of your news feed.
