An Elusive Diagnosis: Diffuse Large B-Cell Lymphoma Masquerading as Acute Liver Failure with Persistent Lactic Acidosis. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e941270. [PMID: 37870994 PMCID: PMC10614429 DOI: 10.12659/ajcr.941270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 09/06/2023] [Accepted: 08/24/2023] [Indexed: 10/25/2023]
Abstract
BACKGROUND Acute liver failure (ALF) associated with malignant lymphoma is a rare condition with non-specific clinical and radiological features. Here, we describe an unusual case of ALF due to DLBCL with an image negative on presentation posing diagnostic difficulty. CASE REPORT A 74-year-old man was admitted to our hospital with abdominal pain. Radiological and laboratory investigations revealed lymphadenopathy with mildly elevated transaminitis and alkaline phosphates levels. A right upper-quadrant ultrasound showed heterogeneous hepatic parenchyma. Eight days later, he had worsening abdominal pain. He was found to have altered mental status and asterixis. His liver function was worsened with ALT 101, AST 328, lactic acid 4.2, total bilirubin 2.5, INR 6.35, and ammonia level 117 µmol/L. He continued to deteriorate with worsening lactic acidosis, coagulopathy, severe anemia, elevated liver enzymes, and thrombocytopenia. Unfortunately, the patient died of multi-organ failure on the 14th day of hospitalization. The autopsy findings revealed DLBCL involving multiple organs, including the liver, lung, bone marrow, and multiple lymph nodes. Despite an extensive diagnostic workup, an underlying diagnosis was unable to be established antemortem. CONCLUSIONS We describe a case of ALF linked to DLBCL discovered at autopsy. The non-specific clinical and radiological features of this condition make diagnosis challenging, and the prognosis is often poor. Further research and awareness are needed to improve the early detection and management of ALF associated with malignant lymphoma. By expanding the literature on this topic, we aim to improve outcomes and optimize patient care in similar clinical scenarios.

Abstract
Sarcoidosis is a systemic granulomatous disease characterized by the hyperactivation of CD4 T cells, CD8 T cells, and macrophages. Clinical presentations of sarcoidosis are highly variable. Sarcoidosis is unknown in its etiology, but it suggests it may result from exposure to specific environmental agents in genetically susceptible people. Sarcoidosis commonly involves the lungs and lymphoid system. Bone marrow involvement in sarcoidosis is uncommon. Sarcoidosis rarely results in intracerebral hemorrhage due to severe thrombocytopenia secondary to bone marrow involvement. We present the case of a 72-year-old woman who has been in remission from sarcoidosis for 15 years and developed intracerebral hemorrhage secondary to severe thrombocytopenia due to sarcoidosis recurrence in the bone marrow. The patient presented to the emergency department with a generalized, non-blanching petechiae rash and nose and gum bleeding. Her labs showed a platelet count of less than 10.000/mcL, and computed tomography (CT) showed intracerebral hemorrhage. A bone marrow biopsy revealed a small, non-caseating granuloma indicative of a sarcoidosis relapse in the bone marrow.

Abstract
Abstract
Introduction: The incidence of triple negative breast cancer (TNBC) in West Africa appears to mirror the higher incidence of the disease among African American women in the United States. However, there remains a paucity of molecular data on TNBC from sub-Saharan Africa, despite the emergence of effective immunotherapies. Methods: Consecutive patients diagnosed with invasive breast cancer between March 2018-Jan 2020 were identified from a prospective clinical database and paired biobank at Obafemi Awolowo University Teaching Hospital (OAUTH). All specimens were processed and fixed in formalin within 60 minutes of excision by a trained pathologist. Tissue sections (4μm thick) representative of tumor were selected for routine evaluation of estrogen, progesterone and human epidermal growth factor receptor-2 expression by immunohistochemistry. This was performed at OAUTH with adequate controls according to the ASCO/CAP guidelines and verified at an outside institution for quality assurance. Additional sections from the FFPE blocks of TNBC specimens were further stained using the Dako PharmDx 22C3 PD-L1 commercial assay according to manufacturer protocols at Dalhousie University. External on-slide controls included tonsil, PD-L1 negative TNBC, and PD-L1 positive TNBC. PD-L1 expression was scored using the combined positive score (CPS), which is the number of 22C3 staining tumour cells, lymphocytes, and macrophages divided by the number of viable tumour cells, multiplied by 100. The threshold for a positive result was a CPS of ≥10 as per manufacturer instructions and institutional protocol. Research ethics board approval as well as data and material transfer agreements between institutions was obtained for this study. Results: From 85 cases, 32 were TNBC (37.6%). The mean age and BMI were 49.6±SD 7.7 and 26.2±5.7, respectively. The majority of patients presented with locally advanced disease (64.2% Stage III, 14.2% Stage IV). Seventy-nine percent (78.5%) of patients received an average of five cycles of neoadjuvant chemotherapy (SD 2.3). From 32 TNBC specimens, 27 had available FFPE tissue blocks, and of those, 24 had interpretable PD-L1 IHC for inclusion in the analysis. A total of 37.5% (9/24) of cases demonstrated a CPS ≥10. Conclusions: Over a third of breast cancer specimens in this Nigerian cohort were triple negative, 37.5% of which had PD-L1 CPS scores of ≥10. These results suggest a large proportion of patients in Nigeria may benefit from access to immunotherapy. This is the first reported incidence of PD-L1 expression in breast cancer from sub-Saharan Africa.

Abstract
Gallbladder carcinoma (GBC) is the most common of all biliary tract cancers. GBC is a multifactorial disease. Gallbladder dysplasia from any gallbladder inflammatory condition is one of the main risk factors for GBC. The late diagnosis of GBC is a major problem in its treatment. It is treated by radical resection and the prognosis is improved by adjuvant chemoradiation. We present a rare case of gall bladder cancer presenting as hepatic abscesses with severe sepsis. An 83-year-old male presented with progressive symptoms of shakiness, general weakness, vomiting, and profuse diarrhea. Lab work revealed deranged liver enzymes. Computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) abdomen revealed intrahepatic abscesses contiguous with the gallbladder lumen through a gallbladder wall defect and cholecystitis of unknown chronicity. Subsequently, he underwent central hepatectomy and the pathology report of the sample as well as endoscopic retrograde cholangiopancreatography (ERCP) brushings revealed gallbladder adenocarcinoma. The case was complicated by biloma, acute renal failure, and the development of malignant ascites, and the patient died almost four months after the diagnosis of gallbladder cancer.

Developing a Technology Acceptability and Usage Survey (TAUS) for mHealth Intervention Planning and Evaluation in Nigeria: Pilot Study. JMIR Form Res 2022; 6:e34035. [PMID: 35442204 PMCID: PMC9069275 DOI: 10.2196/34035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 12/10/2021] [Accepted: 12/29/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Technology acceptability and usage surveys (TAUS) are brief questionnaires that measure technology comfort, typical daily use, and access in a population. However, current measures are not adapted to low- and middle-income country (LMIC) contexts. OBJECTIVE The objective of this pilot study was to develop a TAUS that could be used to inform the implementation of a mobile health (mHealth) intervention in Nigeria. METHODS A literature review of validated technology comfort and usage scales was conducted to identify candidate items. The draft measure was reviewed for face validity by an expert panel comprised of clinicians and researchers with cultural, methodological, and clinical expertise. The measure was piloted by radiologists at an oncology symposium in Nigeria. RESULTS After expert review, the final measure included 18 items organized into 3 domains: (1) comfort with using mobile applications, (2) reliability of internet or electricity, and (3) attitudes toward using computers or mobile applications in clinical practice. The pilot sample (n=16) reported high levels of comfort and acceptability toward using mHealth applications in the clinical setting but faced numerous infrastructure challenges. CONCLUSIONS Pilot results indicate that the TAUS may be a feasible and appropriate measure for assessing technology usage and acceptability in LMIC clinical contexts. Dedicating a domain to technology infrastructure and access yielded valuable insights for program implementation.

HMGA2 Immunoexpression is frequent in salivary gland pleomorphic adenoma: immunohistochemical and molecular analyses of PLAG1 and HMGA2 in 25 cases. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2022; 15:63-71. [PMID: 35265254 PMCID: PMC8902481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 12/22/2021] [Indexed: 06/14/2023]
Abstract
The main oncologic events in pleomorphic adenoma (PA) are the translocations of Pleomorphic adenoma gene 1 (PLAG1) on chromosome 8q12 and High-mobility group AT-hook 2 (HMGA2) on chromosome 12q14.3 with various fusion partners. These translocations result in the transcriptional up-regulation of PLAG1 and HMGA2 proteins. We carried out a preliminary evaluation of PLAG1 translocation by fluorescence in-situ hybridization (FISH), immunohistochemistry (IHC) and HMGA2 IHC on twenty-five archived formalin-fixed paraffin-embedded tissues of PAs and its clinicopathologic features. Only eight cases were successfully hybridized and 50% of the interpretable cases were considered positive for PLAG1 translocation. PLAG1 IHC was only positive in 2 (8%) of the 25 cases stained, including one of the positive PLAG1 translocation cases. HMGA2 IHC was positive in 12 (48%) of the 25 cases stained including 2 (50%) of the 4 cases identified with PLAG1 translocation by FISH, 3 (75%) of the 4 cases negative for PLAG1 translocation by FISH and 7 (41%) of the 17 cases with failed hybridization. Overall, 15 (60%) of the 25 PA cases demonstrated PLAG1 and/or HMGA2 alterations confirmed either by FISH or IHC. In conclusion, PLAG1 and HMGA2 alterations were confirmed either by FISH or IHC in this cohort and HMGA2 alteration is a common event in PAs of salivary gland.

Nontuberculous Mycobacterial Infection Mimicking Inflammatory Tenosynovitis: A Real Head Scratcher. Cureus 2021; 13:e20845.

Abstract
Nontuberculous mycobacterial tenosynovitis is a rare entity that is often misdiagnosed as bacterial or inflammatory tenosynovitis. We present a case of a 64-year-old man who presented with pain and swelling of his right wrist for several weeks. Magnetic resonance imaging (MRI) of his right upper extremity showed findings consistent with prominent tenosynovitis in the right extensor digitorum tendon sheath. Surgical debridement showed reactive histopathology with negative Gram stain, culture, and acid-fast bacilli stain; after which, steroids were started along with methotrexate and hydroxychloroquine, which was later changed to anti-tumor necrosis factor (anti-TNF) therapy. Due to minimal improvement, repeat operative debridement was done showing macroscopic rice bodies with pathology revealing chronic granulomatous inflammation with necrosis. However, repeated infectious work-up remained negative. After his symptoms progressed to involve his right index finger, his tenosynovium was sampled again, which was positive for acid-fast bacilli (AFB) staining for rare mycobacterial organisms, with cultures growing faint transparent colonies that were sent to the state laboratory for speciation. He was started on empiric therapy with clarithromycin, ethambutol, and rifampin following which his wound fully healed. This case illustrates the insidious course of nontuberculous mycobacteria (NTM) tenosynovitis leading to delayed diagnosis along with unwarranted treatments that could be harmful. Open tissue biopsy is important in the context of a lack of clinical response to common treatment modalities, in the absence of an alternative diagnosis with a similar clinical picture.

Abstract
Introduction/Objective We performed a retrospective analysis of test volumes in clinical pathology prior to and during the COVID-19 pandemic to better understand the impact of the pandemic on our laboratory utilization. Methods/Case Report The laboratory information system was queried for test order volume in 2019 and 2020 using Discern Analytics 2.0. Representative tests including C-reactive protein (CRP), D-dimer, fibrinogen, ferritin, lactate dehydrogenase (LDH), procalcitonin, prothrombin time (PT), point of care iSTAT blood gas analysis, ABO and Rhesus typing (ABORh), antibody screening, flow cytometry, and serum protein electrophoresis (SPEP). Data was analyzed using Microsoft Excel 2013. Results (if a Case Study enter NA) The data showed an increase in the number of tests ordered and verified in the in-patient setting. The increase was most substantial for D-dimer, CRP and LDH with a percentage increase of approximately 200% on each test from year 2019 to 2020. An increase of 73% and 57% was noted for ferritin and fibrinogen respectively. A slight decrease in volume was noted for tests ordered in the out-patient setting including SPEPs during the pandemic. There was no significant change in the number of orders verified for point of care ISTAT blood gas testing between 2019 and 2020. Procalcitonin test volume increased steadily from its implementation in May 2020 with a steep rise in test volume in November and December. A total of 75,295 SARS-CoV-2 molecular tests were ordered between March and December 2020 with approximately 80% of the orders being performed as a send- out test. Conclusion The COVID-19 pandemic has had a substantial impact on laboratory utilization with significant volume increases in tests that guide the management of hospitalized COVID-19 patients and slight decrease in tests ordered mostly in the outpatient setting. These results may help guide current and future decisions relating to laboratory operations during pandemics.

Opportunities for Improvement in the Administration of Neoadjuvant Chemotherapy for T4 Breast Cancer: A Comparison of the U.S. and Nigeria. Oncologist 2021; 26:e1589-e1598. [PMID: 33955123 DOI: 10.1002/onco.13814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Accepted: 04/08/2021] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is an integral component of T4 breast cancer (BCa) treatment. We compared response to NAC for T4 BCa in the U.S. and Nigeria to direct future interventions. MATERIALS AND METHODS Cross-sectional retrospective analysis included all patients with non-metastatic T4 BCa treated from 2010 to 2016 at Memorial Sloan Kettering Cancer Center (New York, New York) and Obafemi Awolowo University Teaching Hospitals Complex (Ile Ife, Nigeria). Pathologic complete response (pCR) and survival were compared and factors contributing to disparities evaluated. RESULTS Three hundred and eight patients met inclusion criteria: 157 (51%) in the U.S. and 151 (49%) in Nigeria. All U.S. patients received NAC and surgery compared with 93 (62%) Nigerian patients. Fifty-six out of ninety-three (60%) Nigerian patients completed their prescribed course of NAC. In Nigeria, older age and higher socioeconomic status were associated with treatment receipt. Fewer patients in Nigeria had immunohistochemistry performed (100% U.S. vs. 18% Nigeria). Of those with available receptor subtype, 18% (28/157) of U.S. patients were triple negative versus 39% (9/23) of Nigerian patients. Overall pCR was seen in 27% (42/155) of U.S. patients and 5% (4/76) of Nigerian patients. Five-year survival was significantly shorter in Nigeria versus the U.S. (61% vs. 72%). However, among the subset of patients who received multimodality therapy, including NAC and surgery with curative intent, 5-year survival (67% vs. 72%) and 5-year recurrence-free survival (48% vs. 61%) did not significantly differ between countries. CONCLUSION Addressing health system, socioeconomic, and psychosocial barriers is necessary for administration of complete NAC to improve BCa outcomes in Nigeria. IMPLICATIONS FOR PRACTICE This cross-sectional retrospective analysis of patients with T4 breast cancer in Nigeria and the U.S. found a significant difference in pathologic complete response to neoadjuvant chemotherapy (5% Nigeria vs. 27% U.S.). Five-year survival was shorter in Nigeria, but in patients receiving multimodality treatment, including neoadjuvant chemotherapy and surgery with curative intent, 5-year overall and recurrence-free survival did not differ between countries. Capacity-building efforts in Nigeria should focus on access to pathology services to direct systemic therapy and promoting receipt of complete chemotherapy to improve outcomes.

NR4A3 (NOR-1) Immunostaining Shows Better Performance than DOG1 Immunostaining in Acinic Cell Carcinoma of Salivary Gland: a Preliminary Study. EJOURNAL OF ORAL MAXILLOFACIAL RESEARCH 2021; 12:e4. [PMID: 33959239 PMCID: PMC8085676 DOI: 10.5037/jomr.2021.12104] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 02/24/2021] [Indexed: 12/13/2022]
Abstract
Objectives Acinic cell carcinoma of salivary gland harbours recurrent and specific chromosomal rearrangement [t(4;9)(q13;q31)], resulting in the translocation of secretory calcium-binding phosphoprotein gene cluster at 4q13 to nuclear receptor subfamily 4 group a member 3 at 9q31. This upregulates the transcription factor nuclear receptor subfamily 4 group A member 3, which can be detected by immunohistochemistry. The purpose of this pilot study is to evaluate the performance of nuclear receptor subfamily 4 group A member 3 immunostaining on whole-slide acinic cell carcinoma tissue, in comparison with discovered on GIST-1 immunostaining. Material and Methods We retrieved 6 cases of acinic cell carcinoma (AciCC), including 5 conventional low-grade and 1 dedifferentiated high-grade. Immunohistochemistry (IHC) for nuclear receptor subfamily 4 group A member 3 (NR4A3) and discovered on GIST-1 (DOG1) were performed at the University of Pittsburgh Medical Centre in Pittsburgh, Pennsylvania on all retrieved cases. Results The result shows that NR4A3 IHC shows better performance than DOG1 IHC: 5 of the 6 (83.3%) AciCC cases (including the dedifferentiated high-grade) demonstrated strong diffuse nuclear staining for NR4A3, also five AciCC cases (including the dedifferentiated high-grade) demonstrated weak to moderate membranous staining with variable distribution for DOG1. Moreover, only 3 (50%) cases showed complete membranous staining with DOG1. Conclusions This pilot study showed that nuclear receptor subfamily 4 group A member 3 immunostaining is a sensitive marker for acinic cell carcinoma and of better utility than discovered on GIST-1 immunostaining in making a diagnosis of acinic cell carcinoma.

Abstract
High-quality data are needed to guide interventions aimed at improving breast cancer outcomes in sub-Saharan Africa. We present data from an institutional breast cancer database to create a framework for cancer policy and development in Nigeria. An institutional database was queried for consecutive patients diagnosed with breast cancer between January 2010 and December 2018. Sociodemographic, diagnostic, histopathologic, treatment and outcome variables were analyzed. Of 607 patients, there were 597 females with a mean age of 49.8 ± 12.2 years. Most patients presented with a palpable mass (97%) and advanced disease (80.2% ≥ Stage III). Immunohistochemistry was performed on 21.6% (131/607) of specimens. Forty percent were estrogen receptor positive, 32.8% were positive for HER-2 and 43.5% were triple negative. Surgery was performed on 49.9% (303/607) of patients, while 72% received chemotherapy and 7.9% had radiotherapy. At a median follow-up period of 20.5 months, the overall survival was 43.6% (95% CI -37.7 to 49.5). Among patients with resectable disease, 18.8% (57/303) experienced a recurrence. Survival was significantly better for early-stage disease (I and II) compared to late-stage disease (III or IV) (78.6% vs 33.3%, P < .001). Receipt of adjuvant radiotherapy after systemic chemotherapy was associated with improved survival in patients with locally advanced disease (68.5%, CI -46.3 to 86 vs 51%, CI 38.6 to 61.9, P < .001). This large cohort highlights the dual burden of advanced disease and inadequate access to comprehensive breast cancer care in Nigeria. There is a significant potential for improving outcomes by promoting early diagnosis and facilitating access to multimodality treatment.

Abstract
Social scientists have advocated for the use of participatory research methods for Global Health project design and planning. However, community-engaged approaches can be time and resource-intensive. This article proposes a feasible framework for conducting a participatory needs assessment in time-limited settings using multiple, triangulated qualitative methods. This framework is outlined through a case study: a participatory needs assessment to inform the design of an ultrasound-guided biopsy training program in Nigeria. Breast cancer is the leading cause of death for Nigerian women and most cases in Nigeria are diagnosed at an advanced stage; timely diagnosis is impeded by fractious referral pathways, costly imaging equipment, and limited access outside urban centers. The project involved participant observation, surveys, and focus groups at the African Research Group for Oncology (ARGO) in Ile-Ife, Nigeria. Through this timely research and engagement, participants spoke about diagnostic challenges, institutional power dynamics, and infrastructure considerations for program implementation.
