RESUMEN
Uveitis is the inflammation of the uveal tract (i.e., iris, ciliary body, and choroid). Uveitis is categorized into the following three types based on the anatomical location of inflammation: anterior, intermediate, and posterior uveitis. Severe cases may lead to panuveitis, where all three layers may become inflamed potentially resulting in permanent vision loss. Uveitis can arise from different underlying disorders, including infectious causes or autoimmune disorders. Syphilis and Lyme disease are uncommon causes of uveitis. Eye involvement can occur at any stage in Lyme disease, characterized by diverse manifestations such as conjunctivitis, episcleritis, keratitis, uveitis, neuroretinitis, and retinal vasculitis. Patients may present with symptoms of blurred vision, eye pain or discomfort, visual floaters, headache, or intolerance to light. Patients can risk vision loss if not diagnosed and treated promptly.
RESUMEN
Background: Posttransplant lymphoproliferative disorder (PTLD), a term that encompasses a wide array of malignancies that occur after transplant, can be one of the most devastating transplant complications. While there have been major advancements in care, especially after the landmark PTLD-1 trial in 2012, there is a paucity of information on hospitalizations for PTLD and the changes in hospitalizations over time. Methods: This retrospective cohort study used the National Inpatient Sample to identify hospitalizations for PTLD that occurred between 2009 and 2018. We extracted data for hospitalizations with a primary or secondary diagnosis of PTLD and examined a range of variables, including age, gender, race, hospital type, hospital location, and disposition status. We also collected data on hospital region, median household income, insurance status, and bed size. Results: There was a statistically significant increase in the number of hospitalizations from 2009 to 2019 and an increasing rate of hospitalizations over the study period. Hypertension, electrolyte imbalances, renal failure, and anemia were among the most common comorbidities. We found an increased mortality rate, but this was not statistically significant. Conclusion: Our study provides insight into the changes in hospitalizations for PTLD over nearly a decade, showing an increase in hospitalizations and reports of comorbidities.
RESUMEN
The number one cause of cancer in women worldwide is breast cancer. Over the last three decades, the use of traditional screen-film mammography has increased, but in recent years, digital mammography and 3D tomosynthesis have become standard procedures for breast cancer screening. With the advancement of technology, the interpretation of images using automated algorithms has become a subject of interest. Initially, computer-aided detection (CAD) was introduced; however, it did not show any long-term benefit in clinical practice. With recent advances in artificial intelligence (AI) methods, these technologies are showing promising potential for more accurate and efficient automated breast cancer detection and treatment. While AI promises widespread integration in breast cancer detection and treatment, challenges such as data quality, regulatory, ethical implications, and algorithm validation are crucial. Addressing these is essential for fully realizing AI's potential in enhancing early diagnosis and improving patient outcomes in breast cancer management. In this review article, we aim to provide an overview of the latest developments and applications of AI in breast cancer screening and treatment. While the existing literature primarily consists of retrospective studies, ongoing and future prospective research is poised to offer deeper insights. Artificial intelligence is on the verge of widespread integration into breast cancer detection and treatment, holding the potential to enhance early diagnosis and improve patient outcomes.
RESUMEN
Methemoglobin (MetHb) is a form of hemoglobin in which iron in Hb is in an oxidized form (ferric) instead of ferrous, making it difficult to bind with oxygen. Usually, MetHb is present in small quantities (<1%) in humans, but once MetHb increases beyond 3%, the condition is known as methemoglobinemia. It can be further classified into hereditary and acquired. Hereditary forms are a rare cause of hypoxia and cyanosis. Only a few cases have been reported worldwide. Here, we present a case of a 33-year-old female with congenital methemoglobinemia who remains relatively healthy in spite of her underlying condition. This case report focuses on knowledge sharing and practical aspects of managing patients with congenital methemoglobinemia.
RESUMEN
Multiple primary malignancies (MPMs) in the same patient are rare. Over the past decade, the incidence of MPMs is increasing. The prevalence in the general population is 0.7-11.7%, with a higher incidence in the elderly. This increase in incidence can be attributed to advanced lifespan, environmental factors, early chronic disease/cancer screening, and advanced treatment leading to more metaplasia. The chances are higher in cancer patients due to the carcinogenic effect of chemoradiotherapy. Here, we present a 79-year-old female with a 27 pack-year smoking history without any significant genetic predisposition, who developed four different primary malignancies including (1) chronic lymphocytic leukemia in 2017 (stage I modified Rai), positive for CD23 and CD5, which did not require treatment; (2) melanoma in situ on the left cheek in 2019 status post excision; (3) lung adenocarcinoma with negative molecular study (epidermal growth factor receptor (EGFR)/ROS proto-oncogene, receptor tyrosine kinase (ROS)/v-Raf murine sarcoma viral oncogene homolog B1 (BRAF)/anaplastic lymphoma kinase (ALK)) and negative programmed cell death ligand 1 (PDL-1) in 2020 for which she received treatment with carboplatin, pemetrexed, and pembrolizumab; and (4) left lower pole renal mass on surveillance CT scan, which was highly suspicious for primary malignancy as opposed to metastasis, for which she underwent radical nephrectomy and biopsy positive for clear cell renal cancer. Regarding these multiple primary cancers, the thought of germline mutation was considered. But as she did not have a family history of malignancy, genetic testing was not needed as per the genetic counselor. Patients are being diagnosed with MPMs as there is more advancement in tumor detection and treatment. With the advancement in the treatment, cancer survivorship is improving. Given that there are no large studies, we believe that treatment modality for MPMs should be on a case-to-case basis and needs a multidisciplinary approach to tackle therapeutic challenges and provide radical treatment.
RESUMEN
Cervical carcinoma is one of the preventable malignancies in the United States. Age-appropriate screening has decreased the incidence of cervical cancer. A multitude of age-appropriate screening methods is available including Papanicolaou (Pap) smear cytology, human papillomavirus (HPV) DNA testing, and visual inspection tests. Patients who are not up to date with the screening can remain asymptomatic until the advanced stage like in the case of our patient. We present a 59-year-old female, who came in with progressively worsening shortness of breath on exertion, chest tightness, significant weight loss, and vaginal bleeding for the past six months. On investigations, she was found to have cannonball metastases in the lung. The patient remained critically ill during her course of hospital stay and eventually passed away.
RESUMEN
Solitary plasmacytoma is an extremely rare form of plasma cell malignancy that presents as a single mass of monoclonal plasma cells located either intraosseous or extramedullary (extraosseous). Extramedullary plasmacytoma can affect any part of the body, but the most common sites of origin are the head and neck region. The involvement of pleura is very rare. Here, we are enlightening this rare presentation and making readers aware of the clinical presentation and management of this rare malignancy.
RESUMEN
Mechanical prosthetic valves, like all foreign bodies, are thrombogenic, requiring anticoagulation to avoid thrombosis and reduce the risk of catastrophic stroke. We reported a case of a 42-year-old female that developed mechanical valve thrombosis and was successfully treated with low infusion thrombolytic therapy using alteplase (tPA, tissue plasminogen activator).
RESUMEN
Chilaiditi sign is a rare radiological finding in which the colon is interposed between the liver and the abdominal wall. Once patients become symptomatic, the condition is called Chilaiditi syndrome. We discuss a unique patient who presented with intermittent abdominal pain for 2 years that worsened 6 months before presentation. Her radiological evaluation revealed Chilaiditi sign. She was treated conservatively and the sign resolved. We emphasize the importance of conservative management in Chilaiditi syndrome.
RESUMEN
Primary spinal epidural non-Hodgkin's lymphoma (PSENHL) is a tumor of central nervous system origin. It is one of the rarest tumors seen in the fourth to fifth decades of life. The majority of PSENHLs are diffuse large B-cell lymphomas and are most commonly caused because of chronic inflammatory process, chronic infection, or autoimmune disease. Here, we are presenting a case of a 51-year-old male who was found to have a diffuse large B-cell lymphoma, specifically germinal center B-cell type that is considered a rare presentation.
RESUMEN
BACKGROUND: Ewing sarcoma (ES), the second most common malignant bone tumor after osteosarcoma in the second decade, occurs in 0.9% of cases as the primary non-sacral form. CASE: A 20-years-old male presented with acute paraparesis of bilateral lower limb and numbness following initial back pain for the last 6 months. Magnetic resonance imaging (MRI) of the lumbar spine revealed a 4 cm enhancing soft tissue mass at the L4/L5 vertebra extending into the spinal canal with compression of the thecal sac. The computed tomography (CT) of the chest, abdomen, and pelvis revealed aggressive lytic lesions in the L4 spinous process with soft tissue extension into the spinal canal with no other site of distant metastasis. He was treated with IV steroids (Injection dexamethasone 10 mg IV followed by 4 mg tablet dexamethasone q6h; subsequently tapered off). A core needle biopsy showed a small, round blue cell neoplasm, (suggestive of a primitive neuroectodermal) stained positive for CD99 and vimentin stain. The diagnosis of ES lumbar spine was made which was treated with surgical resection with an appropriate margin measuring 8 × 4.5 × 2.5 cm with decompression and L4/5 laminectomies, which had a negative margin in the surgical pathology report. Concomitant local radiotherapy and chemotherapy [cycles of vincristine 2 mg/m2 , adriamycin/doxorubicin 75 mg/m2 , cyclophosphamide 1200 mg/m2 (VDC) with mesna rescue alternating with cycles of ifosfamide 1800 mg/m2 and etoposide 100 mg/m2 (IE)] was started. The motor strength was regained gradually with preserved spine biomechanics and oncological control with no recurrence in 2-year follow-ups. CONCLUSIONS: The presentation of lumbar ES can vary from local pain and swelling to acute paraparesis. Timely diagnosis and treatment with multimodal therapy, namely, steroids for acute spinal cord compression and surgery with chemoradiotherapy for ES can improve spinal biomechanics and oncological control.

INTRODUCTION: Inherent differences as well as health disparities among rural and urban populations warrant further studies focused on the characteristics and outcomes in COVID-19 patients in a rural setting. The aim of this study was to describe these elements in patients infected with SARS-CoV2, hospitalized at a single center in rural Pennsylvania. METHODS: Patients with SARS-CoV2 infections hospitalized between March-December 2020 were studied. Data were obtained from electronic health records generated reports and was retrospectively analyzed. Patients were classified into three groups according to severity. Distribution of variables was studied among these three groups. Using certain variables, we ran logistic regression analysis to study the odds of death and requirement of mechanical ventilation (MV). RESULTS: Among 335 hospitalized patients infected with SARS-CoV2, age more than 65 years increased the severity of clinical status and in-hospital mortality. Gender did not affect odds of death nor need for MV. Hypertension was the most common comorbidity, but diabetes mellitus and chronic obstructive pulmonary disease (COPD) increased the risk of death. In terms of laboratory parameters, our data suggests that maximum LDH marginally increased the risk of death and maximum WBC marginally increased the risk of need for MV and death. CONCLUSION: Through our basic analysis of various characteristics of SARS-CoV2 positive patients admitted in a rural hospital, we have identified certain risk factors associated with severe disease and increased in-hospital mortality. These were found to be largely similar to current literature from studies in urban populations, bolstering the reproducibility and generalizability of existing knowledge. This information lays the foundation for future studies to investigate the role of these factors in morbidity and mortality associated with COVID-19 in depth.

Adrenal cortical carcinoma is a rare and aggressive cancer with poor prognosis. Cases usually present with signs and symptoms of excessive hormone production. Hyperglycemia and Cushing syndrome are common, but tumor-associated hypoglycemia due to paraneoplastic secretion of insulin-like growth factor-2 (termed Anderson's syndrome) is uncommon. Given the rarity of adrenal cortical carcinoma, diagnosis and management of associated complications is challenging. In this study, we present a case of metastatic adrenal cortical carcinoma with a myriad of hormonal abnormalities. We will also briefly review literature regarding genetic association, pathophysiology, treatment options, and prognosis.

Background Biliary dyskinesia is a functional gallbladder disorder in which there is an absence of a structural or mechanical cause for biliary pain. A cholecystokinin-hepatobiliary iminodiacetic acid (CCK-HIDA) scan is typically performed during workup, and cholecystectomy is the accepted treatment for low ejection fraction (EF) (less than 33%, as defined by the literature). However, few studies have examined the role of cholecystectomy in hyperkinetic gallbladder (EF ≥80%). The aim of our study was to examine symptom resolution following minimally invasive cholecystectomy in patients with hyperkinetic gallbladder. Methodology A retrospective chart review was conducted at Robert Packer Hospital in Sayre, PA. Patients who underwent minimally invasive cholecystectomy for biliary colic with EF ≥80% and who were without cholelithiasis on preoperative imaging or on final pathology were included in this study. The main outcome was symptom resolution at the postoperative visit. Data collected included age, gender, EF, body mass index, symptoms with CCK infusion, and pathology. Results A total of 48 patients were included. The mean age of patients was 41.2 years (standard deviation = 14.4), and the median age of patients was 42.2 years, with a range of 17-71 years. The majority of patients were female (83.3%). Overall, 58.3% of patients had replication of symptoms with CCK infusion. The mean gallbladder EF was 87.3%, with a median of 87.0 and a range of 80-98. In total, 33 (68.8%) patients had chronic cholecystitis on final pathology reports. There was a 95.9% symptom resolution rate among our patients two weeks postoperatively. Conclusions The overwhelming majority of patients experienced symptom resolution prior to their two-week postoperative visit following minimally invasive cholecystectomy for hyperkinetic gallbladder. These results strongly suggest a role of surgical management in patients with high EF.
RESUMEN
Primary central nervous system lymphoma (PCNSL) is a rare form of CNS tumor. Immunosuppression is the most important risk factor of PCNSL, but few immunocompetent individuals are also affected. The most common clinical feature of PCNSL includes dizziness and ataxia. Our patient was a 71-year-old immunocompetent female who presented with progressive ataxia, imbalance, and dizziness for one year. A homogenous enhancing lesion was found in magnetic resonance imaging (MRI) of the head. One month later, on a follow-up MRI, a significant increase in the tumor size with surrounding edema was seen. The patient underwent craniotomy and resection of the mass. Subsequently, a diagnosis of diffuse large B cell lymphoma was made on pathology examination. Guideline-directed treatment options were discussed. This case highlights that the prognosis of patients with PCNSL highly depends on the factors such as age and physical status. Early diagnosis by accurate interpretation of imaging and management is crucial for better health outcomes.
RESUMEN
Coronavirus disease (COVID-19) is a global health crisis leading to increased morbidity and mortality worldwide. It is associated with increased activation of the clotting system leading to thrombotic complications increasing the risk of life-threatening complications. We report a case of a 70-years-old COVID-19 positive patient who presented with both lower extremities and forearm pain. On workup, she was found to have an extensive arterial clot. In patients with COVID-19, arterial clots may be the initial presenting symptoms to the hospital and can be fatal if not brought to attention on time.
RESUMEN
Medulloblastoma (MB) is an aggressive malignant tumor of the posterior fossa of the CNS that mainly affects children younger than 15 years of age. It is uncommon in the adult population compared to children. Any adult patient presenting with cerebellar mass must be evaluated with brain tissue biopsy to rule out MB. Our patient is a 27-year-old female who presented with sudden onset of frontal headache and was diagnosed with MB.
RESUMEN
Extranodal mucosa-associated lymphoid tissue (MALT) is a type of non-Hodgkin's lymphoma (NHL). It commonly involves the GI tract, but the involvement of the urinary bladder is very rare. It comprises less than 1% of bladder tumors and 0.2% of extranodal lymphomas. Fewer than a hundred cases are reported so far and limited literature is available on the management. Here we are presenting a gentleman with MALT lymphoma of the urinary bladder who presented with urinary frequency, an urgency which was initially managed as benign prosthetic hyperplasia. Initially, the treatment helped him with improvement in his symptoms. After a recurrence of his symptoms 11 years later, he underwent cystoscopy with biopsy that revealed MALT lymphoma of the bladder and underwent radiotherapy.
RESUMEN
BACKGROUND: Syncope has many aetiologies but from a cardiac standpoint, if arrhythmogenic and ischaemic causes are not present, obstructive lesions should be considered. Cardiac spindle cell sarcomas are incredibly rare and difficult to cure. CASE SUMMARY: A 62-year-old man presented for exercise stress test and had a syncopal episode on the treadmill. He was found to have a massive mass obstructing the transmitral flow. Patient was taken to the operating room and the mass was resected successfully. Histopathological confirmation revealed the mass to be a cardiac intimal sarcoma. Patient was initiated on a trial regimen of doxorubin, ifosfamide, and mesna. DISCUSSION: Cardiac intimal sarcomas are aggressive cancers and are difficult to treat; there are no established treatment guidelines. They can lead to obstruction of blood flow through the cardiac chambers. From a cardiac perspective, without arrhythmogenic and ischaemic causes of syncope, obstructive lesions should be considered.
RESUMEN
Gallbladder (GB) carcinoma is a rare carcinoma with a poor prognosis. The prevalence is 0.7-21/100,000 worldwide and 1-2/100,000 in the United States. Adenosquamous cell carcinoma is composed of glandular and squamous components. The overall five-year survival rate is less than 5%, with a median survival of fewer than six months. We are presenting a case of adenosquamous carcinoma of the GB in a 76-year-old female who presented with right upper quadrant abdominal pain and was found to have an enlarged GB, with thickened irregular wall likely inflammatory or malignant and mildly dilated common bile duct on ultrasound imaging of the abdomen. Core needle biopsy of GB showed findings compatible with adenosquamous carcinoma and immunohistochemistry was positive for P40, CK5,6. She was diagnosed with stage T4 N0 M0. She was started on chemotherapy with cisplatin and gemcitabine (25 mg/m2 and 1000 mg/m2), respectively, every three weeks but her condition worsened after the fifth cycle of chemotherapy and she decided to move forward with hospice care given her bad prognosis. Unfortunately, she passed away one week after being discharged home.
