• Vaccination uptake among post-treatment cancer survivors: A multi-vaccine scoping review. Vaccine Renduchintala, K., Arevalo, M., Fonseca, G., Haver, M. K., Gwede, C. K., Pabbathi, S., Christy, S. M. 2024; 42 (22): 125995

  Abstract

  Our goal was to provide an overview of uptake rates across vaccine types and factors associated with vaccine uptake among cancer survivor populations.A literature search was conducted using Ovid MEDLINE® ALL (Wolters Kluwer), Embase (Elsevier) and CINAHL Complete (EBSCO) databases and according to PRISMA guidelines. Eligible articles were limited to those examining vaccination uptake among cancer survivors who had completed treatment, reported factors associated with uptake (e.g., barriers and facilitators), and published in English between 2011 and 2021. Two independent reviewers screened citations for inclusion and two performed data abstraction, verified by an arbiter.The search returned 4,215 total articles, and 271 duplicates were removed. During abstract/title screening, 212 articles were identified. Following full-text screening, 47 articles/abstracts were found to meet inclusion criteria, 16 articles/abstracts were removed, and 31 studies were included in the review. Among the 31 studies, participant age ranged from 9 years to adults of all ages. Vaccine types included: influenza (n = 18), human papillomavirus (n = 10), pneumococcal (n = 8), hepatitis A/B (n = 1), shingles (n = 1), measles (n = 1), tetanus/diphtheria (n = 1), and haemophilus influenza B (n = 1). Vaccine uptake varied greatly across studies, vaccine types, and participant populations. Factors affecting vaccination uptake included sociodemographic variables and social determinants of health, health beliefs/attitudes/knowledge, provider recommendation, and cancer treatment/clinical variables.Our findings highlight the need for further examining factors associated with vaccine uptake, the need for clinical guidelines that specifically address vaccination among cancer survivors, and potential targets for multi-level interventions to improve vaccination rates among cancer survivor populations.

• Schwannomas Mimicking Leptomeningeal Spread in the Setting of Breast Cancer: A Case Report. In vivo (Athens, Greece) Jalali, S., Renduchintala, K., Afiat, T. P., Pabbathi, S. 2023; 37 (6): 2835-2839

  Abstract

  Breast cancer is currently the most diagnosed cancer globally. For patients who complete breast cancer treatment, developing a survivorship plan is important, including serial history, physical examinations, and annual mammograms to look for recurrence and metastasis.This is a case report of a 76-year-old female with a history of recurrent breast cancer who presented with lower-back pain and found to have MRI findings initially concerning for intradural extramedullary metastatic disease. Biopsy was later found to be consistent with benign spinal schwannomas.We present a unique case of spinal masses in the setting of breast cancer initially concerning for leptomeningeal spread, later found to have benign schwannomas that mimicked leptomeningeal spread on imaging. To our knowledge, this is the first reported case of schwannomas mimicking leptomeningeal spread in a patient with a history of recurrent breast cancer. After metastasis is excluded, schwannomas should be considered in the differential of benign spinal lesions.

• The Implementation and Assessment of a Perioperative Co-Management of Surgical Services Rotation for Medical Students. Journal of surgical education Renduchintala, K., Liu, Y. W., Vo, K., Wang, M. 2022; 79 (5): 1099-1102

  Abstract

  To develop a hospital-based perioperative surgical co-management curriculum rotation to provide educational value to fourth year medical students, many of whom are future surgical trainees. We leveraged our Hospitalist service which comanages patients with many surgical subspecialties to teach students about preoperative optimization, postoperative management of both acute medical issues and chronic comorbidities, and the interprofessional team for surgical care.Medical students were assigned to surgical co-management services on two to four week rotations. In addition to inpatient rounds with a multidisciplinary team, students were taught through a case-based didactic curriculum and weekly journal clubs.Keck Hospital of University of Southern California, Los Angeles, California PARTICIPANTS: Forty-three fourth year medical students RESULTS: Seventeen fourth year medical students in the 2018-2019 academic year and 26 fourth year medical students in the 2019-2020 academic year completed our rotation. The students rated the rotation 4.88 out of 5 in the 2018-2019 academic year and 4.73 out of 5 in the 2019-2020 academic year in developing their confidence, knowledge, and clinical skills.A structured course on perioperative co-management for medical students is a valuable learning experience and can be implemented at other medical schools. For surgical trainees, this course provides a unique perspective on their own prospective fields, working in the role of their future Hospitalist partners.

• Successful Treatment of Community-Acquired Methicillin-Resistant Staphylococcus Aureus Necrotizing Pneumonia in the Setting of Chronic Graft-Versus-Host Disease. Cureus Renduchintala, K., Nanjappa, S., Ramsakal, A., Greene, J. 2021; 13 (2): e13123

  Abstract

  Necrotizing pneumonia (NP) is a rare complication of community-acquired pneumonia that results in tissue necrosis and permanent destruction of the lung parenchyma. This study presents a case of a 21-year old male patient with T-cell acute lymphoblastic lymphoma who was treated with chemotherapy and matched-unrelated donor stem cell transplantation. His post-transplant course included chronic graft-versus-host disease (GVHD) and subsequent community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) necrotizing pneumonia. In addition to antibiotics, steroids were used to help blunt the proinflammatory response following CA-MRSA pneumonia and this led to a rapid improvement in our patient's clinical course. CA-MRSA pneumonia is often treated with vancomycin. Given the nature of necrotizing pneumonia, the use of a toxin reducing agent like linezolid and adjunct therapy with corticosteroids was beneficial in the management of this disease process in our patient with chronic GVHD. Further prospective studies are needed to evaluate this regimen as a therapeutic alternative.

• A Case of Alpha-1 Antitrypsin Deficiency and Organizing Pneumonia. Cureus Renduchintala, K., Pabbathi, S., Nanjappa, S., Ramsakal, A., Greene, J. 2020; 12 (12): e12078

  Abstract

  Alpha-1 antitrypsin deficiency (AATD) is an autosomal dominant genetic disorder that presents with pulmonary complications and is most commonly manifested by panacinar emphysema and chronic obstructive pulmonary disease. A 49-year-old Caucasian female with a history of AATD and chronic tobacco use was referred to both infectious disease and thoracic surgery clinics with worsening cough and chronic intermittent hemoptysis for the evaluation of possible superimposed infection or malignancy. She had previously been treated with multiple antibiotics and Prolastin-CÒ (alpha-1-proteinase inhibitor). Initial CT of the chest showed known chronic bronchiectasis, severe lower lung emphysema, and right-sided lower lobe pulmonary masses. CT-guided biopsy of one mass showed nonspecific inflammation, negative cultures, and negative cytology. Subsequent follow-up with chest CT scans showed a decreasing size of right-sided pulmonary masses and new left-sided nodule formation, which later stabilized in growth. Based on symptoms and radiological and pathological findings, a diagnosis of organizing pneumonia was made. We present an unusual case of bilateral pulmonary masses mimicking infection and malignancy later found to be most consistent with an organizing pneumonia in a patient with underlying AATD.

• Tear cathepsin S as a candidate biomarker for Sjögren's syndrome. Arthritis & rheumatology (Hoboken, N.J.) Hamm-Alvarez, S. F., Janga, S. R., Edman, M. C., Madrigal, S., Shah, M., Frousiakis, S. E., Renduchintala, K., Zhu, J., Bricel, S., Silka, K., Bach, D., Heur, M., Christianakis, S., Arkfeld, D. G., Irvine, J., Mack, W. J., Stohl, W. 2014; 66 (7): 1872-81

  Abstract

  The diagnosis of Sjögren's syndrome (SS) in routine practice is largely a clinical one and requires a high index of suspicion by the treating physician. This great dependence on clinical judgment frequently leads to delayed diagnosis or misdiagnosis. Tear protein profiles have been proposed as simple and reliable biomarkers for the diagnosis of SS. Given that cathepsin S activity is increased in the lacrimal glands and tears of NOD mice (a murine model of SS), the aim of this study was to explore the clinical utility of using tear cathepsin S (CTSS) activity as a biomarker for SS.A method to measure CTSS activity in tears eluted from Schirmer's test strips was developed and validated. Schirmer's tests were performed and CTSS activity measurements were obtained in 278 female subjects, including 73 with SS, 79 with rheumatoid arthritis, 40 with systemic lupus erythematosus, 10 with blepharitis, 31 with nonspecific dry eye disease, and 12 with other autoimmune diseases, as well as 33 healthy control subjects.The median tear CTSS activity in patients with SS was 4.1-fold higher than that in patients with other autoimmune diseases, 2.1-fold higher than that in patients with nonspecific dry eye disease, and 41.1-fold higher than that in healthy control subjects. Tear CTSS levels were equally elevated in patients with primary SS and those with secondary SS, independent of the Schirmer's test strip values or the levels of circulating anti-SSA or anti-SSB antibodies.Markedly high levels of tear CTSS activity are suggestive of SS. CTSS activity in tears can be measured in a simple, quick, economical, and noninvasive manner and may serve as a novel biomarker for autoimmune dacryoadenitis during the diagnostic evaluation for SS.
