Diabetic Pneumopathy- A Novel Diabetes-associated Complication: Pathophysiology, the Underlying Mechanism and Combination Medication.

BACKGROUND: The "diabetic lung" has been identified as a possible target organ in diabetes, with abnormalities in ventilation control, bronchomotor tone, lung volume, pulmonary diffusing capacity, and neuroadrenergic bronchial innervation. OBJECTIVE: This review summarizes studies related to diabetic pneumopathy, pathophysiology and a number of pulmonary disorders including type 1 and type 2 diabetes. METHODOLOGY: Electronic searches were conducted on databases such as Pub Med, Wiley Online Library (WOL), Scopus, Elsevier, ScienceDirect, and Google Scholar using standard keywords "diabetes," "diabetes Pneumopathy," "Pathophysiology," "Lung diseases," "lung infection" for review articles published between 1978 to 2023 very few previous review articles based their focus on diabetic pneumopathy and its pathophysiology. RESULTS: Globally, the incidence of diabetes mellitus has been rising. It is a chronic, progressive metabolic disease. The "diabetic lung" may serve as a model of accelerated ageing since diabetics' rate of respiratory function deterioration is two to three-times higher than that of normal, non-smoking people. CONCLUSION: Diabetes-induced pulmonary dysfunction has not gained the attention it deserves due to a lack of proven causality and changes in cellular properties. The mechanism underlying a particular lung illness can still only be partially activated by diabetes but there is evidence that hyperglycemia is linked to pulmonary fibrosis in diabetic people.

Immunotherapy in extensive small cell lung cancer.

Small cell lung cancer which constitutes about 15% of lung cancers is pathobiologically and clinically distinct from non small cell cancer. Histologically it is characterized by small cells with scant cytoplasm, absent or inconspicuous nucleoli, extensive necrosis, and expresses neuroendocrine markers. It is on a spectrum of neuroendocrine cancer that extend from typical carcinoids to large cell to small cell cancer. Clinically it behaves in a more malignant fashion with a rapid doubling time, early metastasis. They respond rapidly to cytotoxic treatment however tend to develop resistance soon. Immunotherapy with checkpoint inhibitors take advantage of PD 1 ligand-receptor axis between the tumor and T cells or CTLA4 on T cells which when engaged lead to inhibition of T cells. This inhibition helps tumors to evade immune surveillance. Checkpoint inhibitors break this axis by either binding to PD 1 ligands or PD 1 to CTLA4, thereby preventing tumors to evade the immune systems. This has led to remarkable responses in tumors. The immune related adverse effects can be severe however are experienced at much lower rates as compared to cytotoxic chemotherapy. Recently, CheckMate 032 has shown impressive response rates with Nivolumab and Nivolumab/Ipilimumab in relapsed small cell cancer. IMpower 133, a phase 3 trial showed that addition of Atezolizumab to Carbo/Etoposide led to a significant survival benefit in treatment naive extensive small cell cancer. This review will summarize recent developments and ongoing studies of immune therapy in extensive small cell cancer in addition to a brief summary of immune therapy landscape of Non small cell lung cancer. Investigational approaches to immune therapy have also been delineated.

Chalazia Development in Multiple Myeloma: A New Complication Associated with Bortezomib Therapy.

Multiple myeloma (MM) is a neoplasm of plasma cells within the bone marrow. A major impact on improving survival in MM has been the use of the boronic acid-derived proteasome inhibitor bortezomib, a first-in-class selective inhibitor of the 26S proteasome. Ocular side effects of bortezomib are rare. In this report, we present 2 patients with active MM in whom persistent chalazia became a therapy-interfering complication of treatment with bortezomib. Both patients had relapsed ISS III B kappa light chain myeloma, and they were responding to treatment with bortezomib until chalazia - which caused intolerable discomfort - started. In both patients discontinuation of bortezomib was necessary for chalazia to heal, and restarting of bortezomib was associated with relapse of chalazia.

Lung Cancer Screening for the Poor and Underserved: Should Routine Screening be Performed?

BACKGROUND: Lung cancer is a leading cause of death in United States. A recent study using low dose CT scans for screening long term smokers for lung cancer has, for the first time, demonstrated reduction in mortality, although it is not a standard of care in the community yet. METHOD: We analyzed lung cancer data for stages 0 through 4 for 1,412 individuals from, a public hospital, Nassau University Medical Center (NUMC) with patients of lower income, two private hospitals, North Shore University Hospital (NSUH) and Long Island Jewish Hospital (LIJ), with patients of higher income, with average household income per year of 83,795 $, 152,777 $ and 93,234 $ respectively. RESULT: Significantly smaller percentages of patients were diagnosed with stages 0 and 1 lung cancer at NUMC (8.55%) versus either NSUH (36.18%, P < 0.001) or LIJ (35.70%, (P < 0.001). CONCLUSION: At this point there is evidence that Lung Cancer Screening reduces mortality in long term smokers, but there is debate over, if it should be made into a recommendation. In light of the above study we suggest, that screening for lower socioeconomic class, could be recommended, if not for general population.

Lymphocyte Rich Hodgkin's Lymphoma Presented with Warm Hemolytic Anemia: A Case Report and Literature Review.

Hodgkin's lymphoma accounts for ten percent of all lymphomas. In the United States, there are about 8000 new cases every year. This paper describes a case of lymphocyte-rich Hodgkin's lymphoma (LRHL) manifested by autoimmune hemolytic anemia (AIHA). A 27-year-old Israeli male presented with dizziness associated with one month of low-grade fevers and night sweats; he also complained of persistent cough, pruritus, and ten-pound weight lost during this time. The CBC revealed hemoglobin of 5.9 gm/dL, and direct Coomb's test detected multiple nonspecific antibodies consistent with the diagnosis of AIHA. Chest, abdomen, and pelvic CT scan showed mediastinal lymphadenopathy and splenomegaly. Lymph node biopsy revealed classic LRHL. AIHA resolved after completion of the first cycle of chemotherapy with adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD); after six cycles, he went into complete remission. Although infrequent, AIHA can be responsible for the presenting symptoms of HL.
