ABSTRACT
Introduction: Oral cancers are the most serious health issues in underdeveloped countries such as India and considered as the main cause of death. Among them, oral squamous cell carcinoma is the most common type (90%) of all malignancies. Various oral potential malignant lesions (OPMLs) can transform into malignancies. This study was conducted to determine the significance of Ki‑67 expression in oral potential malignant and malignant lesions (MLs) as well as correlation of mitotic index (MI) with MIB‑1 labeling index (LI) in these lesions. MaterialsandMethods: The study was performed on 60 cases in a tertiary care center over a period of 2 years. Ki‑67 expression, MI and MIB‑1 LI were calculated and correlated. Results: In the studied population, there were 49 (81.7%) males and 11 (18.3%) females. The mean age was 46.60 ± 9.94 (23–68 years), with majority of patients in 41–60 years of age group (46/60 cases). Anterior 2/3rd tongue is the most affected site, presented ulcer as the most common lesion. Smoking, tobacco, and betel nutchewing addiction were presented in 72% of the patients. Among 60 cases, 45 (75%) were OPMLs, while 15 (25%) cases were MLs. MI increases in OPMLs and MLs and comparison was significant (P < 0.01). MIB‑1 LI was significant (P < 0.01) on comparison to dysplasia III and MLs. A positive correlation (0.01) was established between MI and MIB‑1 LI of OPMLs and MLs. Conclusion: Ki‑67 expression was found correlated with the progression of disease from OPMLs to MLs. Therefore, it is considered a proliferative marker that corresponds with disease progression. Both proliferative indices (MI and MIB‑1 LI) are positively correlated
ABSTRACT
Background: COVID‑19 virus, causing severe acute respiratory illness (SARS‑CoV‑2), was declared as a pandemic by the WHO in March 2020, after its first outbreak in China at the end of 2019. The major purpose is to establish the role of a hematological and inflammatory markers in early diagnosis of COVID‑19 illness and its relationship with the disease severity. Materials and Methods: The study was performed in a tertiary care center from April to September 2020. The study included 150 hospitalized COVID‑19 Reverse transcription‑polymerase chain reaction positive patients. According to ICMR standards, research patients were grouped into mild, moderate, and severe categories depending on clinical evaluation. Different laboratory parameters complete blood counts, prothrombin time (PT), activated partial thromboplastin time (APTT), d‑dimer, serum ferritin, C‑reactive protein (CRP), and mean results are compared among the patient in three disease severity groups. Results: In the studied population, there were 106 (70.7%) males and 44 (29.3%) females. The average age of the research participants was 48.40 ± 11.50 (21–75 years), with majority of patients being old (>60 years). Hematological markers such as total leukocyte count, Neutrophil‑to‑lymphocyte ratio (NLR), and platelet lymphocyte ratio (PLR) and the levels of PT, APTT, and D‑dimer, as well as ferritin and CRP, all were considerably high with different groups of disease severity (P = 0.001). Conclusion: The study concluded that patients of severe disease category have significantly higher levels of leukocytosis, neutrophilia, elevated NLR, PLR, PT, APTT, D‑dimer, serum ferritin, and CRP. Hematological and coagulation symptoms are associated with COVID‑19 illness, and these indicators might be employed as a prognosticator for prediction of early disease severity.
ABSTRACT
Background: Psoriasis is a multifactorial chronic relapsing inflammatory dermatological disorder associated with significant comorbidities. It is characterized by sharply demarcated, erythematous papules, and plaques with abundant silvery-white scales. Due to its variable clinical presentation, histopathology remains the mainstay of diagnosis. However, these histologic features changes with treatment and may also guide in therapeutic decision-making. Aim: The aim is to evaluate and compare the histopathological features of psoriatic lesions before treatment with those receiving treatment for psoriasis. Patients and Methods: A total of 101 biopsies from selected consecutive patients of histopathologically confirmed psoriasis vulgaris were included in the study. These cases were then divided into two groups, Group A includes cases who never received treatment and Group B, those receiving treatment for psoriasis. These biopsies were histopathologically analyzed and compared for various morphological features. Results: Of 101 cases of psoriasis, 72 cases were included in Group A and 29 were included in Group B. Biopsies of Group A showed parakeratosis and acanthosis as a common feature in all of them with dilated or abnormal capillary pattern in dermal papillae in 93.1%. In Group B, in spite of uniform parakeratosis as noticed in Group A biopsies, focal parakeratosis was seen in 83.3%, acanthosis in 87.5%, and dilated/abnormal capillary pattern in dermis was observed to be a universal feature in biopsies of Group B. All other microscopic features of psoriasis also decreased in frequency in Group B. However, statistically significant difference is seen only in changes in morphological features of superficial epidermis that is, parakeratosis, acanthosis, and absent or decreased granular layer in both the groups. Conclusion: Treatment may lead to improvement in the histologic features in epidermis with significant difference in few of them. However, abnormal vasculature in the dermal papillae persists and does not show any improvement with therapy.
ABSTRACT
Background: Palpable breast lumps are quite common which can be benign or malignant. Carcinoma breast is the second most common cancer after cervical cancer. Fine needle aspiration cytology (FNAC) is a minimally invasive, rapid, reliable and cost-effective outdoor procedure to provide effective diagnosis and way to further planning of treatment without need for biopsy. The objective of the study is to study the spectrum of various breast lesions on cytomorphology and its histopathological correlation. Methods: This was a two years retrospective study from June 2014 to May 2016 including 280 cases aspirated from palpable breast lumps. Physical examination of breast lumps by palpation was done. Cytological diagnosis was made and histopathological correlation was done, wherever available. Results: On cytomorphological study of 280 breast lump aspirates 32 (11.43%) were inflammatory lesions, 180 (64.29%) benign, 6 (2.14%) atypical/probably benign, 8 (2.86%) suspicious of malignancy, 46 (16.43%) malignant and 8 (2.86%) were unsatisfactory for evaluation, of these 280 cases, 70 (25%) were available for histopathological examination. The most common benign lesion in the present study was fibroadenoma 115 (41.07%) and the most common malignant lesion was ductal carcinoma 43 (15.36%). Conclusion: Fine needle aspiration cytology is a rapid and reliable tool to provide effective diagnosis in palpable breast lumps. It should be used as routine diagnostic procedure to provide the effective health care to the patients with breast lesions.
ABSTRACT
Background: Blood transfusion has profound role to play in specific illness, but still due to unsafe and careless practices the peril of transfusion transmissible infections (TTIs) such as human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), syphilis and malaria prevails. Objective: To study the seroprevalence of TTIs in healthy blood donors in specific Kuppuswamy’s socio-economic scale at a Blood Bank of a tertiary care teaching hospital in north India, to enhance the awareness about transfusion related risks and to implement better strategic measures to prevent TTI, in high risk groups. Material and Method: Total 10,569 blood units were collected from Jan-2014 to Septmeber-2015. All donors were categorised according to the Kuppuswamy’s Socioeconomic Status Scale (KSESS) followed by screening of all sera samples for hepatitis B surface antigen (HBsAg), antibodies to HCV, HIV types 1 and 2 using enzyme-linked immunosorbent assays (ELISA) and for malaria antigen and Treponema pallidum by using immunochromatographic tests and Rapid Plasma Reagin test (RPR) respectively. All the samples found reactive for HIV, HBsAg, and HCV were again confirmed by second ELISA. Results: The overall seroprevalence was HCV 2.06 % (218/10569) > HBV 1.71% (181/10569) > HIV 0.03% (3/10569). No donor was found positive for Malaria and VDRL. The prevalence of transfusion transmissible diseases in specific socio economic class was as follows-:Upper lower class (IV) 248/2261 (10.96%) > Lower class (V) 34/483 (7.03%) > Lower Middle class (III) 97/5789 (1.67%) > Upper middle class (II) 22/1552 (1.42%) > Upper class (I) 1/484 (0.20%) and seroprevalence of transfusion transmissible diseases in each socio economic class, out of total donations was as follows-: Upper lower class (IV) 248/10569 (2.35%)> Lower middle class (III) 97/10569 (0.92%) >Lower class (V) 34/10569 (0.32%)> upper middle class (II) 22/10569 (0.21) >Upper class (I) 1/10569 (0.009%). Conclusion: Maximum positive TTIs had association with low socio-economic status people with increased medical and behavioral risk factors. Hence, we conclude that awareness among the high risk population group, strict and skillfulness selection of donors and use of effective laboratory screening tests is the prerequisite for the safe donation!!
