Implications of Corona Virus Disease-19 pandemic on cytopathology laboratory-Challenges and solutions in resource-limited settings.

Background: Corona Virus Disease-19 (COVID-19) disease which is still showing peaks and plateau with emerging new mutational viral variants has led to the modification of working of hospitals and medical institutes. Cytopathology laboratories geared up with the changing situation to cope up with not only the COVID-19 patients but also patients of other diseases, particularly oncology patients. It was also important to adopt changes in the cytopathology residency program so as to cope up with the changing scenario. Aim: The present study was conducted to study the various measures adopted and the changes made in the cytopathology laboratory during COVID-19 infection in a resource-limited setting while catering to a large population of COVID-19-positive patients in the north Himalayan region of India. It was also intended to study the methods adopted for effective cytopathology residency training during corona times. Setting and Design: The study was conducted from March 2020 to December 2021 in the cytopathology lab, and all the samples were analyzed and compared with the samples received in pre-corona times from March 2018 to December 2019. The different methods adopted during corona times for effective cytopathology residency training were also analyzed. Results: The total number of samples received in the cytopathology laboratory in pre-corona times from March 2018 to December 2019 were 6822, and samples received from March 2020 to December 2021 were 6567 with decrease of 1.9% of cases. There was increase in 17.4% for the samples of the respiratory tract received in the lab with an increase in cases of infections including aspergillosis, mucormycosis, and tuberculosis. There was 10.3% increase in cytological diagnosis of malignant cases during corona times. Use of 90% alcohol for fixation rather than air drying of smears, avoiding of pneumatic tubes, judicious use of personal protective equipment (PPE) kits along with access to the digital cytology slide database were included in the changes made in the lab. Conclusions: There was a marginal decrease in cytopathological diagnosis during COVID-19 with substantial increase in the malignancy rate of 10.3% in cytological diagnosis of different organs. Diagnosis of mucormycosis, aspergillosis, and tuberculosis infections of respiratory tract cytology increased during this period. Judicious use of limited available resources led not only to smooth functioning of the cytopathology lab but also prevented any infection in the working health personals. Newer online resources were explored and modified for continuous training of the cytopathology residents. Emotional support with effective communication was the key to alleviate any psychological stress among all health professionals in the cytopathology laboratory.

A rare report of H-partially deficient, non-secretor phenotype from India. An Ah like the rèunion and unlike a Para Bombay-Clarifying misinterpretations.

BACKGROUND: H-deficient phenotypes are classified as H-deficient non- secretors (Bombay Oh), H-deficient secretors (Para Bombay), and H-partially deficient non-secretors (O h reunion, Ah and Bh, ABh). REPORT: We report the first case of H-partially deficient non-secretor- the Ah phenotype from India. What makes this report interesting is that they do not fit into the Bombay, or the Para Bombay series of H-deficient phenotypes and these partially deficient non-secretors were exclusively found on Réunion Island, off the East Coast of Africa in 1982. These reunion type phenotypes have not been reported since then and may lead to misinterpretations and confusions when encountered in the current existing laboratory settings especially in the low income (LIC's) and low middle income (LMIC's) countries like our own. Moreover, literature from LMIC and LIC incorrectly uses Ah/Bh for parabombay phenotypes. CONCLUSIONS: H-deficient phenotypes are rare, challenging to identify and assign correct notations. Hence, we have highlighted characteristic differences between H-deficient phenotypes and illustrated a diagnostic laboratory approach to correctly identify and assign notations to them especially in the resource constrained settings.

Analytical and Post Analytical Phase of an ISO 15189:2012 Certified Cytopathology Laboratory-A Five Year Institutional Experience.

Objective: Analytical and post analytical phase are integral part of total quality management system and include steps from submission of slides till reports are dispatched. The present study was conducted to analyze the analytical and post analytical phase of the ISO15189:2012 certified cytopathology laboratory. It was also intended to study the various errors which were encountered and steps taken to reduce these discrepancies. Methods: The study included all documents of quality program from 1 November 2014 till 31 Oct 2019 in medical institute situated in north Himalayan region of India. All the data was recorded and analyzed for analytical and post analytical phase. Results: The number of samples received in cytopathology lab was 21,566 with total quality errors of 5.19%. Out of these pre-analytical errors were 55%, analytical 10.5% and post analytical errors constituted 34.4%. The maximum errors detected were due to typographical errors followed by delayed turnaround time. Cyto-histopathological discordance was 10.5% in non-gynecological cases and 2.2% in gynecological cases. Conclusion: Analytical and post analytical phase analysis is essential to minimize the errors and improve the quality of cytopathology lab. Cyto-histopathological correlation is valuable for continuous data tracking in the cytopathology with analytical errors analysis. Maintenance of external, internal quality program, turnaround time with documentation, continuous training and communication with clinician is fundamental for quality improvement in any cytopathology lab. Acknowledgement of nonconformance with root cause analysis and sincere efforts to minimize them is the basic key for successful quality management.

Effect of autologous PRP on wound healing in dental regenerative surgeries and its correlation with PDGF levels.

INTRODUCTION: Autologous platelet-rich plasma (PRP) is the fraction of blood plasma, with increased concentration of platelets, from baseline serum level. Growth factors (GFs) in PRP expedite the soft tissue and bony healing. However, estimation of their levels and role in healing had not been studied extensively. This study gives an insight to the quantification of platelet-derived GF-BB (PDGF-BB) present in PRP and its correlation with the clinical wound healing and bone regeneration. AIMS: This study aims to quantify PDGF-BB levels in PRP with its subsequent correlation with healing in dental regenerative surgeries. SETTINGS AND DESIGN: This was an experimental study including patients undergoing various dental regenerative surgeries. SUBJECTS AND METHODS: Autologous thrombin-activated PRP in the form of PRP gel was used in study group (n = 39) whereas no such intervention was given in control group (n = 30). PDGF-BB quantification was done in PRP samples using enzyme-linked immunosorbent assay. Clinicoradiological evaluation of healing was done in both the groups. STATISTICAL ANALYSIS USED: Descriptive analysis, independent Z-test, Correlation regression analysis, and ANOVA. RESULTS: Mean platelet concentration achieved in PRP was 5.79 times the baseline count. Mean PDGF-BB concentration in PRP was 31.92 ± 10.47 ng/ml which significantly correlated (P < 0.05) with the PRP platelet count. Study group showed significant healing clinically (P < 0.05). Significant bone fill observed in study group at 3 and 6 months when compared to the baseline as well as control group. Furthermore, bone fill at 6 months showed linear correlation with PGDF-BB levels (r = 0. 80). CONCLUSIONS: PRP led to enhanced bone regeneration and soft-tissue healing with former being directly related to higher concentration of PDGF-BB.

Human immunodeficiency virus/acquired immune deficiency syndrome: A survey on the knowledge, attitude, and practice among medical professionals at a tertiary health-care institution in Uttarakhand, India.

INTRODUCTION: Health-care professionals are trained health-care providers who occupy a potential vanguard position in human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) prevention programs and the management of AIDS patients. This study was performed to assess HIV/AIDS-related knowledge, attitude, and practice (KAP) and perceptions among health-care professionals at a tertiary health-care institution in Uttarakhand, India, and to identify the target group where more education on HIV is needed. MATERIALS AND METHODS: A cross-sectional KAP survey was conducted among five groups comprising consultants, residents, medical students, laboratory technicians, and nurses. Probability proportional to size sampling was used for generating random samples. Data analysis was performed using charts and tables in Microsoft Excel 2016, and statistical analysis was performed using the Statistical Package for the Social Science software version 20.0. RESULTS: Most participants had incomplete knowledge regarding the various aspects of HIV/AIDS. Attitude in all the study groups was receptive toward people living with HIV/AIDS. Practical application of knowledge was best observed in the clinicians as well as medical students. Poor performance by technicians and nurses was observed in prevention and prophylaxis. All groups were well informed about the National AIDS Control Policy except technicians. CONCLUSION: Poor knowledge about HIV infection, particularly among the young medical students and paramedics, is evidence of the lacunae in the teaching system, which must be kept in mind while formulating teaching programs. As suggested by the respondents, Information Education Communication activities should be improvised making use of print, electronic, and social media along with interactive awareness sessions, regular continuing medical educations, and seminars to ensure good quality of safe modern medical care.

Blood transfusion safety: A study of adverse reactions at the blood bank of a tertiary care center.

BACKGROUND: An adverse transfusion reaction (ATR) is an unfavorable reaction to the transfused unit, the severity of which may be different among individuals depending upon the type of reaction and the patient's susceptibility. Transfusion reactions may be immediate or delayed type depending on the onset and immune or nonimmune type depending on the pathogenesis. A study was conducted to study the frequency of various transfusion reactions and the associated morbidity. MATERIALS AND METHODS: All ATRs occurring over a period of 3 years at a tertiary care health center were studied in detail according to the institute's protocol. RESULTS: Of 38,013 units of blood and components that had been issued, 101 (0.2%) cases had an ATR. The most common reaction was allergic - 34/101 (33.6%) followed by febrile - 26/101 (25.7%). Other reactions included transfusion-related acute lung injury in 6/101 (5.9%) cases, and immune reactions were seen in 19/101 (18.8%) cases. CONCLUSION: Allergic and febrile reactions are most common and least harmful, but fatal reactions can also occur, and preventive measures must be taken to avoid such reactions.

Trends of transfusion transmissible diseases among blood donors at uttarakhand, India.

CONTEXT: Blood can save lives; however, it can be a source of transfusion transmitted diseases if proper screening of donated blood is not done. It is now mandatory to screen all donated blood units, whether replacement or voluntary for five transfusion transmitted diseases-namely human immunodeficiency virus (HIV), hepatitis B and C, syphilis, and malaria. AIMS: The present study was done to study the prevalence of infectious disease markers among donors at the blood bank of a tertiary care center. SETTINGS AND DESIGN: A total of 53,069 donors donated blood over 11 years. The number of replacement and voluntary donors was 41,710 and 11,359, respectively. MATERIALS AND METHODS: Screening of blood units was done by enzyme-linked immunosorbent assay (ELISA) method for HIV and hepatitis B and C. HIV testing was done using fourth generation ELISA kits. Syphilis was tested by latex agglutination assay and malaria was tested using slide method up to the year 2008-2009 and by rapid immunochromatographic assay after that. RESULTS: The mean percentage of these infections per year was found to be 0.2, 1.2, 0.9, 0.3, and 0.002% for HIV, hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV), syphilis, and malarial parasite (MP), respectively. CONCLUSIONS: The risk of transfusion transmissible infection (TTI) today is low but supply of safe blood depends on proper donor selection and sensitive screening tests.

Hematological parameters in patients of cleft lip and cleft palate with special reference to eosinophil counts.

INTRODUCTION: Birth abnormalities like cleft lip and cleft palate account for about 1.4 per 1000 live births in India. These are seen to be associated with a high incidence of eosinophilia which delays the surgical management of these patients. AIMS: The aim of this paper is to study the hematological parameters in patients of cleft lip and cleft palate. PATIENTS AND METHODS: A total of 223 cases of cleft lip and cleft palate were taken up for the study. Hematological parameters including hemoglobin, total leukocyte count, differential leukocyte count, absolute eosinophil count, and red cell indices were studied. RESULTS: Anemia was found in 182/223 (81.63%) cases which was most commonly of microcytic hypochromic type. Eosinophilia was seen in 46/223 (20.60%) cases. CONCLUSIONS: Many cleft lip and cleft palate patients show high eosinophil counts. Absolute eosinophil count was found to be a better parameter for assessment of eosinophils.

Male genitourinary tuberculosis--13 years experience at a tertiary care center in India.

We conducted a retrospective study of genitourinary tuberculosis (TB) among males attending a hospital in the northern Himalayan region of India. Records from 1 January 1997 to 31 December 2009 were reviewed for clinical history, relevant radiological findings laboratory data, histopathology and treatment. Of the 1,113 male urogenital non-neoplastic specimens received at the histopathology laboratory of the hospital, tuberculosis was diagnosed in 25 cases (2.2%). Urinary bladder and prostate were the most common organs involved. Thirty-six percent of cases had a previous history of TB; 12% of cases presented with no symptoms. Ziehl-Neelsen staining was positive in 72% of cases. Cultures were positive for TB in 42.8% of cases and polymerase chain reaction was positive in two cases in which it was performed. Antituberculosis treatment was required for up to 12 months in some cases and surgery was required in 32% of cases. Genitourinary TB in this study had varying presentations. Cases having strong clinical and radiological findings and suggestive histopathology for tuberculosis, even without demonstration of mycobacteria may be considered for TB treatment, particularly in endemic areas. Patients living in more remote areas may have more specific and severe symptoms due to late presentation. Histopathology plays a crucial role in diagnosis due to lack of sophisticated techniques. The emphasis should be on early detection followed by prompt treatment to avoid further complications.

Alcohol intake and cigarette smoking: impact of two major lifestyle factors on male fertility.

CONTEXT: Lifestyle factors, like alcohol intake and cigarette smoking, have been reported to affect male fertility. AIMS: To find out the specific impact of alcohol and smoking on semen quality of male partners of couples seeking treatment for primary infertility. MATERIALS AND METHODS: From the semen samples analyzed in our andrology laboratory, results of 100 alcoholics and 100 cigarette smoker males were studied following WHO guidelines and compared with 100 strict nonalcoholic and nonsmoker males for presence of asthenozoospermia, oligozoospermia and teratozoospermia. STATISTICAL ANALYSIS: Data was analyzed by F- test using Microsoft Office Excel 2003. RESULTS: Only 12% alcoholics and six per cent smokers showed normozoospermia compared to 37 % nonalcoholic nonsmoker males. Teratozoospermia, followed by oligozoospermia dominated alcoholics. Overall impact of asthenozoospermia and teratozoospermia, but not of oligozoospermia, was observed in smokers. Light smokers predominantly showed asthenozoospermia. Heavy alcoholics and smokers showed asthenozoospermia, teratozoospermia as well as oligozoospermia. CONCLUSIONS: Asthenozoospermia, the most common semen variable in our study, can be an early indicator of reduction in quality of semen. Alcohol abuse apparently targets sperm morphology and sperm production. Smoke-induced toxins primarily hamper sperm motility and seminal fluid quality. Progressive deterioration in semen quality is related to increasing quantity of alcohol intake and cigarettes smoked.

Utilization of blood and components in a tertiary care hospital.

PURPOSE: Blood transfusion is an important part of patient management. Indications for blood use must be clear in the mind of ordering clinicians, to avoid its misuse and also to avoid unnecessary exposure of the patient to donor blood antigens, adverse reactions and transfusion transmissible diseases. METHODS: In a retrospective pilot study, details of whole blood and components transfused were noted and correlated with the patient's diagnosis and indications for transfusion, during 1 month. RESULTS: The blood units supplied were 720. Whole blood was the most utilized product; followed by packed red blood cells. Supply of blood was maximum to the surgical wards. The patients of trauma followed by malignancy and surgery required whole blood mostly. Anemia was the most common indication for blood products. CONCLUSIONS: Periodic review of blood component usage is very important to assess the blood utilization pattern in any hospital.

Hematological malignancies diagnosed by bone marrow examination in a tertiary hospital at Uttarakhand, India.

INTRODUCTION: Hematological malignancies are quite common and affect all ages and genders. The diagnosis involves a multiparameter approach. The geographical distribution of various types of hematological malignancies has been provided by various authors but no such data have been published regarding the State of Uttarakhand in India. AIM: To study the hematological malignancies at Uttarakhand in India based on age, sex and the type of malignancy with further sub typing wherever possible. SETTINGS AND DESIGN: A total of 220 cases of hematological malignancies were worked up from the Reference Laboratory of Himalayan Institute of Medical Sciences over an eight year period (1998-2005). MATERIALS AND METHODS: Diagnosis was mainly based on morphological examination of peripheral blood and bone marrow smears stained by Leishman's stain and MPO, Sudan Black and PAS stain as and where required. Distribution of cases was studied based on age, sex and the type of malignancy with further sub typing wherever possible. RESULTS: The most common hematological malignancy was found to be Leukemia 129/220 (58%) followed b Lymphoma 33/220 (14.8%), Multiple Myeloma 55/220 (24.7%) and Metastatic Lesions 3/220 (1.3%). These malignancies were seen to be distributed throughout all ages with a peak at 11-20 years age group 39/220 (17.5%) and another peak at 51-60 years age group 41/220 (18.4%). We found an overall male preponderance with a M:F ratio of 2.3:1. CONCLUSIONS: The commonest haematological malignancy in our series was Leukemia. Other diagnoses were Multiple Myeloma, Lymphoma and Secondaries. Multiple Myeloma which turned out to be the second most common diagnosis was an unusual finding.

Pattern of cancers amongst patients attending Himalayan Institute of Medical Sciences, Dehradun.

This hospital-based study seeks to find out the most common cancers amongst the patients attending Himalayan Institute of Medical Sciences (HIMS), Dehradun, situated in Uttaranchal, which has inadequate health care facilities and low socio-economical status. In our study, of the 20,247 cases reported in the pathology department from July 1996 to Dec. 2003, 18.57% cases were malignant. Male to female ratio was 1.7:1.Top five cancers in males were those of lung, larynx, non-Hodgkins lymphoma, oesophagus & stomach. Top five cancers in females were those of breast, cervix, gall bladder, ovary & oesophagus. Tobacco and alcohol related cancers predominated in males. Skin and soft tissue cancers and were also common amongst both genders. Patients mostly reported with cancers in advanced stages, which could be attributed to poor medical facilities and health awareness in this region.
