- Abstract
In India economy, foreign commerce is significant. The covid-19 epidemic has severely hurt international trade. India exports as it is now already had a decline in the previous year, but slowly and surely, it is achieving solid growth on a global scale. As a result, an effort has been undertaken to research India commerce during the COVID-19 period after noticing this trend. Additionally, data from earlier years have been used to compare the expansion and contraction of the industry. The patterns that India had previously experienced are included in this report. Multiple secondary data sources had linked to this study, which shows that COVID-19 had a significant negative influence on India foreign commerce and caused it to contract frequently throughout that time.

General Engineering - Abstract
The COVID-19 pandemic resulted in substantial morbidity and mortality across the world. The prognosis was found to be poor in patients with co-morbidities such as diabetes, hypertension, interstitial lung disease, etc. Although biochemical studies were done in patient samples, no study has been reported from the Indian subcontinent about ultrastructural changes in the vital organs of COVID-19 patients. The present study was, therefore, conducted to understand the ultrastructural changes in the lung, liver, and brain of the deceased patients.The present study was conducted on samples obtained from reverse transcription-polymerase chain reaction (RT-PCR)-positive patients who were admitted to a tertiary care hospital in Western India. Core needle biopsies were done in eight fatal cases of COVID-19. The samples were taken from the lungs, liver, and brain and subjected to light microscopy, immunohistochemistry (IHC), and transmission electron microscopy (TEM). Clinical details and biochemical findings were also collected. Results: The study participants included seven males and one female. The presenting complaints included fever, breathlessness, and cough. Light microscopy revealed diffuse alveolar damage in the lungs. Further, a positive expression of SARS-CoV-2 nucleocapsid protein was observed in the pulmonary parenchyma of five patients. Also, the TEM microphotograph showed viral particles of size up to 80nm localized in alveolar epithelial cells. However, no viral particles were found in liver or brain samples. In the liver, macrovesicular steatosis and centrizonal congestion with loss of hepatocytes were observed in light microscopy. This is the first study in the Indian population showing the

General Medicine ,General Biochemistry, Genetics and Molecular Biology - Abstract
Paroxysmal nocturnal haemoglobinuria is a rare acquired disease characterized by bone marrow failure, intravascular haemolysis and thrombophilia. Thrombosis is the deadliest complication of paroxysmal nocturnal haemoglobinuria (PNH). The present study was conducted to study the prevalence of PNH in cases of deep vein thrombosis (DVT) which was previously undocumented from western Rajasthan.In the present cross-sectional study, 61 adult patients with DVT were tested using flow cytometry to detect PNH clones. Blood samples were processed using fluorescein-labelled proaerolysin, CD14, CD24, CD33 and CD45 panels for granulocytes and monocytes and CD59 and CD235a panel for red blood cells.Three cases (4.92%) having large clones on monocytes as well as granulocytes, which fulfilled the diagnostic criteria of PNH were detected. Further, three cases (4.92%) showed small clones on both granulocytes and monocytes. Nine (15%) cases showed small clones only on granulocytes, and 11 (18%) cases showed small clones only on monocytes.The results of the present study suggest that a higher proportion of patients had PNH in western Rajasthan compared to previously reported studies from elsewhere. It is suggested that PNH testing should be added to the procoagulant work-up panel in institutions of this region where it is not routinely done. This provides an otherwise missed opportunity to diagnose this disorder. Eculizumab may be employed, which is effective in reducing thrombophilic events in cases of PNH.

The 2019 novel coronavirus (2019-nCoV) originated in Wuhan City of China. In India, first confirmed case of coronavirus disease (COVID-19) was reported on January 30, 2020 and India is presently hit by second wave of COVID-19. The aim of the present study was to evaluate bone marrow findings of COVID-19 by minimally invasive autopsies to aid in understanding pathophysiology of the disease. This prospective study was conducted at tertiary care centre of Western Rajasthan. After obtaining approval from Institute's ethics committee and consent from next of kins, minimally invasive autopsies were conducted in 37 COVID-19 deceased patients within an hour after the death. The tissue specimens were processed with standard biosafety measures. Electronic medical records were reviewed retrospectively and patients' clinical details and results of laboratory investigations were noted. In this prospective study, bone marrow biopsies were collected from 37 COVID-19 minimally invasive autopsies. Mean age of these cases was 61.8 years and male: female ratio was 2.36. Comorbidities were observed in 25 (67.5%) of all cases. Histopathological analysis revealed hypercellular, normocellular and hypocellular marrow in 5, 25 and 5 cases respectively (two biopsies were inadequate). There was marked interstitial prominence of histiocytes in 24 (68.5%) cases. Out of these, evidence of haemophagocytosis was observed in 14 (40%) cases, marked increase of haemosiderin laden macrophages in 20 (57.1%) cases. There was prominence of plasma cells in 28 (80%) cases. The present study attempted to fill the gap of dearth of literature from our country in COVID-19 autopsy studies by highlighting bone marrow findings. The data support the evidence of development of secondary haemophagocytic lymphocytosis in COVID-19 cases.

Background: COVID-19 pandemic has taken a great toll on the health care system worldwide. Along with the pandemic, there is also a concern regarding post COVID-19 complications in recovered patients. Thromboembolism (TE) has been reported as a fatal complication in recovered patients with COVID-19. There is still a great dilemma in post-discharge TE prophylaxis and its long-term benefits. Case Description: We reported three cases of post COVID-19 with complications related to both diseases as well as post discharge anticoagulant therapy. The first case is about a 60-yr-old male who developed Covid-19 pneumonia (moderate disease) and was discharged on rivaroxaban after initial improvement. 3 weeks later, the patient was readmitted with lower gastro-intestinal bleeding. The other two cases developed pulmonary thromboembolism within a span of 2-3 months (after recovered from COVID-19 pneumonia). Both these patients were not prescribed anticoagulants for TE prophylaxis. Conclusion: There is an imperative need for effective guidelines for post discharge TE prophylaxis in COVID-19.

Objectives The 2019 novel coronavirus (2019-nCoV) has spread across the globe with more than 6 lakh deaths. Clinical autopsies are important to understand the pathobiology of the disease. Materials and Methods Autopsy techniques have been modified to be minimally invasive autopsies in all COVID-19 positive cases, and tissue biopsies were sampled from lungs, liver, and bone marrow within an hour after death. Detailed histological analysis was performed in the sampled tissues, along with immunohistochemistry. Patients’ clinical records were collected. Statistical Analysis Descriptive statistics were used to summarize data. Results Of the 21 cases studied, 76.2% patients were ≥ 60 years of age, 80.9% were males, and 85.7% had co-morbidities. Histopathological analysis revealed diffuse alveolar damage (including exudative and organizing phase) in 88.9% cases. Microthrombi were seen in 44.4% cases. Additional findings include viral cytopathic changes, metaplastic change in the epithelium, intra-alveolar hemorrhage, and pulmonary edema. Liver showed centrizonal congestion with hepatocytic loss, lobular inflammation, steatosis, Kupffer cell hypertrophy, and sinusoidal neutrophilic infiltration, while significant portal infiltrate and cholestasis were absent to minimal. Bone marrow revealed hemophagocytosis in 60% cases. Conclusion Incorporation of minimally invasive autopsies provides an effective method to study the pathological findings in COVID-19 deaths in resource-constrained settings. Presence of pulmonary microthrombi in a significant number of cases supports the vascular events, apart from the characteristic diffuse alveolar damage, as an important pathogenic mechanism for lung injury in COVID-19 infections. Histopathological findings in the liver and bone marrow suggest indirect insult to these organs, related to circulatory and/or hyperinflammatory response to viral infections.

Background The effect of individuals oral disease patterns on the family has been too little explored. Despite awareness of the importance of the family unit for personal health and health care system, the family unit has been infrequently studied from the public health point of view. Objective The specific aim of the study was to evaluate children's oral health as predictors of family functioning and to validate psychometric properties of Hindi version of family impact scale among 12-15-year-olds. Material and methods A total of 225 parent-child pair participated in the study. A cross-cultural translation, adaptation and validation of Hindi version of family impact scale (FIS) was conducted. Test-retest reliability was assessed by the intraclass correlation coefficients (ICC) using a two-way mixed-effect model. Discriminant validity was verified by family impact scores among parent-child pair with and without oral diseases. Construct validity was corroborated by association between the scale scores with global indicators of oral health and overall well-being. Clinical examinations were conducted using modified WHO criteria (1997). Influence of independent variables on the FIS were assessed using regression analysis. Results Mean impact score was 25.16 ± 5.96 with almost non-existent floor effect (4%) and no ceiling effect in the population. Inter Class Correlation for FIS scale was 0.86 indicating perfect agreement. Parents of children with dental caries and poor oral hygiene reported higher overall FIS scores (p Conclusions This study provides evidence that oral disorders have a significant impact on family functioning. The Hindi version of the FIS exhibited good psychometric properties, with acceptable validity and reliability. Future research needs to explore the consequences of higher family impact scores and focus on strategies to reduce the impacts of oral conditions on the family.

β-Thalassaemia, the most common monogenic disorder, is characterized by genetic heterogeneity at the molecular level. More than 300 mutations of the β globin gene have been characterized all over the world, however, few common mutations account for majority of the cases in various populations. The present study aimed to screen known cases of β-thalassaemia in the Western part of Rajasthan state for five common mutations. The study included 144 known cases of β-thalassaemia of all clinical phenotypes. Cases were diagnosed based on clinical features, haematology investigations including haemogram and Hb-HPLC. Blood samples from cases were taken for mutation analysis. After DNA extraction, mutations were characterized by the polymerase chain reaction method employing allele specific priming technique (AMRS) to study the five mutations including IVS-I-5 (G → C), IVS-I-1 (G → T), CD41/42 (–TCTT), CD 8/9 (+G) and 619 bp deletion from the 3′ end of the β-globin gene using a total of seven different primers. Of all 144 cases, 74 (51.38% of all) cases were of β-thalassaemia major, five (3.4% of all) cases were of β-thalassaemia intermedia and 65 (45.14% of all) cases were of β-thalassaemia minor. Mutation analysis revealed that five common mutations were present in 130 (90.27% of all) cases. Among identified mutations, highest frequency of mutation was of IVS-I-5 (G → C) identified in 73 cases (50.7% of all cases). In 11 (7.63% of all) cases, more than one mutation was identified. β-Thalassaemias are common in Western Rajasthan; however, there is dearth of literature from this part of the country. We observed that five common mutations are common in this part of the country also. These observations are helping us in forming the basis for comprehensive diagnostic database that would not only be useful for genetic counselling but also for prenatal diagnosis.

Nutritional deficiency is associated with weaken immune system and increased susceptibility to infection. Among other nutrients, several trace elements have been shown to regulate immune responses. Iron is one of the most abundant trace elements present in our body, which is required in various biological processes. Iron has an immunomodulatory function and thus influence the susceptibility to the course and outcome of a variety of viral infections. So, this present study was aimed to study relations of different iron-related biomarkers in association to severity and mortality in SARS-CoV-2 patients.A total of 150 individuals infected with COVID-19 and 50 healthy individuals were recruited. Cases were divided based on severity (mild, moderate, and severe) and outcome (discharged or deceased). Serum iron, TIBC, ferritin, transferrin, transferrin saturation levels were analyzed by the direct colourimetric method.In cases the median levels of serum iron, TIBC, transferrin, transferrin saturation and ferritin are 29 µg/dL, 132.53 µg/dL, 106.3 mg/dL, 17.74 % and 702.9 ng/dL respectively. Similarly, in controls the median levels of serum iron, TIBC, transferrin, transferrin saturation and ferritin are 53 µg/dL, 391.88 µg/dL, 313.51 mg/dL, 12.81 % and 13.52 ng/dL respectively. On comparing the cases with the controls, a significant lower level of iron, TIBC, and transferrin were found in the cases along with the significant higher levels of ferritin and transferrin saturation. On comparing the Receiver operating characteristic (ROC) curves of Iron, Ferritin, Transferrin, Transferrin sat % and TIBC in relation to survival in COVID-19 patients it was found that iron, followed by transferrin and ferritin has the highest area under the curve (AUC) with 74 %, 63 % and 61 % respectively. Further, in pairwise analysis of ROC curve, a significant difference was found between the Iron-transferrin (p 0.01), iron-TIBC (p 0.001) and transferrin-ferritin (P 0.01). The multiple regression model based on Iron and transferrin outperformed any other combination of variables via stepwise AIC selection with an AUC of 98.2 %. The cutoff point according to Youden's J index is characterized with a sensitivity of 98 % and a specificity of 96.8 %, indicating that iron along with transferrin can be a useful marker that may contribute to a better assessment of survival chances in COVID-19.Our study demonstrated a significantly decreased levels of iron, TIBC,transferrin and a significantly increased levels of ferritin and transferrin saturation in COVID-19 patients when compared with controls. Further, Iron and transferrin were observed to be a good predictor of mortality in patients with COVID-19. From the above analysis we confirm that iron-related biomarkers play an important role in the development of oxidative stress and further lead to activation of the cytokine storm. So, continuous monitoring of these parameters could be helpful in the early detection of individuals developing the severe disease and can be used to decrease mortality in upcoming new waves of COVID-19.

Progressive disseminated histoplasmosis (PDH) usually presents as fever, anemia, leukopenia, hepatosplenomegaly, lymphadenopathy and pulmonary symptoms. There are few reports showed the association of Idiopathic CD4 lymphocytopenia (ICL) with histoplasmosis. We describe a 65-year-old female presented with history of fever, papulo-nodular rash and significant weight loss and diagnosed as progressive disseminated histoplasmosis. All immunocompromised conditions were ruled out. In addition, her 2 consecutive CD4 counts were below 300. The patient was diagnosed with PDH associated with ICL. Patient showed significant improvement with liposomal amphotericin B and itraconazole. Absolute CD4 counts should be done in all cases of progressive disseminated histoplasmosis even in HIV negative individuals to rule out associated ICL.

Background:: The understanding of pathogenesis is necessary for the development of effective treatment for COVID-19. Various studies have postulated that there is a complex interplay of mediators of coagulation and inflammation responsible for the pathogenesis of COVID-19. We did this study on coagulation parameters and inflammatory markers and their effect on outcome in patients with COVID-19. Methods: This was a single centre observational cross-sectional study. Procoagulants [Prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, lupus anticoagulant (LA), fibrinogen, factor-VIII (F-VIII)]; anticoagulants [protein-C (PC), protein-S (PS), antithrombin] and inflammatory markers [interleukin-6 (IL-6) and highly sensitive – C-reactive protein (hs-CRP)] were measured at the time of hospitalization and correlated with the severity of the disease. Results: A total of 230 patients were enrolled, of which 61.3%, 20.0%, and 18.7% had asymptomatic/ mild, moderate, or severe disease, respectively. COVID-19 disease severity was associated with rising trends with coagulation parameters (PT, APTT, D-Dimer; p value 0.01, Conclusions: This study revealed increased levels of coagulation and inflammatory parameters, which correlated with the severity of COVID-19. Age, D-dimer, IL-6, hs-CRP, APTT, fibrinogen, and Factor VIII were significantly higher in patients with moderate and severe disease as compared to asymptomatic/mild disease. Advanced age, high D-dimer, and high hs-CRP were significantly associated with poor outcomes.

The use of aromatherapy for the reduction of anxiety levels during dental treatment procedures has been well established in the literature; however, there is limited evidence regarding its efficacy. The present meta-analysis is an attempt to assess the association between the use of aromatherapy and anxiety levels among dental patients. A comprehensive search was conducted across Medline, Scopus, Web of Science, EBSCO host, Cochrane databases, and Google Scholar for studies evaluating aromatherapy and anxiety level among dental patients. PRISMA guidelines were followed for the meta-analysis. Randomized and cluster-randomized trials comparing aromatherapy with controls were included. The random-effects model was used to assess the mean differences in anxiety levels of patients visiting dental OPD. The significance value was set at P < 0.05. Six studies were identified that met the requirements for inclusion. Aromatherapy was significantly associated with reduction in patient anxiety levels during dental treatment (pooled mean difference: -3.36 [95% CI, -3.77 - -2.95, P = 0.00001). Low heterogeneity was noted between studies (I2 = 1%, P = 0.41) analyzed in the meta-analysis. High certainty of the evidence was obtained from the association between the use of aromatherapy and dental anxiety. This meta-analysis suggests that aromatherapy is effective in reducing dental anxiety. When used judiciously, the results of this work should encourage the use of aromatherapy to reduce patient anxiety levels during dental procedures.

Chronic myeloid leukemia (CML) is predominantly a disease of adults and the elderly. CML is uncommon in the paediatric age. Priapism as an initial presentation is quite uncommon in CML and is rare in the case of CML in paediatric and adolescent age. We present a case of CML in an adolescent male who presented with priapism of 48 hours duration. The patient was managed in an emergency by corporal aspiration and saline irrigation and was found to have CML during a hospital stay. The patient was treated with imatinib and is under follow-up for the last two years.

Integration of genetic information into our understanding of oral diseases has fostered the hope to intervene the disease process among genetically susceptible individuals. Oral submucous fibrosis (OSF) (mainly in the Southeast Asia region) and tobacco smoking are two of the major public health problems the world is facing today. With more and more diseases being associated with alleles of the human leukocyte antigen (HLA), the objective of the study was to explore any genetic association of OSF and smoking behaviour with specific HLA Class II DQB1*0503 and HLA DRB1*0301 alleles.Genomic DNA was extracted from saliva of 64 patients divided into an OSF group, a tobacco smokers group and a control group. This was followed by polymerase chain reaction (PCR) with sequence-specific primer of HLA-DQB1*0503 and HLA DRB1*0301 allele, visualised under 2% agarose gel.A statistically significant difference was observed between the OSF group and controls in presence of HLA-DQB1*0503 allele, with 84% of the patients showing the presence. Frequency of HLA DRB1*0301 allele was also found to be significantly higher (72%) among OSF patients (p0.001). Similar results were shown in tobacco smokers with 28% cases showing presence of HLA DRB1*0301 allele and 13 (52%) of them having DQB1*0503 allele (p0.001).HLA-DRB1*0301 and HLA-DQB1*0503 are statistically significantly associated with susceptibility to OSF and smoking behaviour.

Aims: To determine the factors influencing awareness about beta-thalassemia in the population. Settings and Design: A cross sectional study was conducted by the Department of Pathology, AIIMS, Jodhpur. Methods and Material: The study population included participants with medical as well as non-medical background, to ensure representation of all sections of the society. Data was collected in an objective survey form drafted in simple language. Statistical Analysis Used: The data was analysed using Microsoft Excel and Chi Square Test for Independence was performed. Results: The participants with a positive family history had significantly more knowledge compared to others, but even these participants didn't have complete knowledge about the disease. Age and gender had no significant impact on the results. The mode of occurrence of beta-thalassemia was known to less than half of the participants, with even less number being aware of the fact that diagnosis of beta-thalassemia can be made before birth. Participants with a medical background were aware that there were several forms of beta-thalassemia, but the knowledge about treatment options was limited. Conclusions: Various factors affect the awareness in the general population, which has an effect on the outcome of screening programmes. There is a need for successful implementation of a screening programme for beta-thalassemia in order to reduce the financial burden that it imposes on healthcare facilities and to lessen the emotional burden on relatives of patients with the disease.

Antiphospholipid syndrome (APS), an autoantibody mediated disease, is characterized by presence of antibodies against the proteins bound to the phospholipid membranes. The antibodies are predominantly formed against beta-2-glycoprotein I (b2GPI) which is considered pathogenic, but presence of lupus anticoagulant is a predictor of thrombotic events. The thrombotic events in APS may manifest as venous or arterial or small vessel thrombosis in any tissue or organ and pregnancy related complications namely, recurrent (three or more) and early spontaneous miscarriages before 10 weeks of gestation or unexplained deaths of normal fetus at or beyond 10 weeks, eclampsia or severe pre-eclampsia, intra-uterine growth retardation and pre-term births. However, lately its role as an etiological mechanism in causation of certain neuro-psychiatric disorders has been put forth. It has been suggested that one should suspect APS in psychiatric manifestations which are atypical, resistant to treatment, associated with cognitive decline and dementia, abnormal involuntary movements, livedo reticularis, migraine, thrombotic events like stroke or transient ischemic attacks, obstetrical complications. In this brief communication, we describe the case of young male who has been suffering from treatment resistant and difficult to manage bipolar affective disorder (BPAD) with fluctuating thrombocytopenia and neurological findings with positive lupus anticoagulant. We propose it to be a consequence of an atypical presentation of APS.

Objective Using video-EEG (v-EEG) diagnosis as a gold standard, we assessed the predictive diagnostic value of home videos of spells with or without additional limited demographic data in US veterans referred for evaluation of epilepsy. Veterans, in particular, stand to benefit from improved diagnostic tools given higher rates of PNES and limited accessibility to care. Methods This was a prospective, blinded diagnostic accuracy study in adults conducted at the Houston VA Medical Center from 12/2015–06/2019. Patients with a definitive diagnosis of epileptic seizures (ES), psychogenic nonepileptic seizures (PNES), or physiologic nonepileptic events (PhysNEE) from v-EEG monitoring were asked to submit home videos. Four board-certified epileptologists blinded to the original diagnosis formulated a diagnostic impression based upon the home video review alone and video plus limited demographic data. Results Fifty patients (30 males; mean age 47.7 years) submitted home videos. Of these, 14 had ES, 33 had PNES, and three had PhysNEE diagnosed by v-EEG. The diagnostic accuracy by video alone was 88.0%, with a sensitivity of 83.9% and specificity of 89.6%. Providing raters with basic patient demographic information in addition to the home videos did not significantly improve diagnostic accuracy when comparing to reviewing the videos alone. Inter-rater agreement between four raters based on video was moderate with both videos alone (kappa = 0.59) and video plus limited demographic data (kappa = 0.60). Significance This study demonstrated that home videos of paroxysmal events could be an important tool in reliably diagnosing ES vs. PNES in veterans referred for evaluation of epilepsy when interpreted by experts. A moderate inter-rater reliability was observed in this study.

Bone marrow microenvironment plays a crucial role in the growth of hemopoietic cells and bone marrow function, which in turn depends on an intact microvasculature. Our study assesses the microvessel density (MVD) in the bone marrow of aplastic anemia (AA) patients, compares with MVD of controls and MVD among the different types of AA. Bone marrow specimens from 60 patients with AA and 17 controls were studied. There were 33 patients with non severe AA (NSAA), 12 patients with severe AA (SAA) and 15 patients with very severe AA (VSAA). MVD was calculated on sections stained immunohistochemically for CD34. The mean bone marrow MVD in AA group was 1.28 ± 0.36, being significantly lower than that in control group (6.80 ± 1.59, p

Brucellosis is a common zoonotic disease worldwide. It has protean clinical manifestation and sometimes may has a life-threatening complication. A 4-year-old boy presented with a history of fever, myalgia and appetite loss for 3 weeks. On examination, he had hepatosplenomegaly. The initial working diagnosis was an infection, autoimmune disease and malignancy. Investigations showed positive Brucella serology, and he was started on rifampicin and cotrimoxazole. He was further investigated because of persistent fever, which revealed evidence of haemophagocytic lymphohistiocytosis (HLH). He continued treatment for brucellosis, except rifampicin which was replaced with doxycyclin due to a worsening liver function. The child showed complete clinical and biochemical improvement after 6 weeks of therapy. HLH is a life-threatening condition and should be suspected in children with brucellosis, who did not respond to appropriate antibiotics treatment. Secondary HLH does not always require specific therapy; it may improve with adequate treatment of the underlying condition.

Recurrent hemarthrosis is a common entity in children. Although recurrent hemarthrosis most often associated with hemophilia (VIII or IX deficiency), but rarely it can be associated with factor VII deficiency (FVIID). It is a strong mimicker of hemophilic hemarthrosis. Once hemophilia is excluded as a cause of recurrent hemarthrosis, congenital FVIID needs to be considered for long-term planning of treatment and avoiding unnecessary transfusion of factor concentrates. Clinical presentation of FVIID has a varied spectrum and does not correlate with factor levels. Here, we present a case of recurrent hemarthrosis secondary to FVIID.

Background: Neonatal jaundice is the most commonly observed clinical condition of early neonatal period. It remains a common cause of readmission and important cause of concern for the parents and clinicians. Therefore, appropriate management of neonatal hyperbilirubinemia is of paramount importance. Phototherapy plays a significant role in its management but this modality is not devoid of complications. Authors studied electrolyte changes in the neonates, who received phototherapy.Methods: This perspective hospital based observational study conducted over the period of one year on 90 eligible admitted neonates who received phototherapy as per AAP guideline. Serum bilirubin, sodium, potassium and calcium were determined before and after termination of phototherapy. The first samples were considered as controls and compared with the samples collected after termination of phototherapy.Results: The incidence of LBW babies in this study was 21.9%, while mean birth weight and gestational age was2.76±0.38 kg and 38.34±0.88 weeks respectively. Mean duration of phototherapy was 38.48±09.34 hours. The mean sodium, potassium and calcium level before therapy were 146.6±6.2 mg/dl, 4.7±0.47 mg/dl and 9.4±0.73 mg/dl respectively. Authors found statistically significant changes in the electrolyte’s levels (Na+ 141.3±6.1, K+ 4.2±0.51 and Ca+2 8.4±0.68 respectively), after phototherapy however none of any neonate shown any clinical signs of dyselectolytemia.Conclusions: Neonates undergoing phototherapy are at greater risk of dyselectrolytemia especially in preterm babies therefore close clinical and biochemical monitoring is required for the prompt management of any significant electrolyte imbalance.

Objectives Myeloperoxidase (MPO) detection either by enzyme cytochemistry (cMPO) or flow cytometry (fMPO) plays a major role in acute leukaemia (AL) diagnosis as per World Health Organization (WHO) 2008 classification. Although 3% cMPO was recommended as positivity, no specific cut-off had been mentioned by WHO for fMPO. Various authors recommend different cut-offs ranging from 3 to 28% for fMPO. The aim of this study was to analyse fMPO cut-offs ranging from 3 to 10% in classifying AL and to assess whether a new cut-off could be suggested. Methods Totally, 216 cases of AL were retrospectively analysed for fMPO ranging from 3 to 10% and compared with gold standard. Presence of cMPO (≥3%) and/or expression of two or more pan-myeloid markers (CD13, CD33, and CD117) in the absence of CD19 and CD3 were kept as gold standard for diagnosis of acute myeloid leukaemia (AML). Results Sensitivities for classifying AL as AML/mixed phenotypic acute leukaemia (MPAL) at 3, 5.4, and 10% were 98.3, 98.3, and 96.6%, respectively, whereas specificities at this cut-off were 22.2, 91, and 71%, respectively. Discussion Only few studies have been done in this aspect to define a consistent cut-off for fMPO for proper classification of acute leukaemias. This was one of the largest and few studies available till date in this regard. Conclusion The newer cut-off for fMPO (5.4%) emerged out from our study with best sensitivity and specificity for accurately classifying AL cases into acute lymphoblastic leukaemia, AML, and MPAL.

Aplastic anemia (AA) is a life-threatening bone marrow failure disorder, if untreated, is associated with very high mortality. Allogenic bone marrow transplantation (BMT) is the standard of care for severe aplastic anemia (SAA) patients those who are younger than 40 years of age. The development of secondary malignancies in post-BMT setting for AA is a rare, however, well documented phenomenon. Among the secondary malignancies, development of acute myeloid leukemia is even rarer entity. Here we report a case of acute myeloid leukemia following human leucocyte antigen (HLA) matched sibling peripheral blood stem cell transplant (PBSCT) in a case of SAA. The patient achieved complete remission (CR) following chemotherapy and in CR1, a second HLA matched PBSCT from a different donor was offered. The patient is presently in remission at day +180 post-PBSCT.

Introduction: Hairy cell leukemia is a rare chronic B-cell disorder that follows an indolent but progressive course. This disorder is characterized by pancytopenia, splenomegaly, bone marrow fibrosis and the presence of atypical lymphoid cells with hairy projections in peripheral blood, bone marrow and spleen. Treatment is mainly with nucleoside analog cladribine, which induces complete remission in up to 85% cases. Materials and Methods: This is a retrospective analysis of Hairy cell Leukemia cases diagnosed and treated in the Department of Hematology, All India Institute of Medical Sciences, New Delhi between 2002 and 2013. Various parameters such as clinical features, laboratory parameters including complete blood cell count, bone marrow findings, cytochemistry, immunophenotyping by flowcytometry or immunohistochemistry, treatment protocol and complications secondary to treatment and relapse were reviewed. Results: A total of 35 cases were diagnosed during this period of 12 years of which 27 received cladribine and went in to remission. Median follow-up duration was 26 months. 5 (18%) cases had a relapse and all relapsed cases achieved second remission with cladribine; however, there was no case of second malignancy in our cohort. Conclusion: Cladribine has emerged as the treatment of choice for hairy cell leukemia given that the overwhelming majority of patients achieve long-lasting complete remissions. Upon relapse, these patients could be successfully salvaged with cladribine retreatment.

Dear editor, Priapism, that is, persistent penile erection that continues hours beyond, or is unrelated to, sexual stimulation, is a relatively uncommon disorder and is a medical emergency. Typically, only the corpora cavernosa are affected [1]. The term priapism was derived from the Greek god Priapus, son of Aphrodite who was born with oversized genitals [2]. The haematological causes for priapism include Sickle cell anaemia, Leukaemia, Multiple myeloma, Paroxysmal nocturnal haemoglobinuria, Thalassaemia, Thrombocythemia and Henoch–Schonlein purpura [3]. As far as hemoglobinopathies are concerned, priapism is most often encountered in sickle cell disease in 38–42 % of cases followed by sickle/beta thalassemia [4, 5]. Priapism is also noted in patients with sickle cell trait even though the incidence is low as compared with sickle cell anaemia [6–9]. However, so far priapism in Hb E homozygosity is not reported in literature. In this correspondence we intend to bring to notice an unusual association of priapism with Hb E homozygosity. A 27 years old male, resident of North Eastern part of India was referred to our haematology OPD to rule out any underlying haematological disorder as the individual had an episode of priapism 3 months ago. The patient had an episode of unprovoked painful persistent erection for more than 8 h for which he sought medical advice. The surgeon at that medical center had managed with therapeutic needle aspiration from corpora cavernosa combined with flushing of cavernosa with normal saline to clear the sludged blood. The patient’s symptom subsided subsequently with the intervention and was referred to our center for further evaluation. On detailed clinical history, the individual was not on any medication for chronic illnesses; neither was he abusing any psychoactive drugs, alcohol, no history of prior trauma to the perineal region. His physical examination revealed mild pallor. There was no hepatosplenomegaly or lymphadenopathy. Systemic examination did not reveal any abnormality. On USG abdomen, spleen was not reported as enlarged (Span 13 cms). On investigations, haemoglobin, total leucocyte count and platelet count were 9.1 gm/dL, 7.1 9 10/lL and 118 9 10/lL respectively. Peripheral smear examination revealed microcytic hypochromic red cells and target cells with normal differential leucocyte count and reticulocyte count of one percent. There were no sickle cells or atypical cells in peripheral smear and sickling test was also negative. Subsequently Hb HPLC was performed which revealed with Hb A2 ? E of 92.6 % (Retention time3.68 min), Hb A of 6 % (Retention time 2.29 min) and Hb F (Retention time 1.06 min) of 1.6 % (Fig. 1; Table 1). This was followed by parental study which revealed Hb A2 ? E in mother and father of 29 and 27 % respectively suggestive of both parents being heterozygous for Hb E, S. Venkatesan A. Purohit (&) M. Aggarwal P. K. Singh T. Seth H. P.

Background: Bleeding is a common clinical presentation. Even patients with mild bleeding disorders are extensively investigated for ascertaining the cause. The present study was conducted in order to evaluate the extent of the possibility of diagnosis in mild bleeding disorders. Material and Methods: This was a prospective study of patients referred for work up of mild bleeding for a period of 13 months. A complete blood count, peripheral smear examination, Prothrombin time, Partial Thromboplastin time and Thrombin Time, Platelet Aggregometry test, tests for von Willebrand’s disease and Platelet function 3 availability were measured. Results: 164 patients presented with mild bleeding, in 114 of the patients a single site of bleeding was present. Epistaxis was the most common presentation (39%). Cutaneous bleeding (petechiae and purpura) was the next common site. History of a major bleeding tendency in the family was present only in 11 patients. The investigations showed that VWD (17/164), followed by clotting disorders (CD) mainly mild hemophilia (15/164) were the most common diagnosable cause. There were also 4 cases of hypofibrinogenemia. The disorders of platelets (Platelet function defects/PFD) were the least common (9/164). Rest 123 (75%) patients could not be diagnosed on the basis of these investigations and were labeled as Bleeding disorders – Unclassified (BDC). Conclusion: n our study, 75% of the patients with mild bleeding remained undiagnosed even after extensive laboratory workup, thus raising a very pertinent question that is it necessary that all mild bleeders submit to a broad battery of investigations, as the diagnosis continues to be elusive despite extensive workup.

b>Introduction and Materials and Methods: Early diagnosis of sepsis is extremely important to reduce high mortality and morbidity. In this study, clinical usefulness of the volume, conductivity and scatter parameters (mean channels of cell volume, conductivity, and light scatter) in neutrophils was analyzed for predicting acute bacterial infection, which are obtained by the Coulter LH 750 Hematology Analyzer (Beckman Coulter, Fullerton, CA, USA) during automated differential counts. Results: Peripheral blood samples from 162 patients with positive blood cultures for bacteria and 40 healthy controls were studied. We observed a significant increase in the mean channel of neutrophil volume (MNV) from septic patients compared with control subjects (156 ± 13.5 vs. 143 ± 4.8; P < 001). Discussion and Conclusion: An elevation of the MNV was associated with a higher white blood cell count and percentage of neutrophils and was present even in patients who did not have leukocytosis or neutrophilia. With a cut-off of 149 for the MNV, a specificity of 91.4% and sensitivity of 88.7% were achieved. As a quantitative, objective, and more sensitive parameter, we propose that the MNV has a potential to be an additional indicator for acute bacterial infection.

T lymphoblastic leukaemia (T-ALL) is a neoplasm of lymphoblasts committed to T-cell lineage and T-ALL is diagnosed by identification of immaturity markers and the lineage specific Cluster of Differentiation (CD) marker, CD3 in the leukemic cells. Here we report a 20 year old male who was diagnosed as case of T-ALL, whose leukemic blasts on morphology resembled the lymphoid cells seen in hairy cell leukemia (HCL) resulting in a diagnostic dilemma which was resolved subsequently by immunophenotyping. Even though the presence of cells with hairy projections is rarely reported in haematological malignancies other than HCL, ours is a first of its kind in TALL.

A middle aged male presented to us with an unusual problem when his acute lymphoblastic leukemia (ALL) disappeared without any chemotherapy. We faced a dilemma whether to go ahead and treat his initial diagnosis or wait. Eventually he did relapse and was treated, albeit with a fatal outcome. Such spontaneous remission in acute leukemia are a very rare event, more common in acute myeloid leukemia and in children. Spontaneous remission in adult ALL is rarely described in literature.
