Red cell distribution width and neutrophil-lymphocyte ratio as inflammatory markers in patients with rheumatoid arthritis.

Introduction: The aim was to study the red cell distribution width (RDW) and neutrophil-lymphocyte ratio (NLR) as inflammatory markers and their correlation with clinical disease activity parameters in patients with rheumatoid arthritis (RA). Material and methods: This observational cross-sectional study included 100 randomly selected patients with RA. Disease Activity Score with 28-joint counts and erythrocyte sedimentation rate (DAS28-ESR) was taken as a marker of disease activity. The diagnostic value of NLR and RDW in RA was assessed. Results: The majority (51%) of cases showed mild disease activity. The mean NLR in cases was 3.88 ±2.59. Mean RDW was 16.25 ±2.49%. Neutrophil-lymphocyte ratio significantly correlated with ESR (p = 0.026), severity of pain (p = 0.013), osteoporosis (p = 0.014) and radiographic joint erosions (p = 0.048), but not with DAS28-ESR (p > 0.05) and C-reactive protein (CRP) (p > 0.05). Red cell distribution width showed a significant correlation only with NLR (p = 0.009). The positive predictive values of NLR and RDW for disease activity were 93.3% and 90% and the negative predictive values were 20% and 16.7% respectively. For NLR, the area under the curve (AUC) was 0.78 (p = 0.001) and at a cut-off value of 1.63, the diagnostic sensitivity was 97.7% and specificity 50%. For RDW, the AUC was 0.43 (p = 0.40) and at a cut-off value of 14.52, the diagnostic sensitivity was 70.5% and specificity 41.7%. The sensitivity and specificity of NLR were higher than those of RDW. A significant difference was seen between the AUC of NLR and RDW (p = 0.02). Conclusions: Neutrophil-lymphocyte ratio is a valuable inflammatory marker in patients with RA, but RDW is not useful in this regard.

Vitamin E-induced coagulopathy in a young patient: a case report.

BACKGROUND: High-dose vitamin E intake is known to inhibit vitamin K-derived coagulation factor synthesis, which can cause serious bleeding events such as gastrointestinal bleeding and intracranial hemorrhage. We report a case of coagulopathy induced by marginally increased levels of vitamin E. CASE PRESENTATION: A 31-year-old Indian man presented with oral bleeding, black tarry stools, and bruising over his back. He had been taking non-steroidal anti-inflammatory drugs for low backache and vitamin E for hair loss. He had mild anemia with normal platelet count, thrombin time, and prolonged bleeding time, activated partial thromboplastin time, and prothrombin time. Serum fibrinogen was slightly raised. Mixing studies with pooled normal plasma, aged plasma, and adsorbed plasma were suggestive of deficiency of multiple coagulation factors due to acquired vitamin K deficiency. Serum phylloquinone was normal, while prothrombin induced by vitamin K absence-II level was increased. Serum alpha-tocopherol was slightly raised. Upper gastrointestinal endoscopy showed multiple gastroduodenal erosions. A final diagnosis of vitamin E toxicity-related coagulopathy was made. The patient responded well to pantoprazole, vitamin K supplementation, multiple fresh frozen plasma transfusions, and other supportive treatments besides the discontinuation of vitamin E supplementation. The coagulation parameters normalized, and the patient was discharged with complete resolution of symptoms and remained asymptomatic during the follow-up for 6 months. CONCLUSIONS: Vitamin E-related inhibition of vitamin K-dependent factors with coagulopathy may occur even at marginally increased levels of serum vitamin E. This risk becomes significant in patients receiving other drugs that may increase the risk of bleeding.

Association between iron deficiency anemia and chronic daily headache: A case-control study.

OBJECTIVE: We aimed to determine the association between iron deficiency anemia and chronic daily headache. METHODS: This case-control study was conducted in a tertiary care center in Dehradun, India. One hundred patients with chronic daily headache were randomly selected for the study with an equal number of controls. Subsets of chronic daily headache were diagnosed as per the 3rd edition of the International Classification of Headache Disorders. The study participants were assessed for iron deficiency anemia. RESULTS: The mean age of the patients was 51.1 ± 22.1 years. Male: female ratio was 1:1.08. Chronic migraine was present in 62 (62%), tension-type headache in 23 (23%), and new daily persistent headache in 15 (15%) patients. The majority (96%) of patients had chronic daily headache of mild to moderate severity. Chronic daily headache was of long duration in all patients. Sixty-four (64%) patients had anemia of which 51 (51%) patients had iron deficiency anemia. Iron deficiency anemia showed a significant association with chronic daily headache (p < 0.001), but not with its type, subtype, and duration. Severe iron deficiency anemia had a significant association with the severity of chronic daily headache (p = 0.021). Serum iron, ferritin, total iron-binding capacity, and transferrin saturation also had a significant association with chronic daily headache (p < 0.05 for each), but not with its type, subtype, duration, and severity. Logistic regression analysis showed that iron deficiency anemia, total iron-binding capacity, and transferrin saturation had an independent association with chronic daily headache (p < 0.05 for each). CONCLUSIONS: Iron deficiency anemia had an independent association with chronic daily headache. Severe iron deficiency anemia was related to the severity of chronic daily headache.

Tobacco smoking-related risk for iron deficiency anemia: A case-control study.

BACKGROUND: Globally, iron deficiency anemia (IDA) is a significant public health problem. Tobacco smoking as a risk factor for anemia is often ignored. AIMS: To study the tobacco smoking-associated risk for IDA.This study was conducted in a tertiary care hospital in Dehradun, India from January 2019 to December 2020. One hundred ten patients having IDA (serum ferritin < 15 mcg/l) and an equal number of controls were randomly selected and assessed regarding their tobacco smoking status and type, quantity, and duration of tobacco used. RESULTS: Seventy-six (69.1%) patients with IDA were tobacco smokers and were predominantly males (51cases, 67.1%) and beedi smokers (52 cases, 68.4%). The odds ratios (ORs) for the association of smoking tobacco (cigarette and beedi collectively), cigarette, and beedi with IDA were 7.60 (p < 0.0001), 2.79 (p = 0.01), and 5.68 (p < 0.0001), respectively. OR for developing IDA was more among light smokers (OR = 7.72, p < 0.0001) and increased with duration of smoking (p < 0.0001). IDA was not significantly associated with confounding risk factors like malnutrition (OR = 1.00, p = 1.00), low socioeconomic status (OR = 0.64, p = 0.21), dietary habits (OR = 1.43, p = 0.45), and place of residence (OR = 0.93, p = 0.88). CONCLUSIONS: Tobacco smoking has a strong association with IDA. Both beedi smoking and cigarette smoking have a significant association with IDA. The risk of IDA is more among light smokers and is duration-dependent.

Spontaneous spinal intradural hemorrhage in dengue fever: a case report.

BACKGROUND: Spontaneous spinal cord hemorrhage is extremely rare in dengue fever. We report a case of spontaneous spinal intradural hemorrhage in dengue fever associated with severe thrombocytopenia. CASE PRESENTATION: A 48-year-old Indian woman presented with fever and body aches followed by acute onset of paraplegia with bladder and bowel dysfunction and loss of sensations below the level of the umbilicus. She had severe thrombocytopenia and positive dengue serology. Magnetic resonance imaging of the spine showed compression of the spinal cord due to intradural hematoma at the D7-D8 vertebral level. The patient received symptomatic treatment for dengue fever and steroids. Emergency D7-D8 laminectomy with excision of the clot and dural repair was done after stabilizing the platelet count with multiple platelet transfusions. The constitutional symptoms responded well to the treatment. There was good improvement in sensory symptoms but negligible improvement in paraplegia with a change in muscle power from grade 0/5 to grade 1/5 in the postoperative period. The patient was discharged from the hospital in a stable condition, but paraplegia showed little improvement during follow-up of 1 year. CONCLUSIONS: Spontaneous spinal cord hemorrhage can present as acute paraplegia in dengue fever. Failure to recognize this complication can delay initiating appropriate treatment with permanent loss of neurologic function.

Effects of Diaphragmatic Breathing and Systematic Relaxation on Depression, Anxiety, Stress, and Glycemic Control in Type 2 Diabetes Mellitus.

This prospective study assessed the effects of diaphragmatic breathing and systematic relaxation on depression, anxiety, and stress levels, as well as glycemic control, in patients with type 2 diabetes mellitus (T2DM). One hundred patients with T2DM were randomly assigned to two equal groups: Group A patients received conventional treatment for T2DM, and Group B patients received conventional treatment for T2DM plus training in diaphragmatic breathing and systematic relaxation and home practice of these stress-management techniques for 6 months. Stress, depression, and anxiety levels, blood sugar, and glycated hemoglobin (HbA1c) were recorded at baseline and after 6 months of treatment in all patients. Baseline characteristics were compared using the chi-square test and student's t test. Changes in mental well-being and glycemic status were assessed for their significance in each group using student's t test and compared between two groups using one-way analysis of covariance (ANCOVA). Baseline levels of the respective change outcome and duration of diabetes were used as covariates in the ANCOVA. A significant decrease was seen in depression, anxiety, and stress scores in Group B, but in Group A only the stress score decreased after 6 months. A significant decline occurred in blood sugar (fasting, 2-hour postprandial, and random) and HbA1c in both groups after 6 months. There was a larger decrease in depression and anxiety scores and HbA1c in Group B than in Group A. The decrease in HbA1c was significantly correlated with the decrease in anxiety and stress scores in both groups and with the depression score in Group A. Thus, the addition of diaphragmatic breathing and systematic relaxation to conventional T2DM treatment appears to have led to improvement in mental well-being and glycemic control in patients with T2DM.

Child-Turcotte-Pugh Score, MELD Score and MELD-Na Score as Predictors of Short-Term Mortality among Patients with End-Stage Liver Disease in Northern India.

BACKGROUND AND OBJECTIVES: Child-Turcotte-Pugh (CTP), Model for End-Stage Liver Disease (MELD) and MELD-sodium (MELD-Na) scores are used for predicting disease severity and mortality among patients with end-stage liver disease. However, data regarding their usefulness in predicting the short-term outcome of end-stage liver disease are not available in India. This prospective study compared the CTP score, MELD score and MELD-Na score as predictors of short-term outcome among patients with end-stage liver disease. METHODS: CTP, MELD and MELD-Na scores were determined in 171 patients with end-stage liver disease at a tertiary healthcare centre in India at the time of admission, and the concordance (C-) statistics of the three scores for 3-month mortality were assessed and compared. The aetiology of end-stage liver disease and the clinical presentation were determined. RESULTS: The CTP score, MELD score and MELD-Na score on day 1 were significantly higher among non-survivors than among survivors (p < 0.0001 each). The C-statistic for 3-month mortality for the CTP score was 0.93 (p < 0.0001), that for the MELD score was 0.86 (p < 0.0001) and that for the MELD-Na score was 0.83 (p < 0.0001). The C-statistics of these scores differed significantly for 3-month mortality, and the CTP score was better than the MELD (p < 0.0001) and MELD-Na (p < 0.0001) scores in predicting 3-month mortality. CONCLUSIONS: The CTP, MELD and MELD-Na scores were very good predictors of mortality at 3 months among patients with end-stage liver disease. The CTP score was superior to the MELD and MELD-Na scores in predicting 3-month mortality.

Tobacco smoking as a risk factor for tuberculous pleural effusion: a case-control study.

This study assessed the tobacco smoking-associated risk for tuberculous pleural effusion (TPE) in India. Ninety-two patients with TPE and 184 controls were randomly selected and assessed regarding their tobacco-smoking status and type, quantity and duration of tobacco used. Odds ratios (ORs) for the association of smoking cigarette, beedi and cigarette or beedi with TPE were 19.22 (p < 0.0001), 2.89 (p = 0.0006) and 4.57 (p < 0.0001) respectively. ORs for developing TPE increased with an increase in beedi/cigarette consumption, duration and pack years of smoking (p < 0.001 each). TPE was significantly associated with confounding risk factors viz., regular alcohol use (OR = 1.89, p = 0.019), history of contact with tuberculosis (TB) patient (OR = 8.07, p < 0.0001), past history of TB (OR = 22.31, p < 0.0001), family history of TB (OR = 9.05, p = 0.0002) and underweight (OR = 3.73, p = 0.0009). Smoking (OR = 3.07, p < 0.001), regular alcohol use (OR = 2.10, p = 0.018), history of contact with TB patient (OR = 4.01, p = 0.040), family history of TB (OR = 10.80, p = 0.001) and underweight (OR = 5.04, p < 0.001) were independently associated with TPE. Thus, both cigarette- and beedi-smoking have a significant association with TPE. The risk for TPE in tobacco smokers is dose- and duration-dependent.

A study on multi-organ dysfunction syndrome in malaria using sequential organ failure assessment score.

PURPOSE: The purpose of this study is to examine the prevalence, clinical spectrum, prognostic factors, and outcome of multi-organ dysfunction syndrome (MODS) in patients with malaria. MATERIALS AND METHODS: One hundred and twenty-four patients with malaria, diagnosed by a positive peripheral blood film and rapid malaria test, were studied for MODS using the sequential organ failure assessment (SOFA) score. The severity of malaria was assessed by the WHO criteria. RESULTS: Severe malaria was present in 54 (43.54%) patients. MODS was detected in 108 (87.09%) patients with malaria (Plasmodium falciparum - 57 [85.07%], Plasmodium vivax - 46 [88.46%] and mixed P. falciparum and P. vivax malaria - 5 [100%] cases). SOFA scores of MODS-and non-MODS-patients differed significantly (P < 0.001). No significant association was seen between MODS and type of malaria (P = 0.894). Mortality among malaria patients with MODS was 5.55% (6/108) (P. falciparum 8.77% [5/57] and P. vivax 2.17% [1/46]). The outcome of MODS was associated significantly with the severity of the SOFA score at admission (P = 0.011) but not with the type of malaria, malaria parasite index, and the number of organs involved (P > 0.05 each). The SOFA score at admission correlated significantly with the duration of hospitalization (P < 0.0001). CONCLUSIONS: MODS occurs with high frequency in malaria and is not dependent on the type of malaria. The outcome of MODS and recovery time depends on the severity of MODS. The SOFA score is useful in detecting MODS and ascertaining its severity and prognosis in malaria.

Profile of Acute Kidney Injury in Patients with Decompensated Cirrhosis at a Tertiary-Care Center in Uttarakhand, India.

OBJECTIVES: To study the clinical profile and predictors of acute kidney injury (AKI) in patients with decompensated cirrhosis. MATERIALS AND METHODS: This observational study was conducted at Himalayan Institute of Medical Sciences, Dehradun, India, on 175 consecutive patients with decompensated cirrhosis. Patients were studied for AKI as per International Club of Ascites-AKI criteria. RESULTS: The prevalence of AKI was 40.6%, with prerenal AKI 67.6%, hepatorenal syndrome (HRS) 23.8%, intrinsic renal AKI 7%, and postrenal AKI 1.4%. Mean arterial pressure (MAP), platelet count, and serum albumin were significantly lower and total leucocyte count (TLC), blood urea nitrogen, serum creatinine (SCr), total bilirubin, aspartate aminotransferase, international normalized ratio, Child-Turcotte-Pugh (CTP) score, and model for end-stage liver disease (MELD) score higher in cirrhosis patients with AKI than without AKI (p < 0.05 each). MAP, hemoglobin, TLC, and SCr were significantly different in various types of AKI (p < 0.05 each). AKI had a significant association with CTP score, alcohol, spontaneous bacterial peritonitis (SBP), sepsis, and shock (p < 0.05 each). Type of AKI had significant association with SBP, sepsis, and shock (p < 0.05 each). Mortality occurred in 33.8% patients with AKI with 64.7% mortality in patients with HRS. Outcome had significant association with AKI, stage and type of AKI (p < 0.05 each). Multivariate analysis showed SBP, sepsis, and shock as independent predictors of AKI (p < 0.05 each). CONCLUSIONS: AKI occurred commonly in patients with decompensated cirrhosis. Prerenal AKI and HRS were the most common types of AKI. SBP, sepsis, and shock were important predictors of AKI.

Orbital Myiasis with Scalp Pediculosis and Buccal Abscess-An Uncommon Presentation.

We present a case of severe orbital myiasis caused by Osteris ovis, also known as sheep nasal botfly which is an uncommon manifestation of maggot infestation. Our patient was successfully treated with oral as well as topical ivermectin. The experience of ivermectin as an anti-parasitic agent in the treatment of orbital myiasis, although a known entity, is still limited among medical professionals including ophthalmologists. Thus, we would like to highlight the role of oral ivermectin as an anti-parasitic agent in the treatment of orbital myiasis facilitating the removal of maggots; thus, precluding the need for exploratory surgery.

Echocardiographic evaluation of left ventricular diastolic dysfunction in subclinical hypothyroidism: A case-control study.

PURPOSE: To study the prevalence of left ventricular diastolic dysfunction (LVDD) in patients with subclinical hypothyroidism (SCH) and the response of LVDD to L-thyroxine therapy. MATERIALS AND METHODS: This cross-sectional case-control study with one longitudinal arm included 67 patients with SCH attending a tertiary care hospital in Uttarakhand, India, and 67 age- and sex-matched healthy controls. LVDD was assessed by 2D, pulsed-wave Doppler (PWD), continuous wave Doppler (CWD), and tissue Doppler echocardiography (TDE). Patients with LVDD received L-thyroxine therapy with reassessment for LVDD 6 months later. RESULTS: SCH patients had a higher prevalence of LVDD than controls (13.43% versus 1.49%; p = 0.017). LVDD showed a significant association with gender (p = 0.004) and serum FT4 (p = 0.001). E velocity, E' velocity, A' velocity, iso-volumetric relaxation time (IVRT), E/A, and E'/A' ratios were significantly lower, while A velocity, deceleration time (DT), E/E' ratio, left atrial (LA) volume index, and peak tricuspid regurgitation (TR) velocity were significantly higher in cases than controls (p < 0.05 each). The E/A ratio correlated significantly with age, serum very low-density lipoprotein (VLDL), triglycerides (TG), thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and high-density lipoprotein (HDL) (p < 0.05 each). E' velocity correlated significantly with age, serum total cholesterol, VLDL, and TG (p < 0.05 each), DT with serum total cholesterol (p = 0.047), and LA volume index with age (p = 0.021). Age (p = 0.016) and serum HDL (p = 0.029) were independent predictors of E/A ratio. Gender was an independent predictor for LVDD (p = 0.003). Echocardiographic indices for LVDD showed significant improvement after 6 months of L-thyroxine therapy (p < 0.05 each). CONCLUSIONS: LVDD occurs commonly in SCH patients. It can be detected timely using echocardiography and may be reversed by L-thyroxine therapy.

Risk factors for angiographically proven coronary artery disease in women in India.

Coronary artery disease (CAD) is a significant cause of mortality in women. Risk factors for CAD may vary in different populations. We assessed the risk factors for angiographically proven CAD in women in India in this case-control study. Women with normal coronary arteries served as controls. High prevalence of conventional CAD risk factors was seen in women with CAD, but significant association with CAD was not present for all risk factors. Oral contraceptive pill use and family history of CAD were important risk factors for CAD in premenopausal women, while reproductive span was an additional factor influencing premature CAD.

Malarial hepatopathy: Clinical profile and association with other malarial complications.

This prospective study assessed the incidence, clinical profile and outcome of malarial hepatopathy and its association with other complications in patients with malaria, proved by peripheral blood smear examination and rapid malaria test. Hyperbilirubinemia (Serum bilirubin >3mg/dL) with >3-fold rise in serum aminotransferases in absence of a different explanation for such derangement was considered as malarial hepatopathy. Of 134 (falciparum-81, vivax-48 and mixed falciparum and vivax-5) malaria cases, hyperbilirubinemia occurred in 41.04%. Serum aspartate aminotransferase (AST) was raised >3-fold in 17.16% and serum alanine aminotransferase (ALT) in 4.47% cases. Malarial hepatopathy was observed in 4.47% (falciparum-5 and vivax malaria-1) cases, but had insignificant association with the type of malaria (p=0.532). Serum bilirubin, AST and ALT levels were higher while age was lower in both overall (p<0.05 each) and falciparum malaria cases with hepatopathy than without hepatopathy (p<0.05 each). Malarial hepatopathy was associated with a higher incidence of cerebral malaria, shock, acute respiratory distress syndrome (ARDS) and acute kidney injury in both overall (p<0.05 each) and falciparum malaria (p<0.05 each) and hyponatremia and disseminated intravascular coagulation only in overall malaria (p<0.05). Malarial hepatopathy had significant association with duration of hospitalization, parasite clearance time, fever clearance time and jaundice clearance time in overall (p<0.05 each) and falciparum (p<0.05 each) but not vivax malaria cases (p>0.05 each). Mortality occurred in 1 (20%) case of falciparum-induced hepatopathy with an overall mortality of 16.66%. ARDS (p=0.003) and shock (p=0.026) were independently associated with malarial hepatopathy overall while only ARDS with falciparum-induced hepatopathy (p=0.006). Thus, hepatocellular dysfunction is common in malaria but that qualifying as malarial hepatopathy is not common. Malarial hepatopathy is likely to occur in presence of other malarial complications. It is an epiphenomenon in severe malaria and indicative of severe disease. Establishing a particular association with malaria or mortality would require a larger case-control study of severe malaria.

Pattern Reversal Visual Evoked Potential and Cognitive Functions in Subclinical Hypothyroid Subjects.

BACKGROUND: Central nervous system (CNS) involvement is insidious and may occur early in subclinical hypothyroid (SCH) state which can be picked up by electrophysiological study. This study aims to record visual evoked potential (VEP), event-related latency and cognitive functions, and find their association with the levels of serum thyroid-stimulating hormone (TSH) in patients with SCH. MATERIALS AND METHODS: In this cross-sectional study, 36 adult SCH patients and an equal number of age- and sex-matched euthyroid controls were included. Pattern reversal VEP, visual reaction time (RT), digit spanning test, and AB clock test (ABCT) were done in both SCH cases and euthyroid controls. The observed values were analyzed for comparison of mean values between the groups and correlation of recorded variables with the levels of serum TSH. RESULTS: SCH cases showed a higher P100 (VEP) latency in both the right (103.2 ± 12.3 vs. 102.7 ± 6.8 ms) and left eye (101.1 ± 9.1 vs. 96.2 ± 10.7 ms) as compared to controls, but the difference was statistically insignificant. A significant delay in RT was observed on visible spectra of light in SCH cases (P < 0.001). Digit spanning score (forward and backward) in SCH cases was significantly lower than controls (P < 0.001), and a lower standardized score (<124 or <95th percentile) was significantly associated with SCH state (P = 0.027). No significant difference was observed in visuospatial domain by ABCT between both the groups although the median score was lower in SCH cases. Only digit spanning score showed a significant negative correlation with TSH levels (r = -0.4; P = 0.001). CONCLUSION: Decline in working memory and RT to visual stimuli is an evidence of the involvement of CNS in SCH. Prolonged latency in VEP may depend on the duration of SCH.

Scrub typhus in Uttarakhand & adjoining Uttar Pradesh: Seasonality, clinical presentations & predictors of mortality.

BACKGROUND & OBJECTIVES: Scrub typhus is a re-emerging mite-borne rickettsiosis, which continues to be underdiagnosed, with lethal consequences. The present study was conducted to determine the seasonality, clinical presentation and predictors of mortality in patients with scrub typhus at a tertiary care teaching hospital in northern India. METHODS: Scrub typhus was suspected in patients attending the hospital as per the standard case definition and serological evidence was obtained by performing an IgM ELISA. RESULTS: A total of 284 patients with scrub typhus from urban and rural areas were seen, predominantly from July to November. The most common clinical presentation was a bilateral community-acquired pneumonia (CAP), which resembled pneumonia due to atypical pathogens and often progressed to acute respiratory distress syndrome (ARDS). An acute undifferentiated febrile illness (AUFI) or a febrile illness associated with altered sensorium, aseptic meningitis, shock, abdominal pain, gastrointestinal bleeding or jaundice was also seen. Eschars were seen in 17 per cent of patients, and thrombocytopenia, transaminitis and azotaemia were frequent. There were 24 deaths (8.5%) caused predominantly by ARDS and multi-organ dysfunction. The mortality in patients with ARDS was high (37%). ARDS [odds ratio (OR)=38.29, 95% confidence interval (CI): 9.93, 147.71] and acute kidney injury (OR=8.30, 95% CI: 2.21, 31.21) were the major predictors of death. INTERPRETATION & CONCLUSIONS: The present findings indicate that scrub typhus may be considered a cause of CAP, ARDS, AUFI or a febrile illness with multisystem involvement, in Uttarakhand and Uttar Pradesh, especially from July to November. Empiric therapy of CAP may include doxycycline or azithromycin to ensure coverage of underlying unsuspected scrub typhus.

Echocardiographic evaluation of diastolic dysfunction in rheumatoid arthritis - a case-control study.

OBJECTIVES: To assess left ventricular diastolic dysfunction (LVDD) and its predictors in rheumatoid arthritis (RA). METHODS: This cross-sectional case-control study assessed 100 RA patients and 100 healthy controls for LVDD by M-mode, two-dimensional, colour Doppler echocardiography. RESULTS: RA patients had higher prevalence of LVDD than controls (43% vs. 14%; p < 0.001). LVDD had significant association with duration (p = 0.033), severity of disease activity (p < 0.0001), Steinbrocker stage and functional class (p < 0.0001 each) and non-adherence to treatment (p = 0.047). Peak of late diastolic (A) mitral flow velocity and isovolumic relaxation time (IVRT) were higher (p < 0.05 each), whereas left ventricular ejection fraction, peak of early diastolic (E) mitral flow velocity and E/A ratio were lower (p < 0.05 each) in RA patients than in controls. Deceleration time (DT) was not significantly different in the two groups (p = 0.623). E/A ratio had significant correlation with anti-cyclic citrullinated peptide antibody (ACPA) (r = 0.233, p = 0.019) and age (r = 0.203, p = 0.042). IVRT had significant negative correlation with ACPA (r = -0.196, p = 0.044), while DT had significant correlation with Disease Activity Score with 28-joint (DAS28) counts (r = 0.244, p = 0.014). ACPA was an independent predictor of E/A ratio (p = 0.031). DAS28 was the only independent predictor of LVDD (odds ratio [OR] = 6.01; p = 0.007). CONCLUSIONS: LVDD occurred commonly in RA patients and depended on severity of disease activity.

Multiple eschars in scrub typhus.

An eschar is highly suggestive of scrub typhus in a case of fever. Multiple eschars are rare in scrub typhus. We present a picture of multiple eschars in scrub typhus.

Model for end-stage liver disease score versus Maddrey discriminant function score in assessing short-term outcome in alcoholic hepatitis.

BACKGROUND AND AIMS: The Maddrey Discriminant Function (mDF) score and the Model for End-Stage Liver Disease (MELD) score are standard prognostic scores for predicting disease severity and mortality in alcoholic hepatitis (AH).This prospective study compared the MELD score and the mDF score as predictors of short-term outcome in AH. METHODS: The admission MELD score and the mDF score were assessed in 47 patients with a diagnosis of AH in the Himalayan Institute Hospital, Dehradun, India and the concordance (C) statistics of the two scores for 28-day mortality were determined and compared. RESULTS: Both the MELD score and the mDF score on day 1 were significantly higher in non-survivors than in survivors (P = 0.0001 each). The C-statistic for 28-day mortality for the MELD score was 0.91 (P < 0.0001, 95% confidence interval [CI] 0.79-0.97) and for the mDF score 0.90 (P < 0.0001, 95% CI 0.78-0.97). There was no significant difference between the C-statistics of the two scores (P = 0.83, 95% CI -0.07 to 0.09). For predicting 28-day mortality, the optimal MELD score of > 19 (sensitivity 91.6% and specificity 85.7%) corresponded to the mDF score of > 52.8 (sensitivity 91.6% and specificity 82.8%). CONCLUSIONS: Both the MELD score and the mDF score at admission were strong and equally good predictors of 28-day mortality in patients with AH, but the optimal mDF score corresponding to optimal MELD score was higher than the conventional one. Thus, MELD score may be used as an alternative to mDF score for predicting short-term mortality in AH with an advantage.

Visceral leishmaniasis with associated common, uncommon, and atypical morphological features on bone marrow aspirate cytology in nonendemic region.

Objectives. The present study was conducted to categorise the morphological features on bone marrow aspirate cytology into common, uncommon, and atypical features in a nonendemic region which would be helpful in clinching an early and correct diagnosis especially in clinically unsuspected cases. Methods. The morphological features on bone marrow were categorized into common, uncommon, and atypical in cases of leishmaniasis from non endemic region. Results. Out of total 27 cases, 77.7% were residents of places at the height of 500 m or above and fever was the most common presentation followed by hepatosplenomegaly. Plasmacytosis, hemophagocytosis were the common cytological features while dysmyelopoiesis, presence of leishmania bodies in nonhistiocytic cells, and granuloma with necrosis were uncommon features. Aggregates of LD bodies in form of ring, floret, or strap shapes along with giant cells constitute the atypical morphological features. Conclusion. The knowledge of common, uncommon, and atypical features on bone marrow aspirate cytology is helpful in clinching an early and correct diagnosis of leishmaniasis especially in non endemic areas where clinical suspicion is low. These features will guide the pathologist for vigilant search of LD bodies in the marrow for definite diagnosis and thus will also be helpful in preventing unnecessary workups.
