Thyroid Dysfunction in Patients with and Without Venous Thromboembolism: a Case Control Study.

Recent studies report an association between thyroid dysfunction and venous thromboembolism (VTE). Considering the high prevalence of thyroid diseases in India, identification of thyroid dysfunction as a risk factor for VTE will have implications in management. The aim of study was to determine if thyroid dysfunction could be considered as risk factor for unprovoked VTE. The study was conducted on 102 patients with unprovoked VTE and 102 age and gender matched controls in a tertiary care centre. Clinical profile and thyroid function tests (Free T3, Free T4, TSH) including antibody profile (Anti TPO and Anti TG) were compared between two groups. Thyroid disease was identified in 34 cases and 14 controls (33.1% vs. 13.7%, P = 0.001) Out of 34 cases with thyroid dysfunction, 17 had subclinical hypothyroidism (SCH) while 6 out of 14 controls had SCH. Both thyroid dysfunction and SCH were found to be associated with unprovoked VTE, as compared with controls; [Odds ratio (OR) = 3.14, 95% CI 1.56-6.33, P = 0.001] and (OR = 3.71; 95% CI 1.4-9.9; P = 0.01) respectively. Thyroid dysfunction was significantly higher among patients with unprovoked VTE. Thyroid dysfunction, SCH were associated with unprovoked VTE.

The First Differentiated TB Care Model From India: Delays and Predictors of Losses in the Care Cascade.

To reduce TB deaths in resource-limited settings, a differentiated care strategy can be used to triage patients with high risk of severe illness (i.e., those with very severe undernutrition, respiratory insufficiency, or inability to stand without support) at diagnosis and refer them for comprehensive assessment and inpatient care. Globally, there are few examples of implementing this type of strategy in routine program settings. Beginning in April 2022, the Indian state of Tamil Nadu implemented a differentiated care strategy called Tamil Nadu-Kasanoi Erappila Thittam (TN-KET) for all adults aged 15 years and older with drug-susceptible TB notified by public facilities. Before evaluating the impact on TB deaths, we sought to understand the retention and delays in the care cascade as well as predictors of losses. During April-June 2022, 14,961 TB patients were notified and 11,599 (78%) were triaged. Of those triaged, 1,509 (13%) were at high risk of severe illness; of these, 1,128 (75%) were comprehensively assessed at a nodal inpatient care facility. Of 993 confirmed as severely ill, 909 (92%) were admitted, with 8% unfavorable admission outcomes (4% deaths). Median admission duration was 4 days. From diagnosis, the median delay in triaging and admission of severely ill patients was 1 day each. Likelihood of triaging decreased for people with extrapulmonary TB, those diagnosed in high-notification districts or teaching hospitals, and those transferred out of district. Predictors of not being comprehensively assessed included: aged 25-34 years, able to stand without support, and diagnosis at a primary or secondary-level facility. Inability to stand without support was a predictor of unfavorable admission outcomes. To conclude, the first quarter of implementation suggests that TN-KET was feasible to implement but could be improved by addressing predictors of losses in the care cascade and increasing admission duration.

--Eleven tips for operational researchers working with health programmes: our experience based on implementing differentiated tuberculosis care in south India.

Due to the workload and lack of a critical mass of trained operational researchers within their ranks, health systems and programmes may not be able to dedicate sufficient time to conducting operational research (OR). Hence, they may need the technical support of operational researchers from research/academic organisations. Additionally, there is a knowledge gap regarding implementing differentiated tuberculosis (TB) care in programme settings. In this 'how we did it' paper, we share our experience of implementing a differentiated TB care model along with an inbuilt OR component in Tamil Nadu, a southern state in India. This was a health system initiative through a collaboration of the State TB cell with the Indian Council of Medical Research institutes and the World Health Organisation country office in India. The learnings are in the form of eleven tips: four broad principles (OR on priority areas and make it a health system initiative, implement simple and holistic ideas, embed OR within routine programme settings, aim for long-term engagement), four related to strategic planning (big team of investigators, joint leadership, decentralised decision-making, working in advance) and three about implementation planning (conducting pilots, smart use of e-tools and operational research publications at frequent intervals). These may act as a guide for other Indian states, high TB burden countries that want to implement differentiated care, and for operational researchers in providing technical assistance for strengthening implementation and conducting OR in health systems and programmes (TB or other health programmes). Following these tips may increase the chances of i) an enriching engagement, ii) policy/practice change, and iii) sustainable implementation.

Incidence, Risk Factors and Prognosis of Hypokalaemia in Patients with Normokalaemia at Hospital Admission.

Background: Hypokalaemia (K+<3.5 mmol/L) is observed in 20% of hospitalised patients. Previous studies have often dealt with the symptoms, prevalence and risk factors in hospitalised patients. Very few studies have dealt with hospital-induced hypokalaemia. The aim was to determine the incidence, predisposing risk factors and prognosis of patients developing hypokalaemia after admission. Materials and Methods: A prospective observational study was performed for two months. Patients with at least two potassium values after admission and normal K values at admission were considered for inclusion. Clinical features, diagnoses, laboratory reports and treatment details, including antibiotics, were noted. Results: A total of 653 patients were studied; 138 (21.1%) developed hypokalaemia. Diabetes, ischaemic heart disease (IHD), heart failure, chronic kidney disease, hypertension, chronic liver disease and chronic obstructive pulmonary disease (COPD) were the most associated comorbidities. Urea, creatinine, transaminases and neutrophilia at admission differed significantly between those with and without hypokalaemia groups. Most patients developed mild hypokalaemia (78.2%). Hypokalaemia developed mostly on the second (22.4%) and third (24.6%) days of hospitalisation. Antibiotics were used in 60% of patients. The potassium values returned to normal within 2.5 ± 1.9 days. Three patients subsequently developed hyperkalaemia. Conclusion: Patients admitted under general medicine mostly developed mild hypokalaemia, even if they had multiple risk factors for developing hypokalaemia. Inpatient hypokalaemia had an incidence of 21%. An overwhelming majority (~88%) had at least one risk factor. Hypokalaemia was not attributed to causing mortality in any patient.

Prevalence of Overhydration in Patients on Maintenance Haemodialysis As Determined by Body Composition Monitor and Effects of Attaining Target Dry Weight.

INTRODUCTION: Fluid overload in chronic kidney disease (CKD) is an independent risk factor for all-cause mortality. The volume of ultrafiltrate removed during haemodialysis is usually assessed clinically. Assessment of overhydration by body composition monitor (BCM) using bioimpedance spectroscopy is an objective method. This study was conducted to identify the prevalence of overhydration in CKD patients on maintenance haemodialysis and thereby assess the effects of BCM targeted dry weight attainment. METHODS: All patients included in the study were assessed for one month before enrolment for blood pressure, intradialytic events during each dialysis and BP medications. Overhydration was defined as the ratio of overhydration to extracellular water (OH/ECW) > 1.1. Overhydrated patients were brought to BCM targeted dry weight by increasing ultrafiltrate to 500mL/week more than their routine intradialytic weight gain. The effect of attaining BCM target dry weight on blood pressure and intradialytic events were analysed. RESULTS: Out of 110 patients, overhydration was seen in 30 (27.2%); only 20 had clinically evident overhydration. Body composition monitor guided dry weight was achieved in 28 of the 30 patients after a mean duration of 20 weeks. After achieving the target dry weight, there was a significant reduction in intradialytic hypertension events (2.37 vs 1.82 events per session, p-value 0.01). Surprisingly, there was a reduction in episodes of intradialytic hypotension as well, though this did not reach statistical significance. There was a clinically significant reduction in mean systolic and diastolic blood pressures (mean of 5.7mmHg and 2.8mmHg, respectively). CONCLUSION: The study underlines the importance of BCM-based hydration status assessment and target dry weight attainment in better control of intradialytic events and blood pressure in patients on maintenance haemodialysis.

Percutaneous Nephrostomy in Complicated Urinary Tract Infections.

Background The study aimed to determine the various indications for percutaneous nephrostomy (PCN) primarily in patients with a urinary tract infection and to determine the various complications arising in these patients due to the procedure. Materials and methods A retrospective study of five-year data based on registers of the Department of Urology was performed. Among 716 patients, 226 inpatient data were obtained, curated, and analyzed. Indications for PCN, the periprocedural complications, the PCN's duration, details of antibiotics, risk factors for UTI, development of acute kidney injury, and renal replacement therapy were recorded. Results Patients were mostly female (53.1%, n=120/226). Malignancy (n=109, carcinoma cervix=68/109) and nephrolithiasis (n=70) contributed to 79.2%. Infections such as pyelonephritis, renal abscess, perinephric abscess, and genitourinary tuberculosis were identified in 47. Infectious diseases were significantly associated with younger age, female gender, diabetes, and prior pyelonephritis. PCN was placed at a median of two days after admission, and bilateral PCN was placed in 36 (15.2%) patients. Hydroureteronephrosis (probably infected) was an indication for PCN in 164/226 patients. In 33 patients with an infectious disease, PCN was performed for an obstructed urinary system. One major and two minor complications gave a rate of 0.06% for patients with infections, which was less than the accepted threshold of 4%. Conclusions We intended to study the utility and problems with placing a PCN catheter in patients with complicated urinary infections. We conclude that PCN is a safe and effective procedure in urinary tract infections with obstructed drainage.

Streptococcus gallolyticus-related spinal epidural abscess.

Spinal epidural abscess (SEA) is a surgical emergency if it causes paraplegia. Staphylococcus aureus and streptococci are the most common causes. Streptococcus gallolyticus has been reported to cause SEA only on three occasions earlier-all were associated with endocarditis or colonic malignancy. We report an older woman with diabetic ketoacidosis who presented with poorly localised back pain, fever and altered sensorium. Her lumbar puncture revealed frank pus, and MRI showed an SEA. She could not be weaned from mechanical ventilation post-surgical decompression, and she succumbed to ventilator-associated pneumonia. A triad of fever, back pain and neurological deficit should lead one to consider intraspinal suppuration. This report is the first S. gallolyticus-related SEA from India and the first in literature that was not associated with either endocarditis or colonic malignancy.

Scrub Typhus and COVID-19 Coinfection Unmasking Antiphospholipid Antibody Syndrome.

Scrub typhus is an acute febrile disease caused by Orientia tsutsugamushi with a clinical course varying from mild to fatal. Vascular thrombosis is rare in scrub typhus. There is an increased risk of thrombotic events in Coronavirus disease 19 (COVID-19). We report a young diabetic female who presented with pulmonary embolism, followed by deep venous thrombosis (DVT) and was found to have coinfection with scrub typhus and COVID-19 with underlying antiphospholipid antibody syndrome.

Melioidosis: A 5-year Review from a Single Institution in Pondicherry.

INTRODUCTION: Forty-four percent of global cases are predicted to occur in the Indian sub-continent, but less than 2000 cases have been reported. Though the number of predicted cases in India is reported to be high, lesser numbers are being reported due to a lack of diagnostic capabilities and poor awareness of the disease. AIMS: We aimed to estimate the number of cases of melioidosis over a 5-year period, the proportion of non-survivors, and map the geographical regions of the patients. METHODS: Retrospectively, medical case records were reviewed with the search terms melioidosis and Burkholderia pseudomallei. Data on the geographical region, risk factors, clinical manifestations, and outcomes were collected and analysed. RESULTS: Thirty-four patients with melioidosis were found. 12/34 had died in the hospital. Case records of only 20 patients (M=19, F=1) could be traced. Patients who died were older and had a longer duration of symptoms, had higher total leukocyte counts, higher platelet counts, and more severe hepatic and renal dysfunction compared to those who survived. Being a teetotaller, having received intensive care, and mechanical ventilation showed statistical significance between the two groups. CONCLUSION: Three centres from Pondicherry have reported melioidosis; this study had the most significant reported number of cases from a single institution in Pondicherry. The mapping of our patients resulted in probable evidence of melioidosis in six other districts of Tamil Nadu. Since the Indian population is at high risk because of diabetes, and melioidosis can mimic tuberculosis, increased awareness among physicians is a must to diagnose and treat this disease with high mortality.

Diarrhea and Acute Tubular Necrosis Mimicking Hemolytic Uremic Syndrome in a Man With Immunoglobulin A (IgA) Nephropathy.

Immunoglobulin A (IgA) nephropathy is a heterogeneous disease with variable clinical presentations ranging from asymptomatic hematuria to advanced renal failure. A young male diagnosed with IgA vasculitis (skin, joints, and gastrointestinal) one month ago and placed on oral steroids presented with acute diarrhea, hemolytic anemia, renal failure (non-dialysis requiring), altered sensorium, and thrombocytopenia. The stool was found to be positive for Shiga toxin. He improved with methylprednisolone pulse alone, and renal biopsy showed acute tubular injury.

Concurrent Presentation of Emphysematous Pyelonephritis, Emphysematous Osteomyelitis, and Psoas Abscesses.

Emphysematous pyelonephritis (EPN) is an uncommon necrotizing infection commonly seen in people with diabetes. Emphysematous osteomyelitis (EOM) is a rare form of pyogenic osteomyelitis characterized by the presence of air in the bones. A combination of both these infections has been reported only thrice in the literature. We present the case of a middle-aged diabetic woman who had both these rare infections along with psoas abscesses, a phenomenon that has been described only once previously. The patient required prolonged hospitalization, surgical debridement and drainage, a double-J stent, and meropenem, and she subsequently achieved full recovery.

Acute cerebellar ataxia and peripheral neuropathy due to an atypical infection.

This 18-year-old boy presented to the hospital with symptoms of cerebellar dysfunction preceded by an acute febrile illness with rash. Examination showed evidence of left-sided cerebellar dysfunction and polyneuropathy. Empirical treatment for leptospirosis and scrub typhus was initiated. MRI was normal. Other organ dysfunctions in the form of thrombocytopenia and transaminitis were also observed. He recovered without sequelae. A diagnosis of acute cerebellar ataxia and polyneuropathy due to scrub typhus was made.

Empyema Tube or No Tube?

We report the case of a 36-year-old man with cirrhosis who presented with recurrent infection of his right-sided hepatic hydrothorax in the form of fever, dyspnea, and cough. The pleural fluid analysis showed transudative fluid with normal pH, lactic acid dehydrogenase, and glucose, but with Escherichia coli growth. An uncommon diagnosis of high mortality, spontaneous bacterial empyema was made. Criteria for chest tube drainage were met, but he was managed without one. He developed hospital-acquired pneumonia during his stay, but his pleural fluid showed the same characteristics. His empyema and pneumonia were managed with antibiotics and other supportive measures. On follow-up, he was readmitted on three other occasions with similar complaints and succumbed to upper gastrointestinal bleed during the fifth admission. A chest tube is not indicated in patients with spontaneous bacterial empyema unless frank pus is present.

Utility of platelet indices in alcoholic hepatitis: a retrospective study.

BACKGROUND: The commonly available platelet indices are platelet distribution width (PDW), plateletcrit (PCT), and mean platelet volume (MPV). They have been used in diagnosis and prognosis of various abdominal disorders. They have never been used to predict severity of alcoholic hepatitis. METHODS: A retrospective analysis of chronic alcohol consumers presenting with jaundice and deranged liver function tests was performed. Maddrey discriminant function (MDF) and modified end-stage liver disease (MELD) scores were calculated and patients compared between severe and nonsevere alcoholic hepatitis (MDF ≥32 vs MDF <32 and MELD >20 vs MELD ≤20). Logistic regression analysis was performed to find significant predictors. Receiver operating characteristic was used to find the area under the curve. Spearman correlation was performed to discover association between platelet indices and severity scores. RESULTS: There were 119 patients in the study. Coexisting illnesses included pancreatitis, cirrhosis, infections, and alcohol withdrawal syndrome. The mean age (years), duration of alcohol consumption (years), and ethanol (g/day) were 45.13 ±â€Š11.53, 18.84 ±â€Š11.40, and 65.61 ±â€Š45.42, respectively. The average MELD and Maddrey scores were 14.13 ±â€Š5.17 and 36.45 ±â€Š29.63, respectively. The mean platelet counts, PDW, MPV, and PCT were 194.01 ±â€Š178.82 × 109/L, 17.10 ±â€Š1.21, 5.99 ±â€Š0.96, and 0.14 ±â€Š0.04, respectively. PDW >18 and MPV had a significant positive correlation with MELD scores. Only bilirubin and prothrombin prolongation were significant predictors of severe alcoholic hepatitis. The area under the curve was highest for PCT at 0.622 (P = .07; confidence interval = 0.500-0.743). CONCLUSIONS: Platelet indices appear to be significantly altered in alcoholic hepatitis, but they do not predict severe disease. Whether this inability to predict severe alcoholic hepatitis is due to coexisting illnesses such as pancreatitis, cirrhosis, and infection needs to be studied further.

The Utility of Platelet Indices in Predicting Multiorgan Dysfunction in Scrub Typhus.

Platelet indices have been used to diagnose and prognosticate infections such as tuberculosis, malaria, dengue, and septic shock. Platelet indices have previously not been used in the prediction of multiorgan dysfunction (MODS) in patients with scrub typhus. A three-year retrospective review of patient charts was performed. Patients with and without MODS were compared. Platelet indices and other clinical and laboratory variables were used in logistic regression analysis to determine significant predictors. A ROC curve was generated with the platelet indices to predict MODS. Of 189 patients, 106 were male. Respiratory rate, serum creatinine, liver function tests, platelet count, thrombocytopenia <150 × 109/L, mean platelet volume (MPV) > 7.3 fL, and plateletcrit ≤0.19% varied significantly between patients with MODS and those without. Platelet indices are inexpensive and easily available. Only thrombocytopenia along with creatinine, alanine transaminase, and abnormal chest radiograph could significantly predict MODS in patients with scrub typhus.

Idiopathic CD4 Lymphocytopenia: Current Insights.

Idiopathic CD4 lymphocytopenia is a condition characterized by low CD4 counts. It is rare and most of the information about this illness comes from case reports. Presentation is usually in the 4th decade of life with opportunistic infections, autoimmune disease or neoplasia. The pathophysiology of this condition is not well understood. Management revolves around treatment of the presenting condition and close follow-up of these patients. This review presents a narrative summary of the current literature on idiopathic CD4 lymphocytopenia.

Acute Parkinsonism and Cerebral Salt-wasting-related Hyponatremia in Scrub Typhus.

Scrub typhus is a multisystem disease, and the respiratory system is commonly involved. Scrub typhus-related parkinsonism has been reported in three patients previously, and none of them underwent a lumbar puncture. Cerebral salt wasting is generally observed in vascular emergencies of the brain. We report a patient with acute parkinsonism and cerebral salt wasting syndrome, a combination of which has not been previously reported in scrub typhus. A 50-year-old farmer presented with an acute febrile illness of two weeks' duration and a one-day history of parkinsonism symptoms. His workup revealed hypoosmolar hyponatremia, increased urinary sodium excretion, hepatorenal and hematological dysfunction, and normal findings on cerebrospinal fluid examination. Clinical and biochemical improvement was noticed with the institution of doxycycline. Empirical doxycycline may be needed in patients with acute parkinsonism following an acute febrile illness in areas endemic for scrub typhus. Better biochemical facilities in resource-poor tropical countries would help in evaluating the etiology of hyponatremia due to infectious causes.

Electrocardiogram Heart Rate as a Predictor of Severity in Acute Alcohol-Related Pancreatitis With Alcohol Withdrawal Syndrome.

Background The severity of acute alcohol-related pancreatitis (AAP) with alcohol withdrawal syndrome (AWS) has not been studied. Electrocardiogram (ECG) has not been used as a predictor of severity in patients with AWS and acute pancreatitis. Objectives The study aimed to determine whether the ECG heart rate (HR) could predict the severity of AAP; secondarily, whether AWS influenced the severity of AAP based on Acute Physiology and Chronic Health Evaluation (APACHE) II and Bedside Index for Severity in Acute Pancreatitis (BISAP). Methods Demographics, comorbid illnesses, AWS, biochemistry, ECG, arterial blood gases, and CT findings were noted in patients with AAP. The severity of pancreatitis was scored into mild, moderate, and severe based on CT. BISAP, APACHE II, and ECG heart rate-APACHE (E-APACHE) were compared in patients with and without AWS. A receiver operating characteristic curve was used to find the best predictor of severity. Results Among 138 patients (M=128), 94 had AWS. ECG changes (≥1) were seen in 50%. Patients with AWS were younger, had consumed alcohol for a shorter duration, had higher systemic inflammatory response syndrome (SIRS), APACHE II, and E-APACHE II scores. APACHE II and E-APACHE II correlated significantly with severity grading, HR, alcohol duration, and AWS. HR was the best predictor of severe pancreatitis; E-APACHE was the best predictor for moderately severe pancreatitis. Conclusions Mostly, AAP appears to be mild; >2/3rds have AWS. ECG findings were seen in 50%. HR has not been previously studied in patients with both AAP and AWS and is an easy and inexpensive test to predict the severity of pancreatitis in this cohort.
