Although rectal administration of nonsteroidal anti-inflammatory drugs is recommended as the standard pharmacologic modality to prevent postendoscopic retrograde cholangiopancreatography (ERCP) post-ERCP pancreatitis (PEP), vigorous periprocedural hydration (vHR) with lactated Ringer's solution (LR) is emerging as an effective prophylaxis modality for PEP. There has been no head-to-head comparison between these 2.This was a single-center, randomized, open-label, noninferiority, parallel-assigned, equal allocation, controlled clinical trial in a tertiary care hospital. Consecutive adults referred for ERCP, satisfying predefined inclusion criteria, underwent simple randomization and blinded allocation into 2 groups. Those allocated to vHR received intravenous LR at 3 mL/kg/h during procedure, 20 ml/kg bolus immediately afterward, and then at 3 mL/kg/h for another 8 hours. Those randomized to rectal Indomethacin received only per-rectal 100 mg suppository immediately post-ERCP. Assuming PEP of 9% in Indomethacin arm and noninferiority margin of 4%, we calculated sample size of 171 patients in each arm for 80% power and α-error 5%. Primary outcome was incidence of PEP, within 1 week, as defined by Cotton's criteria. All analysis were done by intention-to-treat.Between October, 2017 to February, 2018, 521 patients were assessed. In all, 352 were enrolled, 178 randomized to vHR, and 174 to per-rectal Indomethacin. Baseline details and ERCP outcomes were not different between 2 groups. PEP occurred in 6 (1.7%) overall, with 1 (0.6%) in hydration arm, and 5 (2.9%) in indomethacin arm; an absolute risk reduction of 2.3% (95% confidence interval: 0.9%-3.5%) and odds ratio of 0.19 (95% confidence interval: 0.02-1.65). Three patients developed severe PEP, all receiving indomethacin.vHR with LR is noninferior to postprocedure per-rectal Indomethacin for PEP prevention (ClinicalTrials.govID:NCT03629600).

Ectopic adrenocorticotrophic hormone (ACTH) syndrome (EAS) commonly occurs secondary to neuroendocrine tumours and small cell carcinoma of lung. EAS has also been reported in association with gastric carcinoids. But, the occurrence of EAS secondary to gastric adenocarcinoma has rarely been reported. A 45-year-old male patient from Bangladesh presented with abdominal pain, jaundice and hyperpigmentation. Extensive work-up revealed poorly differentiating mucin-secreting adenocarcinoma of stomach with lymphangitis carcinomatosa of lung, bilateral adrenal metastasis and malignant common bile duct (CBD) stricture. Laboratory reports were suggestive for ectopic ACTH production. Most of these features are very rare in adenocarcinoma of stomach, and all these rare events occurring in a single patient is probably the rarest.

Metallic nanoparticles are attractive candidates as MRI contrast agents and mediators for drug delivery, diagnostics, and therapy. Direct contact and exposure to blood circulation is common in many such applications. The consequent thrombotic response may therefore be important to study. The main objective of the present work was to study how platelet functions were changed in the presence of different nano-surface or surface capping, which may provide a measure for the safety of a nanoparticle, and also assess the use of such nanoparticles in platelet modulation. Aggregometry, ATP release reaction, flow cytometry and immune-blotting studies were performed to study platelet response to different nano-particles (iron oxide, gold and silver). For each nanoparticle surface conjugation (capping) was varied. It was found that citric acid functionalized iron oxide nanoparticles have anti-platelet activity, with a decrease in aggregation, tyrosine phosphorylation level, and granule release. On the other hand in other cases (e.g. gold nanoparticles) pro-aggregatory response was observed in the presence of nanoparticles and, in some cases, the nanoparticles behaved neutrally (e.g. for starch-coated iron oxide nanoparticles). Therefore, nanoparticles can induce antiplatelet or a pro-aggregatory response, or remain neutral depending on surface capping. A related observation is that antiplatelet drugs can be made more potent by nanoparticle conjugation.

A 20-year-old boy presenting daily febrile episodes was suspected to have developed acute hepatic failure. Serologic tests ruled out infectious and autoimmune causes apart from drug toxicity. During clinical examinations, he was found to have generalized enlarged lymph nodes that were then taken biopsy. It was diagnosed as classical Hodgkin’s lymphoma based on histological examination of the lymph node. A bone marrow biopsy showed marrow infi ltration by Hodgkin’s lymphoma with hemophagocytosis and secondary myelofibrosis. A percutaneous liver biopsy demonstrated hepatic involvement of the same disease. After an extensive work-up, the cause of liver failure was figure out to be only attributed to the involvement of the lymphoma. Hodgkin’s lymphoma as a cause of hepatic failure is rare and young patients diagnosed as Hodgkin’s lymphoma causing hepatic failure has been reported very rarely so far.

Nodular lymphocyte predominant Hodgkin’s disease occurs in 5% of all cases of Hodgkin’s disease. It occurs more commonly in male. Only 5% of all Hodgkin’s lymphoma cases develop spinal cord compression[1] and in only 0.2% cases, spinal cord compression occurs as the initial presentation[2]. So our case is rare both in the form of the unique variety of Hodgkin’s disease and also in the form of presentation.

Acute coronary syndrome (ACS) covers a spectrum of clinical conditions ranging from unstable angina, Non-ST segment elevation myocardial infarction (NSTEMI), or ST segment elevation myocardial infarction (STEMI). This study encompasses patients with acute coronary syndrome, who were receiving the dual antiplatelet therapy of aspirin and clopidogrel. The focus of the study was to gain insight into the role of selective P2Y1 antagonism using MRS2179 in such cases as well as its effects, if any, on collagen-epinephrine interaction. All the cases showed greater potency of inhibition of the interaction when yohimbine hydrochloride (YH), a blocker of alpha2A-adrenoreceptor, was used compared to MRS2179, a P2Y1 antagonist, although there was variability in responsiveness to the antiplatelet drugs. These findings indicate that alpha2A-adrenoreceptors of platelets in this group play a major role in precipitating the interactive effect of collagen and epinephrine. The dose-response effect as studied by platelet aggregometry showed that the required molar concentration to block the interactive effect in the case of YH was less than that of MRS2179. Hence, it is postulated that although there may be an impairment of collagen-induced aggregation by MRS2179, the interactive effect of collagen-epinephrine may not be impaired by MRS2179 as efficaciously as YH.

Churg-Strauss syndrome (CSS), or allergic granulomatosis, is a rare disease manifested by tissue infiltration, hypereosinophilia and vasculitis. Renal involvement may be seen in up to 50% of cases. We report the case of a 25-year old man who presented with a history of fever for two months, tingling, numbness, and paraesthesia of the upper limbs and left lower limb, along with diarrhoea for one month and an inability to walk for the past seven days. Serial laboratory investigations helped to reach the final diagnosis of CSS with mononeuritis multiplex, and skin, pulmonary and gastrointestinal involvement with hypertension. This is due to renal involvement in the form of focal segmental glomerulosclerosis without any nephrotic range proteinuria, which is a very rare clinical entity. The patient's symptoms were relieved after the administration of an unconventional mode of therapy.

Gallbladder carcinoma is more likely to occur in elderly females and the presence of periportal adenopathy often signifies advanced disease. Such patients are generally not taken up for surgery and are treated palliatively. Isolated periportal tuberculosis without the evidence of disease elsewhere is in itself a rarity. Here we present a case study of gallbladder mass suspected of being gallbladder carcinoma with portal lymphatic metastasis actually turning out to be that of gallbladder adenomyoma with periportal tuberculosis. This case illustrates how mass lesions of the gallbladder are commonly and falsely interpreted to be malignant.

The association between pulmonary interstitial fibrosis and the development of bronchogenic carcinoma in a patient with scleroderma has been reported rarely[1]. It is hypothesized that intense epithelial proliferation that is accompanied by the fi brotic process increases the occurrence of carcinomatous changes[2]. We report the case of a patient who presented with 3-year history of Raynaud’s phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory distress with left shoulder and upper back pain followed by the development of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.

The authors describe a case of 52-year-old male who presented with sudden onset deterioration of weakness of both lower limbs and retention of urine. He had 1 month history of gradually progressive weakness of legs. On examination, there were lower motor neuron signs in lower extremity, digital clubbing and a lump over left iliac fossa. Routine blood tests showed impaired glucose tolerance, confirmed by oral glucose tolerance test while renal parameters were normal. Magnetic resonance imaging of spine documented osteolytic lesions, long segment epidural mass in thoracic spine and a mass overlying the left iliac bone, both were revealed to be plasmacytoma following cytology. Ultrasonography of abdomen showed splenomegaly. Nerve conduction studies showed gross axonal, motor, asymmetric polyneuropathy with conduction block involving all the four extremities, mainly lower limbs with sensory sparing. Serum protein electrophoresis showed M spike, and bone marrow showed diffuse neoplastic plasma cell proliferation. Osteolytic lesion was present in skull radiograph. Then in the course of illness the patient developed acute renal failure due to acute interstitial nephritis as evidenced from proteinuria and kidney biopsy, which improved with steroids and chemotherapy but unfortunately we lost the patient after 2 weeks of initiation of chemotherapy.

Systemic Sclerosis (SSc) is a connective tissue disorder which involves multiple systems in a chronic progressive manner. Micro–angiopathic haemolytic anaemia is a distinguished feature of “scleroderma renal crisis”, which is manifested by severe hypertension, a rapidly progressing renal dysfunction and hyperreninaemia and is seen in patients with an early, diffuse form of the disease. A nervous system involvement is rare, though entrapment neuropathies have been reported. Who presented with a sequential loss of vision in both eyes; due to retinal vasculitis in right eye and optic nerve demyelination in the left eye. She also had severe Coombs’ negative haemolytic anaemia in absence of any renal dysfunction or hypertension. Both the ophthalmologic and the haematologic manifestations are very rare and both responded well to oral prednisolone therapy.

Prevalence of pediatric HIV has not been well characterized. We evaluate the prevalence, risks and contributing factors to the spread of HIV in India. This manuscript aims to describe prevalence of Pediatric HIV infection in Eastern India. We want to provide data on burden of HIV positive children visiting a tertiary care center located in the city of Kolkata, East India. Data is provided for routes of HIV exposure and occupational background and HIV status of the parents of infected children. Background: Various studies in India have documented high prevalence of HIV infection in children. Nearly 20 million babies are born each year and the number of infected babies could be >50,000 per year. According to Solomon S et al in India the prevalence of HIV among pregnant women varies widely from state to state and figures range from 0.5% to as high as 4.7% as in Namakkal, a small village in Tamilnadu. Objective: To determine and characterize the prevalence of pediatric HIV/AIDS in India Methods: This is a two year retrospective review of patients from the (with 100 beds) pediatric outpatient unit of the Medical college and Hospital, Kokata, was undertaken to determine the prevalence of pediatric HIV/AIDS in Kokata (or in North India). Results: 3,669 pediatric patients were admitted to the hospital, 437(11.9%) tested positive for HIV, 234 were males, while 203 were females (m:f=1.15:1). Children under the age of five years accounted for 81.7% of the HIV positive children. Mother-to-child transmission occurred in 73.7% of cases was the major route of transmission of HIV. Two other common routes included the use of blood/blood products (21 patients), hairdressing implements due to punctures in 4.8% each, while sexual abuse/sex activities were the probable route in 3.8% others. Most mothers of HIV children were either housewives (45.3%), or petty traders, trade that is conducted on a small scale (10.4%). Conclusion: The prevalence of pediatric HIV/AIDS was high in Eastern india. The most common mode of transmission was mother to child. Programs to work on education of prevention of this mode of transmission should be implemented by proper detection of disease in mothers,adequate counselling and administration of HAART to prevent mother to child transmission of AIDS.

A 35 year-old male presented with left sided weakness for past 3 months, along with progressive deterioration in higher mental faculties, vision and audition. Clinical and investigational information suggested the diagnosis of an acute demyelination involving various areas of the brain. He was seropisitive for HIV and had good cellular immunity at the time of our assessment. We present this case to highlight the association of Multiple Sclerosis (MS) with HIV, either during seroconversion or early during course of this infection.

Two cases of haemophagocytic syndrome (HPS) due to histoplasmosis in patients with the acquired immunodeficiency syndrome (AIDS) are described in our case studies. Both the patients presented with pancytopenia and the bone marrow aspirate showed features suggestive of haemophagocytosis and the presence of intracellular inclusions were compatible with Histoplasma capsulatum. Haemophagocytic syndrome due to disseminated histoplasmosis should be included in the differential diagnosis of pancytopenia in patients with AIDS, though it is a rare clinical entity.

We aimed to compare therapeutic effects of intramuscular (IM) nandrolone decanoate and IM testosterone enanthate in male HIV patients with AIDS wasting syndrome (AWS) with placebo control.In this randomized, double-blind, placebo-controlled, 12-week trial, 104 patients with AWS who satisfied our inclusion criteria were randomly allotted in a 2:2:1 ratio to the 3 intervention groups: nandrolone, testosterone, and placebo. We administered 150 mg nandrolone and 250 mg testosterone (both IM, biweekly). The primary outcome measure was a comparison of absolute change in weight at 12 weeks between the nandrolone decanoate, testosterone, and placebo groups.Intent-to-treat analysis was done. The nandrolone group recorded maximum mean increase in weight (3.20 kg; post hoc P.01 compared to placebo). Body mass index (BMI) of subjects in the nandrolone group had a significantly greater increase (mean = 1.28) compared to both testosterone (post hoc P.05) and placebo (post hoc P.01). Waist circumference and triceps skinfold thickness of patients on nandrolone showed similar results. Nandrolone also ensured a better quality of life. Patients with low testosterone level (3 ng/mL) benefited immensely from nandrolone therapy, which increased their weight and BMI significantly compared to placebo (P.05).Our trial demonstrates the superior therapeutic effects of nandrolone in male AWS patients, including the androgen deficient.

Recurrent ischemic events continue to occur despite combination anti-platelet therapy. Currently aspirin, clopidogrel and dual resistance are increasingly recognized entities. The relationship of such resistance to recurrent ischemic events is largely unknown. In this study, we tried to gain an insight into the role of antiplatelet drug resistance with recurrent Acute Coronary Syndrome (ACS).The antiplatelet effect of aspirin and clopidogrel was studied in 40 recurrent ACS patients and 170 patients with first episode of ACS, afteror = 7 days of dual antiplatelet therapy. Platelet aggregation study was done with optical aggregometer. Resistance to aspirin and clopidogrel was defined asor = 50% aggregation with collagen and ADP respectively.Aspirin, clopidogrel and dual drug resistance were encountered respectively in 35%, 72.5% and 32.5% patients with recurrent ACS. The corresponding figures for the patients with first episode of ACS were 25.3%, 42.3% and 18.8% respectively. P values for the comparisons were 0.237 for aspirin, 0.0007 for clopidogrel and 0.084 for dual drugs. Patients with recurrent ACS were relatively younger and had a higher prevalence of conventional risk factors like hypertension, diabetes and elevated LDL.Antiplatelet drug resistance is likely to play an important role in recurrent ACS alongside other conventional risk factors. Further research is required in this field to have a definitive conclusion.

Platelets play an important role in the pathogenesis of Acute Coronary Syndrome (ACS). Most of the complications of ACS occur during the initial hours of presentation. We tried to gain an insight into the platelet function during the initial phase of ACS in patients on dual antiplatelet therapy.Platelet aggregation study was performed by light transmittance aggregometry in 64 ACS patients 48 hour and 7 days after initiation of dual antiplatelet therapy with aspirin and clopidogrel.Epinephrine, ADP and collagen induced platelet aggregation was significantly higher at 48 hours, following initiation of dual antiplatelet therapy, in comparison to the profile observed on the 7th day. Diabetics demonstrated a significantly higher aggregation at both the time points and aggregation was also somewhat higher in smokers though it did not reach statistical significance.This study conceptualizes the hypothetical role of alpha-2 adrenoreceptor blockers during the early hours following ACS and also warrants further investigations exploring the optimum loading dose of antiplatelet agents, especially clopidogrel in patients with ACS.

Antiplatelet therapy is a cornerstone in the management of the atherosclerotic vascular disease. Aspirin and clopidogrel are the two most commonly used antiplatelet drugs in its management. Recently, there has been a concern about the development of resistance to one or both antiplatelet agents with potentially devastating consequences. In this study we tried to assess the in vitro resistance to antiplatelet agents in patients presenting with acute coronary syndrome (ACS).144 patients presenting with ACS, who were not on any antiplatelet therapy prior to hospital admission were evaluated in this study. Baseline clinical data was obtained before giving the oral loading dose of aspirin and clopidogrel. Patients received a loading dose of 325 mg of aspirin and 300 mg of clopidogrel followed by a daily dose of 150 mg. of aspirin and 75 mg.of clopidogrel. After 7 days of dual antiplatelet therapy, platelet aggregation pattern was analyzed using optical aggregometer (chrono-log). Response to aspirin and clopidogrel was assessed by interaction with collagen (2microg/ml) and Adenosine diphosphate (ADP) (10micro/ml) respectively. The results were analyzed. Response to doubling the dose of antiplatelet agents was also observed in 6 aspirin resistant patients, 12 clopidogrel resistant patients and in 6 patients resistant to the effect of dual antiplatelet agents.There were 22 patients (15.27%) who showed poor response to aspirin, 28 patients (19.44%) to clopidogrel (primary non-responder) and 18 patients (12.5%) showed a primary non-responsiveness to both the antiplatelet agents in the usual doses. After dose doubling, all 6 aspirin resistant patients showed adequate response but 4 out of 12 clopidogrel resistant patients showed inadequate response.This pilot study brings out a disquieting picture of 12.5% patients suffering from ACS showing resistance to the antiplatelet effects of both aspirin and clopidogrel in the conventional dose. A long-term prospective randomized controlled trial is required to give an insight into this problem and its clinical consequences.

New-onset seizures are frequent manifestations in patients infected with Human Immunodeficiency Virus (HIV). We describe the clinical and radiological findings in an 25yr old AIDS patient presenting with new onset seizures as the primary manifestation of cerebral toxoplasmosis and Non Tuberculous Mycobacterial [NTM] co-infection. Cranial computed tomography showed a subtle ventricular dilatation whereas magnetic resonance imaging disclosed prominent temporal horn. Toxoplasma tachyzoites and rapidly growing mycobacteria were recovered from CSF. Seizures were complex partial in nature and refractory to antiepileptic therapy.
