An Open-Label Randomized Controlled Trial Comparing Effectiveness of Aggressive Hydration Versus High-dose Rectal Indomethacin in the Prevention of Postendoscopic Retrograde Cholangiopancreatographic Pancreatitis (AHRI-PEP).

BACKGROUND: 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. STUDY: 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. RESULTS: 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. CONCLUSIONS: vHR with LR is noninferior to postprocedure per-rectal Indomethacin for PEP prevention (ClinicalTrials.govID:NCT03629600).

Deep vein thrombosis in a patient of adenomatous polyposis coli treated successfully with aspirin: A case report.

BACKGROUND: Deep vein thrombosis is an important cause of morbidity and mortality. However, its association with adenomatous polyposis coli is extremely rare. Here we present an interesting case of deep vein thrombosis associated with adenomatous polyposis coli. CASE PRESENTATION: A 15 year old female who was having fever and diarrhea for 5 months developed bilateral asymmetric painful swelling of lower limbs for 1 month. Doppler ultrasound of lower limbs revealed presence of thrombosis from inferior vena cava up to popliteal vein. Colonoscopy and biopsy were suggestive of adenomatous polyposis coli. However, she could not tolerate anticoagulant therapy and was put on aspirin therapy for 6 months to which she responded well with the resolution of thrombus. CONCLUSION: Role of aspirin therapy may be considered whenever a patient of venous thrombosis cannot tolerate anticoagulant therapy.

Multifocal Tubercular Osteomyelitis with Tubercular Breast Abscess: An Atypical Presentation of Tuberculosis.

Tuberculosis of spine is common in a developing country like India. However, involvement of spine at multiple levels along with involvement of rib and tubercular breast abscess in an immunocompetent patient without any pulmonary involvement is extremely rare. Here we report a case of 53-year-old immunocompetent lady who presented with quadriparesis and MRI (magnetic resonance imaging) of spine revealed multiple lesions involving cervical, thoracic, lumbar, and sacral region without any involvement of intervertebral disc. On detailed examination she was found to have a lump in right breast. Fine needle aspiration cytology of both paravertebral collection and breast lump revealed presence of acid fast bacilli. She was put on antitubercular drug for one year and she responded well to therapy.

Pure Motor Axonal Neuropathy, Organomegaly, Impaired Glucose Tolerance, M Protein, Skin Changes, Multiple Plasmacytomas & Acute Interstitial Nephritis in Osteolytic Myeloma: Beyond POEMS!

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.

Single nucleotide polymorphism network: a combinatorial paradigm for risk prediction.

Risk prediction for a particular disease in a population through SNP genotyping exploits tests whose primary goal is to rank the SNPs on the basis of their disease association. This manuscript reveals a different approach of predicting the risk through network representation by using combined genotypic data (instead of a single allele/haplotype). The aim of this study is to classify diseased group and prediction of disease risk by identifying the responsible genotype. Genotypic combination is chosen from five independent loci present on platelet receptor genes P2RY1 and P2RY12. Genotype-sets constructed from combinations of genotypes served as a network input, the network architecture constituting super-nodes (e.g., case and control) and nodes representing individuals, each individual is described by a set of genotypes containing M markers (M = number of SNP). The analysis becomes further enriched when we consider a set of networks derived from the parent network. By maintaining the super-nodes identical, each network is carrying an independent combination of M-1 markers taken from M markers. For each of the network, the ratio of case specific and control specific connections vary and the ratio of super-node specific connection shows variability. This method of network has also been applied in another case-control study which includes oral cancer, precancer and control individuals to check whether it improves presentation and interpretation of data. The analyses reveal a perfect segregation between super-nodes, only a fraction of mixed state being connected to both the super-nodes (i.e. common genotype set). This kind of approach is favorable for a population to classify whether an individual with a particular genotypic combination can be in a risk group to develop disease. In addition with that we can identify the most important polymorphism whose presence or absence in a population can make a large difference in the number of case and control individuals.

Churg-Strauss syndrome presenting with focal segmental glomerulosclerosis without proteinuria: response to unconventional therapy.

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.

Systemic Sclerosis Presenting with Simultaneous Retinal Vasculitis in One Eye and Optic Neuritis in the other along with Severe Immune Haemolytic Anaemia.

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.

Gallbladder adenomyomatosis with tubercular portal lymphadenopathy masquerading as gallbladder carcinoma.

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.

Gastric adenocarcinoma associated with lymphangitis carcinomatosa, adrenal metastasis with ectopic ACTH syndrome and malignant common bile duct stricture.

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.

Surface tunability of nanoparticles in modulating platelet functions.

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.

Squamous cell carcinoma of proximal esophagus with simultaneous metastases to thyroid and sternum: a case report and review of the literature.

Clinically significant metastatic spread to the thyroid is considered uncommon in spite of the fact that thyroid is a highly vascularized organ. Though it is not a very uncommon finding at autopsies, it is rare to be found in clinical situations, especially in an individual without a prior history of malignancy. We present an apparently healthy 66 year-old male patient with squamous cell carcinoma of the proximal esophagus presenting as a thyroid nodule along with sternal deposit as a coincidental finding. Esophageal carcinoma rarely metastasizes to the thyroid. This case highlights the importance of thorough work-up when evaluating a thyroid mass/nodule. A high index of suspicion should be kept in mind in order to detect the unusual etiologies of thyroid conditions, especially when clinicopathological features are not characteristic for primary thyroid malignancies.

Malignant large cell calcifying sertoli cell tumor of testis with skip metastasis to lung presented with peutz-jeghers syndrome.

Large cell calcifying Sertoli cell tumor of the testis (LCCSCT) is a rare tumor that is usually benign and multifocal. It may be associated with hereditary endocrine anomalies such as Carney's and Peutz-Jeghers syndromes. It is a rare histological variant of sex cord stromal tumors. It is exceptional in elderly men and the outcome is rarely fatal. We report a case of LCCSCT in a 44 year-old man with fatal outcome. The tumor involved the right testis and several areas of the tunica albuginea were grossly invaded. It composed of cords and trabeculae of large polygonal cells embedded in a myxoid and fibrous stroma with areas of calcification along with nuclear atypia, necrosis, and abundant mitoses. The Peutz-Jeghers syndrome (PJS) is known to be commonly associated with ovarian tumors. However, its association with testicular tumors is uncommon. To the best of our knowledge, this is the eight such case being reported in the literature. Our case, to our knowledge, is the only other reported case of malignant large cell calcifying Sertoli cell tumor with clinical and histopathological features related to aggressiveness, such as large tumor size, cellular pleomorphism, high mitotic rate, necrosis and aneuploid deoxyribonucleic acid. Such characteristics are not found in benign large cell calcifying Sertoli cell tumors.

Left atrial extension of lung carcinoma simulating myocardial infarction, unusual presentation: case report and literature review.

Lung malignancy invading the left atrium is rarely seen. We present a patient with a fast growing symptomatic lung mass. Electrocardiogram showed persistent coving ST elevation with no biomarker change. Transthoracic echocardiography showed a large left atrial mass attached to the free walls and extended into its appendage. An apparent continuity with a large lung mass compressing left ventricular lateral wall was observed which was better evident in computed tomography of the chest.

Isolated traumatic bilateral first rib fracture: a rare entity.

Since the first rib is protected very well by the overlying soft tissue and bones, its fracture is a major injury and a considerable force is required to do it. Therefore, an isolated fracture of this rib is unusual. A 28-year-old healthy female had an accident while crossing the road and a heavy object fell on her. She had severe pain behind her clavicle region and was immediately hospitalized and examined. Thorough clinical examination and different relevant investigations surprisingly disclosed isolated bilateral first rib fracture which is a very rare clinical condition.

Therapeutic effects of nandrolone and testosterone in adult male HIV patients with AIDS wasting syndrome (AWS): a randomized, double-blind, placebo-controlled trial.

PURPOSE: 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. METHODS: 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. RESULTS: 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). CONCLUSION: Our trial demonstrates the superior therapeutic effects of nandrolone in male AWS patients, including the androgen deficient.

Intensive phase non-compliance to anti tubercular treatment in patients with HIV-TB coinfection: a hospital-based cross-sectional study.

We aimed to study the prevalence and determinants of non compliance to intensive phase anti tubercular treatment (ATT) in 111 HIV-TB coinfection patients, attending the APEX Referral Center for HIV/AIDS at Medical College, Kolkata with a specially-designed, semi-structured, pre-tested questionnaire. Compliance was defined as taking ≥95% of the total scheduled doses of anti-TB medicines during the intensive phase. Data was collected on socio-demographic parameters, disease information, patient's knowledge and barriers to treatment. The prevalence of non-compliance to ATT in HIV-TB coinfection patients was found to be 40.5% (95% C.I. = 30.5, 50.5). Multivariate logistic regression analysis showed that absence of proper counseling, lack of knowledge about correct route of TB transmission, visiting quacks during ATT and the urge to leave treatment once patient started feeling better were the significant determinants of non-compliance. "No Counseling" increased chances of non- compliance (adjusted O.R.) 47.12 times (95% C.I. = 7.99, 195.27); thereby being the single most influential variable towards the outcome. The present study finds an alarmingly high prevalence of non-compliance to ATT among HIV-TB coinfection patients. The results clearly indicate that adequate counseling about this coinfection and the importance of compliance, along with better patient-friendly orientation of DOTS programme is urgently needed. Collaborative TB-HIV activities are essential to ensure better ATT compliance in coinfection patients.

Dual antiplatelet therapy in ACS: time-dependent variability in platelet aggregation during the first week.

AIMS AND OBJECTIVES: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Non tuberculous mycobacteria and toxoplasma co-infection of the central nervous system in a patient with AIDS

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.

Dual antiplatelet drug resistance in patients with acute coronary syndrome.

AIMS AND OBJECTIVES: 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). MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
