Aluminum Phosphide Poisoning Presenting like Acute Myocardial Infarction in a Young Girl.

Aluminium phosphide poisoning is very common in India. It is one of the most fatal poisons. The clinical spectrum of poisoning varies depending upon the dosage and duration of consumption. The main effect of the poison is due to the release of phosphine which inhibits cytochrome oxidase and thereby hampers cellular oxygen utilization. Almost any organ can be affected by aluminium phosphide poisoning. We report a case where the heart was the predominantly affected organ. Cardiac involvement usually manifests with nonspecific ST-T changes in ECG. Here we report a case presented with ECG finding mimicking acute anteroseptal myocardial infarction which is extremely rare.

Arteriolymphatic Fistula: An Extremely Uncommon Adversary and its Management.

A 66-year-old female patient underwent transfemoral coronary angioplasty. Three weeks after the procedure, she presented with abdominal pain. An abdominal computed tomography scan revealed an unusual femoral arteriolymphatic fistula, which was managed with selective angiography-guided glue embolization. (Level of Difficulty: Advanced.).

Clinical outcome of orbital apex syndrome in COVID associated mucormycosis patients in a tertiary care hospital.

AIM: To share clinical pattern of presentation, the modalities of surgical intervention and the one month post-surgical outcome of rhino-orbito-mucormycosis (ROCM) cases. METHODS: All COVID associated mucormycosis (CAM) patients underwent comprehensive multidisciplinary examination by ophthalmologist, otorhinolaryngologist and physician. Patients with clinical and radiological evidence of orbital apex involvement were included in the study. Appropriate medical and surgical intervention were done to each patient. Patients were followed up one-month post intervention. RESULTS: Out of 89 CAM patients, 31 (34.8%) had orbital apex syndrome. Sixty-six (74.2%) of such patients had pre-existing diabetes mellitus, 18 (58%) patients had prior documented use of steroid use, and 55 (61.8%) had no light perception (LP) presenting vision. Blepharoptosis, proptosis, complete ophthalmoplegia were common clinical findings. Seventeen (19.1%) of such patients had variable amount of cavernous sinus involvement. Endoscopic debridement of paranasal sinuses and orbit with or without eyelid sparing limited orbital exenteration was done in most cases, 34 (38.2%) patients could retain vision in the affected eye. CONCLUSION: Orbital apex involvement in CAM patients occur very fast. It not only leads to loss of vision but also sacrifice of the eyeball, orbital contents and eyelids. Early diagnosis and prompt intervention can preserve life, vision and spare mutilating surgeries.

Intra-Arterial Chemotherapy for Retinoblastoma: Four-Year Results from Tertiary Center in India.

BACKGROUND: There are limited reports of intra-arterial chemotherapy (IAC) for retinoblastoma (RB) from developing world. OBJECTIVES: In this study, we report our 4-year experience of IAC for RB from India. METHODS: Retrospective, interventional case series. Primary outcome measures included tumor regression, vitreous seeds and subretinal seeds control, and globe salvage. Secondary outcome measures were best-corrected visual acuity and treatment complications. RESULTS: Fifteen eyes underwent 53 IAC procedures over mean 28.6 ± 13.8 months (range 10-51 months). IAC was employed as primary (n = 6) or secondary (n = 9) chemotherapy. Following IAC, complete regression of main tumor was seen in 7 eyes (47%) and partial regression in 3 (20%) eyes. Enucleation was done in 5(33%) eyes. Globe salvage rates were achieved in 1 eye (100%) in group B, 2 eyes (67%) in group C (n = 3), 6 eyes (67%) in group D (n = 9), and 1 eye (50%) in group E (n = 2). Following IAC, Kaplan-Meier survival curve showed 93% globe survival rate at 1 year, 76% at 2 years, and 66% at 3, and 4 years. CONCLUSION: IAC has enhanced globe salvage rates in eyes with RB. Multicenter studies with longer follow-up are necessary to better understand outcomes in the long term.

Series of Atypical Rhinosporidiosis: Our Experience in Western Part of West Bengal.

Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi. It usually presents as sessile or pedunculated granular polyp, red in colour with multiple yellowish pin-head sized dots. Atypical presentations due to involvement of extra-nasal sites may produce diagnostic dilemma. Very high incidence of rhinosporidiosis and that too with atypical presentations in the rural western part of West Bengal, encourages us to undertake this study. The present study was conducted in a tertiary care hospital in the rural western part of West Bengal from July 2013 to December 2016. Patients presenting with rhinosporidiosis in extra-nasal sites and with atypical presentations were included in the study. Rhinosporidiosis confined to nose and patients who lost follow up were excluded from the study. All patients were treated with wide excision and cauterization of base. Among total 114 patients of rhinosporidiosis, 16 had atypical presentations (14.04%). Nine patients (56.25%) presented with a mass hanging in the oropharynx, some mimicking oropharyngeal malignancy. Two patients (12.50%) presented with acute respiratory distress and stridor. One patient (6.25%) presented with disseminated rhinosporidiosis with involvement of the skin, subcutaneous tissue, muscle, bone, penis and urethra. Recurrence was noted in only two patients (12.50%) in nasopharynx. This chronic disease may present with different acute presentations. Proper clinical eye may avoid pre-operative biopsy which may lead to extensive bleeding. Recurrence can be reduced with meticulous and complete removal. Regular post-operative follow-up with endoscopy is must to detect and treat early recurrence.

Human protein reference database--2006 update.

Human Protein Reference Database (HPRD) (http://www.hprd.org) was developed to serve as a comprehensive collection of protein features, post-translational modifications (PTMs) and protein-protein interactions. Since the original report, this database has increased to >20 000 proteins entries and has become the largest database for literature-derived protein-protein interactions (>30 000) and PTMs (>8000) for human proteins. We have also introduced several new features in HPRD including: (i) protein isoforms, (ii) enhanced search options, (iii) linking of pathway annotations and (iv) integration of a novel browser, GenProt Viewer (http://www.genprot.org), developed by us that allows integration of genomic and proteomic information. With the continued support and active participation by the biomedical community, we expect HPRD to become a unique source of curated information for the human proteome and spur biomedical discoveries based on integration of genomic, transcriptomic and proteomic data.

A Rare Case of Dense Spontaneous Echo Contrast within Inferior Vena Cava.

A 33-year-old gentleman was examined because of fatigue and progressive right heart failure. A striking finding in his echocardiogram was intense and slow-moving dense echo contrast in the inferior vena cava (IVC). Cardiac catheterization revealed constrictive pericarditis, and pericardiectomy was performed. Postoperatively spontaneous echo contrast in IVC have resolved. This case helps explain the origin of spontaneous IVC contrast.

Odontogenic Tumours of Jaw: A Prospective Study on Clinico-Pathological Profile and Their Management.

Odontogenic tumours are a group of heterogeneous diseases that range from hamartomatous or non-neoplastic tissue proliferations to benign neoplasms to malignant tumours with metastatic potential. They are rare, comprising about <2-3% of all oral and maxillofacial biopsy specimens. The aim of the present study was to determine the clinico-pathological presentation of this heterogeneous group of lesions and review of literature. The present study was conducted in the ENT department of a Government Medical College and Hospital, West Bengal, India, over the period of 5 years from January 2011 to December 2015. It included a total of 15 patients who were clinico-radiologically diagnosed as odontogenic tumours, and were given appropriate treatment. Their diagnostic and management approaches are discussed. Among 15 odontogenic tumours, 13 were benign and two were malignant. Male to female ratio was 2:3. Mandible to maxilla ratio was 1.8:1. The patients were in between 4 and 56 years of age with highest incidence in 3rd decade of life. All patients are doing well till date with a minimum follow-up of 1 year. Incisional biopsy is considered as gold standard for preoperative diagnosis but FNAC can offer clinicians a less invasive alternative. CT is the choice of investigation for study of lesion, analysis of its extension and surgical planning. The challenge to proper management lies in balancing between conservative and radical approach to reduce morbidity and recurrence both. Final diagnosis is made by post-operative histopathological examination.

Role of High Resolution Computed Tomography of Mastoids in Planning Surgery for Chronic Suppurative Otitis Media.

Chronic suppurative otitis media (CSOM) presents with a typical history of recurrent otorrhoea with tympanic membrane perforation. The diagnosis of cholesteatoma is usually made on otologic examination. High resolution computed tomography (HRCT) is indicated to evaluate the extension and the complications of cholesteatoma. The aim of the work was to study the role of HRCT in detecting, evaluating diagnosing and managing CSOM. All patients presenting with CSOM who were planned for mastoid exploration surgery in department of ENT, Gauhati Medical College and Hospital within a period of 2 years-from 1st January, 2013 to 31th December, 2014, were taken up for the study. HRCT mastoids done routinely before cholesteatoma surgery, but with improved resolution, to characterize all middle ear structures and complications of the disease prior to surgery, might guide as road map during mastoid explorations for unsafe CSOM. The important role of HRCT lies on the early detection of cholesteatoma, and more conservative surgical procedures can be used to eradicate the disease.

Plasma Proteome Database as a resource for proteomics research.

Plasma is one of the best studied compartments in the human body and serves as an ideal body fluid for the diagnosis of diseases. This report provides a detailed functional annotation of all the plasma proteins identified to date. In all, gene products encoded by 3778 distinct genes were annotated based on proteins previously published in the literature as plasma proteins and the identification of multiple peptides from proteins under HUPO's Plasma Proteome Project. Our analysis revealed that 51% of these genes encoded more than one protein isoform. All single nucleotide polymorphisms involving protein-coding regions were mapped onto the protein sequences. We found a number of examples of isoform-specific subcellular localization as well as tissue expression. This database is an attempt at comprehensive annotation of a complex subproteome and is available on the web at http://www.plasmaproteomedatabase.org.
