Cardiac Troponin-T levels in heart blood as a marker to diagnose postmortem myocardial infarction .

Cardiac deaths account for 50% of all deaths in developed and 25% in the developing world. One-sixth of world’s population lives in india and heart diseas accounts for 24% of all deaths. Sudden death accounts for two-thirds of all autopsies in Forensic Medicine Actual detection of histological. sequence of the infected myocardium will develop only after significant time of, between onsets of myocardial infarction (MI) in death. Cardiac Troponin-T is not normally present in serum unless cardiac necrosis has occurred therefore cardiac Troponin levels act as a specific and sensitive indication of myocardial infarction. The present study was conducted on cases coming for medico legal autopsy to the Forensic Medicine Department at Gandhi Medical College/Hospital, Hyderabad, Andhra Pradesh, India for a period of 1 year from January 2014 to December 2014. Total 12 cases with 6 controls were analyzed. Cardiac Troponin-T was markedly elevated >2.000 ng/ml in all except one case of suspected MI. Sensitivity was found to be 91.66% and specificity 66.66%.

Plasmid-mediated quinolone resistance in typhoidal Salmonellae: A preliminary report from South India.

Background: Fluoroquinolones are the drugs extensively employed for the treatment of Salmonella infections. Over the couple of decades that have elapsed since the introduction of fl uoroquinolones, resistance to these agents by Enterobacteriaceae family members has become common and widespread. Although fl uoroquinolone resistance is mediated by genomic DNA (deoxyribonucleic acid) as well as plasmid DNA, the plasmid-mediated quinolone resistance (PMQR) facilitates higher level resistance by interacting with genomic mechanism and is capable of horizontal spread. Materials and Methods: During a period of 1-year, 63 typhoidal Salmonellae were isolated from 14,050 blood cultures and one parietal wall abscess. 36 (56.25%) were Salmonella Typhi and 27 (42%) were Salmonella Paratyphi A. They were all screened for resistance by the disc diffusion method and their minimum inhibitory concentrations were determined using agar dilution, broth dilution and E-strip method. Ciprofl oxacin resistant isolates were screened for PMQR determinants by polymerase chain reaction assay. Results: All the 63 isolates were resistant to nalidixic acid. Among the 36 S. Typhi isolates 20 were resistant to ciprofl oxacin, of which 14 carried the plasmid gene qnrB and one carried the aac(6’)-Ib-cr gene. qnrA and qnrS genes were not detected. Ciprofl oxacin resistance was not seen in any of the S. Paratyphi A isolates. Conclusion: The antibiotic sensitivity pattern of typhoidal Salmonellae shows an increasing trend of PMQR. The allele B of qnr gene was found to be the predominant cause of PMQR in this study.

Non-syndromic multiple odontogenic keratocysts: report of case / Keratocistos múltiplos não-sindrômicos: relato de caso

Odontogenic keratocysts (OKCs) are epithelial developmental cysts which were first described byPhillipsen in 1956. Lesions are frequently multiple and a component of Nevoid Basal Cell CarcinomaSyndrome (NBCCS) (Gorlin Goltz syndrome/Bifid rib syndrome). We hereby report a case of multipleOKCs in a non – syndromic patient and highlight the general practitioner the importance of diagnosingthe disease and enforcing a strict long-term follow-up whenever such a case is identified.

Os keratocistos odontogênicos são cistos de desenvolvimento que foram descritos primeiramentepor Phillipsen, em 1956. As lesões são frequentemente múltiplas, sendo componentes da síndromedo carcinoma nevoide de células basais (síndrome de Gorlin, síndrome das costelas bífidas).Descreve-se um caso de keratocistos múltiplos em paciente não-sindrômico, enfatizando-se aimportância do clínico geral no diagnóstico da doença e reforçando a necessidade de umapreservação a longo prazo tão logo a doença seja diagnosticada.

Periductal stromal sarcoma of breast with lipoblast-like cells: a case report with review of literature.

The specialized mesenchyme of the breast is the seat of neoplasms with distinct morphology, though with considerable overlap due to the ever increasing number of variants. This article seeks to describe the morphologic features of one such rare neoplasm. A 35-year-old female patient presented with a breast lump that was subsequently excised. Morphological assessment and immunohistochemistry were performed and a diagnosis of periductal stromal sarcoma with lipoblast-like cells (pseudolipoblasts), was made. Being an unusual finding in a rare entity of intermediate grade, it has to be considered, before rendering a diagnosis of a malignant, higher-grade neoplasm.

Nasal NK/T cell lymphoma presenting as a lethal midline granuloma.

Nasal NK/T cell lymphomas are aggressive, locally destructive, midfacial, necrotizing lesions. The nonspecific clinical symptoms constitute a major stumbling block in the early diagnosis and management of these lymphomas. We report here a case of probable nasal NK/T cell lymphoma in an apparently healthy male that progressed rapidly in a short span of time and was managed subsequently with chemotherapy and external beam irradiation with which the lesion regressed.

Endometrial stromal nodule with smooth muscle differentiation.

Uterine tumors composed of a prominent component of smooth muscle and endometrial stroma (so-called stromomyoma) are distinctly uncommon. This article describes the morphological features of one such tumor discovered as an incidental finding in a hysterectomy specimen of a 49-year-old lady with a clinical diagnosis of dysfunctional uterine bleeding. Morphological and immunohistochemical (IHC) evaluation were performed and a final diagnosis of endometrial stromal nodule with smooth muscle differentiation was rendered.

Potential for osseous regeneration of platelet-rich plasma--a comparative study in mandibular third molar sockets.

Platelet-rich plasma (PRP), the concentrate of platelets in plasma contains various growth factors that enhance osseous regeneration. This study utilized homologous platelet-rich plasma in the treatment of third molar extraction sockets in a total of fourteen human subjects, who were randomly assigned into one control and one test group, each comprising of seven members. Clinical parameters like pain on palpation, number of analgesic tablets consumed, swelling, degree of mouth opening, and condition of mucosa overlying the surgical site were assessed at intervals of 1,3,5,7,9,12, and 16 weeks post operatively. The margins between the socket and surrounding bone, radiopacity of bone filling the socket, and presence oftrabecular bone formation were evaluated simultaneously. Soft tissue healing differed significantly between the two groups, with the test group exhibiting better results. Radiographic evidence of bone formation was visible as early as I week in test subjects. It was concluded that PRP contributed to better healing of soft tissues and bone and is a viable means of growth factor delivery.

Analgesic activity of Piper longum Linn. root.

Piper longum root, commonly called Kandantippili, is traditionally used to treat rheumatism, insomnia, palsy and epilepsy. But a scientific study on its central actions is not available. This study screens P. longum root for opioid type analgesia using rat tail-flick method and for NSAID type analgesia using acetic-acid writhing method. Pentazocine (ip) and ibuprofen (oral) are used as respective drug controls. An aqueous suspension of P. longum root powder is given orally to mice and rat in doses of 200, 400 and 800 mg/kg. The delay in reaction time for thermal stimulus in rats and the number of writhings to chemical stimulus in mice are determined in each group. The results are analysed statistically. The 400 and 800 mg/kg doses of P. longum show significant NSAID type of analgesia (P < 0.001). Both Ibuprofen (40 mg/kg) and P. longum (800 mg/kg) show 50% protection against writhing. The delay in reaction time to thermal stimulus was less than 6% for different doses of P. longum as against 100% for pentazocine. This indicates that P. longum root has weak opioid but potent NSAID type of analgesic activity.

An anticlastogenic in vivo micronucleus assay for tea.

Common use of antimutagens and anticarcinogens in everyday life is an effective measure for preventing human cancer and genetic diseases. Antioxidant properties of tea have vast potential as protective agents against diverse toxic effects. The present study was aimed to evaluate the role of aqueous clonal tea extracts (green tea, oolong tea and black tea) in modulating the genotoxic damage induced by cyclophosphamide (CP), a commonly used chemotherapeutic drug and a well-known mutagen and clastogen. All the three tea extracts at 1 and 2% concentration did not increase the frequency of micronucleated polychromatic erythrocytes (MPE) in bone marrow cells of mice when administered individually. The tea extracts decreased the micronuclei (MN) induced by CP. Therefore, regular intake of tea may improve the antioxidant status in in vivo and thereby reduce the risk of cancer and coronary heart disease.
