Dhaka Zoo with 2000 animals of 184 species and five million visitors a year is important from a public health point of view. This study was conducted to investigate coccidioidomycosis in captive animals at Dhaka Zoo. One hundred and two tissue samples were collected and preserved in 10% neutral buffered formalin at necropsy of 36 animals of 25 species. Twenty five animals were suffering from granulomatous diseases, of which ten were identified as coccidioidomycosis. Clinical history, nodular lesions at necropsy, granulomatous lesions on histopathology and characteristic spores on special staining confirmed coccidioidomycosis in six rhesus macaques (Macaca mulatta), one horse (Equus caballus), one common langur (Presbytis entellus), one beisa oryx (Oryx beisa beisa) and one reticulated python (Python molurus). It is suggested that coccidioidomycosis in captive animals threatens human and animal health. DOI: http://dx.doi.org/10.3329/bvet.v30i2.18255 Bangl. vet. 2013. Vol. 30, No. 2, 54-61

Dhaka Zoo with 2000 animal heads of 184 species from significant genetic diversity and five million visitors’ influx round the year is placing it a public health important spot. This study was conducted to investigate histoplasmosis in animals at Dhaka Zoo to ascertain animal health, welfare and public health safety standard. One hundred and two necropsied tissue samples preserved in 10% neutral buffered formalin at necropsy from 36 animals of 25 different species were collected from Dhaka Zoo during 2007 - 2009. Twenty five out of 36 study animals were suffering from granulomatous diseases of mycotic and/or bacterial origin. Among them three animals were found suffering from histoplasmosis. Clinical history, nodular lesions from necropsy findings, granulomatous reactions with fungal spores on histopathology; macrophages laden with histoplasma organisms on histopathology and on special staining were revealed histoplasmosis in six rhesus macaques (Macaca mulatta). Present study provides evidence of existing histoplasmosis and similar long standing zoonotic diseases in majority of rest of the animals with health risk that shades health safety standard at Dhaka Zoo.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19145Bangl.

Il termine medicina narrativa, oggi ricorrente nella letteratura medica, evoca immediatamente l’importanza della storia clinica raccontata dal paziente come criterio irrinunciabile per formulare la diagnosi e definire l’opportuna terapia. In questa ottica, l’iter diagnostico è un atto ermeneutico “di racconti”. Molte pubblicazioni apparse su riviste mediche internazionali fanno riferimento al concetto del paziente come testo, inteso secondo diverse accezioni: the physical text, i segni fisici della malattia così come sono obiettivamente esaminabili; the experential text, il vissuto esistenziale della malattia; the instrumental text, i dati di laboratorio nonché i risultati degli esami strumentali; the narrative text, la storia clinica raccontata dal paziente. In questo articolo, un racconto di Cˇ echov, Caso clinico, viene utilizzato per illustrare diversi momenti “testuali” che raccontano l’agire medico. Il racconto evidenzia quanto sia importante passare dalla oggettività della lettura fisica del testo-paziente (the physical text e the instrumental text) alla soggettività della lettura esistenziale (the experential text e the narrative text) per avere una comprensione della causa della malattia. Il medico, protagonista del racconto di Cˇ echov, riuscirà a cogliere oltre il dato oggettivo, visivofattuale, della patologia (segnali della malattia) il significato soggettivo (segnali dell’anima) ponendosi in ascolto non solo della malattia ma della malata, superando il limitante rapporto I-It (relazione impersonale dell’esame clinico), per consentire quello più dedicato e compassionevole dell’I-Thou (relazione personale). I segnali dell’anima, spie di un disagio esistenziale che affonda le radici nel vissuto, diventano chiavi di accesso al testo esperienziale. ---------- The term narrative medicine, today recurring in medical literature, immediately recalls the importance of clinical history told by patients as an indispensable criterion for formulating the diagnosis and defining the appropriate therapy. From this point of view, the diagnostic iter is an hermeneutical action “of stories”, in some way similar to the reading of literature texts. Several articles published in international medical reviews refer to patient as a text, according to various meanings: the physical text, the physical signs of illness as they could objectively be examined; the experiential text, the existential experience of illness; the instrumental text, the laboratory data as well as the results of instrumental texts; the narrative text, the clinical history told by the patient. In this article, a story by Cˇ echov, Case History, is used to show various “textual” moments explaining medical acting. This story underlies the importance of passing from the objectivity of the physical reading of the textpatient (the physical text and the instrumental text) to the subjectivity of the existential reading (the experiential text and the narrative text) in order to understand the cause of illness. The doctor, protagonist of theCˇ echov’s story, will be able to seize besides the objective, visual-factual data of the pathology (signals of illness) the subjective meaning (signals of the soul), listening not only the illness but also the ill woman. He will overcome the IIt limiting relationship (impersonal relationship of clinical text) for allowing the more dedicated and pitiable I-Thou relationship (personal relationship). The signals of the soul, signs of an existential discomfort rooted in life, become the access keys to the experiential text.

Antimicrobial use in livestock production is a controversial subject. While antimicrobials should be used as little as possible, it is still necessary, from both an animal health and welfare point of view, to treat infected animals. The study presented here aimed to analyse antimicrobial use on Austrian dairy farms by calculating the number of Defined Course Doses (DCDvet) administered per cow and year for dry cow therapy. Antimicrobial use was analysed by production system and whether farmers stated that they used blanket dry cow therapy (i.e., all cows in the herd were treated) or selective dry cow therapy (i.e., only cows with a positive bacteriological culture or current/recent history of udder disease were treated). A statistically significant difference (p < 0.001) was determined between antimicrobial use for blanket (median DCDvet/cow/year: 0.88) and selective dry cow therapy (median DCDvet/cow/year: 0.41). The difference between antimicrobial use on conventional and organic farms for dry cow therapy as a whole, however, was not statistically significant (p = 0.22) (median DCDvet/cow/year: 0.68 for conventional; 0.53 for organic farms). This analysis demonstrates that selective dry cow therapy leads to a lower overall use of antimicrobials and can assist in a more prudent use of antimicrobials on dairy farms.

From a clinical point of view, oxidative stress (OS) is considered the primary cause of numerous metabolic processes intransition cow.Thus, the addition of antioxidants has been considered a palliative or preventive treatment. But beyond the clinical perspective, antioxidant supplementation provides an added value to the product obtained being either milk or meat. This paper reviews the beneficial aspects that provide antioxidant supplementation on quality of both products and that fit into the new concept that the consumer has a functional and healthy food. Our approach is from a veterinary standpoint, by reviewing the studies conducted to date and the new perspectives that are interesting and need to be studied in the following years. One of the highlights is that sustainable farming, one in which production is combined with animal health, also impacts positively on the quality of the final products, with beneficial antioxidant properties to human health.

The development of new acaricides is a long and very expensive process. Worryingly, there is increasing resistance to available acaricides worldwide leading to the real possibility that our dwindling supply of effective acaricides will be exhausted unless action is taken to increase the number of new acaricidal products and reduce the rate of resistance development. In 1995, eight major animal health pharmaceutical companies formed the Veterinary Parasite Resistance Group (VPRG) to act as an expert consultative group to guide the FAO in resistance management and collaborate in the prudent use of acaricides. In this paper, members of the VPRG discuss the problems and processes in acaricide development, resistance in the field to commonly used acaricides and the different considerations when targeting the cattle and pet market, and give their view of the future for tick control from the perspective of the animal health industry.

Background: Kissing nevus is a congenital nevus in adjacent parts of the eyelids. Malignant transformation of kissing or divided nevi of the eyelids is rarely described. Objective: To report a very rare case of malignant transformation of kissing nevus with ocular and extraocular spread. Case: A 57- year- old man with 6/6 visual acuity in both eyes presented with a kissing nevus present since birth in right upper and lower eyelids which had a slow growth phase. The upper lid in the area of the nevus was thickened with a 20x12x15 mm black pigmented crusted hemorrhagic nodular lesions. The lower lid had a 6 mm black pigmented ulcerated lesion over the pre-existing nevus in the lateral third of the lid with full thickness infiltration. Another 5x4 mm pigmented lesion over the lower medial lid margin with a thickness of about 3 mm extended to the conjunctival side of the lower lid. Right sided pre-auricular and submaxillary nodes were palpable. A biopsy of tissue samples from the eyelid and pre-auricular nodes were consistent with malignant melanoma.Conclusion: Malignant transformation of kissing nevus is rare. It can spread to the conjunctiva, pre-auricular and sub-mandibular lymphnodes.DOI: http://dx.doi.org/10.3126/nepjoph.v4i2.6555 Nepal J Ophthalmol 2012; 4 (2): 329-332
