Abstract A two-year old Jack Russell Terrier female with left-sided epistaxis was brought to the Clinic of the Bucharest Faculty of Veterinary Medicine. Endoscopy of the left nasal cavity revealed a cauliflower-like mass. Cytological and histopathological features were specific to canine transmissible venereal tumour (CTVT). Tumor tissue showed positive immunoreactivity to anti-vimentin monoclonal antibody (90%) and Ki67 (35%) and samples were negative for anti-cytokeratin monoclonal antibody. Chemotherapy with vincristine sulphate at a dose of 0.025 mg/kg i.v./week for 6 administrations was successful. This paper presents a primary form of nasal CTVT in a Jack Russell Terrier female.

Transmissible Venereal Tumour

Background: Canine transmissible venereal tumour (CTVT) also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is usually transmitted through coitus and mainly affects the external genitalia of young sexually matured dogs. Surgery, chemotherapy, radiotherapy and immunotherapy are considered as effective treatment protocols. Therefore, depending upon the availability present study was designed to investigate the efficacy of different surgico-chemotherapeutic protocols for treatment of canine transmissible venereal tumour.Methods: The study was conducted during January 2018 to July 2018 at the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology, College of Veterinary Science and A.H., Anjora, Durg (C.G.) on 18 canines of various breed, irrespective of age, sex and divided into three groups consisting 6 animals in each group. Group A was treated with surgical excision of tumour only where as Group B and Group C were treated with surgical excision of tumour followed by administration of Doxorubicin (30mg/m2) BSA and Vincristine sulphate (0.025 mg/kg) intravenously alongwith DNS at 7th and 14th post-operative days respectively. Different physiological and haemato-biochemical parameters (Hb, PCV, TLC, TPC, DLC, serum glucose, TSP, SUN, SC, ALT, AST and ALP) were recorded preoperatively, postoperatively and after chemotherapy at 10th, 30th and 60th days intervals.Result: The present investigation showed transient changes in physiological and haemato-biochemical parameters before, post surgery and post chemotherapeutic management and was within normal range. Histopathological examination revealed confluent sheet of tumour cells arranged in large round oval or polyhedral shaped distributed in tight clusters or cords. Group A showed mild to moderated reoccurrence while Group B showed minimum reoccurrence. Group C showed no reoccurrence. Thus, surgery combined with vincristine therapy is most effective for treating dogs suffering with transmissible venereal tumour.

Transmissible Venereal Tumour

Canine transmissible venereal tumour (CTVT) is a neoplasia naturally transmitted in susceptible dogs through coitus. CTVT has a worldwide distribution, with a high prevalence in tropical and sub-tropical urban environments. The study aimed at evaluating CTVT lesions in local breeds of dogs and to assess morphological changes based on sex before and after administration of vincristine sulphate. Clinical and gross morphology, fine needle aspirates cytology (FNAC) and routine histopathology methods were used. Two FNAC and histopathological microscopic slide sections from each of the seven sampled dogs were stained with Giemsa stain and Hematoxylin and Eosin. All dogs were treated with vincristine once weekly over a six weeks period after which clinical morphological and histopathological changes were assessed. Grossly, before treatment the tumour masses appeared irregular, cauliflower like with tendency to bleed, sizes ranged from ≥5cm to ≤2cm with or without metastasis to regional lymph nodes. Cytologically, the tumours had homogenous, sheet-like cellular mass. Cytoplasm with punctate vacuoles, anisokaryosis with anisonucleoliosis and coarse to reticulate nuclear chromatin were seen. Lymphocytoid cell pattern was dominant cell type. Histopathology showed sheets of round cells with nuclear and cytoplasmic variations. Histopathology of the treated dog revealed hyper-cellularity, absence of nucleoli, prominent mitotic figures, reduced cell size and presence of inflammatory cells. There was no difference on the cellular changes after vincristine treatment between female and male dogs. Cytology and histopathology showed that vincristine sulphate suppresses the development of tumour through alteration of cellular morphology with no difference between male and female dogs.

A 2-year-old mare of an unknown breed was referred to the clinic due to undetermined breathing difficulties. Physical examination revealed painless swelling rostral to the nasoincisive notch and a large, firm mass protruding from the left nostril. Radiographic examination of the head revealed a mass occupying the left nasal cavity and a displaced and hypoplastic last premolar of the left maxilla. The CT scan showed a well-demarcated heterogeneous mass measuring 22 × 9 × 5 cm (length × height × width) in the left nasal cavity attached to the roots of the displaced tooth and conchae. The surgery was performed on the standing horse. Firstly, due to the oblique position of the displaced tooth, the extraction was performed extra-orally through the trephination and repulsion of the maxillary bone. In the next step, a direct surgical approach was chosen for the caudal part of the mass via the osteotomy of the left nasal bone. The mass was bluntly separated from the conchae and removed through the nostril using Fergusson forceps. The histopathological characteristics of the mass led to the diagnosis of ossifying fibroma. The horse recovered completely in seven months, without recurrence after two years.

AbstractObjective:This study compared the results of nasal Staphylococcus aureus carriage and nasal cytology in men with and without a moustache.Methods:The study group comprised 118 adult men with a moustache, and the control group consisted of 123 adult men without a moustache. Samples were taken from the participants' right nasal cavity for cytology and from the left nasal cavity for microbiology.Results:The results for S aureus were positive in 19.5 per cent (n = 23) of participants with a moustache and in 20.3 per cent (n = 25) of men without a moustache. This difference was not significant (p > 0.05). However, nasal cytology revealed rich eosinophil clusters in participants with a moustache.Conclusion:The presence or absence of a moustache had no effect on nasal S aureus colonisation. However, further research is needed to understand whether the presence of a moustache increases the risk of allergic or non-allergic rhinitis.

Abstract- Nasal foreign bodies are usually received in otolaryngology practice. Although more frequently seen in pediatric patients, also they can affect adults, specifically those with mental retardation or any psychiatric problems. We presented an unusual case of the nasal foreign body, an eraser rhinolith in a 17-year-old boy with mild mental retardation presented with long-lasting nasal obstruction but no chronic infection or epistaxis. Computed tomography revealed a peripherally calcified sub-mucosal round mass in the left nasal cavity. After surgery, a round shape foreign body that looked like an eraser piece was removed from the nasal cavity. Rhinolith can present just with nasal obstruction. With properly diagnosed and appropriate surgery, all rhinoliths can be removed and complication of extraction can be minimized

Schwannomas are benign tumors arising from Schwann cells of myelinated nerve sheath. Schwannomas of the nasal cavity and paranasal sinuses are rare, with only 4% occurrence. We report a case of a 48-year-old lady who presented with 1-year history of progressively worsening left nasal blockage. Rigid nasoendoscopy showed a smooth, globular mass occupying the left nasal cavity. The mass arose from the left nasal septum and impinged on the anterior part of the middle turbinate posteriorly and inferior turbinate anteriorly. Computed tomography of the paranasal sinuses showed a 3.8 × 1.8 x 3.7- cm enhancing soft tissue density in the left nostril. The mass obliterated the left nasal cavity and caused deviation of the septum to the right. The patient underwent an endoscopic excision and histopathologic examination confirmed the diagnosis of Schwannoma. Postoperative recovery was uneventful and no recurrence was seen in the follow-up period. Bangladesh Journal of Medical Science Vol.18(3) 2019 p.660-662
