Determination of serum adenosine deaminase and xanthine oxidase activity in Kangal dogs with maternal cannibalism.

AIM: Kangal dogs, known as guard dogs in many countries of the world, have been found to eat their own puppies during their first 24 h following birth, which is called as maternal cannibalism. Adenosine deaminase (ADA) and xanthine oxidase (XO) are important enzymes for purine metabolism. In this study, the aim is to evaluate ADA and XO activities in Kangal dogs with maternal cannibalism. MATERIALS AND METHODS: The material of the study consists of the blood sera of Kangal dog breed with and without maternal cannibalism in the breeders around Sivas city and its districts. ADA and XO activities in blood serum of these animals were investigated by spectrophotometric method. RESULTS: ADA activities in Kangal dogs with maternal cannibalism were increased to the control group without maternal cannibalism (p<0.01). CONCLUSION: Postnatal measurement of ADA activity in dogs may be useful in assessing maternal cannibalism.

Vertebral metastases from intracranial meningioma.

Meningioma rarely gives rise to metastases outside the brain and meninges. We report here a case of a patient who was treated for anaplastic brain meningioma with surgery and fractionated radiation therapy without any recurrence until 5 years after the operation, when she developed vertebral metastases.

[Intraorbital dermoid cyst. Case report and review of the literature]. / Kyste dermoïde intraorbitaire. À propos d'une observation et revue de la littérature.

Periorbital dermoid cysts are benign tumors most often seen in young children. Intraorbital location, though rare, should not be overlooked. Good quality imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures, as well as in planning the surgical approach. The authors report a case of a 46-year-old male with an intraorbital dermoid cyst presenting with progressive left proptosis. Appearance on imaging (CT and MRI) was consistent with intraorbital dermoid cyst. The tumor was extirpated. Histopathologic examination confirmed the diagnosis of dermoid cyst. We also present a review of the literature.

The importance of myeloperoxidase enzyme activity in the pathogenesis of Crimean-Congo haemorrhagic fever.

Crimean-Congo haemorrhagic fever (CCHF) is a disease with a severe course including acute viral haemorrhagic fever, ecchymosis, thrombocytopenia, hepatic function disorder and high mortality. Myeloperoxidase (MPO) is an enzyme located in neutrophil granulocytes and plays an important role in the destruction of phagocytosed micro-organisms. The aim of this study was to analyse MPO enzyme activity in CCHF cases compared with a control group. A total of 47 randomly selected CCHF patients admitted to the Department of Infectious Diseases of Cumhuriyet University Hospital in Sivas, Turkey, were studied, and as a control group, 41 age- and sex-matched individuals without any systemic disease were included in this study. MPO enzyme activity was measured in plasma and leukocytes for both groups by the ELISA method. MPO plasma and MPO leukocyte values were calculated as 57.62 ± 8.85 and 44.84 ± 9.71 in CCHF patients, and 0.79 ± 0.29 and 0.49 ± 0.11 in the controls, respectively. MPO enzyme activity was statistically significantly higher in patients with CCHF when compared to the control group. In conclusion, MPO enzyme activity is directly related to the activation of phagocytic leukocytes, and increases in both the plasma and leukocytes in CCHF patients. The increase of the MPO enzyme activity in leukocytes due to viral load leads to the destruction of the leukocyte. It is thought that MPO enzyme activity in plasma was higher in CCHF patients due to the destruction of leukocytes. MPO enzyme activity may be important in terms of the prognosis in patients with CCHF; however, more extensive studies are required on this subject.

[Nasofrontal fistula and epidermoid cyst: a case study]. / Fistule et kyste épidermoïde naso-frontaux: à propos d'une observation.

Nasofrontal fistulas, also called nasofrontal dermal sinuses, are very rare and found for the most part in children. This congenital malformation may be revealed by local infection or neuromeningitis, making this a serious disorder. We report one case of nasofrontal dermal sinus diagnosed in an 11-month-old girl, which was complicated by left fronto-orbital infection. Through this case, the authors stress the role of imaging methods in confirming the diagnosis and looking for associated cysts (dermoid and epidermoid).

[Diagnosis of spinal diseases by MRI]. / Irm et rachis.

For a long time the imaging diagnosis of spine disease was based on conventional radiology (plain radiography, myelography and arteriography). The recent employment of MRI had changed the study of spine disease thanks to an excellent contrast and a multiplanar approache. In fact, nowadays MRI is the most sensible technic for a combined study of spine container and contents and medullar tissue.

[Primitive pleural hydatid cyst: case report]. / Kyste hydatique pleural primitif: a propos d'une observation.

Even in endemic countries, the primitive pleural hydatid cyst is exceptionnal and it's very difficult to distinguish from other pleural and parietal cystic masses all the more the immunologic tests are negative. We report the case of a primitive pleural hydatid cyst diagnosed in 43 years old man. Throug this case, imaging features are emphasized.

[Adrenal gland hemangioma: a case report]. / Hémangiome surrénalien: à propos d'un cas.

Hemangioma is a benign vascular tumor composed of angioblastic cells. The adrenal gland localization is very rare, with only fifty cases reported in literature. We report a case of adrenal gland hemangioma diagnosed in a 55-year-old woman who presented a cervical neoplasm. The non-specific imaging features, the tumor size and the clinical context led to mandatory surgical resection. The pathological examination established the diagnosis of adrenal gland hemangioma.

[MRI and pituitary adenoma]. / IRM et adénomes hypophysaires.

Pituitary is the most important gland of the organism which can be affected by many diseases, especially by adenomatous processes. Classically macroadenoma, microadenoma and picoadenoma are described, according to the size of the pituitary adenoma. The diagnosis of microadenoma was long considered a highly difficult task and that of picoadenoma was impossible by computed tomography. Recently, the high resolution of multiplanar MRI has enabled the diagnosis of microadenomas measuring less than 3 mm (picoadenoma). For macroadenoma, MRI not only contributes to diagnosis but is particularly important to assess the extension and to detect possible complications. The aim of our study is to illustrate MRI features in pituitary adenoma.

[Cavernous hemangioma of the breast: a case report]. / Hémangiome caverneux du sein: à propos d'un cas.

Cavernous hemangiomas of the breast are uncommon. Clinical diagnosis is rather difficult. Generally there are coincidental microscopic findings. We present a case of a 67-year-old woman which commenced as a 6 cm palpable mass of the right breast. The use of mammography, ultrasound and MRI facilitate diagnosis. Large surgical excision of the lesion was performed and histology allowed to find a cavernous hemangioma without cellular atypia.

[Pterygoïdien hydatid cyst]. / L'hydatidose ptérygoïdienne.

INTRODUCTION: The cervico-facial hydatid cyst is rare. It accounts for 1% echinococcisis locations and usually involves the salivary gland and the thyroid. Pterygoid muscle involvement is exceptional. CASE REPORT: We report the case of a patient presenting a hydatid cyst of the pterygoid muscle. The patient presented a non specific progressive tumor syndrome. DISCUSSION: This case illustrates the importance of CT scans. Surgery is always required. We emphasize the risk of complications when the diagnosis is missed.

[Solitary eosinophilic granuloma of the orbit: a case report]. / Granulome éosinophile isolé de l'orbite. A propos d'un cas.

The authors report a case of eosinophilic granuloma involving the roof and the lateral wall of the left orbit in a 5-year-old boy. The clinical presentation and especially the imaging features (computed tomography and MRI) suggested a malignant tumor and the final diagnosis was obtained by fine needle aspiration biopsy with histopathologic examination. Despite its alarming radiologic appearance, there was spontaneous healing of the eosinophilic granuloma with restitution ad-integrum of the bone.

[Neurosarcoidosis as the first manifestation of sarcoidosis: diagnosis difficulty. A case report]. / Problème diagnostique d'une neurosarcoïdose révélatrice. A propos d'un cas.

Clinically apparent involvement of the nervous system occurs in a relatively small number of patients with sarcoidosis. The diagnosis of neurosarcoidosis is often difficult and particularly in patients who lack either pulmonary or systemic manifestations of sarcoidosis. Furthermore clinical and imaging features of neurosarcoidosis are extremely variable. We report a case of neurosarcoidosis which had been considered and treated at first as tuberculosis. Only the occurrence, two years later, of pulmonary manifestations of sarcoidosis enabled the diagnosis.

[Right tracheal bronchus associated with tuberculosis pneumonia. A case report]. / Bronche trachéale droite associée à une lobite segmentaire tuberculeuse. A propos d'un cas.

Right tracheal bronchus is a rare almost always asymptotic congenital malformation. We report a case of right tracheal bronchus associated with pneumonia tuberculosis of the apical segment of the upper right lobe. We describe the characteristic of this malformation and stress the role of computed tomography scan to detect these anomalies.
