[Long-term clinical results of surgical treatment in patients with salivary stone disease and ducts deformation of the parotid gland]. / Otdalennye rezul'taty operativnykh vmeshatel'stv u bol'nykh sliunnokamennoi bolezn'iu i protokovymi deformatsiiami okoloushnoi sliunnoi zhelezy.

The authors with the goal of postoperative dynamic control over the results of surgical treatment of patients previously operated for salivary stone disease and various ducts deformations of the parotid salivary glands examined 16 patients with an observation period up to 8 years. It was found that recurrent acute parotitis or recurrence of stone formation was observed in 100% of cases. The authors developed methods of surgical treatment leads to long-term clinical success with no recurrence of the disease.

[Treatment of significant parotid ducts deformities].

The paper summarizes authors experience in treatment of 14 patients with congenital parotid ducts deformities (megastenon type). The results showed reconstructive surgical treatment to be sufficiently effective in such cases. If restoration of parotid function is not possible one should consider interventions for secretion reduction and duct walls excision.

[Methods of individual retrospective physical dosimetry in the problem of estimation of consequences of accidental irradiation].

The overview of the results of development, verification and application of the methods of individual retrospective physical dosimetry among population of settlements contaminated with radionuclides, which suffered from irradiation as a result of the accident in Chernobyl NPP, and among the population located in the vicinity of the Semipalatinsk nuclear test site is presented in the paper. The estimations of sensitivity of the methods of physical retrospective dosimetry are shown. The data on individual doses among population, which was irradiated as a result of accidental irradiation are presented as well.

[Primary ectopic intraosseous meningioma associated with multiple meningioma in a patient with central neurofibromatosis].

We present a case of multiple meningiomas (MM) as initial manifestation of central neurofibromatosis (NF2). A 19 y. o. woman was admitted with increasing signs of spinal cord compression at Th5-7 level. At CT assisted myelography, an entirely extradurally situated meningioma was detected and totally removed. Two years later increasing right-sided exophthalmos, without visual impairment was observed. The CT scan revealed thickening and abnormal shape of the sphenoid and the bony structures of the orbit. The retrobulbar space was narrowed and the optic nerve was shifted. At operation, ala parva of the sphenoid bone, the roof and the lateral orbital wall appeared thickened, laminated, fragile and exceedingly vascularized. The subdural space was found intact. The histopathological study revealed primary intraosseous meningioma of the sphenoid. There was no family history for neurofibromatosis (NF). The clinical findings at this time could not fulfil the criteria for NF2 and the case was considered as "true" multiple meningiomas occurring in different compartments of the neuraxis. The cytogenetical examination demonstrated a deletion of the long arm of the chromosome 22: 46 XX, del 22 (q 11.2). She was followed up and five years after the initial symptoms asymptotic bilateral vestibular schwannomas were found at CT and MRI. These findings finally led to the diagnosis NF2. There are no specific features distinguishing true MM from those associated with NF2, but we recall the importance of such manifestations for this diagnosis. We have not found any comparable case with these features in the medical literature.
