[Comparative analysis of enteral feeding practices for prevention of gastrointestinal complications in infants with ductus-dependent congenital heart diseases].

Mesenterial hypoperfusion is one of the main pathogenetic factors of necrotizing enterocolitis (NEC) in infants with ductus-dependent congenital heart diseases. NEC in infants undergoing congenital heart surgery increases mortality and length of hospital stay. NEC is also associated with adverse neurodevelopmental outcome. Optimization of enteral feeding can reduce the risk of gastrointestinal complications. NEC risk factors in infants with congenital heart are of special interest in the literature. This article discusses criteria for enteral feeding initiation and increasing preoperatively and after heart surgery. Enteral feeding protocols of leading cardiac surgical centers are reviewed. Practices to provide high energy and nutrient consumption in infants with congenital heart disease are described.

[Diagnostic possibilities of fine-needle aspiration biopsy in malignant tumors of the orbit]. / Diagnosticheskie vozmozhnosti tonkoigol'noi aspiratsionnoi biopsii pri zlokachestvennykh opukholiakh orbity.

Cytological studies were carried out in 94 patients with malignant tumors of the orbit using fine-needle aspiration biopsy. Diagnostic potentialities of the method are shown. The method possesses the highest diagnostic informative value in evaluation of the type of the process (98.8%). Cytological characteristics of the most incident malignant tumors of the orbit are presented.

[Intraocular malignant lymphoma]. / Vnutriglaznaia zlokachestvennaia limfoma.

The paper in devoted to a rare condition difficult to diagnose, intraocular lymphoma. Five patients with a disease history of 2 to 6 years were examined. The authors describe clinical features of the condition and histologic and electron microscopic findings. The clinical pattern of malignant intraocular lymphoma in polymorphous, therefore virtually every case with a sluggish uveitis or posterior scleritis resistant to common therapy has to be verified. A hematologist should take part in examination of such patients. Since the involvement is local, as our findings evidence, a course of polychemotherapy is necessary for such patients.

[Histological characteristics of ocular structures after YAG-laser exposure of various sections of the crystalline lens in experimental studies]. / Gistologicheskaia kharakteristika struktur glaza posle IAG-lazernogo vozdeistviia na razlichnye otdely khrustalika v éksperimente.

This work was aimed at analysis of all the aspects, pathomorphologic included, of short-pulsed YAG laser exposure of the lens. Experiments were carried out with 79 rabbit eyes. After laser exposure the eyes were enucleated in 1-24 h and in 7-10 days. Thirty-one eyes were subjected to YAG laser ++capsule puncture. Fragmentation of intracapsular structures was carried out in 23 eyes. Combined operations were performed on 25 eyes. Every series comprised two groups, differing by the energy of laser exposure: 3-5 mJ. Histologic analysis has lead the authors to the following conclusions. The pattern and severity of pathomorphologic changes were directly related to the energy and time of laser exposure and site of the focal plane of irradiation. The major destructive shifts after YAG laser fragmentation of the cortical layer and capsulotomy are focussed at the site of exposure and involve the adjacent sections of the lens. Laser exposure of 3-5 mJ may be used to open the anterior capsule of the lens and to facilitate the cataract mass discharge in extracapsular cataract extraction. Use of combined method helps enhance induration and fragmentation of the cortical layers of the lens, rules out surgical discission of the anterior capsule of the lens, and facilitates removal of the nucleus and wash out of the lens mass.
