Objective. Estimation of expediency for peritonization of the stapler resection line, aiming to prevent the stapler suture hemorrhage and insufficiency. Маterials and methods. The investigation was conducted on laboratory rabbits, to which the sleeve gastric resection was performed: in 9 experimental animals (Group 1) – with peritonization of the stapler suture line, in experimental animals (Group 2) – without peritonization. Structural changes of gastric wall in the stapler suture portion in both groups of experimental animals were investigated. Results. Peritonization of the stapler suture line have caused exaggeration of the gastric walls ischemic changes. Conclusion. Peritonization of the sleeve gastric resection line promotes prophylaxis of postoperative hemorrhage from the stapler suture, but do not prevent its insufficiency.

ContextThe occurrence of severe dysphagia after laparoscopic total fundoplication is currently an important factor associated with loss of quality of life in patients undergoing this modality of treatment for gastroesophageal reflux disease.ObjectivesCompare the incidence and evaluate the causes of severe postoperative dysphagia in patients undergoing laparoscopic total fundoplication (LTF) without short gastric vessels division, using the anterior gastric wall (Rossetti LTF) or anterior and posterior gastric walls (Nissen LTF).MethodsAnalysis of the data of 289 patients submitted to LTF without short gastric vessels division from January 2004 to January 2012, with a minimum follow-up of 6 months. Patients were divided in Group 1 (Rossetti LTF – n = 160) and Group 2 (Nissen LTF – n = 129).ResultsThe overall incidence of severe postoperative dysphagia was 3.11% (4.37% in group 1 and 1.55% in group 2; P = 0.169). The need for surgical treatment of dysphagia was 2.5% in group 1 and 0.78% in group 2 (= 0.264). Distortions of the fundoplication were identified as possible causes of the dysphagia in all patients taken to redo fundoplication after Rossetti LTF. No wrap distortion was seen in redo fundoplication after Nissen LTF.ConclusionsThe overall incidence of severe postoperative dysphagia did not differ on the reported techniques. Only Rossetti LTF was associated with structural distortion of the fundoplication that could justify the dysphagia.

The metabolic and immunological indicators were determined in the blood of laying hens of ISA BROWN hybrid divided into three groups, the control group and two experimental groups. The administration of n-3 polyunsaturated fatty acids (PUFA) in the form of linseed (Group 1) and fish oil (Group 2) and α-tocopherol as antioxidant to laying hens resulted in a significant increase in concentrations of high density lipoproteins (HDL) cholesterol (P < 0.05), eicosapentaenoic (EPA), docosahexaenoic (DHA) and α-linolenic acids (AA) in blood in comparison to the control group. Significantly lower levels of cholesterol (CHOL) were determined in both experimental groups at the third sampling (P < 0.05) and arachidonic acid (AA) in the fish group (P < 0.01). The metabolic activity of phagocytes and polyclonal activation of lymphocytes showed no significant differences and remained within the physiological range. Oral administration of n-3 PUFA showed no significant increase of the immune response of experimental animals.

Background: Laparoscopic sleeve gastrectomy (LSG) is a procedure frequently used to treat morbid obesity, due to its simplicity compared to other bariatric techniques. However, LSG can lead to serious complications, such as gastric leakage and bleeding from the staple line. To reduce these complications, seroserosal reinforcement of the mechanical suture line after gastrectomy is generally recommended. In recent decades, studies have focused on the safety of anastomosis with staples, especially compared to manual sewing techniques. Since studies on the improvement of stapling technology are limited, this study arises to compare the clinical results of staple line oversewing versus stapling technology with triple-row and enhanced staple configurations in laparoscopic sleeve gastrectomy.Methods: A retrospective review from a prospectively maintained database of 124 laparoscopic vertical gastrectomies performed at single centre between March 2010 and December 2016. Patients were divided into two groups, with comparable anthropometric parameters and inclusion criteria. Seroserosal reinforcement was used in the first group, and stapling technology with triple-row and enhanced staple configurations in the second. Rates of anastomotic leakage, bleeding, reoperation, and 30-day mortality were compared.Results: In Group 1 the average surgical time was 125 min, whereas in Group 2 it was 87 min. No differences were found between the two groups regarding leakage or bleeding of the staple line.Conclusions: The use of triple-row stapling devices during laparoscopic vertical gastrectomy enables surgical time to be reduced. Further high-quality studies to evaluate the efficacy and effectiveness of stapling technology with triple-row and enhanced staple configurations are needed.

ObjectRecombinant human bone morphogenetic proteins (rhBMPs) are FDA-approved for specific spinal fusion procedures, but their use is contraindicated in spine tumor resection beds because of an unclear interaction between tumor tissue and such growth factors. Interestingly, a number of studies have suggested that BMPs may slow the growth of adenocarcinomas in vitro, and these lesions represent the majority of bony spine tumors. In this study, the authors hypothesized that rhBMP-2 placed in an intraosseous spine tumor in the rat could suppress tumor and delay the onset of paresis in such animals.MethodsTwenty-six female nude athymic rats were randomized into an experimental group (Group 1) or a positive control group (Group 2). Group 1 (tumor + 15 μg rhBMP-2 sponge,13 rats) underwent transperitoneal exposure and implantation of breast adenocarcinoma (CRL-1666) into the L-6 spine segment, followed by the implantation of a bovine collagen sponge impregnated with 15 μg of rhBMP-2. Group 2 (tumor + 0.9% NaCl sponge, 13 rats) underwent transperitoneal exposure and tumor implantation in the lumbar spine but no local treatment with rhBMP-2. An additional 8 animals were randomized into 2 negative control groups (Groups 3 and 4). Group 3 (15 μg rhBMP-2 sponge, 4 rats) and Group 4 (0.9% NaCl sponge, 4 rats) underwent transperitoneal exposure of the lumbar spine along with the implantation of rhBMP-2– and saline-impregnated bovine collagen sponges, respectively. Neither of the negative control groups was implanted with tumor. The Basso-Beattie-Bresnahan (BBB) scale was used to monitor daily motor function regression and the time to paresis (BBB score ≤ 7).ResultsIn comparison with the positive control animals (Group 2), the experimental animals (Group 1) had statistically significant longer mean (25.8 ± 12.2 vs 13 ± 1.4 days, p ≤ 0.001) and median (20 vs 13 days) times to paresis. In addition, the median survival time was significantly longer in the experimental animals (20 vs 13.5 days, p ≤ 0.0001). Histopathological analysis demonstrated bone growth and tumor inhibition in the experimental animals, whereas bone destruction and cord compression were observed in the positive control animals. Neither of the negative control groups (Groups 3 and 4) demonstrated any evidence of neurological deterioration, morbidity, or cord compromise on either gross or histological analysis.ConclusionsThis study shows that the local administration of rhBMP-2 (15 μg, 10 μl of 1.5-mg/ml solution) in a rat spine tumor model of breast cancer not only fails to stimulate local tumor growth, but also decreases local tumor growth and delays the onset of paresis in rats. This preclinical experiment is the first to show that the local placement of rhBMP-2 in a spine tumor bed may slow tumor progression and delay associated neurological decline.

The most common comorbid pathology in children with asthma is gastroesophageal reflux disease (GERD) associated with reflux esophagitis (RE), which ranges from 32 % to 80 %. Histological changes of the esophageal mucosa in RE have been described in adults and children, but there are only isolated studies that describe the morphological features of the esophageal mucosa in combined pathology, taking into account the severity of asthma. The aim is to study the histological and immunohistochemical features of the esophageal mucosa in children with asthma combined with reflux esophagitis. Materials and methods. In 43 children aged 6–17 years with RE and severe asthma (group 1), with mild/moderate asthma (group 2) and without asthma (group 3), mucosal biopsies from the distal and proximal esophagus were examined by histolo­gical and immunohistochemical methods. Immunohistochemical research was performed in serial paraffin sections according to standard protocols using monoclonal antibodies to Ki-67, MMP-9, VEGF, BCL-2, IgE and CD68. Results. In children with asthma combined with RE, the structural changes of the esophageal mucosa differed depending on the severity of asthma. Severe basal epithelial hyperplasia was registered in 92.31 % of children in group 1, and its frequency was significantly different from children in groups 2 and 3. A characteristic feature of children with asthma and reflux eso­phagitis was dyschronosis, which was characterized by foci of hypo- and hypertrophy of basal layer cells (92.31 % of children in group 1 and 37.50 % of children in group 2). Severe elongation of the “papillae” was found only in 38.46 % of children in group 1. Immunohistochemical features of the esophageal mucosa of children with asthma and reflux esophagitis revealed the expression of Ki-67 antigen, IgE and a weak macrophage response (CD68), the severity of which differed from children with reflux esophagitis without asthma. Conclusions. Morphological changes in the esophageal mucosa of children with reflux esophagitis and asthma differ from children with reflux esophagitis without asthma in the presence of severe epithelial damage, dyschronosis of changes, severe elongation of the “papillae”, pronounced cell proliferation (Ki-67) and local IgE expression.

Background. Inflammation of the hip joints in ankylosing spondylitis (AS) is a frequent and severe manifestation of the disease, which in 7–8 % of patients is accompanied by the requirements of hip joints prosthesis. In the treatment of hip arthritis associated with AS non-steroidal anti-inflammatory drugs (NSAIDs), sulfasalazine (SSZ) and tumor necrosis factor-alpha blockers were used. However, the influence of these treatment on the dynamics of structural changes in hip joints is not studied.Purpose. To evaluate the dynamics of clinical, radiologic and ultrasonographic indices of hip joints in patients with AS who take different treatment methods for 12 months: NSAIDs, SSZ and adalimumab (ADA).Materials and methods. Dynamic monitoring of 78 patients with AS (corresponding to the New York modified criteria of 1984), who also had clinical, ultrasonographic and radiographic signs of inflammation of hip joints. The patients were divided into three groups: patients of the group 1 (n = 25) were been receiving NSAIDs; patients of group 2 (n = 26) had started to take SSZ (2–3 grams per day) on background of NSAIDs; patients of group 3 (n = 27) were started to take ADA (subcutaneously, 40 mg once every 2 weeks) on the background of NSAID. In addition to the generally accepted clinical and laboratory studies, all patients were being underwent by X-ray examination with an evaluation of the BASRI-Hip index and ultrasonography of hip joints during 12 months of follow-up.Results and discussion. In patients of group 2 treatment with SSZ during 12 months had been resulted in a decrease in the severity of pain from the visual analogue scale (VAS) at hip joint motion (26.1 [13.9, 42.7] vs 69.3 [56.8, 79, 3]), CRP (4.4 [1.5, 6.9] mg/L vs 15.2 [8.3, 21.8] mg/L) and a decrease in the thickness of the hip synovial membrane (6.7 [5.8, 8.5] mm vs 9.6 [7.9, 11.8] mm) compared with the initial data. In patients of the group 3 treatment with ADA had been lead to decreasing of pain VAS (14.2 [5.2, 26.7], vs. 72.1 [65.3, 89.1], BASDAI and ASDASCRP (1.7 [1.1, 3.1] and 1.4 [1.1, 2.2] vs. 7.5 [5.9, 8.6] and 3.1 [2.6, 3.9]), CRP (2.7 [0.2, 5.8] mg/L vs. 24.3 [17.4, 35.9]) and decrease in the thickness of hip synovial membrane (6.3 [5.0, 7.7] mm vs. 9.9 [8.1, 12.6] mm) and an increase of the thickness of the hyaline cartilage covering the head of the femur in comparison with group 1 (0.15 [0.09; 0.22] mm vs. —0.08 [–0.12, —0.04] mm). The effect of both drugs on the dynamics of the radiographic index BASRI-Hip and the formation of new osteophytes in hip joints was not noted.Conclusion. Inclusion of SSZ and ADA in a complex of treatment of patients with hip arthritis associated with AS leads to a decrease of synovitis of hip joints. Usage of ADA is accompanies by ultrasonographic signs of the restoration of hip joints cartilage.

Objective. To review retrospectively the electrophysiological and structural changes in 13 Chinese patients with Leber hereditary optic neuropathy (LHON). Methods. 26 eyes of 13 patients with a genetically confirmed diagnosis of LHON were categorized into two groups according to the duration of the disease: group 1 (duration less than 3 months) and group 2 (duration between 3 months and 18 years). Clinical history, comprehensive visual electrophysiology, optical coherence tomography (OCT), and color fundus photography were performed. Results. Fundoscopy showed optic disc hyperemia in group 1 and optic atrophy in group 2. OCT measures of retinal nerve fiber layer (RNFL) thickness around the optic disc and surrounding macula were normal in group 1 but reduced in group 2 (10 of 10 eyes). The thickness of the retinal ganglion cell layer (GCL) plus inner plexiform layer (IPL) surrounding the macula reduced significantly in group 1 and group 2 compared with a healthy control group. Pattern ERG (PERG) P50 amplitude was normal, but the N95/P50 ratio reduced in most of group 1 (4 of 5 eyes) and in all of group 2 (11 eyes). PERG P50 peak time was abnormally short in group 2. Multifocal electroretinography (mfERG) showed subnormal responses associated with ring 1 (the central area) and ring 2 in group 1 and reductions in rings 1, 2, and 3 in group 2. Conclusion. The study highlights differences in retinal structure and function between the acute and chronic stages of LHON in a group of Chinese patients. There is PERG evidence of retinal ganglion cell dysfunction and OCT evidence of GCL + IPL thinning in both groups, but there is additional peripapillary RNFL loss in the chronic stage, associated with more severe RGC dysfunction. There is multifocal ERG evidence of localized macular dysfunction in both acute and chronic groups. The study highlights the importance of comprehensive electrophysiological and structural assessments of the retina in LHON and is pertinent to studies that aim to monitor disease progression or the effects of future therapeutic interventions.

Abstract Background We identify cognitive impairment and MRI structural brain changes in long-term oligodendroglial tumor survivors treated with radiation therapy (RT) alone (21%) or with chemotherapy (CT) (79%). Methods Oligodendroglial tumor patients (based on the World Health Organization [WHO] 2007 classification) who completed RT ± CT at least 2 years before the study initiation, were classified into 3 groups according to the time treatment was completed: Group 1 = 2–5 years (n = 22), Group 2 = 6–10 years (n = 13), and Group 3 >10 years (n = 13). All patients had a cross-sectional neuropsychological evaluation (n = 48) and a longitudinal volumetric analysis (gray matter [GM; n = 34]) between postsurgical and last follow-up MRI. White matter (WM) changes on MRI were assessed using a qualitative scale. Results There were no differences regarding tumor or treatment-related characteristics between groups. Six of 22 patients (27.3%) in Group 1; 5/13 (38.5%) in Group 2; and 9/13 (69.2%) in Group 3 had cognitive impairment that was considered severe in 3/22 patients (13.6%) in Group 1; 4/13 (30.8%) in Group 2; and 6/13 (46.2%) in Group 3. Patients in Groups 2 and 3 showed significant GM atrophy and more leukoencephalopathy than Group 1. Cognitive deficits were associated with brain atrophy and WM changes. Conclusions Long-term oligodendroglial tumor survivors who underwent standard RT ± CT treatment, mainly >5 years of its completion, present cognitive impairment, especially on memory and executive functions, associated with late GM and WM damage, thus highlighting the need of developing future strategies in patients with oligodendroglial tumor and long expected survival.

<b><i>Objective:</i></b> The aim of the study was to evaluate the association of conductive hearing loss (CHL) with the structural changes in the organ of Corti. <b><i>Methods:</i></b> Twenty ears of 10 healthy adult Wistar albino rats were included in the study. The right ears (<i>n</i> = 10) of the animals served as controls (group 1), and no surgical intervention was performed in these ears. A tympanic membrane perforation without annulus removal was performed under operative microscope on the left ears (<i>n</i> = 5) in 5 of 10 animals (group 2). A tympanic membrane perforation with annulus removal was performed under operative microscope on the left ears (<i>n</i> = 5) of the remaining 5 animals (group 3). Auditory brainstem response testing was performed in the animals before the interventions. After 3 months, the animals were sacrificed, their temporal bones were removed, and inner ears were investigated using scanning electron microscopy (SEM). The organ of Corti was evaluated from the cochlear base to apex in the modiolar axis, and the parameters were scored semiquantitatively. <b><i>Results:</i></b> In group 1, the pre- and post-intervention hearing thresholds were similar (<i>p</i> &#x3e; 0.05). In group 2, a hearing decrease of at least 5 dB was encountered in all test frequencies (<i>p</i> &#x3e; 0.05). In group 3, at the frequency range of 2–32 kHz, there was a significant hearing loss after 3 months (<i>p</i> &#x3c; 0.01). After 3 months, the hearing thresholds in group 2 and 3 were higher than group 1 (<i>p</i> &#x3c; 0.01). The hearing threshold in group 3 was higher than group 2 (<i>p</i> &#x3c; 0.01). On SEM evaluation, the general cell morphology and stereocilia of the outer hair cells were preserved in all segments of the cochlea in group 1 with a mean SEM score of 0.2. There was segmental degeneration in the general cell morphology and outer hair cells in group 2 with a mean SEM score of 2.2. There was widespread degeneration in the general cell morphology and outer hair cells in group 3 with a mean SEM score of 3.2. The SEM scores of group 2 and 3 were significantly higher than group 1 (<i>p</i> &#x3c; 0.05). The SEM scores of group 3 were significantly higher than group 2 (<i>p</i> &#x3c; 0.05). <b><i>Conclusion:</i></b> CHL may be associated with an inner ear damage. The severity of damage appears to be associated with severity and duration of CHL. Early correction of CHL is advocated in order to reverse or prevent progression of the inner ear damage, which will enhance the success rates of hearing restoration surgeries. Subjective differences and compliance of the hearing aid users may be due to the impact of CHL on inner ear structures.

The aim of the present study was to investigate the distribution of the glycoconjugates sialoderivatives in the human testis. Orchidectomy specimens from men aged 18–30 years (Group 1) and from men aged 70–93 years (Group 2) were obtained at autopsy. The study was performed using digoxigenin-labelled lectins, namely Maackia amurensis II lectin (MAA), Sambucus nigra agglutinin (SNA) and Arachis hypogaea lectin (PNA), in addition to enzymatic and chemical treatments (neuraminidase, KOH–neuraminidase, mild oxidation–neuraminidase, mild oxidation–KOH–neuraminidase, strong oxidation–neuraminidase, strong oxidation–KOH–neuraminidase), to characterise the different glycosidic linkages of the sialoderivatives and to obtain information regarding their structure. In all Group 2 samples, sialic acids linked α-2,3 to galactose and α-2,6 to galactose/N-acetyl-d-galactosamine (Gal/GalNAc), revealed by MAA and SNA, respectively, were observed in testicular interstitial tissue and in the lamina propria. Sialic acid linked α-2,6 to Gal/GalNAc was detected in only some samples from Group 1. After treatment, PNA showed structural changes and/or the gradual disappearance of sialic acid linked to d-galactose-β(1–3)-N-acetyl-d-galactosamine in testicular components with aging. These findings indicate that changes in the metabolism of sialoderivatives in the testis could be related to morphofunctional changes in various testicular components typical of this organ during aging. This suggests that sialoderivatives are important in the functionality of the mature testis in men, as well as its involution.
