Purpose. To prevent intraoperative complications during fixation of the IOL-intracapsular ring-capsule bag complex during femto-assisted phacoemulsification of cataract complicated by congenital lens ectopia (Marfan syndrome) using intraoperative OCT. Material and methods. 3 men (6 eyes), with a diagnosis of cataract complicated by congenital ectopia of the lens (Marfan syndrome). The age of patients ranged from 19 to 25 years. Cataract phacoemulsification (CFE) with femto support and hydrophobic IOL implantation was performed by all patients. Fixation of complex "IOL-intracapsular ring-capsule bag" in sulcus ciliaris was performed with the control of intraoperative OCT. Results. BCVA was 0.6-0.8 at the first day after the operation. According to ultrasound biomicroscopy (UBM), the IOL was in the capsule bag in a horizontal position in all cases. Any damage of the iris and ciliary body was not found. After 6 months, according to UBM, a stable horizontal position of the IOL and the consistency of suture fixation of the «intracapsular ring-capsule bag-IOL» complex was recorded in all patients. Conclusion. The use of intraoperative OCT allows to accurately determine the individual anatomical location of the sulcus ciliaris and provide visual control of the IOL suturing and the «intracapsular ring-capsule bag» complex in congenital lens tectopia, avoiding excessive trauma of the surrounding eye tissues, and also to ensure a stable horizontal position of the IOL in the postoperative period. Key words: intraoperative optical coherence tomography, femtoassisted cataract phacoemulsification, congenital lens ectopia.

AbstractFemoral tunnel malposition is the most common reason for failure of primary anterior cruciate ligament reconstruction. There are several methods to identify the anatomical location of femoral footprint. Femoral offset aimer technique is one such technique which is easy to use and reliable. It is an ideal technique for junior and inexperienced surgeons to recreate the femoral tunnel in its anatomical footprint. The senior author (P.E.) has been using this technique for 30 consecutive cases in his first year of independent practice during his consultancy without any major intraoperative complications. The author describes this technique in this article with tips and tricks which will especially guide the junior and inexperienced surgeons to avoid running into intraoperative problems while drilling the femoral tunnel.

Salmonellaspp. are carried by and can acutely infect agricultural animals and humans. After ingestion, salmonellae traverse the upper digestive tract and initiate tissue invasion of the distal ileum, a virulence process carried out by the type III secretion system encoded withinSalmonellapathogenicity island 1 (SPI-1). Salmonellae coordinate SPI-1 expression with anatomical location via environmental cues, one of which is bile, a complex digestive fluid that causes potent repression of SPI-1 genes. The individual components of bile responsible for SPI-1 repression have not been previously characterized, nor have the bacterial signaling processes that modulate their effects been determined. Here, we characterize the mechanism by which bile represses SPI-1 expression. Individual bile acids exhibit repressive activity on SPI-1-regulated genes that requires neither passive diffusion nor OmpF-mediated entry. By using genetic methods, the effects of bile and bile acids were shown to require the invasion gene transcriptional activatorhilDand to function independently of known upstream signaling pathways. Protein analysis techniques showed that SPI-1 repression by bile acids is mediated by posttranslational destabilization of HilD. Finally, we found that bile acids function synergistically to achieve the overall repressive activity of bile. These studies demonstrate a common mechanism by which diverse environmental cues (e.g., certain short-chain fatty acids and bile acids) inhibit SPI-1 expression. These data provide information relevant toSalmonellapathogenesis during acute infection in the intestine and during chronic infection of the gallbladder and inform the basis for development of therapeutics to inhibit invasion as a means of repressingSalmonellapathogenicity.

This study evaluated the characteristics and clinical course of patients with iris cysts in the long-term follow-up (24–48 months). We retrospectively analyzed the medical records of 39 patients with iris cysts (27 women and 12 men). Age, visual acuity, intraocular pressure (IOP), slit-lamp evaluation, and ultrasound biomicroscopy images were assessed. The mean age at diagnosis was 40.6 ± 17.48 years. Thirty (76.9%) cysts were peripheral, five (12.8%) were located at the pupillary margin, two (5.1%) were midzonal, and two (5.1%) were multichamber cysts extending from the periphery to the pupillary margin. A total of 23 (59%) cysts were in the lower temporal quadrant, 11 (28.2%) were in the lower nasal quadrant, and 5 (12.8%) were in the upper nasal quadrant. Cyst size was positively correlated with patient age (rs = 0.38, p = 0.003) and negatively correlated with visual acuity (rs = −0.42, p = 0.014). Cyst growth was not observed. The only complication was an increase in IOP in three (7.7%) patients with multiple cysts. The anatomical location of the cysts cannot differentiate them from solid tumors. The vast majority of cysts are asymptomatic, do not increase in size, and do not require treatment during long-term follow-up.

The article discusses the possibilities of computed tomography and magnetic resonance imaging when examining patients in an ENT clinic. The authors' materials cover complex observations of diseases of the nose and paranasal sinuses. The patients were operated on, which made it possible to compare the data of radiation studies with operational findings and cytological material. CT scan in coronal projection allows to clarify the diagnosis, determine the possible causes of recurrent sinusitis and identify the individual structural features of the nasal cavity and PNS that contribute to the development of intraoperative complications. When analyzing CT data, special attention should be paid to identifying and correctly interpreting the intranasal anatomy. It is necessary to indicate in detail the location of the cyst of the maxillary sinus, which allows the surgeon to correctly choose the optimal surgical access.

Introduction: Despite good outcomes of CO2 laser of the larynx, a lack of prospective data related to intraoperative complications in the indexed literature is evident. Materials and Methods: An observational, prospective, nonrandomized study. Results: One hundred and twenty-eight patients met the inclusion criteria. The total rate of intraoperative complications was 14.8% (19/128). The rate of complications according to anatomical location was 7 (38.8%) of 18 for supraglottic tumors and 11 (10.3%) of 107 for glottic tumors, and 1 (33.3%) of 3 for subglottic tumors ( P = .001). We do not found difference in complications according to severity (minor vs major complication). Conclusion: Previous studies reported good oncologic outcomes and low complication rates with CO2 transoral laser microsurgery (TOLMS) compared to traditional open surgery. However, it is important to consider the different intraoperative surgical, major and minor complications related to CO2 TOLMS and discuss this with our patients during the preoperative assessment, especially in those patients who need a supraglottic tumor resection.

Aim of the Study. The aim of this prospective study was to analyse the effect of lateral stromal hydration on the morphology of clear corneal incision architecture using the microscope integrated anterior segment OCT. Methods. The cohort included 65 clear corneal incisions of 49 patients who underwent cataract surgery. Corneal incisions were recorded using a Leica Proveo 8 microscope with an intraoperative OCT EnFocus™ device continuously during the surgery. Corneal incision morphology before and after lateral stromal hydration was analysed. Results. Good adaptation of the corneal incision before hydration was present in 39 cases (60%), in 16 cases (24.6%), the prominence of posterior lip was present, and, in 10 cases (15.4%), the posterior lip tongue was inverted/retracted into the incision. In 38 cases (58.5%), hydration had no effect on the incision architecture; most often, it was primarily a well-adapted corneal incision (46.2%), less often an incision with posterior lip prominence (10.8%), or tongue inversion into the incision (1.6%) prior to hydration. Hydration worsened the incision architecture in 14 cases (21.5%); most often, it induced/worsened posterior lip prominence (15.4%), less often posterior lip retraction (1.6%), tongue inversion into the incision (1.6%), gap development in the peripheral part of the corneal incision (1.6%), or incomplete opening of the corneal incision (1.6%). In 13 cases (20%), hydration improved the incision architecture, especially in cases with inverted or retracted posterior lip tongue (12.3%), less often in cases with posterior lip prominence (7.7%). Conclusion. Lateral stromal hydration seldom affects the condition of the corneal incision. Still, it can cause both deterioration and improvement of the corneal incision architecture. Intraoperative OCT provides real-time monitoring of corneal incision morphology during hydration procedure.

Abstract Background Inguinal pain, unexplained hind limb lameness, back pain or behavioural problems in geldings could be attributable to painful neuromas that develop as a consequence of crushing and severing the testicular nerves during castration. The presence of neuroma in this anatomical location has never been reported, hence the knowledge of possible clinical relevance is limited. The aim of this study was to histologically investigate the testicular nerves at the castration site in geldings for the presence of neuromas. Proximal spermatic cord remnants were collected from 20 geldings admitted to routine post mortem examination for various reasons. The time of castration was unknown, but it had not been performed during the last year. Spermatic cord specimens were immersed in 10% formalin, trimmed, dehydrated, embedded in paraffin, sectioned and stained with haematoxylin and eosin (HE) for light microscopy. Identification of nerve tissue was done by immuno-localization of nerve specific enolase (NSE). Results Neuromas were found in 21 spermatic cords from 13 geldings and were bilateral in eight of the horses. The neuromas consisted of areas with small groups of non-neoplastic proliferations of peripheral neural tissue. The tissue included neurofilaments and Schwann cells, intermingled or surrounded with, epineural, perineural and endoneural fibrous tissue. The neural tissue immunostained positive with NSE. Conclusions This study showed neuromas of the remnant testicular nerves at the site of castration. Further studies are required to establish if these neuromas in the castration site are painful and if certain castration methods promote their formation. Future studies should also investigate the clinical consequence of these neuromas for the individual horse.

Abstract Background The abdomen plays a leading role in the aesthetic image of the human body, and is of prime importance in defining the overall contour of the individual. The abdomen is cited as the location with the most severe deformities after weight loss and the deformities are highly variable. Objectives The aim of this study is to compare between complications of abdominoplasty after weight loss by bariatric surgeries versus weight loss by non surgical methods according to operative time, intraoperative complications: bleeding, postoperative complications: seroma, hematoma, infection, wound-healing problems, and skin flap necrosis and final aesthetic outcome. Patients and Methods This study includes forty patients with abdominal wall redundancy after bariatric surgeries and non surgical methods. All the patients will be examined as regards age, sex, weight, height, BMI, general examination, co-morbidities & associated ventral hernia. This study was conducted in 6 months between April 2017 and October 2017 on patients who were admitted to El Demerdash hospital or authorized medical institutions under supervision of thesis supervisors. Results In this study the mean age of the post bariatric group was 44 years and the non surgical group was 42.4 years. The mean BMI of the post bariatric group was 29.9, a little higher than the non surgical group which was 28. The Pre - loss BMI of the post bariatric group was higher than the non surgical group. The ideal lost weight, actual lost weight and percent of lost weight of the post bariatric group was higher than the non surgical group. The resection weight and the operative time of the post bariatric group were higher than the non surgical group. The amount of drain day1, total amount of drain l& drain removal day of the post bariatric group was higher than the non surgical group. Conclusion To conclude, abdominoplasty after weight loss by bariatric surgeries has higher risk of complications more than abdominoplasty after non surgical methods.

The external workload measured in one anatomical location does not determine the total load supported by the human body. Therefore, the purpose of the present study was to characterize the multi-location external workload through PlayerLoadRT of 13 semi-professional women’s basketball players, as well as to analyze differences among anatomical locations (inter-scapulae line, lumbar region, 2× knee, 2× ankle) and laterality (left vs. right) during five tests that represent the most common movements in basketball—(a) linear locomotion, 30-15 IFT; (b) acceleration and deceleration, 16.25-m RSA (c) curvilinear locomotion, 6.75-m arc (d) jump, Abalakov test (e) small-sided game, 10’ 3 vs. 3 10 × 15-m. Statistical analysis was composed of a repeated-measures t-test and eta partial squared effect size. Regarding laterality, differences were found only in curvilinear locomotion, with a higher workload in the outer leg (p < 0.01; ηp2 = 0.33–0.63). In the vertical profile, differences among anatomical locations were found in all tests (p < 0.01; ηp2 = 0.56–0.98). The nearer location to ground contact showed higher values except between the scapulae and lumbar region during jumps (p = 0.83; ηp2 = 0.00). In conclusion, the multi-location assessment of external workload through a previously validated test battery will make it possible to understand the individual effect of external workload in each anatomical location that depends on the type of locomotion. These results should be considered when designing specific strategies for training and injury prevention.

Stress fractures are a common overuse injury among athletes. Repetitive loading during weight bearing causes a broad range of stress reactions, from increased bone remodeling to painful fractures. The literature indicates that such injuries are usually treated conservatively with rest or immobilization, but a more aggressive, surgical approach to treatment of stress fractures has also been reported. This study was designed to identify the factors that influence the decision to treat an athlete surgically or conservatively. An analysis of 28 articles was performed. A cross-tabulation design was used to compare 4 categories with the treatment chosen. The categories included severity, anatomical location, and type of stress fracture, as well as the athletic motivation of the individual. All 4 factors were found to influence the treatment of choice, although it was remarkable that only athletes who demonstrated high athletic motivation were treated surgically.
