Purpose: To assess preliminarily the efficacy and safety of a relatively new surgical modification of phacovitrectomy in eyes with cataract and visually significant asteroid hyalosis (AH). Materials and methods: Prospective, noncomparative, interventional case series of six eyes of six patients (mean age 75.6 years; 1 woman, 5 men) with cataract and visually significant AH treated with a novel surgical technique—a phacoemulsification with anterior vitrectomy through posterior capsulorhexis and intraocular lens (IOL) implantation. Main outcome measures were: best-corrected visual acuity (BCVA), intraocular pressure (IOP), IOL centration, complications. Mean follow-up was 39.17 ± 4.31 months. Results: The mean BCVA (Snellen) improved from 0.26 ± 0.18 to 0.73 ± 0.33 at the end of the follow-up. IOP was in the normal range, and no problems with IOL fixation were observed at the end of the follow-up. No post-operative complications, retinal detachment, retinal tears, macular edema or prolonged inflammation were observed. Conclusions: The presented new surgical technique seems to be a safe and efficacious method to treat cataract with visually significant asteroid hyalosis.

Purpose. The black iris-lens diaphragm (ILD) can be used in the treatment of traumatic aniridia and aphakia. The aim of our study was to show postoperative functional and anatomic results and complications in a small case series. Methods. We retrospectively analyzed the files of 16 patients managed with a black ILD or a sole iris diaphragm in the period 1994–2007. Four of them were female and 12 were male. The mean age of the group was 50±17 years. At the time of the implantation, all of the eyes had already undergone primary surgical repair. Results. The preoperative best-corrected visual acuity in half of the patients was ≥0.1 and remained stable after the first postoperative year. During the follow-up years, one eye developed a subluxation of the implant and one eye an anterior chamber hemorrhage. At the same time, out of 8 eyes carrying a silicone tamponade in the vitreous cavity, silicone oil entered the anterior chamber in 3 cases. In one case, enucleation was undertaken due to phthisis. Conclusions. In the case of severely traumatized eyes with aniridia and aphakia, the implantation of a black ILD can have a positive effect on functional and anatomic stabilization.

Abstract PurposeTo study visual outcomes after implantation of Versario intraocular lenses (IOLs) Patients and MethodsIn 20 selected patients (40 eyes) uneventful, bilateral cataract surgeries with implantation of trifocal Versario (IOLs) were performed. Designprospective case series. Six months after surgery the following parameters were analysed: binocular uncorrected visual acuities (log MAR): for distance (UDVA) at 4 m, for intermediate (UIVA) at 60, 70, 80 cm and for near (UNVA) at 40 cm, photopic defocus curve, mesopic and photopic contrast sensitivities (CSs), spectacle independence, visual function test questionnaire (modified VFQ-25), subjective symptoms and postoperative complications. ResultsSix months after surgery, the mean of binocular visual acuities were as follows: UDVA: -0.12 ± 0.08; UIVA (60 cm): +0.07 ± 0.10, (70 cm): +0.05 ± 0.11, (80cm): +0.07 ± 0.09; UNVA (40cm): +0.12 ± 0.08. CSs in mesopic and scotopic conditions for distance and photopic for near were between normal range of age- match healthy control. All patients were spectacle independent. General satisfaction was high and equal 9.37±0.83. No severe glare and halo were detected. There were no postoperative complications. ConclusionsThe bimanual MICS with the Versario lenses implantation was a safe and effective method for patients who want to be spectacle independent at different distances.

CONTEXT AND OBJECTIVE: Most bariatric surgical techniques include essentially non-physiological features like narrowing anastomoses or bands, or digestive segment exclusion, especially the duodenum. This potentially causes symptoms or complications. The aim here was to report on the preliminary results from a new surgical technique for treating morbid obesity that takes a physiological and evolutionary approach. DESIGN AND SETTING: Case series description, in Hospital Israelita Albert Einstein and Hospital da Polícia Militar, São Paulo, and Hospital Vicentino, Ponta Grossa, Paraná. METHODS: The technique included vertical (sleeve) gastrectomy, omentectomy and enterectomy that retained three meters of small bowel (initial jejunum and most of the ileum), i.e. the lower limit for normal adults. The operations on 100 patients are described. RESULTS: The mean follow-up was nine months (range: one to 29 months). The mean reductions in body mass index were 4.3, 6.1, 8.1, 10.1 and 10.7 kg/m², respectively at 1, 2, 4, 6 and 12 months. All patients reported early satiety. There was major improvement in comorbidities, especially diabetes. Operative complications occurred in 7% of patients, all of them resolved without sequelae. There was no mortality. CONCLUSIONS: This procedure creates a proportionally reduced gastrointestinal tract, leaving its basic functions unharmed and producing adaptation of the gastric chamber size to hypercaloric diet. It removes the sources of ghrelin, plasminogen activator inhibitor-1 (PAI-1) and resistin production and leads more nutrients to the distal bowel, with desirable metabolic consequences. Patients do not need nutritional support or drug medication. The procedure is straightforward and safe.

Purpose: To describe a new surgical technique for managing Ahmed Glaucoma Valve tube exposure. The technique is simple, safe, easy to perform and may be an interesting alternative to conventional covering of the tube. This technique allows unlike the classical ones to act on the cause and not only on the complication of extrusion. Materials and Methods: This study was a retrospective case series that included four eyes of four patients who presented with an Ahmed Glaucoma Valve tube exposure. Results: Surgery was uneventful in all cases and we did not observe any intraoperative or postoperative complications. After at least 1-year follow-up, no case of tube re-exposure was detected. Conclusions: Many techniques have been proposed in order to cover the extruded tubes, and different materials may be used to reinforce the coverage, but re-exposure of the tube is a possible scenario. Indeed, our technique attempts not only to cover the exposed tube but also to solve the cause of the extrusion.

BACKGROUND: Atomoxetine uses a novel nonstimulant approach to the treatment of attention deficit hyperactivity disorder. There is limited information on overdose of atomoxetine in children or adults. OBJECTIVE: To provide information on atomoxetine in overdose. METHODS: Case series were conducted at 3 regional poison centers for atomoxetine ingestion in children (age ⩽17 y). Exclusion criteria were polypharmacy or lack of follow-up. RESULTS: Forty patients were included (25 boys; 63%) in the study. The mean ± SD age was 6.1 ± 4.9 years (range 9 mo–17 y). Twenty-five patients were managed at home, 14 in hospital emergency departments (3 children were admitted), and 1 patient was managed in a physician's office. Symptoms reported were tachycardia, drowsiness, nausea, hypertension, and vomiting. A seizure was reported in one child who had recently started atomoxetine therapy. No arrhythmias beyond sinus tachycardia were reported. Mean maximum heart rate in patients with tachycardia was 131 ± 14 beats/min. The mean dose ingested, categorized by medical outcome, was: no effect (n = 22), 40 ± 32 mg; minor effect (n = 14), 167 ± 221 mg; and moderate effect (n = 4), 249 ± 326 mg. There were no major outcomes or fatalities. The lowest dose ingested that resulted in hypertension was 480 mg, in a 14-year-old girl (BP 136/95 mm Hg). CONCLUSIONS: In this case series, clinically significant cardiovascular effects requiring direct intervention did not occur. Activated charcoal and/or observation appear to be sufficient for accidental ingestion. Further investigation may be needed to indicate whether seizures occur from atomoxetine ingestion.

Introduction: This prospective case series study aimed to assess the value of the Less Invasive Stabilization System (LISS) to treat closed Segmental Tibial Fractures (STFs) using a proposed surgical technique.Materials and methods: Between August 2010 and January 2014, 21 consecutive recently (within 1 week) closed STFs that matched the inclusion criteria were enrolled. Patients were treated with the 13-hole LISS plate. All patients were followed up every 2 weeks for the first 2 months, then every month for the rest of the first 6 months and then every 6 months thereafter. Patients were assessed radiologically during the follow-up appointments and clinically at the final visit by the Lower Extremity Functional Scale (LEFS) to evaluate the result.Results: The mean time to union of the proximal fracture was 15.72 ± 2.78 (range: 12–20) weeks and for the distal fracture was 20 ± 2.22 (range: 16–24) weeks, excluding delayed union in three patients. All patients except the three showed radiological observable callus in a mean duration of 4.95 (range: 3–7) weeks. The mean final follow-up LEFS was 72.4 (range: 60–80).Conclusion: The mean time to union of the proximal fracture was shorter than the distal fracture. The use of LISS to treat closed STFs using the proposed surgical technique has proved to give favorable results. Further studies using the described technique are needed to justify the achieved results.Level of evidence: IV (Prospective case series).

Objectives: The objective was to evaluate the clinical results of a new surgical technique to improve the Bankart repair by adding a prosthetic block called the Recenter. Methods: Thirty-two patients were retrospectively included in this multicenter study. Five patients were lost to follow-up. The surgical indications were similar to those for a standard Bankart repair. A metal implant called a Recenter was inserted in the anterior inferior glenoid and fixed with two TightRopes. A Bankart repair was then performed over the implant. All the patients had a follow-up CT scan and a clinical examination. The mean follow-up period was 37 months (29-47). The mean ISIS score was 2.42 (0-6). Results: Twenty-six patients aged 33.9 ± 10.2 (16-50) years were included. Patients presented with an average of 2.4 ± 3.2 (0-12) true dislocations prior to surgery and 6.1 ± 8.5 (0-30) subluxations. The time that had elapsed between the occurrence of the first symptoms and surgery was 6.8 ± 6.9 years. The last follow-up showed a residual VAS score of 1.3. The mean Walch-Duplay score was 78.9 ± 21.4 - SD (range 5-100), the mean ROWE score, 88.5 ± 15.9 - SD (30-100) and the mean SST score, 90.6 ± 14.5 - SD (41.6-100). 77.8% of the patients (n=21) had no apprehension, 11.1% (n=3) were apprehensive, 7.4% (n=2) were afraid of the possibility of luxation and 3.7% (n=1) had a recurrence. In terms of satisfaction, 59.3% were very satisfied, 33.3% satisfied and 7.4% dissatisfied with their operation. Concerning the CT study, we found no shifting of material or ballooning of the TightRope tunnels. Conclusion: The Recenter showed a recurrence rate of 4% (1 patient) with an average follow-up of 3 years. Despite a small number of patients, the Recenter appears to be a worthwhile addition to the arthroscopic Bankart technique.

Abstract Background and purpose: The medial closing-wedge distal femoral varus osteotomy (MCW-DFVO) was an excellent operation for painful valgus lateral unicompartmental osteoarthritic (OA) knee, especially in the young patient. Originally, it requires a medial approach that has more precarious. On top of that, releasing of the iliotibial band (ITB) that is the deforming force needs added incision. Therefore, this study aims to describe the new surgical technique of MCW-DFVO that uses a lateral approach and lateral plating to treat the valgus OA knee. Additionally, we also reveal the outcomes of our technique as the case series.Materials and method: Ten patients (12 knees) who underwent MCW-DFVO via a lateral approach were retrospectively reviewed. The inclusion criteria were age > 18 years, isolated lateral compartmental OA knee, no significant patellofemoral pain, and ROM > 90 degrees. We excluded the inflammatory joint disease, unstable knee (femorotibial joint subluxation > 1 cm), and prior surgical procedure. Demographic data, pre- and postoperative ROM, radiographic outcomes, complications, and survivorship were recorded.Results: The mean age, body mass index, and preoperative ROM were 55.3 ± 4.0 years, 25.4 ± 3.7 kg/m2and 113.3 ± 11.5 degrees, respectively. The preoperative valgus deformity was 162.3 ± 4.8 degrees, and the Final post-operative alignment was 182.3 ± 2.6 degrees. Overall mean operative time of this technique was 92.5 ± 26.7 minutes. During the follow-up period, post-operative ROM was decreased to 108.8 ± 11.7 degrees. One knee required plate removal due to hardware irritation, and another knee required subsequent total knee arthroplasty (TKA) at 1 and 8.5 years after DFVO, respectively. The survivorship of this technique was 91.7% at the mean survival time of 13.8 years (95% confidence interval, 11.9 – 15.7 years).Conclusion: This study proposed the new surgical technique of MCW-DFVO via a lateral approach. This technique provided a satisfactory outcome and excellent survivorship. However, further research with a larger sample size was required.

SummaryTwenty-one cardiothoracic surgical patients have been treated with fibrin as a topical hemostatic/sealing agent, prepared from bovine fibrinogen clotted with bovine thrombin. Serum samples have been collected before treatment with fibrin and postoperatively between 1 and 9 days, 3 and 12 weeks, and 6 and 8 months. The titers of anti-bovine fibrinogen antibodies, measured by ELISA specific for immunoglobulins IgG or IgM, increased to maximal values after about 8 or 6 weeks, respectively. After 8 months, IgG titers were on average 20-fold lower than the mean maximal value, while IgM titers returned to the normal range. IgG was the predominant anti-bovine fibrinogen immunoglobulin as documented by ELISA, affinity chromatography and electrophoresis. Anti-bovine fibrinogen antibodies present in patients reacted readily with bovine fibrinogen, but did not cross-react with human fibrinogen as measured by ELISA or by immunoelectrophoresis. A significant amount of antibodies against bovine thrombin and factor V has been found, many cross-reacting with the human counterparts. No hemorrhagic or thrombotic complications, or clinically significant allergic reactions, occurred in any patient, in spite of antibody presence against some bovine and human coagulation factors. The treatment of patients with bovine fibrin, without induction of immunologic response against human fibrinogen, appeared to be an effective topical hemostatic/sealing measure.
