Retrospective analysis of silicon intubation by Ritleng probe and Sutupak suture fixed in silicone tube in congenital nasolacrimal duct obstruction.

Purpose:The aim of this study was to perform a retrospective review of the outcome of silicon intubation using the Ritleng probe and a modified braided silk suture (Ethicon Sutupak) fixed in a silicone tube in children with congenital nasolacrimal duct obstruction (CNLDO).Methods:Records of all children between 1 and 12 years of age who underwent silicone tube intubation with the Ritleng probe and Ethicon Sutupak suture (2-0) fixed in silicone tube for CNLDO with a minimum of 1-year follow-up were identified. The hollow Ritleng probe was inserted via the canaliculus into the inferior meatus. The Sutupak thread-guide, attached to the silicone tube, was advanced through the probe lumen and retrieved using a hook under endoscopic visualization. The tube ends were tied to each other and tube removal was planned after 3 months. Absence of watering, discharge, and matted lashes after removal of silicone tube was defined as success.Results:One hundred and fifty-two eyes of 152 children with a mean age of 3.26 ± 2.3 years were included in the study. The procedure was successful in 145 eyes (95%) after removal of the silicone intubation with relief of symptoms observed in most patients by fifth-day follow-up (n = 120 eyes, 83%). The mean duration of follow-up was 3.48 ± 1.3 years. No other significant differences were observed between patients who did (n = 47) and did not (n = 105) have previous probing including success rates (95% vs. 96%, P = 0.89).Conclusion:Silicone intubation with Ritleng probe and Sutupak suture fixed in silicone tube was successful in resolution of symptoms of CNLDO in majority of patients. Using a low-cost suture did not affect success rates.

Evaluation of the anatomical factors affecting the success of retrograde intrarenal surgery for isolated lower pole kidney stones.

Studies which examine the factors affecting success rate in kidney stones located in the lower pole as well as the effects of infundibulopelvic angle (IPA) and infundibular length (IL) have been conducted with a small number of patients. We aimed to evaluate the cut-off points of IPA and IL parameters that effect the success of retrograde intrarenal surgery (RIRS) for isolated lower pole kidney stones. This retrospective study includes 168 patients who underwent primary RIRS due to isolated lower pole kidney stones in our clinic between January 2013 and May 2020. Pre-operative demographic data, medical history, physical examination, surgery duration as well as the post-operative hospitalization time of patients specifics were obtained. According to pre-operative computed tomography (CT), stone size, stone burden, stone density, number of stones (single and multiple), stone laterality, congenital kidney abnormality, the presence of solitary kidney, parameters of IPA and IL were measured and both included in the study. All patients were divided into two groups as the successful group and the unsuccessful group according to their post-operative success. These two groups were compared in terms of pre and post-operative data. Stone burden, IPA < 42.65°, and IL > 27.5mm were specified as the independent risk factors for success of RIRS procedure. The patients for whom RIRS procedure is planned for lower pole kidney stones, stone burden, IPA, and IL should be taken into consideration to be able to predict success and it should be kept in mind that additional treatment may be required.

Endoscopic third ventriculostomy and cerebrospinal fluid shunting for pure communicating hydrocephalus in children.

Recent reports regarding endoscopic third ventriculostomy (ETV) for pediatric hydrocephalus revealed that ETV could avoid cerebrospinal fluid (CSF) shunting in certain types of hydrocephalus. However, the effectiveness of ETV for "pure" communicating hydrocephalus that has no obstruction through CSF pathway is still unknown. In this study, we report clinical outcome of ETV and CSF shunting for communicating hydrocephalus and discuss the efficacy of ETV for pure communicating hydrocephalus. Children less than 15years old who underwent ETV or CSF shunting for communicating hydrocephalus were retrospectively reviewed. The absence of obstruction through CSF circulation was confirmed by CT cisternography or cine-contrast image in MRI. Sixty-three patients (45 CSF shunting and 18 ETV) were included. The mean follow-up period was 6.1years. The success rate was 60% in CSF shunting and 67% in ETV at the last visit (p = 0.867). Normal development was observed in 24 patients (53%) in CSF shunting and 12 patients (67%) in ETV (p = 0.334). There was a significant difference in the mean time to failure (CSF shunting: 51.1months, ETV 3.6months, p = 0.004). The factor that affected success rate in ETV was the age at surgery (success 21.6months, failure 4.4months, p = 0.024) and ETV success score (success 66.7, failure 50.0, p = 0.047). Clinical outcomes of ETV were not inferior to those of CSF shunting in patients with communicating hydrocephalus. Further studies is required to elucidate to establish the consensus of ETV as a treatment option for communicating hydrocephalus.

The effects of different environments on older adults' ability to successfully cross a closing gap in virtual reality.

To navigate through dynamically changing environments and to avoid collisions with stationary and moving obstacles, older adults tend to over rely on their visual system because it is a more reliable source of information. Aging affects both visuomotor integration and visual perception, often resulting in the inability to produce appropriate adaptive locomotor actions in a timely manner. Does peripheral visual information in the environment affected older adults' ability to complete a gap-crossing task with a set of closing doors at different rates (0.6-1.2 m/s)? Fifteen older adults (65-74 years) completed the study inside a virtual environment with three different levels of peripheral visual information: 1) empty; 2) stationary avatars; and 3) moving avatars. Kinematic data was collected using an Optotrak camera system to track the older adults' body movements during the task. The results demonstrated that regardless of the environment or closing door speed, older adults maintained consistent approach speeds. However, older adults collided with the fastest moving doors a significant number of times at the fastest door closing rates for the empty and moving avatar conditions. Although it appears that older adults are able to attend on a central task (i.e., passing through closing doors) and maintain constant behaviours regardless of the visual information from peripheral environment, richness of the peripheral environment provides accurate feedback about self-motion affects success rates.

The Role of Hydraulic Silicate Cements on Long-Term Properties and Biocompatibility of Partial Pulpotomy in Permanent Teeth.

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

A study of factors affecting the success rate of type-1 tympanoplasty

&lt;p class="abstract"&gt;&lt;strong&gt;Background: &lt;/strong&gt;Chronic otitis media (COM) (tubo-tympanic) is a common ear pathology for which tympanoplasty is done. Factors that affect the success rate of tympanoplasty can be patient related (age, gender, socio-economic status), disease related (duration and severity of symptoms) or technique related (equipment and surgical approaches). This study was undertaken to know the factors affecting success rate of type-1 tympanoplasty at our institute.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; This was a prospective observational study conducted at ENT Department of Gujarat Adani Institute of Medical Sciences, Bhuj, from October 2017 to July 2019. All patients between 20 and 60 years of age with inactive mucosal COM operated for type-1 tympanoplasty were included in the study. Pre-operative, intra-operative and post-operative details were recorded as per the pre validated proforma and evaluated using Chi-square and paired t-test.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results: &lt;/strong&gt;100 patients were included in our study. Females were more commonly affected (61%) than males (39%). In 78% of patients one ear was affected (left 40%, right 38%). Ear discharge was the most common symptom (99%). Maximum patients (55%) had a moderate perforation. The perforation was central in all cases. Microscopic surgery was done in 79% of patients. Post aural approach (Wilde’s incision) was the most common approach used (70%). The most common graft material used was temporalis fascia (96%). In 61% of patients graft was kept by underlay technique.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;In our study, the success rate of tympanoplasty was significantly more when duration of discharge was less, microscope was used for surgery and post aural approach was used. Success rate was less when there was history of any previous nasal pathology. Other factors, like age, gender, socio-economic class, occupation, side of involvement of ear, size and site of perforation and grafting techniques, did not affect the success rate of tympanoplasty.&lt;/p&gt;

Luaran Transfer Embrio Simpan Beku pada Pasien Endometriosis Pasca Operasi dan Non Endometriosis yang Menjalani IVF di Klinik Permata Hati RSUP Dr. Sardjito

Background: Endometriosis is a chronic condition that is influenced by the hormone estrogen which affects women of childbearing age, and is associated with pelvic pain and infertility. In Vitro Fertilization (IVF) is currently the most efficient assisted reproductive technology and its high success rate is often done for infertility therapy in women associated with endometriosisObjective: The aim of this study is to determine whether postoperative endometriosis affected pregnancy outcomes in patients underwent frozen embryo transfer in IVF / ICSI programs.Method: This Research is done with a retrospective cohort design. The data was taken from medical records, research subjects who met the inclusion and exclusion criteria. The research data was collected, processed and analyzed using SPSS 23. Univariate, bivariate and multivariate data analysis was carried out to determine the effect between variablesResult: There were 458 research subjects in this study. Endometriosis patients were 119 subjects (26%). 57 subjects were categorized as minimum-mild endometriosis (47.9%) and moderate-severe subjects as many as 62 subjects (52.1%). The biochemical pregnancy rate (36.31%) and clinical pregnancy (29.4%) in patients with endometriosis was slightly higher than in non-endometriosis. But statistically it did not affect success rate of achieving biochemical (p = 0.428; RR 0.89; 95% CI: 0.71-1.24) and clinical pregnancy (p = 0.535; RR 0.883; 95% CI: 0.63- 1.22). The rate of miscarriage in postoperative endometriosis patients was higher than non-endometriosis patients (88.6% vs 80.7%) but was not statistically significant (p = 0.294; RR 1.69; 95% CI: 0.61-4.67) . Biochemical and clinical pregnancies were significantly affected by age, infertility, endometrial thickness, embryo age and embryo quality. The incidence of miscarriage was affected by the ovarian stimulation protocol.Conclusion: Endometriosis post operative statistically has no effect on pregnancy outcomes in the IVF / ICSI cycle with frozen embryo transfer compared with another cause of infertility .Keywords:Endometriosis, In Vitro Fertilization, Clinical pregnancy, biochemical pregnancy, miscarriage

Successful vaginal birth after cesarean in the second delivery is not associated with the stage of labor of the primary unplanned cesarean delivery

BackgroundCandidates for trial of labor after cesarean must be carefully screened to maximize success and minimize morbidity. Demographic and obstetric characteristics affecting success rates must be delineated. ObjectiveWe examined whether the labor stage of the primary delivery in which a woman underwent an unplanned cesarean delivery would affect the likelihood that she could achieve a subsequent vaginal birth. Study designElectronic medical records-based study of 676 parturients. Trial of labor rates and outcomes were compared between women whose primary cesarean delivery was performed in the first vs. the second stage of labor. SettingHadassah Medical Center, Israel PopulationWomen in their second pregnancies, with singleton fetuses, who underwent unplanned cesarean delivery in their first pregnancy and elected trial of labor in the second delivery. The main outcome measures were maternal and neonatal complications and vaginal birth rates in first vs. second stage of labor groups. ResultsIn our population, 76 % of women attempt trial of labor after cesarean. Rates of successful vaginal delivery did not differ significantly between those who underwent primary cesarean in the first vs. second stage of labor: 67.4 % vs. 70.2 %, p = 0.483, respectively. Among women whose primary UCD was in the second stage, only 18.2 % (35/192) required a UCD in the second stage in the subsequent delivery, while 58.9 % (113/192) underwent UCD in the first stage in both deliveries. ConclusionLabor stage of the primary unplanned cesarean delivery, should not dissuade women from a trial of labor after cesarean in their second delivery.

403 Are You Comfy? Comparing Success Rates of Lumbar Puncture Positions

A lumbar puncture (LP) is commonly performed in the pediatric emergency department for diagnostic purposes; unsuccessful or traumatic LPs can complicate decision making. The sitting position has a larger interspinous space compared to lateral recumbent and is safer in sick neonates at risk for cardiac and respiratory instability. However, few studies have compared the effect of position on LP success and complication rates. The objective of our study was to determine if position affects success rates when performed in infants <3 months old. This is a retrospective chart review in infants aged <3 months who had a LP performed in a pediatric emergency department over a 35-month period. The primary outcome was the rate of successful LPs, defined as obtaining adequate CSF to send for studies. The secondary outcome was the rate of traumatic LPs, defined as >500 RBCs. Summary statistics were calculated and associations were examined using the Wilcoxon rank-sum and Fisher’s exact tests. A total of 557 charts were reviewed, with 116 in the sitting position and 441 in the lateral recumbent position. The primary outcome of adequate CSF fluid collection was not significantly different between groups (63% sitting position versus 58% lateral recumbent position; p = 0.22). In addition, the rate of traumatic LPs showed no significant difference (28% sitting position versus 27% lateral recumbent position; p = 0.84). In secondary analysis (Figure 1), there was a decreased number of LPs with no CSF in the sitting position (0.9%) versus the lateral recumbent position (3.9%), though not statistically significant (p = 0.10). Positioning during a LP in infants <3 months likely does not affect success rates or rates of traumatic LP.

Prospective clinical evaluation of 765 partial glass-ceramic posterior restorations luted using photo-polymerized resin composite in conjunction with immediate dentin sealing

ObjectivesTo evaluate the clinical performance of partial glass-ceramic (IPS e.max Press) posterior restorations.Materials and methodsA total of 765 restorations in 158 patients were placed between 2008 and 2018 and evaluated in a prospective study during regular dental care visits between 2015 and 2018. The restorations were luted with a conventional photo-polymerized resin composite (HFO) in conjunction with an Immediate Dentin Sealing procedure (IDS). Intra-oral photographs and radiographs were made and evaluated using USPHS criteria.ResultsThe mean observation time was 53.3 months (range 3–113 months). Three absolute failures occurred (tooth fractures, n = 2; apical re-infection, n = 1) all leading to the loss of the restored tooth. Repairable and salvageable failures occurred in 9 teeth (endodontic complications, n = 7; secondary caries, n = 1; debonding, n = 1). The survival and success rates according to Kaplan-Meier after 5 years cumulated to 99.6% and 98.6%, respectively. Location (premolar/molar and mandibula/maxilla), pre-restorative endodontic status (vital/devitalised) and extension of the indirect ceramic restoration (number of sides and cusps involved) did not significantly affect the cumulative success rate (log rank test, p > 0.05). The condition of the vast majority of the restorations remained unaffected for 5 years.ConclusionsPartial glass-ceramic posterior restorations (pressed lithium disilicate (IPS e.max press, Ivoclar Vivadent) luted by means of a conventional photo-polymerized resin composite in conjunction with the use of an IDS procedure have an excellent medium-term prognosis.Clinical relevancePartial glass-ceramic posterior restorations can be considered as a highly reliable treatment option. Location and extension of the restoration and pre-restorative endodontic status do not affect success rate.

Does intraoperative penile tourniquet application during hypospadias repair affect the patients and surgeons reported outcomes? A randomized controlled trial

Hemostasis aimed to maintain the bloodless surgical field for better exposure for the surgeon. There are no trials regarding the impact of hemostasis techniques for hypospadias surgery on surgeon satisfaction and patients' reported outcomes. Application of penile tourniquet is a common practice in hypospadias surgery that aims at reducing blood loss and improving visualization. Yet, scarce data exist on the effect of penile tourniquet on hypospadias repair outcomes. To evaluate the safety and efficacy of restraining penile perfusion using a tourniquet in hypospadias repair on the surgical outcome, also surgeons and patients reported outcomes. To evaluate the effect of penile tourniquet application on hypospadias repair outcome and surgeon's satisfaction with intraoperative hemostasis. In this single-blinded randomized controlled trial, a total of 110 children with distal hypospadias amenable for TIP repair were assigned to hypospadias repair with or without intraoperative application of a penile tourniquet. Surgeries were performed by a junior (2-5 years of experience in TIP repair) or a senior pediatric urologist (with >5 years of experience). Intraoperative blood loss, the number of times bipolar diathermy was used, hemoglobin deficit, and operative time were compared. Surgeon's satisfaction with intraoperative hemostasis was evaluated using a 4-tiered questionnaire. Patients were followed up for a minimum of one year. Complications and readmission rates were compared. The patient-reported outcome of hypospadias repair was assessed using the hypospadias objective scoring evaluation (HOSE). Baseline patient demographics and hypospadias characteristics were comparable between the study groups. Bipolar diathermy was more often used in the non-tourniquet group (mean±SD=5.7±1.8 times vs. 6.7±1.9 for the tourniquet group; p=0.007). Also, the operative time was longer in non-tourniquet group [mean=54.7±14.9 vs. 60.8±12.5min (p=0.028)]. Junior surgeons were more likely to be satisfied with hemostasis when a tourniquet was used (97.4% vs. 79.5%, p=0.02). Postoperative complications, readmission rates, and patient-reported outcomes were similar between both groups. The application of penile tourniquet during hypospadias repair can reduce operative time and the need for diathermy use; and also improves junior surgeon's satisfaction with intraoperative hemostasis without adversely affecting success rates or patient-reported outcomes.

Preimplantation Genetic Screening and The Success Rate of In Vitro Fertilization: A Three-Years Study on Iranian Population.

In vitro fertilization (IVF) is one of the most efficient approaches within the context of assisted reproductive technology (ART) to treat infertility. High pregnancy rates have become the major index of successful IVF in clinical studies. It is not clear yet which factors are certainly responsible for IVF success, as various outcomes were obtained in different IVF centers with different settings. In this study, we aimed to address controversies in the interpretation of promising results of IVF with respect to preimplantation genetic screening (PGS). In this retrospective case series study, we built a dataset containing data from 213 IVF patient candidates for PGS (654 embryos) with blastomere biopsy at day 3 and trophectoderm biopsy in day 5, referred to Royan Institute, Tehran, Iran from 2015 to 2018. Next, the data were analyzed to find influential factors affecting success rate of ART cycles. Data analyses showed that regardless of PGS indications (ART failures, recurrent miscarriage, chromosomal abnormalities, etc.), the pregnancy rate is influenced by maternal and embryonic factors such as the age of mother as well as quantity and quality of transferred embryos. Furthermore, genotyping of embryos using array comparative genomic hybridization (aCGH) depicted the highest rate of chromosomal aberrations for chromosomes 1, 16 and 19 while the lowest frequency for chromosomes 11 and 17. Similarly, we detected 463 genetically abnormal embryos by aCGH, among which only 41.9% could be detected by classical fluorescent in situ hybridization (FISH) method. This study not only highlighted the advantages of aCGH over the FISH method in detection of chromosomal abnormalities, but also emphasized the importance of genetic abnormality as an indication for determination of IVF success rate.

Clinical, hemodynamic, and functional variables affecting success rate of coronary flow velocity reserve detection during vasodilator stress echocardiography.

Stress echocardiography (SE) with state-of-the-art imaging protocol allows a comprehensive assessment of regional wall-motion abnormalities and Doppler-based coronary flow velocity reserve (CFVR) in left anterior descending artery (LAD). We sought to assess the variables potentially impacting on success rate of SE with CFVR. In a single-center, prospective, observational study design, from 2007 to 2019, we enrolled 2989 consecutive patients (age 67±12years; 1723 men) referred for SE, without contrast, for chronic known (n=1130) or suspected (n=1859) coronary syndromes. Coronary flow velocity reserve was measured as stress/rest peak diastolic flow velocity. The same operator (LC) performed all examinations with the same machine (GE Vivid 7). Interpretable CFVR was obtained in 2808 patients (feasibility=93.9%). Overall success rate was lowest (91.4%) in 2007-2008 and steadily rose to 97.8% in 2017-2019 (P for trend <.0001). Feasibility was excellent for men (93.7%) and women (94.3%) (P=.47) across all values of body mass index (BMI): <25 (P=.09), 25-29 (P=.84), and ≥30 (P=.23). At multivariable logistic regression analysis, women with BMI≥30 (OR 1.94, 95% CI 1.14-3.29, P=.02), resting heart rate ≥77beats/min (OR 2.25, 95% CI 1.64-3.11; P<.0001), and stress-induced ischemia in the LAD territory (OR 3.14, 95% CI 1.67-5.90; P<.0001) predicted unfeasible CFVR. Vasodilator SE with CFVR combined with wall-motion analysis is highly feasible also without contrast although with a slight decline in presence of high resting heart rate (reducing diastolic time essential for flow imaging), women with BMI≥30 (increasing tissue thickness interposed between transducer and artery), and anterior ischemia (for underlying low-absent anterograde flow for severely stenotic or occluded LAD).

Cut and paste: temperature-enhanced cotyledon micrografting for Arabidopsis thaliana seedlings

BackgroundCotyledon micrografting represents a useful tool for studying the central role of cotyledons during early plant development, especially their interplay with other plant organs with regard to long distance transport. While hypocotyl micrografting methods are well-established, cotyledon micrografting is still inefficient. By optimizing cotyledon micrografting, we aim for higher success rates and increased throughput in the model species Arabidopsis thaliana.ResultsWe established a cut and paste cotyledon surgery procedure on a flat and solid but moist surface which improved handling of small seedlings. By applying a specific cutting and joining pattern, throughput was increased up to 40 seedlings per hour. The combination of short-day photoperiods and low light intensities for germination and long days plus high light intensities, elevated temperature and vertical plate positioning after grafting significantly increased ‘ligation’ efficiency. In particular high temperatures affected success rates favorably. Altogether, we achieved up to 92% grafting success in A. thaliana. Reconnection of vasculature was demonstrated by transport of a vasculature-specific dye across the grafting site. Phloem and xylem reconnection were completed 3–4 and 4–6 days after grafting, respectively, in a temperature-dependent manner. We observed that plants with grafted cotyledons match plants with intact cotyledons in biomass production and rosette development.ConclusionsThis cut and paste cotyledon-to-petiole micrografting protocol simplifies the handling of plant seedlings in surgery, increases the number of grafted plants per hour and greatly improves success rates for A. thaliana seedlings. The developed cotyledon micrografting method is also suitable for other plant species of comparable size.

Prognostic factors affecting success rate in endoscopic management of spontaneous cerebrospinal fluid rhinorrhea

Objective Endoscopic sinus surgery has been established as the standard procedure for management of most cases of cerebrospinal fluid (CSF) rhinorrhea and meningoceles. Spontaneous leak represents the most common etiology, whether it is associated with idiopathic intracranial hypertension or not. Nevertheless, results of endoscopic repair of spontaneous CSF leaks represent the worst among other nonspontaneous etiologies in most literatures, with a wide range of success (25–87%). Patients and methods This is a retrospective study that included 52 cases of spontaneous CSF leak, which had been managed by endoscopic sinus surgery, in the last 8 years, in Kasr Alaini Hospital, Faculty of Medicine, Cairo University, and Shebin Alkom Teaching Hospital; and also some cases were done in New Kasr Alaini Teaching Hospital. Data collected included age, sex, manifestations of high intra cranial tension (ICT), duration of leak, site, method of repair, and whether repair was successful or not. Results In 52 cases with spontaneous CSF leak, successful repair was achieved in 73% (38 out of 52). There were 41 (78.8%) female and 11 (21.2%) male patients. Success in female patients was 70.7% (29 of 41 cases), and success in male patients was 81.8% (9 of 11 cases). Manifestations of increased ICT were found in 17 of 52 cases (32%), where nine of them failed (52%). Leaks in the ethmoidal region represented 27 (52%) cases, sphenoidal region 19 (36.5%) cases, and frontal region six (11.5%) cases. There were three methods of repair: in the first group, repair was done with fat and overlay mucosal graft in 17 (33%) cases; in the second group, repair was done with under lay epidural graft plus overlay mucosal graft in 29 (56%) cases; and in the third group, an underlay graft was used, and in addition, an overlay septal flap was put in six (11%) cases. Conclusion Spontaneous CSF leak represents a common cause of CSF rhinorrhea. Success rate is in general lower than in other etiologies of CSF leaks. The outcome of the surgical intervention could be related to variable demographic and preoperative factors.

From the total 1872 we choose 75 patients were they don't need sinus lifting. Cases divided into 2 groups were group A are the cases were dental implant performed without sinus augmentation or lift (No SA.), group B are the cases were dental implant performed with sinus augmentation lift (DSA.).&#x0D; Results: Perforation was the most serious complications which need to be avoided in DSL cases. Its need special skill, gentle alert works. Accurate management of the complications can give good result without affecting success rate.&#x0D; Conclusion: Careful analysis via imaging, precise surgical techniques and an understanding of the anatomy of the surgical area are essential in preventing complications. One should be aware of the possible complications related to implant placement so that the patient can be properly informed.

Erbium:YAG laser treatment of female stress urinary incontinence: midterm data.

Stress urinary incontinence (SUI) is treated using intravaginal laser therapy. We wanted to find out how incontinence severity at baseline and the number of laser interventions affect success rate, and whether the effect of laser therapy was obvious 6months and 2years after the last laser intervention. Fifty-nine women, 32 with SUI I, 16 with SUI II, and 11 with SUI III were treated using an erbium-doped yttrium aluminium garnet (Er:YAG) laser following the IncontiLase® protocol. Therapy included five laser sessions with a 1-month interval between sessions. Objective (1-h pad test) and subjective data (International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI SF], Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire [PISQ-12]) were assessed at baseline, after two and four laser sessions and 6months and 2years after the fifth laser session. Objective cure/improve rates for mild SUI I were 69%, 78%, 91%, and 78% after two, four, and five laser sessions at the 6-month and 2-year follow-ups. Subjective cure rates (ICIQ-UI SF) were 53%, 69%, 72%, and 66%, and sexual function (PISQ-12) also improved. For SUI II, objective cure/improve rates were 31%, 63%, 69%, and 50%. Subjective cure rate was 13% at the 2-year follow-up. For SUI III, only one patient had an objective improvement after two and four laser sessions. Intravaginal laser therapy led to cure/improvement for SUI I and SUI II, but not for severe SUI III. Outcome was better after four to five laser sessions than after two laser sessions. Follow-up data6months and 2years after laser intervention showed sustainability of the treatment.
