A minimally invasive modified technique for female stress urinary incontinence: transobturator tape without paraurethral dissection.

IntroductionMid-urethral slings, including transobturator tape (TOT), tension-free vaginal tape (TVT), tension-free vaginal tape-obturator (TVT-O), and a single incision sling, are the most popular procedures for the treatment of stress urinary incontinence (SUI). Although the classical TOT procedure is a minimally invasive technique, we believe that this technique can be further improved.AimTo determine whether there was a difference in success and complication rates between the classical TOT technique and a novel technique called “modified transobturator tape” (mTOT), which avoids periurethral dissection.Material and methodsIn total, 98 patients who underwent incontinence surgery between July 2011 and January 2017 were recruited for this prospectively planned study. Of the 98 patients, 47 patients underwent classical TOT, and 51 patients underwent the new mTOT procedure. Incontinence Impact Questionnaire-7 (IIQ-7) and visual analogue scale (VAS) scores were obtained preoperatively and postoperatively. Average or serious symptomatic scores in IIQ-7 were considered as subjective failure.ResultsNerve damage, vascular damage, retropubic hematomas, and bladder-urethra erosion were not observed in either group. There were no significant between-group differences in IIQ-7 scores. There were also no between-group differences in postoperative 1-month, 6-month, and 1-year VAS scores, but postoperative first day scores of the mTOT group were significantly lower than those of the classical TOT group (p < 0.05).ConclusionsThe proposed modified technique provides the same efficiency and reliability as the classic technique but is more advantageous in terms of reduced pain and resumption of earlier sexual activity.

Tomographic changes in eyes with hyperopic shift after triple Descemet membrane endothelial keratoplasty

To describe the tomographic changes in eyes with a hyperopic shift after triple Descemet membrane endothelial keratoplasty (DMEK). Private cornea practice, Blue Ash, Ohio, USA. Retrospective case series. Patients who had previous triple DMEK with preoperative and postoperative Scheimpflug corneal tomography (Pentacam) measurements and corresponding manifest refraction measurements were reviewed. Eyes with and without a hyperopic postoperative shift were compared at either the 1-month or 3- to 6-month follow-ups. Assessed parameters included demographics, cataract testing, visual acuity, manifest refraction, and Scheimpflug tomography data. Sixty-two eyes of 47 patients (21 men, 26 women) with Fuchs endothelial corneal dystrophy were included. Preoperative posterior flat keratometry (K), posterior steep K, posterior average K, central pachymetry, and asphericity (Q value) of the posterior cornea were significantly different when comparing the hyperopic and non-hyperopic group. At the postoperative 1-month and 3- to 6-month follow-ups, there was a significant between-group difference in change in postoperative anterior K (average), posterior K (average), central pachymetry, and posterior Q values compared with preoperative values. The combined preoperative criteria of posterior flat K (≥-5.25), central pachymetry (≥670μm), and posterior Q value (≥0.5) had a sensitivity of 58% (11/19 correctly identified hyperopic shifts) and specificity of 81% (8/43 incorrectly identified). Eyes with a hyperopic surprise after triple DMEK demonstrated a significant change in posterior and anterior corneal curvature compared with eyes without a hyperopic surprise. This might be secondary to corneal edema because these eyes also demonstrated greater preoperative corneal pachymetry.

Clinical Investigation on CT guided cryoablation for treating invasive chest wall or pleural tumors

Objective: To evaluate the feasibility and short-term effect of CT guided cryoablation for malignant chest wall or pleural involvement. Methods: To follow up 22 patients with chest wall or pleural involvement of various malignancies who underwent cryoablation from January 2012 to January 2015 by conducting postoperative 1-, 3- and 6-month enhanced CT, MRI or PET-CT examinations, respectively, evaluate local curative effect, and observe their progression-free survival (PFS), postoperative pain remission and complications after the cryoablation. Results: A total of 22 patients with 27 lesions received 26 times of argon-helium cryoablation. According to the coverage situation of immediate postoperative ice balls on the lesions, they were divided into a complete coverage group (Group A with 18 patients) and a partial coverage group (Group B with 4 patients). 1 month later, 15 patients' tumors were completely ablated, and 3 had residue and thus received the second cryoablation in Group A, while all patients' tumors had residue in Group B. 3 months later, 17 patients' tumors were completely ablated, and 1 had residue and thus received another cryoablation in Group A, while all patients' residual tumors enlarged in different extent in group B. 6 months later, all lesions were ablated in group A while all patients' residual tumors enlarged in group B. For the 22 patients, their preoperative, and postoperative 1-week, 1-month, 3-month, and 6-month VAS scores were 4.95±0.57, 1.45±0.35, 1.45±0.35, 1.64±1.71, and 2.00±2.35, respectively. The differences in the preoperative, postoperative 1-week, and postoperative 1-month scores are significant statistically (P<0.05), and the difference in the postoperative 1-month and 6-month scores is also with statistical significance (P=0.03). For all patients, their post-operative 1-week, 1-month, 3-monte and 6-month pain remission rates are 90.9%(20/22), 90.9%(20/22), 86.4% (19/22)and 81.8%(18/22), respectively. With a median follow-up of 13.5 months, the median PFS is 7 months. The adverse effect after argon-helium cryoablation involved transitory worsened pain (16 cases), pleural effusion (5 cases, including 3 underwent closed drainage), fever (5 cases), and hemoptysis (3 cases). Conclusion: CT guided argon-helium cryoablation is a safe and effective method to treat malignant chest wall or pleural involvement.

Effectiveness of Headless Bioabsorbable Screws for Fixation of the Scarf Osteotomy.

Scarf osteotomy has been used in hallux valgus surgery due to its large fixation surface for screws and low postoperative complications. However, screws may cause skin irritation from their head, which may require an additional surgical procedure to remove. This study included 115 patients (106 females and 9 males, 115 feet) who underwent hallux valgus correction with a scarf osteotomy using bioabsorbable screws between September 2010 and September 2012. Preoperative and postoperative 1-month and 1-year radiographic measurements, including intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), proximal phalangeal articular angle (PPAA), and lateral translational distance (LTD), were obtained. American Orthopaedic Foot & Ankle Society (AOFAS) hallux/forefoot scores were used for patient satisfaction. Preoperative mean values of HVA, IMA, and PPA of 32.8 degrees, 14.6 degrees, and 7.52 degrees, respectively, improved to 10.7 degrees, 6.0 degrees, and 4.6 degrees, respectively at 1-year follow up (P < .05). The difference in LTD between the 1-month and 1-year follow-up was not statistically significant. AOFAS hallux/forefoot score improved from 69.1 to 96.1 at the 1-year follow up (P < .001). Complete screw absorption was not seen radiographically. Sixteen feet had complications reported. One patient complained of skin irritation over a small protrusion of the screw, and another patient had a foreign body reaction. There were 3 patients with neurologic injury from a popliteal block and 3 patients with dorsal cutaneous nerve symptoms. Four feet had metatarsal fracture during surgery. We found the scarf osteotomy using bioabsorbable screws to have satisfactory clinical and radiographic results with a low complication rate. Level IV, case series.

Analysis of Temporal Change in Voice Quality After Thyroidectomy: Single-institution Prospective Study

This study analyzed the temporal changes of voice quality after thyroidectomy and assessed the predictive perioperative parameters of postthyroidectomy voice disorder (PTVD). This is a prospective cohort study. From March 2011 to July 2014, 559 patients who underwent thyroidectomy with or without central neck dissection were prospectively enrolled. All patients underwent prospective voice evaluation using the subjective and objective comprehensive battery of assessments, preoperatively and postoperatively at 1 week, 1 month, 3 months, 6 months, and 12 months. Fundamental frequency (F0) was not significantly decreased during the postoperative follow-up. Maximal vocal pitch (MVP) and maximal intensity were not recovered, even at 1 year postoperatively, whereas the Grade, Roughness, Breathiness, Asthenia, Strain scale reached preoperative value at postoperative 3-6 months and voice handicap index at 1 year. Postoperative 1-month MVP was the best predictor for PTVD, and the cut-off value was 80% of preoperative value. Wide surgical extent and high preoperative F0 were the parameters that significantly correlated with PTVD (P = 0.021 and P < 0.001, respectively), and large tumor, higher preoperative MVP, and lower postoperative 1-month F0 were significantly associated with permanent PTVD (P = 0.028, P < 0.001, and P = 0.003, respectively). Different recovery patterns of voice parameters should be considered in preoperative counseling. Intensive voice therapy may be needed for patients with the ability to produce higher pitch than normal preoperatively and wide surgical extent.

Phacoemulsification versus Laser Peripheral Iridotomy in Early Treatment of Acute Primary Angle-Closure Glaucoma

Purpose: We compared the outcomes of laser iridotomy and primary phacoemulsification when treating acute angle-closure glaucoma. Methods: This study was conducted with 61 patients diagnosed with acute angle closure glaucoma from January, 2005 to January, 2015. The patients received either laser iridotomy or primary phacoemulsification. The age and gender of each patient, differences of intraocular pressure (IOP) before and after treatment, visual acuity, need for IOP lowering agents and complications were analyzed retrospectively at 1-day, 1-month, 6-month and 12-month after the treatment. Patients who received laser iridotomy with phacoemulsification or trabeculectomy were excluded from this study. Additionally, we included only cases in which treatments were given within 3 days after the onset of symptom. Results: Among the 61 patients, 45 patients received laser iridotomy and 16 patients received primary phacoemulsification. One day after the treatment the laser iridotomy group showed better outcome in their visual acuity (log MAR 0.62 ± 0.51; p = 0.048). At 6-month postoperatively, the primary phacoemulsification group showed better visual acuity (log MAR 0.07 ± 0.15; p = 0.013). However, at 12-month postoperatively, the visual acuities were not significantly different between the 2 groups. Regarding IOP, at postoperative 1-month, the group of primary phacoemulsification shows significantly lower IOP (9.5 ± 1.3 mm Hg), compared with the group of laser iridotomy. A significant difference was observed in the number of IOP lowering agents that patients at 12 month after the treatment. There were no severe complications in either group. Conclusions: Following the initial treatment of acute angle-closure glaucoma, the primary phacoemulsification showed no significant differences in postoperative visual acuity, IOP and complications compared to the outcomes of laser iridotomy. Additionally, the need for IOP lowering agents was less in the primary phacoemulsification groups at 1 year after the operation. J Korean Ophthalmol Soc 2016;57(2):290-295

Paralleling technique for frenectomy and oral hygiene evaluation after frenectomy.

Background:High frenum attachment is a very common problem in the population. Various conventional techniques are available which has certain disadvantages; in addition to that high frenum also hinders oral hygiene maintenance. This study aims to evaluate patient's response to two different frenectomy technique, and oral hygiene maintenance before and after frenectomy.Materials and Methods:Twenty patients with high labial frenum were randomly selected from the outpatient department. Patients were divided into two groups according to the technique used. Each group contained ten patients. One group was treated by “conventional scalpel technique” and other group by “new paralleling technique”. To evaluate patients response, visual analogue scale for pain and speech were taken at first postoperative day, 1-week and 1-month. In other part of the study the oral hygiene maintenance was evaluated by using plaque and gingival bleeding index at baseline before frenectomy, 1-week and 1-month after frenectomy.Results:Results showed that new paralleling technique for frenectomy causes less postoperative discomfort and also there was significant improvement in the oral hygiene maintenance by the patient after frenectomy.Conclusion:High maxillary frenum causes hindrance in oral hygiene maintenance. Paralleling technique for frenectomy causes less discomfort to the patient during healing phase when compared with the conventional technique.

Pupil Diameter Changes in High Myopes after Collamer Lens Implantation.

ABSTRACTPurposeTo observe the changes in pupil size under photopic and scotopic conditions after Implantable Collamer Lens (ICL) implantations in eyes with high myopia.MethodsThe ICL was implanted in 90 eyes belonging to 45 patients with high myopia. Photopic pupil diameters, scotopic pupil diameters, anterior chamber depths, and ICL vaults were examined at the preoperative, postoperative 1-month, and postoperative 3-month stages. The preoperative and postoperative photopic pupil diameters and scotopic pupil diameters were also compared with each other to note the differences between them. The correlations between preoperative and postoperative pupil diameter changes under different light conditions and presurgical refractive error were analyzed alongside patient’s age and ICL vault.ResultsPupil diameters at both postoperative 1-month and postoperative 3-month stages were smaller than those before operation in distinct light environments, as well as pupil constriction amplitude. Correlation analysis showed that there was a statistically significant correlation between pupil diameter changes under different light conditions and presurgical refractive error at 1 month and 3 months after ICL implantation; pupil diameter decreased more when presurgical refractive error powers were less myopic. Statistically significant correlations were not found, however, with patient’s age and ICL vault. Postoperative 1-month and mean postoperative 3-month anterior chamber depths were decreased when compared with preoperative anterior chamber depths. Statistically significant correlations were found in change in preoperative and postoperative anterior chamber depth and ICL vault. No statistically significant difference was found between ICL vault at the postoperative 1-month and postoperative 3-month stages.ConclusionsPupil diameter may decrease at the 1- and 3-month stages after ICL implantation under both photopic and scotopic conditions. This indicates that reduction of pupil diameter may be caused by mechanical contact between the ICL and the posterior iris surface.

Prediction of outcome of radiofrequency ablation of the inferior turbinates

Radiofrequency ablation (RFA) of the turbinates is used commonly for nasal obstruction; however, there is no consensus on patient selection for this surgery. In a prospective clinical study, 53 adult subjects with bilateral turbinate hypertrophy were evaluated subjectively and objectively with anterior rhinomanometry at baseline and at 1, 3, and 6 months post-RFA of turbinates. RFA of the turbinates resulted in a significant decrease in predecongestant and postdecongestant visual analogue scale (VAS) scores and resistance measurements at postoperative months 1, 3, and 6 (p < 0.001 for all). Preoperative baseline subjective response to the decongestant showed a positive correlation with postoperative first month subjective and objective outcome (p < 0.05). Preoperative baseline objective response to the decongestant showed a highly significant correlation with postoperative 1-month, 3-month, and 6-month objective outcomes of surgery (p < 0.05 for all). Objective measures do not correlate with long-term subjective satisfaction even when the nose is objectively patent in subjects who underwent inferior turbinate RFA. The patients' long-term subjective benefit from RFA surgery cannot be estimated after a rhinomanometry with topical decongestion is performed. Performing a rhinomanometry with topical decongestion may help only to estimate the patients' objective benefit from RFA surgery.

Culture‐inappropriate antibiotic therapy decreases quality of life improvement after sinus surgery

Despite their widespread use, antibiotics have not been shown to improve chronic rhinosinusitis (CRS) outcomes. We aimed to determine whether culture-inappropriate postoperative antibiotic therapy was associated with less quality-of-life (QOL) improvement following functional endoscopic sinus surgery (FESS). This retrospective cohort study recruited 376 adult CRS patients undergoing FESS between October 1, 2007 to December 31, 2011. Patient demographics, comorbidities and medications were collected at baseline. Trimethoprim-sulfamethoxazole and clindamycin were administered for 2 weeks postoperatively. The antibiotic appropriateness was determined based on bacterial resistance profile of organisms identified during intraoperative culture. The QOL outcome was defined as change of 22-item Sinonasal Outcome Test scores from preoperative visit to 1-month, 3-month, and 6-month post-FESS. Clinically significant difference was defined as at least 0.5 standard deviations (SD) of baseline QOL score in the reference group. Mixed-effects regression models were performed. Seven percent of patients (n = 27) had culture-inappropriate antibiotic therapy, and additional 5% (n = 19) had culture-specific antibiotic adjustment. Compared to patients with culture-appropriate antibiotics, patients with culture-inappropriate antibiotics had significantly less improvement of QOL from baseline to postoperative 1-month and 3-month follow-up where the difference became clinically significant; patients with antibiotic adjustment had more QOL improvement from baseline to 1-month follow-up, but their QOL worsened at 3-month follow-up, and these changes were not clinically significant. However, all effects washed out at 6-month follow-up with no significant differences. Culture-inappropriate postoperative antibiotic therapy decreased short-term QOL improvement to a clinically meaningful level after FESS. Culture guided selection of antibiotics may improve short-term FESS outcome.

The change of contrast sensitivity of myopic patients after laser in situ keratomileusis

Objective To evaluate the contrast sensitivity function before and after laser in situ keratomileusis(LASIK).Methods With test chart,contrast sensitivity was measured in randomly selected 58 subjects(112 eyes)before,1 month and 3 months after LASIK.The contrast sensitivity was measured at 1.5,3.0,6.0,12.0 and 18.0 cycles per degree(c/d)spatial frequency respectively and comparison was made.Results The patients achieved the mean uncorrected visual acuity(UCVA) of 1.07 ±0.15 and 1.10±0.20 at postoperative 1-month and 3-months respectively.Which were close to the correct preoperative visual acuity.There was a general reduction in contrast sensitivity in all spatial frequencies at postoperative 1-month when they were compared with the preoperative contrast sensitivity.The difference at 6.0,12.0 and 18.0 c/d spatial frequency was statistically significant(P<0.01).By the 3-month visit,all eyes showed a recovery of contrast sensitivity function.Near contrast sensitivity in 6.0.12.0 and 18.0 c/d spatial frequency had a decline in superhigh myopia patients at 3-month(P<0.01).Conclusion Near contrast sensitivity became worse at the early stage after LASIK.It could be recovered later on.But that in super high myopia would take a longer recover time. Key words: laser in situ keratomileusis; myopia; contrast sensitivity

Nasal Displacement of a Tooth Root in a Dog

A ten-year-old miniature Dachshund dog was presented for chronic paroxysmal sneezing and unilateral nasal discharge. Extraction of the maxillary right fourth premolar tooth had been performed 2-weeks prior to the onset of clinical signs. Multiple diagnostic modalities were used to confirm the diagnosis and determine that the etiology was a nasally displaced mesiopalatal tooth root. A limited lateral rhinotomy was performed to remove the root. Postoperative examination 1-month following surgery indicated resolution of the clinical signs and uncomplicated healing of the surgery site. Oral examination indicated normal healing of the surgery site with continued absence of clinical signs 6-months after treatment.
