Protrusion In Patients Research Articles

Clinical Outcomes of Intravesical Prostatic Protrusion in Patients With Benign Prostatic Hyperplasia.

Background Benign prostatic hyperplasia (BPH) is a disorder that is characterized by the hyperplasia of the cellular elements of the prostate, leading to an enlarged prostate. One of the parameters affecting urinary outflow is intravesical prostatic protrusion (IPP). It is a phenomenon wherein the enlargement of the prostate protrudes into the bladder along the plane of least resistance. This condition can lead to various clinical effects, including symptoms such as the feeling of incomplete void and weak, interrupted urine stream. Hence, investigating the potential associations between different grades of IPP and clinical urological outcomes holds crucial implications for optimizing patient care, refining risk stratification, and enhancing treatment approaches. Methodology We examined patients who were following up at the urology outpatient clinics due to BPH between June 1, 2021, and December 31,2022. All patients included in this study were required to undergo a transabdominal prostate ultrasound. Patient records were reviewed for various factors, including demographic stratification, the presence of urine routine or culture with evidence of urinary tract infection (UTI) within the past two years, and whether patients were scheduled for surgical intervention. The radiological parameters were recorded by viewing the midsagittal and transverse ultrasound images retrospectively by two specialist radiology physicians. The parameters measured includedIPPGrade, prostate volume (PV), presence of bladder stones, anatomical abnormalities (such as bladder diverticulum), and post-void volume. Results The total sample size was 184 patients. Out of these, 53 (28.8%) had IPP Grade I, 72 (39.1%) were classified as Grade II, 42 (22.8%) had Grade III, and 17 (9.2%) were categorized as Grade IV. The data collected also showed that 12 (6.5%) patients had bladder stones on ultrasound examination. Additionally, 17 (9.2%) patients had bladder diverticulum. Furthermore, when controlled for age and PV, multivariate analysis using logistic regression models to calculate the odds ratio (OR) showed that increasing IPP Grade is associated with an increased risk of developing UTIs, acute urinary retention, and the need for surgical intervention. The highest risk group of patients is IPP Grade IV, with odds ratios (ORs) of 6.8, 7.2, and 6.4 for developing UTIs, experiencing acute urinary retention, and requiring surgical intervention, respectively. Conclusions The results provide compelling evidence of the adverse relationships between higher grades of IPP and worsening urological outcomes and patient morbidity.Hence, we recommend further studies be conducted on the clinical effects of IPP and that these measurementsshould be considered as part of routine ultrasound prostate imaging to aid in the management of BPH cases.

Correlation of multifidus degeneration with sex, age and side of herniation in patients with lumbar disc herniation

ObjectiveThe aim of this study was to determine the relationship between multifidus degeneration and sex, age and side of protrusion in patients with lumbar disc herniation(LDH).MethodsData were collected from September 2015 to September 2022 from patients with L4/5 and L5/S1 LDH. A total of 104 patients (62 males and 42 females) were included in this study, and there were 35 and 69 cases of L4/5 and L5/S1 LDH, respectively. Patients were divided into 4 groups according to age: group 1 (20–29), group 2 (30–39), group 3 (40–49) and group 4 (50–59). Magnetic resonance spectroscopy analysis was used to observe the fat fraction (FF) and functional cross-sectional area (f-CSA) of the defatted multifidus muscle of the protruding side (affected side) and the nonprotruding side (healthy side) of the L4/5 and L5/S1 gaps to evaluate the relationship between multifidus degeneration and sex, age and protruding side in patients with LDH.ResultsBetween sexes, the FF of the multifidus muscle was significantly greater in women than in men, regardless of whether it was on the affected or healthy side of the L4/5 segment or on the affected or healthy side of the L5/S1 segment (P < 0.05). Between age groups, there was a significantly positive relationship between the change in FF (%) of the multifidus muscle in patients with LDH and age, with increasing fatty infiltration of the multifidus increasing with age (P < 0.05); notably, there was a significant difference between group 4 and the remaining three groups but no significant difference between groups 1, 2 and 3. The f-CSA of the multifidus (cm2) was negatively correlated with age, with the f-CSA of the multifidus becoming more atrophic with increasing age; specifically, there was a significant difference between group 1 and the other three groups (P < 0.05) but not between groups 2, 3 and 4. Regarding the side of the herniated disc, (1) the differences in FF and f-CSA at the L4/5 and L5/S1 levels were not statistically significant between the affected side and the healthy side in patients with lumbar disc herniation at the L4/5 segment (P > 0.05); (2) the differences in FF and f-CSA at the L5/S1 level were not statistically significant between the affected side and the healthy side in patients with LDH at the L5/S1 segment (P > 0.05); (3) the difference between FF at the L4/5 level and f-CSA and FF at the L5/S1 level was not statistically significant (P > 0.05); and (4) the f-CSA at the L5/S1 level was significantly greater on the healthy side than on the affected side (P < 0.05).ConclusionThe proportion of lipoatrophy in female patients with L4/5 and L5/S1 disc herniations was greater than that in male patients. Lipoatrophy of the multifidus muscle increased with age and was significantly worse in patients over 50 years of age. The f-CSA of the multifidus muscle was negatively related to age, and the f-CSA of the multifidus muscle became more atrophic with increasing age. A comparison of degeneration showed no significant difference between the L4/5 patients and the L5/S1 patients in terms of f-CSA atrophy on the affected side of the herniated disc compared to the healthy side.

The surgical outcomes of anterior segmental osteotomy in Asian skeletal class II patients.

Anterior segmental osteotomy (ASO) following the surgery-first approach is a long-established treatment modality to resolve lip protrusion in patients with skeletal class II patterns. However, the indications and effectiveness of ASO still remain uncertain. The objective of this study is to investigate the effectiveness of ASO in Asian skeletal class II patients by evaluating the skeletal and soft tissue changes and analyzing pre-treatment variables that determine successful outcomes in occlusal as well as esthetic aspects. The lateral cephalograms of 44 skeletal class II patients who underwent ASO and orthodontic treatment for resolving lip protrusion were retrospectively collected. Hard and soft tissue variables of two groups, normalized (NG) and unnormalized (UNG) ANB after treatment were compared and analyzed. The rotational effect of the anterior segment on the hard and soft tissue was also investigated. ASO was successful in correcting the skeletal class II relationship and lip protrusion (ΔANB - 2.3°, 4-5mm lips retraction) in most cases. However, for patients with severely camouflaged skeletal class II incisors involving a large ANB and SNA, a large ANB still remained post-treatment. The study also found that rotation of the upper and lower anterior segments further augmented the amount of lip retraction. ASO was found to successfully correct ANB of skeletal class II patients under the following conditions (ANB 5.3° ± 1.5°, SNB 77.3° ± 4.5°, U1 to FH 115° ± 7.5, L1 to FH 48.0° ± 4.6). However, patients with larger ANB and SNA values may require bi-maxillary surgery. In addition, ASO has limitations in correcting gummy smile in cases of extreme maxillary excess. For patients requiring a large amount of lip retraction, rotation of the anterior segment may be beneficial in conjunction with bi-maxillary surgery.

Safe femoral condyle range for the reverse Rigidfix femoral fixation device in anterior cruciate ligament reconstruction

BackgroundTo determine the characteristics of cross-pin protrusion in patients treated with the reverse Rigidfix femoral fixation device for femoral tunnel preparation through the anteromedial portal in Arthroscopic anterior cruciate ligament reconstruction (ACLR), analyse the reasons for this outcome, and identify safety hazards of this surgical technique for improvement.MethodsA retrospective analysis of patients who underwent ACLR using this technology at our hospital in 2018 was conducted. Patients with and without cross-pin protrusion were included in the protrusion positive and negative groups, respectively. The sex, age and imaging characteristics of the patients with cross-pin protrusion were identified, and the reasons for cross-pin protrusion were analysed.ResultsThere were 64 and 212 patients in the protrusion positive and negative groups, respectively. The proportion of cross-pin protrusion cases was 23.19% (64/276). There was a significant difference in the ratio of males to females (P < 0.001, χ2 = 185.184), the mediolateral femoral condyle diameter (protrusion positive group, 70.59 ± 2.51 mm; protrusion negative group, 82.65 ± 4.16 mm; P < 0.001, t = 28.424), and the anteroposterior diameter of the lateral femoral condyle (protrusion positive group, 58.34 ± 2.89 mm; protrusion negative group, 66.38 ± 3.53 mm; P < 0.001, t = 16.615). The cross-pins did not penetrate the lateral femoral condyle cortex in patients with a mediolateral femoral condyle diameter ≥ 76 mm, but the cross-pins definitely penetrated the cortex when the diameter was ≤ 70 mm. The cross-pins did not penetrate when the anteroposterior lateral femoral condyle diameter was ≥ 66 mm, but the cross-pins definitely penetrated it when the diameter was ≤ 59 mm.ConclusionThe patients with cross-pin protrusion after reverse Rigidfix femoral fixation treatment to prepare the femoral tunnel through the anteromedial portal in ACLR were mainly females with small femoral condyles. For patients with a mediolateral femoral condyle diameter ≥ 76 mm and an anteroposterior lateral femoral condyle diameter ≥ 66 mm, there is no risk of cross-pin protrusion, so this technique can be used with confidence.Levels of evidenceIII.

The determinants and significance of intraluminal stent protrusion in patients with acute myocardial infarction

Abstract Background The mchanisms leading to intraluminal stent protrusion in patients following primary coronary angioplasty for ST-elevation myocardial infarction (STEMI) are not fully elucidated. Purpose We sought to investigate composition of stent protrusion, its systemic and local determinants as well as its consequences for epicardial blood flow restoration in STEMI patients. Methods We enrolled 85 STEMI patients with median age 61 (interquartile range 54–69) years. In all patients optical coherence tomography of an infarct-related artery was performed first following epicardial blood flow restoration after aspiration thrombectomy and second after final stent deployment. On admission, besides standard laboratory investigations we measured calibrated automated thrombogram parameters including time to start clotting, time to peak thrombin generation, peak thrombin generation and endogenous thrombin potential as well as ex vivo measured fibrin clot permeability reflecting fibrin pore size and fibrin clot lysis time. Results A median volume of stent protrusion was 13.4 (8.5–25.4) mm3 while atherothrombotic burden defined as a ratio of free intraluminal thrombus and tissue protrusion divided by stent volume was 6 (3.9–7.5)%. The main component of stent protrusion was lipid tissue in 32 (37.6%), fibrous tissue in 27 (31.8%) and thrombus in 26 (30.6%) patients. A volume of stent protrusion was correlated with total stent volume (R=0.79, P&amp;lt;0.001) and the length of lipid reach pool in the naïve coronary vessel intima (R=0.31, P=0.007) whereas atherothrombotic burden was correlated with residual thrombus volume before stent implantation (R=0.34, P=0.003), arcus of maximal lipid reach pool in the naïve coronary vessel intima (R=0.25, P=0.03) and stent area (R=0.26, P=0.02). The residual thrombus volume after aspiration thrombectomy was correlated with clot permeability (R=0.024, P=0.04) and inversely correlated with time to peak thrombin generation (R=−0.23, P=0.04). A temporary deterioration of epicardial blood flow of at least 1 point in Thrombolysis in Myocardial Infarction scale following stent implantation detected in 20 (23.5%) patients was associated with shorter lag time (3.0 [2.7–3.3] vs. 3.3 [3.0–4.0] min, P=0.015), shorter time to peak thrombin generation (5.7 [5.3–6.1] vs. 6.3 [5.7–7.1] min, P=0.026) and more frequent presence of lipid-rich stent protrusion (65 vs. 29%, P=0.007) as compared to the patients without slow-flow phenomenon after stent deployment. Conclusions The total volume of stent protrusion is correlated with local determinants including stent size and lipid content in the naïve coronary artery intima. After adjustment for stent volume, atherothrombotic burden is additionaly affected by residual thrombus volume after aspiration thrombectomy. However, patients with faster thrombin formation and lipid-rich stent protrusion are more prone to slow-flow phenomenon following stent implantation.

RELATION OF TOTAL CHOLESTEROL TO PROSTATE VOLUME AND INTRAVESICAL PROSTATIC PROTRUSION IN BENIGN PROSTATIC HYPERPLASIA PATIENTS

Objective: To determine the relationship between total cholesterol, prostate volume, and intravesical prostatic protrusion in patients with benign prostatic hyperplasia. Material &amp; Methods: This study used a cross-sectional method, carried out at the Paru and Bina Sehat Hospital in Jember. The sample in this study was BPH patients who met the inclusion criteria taken through medical record data from October 2019 to January 2020 Results: Samples on this study amounted to 33 patients. In this study, there was a difference between normal and high cholesterol with prostate volume in BPH patients (p = 0.00) and there was a significant relationship between cholesterol and prostate volume with strong correlation strength (p = 0.00 and r = 0.751) while the difference between high and normal cholesterol with IPP obtained insignificant results (p = 0.211) and the correlation between cholesterol and IPP obtained an insignificant relation with weak correlation strength (p = 0.217 and r = 0.221). Conclusion: There is a significant relationship between total cholesterol and prostate volume and a significant difference in prostate volume between normal and high total cholesterol in BPH patients, while there is no significant result between total cholesterol and intravesical prostatic protrusion in BPH patients.

A new radiological measurement method used to evaluate the modified transconjunctival orbital fat decompression surgery

PurposeA new radiological method was used to evaluate the plastic effect of modified transconjunctival orbital fat decompression surgery in patients with inactive thyroid-associated ophthalmopathy.MethodsIn this study, 10 inactive patients (14 eyes) with moderate to severe thyroid-associated ophthalmopathy were selected. The patients underwent modified transconjunctival orbital fat decompression surgery. According to the results of a spiral CT scan before and 6 months after the surgery, the INFINITT system workstation was used to measure the eyeball protrusion value. According to the results obtained by the PHLIPS IntelliSpace Portal elliptical area and line segment measurement tools, the standard elliptical vertebral volume formula was used to calculate the muscular cone inner volume. Changes in eyeball protrusion and the inner volume of the muscular cone before and after surgery were examined. Statistical analysis of the correlation between the two parameters was performed.ResultsRadiological measurement results confirmed that removing the orbital fat in the muscle cone during surgery was effective for alleviating eyeball protrusion in patients with thyroid-associated ophthalmopathy (P < 0.05). This surgery caused an obvious change in the muscle cone inner volume (P < 0.05). And there was significant correlation between changes in eyeball protrusion and muscle cone inner volume (r = 0.797, P = 0.0006, P < 0.05).ConclusionThe radiological assessment method used in this study is simple and easy to implement. For inactive patients with moderate to severe thyroid-associated ophthalmopathy who just want to improve their appearance, the modified orbital fat decompression surgery is worth considering.

Efficacy of Lycopene in the Treatment of Oral Submucous Fibrosis: A Meta-analysis of Randomized Controlled Trials

ObjectivesThe aim of this meta-analysis was to systematically evaluate the efficacy of lycopene in improving maximum mouth opening and other clinical symptoms in patients with oral submucous fibrosis (OSF). MethodsWe searched 5 databases: PubMed, Web of Science, Embase, The Cochrane Library, and EBSCO. Randomized controlled trials were collected to evaluate the efficacy of lycopene in the treatment of OSF. Each database was searched from inception to April 30, 2019. The RevMan 5.3 software was used for this meta-analysis. ResultsThe included studies were 7 randomized controlled trials involving 758 patients with OSF. The results of this meta-analysis showed that lycopene was significantly more effective in improving maximum mouth opening in OSF patients than placebo treatment (mean difference [MD]: 3.15; 95% confidence interval [CI]: 2.19-4.10, P < .0001, I2 = 0%). Compared with control groups, lycopene could significantly increase the maximum mouth opening in patients with OSF after 1 month of treatment (MD, 2.40; 95% CI, 2.22-2.58; P = .91; I2 = 0%), 2 months of treatment (MD, 3.19; 95% CI, 2.87-3.51; P = .93; I2 = 0%), and 3 months of treatment (MD, 4.89; 95% CI, 4.51-5.28; P = .86; I2 = 0%). However, no significant difference was found in alleviation of burning sensation after 1 month (risk ratio [RR], 1.04; 95% CI, 0.89-1.23; P = .73; I2 = 0%), 2 months (RR, 0.98; 95% CI, 0.73-1.31; P = .69; I2 = 0%), and 3 months of treatment (RR, 0.84; 95% CI, 0.47-1.52; P = .81; I2 = 0%); tongue protrusion (MD, −1.59; 95% CI, −4.15 to 0.97; P = .12; I2 = 58%); and pain associated with the lesion after 1 month (RR, 1.05; 95% CI, 0.92-1.21; P = .77; I2 = 0%), 2 months (RR, 0.95; 95% CI, 0.75-1.19; P = .35; I2 = 0%), and 3 months (RR, 0.95; 95% CI, 0.68-1.33; P = .14; I2 = 51%) in patients with OSF between lycopene and control groups. ConclusionsThe results of this meta-analysis showed that lycopene is more effective for improving symptoms of maximum mouth opening than placebo groups and control groups, but there were no significant differences in burning sensation, pain associated with lesion, and tongue protrusion in patients with OSF compared with control groups.

The Effect of Intravesical Prostatic Protrusion in Patients with Benign Prostatic Hyperplasia: Controlled, Clinical Study

Background: Although prostate cancer releases more prostate-specific antigen (PSA) per unit of prostate volume (PV), data are limited regarding the association between intravesical prostatic protrusion (IPP) and the PSA level. Objectives: The study aim was to evaluate the IPP effect in patients with benign prostatic hyperplasia. Method: This study included patients with (n = 119) and without (n = 121) IPP. The age, International Prostate Symptom Score (IPSS), PSA level, maximum and average flow rates, PV, hematuria, urinary retention, and post-void residual (PVR) volume were compared between the 2 groups. Results: The mean ages were similar between the 2 groups (66.56 ± 8.67 and 66.92 ± 8.7 years, respectively, p = 0.747), and there were no statistically significant differences in the IPSS, maximum and average flow rates, hematuria, PVR volume, and urinary retention means (p > 0.05). However, the IPP patients had lower total PSA (tPSA) and free PSA (fPSA) levels than those without IPP (3.55 [4.18] vs. 5.26 [5.24] ng/mL, p = 0.013 and 0.7 [1.09] vs. 1.05 [1.23] ng/mL, p = 0.029, respectively). Moreover, there were strong positive correlations between the IPP grade and the tPSA and fPSA levels (r = 0.262, p = 0.001 and r = 0.254, p = 0.002 respectively). Conclusions: This study demonstrated that IPP results in a decreased PSA level, even with a higher PV.

Prospective Assessment of Maximum Protrusion in Patients Wearing a Mandibular Advancement Device

Prospective Assessment of Maximum Protrusion in Patients Wearing a Mandibular Advancement Device

Association between metabolic syndrome and intravesical prostatic protrusion in patients with benign prostatic enlargement and lower urinary tract symptoms (MIPS Study).

To investigate the association between metabolic syndrome (MetS) and morphological features of benign prostatic enlargement (BPE), including total prostate volume (TPV), transitional zone volume (TZV) and intravesical prostatic protrusion (IPP). Between January 2015 and January 2017, 224 consecutive men aged >50 years presenting with lower urinary tract symptoms (LUTS) suggestive of BPE were recruited to this multicentre cross-sectional study. MetS was defined according to International Diabetes Federation criteria. Multivariate linear and logistic regression models were performed to verify factors associated with IPP, TZV and TPV. Patients with MetS were observed to have a significant increase in IPP (P < 0.01), TPV (P < 0.01) and TZV (P = 0.02). On linear regression analysis, adjusted for age and metabolic factors of MetS, we found that high-density lipoprotein (HDL) cholesterol was negatively associated with IPP (r = -0.17), TPV (r = -0.19) and TZV (r = -0.17), while hypertension was positively associated with IPP (r = 0.16), TPV (r = 0.19) and TZV (r = 0.16). On multivariate logistic regression analysis adjusted for age and factors of MetS, hypertension (categorical; odds ratio [OR] 2.95), HDL cholesterol (OR 0.94) and triglycerides (OR 1.01) were independent predictors of TPV ≥ 40 mL. We also found that HDL cholesterol (OR 0.86), hypertension (OR 2.0) and waist circumference (OR 1.09) were significantly associated with TZV ≥ 20 mL. On age-adjusted logistic regression analysis, MetS was significantly associated with IPP ≥ 10 mm (OR 34.0; P < 0.01), TZV ≥ 20 mL (OR 4.40; P < 0.01) and TPV ≥ 40 mL (OR 5.89; P = 0.03). We found an association between MetS and BPE, demonstrating a relationship with IPP.

Axial four-dimensional computed tomographic images to analyze crosswise differences in protrusive condylar movement in patients who underwent mandibulectomy and free flap reconstruction

ObjectiveFew studies evaluate condylar movement following mandibular reconstruction. The main objective of this study was to show that axial four-dimensional computed tomography (4DCT) could visualize bilateral protrusive condylar movement directly. We used axial 4DCT images to assess condylar protrusion in patients who underwent mandibular reconstruction. MethodsWe enrolled seven healthy volunteers (median age 30 years, range 27–38 years) and seven patients (median age 65 years, range 52–80 years), who underwent mandibulectomy (segmental in five, hemi in one, marginal in one) and free flap reconstruction (using the fibula in six and the radial forearm in one). Six study subjects were instructed to masticate a cookie during the 4DCT scan (the seventh made chewing motions). The distance between the most anterior and posterior positions of the bilateral condyles on 4DCT (axial view) images was then measured and compared between controls and patients using the Mann–Whitney U-test. ResultsThe crosswise difference in the distances of condylar protrusion was significantly greater in patients than in the controls. ConclusionAxial 4DCT images can visualize a bilateral condylar protrusive path. Axial 4DCT images for patients who have undergone mandibulectomy and reconstruction may be useful for evaluation of functional movement of condyles.

Clinical Impact of Suboptimal Stenting and Residual Intrastent Plaque/Thrombus Protrusion in Patients With Acute Coronary Syndrome: The CLI-OPCI ACS Substudy (Centro per la Lotta Contro L'Infarto-Optimization of Percutaneous Coronary Intervention in Acute Coronary Syndrome).

Clinical consequences of optical coherence tomographic (OCT) high-definition visualization of plaque/stent structures in acute patients remain undefined. In this retrospective substudy, we assessed the prognostic impact of postprocedural culprit lesion OCT findings in patients with acute coronary syndrome undergoing percutaneous coronary intervention. In the CLI-OPCI (Centro per la Lotta Contro L'Infarto-Optimization of Percutaneous Coronary Intervention) database collecting cases from 5 independent OCT-experienced centers, we retrospectively analyzed postprocedural OCT findings in acute coronary syndrome patients and explored its possible impact (specifically that of residual intrastent plaque/thrombus protrusion) on outcome. From 2009 to 2013, 507 patients (588 lesions) were evaluated. Patients experiencing device-oriented cardiovascular events showed more frequently the features of suboptimal stent implantation defined as the presence of significant residual intrastent plaque/thrombus protrusion (hazard ratio [HR], 2.35; P<0.01), in-stent minimum lumen area (MLA) <4.5 mm2 (HR, 2.72; P<0.01), dissection >200 µm at distal stent edge (HR, 3.84; P<0.01), and reference lumen area <4.5 mm2 at either distal (HR, 6.07; P<0.001) or proximal (HR, 8.50; P<0.001) stent edges. Postprocedural OCT assessment of treated culprit lesion revealed at least one of these parameters in 55.2% of cases, with an associated increased risk of device-oriented cardiovascular events during follow-up (17.9% versus 4.8%; P<0.001). Both the presence of at least one of these parameters (HR, 3.69; P=0.002) and the residual intrastent plaque/thrombus protrusion (HR, 2.83; P=0.008) were confirmed as independent predictors of device-oriented cardiovascular events. In this retrospective study of acute coronary syndrome patients undergoing percutaneous coronary intervention, a composite of OCT-defined suboptimal stent implantation characteristics at the culprit lesion and residual intrastent plaque/thrombus protrusion was associated with adverse outcome.

Removal of symptomatic titanium fixation plates after craniotomy.

Titanium fixation plates are routinely used for rigid fixation of bone flaps after craniotomy. In craniofacial surgery or after craniotomy involving orbitozygomatic osteotomies, these plates are occasionally removed because of infection, pain, protrusion, soft tissue erosion, and plate malfunction. However, plate removal because of pain and protrusion after craniotomy without orbitozygomatic osteotomy has rarely been reported. A retrospective analysis of all patients who underwent removal of cranial fixation plates after craniotomy, performed by the senior authors at one institution between 2014 and 2016, was conducted. A total of 319 patients underwent bone flap fixation after craniotomy using cranial fixation plates between 2014 and 2016. Five of those patients (1.6%) had their cranial plates removed because of pain and protrusion. An additional four patients had a cranial fixation plate removed during that time frame with the original craniotomy performed before 2014. All nine patients had immediate resolution of symptoms after plate removal. We report our experience with cranial fixation plate removal because of pain and protrusion in patients who underwent craniotomy without orbitozygomatic osteotomy, particularly frontotemporal craniotomy. In an attempt to reduce this complication, we recently stopped placing a full-size burr hole in the keyhole area of a frontotemporal craniotomy, eliminating the need for a titanium burr hole cover plate.

Combined inguinal hernia in the elderly. Portraying the progression of hernia disease

IntroductionIdentification of a combined hernia is a common occurrence in the course of inguinal hernia repair. This type of protrusion disease seems to affect the elderly, in particular. Very few investigations have been carried out to ascertain the structural changes that occur in the groin affected by this clinical condition. MethodAnalysis of intraoperative findings of combined inguinal hernias evidenced in the elderly, from the most recent 100 groin hernia repair procedures carried out by a single operator, represents the basis of the article. Protrusions that presumably represent the forerunner of this type of hernia were also analyzed: double ipsilateral inguinal hernias composed of a direct and an indirect protrusion. The gross anatomical, as well as histological, modifications occurring during the development of combined protrusions were also evaluated. ResultsCombined hernia was the most frequent protrusion in patients over 65 years, accounting for 36% of the total in this patient group. In the same patient cohort, double inguinal hernia further involves 22% of elderly subjects. Macroscopically, progressive disruption of the inguinal back wall and degenerative reabsorption of the inferior epigastric vessels were evidenced. Histologically, inflammatory infiltrate, significant nerve and vascular injuries, along with severe muscle degeneration were recognized. ConclusionsThe results seem to confirm that inguinal hernia is an unremitting progressive disease caused by chronic compressive structural damage. Combined hernias represent a frequent clinical condition in the elderly consequent to long-term degenerative damage. Therapy of combined protrusions must consider the impact of visceral vector forces.

Hemiglossectomy tongue reconstruction: Modeling of elevation, protrusion, and functional outcome using receiver operator characteristic curve.

The purpose of this study was to model >12 month speech and the oral phase of swallowing outcomes with the reconstructive metrics of tongue elevation and protrusion in patients reconstructed with the rectangle tongue template for a hemiglossectomy defect. We conducted a study using 40 surviving patients (23 men, 17 women) treated between 2000 and 2012. Statistically significant correlations of elevation and protrusion with functional outcomes were modeled with receiver operator characteristic (ROC) curves to understand the performance and reliability of the rectangle tongue reconstruction. Tongue elevation (1.8-1.9 cm) reliably produces best outcomes in nutritional mode, range of liquids, and ≥4/6 for range of solids. Greater tongue elevation (2.1-2.2 cm) reliably produces best outcomes for eating and speaking in public and understandability of speech. Tongue protrusion (0.8-1.0 cm) reliably produces best scores across all assessed outcomes except ≥4/6 for range of solids and ≥4/5 understandability of speech. ROC curves are useful for assessing reliability and relating reconstructive objectives to functional outcomes. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1066-1073, 2016.

Clinical Significance of Intravesical Prostatic Protrusion in Patients with Benign Prostatic Hyperplasia

INTRODUCTION: Intravesical prostatic protrusion is a morphological change due to excessive growth of the median and lateral lobes of the prostate into the bladder in benign prostatic hyperplasia. It causes a 'ball-valve' type of obstruction during voiding. It is a useful parameter to assess the severity of the disease process, selection of treatment modality and its possible outcome in benign prostatic hyperplasia.MATERIAL AND METHODS: A prospective, non-randomized, observational study was carried out from January 2014 to June 2014 in the Department of Urology, College of Medical Sciences, Nepal. Total of 50 patients with benign prostatic hyperplasia were evaluated to assess the correlation of intravesical prostatic protrusion with international prostate symptom score, prostate volume, maximum flow rate and post void residual urine. Correlation between parameters of interest was quantified with Pearson correlation test.RESULTS: A positive correlation was demonstrated between intravesical prostatic protrusion, international prostate symptom score, prostate volume and post void residual urine. There was a negative correlation between intravesical prostatic protrusion and maximum flow rate.CONCLUSION: Intravesical prostatic protrusion is correlated with international prostate symptom score, prostate volume, maximum flow rate, and post void residual urine volume and hence can be used to assess the severity of benign prostatic hyperplasia.Journal of Universal College of Medical Sciences Vol. 3, No. 1, 2015: 6-10

Closed versus open treatment of mandibular condylar process fractures: A meta-analysis of retrospective and prospective studies.

The treatment of fractures of the mandibular process remains controversial, although there is a trend towards open reduction and internal fixation. This study compared open and closed treatments and assessed the results with a meta-analysis. A literature search of PubMed found eight studies that met the search criteria and were included in the meta-analysis. The studies increasingly suggest better results for open treatment, in terms of mouth opening, protrusion, laterotrusion, pain, and malocclusion. In the meta-analysis, the outcome was significantly better for laterotrusion and protrusion in patients treated by open reduction and internal fixation. Due to the different study protocols and lack of information on classification, follow-up time, and inclusion criteria, comparison of the studies remains difficult and further prospective, randomized studies should examine these issues.

뇌성마비환자에서 가철성장치를 이용한 상악 전치부 돌출 완화 : 증례보고

14세 남환이 정기검진을 위해 내원하여 임상 구강검사 결과 상악 전치의 돌출과 상악궁 협착이 관찰되었다. 환아는 뇌성마비를 가지고 있었으나 간단한 설명을 이해하고 쉬운 지시를 수행할 수 있었으므로 가철성 장치를 이용한 교정치료를 시도하였다. 단계적이고 주의 깊은 접근을 통해 상악궁 협착 해소 및 상악 전치의 돌출을 완화할 수 있었다. 뇌성마비 환아의 경우 특징적으로 상악 전치의 돌출이 흔히 나타나는데, 이는외상의 위험에 쉽게 노출된다. 하지만 뇌성마비 환아에서 나타나는 특징적인 반사, 침 흘리기 습관, 행동조절의 어려움 등을 이유로 많은 임상의들이 교정 치료를 포기하게 된다. 적절한 환자 선정과 수행 가능한 치료목표를 세운다면, 뇌성마비 환아에서도 단계적이고 반복적인 행동조절과 약물을 이용하여 치료가 가능하다. 교정 치료를 통해 얻어진 상악 전치의 돌출 완화는 외상의 위험성을 줄이고 더 나은 심미성을 제공하는 긍정적인 효과를 가져오게 된다. 따라서 임상의들은 뇌성마비 환아의 치료에 대한 인식 변화 및 개선을 위한 적극적인 노력이 필요할 것이며, 뇌성마비 환아들은 더 나은 구강 건강을 영위할 수 있을 것이다. Cerebral palsy is one of the primary handicapping conditions of childhood. The prevalence of malocclusions in patients with cerebral palsy is approximately twice than in general population. Even though these high rates of malocclusions, most clinicians may feel uncomfortable about treating such problems to reduce inclination of anterior teeth because to reduce of protrusion makes to decrease risk of trauma. This is the case report about mitigation of maxillary anterior teeth protrusion in patient with cerebral palsy. A 14 year old boy who had cerebral palsy visited our dental hospital. He had severe protrusive maxillary anterior teeth and narrow arch form. He was experienced at using Castillo morales appliance in early childhood. He had mild mental retardation and was able to learn simple skills. He and his parents had willing to improve his dental problems. A gentle impression taking on maxilla was done. Removable appliance was made including median screw and labial bow. We provide a period of adaption for 3 weeks. After of anterior teeth through activation of labial bow was done once a month by dentist. The treatment carried out for 10 months and we could observe reduced labial inclination of maxillary right central incisor and more wide arch form. Hawley type retainer was set at maxilla for retention. In conclusion, accompanying careful case selection and treatment, patient with cerebral palsy can be treated and should not be ignored their orthodontic needs.
