The purpose of this study was to examine and compare the peak von Mises stress distributions in the crown, implant and abutment by using finite element analysis (FEA). Besides, a comparison of the implant-abutment connection types in the short implant with the FEA method was established. A short implant (4 × 5 mm) with a taper-lock connection and a regular implant (4 × 9 mm) with a screw connection were used in maxillary central incisor tooth area. Three different titanium abutments with 0?, 15? and 25? angles were used for abutments. In addition, in order to determine whether the stress change in short implants is due to the length of the implant-abutment connection, a screw was designed for a short implant and it was also evaluated in the same three angles. A total of three groups and nine models were generated. 114.6N load was applied to the cingulum area of the crown at an angle of 135? to the long axis of the crowns. A torque load of 25 Ncm was applied to the regular and short implant screw. Von Mises stress distributions of implants, abutments and crowns were evaluated by using FEA. Increased angle in implants increased von Mises stress values of implant, abutment and crown. Screw connection was found higher at all angles in short implants. Close values were found at different angles in taper-lock short implant crowns. The length and the angle in the bone of implant with the type of implant-abutment connection results in the accumulated stress values. Clinical Implications Taper implant-abutment connection system was found to be more promising in terms of stress accumulation in crowns. Although the amount of stress on the abutment increased due to the length of the implant in short implants, taper implant-abutment connection system slightly reduced related to this increase.展开更多

Fourteen patients (58 edentulous sites) with alveolar atrophy in the anterior maxilla were treated with autogenous block bone grafts. CBCT examinations were performed at 1 month before surgery (T0), immediately after surgery (T1), 3 to 4 months after surgery (T2), 6 to 7 months after surgery before implant placement (T3), 12 to 13 months after surgery (T4), and the longest follow-up point (T5). Alveolar crestal and basal bone width (ACBW, ABBW), and alveolar bone height (ABH) were measured and divided into IPS (30 sites) and NIPS (28 sites). All results were compared by the Wilcoxon Signed Rank test. The bone resorption changes for both groups were the same. For these three parameters, ACBW didn’t change significantly from T2 to T3 and T4 to T5, ABBW didn’t change at every period from T2 to T5, and ABH didn’t change from T4 to T5. The bone resorption volume of ACBW and ABH in NIPS were more than in IPS after implant placement surgery, while the volume of ABBW was similar in both groups. At T5, the bone resorption percentages of ACBW, ABBW, and ABH were 25.57%, 16.85% and 43.84% in IPS, and 33.55%, 15.92% and 46.44% in NIPS. A more rapid loss of alveolar crest in NIPS resulted from implant placement surgery, and this reminded us of the importance of immediate implant placement.展开更多

It has a heterogenous clinical presentation with varying degrees of severity correlated with specific central nervous system zones or areas, and its prognosis is uncertain. This case study describes a 62-year-old male patient with acquired brain damage of the anterior cingulate cortex as a result of an ischemic event in the territory of the left anterior cerebral artery. Cognitive function was assessed using the neuropsychological executive function and frontal lobe test battery (BANFE-2) as well as other neuropsychological tests. The results show a profile of higher mental functions characterized by the presence of dysexecutive syndrome with marked behavioral alteration and diencephalic amnesia. .展开更多

Methods: A sample of dental casts was obtained from 100 patients: 50 females and 50 males with an age range from 18 to 35 years. The sample was selected based on the criteria of intact maxillary anterior dental arches, free from imbrications and crowding, no restorations or replaced teeth in the upper front teeth. The width and length of the 600 upper anterior teeth included in the casts were measured, together with the combined upper anterior tooth width for each cast. Analysis of width/height ratio, sexual dimorphism, and golden proportions was statistically analyzed. The data was analysed by SPSS using one-sample t-test, two-sample t-test, and paired t-test. Results: Most measurements had a normal distribution. Paired sample t-test revealed that the average length of male maxillary incisors is significantly higher than female maxillary incisors, while there is no obvious difference in maxillary incisor width. The mean width/length ratio of maxillary incisors ranges from 0.78 to 0.87. The mean values of maxillary apparent tooth width prove that the golden proportion (GP) ratio 1.618 was absent in the current sample. The current study data shows that the mean values of tooth width and length differed from some other populations. Conclusions: Based on the findings of this research, there is no statistically significant difference in the maxillary anterior tooth dimensions for the right and left sides of the arch. Length and width dimensions of the central incisor (CI) were greater than those of lateral incisor (LI) and Canine (C) for both genders, suggesting CI to be the dominant anterior tooth. Some gender differences in tooth dimensions, with males tend to have longer tooth dimensions than females, the average width/length ratio of the female is higher than male, which confirms that the male tends to have longer teeth. The result shows the absence of golden proportion (GP) ratios suggesting that the Golden Proportion guideline was not applicable for the Hong Kong SAR population for either gender.展开更多

Anterior uveitis (AU) is the inflammation of the anterior uvea which is composed of the iris and the ciliary body. The objective of the study was to identify the epidemiological and etiological determinants of non-traumatic anterior uveitis at the Campus Teaching Hospital of Lomé. Materials and methods: Retrospective cross-sectional study of the records of patients diagnosed with anterior uveitis (AU) without a notion of trauma in the ophthalmology department of CHU Campus of Lomé from January 1, 2010 to December 31, 2019 (10 years). Results: 141 cases of uveitis, representing a prevalence of 0.18%. Female predominance, with a sex ratio of 0.76. Mean age was 34.74 ± 13.20 years. Decreased visual acuity was the primary complaint (34.40%), followed by ocular pain (28%). Non-traumatic anterior uveitis was unilateral in 87.2% of cases. Retro-corneal precipitates were present in all patients. 61.60% of patients had Tyndall in the anterior chamber. The etiology of non-traumatic AU was undetermined in 76.80% of cases. Toxoplasmosis, tuberculosis and syphilis were the main etiologies found. Conclusion: Non-traumatic anterior uveitis is relatively rare but serious, often affecting young subjects. It is a pathology that engages eye health professionals, not only because of the difficulties involved in diagnosing the etiology, but also because of its progression which sometimes leads to blindness.展开更多

文摘Although short implants are seen as alternative treatments that require additional surgical techniques in posterior region, they can be applied to anterior maxilla and various studies are required on this subject. The purpose of this study was to examine and compare the peak von Mises stress distributions in the crown, implant and abutment by using finite element analysis (FEA). Besides, a comparison of the implant-abutment connection types in the short implant with the FEA method was established. A short implant (4 × 5 mm) with a taper-lock connection and a regular implant (4 × 9 mm) with a screw connection were used in maxillary central incisor tooth area. Three different titanium abutments with 0?, 15? and 25? angles were used for abutments. In addition, in order to determine whether the stress change in short implants is due to the length of the implant-abutment connection, a screw was designed for a short implant and it was also evaluated in the same three angles. A total of three groups and nine models were generated. 114.6N load was applied to the cingulum area of the crown at an angle of 135? to the long axis of the crowns. A torque load of 25 Ncm was applied to the regular and short implant screw. Von Mises stress distributions of implants, abutments and crowns were evaluated by using FEA. Increased angle in implants increased von Mises stress values of implant, abutment and crown. Screw connection was found higher at all angles in short implants. Close values were found at different angles in taper-lock short implant crowns. The length and the angle in the bone of implant with the type of implant-abutment connection results in the accumulated stress values. Clinical Implications Taper implant-abutment connection system was found to be more promising in terms of stress accumulation in crowns. Although the amount of stress on the abutment increased due to the length of the implant in short implants, taper implant-abutment connection system slightly reduced related to this increase.
文摘The aim of this study was to compare the bone resorption differences between implant placement sites (IPS) and non-implant placement sites (NIPS) after autogenous block bone grafts in the anterior maxilla. Fourteen patients (58 edentulous sites) with alveolar atrophy in the anterior maxilla were treated with autogenous block bone grafts. CBCT examinations were performed at 1 month before surgery (T0), immediately after surgery (T1), 3 to 4 months after surgery (T2), 6 to 7 months after surgery before implant placement (T3), 12 to 13 months after surgery (T4), and the longest follow-up point (T5). Alveolar crestal and basal bone width (ACBW, ABBW), and alveolar bone height (ABH) were measured and divided into IPS (30 sites) and NIPS (28 sites). All results were compared by the Wilcoxon Signed Rank test. The bone resorption changes for both groups were the same. For these three parameters, ACBW didn’t change significantly from T2 to T3 and T4 to T5, ABBW didn’t change at every period from T2 to T5, and ABH didn’t change from T4 to T5. The bone resorption volume of ACBW and ABH in NIPS were more than in IPS after implant placement surgery, while the volume of ABBW was similar in both groups. At T5, the bone resorption percentages of ACBW, ABBW, and ABH were 25.57%, 16.85% and 43.84% in IPS, and 33.55%, 15.92% and 46.44% in NIPS. A more rapid loss of alveolar crest in NIPS resulted from implant placement surgery, and this reminded us of the importance of immediate implant placement.
文摘Stroke is a physiological alteration associated with changes in blood flow that can result in sudden-onset cognitive impairment. It has a heterogenous clinical presentation with varying degrees of severity correlated with specific central nervous system zones or areas, and its prognosis is uncertain. This case study describes a 62-year-old male patient with acquired brain damage of the anterior cingulate cortex as a result of an ischemic event in the territory of the left anterior cerebral artery. Cognitive function was assessed using the neuropsychological executive function and frontal lobe test battery (BANFE-2) as well as other neuropsychological tests. The results show a profile of higher mental functions characterized by the presence of dysexecutive syndrome with marked behavioral alteration and diencephalic amnesia. .

文摘BACKGROUND Dislocation rates after hemiarthroplasty reportedly vary from 1%to 17%.This serious complication is associated with increased morbidity and mortality rates.Approaches to this surgery are still debated,with no consensus regarding the superiority of any single approach.AIM To compare early postoperative complications after implementing the direct anterior and posterior approaches(PL)for hip hemiarthroplasty after femoral neck fractures.METHODS This is a comparative,retrospective,single-center cohort study conducted at a university hospital.Between March 2008 and December 2018,273 patients(a total of 280 hips)underwent bipolar hemiarthroplasties(n=280)for displaced femoral neck fractures using either the PL(n=171)or the minimally invasive direct anterior approach(DAA)(n=109).The choice of approach was related to the surgeons’practices;the implant types were similar and unrelated to the approach.Dislocation rates and other complications were reviewed after a minimum followup of 6 mo.RESULTS Both treatment groups had similarly aged patients(mean age:82 years),sex ratios,patient body mass indexes,and patient comorbidities.Surgical data(surgery delay time,operative time,and blood loss volume)did not differ significantly between the groups.The 30 d mortality rate was higher in the PL group(9.9%)than in the DAA group(3.7%),but the difference was not statistically significant(P=0.052).Among the one-month survivors,a significantly higher rate of dislocation was observed in the PL group(14/154;9.1%)than in the DAA group(0/105;0%)(P=0.002).Of the 14 patients with dislocation,8 underwent revision surgery for recurrent instability(posterior group),and one of them had 2 additional procedures due to a deep infection.The rate of other complications(e.g.,perioperative and early postoperative periprosthetic fractures and infection-related complications)did not differ significantly between the groups.CONCLUSION These findings suggest that the DAA to bipolar hemiarthroplasty for patients with femoral neck fractures is associated with a lower dislocation rate(<1%)than the PL.
文摘BACKGROUND Inflammatory myofibroblastic tumors(IMTs)are exceptionally rare neoplasms with intermediate malignant potential.Surgery is the accepted treatment option,aiming for complete resection with clear margins.CASE SUMMARY A 39-year-old woman presented with a growing solitary pulmonary nodule measuring 2.0 cm in the right upper lobe(RUL)of the lung.The patient underwent a RUL anterior segmentectomy using uniportal video-assisted thoracoscopy.A preliminary tissue diagnosis indicated malignancy;however,it was later revised to an IMTs.Due to the absence of a minor fissure between the right upper and middle lobes,an alternative resection approach was necessary.Therefore,we utilized indocyanine green injection to aid in delineating the intersegmental plane.Following an uneventful recovery,the patient was discharged on the third postoperative day.Thereafter,annual chest tomography scans were scheduled to monitor for potential local recurrence.CONCLUSION This case underscores the challenges in diagnosing and managing IMTs,showing the importance of accurate pathologic assessments and tailored surgical strategies.

文摘BACKGROUND Total knee arthroplasty(TKA)is a mature procedure recommended for correcting knee osteoarthritis deformity,relieving pain,and restoring normal biomechanics.Although TKA is a successful and cost-effective procedure,patient dissatisfaction is as high as 50%.Knee pain after TKA is a significant cause of patient dissatisfaction;the most common location for residual pain is the anterior region.Between 4%and 40%of patients have anterior knee pain(AKP).AIM To investigate the effect of various TKA procedures on postoperative AKP.METHODS We searched PubMed,EMBASE,and Cochrane from January 2000 to September 2022.Randomized controlled trials with one intervention in the experimental group and no corresponding intervention(or other interventions)in the control group were collected.Two researchers independently read the title and abstract of the studies,preliminarily screened the articles,and read the full text in detail according to the selection criteria.Conflicts were resolved by consultation with a third researcher.And relevant data from the included studies were extracted and analyzed using Review Manager 5.4 software.RESULTS There were 25 randomized controlled trials;13 were comparative studies with or without patellar resurfacing.The meta-analysis showed no significant difference between the experimental and control groups(P=0.61).Six studies were comparative studies of circumpatellar denervation vs non-denervation,divided into three subgroups for meta-analysis.The two-subgroup meta-analysis showed no significant difference between the experimental and the control groups(P=0.31,P=0.50).One subgroup meta-analysis showed a significant difference between the experimental and control groups(P=0.001).Two studies compared fixed-bearing TKA and mobile-bearing TKA;the results meta-analysis showed no significant difference between the experimental and control groups(P=0.630).Two studies compared lateral retinacular release vs non-release;the meta-analysis showed a significant difference between the experimental and control groups(P=0.002);two other studies compared other factors.CONCLUSION Patellar resurfacing,mobile-bearing TKA,and fixed-bearing TKA do not reduce the incidence of AKP.Lateral retinacular release can reduce AKP;however,whether circumpatellar denervation can reduce AKP is controversial.
文摘BACKGROUND Over 90%of rectal cancer patients develop low anterior resection syndrome(LARS)after sphincter-preserving resection.The current globally recognized evaluation method has many drawbacks and its subjectivity is too strong,which hinders the research and treatment of LARS.AIM To evaluate the anorectal function after colorectal cancer surgery by quantifying the index of magnetic resonance imaging(MRI)defecography,and pathogenesis of LARS.METHODS We evaluated 34 patients using the standard LARS score,and a new LARS evaluation index was established using the dynamic images of MRI defecography to verify the LARS score.RESULTS In the LARS score model,there were 10(29.41%)mild and 24(70.58%)severe cases of LARS.The comparison of defecation rate between the two groups was 29.36±14.17%versus 46.83±18.62%(P=0.004);and MRI-rectal compliance(MRI-RC)score was 3.63±1.96 versus 7.0±3.21(P=0.001).Severe and mild LARS had significant differences using the two evaluation methods.There was a significant negative correlation between LARS and MRI-RC score(P<0.001),and they had a negative correlation with defecation rate(P=0.028).CONCLUSION MRI defecography and standard LARS score can both be used as an evaluation index to study the pathogenesis of LARS.
文摘Objective:To observe the clinical effect of articular cavity injection combined with bite splint therapy for the treatment of anterior disc displacement without reduction(ADDWoR).Methods:The research subjects for this study were 30 patients with ADDWoR treated in the temporomandibular joint specialist outpatient clinic from November 2018 to November 2019,with a disease duration of 1 to 6 months.The treatment group was treated with an articular cavity injection of sodium hyaluronate+bite splint.The control group was treated with a simple articular cavity injection of sodium hyaluronate.The two groups were followed up once every 2 weeks to evaluate the treatment effect and observe the clinical efficacy of the two groups.Statistical analysis was carried out using SPSS 24.0.t-test and general linear regression analysis were carried out to compare the data of both groups,andχ^(2)-test and binary logistic regression analysis were performed for pain index comparison.Results:There was no significant difference in terms of the efficacy of the treatment received by both groups.The mouth opening and joint pain of patients in both groups were significantly improved after treatment(P<0.001).Conclusion:Articular cavity injection of sodium hyaluronate and occlusal splint therapy are both effective and safe methods for treating ADDWoR.
文摘Objectives: To study the biometric dimensions of upper front teeth in a Hong Kong SAR population including gender differences and compare this with the often recommended use of the Golden Proportion when selecting tooth proportions. Methods: A sample of dental casts was obtained from 100 patients: 50 females and 50 males with an age range from 18 to 35 years. The sample was selected based on the criteria of intact maxillary anterior dental arches, free from imbrications and crowding, no restorations or replaced teeth in the upper front teeth. The width and length of the 600 upper anterior teeth included in the casts were measured, together with the combined upper anterior tooth width for each cast. Analysis of width/height ratio, sexual dimorphism, and golden proportions was statistically analyzed. The data was analysed by SPSS using one-sample t-test, two-sample t-test, and paired t-test. Results: Most measurements had a normal distribution. Paired sample t-test revealed that the average length of male maxillary incisors is significantly higher than female maxillary incisors, while there is no obvious difference in maxillary incisor width. The mean width/length ratio of maxillary incisors ranges from 0.78 to 0.87. The mean values of maxillary apparent tooth width prove that the golden proportion (GP) ratio 1.618 was absent in the current sample. The current study data shows that the mean values of tooth width and length differed from some other populations. Conclusions: Based on the findings of this research, there is no statistically significant difference in the maxillary anterior tooth dimensions for the right and left sides of the arch. Length and width dimensions of the central incisor (CI) were greater than those of lateral incisor (LI) and Canine (C) for both genders, suggesting CI to be the dominant anterior tooth. Some gender differences in tooth dimensions, with males tend to have longer tooth dimensions than females, the average width/length ratio of the female is higher than male, which confirms that the male tends to have longer teeth. The result shows the absence of golden proportion (GP) ratios suggesting that the Golden Proportion guideline was not applicable for the Hong Kong SAR population for either gender.
文摘To provide an anatomical basis for clinical implant esthetics,we evaluated the morphology of the nasopalatine canal(NPC) and analyzed labial and interproximal bone anatomy at the maxillary anterior region.We sought to investigate the effect of maxillary protrusion and tooth labiolingual inclination on labial bone anatomy in Chinese adults.Three dimensional(3D) images were reconstructed using cone-beam computed tomography(CBCT) images from 80 Chinese subjects and by SimPlant 11.04.The dimensions of the NPC,the thickness and profile of the labial bone,the width and height of the interproximal bone,angle sella-nasion-subspinale(SNA) and angle upper central incisor-nasion,subspinale(U1-NA) were measured.The incisive foramen of the NPC was markedly wider than its nasal foramen.The dimension of its labial bone wall demonstrated an increasing width from the crestal to apical measurements.The labial bone at the maxillary anterior region was rather thin,especially at 3 mm below the cemento-enamel junction(CEJ) and the mid-root level;the profile of the labial bone was more curved at the central incisor,and the interproximal bone became wider and shorter posteriorly.There were significant relationships between maxillary protrusion and labial bone profile,tooth labiolingual inclination and labial bone thickness(P < 0.02).To achieve optimal esthetic outcome of implant,bone augmentation is necessary at the maxillary anterior region.For immediate or early placement at the maxillary anterior region,the implant should be located palatally to reduce labial bone resorption and marginal recession;its apex should be angulated palatally to avoid labial perforation at the apical region.To protect the NPC,implants at the central incisor region should be placed away from NPC.

文摘AIM:To investigate whether the two-step strategy[conjunctival flap covering surgery(CFCS)combined with secondary deep anterior lamellar keratoplasty(DALK)]is effective for patients with high-risk fungal keratitis(FK).METHODS:In this noncomparative,retrospective case series,10 subjects(6 males,4 females)with a mean age of 56.5±7.1(range 47-72)y with high-risk FK undergone the two-step strategy were included.Reported outcome measures were healing of the corneal ulcer,recurrence of FK,reject reaction,improvement in best corrected visual acuity(BCVA)and relevant complications.RESULTS:The average diameter of corneal infiltrates was 7.50±0.39 mm,ranging from 6.94 to 8.13 mm.The mean depth of corneal infiltrates was 422.4±77.1μm,ranging from 350 to 535μm.The mean corneal thickness was 597.4±117.3μm,ranging from 458 to 851μm.Hypopyon and endothelial plaques were presented in all patients.The period between the two steps was 3.65±0.9(ranging from 3 to 5)mo.The graft diameter was 7.75±0.39 mm.At the last follow-up(average 9.25±3.39,ranging from 5.5 to 17mo),no fungal recurrence or graft rejection appeared,and all patients showed improvement of BCVA.One patient suffered from liver function impairment due to oral voriconazole for 4wk and recovered spontaneously after 1wk of drug withdrawal.CONCLUSION:The two-step strategy is safe and effective in the treatment of high-risk FK by transforming intentional therapeutic penetrating keratoplasty during acute infection to later optical DALK.It is a practical strategy,especially in areas lacking fresh donor corneas and eye bank services.
文摘BACKGROUND Many studies have focused on the femoral tunnel technique and fixation method,but few studies have involved the tibial tunnel technique and fixation method.The all-inside technique is one of the new techniques that has been described in recent years.All-inside anterior cruciate ligament(ACL)reconstruction is based on a tibial socket instead of a full tunnel.This method has many potential advantages.AIM To compare clinical outcomes of knee ACL autograft reconstruction using allinside quadrupled semitendinosus(AIST)and traditional hamstring tendon(TBT)techniques.METHODS From January 2017 to October 2019,the clinical data of 80 patients with ACL reconstruction were retrospectively analyzed,including 67 males and 13 females.The patients had an average age of 24.3±3.1 years(age range:18-33 years).The AIST technique was used in 42 patients and the TBT technique was used in 38 patients.The time between operation and injury,operative duration,postoperative visual analogue scale(VAS)score and knee functional recovery were recorded and compared between the two groups.The International Knee Documentation Committee(IKDC)and Lysholm scoring system were used to comprehensively evaluate clinical efficacy.RESULTS Eighty patients were followed for 24-36 mo,with an average follow-up duration of 27.5±1.8 mo.There were no significant differences in the time between surgery and injury,operative duration,IKDC and Lysholm scores of the affected knee at the last follow-up evaluation between the two groups.There were significant differences in VAS scores 1 d,3 d,7 d,2 wk and 1 mo after surgery(P<0.05).There was no significant difference in VAS score at 3 mo,6 mo and 1 year after operation.CONCLUSION The efficacy of the AIST ACL reconstruction technique was comparable to the TBT technique,but the postoperative pain was less with the AIST technique.Thus,the AIST technique is an ideal treatment choice for ACL reconstruction.

文摘AIM:To compare anterior segment parameters between two groups of type 2 diabetic with and without diabetic retinopathy(DR)and non-diabetic elderly subjects based on hemoglobin A1c(Hb A1c)levels and status of DR.METHODS:This study was conducted on 997 residents aged 60y or over in Tehran,Iran.Diabetic group had Hb A1c level≥6.4%with no other systemic problems.The non-diabetic participants had normal eye findings and no systemic diseases.K1,K2,mean K,Q-value,anterior,central,posterior,and total corneal densitometric findings,anterior chamber volume(ACV),anterior chamber depth(ACD),corneal volume(CV),and pachymetry were measured by Pentacam AXL.RESULTS:A total of 678 non-diabetic(39%male)and 319 diabetic(35%male)subjects with mean age of 66.31±5.23 and 67.22±4.96y were examined,respectively.No statistically significant difference was found in anterior segment parameters between non-diabetic and diabetic groups(all P>0.05).However,middle,posterior,and total corneal densitometric values were statistically different between two groups af ter controlling the ef fects of confounders(P=0.014,0.007,and 0.042,respectively).Corneal densitometric values in all layers,ACD,and ACV were different between diabetic subjects with and without DR(all P<0.05).In the diabetic group,only corneal densitometric values had a negative relationship with fasting blood sugar(P<0.001).ACD and ACV had a negative correlation with Hb A1c levels(all P<0.05,r=-0.129 and-0.146,respectively).However,the relationships were not observed after controlling the confounders(P=0.938,0.466,respectively).CONCLUSION:Considering the higher densitometric values of the cornea and lower ACD and ACV in diabetic subjects with DR,it is suggested that the examiners should perform comprehensive retinal examinations when faced with such conditions.
文摘Background: Uveitis is a serious disease which dangerous complications can jeopardize the visual prognosis. Anterior uveitis (AU) is the inflammation of the anterior uvea which is composed of the iris and the ciliary body. The objective of the study was to identify the epidemiological and etiological determinants of non-traumatic anterior uveitis at the Campus Teaching Hospital of Lomé. Materials and methods: Retrospective cross-sectional study of the records of patients diagnosed with anterior uveitis (AU) without a notion of trauma in the ophthalmology department of CHU Campus of Lomé from January 1, 2010 to December 31, 2019 (10 years). Results: 141 cases of uveitis, representing a prevalence of 0.18%. Female predominance, with a sex ratio of 0.76. Mean age was 34.74 ± 13.20 years. Decreased visual acuity was the primary complaint (34.40%), followed by ocular pain (28%). Non-traumatic anterior uveitis was unilateral in 87.2% of cases. Retro-corneal precipitates were present in all patients. 61.60% of patients had Tyndall in the anterior chamber. The etiology of non-traumatic AU was undetermined in 76.80% of cases. Toxoplasmosis, tuberculosis and syphilis were the main etiologies found. Conclusion: Non-traumatic anterior uveitis is relatively rare but serious, often affecting young subjects. It is a pathology that engages eye health professionals, not only because of the difficulties involved in diagnosing the etiology, but also because of its progression which sometimes leads to blindness.

文摘Objective:To describe the outcome of female anterior wall(pubic side)onlay urethroplasty with buccal mucosal graft using laterally extended surgical dissection in patients with previously failed minimally invasive techniques.Methods:From January 2016 to April 2018,17 symptomatic patients with previously failed minimally invasive procedures were enrolled in the study.The diagnosis of urethral stricture was confirmed based on a combination of patients’symptoms,post-void residual urine,video-urodynamics,and cystoscopy.Urethroplasty with lower lip mucosal graft was performed using the modified laterally extended dissection.Patients were evaluated pre-operatively and 12-month post-operatively with the American Urological Association symptom score,post-void residual urine,and maximum flow rate.Results:Despite the previously failed minimally invasive procedures,urethroplasty with lower lip buccal graft and laterally extended dissection resulted in favorable outcomes(success rateZ94%).The meanstandard deviation of American urological association symptom score improved from pre-operative levels at the 12-month post-operative follow-up(25.823.97 to 10.885.57);so did postvoid residual urine(71.1274.98 mL to 15.0028.30 mL),and maximum flow rate(7.881.72 mL/s to 25.825.59 mL/s)with all statistically significant(p<0.05).Conclusion:The current study showed that female urethroplasty with buccal graft could be highly successful in experienced hands.An anterior approach could be superior to the posterior one due to higher mechanical support and lower sacculation rate.A laterally extended incision may improve visualization and better graft placement by providing wider working space.The results should be evaluated in the future studies with larger sample size.
文摘Injury to the anterior talofibular ligament(ATFL)is a common acute injury of the lateral foot ligament.Untimely and improper treatment significantly affects the quality of life and rehabilitation progress of patients.The purpose of this paper is to review the anatomy and the current methods of diagnosis and treatment of acute injury to the ATFL.The clinical manifestations of acute injury to the ATFL include pain,swelling,and dysfunction.At present,non-surgical treatment is the first choice for acute injury of the ATFL.The standard treatment strategy involves the“peace and love”principle.After initial treatment in the acute phase,personalized rehabilitation training programs can be followed.These may involve proprioception training,muscle training,and functional exercise to restore limb coordination and muscle strength.Static stretching and other techniques to loosen joints,acupuncture,moxibustion massage,and other traditional medical treatments can relieve pain,restore range of motion,and prevent joint stiffness.If the non-surgical treatment is not ideal or fails,surgical treatment is feasible.Currently,arthroscopic anatomical repair or anatomical reconstruction surgery is commonly used in clinical practice.Although open Broström surgery provides good results,the modified arthroscopic Broström surgery has many advantages,such as less trauma,rapid pain relief,rapid postoperative recovery,and fewer complications,and is more popular with patients.In general,when treating acute injury to the ATFL,treatment management and methods should be timely and reasonably arranged according to the specific injury scenario and attention should be paid to the timely combination of multiple therapies to achieve the best treatment results.
