OBJECTIVE@#To explore the effectiveness of Nice knot technique for wound closure in Gustilo type ⅢA and ⅢB open tibial fractures.@*METHODS@#A retrospective study was performed on 22 patients with Gustilo type ⅢA and ⅢB open tibial fractures, who underwent wound closure using the Nice knot technique and were admitted between June 2021 and June 2022. There were 15 males and 7 females. The age ranged from 18 to 67 years, with an average of 41.9 years. The causes of injury included traffic accident in 11 cases, falling from height in 7 cases, and heavy object injuries in 4 cases. Fractures were located on the left side in 9 cases and on the right side in 13 cases. And 9 cases were type ⅢA fractures and 13 were type ⅢB fractures according to Gustilo classification. All patients had extensive soft tissue injuries, and no vascular or neurological damage was observed. The time from injury to debridement was 3-8 hours (mean, 6.5 hours). The sizes of wounds before operation and at 2 weeks after operation were measured and wound healing rate at 2 weeks after operation were calculated. The wound healing time and wound healing grading were recorded. The Vancouver Scar Scale (VSS) score was used to assess the wound scar after wound healed and the excellent and good rate was calculated.@*RESULTS@#The wound area was 21.0-180.0 cm 2 (mean, 57.82 cm 2) before operation, and it was 1.2-27.0 cm 2 (mean, 6.57 cm 2) at 2 weeks after operation. The wound healing rate at 2 weeks after operation was 76%-98% (mean, 88.6%). After operation, 2 cases needed to adjust Nice knot due to skin cutting and 1 case occurred soft tissue infection on the wound. The other patient's wounds healed. The average wound healing time was 27.8 days (range, 18-44 days). And the wound healing were grade A in 13 cases and grade B in 9 cases. VSS score was 2-9, with an average of 4.1; 10 cases were rated as excellent, 10 as good, and 2 as poor, with an excellent and good rate of 90.9%. All patients were followed up 9-24 months (mean, 14.6 months). During follow-up, no deep infection or osteomyelitis occurred. Two cases experienced fracture non-union, and were treated with compression fixation and bone grafting. The fractures of the other patients all healed, with a healing time of 85-190 days (mean, 148.2 days).@*CONCLUSION@#Nice knot technique can be used in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures effectively, which is easy to operate.

Changes of visual quality and influencing factors after primary angle-closure glaucoma complicated with cataract / 国际眼科杂志(Guoji Yanke Zazhi)

In recent years, the combined surgery of phacoemulsification, intraocular lens implantation, and goniosychialysis has gradually emerged as a primary and effective approach in treating primary angle-closure glaucoma with cataracts. However, with the continuous progress of medical technology, postoperative intraocular pressure control is no longer the sole pursuit. Patients increasingly aspire to achieve higher postoperative visual quality. In order to ensure that patients attain a better refractive status and higher visual quality postoperatively, it is essential to minimize the negative impact caused by primary angle-closure glaucoma. This involves personalized selection of different intraocular lenses or calculation formulas,etc. Evaluation metrics for visual quality encompass visual acuity, contrast sensitivity, higher-order aberrations, subjective perception, etc. Therefore, this paper provides a comprehensive review of postoperative refractive shift, higher-order aberrations, contrast sensitivity and their influencing factors, and the selection of intraocular lenses for patients undergoing combined surgery for primary angle-closure glaucoma with cataracts.

Research progress on the pathogenesis of primary angle-closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

Primary angle-closure glaucoma(PACG)is a common cause of blindness, and angle closure is a fundamental pathologic process in PACG. With the development of ophthalmic equipment, the pathogenesis of PACG has been better understood. In addition to the traditional mechanisms of pupillary block and plateau iris, it has been found that its pathogenesis is not only related to abnormal ocular anatomy, but also more closely related to ocular dynamics, genetic factors, and psychophysiologic stressors. This article summarizes the pathogenesis and risk factors of PACG in conjunction with literature reports, with a view to providing guidance for clinical work and useful theoretical support for early diagnosis and treatment options for glaucoma.

Characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

The Impact of Transcatheter or Surgical Defect Closure on Self-Reported Sleep Quality in Adults with Atrial Septal Defect

ABSTRACT Objective: Sleep quality in those with cardiovascular disease is significantly lower than in the general population. This study aimed to explore the effect of transcatheter or surgical closure of atrial septal defect (ASD) on sleep quality. Methods: One hundred nineteen adult patients with ASD who underwent transcatheter or surgical closure were included in the study. Sleep quality was investigated prospectively just before defect closure and six months after defect closure. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality of these patients. Results: PSQI scores were similar in both groups before the procedure in patients who underwent both transcatheter and surgical closure. The PSQI scores six months after transcatheter closure was significantly improved compared to the PSQI score before transcatheter ASD closure (3.5 ± 2.0 vs. 6.9 ± 3.4, respectively; P<0.001). The PSQI scores six months after surgical ASD closure was significantly improved compared to the PSQI score before surgical closure (4.8 ± 2.1 vs. 7.1 ± 2.0, respectively; P<0.001). Total PSQI scores were also statistically different at six months after transcatheter and surgical closure (3.5 ± 2.0 vs. 4.8 ± 2.1, P=0.014). However, six months after both transcatheter and surgical closure, PSQI scores were significantly decreased in both groups which was more pronounced in patients who underwent transcatheter closure. Conclusion: Transcatheter or surgical closure of the defect may be beneficial in improving the sleep quality of adult patients with ASD. Delayed improvement of sleep quality after surgical closure may be an important advantage for transcatheter closure.

Angle-closure glaucoma associated with vitreous prolapse after neodymium-doped yttrium-aluminum-garnet laser posterior capsulotomy

ABSTRACT Capsulotomy with neodymium-doped yttrium--aluminum-garnet (Nd:YAG) laser is an effective treatment for posterior capsule opacification following cataract surgery. A wide opening of the posterior capsule associated with the ruptured anterior hyaloid can cause anterior chamber vitreous prolapse. Two patients who developed angle-closure glaucoma associated with vitreous prolapse following Nd:YAG laser posterior capsulotomy were successfully treated with antiglaucoma medication and peripheral iridotomies. Patient identification for potential risk factors and a careful postoperative follow-up are essential to avoid these serious complications.

Swept-source optical coherence tomography detects anterior-chamber changes in patients with angle-closure after laser peripheral iridotomy / Tomografia de coerência óptica swept-source detecta alterações na câmara anterior em pacientes com fechamento angular após iridotomia

ABSTRACT Purpose: This study aimed to compare an teriorchamber parameters acquired by a swept-source anteriorsegment optical coherence tomography before and after laser peripheral iridotomy. Methods: This study prospectively evaluated 14 patients with primary-angle closure and six patients with primary-angle closure glaucoma. Gonioscopy and anterior-segment optical coherence tomography using the DRI OCT Triton® were performed before and after laser peripheral iridotomy. Anterior-segment optical coherence tomography parameters were studied using scleral spur as reference: angle opening distance at 250, 500, and 750 µm, trabecular-iris space at 500 µm, trabecular-iris angle, trabecular-iris contact length, and iris curvature. Results: Anterior-segment optical coherence tomography identified 61% of the patients with two or more quadrants closed. Gonioscopy identified more closed angles than anterior-segment optical coherence tomography before laser peripheral iridotomy. In angle parameters, only the angle opening distance of 250 µm at the nasal quadrant was not significantly increased after laser peripheral iridotomy. The iris curvature and trabecular-iris contact length showed a significant reduction induced by the laser procedure. Even in eyes in which gonioscopy did not identify angular widening after laser peripheral iridotomy (n=7), the angle opening distance of 750 µm increased (nasal, 0.15 ± 0.10 mm to 0.27 ± 0.16 mm, p=0.01; temporal, 0.14 ± 0.11 mm to 0.25 ± 0.12 mm, p=0.001) and the iris curvature decreased (nasal, 0.25 ± 0.04 mm vs. 0.11 ± 0.07 mm, p=0.02; temporal, 0.25 ± 0.07 mm vs. 0.14 ± 0.08 mm, p=0.007). Conclusions: Anterior-chamber changes induced by laser peripheral iridotomy could be quantitatively evaluated and documented by DRI OCT Triton®

RESUMO Objetivo: Comparar os parâmetros de câmara anterior obtidos através da tomografia de coerência óptica de segmento anterior antes e após a iridectomia periférica a laser. Métodos: Quatorze pacientes com fechamento angular primário e seis com glaucoma primário de ângulo fechado foram prospectivamente avaliados neste estudo. Gonioscopia e tomografia de coerência óptica de segmento anterior com DRI OCT Triton® foram realizadas antes e após a iridectomia periférica a laser. Os seguintes parâmetros de tomografia de coerência óptica de segmento anterior, baseados na localização do esporão escleral, foram avaliados: ângulo de abertura angular a 250 µm, 500 µm e 750 µm, área do espaço entre a íris e o trabeculado a 500 µm, ângulo entre a íris e o trabeculado, extensão do contato entre a íris e o trabeculado e curvatura da íris. Resultados: A tomografia de coerência óptica de segmento anterior identificou 61% dos indivíduos com dois ou mais quadrantes fechados. A gonioscopia identificou mais quadrantes com ângulo fechado do que tomografia de coerência óptica de segmento anterior antes da iridectomia periférica a laser. Quanto aos parâmetros angulares, apenas ângulo de abertura angular a 250 µm no quadrante nasal não aumentou significativamente após a iridectomia periférica a laser. A curvatura da íris e a extensão do contato entre a íris e o trabeculado apresentaram redução significativa induzida pelo procedimento a laser. Mesmo nos olhos em que a gonioscopia não identificou aumento da amplitude angular após iridectomia periférica a laser (n=7), ângulo de abertura angular a 750 µm aumentou (nasal: 0,15 ± 0,10 mm para 0,27 ± 0,16 mm, p=0,01; temporal: 0,14 ± 0,11 mm para 0,25 ± 0,12 mm, p=0,001), e ICURVE diminuiu (nasal: 0,25 ± 0,04 mm vs. 0,11 ± 0,07 mm, p=0,02; temporal: 0,25 ± 0,07 mm vs. 0,14 ± 0,08 mm, p=0,007). Conclusões: As alterações na câmara anterior induzidas pelo iridectomia periférica a laser puderam ser avaliadas quantitativamente e documentadas pelo DRI OCT Triton®.

Introducción: Se presenta un caso clínico de sistema de presión negativa como tratamiento de ventana torácica derecha, realizado en la clínica de heridas. Se describe el tiempo y proceso de cicatrización, desde la llegada del paciente hasta la cicatrización total. Caso: Hombre de 24 años, postoperado de toracotomía, se le colocó terapia de presión negativa inicial a -75mmHg con intensidad media y modalidad continua; se aplicó esponja blanca para proteger el pulmón expuesto y esponja de plata, con tres cambios cada siete días. Posteriormente, se realizaron diez cambios de esponjas cada cuatro días, identificando disminución de las dimensiones de la ventana torácica. En la semana once inició tratamiento con terapia húmeda y fibrina rica en plaquetas, la cual se colocó en el lecho de la herida, aplicándose una vez por semana durante un mes. A partir de la semana quince se realizó curación diaria con aplicación de sulfadiazina de plata. El paciente fue dado de alta en la semana veinte con la herida 100% epitelizada. Conclusiones: El uso de la terapia de presión negativa acelera el proceso de curación, reduce las complicaciones y la carga bacteriana del tejido, debido a que la esponja de plata actúa como barrera antimicrobiana.

Introduction: A clinical case of negative pressure system as a right thoracic window treatment, performed in the wound clinic, is presented. The time and healing process from patient arrival to complete healing is described. Case: A 24-year-old man, postoperative thoracotomy, was placed on negative pressure therapy at -75mmHg with medium intensity and continuous mode; white sponge was applied to protect the exposed lung and silver sponge, with three changes every seven days. Subsequently, ten sponge changes were performed every four days, identifying a decrease in the dimensions of the thoracic window. In week eleven, the patient started treatment with wet therapy and platelet-rich fibrin, which was placed in the wound bed and applied once a week for a month. From week fifteen onwards, daily healing was performed with silver sulfadiazine application. The patient was discharged at week twenty with the wound 100% epithelialized. Conclusions: The use of negative pressure therapy accelerates the healing process, reduces complications and tissue bacterial load, due to the silver sponge acting as an antimicrobial barrier.

Glauco-Claw: A novice implant for chronic angle-closure glaucoma

This article describes 1-year outcomes of a new intra-ocular implant, “Glauco-Claw,” in refractory chronic angle-closure glaucoma (ACG). Glauco-Claw is a novice polymethylmethacrylate implant with a central ring and five claws placed circumferentially. It was placed in the anterior chamber and the peripheral iris was tucked into the claws, thus causing goniosynechialysis and preventing the reformation of goniosynechiae. It was implanted in five eyes of five patients, and they were followed up for 1 year. Target intra-ocular pressure was achieved and maintained in all the patients till the last follow-up. Two patients did not require any anti-glaucoma medication. No significant complications were observed in any patient. Glauco-Claw could be another armamentarium in the management of refractory chronic ACG.

Impact of glaucoma on vision-specific quality of life in monocular glaucoma patients using the Indian vision function questionnaire

Purpose: To evaluate the determinants affecting the quality of life in monocular glaucoma patients using the Indian vision function questionnaire. Methods: In this prospective cross?sectional study, total of 196 patients were divided into two groups: cases and controls. Indian Vision Function Questionnaire (IND?VFQ) was administered and analyzed. One hundred twenty?nine (58.6%) patients who had lost their vision in one eye due to glaucoma were included as cases and 67 (30.4%) patients who had lost their vision due to other causes were taken as controls. Results: Median composite score of subscales was 54.62 (29.7–74.7) in group 1 and 45.38 (23.7–76.7) in group 2. The psychosocial impact scale was the most affected scale, the median scores were 33.02 (0 to 60.0) and 19.07 (0 to 53.0) in groups 1 and 2, respectively. Among all dimensions of IND?VFQ, the highest score was for color vision 100.0 (0–100.0) and 100.0 (0–100.0), and the lowest median score was found in mental health and dependency in both the groups. Multiple linear regression analysis demonstrated that visual acuity was associated with a low score (P < 0.001). Female gender was significantly associated with the overall score in the univariate model (P = 0.006). Conclusion: Monocular glaucoma patients have a poor general and vision?related quality of life. Depression associated with monocularity and the perception of dependency and being a burden on their family members greatly impacted the mental health of the participants

Purpose: This video is compilation of short video clips and images which gives description on identification of angle closure due to pupillary block, peripheral anterior synechiae, iris bombe, plateau iris, supra ciliary effusion, and malignant glaucoma. It also shows video demonstrating partially and fully patent iridotomy and features of trabeculectomy bleb. Synopsis: This video summarizes importance of UBM application in angle closure glaucoma to understand its pathophysiology by showing the relationship between the peripheral iris, trabecular meshwork and ciliary processes. Highlights: UBM provides two?dimensional, grayscale images of the angle structures and allows identification of non?pupillary block mechanism in angle closure glaucoma, which can be recorded for qualitative and quantitative analyses.

Atrial Septal Defect Occluder Device Embolization: Experience of a Tertiary Care Cardiac Center

Background: Percutaneous device closure of atrial septal defect (ASD) has become an increasingly popular procedure as it offers several advantages. However, it is associated with infrequent, but life?threatening complications such as device embolization. Objective: To analyze the risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed. Settings and Design: A retrospective study was performed at a tertiary referral center for cardiac services. Material and Methods: Pre?procedure, intra?procedure, and post?procedure data of patients whose ASD device embolized was collected retrospectively and analyzed for risk factors, common sites of embolization, associated complications, timing of embolization, and the treatment executed. Results: Thirty devices were embolized, out of which 13 were retrieved percutaneously in the Catheter laboratory, whereas 17 patients underwent surgery. Fourteen patients had an unfavorable septal morphology for device closure. Ten devices were embolized in the catheter laboratory, five in the intensive care unit, and two in the ward. The devices were embolized to almost all chambers of the heart and great vessels. One patient had an inferior vena cava rim tear while attempting percutaneous retrieval. One patient required a short period of total circulatory arrest (TCA) for retrieval of the device from ascending aorta, while another required a lateral position for retrieval from descending aorta. One patient required re?exploration for bleeding, while another had an air embolism and succumbed. Conclusions: Once embolization occurs, the risks associated increase manifold. Most of the surgical extractions are uneventful; however, there could be certain complications that may need repair of valvular apparatus, the institution of TCA, or the need for the lateral position. Air embolization though very rare can occur which could be fatal.

A Master Mind Game Code Algorithm Approach to Help Surgical Decision-Making between Retropharyngeal Fat Grafting and Pharyngoplasty for the Treatment of Velopharyngeal Incompetence

Abstract Introduction Velopharyngeal insufficiency (VPI) is a controversial pathology with many surgical options. Objectives To compare pharyngoplasty and retropharyngeal fat grafting and to build a prognostic tool to achieve perfect speech. Methods Retrospective observational cohort study of 114 patients operated for VPI from 1982 to 2019 in a single tertiary center. The instrumental assessment was made using an aerophonoscope and nasofibroscopy. The variables sex, age, genetic syndromes, and type of diagnosis were analyzed with logistic regression model adjusted with propensity score. To generalize results and to build a surgical predictive tool, a marginal analysis concludes the study. Results Among the patients (median [range] age 7 [4-48]), 63 (55.26%) underwent pharyngoplasty and 51 (44.74%) graft. The graft group had no complication, but it had a failure rate of 7.84%. The pharyngoplasty group had no failure, but one patient had postoperative obstructive sleep apnea. The marginal analysis demonstrated that age lower than 7 years, cleft lip and palate, absence of syndrome, and intermittent VPI were important predictive factors of good result regardless of surgical technique. Conclusions Without a statistical demonstration of the superiority of pharyngoplasty over graft, and in the uncertainty of literature background, our perfect-speech patient profile represents an important tool for a postoperative forecast of results in which, like in the Master Mind game, every feature has to be considered not individually but as a pattern of characteristics whose association contributes to the outcome.

Imaging iridotrabecular contact in angle closure

Background: With ultrasound biomicroscopy (UBM), radial scans are taken by using a typical ciliary process, to show the details of the iridocorneal angle, the anterior surface of the ciliary body, and its relation to the posterior iris. Appositional closure represents potentially reversible contact between the peripheral iris and trabecular meshwork. The appositional closure can further be classified according to the configuration of iridotrabecular contact (ITC). UBM can be performed in dark and light conditions, which has been shown to be useful for detecting changes in iridocorneal angle configuration associated with dark and light. Purpose: To image ITC configuration in appositional angle closure and also image iridocorneal angle in dark and bright light room illumination. Synopsis: UBM demonstrates two types of ITC configuration in appositional closure which are, B?type and S?type. It can also demonstrate the presence of sinus of Mapstone in S?type of ITC. Highlights: UBM allows imaging of dynamic changes in the iris and shows that the degree of appositional angle closure is a dynamic process that can change rapidly depending on the lighting conditions.

Relatively anterior lens position in primary angle-closure glaucoma eyes with long axial length

Purpose: To evaluate the refractive status and ocular biometric parameters in primary angle?closure glaucoma (PACG) eyes with different axial lengths (ALs). Methods: In total, 742 Chinese PACG subjects with complete ophthalmic examinations were enrolled. The refractive status was categorized as myopia (spherical equivalent [SE] ??0.5 D), emmetropia (?0.5 D < SE < +0.5 D), and hyperopia (SE ?+0.5 D), whereas the AL was divided into short (AL <22.5 mm), regular (22.5 ? AL <23.5 mm), and long (AL ?23.5 mm). The refractive status and ocular biometric parameters were compared among different AL groups. Results: The mean AL of the PACG eyes was 22.53 ± 0.84 mm (range: 19.68–25.57 mm). The refractive status was significantly different among different AL groups (P < 0.001). Also, 92.6% of hyperopic PACG eyes showed AL <23.5 mm, and 19.0% of myopic PACG eyes showed AL ?23.5 mm. The SE showed significant differences among different AL groups only in the hyperopic subjects (P = 0.012). The AL was significantly longer in myopic eyes (P < 0.001). The PACG eyes with longer AL exhibited lower keratometry, longer central anterior chamber depth and corneal diameter, and lens position and relative lens position closer to the anterior (P < 0.001). Conclusion: Axial hyperopia was common in PACG eyes, and axial myopia was not uncommon. Relatively anterior lens position could explain the occurrence of PACG in the eyes with long AL.

Glaucoma suspects referred by general ophthalmologists to a tertiary center in Brazil: outcomes of the glaucoma specialist assessment / Suspeitos de glaucoma encaminhados do oftalmologista geral para um centro terciário no Brasil: resultados da avaliação do especialista em glaucoma

ABSTRACT Purpose: To characterize patients with suspected glaucoma who were referred to the clinic for suspected glaucoma in a tertiary public hospital in southern Brazil and to evaluate differences in functional and structural damages between patients diagnosed with different types of glaucoma, those with normal eye examination results, and those who remained as glaucoma suspects. Methods: This is a cohort study of patients referred by general ophthalmologists to the clinic for suspected glaucoma at Hospital Nossa Senhora da Conceição, Porto Alegre, Brazil, between March 2016 and December 2018. The patients were followed up until they had undergone reliable examinations (eye examination, visual field screening, and optic coherence tomography for classification as normal and having a suspected glaucoma, glaucoma with an elevated intraocular pressure, normotensive glaucoma, or ocular hypertension. Results: A total of 135 patients were included in this study. Of the patients, 117 subjects completed all examinations and met the inclusion criteria. Most patients were normal (36.8%), followed by those with suspected glaucoma (25.64%), normal tension glaucoma (18.8%), glaucoma with elevated intraocular pressure (12%), and ocular hypertensive (6%). The main reason for referral was increased optic nerve head cupping. The patients with normal tension glaucoma were older than the other subjects on average (p=0.03). In addition, the normal tension glaucoma group had a significantly worse baseline visual field index and mean deviation of the visual field than the normal, glaucoma suspect, and ocular hypertensive groups. The circumpapillary retinal nerve fiber layer on OCT was thinner on average in the normal tension glaucoma group than in the normal and glaucoma suspect groups (p<0.002) but did not significantly differ between the glaucoma group with elevated intraocular pressure and the other groups. Conclusions: Patients with normal tension glaucoma tend to be diagnosed later because of their normal intraocular pressures; thus, the optic nerve cupping must be greater to raise the suspicion of glaucoma. In this study, we found that the patients with normal tension glaucoma had worse disease at the time of diagnosis.

RESUMO Objetivo: Caracterizar a população com suspeita de glaucoma encaminhada a um centro público terciário no sul do Brasil e avaliar diferenças no dano dos parâmetros funcionais e estruturais entre os pacientes diagnosticados com diferentes tipos de glaucoma e aqueles classificados como normais e aqueles mantidos como suspeitos de glaucoma. Métodos: Esta é uma coorte dos pacientes encaminhados para o setor de glaucoma suspeito do Hospital Nossa Senhora da Conceição, Porto Alegre - BR, no período de março de 2016 a dezembro de 2018. Os pacientes foram acompanhados até obterem exames confiáveis (exame oftalmológico completo, campimetria visual, tomografia de coerência óptica) para serem classificados como: normal, glaucoma suspeito, glaucoma com pressão intraocular elevada, glaucoma de pressão normal ou hipertenso ocular. Resultados: Um total de 135 pacientes foram incluídos neste estudo, sendo que destes, 117 pacientes completaram todos os exames e foram incluídos neste estudo. A maioria dos pacientes foi considerada normal (36,8%), seguido por glaucoma suspeito (25,64%), glaucoma de pressão normal (18,8%), glaucoma com pressão intraocular elevada (12%) e hipertensão ocular (6%). A principal razão para encaminhamento foi escavação do nervo óptico aumentada. Pacientes com glaucoma de pressão normal eram em média mais velhos que os demais (p=0,03). Esses também apresentavam índice de campo visual e desvio médio da campimetria visual piores que sujeitos normal, com suspeita de glaucoma e hipertensos oculares, e tinham a camada de fibra nervosa medida pela tomografia de coerência óptica mais fina que normais e suspeitos de glaucoma (p<0,002). Os pacientes com glaucoma de pressão elevada não diferiram significativamente dos outros grupos. Conclusão: Pacientes com glaucoma de pressão normal tendem a ser diagnosticados mais tardiamente devido ao fato da pressão intraocular não estar elevada, logo a escavação do disco óptico deve ser maior para gerar a suspeita de glaucoma. Neste estudo, paciente com glaucoma de pressão normal apresentaram doença mais avançada no momento do diagnóstico em comparação com os outros grupos.

Cierre dinámico y toxina botulínica: una alternativa novedosa para el cierre definitivo del abdomen abierto y contenido / Dynamic closure system and botulinum toxin: a novel alternative for definitive closure of open abdomen

RESUMEN Se presenta el caso de un paciente masculino de 54 años que, cursando internación por neumonía- COVID-19, intercurrió con shock séptico por diverticulitis aguda Hinchey IV, por lo que se realizó cirugía de Hartmann. Evolucionó con isquemia colónica, se realizó colectomía total y abdomen abierto y contenido (AAyC). El manejo del AAyC se realizó con sistema de vacío (VAC) durante 7 semanas, resultando un AAyC tipo IIIa (Björck) con un gap de 16 cm. Se decidió iniciar, una vez dadas las condiciones clínicas del paciente, el cierre dinámico (CD) con tracción fascial con malla de polipropileno asociado a inyección de toxina botulínica (TB). Esta estrategia permitió el cierre fascial primario (CFP) de la pared abdominal en la quinta semana de comenzado el tratamiento, evitando de esta manera la morbilidad de un cierre por segunda intención.

ABSTRACT We report the case of a 54-year-old male patient hospitalized for COVID-19 pneumonia who developed septic shock due to acute Hinchey IV diverticulitis and required Hartmann's surgery. The patient evolved with colonic ischemia and underwent total colectomy and open abdomen (OA) with temporary abdominal closure (TAC) that was managed with a vacuum-assisted wound closure (VAWC) system for 7 weeks, resulting in a Björck grade 3A OA with a 16-cm gap. As he had a favorable clinic course, dynamic closure with mesh-mediated fascial traction was decided, associated with botulinum toxin (BT) injection. This strategy allowed primary fascial closure (PFC) of the abdominal wall 5 weeks after treatment was initiated, thus avoiding the complications of healing by secondary intention.
