The effects of drainage tube on pain and functional recovery after unicompartmental knee arthroplasty / Efeitos do tubo de drenagem na dor e recuperação funcional após artroplastia unicompartimental do joelho

ABSTRACT Objective: The objective of this study was to evaluate the impact of drainage tube placement on postoperative pain, recovery, and opioid consumption within a 72-hour period following unicompartmental knee arthroplasty (UKA). Methods: Patients with medial knee osteoarthritis who underwent UKA from January 2019 to August 2020 were enrolled in the study and divided into two groups based on whether they received a drain postoperatively. Results: The drainage group had significantly lower VAS scores on day 1, day 2, and day 3, in addition to significantly smaller changes in the circumference of the knee joint within 3 days postoperatively (P <0.05). The ROM in the drainage group significantly increased at 3 days and 1 month post-surgery, with a statistically significant difference in morphine consumption between the two groups at 3 days (P<0.05). The incidence of postoperative nausea and vomiting (5 cases) and wound bleeding (1 case) was lower in the drainage group compared to the non-drainage group (P<0.05). Conclusions: The placement of a drainage tube in UKA may reduce the swelling of knee joint and pain, which not only reduces the use of Opioid but also facilitates early functional activities of the knee joint. Level of Evidence III; Retrospective Comparative Study.

RESUMO Objetivo: O objetivo deste estudo foi avaliar o impacto da implantação do tubo de drenagem na dor pós-operatória, na recuperação e no consumo de opioides em um período de 72 horas após a artroplastia unicompartimental do joelho (UKA). Métodos: Pacientes com osteoartrite medial do joelho submetidos à UKA de janeiro de 2019 a agosto de 2020 foram incluídos no estudo e divididos em dois grupos com base no fato de terem ou não recebido um dreno no pós-operatório. Resultados: O grupo de drenagem apresentou escores EVA significativamente menores no dia 1, no dia 2 e no dia 3, além de alterações significativamente menores na circunferência da articulação do joelho em 3 dias de pós-operatório (P <0,05). A ADM no grupo de drenagem aumentou significativamente em 3 dias e 1 mês após a cirurgia, com uma diferença estatisticamente significativa no consumo de morfina entre os dois grupos em 3 dias (P<0,05). A incidência de náuseas e vômitos no pós-operatório(5 casos) e sangramento da ferida (1 caso) foi menor no grupo de drenagem em comparação com o grupo sem drenagem (P<0,05). Conclusão: A utilização de tubo de drenagem na UKA pode reduzir o edema articular do joelho e a dor, reduzindo o uso de opioides e facilitando as atividades funcionais iniciais da articulação do joelho. Nível de Evidência III; Estudo Comparativo Retrospectivo.

Evaluation of early ocular discomfort after glaucoma surgery: trabeculectomy versus Ahmed glaucoma valve implantation

ABSTRACT Purpose: This study aims to compare the initial ocular discomfort symptoms resulting from trabeculectomy and Ahmed glaucoma valve implantation surgeries. Methods: A prospective comparative study was conducted. The evaluation of ocular discomfort employed a questionnaire designed to identify the frequency and severity of distinct symptoms: ocular pain, general discomfort, tearing, foreign body sensation, and burning. This questionnaire was administered prior to surgery as a baseline, and subsequently at 7, 30, and 90 days post-surgery. Simultaneously, the Ocular Surface Disease Index (OSDI) was applied at these same time intervals. Results: The study encompassed a total of 17 patients (9 undergoing trabeculectomy and 8 undergoing Ahmed glaucoma valve implantation). The Ahmed glaucoma valve implantation group exhibited higher tearing levels at baseline (p=0.038). However, no statistically significant differences in symptoms were observed between the two surgeries at 7 and 30 days post-surgery. At the 90-day mark following surgery, patients who had undergone trabeculectomy reported a significantly higher foreign body sensation (p=0.004). Although OSDI scores did not differ between groups at baseline, the trabeculectomy group showed significantly higher OSDI scores than the Ahmed glaucoma valve implantation group at 7, 30, and 90 days after surgery (p<0.05). Conclusion: Post-surgery, patients who had undergone trabeculectomy experienced increased foreign body sensation. Trabeculectomy appears to cause greater early postoperative ocular discomfort compared to the Ahmed glaucoma valve implantation group.

Pars plana vitrectomy combined with pan-retinal photocoagulation, Ahmed glaucoma valve implantation, and/or phacoemulsification for complicated neovascular glaucoma treatment / Vitrectomia pars plana combinada com fotocoagulação panretiniana, implantação da válvula Ahmed para glaucoma e/ou facoemulsificação para tratamento de glaucoma neovascular complicado

ABSTRACT Purpose: To present long-term results of pars plana vitrectomy combined with pan-retinal endolaser photocoagulation, Ahmed glaucoma valve implantation, and/or phacoemulsification in patients with complicated neovascular glaucoma. Methods: The study comprised 15 eyes from 15 patients with neovascular glaucoma as a complication of diabetic retinopathy and owing to ischemic central retinal vein occlusion. There was a vitreous hemorrhage n all of the patients. Furthermore, 8 of the cases showed varying degrees of hyphema. All subjects received an intravitreal injection of bevacizumab three days before surgery. In 12 phakic patients, phacoemulsification, pars plana vitrectomy, and Ahmed glaucoma valve implantation were performed. Pars plana vitrectomy and Ahmed glaucoma valve implantation were performed in 3 pseudophakic patients. Perioperative and postoperative complications, intraocular pressure values, and best-corrected visual acuity scores were also recorded. Results: The mean follow-up was 24.4 ± 14.56 months. The mean preoperative intraocular pressure was 50.06 ± 7.6 mmHg. At 1 day, 7 days, and 1-, 3-, 6-, 12-month, and last visit following surgery, the mean intraocular pressure was 11.06 ± 8.22, 12.66 ± 7.27, 13.8 ± 7.73, 18.64 ± 7.05, 19.28 ± 4.61, 16.28 ± 1.68, and 16.92 ± 2.12 mmHg, respectively (p=0.001 for every follow-up visit). The mean visual acuity on the most recent appointment was 1.18 ± 0.42 logMar (p=0.001 for each subsequent visit). As postoperative early complications, varying degrees of hyphema and fibrin reactions were recorded. During follow-up, one patient developed phthisis bulbi. In 4 cases, Ahmed glaucoma valve revision surgery was required. Conclusions: In patients with complicated neovascular glaucoma, combined surgical procedures are safe, effective, and preferable both in terms of controlling high intraocular pressure and providing reasonable visual abilities.

Todos os casos tiveram hemorragia vítrea. Além disso, 8 dos casos apresentaram diferentes graus de hifema. A injeção intravítrea de bevacizumabe foi administrada em todos os casos 3 dias antes da cirurgia. Facoemulsificação, vitrectomia pars plana e implantação da válvula Ahmed para glaucoma foram realizadas em 12 pacientes fáquicos. A vitrectomia pars plana e a implantação da válvula Ahmed para glaucoma foram realizadas em 3 pacientes pseudofáquicos. Complicações perioperatórias e pós-operatórias, valores de pressão intraocular e valores de melhor acuidade visual corrigida pré-operatório e pós-operatório foram registrados. Resultados: O acompanhamento médio foi de 24,4 ± 14,56 meses. A média da pressão intraocular pré-operatória foi de 50,06 ± 7,6 mmHg. Em 1 dia, 7 dias e 1,3,6,12 meses, e última visita após cirurgia, a média da pressão intraocular foi de 11,06 ± 8,22, 12,66 ± 7,27, 13,8 ± 7,73, 18,64 ± 7,05, 19,28 ± 4,61, 16,28 ± 1,68 e 16,92 ± 2,12 mmHg, respectivamente (p=0,001 para cada visita de acompanhamento). A média da acuidade visual na última visita foi de 1,18 ± 0,42 logMar (p=0,001 para cada visita de acompanhamento). Vários graus de reações de hifema e fibrina foram registrados como complicações precoces pós-operatórias. Phthisis bulbi foi desenvolvido em um caso durante o acompanhamento. A cirurgia de revisão da válvula Ahmed para glaucoma foi necessária em 4 casos. Conclusões: Os procedimentos cirúrgicos combinados que realizamos são seguros, eficazes e preferenciais, tanto em termos de controle da alta pressão intraocular quanto fornecimento de habilidades visuais razoáveis em pacientes com glaucoma neovascular complicado.

Mechanism of HMGB1 in scarring after glaucoma drainage valve implantation / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the dynamic expression of high mobility group box 1(HMGB1)in scar tissues after glaucoma drainage valve implantation, and to further reveal the role and possible mechanism of HMGB1 in scarring after glaucoma surgery.METHODS: A total of 60 New Zealand white rabbits were randomly divided into control group(n=20), model group(n=20, silicone implantation under conjunctival sac)and model with drug administration group(n=20, silicone implantation under conjunctival sac combined with 5-fluorouracil injection). The conjunctival tissues were collected at 4 and 8 wk after surgery. HE staining and Masson staining were used to detect the proliferation and distribution of fibroblasts and collagen fibers in conjunctival tissues. Immunohistochemistry was utilized to detect the distribution and changes of HMGB1, transforming growth factor(TGF)-β1, Smad3 and α-smooth muscle actin(SMA)in conjunctival tissues. RT-PCR and Western blot were adopted to detect the mRNA and protein expression of HMGB1, TGF-β1, Smad3 and α-SMA in conjunctival tissues.RESULTS: HE staining and Masson staining showed that the proliferation of inflammatory cells, fibroblasts and collagen fibers in the model group was significantly higher than that in the control group at both 4 and 8 wk. Meanwhile, the proliferation of fibroblasts and collagen fibers in the model with drug administration group was significantly lower than that in the model group. Immunohistochemical staining showed that the expression of HMGB1, TGF-β1, Smad3 and α-SMA protein was observed in the conjunctival tissues of the model group both 4 and 8 wk, with brown and significantly deeper staining of the model group at 8 wk. Meanwhile, the positive staining in the model with drug administration group at both 4 and 8 wk was significantly lower than that in the model group. There was positive correlations between the number of fibroblasts stained with HE and the expression of HMGB1 in the conjunctival tissue of the model group at both 4 and 8 wk(r=0.602, 0.703, all P&#x0026;#x003C;0.05). RT-PCR and Western blot revealed that the mRNA and protein expression levels of HMGB1, TGF-β1, Smad3 and α-SMA in the model group were significantly higher than those in the control group at both 4 and 8 wk(all P&#x0026;#x003C;0.05). Meanwhile, the mRNA and protein expression levels of HMGB1, TGF-β1, Smad3 and α-SMA in the model with drug administration group were significantly lower than those in the model group(all P&#x0026;#x003C;0.05). There was positive correlations between mRNA expressions of HMGB1 and TGF-β1, Smad3 in the model group and the model with drug administration group(all P&#x0026;#x003C;0.05).CONCLUSION: The expression of HMGB1 increased at a time-dependent manner after glaucoma valve implantation. HMGB1 acts an indispensable role in the initiation and progression of scar formation after glaucoma surgery, which may be involved in the regulation of TGF-β/Smad signaling pathway.

Nonsuperotemporal quadrant implantation of the Ahmed glaucoma valve using modified long scleral tunnel technique for intraocular pressure control

ABSTRACT Purpose: As superotemporal implantation of the Ahmed glaucoma valve is not always feasible in cases of refractory glaucoma, this study examined the characteristics and surgical outcomes of cases in which the valve was implanted in a nonsuperotemporal quadrant using a modified long scleral tunnel technique. Methods: This retrospective case-control study included 37 eyes with nonsuperotemporal quadrant--Ahmed glaucoma valve implantation in Group 1 and 69 eyes with superotemporal Ahmed glaucoma valve implantation in Group 2. The demographic characteristics of these groups, surgical outcomes, including complications, further surgical interventions, and surgical success rates were compared. Surgical success was defined as an intraocular pressure not exceeding 21 mmHg, accompanied by a minimum reduction of 20% in intraocular pressure from the baseline without any additional intraocular pressure-lowering procedures, and the absence of light perception loss or phthisis bulbi. Results: Group 1 had significantly higher numbers of eyes with secondary glaucoma and preoperative surgical procedures than Group 2 (p<0.05). Both groups had mean preoperative intraocular pressure values, and mean intraocular pressure values at the last visit of 34.2 and 27.9 months, 35.5 ± 1.5 and 35.8 ± 1.2 mmHg, and 14.5 ± 5 and 14.9 mmHg, respectively. Although both groups had 70.2% and 75.8% as their five-year cumulative probability of success, respectively, the rates of complications, revisional surgery, and additional surgical procedures did not differ significantly (p>0.05). Conclusion: The modified long scleral tunnel technique for Ahmed glaucoma valve implantation in nonsuperotemporal quadrants achieves intraocular pressure control and complication rates comparable to superotemporal implantation.

En este tejido se pueden desarrollar las mismas patologías que en la mama normal. El manejo curativo es la resección quirúrgica. El objetivo de este estudio fue comparar los resultados de la técnica de resección vía abierta de tejido mamario accesorio con dren vs sin dren. Métodos. Se realizó un estudio observacional tipo cohorte retrospectivo, teniendo en cuenta dos grupos de pacientes con tejido mamario accesorio: a uno de ellos se les realizó resección quirúrgica mediante técnica abierta con dren y al otro grupo sin dren. Además, se incluyó un brazo prospectivo donde se evaluó la calidad de vida y la satisfacción de las pacientes con el resultado posoperatorio mediante el uso de la herramienta Breast-Q. Resultados. Se recolectó la información de 82 pacientes, la mayoría mujeres; 22 se intervinieron con técnica con dren y 60 con técnica sin dren. 13,6 % de los pacientes presentaron complicaciones tempranas, siendo la infección de sitio operatorio la más frecuente (36,4 %). En general, las complicaciones fueron más comunes en el grupo con dren (40,9 % vs 3,4 %), con una diferencia estadísticamente significativa (p=0,000). La calidad de vida fue similar en ambos grupos. Conclusiones. Los pacientes a quienes se les realizó resección de mama supernumeraria y se dejó un sistema de drenaje en el lecho de disección presentaron más complicaciones posoperatorias que las pacientes a quienes no se les dejó dren

Introduction. Accessory breast tissue is a congenital anomaly that occurs in 2-6% of the female population. It can develop the same pathologies that in the normal breast. The curative management of this pathology is surgical resection. The objective of this study was to compare the results of the accessory breast tissue open resection technique with a drain vs without a drain. Methods. An observational retrospective cohort study was conducted considering two groups of patients with accessory breast tissue: one of them underwent surgical resection using an open technique with a drain and the other group without a drain. In addition, a prospective arm where the quality of life and satisfaction of the patients with the postoperative result was evaluated by the Breast-Q tool. Results. Eighty-two patients were included, most of them women; 22 were operated with open technique with drain and 60 without drain. 13.6% of patients presented early complications, with surgical site infection being the most frequent (36.4%) and, in general, complications were more common in the group with drain (40.9% vs 3.4%) with a statistically significant difference (p=0.000). Quality of life was similar in both groups.Conclusions. Patients who undergo supernumerary breast resection and leaving drainage in the dissection bed present more postoperative complications compared to those without drain

Normal Serum Levels of Otolin-1 in Patients with Meniere Disease in Remission

Abstract Introduction Degenerative changes in the otolithic organs have been theorized to be caused by the mechanical obstruction to endolymphatic flow, possibly resulting in endolymphatic hydrops (ELH). Otolin-1 is an otoconial matrix protein that crosses the blood labyrinth barrier and has been found in the serum of healthy and diseased patients. Objective To measure the serum levels of Otolin-1 in Meniere disease (MD) patients and compared them with the healthy individuals. Methods This pilot, cross-sectional study was performed at our tertiary care referral center to compare the serum Otolin-1 levels of healthy individuals with those of MD patients. The blood samples were obtained during patients' visit to the vertigo clinic following remission of an acute episode. The data was analyzed using the Stata/SE version 12.0 (StataCorp. College Station, TX, USA). Comparison between the serum Otolin-1 levels in the two groups was performed using the unpaired t-test. A p-value of 0.05 was considered to be statistically significant. Results The participants were divided into two groups, with 31 MD patients, and 30 age and gender-matched members of the control group. The serum levels of Otolin-1 in MD patients (247.6, ± 44.2 pg/ml) were not found to be significantly different from those of the control group (236.2, ± 43.5 pg/ml) (p = 0.31). Conclusion The current study reveals that the serum levels of Otolin-1 are not significantly different between the patients with MD in the interictal phase and the control group's healthy ones.

Inpatient Decongestive Therapy for Lymphedema in Acute Postsurgical Head and Neck Cancer Patients

Abstract Introduction Head and neck lymphedema is an omnipresent morbidity related to head and neck cancer therapies. Studies on therapy for these patients in the acute postsurgical population have not been published to date. Objective To assess changes in the measurements of lymphedema in surgical head and neck cancer patients during the hospital stay with implementation of modified decongestive therapy (MDT). Methods Patients aged > 18 years undergoing neck dissection with or without primary-site resection or laryngectomy between 2016 and 2019 were included. Facial measurements were obtained prior to beginning MDT and again prior to discharge. A total facial composite measurement was calculated and used to assess change over time. Rates ≥ 2% of change were considered significant. Results A total of 38 patients were included (subsites: larynx = 27; thyroid =4; oral cavity = 3; and neck = 4). The mean number of days between surgery and the start of lymphedema therapy was 3.0 days. The mean number of days between measurements was 5.2 days. Reduction in the total composite score was observed in 37 (97%) patients, and 35 (92%) patients had a total composite reduction score > 2%. Tumor subsite and surgery type did not portend toward greater percent change, except for those patients treated with total laryngectomy, regional flap reconstruction, and neck dissection (p = 0.02). Conclusion Acute postsurgical inpatient MDT was associated with reduced total composite measurements in patients after head and neck surgery. As the first published study on lymphedema therapy in this acute postsurgical period, further prospective case-control studies are warranted to explore further benefits of acute therapy.

Aurolab aqueous drainage implant implantation made easy: A video-based step-by-step guide

Background: Glaucoma is one of the major causes of irreversible blindness in the world, with trabeculectomy still being the primary surgical modality for the management of glaucoma. Glaucoma drainage devices (GDDs) have been conventionally used for the treatment of refractory glaucoma and are found to be beneficial in eyes with prior unsuccessful filtration surgeries and primary choice of surgery in certain glaucoma. Aurolab aqueous drainage implant (AADI) is a nonvalved device useful in refractory glaucoma to achieve low intraocular pressure (IOP). The device has been commercially available in India since 2013 and is like the Baerveldt glaucoma implant in design and function. AADI being the most economical and effective GDD in controlling IOP is becoming a popular choice among ophthalmologist in developing countries. AADI surgery has steep learning curve due to large end?plate surface area which needs a rigorous conjunctival dissection, muscle hooking, meticulous plate fixations, and careful tube ligations and insertion. There are different techniques of performing AADI surgery, but the authors have tried to simplify the complex surgery for easy and catchable learning of the procedure by novice surgeon with their experience and have elaborated a step?wise most effective way of performing surgery. Purpose: This video?based skill transfer depicts steps of AADI surgery with compilation of various modifications and authors’ tips and tricks to novice surgeons. Synopsis: This video depicts detailed steps of AADI surgery with micro?points and authors experience. Video also shows various tailor?made modifications of surgical techniques for different case scenarios. Highlights: Steps of AADI surgery, modifications, and surgical pearls.

Viscotrabeculotomy with anterior chamber irrigation versus Ahmed glaucoma valve implantation for silicone oil glaucoma in the pseudophakic eye / Viscotrabeculotomia com irrigação da câmara anterior versus implante de válvula de Ahmed para glaucoma por óleo de silicone em olho pseudofácico

ABSTRACT Purpose: To compare viscotrabeculotomy with anterior chamber irrigation to Ahmed glaucoma valve implantation for secondary glaucoma following silicone oil removal. Methods: A prospective study was conducted on 43 vitrectomized pseudophakic eyes with persistent glaucoma after silicone oil removal. Patients were randomized to either viscotrabeculotomy with anterior chamber irrigation or Ahmed glaucoma valve implantation. All patients were examined on day 1, week 1, and months 1, 3, 6, 9, 12, 18, and 24 postoperatively. Postoperative complications were noted. Success was defined as an intraocular pressure between 6 and 20 mmHg and with an intraocular pressure reduction of >30% compared with the preoperative intraocular pressure. Results: There were 22 eyes in the viscotrabeculotomy with anterior chamber irrigation and 21 eyes in the Ahmed glaucoma valve implantation group. The mean preoperative and postoperative intraocular pressure in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 35.5 ± 2.6 mmHg and 35.5 ± 2.4 mmHg and 16.9 ± 0.7 mmHg and 17.9 ± 0.9 mmHg respectively (p˂0.0001). There was a statistically significant intraocular pressure reduction at all follow-up time points compared to preoperative values (p˂0.0001) in both groups. The unqualified success rate in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 72.73% and 61.9%, respectively. A minimal self-limited hyphema was the most common complication. Conclusions: Both viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation are effective in lowering the intraocular pressure in glaucoma after silicone oil removal with viscotrabeculotomy with anterior chamber irrigation providing greater reduction, higher success rates, and minimal complications.

RESUMO Objetivo: Comparar a viscotrabeculotomia com irrigação da câmara anterior com o implante de válvula de glaucoma de Ahmed para glaucoma secundário após remoção de óleo de silicone. Métodos: Foi realizado um estudo prospectivo de 43 olhos pseudofácicos vitrectomizados com glaucoma persistente após a remoção de óleo de silicone. Os pacientes foram randomizados para viscotrabeculotomia com irrigação da câmara anterior ou implante de válvula de Ahmed. Todos os pacientes foram examinados no primeiro dia, na primeira semana e 1, 3, 6, 9, 12, 18 e 24 meses após a cirurgia. Observaram-se complicações pós-operatórias. O sucesso foi definido como uma pressão intraocular entre 6 e 20 mmHg e uma redução da pressão intraocular >30% em comparação com a pressão intraocular pré-operatória. Resultados: Foram designados 22 olhos para o grupo da viscotrabeculotomia com irrigação da câmara anterior e 21 olhos para o grupo do implante de válvula de Ahmed. A pressão intraocular média pré-operatória foi de 35,5 ± 2,6 mmHg para o grupo da viscotrabeculotomia com irrigação da câmara anterior e pós- e de 35,5 ± 2,4 mmHg no grupo do implante de válvula de Ahmed. e Os valores pós-ope­ratórios foram de 16,9 ± 0,7 mmHg e 17,9 ± 0,9 mmHg para esses mesmos grupos, respectivamente (p<0,0001). Ambos os grupos tiveram uma redução estatisticamente significativa da pressão intraocular em relação aos valores pré-operatórios (p<0,0001) em todos os momentos do acompanhamento. A taxa de sucesso não qualificado nos grupos da viscotrabeculotomia com irrigação da câmara anterior e do implante de válvula de Ahmed foi de 72,73% e 61,9%, respectivamente. A complicação mais comum foi o hifema, autolimitado e mínimo. Conclusões: Tanto a viscotrabeculotomia com irrigação da câmara anterior quanto o implante de válvula de Ahmed são eficazes na redução da pressão intraocular no glaucoma após injeção de óleo de silicone, mas a viscotrabeculotomia com irrigação em câmara anterior proporcionou maior redução da pressão intraocular e maiores taxas de sucesso, com complicações mínimas.

Clinical and surgical outcomes of glaucoma drainage device tube in ciliary sulcus versus anterior chamber in North Indian glaucoma patients

Purpose: To evaluate the outcome of glaucoma drainage device (GDD) insertion of tube through ciliary sulcus (CS) versus anterior chamber (AC) placement in the North Indian population Methods: This retrospective comparative case series included 43 patients in CS group and 24 in AC group, who underwent GDD implantation, from March 2014 to February 2020. The main outcome measures were intraocular pressure (IOP), number of anti?glaucoma medications, best corrected visual acuity (BCVA), and complications. Results: Sixty?seven eyes of 66 patients were included in study with mean follow?up of 25.04 months (range, 12–69 months) in the CS group and 17.4 months (range, 13–28 months) in the AC group. Preoperatively the two groups were similar except for postpenetrating keratoplasty glaucoma (PPKG) and pseudophakic patients, which were higher in the CS group (P < 0.05). Both groups showed statistically insignificant difference in postoperative IOP and BCVA at last follow?up (P = 0.173, P = 0.495, respectively). Postoperative complications were similar, except for corneal decompensation which was significantly higher in the AC group (P = 0.042). Conclusion: Our findings suggest that there was no statistically significant difference in mean IOP between the CS and AC groups at the last follow?up. CS placement of tube of GDD appears to be effective and safe technique. However, CS placement of tube resulted in lesser corneal decompensation and thus should be preferred in pseudophakic/aphakic patients, especially PPKG.

Management of glaucoma with Boston type 1 keratoprosthesis / Manejo do glaucoma em olhos com ceratoprótese Boston tipo 1

ABSTRACT Purpose: To describe the frequency, clinical characteristics, complications, and management of glaucoma in eyes that underwent keratoprosthesis implantation. Methods: Patients who underwent keratoprosthesis surgery between June 2010 and January 2020 were retrospectively evaluated for glaucoma association and prognoses. Results: Among 17 patients who underwent keratoprosthesis surgery, 9 (52.9%) were associated with underlying or keratoprosthesis-induced glaucoma. Five eyes (29.4%) had underlying glaucoma and underwent a glaucoma drainage device implantation at least 6 months before keratoprosthesis surgery. One eye (5.9%) with normal intraocular pressure had glaucoma drainage device implantation at the same session with keratoprosthesis surgery due to high-risk characteristics of anterior segment structures. Four eyes with preexisting glaucoma showed progression after keratoprosthesis surgery. Additional antiglaucomatous treatment was commenced in two eyes whereas implantation of 2nd glaucoma drainage device was performed in two eyes. Postoperative complications in three eyes (100%) with glaucoma drainage device implanted 6 months before or at the same session with aphakic type keratoprosthesis surgery with partial vitrectomy included rhegmatogenous retinal detachment in two eyes and bacterial endophthalmitis in one eye. Migration of silicone oil through the tube to the subconjunctival area was seen after pars plana vitrectomy in one eye. None of the three eyes (0%) that underwent glaucoma drainage device implantation years before keratoprosthesis surgery experienced a posterior segment complication other than glaucomatous progression. Out of 11 eyes with no previous history of glaucoma, 3 (27.3%) showed high intraocular pressure and glaucomatous disc changes after keratoprosthesis surgery, which could be pharmacologically controlled. Conclusions: In this cohort, eyes with preexisting glaucoma were more difficult to manage compared to eyes with de novo glaucoma after keratoprosthesis surgery. Retinal complications appeared more often when glaucoma drainage device implantation was performed no more than 6 months before aphakic type keratoprosthesis surgery with partial vitrectomy.

RESUMO Objetivo: Descrever a frequência, as características clínicas, as complicações e o manejo do glaucoma em olhos submetidos a implantes de ceratoprótese. Métodos: Pacientes submetidos à cirurgia de ceratoprótese entre junho de 2010 e janeiro de 2020 foram avaliados retrospectivamente em termos de glaucoma associado e prognóstico. Resultados: Dos 17 pacientes submetidos à cirurgia de ceratoprótese, em 9 (52,9%) foi constatado glaucoma subjacente ou induzido por ceratoprótese. Cinco olhos (29,4%) tinham glaucoma subjacente e receberam a implantação de um dispositivo de drenagem de glaucoma pelo menos 6 meses antes da cirurgia de ceratoprótese. Um olho (5,9%) com pressão intraocular normal teve implantado um dispositivo de drenagem de glaucoma na mesma sessão da cirurgia de ceratoprótese, devido às características de "alto risco" das estruturas do segmento anterior. Quatro dos olhos com glaucoma preexistente apresentaram progressão após a cirurgia de ceratoprótese. Foi iniciado um tratamento antiglaucomatoso adicional em 2 olhos, enquanto outros 2 olhos receberam o implante de um segundo dispositivo de drenagem de glaucoma. Foram observadas complicações pós-operatórias em 3 olhos (100%) com dispositivo de drenagem de glaucoma implantado 6 meses antes ou na mesma sessão da cirurgia de ceratoprótese tipo afácica com vitrectomia parcial, incluindo descolamento de retina regmatogênico em 2 olhos e endoftalmite bacteriana em 1 olho. Em 1 olho observou-se migração do óleo de silicone para a área subconjuntival através do tubo após vitrectomia via pars plana. Nenhum dos 3 olhos (0%) implantados com dispositivo de drenagem de glaucoma anos antes da cirurgia de ceratoprótese apresentou complicações do segmento posterior, exceto progressão glaucomatosa. Dos 11 olhos sem história prévia de glaucoma, 3 (27,3%) apresentaram alta pressão intraocular e alterações do disco glaucomatoso após cirurgia de ceratoprótese, condições que podem ser controladas clinicamente. Conclusões: Nesta coorte, os olhos com glaucoma pré-existente foram mais difíceis de manejar, comparados àqueles que desenvolveram glaucoma após a cirurgia de ceratoprótese. Apareceram mais complicações retinianas quando o implante do dispositivo de drenagem de glaucoma foi realizado no máximo 6 meses antes da cirurgia de ceratoprótese do tipo afácico com vitrectomia parcial.

Incidence, outcomes, and risk of surgical failure after development of early hypotony following Aurolab aqueous drainage implant surgery

Purpose: To report the incidence, outcomes, and risk of surgical failure after early postoperative hypotony following Aurolab Aqueous Drainage Implant (AADI) surgery for adult and pediatric refractory glaucoma. Methods: Medical records of patients who underwent AADI between January 2013 and March 2017 with a minimum of 2?years follow?up were retrospectively reviewed. Early postoperative hypotony was defined as IOP ?5 mmHg within the first 3 months after AADI. Surgical failure of AADI was defined as IOP >21 mmHg or reduced <20% below baseline on two consecutive follow?up visits after 3 months, IOP ?5 mmHg on two consecutive follow?up visits after 3 months, reoperation for glaucoma or a complication, or loss of light perception vision. Results: Early postoperative hypotony was seen in 15/213 eyes (7%) in the adult group and in 6/101 eyes (6%) in the pediatric group. The onset of hypotony was significantly earlier in the pediatric group (median = 39 days post AADI, IQR = 20–58 days) compared with adult eyes (median = 51 days post AADI, IQR = 30–72 days) (P = 0.02). Eyes with early postoperative hypotony did not have an increased risk of cumulative surgical failure as compared with eyes without hypotony in both adult (33.3% vs. 23.7%; P = 0.48) and pediatric (33.3% vs. 13.7%; P = 0.16) refractory glaucoma. All eyes recovered from hypotony, though one adult eye developed retinal detachment and one pediatric eye developed corneal decompensation and lost vision. Conclusion: Early postoperative hypotony was an infrequent complication post AADI and occurred earlier in pediatric eyes. Early postoperative hypotony did not increase risk of surgical failure up to 2 years.

New-Onset Post-Operative Atrial Fibrillation in Patients Undergoing Coronary Artery Bypass Grafting Surgery - A Retrospective Case-Control Study

ABSTRACT Introduction: New-onset postoperative atrial fibrillation (POAF) is a common complication following coronary artery bypass grafting (CABG) surgery. Objective: To explore predictive factors and potential mechanisms of new-onset POAF in isolated off-pump CABG patients. Methods: Retrospective observational case-control study of 233 patients undergoing isolated off-pump CABG surgery between August 2018 and July 2020 at the Department of Thoracic and Cardiovascular Surgery, the Affiliated Drum Tower Hospital of Nanjing University Medical School. Associations between predictor variables and new-onset POAF were identified. The main outcome was new-onset POAF after CABG surgery. Results: A total of 75 (32.19%) patients developed new-onset POAF after CABG surgery. The new-onset POAF patients had advanced age, higher baseline systolic blood pressure, more preoperative use of diuretic drug, more transfusion of blood products, atrial dilation and postoperative positive inotropic drug treatment. Nineteen variates entered the multivariable logistic regression model with a Hosmer-Lemeshow test score of 7.565 (P=0.477). Postoperative left atrial enlargement, postoperative drainage in the first 24 hours and total length of hospital stay were statistically significant, while postoperative right atrial enlargement (OR and 95% CI, 7.797 [0.200, 304.294], P=0.272) and left atrial enlargement (3.524 [1.141, 10.886], P=0.029) assessed by echocardiography had the largest OR value. Conclusion: Atrial enlargement is strongly associated with new-onset POAF in patients with isolated off-pump CABG, thus it highlights the advantage of echocardiography as a useful tool for predicting new-onset POAF. Careful monitoring and timely intervention should be considered for these patients.

Assessment of Rare Case on Patient with Filariasis-Associated Bilateral Pleural Effusion

@#Bilateral pleural effusion is fluid accumulation in both lungs of pleural spaces. The clinical manifestations of bilateral pleural effusion (chylothorax) caused by filariasis are so rare that they are often challenging to diagnose. This case study described a 21-year-old woman, domiciled in Sumatra, with complaints of shortness of breath and swollen legs. Radiological examination results found bilateral pleural effusion. Initially, it was suspected that the effusion was caused by tuberculosis, Systemic Lupus Erythematosus (SLE), and malignancy; however, treatments for these did not improve the patient’s condition. A Water Seal Drainage (WSD) was inserted and a chylous or chylothorax pleural effusion was obtained, and microfilaria was founded in the nocturnal blood examinations. Oxygen and nursing interventions were administered using lung expansion and postural drainage techniques, supported by education on effective coughing and deep breathing, along with the fulfillment of nutritional needs and dietary adjustments

Lower Body Perfusion Reduces the Morbidity of Postoperative Acute Kidney Injury in Type A Dissection: A Propensity-Matched Analysis

ABSTRACT Introduction: Lower body perfusion (LBP) is a technique used to provide blood perfusion to distal organs and spinal cord during circulatory arrest. However, the effect of LBP on the prognosis of aortic arch surgery, especially on postoperative renal function, remains unclear. Methods: A total of 304 patients with acute type A aortic dissection who underwent total aortic arch replacement combined with frozen elephant trunk implantation between May 2016 and December 2021 were retrospectively analyzed. The patients were divided into LBP group (group L, n=85) and non-LBP group (group NL, n=219). Routine lower body circulatory arrest was applied during operation in group NL, and antegrade LBP combined was applied during operation in group L. Perioperative data were recorded. Propensity score matching was used for statistical analysis. Results: After propensity score matching, 85 pairs of patients were successfully matched. Two groups significantly differed in circulatory arrest time (six minutes vs. 30 minutes, P=0.000), cross-clamping time (101 minutes vs. 92 minutes, P=0.010), minimum nasopharyngeal temperature (29.4ºC vs. 27.2ºC, P=0.000), and highest lactate value during cardiopulmonary bypass (2.3 μmol/L vs. 4.1 μmol/L, P=0.000). Considering the postoperative indicators, the drainage volume (450 mL vs. 775 mL, P=0.000) and the incidence of level I acute kidney injury (23.5% vs. 32%, P=0.046) in group L was lower than those in group NL. Conclusion: LBP resulted as a safe and feasible approach in aortic arch surgery, as it could significantly shorten the circulatory arrest time, which might reduce the incidence of postoperative level I acute kidney injury.

Plasma Calcium Level and C-Reactive Protein Albumin Ratio Affect Severe Bleeding After Coronary Artery Bypass Grafting

ABSTRACT Objective: In this study, we aimed to determine whether plasma calcium level and C-reactive protein albumin ratio (CAR) as well as other demographic and hematological markers are related in predicting severe bleeding after coronary artery bypass grafting (CABG). Methods: A total of 227 adult patients who underwent CABG at our hospital between December 2021 and June 2022 were prospectively studied. Total amount of chest tube drainage was evaluated within the first 24 hours postoperatively or until the patient was re-explored for bleeding. The patients were divided into two groups - Group 1, patients with low amount of bleeding (n=174), and Group 2, patients with severe bleeding (n=53). Univariate and multivariate regression analyzes were performed to determine independent parameters related to severe bleeding within the first 24 hours after surgery. Results: When the groups were compared in terms of demographic, clinical, and preoperative blood parameters; cardiopulmonary bypass time and serum C-reactive protein (CRP) levels were found to be significantly higher in Group 2 compared to the low bleeding group. In addition, lymphocytes, hemoglobin, calcium, albumin, and CAR were found to be significantly lower in Group 2. In multivariate analysis, calcium, albumin, CRP, and CAR were found to be independent predictors of significant association with excessive bleeding. A cut-off value of 8.7 (94.3% sensitivity and 94.8% specificity) for calcium and 0.155 (75.4% sensitivity and 80.4% specificity) for CAR predicted excessive bleeding. Conclusion: Plasma calcium level, CRP, albumin, and CAR can be used to predict severe bleeding after CABG.

Acute Paraplegia Result from Spinal Ischemia Nine Years After Hybrid Total Arch Repair with Frozen Elephant Trunk: A Case Report

ABSTRACT Spinal cord ischemia due to decreased cord perfusion is a devastating complication in patients with thoracoabdominal dissection following frozen elephant trunk (FET) repair surgery. However, rare occurrence of spinal cord ischemia leading to paraplegia after long-term follow-up of FET repair has been reported. Here, we describe a case of spinal cord ischemia resulting in paraplegia nine years after hybrid total arch repair with FET. Cerebrospinal fluid drainage and serial treatment were utilized to decrease intraspinal pressure and increase blood flow to the spinal cord. Three months after the onset of paraplegia and with treatment and rehabilitation, the patient recovered to walk.

Scleral communication between Glaucoma drainage device capsule and the suprachoroidal space simulating amelanotic choroidal melanoma / Comunicação escleral entre a cápsula de dispositivo de drenagem para glaucoma e o espaço supracoroidal simulando melanoma de coroide amelanótico

ABSTRACT This is a case report involving a 56-year-old male patient with a history of pars plana vitrectomy due to a rhegmatogenous retinal detachment in the right eye that resulted in the implantation of a drainage device after the patient developed secondary glaucoma. Two years after the device's implantation, the patient was referred to our care as his visual acuity had decreased to 20/200 (1.00 LogMAR). At the fundus evaluation, a choroidal amelanotic elevation was observed at the upper temporal equator, and a potential diagnosis was made of amelanotic choroidal melanoma. The ultrasound exam visualized the patient's implanted superotemporal justabulbar drainage device, which revealed a transscleral communication from the plate fibrocapsular's draining space to the suprachoroidal space (fistula). The ultrasound also revealed a focal pocket of choroidal detachment in the patient's superotemporal region, simulating an amelanotic choroidal melanoma. A new pars plana vitrectomy was performed to remove the internal limiting membrane without repercussions at the fistula site. The patient's recovery progressed well, and he regained a visual acuity of 20/70 (0.55 LogMAR). To the best of our knowledge, this is the first case report of this condition.

RESUMO Relato de caso de paciente 56 anos, sexo masculino, com histórico de vitrectomia via pars plana por descolamento de retina em olho direito e posterior implante de dispositivo de drenagem por glaucoma secundário. Dois anos após o procedimento foi encaminhado ao serviço por baixa de acuidade visual (AV) de 20/200 (1.00 LogMAR). À fundoscopia, observou-se uma elevação amelanótica temporal no equador com hipótese diagnóstica de melanoma de coroide amelanótico. O exame de ultrassom mostrou implante de dispositivo de drenagem justabulbar temporal superior com comunicação transescleral para espaço subcoroidal (fístula), sugerindo bolsão focal de descolamento de coroide em equador temporal superior simulando melanoma de coroide amelanótico. O paciente foi abordado cirurgicamente devido membrana epirretiniana com nova vitrectomia via pars plana para peeling de membrana limitante interna, sem repercussões no local da fístula, evoluindo bem com acuidade visual de 20/70 (0.55 LogMAR). Ao nosso conhecimento, este é o primeiro caso relatado nessa condição.
