O desamparo em Freud e a política como ruptura dos possíveis / Helplessness in Freud and politics as a rupture of the possible / Le délaissé chez Freud et la politique comme rupture du possible / Lo desamparo en Freud y la política como ruptura de lo posible

Este trabalho visa delinear o conceito de desamparo por meio da metapsicologia freudiana e como isso implica outra forma de pensar a política. Desse modo, o desamparo não é concebido unicamente como a vulnerabilidade do bebê ao nascer, mas, também, como a falta de respostas às excitações internas. Tal estado de desamparo é radicalizado a partir da concepção de pulsão de morte construída por Freud. A pulsão de morte gera processos de desabamentos, rupturas, desligamentos e despossessão, essenciais para a própria vida se complexificar. Nesse sentido, propomos o desamparo como afeto político central quando pensamos em transformação. A partir do desabamento de si e da abertura radical ao contato do outro, podemos experimentar outras formas de experiências, outras formas de afetação e, consequentemente, a construção de corpos políticos rumo à transformação política radical

This paper outlines the concept of helplessness through Freudian metapsychology and by doing so imply a new way of thinking about politics. Helplessness is not conceived simply as the newborn's vulnerability, but also as the lack of response to internal excitements. Such an estate is radicalized by Freud's concept of death drive, which generates processes of collapsing, ruptures, unplugging and dispossession that are essential for turning life complex. In this sense, we propose helplessness as a main political affection when referring to transformation. By the collapse of oneself and the radical opening to contact with others, one may experience other ways of experiencing and of being affected and, consequently, the construction of political bodies leading to the radical transformation of politics

Cet article présente le concept de délaissé à travers la métapsychologie freudienne et, ce faisant, lui imprime une nouvelle façon de penser la politique. Le délaissé n'est pas simplement conçu comme la vulnérabilité du nouveau-né, mais aussi comme une absence de réponse aux excitations internes. Tel état est radicalisé par le concept de pulsion de mort de Freud, qui produit des processus de glissement, de rupture, d'arrêt et de dépossession essentielles à la complexification de la vie. En ce sens, nous proposons le délaissé comme principale affection politique lorsqu'il est question de transformation. Par le glissement de soi-même et l'ouverture radicale au contact avec les autres, nous pouvons expérimenter d'autres façons de vivre et d'être affecté et, par conséquent, la construction de corps politiques vers à la transformation politique radicale

Este artículo pretende esbozar el concepto de desamparo a través de la metapsicología freudiana y cómo esto implica otra forma de pensar sobre política. De esa manera, la impotencia no solo se concibe como la vulnerabilidad del bebé al nacer, sino también debido a la falta de respuestas a las excitaciones internas. Tal estado de desamparo se radicaliza desde la concepción del impulso de muerte construido por Freud. El impulso de la muerte genera procesos de colapsos, rupturas, desconexiones y desposesión esenciales para que la vida misma se vuelva más compleja. En este sentido, proponemos lo desamparo como un afecto político central cuando pensemos en la transformación. Desde el colapso de uno mismo y la apertura radical al contacto con el otro, podemos experimentar otras formas de experiencias y otras formas de afectación y,en consecuencia, la construcción de cuerpos políticos hacia una transformación política radical

Uso de balón subacromial en lesión masiva irreparable del manguito rotador

La lesión del manguito rotador es una causa importante de dolor y disfunción del hombro. El tratamiento de las roturas masivas e irreparables del manguito rotador sigue siendo un gran reto para los ortopedistas por su complejidad y severidad. Una de las alternativas prometedoras para su manejo es el uso del balón subacromial. Presentamos el caso de una mujer de 67 años con diagnóstico de rotura masiva e irreparable del manguito rotador en el hombro derecho (grado III de Patte, grado IV Goutallier y grado II de Hamada) sin artrosis glenohumeral, tenosinovitis del bíceps y subescapular íntegro. La escala de constant preoperatorio fue de 40 puntos. Se realizó una reparación parcial artroscópica del tendón supraespinoso e infraespinoso asociado a una tenodesis suprapectoral del bíceps y la colocación del balón subacromial. La paciente realizó rehabilitación con mejoría de los arcos de movilidad, disminución del dolor e incremento de la fuerza del hombro derecho. La escala de constant postoperatorio fue de 80 puntos a la semana doce. El balón subacromial es una buena alternativa de tratamiento para las lesiones irreparables del manguito rotador con resultados óptimos a corto plazo en cuanto a dolor y función.

The rotator cuff injury is a significant cause of shoulder pain and dysfunction. Treating massive and irreparable rotator cuff tears remains a major challenge for orthopedists due to their complexity and severity. One promising alternative for managing these cases is the use of subacromial balloons. In this study, we present the case of a 67-year-old woman diagnosed with a massive and irreparable rotator cuff tear in her right shoulder (Grade III Patte, Grade IV Goutallier, and Grade II Hamada), without glenohumeral arthritis, intact biceps tenosynovitis, and subscapularis. The preoperative Constant score was 40 points. The patient underwent partial arthroscopic repair of the supraspinatus and infraspinatus tendons, along with a suprapectoral biceps tenodesis and subacromial balloon placement. Postoperative rehabilitation led to improved range of motion, reduced pain, and increased strength in the right shoulder. The postoperative Constant score reached 80 points at the twelve-week mark. The subacromial balloon proves to be a promising treatment alternative for irreparable rotator cuff injuries, providing optimal short-term results in terms of pain relief and functionality.

Acute Distal Biceps Tendon Injury: Diagnosis and Treatment / Lesões agudas do tendão distal do bíceps: Diagnóstico e tratamento

Abstract Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques. Although there is no clinical evidence to recommend one fixation method over the other, biomechanical studies show that the cortical button resists better to failure. Although surgical treatment led to an 89% rate of return to work in 14 weeks, the recovery of high sports performance occurred in 1 year, with unsustainable outcomes.

Resumo As lesões agudas do tendão distal do bíceps se apresentam, clinicamente, com uma dor súbita associada a perda aguda de força de flexão e supinação. Seu principal mecanismo de lesão ocorre durante contração excêntrica do bíceps. O "Hook Test" é o principal teste semiológico, sendo o mais sensível e específico. A ressonância magnética, exame padrão ouro para o diagnóstico, pode fornecer informações sobre a integridade, identificando as lesões parciais e/ou completas. O tratamento cirúrgico pode ser realizado por duas vias principais: anterior e por dupla via porém as técnicas de reinserção tendínea são diversas não havendo evidência clínica que recomende um método de fixação em detrimento ao outro; embora o botão cortical apresente maior resistência a falha nos estudos biomecânicos. Com o tratamento cirúrgico o retorno as atividades laborais foi de 89% em 14 semanas (média) porém ao esporte de alto rendimento o prazo foi longo, média de 1 ano, e não duradouro.

Assessing the validity of flap motility sign in predicting the extent of anterior capsular tears in phacoemulsification

Capsulorhexis is an integral step of cataract surgery, and continuous curvilinear capsulorhexis is crucial during phacoemulsification to prevent intraoperative complications. However, sometimes during phacoemulsification in complicated and hard cataract cases, rhexis extension may occur, resulting in posterior capsular rent, nucleus drop, cortex drop, and aphakia. It may not always be possible to continue with phacoemulsification in all cases. In this perspective, the authors describe a novel flap motility sign (FMS) to predict the extent of anterior capsular tear during phacoemulsification. A total of 21,678 patients underwent phacoemulsification for three years, from July 2016 to June 2019. One hundred and twenty-one patients had an anterior capsular tear. There were 102 cases (84.3%) with pre-equatorial tears and 19 cases (15.70%) with postequatorial tears. All pre-equatorial flaps were everted and fluttering, and all postequatorial flaps were inverted and nonfluttering. Posterior capsule rupture (PCR) was observed in all 19 cases of postequatorial flaps (100%). No PCR was observed in patients with fluttering and everted flaps (0%). In-the-bag and scleral-fixated intraocular lens implantations succeeded in pre-equatorial and postequatorial tears, respectively. There was no case of a nucleus drop. This study validates FMS as a predictor for identifying the extent of anterior capsular tears, thereby determining the endpoint of safe phacoemulsification and the site for intraocular lens implantation. Pre-equatorial tears allow for the continuation of safe phacoemulsification and in-the-bag intraocular implantation. Postequatorial tears necessitate timely conversion to small-incision cataract surgery or extracapsular cataract extraction.

Ruptura prematura de membranas ovulares / Premature rupture of ovular membranes

La ruptura prematura de las membranas ovulares se define como la pérdida de la integridad del amnios y corion antes del inicio del trabajo de parto, afecta el 3 % de los embarazos, causa un tercio de los partos pretérminos, los cuales ocupan el 10,49 % de los nacimientos y es el origen de altos índices de morbimortalidad perinatal. En la actualidad, el manejo de esta patología se orienta principalmente en evitar los factores de riesgo, hacer un diagnóstico adecuado, determinar la edad gestacional en que ocurre, realizar el monitoreo exhaustivo del bienestar materno-fetal y en decidir el momento idóneo de finalización de la gestación para minimizar sus complicaciones. Debido a la compleja y lábil estructura histológica de las membranas ovulares, se ha dejado a un lado el tratamiento directo de la entidad el cual sería sellar o reparar el defecto en sí. En los últimos años, numerosos estudios y protocolos clínicos de prestigiosos centros asistenciales han servido como guía para el manejo de esta entidad, pero en muy pocos se observa una terapia destinada a la reparación de dichas membranas o en sellar tal defecto. Las evidencias científicas demuestran que la regeneración y reparación de las membranas es lenta y compleja y los tratamientos propuestos para reparar o sellar su defecto no han gozado de la aceptación científica para su aprobación, sin embargo, el uso del parche hemático transvaginal endocervical autólogo luce como una alternativa terapéutica prometedora(AU)

The premature rupture of the ovular membranes is defined as the loss of the integrity of the amnion and chorion before the on set of labor, affects 3% of pregnancies, causes athird of preterm births which occupy 10,49% of births and is the origin of high rates of perinatal morbidity and mortality. At present, the management of this pathology is mainly oriented towards avoiding risk factors, making an adequate diagnosis, determining the gestational age in which it occurs, carrying out exhaustive monitoring of maternal-fetal well-being and deciding the ideal moment to end the treatment. Pregnancy to minimizeits complications. Due to the complex and labile histological structure of the ovular membranes, the direct treatment of the entity has been set a side, which would be to seal or repairthe defect it self. In recent years, numerous studies and clinicalprotocols from prestigious health care centers have served as aguide for the management of this entity, but very few have observed a therapy aimed at repairing said membranes or sealing such a defect. Scientific evidence shows that the regeneration and repair of the membranes is slow and complex and the treatment sproposed to repair or seal their defect have not enjoyed scientific acceptance for their approval, how ever, the use of the autologous endocervical transvaginal blood patch looks like a promising therapeutic alternative(AU)

Rotura traumática simultánea y bilateral del tendón del cuádriceps en un paciente fisicoculturista: informe de caso y revisión de la literatura / Simultaneous bilateral traumatic quadriceps tendon rupture in a bodybuilding patient: case report and literature review

La rotura traumática, simultánea y bilateral del tendón cuadricipital es una lesión infrecuente, generalmente asociada a otras enfermedades sistémicas tales como insuficiencia renal o trastornos endocrinos. Presentamos el caso de un varón sano y atleta de 38 años que sufrió esta lesión mientras realizaba una sentadilla en el gimnasio. (AU)

The traumatic bilateral and simultaneous quadriceps tendon rupture is a rare injury, usually associated with other systemic diseases such as renal insufficiency or endocrine disorders. We present the case of a 38-year-old healthy male athlete who sustained this injury while performing a squat at the gym. (AU)

The deceptive coloboma

Background: Scleral fistulas are known to develop following blunt trauma in patients with retinochoroidal coloboma. These cases can be managed by surgical options such as silicone buckles, or with glue and scleral patch graft. Some cases have been shown to close spontaneously. We report the first?ever case managed by vitrectomy, endophotocoagulation, and gas tamponade. Purpose: We present a rare and interesting case of an atypical choroidal coloboma with traumatic scleral fistula due to blunt trauma manifesting with hypotony?related disc edema, maculopathy, and chorioretinal folds, which was managed surgically with vitrectomy, endophotocoagulation, and gas tamponade with a good anatomical and visual outcome. Synopsis: The video contains the case description and surgical management of a traumatic scleral fistula in a patient with atypical superotemporal choroidal coloboma. The patient developed hypotonic maculopathy and disc edema after 3 months following a blunt trauma sustained in a road traffic accident. A scleral fistula was suspected at the temporal edge of the coloboma but could not be accurately localized. In addition, due to the edge effect of the coloboma, the external repair was difficult. Hence, vitrectomy with internal tamponade was attempted. Highlights: The video highlights a different surgical approach to managing a traumatic scleral fistula at the edge of a retinochoroidal coloboma. There was a risk of leakage of intravitreal fluid into the orbit through the fistula; however, the gas bubble gave a better tamponade due to higher surface tension. It sealed the fistula presumably by creating a trap?door?like effect. The endophotocoagulation helped create adhesion between the tissues at the edge of the coloboma effectively sealing it. This was followed by a rapid recovery of the hypotony?related problems with good vision. Traumatic scleral fistula, at a difficult place such as the edge of a coloboma, can be successfully closed from an internal approach with vitrectomy, endolaser, and gas tamponade.

RETINA ON CORNEA IN CASE OF MECHANICAL OCULAR INJURY: A CASE REPORT

Ocular injuries are one of the major factors for mono-ocular blindness in adult population. Majority of mechanical ocular injuries occurs in factories. Our patient had injury with grinder blade. On examination, vision was no perception of light in right eye, corneoscleral tear along with lens and vitreous in the wound. Ocular trauma score was 1 with chances of visual recovery nil. After primary treatment, when we had taken patient under general anaesthesia, we found whole retina lying over cornea which was a rare event. We excised that tissue and tear repair was done. None of the factors which can lead to expulsive haemorrhage was observed in patient. We have seen many patients with extensive corneoscleral tear but never seen retina coming out of the wound. We recommend to use all protective equipments for workers to prevent industrial ocular injuries.

Retrospective analysis of the role of anterior segment optical coherence tomography and outcomes of cataract surgery in posterior polar cataract

Purpose: To evaluate the visual and surgical outcomes of cataract surgery in patients with posterior polar cataract (PPC) and to evaluate the benefits of preoperative anterior segment optical coherence tomography (AS?OCT). Methods: This was a retrospective, single?center study. Case records of patients diagnosed with PPC who underwent cataract surgery either by phacoemulsification or manual small?incision cataract surgery (MSICS) from January to December 2019 were analyzed. Data collected include demographic details, preoperative best corrected visual acuity (BCVA), AS?OCT, type of cataract surgery, intraoperative and postoperative complications, and visual outcome at 1?month follow?up. Results: One hundred patients were included in the study. Preoperative posterior capsular defect was noted on AS?OCT in 14 patients (14%). Seventy?eight underwent phacoemulsification and 22 underwent MSICS. Intraoperatively, posterior capsular rupture (PCR) was seen in 13 patients (13%) and cortex drop was noted in one among them (1%). Out of 13 PCRs, 12 were found to have posterior capsular dehiscence preoperatively in AS?OCT. The sensitivity of AS?OCT for detecting posterior capsule dehiscence was 92.3% and specificity was 97.7%. The positive predictive value and negative predictive value were 85.7% and 98.8%, respectively. There was no significant difference in the incidence of PCR between phacoemulsification and MSICS (P = 0.475). The mean BCVA at 1 month was found to be better with phacoemulsification than MSICS (P = 0.004). Conclusion: Preoperative AS?OCT has excellent specificity and negative predictive value in identifying posterior capsular dehiscence. It thus helps to plan the surgery and counsel patients appropriately. Both phacoemulsification and MSICS provide good visual outcome with similar complication rates.

Rotura espontánea de vena ilíaca: una causa infrecuente de abdomen agudo hemorrágico / Spontaneous rupture of the iliac vein: a rare cause of intra-abdominal hemorrhage

RESUMEN La rotura espontánea de la vena ilíaca es una causa poco frecuente de hemorragia retroperitoneal exanguinante. Generalmente está asociada con un traumatismo y las lesiones iatrogénicas durante la cirugía de hemiabdomen inferior o pelviana. Ocurre con frecuencia del lado izquierdo y afecta indistintamente a la vena ilíaca común como a la externa. Con el objetivo de destacar las características clínicas e imagenológicas de esta infrecuente entidad, presentamos un caso fatal de rotura espontánea de la vena ilíaca externa izquierda. El tratamiento se basa en la reparación quirúrgica abierta o, en casos seleccionados, en la colocación de prótesis por vía endovascular. Es necesario un alto índice de sospecha, ya que el diagnóstico y el tratamiento tempranos son fundamentales para mejorar las altas tasas de morbimortalidad que conlleva esta entidad.

ABSTRACT Spontaneous rupture of the iliac vein is a rare cause of fatal retroperitoneal hemorrhage that is generally associated with trauma and iatrogenic injury during lower abdominal or pelvic surgery. It usually occurs in the left common and external iliac veins. We report a fatal case of spontaneous rupture of the left external iliac vein to emphasize the clinical and imaging characteristics of this rare condition. Treatment is based on open surgical repair or endovascular stenting in selected cases. High level of suspicion is essential for early diagnosis and treatment to improve the associated morbidity and mortality.

Hypersonic vitrectomy in intraoperative posterior capsular rupture with retained nuclear fragments

In our report, we present the hypersonic vitrectomy (Vitesse, Bausch and Lomb) being employed for anterior vitreous liquefaction and removal in posterior capsular rupture. The capsular tear with nucleus drop during conventional phacoemulsification was managed by vitrectomy using the hypersonic vitrector after posterior-assisted levitation followed by intraocular lens (IOL) implantation. The minimal cortical and epinuclear lens particles in the anterior chamber and vitreous were also liquefied with a stoke length of 30 to 40 ?m and aspirated via the Vitesse vitrectomy system. The same probe performs the vitrectomy and the nucleus removal. The postoperative period was uneventful with clear cornea, normal fundus, and 20/20 best-corrected visual acuity (BCVA). The hypersonic vitrectomy utilizes the ultrasound power of 29.5 kHz and a stoke length of 0 to 60 ?m for liquefaction of the vitreous. It can be a safe alternative for vitrectomy and lens removal in a single setting.

Introduction: The study was conducted to evaluate IOP management by surgical modalities such as combined trabeculectomy and phacoemulsification and phacoemulsification surgery alone. Vision impairment is a major public health problem and the burden is increasing with increase in aged population. This study wasAims And Objectives: undertaken for study the IOP management by surgical modalities such as combined trabeculectomy and phacoemulsification and phacoemulsification surgery alone. A pre-designed prospective study was conducted at the OPD of upgraded Department of Ophthalmology at LLRM Medical College, Meerut. A total of 60 patients were divided in to two equal groups randomly and studied. Majority of the patients in both the groups wereObservation And Result: aged between 61 – 70 years. Females outnumbered males in this study which was statistically significant between the two groups. The mean pre- operative intra ocular pressure was 23.3 mm Hg in combined surgery group and 23.9 mm Hg in cataract surgery alone group. Mean Intra ocular pressure decreased regularly in each follow up more in combined group than the cataract surgery alone group. The mean intra ocular pressure after 1 years follow up in combined surgery group was 10.8 mm Hg and 13.4 mm Hg in the cataract surgery alone groups which was statistically significant. Mean BCVA before the operation was 3.2 in combined surgery group and 3.8 in cataract surgery before surgery. Mean BCVA declined after 1 year of follow up in combined surgery group was 1.9 and 2.7 in cataract surgery alone group which was statistically significant. The surgery success was complete in 80.0% of the combined surgery group and 60% of the cataract alone group. Criteria For Failure Of Surgeries Ÿ The IOP >23 MMHG at the end of 1 year or Ÿ The IOP not reduced by 20 % from base line at the end of 1 year Conclusion: This study was mainly undertaken to study the efficacy of combined trabeculectomy with cataract extraction and cataract only on primary angle closure glaucoma. This study had found that, the reduction of intra ocular pressure in both the groups but more prominent in combined surgery group than cataract alone surgery group.

A Rare Catastrophe: Three Cases of Aortic Root Dehiscence after Surgery

Abstract Ascending aortic pathologies may be life-threatening. Postoperative aortic root dehiscence is a very rare but extremely dangerous complication with a high mortality rate, and redo surgery is mandatory due to high risk of spontaneous rupture. We present three cases that had undergone Bentall procedure and had postoperative aortic root dehiscence. One of the patients presented with hemiplegia caused by septic embolus while the others had mild symptoms. Dr. Yakut's modified Bentall procedure, the flanged technique, was performed for each patient in redo surgery. Two patients were successfully discharged from the hospital, but one died due to intracranial hemorrhage and multiple organ failure.

Risk factors for posterior capsule rupture in mature cataract surgery: A study of 1302 cases

Purpose: To identify the risk factors predisposing posterior capsule rupture (PCR) during mature cataract surgery. Methods: A total of 1302 consecutive mature cataract cases were included in this retrospective study. A detailed examination was performed for each patient and risk factors including age, gender, systemic diseases, ocular comorbidities, surgeon, and surgery method were recorded. Cases with PCR during surgery were classified as complicated. Multivariate logistic regression analysis with a generalized estimating equations method was applied for statistical analysis. Results: The overall rate of PCR was 7.30% (n=95 eyes). After adjusting for confounders, factors that remained significant on multivariate analysis were strabismus (odds ratio [OR]: 5.70, 95% confidence interval [CI]: 2.17–14.97; P < 0.001), phacodonesis (OR: 4.62, 95% CI: 2.59–8.22; P < 0.001), history of trauma (OR: 4.46, 95% CI: 1.64–12.12; P = 0.003), surgery method (extracapsular cataract extraction/phacoemulsification) (OR: 2.61, 95% CI: 1.60–4.26; P < 0.001), and pseudoexfoliation (OR: 1.94, 95% CI: 1.20–3.16; P = 0. 007). Conclusion: Strabismus, phacodonesis, history of trauma, extracapsular cataract extraction method, and pseudoexfoliation were found to be important risk factors for developing PCR. Appropriate preoperative and perioperative precautions for these higher?risk cases can reduce complications

Association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes

SUMMARY OBJECTIVE: The aim of this study was to evaluate the association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes. METHODS: This retrospective cohort included pregnant women with premature rupture of membranes (between 24 and 33+6 weeks) who used or did not use prophylactic antibiotics. Pearson's chi-square (χ²) test, Student's t-test, and binary logistic regression were used for statistical analysis. RESULTS: A significant effect was observed in patients with premature rupture of membranes using prophylactic antibiotics regarding amniotic fluid index (p=0.007), deepest vertical pocket (p=0.049), duration of antibiotic therapy (p≤0.001), C-reactive protein level upon admission (p≤0.001), leukocyte count upon admission (p=0.007), and length of stay in neonatal intensive care (p=0.047). A significant association was observed between the abovementioned patients and surfactant use during the neonatal period (p=0.04). A higher prevalence of surfactant use was noted in these patients (20.0 vs. 8.7%; p=0.04). CONCLUSION: No association was found between antibiotic prophylaxis and the presence of adverse perinatal outcomes in pregnant women with premature rupture of membranes between 24 and 33+6 weeks of gestation.

Umbilical vascular catheter rupture: a case report and literature review / 中国新生儿科杂志

Objective:To study the clinical characteristics of neonatal umbilical vascular catheter (UVC) rupture.Methods:A neonate with UVC rupture admitted to Neonatology Department of our hospital was retrospectively reviewed. Literature on this subject were searched in the following databases: Chinese Medical Journal full-text Database, CNKI, Wanfang Database, CQVIP database, PubMed, Web of Science, Embase and Cochrane Library (up until March 15 2022). The causes, treatment and prognosis of neonatal UVC rupture were analyzed.Results:In our case, the UVC was accidentally damaged during the removal of the ligature suture. The UVC was ruptured after a slight force was applied to remove the catheter, resulting in approximately 7 cm of UVC remaining in the body. Trans-umbilical vein intervention was performed and the catheter was successfully removed with a lasso under X-ray guidance. A total of 33 UVC rupture cases were included from 15 articles (no case report in China before). In 16 cases (47.1%), the UVCs were accidentally cut off by knife or scissors when removing the catheter. In 3 cases (8.8%), the UVCs were broken during insertion. The UVC was broken in 1 case (2.9%) during flushing the catheter. The causes of the other 14 cases (41.2%) were unknown. 9 cases (26.5%) had clinical manifestations, including respiratory distress, prominent heart murmur, sepsis and limb ischemia. 20 cases (58.8%) showed no clinical features. No data on the other 5 cases (14.7%). 21 cases (61.8%) received vascular intervention removal, 11 cases (32.4%) received surgical removal, 1 case (2.9%) was removed with tweezers, and 1 case (2.9%) died before UVC was removed. Among the neonates receiving surgical treatment, 1 case died of sepsis on the second day after surgery and 1 case had sequela of limb ischemia. 2 cases had postoperative vasospasm and embolism after vascular intervention with overall good prognosis.Conclusions:The rupture of UVC in neonates is rare and mainly related with knife and scissors injury.

The natural decline and death course of hepatic cystic echinococcsis / 中华消化外科杂志

Hepatic cystic echinococcosis (HCE) is a global public health problem. At present, the research of echinococcosis mainly focuses on etiology, epidemiology, immunology, imaging and treatment programs, while ignoring the systematic study of its natural decline and death course. The popularization of modern imaging examination methods enable researchers to obtain the clinical data of HCE in different stages, with different imaging features and pathological states. Based on CT imaging features and clinical practice, the authors discuss the natural decline and death course of HCE, in order to provide new ideas for its diagnosis and treatment.

Risk factors and treatment progress of spontaneous rupture and hemorrhage in hepatocellular carcinoma / 国际外科学杂志

Hepatocellular carcinoma is one of the most common malignant tumors in clinical practice, and China has the highest incidence in the world. Spontaneous rupture of hepatocellular carcinoma is a serious complication of hepatocellular carcinoma. Its mechanism and risk factors are complex, including tumor size, location, hypertension, cirrhosis, HBsAg positivity, obesity and receiving targeted therapy with sorafenib, which may be its influencing factors. In recent years, the treatment methods of rupture and hemorrhage of hepatocellular carcinoma have been continuously improved and developed, including conservative treatment, transcatheter arterial chemoembolization, emergency hepatectomy, staged hepatectomy, etc.Transcatheter arterial chemoembolization followed by selective surgery is the most effective treatment at present. This article reviews the risk factors and treatment progress of rupture and hemorrhage of hepatocellular carcinoma, in order to provide reference for the direction of research on rupture and hemorrhage of hepatocellular carcinoma, so as to improve the prognosis and prolong the survival time of patients with early detection, early prevention and early treatment.

Extracardiac Rupture of Giant Left Valsalva Sinus Aneurysm / 日本心臓血管外科学会雑誌

We report a case of extracardiac rupture of the left Valsalva sinus aneurysm, which is an extremely rare and fatal lesion. The three drugs, clindamycin, ethambutol and rifampicin, had been administered for eleven years because of lung mycobacterium infection. An emergency surgery was performed because of cardiac tamponade. The left Valsalva sinus was entirely enlarged without an aneurysmal neck. The other Valsalva sinuses seemed to be almost normal. The aneurysmal wall adhered the pulmonary artery and the left atrium. The left descending and circumflex arteries independently originated from the aneurysmal wall. The left main trunk seemed to become a part of the aneurysmal wall. Additionally the intraoperative transesophageal echocardiography showed severe aortic regurgitation. The Bio-Bentall procedure was performed. The right coronary artery was reconstructed with the Carrel patch method and the saphenous vein grafts were anastomosed to the proximal portions of the left anterior descending and circumflex arteries, individually. On the thirty-third postoperative day, the patient was discharged uneventfully expect for the delayed sternal closure on the second postoperative day. Five and half years after surgy, the patient is living a normal life and rifampicin has been administered without any anticoagulation drugs.

Acute inferior myocardial infarction combined with papillary muscle rupture: A case report / 中南大学学报(医学版)

The incidence of acute myocardial infarction (AMI) is increasing. Acute papillary muscle rupture is one of the serious and rare mechanical complications of AMI, which occurs mostly in inferior and posterior myocardial infarction. A patient with acute inferior myocardial infarction developed pulmonary edema and refractory shock, followed by cardiac arrest. After cardiopulmonary resuscitation (CPR), revascularization of criminal vessels was carried out by emergency percutaneous transluminal coronary angioplasty (PTCA) under the support of intra-aortic balloon pump (IABP) and extra corporeal membrane oxygenation (ECMO). Although the patient was given a chance for surgery, his family gave up treatment due to unsuccessful brain resuscitation. It reminds that mechanical complications such as acute papillary muscle rupture, valvular dysfunction and rupture of the heart should be highly suspected when cardiogenic pulmonary edema and cardiogenic shock are difficult to correct in acute inferior myocardial infarction. Echocardiogram and surgery should be put forward when revascularization of criminal vessels is available.
