Pediatric canalicular laceration repair using the Mini Monoka versus Masterka monocanalicular stent / Correção de laceração canalicular pediátrica usando os stents monocanaliculares Mini-Monoka versus Masterka

ABSTRACT Purpose: One of the most important disadvantages of using Mini Monoka stents in pediatric canalicular laceration repair is premature stent loss. In this study, we aimed to compare clinical outcomes between the use of Mini Monoka and Masterka monocanalicular stents in children and discuss the potential causes of premature stent loss. Methods: The medical records of 36 patients who underwent surgical repair of canalicular lacerations were retrospectively reviewed. Children aged <18 years who underwent canalicular laceration repair with either Mini Monoka or Masterka and had at least 6 months of follow-up after stent removal were included in the study. The patients' demographics, mechanism of injury, type of stent used, premature stent loss, and success rate were analyzed. Success was defined as stent removal without subsequent epiphora and premature stent loss. Results: Twenty-seven children fulfilled our study criteria, and their data were included in the analyses. Mini Monoka was used in 14 patients (51.9%), whereas Masterka was used in 13 patients (48.1%). The preoperative clinical features, including age, sex, and mechanism of injury, were similar between the two groups. The mean age was 8.3 ± 5.5 years in the Mini Monoka group and 7.8 ± 5.9 years in the Masterka group (p=0.61). Three patients in the Mini Monoka group (21.4%) underwent reoperation due to premature stent loss. No premature stent loss was observed in the Masterka group. As a result, the rate of success was 78.6% in the Mini Monoka group, whereas it was 100% in the Masterka group (p=0.22). Conclusions: Even though the two groups did not show any statistically significant difference in success rate, we did not observe any premature stent loss in the Masterka group. Further studies with larger and randomized series are warranted to elaborate on these findings.

RESUMO Objetivo: Uma das desvantagens mais importantes do uso de stents Mini Monoka no reparo de lacerações canaliculares pediátricas é a perda prematura do stent. Neste estudo, objetivamos comparar os resultados clínicos dos stents monocanaliculares Mini Monoka e Masterka em crianças e discutir as possíveis causas da perda prematura do stent. Métodos: Foram incluídos nesta revisão retrospectiva 36 pacientes <18 anos de idade que se submeteram ao reparo cirúrgico de uma laceração canalicular com um stent Mini Monoka ou Masterka e tiveram pelo menos 6 meses de acompanhamento após a remoção do stent. Foram analisados os dados demográficos, o mecanismo da lesão, o tipo de stent utilizado, a ocorrência de perda prematura de stent e o sucesso da intervenção. O sucesso foi definido como a ausência de epífora após a remoção do stent, sem a perda prematura deste. Resultados: Vinte e sete pacientes preencheram os critérios do presente estudo e foram incluídos nas análises. O stent Mini Monoka foi usado em 14 pacientes (51,9%), enquanto o Masterka foi usado em 13 pacientes (48,1%). As características clínicas pré-operatórias, incluindo idade, sexo e mecanismo de lesão, foram semelhantes entre os dois grupos. A média de idade foi de 8,3 ± 5,5 anos no grupo Mini Monoka e de 7,8 ± 5,9 anos no grupo Masterka (p=0,61). Três pacientes do grupo Mini-Monoka (21,4%) tiveram que ser operados novamente por perda prematura do stent. Nenhuma perda prematura do stent foi observada no grupo Masterka. Como resultado, a taxa de sucesso foi de 78,6% no grupo Mini Monoka e de 100% no grupo Masterka (p=0,22). Conclusões: Embora nenhuma diferença estatisticamente significativa tenha sido detectada entre os dois grupos em termos de taxas de sucesso, não observamos nenhuma perda prematura de stent no grupo Masterka. São necessários mais estudos, com séries maiores e randomizadas, para chegar a maiores conclusões sobre esses achados.

Application of Worst lacrimal probe combined with modified lacrimal duct threading intubation in anastomosis of complex canalicular laceration / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the application value of Worst lacrimal probe combined with modified lacrimal duct intubation in anastomosis of complex canalicular laceration.METHODS: Retrospective study. A total of 68 cases(68 eyes)with complex traumatic canalicular laceration treated in the ophthalmology department of the Second Affiliated Hospital of Zunyi Medical University from March 1, 2019 to March 31, 2021 were selected. They were divided into two groups according to the surgical methods, with 36 patients(36 eyes)who were treated with the Worst lacrimal probe to find the broken end of lacrimal duct combined with improved lacrimal duct threading intubation in group A, and 32 patients(32 eyes)who were treated with microscope to find the broken end of lacrimal duct and two-way intubation anastomosis canaliculus intubation in group B. The clinical efficacy, success rate of intraoperative search for the broken end of lacrimal duct, searching time, operation time, the degree of pain, postoperative ocular foreign body sensation and complications were compared between the two groups.RESULTS: The total effective rate of clinical efficacy in patients of group A was higher than that in group B(94% vs. 38%), the success rate of intraoperative search for broken end of lacrimal duct was higher than that in group B(100% vs. 47%), the searching time and operation time were shorter than those in group B, and the score of pain degree was lower than that in group B(all P&#x0026;#x003C;0.05). The postoperative follow-up for 6mo-1a showed that the ocular foreign body sensation score, the incidence of lacrimal punctum rupture and morphological change, and the degree of tear overflow in group A were all lower than those in group B(all P&#x0026;#x003C;0.05).CONCLUSION: Worst lacrimal probe combined with modified lacrimal duct intubation for the treatment of complex traumatic canalicular laceration can find the broken end of lacrimal duct more accurately, shorten the operation time, reduce the pain and foreign body sensation of patients, improve clinical efficacy and reduce the incidence of complications.

Complementary Ureterorenoscopy after extracorporeal Shock Wave Lithotripsy in proximal ureteral stones: success and complications

SUMMARY OBJECTIVE: The aim of this study was to demonstrate the effect of extracorporeal shock wave lithotripsy application on the success and complications of ureteroscopic lithotripsy in proximal ureter stones. METHODS: The data of 87 patients who did not respond to shock wave lithotripsy and underwent ureteroscopic lithotripsy were retrospectively analyzed and classified as group I, and 99 patients who received ureteroscopic lithotripsy as primary treatment were classified as group II. Demographic features, response to treatment, and preoperative and postoperative complications were compared between the two groups. RESULTS: There was no difference between the two groups in terms of gender, operation times, stone sizes, and ureteroscope diameters. (p>0.05). Infective complications such as postoperative fever, pyelonephritis, and urosepsis were similar in both groups (p=0.142, p=0.291, and p=0.948). Stone migration was observed in 10 (11.5%) and 6 (6.1%) patients in groups I and II, respectively (p=0.291). Impacted stone was seen in 47 (54%) patients in group I and in 15 (15.2%) patients in group II (p<0.0001). Mucosal laceration occurred in 11 (12.6%) and 3 (3%) patients in groups I and II, respectively (p=0.028). Ureteral perforation was detected in 3 (3.4%) patients in group I and 1 (1%) patient in group II, whereas ureteral avulsion was not observed in either group (p=0.524). CONCLUSIONS: It was concluded that the application of shock wave lithotripsy before ureteroscopic lithotripsy in proximal ureter stones did not affect the success. Although the results are similar in terms of postoperative infection, shock wave lithotripsy application has been found to increase the risk of stone impaction into the mucosa and ureteral laceration.

Cirugía fetoscópica en síndrome de banda amniótica: comunicación del primer caso exitoso en el Perú con correlación posnatal a los 6 y 12 meses de vida

El síndrome de banda amniótica (SBA) o complejo de disrupción de banda amniótica es aquella malformación congénita que ocurre como consecuencia de bridas amnióticas de etiología heterogénea, patogénesis que involucra una serie de manifestaciones clínicas fetales, tales como constricción, amputación y múltiples defectos craneofaciales, viscerales y de la pared del cuerpo. La prevalencia estimada de SBA oscila entre 1:15,000 y 1:1,200 nacidos vivos. Afecta a ambos sexos por igual. El diagnóstico prenatal puede sospecharse tan pronto como el primer trimestre tardío, cuando las imágenes por ultrasonido detectan anillos de constricción, amputaciones de extremidades y/o defectos craneofaciales. La terapia prenatal puede ofrecer una alternativa de tratamiento con la liberación de anillos de constricción bajo fetoscopia en aquellos fetos que se verían beneficiados con el procedimiento.

Amniotic band syndrome (ABS) or amniotic band disruption complex is a congenital malformation that occurs because of amniotic flanges of heterogeneous etiology, a pathogenesis that involves a series of fetal clinical manifestations, such as constriction, amputation, and multiple craniofacial, visceral and wall defects. The estimated prevalence of ABS ranges from 1:15.000 to 1:1.200 liveborn. It affects both sexes equally. Prenatal diagnosis may be suspected as early as the late first trimester when ultrasound imaging detects constriction rings, limb amputations and/or craniofacial defects. Prenatal therapy may offer an alternative treatment with release of constriction rings through fetoscopy in those fetuses that would benefit from the procedure.

Effect of interrupted suture and continuous suture on perineal rehabilitation of parturients: a Meta-analysis / 中国实用护理杂志

Objective:To explore the effect of perineal lateral incision and continuous suture of deep and superficial Ⅱdegree laceration on postoperative perineum rehabilitation of parturients.Methods:Randomized controlled trials of intervention effects on postoperative maternal wound rehabilitation using continuous sutures and interrupted sutures of mucosal, muscle, and skin layers after perineal lateral resection and Ⅱdegree lacerations were searched in Cochrane Library, PubMed, Medline, Embase, Science direct, China Biology Medicine, China National Knowledge Infrastructune, Wanfang Database, VIP Database. The retrieval time limit was from database establishment to October 1, 2020. using RevMan 5.3 software for statistical processing.Results:After searching and screening, 12 articles were finally included. The total sample size was 2 827 cases. After the two groups used different suture techniques, the results of Meta analysis showed that the pains ( MD=1.02, 95% CI=1.02-1.06), the suture time ( MD=-4.59, 95% CI=-7.29 - -1.91) and the healing condition ( MD=-0.55, 95% CI=-0.71 - -0.39) of the two groups were compared, the differences were significant (all P<0.01). Conclusions:In the suture of perineal lateral incision and Ⅱdegree laceration, continuous suture technique is used to suture the mucosal layer, muscle layer, and cortex, which can reduce the suture time, reduce the pain of the parturient, and is beneficial to the healing of the wound. It can be clinically based on the parturient. It can be used in accordance with the neatness and depth of the mouth and the needs of the parturient.

Effect of nasolacrimal duct packing combined with sodium hyaluronate gel injection in locating the nasal broken end in lacrimal canaliculus anastomosis which is difficult to find the broken end / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the effect of nasolacrimal duct packing combined with sodium hyaluronate gel injection in locating the nasal broken end in lacrimal canaliculus anastomosis which is difficult to find the broken end.METHODS:A total of 13 patients(13 eyes)with traumatic single lacrimal canaliculus rupture were treated in our hospital. RS lacrimal duct drainage tube was inserted into the lacrimal duct from intact lacrimal canaliculus to fill the nasolacrimal duct, then sodium hyaluronate gel was injected to make sodium hyaluronate gel overflow from the nasal broken end of fractured lacrimal canaliculus, which was used to locate the nasal broken end which was difficult to find and completed the lacrimal anastomosis operation.RESULTS: Among the patients with 13 eyes who were difficult to find the broken end, the nasolacrimal duct was filled with RS lacrimal duct drainage tube. After injection of sodium hyaluronate gel, the gel overflowed from the nasal broken end under direct vision of the microscope, and the lacrimal duct drainage tube was successfully inserted, and the success rate of finding the broken end was 100%. Thirteen eyes were extubated after being placed for 3mo, and then were followed up for 6mo. Among them, 9 eyes were cured, 3 eyes were markedly effective and 1 eye was ineffective. The cure rate was 69%, and the total effective rate was 92%.CONCLUSION: A new technique for rapid location of nasal broken end is proposed for patients in which are difficult to find the broken end. This method is simple to operate and requires a relatively low clinical experience. It is suitable for patients with different degrees of single lacrimal canaliculus rupture and can complete complex lacrimal canaliculus rupture anastomosis in a short time.

The efficacy of immediate implantation of macroporous poly(N-[2-hydroxypropyl]-methacrylamide) hydrogel after laceration spinal cord injury in young rats / Eficacia de la implantación inmediata de hidrogel macroporoso de poli (N- [2-hidroxipropil] - metacrilamida) después de una lesión de la médula espinal en ratas jóvenes

SUMMARY: Spinal cord regeneration after mechanical injury is one of the most difficult biomedical problems. This article evaluates the effect of poly(N-[2-hydroxypropyl]-methacrylamide) hydrogel (PHPMA-hydrogel) on spinal cord regeneration in young rats after lateral spinal cord hemi-excision (laceration) at the level of segments T12-T13 (TrGel group). The locomotor function score (FS) and the paretic hindlimb spasticity score (SS) were assessed according to Basso-Beattie-Bresnahan (BBB) and Ashworth scales, respectively, and compared to a group of animals with no matrix implanted (Tr group). Regeneration of nerve fibers at the level of injury was evaluated at ~5 months after spinal cord injury (SCI). One week after the SCI induction, the FS on the BBB scale was 0.9±0.5 points in the Tr group and 3.6±1.2 points in the TrGel group. In the Tr group, the FS in 5 months was significantly lower than in 2 weeks after SCI, while no significant changes in FS were detected in the TrGel group over the entire observation period. The final FS was 0.8±0.3 points in the Tr group and 4.5±1.8 points in the TrGel group. No significant changes in SS have been observed in the TrGel group throughout the experiment, while the Tr group showed significant increases in SS at 2nd week, 6th week, 3th month and 5th month. The SS in 5 months was 3.6±0.3 points on the Ashworth scale in the Tr group and 1.8±0.7 points in the TrGel group. Throughout the observation period, significant differences in FS between groups were observed only in 5 weeks after SCI, whereas significant differences in SS were observed in 2, 3 and 6-8 weeks post-injury. Glial fibrous tissue containing newly formed nerve fibers, isolated or grouped in small clusters, that originated from the surrounding spinal cord matter have been found between the implanted hydrogel fragments. In conclusion, PHPMA-hydrogel improves recovery of the hindlimb locomotor function and promotes regenerative growth of nerve fibers. Further research is needed to clarify the mechanism of this PHPMA-hydrogel effect.

RESUMEN: La regeneración de la médula espinal después de una lesión mecánica es uno de los problemas biomédicos más difíciles. Este artículo evalúa el efecto del hidrogel de poli (N- [2-hidroxipropil] -metacrilamida) (PHPMA-hidrogel) sobre la regeneración de la médula espinal en ratas jóvenes después de la hemiescisión lateral de la médula espinal (lesión) a nivel de los segmentos T12 - T13 (Grupo TrGel). La puntuación de la función locomotora (FS) y la puntuación de espasticidad parética de las patas traseras (SS) se evaluaron de acuerdo con las escalas de Basso- Beattie-Bresnahan (BBB) y Ashworth, respectivamente, y se compararon con un grupo de animales sin matriz implantada (grupo Tr). Se evaluó la regeneración de las fibras nerviosas al nivel de la lesión ~ 5 meses después de la lesión de la médula espinal (LME). Una semana después de la inducción de SCI, el FS en la escala BBB fue 0,9 ± 0,5 puntos en el grupo Tr y 3,6 ± 1,2 puntos en el grupo TrGel. En el grupo Tr, el FS en 5 meses fue significativamente menor que en 2 semanas después de SCI, mientras que no se detectaron cambios significativos en FS en el grupo TrGel durante el período de observación. El FS final fue de 0,8 ± 0,3 puntos en el grupo Tr y de 4,5 ± 1,8 puntos en el grupo TrGel. No se han obser- vado cambios significativos en SS en el grupo TrGel durante el experimento, mientras que el grupo Tr mostró aumentos significativos en SS en la 2ª semana, 6ª semana, 3º mes y 5º mes. La SS en 5 meses fue de 3,6 ± 0,3 puntos en la escala de Ashworth en el grupo Tr y de 1,8 ± 0,7 puntos en el grupo TrGel. A lo largo del período de observación, se observaron diferencias significativas en FS entre los grupos solo en 5 semanas después de la LME, mientras que se observaron diferencias significativas en SS en 2, 3 y 6-8 semanas después de la lesión. Entre los fragmentos de hidrogel implantados se observó tejido fibroso glial que contenía fibras nerviosas recién formadas, aisladas o agrupadas en pequeños grupos, que se originaban a partir de la materia de la médula espinal circundante. En conclusión, PHPMA-hydrogel mejora la recuperación de la función locomotora de las patas traseras y promueve el crecimiento regenerativo de las fibras nerviosas. Se requieren más estudios para aclarar el mecanismo del efecto de hidrogel PHPMA.

Abstract Objective To describe the use of surgical glue to repair perineal trauma during normal delivery. Methods This is a case series study, which was carried out in three moments (up to 2 hours, 12-24 hours and 36-48 hours after delivery) in Itapecerica da Serra, SP. Women who had a normal delivery with perineal trauma with a suture (first or second degree laceration and episiotomy) were included. Perineal trauma was repaired exclusively with Glubran-2® surgical glue. Perineal pain intensity (11-point Visual Numeric Scale), healing process (15-point REEDA scale), satisfaction with repair (5-point Likert scale) were assessed. Data were analyzed in a descriptive and inferential way comparing the three moments. Results The technique of applying the glue and the required amount were defined in a sample of 19 women. Of these, 78.9% had first-degree lacerations, 15.8%, second-degree lacerations and 5.3%, episiotomy. The outcomes at moments 1, 2 and 3 were absence of pain (73.6%, 94.7% and 89.4%), score ≤1 on the REEDA scale (94.7%, 78.9% and 84, two%); 100% were satisfied with the repair at all times. There was no difference by the Friedman test for pain and satisfaction. The healing process showed a difference, but without confirmation in the hoc post-test. Conclusion The glue application proved to be viable for assessment in a larger sample of women, as the results suggest good acceptance by women and low or no pain, adequate healing and high satisfaction with the repair in the first 48 hours after delivery.

Perineal Lacerations: A Retrospective Study in a Habitual-Risk Public Maternity / Lacerações perineais: um estudo retrospectivo em uma maternidade pública de risco habitual

Abstract Objective In around 85% of vaginal births, the parturients undergo perineal lacerations and/or episiotomy. The present study aimed to determine the incidence of lacerations and episiotomies among parturients in 2018 in a habitual-risk public maternity hospital in southern Brazil, and to determine the risk and protective factors for such events. Methodology A retrospective cross-sectional study. Data were obtained from medical records and analyzed using the Stata software. Univariate and multivariate logistic regressions were performed. Values of p<0.05 were considered significant. Results In 2018, there were 525 vaginal births, 27.8% of which were attended by obstetricians, 70.7% by obstetric nurses, and 1.5% evolved without assistance. Overall, 55.2% of the parturients had some degree of laceration. The professional who attended the birth was a significant variable: a greater number of first- and second-degree lacerations, as well as more severe cases, occurred in births attended by nurses (odds ratio [OR]: 2,95; 95% confidence interval [95%CI]: 1,74 to 5,03). Positions at birth that did not enable perineal protection techniques (expulsive period with the "hands-off" method), when analyzed in isolation, determined the risk; however, in the final regression model, this relationship was not confirmed. Although reported in the literature, there were no associations between the occurrence of laceration and age, skin color, or birth weight. In 24% of the births, episiotomy was performed, and doctors performed 63.5% of them. Conclusion Births attended by nurses resulted in an increased risk of perineal lacerations, of varying degrees. In turn, those assisted by physicians had a higher occurrence of episiotomy.

Resumo Objetivo Aproximadamente 85% dos partos vaginais cursam ou com lacerações perineais e/ou com episiotomia. Este estudo objetivou determinar a incidência de lacerações e episiotomias das parturientes de 2018 de uma maternidade pública de risco habitual, no sul do Brasil, bem como determinar os fatores de risco e proteção para tais eventos. Métodos Estudo transversal retrospectivo, no qual os dados foram obtidos dos prontuários e analisados no programa Stata. Realizaram-se regressões logísticas uni e multivariada. Foram considerados como significantes valores de p<0,05. Resultados Em 2018, aconteceram 525 partos vaginais, sendo 27,8% assistidos por médicos obstetras, 70,7%, por enfermeiros obstetras, e 1,5% evoluíram sem assistência. Ao todo, 55,2% das parturientes apresentaram algum grau de laceração. O profissional que assistiu ao parto foi uma variável que demonstrou significância: um maior número de lacerações de primeiro e segundo graus, bem como casos de maior gravidade, ocorreram em partos assistidos por enfermeiros (razão de probabilidades [RP]: 2,95; intervalo de confiança de 95% [IC 95%]: 1,74 a 5,03). Posições ao nascimento que não permitiam técnicas de proteção perineal (período expulsivo na técnica "sem mãos" [hands off, em inglês]), quando analisadas isoladamente, determinaram o risco; contudo, no modelo final de regressão, essa relação não se confirmou. Apesar de relatada na literatura, não houve associação entre a ocorrência de laceração e a idade, a cor da pele, ou o peso de nascimento. Em 24% dos partos, uma episiotomia foi realizada, tendo os médicos executado 63,5% delas. Conclusão Partos assistidos por enfermeiros resultaram em um maior risco de lacerações perineais, de variados graus. Por sua vez, os assistidos por médicos apresentaram maior ocorrência de episiotomia.

Application effects of unprotected perineal delivery technique in low-risk nulliparous women during natural delivery / 中国基层医药

Objective:To investigate the application effects of unprotected perineal delivery technique in low-risk nulliparous women during natural delivery.Methods:Seventy low-risk nulliparous women who delivered in January to December 2017 in Huaibei People's Hospital were included in this study. They were randomly assigned to undergo delivery with either conventional technology (control group, n = 35) or unprotected perineal delivery technique (observation group, n = 35). Lateral episiotomy rate, incidence of perineal tears, labor process time and Visual Analogue Scale score as well as the degree of postpartum perineal pain were compared between two groups. Results:Lateral episiotomy rate in the observation group was significantly lower than that in the control group [8.57% (3/35) vs. (45.71% (16/35), χ2 = 10.402, P < 0.001). The incidence rates of complete perineum, grade I perineal injury and grade II perineal injury in the observation group were 34.29% (12/35), 57.14% (20/35) and 8.57% (3/35), respectively, and those in the control group were 11.43% (4/35), 28.57% (10/35) and 60.00% (21/35) respectively ( χ2 = 4.732, 4.725, 18.324, all P < 0.05). The Visual Analogue Scale score in the observation group was significantly lower than that in the control group [(3.08 ± 0.42) points vs. (5.13 ± 0.58) points, t = 16.936, P < 0.001]. There were no significant differences in the time of first-stage, second-stage and third-stage labors between the two groups (all P > 0.05). Conclusion:Application of unprotected perineal delivery technique for low-risk primipara delivery can reduce maternal injury during delivery, which is worthy of application.

El hallazgo principal al establecer el diagnóstico: en 20 una tumoración, 15 de 20 eritema y 11 mastalgia. El reporte radiológico mediante BIRADS fue de IVA en 12, IVB en 6 y 1 tanto para II y III. En todas las pacientes se comprobó el diagnóstico con estudio histopatológico. Doce recibieron tratamiento inicial con prednisona, 7 con antibióticos y AINES y un caso con escisión quirúrgica. CONCLUSIONES: La mastitis granulomatosa idiopática es una enfermedad rara de prevalencia aún desconocida, con un comportamiento benigno de tipo inflamatorio crónico, cuya patogenia permanece aún desconocida. Al ser una enfermedad con un diagnóstico por exclusión, obliga al estudio histopatológico para establecer el diagnóstico definitivo, idealmente mediante la toma de una biopsia con Tru-cut. Aunque se han planteado varias alternativas terapéuticas, en la actualidad no existe un protocolo universal que justifique un tratamiento en forma generalizada. La resección de la lesión con márgenes amplios asociada o no con corticoides orales, sigue siendo el tratamiento más indicado.

Abstract: OBJECTIVE: To perform a demographic, clinical and imaging characterization of a series of cases of idiopathic granulomatous mastitis. MATERIALS AND METHODS: Observational, retrospective and cross-sectional study of a series of cases of patients diagnosed with idiopathic granulomatous mastitis, at Hospital Universitario "Dr. José Eleuterio González in Monterrey, Mexico between January 2015 and December 2019. The study comprised all patients older than 18 years old who had histological diagnosis of idiopathic granulomatous mastitis in the absence of a specific agent. Patients with mastitis related to a specific pathology or with a history of recent breast trauma/laceration were excluded. Variables to determine are demographic information (age, education, marital status, etc.), diagnostic process/method, imaging findings and treatment. RESULTS: 20 patients with an average age of 32 years were included, 17 of childbearing age, and the rest at menopause. All patients had at least one full-term pregnancy and a variable lactation period. 19 presented the disease unilaterally, 60% in the left breast. Clinical presentation: 20 presented tumor, 15 erythema and 11 mastalgia. Imaging: BIRADS IVA in 12, IVB in 6 , III in 1 and II in 1. Diagnostic confirmation was performed in all patients by histopathological study. 12 received initial treatment with prednisone, 7 with antibiotics and NSAIDs, and one case with surgical excision. CONCLUSIONS: Idiopathic granulomatous mastitis is a rare benign and chronic inflammatory disease of unknown prevalence and pathogenesis. It mainly affects women of reproductive age. Imaging studies usually report nonspecific findings. It requires histopathological study to establish a definitive diagnosis, as it is a disease with diagnosis by exclusion, ideally by taking a Tru-cut biopsy. Although several therapeutic alternatives have been proposed, currently there is no universal protocol for treatment, however, resection of the lesion with wide margins associated or not with oral corticosteroids prevails as the most widely used treatment nowadays.

Interpretation of 2018 American College of Obstetricians and Gynecologists Practice Bulletin: Prevention and management of obstetric lacerations at vaginal delivery / 中华围产医学杂志

Lacerations are common after vaginal birth.Although most obstetric lacerations ended with good outcomes,those severe ones are associated with increased risk of several short-and long-term problems,including pelvic floor injury,fecal or urinary incontinence,postpartum pain,and sexual dysfunction.The American College of Obstetricians and Gynecologists (ACOG) published a practice bulletin about the prevention and management of obstetric lacerations at vaginal delivery in 2018,providing an evidence-based comprehensive guideline for prevention,identification,and repair of obstetric lacerations and episiotomy.This article presented the essence of the guideline in order to improve the awareness of the new strategies of prevention and management of obstetric lacerations among gynecologists and obstetricians.

Clinical study of anal sphincter training combined with manual protection to reduce the risk of obstetric anal sphincter rupture / 中国实用护理杂志

Objective@#To investigate the effect of anal sphincter training combined with manual protection to reduce the risk of obstetric anal sphincter rupture.@*Methods@#Totally 720 primipara were randomly divided into two groups by random number table method, with 360 cases in each group. The control group was given manual protection during midwifery. The observation group was given anal sphincter training before delivery and manual protection during midwifery. Postpartum anal pressure (anal resting pressure, anal systolic pressure), rectal pressure (rectal resting pressure, rectal defecation pressure) were measured. The incidence of postpartum anal incontinence (gas incontinence, liquid fecal incontinence, and solid fecal incontinence), defecation (urgent defecation, anal pain during defecation, pushing rectal defecation, protrusion of anal canal after defecation) and rupture of anal sphincter were recorded.@*Results@#Postpartum rectal resting pressure and rectal defecation pressure were (4.50±0.44) and (65.41±10.66) mmHg (1 mmHg=0.133 kPa) in the observation group and (5.68±0.61) and (56.75±9.83) mmHg in the control group, respectively. There were significant differences between the two groups (t=6.011, 8.027, P<0.01). The incidence of postpartum gas incontinence, liquid fecal incontinence and solid fecal incontinence were 2.22% (8/360), 0.56% (2/360) and 0.56% (2/360) respectively in the control group and 0.56% (2/360) in the observation group. The incidence of postpartum gas incontinence, liquid fecal incontinence and solid fecal incontinence were 0.56% (2/360), 0.27% (1/360) and 0.27% (1/360), respectively. There were significant differences between the two groups (χ2=4.120, P<0.05). The incidences of postpartum urgency, anal pain, pushing and pressing rectal defecation and anal canal prolapse were 3.33% (12/360), 3.89% (14/360), 3.89% (14/360), 3.89% (14/360), 1.11% (4/360) in the control group and 1.67% (6/360), 2.22% (8/360), 1.67% (6/360) and 0.56% (2/360) in the observation group, respectively (χ2=5.101, P<0.01). The incidence of rupture of anal sphincter was 0.56% (2/360) in the observation group and 3.33% (12/360) in the control group. There was significant difference between the two groups (χ2=5.887, P<0.05).@*Conclusion@#Anterior anal sphincter training combined with manual protection during midwifery can effectively reduce the risk of anal sphincter rupture and protect the rectal and anal functions of pregnant women.

A comparison between the efficacy of human corneal lenticule with single blood donor fibrin glue versus sutures for sealing induced corneal penetrating wounds in porcine eyes

Objective@#To determine the efficacy of human corneal lenticule from small incision lenticule extraction (SMILE) with single blood donor fibrin glue as corneal patch for sealing induced corneal penetrating wounds in cadaveric porcine eyes compared to suturing using 2 simple interrupted nylon 10-0 sutures. @*Methodology@#This is an in vitro comparative experimental study using cadaveric porcine eyes. Twenty (20) porcine eyes were randomized into control and treatment groups. A 3-mm metal keratome was used to create a fullthickness incision with the keratome angled perpendicular to the central cornea. Seidel’s test was done to confirm leakage. An anterior chamber maintainer connected to the Centurion® Vision System (Alcon, USA) was inserted into a peripheral corneal incision with the infusion turned off. Induced corneal penetrating wounds were sealed by application of single blood donor fibrin glue and human corneal lenticule obtained from SMILE in the treatment group. In the control group, 2 simple interrupted nylon 10-0 sutures were used for wound closure. Intraocular pressure (IOP) was set at 30 mmHg using the Centurion® Vision System and IOP was increased by increments of 5 mmHg until leakage is documented. @*Results@#All porcine eyes in the control group showed no leakage immediately after sealing. One out of 10 eyes in the experimental group showed positive Seidel’s test after application of lenticule patch graft (odds ratio = 1.11 [0.904-1.336]). The mean leakage pressure for the suture group was significantly higher at 87.00 ± 4.83 mmHg compared to the lenticule group at 30.00 + 0.00 mmHg (p-value <0.001).@*Conclusion@#Human corneal lenticule from SMILE with single blood donor fibrin glue as cornel patch is less effective in sealing induced corneal penetrating wounds in cadaveric porcine eyes at IOP equal to or greater than 30 mmHg as compared to suturing using 2 simple interrupted nylon 10-0 sutures.
