Comportamiento clínico del parto vertical y en posición de litotomía en dos centros de salud de Cusco, Perú / Clinical behavior of vertical delivery and in lithotomy position in two Health Centers of Cusco, Peru

Resumen OBJETIVO: Comparar el comportamiento clínico del parto vertical con el horizontal en embarazadas atendidas en dos centros de salud de Cusco, Perú. MATERIALES Y MÉTODOS: Estudio descriptivo, comparativo y prospectivo con un componente correlacional efectuado en dos centros de salud de la ciudad de Cusco, Perú, del 1 de septiembre del 2020 al 31 de enero del 2021, en mujeres embarazadas que tuvieron parto vertical u horizontal. El cálculo del tamaño de muestra se estableció con el programa estadístico EPIDAT mediante la comparación de medias de grupos independientes. RESULTADOS: Se estudiaron 212 pacientes (106 en parto vertical y 106 en posición de litotomía). En las pacientes con parto horizontal se registraron 3 casos de activación de código rojo (1.42%) con sangrado máximo de 2500 cc. El grado de desgarro vaginal más frecuente fue 1, en 103 mujeres (48.58%). La involución uterina en los dos grupos, a las 6 h, fue de 13 cm en 80 mujeres (37.74%), a las 12 h de 12 cm en 83 mujeres (39.15%) y para las 24 h de 11 cm en 84 mujeres (39.62%). Las horas mínimas de trabajo de parto fueron 2.38 h en el grupo de parto vertical; el puntaje Apgar más bajo fue 7 al primer minuto (1.42%) y al minuto 5 (0.47%). CONCLUSIONES: El parto vertical puede ofrecer ventajas significativas en comparación con el horizontal en algunas variables: trabajo de parto más corto, Apgar al minuto e involución uterina. Para las demás variables estudiadas no se encontraron diferencias estadísticamente significativas.

Abstract OBJECTIVE: To compare the clinical behavior of vertical delivery and delivery in the lithotomy position in pregnant women attended in two health centers in Cusco, Peru. MATERIALS AND METHODS: Descriptive, comparative and prospective study with a correlational component carried out in two health centers in the city of Cusco, Peru, from September 1, 2020 to January 31, 2021 in pregnant women who delivered vertically or horizontally. The sample size was calculated using the EPIDAT statistical program by comparing the means of independent groups. RESULTS: 212 patients were studied (106 in vertical delivery and 106 in lithotomy position). In horizontal delivery patients there were 3 cases of code red activation (1.42%) with maximum bleeding of 2500 cc. The most frequent vaginal tear grade was 1, in 103 women (48.58%). Uterine involution in the two groups, at 6 h, was 13 cm in 80 women (37.74%), at 12 h 12 cm in 83 women (39.15%) and by 24 h 11 cm in 84 women (39.62%). Minimum labor hours were 2.38 h in the vertical delivery group; the lowest Apgar score was 7 at 1 min (1.42%) and at 5 min (0.47%). CONCLUSIONS: Vertical delivery may offer significant advantages compared to horizontal delivery in some variables: shorter labor, Apgar at minute and uterine involution. For the other variables studied, no statistically significant differences were found.

Epiphora drainage by DCR – Long-term results

Background: Dacryocystorhinostomy (DCR) refers to the surgical procedure that is used to relieve the chronic obstruction of the nasolacrimal duct obstruction (NLDO). In a maxillofacial setting, NLDO may arise subsequent to a facial trauma or orthognathic surgery. There is a dearth of literature from this part of the world. This article intends to provide a single maxillofacial center experience in DCR. Materials and Methods: This is a retrospective, noncomparative, noninterventional, record audit type of study of all consecutive patients fulfilling inclusion and exclusion criteria. All patients with epiphora and diagnosed with lacrimal apparatus damage between 1 January 2008 and 31 December 2017 requiring DCR were considered for the study. Details of demographics, phase of treatment (primary/retreatment), types of bones involved, age, complications, period suffering from epiphora, and follow-up were obtained. All data were entered and analyzed using the Statistical Package for the Social Service (version 16; IBM). Descriptive statistics of the frequency and mean ± standard deviation (SD) as appropriate were presented. Chi-square test and one-way analysis of variance were used appropriately. P ≤ 0.05 was taken to be statistically significant. Results: In all, 83 patients fulfilled the inclusion and exclusion criteria. It is more common in males (n = 56, 67.47%) with a mean ± SD of 32.24 ± 10.80 (18–59 years) with 27 (32.53%) of them presenting primarily after fractures. Fracture was the most common pathology seen in 81.93% (n = 68) of cases, while the rest were as a result of orthognathic cases. Le Fort II and III set of bones contributed to 59% of cases, while the orbitonasal complex contributed to only three cases. NLD obstruction was seen in 68 (81.9%) of cases. On an average, the patients suffered for 9.3 ± 6.74 months (range 0.5–22 months) before seeking treatment and the average follow-up was 31.07 ± 11.69 months (range 15–54 months). Discussion and Conclusion: Fractures and surgeries involving nasal bones carry an innate risk of damaging the NLD system. The pattern of need for DCR and occurrence of NLDO in this part of the world have been described. The extent of the anatomical variations and need for proper surgical planning are highlighted.

Secondary Short-Lasting Unilateral Neuralgiform Headache with Conjunctival Injection and Tearing: A New Case and a Literature Review

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis. However, there is increasing evidence in the literature for secondary SUNCT being attributable to certain known lesions. We explored the possible neurobiological mechanism underlying SUNCT based on all reported cases of secondary SUNCT for which detailed information is available. Here we report a case of neuromyelitis optica spectrum disorders that had typical symptoms of SUNCT that might have been attributable to involvement of the spinal nucleus of the trigeminal nerve. We also review cases of secondary SUNCT reported in the English-language literature and analyze them for demographic characteristics, clinical features, response to treatment, and imaging findings. The literature review shows that secondary SUNCT can derive from a neoplasm, vascular disease, trauma, infection, inflammation, or congenital malformation. The pons with involvement of the trigeminal root entry zone was the most commonly affected region for inducing secondary SUNCT. In conclusion, the neurobiology of secondary SUNCT includes structures such as the nucleus and the trigeminal nerve with its branches, suggesting that some cases of primary SUNCT have underlying mechanisms that are related to existing focal damage that cannot be visualized.

Dacryoscintigraphic Findings in the Children with Tearing

PURPOSE: To investigate the diagnostic effectiveness of dacryoscintigraphy in children with tearing; to evaluate tear clearance rate as a diagnostic factor of dacryoscintigraphy in children with tearing; and to analyze the results of treatment according to dacryoscintigraphic findings in children with tearing. METHODS: Between January 2010 and April 2014, 176 eyes of 88 children with tearing (49 boys and 39 girls; mean age, 23.81 ±14.67 months; range, 12 to 72 months) were studied retrospectively. Of these, 37 of 88 children with tearing were bilateral cases, and 51 were unilateral cases. None of the patients had a history of craniofacial disorder or trauma. The chief complaint of tearing with or without eye discharge and delivery mode, past history of neonatal conjunctivitis, syringing, or probing were collected from parents, grandparents, or previous hospital data. The drainage pattern of the nasolacrimal duct was analyzed, and the clearance rate of 50 microCi 99m technetium pertechnetate was measured by dacryoscintigraphy. RESULTS: According to the dacryoscintigraphy results, 98 of 125 eyes (78.4%) with tearing showed nasolacrimal obstruction and 29 of 51 eyes (56.9%) without tearing showed patency. There was a significant difference between tearing eyes and normal eyes (p = 0.001). The clearance rate difference after 3 and 30 minutes was 16.41 ± 15.37% in tearing eyes and 23.57 ±14.15% in normal eyes. There was a significant difference between epiphoric eyes and normal eyes (p = 0.05). Based on the dacryoscintigraphic findings, nasolacrimal-duct obstruction was treated with probing or silicone-tube intubation. The majority of patients showed symptom improvement (75.2%) during the two months of follow-up. CONCLUSIONS: Dacryoscintigraphy is a non-invasive method of qualitatively and quantitatively diagnosing nasolacrimal duct obstruction in children with tearing.

Diffuse Pneumocephalus : A Rare Complication of Spinal Surgery

The common etiologies of pneumocephalus, presence of air in the intracranial cavity, are trauma and cranial surgery. Pneumocephalus after spinal surgery is an unusual postoperative complication. We report the case of a male 59-year-old man who developed a pneumacephalus after posterior lumbar surgery for spinal stenosis. Intraoperatively, a cerebrospinal fluid leak following a dural tear was noted and immediately repaired. The next day, the patient complained of headache and dizziness. Head and lumbar computed tomography scans revealed significant air in the frontal region, several cisterns, intraventricle, and extra-dural area in the spine canal. Symptoms were spontaneously resolved within 2 weeks with conservative management.

Abducens Nerve Palsy after Lumbar Spinal Fusion Surgery with Inadvertent Dural Tearing

Abducens nerve palsy associated with spinal surgery is extremely rare. We report an extremely rare case of abducens nerve palsy after lumbar spinal fusion surgery with inadvertent dural tearing, which resolved spontaneously and completely. A 61-year-old previous healthy man presented with chronic lower back pain of 6 weeks duration and 2 weeks history of bilateral leg pain. He was diagnosed as having isthmic spondylolisthesis at L4-5 and L5-S1, and posterior lumbar interbody fusion was conducted on L4-5 and L5-S1. During the operation, inadvertent dural tearing occurred, which was repaired with a watertight dural closure. The patient recovered uneventfully from general anesthesia and his visual analogue pain scores decreased from 9 pre-op to 3 immediately after his operation. However, on day 2 he developed headache and nausea, which were severe when he was upright, but alleviated when supine. This led us to consider the possibility of cerebrospinal fluid leakage, and thus, he was restricted to bed. After an interval of bed rest, the severe headache disappeared, but four days after surgery he experienced diplopia during right gaze, which was caused by right-side palsy of the abducens nerve. Under conservative treatment, the diplopia gradually disappeared and was completely resolved at 5 weeks post-op.

Función social de las lágrimas: una indagación empírica sobre los tipos de llanto emocional / Social function of tears: an empirical inquiry about the types of emotional tearing

El intercambio emocional humano implica expresión/reconocimiento de emociones. La cara es el lugar privilegiado para expresar o leer la emoción. Algunas emociones se asocian con llanto emocional, diferenciable del basal y del reflejo. Murube, Murube y Murube (1999) clasificaron el llanto emocional en de demanda y de ofrecimiento de ayuda. Se evaluó la validez de dicha tipología empleando rostros humanos de ambos sexos que lloraban por dolor propio y ajeno. Un grupo de jueces clasificó el llanto expresado en esos rostros. Se calcularon tasas de acierto de discriminación de llanto y se realizaron pruebas chi-cuadro por sexo. Los resultados no apoyan la idea de una habilidad para distinguir dos tipos de llanto y son explicados desde un punto de vista cultural.

Human emotional interchange implicates expression/recognition of emotions. The human face is a conspicuous place to express/read emotion. Certain emotions associate with emotional tearing, differentiable from basal and reflex tearing. Murube, Murube and Murube (1999) classified emotional tearing in requesting- and offering -help. The validity of that typology was evaluated using faces of people of both sexes crying because of their own suffering and because of other’s suffering. A group of judges classified the crying shown by those faces. Discrimination hit rates andqui-square tests were estimated by sex. Results do not support a human ability to distinguish two types of crying andare interpreted from a cultural point of view.

A reappraisal of the capsulorhexis:tearing angle in capsulorhexis / 国际眼科杂志(Guoji Yanke Zazhi)

ATM:To determine the tearing angle and tearing force,and effects of associated pressures in tearing of various materials and human lens capsule in continuous curvilinear capsulorhexis(CCC).METHODS:Tearing was done on different materials such as aluminum Iaminated paper,different types of thin transplant plastics and human Iens capsule with blunt tip needle.During the procedure,angle and direction of force were measured.Effects of increased underlying pressure on tearing of tearable materials and effect of anterior chamber depth and vitreous pressure on 24 postmortem hunlan eyes with different ages (range from10 to 75 years),was evaluated.RESULTS:Tearing angle in every material was unique for that material.Angle and force of tearing was decreased reversely with increasing age (from 85 degree in a 10-years-old to 10 degree in older than 50 years).Increasing vitreous pressure and decrease in AC depth causes higher pressure on point of tearing.Safe methods in controlling CCC are discussed jn the context.OONCLUSION:Understanding the physics and vector of forces during CCC is necessary in good performance and avoidance of radial tears.Onange in capsular properties between difierent ages and different type of cataract causes different tearing angle and tearing force that should be considered during CCC.

Surgery of the tearing (lacrymation) problem by dacryocystorhinostomy

When properly chosen, cases of tearing from chronic dacrycystitis could be helped by this anastomising procedure (DCR) with a relative guarantee of success provided a big bony window is made with sac extirpation in addition to the flap. The procedure is not a highly technical one. In the absence of an Illiff trephine which is suitable for this operation, a good size bony window can still be made with the use of a 3/8 curve gauge and rongeour. Patients cooperation is very important and we use to tell them that the operation is very insignificant compared to the follow up which may spell the success or failure of the operation. (Conclusion)
