En la comunidad internacional desde hace algunos años se hace referencia a los denominados “derechos sexuales y reproductivos”, los cuales, inicialmente ligados de modo inocuo a la salud y a la paternidad responsable, son luego tendenciosamente combinados con la perspectiva del género, evidenciando afectaciones a la vida humana (con la promoción del aborto), al matrimonio y a la familia. Un análisis de sus presupuestos y expresiones actuales son presentados escuetamente en este trabajo.
La intervención de terceros en el proceso civil: El interés como criterio delimitador de la calidad de tercero.
Authors: Vilela Chinchay Sheila María 
Published: December 2020

Los terceros en el proceso civil constituyen una categoría que no ha resultado fácil de comprender. Existen dos concepciones de tercero que interesa anotar para analizar la intervención de terceros regulada en el C.P.C. Una vinculada al hecho de ser ajeno al proceso (sentido amplio) y otra vinculada a la ruptura del principio de dualidad del proceso (sentido estricto). Habrá quienes al intervenir en el proceso se conviertan en parte y como tal no es admisible su regulación dentro del acápite de la intervención de terceros, y habrá quienes al ingresar al proceso triangulen este y en consecuencia se constituyan en verdaderos terceros. Será determinante para identificar esta última categoría el tipo de interés con el que se solicita tutela al órgano jurisdiccional.

Published: December 2020

Предотвращение несанкционированного проникновения легководолазов в прибрежные мелководные акватории остается актуальной задачей. Для диапазона частот ниже 100 Гц, характерного для шумов, связанных с дыханием водолаза-аквалангиста, существенная часть регистрируемых размещенными у дна гидрофонами может быть соотнесена с сейсмоакустической составляющей волны, бегущей по осадочному чехлу дна и/или тонкому придонному водному слою акватории. Дистанции, на которых удается идентифицировать низкочастотные дыхательные шумы водолаза-аквалангиста, достигают 180–220 м.
Prevention of scuba-diver trespassing shallow-water littoral areas is considered as actual. In frequency range below 100 Hz, characteristic for respiratory- associated noise of scuba-divers, a significant part of the signal registered with bottom-mounted hydrophones, may be connected to the seismoacoustic component of the wave, travelling through the sedimentary bed and/or through a thin water
layer above it. An identification of low-frequency respiratory-associated noises of scuba-diver in shallow-water areas is achieved at distances up to 180–220 м.

Проанализированы проблемы создания приемников градиента давления различных типов для использования в низкочастотном диапазоне, определяемые необходимостью достижения достаточной чувствительности к звуковому давлению в плоской волне, коэффициента деления дипольной характеристики направленности не хуже 26 дБ, динамического диапазона не менее 80–100 дБ. Теоретически оценены пределы применимости ПГД 2-гидрофонного (разностного) типов по волновым размерам. Разработаны высоко- эффективные ПГД инерционного и силового типов. Предложено комбинирование ПГД инерционного/силового и 2-гидрофонного типов в линейной антенне.
The problems of development of pressure gradient sensors of various types for usage in low-frequency range are analyzed, which are connected to a necessity to provide acceptable sensitivity to sound pressure in a flat wave, minima of the dipole directivity pattern being nor less 26 dB, dynamic range being nor less
80–100 dB. The wavelength limits of acceptability of 2-hydrophone (differential) pressure gradient sensors are theoretically predicted. High effective pressure gradient sensors of inertial and force types are designed. It is suggested to combine a pressure gradient sensor of inertial or force type with the pressure gradient sensor of 2-hydrophone type in linear array.

Published: December 2020

Background: Ovarian torsion diagnosis is a great challenge as delay in diagnosis can cause severe morbidity. Early accurate diagnosis is crucial to preserve ovarian function. Ultrasonography being the primary imaging modality plays a vital role in the evaluation of suspected ovarian torsion by helping surgeons reach the correct diagnosis, thus avoiding unnecessary intervention. This study aims to determine the diagnostic accuracy of isolated and combined sonographic features of ovarian torsion on grey scale and Doppler transvaginal ultrasonography.
Patients and methods: From radiology database, from January 2016 till December 2019, sonographic signs of ovarian torsion in 113 women with suspected ovarian torsion on ultrasonography and subsequent surgical diagnosis were evaluated. Ultrasound findings were compared with surgical findings to determine the accuracy, sensitivity, specificity, and positive and negative predictive values of individual and combined ultrasound signs.
Results: Diagnostic accuracy of ultrasound for ovarian torsion was 85.8%. Abnormal ovarian Doppler flow was the most accurate individual sonographic sign with accuracy, sensitivity, specificity and positive predictive value of 85.8%, 83.5%, 100% and 100% respectively followed by ovarian enlargement and ovarian edema. Combined ultrasound signs resulted in higher sensitivity and positive predictive values, and lower specificity and negative predictive values for ovarian torsion. Increasing the number of sonographic parameters increased the specificity but decreased sensitivity. High accuracy, sensitivity, positive predictive value, specificity and negative predictive value was seen when combination of three or two sonographic parameters was used as diagnostic criteria.
Conclusion: Transvaginal sonography is a convenient, reliable and extremely useful imaging modality for preoperative diagnosis of ovarian torsion with high specificity, sensitivity, positive predictive value and diagnostic accuracy helping treating physicians to take prompt decisions regarding timely surgical intervention. However, due to low negative predictive values, absence of sonographic signs does not rule out ovarian torsion and high index of clinical suspicion remains of utmost importance.

Authors: Ahmad Majid Rauf , Javed Iffat , Mushtaq Suhaila 
Published: December 2020

Background: Dermatophytoses infections are widespread in the developing world. The laboratory diagnosis of dermatophytes has been a challenge as it involves microscopy and trained personnel. Potassium hydroxide wet mount with dimethyl sulfoxide added is routinely used in direct microscopy. But it lacks color contrast and the hyphae may be missed on routine microscopy. The study aimed to evaluate the effectiveness of the Chicago sky blue stain against routine potassium hydroxide-dimethyl sulfoxide (KOH/DMSO) wet mount in direct microscopy.
Patients and methods: The study was carried out at the Department of Microbiology, Postgraduate Medical Institute, Lahore over a period of nine months from July 2013 till March 2014. Patients of either gender regardless of age, clinically diagnosed as having dermatophytoses by dermatologists were selected for this study. Specimens from 100 patients were collected from the dermatology outdoor of a tertiary care hospital for this study. They were evaluated microscopically with routine potassium hydroxide-dimethyl sulfoxide (KOH-DMSO) wet mount and Chicago sky blue (CSB) stain. Data were collected and entered in Statistical Package for the Social Sciences (SPSS) version 20.0.
Results: Out of a total of 100 samples collected from skin, hair and nails, 59% were positive on direct microscopy with KOH/DMSO wet mount. Whereas direct microscopy using CSB stain revealed dermatophytes in 62% of cases.
Conclusion: Chicago sky blue staining is a better technique for the detection of dermatophytes as compared to potassium hydroxide wet mount examination. It is simple, rapid, and easy to interpret. We recommend the use of this technique to improve the detection of dermatophytes without awaiting the results of the culture.

Published: December 2020

Background: Central serous chorioretinopathy (CSCR) is an idiopathic disorder in which there is leakage of fluid from hyper permeable choriocapillaris and the collection of fluid between neurosensory and neuropigmentry retina in the macular area that is responsible for decrease visual acuity. CSCR may be acute or chronic. Various treatment options include simple observation, argon laser photocoagulation of the leaking spot, photodynamic therapy (PDT), oral ketoconazole and oral rifampicin are available. Ranibizumab is a monoclonal antibody fragment that act as vascular endothelial growth factor inhibitor, stabilize blood retinal barrier and decrease leakage from choriocapillaris. This study aims to evaluate the role of intravitreal ranibizumab for rapid recovery in central serous chorioretinopathy.
Patients and methods: This descriptive case series was carried out at Department of Ophthalmology, Nishtar Medical University Multan, Pakistan from 01-10-2019 till 30-04-2020. The study included twelve eyes of twelve patients suffering from acute CSCR. All patients were given a single injection of intravitreal ranibizumab (0.5mg/0.05ml) as a primary treatment and followed for two months after injection at one week, one month and two months interval to document efficacy of intravitreal ranibizumab. At each baseline and follow up visits, dilated fundus examination was carried out, ending up with patients’ best corrected visual acuity. Central retinal thickness (CRT) was also recorded and results were compared with prior visit results of patients. Major outcomes were the improvement in visual acuity and decrease in CRT. Baseline CRT values were also compared with post injection CRT values at one week, one month and two months intervals using paired sample t-test and best corrected visual acuity (BCVA) was compared using chi–square test.
Results: Mean age of the patients was 39.6 years with a male to female ratio of 9:1. Best corrected visual acuity was 6/60 on Snellen chart at baseline. All patients exhibited mean improvement of best corrected visual acuity of three Snellen lines after one week. Eleven patients were back to best corrected visual acuity of 6/6 after one month. Remaining one patient gained best corrected visual acuity of 6/6 after two months of post injection. The mean CRT at presentation was 500 ± 80U (range; 386–580) which reduced significantly to 272 ± 52 U (range 220–338) from baseline after one month showing significant reduction (p<0.001). At the last follow-up visit, the CRT was measured 230 ± 20 U (range 220—250) which shows complete resolution of sub-retinal fluid.
Conclusion: Intravitreal ranibizumab can be used for rapid absorption of sub-retinal fluid in acute CSCR and significant reduction in CRT along with improvement in BCVA indicate that it may be safely employed in CSCR to achieve better clinical outcomes.

Published: December 2020

An overlap-free (or $\beta$-free) word $w$ over a fixed alphabet $\Sigma$ is extremal if every word obtained from $w$ by inserting a single letter from $\Sigma$ at any position contains an overlap (or a factor of exponent at least $\beta$, respectively). We find all lengths which admit an extremal overlap-free binary word. For every "extended" real number $\beta$ such that $2^+\leqslant\beta\leqslant 8/3$, we show that there are arbitrarily long extremal $\beta$-free binary words.

Personnel’s preferred ways of workplace learningThe aim of the study is to analyze different ways of workplace learning, particularly the connec tions between workplace learning and one’s gender, age and organizational hierarchy position. The survey conducted among the Finnish water utilities’ personnel (N = 412) draws on three metaphors of learning, namely acquisition, participation and knowledge-creation. According to the results, knowledge acquisition and knowledge creation are predicted by organizational hierarchy position and learning by participation is predicted by gender and age. The results give an idea what kind of ways of learning and learning environments could be designed in workplaces when taking into account the needs and preferences of employees in different organizational positions.
