Authors: Del Castillo Rodríguez Ángel
Published: April 2023

El perfil de estudiantado universitario ha cambiado a lo largo de los últimos años. El uso de Internet y las redes sociales ha propiciado la inmediatez en el día a día. A ello se suma que en los últimos años se ha incrementado el número de estudiantes conocidos como “sisis”, esto es, estudiantes que estudian y trabajan al mismo tiempo. A este perfil de estudiante ya no solo le basta con una clase magistral, sino que, dado el esfuerzo que realizan para poder formarse -de forma presencial u online (e-learning)- debemos, al menos, tener en cuenta distintas técnicas o herramientas que pueden ayudar a fomentar la participación, motivar al alumnado y facilitar la adquisición y asimilación del conocimiento expuesto en las sesiones formativas. En esta línea, presentamos un teaching case en el cual se utilizaron herramientas de gamificación aplicables a la educación con el fin de reportar una experiencia que haga valorar y tener como referencia el uso de este tipo de programas o de técnicas a la hora de impartir formación en un contexto de enseñanza superior tanto en el entorno presencial como en el entorno online.-----------------------------------------------------------------------The profile of university students has changed in recent years.

Assessment of spectral UV radiation at Marambio Base, Antarctic Peninsula
Authors: Čížková Klára , Láska Kamil , Metelka Ladislav , Staněk Martin
Published: April 2023

Abstract. This study aims to assess the dependence of spectral UV
radiation on different atmospheric and terrestrial factors, including solar
zenith angle, ozone, and cloud cover, in the southern polar environment. For
this purpose, 23 260 spectra (300–363 nm), obtained by the B199 Mk-III
Brewer spectrophotometer at Marambio Base, Antarctic Peninsula region, over
the period 2010–2020, were studied. A neural network model was developed to
investigate the effects of the explanatory variables at 127 wavelengths in
the interval 300–363 nm, with a 0.5 nm sampling interval. Solar zenith
angle (SZA) proved to be the most important parameter, followed by cloud
cover, total ozone column (TOC), and surface albedo. The relative SZA effect
is greatest at the shortest wavelengths, where a 1∘ decrease in
SZA results in a 6 %–18 % increase in UV irradiance (305 nm). TOC
particularly affects the short wavelengths below approximately 320–325 nm, when for
example at 305 nm a 10 DU decrease in TOC causes a 7 %–13 % increase in
UV irradiance. The large-scale ozone holes (e.g., in 2011–2012, 2014–2015,
2018–2019) caused the spectral UV irradiance at very short wavelengths to peak
in spring, whereas in other seasons (e.g., 2010–2011, 2012–2013), the
maxima at all wavelengths were recorded in summer (November to January).
Absorption of UV radiance by the ozone also affected the temporal distribution
of very high spectral UV irradiances (i.e., highest 10 % of the
distribution), when at 305 nm they were observed both in spring and summer
months, and at 340 nm they occurred mostly in summer. The effect of cloud
cover was strongest near the fully cloudy sky and in the summer months, when
the Antarctic clouds tend to be thickest.

Abstract. Multiphase chemistry is an important pathway for the formation of secondary organic aerosols in the atmosphere. In this study, an indoor 2 m3 Teflon chamber system (Aerosol multIphase chemistry Research chamber, AIR) was developed and characterized to specifically simulate atmospheric multiphase chemistry processes. The temperature and humidity controls, diurnal variation simulation, and seed particle generation unit in this chamber system were designed to meet the needs of simulating multiphase atmospheric chemical reactions. The AIR chamber is able to accurately control temperature (2.5 ~ 31 ± 0.15 ℃) and relative humidity (RH < 2 % ~ > 95 % ± 0.75 %) over a relatively broad range. In addition, an RH regulation module inside the chamber was designed to simulate the diurnal variation of ambient atmospheric RH. The aerosol generation unit is able to generate pre-deliquescent seed particles with an organic-coating across a wide range of phase states or morphologies. The organic coating thickness of the aerosols within the chamber can be precisely controlled through adjusting the condensation temperature, further helping to elucidate the roles of seed particles in multiphase chemical reactions. The inner walls of the AIR chamber are passivated to reduce the wall loss rates of reactive gases. Yield experiments of α-pinene ozonolysis with and without seed particles combined with a box model simulation demonstrate the high-quality performance of secondary aerosol formation simulation using the AIR chamber.
Southern Weddell Sea surface freshwater flux modulated by icescape and atmospheric forcing

Published: April 2023

Abstract. Sea-ice formation dominates surface salt forcing in the southern Weddell Sea. Brine rejected in the process of sea-ice production results in the production of High Salinity Shelf Water (HSSW) that feeds the global overturning circulation and fuels the basal melt of the adjacent ice shelf. The strongest sea-ice production rates are found in coastal polynyas, where steady offshore winds promote divergent ice movement during the freezing season. The position of fast-ice areas and the presence of grounded icebergs (icescape) can influence the formation of polynyas and therefore impact sea-ice production. We use the Finite Element Sea ice–ice shelf–Ocean Model (FESOM) forced by output from the regional atmospheric model COSMO-CLM (CCLM) with 14 km horizontal resolution to investigate the role of polynyas for the surface freshwater flux of the southern Weddell Sea (2002–2017). The representation of the icescape in our model is included by prescribing the position, shape, and temporal evolution of a largely immobile ice mélange that was forming between the Filchner-Ronne Ice Shelf (FRIS) and a major grounded iceberg, as determined from MODIS satellite data on a monthly basis. We find that 70 % of the ice produced on the continental shelf of the southern Weddell Sea is exported from the region. While coastal polynyas cover 2 % of the continental shelf area, sea-ice production within the coastal polynyas accounts for 17 % of the overall annual sea-ice production (1509 km3). The largest contributions come from the Ronne Ice Shelf and Brunt Ice Shelf polynyas, and polynyas associated with the ice mélange. Furthermore, we investigate the sensitivity of the polynya-based ice production to the i) treatment of the icescape and ii) regional atmospheric forcing. Although large-scale atmospheric fields determine the sea-ice production outside polynyas, both the treatment of the icescape and the regional atmospheric forcing are important for the regional patterns of sea-ice production in polynyas. The representation of the ice mélange is crucial for the simulation of polynyas westward/eastward of it, which are otherwise suppressed/overestimated. Compared to using ERA-Interim reanalysis as an atmospheric forcing dataset, using CCLM output reduces polynya-based ice production over the eastern continental shelf due to weaker offshore winds and yields an overall more realistic polynya representation. Our results further indicate that the location and not just the strength of the sea-ice production in polynyas is a relevant parameter in setting the properties of the HSSW produced on the continental shelf, which in turn affects the basal melting of the Filchner-Ronne Ice Shelf.

Published: April 2023

Abstract. Accurate simulations of snow emission in surface-sensitive microwave channels are needed to separate snow from atmospheric information essential for numerical weather prediction. Measurements from a field campaign in Trail Valley Creek, Inuvik, Canada during March 2018 were used to evaluate the Snow Microwave Radiative Transfer (SMRT) Model at 89 GHz and, for the first time, frequencies between 118 and 243 GHz. In situ data from 29 snow pits, including snow specific surface area, were used to calculate exponential correlation lengths to represent the snow microstructure and to initialize snowpacks for simulation with SMRT. Measured variability in snowpack properties was used to estimate uncertainty in the simulations. SMRT was coupled with the Atmospheric Radiative Transfer Simulator to account for the directionally-dependent emission and attenuation of radiation by the atmosphere. This is a major developmental step needed for top-of-atmosphere simulations of microwave brightness temperature at atmosphere-sensitive frequencies with SMRT. Nadir simulated brightness temperatures at 89, 118, 157, 183 and 243 GHz were compared with airborne measurements and with ground-based measurements at 89 GHz. Inclusion of an anisotropic atmosphere in SMRT had the greatest impact on brightness temperature simulations at 183 GHz and the least at 89 GHz. Simulations compared well with observations, with a root mean squared error of 14 K, although snowpit measurements did not capture the observed variability fully as simulations and airborne observations formed statistically different distributions. Topographical differences in simulated brightness temperature between sloped, valley and plateau areas diminished with increasing frequency as the penetration depth within the snow decreased and less emission from the underlying ground contributed to the airborne observations. Observed brightness temperature differences between flights were attributed to the deposition of a thin layer of very low density snow. This illustrates the need to account for both temporal and spatial variability in surface snow microstructure at these frequencies. Sensitivity to snow properties and the ability to reflect changes in observed brightness temperature across the frequency range for different landscapes, as demonstrated by SMRT, is a necessary condition for inclusion of atmospheric measurements at surface-sensitive frequencies in numerical weather prediction.
The modelled climatic response to the 18.6-year lunar nodal cycle and its role in decadal temperature trends
Authors: Joshi Manoj , Hall Robert A. , Stevens David P. , Hawkins Ed
Published: April 2023

Abstract. The 18.6-year lunar nodal cycle arises from variations in the angle of the Moon's orbital plane. Previous work has linked the nodal cycle to climate but has been limited by either the length of observations analysed or geographical regions considered in model simulations of the pre-industrial period. Here we examine the global effect of the lunar nodal cycle in multi-centennial climate model simulations of the pre-industrial period. We find cyclic signals in global and regional surface air temperature (with amplitudes of around 0.1 K) and in ocean heat uptake and ocean heat content. The timing of anomalies of global surface air temperature and heat uptake is consistent with the so-called slowdown in global warming in the first decade of the 21st century. The lunar nodal cycle causes variations in mean sea level pressure exceeding 0.5 hPa in the Nordic Seas region, thus affecting the North Atlantic Oscillation during boreal winter. Our results suggest that the contribution of the lunar nodal cycle to global temperature should be negative in the mid-2020s before becoming positive again in the early 2030s, reducing the uncertainty in time at which projected global temperature reaches 1.5 ∘C above pre-industrial levels.
Weekly high-resolution multi-spectral and thermal uncrewed-aerial-system mapping of an alpine catchment during summer snowmelt, Niwot Ridge, Colorado
Authors: Wigmore Oliver , Molotch Noah P.
Published: April 2023

Abstract. Alpine ecosystems are experiencing rapid change as a result of warming temperatures and changes in the quantity, timing and phase of precipitation. This in turn impacts patterns and processes of ecohydrologic connectivity,
vegetation productivity and water provision to downstream regions. The fine-scale heterogeneous nature of these environments makes them challenging
areas to measure with traditional instrumentation and spatiotemporally coarse satellite imagery. This paper describes the data collection,
processing, accuracy assessment and availability of a series of approximately weekly-interval uncrewed-aerial-system (UAS) surveys flown over the Niwot Ridge Long Term Ecological Research site during the 2017 summer-snowmelt season. Visible, near-infrared and thermal-infrared imagery was collected. This unique series of 5–25 cm resolution multi-spectral and thermal orthomosaics provides a unique snapshot of seasonal transitions in a high alpine catchment. Weekly radiometrically calibrated normalised
difference vegetation index maps can be used to track vegetation health at the pixel scale through time. Thermal imagery can be used to map the
movement of snowmelt across and within the near sub-surface as well as identify locations where groundwater is discharging to the surface. A 10 cm resolution digital surface model and dense point cloud (146 points m−2) are also provided
for topographic analysis of the snow-free surface. These datasets augment ongoing data collection within this heavily studied and important
alpine site; they are made publicly available to facilitate wider use by the research community. Datasets and related metadata can be accessed through the Environmental Data Initiative Data Portal, https://doi.org/10.6073/pasta/dadd5c2e4a65c781c2371643f7ff9dc4 (Wigmore, 2022a), https://doi.org/10.6073/pasta/073a5a67ddba08ba3a24fe85c5154da7 (Wigmore, 2022c), https://doi.org/10.6073/pasta/a4f57c82ad274aa2640e0a79649290ca

The sea level time series of Trieste, Molo Sartorio, Italy (1869–2021)
Authors: Raicich Fabio
Published: April 2023

Abstract. The sea level observations carried out at Trieste, Molo
Sartorio, from 1869 to 2021 have been revised and updated. Information on the tide gauges and on the geodetic benchmarks on Molo Sartorio during that
period have been collected. Basic quality checks have been applied. The
hourly data for the 1917–1938 period, digitized from the original charts, have allowed us to build a time series of hourly sea level heights from 1905 to 2021. Gaps of up to 24 h have been filled by interpolation. The errors affecting the monthly and annual mean sea levels have been estimated. The
availability of monthly and annual means prior to 1904 allowed us to build a mean sea level time series spanning 153 years, characterized by linear trends of an observed sea level of 1.36 ± 0.17 mm yr−1 and of
an inverse-barometer-corrected sea level of 1.45 ± 0.13 mm yr−1. A significant acceleration of 0.008 ± 0.004 mm yr−2 was estimated
from the inverse-barometer-corrected sea level time series. This data set
represents the most up-to-date data set of sea level observations and
ancillary information relative to the tide-gauge station of Trieste, Molo
Sartorio. The data are available through SEANOE (https://doi.org/10.17882/62758, Raicich, 2022).
Auroral alert version 1.0: two-step automatic detection of sudden aurora intensification from all-sky JPEG images
Authors: Yamauchi Masatoshi , Brändström Urban
Published: April 2023

Abstract. A sudden and significant intensification of the auroral arc with expanding motion (we call it “local-arc breaking” hereafter) is an important event in many aspects but easy to miss for real-time watching due to its short rise time. To ease this problem, a real-time alert system for local-arc breaking was developed for the Kiruna all-sky camera (ASC) using ASC images in the JPEG format. The identification of the local-arc breaking is made in two steps using the “expert system” in both steps: (1) explicit criteria for classification of each pixel and simple calculations afterward are applied to each ASC image to obtain a simple set of numbers, or the “ASC auroral index”, representing the occupancy of aurora pixels and characteristic intensity of the brightest aurora in the image; (2) using this ASC auroral index, the level of auroral activity is estimated, aiming for Level 6 as clear local-arc breaking and Level 4 as a precursor for it (reserving Levels 1–3 for less active aurora and Level 5 for less intense sudden intensification). The first step is further divided into two stages. Stage (1a) uses simple criteria for R (red), G (green), and B (blue) values in the RGB color code and the H (hue) value calculated from these RGB values, each pixel of a JPEG image is classified into three aurora categories (from brightest to faintest, “strong aurora”, “green arc”, and “visible diffuse (aurora)”) and three non-aurora light source categories (“cloud”, “artificial light”, and “Moon”). Here, strong aurora means that the ordinary green color by atomic oxygen's 558 nm emission is either nearly saturated or mixed with red color at around 670 nm emitted, by molecular nitrogen. In stage (1b), the percentage of the occupying area (pixel coverage) for each category and the characteristic intensity of the strong aurora pixels are calculated. The obtained ASC auroral index is posted in both an ASCII format and plots in real time (https://www.irf.se/alis/allsky/nowcast/, last access: 11 April 2023). When Level 6 (local-arc breaking) is detected, an automatic alert email is sent out to the registered addresses immediately. The alert system started on 5 November 2021, and the results (both Level 6 detection and Level 4 detection) were compared to the manual (eye) identification of the auroral activity in the ASC during the rest of the aurora season of the Kiruna ASC (i.e., all images during a total of 5 months until April 2022 were examined and occasionally double-checked in the sky). Unless the Moon or the cloud blocks the brightened region, a nearly one-to-one correspondence between Level 6 and eye-identified local-arc breaking in the ASC images is achieved with an uncertainty of under 10 min.
Development and evaluation of a method to identify potential release areas of snow avalanches based on watershed delineation
Authors: Duvillier Cécile , Eckert Nicolas , Evin Guillaume , Deschâtres Michael
Published: April 2023

Abstract. Snow avalanches are a prevalent threat in mountain territories.
Large-scale mapping of avalanche-prone terrain is a prerequisite for
land-use planning where historical information about past events is
insufficient. To this aim, the most common approach is the identification of potential release areas (PRAs) followed by numerical avalanche simulations. Existing methods for identifying PRAs rely on terrain analysis. Despite their efficiency, they suffer from (i) a lack of systematic evaluation on the
basis of adapted metrics and past observations over large areas and (ii) a
limited ability to distinguish PRAs corresponding to individual avalanche
paths. The latter may preclude performing numerical simulations
corresponding to individual avalanche events, questioning the realism of
resulting hazard assessments. In this paper, a method that accurately identifies
individual snow avalanche PRAs based on terrain parameters and watershed
delineation is developed, and confusion matrices and different scores are
proposed to evaluate it. Comparison to an extensive cadastre of past
avalanche limits from different massifs of the French Alps used as ground
truth leads to true positive rates (recall) between 80 % and 87 % in PRA numbers and between 92.4 % and 94 % in PRA areas, which shows the applicability of the method to the French Alps context. A parametric study is performed, highlighting the overall robustness of the approach and the most important steps/choices to maximize PRA detection, among which the
important role of watershed delineation to identify the right number of
individual PRAs is highlighted. These results may contribute to better understanding
avalanche hazard in the French Alps. Wider outcomes include an in-depth
investigation of the issue of evaluating automated PRA detection methods and a large data set that could be used for additional developments, and to
benchmark existing and/or new PRA detection methods.
An assessment of short–medium-term interventions using CAESAR-Lisflood in a post-earthquake mountainous area
Authors: Wang Di , Wang Ming , Liu Kai , Xie Jun
Published: April 2023

Abstract. The 2008 Wenchuan earthquake triggered rapid local geomorphic
changes, shifting abundant material through exogenic processes and
generating vast amounts of loose material. The substantial material movement
increased the geohazard (flash floods, landslides and debris flows) risks
induced by extreme precipitation in the area. Intervention measures such as
check dams, levees and vegetated slopes have been constructed in specific
locations to reduce sediment transport and thereby mitigate the impact of
ensuing geohazards. This study assessed the short–medium-term effects of interventions,
including multiple control measures, in a post-earthquake mountainous
region. Taking the Xingping valley as an example, we used CAESAR-Lisflood, a
two-dimensional landscape evolution model, to simulate three scenarios,
unprotected landscape, present protected landscape and enhanced protected
landscape, between 2011 and 2013. We defined two indices to assess the
intervention effects of the three scenarios by comparing the geomorphic
changes and sediment yields. The results show that the mitigation measures are effective, especially the
geotechnical engineering efforts in combination with ecological engineering
in the upstream area. The spatial patterns of erosion and deposition change
considerably due to the intervention measures. Additionally, the
effectiveness of each intervention scenario shows a gradual decline over
time, mainly due to the reduction in the reservoir storage capacity. The
enhanced scenario performs better than the present one, with a more gradual
downward trend of effectiveness. The simulation results evaluated the
ability and effectiveness of comprehensive control measures and will support
optimal mitigation strategies.
Clinical Analysis of Techniques and Complications in 414 Consecutive Cochlear Implantations
Authors: Gauthaman Kavitha , MP Manoj
Published: April 2023

Aim: To report the frequency of surgical complications following 414 consecutive cochlear implant surgeries (402 children; 12 adults), of whom 323 underwent standard incision and 91 minimal access incision and to analyze the feasibility of using the minimal access ap-proach in all CI candidates. A careful assessment was performed to analyze whether the latter approach is more advantageous than the former in different quality parameters. Methods: Retrospective analysis of patients who underwent cochlear implant surgery from February 2012 to February 2019 by the same surgeon at a single center. Patients: 414 consecutively implanted patients (male: 51.33% female: 49.33%, Right: 68.66% Left: 26.66%, Bilateral: 4.66%).323 underwent a standard incision (Lazy S) and 91 underwent a minimal access incision. The average age of the standard incision group was 4.3years (range 9months-73years); that of the minimal access group 8.6 years (Range 9months-64years). The average incision size in the standard incision group was 7.61 cm and that of the minimum access group was 4.53cm. Results: Of the 414 patients who underwent surgery there were 30 surgery related complications (12 major, 18 minor), 11 device related complications. Major complications (5.3%) included wound infection (3); device extrusion (1); electrode displacement (2); temporary CSF leak (5) (in patients with cochleovestibular dysplasia’s); magnet displacement (1). The minor complications included transient fa-cial paresis (3); vertigo (2); seroma (9); hematoma (1); tinnitus (3). There were 11 device failures, one secondary to trauma the overall complication rate (9.6%) was low in our center when compared against available literature The mean operative time was 76 minutes for standard incision and 79.5minutes for the minimal access approach. A counter sink well for the receiver stimulator array was created and tie down of the device was done in all patients irrespective of the incision, except when a thin implant was used. Clinical Significance: Cochlear implantation is a low-risk procedure when performed by an experienced surgeon following standard protocol. Detailed preoperative workup, study of access and tailoring of the approach to suit each patient is a necessity to prevent com-plications. The minimal access incision causes less morbidity, is cosmetically more acceptable to patients and offers sufficient access to perform a cochlear implantation without compromising on vital steps.
Second Wave of COVID-19 in India

Published: April 2023

COVID Pandemic is a challenge but we, the Healthcare Professionals proved that we are good in the need of the hour in learning from each other and enabling society to protect both lives and livelihood. We are quite confident that anything is possible when we have the right people to associate and support us. These are times when we must take care of each other, our families and our society more than ever. This shall help us to create a positive atmosphere in these gloomy times. COVID-19 pandemic First Wave affected the most vulnerable sections of the population i.e. the old, sick and the immune-compro-mised. The Second Wave started when the infection started spreading into the general population, who may not have got the infection during the first wave and do not have protective antibodies against the virus. Experts have warned that a Third Wave of the COVID-19 Pandemic is inevitable, given the highest levels of circulating virus in India, but it is not clear on what timescale this 3rd Wave will occur. In third wave, the most vulnerable group would be the children as all adults are now being vaccinated on priority. Still we do not have the authorisation to vaccinate persons under 18 years of age. This could probably pose a problem later, as children are a big unexposed group for the virus. There is no single response to defeat the COVID-19 pandemic. Advance planning and preparation can help to avoid a repetition of the tragic circumstances caused by the second wave. We must be prepared for 3rd wave & remain optimistic about the whole situation. If we are not over prepared, 3rd wave will be more devastating to the lives & livelihood. Transparency in data collection and it’s collation, accelerating vaccination and transparency in vaccine deployment, setting up more COVID facilities with beds, oxygen supplies and staff, decentralization and equitable distribution of Medical aid and expanding & empowering rural infra-structure will go a long way in meeting this challenge. Continue investing in health as we move ahead, as Health Care investment have a compelling self-interest. We need to create our own robust Healthcare infrastructure with an effective health care delivery system, which is much more agile, accessible, comprehensive, compassionate and responsible for health promotion, prevention of illness, detection and treatment of disease and rehabilitation

The lymph nodes, particularly cervical nodes are affected in many infectious, autoimmune, metabolic and malignant diseases because they are the first drainage stations especially among children and can represent an early and subtle clinical sign. A careful choice of diagnostic procedures must be made to permit appropriate treatment. The spectrum of differential diagnoses vary from simple upper respiratory infections to malignant diseases. One such rare condi-tion is Sinus Histiocytosis which is associated with fever, massive bilateral lymphadenopathy. It is known to be associated with SLE or can mimic SLE. The condition commonly present in the first two decades of life. In our case of fever of unknown origin, diagnosis of Sinus Histiocytosis was made by lymph node biopsy but immunological profile was suggestive of mixed connective disorder. The case left a grey area unexplored whether MCTD can mimic or be associated with sinus histiocytosis.
Staying Protected for the Future – Immunization Beyond Covid Vaccines
Authors: Reddy B. Narender
Published: April 2023

Immunization is most effective and cost effective ways to prevent diseases in children. Despite clear evidence of prevention of diseases by vaccines its being missed out. COVID-19 has adversely affected every aspect of life including the vaccinations and increasing the risk in children for preventable diseases. Most of the children live in places where medical services are accessible with difficulty. Fear of falling ill and lack of visit to health care centre had become a major drawback. Several plans have been implemented by the Government in order to restore immunization by conducting vaccination campaigns helping care givers, rectifying mistakes in schedules, planning independent COVID-19 vaccine separately and plans to prevent vaccine preventable diseases. Without fear of any increased adverse effects all vaccines can be administered in the same session. WHO, UNICEF and development partners announced Immunization Agenda 2030 which has different principles.
What is Medical Negligence and How to Avoid Medical Negligence
Authors: Peddi Mallesham
Published: April 2023

Medical negligence is any harm caused due to negligent behaviour by any of the medical fraternity. Medical negligence can be either due to the doctor or the patient - doctors in hurry to treat many patients might miss some questions important for a diagnosis while patients may not reveal some important aspects regarding their health thinking those aspects may be less important. There-fore, a detailed history, thorough physical examination and getting investigations done when necessary may help in decreasing medical negligence. Few important points which all the doctors should keep in mind in day to day lives are given at the end.
Rupture of Spleen During Pregnancy with Intrauterine Fetal Death Mimicking Rupture Uterus: A Case Report
Authors: Reddy L Pranathi , Jaiswal Sarita
Published: April 2023

Background: Splenic rupture in pregnancy or postpartum is a rare and frequently misdiagnosed event. The splenic rupture during pregnancy is difficult to diagnose because it shares signs and symptoms with other conditions such as uterine rupture and abruptio placentae. Case report: We report a case of a 26 years G3P2L2 who had splenic rupture following accidental fall from the stairs. She presented with acute abdominal pain with hemoperitoneum and intrauterine fetal death. Ultrasonography confirmed moderate amount of free fluid and fetal demise without any evidence of retroplacental clots. She was taken up for emergency laparotomy with a provisional diagnosis of rupture uterus. On laparotomy, massive hemoperitoneum due to splenic injury was noted. Hence, Splenectomy was done and she recovered without further complication. Splenic rupture should be considered in cases of trauma to the abdomen during pregnancy because of the risk of severe haemorrhage, shock, and possibility of pregnancy loss. The aim of the article is to highlight the fact that rupture of the spleen is an unusual but serious cause of acute abdominal pain in pregnancy and is associated with both maternal and fetal complications. Conclusion: Sudden abdominal pain, pallor, and hypotension following any trauma may be a sign of splenic rupture. Resuscita-tion of patients with immediate laparotomy should be done in these patients to avoid fetal and maternal morbidity and mortality. Hence, it should be one of the differential diagnoses in addition to abruptio placentae and uterine rupture in suspected cases of haemorrhagic shock.
ALTERACIONES RADIOLÓGICAS DENTOMAXILARES MÁS FRECUENTES EN PACIENTES DE LA CLINICA ODONTOLÓGICA - UNIVALLE COCHABAMBA 2010
Authors: Guarayo Molina Edwin , Solis M. Edmundo
Published: April 2023

La radiografía dental es un valioso recurso auxiliar para el diagnóstico de las patologías en la cavidad bucal. Debe tenerse en cuenta que muchas patologías cursan de forma crónica y además sin una sintomatología manifiesta, es decir, que no presentan molestia alguna al paciente, por ello, existe una variedad de patologías que pueden ser descubiertas en un examen radiográfico de rutina y no por prescripción para cierta patología en especial.

Esta investigación fue de tipo prospectivo, transversal y descriptivo, con el objetivo de determinar las anomalías dentomaxilares de mayor frecuencia registradas en radiografías panorámicas de pacientes que acudieron al Servicio de Radiología de la Clínica Odontológica Univalle en el periodo comprendido entre el uno de marzo de 2010 al treinta de noviembre de 2010 según sexo y grupo etáreo.

El total de pacientes atendidos en este periodo fue de 616 pacientes, de los cuales la anomalía dental de mayor frecuencia en radiografías panorámicas fue la caries dental con 178 casos, la anomalía maxilar de mayor frecuencia fue el reborde óseo irregular con 9 casos. El sexo con mayor frecuencia de anomalías dentomaxilares correspondió al femenino con 385 casos y el rango de edad con mayor frecuencia de anomalías dentomaxilares fue el de pacientes mayores de 18 años con 387 casos.

Relevance: COVID-19 impacts the course of cancer depending on the status and volume of cancer patient vaccination against
COVID-19.
The study aimed to assess the impact of accelerated high-tech radiation therapy on the course of the oncological process, depending on the status and volume of COVID-19 vaccinations.
Methods: This quantitative and qualitative prospective randomized controlled scientific study was conducted as part of the implementation of the scientific project, “Innovative approach to managing patients with cancer in the context of the COVID pandemic-19,”
Reg. No. AP13068657. The study involved 221 cancer patients.
Results: COVID-19 was diagnosed in 54/221 (24.4%) of the study participants, 24 (22.4%) in the standard radiotherapy group, and
30 (26.3%) in the experimental radiotherapy group. 49/221 (22.2%) of the participants were vaccinated. COVID-19 was detected in
one breast cancer patient in the experimental group (1.5%) two months after vaccination and two patients with prostate cancer (2.4%)
four months after vaccination. Relapse-free survival was registered in 59 (85.5%) breast cancer patients in the standard group and
58 (85.3%) in the experimental group. The overall survival of breast cancer patients was 69 (100.0%) in the standard group and 68
(97.0%) in the experimental group. Relapse-free survival was registered in 32 (84.2%) prostate cancer patients in the standard group
and 41 (89.1%) patients in the experimental group. The overall survival among prostate cancer patients was 34 (89.5%) in the standard
group and 45 (97.8%) in the experimental group. The deaths were not related to COVID-19. The average treatment duration for breast
cancer was less by 12.9 days, with prostate cancer– by 18.2 days.
Conclusion: In Kazakhstan, 4.8% of cancer patients with COVID-19 died in 2020-2021. The use of accelerated high-tech radiotherapy is justified in the context of the COVID-19 pandemic. Vaccination can prevent COVID-19 development in cancer patients
