The study aimed to calculate the livelihood vulnerability of organic and non-organic rice farmers' households to climate change. The sample was determined by a census comprising 60 organic and 80 non-organic rice farmers who lived in Pematang Sawa Sub-district, Tanggamus Region, Lampung Province, Indonesia. The livelihood vulnerability index (LVI) was measured based on seven main indicators: natural disaster and climate variability, agriculture profile, food security, water security, food/rice consumption, educational attainment, and income. The results showed that organic rice farmers' households were more vulnerable in terms of natural disaster and climate variability, water security, food consumption, education, and income, while non-organic rice farmers' households were more vulnerable in terms of agriculture profile and food security. Using the LVI framework approach of the Intergovernmental Panel on Climate Change (LVI-IPCC), non-organic rice farmers’ households were found to be more vulnerable to climate change than organic rice farmers' households. To better observe the vulnerability of organic and non-organic rice farmers' households to climate change, future studies should be conducted in two distant locations (e.g., different regions or provinces) because different climate components could significantly influence the findings. Rice farmers' households could become less vulnerable by providing them with objective climate information that will encourage them to adopt the necessary climate change adaptation and mitigation strategies. Further support is needed in the form of resources aid programs, such as the provision of irrigation systems or pumping wells, as well as livestock aid to increase the farmers’ income.

Methods for handling sewage sludge from sewage treatment plants
Authors: Shakhova Irina M.
Published: March 2023

Inconsistency of regulatory legal acts often does not allow unambiguously determining the applicability of legislative requirements to a specific type of activity. The article provides an analysis of the concepts established in the legislation, as well as an attempt to understand the requirements for enterprises when handling sewage sludge from sewage treatment plants. Due to the imperfection of environmental legislation and the similarity of technological processes, the treatment of sewage sludge during its treatment at sewage treatment plants is often classified by regulatory authorities as waste disposal. Such categorization entails the need for organizations operating sewage treatment plants to obtain licenses. The absence of a license in such a case leads to penalties against the company operating the treatment facilities and its officials.
Reloading of the international transport corridor "North-South"
Authors: Mineev Valery I. , Pochekaev Dmitry A.
Published: March 2023

The agreement on the creation of the international transport corridor "North-South" between Russia, Iran and India was signed in September 2000. The contracting parties intended to increase trade exchange and transit traffic in order to accelerate economic growth both in the countries themselves and in the regions of the route. Subsequent events in the world contributed to the introduction of serious adjustments that had a negative impact on its development: a series of economic downturns, the US invasion of Iraq and Afghanistan, the emergence of the One Belt, One Road Initiative, and Russia's special military operation in Ukraine. All this led to a significant change in commodity flows and an understanding of the significance of this transport corridor.

Aim: Cancer is one of the most common health problems in the world. Music is a therapy method that creates positive changes in human behavior. This study aims to examine the effects of Turkish and Western classical music on MCF-7, SKOV-3, PC-3, U87, and COLO741 cancer cell lines.
Material and Methods: Group 1: No sound, Group 2: Turkish classical music (ney), Group 3: Western classical music (piano), and Group 4: Western classical music (violin). After listening to the cancer cells for 40 min, the audio files were interrupted for 1h, and then music was played for another 40 min. The effect of music on the proliferation of cancer cells was determined by WST-1 cell viability analysis. Statistical analyzes were performed with the SPSS program.
Results: There was no statistically significant difference between the groups that were applied music once in only the MCF-7 breast cancer cells and the control group (p>0.05). A statistically significant decrease was detected in cell viability when the control group and the other groups that were applied to music twice were compared (p<0.05). For other cancer cell lines except (please the SKOV-3 ovarian cancer cells, it was determined that music application once also caused a statistically significant decrease in cell viability (p<0.05).
Conclusion: We determined that classical music effectively reduced and suppressed the number of cancer cells. According to the data, Turkish and Western classical music can be used to support the treatment in of cancer patients.

Aim: Gestational diabetes mellitus (GDM) is associated with an increased risk of fetal and maternal complications, such astype 2 DM (diabetes mellitus) and cardiovascular disease (CVD). This study aimed to predict the potential for future vascular complications in mothers with GDM by evaluating oxidative stress, endothelial NO synthase (eNOS) expression, and vascular smooth muscle cell (VSMC) proliferation in the umbilical vessels of mothers with GDM. Material and Methods: Subjects were divided into two groups: the normoglycemic control (NGC) group (n = 10) and the GDM group (n = 12). Expression of eNOS and production of reactive oxygen species (ROS) in human umbilical vein endothelial cells (HUVECs) were determined. The mitochondrial mass of HUVECs was evaluated by spectrofluorometry. VSMC proliferation was ascertained in vitro with an EdU cell proliferation assay. Advanced glycation end products (AGEs) accumulation was measured by ELISA and assessed by immunohistochemical staining Results: VSMC proliferation, eNOS expression, and ROS production in HUVECs were significantly increased, and greater immunohistochemical staining to AGEs was observed in endothelium in GDM. Conclusion: Increased oxidative stress, which elevates eNOS expression and VSMC proliferation in the umbilical vessels of mothers with GDM, may be a sign that mothers have a high potential for developing diabetes or cardiovascular disease in the future.
Correlation of Fine Needle Aspiration Cytology and Histopathological Evaluation in Salivary Gland Masses: A Single Center Retrospective Study
Authors: GÜN Seda , CAN Bilge 
Published: March 2023

Aim: Fine-needle aspiration cytology (FNAC) in the preoperative diagnosis of salivary gland (SG) masses is a very fast, inexpensive, and reliable diagnostic method. In our study, the correlation of cytological-histopathological diagnosis in cases diagnosed with fine needle aspiration cytology in our clinic was investigated, and possible causes of diagnostic entrapment in discordant cases were discussed.
Material and Methods: Salivary gland FNAC cases with histopathological diagnosis between 2008 and 2019 were retrospectively analyzed.The age, gender, localization of the lesion, preoperative cytology, and postoperative histopathological diagnosis of the patients were recorded. Cytology results were analyzed in 5 categories: unsatisfactory, uncategorized, benign, suspected malignancy, and malignant. Histopathology results were recorded in 2 groups benign-nonneoplastic and malignant. Statistically significant difference level was accepted as p<0.05. The validity of the cytology result according to the biopsy result was evaluated by sensitivity, specificity, positive predictive value, and negative predictive value.
Results: 316 cases of salivary gland fine needle aspiration were detected. 156 (49.4%) of 316 cases had histopathological diagnosis. When calculating the cytological-histopathological diagnosis, the cases that were found to be inadequate and uncategorized by cytology were not taken into consideration. The suspected malignancy group was evaluated within the malignant category. Therefore, diagnostic agreement was calculated in 124 cases. Of these 124 cases, 116 (93.6%) cytology-histopathology diagnosis were compatible, and 8 (6.4%) were not.
In our series, the overall sensitivity and specificity were 83.3% and 97.7%, respectively. The positive predictive value was 93.7% and the negative predictive value was 93.4%. The accuracy rate was calculated as 93.5%.
Conclusion: In our study, high sensitivity and specificity values were determined by FNAC in accordance with the literature. It should be kept in mind that there may rarely be differences between preoperative cytological and histopathological diagnoses, possibly due to experience, method, and lesion-related limitations and pitfalls.

Aim: In this study, we investigated the immune activity of the Sox-9 and Cited-1 in women with placenta accreta. Material and Methods: 20 healthy and 20 placenta accreta were processed for routine histological tissue processing. Placentals samples were dissected and fixed in 10% formaldehyde solution. Samples were embedded in paraffin blocks. Clinical and biochemical parameters were recorded. Placental sections were cut from paraffin blocks and stained with Sox-9 and Cited-1 immunostaining. Results: In our study, control group showed negative Cited-1 expression in decidual cells, root villi and connective tissue areas in general. Placenta accreta group showed increased Cited-1 expression in degenerated decidual cells, fibroblastic cells and endothelium. In control group, Sox-9 expression was negative in the syncytial knots, in the vascular endothelial cells. In placenta accreta group, Sox-9 reaction was positive in the root villi, in the blood vessels, in the connective tissue. Conclusion: It was observed that the Sox-9 reaction was increased and inflammation was induced, depending on the differences in decidual cells, in the syncytial area and in the vascular endothelium in in placentas of women with placenta accreta. It is thought that Sox-9 signaling processes are being determined and Cited-1 may be stimulants that affect cell proliferation and angiogenesis regulation and affect placental development.

Authors: AYHAN Mustafa
Published: March 2023

Aim: In our study, we aimed to measure the amount of released head by recording it with a thermal camera during the osteotomies made utilizing round, fissure and lindemann burs to the synthetic bone blocks to simulate the mandible ramus region which is often preferred when obtaining autogenous bone from the mouth.
Material and Methods: The burs in our study were used at rotational speeds of 10000 rpm and 15000 rpm and feed rates of 60 mm/min and 90 mm/min, and each osteotomy was made with a CNC milling machine in order to standardize the applied force.
Results: According to the results of our study, the highest temperatures were observed in the fissure bur groups, and the round bur and lindemann bur groups gave similar results. In addition, when the feed rate is increased from 60 mm/min to 90 mm/min in all groups at constant rotational speed, the heat released increases significantly. When the groups are evaluated within themselves; the temperature values observed at 15000 rpm and 60 mm/min feed rate in the groups using round bur were found to be significantly lower than the group observed at 10000 rpm and 60 mm/min feed rates (p=0.028), in fissure bur groups, the temperature values observed at 10000 rpm and 60 mm/min feed rate were significantly lower than the values observed at 15000 rpm and 60 mm/min feed rates (p=0.028). No statistically significant difference was observed between the heat exchange averages of the 10000 rpm and 15000 rpm groups at a Lindemann bur 60 mm/min feed rate (p=0.182).
Conclusion: This study has shown that while the generated heat in the bone is thought to increase when the bur speeds are increased, the head generated according to bur designs can decrease and it is necessary to operate according to the characteristic features of the preferred bur.

The Effect of Metallicity on the Nonequilibrium Abundance of Hydrogen-dominated Exoplanet Atmospheres
Authors: Soni Vikas , Acharyya Kinsuk
Published: March 2023

The atmospheric metallicity greatly influences the composition of exoplanet atmospheres. The effect of metallicity on the thermochemical equilibrium is well studied, though its effect on the disequilibrium abundance is loosely constrained. In this study, we have used the quenching approximation to study the effect of metallicity on the quenched abundance for a range of parameters (temperature: 500–2500 K, pressure: 10−4–103 bar, metallicity: 0.1–1000× solar metallicity). We determine the chemical timescale by finding rate-limiting steps in a reduced chemical network with a network-analysis tool and the thermochemical equilibrium abundance. The equilibrium abundance results are similar to the literature. The CO, H2O, and CO2 abundances increase with metallicity in the parameter range considered. The CH4 abundance increases with metallicity for CO/CH4 < 1 and is unaffected for CO/CH4 > 1. The chemical timescale of CO shows minimal change with metallicity, while the CH4 chemical timescale is inversely proportional to atmospheric metallicity. The quench level of CO shifts into the high-pressure region, and the quench level of CH4 shows complex behavior with metallicity. We benchmarked the quenching approximation with a one-dimensional photochemistry-transport model for two test exoplanets (GJ 1214 b and HD 189733 b) and found it to be in good agreement. We also found that the quenching approximation is a powerful tool to constrain atmospheric parameters. We demonstrated this by constraining the metallicity and transport strength for the test exoplanets HR 8799 b, HD 189733 b, GJ 436 b, and WASP-39 b.
The Ages of Galactic Bulge Stars with Realistic Uncertainties
Authors: Joyce Meridith , Johnson Christian I. , Marchetti Tommaso , Rich R. Michael , Simion Iulia , Bourke John
Published: March 2023

Using modern isochrones with customized physics and carefully considered statistical techniques, we recompute the age distribution for a sample of 91 microlensed dwarfs in the Galactic bulge presented by Bensby et al. and do not produce an age distribution consistent with their results. In particular, our analysis finds that only 15 of 91 stars have ages younger than 7 Gyr, compared to their finding of 42 young stars in the same sample. While we do not find a constituency of very young stars, our results do suggest the presence of an ∼8 Gyr population at the highest metallicities, thus contributing to the long-standing debate about the age–metallicity distribution of the Galactic bulge. We supplement this with attempts at independent age determinations from two sources of photometry, BDBS and Gaia, but find that the imprecision of photometric measurements prevents reliable age and age uncertainty determinations. Lastly, we present age uncertainties derived using a first-order consideration of global modeling uncertainties in addition to standard observational uncertainties. The theoretical uncertainties are based on the known variance of free parameters in the 1D stellar evolution models used to generate isochrones, and when included, result in age uncertainties of 2–5 Gyr for this spectroscopically well-constrained sample. These error bars, which are roughly twice as large as typical literature values, constitute realistic lower limits on the true age uncertainties.
The Mass Fallback Rate of the Debris in Relativistic Stellar Tidal Disruption Events

Published: March 2023

Highly energetic stellar tidal disruption events (TDEs) provide a way to study black hole characteristics and their environment. We simulate TDEs with the Phantom code in a general relativistic and Newtonian description of a supermassive black hole’s gravity. Stars, which are placed in parabolic orbits with different β parameters, are constructed with the stellar evolution code MESA and therefore have realistic stellar density profiles. We study the mass fallback rate of the debris

The paper presents an analysis of multiwavelength data of a nearby star-forming site, the IC 5146 dark streamer (d ∼ 600 pc), which has been treated as a single and long filament, fl. Two hub-filament systems (HFSs) are known to exist toward the eastern and the western ends of fl. Earlier published results favor simultaneous evidence of HFSs and end-dominated collapse (EDC) in fl. A Herschel column density map (resolution ∼13.″5) reveals two intertwined sub-filaments (i.e., fl-A and fl-B) toward fl, displaying a nearly double helix-like structure. This picture is also supported by the C18O(3–2) emission. The fray and fragment scenario may explain the origin of intertwined sub-filaments. In the direction of fl, two cloud components around 2 and 4 km s−1 are depicted using 13CO(1–0) and C18O(1–0) emission and are connected in velocity space. The HFSs are spatially found at the overlapping areas of these cloud components and can be explained by the cloud–cloud collision scenario. Nonthermal gas motion in fl with a larger Mach number is found. The magnetic field position angle measured from the filament’s long axis shows a linear trend along the filament. This signature is confirmed in the other nearby EDC filaments, presenting a more quantitative confirmation of the EDC scenario. Based on our observational outcomes, we witness multiple processes operational in the IC 5146 streamer. Overall, the streamer can be recognized as the first reliable candidate for edge collapse, HFSs, and intertwined sub-filaments.

Published: March 2023

Cette étude s’est intéressée aux représentations maternelles du père de l’enfant et à la prévalence de la dépression post-natale (DPN) chez un échantillon de 30 mères célibataires tunisiennes. Pour l’étude de représentation maternelle, nous avons eu recours à l’entretien « R » durant le 3 e trimestre de grossesse des femmes. La dépression post-natale a été évaluée à travers des entretiens cliniques de type semi-directif, ainsi qu’avec la version tunisienne de l’EPDS, à la 1 ère semaine après l’accouchement (T1) et à la 6 e semaine après l’accouchement (T2). Les résultats de l’entretien « R » montrent que toutes les mères célibataires ont une représentation négative du père de l’enfant. Les résultats de l’EPDS montrent que 20 % des mères célibataires présentent une DPN. Nos résultats montrent l’importance de la prise en compte du facteur culturel dans l’étude de la maternité célibataire.
Co-production des savoirs sur l’usage de drogues et réduction des injustices épistémiques
Authors: Jauffret-Roustide Marie , Debrus Marie
Published: March 2023

L’usage de drogues est habituellement envisagé sous l’angle d’un double cadrage juridique et biomédical, produisant des classifications des usagers de drogues autour des figures de délinquant et de malade. La politique de réduction des risques a fait évoluer les représentations et la place des usagers dans les politiques qui leur sont destinées en favorisant leurs capacités d’agir dans le processus de limitation de l’exposition aux risques associés aux usages et en particulier à l’injection. Notre recherche socio-anthropologique à dimension participative menée avec Médecins du Monde a étudié la mise en œuvre du programme d’éducation à l’injection (ERLI) à partir d’entretiens auprès d’usagers, de professionnels et de bénévoles et d’observations ethnographiques de sessions d’injection. Notre recherche met en évidence les dimensions à la fois intimes et politiques qui traversent le programme. Elles donnent lieu à un échange et un partage de savoirs, d’affects et d’émotions ainsi qu’à des négociations et des tensions entre usagers, professionnels et bénévoles. Cette volonté de réduction des injustices épistémiques inhérente au programme ERLI met à l’épreuve les ethos professionnels des intervenants et révèle la manière dont l’exposition au risque chez les usagers est modelée par l’environnement du risque.

Enquêter sur les conditions d’une jeunesse sexuelle derrière les barreaux permet de se pencher sur le travail de contrôle que des adultes exercent de façon plus ou moins directe sur la sexualité des jeunes. À partir d’une enquête empirique menée par entretiens et observations dans différentes prisons françaises, on s’intéressera à la place des surveillant·e·s en détention dans la gestion quotidienne de la sexualité, qui permettra une description des modalités du contrôle carcéral sur la sexualité et l’intimité des jeunes détenu·e·s. Plus généralement, cet article propose de considérer la prison comme espace de maintien de l’ordre genré, y compris en tenant compte de la configuration spatiale des prisons et des rapports sociaux entre professionnel·le·s.
Transition chronologique. Peine de mort, débats parlementaires et révolutions (France, 1791-1848)

Published: March 2023

Entre les années 1790 et 1848, dans les décennies qui suivent le Dei delitti e delle pene , de Beccaria, la France connaît ses premiers grands débats parlementaires sur l’abolition de la peine capitale. De premières abolitions sont alors tentées. Une chronologie, agrémentée de textes fondateurs, permet de souligner le lien alors étroit entre expériences révolutionnaires et disparition de la peine de mort, qui a conduit à l’abolition différée (1795), avortée (1830), puis partielle (1848) de la peine de mort.

Música, mito e historia de El Dorado ¿Carlos Saura versus Werner Herzog ?
Authors: Bloch-Robin Marianne
Published: March 2023

En este artículo analizamos el papel de la música en la película de Carlos Saura El Dorado (1987) a partir del estudio de la partitura arreglada por el compositor Alejandro Massó. Si bien en la concepción de su película basada en numerosas fuentes histórica, el director aragonés apuesta por oponerse a la obra de Werner Herzog Aguirre, Der Zorn Gottes (1972), también centrada en la aventura del hidalgo vasco Lope de Aguirre en busca de la ciudad mítica de El Dorado, la banda musical, de las que analizamos dos obras más particularmente – La Recercada (1553) de Diego Ortiz y un fragmento del preludio del tercer acto de Tristan und Isolde (1865) de Richard Wagner – contribuye a conferir a la película una dimensión mítica y universal que la desliga en cierta medida de la referencia histórica diegética y la aproxima a la obra de Herzog.
L’Arc de Triomphe et les Champs-Élysées comme signifiants politiques et littéraires : Une approche comparatiste des romans sur Mai 68
Authors: Clemente Escobar Ángel
Published: March 2023

Les éléments urbains (rues, places, édifices, monuments) peuvent être compris comme les signifiants d'un discours social plus large. Le sens de ces éléments est déterminé aussi bien par leur cadre général que par leur morphologie et les événements qui s'y déroulent. Certains de ces éléments se comportent au niveau idéologique comme ces « signifiants flottants » nommés par le théoricien argentin Ernesto Laclau. Le sens de ces signifiants n'est pas complètement fixé, car il dépend de la forme discursive adoptée par les rapports de force d'une société donnée. De la même façon que les signifiants abstraits identifiant cette même société, les signifiants urbains sont particulièrement sensibles, en temps de crise, à la lutte entre les différents acteurs sociaux.Notre objectif est d’aborder les événements de Mai 68 à Paris dans la perspective de leur développement spatial et de l’affrontement discursif qui en découle, en nous concentrant sur l’une des parties les plus significatives de la ville, celle de l'Arc de triomphe et des Champs-Élysées. Nous illustrerons notre analyse par quelques représentations littéraires de ces événements, la création littéraire constituant une partie fondamentale de la réception de ce récit historique.
Dante et Pound pour Pasolini : La force révolutionnaire du passé
Authors: Passerone Giorgio
Published: March 2023

À quoi sert l’événement-Pasolini à l’heure du marché mondial des « sociétés de contrôle » qu’avait annoncé son « sombre enthousiasme » devant l’homologation du néo-capitalisme italien des années 70 ? La nécessité de poser ce problème implique la tentative de ne pas renfermer Pasolini dans la réflexivité d’une exégèse qui finit trop souvent par ressasser « la structure intime du contraste interne, irrésolu », l’amphibologie et l’« oxymoron » de son œuvre et de sa vie. C’est « hors » de la reconnaissance de ses déterminations biographiques et textuelles, psychanalytiques et historiques, qu’il faut aller à la rencontre d’ une œuvre et d’une vie dans leurs résonances hérétiques, transhistoriques, avec Dante et Pound, également étrangers à eux-mêmes : nous pourrons en extraire l’expérimentation d’une commune force révolutionnaire qui innerve l’art(isant) d’un passé oublié à travers les luttes minoritaires d’aujourd’hui contre le marché universel pour le devenir d’un monde autre.
Histoire, littérature, fiction : à partir du cas Saviano
Authors: Boillet Étienne
Published: March 2023

Certaines des idées exprimées par Manzoni, à propos des rapports entre l’histoire et le roman, peuvent trouver un écho chez des théoriciens de la fiction tels que Genette. C’est à partir de ce possible dialogue que nous abordons Gomorra de R. Saviano. L’auteur présente son livre comme une œuvre de non-fiction, genre dont il fait l’éloge en dénonçant l’ostracisme qu’aurait subi un roman comme De sang-froid de T. Capote (1966) et en se félicitant de la reconnaissance récente dont témoigne le prix Nobel 2015 attribué à S. Alexievicth. Mais ce discours tend aussi à effacer la frontière entre les récits strictement non fictionnels et les enquêtes romancées par l’ajout d’éléments inventés : il semblerait même que, pour l’auteur napolitain, ce soit justement cette part de fiction qui permette à l’enquête historique ou journalistique d’accéder à la littérarité et à une forme supérieure de vérité. C’est là un positionnement qu’on retrouve dans la critique, auprès de chercheurs qui, subordonnant en outre la question de la distinction entre fiction et non-fiction à l’enjeu de la modernité, voient dans Gomorral’expression emblématique d’un nouveau réalisme, avec lequel se tournerait enfin la page de la postmodernité. Nous examinons ici quelques aspects notionnels relatifs à ces questions, dans le cadre d’une interrogation plus large sur la frontière entre fiction et non-fiction.
Inhaled Corticosteroids Is Not Associated with the Risk of Pneumonia in Asthma
Authors: Lee Ye Jin , Park Yong-Bum
Published: March 2023

The introduction of inhaled corticosteroids (ICS) for the management of asthma has led to a decrease in acute exacerbation of asthma. However, there are concerns regarding the safety of long-term ICS use, particularly pneumonia. Growing evidence indicates that ICS use is associated with an increased risk of pneumonia in patients with chronic obstructive pulmonary disease, whereas the risk in patients with asthma remains unclear. This review discusses the effect of ICS on pneumonia among patients with asthma to update the existing literature. Asthma is associated with an increased risk of pneumonia. Several hypotheses have been proposed to explain this association, including that asthma impairs the clearance of bacteria owing to chronic inflammation. Therefore, controlling airway inflammation with ICS may prevent the occurrence of pneumonia in asthma. In addition, two meta-analyses investigating randomized control trials showed that ICS use was associated with a protective effect against pneumonia in asthma.
Research progress of selective brain cooling methods in the prehospital care for stroke patients
Authors: Chen Xi , An Hong , Wu Di , Ji Xunming
Published: March 2023

Over the past four decades, therapeutic hypothermia (TH) has long been suggested as a promising neuroprotective treatment of acute ischemic stroke (AIS). Much attention has focus on keeping the hypothermic benefits and removing side effects of systemic hypothermia. In the past few years, the advent of intravenous thrombolysis and endovascular thrombectomy has taken us into a reperfusion era of AIS treatment. With recent research emphasizing ways to plus neuroprotective treatments to reperfusion therapy, the spotlight is now shifting toward the study of how selective brain hypothermia can offset the drawbacks of systemic hypothermia and be applied in prehospital condition. This mini-review summarizes current brain cooling methods that can be used for inducing selective hypothermia in prehospital care. It will guide the future development of selective cooling methods, extend the application of TH in prehospital care, and provide insights into the prospects of selective hypothermia in AIS.

Dextrocardia is a rare congenital developmental anomaly where the heart is located in the right hemithorax with the cardiac apex pointing toward the right. Dextrocardia may be associated with total situs inversus or can also present as an isolated finding. We present very rare interesting case of situs inversus totalis in a 68-year-old male patient who came with complaints of difficulty in breathing and had a history of fever for 4 days. In view of the COVID-19 pandemic, he got his real time polymerase chain reaction done and he turned out to be positive. On the imaging dextrocardia with total situs inversus was detected. Even though for a common man, dextrocardia with total situs inversus is only heart on the right side of the body with transposition of the abdominal organs, viscera, and vasculature but from a medical point of view, the diagnosis holds a lot of importance as it is useful in the detection of conditions like appendicitis and abdominal organ injuries.
Comparative Study of Postoperative Astigmatism Following Phacoemulsification with Scleral Incision and Posterior Chamber Foldable and Rigid (Nonfoldable) Intraocular Lens Implantation
Authors: Ambadkar Sweta , Thool Archana
Published: March 2023

Purpose:

To study and compare the postoperative astigmatism following phacoemulsification with scleral incision and posterior chamber foldable and rigid (nonfoldable) intraocular lens (IOL) implantation.

Materials and Methods:

It was a hospital-based prospective observational study which included 200 eyes with presenile and senile cataract and were divided into two groups. Group I; included hundred cases with superior scleral incision (3.2 mm) phacoemulsification and foldable posterior chamber IOL (PCIOL) implantation. Group II; included 100 cases with superior scleral incision (5.5 mm) phacoemulsification and rigid (nonfoldable) PCIOL implantation. The data were analyzed by Chi-square test and P < 0.05 was considered statistically significant. The surgically induced astigmatism (SIA) at 6 weeks was compared between the two groups. SIA was calculated by the vector analysis.

Results:

The mean SIA in Group I was 0.67 ± 0.46 D, whereas in Group II was 1.17 ± 0.44 D. There was statistically significant difference between the two groups P < 0.05. Group II showed higher mean SIA than Group I at 6 weeks. Postoperatively, majority of patients developed against the rule astigmatism, 62% in Group I and 76% in Group II.

Conclusion:

SIA is less in 3.2 mm incision as compared to 5.5 mm incision with increase in against the rule astigmatism postoperatively.
An Unusual Cause of Massive Epistaxis in a 13-Year-Old Boy
Authors: Swain Santosh Kumar , Mahapatra Ashok Kumar
Published: March 2023

Epistaxis is often encountered among pediatric patients as otorhinolaryngological emergency. However, massive epistaxis in a child is extremely rare, especially arising from the pseudoaneurysm of the cavernous part of the internal carotid artery (ICA). Here, we present the case of a 13-year-old boy presented with the sudden onset of massive epistaxis with a previous history of head injury 1 month ago. The nasal bleeding was controlled by nasal packing followed by computed tomography angiography confirmed the diagnosis of cavernous ICA pseudoaneurysm. Then, the patient underwent endovascular coil embolization and symptom free at 6 months and 1-year follow-up. Massive epistaxis in a pediatric patient is a potentially lethal clinical condition. It needs timely diagnosis and early treatment.
Does Delayed Presentation of Posterior Urethral Valve Carry Worse Prognosis?
Authors: Guru Nilesh , Lakhkar Bhavana , Guru Bhushita , Dhale Abhijit , Dharamshi Jay
Published: March 2023

Posterior urethral valve (PUV) is the most common cause of lower urinary tract obstruction in male neonates, with an incidence of 1 in 8000–25,000 live births. The clinical course of PUV diagnosed late in life is quite unpredictable. The prognosis of late-diagnosed PUV depends chiefly on the renal function at presentation. A literature search was performed on the delayed presentation of PUV. Serum creatinine at presentation, nadir serum creatinine (defined as the lowest creatinine attained in the year after valve ablation), and renal parenchymal echogenicity were significant predictors of final renal outcome. A generalization cannot be made regarding the prognosis of late-presenting PUV patients. The prognosis varies from case to case. If renal function at presentation and after valve ablation is preserved, then late-presenting PUVs carry good prognosis. Age per se does not carry any prognostic significance.
