Epidemiological aspects and malacofauna of the São Francisco River, northeastern Brazil

Limnic mollusks could negatively affect the ecosystem in which they are found, the economy, human and animals´ health. This study reports on a survey of freshwater sources mollusks and their spatial distribution, as well as investigating them for the presence of trematodes in the municipality of Nossa Senhora de Lourdes, Sergipe, Brazil. This study was performed through March 2016 and November 2017. The mollusks were collected in different water bodies in the georeferenced studied area, identified and analyzed for the presence of trematodes. Thirty-four water bodies were sampled, and mollusks were found in 18 (53%) of them. From the 5,196 found, 4,747 (91%) were gastropods and 449 (9%) bivalves - distributed in seven families and eleven species. Among the species found, two are of medical-veterinary importance (Biomphalaria straminea and Melanoides tuberculata) and four are exotic invasive species (Corbicula fluminea, C. largillierti, Limnoperna fortunei and M. tuberculate). Of the 1,473 mollusks analyzed for trematodes, five (0.33%) gastropods were infected, one specimen contained Vivax, two Pleurolophocercous, and two Virgulate. For the first time these six taxa have been described in the State of Sergipe: Drepanotrema depressissimum, D. cimex, D. lucidum, Ancylidae, Physa acuta and C. largillierti. This survey contributes to the knowledge of the biodiversity and spatial distribution of limnic mollusks and the presence of trematodes, in addition to serving to support the monitoring and prevention of exotic bio invasive species, and intermediate hosts, since the studied area presented potential for helminth transmission. KEY WORDS: Snails; trematodes freshwater sources; spatial distribution; exotic and invasive mollusks; Sergipe State.

Coronary artery anomalies: what are they? when to suspect? how to treat?-a narrative review.

In the literature have been widely discussed different classification criteria for coronary artery anomalies (CAAs), some authors have tried to categorize them only as "major" or "hemodynamically significant" anomalies versus "minor" or "not hemodynamically significant" ones. However, the most recent literature has concluded that all possible coronary anatomy should be taken into consideration in a comprehensive classification of CAAs. The aim of the article is to review the most recent literature regarding CAAs to provide a comprehensive overview of this challenging topic. We propose a narrative overview of the most impactful and recent literature, synthetizing and re-elaborating the most important articles concerning CAAs. The important gap of knowledge on the specific characteristics of CAAs has led to a progressively increased interest of the current research in this field. Albeit their nature is still unclear, an increased awareness of their fatality is spreading among clinicians and the general population, mostly associated with their clinical relevance among young patients and athletes. On the other side, we do believe that clinical and hemodynamic repercussions are of crucial importance and should always be integrated to understand the true nature of this important pathology. In the field of pediatric cardiology, CAAs are one of the most fascinating and studied subject. We propose a state-of-the art review to provide a comprehensive and systematic description and subsequently an approach to the epidemiological, pathophysiological, and clinical aspects of the most important CAAs in the pediatric population.

Aspectos clínicos, epidemiológicos e terapêuticos da hipocalcemia puerperal em cadelas

This study aims to analyze the clinical, epidemiological and therapeutic aspects of puerperal hypocalcemia in bitches, following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Seven articles were selected for detailed analysis after a selection and exclusion process. The main clinical signs of puerperal hypocalcemia in bitches include muscular tetany, epileptic seizures, ataxia and tachypnea. This condition is more prevalent in small dogs in the postpartum period, aged between 3 and 4 years, and in medium to large litters. Different therapeutic approaches were discussed, highlighting the administration of 10% calcium gluconate and the importance of weaning the puppies as a crucial part of the animal's recovery process. The lack of uniformity in clinical and therapeutic aspects compromises the effectiveness of treatment, highlighting the pressing need for more research on the topic.

Resurgence of influenza with increased genetic diversity of circulating viruses during the 2022-2023 season.

Introduction. After two seasons of absence and low circulation, influenza activity increased significantly in the winter of 2022-2023. This study aims to characterize virological and epidemiological aspects of influenza infection in Bulgaria during the 2022-2023 season and perform a phylogenetic/molecular analysis of the hemagglutinin (HA) and neuraminidase (NA) sequences of representative influenza strains.Hypothesis/Gap Statement. Influenza A and B viruses generate new genetic groups/clades each season, replacing previously circulating variants. This results in increased antigenic distances from current vaccine strains. Strengthening existing influenza surveillance is essential to meet the challenges posed by the co-circulation of influenza and SARS-CoV-2.Methodology. We tested 2713 clinical samples from patients with acute respiratory illnesses using a multiplex real-time RT-PCR kit (FluSC2) to detect influenza A/B and Severe acute respiratory syndrome coronavirus-2(SARS-CoV-2) simultaneously. Representative Bulgarian influenza strains were sequenced at the WHO Collaborating Centres in London, UK, and Atlanta, USA.Results. Influenza virus was detected in 694 (25.6 %) patients. Of these, 364 (52.4 %), 213 (30.7 %) and 117 (16.9 %) were positive for influenza A(H1N1)pdm09, A(H3N2) and B/Victoria lineage virus, respectively. HA genes of the 47 influenza A(H1N1)pdm09 viruses fell into clades 5a.2. and 5a.2a.1 within the 6B.5A.1A.5a.2 group. Twenty-seven A(H3N2) viruses belonging to subclades 2b, 2a.1, 2a.1b and 2a.3a.1 within the 3C.2a1b.2a.2 group were analysed. All 23 sequenced B/Victoria lineage viruses were classified into the V1A.3a.2 group. We identified amino acid substitutions in HA and NA compared with the vaccine strains, including several substitutions in the HA antigenic sites.Conclusion. The study's findings showed genetic diversity among the influenza A viruses and, to a lesser extent, among B viruses, circulating in the first season after the lifting of anti-COVID-19 measures.

Pseudofolliculitis barbae in police students in Dakar: epidemiological and clinical aspects, and associated risk factors

Pseudofolliculitis barbae (PFB) is a chronic inflammatory skin disease favoured by shaving. It is particularly common among black Africans belonging to certain socio-professional categories who are obliged to shave. Its aesthetic and professional damage is very significant. However, very few data are available for this condition, especially in Sub-Saharan Africa. To determine the epidemiological and clinical aspects, and the risk factors associated with the occurrence of PFB in Dakar. This was a descriptive cross-sectional study conducted in March 2019, including 655 police students at the National Police Academy in Dakar, all of African descent and with curly hair, who were required to shave weekly and agreed to participate in this study. The diagnosis of PFB was clinically based. Data analysis was processed using Epi-info version 6.0 software. Pearson's chi-square test was used for bivariate analysis with a significance threshold of p < 0.05. The Odds Ratio, with its 95% confidence interval, was used to determine the risk factors. Among the 655 officers, 254 had PFB, with a prevalence of 38.8%. The prevalence of PFB was 43.7% in men (242 men out of 554) and 11.9% in women (12 women out of 101). The average age of patients with PFB was 26.80 years (± 2.59), ranging from 22 to 36 years. The age of onset of PFB was between 18 and 20 years for the majority (39.8%), with a mean age of onset of 22.2 years (± 3.6). PFB lesions were pruritic in 84.6% of cases, papular in 96.8%, and/or pustular in 60.2%. The submandibular region was the most affected site (69.8%). Complications were noted in 90.1% of cases in the form of post-inflammatory hyperpigmentation (87%) and keloid scars (3.1%). The risk factors associated with PFB were male sex (p<0.0001; OR=5.7; CI95% [3.07-10.75]), family history of PFB (p<0.0001; OR=5; CI95% [3.35-7.37]), keloid-prone skin (p<0.0001; OR=2.9; CI95% [1.63-4.96]), association with acne keloidalis nuchae (p<0.0001; OR=8.8; CI95% [5.55-14.08]), use of a single-blade razor (p<0.0001; OR=2.5; CI95% [1.69-3.70]), use of a fixed-head razor (p<0.0001; OR=1.8 CI95% [1.28-2.77]), shaving against the grain (p<0.0001; OR = 6.3; CI95%= [4.33-9.08]), non-use of shaving products (p = 0.009; OR = 1.5; CI95%= [1.06-2]) and waxing (p<0.004; OR=2.7; CI95% [1.33-5.77]). On the other hand, the use of clippers (p<0.0001; OR = 0.5 CI95% [0.33-0.65]), pre-shave products (p<0.0001; OR = 0.4 CI95% [0.29-0.61]) and the use of razors with movable heads (p<0.0009; OR = 0.2 CI95% [0.17-0.35]) were protective factors against PFB. Our study confirms the high incidence of PFB in this population of black men of African descent. A genetic abnormality revealed by shaving must be evoked in the occurrence of PFB. Further genetic and immunohistochemical studies would be needed to support this hypothesis.

Epidemiological and Etiological Aspects of Acute Renal Failure in the Nephrology and Haemodialysis Department of the Point G University Hospital

Introduction: Acute renal failure (ARF) represents a major public health problem associated with high mortality. The incidence is increasing with the emergence of multiple risk factors. In Mali, there are currently no data on the extent and severity of this condition in either hospital or community settings. The aim of our study was to describe the epidemiological, therapeutic and prognostic aspects of ARF in adults treated at the University Hospital Centre (CHU) of Bamako. Patients and Methods: This was a retrospective and descriptive study that took place from 1 July 2021 to 30 June 2022 at the CHU du Point G in Bamako. It focused on patients hospitalised and/or followed up on an outpatient basis in the nephrology department during the study period. Results: The prevalence of acute renal failure was 11.55% with a sex ratio of 1.49. The mean age was 42.37±20.7 (range 6-88 years). Elevated plasma creatinine was the main reason for consultation. Creatinine levels were above 500µmol/l in 65.21% of cases. High blood pressure was the main presenting condition in 33.7% of cases. Acute renal failure was organic, obstructive and functional in 72.8%, 15.2% and 12% respectively. Rehydratation was used in 97.8% of cases. Dialysis was indicated in 40% of cases. Age over 60 years was a major risk factor for ARF. The outcome was favourable in 81.5% of cases. Conclusion: Mortality in dialysis patients with ARF remains high. Several factors influence the prognosis of these patients, including the severity of ARF and pre-existing comorbidity.

Dental caries in schools in the city of N'Djamena in Chad: Epidemiological aspects and oral habits in pupils aged from 6 to 12 years

Dental caries is a global disease that can have disabling effects. In Africa, its prevalence in schools is very variable, due to the great variability of food habits and oral hygiene. This study aimed to assess the prevalence of dental caries, associated factors, and to research oral pathologies associated with that dental decay in one circumscription of the city of N'Djamena. This was a cross-sectional study conducted in 3 schools in the 7th borough of the city of N'Djamena. A total of 360 pupils aged between 6 and 12 years were recruited between October 2021 and September 2022. Each participant underwent to an oral examination which consisted in looking carefully at the pupil's face (cheeks, lips) to note any deformities or possible facial asymmetry, and to check for any sensation of pain in any part of the face. In another hand, the oral examination aimed to look for any decay on all the teeth and determine the category and class of it. Finally, the personal data (age, sex, class, parents' occupations) of each participant and the results of his oral examination were collected into a database and analyzed. A total of 185 pupils had at least one decayed tooth, giving a prevalence rate of 51.4%. Among them, 45% had at least 2 decayed teeth. The school attended and snacking between meals were significantly associated with the presence of caries (p<0.05). Teeth 36 (lower left first molar) and 46 (lower right first molar) were the most often affected by caries (21% and 22% respectively). The mixt DMF index was 0.6 and the overall frequency of decayed teeth was 51.9%. According to Black's classification, class II caries was the most prevalent (48%), while according to Baume's classification, category II was the most prevalent (54%). The time of brushing, the material and the type of product used significantly influenced the appearance of caries (p<0.05). Participants with dental dyschromia had more tooth decay. Caries was prevalent in the targeted schools and represented a real problem for pupils. Implementing an oral health policy based on preventive dentistry by raising awareness among children and their parents would contribute to the proper education of pupils.

Análise epidemiológica e hematológica de cães naturalmente infectados por Hepatozoon spp. da região central do Brasil – estudo retrospectivo

Hepatozoonosis is a hemoparasitosis caused by intracellular protozoa of the genus Hepatozoon, transmitted to dogs and other carnivores by parasitized ticks, such as Rhipicephalus sanguineus and Amblyomma spp. Its prevalence varies by geographic region, favoring tropical and subtropical areas. Hepatozoon spp. infection cause nonspecific clinical manifestation. This longitudinal retrospective study aims to highlight the epidemiological and hematological aspects of dogs naturally infected with Hepatozoon spp. in the municipality of Mineiros, state of Goiás, Brazil, between 2018–2022. This study considered the following information: age, sex, breed, distribution of cases over the years, seasonality, and hematological profile. A total of 272 domestic dogs were found to be parasitized by Hepatozoon spp. using the blood smear technique. Adult dogs were more likely to be affected by hepatozoonosis, with no breed or sexual predisposition. This study showed an exponential increase in cases diagnosed over the years, particularly in autumn and winter (the dry season). Within the study’s evaluation criteria, most dogs had anemia, thrombocytopenia, and hyperproteinemia; however, there were no changes in the total leukocyte count.

Auricular and periauricular pathologies in the ENT department of Sylvanus Olympio Teaching Hospital in Lome (Togo)

The aim of this study is to describe the epidemiological aspects, clinical features and principles of management of different types of auricular and peri-auricular pathologies. This is a 5-year retrospective descriptive study (from May 1, 2018 to April 30, 2023) of the records of patients who consulted for a functional or cosmetic complaint relating to the auricle or periauricular region in the ENT and cervico-facial surgery department of the Centre hospitalier universitaire Sylvanus Olympio. A total of 159 cases over 5 years, i.e. an annual frequency of 31 cases, met the study criteria. The mean age of the patients was 22.2 years. Children and students accounted for 24.5% and 23.9% of cases respectively. Auricular pathologies accounted for 64.8% of cases and peri-auricular pathologies for 36.2%.Tumors and trauma accounted for 33.3% and 29.6% of cases respectively, and congenital pathologies were found in 29.9% of cases. Among traumatic lesions, intentional assault and battery was the cause in 21.3%, followed by road accidents in 17.2%. The right ear was affected in 48% and the lobule in 40.4%. Keloids accounted for 17.6% of all cases, and 53% of tumors and pseudotumors. The left ear was involved in 50% of cases. Piercing was the cause of keloids in 10.7% of cases. Auricular and peri-auricular pathologies were dominated by benign tumors, trauma and congenital pathologies, and involved young subjects. Management is based on the type of lesion, with functional and aesthetic considerations in mind.

PROFILE OF ISCHEMIC STROKE IN CHILDREN: EXPERIENCE OF THE UNIVERSITY HOSPITAL CENTER OF OUJDA

Ischemic strokes (IS) in children are rare but critical, presenting unique challenges due to age-specific factors. Defined by the American Heart Association as episodes of neurological dysfunction caused by focal infarctions, IS can lead to severe outcomes if not promptly addressed. Despite their rarity, pediatric IS requires careful management, complicated by the lack of validated treatment data for children. This study from the University Hospital Center of Oujda examines the management of acute IS in children, analyzing epidemiological aspects, clinical presentations, and therapeutic approaches. Results : 1. Population: 29 children, average age 3.5 years, slight male predominance (sex ratio: 1.2). 2. Consultation Delay: 14% were seen within 24 hours 50% after 7 days. 3. Symptoms: Motor deficit was the most common (82.7%). 4. Diagnostics: CT confirmed IS in 85% of cases MRI established etiological diagnosis in 51.8%, showing sylvian artery involvement in all patients. 5. Etiologies: Embolic cardiopathies (31.03%), vasculopathies (20.06%), and others such as hypertension and neurofibromatosis. 6. Treatments: Symptomatic management, motor physiotherapy, aspirin, and heparin. 7. Outcomes: 74% had complete regression of motor deficits, 20.6% had partial regression, and there were two deaths due to cardiogenic shock. The study underscores the need for a multidisciplinary approach to effectively manage IS in children and improve clinical outcomes.

코로나 이환 경험자를 대상으로 주관적 구강상태 인지와 미각 역치 간의 상호관계 분석

Objectives: The purpose of this study was to confirm the analysis of taste threshold and evaluate the relationship between taste threshold and changes in taste according to oral factors and COVID-19 disease. Methods: In this study, a total of 203 female college students participated. Taste thresholds for five tastes were measured. Information on subjective oral environment and potential COVID-19 effects on taste thresholds was gathered through a questionnaire. Results: Sweetness stood out with the highest sensitivity at 4.19 among the five basic tastes. Subjects occasionally experiencing subjective bad breath showed significant sensitivity to sour taste (sometimes 3.12, never 2.47). Individuals frequently perceiving a subjective dry mouth exhibited heightened sensitivity to bitter taste, scoring 4.13, significantly higher than the 3.38 observed when there was no dryness. While taste thresholds did not significantly differ for those with confirmed coronavirus cases, there was a general tendency for elevated thresholds across all tastes. Subjects with altered smell during COVID-19 diagnosis were notably more sensitive to sour tastes, with a statistically significant difference. Changes in taste and smell correlated positively, with most correlations showing significant positive associations. Conclusions: This study COVID-19 infection led to taste and smell changes, but post-recovery taste thresholds remained unaffected. These findings contribute to understanding the epidemiological aspects of taste and serve as foundational data for exploring taste changes, significant as oral-related clinical symptoms of COVID-19, a classified class 4 infectious disease.

Ecological Epidemiology: A Perspective from One Health

Ecological epidemiology is a distinct branch of the science of epidemiology that focuses on the complex interactions between environmental factors and population health. Instead of examining individuals in isolation, ecological epidemiology analyzes entire groups and the relationships among biological, social, and environmental factors. Its main concern is identifying the influence of the environment on the distribution of diseases within communities. In this review, we aim to analyze the main aspects of ecological epidemiology, covering everything from definition and methods to practical applications and specific challenges.

Clinico-epidemiological characteristics and long-term surgical outcome of basal cell carcinoma treated with standard excision in patients of skin of colour: A retrospective study from Northern India.

Background There is scant data on basal cell carcinoma (BCC) in Indian patients. This retrospective study was conducted to explore epidemiology, risk factors, clinical and pathological aspects, and long-term treatment outcomes of BCC in a cohort of North Indian patients. Methods Data about patients registered in the dermatosurgery clinic between 01 January 2017 and 31 December 2022 with a confirmed diagnosis of BCC was collected. Results Among the 83 patients, 56.6% were females, and the median age was 62 years (6-85 years). Most patients (81.9%) had a single BCC lesion, resulting in a total of 126 assessed lesions. The median size of BCC at presentation was 1.90 cm, with nodular BCC being the most common histopathological subtype (39.7%). Head and neck region involvement was observed in 82.5% of patients, with the malar region, nose, and periorbital region being the most commonly affected sites. Pigmentation was clinically evident in 45.2% of cases. Surgical excision was the primary treatment modality (71.1% of patients). The median follow-up duration was 40 months (6-57 months). Recurrence occurred in five patients, with a longer disease-free survival period observed in the surgically treated group (55.58 ± 0.98 months) compared to patients treated with medical or destructive therapies (43.6 ± 3.482 months) (p = 0.003). Conclusion The data from this hospital-based study indicated a slight predilection for females among North Indian patients with BCC, with most cases occurring during their seventh decade of life. The condition commonly occurred on sun-exposed areas such as the malar region and nose, with a high percentage of pigmented lesions. Recurrence following surgical excision was rare, and overall treatment outcomes were favourable.

Molecular signature of gliomas correlated to clinical epidemiological aspects of patients in follow-up at a reference center in São Paulo - Brazil - COMU 2023

We have prepared a manuscript that represents our analysis regarding our study. Gliomas are more than 80% of all primary brain cancers and 24% of all brain tumors 1. In 2021, the new edition of WHO - Classification of Tumors of the Central Nervous System (WHO- CTCNS) 2 established genetic and molecular aspects to the analysis since they could be correlated to characteristics of tumor behavior and clinical-epidemiological features. However, there are few studies correlating molecular analysis to the clinical follow-up of patients in Brazil. We performed a preliminary, observational, prospective and descriptive study that aims to obtain and to compare clinical-epidemiological data to molecular markers of patients in follow-up at Central Hospital of Santa Casa de São Paulo (HC-ISCMSP).

Vascular catheter-related infections: an endemic disease in healthcare institutions. An opinion paper of the Spanish Society of Cardiovascular Infections (SEICAV).

Catheter-related infections (CRI) are a serious healthcare problem due to their potential to cause serious complications, including bacteraemia or infective endocarditis, and to increase patient morbidity and mortality. In addition, these in fections significantly prolong hospital stay and cost. Preventing CRI is crucial and is considered a criterion for quality and safety in healthcare. For these reasons, the Spanish Society of Cardiovascular Infections (SEICAV) has considered it pertinent to review this topic, with experts in different areas including clinical microbiologists, infectious disease specialists, surgeons and nurses. The data were presented at a session held at the Ramón Areces Foundation, which was organised in the form of specific questions grouped into three round tables. The first panel analysed the scale of the problem including epidemiological, clinical and diagnostic aspects; the second panel addressed advances in the treatment of CRI; and the third panel reviewed developments in the prevention of CRI. The recorded session is available on the Areces Foundation website and we believe it maybe of interest not only to health professionals, but also to any non-expert citizen interested in the subject.

Epidemiological, virological and clinical characterization of a Dengue/Zika outbreak in the Caribbean region of Costa Rica 2017-2018.

The increase in incidence and geographical expansion of viruses transmitted by the Aedes mosquitoes, such as dengue (DENV) and zika (ZIKV) in the Americas, represents a burden for healthcare systems in tropical and subtropical regions. These and other under-detected arboviruses co-circulate in Costa Rica, adding additional complexity to their management due to their shared epidemiological behavior and similarity of symptoms in early stages. Since diagnostics of febrile illness is mostly based on clinical symptoms alone, we gathered acute-phase serum and urine from 399 samples of acute dengue-like cases from two healthcare facilities of Costa Rica, during an outbreak of arboviruses from July 2017 to May 2018, and tested them using molecular and serological methods. The analyses showed that of the clinically presumptive arbovirus cases that were reported, only 39.4% (n=153) of the samples were confirmed positive by RT-PCR to be DENV (DENV (10.3%), CHIKV (0.2%), ZIKV (27.3%), or mixed infections (1.5%). RT-PCR for other alphaviruses and flaviviruses, and PCR for Leptospira sp were negative. Furthermore, to assess flavivirus positivity in post-acute patients, the negative sera were tested against Dengue-IgM. 20% of sera were found positive, confounding even more the definitive number of cases, and emphasizing the need of several distinct diagnostic tools for accurate diagnostics. Molecular characterization of the prM and E genes from isolated viruses revealed that the American/Asian genotype of DENV-2 and the Asian lineage of ZIKV were circulating during this outbreak. Two different clades of DENV-2 American/Asian genotype were identified to co-circulate in the same region and a difference in the platelet and leukocyte count was noted between people infected with each clade, suggesting a putative distinct virulence. Our study sheds light on the necessity for healthcare strategies in managing arbovirus outbreaks, emphasizing the importance of comprehensive molecular and serological diagnostic approaches, as well as molecular characterization. This approach aids in enhancing our understanding of the clinical and epidemiological aspects of arboviral diseases during outbreaks. Our research highlights the need to strengthen training programs for health professionals and the need to increase research-based on laboratory evidence for diagnostic accuracy, guidance, development and implementation of public health interventions and epidemiological surveillance.

Sexual Assault of the Female Gender Admitted to the "One Stop Centre" Unit in Commune I of the District of Bamako: Epidemiological, Clinical and Legal Management Aspects

Sexual violence is an all-encompassing expression that designates "any sexual act, attempt to obtain a sexual act, comment or advance of a sexual nature directed against a person's sexuality using coercion. The general objective was to study sexual assaults based on the female gender in the "One Stop Center" unit of the reference health center in commune I of the district of Bamako, Republic of Mali. Methodology: This was a descriptive cross-sectional study of sexual assaults on women admitted to the commune I One Stop Center. All survivors of sexual assault admitted to the One Stop Center during the study period were included; confidentiality and anonymity were respected. Results: We recorded 224 cases of victims of gender-based violence out of 10,924 gynaecological consultations received at the department, a frequency of 2.05%. Of the 224 victims of gender-based violence admitted to the One Stop Centre, 109 (48.66%) were victims of sexual assault. The average age of the patients was 14.12 ± 5.06 years, with extremes of 2 and 36 years. The victims were all female. The majority of survivors (94%) were single. More than half of the victims (55%) were pupils. More than half of the assaults (57.8%) took place between 7pm and midnight. 60.6% of the assaults took place at the survivors' homes. In 8% of cases, weapons were threatened. We found that hymenal lesions were predominant in 76.2% of cases. HIV serology was positive in 1% of victims. Antibiotic prophylaxis was the predominant medical treatment in 69.7% of cases. Suture of the vulvo-perineal tear was the surgical treatment in 2.8% of cases. Out-of-court settlements were the solution in the majority of cases (20.18% of cases), followed by withdrawal of the complaint to the court (6.4% of victims). Conclusion: This study has shown that sexual violence against women is increasing in scale and severity despite the regulatory and legislative framework
