Background: Early diagnosis of laryngeal lesions is necessary to begin treatment of patients as soon as possible to preserve optimal organ functions. Imaging examinations are often aided by artificial intelligence (AI) to improve quality and facilitate appropriate diagnosis. The aim of this study is to investigate diagnostic utility of AI in laryngeal endoscopy. Methods: Five databases were searched for studies implementing artificial intelligence (AI) enhanced models assessing images of laryngeal lesions taken during laryngeal endoscopy. Outcomes were analyzed in terms of accuracy, sensitivity, and specificity. Results: All 11 studies included presented an overall low risk of bias. The overall accuracy of AI models was very high (from 0.806 to 0.997). The accuracy was significantly higher in studies using a larger database. The pooled sensitivity and specificity for identification of healthy laryngeal tissue were 0.91 and 0.97, respectively. The same values for differentiation between benign and malignant lesions were 0.91 and 0.94, respectively. The comparison of the effectiveness of AI models assessing narrow band imaging and white light endoscopy images revealed no statistically significant differences (p = 0.409 and 0.914). Conclusion: In assessing images of laryngeal lesions, AI demonstrates extraordinarily high accuracy, sensitivity, and specificity.

Background: The aim of this study was a comprehensive analysis of the incidence of different salivary gland pathologies in the adult population of Poland. Methods: A retrospective analysis of salivary gland pathologies diagnosed in Poland in 2010–2019 based on the National Health Fund (NHF) database was performed. Non-neoplastic diseases, and benign and malignant lesions were identified using ICD-10 codes. Demographic characteristics, incidence rates, and the number of inpatient and outpatient medical services were analyzed. Results: Salivary gland pathologies were diagnosed in 230,589 patients over 10 years (85.5% were non-neoplastic lesions, 11.53% benign and 2.93% malignant neoplasms). Incidence rate for all pathologies was 59.94/100,000. The mean incidence for malignant neoplasms was 1.78, and decreasing trend was observed over the analyzed period. Contrarily, for benign neoplasms (mean incidence—6.91), an increase in numbers was noted annually. The incidence for non-malignant lesions was quite stable (mean: 51.25) over the time. The highest number of medical services per patient concerned malignant neoplasms (on average, two hospital stays, and eleven outpatient consultations). Conclusions: An increase of benign salivary gland tumors, and a decrease of malignant neoplasms was observed during the studied period. The number of medical services related to salivary gland pathologies increased during the period under study.

Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder specific to pregnancy, typically presenting in the third trimester. It is characterized by pruritus, elevated serum bile acids, and abnormal liver function tests. While maternal symptoms resolve postpartum, ICP poses significant risks to fetal health, including spontaneous preterm labor, meconium-stained amniotic fluid, and stillbirth. This review aims to synthesize current knowledge on the pathogenesis, diagnosis, and management and highlight emerging research and possible therapy directions in ICP. A comprehensive review of recent literature was conducted, focusing on molecular mechanisms, clinical management guidelines, fetal outcomes, and novel therapeutics under investigation. Ursodeoxycholic acid (UDCA) remains the primary pharmacologic treatment of intrahepatic cholestasis of pregnancy; however, its effect on perinatal outcomes is debated. Investigational therapies—including Volixibat, FXR agonists, 4-phenylbutyrate, and NorUDCA—are under exploration. These emerging therapies hold the potential to improve both maternal symptoms and perinatal outcomes by addressing the underlying pathophysiology of ICP more effectively than current standard treatment. Additionally, emerging biomarkers and machine-learning tools hold promise for improved diagnosis and personalized care. ICP continues to pose diagnostic and therapeutic challenges. While maternal outcomes are generally favorable, optimizing fetal safety requires timely diagnosis, stratified risk assessment, and evidence-based delivery planning. Future research should prioritize identifying predictive biomarkers, refining treatment algorithms, and assessing long-term outcomes for both mothers and offspring. Special attention should also be given to the investigation of novel therapeutic targets.

Background: Cervical insufficiency (CI) is a painless cervix dilation in the second or early third trimester due to a structural or functional defect. However, CI is often diagnosed retrospectively. A cervix with CI cannot retain the fetus. This condition significantly increases the morbidity associated with extreme prematurity. Women diagnosed with cervical incompetence and dilatation in the mid-second trimester are offered interventions to prolong the duration of pregnancy, with the mainstay of therapy being emergency cerclage. A prophylactic cerclage may be offered to women with a history of extremely preterm birth due to isthmic cervical incompetence. Aim: The aim of this study was to evaluate the perinatal outcomes of elective and emergency cerclages. Materials and Methods: A 10-year retrospective analysis, from 1 January 2015 to 29 February 2024 of pregnancies with indications for cervical cerclage, was conducted. Obstetric and neonatal outcomes were assessed. Results: Prophylactic cervical cerclage was performed in 43 (57%) and emergency cerclage in 32 (43%) of all analyzed cases. The mean prolongation of gestation (measured as the period between cerclage insertion and delivery) was higher in the elective cerclage group compared with the emergency cerclage group (18.6 ± 5.4 vs. 12.2 ± 6.4 weeks; p < 0.0001). The mean gestational week at cerclage removal was also higher in the elective group (36.1 ± 2.2 vs. 31.4 ± 5.6 weeks; p < 0.001). Deliveries in the extreme prematurity period (before 28 completed weeks of gestation) were five times more often in the rescue cerclage group. A significantly higher mean birthweight was reported in the elective cerclage group, at 2920.4 ± 946.8 g vs. 2078.8 ± 1147.8 g (p = 0.0004). Emergency cerclage insertion was associated with a higher need for NICU hospitalization (28% vs. 5%, p = 0.003), continuous positive airway pressure (38% vs. 2%, p < 0.0001), and intubation (22% vs. 0%, p = 0.003). Conclusions: While elective cerclage is associated with more favorable perinatal and neonatal outcomes, this likely reflects earlier intervention in lower-risk pregnancies rather than inherent superiority of the approach. Emergency cerclage, performed under urgent and often suboptimal conditions, remains a critical and effective intervention capable of prolonging gestation and improving neonatal survival in high-risk cases.

(1) Background: Malignant tumours of the salivary glands have different clinical and histopathological characteristics. They most commonly involve the parotid gland. Histopathologically, the most common are mucoepidermoid carcinoma (MEC), adenoid cystic carcinoma (AdCC), acinic cell carcinoma (AcCC), adenocarcinoma, carcinoma in pleomorphic adenoma (CPA), and squamous cell carcinoma (SCC). (2) Methods: We analysed 2318 patients with malignant parotid gland tumours reported to the National Cancer Registry (NCR) in Poland over 20 years (1999–2018). The demographic characteristics of patients, clinical factors, and overall survival (OS) were analysed. (3) Results: The average age was 61.33 ± 16.1 years. The majority were males (55%) and urban citizens (64%). High percentage of carcinomas was diagnosed in locoregional (33.7%) and systemic (10.4%) stadium. The most prevalent diagnoses were SCC (33.3%) and adenocarcinoma (19.6%). Surgical resection with adjuvant RT (42.1%) was the most common treatment. The OS analysis showed a median survival time of 5.6 years. The most favorable median OS was found in patients with AcCC (18.30 years), the worst for SCC (1.58 years). (4) Conclusion: AcCC has the best prognosis and SCC the worst. Tumour stadium, treatment, and demographic factors affect prognosis. Improvements in diagnosis and re-evaluation of treatment standards are necessary to enhance the outcome of patients with parotid gland cancers in Poland.

Objective: The objective was to evaluate the optimal timing of cervical cerclage insertion for perinatal outcomes, such as birthweight, gestational week, and pregnancy prolongation in women with diagnosed cervical insufficiency (CI). Methods: This retrospective study was conducted at the 1st Department of Obstetrics and Gynaecology of the Medical University of Warsaw, over a 10-year period. Maternal and perinatal outcomes were compared between 75 women divided into three groups based on the gestational week (GW) at cerclage insertion: (1) before 18 GW (n = 31), (2) 18–22 GW (n = 31), (3) after 22 GW (n = 13). Only single pregnancies were included in the final analysis in order to maintain the homogeneity of the population. The primary outcomes included the week of delivery and pregnancy prolongation following cervical cerclage insertion. Numerous secondary outcomes were also evaluated, including neonatal mortality, need for NICU hospitalization, Apgar score, birthweight, maternal white blood cell (WBC) count and C-reactive protein (CRP) levels. Results: Birth week was significantly associated with GW at insertion—35.8 ± 3.8 vs. 34.8 ± 5.2 vs. 32 ± 5.7, respectively, p = 0.016. Moreover, statistical difference was also found regarding birthweight of the analysed groups—2723.8 ± 951.6 g vs. 2518.5 ± 1167.9 g vs. 1886.7 ± 1011.2 g, respectively, p < 0.001, and pregnancy prolongation following cerclage insertion 20.4 ± 4.2 vs. 14.7 ± 5.5 vs. 7.3 ± 5.7 weeks, respectively, p < 0.001. Conclusions: Earlier cerclage placement (22-week group). The sharp decline in outcomes after 22 weeks highlights the risks of advanced cervical dilation, suggesting that clinical management should prioritize risk assessment within the prophylactic window.
