Background: Sentinel lymph node (SLN) biopsy is recommended over systematic lymphadenectomy in early-stage endometrial cancer due to its lower morbidity and comparable detection rate. The objective of this study was to identify clinical factors associated with unsuccessful mapping. Methods: Between April 2020 and June 2024, 120 patients over the age of 18 and diagnosed with early-stage endometrial cancer were enrolled in this prospective study at a single institution. Demographic, clinicopathologic, and treatment data were collected and analyzed using descriptive statistics. Univariate and multiple linear regressions were performed to identify predictors of failed mapping. Results: The mean age of the patient cohort was 62.5 years (range 33 to 83), and the mean body mass index (BMI) was 32 kg/m² (range 18 to 50). Patients underwent intracervical injections with methylene blue (MB), indocyanine green (ICG), or a combination of both tracers, with 40 patients in each group. A total of 108 patients (90.0%) were diagnosed with endometrioid carcinoma and 12 (10.0%) with non-endometrioid cancers. Additionally, 110 patients (91.7%) were diagnosed in early stages of the disease. The overall SLN detection rate was 73.4%, with bilateral detection at 49.2% and unilateral detection at 24.2%. Univariate analysis showed that older age (p < 0.001), menopause (p = 0.001), the use of MB as the sole tracer (p = 0.006), a shorter tumor-to-serosa distance (p = 0.048), and bulky lymph nodes (p = 0.18) were associated with unsuccessful mapping. Multiple linear regression model analysis identified age (p = 0.007), tracer type (p = 0.013), and enlarged lymph nodes (p = 0.013) as independent predictors of SLN mapping failure. Conclusions: Advanced age, tracer type, and intraoperative detection of enlarged lymph nodes were identified as independent risk factors for unsuccessful mapping in patients undergoing laparoscopic SLN mapping.

Osteogenesis imperfecta (OI), also known as brittle bone disease, belongs to a rare heterogeneous group of inherited connective tissue disorders. In experienced prenatal centers, severe cases of OI can be suspected before birth from the first trimester prenatal ultrasound screening. In this article, we describe a case report of OI suspected at the 26th week of gestation and the patient’s outcomes in infancy one year after birth, as well as compare our case to other prenatally or soon-after-birth suspected and/or diagnosed OI clinical case reports in the literature. This case was managed by a multidisciplinary team. In this clinical case, OI was first suspected when prenatal ultrasound revealed asymmetric intrauterine growth restriction and skeletal dysplasia features. The diagnosis was confirmed after birth using COL1A1 gene variant detection via exome sequencing; the COL1A1 gene variant causes OI types I–IV. The familial history was negative for both pregnancy-related risk factors and genetic diseases. At one year old, the patient’s condition remains severe with bisphosphonate therapy.

Background: Sentinel lymph node (SLN) biopsy in early-stage endometrial cancer is recommended over systematic lymphadenectomy due to reduced morbidity and comparable detection rates. The main objective of this study was to compare the overall and bilateral detection rates of SLN in early-stage endometrial cancer using three techniques. Methods: a prospective cohort study was designed to detect the difference in SLN detection rate in three cohorts: Indocyanine green (ICG), methylene blue (MB), and tracer combination (ICG + MB). Mapping characteristics, detection rate, number of SLNs, and positive SLNs of the three cohorts were compared. Results: A total of 99 patients were enrolled. A total of 109 SLN sites with 164 lymph nodes were detected. No differences were found between the three cohorts in terms of age, BMI, tumor diameter, or other histologic characteristics. The overall SLN detection rate (DR) was 54.3% in the MB group, 72.7% in ICG, and 80.6% in the ICG-MB group. Bilateral DR was 22.9%, 39.4%, and 54.8% in groups, respectively, with the MB method yielding significantly inferior results. Conclusions: The ICG-MB group demonstrated superior overall and bilateral detection rates, but a significant difference was found only in the MB cohort. Combining tracer agents can enhance the accuracy of SLN identification in initial-stage endometrial cancer without additional risk to the patient.

The occurrence of more than one primary malignant tumor in a single patient is rare. Multiple primary malignancies can pose difficulties in differential diagnosis between primary tumors and metastasis. Here, we present a case report with multiple primary malignancies. The patient is a 45-year-old female who was diagnosed with cervical mixed squamous neuroendocrine adenocarcinoma, metastasized carcinosarcoma and extramammary vulvar Paget’s disease. The patient was first diagnosed with a microinvasive squamous cervical carcinoma in situ. After a few months, the amputation of a small residual tumor and histological evaluation revealed an IA1-stage poorly differentiated (G3) mixed squamous and neuroendocrine cervical adenocarcinoma. After two years, the disease had progressed and biopsies from altered sites were taken. Histological diagnosis from an ulcerated vulvar region revealed extramammary vulvar Paget’s disease. A biopsy from vagina polyp revealed an earlier diagnosed mixed squamous and neuroendocrine cervical adenocarcinoma. However, histological diagnosis from an inguinal lymph node biopsy was unexpected and revealed carcinosarcoma. It indicated either the development of another primary malignancy, or an unusual spread of metastasis. Clinical presentation as well as diagnostic and treatment challenges are discussed in this case report. This case report shows that multiple primary malignancy cases are difficult to manage both for clinicians and the patient because the therapeutic options can become limited. This complex case was managed by a multidisciplinary team.

Acute abdomen during pregnancy is rare. Despite advances in diagnostic imaging, preoperative diagnosis in the pregnant population due to anatomical and physiological changes can pose difficulties. Diagnosis and surgery delays increase the risk of adverse outcomes for both maternal and fetal health. In symptomatic cases, explorative surgery might be essential for correct diagnosis and patient treatment. Here, we present Meckel’s diverticulum as an unusual cause of small bowel obstruction complicated with gangrene in a 34-week pregnant patient. The diagnosis was only apparent during explorative surgical laparotomy.

Įgimtos širdies ydos – vienos dažniausiai diagnozuojamų raidos ydų, nustatomos 8–10 iš 1 000 kūdikių. Sudėtingų įgimtų širdies ydų diagnostika iki gimimo lemia mažesnį naujagimių sergamumą ir mirštamumą ankstyvuoju laikotarpiu. Įprastai vaisiaus širdies yda įtariama atrankinio vaisiaus ultragarsinio tyrimo metu, tikslinama atliekant detalųjį vaisiaus širdies ultragarsinį tyrimą. Vaisiaus stebėsena, gydymo taktika ir prognozė priklauso nuo teisingos ir išsamios diagnozės, todėl labai svarbu, kad vaisiaus echokardiografijos duomenys būtų kuo tikslesni. Vis dėlto, diagnostika išlieka sudėtinga dėl vaisiaus širdies ultragarsinio tyrimo specifikos, skirtingo prenatalinių ir ponatalinių ydų spektro hemodinamikos savitumų, kompleksinių ydų anatomijos sudėtingumo, ydų progresavimo galimybės nėštumo laikotarpiu, kai kuriais atvejais – gretutinių raidos ydų bei ligų. Straipsnyje išanalizuoti trys Vilniaus universiteto Santaros klinikose gydytų naujagimių, kuriems dar iki gimimo įtartos sudėtingos širdies ydos, klinikiniai atvejai (pasirinkti atvejai, kurių prenatalinė ir ponatalinė diagnozės skyrėsi). Palyginti sudėtingų įgimtų širdies ydų prenatalinės ir ponatalinės diagnozės panašumai ir skirtumai, įvertintas vaisiaus echokardiografijos tikslumas, atlikta literatūros apžvalga.
