Metastasis of cutaneous melanoma to the oral cavity is a rare condition. Male patient with cutaneous melanoma metastasis to right tonsil 2 years after radical skin lesion resection was treated with surgery: tonsillectomy and later resection of soft palate were performed. Two years later the patient was diagnosed with progressive disease to right tonsil and soft palate. Rapid inoperable relapse was detected six months later. The patient underwent two procedures of palliative cryoablation of the metastasis. Postoperative course was uneventful. Patient died 7 months later due to progression of the disease. Cryoablation alone or together with surgery may be a relatively safe option for treatment of inoperable disease of head and neck tumours.

Background and objectives: The most effective treatment of infertility is in vitro fertilization (IVF). IVF with Preimplantation Genetic Testing (PGT) allows to identify embryos with a genetic abnormality associated with a specific medical disorder and to select the most optimal embryos for the transfer. PGT is divided into structural rearrangement testing (PGT-SR), monogenetic disorder testing (PGT-M), and aneuploidy testing (PGT-A). This study mostly analyzes PGT-SR, also describes a few cases of PGT-M. The aim of this study was to implement PGT procedure at Vilnius University Hospital Santaros Klinikos (VUHSK) Santaros Fertility Centre (SFC) and to perform retrospective analysis of PGT procedures after the implementation.

Materials and methods: A single-center retrospective analysis was carried out. The study population included infertile couples who underwent PGT at SFC, VUHSK from January 01st, 2017 to December 31st, 2020. Ion PGM platform (Life Technologies, USA) and Ion ReproSeq PGS View Kit (Life Technologies, USA) were used for the whole genome amplification. Results were assessed using descriptive statistics.

Results: PGT was successfully implemented in VUHSK in 2017. During the analyzed time period, thirty-four PGT procedures were performed for 26 couples. Two procedures were performed in 2017, 7 procedures - in 2018, 13 - in 2019, and 12 - in 2020. In comparison with all IVF procedures, 2.5% procedures were IVF with PGT, a highest percentage was in 2020 (3.8% of all procedures). The main indication for PGT was balanced chromosomal rearrangements (in 85.3% cases). In all 34 cases 515 oocytes were aspirated in total, 309 oocytes were fertilized, oocytes fertilization rate exceeded 60%. A normal diploid karyotype was found in 46 (16.8%) biopsied embryos. Out of all PGT procedures, 9 (26.5%) resulted in a clinical pregnancy. Six (66.7%) pregnancies were confirmed in 2019, and 3 (33.3%) - in 2020. Three (33.3%) pregnancies resulted in spontaneous abortion, 6 (66.7%) - in delivery.

Conclusions: The implementation of PGT in VUHSK was successful. The most common indication for PGT was a reciprocal translocation. Oocytes fertilization rate exceeded 60%, a normal karyotype was found less than in one-fifth of biopsied embryos. A highest clinical pregnancy rate was achieved in 2019 when almost half of women conceived, which is probably related to the experience gained by the multidisciplinary team. This is the first study analyzing IVF with PGT in Lithuania, however, the results should be interpreted with caution due to a low number of total procedures performed.

Objectives: The invasion of Russian troops into independent Ukraine has changed the humanitarian situation in the Kharkiv region. The paper is focused on the peculiarities and issues of the management of labor and delivery near the front line.

Materials and methods: Totally 2030 patients were enrolled in the study. 1410 women who delivered in the second half of 2021 were enrolled in Group I. 620 women who delivered in the first half of 2022 were observed in Group II. Some patients from Group II were used for the investigation of the comparative situation during first months of 2022. 85 women who delivered in January were included in Subgroup IIA. 94 women who have completed their pregnancies and delivered in February were observed in Subgroup IIB. 67 case histories of deliveries which occurred during March were united in Subgroup IIC.

Results: The level of anemia, uterine contractile activity in labor abnormalities, and episiotomies were surprisingly lower during wartime in March. The obtained results showed an almost similar level of obstetric complications, maternal comorbidities, and interventions during labor and delivery in all groups. The stressed environment was a possible reason for the elevation of cardiovascular disease and endocrine disorders.

Conclusion: The study did not reveal any significant changes in the structure of maternal pathologies and obstetric complications during the first months of wartime near the front line. But later the levels of cardiovascular disease and endocrine disorders were found to be elevated.

Aim: The aim is to evaluate the pregnancy outcomes of patients with uterus unicornis for 5-year experience in a tertiary center.

Material and method: Twenty patients with uterus unicornis who were diagnosed with hysterosalpingography and/or 3D TVUSG between 2017 and 2021 and then confirmed with laparoscopy and simultaneous hysteroscopy were recruited into this retrospective study. The reproductive outcome and obstetric complications of the patients were followed up for two years postoperative period.

Results: Overall 20 patients who fulfilled the inclusion criterion were recruited for the study. The mean age was 28.65±5.03 years. Thirteen patients (65%) had primary infertility while the remaining seven had secondary infertility with two of them having a previous ectopic pregnancy. Rudimentary communicating uterine horn was observed in 7 (35%) of the patients. The horns were excised during laparoscopy. Overall, 14 (70%) pregnancies were achieved during the 2 years follow-up period. Twelve (85.7%) patients had a live birth (71.4% term delivery, 21.4% preterm delivery), and two (15.3%) had a first-trimester spontaneous abortion. Six (50%) of 12 patients who had a live birth received tocolytics for preterm labor.

Conclusion: Unicorn uterus is a rare anomaly diagnosed mostly during infertility work-up and might be related to the poor obstetric outcome, but early diagnosis is important for successful pregnancy results for preterm delivery especially in the secondary infertile group. In addition, rudimentary horn excision is recommended due to the high risk of obstetric complications.

Background: Nonsyndromic craniofacial clefts are relatively common congenital malformations which could create a significant negative effect on the health status and life quality of affected individuals within the pediatric population. Multiple cleft candidate genes and their coded proteins have been described with their possible involvement during cleft formation. Some of these proteins like Homeobox Protein BarH-like 1 (BARX1), Distal-Less Homeobox 4 (DLX4), Forkhead Box E1 (FOXE1), Homeobox Protein Hox-B3 (HOXB3), and Muscle Segment Homeobox 2 (MSX2) have been associated with the formation of craniofacial clefts. Understanding the pathogenetic mechanisms of nonsyndromic craniofacial cleft formation could provide a better knowledge in cleft management and could be a possible basis for development and improvement of cleft treatment options. This study investigates the presence of BARX1, DLX4, FOXE1, HOXB3, and MSX2 positive cells by using immunohistochemistry in different types of cleft-affected tissue while determining their possible connection with cleft pathogenesis process.

Materials and methods: Craniofacial cleft tissue material was obtained during cleft-correcting surgery from patients with nonsyndromic craniofacial cleft diagnosis. Tissue material was gathered from patients who had unilateral cleft lip (n=36), bilateral cleft lip (n=13), and cleft palate (n=26). Control group (n=7) tissue material was received from individuals without any craniofacial clefts. The number of factor positive cells in the control group and patient group tissue was evaluated by using the semiquantitative counting method. Data was evaluated with the use of nonparametric statistical methods.

Results: Statistically significant differences were identified between the number of BARX1, FOXE1, HOXB3, and MSX2-containing cells in controls and cleft patient groups but no statistically significant difference was found for DLX4. Statistically significant correlations between the evaluated factors were also notified in cleft patient groups.

Conclusions: HOXB3 could be more associated with morphopathogenesis of unilateral cleft lip during postnatal course of the disorder. FOXE1 and BARX1 could be involved with both unilateral and bilateral cleft lip morphopathogenesis. The persistence of MSX2 in all evaluated cleft types could indicate its possible interaction within multiple cleft types. DLX4 most likely is not involved with postnatal cleft morphopathogenesis process.

The most common thoracic manifestation form of ankylosing spondylitis is apical fibrocystic changes. It is also known as apical fibrobullous disease (AFBD). The patient was diagnosed with ankylosing spondylitis before 9 years. He suffered COVID-19 infection and passed an intensive care period. However, post-covid fibrosis (PCF) atypically affected dominantly apical zones. If we had no sequential CT evaluations, our case could be easily confused with AFBD. On CT taken before COVID-19, the lung apex was normal. Thus, it was confirmed that there was no rheumatologic thoracic manifestation in the patient before suffering from COVID-19 pneumonia. PCF created similar changes as AFBD. Our case is the first reported paper on this topic.

Background: The effect of COVID-19 disease during pregnancy is still under investigation, however scientific studies have shown that pregnant women with COVID-19 infection are at increased risk for severe illness or complications [1]. Risk factors for severe disease and death in pregnancy include maternal age (especially ≥35 years), obesity, preexisting medical comorbidities (particularly hypertension and diabetes or more than one comorbidity), and being unvaccinated [2]. Many societies of obstetricians and gynecologists recommend that all pregnant patients undergo COVID-19 vaccination [1]. The aim of this study is to observe demographic characteristics, including education, place of residence and type of employment of women who chose to be vaccinated against COVID-19 in Lithuania, as well as to investigate any adverse reactions following the COVID-19 vaccine during pregnancy and compare the results to published scientific data.

Materials and methods: An online questionnaire for pregnant women primarily located in Lithuania who received at least one dose of COVID-19 vaccine before giving birth has been launched in July, 2021. Data were entered via Google Forms and analyzed using Microsoft Excel and IBM SPSS Statistics. Literature review was performed on PubMed and Google Scholar search engines on inclusion criteria: publication date 2019-2021, used keywords pregnancy, COVID-19, vaccination, side effects.

Results: Data were collected from 227 women vaccinated against COVID-19 during pregnancy. It was observed that the most chosen vaccine was Pfizer-BioNTech BNT162b2 (196 out of 227 individuals (86%)). More pregnant women confirmed having fever after the second dose compared to the first dose (p=0.006). In addition, injection site pain was the most common local side effect after both doses (98%) and more common after the first dose compared to the second (p=0.002). Regarding systemic reactogenicity more women experienced fatigue after the second dose comparing to the first dose (p=0.01). Furthermore, more women were unable to engage in daily activities after the second dose (p=0.03). All other symptoms did not differ after doses 1 and 2.

Conclusions: Overall findings of this study did not suggest any obvious safety signals among pregnant individuals who received COVID-19 vaccine and all the side effects were comparable to the general population. Completed literature review indicates that pregnant women vaccinated against COVID-19 experience the same side effects as individuals in general population and no specific postvaccination reactions among pregnant individuals are observed.

Background: An uncommon type of urinary calculus, Jackstone was named after its distinct resemblance to the children's game "Jacks." It typically involves the bladder and, to a lesser extent, the upper urinary tract.

Case presentation: Herein, we report a case of Jackstone vesical calculus in a 75-year-old male undergoing elective open prostate surgery for benign prostate hyperplasia refractory to medical treatment. Preoperative clinical examination revealed intermittent gross hematuria and symptoms suggestive of bladder outlet obstruction, while radiological investigation confirmed the presence of a solitary star-shaped spike-like bladder stone along with an overly enlarged prostate. Following open simple prostatectomy and concomitant intact stone removal, our patient made an uneventful postoperative recovery.

Conclusion: This case highlights an infrequent subtype of bladder lithiasis and further expands upon the importance of promptly treating the underlying cause once this rare entity is detected. A comprehensive review of the literature on Jackstone calculi is further presented.

Background: Vascular leiomyosarcoma is a rare but most common vascular tumor of the inferior vena cava.

Case presentation: We present the case of an incidentally diagnosed extraluminal leiomyosarcoma of the inferior vena cava in a 62 year old patient who presented with abdominal pain following blunt trauma. Ultrasonography showed a lobulated hypoechoic lesion in the upper abdomen. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a circumscribed lobulated near homogeneously enhancing retroperitoneal lesion in anterior relation to the infrarenal inferior vena cava, right paramedian in location with imperceptible vena caval lumen at the site of maximum contact. In positron emission tomography (PET) CT the lesion showed mild fluorodeoxyglucose (FDG) uptake with no distant metastases. CT guided biopsy with immunohistochemical analysis showed leiomyosarcoma. Patient underwent surgical resection with inferior vena cava reconstruction.

Conclusions: Leiomyosarcoma of the inferior vena cava is a rare tumor of vascular origin. Imaging plays an imperative role in the diagnosis and preoperative evaluation. This article also provides a comprehensive literature review of the radiological features of inferior vena caval leiomyosarcoma that would aid in optimal preoperative characterization and evaluation.

Autosomal dominant polycystic kidney disease (ADPKD) with concomitant horseshoe kidney is an extremely rare entity. In this case, we report a 45-year-old male patient with ADPKD and a horseshoe kidney who demonstrated hypertension, urological complications, and discomfort symptoms such as pain, breathing difficulties, and abdominal meteorism. After preoperative assessment and planning, the patient underwent nephrectomy. Bilateral nephrectomy without dividing the isthmus was performed successfully. The isthmus, which had complicated vasculature and was full of cysts, remained intact, avoiding severe bleeding and infection. The postoperative course was uneventful. Keeping the isthmus intact in such cases is a challenge for the surgeon. The rarity of polycystic horseshoe kidney in combination with the altered abdominal anatomy requires the proper preoperative strategy in order to avoid intraoperative complications.
