Assessment of fetal development during mid and late term pregnancies by standard B-Mode ultrasonography in Shetland ponies

Transrectal and transabdominal ultrasonography is an established method to monitor pregnancy, fetal growth and wellbeing in different species. Growth charts with multiple bio-morphometric parameters to estimate days of gestation and days before parturition exist in small companion animals, sheep and goats, riding type horses and large ponies but not in small horse breeds like Shetland ponies. The aim of this study was to apply fetal biometric assessment and detailed description of physiologic fetal development to mid and late term pregnancies in Shetland mares and to generate reference data for clinical practice and for future research. Fetal parameters were collected starting on day 101 of pregnancy in five Shetland mares. The fetal biometric parameters determined consisted of aortic diameter, eye diameter, combined rib and intercostal distance (CRID), stomach length and width and different heart morphology parameters in sagittal and frontal plane. Additionally, fetal activity and organ development in terms of differentiation and changes in echogenicity were recorded. Considering reliably assessable parameters, fetal CRID was the best predictor for gestational age with ± 13.6 days and fetal aortic diameter the most accurate for prediction of days until parturition with ± 16.2 days.

Comparison of fibroblast growth factor 19 concentrations between dogs with and without gallbladder mucoceles.

Fibroblast growth factor 19 (FGF19) is an enterohepatic hormone the synthesis of which is stimulated by bile acid activation of the nuclear farnesoid X receptor (FXR) in ileal enterocytes. Increased production of FGF19 downregulates hepatocyte bile acid synthesis and gluconeogenesis, while concurrently upregulating hepatocyte glycogenesis and gallbladder (GB) filling. The physiologic impact of this regulatory cycle is illustrated in cholecystectomized humans, in whom the disturbed meal-related flux of GB bile decreases serum FGF19 concentrations. Determine if serum FGF19 concentrations are lower in dogs with clinical GB mucoceles (GBMs) than in control dogs. Seven dogs with GBM diagnosed using abdominal ultrasonography, biochemical markers, and GB histopathology. Forty-two control dogs without gastrointestinal or hepatobiliary disorders also were evaluated. Health status of controls was assessed by physical examination and diagnostic hematologic and biochemical test results. Prospective cross-sectional study to compare fasting plasma or serum FGF19 concentrations between groups. Concentrations of FGF19 were quantified by a commercially available FGF19 ELISA. Concentrations of FGF19 were significantly lower in dogs with clinical GBM (median, 14.0 pg/mL; range, 12.8-67.2) than in control dogs (median, 145.3 pg/mL; range, 36.5-285.1). In dogs, GBM is associated with significantly decreased serum FGF19 concentrations. We speculate that this finding reflects compromised GB contraction and decreased enterohepatic circulation of bile flow. Subnormal FGF19 concentrations may influence bile acid synthesis and hepatic metabolism.

Does liver cirrhosis affect outcomes in non-metastatic esophageal squamous cell carcinoma (ESCC) undergoing radiotherapy-based treatment?

89 Background: Liver cirrhosis frequently coexists with esophageal squamous cell carcinoma (ESCC), as both conditions share alcohol consumption as a common etiological factor. Surgical intervention is often contraindicated or associated with significant morbidity in patients with non-metastatic ESCC and liver cirrhosis. Consequently, radiotherapy-based therapy is commonly employed. This study aims to investigate prognostic factors for overall survival in such patients undergoing radiotherapy-based therapy. Additionally, we will evaluate predictors for the 90-day mortality rate, proposed as a measure to mitigate treatment-related toxicity and prevent unwarranted or excessive medical interventions. Methods: From January 2001 to December 2021, we conducted a retrospective review of the medical records of 1298 patients diagnosed with esophageal squamous cell carcinoma (ESCC). Within this cohort, we identified 103 patients with concomitant liver cirrhosis, diagnosed through abdominal ultrasonography, computerized tomography, and/or liver biopsy, as appropriate. Of these individuals, 78 patients with non-metastatic ESCC and liver cirrhosis were included in our analysis. We collected clinicopathologic parameters and examined their correlation with overall survival and the 90-day mortality rate. Results: Univariate analysis revealed several factors significantly associated with inferior overall survival: Child-Pugh classification B/C (P<0.001, compared to A), radiotherapy alone (P=0.03, compared to chemoradiotherapy), prothrombin time prolonged by ≥2 seconds (P=0.024), albumin levels ≤3.5g/dl (P<0.001), controlled/refractory ascites (P=0.01, compared to no ascites), and total bilirubin levels ≥1.5mg/dl (P=0.004). In multivariate analyses, albumin levels ≤3.5g/dl (P=0.001, odds ratio: 2.500) and total bilirubin levels ≥1.5mg/dl (P=0.019, odds ratio: 2.012) were identified as independent prognostic factors. Among the 78 patients receiving radiotherapy-based therapy, the 90-day mortality rate was 10.3% (n=8). Clinical 8th AJCC stage IVA (P=0.02), clinical T classification T3/4 (P=0.049), prothrombin time prolonged by ≥4 seconds (P=0.009), and albumin levels ≤3.5g/dl (P=0.027) were significantly correlated with higher 90-day mortality rate. The logistic model indicated that albumin levels ≤3.5g/dl (P=0.015, odds ratio: 16.129) and clinical 8th AJCC stage IVA (P=0.012, odds ratio: 17.544) were independently associated with higher 90-day mortality rate. Conclusions: In patients undergoing radiotherapy-based therapy for non-metastatic esophageal squamous cell carcinoma (ESCC) and liver cirrhosis, pretreatment hypoalbuminemia has been associated with increased 90-day mortality and unfavorable prognosis.

Criptorquidismo unilateral abdominal em felino

During embryogenesis, the testes and ovaries form caudally to the kidneys. In males, the testes descend into the intrauterine scrotal sac. The absence of two testes in the scrotal sac after six months of age may indicate conditions such as testicular agenesis or cryptorchidism. In felines, cryptorchidism is rare (1-8%) compared to dogs (7-9%). Diagnosis involves anamnesis, palpation and abdominal ultrasonography, which is crucial in locating the testicle and planning for surgery. This case report describes a one-year-old male cat with unilateral abdominal cryptorchidism, which was successfully resolved through exploratory laparotomy and orchiectomy. The case highlights the importance of ultrasonography for the diagnosis and treatment of this condition.

Between-Visit Reproducibility of Shear Wave Viscoelastography in Volunteers and Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease.

To assess the reproducibility of six ultrasound (US)-determined shear wave (SW) viscoelastography parameters for assessment of mechanical properties of the liver in volunteers and patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease (MASLD) or metabolic dysfunction-associated steatohepatitis (MASH). This prospective, cross-sectional, institutional review board-approved study included 10 volunteers and 20 patients with MASLD or MASH who underwent liver US elastography twice, at least 2 weeks apart. SW speed (SWS), Young's modulus (E), shear modulus (G), SW attenuation (SWA), SW dispersion (SWD), and viscosity were computed from radiofrequency data recorded on a research US scanner. Linear mixed models were used to consider the sonographer on duty as a confounder. The reproducibility of measurements was assessed by intraclass correlation coefficient (ICC), coefficient of variation (CV), reproducibility coefficient (RDC), and Bland-Altman analyses. The sonographer performing the exam had no impact on viscoelastic parameters (P > .05). ICCs of SWS, E, G, SWA, SWD, and viscosity were, respectively, 0.89 (95% confidence intervals [CI]: 0.79-0.95), 0.81 (95% CI: 0.79-0.95), 0.90 (95% CI: 0.80-0.95), 0.96 (95% CI: 0.93-0.98), 0.78 (95% CI: 0.60-0.89), and 0.90 (95% CI: 0.80-0.95); CVs were 11.9, 23.3, 24.2, 10.1, 29.0, and 32.2%; RDCs were 33.0, 64.5, 66.9, 27.7, 80.3, and 89.2%, and Bland-Altman mean biases and 95% limits of agreement were -0.05 (-0.45, 0.35) m/s, -0.61 (-5.33, 4.10) kPa, -0.25 (-2.06, 1.56) kPa, -0.01 (-0.27, 0.26) Np/m/Hz, -0.09 (-7.09, 6.91) m/s/kHz, and -0.33 (-2.60, 1.94) Pa/s, between the two visits. US-determined viscoelastography parameters can be measured with high reproducibility and consistency between two visits 2 weeks apart on the same ultrasound machine.

The Role of Preoperative Abdominal Ultrasound in the Preparation of Patients Undergoing Primary Metabolic and Bariatric Surgery: A Machine Learning Algorithm on 4418 Patients’ Records

BackgroundThe utility of preoperative abdominal ultrasonography (US) in evaluating patients with obesity before metabolic bariatric surgery (MBS) remains ambiguously defined.MethodRetrospective analysis whereby patients were classified into four groups based on ultrasound results. Group 1 had normal findings. Group 2 had non-significant findings that did not affect the planned procedure. Group 3 required additional or follow-up surgeries without changing the surgical plan. Group 4, impacting the procedure, needed further investigations and was subdivided into 4A, delaying surgery for more assessments, and 4B, altering or canceling the procedure due to critical findings. Machine learning techniques were utilized to identify variables.ResultsFour thousand four hundred eighteen patients’ records were analyzed. Group 1 was 45.7%. Group 2, 35.7%; Group 3, 17.0%; Group 4, 1.5%, Group 4A, 0.8%; and Group 4B, 0.7%, where surgeries were either canceled (0.3%) or postponed (0.4%). The hyperparameter tuning process identified a Decision Tree classifier with a maximum tree depth of 7 as the most effective model. The model demonstrated high effectiveness in identifying patients who would benefit from preoperative ultrasound before MBS, with training and testing accuracies of 0.983 and 0.985. It also showed high precision (0.954), recall (0.962), F1 score (0.958), and an AUC of 0.976.ConclusionOur study found that preoperative ultrasound demonstrated clinical utility for a subset of patients undergoing metabolic bariatric surgery. Specifically, 15.9% of the cohort benefited from the identification of chronic calculous cholecystitis, leading to concomitant cholecystectomy. Additionally, surgery was postponed in 1.4% of the cases due to other findings. While these findings indicate a potential benefit in certain cases, further research, including a cost–benefit analysis, is necessary to fully evaluate routine preoperative ultrasound’s overall utility and economic impact in this patient population.Graphical

Evaluation of oral silymarin formulation efficacy in prevention of doxorubicin induced hepatotoxicity in patients with non-metastatic breast cancer.

Chemotherapy-induced hepatotoxicity is a common complication in breast cancer patients, especially with doxorubicin-containing regimens. Liver enzyme abnormality is reported in 34.8% of patients undergoing AC-T regimen and fatty liver is reported in 30% to 50% of cases. Antioxidant and anti-inflammatory properties of silymarin, a polyphenolic flavonoid extract derived from Silybum marianum, may be useful in preventing chemotherapy-induced hepatotoxicity. This study evaluated the effect of oral silymarin for preventing doxorubicin induced hepatotoxicity in non-metastatic breast cancer patients. In this triple-blind, placebo-controlled clinical trial, 50 patients with non-metastatic breast cancer were assigned to receive either 140 mg silymarin tablets or the placebo three times daily for 63 days and were evaluated for liver function test before the study and at the end of each chemotherapy cycle (every 3 weeks) for 4 cycles. In addition, an ultrasonography assessment was performed upon entry and the end of the study. Based on ultrasonography, the fatty liver grade was significantly higher in the placebo group at the end of the study. Moreover, the serum levels of aspartate aminotransferase (p = 0.015) and alkaline phosphatase (p = 0.004) at 6-week intervals, and the serum level of alkaline phosphatase (p = 0.002) at 9-week intervals were significantly lower in the silymarin group. Oral formulation of silymarin 420 mg/day for 63 days significantly prevented hepatotoxicity caused by doxorubicin in patients with non-metastatic breast cancer mostly based on liver ultrasonography but not laboratory parameters. Further investigations are suggested on different doses, durations and formulations of silymarin, particularly nano-formulations for increasing its oral bioavailability.

Metabolic dysfunction-associated steatotic liver disease (SLD) and alcohol-associated liver disease, but not SLD without metabolic dysfunction, are independently associated with new onset of chronic kidney disease during a 10-year follow-up period.

The new nomenclature of steatotic liver disease (SLD) including metabolic dysfunction-associated SLD (MASLD), MASLD and increased alcohol intake (MetALD), and alcohol-associated liver disease (ALD) has recently been proposed. We aimed to elucidate the relationship between each category of SLD and chronic kidney disease (CKD). We investigated the effects of various SLDs on the development of CKD, defined as estimated glomerular filtration rate (eGFR)<60mL/min/1.73m2 or positive for urinary protein, during a 10-year period in 12138 Japanese subjects (men/women, 7984/4154; mean age, 48years) who received annual health examinations including abdominal ultrasonography. The prevalences of SLD without metabolic dysfunction (SLD-MD[-]), MASLD, MetALD, and ALD were 1.7%, 26.3%, 4.9%, and 1.9%, respectively. During the follow-up period, 1963 subjects (16.2%) (men/women, 1374 [17.2%]/589 [14.2%]) had new onset of CKD. Multivariable Cox proportional hazard model analyses after adjustment of age, sex, eGFR, current smoking habit, diabetes mellitus, hypertension, and dyslipidemia showed that the hazard ratios (HR [95% confidence interval]) for the development of CKD in subjects with MASLD (1.20 [1.08-1.33], p=0.001) and those with ALD (1.41 [1.05-1.88], p=0.022), but not those with MetALD (1.11 [0.90-1.36], p=0.332), were significantly higher than the HR in subjects with non-SLD. Interestingly, subjects with SLD-MD[-] had a significantly lower HR (0.61 [0.39-0.96], p=0.034) than that in subjects with non-SLD. The addition of the novel classification of SLDs into traditional risk factors for the development of CKD significantly improved the discriminatory capacity. MASLD and ALD, but not SLD-MD[-], are independently associated with the development of CKD.

Can cereal-based oral contrast agents-assisted ultrasound become an alternative to non-contrast magnetic resonance imaging (MRI) in radiological follow-up for pancreatic cystic lesions?

Pancreatic cystic lesions (PCLs) are recommended to be examined by magnetic resonance imaging (MRI), yet MRI still has limitations, such as high costs, the risk of triggering claustrophobia, and relatively low availability compared with ultrasound. Oral contrast agents-assisted ultrasound has been used to examine the gallbladder and stomach, but whether oral contrast agents could improve the accuracy of transabdominal ultrasound (TAUS) for PCLs and could be a potential alternative to non-contrast MRI for PCL follow-up has not been studied. This study aimed to explore the value of cereal-based oral contrast agents in improving the accuracy of PCLs during TAUS. This is a prospective cohort study. Patients with PCL who were admitted to our center between January 2023 and January 2024 were enrolled, and TAUS was performed before and after taking cereal-based oral contrast agents. The imaging quality of the PCL was measured by structural visualization scores. The structural visualization scores of oral contrast agent-assisted ultrasound and non-contrast MRI were also compared. A total of 27 patients with PCLs were enrolled, and 30 PCLs were detected. The sonolucency of the PCL improved after oral contrast agent administration. Before taking the agent, only 30% of patients had satisfactory sonolucency; after taking the oral contrast agent, the corresponding proportion reached 80% (P=0.002). The structural visualization score of the PCL determined by oral contrast agent-assisted TAUS was higher than that determined without the aid of an agent [1 (0-6) vs. 1 (0-3), P=0.001], which was mainly reflected in the increase in the number of visible septa after taking the agent. No significant difference was detected between the structural visualization score of the PCL examined by oral contrast agent-assisted TAUS and that examined by non-contrast MRI and the correlation between the 2 types of scores were satisfactory [1 (0-6) vs. 2 (0-7), P=0.070, Spearman correlation factor r=0.880]. This study used a structured scoring system to confirm that cereal-based oral contrast agents could improve the ultrasound quality of PCLs, and the correlation between the quality of oral contrast agent-assisted ultrasound and non-contrast MRI findings on PCLs was satisfactory. Further research to improve visualization of PCLs on TAUS using oral contrast agents could result in TAUS being a potential alternative to MRI in the follow-up of PCLs in resource-limited situations.

Accuracy of the Measurement of Uterine Leiomyoma by Transabdominal Ultrasonography.

Introduction Uterine leiomyoma is a benign smooth muscle tumor. It does not necessarily require curative treatment, but if conservative management is chosen, it is important to rule out uterine leiomyosarcoma. When a size increase is observed, one must consider malignancy, and thus objective and cost-effective measurement of uterine size is important, especially for early detection of malignant change. Although MRI imaging is thought to be the gold standard for the diagnosis of uterine leiomyosarcoma, frequent MRI is impractical because of the incidence of uterine leiomyoma and the economic burden in real-world clinical practice. On the other hand, ultrasonography (US) is considered the most useful device in the observation of size changes. So this study aimed to examine the accuracy of the measurement of transabdominal US compared to MRI imaging. Materials and methods This retrospective study included 92 patients withuterine myoma ≥ 50 mm who undertook an MRI within 30 days after the transabdominal US. The longest diameter of the largest myoma (a), the longest diameter perpendicular to a in the sagittal image (b), and the longest diameter perpendicular to a and b in the axial image (c) were measured by US and MRI, and these were used to calculate the volume. Results were analyzed by intraclass correlation coefficient (ICC) 3.1. Results The ICC for the volume and major axis of the largest myoma by US and MRI were 0.87 and 0.90, respectively. The 95% confidence intervals (CI) were 0.82-0.91 and 0.87-0.93, respectively. Both reliability levels ranged from good to excellent. ICC was 0.54 (95%CI 0.15-0.78) in myomas with a volume of >500 cm3, and the concordant rate between US and MRI was poor to good. On the other hand, ICC was 0.82 (95%CI 0.57-0.93) even though all myomas with major axes greater than 120 mm had a volume >500 cm3, and the concordant rate between US and MRI measurements was moderate to excellent. In the evaluation by major axis, ICC was 0.60 (95%CI -0.41-0.95) for myomas larger than 160 mm, indicating a lower concordant rate. Conclusion Transabdominal US is an appropriate modality as well as MRI for follow-up of uterine myoma size if the nodules are 160 mm or smaller. Measurement of the major axis is easier and more useful than volume.

Megaureter in adults: a review of the current literature.

Megaureter (MU) is an uncommon condition in adults. The aim is to present a review of the current literature. A literature search was conducted to explore the current literature including case reports on MU in adults in the period 2003-2023. Each case was characterised in terms of the eight categories: sex, age, etiology, location, symptoms, diagnostic tool used, type of treatment and follow-up. There was no meta-analysis but two reviews. Total, 39 case reports were included based on 35 articles. The most common observations for the first four categories were male (sex), age below 40 (age), obstructed MU (etiology) and left-sided MU (location). Almost every patient appeared with symptoms, most frequently flank pain, abdominal pain and recurrent urinary tract infections. CT scan and transabdominal ultrasonography are the most commonly used diagnostic tools. Most cases underwent either laparoscopic or open surgical treatment with ureteral reimplantation as the most performed surgical procedure. A majority of the patients had an uneventful follow-up. MU in adults is a rare condition presenting with heterogeneous symptoms. CT scan and transabdominal ultrasonography should be used as diagnostic tools. Nearly all patients underwent surgical treatment with an uneventful follow-up. Complications such as stone formation and altered function of the affected kidney are common. Surgical treatment is recommended and is determined by consideration of age, symptoms, ureteral extension and progressive loss of renal function.

Ultrasound evaluation of scar thickness for prediction of uterine dehiscence in term women with previous caesarean sections.

To determine the role of ultrasound in evaluation of scar thickness for prediction of uterine dehiscence. This retrospective cross-sectional study was conducted in the Radiology department of Aga Khan University Hospital from 1st July to 31st December 2021 after approval from the University Ethic Committee. In this study pregnant women 18 to 40 years with a live singleton fetus with vertex presentation, at term, with history of prior caesarean section and availability of medical record were included. Using a curvilinear ultrasound transducer with optimally distended urinary bladder, the myometrial thickness was measured in the sagittal plane. The intraoperative visual findings of the lower uterine segment outcome at the time of C-section were recorded and categorized into two groups i.e., with and without dehiscence for statistical analysis. A total of 126 women were included. The mean age of the study participants was 29.8±4.1. The median gestational age was 35 (34-37) weeks. The highest AUC 0.58 was recorded for the scar thickness of ≤2.5mm with a sensitivity, specificity, PPV and NPV of 80.9%, 36.4%, 36.3% and 80.8% respectively. Similarly, the AUC for the scar thickness of ≤2mm was 0.55 with a sensitivity, specificity, PPV and NPV of 93%, 18.2%, 18.2% and 93% respectively. Transabdominal Sonography is a safe technique to determine the LUS thickness during antenatal ultrasound at term. A cutoff value of ≤2mm showed a high sensitivity and negative predictive value of 93% for evaluating the risk of uterine dehiscence.

Prevalence of Abnormal Cerebroplacental Ratio in Uncomplicated Full-term Pregnancy and Correlation with Adverse Perinatal Outcomes

Objective: To investigate the prevalence of abnormal cerebroplacental ratio (CPR) and predicting values for adverse perinatal outcomes in uncomplicated full-term pregnancies. Materials and Methods: This prospective cross-sectional study was conducted at Bhumibol Adulyadej Hospital, Royal Thai Air Force, Thailand between July and December 2023. The study population comprised pregnant women between the ages 18 and 45 presenting uncomplicated full-term pregnancies. Transabdominal ultrasonography in Doppler color mode was performed on all participants. Umbilical artery pulsatility index (UAPI) and middle cerebral artery pulsatility index (MCAPI) were both measured. CPR was calculated by MCAPI divided by UAPI. A CPR value was considered low if it was less than 1.03. Obstetric and perinatal outcomes were recorded including route of delivery, gestational age (GA) at delivery, obstetric complications, Apgar score, neonatal birth weight, neonatal intensive care unit (NICU) admission, and fetal non-reassuring tracing (FNR). Results: A total of 250 pregnant women were recruited. The mean maternal age and GA was 27.7 years, 39.6 weeks, respectively. Low CPR prevalence was recorded at 16.4 percent. There were 41 and 209 cases in low (&lt;1.03) and normal (≥1.03) CPR groups, respectively. UAPI and MCAPI of the normal/low CPR group were 0.8/1.3 and 1.1/0.9 with statistical significance. CPR for predicted value of FNR (1.03) gave sensitivity, specificity, PPV, and NPV at 95.5, 91.2, 51.2 and 99.5 percent, respectively. This study presented no adverse perinatal outcomes. Conclusion: Low CPR prevalence was 16.4 percent. Normal CPR values measured within a week before birth was a good indicator of normal perinatal outcomes.

Analysis of serum proteomic in cats with polycystic kidney disease-1 gene mutation

Feline autosomal dominant polycystic kidney disease (PKD) is common in Persian and Persian-cross cats. This study aims to investigate proteins that can be potential biomarkers for early disease diagnosis in cats with PKD1 heterozygous gene mutations and compare them with chronic kidney disease cats and normal wild-type cats. Thirty-three client-owned cats of variable breeds (ten PKD1 gene mutation cats, twelve wild-type cats with normal blood profiles, and eleven wild-type cats with chronic renal disease) were enrolled in this study. This study used serum-based proteomic profiling analysis in cats. Abdominal ultrasounds were examined in all cats. Proteomic analysis was conducted by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry and liquid chromatography-tandem mass spectrometry (LC-MS/MS). One hundred and fifty-nine proteins were significantly differentially expressed between each group. The proteins identified in this study are known to regulate the apoptosis pathway. The apoptosis regulator Bcl-2 (BCL2) was overexpressed in the chronic kidney disease (CKD) group, while apoptotic peptidase activating factor 1 (APAF1) and BCL2-associated X apoptosis regulator (BAX) were only expressed in the PKD group. Ingenuity pathway analysis revealed that proteins uniquely expressed in the PKD group were linked to the Wnt signaling pathway and MAPK pathway. Asparagine synthetase domain-containing and secreted frizzled-related proteins were interesting proteins that should be studied further for the possibility of a candidate protein for disease detection. The proteomic profiles identified in this study could be used as potential novel biomarkers for the early detection of PKD in cats.

Outcomes of Mechanical Resection of Endometrial Polyps and Submucosal Fibroids Through TruClear™ Hysteroscopy.

To assess the efficacy of mechanical resection through TruClear™ hysteroscopy in patients with endometrial polyps and submucosal fibroids. Descriptive study. Place and Duration of the Study: Department of Obstetrics and Gynaecology, Shifa International Hospital, Islamabad, Pakistan, from June 2018 to 2022. Patients diagnosed with endometrial polyps and submucosal fibroids confirmed by abdominal or transvaginal ultrasonography were included. Patients having a history of congestive cardiac failure, chronic kidney disease, and bleeding diathesis were excluded from the study. Data about the complete removal of pathology (endometrial polyps and submucosal fibroids), mean operating time, and postoperative complications such as bleeding and perforation were extracted. The follow-up was set up to 6 months after the procedure. The average age of the 45 patients was 35.62 ± 7.46 years. Heavy menstrual bleeding was the most prevalent symptom, seen in 73.3% of cases, followed by irregular vaginal bleeding (IVB) in 11.1% of cases. The most frequent disease identified by sonography was a polyp in 21 (47%) instances, followed by submucosal fibroids in 12 (27%) cases, mixed pathology in 10 (22%), and malignancy in 2 (4%) cases. The overall average operative time was 36.46 ± 24.94 minutes. A hundred percent removal of lesions was observed in this study. Persistent symptoms were observed in 13% of patients after the surgery so they were treated with other interventions. The most common intervention was an intrauterine hormonal device. Intraoperative bleeding was observed in only one patient and was managed by intraoperative intrauterine balloon insertion. The recurrence rate was 8.9% (4/45). TruClear™ hysteroscopy showed a major advantage in the successful and complete removal of the pathology, low operation time, and complications.

Novel method for assessing sinusoidal obstruction syndrome using four-dimensional computed tomography.

Todiagnose sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD), transabdominal ultrasonography is usually used to detect hemodynamic changes, but we tried to detect the changes using four-dimensional computed tomography (4D-CT). A 42-year-old Japanese woman was diagnosedwith late-onsetSOS/VOD with transabdominal ultrasonography and was also assessed using 4D-CT. Method We analyzed the portal vein (PV) contrast effect every 1.5seconds and plotted the values of the contrast effect. With this graph, we analyzedthreehemodynamic parameters. We found that these parameterscorrelatedwiththe patient's status and indicated stasis due to sinusoid constriction. 4D-CT may become a helpful tool to diagnose and follow up with SOS/VOD.

Hepatic Hydatid cyst in children: An experience from East of Turkey

İntoduction: Hydatid cyst is a parasitic disease caused by the infection of Echinococcus granulosus and rarely Echinococcus alveolaris eggs, which are endemic in our country. Current treatment options for liver hydatid cysts; They can be listed as medical treatment, surgical treatment, percutaneous drainage and clinical follow-up only. In this study, the effectiveness of the WHO-IWGE protocol in terms of diagnosis and treatment strategies in our pediatric cases of liver hydatid cyst in a health institution in eastern Turkey was evaluated in the light of the literature. Material Method: Pediatric patients between the ages of 0-16 who were diagnosed with KcKH and followed up and treated were evaluated retrospectively. In pre-operative evaluation, lung radiography, abdominal ultrasonography, serological tests, hemogram and liver function tests were routinely performed. Results: 250 child patients between the ages of 0 and 16, whose data were fully available, were included in the study. 118 of the cases were girls and 132 were boys. The average age was 11.2 years. Most of the KcKH patients were admitted to the hospital for another reason and the cyst was detected incidentally. Of the 65 patients requiring surgery, 17 were patients who initially underwent primary intervention with PAIR. Patients who underwent PAIR were observed for one night and discharged in an average of 18 hours. Patients with free drainage were discharged in 2-4 days. The average length of stay for patients who underwent open surgery was found to be 9 days. In conclusion; The Gharbi classification updated by WHO is effective and reliable in determining the KcKH treatment strategy. In cases who are receiving chemotherapy and an intervention decision is made, a final USG is performed just before the procedure; It can provide both a change in treatment management and more patients benefiting from medical treatment.

A case with an ectopic ejaculatory duct opening into the bladder trigone in Zinner syndrome, congenital unilateral renal agenesis, and an ipsilateral seminal vesicle cyst

IntroductionThis report describes a case with an ectopic ejaculatory duct opening into the bladder trigone in Zinner syndrome, congenital unilateral renal agenesis, and an ipsilateral seminal vesicle cyst.Case presentationThe patient was identified when no left kidney was detected in the fetal period. Abdominal ultrasonography and pelvic plain MRI at 6 months old revealed a 10‐mm cystic lesion on the dorsal aspect of the bladder. Cysto‐urethroscopy at 1 year old revealed a rather short posterior urethra and right and left inferior crests extending from the posterior urethra beyond the bladder neck. The ejaculatory duct opening was identified on the bladder trigone.ConclusionAnatomical abnormality of the ejaculatory duct may represent a cause of infertility and ejaculatory dysfunction in Zinner syndrome. Endoscopic evaluation should be performed for this rare anomaly, even in children.

Incidental discovery of unilateral hydronephrosis unveiling psoas major desmoid-type fibromatosis in a 24-year-old male: A case report with a 5-year follow-up.

Desmoid-type fibromatosis (DTF), also known as aggressive fibromatosis, is a rare neoplasm originating from the fascial or musculoaponeurotic tissues. While benign and characterized by slow growth, it exhibits local aggressiveness and lacks specific clinical characteristics. However, in a considerable percentage of patients, it could be asymptomatic and discovered by accident during routine clinical examinations. Only a few cases of DTF arising from the psoas major muscle have been reported in the medical literature. A 24-year-old male, asymptomatic and without significant personal or family medical history, was diagnosed with grade 2 hydronephrosis by abdominal ultrasonography during a routine physical examination. This diagnosis was made 15 days after undergoing uncomplicated open-heart surgery to repair an atrial septal defect. Intravenous pyelogram revealed hydronephrosis with dilation of the pelvicalyceal system. Ureteroscopy ruled out any intrinsic lesions of the ureter. Contrast-enhanced computed tomography identified a 3.5 × 2 × 5.2 cm mass in the retroperitoneum, closely associated with the psoas muscle and enveloping the ureter adjacent to the iliac artery. Postoperative pathological analysis confirmed a definitive diagnosis of sporadic DTF. The patient underwent exploratory abdominal surgery, during which the tumor was resected without any intraoperative complications. After close monitoring over a 5-year follow-up period, which included periodic physical examinations, magnetic resonance imaging, and ultrasonography, no local recurrence was detected. Achieving an accurate preoperative diagnosis presents a challenge in cases involving retroperitoneal tumors originating from the psoas major muscle and encasing the ureter. However, the insertion of a double J stent is deemed a crucial step in the surgical process, facilitating the dissection and isolation of the ureter from the tumor while preserving kidney function.

Adult patients with Laron syndrome tend to develop the metabolic syndrome

BackgroundThe metabolic Syndrome is the name of a cluster of abnormal clinical and metabolic states, which constitute a risk factor for diabetes and cardiovascular disease. AimTo determine whether adult patients with Laron Syndrome with excessive obesity develop the characteristics of the Metabolic Syndrome. SubjectsOut of a cohort of adult patients with Laron Syndrome followed in our clinic, records of 23 patients (12 females, 11 males) were found to have sufficient data for analysis. MethodsThe degree of obesity was determined by the measurement of subscapular skinfold thickness (SSFT), BMI and total body DEXA. NAFLD was determined by liver ultrasonography, serum lipids including adiponectin leptin, insulin and glucose were assessed by radioimmunoassay. ResultsBoth female and male patients were markedly obese with 59% and 39% fat of the total body mass respectively, as were total and LDL cholesterol, triglycerides and adiponectin. Some had developed NAFLD. They also suffered from insulin resistance and glucose intolerance. Eleven patients (3 females, 8 males) developed diabetes. All had varying degrees of hypertension. Eight subjects (3 females, 5 males) suffered from cardiovascular disease. One female died at aged 53 years, and two males died at ages 75 and 78 years. ConclusionWith advancing age and increasing obesity, adult patients with Laron Syndrome developed the characteristics of Metabolic Syndrome including diabetes and cardiovascular disease.
