Extranodal intraductal papilloma of the unilateral axillary supernumerary breast is a rare and unusual medical condition. This condition involves the development of a benign tumor, known as a papilloma, in the ducts of supernumerary breast tissue found in the axilla. We report a rare case of extranodal papilloma of an extranodal intraductal papilloma of a unilateral axillary supernumerary breast in a 70-year-old woman, who presented with a right axillary mass. The diagnosis was suspected on imaging and confirmed on anatomical examination. Surgical treatment with good post-treatment outcome.

Teratomas are the most prevalent type of germ cell tumors and usually display benign characteristics. Mature cystic teratomas consist of a varied mixture of mature tissue types that originate from squamous epithelium and skin adnexal structures. It is most commonly found in female gonads. A mature teratoma located in the abdomen of an adult male patient is exceptionally uncommon. In this case, we report a rare case of intra-abdominal mature cystic teratoma in an adult male.

Background: The long-term effects of extracorporeal shockwave therapy (ESWT) on rotator cuff repair are unknown. Objectives: To investigate the functional outcomes and structural changes of ESWT at 3-year follow-up after rotator cuff repair. Methods: A randomized clinical trial was conducted, including patients who underwent rotator cuff repair. The patients were assigned to two groups based on whether they underwent radial ESWT 3 months postoperatively. The ESWT Group received 5 weeks of rehabilitation and ESWT weekly, whereas the CONTROL Group received only rehabilitation. Visual analog scale (VAS) pain score and functional scores were analyzed at 3 months (baseline), 6 months, and 3 years follow-up. In addition, MRI and ultrasonography were used to assess tendon maturation, integrity, tendon quality, acromiohumeral distance (AHD), and muscle fatty infiltration. Results: Finally, 32 participants completed all the assessments. At the final follow-up, 2 patients in the ESWT Group (16.5 %) versus one patient in the CONTROL Group (6.25 %) had rotator cuff failure (P = 0.176). The ESWT treatment showed similar clinical outcomes in VAS-pain score, functional scores, tendon quality, AHD, and muscle fatty infiltration versus the CONTROL Group (Ps > 0.05). MRI analysis indicated improved tendon healing after ESWT treatment at both 6-month (P = 0.036) and 3-year follow-up (P = 0.028). Conclusion: Early intervention with radial ESWT sustained long-term effects on the healing of the repaired rotator cuff and similar functional outcomes at long-term follow-up compared with standard rehabilitation.

Joubert syndrome (JS) is a rare autosomal recessive disorder with brain stem and cerebellar malformations. Early diagnosis through Magnetic Resonance Imaging (MRI) and ultrasonography (US) is crucial for managing this condition. This report presents a JS case diagnosed at 24 weeks of pregnancy. A 25-year-old gravida 2, para 1 woman was referred at 24 weeks’ gestation for suspected posterior fossa abnormalities. Ultrasound revealed normal cerebellar hemispheres but significant abnormalities in the cerebellar vermis, including the molar tooth sign and polydactyly, suggesting JS. The fetal MRI confirmed these findings. Following specialist consultations, the patient opted to terminate the pregnancy. A stillborn female infant was delivered, and genomic DNA sequencing identified a frameshift deletion in the AHI1 gene. Early prenatal diagnosis of JS is crucial for informed pregnancy management. The combination of ultrasonography, MRI, and genomic DNA sequencing proved effective for diagnosis.

Objective: Puerperal uterine inversion is a rare and severe complication and is associated with short cord, uncontrolled cord traction, placenta accreta, or uterine atony. Case report: A primigravida woman gave birth a 2770 gm newborn at term at our hospital, and clinically presented postpartum hemorrhage, hypovolemic shock, postpartum preeclampsia and urinary retention. She discharged 3 days postpartum, but she complained persist vaginal bleeding and lower abdominal pain for more than 1 month. Uterine inversion was diagnosed and laparoscope surgery for reduction was done. Conclusion: The non-specific clinical presentation made diagnosis of uterine inversion more difficult. Except pelvic examination, sonographic and hysteroscopic images were record in this article. Surgical intervention was performed. A fundus incision was effective for reduction and had low risk of bladder and bowel injury.

Background: The anterolateral thigh (ALT) flap plays a crucial role in reconstructive surgeries, providing versatile and reliable soft-tissue coverage. Flap thickness is a critical determinant of tissue volume and quality. Vascular factors, including the vascular diameter of the perforators and the length of the vascular pedicle, significantly influence flap viability and postrepair outcomes. To enhance preoperative assessment, this study integrated gender and body mass index (BMI) to analyze the anatomical characteristics of ALT flaps. Methods: This study used somatic penetrating ultrasonography to examine bilateral ALT flaps in patients. This study analyzed the relationship between gender and ALT flap thickness, vascular diameter of the perforators, and vascular pedicle length. Chi-square test was used to assess variations in age and gender. Multiple t-tests compared flap thickness, vascular diameter, and pedicle length between men and women in different BMI groups. Results: A total of 158 patients were included in this study from January 2018 to December 2022. In BMI < 24 and BMI ≥ 24.0 groups, males had lower ALT flap thickness than females (p < 0.0001 in each subgroup). Similarly, the vascular diameter of the perforators followed the same trend, with females having larger vascular diameters than males in BMI < 24 and BMI ≥ 24.0 groups. In terms of vascular pedicle length, males had longer pedicle length than females in both BMI < 24 and BMI ≥ 24.0 groups (p < 0.05 in each subgroup). Conclusions: Females demonstrate greater ALT flap thickness and larger vascular diameter of the perforators than males, whereas males have a longer length of the vascular pedicle.

Intracranial hemorrhage (ICH) in pregnancy, estimated at 1 in 10,000 cases, presents significant diagnostic challenges prenatally despite advanced imaging techniques such as ultrasonography (US) and magnetic resonance imaging (MRI). Detecting ICH is crucial for pregnancy management and future treatment decisions aimed at improving fetal survival and reducing brain damage. This report presents the diagnosis and outcomes of 2 cases of prenatal ICH. The first case involves a 30-year-old pregnant woman with irregular prenatal care diagnosed with ICH at 32 weeks of gestation via US and MRI. She chose to continue the pregnancy, delivering a 3160 g male infant at 36 weeks via cesarean section. Following NICU care including resuscitation and ventriculoperitoneal shunt placement, the infant was discharged. Subsequent examinations showed a reduction in ventricle size. In the second case, a 27-year-old woman taking acenocoumarol for a mechanical heart valve developed fetal subdural hemorrhage detected by US and MRI. She opted to terminate the pregnancy, resulting in a stillborn male infant weighing 1530 g. Fetal ICH presents with varying severity and prognostic implications, diagnosed and graded using US. Fetal cranial MRI may help clarify the etiology. Management remains controversial, with termination of pregnancy potentially warranted in severe cases due to poor prognosis. Further research is needed to refine management and improve outcomes in fetal ICH.

Appendicitis is the most common cause of acute abdominal pain requiring surgical intervention; however, it is extremely rare in infants. Its diagnosis and treatment are challenging due to nonspecific clinical signs and symptoms. As a result, delayed or missed diagnosis is common in young children and is associated with an increased risk of perforation and peritonitis. We reported a case of a 4-month-old healthy male child. The patient presented with abdominal distention and fever. After ruling out other possible causes, he was diagnosed with acute appendicitis, which was confirmed by a CT scan. A gangrenous appendix, dilated bowel loops, and free fluid in the abdomen were discovered during surgery. An appendectomy was performed. The appendix in infants has an average length of 4.5 cm compared with 9.5 cm in adults. Infantile appendicitis is considered rare but cases have been documented also in neonates, misdiagnosis rates are high due to rarity in this age group in addition to nonspecific signs and symptoms, which led to a high perforation rate. Ultrasonography can diagnose appendicitis in children with a sensitivity and specificity of 90%-95% without subjecting the child to radiation. A physician should always keep the diagnosis of appendicitis in mind in the infant age group, even though it is rare, as a delay in diagnosis and treatment has been associated with an increased risk of complications including appendicular perforation and peritonitis.

Hydatid cyst is a zoonotic disease rarely involving the adrenal glands, even in areas where the disease is endemic. The purpose of this article is to present the clinical and imaging findings of adrenal hydatid cysts, along with a comprehensive literature review of related research. Here we report a rare case of an 18-year-old male with a right adrenal cystic lesion showing characteristic features of a hydatid cyst on ultrasonography and computed tomography, which turned out to be an adrenal hydatid cyst after surgical excision. In conclusion, when a cystic lesion is detected in the suprarenal regions, adrenal hydatid cysts should be considered in differential diagnosis, especially in patients who live in or have come from endemic areas. Medical imaging can play a crucial role in diagnosing, managing, and postsurgical assessment of this condition.

Introduction: Ultrasonography (US) features of papillary thyroid cancers (PTCs) are used to select nodules for biopsy due to their association with tumor behavior. However, the molecular biological mechanisms that lead to the characteristic US features of PTCs are largely unknown. Objectives: This study aimed to investigate the molecular biological mechanisms behind US features assessed by radiologists and three convolutional neural networks (CNN) through transcriptome analysis. Methods: Transcriptome data from 273 PTC tissue samples were generated and differentially expressed genes (DEGs) were identified according to US feature. Pathway enrichment analyses were also conducted by gene set enrichment analysis (GSEA) and ClusterProfiler according to assessments made by radiologists and three CNNs - CNN1 (ResNet50), CNN2 (ResNet101) and CNN3 (VGG16). Signature gene scores for PTCs were calculated by single-sample GSEA (ssGSEA). Results: Individual suspicious US features consistently suggested an upregulation of genes related to immune response and epithelial-mesenchymal transition (EMT). Likewise, PTCs assessed as positive by radiologists and three CNNs showed the coordinate enrichment of similar gene sets with abundant immune and stromal components. However, PTCs assessed as positive by radiologists had the highest number of DEGs, and those assessed as positive by CNN3 had more diverse DEGs and gene sets compared to CNN1 or CNN2. The percentage of PTCs assessed as positive or negative concordantly by radiologists and three CNNs was 85.6% (231/273) and 7.1% (3/273), respectively. Conclusion: US features assessed by radiologists and CNNs revealed molecular biologic features and tumor microenvironment in PTCs.

Female genital tract tuberculosis presents a diagnostic challenge because of its variable clinical presentation and radiological manifestation. Most patients are present with history of infertility, pain in the abdomen, vaginal discharge, and bleeding. These symptoms mimic those of gynecological cancer, such as endometrial carcinoma. Endometrial cancer typically manifests with vaginal bleeding in the post-menopausal age group; however, in less than 10% to 20% patients, it can occur in perimenopausal age groups, which makes it difficult to distinguish between malignancy and tuberculosis. We present a case report of a 40-year-old woman who complained of vaginal bleeding and lower abdominal pain. Her imaging findings favored the diagnosis of endometrial carcinoma but histopathology revealed tuberculosis.

Soft tissue myxomas are benign mesenchymal neoplasms typically found in the intramuscular components of the proximal extremities. However, soft tissue myxomas in the chest wall are rare. We report the case of a 41-year-old woman with soft tissue myxoma who presented with a slowly growing, palpable lump on her left anterior chest wall that has been present for several years. Mammography revealed an oval, circumscribed, and hyperdense mass in the retromammary fat layer of the upper inner quadrant of the left breast. Ultrasonography revealed an oval, circumscribed, and hypoechoic mass with internal echoes and multiple microcystic spaces. A triangular hyperechoic area adjacent to the pole of the mass and peripheral hyperechoic rim were also detected. The patient underwent surgical excision and was diagnosed with soft tissue myxoma with subcutaneous manifestation.

Purpose: Patients with lower urinary tract symptoms (LUTS) often experience comorbid depression and anxiety, yet the mechanisms underlying this association remain incompletely understood. This prospective study aimed to investigate the relationship between depression, anxiety, and LUTS in men. Materials and methods: A prospective study was conducted with 350 male patients who underwent urologic examinations at our institution from January 2021 to December 2021. Of these, 131 patients meeting the inclusion criteria were included. Various questionnaires, including the International Prostate Symptom Score (IPSS) and the Hospital Anxiety and Depression Scale (HADS), as well as LUTS examinations (prostate-specific antigen test, transrectal ultrasonography, and urine flowmetry), were administered. Results: Among the 350 patients, 131 were included in the analysis, with an average age of 58.0 ± 13.69 years. The total IPSS was 18.0 ± 8.69, with the average voiding symptom score at 8.7 ± 5.19 and the average storage symptom score at 6.0 ± 3.27. Both anxiety and depression were found to be correlated with LUTS (P

Persistent fetal vasculature, previously called persistent hyperplastic primary vitreous, is a rare congenital condition where a component of fetal vessels within the eye fails to regress, leading to visual acuity decrease or loss. We present a case of a 13-year-old male patient, with a history of second-degree consanguinity, psychomotor development retardation, intellectual deficit from birth, in addition to a progressive bilateral visual acuity decrease. He recently presented a leukocoria in the right eye. Ultrasound and MRI were performed showing a linear structure traversing the vitreous antero-posteriorly, in addition to a retinal detachment and lens luxation, suggestive of posterior persistent fetal vasculature. We draw attention to the late age at diagnosis due to the insidious evolution in our case, and we highlight the importance of ultrasound and MRI in establishing the diagnosis and identifying associated brain malformations.

Background: To enhance the accuracy of hepatocellular carcinoma (HCC) diagnosis using contrast-enhanced (CE) US, the American College of Radiology developed the CEUS Liver Imaging Reporting and Data System (LI-RADS). However, the system still exhibits limitations in distinguishing between HCC and non-HCC lesions. Purpose: To investigate the viability of employing machine learning methods based on quantitative parameters of contrast-enhanced ultrasound for distinguishing HCC within LR-M nodules. Materials and methods: This retrospective analysis was conducted on pre-treatment CEUS data from liver nodule patients across multiple centers between January 2013 and June 2022. Quantitative analysis was performed using CEUS images, and the machine learning diagnostic models based on quantitative parameters were utilized for the classification diagnosis of LR-M nodules. The performance of the model was assessed using the area under the receiver operating characteristic curve (AUC) and compared with the performance of four radiologists. Results: The training and internal testing datasets comprised 168 patients (median age, 53 years [IQR, 18 years]), while the external testing datasets from two other centers included 110 patients (median age, 54 years [IQR, 16 years]). In the internal independent test set, the top-performing Random Forest model achieved an AUC of 0.796 (95%CI: 0.729–0.853) for diagnosing HCC. This model exhibited a sensitivity of 0.752 (95%CI: 0.750–0.755) and a specificity of 0.761 (95%CI: 0.758–0.764), outperforming junior radiologists who achieved an AUC of 0.619 (95%CI: 0.543–0.691, p

Objective: This study aimed to verify whether pancreatic steatosis (PS) is an independent risk factor for type 2 diabetes mellitus (T2DM). We also developed and validated a deep learning model for the diagnosis of PS using ultrasonography (US) images based on histological classifications. Methods: In this retrospective study, we analysed data from 139 patients who underwent US imaging of the pancreas followed by pancreatic resection at our medical institution. Logistic regression analysis was employed to ascertain the independent predictors of T2DM. The diagnostic efficacy of the deep learning model for PS was assessed using receiver operating characteristic curve analysis and compared with traditional visual assessment methodology in US imaging. Results: The incidence rate of PS in the study cohort was 64.7 %. Logistic regression analysis revealed that age (P = 0.003) and the presence of PS (P = 0.048) were independent factors associated with T2DM. The deep learning model demonstrated robust diagnostic capabilities for PS, with areas under the curve of 0.901 and 0.837, sensitivities of 0.895 and 0.920, specificities of 0.700 and 0.765, accuracies of 0.814 and 0.857, and F1-scores of 0.850 and 0.885 for the training and validation cohorts, respectively. These metrics significantly outperformed those of conventional US imaging (P

Objective: The association between Papillary Thyroid Carcinoma (PTC) and coexistent Hashimoto’s Thyroiditis (HT) was controversial. The purpose of this study was to evaluate the presence of HT exerts any influence on the aggressiveness of PTC, and to establish a nomogram for predicting the possibility of aggressiveness in PTC. Methods: 373 consecutive PTC patients with/without coexistent HT from January 2017 to December 2020 were retrospective reviewed. Patients’ clinicopathologic and sonographic characteristics were collected for univariate and multivariate analyses. A nomogram was established based on the risk factors for aggressiveness in PTC. Results: Male (p = 0.001), tumor size >1.0 cm (p = 0.046) and lymph node metastasis (p = 0.018) were negatively associated with PTC coexisted with HT, while it was significantly positively associated with the frequence of multifocality (p = 0.010). Univariate and multivariate analyses suggested that age ≥55 years (p = 0.000), male (p = 0.027), HT (p = 0.017), tumor size >1.0 cm (p = 0.015), multifocality (p = 0.041), distance to capsular ≤0 cm (p = 0.050) and blood flow (Grade I: p = 0.044) were independent risk factors for predicting the aggressiveness in PTC. A nomogram according to these predictors was further developed and validated. The receiver operating characteristic curve (AUC = 0.734 and 0.809 for training and validation cohorts, respectively) and decision curve analyses indicated that the nomogram model was clinically useful. The calibration curve revealed that the nomogram exhibited an excellent consistency. Conclusions: In this study, the coexistent HT might play a protective role in preventing the proliferation of PTC. Dispensable aggressive treatment may be reduced in PTC by pre-operative identification of sonographic and clinical characteristics and incorporating with the predicted nomogram model.

The auspicious initiation of human reproduction starts by releasing the ovum through ovulation within the ovary. Ceaseless monitoring of the female reproductive organs has now become essential for combating fertility-related issues and for successful assisted reproduction. Cases of infertility and demands for assisted reproduction in our modern liberated society are rapidly increasing. External or Transvaginal ultrasound imaging of the ovary provides us with vital information about the number, size, and position of the follicles in the ovary and their cumulative response to biological stimuli. Manual screening of thousands of USG images having lacs of follicles is an extremely strenuous job and prone to humane error. This paper propounded a new deep-learning architecture named Double Contraction-UNet (DC-UNet) which makes follicle segmentation fully automatic. This model restructured the U-Net architecture by introducing two contracting paths to segment the follicular object with higher accuracy. The model was trained and tested on approximately forty two thousand annotated ovarian 2D ultrasonography images extracted from USOVA3D Training Set 1. The proposed model outperforms the other U-Net-based state-of-the-art models when trained and tested on the same dataset. The proposed model has achieved an accuracy rate of 97.82%, a precision rate of 97.54%, a Recall value of 94.34%, an F1 Score of 95.91%, a Dice Score of 0.76, and a Jaccard Similarity Index of 0.59.

Background: Although cerebral palsy is a risk factor for aspiration, there is insufficient research on residual gastric volume after preoperative fasting in children with cerebral palsy. We evaluated the incidence of a full stomach by ultrasound assessment of the gastric volume in children with cerebral palsy who underwent orthopedic surgery after preoperative fasting. Methods: The patients fasted for 8 h for solid foods and 2 h for clear liquids. We obtained the gastric antral cross-sectional area using ultrasound in the semi-recumbent and right lateral decubitus positions. A calculated stomach volume > 1.5 mL.kg−1 was considered as full, which poses a high aspiration risk. The primary outcome was the incidence of full stomach, and the secondary outcomes were the qualitative gastric volume, correlation of disease severity categorized according to the Gross Motor Function Classification System with the residual gastric volume, gastric volume per body weight, and qualitative gastric volume. Results: Thirty-seven pediatric patients with cerebral palsy, scheduled for elective orthopedic surgery, were included for analysis. Full-stomach status was observed in none, and the gastric volume per body weight was 0.5 (0.4–0.7) mL.kg−1. No significant differences were observed in the residual gastric volume (p = 0.114), gastric volume per body weight (p = 0.117), or qualitative grade of gastric volume (p = 0.642) in relation to disease severities. Conclusion: Children with cerebral palsy who fasted preoperatively had empty or nearly empty stomachs. Further studies are required to determine the optimal fasting duration for such children.

Background: In baseball, repetitive pitching leads to medial elbow injuries, particularly to the ulnar collateral ligament (UCL). To prevent pitchers from UCL injuries, it is important to quantify the response to elbow stress. Repetitive elbow external valgus torque and muscular fatigue induced by repetitive pitching could affect markers of the response, that is, humeroulnar joint gap and UCL morphology. The aims of the study were three-folded: to investigate the effect of (1) exerted handgrip force on the humeroulnar joint gap, (2) repetitive pitching on the humeroulnar joint gap and the UCL morphology, and (3) exerted handgrip force on the humeroulnar joint gap for different levels of elbow valgus stress is different after compared to before repetitive pitching in asymptomatic baseball pitchers. Methods: Medial elbow ultrasound images were collected in 15 asymptomatic male baseball pitchers. Three levels of static elbow valgus stress (0N, 50N, 100N) were applied with a TELOS device before and after repetitive pitching and with or without handgrip force. These images were used to assess the humeroulnar joint gap size and UCL length and thickness. After 110 fastball pitches or when 80% self-perceived fatigue on a VAS scale was reached, participants were instructed to stop throwing. Repeated measures ANOVAs were used to statistically test significant differences. Results: Handgrip force did not significantly affect the humeroulnar joint gap. The UCL thickness and length and the humeroulnar joint gap were also not different after compared to before repetitive pitching. While higher levels of applied valgus stress significantly increased the humeroulnar joint gap (P < .001), this effect was not significantly different in the interaction with handgrip force and repetitive pitching. Conclusion: The humeroulnar joint gap changes for different levels of elbow valgus stress. However, adult baseball pitchers did not respond to elbow stress after a single pitching session with or without submaximal handgrip force in the humeroulnar joint gap and UCL morphology.

Intussusception is one of the common conditions in children presenting with abdominal pain. The exact etiology of intussusception is unknown. Lead point is not identified in the majority of cases in children. Commonly, radiographic evidence suggests the presence of a target sign is diagnosis of intussusception. However, the presence of a double target sign in the case of intussusception is rare and depicts the presence of double intussusception. We present a case report of a 1-year-old child who presented to the emergency department with excessive crying for more than 10 hours. After the initial clinical assessment and acute management, an abdominal ultrasound revealed a double target sign on the sub-hepatic and left para-umbilical region which suggested double intussusception. No lead point was identified in our case. Early diagnosis and prompt treatment are the mainstay of management in such cases.

A 74-year-old man presented to the emergency department with the chief complaint of abdominal pain. A computed tomography scan showed paralytic ileus. An ileostomy tube was placed, but the symptoms of bowel obstruction did not improve. Two days after admission, the patient's renal function deteriorated. Transabdominal ultrasound (TUS) showed linear high-intensity echoes consistent with a fibrotic band and microbubbles suggestive of circulatory disturbance in the dilated intestinal tract. Subsequent contrast-enhanced ultrasound revealed circulatory disturbance of the small bowel wall. Emergency surgery was performed under the diagnosis of strangulated ileus. Intraoperative examination revealed that the terminal ileum was strangulated by a fibrotic band from the retroperitoneum, which was confirmed by TUS. The fibrotic band was resected, the strangulation was released, and ileocecal resection was performed. Postoperatively, intestinal peristalsis was rapidly restored. TUS was able to depict the fibrotic band, which could not be detected by a computed tomography scan, allowing the patient to undergo immediate surgical treatment. We herein report this case of strangulated bowel obstruction in which TUS and contrast-enhanced ultrasound were useful in preoperative assessment of the patient's condition.

Fetus-in-fetu (FIF) is a rare congenital anomaly in which a malformed parasitic twin develops within the body of a live fetus or child. Abdominal teratoma, a type of germ cell tumor, can be a great imaging mimicker of FIF and vice-versa, as they both can present as a heterogeneous mass with calcifications and a fat component. Radiological differentiation of these 2 entities should be made because of the difference in surgical planning and treatment options. Features such as visualization of distinct bony vertebral elements and encysted cystic components are the specific features of Fetus in fetu [1]. In contrast, the presence of elevated serum markers can help diagnose teratoma. Here, we report a case of a 5-month-old girl presented with progressive distension of the upper abdomen for the last 2 months, noticed by her mother. Her initial imaging with abdominal X-ray and ultrasonography showed the presence of a large heterogenous solid-cystic mass in the upper abdomen with large elongated calcifications. A provisional diagnosis of teratoma vs FIF was considered. CECT abdomen showed clear identification of osseous structures of the axial and appendicular skeleton within a fat density mass, along with an encapsulated cystic component, strongly suggestive of FIF. Her serum tumor markers were within normal limits. The final diagnosis of FIF was confirmed on Laparotomy and postoperative specimens.

Lymphoma is the most frequent hematologic malignancy that involves the breast. It represents less than 1% of all breast cancer. The most common subtype is the secondary B-cell lymphoma. Clinically, lymphomas are divided into primary and secondary breast lymphoma. We presented a case of 49-year-old female, who has diagnosed of Non-Hodgkin's Lymphoma, finalizing the treatment 2 months ago. Currently, she came for a check-up due to a palpable lump in the right breast. Mammography shows a dense, oval, and circumscribed mass. Ultrasound revealed a 3.6 cm oval, hypoechoic, lobulated mass with internal vascularity at color Doppler. Axillary nodes show cortical thickening of 7 mm, cortical blood flood, and absence of fatty hilum. The histopathology report corresponds to infiltration of the right breast and bilateral axillary nodes by Non-Hodgkin Lymphoma. This case corresponds with lymphoma recurrence manifested in breast. The diagnosis of lymphoma is an imaging challenge that simulates benign and malignant pathologies.

Objective: To address the limitations and challenges associated with transrectal (TR) biopsy and to present transperineal (TP) biopsy as a viable and potentially safer alternative to TR biopsy.Prostate cancer (PCa) is a significant global health concern. The prevalence of advanced-stage prostate cancer in Asia is higher than that in the United States, emphasizing the need for effective screening and diagnosis methods. The gold standard of diagnosis is a TR biopsy. However, it has limitations due to the risk of infection and potential complications, such as injury to the rectal artery. Efforts have been made to address issues such as false-negative biopsies, under-sampling, and over-sampling through MRI-guided biopsies. However, the TR approach makes it difficult to access the apical and anterior regions of the prostate. TP biopsy has emerged as an alternative to address the limitations of TR biopsy. Nevertheless, a TP biopsy is a painful procedure, requiring the use of general anesthesia and expensive equipment. As a result, it has been perceived as costly and time-consuming. In addition, it requires a steep learning curve. The introduction of local anesthesia such as pudendal nerve block and the adoption of freehand techniques have contributed to the feasibility of performing TP biopsy. Recent research indicates that freehand TP biopsy can yield comparable diagnostic results to template-guided approaches. The diagnostic performance, cancer detection rates, and complication rates of TP biopsy have demonstrated its potential as a safe and effective diagnostic method.

Background: With the widespread use of abdominal ultrasonography (US), incidental detection of common bile duct (CBD) dilatation is common in pediatric populations. This study investigated the causes and clinical significance of CBD dilatation in children without biliary symptoms, jaundice, or causative lesions in US. Methods: We retrospectively reviewed pediatric patients with CBD dilatation from July 2013 to June 2023. All cases were detected via abdominal US. We analyzed the patients’ clinical manifestations, laboratory data, diagnosis, underlying diseases, and clinical course. Results: In a total of 687 patients enrolled, 338 met inclusion criteria (90 in hepatobiliary, 248 in CBD dilatation group). Of 128 patients with incidental CBD dilatation who underwent regular US examinations, 91 (71.1%) experienced resolution during follow-up. The proportion of patients with intrahepatic duct dilatation was significantly higher in the non-resolution group (p = 0.038). General health examination group had significant smaller CBD diameter compared to the gastrointestinal and infection groups. Correlation analysis found starting point of resolution decline at 3.24 mm (all-inclusive) and 2.51 mm (infant group) CBD diameter. Conclusions: Most children with incidental CBD dilatation did not have abnormal hepatobiliary function or other sonographic abnormalities. They usually remained asymptomatic and experienced uneventful clinical courses.

A comprehensive understanding of a tumor is required for accurate diagnosis and effective treatment. However, currently, there is no single imaging modality that can provide sufficient information. Photoacoustic (PA) imaging is a hybrid imaging technique with high spatial resolution and detection sensitivity, which can be combined with ultrasound (US) imaging to provide both optical and acoustic contrast. Elastography can noninvasively map the elasticity distribution of biological tissue, which reflects pathological conditions. In this study, we incorporated PA elastography into a commercial US/PA imaging system to develop a tri-modality imaging system, which has been tested for tumor detection using four mice with different physiological conditions. The results show that this tri-modality imaging system can provide complementary information on acoustic, optical, and mechanical properties. The enabled visualization and dimension estimation of tumors can lead to a more comprehensive tissue characterization for diagnosis and treatment.

Su implantación en AP requiere una correcta formación de los profesionales. Abstract: Objective: The objective was to describe the characteristics of the use of clinical ultrasound in two health centers (SC) of Health Area VII of the Region of Murcia (CS Murcia-Sur and CS Floridablanca). Design: Observational, descriptive, longitudinal, prospective and multicenter study. Site: CS Murcia-Sur and CS Floridablanca (Health Area VII of the Region of Murcia). Participants: One hundred and thirty-five patients were included. Interventions: Performance of clinical ultrasound in the primary care (PC) consultation. Main measurements: Demographic variables (age, sex), as well as clinical variables (reason for consultation, type of ultrasound, results, referrals to the second hospital level, degree of diagnostic agreement) were collected. Results: One hundred and thirty-five patients were included, more than 50% were female. The main reason for consultation was musculoskeletal and soft tissue symptoms (44.4%), followed by digestive symptoms (21.5%). 44.4% of the ultrasounds were classified as normal, while pathological findings were found in 55.6%. Confirmatory tests were requested in 43.7% and the findings were confirmed in 67% of the patients. Conclusions: The use of ultrasound in PC allows to show the high prevalence of pathological findings in the examination of patients. In a technique that helps the clinician in his diagnostic-therapeutic process. The integration of clinical ultrasound in the PC consultation can save complementary studies and referrals to a second level of care. Its implementation in PC requires proper training of professionals.

Aim: To determine whether patients with chronic painful temporomandibular disorder (TMD) had abnormal diaphragm function compared to healthy controls and to explore the correlation between diaphragm contractility, psychological status, and pain characteristics. Methods: A single-blinded, case-control study was conducted involving 23 chronic painful TMD patients and 22 healthy volunteers. The examination and diagnosis were performed according to the Diagnostic Criteria for Temporomandibular Disorders, and questionnaires were used to evaluate pain, depression, anxiety, and physical symptoms status. B-mode ultrasound was used to measure diaphragm thickness and contractility. The sonographer responsible for measuring the diaphragm was blinded to group membership. Results: 1. Depression, anxiety, and physical symptoms scores were significantly higher in the patients than in the controls (p

Ultrasonography (USG) is a diagnostic imaging technique based on the application of ultrasound waves with a frequency greater than 20.000 Hz, corresponding to the upper limit of audible human sound. The frequencies used in ultrasound imaging typically range from 1 MHz to 16 MHz. The principles and applications of this type of waves were first described by the Curie brothers and despite the time that has passed, their use in dentistry has not currently become widespread. The generation of images in USG is the result of the relationship and behavior experienced by different bodies and structures before the application of ultrasound pulses. Ultrasound imaging and its different modes have been used in different areas of dentistry, surgery, and maxillofacial aesthetics, in the description of cysts and tumors, identification of caries, dental fractures or cracks, periodontal bone defects, maxillofacial fractures, temporomandibular disorders, evaluation of periodontal and peri‑implant tissues, in addition to the identification of anatomical structures in the facial region. Although USG in dentistry offers considerable advantages over other frequently used diagnostic imaging techniques, further research is still required in relation to the equipment used for the study of the maxillofacial area, the different tissues and anatomical spaces that are part of it.

Background: Meckel's diverticulum is one of the most common congenital malformations of the gastrointestinal tract. About three-fourths of Meckel's diverticulum are located in the distance ranging from 40 cm to 100 cm from the ileocecal valve. Most cases are lined with heterotopic mucosa (e.g., gastric, pancreatic, jejunal). Many cases are asymptomatic. Aim: This case report aims to present an ultrasound image for intussusception caused by the anatomical anomaly, namely Meckel's diverticulum. The article was written to integrate fundamental knowledge of anatomical variations or anomalies with clinical context. Case description: A 5-year-old girl previously diagnosed with obesity came to the hospital with severe abdominal pain. The abdomen, on palpation examination, was tender and painful. Diagnosis of intussusception was initially based on the history, clinical symptoms, and ultrasound imaging. The girl was finally qualified for surgery. During the procedure, the bowel invagination was performed, and Meckel's diverticulum was removed. The intestine was double-layered and intraoperatively confirmed intussusception with Meckel's diverticulum. Conclusions: Knowledge of anatomical anomalies is significant for practitioners. Meckel's diverticulum may be the cause of invagination intestines. CT or MRI is the test of choice when intussusception is suspected during a proliferative disease.

Objectives: Ectopic pregnancy is a crucial problem in Gynaecology. Previous studies concerning the medical treatment of ectopic pregnancies, have used only β-hCG (beta- human chorionic gonadotropin) values, to monitor the successful response to treatment. The current study was a PhD (Doctorate of Philosophy) thesis research, which has evaluated the vascularity indices’ changes. The values of vascularity indices could be used, in combination with β-hCG values and the gestational sac dimensions, in every medically treated ectopic pregnancy. The results could be used, for monitoring the course of all medically treated ectopic pregnancies. Study design: 72 women of reproductive age have taken part in the study. They have been admitted due to secondary amenorrhea, positive β-hCG test, with or without vaginal bleeding. The participants took part voluntarily and were allocated in two groups. The first group consisted of 37 women, who were possible normal or threatened intrauterine pregnancies (control group). The second group consisted of 35 women, whose sonographic findings suggested ectopic pregnancy, and qualified for methotrexate treatment (study group). Sonographic control and measurement of the vascularity indices (PI – RI) (Pulsatility index – Resistance index) of the ectopic pregnancy was conducted, in combination with β-hCG values for every admitted or outpatient woman.The dimensions of the gestational sac of both groups were measured during four consecutive periods of time. The control group has shown progressively increasing sac dimensions, whereas, in the study group sac dimensions were more stable or growing gradually smaller. The exception where those ectopic pregnancies that ruptured, which have also shown a gradual enlargement of the sac. Results: The endometrial thickness of the study group was gradually decreasing up to 76 % per day, and the more eminent, but not statistically significant decrease, was observed in the single dose regiment of methotrexate. Moreover, the quantitative PI and RI were evaluated, and the main finding was that there were no statistically significant decreases in any of the two groups. Concerning the study group, methotrexate treatment was successful, since there was a decrease of up to 80 %, whereas a clearly significant correlation was found between the β-hCG levels and the RI. Conclusion: The vascularity indices could be used safely, in combination with β-hCG levels and the decrease of the gestational sac dimensions, as criteria for the evaluation of response to medical treatment of ectopic pregnancies.

Objective: We devised a new dynamic assessment of the supraspinatus (DAS) using ultrasonography. The objectives of this study are as follows: 1. to verify the moving distance of the supraspinatus using ultrasonography in the cadaveric shoulders; 2. to evaluate the reliability of DAS in patients with rotator cuff tear (RCT) and investigate the correlation between DAS and magnetic resonance imaging (MRI) assessments. Methods: In Part 1, the supraspinatus in both shoulders of one cadaveric specimen was pulled laterally by 5 mm and 10 mm. In the ultrasonographic movie of the supraspinatus, the moving distances of a placed marker and a representative speckle which was visually identified as a high-intensity dot with the longest track were measured. In Part 2, among 62 RCT shoulders we verified the interrater agreement of DAS and correlation between DAS and MRI findings of RCT size and muscle atrophy. Results: In Part 1, during the supraspinatus traction, the moving distances of the marker and speckle were almost same; 1.07–2.68 mm and 1.60–2.67 mm, respectively (the pulled distance was 5 mm), 3.95–5.35 mm and 3.59–5.60 mm (the pulled distance was 10 mm). In Part 2, DAS showed a high interrater agreement of 0.74 in the kappa coefficients. DAS showed no correlations with tear size and atrophy, respectively (Spearman's rank correlation coefficient (ρ): 0.14 (p = 0.35) and 0.13 (p = 0.29)). Conclusion: DAS can reliably demonstrate dynamic aspects of the supraspinatus in RCT patients, which have been lacked in static imaging assessments as MRI.

Multiseptated gallbladder also known as “Honeycomb gallbladder” is a rare condition that was first described by Tandon in 1963. It is described as a congenital anomaly in most of the cases. It may be asymptomatic or may lead symptoms. We present the case of a multiseptate gallbladder in a 5 year old girl who was admitted for managament of acute appendicitis.

Parapelvic cyst (PPC) is a rare cyst that arises from the renal parenchyma and usually does not cause symptoms. However, PPC may cause compression of the pelvicalyceal system resulting in obstructive symptoms. Ultrasonography may not be sufficient to diagnose PPC since they are often misdiagnosed with hydronephrosis, thus computed tomography of the renal is required. In this case, we present, a 27 years old male with a 3 years history of partial urinary retention presented with intermittent loin pain. Hydronephrosis was found on ultrasonography but failed to identify the source of obstruction. A CT scan was conducted and a PPC was confirmed. Nephrostomy was scheduled for ureteral dilation and the patient responded well 4 months after surgery. In this case, we highlight the role of radiology in identifying and differentiating the PPC.

A Breus’ mole is a massive subchorionic thrombohematoma that arises below the chorionic plate on the fetal side of the placenta. It requires careful perinatal management because of the associated high incidence of severe fetal growth restriction and intrauterine fetal demise. However, the mechanism of its development remains unclear, and there are no reports examining the continuous changes in the hematomas. Herein, we report a case of a Breus’ mole in which ultrasonographic massive subchorionic thrombohematoma changes were observed during pregnancy. A 40-year-old pregnant patient presented with fetal growth restriction, a hematoma with a highly echoic lesion, and an extremely thickened placenta. The clinical picture of massive subchorionic thrombohematoma gradually changed from a high-echoic phase with a 7-cm thick placenta to a high- and low-echoic mixed phase to a completely low-echoic phase with a prominent atrophic placenta (placental thickness = 3.5 cm) in almost 8 weeks. At 34 weeks of gestation, a male infant was delivered via cesarean section due to its nonreassuring fetal status with extremely low birth weight (1230 g). Postpartum histological findings revealed the presence of a Breus’ mole. In conclusion, we observed the ultrasonographic changes of the massive subchorionic thrombohematoma that were detected as a placental hemorrhagic infarction by magnetic resonance imaging, from a high- to low-echoic area. The clinical course from massive subchorionic thrombohematoma to Breus’ mole may be a prominent atrophic change in the placental tissue during pregnancy. These sequential ultrasonographic findings could be a key factor in understanding the pathophysiology of Breus’ moles.

Background: Developmental dysplasia of the hip (DDH) is a common congenital disorder that may lead to hip dislocation and requires surgical intervention if left untreated. Ultrasonography is the preferred method for DDH screening; however, the lack of experienced operators impedes its application in universal neonatal screening. Methods: We developed a deep neural network tool to automatically register the five keypoints that mark important anatomical structures of the hip and provide a reference for measuring alpha and beta angles following Graf's guidelines, which is an ultrasound classification system for DDH in infants. Two-dimensional (2D) ultrasonography images were obtained from 986 neonates aged 0–6 months. A total of 2406 images from 921 patients were labeled with ground truth keypoints by senior orthopedists. Results: Our model demonstrated precise keypoint localization. The mean absolute error was approximately 1 mm, and the derived alpha angle measurement had a correlation coefficient of R = 0.89 between the model and ground truth. The model achieved an area under the receiver operating characteristic curve of 0.937 and 0.974 for classifying alpha

Introduction: Prenatal ovarian torsion (POT) is a clinical condition that has been described before, but is little known and up until now lacks clear guidelines on management. Prenatal discovery of an abdominal mass or cyst can lead to a lot of stress and anxiety with parents. Knowing that POT is a benign condition with marked sonographic-pathologic correlations, our aim is to define the clinical entity and radiological features of a POT with the largest population to date and set up clear guidelines on its management. Materials and methods: We retrospectively collected data from three different pediatric surgical units over a period of 10 years (between 2008-2018). All patients treated for POT were included. Postnatal radiological imaging as well as clinicopathological information was collected and correlated with our diagnostic criteria. Results: We recovered data from a total of 35 patients. A fluid-debris level on ultrasonography (US) was shown to be a specific feature of torsion and was present in all patients. All patients underwent laparoscopic resection of the cyst at a mean age of 73 days. Upon laparoscopy, 16 patients showed signs of adhesions to the cyst. Pathological findings showed the lack of any remaining ovarian tissue in all of the cases. Conclusions: Prenatal ovarian torsion is a condition with distinctive radiological features, the main being a fluid-debris level on sonography. Laparoscopic resection of the cyst has proven to be safe and should be considered in all patients diagnosed with POT.

Introduction: The placenta with the umbilical cord is a vital link between the mother and fetus. Umbilical cord supplies water, nutrients and oxygen from the mother to the fetus. The most unique character of the umbilical cord is its coiling, where the contents of the cord course in a coiled helical fashion. The umbilical coiling index(UCI) can be measured antenatally using ultrasonography. In the present study we have attempted to assess the UCI antenatally by ultrasound screening and correlate abnormal antenatal UCI with the adverse maternal and neonatal outcome of pregnancy. Aims: To study umbilical coiling index ultrasonographically and to correlate it with pregnancy outcome. Methodology: 150 antenatal cases in the second trimester of pregnancy between 22 and 28weeks of gestation attending the outpatient department were included for the study in a continuous manner and subjected to antenatal UCI measurement. The cases were followed up till delivery and various factors were noted. Results: We confirmed that maternal medical comorbidities ( gestational hypertension and anemia) have a significant correlation with abnormal umbilical cord coiling index, either hyper-coiling or hypo-coiling or both.Some studies have shown a particular adverse effect being manifested in both hypo and hypercoiling. In the present study significant correlation of abnormal coiling has been found with only anaemia and hypertension in pregnancy. The question, therefore, arises:“Does abnormal UCI have any significant role in prediction of adverse outcome in pregnancy or is it just a random association?” This study does not reflect any significant role of abnormal UCI in the prediction of adverse perinatal outcome. Hence efforts to monitor UCI in the antenatal period may not have any justification in the present scenario. The latest edition of William’s Obstetrics also makes a similar comment. A population based larger study to generate cut offs for hypo and hyper coiling and finding any association between abnormal coiling and perinatal outcome may throw more light on the utility of UCI as a predictor of adverse outcome in pregnancy.

Purpose: As common clinical screening tests cannot effectively predict a difficult airway, and unanticipated difficult laryngoscopy remains a challenge for physicians. We herein used ultrasound to develop some point-of-care predictors for difficult laryngoscopy. Methods: This prospective observational study included 502 patients who underwent laryngoscopy and a detailed sonographic assessment. Patients under 18 years old, or with maxillofacial deformities or fractures, limited mouth opening, limited neck movement or history of neck surgery were excluded from the study. Laryngoscopic views of all patients were scored and grouping using the modified Cormack-Lehane (CL) scoring system. The measurements acquired comprised tongue width, the longitudinal cross-sectional area of the tongue, tongue volume, the mandible-hyoid bone distance, the hyoid bone-glottis distance, the mandible-hyoid bone-glottis angle, the skin-thyrohyoid membrane distance, the glottis-superior edge of the thyroid cartilage distance (DGTC), the skin-hyoid bone distance, and the epiglottis midway-skin distance. ANOVA and Chi-square were used to compare differences between groups. Logistic regression was used to identify risk factors for difficult laryngoscopy and it was visualized by receiver operating characteristic curves and nomogram. R version 3.6.3 and SPSS version 26.0 were used for statistical analyses. Results: Difficult laryngoscopy was indicated in 49 patients (CL grade Ⅲ – Ⅳ) and easy laryngoscopy in 453 patients (CL grade Ⅰ – Ⅱ). The ultrasound-measured mandible-hyoid bone-glottis angle and DGTC significantly differed between the 2 groups (p

Background: Reduced lumbar lordosis may make the process of identifying the intervertebral distance easier. The primary aim of this study was to measure the L3...L4 intervertebral space in the same patients undergoing spinal anesthesia in three different sitting positions, including the classic sitting position (CSP), hamstring stretch position (HSP) and rider sitting position (RSP). The secondary aim was to compare ultrasonographic measurements of the depth of the ligamentum flavum and intrathecal space in these three defined positions. Methods: This study is a single-blinded, prospective, randomized study. Ninety patients were included in final analysis. the patients were positioned on the operating table in three different positions to perform ultrasonographic measurements of the spinal canal. The intervertebral distance (IVD), the distance between the skin and the ligamentum flavum (DBSLF) and the intrathecal space (IS) were measured in the L3...L4 intervertebral space in three different positions. Results: The RSP produced the largest mean distance between the spinous processes. The RSP yielded a significantly larger IVD than did the CSP (p < 0.001) and HSP (p < 0.001). The DBSP was larger in the CSP than in the HSP (p = 0.001). The DBSLF was significantly larger in the RSP than in the HSP (p = 0.009). Conclusions: Positioning the patient in the RSP significantly increased the intervertebral distance between L3...L4 vertebrae compared to the CSP and HSP, suggesting easier performance of lumbar neuraxial block.

Background: Brachial plexus block (BPB) has been accepted as a reliable alternative for general anesthesia in upper limb surgeries. Adding adjuvant drugs like dexmedetomidine and sufentanil has been shown to have clinical and pharmacologic advantages. In this randomized parallel clinical trial, we aim to compare the effects of these two adjuvants for bupivacaine in BPB. Methods: In this double-blinded study, by using computer-assisted block randomization, 40 patients ranged from 20 to 65 years old and scheduled for elective upper limb surgeries were assigned to two equal study groups (n = 20), receiving 1 mL of 5 ..g.mL-1 sufentanil (group S) or 1 mL of 100 ..g.mL-1 dexmedetomidine (group D) in adjunction to 30 mL of 0.5% bupivacaine for supraclavicular BPB under the guidance of ultrasonography. Characteristics of local anesthesia and postoperative analgesia were evaluated (n = 40). Results: The duration of blocks significantly improved in group S (sensory: estimated median difference (EMD) [95%CI] = 100.0 [70.0...130.0], p < 0.001; motor: EMD [95%CI] = 120.0 [100.0...130.0], p < 0.001). Group S also had significantly longer postoperative analgesia and lower opioid consumption within 24 hours after the surgery (EMD [95%CI] = 4.0 [3.0...7.0], p < 0.001; EMD [95%CI] = -5.0 [-5.0...-5.0], p < 0.001; respectively). None of the patients showed adverse effects concerning vital signs, nausea, or vomiting. Conclusion: Our study showed that during ultrasound-guided supraclavicular BPB, sufentanil is a fairly better choice than dexmedetomidine as an adjuvant for bupivacaine and can provide preferable sensory and motor blocks. No significant side effects were seen in either of the study groups.

An imperforate hymen is a rare malformation present at birth; however, in most cases, diagnosis is missed until adolescence, when hematocolpometra and its symptoms develop. At this stage, every further delay in diagnosis and treatment will negatively affect the quality of life of young females. It may also be one of the causes of endometriosis and its consequences, such as subfertility. Sonography of the pelvis and physical examination are the diagnostic modalities of choice for diagnosing hematocolpometra and imperforate hymen.We present a case of a 14-year-old patient admitted to the obstetrics and gynecology clinic with complaints of lower abdominal pain and urinary retention following dysuria. The patient was previously examined by a family doctor who misidentified the issue and treated it as a urinary infection. After the symptoms worsened, the patient was referred to a gynecologist. An ultrasound examination showed a distended vagina and uterus, suggesting hematocolpometra, and after further inspection, it was revealed to be caused by an imperforate hymen. A hymenectomy was performed, and about 900 mL of blood was drained. Symptoms and complaints ceased, and the patient was discharged the next day.

Background: The treatment for Achilles tendinopathy varies widely, and there is no consensus regarding the optimal treatment for both non-insertional and insertional Achilles tendinopathy. The purpose of this study was to evaluate the clinical efficacy of extracorporeal shock wave therapy (ESWT) in the treatment of insertional and non-insertional Achilles tendinopathy (AT). Methods: Sixty patients with AT were invited to participate in this study. Patients were allocated to one of two groups according to the site of the AT, including an insertional AT (IAT) group and a non-insertional AT (NIAT) group. ESWT was performed once a week for five weeks for both groups. The Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A) score and the visual analog scale (VAS) were used five times to evaluate the clinical outcomes, including before treatment, immediately after treatment, as well as one month, three months, and five years after treatment. Results: At three months after treatment, the IAT group exhibited a significantly higher VISA-A score (82 ± 6 vs. 76 ± 11; p = 0.01) and a significantly lower VAS score (1 ± 1 vs. 2 ± 1; p

Background: This study aimed to investigate the effect of high tibial osteotomy (HTO) on medial meniscus extrusion (MME) and the association between the changes in limb alignment and MME under weight-bearing (WB) conditions after HTO. Methods: We included 17 patients with knee osteoarthritis (OA) who underwent HTO. MME was evaluated using ultrasonography in supine and unipedal standing positions. Knee alignment was evaluated radiographically using WB, whole-leg radiographs with the hip-knee-ankle angle (HKAA), percentage of the mechanical axis (%MA), medial proximal tibial angle (MPTA), and joint line convergence angle (JLCA). All measurements were performed serially at four time points: preoperative and 3, 6, and 12 months postoperative. Clinical outcomes were assessed by knee injury and osteoarthrosis outcome score (KOOS) and visual analogue scale (VAS) value for pain. Results: Mean MME in the WB position was significantly greater than that in the supine position in the preoperative condition; however, MME in both supine and WB positions was significantly lowered postoperatively. The ΔMME, difference of MME between supine and WB positions, was significantly lowered postoperatively and maintained for up to 1 year. MME change in the WB position between preop and postoperative conditions was significantly correlated with change in HKAA and %MA at 1 year postoperative. KOOS and VAS score were significantly improved after HTO. Conclusions: HTO correcting varus alignment can decrease MME in WB position and minimise the change in MME between supine and WB positions. The changes in MME after HTO were correlated with changes in the mechanical alignments.

Essential thrombocythemia (ET) is associated with an increased risk of thrombosis and autoimmune renal involvement. We report an extremely rare case of an acute kidney injury (AKI) in the presence of bilateral renal pelvises fibrosis in a patient with a proven diagnosis of ET. A 48-year-old male patient with a past medical history of mild chronic kidney disease and ET was admitted to our hospital with AKI. The patient discontinued his hydroxyurea treatment for the past 2 months and laboratory data showed increasing serum creatinine levels and platelet counts with increased renal sizes, severe hydrocalyx, and bilateral renal sinuses’ fibrosis in imaging. The patient started again on hydroxyurea therapy and showed improvement in all laboratory scales. ET and increased levels of platelet-derived growth factors could cause renal sinuses fibrosis and glomerulopathy. In ET patients with renal sinuses’ fibrosis and glomerulopathy, initiating cytoreductive therapy could improve the outcome.

Twin pregnancies with a complete hydatidiform mole and a coexisting live fetus are rare. The incidence is estimated to be 1 in 20,000-100,000 pregnancies. Prenatal diagnosis can be made with ultrasound findings, abnormally elevated β-hCG levels, and fetal karyotype. There are various complications following these pregnancies which include hyperemesis gravidarum, vaginal bleeding, spontaneous abortion, pre-eclampsia, intrauterine growth retardation, preterm delivery, and persistent trophoblastic disease. We report an interesting case of twin pregnancy consisting of a complete hydatidiform mole and a normal fetus achieved with in-vitro fertilization in a primary infertile couple. Suspicion of molar pregnancy was made on ultrasound examination, but the couple refused other prenatal testing and wanted to continue the pregnancy. Although the pregnancy was at high risk because of the patient's age and complications associated with a molar pregnancy, a vigorous female baby was delivered at term. The purpose of this report is to present a case of a rare obstetric condition, give evidence that gestational trophoblastic disease is occurring more commonly in multiple gestations and in-vitro fertilization pregnancies, and highlight the importance of ultrasound in prenatal diagnostics and monitoring of high-risk pregnancies.

In an attempt to improvise the analgesia in patients with femoral fractures, we aimed at depositing local anesthetic deep to anterior psoas fascia (APf) under ultrasound (US) guidance to block lumbar plexus elements which emerge lateral, anterior, and medial to the psoas major muscle. We termed this as circumpsoas block (CPB). Clinical and computed tomography contrast studies revealed that a continuous CPB infusion with a catheter provided a reliable block of the lumbar plexus elements. No adverse were events noted. We conclude that US guided CPB is a reliable technique for managing postoperative pain after surgery of femur fractures.
