Review
Fetal MR imaging overcomes many of the technical barriers of ultrasound and is an important diagnostic tool for fetal genitourinary (GU) anomalies. It is suited for evaluation of GU anomalies because of the fluid-sensitive sequences and superior soft tissue contrast. Often GU malformations are part of a multisystem genetic or congenital condition, and imaging the entire fetus with MR adds additional clarity about the extent of disease. It adds confidence to diagnoses of renal agenesis, urinary tract dilation, cystic disease, and tumors. It is particularly useful to delineate anatomy in complex GU malformations. This additional information guides counseling.

OBJECTIVE
Endometrial biopsy (EB) is one of the most common gynecologic procedures. Office-based EB has replaced procedures involving general/loco-regional anesthesia and cervical dilatation, performed in the operating room[1,2,3]. The Grasp Biopsy seems to be the most appropriate EB technique for reproductive aged women[1,2,4]. Recently, the Visual D&C performed with hysteroscopic tissue removal devices has shown to be a valid alternative[5]. However, it is often difficult to obtain ad adequate specimen in peri/post-menopausal women with hypo/atrophic endometrium[2]. Our aim is to show a novel hysteroscopic EB technique called "Rail Biopsy" which requires widespread and cheap instruments.
SETTING
Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero-Universitaria di Bologna" Bologna, Italy.
PARTICIPANTS
women referred to our center for hysteroscopic endometrial biopsy.
INTERVENTIONS
We performed the "Rail Biopsy" technique with a 5.0 mm Continuous Flow Operative Hysteroscope with a 30° Lens and a 5Fr operative channel. We identify the endometrial target area (ETA) and we create a first track cutting through the endometrium in a caudo-cranial direction using cold scissors. We repeat the procedure creating a second parallel track, thus completing our "rail" and isolating a wide ETA. Then, in caudo-cranial direction, we cut through the stromal layer beneath the ETA. With a 5Fr cold grasping forceps, we clench the cranial edge of the ETA and we remove it from the uterine cavity. A high-quality specimen, even in case of hypo/atrophic endometrium or focal sessile lesions, can be obtained with this technique. The crucial aspect of the "Rail Biopsy" indeed is cutting through the stromal tissue, while the endometrium is minimally touched, avoiding thermal damage deriving from electrosurgery. The instruments required are widespread and cheap. Moreover, this technique can be performed on any wall of the uterus, under vision and, in the majority of patients, in an office-setting without cervical dilatation or general/loco-regional anesthesia, making it an attractive alternative to hysteroscopy performed in the operating room setting. Further studies comparing "Rail Biopsy" to other EB techniques are needed.
CONCLUSION
We showed a novel approach for hysteroscopic EB that may be particularly useful in patients with hypo/atrophic endometrium, easy to learn and with low costs.

Reactive oxygen species in skeletal muscle injury, fatigue, regeneration and ageing: In memory of John Faulkner The role of zinc and matrix metalloproteinases in myofibrillar protein degradation in critical illness myopathy.
Due to an unexpected activation of different zinc (Zn) transporters in a recent prospective clinical study, we have revisited the role of Zn homeostasis and the activation of matrix metalloproteinases (MMPs) in skeletal muscle exposed to the intensive care unit (ICU) condition (immobilization and mechanical ventilation). ICU patients exposed to 12 days ICU condition were followed longitudinally with six repeated muscle biopsies while they showed a progressive preferential myosin loss, i.e., the hallmark of Critical Illness Myopathy (CIM), in parallel with the activation of Zn-transporters. In this study, we have revisited the expression of Zn-transporters and the activation of MMPs in clinical as well as in experimental studies using an established ICU model. MMPs are a group Zn-dependent endopeptidases which do not only target and cleave extracellular proteins but also intracellular proteins including multiple sarcomeric proteins. MMP-9 is of specific interest since the hallmark of CIM, the preferential myosin loss, has also been reported in dilated cardiomyopathy and coupled to MMP-9 activation. Transcriptional activation of Zn-transporters was observed in both clinical and experimental studies as well as the activation of MMPs, in particular MMP-9, in various limb and respiratory muscles in response to long-term exposure to the ICU condition. The activation of Zn-transporters was paralleled by increased Zn levels in skeletal muscle which in turn showed a negative linear correlation with the preferential myosin loss associated with CIM, offering a potential intervention strategy. Thus, activation of Zn-transporters, increased intramuscular Zn levels, and activation of the Zn-dependent MMPs are forwarded as a probable mechanism involved in CIM pathophysiology. These effects were confirmed in different rat strains subjected to a model of CIM and exacerbated by old age. This is of specific interest since old age and muscle wasting are the two factors most strongly associated with ICU mortality.

Thoracic aortic aneurysms evolving within a type IIIb chronic aortic dissection are mostly treated with the deployment of an endograft. However, several cases of dissecting aneurysms are associated with a significant dilatation of the aortic arch. These cases are usually managed in two steps : arch reconstruction or supra-aortic trunk debranching at first and a secondary graft deployment for the descending thoracic aorta. We present through this case series an alternative approach for this severe condition which consists in the replacement of the thoracic aorta from its hemi-arch to the distal thoracic or visceral aorta using a left thoracotomy. We deliberately neglected the remaining dissecting aorta if its diameter was below 45 mm, hypothesizing its non evolution after repair. From 2012 to 2021, 9 patients have been treated for a thoracic aneurysm evolving after a IIIb chronic aortic dissection using a left thoracotomy and a 19°C circulatory arrest. Immediate postoperative results show no mortality nor neurological disorders and the 7 years follow up for all of these 9 cases enlightened the absence of aneurysmal evolution especially for the distal anastomosis and the remaining dissected aorta. This work suggests that this direct approach strategy can definitively treat a thoracic dissecting aneurysm unsuitable for a simple endovascular treatment.

INTRODUCTION AND IMPORTANCE
Hepatic round ligament necrosis is a rare condition that has atypical clinical presentation. Its diagnosis; however, being a combination of clinical and biological signs, is very dependent on the computed topography scan.
CASE PRESENTATION
This report demonstrates 2 cases that had different presentations. Case 1 was an elderly female with multiple comorbidities presenting with signs of sepsis, perturbation of liver enzymes and presence of thrombosis of portal vein as well as dilatation of bile ducts. On the other hand, case 2 was a younger male patient presenting with inflammatory syndrome, no other biological abnormalities and only an evident fatty stranding in his radiological workup.
CLINICAL DISCUSSION
Our 2 cases had different presentations in severity and were thus treated differently. The first patient had clinical, biological and radiological signs of severity; thus, he was treated surgically. On the other hand, the other patient with benign presentation was treated medically with antibiotics.
CONCLUSION
In the absence of recommendations concerning the management of hepatic round ligament necrosis, we suggest that treatment choice be based on the severity signs being: clinical, biological or radiological.

INTRODUCTION
Esophageal varices are dilated distal submucosal esophageal veins that connect the portal and systemic circulations. They are formed due to portal hypertension, which commonly resulted from cirrhosis. We presented an 8-year-old girl with esophageal varices without signs of cirrhosis. This case report aims to describe non-cirrhotic portal hypertension causing esophageal varices in a school-age girl.
PRESENTATION OF CASE
An 8-year-old girl presented with one month of progressive hematemesis. The patient had been diagnosed with esophageal varices since she was 6 years old. Liver function test was within normal limits, complete blood count revealed bicytopenia.
DISCUSSION
Due to well-preserved liver function, the patient underwent distal splenorenal shunt (DSRS). After the surgical procedure, the patient's clinical condition generally improved.
CONCLUSION
NCPH (non-cirrhotic portal hypertension) is treated similarly with cirrhotic portal hypertension. DSRS could be the treatment of choice for refractory esophageal varices.

Pupillary changes can be an important semiologic feature in focal epilepsy. Though the subcortical networks involving pupillomotor function have been described, cortical generators of pupillary dilation and constriction in humans are not well known. In this report, we describe a case of pupillary constriction occurring during seizures in a patient with drug resistant focal epilepsy. On stereoelectroencephalography, onset was noted within the posterior segment of the right intraparietal sulcus and direct cortical electrical stimulation of these electrode contacts reproduced pupillary constriction associated with habitual seizures. This is the first case report to describe ictal pupillary constriction during SEEG with confirmation of the cortical localization by direct cortical electrical stimulation. The posterior segment of the right intraparietal sulcus localization of pupillary constriction may aid in surgical evaluation patients with drug resistant focal epilepsy.

OBJECTIVE
To determine the diagnostic and therapeutic value of contrast-enhanced ultrasound-guided endoscopic retrograde appendicitis treatment (ERAT) in patients with uncomplicated appendicitis.
METHODS
A retrospective analysis was performed on clinical and ultrasound data collected from 105 pediatric patients with uncomplicated appendicitis between January 2020 and December 2023. The ultrasound findings before and after treatment, as well as postoperative follow-up and recurrence rates, were summarized and analyzed.
RESULTS
Successful intubation was achieved in 96 patients (91.4%). The conventional ultrasound appendix visualization rate was 39.6% (38/105), while the appendix visualization rate after contrast-enhanced ultrasound-guidance was 75% (72/105). Contrast-enhanced ultrasound revealed various appendiceal morphologic changes in 89 patients, such as twisting, tortuosity, stiffness, rough inner wall, dilated diameter, and narrowing of the lumen. Additionally, local filling defects, which indicated the presence of fecal stones or debris deposition, were noted in 68 patients. No leakage of the contrast agent occurred. Post-treatment evaluation showed improvement in appendiceal diameter, lumen, and filling defects (P < .01). The follow-up rate was 82 of 89 patients (92.1%), all of whom recovered well without a recurrence. The recurrence rate was 7.9% (7/89). Among the patients with recurrences, five patients resolved after medical treatment and two patients recovered after surgical treatment.
CONCLUSION
Contrast-enhanced ultrasound-guided ERAT for uncomplicated appendicitis is safe and effective. Specifically, the appendix is increased, which facilitates an evaluation of therapeutic effectiveness. ERAT serves as a valuable supplementary modality to determine the need for surgical treatment of acute appendicitis, which is of significant clinical value.

Genetic testing is the gold standard for diagnosing different epidermolysis bullosa (EB) subtypes; however, testing rates are low. We conducted a pilot study to test feasibility of a novel, home-based registry that involved patients with EB submitting self-reported clinical symptoms using secure, online surveys (REDCap) and submitting buccal swabs for exome sequencing of EB-related genes (GeneDx). In total, 50 EB participants were enrolled, with an average age of 17 years and an average distance of 198 miles from EB specialty centers. All buccal swabs (N = 24) provided sufficient DNA for sequencing without causing mucosal trauma and 80% of participants were found to have pathogenic variants in COL7A1, the gene mutated in DEB. Participants with recessive dystrophic EB (RDEB) reported a higher prevalence of esophageal dilations (65.7% vs. 0%, p = .009) and mitten deformities of the feet (57.1% vs. 0%, p = .047) compared to non-RDEB participants.

Journal of Cosmetic Dermatology Jun 2024To assess the effectiveness and safety of treating erythematotelangiectatic rosacea using fractional radiofrequency (FRF).
OBJECTIVE
To assess the effectiveness and safety of treating erythematotelangiectatic rosacea using fractional radiofrequency (FRF).
METHODS
Twenty patients with a confirmed diagnosis of erythema capillaris rosacea were selected, and one side of each patient's face was randomly assigned to receive FRF treatments for three to six times, with an interval of 2 weeks between each treatment. VISIA, dermoscopy, and the Clinician's Erythema Evaluation Scale (CEA) were applied to evaluate the efficacy of the treatment before and after the treatment, to record the VAS scores and adverse reactions, and to conduct a patient satisfaction survey.
RESULTS
The characteristic counts and scores of red zone and porphyrin as assessed by VISIA test were significantly decreased, and the difference between the treated side and the pretreatment side was statistically significant (p < 0.05), and the efficacy of the treatment was statistically insignificant compared with the control side, except for the red zone and porphyrin which were statistically significant before and after the treatment (p > 0.05). By CEA score, the difference between the treated side after treatment and the control side was statistically significant (p < 0.05), and the difference between the treated side before and after treatment was statistically significant (p < 0.05); the difference between the control side before and after treatment was not statistically significant (p > 0.05). Dermatoscopic observation showed reduction in pore size, reduction of yellowish-white and black horn plugs within the pores, lightening of the red background and thinning and blurring of the capillary structure on the treated side of the skin compared to the control side, and the skin on the treated side showed the above mentioned changes before and after the treatment as well. The mean pain score of the subjects was obtained by VAS score 3.67 ± 0.90. Adverse effects included mild edema, erythema, and microscopic crusting; no long-term adverse effects were seen in all patients. The efficacy of FRF treatment was evaluated 1 month after the final treatment, and 85% of the subjects rated it as satisfactory, very satisfactory, and very satisfactory.
CONCLUSION
FRF for the treatment of erythematous capillary dilatation rosacea is effective, safe, and suitable for clinical promotion.
