This study aimed to evaluate the impact of shear stress on surgery-related sacral pressure injury (PI) after laparoscopic colorectal surgery performed in the lithotomy position. We included 37 patients who underwent this procedure between November 2021 and October 2022. The primary outcome was average horizontal shear stress caused by the rotation of the operating table during the operation, and the secondary outcome was interface pressure over time. Sensors were used to measure shear stress and interface pressure in the sacral region. Patients were divided into two groups according to the presence or absence of PI. PI had an incidence of 32.4%, and the primary outcome, average horizontal shear stress, was significantly higher in the PI group than in the no-PI group. The interface pressure increased over time in both groups. At 120 min, the interface pressure was two times higher in the PI group than in the no-PI group (PI group, 221.5 mmHg; no-PI group, 86.0 mmHg; p < 0.01). This study suggested that shear stress resulting from rotation of the operating table in the sacral region by laparoscopic colorectal surgery performed in the lithotomy position is the cause of PI. These results should contribute to the prevention of PI.

INTRODUCTION
Adult sacrococcygeal teratoma (SCT) is a rare disease that is not easily detected or easily missed, and its treatment is based on surgery, including transabdominal, transsacral, or a combination of both, but there are no clear guidelines for diagnosis and treatment. We share a case of Altman type III SCT in order to provide more reference protocols for the diagnosis and treatment of adult SCT, and more importantly to increase our understanding of different types of SCT cases in adults.
PATIENT CONCERNS
Our patient was a 31-year-old adult woman who underwent complete surgical resection of a cystic mature teratoma of the right ovary 8 years ago and is currently 13 months postpartum without menstruation, usually with a feeling of anal bulge, with symptoms such as constipation.
DIAGNOSIS
We diagnosed SCT by vaginal ultrasonography, computed tomography and magnetic resonance imaging (MRI); benign tumors were considered in the results of serum tumor markers.
INTERVENTIONS
We chose the surgical approach of laparoscopic transabdominal-sacrococcygeal approach to completely remove the patient SCT and coccyx.
OUTCOMES
The location of SCT is concealed and the clinical symptoms are not obvious. Vaginal ultrasonography, CT and MRI can not only improve the diagnostic rate of SCT, but also understand the size and mass of SCT, providing an exact basis for clinicians to select the laparoscopic transabdominal-sacrococcygeal approach.
CONCLUSION
Our sharing increases the reports of rare cases of teratoma with the same histological findings in different organ tissues of the same patient at different times, whether this occurs incidentally requires more case reports and further basic research; in addition, the laparoscopic transabdominal-sacrococcygeal approach is a safe and effective surgical approach for the treatment of Altman type III SCT in adults; finally, this case reminds us that SCT may not affect pregnancy and pregnancy outcomes and provides a reference for the selection of interventions for SCT with pregnancy.

BACKGROUND AND AIM
The use of ultrasound has immensely increased the safety toward regional blocks and central venous access and has been considered as the standard of care for securing central access. The aim of this study is to estimate the prevalence of occult spinal dysraphism using ultrasound in children less than 2 years of age undergoing elective urogenital or anorectal surgery.
MATERIAL AND METHODS
The lumbosacral region of 159 American Society of Anesthesiologists (ASA) category I/II patients, posted for elective urogenital and anorectal surgery was scanned with ultrasound, prior to giving caudal block.
RESULTS
The prevalence of occult spina bifida was 3% in our study. There was no statistically significant association of cutaneous marker with abnormal scan.
CONCLUSION
Prevalence of occult spina bifida was ten-times higher in our study than in the general population. Perioperative ultrasound screening of the lower spinal anatomy by anesthesiologist done prior to performing neuraxial block is worthwhile in ruling out occult spinal anomalies in high-risk children of occult spinal dysraphism.

KEY CLINICAL MESSAGE
Plasma cell myeloma is a rare entity in the pediatric population. The peak incidence is in the seventh decade, with less than 2% of cases occurring in patients under the age of 40. It is worth noting that any destructive bony lesion in a child should be investigated.
ABSTRACT
Plasma cell myeloma (multiple myeloma) is the most common form of plasma cell neoplasm. It is a rare entity in young patients. The peak incidence is in the seventh decade, with less than 2% of cases occurring in patients under the age of 40. A male patient aged 9 years old with a progressive pain in lower back for about 1 month, aggravated by bending, associated with inability to stand upright, no any history of trauma. He complained about left pin-point chest pain, no any history of febrile illness. MRI showed a mass lesion of the L3 vertebra; CT scan revealed osteolytic lesions in the left T12, S2-sacral region, and left calvarium. Histology report of L3 lesion revealed cells with an eccentric nucleus, prominent Golgi apparatus and Flow cytometry revealed cells stained positive for CD 138 and CD56 and negative for CD45 expression. In situ hybridization identified k-light chain band restriction. Bone marrow evaluation was normal. A small serum monoclonal immunoglobin A spike of k-light chain type was noted. Other tests like complete blood count, lactate dehydrogenase levels, renal functional tests, and B2-microglobulin were normal. A diagnosis of plasma cell myeloma was made and the patient was started on emergent radiation to L3 lesion due to progressive neurological symptoms followed systemic therapy which resulted int reduction of L3 lesion. Plasma cell myeloma is extremely rare form of liquid tumor in the pediatric population, and it is important for any destructive bony lesion in a child to have appropriate work up.

Vestibulodynia is a complex pain disorder characterized by chronic discomfort in the vulvar region, often accompanied by tactile allodynia and spontaneous pain. In patients a depressive behaviour is also observed. In this study, we have used a model of vestibulodynia induced by complete Freund's adjuvant (CFA) focusing our investigation on the spinal cord neurons and microglia. We investigated tactile allodynia, spontaneous pain, and depressive-like behavior as key behavioral markers of vestibulodynia. In addition, we conducted in vivo electrophysiological recordings to provide, for the first time to our knowledge, the characterization of the spinal sacral neuronal activity in the L6-S1 dorsal horn of the spinal cord. Furthermore, we examined microglia activation in the L6-S1 dorsal horn using immunofluorescence, unveiling hypertrophic phenotypes indicative of neuroinflammation in the spinal cord. This represents a novel insight into the role of microglia in vestibulodynia pathology. To address the therapeutic aspect, we employed pharmacological interventions using GABApentin, amitriptyline, and PeaPol. Remarkably, all three drugs, also used in clinic, showed efficacy in alleviating tactile allodynia and depressive-like behavior. Concurrently, we also observed a normalization of the altered neuronal firing and a reduction of microglia hypertrophic phenotypes. In conclusion, our study provides a comprehensive understanding of the CFA-induced model of vestibulodynia, encompassing behavioral, neurophysiological and neuroinflammatory aspects. These data pave the way to investigate spinal cord first pain plasticity in vestibulodynia.

The evaluation of the lumbopelvic region is a crucial point during postural assessment in childhood and adolescence. Photogrammetry (PG) and Spinal Mouse (SM) are two of the most debated tools to properly analyze postural alignment and avoid misleading data. This study aims to find out the best linear regression model that could relate the analytic measurements of the SM with one or more PG parameters in adolescents with kyphotic postures. Thirty-nine adolescents (female = 35.9%) with structural and non-structural kyphosis were analyzed (13.2 ± 1.8 years; 1.59 ± 0.12 m; 47.6 ± 11.8 kg) using the SM and PG on the sagittal plane in a standing and forward-bending position, allowing for the measurement of body vertical inclination, lumbar and pelvic alignment, trunk flexion, sacral inclination during bending, and hip position during bending. Lordosis lumbar angles (SM) were significantly (r = -0.379, r = -0.328) correlated with the SIPS-SIAS angle (PG) during upright standing, while in the bending position, the highest correlation appeared among the sacral-hip (SM) and the sacral tangent (ST_PG; r = -0.72) angles. The stepwise backward procedure was assessed to estimate the SM variability in the bending and standing positions. Only in the bending position did the linear regression model reach high goodness-of-fit values with two regressors (ST_PG η2=0.504, BMI η2=0.252; =0.558, < 0.001, CCC = 0.972, r = 0.763). Despite gold-standard methods reducing error evaluation, physicians and kinesiologists may consider photogrammetry as a good method for spinal curve prediction.

INTRODUCTION AND IMPORTANCE
Supernumerary ribs are very rare. They may occur at any level of the spine. We present here a case of an unusual localization of an extra rib that has not been previously described in the literature.
CASE PRESENTATION
A 4-year-old girl, with no medical history, presented with a congenital deformity in the sternal region mimicking a tail. The tail-like structure had a bony axis and was covered by normal skin and hairs. A computed tomography of the chest demonstrated that this structure was an abnormal bone articulated with the the sternum. For cosmetic purposes, we have decided to resect the malformation. On histopathological examination, it was a supernumerary rib.
CLINICAL DISCUSSION
A review of the literature reveals a global incidence of cervical ribs ranging from 0.04 % up to 4.5 %, intrathoracic ribs in about 50 cases to date and very few reports on supernumerary ribs in the lumbar and sacral region. We were unable to find any similar cases of supernumerary ribs in the sternum.
CONCLUSION
Supernumerary ribs are rare and benign congenital anomalies. This case report describes an unusual localization of an extra rib in the sternum mimicking a tail.

BACKGROUND
Laparoscopic rectal cancer radical surgery is a complex procedure affected by various factors. However, the existing literature lacks standardized parameters for the pelvic region and soft tissues, which hampers the establishment of consistent conclusions.
AIM
To comprehensively assess 16 pelvic and 7 soft tissue parameters through computerized tomography (CT)-based three-dimensional (3D) reconstruction, providing a strong theoretical basis to address challenges in laparoscopic rectal cancer radical surgery.
METHODS
We analyzed data from 218 patients who underwent radical laparoscopic surgery for rectal cancer, and utilized CT data for 3D pelvic reconstruction. Specific anatomical points were carefully marked and measured using advanced 3D modeling software. To analyze the pelvic and soft tissue parameters, we employed statistical methods including paired sample -tests, Wilcoxon rank-sum tests, and correlation analysis.
RESULTS
The investigation highlighted significant sex disparities in 14 pelvic bone parameters and 3 soft tissue parameters. Males demonstrated larger measurements in pelvic depth and overall curvature, smaller measurements in pelvic width, a larger mesorectal fat area, and a larger anterior-posterior abdominal diameter. By contrast, females exhibited wider pelvises, shallower depth, smaller overall curvature, and an increased amount of subcutaneous fat tissue. However, there were no significant sex differences observed in certain parameters such as sacral curvature height, superior pubococcygeal diameter, rectal area, visceral fat area, waist circumference, and transverse abdominal diameter.
CONCLUSION
The reconstruction of 3D CT data enabled accurate pelvic measurements, revealing significant sex differences in both pelvic and soft tissue parameters. This study design offer potential in predicting surgical difficulties and creating personalized surgical plans for male rectal cancer patients with a potentially "difficult pelvis", ultimately improving surgical outcomes. Further research and utilization of these parameters could lead to enhanced surgical methods and patient care in laparoscopic rectal cancer radical surgery.

Ewing sarcoma is the second most frequent primary bone tumour of childhood and adolescence. The aim of this report is to describe the imaging, pathology, clinical findings, and treatment of a primary intradural extramedullary Ewing sarcoma with a unique intracranial metastatic component in a pediatric patient. A 14-year-old girl with a history of mood disorders presented to the emergency department with a 3-week history of neck torticollis, cervical pain, paresis, and paresthesia of the upper and lower extremities on the left side. Initially, non-organic causes such as somatization or conversion disorder were suspected. She returned 3 months later when her symptoms worsened. MRI of the head and spine was performed, and demonstrated the presence of a suprasellar, retro-chiasmatic mass lesion. There was also diffuse leptomeningeal enhancement, another well-defined intradural extramedullary lesion the sacral region and several multifocal cauda equina soft tissue nodules. The patient first underwent surgery. The patient was also treated with a combination of chemotherapy (vincristine, doxorubicin and cyclophosphamide alternating with ifosfamide and etoposide (VDC/IE)) and radiation as per the Children's Oncology Group AEWS1221 protocol. Most recent imaging conducted 22 months after the initial mass discovery revealed improvement of the suprasellar mass lesion with residual stable appearance of the prominence and enhancement of the pituitary stalk and tuber cinereum. There was interval improvement of the spinal lesions with no convincing residual. Clinically, at almost three years since initial imaging findings, and 25 months since completing treatment, she is stable from an oncology perspective.

During the early development of tetrapods, including humans, the embryonic body elongates caudally once the anterior-posterior axis is established. During this process, region-specific vertebral morphogenesis occurs, with the determination of limb positioning along the anterior-posterior axis. We previously reported that functions as an anatomical integration system that determines the positioning of hindlimbs and sacral vertebrae where is expressed. However, the molecular mechanisms underlying induction of expression remain unclear. In this study, we searched for non-coding regions near the locus that were conserved across species to elucidate the regulatory mechanisms of expression. We identified an enhancer of the gene in intron 1 and named it highly conserved region (HCR). In HCR knockout mice, the expression level of endogenous was decreased, and the position of the sacral-hindlimb unit was shifted posteriorly. We also searched for factors upstream of based on the predicted transcription factor binding sites within the HCR. We found that inhibition of FGF signaling increased endogenous expression, suggesting that FGF signaling negatively regulates expression. However, FGF signaling does not regulate HCR activity. Our results suggest that there are species-specific enhancers other than HCR and that FGF signaling regulates expression independent of HCR.
