To identify the location of the Riché-Cannieu anastomosis (RCA) in relation to the Cardinal Kaplan Line (KCL) and the Y line. A total of 20 hands of 10 recently-deceased adult male cadavers aged between 27 and 66 years were dissected for the investigation of the relationship of the most distal point of the RCA with the KCL and with the Y line, drawn from the axis of the third metacarpal head, following the longitudinal axis of the hand. In 20 limbs, the most distal point of the nerve communication was positioned distally in relation to the KCL. The Y line was positioned on the radial side in relation to the most distal point of the RCA in 14 limbs, and it was positioned on the ulnar side in relation to the Y line in 6 limbs. The crossing between the KCL and the Y line occurred proximal to the RCA in 18 limbs; in 1 hand, it was positioned distal to the intersection between these lines; and in another hand, the KCL was positioned exactly on the RCA. Knowledge of these anatomical relationships can prevent damage to nerve branches and thus also prevent paralysis of intrinsic muscles in surgical procedures in the palm of the hand.

Bilateral facial palsy with paresthesia (FDP) is a rare variant of GBS, characterized by simultaneous bilateral facial palsy and paresthesia of the distal limbs. Mounting evidence indicates that the presence of anti-GT1a IgG has a pathogenic role as an effector molecule in the development of cranial nerve palsies in certain patients with GBS, whereas anti-GT1a antibody is rarely presented positive in FDP. Here, we report the case of a 33-year-old male diagnosed with FDP presented with acute onset of bilateral facial palsy and slight paresthesias at the feet as the only neurological manifestation. An antecedent infection with no identifiable reason for the fever or skin eruptions was noted in the patient. He also exhibited cerebrospinal fluid albuminocytologic dissociation and abnormal nerve conduction studies. Notably, the testing of specific serum anti-gangliosides showed positive anti-GT1a IgG/IgM Ab. The patient responded well to intravenous immunoglobulin therapy. This case brings awareness to a rare variant of GBS, and provides the first indication that anti-GT1a antibodies play a causative role in the development of FDP. The case also suggests that prompt management with IVIG should be implemented if FDP is diagnosed.

Journal of Neuroendovascular Therapy 2024To report the rare case of a patient with a perianeurysmal cyst following stent-assisted coil embolization of an unruptured vertebral artery aneurysm.
OBJECTIVE
To report the rare case of a patient with a perianeurysmal cyst following stent-assisted coil embolization of an unruptured vertebral artery aneurysm.
CASE PRESENTATION
A 63-year-old woman underwent stent-assisted coil embolization for an unruptured vertebral artery aneurysm embedded in the brainstem (pons). Complete occlusion of the aneurysm was successfully achieved. However, subsequent magnetic resonance imaging (MRI) conducted 8 months after the procedure showed perilesional edematous changes surrounding the aneurysm, and at 20 months, cyst formation was observed in the vicinity of the aneurysm. Progressive enlargement of the cyst eventually led to the development of paralysis and dysphagia, necessitating cyst fenestration surgery. Although postoperative reduction in the cyst size was achieved, the patient experienced complications in the form of aspiration pneumonia and bacterial meningitis, which resulted in a life-threatening condition.
CONCLUSION
Aneurysms embedded in the brain parenchyma should be carefully followed up, recognizing the risk of perianeurysmal cyst formation after coil embolization.

KEY CLINICAL MESSAGE
Melkersson-Rosenthal syndrome can cause recurring bilateral facial paralysis. When steroids fail, surgical decompression of facial nerve is recommended, with endoscopic trans-canal decompression as a safe, minimally invasive, and effective option.
ABSTRACT
Melkersson-Rosenthal syndrome (MRS) is a rare neuro-mucocutaneous disorder, clinically diagnosed by a triad of orofacial swelling, recurrent facial palsy, and fissured tongue. Due to the lack of a comprehensive understanding of MRS, there is no accepted standard of care. In this study we report a 30-year-old female patient, who was referred to the otolaryngology clinic of Rasool Akram Hospital, with classical triad of MRS that was managed by endoscopic trans-canal facial nerve decompression. Bilateral endoscopic trans-canal facial nerve decompression was done when we did not find any improvement with systemic steroids. Endoscopic trans-canal facial nerve decompression could be a safe, reliable minimal invasive treatment of facial paralysis in MRS patients. It needs no external incision or temporal bone drilling which makes this method more convenient for patients with shorter recovery time.

BMC Veterinary Research Jun 2024This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
BACKGROUND
This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
CASE PRESENTATION
A 13-year-old, neutered male dog, weighing 14 kg, mixed-breed, presented with apathy, anorexia, acute-onset vomiting, and abdominal discomfort during the physical examination. Ultrasonography and pyelography revealed a right-sided dilation of the renal pelvis and ureter due to complete obstruction in the middle third of the ureter. A mass obstructing the lumen of the right ureter was completely resected, and ureteral suturing was performed, preserving the integrity of the involved structures. Histopathology confirmed primary ureteral hemangiosarcoma. Due to the local and non-invasive nature of the mass, chemotherapy was not initiated. The patient's survival was approximately two years, and normal renal function was preserved throughout this period.
CONCLUSIONS
Considering this type of tumor in the differential diagnosis of upper urinary tract obstructive disorders. Furthermore, the preservation of the ureter and kidney is a suitable therapeutic option after surgical resection of non-invasive tumors.

This research presents a dataset consisting of electroencephalogram and eye tracking recordings obtained from six patients with amyotrophic lateral sclerosis (ALS) in a locked-in state and one hundred seventy healthy individuals. The ALS patients exhibited varying degrees of disease progression, ranging from partial mobility and weakened speech to complete paralysis and loss of speech. Despite these physical impairments, the ALS patients retained good eye function, which allowed them to use a virtual keyboard for communication. Data from ALS patients was recorded multiple times at their homes, while data from healthy individuals was recorded once in a laboratory setting. For each data recording, the experimental design involved nine recording sessions per participant, each corresponding to a common human action or demand. This dataset can serve as a valuable benchmark for several applications, such as improving spelling systems with brain-computer interfaces, investigating motor imagination, exploring motor cortex function, monitoring motor impairment progress in patients undergoing rehabilitation, and studying the effects of ALS on cognitive and motor processes.

BACKGROUND
This manuscript aims to describe the symptoms, demographics, surgical approaches and techniques, the volume of surgical interventions, histological results, intra- and postoperative complications, and postoperative results in patients with anterior mediastinal tumors of thyroid origin (AMTTO).
METHODS
Twenty patients with AMTTO were operated between 2017 and 2021. Fifteen were women and 5 were men. The mean age was 66.8 years.
RESULTS
The most common histology was nodular micro- and macrofollicular goiter (15/20, 75%). Kocher cervicotomy (65%) was the preferred approach. Total thyroidectomy was performed in 95% of patients. Intraoperative complications were identified in 25% (5/20), and in 2 patients a tracheostomy was required. Early postoperative complications were established in 65% and the most common was unilateral transient recurrent nerve paresis or paralysis and dysphonia (25%).
CONCLUSIONS
Commonly resection of AMTTO is a challenge due to its complexities associated with high-risk cases, emphasizing the need for experienced centers in managing such cases.

Observational Study
Analysis of factors associated with patients' global impression of change scores in inpatients with peripheral facial palsy: A retrospective study at a Korean Medicine Hospital.
The incidence of peripheral facial palsy is on the rise, with psychological issues influencing quality of life due to visible symptoms. Consequently, patient-reported outcome measures are critical in assessing the disease burden and the treatment efficacy of peripheral facial palsy from patients' perspective. This study examines factors influencing patients' global impression of change (PGIC) scores, a type of patient-reported outcome measure, in hospitalized patients with peripheral facial palsy. This retrospective study analyzed the electronic medical records of 200 patients with peripheral facial palsy who were admitted to the Korean Medicine Hospital, Kyung Hee University Medical Center from May 1, 2022 to April 30, 2023. Impact of demographic, electrophysiological, intervention, and clinical factors on PGIC scores were evaluated. Descriptive statistics showed that the length of hospitalization (P = .020), time from disease onset to hospitalization (P = .022), lacrimal disorders (P = .002), House-Brackmann (HB) grade evaluated at admission (P = .016) and at discharge (P < .001), improvement in HB-grade from admission to discharge (P = .002), and total facial disability index (FDI) score at discharge (P < .001) were significantly associated with PGIC scores. In multivariate logistic regression analysis, HB-grade at admission (OR: 13.89, 95% CI: 2.18-113.60), length of stay (OR: 0.27, 95% CI: 0.07-0.92), time from disease onset to hospitalization (OR: 5.55, 95% CI: 1.36-24. 77), tear-related symptoms (OR: 0.41, 95% CI: 0.17-0.96), total FDI score (OR: 0.45, 95% CI: 0.20-0.98), and greater improvement in HB-grade at discharge compared to admission (OR: 0.08, 95% CI: 0.02-0.31) were significantly associated with PGIC scores. Patients with milder initial disease severity, hospitalization period exceeding 7 days, shorter time from disease onset to hospitalization, improvement of lacrimal symptoms, total FDI score, and HB-grade between admission and discharge experienced more significant subjective improvement in peripheral facial palsy.

Observational Study
This study aimed to characterize the risk factors, etiology, clinical manifestations, anatomical characteristics, stroke mechanisms, imaging features, and prognosis of bilateral medial medullary infarction (BMMI). A retrospective analysis was conducted on 11 patients with BMMI who met the inclusion criteria at the Affiliated Hospital of Xuzhou Medical University from January 2013 to January 2023. The patients' imaging and clinical features were analyzed and summarized. Eleven patients (7 male, 4 female), aged 46 to 62 years, met the inclusion criteria. Common clinical presentations included dysarthria (90.9%), dysphagia (90.9%), quadriplegia (81.8%), and so on. Within 72 hours of onset, 8 cases presented with quadriplegia, 2 cases with hemiplegia, and 1 case without limb paralysis. The main risk factor for BMMI was hypertension, followed by diabetes. "Heart appearance" infarcts occurred in 4 cases (36.4%), while "Y appearance" infarcts occurred in 7 cases (63.6%). Among the patients, 3 had unilateral vertebral artery stenosis or occlusion, 5 had bilateral vertebral artery stenosis or occlusion, 2 had normal vertebral basilar artery, and 1 did not undergo cerebrovascular examination. All patients received standardized treatment for cerebral infarction. The prognosis was poor, with 81.8% of patients having an unfavorable outcome, including 1 death, 9 cases of disability, and only 1 patient achieving self-care ability after recovery. BMMI is more prevalent in males aged 45 to 60 years. The main risk factors are hypertension and diabetes. Atherosclerosis is the primary etiological subtype. The main clinical manifestations are dyskinesia, dizziness, quadriplegia, and dysarthria. The prognosis of BMMI is poor. The specific imaging features of "heart appearance" or "Y appearance" infarcts aid in the diagnosis of BMMI.

PURPOSE
Surgical reconstruction of elbow extension can help restore function in patients with tetraplegia and triceps paralysis because of spinal cord injury. Both posterior deltoid-to-triceps tendon transfer and transfer of the branch of the axillary nerve to the triceps motor branch of the radial nerve have been described for triceps reanimation. This systematic review aimed at reviewing current evidence in the two schools of surgery in terms of their outcome and complication profile.
METHODS
A systematic review was conducted using MEDLINE (1974-2023) and EMBASE (1946-2023) databases. The keyword terms "elbow extension," "triceps," "deltoid," "nerve transfer," "spinal cord injury," "tetraplegia," "quadriplegia," and "tetraplegic" were used in the initial search, which was supplemented with manual searches of the bibliographies of retrieved articles.
RESULTS
Twenty studies met our inclusion criteria, with 14 studies (229 limbs) on posterior deltoid-to-triceps tendon transfer, 5 studies (23 limbs) on axillary to radial nerve transfer, and 1 study (1 limb) on combined transfer. For the tendon transfer group, the majority of studies reported a median triceps power of grade 3, with a wide range of failure percentage to reach antigravity (0% to 87.5%). Common complications included gradual stretching of the musculotendinous unit, rupture of the tendon transferred, elbow contracture, and infection. For the nerve transfer group, the majority of studies also reported a median triceps power reaching grade 3. There were no reported complications or loss of power in donor action of shoulder abduction or external rotation.
CONCLUSIONS
Transfer of the axillary nerve branch to the triceps motor branch of the radial nerve in tetraplegia shows promising results, with comparable triceps muscle power compared to traditional tendon transfer and a low incidence of complication.
