There have been limited studies regarding stereotactic and functional neurosurgery for lingual dystonia. Here, we report a patient with primary lingual dystonia who showed significant improvement after bilateral deep brain stimulation (DBS). A 42-year-old woman presented with a 5- to 6-year history of tongue protrusion; however, she lacked a significant medical or medication history before onset. She presented with gradually worsening symptoms and was diagnosed with idiopathic lingual dystonia. Her tongue was injected with botulinum toxin on 6 occasions; however, it had a limited effect. Oral medications were ineffective. She underwent DBS since her involuntary tongue movements were causing nocturnal breathing problems. Directional leads were bilaterally inserted into the internal segment of the globus pallidus (GPi). The directional part of each lead was inserted at the GPi bottom on both sides. The posteromedial contacts were used to deliver stimulation. After 1.5 years, the patient's Burke-Fahn-Marsden dystonia rating scale score improved from 9 to 1.5 and 2 to 1 for movement and disability, respectively. This case demonstrated the effectiveness of bilateral GPi-DBS. Placing the directional part of the lead in the GPi bottom could improve the stimulation effects.

Donors' health and safety are mandatory in the living-donor kidney transplantation procedure. Laparoscopic live donor nephrectomy (LLDN) provides an increase in donor numbers with its benefits and becomes a standard of care. We aimed to explain the results, complication rates, tips, and tricks of the largest number of LLDN case series ever performed in the literature.

Between August 2012 and December 2019, 2,477 live donor case files were analyzed retrospectively. Age, gender, hospitalization times, body mass index, warm ischemia times, operation times, numbers of arteries, side of the kidneys, and complications were noted.

1,421 (57.4%) of 2,477 donors were female (p = 0.007). Operation times and warm ischemia times were found longer in right-sided LLDN and donors with multiple renal arteries (p = 0.046, <0.001, and <0.001, respectively). Obesity (BMI >30 kg/m2) did not affect warm ischemia times while prolonging the operation times (p = 0.013). Hospitalization times and numbers of complications were higher in obese donors.

LLDN seems to be a reliable solution with fewer complications and higher satisfaction rates. We hope to illuminate the way with tips and trick points for beginner transplant surgeons based on the experience obtained from 2,477 LLDN cases.

Nasal inverted papilloma (NIP) is a benign tumour with multiple inflammatory cell infiltration. Tertiary lymphoid organs (TLOs) support local antibody production and play important roles in airway inflammation. However, the evidence of TLOs and local immunoglobulins in NIP has not been reported yet. We investigated the presence of TLOs and immunoglobulins in NIP tissues and their association with the clinical-pathological characteristics of NIPs.

We analyzed the occurrence and composition of TLOs and local immunoglobulins by immunohistochemistry and evaluated the lymph organogenesis associated genes and cytokines by quantitative qPCR and Luminex assays, respectively, in papilloma tissues from 84 NIP cases.

TLOs were present in 54% (45/84) of the NIP patients but not in control subjects. TLOs were composed of T cells, B cells, follicular dendritic cells, macrophages, and natural killer cells. Compared to NIP tissues without TLOs, tissues with TLOs showed significantly higher eosinophil infiltration levels (3.5-fold), elevation of lymphorganogenic genes (CXCL12, CXCL13, CCL20, CCL21, CD21L, and lymphotoxin alpha and beta), and increased Th17 (IL-21, IL-22, and GM-CSF) and Th2 (IL-5 and IL-13) cytokine production. Moreover, NIP with TLOs demonstrated a higher number of follicular T helper cells and immunoglobulin-producing plasma cells (CD138+ IgA+, CD138+ IgM+, CD138+ IgE+, and CD138+ IgG+) than those without TLOs, and these antibody-producing cells were positively correlated with the eosinophil number.

The high frequency of TLOs and excess local immunoglobulin production are associated with an eosinophilic and Th2 skew microenvironment in the NIP mucosa, which would contribute to an important immunopathogenic response during NIP pathogenesis.

Transfer RNA (tRNA) is a noncoding RNA that delivers amino acids to ribosomes for protein synthesis. tRNA is also involved in cell stress response programs. Oxidative stress induces direct conformational change in tRNA structure that promotes subsequent tRNA fragmentation. Using an antibody against tRNA-specific modified nucleoside 1-methyladenosine (m1A), we can detect tRNA derivatives such as conformationally changed tRNA, tRNA-derived fragments, and mononucleotide-free m1A. Based on these findings, tRNA derivatives may have potential as an early tissue damage marker. The purpose of this study was to investigate the plasma tRNA derivatives in stroke patients to clarify whether tRNA derivatives in the acute phase can detect early brain damage and then predict the functional outcome.

Patients (75 patients with ischemic and 66 with hemorrhagic stroke) and 22 healthy volunteers were prospectively enrolled for this study between November 2016 and February 2019. Plasma samples were collected within 24 h and ah ischemic stroke.

The intersection of Bejjani's line with the well-delineated medial subthalamic nucleus (STN) border on MRI has recently been proposed as an individualized reference in subthalamic deep brain stimulation (DBS) surgery for Parkinson's disease (PD). We, therefore, aimed to investigate the applicability across centers of the medial STN border as a patient-specific reference point in STN DBS for PD and explore anatomical variability between left and right mesencephalic area within patients. Furthermore, we aim to evaluate a recently defined theoretic stimulation "hotspot" in a different center.

Preoperative 3-Tesla T2 and susceptibility-weighted images (SWI) were used to identify the intersection of Bejjani's line with the medial STN border in left and right mesencephalic area. Acetalax supplier The average stereotactic coordinates of the center of stimulation relative to the medial STN border were compared with the predefined theoretic stimulation "hotspot."

Fifty-four patients provided 108 stereotactic coordinates of medial STN borders on both sequences.
