Abstract Purpose Cervical pedicle screw (CPS) instrumentation offers significant biomechanical advantages compared to lateral mass or transarticular fixation. Nonetheless, malpositioning complications constitute a relevant concern. Customized patient-specific 3D-printed templates have been developed improve CPS placement accuracy and safety. The aim of this study is present our experience with surgical technique its safety in clinical setting. Methods This single-center retrospective...

Abstract Post‐infectious bronchiolitis obliterans (PBO) is a rare form of chronic obstructive lung disease in children with few data on the pulmonary function outcome and underlying inflammatory process. The aim this study was to determine change over time investigate by bronchoalveolar lavage (BAL) characteristics involvement. Eleven Caucasian PBO were evaluated estimate average rate indices using mixed model. differential cytology lymphocyte subsets BAL fluid analyzed. median follow‐up...

The role of hormonal and reproductive factors as risks for cutaneous malignant melanoma (CMM) was explored by means a population-based case-control study conducted in Turin, north-western Italy, on 186 female CMM cases 205 controls. Past use oral contraceptives (OC) did not seem to exert any effect risk odds ratio (OR) = 1.12, 95% confidence interval (CI): 0.56-2.24). No association found even the longest duration use, superficial spreading lower limbs only. While age at first birth affect...

Introduction: The main clinical manifestation of the novel Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is respiratory issues. Neurological manifestations are being increasingly recognized, including febrile seizures, headache, dizziness, and myalgia, as well encephalopathy, encephalitis, stroke, acute peripheral nerve diseases. Cerebral vasculitis rarely reported. We describe a case SARS-CoV-2 interstitial pneumonia complicated by flaccid tetraplegia due to Guillain-Barré...

Skin involvement is common in sinus histiocytosis with massive lymphadenopathy (SH, Rosai-Dorfman disease), but pure cutaneous cases are rare. A 70-year-old woman presented a 10-year history of large red-orange nodules and plaques on her upper arms, face, buttocks, without evidence or internal involvement. Distinctive histopathologic differences were observed according to the duration lesions. In recent lesions, dermal infiltrate was mostly composed sheets characteristic SH cells; other...

Cyclohexanone monooxygenase from Acinetobacter calcoaceticus catalyzes the asymmetric oxidation of tert-butyl disulfide to enantiomerically pure (R)-tert-butyl tert-butanethiosulfinate. Lower enantioselectivities and conversions were observed in i-propyl, n-butyl, p-tolyl disulfides alkylthiophosphonates. Chirality 13:40–42, 2001. © 2000 Wiley-Liss, Inc.

<title>Abstract</title> Hydrocephalus is a common pathology in the neurosurgical field. Since first permanent ventriculo-subarachnoid-subgaleal shunt by Mikulicz 1893, there were multiple attempts to find solution drain excess production/less reabsorption of cerebrospinal fluid (CSF) from brain. Nowadays most used technique Ventriculo-Peritoneal Shunt (VPS), whereas ventriculo-atrial (VAS) only some rare conditions. To date are still no specific guidelines or strong evidences literature...
