Abstract. Background: The technical and clinical outcomes of catheter-directed embolization for peripheral arteriovenous malformations (AVM) using Onyx® (ethylene-vinyl alcohol copolymer) are not well documented. The purpose of this study was to retrospectively assess the safety, technical outcomes and clinical outcomes of catheter-directed Onyx® embolisation for the treatment of symptomatic peripheral AVMs. Patients and methods: Demographics, (pre-)interventional clinical and radiological data were assessed. Follow-up was based on hospital medical records and telephone calls to the patients’ general practitioners. Radiological success was defined as complete angiographic eradication of the peripheral AVM nidus. Clinical success was defined as major clinical improvement or complete disappearance of the initial symptoms. Results: 25 procedures were performed in 22 patients. The principal indications for treatment were pain (n = 10), limb swelling (n = 6), recurrent bleeding (n = 2), tinnitus (n = 3), and exertional dyspnoea (n = 1). Complete radiological success was obtained in eight patients (36 %); near-complete eradication of the nidus was achieved in the remaining 14 patients. Adjunctive embolic agents were used in nine patients (41 %). Clinical success was observed in 18 patients (82%). Major complications were reported in two patients (9 %). During follow-up, seven patients (32 %) presented with symptom recurrence, which required additional therapy in three patients. Conclusions: Catheter-directed embolisation of peripheral AVMs with Onyx® resulted in major clinical improvement or complete disappearance of symptoms in the vast majority of patients, although complete angiographic exclusion of the AVMs occurred in only a minority of patients.

Among the activities appointed by the EC research-project “Integrated water recycling and emission abatement in the textile industry” (Contract: ENV4-CT95-0064), the effectiveness of ozone for improving the biotreatability of recalcitrant effluents as well as for removing from them toxic and/or inhibitory pollutants has been evaluated at lab-scale. Real membrane concentrates (pH=7.9; TOC=190 ppm; CDO=595 ppm; BOD5=0 ppm; Conductivity=5,000 μS/cm; Microtox-EC20=34%) produced at Bulgarograsso (Italy) Wastewater Treatment Plant by nanofiltering biologically treated secondary textile effluents, have been treated with ozonated air (O3conc.=12 ppm) over 120 min. The results have indicated that during ozonation, BOD5 increases from 0 to 75 ppm, whereas COD and TOC both decrease by about 50% and 30 % respectively. As for potentially toxic and/or inhibitory pollutants such as dyes, nonionic surfactants and halogenated organics, all measured as sum parameters, removals higher than 90% were achieved as confirmed by the complete disappearance of acute toxicity in the treated streams. The only ozonation byproducts searched for and found were aldehydes whose total amount continuously increased in the first hour from 1.2 up to 11.8 ppm. Among them, formaldehyde, acetaldehyde, glyoxal, propionaldehyde, and butyraldehyde were identified by HPLC.

AbstractA study of apatite crystals from the Asio mine, Japan, showed sectoral texture related to the growth of the crystal, and with optically biaxial properties within the sectors. Wet chemical analysis gave a composition Ca5(PO4)3(F0.64,OH0.38,Cl0.01)1.03 for the specimen.Additional diffraction spots were not observed in precession and oscillation X-ray photographs and electron diffraction photographs. Since the internal textures correlate with the surface growth features, it is suggested that the internal textures and the unusual optical properties were produced during nonequilibrium crystal growth. The fluorine/hydroxyl sites in hexagonal apatite are symmetrically equivalent in the solid crystal but, at a growth surface, this equivalence may be lost, resulting in a reduction of crystal symmetry. Heating of the apatite to about 850°C results in the almost complete disappearance of the optical anomalies due to disordering, which may be related to the loss of hydroxyl from the crystal.

Abstract Background Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disease associated with neurological complications, including cerebral abscesses (CA). They tend to be unique, supratentorial and lobar. While the surgical intervention is a rule of thumb when treating and diagnosing the etiology of these lesions, this is not always possible due to dangerous or inaccessible locations. We report the case of a patient solely treated with empiric antibiotics without stereotaxic intervention and satisfactory results. Case presentation We present the case of a 21-year-old patient with a right thalamic abscess due to HHT and pulmonary arteriovenous malformations, previously embolized, treated solely with antibiotics. At first, we contemplated the possibility of a stereotaxic biopsy, but the high-risk location and the fact that our patient received a previous full course of antibiotic treatment (in another center), made us discard this intervention because of the low diagnostic yield. We started an empiric antibiotic regime. We followed up very closely the clinical and radiological evaluation the next weeks, adjusting our antibiotic treatment when necessary. The results were favorable from both the radiological and clinical aspects and 6 months after the diagnosis the images show its almost complete disappearance. Conclusion Carefully tailored antibiotic-only regime and vigilance of its adverse effects and close radiological following is a good treatment approach when surgery is not an option.

Here, we report on a rare case of gastric hyperplastic polyps which disappeared after the discontinuation of proton pump inhibitor (PPI). The patient was an 83-year-old woman with liver cirrhosis and portal hypertension, along with gastroesophageal reflux disease treated by PPI. An initial upper gastrointestinal endoscopy showed unique polypoid lesions in the greater curvature of the stomach. Biopsy specimens of the lesions were diagnosed as hyperplastic polyps and she was followed. One year later, a second endoscopy showed that the lesions had increased in number and size, and an endoscopic mucosal resection (EMR) was performed for the main polyps. The resected specimens indicated a proliferation of foveolar epithelium cells with an increase of capillary ectasia and parietal cell hyperplasia, which was thought to be induced by hypergastrinemia from the PPI. Three months after the EMR, she was admitted because of bleeding from the remaining polyps along with an increase in new polyps. After conservative treatment, PPI was stopped and rebamipide was used. One year and 6 months later, an endoscopy showed the complete disappearance of all gastric polyps.

Liposarcoma (LPS) is the most common soft tissue sarcoma. Myxoid LPS (MLPS) is the second most common subtype of LPS and accounts for 25% to 50% of all LPSs. Like most other soft tissue sarcomas, the mainstay of treatment for LPS is inevitably surgery. Multidisciplinary approaches, including surgery, chemotherapy, and radiotherapy, have been successful in the treatment of LPS during the last three decades. Even so, recurrence of LPS remains challenging. Carbon ion beams produce increased energy deposition at the end of their range to form a Bragg peak while minimizing irradiation damage to surrounding tissues, which facilitates more precise dosage and localization than that achieved with photon beams. Furthermore, carbon ion beams have high relative biologic effectiveness. We herein describe a patient who developed recurrent MLPS in the right calf after two surgeries and underwent carbon ion radiotherapy (CIRT), achieving complete disappearance of the tumor. The patient developed Grade 1 radiation dermatitis 30 days after CIRT, but no other acute toxicities were observed. The tumor had completely disappeared by 120 days after CIRT, and the patient remained disease-free for 27 months after CIRT. The CARE guidelines were followed in the reporting of this case.

Abstract More than three-quarters of victims of brachial plexus injury suffer from refractory neuropathic pain.1-6 Main putative mechanism is paroxysmal hyperactivity in the dorsal horn neurons at the dorsal root entry zone (DREZ) as demonstrated by microelectrode recordings in animal models7 and patients.8 Pain relief can be achieved by lesioning the responsible neurons in the spinal cord segments with avulsed rootlets.9,10  This video illustrates the technique for microsurgical DREZotomy.11,12 A C3-C7 hemilaminectomy is performed to access the C4-Th1 medullary segments. After opening the dura and arachnoid, and freeing the cord from arachnoid adhesions, the dorsolateral sulcus is identified. Identification can be difficult when the spinal cord is distorted and/or has a loss of substance. The dorsolateral sulcus is then opened with a microknife, so that microcoagulations are performed: 4 mm deep, at 35° angle in the axis of the dorsal horn, every millimeter in a dotted fashion along the avulsed segments. Care should be taken not to damage the corticospinal tract, laterally, and the dorsal column, medially.  The patient consents to the procedure. In the presented case, surgery led to complete disappearance of the paroxysmal pain and reduced the background of burning pain to a bearable level without the need of opioid medication. There was no motor deficit or ataxia in the ipsilateral lower limb postoperatively. According to Kaplan-Meier analysis at 10 yr follow-up, in our overall series, microsurgical DREZotomy achieved total pain relief without any medication in 60% of patients, and in 85% without the need for opioids.10,13-15  Microelectrode recording at 1:26 reproduced from Guenot et al7 with permission from JNSPG.

In this work, polymeric membranes functionalized with ionic liquids (ILs) and exfoliated graphene nanoplatelets (xGnP) were developed and characterized. These membranes based on graphene ionanofluids (IoNFs) are promising materials for gas separation. The stability of the selected IoNFs in the polymer membranes was determined by thermogravimetric analysis (TGA). The morphology of membranes was characterized using scanning electron microscope (SEM) and interferometric optical profilometry (WLOP). SEM results evidence that upon the small addition of xGnP into the IL-dominated environment, the interaction between IL and xGnP facilitates the migration of xGnP to the surface, while suppressing the interaction between IL and Pebax®1657. Fourier transform infrared spectroscopy (FTIR) was also used to determine the polymer–IoNF interactions and the distribution of the IL in the polymer matrix. Finally, the thermodynamic properties and phase transitions (polymer–IoNF) of these functionalized membranes were studied using differential scanning calorimetry (DSC). This analysis showed a gradual decrease in the melting point of the polyamide (PA6) blocks with a decrease in the corresponding melting enthalpy and a complete disappearance of the crystallinity of the polyether (PEO) phase with increasing IL content. This evidences the high compatibility and good mixing of the polymer and the IoNF.

Abstract Pyogenic granuloma also known as lobular capillary hemangioma occurs commonly in the skin and oral mucosa. This entity has been rarely reported in the gastrointestinal tract. We herein report three cases of pyogenic granuloma, located in the duodenum, ileum, and rectum, respectively. Case 1 is a 54-year-old female with a history of angioimmunoblastic T-cell lymphoma who underwent an esophagogastroduodenoscopy for severe heartburn. The endoscopy showed a 13-mm nonbleeding, pedunculated polyp in the second portion of duodenum, which was removed using a hot snare after injection of epinephrine. The patient had an episode of massive gastrointestinal bleeding postpolypectomy, with a significant drop of her hemoglobin, which was managed with blood transfusion. Case 2 is a 68-year-old male with a history of right hemicolectomy due to trauma who had a colonoscopy for chronic diarrhea. The colonoscopy revealed a 14-mm, nonbleeding, pedunculated polyp in the ileum, located 3 cm from the ileocolonic anastomosis. The polyp was removed with hot snare, without complications. Case 3 is a 44-year-old female with morbid obesity who underwent a colonoscopy for iron-deficiency anemia. The colonoscopy showed an 8-mm multilobulated sessile lesion in the distal rectum, which was completely removed using hot snare. No complications were seen postpolypectomy. Histological examination of all the three polyps showed a proliferation of capillary-sized blood vessels with a mixed inflammatory infiltrate, resembling granulation tissue. Additionally, the ileal polyp in our case had marked eosinophilic infiltrate, the etiology of which remains unknown. In conclusion, pyogenic granuloma, given its vascular nature, can be a cause of bleeding in the gastrointestinal tract. Awareness regarding this rare entity is important for its proper diagnosis and treatment.

Hemiplegic Migraine

AbstractFamilial hemiplegic migraine type 2 (FHM2) is an autosomal dominant inheritance disorder caused by ATP1A2 mutation, and the clinical spectrum is heterogeneous even with acute severe encephalopathy. However, up to now, early treatments against acute and severe attacks in FHM2 are still insufficient. Here, we report a 15-year-old female with intellectual disability due to FHM2 caused by a pathogenic ATP1A2 gene mutation, presenting mild-to-moderate headache at the onset, followed by confusion, complete right hemiparalysis, epileptic partial seizures, and conscious disturbance with rapid progression in acute attack. Brain magnetic resonance imaging (MRI) and magnetic resonance spectroscopy have revealed left extensive cerebral cortex edema, slightly decreased N-acetylaspartate for neuronal damage, and mildly increased lactate acid for mitochondrial dysfunction throughout the hemispheric swollen cortex. The patient is diagnosed as severe encephalopathy caused by FHM2. Based on literature review about pathophysiologic mechanism described in FHM2 recently, we use early treatments including prevention of glutamatergic excitotoxicity and protection of mitochondria function, as well as traditional antimigraine drug. The symptoms are all greatly improved and recovered within a short time, and follow-up MRI also shows complete disappearance of edema throughout the left hemispheric cortex. Altogether, the approach in our case may reduce the severity and duration of encephalopathy effectively, expend therapeutic options, and provide helpful references for acute severe encephalopathy in FHM2.
