Nodo-paranodopathy: Beyond the demyelinating and axonal classification in anti-ganglioside antibody-mediated neuropathies

In some anti-ganglioside antibody-mediated neuropathies, human and experimental data suggest a common pathogenic mechanism of dysfunction/disruption at the node of Ranvier resulting in a pathophysiologic continuum from transitory nerve conduction failure to axonal degeneration. The traditional classification of polyneuropathies into demyelinating or axonal may generate some confusion in the electrophysiological diagnosis of Guillain–Barré syndrome subtypes associated with anti-ganglioside antibodies. The axonal forms show, besides axonal degeneration, promptly reversible nerve conduction failure. This may be interpreted, by a single electrophysiological study, as demyelinating conduction block or distal axonal degeneration leading to errors in classification and in establishing prognosis. Moreover the term axonal may be misleading as it is commonly associated to axonal degeneration and not to a transitory, promptly reversible, dysfunction of the excitable axolemma. To focus on the site of nerve injury and overcome the classification difficulties, we propose the new category of nodo-paranodopathy which seems appropriate to various acute and chronic neuropathies associated with anti-ganglioside antibodies and we think better systematizes the neuropathies characterized by an autoimmune attack targeting the nodal region.     

Pharyngeal Electrical Stimulation for Dysphagia Associated with Multiple Sclerosis: A Pilot Study

ObjectiveTreatment options for dysphagia associated with multiple sclerosis (MS) are currently limited. In this study we investigated whether intraluminal electrical pharyngeal stimulation facilitates swallowing recovery in dysphagic MS patients.Patients and methodsTwenty dysphagic MS patients were randomized to receive 5 Hz “real” pharyngeal stimulation (10 patients) for 10 min or “sham” pharyngeal stimulation for 10 min (10 patients). Patients were evaluated by videofluoroscopic, and electromyographic examinations, and by the Penetration/Aspiration Scale (PAS) performed before (T₀) and immediately after the last session of 5 consecutive days of electrical pharyngeal stimulation (T₁), and then after two (T₂), and four (T₃) weeks of 5 consecutive days of pharyngeal electrical stimulation.ResultsPatients who received “real” stimulation showed a significant improvement in all the swallowing outcome measures as compared with those receiving “sham” stimulation.ConclusionsNo specific treatment for oro-pharyngeal dysphagia related to MS has been described to date. Our preliminary findings suggest a potential benefit of intraluminal electrical pharyngeal stimulation for the treatment of dysphagia caused by MS.     

Toxicity and cosmesis following partial breast irradiation consisting of 40 Gy in 10 daily fractions

PurposeTo assess the toxicity and cosmetic results in breast cancer patients undergoing adjuvant partial breast irradiation (PBI) to a total dose of 40 Gy in 10 daily fractions (4 Gy/fraction).Methods and materialsPatients affected by early-stage breast cancer were enrolled in this phase II trial. Patients had to be 60 years old and treated with breast conservative surgery for early stage (pT1–T2 pN0–N1a) invasive ductal carcinoma.Results77 patients were enrolled. Median follow-up was 18 months. The proposed schedule was well tolerated. One patient reported Grade 3 pain at the site of irradiation. Four (5%) patients experience Grade 2 erythema. Late Grade 2 and 1 fibrosis was observed in 3 (4%) and 14 (18%) patients, respectively. Cosmesis was judged “good/excellent” and “poor” in 75 (97%) and in 2 (3%) patients, respectively.Conclusions40 Gy in 10 daily fractions, 4 Gy/fraction, is a well tolerated regimen to deliver PBI.     

Long-term follow-up of ruptured intracranial aneurysms treated by microsurgical wrapping with autologous muscle

The purpose of this study is to describe our series of nine unclippable and uncoilable ruptured aneurysms in eight patients treated by microsurgical wrapping with autologous muscle. Records were retrospectively reviewed for rebleeding rate, morbidity and mortality, changes in size or the aneurysm’s configurations, and inflammatory reaction. We conducted a Medline search in the post-microsurgical era, excluding patients in whom wrapping was part of the aneurysm treatment in combination with clipping or coiling. The surgically related morbidity was 12.5 %. Global mortality rate was 25 % due to vasospasm (one case) and rebleeding (one case). Six patients are still alive. Rebleeding rate was 14.3 % within 6 months; then, it was zero. Glasgow outcome scale (GOS) score at discharge was 1 and 4 in one patient, respectively, and 5 in the remaining six. Mean clinical follow-up was 126 months. GOS at last follow-up was 4 and 5 in 50 % of patients, respectively. Mean mRS score was 0.8 at 2 months, and 2.4 at 12 months. Follow-up MR demonstrated persistence of the aneurysm’s sac, without changes in size and configuration. Patients did not describe or exhibit symptoms attributable to complications inherent to the use of muscle. Microsurgical muscle-wrapping of ruptured intracranial aneurysm is safe, is associated with a low rate of acute and delayed postoperative complications and rebleeding, and could be a valid alternative for unclippable and non-amenable to endovascular procedure ruptured aneurysms.     

Intestinal Bowel Lengthening in Children with Short Bowel Syndrome: Systematic Review of the Bianchi and STEP Procedures

Background:

It has been thirty years since Bianchi introduced the technique that made intestinal lengthening possible. The last three decades have seen lengthening procedures established as vital components of intestinal rehabilitation programs. The goal of the present study was to use a systematic literature review to determine patient outcomes for the two most commonly used lengthening procedures, the Bianchi procedure and the serial transverse enteroplasty procedure (STEP).

Methods:

Pubmed and Embase were searched using the terms “intestinal lengthening” and “bowel lengthening.” Patient outcomes were extracted from each relevant journal article on the basis of a set proforma. The results were combined to create overall mean outcomes. Mean outcomes were also calculated separately for the Bianchi procedure and STEP. Significance was tested with the independent t-test.

Results:

Overall survival for the last thirty years is 83 %. However, survival for the last fifteen years has been 89 %, with no significant difference between the two procedures. The Bianchi procedure has a higher rate of weaning patients who were static on parenteral nutrition with conservative measures: 55 % versus 48 %. In addition, the Bianchi procedure was associated with a higher rate of patients receiving transplants: 10 % versus 6 %. The STEP has a higher rate of complication. Length of follow-up is significantly longer for the Bianchi procedure: 76 versus 22 months. The impact that this differential could have had on our results must be considered.

Conclusions:

Outcomes for intestinal lengthening procedures are very good, and increasingly so. However, further analysis is required in order to fully understand the relative strengths and weaknesses of each procedure.     

Short-Term Outcomes of Laparoscopy Combined with Enhanced Recovery Pathway after Ileocecal Resection for Crohn’s Disease: a Case-Matched Analysis

Background

Laparoscopy combined with an enhanced recovery pathway (ERP) is widely considered to be the first-choice option for patients with colorectal cancer. However, no previous reports have focused on patients with Crohn’s disease (CD) treated by laparoscopy and ERP.

Methods

Twenty patients with CD underwent laparoscopic ileocecal resection with an ERP at two institutions. The ERP protocol included no bowel preparation nor fasting, no nasogastric tube, no abdominal drains, early removal of urinary catheter, early solid dietary intake and mobilization, opioid-sparing analgesia and restrictive fluid management. This group was compared with a matched historical control group of 70 CD patients who underwent laparoscopic ileocecal resection treated with conventional care.

Results

Compliance with the ERP was high (≥80 %) for all items except no drain placement. A significantly earlier return of bowel function (time to first flatus and stool) was observed in the ERP group. Mean postoperative and total length of stay were significantly shorter in the ERP group. Postoperative complications were similar in both groups.

Conclusions

This is the first reported experience of laparoscopy with ERP in CD patients and suggests that optimized perioperative care combined with minimally invasive techniques may lead to further improvements in surgical outcomes for CD patients.     

Iatrogenic collapse of the nasal valve after aesthetic rhinoplasty

We present our experience of reconstruction of the nasal valve after iatrogenic collapse, and evaluate the feasibility and outcome of composite grafts. We selected all collapsed nasal valves that occurred after primary aesthetic rhinoplasties of the total number done at the University Tor Vergata in Rome. We excluded collapses that followed septoplasty for nasal deviation, reconstructions, and rhinoplasties for trauma. We selected 15 patients of 1252 who presented from January 1998 to December 2003. Eleven patients who had collapse of both the external and internal valve were treated with a composite graft (septum plus retroauricular) inserted by an “open tip” technique. Four patients (1 with both internal and external valve collapse, 3 with only internal) were treated with a section and opening of the upper lateral cartilages, transposition and repositioning of mucocartilaginous flaps. Good functional and aesthetic results were achieved in almost all patients without complications. Composite cartilaginous grafts are an easy and safe technique for the treatment of iatrogenic collapse of the nasal valve.     

Investigating the personality disorder psychotherapy process: The roles of symptoms,quality of affects,emotional dysregulation,interpersonal processes,and mentalizing

Abstract

Personality Disorders (PDs) can reasonably hope to gain benefit from psychotherapy. Nevertheless many patients do not fully respond. Research therefore has to be done into which variables need to be targeted in psychotherapy, in order to tailor treatment to the needs of the majority of PD patients. These have to date been understudied, in particular where patients have PD other than borderline and where they obtain no or limited benefits from available treatments. Many elements of the therapy process, such as therapy alliance, can be investigated. We outline here some personality pathology core issues and then describe how the authors involved in this special issue investigated the roles of symptoms, emotional experience and regulation, interpersonal patterns and mentalizing in PD psychotherapy.
