Negative symptom severity at discharge from an index hospitalization and subsequent use of psychiatric care resources: A retrospective 1-year follow-up study on 450 patients with schizophrenia spectrum disorders.

Negative symptoms of schizophrenia have a great impact on patients' functioning and are among the most important contributors to subject's disability. However, few studies have assessed the role of type and severity of symptomatology of schizophrenia on the psychiatric care resource utilization. We investigated if the clinical profile of patients at discharge from an index hospitalization might be associated with a different use of psychiatric care resources in the subsequent 1-year period in a large population of patients with schizophrenia spectrum disorders. Clinical records of 450 patients with schizophrenia spectrum disorders admitted in an acute psychiatric inpatient service and subsequently followed in the outpatient services of the same Department were reviewed. Patients with more severe negative symptoms at discharge from hospital showed a higher number and duration of hospitalizations in the 1-year follow-up, as well as a higher number of rehabilitative residential admissions than patients with milder severity of negative symptoms. The same was true for patients with predominant negative symptoms. A global resource utilization index indicated a higher use of psychiatric resources in patients with higher severity of negative symptoms. In conclusion, showing moderate to severe negative symptoms versus positive symptoms at discharge from a hospitalization for an acute exacerbation of schizophrenia spectrum disorder does predict a higher use of psychiatric care resources. This underlines the importance of relieving negative symptoms even in the acute phase of treatment and the need to develop more effective treatments for this symptom dimension.

Local excision in rectal cancer patients with major or complete clinical response after neoadjuvant therapy: a case-matched study.

PURPOSE: To assess the long-term oncological outcomes in patients with locally advanced rectal cancer who underwent neoadjuvant therapy followed by local or total mesorectal excision. METHODS: Patients with locally advanced rectal adenocarcinoma who received neoadjuvant therapy from 2005 to 2017 were evaluated. Those with major or complete clinical response underwent a full-thickness local excision. Kaplan-Meier estimates were used to evaluate overall, disease-free, and local recurrence-free survival of patients who underwent local excision (LE group) and were compared with a matched cohort of patients who underwent total mesorectal excision (TME group). RESULTS: Among 252 patients who received neoadjuvant therapy for rectal cancer, 51 (20.2%) underwent a local excision. At a median follow-up of 61 months, patients who underwent local excision were stoma-free in 88.2% of cases and with rectum preserved in 78.5% of cases, respectively. The estimated 5-year local, disease-free, and overall survival was 91.8% vs 97.6% (95% CI: 79.5-96.8 vs 84.6-99.6), 86.7% vs 86.4% (95% CI: 72.5-93.9 vs 70.1-94.1), and 85% vs 90% (95% CI: 69.0-93.0% vs 75.3-96.2), in the study and matched control group, respectively. None of the differences was statistically significant. CONCLUSIONS: One-fifth of patients with locally advanced rectal cancer are manageable with a rectum-sparing approach after neoadjuvant therapy. With this strategy, about 80% patients will have their rectum preserved and 90% will be without stoma at long term.

Metastatic pattern and new primary tumours after neoadjuvant therapy and surgery in rectal cancer.

AIM: Current follow-up guidelines for distant tumour recurrence after rectal cancer surgery are not defined or agreed. The aim was to elucidate the pattern of recurrence over time and provide information that could help direct a strategy for surveillance. METHOD: In all, 378 patients with locally advanced rectal cancer were treated with preoperative chemoradiotherapy and surgery with curative intent. Patients were followed up with a standard protocol, and data were prospectively collected in a dedicated database. Disease-free survival and overall survival were calculated. RESULTS: Within a median follow-up time of 75 months, rates of local and distant recurrence were 2.6% and 21.7%, respectively. Risk factors for recurrence were a baseline carcinoembryonic antigen > 5.0 ng/ml, a distance from the anal verge ≤ 5 cm, R1 resection margins, G3 grading, ypT staging > 2, positive lymph node status and a tumour regression grade of 3-5. Disease-free survival did not vary significantly between patients with lung and extra-pulmonary metastases (P = 0.59). The only factor associated with increased risk of lung metastases was a distance of the tumour from the anal verge of ≤ 5 cm (P = 0.01). Most recurrences occurred within the first 3 years after surgery (74.4%). The first site of recurrence was most frequently the lung (52.0%). The most frequent new primary malignancy was lung cancer (22.5%). CONCLUSIONS: Patients undergoing curative therapy for rectal cancer often experience distant recurrence; the majority of recurrences occur within the first 3 years after surgery and lung metastases are the most common. A predictive factor for pulmonary recurrence is a tumour in the lower rectum.

Rectal sparing approach after preoperative radio- and/or chemotherapy (RESARCH) in patients with rectal cancer: a multicentre observational study.

BACKGROUND: Rectum-sparing approaches appear to be appropriate in rectal cancer patients with a major (mCR) or complete clinical response (cCR) after neoadjuvant therapy. The aim of the present study is to evaluate the effectiveness of rectum-sparing approaches at 2 years after the completion of neoadjuvant treatment. STUDY DESIGN: Patients with rectal adenocarcinoma eligible to receive neoadjuvant therapy will be prospectively enrolled. Patients will be restaged 7-8 weeks after the completion of neoadjuvant therapy and those with mCR (defined as absence of mass, small mucosal irregularity no more than 2 cm in diameter at endoscopy and no metastatic nodes at MRI) or cCR will be enrolled in the trial. Patients with mCR will undergo local excision, while patients with cCR will either undergo local excision or watch and wait policy. The main end point of the study is to determine the percentage of rectum preservation at 2 years in the enrolled patients. CONCLUSION: This protocol is the first prospective trial that investigates the role of both local excision and watch and wait approaches in patients treated with neoadjuvant therapy for rectal cancer. The trial is registered at clinicaltrials.gov (NCT02710812).

Enhanced torque-based impedance control to assist brain targeting during open-skull neurosurgery: a feasibility study.

BACKGROUND: Cooperatively-controlled robotic assistance could provide increased positional accuracy and stable and safe tissue targeting tasks during open-skull neurosurgical procedures, which are currently performed free-hand. METHODS: Two enhanced torque-based impedance control approaches, i.e. a variable damping criterion and a force-feedback enhancement control, were proposed in combination with an image-based navigation system. Control systems were evaluated on brain-mimicking phantoms by 13 naive users and 8 neurosurgeons (4 novices and 4 experts). RESULTS: In addition to a 60% reduction of user effort, the combination of the proposed strategies showed comparable performances with respect to state-of-the-art admittance controller, thus satisfying the clinical accuracy requirements (below 1 mm), reducing the hand tremor (by a factor of 10) and the tissue's indentation overshooting (by 80%). CONCLUSION: Although the perceived reliability of the system should be improved, the proposed control was suitable to assist targeting procedures, such as brain cortex stimulation, allowing for accurate, stable and safe contact with soft tissues.

Hypovitaminosis D in an hospitalized old population of Western Friuli.

OBJECTIVES: Hypovitaminosis D is very common in the elderly in Italy and generally in the world, contributing to bone fractures and muscle weakness. The aim of the study was to evaluate bone metabolism in an old population of patients hospitalized not for musculo-skeletal complaints. METHODS: The clinical records of 175 patients, 98 female and 77 male, aged >65 years, hospitalized in a Department of Internal Medicine (Sacile, Western Friuli) were retrospectively reviewed. Serum levels of calcium, phosphorous, alkaline phosphatase, parathyroid hormone (PTH) and 25-OH vitamin D were evaluated. Correlations between these parameters were investigate. RESULTS: Abnormalities of bone metabolism parameters were frequently founded, particularly hypocalcemia, increased PTH and reduced 25-OH vitamin D. Hypovitaminosis D were detected in 88% of patients, low levels in 30.28% and very low levels in 57.72%. Hypovitaminosis D was related to female sex, old age of patients and high levels of PTH. CONCLUSIONS: Our data confirm that hypovitaminosis D is very common in elderly population. The study has been performed in an Italian Region where the supplementation of vitamin D in the elderly is not performed, suggesting that a awareness campaign of the doctors could be very useful to prevent bone metabolism abnormalities.

Transverse maxillary stability assisted by a transpalatal device: a retrospective pilot study of 9 cases.

This retrospective pilot study assessed the transverse stability of an original surgical approach in nine patients with moderate transverse maxillary deficiency associated with a sagittal and/or vertical skeletal anomaly. During the one-stage surgical procedure, bi- or three-dimensional anomalies were corrected. Maxillary expansion was guided by a transpalatal bone-anchored device (TPD). Expansion measurements were made 1-2 months before surgery, 6 and at least 12 months after surgery. The transverse occlusion was corrected in all cases. After 12 months the gingival landmarks revealed an expansion range from -0.83 to +2.92 mm for the cuspids, +1.66 to +6.23 mm for the bicuspids and from +2.68 to +4.80 mm for the molars. For the occlusal landmarks, expansion ranged from -2.01 to +3.15 mm (cuspids), from +1.11 to +7.13 mm (bicuspids) and from +2.70 to +6.26 mm (molars). Cuspid expansion was significantly smaller than that of bicuspids and molars. This more posterior expansion was achieved through the surgical procedure. The transverse stability obtained with the aid of the bone-anchored TPD was satisfying. This preliminary study supports the principle of an original surgical approach, called 'Le Fort I--TPD', which combines a Le Fort I osteotomy with a controlled maxillary expansion.

Decompressive craniectomy in a case of intractable intracranial hypertension due to pneumococcal meningitis.

A young woman suffering from S. pneumoniae meningitis developed intractable intracranial hypertension with a GCS of 3. Intracranial pressure (ICP) ranged above 30 mmHg despite maximal medical treatment and continuous CSF drainage. We performed a wide bilateral decompressive craniectomy (DC) with duraplasty and we observed an immediate and stable drop of her ICP. When discharged she was independent. DC has been rarely used to control ICP in encephalitis patients and recently only in one case of meningitis. This operation could be a valuable option when all other measures to decrease ICP have failed; when necessary, it should be performed according to some rules otherwise it could be harmful for the patient. Conclusive data on the impact of DC on the final outcome of such patients are not available yet.

Switching to etanercept in patients with rheumatoid arthritis with no response to infliximab.

TNF-alpha is thought to play a pivotal role in the initiation and perpetuation of the chronic inflammatory process in rheumatoid arthritis. TNF-alpha blockers such as infliximab and etanercept are currently used in the treatment of active rheumatoid arthritis (RA) when traditional DMARDs have failed and are effective in a significant proportion of patients. However, about one third are non-responders to anti-TNF-alpha. The aim of this study was to verify whether rheumatoid patients, after failing infliximab, can benefit from etanercept. We analysed 18 patients with active RA with no response to at least 3 DMARDs and where infliximab therapy had failed. The patients had received infliximab associated with methotrexate: eleven of them did not show any significant response, while seven patients, after a good response, relapsed. Etanercept was then started. EULAR criteria of response were used with calculation of activity index DAS28 at baseline, after 2 weeks, 3 months and every third month until last follow-up. A moderate or good response was achieved with etanercept in 13 out of 18 patients. From our experience, etanercept can be considered as a good alternative choice when infliximab has failed.

Activation of endogenous neural stem cells in the adult human brain following subarachnoid hemorrhage.

In the adult human brain, the presence of neural stem cells has been documented in the subgranular layer of the dentate gyrus of the hippocampus and in the subventricular zone of the lateral ventricles. Neurogenesis has also been reported in rodent models of ischemic stroke, traumatic brain injury, epileptic seizures, and intracerebral or subarachnoid hemorrhage. However, only sparse information is available about the occurrence of neurogenesis in the human brain under similar pathological conditions. In the present report, we describe neural progenitor cell proliferation in the brain of patients suffering from subarachnoid hemorrhage (SAH) resulting from ruptured aneurysm. Ten cerebral samples from both SAH and control patients obtained, respectively, during aneurysm clipping and deep brain tumor removal were analyzed by reverse transcription followed by polymerase chain reaction (RT-PCR) and/or immunohistochemistry (IHC). In tissue specimens from SAH patients, RT-PCR and IHC revealed the expression of a variety of markers consistent with CNS progenitor cells, including nestin, vimentin, SOX-2, and Musashi1 and -2. In the same specimens, double immunohistochemistry followed by confocal analysis revealed that Musashi2 consistently colocalized with the proliferation marker Ki67. By contrast, no such gene or protein expression profiles were detected in any of the control specimens. Thus, activation of neural progenitor cell proliferation may occur in adult human brain following subarachnoid hemorrhage, possibly contributing to the promotion of spontaneous recovery, in this pathological condition.

[Interceptive treatments (ages 6-10) of transverse deformities: posterior crossbite]. / Traitements interceptifs (6-10 ans) des dysmorphies transversales: l'articulé croisé postérieur.

By means of a review of the literature, the authors argue the case for early treatment of posterior cross bites. They outline the particularities and advantages of various therapeutic techniques including grinding down the interfering cusps of deciduous canines and palatal expansion in the mixed dentition.

[Maxillary transversal expansion obtained by transpalatal distractor and Le Fort I osteotomy with posterior impaction of the maxilla, in one stage]. / Expansion maxillaire assistée par distracteur tranpalatin et ostéotomie de Le Fort I d'impaction postérieure, en un seul temps.

INTRODUCTION: The transpalatal distractor (TPD", Surgi-Tec, Bruges, Belgium) is a bone support device whose transversal expansion effect is well known in teenagers at the end of their growth and in adults. Surgical assisted rapid palatal expansion is usually carried out before the orthodontic treatment phase. The transversal gain is mainly seen at the anterior level, and can avoid, in some cases, extraction of bicuspids. It is difficult to correct a sizeable posterior transversal deficit using this technique, and patients presenting a complex dismorphosis must go through a second surgical phase to correct the vertical and sagittal abnormalities at the end of the orthodontic preparation. OBSERVATION: We describe a clinical case of posterior transversal surgical expansion, associated with posterior impaction of the maxilla, in one stage, at the end of orthodontic preparation. The osteotomies, the positioning of the distractor and the orthodontic apparatus enable the palatal transversal expansion to be modulated as required. DISCUSSION: The advantages and limitations of this therapeutic technique are discussed.

Cooperative study by the Italian neuroendoscopy group on the treatment of 61 colloid cysts.

OBJECTS: Microsurgical resection, stereotactic aspiration and VP shunt have for years been the choice options for the treatment of colloid cysts of the third ventricle. Recently, endoscopic approaches have aroused increasing interest and gained acceptance. Although safer, this minimally invasive approach is considered less efficacious than microsurgery. Relatively long-term results are now available and some conclusions might be inferred on the usefulness of this procedure. MATERIALS AND METHODS: Between 1994 and 2005, 61 patients harbouring a colloid cyst of the third ventricle were treated with neuroendoscopic technique in 11 Italian neurosurgical centres. Cyst diameters ranged from 6 to 32 mm. A flexible endoscope was used in 34 cases, a rigid one in 21, both instruments in six. The technique consisted in cyst fenestrations, colloid aspiration, coagulation of the internal cyst wall and, occasionally, capsule excision. Mean postoperative hospital stay was 6.7 days. Early postoperative neuroimaging revealed a cyst residue in 36 cases (mean diameter 4.3 mm). There were two complications (3.2%). Follow-up varied between 1 and 132 months (mean 32 months, more than 5 years in 17 patients). There were seven asymptomatic recurrences, three of them evolving from a previous residue. CONCLUSION: The endoscopic approach to the treatment of colloid cysts is safe, effective and well accepted by patients. Although asymptomatic, recurrences (11.4%) cast a persisting shadow on the long-term results, and, therefore, the controversy with the traditional microsurgical treatment remains open.

Endoscopic treatment of brain abscesses.

BACKGROUND: Stereotactic aspiration with external drainage has become widely accepted as the standard treatment for intracerebral abscesses. Although neuroendoscopic technique has only been occasionally adopted for this pathology, it introduces some advantages because it presents visual awareness that the pus has been removed. METHODS: Four patients with cerebral abscess and one with a subdural empyema were operated using a neuroendoscopic technique in our Department between 1996 and 2003. A 4-mm flexible endoscope was introduced into the purulent collection through a burr hole, the pus was meticulously aspirated, and the cavity washed with isovolumetric antibiotic lavages using the working channel for both irrigation and suction. CONCLUSION: Neuroendoscopic treatment of brain abscesses presents some additional advantages as a possible alternative to stereotactic aspiration, which still constitutes the gold standard for this pathology. The adoption of stereotactic or frameless guidance systems can probably be recommended particularly for deep, complex lesions.

Efficacy of cyclosporin-A in the long-term management of thrombocytopenia associated with systemic lupus erythematosus.

Thrombocytopenia frequently complicates systemic lupus erythematosus (SLE), and its long-term management may be problematic. Intravenous immunoglobulins and high doses of steroids are often effective as induction therapy, but thrombocytopenia frequently relapses during steroid tapering. Several immunosuppressive agents have been evaluated as induction or maintenance therapy in small series or in case reports. We describe six consecutive unselected SLE patients where cyclosporin-A (CyA) was effective and safe in the long-term management of thrombocytopenia and allowed steroid tapering. One relapse occurred during CyA reduction and responded to CyA dose adjustment. Steroids could be stopped in three out of six patients, and were maintained at very low doses in the remaining patients. CyA was stopped in one patient after one year of treatment, without relapse at month 11+ from discontinuation. No severe side effects were documented. Overall, these data suggest that CyA may prove to be an effective and safe therapeutic option for SLE-related thrombocytopenia.

Phase II study of pegylated liposomal doxorubicin and oxaliplatin in relapsed advanced ovarian cancer.

OBJECTIVE: This phase II study evaluated the efficacy and safety of pegylated liposomal doxorubicin (PLD) 30 to 35 mg/m(2) plus oxaliplatin 70 mg/m(2) every 28 days in women with advanced ovarian cancer that recurred or progressed after a platinum-based regimen. METHODS: 43 women received a median of 6 courses of treatment. RESULTS: Objective response was 54% in the evaluable population and was higher in women with platinum-sensitive (67%) compared with platinum-resistant disease (29%). At a median duration of follow-up of 15.5 months, median overall survival was 15.8 months and time to tumor progression 7.3 months. Most toxicity was no greater than grade 1 or 2. There was no grade 3 or 4 palmar-plantar erythrodysesthesia. After 264 cycles administered, neutropenia was the most common cause of severe toxicity and required one patient to withdraw from the study. No cardiotoxicity was reported. CONCLUSION: PLD plus oxaliplatin is active and well tolerated in women with relapsed advanced ovarian cancer, regardless of platinum sensitivity.

Endoscopic selective sampling of human ventricular CSF: a new perspective.

Neuroendoscopy has achieved extensive acceptance among neurosurgeons as a minimally invasive technique for the treatment of patients affected by blocked hydrocephalus. During endoscopic procedures minimal CSF amounts from selected anatomic sites of the ventricles can be withdrawn. Steerable endoscopes are used and their flexibility facilitates the aspiration of CSF during the preliminary inspection through the ventricular cavities, without any interference with the surgical actions or additional risks for the patients. In this preliminary study the concentrations of melatonin and other related metabolites in the lateral ventricles, third ventricle, pineal recess and infundibular recess were examined. The data obtained from a patient affected by blocked hydrocephalus confirmed a constant and significant difference of concentration of these substances, for instance, melatonin levels were found to be much higher in the third ventricle (542 pg/mL in its centre) than in the lateral ventricle (172 pg/mL in the right ventricle). Nevertheless, instead of what we would expect, the highest melatonin concentrations were not found in the pineal recess (438 pg/mL). In the future, neuroendoscopy, beside its evident therapeutic efficacy, could open new perspectives in the study of both CSF biochemistry and physiology, allowing a highly selective approach to the various substances which are released and float in it.

Surveillance of screening for hepatitis C through the laboratory network RENA-VHC, France, 2000-2001.

Over the period 2000-2001, 189 private or hospital laboratories scattered throughout France participated to the laboratory network RENA-VHC. A total of 759 591 serologies (screening tests and validation of screening tests) were performed, revealing an increase of 10% between 2000 and 2001. The rate of the amount of tests to validate screening found positive over the overall amount of tests performed was 1.2% in 2000 and 1.0% in 2001. This suggests that screening covered more people with little risk of acquiring HCV infection. The per-sons confirmed HCV positive were predominantly men (sex ratio 1.5) of which 31% were 30 to 39 years of age.

[A multidisciplinary approach to orthognathic surgery]. / Approche pluridisciplinaire de la chirurgie orthognathique.

Orthodontists are precisely aware of their therapeutic limits in dealing with maxillofacial dysmorphia. Unstable results and iatrogenic lesions caused by alveolo-dental compensations for displacements of the skeletal base have convinced them of the importance of orthognathic surgery as a complement to their orthodontic treatments. Collaboration between the orthodontist and the maxillofacial surgeon begins as of the moment a displacement of the skeletal bases is established through clinical and cephalometric diagnosis. Due to factors related to their age and dental history, it is necessary to complement the therapeutic provision for adult patients with the provision of a multidisciplinary team. The dentist and the family doctor take part in the decision regarding the treatment to be administered, they provide advice to their patients and treat them according to the chosen therapeutic sequence. Other practitioners are involved, including the physiotherapist or speech therapist, depending on the clinical requirements. This multidisciplinary approach and collaboration are conducive to the quality of the results and patient satisfaction.
