Thoughts and concerns of patients at hospital discharge after lumbar spine surgery. A qualitative study.

PURPOSE: The increased rate of surgical interventions point to the necessity to investigate the patient's experience from a biopsychosocial perspective. The aim of this study was to investigate the thoughts and concerns of patients undergoing spinal surgery for lumbar degenerative disease at the time of their discharge from hospital. METHODS: Semi-structured interviews were conducted with 28 patients. The questions investigated possible concerns associated to discharging them home. A content analysis was performed by a multidisciplinary group to identify the main themes that emerged from the interviews. RESULTS: The patients were satisfied with the surgeons' preoperative explanations and description of expected prognosis. However, they were disappointed with the lack of information at hospital discharge, in particular regarding practical and behavioral recommendations. The patients expressed clear concerns about being left alone to deal with possible complications or difficulties they may encounter when returning home. CONCLUSION: This study underlined the patients' need for a comprehensive psychological guidance and possibly a person of reference during the post-operative process. Discussing discharge with the patient was emphasized as an important issue to improve patients' compliance to the recovery process itself. Putting these elements into practice should help spine surgeons to manage better hospital discharge.IMPLICATIONS FOR REHABILITATIONA comprehensive discussion with the patient at the time of hospital discharge is clearly stressed as an important issue to improve patients' adherence to the recovery process.The patients complained of a lack of information when returning home, in particular regarding practical and behavioral recommendations.The patients expressed clear concerns about possible complications or difficulties they may encounter when returning home and they expressed their need to know whom they can contact for help if needed.A better understanding of the thoughts and concerns of patients undergoing spinal surgery at the time of their discharge from hospital should help spine surgeons to improve the management of hospital discharge and the post-operative recovery.

Dietary cyanidin 3-glucoside from purple corn ameliorates doxorubicin-induced cardiotoxicity in mice.

BACKGROUND AND AIMS: Anthracyclines are effective anticancer drugs that have improved prognosis of hundred thousand cancer patients worldwide and are currently the most common chemotherapeutic agents used for the treatment of blood, breast, ovarian and lung cancers. However, their use is limited because of a cumulative dose-dependent and irreversible cardiotoxicity that can cause progressive cardiomyopathy and congestive heart failure. Aim of the present study was to determine the cardioprotective activity of a dietary source of cyanidin 3-glucoside (C3G), such as purple corn, against doxorubicin (DOX)-induced cardiotoxicity in mice. METHODS AND RESULTS: In vitro studies on murine HL-1 cardiomyocytes showed that pretreatment with both pure C3G and purple corn extract improved survival upon DOX treatment. However, C3G and purple corn extract did not affect the cytotoxic effect of DOX on human cancer cell lines. We then validated in vivo the protective role of a C3G-enriched diet against DOX-induced cardiotoxicity by comparing the effect of dietary consumption of corn isogenic lines with high levels of anthocyanins (purple corn - Red diet - RD) or without anthocyanins (yellow corn - Yellow diet - YD) incorporated in standard rodent diets. Results showed that mice fed RD survived longer than mice fed YD upon injection of a toxic amount of DOX. In addition, ultrastructural analysis of hearts from mice fed RD showed reduced histopathological alterations. CONCLUSION: Dietary intake of C3G from purple corn protects mice against DOX-induced cardiotoxicity.

Isthmocele in a retroflexed uterus: a report of an unrecognized case.

The term "isthmocele" refers to a niche on the anterior wall of the uterine isthmus or of the cervical canal at the site of a previous cesarean delivery scar. Such anatomic defect can cause many gynecologic sequelae that only recently have being identified and described. Hysteroscopy is commonly considered the gold standard for the diagnosis and also for the treatment, at least in the case of defects of small size. The authors described the case of a 37-year-old woman who underwent a cesarean section (CS) seven years before, with a long lasting history of menstrual irregularities, and pelvic pain increasing during menstruation at the hypogastric level. Magnetic resonance imaging (MRI) showed an exceptionally large isthmocele on the anterior wall of a retroflexed uterus which was otherwise misinterpreted as the uterine cavity filled with menstrual blood during a previous hysteroscopy (HSC). Although exceptional, this case highlights the possibility that a large sized isthmocele in a retroflexed uterus could be misinterpreted as the uterine cavity filled by menstrual blood at HSC. In this case MRI definitely clarified the diagnosis.

MRI in the assessment of prolapsed pedunculated submucous leiomyomas: two case reports.

Uterine leiomyomas are the most common benign gynecological tumors affecting 20-30% of women in reproductive age. Despite their benignity, in some cases several symptoms may require surgical intervention. Submucosal leiomyomas are less frequent (5-10%), but are usually symptomatic. Approximately 2.5% of the myomas are pedunculated and can protrude in the cervical canal. Symptomatic leiomyomas can be treated either by hysterectomy or myomectomy, and these procedures can be performed with several techniques. Whenever possible, hysteroscopic myomectomy is better because it has many advantages, as it also preserves future fertility. Two interesting cases of prolapsed pedunculated submucous leiomyomas are reported in order to prove that magnetic resonance imaging (MRI) is essential to choose the most appropriate treatment and to perform an adequate presurgical planning, which must be based on an overall assessment of the leiomyoma's characteristics (number, location, size and presence or absence of a stalk) and the patient's characteristics.

Early versus delayed laparoscopic cholecystectomy for acute cholecystitis.

AIM: Laparoscopic cholecystectomy, currently the gold standard treatment for cholelithiasis, has been extended to treating acute cholecystitis as well. However, operation timing remains controversial. The aim of this retrospective study was to compare our data on the timing of surgery for early and delayed laparoscopic cholecystectomy for acute cholecystitis. METHODS: From January 1, 2006 to December 31, 2010, 508 laparoscopic cholecystectomy procedures were performed, 149 of which for acute cholecystitis: 122 operations were defined as early (performed within 72 hours of symptom onset) and 27 as delayed (72 hours to 9 days from symptom onset). RESULTS: There were no statistically significant differences in operating time, conversion or complications rates between early and delayed procedures. The total length of hospital stay was longer for patients who had undergone a delayed procedure. The success rates were similar irrespective of the surgeon's level of experience. CONCLUSION: Patients operated on for acute cholelithiasis between 72 hours and up to 9 days after symptom onset may benefit similarly as from an earlier operation. Delayed laparoscopic cholecystectomy for acute cholelithiasis is a feasible and safe procedure that compares favorably with early laparoscopic cholecystectomy.

Molecular MR imaging for the evaluation of the effect of dynamic stabilization on lumbar intervertebral discs.

The dynamic stabilization of lumbar spine is a non-fusion stabilization system that unloads the disc without the complete loss of motion at the treated motion segment. Clinical outcomes are promising but still not definitive, and the long-term effect on instrumented and adjacent levels is still a matter of discussion. Several experiments have been devised in order to gain a better understanding of the effect of the device on the intervertebral disc. One of the hypotheses was that while instrumented levels are partially relieved from loading, adjacent levels suffer from the increased stress. But this has not been proved yet. The aim of this study was to investigate the long-term effect of dynamic stabilization in vivo, through the quantification of glycosaminoglycans (GAG) concentration within instrumented and adjacent levels by means of the delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC) protocol. Ten patients with low back pain, unresponsive to conservative treatment and scheduled for Dynesys implantation at one to three lumbar spine levels, underwent the dGEMRIC protocol to quantify GAG concentration before and 6 months after surgery. Each patient was also evaluated with visual analog scale (VAS), Oswestry, Prolo, Modic and Pfirrmann scales, both at pre-surgery and at follow-up. Six months after implantation, VAS, Prolo and Oswestry scales had improved in all patients. Pfirrmann scale could not detect any change, while dGEMRIC data already showed a general improvement in the instrumented levels: GAG was increased in 61% of the instrumented levels, while 68% of the non-instrumented levels showed a decrease in GAG, mainly in the posterior disc portion. In particular, seriously GAG-depleted discs seemed to have the greatest benefit from the Dynesys implantation, whereas less degenerated discs underwent a GAG depletion. dGEMRIC was able to visualize changes in both instrumented and non-instrumented levels. Our results suggest that the dynamic stabilization of lumbar spine is able to stop and partially reverse the disc degeneration, especially in seriously degenerated discs, while incrementing the stress on the adjacent levels, where it induces a matrix suffering and an early degeneration.

Efficacy of treatment with percutaneous vertebroplasty and kyphoplasty for traumatic fracture of thoracolumbar junction.

AIM: The aim of this paper was to assess the efficacy of a minimally invasive treatment with percutaneous vertebroplasty and kyphoplasty for traumatic fracture of thoracolumbar junction. Treatment of stable traumatic vertebral fractures of the thoracolumbar junction without neurological deficit is still controversy. Conservative treatment, characterized by discomfort and limitation in patient mobility, was progressively replaced by minimally invasive techniques such as percutaneous vertebroplasty and kyphoplasty. METHODS: Between January 2003 and August 2005, 34 patients suffering from 42 thoracolumbar fractures were treated at Neurosurgical Department of Istituto Galeazzi (Milan). The treatment selected (vertebroplasty versus kyphoplasty), depended on age of patients, timing and type of fracture. Results were clinically assessed by Visual Analogue Score (VAS) and Oswestry Disability Index. RESULTS: Mean preoperative VAS was 8.32 (range 5-10). Percutaneous vertebroplasty was performed in 25 cases (73.5%); while 9 patients were treated by kyphoplasty (27.5%); 27 patients showed a single level and 7 multilevel of the fractures. No complications occurred (infection, neurological deficit, embolic events) after treatment. At the early follow-up 91.7% of the patients achieved a good pain control already after 24 hours. Pain relief and disability, analyzed by VAS and Oswestry Disability Index, showed a good results at late follow-up time. CONCLUSIONS: Percutaneous vertebroplasty and kyphoplasty are two safe and effective techniques for treatment of thoracolumbar traumatic fractures and allow a good pain-control and return to normal working activity and social life.

Symptomatic pineal cyst: case report and review of the literature.

Asymptomatic cysts of the pineal region are common incidental findings in adults. In contrast, symptomatic pineal cysts are rare and their management is not well defined. We present the case of a 39-year-old woman suffering from intracranial hypertension, with visual disturbance and mild papilledema. The MR images showed a voluminous cyst of the pineal region responsible for an obstructive hydrocephalus. Endoscopic treatment with the aid of computerized neuronavigation consisting in third ventriculostomy and fenestration of the cyst was performed. Intracranial hypertension symptoms resolved in 24 hours. The one year follow-up cerebral MR images demonstrated the normalization of ventricular size with patency of the aqueduct of Sylvius. Reviewing the literature demonstrates that the endoscopic approach represents a minimally invasive and safe procedure in the treatment of symptomatic pineal cysts.

Effect of ovaric hyper-stimulation on blood lymphocyte subpopulations, cytokines, leptin and nitrite among patients with unexplained infertility.

PROBLEM: To determine the effect of ovarian stimulation on TH1, TH2 and natural killer (NK) lymphocytes, plasma cytokines, leptin and nitrite levels. METHODS: Women with reproductive failure were studied during the implantation window, at baseline (n = 18) and under ovarian stimulation (gonadotropins + progesterone, n = 6). CONTROLS: eight fertile women. Lymphocyte subpopulations and NK function were determined by flow cytometry. Interleukin-2 (IL-2), IL-4, IL-10, IFN-gamma, TNF-alpha, TGF-beta1 and leptin were measured by enzyme immunoassay (EIA); nitrite by the Griess reaction. RESULTS: At baseline, patients had higher values of NK effectors, NK activity and plasma IFN-gamma and IL-2 than controls. Conversely, TGF-beta1 values were lower. Hormones induced leukocytosis. Under stimulation, THI CD4+ cells, NK effectors and function and plasma IFN-gamma and IL-2 decreased, while transforming growth factor (TGF)-beta1 increased. Other variables did not change. CONCLUSION: The abnormal distribution of leukocytes, high TH1 cytokines and a low TGF-beta1 associated with reproductive failure, respond to ovarian stimulation, achieving total or partial normalization.
