Posterior Cervical Transfacet Fusion with Facetal Spacer for the Treatment of Single-Level Cervical Radiculopathy: A Randomized, Controlled Prospective Study
Delayed intraparenchymal hematoma following diagnostic lumbar puncture
Lumbar puncture is a safe and commonly performed procedure, with an overall complication rate of 0.1% to 0.5%. Well-known contraindications to lumbar puncture are an intracranial tumor, noncommunicating hydrocephalus, coagulopathy, and ruptured aneurysm with subarachnoid hemorrhage. We report a case of a young man with epilepsy who, after a lumbar puncture performed for research purposes, presented with an intracerebral hematoma and neurological deficits. To the best of our knowledge, post-tap intraparenchymal hematoma is extremely rare and only 1 case has been reported previously. In consideration, all patients undergoing a lumbar puncture should be informed about this possible rare complication, even in the absence of documented hemorrhagic risk factors
Disseminated Cerebrospinal Embryonal Tumor in the Adult
Introduction. According to the 2016 World Health Organization classification of Tumors of the Central Nervous System, the term Primitive Neuroectodermal Tumor has been replaced by the term Embryonal Tumor (ET). We present a case of disseminated cerebrospinal ET presenting in an adult patient. Illustrative Case. A 49-year-old male presenting with low back pain, dysuria, and hypoesthesia of the lower extremities referred to our emergency department. Brain and whole spine contrast-enhanced MRI documented a diffusively disseminated heterogeneous neoplasm with intradural extra- and intramedullary involvement of the cervicothoracic tract and cauda equina. A primary biopsy of the lumbosacral localization was performed through L5 bilateral laminectomy. Histologic diagnosis was Embryonal Tumor Not Otherwise Specified. The patient underwent chemotherapy with postoperative adjuvant alternating Vincristine-Doxorubicin-Ifosfamide (VAI) and Ifosfamide-Etoposide (IE). Discussion. Spinal ETs are exceedingly rare especially when presenting in the adult patient. Neurosurgical and oncologic management is still unclear. When feasible, surgical removal should always be performed to obtain a histologic diagnosis. Postoperative adjuvant therapy might entail both chemo- and radiotherapy; however a consensus on this matter is still lacking
Lumbar Endoscopic Microdiscectomy:Where Are We Now? An Updated Literature Review Focused on Clinical Outcome, Complications, and Rate of Recurrence
Endoscopic disc surgery (EDS) for lumbar spine disc herniation is a well-known but developing field, which is increasingly spreading in the last few years. Rate of recurrence/residual, complications, and outcomes, in comparison with standard microdiscectomy (MD), is still debated and need further data. We performed an extensive review based on the last 6 years of surgical series, systematic reviews, and meta-analyses reported in international, English-written literature. Articles regarding patients treated through endoscopic transforaminal or interlaminar approaches for microdiscectomy (MD) were included in the present review. Papers focused on endoscopic surgery for other spinal diseases were not included. From July 2009 to July 2015, we identified 51 surgical series, 5 systematic reviews, and one meta-analysis reported. In lumbar EDS, rate of complications, length of hospital staying, return to daily activities, and overall patients’ satisfaction seem comparable to standard MD. Rate of recurrence/residual seems higher in EDS, although data are nonhomogeneous among different series. Surgical indication and experience of the performing surgeon are crucial factors affecting the outcome. There is growing but still weak evidence that lumbar EDS is a valid and safe alternative to standard open microdiscectomy. Statistically reliable data obtained from randomized controlled trials (better if multicentric) are desirable to further confirm these results
Pleomorphic rhabdomyosarcoma of the cerebellopontine angle in an adult: a review of literature.
Rhabdomyosarcoma (RMS) is a rare and aggressive neoplasm characterised by rapid growth and metastatic invasion. The most frequent localisation is the skeletal musculature of the limbs. The head and the neck are rarely involved. A 50-year-old woman presented to our attention because of a progressively increasing headache, ataxia and vomiting. MRI showed a lesion at the right cerebellopontine angle. Thereafter, the patient was submitted to a piece-meal removal of the neoplasm. Despite the postoperative MRI showed no signs of remnant, 7 months after the surgery, the disease recurred with multiple localisations, and the patient died a few days later. This report is the first description in the literature of a pleomorphic RMS of the cerebellopontine angle. This particular tumour carries a bad prognosis because of the vicinity of nervous structures and of the impossibility of achieving a one-piece resection. More than ever, the adjunctive treatments had to be effective against a potential remnant and in controlling recurrences.©2014 BMJ Publishing Group. All rights reserved
Epidural hematoma with detachment of the dural sinuses
Epidural hematoma (EH) is a neurosurgical emergency that requires early surgical treatment. It is rarely extended bilaterally causing a detachment of the dural sinus or sinuses. The authors present two rare cases of EH with dural sinus detachment and describe how they suspend them. In these cases it is crucial to firmly suspend the dura mater and the dural sinus to the inner skull surface to prevent postoperative rebleeding
ANALYSIS OF HOSPITAL ANTIBIOTIC PRESCRIPTIONS AFTER THE IMPLEMENTATION OF STEWARDSHIP: A RETROSPECTIVE OBSERVATIONAL STUDY IN TWO HOSPITALS IN NORTH-EASTERN SICILY
Introduction: Antimicrobial resistance is a global problem caused by the inappropriate use of antibiotics. To combat this phenomenon, multidisciplinary antimicrobial stewardship programmes have been initiated, the primary objectives of which include improving both the level of appropriateness of prescription and clinicians’ awareness of the correct use of antibiotics.
Objective/Purpose: The objective of the work was to conduct an analysis of antibiotic consumption at hospital level to assess the appropriateness of antibiotic prescription in a number of Operational Units.
Method: From 01/01/2021 to 31/12/2022, data were extracted from the Pharmacy Operational Unit’s management software on the dispensing of antibiotics (injectable and oral use), the Defined Daily Doses, and the number of dosage units dispensed to the General Medicine, Intensive Care, General Surgery and Neurorehabilitation Operational Units of two hospitals.
Results: Total antibiotic consumption was 7,845 dosage units in 2021 and 10,182 in 2022. The comparison of the defined daily dose values (4,565,485 in 2021 and 5,079,671 in 2022) is indicative of the use of antibiotics with different dosages, with a percentage increase of 11.3%. A comparison was also made between the Defined Daily Doses/100 bed-days delivered in 2021 and the regional and national figures, yielding a significantly lower figure than these latter figures.
Conclusions: The loss of antibiotic efficacy threatens to throw healthcare systems into crisis, leading to in an increase in morbidity and mortality from infections. The implementation of antimicrobial stewardship programmes remains, at present, the best tool to harness in order to curb the phenomenon of antimicrobial resistance. There is therefore a need for increasingly specialised professionals in the field of infectious diseases. Nurses and pharmacists play a crucial role in antimicrobial stewardship programmes, as they collaborate not only in the implementation of antimicrobial guidelines, but also in the review of individual patient regimens in order to optimise treatment and in the training of healthcare personnel on the appropriate use of antimicrobials
Intrathecal Versus Intravenous Morphine in Minimally Invasive Posterior Lumbar Fusion: A Blinded Randomized Comparative Prospective Study
STUDY DESIGN: A blinded, randomized, comparative prospective study.
OBJECTIVE: The aim of this study was to compare the use of intrathecal morphine
to endovenous morphine on postoperative pain after posterior lumbar surgery.
SUMMARY OF BACKGROUND DATA: Intrathecal morphine can provide significant safe
analgesia for at least 12 hours and up to 24 hours in patients undergoing major
surgery. Its dosages have been decreasing in the last 30 years, but currently,
the optimal dose remains unknown. As of today, there are no studies comparing the
efficacy and the side effects of this technique with intravenous morphine
administration after minimally invasive lumbar fusion surgery.
METHODS: We randomized and compared two groups of 25 patients, who were given
either 100 μg intrathecal (ITM group) or 5 ± 2 mg intravenous morphine delivered
intravenously for 24 hours at 2 mL/h (IVM group) after minimally invasive
posterior lumbar fusion. VAS score at 0, 6, 12, 24 hours, mobilization out of bed
at 6 hours, hospitalization duration and complications as lower limbs
paresthesia, urinary retention at 6 and 12 hours, nausea, vomit, itch, and
constipation were evaluated.
RESULTS: Data showed a lower VAS score, a reduction of constipation, lower limbs
paresthesia, or urinary retention at 12 hours in ITM rather than in the IVM
group. None suffered of vomit, itch, or nausea in both groups. Urinary retention
was observed more frequently in ITM group at 6 hours. Patients of ITM group were
mobilized out bed earlier than those from IVM group.
CONCLUSION: A low dosage of intrathecal morphine is safe and effective after
minimally invasive lumbar fusion surgery. The reduction of pain in the study
group permitted a shorter hospitalization and earlier mobilization out of bed,
augmenting patients' comfort.
