ABSTRACT
Introduction:Post-dural puncture headache (PDPH) is defined as an orthostatic headache that develops within the first few days after performing a spinal tap and it is related to extravasation of cerebrospinal fluid (CSF) into the epidural space, resulting in CSF hypovolemia and hypotension. The risk factors for PDPH are not yet fully understood. Objective:To evaluate the risk of spontaneously reported PDPH according to the size and type of spinal tap needle. Methods:A total of 4589 patients undergoing outpatient lumbar puncture (LP) were included. All CSF collections were performed at Senne Liquor Diagnostico, a laboratory specialized in CSF collection and analysis. Patients were instructed to report by telephone if they had orthostatic headache during the first 7 days after LP to the medical team of the laboratory. Patients with previous headache were instructed to report any change in the headache pattern during the same period. Needle gauge was classified into two groups: 1) 25 G or less and 2) greater than 25 G. Two types of needles were used and compared: 1) Pencil point and 2) Quincke. Comparisons of the percentages of spontaneous reports of PDPH were made using the chi-square test. Results:141 patients (3.07%) reported PDPH to the laboratory's medical team. Needles of 25G gauge or less were used in 31.8% of cases. The percentage of patients reporting PHD in the group of 25G or less needles was 1.9% versus 3.6% in the group of larger than 25G needles (p=0.003). Pencil point needles were used in 10.6% of cases. The percentage of PHD among pencil point group was 1.4% versus 3.2% in Quincke group (p=0.026). Conclusion:25 G or finer gauge needles as well as pencil point type needles significantly reduced the risk of spontaneously reported PHD.
Introdução: A cefaleia pós-punção dural (CPPD) é definida como uma cefaleia ortostática que se desenvolve nos primeiros dias após a realização de uma punção lombar e está relacionada ao extravasamento de líquido cefalorraquidiano (LCR) para o espaço peridural, resultando em hipovolemia do LCR e hipotensão. Os fatores de risco para CPPD ainda não são totalmente compreendidos. Objetivo:Avaliar o risco de CPPD relatada espontaneamente de acordo com o tamanho e tipo de agulha de punção lombar. Métodos: Foram incluídos 4.589 pacientes submetidos à punção lombar (PL) ambulatorial. Todas as coletas de LCR foram realizadas no Senne Liquor Diagnostico, laboratório especializado em coleta e análise de LCR. Os pacientes foram orientados a relatar por telefone à equipe médica do laboratório se apresentassem cefaleia ortostática nos primeiros 7 dias após a PL. Pacientes com cefaleia prévia foram orientados a relatar qualquer alteração no padrão de cefaleia durante o mesmo período. O calibre da agulha foi classificado em dois grupos: 1) 25 G ou menos e 2) maior que 25 G. Dois tipos de agulhas foram utilizados e comparados: 1) ponta de lápis e 2) Quincke. As comparações dos percentuais de notificações espontâneas de CPPD foram feitas por meio do teste do qui-quadrado. Resultados:141 pacientes (3,07%) relataram CPPD à equipe médica do laboratório. Agulhas de calibre 25G ou menos foram utilizadas em 31,8% dos casos. A porcentagem de pacientes que relataram HDP no grupo de agulhas 25G ou menos foi de 1,9% versus 3,6% no grupo de agulhas maiores que 25G (p=0,003). Agulhas com ponta de lápis foram utilizadas em 10,6% dos casos. O percentual de DPH no grupo ponta de lápis foi de 1,4% versus 3,2% no grupo Quincke (p=0,026). Conclusão: Agulhas de calibre 25 G ou mais fino, bem como agulhas tipo ponta de lápis reduziram significativamente o risco de HP relatado espontaneamente.
ABSTRACT
Objective@#To describe a makeshift blue light filter for endoscopic visualization of a traumatic cerebrospinal fluid leak repair using intrathecal fluorescein and its application in one patient.@*Methods@# Study Design:Surgical Instrumentation Setting:Tertiary Government Training Hospital Patient:One @*Results@#Intra-operative endoscopic identification of fistulae sites was achieved using intrathecal injection of fluorescein that fluoresced using our makeshift blue light filter in a 43-year-old man who presented with a 3-month history of rhinorrhea due to skull base fractures along with multiple facial and upper extremity fractures he sustained after a fall from a standing height of 6 feet. He underwent transnasal endoscopic repair of cerebrospinal fluid fistulae in the planum sphenoidale, clivus and sellar floor. Post-operatively, there was complete resolution of rhinorrhea with no complications noted. @*Conclusion@#Our makeshift blue light filter made from readily available materials may be useful for endoscopic identification of CSF leaks using fluorescein in a low- to middle-income country setting like ours.

Objective@#To determine the incidence of cerebrospinal fluid (CSF) leak after Hadad[1]Bassagasteguy Flap (HBF) reconstruction after endoscopic endonasal transsphenoidal surgery for skull base pathologies from 2016 to 2020 at the University of the East Ramon Magsaysay Memorial Medical Center. @*Methods@#Design: Case Series. Setting: Tertiary Private Training Hospital.@*Participants@#Charts of 35 patients who underwent endoscopic endonasal transsphenoidal surgery with reconstruction using Hadad-Bassagasteguy flap between January 2016 to February 2020 were reviewed and data on demographics, date of procedure, mass size, final diagnosis, presence of preoperative, intraoperative and postoperative CSF leak, placement of lumbar drain and course in the wards were collected. @*Results@#There were 23 women and 12 men with ages ranging from 21 to 71 years. Four patients (11.4%) had postoperative CSF leak after reconstruction with HBF. Two of these four patients had episodes of nose blowing and sneezing weeks after surgery, prior to the development of the CSF leak. The other two patients experienced CSF leak 3 days postoperatively. @*Conclusion@#HBF has been a workhorse for reconstruction of skull base defects after transsphenoidal surgery, and based on our experience remains to be so, making it possible for expanded approaches and a wide variety of pathologies to be operated on via the endonasal route

Cerebrospinal Fluid LeakABSTRACT
Background: Collagen matrices are effective duraplasty grafts with increasing acceptability. However, little evidences exits for dural reconstruction utilizing monolayer collagen matrix onlay graft in a non-watertight fashion. Purpose of our retrospective analysis was to advance our understanding of the use of semisynthetic collagen as dural substitute in elective cranial surgery.Methods: A consecutive series of sixty patients who underwent elective cranial surgery, where non-watertight dural reconstructions were done with a non-suturable, absorbable collagen matrix onlay graft, has been analysed retrospectively.Results: Overall, the most common indication for duraplasty was tumor resection (93.3%). CSF leak rate was 10.0%. Incidence of aseptic meningitis was 8.3% and all cases has been resolved with steroids alone. Similarly, postoperative surgical site infection rate was 8.3%. Incidence of pseudomeningocele in follow-up was 6.7%. Only in one case (1.7%), permanent CSF (cerebrospinal fluid) diversion was needed due to troublesome CSF leak with associated hydrocephalus.Conclusions: Semisynthetic, monolayer collagen matrix used as an onlay dural graft is a simple, yet an attractive alternative in duraplasty due to their easy handling, lower surgical time, and high biocompatibility, where primary dural closure is undesirable or not feasible. Our study provides greater insight into non-water tight duraplasty procedure. However, further study is needed to determine the optimal strategy for dural reconstruction. Data from this study may be used to compare alternative methods of dural reconstruction in elective cranial surgery.
ABSTRACT
Introducción: La hemorragia cerebelosa remota (RCH, por sus siglas en inglés) después de la cirugía de la columna vertebral es una complicación poco frecuente y se cree que es debida a una pérdida de líquido cefalorraquídeo (LCR) a través de un desgarro dural. Objetivo: Nuestro objetivo es describir un caso de RCH después de una cirugía de columna lumbar, discutir sus posibles mecanismos y revisar la literatura. Material y métodos: Una mujer de 17 años sufrió una caída de altura, presentando luxofractura lumbar sin déficit neurológico. Se realizó descompresión y artrodesis instrumentada. Durante la cirugía se observó un desgarro dural y fuga de líquido cefalorraquídeo. La duramadre desgarrada fue suturada y se dejó un drenaje espinal continuo. Al tercer día postoperatorio evolucionó con disartria y cefalea. La TC de cerebro evidenció una RCH. Resultados: Se retiró el drenaje espinal y la RCH fue tratada de forma conservadora. La paciente fue dada de alta a las 3 semanas sin compromiso neurológico. Conclusión: Aunque la RCH es un evento extremadamente raro, debe tenerse en cuenta como una posible complicación de la cirugía de la columna vertebral, especialmente en operaciones complicadas por desgarros durales.
Introduction: Remote cerebellar hemorrhage (RCH) after lumbar spine surgery is a rare complication and can happen as a result of a cerebro spinal fluid (CSF) leak during surgery. Objective: To describe a case of RCH, discuss the physiopathology and make a review of the literature. Material and methods: A 17 year-old woman presented with a lumbar fracture-dislocation with no neurological déficit after falling from height. A surgical decompression and fusion was performed. During surgery, a dural tear with CSF leakage was found. The tear was sutured and a lumbar drain was placed. 3 days after surgery, the patient presented headaches and dysarthria. Results: The lumbar drain was removed and the RCH was treated conservatively. Patient was discharged 3 weeks after, with no neurological déficit. Conclusion: Although RCH is an extremely rare complication, it should be suspected as a possible complication of spine surgery, specially in surgeries with dural tears.

Background: To study the association of CSF leak in Fronotbasal skull Fractures classified with the Burstein抯 Classification.Methods: A prospective study was conducted from November 2014 to May 2016 in patients admitted with head injuries to KIMSDU, Karad, Maharashtra. All data was retrieved using a standardized data collection form.Results: Out of the total 55 patients of frontobasal fracture, 39 (70.9%) were found to have CSF leak. Out of 39 patients with CSF leak 34 (61.8%) had Type I head injury, 3 (5.5%) had Type II head injury, and 2 (3.6%) had Type III head injury. Statistical analysis showed significant association between CSF leak and Burstein抯 classes of head injury patients (p< 0.05).Conclusions: It was found that patients who had Burstein Type I injuries had a higher chance of CSF leak and most post traumatic leaks could be managed conservatively.
ABSTRACT
@#Introduction: Recurrent pneumococcal meningitis is a relatively rare condition associated with predisposing factors. The objective of the study was to evaluate the characteristics and predisposing factors for recurrent pneumococcal meningitis in adults and compare them to patients with non-recurrent meningitis. Methods: A retrospective record review was performed of all patients hospitalized for pneumococcal meningitis in a large tertiary referral center, during a 10-year period. Results: We identified a total of 194 pneumococcal meningitis episodes in 182 patients. Thirty-eight (20%) meningitis episodes in 26 patients were recurrent. Anatomical defects and/or CSF leakage were present in 55% of recurrent pneumococcal meningitis vs. 10% of non-recurrent episodes (p<0.001). Impaired immune response was encountered in 41% non-recurrent meningitis vs 24% of recurrent episodes (p=0.02). Median age in patients with recurrent meningitis was 29 years, while patients with non-recurrent meningitis had a median age of 57 years (p<0.001). The in-hospital mortality was 3% in patients with recurrent meningitis vs 27% in patients with non-recurrent meningitis (p<0.001). An unfavorable outcome was more likely to occur in patients with advanced age and an impaired immune status. Conclusions: Patients with recurrent pneumococcal meningitis were younger, had less comorbidities and a better outcome
ABSTRACT
OBJECTIVE: The aim of this study was to assess the safety and efficacy of radiation-sterilized allografts of iliac bone and fascia lata from cadaver specimens to repair skull base defects after transsphenoidal surgery. METHODS: Between May 2009 and January 2010, 31 consecutive patients underwent endonasal transsphenoidal surgery and all patients received sellar reconstruction using allografts following tumor removal. The allografts were obtained from the local tissue bank and harvested from cadaver donors. The specimens used in our approach were tensor fascia lata and the flat area of iliac bone. For preparation, allografts were treated with gamma irradiation after routine screening by culture, and then stored at -70degrees C. RESULTS: The mean follow-up period after surgery was 12.6 months (range, 7.4-16 months). Overall, postoperative cerebrospinal fluid (CSF) leaks occurred in three patients (9.7%) and postoperative meningitis in one patient (3.2%). There was no definitive evidence of wound infection at the routine postoperative follow-up examination or during re-do surgery in three patients. Postoperative meningitis in one patient was improved with the use of antibiotics and prolonged CSF diversion. CONCLUSION: We suggest that allograft materials can be a feasible alternative to autologous tissue grafts for sellar reconstruction following transsphenoidal surgery under selected circumstances such as no or little intraoperative CSF leaks.

Cerebrospinal fluid otorrhea is a rare disease entity, especially when brought on by spontaneous causes. The site of leakage should be identified to treat the disorder effectively. Various localizing modality was suggested in the literatures. Intrathecal gadolinium-enhanced magnetic resonance imaging identifies the small leakage site easily and correctly. Hydroxyapatite cement is a calcium phosphate-based material that forms dense paste mixed with water or sodium phosphate solution. Hydroxyapatite cement is remarkable for its excellent biocompatability in interacting with the native bone to osseointergrate with the surrounding bone. We report on our experience of successfully treating a patient with the cerebrospinal fluid leak from the congenital inner ear anomaly using the hydroxyapatite cement.
