OBJECTIVES/HYPOTHESIS The objectives of this study were to examine the presence of β-2 transferrin (β2TRNSF) in cerebrospinal fluid (CSF) contaminated in vitro by various bacteria and explore the mechanism (passive or active) responsible for β2TRNSF elimination. Early diagnosis of CSF leakage may change treatment decisions and minimize the risk of meningitis and encephalitis. β2TRNSF is a prote...

Chronic serous otitis media is a common problem in the daily routine of the otorhinolaryngologist. In the majority of cases, the cause is related to dysfunction of the eustachian tube due to viral or bacterial rhinitis and occasionally to nasopharyngeal tumors. We report a case of a patient presenting with chronic serous otitis media that was resistant to conventional therapy. MRI with gadolini...

Positive contrast cisternography with digital subtraction of fluoroscopy images before computed tomography (CT) was employed in the investigation of eight patients with cerebrospinal fluid (CSF) rhinorrhoea. Fistulae were visualised by preliminary digital subtraction cisternography (DSC) in six patients and in five patients the sites of leakage were confirmed at surgery. Fluoroscopy facilitated...

Cerebrospinal fluid (CSF) leakage is a potential complication of cranial and spinal surgery. Postoperative CSF leakage can induce delayed healing, wound infection and meningitis. DuraSeal® (Covidien, Waltham, MA, USA) is a synthetic product which has been increasingly used to facilitate watertight repair of dural defects after cranial and spinal surgery. Despite some advantages of Duraseal®, th...

Incidental durotomies are a frequent complication during spinal surgery. Cerebrospinal fluid (CSF) leakage from a dural tear may be visually apparent intraoperatively, but occasionally, a tear may not be recognized during the procedure. We report our experience in 2 cases of postoperative incarceration of nerve root as a cause of sciatica, without CSF leakage intraoperatively. When durotomy att...

The unique symptom of intracranial hypotension (IH) is an orthostatic headache caused by low cerebrospinal fluid (CSF) pressure and is not so rare. IH results from loss of CSF caused by a dural defect in the spine, cranial vault, or skull base. The classic orthostatic headache commences within 15 minutes, but occasionally symptoms last up to several hours, after standing or upright sitting posi...

Inflammation and vascular leakage are prevalent in asthma. This study aimed to elucidate the mechanisms involved in serum potentiation of cytokine-induced granulocyte macrophage colony stimulating factor (GM-CSF) production by human airway smooth muscle cells and to identify possible factors responsible. Serum-deprived cells at low density were stimulated with TNF-alpha and IL-1beta for 24 h. H...

Cerebrospinal fluid (CSF) leaks are one of the common complications after traumatic brain injuries (TBI). The risks of CSF leaks can be detrimental to the outcomes of the patients. Early diagnosis and proper management is imperative for it is strongly associated with a better long-term prognosis of the patients. Diagnostic tools for CSF leaks are still under debate. Nevertheless, many reports o...

Muhammad Burhan Ud din Janjua, Inayat Ullah Khan Department of Neurosurgery, Shifa International Hospital, Islamabad, Pakistan. ABSTRACT Objective To present the local experience of fat graft use for sella closure in case of intraoperative CSF leak to prevent the post operative CSF rhinorrhea. Patient and Methods We retrospectively studied 22 cases operated for pituitary adenomas from 2004 to 2...

We report a case of recurrent Streptococcus Pneumoniae meningoencephalitis with a transethmoidal meningoencephalocele (TEME) but without cerebrospinal fluid (CSF) leakage.A 35-year-old man was admitted with S. pneumoniae meningitis. He had suffered from four episodes of recurrent pneumococcal meningitis during the previous 4 years. A computed tomography scan of the paranasal sinus showed the TE...
