It is the policy at the Jordan University Hospital to perform lumbar puncture on children with gastroenteritis who present with one or more of the following: age less than 1 month, convulsions, hypoactivity or marked irritability, and depressed sensorium. Review of the records of 737 children admitted with gastro-enteritis between January 1980 and October 1984 showed that lumbar puncture was performed on 351 (47.6%) children. Acute bacterial meningitis was diagnosed in only three children, two of whom had already received treatment before admission and the third had obvious meningeal signs. These findings do not justify the present policy on lumbar puncture in children with gastroenteritis and it is proposed that the procedure be reserved for children in whom abnormal CNS findings persist after initial correction of fluid and electrolyte balance or with overt signs of meningitis.

Uncommon headache syndromes can be classified into two broad categories: (1) urgent conditions, including subarachnoid hemorrhage, giant cell arteritis and bacterial meningitis, and (2) special syndromes, such as cluster headache, migraine with aura and headache caused by benign intracranial hypertension. In this article, uncommon headaches are differentiated from the common migraine and the tension headache, which fall into a third category. If a neurologic abnormality is detected during the physical examination, aggressive medical diagnostic intervention is required. Because of its cost, neuroimaging should be reserved for specific situations that herald life-threatening or acutely reversible conditions; it should not be used in the work-up of nonspecific headache. The diagnosis of common headaches can be simplified by considering tension and common migraine syndromes to exist at different points on a headache spectrum.

The evolution of the endoscopic endonasal transsphenoidal technique, which was initially reserved only for sellar lesions through the sphenoid sinus cavity, has lead in the last decades to a progressive possibility to access the skull base from the nose. This route allows midline access and visibility to the suprasellar, retrosellar and parasellar space while obviating brain retraction, and makes possible to treat transsphenoidally a variety of relatively small midline skull base and parasellar lesions traditionally approached transcranially. We report our current knowledge of the endoscopic anatomy of the midline skull base as seen from the endonasal perspective, in order to describe the surgical path and structures whose knowledge is useful during the operation. Besides, we describe the step-by-step surgical technique to access the different compartments, the "dangerous landmarks" to avoid in order to minimize the risks of complications and how to manage them, and our paradigm and techniques for dural and bony reconstruction. Furthermore, we report a brief description of the useful instruments and tools for the extended endoscopic approaches. Between January 2004 and April 2006 we performed 33 extended endonasal approaches for lesions arising from or involving the sellar region and the surrounding areas. The most representative pathologies of this series were the ten cranioparvngiomas, the six giant adenomas and the five meningiomas; we also used this procedure in three cases of chordomas, three of Rathke's cleft cysts and three of meningo-encephaloceles, one case of optic nerve glioma, one olfactory groove neuroendocrine tumor and one case of fibro-osseous dysplasia. Tumor removal, as assessed by post-operative MRI, revealed complete removal of the lesion in 2/6 pituitary adenomas, 7/10 craniopharyngiomas, 4/5 meningiomas, 3/3 Rathke's cleft cyst, 3/3 meningo-encephalocele. Surgical complications have been observed in 3 patients, two with a craniopharyngioma, one with a clival meningioma and one with a recurrent giant pituitary macroadenoma involving the entire left cavernous sinus, who developed a CSF leak and a second operation was necessary in order to review the cranial base reconstruction and seal the leak. One of them developed a bacterial meningitis, which resolved after a cycle of intravenous antibiotic therapy with no permanent neurological deficits. One patient with an intra-suprasellar non-functioning adenoma presented with a generalized epileptic seizure a few hours after the surgical procedure, due to the intraoperative massive CSF loss and consequent presence of intracranial air. We registered one surgical mortality. In three cases of craniopharyngioma and in one case of meningioma a new permanent diabetes insipidus was observed. One patient developed a sphenoid sinus mycosis, cured with antimycotic therapy. Epistaxis and airway difficulties were never observed. It is difficult todav to define the boundaries and the future limits of the extended approaches because the work is still in progress. Such extended endoscopic approaches, although at a first glance might be considered something that everyone can do, require an advanced and specialized training.

Acute bacterial meningitis is a common neurological emergency and a leading cause of death and neurological disability worldwide. Diagnosis is based on clinical and microbiological findings with neuroimaging in the form of CT reserved for those with specific adverse clinical features or when an underlying cause such as mastoiditis is suspected. MRI is extremely useful for detecting and monitoring the complications of meningitis. These can be remembered by the mnemonic HACTIVE (hydrocephalus, abscess, cerebritis/cranial nerve lesion, thrombosis, infarct, ventriculitis/vasculopathy and extra-axial collection). Diffusion weighted imaging (DWI) and magnetic resonance spectroscopy (MRS) are useful to distinguish abscess from other ring enhancing lesions.

We conducted a retrospective chart review to characterize the outcomes of 12 patients-9 men and 3 women, aged 21 to 79 years (mean: 49)-who had been treated at our tertiary care center for acute bacterial meningitis caused by acute otitis media (ABMAO). Fever was the most common presenting sign/symptom, observed in 8 patients, followed by otalgia, neck stiffness, headache, and confusion. An opaque and bulging tympanic membrane was observed in 8 patients. Cultures were positive for Streptococcus pneumoniae in the cerebrospinal fluid, ear, and blood in 7, 5, and 3 patients, respectively. Immediate treatment included tympanocentesis, with aspirates sent for bacteriologic cultures. Seven patients (58.3%) underwent surgery; 5 were operated on early, and 2 underwent surgery at a later stage because of a suspected defect in the mastoid bone. A cortical mastoidectomy was performed in 6 of the 7 surgical patients; the remaining patient underwent a canal-wall-down procedure. Ten patients experienced a full recovery, 1 died, and 1 had a poor neurologic outcome (vegetative state); both of the latter 2 patients were older than 60 years. We conclude that early diagnosis, administration of antibiotics, and myringotomy are crucial for control of ABMAO. A cortical mastoidectomy with ventilation tube insertion can be reserved for patients who do not respond, which is common.
