A 3 year old child with recurrent pneumococcal meningitis and a congenital cyst of the oval window is presented. An aqueous middle ear effusion was found and scintigraphy demonstrated a middle ear
CSF
leak. Surgical exploration revealed a cyst originating from the stapes footplate. The origin of this malformation is discussed and its possible presence in recurrent mengitis is stressed.

Radicals are species containing one or more unpaired electrons, such as
nitric oxide
(NO.). The oxygen radical superoxide (O2.-) and the nonradical hydrogen peroxide (H2O2) are produced during normal metabolism and perform several useful functions. Excessive production of O2.- and H2O2 can result in tissue damage, which often involves generation of highly reactive hydroxyl radical (.OH) and other oxidants in the presence of "catalytic" iron or copper ions. An important form of antioxidant defense is the storage and transport of iron and copper ions in forms that will not catalyze formation of reactive radicals. Tissue injury, e.g., by ischemia or trauma, can cause increased metal ion availability and accelerate free radical reactions. This may be especially important in the brain because areas of this organ are rich in iron and
CSF
cannot bind released iron ions. Oxidative stress on nervous tissue can produce damage by several interacting mechanisms, including increases in intracellular free Ca2+ and, possibly, release of excitatory amino acids. Recent suggestions that free radical reactions are involved in the neurotoxicity of aluminum and in damage to the substantia nigra in patients with Parkinson's disease are reviewed. Finally, the nature of antioxidants is discussed, it being suggested that antioxidant enzymes and chelators of transition metal ions may be more generally useful protective agents than chain-breaking antioxidants. Careful precautions must be used in the design of antioxidants for therapeutic use.

The present studies were designed to assess the ability of primary cultures of bone marrow cells to produce
nitric oxide
. We found that two inflammatory stimuli, IFN-gamma and LPS, were potent inducers of
nitric oxide
production by bone marrow cells. In addition, the
CSF
granulocyte-macrophage (GM)-
CSF
and IL-3 as well as TNF-alpha, while inactive by themselves, were synergistic with LPS and IFN-gamma in inducing
nitric oxide
production. Maximal effects were observed with combinations of
GM-CSF
and LPS.
Nitric oxide
production by bone marrow cells was found to be dependent on the presence of L-arginine in the culture medium and inhibitable by NG-monomethyl-L-arginine and L-canavanine, two nitric oxide synthase inhibitors.
Nitric oxide
produced by the cells was also suppressed by TGF-beta 1 and the tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate. Separation of bone marrow cells by density gradient centrifugation and flow cytometry revealed that the granulocyte-containing fraction was largely responsible for
nitric oxide
production. In additional experiments we found that treatment of bone marrow cells with
GM-CSF
significantly stimulated bone marrow cell growth. In contrast, the combination of
GM-CSF
and LPS or IFN-gamma markedly suppressed cellular proliferation. This suppression was completely reversed by treatment of the cells with NG-monomethyl-L-arginine. Taken together, these data demonstrate that various inflammatory stimuli and cytokines induce
nitric oxide
production by primary cultures of bone marrow cells and that this mediator may play a role in the regulation of bone marrow cell growth and development.

The audiograms and CT scans of three children with a bilateral congenital mixed deafness are presented. Two children underwent an exploratory tympanotomy revealing a fixed stapes footplate: a perilymph gusher arose during platinotomy in both cases. The gusher was controlled successfully with a large fat graft in both children, and hearing remained unchanged. Two of the children were brothers: they had no other deformities except an enlarged fundus of the auditory canal on CT scans, and no clearly defined bony barrier to the vestibule, suggesting a cerebrospinal fluid fistula. Neither a patent nor an abnormal cochlear aqueduct could be detected in all three cases. It is likely that the three patients present an X-linked mixed deafness syndrome with fixation of the stapedial foot plate and perilymph gusher. A classification of congenital perilymph-
CSF
shunts is proposed.

Trichomonas vaginalis is a parasitic flagellate in the urogenital tract of human. Innate cytotoxicity of macrophages against T. vaginalis has been recognized, but any report on the cytotoxicity of lymphokine-activated macrophages to T. vaginalis is not yet available. The present study aimed to elucidate the lymphokine-activated cell mediated cytotoxic effect against T. vaginalis by mouse peritoneal macrophages. Cytotoxicity was measured by counting the release of 3H-thymidine from prelabeled protozoa, and tested in U-bottom microtiter plates. Nitrite concentration in culture supernatants was measured by standard Griess reaction. The results obtained are as follows: 1. The cytotoxicity of macrophages was increased by addition of rIL-2 or rIFN-gamma. 2. Cytotoxicity of macrophages was reduced by addition of rIL-4 to rGM-
CSF
, rIL-2 or rIFN-gamma. 3. Crude lymphokine mixed with anti-IL-2 decreased the cytotoxicity of macrophages. 4. In case of macrophages cultured with rIFN-gamma or rIL-4, the concentration of nitrite was related with cytotoxicity of macrophages against T. vaginalis, but the cytotoxicity of macrophages cultured with rIL-2 and rIFN-gamma was decreased in spite of its high production of nitrite. From the results obtained, it is assumed that rIL-2 and rIFN-gamma enhance the cytotoxicity of macrophages while rIL-4 inhibits the cytotoxicity against T. vaginalis, and that the production of nitrite does not relate with the cytotoxicity of macrophages, but
nitric oxide
may play a role as an inhibitory factor on the proliferation of T. vaginalis.

CSF
rhinorrhea is called spontaneous if it is due neither to a trauma, nor an intracranial tumour or a congenital malformation. Spontaneous
CSF
rhinorrhea is extremely rare: the fistula is usually found in the roof of the ethmoid sinus, less often in the walls of the sphenoid sinus. There is a striking prevalence of female patients. We describe a female patient who showed spontaneous
CSF
rhinorrhea from a leak in the anterior roof of the sphenoid sinus. The possible aetiology, diagnostic measures and therapy are discussed. Areas of reduced resistance in the anterior skull base may be congenital, or may be acquired due to later focal atrophy. The diagnosis of
CSF
rhinorrhea can be established by the glucose test, isotope scanning, immunoelectrophoresis and fluorescence endoscopy. The most reliable methods of distinguishing between a traumatic or neoplastic lesion and a spontaneous
CSF
rhinorrhea are high-resolution computed tomography (CT) and magnetic resonance tomography. High-resolution CT is also the best method for localization of the bony defect. Elevated intracranial pressure must be ruled out carefully. The treatment of choice is closure of the fistula, preferably by the nasal surgeon, using either the endonasal-transseptal, the endonasal-transethmoidal or the paranasal-transethmoidal approach in order to preserve olfaction and to avoid the risk of a frontal lobe lesion which is a complication of the neurosurgical approach. Interposition of a fascial or dural graft is considered to be an important technical detail for achieving a secure closure of the fistula; packing can be avoided by additional sealing of the patch with fibrinogen glue.

In 1987, four children between 5 and 13 years of age with severe frontobasal trauma and dural tears were treated operatively. A
CSF
rhinorrhea was manifest clinically in only two cases. In addition high-resolution computerised tomography was essential in diagnosis and planning of the operation. In each of the cases an intracranial pneumatocele indicating dural laceration was shown. The fractures were confirmed during surgery in: Case 1. The roof of the ethmoid sinus and the roof of the orbit. Case 2. Both the sphenoid sinuses. Case 3. The roof of the ethmoid sinus and the posterior wall of the frontal sinus. Case 4. The roof of the ethmoidal sinus and the posterior wall of the frontal sinus. The ontogenetically oldest part of the paranasal sinuses in the floor of the anterior cranial fossa forming the anterior part of the roof of the ethmoid bone is the site of predilection for fractures, even in children. The anterior cranial fossa was exposed in each case through a paranasal subfrontal access, in the first case combined with a frontal craniotomy by a neurosurgeon, because of the fracture of the roof of the orbit. In the second case the dural injury had to be closed at a second neurosurgical operation, because of a recurrence of the
CSF
leak. The third and fourth cases were treated by nasal surgery alone.

Meningopolyradiculitis (Garin-Bujadoux syndrome, Bannwarth syndrome) is the second stage of Lyme disease, a tick-borne Borrelia infection. Almost 60% of these patients develop an acute peripheral facial paresis. The disease can be differentiated from Bell's palsy only by finding the specific Borrelia antibodies in serum and
CSF
. Other cranial nerve lesions can be found besides facial paresis. The follow-up of seven Borrelia-infected patients is described: one showed bilateral, the others unilateral, facial paresis. High dosage of penicillin or tetracycline for 10-14 days is the appropriate therapy. The prognosis of facial paresis in tick-borne Borrelia infection is considered to be good. All our patients showed complete recovery of motor nerve function.

Audiometric examination of children who have suffered a bacterial meningitis show that in about a quarter of them a moderate to severe, often unilateral, hearing loss is to be expected despite antibiotic treatment. Hearing loss is more frequent in cases of severe meningitis and appears to depend upon the time of treatment. The most feared infection is that due to Hemophilus influenzae. No hearing damage was encountered in meningitis due to virus, in confirmed mumps infection or when the
CSF
was free of bacteria.

For the past 25 years we have been able to control severe epistaxis in all patients by an intranasal procedure. If the source of bleeding in patients with epistaxis from the upper part of the nose cannot be seen during the acute phase, a combined anterior-posterior nasal pack is inserted and left in place for three days. Should bleeding persist or recur after removal of the packing we resect the superior nasal septum to expose the bleeding point in the anterior area of the cribriform plate. Cauterization at this site is not safe because of the risk of
CSF
rhinorrhea, and it is not always successful, as the main blood supply to the ethmoidal arteries stems from the internal carotid artery. Cauterization of the anterior or posterior ethmoidal arteries within the bony canal of the ethmoidal sinus (after partial ethmoidectomy) is always successful. Ligation or embolization of the carotid arteries is indicated only for tumour patients. Intranasal ethmoidal microsurgery requires much practice and preliminary experience on at least 50 cadavers. In 25 years with an annual load of about 180 ethmoidal sinus surgery cases we have never had serious complications such as cerebrospinal fluid rhinorrhea or persisting optical disturbances in more than 4,000 operations. During 1984 at the Krupp Hospital we used the intranasal microsurgical approach for all patients with septal, ethmoidal sinus and lacrimal duct pathology, for 98% of cases requiring maxillary sinus procedures and for 82% of patients with frontal sinus problems.(ABSTRACT TRUNCATED AT 250 WORDS)
