Spontaneous CSF fistula as a manifestation of idiopathic intracranial hypertension

INTRODUCTION

Spontaneous cerebrospinal fluid (CSF) fistula, of unknown origin, is a rare condition whose aetiology is increasingly related to idiopathic intracranial hypertension (IIH). This study tries to raise awareness that they should not be considered as two different processes, but that fistulas can be a form of debut, requiring a study and subsequent treatment. Repair techniques are described, as well as the study of HII.

RESULTS

We treated 8 patients, 5 women and three men, aged between 46 and 72 years, with a diagnosis of spontaneous CSF fistula, four nasal and four otics who underwent surgical treatment. After repair, a diagnostic study was performed for IIH by MRI and Angio-MRI, presenting in all cases a transverse venous sinus stenosis. The intracranial pressure values obtained by lumbar puncture showed values of 20mm Hg or higher. All patients were diagnosed with HII. The one-year follow-up did not reveal any recurrence of the fistulas, maintaining a control of the HII.

CONCLUSION

Despite their low frequency of both cranial CSF fistula and IIH, an association of both conditions should be considered by continuing the study and surveillance of these patients after fistula closure.

[Diagnosis and Treatment in frontobasal fractures]

Traumatic brain injury can result in frontobasal fractures (FBF). The goals of treatment for FBF are to eliminate primary morbidity and/or prevent secondary morbidity. Of particular importance in this regard is the proximity of important sensory organs for hearing, vision, smell, and taste, as well as their supplying nervous structures. Medical history, clinical findings, or CT scan are necessary and should lead to an individual evaluation. Depending on the severity of the fractures, the following disciplines may be involved in the treatment of FBF: neurosurgery, plastic surgery, oral and maxillofacial surgery, and/or otorhinolaryngology. Particularly less invasive endoscopic endonasal therapy is a specialty of otorhinolaryngologic surgeons and has not been widely established in other disciplines. The present work provides an overview of the current state of the art in terms of the following aspects, taking into account the current literature: anatomic principles, classification of fractures, diagnostics (in particular clinical examination, imaging, and laboratory chemistry tests), clinical symptoms, and treatment.

Improvement of Pulmonary Function in Arthrogryposis Multiplex Congenita Patients Undergoing Posterior Spinal Fusion Surgery for Concomitant Scoliosis: A Minimum of 3-Year Follow-up

OBJECTIVE

We sought to investigate the long-term outcome of pulmonary function for arthrogryposis multiplex congenita (AMC) patients undergoing posterior spinal fusion (PSF) and to further determine influential factors.

METHODS

Eighteen AMC patients with a minimum of 3-year follow-up after PSF were prospectively collected. All the patients underwent a pulmonary function test before surgery and at the final follow-up. The percentage predicted values of vital capacity (VC%) and forced vital capacity (FVC%) were recorded. The following radiographic parameters were collected including Cobb angle and thoracic kyphosis. The total lung volumes (TLV) were measured on the image of 3-dimensional computed tomography scan by the reconstruction software.

RESULTS

There were 10 males and 8 females with a mean age of 13.8 ± 6.1 years. The mean preoperative VC% and FVC% were 40.5% ± 7.6% and 39.5% ± 4.7%, which were significantly increased to 52.0% ± 7.5% and 51.2% ± 6.8% at the final follow-up (P < 0.001). Besides, there was remarkable improvement in terms of TLV (1.57 ± 0.2 L vs. 2.39 ± 0.6 L, P < 0.001). Remarkable correlations were observed between TLV and pulmonary function tests (r = 0.79, P < 0.001 for VC%; r = 0.78, P < 0.001 for FVC%). Multiple regression analysis showed that 2 variables including Δ thoracic kyphosis and Δ Cobb angle were independently associated with the improvement of pulmonary function.

CONCLUSIONS

The pulmonary function of AMC patients can be well improved through PSF surgery. It was remarkably associated with the correction of curve magnitude and restoration of thoracic kyphosis.

[CME: Rare Clinical Presentation of Bacterial Meningitis]

CME: Rare Clinical Presentation of Bacterial Meningitis Abstract. We report the case of a 59-year-old woman presenting with watery rhinorrhea and light cough for the last three days and new onset of a headache. The evaluation proved a bacterial meningitis. We started an inpatient therapy according to the established guidelines. Due to recurrent vigilance reduction and increasing rhinorrhea we performed a liquid analysis with beta-trace testing which revealed a rhinoliquorrhea. Through an exploration of the skull base liquor leaks were detected and sufficiently closed.

Unusual Position and Presentation of Frontobasal Meningoencephalocela

We wish to show our experiance with threating a rare congenital brain malformation-encephalocele. It is a protusion of brain matter with greater incidence in the Far East. Our case is even more curious because of the site of occurrence-frontobasal. Most of encephalocele occur in the occipital region. In this article we report a case of a 57-year-old woman, without deformations on the face, which had epileptic seizures and in spite of receiving antiepileptic drug. She was also frequently treated for sinusitis. She never had rhinoliquorrhea, nor was she diagnosed to have meningitis. In the last few years she had difficulty breathing on her right nostril. After she was diagnosed with encephalocele and treated surgically her recovery was complete and she is without the seizures.
