Sudden hearing loss in sarcoidosis: otoneurological study and neuroradiological correlates

Sarcoidosis is an inflammatory multisystem disorder of unknown cause. Approximately 5-7% of patients manifest symptoms of central nervous system involvement, or neurosarcoidosis. Cranial neuropathy usually entails facial nerve palsy and optic neuritis. Sudden hearing loss has been reported in fewer than 20 cases. Herewith, two new cases of sudden hearing loss due to probable neurosarcoidosis are reported, each having a quite different clinical course. In one case, unilateral sudden hearing loss and facial palsy were the presenting symptoms of systemic sarcoidosis, while in the second, unilateral sudden deafness occurred despite ongoing immunosuppressive treatment for systemic sarcoidosis.

Coiling and neuroendoscopy: a new perspective in the treatment of intraventricular haemorrhages due to bleeding aneurysms

BACKGROUND

Intraventricular haemorrhages (IVHs) caused by bleeding aneurysms are critical conditions that often carry a severe prognosis. Two main problems must be urgently dealt with: the secondary damage caused by intraventricular clotting and the risk of early rebleeding. A protocol of ultra-early endoscopic ventricular evacuation, after securing the aneurysm with coils, is proposed to solve this challenge in the acute phase and within a few hours of onset.

METHODS

Ten consecutive patients presenting with haematocephalus from aneurysm rupture were treated in our institute with coiling and endoscopic clot aspiration extended to the whole ventricular system. The only inclusion criteria were the presence of a massive IVH and an aneurysm appropriate for coiling. Computed tomography scans obtained before (within 4 h of symptom onset in all patients) and immediately after surgery were compared for Graeb score and ventriculocranial ratio (VCR); the Glasgow Outcome Scale (GOS) was assessed at 1 year.

RESULT

All patients were treated within 2 days of onset. The procedure resulted in a mean 58% removal of ventricular blood and decrease of hydrocephalus; the mean (standard deviation (SD)) Graeb score reduced from 11.5 (0.7) to 4.7 (2.2) (p<0.001) and mean ventriculocranial ratio from 0.26 (0.06) to 0.17 (0.05) (p<0.001). No rebleeding or delayed hydrocephalus needing shunt was observed. Mortality at 1 year was 30%; marked disability (GOS = 3) and good recovery (GOS = 5) were observed in 40% and 30% of patients, respectively.

CONCLUSIONS

Early neuroendoscopic removal of blood casting from the lateral to the fourth ventricle after coiling of bleeding aneurysms is a feasible approach, allowing in most instances the rapid improvement of the IVH.

Upper airway obstruction by retropharyngeal hematoma after cervical spine trauma: report of a case treated with percutaneous dilational tracheostomy

The authors report the case of a patient affected by a cervical spine trauma who developed upper airway obstruction as a result of a retropharyngeal hematoma. An endotracheal intubation with a small-diameter tube was performed, but ventilation and oxygenation were not adequate. An early Percutaneous Dilational Tracheostomy with the Ciaglia technique was then performed. The risk of upper airway obstruction by retropharyngeal hematoma after cervical spine trauma is discussed in this article, as are the feasibility and benefits of using Percutaneous Dilational Tracheostomy in emergency cases of upper airway obstruction.

Adjustable silicone gastric banding for obesity

Adjustable gastric banding is the least invasive operation for morbid obesity. Forty-eight patients underwent surgical adjustable gastric banding between March 1990 and August 1991. In 15 of these patients, radiological examination was performed in the early postoperative period because of dysphagia and vomiting, revealing stenosis of the stoma in all cases (caliber less than 0.3 cm); in all patients we easily punched, with fluoroscopically guided observation, the inflatable portion and obtained a true calibration of the gastric banding. In seven patients radiological examination was performed 2 months after surgical treatment because of a lack of weight loss. Radiological findings explain surgical failure, revealing a too wide stoma in four patients, the absence of a gastric pouch due to a too high position of the band in two, and the caudal sliding of the banding in one patient.

[Functional evaluation of the anorectal region]

Defecography is a method allowing the morphodynamic evaluation of the anorectal region. The technique we employed needs two complementary times: "phase" defecography and dynamic defecography. In our series of patients affected with severe constipation, 2 groups could be identified. Group A included those patients (mean age: 38.7 years) in whom no significant changes were observed in anorectal angle and in the distance of anorectal angle from pubococcygeal line in comparison with normal subjects (Student's t-test). Group B included those patients (mean age: 63.3 years) in whom significant reduction was observed in anorectal angle on straining, together with increased distance of anorectal angle from pubococcygeal line on squeezing in comparison with normal subjects (Student's t-test). In constipated patients narrowed anal canal was observed (60%), together with rectocele (42.6%), mucosal prolapse (27.8%), rectal prolapse (18%) and solitary ulcer (14.7%). In idiopathic incontinence patients (mean age: 63.3 years), increased distance was observed of anorectal angle from pubococcygeal line on squeezing and, in the most severe cases, even at rest, with the patient sitting (Student's t-test). In incontinent patients larger anal canal was observed (67.6%), together with rectocele (36.7%), mucosal prolapse (14.7%), and rectal prolapse (11.7%).
