[Langerhans cell histiocytosis of the temporal bone].

Eosinophilic granuloma (EG) is a localized, benign form of Langerhans' cell histiocytosis. It is the least severe of the histiocytosis syndromes and characterized by lytic lesions of one or more bones. Temporal bone lesions usually occur in association with multifocal disease, but isolated lesions may occur in either the mastoid bone alone or in the entire temporal bone affecting other sites in the body. Two cases of EG of the temporal bone are reported and the literature is reviewed.

[Secondary brain herniation. A case report].

A 47-year-old woman with left temporal bone herniation had a history of treatment of chronic cholesteatomatous otitis media. After clinical and radiological diagnosis, the defect was repaired using a middle fossa craniotomy approach and a Vicryl-collagen(R) plate. There were no postoperative surgical complications and the repair was successful. The sequellae of herniation of the temporal lobe and dura are potentially lethal and difficult to correct surgically.

Vitamin D metabolite-mediated hypercalcemia in Wegener's granulomatosis.

Hypercalcemia may occur during the course of various granuloma-forming diseases. Herein we describe a patient who had symptomatic hypercalcemia as a prominent sign of Wegener's granulomatosis. We observed a direct correlation between the serum levels of 1,25-dihydroxyvitamin D [1,25(OH)2D] and both the serum and the urinary calcium levels. Administration of prednisone and cyclophosphamide led to a substantial decrease in the levels of calcium and serum 1,25(OH)2D, but the serum levels of 25-hydroxyvitamin D remained unchanged. Two months after admission of the patient, the levels of calcium and 1,25(OH)2D increased; after we increased the dose of cyclophosphamide, these levels decreased (the dose of corticosteroids was not changed). We suggest that the excessive synthesis of 1,25(OH)2D was inhibited by a direct or indirect action not only of prednisone but also of cyclophosphamide on the 1 alpha-hydroxylation of 25-hydroxyvitamin D in the activated macrophage of Wegener granulomas. Furthermore, in view of this case and two other recently reported cases, we believe that Wegener's granulomatosis must be definitively added to the list of granulomatous diseases that are responsible for 1,25(OH)2D-mediated hypercalcemia.

[Obstructive apnea syndrome during sleep secondary to a pharyngeal lymphoma. Improvement with continuous pressure treatment of the upper airway].

Obstructive sleep apnea syndrome (OSAS) is characterized by multiple episodes of upper airway (UA) obstruction during sleep. Patients experience daytime hypersomnia, sluggishness and inability to concentrate; snoring at night is common. We report the case of a man with Hodgkin's lymphoma without full remission and with pharyngeal recidivism leading to OSAS. He experienced marked diurnal hypersomnia accompanied by behavior disorders. Examination revealed flow-volume OSAS, suggesting UA instability. Cervical computed tomography showed a prevertebral lymphomatous mass in the pharynx causing significant UA compression. UA size increased considerably after use of continuous positive airway pressure (CPAP), which normalized sleep and produced significant relief of symptoms. Later, after chemotherapy, OSAS resolved and the patient was able to abandon CPAP treatment.

[Yag-laser for the treatment of laryngeal and oral hemangiomas].

Laryngeal and bucal hemangiomas are uncommon, although they carry with them, because of its sitting, a vital risk. The AA. report 2 hemangioma cases, one localized on the edge of the tongue, the other one on the aryepiglottic fold. Both were treated with photocoagulation by neodymiun-yttrium-aluminium (Nd-YaG) laser, with favorable follow-up and few complications.

[Anatomical alterations of the upper airway in the sleeping apnea syndrome. Diagnostical and therapeutic implications].

In this paper are assessed through ENT-exam, rhinomanometry and cephalometry both bipedal and in dorsal decubitus, the anatomical alterations occurring in the upper airways in 100 consecutive patients, polysomnographically diagnosed of SAOS. The patients were classified in 4 groups (after Fujita's modified classification): 2 having oropharyngeal obstruction (I and IIa) and other 2 with hypopharyngeal obstruction (IIb and III), which were subdivided in its time with nasal obstruction present (N+) or absent (N-). Group I and IIa (68 %) -theoretical candidates to an uvulopalatopharyngoplasty, UPPP-showed its predominance, followed by a high incidence of nasal obstruction (N+, 48 %) and a non negligeable number of hypopharyngeal alterations (32 %).

[Evaluation of the cephalometric structure of the upper airway on the configuration of the obstructive sleep apnea syndrome].

Thirty aleatory patients polysomnographically diagnosed as sleep apnea syndrome (SAOS) with an apnea-hypoapnea index (AHI) accounting for 61.3 +/- 31.1 were, bipedal and in decubitus, cephalometrically explored, aiming at establish the correlation between the cephalometric quantum of the upper airway and the anthropomorphic and polysomnographic parameters clearly establishing the syndrome. The weak correlation confirmed among the AHI and the back passage in decubitus (PASDEC), even between the nocturnal oxymetric nadir and the length of the palate, advice against considering the gravity of the OSAS as sole function of the altered cephalometric degree checked in the test.

[The incidence of the inappropriate ADH secretion syndrome (SIADH) in major otorhinolaryngologic surgery].

There are few works dealing with the presentation of the inadequate secretion of antidiuretic hormone in major ENT procedures. In this prospective study done by the AA., based in analytic data, they found out the presence of the syndrome in as many as 39 percent of those operations. Consequently the suggestion is made that major ENT-surgery must be considered among the potential factors of the syndrome.

[Thornwaldt's cyst. The experience of a decade].

The cyst of the Thornwaldt's bursa is a bulge on the postero-superior wall of the rhinopharynx, due to the closure of the sac's drainage duct. The bursa pharyngea being an embryologic remnant occurring in 3 percent of healthy adults. It is a process well known since a century, but only 11 cases (in 9 several publications) have been quoted in the last 20 years. Perusal of the cases seen at the ENT Department of the Clinic and Provincial Hospital of Barcelona during the latter decade.

[Otological assessment in patients operated on for cleft palate].

Tympanometry and otoscopy has been carried out to determine the presence of middle ear disease on patients with cleft palate and the influence of corrective surgery. This explorations have been evaluated preoperatively and at one and six months postoperative follow-up. There is a high incidence of otitis media with effusion in patients with cleft palate, almost 60 per 100 in our study. The influence of cleft palate surgery repair has not revealed as a mayor factor on its resolution, although a visible benefit has been observed in the long term controls. We recommend a otorhinolaryngological follow-up in these patients.

[Cerebral abscess of otogenic origin located simultaneously in the temporal and cerebellar regions].

A 28-year-old male was seen for chronic left ear disease. A brain abscess appeared in the left temporal lobe and later spread to the cerebellum. Diagnosis was clinical and radiological. Intravenous antibiotic treatment resulted in resolution of the temporal abscess on CT. However, a new abscess that appeared in the left cerebellar hemisphere required neurosurgical debridement. The patient's microbiological cultures and history suggested an otological origin. Brain abscess is a serious complication of ear disease that requires early diagnosis and treatment.
