[Assessment of drug treatment for hypertension in a health centre as a function of associated chronic pathologies and degree of control of the hypertension].

OBJECTIVE: To assess the suitability of whatever hypertension medication is prescribed for the associated pathology in each patient, and to analyse the monitoring of blood pressure figures. DESIGN: A cross-sectional descriptive study.Setting. Urban health centre. PATIENTS: The target population were the hypertension patients being treated with medication and monitored at the health centre. Stratified random sampling by quotas of the total number with hypertension was performed. The sample numbered 219 patients. MEASUREMENTS: The clinical history of each patient selected was reviewed. To evaluate the hypertension treatment, we established three levels of suitability with regard to the accompanying pathology of each patient (suitable, intermediate, unsuitable), using the 1999 Hypertension Protocol of the Spanish Society of Family and Community Medicine. RESULTS: Out of 219 cases, treatment was suitable in 71 (32.4%), intermediate in 91 (41.6%), and unsuitable in 57 (26%). The most frequently indicated drug group was the angiotensin converting enzyme inhibitor (ACEI) group and, jointly, ACEI and diuretics. Regarding the monitoring of blood pressure: 66.5% had very good monitoring, 23.2% partial and 9% poor. CONCLUSIONS: Most treatments are at an intermediate level of suitability: without beneficial or undesirable effects on the associated pathology. This makes us think we need to optimize the drug indicators for hypertension.

[Diagnostic evaluation of nasopharyngeal carcinoma: role of Epstein-Barr virus].

We present a retrospective series of 27 nasopharyngeal carcinomas, selected from those attended at Ramón y Cajal Hospital between 1977 and 1996, with the aim of review the role of the study of Epstein-Barr virus in the diagnostic process of nasopharyngeal carcinoma. Twenty-seven patients, ranging from 14 to 81 years, with an average age of 50 years were selected. Male/female ratio was 1,7. All but one case were Caucasian. A neck mass was the first symptom in 40% of cases, with a mean diagnostic delay of 17 months. Only 8 cases (23%) did not exhibit neck nodes at the moment of diagnosis. CT and MRI were essential to establish staging: 5 stage I, 7 stage II and 15 stage IV, due to regional extension and/or bone erosion. Radiotherapy was employed in all cases, helped by chemotherapy in 20% of them. With a mean follow-up of 62 months, 5-years survival was 32% (IC 14,06-52,09). Of 27 cases of nasopharyngeal carcinoma 4 were differentiated (type I), 2 moderately differentiated (type II) and 22 undifferentiated (type III). While LMP-1 was only expressed by 41% of cases, PCR detected Epstein-Barr virus genome in 26 cases (96%) and in situ hybridization for EBERs was positive in all cases. Thus, all nasopharyngeal carcinomas were related to Epstein-Barr virus. Expression of LMP-1 seemed to worse the prognosis of nasopharyngeal carcinoma.

[Parapharyngeal abscess: perilaryngeal infrahyoid extension].

Parapharyngeal abscesses are located between the skull base and the hyoid bone. Their infrahyoid extension is usually following the retropharyngeal space, but also can be through the medial aspect of the parapharyngeal space. Thus, surrounding the visceral fascia, they might invade the perilaryngeal and perihypopharyngeal spaces. This results in more significant airway compromise. Computed tomography is essential while locating and evaluating the extension of these infections, specially with regards to the great vessels. We report on 8 parapharyngeal abscesses with perilaryngeal and/or perihypopharyngeal extension. We review their clinical and radiological features, based on computed tomography, as well as their medical and surgical treatment. When medical therapy fails, as they are usually medial to the great vessels, it is possible to perform aspiration and drainage transorally, avoiding the need for cervicotomy, in selected cases.

[Post-tracheotomy pneumothorax. Is thoracic radiography required after each tracheotomy?].

Pneumothorax complicating a tracheotomy is a rare event, but it should be clinically considered in order to the early treatment, mostly in urgent or pediatric cases. We report 2 cases in which pneumothorax complicated postoperatively the tracheotomy and required early clinic and radiologic diagnosis followed by a promptly and satisfactorily evacuated. We review the need to perform a chest X-Ray after every tracheotomy or only following those cases found to be at risk, as well some effective preventive measures.

[Congenital anomalies of the first branchial cleft. Retrospective study].

Anomalies of the first branchial cleft are occasional problems putting up diagnostic and therapeutic difficulties, because the imperfect settlement of reminders of this cleft, which can appear as cysts or branchial fistula, among patients of any age. Though there are several recommended classifications in order to achieve a precious diagnosis and a total surgical removal, sometimes is laborious to correlate the clinical and the histological findings. We report a sequence of congenital periauricular anomalies operated in our Department during a ten-years-term and compare our findings of those quoted after the literature series.

[Thyroglossal cyst: retrospective study of 58 cases. Results of the Sistrunk operation].

Cysts of the thyroglossal duct are one of the most common causes of benign neck masses. They generally occur in young patients and are caused by a defect in thyroglossal duct closure, which sometimes is in close contact with the hyoid. Often several tracts are present. The most effective surgical procedure was originally described by Sistrunk in 1920 and modified in 1928. This technique is based on the removal of the central portion of the hyoid bone. This procedure has successfully reduced the number of recurrences compared to local excision of the cyst. A retrospective review was made of 58 cases to evaluate surgical results, especially recurrence rate, in relation to the resection or preservation of the hyoid bone. Results were compared with published series.

[Mucoepidermoid carcinoma of the larynx].

We report a case of poorly differentiated mucoepidermoid carcinoma of the larynx. The tumor was supraglottic, located on the left aryepiglottic fold, and produced left laryngeal paresis. The patient underwent total laryngectomy, functional neck dissection, and complementary radiotherapy. After 20 months, untreatable lung metastases appeared. Mucoepidermoid carcinomas of the larynx are rare. They are generally unresponsive to radiotherapy and are best treated surgically, although postoperative radiotherapy is advocated for high-grade, poorly differentiated cases.

[Nasal encephalocele: differential diagnosis with nasal glioma].

Congenital nose neoplasms are infrequent, between them neurogenic tumors of the middle line include nasal gliomata (glial ectopies) and nasal encephaloceles, according to an existing or lacking communicating link with the intracranial cavity. We report one congenital naso-encephalocele case in a 16-year-old girl suffering from repeated meningitis events after several nasal polypectomies performed in other departments. She underwent complete removal through fronto-neurosurgical and paralateronasal approach, being the young woman asymptomatic for 3 years. We discuss about both intranasal gliomata and encephaloceles, certainly of not easy pathologic identification, stressing the decisive value of imaging techniques, as magnetic resonance, in order to clearcut both the diagnosis and the therapeutical planning.

[Laryngeal tuberculosis and laryngeal cancer].

Account of 2 synchronic cases of tuberculosis and laryngeal carcinoma. Apart from bacteriostatic drugs one of them underwent a cordectomy the other one a total laryngectomy and neck dissection. Despite the great majority of laryngeal cancer it is compulsory to take in account the differential diagnosis with the tuberculosis, because of its possible coexistence. Perusal of national and international literature, having found only 11 of similar instances reported.

[The Protomedicato Tribunal and the royal physicians (1665-1724)].

This article tries to reconstruct the composition of the Board of Royal Physicians during the reign of Charles II (1665-1799) and the first part of the reign of Philip V (1700-1724), a crucial period in the introduction of modern science and medicine in the Spanish Kingdoms. Their personal records, to be found in the Archivo General de Palacio in Madrid, have been exhaustively consulted. Some of these royal physicians formed part of the Castilian Tribunal del Protomedicato, by means of which the Board of Royal Physicians was selected, promoted and controlled. The Protomedicato was an important battlefield in the conflict between traditional and modern medicine, in which Italian physicians played a decisive role.

[In tenebris adhuc versantes. the response of Spanish novatores to the invective by Pierre Régis].

Pierre Régis, a French Calvinist physician exiled in Holland, made a disparaging mention to the Spaniards and the Portuguese in his foreword to M. Malpighi's Opera Posthuma (Amsterdam, 1698). Several Spanish physicians, especially Diego Mateo Zapata, replied to Régis's invective in an attempt to win support from the new Borbonic dynasty for the scientific renovation movement started in the last decades of the seventeenth century. Two major institutions were involved in the replies: the Royal Society of Medicine and other sciences of Seville, and the Anatomical Theatre of the General Hospital of Madrid, both created during the reign of Charles II of Austria. The self-perception of the Spanish medical novatores and their awareness of the backwardness of Spanish science with regard to Europe are analyzed.
