[Multiple genetic typing (vitamin D receptors and estrogens) in the assessment of the risk of fractures].

BACKGROUND: Several studies suggested that some vitamin D receptor (VDR) and estrogen receptor (ER) polymorphisms influence bone mass. However, others did not confirm these results. This study was undertaken to determine if the genotypes revealed by the combined analysis of VDR and ER polymorphisms are associated with clinically significant differences in peak bone mass and the risk of osteoporotic fractures. PATIENTS AND METHODS: Restriction fragment length polymorphisms of VDR were determined with the enzymes Bsml, Apal, Taql, and Fokl. Enzymes Xbal and Pvull were used as polymorphic markers of the ER. The study group comprised 149 young control women (18-34 years), 66 postmenopausal controls, 99 women with hip fracture and 76 women with osteoporotic vertebral fractures. Bone mineral density (BMD) was measured by DEXA. RESULTS: We did not find significant differences in lumbar spine or hip BMD among young women with different genotypes (determined with either single or multiple polymorphic markers). Likewise, there were no differences in the frequency distributions of VDR or ER alleles between control and fractured women. The study had a 77% power to detect a fracture odds ratio of 2 in case of genotypes present in at least 15% of the population. CONCLUSIONS: These results suggest that the polymorphic markers used in this study do not have enough discriminant power to be clinically useful in the assessment of fracture risk.

[Pulmonary epidermoid carcinoma in a 22-year-old patient with multiple cutaneous metastasis].

The authors present one clinical case of lung epidermoid carcinoma with several concurrent features which are uncommon in relation to this type of neoplasia. Consequently, the age of the patient (22), the lack of known risk factors, the histologic type (little differentiated squamous) and an aggressive biologic behaviour of the tumour, preceded of multiple cutaneous metastasis, are circumstances that make this clinical case exceptional. The more significative aspects present at lung carcinoma included in this age group respect to others are analyzed.

[Relapsing polychondritis with atypical presentation].

Relapsing polychondritis is an episodic systemic disorder, characterized by recurrent inflammation that affects cartilaginous structures, the cardiovascular system, eyes and ears. Although the etiology is unknown, experimental evidence strongly suggest that immunologically mediated mechanisms are implicated. Auricular, articular and nasal manifestations are the most frequent disturbances. In about 30% of cases, relapsing polychondritis is associated with other connective tissue diseases and vasculitis. Actually, the diagnosis is based on the criteria proposed by McAdam, and modified by Damiani. We present a case, whose first manifestations of relapsing polychondritis were an intermittent fever and transient arthralgias. Eight months later, auricular chondritis appeared, and gave us the key to diagnosis.

[Peritoneal pseudomyxoma secondary to mucinous cystadenoma of the ovary].

We present a new case of pseudomyxoma peritonei secondary to a mucinous cystadenoma of the ovary, whose presenting symptoms were abdominal distension and bilateral hernias. This is an uncommon entity and diagnosis tends to be casual. Each day, ultrasonography and computed tomography are more useful in suspicion. Aggressive surgical debulking followed by intraperitoneal chemotherapy seem to be the better treatment, even though controversies persist.

[Varicella pneumonia in the adult].

In the adult, the primary infection by the varicella-zoster virus acquires an unusual severity due to several complications, the most frequent of them being pneumonia. The authors analyze the clinical, epidemiological, serological and radiological data of the only two cases of varicellous pneumonia in the adult at a general hospital during the past 5 years. They highlight as the main characteristics: easiness of diagnosis, dissociation between clinical and radiological signs and the excellent therapeutical response to the early administration of intravenous Aciclovir. They comment as well the risk factors of this complication and the criteria for hospitalization.

[Yersiniosis in a general hospital in the Basque country (1984-1989). Clinical and epidemiological aspects].

BACKGROUND: The features of the diseases caused by Yersinia have not been properly evaluated in the Basque Country. The present study was performed to assess the incidence and consequences of this infection. METHODS: 51 cases of Yersinia infection in a general hospital during the period 1984-1989 were reviewed. Clinical, epidemiological, microbiological, and therapeutic data and the hospital stay were evaluated. RESULTS: 62% of patients were males with a mean age of 16 +/- 19.4 years. Most came from urban areas. 40% of cases developed in winter and 32% in summer. The presenting features were: acute gastroenteritis (66%), pseudoappendicitis (10%), sepsis (4%), lymphadenopathy (2%) and others (18%). 40% of the patients had significant underlying diseases, and 16% had complications attributable to the infection. The microbiological diagnosis was made by stool culture in 88%. 96% corresponded to Yersinia enterocolitica (biotype 4), serogroup 0: 3 (93%). Yersinia pseudotuberculosis was isolated from the culture of a cervical lymph node in one patient. In the Yersinia enterocolitica strains the most common antibiotic resistances were to ampicillin (87%), cephalotin (81%), ticarcillin (75%), mezlocillin (43%) and piperacillin (43%). The mean hospital stay was 6.1 +/- 12.2 days and it was significantly shorter in children (3.3 +/- 6.1%) than in the adult population (10.9 +/- 17.4) (p less than 0.05). It was longer in patients with underlying diseases (13.3 +/- 17.8 vs 3.3 +/- 5.6) (p less than 0.005). CONCLUSIONS: Our patient population had male and urban predominance. Most infections were caused by Yersinia enterocolitica and presented as acute gastroenteritis, without differences between winter and summer. We point out to the relationship between Yersinia infection, abnormalities in iron metabolism and immunosuppression. There were few complications of the infection. The mean hospital stay was directly correlated with age and underlying diseases.
