ABSTRACT
The prevalence of antibodies against human T-cell lymphotrophic virus (HTLV-I/II) in blood donors from the city of Monterrey, Mexico was investigated. We found that 4 out of 1017 sera (0.39%) reacted against HTLV-I/II, as determined by a passive agglutination test (PA). However, none of PA-positive sera reacted to HTLV-I/II specific polypeptides as demonstrated by Western blot. These findings indicate that the population of Monterrey has very low or no seroprevalence for HTLV-I/II.

We report a case of a woman of Mexican origin with oculopharyngeal muscular dystrophy (OMD). This is the first OMD reported in Mexico. She was healthy until the age of 30, when she noticed slowly progressive ptosis and dysphagia. She developed dermatitis and polyneuritis which we attribute to a deficiency of nutrients due to her dysphagia. In contrast to most previous reported cases this patient had also a distal myopathy. It is recommended in this type of patients a strict dietary control in order to avoid complications. It is also recommended to perform biopsies of several muscles to complete the diagnosis and prognosis.

Se analizan siete casos de disgenesia gonadal pura. Este sindrome se caracterizo principalmente por amenorrea, hipergonadotropismo, utero hipoplasico, gonadas en estrias y foliculos ovaricos ausentes o atresicos. Cinco de las pacientes tenian amenorrea primaria y dos gemelas dicigoticas amenorrea secundaria. De las observaciones efectuadas, la falla ovarica inicial es la forma clasica de disgenesia gonadal y la falla ovarica prematura se considera como una variante de la digenesia gonadal. Este sindrome se manigesto acompanado de sordera, gemelaridad y sindrome de Bloom
