Introduction: The development of recommendations for the treatment of rheumatoid arthritis (RA) in the Cuban context may be one of the ways to achieve better control of this disease. Objective: To reach a consensus and update relevant aspects of conventional and biological RA modifier therapy in Cuba. Methods: 18 specialists from 8 Cuban provinces, experts in RA care, were summoned, according to the years of dedication to the specialty, the conferences on this topic and their publications. The first meeting took place in March 2016 in the provincial hospital of Villa Clara, Cuba, with the participation of all the experts. A review of the literature on conventional and biological therapy previously collected by the participants was developed, and two teams were formed: the first would address everything related to conventional therapy in RA (HRCT) and the other, biological therapy in RA (TBAR). Three questionnaires related to the use of corticosteroids, HRCT and TBAR, were prepared, answered by the participants via email. In a second meeting, held in October 2016 in Havana, the analysis of all the responses provided was carried out. Questions with a response of 90% or more votes were considered as recommendations. Results: The questionnaires were answered by 95% of the participants. 9 recommendations and 1 algorithm were established. The recommendations are as follows: methotrexate is the drug of choice in the treatment of RA after diagnosis; The administration of another conventional drug (DMARDc) (azathioprine, salazosulfapyridine, antimalarials and leflunomide) is recommended in patients with a diagnosis of active RA in whom methotrexate is contraindicated or there is a failure in response - consider the administration of low doses of prednisone or equivalent (<7.5 mg/d) associated with DMARDc in patients with active moderate to severe RA, for the shortest possible time; perform serological control including tests for hepatitis B and C viruses and screening for HIV in all patients diagnosed with RA before starting treatment with DMARDc and biologics; in patients in remission or, at least, with a DAS-28 below 3.2, consideration should be given to withdrawing one of the DMARDs or reducing, to the minimum possible expression, the dose of both disease modifiers; if methotrexate fails, tocilizumab in combination with methotrexate or as monotherapy will be indicated. Conclusions: Aspects related to conventional therapy with methotrexate, azathioprine, salazosulfapyridine, antimalarials and leflunomide were agreed. The value of early diagnosis and immediate initiation of DMARDc therapy and the use of glucocorticoids was analyzed. Treatment with tocilizumab, the only biological available in Cuba against RA, will be administered when there is a failure in the response to conventional therapy and combinations between these drugs. It is recommended to hold educational conferences through the mass media aimed at patientshttp(AU)

Tenosynovitis is the inflammation of the tendon and synovial sheath. It is commonly affects hands and wrist. The etiology may be infectious or inflammatory. In patients with Systemic Lupus Erythematosus (SLE) the periarticular and tendinous commitment is frequent. Intra-articular corticosteroids (CO) are effective as adjuvant of the systemic therapy. Complications of use are infrequent. The case of a female patient is presented, 32 years old, with SLE and chronic renal failure secondary to lupus nephritis, chronic user of oral CO. She is infiltrates with intra-articular deposit betamethasone in metacarpal-phalangeal (MCP), because of articular edema. Twelve days later evolves with Compartment Syndrome (SC). Fasciotomy show findings compatible with chemical synovitis by betamethasone crystals. Currently there are quite few reports in the literature of CS with presentation in fingers. The diagnosis is mainly clinical. The common use of intra-articular CO is not without risk and should be planned and diagnosed early...
Tenosinovitis es la inflamación del tendón y vaina sinovial. Es más frecuente en manos y muñecas. Su etiología es infecciosa o inflamatoria. En pacientes con Lupus Eritematoso Sistémico (LES) el compromiso periarticular y tendíneo es frecuente. Los corticoides (CO) intraarticulares son efectivos como adyuvante de terapia sistémica. Las complicaciones de su uso son infrecuentes. Se presenta el caso de paciente sexo femenino, 32 años, con LES e insuficiencia renal crónica secundaria a nefropatía lúpica, usuaria de CO orales. Por edema articular se le infiltra betametasona de depósito intraarticular en metacarpo-falángica (MCF). Evoluciona doce días después con Síndrome Compartimental (SC). Durante la fasciotomía se evidencian hallazgos compatibles con sinovitis química por cristales de betametasona. Existe escaso reporte en la literatura de SC en dedos de la mano. El diagnóstico es principalmente clínico. El uso común de CO intraarticulares no está exento de riesgos y deben ser previstos y diagnosticados precozmente...

The discovery and first dates of the paintings in Grotte Chauvet provoked a new debate on the origin and characteristics of the first figurative Palaeolithic art. Since then, other art ensembles in France and Italy (Aldène, Fumane, Arcy-sur-Cure and Castanet) have enlarged our knowledge of graphic activity in the early Upper Palaeolithic. This paper presents a chronological assessment of the Palaeolithic parietal ensemble in Altxerri B (northern Spain). When the study began in 2011, one of our main objectives was to determine the age of this pictorial phase in the cave. Archaeological, geological and stylistic evidence, together with radiometric dates, suggest an Aurignacian chronology for this art. The ensemble in Altxerri B can therefore be added to the small but growing number of sites dated in this period, corroborating the hypothesis of more complex and varied figurative art than had been supposed in the early Upper Palaeolithic.

Heteropropic ossification was initially described by Riedel in 1883. This is a rare disease but well documented in gastrointestinal tract. Several mechanisms have been proposed to determine the etiology of this metaplasia. We present a 59 year old male that was treated in the National Institute of Medicine Sciences and Nutrition Salvador Zubirán in whom after various abdominal surgical procedures the presence of bowel osseous metaplasia was documented.

Cortisol concentrations were determined during the perinatal and weaning periods in alpacas. Fifty males and 50 females were chosen at random (25 at each period) for blood collection on day of parturition, 3 and 5 days after birth. For the weaning period, blood samples were collected 2 days before, on the day of weaning (0), and at days 3 and 5 after weaning. Cortisol was determined using an ELISA protocol validated for the alpaca. There was no difference (P>0.05) in cortisol concentrations in both periods, perinatal and weaning between male and female crias. Cortisol was elevated at day of parturition (125.8 ng/ml) and then decreased to 27.2 ng/ml at 3 days after birth (P<0.05). Conversely, cortisol was 32.5 ng/ml 2 days before weaning and then increased at day 3 to 64.7 ng/ml (P<0.05), but then decreased to 29.4 ng/ml at day 5 after weaning. Cortisol is elevated in new-born alpacas and then decreases at the third and fifth after birth. Concentrations of cortisol are also increased after weaning and then decreased 5 days after weaning.

OBJECTIVES: We assessed recent (1992-1997) HIV incidence in the large HIV epidemic among injection drug users in New York City. METHODS: Data were compiled from 10 separate studies (N = 4979), including 6 cohort studies, 2 "repeat service user" studies, and 2 analyses of voluntary HIV testing and counseling services within drug treatment programs. RESULTS: In the 10 studies, 52 seroconversions were found in 6344 person-years at risk. The observed incidence rates among the 10 studies were all within a narrow range, from 0 per 100 person-years at risk to 2.96 per 100 person-years at risk. In 9 of the 10 studies, the observed incidence rate was less than 2 per 100 person-years at risk. The weighted average incidence rate was 0.7 per 100 person-years at risk. CONCLUSIONS: The recent incidence rate in New York City is quite low for a high-seroprevalence population of injection drug users. The very large HIV epidemic among injection drug users in New York City appears to have entered a "declining phase," characterized by low incidence and declining prevalence. The data suggest that very large high-seroprevalence HIV epidemics may be "reversed."

Carcinoma of the uterine cervix is the most frequent malignancy in women in developing countries. Based on the possible synergistic effect of the combination of interferon and radiotherapy, a clinical trial was conducted in patients with advanced cervical cancer. The objective was to evaluate the efficacy and security of such a therapeutic approach. This prospective phase II trial was done at the Instituto Nacional de Cancerología in Mexico City. The study included 17 consecutive patients with previously untreated squamous cell cervical cancer, clinical stages III and IV, and tumor mean size of 9.7 cm. The patients received radiotherapy and interferon alpha-2b at a dose of 5 x 106 IU/m2 3 times a week for 6 weeks. Eleven (64%) complete responses were obtained among these patients. Long-term survival was observed in 4 patients (24%) who achieved complete response and are alive after 10 years of follow-up. Immediate toxicity was mild. Late toxicity included the development of proctitis in 13 patients, colostomy was performed in 3 (23%) of them. Our results indicate that the combination of radiotherapy and this cytokine is an active therapy for squamous cell carcinoma of the uterine cervix.
RESUMO
Here we report the sequence of 569,202 base pairs of Saccharomyces cerevisiae chromosome V. Analysis of the sequence revealed a centromere, two telomeres and 271 open reading frames (ORFs) plus 13 tRNAs and four small nuclear RNAs. There are two Tyl transposable elements, each of which contains an ORF (included in the count of 271). Of the ORFs, 78 (29%) are new, 81 (30%) have potential homologues in the public databases, and 112 (41%) are previously characterized yeast genes.
