Teaching about chronicity in medical schools - A review of the current situation.

In recent decades, progressive population aging in developed countries has led to a significant increase in the number of people with at least one chronic medical condition. As a result, acquiring knowledge about chronicity in medical school is key for physicians to be able to provide proper management for these patients. However, the presence of chronicity in educational curricula is scarce and highly variable. On the one hand, this work consisted of a review of the educational programs of the main medical schools on each continent with the aim of identifying whether they included chronicity and, on the other, a literature review focused on identifying educational projects in the field of chronicity. The presence of chronicity in most medical schools' curricula is marginal and only a few universities include specific skills or competences linked to chronicity. In most cases, this topic appears as a global, cross-curricular competence that students are supposed to acquire over the course of their entire education. The literature review retrieved 21 articles on innovative teaching projects on chronicity. Direct contact with chronic patients, most times as "health mentors," the role of the student as a teacher, and continuous evaluation and feedback from all participants are the main characteristics of the projects analyzed. Some previously published experiences support the usefulness of innovative methodologies for better approaching this capital field in current medical practice. Despite the current situation in which chronic patients consume most healthcare resources, the presence of chronicity in medical schools is marginal. However, a literature review did identify some useful experiences for improving education on chronicity in medical schools. Medical schools should change their academic curricula and redirect them towards providing students all the necessary tools for improving their knowledge on chronicity.

[Efficacy and safety of ezetimibe in vascular risk units]. / Eficacia y seguridad de ezetimiba en unidades de riesgo vascular.

OBJECTIVES: This study was intended to assess the efficacy and safety of ezetimibe when taken alone or combined with statins in a specialized care setting and under standard clinical practice conditions. PATIENTS AND METHODS: A multicenter, retrospective study in patients with dyslipidemia seen in a specialized outpatient clinic and treated with ezetimibe for at least 12 weeks. Patients were divided into three groups: monotherapy, add-on ezetimibe, and initial coadministration. RESULTS: A total of 217 patients (mean age 59 years; 37% ≥65 years) were enrolled. Of these, 61% were women, 21% had type 2 diabetes and 20% had had a previous cardiovascular event so that the lipid lower drug treatment should satisfy the objectives of secondary prevention. Mean change in the monotherapy group (n = 92; mean 41 weeks) included: decrease of LDLc of 28% (P <.001). In the group where ezetimibe was added on to different ongoing statins (n = 94, mean 73 weeks), mean changes was as follows: LDLc -34%, significant change as compared to monotherapy (P < .001). In the group with initial coadministration of ezetimibe with different statins (n = 31; mean 118 weeks), mean change included: LDLc -53% (P < .001). Overall, 64% of patients reached the thereapeutic objective proposed for the Adult Treatment Panel III (ATPIII) for cLDL. In patients with low risk (LDLc < 160 mg/dL), moderate risk (LDLc < 130 mg/dL) and high-very high risk (LDLc < 100-70 mg/dL), the percentage of patients who reached the therapeutic objective was 81%, 64% and 44%, respectively. CONCLUSIONS: Under standard clinical practice conditions, ezetimibe appears to be effective and safe for the control LDLc, thus making it possible to reach the therapeutic objectives proposed by the ATP-III in a high number of patients, especially when associated to statins.

Lung cancer in a health area of Spain: incidence, characteristics and survival.

To examine the incidence, characteristics, therapeutic approach and survival of diagnosed lung cancer (LC) in the Santiago de Compostela Health Area. A retrospective study was carried out on LC for a period of 3 years. Of the 481 cases collected, 92.7% were male. The median age was 66.93 years. The crude incidence for men and women was 80.71 and 5.84 per 100,000 inhabitants respectively. Among the non-small cell lung cancers (NSCLC), 68.1% were diagnosed in stage IIIB or IV. The cancer had already spread in 62.2% of the small cell lung cancer (SCLC). Chemotherapy was used in 51.6% of patients. The survival probability from the first to the fifth year was 47.7%, 24.3%, 12.9%, 10% and 8.9% respectively. The median survival at 5 years was 12.12 months for NSCLC, rising to 29.8 months in stage I, and 8.85 months in SCLC. In our Health Area LC occurs more often in men, in whom the prevalence of smoking is very high. The most common histology type was squamous cell carcinoma. In the majority of cases, the diagnosis is made in the advanced stages, which accounts for the low percentage of surgical treatments and the short survival.

Nutritional Risk and Mortality at One Year for Elderly Patients Hospitalized with Nonvalvular Atrial Fibrillation. Nonavasc Registry.

OBJECTIVES: To determine whether nutritional risk is associated with the mortality of elderly patients hospitalized with nonvalvular atrial fibrillation (NVAF). DESIGN: Prospective, multicenter cohort study. SETTING: Internal medicine departments in Spain. PARTICIPANTS: Inpatients >75 years with NVAF. MEASUREMENTS: We measured the thrombotic and hemorrhagic risk at admission using the CHA2DS2-VASc and HAS-BLED scales, respectively, and the nutritional risk with the controlling nutritional status (CONUT) index. We established 4 degrees of nutritional risk: null (CONUT score 0-1 point), low (2-4 points), moderate (5-8 points) and high (9-12 points). We also conducted a 1-year follow-up. RESULTS: We included 449 patients, with a mean age of 85.2(5.2) years. The nutritional risk was null for 70(15.6%) patients, low for 206 45.9%), moderate for 152(33.8%) and high for 21(4.7%). At the end of one year, 177(39.4%) patients had died. The score on the CONUT index was higher for the deceased patients (4.6 vs. 3.6, p<0.001). The CONUT score (HR, 1.076; 95%CI 1.009-1.148; p=0.025), the Charlson index (HR, 1.080; 95%CI 1.017-1.148; p=0.013) and the presence of pressure ulcers (HR, 1.700; 95%CI 1.028-2.810; p=0.039) were independently associated with increased mortality at one year of follow-up. The prescription of oral anticoagulants at discharge was associated with lower mortality (HR, 0.440; 95%CI 0.304-0.638; p<0.001). CONCLUSIONS: More than a third of elderly patients hospitalized with NVAF have a moderate to high nutritional risk. These patients have greater mortality at the end of one year.

[Ureterostomy cytomegalovirus infection presenting as stoma ulceration in a kidney allograft receptor: a case report]. / Ureteritis por citomegalovirus en receptor de trasplante renal. Informe de un caso con presentación inusual.

Cytomegalovirus (CMV) is the most common viral infection affecting transplant patients, but urinary tract involvement has been rare. Only a few cases of symptomatic ureteritis have been reported in renal transplant recipients. In previous reports the presentation of CMV ureteritis is obstructive nephropathy, often in the absence of systemic illness, or rarely it may also mimic allograft rejection with minimal obstructive symptoms. We describe an additional case of CMV ureteritis in a patient with cutaneous ureterostomy. The unusual clinical presentation with urinary infection symptoms and ureterostomy stoma ulceration constitute a very particular presentation. The increasing report cases with CMV ureteritis suggest an increase of this post-transplant complication.

[Do we define the COPD correctly?]. / Definimos correctamente la EPOC?

Chronic obstructive pulmonary disease (COPD) is a very common disease which prevalence is increasing and in a nearly future it will represent a socio-sanitary problem. This article s objective is to make a reflexion about the concept COPD, for the physicians contribute to their divulgation to the population and very specially to help to the tobacco desertion. Besides we want to reveal that the term has been well-finished due to the advance in the knowledge of aetiology, physiopathology, and radiology techniques. Although, we think that the acronym still includes entities with a very different features. We hope to clarify this concept in the future, establishing different phenotypes and mainly with molecular biology.

La docencia sobre cronicidad en las facultades de Medicina: una revisión de la situación actual / Teaching about chronicity in medical schools — A review of the current situation

En las últimas décadas, el progresivo envejecimiento de la población en los países desarrollados ha provocado un aumento significativo del número de personas con al menos una enfermedad crónica. Como consecuencia, es fundamental que la formación pregrado en Medicina aporte conocimientos sobre la cronicidad, de forma que los médicos puedan proporcionar un manejo adecuado a estos pacientes. A pesar de ello, la presencia de la cronicidad en los currículos formativos de las facultades de Medicina es escasa y muy variable. Este trabajo consistió, por un lado, en una revisión de los programas formativos de las principales facultades de Medicina de cada continente, con el objetivo de identificar si incluían aspectos relacionados con la cronicidad y, por otro, en una revisión bibliográfica enfocada a identificar proyectos educativos en el campo de la cronicidad. La presencia de la cronicidad en los planes de estudio de la mayoría de las facultades de Medicina es marginal y solo unas pocas universidades incluyen habilidades o competencias específicas vinculadas a este campo. En la mayoría de los casos en los que sí aparece, este tema se refleja como una competencia global y transversal que los estudiantes deben adquirir a lo largo de toda su formación. La revisión bibliográfica identificó 21 artículos sobre proyectos docentes innovadores sobre cronicidad. Las principales características de los proyectos analizados son: el contacto directo con pacientes crónicos, la mayoría de las veces como «mentores de salud», el papel del estudiante como profesor y la evaluación y retroalimentación continuas de todos los participantes. Algunas experiencias previamente publicadas avalan la utilidad de metodologías innovadoras para una mejora en el abordaje de este campo en la práctica médica diaria. A pesar de la situación actual, en la que los pacientes crónicos consumen la mayor parte de los recursos sanitarios, la presencia de la cronicidad en las facultades de Medicina es marginal (AU)

Hospital at home for acute respiratory patients.

BACKGROUND: The issue of "hospital at home" (HAH) for acute respiratory patients is one that is still being debated, partly because economic, cultural and health service differences between locations imply that HAH schemes need to be tailored to local situations. The aim of the present study was to analyze the feasibility and effectiveness of HAH for patients with acute respiratory disease at our institution. METHODS: Of all the patients admitted to our institution via the emergency department during a 34-day subject enrollment period, 25 with diagnoses of respiratory infection, pneumonia, pulmonary insufficiency or exacerbated chronic obstructive pulmonary disease who were living within 25 km of our center and who were willing to receive HAH care were assigned to HAH. Fifty sex-matched controls with the same diagnoses were given conventional hospital care (CHC) as inpatients. The dependent variables evaluated included time to discharge, readmissions within 3 months and deaths within 3 months. RESULTS: There were no significant differences between the HAH and CHC groups with regard to age, diagnoses, physical and analytical findings, or co-morbidity, or with regard to deaths (HAH 16%, CHC 10%) or readmissions (HAH 17%, CHC 24%). Time to final discharge was significantly shorter for HAH patients (7 days) than for CHC patients (12 days). Some 95% of the HAH patients were satisfied and would choose HAH again. CONCLUSIONS: HAH seems feasible for appropriately selected acute respiratory disease patients presenting in our emergency department. It frees hospital beds for other patients, its readmission and mortality rates are no higher than for conventional hospitalization, and, in general, it is favorably evaluated by patients.

Ultrasound in the diagnosis of asymptomatic hyperuricaemia and gout. / La ecografía en el diagnóstico de la hiperuricemia asintomática y la gota.

The increase in serum urate concentrations (hyperuricaemia, ≥7.0mg/dL) creates crystals, which promote inflammation and joint lesions. Ultrasonography can reveal these urate deposits. The presence of crystals suggests that a patient with hyperuricaemia is actually experiencing asymptomatic gout, and that a patient with gout without subcutaneous tophi could experience tophaceous gout. The information offered by ultrasound (double contour sign and hyperechoic concretions mimicking clouds) enables a more specific classification of hyperuricaemia and gout. Additionally, this information can lead to relevant changes in terms of the diagnosis and therapeutic approach for patients with hyperuricaemia and gout.

Antithrombotic treatment in elderly patients with atrial fibrillation. / Tratamiento antitrombótico en el paciente anciano con fibrilación auricular.

Atrial fibrillation (AF) in the elderly is a complex condition due to the high number of frequently associated comorbidities, such as cardiovascular and kidney disease, cognitive disorders, falls and polypharmacy. Except when contraindicated, anticoagulation is necessary for preventing thromboembolic events in this population. Both vitamin K antagonists and direct oral anticoagulants (dabigatran, rivaroxaban and apixaban) are indicated in this context. Renal function should be closely monitored for this age group when these drugs are used. In recent years, various clinical practice guidelines have been published on patients with AF. The majority of these guidelines make specific recommendations on the clinical characteristics and treatment of elderly patients. In this update, we review the specific comments on the recommendations concerning antithrombotic treatment in elderly patients with nonvalvular AF.

Evolution of left ventricular hypertrophy and function during long-term treatment of systemic hypertension with enalapril.

Continued treatment of hypertensive patients with enalapril reduced left ventricular (LV) hypertrophy steadily over a period of 5 years (by which time gross structural parameters were normal) and produced no further reduction during the following 2 years. Temporary suspension of treatment after 5-year follow-up gave rise to an increase in blood pressure, and to deterioration of LV isovolumic relaxation time and deceleration of the ventricular filling E wave, both of which chiefly reflect the active relaxation of the ventricle.

Effects on left ventricular mass and function of low doses of enalapril for systemic hypertension.

After 7 years of treatment with 20 mg of enalapril twice daily, regression of the initial left ventricular hypertrophy in a group of 24 patients with essential arterial hypertension was achieved: gradual reduction in the dosage to 10 or 5 mg twice daily caused no worsening of either blood pressure or ventricular structure or function.

Maintenance of blood pressure control and left ventricular performance with small doses of enalapril.

Enalopril treatment (20 mg every 12 hours) of 24 patients with essential hypertension and left ventricular (LV) hypertrophy established normal blood pressure (BP) after 8 weeks, and after 7 years had reduced LV mass index by 39% from 148 +/- 34 to 90 +/- 16 g/m2, and had normalized LV structure and function and QT dispersion. Stepwise reduction of the enalapril dosage from 40 to 30, 20, 10, and 5 mg/day during the eighth year caused no significant changes in BP, LV structure, LV systolic function, or QT dispersion, which all likewise remained unaltered during a further year of the 5-mg/day regimen. We conclude that for hypertensive patients in whom prolonged treatment with standard doses of enalapril has normalized BP, LV structure and function, and QT dispersion, significantly smaller doses are sufficient to maintain these cardiovascular achievements.

Factors in the pathogenesis of tumors of the sphenoid and maxillary sinuses: a comparative study.

OBJECTIVES/HYPOTHESIS: To explain the processes that lead to the development of tumors in the maxillary and sphenoid sinuses. STUDY DESIGN: A 32-year review of the world's literature on neoplasms of these two sinuses and a randomized case-controlled study comparing the normal mucosal architecture of the maxillary to the sphenoid sinus. METHODS: Analysis of a 32-year world literature review reporting series of cases of maxillary and sphenoid sinus tumors. Tumors were classified by histological type and separated into subgroups if an individual incidence rate was reported. Histomorphometry of normal maxillary and sphenoid sinus mucosa was performed in 14 randomly selected patients (10 sphenoid and 4 maxillary specimens). Specimens were fixed in 10% formalin, embedded in paraffin, and stained with periodic acid-Schiff (PAS) and hematoxylin. Histomorphometric analysis was performed with a Zeiss Axioscope light microscope (Carl Zeiss Inc., Thornwood, NY) mounted with a Hamamatsu (Hamamatsu Photonics, Tokyo, Japan) color-chilled 3 charge coupled device digital camera. The images were captured on a 17-inch Sony (Sony Corp., Tokyo, Japan) multiscan monitor and analyzed with a Samba 4000 Image Analysis Program (Samba Corp., Los Angeles, CA). Five random areas were selected from strips of epithelium removed from each sinus, and goblet and basal cell measurements were made at magnifications x 100 and x 400. RESULTS: The literature review revealed that the number and variety of tumors in the maxillary sinus are much greater than those in the sphenoid. The incidence of metastatic lesions to each sinus is approximately equal. No recognized pattern of spread from any particular organ system could be determined. On histomorphometric study there were no statistically significant differences between the sinuses in the concentration of goblet cells, basal cells, or seromucinous glands. CONCLUSIONS: Factors involved in the pathogenesis of tumors of the maxillary and sphenoid sinuses include differences in nasal physiology, embryology, morphology, and topography. There are no significant histological differences in the epithelium and submucous glands between the two sinuses to explain the dissimilar formation of neoplasms.

Isolated sphenoid sinus disease: an analysis of 132 cases.

Solitary involvement of the sphenoid sinus is a relatively uncommon entity. A series of 132 patients with isolated sphenoid disease accumulated over a 22-year period is reported. A retrospective chart review was performed with special attention to the patients' presenting signs, symptoms, and radiographic findings. There were 80 patients with inflammatory disease, 38 with neoplasms, four with fibroosseous disorders, and 10 with traumatic and developmental lesions. The most common presenting symptom was headache, followed by visual changes and cranial nerve palsies. Cranial nerve abnormalities were encountered in 12% of the inflammatory cases, 60% of the benign tumors, and 57% of the malignant tumors. Radiographically, bone remodeling was associated with chronic inflammatory disease, especially mucoceles. Bone erosion was found principally with neoplastic disease, occurring rarely with mucoceles. Extension was associated with malignant tumors.

Management of embossment following the frontal osteoplastic operation.

The deformity in the bony contour of the forehead following the osteoplastic flap procedure on the frontal sinus, termed embossment, occurs in a small but definite number of cases. This complication arises from the combined processes of resorption and deposition of bone following disturbance of the periosteum in performing the operation. A simple and highly reliable method of cosmetic correction employing acrylic cranioplasty has been successfully utilized in a series of cases without complications. The details of the operative technique will be outlined.

Role of the argon beam coagulator in facial rejuvenation surgery.

OBJECTIVE: To compare the hemostatic effectiveness of a new electrosurgical unit, the argon beam coagulator, with current methods of electrocoagulation. DESIGN: A nonrandomized control trial of 20 patients undergoing rhytidectomy. SETTING: Two academic tertiary referral medical centers. PARTICIPANTS: Twenty male patients having moderate to major degrees of facial ptosis. INTERVENTION: All 20 patients underwent a standard rhytidectomy with hemostasis provided by the argon beam coagulator on the right side and conventional electrocoagulation on the left side. OUTCOME MEASURES: Improved hemostasis with minimal depth of injury, length of procedure, decreased blood loss, edema, and ecchymosis, and the ability to coagulate indiscriminately around and over neural tissue without damage (all listed in the literature as advantages of the argon beam coagulator). RESULTS: Poor hemostatic ability was observed with concomitant increased incidence of blood loss, edema and ecchymosis, major hematoma, and length of surgery. Also noted were increased rates of flap compromise and the potential for damage to vital neural structures. CONCLUSION: Our results do not agree with the list of advantages attributed to the argon beam coagulator in the literature.

Reduction columelloplasty. A new method in the management of the nasal base.

The nasal base is very complex secondary to the dynamic relationship between the skin, underlying muscle, and cartilaginous structures. Recently, we have employed a new method for refinement of the nasal base, which we name reduction columelloplasty. This procedure employs a full-thickness diamond-shaped tissue excision between the feet of the medial crura. The incision is carried down through the skin, depressor septi muscle, and adjacent soft tissue. Following en bloc removal, the defect is carefully closed in a vertical orientation, approximating the medial crura of the lower lateral cartilages. As in the open rhinoplasty approach, the scar produced by this technique is of negligible importance if it is closed using proper techniques of skin eversion and early suture removal. We have found this procedure to be an extremely reliable method for narrowing splayed medial crura, increasing the nasolabial angle, modifying the shape of the nares, and for increasing tip projection.

Reconstruction of orbital floor fractures with maxillary bone.

OBJECTIVE: To evaluate the use of autogenous maxillary bone for the repair of orbital floor defects secondary to blunt facial trauma. DESIGN: Retrospective case series of 41 patients with a mean follow-up of 1.7 years. SETTING: Major metropolitan teaching hospital. PATIENTS: Forty-one consecutive patients who underwent repair of orbital floor fractures with maxillary antral wall bone grafts. MAIN OUTCOME MEASURES: Presence of diplopia, orbital dystopia, implant extrusion, enophthalmos, infection, and donor site complications. RESULTS: On follow-up clinical examinations, none of the 41 patients presented with any evidence of orbital dystopia or complications relative to the implant or donor site. Two patients had persistent enophthalmos, and 4 had persistent infraorbital nerve paresthesia. Postoperative computed tomographic scans in 12 patients revealed an adequate maintenance of orbital volume without any evidence of resorption of the graft. CONCLUSION: The use of maxillary antral wall bone for the repair of orbital floor fractures is a highly reliable technique that carries minimal morbidity.

Management of bilateral glottic tumors.

OBJECTIVE: To compare the rates of cure and complication and the time to decannulation and deglutition in patients undergoing resection of bilateral glottic tumors. DESIGN: A 22-year, nonrandomized, prospective, retrospective analysis. SETTING: Two academic tertiary care referral centers. PARTICIPANTS: Seventy-two patients with bilateral glottic carcinoma were treated using bilateral hemilaryngectomy. Depending on the size of the tumor and the extent of thyroid cartilage resection, patients underwent 1 of 3 methods of reconstruction: group 1, placement of an anterior commissure stent (34 patients); group 2, epiglottic laryngoplasty (15 patients); and group 3, staged posterior thyroid alar transposition laryngoplasty (23 patients). INTERVENTION: Resection and reconstruction of 72 larynges with bilateral glottic tumors using the bilateral hemilaryngectomy procedures. MAIN OUTCOME MEASURES: Acceptable rates of cure and complication, intervals to decannulation and deglutition, and quality of speech. RESULTS: High rates of tumor control and cure, low rates of recurrence and complication, acceptable time to decannulation and deglutition, and adequate quality and intelligibility of speech. CONCLUSIONS: Bilateral vocal cord carcinoma can be treated surgically with a high degree of tumor control and cure. The use of all 3 methods maintained laryngeal function with regard to tracheal decannulation, oral alimentation, and speech intelligibility.
