Foreskin trapped by zipper: a case report

We present an 84 year-old-male patient with foreskin trapped by his zipper. After several failed attempts with scissors, screwdriver and others we practise an elliptic incision to resolve the problem. Foreskin injuries are frequent in children but are rare in adult men. There are some techniques described for solving the problem using scissors, screwdriver, traction and surgery

Cutaneous metastases in renal cell carcinoma: a case report

Renal cell carcinoma is the most common form of malignant renal tumour and is extremely lethal. About 25% of the patients develop metastasis at the time of diagnosis, and in many cases during the course of the disease, affecting the lung, lymphatic ganglions, liver, and bone, with skin metastases being quite rare

To a paradigm shift to the evaluation of scientific activity into Higher Education

La evaluación actual de la actividad científica se lleva a cabo mediante un mismo patrón internacional. Esta circunstancia ha estimulado un notable número de investigaciones críticas. Sin embargo, la abundancia de críticas contrasta con la falta de propuestas alternativas. En este trabajo se presenta una síntesis de los inconvenientes observados en las prácticas de evaluación, identificando consecuencias negativas para la propia ciencia, sus miembros y su utilidad pública respecto a las Instituciones de Educación Superior. También se añade una revisión de voces alternativas. Finalmente, se propone un conjunto de ocho principios para ayudar a promover un cambio de paradigma.The current assessment of scientific activity is performed by the same international pattern. This has stimulated a remarkable number of critical researches. However, the abundance of critical publications contrasts with the lack of alternative proposals. This paper presents a synthesis of the drawbacks observed in assessment practices, identifying negative consequences for science itself, its members and its public utility, in reference to Higher Education Institutions. A review of alternative voices is also added. Finally, this paper proposes a set of eight principles to assist in promoting a paradigm shift

Calcium renal lithiasis: metabolic diagnosis and medical treatment

Calcium renal lithiasis is a frequent condition that affects the worldwide population and has a high recurrence rate. Different metabolic changes may trigger the onset of calcium stone disorders, such as hypercalciuria, hyperoxaluria, hyperuricosuria, hypocitraturia and others. There are also other very prevalent disorders that are associated with calcium calculi, such as arterial hypertension, obesity and loss of bone mineral density. A correct diagnosis needs to be obtained through examining the serum and urinary parameters of mineral metabolism in order to carry out adequate prevention and treatment of this condition. Once the metabolic diagnosis is known, it is possible to establish dietary and pharmacological treatment that may enable monitoring of the disease and prevent recurrence of stone formation. Some advances in treating this pathological condition have been made, and these include use of sodium alendronate in patients with calcium renal lithiasis and osteopenia/osteoporosis, or use of a combination of a thiazide with a bisphosphonate. In summary, calcium renal lithiasis often requires multidrug treatment with strict control and follow-up of patients
