The incidence of osteoarticular TB is much lower than that of the lung, representing 1-2% of TB cases and 10% of extrapulmonary TB cases, so it is often not considered for the differential diagnosis of patients with joint disease. Its diagnosis is difficult and is based on clinical, radiologica l, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and specimens, in most cases, difficult to obtain, so the diagnosis is often simply presumptive. Joint tuberculosis in early stages presents nonspe cific clinical and imaging manifestations. This can lead to the progression of the local disease, generating severe osteoarticular lesions and, finally, joint destruction. We present the case of a 60-year-old patient who underwent surgery due to clinical and imaging manifestations compatible with a rotator cuff tear, and whose torpid postoperative evolution led to the bacteriological diagnosis of proximal humerus tuberculosis.Endoscopic fullthickness resection is a technique that allows in block resection of colonic lesions in patients in whom conventional endoscopic methods such as endoscopic mucosal resection or endoscopic submucosal dissection have failed. We present a case of a 75-year-old man with history of a difficult-to-resect colon adenoma. He had undergone two previous failed attempts of endoscopic mucosal resection due to non-lifting sign in another center. We successfully performed an endoscopic full-thickness resection procedure, avoiding unnecessary surgery.True splenic aneurysms are saccular dilations of all the layers of the splenic artery, more common in women, pregnancy and portal hypertension. They are usually asymptomatic and diagnosed incidentally during the study of other abdominal diseases. Up to 10% may present with rupture, which implies a high morbidity and mortality. Treatment of splenic aneurysms is still a subject of controversy and there is a great variety of therapeutic modalities. We present two cases of patients with splenic aneurysms one who presented with rupture and the other one incidentally diagnosed. Both were treated with endovascular embolization achieving optimal results. Although the utility of this therapy has not been assessed for giant or ruptured aneurysms, it allowed us to solve these scenarios in a secure and effective way, with minimum morbidity and mortality.Whipple's disease is a chronic mutisystem disease caused by the bacteria Tropherima whipplei. Approximately 1200 cases have been described in the literature. The worldwide incidence is estimated at 9.8 cases per million people. Data from South America and Europe show that it affects middle-aged males. It is believed that host immunological factors rather than agent genotypic traits influence the course of the infection. Since the clinical characteristics are usually nonspecific and the wide spectrum of manifestations in individual organs may be underestimated, the diagnosis remains challenging. We present a case with multisystem compromise confirmed by histopathology. We consider its publication important given the few cases documented in South America and the relevance of bearing in mind the importance of an early diagnosis for a prompt treatment that improves the prognosis of this rare disease.New drug discovery involves preclinical studies to demonstrate its effectivity and safety for further tests in humans. This leads to the need to develop technologies that take advantage of the new analytical tools available within a context where the results of the tests carried out are fully documented, under auditable systems of good laboratory practice. This review updates and describes some of the tests carried out in the preclinical stage of the development of a new drug and the current state of the analytical technology used to measure different blood biomarkers of interest. Biomarker parameters were analyzed at the physiological level, considering both the validation regulations of the analytical techniques used for their determination as the problems that arise when trying to apply them, since many of these biomarkers are endogenous compounds in the used matrices.After a stressful event, adaptative mechanisms are carried out to support vital functions. Ruxotemitide chemical structure Hypothalamic-pituitary-adrenal axis plays a key role in stress response regulating metabolism, cardiovascular function and immune system. This review addresses pathophysiological changes of the adrenal axis during critical illness, recognizing limitations of methods applied for its evaluation in this special context and defining indications for corticosteroid replacement in critically ill patients. The concept of relative adrenal insufficiency should be abandoned; cosyntropin stimulation test should not be performed for diagnosis of adrenal insufficiency in critical illness nor for establishing the need of treatment.The choice of a contraceptive method considered highly effective in epileptic women of childbearing age is important, since it requires taking into account the eligibility criteria and the possible pharmacological interactions between certain types of anti-seizure drugs (mainly enzyme inducers drugs of the hepatic system P450 such as carbamazepine, phenytoin, phenobarbital, oxacarbamazepine, eslicarbazepine, rufinamide, lacosamide and topiramate in high doses) and certain contraceptive methods (oral contraceptives combined or only with progesterone and subdermal progesterone implants), which may accelerate the metabolism of the latter with the consequent risk of failure or vice versa, reduction of plasma concentration (such as lamotrigine) predisposing to seizures, risk of unwanted pregnancies, abortions, teratogenicity due to valproato, maternal- fetal complications and difficulty in the management of epileptic activity during pregnancy. In case of prescribing both medications, the combined use with a barrier method should be considered or the use of a depot injection of medroxyprogesterone acetate or intrauterine device as contraception should be considered. Family planning counseling at the first visit has been shown to influence the choice of the contraceptive method and the early initiation of folic acid in the search for fertility. In conclusion, the different therapeutic options should be analyzed together with the epileptic patients in order to achieve and optimize the best goal for each one.
