Locally advanced pancreatic cancer (LAPC) has several definitions, but it is essentially a non-metastatic tumor, in which the initial surgical resection is not considered beneficial due to the extensive vascular involvement and consequent high chance of a nonradical resection. The introduction of chemotherapy with calcium leucovorin, fluorouracil, irinotecan hydrochloride and oxaliplatin (FOLFIRINOX) and gemcitabine-nab (nanoparticle albumin-bound)-paclitaxel (gem-nab) had very important implications for the management of patients with LAPC. After 4 to 6 months of induction chemotherapy, a large proportion of them have stable disease or even tumor regression, allowing to rescue those who initially were not candidates for surgery, with 30-35 months overall survival after surgery.

Phenylketonuria, also known as PKU, is the most frequent congenital inborn error of metabolism. The severe form or classic PKU untreated causes intellectual disability, although with the early detection programs in the neonatal period, diagnosis and treatment prevent the appearance of the symptoms. Despite early diagnosis and treatment we have observed some neurotoxicity in treated PKU patients. ⋯ White matter alterations in early treated PKU patients have an important role in neurological manifestations. The treatment of PKU is for life and is based on the reduction of foods containing Phe combined with the administration of a special formula or tetrahydrobiopterin (BH4) treatment. New therapeutic options will be analyzed.

The early identification of patients with palliative needs has shown benefits in terms of quality of life and treatment goals. No prospective methods have been applied in Argentina to identify palliative needs in cancer patients. The NECPAL tool combines the physician's own insight with objective indicators of disease progression and indicators of chronic advanced conditions. ⋯ In the multivariate model, the best predictors of mortality combining relevant indicators were: inpatients (HR 1.87; 95% CI 1.24-2.84; p = 0.003), initial diagnosis other than breast cancer (HR 2.04; 95% CI 1.23-3.40; p = 0.006), metastatic disease (HR 1.67; 95% CI 1.15-2.42; p = 0.007), functional deterioration (HR 1.95; 95% CI 1.28-2.97; p = 0.002), and malnutrition (HR 1.53; 95% CI 1.04-2.23; p = 0.02 9). The major breakthrough was the systematic prospective identification of palliative needs in cancer patients for the first time in Argentina. The NECPAL tool can improve the prediction of mortality in hospital settings.

Misdiagnosis is a challenging risk in young patients with ischemic stroke that leads to delayed recognition, prevents thrombolytic therapy and increases morbidity and mortality. To assess the frequency and reasons for misdiagnosis of ischemic stroke in young adults in the emergency department, we retrospectively evaluated 101 consecutive patients. The diagnosis required both the presence of an ischemic lesion in diffusion-weighted MRI as well as neurological symptoms. ⋯ The initial diagnosis was made by emergency physicians in 22 persons. The group with misdiagnosis had a significantly higher frequency of AD at 15 vs. 8 (p < 0.01), posterior territory involvement at 12 vs. 6 (p < 0.01), and female predominance. Misdiagnosis occurred in a third of young patients with an ischemic stroke and was more frequent in those with arterial dissection involving the posterior circulation and presenting with non-specific symptoms.

Case Reports
[Refractory colitis by Clostridium difficile treated with fecal microbiota transplant].
Clostridium difficile infection is an increasingly recognized cause of diarrhea in inpatients, frequently associated to high mortality. Vancomycin is the treatment of choice for all Clostridium difficile- associated diarrheas, with different degrees of severity. ⋯ Fecal microbiota transplantation has been shown to be successful in a series of cases of severe diarrhea associated with this organism. We present a case of refractory C. difficile infection successfully treated with fecal microbiota transplantation.
