Purpose: The purpose of the study is to describe a bailout technical strategy to prevent below-the-knee (BTK) distal embolization during procedures with increased inherent risk using universally-available "off-the-shelf" devices.

Technique: A conventional retrograde access is obtained of the BTK target vessel where embolization protection is sought. Before starting any potential proximal maneuver with an associated significant risk of distal embolization (eg, atherectomy and mechanical thrombectomy), a low-profile balloon is inserted and inflated through the distal retrograde access, so that any debris resulting from the recanalization procedure is blocked by the stagnant column of blood generated by the inflated balloon.

Purpose: To describe a novel bailout technique to approach below-the-knee chronic total occlusions after a failed bidirectional recanalization attempt using the plantar loop maneuver in patients who are poor candidates for a retrograde puncture.

Technique: After a failure of recanalization of the opposite tibial artery using the plantar loop maneuver, an assisted direct retrograde transpedal approach can be performed regardless of poor vessel caliber or even arterial occlusion. After crossing the plantar arch, a low profile angioplasty balloon is used as a landmark for the pedal puncture and to give guidance for the wire advancement from the new access.

Background: This study was to describe the evolution of patients who underwent surgical treatment of drug- resistant occipital lobe epilepsy (OLE) at our institution.

Methods: We performed a retrospective analysis of data collected from electronic and paper clinical records of 20 patients who were diagnosed of OLE and underwent epilepsy surgery at our institution between 1998 and 2018. We also contacted patients by telephone and asked them to fill out a questionnaire about quality of life in epilepsy (QOLIE-10).

Article Synopsis
  • * A small fenestration is created on the sheath to allow for controlled navigation of the guidewire into the superficial femoral artery while maintaining correct alignment.
  • * This on-site modification provides a simple solution when typical techniques fail, making catheterization of the superficial femoral artery more reliable.

Purpose: To describe a simple maneuver to facilitate the retrograde puncture of challenging tibial vessels in the lower leg.

Technique: Because of the depth of the tibial vessels at the mid to upper calf, especially in obese or muscular patients, a 7- or 9-cm, 21-G micropuncture needle is often needed to reach the artery. However, the low profile of the needle contributes to its flexibility and therefore the tendency to bend as it progresses through the deep tissues, hindering access to the target vessel.

Background: Corrientes, a province of northeastern Argentina with endemic leprosy, has improved its epidemiological indicators, however, a study of the dynamics over time is lacking.

Objectives: We analysed data of 1308 leprosy patients between 1991 to 2014, and the forecast for 2020.

Methods: Descriptive statistics and stepwise Bayesian model selection were performed.

Article Synopsis
  • The study aimed to assess the clinical features and outcomes of pneumococcal meningitis in children under 16 in Lima, Peru, analyzing cases from 2006 to 2011.
  • Out of 44 cases, a significant 68.2% involved children under 2 years old, with a high fatality rate of 32.6%, mostly within the first two days; malnutrition also correlated with fatalities.
  • Over 40% of pneumococcal strains showed resistance to penicillin, with common serotypes being 6B, 14, 19F, and 23F, emphasizing the need for prompt diagnosis and effective vaccination.

Introduction: Obesity is a chronic, heterogeneous, multifactorial disease, which has sharply increased in prevalence in both developed and developing countries. This study aimed to estimate the prevalence of obesity and to identify socio-demographic risk factors associated with it, with special emphasis on diet.

Methods: Nutritional status, demographic characteristics, lifestyle habits, and food consumption patterns derived from a Food Frequency Questionnaire were investigated.

Background: The aim of this study was to evaluate nuclear factor-kappa B (NF-κB) expression as a biologic marker to predict local control in patients with head and neck squamous cell carcinoma (HNSCC) treated with radiotherapy or chemoradiotherapy.

Methods: The mRNA expression levels of the NF-κB family genes were determined with real-time-polymerase chain reaction in 77 patients with HNSCC treated with radiotherapy or chemoradiotherapy.

Results: The mRNA NF-κB (p65) expression in pretreatment tumors was significantly related to local control (p = .

The quality guidelines established in Primary Care Service Portfolios of Autonomous Communities were analysed. It was observed that there were similarities in the number and content of the controls in children over 2 years-old, time intervals of cardiovascular risk and breast cancer mammography screening. Variability was observed in the number of controls (from 2 to 8) recommended for infants less than 2 years old, in the time intervals of monitoring parameters of patients with risk factors (for example, glycosylated haemoglobin in the diabetic every 2, 6, or 12 months), in the time intervals in cervical cytology (every 3 or 5 years) and in the age periods of performing the cytology (from 15, 20, 25, or 30 years up to 55 or 60 years) or mammography (from 45 or 50 years up to 60 or 65 years).
