Macroprolactinomas predominate in males in comparison to microprolactinomas, with greater trend to invasiveness than in females. The clinical treatment has been the first option to prolactinomas, in both macro and microadenomas, irrespective the sex. We compared clinical presentation, prolactin levels, neuroradiologic invasiveness and prolactinemia response of 23 men with prolactinomas subjected to clinical therapy (group 1) with 19 who went also through surgical and/or radiotherapeutic treatment (group 2). The statistical analysis was done by the tests of chi-square or exact of Fisher, in order to compare proportions, and by t of Student or Mann-Whitney, in order to compare means. The level of significance adopted was 5% (p<0.05). The two groups were similar regarding age (p=0.23), period between start of the first symptom and diagnosis (p=0.82), prolactin levels before treatment (p=0.41) and invasive macroadenomas proportion (p=0.096). There was significantly greater percentage of headache (p=0.009) and visual deficit (p=0.025) in group 2, as well as the drug usage (p=0.007) and observation (p=0.0005) periods were superior in this group. The variations of prolactin levels before and after therapy (p=0.49) as well as the percentage of prolactin normalization (p=0.20) did not show any significant difference when comparing the two groups. We conclude, emphasizing the relevance of precocious prolactinoma diagnostic in men, because of the demonstrated morbidity. We strengthen the use of dopamine agonist as the first therapeutic option irrespective the adenoma size.

When infants are admitted to the hospital with skull fractures, providers must distinguish between cases of accidental and abusive head trauma. Limited information about the incident is available in such cases, and witness statements are not always reliable. In this study, we introduce a novel, data-driven approach to predict fall parameters that lead to skull fractures in infants in order to aid in determinations of abusive head trauma.

Aim: The aim of this work was to quantify post-colonoscopy colorectal cancer (PCCRC) rates in National Health Service (NHS) Scotland using World Endoscopy Association guidelines, compare incidence between health boards and referral streams and explore comparisons in results with published data from other healthcare systems.
Method: This is a population-based cohort study using NHS Scotland data between 2012 and 2018. All people undergoing colonoscopy between 2012 and 2018 and subsequently diagnosed as having bowel cancer up to 3 years after their investigation were included.

In this work, bridge network model with Rayleigh distribution lifetimes is used. Two main techniques are calculated to upgrade this model: reduction and redundancy techniques. In order to compare the effectiveness of the various approaches, the survival function, the mean time to failure and gamma-fractiles for the original and upgraded model are calculated.

Objectives: The aims of this study were to describe the frequency of pleuropulmonary computed tomography (CT) findings in patients with IgG4-related disease (IgG4-RD) and to compare clinical and laboratory characteristics between patients with and without pleuropulmonary involvement in chest CT.
Methods: This is a study conducted within the IgG4-RD study group of the Argentine Society of Rheumatology (GESAR IgG4) cohort of patients with IgG4-RD. Member centers of the group were requested to submit pulmonary CT scans of the patients.

Objective: To develop predictive models for assessing deep vein thrombosis (DVT) risk among lumbar disc herniation (LDH) patients and evaluate their performances.
Methods: A retrospective study was conducted on 798 LDH patients treated at the First Hospital of Hebei Medical University from January 2017 to December 2023. The patients were divided into a training set (n = 558) and a test set (n = 240) using computer-generated random numbers in a ratio of 7:3.
