RESUMO

According to the WHO (World Health Organization), lung cancer is the leading cause of cancer deaths globally. In the future, more than 2.2 million people will be diagnosed with lung cancer worldwide, making up 11.4% of every primary cause of cancer. Furthermore, lung cancer is expected to be the biggest driver of cancer-related mortality worldwide in 2020, with an estimated 1.8 million fatalities. Statistics on lung cancer rates are not uniform among geographic areas, demographic subgroups, or age groups. The chance of an effective treatment outcome and the likelihood of patient survival can be greatly improved with the early identification of lung cancer. Lung cancer identification in medical pictures like CT scans and MRIs is an area where deep learning (DL) algorithms have shown a lot of potential. This study uses the Hybridized Faster R-CNN (HFRCNN) to identify lung cancer at an early stage. Among the numerous uses for which faster R-CNN has been put to good use is identifying critical entities in medical imagery, such as MRIs and CT scans. Many research investigations in recent years have examined the use of various techniques to detect lung nodules (possible indicators of lung cancer) in scanned images, which may help in the early identification of lung cancer. One such model is HFRCNN, a two-stage, region-based entity detector. It begins by generating a collection of proposed regions, which are subsequently classified and refined with the aid of a convolutional neural network (CNN). A distinct dataset is used in the model's training process, producing valuable outcomes. More than a 97% detection accuracy was achieved with the suggested model, making it far more accurate than several previously announced methods.

RESUMO

Microscopic polyangiitis is a small vessel vasculitis, associated with myeloperoxidaseantineutrophil cytoplasmic antibody. It rarely occurs in children. Central nervous system involvement in pediatric microscopic polyangiitis is not a well known entity with perhaps only five cases till date. We hereby present a 14-year-old girl with arthralgia, seizure, leukocytoclastic vasculitis, interstitial lung disease secondary to recurrent pulmonary hemorrhage, pauci-immune glomerulonephritis and high titers of MPO-ANCA, hence diagnostic of microscopic polyangiitis. Magnetic resonance imaging of brain showed diffuse parenchymal involvement which resolved at six months with development of new foci of microhemorrhages in different stages of evolution, reminiscent of vasculitis.

RESUMO

AIM: To determine sexual dysfunctions and urinary symptoms in male ankylosing spondylitis (AS) patients and their association with various disease and patient factors. METHODS: In this prospective case control study conducted at a tertiary care teaching institution, 100 males with AS were compared to 100 controls using International Index of Erectile Function-15 (IIEF), International Prostate Symptom Score (IPSS), Hospital Anxiety and Depression Scale (HADS) and a global question for overall relationship with their partners. Bath AS Functional Index (BASFI), visual analogue scale pain scores, patient global assessment scale and Bath AS Disease Activity Index were also assessed in the AS group. Chi-square test, unpaired t-test and univariate and multivariate binary logistic regression analyses were used to analyze the data. RESULTS: Anxiety, depression, erectile dysfunction (ED), orgasmic dysfunction, intercourse dissatisfaction, overall sexual dissatisfaction, altered overall relationship with partner and lower urinary tract symptoms (LUTS) were significantly (P < 0.05) higher in the AS group as compared to controls. Sexual desire, severe LUTS and bothersome LUTS (quality of life score > 2) were not different (P = 0.76, 0.82 and 0.30 respectively) between the two groups. ED was associated with anxiety, depression, longer disease duration, higher BASFI and higher age in AS patients (P = 0.02, 0.001, 0.02, 0.003 and 0.001 respectively). CONCLUSIONS: AS is associated with higher incidence of sexual dysfunction in male patients. ED is associated with anxiety, depression, longer duration of disease, higher BASFI score and higher age in AS patients.
