AI Article Synopsis
- Obese patients show a lower prevalence of varicoceles detected via ultrasound compared to normal weight individuals, suggesting that excess body weight affects detection rates.
- The study analyzed 1,079 men aged 18-40, finding that those with a higher body mass index had fewer diagnosed varicoceles, with significant differences observed between normal and obese categories.
- The results imply that the discrepancy in varicocele prevalence among different weight groups is likely not linked to the difficulty of physical examinations but is influenced by other unidentified factors.
Article Abstract
Purpose: Research shows that obese patients have a lower incidence of varicoceles. Increased adipose tissue, which makes physical examination difficult, was hypothesized to be the cause. We evaluated the varicocele incidence on routine scrotal ultrasound to see whether difficult physical examination was causative.
Materials And Methods: We reviewed all scrotal ultrasounds from the last 2 years for men 18 to 40 years old who had a recorded body mass index. Physical examination findings and the indication for ultrasound were included. We used standard criteria for ultrasound detected varicoceles. National Institutes of Health criteria was used to classify patients as normal-body mass index less than 25 kg/m(2), overweight-25 to 30 or obese-greater than 30.
Results: Of the 1,079 patients 330 (30.6%) had an ultrasound detected varicocele. Mean ± SD body mass index in those with vs without a varicocele was 26.7 ± 3.8 vs 26.0 ± 3.7 kg/m(2) (p = 0.04). On physical examination 171 patients (16.0%) had a varicocele. Mean body mass index in those with vs without a varicocele on physical examination was 26.6 ± 3.7 vs 26.4 ± 3.9 kg/m(2) (p = 0.09). We calculated varicocele frequency by body mass index for ultrasound detected varicoceles only. Of 374 normal weight patients 129 (34.5%) had a varicocele while in the overweight and obese groups 163 of 535 (30.6%) and 43 of 170 (25.6%), respectively, had a varicocele. The difference between normal and obese patients was statistically significant (p = 0.04).
Conclusions: Obese patients have a lower prevalence of varicoceles detected by ultrasound. The lower prevalence is independent of physical examination and more likely due to another factor.

Background: Acute pain management is critical in postoperative care, especially in vulnerable patient populations that may be unable to self-report pain levels effectively. Current methods of pain assessment often rely on subjective patient reports or behavioral pain observation tools, which can lead to inconsistencies in pain management. Multimodal pain assessment, integrating physiological and behavioral data, presents an opportunity to create more objective and accurate pain measurement systems.

Recently, proximal fibular osteotomy (PFO) has emerged as a less invasive and more cost-effective alternative. This study compares the outcomes of HTO and PFO to evaluate whether PFO can deliver results comparable to HTO in similar patient populations.

Objective: To compare the effectiveness of ear acupuncture with laser and needles in the treatment of anxiety in university students in the post-pandemic context of Covid-19, as well as to evaluate the possible symptoms or adverse reactions triggered by the interventions.
Method: Randomized clinical trial carried out with 126 university students, allocated to the "Needle" (control) and "Laser" (experimental) groups. Five ear acupuncture sessions were performed.
