Background: It is unknown how often prostate carcinomas are diagnosed as a result of urinary obstructive symptoms or whether prostate carcinomas diagnosed because of obstructive symptoms have a favorable or unfavorable prognosis. It is also unknown whether racial differences in obstructive symptoms could help explain why black men with prostate carcinoma are diagnosed with more advanced stages and grades of prostate carcinoma than are white men with prostate carcinoma.
Method: At a single Veterans Administration Medical Center, 478 consecutive cases of prostate carcinoma diagnosed between 1973 and 1985 were identified. The incidence of obstructive symptoms at diagnosis, racial differences in obstructive symptoms, and the survival of patients with and without obstructive symptoms, stratified by stage and grade, were determined. In addition, racial differences in the frequency of surgical intervention required to relieve the obstructive symptoms were determined.
Results: All patients diagnosed with Stage A prostate carcinoma and most (82%) patients diagnosed with Stage C prostate carcinoma had obstructive symptoms. Those diagnosed with Stage B and Stage D prostate carcinomas had with similar frequencies (53% and 55%, respectively) of obstructive symptoms. Survival, stratified by stage and grade, was similar for men with and without obstructive symptoms. The incidences of obstructive symptoms and the frequency of surgical intervention to relieve the obstructive symptoms, stage for stage, were similar for white and black men.
Conclusion: Survival, stratified by stage and grade, is not affected adversely by obstructive symptoms. Neither racial differences in the incidence of obstructive symptoms nor the frequency with which obstructive symptoms require surgical correction explain why black men with CAP consistently are diagnosed more frequently with Stage D prostate carcinoma and less frequently with Stage A CAP than white men with CAP.

Novel approach to treating calcified infrarenal aortic stenosis using intravascular lithotripsy without stenting.

Vascular Surgery Unit, S. Chiara Hospital, APSS Trento, Trento, Italy.
This case report presents the use of intravascular lithotripsy (IVL) in a 68-year-old woman with disabling bilateral claudication owing to a heavily calcified subocclusive stenosis of the infrarenal aorta. The patient had a history of tobacco use, dyslipidemia, and chronic obstructive pulmonary disease, with absent femoral pulses and severe arterial calcification. A 12-mm Shockwave L6 lithotripsy catheter was employed to treat the aortic lesion, resulting in a significant decrease in the aortic pressure gradient without the need for stenting.

An 84-year-old lady presented with 1 day history of sudden onset generalized abdominal pain, fevers, and peritonism. Computed tomography was suggestive of a mid-small bowel perforation associated with a distal ovoid soft tissue density structure without pneumobilia. An urgent laparotomy demonstrated two areas of jejunal diverticula necrosis and perforation associated with a 3 cm luminal mass in the proximal ileum, and proximal small bowel dilatation.

Objective: To assess and compare efficacy of 4-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) and X-ray hysterosalpingography (HSG) for fallopian tube examination.
Methods: Clinical data of patients with suspected tubal infertility, who underwent examinations in Qingdao Women and Children's Hospital from September 2021 to December 2023, were retrospectively analyzed. Of them, 40 patients received laparoscopy and dye test+ 4D-HyCoSy (4D-HyCoSy group), and 36 patients received laparoscopy and dye test +HSG (HSG group).
Background: Lipid Accumulation Product (LAP), which is derived from measurements of waist circumference and triglyceride (TG) levels, serves as a comprehensive indicator of lipid accumulation. Emerging research indicates that lipid accumulation dysfunction might significantly contribute to the pathogenesis of Chronic Obstructive Pulmonary Disease (COPD). Nevertheless, the investigation into the association between LAP and COPD risk is still insufficient, particularly in population-based research.

Objective: Vitamin B6 is involved in regulating a variety of biological reactions in cell metabolism, and possesses antioxidant and anti-inflammatory biological functions. 5'-pyridoxal phosphate (PLP) is the main biologically active form of vitamin B6. There is currently no research on the correlation between serum PLP levels and chronic obstructive pulmonary disease (COPD) prevalence.
