Introduction. Pneumoscrotum is a rare clinical entity. It presents with swollen scrotal sac and sometimes with palpable crepitus. It has many etiologies. One of them is due to blunt trauma of the thoracic cage, causing pneumothorax and/or pneumomediastinum. Case Presentation. We report the case of an 82-year-old male who was transferred to the Emergency Department with signs of respiratory distress after a blunt chest trauma. A CT scan was obtained, and bilateral pneumothoraces with four broken ribs were disclosed. Subcutaneous emphysema expanding from the eyelids to the scrotum was observed, and a chest tube was inserted on the right side with immediate improvement of the vital signs of the patient. Discussion. Pneumoscrotum has three major etiologies: (a) local introduction of air or infection from gas-producing bacteria, (b) pneumoperitoneum, and (c) air accumulation from lungs, mediastinum, or retroperitoneum. These sources account for most of the cases described in the literature. Treatment should be individualized, and surgical consultation should be obtained in all cases. Conclusion. Although pneumoscrotum itself is a benign entity, the process by which air accumulates in the scrotum must be clarified, and treatment must target the primary cause.

In unilateral cases of papillary cystadenoma of epididymis such as our patient's, literature advocates that no further examinations and expensive genetic testing is required.

Background: One of the main factors in response to hypoxia in the tumor microenvironment is the hypoxia-inducible factor (HIF) pathway. Although its role in other solid tumors, particularly renal cell carcinoma, has been sufficiently elucidated, it remains elusive in prostate cancer. The aim of the present study was to investigate the expression of main proteins involved in this pathway and determine the correlation of the results with clinicopathological outcomes of patients with prostate cancer. Methods: The immunohistochemical expression of HIF-1a, HIF-2a and their regulators, prolyl hydroxylase domain (PHD)1, PHD2 and PHD3 and factor inhibiting HIF (FIH), was assessed on a tissue microarray. This was constructed from radical prostatectomy specimens, involving both tumor and corresponding adjacent non-tumoral prostate tissues from 50 patients with localized or locally advanced prostate cancer. Results: In comparison with non-tumoral adjacent tissue, HIF-1a exhibited an equal or lower expression in 86% of the specimens (P = 0.017), while HIF-2a was overexpressed in 52% (P = 0.032) of the cases. HIF-1a protein expression was correlated with HIF-2a (P < 0.001), FIH (P = 0.004), PHD1 (P < 0.001), PHD2 (P < 0.001) and PHD3 (P = 0.035). HIF-2a expression was positively correlated with Gleason score (P = 0.017) and International Society of Urological Pathologists (ISUP) grade group (P = 0.022). Conclusions: The findings of the present study suggest a key role for HIF-2a in prostate cancer, as HIF-2a expression was found to be correlated with Gleason score and ISUP grade of the patients. However, further studies are required to validate these results and investigate the potential value of HIF-2a as a therapeutic target in prostate cancer.

Introduction. In patients with erectile dysfunction (ED), inflatable penile prosthesis (IPP) surgery is regarded as the gold standard treatment in medically refractory cases or where its conservative treatment options are contraindicated. Despite improvements in surgical technique and implanted materials, IPP surgery retains a substantial complication rate. The aim of the study was to record and grade the postoperative complications of IPP implantation according to a modified Clavien system.Methods. A total of 60 three-piece IPP implantations were performed between 2007 and 2013 by a single surgeon. The primary outcome was to stratify the early (first 30 days) complications into five categories using the modified Clavien-Dindo classification system. A secondary aim was to record the long-term adverse events and to identify possible factors related to complication occurrence.Results. Overall, there were 21 (35%) postoperative complications in 17 of 60 men (28.3%), with 15 adverse events occurring early after surgery. In terms of late complications, there were six (10%) major complications managed by either revision surgery or removal of the prosthesis.Conclusion. This study utilizes a validated morbidity scale thus overcoming problems of previous studies reporting IPP surgery complications. The modified Clavien classification system easily aids in assessing and comparing accurately patients’ postoperative complications, thus improving management and prevention.
