Staging a great escape -Incidentally detected renal urothelial carcinoma with extensive squamous metaplasia presenting as pyonephrosis
We report the case of a 70-year-old female patient who presented with flank pain, pyuria, fever, and a unilateral nonfunctioning kidney with nephrolithiasis and pyonephrosis on pyelography. Routine imaging failed to identify a mass lesion. In an Indian setting, the clinical differential of tuberculosis was considered likely. A nephrectomy was performed in view of the poor perfusion and functional status of the right kidney. Histopathological examination of the kidney showed a tumor of urothelial origin arising at the renal pelvis displaying extensive squamous metaplasia. Such a near total metaplastic change is rare and has hitherto been undescribed in the renal pelvis. Activation of pleuripotent urothelial stem cells in the setting of chronic irritation and inflammation may be the pathogenetic process behind such an occurrence.

Authors: Ahmadianpour MV, Mowla J, Sotoodehnejadnematalahi F, Raheb J Abstract Studies on the blood of patients with prostate cancer using Dynamic Light Scattering (DLS) and corona protein size changes have shown that this test is highly specific and sensitive, but this method has not been studied in Iran, and therefore this study intends to perform this procedure using gold nanoparticles in prostate cancer detection. Blood samples of 60 male subjects aged 40-90 years were collected from 20 healthy, 20 benign and 20 prostate cancer patients. Optical scattering changes were measured by the level of gold nanoparticle...

Authors: Annunziato J, Shor D, Parikh S Abstract Heterotopic ossification (HO) is excess bone growth in soft tissues, typically juxta-articular and interfascicular, with varying incidence. This excess bone growth has been well-documented in cases of traumatic amputation but less frequently observed in cases of nontraumatic amputation. Symptomatic heterotopic ossification usually includes pain during prosthetic use with management involving prosthetic adjustments for comfort. This atypical case highlights a patient with a nontraumatic amputation and a proximal-oriented large spur formation that was not painful with ...
Authors: Headman ZC, Matson MC, Schneider RP, Potter JL, Loguda-Summers DL, Bhatia S, Kondrashova T Abstract Context: Various forms of simulation-based training, including training models, increase training opportunities and help assess performance of a task. However, commercial training models for lumbar puncture and epidural procedures are costly. Objective: To assess medical students' and residents' perception of 3-dimensional (3D)-printed lumbar, cervical, and pelvic models for mastering joint injection techniques and to determine the utility of ultrasonography-guided needle procedure training. Methods:...
Conclusion: After the third relapse of HGSC, cytotoxic chemotherapy did not prolong survival but was associated with substantially increased healthcare costs. PMID: 32223298 [PubMed - as supplied by publisher]
