Renal cell cancer (RCC) has the ability to metastasize to various organs, including the anal canal which is reported to be the rarest location. An 88-year-old male patient who had previously been treated for right RCC subsequently developed distant metastases to the prostate, lungs, and small bowel. Four years following nephrectomy, the patient presented with a bleeding anal mass which was excised and has been proven to be an anal canal metastasis of RCC. Eight months post excision, regrowth occurred. The patient underwent stereotactic ablative body radiotherapy resulting in satisfactory regression during the 2-month follow-up period, without episodes of bleeding. The treatment options for metastatic post-nephrectomy disease should be considered with a multidisciplinary approach in order to achieve satisfactory symptom relief.

This study investigated the incidence and severity of hepatic osteody strophy in patients with posthepatitic liver cirrhosis, and the role of hepatocellular injury in bone loss. Twenty-four patients (15 females and 9 males, mean age 49 +/- 13 years) with posthepatitic cirrhosis were enrolled in this study. The control group consisted of 22 healthy age and sex matched adults. The bone mineral density (BMD) was evaluated by dual energy x-ray absorptiometry of the L1-L4 vertebral bodies. A detailed questionnaire was used to assess the epidemiological findings. A statistically significant decrease in BMD of the patients was observed. There were no significant differences in the alkaline phosphatase, parathyroid hormone, calcitonin, 25-hydroxyvitamin D, osteocalcin, free testosterone, luteinizing hormone, follicle stimulating hormone, and estradiol levels, oral calcium intake, urinary calcium, phosphorus and hydroxypyroline excretion between patients and controls. The control group smoked more cigarettes, consumed more coffee and meat, and were exposed the sun light for a longer period than the study group. Multiple regression analysis showed that osteopenia depends significantly on the extent of liver disease. The data shows that the patients with posthepatitic cirrhosis had osteopenia, and that cirrhosis was a direct and independent risk factor.

Purpose: To report the intraoperative corneal pachymetry changes during accelerated corneal cross-linking (A-CXL) in progressive keratoconus patients with thin corneas. Methods: Thirty-six eyes (mean age, 22.26 ± 4.02 years) with progressive keratoconic thin corneas (<400 μm without epithelium) who underwent A-CXL with ultraviolet (UV)-A (UVA) (9 mW/cm2) using isotonic riboflavin5-phosphate 0.1% with 1.1% hydroxypropyl methycellulose (RF-HPMC, MedioCROSS M) were included in this retrospective study. Intraoperative corneal pachymetric changes were noted before the procedure, after removal of epithelium, after RF-HPMC instillation, before and after UV irradiation. The mean of corneal pachymetric values were compared statistically. Results: The mean corneal pachymetry reduced from 415.72 ± 29.66 to 369.50 ± 23.45 μm after removal of the epithelium (p < 0.05). After the application of RF-HPMC solution the mean thinnest corneal pachymetry (TCP) increased to 412.89 ± 26.94 μm. Statistically significant increase was observed in TCP after saturation with RF-HPMC (p = 0.001). The mean corneal pachymetry before and after UVA irradiation was 419.86 ± 10.41 and 417.47 ± 8.25 μm, respectively (p > 0.05). Conclusions Isotonic RF-HPMC lead to a significant increase in intraoperative mean TCP. RF-HPMC seems to be a favorable riboflavin option in keratoconus patients with thin corneas.
