Is the social status a new prognostic factor in the Fournier's gangrene?

Fournier's gangrene is a life-threatening acute necrotizing fasciitis of perianal, genitourinary and perineal areas. Local symptoms are scrotal swelling, erythema of scrotal skin and pain with generalized constitutional symptoms. The gangrene may extends to abdominal wall, intra-abdominal structures, and even in the retroperitoneal tissues. Urgent surgical debridement is crucial to warrant a good outcome since delayed intervention carries a poor prognosis. We report the case of a not diabetic patient with Fournier's disease presented with severe sepsis and successfully treated with urgent deep debridement and reconstructive surgery. We propose the social status of the patient as a prognostic factor with high impact for survival rate.

Adenomyoepithelioma of the breast: case report and literature review.

Adenomyoepithelioma are uncommon tumors. The majority of them occur in women in the fifth and sixth decades who usually present with a self-palpated, solitary breast mass or a lesion identified on mammography. We report the case of adenomyoepithelioma of the breast with malignant transformation of both myoepitheliel and epithelial components diagnosed as malignancy during the preoperative stage in a seventy-six year old woman.

Different characteristics of circular staplers make the difference in anastomotic tensile strength.

Anastomotic leak after gastrointestinal surgery is a severe complication associated with relevant short and long-term sequelae. Most of the anastomoses are currently performed with a surgical stapler that is required to have appropriate characteristics in order to guarantee good performances. The aim of our study was to evaluate, ex vivo, pressure resistance and tensile strength of anastomosis performed with different circular staplers available in the market. We studied 7 circular staplers of 3 different companies, 3 of them used for gastrointestinal anastomosis and 4 staplers for hemorrhoidal prolapse excision. A total of 350 anastomoses, 50 for each of the 7 staplers, were performed using healthy pig fresh intestine, then injected saline solution and recorded the leaking pressure. There were no statistically significant differences between the mean pressure necessary to induce an anastomotic leak in the various instruments (p>0.05). For studying tensile strength, we performed a total of 350 anastomoses with 7 different circular staplers on a special strong paper (Tyvek), and then recorded the maximal tensile force that could open the anastomosis. There were statistically significant differences between one brand stapler vs other 2 companies staplers about the strength necessary to open the staple line (p<0.05). In conclusion, we demonstrated that different circular staplers of three companies available in the market give comparable anastomotic pressure resistance but different tensile strengths. This is probably due to different technical characteristics.

Procalcitonin, as an early biomarker of colorectal anastomotic leak, facilitates enhanced recovery after surgery.

PURPOSE: Procalcitonin (PCT) is a biomarker used to help sepsis diagnosing and monitoring and guide antibiotic therapy. Anastomotic leak (AL) after colorectal surgery is a severe complication associated with relevant short- and long-term sequelae. The aim of our study is to assess the predictive value of PCT levels to early diagnose AL after colorectal surgery. METHODS: Between September 2011 and September 2012, a series of 99 patients underwent colorectal surgery in our institution. In all cases, white blood cell (WBC) count, C-reactive protein (CRP), and PCT levels were measured in first, third, and fifth postoperative day (POD). Anastomotic leaks and all other postoperative complications were recorded. RESULTS: We registered 7 ALs (7.1%). Decreased PCT levels had a significant negative predictive value (NPV) for AL in third and fifth POD (96.7% and 96.7%, respectively), compared with CRP and WBC. The best diagnostic performance was obtained with the combination of PCT and CRP measurements in third and fifth POD (area under the curve, 0.87 and 0.94, respectively). In 5th POD, PCT improves diagnosis, but not in a statistically significant way (area under the curve, 0.86). CONCLUSIONS: Compared with more established biochemical values such as CRP and WBC, PCT is an earlier, more sensitive, and reliable marker of AL. Increased PCT levels in early PODs after colorectal surgery may provide a more effective way to detect AL, before clinical symptoms appear. Moreover, normal PCT values might be also a useful marker to facilitate a safe and early discharge of selected patients after colorectal surgery.
