Introduction Anorectal melanoma (ARM) is a rare and aggressive neoplasm with predisposition for early infiltration, distant spread, and unfavorable prognosis. It has been speculated that Malassezia yeasts could possibly have an impact on skin carcinogenesis and development of melanoma, especially in patients with seborrheic dermatitis (SD), due to production of aryl hydrocarbon receptor (AhR) agonists. Case Outline A 52-year-old man with intensive SD complained of a four-month-long rectal bleeding, tenesmus, pain, and difficulty during defecation. On examination, a rectal tumor was detected and histopathology of tumor tissue revealed ARM with positive protein S100, melanoma antigen HMB45 and melan-A expression. After the diagnosis was established, abdominoperineal resection of the anus and rectum was performed, since the tumor was large, obstructive, and the anal sphincter was invaded. Conclusion Because of the possible impact of intensive SD to the cross-link between Malassezia yeasts AhR agonists and skin carcinogenesis, we discussed on this matter and reviewed the literature data regarding ARM. In addition to “pathogenic” and “non-pathogenic” Malassezia subtypes based on AhR agonist production, future studies on Malassezia metabolites, their carcinogenic effect in the skin and development of melanoma are needed. If the cross-link between Malassezia AhR agonists and skin carcinogenesis exists, timely prevention of ARM could be done with Malassezia eradication, especially in patients with severe SD. © 2016.

Objectives: Many countries around the world have recognized the need for using an electronic health record (EHR) system. However, there is limited literature that could serve as a guide during a lengthy and challenging process of planning, development, and implementation of the e-Health system. Since the EHR system was recently introduced in Serbia, the purpose of this communication is to describe our experience and lessons learned along the way. Methods: The key personnel involved in the implementation of the EHR system in Serbia that began in 2015 conducted in 2019 a retrospective narrative review of the process and early outcomes. Results: An incremental approach in the planning, development, and implementation of the nationwide EHR system was taken. The process was split into phases with the gradual introduction of different regions of the country. The gradual shift from the existing to a new workflow for the prospective users was also implemented. The significant milestones were the achievement of quick legislative changes, the hiring of a professional team of experts in the field, the provision of timely and appropriate information and training to prospective users, the close collaboration between the implementation team and the Ministry of Health and mutual understanding of the aims and expectations, and the flexibility in accepting the evolving nature of the process, goals, and the system model. Conclusions: A successful implementation of the nationwide EHR system is feasible providing careful planning, the assembly of a multi-disciplinary team, the use of a stepwise approach, the early and continued involvement of the intended users, and the willingness to make adjustments along the way. The end-result sets the stage for the reform of the health care system itself. © 2022, Dr. Mladen Stojanovic University Hospital. All rights reserved.

Introduction Infection of synthetic graft in the groin is a rare but devastating complication. When it occurs, several possibilities of treatment are available. Extra-anatomic reconstruction and in-situ implantation of new, infection resistant grafts are associated with high mortality and morbidity. Therefore, more conservative approach is needed in some cases. Negative-pressure wound therapy is one of the options in treating such patients. Objective The aim of this study was to assess the outcome for deep groin vascular graft infection treated with negative-pressure wound therapy. Methods Seventeen patients (19 wounds), treated for Szilagyi grade III groin infections between October 2011 and June 2014, were enrolled into this observational study. Results Majority of the wounds (11/19) were healed by secondary intention, and the rest of the wounds (8/19) were healed by primary intention after initial negative-pressure wound therapy and graft substitution with silver-coated prostheses or autologous artery/vein implantation. No early mortality was observed. Minor bleeding was observed in one patient. Reinfection was noted in three wounds. Only one graft occlusion was noted. Late mortality was observed in three patients. Conclusion Negative-pressure wound therapy seems to be safe for groin vascular graft infections and comfortable for both patient and surgeon. However, the rate of persistent infection is high. This technique, in our opinion, can be used as a “bridge” from initial wound debridement to definitive wound management, when good local conditions are achieved for graft substitution, either with new synthetic graft with antimicrobial properties or autologous artery/vein. In selected cases of deep groin infections it can be used as the only therapeutic approach in wound treatment. ©2016, Serbia Medical Society. All rights reserved.

Background/Aim. The incidence of nodular thyroid disease increases significantly with age as well as the incidence and aggressiveness of thyroid cancers. The aim of the study was to determine whether thyroid surgery for geriatric patients is safe in a short hospital stay surgery setting. Methods. In this retrospective study, medical histories of all operated geriatric patients (65 years and older), in whom a total thyroidectomy (TT) or hemithyroidectomy (HT) was performed from January 2012 to December 2018, were analyzed. A total of 976 patients were operated on for thyroid diseases in the mentioned period, out of which 247 geriatric patients fulfilled the inclusion criteria. Patients with thyroid reoperations and simultaneous neck lymph node dissections were excluded from the study. The geriatric patients were divided into two groups: the HT group (33 patients) and the TT group (214 patients). Each of these two geriatric groups, HT and TT, had two additional paired control groups. Control group I consisted of younger subjects from 20–44 years, and control group II included middle-aged subjects from 45–64 years. Results. All three TT groups – geriatric, control I, and control II, had 214 patients each, and all three HT groups had 33 patients each. In all three HT groups, the average hospital stay was 24 hrs, while in the TT geriatric group, 150 (70.1%) of 214 patients spent 24 hrs at the hospital. In the geriatric population, the incidence of neck swelling and increased drainage output were higher compared to both control groups, and thus the need for longer hospitalizations. When the age was compared, it was shown that subjects with each subsequent year of intervention had a 22% lower chance of developing complications, and regarding the pathohistological finding, benign thyroid hyperplasia was less likely to develop complications compared to malignant hyperplasia. Conclusion. According to the study, TT can be safely performed within the concept of a short hospital stay in patients under 65 years, while in the elderly, hospitalization days may be extended due to more frequent surgical and nonsurgical complications. Speaking of HT, the short hospital stay is safe for all age groups. © 2023 Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.
