Careful lymph node dissection from colorectal resection specimens is important procedure for cancer staging. Present study intended to assess the impact of surgical technique and patient's obesity on this process. Number of lymph nodes harvested by manual dissection from resection specimens of 141 patients with rectal cancer and the rate of nodal metastases were analyzed and compared in different groups of patients selected by length of resection specimen and body mass index. The median and mean number of lymph nodes found per patient were 6 and 6.7. The shorter resection specimens (<16 cm after formalin fixation) yielded significantly lower number of nodes than those with length > 16 cm (5.7 versus 7.9). Most significant reduction in mean number of lymph nodes was observed in obese patients with short specimens (4.8). This subset of patients presented the lowest rate of nodal metastases (38%). The surgical technique seems to be an important factor for lymph node recovery from rectal resections specimens. The patient's obesity had an unfavourable impact on this procedure. Standardized surgery and histopathological examination are needed even in non-specialized centers to harvest adequate number of lymph nodes.

An early HCV recurrence can be expected in case of an older donor, with a marginal or fatty liver graft transplanted with a higher transfusion need and having an acute rejection treated with steroid bolus in the postoperative period. The protocol of the postoperative antiviral treatment differs from the average: the so-called "stop-rule" cannot be applied, since less then 10% of the recipients are expected to turn to HCV-PCR-negative due to the immunosuppression. The combined interferon + ribavirin treatment is maintained in spite of RNA-positive state, further, a second or third course of treatment might also be applied. The prolonged and--in case if necessary--repeated antiviral treatment prevents fibrosis, and therefore rate of retransplantation need. The better is the general state of the patient the results of a secondary liver transplantation are better as well. MELD-score can help to set the exact timing for a re-OLT.

Background Human alveolar echinococcosis (AE) caused by Echinococcus multilocularis is an underreported, often misdiagnosed and mistreated parasitic disease mainly due to its low incidence. The aim of this study was to describe the epidemiological and clinical characteristics of human AE patients in Hungary for the first time. Method Between 2003 and 2018, epidemiological and clinical data of suspected AE patients were collected retrospectively from health database management systems. Results This case series included a total of 16 AE patients. The mean age of patients was 53 years (range: 24–78 years). The sex ratio was 1:1. Four patients (25%) revealed no recurrence after radical surgery and adjuvant albendazole (ABZ) therapy. For five patients (31.3%) with unresectable lesions, a stabilization of lesions with ABZ treatment was achieved. In seven patients (43.8%), progression of AE was documented. The mean diagnostic delay was 33 months (range: 1–122 months). Three AE related deaths (fatality rate 18.8%) were recorded. Conclusions AE is an emerging infectious disease in Hungary with a high fatality rate since based on our results, almost every fifth AE patient died in the study period. Differential diagnosis and appropriate surgical and medical therapy for AE is an urging challenge for clinicians in Hungary, as well as in some other European countries where E. multilocularis is prevalent.
