Electrocution injuries, particularly high voltage, are uncommon, but can be devastating. Thermal burns, arrhythmias and myonecrosis are commonly known and monitored complications of electrical injuries. Direct thermal trauma to internal viscera is also known and almost all internal organs have been reported to be affected, bowel being the most common. However, bowel perforation occurring in a delayed fashion is one rare, dreaded and erratic complication of electrocution, making it a dangerous pitfall if missed. Alimentary tract perforations can present on a delayed basis in high voltage electrocution injuries; advise for clinical follow up must incorporate this possibility at the time of discharge. Presentation of delayed visceral injuries is subtle & atypical, and post burn immunosuppression may play a part for such presentation. We suggest that all victims of high voltage electrocution with abdominal wall burns receive diagnostic laparoscopy and/or CECT abdomen as part of workup of their injuries. Any non-enhancing segment of bowel on CECT, howsoever small, should be prudently evaluated with laparoscopy.
Microvascular reconstructions after head and neck cancer are among the most complicated procedures in plastic surgery. Postoperative complications are common, which often leads to prolonged hospital stay. Enhanced recovery after surgery (ERAS) is a peri- and postoperative care concept with the aim of achieving pain- and risk-free surgery. It has been previously established as superior to conventional care for a wide variety of procedures, including microsurgical procedures such as reconstructions of the breast. Several ERAS protocols for microvascular head and neck cancer reconstructions have been proposed, although most of these are based on extrapolated evidence from different surgical specialties. Results from the implementation of ERAS for these procedures are inconsistent.

The current study investigates our clinical experience of head and neck cancer reconstruction for the period of 2014-2016 with the aim of establishing a list of functional discharge criteria. By combining these with the current published knowledge on the subject, we developed an ERAS protocol.

We performed 89 microvascular procedures in the study period, of which 58 were in the oral cavity/sinuses and 31 were laryngopharyngeal. Most cases were squamous cell carcinoma (89%). The average LOS was 20.3 days in both groups. Postoperative complications included infection (37%), 30-days re-operations (19%), and re-admissions (17%). Furthermore, we identified the following discharge criteria adequate pain relief, ambulation, sufficient nutritional intake, normal infection-related blood parameter results and absence of fever, bowel function, and closure of tracheostomy.

Based on our retrospective analysis and identified discharge criteria, we present an approach to develop an ERAS protocol for microvascular reconstruction after head and neck cancer.

In this study, we present a retrospective study of 133 hospitalized confirmed mild coronavirus disease 2019 (COVID-19) cases, including 116 patients with COVID-19 with negative serum hepatitis B antigen and 17 HBV inactive carriers with COVID-19. We found that there were no significant differences for the discharge rate or duration of hospitalization between the two groups. click here However, inactive HBV carriers with SARS-CoV-2 co-infection are at a higher risk of abnormal liver function tests. The enhanced liver injury induced by SARS-CoV-2 and HBV co-infection was identified as the hepatocyte type rather than the cholangiocyte type. Moreover, the inflammatory response, including abnormal lactate dehydrogenase, D-dimer and interleukin-6 production, may contribute to this injury following SARS-CoV-2 co-infection. Collectively, SARS-CoV-2 and HBV co-infection exacerbates liver function of the patients with COVID-19.We report 2 cases of ipsilateral ankle and knee osteoarthritis (OA), with the chief complaint being chronic ankle and knee pain. In the first patient, the ankle pain was more severe than the knee pain, whereas the second patient had more severe pain in the knee than in the ankle. In both cases, varus malalignment of the knee and varus tilt of the ankle joint were detected on standing radiographs. The severity of OA was found to be grade 4 in the knee, according to the Kellgren-Lawrence grading system, and stage IIIa in the ankle, according to the modified Takakura ankle OA classification system. Navigation-assisted total knee arthroplasty was performed in both cases, leading to a decreased degree of varus malalignment in the knee and ankle, as well as a significantly improved patient-based outcome in both joints. Correction of malalignment of the ankle by total knee arthroplasty relieved the severe pain and restored optimal function in the ankle without surgical intervention.Respiratory syncytial virus (RSV) is the primary cause for acute lower respiratory syndrome in children younger than 5 years. Research on B cell repertoires and antibodies binding the RSV fusion protein (RSV F) is of major interest in the development of potential vaccine candidates and therapies. B cell receptors (BCRs) which have higher affinities for a specific antigen are preferentially selected for B cell clonal expansion in germinal center reactions. Consequently, antigen-specific BCR repertoires share common features, as for instance preferential variable gene usage, variable region mutation levels or lengths of the heavy chain complementarity-determining region 3. Since RSV repeatedly infects every person throughout life, memory B cells (MBC) expressing RSV F-binding BCRs circulate in the blood of healthy adults. This dataset of BCR variable region sequence features was derived from single cell-sorted RSV F-directed MBCs of a healthy adult blood donor [1]. The dataset was produced with publicly available data analysis software programs and scripts, which facilitates integration or comparison with antibody sequence repertoire data of different individuals derived with the same or comparable data analysis approaches and tools.
