Abstract
RATIONALE An isolated splenic metastasis is a rare phenomenon noted in advanced stage melanoma. We report the role of radiofrequency (RF) -based splenic-preserving splenectomy in a patient with a solitary splenic metastasis from advanced stage melanoma that was managed with checkpoint inhibitors. PATIENT CONCERNS We report a case of a 60-year-old man who presented with multiple lung metastases and a solitary splenic metastasis with advanced stage melanoma following excision of primary from his trunk 2.3 years back. DIAGNOSIS Considering the diagnosis of advanced stage melanoma with multiple lung metastases and a solitary splenic metastasis, and its ongoing progressive nature. This case was discussed in the tumour board meeting. INTERVENTIONS A decision was made to commence treatment with immunotherapy in the form of PD-1 inhibitor (programmed cell death 1 receptor) pembrolizumab. Follow-up restaging computer tomography (CT) scan of the abdomen and chest showed a significant reduction in the lung and chest wall lesions, but the splenic lesion remained unchanged. Given the lack of response to treatment in the splenic metastasis and the significant decrease in lung metastases, the multidisciplinary team decided that a partial splenectomy combined with continued immunotherapy treatment would be appropriate as the success of immunotherapy was imminent within the splenic preservation. OUTCOMES The postoperative recovery was smooth and the patient was discharged from hospital on the sixth postoperative day with normal platelets and white blood cells. The histopathological analysis of the resected specimen showed a metastatic melanoma with negative margins.At 10-month follow-up after the splenic resection the patient had not experienced further tumour recurrences. LESSONS Spleen-preserving resection for an isolated, solitary splenic metastasis of melanoma is a feasible approach as it not only preserves the ongoing efficacy of checkpoint inhibitors by preserving the physiological T cell milieu, but the immunomodulation properties of RF can produce potentially additional therapeutic benefit.

Abstract
Postoperative cognitive dysfunction (POCD) increases morbidity and mortality after surgery. But the underlying mechanism is not clear yet. While age is now accepted as the top one risk factor for POCD, results from studies investigating postoperative cognitive functions in adults have been controversial, and data about the very young adult individuals are lacking. The present study investigated the spatial reference memory, IL-1β, IL-6, and microglia activation changes in the hippocampus in 2-month-old mice after anesthesia and surgery. We found that hippocampal IL-1β and IL-6 increased at 6 hours after surgery. Microglia were profoundly activated in the hippocampus 6 to 24 hours after surgery. However, no significant behavior changes were found in these mice. These results indicate that although anesthesia and surgery led to neuroinflammation, the latter was insufficient to impair the spatial reference memory of young adult mice.

Abstract
INTRODUCTION The spleen is one of the most commonly injured abdominal solid organs during blunt trauma. Modern management of splenic trauma has evolved to include non-operative therapies, including observation and angioembolization to preclude splenectomy in most cases of blunt splenic injury. Despite the shift in management strategies, relatively little is known about the hematologic changes associated with these various modalities. The aim of this study was to determine if there are significant differences in hematologic characteristics over time based on the treatment modality employed following splenic trauma. We hypothesized that alterations seen in hematologic parameters would vary between observation (OBS), embolization (EMB), and splenectomy (SPL) in the setting of splenic injury. METHODS An institutional review board-approved, retrospective study of routine hematologic indices examined data between March 2000 and December 2014 at three academic trauma centers. A convenience sample of patients with splenic trauma and admission lengths of stay >96 h was selected for inclusion, resulting in a representative sample of each sub-group (OBS, EMB, and SPL). Basic demographics and injury severity data (ISS) were abstracted. Platelet count, red blood cell (RBC) count and RBC indices, and white blood cell (WBC) count with differential were analyzed between the time of admission and a maximum of 1080 h (45 days) post-injury. Comparisons between OBS, EMB, and SPL groups were then performed using non-parametric statistical testing, with statistical significance set at p < 0.05. RESULTS Data from 130 patients (40 SPL, 40 EMB, and 50 OBS) were analyzed. The median age was 40 years, with 67 % males. Median ISS was 21.5 (21 for SPL, 19 for EMB, and 22 for OBS, p = n/s) and median Glasgow Coma Scale (GCS) was 15. Median splenic injury grade varied by interventional modality (grade 4 for SPL, 3 for EMB, and 2 for OBS, p < 0.05). Inter-group comparisons demonstrated no significant differences in RBC counts. However, mean corpuscular volume (MCV) and RBC distribution width (RDW) were elevated in the SPL and EMB groups (p < 0.01). Similarly, EMB and SPL groups had higher platelet counts than the OBS group (p < 0.01). In aggregate, WBC counts were highest following SPL, followed by EMB and OBS (p < 0.01). Similar trends were noted in neutrophil and monocyte counts (p < 0.01), but not in lymphocyte counts (p = n/s). CONCLUSION This study describes important trends and patterns among fundamental hematologic parameters following traumatic splenic injuries managed with SPL, EMB, or OBS. As expected, observed WBC counts were highest following SPL, then EMB, and finally OBS. No differences were noted in RBC count between the three groups, but RDW was significantly greater following SPL compared to EMB and OBS. We also found that MCV was highest following OBS, when compared to EMB or SPL. Finally, our data indicate that platelet counts are similarly elevated for both SPL and EMB, when compared to the OBS group. These results provide an important foundation for further research in this still relatively unexplored area.

Abstract
Human γδ T cells, which play innate and adaptive, protective as well as destructive, roles in the immune response, were discovered in 1986, but the clinical significance of alterations of the levels of these cells in the peripheral blood in human diseases has not been comprehensively reviewed. Here, we review patterns of easily measurable changes of this subset of T cells in peripheral blood from relevant publications in PubMed and their correlations with specific disease categories, specific diagnoses within disease categories, and prognostic outcomes. These collective data suggest that enumeration of γδ T cells and their subsets in the peripheral blood of patients could be a useful tool to evaluate diagnosis and prognosis in the clinical setting.

Abstract
BACKGROUND There is still considerable controversy about the importance and method of preserving splenic function after trauma. Recognition of the immune function of the spleen and the risk of overwhelming postsplenectomy infection led to the development of spleen-preserving surgery and non-operative management. More recently angiographic embolization has been used to try to reduce failure of conservative management and preserve splenic function. METHODS A literature review was performed of the changing treatment of splenic injury over the last century, focusing on whether and how to maintain splenic immune function. RESULTS Non-operative management continues to be reported as a successful approach in haemodynamically stable patients without other indications for laparotomy, achieving high success rates in both children and adults. Except for haemodynamic instability, reported predictors of failure of conservative treatment should not be seen as absolute contraindications to this approach. Angiographic embolization is generally reported to increase success rates of non-operative management, currently approaching 95 per cent. However, the optimal use of angioembolization is still debated. Splenic immunocompetence after angioembolization remains questionable, although existing studies seem to indicate preserved splenic function. CONCLUSION Non-operative management has become the treatment of choice to preserve splenic immune function. Current knowledge suggests that immunization is unnecessary after angiographic embolization for splenic injury. Identifying a diagnostic test of splenic function will be important for future studies. Most importantly, in efforts to preserve splenic function, care must be taken not to jeopardize patients at risk of bleeding who require early surgery and splenectomy.

Abstract
BACKGROUND After introducing splenic artery embolisation (SAE) in the institutional treatment protocol for splenic injury, we wanted to evaluate the effects of SAE on splenic function and assess the need for immunisation in SAE treated patients. METHODS 15 SAE patients and 14 splenectomised (SPL) patients were included and 29 healthy blood donors volunteered as controls. Clinical examination, medical history, general blood counts, immunoglobulin quantifications and flowcytometric analysis of lymphocyte phenotypes were performed. Peripheral blood smears from all patients and controls were examined for Howell-Jolly (H-J) bodies. Abdominal doppler, gray scale and contrast enhanced ultrasound (CEUS) were performed on all the SAE patients. RESULTS Leukocyte and platelet counts were elevated in both SAE and SPL individuals compared to controls. The proportion of memory B-lymphocytes did not differ significantly from controls in either group. In the SAE group total IgA, IgM and IgG levels as well as pneumococcal serotype specific IgG and IgM antibody levels did not differ from the control group. In the SPL group total IgA and IgG Pneumovax(®) (PPV23) antibody levels were significantly increased, and 5 of 12 pneumococcal serotype specific IgGs and IgMs were significantly elevated. H-J bodies were only detected in the SPL group. CEUS confirmed normal sized and well perfused spleens in all SAE patients. CONCLUSION In our study non-operative management (NOM) of high grade splenic injuries including SAE, was followed by an increase in total leukocyte and platelet counts. Normal levels of immunoglobulins and memory B cells, absence of H-J bodies and preserved splenic size and intraparenchymal blood flow suggest that SAE has only minor impact on splenic function and that immunisation probably is unnecessary.
