Background: Hepatic arterial anomalies (HAAs) are not infrequently encountered during pancreatic resections. In view of the current emergence of the robotic platform as a safe alternative to open surgery in experienced centres, this study sought to determine the implications of HAAs on the safety and oncologic outcomes of robotic pancreaticoduodenectomy (RPD).
Methods: A prospectively maintained database of patients with HAAs who underwent RPD (RPD + HAA) at a single institution between 2008 and 2013 was retrospectively reviewed. Demographic information and perioperative outcomes of RPD were compared for patients with and without HAAs.
Results: A total of 142 patients underwent RPD; 112 (78.9%) did not have and 30 (21.1%) did have HAAs. The majority (90.0%) of RPDs in patients with HAAs were performed for malignant indications and all aberrant vessels were preserved without conversion to laparotomy. There were no statistically significant differences between RPD patients with and without HAAs with respect to preoperative demographics, tumour characteristics, operative metrics (operative time, estimated blood loss, conversion) and postoperative outcomes, including complications, length of stay and readmissions. Negative margin (R0) rates were similar in both groups.
Conclusions: Robot-assisted pancreaticoduodenectomy is safe and feasible in patients with HAAs and has outcomes similar to those in patients with normal arterial anatomy.

Bacterial meningitis is an increasingly rare disease that carries significant morbidity and mortality. We describe the case of a 38-year-old male with a past medical history of pituitary macroadenoma with prior endonasal surgeries on prednisone therapy daily for resultant hypopituitarism and juvenile myoclonic epilepsy on lamotrigine daily who was transferred to an academic tertiary emergency department due to concern for developing pituitary apoplexy. At the outside emergency department, the patient presented complaining of sudden onset severe headache.

Neoadjuvant systemic treatment strategies have improved outcomes in several solid tumour types. This success has not yet been replicated in renal cell carcinoma (RCC). A consensus and international collaboration are urgently needed for the development of adaptive perioperative immunotherapy strategies for patients with RCC at high risk of recurrence.

Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

Objectives: Patient experience surveys are essential to measuring patient-centered care, a key component of health care quality. Low response rates in underserved groups may limit their representation in overall measure performance and hamper efforts to assess health equity. Telephone follow-up improves response rates in many health care settings, yet little recent work has examined this for surveys of Medicare enrollees, including those with Medicare Advantage.

The number of patients with invasive home mechanical ventilation (IHMV) in Germany is vastly increasing. Currently, only limited data is available on the characteristics of these patients. The aim of the present study was to describe the health care situation of IHMV patients living in Bavaria using routinely collected data within the project OVER BEAS.
