Anton de Haen (1704-1776) and his extraordinary "portentosum infundibulum" case: the futile skull cauterization of a blind patient with a craniopharyngioma.
Anton de Haen (1704-1776) became one of the most influential physicians in the Habsburg Empire as a reformer of clinical instruction at Vienna Citizen's Hospital (Bürgerspital), where he introduced the bedside teaching method he had learned from Herman Boerhaave in Leyden, Holland. He also promoted the meticulous recording of clinical observations and the use of postmortem studies to identify the cause of death in hospitalized patients. Among the numerous clinicopathological reports compiled in his monumental 18-volume work Rationis Medendi in Nosocomio Practico, published in 1761, was the first documented patient with amenorrhea caused by a pituitary tumor, appearing in the 6th volume. ⋯ At the autopsy, a large solid-cystic and calcified tumor with gross characteristics typical of adamantinomatous craniopharyngioma was found encroaching on the infundibulum and third ventricle. This is the first known account of an infundibulo-tuberal lesion associated with the impairment of sexual functions, predating by 140 years the pathological evidence for a sexual brain center sited at the basal hypothalamus. In this paper, the authors analyze the historical importance and impact of de Haen's foundational report on the fields of neuroendocrinology and neurosurgery.

Effect of shorter nerve graft and selective motor branch of recipient nerve on nerve transfer surgery for elbow flexion in patients with brachial plexus injury.
The spinal accessory nerve (SAN) is commonly used as a donor nerve for reinnervation of elbow flexors in brachial plexus injury (BPI) reconstruction. However, no study has compared the postoperative outcomes between SAN-to-musculocutaneous nerve (MCN) transfer and SAN-to-nerve to biceps (NTB) transfer. Thus, this study aimed to compare the postoperative time to recovery of elbow flexors between the two groups. ⋯ SAN-to-NTB transfer in combination with the proximal dissection technique is the preferred nerve transfer option for restoration of elbow flexion in traumatic pan-plexus palsy.

The influence of tumor topography on the surgical outcome of craniopharyngiomas.
Various topographical classifications for craniopharyngioma have been proposed based on their relationship with optic chiasm and the third ventricular floor. There is a paucity of literature evaluating the surgical outcome based on tumor topography. This study aims to compare the surgical outcomes of retrochiasmatic craniopharyngiomas (RCPs) and nonretrochiasmatic craniopharyngiomas (non-RCPs). ⋯ The tumor topography can influence the postoperative outcome. RCPs can be associated with a higher incidence of hypopituitarism and hypothalamic morbidities postoperatively. The influence of topography on EOR and tumor recurrence is controversial. However, this study did not find a significant difference in EOR and tumor recurrence between RCPs and non-RCPs. PFS and overall mortality are also comparable.

Cost-effectiveness of postoperative imaging surveillance strategies for nonfunctional pituitary adenomas after resection with curative intent.
The aim of this study was to determine an optimal follow-up imaging surveillance strategy in terms of cost-effectiveness after resection of nonfunctioning pituitary adenomas with curative intent. ⋯ Using standard cost-effectiveness thresholds in the US ($100,000/QALY), personalized surveillance that accounted for remnant disease or postoperative changes on MRI was cost-effective compared with alternative surveillance strategies.
