On the shoulders of giants: Harvey Cushing's experience with acromegaly and gigantism at the Johns Hopkins Hospital, 1896-1912

The Internal Cranial Anatomy of a Female With Endocrine Disorders From a Mediaeval Population

Gigantism and acromegaly have been observed in past populations; however, analyses usually focus on the morphological features of the post-cranial skeleton. The aim of this study is to characterize the internal anatomical features of the skull (brain endocast anatomy and asymmetry, frontal pneumatization, cranial thickness, sella turcica size) of an adult individual from the 11-14th centuries with these two diseases, in comparison with non-pathological individuals from the same population. The material consisted of 33 adult skulls from a mediaeval population, one of them belonging to an adult female with endocrine disorders (OL-23/77). Based on the CT scans, the internal cranial anatomy was analysed. The sella turcica of OL-23/77 is much larger than in the comparative sample. The endocast of the individual OL-23/77 shows a left frontal/left occipital petalia, while the comparative population mostly had right frontal/left occipital petalias. The asymmetry in petalia location in OL-23/77 comes within the range of variation observed in the comparative population. The individual has high values for cranial thickness. The frontal sinuses of the specimen analysed are similar in size and shape to the comparative sample only for data scaled to the skull length. Enlarged sella turcica is typical for individuals with acromegaly/gigantism. The pattern of the left frontal/left occipital petalia in the specimen OL-23/77 is quite rare. The position of the endocranial petalias has not influenced the degree of asymmetry in the specimen. Despite the large bone thickness values, skull of OL-23/77 does not show any abnormal features. The skull/endocast relationship in this individual shows some peculiarities in relation to its large size, while other internal anatomical features are within the normal range of variation of the comparative sample.

Access to the Skull Base - Maxillary Swing Procedure - Long Term Analysis

Background:

Skull base is difficult to approach surgically due to its complex anatomy. A number of procedures that is endoscopic, microscopic, and open approaches have been used. The maxillary swing approach provides a wide exposure to the surgeon for better oncological clearance.

Patients and Methods:

A total of 62 patients with varied etiologies involving the skull base region were operated with maxillary swing procedure over a period of 15 years from 2001 to 2016 in plastic surgery department at a single institution.

Results:

There was no recurrence in the follow-up period. One patient had palatal fistula and one patient had mild nasal mucosal atrophy. None of the patients had malocclusion in the postoperative period. The minimum follow-up period was 24 months.

Conclusion:

Maxillary swing procedure provides excellent exposure to skull base, and most of the tumors involving this region can be effectively excised with minimal morbidity to the patient.

Walter E. Dandy: his contributions to pituitary surgery in the context of the overall Johns Hopkins Hospital experience

BACKGROUND

Walter E. Dandy (1886-1946) was an outstanding neurosurgeon who spent his entire career at the Johns Hopkins Hospital. After graduating from medical school in 1910, he completed a research fellowship in the Hunterian laboratory with Harvey Cushing and then joined the Department of Surgery as resident, rising to the rank professor in 1931. Dandy made several contributions that helped building the neurosurgical specialty, most famously the introduction of pneumo-ventriculography to image brain lesions for which he received a Nobel prize nomination. He also performed many pituitary surgeries, although his role in this area is less known and overshadowed by that of Cushing's.

PURPOSE

This retrospective cohort study was designed to unveil Dandy's pituitary work and place it in the context of the overall pituitary surgeries performed at the Johns Hopkins Hospital.

METHODS

Pituitary surgery data were obtained by screening the paper and electronic surgical pathology records of the Department of Pathology, as well as the general operating room log books of the Johns Hopkins Hospital housed in the Chesney Medical Archives.

RESULTS

A total of 3211 pituitary surgeries associated with a pathological specimen were performed between February 1902 and July 2017 in 2847 patients. Most of the surgeries (2875 of 3211 89%) were done by 21 neurosurgeons. Dandy ranks 4th as number of surgeries, with 287 pituitary operations in 35 years of activity. He averaged 8 pituitary surgeries per year, a rate that positions him 6th among all Hopkins neurosurgeons. With the exception of his first operation done in July 1912 while Cushing was still at Hopkins, Dandy approached the pituitary gland transcranially, rather than transphenoidally. The majority of Dandy's pituitary patients had a pathological diagnosis of pituitary adenomas, followed by craniopharyngiomas and sellar cysts. In the decades Dandy operated, pituitary surgeries represented 0.56% of the total Johns Hopkins surgeries, a percentage significantly greater (p < 0.001) than the 0.1% observed in modern days. Dandy's pituitary clinical work was matched by important experimental studies done in the early stages of his career.

CONCLUSIONS

This study highlights the role of Dandy as an important contributor to advance our understanding of pathophysiology and treatment of pituitary diseases.

The pursuit of a cholesteatoma by harvey cushing: staged approach to a complex skull base tumor

Objective The evolution of neurosurgical techniques during Harvey Cushing's practice was immense. The authors illustrate this evolution using archived historical records from Harvey Cushing. Setting Historical patient records retained by the Cushing Center at Yale University Department of Neurosurgery. Design The authors present the case of one of Cushing's patients with a cholesteatoma. Results Cushing's surgical treatment of a cholesteatoma extending into the skull base is an example of his meticulous documentation and accelerated surgical techniques. Conclusions This case demonstrates how neurosurgical techniques advanced in the management of complex skull base tumors via a staged approach through the middle and posterior fossae at a time long before the development of modern skull base surgery.

Transfacial approaches to the skull base: the early contributions of harvey cushing

In this report, we review Dr. Cushing's early surgical cases at the Johns Hopkins Hospital, revealing details of his early use of craniofacial approaches for malignant pathology of the skull base. Following Institutional Review Board approval, and through the courtesy of the Alan Mason Chesney Archives, we reviewed the Johns Hopkins Hospital surgical files from 1896 to 1912, which included three patients who underwent surgical treatment of lesions involving the skull base through craniofacial approaches: two adults and one child (range 3 to 43 years). The main outcome measures were length of stay and condition recorded at the time of discharge. The indications for surgery included osteochondroma of the sphenoid sinus, sarcoma of the maxillary sinus and middle fossa, and osteoma of the frontal sinus. The mean length of stay was 24.5 days (range 7 to 45 days). Cushing employed craniofacial approaches for malignant pathology nearly 40 years before such techniques became widely used. He practiced the fundamentals of skull base surgery, including preferential removal of bone to achieving adequate exposure for resection. In addition, Cushing clearly understood the importance of proximal vascular control in approaching lesions with complex vascular involvement.

Sellar door: Harvey Cushing's entry into the pituitary gland, the unabridged Johns Hopkins experience 1896-1912

OBJECTIVE

To review the original surgical records from the Johns Hopkins Hospital, and analyze the records of patients Cushing treated for pituitary disorders from 1896 to 1912.

METHODS

Following IRB approval, and through the courtesy of the Alan Mason Chesney Archives, we reviewed the original surgical files from the Johns Hopkins Hospital. Patients presenting with pituitary-related symptoms, who underwent surgical treatment directed at the pituitary gland, were selected for further review.

RESULTS

Thirty-seven patients who underwent surgical intervention for pituitary disorders were found. Of these patients, 12 were mentioned only briefly in Cushing's 1912 monograph, whereas 6 were not described at all. The remaining 19 were documented by Cushing in his 1912 monograph. Cushing used three main surgical approaches to the pituitary: transsphenoidal, transcranial, and the subfrontal "omega incision." There were 6 inpatient deaths. The mean time to last follow-up was 41.0 months. At follow-up, headache was the most common unresolved symptom.

CONCLUSION

This review highlights Cushing's accomplishments in the surgical treatment of suspected pituitary pathology during his early career as a young attending at Johns Hopkins Hospital. It reveals new information about patients whom Cushing did not include in his publications detailing his surgical experience at the Johns Hopkins Hospital.

Harvey Cushing's Approaches to Tumors in His Early Career: From the Skull Base to the Cranial Vault

In this report, we review Dr. Cushing's early surgical cases at the Johns Hopkins Hospital, revealing details of his early operative approaches to tumors of the skull base and cranial vault. Following Institutional Review Board approval, and through the courtesy of the Alan Mason Chesney Archives, we reviewed the Johns Hopkins Hospital surgical files from 1896 to 1912. Participants included four adult patients and one child who underwent surgical resection of bony tumors of the skull base and the cranial vault. The main outcome measures were operative approach and condition recorded at the time of discharge. The indications for surgery included unspecified malignant tumor of the basal meninges and temporal bone, basal cell carcinoma, osteoma of the posterior skull base, and osteomas of the frontal and parietofrontal cranial vault. While Cushing's experience with selected skull base pathology has been previously reported, the breadth of his contributions to operative approaches to the skull base has been neglected.
