ABSTRACT

Pituitary metastasis (PM) is rare occurrence and accounts for <1% of all intracranial metastatic lesions. In this study, we highlight the importance of considering atypical sites for lung adenocarcinoma metastasis by presenting a case of a 54-year-old male who was diagnosed with PM 15 months after being diagnosed with stage IV lung adenocarcinoma with metastasis to the spine, pelvis, left frontal lobe, and right occipital lobe. He was on a prolonged course of chemotherapy during those 15 months and received palliative radiation for his brain metastasis with subsequent remission after 5 months following his initial diagnosis. The pituitary lesion was picked up as an incidental finding on a routine staging magnetic resonance imaging (MRI) 10 months after his brain metastasis remission. The patient successfully underwent trans-sphenoidal pituitary lesion resection. This case emphasizes the importance of routine surveillance and examination of atypical sites of metastasis even in patients undergoing a prolonged course of chemotherapy.

ABSTRACT

BACKGROUND AND OBJECTIVE: Endoscopic endonasal surgery (EES) for the management of sellar, suprasellar, and anterior skull base lesions is gaining popularity. Our aim was to analyze and present the clinical outcomes of EES for the management of these lesions in a community hospital setting. METHODS: We retrospectively reviewed the charts of 56 patients with sellar, suprasellar, and anterior skull base lesions who underwent EES between 2010 and 2018. RESULTS: There was male predominance (53.6%) with a mean age of 54.9 ± 13.7 years. Lesions were 45 pituitary adenomas, 5 meningiomas, 3 metastatic, 1 craniopharyngioma, 1 Rathke cyst, and 1 mucocele. Gross total excision was achieved in 57.1%, subtotal excision occurred in 37.5%, and decompression and biopsy were achieved in 5.4% patients. Postoperative vision normalized or improved in 27 patients (86.1%) and was stable in 4 patients (13.9%). Recovery of a preexisting hormonal deficit occurred in 13 (23.2%) patients, and a new hormonal deficit occurred in 9 patients (16.1%). The mean hospital stay was 6.1 ± 4.9 days. Postoperative complications included cerebrospinal fluid leak in 8 patients (14.3%). Four patients (7.1%) had meningitis. Diabetes insipidus was present in 19 patients (33.9%), and postoperative intracranial hematoma requiring evacuation was necessary in 2 patients (3.6%). The mean follow-up duration was 47.5 ± 25.8 months. Lesion progression or recurrence requiring redo surgery occurred in 5 patients (8.9%). Regarding the learning curve, the postoperative cerebrospinal fluid leak, meningitis, new hormonal deficits, and diabetes insipidus decreased in the second half of the patients. CONCLUSIONS: EES provides an effective and safe surgical option with low morbidity and mortality for the treatment of sellar, suprasellar, and anterior skull base lesions in a community hospital setting.

ABSTRACT

Meningiomas have long been known to be associated with sexual hormones. We discuss here the case of a woman with a huge meningioma that rapidly grew over the course of a couple years while the patient was simultaneously taking fertility treatments. There is substantial evidence suggesting that fertility treatments can fuel the growth of meningiomas. The potential risks should be considered in women with a previous or family history of meningiomas who plan to undergo fertility treatment. These patients need to be evaluated and a screening imaging of brain MRI (Magnetic Resonant Imaging) should be offered in the middle or toward the end of such a treatment to control and prevent complications of these meningiomas.

ABSTRACT

Good abdominal wall closure is one of the basic surgical skills and is a common feature of almost all modern-day CSF shunt operations. The fact that some patients require multiple abdominal operations highlights the need for a simple and effective technique for peritoneal catheter insertion through the abdominal wall and abdominal wall closure. Although technically simple, abdominal wall closure becomes more complex when combined with the requirement to maintain CSF shunt function in cases in which the shunt catheter passes through the abdominal wall into the peritoneal cavity. In this report, the authors describe a simple technique for passing the peritoneal catheter of a ventriculoperitoneal shunt through the abdominal wall on a pathway separate from the fascial opening. This technique minimizes the risk of abdominal wall-related complications and is especially important in high-risk patients such as those with obesity and/or diabetes and in children.

ABSTRACT

BACKGROUND: Midazolam and propofol are sedative agents commonly administered to patients with brain injury. We compared plasma concentrations of glial cell S100beta protein and nitric oxide (NO) between patients who received midazolam and those who received propofol sedation after severe brain injury, and investigated the association between S100beta and NO concentrations and neurological outcome. DESIGN: 28 patients with severe head injury (Glasgow Coma Score <9) who required sedation and ventilation were randomly assigned to receive midazolam (n =15) or propofol (n = 13) based sedation. Blood samples were drawn daily for 5 days for estimation of S100beta and NO concentrations. Neurological outcome was assessed 3 months later as good (Glasgow Outcome Score [GOS], 4-5) or poor (GOS, 1-3). RESULTS: A good neurological outcome was observed in 8/15 patients (53%) in the midazolam group and 7/13 patients (54%) in the propofol group. Patients with a poor outcome had higher serum S100beta concentrations on ICU admission and on Days 1-4 in the ICU than those with a good outcome (mean [SD] on Day 1, 0.99 [0.81] v 0.41 [0.4] microg/L; Day 2, 0.80 [0.81] v 0.41 [0.24] microg/L; Day 3, 0.52 [0.55] v 0.24 [0.25] microg/L; and Day 4, 0.54 [0.43] v 0.24 [0.35] microg/L; P<0.05). There was no significant difference on Day 5. Plasma NO concentrations were not associated with outcome. In subgroup analysis, there was no difference in S100beta and NO concentrations between patients with a good outcome versus those with a poor outcome in either the midazolam or propofol group. CONCLUSIONS: Plasma concentrations of markers of neurological injury in patients with severe head injury were similar in those who received midazolam sedation and those who received propofol. Patients who had a poor neurological outcome at 3 months had consistently higher serum S100beta concentrations during the initial 4 days after injury than patients who had a good outcome.

ABSTRACT

STUDY DESIGN: Psychometric evaluation of a patient-reported scale for measuring health status. OBJECTIVE: To evaluate the ability of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) to satisfy the clinical and research needs of cervical spine surgeons. SUMMARY OF BACKGROUND DATA: Although the SF-36 has been shown to be a reliable measure in the general population, the fundamental assumptions underpinning the generation of scale and summary scores must be rigorously tested before it can be considered a suitable measure for use in specific populations. METHODS: Data from 147 patients undergoing cervical spine surgery were examined. We examined the assumptions underpinning the generation of SF-36 scale and summary measures, targeting to the sample, and the scale's ability to detect change. RESULTS.: Evidence supports the reporting of SF-36 scale scores, but not SF-36 summary measures. Three of the 8 scales had notable floor/ceiling effects indicating poor targeting. Responsiveness was good for all scales except those with high floor/ceiling effects. CONCLUSIONS: The SF-36 fails to satisfy the measurement needs of cervical spine surgeons. Scale scores are valid, but floor and ceiling effects mean that changes in quality of life associated with surgery are underestimated. SF-36 summary scores are not valid. Neurosurgeons need better and more sophisticated scales to measure their outcomes.
