Long-term outcomes following maximal safe resection in a contemporary series of childhood craniopharyngiomas.

BACKGROUND: The optimal management of pediatric craniopharyngiomas remains controversial. This study aimed to characterize long-term outcomes in a contemporary cohort of children undergoing surgery for craniopharyngiomas. METHODS: This was a retrospective review of 37 consecutive children who underwent surgery for craniopharyngioma with a median follow-up duration of 79 months (range 5-127 months). Patients were stratified by extent of resection (EOR) and need for adjuvant radiation therapy (RT). Imaging studies were reviewed to grade extent of hypothalamic involvement. Data on functional outcomes, pituitary function, and obesity were analyzed. RESULTS: Gross total resection was achieved in 16 patients (43.2%), near total resection in six patients (16.2%), and subtotal resection (STR) in 15 patients (40.5%). The recurrence-free survival rate was 81.1% and 70.3% at 5- and 10-year follow-up, respectively. Survival analysis showed superior disease control in patients undergoing STR + RT (p = 0.008). Functional outcomes were independent of EOR, postoperative RT or recurrence. Diabetes insipidus was present in 75% and 44.4% of patients required >2 hormone replacements at last follow-up. Obesity was present in 36.1% patients after treatment, and was associated with preoperative obesity (p = 0.019), preoperative hypothalamic involvement (p = 0.047) and STR + RT (p = 0.011). CONCLUSIONS: Gross or near total resection may be achieved safely in almost 60% of cases; however, radical surgery does not eliminate the risk of recurrence. Over long-term follow-up, STR + RT offers the best disease control rates. Patients with preoperative hypothalamic involvement, obesity, and those with tumors not amenable to radical resection are at risk for developing obesity on long-term follow-up.

Insulin Use, Diabetes Control, and Outcomes in Patients with COVID-19.

Background: The novel coronavirus (SARS CoV-2) has caused significant morbidity and mortality in patients with diabetes. However, the effects of diabetes control including insulin use remain uncertain in terms of clinical outcomes of patients with COVID-19.Methods: In this single-center, retrospective observational study, all adult patients admitted to Einstein Medical Center, Philadelphia, from March 1 through April 24, 2020 with a diagnosis of COVID-19 and diabetes were included. Demographic, clinical and laboratory data, insulin dose at home and at the hospital, other anti-hyperglycemic agents use, and outcomes were obtained. Multivariate logistic regression was used to evaluate the factors associated with diabetes control and mortality.Results: Patients who used insulin at home had higher mortality compared to those who did not (35% vs 18% p = .015), this was true even after adjustment for demographics, comorbidities and a1c OR 2.65 95% CI (1.23-5.71) p = .013. However, the mean a1c and the median home requirements of insulin did not significantly differ among patients who died compared to the ones that survived. Patients who died had significantly higher inpatient insulin requirements (highest day insulin requirement recorded in units during hospitalization) 36 (11-86) vs 21 (8-52) p = .043 despite similar baseline a1c and steroid doses received. After adjusting for demographics, comorbidities and a1c, peak insulin requirements remained significantly associated with inpatient mortality OR 1.022 95% CI (1.00-1.04) p = .044.Conclusion: Among diabetic patients infected with COVID-19, insulin therapy at home was significantly independently associated with increased mortality. Peak daily inpatient insulin requirements was also independently associated with increased inpatient mortality.

Selective perioperative steroid supplementation protocol in patients undergoing endoscopic transsphenoidal surgery for pituitary adenomas.

BACKGROUND: There is no consensus regarding the use of perioperative steroids for transsphenoidal pituitary surgery. We audited the effectiveness and safety of our selective perioperative steroid supplementation protocol in patients with pituitary adenomas. METHODS: Two hundred ninety-seven patients underwent 306 endoscopic transsphenoidal surgeries for removal of their pituitary tumors. Steroids were given to those with an impaired hypothalamic-pituitary-adrenal (HPA) axis, age ≥ 60 years, clinical apoplexy, hyponatremia, or if the pituitary gland was not preserved at surgery. We excluded 111 patients in whom the integrity of the HPA axis could not be determined. We compared the incidence of early postoperative adrenal insufficiency and complications in 135 patients with intact HPA axes who underwent surgery without steroids (group A) with 60 patients who had compromised preoperative HPA axes and received perioperative steroids (group B). In addition, we audited the total number of protocol violations during this period. RESULTS: Five patients (3.7%) in group A developed postoperative hypocortisolemia. There was no significant difference in the incidence of cerebrospinal fluid leak, diabetes insipidus, or hyponatremia between both groups. There were protocol deviations in 47 (15.4%) patients. Twenty one of these patients did not receive perioperative steroids in violation of the protocol, of whom 4 (19%) developed postoperative hypocortisolemia. CONCLUSIONS: Our steroid sparing protocol was both safe and effective. The 15% incidence of protocol deviations is a reminder that the rigorous usage of checklists is mandatory for successful clinical practice.

A 62-Year-Old Immunocompromised Man With Halo Sign on Chest Imaging.

CASE PRESENTATION: A 62-year-old White man with a history of orthotopic liver transplantation 16 years ago for alcoholic liver cirrhosis on chronic immunosuppression and recurrent decompensated cirrhosis of his graft liver complicated by ascites, hepatic encephalopathy, and esophageal varices presented to the hospital with altered mental status. Over the last few weeks, he had reduced frequency of bowel movements and subsequently developed altered sensorium 3 days before presentation. On arrival to the hospital, he was disoriented and had asterixis consistent with hepatic encephalopathy. He was not in respiratory distress, he was saturating well on room air, and his lungs were clear to auscultation bilaterally. Plain chest radiograph showed multiple ill-defined bilateral airspace opacities. A CT scan of the abdomen and pelvis done on admission incidentally showed bilateral pulmonary nodules with surrounding ground-glass halo in the lower lung zones. Given these findings, a dedicated CT scan of his chest was performed that showed numerous bilateral randomly distributed nodular airspace opacities, many with a central solid component and surrounding ground-glass halo. Antifungal therapy was initiated empirically. Serum aspergillus antigen and 1,3 beta D-glucan were negative. He subsequently underwent a bronchoscopy with BAL and transbronchial biopsy. BAL fluid was negative for bacterial, fungal, and acid-fast bacilli cultures. Pathology from the transbronchial biopsy showed atypical epithelioid cells in intravascular spaces.

Impact of achieving euthyroidism on pulmonary artery systolic pressures in hyperthyroidism-associated pulmonary hypertension - a systematic review.

In this systematic review, we seek to clarify the impact of treatment of hyperthyroidism on pulmonary hypertension in patients with both these conditions. We included 39 of 709 articles retrieved, that studied patients with hyperthyroidism and pulmonary hypertension (PH). From these, those with a documented pre-treatment Pulmonary Artery Systolic Pressure (PASP) > 35 mmHg and complete follow up were analyzed, yielding 3 case series and 22 case reports with a total of 81 cases. A significant improvement in PASP was noted with achieving euthyroidism in the 3 case series. The case reports showed a significant reduction in mean PASP from 60.5 ± 13.2 mmHg to 37.5 ± 10.1 mmHg (p < 0.001) in patients with Grave's disease with achieving euthyroidism. No deaths were reported during the follow up period. Achievement of a euthyroid state in patients with hyperthyroidism is associated with statistically significant reductions in PASP.

A Comparison of Long-Term Treatment Outcomes Between Giant and Nongiant Craniopharyngiomas.

BACKGROUND: There is limited literature on outcomes after surgical treatment of giant craniopharyngiomas in adult and pediatric patients. METHODS: A retrospective review of 159 patients undergoing surgery for craniopharyngiomas at a single institution was performed. Patients with giant craniopharyngiomas (maximum dimension ≥4.5 cm) were compared with nongiant tumors in terms of various clinical and radiological parameters and long-term surgical outcomes. Extent of resection was determined by postoperative magnetic resonance imaging. Factors associated with post-treatment obesity were also analyzed. RESULTS: Giant craniopharyngiomas (n = 66) were characterized by higher rates of childhood presentation, visual impairment, neurological deficits, multicompartmental involvement, and hydrocephalus as compared with nongiant tumors (n = 139). Giant tumors also were less likely to undergo transsphenoidal resection and were associated with a higher rate of postoperative neurological morbidity. There were no significant differences between the 2 groups in terms of extent of resection, use of postoperative radiation therapy, and long-term endocrinological outcomes. Overall recurrence rates over a mean follow-up period of 4.1 years were similar between giant and nongiant tumors; however, recurrences after presumed gross total resection/near total resection were significantly higher in the former subgroup versus the latter (39.4% vs. 18.4%; P = 0.044). Risk factors for post-treatment obesity in giant craniopharyngiomas included adult age (P = 0.001), preoperative obesity (P = 0.003), and hypothalamic involvement (P = 0.012). CONCLUSION: Gross total resection/near total resection of giant craniopharyngiomas can be achieved at rates comparable to nongiant tumors. However, there remains a greater risk of postoperative neurological morbidity. Radiation therapy mitigates the risk of recurrence on long-term follow-up.

Association of Pre-Admission Statin Use With Reduced In-Hospital Mortality in COVID-19.

BACKGROUND: Coronavirus disease-19 (COVID-19) infection is associated with an uncontrolled systemic inflammatory response. Statins, given their anti-inflammatory properties, may reduce the associated morbidity and mortality. This study aimed to determine the association between statin use prior to hospitalization and in-hospital mortality in COVID-19 patients. METHODS: In this retrospective study, clinical data were collected from the electronic medical records of patients admitted to the hospital with confirmed COVID-19 infection from March 1, 2020 to April 24, 2020. A multivariate regression analysis was performed to study the association of pre-admission statin use with in-hospital mortality. RESULTS: Of 255 patients, 116 (45.5%) patients were on statins prior to admission and 139 (54.5%) were not. The statin group had a higher proportion of end stage renal disease (ESRD) (13.8% vs. 2.9%, p = 0.001), diabetes mellitus (63.8% vs. 35.2%, p<0.001), hypertension (87.9% vs. 61.1%, p < 0.001) and coronary artery disease (CAD) (33.6% vs. 5%, p < 0.001). On multivariate analysis, we found a statistically significant decrease in the odds of in-hospital mortality in patients on statins before admission (OR 0.14, 95% CI 0.03- 0.61, p = 0.008). In the subgroup analysis, statins were associated with a decrease in mortality in those with CAD (OR 0.02, 95% CI 0.0003-0.92 p = 0.045) and those without CAD (OR 0.05, 95% CI 0.005-0.43, p = 0.007). CONCLUSIONS: Our study suggests that statins are associated with reduced in-hospital mortality among patients with COVID-19, regardless of CAD status. More comprehensive epidemiological and molecular studies are needed to establish the role of statins in COVID-19.
