AimThe aim of this study is to present our experience in the management of hormonally active adrenal tumors in children.Material and methodsWe did a retrospective chart review of all children with hormonally active adrenal tumors evaluated at the endocrinology clinic and operated at our institution between 1983 and 2019.ResultsThere were 75 patients included in the study, 58 with adrenocortical tumors (ACTs) and 17 with pheochromocytomas (PCCs). Within the group of patients with ACTs, there were 41 females and 17 males. The mean age was 58.3 (SD: 87.9; range: 9–211) months. The clinical manifestation of the tumor's hormonal activity was virilization in 37 cases, Cushing syndrome in 5, and mixed in 16. A positive family history was present in 11 patients (18.9%). The mean tumor size was 48.2 (SD: 22.4; range: 7–120) mm. The pathological diagnosis was adenoma in 42 cases, carcinoma in 15 cases, and macronodular hyperplasia in 1. Median follow-up was 192 (range: 50–290) months. Tumor recurrence occurred in 6 patients (10.3%), and there were three disease-related deaths (5%). Within the group of patients with PCCs, there were 11 males and 6 females. The mean age was 146.7 (SD: 71.2; range: 60–216) months. A positive family history was present in 7 patients (41.2%). The mean tumor size was 36.6 (SD: 16.7; range: 7–120) mm. The pheochromocytoma was classified as benign in 15 cases and as malignant in 2. During a median follow-up of 180 (range: 127–300) months, recurrence was observed in 6 cases (35.3%) and disease-related death in 1 case (5.9%).ConclusionsProper diagnosis and management at our referral center were associated with a high cure rate, even in cases of malignant tumors. Familial surveillance is highly recommended.Level of evidenceLevel IV. 相似文献

The 9p21 locus has been deleted at a high frequency in a wide variety of tumors. Recently, two genes, p16INK4A and p15INK4B (also called MTS1 and MTS2), have been localized in close proximity at the 9p21 locus, encoding cyclin-dependent kinases 4/6 inhibitors of relative molecular mass 16 kD and 15 kD, respectively and also found to be deleted at a high frequency in tumor cell lines. We analyzed p16INK4A and p15INK4B genes in 178 cases of primary leukemias including 81 cases of chronic lymphocytic leukemia (CLL), seven of hairy cell leukemia (HCL), seven of chronic myelogenous leukemia (CML), 43 of acute myelogenous leukemia (AML), 27 of acute lymphoblastic leukemia (ALL), and 13 of myelodysplastic syndrome (MDS) by Southern blot analyses. The ALL cases showed a relatively high frequency of homozygous deletions (22%, 6 of 27) at the p16INK4A gene locus. Interestingly, of the six cases with p16INK4A homozygous deletions, only three showed homozygous deletions at the p15INK4B gene. In 81 CLL patients, we detected one homozygous and five heterozygous deletions at both the p16INK4A and p15INK4B genes and two heterozygous deletions at the p16INK4A gene alone. Deletion of these two genes in AML cases is relatively low (9%). We did not detect deletions in any of the MDS, HCL, and CML cases examined. Sequence analyses of p16INK4A gene of six CLL cases with heterozygous deletion at this locus showed a 27-bp deletion at the splice acceptor site of intron 1 in one case and changes in the coding sequence in three other cases. The data presented in this report showed that (1) p16INK4A and p15INK4B genes are preferentially deleted homozygously in ALL and heterozygously in CLL cases with frequent mutation in the second allele, and (2) p16INK4A gene appears to be more frequently deleted than p15INK4B gene. 相似文献

Background
Although the retrograde approach to nerve sparing (NS) aimed at maximizing NS during robot-assisted radical prostatectomy (RARP) has been described, its significant benefits compared to the antegrade approach have not yet been investigated.Objective
To evaluate the impact of NS approaches on perioperative, pathologic, and functional outcomes.Design, setting, and participants
Five hundred one potent (Sexual Health Inventory for Men [SHIM] score >21) men underwent bilateral full NS and were followed up for a minimum of 1 yr. After propensity score matching, 344 patients were selected and were then categorized into two groups.Surgical procedure
RARP with antegrade NS (n = 172) or RARP with retrograde NS (n = 172).Outcome measurements and statistical analysis
Functional outcomes were assessed using validated questionnaires. Multivariable logistic regression models were applied.Results and limitations
Positive margin rates were similar (11.1% vs 6.9%; p = 0.192), and no correlation with the NS approach was found on regression analysis. At 3, 6, and 9 mo, the potency rate was significantly higher in the retrograde approach (65% vs 80.8% and 72.1% vs 90.1% and 85.3% vs 92.9%, respectively). The multivariable model indicated that the NS approach was an independent predictor for potency recovery at 3, 6, and 9 mo, along with age, gland size, and hyperlipidemia. After adjusting for these predictors, the hazard ratio (HR) for the retrograde relative to the antegrade approach was 2.462 (95% confidence interval [CI], 1.482–4.089; p = 0.001) at 3, 4.024 (95% CI, 2.171–7.457; p < 0.001) at 6, and 2.145 (95% CI, 1.019–4.514; p = 0.044) at 9 mo. Regarding continence, the recovery rates at each time point and the mean time to regaining it were similar, and the method of NS had no effect on multivariable analysis. The absence of randomization is a major limitation of this study.Conclusions
In patients with normal erectile function who underwent bilateral full NS, a retrograde NS approach facilitated early recovery of potency compared to that with an antegrade NS approach without compromising cancer control. 相似文献9.

Context/Objective: To compare the beliefs and practices of individuals with spinal cord injury (SCI), their friends and family members (F&F SCI), and healthcare professionals (HCP) regarding complementary alternative medicine (CAM).Design: A questionnaire regarding CAM practices and beliefs was administered to participants on paper or online.Setting: An academic rehabilitation hospital.Participants: Ninety-six individuals voluntarily participated in the study. Participants included 28 patients with SCI, 36 F&F SCI, and 32 HCP.Interventions: Not applicableOutcome Measures: The questionnaire assessed participants’ prior or current use of 14 CAM modalities, their willingness to use CAM in the future or recommend its use, and their beliefs and opinions of CAM.Results: Participants with SCI and their family and friends, were more likely than HCP to have used CAM (P?≤?0.01 and P?≤?0.03, respectively) and recommend its use (P?≤?0.04 and P?≤?0.03, respectively). All three groups showed statistical significance in their willingness to ever use certain CAM modalities (P?≤?0.03 for SCI, P?≤?0.04 for F&F SCI, and P?≤?0.02 for HCP). SCI, F&F SCI, and HCP groups had similar beliefs and opinions regarding CAM.Conclusion: Patients with SCI as well as their friends and family, have significantly more experience with CAM and are more likely to recommend its use than HCP, suggesting that they are interested and find benefit in alternative healthcare. This warrants further investigation of the integration of CAM into general health practices for those with SCI. 相似文献
