Pediatric Meningioma

BACKGROUND Pediatric meningiomas are rare, and only a few cases attributed to trauma and characterized by development at the site of bone fracture have been reported. Both pediatric and traumatic meningiomas have aggressive characteristics. OBSERVATIONS An 11-year-old boy who sustained a head injury resulting from a left frontal skull fracture 8 years previously experienced a convulsive attack. Imaging revealed a meningioma in the left frontal convexity. Total removal of the tumor with a hyperostotic section was successfully achieved. Intraoperative investigation showed tumor invasion into the adjacent frontal cortex. Histologically, the surgical specimen revealed a transitional meningioma with brain invasion and a small cluster of rhabdoid cells. This led to a final pathological diagnosis of an atypical meningioma with rhabdoid features. The postoperative course was uneventful, and no recurrence of the tumor was found after 2 years without adjuvant therapy. LESSONS This is the first report of a pediatric meningioma with rhabdoid features occurring at the site of a skull fracture. Meningiomas that contain rhabdoid cells without malignant features are not considered to be as aggressive as rhabdoid meningiomas. However, the clinical course must be carefully observed for possible long-term tumor recurrence.

Adenoid cystic carcinoma is one of the most common salivary gland malignancies with poor long-term prognosis, but the coexistence of sialoliths is extraordinarily rare. In this article, we report a case of 30-year-old woman with a history of submandibular area swelling with intermittent pain increasing during mealtimes that had led her attending physician to diagnose a sialolith in the left submandibular gland on a radiograph 10 years before. However, the surgical specimen proved to be an adenoid cystic carcinoma accompanied with a sialolith. Histopathologically, the submandibular gland was displaced with a fibrous granulation tissue containing a small cribriform carcinoma invading the extracapsular region of the gland. We performed fluorescence in situ hybridization examination with an MYB-NFIB fusion probe of the lesion, with positive results. The patient underwent a supraomohyoid neck dissection as additional procedure because of the possibility of the extracapsular cancer nest remaining around the submandibular gland, but she remains well and disease free 11 years after the first operation.

Abstract BACKGROUND: Craniopharyngiomas (CRPs) often cause visual deterioration (VD) due to the close vicinity of the optic apparatus. OBJECTIVE: To evaluate longitudinal visual outcomes after surgery of CRP and determine the prognostic factors thereof. METHODS: One hundred forty-six adult patients who underwent surgery for newly diagnosed CRP were retrospectively reviewed. There were 87 male patients (60%), and the median age was 41 years (range, 18–75). The mean follow-up duration was 88.7 months (range, 24–307). A visual impairment score was used to assess the short-term (<1 month) and long-term (>2 years) visual outcomes. RESULTS: Gross total removal was performed in 53 patients (36%), and tumor recurrence occurred in 40 patients (27%). The average preoperative, short- and long-term visual impairment scores were 44.4, 38.5, and 38.1, respectively, on a 0- to 100-point scale (with 100 indicating the worst vision). Short- and long-term VD occurred in 28 (19%) and 39 patients (27%), respectively. Subtotal removal (STR) alone (P = .010; OR = 4.8), short-term VD (P < .001; OR = 39.7), and tumor recurrence (P < .001; OR = 28.2) were significant risk factors for long-term VD in the multivariate analysis. Patients undergoing STR alone had higher tumor recurrence rates in comparison with those who underwent gross total removal or STR with adjuvant therapy (P < .001). CONCLUSION: Short-term VD secondary to the surgical insult and the recurrence of the tumor were strong predictors of long-term visual outcomes after surgical treatment for CRP. STR alone may be an ineffective strategy for achieving tumor control and optimal visual outcomes in patients with CRP.

Background Remnant gastric cancer (RGC) encompasses all cancers arising from the remnant stomach. Various studies have reported on RGC and its prognosis, but no consensus on its surgical treatment and postoperative management has been reached. Moreover, the correlation between the clinicopathological characteristics and long-term outcomes of RGC remains unclear. This study investigated the clinicopathological factors associated with the long-term survival of RGC patients. Methods The medical records (March 1993-September 2020) of 104 RGC patients from Tokyo Medical University Hospital database were analyzed. Of these 104 patients, the medical records of 63 patients who underwent surgical curative resection were analyzed using R. Kaplan-Meier plots of cumulative incidence of RGC were made. Differences in survival rates were compared using the log-rank test. Prognostic factors were analyzed using multivariate Cox regression analysis ( P < .05). Results Of the 104 RGC patients, 63 underwent total remnant stomach excision. The median time from the first surgery to the total excision was 10 years. The 5-year survival rate of the 63 RGC patients was .55 ((95% CI); .417-.671). The clinicopathological factors that were significantly associated with the long-term outcome of the RGC patients were tumor diameter (≥3.5 cm), presence or absence of combined resection of multiple organs, tumor invasion (deeper than T2), TNM stage, and postoperative morbidity. The multivariate Cox regression analysis showed that tumor invasion depth was the only independent prognostic factor for RGC patients [HR (95% CI): 5.49 (2.629-11.5), P ≤ .005]. Conclusions Among prognostic factors, tumor invasion depth was the only independent factor affecting RGC’s long-term outcome.

E-governance uses Internet and communication technologies to automate governance in innovative ways, so that it becomes more efficient, more cost-effective, and empowers the human race even more. E-governance exercises are being attempted for more than a decade now, but have so far achieved only mixed success. The long-term prognosis for e-governance, however, remains extremely positive. The emergence of Web-services technologies, the continually proliferating computer networks, and the irreversible migration towards digital information strongly confirm the view that e-governance is here to stay. The eventual success of any e-governance project is intimately linked to the methodology used, and to that complex mesh between men, machines, and mindsets. We explain the “what,” “why,” and “how” of e-governance. We also talk of e-governance concerns, and discuss a few illustrative case studies.

Enchondromas are benign tumours that may become symptomatic due to expansive pressure on the surrounding bone. In this case, a 27-year-old male developed a symptomatic enchondroma within the proximal phalanx of his left fourth toe. Resection and insertion of a bone graft were considered optimal management. Histopathology testing confirmed the diagnosis of an isolated enchondroma. The patient was monitored closely for 3 months postoperatively and reported full satisfaction at his 12-month review. Enchondroma resection and insertion of a tibial bone graft may provide an effective long-term solution for a symptomatic enchondroma of the toe.

The Stability

A two-stage SBR system treating the wastewater containing copper-phthalocyanin dye-Reactive Turquoise Blue KN-G (C. I. Reactive Blue 21, denoted by RTB) was investigated during a 200-cycle operation. The performance of the system, including pollutant removal rates, operating stability and sludge characteristics, may be a concern in the long-term run. The results shows that the system removed RTB efficiently despite the step-up RTB concentration from 13.1 to 107 mg/L in the influent. The average total removal rates of RTB were 81% to 92.5% due to the contribution of both anaerobic and aerobic stages, while stable effluent was produced with the help of the aerobic stage. The sludge in each reactor was in the steady state and of good activity on RTB removal. Moreover, the anaerobic sludge with the SVI value of 109.1 and the aerobic sludge with the SVI value of 103.2 had good settling properties, which was verified by hardly any presence of suspended solids in the effluent and an observation under an electron-scanning microscope. The adsorption and biodegradation were considered as the mechanism for the stability of the SBR system during the long-term run.

Object. The goal of this study was to provide epidemiological and clinical data on the management of cavernomas of the basal ganglia and brainstem from a long-term series at one institution. Methods. All 68 patients who were referred to the authors' department between 1992 and 2000 for deep cavernomas were evaluated by clinic examinations, review of neuroimaging examinations, and review of charts and operative notes. Twenty-nine patients underwent microsurgical procedures, which carried a 69% risk of transitory neurological deterioration. Radical excision was achieved in 25 of these patients, as determined by a review of neuroimages; the remaining four patients all experienced new hemorrhages that led to increased morbidity or even to mortality. Surgical results were better if surgery was performed early, within 1 month posthemorrhage, than if operations were postponed. In selected patients, deep lesions not reaching a pial surface could be safely removed from the thalamus, basal ganglia, or medulla oblongata. Of five patients who underwent gamma knife surgery, two experienced hemorrhages, one at 2 and the other at 5 years following treatment. Patients who did not undergo surgery had a yearly incidence of hemorrhage that was 2% in cases of incidental cavernomas and 7% in symptomatic ones. Conclusions. Over the long term, outcomes were worse following conservative treatment or shunt insertion surgery than after microsurgery of symptomatic cavernomas. Incidental cavernomas carried a low risk of neurological deterioration. Surgery should follow generally accepted indications, but only with the confidence that total removal can be safely achieved. Surgery that is performed within 10 to 30 days following ictus may be preferable to delayed surgery.

ABSTRACT Transsphenoidal surgery is an efficacious treatment for patients with prolactin (PRL)-secreting adenomas, even if disrupted pituitary-hypothalamic relationships may persist and/or a recurrence of the PRL-secreting tumor can occur. In this paper, we analyze the long-term follow-up of 119 consecutively treated women who underwent transsphenoidal microsurgery for PRL-secreting adenomas. Apparent total removal of the tumor was achieved in 98 patients who had enclosed tumors (58 with Grade-I tumors and 40 with Grade II). In the remaining patients, the removal was considered partial. Persistent normal basal PRL levels were achieved in 61 patients who had apparent total removal of the adenoma (44 with Grade I tumors and 17 with Grade II). Of the remaining 37 patients in whom surgical removal of the adenomatous tissue was thought to be total, 30 had persistent nonevolutive, high PRL levels ranging from 21 to 196 ng/ml, without clinical and radiological signs of tumor regrowth, and 7 with PRL levels ranging from 56 to 560 ng/ml had a recurrence of the PRL-secreting tumor. These data seem to indicate that a slightly elevated postsurgical PRL value does not imply that tumoral tissue is still present. Nontumoral conditions (i.e., a secondary empty sella) could induce functional hyperprolactinemia.
