Pediatric angiocentric glioma with acute intracerebral hemorrhage: A case report with 36 months follow-up.

BACKGROUND: Angiocentric glioma (AG) is an extremely rare intracranial tumor that was first described in 2005 and identified as a special type of intracranial tumor in 2007 by the WHO, which mainly affects children and young adolescents. Epilepsy is the main presentation; therefore, it was recognized as a seizure-related tumor in the past. Here, we report a case of AG with acute intracerebral hemorrhage (ICH) as the first symptom who never had a seizure onset. CASE DESCRIPTION: A 3-year-old girl with the right limb weakness was admitted to our hospital 4 h after onset in 2018. Computed tomography showed a hematoma of about 20 ml accompanied by a hyper/iso-dense spheroid lesion located in the sub-cortex of the left parietal lobe. Magnetic resonance image (MRI) showed signs of hypointense signal in T1, T2, and fluid-attenuated inversion recovery sequence, distinct enhancement of this tumefactive lesion in the contrast-enhanced sequence. Thus, the admission diagnosis was neoplasm with acute ICH. A gross total resection of the tumor was achieved by parietal craniotomy. The histopathological diagnosis was AG. No signs showed tumor recurrence after 36 months of follow-up. CONCLUSION: This is the sole case of AGs with acute intracranial hemorrhage as the first symptom without any kind of epilepsy by far. This case had unique MRI signs that were different from the previous description. This case enriches the clinical and radiological manifestations of AG and reveals that further investigations are needed to further understand AG.

A Cohort Study on Associations between Fundus/intraocular Pressure Abnormality and Medical Check-up Items.

PURPOSE: To evaluate the associations between medical check-up items (MCI) for fundus and intraocular pressure abnormality (FIPA) diseases in the Department of Health Management Centre, the Fifth Affiliated Hospital of Sun Yat-sen University (DHMC-FHS). PATIENTS AND METHODS: Individuals who visited DHMC-FHS and underwent MCI between June 2017 to May 2019 were included, 3237 subjects. A total of 356 participants were diagnosed as FIPA and enrolled. The general clinical characteristics were collected. Diseases for FIPA diagnosed included five cohort, high intraocular pressure, diabetic retinopathy, hypertension fundus arteriosclerosis, large eye cup, and high myopia fundus changes. Possible impact factors of MCI included blood routine, B-ultrasound, heart rate, hypertension, hyperlipidemia, standard vision, cerebral arteriosclerosis, body mass, arterial/carotid arteriosclerosis, etc. Further, the Pearson's correlation coefficients and logistic regression analyses were used to examine associations between MCI and FIPA. RESULTS: The weighted study population who belonged to FIPA included 356 subjects. There were significant differences in age, IOP, habitual exercise, smoking, sleep duration (P˂0.05) between FIPA and without FIPA. And RBC, Hemoglobin, B-ultrasound abnormal event, heart rate, systolic pressure, diastolic pressure, TC, LDL-C, standard vision, cerebral arteriosclerosis, body mass index, carotid arteriosclerosis were positively correlated with high intraocular pressure, hypertension fundus arteriosclerosis and high myopia fundus changes (P < .05). Possible prognosis risk factors, higher IOP, habitual exercise and more frequent smoking affect FIPA prognosis significantly [Odds ratio (OR) = 0.53, P = .01; OR = 0.13, P = .03; OR = 0.83; P = .04, respectively]. CONCLUSION: Of FIPA participants, high intraocular pressure, hypertension fundus arteriosclerosis and high myopia fundus changes were shown a positive relationship with MCI. Control IOP, habitual exercise and less frequent smoking were regarded as positive associations with decreased FIPA. These findings could help us prevent and diagnose FIPA diseases in time via MCI.

Adult granulosa cell tumors of bilateral ovaries with pure cystic presentation: A case report and review of literature.

RATIONALE: Granulosa cell tumors (GCTs) are rare, hormonally active sex cord-stromal tumors that generally present as solid unilateral ovarian lesions. It's quite uncommon that they present as pure bilateral ovarian cysts. Histopathology remains the gold standard for making a diagnosis of GCTs. However, as the differential diagnosis is difficult, cystic GCTs are frequently misdiagnosed as benign or other cystic tumors either prior to surgery or during pathologic diagnosis. Accordingly, herein, we describe a fairly rare case of bilateral ovarian cystic GCTs, along with a review of the related literature. PATIENT CONCERNS: A 43-year-old woman presented with abdominal distension and chronic pain since 1 day. The patient had a history of dysmenorrhea. DIAGNOSES: Physical examination revealed palpable bilateral adnexal tumors; ultrasonography revealed cystic and septate masses with a maximum diameter of 7.8 and 10.7 cm, respectively, in the bilateral ovaries. Hormonal analysis revealed that the blood estradiol levels were elevated. Postoperative pathological and immunohistochemical examinations of the surgical specimens revealed a final diagnosis of cystic adult GCTs of the ovaries. INTERVENTIONS: The patient first underwent laparoscopic bilateral ovarian cystectomy. On the basis of the final pathological diagnosis report, abdominal total hysterectomy, bilateral oophoro-salpingectomy, and partial omentectomy were then performed. Microscopic examination revealed that there were no residual CGT cells. The patient's federation international of gynecology and obstetrics (FIGO) Stage was IB period. OUTCOMES: The surgeries were successful. The tumor was a FIGO Stage IB tumor, and the patient did not require any additional treatment. The patient had been followed-up regularly for 2 years after surgery; she did not experience any complications and remained disease-free. LESSONS SUBSECTIONS: Cystic GCTs should be considered in the differential diagnosis if a female patient shows bilateral ovarian cysts. They are extremely rare ovarian malignant tumors that must be differentiated from other ovarian tumors, especially purely cystic tumors and benign cysts. Although pathological and immunohistochemical findings are important for making the diagnosis, the varying histopathological features on microscope make diagnosis difficult, including tumor cells with luteinization or free cell clusters. The current case highlights the importance of physicians being aware of and suspecting cystic CGTs in similar cases, along with knowing the characteristics of GCTs for the diagnosis and differential diagnosis.

A rare coexistence of parathyroid adenoma and medullary and papillary thyroid carcinoma.

The combination of parathyroid adenoma, medullary thyroid carcinoma (MTC), and papillary thyroid carcinoma (PTC) has been reported occasionally, but it has now been recognized more often through effective evaluations. However, the etiology and risk factors remain unclear, so we discuss them in this article. Here, we report the case of a 64-year-old woman with parathyroid adenoma, MTC, and PTC diagnosed incidentally. This woman was admitted to the Xingtai People's Hospital affiliated to Hebei Medical University for an apparently aggravating symptom of hypodynamia. Her past medical history included diabetes and a left nephrolith. Upon admission, her bloodwork showed hypercalcemia, hypophosphatemia, and elevated serum parathyroid hormone. Subsequently, the sonographic findings revealed dominant nodules in both the right and left lobes with a left inferior suspected parathyroid adenoma. The patient underwent fine needle aspiration (FNA) of the bilateral thyroid lobes, the results of which were both thyroid carcinoma. Therefore, a thyroidectomy, a neck dissection, and the excision of a suspected parathyroid adenoma were performed. A histological examination revealed a combination of parathyroid adenoma, MTC, and PTC. Her serum calcium and parathyroid hormone levels returned to the normal range after the surgery. Our case highlighted the fact that even though the concurrent existence of parathyroid adenoma, MTC, and PTC is rare, the diagnosis of this coexistence should be considered in primary hyperparathyroidism (PHPT). To avoid repeat surgeries, patients with coexisting diseases should be screened cautiously. Therefore, we recommend a preoperative check of the calcium levels in patients with thyroid cancer and a preoperative thyroid check in all patients with PHPT.

Evaluation on the application of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency.

BACKGROUND: To evaluate the diagnostic value of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency (VBI) during clinical diagnosis and treatment METHODS: Eighty patients diagnosed with VBI in our hospital from June 2018 to December 2019 were randomly selected as the observation group, and 80 healthy people who received physical examination in the same period were selected as the control group. The abnormal rate, main performance and results, and the peak velocity of blood flow and vertebrobasilar artery blood flow of the two groups were compared. RESULTS: The abnormal rate of EEG and TCD in VBI patients was 38.75% (31/80) and the 93.75% (75/80), respectively. In TCD examination, ACA, PCA, MCA, and VA of both sides of the observation group were higher than those of the control group, while BA was lower than that of the control group (P < 0.05). The Vs, Vd, and Vm on both sides of BA and VA in the observation group were lower than those in the control group, while PI and RI were higher than those in the control group (P < 0.05). CONCLUSIONS: TCD examination is highly sensitive to the degree and pattern of cerebral ischemia in VBI patients. EEG examination will define the changes of brain cell function after cerebral ischemia. Therefore, EEG and TCD have their own advantages. The application of TCD and EEG can be considered in the early diagnosis, curative effect, and prognosis evaluation of VBI patients, so as to improve the accuracy of diagnosis and prognosis.

Prognostic value of miR-17-5 p in gastrointestinal cancers: a systematic review and meta-analysis.

BACKGROUND: There are accumulating studies investigating the aberrant expression of microRNAs in tumor patients. As an important member of miR-17/92 cluster, miR-17-5 p has been identified as a potential prognostic factor for survival in tumor patients. We conducted this meta-analysis aimed to assess the effect of miR-17-5 p as a prognostic biomarker for gastrointestinal tumor patients. MATERIALS AND METHODS: Eligible studies were enrolled by searching the online databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and WanFang Data until September 2017. We calculated pooled hazard ratios (HRs) and 95% CI of miR-17-5 p for overall survival and disease-free survival. RESULTS: In the categorical variable analysis, we identified 11 studies with 1,279 patients. The pooled analyses suggested that overexpression of miR-17-5 p may predict poor overall survival (HR = 1.86, 95% CI: 1.55-2.25, P<0.001) and disease-free survival (HR = 1.43, 95% CI: 1.01-2.03, P=0.046) in patients with gastrointestinal tumors. Subgroup analysis showed the pooled HR of overall survival was more significant in tissue specimen, Asian patients, and digestive tract tumors. But there was no correlation between the outcomes and European patients. CONCLUSIONS: This meta-analysis suggested that miR-17-5 p has predictive effects on overall survival and disease-free survival of patients with gastrointestinal tumors.

Different expression pattern and significance of p14ARF-Mdm2-p53 pathway and Bmi-1 exist between gastric cardia and distal gastric adenocarcinoma.

Recent studies have suggested that adenocarcinoma of gastric cardia (GCA) is distinct from distal stomach, with different risk factors, tumor characteristics, and biological behavior. The aim of this study is to evaluate the possible difference in the expressions of p14ARF, Mdm2, p53, and Bmi-1 by immunohistochemical staining on paraffin-embedded tissues of gastric cardia adenocarcinoma (GCA; n = 74) and distal gastric adenocarcinoma (DGA; n = 41). The results showed that the percentage of p14ARF-negative expression, Mdm2 overexpression, p53-positive expression, and p53 pathway abnormality (p14ARF(-)/Mdm2(+)/p53(+)) were all significantly higher in GCA than those in DGA (P < .05). Further analysis showed that in GCA, the negative expression of p14ARF was significantly associated with poor differentiation, Mdm2 overexpression with tumor stage and lymph node metastasis, and positive p53 expression with tumor stage (P < .05), whereas in DGA, only Mdm2 overexpression was related with well/moderate differentiation (P < .05). Abnormality of the p53 pathway was significantly correlated with poorer differentiation only in GCA (P < .05). The positive expression of Bmi-1 in all cases of GCA and DGA was significantly higher than normal gastric mucosa epithelium, but no difference was found between GCA and DGA (P > .05). Thus, the results in this study confirmed that different expression pattern and clinicopathologic significance of the p14ARF-Mdm2-p53 pathway did exist between GCA and DGA. The results further support the hypothesis that different mechanisms may be involved in the development and progression of adenocarcinoma from cardia and distal portion of stomach.
