Abstract
RATIONALE Atypical thymic carcinoid tumor is an exceedingly rare thymic neuroendocrine tumor derived from the cells of neuroendocrine system. Misdiagnosis or delayed diagnosis may result in disease progression to advanced stages and eventually leads to a poor prognosis. It is therefore necessary to make a correct diagnosis and provide an adequate treatment. PATIENT CONCERNS A 33-year-old Chinese male presented with numbness in bilateral lower extremities and general fatigue for a month. Chest computed tomography revealed a superior anterior mediastinal mass. Thymoma was initially considered, given the location of the mass and radiographic presentation. DIAGNOSIS Microscopic findings showed that the tumor cells are arranged in pseudoepitheliomatous growth or irregular nested growth pattern in a background of fibroconnective tissue, with focal infiltration into adipose tissue. The chrysanthemum-like structure or beam-like structure seen often in typical carcinoid tumor was not identified in this case. The tumor cells are spindled or oval, with focal active mitosis. The immunohistochemical staining showed strong positivity for CD56, CgA and Syn, positivity for CK, ACTH, and TTF-1, negativity for Vimentin, and ki67 labeled proliferation index was up to 10% in focal areas. According to the radiological and pathological findings, the diagnosis of atypical thymic carcinoid was made. INTERVENTIONS The patient underwent surgical resection of the mass. OUTCOME No recurrence or metastasis was identified during the follow up. LESSONS Because of its low incidencen, onspecific clinical symptoms, tissue location, and radiological findings, atypical thymic carcinoid tumor may sometimes be misdiagnosed as thymoma. Attention should be paid to avoid misdiagnosis.

Abstract
RATIONALE Endometrioid adenofibroma is a benign epithelial neoplasm of the ovary, most of which are often unilateral. The symptoms of endometrioid adenofibroma are often nonspecific and misleading. Therefore, a full understanding of the characteristics, diagnosis, and treatment methods of this disease is of great importance. In this study, we report a 34-year-old woman who was found with an unidentified mass on the right ovary during the physical examination 3 years ago with nosymptoms or signs. PATIENT CONCERNS A 34-year-old Chinese female was found with an unidentified 6 cm mass on the right ovary for 3 years that presented with no symptoms or signs. DIAGNOSIS Pelvic ultrasound revealed a 6 cm cystic solid mixed mass on the right ovary. Through histological and immunohistochemical examinations, the tumor mass was finally diagnosed as endometrioid adenofibroma of ovary. INTERVENTIONS To confirm the diagnosis, the ovarian tumor was laparoscopically resected. OUTCOMES The patient returned to hospital after 3 months with no recurrence or postoperative complications. LESSONS Endometrioid adenofibroma is a benign epithelial neoplasm of the ovary. Complete surgical resection is required and rare cases can recur. Postsurgical pathologic and immunohistochemical testing can confirm a diagnosis of endometrioid adenofibroma. It is important to understand of the key points of differential diagnosis of the disease due to the different prognosis and clinical treatment.

Abstract
Gliomas are the most common malignant tumor in the brain. As with other tumors, the progression of glioma depends on intra-tumoral angiogenesis. However, the effect of angiogenesis on gliomas is still not fully understood. In this study, we developed an angiogenesis pathway score using Gene Set Variation Analysis (GSAV) in R to assess the status of intra-glioma angiogenesis in The Cancer Genome Atlas (TCGA), Chinese Glioma Genome Atlas (CGGA mRNAseq_325, CGGA mRNA-array), and GSE16011 datasets. We found that the angiogenesis pathway score not only accurately predicted the prognosis of glioma patients, but also accurately distinguished the malignant phenotype and immune characteristics of gliomas. In addition, as an independent prognostic factor, the score could predict glioma sensitivity to radiotherapy and chemotherapy. In summary, we used the angiogenesis pathway score to reveal the relationship between glioma angiogenesis and the malignant phenotype, immune characteristics, and prognosis of glioma.

Abstract
RATIONALE Pulmonary artery intimal sarcoma is a rare tumor with exceptionally high mortality and easily misdiagnosed as pulmonary thromboembolism pulmonary thromboembolism (PTE) due to the nonspecific clinical presentation and symptom. Misdiagnosis or untimely diagnosis makes the disease progress to an advanced stage and eventually leads to a poor prognosis. PATIENT CONCERNS A 37-year-old Chinese female presented with chest tightness and dyspnea for 3 months. Echocardiography and chest computed tomography revealed an intraluminal obstruction of the pulmonary arteries. Tests of serum tumor makers showed slight elevation for carbohydrate antigen-125, and α-fetoprotein. PTE was suspected according to the radiological and laboratory findings. DIAGNOSIS Microscopic findings of the presumed thrombus showed prominent myxoid and edematous background with atypical spindled cells and curvilinear vascularity. Immunohistochemical staining demonstrated that the atypical spindled cells were positive for vimentin but negative for CK, S100, SMA, desmin, CD68, STAT6, CD34, β-catenin, ALK-p80, p53, and MDM2. According to the radiological and pathological findings, the diagnosis of fibrosarcoma of pulmonary artery was made. INTERVENTIONS The patient underwent surgical resection and the mass was excised as completely as possible. OUTCOME Follow-up information showed no evidence of recurrence or metastasis after 3 months postresection. LESSONS Because of the low incidence rate, nonspecific clinical symptoms, and radiological findings, primary fibrosarcoma of the pulmonary artery is commonly misdiagnosed as PTE. Pathological examination is necessary to confirm the diagnosis.

Abstract
This study was designed to explore the biological characteristics of a new oral streptococcus species Streptococcus oligofermentans. Plaque samples were collected from caries-free and caries-active subjects. S. oligofermentans was selectively grown on Mitis salivarius agar plates and identified by using 2-step PCR and was isolated from 38% of 18 subjects. Isolates were found mostly on healthy tooth surfaces. S. oligofermentans had weaker abilities in acid production and demineralizing hydroxyapatite. When Streptococcus mutans was coincubated with S. oligofermentans, total number, acid production and calcium release were significantly inhibited. In conclusion, inhibition of S. mutans could be a beneficial biological characteristic of S. oligofermentans in oral microecology.

Abstract
OBJECTIVE To examine the impact of clinician factors on technical data within an electrodiagnostic consultation for low-back pain and spinal stenosis. DESIGN Examiner differences on single-segment paraspinal mapping scores and other findings were examined in a prospective, masked, double-controlled trial involving 150 people aged 55-80 yrs who were selected for no symptoms, back pain, or possible spinal stenosis. RESULTS Unmasked clinicians were more variable than masked physicians (F2,219 = 4.808, P =or<0.01) and gave lower scores to people they felt had mechanical back pain. The percentage of inadequate segmental scores differed among clinicians (0-16.6%, F8,226 = 4.170, P < 0.001), with fellows having more difficulty than faculty (11.76 +/- 32.38% vs. 0.75 +/- 8.67%) (t233 = 3.753, P < 0.001). Correction of clinician bias improved the relationship between paraspinal score and subjects' ability to walk (weighted regression R = 0.129, B = -0.047, P < 0.001; unweighted regression R = 0.090, B = -0.045, P < 0.001). CONCLUSIONS Objective testing is adversely affected by clinician factors including prejudgment, experience, and individual idiosyncrasies. Less variation is found in more codified procedures. For electrodiagnostic consultation, correction of variability improves the relationship of test results to disability.

Abstract
OBJECTIVE To study mutans and non-mutans streptococci in patients after radiotherapy of the head and neck. METHODS Oral rinse samples collected from nasopharyngeal carcinoma patients before and after radiotherapy were diluted and cultured on nonselective and selective media for enumeration of total cultivable plaque flora, mutans and non-mutans streptococci and lactobacilli. Non-mutans streptococci were identified biochemically and by 16S rDNA sequence homology analysis. RESULTS After irradiation, mutans streptococci were not isolated; the levels of Streptococcus mitis and lactobacilli increased significantly. The level of Streptococcus salivarius increased, but the significance was the borderline. The level of Streptococcus sanguis decreased significantly after irradiation. The abundance of other oral streptococci species showed no significant changes. CONCLUSIONS S. mitis and S. salivarius are the predominant non-mutans streptococci in the high-caries-risk oral flora following radiotherapy.

Abstract
Musculoskeletal disorders are the leading cause of disability among people between 18 and 64 years of age. Patients with musculoskeletal injuries of the upper extremities are usually evaluated and treated by an individual physician and therapist. However, for patients who have problems, especially after being treated by a hand surgeon and a certified hand therapist, there are few other management options. A multidisciplinary assessment program for patients with chronic upper limb pain has not been described in the literature. As part of The University of Michigan RERC (Rehabilitation Engineering Research Center), the UPPER Program (UPper extremity Protocol Evaluation in Rehabilitation) was developed to evaluate patients who have disabling upper limb musculoskeletal disorders. At the center of the program is a multidisciplinary team composed of a physiatrist (physical medicine and rehabilitation specialist), occupational therapist, physical therapist, exercise physiologist, vocational counselor and pain psychologist. The UPPER Program elements include a pre-evaluation questionnaire, individual team member assessments and a team meeting. It is followed by a patient appointment with the team physician to review the results and recommendations. The essential details of the program are presented in this article so it can be reproduced elsewhere.

Abstract
Isolated posterior femoral cutaneous nerve (PFCN) lesions are rare, with only six cases reported in the modern literature and one case documented with a nerve conduction study. A 25-year-old woman had sensory loss in the posterolateral thigh after two right gluteal intramuscular injections. Nerve conduction studies using Dumitru's technique showed a 9microV response on the asymptomatic side, but no response on the symptomatic side, and no abnormalities on needle examination of the back and lower extremities. Although a single case does not prove the validity of a technique, this case provides the rare opportunity to demonstrate the utility of Dumitru's technique.

Abstract
Reflex sympathetic dystrophy is a syndrome characterized by superficial pain and tenderness associated with swelling, vasomotor instability, and dystrophic changes of the skin. In children, it is rarely reported and is felt to have a more benign and self-limited course. This case illustrates that, in children, reflex sympathetic dystrophy can occur without any previous history of trauma, and may be recurrent and migratory. A review of the literature is included. An 11-year-old girl, with no history of trauma, presented in 1992 with spontaneous onset of right leg pain. She was diagnosed with reflex sympathetic dystrophy, and she was treated unsuccessfully with oral medications. Her symptoms then resolved in 2 weeks after receiving epidural anaesthesia and aggressive physical therapy. Over the next 5 years, she presented to the paediatric rehabilitation clinic three times with recurrent RSD in her bilateral arms. The first two times were refractory to conservative management and resolved with four stellate ganglion blocks. The third recurrence persisted with three stellate ganglion blocks and resolved with gabapentin.

Abstract
Various aziridine derivatives derived from diamines were studied in several biological systems to evaluate their effects on reproduction and as potential mutagens. Considerable variations in the biological activities of these compounds were seen among animal species and among the varied chemical structures. In general, mutagenic responses paralleled the antifertility effects in mice and houseflies and the anticancer effects in mice. The lack of an antifertility effect by N,N'-bis(aziridinylacetyl)-1,8-octamethylenediamine in the rat was quite unexpected in view of its chemosterilant activity in houseflies and mice.
