INTRODUCTION
Gastric glomus tumors are fairly uncommon and mostly benign, with an estimated incidence of 1% of all GI soft tissue tumors. The most common GI site of involvement is the stomach, and in particular the antrum. Some cases have been discovered incidentally, but most are symptomatic presenting with GI bleeding, perforation or abdominal pain. Glomus tumors are submucosal tumors and hence mistaken with the more frequent gastrointestinal stromal tumors.PRESENTATION OF CASE
A 33-year-old woman presented with intermittent dull upper abdominal pain for two days. Abdominal computed tomography (CT) was performed showing a hyperdense mass in the antrum. Endoscopy and endoscopic ultrasound revealed a submucosal antral mass along the greater curvature, suspicious for a gastrointestinal (GI) stromal tumor (GIST), a laparoscopic antrectomy with Billroth I reconstruction was done. Pathological examination revealed that the mass was a gastric glomus tumor.DISCUSSION
The presented case report met all the usual standard criteria commonly used to identify glomus tumors, the uniqueness of the case lies in the occurrence of the glomus tumor in the stomach, first suspected as GIST, then confirmed as a gastric glomus tumor. The vast majority of glomus tumors of the GI tract have been described in the gastric antrum. They occur in adults of all ages with a significant female predominance (78%).CONCLUSION
This case may aid in improving the recognition and diagnosis of this rare entity and in differentiating it from more common GISTs and gastric carcinoids. A built up knowledge between physicians is extremely necessary to avoid common confusion in taking the right medical approach.Abbreviations: CT, computed tomography; GI, gastrointestinal; GIST, gastrointestinal stromal tumor; EU, emergency unit; EUS, endoscopic ultrasound; SMA, smooth muscle actin; KIT, proto-oncogene c-Kit or tyrosine-protein kinase Kit or CD117; AFIP, Armed Forces Institute of Pathology; AUBMC, American University of Beirut Medical Center 相似文献2.
Background
A glomus tumor is a rare neoplasm usually found in the dermis or subcutaneous tissue of the extremities. It is rare for the glomus tumor to occur on the head and face. Only 26 glomus tumors of the oral region and affected bone have been reported in the English-language literature (Table 1). We report a case of a glomus tumor at the mandible. As a new point, the glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible.Case presentation
The patient was a 44-year-old Japanese man who complained swelling of the right mandible. Radiographic examination showed a multilocular radiolucency area in the left mandible. Radiographic findings on our case resembled those of a common benign tumor. The lesion occupied to the premolar and molar area and revealed that the tumor resorbed the roots of the teeth. The lesion was removed surgically with the buccal cortical bone and buccal mucosa in contact with the mass of the tumor. The mass fully excised intraorally under general anesthesia, and the inferior alveolar nerve in contact with the mass was preserved.The specimen was pathologically diagnosed as a glomus tumor. Immunohistochemical staining was positive for vimentin, muscle-specific actin/HHF35, and calponin. A hairline-shaped area of positive staining for type IV collagen surrounding the tumor cells was also observed. In contrast, staining for alpha-SMA, cytokeratin (AE1/AE3), cytokeratin (CAM5.2), CK19, CD31, CD34, CD68, p63, S-100, Factor VIII, and desmin was all negative. The Ki-67 labeling index was almost 1%.A recurrent tumor was again detected in the site below the primary tumor at an 8-year follow-up, and it was surgically removed. The patient has had no symptoms of recurrence in 2 years after the second operation.Conclusion
The glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible. The immunohistochemical features of the tumor were consistent with those described in previous reports. It is important to completely remove the Glomus tumor.3.

Background
A method for the identification of semi‐active fiducial magnetic resonance (MR) markers is presented based on selectively optically tuning and detuning them.Methods
Four inductively coupled solenoid coils with photoresistors were connected to light sources. A microcontroller timed the optical tuning/detuning of coils and image collection. The markers were tested on an MR manipulator linking the microcontroller to the manipulator control to visibly select the marker subset according to the actuated joint.Results
In closed‐loop control, the average and maximum were 0.76° ± 0.41° and 1.18° errors for a rotational joint, and 0.87 mm ± 0.26 mm and 1.13 mm for the prismatic joint.Conclusions
This technique is suitable for MR‐compatible actuated devices that use semi‐active MR‐compatible markers. 相似文献4.

Background
Transoral robotic surgery (TORS) using the Single-Port system (SPS) relies on electrocautery, limiting its applications in the upper aerodigestive tract. We evaluated the feasibility of a CO2 delivery system for the SPS.Methods
Otolaryngology residents performed a cutting exercise using a handheld CO2 laser and participated in a cadaveric oropharyngeal dissection using the SPS with monopolar cautery (SP + EC) and CO2 laser (SP + CO2). Residents completed the System Usability Scale (SUS) questionnaire to evaluate these techniques.Results
The same laser fiber was used for all combined dissections. The handheld CO2 laser, SP + EC, and SP + CO2 demonstrated similar SUS scores. On individual domain scores, SP + CO2 received less favorable ratings compared to the handheld CO2 laser for complexity, integration, and cumbersome experience (p < 0.05). On subgroup stratification, less TORS experience was associated with worse SUS scores.Conclusion
SP-guided CO2 laser delivery is a viable alternative to electrocautery in robotic surgery, and should be considered when performing TORS. 相似文献5.

Background
We analyze our outcomes utilizing imported allografts as a strategy to shorten wait list time for pancreas transplantation.Methods
This is an observational retrospective cohort of 26 recipients who received either a locally procured (n = 16) or an imported pancreas graft (n = 10) at our center between January 2014 and May 2017. Wait list times of this cohort were compared to UNOS Region 9 (New York State and Western Vermont). Hospital financial data were also reviewed to analyze the cost‐effectiveness of this strategy.Results
Imported pancreas grafts had significantly increased cold ischemia times (CIT) and peak lipase (PL) levels compared to locally procured grafts (CIT 827 vs 497 minutes; P = .001, PL 563 vs 157 u/L; P = .023, respectively). There were no differences in graft or patient survival. The median wait time was significantly lower for simultaneous kidney‐pancreas transplants at our center (518 days, n = 21) compared to Region 9 (1001 days, n = 65) P = .038. Despite financial concerns, the cost of transport for imported grafts was offset by lower standard acquisition costs.Conclusions
Imported pancreas grafts may be a cost‐effective strategy to increase organ utilization and shorten wait times in regions with longer waiting times. 相似文献6.

Background
Impairment of haptic perception by surgical gloves could reduce requirements on haptic systems for surgery. While grip forces and manipulation capabilities were not impaired in previous studies, no data is available for perception thresholds.Methods
Absolute and differential thresholds (20 dB above threshold) of 24 subjects were measured for frequencies of 25 and 250 Hz with a Ψ‐method. Effects of wearing a surgical glove, moisture on the contact surface and subject's experience with gloves were incorporated in a full‐factorial experimental design.Results
Absolute thresholds of 12.8 dB and ?29.6 dB (means for 25 and 250 Hz, respectively) and differential thresholds of ?12.6 dB and ?9.5 dB agree with previous studies. A relevant effect of the frequency on absolute thresholds was found. Comparisons of glove‐ and no‐glove‐conditions did not reveal a significant mean difference.Conclusions
Wearing a single surgical glove does not affect absolute and differential haptic perception thresholds. 相似文献9.

Aim
Chronic anal fissures (CAFs) are frequently encountered in coloproctology clinics. Chemical sphincterotomy with pharmacological agents is recommended as first‐line therapy. Topical nitrates (TN) heal CAF effectively but recurrences are common. An alternative treatment modality is injection of botulinum toxin (BT) into the anal sphincter. We aimed to perform an updated systematic review and meta‐analysis to compare the effectiveness of BT and TN in the management of CAF.Method
PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until March 2017. All randomized controlled trials (RCTs) that reported direct comparisons of BT and TN were included. Two independent reviewers performed methodological assessment and data extraction. Random effects models were used to calculate pooled effect size estimates.Results
Six RCTs describing 393 patients (194 BT, 199 TN) were included. There was significant heterogeneity among the trials. On random effects analysis there were no significant differences in incomplete fissure healing (OR = 0.47, 95% CI 0.13–1.68, P = 0.24) or recurrence (OR = 0.70, 95% CI 0.39–1.25, P = 0.22) between BT and TN, respectively. BT was associated with a higher rate of transient anal incontinence (OR = 2.53, 95% CI 0.98–6.57, P = 0.06) but significantly fewer total side effects (OR = 0.12, 95% CI 0.02–0.63, P = 0.01) and headache (OR = 0.10, 95% CI 0.02–0.60, P = 0.01) compared with TN.Conclusion
BT is associated with fewer side effects than TN but there is no difference in fissure healing or recurrence. Patients need to be warned regarding the risk of transient anal incontinence associated with BT. 相似文献16.
