Abstract:

In Japanese pediatric patients with thyrotropin (TSH) resistance, the R450H mutation in TSH receptor gene (TSHR) is occasionally observed. We studied the frequency and clinical implication of the R450H mutation inTSHRin the general population of Japanese adults using smart amplification process 2 (SmartAmp2). We designed SmartAmp2 primer sets to detect this mutation using a drop of whole blood. We analyzed thyroid function, antithyroid antibodies, and this mutation in 429 Japanese participants who had not been found to have thyroid disease. Two cases without antithyroid antibodies were heterozygous for the R450H mutation inTSHR. Thus, the prevalence of this mutation was 0.47% in the general population and 0.63% among those without antithyroid antibodies. Their serum TSH concentrations were higher than the average TSH concentration not only in subjects without antithyroid antibodies but also in those with antithyroid antibodies. The R450H mutation inTSHRis relatively common in the Japanese population and potentially affects thyroid function. The present study demonstrates that the SmartAmp2 method is useful to detect the R450H mutation inTSHR, which is one of the common causes of TSH resistance in the Japanese population.

Abstract:

Se evalúan algunas características presentadas a la hora de garantizar calidad de servicio como son el ancho de banda y la pérdida de paquetes, sobre una topología de red que involucra tres tipos de tráfico (CBR, Pareto y Exponencial). Se implementan cinco configuraciones diferentes en el simulador de redes NS2, donde el primero corresponde a un caso sin QoS, con una capacidad de canal que es suficientemente grande para trasmitir los tres tipos de tráfico, mientras que en las siguientes cuatro configuraciones la capacidad se reduce a un menor tamaño y se estudian diferentes casos de calidad de servicio.Para observar el comportamiento de los tráficos se implementa inicialmente una red sin QoS con dos tipos de encolamiento y posteriormente se realiza una configuración que implementa QoS mediante los modelos IntServ y DiffServ.Los resultados obtenidos de estas simulaciones son graficados y comparados con el fin de determinar el comportamiento más adecuado en redes IP.

Abstract:

Internet growth in recent years has encouraged many new applications to be provided for the end user. However, providing and maintaining high quality of service for these new applications is a challenging matter that is getting the attention of many many researchers nowadays. The QoS challenge is emanating from the diversity of these applications, in term of bandwidth requirements and high sensitivity to delay and delay variation. Three main architectures were proposed by IETF in an effort to make the IP QoS a reality. They are integrated services (Intserv), differentiated services (DiffServ) and multiprotocol label switching (MPLS). Sometimes perceived as competitor, these architectures are in fact complementary developments that approach the QoS challenge from different network perspectives. Thus these approaches can work together in a manner that provides a global QoS within Heterogeneous network. This paper aims to propose and discusses an improved admission control mechanism in order to achieve a global QoS in the HN Network. The proposed mechanism uses MPLS-TE tunnels at the core of Heterogeneous networks to maintain QoS for inter-domain flows and applications.

Abstract:

In general, data exchanged on an industrial network can be classified into two groups: realtime and non-realtime data. Non-real-time data do not have stringent time limits on their communication delays experienced during the data exchange. In contrast, real-time data have very strict time limits and the data’s value is diminished greatly as the communication delay grows larger. Therefore, when building an industrial network, the designer must configure the network to satisfy these requirements. MPLS provides extensive support for both integrated services/RSVP, and diff-serv QoS classes. Service providers can use MPLS to define classes of service (gold, premium, best-effort, etc.) and to define per-hop behavior (PHB) for each class to support the service. We use OPNET Modeler to design MPLS capabilities incorporating IntServ/DiffServ mechanisms into on an industrial network to ensure QoS under network failure conditions. We demonstrate how modern MPLS with QoS management techniques can control, but also complicate, prediction, and will finally illustrate how semi-empirical statistical techniques offer some resolution.

Abstract:

The key to the asynchronous traffic shaping (ATS) technology being standardized in IEEE 802.1 time sensitive network (TSN) task group (TG) is the theorem that a minimal interleaved regulator (IR), attached to a FIFO system does not increase delay upper bound while suppresses the burst accumulation. In this work it is observed that the FIFO system can be a network for flows that share same input/output ports and same queues of the network, and are treated with a scheduling scheme that guarantees the FIFO property within a queue. Based on this observation, a framework for delay bound guarantee is further proposed, in which the networks with flow aggregates (FAs) scheduling and minimal IRs per FA attached at the network edge are interconnected. The framework guarantees the end-to-end delay bound with reduced complexity, compared to the traditional flow-based approach. Numerical analysis shows that the framework yields smaller bound than both the flow-based frameworks such as the integrated services (IntServ) and the class-based ATS, at least in the networks with identical flows and symmetrical topology.

Abstract:

Based on the extended Environmental Kuznets model (EKC) and the spatial econometric method, this paper analyzes the emission intensity data of water pollution of Chinese provinces and cities from 2004 to 2018 to identify the key factors that could result in water pollution by different periods of time and by different regions as well as to initiate discussions over potential policies to be taken in the future. The results have two implications: on the one hand, water pollution is highly spatially correlated among different Chinese regions and the economic growth indicators such as GDP per capita and the number of lights show an inverted U-shaped nonlinear relationship with the intensity of water pollution emissions. As water pollution demonstrates both leakage effect and spillover effect, it is important to strengthen the implementation strategy featuring comprehensive planning and joint prevention and control. This paper also locates the performance of each region on the EKC curve. As demonstrated in the results, Shanghai, Beijing and Tianjin have become the first ones to manage to cross the inflection point and maintain at this level. Zhejiang, Jiangsu, Shandong and other eastern coastal areas are situated in the peak of the EKC curve, with enormous emission reduction pressure. Most of the provinces in the central region are located at the left side of the peak, and are suffering from serious water pollution resulted from rapid economic growth. Meanwhile, the intensity of water pollution in the western region of China is increasing rapidly. It is integral to seize the opportunity of supply-side reform to speed up the industrial restructuring, and try not to repeat the old lesson of treatment after pollution. In conclusion, it is suggested that governments at all levels should formulate and customize their policies based on their location on the EKC curve, so as to achieve positive dynamics between economic growth and water pollution control.

Abstract:

The design of an IPTV multicast system for the Internet backbone network is presented and explored through extensive simulations. In the proposed system, a resource reservation algorithm such as RSVP, IntServ, or DiffServ is used to reserve resources (i.e., bandwidth and buffer space) in each router in an IP multicast tree. Each router uses an Input-Queued, Output-Queued, or Crosspoint-Queued switch architecture with unity speedup. A recently proposedRecursive Fair Stochastic Matrix Decompositionalgorithm used to compute near-perfect transmission schedules for each IP router. The IPTV traffic is shaped at the sources usingApplication-Specific Token Bucker Traffic Shapers, to limit the burstiness of incoming network traffic. The IPTV traffic is shaped at the destinations usingApplication-Specific Playback Queues, to remove residual network jitter and reconstruct the original bursty IPTV video streams at each destination. All IPTV traffic flows are regenerated at the destinations with essentially zero delay jitter and essentially-perfect QoS. The destination nodes deliver the IPTV streams to the ultimate end users using the same IPTV multicast system over a regional Metropolitan Area Network. It is shown that all IPTV traffic is delivered with essentially-perfect end-to-end QoS, with deterministic bounds on the maximum delay and jitter on each video frame. Detailed simulations of an IPTV distribution system, multicasting several hundred high-definition IPTV video streams over several essentially saturated IP backbone networks are presented.

Full text

Abstract:

Emerging applications such as industrial automation, in-vehicle, professional audio-video, and wide area electrical utility networks require strict bounds on the end-to-end network delay. Solutions so far to such a requirement are either impractical or ineffective. Flow based schedulers suggested in a traditional integrated services (IntServ) framework are O(N) or O(log N), where N is the number of flows in the scheduler, which can grow to tens of thousands in a core router. Due to such complexity, class-based schedulers are adopted in real deployments. The class-based systems, however, cannot provide bounded delays in networks with cycle, since the maximum burst grows infinitely along the cycled path. Attaching a regulator in front of a scheduler to limit the maximum burst is considered as a viable solution. International standards, such as IEEE 802.1 time sensitive network (TSN) and IETF deterministic network (DetNet) are adopting this approach as a standard. The regulator in TSN and DetNet, however, requires flow state information, therefore contradicts to the simple class-based schedulers. This paper suggests non-work conserving fair schedulers, called ‘regulating schedulers’ (RSC), which function as a regulator and a scheduler at the same time. A deficit round-robin (DRR) based RSC, called nw-DRR, is devised and proved to be both a fair scheduler and a regulator. Despite the lower complexity, the input port-based nw-DRR is shown to perform better than the current TSN approach, and to bind the end-to-end delay within a few milliseconds in realistic network scenarios.

Abstract:

ABSTRACT Abdominal pregnancy is a rare event but is associated with significant morbidity and mortality. The incidence of abdominal pregnancy is 1 in 10 000 live births. We report a case on an abdominal pregnancy that presented at 17 weeks of gestation and was not picked up till then on previous ultrasound reports and was eventually diagnosed when presented as missed abortion with placental hemorrhage. The clinical presentation of abdominal pregnancy varies, and the diagnosis depends on a high index of suspicion. Ultrasonography is useful for early diagnosis of the condition. The treatment of the placenta is a matter of controversy. In general, expectant management is suggested. When the placenta is left behind, the use of prophylactic methrotrexate is advocated in some cases although expectant management with serial B-hCG monitoring has also shown to result in subsequent placental shrinkage. An awareness of abdominal pregnancy is very important for reducing associated morbidity and mortality. How to cite this article Ambreen A, Intsar A. Abdominal Ectopic Pregnancy: A Diagnostic Dilemma.

Abstract:

Diatom analysis and radiocarbon dating of the sedimentary cover of the terraces on the South-East coast of Gorlo Strait (White Sea) from Cape Veprevsky to Cape Intsy were carried out for the first time. The Holocene marine sediments traced to 4 m a.s.l. The rise in relative sea level occurred during Boreal and first half of Atlantic. The sea level reached the present value not earlier than 8500 14C yrs BP and probably stabilized at 3,5-4,0 m a.s.l. about 6300 14C yrs BP. The regression of the sea dates approximately 3000 14C yrs BP when coastal sedimentation changed to sediment formation in land environments. Higher levels were formed earlier 9500-8500 14C yrs BP and were not later flooded by the sea according to the diatom analysis data. During the Early Holocene regression, assumptive paleosoil horizons were formed there. They are covered by lacustrine, peaty, and aeolian sediments.

Abstract:

Activating mutations in thyrotropin receptor (TSHR) have been previously described in the context of nonautoimmune hyperthyroidism and thyroid adenomas. We describe, for the first time, a mutation inTSHRcontributing to follicular thyroid carcinoma (FTC) in an adolescent. A 12-year-old girl presented with a right-sided neck swelling, increasing in size over the previous four weeks. Clinical examination revealed a firm, nontender thyroid nodule. Ultrasound scan of the thyroid showed a heterogeneous highly vascular mass. Thyroid function tests showed suppressed TSH [<0.03mU/L], normal FT4 [10.1pmol/L, 9-19], and raised FT3 [9.1pmol/L, 3.6-6.4]. Thyroid [TPO and TRAB] antibodies were negative. A right hemithyroidectomy was performed and the histology of the sample revealed follicular carcinoma with mild to moderate nuclear pleomorphism and evidence of capsular and vascular invasion (pT1b). Sanger sequencing of DNA extracted from the tumour tissue revealed a missense somatic mutation (c.1703T>C, p.Ile568Thr) inTSHR. Papillary thyroid carcinomas constitute the most common thyroid malignancy in childhood, while FTC is rare. FTC due toTSHRmutation suggests an underlying, yet to be explored, molecular pathway leading to the development of malignancy. The case is also unique in that the clinical presentation of FTC as a toxic thyroid nodule has not been previously reported in children.

Abstract:

The use of mediastinal surgery for minimally invasive esophagectomy (MIE) has been proposed; however, this method is not performed as radical surgery because it has been thought to be impossible to perform complete upper mediastinal dissection, including the left tracheobronchial lymph nodes (106tbL). We herein describe a new method for performing complete dissection of the upper mediastinum. We developed a method for performing complete mediastinoscopic esophagectomy as radical surgery via the bilateral transcervical and transhiatal approach in 6 Thiel-embalmed human cadavers. The lower and middle mediastinal lymph nodes are dissected via the transhiatal approach. The dorsal side of the left recurrent nerve is dissected up to the aortic arch and left recurrent nerve lymph nodes (106recL) are dissected under pneumomediastinum. Next, the right recurrent nerve lymph nodes (106recR) are dissected. The cartilage of the left main bronchus is dissected and pushed downward, thereby obtaining a good view between the aortic arch and left main bronchus via the transhiatal approach. The 106tbL lymph nodes are dissected until the aortic arch is reached. Simultaneously, the lymph nodes are dissected via a right cervical incision. This method is termed the “cross-over technique.” We herein demonstrated that the upper mediastinal lymph nodes, including the 106tbL nodes, can be dissected using the bilateral transcervical and transhiatal approach under pneumomediastinum and named this method “mediastinoscopic esophagectomy with lymph node dissection” (MELD). MELD is therefore considered to be a useful modality based on our experience with Thiel-embalmed human cadavers.

Results In this study MVA was 96.5% effective to evacuate the uterus up to 12 weeks gestation while in 3.5% cases procedure failed and further procedure was required to evacuate the uterus. Highest frequency of effectiveness was found in age group of between 15 and 30 years. Primiparous women had highest frequency of effective evacuation. MVA was 100% effective at gestational age between 8 and 10 weeks. Increased BMI was associated with incomplete evacuation. Conclusion The present study shows that MVA is effective method to treat missed miscarriage of less than 12 weeks of gestation. In this study we concluded that there is an association between young patient age, low parity, early gestational age, low BMI and effectiveness of MVA. How to cite this article Ambreen A, Intsar A.

Abstract:

Abstract Repair of contaminated/infected ventral incisional hernias is marked by high rates of recurrence, complications, and/or explantation of synthetic mesh. Biologic mesh products are recommended for repair to permit reconstruction and reduce complications. A systematic review of PubMed, EMBASE, and Cochrane databases identified English-language articles reporting postoperative outcomes (e.g., hernia recurrence, infection, mesh explantation) in patients undergoing contaminated/infected ventral incisional herniorrhaphy. Eleven studies met inclusion criteria and contained quantitative outcome data. All were retrospective chart reviews of biologic mesh use (mostly human acellular dermal matrix). Hernia recurrence and wound infection rates were highly variable and inconsistently reported across studies. Mesh explantation was rarely reported. Outcome variability is likely owing to heterogenous patient populations, surgical technique variations, and follow-up duration. Biologic mesh use in contaminated/infected herniorrhaphy was marked by low reported rates of secondary surgeries for infected mesh removal. Data from large, well-controlled, prospective trials with biologic mesh products are needed.

Abstract:

Abstract An 85-year-old woman with no history of abdominal surgery complained of abdominal pain and vomiting and was referred to us with a diagnosis of intestinal obstruction a few days later. Upon admission to our facility, she presented with marked abdominal swelling and prominent kyphosis. Because of the kyphosis, most of the dilated bowel was compressing her thoracic cavity. No obvious strangulation or free air was observed via abdominal computed tomography imaging. We attempted decompression using a nasogastric tube, but the symptoms persisted. Surgery was performed 2 days after admission. The origin of the obstruction was a compression of the ileocecal region by the costal arch. The bowel was discolored, and thus surgically excised. There were no major postsurgical complications other than a mild wound infection. Until now, there have been no reports of advanced kyphosis inducing ileus, but there are concerns of an increase in similar cases as society continues to age.

Abstract:

Abstract Spinal tuberculosis is the most common manifestation of extrapulmonary tuberculosis. However, there have been few reports on the topic of drug-resistant spinal tuberculosis. The aim of this study was to investigate the efficacy and safety of treatment with a combination of surgery and individual chemotherapy guided by drug susceptibility testing for drug-resistant spinal tuberculosis. We retrospectively analyzed 19 patients with drug-resistant spinal tuberculosis. After surgery, individual chemotherapy was tailored for each patient according to his or her drug resistance profile and previous history of chemotherapy. The patients were followed up clinically and radiologically for an average period of 36 months. Among 19 drug-resistant spinal tuberculosis cases, 16 were multidrug-resistant tuberculosis (MDR-TB), and 3 were non–MDR-TB. The patients with MDR-TB and non–MDR-TB had undergone previous chemotherapy for an average of 12.50 ± 2.00 months (0–55 months) and 5.50 ± 1.20 months (0–60 months), respectively. A total of 16 patients underwent open operations, and the other 3 had percutaneous drainage and local chemotherapy. Patients received individual chemotherapy for an average of 24 months postoperatively. All patients had been cured at the final follow-up. Drug-resistant spinal tuberculosis is mainly acquired through previous irregular chemotherapy and the spread of drug-resistant strains. Treatment with a combination of surgery and individual chemotherapy is feasible in the treatment of severe complications and the prevention of acquired drug resistance.

Abstract:

Abstract Intussusception is a rare cause of adult intestinal obstruction. Clinical manifestations are not specific, which makes a preoperative diagnosis difficult to establish and often causes delay. We report a case of acute intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy was performed revealing an obstructive mass at the ileocecal region resulting from an appendicular tumor. A right hemicolectomy was conducted. The pathologic examination of the resected sample concluded the mass comprised an appendicular mucinous cystoadenoma. We discuss the clinical features, preoperative diagnosis, and surgical strategies of adult intussusception, as well as the uncommon finding of an appendicular mucinous tumor as its causative lesion, with a review of the available literature.

Abstract The aim of this study was to compare the outcomes of the treatment methods of ostomy and primary repair in rectal injuries. A total of 63 patients with rectal injury who had been treated at Dicle University Hospital between 2000 and 2011 were retrospectively reviewed. To determine the outcomes of the treatment methods, the patients were divided into 2 groups (ostomy group: patients who underwent ostomy plus primary repair; repair group: patients who only underwent primary repair) and compared. The patients included 51 men and 12 women. A total of 44 patients underwent ostomy, whereas 19 patients underwent primary repair. No morbidity was detected in either group with grade II intraperitoneal rectal injury. The outcomes of the patients with grade II intraperitoneal and extraperitoneal rectal injury were similar. In the treatment of patients with low-grade rectal injuries, primary repair can be preferred to ostomy.

Abstract:

Abstract The human body's response to surgery is correlated with the extent of tissue damage. The aim of the present study was to, over time, map out parameters concerning inflammation, metabolism, nutrition, breathing function, muscle strength, and well-being in elective colorectal surgery. Eighteen patients were prospectively included: colon resection (n = 9) and rectum resection/amputation (n = 9). Postoperative interleukin 10 (IL-10) rose more in the rectum surgery group on day 0 (P = 0.007) and day 3 (P = 0.025). Furthermore, significant differences between groups were detected regarding albumin, prealbumin, and total iron-binding capacity (TIBC). For albumin and TIBC, this difference was seen even on day 7. C-reactive protein, IL-6, IL-8, glucose, cortisol, insulin, pain, fatigue, nausea, grip strength, and forced expiratory volume in 1 second did not show any differences. No correlation was revealed between measured parameters and postoperative complications. Postoperative levels of IL-10, albumin, prealbumin, and TIBC may be used as determinants of surgical stress after colorectal surgery.

Abstract:

Abstract Endometriosis is an ectopic occurrence of tissue morphologically and functionally resembling endometrial tissue in regions outside the uterine cavity. Although scar endometriosis after surgery has been shown to be most common among all the extrapelvic forms of endometriosis, endometriosis after bladder exstrophy surgery has not been reported, and here we present the first known case. A 26-year-old woman with a history of bladder exstrophy was aware of a painful induration at the operative scar located in the left lower abdominal wall, and presented at our hospital. Although the symptoms resolved, recurring exacerbation was observed after 9 months. Abdominal magnetic resonance imaging showed a heterogeneous mass 16 mm in diameter in the left abdominal wall with high signal intensity on T1W1 and T2W1 images. She underwent excisional biopsy of the lesion under general anesthesia. Histopathology confirmed the diagnosis of endometriosis. Eighteen months after surgery, she was well and free from recurrence.

Abstract:

Abstract Grey relational analysis was used to compare the long-term outcomes of endovascular repair (EVAR) versus open repair for patients with abdominal aortic aneurysm (AAA). Patients with AAA undergoing open repair (n = 133) or EVAR (n = 88) from July 1995 to January 2009 were studied retrospectively. Compared with EVAR, longer periods of postoperative intubation and hospital stay (P < 0.001) were required for open repair. The operation time was significantly longer in open surgery than in EVAR (P < 0.001). Patients in the open repair group required larger volumes of intraoperative blood transfusion than those in EVAR (P < 0.001), and they had more of a trend of cardiac failure after surgery than those in the EVAR group. The operative mortality was similar in both groups. On follow-up, the all-cause mortality and the rates of ischemic legs within 5 years had no significant differences between the 2 procedures (P > 0.05). The grey relational grades in EVAR and open repair were 0.673 and 0.936, respectively. Compared with open repair, patients with AAAs undergoing EVAR had fewer complications in the short term and had a similar all-cause mortality in the long term.

Abstract:

Abstract This report describes a 58-year-old woman with gastric adenocarcinoma and liver metastases, who survives for more than 18 years after diagnosis. At diagnosis and first surgery, a moderately differentiated gastric adenocarcinoma with subserosal invasion was detected, along with 2 regional lymph node metastases and 2 liver metastases. She underwent gastrectomy and regional lymph node dissection but did not undergo liver operation then. After gastrectomy, she received adjuvant chemotherapy for 1 month but discontinued it due to severe diarrhea. Another metastasis in another area of the liver was detected, for which she underwent excision of the right lobe of the liver (subsegments 5, 6, and 7) about 30 months later. No signs of recurrence have been detected for 18 years (as of March 2012). This patient represents a rare case of long-term survival of gastric adenocarcinoma without recurrence after surgical treatment, despite multiple, synchronous, liver and regional lymph node metastases.

Abstract:

Abstract Biliopancreatic diversion (BPD) has excellent results, with the average patient losing 60% to 80% of the excess weight in the first 2 years. However, the BPD works by malabsorption and malabsorptive problems may be experienced with the operation. Therefore, monitoring is necessary for life. In the recent literature there is some debate over the possibility that this technique can increase the risk of colon cancer secondary to the action of the unabsorbed food and bile acid on colonic mucosa. We report the case of a 42-year-old patient with a previous bariatric surgery (BPD with 50 cm common channel; 300 cm alimentary limb) who developed a very aggressive right colon cancer 6 years after the operation. We also review our series of 330 patients operated on during a 14-year period to try to answer if there is any relationship between BPD and colon cancer.

Abstract:

Abstract Metastases to the breast from extramammary tumors are rare. Several clinical, radiologic, and histologic signs can help to distinguish metastases from breast primary tumors. In the present study, we present a case of a left-sided breast metastasis from renal cancer in a 44-year-old woman whose clinical presentation was a mammary nodule in the upper internal quadrant. The patient underwent quadrantectomy with sentinel lymph node biopsy. The histology revealed a clear cell carcinoma. On computed tomography scan a 5×8-cm left renal mass with pulmonary, liver, and intrapericardial nodules was found. The patient underwent palliative care and died after 4 months. Metastasis to the breast is rare, but all of those clinical, radiologic, and histologic signs more typical of extramammary malignancies should always be considered in order to choose the best treatment strategy.

Abstract:

Abstract As there have been many multidrug regimens introduced in colorectal cancer treatment, hypersensitivity is more often encountered than in the past. Though most allergic adverse events of oxaliplatin are mainly classified as type I reaction, a limited number of case reports of type IV reaction (delayed-type hypersensitivity) have been reported. A 73-year-old man was hospitalized for receiving the third cycle of FOLFOX4 plus bevacizumab. Forty-two hours after administration, he had dyspnea and hemoptysis. Acute respiratory distress syndrome was suspected, and the patient underwent mechanical ventilation and steroid pulse therapy. Delayed-type hypersensitivity is induced by induction of inflammation via IL-1, TNF-α and IL-6. The serum level of IL-6 in patients with advanced colorectal cancers is usually greater than the normal range. Therefore, delayed-type hypersensitivity may be easily induced in those patients. We should pay special attention to delayed-type hypersensitivity in advanced colorectal cancer patients undergoing FOLFOX treatment.

Abstract:

Abstract Esophageal submucosal tumors are less common than other gastrointestinal tract tumors. Leiomyoma is the most common benign esophageal SMT, accounting for more than 70% of these tumors. We report on a case of a 56-year-old woman with a 3-cm diameter midthoracic esophageal submucosal tumor. Magnetic resonance imaging suggested leiomyoma or neurofibroma. Video-assisted thoracoscopic surgery was performed to enucleate the tumor from the esophageal wall by splitting the muscle layers. The postoperative course was uneventful, and the patient was discharged on postoperative day 8. Immunohistochemical staining confirmed the diagnosis of esophageal neurofibroma. Gastrointestinal tract involvement of neurofibromatous lesions is rare and occurs most frequently as a systemic manifestation of von Recklinghausen disease. Cases of localized esophageal neurofibroma with prior or subsequent evidence of generalized neurofibromatosis have rarely been documented. This is a rare case of isolated esophageal neurofibroma without classic systemic manifestations of generalized neurofibromatosis, and it is the first reported case treated by video-assisted thoracoscopic surgery.

Abstract:

Abstract The aim of this study was to evaluate the efficacy of vaginal misoprostol for cervical priming at doses of 200 mcg and 400 mcg, 12 to 15 hours before diagnostic office hysteroscopy (OH) without anesthesia in patients with infertility. Sixty infertile patients requiring a diagnostic office hysteroscopy for investigation of infertility were included in the study. The patients were randomly allocated into 3 vaginally administered misoprostol groups: (1) control group, (2) 200-mcg dose group, and (3) 400-mcg dose group. Misoprostol significantly facilitated the procedure of OH: cervical entry was easier; procedural time was shorter; baseline cervical width was larger; and pain scoring was lower in the misoprostol groups compared with the control group. Increasing the dose of misoprostol from 200 mcg to 400 mcg did not improve the effect on cervical dilation. Misoprostol is a promising analog to use for cervical priming before OH. Since doses of 200 mcg and 400 mcg vaginal misoprostol 12 hours before the OH both have proven to be effective regimens, 200 mcg may be preferred. However, before routine clinical usage, further research is needed through large, randomized, controlled trials powered to detect a difference in complications to determine whether misoprostol reduces complications in OH.

Abstract:

Abstract It is unknown whether reduced-port gastrectomy has a less invasive nature than conventional laparoscopy-assisted distal gastrectomy (C-LADG). So we compared 30 cases of dual-port laparoscopy-assisted distal gastrectomy (DP-LADG; using an umbilical port plus a right flank 5-mm port) as a reduced-port gastrectomy with 30 cases of C-LADG alternately performed by a single surgeon. No significant differences were observed in blood loss, intraoperative complications, the number of dissected lymph nodes, postoperative complications, the day of first defecation, analgesic agents required, changes in body temperature, heart rate, white blood cell count, serum albumin level, or lymphocyte count between the 2 groups. The amounts of oral intake in the DP-LADG group were significantly higher on postoperative days 9 and 10. We concluded that the amount of oral intake in the DP-LADG group was superior to that in the C-LADG group; however, no other evidence of DP-LADG being less invasive than C-LADG was obtained.

Abstract:

Abstract Laparoscopic-assisted distal gastrectomy has recently come to be a standard procedure for the treatment of early gastric cancer1–5 in select patients. The minimal invasiveness associated with laparoscopic procedures for the resection of gastrointestinal cancer has been repeatedly explained in part by the short incision that is required.6–11 We used two different approaches to perform distal gastrectomies for the resection of gastric cancer as minimally invasive alternatives to a standard laparoscopic approach prior to our surgical team's complete mastery of the skills required for laparoscopic oncological surgery for gastric cancer.9,12 If the minimal invasiveness associated with laparoscopic-assisted gastrectomy can be explained by the small incision, a gastrectomy via a small incision without the use of a pneumoperitoneum may provide a similar outcome in patients. However, to our knowledge, such a comparison has not been previously made. We compared the minimal invasiveness of three different approaches (minilaparotomy, minilaparotomy approach with laparoscopic assistance, and standard laparoscopic-assisted approach) to performing a distal gastrectomy for T1N0-1 gastric cancer in nonoverweight patients (body mass index, ≤25 kg/m2) performed within a limited study period.

Abstract:

Abstract Incidence of triple-negative breast cancer (TNBC), which is cancer without expression of ER, PgR, and HER2, and nuclear grade (NG) are closely correlated with malignant potential of breast cancer. However, criteria to determine aggressiveness of breast cancer based on these factors have not been elucidated. The aim of this study was to create criteria using these factors to predict tumor recurrence in invasive ductal carcinoma (IDC) of the breast. One hundred and seventy-nine patients with IDC of the breast, which had been treated by surgical resection, were included. One point was added for each factor of the two categories of TNBC and NG 3. The sum of the scores (TGS 0, 1, or 2) was calculated. Significant difference was observed between TGS and the incidence of tumor recurrence (P < 0.0001). Moreover, significant differences were observed regarding relapse-free survival (RFS) between patients with TGS 0 and TGS 1 (P < 0.0001) and patients with TGS 1 and TGS 2 (P = 0.024). TGS might contain a clinical advantage as a useful predictor for tumor recurrence of IDC of the breast and could classify prognosis of the patients with a preferable stratification.

Enhanced computed tomography revealed stenosis of the left branch of the portal vein, obstruction of the right branch of the portal vein at porta hepatis, and esophagogastric varices. Balloon angioplasty of the left branch of the portal vein under transsuperior mesenteric venous portography was performed by minilaparotomy. After dilatation of the left branch of the portal vein, the narrow segment of the portal vein was dilated, which resulted in reduction of collateral circulation. At 7 days after balloon angioplasty, esophageal varices were improved. The patient made a satisfactory recovery, was discharged 8 days after balloon angioplasty, and remains well.

Abstract A 41-year-old male patient with hepatitis B underwent right tri-segmentectomy and total caudate lobectomy for a huge hepatocellular carcinoma associated with complete occlusion of the inferior vena cava with thrombosis of the infrahepatic inferior vena cava due to tumor compression. Five months later, he was readmitted for ascites and hyperbilirubinemia. Venography revealed stenosis and tortuosity of the left hepatic vein and the inferior vena cava, for which balloon angioplasty of the left hepatic vein and the inferior vena cava was performed using an 8-mm and 10-mm balloon, respectively. The left hepatic venous pressure decreased from 65 mmHg to 25 mmHg after dilatation. The patient made a satisfactory recovery thereafter and remains well with normal liver functions and without ascites. Balloon angioplasty may be useful for liver failure due to hepatic vein stenosis after hepatic resection.
