    ABSTRACT Aberrant right subclavian artery-esophageal fistula is a rare but potentially fatal complication. It may be associated with procedures, such as tracheostomy and tracheal or esophageal intubation, and yields massive upper gastrointestinal bleeding difficult to identify and to control. A high index of suspicion is essential for early diagnosis and better prognosis. We report a rare case of a patient who survived after emergent surgical procedure for massive upper gastrointestinal bleed...

    A subclavian artery-esophageal fistula usually occurs on the right side of an aberrant subclavian artery. It also rarely appears in the site between a non-aberrant subclavian artery and the esophagus due to the ingestion of a foreign body. Upper gastrointestinal bleeding in the case of a subclavian artery-esophageal fistula is rare but often fatal. Here, we report on a 62-year-old male patient with a left subclavian arteryesophageal fistula complicated by hemorrhagic shock. He swallowed a for...

    Percutaneous transluminal angioplasty and stent placement is now an established treatment option for chronic mesenteric ischemia and is associated with low mortality and morbidity rates. We present a case of reperfusion hemorrhage complicating endovascular repair of superior mesenteric artery stenosis. Although a recognized complication following repair of carotid stenosis, hemorrhage has not previously been reported following mesenteric endovascular reperfusion. We describe both spontaneous cessation of bleeding and treatment with coil embolization.

    @@ Massive hemorrhage from infected anastomosed site between the graft artery and the external iliac artery is one of the most serious complications of renal transplantation. Clinically, it is a rare but fatal occasion. We reported here one case of hemorrhage with infection in the iliac artery anastomosed site treated successfully with hypogastric artery autograft interposition in March 2003.

  5. Study of Controlling Acute Hemorrhage from Esophageal Varices Rupture with Technique of Traditional Chinese Medicine

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Objective: To find a method for inducing Chinese drugs to adhere to the esophageal mucosa to control bleeding from ruptured esophageal varices. Methods: The site and time that the Chinese drugs adhere to esophageal mucosa were observed in 30 healthy volunteers under the specific condition of standing and lying posture. Seventy episodes bled with ruptured esophageal varices patients (treated group 36 episodes in 25 patients and control group 34 episodes in 27 patients) suffering from cirrhosis of liver were treated by the technique of drug adhesion. Results: (1) The adhesion of Chinese hemostatic drugs remained in the lower segment of esophagus for more than 15 minutes in lying posture, longer than that in standing posture (P0.05). Conclusion: This drug adhesion technique provides a new approach to control hemorrhage from ruptured esophageal varices.

    To evaluate the clinical efficacy and safety of a transcatheter arterial embolization (TAE) with N-butyl cyanoacrylate (NBCA) for the treatment of arterial esophageal bleeding. Between August 2000 and April 2008, five patients diagnosed with arterial esophageal bleeding by conventional angiography, CT angiography or endoscopy, underwent a TAE with NBCA. We mixed NBCA with iodized oil at ratios of 1:1 to 1:4 to supply radiopacity and achieve a proper polymerization time. After embolization, we evaluated the angiographic and clinical success, recurrent bleeding, and procedure-related complications. The bleeding esophageal artery directly originated from the aorta in four patients and from the left inferior phrenic artery in one patient. Although four patients had an underlying coagulopathy at the time of the TAE, angiographic and clinical success was achieved in all five patients. In addition, no procedurerelated complications such as esophageal infarction were observed during this study. NBCA can be an effective and feasible embolic agent in patients with active arterial esophageal bleeding, even with pre-existing coagulopathy.

    The purpose of this study is to identify the characteristics of brain perfusion measured by arterial spin-labeling magnetic resonance imaging (ASL-MRI) in cerebral hemorrhages. Brain blood flow values (CBF-ASL values) for cerebral and cerebellar hemispheres and segmented cerebral regions were measured by ASL-MRI in 19 putaminal hemorrhage patients and 20 thalamic hemorrhage patients in acute or subacute stages. We assessed the lateralities of CBF-ASL values and the relationships between CBF-ASL values and other imaging findings and clinical manifestations. Both the 19 putaminal hemorrhage patients and the 20 thalamic hemorrhage patients had significantly low CBF-ASL values of the contralateral cerebellum in subacute stage, suggesting that ASL-MRI might delineate crossed cerebellar diaschisis (CCD). Ipsilateral low CBF-ASL values were observed in frontal lobes and thalami with a putaminal hemorrhage and lentiform nuclei, temporal lobes, and parietal lobes with a thalamic hemorrhage, suggesting that ASL-MRI showed the ipsilateral cerebral diaschisis (ICD). In the putaminal hemorrhage patients, the hematoma volume negatively affected both the bilateral cerebellar and cerebral hemispheric CBF-ASL values. In the thalamic hemorrhage patients, a concomitant intraventricular hemorrhage caused low cerebral hemispheric CBF-ASL values. The use of ASL-MRI is sensitive to the perfusion abnormalities and could thus be helpful to estimate functional abnormalities in cerebral hemorrhage patients. (orig.)

    The aims of this study were to identify arteriographic manifestations of acute renal hemorrhage and to evaluate the efficacy of emergency embolization. Emergency renal artery angiography was performed on 83 patients with acute renal hemorrhage. As soon as bleeding arteries were identified, emergency embolization was performed using gelatin sponge, polyvinyl alcohol particles, and coils. The arteriographic presentation and the effect of the treatment for acute renal hemorrhage were analyzed retrospectively. Contrast extravasation was observed in 41 patients. Renal arteriovenous fistulas were found in 12 of the 41 patients. In all, 8 other patients had a renal pseudoaneurysm, 5 had pseudoaneurysm rupture complicated by a renal arteriovenous fistula, and 1 had pseudoaneurysm rupture complicated by a renal artery-calyceal fistula. Another 16 patients had tumor vasculature seen on arteriography. Before the procedure, 35 patients underwent renal artery computed tomography angiography (CTA). Following emergency embolization, complete hemostasis was achieved in 80 patients, although persistent hematuria was present in 3 renal trauma patients and 1 patient who had undergone percutaneous nephrolithotomy (justifying surgical removal of the ipsilateral kidney in this patient). Two-year follow-up revealed an overall effective rate of 95.18 % (79/83) for emergency embolization. There were no serious complications. Emergency embolization is a safe, effective, minimally invasive treatment for renal hemorrhage. Because of the diversified arteriographic presentation of acute renal hemorrhage, proper selection of the embolic agent is a key to successful hemostasis. Preoperative renal CTA plays an important role in diagnosing and localizing the bleeding artery.

    A retrospective evaluation of embolotherapy in patients with arterial liver hemorrhages was carried out. Twenty-six patients, ranging in age from 10 days to 77 years with active arterial liver hemorrhages, underwent non-surgical embolotherapy. Bleeding was attributed to trauma (n = 21), tumor (n = 3), pancreatitis (n = 1), or unknown cause (n = 1). Twenty-nine embolizations were performed via a transfemoral (n = 26) or biliary (n = 2) approach. One bare Wallstent was placed into the common hepatic artery via to an axillary route to cover a false aneurysm due to pancreatitis. Treatment was controlled in 4 patients by cholangioscopy (n = 2) or by intravascular ultrasound (n = 2). Prior surgery had failed in 3 patients. Intervention controlled the hemorrhage in 24 of 26 (92 %) patients within 24 h. Embolotherapy failed in 1 patient with pancreatic carcinoma and occlusion of the portal vein. In 1 patient with an aneurysm of the hepatic artery treated by Wallstent insertion, total occlusion was not achieved in the following days, as demonstrated by CT and angiography. However, colour Doppler flow examination showed no flow in the aneurysm 6 months later. Complications were one liver abscess, treated successfully by percutaneous drainage for 10 days, and one gallbladder necrosis after superselective embolization of the cystic artery. Embolization is a effective tool with a low complication rate in the treatment of liver artery hemorrhage, even in patients in whom surgery has failed. (orig.) (orig.) With 2 figs., 26 refs.

    Full Text Available Background: Some complications related to vertebral artery occlusion by endovascular technique have been reported. However, cerebellar hemorrhage after vertebral artery occlusion in subacute phase is rare. In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive therapy for vasospasm after embolization of a vertebral dissecting aneurysm. Case Description: A 56-year-old female with a ruptured vertebral dissecting aneurysm proximal to the posterior inferior cerebellar artery developed cerebellar hemorrhage 15 days after embolization of the vertebral artery, including the dissected site. In this patient, the preserved posterior inferior cerebellar artery fed by retrograde blood flow might have been hemodynamically stressed during hypertensive and antiplatelet therapies for subarachnoid hemorrhage, resulting in cerebellar hemorrhage. Conclusion: Although cerebellar hemorrhage is not prone to occur in the nonacute stage of embolization of the vertebral artery, it should be taken into consideration that cerebellar hemorrhage may occur during hypertensive treatment.

    Full Text Available Bleeding complications of dengue hemorrhagic fever such as epistaxis, gum bleeding, gastrointestinal bleeding, hypermenorrhea, hematuria, and thrombocytopenia have been documented. A 49-year-old female presented with complaints of intermittent high-grade fever for the past 4 days, lower abdominal pain and altered sensorium for 1 day. Laboratory investigations revealed severe anemia, mild thrombocytopenia, hypofibrinogenemia, and positive dengue serology. Emergency ultrasound examination of the abdomen revealed a possible rapidly expanding hematoma from the inferior epigastric artery and suggested urgent computed tomography (CT angiogram for confirmation of the same. CT angiogram was confirmatory, and patient underwent emergency embolization of the right inferior epigastric artery. We report the first case of inferior epigastric hemorrhage and rectus sheath hematoma as a consequence of dengue.

    Full Text Available Hemorrhage in pregnancy is the leading cause of maternal mortality in developing countries. Internaliliac artery ligation is one of the life saving procedures in intractable pelvic hemorrhage. Althougheffective, the procedure is not commonly performed by obstetricians and gynecologists. Present paper aims at sharing author’s experience about usefulness of this surgical procedure in arrest of pelvic hemorrhage and to remove the inhibition among practicing gynecologists regarding this procedure.Fifty four cases of pelvic hemorrhage were managed by internal iliac artery ligation over 15 year period at tertiary care center. Hemorrhage could be arrested in all cases.

    Aneurysms of the external carotid artery can be causally for threatening late hemorrhage secondary to tonsillectomy. On the bases of typical, extended and finally dramatic bleeding course in a child the "clinical look" and the sensitivity should be raised for this bleeding cause. Characteristic after apparently inconspicuous post-operative first phase is late signal bleeding with little loss of blood which are replaced after following intervals free of bleeding from bleeding as flood with massive loss of blood. Then vessel-imaging (Angio-MRI or CT) is urgently indicated. By confirmation of the suspicion diagnosis the interventional angiography is the therapy of the choice, although after successful embolisation a fine-meshed postcontrol is necessary, because therapy failures are possible how the described case points. The highest security offers the surgical exploration with aimed vessel stopping.

    In patients with upper gastrointestinal bleeding (UGIB), identifying those with esophageal variceal hemorrhage prior to endoscopy would be clinically useful. This retrospective study of a large cohort of patients with UGIB used logistic regression analyses to evaluate the platelet count, aspartate aminotransferase (AST) to platelet ratio index (APRI), AST to alanine aminotransferase (ALT) ratio (AAR) and Lok index (all non-invasive blood markers) as predictors of variceal bleeding in (1) all patients with UGIB and (2) patients with cirrhosis and UGIB. 2233 patients admitted for UGIB were identified; 1034 patients had cirrhosis (46%) and of these, 555 patients (54%) had acute UGIB due to esophageal varices. In all patients with UGIB, the platelet count (cut-off 122,000/mm(3)), APRI (cut-off 5.1), AAR (cut-off 2.8) and Lok index (cut-off 0.9) had area under the curve (AUC)s of 0.80 0.82, 0.64, and 0.80, respectively, for predicting the presence of varices prior to endoscopy. To predict varices as the culprit of bleeding, the platelet count (cut-off 69,000), APRI (cut-off 2.6), AAR (cut-off 2.5) and Lok Index (0.90) had AUCs of 0.76, 0.77, 0.57 and 0.73, respectively. Finally, in patients with cirrhosis and UGIB, logistic regression was unable to identify optimal cut-off values useful for predicting varices as the culprit bleeding lesion for any of the non-invasive markers studied. For all patients with UGIB, non-invasive markers appear to differentiate patients with varices from those without varices and to identify those with a variceal culprit lesion. However, these markers could not distinguish between a variceal culprit and other lesions in patients with cirrhosis.

    Objective: To study the correlation between changes in portosystemic collaterals, evaluated by multidetector-row computed tomography imaging using multiplanar reconstruction (MDCT-MPR), and prognosis in patients with hemorrhagic esophageal varices (EV) after endoscopic treatment. Methods: Forty-nine patients with primary hemostasis for variceal bleeding received radical endoscopic treatment: endoscopic injection sclerotherapy (EIS) or endoscopic variceal ligation (EVL). Patients were classified according to the rate of reduction in feeding vessel diameter on MDCT-MPR images, into the narrowing (n = 24) and no-change (n = 25) groups. We evaluated changes in portosystemic collaterals by MDCT-MPR before and after treatment, and determined rebleeding and survival rates. Results: The left gastric and paraesophageal (PEV) veins were recognized as portosystemic collaterals in 100 and 80%, respectively, of patients with EV on MDCT-MPR images. The rebleeding rates at 1, 2, 3, and 5 years after endoscopic treatment were 10, 15, 23, and 23%, respectively, for the narrowing group, and 17, 24, 35, and 67%, respectively, for the no-change group (P = 0.068). Among no-change group, the rebleeding rate in patients with large PEV was significantly lower than that with small PEV (P = 0.027). The rebleeding rate in patients with small PEV of the no-change group was significantly higher than that in the narrowing group (P = 0.018). There was no significant difference in rebleeding rates between the no-change group with a large PEV and narrowing group (P = 0.435). Conclusion: Changes in portosystemic collaterals evaluated by MDCT-MPR imaging correlate with rebleeding rate. Evaluation of portosystemic collaterals in this manner would provide useful information for the management of hemorrhagic EV.

    Purpose: To determine whether transcatheter arterial embolization performed in the setting of active gastric or duodenal nonvariceal hemorrhage is efficacious when the bleeding source cannot be identified angiographically. Methods: Records of 115 adult patients who underwent visceral angiography for endoscopically documented gastric (50 patients) or duodenal (65 patients) nonvariceal hemorrhage were retrospectively reviewed. Patients were subdivided into three groups according to whether angiographic evidence of arterial hemorrhage was present and whether embolization was performed (group 1 = no abnormality, no embolization; group 2 = no abnormality, embolization performed [empiric embolization]; and group 3 = abnormality present, embolization performed). Thirty-day rates and duration of primary hemostasis and survival were compared.ResultsFor patients with gastric sources of hemorrhage, the rate of primary hemostasis at 30 days after embolization was greater when embolization was performed in the setting of a documented angiographic abnormality than when empiric embolization was performed (67% vs. 42%). The rate of primary hemostasis at 30 days after angiography was greater for patients with duodenal bleeding who either underwent empiric embolization (60%) or embolization in the setting of angiographically documented arterial hemorrhage (58%) compared with patients who only underwent diagnostic angiogram (33%). Patients with duodenal hemorrhage who underwent embolization were less likely to require additional invasive procedures to control rebleeding (p = 0.006). Conclusion: Empiric arterial embolization may be advantageous in patients with a duodenal source of hemorrhage but not in patients with gastric hemorrhage.

    We tried transcatheter arterial embolization for lower gastrointestinal hemorrhage due to radiation colitis. In this case, colostomy and endoscopic therapy were not effective. We succeeded in arresting the hemorrhage without any complications. Transcatheter embolization is a low-invasive and safe method of treatment. For prevention of inflammation and iatrogenic abscess formation, we repeated this therapy and we tried arterial injection of antibiotics and steroid. And so, this therapy is one of the effective methods. (author)

    Full Text Available Postpartum hemorrhage is a major cause of maternal mortality. Though uncommon, uterine artery pseudoaneurysm can follow uterine dilatation and curettage (D + C and needs to be considered in the differential diagnosis. This 30-year-old G1P1 woman presented with right upper quadrant pain and vaginal bleeding. She was afebrile but her white blood count was significantly increased (22.2×109 /L. One week prior, she had undergone a Cesarean delivery which was complicated by hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP, fetal dystocia, and chorioamnionitis. Uterine dilatation and curettage (D & C and placement of a Bakri intrauterine balloon, performed for suspected retained products of conception, failed to control her postpartum bleeding. The patient wished to have a hysterectomy only as a last resort in order to preserve fertility. Emergency uterine artery angiography revealed a left uterine artery pseudoaneurysm and contrast extravasation. The patient was successfully treated with selective embolization. Computed tomography (CT later revealed dehiscence of her uterine Cesarean section incision with an intra-abdominal fluid collection. This collection was drained. She also developed disseminated intravascular coagulopathy (DIC syndrome as well as multiple pulmonary emboli which were both successfully treated. We discuss this unique case of uterine artery pseudoaneurysm with associated uterine dehiscence.

    To evaluate the safety and clinical efficacy of transcatheter uterine artery embolization (UAE) for post-myomectomy hemorrhage. We identified eight female patients (age ranged from 29 to 51 years and with a median age of 37) in two regional hospitals who suffered from post-myomectomy hemorrhage requiring UAE during the time period from 2004 to 2012. A retrospective review of the patients' clinical data, uterine artery angiographic findings, embolization details, and clinical outcomes was conducted. The pelvic angiography findings were as follows: hypervascular staining without bleeding focus (n = 5); active contrast extravasation from the uterine artery (n = 2); and pseudoaneurysm in the uterus (n = 1). Gelatin sponge particle was used in bilateral uterine arteries of all eight patients, acting as an empirical or therapeutic embolization agent for the various angiographic findings. N-butyl-2-cyanoacrylate was administered to the target bleeding uterine arteries in the two patients with active contrast extravasation. Technical and clinical success were achieved in all patients (100%) with bleeding cessation and no further related surgical intervention or embolization procedure was required for hemorrhage control. Uterine artery dissection occurred in one patient as a minor complication. Normal menstrual cycles were restored in all patients. Uterine artery embolization is a safe, minimally invasive, and effective management option for controlling post-myomectomy hemorrhage without the need for hysterectomy.

    Conclusions: Anterior cervical spine surgery is a safe approach and is associated with few major esophageal/pharyngeal complications, which most commonly include transient dysphagia and dysphonia. If symptoms persist, patients should be assessed for esophageal/pharyngeal defects utilizing appropriate imaging studies. Notably, even if the major complications listed above are adequately treated, optimal results are in no way guaranteed.

    Full Text Available Abstract Aberrant right subclavian artery (ARSA is asymptomatic in most cases. This variant anatomy can cause dysphagia in elderly patients. Impaction of foreign body in the esophagus is rarely the presenting symptom of ARSA. We present an eighty four years old patient who first presented with esophageal foreign body impaction and was diagnosed with an aberrant right subclavian artery compressing the esophagus just below the site of impaction. We assume that the exact place of impaction was not incidental and that a relative narrowing of the esophagus caused by the vascular anomaly is responsible for this specific presentation.

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

    Percutaneous liver biopsy is considered one of the most important diagnostic tools to evaluate diffuse liver diseases. Pseudoaneurysm of hepatic artery is an unusual complication after ultrasound-guided percutaneous liver biopsy. Delayed hemorrhage occurs much less frequently. We report a case of pseudoaneurysm of the hepatic artery of a 46-year-old man who was admitted for abdominal pain after 4 d of liver biopsy. The bleeding was controlled initially by angiographic embolization.However, recurrent bleeding could not be controlled by repeat angiography, and the patient died 4 d after admission from multiorgan failure. The admittedly rare possibility of delayed hemorrhage should be considered whenever a liver biopsy is performed.

Case report A sixty-nineyear- old man suffering from pancreatic head carcinoma underwent pancreatoduodenectomy. On the 12th postoperative day he developed melena. Endoscopic evaluation revealed occult bleeding coming from the afferent limb of the gastro-jejunal anastomosis. The patient was treated conservatively. On the 15th postoperative day the patient presented a new episode of melena and hematemesis. Upper abdominal series control by computer tomography, selective angiography of the celiac trunk and superior mesenteric artery set the diagnosis of a pseudoaneurysm of the gastro-duodenal arterial stump. The patient was managed by trans-catheter arterial embolization and complete hemostasis was achieved. Conclusion Delayed intraluminal hemorrhage after pancreatoduodenectomy may be caused after pseudoaneurysm due to some visceral arterial stem erosion. Initial management, both diagnostic and therapeutic, should be the angiographic control and trans-catheter embolization of the bleeding vessel. In case of hemodynamic instability or when angiographic embolism is unsuccessful reoperation is the proper treatment.

    OBJECTIVE To evaluate how arterial infusion chemotherapy after radical surgery influences long-term survival of patients with pathologic T3 (pT3) esophageal squamous carcinoma.METHODS We divided 190 patients with pathologic pT3 esophageal squamous carcinoma, confirmed by consecutive radical surgery, into an experimental group (surgery + intra-arterial infusion, 56 T3N0M0 and 52 T3N1M0 cases), and the remaining patients into a control group (surgery alone, 48 T3N0M0 and 34 T3N1M0 cases). The experimental group was sub-grouped into 56 cases (26 T3N0M0 and 30 T3N1M0 cases) receiving 1 or 2 periods of chemotherapy, while 52 cases (30 T3N0M0 and 22 T3N1M0 cases) underwent 3 or more than 3 periods of chemotherapy. We used one to seven courses of selected arterial infusion chemotherapy of cisplatin (80 mg/m2 of body-surface area) and fluorouracil (800 mg/m2) with or without epirubicin at 3~4 weeks post operation. The interval between each period was 3~4 weeks. All cases were followed-up for more than 5 years. Survival rates were calculated by the Kaplan-Meier methods and survival differences between patients with and without selected arterial infusion chemotherapy were compared with the Log-rank test. Prognostic variables were entered into a Cox regression analysis model controlling for age, site, lymph node status, and treatment received.RESULTS The overall survival rates were not significantly different between the experimental group and the control group, but there was better survival for patients who received 3 or more than 3 courses of chemotherapy. Lymph node status (N) was an important factor in the prognosis.CONCLUSION Trans-catheter arterial infusion chemotherapy is a safe and effective method of therapy. Postoperative selective arterial infusion chemotherapy can improve the survival rate in patients with esophageal squamous carcinoma who were previously treated by radical surgery.However, this modality of therapy needs further investigation.

    To assess the difference between carotid haemorrhagic plaque and non-haemorrhagic plaque by using diffusion-weighted imaging (DWI) and to evaluate carotid intraplaque haemorrhage (IPH) and intramural hematoma (IMH) of cervical artery dissection with apparent diffusion coefficient (ADC) measurement. Fifty-one symptomatic patients underwent 3.0-T carotid MR imaging, including conventional sequences, three-dimensional (3D) magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequence, and DWI. Thirty-nine patients with carotid plaque and eight patients with IMH of cervical artery dissection were finally included. The groups of hemorrhagic plaque, non-hemorrhagic plaque and IMH were divided according to 3D MPRAGE sequence. ADC values of different groups were measured, and t tests were performed. The mean ADC values of hemorrhagic plaques, non-hemorrhagic plaque and IMH were (1.284 ± 0.327) x 10{sup -3}mm{sup 2}/s, (1.766 ± 0.477) x 10{sup -3}mm{sup 2}/s, and (0.563 ± 0.119) x 10{sup -3}mm{sup 2}/s, respectively. The mean ADC values of hemorrhagic and non-hemorrhagic regions in the hemorrhagic plaque group were (0.985 ± 0.376) x 10{sup -3}mm{sup 2}/s and (1.480 ± 0.465) x 10{sup -3}mm{sup 2}/s, respectively. The differences between the hemorrhagic plaque and non-hemorrhagic plaque, hemorrhagic region and non-hemorrhagic region in hemorrhagic plaque, and the hemorrhagic region in the hemorrhagic plaque and IMH of artery dissection were significant (P < 0.05). DWI may be a useful complement to conventional MR imaging for identifying haemorrhage of carotid plaques and differentiate IMHs from IPH. (orig.)

    AIM: To examine the effects of opioid receptor antagonists and norepinephrine on intracellular free Ca2+ concentration ([Ca2+]i) in mesenteric arterial (MA) smooth muscle cells (SMC) isolated from normal and hemorrhagic shocked rats in the vascular hyporesponse stage. METHODS: The rat model of hemorrhagic shock was made by withdrawing blood to decrease the artery mean blood pressure to 3.73-4.26 kPa and keeping at the level for 3 h.[Ca2+]i of vascular smooth muscle cells (VSMC) were detected by the laser scan confocal microscopy. RESULTS:In the hyporesponse VMSC of rats in hemorrhagic shock, selective δ-, κ-, and μ-opioid receptor antagonists (naltrindole, nor-binaltorphimine, and β-funaltrexamine, 100 nmol/L) as well as norepinephrine 5 μmol/L significantly increased [Ca2+]i by 47 %±13 %, 37 %±14 %, 33 %±10 %, and 54 %±17 %, respectively, although their effects were lower than those in the normal rat cells (the increased values were 148 %±54 %, 130 %±44 %, 63 %±17 %and 110 %±38 %, respectively); and the norepinephrine-induced increase in [Ca2+]i was further augmented by three δ-, κ-, and μ-opioid receptor antagonists (50 nmol/L, respectively) application (from 52 %± 16 % to 99 %±29 %,146 %±54 % and 137 %±47 %, respectively). CONCLUSION: The disorder of [Ca2+]i regulation induced by hemorrhagic shock was mediated by opioid receptor and α-adrenoceptor, which may be partly responsible for the vascular hyporesponse, and the opioid receptor antagonists improved the response of resistance arteries to vascular stimulants in decompensatory stage of hemorrhagic shock.

    2015-04-01

    Full Text Available Splenic artery pseudoaneurysms are infrequently encountered but critical to recognize. Limited literature to date describes associations with pancreatitis, trauma, and rarely peptic ulcer disease. Hemorrhage and abdominal pain are the most common manifestations. There is typically overt gastrointestinal blood loss but bleeding can also extend into the peritoneum, retroperitoneum, adjacent organs, or even a pseudocyst. Most patients with ruptured splenic artery pseudoaneurysms present with hemodynamic instability. Here, we describe a patient recovering from acute illness in the intensive care unit but with otherwise no obvious risk factors or precipitants for visceral pseudoaneurysm. He presented with acute onset altered mental status, nausea, and worsening back and abdominal pain and was found to be in hypovolemic shock. The patient was urgently stabilized until more detailed imaging could be performed, which ultimately revealed the source of blood loss and explained his rapid decompensation. He was successfully treated with arterial coiling and embolization. Thus, we herein emphasize the importance of prompt recognition of hemorrhagic shock and of aggressive hemodynamic stabilization, as well as a focused diagnostic approach to this problem with specific treatment for splenic artery pseudoaneurysm. Finally, we recommend that multidisciplinary management should be the standard approach in all patients with splenic artery pseudoaneurysm.

    Basilar artery dissection (BAD) is a rare condition with a worse prognosis than a dissection limited to the vertebral artery. We report a rare case of chronic BAD with an associated symptomatic aneurysm presenting with massive subarachnoid hemorrhage (SAH) in a 54-year-old woman. The diagnosis of acute BAD could only be made retrospectively, based on clinical and neuroradiological studies from a hospital admission 10months earlier. Angiography performed after her SAH showed unequivocal signs of imperfect healing; she was either post-recanalization of a complete occlusion or post-dissection. Residual multi-channel intraluminal defects led to the development of a small aneurysm, which was responsible for the massive hemorrhage. The occurrence of an associated aneurysm, and wall disease, but not an intraluminal process, reinforces the diagnosis of dissection. The patient was fully recovered at 90day follow-up. This case reinforces the need for long-term neuroradiological surveillance after non-hemorrhagic intracranial dissections to detect the development of de novo aneurysms.

    We evaluated the efficacy and predictors of clinical outcome after transcatheter arterial embolization (TAE) for treatment of postpartum hemorrhage with disseminated intravascular coagulation (DIC). Of 127 patients who underwent TAE for postpartum hemorrhage, 46 progressed to DIC (group 1), 81 showed normal range hematological parameters (group 2). We retrospectively evaluated etiology, embolization methods and the efficacy of TAE for intergroup comparison Pearson Chi-Square test and logistic regression model. Overall TAE failed to control bleeding in 9 patients in spite of technical success. Lower bleeding control rate was found in group 2 (82.6%) relative to group 1 (98.8%, p = 0.001). And embolization methods were not statistically different between two groups no statistically significant predictors associated with failed hemostasis except the amount of transfusion in group 1. Although bleeding control rate is lower in postpartum hemorrhage with DIC than without DIC, we believe that TAE with correction of DIC is an effective method for postpartum hemorrhage with DIC.

    When a large visceral artery is ruptured,uncontrolled bleeding may lead to hemodynamic collapse.Use of endovascular occlusion balloon catheter may provide rapid control of hemorrhage and facilitate definitive therapy.We reported two patients with massive hemorrhage from ruptured celiac-hepatic artery after pancreaticoduodenectomy,who were initially treated percutaneously by temporary selective balloon occlusion.They became critically hemodynamic unstable during the angiographic procedure.Through an 8Fr sheath,a 6Fr compliant latex occlusion balloon was placed proximal to the celiac trunk and inflated,and upon patient stabilization surgical revision and stent-graft placement were successfully performed in the two patients,respectively.Temporary selective balloon occlusion provides fast and effective bleeding control for patient with critically uncontrollable visceral arterial hemorrhage,permitting subsequent use of conventional techniques for management of the arterial bleeding source.

    Full Text Available Context Segmental arterial mediolysis is an uncommon, non-atherosclerotic, non-inflammatory arteriopathy that involvesareas of dissecting aneurysms and strictures that are caused by outer media lysis of the arterial wall from areas of medialnecrosis of uncertain pathogenesis. It has a predilection for splanchnic arteries and often presents as abdominal pain orhemorrhage in late middle-aged and elderly patients. Diagnosis can be established by computed tomography angiography,magnetic resonance angiography, or angiogram by visualizing typical abnormalities, in addition to excluding othervasculitides. Histological confirmation is the gold standard but is not easily accessible and, as such, is not frequentlyperformed. Case report Here we present an updated review of the literature and a case of segmental arterial mediolysis thatpresented with spontaneous intra-abdominal bleeding near the pancreas that was originally misdiagnosed as hemorrhagicpancreatitis. Conclusion Diagnosis is important because immunosuppressants for vasculitis can worsen the arteriopathy.Segmental arterial mediolysis can be self-limiting without treatment or may require urgent surgical or endovascular therapyfor bleeding and carries a 50% mortality rate. Therefore, it should be included in the differential of causes of abdominal painas well as in cases of unexplained abdominal hemorrhage.

    Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility. Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.

    ástrica esquerda ocluída e veia gástrica esquerda não-opacificada.OBJECTIVE: To standardize the treatment recurrent hemorrhage esophageal varices in schistosomotic patients after non decompressive surgery. METHODS: We treated 45 patients with schistosomotic portal hypertension who presented recurrent hemorrhage esophageal varices. Performance of abdominal ultra-sonography and arteriographic studies and two groups were defined: Group A: Nineteen patients (42,2% with absence of spleen, occluded splenic artery and patency of left gastric artery and vein, thus characterizing splenectomy at prior operation. Group B: Twenty six patients (57,8% with absence of spleen image, occluded splenic and left gastric artery and non-opacified left gastric vein, showing splenectomy and some type of gastroesophageal devascularization performed before. Patients of Group A were reoperated to carry out the gastroesophageal devascularization and patients of Group B were submitted to a sclerotherapy program. RESULTS: In Group A, one patient (5.3% presented recurrent hemorrhage on the late postoperative period. The esophageal varices decreased in number or diameter in 14 patients (73.7%, disappeared in three (15.8% and remained unchanged in two (10.5%, under final endoscopic evaluation. In Group B, six patients (23.1% presented recurrent bleeding. In four patients the acute hemorrhagic event were controlled. Two patients who underwent mesocaval shunt owing to unsuccess of these methods died postoperatively. Esophageal varices disappeared in 17 patients (65.4%, decreased in number or diameter in seven (26.9% and remained unchanged in two (7.7% after the last endoscopic evaluation. CONCLUSIONS: 1 The gastroesophageal devascularization is appropriated to splenectomized patients, with patency of left gastric artery and vein. 2 A long term of esophageal varices endoscopic sclerotherapy may be an option to splenectomized patients, with occluded left gastric artery and non-opacified left gastric ven.

    This study was conducted to investigate the effect of uterine artery embolization for the treatment of hemorrhage following second-trimester labor induction for women with scarred uterus. Two cases of second-trimester abortion were retrospectively reviewed, both of which had a history of caesarean delivery and were complicated by gestational anemia. One was at 18 weeks' gestation and presented with persistent vaginal bleeding for two months resulting in relatively large area of blood clot in uterine cavity. The other was at 25 weeks' gestation with partial hydatidiform mole and presented with intermittent vaginal bleeding. Both patients presented with continuous and heavy vaginal bleeding after oral administration of mifepristone for labor induction, with one cervix left unopened, while the other cervix 3 cm left dilatation, yet felt obstructed by pregnant tissue. Both patients were immediately treated with uterine artery embolization (UAE). Both patients presented with alleviated hemorrhage and regular uterine contraction after UAE, followed by smooth induction of labor. No hemorrhage occurred since then during the follow-up. The results suggest that UAE is safe and effective for the treatment of massive hemorrhage of second-trimester abortion in women with scarred uterus. It can reduce time period of labor induction and alleviate hemorrhage, which not only rescues patients but also avoids cesarean sections and retains fertility for the pregnant.

    Spinal injury following inertial loading of the head and neck (whiplash) is a common sequel of low speed traffic crashes. A variety of non-musculoskeletal injuries have been described in association with injury to the spine following whiplash trauma, including traumatic brain injury, vestibular derangement, and cranial nerve injury, among others. Vascular injuries in the head and neck have, however, only rarely been described. We present the case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery (ICA) and intracerebral vascular structures following a hard braking maneuver, with no direct head- or neck contact with the vehicular interior. Based on this unusual mechanism of injury we reviewed hospital data from the United States nationwide inpatient database (NIS) to assess the frequency of similar injuries reportedly resulting from traffic crashes. The post-mortem examination revealed a left internal carotid artery dissection associated with subarachnoid hemorrhage (SAH). Based on the close temporal association, the absent prior history, and the plausibility of the injury mechanism, the injury was attributed to the braking maneuver. An analysis of NIS data demonstrated that the prevalence of subarachnoid hemorrhage is significantly higher when there is a traumatic etiology, and higher yet when the trauma is a traffic crash (odds ratio 3.3 and 4.3, respectively). The presented case, together with the hospital inpatient data analysis, indicate that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash. In a clinical or forensic setting the inference that magnitude of a trauma was low should not serve as a basis for either excluding a cervical artery dissection from a differential diagnosis, or for excluding the trauma as a cause of a diagnosed dissection. This case report illustrates a rare fatal outcome of inertial load to

    Full Text Available Purpose : Acute internal hemorrhage is an occasionally life-threatening complication in pediatric cancer patients. Many therapeutic approaches have been used to control bleeding with various degrees of success. In this study, we evaluated the efficacy of selective internal iliac artery embolization for controlling acute intractable bleeding in children with malignancies. Methods : We retrospectively evaluated the cases of 6 children with various malignancies (acute lymphoblastic leukemia, acute myelogenous leukemia, chronic myelogenous leukemia, T-cell prolymphocytic leukemia, Langerhans cell histiocytosis, and rhabdomyosarcoma, who had undergone selective arterial embolization (SAE of the internal iliac artery at the Chonnam National University Hwasun Hospital between January 2004 and December 2009. SAE was performed by an interventional radiologist using Gelfoam&#9415; and/or Tornado&#9415; coils. Results : The patients were 5 boys and 1 girl with median age of 6.9 years (range, 0.7&#8211;14.8 years at the time of SAE. SAE was performed once in 4 patients and twice in 2, and the procedure was unilateral in 2 and bilateral in 4. The causes of hemorrhage were as follows: hemorrhagic cystitis (HC in 3 patients, procedure-related internal iliac artery injuries in 2 patients, and tumor rupture in 1 patient. Initial attempt at conservative management was unsuccessful. Of the 6 patients, 5 (83.3% showed improvement after SAE without complications. Conclusion : SAE may be a safe and effective procedure for controlling acute intractable hemorrhage in pediatric malignancy patients. This procedure may obviate the need for surgery, which carries an attendant risk of morbidity and mortality in cancer patients with critical conditions.

  4. Effect of subarachnoid hemorrhage on contractile responses and noradrenaline release evoked in cat cerebral arteries by histamine

    This study analyzes the changes induced by subarachnoid hemorrhage (SAH) on the contractile responses and the noradrenaline release evoked in cat cerebral arteries by histamine. The dose-dependent vasoconstriction induced by histamine on the cerebral arteries of normal cats was significantly reduced by diphenhydramine and phentolamine. When SAH was produced 3 and 7 days before the experiment, the histamine-induced vasoconstriction also decreased. Thereafter, a tendency to normalization in the contractile vascular responses was observed such that in 15 days after the hemorrhage it was not significantly different from that found in controls animals. The decrease in the contractile responses to histamine provoked by SAH was similar to that seen after pretreatment with intracisternal injections of 6-hydroxydopamine. The amount of radioactivity released by histamine following preincubation with /sup 3/H-noradrenaline from the cerebral arteries of cats exposed to SAH 3, 7, and 15 days before the experiment was significantly reduced when compared with controls. Moreover, the basal level of tritium release and the radioactivity retained at the end of the experiment were also decreased after SAH. Results indicate histamine releases noradrenaline from cat cerebral arteries, and SAH produce a transient denervation of the perivascular adrenergic nerve endings, which explained by the impairment of the indirect adrenergic mechanism involved in the overall contractile response elicited by this amine in cerebral arteries. Histamine does not seem to play a significant role in the production of the cerebral vasospasm occurring after SAH.

    Identifying the need for interventions during hemorrhage is complicated due to physiological compensation mechanisms that can stabilize vital signs until a significant amount of blood loss. Physiological systems providing compensation during hemorrhage affect the arterial blood pressure waveform through changes in dynamics and waveform morphology. We investigated the use of Markov chain analysis of the arterial blood pressure waveform to monitor physiological systems changes during hemorrhage. Continuous arterial blood pressure recordings were made on anesthetized swine (N=7) during a 5 min baseline period and during a slow hemorrhage (10 ml/kg over 30 min). Markov chain analysis was applied to 20 sec arterial blood pressure waveform segments with a sliding window. 20 ranges of arterial blood pressure were defined as states and empirical transition probability matrices were determined for each 20 sec segment. The mixing rate (2(nd) largest eigenvalue of the transition probability matrix) was determined for all segments. A change in the mixing rate from baseline estimates was identified during hemorrhage for each animal (median time of 13 min, ~10% estimated blood volume, with minimum and maximum times of 2 and 33 min, respectively). The mixing rate was found to have an inverse correlation with shock index for all 7 animals (median correlation coefficient of -0.95 with minimum and maximum of -0.98 and -0.58, respectively). The Markov chain mixing rate of arterial blood pressure recordings is a novel potential biomarker for monitoring and understanding physiological systems during hemorrhage.

    At present there is no established therapy for treating patients with hereditary hemorrhagic telangiectasia (HHT) and symptomatic hepatic involvement. We present the results of a prospective study with 15 consecutive patients who were treated with staged hepatic artery embolization (HAE). Branches of the hepatic artery were selectively catheterized and embolized in stages using polyvinyl alcohol particles (PVA) and platinum microcoils or steel macrocoils. Prophylactic antibiotics, analgesics and anti-emetics were administered after every embolization. Clinical symptomatology and cardiac output were assessed before and after therapy as well as at the end of follow-up (median 28 months; range 10-136 months). Five patients had abdominal pain and four patients had symptoms of portal hypertension. The cardiac output was raised in all patients, with cardiac failure being present in 11 patients. After treatment, pain resolved in all five patients, and portal hypertension improved in two of the four patients. The mean cardiac output decreased significantly (P<0.001) from 12.57{+-}3.27 l/min pre-treatment to 8.36{+-}2.60 l/min at the end of follow-up. Symptoms arising from cardiac failure resolved or improved markedly in all but one patient. Cholangitis and/or cholecystitis occurred in three patients of whom two required a cholecystectomy. One patient with pre-existent hepatic cirrhosis died as a complication of the procedure. Staged HAE yields long-term relief of clinical symptoms in patients with HHT and hepatic involvement. Patients with pre-existing hepatic cirrhosis may be poor candidates for HAE. (orig.)

    Although it is widely accepted that uterine artery embolization (UAE) is an effective therapeutic strategy for postpartum hemorrhage (PPH), no consensus has been reached regarding the efficacy of UAE in patients with PPH with disseminated intravascular coagulation (DIC). This single-center retrospective cohort study included patients treated with UAE using NBCA for PPH between 2010 and 2015. The patients were divided into DIC and non-DIC groups, according to the obstetrical DIC score and the overt DIC diagnostic criteria issued by the International Society of Thrombosis and Haemostasis (ISTH), and their clinical outcomes were compared. There were 28 patients treated with UAE using NBCA. Complete hemostasis was achieved by UAE in 19 of 28 patients. In eight of nine patients with unsuccessful hemostasis, surgical hemostatic interventions were performed after UAE, and hemostasis was achieved in seven patients. UAE using NBCA showed no significant intergroup differences in complete hemostasis according to the presence or absence of DIC based on obstetrical DIC score (70% versus 62.5%, P = 1.000) or ISTH DIC score (54.5% versus 76.5%, P = 0.409). UAE using NBCA may be a useful first-choice treatment for PPH with DIC.

    Full Text Available Role of atherosclerosis in the pathogenesis of ischemic and hemorrhagic infarctions is still matter of debate. Intima-media thickness (IMT of the common carotid artery (CCA and internal carotid artery (ICA are markers of atherosclerosis. The aim of this study was to compare CCA IMT and ICA IMT of patients with ischemic and hemorrhagic infarction.Two equal groups of 80 patients with small and large vessel ischemic stroke and 80 patients with non-traumatic intracerebral hemorrhage (ICH who referred to our central teaching hospital of Zahedan were assessed in this descriptive study. IMT of four arteries (right and left CCA and ICA were measured, and collected data were analysis using Student's t-test.There were 137 males (57.1% and 103 (42.9% female with mean age of 62.7 ± 11.7. Mean right CCA IMT of patients with small vessel diseases (SVD, large vessel diseases (LVD, and ICH were 0.564 ± 0.130, 0.623 ± 0.150, and 0.580 ± 0.140 mm, respectively (P = 0.032. Mean left CCA IMT of patients with SVD, LVD, and ICH were 0.569 ± 0.120, 0.618 ± 0.120, and 0.573 ± 0.130 mm, respectively (P = 0.039. The above findings for right ICA were 0.572 ± 0.120, 0.569 ± 0.140, and 0.522 ± 0.130 mm, respectively (P = 0.145. Those findings for left ICA IMT were 0.525 ± 0.110, 0.554 ± 0.120, and 0.527 ± 0.120 mm, respectively (P = 0.257.Our findings showed that by using CCA IMT, differentiation between small and large vessel infarctions and hemorrhagic infarctions can be made.

    Purpose: Major arterial hemorrhage is an uncommon but serious complication of pancreatitis with high morbidity and mortality. Digital subtraction angiography (DSA) has long been the gold standard for the detection of a visceral artery pseudoaneurysm or for the site of active bleeding in patients with pancreatitis. Multi-section CT angiography is a minimally invasive technique which can provide high-resolution and high-contrast images of the arterial lumen and wall, with a much lower risk of complication and morbidity compared to DSA. The aim of this study was to determine the accuracy of multi-section CT angiography for the diagnosis of arterial complications of inflammatory pancreatitic disease. Materials and methods: A retrospective analysis of all patients undergoing visceral angiography for major bleeding as a complication of pancreatitis between 1998 and 2004 was performed. Twenty-nine studies in 25 patients (20 males, 5 females) with a mean age of 50.9 years (range 11-67 years) were identified where multi-section CT angiography was performed in the 24 h preceding the digital subtraction angiogram. Results: Digital subtraction angiography detected a pseudoaneurysm or contrast extravasation in 19 studies and no bleeding was demonstrated in 9 studies. CT angiography correctly identified the site and type of bleeding in 18 of the 19 positive studies. CT angiography detected extravasation of contrast in one study that was not demonstrated on digital subtraction angiography. The sensitivity and specificity for multi-section CT angiography for the detection of major arterial bleeding on a background of pancreatitis were 0.947 and 0.900, respectively. Conclusion: Multi-section CT angiography is a sensitive and accurate technique for the detection of major arterial hemorrhage in inflammatory pancreatic disease and should be considered as the first investigation in the management of these patients.

    Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

  11. Continuous Selective Intra-Arterial Application of Nimodipine in Refractory Cerebral Vasospasm due to Aneurysmal Subarachnoid Hemorrhage

    Full Text Available Background. Cerebral vasospasm is one of the leading courses for disability in aneurysmal subarachnoid hemorrhage. Effective treatment of vasospasm is therefore one of the main priorities for these patients. We report about a case series of continuous intra-arterial infusion of the calcium channel antagonist nimodipine for 1–5 days on the intensive care unit. Methods. In thirty patients with aneurysmal subarachnoid hemorrhage and refractory vasospasm continuous infusion of nimodipine was started on the neurosurgical intensive care unit. The effect of nimodipine on brain perfusion, cerebral blood flow, brain tissue oxygenation, and blood flow velocity in cerebral arteries was monitored. Results. Based on Hunt & Hess grades on admission, 83% survived in a good clinical condition and 23% recovered without an apparent neurological deficit. Persistent ischemic areas were seen in 100% of patients with GOS 1–3 and in 69% of GOS 4-5 patients. Regional cerebral blood flow and computed tomography perfusion scanning showed adequate correlation with nimodipine application and angiographic vasospasm. Transcranial Doppler turned out to be unreliable with interexaminer variance and failure of detecting vasospasm or missing the improvement. Conclusion. Local continuous intra-arterial nimodipine treatment for refractory cerebral vasospasm after aSAH can be recommended as a low-risk treatment in addition to established endovascular therapies.

  12. Treatment of Esophageal Variceal Hemorrhage with Self-Expanding Metal Stents as a Rescue Maneuver in a Swiss Multicentric Cohort

    Directory of Open Access Journals (Sweden)

    Fabienne C. Fierz

    2013-03-01

    Full Text Available Acute esophageal variceal bleeding in patients with portal hypertension remains a complication with a high mortality today. In cases refractory to standard therapy including endoscopic band ligation and pharmacological therapy, traditionally balloon tamponade has been used as salvage therapy. However, these techniques show several important limitations. Self-expanding metal stents (SEMS have been proposed as an alternative rescue treatment. The use of variceal stenting in 7 patients with a total of 9 bleeding episodes in three different Swiss hospitals is demonstrated. While immediate bleeding control is achieved in a high percentage of cases, the 5-day and 6-week mortality rate remain high. Mortality is strongly influenced by the severity of the underlying liver disease. Accordingly, our data represent a high-risk patient collective. Thanks to their safety and easy handling, SEMS are an interesting alternative to balloon tamponade as a bridging intervention to definitive therapy including the pre-hospital setting.

    The purpose of this study was to report our experience in the management of severe primary postpartum hemorrhage due to genital tract laceration following operative vaginal delivery with forceps using pelvic transcatheter arterial embolization (TAE). Ten women (mean age, 31.9 years) with severe primary postpartum hemorrhage due to genital tract laceration after operative delivery with forceps were treated with TAE. TAE was indicated because of intractable bleeding that could not be controlled with uterotonic drugs, blood transfusion, attempted suturing and packing in all patients. Postdelivery perineal examination showed cervical or vaginal tears in all women and associated paravaginal hematoma in four. Angiography revealed extravasation of contrast material in six patients. TAE performed with gelatin sponge allowed to control the bleeding in all patients. Cervical and vaginal suturing was made possible and successfully achieved in the six women who had failed suturing attempts before TAE. Paravaginal hematoma was successfully evacuated in four patients in whom it was present after TAE. No complications related to TAE were noted. We conclude that in women with severe primary postpartum hemorrhage due to genital tract laceration after operative delivery with forceps, TAE is effective and safe for stopping the bleeding and helps genital tract suturing and evacuation of hematoma.

    Purpose: To compare heart and coronary artery radiation exposure using intensity-modulated radiotherapy (IMRT) vs. four-field three-dimensional conformal radiotherapy (3D-CRT) treatment plans for patients with distal esophageal cancer undergoing chemoradiation. Methods and Materials: Nineteen patients with distal esophageal cancers treated with IMRT from March 2007 to May 2008 were identified. All patients were treated to 50.4 Gy with five-field IMRT plans. Theoretical 3D-CRT plans with four-field beam arrangements were generated. Dose-volume histograms of the planning target volume, heart, right coronary artery, left coronary artery, and other critical normal tissues were compared between the IMRT and 3D-CRT plans, and selected parameters were statistically evaluated using the Wilcoxon rank-sum test. Results: Intensity-modulated radiotherapy treatment planning showed significant reduction (p < 0.05) in heart dose over 3D-CRT as assessed by average mean dose (22.9 vs. 28.2 Gy) and V30 (24.8% vs. 61.0%). There was also significant sparing of the right coronary artery (average mean dose, 23.8 Gy vs. 35.5 Gy), whereas the left coronary artery showed no significant improvement (mean dose, 11.2 Gy vs. 9.2 Gy), p = 0.11. There was no significant difference in percentage of total lung volume receiving at least 10, 15, or 20 Gy or in the mean lung dose between the planning methods. There were also no significant differences observed for the kidneys, liver, stomach, or spinal cord. Intensity-modulated radiotherapy achieved a significant improvement in target conformity as measured by the conformality index (ratio of total volume receiving 95% of prescription dose to planning target volume receiving 95% of prescription dose), with the mean conformality index reduced from 1.56 to 1.30 using IMRT. Conclusions: Treatment of patients with distal esophageal cancer using IMRT significantly decreases the exposure of the heart and right coronary artery when compared with 3D

    2008-07-11

    Pseudoaneurysms of the hepatic artery are a rare complication in patients with primary or secondary liver tumors treated with intra-arterial chemotherapy. We present two patients who developed this complication after placement of a catheter system into the gastroduodenal artery and initiation of regional chemotherapy with floxuridine. Diagnosis was made after symptomatic bleeding occurred, necessitating emergency angiography with coil embolization. Pseudoaneurysms usually occur after mechanical damage of the vessel wall, but the chemical toxicity of floxuridine may add to the development of vascular impairment.

    2015-02-01

    Abnormal uterine bleeding and other gynecologic complications associated with a previous cesarean section scar are only recently being identified and described. Herein we report a rare case of a woman with recurring massive uterine bleeding after 2 cesarean sections. Curettage and hormone therapy were unsuccessfully used in an attempt to control the bleeding. After she was transferred to our hospital, she had another episode of vaginal bleeding that was successfully managed with oxytocin and hemostatic. Diagnostic hysteroscopy performed under anesthesia revealed an abnormal transected artery in the cesarean section scar with a thrombus visible. In the treatment at the beginning of laparoscopic management, we adopted temporary bilateral uterine artery occlusion with titanium clips to prevent massive hemorrhage. Secondly, with the aid of hysteroscopy, the bleeding site was opened, and then the cesarean scar was wedge resected and stitched interruptedly with 1-0 absorbable sutures. The postoperative recovery was uneventful. It would seem that the worldwide use of cesarean section delivery may contribute to the risk of gynecologic disturbances including some unrecognized and complex conditions as seen in this case.

    The incidence of convulsion and associated factors were retrospectively analyzed in 23 patients with symptomatic cerebral vasospasm following subarachnoid hemorrhage (SAH) who underwent a total of 31 intra-arterial infusion of fasudil hydrochloride (IAFH) procedures in 49 vessels. Fasudil hydrochloride was administered by superselective infusion via a microcatheter positioned at the proximal portion of the affected artery. Thirteen procedures were performed by manually controlled infusion of 30-75 mg fasudil hydrochloride (1.2-3.75 mg/ml) for approximately 10 minutes. Eighteen procedures were performed by continuous infusion of 60 mg fasudil hydrochloride (1.2 mg/ml) by infusion pump at a constant rate of 3 mg/min. Neurological improvement was observed after 18 of 22 procedures in patients with neurological deterioration due to vasospasm. Convulsion during IAFH developed in 4 patients, all treated by manual infusion (p convulsion during IAFH. IAFH was effective for treating cerebral vasospasm following aneurysmal SAH. IAFH at a constant rate of 3 mg/min delivered by infusion pump improved the symptoms of cerebral vasospasm and prevented convulsions during IAFH.

    A 87-year-old man received radical nephroureterectomy for right renal pelvic cancer in 2009 and left cutaneous ureterostomy after radical cystectomy for bladder cancer in 2013. He visited the hospital for exchanging a 7 or 8 Fr single-J catheter every 2 to 4 weeks. Eleven months after the 2nd operation, massive bleeding from the stoma occurred when ureteral catheter was exchanged. Contrast-enhanced computed tomography showed that left inferior epigastric artery was located close to left ureter. Angiography of the left inferior epigastric artery didn't show an obvious fistula, but revealed the stoma was surrounded by ramified new blood vessels from left inferior epigastric artery. We suspected a rupture of the vessels and performed embolization for the branch of inferior epigastric artery to left ureter. This embolization made it possible for the bleeding to be controlled. Massive bleeding from the branch of inferior epigastric artery is very rare, and we report the case and review the literature.

    Nontraumatic (or spontaneous) intracranial hemorrhage most commonly involves the brain parenchyma and subarachnoid space. This entity accounts for at least 10% of strokes and is a leading cause of death and disability in adults. Important causes of spontaneous intracranial hemorrhage include hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformations, and hemorrhagic infarcts (both venous and arterial). Imaging findings in common and less common causes of spontaneous intracranial hemorrhage are reviewed.

    Full Text Available Background: The data on incidence of hypopituitarism after SAH are conflicting. Furthermore, it is still not known whether there is any difference in hormonal deficiencies between SAH due to anterior communicating artery (A-com and middle cerebral artery (MCA aneurysms. Materials and Methods: This study includes both retrospective and prospective arms. The data collected included baseline demographic profile, clinical severity on admission to the hospital by the Hunt and Hess grading system and World Federation of Neurological Surgeons (WFNS grading, radiological severity of bleed by the Fisher′s classification, and treatment details. All the patients underwent detailed hormonal evaluation at baseline and 6 months in prospective group while at the end of 1 year in the retrospective group. Hormonal deficiencies between patients with A-com and MCA aneurysmal SAH were compared using appropriate statistical tests. Results: Of 60 patients studied, 47 patients (A-com: 28 and MCA: 19 were in the retrospective group, while 13 patients (A-com-9, MCA-4 were in the prospective group. The baseline data were comparable between the two groups. At or after 6 months follow-up, 19 (31.6% patients, 10 patients with A-com and 9 patients with MCA aneurysmal SAH, had some form of hormone deficiency. Furthermore, there was no difference in endocrine dysfunctions between the two groups. There was no correlation between the severity of hormonal deficiency and the clinical severity of SAH grade by Hunt and Hess and radiological grade of SAH by Fisher′s grade. Conclusion: Hormonal deficiencies are not uncommon in patients with SAH. There is no difference in hormonal deficiencies and severity of hypopituitarism in patients with SAH due to A-com and MCA bleed.

    Aplastic or twig-like middle cerebral artery (Ap/T-MCA) is a rare anatomical anomaly, which can be associated with intracranial hemorrhage and cerebral ischemia. A 52-year-old woman who presented with sudden headache was admitted to our hospital. Computed tomography (CT) and magnetic resonance imaging showed no abnormality; however, magnetic resonance angiogram revealed an occlusion or severe stenosis in the left middle cerebral artery. Three-dimensional CT angiography demonstrated severe stenosis in the left middle cerebral artery. The patient was discharged without any neurological deficit; however, she subsequently complained of temporary weakness in the right hand. It was possibly due to a transient ischemic attack; therefore, cilostazol 200 mg/day was administered for prevention of cerebral ischemia. Single photon emission computed tomography(with or without administration of acetazolamide)showed neither significant decrease in the cerebral blood flow nor cerebrovascular reactivity; hence, surgical revascularization was not performed. However, two years after the initial admission, she was urgently admitted to our hospital with sudden headache and nausea followed by aphasia and weakness of the right extremities. CT images showed diffuse subarachnoid hemorrhage and intracerebral hemorrhage in the left temporo-parietal lobe. Cerebral angiography revealed that the left middle cerebral artery was Ap/T-MCA without cerebral aneurysms. The patient was treated conservatively, and she eventually recovered without any neurological deficit except mild aphasia. Since Ap/T-MCA is associated with both hemorrhagic and ischemic stroke, antiplatelet therapy should be administered carefully. Moreover, it is necessary to consider extracranial-intracranial bypass to reduce hemodynamic stress on the abnormal vessels.

    Full Text Available OBJECTIVE: To investigate the changes in the currents of voltage-dependent calcium channels (VDCCs in smooth muscle cells of basilar artery in a rabbit model of subarachnoid hemorrhage (SAH. METHODS: New Zealand white rabbits were randomly divided into five groups: sham (C, normal (N, 24 hours (S1, 48 hours (S2 and 72 hours (S3 after SAH. Non-heparinized autologous arterial blood (1 ml/kg was injected into the cisterna magna to create SAH after intravenous anesthesia, and 1 ml/kg of saline was injected into cisterna magna in the sham group. Rabbits in group N received no injections. Basilar artery in S1, S2, S3 group were isolated at 24, 48, 72 hours after SAH. Basilar artery in group C was isolated at 72 hours after physiological saline injection. Basilar artery smooth muscle cells were isolated for all groups. Whole-cell patch-clamp technique was utilized to record cell membrane capacitance and VDCCs currents. The VDCCs antagonist nifedipine was added to the bath solution to block the Ca(++ channels currents. RESULTS: There were no significant differences in the number of cells isolated, the cell size and membrane capacitance among all the five groups. VDCC currents in the S1-S3 groups had higher amplitudes than those in control and sham groups. The significant change of current amplitude was observed at 72 hours after SAH, which was higher than those of 24 and 48 hours. The VDCCs were shown to expression in human artery smooth muscle cells. CONCLUSIONS: The changes of activation characteristics and voltage-current relationship at 72 hours after SAH might be an important event which leads to a series of molecular events in the microenvironment of the basilar artery smooth muscle cells. This may be the key time point for potential therapeutic intervention against subarachnoid hemorrhage.

    Aneurysms of the cavernous segment of the internal carotid artery (ICA) are believed to have a low risk of subarachnoid haemorrhage (SAH), given the confines of the dural rings and the anterior clinoid process. The risk may be greater when the bony and dural protection has been eroded. We report a case of spontaneous SAH from rupture of a cavernous ICA aneurysm in a patient whose large prolactinoma had markedly decreased in size as the result of cabergoline treatment. After passing a balloon test occlusion, the patient underwent successful endovascular vessel deconstruction. This case suggests that an eroding skull base lesion may distort normal anterior cranial base anatomy and allow communication between the cavernous ICA and subarachnoid space. The potential for SAH due to cavernous ICA aneurysm rupture should be recognised in patients with previous pituitary or other skull base lesions adjacent to the cavernous sinus.

    When surgery is indicated for bleeding duodenal ulcer, the traditional standard of care has been "radical surgical treatment is preferable to conservative therapy since the risk of rebleeding is reduced without an augmentation in morbidity and mortality". This principle is based on two prospective studies published before 1995. Radical surgery at that time consisted of antrectomy, while conservative therapy included oversewing of the bleeding vessel in the ulcer bed and ligation of the gastroduodenal artery (Weinberg procedure). This strategy must be re-evaluated in 2008 in view of our better understanding of the role of Helicopacter pylori in the causation of duodenal ulceration and the decreased risk of post-operative re-bleeding with the use of proton pump inhibitors. The role of surgery has changed. Its aim is no longer to cure the ulcer diathesis but rather to urgently control bleeding in anticipation of ulcer cure with medical therapy.

    To investigate risk factors related to severe bleeding necessitating renal artery embolization (RAE) after percutaneous nephrostomy (PCN). 36 patients who underwent RAE from January 2005 to June 2014 were retrospectively reviewed. Among them, 10 patients underwent embolization because of severe bleeding after PCN (bleeding group). From 1762 patients who underwent PCN in the same period, we selected 21 patients who underwent PCN without bleeding after the procedure (non-bleeding group). We investigated possible related risk factors, such as the presence of underlying diseases, activated partial thromboplastin time (aPTT), prothrombin time (PT), platelet count, puncture site, procedure time, size of the kidney, distance from skin to renal cortex, maximum caliber of the indwelling catheter, parenchymal thickness, and grade of hydronephrosis. We used Fisher's exact test and independent t test for data analyses. We classified hydronephrosis as either 'mild hydronephrosis,' or 'moderate or severe hydronephrosis.' The frequency of mild hydronephrosis was 80.0% (8/10) in the bleeding group and 33.3% (7/21) in the non-bleeding group (p = 0.023). There were no significant differences between the two groups in the incidence of underlying diseases. Similarly, other risk factors (PT, aPTT, platelet count, procedure time, distance from skin to renal cortex, maximum caliber of the indwelling catheter, kidney size, and parenhcymal thickness) also did not differ significantly between the two groups. Mild hydronephrosis is a risk factor for severe bleeding necessitating RAE after PCN. Therefore, when performing PCN, careful attention should be paid to patients with mild hydronephrosis.

    Segmental arterial mediolysis (SAM) is a rare, non-inflammatory, non-atherosclerotic vasculopathy typically affecting the abdominal arteries although it may also affect the great vessels and cerebral vasculature. Diseased vessels manifest with aneurysms and/or dissections, often presenting clinically with catastrophic thromboembolic injury and less frequently with subarachnoid hemorrhage (SAH). The etiology of SAM remains indeterminate although there is evidence it may be an endogenous pathological response to vasospasm. The SAM literature is reviewed and a case of SAH related to a ruptured dissecting-type vertebral artery aneurysm is described. In addition to furthering awareness of SAM, this unique case offers insight into the acute phase of the disease and the potential role of vasospastic induction.

    Purpose: Presentation of temporary balloon occlusion as an interventional radiological method for managing hemorrhage in multiply injured patients with uncontrollable loss of blood. Method: Temporary, non-selective arterial occlusion by introduction of a balloon catheter contralaterally to the source of bleeding has been performed since 1992 on 7 patients with multiple injuries, hemorrhagic shock requiring reanimation, and angiographic demonstration of an arterial hemorrhage in the supply region of the internal iliac artery with complex pelvic fracture. In each case a PTA balloon catheter was introduced transfemorally, non-selectively positioned proximal to the bleeding source, and left in place for 24-48 h under manometric control. Control angiographies were performed prior to catheter removal. Results: The bleeding was stopped immediately in all 7 patients. The hemodynamic stability made transport and thus further surgical management and/or a short-term treatment in the intensive-care station possible. Control angiographies confirmed that the bleeding had stopped in all patients. Conclusions: We recommend temporary balloon occlusion as a rapid and effective method for the management of bleeding in otherwise uncontrollable traumatic hemorrhages in the supply region of the internal iliac artery.

    BACKGROUND AND PURPOSE: The pathogenesis of cerebral ischemia associated with subarachnoid hemorrhage (SAH) still remains elusive. The aim of this study was to examine the involvement of mitogen-activated protein kinase (MAPK) and protein kinase C (PKC) subtypes in the pathophysiology of cerebral...... enhanced phosphorylation only at 48 hours after SAH. The pattern was identical in large cerebral arteries and in intracerebral microvessels. Treatment with either the PKC (RO-31-7549) or the raf (SB386023-b) inhibitor prevented the kinase activation. CONCLUSIONS: The results show that specific subtypes...... ischemia after SAH in cerebral arteries and microvessels and to examine temporal activation of the kinases. We hypothesize that treatment with a MAPK or PKC inhibitor will prevent the SAH-induced kinase activation in brain vessels. METHODS: SAH was induced by injecting 250 microL blood...

    Despite advances in our knowledge of esophageal cancer, 50% of patients present with incurable disease, and the overall survival after diagnosis is poor. The incidence of esophageal adenocarcinoma of the distal esophagus is rising at a rapid rate in developed countries. Recent advances in the epidemiology of esophageal cancer offer insights into preventive strategies in patients who are at risk. New developments in diagnosis may help detect the disease at an early stage. New diagnostic modalities permit more accurate staging procedures and allow appropriate selection of therapy. New studies provide more information on multimodality therapy for esophageal cancer, and new endoscopic techniques allow resection of small lesions without surgery. New stent designs provide better palliation by providing tumor ingrowth. These developments in the treatment of esophageal cancer are the focus of this review.

    Context: Concurrent arterial aneurysms (AAs) occurring in 2.7-16.7% patients harboring an arteriovenous malformation (AVM) aggravate the risk of intracranial hemorrhage. Aim: We evaluate the variations of aneurysms simultaneously coexisting with AVMs. A classification-based management strategy and an abbreviated nomenclature that describes their radiological features is also proposed. Setting: Tertiary care academic institute. Statistics: Test of significance applied to determine the factors causing rebleeding in the groups of patients with concurrent AVM and aneurysm and those with only AVMs. Subjects and Methods: Sixteen patients (5 with subarachnoid hemorrhage and 11 with intracerebral/intraventricular hemorrhage; 10 with low flow [LF] and 6 with high flow [HF] AVMs) underwent radiological assessment of Spetzler Martin (SM) grading and flow status of AA + AVM. Their modified Rankin's score (mRS) at admission was compared with their follow-up (F/U) score. Results: Pre-operative mRS was 0 in 5, 2 in 6, 3 in 1, 4 in 3 and 5 in 1; and, SM grade I in 5, II in 3, III in 3, IV in 4 and V in 1 patients, respectively. AA associated AVMs were classified as: (I) Flow-related proximal (n = 2); (II) flow-related distal (n = 3); (III) intranidal (n = 5); (IV) extra-intranidal (n = 2); (V) remote major ipsilateral (n = 1); (VI) remote major contralateral (n = 1); (VII) deep perforator related (n = 1); (VIII) superficial (n = 1); and (IX) distal (n = 0). Their treatment strategy included: Flow related AA, SM I-III LF AVM: aneurysm clipping with AVM excision; nidal-extranidal AA, SM I-III LF AVM: Excision or embolization of both AA + AVM; nidal-extranidal and perforator-related AA, SM IV-V HF AVM: Only endovascular embolization or radiosurgery. Surgical decision-making for remote AA took into account their ipsilateral/contralateral filling status and vessel dominance; and, for AA associated with SM III HF AVM, it varied in each patient based on diffuseness of AVM nidus, flow

  5. Alteration of Basilar Artery Rho-Kinase and Soluble Guanylyl Cyclase Protein Expression in a Rat Model of Cerebral Vasospasm following Subarachnoid Hemorrhage

    Chih-Jen Wang

    2014-01-01

    Full Text Available Background and Purpose. The vasoconstrictor endothelin-1 (ET-1 has been implicated in the pathogenesis of cerebral vasospasm following subarachnoid hemorrhage (SAH. Previous results showed that CGS 26303, an endothelin converting enzyme (ECE inhibitor, effectively prevented and reversed arterial narrowing in animal models of SAH. In the present study, we assessed the effect of CGS 26303 on neurological deficits in SAH rats. The involvement of vasoactive pathways downstream of ET-1 signaling in SAH was also investigated. Methods. Sprague-Dawley rats were divided into five groups (n=6/group: (1 normal control, (2 SAH, (3 SAH+vehicle, (4 SAH+CGS 26303 (prevention, and (5 SAH+CGS 26303 (reversal. SAH was induced by injecting autologous blood into cisterna magna. CGS 26303 (10 mg/kg was injected intravenously at 1 and 24 hr after the initiation of SAH in the prevention and reversal protocols, respectively. Behavioral changes were assessed at 48 hr after SAH. Protein expression was analyzed by Western blots. Results. Deficits in motor function were obvious in the SAH rats, and CGS 26303 significantly improved the rate of paraplegia. Expressions of rho-kinase-II and membrane-bound protein kinase C-δ and rhoA were significantly increased, while those of soluble guanylyl cyclase α1 and β1 as well as protein kinase G were significantly decreased in the basilar artery of SAH rats. Treatment with CGS 26303 nearly normalized these effects. Conclusions. These results demonstrate that the rhoA/rho-kinase and sGC/cGMP/PKG pathways play pivotal roles in cerebral vasospasm after SAH. It also shows that ECE inhibition is an effective strategy for the treatment of this disease.

    2015-01-01

    This review gives an overview of the esophageal anastomosis. The history, various techniques and substitution organs, their advantages and disadvantages, healing mechanism, complications, and actual trend of this essential part of esophageal surgery are described. The history of the esophageal anastomosis extending from the first anastomosis in 1901 to today has undergone more than one century. In the early days, the success rate of the anastomosis was extremely low. As the technology progressed, the anastomosis got significant achievement. Various anastomotic techniques are currently being used. However, controversies exist on the choice of anastomotic method concerning the success rate, postoperative complication and quality of life. How to choose the method, no one can give the best answer. We searched the manuscripts about the esophageal anastomoses in recent years and studied the controversy questions about the anastomosis. Performing an esophageal anastomosis is a technical matter, and suture healing is independent of the patient's biologic situation. Every anastomosis technique has its own merit, but the outcomes were different if it was performed by different surgeons, and we also found that the complication rate of the anastomosis was mainly associated with the surgeons. So the surgeons should learn from their previous experience and others to avoid technical errors.

    2009-01-01

    Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. In addition,it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modi f icat ions, topical cor t icosteroids and endoscopic dilation can be used alone or in combination.

    Full Text Available Mucormycosis is a rare invasive fungal infection with high mortality. It usually affects patients with poorly controlled diabetes, immunosuppression, or hematological malignancies. Gastroenterologists need to be aware of this rare infection because endoscopy can facilitate early diagnosis and prompt appropriate therapy. Here we describe a case of invasive esophageal mucormycosis that developed in a 63-year-old man with diabetes, acute promyelocytic leukemia, and prolonged leukopenia after chemotherapy. Upper endoscopy showed distal circumferential esophageal wall thickening with devitalization. The mucosa did not bleed after endoscopic biopsy. Histopathology confirmed mucormycosis. He was treated with various antifungal agents including echinocandins, fluconazole, and liposomal amphotericin B. Despite aggressive antifungal therapy and supportive care, the patient died 24 days later.

    1985-05-01

    Computerized tomography, carotid angiograms, and arteriography were used to diagnose several cases of cerebral hemorrhage following the use of phenylpropanolamine. The angiographic picture in one of the three cases was similar to that previously described in association with amphetamine abuse and pseudoephedrine overdose, both substances being chemically and pharmacologically similar to phenylpropanolamine. The study suggests that the arterial change responsible for symptoms may be due to spasm rather than arteriopathy. 14 references, 5 figures.

Nonoperative management of kidney hemorrhage after MPCNL following complete radiographic assessment has become an accepted if not preferred therapeutic option. In this article, we will study the methods and treatment effects of selective renal arterial embolization on kidney hemorrhage after MPCNL. Methods From April 2008 to October 2009, 15 cases with nephrorrhagia after MPCNL underwent interventional therapy of selective renal arterial embolization. Results Overall, 14 of 15 patients had prompt hemostasis documented either on the post-embolization angiogram or by clinical assessment. In 1 patient, bleeding was recurred and another transcatheter embolization was required. The technical successful rate with single session was 93. 3% (14/15). There was no complication occurred after the selective renal arterial embolization. Conclusion The angiography with transcatheter embolization techniques provides a safe and effective means of managing renal artery branch injuries secondary to MPCNL.

    Objective To evaluate the value of superselective renal arterial embolization for renal hemorrhage. Methods 15 cases with traumatic or iatrogenic renal hemorrhage were examined by selective renal arterial angiography from 2006 March to 2011 Janu ary. Postoperative condition was observed 3d followed by superselective arterial embolization through guidance of steel coil. And re sidual renal function was evaluated by ultrasound and CT at 1,3,6,and 12 Months after the treatment. Results 11 cases were con firmed with renal arterial pseudoaneurysms and 4 cases with arteriovenous fistula by DSA in 15 cases. The successful rate of the tar get artery superselective catheterization was 100% (15/15). The rates of stopping bleeding at 24— 48 h and 72 h after operation were 80% (12/15) and 20% (3/15) respectively. The successful rate of disposable embolization was 100% (15/15). The residual renal function of all cases kept good at 1 year after operation. Conclusion Arterial angiography can rapidly and accurately diagnose the pathogeny of renal hemorrhage and the bleeding artery. The hemostatic curative effect of superselective catheterization was sure, and it should be used as the preferred method of diagnosis and treatment on renal hemorrhage.%目的 评价超选择性肾动脉插管栓塞对肾大出血的价值.方法 对该院2006年3月至2011年1月15例外伤性或医源性肾大出血进行选择性肾动脉造影检查,对出血动脉超选择性插管后以弹簧钢圈实施栓塞,术后3 d内观察止血情况,1、3、6、12个月行超声、CT等检查评价残肾功能.结果 15例经肾动脉血管造影(DSA)检查证实为假性动脉瘤11例、同时伴动-静脉瘘4例,靶动脉超选择性插管栓塞成功率100%(15/15),术后24~48 h及72 h停止出血分别为80%(12/15)、20%(3/15),一次性栓塞止血成功率100%(15/15).术后1年残肾功能良好100%(15/15).结论 动脉造影可迅速、准确诊断肾大出血原因及出血动脉,靶动脉超选

    Moyamoya disease (MMD) is a chronic progressive cerebrovascular disease, which can be divided into three types: ischemic, hemorrhagic, and asymptomatic. Hemorrhagic MMD has attracted considerable attention due to its distinctive imaging features and the controversy over the treatment. This report presents a comprehensive review of the literature on hemorrhagic MMD, focusing on the epidemiological characteristics, etiology and pathogenesis, imaging features, predictors of hemorrhage, and treatment options and their efficacy of hemorrhagic MMD. Hemorrhagic MMD mainly occurs in adult patients in Asian countries, and many factors may contribute to the etiology and development of this disease. Hemorrhagic MMD has two major imaging features: the dilatation and abnormal branching of anterior choroidal artery or posterior communicating artery, and multiple microbleeds, which may predict subsequent hemorrhage. The treatment for hemorrhagic MMD is not standardized, and large sample prospective randomized clinical trials may help to determine which method is better. In hemorrhagic MMD patients, more attention should be paid to cognitive function and quality of life, and these assessments should be included in the evaluation of effectiveness of treatment modalities.

    Cerebral hemorrhagic infarction visualized on CT, secondary to embolic stroke in an anticoagulated individual, is usually associated with clinically stable or improving neurologic signs; fear of transforming the hemorrhagic infarction into a hematoma, however, usually prompts cessation of anticoagulation until the blood has cleared on CT, despite the recognized risk of recurrent embolism during this non-anticoagulated period. We now report our experience with 12 patients with hemorrhagic infarction who remained anticoagulated. Eleven men and one woman, ages 33 to 77, developed hemorrhagic infarction while on heparin, warfarin, or both, for prevention of recurrent embolism. Patients were either continued on uninterrupted anticoagulation from stroke onset (n = 6), or anticoagulation was withheld for several days and then resumed (n = 4), or it was withheld for 5 and 14 days (n = 2) after stroke onset and then continued uninterrupted despite the CT appearance of hemorrhagic infarction. Eleven patients had a definite cardioembolic source for stroke (atrial fibrillation, seven; ventricular thrombus, two; and ventricular dyskinesia, two). One patient had carotid occlusion with local intra-arterial embolism. Hemorrhagic infarcts varied in size and were located in the middle cerebral artery territory in 11 patients and posterior cerebral artery territory in one. All patients remained clinically stable or improved on anticoagulation. Serial CTs showed fading hemorrhagic areas. When the risk of recurrent embolism is high, anticoagulation may be safely used in some patients with hemorrhagic infarction.

    2015-04-01

    Alveolar hemorrhage occurs relatively rarely and is a therapeutic emergency because it can quickly lead to acute respiratory failure, which can be fatal. Hemoptysis associated with anemia and pulmonary infiltrates suggest the diagnosis of alveolar hemorrhage, but may be absent in one third of cases including patients in respiratory distress. The diagnosis of alveolar hemorrhage is based on the findings of a bronchoalveolar lavage. The causes are numerous. It is important to identify alveolar hemorrhage due to sepsis, then separate an autoimmune cause (vasculitis associated with antineutrophil cytoplasmic antibody, connective tissue disease and Goodpasture's syndrome) with the search for autoantibodies and biopsies from readily accessible organs, from a non-immune cause, performing echocardiography. Lung biopsy should be necessary only in exceptional cases. If the hemorrhage has an immune cause, treatment with steroids and cyclophosphamide may be started. The indications for treatment with rituximab are beginning to be established (forms that are not severe and refractory forms). The benefit of plasma exchange is unquestionable in Goodpasture's syndrome. In patients with an immune disease that can lead to an alveolar hemorrhage, removing any source of infection is the first priority.

    Hemorrhagic events associated with cerebral paragonimiasis are not rare, especially in children and adolescents; however, angiographic evidence of cerebrovascular involvement has not been reported. The authors describe angiographic abnormalities of the cerebral arteries seen in 2 children in whom cerebral paragonimiasis was associated with hemorrhagic stroke. The patients presented with acute intracerebral and subarachnoid hemorrhage. Angiography revealed a beaded appearance and long segmental narrowing of arteries, consistent with arteritis. In both patients, involved vessels were seen in the area of the hemorrhage. The vascular changes and the hemorrhage, together with new lesions that developed close to the hemorrhage and improved after praziquantel treatment, were attributed to paragonimiasis. Further study of the frequency and mechanism of hemorrhagic cerebrovascular complications associated with cerebral paragonimiasis is needed.

    2003-01-01

    Full Text Available Foreign bodies in the esophagus are uncommon causes of esophageal perforation. Many nonperforating cases are successfully managed by flexible gastroscopy. However, complicated foreign bodies such as those that result in esophageal perforation and vascular injury are best managed surgically. Gastroscopy remains the primary method of diagnosis. A case of a 59-year-old woman who developed retrosternal and intrascapular pain, odynophagia and hematemesis after eating fish is reported. Flexible gastroscopy showed arterial bleeding from the midthoracic esophagus. Computed tomography scan localized a 3 cm fish bone perforating the esophagus with surrounding hematoma. An aortogram did not reveal an actively bleeding aortoesophageal fistula. The fish bone was surgically removed and the patient recovered with no postoperative complications. This case illustrates the importance of early consideration for surgical intervention when confronted with a brisk arterial bleed from the esophagus with suggestive history of foreign body ingestion.

    2005-01-01

    The author presents three cases of esophageal rupture during the treatment of massive esophageal variceal bleeding with Sengstaken-Blakemore (SB) tube. In each case, simple auscultation was used to guide SB tube insertion, with chest radiograph obtained only after complete inflation of the gastric balloon. Two patients died of hemorrhagic shock and one died of mediastinitis.The author suggests that confirmation of SB tube placement by auscultation alone may not be adequate.Routine chest radiographs should be obtained before and after full inflation of the gastric balloon to confirm tube position and to detect tube dislocation.

    A non cirrhotic patient with esophageal varices and portal vein thrombosis had recurrent variceal bleeding unsuccessfully controlled by endoscopy and esophageal transection. Emergency transhepatic portography confirmed the thrombosed right branch of the portal vein, while the left branch appeared angulated, shifted and stenotic. A stent was successfully implanted into the left branch and the collateral vessels along the epatoduodenal ligament disappeared. In patients with esophageal variceal hemorrhage and portal thrombosis if endoscopy fails, emergency esophageal transection or nonselective portocaval shunting are indicated. The rare patients with only partial portal thrombosis can be treated directly with stenting through an angioradiologic approach. PMID:18644135

    Genetic abnormalities of proto-oncogenes and tumor suppressor genes have been demonstrated to be changes that are frequently involved in esophageal cancer pathogenesis. However, hypermethylation of CpG islands, an epigenetic event, is coming more and more into focus in carcinogenesis of the esophagus. Recent studies have proved that promoter hypermethylation of tumor suppressor genes is frequently observed in esophageal carcinomas and seems to play an important role in the pathogenesis of this tumor type. In this review, we will discuss current research on genes that are hypermethylated in human esophageal cancer and precancerous lesions of the esophagus. We will also discuss the potential use of hypermethylated genes as targets for detection, prognosis and treatment of esophageal cancer.

    1984-04-01

    Eleven common radiographic signs of mediastinal hemorrhage were evaluated by two observers for the following three patient groups: normal subjects, patients with mediastinal hemorrhage and no arterial injury, and patients with major thoracic arterial injury. Supine chest radiographs were studied in all cases. Four major conclusions can be made based upon these finding. M/C ratio (mediastinal width to chest width), tracheal deviation, left hemothorax, paraspinal line widening, and aorto-pulmonary window opacification do not reliably separate these three groups of patients. The diagnosis of mediastinal hemorrhage may be made if the aortic contour is abnormal or if one of the following signs is positive: abnormal mediastinal width, apical cap, widening of the right paratracheal stripe, or deviation of the nasogastric tube. Due to interobserver variation, there is good agreement between observers for the following four signs only: transverse mediastinal width, tracheal deviation, nasogastric tube deviation, nasogastric tube deviation, and right paratracheal stripe widening.

As patients with AIDS live longer with lower CD4 counts, gastroenterologists need to become familiar with the approach to and management of the more common lesions of the mouth and esophagus.

    The goal of this study is to evaluate the feasibility and efficacy of percutaneous transarterial embolization for the treatment of serious renal hemorrhage after renal biopsy. Nine patients with renal hemorrhage had frank pain and gross hematuria as main symptoms after renal biopsy. Intrarenal arterial injuries and perinephric hematoma were confirmed by angiography in all cases. The arterial injuries led to two types of renal hemorrhage, Type I: severe renal injure or intrarenal renal artery rupture (n=5), with contrast medium spilling out of the artery and spreading into renal pelvis or kidney capsule in angiography; Type II, pseudo aneurysm or potential risk of intrarenal artery injure (n=4), where contrast medium that spilled out of intraartery was retained in the parenchyma as little spots less than 5 mm in diameter in angiography. Transcatheter superselective intrarenal artery embolization was performed with coils or microcoils (Type I intrarenal artery injure) and polyvinyl alcohol particles (Type II injure). The intrarenal arterial injuries were occluded successfully in all patients. Light or mild back or abdominal pain in the side of the embolized kidney was found in three patients following embolization procedures and disappeared 3 days later. Serum creatinine and perinephric hematoma were stable, and gross hematuresis stopped immediately (n=4) or 3-5 days (n=3) after embolization. In conclusions, transcatheter superselective intrarenal artery embolization as a minimally invasive therapy is safe and effective for treatment of serious renal hemorrhage following percutaneous renal biopsy.

    In the present study, we used a modification of the rabbit small clot embolic stroke model (RSCEM), a multiple infarct ischemia model to achieve reperfusion (REP) through the internal carotid artery (ICA) following small clot embolization. We determined if increasing regional cortical blood flow (RCBF) following an embolic stroke is beneficial to neurological outcome. We compared this to cerebral reperfusion induced by the administration of the thrombolytic Tenecteplase (TNK, 1.5 mg/kg, IV bolus) in the presence or absence of REP. In this study, we also measured the incidence of ICH following REP and thrombolytic treatment. Following embolization, RCBF was reduced to 48-55% of baseline. When REP was induced by removal of a CCA ligature, RCBF initially increased to 185% of baseline. REP (P(50)=1.18+/-0.43 mg) had no effect on embolization-induced behavior measured 24 h following embolization compared to control (P(50)=1.01+/-0.48 mg). However, TNK treatment (2-hours post-embolization) in the absence or presence of REP (initiated 2 h following embolization) significantly (p0.05) group compared to either the control group (5.5%) or TNK group (10%). This study show that reperfusion of ICA can increase RCBF following embolization, but this is not associated with improved neurological outcome measured using quantal analysis. However, TNK administration significantly increased behavioral outcome when given 2 h following embolization; an increase that is not affected by combining TNK with REP.

    A case of cerebral hemorrhage associated with sildenafil (Revatio) use in an infant is presented. Sildenafil is increasingly used in the treatment of primary and secondary pulmonary arterial hypertension and pulmonary arteriovenous fistula. In the reported case, sildenafil used to treat pulmonary arteriovenous fistula improved right-to-left shunting across the pulmonary fistula but resulted in cerebral hemorrhage. Cerebral hemorrhage, a previously reported complication of sildenafil, developed in an infant after a rapid increase in dose, to 4.7 mg/kg/day. Therefore, sildenafil doses must be increased only with care, and cerebral hemorrhage must be considered a potential complication.

    Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

    Microscopic cerebral arterial air embolism (CAAE) has been described in many patients undergoing cardiac surgery as well as other invasive diagnostic and therapeutic procedures. However, massive CAAE is rare. We report a 42-year-old woman who initially presented with thalamic and basal ganglia hemorrhages. Shortly after a radial arterial catheter was inserted, the patient suffered a generalized seizure and CT demonstrated intra-arterial air in bilateral cerebral hemispheres. (orig.)

    A seven-month-old girl, born prematurely (birth weight 1000 g) from a twin pregnancy, was admitted to hospital due to recurrent pneumonia and atelectasis. She experienced cough and respiratory distress during feeding. The right hemithorax was smaller than the left, with diminished breath sounds and dullness. Chest x-rays revealed decreased lung volume and multiple radiolucent images in the right lung, as well as overdistention of the left lung. An esophagogram revealed three bronchial branches arising from the lower one-third of the esophagus, corresponding to the right lung and ending in a cul-de-sac. A diagnosis of esophageal lung was established. On bronchography, the right lung was absent and the trachea only continued into the left main bronchus. Echocardiography and angiotomography revealed agenesis of the pulmonary artery right branch. The surgical finding was an esophageal right lung, which was removed; the histopathological diagnosis was type II congenital pulmonary airway malformation in an esophageal lung.

    Objective:To evaluate the role of colonic interposition for reconstruction of the esophagus. Methods: From April 1979 to October 1998, Thirty-one patients with benign esophageal stenosis and 15 patients graft from the esophageal bed after the esophagus was pulled out without thoracotomy. Results: There was no perioperative death. All 31 cases of the benign esophageal stenosis got long term survival and normal life.The 3- and 5-year survival rates of patients with the carcinoma of the esophagus were 63.6% and 40. 6% respectively. Conclusion: The colonic interposition graft is a choice for the patien ts with the cervical stenosis of the esophagus, especially for those already had subtotal gastrectomy. Using the left colonic artery as the supporting vessel and using the colon segment in an isoperistaltic position is the optimal choice. Improving the operative techniques and decreasing the complications are important for the extension use of this method.

    Full Text Available Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP of 35 mmHg for 90 minutes. Serum cytokines (IL-6, KC, MCP-1, and TNF-α were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

    Lugol's solution is an iodinated agent used for treating thyroid crisis. It is primarily used in diagnostic tests for esophageal diseases. However, Lugol's solution can cause local mucosal injury and hemorrhage. We report, for the first time, a case of 34-year-old man who exhibited severe duodenal hemorrhage induced by Lugol's solution that was used to treat thyroid crisis. The quantity of Lugol's solution used for treating thyroid crisis is much higher than that used for mucosal disease investigation. Clinical practitioners should be aware of gastrointestinal hemorrhage when using Lugol's solution for the treatment of thyroid crisis.

    Full Text Available A 75-year-old man underwent endoscopic hemostatic therapy for hemorrhagic gastric ulcer in September 2002. After healing of the gastric ulcer, he underwent Helicobacter pylori eradication therapy in February 2003. In August 2007, an irregular tumor was detected in the lower esophagus at annual checkup for gastric cancer screening using X-ray. Endoscopic examination showed that the lower margin of the tumor almost coincided with the esophagogastric junction and that a short segment of Barrett’s epithelium existed near the tumor. Biopsies of the tumor showed moderately to poorly differentiated adenocarcinoma. Mild reflux esophagitis and minor hiatal hernia was also observed, and the previously treated gastric ulcer was not recurrent. Absence of H. pylori was confirmed by serum antibody and urea breath test. Surgical resection of the lower esophagus and proximal stomach was performed. The tumor invaded into the muscularis propria of the esophageal wall but had no evidence of lymph node metastasis. Based on macroscopic and pathological findings, the tumor was recognized as esophageal adenocarcinoma. Previous endoscopic examination did not detect any apparent signs of tumor in the esophagogastric junction. As far as we know, this is the first report documenting a newly developed esophageal adenocarcinoma after the successful eradication of H. pylori.

    Hemorrhage remains as one of the top 3 obstetrics related causes of maternal mortality, with most deaths occurring within 24-48 hours of delivery. Although hemorrhage related maternal mortality has declined globally, it continues to be a vexing problem. More specifically, the developing world continue to shoulder a disproportionate share of hemorrhage related deaths (99%) compared with industrialized nations (1%). Given the often preventable nature of death from hemorrhage, the cornerstone of effective mortality reduction involves risk factor identification, quick diagnosis, and timely management. In this monograph we will review the epidemiology, etiology, and preventative measures related to maternal mortality from hemorrhage.

    2007-01-01

    Bleeding from esophageal varices (EVs) is a catastrophic complication of chronic liver disease. Many years ago, surgical procedures such as esophageal transection or distal splenorenal shunting were the only treatments for EVs. In the 1970s, interventional radiology procedures such as transportal obliteration, left gastric artery embolization, and partial splenic artery embolization were introduced, improving the survival of patients with bleeding EVs. In the 1980s, endoscopic treatment, endoscopic injection sderotherapy (HS), and endoscopic variceal ligarJon (EVL), further contributed to improved survival. We combined IVR with endoscopic treatment or EIS with EVL. Most patients with EVs treated endoscopically required follow-up treatment for recurrent varices. Proper management of recurrent EVs can significantly improve patients' quality of life. Recently, we have performed EVL at 2-mo (bi-monthly) intervals for the management of EVs. Longer intervals between treatment sessions resulted in a higher rate of total eradication and lower rates of recurrence and additional treatment.

    Introduction Esophageal diverticulum, a relatively rare condition, has been considered to be associated with motor abnormalities such as conditions that cause a lack of coordination between the distal esophagus and lower esophageal sphincter. Presentation of case We herein report a case of esophageal epiphrenic diverticulum associated with diffuse esophageal spasm. A 73-year-old woman presented with dysphagia and regurgitation. Imaging examinations revealed a right-sided esophageal diverticulum located about 10 cm above the esophagogastric junction. High-resolution manometry revealed normal esophageal motility. However, 24-h pH monitoring revealed continuous acidity due to pooling of residue in the diverticulum. An esophageal epiphrenic diverticulum was diagnosed and resected thoracoscopically. Her dysphagia recurred 2 years later. High-resolution manometry revealed diffuse esophageal spasm. Discussion The diverticulum in the present case was considered to have been associated with diffuse esophageal spasm. The motility disorder was likely not identified at the first evaluation. Conclusion In this case, the patient’s symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. PMID:26143577

    Full Text Available Esophagitis is the most common disease of the esophagus. Drug use is one of the reasons of chemical esophagitis. Herein, we report two male patients of 17 and 18 years of age who developed esophagitis in acne treatment with doxycycline. Both patients took doxycycline capsules for approximately one week. Ulcerations were detected at upper and mid-esophagus of the 17-year-old patient. Circular ulcerations were found at mid-esophagus of the 18-year-old case. Doxycycline induced esophagitis is a preventable disease with the physician giving appropriate medication ingestion advice to the patient.

    A 75-year-old male, known to have achalasia, was admitted to the intensive care unit with massive upper gastrointestinal bleeding and sepsis. He had a history of purulent pericarditis 18 months earlier. He also presented with atrial fibrillation associated with a cerebral transient ischemic accident two months earlier. A contrast computed tomography scan showed an atrio-esophageal fistula with active extravasation of contrast. He was operated on via a median sternotomy, and the defects in the atrial wall, inferior vena cava and diaphragm were closed using pericardial patches. An esophagectomy was to be performed 24 hours later, but the patient died from septic shock and multiple organ failure before his second procedure.

    A 72-year old woman with a premacular subhyaloid hemorrhage could not be treated by laser photodisruption due to a thick posterior cortical vitreous. Pure sulfur hexafluoride (SF6, 0.3 mL) gas was injected intravitreally without recombinant tissue plasminogen activator, and facedown positioning was recommended for 5 days. Posterior vitreous detachment was induced and the hemorrhage dispersed into the vitreous cavity. Eight weeks later, her visual acuity had recovered from hand motions to 20/40. Fluorescein angiography revealed an arterial macroaneurysm in the inferotemporal retina. Intravitreal SF6 gas injection without recombinant tissue plasminogen activator may be an alternative method for treating a relatively new subhyaloid hemorrhage.

    Fibrovascular polyps are extremely rare benign neoplasias of the esophagus, which usually originate in the lower cricoid area. They do not produce any discomfort in the patient for a long time, however it may make itself evident by the patient's regurgitation of the polyp, producing asphyxia or, more frequently, dysphagia. The case of a 58 year old male patient is presented herein, with a 9 month record of dysphagia, weight loss and intermittent melena. The barium x-ray showed a distended esophagus, with a tumor running from the upper esophageal sphincter to the cardia. The endoscopy confirmed the presence of a pediculated tumor, implanted in the cervical esophagus. Surgeons suspected the potential malignancy of the tumor and performed a transhiatal esophagectomy. The final pathologic diagnosis was giant fibrovascular esophageal polyp.

Methods: Model with uncontrolled hemorrhagic shock was established according to modifed Wigger's describtion. Twenty-four rabbits in the model were randomly divided into 4 groups(6 in each group) ,noresuscitation(NR) group as control,N50,N60 and N70 groups with maintaining mean arterial pressure( MAP) at 50,60 and 70 mmHg respectively. The arterial blood gas analysis( ABGA) including lactic acid, base excess, arterial oxygen tension, arterial carbon dioxide tension and potential of hydrogen were detected before shock and at 0, 60,120,150,180 and 240 minutes after shock. Results:The data of ABGA of N60 group were better than those of other groups at all time-points. Conclusions: During restrictive resuscitation of the rabbits with unconrntrolled hemorrhagic shock, maintaining MAP at 60 mmHg has little effect on their ABGA. The results suggest that MAP at 60 mmHg is suitable level for the restrictive resuscitation.%目的:观察不同限制性复苏血压水平对出血未控制性休克家兔动脉血气的影响,探讨出血未控制性休克复苏时应维持的理想血压水平.方法:采用Wigger改良法制作出血未控制性休克模型,24只家兔随机分为4组(n=6).NR组:不复苏组;N50组:复苏维持平均动脉压(mean arterial pressure,MAP)在50 mmHg水平;N60组:复苏维持MAP在60 mmHg水平;N70组:复苏维持MAP在70 mmHg水平;在休克前、休克后0、60、120、150、180、240 min检测动脉血气分析,包括血乳酸、剩余碱、氧分压、二氧化碳分压、pH值等指标.结果:N60组氧分压、二氧化碳分压、乳酸、pH值在各个时间点均优于其他组(P<0.05).结论:失血性休克家兔在出血未控制前行限制性液体复苏时,维持MAP在60 mmHg对动脉

  5. Esophageal Inlet Patch

    Directory of Open Access Journals (Sweden)

    C. Behrens

    2011-01-01

    Full Text Available An inlet patch is a congenital anomaly consisting of ectopic gastric mucosa at or just distal to the upper esophageal sphincter. Most inlet patches are largely asymptomatic, but in problematic cases complications related to acid secretion such as esophagitis, ulcer, web and stricture may occur. The diagnosis of inlet patch is strongly suggested on barium swallow where the most common pattern consists of two small indentations on the wall of the esophagus. The diagnosis of inlet patch is confirmed via endoscopy with biopsy. At endoscopy, the lesion appears salmon-coloured and velvety and is easily distinguished from the normal grey-white squamous epithelium of the esophagus. The prominent margins correlate with the radiological findings of indentations and rim-like shadows on barium swallow. Histopathology provides the definitive diagnosis by demonstrating gastric mucosa adjacent to normal esophageal mucosa. No treatment is required for asymptomatic inlet patches. Symptomatic cases are treated with proton pump inhibitors to relieve symptoms related to acid secretion. Strictures and webs are treated with serial dilatation and should be biopsied to rule out malignancy.

    Aim: The origin of chest discomfort in patients with mitral valve prolapse (MVP) is controversial. Our aim was to prospectively determine the incidence of esophageal disorders in MVP patients with or without chest pain. Methods: Twenty-five MVP patients with chest pain (group A) and 25 MVP patients without chest pain (group B) underwent evaluation of esophageal motility. None of the total of 50 MVP patients had significant coronary artery disease on cardiac catheterization. Esophageal motility including esophageal mean transit time (MTT), residual fraction (RF), and retrograde index (RI) was analyzed by the radionuclide esophageal transit test (RETT). Results: In comparison with 25 age and sex-matched healthy volunteers, the results showed that: (1) 19 patients in group A (76%) had abnormal RETT findings (48% of cases with prolonged MTT, 44% of cases with higher RF, and 60% of cases with higher RI); (2) 3 patients in group B (12%) had abnormal RETT findings (8% of cases with prolonged MTT, 4% of cases with higher RF, and 8% of cases with higher RI). In addition, mean values of MTT, RF, and RI in group A patients were significantly higher than in group B patients and healthy volunteers. Conclusion: We found that the chest pain in some MVP patients may be related to abnormal esophageal motility, based on the evidence from a simple and noninvasive RETT. (orig.)

    Full Text Available Because of advances in the technology of gastrointestinal endoscopy and improvements in the quality of stents, it has become routine to place a stent as palliative therapy for malignant gastrointestinal obstruction. On the other hand, stent placement for malignant gastrointestinal hemorrhage has scarcely been reported, although it may be performed for hemorrhage of the esophageal varicose vein. We recently experienced a patient with refractory hemorrhage from an unresectable duodenal cancer who underwent placement of a self-expandable metallic stent (SEMS and thereafter had no recurrence of the hemorrhage. A 46-year-old man underwent laparotomy to radically resect a cancer in the third portion of the duodenum, which invaded widely to the superior mesenteric vein and its branches and was considered unresectable. After stomach-partitioning gastrojejunostomy was performed, chemotherapy was initiated according to the regimen of chemotherapy of far advanced gastric cancer. One year and 4 months after induction of chemotherapy, gastrointestinal hemorrhage occurred. Upper gastrointestinal endoscopy revealed the hemorrhage oozing from the duodenal cancer, and endoscopic hemostasis, such as injection of hypertonic saline epinephrine and argon plasma coagulation, was unsuccessful. Twenty days after emergence of the hemorrhage, an endoscopic covered SEMS was placed with confirmation by fluoroscopy. Immediately after placement of the stent, the tarry stool stopped and the anemia ceased to progress. The recurrence of the hemorrhage has not been confirmed without migration of the stent. SEMS is an effective hemostatic procedure for malignant refractory hemorrhage.

    Full Text Available Moyamoya disease is a cerebrovascular disease which is characterized with stenosis and occlusions at the distal part of internal carotid artery and at the proximal part of anterior and middle cerebral arteries. It rarely causes temporary or recurrent hemiparesis due to intracranial hemorrhage while symptoms like headache, convulsion, nystagmus, aphasia and ataxia may also occur. In this paper, we present a case of Moyamoya disease which was diagnosed with a 23 year old female patient who was admitted to our emergency department with headache, nausea and vomiting complaints and whose radiological findings showed occipital lobe hemorrhage.

    Objective To evaluate the safety and efficacy of pelvic arterial embolization (PAE) for treatment of primary postpartum hemorrhage (PPH), and to determine the factors associated with clinical outcomes. Methods A total of 25 patients who underwent PAE for primary PPH were retrospectively analyzed. Mode of delivery, causes of primary PPH, detailed laboratory and treatment records, and clinical outcomes were recorded. Univariate and multivariate analyses were performed to determine the factors related to clinical outcomes. Results Clinical success was achieved in 23 patients (23/25, 92.00%), the other 2 patients underwent repeat PAE. Overall bleeding control was achieved in 96.00% (24/25) patients, the other was died of hypovolemic shock after second session of PAE. Of the 23 patients with long-term follow-up, 23 (100%) restarted regular menstruation, and 4 became pregnant. Univariate analysis showed that caesarean section delivery, associated disseminated intravascular coagulation (DIC), and massive transfusion more than 10 red blood cell units were related to a high rate of clinical failure. Multivariate analysis showed that associated DIC and massive transfusion were signiifcantly related to clinical failure.Conclusions PAE for primary PPH is safe and effective, with bleeding control successfully after PAE observed in 96.00% of patients. Patients with associated DIC and massive transfusion were likely to need careful observation after PAE.%目的:讨论盆腔动脉栓塞术(PAE)治疗难治性产后大出血(PPH)的安全性和可行性,并评估影响其临床成功率的因素。方法回顾性分析需要做PAE手术的25例难治性PPH患者,分娩方式、出血的病因、详细的生化资料和治疗措施及临床结果都被记录下来,对影响临床结果的各种可能因素进行了单变量及多变量分析。结果临床成功率为92.00%(23/25),其余2例需要再次栓塞。产后出血控制成功率为96.00%(24/25

    Cancer of the esophagus is an underestimated, poorly understood, and changing disease. Its overall 5-year survival is less than 20%, even in the United States, which is largely a function of a delay in diagnosis until its more advanced stages. Additionally, the epidemiologic complexities of esophageal cancer are vast, rendering screening and prevention limited at best. First, the prevalence of esophageal cancer is unevenly distributed throughout the world. Second, the two histological forms (squamous cell and adenocarcinoma) vary in terms of their geographic prevalence and associated risk factors. Third, some populations appear at particular risk for esophageal cancer. And fourth, the incidence of esophageal cancer is in continuous flux among groups. Despite the varied prevalence and risks among populations, some factors have emerged as consistent associations while others are only now becoming more fully recognized. The most prominent, scientifically supported, and long-regarded risk factors for esophageal cancer are tobacco, alcohol, and reflux esophagitis. Inasmuch as the above are regarded as important risk factors for esophageal cancer, they are not the sole contributors. Dietary habits, nutrition, local customs, and the environment may be contributory. Along these lines, vitamins, minerals, fruits, vegetables, meats, fats, salted foods, nitrogen compounds, carcinogens, mycotoxins, and even the temperature of what we consume are increasingly regarded as potential etiologies for this deadly although potentially preventable disease. The goal of this review is to shed light on the less known role of nutrition and dietary habits in esophageal cancer.

    2016-05-15

    Here, we report a case of a 30-year-old woman who presented with primary postpartum hemorrhage due to uterine atony. She received uterine artery embolization (UAE). During left internal iliac arteriography, an aberrant left ovarian artery originating from the left iliolumbar artery was visualized. The aberrant left ovarian artery was connected to the left uterine artery via prominent collateral vessels. It supplied a significant amount of blood to the fundus of the uterus. Bilateral hypertrophied uterine arteries were embolized very carefully so that the embolic material did not reflux into the aberrant left ovarian artery. After the procedure, her vaginal bleeding was successfully controlled. Accurate understanding of anatomical variations of the ovarian artery is essential to avoid failure in controlling postpartum hemorrhage with UAE.

    Simple prepatellar bursitis is easily diagnosed both clinically and by MRI. MRI shows the typical T1 and T2 lengthening of fluid within the bursa. However, because of complex MRI appearance of hemorrhage, chronic hemorrhagic bursitis and the size of the prepatellar mass the clinical and MRI appearance can be very different. (orig.)

  14. Gender effects on esophageal motility

    Full Text Available It has been suggested that there are no gender effects on esophageal motility. However, in previous studies the subjects did not perform multiple swallows and the quantitative features of esophageal contractions were not evaluated. In order to investigate the gender effects on esophageal motility we studied 40 healthy normal volunteers, 20 men aged 37 ± 15 years (mean ± SD, and 20 women aged 38 ± 14 years. We used the manometric method with an eight-lumen polyvinyl catheter and continuous perfusion. The upper and lower esophageal sphincter pressures were measured by the rapid pull-through method. With the catheter positioned with one lumen opening in the lower esophageal sphincter, and the others at 5, 10 and 15 cm above the sphincter, ten swallows of a 5-ml water bolus alternated with ten dry swallows were performed. Statistical analysis was done by the Student t-test and Mann-Whitney test. Gender differences (P<0.05 were observed for wet swallows in the duration of contractions 5 cm above the lower esophageal sphincter (men: 3.7 ± 0.2 s, women: 4.5 ± 0.3 s, mean ± SEM, and in the velocity of contractions from 15 to 10 cm above the lower esophageal sphincter (men: 4.7 ± 0.3 cm/s, women: 3.5 ± 0.2 cm/s. There was no difference (P>0.05 in sphincter pressure, duration and percentage of complete lower esophageal sphincter relaxation, amplitude of contractions, or in the number of failed, multipeaked and synchronous contractions. We conclude that gender may cause some differences in esophageal motility which, though of no clinical significance, should be taken into consideration when interpreting esophageal motility tests.

    Gastroesophageal reflux disease is a widespread among population in economically developed countries including Russia. It was analyzed the results of 34 903 endoscopic examinations of upper gastrointestinal tract in ethnically and socially homogeneous population of Leningrad region with symptoms of gastric dispepsia. Procedures were performed for the period 2007-2013. Prevalence of erosive esophagitis was 4.9%. Peptic esophageal strictures due to chronic reflux-associated inflammation were revealed in 0.2% of examined patients (3.7% of patients with erosive esophagitis). Obtained data allow to considergastroesophageal reflux disease as a socially significant problem in Russia requiring close attention and further study.

    2012-01-01

    Although most cases of acute nonvariceal gastrointestinal hemorrhage either spontaneously resolve or respond to medical management or endoscopic treatment,there are still a significant number of patients who require emergency angiography and transcatheter treatment.Evaluation with noninvasive imaging such as nuclear scintigraphy or computed tomography may localize the bleeding source and/or confirm active hemorrhage prior to angiography.Any angiographic evaluation should begin with selective catheterization of the artery supplying the most likely site of bleeding,as determined by the available clinical,endoscopic and imaging data.If a hemorrhage source is identified,superselective catheterization followed by transcatheter microcoil embolization is usually the most effective means of successfully controlling hemorrhage while minimizing potential complications.This is now wellrecognized as a viable and safe alternative to emergency surgery.In selected situations transcatheter intra-arterial infusion of vasopressin may also be useful in controlling acute gastrointestinal bleeding.One must be aware of the various side effects and potential complications associated with this treatment,however,and recognize the high re-bleeding rate.In this article we review the current role of angiography,transcatheter arterial embolization and infusion therapy in the evaluation and management of nonvariceal gastrointestinal hemorrhage.

    @@INTRODUCTION Esophageal hematomas develop from the dissection of the mucosa from the muscular layers of the esophageal wall and represent an uncommon condition affecting all ages[t-3]. Although the most common cause of esophageal hematomas is iatrogenic mechanical injury-induced by prolonged nasogastric intubation, difficult or forceful endoscopic intubation, or the result of variceal injection sclerotherapy- some may be spontaneous,particularly in patients receiving anticoagulants[3-6]. Presenting symptoms most commonly include dysphagia, hematemesis, and sub-sternal or epigastric pain[5,9].

    2011-01-01

    Full Text Available Purpose. Formation of a tracheoinnominate artery fistula (TIF and consecutive hemorrhage is a rare and life-threatening complication with high mortality. Warning symptoms can be absent. The current literature contains only few considerations for misleading signs, especially in cases where the contact between the tissue and the cannula is tight. Method and Results. We report two cases of life-threatening hemorrhages that appeared six days and two months after percutaneous dilatational tracheostomy (PDT in two patients, respectively. In these cases, diagnosis of tracheoinnominate artery fistula (TIF was difficult. Tracheal ring fracture after PDT and pressure ulceration caused by cannula were implicated in TIF formation. The cannula was overblocked to buy time before surgical closure. Both patients survived without any additional neurological deficiency. Conclusion. Massive hemorrhage in patients after tracheostomy is likely due to TIF. Ultrasound scanning before PDT and careful periodical followup of the trachea are required.

    Summary Arterial fenestrations are an anatomic variant with indeterminate significance. Given the controversy surrounding fenestrations we sought their prevalence within our practice along with their association with other cerebrovascular anomalies. We retrospectively reviewed 10,927 patients undergoing digital subtraction angiography between 1992 and 2011. Dictated reports were searched for the terms “fenestration” or “fenestrated” with images reviewed for relevance, yielding 228 unique cases. A Medline database search from February 1964 to January 2013 generated 304 citations, 127 cases of which were selected for analysis. Cerebral arterial fenestrations were identified in 228 patients (2.1%). At least one aneurysm was noted in 60.5% of patients, with an aneurysm arising from the fenestration in 19.6% of patients. Aneurysmal subarachnoid hemorrhage or non-aneurysmal subarachnoid hemorrhage were present in 60.1% and 15.8%, respectively. For the subset of patients with an aneurysm arising directly from a fenestration relative to those patients with an aneurysm not immediately associated with a fenestration, the prevalence of aneurysmal subarachnoid hemorrhage was 66.7% vs. 58.6% (p = 0.58). Fenestrations were more often within the posterior circulation (73.2%) than the anterior circulation (24.6%), though there was no difference in the prevalence of aneurysms within these groups (61.1% vs. 60.7%, p = 1.0). Cerebral arterial fenestrations are an anatomic variant more often manifesting at the anterior communicating arterial complex and basilar artery and with no definite pathological relationship with aneurysms.

    AIM: To report present state of iatrogenic drug-induced esophageal injury (DIEI) induced by medications in a private clinic.METHODS: Iatrogenic drug-induced esophageal injury (DIEI) induced by medications has been more frequently reported. In a private clinic we encountered 36 cases of esophageal ulcerations complicating doxycycline therapy in a mainly younger Saudi population (median age 29 years).RESULTS: The most frequent presenting symptoms were oclynophagia, retrostemal burning pain and dysphagia (94 %,75 % and 56 %, respectively). The diagnosis was according to medical history and confirmed by endoscopy in all patients.Beside withdrawal of doxycycline, when feasible, all patients were treated with a proton-pump inhibitor (PPI) and a prokinetic. Thirty patients who reported to the clinic after treatment were improved within 1-7 (median 1.7) days.CONCLUSION: Esophageal ulceration has to be suspected in younger patients with odynophagia, retrosternal burning pain and/or clysphagia during the treatment with doxycycline.

    The aim of the present study was to investigate esophageal motor function by means of krypton-81m esophageal transit scintigraphy and to compare the results with the functional and morphological data obtained by means of triple lumen manometry and endoscopy. In acute and subacute stages of the disease, all clinical, anatomical, and functional parameters were in good agreement, revealing significant impairment. In chronic stages, the severity of the dysphagia was not correlated to the importance of the residual stenosis. Conversely, 81mKr esophageal transit and manometric's findings were in good agreement with the clinical symptoms, during the entire follow-up period ranging between 3 months to 7 years. The 81mKr test is undoubtedly the easiest and probably the most physiological technique currently available for long-term functional evaluation of caustic esophagitis.

The mean interval between the two bleeding episodes was 44.6 ± 12.5 months. The 73.3%patients were hypertensive .′The site of the first hemorrhage was ganglionic in 8 patients , ]ohar in six paients and brainstem in one .The recurrent hemorrhage occurred at a different location from the previous ICH.The most common pattern of recurrence was “ganglionic -ganglionic” (7 patients), lobar - ganglionic (3 patients), lobar-lobar(three patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor. By comparison with 24 patients followed up to average 47.5± 18.7 months with isolated ICH without recurrence .Only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanism of recurrence of ICH were multiple(hypertension, cerebral amyloid angiopathy).Contral of blood pressure and good living habit after the first hemorrhage may prevent ICH recurrences.

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

    Esophageal cancer is mainly found in Asia and east Africa and is one of the deadliest cancers in the world.However,it has not garnered much attention in the Western world due to its low incidence rate.An increasing amount of data indicate that esophageal cancer,particularly esophageal adenocarcinoma,has been rising by 6-fold annually and is now becoming the fastest growing cancer in the United States.This rise has been associated with the increase of the obese population,as abdominal fat puts extra pressure on the stomach and causes gastroesophageal reflux disease (GERD).Long standing GERD can induce esophagitis and metaplasia and,ultimately,leads to adenocarcinoma.Acid suppression has been the main strategy to treat GERD; however,it has not been proven to control esophageal malignancy effectively.In fact,its side effects have triggered multiple warnings from regulatory agencies.The high mortality and fast growth of esophageal cancer demand more vigorous efforts to look into its deeper mechanisms and come up with better therapeutic options.

    To demonstrate the clinical usefulness of ultrasonography for detecting esophageal varices. In 20 cases of esophaged varix, the authors analysed the transabdominal ultrasonographic findings of the esophagogastric junction and compared mural thickness, the anteroposterior diameter of the esophagus, and the echogenic nature of the esophageal mucosal layer with those of 78 normal patients. The anterior and posterior mural thickeness of normal esophagus was 2.2{+-}0.7 and 2.4{+-}0.8mm respectively, but for variceal esophagus, the corresponding readings were 5.9{+-}1.3 and 5.2{+-}1.3mm respectively. The anteroposterior diameter of normal esophagus was 7.9{+-}2.1mm and that of variceal esophagus was 14.0{+-}1.8mm. There was a stastically significant difference (p<0.01) in mural thickness and anteroposterior diameter of the esophagus between a normal and variceal patient with regard to change of echogenic nature at the esphagogastric junction. Normal esophageal mucosa showed a thin and uniform echogenic line, but for variceal mucosa, the echogenic pattern was irregular, tortuous and thick. The athors believe that transabdominal US is helpful for detecting esophageal varices in patients with liver cirrhosis and UGI bleeding. Important clinically useful sonographic findings in diagnosing esophageal varix are as follows:1) mural thickness more than 6mm; 2) anteroposterior diameter of the esophagus of more than 15mm;3) irregular, tortuous and thickened echogenic mucosa.

    This study reports cerebral angiographic findings observed after stent retriever thrombectomy that is suggestive of a higher risk of hemorrhagic transformation (HT). A woman aged 65-75 presented with a right middle cerebral artery syndrome confirmed by non-contrast CT brain scan. Endovascular revascularization using the Solitaire device was placed across the thromboembolic occlusion and thromboembolectomy was performed. Angiography showed complete recanalization of the left internal carotid artery, anterior and middle cerebral artery branches. Twelve hours following the procedure the patient had a hemorrhagic conversion of the ischemic infarct with significant mass effect causing herniation. Despite surgical intervention (hemicraniectomy) the patient died. The angiographic features following revascularization of the vessels distal to the occlusion showed subtle dilations which were visualized at the branch points of the vessels. This may be a warning sign of increased risk of HT.

    Full Text Available Endoscopic submucosal dissection (ESD for the treatment of esophageal mucosal lesions is associated with a risk of esophageal stenosis, especially for near-circumferential or circumferential esophageal mucosal defects. Here, we review historic and modern studies on the prevention and treatment of esophageal stenosis after ESD. These methods include prevention via pharmacological treatment, endoscopic autologous cell transplantation, endoscopic esophageal dilatation, and stent placement. This short review will focus on direct prevention and treatment, which may help guide the way forward.

    AIM To treat esophageal stricture secondary to the ingestion of corrosive materials in children using theileocolon with ileocecal valve as a substitute for esophagus.METHODS Between 1992 and 1999, isoperistaltic retrosternal ileocolic esophageal replacements wereperformed in 12 patients; 50 cadavers were studied to observe the vascularity in the ileocolic region andmetabolic indexes were measured before and after surgery or between the operative group and the normalcontrols in 20 piglet models.RESULTS A follow-up of 3 years in the 12 cases found no death in intra- and post- operative periodclinically. Cervical ileoesophageal anastomotic leaks occurred in 2 cases. The distribution pattern of venousvessel in the ileocolic region was far more constant than that of the artery. The arrangements of artery in theileocolic segment were classified into 7 types, and there was no interruption of paracolic anastomosis betweenarteries. The resections of 50 cm terminal ileum, cecum and 50 cm ascending colon affected enterohepaticcirculation of bile acid (bile salt) and the fatty metabolism in early period after surgery in piglet models.Shortening of the time and reducing of the area for water absorption after ileocolic resection resulted indiarrhea in piglet models. The loss of “bacterial barrier” role of ileocecal valve led to bacteria immigrationfrom colon to ileum and small intestinal bacterial overgrowth.CONCLUSION The ileocolic esophageal replacement taking advantage of antireflux role of the ileocecalvalve has obtained satisfactory effect. To understand the characteristics of the patterns of arteries and veinsdistribution and physiological functions of the ileocolic segment is useful in guiding clinical practice andpostoperative management and preventing postoperative complications as well.

    Full Text Available This paper aimed to define the origin and distribution of the celiac artery and its collateral branches in 15 fowls from the Columba livia species, which were obtained from the Zoonosis Control Center of Brasilia, Brazil. In order to mark the arterial system of the specimens, the left brachiocephalic trunk was canullated and a colored water-latex solution was injected there. Afterwards, fowls were fixed in a 10% v/v formaldehyde solution and dissected with appropriate equipment, presenting the results described in this paper. The celiac artery originated from the ventral face of the descendent aorta. The first collateral branch arose from the celiac artery itself, forming the esophageal artery. Then, the celiac artery has bifurcated into two branches, named left and right branches of the celiac artery. The left branch emitted the proventricular ventral artery, followed by the splenic arteries, proventricular dorsal artery, and the left hepatic artery. The left branch has bifurcated into two branches, known as ventral and left gastric arteries. The right branch emitted the right hepatic artery, followed by the ileal artery and the right gastric artery. Finally, the right branch turned into the pancreaticoduodenal artery. Our findings showed a great similarity with the avian lineages of the Gallus gallus species, except for the lack of ileocecal artery, cystic branches, and dorsal gastric artery.

    At Digestive Disease Week (DDW) 2014, developments in esophageal disease were presented. Highlights include: the usefulness of impedancemetry to diagnose reflux disease, or the effectiveness of PPIs for treating non-cardiac chest pain. Concerning Barrett's esophagus, its prevalence is identical in patients with and without reflux symptoms, Barrett segments less than 1cm probably do not require follow-up, and in older patients with long-segment Barrett, initial endoscopies overlooked up to 2% of significant lesions. Regarding achalasia, surgical myotomy is no more effective than endoscopic dilation and may even be less effective than peroral endoscopic myotomy (POEM). In terms of eosinophilic esophagitis, it is important to systematically take biopsies in patients with dysphagia so that cases of eosinophilic esophagitis are not overlooked. In addition, for this condition, routine endoscopic dilations not only do not seem useful in improving the course of the disease, but could also worsen the response to medical treatment.

    2004-01-01

    We conducted a retrospective study of 6,966 patients who had undergone tonsillectomy or adenotonsillectomy to evaluate the incidence and clinical features of previously unidentified coagulation disorders in patients who experienced postoperative hemorrhage (n = 201). We found that post-tonsillectomy hemorrhage secondary to unidentified coagulation disorders is extremely rare. However, normal coagulation values and an insignificant history do not rule out coagulation disorders. If diffuse, persistent, and bilateral bleeding is not related to arterial hypertension, dissection technique, or local infection, a rapid and detailed analysis of coagulation factors should be considered.

    A number of congenital and acquired disorders require esophageal tissue replacement.Various surgical techniques,such as gastric and colonic interposition,are standards of treatment,but frequently complicated by stenosis and other problems.Regenerative medicine approaches facilitate the use of biological constructs to replace or regenerate normal tissue function.We review the literature of esophageal tissue engineering,discuss its implications,compare the methodologies that have been employed and suggest possible directions for the future.Medline,Embase,the Cochrane Library,National Research Register and ClinicalTrials.gov databases were searched with the following search terms:stem cell and esophagus,esophageal replacement,esophageal tissue engineering,esophageal substitution.Reference lists of papers identified were also examined and experts in this field contacted for further information.All full-text articles in English of all potentially relevant abstracts were reviewed.Tissue engineering has involved acellular scaffolds that were either transplanted with the aim of being repopulated by host cells or seeded prior to transplantation.When acellular scaffolds were used to replace patch and short tubular defects they allowed epithelial and partial muscular migration whereas when employed for long tubular defects the results were poor leading to an increased rate of stenosis and mortality.Stenting has been shown as an effective means to reduce stenotic changes and promote cell migration,whilst omental wrapping to induce vascularization of the construct has an uncertain benefit.Decellularized matrices have been recently suggested as the optimal choice for scaffolds,but smart polymers that will incorporate signalling to promote cell-scaffold interaction may provide a more reproducible and available solution.Results in animal models that have used seeded scaffolds strongly suggest that seeding of both muscle and epithelial cells on scaffolds prior to implantation is a

    Recent success with thrombolytic therapy for acute myocardial infarction has stimulated interest in its use for stroke. To determine the hemorrhagic potential of thrombolytic therapy in experimental cerebral infarction, we compared a group of tissue plasminogen activator-treated rabbits (n = 4) with 2 groups of streptokinase-treated rabbits (n = 6 in each), as well as with 3 groups of heparin-treated rabbits (n = 5 in each) and untreated controls (n = 12). Focal cerebral infarction was produced in rabbits by occlusion of the right common carotid and middle cerebral arteries coupled with 2 hours of halothane-induced hypotension. Treatment with heparin or thrombolytic agents began 24 hours after occlusion. One additional group was treated with streptokinase 1 hour after occlusion (n = 6) to determine the hemorrhagic potential of thrombolytic agents in evolving infarction. Rabbits were killed 29-33 hours after occlusion, and brain sections were examined using light microscopy. The results demonstrate that microscopic hemorrhage is frequently present in infarcted tissue irrespective of treatment. Gross cerebral hemorrhage did not occur in untreated rabbits or in rabbits treated with streptokinase 1 hour after occlusion. Only rabbits treated with streptokinase, tissue plasminogen activator, or excessive doses of heparin 24 hours after occlusion, at a time when cerebral infarction was well established, exhibited gross hemorrhage in the area of infarction. These data suggest that treatment of ischemic stroke with thrombolytic agents carries an increased risk of cerebral hemorrhage unless the agents are given early after the onset of symptoms.

    Full Text Available A seven-month-old girl, born prematurely (birth weight 1000 g from a twin pregnancy, was admitted to hospital due to recurrent pneumonia and atelectasis. She experienced cough and respiratory distress during feeding. The right hemithorax was smaller than the left, with diminished breath sounds and dullness. Chest x-rays revealed decreased lung volume and multiple radiolucent images in the right lung, as well as overdistention of the left lung. An esophagogram revealed three bronchial branches arising from the lower one-third of the esophagus, corresponding to the right lung and ending in a cul-de-sac. A diagnosis of esophageal lung was established. On bronchography, the right lung was absent and the trachea only continued into the left main bronchus. Echocardiography and angiotomography revealed agenesis of the pulmonary artery right branch. The surgical finding was an esophageal right lung, which was removed; the histopathological diagnosis was type II congenital pulmonary airway malformation in an esophageal lung.

    Objective To assess the diagnostic value for gastrointestinal hemorrhage senile patients with potential coronary artery disease using 320-row coronary angiography with CT (CTA). Methods A total of 71 gastrointestinal bleeding senile patients without coronary heart disease (CHD) history were successively accepted conventional 12-director electrocardiogram (ECG) and 320-row CTA in two weeks from being admitted to hospital. Among those patients, 26 accepted the X-ray coronary angiography (CAG) examination in six weeks. The diagnostic values of each method were compared in diagnosing gastrointestinal hemorrhage patients with potential coronary artery disease. Results In all 71 patients, 29 (40.84%) who positive coronary heart disease (CHD) test results were obtained using 320-row CTA and only 19 ( 26. 76% ) were gotten using ECG. There was statistical significance between the two methods ( P 0.05 ) . For diagnosing CHD, CTA gained an accuracy of 96.15% ( sensitivity 100% and specificity 90. 91 % ).

    A 75-year old man had been diagnosed at 42 years of age as having polycythemia vera and had been monitored at another hospital.Progression of anemia had been recognized at about age 70,and the patient was thus referred to our center in 2008 where secondary myelofibrosis was diagnosed based on bone marrow biopsy findings.Hematemesis due to rupture of esophageal varices occurred in January and February of 2011.The bleeding was stopped by endoscopic variceal ligation.Furthermore,in March of the same year,hematemesis recurred and the patient was transported to our center.He was in irreversible hemorrhagic shock and died.The autopsy showed severe bone marrow fibrosis with mainly argyrophilic fibers,an observation consistent with myelofibrosis.The liver weighed 1856 g the spleen 1572 g,indicating marked hepatosplenomegaly.The liver and spleen both showed extramedullary hemopoiesis.Myelofibrosis is often complicated by portal hypertension and is occasionally associated with gastrointestinal hemorrhage due to esophageal varices.A patient diagnosed as having myelofibrosis needs to be screened for esophageal/gastric varices.Myelofibrosis has a poor prognosis.Therefore,it is necessary to carefully decide the therapeutic strategy in consideration of the patient's concomitant conditions,treatment invasiveness and quality of life.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    A prospective radiologic-endoscopic study of the esophagogastric region in 266 patients, including 206 normals and 60 with esophagitis, is reported. The endoscopic classification grading severity of esophagitis was grade 1-normal; grades 2. 3. and 4-mild, moderate, and severe esophagitis, respectively. Radiology detected 22% of patient with mild esophagitis, 83% with moderate esophagitis, and 95% with severe esophagitis. Although hiatal hernia was present in 40% of normals and 89% with esophagitis, absence of radiographic hiatal hernia excluded esophagitis with 95% accuracy. The implications of this study regarding the role of radiology in evaluating patient with suspected reflux esophagitis are discussed.

    2017-01-01

    Background/Aims Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particularly in the lower esophageal sphincter. In this study we evaluated esophageal transit times in patients of primary hypothyroidism using the technique of radionuclide esophageal transit scintigraphy. Methods Thirty-one patients of primary hypothyroidism and 15 euthyroid healthy controls were evaluated for esophageal transit time using 15–20 MBq of Technetium-99m sulfur colloid diluted in 10–15 mL of drinking water. Time activity curve was generated for each study and esophageal transit time was calculated as time taken for clearance of 90% radioactive bolus from the region of interest encompassing the esophagus. Esophageal transit time of more than 10 seconds was considered as prolonged. Results Patients of primary hypothyroidism had a significantly increased mean esophageal transit time of 19.35 ± 20.02 seconds in comparison to the mean time of 8.25 ± 1.71 seconds in healthy controls (P hypothyroidism may have subclinical esophageal dysmotility with prolonged esophageal transit time which can be reversible by thyroxine treatment. Prolonged esophageal transit time in primary hypothyroidism may correlate with serum thyroid stimulating hormone levels. PMID:27444283

    BACKGROUND: Cerebral hemorrhage can cause the imbalance of nerve function, whereas its mechanism and main impact factors are still not quite clear.OBJECTIVE: To explore the rules about the changes of intracranial pressure in brainstem hemorrhage and internal capsule hemorrhage, and analyze the role of intracranial hypertension in the changes of nerve function caused by cerebral hemorrhage.DESIGN: A self-controlled trial.SETTING: Department of Physiology, Tianjin Medical University.MATERIALS: Sixty-five healthy male Japanese white rabbits with long ears (1.5-1.8 kg) were supplied and fed by the Department of Animal Experiment of Tianjin Medical University. The RM6240B biological signal collecting and processing system was used.METHODS: The experiments were conducted in the Department of Physiology, Tianjin Medical University from August 2001 to May 2006. ① The rabbits were anesthetized, then fixed onto the brain stereotaxic apparatus, and afterwards fenestration on skull and intubation to lateral ventricle were performed. The dynamic changes of intracranial pressure were monitored continuously. Rabbits were infused with autologous arterial blood (0.3 mL) into midbrain corpora quadrigemina inferior colliculus to induce model of acute brainstem hemorrhage; models of internal capsule hemorrhage were established by infusing autologous arterial blood into internal capsule. ② The dynamic intracranial pressures under the above conditions were recorded continuously with the RM6240B biological signal collecting and processing system. ③ An animal model of persistent intracranial hypertension was established by infusion of physiologic saline into lateral ventricle. ④ The changes of the intensity of autonomic nerve discharge were analyzed, using the biological signal collecting and processing system before and after hemorrhage and under persistent intracranial hypertension. ⑤ Ten animal models of internal capsule hemorrhage and 10 of brainstem hemorrhage were selected

    2015-01-01

    Full Text Available Recent data indicate that in patients with hereditary hemorrhagic teleangiectasia (HHT, low iron levels due to inadequate replacement after hemorrhagic iron losses are associated with elevated factor-VIII plasma levels and consecutively increased risk of venous thrombo-embolism. Here, we report a patient with HHT, low iron levels, elevated factor-VIII, and recurrent venous thrombo-embolism. A 64-year-old multimorbid Serbian gipsy was diagnosed with HHT at age 62 years. He had a history of recurrent epistaxis, teleangiectasias on the lips, renal and pulmonary arterio-venous malformations, and a family history positive for HHT. He had experienced recurrent venous thrombosis (mesenteric vein thrombosis, portal venous thrombosis, deep venous thrombosis, insufficiently treated with phenprocoumon during 16 months and gastro-intestinal bleeding. Blood tests revealed sideropenia and elevated plasma levels of coagulation factor-VIII. His history was positive for diabetes, arterial hypertension, hyperlipidemia, smoking, cerebral abscess, recurrent ischemic stroke, recurrent ileus, peripheral arterial occluding disease, polyneuropathy, mild renal insufficiency, and epilepsy. Following recent findings, hypercoagulability was attributed to the sideropenia-induced elevation of coagulation factor-VIII. In conclusion, HHT may be associated with hypercoagulability due to elevated factor-VIII associated with low serum iron levels from recurrent bleeding. Iron substitution may prevent HHT patients from hypercoagulability.

    Full Text Available Hemorrhagic shock and resuscitation induces pulmonary inflammation that leads to acute lung injury. Biliverdin, a metabolite of heme catabolism, has been shown to have potent cytoprotective, anti-inflammatory, and anti-oxidant effects. This study aimed to examine the effects of intravenous biliverdin administration on lung injury induced by hemorrhagic shock and resuscitation in rats. Biliverdin or vehicle was administered to the rats 1 h before sham or hemorrhagic shock-inducing surgery. The sham-operated rats underwent all surgical procedures except bleeding. To induce hemorrhagic shock, rats were bled to achieve a mean arterial pressure of 30 mmHg that was maintained for 60 min, followed by resuscitation with shed blood. Histopathological changes in the lungs were evaluated by histopathological scoring analysis. Inflammatory gene expression was determined by Northern blot analysis, and oxidative DNA damage was assessed by measuring 8-hydroxy-2' deoxyguanosine levels in the lungs. Hemorrhagic shock and resuscitation resulted in prominent histopathological damage, including congestion, edema, cellular infiltration, and hemorrhage. Biliverdin administration prior to hemorrhagic shock and resuscitation significantly ameliorated these lung injuries as judged by histopathological improvement. After hemorrhagic shock and resuscitation, inflammatory gene expression of tumor necrosis factor-α and inducible nitric oxide synthase were increased by 18- and 8-fold, respectively. Inflammatory gene expression significantly decreased when biliverdin was administered prior to hemorrhagic shock and resuscitation. Moreover, after hemorrhagic shock and resuscitation, lung 8-hydroxy-2' deoxyguanosine levels in mitochondrial DNA expressed in the pulmonary interstitium increased by 1.5-fold. Biliverdin administration prior to hemorrhagic shock and resuscitation decreased mitochondrial 8-hydroxy-2' deoxyguanosine levels to almost the same level as that in the

    Anabolic steroid abuse is common among athletes and is associated with a number of medical complications. We describe a case of a 27-year-old male bodybuilder with multiple hepatic adenomas induced by anabolic steroids. He initially presented with tumor hemorrhage and was treated with left lateral hepatic segmentectomy. Regression of the remaining tumors was observed with cessation of steroid use. However, 3 years and a half alter his initial hepatic segmentectomy, he presented with recurrent tumor enlargement and intraperitoneal hemorrhage in the setting of steroid abuse relapse. Given his limited hepatic reserve, he was conservatively managed with embolization of the right accessory hepatic artery.This is the first reported case of hepatic adenoma re-growth with recidivistic steroid abuse, complicated by life-threatening hemorrhage. While athletes and bodybuilders are often aware of the legal and social ramifications of steroid abuse, they should continue to be counseled about its serious medical risks.

  6. Distal esophageal spasm: an update.

    Science.gov (United States)

    Achem, Sami R; Gerson, Lauren B

    2013-09-01

    Distal esophageal spasm (DES) is an esophageal motility disorder that presents clinically with chest pain and/or dysphagia and is defined manometrically as simultaneous contractions in the distal (smooth muscle) esophagus in ≥20% of wet swallows (and amplitude contraction of ≥30 mmHg) alternating with normal peristalsis. With the introduction of high resolution esophageal pressure topography (EPT) in 2000, the definition of DES was modified. The Chicago classification proposed that the defining criteria for DES using EPT should be the presence of at least two premature contractions (distal latencylong acting), calcium-channel blockers, anticholinergic agents, 5-phosphodiesterase inhibitors, visceral analgesics (tricyclic agents or SSRI), and esophageal dilation. Acid suppression therapy is frequently used, but clinical outcome trials to support this approach are not available. Injection of botulinum toxin in the distal esophagus may be effective, but further data regarding the development of post-injection gastroesophageal reflux need to be assessed. Heller myotomy combined with fundoplication remains an alternative for the rare refractory patient. Preliminary studies suggest that the newly developed endoscopic technique of per oral endoscopic myotomy (POEM) may also be an alternative treatment modality.

    There have been many new developments in our understanding of esophageal carcinoma biology over the past several years. Information regarding both of the major forms of this disease, adenocarcinoma and squamous cell carcinoma, has accumulated in conjunction with data on precursor conditions such as Barrett's esophagus. Interesting and promising findings have included overexpression of proto-oncogenes,loss of heterozygosity at multiple chromosomal loci, tumor suppressor gene inactivation, epigenetic silencing by DNA methylation, and mutations and deletions involving the tumor suppressor gene p53. Important cancer pathways, the cyclin kinase inhibitor cascade and the DNA mismatch repair process, implicated in the genesis of multiple tumor types have also been inculpated in esophageal carcinogenesis. Alterations in the p16 and p15 cyclin kinase inhibitors including point mutations and homozygous deletions have been reported in primary esophageal tumors. Further developments in the field of molecular carcinogenesis of esophageal malignancies promise to yield improvements in prevention, early detection, prognostic categorization, and perhaps gene-based therapy of this deadly disease.

    Dual antiplatelet therapy consisting of low-dose aspirin (LDA) and other antiplatelet medications is recommended in patients with coronary heart disease, but it may increase the risk of esophageal lesion and bleeding.We describe a case of esophageal mucosal lesion that was difficult to distinguish from malignancy in a patient with a history of ingesting LDA and prasugrel after implantation of a drug-eluting stent. Multiple auxiliary examinations were performed to make a definite diagnosis. The patient recovered completely after concomitant acid-suppressive therapy. Based on these findings, we strongly argue for the evaluation of the risk of gastrointestinal mucosal injury and hemorrhage if LDA therapy is required, and we stress the paramount importance of using drug combinations in individual patients.

    Full Text Available Background: Moyamoya disease (MMD in adults often manifests with hemorrhage. Combined revascularization in hemorrhagic MMD is controversial as improvement in hemodynamics may be offset by hypervascularity-induced rebleeding. Aim: Long-term outcome assessment of adult patients from non-endemic region with hemorrhagic MMD undergoing combined revascularization. Setting: Tertiary care, academic setting. Materials and Methods: Both Suzuki′s internal carotid artery (ICA grade (1-6 and Mugikura′s posterior cerebral artery (PCA grade (1-4 were applied to 11 patients with hemorrhagic MMD (mean symptom duration 6.11±6.46 months undergoing direct [superficial temporal artery-middle cerebral artery (STA-MCA bypass] and indirect encephalomyosynangiosis (EMSA revascularization. They were clinically graded at follow-up (F/U as: excellent, preoperative symptoms resolved; good, preoperative symptoms resolved, neurological deficits remained; fair, symptom frequency decreased; and poor, symptoms unchanged/worsened. Digital subtraction angiogram/magnetic resonance angiography (DSA/MRA assessed the patency of anastomosis and cerebral hemodynamics as: 0 = non-patent; 1 = patent bypass, STA perfused recipient artery, moyamoya vessels unchanged; and, 2 = patent bypass, STA widely perfused MCA territory, moyamoya vessels diminished.

    Chronic postoperative neuralgias and headache following retrosigmoid craniotomy can be uncomfortable for the patient. We aimed to better elucidate the regional nerve anatomy in an effort to minimize this postoperative complication. Ten adult cadaveric heads (20 sides) were dissected to observe the relationship between the lesser occipital nerve and a traditional linear versus modified U incision during retrosigmoid craniotomy. Additionally, the relationship between these incisions and the occipital artery were observed. The lesser occipital nerve was found to have two types of course. Type I nerves (60%) remained close to the posterior border of the sternocleidomastoid muscle and some crossed anteriorly over the sternocleidomastoid muscle near the mastoid process. Type II nerves (40%) left the posterior border of the sternocleidomastoid muscle and swung medially (up to 4.5cm posterior to the posterior border of the sternocleidomastoid muscle) as they ascended over the occiput. The lesser occipital nerve was near a midpoint of a line between the external occipital protuberance and mastoid process in all specimens with the type II nerve configuration. Based on our findings, the inverted U incision would be less likely to injure the type II nerves but would necessarily cross over type I nerves, especially more cranially on the nerve at the apex of the incision. As the more traditional linear incision would most likely transect the type I nerves and more so near their trunk, the U incision may be the overall better choice in avoiding neural and occipital artery injury during retrosigmoid approaches.

    Full Text Available Sarah Baker, Alysa Fairchild Department of Radiation Oncology, Cross Cancer Institute, University of Alberta, Edmonton, AB, Canada Abstract: Radiation-induced esophagitis is the most common local acute toxicity of radiotherapy (RT delivered for the curative or palliative intent treatment of lung cancer. Although concurrent chemotherapy and higher RT dose are associated with increased esophagitis risk, advancements in RT techniques as well as adherence to esophageal dosimetric constraints may reduce the incidence and severity. Mild acute esophagitis symptoms are generally self-limited, and supportive management options include analgesics, acid suppression, diet modification, treatment for candidiasis, and maintenance of adequate nutrition. Esophageal stricture is the most common late sequela from esophageal irradiation and can be addressed with endoscopic dilatation. Approaches to prevent or mitigate these toxicities are also discussed. Keywords: non–small cell lung cancer, acute, late, toxicity, stricture

    The two main histological esophageal cancer types, adenocarcinoma and squamous cell carcinoma, differ in incidence, geographic distribution, ethnic pattern and etiology. This article focuses on epidemiology with particular reference to geographic and temporal variations in incidence, along with a review of the evidence supporting environmental and genetic factors involved in esophageal carcinogenesis. Squamous cell carcinoma of the esophagus remains predominantly a disease of the developing world. In contrast, esophageal adenocarcinoma is mainly a disease of western developed societies, associated with obesity and gastro-esophageal reflux disease. There has been a dramatic increase in the incidence of adenocarcinoma in developed countries in parallel with migration of both esophageal and gastric adenocarcinomas towards the gastro-esophageal junction.

    Computed tomography (CT) was used for detecting ongoing pelvic hemorrhage in patients with pelvic fracture, and for deciding an indication or transcatheter arterial embolization. The authors compared plane CT with contrast-enhanced CT to examine the value of contrast-enhanced CT in detecting arterial injury with pelvic fracture. The diagnosis of arterial injury was made by angiography. CT-determined hematoma was detected in 10 parts according to bleeding sites. Each hematoma was counted and compared with angiographic arterial injury. Contrast-enhanced CT was more useful than plane CT, but the hemorrhage sites determined by contrast-enhanced CT were not identical with those of angiographic arterial injuries. (author)

    Antiphospholipid syndrome (APS) is a distinct autoimmune prothrombotic disorder due to pathogenic autoantibodies directed against proteins that bind to phospholipids. APS is characterized by arterial and venous thrombosis and their clinical sequelae. Catastrophic antiphospholipid syndrome (CAPS) is a rare and often fatal form of APS characterized by disseminated intravascular thrombosis and ischemic injury resulting in multiorgan failure. Rarely, intravascular thrombosis in CAPS is accompanied by hemorrhagic manifestations such as diffuse alveolar hemorrhage. Here, we report a 43-year-old woman who presented with anemia, acute gastroenteritis, abnormal liver function tests, bilateral pulmonary infiltrates, and a systemic inflammatory response syndrome. The patient developed respiratory failure as a result of diffuse alveolar hemorrhage followed by acute renal failure. Laboratory tests disclosed hematuria, proteinuria, and reduced platelet count. Microbiologic tests were negative. A renal biopsy demonstrated acute thrombotic microangiopathy and extensive interstitial hemorrhage. Serologic tests disclosed antinuclear antibodies and reduced serum complement C4 concentration. Coagulation studies revealed the lupus anticoagulant and autoantibodies against cardiolipin, beta 2-glycoprotein I, and prothrombin. High-dose glucocorticoids and plasma exchange resulted in rapid resolution of pulmonary, renal, and hematological manifestations. This rare case emphasizes that CAPS can present with concurrent thrombotic and hemorrhagic manifestations. Rapid diagnosis and treatment may result in complete recovery.

    Aortic coarctation complicated with spinal artery aneurysm rupture is exceptionally rare and can be source of intraspinal hemorrhage with markedly poor prognosis. A 21-year-old man visited the emergency department because of chest and back pain along with immobility of bilateral lower limbs immediately after he woke up in the morning. Complete flaccid paraplegia and hypoesthesia in dermatome below bilateral T3 level and pain over axial region from neck to lumbar region were noted. A computed tomography excluded aortic dissection. Magnetic resonance imaging revealed a fusiform lesion involving the anterior epidural space from C7 to T2 level suspected of epidural hemorrhage, causing compression of spinal cord. He started intravenous corticosteroid but refused operation concerning the surgical benefits. Severe chest pain occurred with newly onset right bundle branch block that developed the other day. Coronary artery angiography revealed myocardial bridge of left anterior descending coronary artery at middle third and coarctation of aorta. He underwent thoracic endovascular aortic repair uneventfully. The patient was hemodynamically stable but with slow improvement in neurologic recovery of lower limbs. Aortic coarcation can cause paralysis by ruptured vascular aneurysms with spinal hemorrhage and chest pain that mimics acute aortic dissection. A history of hypertension at young age and aortic regurgitated murmurs may serve as clues for further diagnostic studies. Cautious and prudent evaluation and cross disciplines cares are essential for diagnosis and successful management of the disease.

    2006-01-01

    Esophageal achalasia is the most commonly diagnosed primary esophageal motor disorder and the second most common functional esophageal disorder. Current therapy of achalasia is directed toward elimination of the outflow resistance caused by failure of the lower esophageal sphincter to relax completely upon swallowing. The advent of minimally invasive surgery has nearly replaced endoscopic pneumatic dilation as the first-line therapeutic approach. In this editorial, the rationale and the evidence supporting the use of laparoscopic Heller myotomy combined with fundoplication as a primary treatment of achalasia are reviewed.

    2011-12-01

    Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved.

    Full Text Available The incidence of esophageal cancer is rapidly increasing especially in developing countries. The major risk factors include unhealthy lifestyle practices such as alcohol consumption, smoking, and chewing tobacco to name a few. Diagnosis at an advanced stage and poor prognosis make esophageal cancer one of the most lethal diseases. These factors have urged further research in understanding the pathophysiology of the disease. Animal models not only aid in understanding the molecular pathogenesis of esophageal cancer but also help in developing therapeutic interventions for the disease. This review throws light on the various recent laboratory animal models for esophageal cancer.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

    Full Text Available The purpose of present study was to assess the effects of thoracic epidural anesthesia on splanchnic perfusion, bacterial translocation and histopathologic changes in experimental hemorrhagic shock in short-tailed macaques (Macaca nemestrina. Sixteen Macaca nemestrinas were randomly assigned to one of two groups i.e. the lidocaine group (n = 8, receiving general anesthesia plus lidocaine thoracic epidural anesthesia; and the saline group (n = 8, receiving general anesthesia alone as control. Hemorrhagic shock was induced by withdrawing blood gradually to a mean arterial pressure (MAP of 40 mm Hg, and maintained for 60 minutes. Animals were then resuscitated with their own blood and ringer lactate solution (RL. After resuscitation, epidural lidocaine 2% was given in the lidocaine group and saline in the control group. Resuscitation that was performed after one hour hemorrhagic shock, with hemodynamic variables and urine output returned to normal, revealed there was no improvement of splanchnic perfusion. PgCO2, P(g-aCO2, and pHi remained in critical value and tended to deteriorate in the saline group. Contrast to saline group, splanchnic perfusion in lidocaine group tended to improve. This condition was supported by the finding of less bacterial translocation and better histopathologic changes in lidocaine thoracic epidural anesthesia group than in saline group. This study concludes that lidocaine thoracic epidural anesthesia attenuates splachnic hypoperfusion in post-resuscitation hemorrhagic shock in Macaca nemestrina.

    A case of massive hemorrhage from colon of diverticular origin is reported. A complete study of operative specimen allowed precise localization of diverticulum responsible and guidance of histopathologists in their search for the arterial erosion. Histology showed loss of arterial substance with total communication with diverticular lumen. A literature review emphasized vascular relations of diverticuli and the role of stercoliths in the mechanical agression responsible for the massive hemorrhage. It also illustrated the predominance of arteriography in the modern diagnostic and therapeutic approach to these lesions.

    2015-10-09

    Pradaxa (dabigatran) is a direct thrombin inhibitor approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. We describe a case of esophageal ulceration associated with Pradaxa administration in a 75-year-old man. The patient reported difficulty swallowing and a burning sensation after taking his first dose of Pradaxa. An esophagogastroduodenoscopy (EGD) revealed linear ulcerations in the mid-esophagus. Pradaxa was held beginning the day before the EGD. The patient reported that his pain and difficulty swallowing resolved on stopping Pradaxa. Pradaxa is formulated with a tartaric acid excipient to reduce variability in absorption. We hypothesise that the capsule lodged in the patient's esophagus and the tartaric acid may have caused local damage resulting in an esophageal ulcer. It is important to educate patients on proper administration of Pradaxa, to decrease the risk of this rare, but potentially serious adverse event.

    AIM To understand the molecular mechanism of esophageal cancer development and provide molecular markers for screening high-risk populations and early diagnosis. METHODS Two-dimensional electrophoresis combined with mass spectrometry were adopted to screen differentially expressed proteins in nine cases of fetal esophageal epithelium, eight cases of esophageal cancer, and eight cases of tumor-adjacent normal esophageal epithelium collected from fetuses of different gestational age, or esophageal cancer patients from a high-risk area of esophageal cancer in China. Immunohistochemistry (avidin-biotin-horseradish peroxidase complex method) was used to detect the expression of peroxiredoxin (PRX)6 in 91 cases of esophageal cancer, tumor-adjacent normal esophageal tissue, basal cell hyperplasia, dysplasia, and carcinoma in situ, as well as 65 cases of esophageal epithelium from fetuses at a gestational age of 3-9 mo. RESULTS After peptide mass fingerprint analysis and search of protein databases, 21 differential proteins were identified; some of which represent a protein isoform. Varying degrees of expression of PRX6 protein, which was localized mainly in the cytoplasm, were detected in adult and fetal normal esophageal tissues, precancerous lesions, and esophageal cancer. With the progression of esophageal lesions, PRX6 protein expression showed a declining trend (P PRX6 protein expression showed a declining trend with age (P PRX6 protein expression was significantly higher in well-differentiated esophageal cancer tissues than in poorly differentiated esophageal cancer tissues (P PRX6 protein is associated with fetal esophageal development and cancer differentiation.

  16. Optimal lymphadenectomy for esophageal adenocarcinoma.

    Science.gov (United States)

    Oezcelik, A

    2013-08-01

    Recently published data have shown that an extended lymphadenectomy during the en bloc esophagectomy leads to a significant increased long-term survival for esophageal adenocarcinoma. On the other hand some studies indicate that the increased survival is based on stage migration and that the surgical complication rate is increased after extended lymphadenectomy. The aim of this review was to give an overview about all aspects of an extended lymphadenectomy in patients with esophageal adenocarcinoma. The review of the literature shows clearly that the number of involved lymph nodes is an independent prognostic factor in patients with esophageal adenocarcinoma. Furthermore, an extended lymphadenectomy leads to an increased long-term survival. Some studies describe that 23 lymph nodes should be removed to predict survival; other studies 18 lymph nodes or 15 lymph nodes. Opponents indicate that the survival benefit is based on stage migration. The studies with a large study population have performed a Cox regression analyzes and identified the number of lymph nodes removed as an independent factor for improved survival, which means it is significant independently from other parameters. Under these circumstances is stage migration not an option to explain the survival benefit. An important difficulty is, that there is no standardized definition of an extended lymphadenectomy, which means the localization and number of removed lymph nodes differ depending from the performing centre. The controversies regarding the survival benefit of the lymphadenectomy is based on the lack of standardisation of the lymphadenectomy. The main goal of further studies should be to generate a clear definition of an extended lymphadenectomy in patients with esophageal adenocarcinoma.

  17. Novel device to sample the esophageal microbiome--the esophageal string test.

    Directory of Open Access Journals (Sweden)

    Sophie A Fillon

    Full Text Available A growing number of studies implicate the microbiome in the pathogenesis of intestinal inflammation. Previous work has shown that adults with esophagitis related to gastroesophageal reflux disease have altered esophageal microbiota compared to those who do not have esophagitis. In these studies, sampling of the esophageal microbiome was accomplished by isolating DNA from esophageal biopsies obtained at the time of upper endoscopy. The aim of the current study was to identify the esophageal microbiome in pediatric individuals with normal esophageal mucosa using a minimally invasive, capsule-based string technology, the Enterotest™. We used the proximal segment of the Enterotest string to sample the esophagus, and term this the "Esophageal String Test" (EST. We hypothesized that the less invasive EST would capture mucosal adherent bacteria present in the esophagus in a similar fashion as mucosal biopsy. EST samples and mucosal biopsies were collected from children with no esophageal inflammation (n = 15 and their microbiome composition determined by 16S rRNA gene sequencing. Microbiota from esophageal biopsies and ESTs produced nearly identical profiles of bacterial genera and were different from the bacterial contents of samples collected from the nasal and oral cavity. We conclude that the minimally invasive EST can serve as a useful device for study of the esophageal microbiome.

    2012-01-01

    Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus.The improvement of survival observed over the previous two decades is multifactorial and largely attributable to advances in neonatal intensive care,neonatal anesthesia,ventilatory and nutritional support,antibiotics,early surgical intervention,surgical materials and techniques.Indeed,mortality is currently limited to those cases with coexisting severe life-threatening anomalies.The diagnosis of EA is most commonly made during the first 24 h of life but may occur either antenatally or may be delayed.The primary surgical correction for EA and TEF is the best option in the absence of severe malformations.There is no ideal replacement for the esophagus and the optimal surgical treatment for patients with long-gap EA is still controversial.The primary complications during the postoperative period are leak and stenosis of the anastomosis,gastro-esophageal reflux,esophageal dysmotility,fistula recurrence,respiratory disorders and deformities of the thoracic wall.Data regarding long-term outcomes and follow-ups are limited for patients following EA/TEF repair.The determination of the risk factors for the complicated evolution following EA/TEF repair may positively impact long-term prognoses.Much remains to be studied regarding this condition.This manuscript provides a literature review of the current knowledge regarding EA.

    2013-10-07

    Acute variceal hemorrhage, a life-threatening condition that requires a multidisciplinary approach for effective therapy, is defined as visible bleeding from an esophageal or gastric varix at the time of endoscopy, the presence of large esophageal varices with recent stigmata of bleeding, or fresh blood visible in the stomach with no other source of bleeding identified. Transfusion of blood products, pharmacological treatments and early endoscopic therapy are often effective; however, if primary hemostasis cannot be obtained or if uncontrollable early rebleeding occurs, transjugular intrahepatic portosystemic shunt (TIPS) is recommended as rescue treatment. The TIPS represents a major advance in the treatment of complications of portal hypertension. Acute variceal hemorrhage that is poorly controlled with endoscopic therapy is generally well controlled with TIPS, which has a 90% to 100% success rate. However, TIPS is associated with a mortality of 30% to 50% in such a setting. Emergency TIPS should be considered early in patients with refractory variceal bleeding once medical treatment and endoscopic sclerotherapy failure, before the clinical condition worsens. Furthermore, admission to specialized centers is mandatory in such a setting and regional protocols are essential to be organized effectively. This review article discusses initial management and then focuses on the specific role of TIPS as a primary therapy to control acute variceal hemorrhage, particularly as a rescue therapy following failure of endoscopic approaches.

    The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

    Full Text Available Objective To evaluate the value of color Doppler flow imaging (CDFI and pulsed-wave Doppler (PWD in monitoring renal hemodynamics in rabbits with acute hemorrhagic shock. Methods The experimental model of acute hemorrhagic shock was reproduced in 16 normal New Zealand white rabbits by controlled exsanguination which was divided into 4 different grades: normal (100% MAP, mild (70% MAP, moderate (50% MAP, and severe (40% MAP. The right kidney of the experimental animal was examined by gray-scale ultrasound (2DUS, CDFI and PWD. The structure of the right kidney was observed with 2DUS. CDFI was used to monitor the change in right renal hemodynamics along with the progression of shock. The hemodynamic parameters of main renal artery (MRA, segmental renal artery (SRA and interlobar renal artery (IRA were measured by PWD, including the peak systolic velocity (Vmax, minimum diastolic velocity (Vmin and resistive index (RI. Results The animal model of hemorrhagic shock was successfully reproduced in 16 healthy New Zealand rabbits, of which 14 rabbits survived at the end of the experiment, and 2 died of severe shock. The mean arterial pressure (MAP declined, while the respiratory rate and heart rate increased as the circulation changed from normal to severe shock (P<0.05. Observation of the right renal structure by 2DUS revealed no obvious changes after bleeding in different degrees. CDFI showed a gradually reduced distribution of blood flow in renal hemodynamics along with the progression of hemorrhagic shock. Vmax and Vmin declined gradually, while RI intensity increased as the hemorrhagic shock progressed from minor to severe. There was statistically significant difference in RI intensity between different grades of shock (P<005. Conclusion CDFI and PWD can quantitatively assess the renal hemodynamics during acute hemorrhagic shock, so it can be used as a noninvasive monitoring tool in the diagnosis and treatment of hemorrhagic shock.

    Postpartum hemorrhage (PPH) is a potentially life threatening condition, and it remains the leading cause of maternal morbidity. Uterine atony, lower genital tract lacerations, uterine rupture or inversion, retained products of conception and underlying coagulopathy are some of the common causes of PPH. Most conditions can be diagnosed based on clinical and laboratory evaluation supplemented by ultrasound information. Computed tomography (CT) or magnetic resonance (MR) imaging can provide information for the detection, localization and characterization of PPH in some difficult cases. CT can accurately demonstrate the anatomic location of significant arterial hemorrhage as sites of intravenous contrast material extravasation, which can be as a guide for angiographic intervention. The presence of focal or diffuse intravenous contrast extravasation or a hematoma within the enlarged postpartum uterine cavity on CT can help the diagnosis of uterine atony when the clinical diagnosis of uterine atony is unclear. CT can also provide the information of other alternative conditions such as a puerperal genital hematoma, uterine rupture and concealed hematoma in other sites. MR imaging may be considered as a valuable complement to ultrasound where the ultrasound findings are inconclusive in the diagnosis and differential diagnosis of retained products of conception. Knowledge of the various radiologic appearances of PPH and the correlation with clinical information can ensure correct diagnosis and appropriate and prompt treatment planning in the patients with PPH.

    Candida esophagitis (moniliasis) is the most common infection of the gullet and has generally been attributed to as a complication of immune suppressed state. However, as the current case. Holt found the disease to occur in 3 of his 13 patients without predisposing condition. Predisposing factors other than immune deficient conditions include aplastic anemia, alcoholism and Parkinson's disease and age, diabetes mellitus, and disruption of mucosal integrity. Growing prevalence of Candida esophagitis in recent years is accounted for by an increase in the number of patients with organ transplantation, malignancy and AIDS as well as populrization of endoscopy. Microorganisms that reached the esophagus in oral secretions are rarely cultured from the esophageal surface. Of many species C. albicans is the most common offender although C. tropicalis has also been isolated with high prevalence, particularly in the patients with cancer and disseminated candidiasis. Clinically, the patients with Candida esophagitis seek medical care for esophageal or retrosternal pain, dysphagia or distress. Candida esophagitis may be the extension from oropharyngeal infection but in the majority the esophagus is the sole site of infection. The middle and lower thirds of the esophagus are more typically affected than the upper third. Diagnosis can be indicated by double contrast esophagography or endoscopy and confirmed by potassium hydroxide (KOH) stain or biopsy. It is to be noted that the more presence of Candida in smear or cultured specimen cannot indict Candida as definitive offender. Differential diagnosis includes herpes simplex infection, cytomegalovirus infection, reflux esophagitis or radiation esophagitis.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophagealmotility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from nonerosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

    The natural history of chronic radiation esophagitis occurring in previously normal esophagus is still unknown. The authors describe here the long-term outcome of chronic esophagitis arising after neck irradiation for oropharynx and larynx carcinomas in 13 consecutive adult patients. The first clinical signs of radiation esophagitis were dysphagia or impossibility of oral intake, which appeared within 26 months (range 2--120 months) after the end of radiation for pyriform fossae carcinoma (N = 5), tonsil carcinoma (N = 2), larynx carcinoma (N = 2), pharynx carcinoma (N = 2), base of the tongue (N = 1), and thyroid carcinomas (N = 1). During upper endoscopy, an esophageal stenosis was found in 11 cases and was associated with ulceration in three cases. An isolated esophageal ulceration was present in only two cases. Chronic radiation esophagitis diagnosis was confirmed by histology and surgery in seven cases. In the last six cases, diagnosis was supported by the absence of first cancer relapses within a median follow-up of two years (16 months to nine years) and by endoscopic findings. Seven patients received parenteral or enteral nutrition. Ten patients were treated by peroral dilatations. These treatments allowed nearly normal oral diet in 11/13 patients. Only one patient was lost of follow-up after 20 months. Four patients died from chronic radiation esophagitis. One of these patients died from massive hemorrhage after peroral dilatation. Four patients died of a second carcinoma with no first cancer recurrence. Four patients were alive after six months to nine years of follow-up. Moderate dysphagia was still present, allowing nearly normal oral feeding. In conclusion, chronic radiation esophagitis is a severe disease with an underestimated frequency. In this study, peroral dilatations appeared to be necessary and were not associated with an increased morbidity. 21 refs., 1 tab.

    Gastroesophageal reflux disease (GERD) and esophageal achalasia are common benign esophageal diseases. Today minimally invasive surgery is recommended to treat these diseases. Surgical indications for GERD are failure of medical management, medical complications attributable to a large hiatal hernia, 'atypical' symptoms (asthma, hoarseness, cough, chest pain, aspiration), etc. according to the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) guidelines. Laparoscopic Nissen fundoplication has emerged as the most widely accepted procedure for GERD patients with normal esophageal motility. Partial fundoplication (e.g., Toupet fundoplication) is also considered to decrease the possibility of postoperative dysphagia. Although pneumatic dilatation has been the first line treatment for esophageal achalasia, laparoscopic Heller myotomy and partial fundoplication (e.g., Dor fundoplication) to prevent reflux is preferred by most gastroenterologists and surgeons as the primary treatment modality. Laparoscopic surgery for GERD and esophageal achalasia are effective in most patients and safe in all patients. Finally, laparoscopic surgery should be performed only by skilled surgeons.

    Lichen planus is an uncommon inflammatory mucocutaneous disorder affecting the skin and its appendages, as well as oral and genital mucosa. Involvement of the esophageal mucosa is rare and causes significant morbidity, with dysphagia and risk of long-term complications, such as esophageal strictures and stenosis. Esophageal lichen planus is an underreported condition in the spectrum of lichenoid tissue reactions, presenting the risk of systemic manifestations. We describe a patient with severe, long-standing esophageal lichen planus, which had led to marked weight-loss, malnutrition syndrome and chronic respiratory distress due to recurrent aspiration pneumonia. Diagnosis was confirmed by the presence of concomitant muco-cutaneous lesions and characteristic endoscopic and histological findings. Systemic therapy with cyclosporine A and micronutrient supplementation led to rapid clinical improvement. Early diagnosis of esophageal lichen planus as well as effective systemic immunosuppressive treatment is crucial in order to prevent short- and long-term complications.

    Esophageal stricture is a rare complication of paediatric cancer treatment that usually occurs after esophageal exposure to radiotherapy. We describe 4 cases of esophageal stricture during chemotherapy for acute lymphoblastic leukemia. All patients presented with refractory vomiting and were diagnosed with radiologic contrast studies. None of the patients had received radiotherapy. Esophageal candidiasis was seen in 2 patients but the remaining 2 patients had earlier systemic candidiasis. High-dose dexamethasone may predispose these children to both esophageal candidiasis and peptic esophagitis. The etiology of esophageal strictures during treatment for acute leukemia is likely to be multifactorial but systemic candidiasis may play a significant role.

    Lichen planus (LP) affects mucocutaneous surfaces and is characterized by intraepithelial and lamina propria lymphocytosis and squamous cell apoptosis (Civatte bodies). Lichen planus esophagitis (LPE) is underrecognized; concurrent cutaneous disease is present in some patients, but LPE alone is more common. We diagnose patients with characteristic pathologic findings of LPE and known correlation with skin disease or immunofluorescence (IF) results as LPE but use descriptive terminology ("lichenoid esophagitis pattern" [LEP]) when confirmation is unavailable. We reviewed clinicopathologic features of patients diagnosed at our institution with LPE or LEP. There were 88 specimens with LPE or LEP from 65 patients. Most patients were female. Seventeen patients had LPE confirmed by IF. Five patients had both esophageal (1 with IF) and skin LP. Strictures were a prominent presenting feature in LPE patients, with disease distribution more frequent in the upper and lower esophagus. Dysphagia was a common reason for endoscopy in LEP patients. Rheumatologic diseases are more common in patients with LPE compared with LEP. Viral hepatitides and human immunodeficiency virus (HIV) infections are associated with LEP. We defined polypharmacy as patients taking >3 medications; this finding was present in both LPE and LEP cohorts; however, this is a prominent feature in those with established LPE. Progression to dysplasia was noted in both cohorts. About 5% of LPE patients have tandem skin manifestations. LPE is more likely than LEP to arise in women, result in stricture formation, and be associated with rheumatologic disorders and polypharmacy, whereas LEP is associated with viral hepatitis and HIV. Both can progress to neoplasia. As the risk of stricture formation is high in patients with LPE, it is worth performing pertinent IF studies to confirm LPE, although knowledge of the clinical association of LEP with viral hepatitis, HIV, and use of multiple medications is of value in

    Despite significant advancements in the understanding of the pathophysiological mechanisms of subarachnoid hemorrhage (SAH), little is known about the emotional consequences. The primary goal of this study was to describe the locomotor and behavioral patterns in rats following both a single-injection and double-injection model of SAH. In 48 rats, SAH was induced by injecting 0.3 ml of autologous arterial blood into the cisterna magnum (single-hemorrhagic model). In 24 of these rats, post-SAH vasospasm was induced by a repeated injection of blood into the cisterna magnum 24h later (double-hemorrhagic model). In 24 additional rats, 0.3 ml of saline was injected into the cisterna magnum (sham group). Neurological performance was assessed at 24, 48 h, 1, 2 and 3 weeks after SAH. Four behavioral tests were performed for 3 weeks after SAH for the duration of 6 consequent days, in the following order: open field test, sucrose preference test, elevated plus maze test and forced swimming test. Following both, a single and double-hemorrhagic models of SAH, rats were found to have significant behavioral abnormalities on the open field test, sucrose preference test, elevated plus maze test, and forced swimming test. A more prominent disability was found in rats that underwent the double-hemorrhagic model of SAH than rats that underwent the single-hemorrhagic model. Both a single and double injection model of rats SAH are associated with significant behavioral disturbances including locomotor abnormalities, depressive behavior and increased anxiety, even as early as 3 weeks after SAH.

    Mid-esophageal diverticula are rare entities. Only symptomatic patients usually receive surgical treatment. Esophageal leakage is one of the most common complications after these procedures. Though in literature, operative management is the preferred treatment for esophageal fistula, conservative approach is described in case of small leaks. We report a case of an operated giant mid-esophageal diverticulum complicated with an esophageal fistula. The patient underwent a surgical treatment and recovered completely.

    有后续妊娠。结论 PAE用于治疗原发性产后出血的疗效确切,安全微创,有助于保留患者的生育功能。%Objective To evaluate the efficacy and safety of pelvic arterial embolization (PAE) in women with intractable primary postpartum hemorrhage (PPH). Methods Clinical data of 36 cases were analyzed retrospectively in which women underwent PAE for intractable primary PPH in Peking Union Medical College Hospital between Jan 2006 and Jan 2015. The success rate of PAE were measured and possible predictive risk factors associated with treatment failure were analyzed. The complications secondary to PAE were also recorded. Results (1)The etiology of PPH. Among the 36 cases, 21 patients delivered viginally (Group VD) and 15 received cesarean section (Group CS). The most frequent cause of PPH was uterine atony (72%, 26/36). The less common causes were placental problems (28%, 10/36), genital tract trauma (6%, 2/36) and coagulation defects (3%, 1/36) in turn. Three patients (8%, 3/36) had combined causes.(2)Interventions before PAE. Uterotonic medications were used in all patients. 31 patients received carboprost methylate suppositorites,27 received carbetocin and 31 received carboprost tromethamine. Besides, 20 patients received one or more surgical interventions before PAE. PAE was performed when these interventions failed. (3) Characteristics of PAE. Altogether 78 arteries were embolized in 36 cases. Embolization of bilateral uterine arteries was performed in 31 cases, right internal iliac artery and bilateral inferior epigastric arteries were embolized in one case. Right internal pudendal artery, bilateral uterine arteries and bilateral internal iliac arteries were embolized in one case. And bilateral uterine arteries, bilateral internal iliac arteries were embolized in one case. In the other 2 cases, bilateral internal iliac arteries were embolized.(4)Efficacy of PAE. The overall technical success rate of PAE was 100%(36/36), while the clinical success rate was 94

    Full Text Available Aortoesophageal fistulas are a rare but commonly fatal complication of esophageal cancer. Reports of successfully managed cases are few, with high mortality and morbidity usually resulting from failure to control the initial massive haemodynamic insult. We report the case of a 47-year-old Caucasian man with recently diagnosed advanced esophageal cancer who suffered an episode of massive haematemesis. Emergency gastroscopy revealed an arterial bleeding point in the proximal esophagus. A self-expanding metal esophageal stent was placed to achieve initial partial haemostasis. CT angiography confirmed an aortoesophageal fistula. An endoluminal stent device was thus inserted within the thoracic aorta stabilising the bleeding point. The patient subsequently made an uneventful recovery and was discharged on long-term antibiotics for palliative care. He survived for 2 months at home before dying of disseminated malignancy. The successful use of esophageal stenting as a means of achieving haemostasis, allowing time for endovascular intervention, is as yet a relatively unexplored area of management of this rare condition.

    Spontaneous non-traumatic intracerebral hemorrhage (ICH) is associated with high morbidity and mortality throughout the world with no proven effective treatment. Majority of hematoma expansion occur within 4 h after symptom onset and is associated with early deterioration and poor clinical outcome. There is a vital role of ultra-early hemostatic therapy in ICH to limit hematoma expansion. Patients at risk for hematoma expansion are with underlying hemostatic abnormalities. Treatment strategy should include appropriate intervention based on the history of use of antithrombotic use or an underlying coagulopathy in patients with ICH. For antiplatelet-associated ICH, recommendation is to discontinue antiplatelet agent and transfuse platelets to those who will undergo neurosurgical procedure with moderate quality of evidence. For vitamin K antagonist-associated ICH, administration of 3-factor or 4-factor prothrombin complex concentrates (PCCs) rather than fresh frozen plasma to patients with INR >1.4 is strongly recommended. For patients with novel oral anticoagulant-associated ICH, administering activated charcoal to those who present within 2 h of ingestion is recommended. Idarucizumab, a humanized monoclonal antibody fragment against dabigatran (direct thrombin inhibitor) is approved by FDA for emergency situations. Administer activated PCC (50 U/kg) or 4-factor PCC (50 U/kg) to patients with ICH associated with direct thrombin inhibitors (DTI) if idarucizumab is not available or if the hemorrhage is associated with a DTI other than dabigatran. For factor Xa inhibitor-associated ICH, administration of 4-factor PCC or aPCC is preferred over recombinant FVIIa because of the lower risk of adverse thrombotic events. PMID:28360881

  4. Activity assessment of eosinophilic esophagitis.

    2014-01-01

    The activity of eosinophilic esophagitis (EoE) can be assessed with patient-reported outcomes and biologic measures. Patient-reported outcomes include symptoms and quality of life, whereas biologic measures refer to endoscopic, histologic, and biochemical activity (e.g. blood biomarkers). So far, a validated tool to assess EoE activity in the above-mentioned dimensions is lacking. Given the lack of a standardized way to assess EoE activity in the various dimensions, the results of different clinical trials may be difficult to compare. For symptom assessment in adult patients, the symptom 'dysphagia' should be evaluated according to different standardized food consistencies. Furthermore, symptom assessment should take into account the following items: avoidance of specific food categories, food modification, and time to eat a regular meal. A distinct symptom recall period (e.g. 2 weeks) has to be defined for symptom assessment. Performing an 'esophageal stress test' with ingestion of a standardized meal to measure symptom severity bears the potential risk of acute food bolus impaction and should therefore be avoided. The description of endoscopic findings in EoE has meanwhile been standardized. Histologic evaluation of EoE activity should report either the size of the high-power field used or count the eosinophils per mm(2). There is a current lack of blood biomarkers demonstrating a good correlation with histologic activity in esophageal biopsies. The development and validation of an adult and pediatric EoE activity index is urgently needed not only for clinical trials and observational studies, but also for daily practice.

  5. Endoscopic mucosectomy: an alternative treatment for superficial esophageal cancer.

    Science.gov (United States)

    Lambert, R

    2000-01-01

    Recent trends in the management of superficial esophageal cancer consist of improved detection, pretherapeutic staging and reliable criteria for curative endoscopic therapy. The endoscopic treatment is legitimate when the cancer is at an early stage, intra-epithelial or microinvasive (m1 or m2) and N0. Submucosal cancer should not be treated with a curative intent by endotherapy. Concerning squamous cell cancer, the oriental and occidental pathologists include high-grade dysplasia in the same group as intramucosal cancer. The distinction is however maintained for adenocarcinoma in the Barrett's esophagus. Indications of endoscopic rather than surgical treatment rely on: (1) the small size of the tumor (not more than 2 cm in diameter); (2) the endoscopic morphology in the type 0 of the Japanese classification with the flat subtypes IIa and IIb rather than type IIc--there is high risk of submucosal invasion for the polypoid (type I) or ulcerated superficial cancer (type III); and (3) the endoscopic ultrasound staging, with confirmed integrity of the hyperechoic submucosal layer. The high-frequency (20 MHz) miniprobe is preferred to the standard (7.5 MHz) instrument. The elective procedure for tumor eradication is endoscopic mucosectomy. The technique is associated with a 6.8% risk of severe complications (hemorrhage or perforation) and a recurrence rate of 3%-7%. The 5-year survival rate is similar to that of surgery (over 80%). In the small group of patients with superficial esophageal cancer (less than 10% of the disease) endoscopic treatment may now be proposed in about 30% of cases, surgery is preferred for submucosal cancer and for neoplasia with a large surface. Areas of high-grade dysplasia in the Barrett's esophagus offer a new and increasing sector of indications. The concurrent endoscopic procedure of destruction--photodynamic therapy--is preferred for the destruction of lesions with poorly delineated limits.

    This study was conducted to evaluate the clinical profile and outcome in late hemorrhagic disease of the newborn (HDN) with particular reference to intracranial hemorrhage. Infants (n = 42) presenting with late HDN from January 1998 to December 2001 were studied. Majority (76%) were in the age group of 1-3 months. All were term babies on exclusive breast-feeding and none received vitamin K at birth. 71% patients presented with intracranial hemorrhage, commonest site being intracerebral and multiple ICH. Visible external bleeding was noted in 1/3rd of patients only. Three patients expired. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Isolated intracranial hemorrhage is a common mode of presentation.

    2015-01-01

    Full Text Available Uncontrolled arterial bleeding during laparoscopic cholecystectomy is a serious problem and may increase the risk of bile duct damage. Therefore, accurate identification of the anatomy of the cystic artery is very important. Cystic artery is notoriously known to have a highly variable branching pattern. We reviewed the anatomy of the cystic artery and its branch to cystic duct as seen through the video laparoscope. A single artery to cystic duct with the classical “H-configuration” was demonstrated in 161 (91.47% patients. This branch may cause troublesome bleeding during laparoscopic dissection in the hepatobiliary triangle. Careful identification of artery to cystic duct is helpful in the proper dissection of Calot’s triangle as it reduces the chances of hemorrhage and thus may also be helpful in prevention of extrahepatic biliary radical injuries.

    Dense and extensive esophageal strictures after caustic agent ingestion require surgical treatment. Colon, stomach and jejunum can be used to reconstruct esophagus. Here, we report an unusual patient with corrosive esophageal stricture who had received unsuccessful esophageal replacements twice at other hospitals. Colon interposition had been first performed 6 months after corrosive esophageal burn,but the colon graft necrosis occurred. Esophageal reconstruction had been carried out 10 years later in another hospital. However, the graft necrosis developed again 5 months later. A salvage operation was performed to remove the necrotic transplant in our hospital. Then as much food as possible had been given to expand the stomach through the gastrostomy since the procedure. The patient underwent esophagectomy and concomitant gastroesophagostomy in the neck 1.5 years later. Esophageal dilations had been performed to prevent recurrent anastomotic stricture for 1 year. He has eaten a normal diet since being discharged.

    In a series of 500 patients admitted to hospital for upper digestive hemorrhage, the authors studied the influence of taking drugs on the clinical characteristics and course of the original disease. Taking aspirin is exceptional before rupture of esophageal varices. One may isolate a homogenous group of elderly women consuming aspirin and another anti-inflammatory drug, and bleeding from a gastric ulcer. One may also isolate another group of men, bleeding from acute gastro-duodenal lesions after taking aspirin alone. If one considers apart portal hypertension, owing to its extreme gravity, one may note that the prognosis depends on the age. One patient out of five, dies of hemorrhage after the age of 60 years. Taking an anti-inflammatory drug at this age is thus not harmless.

    2010-01-01

    @@ Massive presacral venous hemorrhage is a non-pulsatile hemorrhage due to the rupture of either the presacral venous plexus or the sacral vertebral basivertebral vein. It is a serious complication of surgery for pelvic tumors, like middle or low segment rectal cancers, advanced ovarian cancers and presacral tumors. Massive presacral venous hemorrhage is dangerous and difficult to manage. Traditional methods for controlling this condition include packing with laparotomy pads, the use of sterile thumbtacks,1 ligation of the internal iliac vessel,2 and selective arterial embolization.3 These methods are generally ineffective. Recently, several other methods for controlling presacral bleeding have been reported, such as occlusion of the wound with rectus muscle fragment welding,4 oppression with sterile normal saline bags,5 balloon tamponade,6 and the use of endoscopic staples.7 However, these measures fail to arrest the bleeding in some patients, resulting in massive hemorrhage and even death.

    The aim of this study is to evaluate the feasibility of Laser Doppler imaging (LDI) for noninvasive and dynamic assessment of hemorrhagic shock in a rabbit model. A rabbit model of hemorrhagic shock was generated and LDI of the microcirculation in the rabbit ears was performed before and at 0, 30, 60, and 90 min after hemorrhage. The CCD (Charge Coupled Device) image of the ears, the mean arterial pressure (MAP) and the heart rate (HR) were monitored. The mean LDI flux was calculated. The HR of rabbits was significantly (p 0.05). Both the flux numbers and the red-to-blue color changes on LDI imaging showed the reduction of the microcirculation. LDI imaging is a noninvasive and non-contact approach to evaluate the microcirculation and may offer benefits in the diagnosis and treatment of hemorrhage shock. Further studies are needed to confirm its effectiveness in clinical practice.

    Esophageal and gastric cancers are both common and deadly. Patients present most often after disease progression and survival is therefore poor. Due to demographic variability and recent changes in disease incidence, much emphasis has been placed on studying risk factors for both esophageal and gastric cancers.However, with increasing understanding of these diseases, low survival rates persist and continued intensive studies are necessary to optimize treatment plans. This review article discusses updates in the evolving epidemiology, clinical presentation, risk factors,and diagnostic and treatment modalities of esophageal and gastric cancers.

    Fifty consecutive patients with different esophageal symtoms were investigated with esophageal endoscopy, transit scintigraphy, and gastroesophageal (GE) scintigraphy with extra-abdominal compression. Scintigraphic findings were abnormal in 27 of those 31 patients (87%) who were classified as abnormal at endoscopy. A prolonged transit time was the commonest finding, but hiatal hernia and GE reflux were also found. However, the scintigraphic procedure showed abnormalities in 6 of 19 (31%) patients who were classified as normal at endoscopy. Esophageal scintigraphy is recommended as a screening test before endoscopy is decided on. 20 refs.

    2011-01-01

    Viral hemorrhagic fevers (VHFs) caused by arenaviruses belong to the most devastating emerging human diseases and represent serious public health problems. Arenavirus VHFs in humans are acute diseases characterized by fever and, in severe cases, different degrees of hemorrhages associated with a shock syndrome in the terminal stage. Over the past years, much has been learned about the pathogenesis of arenaviruses at the cellular level, in particular their ability to subvert the host cell's innate antiviral defenses. Clinical studies and novel animal models have provided important new information about the interaction of hemorrhagic arenaviruses with the host's adaptive immune system, in particular virus-induced immunosuppression, and have provided the first hints towards an understanding of the terminal hemorrhagic shock syndrome. The scope of this article is to review our current knowledge on arenavirus VHF pathogenesis with an emphasis on recent developments.

    Laparoscopic surgery for esophageal achalasia was first reported by Shimi et al. in 1991. Subsequently the procedure has been performed all over the world and laparoscopic Heller myotomy and Dor fundoplication (Heller and Dor operation) is now thought to be the operation of first choice. It is indicated for patients who are resistant to medical therapy (calcium blocker etc.) or have pneumatic dilatation and those with frequent aspiration at night. As Csendes et al. reported that surgical treatment was better than pneumatic dilatation and as laparoscopic surgery is less invasive, the indications for the laparoscopic Heller and Dor operation can include all achalasia patients except those who respond to medical therapy, do not accept surgery, or cannot tolerate surgery. We successfully performed the laparoscopic Heller and Dor operation on 22 patients, all of whom had an uneventful postoperative course. Manometric evaluation, endoscopic examination, and 24-hour pH monitoring showed good results. There are six important technical points: 1) flexible laparoscopy; 2) pneumoperitoneum; 3) gauze in the abdominal cavity to absorb blood; 4) laparosonic coagulating shears; 5) extracorporeal knot-tying technique; and 6) intracorporeal knot-tying technique. If an experienced surgeon is in charge, the laparoscopic Heller and Dor operation is an ideal, minimally invasive treatment for esophageal achalasia.

    To investigate cyclooxygenase- 2(Cox-2) protein expression in esophageal cancer and precancerous lesions. Methods: One hundred twenty biopsy specimens from esophageal carcinoma and 113 from patients with esophageal premalingnant lesions, 27 from individuals with normal esophageal mucosa and 3 from Barrett's esophagus were examined for Cox-2 protein expression by immunohistochemistry. Results: Cox-2 protein was not observed in normal esophageal squamous and glandular epithelium, hyperplasia from mild to severe dysplasia lesions and carcinoma in situ. Positive Cox-2 protein expression was found in 4 of 60 specimens of invasive squamous-cell carcinomas, 21 of 30 specimens of esophageal adenocarcinomas and in 3 of 3 Barret's esophageal tissues. Conclusion: The Cox-2 protein expression may be associated with the development of the esophageal adenocarcinomas but not esophageal squamous-cell carcinomas.

    Full Text Available Blister aneurysms of are rare lesions representing a real challenge for diagnosis and management. They typically show small size, hemispherical shape, fragile wall, broad neck, and are arising from non-branching sites of intracranial arteries. Materials and Methods: We retrospectively reviewed all aneurysms treated at our institution. Seventeen patients (6 male, 11 female with 17 blister aneurysms were identified (mean age 53.3, range 41-63 years. Clinical, procedural, angiographic data as well as follow up data were evaluated. Results: All patients presented with aneurysmal subarachnoid hemorrhage. Majority of the blister aneurysms were located in ICA while 1 was located at posterior cerebral artery, 1 at vertebral and 1 involving basilar artery. All patients were treated using single or overlapping stents and if possible additional coiling. There was no intra-operative rupture. Good outcome (mrs 0-2 was seen in 14 patients. Poor clinical outcome (mrs 3-5 was seen in 2 patients due to vasospasm induced ischemic deficits at discharge, both of them improved on follow up (mrs 1 on follow up. There were 3 mortalities, One patient died of rebleeding while other 2 died due to SAH induced complications. Follow-up angiography was available in 16 patients (one patient died before follow up angiogram and revealed complete or near complete aneurysm occlusion in 11, incomplete obliteration in 1 and no change in 2 cases. Two cases showed post-treatment angiographic aneurysm recurrence. Both cases were managed with repeat coiling and overlapping stent placement. Conclusion: Endovascular management using single/overlapping stent and if possible coil placement is technically safe and feasible in blister aneurysms. Overlapping stents lead to better aneurysm occlusion than a single stent. Blister aneurysm in dorso-medial ICA showed higher tendency of continued growth/recurrence, higher incidence of clinical vasospasm and in these cases early angiographic follow

    Thalamoperforating artery aneurysms are rarely reported in the literature. We report an extremely rare case of ruptured distal anterior thalamoperforating artery aneurysm which was treated by endovascular obliteration in a patient with occlusion of both the internal carotid arteries (ICAs) : A 72-year-old woman presented with severe headache and loss of consciousness. Initial level of consciousness at the time of admission was drowsy and the Glasgow Coma Scale score was 14. Brain computed tomography (CT) scan was performed which revealed intracerebral hemorrhage in right basal ganglia, subarachnoid hemorrhage, and intraventricular hemorrhage. The location of the aneurysm was identified as within the globus pallidus on CT angiogram. Conventional cerebral angiogram demonstrated occlusion of both the ICAs just distal to the fetal type of posterior communicating artery and the aneurysm was arising from right anterior thalamoperforating artery (ATPA). A microcatheter was navigated into ATPA and the ATPA proximal to aneurysm was embolized with 20% glue. Post-procedural ICA angiogram demonstrated no contrast filling of the aneurysm sac. The patient was discharged without any neurologic deficit. Endovascular treatment of ATPA aneurysm is probably a more feasible and safe treatment modality than surgical clipping because of the deep seated location of aneurysm and the possibility of brain retraction injury during surgical operation.

    Background Esophageal variceal bleeding is a frequent and severe complication in patients with cirrhosis. The aim of this study was to identify prognostic factors of esophageal variceal rebleeding in cirrhotic inpatients.Methods Consecutive cirrhotic patients who were admitted to Changhai Hospital because of esophageal variceal bleeding were retrospectively analyzed. To assess the independent factors for recurrent hemorrhage after esophageal variceal bleeding, medical assessment was completed at the time of their initial hospital admission, including documentation of clinical, biochemical, and treatment methods that might contribute to variceal rebleeding. Univariate and multivariate analyses were retrospectively performed.Results Totally 186 patients (35.8%) were assigned to a rebleeding group and the other 334 patients (64.2%) to a non-rebleeding group. Multivariate stepwise regression analysis showed that four variables were positively correlated with rebleeding: Child-pugh grade B (OR=2.664, 95% CI 1.680-4.223) (compared with Child-pugh grade A), total bilirubin (Tbil) (OR=1.0006, 95% CI 1.002-1.0107), creatinine (OR=1.008, 95% CI 1.002-1.015) and the cumulative volume of blood transfusion (OR=1.519, 95% CI 1.345-1.716). The presence of ascites (OR=0.270, 95% CI 0.136-0.536) and prophylactic antibiotics (OR=0.504, 95% CI 0.325-0.780) were negatively correlated with rebleeding of the cirrhotic inpatients. According to standardized coefficient, the importance of rebleeding predictors ranked from the most to the least was as follows: the cumulative volume of blood transfusion, Child-pugh grade B, Tbil and creatinine.Conclusion Rebleeding in cirrhotic inpatients was associated with more blood transfusions, Child-pugh grade B, higher Tbil and creatinine.

    Full Text Available Vasospasm remains an extremely serious complication that affects patients presenting with subarachnoid hemorrhage (SAH due to ruptured intracranial aneurysms. The current therapeutic armamentarium is still insufficient in many cases, and the search for new therapies is necessary. In this study, we evaluated the effect of N-acetylcysteine (NAC on cerebral arterial vasospasm using an experimental model. Twenty-four wistar rats were divided into 4 groups: [1] Control, [2] SAH, [3] SAH+NAC and [4] SAH+Placebo. The experimental model employed double subarachnoid injections of autologous blood. The proposed dose of NAC was 250 mg/kg intraperitoneally per day. We analyzed the inner area of the basilar artery to assess the action of NAC. The experimental model proved to be very adequate, with a mortality rate of 4%. The inner area of the basilar artery in the SAH group showed significant difference to the control group (p=0.009. The use of NAC significantly reduced vasospasm as compared to the untreated group (p=0.048 and established no significant difference to the control group (p=0.098. There was no significant improvement with the administration of placebo (p=0.97. The model of the dual hemorrhage proved to be very useful for vasospasm simulation, with overall low mortality. The administration of NAC significantly reduced vasospasm resulting from SAH, and may represent a new therapeutic alternative.

    Background and Purpose The location of intracerebral hemorrhage (ICH) is currently described in a qualitative way; we provide a quantitative framework for estimating ICH engagement and its relevance to stroke outcomes. Methods We analyzed 111 patients with ICH from the MISTIE II clinical trial. We estimated ICH engagement at a population level using image registration of CT scans to a template and a previously labeled atlas. Predictive regions of NIHSS and GCS stroke severity scores, collected at enrollment, were estimated. Results The percent coverage of the ICH by these regions strongly outperformed the reader-labeled locations. The adjusted R2 almost doubled from 0.129 (reader-labeled model) to 0.254 (quantitative-location model) for NIHSS and more than tripled from 0.069 (reader-labeled model) to 0.214 (quantitative-location model). A permutation test confirmed that the new predictive regions are more predictive than chance: p<.001 for NIHSS and p<.01 for GCS. Conclusions Objective measures of ICH location and engagement using advanced CT imaging processing provide finer, objective, and more quantitative anatomic information than that provided by human readers.

    2016-01-01

    Systemic sclerosis is a rare connective tissue disease, distinctive features of which are fibrosis and microangiopathy. The esophagus is one of the most commonly involved internal organs. Most patients experience dysphagia, difficulties in swallowing and gastro-esophageal reflux. However, in up to one third of cases, the initial onset of esophageal disease may be clinically silent. There are several diagnostic modalities available for assessing both morphological and functional abnormalities of the esophagus. If structural abnormalities are suspected, endoscopy is the method of choice. Functional evaluation is best achieved with manometry. Both endoscopy and manometry are invasive techniques, with low patient acceptance. Barium-contrast study is well tolerated, but qualitative assessment of functional abnormalities is imprecise. Esophageal scintigraphy is an easy, non-invasive, sensitive and specific diagnostic modality. It can detect esophageal dysfunction even in asymptomatic patients. In patients already diagnosed with systemic sclerosis, scintigraphy is useful in evaluating severity and progression of the disease.

    Esophageal schwannomas are a relative rare benign neoplasm that usually occurs in the upper esophagus, in the middle aged women. We report a case of a 67-year-old man with a lower esophageal schwannoma. This lesion was composed of homogenous density, iso-attenuating with the chest wall muscle on pre- and post-contrast chest computed tomography (CT). The CT findings of the esophageal schwannoma are similar to those of esophageal leiomyoma. Hense, esophageal schwannoma may be a differential diagnosis with esophageal leiomyoma.

    Objective: To examine the expressions of MDM2, P53 and P27 proteins in chronic esophagitis, para-cancer mucosa and esophageal carcinoma. Methods: Immunohistochemistry was used to detect the expressions of MDM2, P53 and P27 proteins in forty-seven patients suffering from chronic esophagitis and eighty-five cases of esophageal carcinoma and corresponding para-cancer mucosa. Flow cytometry((FCM) was applied to detect the quantities of these proteins expressed in fresh tissues of 48 cases of esophageal cancer and their para-cancer tissues and 24 cases of relative normal mucosa at the surface of cutting edge. Results: Immunohistochemistry results showed that the expressions of the three studied proteins were very similar in the epithelia of chronic esophagitis and para-cancer mucosa (P>0.05). Both the qualitative and quantitative studies displayed that the P53 protein had no expression and its accumulations would appear only in the early stages of esophagus canceration while the MDM2 and P27 proteins had different degrees of expressions in cases of normal esophageal mucosa. MDM2 protein markedly increased in the advanced stages of esophageal canceration. A quantitative study showed that the expression of P27 protein had a linearity of decreasing tendency (F=9.132,P=0.002) in the course of esophageal canceration. Conclusion: Chronic esophagitis may be a precancerous lesion. Owing to the changes of the P53 and P27 proteins, we can also conclude that these occur in the early stages of esophagus oncogenesis, however the changes of MDM2 expression may occur in the advanced stage of esophageal canceration.

    AIM: To explore the dynamic changes in the pressure of the lateral ventricle during acute brainstem hemorrhage and the changes of neural discharge of vagus nerve under the load of intracranial hypertension, so as to analyze their effects on the congestive degree of intestinal mucous membrane and the morphologic changes of intestinal mucous membrane. METHODS: An operation was made to open the skull to obtain an acute brainstem hemorrhage animal model. Microcirculatory microscope photography device and video recording system were used to determine the changes continuously in the caliber of jejunal mesenteric artery during brainstem hemorrhage and the changes with time in the congestion of jejunal mucosal villi. We used HE stain morphology to analyze the changes of duodenal mucosal villi. A recording electrode was used to calculate and measure the electric discharge activities of cervical vagus nerve. RESULTS: (1) We observed that the pressure of lateral cerebral ventricle increased transiently during acute brainstem hemorrhage; (2) The caliber of the jejunal mesenteric artery increased during brainstem hemorrhage. Analysis of red color coordinate values indicated transient increase in the congestion of jejunal mucous membrane during acute brainstem hemorrhage; (3) Through the analysis of the pathologic slice, we found enlarged blood vessels, stagnant blood, and transudatory red blood cells in the duodenal submucous layer; (4) Electric discharge of vagus nerve increased and sporadic hemorrhage spots occurred in duodenal mucous and submucous layer, when the lateral ventricle was under pressure. CONCLUSION: Brainstem hemorrhage could cause intracranial hypertension, which would increase the neural discharge of vagus nerve and cause the transient congestion of jejunal mucous membrane. It could cause hyperemia and diffused hemorrhage in the duodenal submucous layer 48 h after brainstem hemorrhage. PMID:15786536

    AIM: To assess the prevalence of laryngopharyngeal reflux (LPR) in patients with reflux esophagitis and dis-close factors contributing to the development of LPR.METHODS: A total of 167 patients who proved to have reflux esophagitis by endoscopy were enrolled.ings for the diagnosis of LPR. We used validated ques-tionnaires to identify the presence of laryngopharyn-geal symptoms, and stringent criteria of inclusion to increase the specificity of laryngoscopic findings. The data of patients were analyzed statistically to find out factors related to LPR.RESULTS: The prevalence rate of LPR in studied sub-jects with reflux esophagitis was 23.9%. Age, hoarse-ness and hiatus hernia were factors significantly as-sociated with LPR. In 23 patients with a hiatus hernia,the group with LPR was found to have a lower trend of esophagitis grading.CONCLUSION: Laryngopharyngeal reflux is present in patients with reflux esophagitis, and three predicting factors were identified. However, the development of LPR might be different from that of reflux esophagi-tis. The importance of hiatus hernia deserves further study.

    Downhill esophageal varices are a rare cause of upper gastrointestinal hemorrhage. We present a case of downhill variceal bleeding due to superior vena cava thrombosis resulting from a prior central venous catheter. The patient was managed with endoscopic band ligation and later with surgical axillary vein to right atrium bypass grafting. Successful long-term resolution of varices was achieved at 1 year of follow-up. This is the longest follow-up described for combined endoscopic and surgical management in the existing literature for catheter-associated downhill varices. PMID:27807564

    Full Text Available Background. Although relaxin causes vasodilatation in systemic arteries, little is known about its role in cerebral arteries. We investigated the expression and role of relaxin in basilar arteries after subarachnoid hemorrhage (SAH in rabbits. Methods. Microarray analysis with rabbit basilar artery RNA was performed. Messenger RNA expression of relaxin-1 and relaxin/insulin-like family peptide receptor 1 (RXFP1 was investigated with quantitative RT-PCR. RXFP1 expression in the basilar artery was investigated with immunohistochemistry. Relaxin concentrations in cerebrospinal fluid (CSF and serum were investigated with an enzyme-linked immunosorbent assay. Using human brain vascular smooth muscle cells (HBVSMC preincubated with relaxin, myosin light chain phosphorylation (MLC was investigated with immunoblotting after endothelin-1 stimulation. Results. After SAH, RXFP1 mRNA and protein were significantly downregulated on day 3, whereas relaxin-1 mRNA was significantly upregulated on day 7. The relaxin concentration in CSF was significantly elevated on days 5 and 7. Pretreatment with relaxin reduced sustained MLC phosphorylation induced by endothelin-1 in HBVSMC. Conclusion. Upregulation of relaxin and downregulation of RXFP1 after SAH may participate in development of cerebral vasospasm. Downregulation of RXFP1 may induce a functional decrease in relaxin activity during vasospasm. Understanding the role of relaxin may provide further insight into the mechanisms of cerebral vasospasm.

    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); of which late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. Children with cholestatic liver disease are at risk for developing secondary vitamin K deficiency because of fat malabsorbtion and inadequate dietary intake. In this study, we described 11 infants with cholestatic liver disease with different etiologies exhibiting intracranial hemorrhage (ICH). Six patients underwent surgical evacuation of ICH, following the administration of vitamin K and/or fresh frozen plasma. The possibility of cholestatic liver disease should be considered in the treatment of ICH due to vitamin K deficiency.

    We performed a retrospective analysis of non-contrast computed tomography (CT) scans, immediately subsequent magnetic resonance imaging (MRI), and cerebral angiography data from 30 consecutive patients with acute ischemic stroke within 6 hours after symptom onset. Results showed that eleven patients developed subsequent hemorrhagic transformation at follow-up. A hyperintense middle cerebral artery sign on MRI was found in six hemorrhagic patients, all of who had acute thrombosis formation on magnetic resonance angiography and digital subtraction angiography. No patients in the non-hemorrhagic group had hyperintense middle cerebral artery sign on MRI. The sensitivity, specificity, and positive predictive values of the hyperintense middle cerebral artery sign on MRI T1-weighted image for subsequent hemorrhagic transformation were 54.5%, 100%, and 100% respectively. Hyperdense middle cerebral artery sign on non-contrast CT was observed in nine patients, five of who developed hemorrhagic transformation. These data suggest that hyperintense middle cerebral artery sign on MRI T1-weighted image is a highly specific and moderately sensitive indicator of subsequent hemorrhagic transformation in patients after acute ischemic stroke, and its specificity is superior to CT.

    AIM: To analyze the clinical and dosimetric predictive factors for radiation-induced esophageal injury in patients with non-small-cell lung cancer (NSCLC) during threedimensional conformal radiotherapy (3D-CRT). METHODS: We retrospectively analyzed 208 consecutive patients (146 men and 62 women) with NSCLC treated with 3D-CRT. The median age of the patients was 64 years (range 35-87 years). The clinical and treatment parameters including gender, age, performance status, sequential chemotherapy, concurrent chemotherapy, presence of carinal or subcarinal lymph nodes, pretreatment weight loss, mean dose to the entire esophagus, maximal point dose to the esophagus, and percentage of volume of esophagus receiving >55 Gy were studied. Clinical and dosimetric factors for radiation-induced acute and late grade 3-5 esophageal injury were analyzed according to Radiation Therapy Oncology Group (RTOG) criteria.RESULTS: Twenty-five (12%) of the two hundred and eight patients developed acute or late grade 3-5 esophageal injury. Among them, nine patients had both acute and late grade 3-5 esophageal injury, two died of late esophageal perforation. Concurrent chemotherapy and maximal point dose to the esophagus ≥60 Gy were significantly associated with the risk of grade 3-5 esophageal injury. Fifty-four (26%) of the two hundred and eight patients received concurrent chemotherapy. Among them, 25 (46%) developed grade 3-5 esophageal injury (P = 0.0001<0.01). However, nograde 3-5 esophageal injury occurred in patients who received a maximal point dose to the esophagus <60 Gy (P= 0.0001<0.01).CONCLUSION: Concurrent chemotherapy and the maximal esophageal point dose ≥60 Gy are significantly associated with the risk of grade 3-5 esophageal injury in patients with NSCLC treated with 3D-CRT.

    Objective. To investigate clidcally useful markers for determining the severity of hemorrhagic shock and adequacy of resuscitation. Methods. Prospective study was undertaken in 12 dogs, using an established model for hemorrhagic shock. The anesthetized dogs were bled to s mean arterial pressure of 40 mmHg which was maintained for 3 hours. Then each animal was resuscitated with heperinized whole blood followed by intravenous infusion of dobutamine at a rate of 5 μg·kg-1·min-1 for 10 minutes. Arterial and mixed venous blood gases, arterial lactate concentrations and bemndynamic parameters were measured throughout the study. Results. A difference in the PCO2 and pH values between arterial and mixed venous blond was observed. Arterlal-venous PCO2 and pH difference increased signifmantly after sustained shock. The arterioveraxts carbon dioxide and pH gradients recovered more rapidly than arterial lactate levels after successful resuscitation with blond and dobutamine. Conclusion. Arterial blood gases fail to reflect the acld-base status of tissues during hemorrhagic shock,The differences in PCO2 and pH vslues between arterial and mixed venous blood could he used as clinical indicators for assessing the severity of shock and efficacy of resuscitation.

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

    Goal-directed fluid therapy optimizes cardiac output and flap perfusion during anesthesia. Intraoperative esophageal Doppler (ED) monitoring has been reported as more accurate and reliable, demonstrating improved surgical outcomes compared with central venous pressure and arterial catheter monitoring. A prospective study of patients undergoing free perforator (deep inferior epigastric artery perforator/anterolateral thigh) flap surgery with intraoperative ED monitoring (51 patients) or central venous pressure monitoring (53 patients) was undertaken. Fluid input included crystalloids, colloids, or blood products. Fluid output included urine, blood, or suctioned fluid. Postoperative fluid balance was calculated as fluid input - output. Fluid input between groups was not different. Fluid output was greater in the ED group (P = 0.008). The ED group showed less fluid balance (P = 0.023), less anesthetic time (P = 0.001), less hospital stay (mean 1.9 days; P = 0.147), less monitoring and flap complications (P = 0.062). ED monitoring demonstrated no monitoring complications, provides a favorable postoperative fluid balance, and may reduce flap complications and hospital stay.

    Vascular cognitive impairment and vascular dementia are composed of cognitive deficits resulted from a range of vascular lesions and pathologies, including both ischemic and hemorrhagic. However the contribution of spontaneous intracerebral hemorrhage presumed due to small vessel diseases on cognitive impairment is underestimated, in contrast to the numerous studies about the role of ischemic vascular disorders on cognition. In this review we summarize recent findings from clinical studies and appropriate basic science research to better elucidate the role and possible mechanisms of intracerebral hemorrhage in cognitive impairment and dementia. This article is part of a Special Issue entitled: Vascular Contributions to Cognitive Impairment and Dementia edited by M. Paul Murphy, Roderick A. Corriveau and Donna M. Wilcock.

  13. A histopathologic study of retinal arterial aneurysms.

    Fichte, C; Streeten, B W; Friedman, A H

    1978-04-01

    An isolated retinal arterial aneurysm was found postmortem in the eye of a 75-year-old hypertensive woman, and multiple aneurysms were in the enucleated eye of a 68-year-old hypertensive man with neovascular glaucoma. The aneurysmal sites showed thickening of the vessel walls with hyaline, fibrin, and foamy macrophages. Fresh or organized thrombus partially filled the aneurysmal lumina. Trypsin digestion preparations in Case 2 showed a progressive severity of aneurysmal changes from the simplest "cuff" type to the hemorrhagic "b;pwout" aneurysms with a linear split in the vessel wall. Atheroma was present in the larger arterial branches and fat was in most of the aneurysmal walls. These findings suggested that damage to the arterial wall by cholesterol or other emboli, or by occlusive disease, may predispose especially hypertensive patients to arterial aneurysm formation.

    A variety of diseases involve the esophagus including esophagitis, benign or malignant tumors, varices, and esophageal perforation. We reviewed the thoracic CT of these various esophageal diseases, and classified them by similar CT findings. The CT findings were circumferential wall thickening, nodular wall thickening, abnormal luminal dilatation, fistula formation, and mass or mass like lesion. Although CT alone has limited diagnostic ability in esophageal disease, it may have an important role in diagnosing submucosal dissection, fistula, perforation, and intramural abscess.

    After successful renal artery angioplasty and stent placement, a patient in a fully anticoagulated state developed hypotension and flank pain. Computed tomography (CT) of the abdomen revealed a large renal subcapsular haematoma which was successfully managed conservatively without embolotherapy and surgical intervention. To prevent hemorrhage after renal artery stenting, it is necessary to underscore the importance of reducing the contrast volume and pressure of angiography, controlling systemic blood pressure, and monitoring guide wire position at all times.

    The article presents an overview of the current clinical application of clopidogrel in coronary artery surgery. The viewpoint is that clopidogrel can reduce preoperative and postoperative ischemic events of coronary artery bypass grafting(CABG). With the development of standardized medication and the corresponding preventive technique, it will be of great value to reduce hemorrhage complications and obtain the maximum benefit from clopidogrel' s anti-platelet properties.

    To assess the efficacy and safety of arterial embolotherapy in patients with massive duodenal hemorrhage. Between January 1999 and June 2002, 25 patients (age: 34-81, mean 58, male: 19, female: 6) underwent arterial embolization for duodenal hemorrhage after failed endoscopic therapy. The hemorrhage originated from duodenal ulcer in sixteen patients, from cancer with duodenal invasion in five patients, from endoscopic sphincterectomy in two patients, and from pseudoaneurysm complicating acute pancreatitis in two patients. Hemorrhage was detected at endoscopy and an attempt was made to treat it endoscopically in all patients, but failed in each case. At angiography, direct bleeding signs such as contrast extravasation or pseudoaneurysm were demonstrated in nineteen patients. In the six patients without angiographic evidence of bleeding, blind embolization of the gastroduodenal artery was performed based on the endoscopic examination. Microcoil and gelfoam particles were used as embolic agents. Hemostasis was achieved immediately after embolotherapy in 21 patients (84%). Bleeding recurred in 4 patients (16%), and of these cases, one was successfully treated purely by endoscopic means, a second was reembolized three times due to bleeding from the collateral vessels of the tumor and the two others were treated by surgery. After the procedure, six patients died (24%). The causes of death were disseminated intravascular coagulopathy, multiorgan failure, sepsis and acute renal failure. The underlying diseases of the deceased patients were cancers with duodenal invasion (n=4) and abdominal aortic aneurysm with ischemic colitis (n=1). Transarterial embolotherapy in the case of massive duodenal hemorrhage is a safe and effective procedure. Even in the absence of angiographic evidence of bleeding, blind embolization of the gastroduodenal artery is effective for patients in the surgically high risk group.

    Sheehan's syndrome is described as panhypopituitarism secondary to a pituitary hypoperfusion during or just after obstetric hemorrhage. Advances in obstetric care make this syndrome quite unusual, but some cases are reported in underdeveloped countries. Clinical presentation may change depending on the severity of the hormone deficiencies. The diagnosis is clinical, but abnormalities are observed in the magnetic resonance in up to 70% of patients. We present a case of a woman with hypotension, hypothermia and edemas in relation to a previous massive postpartum hemorrhage. Failure in lactation was the clue to the diagnosis. A review of its main features, its diagnosis and treatment in the current literature is also presented.

    Hemorrhage in regions remote from the site of initial intracranial operations is rare, but does occur. We report three cases of cerebellar hemorrhage that developed after supratentorial surgery, all of which had similar clinical findings and CT images. The first case was a 37-year-old man with a craniopharyngioma in the suprasellar lesion. Partial removal of the tumor was performed through frontal craniotomy and the translaminaterminals approach. A large quantity of cerebospinal fluid (CSF) was suctioned from the third ventricle during the operation, resulting in marked brain shrinkage. The second and third cases were 34- and 51-year-old women with unruptured right middle cerebral aneurysms. Clipping of the aneurysms through the pterional approach was performed in both cases. In the second case, CSF was suctioned in large quantity from the carotid and prechiasmal cistern at the operation, resulting in marked brain shrinkage. In the third case, however, only a small volume of CSF was suctioned from the carotid and prechiasmal cistern during the operation, and no marked brain shrinkage was observed. CT scan showed that the hematomas were located mainly in the subdural or the subarachnoid spaces over the cerebellar hemisphere and partially extending into the cerebellar cortex. The mechanism of cerebellar hemorrhage in these series of patients was thought to be multifactorial. The possible etiology for cerebellar hemorrhage in the three cases presented was examined, including the role of CSF suction during surgery and disturbance of venous circulation in the posterior fossa. Suction of the CSF may cause intracranial hypotension. Further reduction of intracranial pressure leads to an increased transluminal venous pressure. There was no episode of hypertension or disturbed blood coagulation during or after the operation. The preoperative angiogram also revealed no abnormality at the region of the posterior fossa.

    We report a case of a 39-year-old man who presented with a nonfunctioning pituitary macroadenoma which extended into the suprasellar region. He underwent a transcranial resection of the tumor followed eight months later by transsphenoidal surgery for the residual tumor. Postoperatively he developed massive subarachnoid and intraventricular hemorrhage. A cerebral angiogram revealed a leaking anterior communicating artery aneurysm which was not seen on the computed tomography angiography and magnetic resonance angiography before the surgery. Complications of transsphenoidal surgery, particularly vascular hemorrhagic complications, and risk of rupture of undetected aneurysms are discussed.

    Full Text Available The surgical treatment of intracranial aneurysms by clipping is recognized as effective and definitive. However some cases that suffered a new subarachnoid hemorrhage (SAH some time after they were submitted to aneurysm clipping have raised doubts about the concept of "cure"after this treatment. Eleven patients previously submitted to aneurysm clipping who presented a new SAH were analyzed. The time elapsed from surgery to SAH varied from 3 to 10 years. After SAH four patients had a poor outcome. The new episode of SAH occurred due to intrinsic factors of the cerebral vasculature: 1. a weak point of the vessel wall near the previous aneurysm, 2. a weak point of another vessel far from the previous aneurysm, 3. a previous infundibular dilation of the posterior communicating artery; and due to technical problems: 1. aneurysm not identified during the previous treatment, 2. aneurysm deliberately left untreated, 3. persistence of the aneurysm due to inappropriate surgery, 4. persistency of part of the aneurysm neck after clipping and 5. slipping of the clip from the neck of the aneurysm. The measures to prevent new SAH after surgery start with adequate preoperative angiographic studies, a careful inspection of the position of the clip and emptying of the aneurysm. Early angiography studies may reveal a persistent neck and later ones may reveal newly developed aneurysms. In conclusion, SAH after aneurysm clipping is a late and severe phenomenon and the concept of "cure" after this surgery should be interpreted with caution.O tratamento cirúrgico dos aneurismas cerebrais através de sua clipagem é reconhecido como eficaz e definitivo.

    The authors compared the cardiovascular and hormonal responses to angiotensin converting enzyme inhibition and hemorrhage of 20% of blood volume in chronically instrumented unanesthetized newborn lambs and adult sheep. Administration of the nonsulfhydryl-containing converting-enzyme inhibitor enalapril reduced mean arterial pressure in the newborn but not in the adult animals. Blood pressure fell in both age groups after hemorrhage, and the hemorrhage-induced fall in blood pressure, integrated over the period of hypovolemia, was more pronounced when converting-enzyme inhibition was present in the lambs. This was not observed in the adults. Cardiac output fell following hemorrhage in both age groups, and the fall was greater when enalapril was present in the lambs, but this was not the case in the adults. Hemorrhage increased plasma renin activity in both groups, and enalapril augmented this increase. Plasma concentrations of vasopressin, measured by radioimmunoassay, and catecholamines measured by radio enzymatic assay, increased following hemorrhage within and between groups. Taken together these data suggest that the renin-angiotensin systems plays a more important role in the maintenance of cardiovascular homeostasis in newborn lambs than it does in adult sheep, and catecholamine and vasopressin responses to volume loss can occur in the presence of blockade of the renin-angiotensin system.

    Patients with esophageal cancer have a poor prognosis because they often have no symptoms until their disease is advanced.There are no screening recommendations for patients unless they have Barrett's esophagitis or a significant family history of this disease.Often,esophageal cancer is not diagnosed until patients present with dysphagia,odynophagia,anemia or weight loss.When symptoms occur,the stage is often stage Ⅲ or greater.Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection.The treatment of patients who have locally advanced esophageal cancer is more complex and controversial.Despite multiple trials,treatment recommendations are still unclear due to conflicting data.Sadly,much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically.Additionally,studies have been underpowered or stopped early due to poor accrual.In the United States,concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient.Patients who have metastatic disease are treated palliatively.The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer,and to review the literature which guides our treatment recommendations.

    The widespread popularity of new surgical technologiessuch as laparoscopy, thoracoscopy and robotics has ledmany surgeons to treat esophageal diseases with thesemethods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperativecomplications, length of hospital stay, and pain andbetter cosmetic results. All of these benefits couldpotentially be of great interest when dealing with theesophagus due to the potentially severe complicationsthat can occur after conventional surgery. Moreover,robotic platforms are expected to reduce many of thedifficulties encountered during advanced laparoscopicand thoracoscopic procedures such as anastomoticreconstructions,accurate lymphadenectomies, andvascular sutures. Almost all esophageal diseases areapproachable in a minimally invasive way, includingdiverticula, gastro-esophageal reflux disease, achalasia,perforations and cancer. Nevertheless, while the limitsof MIS for benign esophageal diseases are mainlytechnical issues and costs, oncologic outcomes remainthe cornerstone of any procedure to cure malignancies,for which the long-term results are critical. Furthermore,many of the minimally invasive esophageal operationsshould be compared to pharmacologic interventionsand advanced pure endoscopic procedures; such acomparison requires a difficult literature analysis andleads to some confounding results of clinical trials. Thisreview aims to examine the evidence for the use of MISin both malignancies and more common benign diseaseof the esophagus, with a particular emphasis on futuredevelopments and ongoing areas of research.

  18. Self-Expandable Metal Stents for Persisting Esophageal Variceal Bleeding after Band Ligation or Injection-Therapy: A Retrospective Study.

    Martin Müller

    Full Text Available Despite a pronounced reduction of lethality rates due to upper gastrointestinal bleeding, esophageal variceal bleeding remains a challenge for the endoscopist and still accounts for a mortality rate of up to 40% within the first 6 weeks. A relevant proportion of patients with esophageal variceal bleeding remains refractory to standard therapy, thus making a call for additional tools to achieve hemostasis. Self-expandable metal stents (SEMS incorporate such a tool.We evaluated a total number of 582 patients admitted to our endoscopy unit with the diagnosis "gastrointestinal bleeding" according to our documentation software between 2011 and 2014. 82 patients suffered from esophageal variceal bleeding, out of which 11 cases were refractory to standard therapy leading to SEMS application. Patients with esophageal malignancy, fistula, or stricture and a non-esophageal variceal bleeding source were excluded from the analysis. A retrospective analysis reporting a series of clinically relevant parameters in combination with bleeding control rates and adverse events was performed.The initial bleeding control rate after SEMS application was 100%. Despite this success, we observed a 27% mortality rate within the first 42 days. All of these patients died due to non-directly hemorrhage-associated reasons. The majority of patients exhibited an extensive demand of medical care with prolonged hospital stay. Common complications were hepatic decompensation, pulmonary infection and decline of renal function. Interestingly, we found in 7 out of 11 patients (63.6% stent dislocation at time of control endoscopy 24 h after hemostasis or at time of stent removal. The presence of hiatal hernia did not affect obviously stent dislocation rates. Refractory patients had significantly longer hospitalization times compared to non-refractory patients.Self-expandable metal stents for esophageal variceal bleeding seem to be safe and efficient after failed standard therapy

    Sometimes in the course of care in a neonatal intensive care unit, there may be a rush to intervene in cases where limited intervention is actually the correct course. One such example is that of neonatal adrenal hemorrhage. We present the case of a male term neonate with shock, metabolic acidosis, distended abdomen, and falling hematocrit. His prenatal and delivery histories were uneventful except for a nuchal cord. Apgar scores were 9 and 9. Because of his dramatic presentation, certain members of the medical team suggested immediate surgical intervention. However, a calm and careful evaluation revealed the true diagnosis and course of action. Ultrasound of the abdomen showed a mass between the liver and kidney, but the origin was difficult to identify. A computed tomography scan supported the diagnosis of right adrenal hemorrhage. His serum cortisol level was normal. The patient was managed conservatively and discharged home after a 1-week stay in the hospital. Subsequent abdominal ultrasound showed resolving adrenal hemorrhage with minimal calcification. A review of the pertinent literature is presented. Physicians should remember adrenal hemorrhage when evaluating a newborn infant with shock, acidosis, abdominal distention, and falling hematocrit and that conservative management is usually indicated.

    Adult unilateral moyamoya disease with intracranial aneurysm is frequently reported in the literature, but there is much variation in its treatment. In this case report, we describe the time course and treatment regimen of a patient with moyamoya disease and review the literature regarding moyamoya disease with intracranial aneurysm. A 64-year-old man had untreated intracranial aneurysm and unilateral moyamoya disease for 10 years. He presented with sudden-onset right hemiparesis and aphasia due to a subcortical hemorrhage. He was admitted to the local neurosurgical unit, and upon resolution of symptoms, he was admitted to our hospital. A cerebral angiogram revealed the champagne bottleneck sign of the left carotid artery and obliteration of the top of the left intracranial carotid artery with a moyamoya phenomenon. Two unruptured intracranial aneurysms were identified in the anterior communicating artery(Acom A) and the right intracranial carotid artery(C3). We performed superficial temporal artery-middle cerebral artery anastomosis followed by aneurysmal neck clipping of the Acom A aneurysm. Postoperative imaging showed no new ischemic damage and improved cerebral blood flow. Although the patient experienced temporal worsening of aphasia, his function recovered a few months later and he was able to resume his normal daily life activities. The combination of direct bypass surgery and aneurysmal neck clipping might be a therapeutic option for hemorrhagic unilateral moyamoya disease with unruptured intracranial aneurysm.

    Turner syndrome (TS) is a relatively common chromosomal disorder and is associated with a range of comorbidities involving the cardiovascular system. Vascular abnormalities, in particular, are a common finding in cases of TS. However, dissection involving the vertebral arteries is rare. Here, we report the case of a 9-year-old girl with TS who had been treated with growth hormone replacement therapy for the past 3 years. She presented with weakness of both lower legs, and was ultimately diagnosed with spinal hemorrhage due to vascular malformation. We treated her with intravenous high dose dexamethasone (0.6 mg/kg) and she could walk without assistance after 6 days of treatment. In conclusion, when a patient with TS shows sudden weakness of the lower limbs, we should consider the possibility of spinal vessel rupture and try to take spine magnetic resonance imaging as soon as possible. We suggest a direction how to make a proper diagnosis and management of sudden vertebral artery hemorrhage in patients with TS.

    Full Text Available Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate secondary injury. Deep knowledge of the injuries which are directly involved alterations of glucose, offers insight as cytotoxicity, neuronal death and metabolic dysregulations alter the prognosis of patients with spontaneous intracerebral hemorrhage.

    There have been some breakthroughs in the diagnosis and treatment of esophageal achalasia in the past few years.First,the introduction of high-resolution manometry with pressure topography plotting as a new diagnostic tool has made it possible to classify achalasia into three subtyPes.The most favorable outcome is predicted for patients receiving treatment for type Ⅱ achalasia (achalasia with compression).Patients with type I (classic achalasia) and type Ⅲ achalasia (spastic achalasia) experience a less favorable outcome.Second,the first multicenter randomized controlled trial published by the European Achalasia Trial group reported 2-year follow-up results indicating that laparoscopic Heller myotomy was not superior to endoscopic pneumatic dilation (PD).Although the follow-up period was not long enough to reach a convincing conclusion,it merits the continued use of PD as a generally available technique in gastroenterology.Third,the novel endoscopic technique peroral endoscopic myotomy is a promising option for treating achalasia,but it requires increased experience and cautious evaluation.Despite all this good news,the bottom line is a real breakthrough from the basic studies to identify the actual cause of achalasia that may impede treatment success is still anticipated.

    Because the conflicting data currently available from the performed randomized trials it is very difficult to provide strict guidelines for the treatment of patients with locoregional advanced esophageal cancers. Surgery however, remains the standard of care for potentially resectable disease. Preoperative chemotherapy is still controversial with two large randomized trials resulting in two different conclusions regarding the survival benefit. Preoperative chemoradiation is also controversial since only one randomized trial showed a clear survival benefit however, the patients treated with surgery alone in this trial had an unusually poor outcome. And the study by Urba et al was not powered enough to show a clear survival benefit for patients treated with neoadjuvant chemoradiation. The results of three metaanalysis of these randomized studies show lower rate of resection, higher rate of R0-resection, more often postoperative mortality and better prognosis for patients with neoadjuvant radiochemotherapy. As a consequence one may consider offering neoadjuvant chemotherapy or neoadjuvant radiochemotherapy to patients with locallyadvanced disease under the premise that patients have a good performance status and understand the controversies about this therapeutic option. Larger trials with sufficient power to clearly detect survival benefits for patients treated with neoadjuvant chemotherapy or radiochemotherapy are necessary before this therapeutic option will be the standard of care.

    Full Text Available Background: Self-expanding metallic stents are the devices of choice in the treatment of malign or benign strictures of esophagus. Stent migration is a well-known complication of this procedure. Aims: We report a case of intestinal obstruction caused by esophageal stent migration, in which surgical intervention was used. Methods: A 65-year-old woman, who had a medical history of gastric cancer operation and esophageal stent application admitted to our emergeny department with a 48-hour history of abdominal pain, nausea and vomiting. An emergeny laparotomy was performed and the migrated stent leading to intestinal obstruction was removed. Results: The patient recovered without incident and was discharged on postoperative day 3. Conclusion: This case illustrates that esophageal stent migration has to be considered as a potential life-threatening complication.

    Esophageal cancer represents a major public health problem worldwide. Several minimally invasive esophagectomy (MIE) techniques have been described and represent a safe alternative for the surgical management of esophageal cancer in selected centers with high volume and expertise in them. This article reviews the most recent and largest series evaluating MIE techniques. Recent larger series have shown MIE to be equivalent in postoperative morbidity and mortality rates to conventional surgery. MIE has been associated with less blood loss, less postoperative pain, and decreased intensive care unit and hospital length of stay compared with conventional surgery. Despite limited data, conventional surgery and MIE have shown no significant difference in survival, stage for stage. The myriad of MIE techniques complicates the debate of defining the optimal surgical approach for treating esophageal cancer. Randomized controlled trials comparing MIE with conventional open esophagectomy are needed to clarify the ideal procedure with the lowest postoperative morbidity, best quality of life after surgery, and long-term survival.

    Full Text Available Esophagitis caused by herpes simplex virus (HSV is often documented during periods of immunosuppression in patients infected with human immunodeficiency virus (HIV; it is rare in immunocompetent diagnosed patients. Case reports of herpetic esophagitis in students of health sciences are extremely rare. The disease presents with a clinical picture characterized by acute odynophagia and retrosternal pain without obvious causes and ulcers, evidenced endoscopically in the middistal esophagus. Diagnosis depends on endoscopy, biopsies for pathology studies, and immunohistochemistry techniques. The disease course is often benign; however, treatment with acyclovir speeds the disappearance of symptoms and limits the severity of infection. In this report, we present a case of herpetic esophagitis in an immunocompetent medical student, with reference to its clinical features, diagnosis, and treatment. The disease may have manifested as a result of emotional stress experienced by the patient.

    Anti-neutrophil cytoplasmic antibody-associated vasculitis and Goodpasture's glomerular basement membrane disease are the most common causes of diffuse alveolar hemorrhage, a life-threatening disease. Systemic lupus erythematosus and the antiphospholipid syndrome are also causes of alveolar hemorrhage. We retrospectively reviewed 15 cases of diffuse alveolar hemorrhage (DAH) associated with renal diseases. Diagnosis of DAH was based on the presence of bloody bronchoalveolar lavage fluid. There were three men and 12 women, with a mean age of 50.5 years (extremes: 24-74 years). Proteinuria and hematuria were observed, respectively, in 15 and 14 cases. Six patients revealed arterial hypertension. Crescentic glomerulonephritis was diagnosed with kidney biopsies in ten cases. The etiology of renal disease was microscopic polyangiitis (MPA) in seven cases, Wegener disease in four cases, systemic lupus erythematous in one case, cryoglobulinemia in one case, myeloma in one case and propyl-thiouracil-induced MPA in one case. Hemoptysis occurred in 14 cases. The mean serum level of hemoglobin was 7.1 g/dL (5.1-10 g/dL). The mean serum creatinine concentration was 7.07 mg/dL (2.4-13.7 mg/dL). Gas exchange was severely compromised, with an oxygenation index <80 mmHg in 14 patients and <60 mmHg in seven patients. Bronchoalveolar lavage was performed in 11 cases, and had positive findings for hemorrhage in all. Methylprednisolone pulses and cyclophosphamide were used in 14 patients. Plasmapheresis was performed in three cases. One patient received cycles of Dexamethasome-Melphalan. Three patients died as a result of DAH. The mortality rate in our study was 20%.

    Full Text Available Clinically relevant animal models capable of simulating traumatic hemorrhagic shock are needed. We developed a hemorrhagic shock model with male New Zealand rabbits (2200-2800 g, 60-70 days old that simulates the pre-hospital and acute care of a penetrating trauma victim in an urban scenario using current resuscitation strategies. A laparotomy was performed to reproduce tissue trauma and an aortic injury was created using a standardized single puncture to the left side of the infrarenal aorta to induce hemorrhagic shock similar to a penetrating mechanism. A 15-min interval was used to simulate the arrival of pre-hospital care. Fluid resuscitation was then applied using two regimens: normotensive resuscitation to achieve baseline mean arterial blood pressure (MAP, 10 animals and hypotensive resuscitation at 60% of baseline MAP (10 animals. Another 10 animals were sham operated. The total time of the experiment was 85 min, reproducing scene, transport and emergency room times. Intra-abdominal blood loss was significantly greater in animals that underwent normotensive resuscitation compared to hypotensive resuscitation (17.1 ± 2.0 vs 8.0 ± 1.5 mL/kg. Antithrombin levels decreased significantly in normotensive resuscitated animals compared to baseline (102 ± 2.0 vs 59 ± 4.1%, sham (95 ± 2.8 vs 59 ± 4.1%, and hypotensive resuscitated animals (98 ± 7.8 vs 59 ± 4.1%. Evidence of re-bleeding was also noted in the normotensive resuscitation group. A hypotensive resuscitation regimen resulted in decreased blood loss in a clinically relevant small animal model capable of reproducing hemorrhagic shock caused by a penetrating mechanism.

    Squamous papilloma of the esophagus is a rare benignlesion of the esophagus. Radiofrequency ablation is anestablished endoscopic technique for the eradication ofBarrett esophagus. No cases of endoscopic ablation ofesophageal papilloma by radiofrequency ablation (RFA)have been reported. We report a case of esophagealpapilloma successfully treated with a single sessionof radiofrequency ablation. Endoscopic ablation ofthe lesion was achieved by radiofrequency using anew catheter inserted through the working channelof endoscope. The esophageal ablated tissue wasremoved by a specifically designed cup. Completeablation was confirmed at 3 mo by endoscopy withbiopsies. This case supports feasibility and safety of asa new potential indication for BarrxTM RFA in patientswith esophageal papilloma.

    In Plummer-Vinson syndrome, esophagography often reveals a web at the anterior wall of the cervical esophagus. The pathogenesis of the esophageal web and the cause of dysphagia in this syndrome were investigated radiographically, endoscopically, manometrically, and histologically. It was considered that the web seen in the esophagogram may have been formed due to the restriction of dilation of the esophageal wall, which results from repetitive inflammation and the subsequent healing process. Dysphagia in this syndrome may be explained by a decrease in swallowing power. Iron deficiency anemia may play the main role in the above histological changes and the resulting decrease in swallowing power.

  18. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    1998-01-01

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    Deficiency of vitamin K predisposes to early, classic or late hemorrhagic disease of the newborn (HDN); late HDN may be associated with serious and life-threatening intracranial hemorrhage. Late HDN is characterized by intracranial bleeding in infants aged 1 week to 6 months due to severe vitamin K deficiency, occurring particularly in exclusively breastfed infants. Late HDN is still an important cause of mortality and morbidity in developing countries where vitamin K prophylaxis is not routinely practiced. In this study, we report on two siblings with intracranial bleeding who were fully breastfed without a routine supplementation of vitamin K. Vitamin K should be given to all newborns as a single, intramuscular dose of 1 mg.

    Background Little attention has been paid to the expression of heat shock protein 27 (HSP27) in patients with reflux esophagitis (RE), and few studies of the importance of HSP27 in esophagitis have been carried out in animal models.This study aimed to explore the expression of HSP27 in the esophageal tissue of rats with RE. Methods Eighty female Wistar rats were randomly divided into experimental groups A and B and control groups C and D (n=20 in each group). To establish RE, rats in the two experimental groups received pylorus and forestomach ligations,while rats in the control group received gastrostomy and gastric perforation repair. The rats in groups A and C were sacrificed 7 days after surgery, and the rats in groups B and D were sacrificed 14 days after surgery. In groups A and B,10 and 8 rats were diagnosed with RE by pathological examination, respectively (they were included in groups A' and B',respectively). The histopathological diagnosis of all the lower esophageal tissues in groups C and D was normal and 20normal specimens were randomly selected for groups C and D' with 10 specimens in each group. Macroscopic and microscopic esophagitis scores were assessed for the specimens in groups A' and B'. Lower esophageal tissues were collected from groups A', B', C, and D', and paraffin-embedded slices were made using part of the tissues. The expression of HSP27 in the tissues was detected using the two-step streptavidin-peroxidase immunohistochemical method. Some collected tissues were frozen, and expressions of HSP27 mRNA were detected using fluorescence quantitative polymerase chain reaction (FQ-PCR). Results Median macroscopic and microscopic esophagitis scores in groups A' (n=10) and B' (n=8) were 1.0 and 1.5,and 2.0 and 2.5, respectively. There were no significant differences in the macroscopic or microscopic esophagitis scores between the two groups (Z=-0.330, P=0.741; Z=-0.142, P=0.887, respectively). Immunohistochemical staining showed that HSP27 was

    Pseudoepitheliomatous hyperplasia is a benign condition that may be caused by prolonged inflammation, chronic infection, and/or neoplastic conditions of the mucous membranes or skin. Due to its histological resemblance to well-differentiated squamous cell carcinoma, pseudoepitheliomatous hyperplasia may occasionally be misdiagnosed as squamous cell carcinoma. The importance of pseudoepitheliomatous hyperplasia is that it is a self-limited condition that must be distinguished from squamous cell carcinoma before invasive treatment. We report here on a rare case of esophageal pseudoepitheliomatous hyperplasia in a 67-year-old Korean woman with a lye-induced esophageal stricture. Although esophageal pseudoepitheliomatous hyperplasia is infrequently encountered, pseudoepitheliomatous hyperplasia should be considered in the differential diagnosis of esophageal lesions.

    We evaluated the CT scans of 13 patients with spontaneous subcapsular or perinephric hemorrhage (SPH) associated with these underlying causes: 4 angiomyolipomas, 2 renal cell carcinomas, 1 renal metastatic malignant melanoma, 1 ruptured renal artery aneurysm, 1 adrenal myelolipoma, 1 ruptured renal abscess, 2 ruptured hemorrhagic cysts, and 1 patient with undiagnosed coagulation disorder. Our objective was to ascertain whether an underlying cause of SPH was identifiable by CT, and to determine the extension of the hematomas. Computed tomography identified the hematoma in all 13 cases (sensitivity 100 %). In all 12 cases in which there was a renal or adrenal anatomic lesion, the underlying cause was identified with CT (100 %), with correct diagnosis in 11 cases (91.6 %). The case in which no lesion was identified was the undiagnosed coagulation disorder. We conclude that CT is a useful technique for the initial evaluation of SPH, permitting diagnosis of hemorrhage and identification of the underlying cause. (orig.). With 6 figs., 1 tab.

    Reversible cerebral vasoconstriction syndromes (RCVS) comprise a group of disorders characterized by prolonged, but reversible vasoconstriction of the cerebral arteries, usually associated with acute-onset, severe, recurrent headaches, with or without additional neurological signs and symptoms. Various complications of this condition have been observed, such as cortical subarachnoid hemorrhages (cSAH), intracerebral hemorrhages, reversible posterior leukoencephalopathy, ischaemic strokes and transient ischaemic attacks. It is important to include RCVS in thunderclap headache differential diagnosis and among non-aneurismatic subarachnoid hemorrhage causes. In the past years, thanks to the major diffusion of new diagnostic tools such as magnetic resonance, computed tomography and digital subtraction angiography, RCVS have been demonstrated to be more frequent than previously thought. We report an illustrative case of a woman affected by a small cSAH, associated to RCVS, after elective triplet cesarean delivery. To our knowledge, this is the first case of cSAH associated to RCVS after a triplet pregnancy.

    Propylthiouracil (PTU) is a drug that's used to manage hyperthyroidism and it can, on rare occasions, induce antineutrophil cytoplasmic antibody-associated vasculitis that involved multiple organ systems and it can also cause extremely rare isolated or diffuse pulmonary hemorrhage. We report here on a case of a patient who develop diffuse pulmonary hemorrhage after she had been taking PTU for five years. The patient is a 33-year-old woman who presented with hemoptysis. Simple chest radiographs and the chest CT showed bilateral ground-glass opacity, consolidation and pulmonary arterial hypertension. The bronchoalveolar lavage fluid revealed alveolar hemorrhage. The laboratory values showed increased perinuclear-antineutrophil cytoplasmic antibody ({rho} - ANCA) and anti-peroxidase antibody titers.

    During moderate actual or simulated hemorrhage, as cardiac output decreases, reductions in systemic vascular conductance (SVC) maintain mean arterial pressure (MAP). Heat stress, however, compromises the control of MAP during simulated hemorrhage, and it remains unknown whether this response is due...... to a persistently high SVC and/or a low cardiac output. This study tested the hypothesis that an inadequate decrease in SVC is the primary contributing mechanism by which heat stress compromises blood pressure control during simulated hemorrhage. Simulated hemorrhage was imposed via lower body negative pressure...... (LBNP) to presyncope in 11 passively heat-stressed subjects (increase core temperature: 1.2 ± 0.2°C; means ± SD). Cardiac output was measured via thermodilution, and SVC was calculated while subjects were normothermic, heat stressed, and throughout subsequent LBNP. MAP was not changed by heat stress...

    Full Text Available AIMS AND OBJECTIVE Bilateral internal iliac artery ligation is a useful skill for the management of life-threatening post-partum hemorrhage. The procedure is not without risks and long-term complications. This study was conducted to ensure documentation and reporting of pregnancies following bilateral hypogastric artery ligation in cases of post-partum hemorrhage. We also aimed to compare the menstrual function and reproductive outcome after bilateral internal iliac artery ligation done for atonic post-partum haemorrhage. DESIGN Prospective Case Study. SETTING Department of Obstetrics and Gynaecology, Institute of Obstetrics and Gynaecology, Madras Medical College and Hospital, Chennai, Jan 2013 to March 2015. PARTICIPANTS Ten cases of bilateral internal iliac artery ligation were done for atonic post-partum hemorrhage. Main outcome measures: The primary outcome was assessed as the resumption of menstruation, regular cycles, and ability to conceive after surgery. Secondary outcome was incidence of intrauterine growth retardation and recurrent post-partum hemorrhage in subsequent pregnancies. RESULTS The mean duration of resumption of menstruation following internal iliac artery ligation was 3 months. Bilateral internal iliac artery ligation is preferred over unilateral ligation as the extensive collaterals from the contralateral side immediately fill the circulation. The cases of atonic post-partum hemorrhage may require B-Lynch sutures in addition to bilateral internal iliac artery ligation to regain tone. Successful pregnancy after bilateral internal iliac artery ligation occurred in three out of seven cases. In one case, there was intrauterine growth retardation in eighth month. The patient was admitted and closely monitored with Doppler scan. At 35 weeks of gestation, emergency lower segment caesarean section was done for absent diastolic flow. The preterm neonate was 2 kilograms. There was no post-partum hemorrhage in the subsequent

    Full Text Available Dengue hemorrhagic fever leading to hemorrhage in pituitary adenoma is not reported till date: We herein report the first case of bilateral visual loss secondary to pituitary adenoma hemorrhage associated with dengue hemorrhagic fever. Urgent transnasal trans sphenoidal decompression of the macroadenoma prevented permanent visual loss in this patient. Pituitary apoplexy should be considered as differential diagnosis of visual deterioration apart from retinal hemorrhage, maculopathy, and optic neuropathy in cases of dengue hemorrhagic fever. Early decompression of optic nerves helped in the restoration of vision.

    Full Text Available We illustrate the case of a 41-year-old male with allergic manifestations since childhood. He sought medical attention for intermittent, progressive dysphagia from which he had been suffering for a number of years, having felt the sensation of a retrosternal lump and a self-limited obstruction to the passage of food. Endoscopy detected a submucosal tumor in the upper third of the esophagus, which was typified, via biopsy, as a granular cell tumor with benign characteristics and probably responsible for the symptoms. Two years later, the patient sought medical attention once again as these symptoms had not abated, hence digestive endoscopy was repeated. This revealed stenosis of the junction between the middle and lower thirds of the organ which had not been detected previously but was passable under gentle pressure. Eosinophilic esophagitis was detected after biopsies were taken. Esophageal manometry identified a motor disorder affecting the esophageal body. Following three months of treatment using fluticasone propionate applied topically, the symptoms went into remission, esophageal stenosis disappeared and the esophageal biopsies returned to normal. This is the first documented case of the link between granular cell tumors and Eosinophilic esophagitis, two different disorders which could cause dysphagia in young patients.

    Background Vascular hyporeactivity, which occurs in the terminal stage of hemorrhagic shock, is believed to be critical for treating hemorrhagic shock. The present study was designed to examine whether the CB1 cannabinoid receptor (CB1R) was involved in the development of vascular hyporeactivity in rats suffering from hemorrhagic shock.Methods Sixteen animals were randomly divided into two groups (n=8 in each group): sham-operated (Sham) and hemorrhagic shock (HS) groups. Hemorrhagic shock was induced by bleeding. The mean arterial pressure (MAP) was reduced to and stabilized at (25±5) mmHg for 2 hours. The vascular reactivity was determined by the response of MAP to norepinephrine (NE). In later experiments another twelve animals were used in which the changes of CB1R mRNA and protein in aorta and superior mesenteric artery (SMA) were analyzed by RT-PCR and Western blotting. In addition, we investigated the effects of a CB1R antagonist on the vascular hyporeactivity and survival rates in rats with hemorrhagic shock. Survival rates were analyzed by the Fisher's exact probability test. The MAP response was analyzed by one-way analysis of variance (ANOVA).Results Vascular hyporeactivity developed in all animals suffering from hemorrhagic shock. The expression of CB1R mRNA and protein in aorta and 2-3 branches of the SMA were significantly increased in the HS group after the development of vascular hyporeactivity when compared to those in Sham group. When SR141716A or AM251 was administered, the MAP response to NE was (41.75±4.08) mmHg or (44.78±1.80) mmHg respectively, which was higher than that in saline groups with (4.31±0.36) mmHg (P<0.01). We also showed an increased 4-hour survival rate in the SR141716A or AM251-treated group with 20% or 30%, but with a statistically significant difference present between the AM251-treated and saline groups (P<0.05).Conclusions CB1R is involved in vascular hyporeactivity resulting from hemorrhagic shock in rats, and CB1R

    Full Text Available In this paper, we created a decision-making model to detect intracranial hemorrhage and adopted Expectation Maximization(EM segmentation to segment the Computed Tomography (CT images. In this work, basically intracranial hemorrhage is classified into two main types which are intra-axial hemorrhage and extra-axial hemorrhage. In order to ease classification, contrast enhancement is adopted to finetune the contrast of the hemorrhage. After that, k-means is applied to group the potential and suspicious hemorrhagic regions into one cluster. The decision-making process is to identify whether the suspicious regions are hemorrhagic regions or non-regions of interest. After the hemorrhagic detection, the images are segmented into brain matter and cerebrospinal fluid (CSF by using expectation-maximization (EM segmentation. The acquired experimental results are evaluated in terms of recall and precision. The encouraging results have been attained whereby the proposed system has yielded 0.9333 and 0.8880 precision for extra-axial and intra-axial hemorrhagic detection respectively, whereas recall rate obtained is 0.9245 and 0.8043 for extra-axial and intra-axial hemorrhagic detection respectively.

    It is constrictive-stenotic arteriopathy developing in the remote period together with delayed ischemic affliction of the brain resulting in formation of persistent neurological deficit, disability of the patient or fatality that is regarded as the most important pathogenetic mechanism of unfavourable functional and vital prognosis of cerebral hemorrhage. Examined in the trial were 350 patients presenting with cerebral hemorrhage induced by rupture of the brain arterial aneurysms. 300 patients were treated with the drug preparation solcoseryl, 50 patients were the control group. A clinical and paraclinical monitoring of the state of the patients was conducted with the aid of an X-ray computerized tomography, ultrasound dopplerography of the extra- and intracranial arteries. A positive effect is shown of the drug on the risk of development of a clinically manifested neurological deficit that does not undergo regression against the background of paraclinically recordable objective signs of constrictive-stenotic arteriopathy and formation of unfavourable (gross disability, vegetative state, fatality) outcome as per the Glasgow Scale of Outcomes and a low level of the functional activity according to the Barttel's index at day 30 following the development of hemorrhage. The drug is well-tolerated and can be recommended in the treatment of aneurysmatic cerebral hemorrhages.

    Full Text Available The aim of this study was to investigate histomorphological and immunophenotypic features in pill-induced esophagitis. We comparatively evaluated the histomorphological, immunophenotypic features of pill-induced esophagitis vs. reflux esophagitis, as well as clinical information and endoscopic findings. Fifty-two tissue pieces from 22 cases of pill-induced esophagitis, 46 pieces from 20 reflux esophagitis, and 16 pieces from 14 control samples were subjected to immunohistochemistry for inflammatory infiltrates (CD3 for T lymphocyte, CD20 for B lymphocyte, CD56 for NK cell, CD68 for macrophage, CD117 for mast cell and eosinophil chemotaxis-associated proteins (Erk, leptin, leptin receptor, pSTAT3, phospho-mTOR. As a result, Histomorphology showed that a diffuse pattern of dilated intercellular spaces was more frequently observed in pill-induced esophagitis, while reactive atypia and subepithelial papillary elongation were more often found in reflux esophagitis (P < 0.05, respectively. Interestingly, intraepithelial eosinophilic microabscess, intraepithelial pustule and diffuse pattern of dilated intercellular spaces were observed in 14% (3 cases, 9% (2 cases and 32% (7 cases of pill-induced esophagitis, respectively, but in no cases of reflux esophagitis. Regarding intraepithelial inflammatory infiltrates in pill-induced esophagitis, T lymphocytes were the most common cells, followed by eosinophil; 11 and 7 in one x400 power field, respectively. Intraepithelial pSTAT3-positive pattern was more frequently observed in pill-induced esophagitis than in reflux esophagitis, at 45% (10 cases versus 10% (2 cases, respectively (P < 0.05. Considering the distal esophageal lesion only, intraepithelial pustule, diffuse dilated intercellular spaces and stromal macrophages were more frequently found in distal pill-induced esophagitis, whereas reactive atypia and intraepithelial mast cells in reflux esophagitis (P < 0.05, respectively.

    Gastroesophageal reflux disease (GERD) is a commondisorder of the gastrointestinal tract. In the last fewdecades, new technologies have evolved and havebeen applied to the functional study of the esophagus,allowing for the improvement of our knowledge of thepathophysiology of GERD. High-resolution manometry(HRM) permits greater understanding of the function ofthe esophagogastric junction and the risks associatedwith hiatal hernia. Moreover, HRM has been found tobe more reproducible and sensitive than conventionalwater-perfused manometry to detect the presenceof transient lower esophageal sphincter relaxation.Esophageal 24-h pH-metry with or without combinedimpedance is usually performed in patients withnegative endoscopy and reflux symptoms who havea poor response to anti-reflux medical therapy toassess esophageal acid exposure and symptom-refluxcorrelations. In particular, esophageal 24-h impedanceand pH monitoring can detect acid and non-acid refluxevents. EndoFLIP is a recent technique poorly appliedin clinical practice, although it provides a large amountof information about the esophagogastric junction.In the coming years, laryngopharyngeal symptomscould be evaluated with up and coming non-invasive orminimally invasive techniques, such as pepsin detectionin saliva or pharyngeal pH-metry. Future studies arerequired of these techniques to evaluate their diagnostic accuracy and usefulness, although the available dataare promising.

    2016-02-01

    Full Text Available Introduction: Achalasia is a rare disorder, particularly in pediatrics, characterized by esophageal aperistalsis and inadequate relaxation of the lower esophageal sphincter. Its etiology remains unclear. Cases: We describe two adolescents with dysphagia for solids and liquids, vomiting, weight loss and nocturnal cough for a few months. Initially it was considered to be an eating disorder, and the diagnosis of achalasia was reached later by esophageal manometry in one case and by intraoperative biopsy in another. The patients were submitted to Heller myotomy with an antireflux procedure, laparoscopically in one case, and by laparotomy in another, both with a favorable outcome. Discussion/Conclusions: We emphasize the rarity and diagnostic challenge of these cases. The nonspecific symptoms often lead to the diagnosis of an eating disorder, delaying the correct treatment. If symptoms persist achalasia must be considered and the esophageal manometry is the diagnostic test of choice. The gold standard in treatment is surgical, and we highlight the effectiveness of the techniques applied.

    The esophagus serves to transport food and fluid from the pharynx to the stomach. Manometry has been the "golden standard" for the diagnosis of esophageal motility diseases for many decades. Hence, esophageal function is normally evaluated by means of manometry even though it reflects the squeeze force (force in radial direction) whereas the bolus moves along the length of esophagus in a distal direction. Force measurements in the longitudinal (axial) direction provide a more direct measure of esophageal transport function. The technique used to record axial force has developed from external force transducers over in-vivo strain gauges of various sizes to electrical impedance based measurements. The amplitude and duration of the axial force has been shown to be as reliable as manometry. Normal, as well as abnormal, manometric recordings occur with normal bolus transit, which have been documented using imaging modalities such as radiography and scintigraphy. This inconsistency using manometry has also been documented by axial force recordings. This underlines the lack of information when diagnostics are based on manometry alone. Increasing the volume of a bag mounted on a probe with combined axial force and manometry recordings showed that axial force amplitude increased by 130% in contrast to an increase of 30% using manometry. Using axial force in combination with manometry provides a more complete picture of esophageal motility, and the current paper outlines the advantages of using this method.

    Acute esophageal necrosis (AEN) is extremely rare and the pathogenesis of this is still unknown. We report a case of AEN caused by alcohol abuse. In our case, the main pathogenesis could be accounted for low systemic perfusion caused by severe alcoholic lactic acidosis. After the healing of AEN, balloon dilatation was effective to manage the stricture.

    Objective To investigate the diagnostic value of miniprobe ultrasonography (MPS) in the protruding lesions of esophagus. Methods Sixty-two patients with protruding lesions of esophagus were examined with MPS. Results The MPS examination showed diseases of esophageal polyp, inflammatory protruding, esophageal leiomyoma, esophageal leiomyosarcoma, esophageal venous aneurysm, esophageal lipoma, esophageal cyst, esophageal carcinoma, and extra esophageal compression including aorta compression, lung tumor compression and spina compression. Fourteen patients were verified by surgical operations and pathological examinations, resulting in 92.86% (13/14) diagnosis accuracy rate. Forty-eight cases had results of gastroscope examination consistent with that of MPS. Twelve cases had results of CT and MRI examination consistent with that of MPS. Follow-up was completed on 22 patients. Conclusion Besides imaging the esophageal layer, MPS can precisely locate the histological layer of the esophageal protruding lesions and predict their characters. This indicates its value in the diagnosis and differential diagnosis of the protruding lesions of esophagus. Furthermore, the miniature probe used in MPS examination can pass the structured esophagus, enabling wider application of the examination.

    Full Text Available CONTEXT: It has been demonstrated that the ageing process affects esophageal motility. OBJECTIVES: To evaluate the effect of the age on the proximal esophageal response to wet swallows. METHOD: We measured the proximal esophageal response to swallows of a 5 mL bolus of water in 69 healthy volunteers, 20 of them aged 18-30 years (group I, 27 aged 31-50 years (group II, and 22 aged 51-74 years (group III. We used the manometric method with continuous perfusion. The proximal esophageal contractions were recorded 5 cm from a pharyngeal recording site located 1 cm above the upper esophageal sphincter. The time between the onset of the pharyngeal and of the proximal esophageal recording (pharyngeal-esophageal time and the amplitude, duration and area under the curve of the proximal esophageal contraction were measured. RESULTS: The pharyngeal-esophageal time was shorter in group I subjects than in group II and III subjects (P<0.05. The duration of proximal esophageal contractions was longer in group I than in groups II and III (P<0.001. There was no differences between groups in the amplitude or area under the curve of contractions. There were no differences between groups II and III for any of the measurements. CONCLUSION: We conclude that the age may affects the response of the proximal esophagus to wet swallows.

    AIM: To elucidate the mechanism of restenosis following balloon dilation of benign esophageal stenosis.METHODS: A total of 49 rats with esophageal stenosis were induced in 70 rats using 5 ml of 50 % sodium hydroxide solution and the double-balloon method, and an esophageal restenosis (RS) model was developed by esophageal stenosis using dilation of a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter. These 49 rats were divided into two groups: rats with benign esophageal stricture caused by chemical burn only (control group, n=21) and rats with their esophageal stricture treated with balloon catheter dilation (experimental group, n=28). Imaging analysis and immunohistochemistry were used for both quantitative and qualitative analyses of esophageal stenosis and RS formation in the rats, respectively.RESULTS: Cross-sectional areas and perimeters of the esophageal mucosa layer, muscle layer, and the entire esophageal layers increased significantly in the experimental group compared with the control group. Proliferating cell nuclear antigen (PCNA) was expressed on the 5th day after dilation, and was still present at 1 month. Fibronectin (FN)was expressed on the 1st day after dilation, and was still present at 1 month.CONCLUSION: Expression of PCNA and FN plays an important role in RS after balloon dilation of benign esophageal stenosis.

    We describe a unique technique to promote a nonsurgical esophageal anastomosis with magnets in children with esophageal atresia. To evaluate the efficacy of magnetic lengthening of atretic esophageal ends to produce an anastomosis and to communicate our results after more than 2 years of follow-up. Between September 2001 and March 2004, five children were selected for treatment. Two of the children had esophageal atresia without fistula (type A) and three had atresia with fistula converted to type A surgically; however, surgeons failed to achieve an anastomosis because of the width of the gap. Neodymium-iron-boron magnets were used. Daily chest radiographs were taken until union of the magnets was observed. They were then replaced with an orogastric tube. Anastomosis was achieved in all patients in an average of 4.8 days. One patient, with signs of early sepsis, was successfully treated with antibiotics. In four of the five patients, esophageal stenosis developed. At the time of this report, two patients were free of treatment and on an oral diet (after 26 months), two patients required periodic balloon dilatation, and one patient had recently undergone surgery due to recurrent esophageal stenosis not amenable to balloon dilatation. Magnetic esophageal anastomosis is a feasible method in selected patients with esophageal atresia. Esophageal anastomosis was achieved in all patients. The only observed complication of significance was esophageal stenosis. One patient needed surgery because of stenosis. (orig.)

    The pathological constriction of cerebral arteries known as cerebral vasospasm (CVS) is with a delay of 4 to 10 days linked to subarachnoid hemorrhage. Several agents have been suggested as being responsible; amongst these perhaps 5-hydroxytryptamine (5-HT) and endothelin-1 (ET-1) are the most...... prominent given their ability to elicit powerful constriction of cerebral arteries. Investigating both 5-HT and ET receptors we have observed that there are distinct changes in receptor phenotype after experimental SAH, namely upregulation of the ETB and 5-HT1B receptors, and that this upregulation...

    Full Text Available Uncontrolled hemorrhage, resulting from traumatic injuries, continues to be the leading cause of death in civilian and military environments. Hemorrhagic deaths usually occur within the first 6 hours of admission to hospital; therefore, early prehospital identification of patients who are at risk for developing shock may improve survival. The aims of the current study were: 1. To establish and characterize a unique model of uncontrolled internal hemorrhage induced by massive renal injury (MRI, of different degrees (20-35% unilateral nephrectomy in rats, 2. To identify early biomarkers those best predict the outcome of severe internal hemorrhage. For this purpose, male Sprague Dawley rats were anesthetized and cannulas were inserted into the trachea and carotid artery. After abdominal laparotomy, the lower pole of the kidney was excised. During 120 minutes, hematocrit, pO2, pCO2, base excess, potassium, lactate and glucose were measured from blood samples, and mean arterial pressure (MAP was measured through arterial tracing. After 120 minutes, blood loss was determined. Statistical prediction models of mortality and amount of blood loss were performed. In this model, the lowest blood loss and mortality rate were observed in the group with 20% nephrectomy. Escalation of the extent of nephrectomy to 25% and 30% significantly increased blood loss and mortality rate. Two phases of hemodynamic and biochemical response to MRI were noticed: the primary phase, occurring during the first 15 minutes after injury, and the secondary phase, beginning 30 minutes after the induction of bleeding. A Significant correlation between early blood loss and mean arterial pressure (MAP decrements and survival were noted. Our data also indicate that prediction of outcome was attainable in the very early stages of blood loss, over the first 15 minutes after the injury, and that blood loss and MAP were the strongest predictors of mortality.

    Highlights: • We report our experiences with stent-grafts for the treatment of acute hemorrhage from the hepatic artery or the stump of the gastroduodenal artery. • The technical success of stent-graft implantation was 88%. • The bleeding ceased immediately after stent-graft implantation in 88%. • The complication rate was 21%. - Abstract: Purpose: We evaluated the technical success and clinical efficacy of stent-graft implantation for the emergency management of acute hepatic artery bleeding. Methods: Between January 2010 and July 2013, 24 patients with hemorrhage from the hepatic artery were scheduled for emergency implantation of balloon expandable stent-grafts. The primary study endpoints were technical and clinical success, which were defined as successful stent-graft implantation with sealing of the bleeding site at the end of the procedure, and cessation of clinical signs of hemorrhage. The secondary study endpoints were complications during the procedure or at follow-up and 30-day mortality rate. Results: In 23 patients, hemorrhage occurred after surgery, and in one patient hemorrhage occurred after trauma. Eight patients had sentinel bleeding. In most patients (n = 16), one stent-graft was implanted. In six patients, two overlapping stent-grafts were implanted. The stent-grafts had a target diameter between 4 mm and 7 mm. Overall technical success was 88%. The bleeding ceased after stent-graft implantation in 21 patients (88%). The mean follow-up was 137 ± 383 days. In two patients, re-bleeding from the hepatic artery occurred during follow-up after 4 and 29 days, respectively, which could be successfully treated by endovascular therapy. The complication rate was 21% (minor complication rate 4%, major complication rate 17%). The 30-day mortality rate was 21%. Conclusions: Implantation of stent-grafts in the hepatic artery is an effective emergency therapy and has a good technical success rate for patients with acute arterial hemorrhage.

    Full Text Available Esophageal cancer is the second and third most common malignancy in Iranian malesand females, respectively, claiming lives of approximately 5800 Iranians each year.Squamous cell carcinoma (SCC is presently the most common type accounting forabout 90% of all esophageal cancers in Iran. Recent studies have shown that there isa gradual increase in the incidence of adenocarcinoma of the distal esophagus alongwith gastric cardia adenocarcinoma. Thirty-five years ago, the age standardizied rate (ASR of esophageal SCC in thecity of Gonbad (Golestan Province, northeast of Iran was found to be one of the highestrates for any single cancer that had been reported worldwide (ASR >100/105/year.Recent studies have shown that the incidence of SCC in Gonbad has declined to lessthan half of what it was in the past. This decline in the incidence of esophageal SCCparallels an improvement in the socioeconomic situation of people living in thisregion. According to recent cancer registry data in Iran there is still an obviousintracountry variability between the incidence of esophageal cancer in the south withan ASR of 3 for males and 2 for females in Kerman and 43 and 36 in the northeasternprovince of Golestan. The reasons for this very high rate of SCC in northeastern Iranhave been the subject of several studies during the past 35 years. According to resultsof these studies the suspected risk factors are: low intake of fruits and vegetables, drinkinghot tea, consumption of opium products and tobacco, H.pyloriinfection in the stomach,using unhealthy drinking water from cisterns and genetic susceptibility. The mainsuspected mutagens are polycyclic aromatic hydrocarbons (PAH and N-nitrosocompounds. In order to embark primary and secondary prevention of this fatal cancer,further prospective studies are presently underway in the region. The Golestanesophageal cancer cohort study which follows of 50,000 subjects is on going. We expectsimple and feasible evidence based

    Viral hemorrhagic fever (VHF) is defined as virus infections that usually cause pyrexia and hemorrhagic symptoms with multiple organ failure. VHF includes following viral infections: Ebola hemorrhagic fever (EHF), Marburg hemorrhagic fever (MHF), Crimean-Congo hemorrhagic fever (CCHF) and Lassa fever. In particular, the causative agents of EHF, MHF, CCHF, and Lassa fever are Ebola, Marburg, CCHF, Lassa viruses, respectively, and regarded as biosafety level-4 pathogens because of their high virulence to humans. Recently, relatively large outbreaks of EHF and MHF have occurred in Africa, and areas of EHF- and MHF-outbreaks seem to be expanding. Although outbreaks of VHF have not been reported in Japan, there is a possibility that the deadly hemorrhagic fever viruses would be introduced to Japan in future. Therefore, preparedness for possible future outbreaks of VHF is necessary in areas without VHF outbreaks.

    Moyamoya disease is a rare cerebrovascular anomaly involving the intracranial carotid arteries that can present clinically with either ischemic or hemorrhagic disease. Moyamoya syndrome, indistinguishable from moyamoya disease at presentation, is associated with multiple clinical conditions including neurofibromatosis type 1, autoimmune disease, prior radiation therapy, Down syndrome, and Turner syndrome. We present the first reported case of an adult patient with previously unrecognized mosaic Turner syndrome with acute subarachnoid and intracerebral hemorrhage as the initial manifestation of moyamoya syndrome. A 52-year-old woman was admitted with a subarachnoid hemorrhage with associated flame-shaped intracerebral hemorrhage in the left frontal lobe. Physical examination revealed short stature, pectus excavatum, small fingers, micrognathia, and mild facial dysmorphism. Cerebral angiography showed features consistent with bilateral moyamoya disease, aberrant intrathoracic vessels, and an unruptured 4-mm right superior hypophyseal aneurysm. Genetic analysis confirmed a diagnosis of mosaic Turner syndrome. Our case report is the first documented presentation of adult moyamoya syndrome with subarachnoid and intracerebral hemorrhage as the initial presentation of mosaic Turner syndrome. It illustrates the utility of genetic evaluation in patients with cerebrovascular disease and dysmorphism.

    Evaluation of the esophagus is helpful in determining the source of chest pain. Eighteen per cent of 72 patients with a normal coronary angiogram had esophageal disease as a source of chest pain. Eight had diffuse esophageal spasm, four had reflux esophagitis and one had an esophageal ulcer. Five of eight patients with diffuse esophageal spasm had relief of symptoms with nitroglycerin. Despite normal coronary arteriogram and normal esophageal manometry 42 of 49 other patients had relief of chest pain with nitroglycerin.

    Full Text Available Abstract Background Anesthesia is indispensable for in vivo research but has the intrinsic potential to alter study results. The aim of the current study was to investigate the impact of three common anesthesia protocols on physiological parameters and outcome following the most common experimental model for subarachnoid hemorrhage (SAH, endovascular perforation. Methods Sprague-Dawley rats (n = 38 were randomly assigned to (1 chloral hydrate, (2 isoflurane or (3 midazolam/medetomidine/fentanyl (MMF anesthesia. Arterial blood gases, intracranial pressure (ICP, mean arterial blood pressure (MAP, cerebral perfusion pressure (CPP, and regional cerebral blood flow (rCBF were monitored before and for 3 hours after SAH. Brain water content, mortality and rate of secondary bleeding were also evaluated. Results Under baseline conditions isoflurane anesthesia resulted in deterioration of respiratory parameters (arterial pCO2 and pO2 and increased brain water content. After SAH, isoflurane and chloral hydrate were associated with reduced MAP, incomplete recovery of post-hemorrhagic rCBF (23 ± 13% and 87 ± 18% of baseline, respectively and a high anesthesia-related mortality (17 and 50%, respectively. Anesthesia with MMF provided stable hemodynamics (MAP between 100-110 mmHg, high post-hemorrhagic rCBF values, and a high rate of re-bleedings (> 50%, a phenomenon often observed after SAH in humans. Conclusion Based on these findings we recommend anesthesia with MMF for the endovascular perforation model of SAH.

    The aim of this preliminary study was to evaluate the predictive value of esophageal clearance scintigraphy (ECS) in the diagnosis of esophageal autonomic neuropathy in diabetic patients without any esophageal symptoms. A single swallon ECS was performed in 12 diabetic patients and 15 normal volunteers, and esophageal transit time (ETT) and esophageal (Es) T 1/2 values were calculated. ETT and Es 1/2 were found to be significantly prolonged in the diabetic group (p<0.01 and p<0.05, respectively). In this preliminary study, our results strongly suggest that ECS may be an important noninvasive diagnostic tool in the evaluation of diabetic patients with asymptomatic esophageal autonomic neuropathy.

    Technetium-99m albumin-sucralfate ((/sup 99m/Tc)Su) can be used to demonstrate peptic ulcer disease in man and animals. We evaluated the usefulness of (/sup 99m/Tc)Su for detecting various grades of esophagitis. (/sup 99m/Tc)Su adhered to the distal esophagus for up to 3 hr in five of six patients with esophageal ulcers but adhered to only two of nine with lesser degrees of esophagitis. No adherence was seen in five patients without esophagitis. Thus, (/sup 99m/Tc)Su may not be useful for detecting any but the most severe grade of esophagitis. Based on these results, we speculate that the previously documented beneficial effects of sucralfate on mild to moderate esophagitis may be due to other mechanisms besides adherence to the ulcerated mucosa.

    Dissecting aneurysms of the middle cerebral artery (MCA) are known to cause cerebral infarcts in younger people and can also cause subarachnoid hemorrhage (SAH) or intracranial hemorrhage. Bleeding caused by an isolated dissecting aneurysm of the MCA is relatively rare. We report the case of a young woman with SAH that occurred subsequent to a ruptured dissecting aneurysm of the MCA which resolved spontaneously as demonstrated by angiography.

    Full Text Available The goal of this study was to investigate the effect of hypertonic saline with 6% Dextran-70 (HSD resuscitation on organ damage and the resuscitation efficiency of the combination of HSD and lactated ringers (LR in a model of hemorrhage shock in dogs.Beagles were bled to hold their mean arterial pressure (MAP at 50 ± 5 mmHg for 1 h. After hemorrhage, beagles were divided into three groups (n = 7 to receive pre-hospital resuscitation for 1 h (R1: HSD (4 ml/kg, LR (40 ml/kg, and HSD+LR (a combination of 4 ml/kg HSD and 40 ml/kg LR. Next, LR was transfused into all groups as in-hospital resuscitation (R2. After two hours of observation (R3, autologous blood was transfused. Hemodynamic responses and systemic oxygenation were measured at predetermined phases. Three days after resuscitation, the animals were sacrificed and tissues including kidney, lung, liver and intestinal were obtained for pathological analysis.Although the initial resuscitation with HSD was shown to be faster than LR with regard to an ascending MAP, the HSD group showed a similar hemodynamic performance compared to the LR group throughout the experiment. Compared with the LR group, the systemic oxygenation performance in the HSD group was similar but showed a lower venous-to-arterial CO2 gradient (Pv-aCO2 at R3 (p < 0.05. Additionally, the histology score of the kidneys, lungs and liver were significantly lower in the HSD group than in the LR group (p < 0.05. The HSD+LR group showed a superior hemodynamic response but higher extravascular lung water (EVLW and lower arterial oxygen tension (PaO2 than the other groups (p < 0.05. The HSD+LR group showed a marginally improved systemic oxygenation performance and lower histology score than other groups.Resuscitation after hemorrhagic shock with a bolus of HSD showed a similar hemodynamic response compared with LR at ten times the volume of HSD, but HSD showed superior efficacy in organ protection. Our findings suggest that

    Neurogenic pulmonary edema (NPE) is observed in cerebral injuries and has an impact on treatment results, being a predictor of fatal prognosis. In this study we retrospectively reviewed medical records of 250 consecutive patients with aneurysmal subarachnoid hemorrhage (SAH) for the frequency and treatment results of NPE. The following factors were taken under consideration: clinical status, aneurysm location, presence of NPE, intracranial pressure (ICP), and mortality. All patients had plain- and angio-computer tomography performed. NPE developed most frequently in case of the aneurysm located in the anterior communicating artery. The patients with grades I-III of SAH, according to the World Federation of Neurosurgeons staging, were immediately operated on, while those with poor grades IV and V had only an ICP sensor's implantation procedure performed. A hundred and eighty five patients (74.4 %) were admitted with grades I to III and 32 patients (12.8 %) were with grade IV and V each. NPE was not observed in SAH patients with grade I to III, but it developed in nine patients with grade IV and 11 patients with grade V. Of the 20 patients with NPE, 19 died. Of the 44 poor grade patients (grades IV-V) without NPE, 20 died. All poor grade patients had elevated ICP in a range of 24-56 mmHg. The patients with NPE had a greater ICP than those without NPE. Gender and age had no influence on the occurrence of NPE. We conclude that the development of neurogenic pulmonary edema in SAH patients with poor grades is a fatal prognostic as it about doubles the death rate to almost hundred percent.

    Full Text Available CONTEXT: Esophageal cancer is often diagnosed at an advanced stage and has a poor prognosis. Most patients with advanced esophageal cancer have significant dysphagia that contributes to weight loss and malnutrition. Esophageal stenting is a widespread palliation approach, but unsuitable for cancers near the upper esophageal sphincter, were stents are poorly tolerated. Generally, guidelines do not support endoscopic gastrostomy in this clinical setting, but it may be the best option for nutritional support. OBJECTIVE: Retrospective evaluation of patients with dysphagia caused advanced esophageal cancer, no expectation of resuming oral intake and with percutaneous endoscopic gastrostomy for comfort palliative nutrition. METHOD: We selected adult patients with unresecable esophageal cancer histological confirmed, in whom stenting was impossible due to proximal location, and chemotherapy or radiotherapy were palliative, using gastrostomy for enteral nutrition. Clinical and nutritional data were evaluated, including success of gastrostomy, procedure complications and survival after percutaneous endoscopic gastrostomy, and evolution of body mass index, albumin, transferrin and cholesterol. RESULTS: Seventeen males with stage III or IV squamous cell carcinoma fulfilled the inclusion criteria. Mean age was 60.9 years. Most of the patients had toxic habits. All underwent palliative chemotherapy or radiotherapy. Gastrostomy was successfully performed in all, but nine required prior dilatation. Most had the gastrostomy within 2 months after diagnosis. There was a buried bumper syndrome treated with tube replacement and four minor complications. There were no cases of implantation metastases or procedure related mortality. Two patients were lost and 12 died. Mean survival of deceased patients was 5.9 months. Three patients are alive 6, 14 and 17 months after the gastrostomy procedure, still increasing the mean survival. Mean body mass index and laboratory

    For the better understanding of esophageal motility, the muscle texture and the distribution of skeletal and smooth muscle fibers in the esophagus are of crucial importance. Esophageal physiology will be shortly mentioned as far as necessary for a comprehensive understanding of peristaltic disturbances. Besides the pure depiction of morphologic criteria, a complete esophageal study has to include an analysis of the motility. New diagnostic tools with reduced radiation for dynamic imaging (digital fluoroscopy, videofluoroscopy) at 4-30 frames/s are available. Radiomanometry is a combination of a functional pressure measurement and a simultaneous dynamic morphologic analysis. Esophageal motility disorders are subdivided by radiologic and manometric criteria into primary, secondary, and nonclassifiable forms. Primary motility disorders of the esophagus are achalasia, diffuse esophageal spasm, nutcracker esophagus, and the hypertonic lower esophageal sphincter. The secondary motility disorders include pseudoachalasia, reflux-associated motility disorders, functionally caused impactions, Boerhaave's syndrome, Chagas' disease, scleroderma, and presbyesophagus. The nonclassificable motility disorders (NEMD) are a very heterogeneous collective. (orig.)

    2017-03-01

    Full Text Available The corpus callosum is the major commissural pathway connecting the cerebral hemispheres. This pathway receives its blood supply from anterior communicating artery, pericallosal artery, and posterior pericallosal artery. However, in some cases, the entire corpus callosum is supplied by median callosal artery; thus, occlusion of this artery can lead to infarction of the entire corpus callosum. Few reports have described this type of infarction, and no reports after subarachnoid hemorrhage (SAH exist. Here, we report on a 42-year-old female who was diagnosed with SAH after two aneurysms were discovered in bifurcation of left anterior cerebral artery (A1-A2. After successful clipping was performed, the patient was alert and had no neurological deficits; moreover, the computed tomography images that were acquired after the operation showed no evidence of infarction. Nine days after admittance to the hospital, drowsiness and weakness of the left limbs with brain swelling appeared and decompressive hemi-craniectomy was performed. Diagnostic cerebral angiography revealed vasospasms in both anterior and middle cerebral arteries, thus fasudil hydrochloride was administered intra-arterially. While blood flow in all arteries improved, diffusion-weighted magnetic resonance imaging detected infarction along the entire length of the corpus callosum and in the medial region of the right frontal lobe. We believe this infarction was due to secondary ischemia of median callosal artery. This case reminded us of the anatomical variation wherein median callosal artery is the sole blood supply line for the corpus callosum and demonstrated that infarction of the entire corpus callosum is possible.

    Esophageal duplication cyst is a rare congenital embryonal gastrointestinal (GI) malformation which is diagnosed most commonly in childhood. In adults, they can present with a variety of symptoms ranging from dysphagia, chest pain, epigastric discomfort, and vomiting to more serious complications including infections, hemorrhage, and ulcerations. A 30-year-old male presented with gradually progressive dysphagia to solids for 4 months without significant weight loss. Clinical examination and routine laboratory examination were unrevealing. Upper GI endoscopy revealed a well-defined submucosal lesion bulging into the esophageal lumen involving the right antero-lateral wall of the distal esophagus. The overlying mucosa was normal with mild luminal narrowing but gastroscope could be negotiated across this narrowing. Differential diagnosis included lipoma, leiomyoma or GI stromal tumors. Contrast-enhanced computed tomography of thorax revealed a 3.5 × 2.3 × 3 cm well-defined homogenous hypodense lesion involving the right antero-lateral wall of the distal thoracic esophagus with likely possibility of submucosal or intramural lesion. Subsequently, endoscopic ultrasonography (EUS) revealed a 3.3 × 2.8 cm homogenous hypoechoic lesion without any vascularity involving the distal esophagus wall suggestive of duplication cyst. The lesion was intramural in location as muscularis propria was seen to go around the lesion. Bronchogenic cyst was excluded due to absence of cartilage and close proximity of the cyst to lumen. Fine-needle aspiration was not attempted in view of high risk of introducing infection. Being symptomatic, the patient underwent complete surgical excision of the cyst with exteriorization of the base which on histopathology confirmed duplication cyst. Esophageal duplication cysts are exceedingly rare congenital embryonal malformations with estimated prevalence of 0.0122% arising from aberration of posterior division of embryonic foregut at 3 - 4 weeks of

    In 1992, a 63 year-old woman complained of dysphagia and chest pain, and was diagnosed with esophageal achalasia. Three years later, she developed resting tremor, cog-wheel rigidity, and retro-pulsion, and was diagnosed with Parkinson's disease and given appropriate medication. Several years later, intractable vomitting and aspiration pneumonia developed, and the lower esophageal sphincter was dilated using a pneumatic balloon dilator under gastroscopic guidance in 2004. That procedure improved her symptoms and the esophageal dilation was visualized on chest CT images. Herein, we report this rare case of esophageal achalasia followed by Parkinson's disease and discuss the relationship between the two diseases.

    Full Text Available Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation.

    We report two patients with lingual dyskinesia and complaints of food regurgitation following long-term antipsychotic therapy. Esophageal contrast radiography revealed dyskinetic movements extending from the pharynx to the upper portion of the esophagus. The elevation of intraesophageal pressure was confirmed by esophageal manometry. The dyskinetic movements almost disappeared along with improvement of lingual dyskinesia following the administration of sulpiride in one patient. Another patient suddenly died due to asphyxiation of foods before the beginning of treatment. We termed this life-threatening movement, 'esophageal dyskinesia'. It should be emphasized that 'esophageal dyskinesia' associated with lingual dyskinesia is a potentially fatal adverse reaction to antipsychotic therapy.

    Abstract Introduction Esophageal intramural pseudodiverticulosis is a rare condition characterized by the dilatation of the submucosal glands. Case presentation We present a case of esophageal intramural pseudodiverticulosis in a 72-year-old Caucasian man who presented with dysphagia and with a background history of alcohol abuse. An upper gastrointestinal endoscopy of our patient showed an esophageal stricture with abnormal mucosal appearances, but no malignant cells were seen at biopsy. Appearances on a barium esophagram were pathognomonic for esophageal intramural pseudodiverticulosis. Conclusion We demonstrate the enduring usefulness of barium esophagography in the characterization of abnormal mucosal appearances at endoscopy.

    2011-03-01

    Isolated unilateral pulmonary artery agenesis is a rare congenital anomaly that may be complicated with hemoptysis, recurrent pulmonary infections or pulmonary hypertension. To our knowledge the occurrence of a coronary syndrome associated with a coronary-to-bronchial artery saccular aneurysmal collateralization has never been described before. A 44-year-old female presented a congenital right pulmonary artery agenesis associated with a hypotrophic and multicystic right lung complicated with recurrent bronchitis. This patient had a coronary syndrome for which the coronary artery imaging showed a coronary-to-bronchial artery collateralization with an aneurysm at this level. It gives rise to a coronary syndrome by coronary steal. Two bronchial collaterals arising from a diaphragmatic artery and the subclavian artery were also found on the computed tomography (CT)-scan. This last collateral also showed another saccular aneurysm. We first performed an embolization of those two aneurysms in order to decrease the risk of hemorrhage and coronary steal, before performing a right pneumonectomy. In this case, the surgery was indicated because of the pathological lung and the risk of postembolization ischaemia. The postoperative course was uneventful and the patient was doing well six months later.

Presented is the common factor of the onset of this complication, it's diagnosis, and therapy. Listed below are the diagnoses and operative procedures used on these eight patients. Cysta Aerea Permagna Lobi Inf. Pulm. Dexter/operation: Mytomis Longitudinalis Ooesophagi. Caverna Bronchiectatica Permagna Lobi Inferior Pulmo Dexter/operation: Lobestomia Typica. Echinococcus Heaptis Complicatus, Empyema Pleurae Dexter/opetation: Decorticatio. Haemathorax Spontaneous Lobus Sinister/operation: Decorticatio Pleurae Sinister. Echi Comp. Cupolae Hepatis Permagnus/operation: Thoracotomia Phrenotomia, evacuatio, Triplex Drainage. Bronchiectasiae Lobi Medius et Inferior Pulmo Dexter/operation: Biblobectomia Typica. Carcinoma Bronchi Lobi Inferior Pulmo Dexter/operation: Lobectomia Typica. Gastric problems had troubled four of these eight patients in their past history. Bleeding in three patients occurred three days postoperatively, and in the remaining five, thirty days following their operation. Six patients had to be treated conservatively because of serious contraindications to reoperation. Four of them expired. Autopsy revealed: Pyothorax, Dehiscention Bronchi, Empyema, and Gastritis Errosiva with multiulcerations, hemoragia, and dilatation of the right heart. Two patients with recent stress ulcers were reoperated on, and were cured. The authors estimate that the occurrence of hemorrhaging stress ulcer following thoracic surgery are basically due to Hypoxia. The chain of events whic brought about the stress ulcer, however, began even before the operation, continued throughout the operation, and appeared postoperatively due to postoperative complications. The authors point out that these complications can be foreseen (early and late), but firstly, an attempt should be made to treat the patient with conservative therapy. Inasmuch as the hemorrhaging

    Full Text Available No abstract available. Article truncated after 150 words. A 29 year old woman with history of a Whipple procedure for pancreatic cancer and nonalcoholic steatohepatitis cirrhosis presented with a massive upper gastrointestinal bleeding (UGIB likely from esophageal varices and developed hemorrhagic shock. Emergent upper endoscopy could not be performed due to hemodynamic instability. Therefore, a Minnesota Tube was placed emergently for balloon tamponade of the bleeding. A transjugular intrahepatic portosystemic shunt was also placed emergently to decrease bleeding by reducing portal pressure. By this time, the patient had received 4 liters of normal saline, 14 units of packed red blood cells, 6 units of platelets, and 4 units of fresh frozen plasma. The Minnesota tube did control the bleeding somewhat, however, there was continued bloody drainage from the stomach port of the Minnesota tube. The patient’s abdomen became remarkably distended and was dull to percussion throughout. A CT scan of the abdomen and pelvis revealed severe dilatation of ...

    Full Text Available Leptospirosis is one of the most widespread zoonoses in the world, although the mechanisms responsible for the pathogenesis of spirochetes of the genus Leptospira are largely unknown. Human infection occurs either by direct contact with infected animals or indirectly, through contact with water or soil contaminated with urine, as the spirochetes easily penetrate human skin. The present report exposes the case of a female patient, diagnosed with leptospirosis after having had contact with a dog infected by Leptospira sp. that developed pulmonary hemorrhage, acute respiratory distress syndrome and acute renal failure.

    Full Text Available Subarachnoid hemorrhage (SAH is the bleeding into the subarachnoid space containing cerebrospinal fluid. The most common cause of SAH is trauma. Rupture of aneurysms, vascular anomalies, tumor bleeds and hypertension are other important etiologies. SAH in the setting of pituitary tumor can result from various causes. It can be due to intrinsic tumor related pathology, injury to surrounding the vessel during the operative procedure or due to an associated aneurysm. We discuss the pathological mechanisms and review relevant literature related to this interesting phenomenon. Early and accurate diagnosis of the cause of the SAH in pituitary tumors is important, as this influences the management.

    A 38-year-old woman was admitted to our hospital with a 3-day history of severe headache associated with some nausea and vomiting. MRI did not show any evidence of subarachnoid hemorrhage, but MRA and CTA showed an aneurysm on the paraclinoid region of the right internal carotid artery. She was successfully treated by coil embolization. MRA taken 7 days after the treatment showed marked vasospam. Fortunately, her therapeutic course was uneventful and she was discharged without any neurological deficits. Vasospasm without subarachnoid hemorrhage is a rare event. Here, we review the literature and discuss potential mechanisms for vasospasm in the absence of subarachnoid hemorrhage.

    Full Text Available While blunt trauma of the head and neck are a common pattern of injury, significant problems related to the prompt diagnosis and optimal management of traumatic artery injuries have been reported in the literature. While patients with major artery injuries might develop hemorrhagic shock very rapidly, patients with blunt cerebrovascular injuries (BCVI can present asymptomatic, but complications like basilar territory infarction, cortical blindness and death may occur. We report the life- and limb-saving management in a 57-year-old hemodynamically unstable trauma patient. The individual developed hemorrhagic shock, and other major complications, including cortical blindness, related to a posterior circulation stroke. Full recovery was achieved by immediate endovascular prosthesis for subclavian artery (SA rupture and stenting of a traumatic vertebral artery occlusion. Endovascular and alternative treatment options are discussed and the management of subsequent sequelae associated with aggressive anticoagulation in trauma patients is reviewed, including intracranial, abdominal and other sites of secondary hemorrhage.

    Eosinophilic esophagitis (EE) is the most frequent condition found in a group of gastrointestinal disorders called eosinophilic gastrointestinal diseases.The hypothetical pathophysiological mechanism is related to a hypersensitivity reaction.Gastroesophageal reflux disease-like complaints not ameliorated by acid blockade or occasional symptoms of dysphagia or food impaction are likely presentations of EE.Due to its unclear pathogenesis and unspecific symptoms,it is difficult to diagnose EE without a strong suspicion.Although histological criteria are necessary to diagnosis EE,there are some characteristic endoscopic features.We present the case of a healthy 55-year-old woman with dysphagia and several episodes of esophageal food impaction over the last six months.This case report stresses the most distinguishing endoscopic findings-mucosa rings,white exudative plaques and linear furrows-that can help in the prompt recognition of this condition.

    We examined 11 pediatric patients with eosinophilic esophagitis with a tardy diagnosis. The symptoms were initially thought to be related to other diseases, leading to the use of inadequate therapeutic approaches. The patients were between 3 and 17 years old (mean 7.8 ± 3.8 years), and 8 of the patients were male. Common symptoms included abdominal pain, regurgitation, difficulty in gaining weight, vomiting, dysphagia, and coughing. The mean age for the onset of symptoms was 4.3 ± 2.9 years. Endoscopic findings included normal mucosa in five (45%) patients, thickening of the mucosa with longitudinal grooves in three (27%), erosive esophagitis in two (18%), and a whitish stippling in one (9%) patient. Treatment included the use of a topical corticosteroid for 10 patients. In eight (73%) cases, the treatment made the symptoms disappear. Ten patients underwent histopathological management after treatment, with a decrease in the number of eosinophils. PMID:24106430

    Aim: To discuss the merits of "tubes treatment" for esophageal fistula (EF). Methods: A 66-year-old female who suffered from a bronchoesophageal and esophagothoratic fistula underwent a successful "three tubes treatment" (close chest drainage, negative pressure suction at the leak, and nasojejunal feeding tube), combination of antibiotics, antacid drugs and nutritional support. Another 55-year-old male patient developed an esophagopleural fistula (EPF) after esophageal carcinoma operation. He too was treated conservatively with the three tubes strategy as mentioned above towards a favorable outcome. Results:The two patients recovered with the tubes treatment, felt well and became able to eat and drink, presenting no complaint. Conclusion: Tubes treatment is an effective basic way for EF. It may be an alternative treatment option.

    2013-06-01

    Full Text Available Background: Everolimus, a potent mammalian target of rapamycin (mTOR inhibitor, has shown anticancer activity against various types of cancer, including renal cell carcinoma (RCC; however, little information is available on the efficacy and safety of the combination of everolimus and radiotherapy. We report a case of radiation-induced esophagitis that might have been exacerbated by the sequential administration of everolimus. Case Presentation: A 63-year-old Japanese man with RCC complained of back pain, and magnetic resonance imaging revealed vertebral metastases. He received radiotherapy (30 Gy/10 fractions to the T6-10 vertebrae. Everolimus was administered immediately after the completion of radiotherapy. One week later, he complained of dysphagia, nausea and vomiting. An endoscopic examination of the esophagus showed erosive esophagitis in the middle to lower portions of his thoracic esophagus, corresponding to the irradiation field. Conclusion: Clinicians should be aware that everolimus might lead to the unexpected exacerbation of radiation toxicities.

    Thoracoscopic approaches for esophageal cancer are still disparate. Complete scopic technique is feasible for esophagectomy. Mini-thoracotomy is effective for excellent exposure of the mediastinum for lymph node dissection. The magnifying effect of a video, by keeping the camera in close proximity to the dissection is essential to perform the same quality of dissection as open surgery. The benefit, for respiratory morbidity, remains to be studied in a large number of patients. Minimizing the chest wall injury contributed, to the reduction of constrictive pulmonary damage. Survival after the thoracoscopic approach was favorably compared with open surgery, when extensive lymphadenectomy was performed. Because the efficacy improves with the surgeon's experience, satisfactory outcome will only be obtained in a center performing a sufficient volume of esophageal surgery to provide the surgeon with opportunities to refine his necessary skills. Improvements in technique and instrumentation should make the procedure more accessible and steepen the learning curve.

    Surgical treatment of esophageal cancer is largely palliative. To clarify the indication it is necessary to assess the effectiveness of the palliation in relief of dysphagia and the operative risks. In a retrospective study we analyzed the perioperative morbidity and follow-up in 25 patients with carcinoma of the esophagus treated between 1984 and 1988 (5 years). With combined anesthesia, early extubation and intensive pulmonary therapy, no perioperative respiratory insufficiency was observed. Perioperative mortality was 0%. An anastomotic leak in 2 patients with a cervical anastomosis was healed in both cases by conservative management. On hospital discharge all patients were able to eat normally. 13 patients died after 1 year on average (4 months to 3 years). 12 patients are alive 6 months to 4 years after operation, 10 of them without symptoms. Our results show that with optimal perioperative management of esophageal carcinoma low morbidity is possible and good palliation of dysphagia is feasible.

    Postoperative bilateral adrenal hemorrhage is a rare but potentially life-threatening complication. This diagnosis is often missed because the symptoms and laboratory results are usually nonspecific. We report a case of bilateral adrenal hemorrhage associated with acute primary adrenal insufficiency following laparoscopic cholecystectomy. The knowledge of this uncommon complication following any abdominal surgery allows timey diagnosis and rapid treatment.

    We have reviewed initial diagnostic features, treatment, and outcome in 29 patients with acute subarachnoid hemorrhage due to non-traumatic vertebrobasilar artery dissection diagnosed in our hospital between 1993 and 2003. The dissections occurred in the vertebral artery in 19 patients, the posterior inferior cerebellar artery (PICA) in two patients, the basilar artery in four patients, and in the vertebral artery extending into the PICA in four patients. A pseudoaneurysm was found in 20 patients. Clinical manifestations typically included sudden onset of moderate to severe headache, nuchal rigidity, and drowsiness. Fourteen patients were treated conservatively. Fifteen patients underwent endovascular treatment with either parent artery occlusion (13 patients) or aneurysmal coil occlusion with preservation of the parent artery (2 patients). Re-bleeding occurred within 12 days and before treatment in nine patients. Eight of these had a pseudoaneurysm. No patient bled after endovascular treatment. Poor grade and early re-bleeding were associated with less favorable outcome. Outcome at 6 months did not differ significantly between endovascular and conservative treatment. Altogether, good recovery was achieved for 16 patients, moderate disability was seen in one, severe disability in four, and eight patients (27%) died. The absence of bleeding subsequent to endovascular treatment in this study suggests that endovascular treatment may be a rational approach in these patients at high risk of re-bleeding, especially those with a pseudoaneurysm.

Utilizing a multidisciplinary team approach starting from the initial staging evaluation ensures that all members are in agreement with the plan of care. Treatment selection for esophageal and gastric cancer often involves a combination of chemotherapy, radiation, surgery, and palliative interventions (endoscopic and surgical, and direct communication between specialists in these fields is needed to ensure appropriate clinical decision making. At the University of Colorado, the Esophageal and Gastric Multidisciplinary Clinic was created to bring together all experts involved in treating these diseases at a weekly conference in order to provide patients with coordinated, individualized, and patient-centered care. This review details the essential elements and benefits of building a multidisciplinary program focused on treating esophageal and gastric cancer patients.

    Xinmailong injection solution was invented at 1988 by prof. Li Shunan in Dali medical college. It was made from the material which has high biological activeness to the cardiac and vascular system. During the experimental shock caused by excessive loss of blood in monkey and dog, it was found by ECG that the T-wave of anterion lead on left chest elevated and became high and sharp after acute blood loss. Arterial blood pressure dropped to 8-5.3 kPa for dog and 8-5.3-2.7 kPa for monkey, changes of T-wave all recovered to near normal level after xinmailong solution was injected intravenously (0.05-0.2 mL/kg). These Results implied that xinmailong might improve the ischemia of myocardium induced by hemorrhagic shock.

    Nasogastric tube insertion is a routine procedure in medical care. However, misplacement of the tube can cause a variety of complications, which can be life threatening in some instances. We report a case of fatal hemorrhagic shock immediately after nasogastric tube insertion in a patient undergoing debridement by video-assisted thoracoscopic surgery for mediastinitis. Emergency endoscopy showed that the bleeding came from the nasogastric tube which had perforated the esophagus and possibly tore an intrathoracic large vessel. The nasogastric tube insertion was considered to have directly produced the perforation because no esophageal perforation had been found on preoperative endoscopy. Factors contributing to the risk of esophageal perforation in this case included coexisting mediastinitis, surgical manipulation, endotracheal intubation, inability to cooperate during general anesthesia, and repetitive advancement of the nasogastric tube. Prompt clamping of the nasogastric tube or delayed insertion after failed attempts might have improved the outcome. This report illustrates the complication of massive bleeding that can occur immediately after misplaced insertion of a nasogastric tube. Extraordinary care should be taken to avoid misplacement of the nasogastric tube during insertion.

    Troponin (tr) elevation in aneurysmal subarachnoid hemorrhage (SAH) patients is often difficult to be appropriately assessed by clinicians, causing even disagreements regarding its management between neurosurgeons and cardiologists. The purpose of this article was to review the literature regarding the clinical interpretation of tr elevation in SAH. We searched for articles in PubMed using the key words:“troponin elevation”and“subarachnoid hemorrhage”. All of them, as well as relative neurosurgical books, were used for this review. Some type of cardiovascular abnormality develops in most SAH patients. Neurogenic stunned myocardium is a frequent SAH complication, due to catecholamine surge which induces cardiac injury, as evidenced by increased serum tr levels, electrocardiographic (ECG) changes and cardiac wall motion abnormalities. Tr elevation, usually modest, is an early and specific marker for cardiac involvement after SAH and its levels peak about two days after SAH. Cardiac tr elevation predictors include poor clinical grade, intraventricular hemorrhage, loss of consciousness at ictus, global cerebral edema, female sex, large body surface area, lower systolic blood pressure, higher heart rate and prolonged Q-Tc interval. Elevated tr levels are associated with disability and death (especially tr>1μg/L), worse neurological grade, systolic and diastolic cardiac dysfunction, pulmonary congestion, longer intensive care unit stay and incidence of vasospasm. Tr elevation is a common finding in SAH patients and constitutes a rightful cause of worry about the patients’ cardiac function and prognosis. It should be therefore early detected, carefully monitored and appropriately managed by clinicians.

  8. Effect of Aneurysmal Subarachnoid Hemorrhage on Word Generation

    2014-01-01

    Full Text Available Background. Aneurysmal subarachnoid hemorrhage (aSAH survivors commonly exhibit impairment on phonemic and semantic fluency tests; however, it is unclear which of the contributing cognitive processes are compromised in aSAH patients. One method of disentangling these processes is to compare initial word production, which is a rapid, semiautomatic, frontal-executive process, and late phase word production, which is dependent on more effortful retrieval and lexical size and requires a more distributed neural network. Methods. Seventy-two individuals with aSAH and twenty-five control subjects were tested on a cognitive battery including the phonemic and semantic fluency task. Demographic and clinical information was also collected. Results. Compared to control subjects, patients with aSAH were treated by clipping and those with multiple aneurysms were impaired across the duration of the phonemic test. Among patients treated by coiling, those with anterior communicating artery aneurysms or a neurological complication (intraventricular hemorrhage, vasospasm, and edema showed worse output only in the last 45 seconds of the phonemic test. Patients performed comparably to control subjects on the semantic test. Conclusions. These results support a “diffuse damage” hypothesis of aSAH, indicated by late phase phonemic fluency impairment. Overall, the phonemic and semantic tests represent a viable, rapid clinical screening tool in the postoperative assessment of patients with aSAH.

  9. Highly Absorbent Antibacterial Hemostatic Dressing for Healing Severe Hemorrhagic Wounds

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available To accelerate healing of severe hemorrhagic wounds, a novel highly absorbent hemostatic dressing composed of a Tencel®/absorbent-cotton/polylactic acid nonwoven base and chitosan/nanosilver antibacterial agent was fabricated by using a nonwoven processing technique and a freeze-drying technique. This study is the first to investigate the wicking and water-absorbing properties of a nonwoven base by measuring the vertical wicking height and water absorption ratio. Moreover, blood agglutination and hemostatic second tests were conducted to evaluate the hemostatic performance of the resultant wound dressing. The blending ratio of fibers, areal weight, punching density, and fiber orientation, all significantly influenced the vertical moisture wicking property. However, only the first two parameters markedly affected the water absorption ratio. After the nonwoven base absorbed blood, scanning electron microscope (SEM observation showed that erythrocytes were trapped between the fibrin/clot network and nonwoven fibers when coagulation pathways were activated. Prothrombin time (PT and activated partial thromboplastin time (APTT blood agglutination of the resultant dressing decreased to 14.34 and 50.94 s, respectively. In the femoral artery of the rate bleeding model, hemostatic time was saved by 87.2% compared with that of cotton cloth. Therefore, the resultant antibacterial wound dressing demonstrated greater water and blood absorption, as well as hemostatic performance, than the commercially available cotton cloth, especially for healing severe hemorrhagic wounds.

    Background Methylprednisolone (MP), a synthetic glucocorticosteroid, has been broadly studied in experiments on endotoxin-induced shock and septic shock. This study was designed to ascertain whether glycine and MP can protect against organ injury and death caused by hemorrhagic shock, and to elucidate the underlying mechanisms of these protective effects in rats.Method To establish a shock model, Wistar rats were bled to maintain mean arterial pressure at 30-50 mmHg for 1 hour and subsequently resuscitated with the shed blood and normal saline. Just prior to resuscitation, the rats were randomly assigned to four groups: sham group (operation performed without inducing shock), shock group, shock+glycine group (glycine injected at the beginning of resuscitation) and shock+MP group (MP injected at the beginning of resuscitation).Conclusion Glycine and MP reduce organ injury and mortality caused by hemorrhagic shock by preventing increase of intracellular calcium levels in Kupffer cell, suppressing Kupffer cell activation, decreasing the production of TNF-α by Kupffer cells, and blocking systemic inflammatory responses.

    BACKGROUND: We investigated the association between hemorrhagic stroke and migraine using data from The Health Improvement Network database. FINDINGS: We ascertained 1,797 incident cases of intracerebral hemorrhage (ICH) and 1,340 of subarachnoid hemorrhage (SAH). Density-based sampling was used...... to select 10,000 controls free from hemorrhagic stroke. Using unconditional logistic regression models, we calculated the risk of hemorrhagic stroke associated with migraine, adjusting for age, sex, calendar year, alcohol, body mass index, hypertension, previous cerebrovascular disease, oral contraceptive...... use, and health services utilization.The risk (odds ratio [OR]) of ICH among migraineurs was 1.2 (95% confidence interval [CI] 0.9-1.5), and of SAH was (1.2, 95% CI 0.9-1.5). The association with ICH was stronger for migraine diagnosed ≥20 years prior to ICH (OR 1.6, 95% CI 1.0-2.4), but not with SAH...

    Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments. This review summarizes the evidence on EoE pathophysiology and illustrates the safety and efficacy of the most recent medical and endoscopic treatments.

    OBJECTIVE To determine the ideal method of surgical preoperative treatment for perforation with esophageal carcinoma.METHODS 36 cases of perforation with esophageal carcinoma were treated surgically in this series.Perforations occurred into the right lung in14 cases ,the mediastinum in 17 cases and trachea in 5 cases.Open thoracic surgery was performed in 34 cases,in which the right thoracic approach using a 3-incision method was applied in 16 cases,and operation by stages in 15 cases.Of the 34 cases,retrosternal substitution of the esophagus with stomach or colon was performed in 26 cases.RESULTS Surgery was successful in 31 cases and operative death occurred in 3 cases.The postoperative follow up study was from 3~72months.Of these cases 15 wree alive at 7~12 months, 2 at 24 months,and 1 at 72 months. The results can be considered satisfactory.CONCLUSION The therapeutic results of surgical treatment of perforation with esophageal carcinoma were markedly superior to that of conventional conservative treatment. The authors suggest that surgical intervention without delay should be undertaken for patients having a perforation with carcinoma of the esophagus. A right thoracic approach with a 3-incision method (retrosternal replacement of esophagus with stomach or colon) or operation by stages is preferable.

    Full Text Available Herpes simplex virus is a common cause of ulcerative esophagitis in the immunocompromised or debilitated host. Despite a high prevalence of primary and recurrent Herpes simplex virus infection in the general population, Herpes simplex virus esophagitis (HSVE appears to be rare in the immunocompetent host. We report three cases of endoscopically-diagnosed HSVE in apparently immunocompetent children; the presentation was characterized by acute onset of fever, odynophagia, and dysphagia. In two cases, the diagnosis was confirmed histologically by identification of herpes viral inclusions and culture of the virus in the presence of inflammation. The third case was considered to have probable HSVE based on the presence of typical cold sore on his lip, typical endoscopic finding, histopathological evidence of inflammation in esophageal biopsies and positive serologic evidence of acute Herpes simplex virus infection. Two cases received an intravenous course of acyclovir and one had self-limited recovery. All three cases had normal immunological workup and excellent health on long-term follow-up.

    AIM: To summarize the operative experiences for giant leiomyoma of esophagus.METHODS: Eight cases of giant esophageal leiomyoma (GEL) whose tumors were bigger than 10 cm were treated surgically in our department from June 1980 to March 2004.and esophagoscopy. Leiomyoma located in upper thirds of the esophagus in one case, middle thirds of the esophagus in five cases, lower thirds of the esophagus in two cases. Resection of tumors was performed successfully in all of these cases. Operative methods included transthoracic extramucosal enucleation and buttressing the muscular defect with pedicled great omental flap (one case), esophagectomy and esophagogastrostomy above the arch of aorta (three cases), total esophagectomy and esophageal replacement with colon (four cases). Histological examination confirmed that all of these cases were leiomyoma.RESULTS: All of the eight patients recovered approvingly with no mortality and resumed normal diet after operation. Vomiting during meals occurred in one patient with esophagogastrostomy, and remained 1 mo. Reflux esophagitis occurred in one patient with esophagogastrostomy and was alleviated with medication. Thoracic colon syndrome (TCS) occurred in one patient with colon replacement at 15 mo postoperatively. No recurrence occurred in follow-up from 6 mo to 8 years.CONCLUSION: Surgical treatment for GEL is both safe and effective. The choices of operative methods mainly depend on the location and range of lesions. We prefer to treat GEL via esophagectomy combined with esophagogastrostomy or esophagus replacement with colon. The long-time quality of life is better in the latter.

    As a minimally invasive treatment of esophageal achalasia per-oral endoscopic myotomy( POEM) was developed in 2008. More than 1,100 cases of achalasia-related diseases received POEM. Success rate of the procedure was more than 95%(Eckerdt score improvement 3 points and more). No serious( Clavian-Dindo classification III b and more) complication was experienced. These results suggest that POEM becomes a standard minimally invasive treatment for achalasia-related diseases. As an off-shoot of POEM submucosal tumor removal through submucosal tunnel (per-oral endoscopic tumor resection:POET) was developed and safely performed. Best indication of POET is less than 5 cm esophageal leiomyoma. A novel endoscopic treatment of gastroesophageal reflux disease (GERD) was developed. Anti-reflux mucosectomy( ARMS) is nearly circumferential mucosal reduction of gastric cardia mucosa. ARMS is performed in 56 consecutive cases of refractory GERD. No major complications were encountered and excellent clinical results. Best indication of ARMS is a refractory GERD without long sliding hernia. Longest follow-up case is more than 10 years. Minimally invasive treatments for esophageal benign diseases are currently performed by therapeutic endoscopy.

    AIM: To analyze the clinical and endoscopic features of Chinese patients with reflux esophagitis (RE).METHODS: A total of 1405 RE patients were analyzed retrospectively. Data on gender, age, presence/absence of H pylori infection and associated esophageal hiatal hernia were collected. Esophagitis was divided into different grades according to Los Angeles Classification.RESULTS: Of 18823 patients, 1405 were diagnosed as RE. The ratio of male to female patients was 1.75:1 (P < 0.01). The mean age of male and female patients was significantly different (P = 0.01). The peak age at onset of the disease was 40-60 years. According to Los Angeles Classification, there were significant differences in the age of patients with grades A and B compared to patients with grades C and D (P < 0.01). Two hundred and seventy-seven patients were infected with H pylori, the infection rate was low (P < 0.01). Complication of esophageal hiatal hernia was found to be significantly associated with the severity of esophagitis and age in 195 patients (P < 0.01). Esophageal mucosa damages were mainly located at the right esophageal wall.CONCLUSION: The peak age of onset of RE is 40-60 years and higher in males than in females. The mean age of onset of RE is lower in males than in females. The infection rate of H pylori is significantly decreased in patients with esophagitis. Old age and esophageal hiatal hernia are associated with more severe esophagitis. Right esophageal mucosal damage can occur more often in RE patients.

    Jian-Bing Wang

    Full Text Available BACKGROUND: To estimate the contribution of tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake to esophageal cancer mortality and incidence in China. METHODOLOGY/PRINCIPAL FINDINGS: We calculated the proportion of esophageal cancer attributable to four known modifiable risk factors [population attributable fraction (PAF]. Exposure data was taken from meta-analyses and large-scale national surveys of representative samples of the Chinese population. Data on relative risks were also from meta-analyses and large-scale prospective studies. Esophageal cancer mortality and incidence came from the 3(rd national death cause survey and population-based cancer registries in China. We estimated that 87,065 esophageal cancer deaths (men 67,686; women: 19,379 and 108,206 cases (men: 83,968, women: 24,238 were attributable to tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake in China in 2005. About 17.9% of esophageal cancer deaths among men and 1.9% among women were attributable to tobacco smoking. About 15.2% of esophageal cancer deaths in men and 1.3% in women were caused by alcohol drinking. Low vegetable intake was responsible for 4.3% esophageal cancer deaths in men and 4.1% in women. The fraction of esophageal cancer deaths attributable to low fruit intake was 27.1% in men and 28.0% in women. Overall, 46% of esophageal cancers (51% in men and 33% in women were attributable to these four modifiable risk factors. CONCLUSIONS/SIGNIFICANCE: Tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake were responsible for 46% of esophageal cancer mortality and incidence in China in 2005. These findings provide useful data for developing guidelines for esophageal cancer prevention and control in China.

    We describe a case of cerebral infarctions caused by transient vasoconstrictions in the posterior circulation 2 weeks after intraventricular hemorrhage without subarachnoid hemorrhage in a 35-year-old patient with Moyamoya disease. To our knowledge, this is the first case report where diffuse segmental vasoconstrictions of the basilar and posterior cerebral arteries were recognized after intraventricular hemorrhage in Moyamoya disease. The patient complained of severe and acute-onset headache 14 days after the intraventricular hemorrhage, which had a different character and severity from the one she complained of at the onset of intraventricular hemorrhage. Finally, headache disappeared within 1 month and vasoconstriction resolved in 2 months. Reversible cerebral vasoconstriction syndrome was under consideration for the etiology of her condition because of the "thunderclap" characteristics of the headache and the delayed timing of occurrence of the vasoconstriction. This case report informs and alerts neurologists, neurosurgeons and neuroradiologists who observe and treat patients with Moyamoya disease that vasoconstriction in the posterior circulation may occur after intraventricular hemorrhage in these patients.

    Dolichoectasia of intracranial arteries is an infrequent disease with an incidence less than 0.05% in general population. It represents 7% of all intracranial aneurysms. Commonly seen in middle age patients with severe atherosclerosis and hypertension, the affected arteries include the basilar artery, supraclinoid segment of the internal carotid artery, middle, anterior and posterior cerebral arteries; males are more frequently affected. The clinical features of these fusiform aneurysms are divided in three categories: ische-mic, cranial nerve compression and signs from mass effect. Hemorrhage may also occur. Nine patients with symptomatic cerebral blood vessel dolichoectasias are presented. Six of them were males with moderate or severe hypertension. Lesions were confined to the basilar artery in 3 cases, carotid arteries and the middle cerebral artery in 1 case, and both systems were affected in 4 patients. Middle cerebral arteries were affected in 5 cases and the anterior cerebral artery in one. An isolated fusiform aneurysm of the posterior cerebral artery is also presented (case 8) (Table 3). Motor or sensory deficits, ataxia, dementia, hemifacial spasm and parkinsonism were observed. One patient died from cerebro-meningeal hemorrhage (Table 2). All patients were studied with computerized axial tomography of the brain, 5 cases with four vessel cerebral angiography, 4 cases with magnetic resonance imaging (MRI) and case 5 with MRI angiography. Clinical symptoms depend on the affected vascular territory, size of the aneurysm and compression of adjacent structures. The histopathologic findings are atheromatous lesions, disruption of the internal elastic membrane and fibrosis of the muscular wall. The resultant is a diffuse deficiency of the muscular wall and the internal elastic membrane. Recent advances in neuroimaging such as better resolution of CT scan, magnetic resonance images (MRI) and MRI angiography increased the diagnosis of this pathology showing

    Background Enhanced characterization of esophageal peristaltic and sphincter function provided by esophageal pressure topography (EPT) offers a potential diagnostic advantage over conventional line tracings (CLT). However, high-resolution manometry (HRM) and EPT require increased equipment costs over conventional systems and evidence demonstrating a significant diagnostic advantage of EPT over CLT is limited. Our aim was to investigate whether the inter-rater agreement and/or accuracy of esophageal motility diagnosis differed between EPT and CLT. Methods Forty previously-completed patient HRM studies were selected for analysis using a customized software program developed to perform blinded independent interpretation in either EPT or CLT (six pressure sensors) format. Six experienced gastroenterologists with a clinical focus in esophageal disease (attendings) and six gastroenterology trainees with minimal manometry experience (fellows) from three academic centers interpreted each of the 40 studies using both EPT and CLT formats. Rater diagnoses were assessed for inter-rater agreement and diagnostic accuracy, both for exact diagnosis and for correct identification of a major esophageal motility disorder. Results The total group agreement was moderate (κ = 0.57; 95% CI 0.56–0.59) for EPT and fair (κ = 0.32; 0.30–0.33) for CLT. Inter-rater agreement between attendings was good (κ = 0.68; 0.65–0.71) for EPT and moderate (κ = 0.46; 0.43–0.50) for CLT. Inter-rater agreement between fellows was moderate (κ = 0.48; 0.45–0.50) for EPT and poor to fair (κ = 0.20; 0.17–0.24) for CLT. Among all raters, the odds of an incorrect exact esophageal motility diagnosis were 3.3 times higher with CLT assessment than with EPT (OR 3.3; 95% CI 2.4–4.5; p<0.0001) and the odds of incorrect identification of a major motility disorder were 3.4 times higher with CLT than EPT (OR 3.4; 2.4–5.0; p<0.0001). Conclusions Superior inter-rater agreement and diagnostic accuracy

    Full Text Available Transesophageal echocardiography (TEE is a commonly used procedure in patients with suspected endocarditis. A rare but dreadful complication of this procedure is perforation of the esophagus. We report the case of an elderly female with multiple comorbidities, who presented with polyarticular septic arthritis. TEE was performed to rule out endocarditis. Though the standard procedure protocol was followed, she developed esophageal perforation. It was managed with esophageal stenting but she developed multiorgan failure and did not survive. This case highlights the potential of severe morbidity and mortality associated with TEE. Appropriate screening must be done and high-risk individuals must be identified before such procedures are attempted.

    Important new advances were presented in esophageal disease in Digestive Disease Week 2013. A highlight was confirmation of the high efficacy of weight loss to treat symptoms of reflux and an interesting pilot study suggesting that a simple ligature with supra- and infracardial bands could be an effective technique in esophageal reflux. If the excellent results and safety and efficacy of this technique are confirmed in the long term, it could revolutionize the management of gastroesophageal reflux disease. Also of note this year was the presentation of multiple studies validating a new technique, peroral endoscopic myotomy (POEM) for the endoscopic treatment of achalasia. This technique seems to have excellent efficacy and safety.

    Bilateral adrenalectomy (ADRX) in rats removes the source of two major stress-responsive hormones, corticosterone and epinephrine. To test how ADRX rats with-stand stress, we performed the following experiments in adult male rats provided with indwelling femoral arterial and venous cannulae and either ADRX or sham-adrenalectomized (Sham) 3 days later and given 0.5% NaCl to drink. Five to 6 days after adrenal surgery the rats were studied after either a 15 ml/kg.5 min hemorrhage or after an overnight fast followed by insulin-induced hypoglycemia. In fed unstressed ADRX rats, basal mean arterial blood pressure was slightly decreased; heart rate was increased; blood volume, vasopressin, and oxytocin concentrations were not different from sham values; and renin and norepinephrine were significantly elevated. The recovery of arterial pressure after hemorrhage in the ADRX rats was similar to that in the sham group over a 5-h period; however, the responses of vasopressin and oxytocin were significantly greater, and those of renin and norepinephrine were markedly potentiated in the ADRX group. Heart rate recovered faster in the ADRX group and was elevated, compared to the sham value, for most of the 5-h period. Restitution of blood volume was attenuated in the ADRX group, although the restitution of plasma protein was not different between the groups. A significant difference in the change in plasma osmolality between groups after hemorrhage may account for the attenuated restitution of blood volume. After an overnight fast, which reduced blood volume in both groups of rats, the plasma renin concentration rose still further in ADRX rats; the differences in other measured variables observed between fed ADRX and sham groups remained the same. The insulin-induced 50% decrease in glucose caused minor effects on arterial blood pressure and heart rate and occasioned responses in renin and norepinephrine of similar magnitudes in the two groups. We conclude that in the absence of

    Full Text Available CONTEXT: Eosinophilic esophagitis is an entity characterized by an esophageal inflammatory infiltrate of eosinophils, manifested by dysphagia, intermittent food impactions and symptoms similar to gastroesophageal reflux disease (GERD, that predominantly affects young adults. There may be association of eosinophilic esophagitis with GERD, and motor abnormalities have been described. OBJECTIVE: The main objectives of this study are to describe the findings at esophageal manometry and pH monitoring in patients with eosinophilic esophagitis. METHODS: Cross-sectional study of 20 patients with a diagnosis of eosinophilic esophagitis, submitted to esophageal manometry and 24h pH monitoring. Were analysed the manometric changes and the presence of abnormal reflux on pH monitoring. RESULTS: Twenty patients (15 men, 5 women had a mean age of 29 years. Motility disorders were found in 25% (5/20 patients with ineffective esophageal motility being the most common finding. pH monitoring revealed abnormal reflux on 25%, without any relationship with manometric findings. CONCLUSIONS: Manometric abnormalities were observed in 25% of patients and abnormal reflux on pH monitoring also in 25%. This study showed no relationship between abnormal reflux and the presence of manometric changes.

    Twelve cases of myocardial infarction as related to strenuous exertion are presented with the pathological findings in several of these cases. Three cases with coronary arteriography are also presented. The pathology of coronary arteriosclerotic plaques and the vulnerability to acute injury is reviewed and discussed. It is concluded that strenuous exertion can cause acute injury to coronary artery plaques due to the unusual stressful whip-like action to which coronary arteries are subject. These injuries may initiate as cracks in the plaques or subintimal hemorrhages and proceed to coronary occlusion and ultimate myocardial infarction. With this concept in mind we use the term of "crack in the plaque" (Black's Crack in the Plaque) to account for the sudden appearance of clinical coronary artery disease appearing during or shortly after exertion, or other stressful situations in patients without previous existing evidence of clinical coronary artery disease. This could also account for exacerbation of symptoms or death occurring after exertion in previously quiescent asymptomatic known coronary artery disease subjects. This concept may explain some of the puzzling features of coronary disease.

    AIM: To determine whether cyclooxygenase-2 (COX-2) was expressed in human esophageal squamous cell carcinoma.METHODS: Quantitative reverse transcription-polymerase chain reaction (RT-PCR), western blotting, immunohistochemistry and immunofluorescence were used to assess the expression level of COX-2 in esophageal tissue.RESULTS: COX-2 mRNA levels were increased by >80-fold in esophageal squamous cell carcinoma when compared to adjacent noncancerous tissue. COX-2 protein was present in 21 of 30 cases of esophageal squamous cell carcinoma tissues, but was undetectable in noncancerous tissue. Immunohistochemistry was performed to directly show expression of COX-2 in tumor tissue.CONCLUSION: These results suggest that COX-2 may be an important factor for esophageal cancer and inhibition of COX-2 may be helpful for prevention and possibly treatment of this cancer.

    Full Text Available Mark R Mawhinney, Robert E GlasgowDepartment of Surgery, Huntsman Cancer Institute at the University of Utah, Salt Lake City, UT, USAAbstract: In recent years, esophageal cancer characteristics and management options have evolved significantly. There has been a sharp increase in the frequency of esophageal adenocarcinoma and a decline in the frequency of squamous cell carcinoma. A more comprehensive understanding of prognostic factors influencing outcome has also been developed. This has led to more management options for esophageal cancer at all stages than ever before. A multidisciplinary, team approach to management in a high volume center is the preferred approach. Each patient should be individually assessed based on type of cancer, local or regional involvement, and his or her own functional status to determine an appropriate treatment regimen. This review will discuss management of esophageal cancer relative to disease progression and patient functional status.Keywords: esophageal adenocarcinoma, squamous cell carcinoma, treatment regimen, disease progression, patient functional status

    The clinical features of 14 infants diagnosed with late hemorrhagic disease of newborn (LHDN), of which 10 did not receive vitamin K prophylaxis, are presented. All infants were exclusively breast-fed and 12 did not have any underlying illness to explain the abnormal coagulation profile. The common presenting symptoms were seizures (71%), vomiting (57%), poor feeding (50%) and altered sensorium (36%). Physical examination shared pallor in all infants and a bulging anterior fontanel in 64%. Intracranial bleed was the predominant manifestation (93%), with CT scan showing intracranial bleed in 78%. Eight infants (57%) succumbed to their illness, while 36%had neurological sequelae. Since LHDN leads to significant morbidity and mortality, it should be prevented by providing vitamin K prophylaxis to all newborns.

    Full Text Available Troponin (tr elevation in aneurysmal subarachnoid hemorrhage (SAH patients is often difficult to be appropriately assessed by clinicians, causing even disagreements regarding its management between neurosurgeons and cardiologists. The purpose of this article was to review the literature regarding the clinical interpretation of tr elevation in SAH. We searched for articles in PubMed using the key words: “troponin elevation” and “subarachnoid hemorrhage”. All of them, as well as relative neurosurgical books, were used for this review. Some type of cardiovascular abnormality develops in most SAH patients. Neurogenic stunned myocardium is a frequent SAH complication, due to catecholamine surge which induces cardiac injury, as evidenced by increased serum tr levels, electrocardiographic (ECG changes and cardiac wall motion abnormalities. Tr elevation, usually modest, is an early and specific marker for cardiac involvement after SAH and its levels peak about two days after SAH. Cardiac tr elevation predictors include poor clinical grade, intraventricular hemorrhage, loss of consciousness at ictus, global cerebral edema, female sex, large body surface area, lower systolic blood pressure, higher heart rate and prolonged Q-Tc interval. Elevated tr levels are associated with disability and death (especially tr >1 μg/L, worse neurological grade, systolic and diastolic cardiac dysfunction, pulmonary congestion, longer intensive care unit stay and incidence of vasospasm. Tr elevation is a common finding in SAH patients and constitutes a rightful cause of worry about the patients' cardiac function and prognosis. It should be therefore early detected, carefully monitored and appropriately managed by clinicians.

    Epidemiological studies have demonstrated that areca quid chewing can be an independent risk factor for developing esophageal cancer. However, no studies are available to elucidate the mechanisms of how areca induces carcinogenesis in the esophagus. Since the areca nut in Taiwan contains a high concentration of safrole, a well-known carcinogenic agent, we analyzed safrole-DNA adducts by the 32P-postlabelling method in tissue specimens from esophageal cancer patients. In total, we evaluated 47 patients with esophageal cancer (16 areca chewers and 31 non-chewers) who underwent esophagectomy at the National Taiwan University Hospital between 1996 and 2002. Of the individuals with a history of habitual areca chewing (14 cigarette smokers and two non-smokers), one of the tumor tissue samples and five of the normal esophageal mucosa samples were positive for safrole-DNA adducts. All patients positive for safrole-DNA adducts were also cigarette smokers. Such adducts could not be found in patients who did not chew areca, irrespective of their habits of alcohol consumption or cigarette smoking (psafrole was also tested in vitro in three esophageal cell lines and four cultures of primary esophageal keratinocytes. In two of the esophageal keratinocyte cultures, adduct formation was increased by treatment with safrole after induction of cytochrome P450 by 3-methyl-cholanthrene. This paper provides the first observation of how areca induces esophageal carcinogenesis, i.e., through the genotoxicity of safrole, a component of the areca juice.

    Full Text Available Objective: to reveal the major regularities and mechanisms of morphological changes in the rat pulmonary circulation arteries in the late posthemorrhagic period and to compare them with age-related features of the vessels. Materials and methods: experiments to generate graduated hemorrhagic hypotension with the blood pressure being maintained at 40 mm Hg were carried out on young (5—6-month albino male Wistar rats. Throughout hypotension and 60 days after blood loss, the blood was tested to determine low and average molecular-weight substances by spectrophotometry and the pro- and antioxidative systems by chemiluminescence. Pulmonary circulation arteries were morphologically studied in young animals, rats in the late posthemorrhagic period and old (24—25-month rats. Results. Sixty-minute hemorrhagic hypotension leads to the development of endotoxemia and imbalance of the pro- and antioxidative systems, the signs of which are observed in the late periods (2 months after hypotension. At the same time, the posthemorrhagic period is marked by the significant pulmonary circulation arterial morphological changes comparable with their age-related alterations in old rat. This shows up mainly in the reorganization of a connective tissue component in the vascular wall: the elevated levels of individual collagen fibers, their structural changes, elastic medial membrane destruction and deformity. At the same time, there is a change in the morphometric parameters of vessels at all study stages while their lowered flow capacity is only characteristic for intraorgan arteries. Conclusion: The increased activity of free radical oxidation and endotoxemia may be believed to be one of the causes of morphological changes in pulmonary circulation arteries in the late posthemorrhagic period, which is similar to age-related vascular alterations. Key words: hemorrhagic hypotension, pulmonary circulation arteries, free radical oxidation, endotoxemia, remodeling, late

    Two patients with Meckel's Cave meningiomas were initially hospitalized as a result of subarachnoid hemorrhage. Four-vessel angiography was necessary to exclude other causes of bleeding while demonstrating these lesions. Apoplectic presentation in both cases led to early diagnosis and successful surgical therapy. A review of the literature reveals subarachnoid hemorrhage to be a rarity in association with meningiomas. The two patients currently reported are believed to be the only examples on record of hemorrhagic meningiomas arising from the region of Meckel's Cave.

    We describe a hemorrhagic chondroid chordoma involving the sella turcica with suprasellar extension. The CT and MRI appearances mimiked a hemorrhagic pituitary adenoma. Chondroid chordoma is a variant composed of elements of both chordoma and cartilaginous tissue. An uncommon bone neoplasm, located almost exclusively in the spheno-occipital region, it is usually not considered in the differential diagnosis of a tumor with acute hemorrhage in the sellar region. We discuss the clinical and radiological characteristics which may allow one to differentiate chondroid chordoma from other tumors of this area. (orig.) With 3 figs., 9 refs.

    The aim of this study was to compare the diagnostic value of post-mortem computed tomography angiography (PMCTA) to conventional, ante-mortem computed tomography (CT)-scan, CT-angiography (CTA) and digital subtraction angiography (DSA) in the detection and localization of the source of bleeding in cases of acute hemorrhage with fatal outcomes. The medical records and imaging scans of nine individuals who underwent a conventional, ante-mortem CT-scan, CTA or DSA and later died in the hospital as a result of an acute hemorrhage were reviewed. Post-mortem computed tomography angiography, using multi-phase post-mortem CTA, as well as medico-legal autopsies were performed. Localization accuracy of the bleeding was assessed by comparing the diagnostic findings of the different techniques. The results revealed that data from ante-mortem and post-mortem radiological examinations were similar, though the PMCTA showed a higher sensitivity for detecting the hemorrhage source than did ante-mortem radiological investigations. By comparing the results of PMCTA and conventional autopsy, much higher sensitivity was noted in PMCTA in identifying the source of the bleeding. In fact, the vessels involved were identified in eight out of nine cases using PMCTA and only in three cases through conventional autopsy. Our study showed that PMCTA, similar to clinical radiological investigations, is able to precisely identify lesions of arterial and/or venous vessels and thus determine the source of bleeding in cases of acute hemorrhages with fatal outcomes.

    Full Text Available Introduction. Stroke is a leading cause of mortality and morbidity in the United States. About 20% of the stroke is hemorrhagic and about 50% of these is due to aneurysmal subarachnoid hemorrhage. A troublesome neuropsychiatric complication of subarachnoid hemorrhage is agitation/aggression. Case Presentation. A 45-year-old man with no prior psychiatric history, sustained subarachnoid hemorrhage. After initial stabilization for 2 days, he underwent craniotomy and clipping of anterior cerebral communicating artery aneurysm. Treatment was continued with labetalol, nimodipine, and levetiracetam. Beginning postoperative day 4, patient developed episodes of confusion and agitation/aggression. Switching of Levetiracetam to valproate did not show any improvement. Psychiatry team tried to manage him with intense nursing intervention and different medications like olanzapine, valproate, lorazepam, and haloperidol. However, patient continued to be agitated and aggressive. Switching from labetalol to metoprolol resulted in dramatic improvement within 3 days. Discussion. Antipsychotics and benzodiazepines are often not sufficiently effective in the control of agitation/aggression in patients with traumatic brain injury and similar conditions. Our case report and the literature review including a cochrane review suggests that beta-blockers may be helpful in this situation.

    A 51-year-old male patient with esophageal cancer and cervical, thoracic and celiac artery lymph node metastases was treated by combination chemotherapy of TS-1 and cisplatin. TS-1 (80 mg/m2/day) was administered for 14 days followed by 14 days rest as 1 course. Cisplatin (70 mg/m2/day) was administered in 24-hour continuous intravenous infusion at day 8 after the start of TS-1. Before treatment, the tumor marker, CEA showed 27,060 ng/ml. After 5 courses of chemotherapy, endoscopy revealed that the primary tumor had disappeared and no cancer cells were detected by endoscopic biopsy. Chest and abdominal CT scan also showed almost total disappearance of the lymph nodes metastases. CEA decreased to 710 ng/ml. No high-grade toxicities (WHO grade 3 or 4) were seen during the chemotherapy. He is now very well. This TS-1/cisplatin chemotherapy regimen might be a useful treatment for metastatic esophageal cancer.

    Background If the emphysema lesions are not symmetrical, unilateral lung volume reduction surgery (LVRS) can be carried out on the more severe side. The aim of this research was to evaluate the feasibility and effects of LVRS performed simultaneously with resection of pulmonary and esophageal neoplasms.Methods Forty-five patients with pulmonary neoplasm and 37 patients with esophageal neoplasm were randomly assigned to group A or group B. In group A, LVRS was performed simultaneously on the same side as thoracotomy. In group B, only tumor resection was performed. The nonfunctional lung area was determined by preoperative chest computed tomography and lung ventilation/perfusion scan. The lung volume removed was about 20% to 30% of the lobes on one side. Preoperative and postoperative indexes including pulmonary function testing variables, arterial blood gas analysis variables, dyspnea scale, 6-minute walk distance, etc., were compared between the groups.Results There were no surgical deaths in this study. The postoperative forced vital capacity in 1 second, PaO_2, PaCO_2,dyspnea scale, and 6-minute walk distance were improved significantly in group A, whereas these indexes did not change or decreased slightly in group B.Conclusions For tumor patients who have associated emphysema, simultaneous LVRS not only increases the chance of receiving surgical therapy, but also improves the postoperative quality of life of the patient. LVRS has expanded thesurgical indication for tumor patients.

    Full Text Available A 36-year-old woman with 3 prior C-sections is diagnosed with a caesarean scar ectopic pregnancy. Despite receiving intramuscular and transvaginal methotrexate injection 2 months before presentation, the beta human chorionic gonadotropin was recorded to be 73 mIU/mL at the time of encounter. The patient complained of vaginal bleeding with a significant drop in hematocrit from 40% to 33%. Transvaginal ultrasound confirmed retroplacental hemorrhage and because of the patient's desire to retain fertility, interventional radiology was consulted to perform an uterine artery embolization. The uterine artery embolization was successful in achieving hemostasis and resulted in a decrease of betaHCG to 46 on postprocedure day 1 to <1 mIU/mL by postoperative week 3.

    Correlation of lesion location and appearance with clinical sequelae in 25 patients with CT-proven frontal lobe hematomas reveals 10 of 25 hematomas were located above the frontal horns of the lateral ventricles. Nine of the 10 patients were normotensive. All presented with contralateral motor and sensory deficits. Four of 25 hematomas were situated inferior to the frontal horns. All these patients were hypertensive, rapidly became comatose and exhibited hemiplegia, hemianestesia and gaze preference contralateral to the hemiplegia. Five patients had frontal hematomas which extended inward from the interhemispheric fissure or caval-septal region. All were normotensive. All had anterior cerebral-anterior communicating artery aneurysms on angiography. Four patients had hematomas involving both the frontal and temporal region. All were normotensive with no known cause for hemorrhage. Two patients had bifrontal hematomas; one had butterfly appearance extending across the interhemispheric fissure and the other was midline but had no interhemispheric blood. Both were normotensive. One had an anterior cerebral-anterior communicating artery aneurysm.

    Full Text Available "nGerminal matrix-intraventricular hemorrhage (IVH is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. The importance of the lesion relates not only to its high incidence but to their attendant complications (IC: hydrocephalus. Brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and hydrocephalus. In this study we have used brain sonography for detection of intraventricular hemorrhage and post hemorrhagic hydrocephalus and their incidences. The studied population was consisted of premature neonate (birth weight equal or less than 1500g and gestational age equal or less than 37 weeks who admitted in Mofid Hospital NICU (Tehran, Iran during a one year period. For all neonate (including criteria brain sonography in first week of life was done and in presence of IVH, serial Brain sonography was done weekly for detection of hydrocephalus. A total of 57 neonate entered the study. Intraventicular-germinal matrix hemorrhage was seen in 64.4% (35 patients. Forty percent of patients with intraventricular-germinal matrix hemorrhage had grade I, 11% grade II, 25.7% grade III, 2.8% grade VI. Hydrocephalus was detected in 20 percent of patients who had intraventricular-germinal matrix hemorrhage. That incidence of IVH in our study in comparison with other area and situation is higher. Hydrocephaly had direct relation with severity of IVH. This shows that with control of risk factor of IVH, we can control Post hemorrhagic hydrocephalus.

    Mechanical compression of coronary artery stents may be associated with a fatal outcome as the result of refractory myocardial ischemia. We present the history of an 83-yr-old patient, who died owing to hemorrhagic shock 3 days after stent implantation, despite immediate cardiopulmonary resuscitation (CPR). Postmortem examination showed stent compression, probably due to mechanical deformation during CPR. This complication has been reported in two other cases in the literature, suggesting that CPR may be hazardous to patients with coronary artery stents.

    Diagnostic imaging is carried out in patients with esophageal carcinoma in order to decide on the therapeutical procedure, to control therapy, to document complications and to assess concomitant diseases.Chest X-rays and esophagograms give a 2-dimensional view of the X-ray absorption ill 3-dimensional examination volumes, the diagnostic accuracy thus being limited by overshadowing. Because of the robust examination technique, the broad availability and the low costs chest X-rays are usually used for short-term controls under therapy and follow-up. Esophagography is carried out in order to asses the exact location and length of a known esophageal carcinoma prior to therapy and in order to assess peristaltic disturbances and fistulas. CT and MRI provide tomographic images with a spatial resolution of up to 1mm3 allowing the reconstruction of high-resolution images not only in the transversal but also in any other plain. The diagnostic accuracy of esophagography is comparatively high in T1 T3 stages (80%-90%). T1 and T2 tumors cannot be diagnosed by CT and MRI, because both methods do not visualize the mucosa(unlike esophagography and endoscopy) and the esophageal wall layers (unlike EUS). Infiltration depth tends to be overestimated in T1 and T2 carcinomas and to be underestimated in T3 and T4 cancers. CT and MRI cannot detect metastases in normally sized lymph nodes and cannot accurately differelltiate between benign and malignant lymphadenopathy in enlarged nodes with a reported sensitivities and spccifities of 60% and 74%, respectively. However, further prospective studies using up to date CT and NIR technology are needed to assess the present diagnostic situation. CT and MRI do not only visualize the inediastinum,but also the lungs, the pleura and the skeleton as well as the neck and the abdomen thus providing a comprehensive overview of the TNM stage in 3 body regions.

  20. Pathophysiological mechanisms linking obesity and esophageal adenocarcinoma

    2014-01-01

    In recent decades there has been a dramatic rise in the incidence of esophageal adenocarcinoma(EAC) in the developed world. Over approximately the same period there has also been an increase in the prevalence of obesity. Obesity, especially visceral obesity, is an important independent risk factor for the development of gastro-esophageal reflux disease, Barrett’s esophagus and EAC. Although the simplest explanation is that this mediated by the mechanical effects of abdominal obesity promoting gastro-esophageal reflux, the epidemiological data suggest that the EAC-promoting effects are independent of reflux. Several, not mutually exclusive, mechanisms have been implicated, which may have different effects at various points along the refluxBarrett’s-cancer pathway. These mechanisms include a reduction in the prevalence of Helicobacter pylori infection enhancing gastric acidity and possibly appetite byincreasing gastric ghrelin secretion, induction of both low-grade systemic inflammation by factors secreted by adipose tissue and the metabolic syndrome with insulin-resistance. Obesity is associated with enhanced secretion of leptin and decreased secretion of adiponectin from adipose tissue and both increased leptin and decreased adiponectin have been shown to be independent risk factors for progression to EAC. Leptin and adiponectin have a set of mutually antagonistic actions on Barrett’s cells which appear to influence the progression of malignant behaviour. At present no drugs are of proven benefit to prevent obesity associated EAC. Roux-en-Y reconstruction is the preferred bariatric surgical option for weight loss in patients with reflux. Statins and aspirin may have chemopreventative effects and are indicated for their circulatory benefits.
