Rheolytic thrombectomy with percutaneous coronary intervention for infarct size reduction in acute myocardial infarction: 30-day results from a multicenter randomized study.

OBJECTIVES: The goal of this work was to determine whether rheolytic thrombectomy (RT) as an adjunct to primary percutaneous coronary intervention (PCI) reduces infarction size and improves myocardial perfusion during treatment of ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Primary PCI for STEMI achieves brisk epicardial flow in most patients, but myocardial perfusion often remains suboptimal. Distal embolization of thrombus during treatment may be a contributing factor. METHODS: This prospective, multicenter trial enrolled 480 patients presenting within 12 h of symptom onset and randomized to treatment with RT as an adjunct to PCI (n = 240) or to PCI alone (n = 240). Visible thrombus was not required. The primary end point was infarct size measured by sestamibi imaging at 14 to 28 days. Secondary end points included final Thrombolysis In Myocardial Infarction (TIMI) flow grade, tissue myocardial perfusion (TMP) blush, ST-segment resolution, and major adverse cardiac events (MACE), defined as the occurrence of death, new Q-wave myocardial infarction, emergent coronary artery bypass grafting, target lesion revascularization, stroke, or stent thrombosis at 30 days. RESULTS: Final infarct size was higher in the adjunct RT group compared with PCI alone (9.8 +/- 10.9% vs. 12.5 +/- 12.13%; p = 0.03). Final TIMI flow grade 3 was lower in the adjunct RT group (91.8% vs. 97.0% in the PCI alone group; p < 0.02), although fewer patients had baseline TIMI flow grade 3 in the adjunct RT group (44% vs. 63% in the PCI alone group; p < 0.05). There were no significant differences in TMP blush scores or ST-segment resolution. Thirty-day MACE was higher in the adjunct RT group (6.7% vs. 1.7% in the PCI alone group; p = 0.01), a difference primarily driven by very low mortality rate in patients treated with PCI alone (0.8% vs. 4.6% in patients treated with adjunct RT; p = 0.02). CONCLUSIONS: Despite effective thrombus removal, RT with primary PCI did not reduce infarct size or improve TIMI flow grade, TMP blush, ST-segment resolution, or 30-day MACE.

Successful reperfusion for acute ST elevation myocardial infarction is associated with a decrease in WBC count.

BACKGROUND: Elevated white blood cell (WBC) count on admission in patients with ST segment elevation myocardial infarction (STEMI) has been associated with an adverse prognosis. Whether successful reperfusion by primary percutaneous coronary intervention (PCI) is associated with a decrease in WBC count is unknown. METHODS: In this subanalysis of the On-TIME trial, WBC count was measured on admission and 6 h and 24 h after primary PCI for STEMI (n = 364). Angiographic measurements of reperfusion, including TIMI-flow and myocardial blush grade, were compared with changes in WBC count. RESULTS: Restoration of TIMI 3 flow by primary PCI was associated with a significant decrease in median WBC count (11.5 (9.7-14.2), 10.7 (9.0-12.5), 9.9 (8.5-11.5) at baseline, 6 h and 24 h), whereas after unsuccessful PCI (TIMI < 3 flow) WBC count remained elevated (12.5 (9.5-14.6), 12.1 (9.9-14.4), and 11.4 (9.2-15.2)). Improved myocardial blush was also related to a decrease in WBC count. After multivariate analysis, improved myocardial perfusion (TIMI 3 flow and myocardial blush grade 3) was an independent predictor of a decrease of WBC count after PCI. CONCLUSION: Impaired myocardial reperfusion after primary PCI for STEMI is associated with persistent WBC elevation.

Prediction of clinical outcome after mechanical revascularization in acute myocardial infarction by markers of myocardial reperfusion.

OBJECTIVES: We sought to evaluate and compare recently suggested parameters of reperfusion after angioplasty in acute myocardial infarction (AMI) for risk stratification during long-term follow-up. BACKGROUND: Abnormal myocardial perfusion has a detrimental impact on survival. Several parameters of reperfusion have been evaluated in controlled study populations for risk stratification. METHODS: In 253 consecutive patients undergoing intervention in AMI on a native coronary vessel, angiographic myocardial blush grade (MBG), corrected TIMI (thrombolysis in myocardial infarction) frame count (CTFC) and persistent ST-segment elevation (STE) were determined to evaluate reperfusion. This was a high-risk population, including referral for treatment failure at a primary center in 29.2%, failed thrombolysis in 22.1% and cardiogenic shock in 13.4% of cases. RESULTS: In addition to age, patient referral, LBBB and heart rate on admission, MBG 0 to 1 (odds ratio [OR] = 3.23, p < 0.001), CTFC (OR = 1.01, p = 0.015) and persistent STE >2 leads (OR = 3.46, p = 0.010) were univariate predictors of mortality during a 22.1 +/- 15.6 months follow-up. Myocardial blush grade 0 to 1 (OR = 2.17, p = 0.033) and persistent STE (OR = 3.61, p = 0.017) persisted as independent predictors of mortality, whereas CTFC failed. Differences in mortality between reperfusion groups at 30 days remained throughout the complete follow-up. In sequential Cox models, the predictive power of clinical data alone for mortality (model chi-squared 55.8) was strengthened by adding MBG (model chi-squared 64.2) and ECG postintervention (model chi-squared 69.2). CONCLUSIONS: Myocardial blush grade 0 to 1 and persistent STE are independent predictors for long-term mortality after angioplasty in AMI. Corrected TIMI frame count is a less powerful predictor. Combining both parameters to consider quality of reperfusion in the myocardium at risk and extent of the infarct zone increases the predictive power.

Predictive value of intraosseous venography before percutaneous vertebroplasty.

PURPOSE: Percutaneous vertebroplasty is a novel approach for treating patients with painful vertebral body compression fractures. The use of intraosseous venography before the percutaneous injection of polymethylmethacrylate (PMMA) is not universally accepted. The purpose of this study was to determine if intraosseous venography predicts PMMA flow characteristics when injected into a vertebral body. MATERIALS AND METHODS: One hundred thirty-five intraosseous venograms were obtained during 96 vertebroplasty procedures (39 thoracic, 57 lumbar) in 61 patients (49 women, 12 men; age, 36-94 y) over a 32-month period. All venograms were obtained by injecting water-soluble contrast material through the vertebroplasty needle that had been placed percutaneously via a transpedicular approach. The venograms were retrospectively reviewed by the authors and compared in a blinded fashion with the subsequent final vertebroplasty result. RESULTS: Several venographic patterns were observed: bilateral or unilateral marrow blush with or without venous filling, direct venous filling, leakage of contrast material through an endplate or cortical defect, and stasis within the marrow space. Venograms that demonstrated a bilateral marrow blush predicted flow of PMMA across the midline to adequately fill the contralateral hemivertebrae 95% of the time (40 of 42 cases). A unilateral marrow blush predicted the necessity of a second puncture 97% of the time (32 of 33 cases). Intraosseous venography predicted PMMA entering endplate/cortical defects in all cases (22 of 22) and venous structures in 29% (22 of 75) of cases. Direct venous filling was observed during two vertebroplasty procedures and gelatin foam embolization was performed before PMMA instillation. Stasis of contrast material in the marrow space was observed in 15 cases. Overall, in 83% (80 of 96) of the vertebroplasty procedures, intraosseous venography was believed to predict the flow characteristics of PMMA. CONCLUSION: Intraosseous venography provides useful information in predicting PMMA flow characteristics within the vertebral body and in predicting potential undesirable sites of cement deposition, such as through cortical defects and within venous structures.

Meningioma-associated brain oedema: the role of angiogenic factors and pial blood supply.

BACKGROUND: Approximately 60% of meningiomas are associated with perilesional brain oedema. Several aspects have been evaluated in order to understand the pathophysiological mechanisms of oedema (age, sex of the patient, size and location of the tumour, histotype, grading), although at present they have yet to be completely clarified. We focused on pial blood supply, microvascular density (MVD) and angiogenic growth factors (i.e. vascular endothelial growth factor--VEGF) in order to evaluate their putative role in the development of brain oedema. METHODS: We retrospectively studied 55 patients with intracranial meningiomas. Computerized tomography (CT) and angiographic studies were obtained in all cases. The angiograms provided an accurate differentiation between pial and dural blood supply, concomitantly with its semi-quantitative evaluation. The location and the volume of oedema, in relation to the meningioma surface, was evaluated using CT scans, as an oedema index (E/I). We also determined the expression of VEGF and MVD using standard immunohistochemical methods. RESULTS: Thirty-two out of 55 meningiomas presented peritumoural oedema, with an angiographic blush ranging from 2 to 4; VEGF protein was expressed in 27 out of 32 cases, independent of grade or histotype of tumours. In all patients, MVD ranged from 4 to 33.3 vessels (median value: 10.6). A significant relationship was found between the expression of VEGF and MVD (p = 0.0003) and between VEGF and E/I (p = 0.0023). Moreover, the E/I ratio was related to the blush (p = 0.0005). A significant association was also present between VEGF expression and pial blush (p = 0.0001). CONCLUSION: Our data confirm the central role of VEGF and pial blood supply in the pathogenesis of peritumoural oedema and support the hypothesis that the development of oedema in meningioma is vasogenic in type.

Surgical Outcomes after Preoperative Embolization of Primary and Secondary Pelvic Bone Tumors.

PURPOSE: To analyze the technical results and safety of preoperative embolization of pelvic bone tumors. MATERIALS & METHODS: Retrospective study analysis of a cohort of patients who underwent preoperative hypervascular, pelvic bone tumor embolization at the authors' institution between January 2008 and January 2025. Preinterventional data, including clinical, radiological, and laboratory findings, procedural angiographic and surgical data, and clinical follow-up data were collected from the patients' electronic medical records. Patient follow-ups were conducted until March 2025 or until the patient's death. RESULTS: Twenty-three patients (11 male patients; mean age of 42 years) underwent uneventful , preoperative embolization for primary (n=15) or metastatic (n=8) pelvic bone tumor resection. A mean of 2.3 tumor feeding arteries were preoperatively embolized with complete tumor blush disappearance in n=13 (56.5%) or near-complete tumor blush disappearance with less than 10% residual tumor blush visualized in n=10 patients (43.4%). Surgical intervention was performed with a mean of 1.7 days after embolization and was associated with a mean of 1.88 L perioperative blood loss. CONCLUSION: Preoperative pelvic tumor embolization is a safe procedure with a mean of more than two feeding arteries identified and embolized. KEY POINTS: · Preoperative embolization is a safe procedure for pelvic bone tumors.. · Angiography identified a mean of 2.3 tumor feeding arteries embolized.. · Complete preoperative angiographic tumoral devascularization was found in 56% of patients.. · Surgical intervention after preoperative tumor embolization was associated with a mean of 1.88L perioperative blood loss..

Molecular investigation of the progenitors, origin and domestication patterns of diploid Chinese old garden roses.

BACKGROUND AND AIMS: Chinese old garden roses are major contributors to the genetic development of modern roses. The RoKSN gene is associated with continuous flowering in roses and is proposed to have originated from Chinese wild roses. However, the wild roses that are implicated in the breeding of Chinese old garden roses and the origin of the RoKSN locus remain unidentified. We collected 25 of the most renowned and classic diploid Chinese old garden roses along with all related wild roses from East Asia. These roses were analysed with the aim of identifying the wild species that contributed to the genetic composition of Chinese old garden roses. In addition, we aimed to infer the geographical origin of the RoKSN gene and to develop a schematic overview of hybrid domestication of Chinese old garden roses. METHODS: We compared the haplotypes of internal transcribed spacers (nrITS), six nuclear single-copy genes and three chloroplast genes between Chinese old garden roses and wild roses. Additionally, we assessed genetic organization using 21 expressed sequence tag-simple sequence repeats to identify potential donor species that contributed to the emergence of these cultivars. Primers were designed for RoKSN to allow comparison of the gene across the entire distribution range of Rosa sect. Chinenses. KEY RESULTS: Our findings confirmed that the majority of rose cultivars are descendants of early hybridization events. Rosa chinensis var. spontanea, R. odorata var. gigantea and R. multiflora var. cathayensis were the primary donors for the 25 cultivar roses. Chinese old garden roses were categorized into four groups. Ten cultivars were hybrids between R. chinensis var. spontanea and R. multiflora var. cathayensis, thereby forming the 'Old Blush' group. Five cultivars were hybrids between 'Old Blush' and the R. kwangtungensis species complex, thereby forming the 'Slater's crimson' group. Six cultivars were hybrids between 'Old Blush' and R. odorata var. gigantea, thereby forming the 'Tea Rose' group, and three cultivars were hybrids that evolved from more than three donors. Moreover, we observed relatively close genetic proximity among Chinese old garden roses with an identical RoKSN-copia gene that is responsible for continuous flowering, which indicates a single origin for this retrotransposon-containing allele. Additionally, we determined that the haplotypes of the RoKSN-copia gene predominantly occurred in the Sichuan Basin region. In contrast, R. chinensis cultivated in the Ya'an region showed no markers of hybridization and displayed a genetic composition that was close to that of the wild species R. chinensis var. spontanea. This cultivar may represent the earliest mutated individual that bears the RoKSN-copia gene and may have served as a bridge from wild species to continuous-flowering old rose cultivars. CONCLUSIONS: The study provides crucial evidence that elucidates the origin of cultivated roses and lays the groundwork for further analysis of the breeding history of Chinese old garden roses using genomic data.

Significance of total and differential leucocyte count in patients with acute myocardial infarction treated with primary coronary angioplasty.

AIMS: The aim of this study was to correlate total and differential leucocyte (WBC) count with myocardial blush, peak CK levels, and left ventricular (LV) functional recovery at 6 months in 238 consecutive acute myocardial infarction (MI) patients treated with successful primary coronary angioplasty (PCI). METHODS AND RESULTS: Total and differential WBC counts were measured on admission and every 24 h for at least 4 days after PCI. ST-segment resolution and myocardial blush were evaluated immediately after successful primary PCI. LV functional recovery (defined as improvement involving at least two segments, or at least one segment, when only two were asynergic on the basal examination) was obtained through echocardiographic evaluation of LV wall motion at the baseline and at 6 months. Basal CK (P<0.001) and increased neutrophil levels (P<0.001) were the only independent factors related to peak CK, whereas neutrophils and monocytes peaks were related to ST-segment resolution as well as to myocardial blush grade (MBG) 2-3. MBG 2-3 and monocytes number (both as continuous values as well as percentile values) were the only variables independently associated with 6-month LV functional recovery. CONCLUSION: The present study shows that neutrophils and monocytes counts on the first days after acute MI treated with primary PCI are related to markers of effective myocardial reperfusion such as MBG 2-3 and ST-segment resolution. However, only monocytes and MBG are significantly and independently associated with contractile recovery of the infarcted area at 6 months.

Correlation between angiographic features and pathologic changes in breast carcinoma.

The correlation between angiographic tumor blushing and underlying pathologic factors was studied. Twenty female patients with breast cancer were divided into three groups according to the degree of tumor blushing. Primary tumors were divided into three areas: marginal, central and intermediate areas. In each area, the number of blood vessels per 10(4) mu 2 was randomly counted in 10 fields and a mean value of vessels was compared among the three groups. It was found that the following pathologic findings were significantly related to strong angiographic staining: (i) well-circumscribed border; (ii) large tumor nest; (iii) severe inflammatory cell infiltration; (iv) mild stromal fibrosis; and (v) absence of lymph node metastasis. The mean value of blood vessels in the strongly positive group was significantly increased in the overall and the intermediate areas. The density of the vessels in the intermediate area was thus thought to be responsible for the tumor blushing.

Quarantine strategies for olive fruit fly (Diptera: Tephritidae): low-temperature storage, brine, and host relations.

A dose-response relationship was not observed in olive fruit fly, Bactrocera oleae (Gmelin), larvae exposed to acetic acid concentrations (0-2.5%) used in commercial brine solutions to cure olives. Immersion in a 1% acetic acid brine solution impeded emergence of the immature stages. A 1-wk exposure of olives infested with olive fruit fly larvae to low-temperature storage as a postharvest treatment at 0-1 degree C resulted in 8% survival of the population, and exposures of 2 through 5 wk further reduced pupal and adult emergence to <1.0%. One- to 2-wk exposures at 2-3 degrees C resulted in a significant decrease in survival from 20 to 3%, respectively, and longer durations of 3-5 wk reduced survival to <1.0%. Mean daily fruit pulp temperatures in olives in the top, middle, and bottom of plastic bins stored at 2-3 degrees C decreased by 5-8 degrees C from the first to the second day. Lowest temperatures were observed in the top, and highest temperatures were observed in the middle layer of fruit, which attained a mean temperature of 3.8 degrees C on day 5. Laboratory choice tests showed that olive fruit fly oviposited at a higher rate in late season Mission olives that were green than in fruit that were in the red blush maturity stage in tests with 1- and 3-4-d exposure periods, and an increase in duration of exposure was related to an increase in the total number of ovipositional sites. Higher percentages of olive fruit fly third instars, pupae, and adults were reared from green fruit than from fruit in the red blush stage after a 1-d exposure to oviposition. Manzanillo olives were more attractive for oviposition by olive fruit fly than Mission olives, and significantly more third instars, pupae, and adults developed in Manzanillo fruit than in Mission fruit in the red blush stage. These differences were related to the better quality and higher flesh content of the Manzanillo versus Mission olives used in the tests.

Prediction of effectiveness of shunting in patients with normal pressure hydrocephalus by cerebral blood flow measurement and computed tomography cisternography.

Measurement of cerebral blood flow (CBF) and computed tomography (CT) cisternography were performed in 37 patients with a tentative diagnosis of normal pressure hydrocephalus (NPH) to predict their surgical outcome. The mean CBF of the whole brain was measured quantitatively by single photon emission computed tomography with technetium-99m-hexamethylpropylene amine oxime before surgery. The results of CT cisternography were classified into four patterns: type I, no ventricular stasis at 24 hours; type II, no ventricular stasis with delayed clearance of cerebral blush; type III, persistent ventricular stasis with prominent cerebral blush; type IV, persistent ventricular stasis with diminished cerebral blush and/or asymmetrical filling of the sylvian fissures. The mean CBF was significantly lower than that of age-matched controls (p < 0.005). Patients with a favorable outcome had a significantly higher mean CBF than patients with an unfavorable outcome (p < 0.005). Patients with the type I pattern did not respond to shunting. Some patients with type II and III patterns responded to shunting but improvement was unsatisfactory. Patients with type IV pattern responded well to shunting, and those with a mean CBF of 35 ml/100 g/min or over achieved a favorable outcome. The combination of CBF measurement and CT cisternography can improve the prediction of surgical outcome in patients with suspected NPH.

Nonoperative management of traumatic splenic injuries: is there a role for proximal splenic artery embolization?

OBJECTIVE: The objective of our study was to evaluate our experience with transcatheter proximal (i.e., main) splenic artery embolization (TPSAE) in the nonsurgical management of patients with grade III-V splenic injuries, according to the American Association for the Surgery of Trauma (AAST) guidelines, and patients with splenic injuries associated with CT evidence of active contrast extravasation or blush (or cases meeting both criteria). MATERIALS AND METHODS: The records of patients with traumatic splenic injuries admitted during a 52-month period were retrospectively reviewed for patient age and sex, mechanism of injury, injury severity score (ISS), RBC transfusion requirements, AAST splenic injury CT grade, presence of active contrast extravasation or blush on CT examination, and amount of hemoperitoneum on CT examination. Demographics, CT findings, transfusion requirements, and outcome were compared using the Student's t test or chi-square test in patients undergoing standard nonoperative management and nonoperative management TPSAE-that is, TPSAE followed by nonoperative management. RESULTS: Of the 79 identified patients with splenic trauma, 67 were managed nonoperatively. Thirty-seven patients (28 men, nine women; mean age, 40 years; mean ISS, 28.8) underwent nonoperative management TPSAE and 30 patients (27 men, three women; mean age, 37 years; mean ISS, 25.1) underwent nonoperative management. Age, sex, and ISS were not significantly different between the two groups. TPSAE was always technically feasible. Splenic injuries were significantly more severe in the nonoperative management TPSAE group than in the nonoperative management group with respect to the mean splenic injury AAST CT grade (3.7 vs 2, respectively; p < 0.0001), active contrast extravasation or blush (38% [14/37] vs 3% [1/30], respectively; p = 0.0005), and hemoperitoneum grade (1.6 vs 0.8, respectively; p = 0.0006). Secondary splenectomy rate was lower in the nonoperative management TPSAE group (2.7% [1/37] vs 10% [3/30]). No procedure-related complications were encountered during early and delayed clinical follow-up. CONCLUSION: TPSAE is a feasible and safe adjunct to observation in the nonoperative management of severe traumatic splenic injuries. The secondary splenectomy rate using nonoperative management TPSAE (2.7%) is among the lowest reported despite a selection of severe injuries.

The importance of pial blood supply to the development of peritumoral brain edema in meningiomas.

In a retrospective analysis, the authors studied the pial and dural blood supplies in 74 intracranial meningiomas and quantified their associated peritumoral brain edema (PTBE). The extent and localization of pial blush in relation to the total tumor volume were determined angiographically. The amount of edema and tumor size were calculated using computerized tomography. The edema-tumor volume ratio was defined as Edema Index (EI). There were 49 meningiomas with PTBE; of those tumors, 46 were supplied by pial vessels, and three were supplied exclusively by dural vessels. Tumors without PTBE showed no pial blush. The mean EI in meningiomas with pial blush was significantly larger (EI = 3) than in meningiomas without pial supply (EI = 1.1; p < 0.0001). Meningiomas with a smaller pial supply than dural supply had a significantly smaller mean EI than tumors with a pial supply equal to or greater than the dural supply (EI = 2.9 vs. EI = 3.7; p < 0.015). In 69.9% of cases with pial blood supply, major portions of the edema were located adjacent to the tumor region supplied by pial vessels. Edema index differences among tumors of different subgroups, as defined by size or histology, were significantly related to the pial supply in each subset. Thus, pial blood supply may be associated with the development of PTBE in meningiomas.

Optimization of myocardial perfusion after primary coronary angioplasty following an acute myocardial infarction. Beyond TIMI 3 flow.

UNLABELLED: Primary angioplasty has become the preferred therapeutic modality in patients with acute myocardial infarction (AMI). Despite restoration of antegrade epicardial flow by mechanical reperfusion therapy, angiographically assessed microvascular function and myocardial reperfusion (blush) allows for the stratification of patients with epicardial TIMI 3 flow into different strata of survival. Despite this fact, the best approach to achieving good myocardial blush has not yet been established. We sought to determine the efficacy of 3 different vasodilators. METHODS: A cohort of 40 patients were referred for primary angioplasty in the setting of STEMI; their TIMI 3 flow was achieved and myocardial blush (MB) was 0-1 (no myocardial opacification) according to the vant'Hof classification. The patients were assigned to 1 of 3 investigational groups: intracoronary (IC) injection of nitroprusside, adenosine and verapamil, and were compared with the control group: IC injection of nitroglycerin, their effect on MB, the sum ST-segment resolution and the left ventricular ejection fraction (LVEF) at 30 days. RESULTS: Nitroprusside proved to have the best effect on MB (p = 0.023). This correlated with an improvement in LVEF from the baseline (p = 0.048). Also, the sum ST-segment resolution showed a trend in favor of nitroprusside, but without statistical significance. CONCLUSION: IC injection of nitroprusside was more beneficial in reaching MB grade 3 in the setting of primary angioplasty for AMI, correlating with a significant improvement in LVEF at 30 days. Also, a trend toward the best ST-segment resolution was observed in the nitroprusside-treated group.

[High flow medullary venous malformation with aneurysm on the proximal artery--a case report].

Medullary Venous Malformation with an aneurysm is uncommon and only 4 cases have been reported in previous papers. We reported a case of a medullary venous malformation (MVM) of the frontal lobe with an aneurysm on its proximal artery. A 48 year old female with numbness of right fingers visited our hospital. On the CT scan, an abnormal enhanced area was found inside the left frontal lobe. The left carotid angiography showed both of an aneurysm around A com A in early arterial phase, and "MVM with early blush" in capillary-early venous phase. MRI showed linear signal void crossing the cortex to join paraventricular low intensity area (LIA) with slight cortical atrophy on sagittal slice. The CBF study by Xe-SPECT proved a high flow lesion, with mean CBF 69 (left), 59 (right) mg/100 g brain/min, Protective operation only for aneurysm was performed. The MVM in our case was proved to be a "high flow-low resistance system" by CBF study, although MVM has been considered a "low flow system". Reviewing papers, there were 3 cases of "high flow MVMs" confirmed by the measurement of CBF, all of them were large sized (greater than 4 cm) and with early blush angiographically. We conclude that large sized MVM with early blush needs hemodynamic inspection and special care to prevent "high flow MVMs" from hemorrhage and the steal.

Incidental diagnosis of pregnancy on bone and gallium scintigraphy.

Bone and gallium scintigraphy were performed as part of the diagnostic workup of a 21-yr-old woman who presented at our institution with a history of progressively worsening low back pain over a 1-wk period of time. The angiographic phase of the bone scan demonstrated a well-defined radionuclide blush within the pelvis just cephalad to the urinary bladder with persistent hyperemia noted in the blood-pool image. We attribute these findings to a uterine blush secondary to the pronounced uterine muscular hyperplasia, hyperemia, and edema that accompany pregnancy. Gallium scintigraphy demonstrated intense bilateral breast accumulation of the imaging agent in a typical doughnut pattern which is commonly found in the prelactating and lactating breast. Also demonstrated was apparent gallium accumulation in the placenta. This case is presented to emphasize the radionuclide findings that occur during pregnancy, particularly the incidental finding of radionuclide blush during the angiographic phase of a radionuclide scintigraphy which should alert the nuclear physician to the possibility of pregnancy in a woman of childbearing age.

Is the internet the best resource for blushers?

Blushing can be a disabling condition that causes sufferers great distress. It causes patients to become socially isolated, frequently being labelled as "shy". Any referral to their condition is embarrassing; even a discussion with a health care professional requires a great deal of courage. Even then, the information from non-specialists is often inaccurate and inadequate and fails to inform patients of the possible treatment options available. In today's era the internet has become an important information medium. This information on almost any subject is widely available to the general public and can be accessed at any time. It is available to blushers and health care professionals alike. It offers a non-embarrassing method of seeking help for an embarrassing condition. It is a medium for specialists to inform sufferers incognito about such a condition. We report our experience from our website: a generalised hyperhidrosis, blushing and sympathectomy information web site (www.sympathectomy.co.uk) by analysing the number of hits and requests for information. We discuss the statistics of internet access to our website including the "hit rate" and enquiry rate. Paradoxically 75% of all enquiries have been from blushers with only 25% coming from patients with hyperhidrosis.A properly designed, accurate and dynamic web site tailored towards users' needs can be used to effectively educate an information hungry but shy group.

Somatic symptoms in social phobia: a treatment method based on rational emotive therapy and paradoxical interventions.

Social phobia is often accompanied by somatic symptoms such as trembling, blushing, and sweating. In cases where these symptoms are predominant and, rather than the social situation, represent the feared stimulus, their unpredictable occurrence may reduce the effectiveness of an otherwise successful treatment, such as exposure in vivo. In this study, a paradoxical treatment approach, combined with rational emotive therapy, is employed with three social phobic patients with fears of blushing, trembling, and sweating, respectively. Results indicate that a paradoxical treatment may be an effective strategy in reducing somatic symptoms in social phobia.
