Value of scintigraphy in chronic peritoneal dialysis patients. (1/244)

BACKGROUND: A variety of factors can adversely impact chronic peritoneal dialysis (CPD) as an effective renal replacement therapy for patients with end-stage renal disease. These factors include peritonitis, poor clearances, loss of ultrafiltration, and a variety of anatomic problems, such as hernias, peritoneal fluid leaks, loculations, and catheter-related problems caused by omental blockage. This study reviews our experience with peritoneal scintigraphy for the evaluation of some of these difficulties. METHODS: From 1991 to 1996, 50 peritoneal scintigraphy scans were obtained in 48 CPD patients. Indications for scintigraphy were evaluated, and the patients were placed into four groups: group I, abdominal wall swelling; group II, inguinal or genital swelling; group III, pleural fluid; and group IV, poor drainage and/or poor ultrafiltration. A peritoneal scintigraphy protocol was established and the radiotracer isotope that was used was 2.0 mCi of 99mtechnetium sulfur colloid placed in two liters of 2.5% dextrose peritoneal dialysis solution. RESULTS: Ten scans were obtained to study abdominal wall swelling, with seven scans demonstrating leaks; six of these episodes improved with low-volume exchanges. Twenty scans were obtained to evaluate inguinal or genital swelling, and 10 of these had scintigraphic evidence for an inguinal hernia leak (9 of these were surgically corrected). One of four scans obtained to evaluate a pleural fluid collection demonstrated a peritoneal-pleural leak that corrected with a temporary discontinuation of CPD. Sixteen scans were obtained to assess poor drainage and/or ultrafiltration. Five of these scans demonstrated peritoneal location, and all of these patients required transfer to hemodialysis. The other 11 scans were normal; four patients underwent omentectomies, allowing three patients to continue with CPD. CONCLUSION: Peritoneal scintigraphy is useful in the evaluation and assessment of CPD patients who develop anatomical problems (such as anterior abdominal, pleural-peritoneal, inguinal, and genital leaks) and problems with ultrafiltration and/or drainage.  (+info)

Technical aspects of sentinel node lymphoscintigraphy for breast cancer. (2/244)

OBJECTIVE: A significant morbidity risk is associated with axillary nodal dissections for breast cancer. Many treatment decisions are based on axillary nodal status. Lymphatic mapping and sentinel node biopsy have been investigated to determine if the histology of the sentinel node reflects the remaining lymph node basin. We describe the technical aspects of sentinel node lymphoscintigraphy for breast cancer. METHODS: Ninety-three patients had lymphoscintigraphy for breast cancer. Patients with palpable lesions had 4 concentric injections around the site and lesions requiring localization had injections made through tubing connected to the localizing wire introducer needle. Immediate static images were acquired and the sentinel node was marked for surgery. Marks were reverified using a handheld gamma probe. RESULTS: Lymph nodes were visualized by lymphoscintigraphy in 87% of cases. Time to visualization of lymph nodes ranged from 1-120 min with a mean of 28 min. An average of 1.5 nodes were visualized. The overall success rate for identifying the sentinel node at time of surgery was 85%. CONCLUSION: We conclude that lymphoscintigraphy for breast cancer is a detailed procedure that requires coordination with radiology and surgery teams to ensure proper identification of sentinel lymph nodes.  (+info)

Subareolar versus peritumoral injection for location of the sentinel lymph node. (3/244)

BACKGROUND: Sentinel lymph node (SLN) biopsy is fast becoming the standard for testing lymph node involvement in many institutions. However, questions remain as to the best method of injection. The authors hypothesized that a subareolar injection of material would drain to the same lymph node as a peritumoral injection, regardless of the location of the tumor. METHODS: To test this theory, 68 patients with 69 operable invasive breast carcinomas and clinically node-negative disease were enrolled in this single-institution Institutional Review Board-approved trial. Patients were injected with 1.0 mCi of technetium-99 sulfur colloid (unfiltered) in the subareolar area of the tumor-bearing breast. Each patient received an injection of 2 to 5 cc of isosulfan blue around the tumor. Radioactive SLNs were identified using a hand-held gamma detector probe. RESULTS: The average age of patients entered into this trial was 55.2 +/- 13.4 years. The average size of the tumors was 1.48 +/- 1.0 cm. Thirty-two percent of the patients had undergone previous excisional breast biopsies. Of the 69 lesions, 62 (89.9%) had SLNs located with the blue dye and 65 (94.2%) with the technetium. In four patients, the SLN was not located with either method. All blue SLNs were also radioactive. All located SLNs were in the axilla. Of the 62 patients in which the SLNs were located with both methods, an average of 1.5 +/- 0.7 SLNs were found per patient, of which 23.2% had metastatic disease. All four patients in which no SLN was located with either method had undergone prior excisional biopsies. CONCLUSIONS: The results of this study suggest that subareolar injection of technetium is as accurate as peritumoral injection of blue dye. Central injection is easy and avoids the necessity for image-guided injection of nonpalpable breast lesions. Finally, subareolar injection of technetium avoids the problem of overlap of the radioactive zone of diffusion of the injection site with the radioactive sentinel lymph node, particularly in medial and upper outer quadrant lesions.  (+info)

99mTc-human serum albumin: an effective radiotracer for identifying sentinel lymph nodes in melanoma. (4/244)

Sentinel lymph node (SLN) biopsy has emerged as a novel approach for identifying patients with melanoma and regional nodal micrometastasis who may benefit from full nodal basin resection. To identify the pattern of tumor lymphatic drainage and the SLN, lymphoscintigraphy has been performed using primarily 99mTc-sulfur colloid (SC). In this study, we compare the efficacy of SLN biopsy using 99mTc-human serum albumin (HSA) with SLN biopsy after SC-based lymphoscintigraphy. METHODS: One hundred and six patients with localized cutaneous melanoma were studied. Lymphoscintigraphy was performed after intradermal injection of HSA in 85 patients and SC in 21 patients. Four patients underwent lymphoscintigraphy twice, once with SC and once with HSA. Dynamic images were acquired for up to 1 h, followed by high-count images of the SLN in various projections so that the most likely site was marked on the skin for biopsy. Intraoperatively, blue dye was injected around the primary site. Twenty-four patients underwent SLN dissection directed by preoperative lymphoscintigraphy and vital blue dye mapping; in the remaining 80 patients, a gamma probe was added intraoperatively to the localization procedure. Two patients underwent mapping with gamma probe alone. RESULTS: Draining lymphatic basins and nodes were identified by lymphoscintigraphy in all patients. The SLN was identified in 95% of patients when both blue dye and intraoperative gamma probe were used. When 99mTc-HSA was used for imaging, 98% of the SLNs ultimately identified were radiolabeled, and 82% were both hot and blue. Of the SLN recovered with SC, all the nodes were radiolabeled; however, there was only 58% hot and blue concordance. Greater numbers of SLNs were removed in the SC group (median 2.0 versus 1.0, P = 0.02); however, the incidence of micrometastasis was statistically similar in both HSA and SC cohorts. In the 4 patients examined with both tracers, SLN mapping was similar. CONCLUSION: Although SC has been the radiotracer of choice for SLN mapping in melanoma, HSA appears to be a suitable alternative, with identical success rates. In fact, the higher concordance between hot and blue nodes using HSA suggests superiority of this tracer for this purpose.  (+info)

The effect of dialysate dwell on gastric emptying time in patients on continuous ambulatory peritoneal dialysis. (5/244)

METHODS AND PATIENTS: We evaluated gastric emptying time (GET) with a technetium (Tc) 99m-sulfur colloid gastric emptying scan in 11 patients on continuous ambulatory peritoneal dialysis (CAPD) (6 males, 5 females) and in 14 controls. We investigated the effect of dialysate dwell on GET by studying the subjects twice: once without dialysate in the abdomen (drained) and once with 2 L of dialysate in the abdomen (full). We also investigated the relationship between body surface area (BSA) and delayed gastric emptying. RESULTS: (1) The mean gastric emptying rate in 120 minutes in patients on CAPD when drained (67.8%+/-13.4%) was not different from that in controls (65.4%+/-8.6%). (2) The mean gastric emptying rate in 120 minutes in patients on CAPD when full was significantly slower than that when drained (55.6%+/-14.6% versus 67.8%+/-13.4%, p < 0.05). In four of the 11 patients (36.4%), gastric emptying was extremely delayed from normal to abnormal range when full. (3) The BSA of patients who had extremely delayed GET from normal to abnormal range was smaller than that of patients who had minimal delayed or unchanged GET when full (1.5+/-0.11 m2 versus 1.74+/-0.22 m2). CONCLUSION: This study showed that patients on CAPD had normal gastric emptying when drained, and that gastric emptying was delayed by dialysate dwell, especially in patients who has less than 1.5 m2 of body surface area. Therefore, we suggest that, based on adequacy, intermittent nocturnal peritoneal dialysis or a small volume of dialysate be considered for patients with small body surface area.  (+info)

Validation of the lactose-[13C]ureide breath test for determination of orocecal transit time by scintigraphy. (6/244)

The breath test using oral administration of a 13C-labeled substrate, lactose-ureide (LU), to measure orocecal transit time (OCTT) was validated against 99mTc-scintigraphy. Although LU is not absorbed in the human small intestine, colonic bacteria readily metabolize LU, producing 13C-labeled CO2. The time at which 13CO2 appears in breath corresponds to the OCTT. METHODS: Twenty-two healthy volunteers ingested a meal labeled with 99mTc and 13C-LU. Scintigraphy was performed over 8 h at time intervals of 10 or 15 min. OCTT with scintigraphy was defined as the time at which at least 10% of the label had entered the colon. Breath samples were obtained every 10-15 min for 10 h and measured by isotope ratio mass spectrometry. OCTT was defined as the time of first significant increase above baseline. The results were compared using correlation and Altman-Bland statistics. RESULTS: OCTT results from scintigraphy (mean OCTT = 283+/-53 min) and breath test (mean OCTT = 292+/-58 min) correlated well (r = 0.94). Altman-Bland statistics showed close agreement between scintigraphy and breath test. No significant difference between male and female subjects was observed. CONCLUSION: The breath test using 13C-LU is a valid alternative to scintigraphy techniques for measuring OCTT.  (+info)

Scintigraphic imaging and absorption of a 5-aminosalicylic acid enema in patients with ileorectal anastomosis. (7/244)

Ileorectal anastomosis (IRA) is a possible surgical treatment for hyperacute and drug-unresponsive forms of ulcerative colitis (UC). UC relapses in the rectal remnant usually are prevented by chronic administration of 5-aminosalicylic acid (5-ASA) in topical formulations. The relationships between intestinal absorption and pattern of luminal spread of 5-ASA enemas are still unknown in patients with IRA. We correlated the absorption of a 5-ASA enema with its spread in the distal bowel of patients with IRA as assessed by 99mTc radioenema imaging. METHODS: Eight patients with UC in remission and previous IRA received a therapeutic 50-mL 5-ASA enema labeled with 99mTc-sulfer colloid. Absorbed 5-ASA and its major metabolite, acetyl 5-ASA, were measured in plasma, and dynamic images of radiolabeled enema were obtained for 6 h. The retrograde ileal spread (RIS) was determined and expressed as percentage of total enema radioactivity. Plasma levels of 5-ASA and acetyl 5-ASA were measured in six healthy volunteers after administration of the same enema volume with no radiolabeling. RESULTS: The mean 5-ASA plasma level was 0.70 microg/mL (range 0.37-0.95 microg/mL) in patients and 0.96 microg/mL (range 0.78-1.16 microg/mL) in healthy volunteers (P = not significant), and the mean acetyl 5-ASA plasma levels were 0.89 microg/mL (range 0.44-1.19 microg/mL) and 0.84 microg/mL (range 0.51-1.02 microg/mL), respectively (P = not significant). Radioenema imaging allows RIS assessment of patients with IRA. The mean value was 8.5% (range 2%-19.3%) of administered radioactivity, which correlated significantly with the total absorption of 5-ASA in the IRA group (P = 0.033, linear correlation test). Rectal wall contractions recognized by dynamic radioenema imaging were defined as a common cause of RIS episodes. CONCLUSION: In IRA patients, 5-ASA plasma levels were similar to those in healthy volunteers after administration in enema. Only part of a 50-mL 5-ASA enema reaches the ileum, and radiolabeled imaging shows the degree and number of these RIS episodes. The absorption of 5-ASA can increase in patients compared with healthy volunteers, in the presence of either occasional but significant ileal spread associated with postural factors and abdominal wall contraction or multiple moderate episodes of radioenema backdiffusion related to rectal wall motility.  (+info)

A novel, simple method of functional spleen volume calculation by liver-spleen scan. (8/244)

Spleen enlargement is commonly associated with portal hypertension from cirrhosis and may cause thrombocytopenia. Thus, accurate assessment of spleen size may be helpful in the clinical evaluation. Spleen length is not a precise estimate of spleen size because of the variation in spleen configuration, and spleen volumes measured by edging techniques can be tedious. We present a new method of measuring the functional spleen volume by liver-spleen scan (LSSs), validation experiments and some clinical data. METHODS: The method involves measurement of the total spleen counts by SPECT and dividing by a representative voxel concentration on a single frame to obtain the organ volume. Validation included phantom studies and clinical evaluation in 443 consecutive patients, including 216 with histologic assessments of chronic liver disease (CLD) and 11 healthy volunteers. RESULTS: A calibration factor determined from phantoms was used to convert the calculated volume (CV) to the "true" volume (V): V = CV (0.956) - 66.5 (r = 0.9991; P < 0.001). The volume calculations were validated in a second group of phantoms (r= 0.981; P < 0.0001). Spleen volumes were expressed as volume (cm3) and as volume per pound ideal body weight (IBW) (cm3/lb) (the conversion factor to convert cm3/lb IBW to cm3/kg IBW is 2.2). Clinical studies of reproducibility included demonstration of a significant (P < 0.0001) linear correlation between volumes calculated from repeat LSSs within 9 mo of the initial LSS in 11 healthy volunteers and 32 patients with CLD: y = 1.02x - 25; r = 0.968. The correlation with spleen volumes from autopsy or splenectomy was significant: y = 0.766x + 57; r = 0.845; P < 0.001. The normal spleen volume in 11 patients was 201 +/- 77 cm3 and 1.43 +/- 0.68 cm3/lb IBW (upper limits of normal: 335 cm3 or 2.5 cm3/lb IBW). In 443 consecutive LSSs over 15 mo, half of the patients had spleen volumes above the upper limits of healthy volunteers, and CLD was present in 90.9% of these patients. In 216 patients with histologically proven liver disease, a progressive increase in the percentage of spleen volumes above the upper limits of normal was noted from no fibrosis (10%) to mild to moderate fibrosis (36.7%) to early cirrhosis (52%) to advanced liver disease (75%). The correlation of spleen volume with platelet count was excellent (r = 0.7635; P < 0.005). CONCLUSION: This novel spleen volume measurement detects serious liver disease and correlates with splenic hyperfunction.  (+info)

UNLABELLED:Delayed gastric emptying after esophagogastrectomy can pose a significant early postoperative problem. Because erythromycin, which stimulates the gastric antral and duodenal motilin receptor, has been shown to significantly increase gastric emptying in patients with diabetic gastroparesis, we decided to evaluate its effect on gastric emptying after esophagogastrectomy. METHODS:Twenty-four patients (18 men and six women, age range 41 to 79 years, median 66 years) were randomized to receive either erythromycin lactobionate (200 mg in 50 ml normal saline solution intravenously) (n = 13) or placebo (50 ml normal saline solution intravenously (n = 11) 11 days after esophagogastrectomy (with pyloric drainage procedure). After erythromycin or placebo had been infused over a 15-minute period, patients ingested a solid meal (scrambled egg with bread) labeled with technetium 99m sulfur colloid (500 microCi) over approximately 15 minutes. Dynamic images of the stomach were then acquired over 90 ...

TY - JOUR. T1 - Lymphatic mapping for male breast cancer. AU - Albo, Daniel. AU - Ames, F. C.. AU - Hunt, K. K.. AU - Ross, M. I.. AU - Singletary, S. E.. AU - Kuerer, H. M.. PY - 2001/12/1. Y1 - 2001/12/1. N2 - OBJECTIVE: Sentinel lymph node biopsy (SLNB) is emerging as an alternative to axillary lymph node dissection (ALND) for many female breast cancer patients. In contrast, ALND remains the standard of care tor male breast patients with similar tumors. We evaluated the results of SLNB in male breast cancer patients with clinically negative axillas. METHODS: The patient population consisted of six consecutive male breast cancer patients, ages 44 to 76 years old, treated at our institution. All patients had negative axillas by clinical exam and ultrasound. Preoperative lymphoscintigraphy was used in all cases. In each patient, 5 cc of isosulfan blue 1% was injected intraoperatively adjacent to the breast tumor or biopsy cavity prior to SLNB. Additionally, Tc-99m sulfur colloid was injected at ...
Penicillin should be used with caution in individuals with histories of significant allergies and/or asthma.. Intramuscular therapy: Care should be taken to avoid intravenous administration, accidental intraarterial administration, or injection into or near major peripheral nerves or blood vessels, since many injections may produce neurovascular damage.. As with all intramuscular preparations, penicillin G benzathine should be injected well within the body of a relatively large muscle.. ADULTS: The preferred site is the upper outer quadrant of the buttock (i.e., gluteus maximus), or the mid-lateral thigh.. CHILDREN: It is recommended that intramuscular injections be given preferably in the mid-lateral muscles of the thigh. In infants and small children the periphery of the upper outer quadrant of the gluteal region should be used only when necessary, such as in burn patients, in order to minimize the possibility of damage to the sciatic nerve.. The deltoid area should be used only if well ...
TY - JOUR. T1 - Bakers cyst radionuclide arthrographic findings. AU - Lamki, L.. PY - 1985. Y1 - 1985. N2 - Radionuclide arthrography of the knee is described using Tc-99m sulfur colloid, which is injected into the synovial cavity following partial distension of the joint space with saline. The preliminary findings in Bakers cyst are described. There appear to be four patterns: 1) a herniation or cyst that can be posterior, inferior, medial or lateral to the knee synovial space; 2) a limited leak inferiorly towards the calf or superiorly toward the thigh; 3) extensive leak: giant cyst found in patients with rheumatoid arthritis; 4) multiple cysts or communications with the knee synovial space. The series is small, and more work is needed before these preliminary findings can be used as firm categories. Radionuclide arthrography should be considered in patients with unexplained calf pain or pain behind the knee, especially with a history of previous internal knee derangement, or rheumatoid ...
1. Iodination techniques, e.g., chloramine T, Bolton and Hunter. 2. Tritiation and C-14 reactions. 3. Tc-99m reactions by the Stannous Reduction Method result in chelate formation. Most Tc-99m complexes have octahedral structures and are hexa-coordinated. Example:. Sn2+ - 2e- Sn4+. _ TcO4 + 8H+ + 3 e- Tc 4+ + 4H2O. OVERALL,. _ 2Tc7+O4 + 16H+ + 3Sn2+ 2Tc4+ +3Sn4+ +8H2O. 4. Tc-99m reactions by the Thiol Reduction Method result in complex formation. In this reaction, two thiol groups (-SH) lose their H-atoms and link together to form a disulfide bridge, comparable to the cystine/cysteine reactions.. 5. Biological synthesis, e.g., Co*Cl2 in presence of streptomyces griseus produces Co* vitamin B12; yeast growing in a medium high in Se-75 and low in sulfur produces Se-75 selenomethionine.. Preparation of Radiopharmaceuticals. I. Pertechnetate: used as is after elution from the Mo/Tc Generator. II. Tc-99m sulfur colloid. A.

AU - Shereef, Serene. PY - 2014/2/1. Y1 - 2014/2/1. N2 - OBJECTIVE. The purpose of this article is to show radiologists how to readily recognize nonpuerperal subareolar abscess and its complications in order to help reduce the time to definitive therapy and improve patient care. To achieve this purpose, the various theories of pathogenesis and the associated histopathologic features are reviewed; the typical clinical characteristics are detailed in contrast to those seen in lactational abscess and inflammatory breast cancer; the common imaging findings are described with emphasis on the sonographic features; correlative pathologic findings are presented to reinforce the imaging findings as they pertain to disease origins; and the various treatment options are reviewed. CONCLUSION. Nonpuerperal subareolar mastitis ...

We theoretically investigate topological constraints and the defect structure around a spherical body immersed in a uniform nematic liquid crystal. Depending on the strength of anchoring on the particle surface, there are three possibilities. At rigid anchoring WR/K ,, 1, the inner surface constraint forces a disclination ring of a radius at approximately 1.2*R, with R the particle size. At a lower, critical value W* the disclination rings contracts to the surface and, for small anchoring, WR/K ,, 1, the director distribution is regular, defect-free ...
I am a surgical oncologist whose primary area of clinical and research interest is melanoma. In 1991, I introduced lymph-node mapping and sentinel lymph-node biopsy for melanoma and other selected skin cancers. Together, these procedures can determine during surgery whether a tumor has spread to surrounding lymph nodes. Using lymph node mapping, we can pinpoint the precise lymph node into which a nearby tumor is likely to travel first (called the sentinel node). If a biopsy of the sentinel node indicates cancer spread, the surrounding lymph nodes are removed. But if there is no evidence of cancer in the sentinel node, patients are spared from additional lymph node surgery.

Associate Professor Esben Thormann from DTU Chemistry arrived at the Center in June 2013 and is a fine example of the Centers multidisciplinary layout. With a background in colloid chemistry, he works with polymers and how colloid particles interact with each other and with material surfaces. I design responsive systems containing polymers that can be used to control drug delivery. It is not classical cancer-cure research, but it might be a very powerful tool in the battle against tumors, he states. If I design stimuli responsive polymer particles that encapsulate a drug, and if I can get these particles to accumulate in a tumor, I can specifically target the cancer cells and minimize the side effects of traditional cancer treatment. The trick is to find a physical or chemical condition which is specific for the tumor and then design the drug carrier to respond to this condition - this can be local variations in temperature, pH, ion composition or high concentration of specific enzymes, ...

Note the different intensities allow for one to visualize the bone marrow. This examination is seldom done in the 1990(s); other imaging modalities offer better anatomic resolution. Occasionally, a liver-spleen scintigraphy is ordered to assess spleen size, assess for splenic infarct, or to evaluate for degree of colloid shift to bone marrow and spleen as evidence of liver dysfunction. It may also be used to assess for accessory splenic tissue, although a heat-damaged red blood cell scan may be superior for this purpose ...
