This study compares exercise radionuclide ventriculography (RNVG) and exercise myocardial scintigraphy with 201TI (MSC) both computed trisectorially. 137 patients before and after transluminal angioplasty (TCA) were investigated. While specificity equivalent was set at 90% for both methods (10% percentile of the controls [n = 29]) overall sensitivity for RNVG was 79% (n = 86) and for MSC 78% (n = 98). Sensitivity of RNVG for lesions of the posterior wall was lower than for the anterior wall: LAD stenoses 83% (n = 46), RCA stenoses 71 % (n = 17), and LCX stenoses 63% (n = 8). Sensitivity of MSC presents only a slight difference between anterior and posterior wall lesions: LAD stenoses 78% (n = 51), RCA stenoses 73% (n = 22), RCX stenoses 100% (n = 8). Reproducibility of pathological findings before and after non-successful TCA and the determination of the stenosed vessel was slightly better with MSC than with RNVG. Functional improvement after a successful TCA is predictable by MSC, whereas RNVG documents the functional improvement.

Abstract Objective To determine whether hemorrhage and complication rates vary according location of the dominant fibroid following laparoscopic myomectomy. Background Laparoscopic myomectomy is associated with less postoperative pain, analgesic requirement, shorter hospitalization period, and less febrile complications when compared to conventional laparotomy. Despite the advantages, complications like hemorrhage, blood transfusion, bowel and urinary tract injury and conversion to laparotomy may be seen in laparoscopic myomectomy. We don’t know whether fibroid location effect these complications. Materials & Methods Women, who underwent laparoscopic myomectomy at two different tertiary academic hospitals, were analyzed retrospectively. Only women with at least one intramural fibroid (Monroe type 3, 4 or 5) were included. Patients were categorized according to localization of the dominant fibroid, i.e. anterior uterine wall, posterior uterine wall, and fundus. Change in hemoglobin levels before and after surgery, and complication rates were compared across categories. Results 219 women with mean age of 35.7 +/-6 years were included. There were 81 women with fundal fibroid, 56 with anterior wall, and 72 with posterior wall fibroid. Other 10 women with intraligamentary and isthmic fibroid were excluded. The mean fibroid diameter was 6.7 ± 2.6, 6.6 ± 2.3, and 6.7 ± 2.3 cm in the fundal, anterior and posterior groups, respectively (p=0.9). The median (25 th – 75 th percentile) changes in hemoglobin levels were 1.5 (0.8 – 2.2), 1.3 (0.6 – 2.1), and 1.3 (0.9 – 2) g/dl in fundal, anterior and posterior wall groups, respectively (p = 0.55). There were 5 (6.2%), 5 (8.9%), and 2 (2.8%) complications in fundal, anterior, and posterior wall groups, respectively (p = 0.33). Conclusion Incidence of hemorrhage or complication does not seem to vary depending on fibroid location. However, the sample size was limited, the observed values suggest that fibroid location does not affect hemorrhage and complication rates.

Background: Femoral anteversion is a major contributor to functionality of the hip joint and is implicated in many joint pathologies. Accurate determination of component version intraoperatively is a technically challenging process that relies on the visual estimation of the surgeon. The following study aimed to examine whether the walls of the femoral neck can be used as appropriate landmarks to ensure appropriate femoral prosthesis version intraoperatively. Methods: We conducted a retrospective study based on 32 patients (64 hips) admitted to our centre between July and September 2020 who had undergone a CT scan of their lower limbs. Through radiological imaging analysis, the following measurements were performed bilaterally for each patient: anterior wall version, posterior wall version, and mid-neck femoral version. Anterior and posterior wall version were compared and evaluated relative to mid-neck version, which represented the true version value. Results: Mean anterior wall anteversion was 20° (95% CI, 17.6–22.8°) and mean posterior wall anteversion was −12° (95% CI, −15 to −9.7°). The anterior walls of the femoral neck had a constant of −7 and a coefficient of 0.9 (95% CI, −9.8 to −4.2; p  < 0.0001; R2 0.77). The posterior walls of the femoral neck had a constant of 20 and a coefficient of 0.7 (95% CI, 17.8–22.5; p  < 0.0001; R2 0.60). Conclusions: Surgeons can accurately obtain femoral anteversion by subtracting 7° from the angle taken between the anterior wall and the posterior femoral condyles or by adding 20° to the angle taken between the posterior wall and the posterior femoral condyles.

AIM: We aimed to evaluate the possible effects of dissecting gastric breves (GB) during the Laparoscopic Nissen Fundoplication (LNF) on the gastric fundus and splenic circulation using dynamic Magnetic Resonance Imaging (MRI).METHODS: In total 14 patients with gastroesophageal reflux disease (GERD) that was diagnosed with esophagogastroduodenoscopy and 24 - hour PH monitorization and undergoing LNF surgery were included. All patients underwent LNF surgery between October 2006 and March 2010. All patients were evaluated regarding gastric fundus and splenic circulation one week before and 15 days after the surgery with dynamic MRI. Alteration of the signal intensity before and after surgery was used to assess gastric fundus and splenic circulation.RESULTS: We detected a significant decrease in DeMeester score before and after surgery (p < 0.001). There were no statistical differences between preoperative and postoperative dynamic MRI measurements of the spleen, anterior wall measurements, posterior wall measurements in different MRI phases (Bonferroni corrected p ˃ 0.01). Postoperative measurements of anterior and posterior gastric wall measurements were comparable (Bonferroni corrected p ˃ 0.0033).CONCLUSIONS: We did not detect any significant differences in the abovementioned tissues regarding perfusion.

A new 99mTc-labelled tracer (99mTc-Sestanriibi) was used for the first time to demonstrate the perfusion of the skeletal muscle. In 16 patients with obstructive atherosclerosis of the lower limbs the change of perfusion of thigh and lower leg was studied with SPECT before and after vascular surgery (n = 11) or percutaneous transluminal angioplasty (n = 5). Comparative results of scintigraphic measurements and clinical observations (ancle-arm pressure, treadmill test) in 10 surgical patients (14 operated legs) showed correct positive or negative results in 86% (12/14).

SummaryA new method for the assay of plasmin inhibitors in human plasma is described. The method consists of determination of the caseinolytic activity of a standard plasmin solution before and after incubation with the inhibitor, with lysine added to the mixture as a stabilizer of plasmin. Using this method, it was found that plasma contains enough inhibitors to inactivate 30 caseinolytic units of plasmin, or 10 times the normal amount of plasminogen in human plasma.

The Difference

ABSTRACT The fractional determination of 17-ketosteroids in the daily urine was performed in nine cases of hyperemesis gravidarum and in four control cases, in the first trimester of pregnancy both before and after corticotrophin administration. The excretion of total 17-KS is similar in the two groups. Only in the hyperemesis group does the excretion of total 17-KS increase significantly after corticotrophin administration. The fractional determination reveals no difference between the two groups of patients with regard to the values of the fractions U (unidentified 17-KS), A (androsterone) and Rest (11-oxygenated 17-KS). The excretion of dehydroepiandrosterone is significantly higher in the hyperemesis group than in the control group. The excretion of androstanolone seems to be lower in the hyperemesis group than in the control group, but the difference is not statistically significant. The differences in the correlation between dehydroepiandrosterone and androstanolone in the two groups is significant. The high excretion of dehydroepiandrosterone and low excretion of androstanolone in cases of hyperemesis gravidarum is a sign of adrenal dysfunction.

ABSTRACT The in vitro resin uptake of 3H-prednisolone was used for the determination of blood cortisol after addition of radioactive prednisolone followed by Amberlite CG 400 Type 1 to the test serum, and incubation of the mixture. The radioactivity of the supernatant was compared before and after the addition of the resin. The principle of this method is similar to that of the 131I-triiodothyronine resin uptake for the thyroid function test. The tests for the specificity, reproducibility and sensitivity gave satisfactory results. The mean basal value ± SD of the 3H-prednisolone resin uptake was 35.3 ± 9.2% in normal subjects, and 27.1 ± 4.8% in pregnant women. This method was valid in various adrenal function tests, i. e. the adrenal circadian rhythm, corticotrophin (ACTH) test, dexamethasone suppression test and the adrenal response to lysine-8-vasopressin. It proved to be a sensitive indicator of the adrenal function. These results suggest that this method should be useful for a routine adrenal function test.
