PURPOSE: We compared the reproducibility of 201Tl and 99mTc-sestamibi (MIBI) gated SPECT measurement of myocardial function using the Germano algorithm. MATERIALS AND METHODS: Gated SPECT acquisition was repeated in the same position in 30 patients who received 201Tl and in 26 who received 99mTc-MIBI. The quantification of end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF) on 201Tl and 99mTc-MIBI gated SPECT was processed independently using Cedars quantitative gated SPECT software. The reproducibility of the assessment of myocardial function on 201Tl gated SPECT was compared with that of 99mTc-MIBI gated SPECT. RESULTS: Correlation between the two measurements for volumes and EF was excellent by the repeated gated SPECT studies of 201Tl (r=0.928 to 0.986; p<0.05) and 99mTc-MIBI (r=0.979 to 0.997; p<0.05). However, Bland Altman analysis revealed the 95% limits of agreement (2 SD) for volumes and EF were tighter by repeated 99mTc-MIBI gated SPECT (EDV: 14.1 ml, ESV: 9.4 ml and EF: 5.5%) than by repeated 201Tl gated SPECT (EDV: 24.1 ml, ESV: 18.6 ml and EF: 10.3%). The root mean square (RMS) values of the coefficient of variation (CV) for volumes and EFs were smaller by repeated 99mTc-MIBI gated SPECT (EDV: 2.1 ml, ESV: 2.7 ml and EF: 2.3%) than by repeated 201Tl gated SPECT (EDV: 3.2 ml, ESV: 3.5 ml and EF: 5.2%). CONCLUSION: 99mTc-MIBI provides more reproducible volumes and EF than 201Tl on repeated acquisition gated SPECT. 99mTc-MIBI gated SPECT is the preferable method for the clinical monitoring of myocardial function.

Uterine serosal pregnancy is an extremely rare form of ectopic pregnancy. This is a report of a 35-year-old primigravida woman who was diagnosed with uterine serosal pregnancy via laparoscopic intervention. A 35-year-old woman (gravida 1, para 0) was referred from a local clinic for a ruptured left tubal pregnancy at amenorrhea 5+0 weeks with elevated serum beta human chorionic gonadotropin (16,618 mIU/mL). A pregnancy on the left posterior wall of the uterine serosa was diagnosed during the operation and successfully treated with laparoscopic surgery as a conservative management strategy to enable fertility preservation. With the advantages of ultrasonography and laparoscopy, an early diagnosis of a primary abdominal pregnancy located on the left posterior wall of the uterine serosa was made, prior to the occurrence of severe intra-abdominal massive hemorrhage, which was then treated laparoscopically as a conservative management strategy enabling the preservation of fertility.

Clay-shoveler’s fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler’s fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2∼T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler’s fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler’s fracture is one possibility to consider.

BACKGROUND: Thoracic aortomyoplasty is one of the surgical treatment for heart failure and has advantages over artificial heart or intraaortic balloon pumps. It uses autogenous skeletal muscles and solves problems such as energy source. However its use in clinical settings has been limited. This preliminary study was designed to develop surgical technique and to determine the effect of acute descending thoracic aortomyoplsty. MATERIAL AND METHOD: Thirteen adult Mongrel dogs were used. The left latissimus dorsi muscle was wrapped around the descending aorta under general anesthesis. Swan-Ganz and microtipped Millar catheter were used for the hemodynamics and endocaridial viability ratio. Data were collected with myostimulator on and off in normal hearts and the ischemic hearts. RESULT: In normal hearts, the mean aortic diastolic pressure increased from 72+/-15mmHg at baseline to 78+/-13mmHg with stimulator on. Coronary perfusion pressure increased from 61+/-11mmHg to 65+/-9mmHg. Diastolic time increased from 0.288+/-0.003 msec to 0.290+/-0.003msec. Systolic time decreased from 0.164+/-0.002msec to 0.160+/-0.002 msec. Endocardial viability ratio increased from 1.21+/-0.22 to 1.40+/-0.18. In ischemic hearts, mean aortic diastolic pressure incrased from 56+/-21mmHg at baseline to 61+/-15mmHg with stimulator on. Coronary perfusion pressure increased from 48+/-17mmHg to 52+/-15mmHg. Diastolic time increased from 0.290+/-0.003 msec to 0.313+/-0.004msec. Systolic time decreased from 0.180+/-0.002 msec to 0.177+/-0.003 msec. Endovascular viability ratio increased from 0.9+/-0.31 to 1.1+/-0.31. The limited number of cases ruled out the statistic significance. CONCLUSIONS: Descending thoracic aortomyoplasty is a simple operation designed to use patient's own skeletal muscles. It trends to increase diastolic augmentation and coronary perfusion pressure. Modification of surgical technique and stimulator protocol would maximize the effect to assist the heart.

Anatomic variations in the biliary tree may not be detected until adulthood and they can cause unexplained jaundice and biliary pain. Recognition of these anatomic variations is important to avoid an incorrect diagnosis and significant ductal injury during biliary surgery. Although there are numerous anatomic bile duct variations, an accessory cystic duct draining into the right hepatic duct is rare. We report a case of an accessory cystic duct draining into the right hepatic duct with cholelithiasis, in which the abnormality was identified by endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography and confirmed by laparoscopic cholecystectomy.

The purpose of this study was to elucidate whether the molecular defect of acid-base transporters in renal tubules is related to the functional defect of urinary acidification in distal renal tubular acidosis(RTA). We performed NH4Cl, furosemide, or bicarbonate loading test to evaluate renal acidification function, and immunohistochemistry using antibodies to H+- ATPase, Cl-/HCO3- exchanger(band-3 protein), and Na+/K+-ATPase in kidney tissue in 6 patients with RTA and renal cell carcinoma patients as normal controls. Kidney tissue was obtained either by percutaneous needle biopsy(RTA) or nephrectomy(NC). The results were as follows; 1) In all six RTA patients, proton secretory defect of distal acidification was shown by a failure to lower the urine pH after NH4Cl loading or furosemide test or abnormally low urine-blood pCO2 difference during bicarbonate loading. In two patients with RTA, proximal acidification defect was combined, which was demonstrated by increased fractional excretion of bicarbonate. 2) In normal control, intense H+-ATPase and band-3 protein staining was observed in collecting ducts. 3) In distal RTA patients, H+-ATPase and band- 3 protein staining was not demonstrable or markedly decreased in the intercalated cells of distal nephron. 4) In two patients who had both proximal and distal RTA, H+-ATPase staining was markedly decreased in the brush border of proximal tubules as well as the distal nephron. In conclusion, the defect of acid-base transporters in renal tubule was related with the functional defect of urinary acidification in distal RTA.
