The purpose of this study was to assess the efficacy of laparoscopic nephrectomy for a single-system ectopic ureter draining a dysplastic kidney in children. Between February 1999 and September 2005, 16 girls with a mean age of 6.2 years (range: 2-15 years) presented with urinary incontinence accompanied by regular voiding since birth (15 patients) and vaginitis (one patient). Ultrasonography, intravenous urography and a technetium-99m dimercaptosuccinic acid ( 99m Tc-DMSA) renal scan showed the presence of only a single kidney in all cases. Computed tomography (CT) showed a dysplastic kidney definitely in nine patients, structures suspicious of dysplastic kidney in three cases, and no dysplastic kidney in four cases. Magnetic resonance imaging was carried out in the four cases with non-visualized dysplastic kidneys by CT, and showed a suspicious lesion in only one case, and no lesion in the other three patients. All patients underwent transperitoneal laparoscopic nephrectomy for a dysplastic kidney. Laparoscopy identifies all dysplastic kidneys easily, even in those cases in which dystrophic kidney could not be identified by preoperative imaging. Dysplastic kidneys and ectopic ureters were removed successfully in all 16 patients. Mean operative time was 109 min (range: 40-155 min) with little intraoperative bleeding. Mean postoperative hospital stay was 2.6 days (range: 2-4 days). No intraoperative complication was encountered, except in one single case, in which a small bowel injury occurred during open Hasson's procedure. All patients became dry soon after the operation. Laparoscopic nephrectomy for an ectopic ureter draining into a dysplastic kidney is a safe and effective method, and can be carried out successfully, despite a failure by preoperative imaging studies to localize the dysplastic kidney.

In this case report, Mayer-Rokitansky-Kuster-Hauser syndrome with pelvic ectopic kidney and a perirenal cyst with endometrial tissue inside is demonstrated. A 17 year old patient admitted with primary amenorrhea. Pubertal stages were completed. In pelvic ultrasonography; uterus could not be detected, a 6x11 cm sized cystic lesion was seen on the right adnexal area. A centrally located 5.5x9 cm sized ectopic pelvic kidney was detected. Hormones and tumor markers were normal. Laparoscopy was planned. In the laparoscopic observation, uterus and both tubes could not be detected, ovaries were normal. There was a 6x7 cm sized cyst located in the retroperitoneal area, the origin of cyst could not be identified. Laparatomy was considered, retroperitoneal space was entered, an 8x11 sized smooth contoured perirenal cyst adjacent to the pelvic kidney was detected. Cyst was extirpated. The pathology result was reported to include endometrial tissue and hemorrhage inside. (author)

To describe the radiological findings associated with ectopic ureterocele and ectopic ureter in pediatric patients. To assess the role of ultrasound (US), serial micturating cystourethrography (SM-CU) and intravenous urography (IVU) in the diagnosis of these two entities. The authors performed a retrospective study of 132 patients, 73 with ectopic ureterocele and 59 with ectopic ureter. The imaging studies used were US, SMCU, IVU and methods to determine renal function (diuretic renography and renal scintigraphy). The findings were confirmed during surgery in every case. The most common radiological findings in ectopic ureterocele were renal duplication (86,3%). vesicoureteral reflux (VUR) to the lower half of the kidney (46.6%), dilatation of the lower pole of the kidney (38.4%) and contralateral duplication (30.1%). In boys, the ectopic ureter entered via bladder neck and posterior urethra (73.7%) or into seminal vesicles (15.8%); in girls, it went to vagina (32.5%), bladder neck (30%) or urethra (22.5%). Renal duplication was associated in 64.4%, with VUR to the ectopic ureter in 21% while there was a single renal system in 35.6%, with VUR to the ectopic ureter in 57.1% and contralateral renal agenesis in 19%. Eighteen patients (13.6%) presented a single, dy plastic, nonfunctioning renal system (6 cases of ureterocele and 12 of ectopic ureter). Knowledge of the embryological development of ureteral duplication is essential for the understanding of these two entities and helps to differentiate between them, thus facilitating a sometimes complicated diagnosis. Ectopic ureters and ureteroceles accompanied by a single, dysplastic renal system are associated with a greater incidence of congenital anomalies and a higher rate of complications than the duplicate systems. A prenatal US examination enables early diagnosis. The anatomical information provided by US is, on occasion, more valuable than that resulting from IVU or SMCU, However, IVU is indispensable in girls

Ectopic intrathoracic kidney is a rare congenital anomaly, usually asymptomatic. This anomaly is sometimes associated with a diaphragmatic hernia. Few cases of this combination have been described, often in the absence of a prenatal diagnosis. We report on the case of a female newborn infant who was diagnosed with an ectopic intrathoracic right kidney and a diaphragmatic hernia upon 33 weeks of gestation. The patient underwent surgery on the first day of life and the respiratory and renal outcomes were simple. We review the literature and discuss the seemingly good prognosis of this combination.

To evaluate ultrasonography as an alternative to contrast radiographyfor diagnosis of ectopic ureter in dogs, ultrasonography of the urinary tract was performed prospectively in a series of urinary incontinent dogs anesthetized for contrast radiography, Fourteen dogs had ectopic ureter based ore surgical, necropsy or unequivocal contrast radiographic findings, There were eight females and six males of a variety of breeds; five were Labrador retrievers, Mean (range) age at the time ofdiagnosis was 1.2 (0.2-4) years for females and 3.5 (0.3-5) for males(p < 0.05). Ectopic ureters were unilateral in five dogs (2 left; 3 right) find bilateral in nine dogs. Both ultrasound images and contrastradiographs were positive for 21 (91%) ectopic ureters; the same two ectopic ureters were not defected using either modality, The termination of each of the five normal ureters was visible on ultrasound images; two (40%) were visible on radiographs, Other ultrasonographic findings included dilatation of the ectopic ureter and/or ipsilateral renal pelvis ill ten (43%) instances, evidence of pyelonephritis in two dogs(with enlargement of the contralateral kidney in one dog), and urethral diverticuli in one dog, Ultrasonography is a practical diagnostic Best for ectopic ureter in clogs. In this series these was close correlation between the ultrasonographic and contrast radiographic findings for each ectopic meter, but ultrasonography enabled more accurate determination of normal ureteral anatomy

Noonan syndrome is characterised by short stature, typical facial dysmorphology and congenital heart defects. Urogenital abnormalities are reported in 10% of the cases. We present a 14-year-old girl with characteristic features of Noonan syndrome and nephrotic-range proteinuria. She had crossed fused ectopic kidneys. Renal biopsy showed focal segmental glomerulosclerosis. Oral steroids were instituted and she responded well. The case highlights this novel renal presentation of Noonan syndrome.

Full Text Available Renal ectopia is a rare congenital anomaly. Thoracic ectopic kidney was being considered as rarest, however no case of bilateral subdiaphragmatic kidneys in omphalocele patients presented with ventral hernia has been reported yet, as per our best of knowledge. This is a report of a 5- year-old male patient who presented with ventral hernia after omphalocele. A thorough examination, laboratory, and radiological investigations including ultrasonography, plain abdominal x-ray, intravenous urogram, and computerized tomography revealed bilateral subdiaphragmatic ectopic kidneys with azygos continuation of inferior vena cava, retro-aortic left renal vein and spina bifida

Objective: To discuss the imaging findings and examination methods of ectopic uretal aperture in children. Methods: The clinical data, imaging methods and findings of 68 cases with ectopic uretal aperture were analyzed retrospectively. Results: In 44 cases ectopic uretal aperture were associated with duplex kidneys (DK), and in 24 cases ectopic uretal aperture were associated with dysplasia of kidneys. IVU could display direct or indirect signs of DK in all cases. While it could hardly display dysplastic kidney and ectopic uretal aperture. CT scans were performed in 8 patients, in which DK, dysplastic kidney and the draining ureters could be evaluated. Conclusion: Definitive diagnosis is made in most cases with the integrating the clinical information and IVU findings. However, CT scan is recommended in a few cases

Full Text Available In this case, we have presented that a patient has fankoni aplastic anemia with pancakes kidney in scintigraphy and ultrasonography. The patient is 10 years old and a girl who fanconi aplastic anemia had been diagnosed since three years. In physical examination her general status is good. There was not left hand thumb and she had double the distal phalanx in his right hand thumb in her inspection. We observed 2/6 sistolic murmur in cardiovascular system examınation. Other systems were natural. Abdominal ultrasonography was observed that both the kidney were ectopic location and fused view in the left lower quadrant. Similarly in Tc-99m DTPA and DMSA renal scintigraphy, both kidneys were fused and in the left hemipelvis. The right kidney function were significantly lower by comparison with the left kidney functions. Radiological imaging is necessary in patients with Fanconi aplastic anemia without present clinical symptoms. The renal ultrasonography is important for determining pancakes. In addition, static and dynamic renal scintigraphy plays an important role in revealing the functional status of the kidneys

Full Text Available Variations of structure and position of the kidney along with variations of renal vessels are most frequently reported. Rotational variations form a rare entity that are not cited in most embryology textbooks. During an educational cadaveric dissection of a 42-year-old male, a complex picture of bilateral anatomical variants was encountered. Malrotation of both kidneys and a left lobulated ectopic kidney along with open hilum was observed. The left kidney showed a pelvic position in front of sacral promontory with three renal arteries retaining its embryological aortoiliac branches and two renal veins draining into right common iliac vein. These variations have an embryological base. Pelvic kidney with rotational variation though comparatively rare assumes great importance in view of present-day surgical procedures like laparoscopic radical nephrectomy, percutaneous nephrectomy, and renal transplantation.

Longitudinal Assessment of Left Ventricular Mass in Autosomal Dominant Polycystic Kidney Disease

Directory of Open Access Journals (Sweden)

Taimur Dad

2018-05-01

Full Text Available Introduction: The high burden of cardiovascular morbidity and mortality in autosomal dominant polycystic kidney disease (ADPKD is related to development of hypertension and left ventricular hypertrophy. Blood pressure reduction has been shown to reduce left ventricular mass in ADPKD; however, moderators and predictors of response to lower blood pressure are unknown. Methods: This was a post hoc cohort analysis of HALT PKD study A, a randomized placebo controlled trial examining the effect of low blood pressure and single versus dual renin−angiotensin blockade in early ADPKD. Participants were hypertensive ADPKD patients 15 to 49 years of age with estimated glomerular filtration rate (eGFR > 60 ml/min per 1.73 m2 across 7 centers in the United States. Predictors included age, sex, baseline eGFR, systolic blood pressure, total kidney volume, serum potassium, and urine sodium, potassium, albumin, and aldosterone. Outcome was left ventricular mass index (LVMI measured using 1.5-T magnetic resonance imaging at months 0, 24, 48, and 60. Results: Reduction in LVMI was associated with higher baseline systolic blood pressure and larger kidney volume regardless of blood pressure control group assignment (P < 0.001 for both. Male sex and baseline eGFR were associated with a positive annual slope in LVMI (P < 0.001 and P = 0.07, respectively. Conclusion: Characteristics associated with higher risk of progression in ADPKD, including higher systolic blood pressure, larger kidney volume, and lower eGFR are associated with improvement in LVMI with intensive blood pressure control, whereas male sex is associated with a smaller slope of reduction in LVMI. Keywords: autosomal dominant polycystic kidney disease, hypertension, left ventricular hypertrophy, left ventricular mass index

Bilateral cervical ectopic thymic nodules with accessory thyroid tissue and an ectopic parathyroid in the neck region

Full Text Available Some remnants of thymic tissue may be deposited along the pathway of the descent of the neck during embryologic development of the thymus. Ectopic thymic tissue is usually deposited along the pathway from the mandibular angle to the manubrium of the sternum. Most reported cases of an ectopic thymus occurred in children, and cases are less common in adults. We report a 26-year-old woman, who was incidentally found to have 2 neck nodules on the posterior side of the bilateral upper pole of the thyroid gland while undergoing a subtotal thyroidectomy. The left-side neck nodule showed accessory thyroid follicles intermixed with ectopic thymic tissue, and the right-side neck nodule was ectopic parathyroid tissue together with ectopic thymic tissue.

2013-01-01

Full Text Available Trifid pelvis is one of the rarest congenital malformations of the upper urinary tract. Trifid pelvis in a solitary kidney is a very rare presentation. A young male adult presented to us with dysuria and white discharge per urethra since 1 year on and off. Urine examination showed few pus cells and white blood cells. Initial imaging by ultrasonography revealed a solitary right kidney. A computed tomography urogram showed a normal right kidney with a trifid pelvis and left ectopic hypoplastic kidney with focal thickening at the right posterolateral aspect of the vesicoureteric junction. Cystoscopy revealed normal anterior and posterior urethra, verumontanum extending until bladder neck, no ejaculatory duct openings noted, and right ureteric orifice placed slightly laterally, with the left ureteric orifice not visualized. Right RGP confirmed a trifid pelvis. A high index of suspicion is needed for the identification of this rare condition.

Retroperitoneal ectopic pregnancy: a case report and review of the literature.

Science.gov (United States)

Yang, Man; Cidan, Lamu; Zhang, Dan

2017-10-16

Retroperitoneal ectopic pregnancy (REP) is an extremely rare type of ectopic pregnancy, with a total of less than 20 cases reported in the English literature. However, failure to recognize REP may result in severe consequences. We report a case of 32-year-old woman with REP. She had amenorrhea, left lower abdominal pain, but no vaginal bleeding. Her urine human chorionic gonadotropin (HCG) test was positive and blood HCG level was 1880 m-international units per milliliter (mIU/mL). Transvaginal ultrasound sonography showed a left adnexal mass. Laparoscopy found an enlarged uterus, normal right uterine tube and ovary, and normal left uterine tube. The left ovary was partly covered by a blood clot, but appeared normal after removing the clot. There was a 10-mm circular peritoneal defect located lateral to the left sacrocervical ligament, anterior to the left ovarian fossa, and next to the lower edge of the left broad ligament. The patient was diagnosed of having REP with the gestational tissues covered by the peritoneum. The REP was removed by laparoscopic surgery. Bleeding was stopped by bipolar coagulation and absorbable hemostatic cellulose. The patient recovered smoothly and was discharged on the next day after surgery. Her blood HCG returned to normal range 29 days after surgery. REP is very rare, but in any suspected case of ectopic pregnancy, caution must be paid to find signs of REP when the common sites of ectopic pregnancy do not have any positive findings.

Concomitant Persistent Left Superior Vena Cava and Horseshoe Kidney

Full Text Available Persistent left superior vena cava (PLSVC and horseshoe kidney (HSK are common congenital abnormalities; however presence of both in the same person is extremely rare. A patient with hepatitis C cirrhosis awaiting transplant presented with worsening liver dysfunction, diagnosed with acute renal failure secondary to hepatorenal syndrome, and required X-ray fluoroscopy guided tunneled venous catheter placement for hemodialysis. Review of imaging studies demonstrated coexistence of PLSVC and HSK. PLSVC in adulthood is usually incidental with the most common drainage pattern being without physiologic dysfunction. Isolated horseshoe kidney is still the most common of renal fusion anomalies; however etiology of coexistent PLSVC remains unknown.

Full Text Available History of present illness: A 21-year-old female presented with sudden onset suprapubic abdominal pain associated with dysuria. The patient also experienced near syncope during bowel movements three times three days ago without falling or losing consciousness. She denied fever, nausea, and vomiting. She stated that she was five weeks pregnant by last menstrual period. She had an ultrasound a few weeks before that showed no intrauterine pregnancy, but she had not followed up for additional testing. Significant findings: The patient’s serum beta-hCG was 5,637 mIU/mL. The transvaginal ultrasound showed an empty uterus with free fluid posteriorly in the pelvis and Pouch of Douglas (00:00. A 4.5 cm heterogeneous mass was visible in the left adnexa concerning for an ectopic pregnancy (00:10. Discussion: Ectopic pregnancies are a leading cause of maternal morbidity and mortality, as well as decreased fertility.1,2 Differentiating between an ectopic pregnancy and a normal early pregnancy may be difficult, since ultrasound and quantitative beta-hCG may show inconclusive results.3,4 Patients who have used fertility treatment may further complicate the picture because they are at risk for heterotypic pregnancies.5 Ectopic pregnancies most commonly implant in the fallopian tube, but may alternatively implant in the ovary, cervix, abdomen, or uterine cornua.4 Ultrasonography may show an empty uterus, adnexal mass, pelvic free fluid, or an extra-uterine gestational sac, yolk sac, and/or embryo.6 Treatment options for ectopic pregnancy include surgery or methotrexate.2,4 Some patients may be candidates for close outpatient surveillance if the diagnosis is unclear or in very limited cases for early, non-ruptured ectopic pregnancies.2,4

Case report: study of a beagle with a malignant ectopic thyroid tumor

Brewster, R.D.; Miller, C.W.; Stephens, L.C.; Jaenke, R.S.

1981-01-01

A Segment III beagle was noted clinically to have cervical edema and muffled heart sounds. Radiographically, masses were found at the base of the heart and throughout the lung field. An electrocardiogram revealed right bundle branch blockage. An echocardiogram demonstrated thickening of the left ventricle and conduction disturbances in the heart which could not be visualized by conventional diagnostic techniques. At necropsy, a neoplasm was found at the base of the heart that had extended into the pulmonary artery, right atria-auricle, interatrial septum, dorsal interventricular septum, and between the pericardium and epicardium over the surface of the right and left ventricles. The location of the tumor masses accounted for the clinical signs and the abnormalities in the electrocardiogram and echocardiogram. Light and electron microscopic examination of the neoplasm at the base of the heart and metastatic neoplasms in the lungs, kidney, and pancreas established a diagnosis of malignant ectopic thyroid tumor

Echocardiographic examinations have revealed functional cardiac abnormalities in children with chronic kidney disease. To assess the feasibility of MRI tissue phase mapping in children and to assess regional left ventricular wall movements in children with chronic kidney disease. Twenty pediatric patients with chronic kidney disease (before or after renal transplantation) and 12 healthy controls underwent tissue phase mapping (TPM) to quantify regional left ventricular function through myocardial long (Vz) and short-axis (Vr) velocities at all 3 levels of the left ventricle. Patients and controls (age: 8 years - 20 years) were matched for age, height, weight, gender and heart rate. Patients had higher systolic blood pressure. No patient had left ventricular hypertrophy on MRI or diastolic dysfunction on echocardiography. Fifteen patients underwent tissue Doppler echocardiography, with normal z-scores for mitral early diastolic (V E ), late diastolic (V A ) and peak systolic (V S ) velocities. Throughout all left ventricular levels, peak diastolic Vz and Vr (cm/s) were reduced in patients: Vz base -10.6 ± 1.9 vs. -13.4 ± 2.0 (P < 0.0003), Vz mid -7.8 ± 1.6 vs. -11 ± 1.5 (P < 0.0001), Vz apex -3.8 ± 1.6 vs. -5.3 ± 1.6 (P = 0.01), Vr base -4.2 ± 0.8 vs. -4.9 ± 0.7 (P = 0.01), Vr mid -4.7 ± 0.7 vs. -5.4 ± 0.7 (P = 0.01), Vr apex -4.7 ± 1.4 vs. -5.6 ± 1.1 (P = 0.05). Tissue phase mapping is feasible in children and adolescents. Children with chronic kidney disease show significantly reduced peak diastolic long- and short-axis left ventricular wall velocities, reflecting impaired early diastolic filling. Thus, tissue phase mapping detects chronic kidney disease-related functional myocardial changes before overt left ventricular hypertrophy or echocardiographic diastolic dysfunction occurs. (orig.)

Transposition of teeth is a rare condition, with a prevalence of 0.3-0.4% in general population. They are more commonly observed in females, and may occur unilaterally/bilaterally with greater frequency of left side occurrence in unilateral transposition cases. A 17-year-old female patient reported with the chief complaint of unaesthetic smile. On clinical examination the patient was diagnosed with Angle's class I malocclusion with an ectopically erupted maxillary left canine labial to the left central incisor with retained deciduous canine. The treatment plan decided was to extract the retained deciduous canine, level and align the ectopic canine using an R-loop. The treatment for the patient was finished in 14 months and was retained using a fixed lingual retainer in the upper and lower arches.

Throughout all left ventricular levels, peak diastolic Vz and Vr (cm/s) were reduced in patients: Vz{sub base} -10.6 ± 1.9 vs. -13.4 ± 2.0 (P < 0.0003), Vz{sub mid} -7.8 ± 1.6 vs. -11 ± 1.5 (P < 0.0001), Vz{sub apex} -3.8 ± 1.6 vs. -5.3 ± 1.6 (P = 0.01), Vr{sub base} -4.2 ± 0.8 vs. -4.9 ± 0.7 (P = 0.01), Vr{sub mid} -4.7 ± 0.7 vs. -5.4 ± 0.7 (P = 0.01), Vr{sub apex} -4.7 ± 1.4 vs. -5.6 ± 1.1 (P = 0.05). Tissue phase mapping is feasible in children and adolescents. Children with chronic kidney disease show significantly reduced peak diastolic long- and short-axis left ventricular wall velocities, reflecting impaired early diastolic filling. Thus, tissue phase mapping detects chronic kidney disease-related functional myocardial changes before overt left ventricular hypertrophy or echocardiographic diastolic dysfunction occurs. (orig.)

We report a case of a 15-year-old girl with a midline neck mass that was first noted 2 or 3 years previously. She had been treated with levothyroxine (L-T4) for congenital hypothyroidism until 11 years of age. Ultrasonography revealed an atrophic right thyroid (1.0 × 1.6 × 2.6 cm in size) and a mass (2.3 × 1.0 × 3.5 cm in size) in the upper part of the neck. No left lobe of the thyroid was detected. On further evaluation, Tc-99m pertechnetate thyroid scintigraphy and CT showed ectopic thyroid tissue in the lingual region and infrahyoid region. Thus, she was diagnosed as having dual ectopic thyroid and thyroid hemiagenesis. The atrophic right thyroid was thought be non-functional. Treatment with L-T4 was started to reduce the size of the dual ectopic thyroid tissue. This may be the first reported case of dual ectopic thyroid associated with hemiagenesis detected only by ultrasonography. Ultrasonography can confirm the presence or absence of orthotopic thyroid tissue in patients with ectopic thyroid.The cause of congenital hypothyroidism should be examined.Clinical manifestation of ectopic thyroid may appear when the treatment with L-T4 is discontinued.Annual follow-up is needed in all children when their thyroid hormone replacement is stopped.

Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

2014-01-01

Full Text Available Introduction. In males the ectopic ureter usualy drains into the prostate (50%. During ureteric developement a thin membrane (Chawalla’s membrane separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasia associated with ipsilateral uretral ectopia mimicking prostatic abscess. Case report. A subfebrile (37.3°C, 23-year-old patient, otherwise healthy, presented with persistent ascending perineal pain non-responsive to antibiotics and analgetics. Digitorectal examination (DRE showed asymmetric prostate with a soft, tender, buldging left lobe suggestive of prostatic abscess. The diagnosis was suspected using transrectal ultrasonography (TRUS, but the picture of the anechoic tubular structure in the left lobe of the prostate with a proximal undefined extraprostatic extension and a caudal intraprostatic blind end was incoclusive for the definitive diagnosis of prostatic abscess. Magnetic resonance imaging (MRI was ordered and definitive diagnosis of renal dysplasia associated with the ipsilateral ectopic ureter filled with inflamed content mimicking prostatic abscess was made. Transurethral incision/minimal resection of the distal, blindly closed end of left ectopic ureter was done. Endoscopic surgical treatment was sufficient for relief of clinical symptoms. The patient’s recovery was uneventful. Conclusion. To the best of our knowledge, a case of renal dysplasia with the ipsilateral ectopic ureter mimicking prostate abscess has not been reported so far. Cystic pelvic malformations in males may result from too craniall sprouting of the ureteral bud, with delayed absorption and ectopic opening of the distal end of the ureter.

A Rare Case of Chronic Ectopic Pregnancy Presenting as Large Hematosalpinx

Full Text Available Ectopic pregnancy is defined as implantation and subsequent development of an embryo outside the uterine lining. It has wide range of presentation from acute hemoperitoneum to chronic ectopic pregnancy. This is an unusual case of chronic ectopic pregnancy with large hematosalpinx without classical symptoms. A 22-year-old South Indian woman reported to the outpatient clinic with irregular spotting for a duration of 2 months which was not associated with pain. There was no preceding amenorrhea and previous menstrual cycles were regular. Clinically, the patient was hemodynamically stable but severely anemic. The abdomen was soft on palpation, cervical movements were not tender, and human chorionic gonadotropin was absent in the urine. Ultrasound revealed a complex adnexal mass. Magnetic resonance imaging (MRI revealed a large hematosalpinx. Laparoscopic left salpingectomy was conducted and histopathology confirmed ectopic pregnancy. Ectopic pregnancy presents diagnostic dilemmas in the absence of classical symptoms. MRI and laparoscopy are important tools in such a diagnostic dilemma.

Giant ectopic liver, hepatocellular carcinoma and pachydermia-a rare genetic syndrome?

2011-08-01

Full Text Available Abstract Ectopic liver is a very uncommon developmental anomaly that predisposes to the development of hepatocellular carcinoma. We describe the second documented case of a hepatocellular carcinoma developing in the primary liver of a patient with a rare and uncharacterized genetic symptom complex. Also present was the largest ectopic liver ever reported, measuring 12 cm in diameter which contained a solitary focus of metastatic hepatocellular carcinoma. The primary hepatocellular carcinoma is believed to have arisen in the native liver from a hepatic adenoma that was diagnosed 15 years earlier. The patient's uncharacterised condition featured prominent thick, yellow skin over the dorsum of the fingers, and was associated with follicular hyperkeratosis, abnormal plantar creases, digital clubbing, misshaped ears, a lingua plicata and an angioleiomyolipoma of the right kidney. This unique case of hepatocellular carcinoma arising from liver cell adenoma in a patient with an uncharacterised condition featuring a large ectopic liver invites discussion of the role of local factors in carcinogenesis in the parent liver but not the ectopic liver. It also underlines the imperative ongoing need for clinical autopsies.

We report here an ectopic case of Fasciola hepatica infection confirmed by recovery of an adult worm in the mesocolon. A 56-year-old female was admitted to our hospital with discomfort and pain in the left lower quadrant of the abdomen. Abdominal CT showed 3 abscesses in the left upper quadrant, mesentery, and pelvic cavity. On surgical exploration, abscess pockets were found in the mesocolon of the sigmoid colon and transverse colon. A leaf-like worm found in the abscess pocket of the mesocolon of the left colon was diagnosed as an adult fluke of F. hepatica. Histologically, numerous eggs of F. hepatica were noted with acute and chronic granulomatous inflammations in the subserosa and pericolic adipose tissues. Conclusively, a rare case of ectopic fascioliasis has been confirmed in this study by the adult worm recovery of F. hepatica in the mesocolon.

The Association of Long-Functioning Hemodialysis Vascular Access with Prevalence of Left Ventricular Hypertrophy in Kidney Transplant Recipients

2014-01-01

Full Text Available Left ventricular hypertrophy (LVH is frequently observed in chronic dialysis patients and is also highly prevalent in kidney transplant recipients. This study evaluates the impact of long-functioning hemodialysis vascular access on LVH in single center cohort of kidney transplant recipients. 162 patients at 8.7 ± 1.8 years after kidney transplantation were enrolled. Echocardiography, carotid ultrasound, and assessment of pulse wave velocity were performed. LVH was defined based on left ventricular mass (LVM indexed for body surface area (BSA and height2.7. There were 67 patients with and 95 without patent vascular access. Both study groups were comparable with respect to gender, age, duration of dialysis therapy, and time after transplantation, kidney graft function, and cardiovascular comorbidities. Patients with patent vascular access were characterized by significantly elevated LVM and significantly greater percentage of LVH, based on LVMI/BSA (66.7 versus 48.4%, P=0.02. OR for LVH in patients with patent vascular access was 2.39 (1.19–4.76, P=0.01. Regression analyses confirmed an independent contribution of patent vascular access to higher LVM and increased prevalence of LVH. We concluded that long-lasting patent hemodialysis vascular access after kidney transplantation is associated with the increased prevalence of LVH in kidney transplant recipients.

Purpose. To determine (1) the reasons for the frequently long delay in the diagnosis of an infrasphincteric ectopic ureter in girls, and (2) what role the radiologist can play in decreasing the delay. Materials and methods. Twelve girls were referred to our hospital from June 1994 until April 1997 for evaluation of constant urinary dribbling and/or vaginal discharge. Available imaging studies, radiology reports, and clinic notes were reviewed. Results. Mean age at the time of diagnosis was 6 years 7 months (range 2 years 10 months to 11 years 11 months). Mean delay until diagnosis after presentation was 2 years 5 months. Excluding the one girl whose ectopic ureter was diagnosed while she was still in diapers, mean age at the time of the first parental ``complaint`` was 4 years 9 months. The significance of the classic history of constant urinary dribbling was not recognized by physicians in 7 girls for 4 months to 7 years 10 months after presentation. Physical exam was not meticulously performed, as the ectopic orifice was visible in 8 of 12 girls. Imaging studies were ineffectively utilized: no imaging was done (for 2 years in 2 girls), inappropriate studies were done (ultrasound and voiding cystourethrography) and were misleading, studies were called normal when they were not (ultrasound and excretory urography), or perinatal imaging led to the incorrect assumption of a congenitally absent kidney in one girl and a multicystic dysplastic kidney in another. Excretory urography (EU) was diagnostic in all 10 girls with a duplex kidney, and computed tomography (CT) was supportive in 2 with a dysplastic kidney. CT was an adjunct in 3 girls; a Tc-99m-dimercaptosuccinic acid (DMSA) scan was needed in 2. Conclusion. The classic history of constant urinary dribbling in a successfully toilet-trained girl should immediately lead to an imaging search for the portion of kidney (or entire kidney) drained by an infrasphincteric ectopic ureter. EU should usually be the first

To describe a nasolacrimal duct (NLD) obstruction secondary to an ectopic tooth in a 5-year-old male Border collie. The dog was presented with a 1-month history of mucopurulent discharge from the left eye (OS) preceded by a lifelong history of epiphora OS. Treatment with neomycin/polymyxin B/dexamethasone ophthalmic solution had not improved the clinical signs, and the NLD was not patent when irrigated by the referring veterinarian. A complete ophthalmologic examination was performed followed by dacryocystorhinography and computed tomography (CT). The ophthalmologic examination revealed marked mucopurulent discharge, mild conjunctivitis, slightly elevated STT measurements, and a negative Jones test OS. Both nasolacrimal puncta OS could be cannulated without resistance for approximately 1.5 cm. Upon irrigation, copious amounts of mucopurulent discharge were exited through the corresponding punctum, while no fluid could be detected at the nares. Dacryocystorhinography was performed. Radiographs revealed an ectopic left canine tooth within the left nasal cavity. A cystic dilation of the NLD was observed proximal to the ectopic tooth. Computed tomography was performed to determine the exact position of the tooth and possible involvement of adjacent structures; CT confirmed the previous imaging findings. Treatment with systemic antibiotics, NSAIDs, and ofloxacin ophthalmic solution led to resolution of the clinical signs within several days. Surgery was declined by the owner. This is the first case report describing a blocked NLD due to an ectopic tooth in a dog. Ectopic teeth should be included as a differential diagnosis in cases of dacryocystitis and chronic epiphora in dogs. © 2014 American College of Veterinary Ophthalmologists.

2010-01-01

Objective: To discuss the value of CT in diagnosis of abdominal ectopic pheochromocytoma. Methods: CT findings of 5 cases surgically and pathologically proved with ectopic pheochromocytoma were retrospectively analyzed. Results: Soft tissue mass with light asymmetry enhancement was found between the abdominal aorta and the inferior vena ca-va in one case. 1 case was completely cystic with light enhancement of the cystwall located in front of the left side of the abdominal aorta. 1 case of large solid mass occurred between the renal hilum and the tail of pancreas, with irregular shape, unclear boundary, central necrosis, calcification and obviously enhancement at the solid part. 2 cases showed as oval soft lump with even density, moderate strengthening located before the abdominal aorta. Paroxysmal hypertension occurred in 3 cases and didn't in 2 cases. Hypertension happened in 1 case during the operation because of stimulation. Blood pressure appeared in 1 case during and after operation. Blood and urinary catecholamine increased significantly in 4 cases. Conclusion: Ectopic pheochromocytoma mainly located surround the abdominal aorta with diverse CT performance. It is helpful for diagnosing when finding a lesion locates at the specified sites combined with typical clinical presentation. CT can not only depict small tumor, but also can show the relationship with surrounding structure, and it provides important information for the operation and prognosis. (authors)

A Retinal Detachment Case with a Delay in Diagnosis Due to Unilateral Lens Coloboma and Bilateral Ectopic Pupil

2015-12-01

Full Text Available A 29-year-old female patient was admitted with the complaint of decreased vision in the left eye for the last 9 months. The visual acuity was 0.4 in the right eye and hand movements in the left eye. Biomicroscopic examination revealed ectopic pupils in both eyes and lens coloboma in the left eye; her right lens was normal. There was total retinal detachment in the left fundus. Optic disc, macula, and peripheral retina were normal in the right eye at her fundus examination. In our case, reduction of vision in the left eye was associated with ectopic pupil at various centers and this situation has led to delay in the diagnosis. Therefore, the importance of careful retinal examination should be kept in mind in cases in which the reduction of vision does not correlate with clinical picture. (Turk J Ophthalmol 2014; 44: 75-7

Orthodontic treatment is planned on an individual, case-by-case basis after thoroughly considering the patient's overall facial and dental characteristics, the expected duration of treatment, costs, patient preferences, and the orthodontist's experience. This article reports the treatment of a patient with a maxillary premolar-molar transposition in the permanent dentition that was successfully managed with orthodontic treatment. A girl, aged 10 years 2 months, came for treatment with an ectopic maxillary left premolar. Radiographic analysis indicated a developing complete transposition of the maxillary left premolar. The patient was treated with extraction of the deciduous molar and surgical exposure and ligation of the premolar. Eruption was properly guided, and the correct order of the 2 teeth was restored in the arch. This challenging treatment approach is described in detail, including the mechanics used to align the ectopic premolar. Early treatment can, in many cases, prevent a molar-premolar transposition.

The term ectopic thyroid refers to the presence of thyroid tissue located far from its usual anatomic placement and with no vascular connection to the main gland. The presence of swelling in atypical locations is diagnostically differentiated from other pathologies like pleomorphic adenoma or carcinoma, inflammatory lesions like sialadenitis, neurogenic tumors, paraganglioma, fibrolipoma and lymphadenopaties of diverse etiologies. Here we present the case of a submandibular ectopic thyroid in a 67year old woman. She came to our attention for a left submandibular swelling. The anamnesis did not show related pathologies, as well as blood tests. Diagnostic image studies and a FNAC were performed. The mass was surgically removed and histopatology showed a follicular adenoma in the contest of the capsulated lesion. It is important to not underestimate these types of lesions and procede with hematochemical, instrumental tests and above all surgery that can eliminate any diagnostic uncertainty and on the whole be therapeutic. It should not be forgotten that ectopic thyroid tissue can be a site for adenoma or papillary carcinoma and thus any watch and wait strategy should be avoided. Copyright © 2017 The Author(s).

Virilization due to androgen-secreting neoplasms in women is a result of androgen overproduction from benign or malignant tumors that are found in the ovaries or rarely in the adrenal glands. Virilizing tumors that arise from ectopic adrenal tissue are extremely rare. We describe a very rare case of an ectopic androgen-producing adrenal tumor. Case report study. Endocrinology outpatient department of university-affiliated teaching hospital. A 45-year-old woman with symptoms of virilization of abrupt onset and rapid progression, with high serum androgen hormone levels and normal glucocorticoid secretion. Basal hormonal levels, stimulation and suppression tests, imaging techniques, and selective venous sampling. Localization and surgical removal of the source of androgen production. An ectopic mass was detected behind the left iliopsoas muscle. The patient was operated on and an oblong-shaped lesion, weighing 6 g, was removed. Histologically, the tissue was identified to be of adrenal origin. Postoperatively the androgen levels decreased to normal levels. This case illustrates difficulties in detecting and localizing the rare contingence of an ectopic adrenocortical androgen-secreting tumor.

Endoscopic Endonasal Surgery for Remission of Cushing Disease Caused by Ectopic Intracavernous Macroadenoma: Case Report and Literature Review.

Complete surgical resection of an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is the gold standard of treatment of Cushing disease. Ectopic location of these adenomas is an extremely rare condition that may compromise the diagnosis and surgical success. We present the first case of an ectopic intracavernous ACTH-secreting macroadenoma totally resected with endoscopic endonasal surgery (EES). A 36-year-old woman presented with Cushing syndrome. Increased ACTH, serum cortisol, and free urine cortisol levels were identified; however, pituitary magnetic resonance imaging failed to show a pituitary tumor; instead, a parasellar lesion in the left cavernous sinus (CS) was noticed. Inferior petrosal sinus sampling showed a significant central to peripheral and lateralized left-sided ACTH gradient. The patient underwent EES. No tumor was found in the sella; however, the left CS was widely explored and a tumor was found lateral to the paraclival segment of the carotid artery. There were no complications after EES. Pathology confirmed the diagnosis of an ACTH-secreting adenoma. During the immediate postoperative course, serum cortisol levels decreased lower than 5 μg/dL. Postoperative magnetic resonance imaging showed complete tumor resection. At 20 months follow-up, the patient remained in clinical and biochemical remission of Cushing disease. Only 12 cases of ectopic intracavernous ACTH-secreting adenomas have been reported and all were microadenomas. The presence of an ectopic ACTH-secreting macroadenoma in the CS represents a surgical challenge. EES is the ideal approach for complete resection of ectopic intracavernous adenomas, allowing for a wide exploration of the CS with no surgical complications. Copyright © 2016 Elsevier Inc.

Several measurements of normal kidney in vivo were obtained from computed tomography and were correlated with age, sex and body dimensions. Forty four males and 21 females without a history of renal disease were studied. 1. Angle between renal coronal section and body frontal (degree): The mean value (+- SD) of the angle was 44.0 +- 11.1 for right kidney and 42.3 +- 11.2 for left, with a low correlation coefficient. The angle had no significant correlation with age nor sex. 2. The largest width of kidney (cm): The mean value of the width was 4.6 +- 0.6 for male right kidney, 5.1 +- 0.6 for male left, 4.6 +- 0.7 for female right and 4.7 +- 1.0 for female left. The values correlated with age under 40 positively and over 40 negatively. 3. Renal volume (cm 3 ): Renal volume was calculated by adding together the area measurements obtained from successive 1 cm thick scans, excluding renal sinus. The mean volume was 107 +- 27 for male right kidney, 114 +- 24 for male left, 101 +- 33 for female right and 111 +- 41 for female left. The correlation coefficient of right versus left renal volume was significantly high. Total renal volume, i. e. left + right renal volume, had significant negative correlation with age over 40. 4. CT numbers of kidney: Average value of right kidney was 31.4 +- 6.0 and that of left was 30.7 +- 5.9. Though the correlation coefficient between right and left was nearly 1, no significant correlation was found with other values. (author)

Roles of Chronic Low-Grade Inflammation in the Development of Ectopic Fat Deposition

Directory of Open Access Journals (Sweden)

Lulu Liu

2014-01-01

Full Text Available Pattern of fat distribution is a major determinant for metabolic homeostasis. As a depot of energy, the storage of triglycerides in adipose tissue contributes to the normal fat distribution. Decreased capacity of fat storage in adipose tissue may result in ectopic fat deposition in nonadipose tissues such as liver, pancreas, and kidney. As a critical biomarker of metabolic complications, chronic low-grade inflammation may have the ability to affect the process of lipid accumulation and further lead to the disorder of fat distribution. In this review, we have collected the evidence linking inflammation with ectopic fat deposition to get a better understanding of the underlying mechanism, which may provide us with novel therapeutic strategies for metabolic disorders.

Full Text Available Ectopic adrenal tissue is usually found in kidney and retroperitoneum, yet other locations are considered uncommon. Spermatic cord remains one of the sites where this entity is mostly incidentally found during surgical procedure in childhood. Macroscopically, it represents as yellowish, lipomatous nodule. We present a case of ectopic adrenal tissue of spermatic cord in a 3- year- old boy, found during orchidopexy of the right testicle. Histopathological analysis of the spermatic cord nodule revealed adrenal cortical tissue composed of zona fasciculata cells. Although usually being benign and asymptomatic, cases of hyperplasia, adenoma and carcinoma arising from ectopic adrenal tissue have been reported. Therefore, removal of this tissue, when detected, is recommended.

Full Text Available Bronchopulmonary carcinoids are rare pulmonary neoplasms although they account for most cases of ectopic ACTH syndromes. When feasible, the mainstay treatment is surgical resection of the tumor. We report the case of a 52-year-old woman with signs and symptoms suggestive of hypercortisolism for 12 months, admitted to our department because of community acquired pneumonia. Blood hormone analysis showed increased levels of ACTH and urinary free cortisol and nonsuppressibility to high- and low-dose dexamethasone tests. Pituitary MRI showed no lesion and no central-to-peripheral ACTH gradient was present in bilateral inferior petrosal sinus sampling. CRH stimulation test suggested an ectopic ACTH source. Thoracic CT scan revealed a nodular region measuring 12 mm located in the inferior lingular lobule of the left superior lung with negative uptake by 18-FDG-PET scan and negative SRS. The patient was successfully treated with an atypical lung resection and histology revealed an atypical bronchial carcinoid tumor with positive ACTH immunoreactivity. This was an interesting case because the patient was admitted due to pneumonia that may have been associated with her untreated and chronic hypercortisolism and a challenging case of ectopic ACTH syndrome due to conflicting results on the diagnostic exams.

Full Text Available Abdominal trauma is responsible for most genitourinary injuries. The incidence of renal artery injury and intrathoracic kidney is quite low in patients who present with blunt trauma experiencing damage. There are four defined etiologies for intrathoracic kidney, which include real intrathoracic ectopic kidney, eventration of the diaphragm, congenital diaphragmatic herniation, and traumatic diaphragmatic rupture. The traumatic intrathoracic kidney is an extremely rare case. We presented intrathoracic kidney case after traumatic posterior diaphragmatic rupture.

The thrombotic occlusion of one renal artery may become completely asymptomatic, due to the functionality of the contralateral kidney. However, in rare circumstances, such is the case of individuals with a solitary kidney, a situation of anuria and acute renal failure may constitute the main presentation of the condition. The authors report the clinical case of a 43 year old male patient, with the previous diagnosis of an infrarenal aortic occlusion and a single left kidney, who developed a thrombotic occlusion of the renal artery, with anuria and acute renal failure. The patient underwent an emergency revascularization procedure, consisting in the implantation of a prosthetic bypass graft from the superceliac aorta to the renal artery, with immediate recovery of the diuresis and renal function. Seventeen months later as a consequence of an anastomotic hyperplasia, an occlusion of the bypass graft occurred, again with anuria and acute renal failure. The patient was reoperated on and due to the inadequacy of both saphenous veins to be used as the material of choice for the revascularization procedure, a redundant segment of the left colic artery (Riolan's arcade) was removed and used as an interposition graft, from the middle colic artery to the renal artery, followed by an immediate restoration of diuresis and renal function. The singular and recurrent character of this clinical condition and the utilization of an original, eventually unique and well succeeded revascularization procedure, prompted its presentation and divulgation.

The morphogenetic mechanisms by which developing organs become left-right asymmetric entities are unknown. To investigate this issue, we compared the roles of the left and right sides of the Xenopus embryo during the development of anatomic asymmetries in the digestive system. Although both sides contribute equivalently to each of the individual digestive organs, during the initial looping of the primitive gut tube, the left side assumes concave topologies where the right side becomes convex. Of interest, the concave surfaces of the gut tube correlate with expression of the LR gene, Pitx2, and ectopic Pitx2 mRNA induces ectopic concavities in a localized manner. A morphometric comparison of the prospective concave and convex surfaces of the gut tube reveals striking disparities in their rate of elongation but no significant differences in cell proliferation. These results provide insight into the nature of symmetry-breaking morphogenetic events during left-right asymmetric organ development. ?? 2003 Wiley-Liss, Inc.

Suspected ectopic pregnancy.

Women who present with pain and bleeding in the first trimester are at risk for ectopic pregnancy, a life-threatening condition. Conditions that predispose a woman to ectopic pregnancy are damaged fallopian tubes from prior tubal surgery or previous pelvic infection, smoking, and conception using assisted reproduction. Many women without risk factors can develop an ectopic pregnancy. A diagnostic algorithm that includes the use of transvaginal ultrasonography, human chorionic gonadotropin (hCG) concentrations, and, sometimes, uterine curettage can definitively diagnose women at risk in a timely manner. The absence of an intrauterine pregnancy above an established cut point of hCG is consistent with an abnormal pregnancy but does not distinguish a miscarriage from an ectopic pregnancy. When the initial hCG value is low, serial hCG values can be used to determine whether a gestation is potentially viable or spontaneously resolving. The minimal rise in hCG for a viable pregnancy is 53% in 2 days. The minimal decline of a spontaneous abortion is 21-35% in 2 days, depending on the initial level. A rise or fall in serial hCG values that is slower than this is suggestive of an ectopic pregnancy. Women diagnosed with an unruptured ectopic pregnancy are potential candidates for medical management with methotrexate. Intramuscular injection with methotrexate can be used to safely treat an ectopic pregnancy with success rates, tubal patency rates, and future fertility that are similar to those obtained with conservative surgery. Success rates using methotrexate are inversely rated to baseline hCG values and are higher using "multidose" compared with "single-dose" regimens. Surgical treatment may be conservative or definitive and should be attempted in most cases via laparoscopy.

Patient: Female, 58 Final Diagnosis: Nephroangiosclerosis Symptoms: Renal failure Medication: — Clinical Procedure: Resuscitation of grafts by hypothermic oxygenated perfusion Specialty: Transplantology Objective: Challenging differential diagnosis Background: The recovery of discarded human kidneys has increased in recent years and impels to use of unconventional organ preservation strategies that improve graft function. We report the first case of human kidneys histologically discarded and transplanted after hypothermic oxygenated perfusion (HOPE). Case Report: Marginal kidneys from a 78-year-old woman with brain death were declined by Italian transplant centers due to biopsy score (right kidney: 6; left kidney: 7). We recovered and preserved both kidneys through HOPE and we revaluated their use for transplantation by means of perfusion parameters. The right kidney was perfused for 1 h 20 min and the left kidney for 2 h 30 min. During organ perfusion, the renal flow increased progressively. We observed an increase of 34% for the left kidney (median flow 52 ml/min) and 50% for the right kidney (median flow 24 ml/min). Both kidneys had low perfusate’s lactate levels. We used perfusion parameters as important determinants of the organ discard. Based on our previous organ perfusion experience, the increase of renal flow and the low level of lactate following 1 h of HOPE lead us to declare both kidneys as appropriate for dual kidney transplantation (DKT). No complications were reported during the transplant and in the post-transplant hospital stay. The recipient had immediate graft function and serum creatinine value of 0.95 mg/dL at 3 months post-transplant. Conclusions: HOPE provides added information in the organ selection process and may improve graft quality of marginal kidneys. PMID:28928357

Localization of the source of cardiac ectopic activity has direct clinical benefits for determining the location of the corresponding ectopic focus. In this study, a recently developed current-density (CD)-based localization approach was experimentally evaluated in noninvasively localizing the origin of the cardiac ectopic activity from body-surface potential maps (BSPMs) in a well-controlled experimental setting. The cardiac ectopic activities were induced in four well-controlled intact pigs by single-site pacing at various sites within the left ventricle (LV). In each pacing study, the origin of the induced ectopic activity was localized by reconstructing the CD distribution on the endocardial surface of the LV from the measured BSPMs and compared with the estimated single moving dipole (SMD) solution and precise pacing site (PS). Over the 60 analyzed beats corresponding to ten pacing sites (six for each), the mean and standard deviation of the distance between the locations of maximum CD value and the corresponding PSs were 16.9 mm and 4.6 mm, respectively. In comparison, the averaged distance between the SMD locations and the corresponding PSs was slightly larger (18.4 {+-} 3.4 mm). The obtained CD distribution of activated sources extending from the stimulus site also showed high consistency with the endocardial potential maps estimated by a minimally invasive endocardial mapping system. The present experimental results suggest that the CD method is able to locate the approximate site of the origin of a cardiac ectopic activity, and that the distribution of the CD can portray the propagation of early activation of an ectopic beat.

Full Text Available Abstract Background ACTH overproduction within the pituitary gland or ectopically leads to hypercortisolism. Here, we report the first case of Cushing' syndrome caused by an ectopic ACTH-secreting neuroendocrine carcinoma of the mesentery. Moreover, diagnostic procedures and pitfalls associated with ectopic ACTH-secreting tumors are demonstrated and discussed. Case presentation A 41 year-old man presented with clinical features and biochemical tests suggestive of ectopic Cushing's syndrome. First, subtotal thyroidectomy was performed without remission of hypercortisolism, because an octreotide scan showed increased activity in the left thyroid gland and an ultrasound revealed nodules in both thyroid lobes one of which was autonomous. In addition, the patient had a 3 mm hypoenhancing lesion of the neurohypophysis and a 1 cm large adrenal tumor. Surgical removal of the pituitary lesion within the posterior lobe did not improve hypercortisolism and we continued to treat the patient with metyrapone to block cortisol production. At 18-months follow-up from initial presentation, we detected an ACTH-producing neuroendocrine carcinoma of the mesentery by using a combination of octreotide scan, computed tomography scan, and positron emission tomography. Intraoperatively, use of a gamma probe after administration of radiolabeled 111In-pentetreotide helped identify the mesenteric neuroendocrine tumor. After removal of this carcinoma, the patient improved clinically. Laboratory testing confirmed remission of hypercortisolism. An octreotide scan 7 months after surgery showed normal results. Conclusion This case underscores the diagnostic challenge in identifying an ectopic ACTH-producing tumor and the pluripotency of cells, in this case of mesenteric cells that can start producing and secreting ACTH. It thereby helps elucidate the pathogenesis of neuroendocrine tumors. This case also suggests that patients with ectopic Cushing's syndrome and an octreotide

Stereotactic ablative body radiotherapy (SABR) is an emerging treatment modality for primary renal cell carcinoma. To account for respiratory-induced target motion, an internal target volume (ITV) concept is often used in treatment planning of SABR. The purpose of this study is to assess patterns of kidney motion and investigate potential surrogates of kidney displacement with the view of ITV verification during treatment. Datasets from 71 consecutive patients with free breathing four-dimensional computed tomography (4DCT) planning scans were included in this study. The displacement of the left and right hemi-diaphragm, liver dome and abdominal wall were measured and tested for correlation with the displacement of the both kidneys and patient breathing frequency. Nine patients were excluded due to severe banding artifact. Of 62 evaluable patients, the median age was 68 years, with 41 male patients and 21 female patients. The mean (range) of the maximum, minimum and average breathing frequency throughout the 4DCTs were 20.1 (11–38), 15.1 (9–24) and 17.3 (9–27.5) breaths per minute, respectively. The mean (interquartile range) displacement of the left and right kidneys was 0.74 cm (0.45-0.98 cm) and 0.75 cm (0.49-0.97) respectively. The amplitude of liver-dome motion was correlated with right kidney displacement (r=0.52, p<0.001), but not with left kidney displacement (p=0.796). There was a statistically significant correlation between the magnitude of right kidney displacement and that of abdominal displacement (r=0.36, p=0.004), but not the left kidney (r=0.24, p=0.056). Hemi-diaphragm displacements were correlated with kidney displacements respectively, with a weaker correlation for the left kidney/left diaphragm (r=0.45, [95% CI 0.22 to 0.63], p=<0.001) than for the right kidney/right diaphragm (r=0.57, [95% CI 0.37 to 0.72], p=<0.001). For the majority of patients, maximal left and right kidney displacement is subcentimeter in magnitude. The magnitude of

Ectopic preganacies are unsuccessful pregnancies that result from implantation of fertilized ovum occurring in an aberrant area. Aside from an emergency case, the early diagnosis of ectopic pregnancy is very difficult particularly in a case with insidious onset and mild clinical manifestations. Early diagnosis not only reduces the danger, but also simplifies the management of ectopic pregnancy. Ultrasonography has been an indispensable diagnostic tool in Obstetrics and Gynecology. In the authors' experience, clinical suspected ectopic pregnancy was one of the common indications for performing ultrasonography. Since Kobayashi at al. reported the appearances of ectopic pregnancy utilizing bistable B-scan ultrasonography, the ultrasonic findings of ectopic pregnancy have been reported by many authors. But, its accuracy and reliability in the diagnosis of ectopic pregnancy are still open to controversy. The authors studied 65 cases of clinically suspected ectopic pregnancy with Picker 80 L gray scale ultrasonography from Aug. 1982 to June. 1983. There were 29 confirmed cases, of which 15 were proved to have ectopic pregnancy and 14 were proved to have diseases other than ectopic pregnancy by surgical and histopathological study or by laparoscopy and follow up study. 29 confirmed cases were reviewed. The results were as follows: 1. Among 15 ectopic pregnancies, there were 12 ampullary pregnancies, 2 isthmic pregnancies and 1 interstitial pregnancy. Among 14 cases of no ectopic pregnancy, there were 5 intrauterine pregnancies, 3 myoma uteri, 2 P.I.D., and 1 case of dermoid cyst, cystic teratoma, H-mole and tubal hematoma due to previous tuball ligation, respectively. 2. The age distribution of ectopic pregnancy was from 22 to 41 years. The common clinical manifestations of ectopic pregnancy were lower abdominal pain (73.3%), vaginal spotting or bleeding (73.3%) and amenorrhea (66.7%). 3. Positive result of urine immunologic pregnancy test was 28.6% in ectopic

It has been suggested that the left kidney is easier to transplant than the right kidney because of the longer length of the left renal vein, facilitating the formation of the venous anastomosis. There are conflicting reports of differing renal allograft outcomes based on the side of donor kidney transplanted (left or right).We sought to determine the effect of side of donor kidney on early and late allograft outcome in our renal transplant population. We performed a retrospective analysis of transplanted left-right deceased donor kidney pairs in Ireland between January 1, 1998 and December 31, 2008. We used a time to death-censored graft failure approach for long-term allograft survival and also examined serum creatinine at different time points post-transplantation. All outcomes were included from day of transplant onwards. A total of 646 transplants were performed from 323 donors. The incidence of delayed graft function was 16.1% in both groups and there was no significant difference in acute rejection episodes or serum creatinine from 1 month to 8 years post-transplantation.There were 47 death-censored allograft failures in the left-sided group compared to 57 in the right-sided group (P = 0.24). These observations show no difference in renal transplant outcome between the recipients of left- and right-sided deceased donor kidneys.

According to many experimental reports on the radiation renal injuries, the influences of irradiation were observed not only in the irradiated kidney, but also in the contralateral kidney. However, its mechanism has not yet been demonstrated clearly. In order to clarify the mechanism of development of pathophysiological changes seen on the kidney of non-irradiated side, a study was made of function and pathological condition of a remaining kidney after the enucleation of ir radiated side kidney after irradiation. Twenty-eitht rabbits were divided into 4 groups. A: 14 rabbits were irradiated on their left kidney with 60 Co- gamma ray 50 Gy doses. B: 6 rabbits were nephrectomized of their left kidney on the first day after 50 Gy irradiation. C: 4 rabbits were nephrectomized of their left kidney on the eighth day after 50 Gy irradiation. D: 4 rabbits were simple nephrectomized. The results suggest that changes on the irradiated side of kidney bring about effect to the contra-lateral kidney at an early stage after the irradiation.

The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA. Our final study group included 214 patients who underwent a thin-collimated CT angiogram (contrast agent: 300 to 350 mg/ml) on a 4- (n = 56), 16- (n = 119) and 64- (n = 39) detector-row scanner. The site of origin and distribution of bronchial arteries were analyzed on transverse CT scans, maximum intensity projections and volume-rendered images. The site of the ostium of a bronchial artery was coded as orthotopic when the artery originated from the descending aorta between the levels of the fifth and sixth thoracic vertebrae; all other bronchial arteries were considered ectopic. From the studied population, 137 (64%) patients had only orthotopic bronchial arteries, whereas 77 patients (36%) had at least one bronchial artery of ectopic origin. A total of 147 ectopic arteries were depicted, originating as common bronchial trunks (n = 23; 19%) or isolated right or left bronchial arteries (n = 101; 81%). The most frequent sites of origin of the 124 ostiums were the concavity of the aortic arch (92/124; 74%), the subclavian artery (13/124; 10.5%) and the descending aorta (10/124; 8.5%). The isolated ectopic bronchial arteries supplied the ipsilateral lung in all but three cases. Bronchial artery embolization was indicated in 26 patients. On the basis of CTA information, (1

Hyperparathyroidism is an expected metabolic consequence of chronic kidney disease (CKD). Ectopic and/or supernumerary parathyroid glands (PT) may be the cause of surgical failure in patients undergoing total parathyroidectomy (PTX). To define the locations of ectopic and supernumerary PT in patients with renal hyperparathyroidism and to correlate intraoperative findings with preoperative tests. A retrospective study was conducted with 166 patients submitted to PTX. The location of PT during surgery was recorded and classified as eutopic or ectopic. The preoperative localizations of PT found by ultrasonography (USG) and Tc99m-Sestamibi scintigraphy (MIBI) were subsequently compared with intraoperative findings. In the 166 patients studied, 664 PT were found. Five-hundred-seventy-seven (86.4%) glands were classified as eutopic and 91(13.6%) as ectopic. Eight supernumerary PT were found. The most common sites of ectopic PT were in the retroesophageal and thymic regions. Taken together, USG and MIBI did not identify 56 (61.5%) ectopic glands. MIBI was positive for 69,7% of all ectopic glands located in the mediastinal and thymic regions. The presence of ectopic and supernumerary PT in patients with renal hyperparathyroidism is significant. Although preoperative imaging tests did not locate most of ectopic glands, MIBI may be important for identifying ectopic PT in the mediastinal and thymic regions.

The management of ectopic pancreas is not well defined. This study aims to determine the prevalence of symptomatic ectopic pancreas and identify those who may benefit from treatment, with a particular focus on robotically assisted surgical management. Our institutional pathology database was queried to identify a cohort of ectopic pancreas specimens. Additional clinical data regarding clinical symptomatology, diagnostic studies, and treatment were obtained through chart review. Nineteen cases of ectopic pancreas were found incidentally during surgery for another condition or found incidentally in a pathologic specimen (65.5%). Eleven patients (37.9%) reported prior symptoms, notably abdominal pain and/or gastrointestinal bleeding. The most common locations for ectopic pancreas were the duodenum and small bowel (31% and 27.6%, respectively). Three out of 29 cases (10.3%) had no symptoms, but had evidence of preneoplastic changes on pathology, while one harbored pancreatic cancer. Over the years, treatment of ectopic pancreas has shifted from open to laparoscopic and more recently to robotic surgery. Our experience is in line with existing evidence supporting surgical treatment of symptomatic or complicated ectopic pancreas. In the current era, minimally invasive and robotic surgery can be used safely and successfully for treatment of ectopic pancreas.

Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is an uncommon disorder and comprises about 15% of all patients with Cushing's syndrome (CS. Duodenal carcinoids are rare, indolent tumors usually associated with a benign progression. We hereby report a rare case of CS resulting from ectopic ACTH secretion from a duodenal neuroendocrine tumor (NET presenting with liver metastasis. A 37-year-old female presented with abdominal discomfort and dyspepsia of 1-month duration. Ultrasound abdomen suggested a well-defined hypoechoic lesion in the left lobe of the liver, suggestive of neoplasia. On clinical examination, she had Cushingoid features and persistent hypokalemia. Midnight ACTH and cortisol levels were grossly elevated at 1027 pg/ml (n < 46 pg/ml and 87.56 μg/dl (n < 7.5 μg/ml, respectively. Both overnight and high-dose dexamethasone suppression test confirmed nonsuppressed cortisol levels - 86.04 and 84.42 μg/dl (n < 1.8 μg/ml, respectively. Magnetic resonance imaging brain showed a structurally normal pituitary gland. Computed tomography scan of the abdomen revealed hepatic lesion with bilateral adrenal enlargement. A diagnosis of ectopic ACTH-dependent CS was made. Intraoperatively, a duodenal lesion of 0.5 cm × 0.5 cm was identified alongside an 8 cm × 6 cm exophytic lesion in segment IV of the liver. Frozen section of the duodenal lesion was positive for NET. She underwent a Whipple's surgery, cholecystectomy, and left hepatic lobectomy. Postoperatively, she showed clinical and biochemical remission. Herewith, we report the third case of duodenal carcinoid tumor presenting as ectopic ACTH syndrome and the first with liver metastasis.

Robots are increasingly utilized in urology, due to their favorable performance characteristics especially in prostatectomy and pyeloplasty. However, preoperative diagnosis of urogenital congenital anomalies and preoperative planning are important aspects to be considered. The presence of ectopic pelvic kidney is a challenge for the surgeon to perform robotic-assisted radical prostatectomy (RARP) without injury to the pelvic kidney (PC) or its blood supply. We report our experience of performing RARP in a patient with a PK. (author)

Full Text Available Introduction: Ectopic pregnancy is a pregnancy with extrauterine implantation. This situation is gynecologic emergency that contributes to maternal mortality. Therefore, early recognition, based on identification of the causes of ectopic pregnancy risk factors, is needed. Methods: The design descriptive observational. The samples were pregnant women who had ectopic pregnancy at Maternity Room, Emergency Unit, Dr. Soetomo Hospital, Surabaya, from 1 July 2008 to 1 July 2010. Sampling technique was total sampling using medical records. Result: Patients with ectopic pregnancy were 99 individuals out of 2090 pregnant women who searched for treatment in Dr. Soetomo Hospital. However, only 29 patients were accompanied with traceable risk factors. Discussion:. Most ectopic pregnancies were in the age group of 26-30 years, comprising 32 patients (32.32%, then in age groups of 31–35 years as many as 25 patients (25.25%, 18 patients in age group 21–25 years (18.18%, 17 patients in age group 36–40 years (17.17%, 4 patients in age group 41 years and more (4.04%, and the least was in age group of 16–20 years with 3 patients (3.03%. A total of 12 patients with ectopic pregnancy (41.38% had experience of abortion and 6 patients (20.69% each in groups of patients with ectopic pregnancy who used family planning, in those who used family planning as well as ectopic pregnancy patients with history of surgery. There were 2 patients (6.90% of the group of patients ectopic pregnancy who had history of surgery and history of abortion. The incidence rate of ectopic pregnancy was 4.73%, mostly in the second gravidity (34.34%, whereas the nulliparous have the highest prevalence of 39.39%. Acquired risk factors, i.e. history of operations was 10.34%, patients with family planning 20.69%, patients with history of abortion 41.38%, patients with history of abortion and operation 6.90% patients with family and history of abortion was 20.69%.

Deep Venous Thrombosis of the Leg, Associated with Agenesis of the Infrarenal Inferior Vena Cava and Hypoplastic Left Kidney (KILT Syndrome in a 14-Year-Old Child

Sakshi Bami

2015-01-01

Full Text Available Agenesis of the inferior vena cava (IVC is a rare anomaly which can be identified as incidental finding or can be associated with iliofemoral vein thrombosis. IVC agenesis has a known association with renal anomalies which are mainly confined to the right kidney. We describe a case of a 14-year-old male who presented with left leg swelling and pain. Ultrasonography confirmed the presence of left leg deep vein thrombosis (DVT. No underlying hematologic risk factors were identified. A CT scan was obtained which demonstrated absent infrarenal IVC and extensive thrombosis in the left deep venous system and development of collateral venous flow into the azygous/hemiazygous system, with extension of thrombus into paraspinal collaterals. An additional finding in the patient was an atrophic left kidney and stenosis of an accessory left renal artery. Agenesis of the IVC should be considered in a young patient presenting with lower extremity DVT, especially in patients with no risk factors for thrombosis. As agenesis of the IVC cannot be corrected, one should be aware that there is a lifelong risk of lower extremity DVT.

Thyroid ectopy is characterized by the presence of thyroid tissue outside its normal position resulting from a defect of the thyroid diverticulum migration from the base of the tongue until its final pre-tracheal position. One case is presented in a 12-year-old girl patient who consults for a failure to thrive estimated at less than three standard deviations (SD). Bone age was estimated at 8 years late compared to chronological age. The hormonal assessment showed hypothyroidism with negative thyroid antibodies. Cervical ultrasound was revealed thyroid parenchyma pre-dominantly left in place while sweeping the area under chin showed a nodular formation of the base of the tongue. Thyroid scan with technetium 99 m showed a selective uptake of radiotracer in sublingual position. Cervical computed tomography revealed a posterior median sublingual mass spontaneously hyperdense and enhancing sharply after injection of contrast. Treatment with thyroxine allowed obtaining euthyroidism. This case asks us to be careful before aetiological diagnosis of hypothyroidism in children, because although this is rare, the presence of a thyroid parenchyma up to the cervical ultrasound does not eliminate the presence of ectopic tissue

Full Text Available Primary ectopic craniopharyngioma is a rare entity. Isolated petrous apex bone location has not been reported previously. This study reports a case of 26-year-old male with right abducent nerve palsy. CT and MRI imaging reveal right petrous apex cystic lesion. No sellar or suprasellar region involvement was found. Endoscopic endonasal transphenoid approach has been successfully performed. Histopathology examination confirms the diagnosis of adamantinomatous craniopharyngioma. So far, it’s probably the first case report of primary ectopic craniopharyngioma isolated in the petrous apex. This case report supports the premise that primary ectopic craniopharyngioma is a multifactorial process that starts with an error from migrated embryological cells.

Lee, Eun Byeul; Ahn, Sung Min; Lee, Wang Hui

2016-01-01

99mTc-MAG 3 Renal scan is a method that acquires dynamic renal scan image by using 99mTc-MAG 3 and dynamically visualizes process of radioactive agent being absorbed to kidney and excreted continuously. Once the test starts, ratio in both kidneys in 1-2.5 minutes was measured to obtain split renal function and split renal function can be expressed in ratio based on overall renal function. This study is based on compares split renal function obtained from data acquired from posterior detector, which is a conventional renal function test method, with split renal function acquired from the geometric mean of values obtained from anterior and posterior detectors, and studies utility of attenuation compensation depending on difference in geometric mean kidney depth. From July, 2015 to February 2016, 33 patients who undertook 99mTc-MAG 3 Renal scan(13 male, 20 female, average age of 44.66 with range of 5-70, average height of 160.40 cm, average weight of 55.40 kg) were selected as subjects. Depth of kidney was shown to be 65.82 mm at average for left and 71.62 mm at average for right. In supine position, 30 out of 33 patients showed higher ratio of deep-situated kidney and lower ratio of shallow-situated kidney. Such result is deemed to be due to correction by attenuation between deep-situated kidney and detector and in case where there is difference between the depth of both kidneys such as, lesions in or around kidney, spine malformation, and ectopic kidney, ratio of deep-situated kidney must be compensated for more accurate calculation of split renal function, when compared to the conventional test method (posterior detector counting)

Ectopic fat located in the kidney has emerged as a novel cause of obesity-related chronic kidney disease (CKD). In this study, we aimed to investigate whether inflammatory stress promotes ectopic lipid deposition in the kidney and causes renal injury in obese mice and whether the pathological process is mediated by the fatty acid translocase, CD36. High-fat diet (HFD) feeding alone resulted in obesity, hyperlipidemia, and slight renal lipid accumulation in mice, which nevertheless had normal kidney function. HFD-fed mice with chronic inflammation had severe renal steatosis and obvious glomerular and tubular damage, which was accompanied by increased CD36 expression. Interestingly, CD36 deficiency in HFD-fed mice eliminated renal lipid accumulation and pathological changes induced by chronic inflammation. In both human mesangial cells (HMCs) and human kidney 2 (HK2) cells, inflammatory stress increased the efficiency of CD36 protein incorporation into membrane lipid rafts, promoting FFA uptake and intracellular lipid accumulation. Silencing of CD36 in vitro markedly attenuated FFA uptake, lipid accumulation, and cellular stress induced by inflammatory stress. We conclude that inflammatory stress aggravates renal injury by activation of the CD36 pathway, suggesting that this mechanism may operate in obese individuals with chronic inflammation, making them prone to CKD.

Transvaginal(TV) sonography uses high-frequency transducer and allows access to the uterus and adnexa, provides better resolution and more accurate diagnosis of ectopic pregnancy. To determine the value and the utility of TV sonography for a suspected ectopic pregnancy, we studied 56 women during 4 months from January to April 1989. Of 56 patients 46 had an surgically confirmed ectopic pregnancy, 5 had not an ectopic pregnancy and 5 had not follow up. TV sonography provides definite sonographic diagnosis of ectopic pregnancy including an extrauterine gestational sac 34 cases(74%), extrauterine embryo 9 caes(19.7%), hematosalpinx 10 cases(21.7%). Overall adnexal mass was detected in 38 cases(82.6%) at initial TV sonography and in 44 cases(95.6%) at follow up TV sonography. Additional findings were uterine decidual reaction 19 cases(41.3%), pseudo G-sac 4 cases(8.7%), cul-de-sac fluid 42 cases(91.2%). Follow-up TV sonography showed newly developed or growing adnexal mass in 8 among 9 cases. False positive 5 cases were two ovarian cysts, one incomplete abortion, two parametrial thickening due to previous ectopic pregnancy and salpingectomy. TV sonography may improve the govality of patient management by early diagnosis and early surgical treatment, so may preserve fertility. In conclusion, we may suggest that TV sonography is an integral part of diagnostic modality in suspected ectopic pregnancy.

We report a case of intraorbital meningioma. Operative findings and histopathological examination revealed the tumoc to be meningothelial meningloma and to be located entirely outside the optic dura. This case demonstrates the occurrence of primary intraorbital ectopic meningioma, and the tumor was removed through a modified Dolenc approach. The primary intraorbital ectopic meningioma is discussed and the surgical approach to the orbital apex region is reviewed. ImagesFigure 1Figure 2Figure 4Figure 5 PMID:17171081

Ectopic decidua of the greater omentum: a case report

Biserka Pigac

2016-04-01

Full Text Available Ectopic decidua is defined as extrauterine deposits of decidual stromal cells. It occurs in 85-100% of pregnancies. Focal sites can be present in various locations, yet a peritoneal location is rare. A 24- year- old woman underwent a cesarean section in 39th week of her first pregnancy, during which adhesions of the omentum to the fundus, entire left side of the uterus, and a part of the right front abdominal wall were found. An operative specimen was taken for a pathohistological analysis under the assumption of being fibrous adhesive tissue. The analysis revealed ectopic decidual tissue composed of large, polygonal cells with eosinophilic cytoplasm, and large nuclei with conspicuous nucleoli infiltrated with mature fatty cells and lymphocytes. Strong staining for vimentin was observed in the decidual cell cytoplasm and for a progesterone- receptor in the cell nuclei, medium staining was detected for S-100, and negative staining for CK 5/ 6, HMB-45, desmin, smooth muscle actin, estrogen and androgen- receptors. We present this case in order to educate clinicians and pathologists about the phenomenon of ectopic deciduosis. Although it can exist as asymptomatic condition, we point out the importance of considering this condition since it can result in serious pathology, like intraperitoneal hemorrhage and labour obstruction, if remains unrecognized. Another pitfall is possible confusion of this entity with other conditions. A resemblance to adhesions of the omentum and malignant neoplastic lesions, like squamous cell and metastatic carcinoma, metastatic melanoma, malignant decidual mesothelioma, metastatic mucin -producing adenocarcinoma, can be deceiving. These obstacles may present a pitfall to clinicians and pathologists, with a negative impact on patient treatment and outcome.

BACKGROUND Adequate portal venous flow is required for successful liver transplantation. Reduced venous flow and blood flow 'steal' by collateral vessels are a concern, and when there is a prominent splenorenal shunt present, ligation of the left renal vein has been recommended to improve portal venous blood flow. CASE REPORT A 51-year-old man who had undergone right nephrectomy in childhood required liver transplantation for liver cirrhosis and hepatocellular carcinoma due to hepatitis C virus (HCV) infection. The patient had no other comorbidity and no history of hepatorenal syndrome. At transplantation surgery, portal venous flow was poor and did not improve with ligation of shunt veins, but ligation of the left renal vein improved portal venous flow. On the first and fifth postoperative days, the patient was treated with basiliximab, a chimeric monoclonal antibody to the IL-2 receptor, and methylprednisolone. The calcineurin inhibitor, tacrolimus, was introduced on the fifth postoperative day. On the sixteenth postoperative day, renal color Doppler ultrasound showed normal left renal parenchyma; hepatic Doppler ultrasound showed good portal vein flow and preserved hepatic parenchyma in the liver transplant. CONCLUSIONS This case report has shown that in a patient with a single left kidney, left renal vein ligation is feasible and safe in a patient with no other risk factors for renal impairment following liver transplantation. Modification of postoperative immunosuppression to avoid calcineurin inhibitors in the very early postoperative phase may be important in promoting good recovery of renal function and to avoid the need for postoperative renal dialysis.

The diseases ectopic kidney is a rare malformation. It can be associated with other urological or nonurological malformation. We report 11 cases observed between 1980 and 1998. They were five females and six males with a mean age of 28 years. The clinical symptomatology was dominated by pain and urinary symptoms. Diagnosis was based on the IVP data and ultrasonography. Renal stone and hynronephrosis were each associated in five cases and one patient had renal stone associated with hydronephrosis. The treatment consisted on a iliopelvic approach and extraction of the stone and or pyeloplasty. In three cases a nephrectomy was realised for muet kidney or pyonephrosis. The outcome was good in ten cases and one patient had a pyelo-ureteral secondary stenosis managed by endoscopy.

Localization of ectopic gastric mucosa by scintigraphy

International Nuclear Information System (INIS)

D'Alonzo, W.A. Jr.

1988-01-01

When gastric mucosal tissue occurs outside of the confines of the stomach, it is termed ectopic or heterotopic. Ectopic gastric mucosa may be found within Meckel's diverticulum, duplications of the alimentary tract, and Barrett's esophagus. In addition, a surgeon may inadvertently leave behind antral gastric mucosa while performing a partial gastrectomy for peptic ulcer disease (i.e., retained gastric antrum). It is important to detect the presence and location of ectopic mucosa because acid and pepsin secretion may cause ulceration in the adjacent tissue resulting in serious complications. The only currently available specific diagnostic technique for detecting ectopic gastric mucosa is pertechnetate Tc 99m (TcO 4- ) scintigraphy. This chapter reviews the functional anatomy of gastric mucosa, the mechanism of TcO 4 - localization, the various entities containing ectopic gastric mucosa, and the methods and results of TcO 4 - scanning for these disorders

99mTc-MAG{sub 3} Renal scan is a method that acquires dynamic renal scan image by using 99mTc-MAG{sub 3} and dynamically visualizes process of radioactive agent being absorbed to kidney and excreted continuously. Once the test starts, ratio in both kidneys in 1-2.5 minutes was measured to obtain split renal function and split renal function can be expressed in ratio based on overall renal function. This study is based on compares split renal function obtained from data acquired from posterior detector, which is a conventional renal function test method, with split renal function acquired from the geometric mean of values obtained from anterior and posterior detectors, and studies utility of attenuation compensation depending on difference in geometric mean kidney depth. From July, 2015 to February 2016, 33 patients who undertook 99mTc-MAG{sub 3} Renal scan(13 male, 20 female, average age of 44.66 with range of 5-70, average height of 160.40 cm, average weight of 55.40 kg) were selected as subjects. Depth of kidney was shown to be 65.82 mm at average for left and 71.62 mm at average for right. In supine position, 30 out of 33 patients showed higher ratio of deep-situated kidney and lower ratio of shallow-situated kidney. Such result is deemed to be due to correction by attenuation between deep-situated kidney and detector and in case where there is difference between the depth of both kidneys such as, lesions in or around kidney, spine malformation, and ectopic kidney, ratio of deep-situated kidney must be compensated for more accurate calculation of split renal function, when compared to the conventional test method (posterior detector counting)

Full Text Available Osaheni L Lawani, Okechukwu B Anozie, Paul O Ezeonu Department of Obstetrics and Gynecology, Federal Teaching Hospital, Abakaliki, Nigeria Background: Ectopic pregnancy is a life-threatening gynecological emergency, and a significant cause of maternal morbidity and mortality in Nigeria. Objective: The aim of this work was to determine and evaluate the incidence, clinical presentation, risk factors, and management outcomes of ectopic pregnancies at Ebonyi State University Teaching Hospital (EBSUTH in Abakaliki. Methods: This was a retrospective, descriptive study of ectopic pregnancies managed in EBSUTH during the study period (June 1, 2002 to May 31, 2012. The medical records of the patients managed for ectopic pregnancy as well as the total birth record and gynecological admission records during the period under review were retrieved, and data were collected with the aid of data-entry forms designed for this purpose. There were 4,610 gynecological admissions and 9,828 deliveries, with 215 cases of ectopic pregnancies. A total of 205 cases were suitable for analysis after excluding cases with incomplete records. The relevant data collected were analyzed with SPSS version 15.0 for Windows. Results: Ectopic pregnancy constituted 4.5% of all gynecological admissions, and its incidence was 2.1%. The mean age of the patients was 27 ± 2 years, 196 of 205 (95.6% had ruptured ectopic pregnancies, and the remaining nine (4.4% were unruptured. The commonest (166 of 205, 80.0% clinical presentation was abdominal pain, and the commonest (105 of 205, 51.2% identified risk factor was a previous history of induced abortion. Three deaths were recorded, giving a case-fatality rate of 1.4% (three of 205. Conclusion: Ectopic pregnancy is a recognized cause of maternal morbidity and mortality and has remained a reproductive health challenge to Nigerian women, as well as a threat to efforts in achieving the UN's Millennium Development Goal 5 in sub-Saharan Africa

The Flexibility of Ectopic Lipids

Full Text Available In addition to the subcutaneous and the visceral fat tissue, lipids can also be stored in non-adipose tissue such as in hepatocytes (intrahepatocellular lipids; IHCL, skeletal (intramyocellular lipids; IMCL or cardiac muscle cells (intracardiomyocellular lipids; ICCL. Ectopic lipids are flexible fuel stores that can be depleted by physical exercise and repleted by diet. They are related to obesity and insulin resistance. Quantification of IMCL was initially performed invasively, using muscle biopsies with biochemical and/or histological analysis. 1H-magnetic resonance spectroscopy (1H-MRS is now a validated method that allows for not only quantifying IMCL non-invasively and repeatedly, but also assessing IHCL and ICCL. This review summarizes the current available knowledge on the flexibility of ectopic lipids. The available evidence suggests a complex interplay between quantitative and qualitative diet, fat availability (fat mass, insulin action, and physical exercise, all important factors that influence the flexibility of ectopic lipids. Furthermore, the time frame of the intervention on these parameters (short-term vs. long-term appears to be critical. Consequently, standardization of physical activity and diet are critical when assessing ectopic lipids in predefined clinical situations.

Ectopic pregnancy: current clinical trends, a fifteen year study.

Weekes, L R

This paper reviews the clinical recognition, diagnosis, and management of ectopic pregnancy at the Queen of Angels Hospital for the past 15 years. The incidence of ectopic pregnancy to deliveries is 1:195. Pain is the cardinal symptom of ectopic pregnancy, and amenorrhea of some degree was present in all cases. Pelvic inflammatory disease is a factor in the development of tubal pregnancy in some women. A careful history and thorough physical examination are important in making a careful diagnosis. The only laboratory procedures which are of any value are the blood type and the Rh determination. While examination of endometrial tissue obtained by biopsy or curettage has proved useful in ectopic pregnancy diagnosis, it is not totally decisive. Culdocentesis has proved to be the diagnostic procedure of the greatest value in recognizing intraperitoneal hemorrhage and it increases the correct preoperative diagnosis from 65-70% to 95%. Laparoscopy is useful when the physician is in doubt about the nature of the problem and it has produced an increase in the number of ectopic pregnancies diagnosed. Ultrasound is another useful tool in confirming a diagnosis of ectopic pregnancy; its accuracy ranges from 70-92%. A newly developed pregnancy test is more sensitive than conventional pregnancy tests and would be positive for pregnancy. Women who have had a previous ectopic pregnancy have a higher subsequent incidence of persistent infertility, recurrent ectopic pregnancy, and pregnancy wastage; the risk of another ectopic pregnancy increases 30-50 fold. While extopic pregnancy does recur, it is true that about 1/3 of those women do have successful pregnancies. Where previous induced abortion has occurred, there is a 10-fold increased risk of ectopic pregnancy. Women who become pregnant accidentally with an IUD in place have a greater likelihood of experiencing an extrauterine pregnancy. Abdominal pregnancy is often encountered as an aborting ectopic pregnancy during the 1st

Full Text Available Bleeding from ectopic varices, which is rare in patients with portal hypertension, is generally massive and life-threatening. Forty-three patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The frequency of ectopic varices was 43/1218 (3.5% among portal hypertensive patients in our ward. The locations of the ectopic varices were rectal in thirty-two, duodenal in three, intestinal in two, vesical in three, stomal in one, and colonic in two patients. Endoscopic or interventional radiologic treatment was performed successfully for ectopic varices. Hemorrhage from ectopic varices should be kept in mind in patients with portal hypertension presenting with lower gastrointestinal bleeding.

Mineralization inhibitors are required to prevent the precipitation of minerals and inhibit the formation of kidney stones and other ectopic calcifications. In laboratory studies, Fetuin-A as a glycoprotein has inhibited hydroxyapatite precipitation in calcium and phosphate supersaturated solutions; however, information about patients with kidney stones is limited. The aim of this study was to investigate the association of serum and urinary Fetuin-A levels with calcium oxalate kidney stones. In this case-control study, 30 patients with kidney stones and 30 healthy individuals without any history of urolithiasis who were referred to the urology ward of Sina Hospital of Tehran, Iran, in 2015 were entered into the study. All patients underwent computerized tomography scans. After collecting demographic information, serum and urine levels of Fetuin-A and some other calcification inhibitors and promoters, were measured and compared using T-test, Mann-Whitney and logistic regression between the two study groups. Patients with kidney stones, on average, had lower levels of Serum Fetuin-A (1522.27 ±755.39 vs. 1914.64 ±733.76 μg/ml; P = 0.046) as well as lower levels of Urine Fetuin-A (944.62 ±188.5 vs. 1409.68 ±295.26 μg/ml; P <0.001). Multivariate logistic analysis showed that urinary calcium and serum creatinine are the risk factors and Fetuin-A is a urinary protective factor for kidney stones. PFC Our study showed that patients with kidney stones had lower serum and urinary levels of Fetuin-A. In the logistic regression model, urinary Fetuin-A was reported as a protective factor for kidney stones.

Endosonographic Features of Histologically Proven Gastric Ectopic Pancreas

Full Text Available Gastric ectopic pancreas is an uncommon developmental anomaly and its histological diagnosis is usually difficult by using a conventional biopsy forceps. In the literature, most cases of gastric ectopic pancreas were usually diagnosed by gross pattern during endoscopic examination or features of endoscopic ultrasound. In contrast, this disease was seldom diagnosed by histology in clinical practice. Although the typical endoscopic ultrasonographic features of ectopic pancreas include heterogeneous echogenicity, indistinct borders, and a location within 2 or more layers, it can also exhibit hypoechoic homogeneous echogenicity and a distinct border within the fourth sonographic layer (muscularis propria similar to the endoscopic ultrasonographic features of gastrointestinal stromal tumors. In our study, we found that 53% of gastric ectopic pancreas originated within the fourth sonographic layer, demonstrating hypoechoic, homogeneous echogenicity, and distinct borders. Therefore, recognizing endoscopic ultrasonographic features, combining with deep biopsy, endoscopic ultrasound-guided fine needle aspiration/core needle biopsy can prevent conducting unnecessary resection. Surgical resection is the mainstay treatment for symptomatic gastric ectopic pancreas, but endoscopic resection using endoscopic mucosal resection or endoscopic submucosal dissection technique provides an alternative method of removing superficial-type and deep-type gastric ectopic pancreas.

Full Text Available Primary leiomyosarcoma of the kidney is a rare tumor with an aggressive behaviour. A 55-year-old woman presented with a left sided abdominal mass in our outpatient department. Radiologic investigations revealed the mass to be renal in origin with colonic adhesions for which radical nephrectomy and hemicolectomy were done. The tumor completely appeared to replace the left kidney and had a whorled character focally on cut section. Microscopically, spindle cells having malignant features with cigar shaped nuclei were seen. The smooth muscle origin of the cells was confirmed by immunohistochemical positivity for smooth muscle actin. Sarcomatoid variant of the renal cell carcinoma was ruled out as the tumor was negative for cytokeratin. Tumors with spindle cell morphology in the kidney should not always be taken for a sarcomatoid variant of renal cell carcinoma and should be investigated thoroughly.

Point shear wave elastography is a quantitative ultrasound-based imaging method used in the assessment of renal disease. Among point shear wave elastographic options, 2 techniques have been studied considerably: Virtual Touch quantification (VTQ; Siemens AG, Erlangen, Germany) and ElastPQ (EPQ; Philips Healthcare, Bothell, WA). Both rely on the tissue response to an acoustic beam generated by the ultrasound transducer. The data on renal VTQ are more extensive, whereas EPQ has been used less thus far in the assessment of the kidneys. This study aimed to evaluate the performance of EPQ in the kidney and compare it with VTQ. We studied 124 participants using EPQ: 22 with no renal disease and 102 with chronic kidney disease (CKD). Ninety-one were studied with both the EPQ and VTQ methods. We obtained 5 valid measurements in each kidney, expressed in meters per second. The mean kidney stiffness measurements ± SD obtained with EPQ in the healthy control group were as follows: right kidney, 1.23 ± 0.33 m/s; and left kidney, 1.26 ± 0.32 m/s (P = .6). In the patients with CKD (all stages), the mean kidney stiffness measurements obtained were significantly lower: right kidney, 1.09 ± 0.39 m/s; and left kidney, 1.04 ± 0.38 m/s (P = .4). We observed that, similar to VTQ, EPQ values decreased with CKD progression, based on analysis of variance results using different CKD stages. From a receiver operating characteristic curve analysis, the cutoff value for an estimated glomerular filtration rate of less than 45 mL/min was 1.24 m/s, and the value for an estimated glomerular filtration rate of less than 30 mL/min was 1.07 m/s. When using EPQ, the kidney shear wave velocity is decreased in patients with CKD, an observation similar to that obtained by using the VTQ method. © 2018 by the American Institute of Ultrasound in Medicine.

Recent experimental work suggests a paradox: although uremia evokes systemic toxicities, in the setting of AKI, it can induce intrarenal cytoprotective and anti-inflammatory effects. Whether these influences can attenuate post-ischemic kidney disease progression remains unknown. To explore this possibility, male CD-1 mice were subjected to a 30-min unilateral (left) kidney ischemia model, previously shown to reduce renal mass by ∼50% over 2-3 weeks. Stepwise azotemia/acute uremia was superimposed by inducing different lengths of contralateral (right) kidney ischemia (0, 15, 18, 20 min). Subsequent loss of left renal mass (kidney weight) was assessed 2 weeks later and contrasted with the degree of initial azotemia 24-h BUN. A striking correlation between 24-h BUNs and 2-week left renal mass was observed (r, 0.77; P < 0.001). With 20 min of right kidney ischemia, left kidney size was completely preserved. This preservation did not result from increased tubular cell proliferation or decreased microvascular loss, as gauged by KI-67 and CD-34 immunohistochemistry, respectively. Rather, an early reduction in proximal tubule cell dropout (as judged by renal cortical N-acetyl-glucosaminidase content), with a subsequent preservation of tubule mass, was observed. In summary, these findings advance a novel concept: acute uremia can confer early post-ischemic cytoprotection resulting in a slowed progression of post-ischemic kidney disease.

Persistent ectopic pregnancy after milking procedure: Case report

Directory of Open Access Journals (Sweden)

Semra Kayataş

2014-03-01

Full Text Available Ectopic pregnancy is the settlement of the pregnancy product at any site other than the endometrium. The incidence of ectopic pregnancy have increased in the last 20 years. Increased frequency and early diagnosis has led to conservative treatment methods to become more favorable. Follow-up, medical management and surgical managements are considered as conservative methods. As salpingostomy is the most common conservative surgical method, milking is considered as an alternative conservative surgical method. The most important complication of the conservative surgery is the persistence of ectopic pregnancy because of the residual trophoblastic tissue. Since the prediction of the persistent ectopic pregnancy is difficult after the conservative surgery, β-HCG follow up is so important for early diagnosis. In this case report we have discussed the case of the patient who admitted to our clinic with persistent ectopic pregnancy with acute abdomen, after the treatment with milking procedure whom than treated by salpingectomy procedure.

Ectopic recurrence of craniopharyngioma is extremely rare following transcranial procedures of primary tumour. Here we describe 3 new cases of ectopic recurrence along the surgical route after transcranial gross total resection of primary tumour. All 3 cases are male adults--2 of them had papillary-type tumour with the other being adamantinomatous. All ectopic tumours were safely resected via repeated craniotomy. Long-term surveillance of patients with resected craniopharyngioma is essential.

Ectopic pregnancy is one of the most frequent hemorrhagic emergencies encountered in gynecology and obstetrics. The purpose of this 16-month descriptive prospective study at the Ignace Deen Gynecology-Obstetric clinic at Conakry University Hospital in Guinea was to assess diagnostic techniques and therapeutic attitudes regarding ectopic pregnancy in a low-resource setting. The frequency of ectopic pregnancy was 1.4%. Mean patient age was 28.9 years. Ectopic pregnancy was often observed at the second or third pregnancy (47.1%) in women who were giving birth for the second or third time (36.0%) and had a history of sexually transmitted infections (88.2%) or abortions (43.1%). Most women had no schooling (60.8 %), were poor and lived in a marital home (86.3%). Presenting symptoms included the classic triad of amenorrhea (98.0%), abdominopelvic pain (92.2%), and vaginal bleeding (62.7%). Definitive diagnosis was achieved by ultrasound examination in 76.6% of cases and by puncture of the Douglas pouch in 84%. The most frequent site of ectopic pregnancy was the ampulla of the uterine tube (66.9%). Abdominal and ovarian pregnancy was observed in 3 and 4 of the 51 cases respectively. Surgical management was performed in all cases. The most frequent procedure was salpingectomy (80.3%). Proper treatment of sexually transmitted infections (STI), start-up of post-abortion care facilities, and provision of information during early consultation at the first signs of pregnancy would help reduce the frequency and improve the prognosis of ectopic pregnancy.

Point-of-care Ultrasound for the Diagnosis of Ectopic Pregnancy

Full Text Available History of present illness: A 31-year-old female presented to the Emergency Department by ambulance with severe abdominal pain and presyncope. On exam, the patient was hypotensive with suprapubic tenderness. Though the patient denied being pregnant, her labs showed a beta human chorionic gonadotropin (hCG of 38,000 mIU/ml. A bedside transabdominal pelvic ultrasound revealed an ectopic pregnancy and the patient was taken to the operating room for an emergent right salpingectomy. Significant findings: The transabdominal pelvic ultrasound shows an empty uterus (annotated with free fluid and a right sided extrauterine gestational sac representing an ectopic pregnancy (red arrow. Discussion: Ectopic pregnancy is the leading cause of mortality in the first trimester of pregnancy making prompt diagnosis critical.1 Risk factors including history of previous ectopic pregnancy,2 pelvic inflammatory disease,2 increased age,3 and smoking4 can raise suspicion of an ectopic pregnancy. However, the absence of risk factors does not exclude ectopic pregnancy from the differential. Any sexually active female with abdominal pain following a period of amenorrhea should be suspected of an ectopic until proven otherwise. One third of all pregnant women experience abdominal pain and/or vaginal bleeding and 9% of women with an ectopic are asymptomatic. Thus, history alone is insufficient to make the diagnosis.5 In early pregnancy, ectopic pregnancies share the same symptoms as normal pregnancies, including a missed menstrual period, fatigue, and nausea. The first classical signs of an ectopic pregnancy are vaginal bleeding, dizziness, and lower abdominal and/or pelvic pain usually 6 to 8 weeks after a missed menstrual period.5 A meta-analysis of studies on pelvic ultrasonography demonstrated a sensitivity of 99.3% and a negative predictive value of 99.6% for diagnosing ectopic pregnancy and therefore should be utilized as a first-line diagnostic tool for emergency

The ectopic thyroid gland is a rare entity which is mostly found along the line of descent of the thyroid gland. Most of the patients present with midline swelling and usually seek medical attention. Dual ectopic thyroid gland is even rarer. The clinical examination and different imaging modalities establish its diagnosis. Radionuclide studies are highly sensitive and specific in demonstrating the functional tissues in patients with ectopic thyroid, thereby guiding further management. The authors reported a case of ectopic thyroid gland in a girl with midline neck swelling initially, subsequently lost to follow-up. She again presented with enlarged swelling after a period of three years with dual ectopic thyroid in the neck region on thyroid scan. Thyroid scintigraphy demonstrated that progression in the size of ectopic glands was due to neglect in treatment.

Full Text Available INTRODUCTION Endogenous Cushing's syndrome is a clinical state resulting from prolonged, inappropriate exposure to excessive endogenous secretion of Cortisol and hence excess circulating free cortisol, characterized by loss of the normal feedback mechanisms of the hypothalamo-pituitary-adrenal axis and the normal circadian rhythm of cortisol secretion [2]. The etiology of Cushing's syndrome may be excessive ACTH secretion from the pituitary gland, ectopic ACTH secretion by nonpituitary tumor, or excessive autonomous secretion of cortisol from a hyperfunctioning adrenal adenoma or carcinoma. Other than this broad ACTH-dependent and ACTH-independent categories, the syndrome may be caused by ectopic CRH secretion, PPNAD, MAH, ectopic action of GIP or catecholamines, and other adrenel-dependent processes associated with adrenocortical hyperfunction. CASE REPORT A 31 year-old men with b-month history of hyperpigmentation, weight gain and proximal myopathy was refereed to Institute of Endocrinology for evaluation of hypercortisolism. At admission, patient had classic cushingoid habit with plethoric face, dermal and muscle atrophy, abdominal strie rubrae and centripetal obesity. The standard laboratory data showed hyperglycaemia and hypokaliemia with high potassium excretion level. The circadian rhythm of cortisol secretion was blunted, with moderately elevated ACTH level, and without cortisol suppression after low-dose and high-dose dexamethason suppression test. Urinary 5HIAA was elevated. Abdominal and sellar region magnetic resonance imaging was negative. CRH stimulation resulted in ACTH increase of 87% of basal, but without significant increase of cortisol level, only 7%. Thoracal CT scan revealed 14 mm mass in right apical pulmonary segment. A wedge resection of anterior segment of right upper lobe was performed. Microscopic evaluation showed tumor tissue consisting of solid areas of uniform, oval cells with eosinophilic cytoplasm and centrally

Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

Since measuring the size of kidney with sonography becomes an important index for diagnosis, treatment, and prognostic prediction in kidney disease, the accurate measurement and evaluation on this are clinically very important. Accordingly, the purpose of this study was to increase reproducibility and objectivity in measuring the size of kidney by enumerating factors that have an impact for measurement. It targeted 44 adults in Korea at the age of 21-27. It measured in order for both kidneys to be seen most largely while changing a subject-examiner's position in a state of fasting for 8 hours and a transducer's approaching direction. It compared a size of kidney by measuring, respectively, with the same method in 30 minutes and in 1 hour after drinking water in 700-1,000 cc. In case of the lateral approach scan in decubitus position, the average length of the kidney both to the right and the left and the deviation of measurement to be the largest. In NPO(None Per Oral) state, the average length in the right kidney was 10.19cm, and the average length in the left kidney was 10.33 cm. In 60 minutes after taking moisture, the average length in the right kidney was 10.94 cm, and the average length in the left kidney was 11.13 cm. In comparing the average length of the kidney in NPO state and its average length in 60 minutes after taking moisture, the size swelled by 7.3% for the length in the right kidney and by 7.7% in the left, thereby having been indicated to be statistically significant(P<0.003). The measurement in a size of kidney by using ultrasound may be measured differently depending on a patient's state of taking moisture and a transducer's approaching direction. It is thought that when the measurement in a size of kidney is especially important clinically, the intake and intake time in moisture need to be considered and that measuring with the posterior approach in prone position is a good method aiming to increase reproducibility in

Adult Dioctophyma renale occupied the enlarged renal pelvis of the right kidney of naturally infected mink. Lesions in the kidney parenchyma consisted of connective tissue proliferation in the interstitial tissue, tubular atrophy and fibrosis, and periglomerular fibrosis. The luminal surface of the renal pelvis wall was formed of numerous papillae covered with transitional epithelium. The nematodes in the lumen were bathed in an albuminous fluid containing red blood cells, epithelial cells and D. renale eggs. The left (uninfected) kidney was 60% larger than the left kidney of normal mink.

Orthodontic management of buccally erupted ectopic canine with two case reports

Full Text Available Ectopic canine teeth develop displaced from their normal position. Any permanent tooth can be ectopic, and the cause may be both genetic and environmental. Orthodontic treatment is justified because ectopic canine teeth can migrate in the jaw bone and may damage the adjacent teeth roots and bone. Orthodontic treatment is also justifiable for aesthetic reasons. Diagnosis and treatment of ectopically erupting permanent maxillary canines requires timely management by the orthodontist. Internal or external root resorption of teeth adjacent to the ectopic canine is the most common sequel. Malocclusion with severe crowding is difficult to treat without extraction. Non-extraction treatment of ectopic canines can compromise the patient′s profile. This article represents two cases of extraction treatment approach for buccally displaced or ectopic canine in a patient with severe crowding in the mandibular arch.

The objectives were to determine the resistive index (RI) in normal cats and in cats with various renal diseases, and to evaluate the effect of age on RI. The subjects were cats that had ultrasonography (US) of the urinary tract and RI measurement at our centre between January 2003 and April 2014. Based on clinical evaluation, biochemical and haematological tests, urinalysis and US, the cats were classified as healthy or diseased. RI measurements were made from the interlobar or arcuate arteries. Data were analysed for differences between the right and the left kidney, the two sexes, different age groups in healthy cats, and between healthy and diseased cats. A total of 116 cats (68 males, 48 females) were included: 24 healthy and 92 diseased. In the healthy cats, RI (mean ± SD) differed significantly (P = 0.02) between the right kidney (0.54 ± 0.07) and the left kidney (0.59 ± 0.08). For the left kidney, RI was significantly higher in cats with chronic kidney disease (0.73 ± 0.12) and acute kidney injury (0.72 ± 0.08) (P = 0.0008). For the right kidney, RI was significantly higher in cats with chronic kidney disease (0.72 ± 0.11), acute kidney injury (0.74 ± 0.08), polycystic kidney disease (0.77 ± 0.11) and renal tumour (0.74 ± 0.001) (P cats, useful in the differential diagnosis of diffuse renal diseases. While it does not change with the age of the cat, ultrasonographers should be aware that RI may differ between the two kidneys. © ISFM and AAFP 2015.

Full Text Available In our case report, abdominal multi-detector computed tomography was used for the pre-operative anatomy evaluation in a living kidney donor. The early phase of the test revealed normal kidneys in the donor. The vascular phase detected a venous variant on the left side: An inferior renal capsular vein, which had a loop and a retro-aortic course. This preoperative knowledge was crucial for the laparoscopic nephrectomy as a surgical procedure for harvesting kidney from the living donor.

Our objective is to describe off-label use of methotrexate in ectopic pregnancy treatment using evidence based medicine. The patient group includes all women with a pregnancy outside the usual endometrium, or of unknown location. Method used was a Medline search on ectopic pregnancy managed using methotrexate treatment; evidence synthesis was done based on this current literature analysis. Level of evidence (LE) were given according to the centre for evidence base medicine rules. Grade was proposed for guidelines but no recommendation was possible as misoprostol is off label use for all the indications studied. In the absence of any contraindication, the protocol recommended for medical treatment of ectopic pregnancy is a single intramuscular injection of methotrexate (MTX) at a dosage of 1mg/kg or 50mg/m(2) (Grade A). It can be repeated once at the same dose should the hCG concentration not fall sufficiently. Pretreatment laboratory results must include a complete blood count and kidney and liver function tests (in accordance with its marketing authorization). MTX is an alternative to conservative treatment such as laparoscopic salpingotomy for uncomplicated tubal pregnancy (Grade A) with pretreatment hCG levels≤5000IU/l (Grade B). Expectant management is preferred for hCG levelslocation persisting more than 10days in an asymptomatic woman who has an hCG level>2000IU/l, routine MTX treatment is an option. MTX is not indicated for combination with treatments such as mifepristone or potassium. Copyright © 2016. Published by Elsevier Ireland Ltd.

2011-08-01

Ocular coloboma is sometimes accompanied by corectopia in humans and therefore ectopic pupil may indicate ocular coloboma in experimental animals. The RCS strain of rats has a low incidence of microphthalmia. We found that inferior ectopic pupil is associated exclusively with small-sized eyes in this strain. The objective of the current study was to evaluate whether inferior ectopic pupil is associated with iridal coloboma and other types of ocular coloboma in RCS rats. Both eyes of RCS rats were examined clinically, and those with inferior ectopic pupils underwent morphologic and morphometric examinations. In a prenatal study, coronal serial sections of eyeballs from fetuses at gestational day 16.5 were examined by using light microscopy. Ectopic pupils in RCS rats were found exclusively in an inferior position, where the iris was shortened. Fundic examination revealed severe chorioretinal coloboma in all cases of inferior ectopic pupil. The morphologic characteristics closely resembled those of chorioretinal coloboma in humans. Histopathologic examination of primordia showed incomplete closure of the optic fissure in 4 eyeballs of RCS fetuses. Neither F(1) rats nor N(2) (progeny of RCS × BN matings) displayed any ocular anomalies, including ectopic pupils. The RCS strain is a suitable model for human ocular coloboma, and inferior ectopic pupil appears to be a strong indicator of ocular coloboma.

Full Text Available Ectopic ovaries are a rare finding in the literature, with fewer than 50 published cases to date. This phenomenon has been found in the omentum, bladder, mesentery, and uterus; attached to the colon; inside the left labia majora; and in the kidney. Various etiologies have been proposed, including postsurgical or postinflammatory transplantation, malignant origins, and abnormal embryologic development. We report the ultrasonographic, computed tomographic (CT, and magnetic resonance (MR imaging of, what is to the best of our knowledge, the first case of an intrahepatic ectopic ovary.

Full Text Available Cornual ectopic gestation is one of the causes of “Maternal near miss” cases. In the modern era of IVF treatments and better imaging techniques, more number of cases of cornual ectopic pregnancies is being diagnosed and treated both by conservative and radical methods. Here, we report a case of a recurrent cornual ectopic pregnancy in the early second trimester, which was managed by hysterectomy due to uncontrolled haemorrhage. Thirty five year old Mrs. S, Gravida 4, para2, with one previous ectopic pregnancy presented to the obstetric casualty with acute abdominal pain at 15 weeks +2 days of gestation. On vaginal examination, there was right fornicial fullness and both the fornices were tender. Cervical motion tenderness was also present. On review of her previous records, dating scan done at 8 to 9 weeks showed normal intrauterine pregnancy. An emergency scan was carried out which revealed an empty uterine cavity with gestational sac measuring 3.6×4.4×4.6 cms seen outside the uterus just above the fundus with absent cardiac activity. There was evidence of haemoperitoneum, therefore she was diagnosed with recurrent ruptured ectopic pregnancy.

A 7-week-old Appaloosa filly was admitted for persistent urinary incontinence since birth. Vaginal speculum examination revealed urine flowing from an opening in the right vaginal wall. Cytoscopy demonstrated that the ureters did not terminate at the bladder. The endoscope passed easily from the vagina directly into a dilated right ureter. An excretory urogram confirmed the vaginal termination of at least one ureter, based upon extensive filling of the vagina with contrast media in the absence of bladder filling. Bilateral hydroureter and dilated renal pelves were demonstrated both by excretory urography and by urtrasonography. Euthanasia was required by the owner in lieu of attempted surgical correction. At necroscopy, it was confirmed that the right ureter entered the vagina and the left ureter terminated at the urethra. The diagnosis of bilateral ectopic ureter in this foal was suggested by this history and clinical signs, supported by endoscopy and ultrasonography, and confirmed by excretory urography and necropsy. This case establishes the value of diagnostic imaging techniques in the antemortem diagnosis of ectopic ureter

Full Text Available This is a 15-year-old female who presented with sudden onset left flank pain associated with nausea and vomiting and a history of weight loss. Radiological investigation revealed a large non-obstructive tumor involving the lower pole of the left kidney which was primarily thought to be a renal cell carcinoma. She underwent left open radical nephrectomy with adrenalectomy. Histopathology of the resected specimen showed features of Ewing’s sarcoma of the kidney which was confirmed by cytogenetic analysis. This is a rare disease especially in the pediatric group and in reporting such a rare case we hope it helps in identifying a potential course of the disease and its response to the involved treatment.

Ectopic ACTH-syndrome is a rare cause of Cushing's disease. Despite extensive diagnostic procedures the source of ACTH secretion often remains occult. This case describes a 45-year old woman with an ectopic Cushing's syndrome. Extensive imaging procedures including CT scan of chest and abdomen, octreotide scan and MRI of the chest and pituitary did not reveal the source of ACTH secretion. In consideration of an occult source of ACTH secretion we started a therapeutic trial with cabergoline (0.5 mg/d), a dopamine receptor agonist, which has been shown to be effective in ectopic Cushing's syndrome. 2 months after cabergoline treatment had been initiated, ACTH and cortisol levels normalized in association with significant improvement of the clinical symptoms. During follow-up a [(68)Ga-DOTA-dPhe(1), Tyr(3)]-octreotate ([(68)Ga-DOTA]-TATE) PET-CT was performed revealing a somatostatin receptor positive lesion in the right sphenoidal sinus suggesting the source of ACTH secretion. The patient was cured by transnasal resection of the polypoid lesion, which was immunohistochemically characterized as an ACTH-positive neuroendocrine tumor. This case report demonstrates the management of ectopic ACTH-syndrome by molecularly -targeted therapy with dopamine receptor -agonists as well as improved detection of the ectopic ACTH source by novel imaging modalities, such as [(68)Ga-DOTA]-TATE PET specifically targeting somatostatin receptor subtype-2 with high affinity. © J.

Full Text Available Aim: The goal of this study was to identify potential risk factors for ectopic pregnancy in women followed in German gynecological practices.Methods: The present study included pregnant women diagnosed with ectopic pregnancy and pregnant women without ectopic pregnancy followed in 262 gynecological practices between January 2012 and December 2016. The effects of demographic and clinical variables on the risk of developing ectopic pregnancy were estimated using a multivariate logistic regression model. Results: This study included 3,003 women with ectopic pregnancy and 97,194 women without ectopic pregnancy. The mean age was 31.4 years (SD=5.9 years in ectopic pregnancy patients and 31.1 years (SD=5.6 years in non-ectopic pregnancy patients. Women aged 36–40 (OR=1.12 and 41–45 years (OR=1.46 were at a higher risk of ectopic pregnancy than women aged 31–35 years. Prior ectopic pregnancy was strongly associated with a risk of recurring ectopic pregnancy (OR=8.17. Prior genital surgery (OR=2.67, endometriosis (OR=1.51, and eight other gynecological diseases were also positively associated with ectopic pregnancy (ORs ranging from 1.19 to 2.06. Finally, there was a 1.80-fold increase in women previously diagnosed with psychiatric disorders.Conclusions: Prior ectopic pregnancy and prior genital surgery were strongly associated with ectopic pregnancy in women followed in German gynecological practices. Psychiatric diseases had an additional impact on the risk of ectopic pregnancy.

Graffigna, A; Vigano, M; Pagani, F; Salerno, G

1992-08-01

Atrial tachycardia is an infrequent but potentially dangerous arrhythmia which often determines cardiac enlargement. Surgical ablation of the arrhythmia is effective and safe, provided a careful atrial mapping is performed and the surgical technique is tailored to the individual focus location. Eight patients underwent surgical ablation of ectopic atrial tachycardia between 1977 and 1990. Different techniques were adopted for each patient according to the anatomical location of the focus and possibly associated arrhythmias. Whenever possible, a closed heart procedure was chosen. In 1 patient a double focal origin was found and treated by separate procedures. In 1 patient with ostium secundum atrial septal defect and atrial flutter, surgical isolation of the right appendage and the ectopic focus was performed. In all patients ectopic atrial tachycardia was ablated with maintenance of the sinoatrial and atrioventricular nodal function as well as internodal conduction. In follow-up up to December 1991, no recurrency was recorded.

Horseshoe kidney is often associated with other congenital abnormalities and obstruction of pyeloureteral segment (PUS). The aim of our study was to evaluate the results of laparoscopic pyeloplasty (LP) in patients with hydronephrosis of horseshoe kidney. From February 2010 to March 2016, 130 patients underwent LP. Ten (7.7%) of them (6 men and 4 women) had a hydronephrosis of horseshoe kidney. Left and right PUS obstruction were diagnosed in 6 and 4 patients, respectively. All the patients underwent PL transperitoneally using the Anderson-Hynes method. In patients with left hydronephrosis, surgery was performed by transmesenteric access. There were no cases of conversion to open surgery and drainage urine leakage. Exacerbation of chronic pyelonephritis was observed in 2 cases. Operating time ranged from 125 to 160 minutes (median 130 minutes), time of performing pyeloureteral anastomosis - from 50 to 105 minutes. Patients were ambulated within the first day after surgery, the length of hospital stay was 3 - 4 days. One patient with recurrent strictures of PUS 8 months after the LP underwent retrograde endopyelotomy with the placement of endopyelotomy stent. The effectiveness of operations over a 6-38 month follow-up was 90%. LP is an effective and minimally invasive treatment for patients with hydronephrosis of horseshoe kidney. In a left PUS obstruction, pyeloplasty can be performed using transmesenteric access.

Ectopic pituitary adenoma presenting as midline nasopharyngeal mass.

LENUS (Irish Health Repository)

Ali, R

2012-02-01

INTRODUCTION: Ectopic pituitary adenomas are extremely rare. We report a case of ectopic pituitary adenoma in the midline of the nasopharynx. This adenoma probably arose from the pharyngeal remnant of Rathke\\'s pouch. METHODS: We discuss a case of a lady who presented to our unit with 2 months history of dryness and sensation of lump in her throat and a long standing history of hypothyroidism. Examination of nasopharynx revealed a smooth and fluctuant midline mass. CT scan of nose and paranasal sinuses confirmed the midline mass with small defect communicating with the sphenoid sinus. An initial diagnosis of Thornwaldt\\'s cyst was made and she underwent upper aerodigestive tract endoscopy and marsupialization of the mass. Histopathological examination revealed ectopic pituitary adenoma. CONCLUSION: Ectopic pituitary adenoma is an important differential diagnosis for a midline nasopharyngeal mass. It is recommended that prior to surgical resection of midline nasopharyngeal mass biopsy is taken and MRI is performed.

Vitamin K supplementation increases vitamin K tissue levels but fails to counteract ectopic calcification in a mouse model for pseudoxanthoma elasticum.

Pseudoxanthoma elasticum (PXE) is an autosomal recessive disorder in which calcification of connective tissue leads to pathology in skin, eye and blood vessels. PXE is caused by mutations in ABCC6. High expression of this transporter in the basolateral hepatocyte membrane suggests that it secretes an as-yet elusive factor into the circulation which prevents ectopic calcification. Utilizing our Abcc6 (-/-) mouse model for PXE, we tested the hypothesis that this factor is vitamin K (precursor) (Borst et al. 2008, Cell Cycle). For 3 months, Abcc6 (-/-) and wild-type mice were put on diets containing either the minimum dose of vitamin K required for normal blood coagulation or a dose that was 100 times higher. Vitamin K was supplied as menaquinone-7 (MK-7). Ectopic calcification was monitored in vivo by monthly micro-CT scans of the snout, as the PXE mouse model develops a characteristic connective tissue mineralization at the base of the whiskers. In addition, calcification of kidney arteries was measured by histology. Results show that supplemental MK-7 had no effect on ectopic calcification in Abcc6 ( -/- ) mice. MK-7 supplementation increased vitamin K levels (in skin, heart and brain) in wild-type and in Abcc6 (-/-) mice. Vitamin K tissue levels did not depend on Abcc6 genotype. In conclusion, dietary MK-7 supplementation increased vitamin K tissue levels in the PXE mouse model but failed to counteract ectopic calcification. Hence, we obtained no support for the hypothesis that Abcc6 transports vitamin K and that PXE can be cured by increasing tissue levels of vitamin K.

2005-07-01

The purpose of this study was to determine the characteristics and occurrence of the ectopic eruption of the maxillary first permanent molar in a sample of growing Spanish children. A descriptive, observational, retrospective study was done using the radiographs of 509 consecutive patients, who were in the first phase of mixed dentition. A method was designed to evaluate the amount of pathologic resorption of the second maxillary primary molar and the impaction of the first permanent molar measured in millimeters. Statistical analysis of the studied variables was done using chi-square, analysis of variance, and Pearson correlation coefficient. The frequency of occurrence was 4.3% with no differences in both sexes. Of these, 36.4% were unilateral and 63.6% bilateral with a right:left relation of 3:1. Of the 36 ectopic molars, 69.4% self-corrected spontaneously. In such cases, the pathological resorption of the root of the second maxillary primary molar and its adverse clinical implications were persistent. The relation between self-correction and impaction was 2.27:1. The average impaction on the right side was 2.91 mm and 1.6 mm on the left side. Correlation between the magnitude of resorption and grade of impaction was not observed. Although resorption was found on grades I and II, spontaneous self-correction could occur without arch length loss. However, on grade III or more, therapeutic intervention has to be done. The benefit of early diagnosis and treatment of the maxillary first permanent molar is the prevention of the premature loss of second maxillary deciduous molar and the resulting malocclusion.

Ectopic Pregnancy After Plan B Emergency Contraceptive Use.

Science.gov (United States)

Steele, Brianne Jo; Layman, Kerri

2016-04-01

Pregnancy outcomes after emergency contraceptive use has been debated over time, but review of the literature includes mechanisms by which these medications may increase the chance of an ectopic pregnancy. Such cases are infrequently reported, and many emergency providers may not readily consider this possibility when treating patients. This is a case presentation of ectopic pregnancy in a patient who had recently used Plan B (levonorgestrel) emergency contraceptive. She presented with abdominal pain and vaginal spotting, and was evaluated by serum testing and pelvic ultrasound. She was discovered to have a right adnexal pregnancy. She was treated initially with methotrexate, though she ultimately required surgery for definitive treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report aims to bring a unique clinical case to the attention of emergency providers. The goal is to review research on the topic of levonorgestrel use and the incidence of ectopic pregnancies. The mechanism of action of this emergency contraceptive is addressed, and though no definite causal relationship is known between levonorgestrel and ectopic pregnancies, there is a pharmacologic explanation for how this event may occur after use of this medication. Ultimately, the emergency provider will be reminded of the importance of educating the patient on the possible outcomes after its use, including failure of an emergency contraceptive and the potential of ectopic pregnancy.

Mechanisms of Ectopic Gene Conversion

Directory of Open Access Journals (Sweden)

P.J. Hastings

2010-11-01

Full Text Available Gene conversion (conversion, the unidirectional transfer of DNA sequence information, occurs as a byproduct of recombinational repair of broken or damaged DNA molecules. Whereas excision repair processes replace damaged DNA by copying the complementary sequence from the undamaged strand of duplex DNA, recombinational mechanisms copy similar sequence, usually in another molecule, to replace the damaged sequence. In mitotic cells the other molecule is usually a sister chromatid, and the repair does not lead to genetic change. Less often a homologous chromosome or homologous sequence in an ectopic position is used. Conversion results from repair in two ways. First, if there was a double-strand gap at the site of a break, homologous sequence will be used as the template for synthesis to fill the gap, thus transferring sequence information in both strands. Second, recombinational repair uses complementary base pairing, and the heteroduplex molecule so formed is a source of conversion, both as heteroduplex and when donor (undamaged template information is retained after correction of mismatched bases in heteroduplex. There are mechanisms that favour the use of sister molecules that must fail before ectopic homology can be used. Meiotic recombination events lead to the formation of crossovers required in meiosis for orderly segregation of pairs of homologous chromosomes. These events result from recombinational repair of programmed double-strand breaks, but in contrast with mitotic recombination, meiotic recombinational events occur predominantly between homologous chromosomes, so that transfer of sequence differences by conversion is very frequent. Transient recombination events that do not form crossovers form both between homologous chromosomes and between regions of ectopic homology, and leave their mark in the occurrence of frequent non-crossover conversion, including ectopic conversion.

Does the risk of adverse outcomes at the time of ectopic pregnancy vary by race/ethnicity among women receiving Medicaid, the public health insurance program for low-income people in the USA? Among Medicaid beneficiaries with ectopic pregnancy, 11% experienced at least one complication, and women from all racial/ethnic minority groups were significantly more likely than whites to experience complications. In this population of Medicaid recipients, African American women are significantly more likely than whites to experience ectopic pregnancy, but the risk of adverse outcomes has not previously been assessed. We conducted a cross-sectional observational study of all women (n = 19 135 106) ages 15-44 enrolled in Medicaid for any amount of time during 2004-2008 who lived in one of the following 14 US states: Arizona; California; Colorado; Florida; Illinois; Indiana; Iowa; Louisiana; Massachusetts; Michigan; Minnesota; Mississippi; New York; and Texas. We analyzed Medicaid claims records for inpatient and outpatient encounters and identified ectopic pregnancies with a principal diagnosis code for ectopic pregnancy from 2004-2008. We calculated the ectopic pregnancy complication rate as the number of ectopic pregnancies with at least one complication (blood transfusion, hysterectomy, any sterilization, or length-of-stay (LOS) > 2 days) divided by the total number of ectopic pregnancies. We used Poisson regression to assess the risk of ectopic pregnancy complication by race/ethnicity. Secondary outcomes were each individual complication, and ectopic pregnancy-related death. We calculated the ectopic pregnancy mortality ratio as the number of deaths divided by live births. Ectopic pregnancy-associated complications occurred in 11% of cases. Controlling for age and state, the risk of any complication was significantly higher among women who were black (incidence risk ratio [IRR] 1.47, 95% CI 1.43-1.53, P American Indian/Alaskan Native (IRR 1.34 95% CI 1.16-1.55, P white

Full Text Available BACKGROUND To study the proportion of ectopic pregnancies with a history of female sterilisation and to assess the risk factors associated with post sterilisation ectopic pregnancy. MATERIALS AND METHODS This is a descriptive cross-sectional study. Cases of ectopic pregnancy that were admitted in Department of Obstetrics and Gynaecology, Kozhikode, from February 2014 to July 2015 are included in the study. Details of patient were collected and they were examined in person. Investigations were recorded and clinical findings were noted. Later outcome of cases was also recorded. Data from the study was coded and entered in MS Excel and analysed with SPSS software. RESULTS There were 372 cases of ectopic pregnancies, of which 51 had history of female sterilisation. Ectopic tubal pregnancies after tubal sterilisation accounted for 13.7% of all the ectopic pregnancies in this study. 45% cases occurred in patients less than 30 years. More than 75% cases of ectopic pregnancy in the study presented at less than 7 weeks. Abdominal pain was the main symptom with which they presented. Out of the 51 cases, more than 80% patients had undergone sterilisation by modified Pomeroy’s technique while 17.6% cases had undergone laparoscopic sterilisation. 98% of the patients had their sterilisation done before 30 years of age. 64.7% cases had undergone sterilisation from a secondary care centre while 35.5% had it from a tertiary care centre. In the present study, more than half of the cases presented (as ectopic pregnancy within 5 years after sterilisation. 15% cases had history of pelvic inflammatory disease. Bilateral near total salpingectomy was done in all cases. CONCLUSION In the present study, it is observed that ectopic pregnancies following female sterilisation are not rare. It constituted 13.7% cases of ectopic pregnancies. There may be a delay in diagnosis as there is a history of sterilisation. Absence of amenorrhoea does not rule out ectopic. Most of

Objective To evaluate the existing data to estimate the rate of ectopic pregnancy among emergency contraceptive pill treatment failures. Data Sources Our initial reference list was generated from a 2008 Cochrane review of emergency contraception. In August 2009, we searched Biosys Previews, the Cochrane Database of Systematic Reviews, Medline, Global Health Database, Health Source: Popline, and Wanfang Data (a Chinese database). Methods of Study Selection This study included data from 136 studies which followed a defined population of women treated one time with emergency contraceptive pills (either mifepristone or levonorgestrel), and in which the number and location of pregnancies were ascertained. Results Data from each article were abstracted independently by two reviewers. In the studies of mifepristone, 3 out of 494 (0.6%) pregnancies were ectopic; in the levonorgestrel studies, 3 out of 307 (1%) were ectopic. Conclusion The rate of ectopic pregnancy when treatment with emergency contraceptive pills fails does not exceed the rate observed in the general population. Since emergency contraceptive pills are effective in lowering the risk of pregnancy, their use should reduce the chance that an act of intercourse will result in ectopic pregnancy. PMID:20502299

Full Text Available The present research provides analysis of results of preoperative examination of 680 patients with ectopic pregnancy depending on the range of surgical treatment. It has been shown that in case of progressive ectopic pregnancy the diagnostic significance of concentrations of human chorionic gonadotropin, transvaginal examination and laparos-copy depends on the duration of pregnancy. When the term of ectopic pregnancy is 3-4 weeks monitoring of p chorionic gonadotropin in blood serum (99.5%, transvaginal examination (58% and laparoscopy (78.5% are more informative. When the term of ectopic pregnancy is more than 4 weeks there is a high diagnostic value of monitoring p-subunit of chorionic gonadotropin (99.5%, transvaginal examination (68% and laparoscopy (99,5%. The research has proved that pregnancy period of 3-4 weeks is optimal for laparoscopy and other operations

Median ectopic thyroid may be encountered anywhere from the foramen caecum to the diaphragm. Non lingual median aberrant thyroid (incomplete descent) usually found in the infrahyoid region and malignant transformation in this ectopic thyroid tissue is very rare. We report an extremely rare case of papillary carcinoma in non lingual median aberrant thyroid in a 25-year-old female. The differentiation between a carcinoma arising in the median ectopic thyroid tissue and a metastatic papillary carcinoma from an occult primary in the main thyroid gland is also discussed.

Full Text Available The aim of our study was to investigate the left ventricular (LV echocardiographic parameters and estimate the antiremodeling efficacy of eprosartan and lercanidipine in patients with CKD, depending on the presence or absence of diabetic nephropathy (DN. Materials and Methods: The study included 121 patients (mean age 52.4±5.7 years with CKD stage 3 (KDOQI, 2002. Patients were distributed in two groups according to the etiology of CKD. Group 1 consisted of 67 patients with non-diabetic CKD. Group 2 consisted of 54 CKD patients with DN. All patients had arterial hypertension grade 1 or 2 (ESH/ESC, 2013. All patients underwent clinical examination, echocardiography; GFR was estimated by the Cockcroft-Gault formula. Stages of chronic kidney disease (CKD were determined according to the KDOQI 2002 classification. Eprosartan and lercanidipine were prescribed to patients after one week of lavage from previous antihypertensive therapy. This 6-month follow-up study compared the effectiveness of two courses of treatment. Results: LVH was observed in all CKD patients regardless of the presence or absence of DN. Eprosartan and lercanidipine showed the high antihypertensive efficacy expressing a reliable decrease in absolute values of SBP and DBP. In CKD patients with DN, on the background of a comparable antihypertensive effect, eprosartan, in comparison with lercanidipine, showed a more pronounced effect on the LV echocardiographic parameters associated with LVH regression.

2005-12-01

A 14-year-old neutered male Bearded Collie was presented with a history of recurrent, intermittent urinary incontinence of 7 years duration. A large, firm, non-painful mass was found in the mid-abdominal region on palpation. Ultrasonography of the mass revealed a compartmentalised structure with mixed echogenicity, and which did not appear to be associated with any of the abdominal organs. Ultrasound-guided fine needle aspirates contained several clusters of epithelial cells with cytological features of hepatocytes. At exploratory laparotomy, the mass was found in the gastrosplenic ligament within the greater omentum. PATHOLOGICAL FINDINGS AND DIAGNOSIS: Histopathologically, the mass consisted of sheets of hepatocytes, but without the characteristic hepatic architecture. The cells showed moderate variation in nuclear size and were sometimes binucleate. A diagnosis of hepatocellular carcinoma (HCC) in the mesentery was made. The presence of ectopic hepatic tissue has been reported rarely in man and cats, but not in the dog. Neoplastic transformation of ectopic hepatic tissue is seen in man. This is the first report of the presentation, clinical findings and treatment of a dog with ectopic HCC.

Laparoscopic splenectomy for a simultaneous wandering spleen along with an ectopic accessory spleen. Case report and review of the literature

Directory of Open Access Journals (Sweden)

Antonia Rizzuto

Full Text Available Background: Wandering spleen and accessory spleen are uncommon entity occurring during embryonic development. Wandering spleen results in an excessive mobility and migration of the spleen from its normal position in the left hypochondrium while accessory spleen is characterized by ectopic splenic masses or tissue disjointed from the main body of spleen.Due to the nonspecific and multiple symptoms the clinical diagnosis of both conditions is uncertain even with imaging techniques, such as CT and MRI. The coexistence of both diseases (wandering spleen ad accessory spleen is uncommon. Case report: A 17–year old European female with a history of minor beta thalassemia and recurrent attacks of abdominal pain. Pre- operative management consisted of routine laboratory tests, ultrasound, CT scan. An ectopic spleen along with an accessory spleen were diagnosed. After a multidisciplinary board a laparoscopic splenectomy was performed. Post-operative recovery was uneventful, and the patient was discharged on the 6th post-operative day with the indication to continue the therapy with low molecular weight heparin (LMWH for 30 days Conclusions: This case represents a simultaneous condition of wandering splenomegaly along with an ectopic wandering spleen. The coexistence of these two rare conditions is peculiar such as the age of the patient, as literature reports such diseases to affect children or more commonly people in the range of 20–40 years of age. Laparoscopic treatment for this particular condition is also unusual. Keywords: Ectopic spleen, Wandering spleen, Laparoscopic splenectomy

Full Text Available Ectopic tooth eruption in a non-dental area is a rare entity, and is most common in oral cavity. There have been a few case reports of teeth erupting in mandibular condyle, chin, palate, coronoid process, and maxillary sinus. Ectopic tooth in the maxillary sinus are found incidentally on routine radiological examination, same time they can be symptomatic and associated with pathologies usually dentigerous cyst or odontogenic keratocyst. Facial pain, purulent rhinorrhoea, epistaxis, headache, swelling, and epiphora-related naso-lacrimal duct obstruction can also be seen. By Caldwell-Luc procedure the ectopic teeth within the maxillary sinus are often removed. In this study, a case of ectopic maxillary third molar tooth on right maxillary sinus is presented.

This study was done to analyse colour Doppler ultrasound (CDUS) findings in patients with dual kidney transplantation (DKT) and to compare renal volume and resistive index (RI) values between DKT and single kidney transplantation (SKT). We reviewed the clinical and imaging findings [30 CDUS, five magnetic resonance (MR) and one computed tomography (CT) examination] in 30 patients with DKT (23 men and seven women; median age 65 years; range 55-82). Three patients had clinical signs of graft malfunction. Renal volumes and RI were compared with those of 14 SKT patients and comparable levels of renal function. Three patients had graft dysfunction: one had chronic rejection and two had pathologies involving one kidney only (one encrusted pyeloureteritis of a left graft and one occluded main artery of a left graft). Asymptomatic unilateral pathologies were seen in six cases. In asymptomatic DKT patients, no significant differences in length, volume, cortical echogenicity and RI between the two kidneys were observed; DKTs were smaller (median volume 116.7 vs. 171.6 cc) and had higher RIs (0.76 vs. 0.68) (pDKT, allowing detection of clinically unsuspected unilateral diseases. At comparable levels of renal function, DKT patients had higher RI and lower volumes than SKT patients.

Full Text Available Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.

The common sites of breast cancer metastases include bones, lung, brain, and liver. Renal metastasis from the breast is rare. We report a case of breast cancer metastatic to the kidney with extension into the renal vein. A 40-year-old woman had undergone left mastectomy for breast cancer at the age of 38. A gastric tumor, which was later proved to be metastasis from breast cancer, was detected by endoscopy. Computed tomography performed for further examination of the gastric tumor revealed a large left renal tumor with extension into the left renal vein. It mimicked a primary renal tumor. Percutaneous biopsy of the renal tumor confirmed metastasis from breast cancer. Surgical intervention of the stomach and the kidney was avoided, and she was treated with systemic chemotherapy. Breast cancer metastatic to the kidney may present a solitary renal mass with extension into the renal vein, which mimics a primary renal tumor.

This study was performed to determine the sonographic dimensions of normal kidney in Korean male and to investigate their correlation with age, height, and weight. The ultrasound examinations were performed in 532healthy Korean male from July 1993 to December 1993. We measured the length, the width, and the thickness of both kidneys and those of both central echogenic area. Then renal shape index (RSI), renal volume (RV), volume of central (CEV) echogenic area, and renal parenchymal volume (RPV) were calculated from these measurements. The mean RV of the right kidney was 129.30 ± 30.20 cm 3 (Mean ± Standard Deviation) and that of the left kidney was 137.06± 29.73 cm 3 . Meanwhile the mean renal length of right kidney was 10.42 ± 0.61 cm and that of the left kidney was 10.63 ± 0.62 cm being distributed more compactly near mean value than the RV. Therefore the renal length could be more useful than RV in discrimination of abnormally increased or decreased kidney. While renal width, thickness and RV were increased with age, CEV showed no corresponding change. Therefore, the increase in RV could be attributed to the increase in RPV. Meanwhile the RSI was decreased with age. The renal length, renal thickness,thickness of central echogenic area, RV, CEV, and RPV showed strong correlation with weight. The renal length and the length of central echogenic area showed good correlation with height

Ectopic recurrence of craniopharyngioma in the cerebellopontine angle after surgical resection of a suprasellar craniopharyngioma is rare. Thus, only 5 cases were reported with a delay ranging between 4 and 26 years after removal of the primary tumor. We report a unique case of ectopic recurrence of craniopharyngioma in the cerebellopontine angle, which occurred at only 4 months after surgical resection of the primary tumor. A 24-year-old man underwent resection of a suprasellar craniopharyngioma via a right pterional approach four months earlier. During follow-up, cerebral magnetic resonance imaging (MRI) showed a round homogeneous contrast-enhancing tumor in the right cerebellopontine angle with neither relation to the internal auditory canal nor to the dura mater. After microsurgical resection, histopathological findings revealed ectopic recurrence of craniopharyngioma with similar tumors like the primary tumor. Although infrequent, craniopharyngioma may disseminate via the cerebrospinal fluid during surgical resection and grow in an ectopic place. Early follow-up and MRI scan following resection of a craniopharyngioma is recommended.

2011-04-01

Our objective is to present a short series of four rare cases of ectopic olfactory neuroblastoma. Our methods present four case reports of ectopic olfactory neuroblastoma and a review of the literature for management and treatment of this disease. The results indicate short case series reports of ectopic olfactory neuroblastoma arising from the anterior ethmoidal sinuses, the nasopharynx, the lateral nasal wall and the floor of the nose. The discussion focuses on likely origins of ectopic olfactory neuroblastoma, its clinical features and management. We conclude that ectopic olfactory neuroblastoma is a rare disease. Treatment principles are the same for non-ectopic disease and guided by extension into adjacent structures such as the orbit or anterior cranial fossa and usually involves surgery with or without adjuvant radiotherapy.

The purpose of this study was to determine the long-term clinical outcome of patients with ectopic atrial tachycardias treated surgically. Ectopic atrial tachycardia is an uncommon arrhythmia that can be symptomatic and is associated with the development of a cardiomyopathy. Management strategies are not well defined because of the paucity of data on the long-term effectiveness of pharmacologic and nonpharmacologic therapies. The long-term clinical impact of medical and surgical therapy was determined in 15 consecutive patients with ectopic atrial tachycardia. All 15 patients were initially treated with antiarrhythmic drugs (mean 5.7 +/- 2.2 drugs/patient). An effective drug regimen was identified in only 5 (33%) of the 15 patients; the remaining 10 patients were treated surgically. In each, individualized surgical procedures were guided by computer-assisted intraoperative mapping, with atrial plaques comprising up to 156 electrodes. Focal ablation was performed in four patients and atrial isolation procedures in six. The 10 patients treated surgically were followed up a mean of 4 +/- 3.2 years. Ectopic atrial tachycardia recurred in one patient. A permanent pacemaker was implanted in two patients, one of whom also required reoperation for constrictive pericarditis. There were no operative deaths. Ectopic atrial tachycardia recurred in three (60%) of the five patients discharged on antiarrhythmic drug therapy during a mean follow-up interval of 6.4 +/- 4.3 years. There was one nonarrhythmic death. Map-guided surgery demonstrated long-term efficacy in abolishing symptoms in 9 of the 10 patients with ectopic atrial tachycardia. Results demonstrate that surgery is effective for patients with ectopic atrial tachycardias who are not easily treated with antiarrhythmic drugs.

Multidetector row computed tomography (MDCT) provides anatomical information about the kidney and other internal organs. Presently, the suitability of 64-channel MDCT to assess the kidney of healthy micropigs was evaluated. Morphological evaluations of the kidney and the major renal vessels of six healthy micropigs were carried out using MDCT, recording kidney volume and the diameter and length of renal arteries and veins. The mean diameters and lengths of the renal artery were 0.44 +/- 0.05 and 4.51 +/- 0.55 cm on the right side and 0.46 +/- 0.06 and 3.36 +/- 0.27 cm on the left side, respectively. The mean diameters and lengths of the renal vein were 1.44 +/- 0.52 and 4.22 +/- 1.29 cm on the right side and 1.38 +/- 0.17 and 5.15 +/- 0.87 cm on the left side, respectively. The mean volume of the right kidney was 79.3 +/- 14.5 mL and of the left kidney was 78.0 +/- 13.9 mL. The data presented in this study suggest that the MDCT offers a noninvasive, rapid, and accurate method for the evaluation of the renal anatomy in living kidney donors. It also provides sufficient information about extra-renal anatomy important for donor surgery and determination of organ suitability.

Heart failure is one of the most important complications of chronic kidney disease (CKD). However, few studies comprehensively investigated left ventricular (LV) structure and function in relation to 2 key CKD measures, estimated glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (ACR). Among 4175 ARIC (Atherosclerosis Risk in Communities) participants (aged 66-90 years during 2011-2013), we quantified the association of eGFR and ACR with echocardiogram parameters of LV mass, size, systolic function, and diastolic function. Adjusting for demographic variables, both CKD measures were significantly associated with most echocardiogram parameters. Additionally accounting for other potential confounders, we observed significantly higher LV mass index according to reduced eGFR (82.3 [95% confidence interval (CI), 77.6-87.0] g/m 2 for eGFR function, significant differences were observed for some parameters, particularly at eGFR function were robustly associated with albuminuria. These results have implications for pathophysiological processes behind cardiorenal syndrome and targeted cardiac assessment in patients with CKD. © 2017 The Authors.

Full Text Available A benign tumour is a non - cancerous growth that does not spread (metastasize to other parts of the body and is not usually life - threatening. Many researchers believe that most of the following types of kidney tumours are benign. However, others feel that some of these tumours have the potential to develop into renal cell carcinoma. There are no diagnostic tests that can confirm if a benign tumour has the potential to become cancerous. Benign tumours are sometimes found along with renal cell carcinoma when a removed kidney is examined by a pathologist. For these reasons, benign kidney tumours are treated like malignant tumours. In this case we have observed a male cadaver with a large tumour in the left kidney during our routine dissections of undergraduates .

Ectopic fascioliasis (EF) has direct and indirect effects on both humans and animals. The phenomenon of EF was individual cases in the period from 1950 up to the end of last century. From the period of 2000 up to 2006, plenty of researches were on EF in the developed and undeveloped countries. Nineteen EF cases infected with the immature and few with the mature worms were 13 females and 6 males. Three cases of lymphatic, pleural and breast fascioliasis reached the adults and laid their eggs in a lymph node in the cervical region pleural cavity and breast tissues. Until recent, knowledge about the ectopic fascioliasis pathway is little. Fasciola hepatica was the commonest species in most cases. The effect of fascioliasis might be direct to liver as ectopic foci or indirect on other organs due to the metabolites and secretory excretory products. All ages and both sexes were EF infected. Watercress topped the list of water plants born encysted metacercariae followed by lettuce, mint, and alfalfa. Nearly 24 million Egyptians at risk and about 800,000 were infected. On the global scale, about 180 million are at risk of infection.

Gene and protein expression of epidermal growth factor measured on the kidney 24 hours after irradiation correlates to late radiation damage

This study was designed to evaluate the proliferative response of epidermal growth factor (EGF) gene expression as an early indicator of late renal radiation damage. EGF gene expression was measured in the irradiated left kidney of C3H/HeSlc mice using RT-PCR 24 hours after radiation doses of 9, 12, or 15 Gy. In a second experiment, the same radiation doses were administered to the right kidney plus the lower half of the left kidney. The partly irradiated left kidneys were harvested and EGF gene expression was measured. The irradiated whole right kidneys were subjected to immunohistochemical staining for EGF protein. In a third experiment, 12 Gy was administered to the right kidney plus the lower half of the left kidney. The mice underwent left nephrectomy 24 hours after radiation, and the EGF gene expression in the kidney was correlated with the blood urea nitrogen (BUN) level representing late renal functional damage. EGF expression increased in 1 of 10 control mice and in 9 of 10 mice that received 15 Gy. The extent of increase of EGF was dependent on radiation dose. In mice having an increased BUN level after irradiation, 7 of 10 had EGF positive irradiated kidneys. All six mice whose BUN levels were unchanged had EGF-negative irradiated kidneys. EGF protein staining was observed in tubule cells only, not in glomerular cells. The amount of EGF protein staining correlated with radiation dose to some extent. EGF gene expression seems to be a very early indicator of late radiation damage to the kidney. (author)

Ectopic eruption of the first permanent molar is a relatively common occurence in the developing dentition. A range of treatment options are available to the clinician provided that diagnosis is made early. Non-treatment can result in premature exfoliation of the second primary molar, space loss and impaction of the second premolar. This paper will describe the management of ectopic first permanent molars, using clinical examples to illustrate the available treatment options. This paper is relevant to every general dental practitioner who treats patients in mixed dentition.

Bilateral multiple cystic kidney disease and renal cortical abscess in a Boerboel

Directory of Open Access Journals (Sweden)

2011-04-01

Full Text Available Cystic renal disease is rare in dogs and although infected renal cysts have been reported in humans, no report could be found in dogs. A 58 kg, 5-year-old, castrated, male Boerboel presented with weight loss, pyrexia, lethargy and vomiting, 20 months after an incident of haematuria was reported. The initial ultrasonographic diagnosis was bilateral multiple renal cysts of unknown aetiology. The cysts had significantly increased in size over the 20-month period and some contained echogenic specks which could be related to infection, normal cellular debris or haemorrhage. In both kidneys the renal contours were distorted (the left more than the right. The abnormal shape of the left kidney was largely due to multiple cysts and a large crescent-shaped septate mass on the cranial pole of the kidney. Aspirates of the septate mass were performed (left kidney and the cytology and culture were indicative of an abscess. It is suggested that the previous incident of haematuria provided a portal of entry for bacteria into the cysts resulting in renal cortical abscess formation.

Congenital cystic adenomatoid malformation (CCAM) is a rare pulmonary abnormality that results from aberrant fetal lung development. It about 4-26% of cases it can be associated with other congenital abnormalities. We describe a case of congenital cystic adenomatoid malformation 2 associated with polycystic kidney disease. The association of these two congenital malformations is exceptional. Only four similar cases have been reported in the literature. A 2-year-old girl was referred to the Department of Paediatric Surgery and Oncology Medical University of Lodz with pneumonia and left pneumothorax. For three weeks prior to referral the patient was treated with antibiotics. Chest x-ray revealed hyperinflation of left upper lobe with mediastinal shift to right. Computer tomographic scan of the lung revealed multiple cyst in the left upper lobe, left-site pneumothorax and mediastinal shift to the right. The patient underwent thoracotomy. Intraoperatively, multiple cysts in the left upper lobe were found and left upper lobectomy was performed. Histologic study was compatible with type 2 congenital cystic adenomatoid malformation. Ultrasound examination showed multilocular cysts in both kidneys. The dimensions of the cysts were: MWR4. 54x45x45 mm and 25x21x24 mm on the left and right sides, respectively. Significant increase in cyst size on the left side was observed. Ten months after first hospitalization resection of the cystic lower pole of the left kidney was performed. The presence of even a single renal cyst in a child with CCAM is an indication for further follow up examinations.

2009-08-01

The purpose of this study is to describe the anatomy and obtain echographic measurements of normal kidneys in brown lemurs (Eulemur fulvus). The anatomical findings show that brown lemur kidneys are comparable to those of rats except for an elongated papilla. The kidneys of 16 (7 females and 9 males) lemurs were examined with two-dimensional and power Doppler ultrasonography under general anesthesia. Morphometrically, the left and right kidney surface areas are comparable (3.29 and 3.51 cm(2)). Kidney area has a significant linear correlation with body weight. Echo-Doppler findings show that the mean renal arterial blood flow speeds for the left and right kidneys are comparable (0.70 and 0.73 m/s). However, flow speed is higher in the male (0.79 m/s) than in the female (0.60 m/s). The renal arterial diameters are between 1.0 and 1.8 mm. The fact that anesthesia can have hemodynamic effects on renal vasculature should be taken into consideration when assessing these echographic results.

This review summarises updated clinical guidelines produced by the Clinical Standards Committee of the Faculty of Dental Surgery, Royal College of Surgeons of England (FDSRCS). This guideline on the management of the palatally ectopic maxillary canine illustrates the information contained in the recently updated online version. The timely recognition of ectopic canines is important for the overall management of the dentition. This review illustrates five management strategies for ectopic permanent canines: interceptive treatment by extraction of the deciduous canine, surgical exposure and orthodontic alignment, surgical removal of the palatally ectopic permanent canine, auto-transplantation and no active treatment/leave and observe. The current available evidence for each of these management options has been evaluated and awarded a grade used by the Scottish Intercollegiate Guidelines Network.

Full Text Available In spite of the fact that urologic surgical techniques used by urologists are becoming more and more minimally invasive and easier because of developing technologies, surgical approaches for the urinary stones in kidneys with abnormal anatomy are still confusing. The objective of this article is to determine the treatment options in these kidneys. For this purpose, between 2005 and 2015, we retrospectively evaluated patients operated for urolithiasis with various congenital renal anomalies in five referral urology clinics in our country. Of the 178 patients (110 male, 60 female, 96 had horseshoe kidneys, 42 had pelvic ectopic kidneys (PEKs, and 40 had isolated rotation anomalies (IRAs of the kidney. We evaluated the patients for stone-free rate (SFR, mean operation time, mean hospitalization time, and complication rate. In horseshoe kidney, SFRs for retrograde intrarenal surgery (RIRS and percutaneous nephrolithotomy (PNL groups were 72.2% and 90%, respectively. In PEKs, these rates were 83.6% and 100% for RIRS and laparoscopic pyelolithotomy, respectively. SFRs in kidneys with IRA were 75% for RIRS and 83.3% for PNL. The mean operation time for RIRS and PNL groups in horseshoe kidney was 40.5±11.2 minutes and 74.5±19.3 minutes, respectively. In PEKs, these times were 52.1±19.3 minutes and 53.1±24.3 minutes for RIRS and laparoscopic pyelolithotomy, respectively. Mean operation time in kidneys with IRA was 48.7±14.4 minutes for RIRS and 53.2±11.3 minutes for PNL. Mean hospitalization times for RIRS and PNL groups in horseshoe kidneys were 1.4±0.7 days and 2.2±1.4 days, respectively. In PEKs, these times were 2.7±1.8 days and 1.9±0.4 days for RIRS and laparoscopic pyelolithotomy, respectively. Mean operation time in kidneys with IRA was 1.5±0.9 days for RIRS and 1.8±0.6 days for PNL. The results of our study showed that RIRS could be used in all of types of abnormal kidneys with small- and medium-sized renal calculi safely and

Alalade, Aderemi Olaoluwa; Smith, Fredrick John Ennis; Kendall, Charlotte Emma; Odejinmi, Funlayo

2017-11-01

Recent advances in ultrasonography and the use of other modalities including magnetic resonance imaging scans have led to the early and more accurate diagnosis of non-tubal ectopic pregnancies (NTE). As a result, the management of these pregnancies has evolved. This article addresses the management options currently available for NTE. While surgical management remains the mainstay of treatment for ovarian, abdominal and cornual ectopics, there is growing evidence that some of these can be managed medically. Many authors have utilised a combination of medical and surgical approaches in the management of cervical and caesarean section (CS) scar ectopic pregnancies with good outcome. The availability of dedicated early pregnancy units has further improved diagnosis and more importantly the follow-up care for these patients. The rarity of cases and the difficulty of ethically organising randomised trials for NTE remain a problem in formulating consistent pathways for optimum management of women with NTE.

Damage-induced ectopic recombination in the yeast Saccharomyces cerevisiae.

Kupiec, M; Steinlauf, R

1997-06-09

Mitotic recombination in the yeast Saccharomyces cerevisiae is induced when cells are irradiated with UV or X-rays, reflecting the efficient repair of damage by recombinational repair mechanisms. We have used multiply marked haploid strains that allow the simultaneous detection of several types of ectopic recombination events. We show that inter-chromosomal ectopic conversion of lys2 heteroalleles and, to a lesser extent, direct repeat recombination (DRR) between non-tandem repeats, are increased by DNA-damaging agents; in contrast, ectopic recombination of the naturally occurring Ty element is not induced. We have tested several hypotheses that could explain the preferential lack of induction of Ty recombination by DNA-damaging agents. We have found that the lack of induction cannot be explained by a cell cycle control or by an effect of the mating-type genes. We also found no role for the flanking long terminal repeats (LTRs) of the Ty in preventing the induction. Ectopic conversion, DRR, and forward mutation of artificial repeats show different kinetics of induction at various positions of the cell cycle, reflecting different mechanisms of recombination. We discuss the mechanistic and evolutionary aspects of these results.

Pinho, João; Braga, Carlos Galvão; Rocha, Sofia; Santos, Ana Filipa; Gomes, André; Cabreiro, Ana; Magalhães, Sónia; Ferreira, Carla

2015-02-01

To characterize atrial ectopic activity in patients with cryptogenic ischemic stroke (CIS) or transient ischemic attack (TIA) and determine its prognostic significance. Retrospective cohort study, in which 184 patients with CIS or TIA who had performed 24-hour Holter electrocardiogram were included. The median follow-up was 27.5 months. Baseline clinical and imagiologic characteristics, etiologic investigation results, and ischemic stroke and TIA recurrences information were collected. Number of atrial premature complexes (APCs) per hour was categorized as less than 10 APCs/hour, 10-30 APCs/hour, and more than 30 APCs/hour. Most of the patients had less than 10 APCs/hour (82.6%), 8.2% had 10-30 APCs/hour, and 9.2% had more than 30 APCs/hour. Patients with more than 30 APCs/hour had a greater median left atrium diameter than patients with 30 APCs/hour or less (42 mm vs. 38 mm; 95% confidence interval [CI], .50-7.00; P = .003). Annual recurrence rate of CIS or TIA was 2.9% in patients with less than 10 APCs/hour, 11.0% in 10-30 APCs/hour, and 22.6% in more than 30 APCs/hour (P = .001). More than 30 APCs/hour were independently associated with recurrence risk in multivariate survival analysis (hazard ratio, 3.40; 95% CI, 1.12-10.32; P = .030). In patients with CIS or TIA, frequent atrial ectopic activity (>30 APCs/h) was independently associated with increased risk of stroke or TIA recurrence. Further studies need to validate frequent atrial ectopic activity as a risk factor for recurrence in cryptogenic stroke and confirm its role as a predictor of occult atrial fibrillation.

1988-01-01

20 cases of ectopic thyroid gland were detected out of 5,261 thyroid scintigraphy from 1973. Except for 1 case, all cases were female. Considering of thyroid function, 11 cases were euthyroid and rest of 9 cases were hypothyroid function. Clinical symptom of hypothyroid cases were mainly retarded linear growth and high value of serum TSH and in case of euthyroid cases were sublingual tumor and fullness or tightness in throat. Thyroid scintigraphy is very useful to diagnose the sublingual tumor whether it is ectopic thyroid gland or not. In case of congenital hypothyroidism children, ectopic thyroid gland causing hypothyroidism is definitely diagnosed by thyroid scintigraphy. (author)

Fornazari, Vinicius Adami Vayego; Szejnfeld, Denis; Elito, Julio Júnior; Goldman, Suzan Menasce [Universidade Federal de São Paulo, São Paulo, SP (Brazil)

2015-07-01

The advent of interventional radiology enabled remarkable advances in diagnosis and treatment of several situations in obstetrics and gynecology. In the field of obstetrics, these advances include temporary occlusion of the iliac arteries to the management of placenta accreta and/or prior, arteriovenous fistulas after embolization of uterine curettage and management of ectopic uterine and extra-uterine pregnancies. The non-tubal ectopic pregnancy, either cervical, abdominal, ovarian or in a cesarean scar, often represents major therapeutic challenge, especially when exists a desire to maintain fertility. Despite the systemic methotrexate therapy and surgical resection of the ectopic gestational sac be the most used therapeutic options, the interventionist approach of non-tubal ectopic pregnancies, direct injection of methotrexate in the gestational sac and intra-arterial chemoembolization of uterine arteries constitute in the currently literature viable, safe, effective modalities with low morbidity, shorter hospital stay, and rapid clinical recovery. Because of little variety of materials used, and the increase in training of specialists in the area, the radiological intervention as a treatment option in ectopic pregnancies is financially viable and present considerable accessibility in the world and at most of Brazilian medical centers.

Rubio, C.A.; Eriksson, B.; Johnsson, L.

1983-01-01

Following segmental irradiation of the small bowel, 5 of 64 cats demonstrated ectopic intestinal glands in the submucosal tissue. In addition, one of these 5 cats had foci of abnormal glands in the muscularis mucosae. In 2 of the 5 animals, cellular polymorphism, nucleolar irregularity and loss of cellular polarity were present in irradiation-induced ectopic intestinal glands. The review of the literature indicates that intestinal irradiation may induce intestinal adenocarcinomas with metastatic growth. The possibility that ectopic intestinal glands are precancerous lesions in the irradiated cat is discussed. (Auth.)

To asses the frequency of ectopic pregnancy and to evaluate the relevance of the risk factors in a Medical Center, Kingdom of Saudi Arabia (KSA). This retrospective study was done in Royal Commission Medical Centre, Yanbu Industrial City, KSA over a period of four years, where the medical records of patients with the diagnosis of ectopic pregnancy were reviewed. Data was collected on initial presentation, chief medical complaints, socio demographic characteristics, past obstetrics and gynaecological history, history of previous surgeries (tubal, ovarian and/or uterine), history of infertility and use of ovulation induction and history of contraception was obtained. A total of 66 cases were included in the study. Results: The frequency of ectopic pregnancy was 0.58% .Mean age was 30 +- 4 years. Multiparous women were found to be more prone to ectopic pregnancy (64%).Most frequent gestational age was 6-8 weeks. Majority (37.8%) of the patients had previous medical induced or spontaneous abortion. 18% had previous pelvic surgery, 15% used different treatments for infertility including ovulation induction, Intrauterine Insemination (IUI), and In vitro Fertilization (IVF) and 9% of patients had history of ectopic pregnancy, 4.5% of patients had Intrautrine Contraceptive Device (IUCD) in situ. 3% of patients had uterine fibroids. Conclusion: Study has found that previous abortions are major etiological factor for ectopic pregnancy. Further more the other factors were IUCD use, previous pelvic surgeries, infertility, previous ectopic and induced conception cycles which may be the result of a previous pelvic infection that may cause tubal sequelae.

Full Text Available Spontaneous adrenal hemorrhage is an acute hemorrhage during pregnancy, which can be tragic for the mother and the baby. We report a unique spontaneous hemorrhage during pregnancy in a case with horseshoe kidney with separated adrenal, presented for the first time in the world. Computed tomography scan showed a horseshoe kidney fused with left normal kidney. Interestingly the adrenal gland was remained in right flank and separated from the horseshoe kidney, which prepares a probable physical stress for the hemorrhage. Diagnosis and surgery were done successfully and the case was fully recovered after several days.

Horseshoe kidney, also known as ren arcuatus is a congenital anomaly with incidence 1 in 500 people and it is more common in males. Usually this anomaly is asymptomatic and most of the cases are undiagnosed. This condition may contribute to upper Gl tract dyspeptic syndrome, abdominal discomfort, nephrolithiasis and frequent infections of the urinary system. Horseshoe kidney may lead to complications such as renal obstruction, recurrent inflammatory conditions and malignant diseases. The authors describe the case of 58y.o. male who had suffered acute renal failure. The patient presented with pain in the lumbar area and abode the symphysis, reduction of diuresis and fever 38° C. The laboratory findings showed slight anemic syndrome and preserved renal function. The US examination revealed low positioned right kidney with enlarged sizes and numerous cysts. The left kidney was visualized as gigantic hydronephrosis. Color and Power Doppler didn't show signal from the vessels. MRT of the abdomen and pelvis was performed with intravenous application of contrast medium. The examination showed horseshoe kidney with excessive hydro-nephrosis with massive dilation of the pyelocalyceal system and reduced parenchyma

Farideh Keypour

2013-06-01

Full Text Available Background: Tubal sterilization is the permanent and effective contraception method. This can be performed at any time, but at least half are performed in conjunction with cesarean or vaginal delivery and are termed puerperal. The most complication after tubal ligation is ectopic pregnancy. Ectopic pregnancy is the leading cause of maternal death in first trimester.Case presentation: We present a 33 years old woman gravida5, para4, all normal vaginal delivery, presented with complaints of delayed menstrual period, pelvic pain and spotting. She underwent tubal ligation for two times. For the first time she had puerperal Pomeroy tubal sterilization after third child delivery. Intra uterine pregnancy occurred three years later. One day after vaginal delivery of fourth child, she underwent post partum tubal ligation with the Parkland method. Tubal pregnancy occurred nine months later. Physical examination identified acute abdomen. Pelvic ultrasound showed no gestational sac in uterine cavity. The sac with fetal pole was in right adnexa. Beta-HCG was 2840mIU/ml. She underwent laparotomy. Surgical management included salpingectomy with cornual resection in both sides. The surgery identified Ectopic pregnancy.Conclusion: Any symptoms of pregnancy in a woman after tubal ligation must be investigated; an ectopic pregnancy should be excluded. Ectopic pregnancy must be considered, in any woman with lower abdominal pain, missed period and vaginal bleed-ing. Conception after tubal sterilization can be explained by fistula formation and re-canalization of fallopian tube.

2012-01-01

Full Text Available The storage of triglyceride (TG droplets in nonadipose tissues is called ectopic fat storage. Ectopic fat is associated with insulin resistance and type 2 diabetes mellitus (T2DM. Not the triglycerides per se but the accumulation of intermediates of lipid metabolism in organs, such as the liver, skeletal muscle, and heart seem to disrupt metabolic processes and impair organ function. We describe the mechanisms of ectopic fat depositions in the liver, skeletal muscle, and in and around the heart and the consequences for each organs function. In addition, we systematically reviewed the literature for the effects of diet-induced weight loss and exercise on ectopic fat depositions.

Increased circulating miR-21 levels are associated with kidney fibrosis.

Directory of Open Access Journals (Sweden)

François Glowacki

Full Text Available MicroRNAs (miRNAs are a class of noncoding RNA acting at a post-transcriptional level to control the expression of large sets of target mRNAs. While there is evidence that miRNAs deregulation plays a causative role in various complex disorders, their role in fibrotic kidney diseases is largely unexplored. Here, we found a strong up-regulation of miR-21 in the kidneys of mice with unilateral ureteral obstruction and also in the kidneys of patients with severe kidney fibrosis. In addition, mouse primary fibroblasts derived from fibrotic kidneys exhibited higher miR-21 expression level compared to those derived from normal kidneys. Expression of miR-21 in normal primary kidney fibroblasts was induced upon TGFβ exposure, a key growth factor involved in fibrogenesis. Finally, ectopic expression of miR-21 in primary kidney fibroblasts was sufficient to promote myofibroblast differentiation. As circulating miRNAs have been suggested as promising non-invasive biomarkers, we further assess whether circulating miR-21 levels are associated with renal fibrosis using sera from 42 renal transplant recipients, categorized according to their renal fibrosis severity, evaluated on allograft biopsies (Interstitial Fibrosis/Tubular Atrophy (IF/TA. Circulating miR-21 levels are significantly increased in patients with severe IF/TA grade (IF/TA grade 3: 3.0±1.0 vs lower grade of fibrosis: 1.5±1.2; p = 0.001. By contrast, circulating miR-21 levels were not correlated with other renal histological lesions. In a multivariate linear regression model including IF/TA grade and estimated GFR, independent associations were found between circulating miR-21 levels and IF/TA score (ß = 0.307, p = 0.03, and between miR-21 levels and aMDRD (ß = -0.398, p = 0.006. Altogether, these data suggest miR-21 has a key pathogenic role in kidney fibrosis and may represent a novel, predictive and reliable blood marker of kidney fibrosis.

Ectopic eruption of maxillary central incisor through abnormally thickened labial frenum: An unusual presentation

Directory of Open Access Journals (Sweden)

Neeraj Gugnani

2017-01-01

Full Text Available Ectopic eruption is a deviation from the normal eruption pattern, making the tooth erupt out of its normal position, and possibly causing resorption of adjacent primary teeth. A wide range of etiological factors may be responsible for ectopic eruption of the teeth, so their management depends on the correction of the established etiological factor. The present case report describes an unusual case of ectopically erupted central incisor encased within an abnormally thickened labial frenum, which was treated by orthodontic repositioning of the ectopically erupting tooth after frenectomy.

Introduction: Ectopic sphenoid sinus pituitary adenoma is a rare tumour originating from embryologic remnants of Rathke's pouch. Although it is considered a clinically benign neoplasm, necrosis is encountered in 25% of cases and it can invade adjacent bone structures. Aims: To establish clinical, radiological and histopathological features of ectopic sphenoid sinus pituitary adenoma. Material and methods: Analysis of three cases: two females and one man, aged 61-70. Results: One patient presented with a unilateral hearing loss, the other two with headache and vertigo. They all suffered from type 2 diabetes mellitus. Neurological examination revealed no abnormality. Radiological imaging showed a sphenoid sinus space-occupying soft-tissue lesion with bone erosion in 2 cases and empty sella in 2 patients whereas one had a normal pituitary gland. All were operated on via the transnasal approach. Total resection was achieved in one patient and subtotal in two; in two cases we observed intact sellar dura and in one intact sellar floor. Histopathology showed immunoreactivity for synaptophysin in all cases and cytokeratin in two. The Ki-67 index was less than 2%. Immunohistochemical staining demonstrated growth hormone cells in all cases whereas prolactin and adrenocorticotropin in two. The patients were discharged home in good condition with no neurological deficits. Conclusions: Ectopic sphenoid sinus pituitary adenoma should always be considered in differential diagnosis of sphenoid sinus lesion in the elderly, especially in coexistence with empty sella or type 2 diabetes mellitus. Since ectopic sphenoid sinus pituitary adenoma is a benign lesion, surgical removal is an effective treatment. .

Chronic sustained inflammation links to left ventricular hypertrophy and aortic valve sclerosis: a new link between S100/RAGE and FGF23.

Science.gov (United States)

Yan, Ling; Bowman, Marion A Hofmann

Cardiovascular disease including left ventricular hypertrophy, diastolic dysfunction and ectopic valvular calcification are common in patients with chronic kidney disease (CKD). Both S100A12 and fibroblast growth factor 23 (FGF23) have been identified as biomarkers of cardiovascular morbidity and mortality in patients with CKD. We tested the hypothesis that human S100/calgranulin would accelerate cardiovascular disease in mice subjected to CKD. This review paper focuses on S100 proteins and their receptor for advanced glycation end products (RAGE) and summarizes recent findings obtained in novel developed transgenic hBAC-S100 mice that express S100A12 and S100A8/9 proteins. A bacterial artificial chromosome of the human S100/calgranulin gene cluster containing the genes and regulatory elements for S100A8, S100A9 and S100A12 was expressed in C57BL/6J mice (hBAC-S100). CKD was induced by ureteral ligation, and hBAC-S100 mice and WT mice were studied after 10 weeks of chronic uremia. hBAC-S100 mice with CKD showed increased FGF23 in the heart, left ventricular hypertrophy (LVH), diastolic dysfunction, focal cartilaginous metaplasia and calcification of the mitral and aortic valve annulus together with aortic valve sclerosis. This phenotype was not observed in WT mice with CKD or in hBAC-S100 mice lacking RAGE with CKD, suggesting that the inflammatory milieu mediated by S100/RAGE promotes pathological cardiac hypertrophy in CKD. In vitro, inflammatory stimuli including IL-6, TNFα, LPS, or serum from hBAC-S100 mice up regulated FGF23 mRNA and protein in primary murine neonatal and adult cardiac fibroblasts. Taken together, our study shows that myeloid-derived human S100/calgranulin is associated with the development of cardiac hypertrophy and ectopic cardiac calcification in a RAGE dependent manner in a mouse model of CKD. We speculate that FGF23 produced by cardiac fibroblasts in response to cytokines may act in a paracrine manner to accelerate LVH and diastolic

Cushing's syndrome is caused by excessive adrenocorticotropic hormone (ACTH) secretion derived from pituitary corticotroph tumors (Cushing disease) or from non-pituitary tumors (ectopic Cushing's syndrome). Hypercortisolemic features of ectopic Cushing's syndrome are severe, and no definitive treatment for paraneoplastic ACTH excess is available. We aimed to identify subcellular therapeutic targets by elucidating transcriptional regulation of the human ACTH precursor POMC (proopiomelanocortin) and ACTH production in non-pituitary tumor cells and in cell lines derived from patients with ectopic Cushing's syndrome. We show that ectopic hPOMC transcription proceeds independently of pituitary-specific Tpit/Pitx1 and demonstrate a novel E2F1-mediated transcriptional mechanism regulating hPOMC We identify an E2F1 cluster binding to the proximal hPOMC promoter region (-42 to +68), with DNA-binding activity determined by the phosphorylation at Ser-337. hPOMC mRNA expression in cancer cells was upregulated (up to 40-fold) by the co-expression of E2F1 and its heterodimer partner DP1. Direct and indirect inhibitors of E2F1 activity suppressed hPOMC gene expression and ACTH by modifying E2F1 DNA-binding activity in ectopic Cushing's cell lines and primary tumor cells, and also suppressed paraneoplastic ACTH and cortisol levels in xenografted mice. E2F1-mediated hPOMC transcription is a potential target for suppressing ACTH production in ectopic Cushing's syndrome. © 2016 Society for Endocrinology.

Lande, Rachel; Dvorak, Laura; Gardiner, David W; Bahr, Anne

2015-01-01

A 6 yr old male Yorkshire terrier was presented for an ~6 yr history of progressive cough and dyspnea. Thoracic radiographs revealed a 6 cm diameter mass within the right caudal thorax. Thoracic ultrasound identified an intrathoracic mass ultrasonographically consistent with liver tissue and a chronic diaphragmatic hernia was suspected. Exploratory laparotomy was performed, but no evidence of a diaphragmatic hernia was identified. Thoracic exploration identified abnormal lung parenchyma. The accessory lung lobe was removed using a stapling devise near its base. The consolidated mass had the gross appearance of liver and was histologically identified as ectopic hepatic tissue. Ectopic hepatic tissue, unlike ectopic splenic and pancreatic tissue, is rare and generally has a subdiaphragmatic distribution. This solitary case report demonstrates that ectopic intrathoracic hepatic tissue should be considered a differential diagnosis for a caudal mediastinal mass.

1976-01-01

A simple technique has been developed to study the differential kidney function. It involves the intravenous injection of a product labelled with sup(99m)Tc, which possesses in vivo the characteristics of organo-mercurial derivatives. High-resolution kidney images are obtained, eliminating the excretion component which may be obtained with DTPA type products studying the glomerular filtration. The absolute quantitative uptake and the left kidney to right kidney activity ratio were measured successfully. This technique should find an increasing application in the evaluation of patients suffering from various kidney disorders including hypertension and acute pyelonephritis [fr

The aim of this study was to determine the frequency of anatomical variations of the colon associated with the kidney. A retrospective analysis was performed on 1000 consecutive abdominal computed tomography (CT) scans performed between July 2010 and September 2011. A line parallel to the horizontal plane was drawn through the posterior edge of each kidney at three renal levels: upper, middle and lower pole. The bowel between the psoas muscle and the kidney was determined as the interposition of the colon. The amount of perinephric fat was estimated and graded. The total number of patients undergoing CT scans was 1000 (male/female = 510/490). The mean age of patients was 42.2 years. Seventeen patients (1.7%) had retrorenal colon, of which 12 (1.2%) were on the left side, three (0.3%) on the right side and two (0.2%) were bilateral. Of these 17 cases, 11 were found at the lower, two at the middle and four at the upper pole of the kidney. There was grade I perirenal fat tissue in 13 and grade II in four cases. Interposition of the colon was detected in 32 (3.2%) patients, 30 (3%) on the right and two (0.2%) on the left. The grade of perirenal fat tissue in patients with colon interposition was as follows: 25 patients grade I, six patients grade II and one patient grade III. In accessing the lower pole of the kidney, especially on the left side, the risk of colonic injury should be taken into consideration during percutaneous procedures, regardless of the patient's age and gender.

Clinical Significance of Monitoring Serum β-HCG in the Conservative Treatment of Ectopic Pregnancy

Chen Xue

2010-01-01

To explore the clinical value of the serum β-HCG (human chorionic gonadotrophin) in the conservative treatment of ectopic pregnancy, the serum β-HCG levels in 118 patients with ectopic pregnancy were measured with RIA. The results showed that the serum β-HCG levels in patients with successful conservative treatment of ectopic pregnancy were all less than 200mIU/mL. The patients require a surgical treatment to reach <200mIU/mL serum β-HCG concentration were only 26.3%. There was significant difference between two groups (P<0.01). The monitoring of serum β-HCG was very useful in the diagnosis, the choice of treatment measures and the evaluation of conservative treatment effect of ectopic pregnancy. In the course of treatment of ectopic pregnancy, serum β-HCG is a good marker in determining the success or failure of treatment. (authors)

Mammary glands located in the vulvar region have been named as ectopic breast tissue or anogenital mammary glands by different authors. Literature on pathologies of ectopic breast tissue located in the vulvar region is rare. Most of the reports are about the malignancies arising from this ectopic tissue. We report a case of fibrocystic disease of the mammary glands in the vulva in a 25-year-old pregnant woman. Her disease was exaggerated during pregnancy. Ectopic breast tissue in the vulva is a rare entity and fibrocystic disease of this tissue has rarely been reported in the English literature. Copyright (c) 2004 S. Karger AG, Basel.

José Carlos Costa Baptista-Silva

Full Text Available OBJECTIVE: The ligation of the left renal vein (LLVR in man is a contraversial procedure in view of the risks of lesion to the renal parenchyma. With the objective of studying the morphologic and functional alterations caused by these lesions, we conducted experimental research with rats. MATERIAL AND METHODS: 64 male adult EPM1-WISTAR rats were used, divided into 8 groups - 4 for LLRV and four for control. Each LLRV group and corresponding control group were sacrificed progressively on the 7th, 15th, 30th and 60th day after the initial surgery. RESULTS: We found morphofunctional alterations only in animals that underwent LLRV in the four periods of sacrifice.The proteinuria creatinine in serum, testosterone in serum and serum corticosterone in serum showed practically no alteration in relation to the normal values for rats. Statistically significant severe histological lesions were found in the kidneys and testes of the LLRV groups. Lesions in the suprarenal glands were also present in these groups, but no sufficient to demonstrate statistical significance CONCLUSION: Based on these results we can conclude that the ligation of the left renal vein is a procedure of high risk in these animals.

2005-01-01

Background and purpose: In patients with macroadenoma, posterior pituitary high signal (PPHS) on T1-weighted magnetic resonance (MR) imaging is sometimes observed in an ectopic location. The present study compared incidences of ectopic PPHS before and after macroadenoma surgery using MR imaging, including dynamic MR imaging to ascertain whether this ectopic change is irreversible. Materials and methods: MR imaging was performed preoperatively in 111 cases of macroadenoma, and then repeated more than 1-year postoperatively in 47 patients. Enhancement of PPHS was assessed using dynamic MR imaging. Areas of enhanced hyperintensity were considered true PPHS, and the relationship between presence and location of true PPHS and adenoma volume was analyzed. Moreover, changes in the presence and location of true PPHS were ascertained among the patients who underwent postoperative follow-up MR imaging. Results: Preoperatively, PPHS was seen only in the normal location in 29 patients (Group A: 26.1%). High signal was detected only in an ectopic location in 58 patients, and early enhancement of this ectopic high signal was confirmed by dynamic MR imaging in 56 patients (Group B: 50.5%). No PPHS was observed in 24 patients (Group C: 21.6%). Adenoma volume was significantly greater for Group B than for Group A (p < 0.001). Among the Group B patients who underwent MR imaging postoperatively (n = 31), the location of PPHS was not changed, except for two patients in whom PPHS was absent. Postoperatively, PPHS was not observed in the normal location in any patient in the Group B. Conclusions: Greater volume of adenoma is associated with a higher incidence of ectopic PPHS, and the ectopic change is irreversible

Dioctophyma renale (D. renale), or giant kidney worms, are the largest nematodes that infect mammals. Approximately 20 cases of human infection have been reported. We present a case of a 71-year-old man with a recent history of unintentional weight loss and painless haematuria, passing elongated erythematous tissue via his urethra. CT revealed a left renal mass with pulmonary nodules and hepatic lesions. On microscopy, the erythematous tissue passed was identified as D. renale. On subsequent renal biopsy, pathology was consistent with renal cell carcinoma. This is the first reported case of concomitant D. renale infection and renal cell carcinoma, and the second reported case of D. renale infection of the left kidney alone. 2016 BMJ Publishing Group Ltd.

Endoscopic Urinary Diversion As Initial Management of Symptomatic Obstructive Ectopic Ureter in Infants

Directory of Open Access Journals (Sweden)

Ruben Ortiz

2017-09-01

Full Text Available AimDefinitive surgery of ectopic ureter in infants is challenging. We propose an endoscopic urinary diversion (EUD as a novel surgical technique in the initial management of symptomatic obstructive ectopic ureter.Patients and methodsSixteen obstructive ectopic ureters (14 patients were initially treated by EUD between 2006 and 2015. All patients had urinary tract dilatation worsening at preoperative US scans and at least two febrile urinary tract infection (UTI or urinary sepsis despite antibiotic prophylaxis. Ectopic ureter was confirmed by cystoscopy. When ectopic meatus was not found, EUD consisted in the creation of a transurethral neo-orifice (TUNO performed by needle puncturing of the ureterovesical wall, under fluoroscopic and ultrasound control. If ectopic meatus was identified in the posterior urethra, “intravesicalization procedure” was done opening the urethral–ureteral wall to create a new ureteral outlet into the bladder.ResultsEUD was done at a median age of 3.5 months (0.5–7 with median follow-up of 48 months (24–136. TUNO was performed in six patients and “intravesicalization” in eight patients. Significant differences were observed in ureteral diameter and anteroposterior pelvis diameter before and after endoscopic treatment (p < 0.005. Initial renal function was preserved in all cases. Postoperative complications were UTI in four patients and TUNO stenosis in one patient, treated by endoscopic balloon dilation. Definitive treatment was further individualized in each patient after 1 year of life.ConclusionEUD is a feasible and safe less-invasive technique in the initial management of symptomatic obstructive ectopic ureter. It allows an adequate ureteral drainage preserving renal function until definitive repair if necessary and does not invalidate other surgical options in case of failure or future definitive treatments.

Multiple Ectopic Hepatocellular Carcinomas Arising in the Abdominal Cavity

Directory of Open Access Journals (Sweden)

Toru Miyake

2012-09-01

Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

Full text: Objective: Localizing of ectopic parathyroid adenomas, mainly of those located at large distal from cervical anterior region is very difficult by imaging methods, due to reduced number of specific imaging features. Material and Method: We present the case of a patient with hyper functional parathyroid tissue located in anterior mediastinum, detected by using nuclear medicine techniques (planar imaging and 99-m-Tc-Sestamibi) and CT with contrast agent. Results and discussions: Parathyroid scintigraphic imaging with metabolic radiotracer (99-m-Tc-Sestamibi) have shown normal uptake in thyroid area but shown a focal area with increased uptake in anterior mediastinum, on early and late planar images, transverse, sagittal and coronal SPECT images and on 3D reconstruction, suggesting the presence of ectopic parathyroid adenoma, which correlated with symptoms and laboratory analysis (high-modified values of PTH, Urinary Ca, Normal serum Ca). Thyroid ultrasonography normal aspect. CT native and with contrast agent showed remnant thymic tissue (?), pre-aortic anterior mediastinum nodule; normal thyroid aspect. Correlating this data was established the diagnosis of primary hyperparathyroidism due to mediastinum ectopic parathyroid adenoma. Surgical intervention showed intra thymic nodular process, well-defined, with 1 cm diameter in right thymic lobe. Thymectomy was realized. AP exam confirmed diagnosis of parathyroid adenoma. Post surgical determination of serum, urinary and PTH showed normalization of these values. Conclusions: In assessing parathyroid adenomas, mainly with ectopic location, combination of morphologic and functional techniques allows an accurate location of these processes, ensuring a correct diagnosis, adequate therapeutical management and optimal long-term prognosis for patient.

Materials and methods: In all, 137 healthy participants (mean age 42.8 ± 14.7 years; age range 16–75 years) comprising 68 male and 69 female participants were enrolled. Three Tesla echo-planar diffusion-weighted imaging (DWI) of bilateral kidneys was performed and ADC values were measured in the cortex, medulla, and whole parenchyma. Pearson correlation analysis and linear regression were performed to determine the associations between the ADC values in each region and age. Effects of age and gender on ADC values were analysed using two-factor analysis of variance (ANOVA). The paired-samples t-test was established to compare the ADC values between left and right kidneys. Results: ADC values were significantly higher in the young group (≤50 years) than in the old group (>50 years), and correlated inversely with the age in all regions. Male participants had higher ADC values than female participants in all regions except left medulla. Two-factor ANOVA of age × gender showed no significant interactions between the variables age and gender were found. No significant differences in ADC values between left and right kidneys were observed. Conclusion: Renal ADC values are age- and gender-dependent, and show no significant difference between left and right kidneys. Age- and gender-related effects should be taken into consideration in future renal DWI studies when using normal ADC values from health controls. - Highlights: • Renal apparent diffusion coefficient (ADC) values decrease with ageing. • Men tend to have higher renal ADC values than women. • Bilateral kidneys seem to have no significantly different ADC values

Congenital abnormalities of the kidney and urinary tract (CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis (bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number (agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography (US) is typically the first imaging performed as it is easily available, non-invasive and radiation free used both antenatally and postnatally. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.

Laparoscopic surgery has rapidly expanded in clinical practice replacing conventional open surgery over the last three decades. Laparoscopic donor nephrectomy has been favored due to its multiple benefits. The aim of this study was to explore the safety and feasibility of kidney transplantation by a laparoscopic technique in a pig model. The study was approved by the university animal ethics committee. Eight female pigs (Sus Scrofra, weighing 45-50 kg) were divided into 2 groups: group I included 4 animals that underwent laparoscopic kidney orthotopic transplantation on the left side. The right kidney was remained functional in situ. The pigs recovered and were observed for 1 week. In the 4 hosts group II pigs underwent a laparoscopic kidney transplantation on the left side. With simultaneous clipping of the right ureter. After recovery, the pigs were observed for 4 weeks. A laparotomy for examination was performed prior to euthanasia. All 4 group I pigs survived for 1 week. The laparotomy showed normal graft perfusion with wall patent renal artery and vein as well as satisfactory urine output upon transection of ureter in 3 hosts. Renal artery stenosis occurred in one pig. In The Immediate kidney graft function was achieved in 3 group II pigs. The fourth died following extubation due to laryngospasm despite a functional graft. The average creatinine levels were 195.5 μmol/L on day 3; 224.5 μmol/L at week 1; 127 μmol/L at week 2; 182.7 umol/L at week 3; and 154.7 umol/L at week 4. Laparoscopic kidney transplantation was feasible and safe in a pig model with immediate graft function. This study will provide further evidence to support application of laparoscopic technique to human kidney transplant. Copyright © 2013 Elsevier Inc. All rights reserved.

To illustrate a laparoscopic technique for the resection of cesarean scar ectopic pregnancy, associated with isthmocele repair. Case report (Canadian Task Force classification III). A tertiary referral center in Strasbourg, France. Cesarean scar pregnancy is a rare form of ectopic pregnancy. The major risk of this type of pregnancy is the early uterine rupture with massive, sometimes life-threatening, bleeding. Thus, active management of these pregnancies starting immediately after diagnosis is crucial. Therapeutic options can be medical, surgical, or a combination. Numerous case reports or case series can be found in the literature, but there are few clinical studies, which are difficult to conduct because of case rarity and inconclusiveness. A 2016 meta-analysis that included 194 articles published between 1978 and 2014 (126 case reports, 45 cases series, and 23 clinical studies) concluded that hysteroscopy or laparoscopic hysterotomy seems to be the best first-line approach to treating cesarean scar ectopic pregnancy, with uterine artery embolization reserved for significant bleeding and/or a high suspicion index for arteriovenous malformation [1]. There is no consensus on the treatment of reference, however. The case involves a 38-year-old primiparous women who underwent a cesarean section delivery in 2010 and who was diagnosed by ultrasound scan at 7 weeks gestation with cesarean scar ectopic pregnancy, which was confirmed by pelvic magnetic resonance imaging. The patient initially received medical treatment with 2 intramuscular injections of methotrexate and one local intragestational injection of KCl. Her initial human chorionic gonadotropin (hCG) level was 82 000 IU/L. Rigorous weekly biological and ultrasound monitoring revealed an involution of the ectopic pregnancy associated with decreasing hCG. No bleeding or infectious complications occurred during this period. After 10 weeks of monitoring, her hCG had stabilized at 300 IU/L, and a residual image

ACTH overexpressing pituitary hyperplasia in a patient with ectopic ACTH-syndrome due to carcinoid of the lung

Full Text Available Ectopic ACTH-syndrome is the most diagnostically challenging  variant of endogenous hypercortisolism. Particularly difficult differential diagnosis of this syndrome is from Cushing's disease (CD, as currently there is no single test sufficiently accurate to differentiate accurately ectopic ACTH production from the pituitary. The main functional tests are based on the fact that the vast majority of ectopic ACTH production is autonomous and suppresses one from pituitary. But in some cases this is not observed, and then the data obtained all necessary laboratory and instrumental research evidence in favor of central genesis of CD in a patient with ACTH ectopic secretion, which can lead to inappropriate treatment. If you confirm the ectopic ACTH-syndrome, it may take quite a long time of searching for the pathological focus, as there is no sufficiently precise imaging and diagnostic method for determining the localization of ectopic source of ACTH production. Thus, the differential diagnosis of ACTH-dependent hypercortisolism and localization of the ectopic tumor is the cornerstone of early and radical treatment of patients. We present a difficult clinical case of a patient having a pituitary hyperplasia with excessive ACTH expression with primary ectopic ACTH syndrome caused by lung carcinoid.

A left retrocaval ureter is an extremely rare congenital anomaly, in which the left ureter passes behind the left inferior vena cava (IVC). The compression of the ureter between the IVC and the vertebrae results in a progressive hydronephrosis. Recently, the left kidney with a retrocaval ureter was detected on CT urographic images in a living-related donor and achieved a good outcome after allograft transplantation. We report the CT urographic findings of a left retrocaval ureter and the short-term outcome of allograft transplantation.

Uterine didelphys with obstructed hemivagina and ipsilateral renal anomalies is a rare congenital malformation of the female urogenital tract. While the urinary anomalies almost always involve renal agenesis, we report a rare case of a 17-year-old girl with the malformation associated with ectopic ureteral insertion into the obstructed hemivagina, which was diagnosed preoperatively by MR imaging. To the best of our knowledge, preoperative MR imaging diagnosis of the ectopic ureter associated with this syndrome has not been previously reported. Accurate preoperative diagnosis of ectopic ureteral insertion associated with this syndrome is important for surgical planning. (orig.)

Ectopic thyroid tissue an uncommon condition results from abnormal migration of the primitive thyroid bud. This may be the only functional thyroid. Ectopic thyroid tissue may sometimes coexist with the eutopic thyroid gland. Hyperthyroidism in association with ectopic thyroid tissue is very uncommon. We report a rare case of simultaneous involvement of ectopic and eutopic thyroid tissue in a married women of 35 years who was referred to our department for a technetium 99m thyroid scan. Coexisting ectopic and eutopic thyroid tissue due to identical histology may have similar response to various stimulatory and inhibitory factors like hormones and immunoglobulin's. Iodine-131 is an easy to administer and effective treatment for patients with simultaneous Graves’ disease in the ectopic and eutopic thyroid tissues

PurposeTo address technical feasibility and clinical outcome of transcatheter embolotherapy with N-butyl cyanoacrylate (NBCA) for bleeding ectopic varices.MethodsThe institutional review board approved this retrospective study and waived informed consent. From January 2004 to June 2013, a total of 12 consecutive patients received transcatheter embolotherapy using NBCA for bleeding ectopic varices in our institute. Clinical and radiologic features of the endovascular procedures were comprehensively reviewed.ResultsPreprocedural computed tomography images revealed ectopic varices in the jejunum (n = 7), stoma (n = 2), rectum (n = 2), and duodenum (n = 1). The 12 procedures consisted of solitary embolotherapy (n = 8) and embolotherapy with portal decompression (main portal vein stenting in 3, transjugular intrahepatic portosystemic shunt in 1). With regard to vascular access, percutaneous transhepatic access (n = 7), transsplenic access (n = 4), and transjugular intrahepatic portosystemic shunt tract (n = 1) were used. There was no failure in either the embolotherapy or the vascular accesses (technical success rate, 100 %). Two patients died within 1 month from the procedure from preexisting fatal medical conditions. Only one patient, with a large varix that had been partially embolized by using coils and NBCA, underwent rebleeding 5.5 months after the procedure. The patient was retreated with NBCA and did not undergo any bleeding afterward for a follow-up period of 2.5 months. The remaining nine patients did not experience rebleeding during the follow-up periods (range 1.5–33.2 months).ConclusionTranscatheter embolotherapy using NBCA can be a useful option for bleeding ectopic varices.

Each kidney is supplied by a single renal artery originating from abdominal aorta. Since there are lots of renal surgeries happening now-a-days, it becomes mandatory for the surgeons to understand the abnormality and variations in the renal vasculature. To study the variations in the branching pattern of renal artery for the presence of early division and accessory renal artery in Indian kidney donors using CT angiography. The CT angiogram images of 100 normal individuals willing for kidney donation were analysed for early divisions and occurrence of accessory renal artery. A 51% of kidney donors showed variation in the renal artery. Out of 51% variations 38 individuals had accessory renal artery and 13 individuals had early division of renal artery. The distribution of accessory renal artery was equal on both sides (13% on right and left) and 12% of individuals had accessory renal artery on both sides. Out of 13% earlier divisions, 5% was on right side, 7% was on left side and 1% was on both sides. This study concludes that 51% of kidney donors had renal artery variations. Hence, awareness of variations by evaluating the donors is a must before renal transplantation, urological procedures and angiographic interventions.

Widespread ectopic expression of olfactory receptor genes

2006-05-01

Full Text Available Abstract Background Olfactory receptors (ORs are the largest gene family in the human genome. Although they are expected to be expressed specifically in olfactory tissues, some ectopic expression has been reported, with special emphasis on sperm and testis. The present study systematically explores the expression patterns of OR genes in a large number of tissues and assesses the potential functional implication of such ectopic expression. Results We analyzed the expression of hundreds of human and mouse OR transcripts, via EST and microarray data, in several dozens of human and mouse tissues. Different tissues had specific, relatively small OR gene subsets which had particularly high expression levels. In testis, average expression was not particularly high, and very few highly expressed genes were found, none corresponding to ORs previously implicated in sperm chemotaxis. Higher expression levels were more common for genes with a non-OR genomic neighbor. Importantly, no correlation in expression levels was detected for human-mouse orthologous pairs. Also, no significant difference in expression levels was seen between intact and pseudogenized ORs, except for the pseudogenes of subfamily 7E which has undergone a human-specific expansion. Conclusion The OR superfamily as a whole, show widespread, locus-dependent and heterogeneous expression, in agreement with a neutral or near neutral evolutionary model for transcription control. These results cannot reject the possibility that small OR subsets might play functional roles in different tissues, however considerable care should be exerted when offering a functional interpretation for ectopic OR expression based only on transcription information.

Human fascioliasis with Fasciola species occurs worldwide and is most common among rural people who tend sheep and eat uncooked water vegetables, particularly watercress. The natural history of the acute phase begins with ingestion of metacercariae encysted on various kinds of aquatic vegetation such as watercress. Fascioliasis primarily involves the liver, bile ducts, gallbladder, and occasionally ectopic sites. We describe herein a case of ectopic fascioliasis. This uncommon form of disease was peritonitis; both visceral and parietal peritoneal layers were affected with the formation of multiple nodules and ascites.

Approximately 100 cases of collecting duct carcinoma have been reported in the medical literature. We herein report on a case of collecting duct carcinoma of the kidney in a 75-year-old patient. The abdominal sonography depicted a relatively poorly defined 7x6 cm sized, isoechoic mass lesion, as compared to the normal parenchyma, at the left kidney lower pole and the affected kidney showed preservation of the reniform shape. CT revealed a heterogeneous poorly defined low-attenuation mass that was mainly located in the medulla with involvement of the cortex and the lower half of the renal pelvis. Retrograde ureter opyelography showed a filling defect at the lower renal pelvis and severe narrowing of the left proximal ureter. We initially thought this lesion was invasive transitional cell carcinoma. Subsequent surgery confirmed a collecting duct carcinoma

2013-01-01

To evaluate the relationship between anthropometric measurements and renal length and volume measured with ultrasound in Korean children who have morphologically normal kidneys, and to create simple equations to estimate the renal sizes using the anthropometric measurements. We examined 794 Korean children under 18 years of age including a total of 394 boys and 400 girls without renal problems. The maximum renal length (L) (cm), orthogonal anterior-posterior diameter (D) (cm) and width (W) (cm) of each kidney were measured on ultrasound. Kidney volume was calculated as 0.523 x L x D x W (cm 3 ). Anthropometric indices including height (cm), weight (kg) and body mass index (m 2 /kg) were collected through a medical record review. We used linear regression analysis to create simple equations to estimate the renal length and the volume with those anthropometric indices that were mostly correlated with the US-measured renal sizes. Renal length showed the strongest significant correlation with patient height (R2, 0.874 and 0.875 for the right and left kidneys, respectively, p < 0.001). Renal volume showed the strongest significant correlation with patient weight (R2, 0.842 and 0.854 for the right and left kidneys, respectively, p < 0.001). The following equations were developed to describe these relationships with an estimated 95% range of renal length and volume (R2, 0.826-0.884, p < 0.001): renal length = 2.383 + 0.045 x Height (± 1.135) and = 2.374 + 0.047 x Height (± 1.173) for the right and left kidneys, respectively; and renal volume 7.941 + 1.246 x Weight (± 15.920) and = 7.303 + 1.532 x Weight (± 18.704) for the right and left kidneys, respectively. Scatter plots between height and renal length and between weight and renal volume have been established from Korean children and simple equations between them have been developed for use in clinical practice.

Localization of Presynaptic Plasticity Mechanisms Enables Functional Independence of Synaptic and Ectopic Transmission in the Cerebellum

Directory of Open Access Journals (Sweden)

Katharine L. Dobson

2015-01-01

Full Text Available In the cerebellar molecular layer parallel fibre terminals release glutamate from both the active zone and from extrasynaptic “ectopic” sites. Ectopic release mediates transmission to the Bergmann glia that ensheathe the synapse, activating Ca2+-permeable AMPA receptors and glutamate transporters. Parallel fibre terminals exhibit several forms of presynaptic plasticity, including cAMP-dependent long-term potentiation and endocannabinoid-dependent long-term depression, but it is not known whether these presynaptic forms of long-term plasticity also influence ectopic transmission to Bergmann glia. Stimulation of parallel fibre inputs at 16 Hz evoked LTP of synaptic transmission, but LTD of ectopic transmission. Pharmacological activation of adenylyl cyclase by forskolin caused LTP at Purkinje neurons, but only transient potentiation at Bergmann glia, reinforcing the concept that ectopic sites lack the capacity to express sustained cAMP-dependent potentiation. Activation of mGluR1 caused depression of synaptic transmission via retrograde endocannabinoid signalling but had no significant effect at ectopic sites. In contrast, activation of NMDA receptors suppressed both synaptic and ectopic transmission. The results suggest that the signalling mechanisms for presynaptic LTP and retrograde depression by endocannabinoids are restricted to the active zone at parallel fibre synapses, allowing independent modulation of synaptic transmission to Purkinje neurons and ectopic transmission to Bergmann glia.

Ectopic molar pregnancy is extremely rare, and preoperative diagnosis is difficult. Our literature search found only one report of molar pregnancy diagnosed preoperatively. Moreover, there is no English literature depicting magnetic resonance image (MRI) findings of ectopic molar pregnancy. We report a case of ectopic molar pregnancy preoperatively diagnosed using MRI. A literature review of 31 cases of ectopic molar pregnancy demonstrated that lesions have been found in the fallopian tube (19 cases, 61%), ovary (5 cases, 16%), cornu (3 cases, 10%), peritoneum (2 cases, 6%), uterine cervix (1 case, 3%), and cesarean scar (1 case, 3%). Abdominal pain and abnormal vaginal bleeding were reported in 70% and 61% of the patients, respectively. Twenty-one cases (67%) presented with rupture and hemoperitoneum. All patients underwent surgical resection or dilatation and curettage. Methotrexate therapy was performed in one case because residual trophoblastic tissue was suspected. A second operation was performed in one case of ovarian molar pregnancy because serum hCG levels increased again after primary focal ovarian resection. No patients developed metastatic disease or relapsed. These findings suggest the prognosis of ectopic molar pregnancy to be favorable.

A literature review of 31 cases of ectopic molar pregnancy demonstrated that lesions have been found in the fallopian tube (19 cases, 61%, ovary (5 cases, 16%, cornu (3 cases, 10%, peritoneum (2 cases, 6%, uterine cervix (1 case, 3%, and cesarean scar (1 case, 3%. Abdominal pain and abnormal vaginal bleeding were reported in 70% and 61% of the patients, respectively. Twenty-one cases (67% presented with rupture and hemoperitoneum. All patients underwent surgical resection or dilatation and curettage. Methotrexate therapy was performed in one case because residual trophoblastic tissue was suspected. A second operation was performed in one case of ovarian molar pregnancy because serum hCG levels increased again after primary focal ovarian resection. No patients developed metastatic disease or relapsed. These findings suggest the prognosis of ectopic molar pregnancy to be favorable.

The accuracy of repeated sonographic and urographic kidney length measurements in kidney size evaluation was investigated in 80 children 0 to 14 years of age, mean age 4.5 years. At sonography 250 kidney lengths were compared. A difference of 0 to 1.0 cm in repeated length measurement was considered to be good accuracy and 94 per cent of right and 96 per cent of left kidney length were found within this interval-a better result than for urography with 76 per cent of repeated right kidney and 79 per cent of kidney lengths within the same interval (94 lengths). Both methods display a variation of kidney lengths which may lead to under- and overestimation of kidney size and growth. The investigation thus indicates good accuracy for repeated sonographic kidney size assessment which should be repeated often enough to estabilish a growth chart displaying the trend rather than rely too much on single measurements. Sonography can be highly recommended as a convenient and harmless alternative to urography. (orig.)

2016-10-01

Full Text Available BACKGROUND Ectopic pregnancies are increasing in number and proportions. Real increase and better detection methods are contributing for this rise. All the cases diagnosed now are not surgical emergencies. Medical management and expectant line of management are possible. Revised clinical guidelines are there for the selection of cases for nonsurgical management. Knowledge about the risk factors is good for prophylaxis and to have a high suspicion about ectopic pregnancy in high-risk individuals. Knowing the success rate is absolutely essential for counselling before starting the therapy. Aim of the study- 1. To study the risk factor profile of ectopic pregnancies and to compare them with the old data of the study setting. 2. To follow up the cases receiving nonsurgical treatment and to assess the success rate. MATERIALS AND METHODS Study Setting- Department of Obstetrics and Gynaecology, Government Medical College, Kottayam. It is a tertiary care centre with 1500 beds and catering for the population of five districts of Kerala. Study Design- Observational Study Study Period- This study was completed by eighteen months from April 2014 to September 2015. RESULTS 219 cases of ectopic pregnancies were diagnosed during the study period. The ratio of this number with the total number of deliveries during that period is 3.48% and this is three times higher than that of the ratio twenty years ago (1.23%. Risk factor profile is also showing changes over this period. 15.1% had medical treatment and 11% had expectant line of therapy. Success rates are 87.87% and 95.65%, respectively. CONCLUSIONS Incidence and detection of ectopic pregnancies are increasing and the risk factor profile is changing. In properly selected cases, the success of nonsurgical management is excellent.

The mammalian kidney consists of an array of tubules connected to a ductal system that collectively function to control water/salt balance and to remove waste from the organisms' circulatory system. During mammalian embryogenesis, three kidney structures form within the intermediate mesoderm. The two most anterior structures, the pronephros and the mesonephros, are transitory and largely non-functional, while the most posterior, the metanephros, persists as the adult kidney. We have explored the mechanisms underlying regional specific differentiation of the kidney forming mesoderm. Previous studies have shown a requirement for Hox11 paralogs (Hoxa11, Hoxc11 and Hoxd11) in metanephric development. Mice lacking all Hox11 activity fail to form metanephric kidney structures. We demonstrate that the Hox11 paralog expression is restricted in the intermediate mesoderm to the posterior, metanephric level. When Hoxd11 is ectopically activated in the anterior mesonephros, we observe a partial transformation to a metanephric program of development. Anterior Hoxd11(+) cells activate Six2, a transcription factor required for the maintenance of metanephric tubule progenitors. Additionally, Hoxd11(+) mesonephric tubules exhibit an altered morphology and activate several metanephric specific markers normally confined to distal portions of the functional nephron. Collectively, our data support a model where Hox11 paralogs specify a metanephric developmental program in responsive intermediate mesoderm. This program maintains tubule forming progenitors and instructs a metanephric specific pattern of nephron differentiation.

Left ventricular hypertrophy is common and is associated with cardiovascular events and death among patients with known chronic kidney disease. However, the link between reduced glomerular filtration rate (GFR) and left ventricular mass index (LVMI) remains poorly explored among young and middle-aged adults with preserved kidney function. In this study, we examined the association of cystatin C-based estimated GFR (eGFRcys) and rapid decline in eGFR with subsequent LVMI. Observational study. We included 2,410 participants from the Coronary Artery Risk Development in Young Adults (CARDIA) cohort with eGFRcys > 60mL/min/1.73m(2) at year 15 and who had an echocardiogram obtained at year 25. eGFRcys at year 15 and rapid decline in eGFRcys (defined as >3% per year over 5 years from years 15 to 20). LVMI measured at year 25. We adjusted for age, sex, race, diabetes, body mass index, low- and high-density lipoprotein cholesterol levels, cumulative systolic blood pressure, and albuminuria. Mean age was 40±4 (SD) years, 58% were women, and 43% were black. After 10 years of follow-up, mean LVMI was 39.6±13.4g/m(2.7). Compared with eGFRcys > 90mL/min/1.73m(2) (n = 2,228), eGFRcys of 60 to 75mL/min/1.73m(2) (n = 29) was associated with 5.63 (95% CI, 0.90-10.36) g/m(2.7) greater LVMI (P = 0.02), but there was no association of eGFRcys of 76 to 90mL/min/1.73m(2) (n = 153) with LVMI after adjustment for confounders. Rapid decline in eGFRcys was associated with higher LVMI compared with participants without a rapid eGFRcys decline (β coefficient, 1.48; 95% CI, 0.11-2.83; P = 0.03) after adjustment for confounders. There were a limited number of participants with eGFRcys of 60 to 90mL/min/1.73m(2). Among young and middle-aged adults with preserved kidney function, eGFRcys of 60 to 75mL/min/1.73m(2) and rapid decline in eGFRcys were significantly associated with subsequently higher LVMI. Further studies are needed to understand the mechanisms that contribute to elevated

We describe the 2D reformatted and 3D volume rendered images by MDCT in a patient with an episode of acute bleeding from the colonic stoma. This case indicates that the 2D reformatted and 3D volume rendered images are useful to detect this rare complication of portal hypertension, and they help to tailor adequate treatment for the patients with bleeding from stomal varices. Ectopic varices are an uncommon cause of gastrointestinal hemorrhage, but they account for up to 5% of all variceal bleedings (1). Bleeding from stomal varices has been reported in up to 20% of the patients suffering with chronic liver failure with permanent stoma (2). However, the diagnosis of stomal varices is difficult because bleeding from stoma may also be associated with lower gastrointestinal bleeding. To the best of our knowledge, the 2D reformatted and 3D volume rendered images by MDCT for visualization of ectopic stomal varices have not been previously reported in the medical literature.

Ectopic pregnancy (EP) is a major problem in obstetrics as there is evidence of increasing incidence throughout the world. It is an important cause of maternal morbidity and mortality. In Pakistan, the care seeking behaviour among female is limited that makes female vulnerable to die due to complication of ectopic pregnancy. The aim of this study is to determine the frequency of tubal rupture in ectopic pregnancy in Pakistani patients. Method: In this cross-sectional study data pertaining to age, gestational age, parity and duration of presenting symptoms were collected and analysed. Result: 80 patients were diagnosed to have ectopic pregnancy. The frequency of tubal rupture was 91.25%. It is encountered significantly more often in women with age of 26 years. More tubal rupture is found in patient with low parity, in which the frequency of tubal rupture is up to 100% and decrease up to 78.6% with increasing parity up to four. Furthermore, it is noted that increase in gestational age from 8 weeks to 10 weeks caused an increase in frequency of tubal rupture from 80 to 100% respectively. It is also noted that earlier the patient presents the lesser is the frequency of tubal rupture, as compared to late presentation beyond 3-4 days which make frequency up to 95%. Conclusion: Tubal rupture is still common cause of maternal morbidity and mortality, and is still a major challenge in gynaecological practice. Creating awareness amongst midwives and GPs regarding early diagnosis can contribute to decrease the mortality, morbidity and fertility loss related to EP. (author)

The gross anatomy and morphometry of the kidney and renal arteries were studied in the strains of laboratory rat: Sprague-Dawley (Sp) and Wistar (W) rats. Total of 106 three-dimensional endocasts of the intrarenal arteries of kidney that were prepared using standard injection-corrosion techniques were examined. A single renal artery was observed in 100% of the cases. The renal arteries were divided into a dorsal and a ventral branch. The dorsal and ventral branches were divided into two branches, the cranial and caudal branch. Renal arteries were classified into types I and II, depending on the cranial and caudal branches and their made of branching. The present study also showed that the right kidney was slightly heavier than the left one and that the kidney of the male was generally larger than that of the female. The mean live weights of the Sprague-Dawley and Wistar rats were found to be 258.26 ± 5.9 and 182.4 ± 19.05 g, respectively. The kidney weights were significantly correlated (P kidney weights were not found significantly correlated (P > 0.01) with the length of renal arteries.

Ectopic pregnancy has remained a significant cause of maternal morbidity and mortality especially in the sub Saharan Africa. A periodic appraisal of its management is paramount. To determine the incidence and associated risk factors, for ectopic pregnancy, review available treatment modalities and suggest interventions to reduce its prevalence, morbidity and mortality. A cross sectional study with retrolective data collection of all cases of ectopic pregnancy managed in Nnamdi Azikiwe University Teaching Hospital, Nnewi, south-east Nigeria between 1(st) January, 2002 and 31(st) December, 2011 was undertaken. Analysis was carried out using Epi-info 2008 version 3.5.1. During the study period, there were a total 98 cases of ectopic pregnancies out of 8,811 deliveries and 1884 gynecological admissions, giving an incidence of 0.9% of all attendants or 1 in 90 deliveries and 5.2% of all gynecological admissions. Only 94.9% (93/98) case files were retrieved and were used in the final analysis. The mean age of the patients was 30.1 (0.7) years while the mean gestational age at presentations was 7.4 weeks. Previous induced abortion, 37.5% (36/93) was the commonest associated risk factor, followed by pelvic infections, 35.5% (33/93). The recurrence rate was 6.5% (6/93). Majority, 80.6% (75/93) presented with abdominal pain and 35.8% (33/93) presented with vaginal bleeding. Up to 88.2% (82/93) had salpingectomy while only 2.5% (2/93) were successfully managed medically with methotrexate therapy following diagnosis with transvaginal ultrasound Missed diagnosis of ectopic pregnancy occurred in 16.1% (15/93). There was no maternal death. Ectopic pregnancy has remained an important gynecological condition in our center. The common identifiable risk factors were induced abortion and pelvic infection. Early first trimester transvaginal ultrasound should be offered to all women for early diagnosis.

Ectopic Varices in the Gastrointestinal Tract: Short- and Long-Term Outcomes of Percutaneous Therapy

Macedo, Thanila A.; Andrews, James C.; Kamath, Patrick S.

2005-01-01

To evaluate the results of percutaneous management of ectopic varices, a retrospective review was carried out of 14 patients (9 men, 5 women; mean age 58 years) who between 1992 and 2001 underwent interventional radiological techniques for management of bleeding ectopic varices. A history of prior abdominal surgery was present in 12 of 14 patients. The interval between the surgery and percutaneous intervention ranged from 2 to 38 years. Transhepatic portal venography confirmed ectopic varices to be the source of portal hypertension-related gastrointestinal bleeding. Embolization of the ectopic varices was performed by a transhepatic approach with coil embolization of the veins draining into the ectopic varices. Transjugular intrahepatic portosystemic shunt (TIPS) was performed in the standard fashion. Eighteen procedures (12 primary coil embolizations, 1 primary TIPS, 2 re-embolizations, 3 secondary TIPS) were performed in 13 patients. One patient was not a candidate for percutaneous treatment. All interventions but one (re-embolization) were technically successful. In 2 of 18 interventions, re-bleeding occurred within 72 hr (both embolization patients). Recurrent bleeding (23 days to 27 months after initial intervention) was identified in 9 procedures (8 coil embolizations, 1 TIPS due to biliary fistula). One patient had TIPS revision because of ultrasound surveillance findings. New encephalopathy developed in 2 of 4 TIPS patients. Percutaneous coil embolization is a simple and safe treatment for bleeding ectopic varices; however, recurrent bleeding is frequent and reintervention often required. TIPS can offer good control of bleeding at the expense of a more complex procedure and associated risk of encephalopathy

Usually, left colon cancer metastasis concerns liver, abdominal lymph nodes and lungs. Other localizations are quite rare occurrences. In spite of this, some uncommon metastasis sites are reported in literature, such as: peritoneum, ovaries, uterus, kidney testis, bones, thyroid, oral cavity and central nervous system. We report two cases of unusual localizations of left colon cancer metastasis localization, one into the retroperitoneal space and the other at the left axillary lynphnodes and between liver and pancreas. In the first reported case the diffusion pathway may have been the lymphatic mesocolic vessels, partially left in place from the previous surgery. In the second case the alleged metastatic lane may have been through the periumbilical lymph nodes to the parasternal lymph nodes and then to the internal mammary ones, finally reaching the axillary limph nodes.

To evaluate safety and efficacy of minipercutaneous nephrolithotomy (Mini-PNL) in management of stones in different types of renal anomalies. Patients with stones ≥2 cm or SWL-resistant stones in anomalous-kidneys treated by Mini-PNL between March 2010 and September 2012 were included prospectively. Mini-PNL was done under regional anesthesia in prone position with fluoroscopic guidance through 18 Fr sheath using semirigid ureteroscope (8.5/11.5 Fr) and pneumatic lithotripter. All patients were followed-up for 2-3 years. Stone-free rate was defined as absence of residual fragments ≥2 mm. Student-T, Mann-Whitney, Chi square (χ 2 ), Fisher-exact, one way ANOVA or Kruskal-Wallis test were used for analysis. Mini-PNL was performed for 59 patients (20 horseshoe, 15 malrotated, 7 polycystic, 13 duplex and 4 ectopic pelvic-kidneys). Mean age was 40.18 ± 12.75 (14-78) years. Mean stone burden was 31.72 ± 21.43 (7.85-141.3) mm 2 . Two tracts were required in 7 (11.9 %) patients. Tubeless Mini-PNL with double-J insertion was performed in all patients except two. Operative time was 50.17 ± 18.73 (15-105) min. Hemoglobin loss was 0.44 ± 0.30 (0-1.4) g/dL. Complications were reported in 15 (25.4 %) patients. No pleural injury, sepsis, perinephric-collection or renal-pelvis perforation were reported. Stone-free rate was 89.8 % (converted to open-surgery in one patient, second-look PNL in two patients, auxiliary SWL in three patients). Stone-free rate improved to 98.3 % after retreatment and auxiliary SWL. Site of puncture was mostly upper calyceal in horseshoe-kidney (80 %), mid calyceal in polycystic-kidney (85.7 %) and lower calyceal in duplex-kidney (46.2 %). Punctures were also significantly infracostal in horseshoe-kidney (100 %) and supracostal in both duplex (53.8 %) and malrotated-kidneys (66.7 %). Mini-PNL is safe for management of stones in anomalous-kidney with SFR comparable to standard-PNL but with less complications.

The purpose of the study was to examine differences in kidney intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) parameters in early-stage diabetic patients versus healthy controls. Nineteen type 2 diabetic patients (group A) with a urinary albumin-to-creatinine ratio (ACR) diabetic kidney changes was determined by receiver operating characteristic analysis. Three radiologists independently measured the parameters derived from IVIM-DWI in the two groups by free-hand placing regions of interest, and the interclass coefficients (ICCs) were analyzed by SPSS.16.0 software. The f values of the kidneys were significantly higher in diabetic patients than in healthy volunteers. The D value of the kidneys was significantly lower in diabetic patients than in healthy volunteers. No significant differences in the D* values of the kidneys were observed between diabetic patients and healthy volunteers. The D values of the right kidneys were significantly higher than those of the left kidneys in both groups. The results of the receiver operating characteristic analysis were as follows: left kidney-f value AUC = 0.650 (cutoff point ≥ 27.49%) and D value AUC = 0.752 (cutoff point ≤ 1.68 × 10 -3  mm 2 /s); and right kidney-f value AUC = 0.650 (cutoff point ≥ 28.24%) and D value AUC = 0.752 (cutoff point ≤ 1.81 × 10 -3 mm 2 /s). The diagnostic performance of the D* value was very low (AUC  0.05). The ICCs of the f value and D value were between 0.637 and 0.827. The ICC of the D* value was less than 0.3. The results of our study suggest that changes in kidneys detected by IVIM-DWI may serve as indicators of early diabetic kidney disease.

The objective of the present study is to describe key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain caused by ectopic pregnancy. For this purpose, two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed in female patients with acute abdominal pain caused by proven ectopic pregnancy in the period between January 2010 and December 2011. The imaging diagnosis of ectopic pregnancy is usually obtained by ultrasonography, however, with the increasing use of computed tomography and magnetic resonance imaging in the assessment of patients with acute abdomen of gynecological origin it is necessary that the radiologist becomes familiar with the main findings observed at these diagnostic methods.

Nagar, Sapna

2012-02-01

Ectopic liver tissue is a rare clinical entity that is mostly asymptomatic and found incidentally. In certain situations, however, patients may present with symptoms of abdominal pain secondary to torsion, compression, obstruction of adjacent organs, or rupture secondary to malignant transformation. Herein, we report a case of a 25-year-old female that presented with acute onset of epigastric pain found to have ectopic liver tissue near the gallbladder complicated by acute hemorrhage necessitating operative intervention in the way of laparoscopic excision and cholecystectomy. The patient\\'s postoperative course was uneventful. Gross pathology demonstrated a 1.2 x 2.8 x 4.5 cm firm purple ovoid structure that histologically revealed extensive hemorrhagic necrosis of benign ectopic liver tissue.

Cushing syndrome is rarely caused by the secretion of cortisol from ovarian tumors. In clinical decision-making, it is important to determine whether the ovarian tumor is capable of secreting cortisol. Selective ovarian and adrenal venous sampling is scarcely reported in the localization of ACTH-independent ectopic Cushing syndrome. We present a case of 40-year-old Chinese woman who had weight gain, hirsutism, hypertension, and menstrual disorder over 6 months. Her physical examination and biochemical assessment revealed adrenocorticotropic hormone-independent Cushing syndrome. Adrenal computed tomography scan indicated no abnormality. A mass of 5.7 cm × 4.2 cm × 3.4 cm was discovered by pelvic ultrasonography. Somatostatin receptor scintigraphy revealed no abnormal radioactivity intake. Combined ovarian and adrenal venous sampling together with a cortisol assay were conducted. Results revealed cortisol concentration of the right-side ovarian vein, left-side ovarian vein, and peripheral vein of 268.60, 29.00, and 35.18 μg/dL, respectively, suggesting a right-side ovarian origin. A right-side salpingo-oophorectomy was performed and the pathological diagnosis revealed ovarian steroid cell tumor, not otherwise specified. The cortisol level was substantially lower after the patient underwent surgery and symptoms of Cushing syndrome disappeared. At 3-year follow-up, the patient remained disease free, and no tumor was observed on pelvic ultrasonogram. Combined ovarian and adrenal venous sampling is valuable in the localization of adrenocorticotropic hormone-independent ectopic Cushing syndrome.

Acromegaly with no pituitary adenoma and no evidence of ectopic source

Directory of Open Access Journals (Sweden)

Full Text Available More than 99% of patients with acromegaly harbor a growth hormone (GH secreting pituitary adenoma. As the time from onset of signs/symptoms to diagnosis of acromegaly is long (symptom onset to diagnosis is often 4-10 years, pituitary adenomas that cause GH excess are often large and are nearly always visible on conventional magnetic resonance imaging (MRI. However, in rare circumstances, acromegalic patients without an ectopic source will not have imaging evidence of a pituitary adenoma. Management of these patients poses special challenge, and once ectopic source of GH/growth-hormone-releasing hormone (GHRH is ruled out, an exploration of pituitary might be useful. We herein report a case of acromegaly with imaging evidence of sellar floor osteoma, but no pituitary adenoma, and negative work up for an ectopic source of GH/GHRH tumor, and on surgical exploration pituitary adenoma could be identified and removed and confirmed on histopathologic examination.

To quantify physical activity and grip strength in pediatric kidney transplant recipients and describe attitudes about exercise and exercise counseling given concerns about allograft injury. This was a cross-sectional analysis of 101 kidney transplant recipients (7-21 years old) >6 months post-transplant. Patients completed the Physical Activity Questionnaire (PAQ). Grip strength was measured with a dynamometer. We asked about activity limitations and provider counseling. Univariate analysis and multiple linear regression were used to determine independent predictors of PAQ score and grip strength z score. We enrolled 101 of 122 eligible patients. Median PAQ score was 2.2 (range 0-5) and was lower compared with controls (P < .001). The average grip strength z score was -1.1 and -0.7 in the right and left hand, respectively. Predictors of lower grip strength were younger age (P = .036), non-African American race (P = .029), lower height z score (P = .010), and longer percentage of lifetime with kidney disease (P = .029). Although 49% and 67% limited exercise before and after transplant, respectively, 67% reported increased activity after transplant. By parent report, provider counseling included limiting certain activities (71%) and encouraging regular exercise (45%). Physical activity and grip strength are low after kidney transplant. Patients perceive an emphasis on exercise limitations rather than the benefits of regular exercise. Interventions that encourage physical activity may be beneficial. Copyright © 2016 Elsevier Inc.

A retrospective cohort study on the incidence of ectopic pregnancy in fresh and frozen-thawed embryo transfer cycles from January 1 st , 2010, to January 1 st , 2015. Infertile women undergoing frozen-thawed transfer cycles or fresh transfer cycles. In-vitro fertilization, fresh embryo transfer, frozen-thawed embryo transfer, ectopic pregnancy. Ectopic pregnancy rate and clinical pregnancy rate. A total of 69 756 in vitro fertilization-embryo transfer cycles from 2010 to 2015 were analyzed, including 45 960 (65.9%) fresh and 23 796 (34.1%) frozen-thawed embryo transfer cycles. The clinical pregnancy rate per embryo transfer was slightly lower in fresh embryo transfer cycles compared with frozen-thawed embryo transfer cycles (40.8% vs 43.1%, P cycles, blastocyst transfer shows a significantly lower incidence of ectopic pregnancy (0.8% vs 1.8%, P = .002) in comparison with day 3 cleavage embryo transfer. The risk of ectopic pregnancy is lower in frozen-thawed embryo transfer cycles than fresh embryo transfer cycles, and blastocyst transfer could further decrease the ectopic pregnancy rate in frozen-thawed embryo transfer cycles.

A kidney from hell? A nephrological view of the Whitechapel murders in 1888.

In the poor Whitechapel district of the East End of London in the fall of 1888, at least five prostitutes were brutally murdered, and in all but one case, also mutilated. The murderer was never caught and became known by his nickname 'Jack the Ripper'. The left kidney and the uterus were cut out and taken away from one of the victims named Catherine Eddowes. A kidney was also cut out of the body from another victim, but not taken away. Two weeks later, George Lusk, president of the Whitechapel Vigilance Committee, received a small cardboard box with half of a longitudinally divided kidney and a letter entitled 'From hell' claiming that the kidney inside the box was taken from the victim. The kidney was brought to Dr Thomas Horrocks Openshaw, the Curator of the London Pathological Museum, where the kidney could be microscopically examined. The press jumped on the topic and made a circumstantial case that this kidney had been indeed torn from the body of Catherine Eddowes. According to the later memoirs of Major Henry Smith of the City Police published more than 20 years after the incident, the kidney left in the corpse of Catherine Eddowes was in an advanced stage of Bright's disease and the kidney sent to George Lusk was in exactly a similar stage. Today, the majority of criminologists believe that the kidney sent to Mr Lusk was a hoax as were other letters signed with Jack the Ripper. However, the murderer took organs from his victims, and in the case of Catherine Eddowes, the kidney. Serial killers often mutilate their victims and abscond with the removed body parts as trophies. By removing the kidney from Catherine Eddowes, Jack the Ripper may have tried to take possession of the conscience, emotions and desires of one of his victims, attributes residing in the kidney as described in the Bible. Jack the Ripper was never caught; many suspects have been suggested, and the murder series ended as suddenly as it had begun. We will never know who this mentally

Ectopic thyroid tissue remains a rare developmental abnormality involving defective or aberrant embryogenesis of the thyroid gland during its passage from the floor of the primitive foregut to its usual final position in pre-tracheal region of the neck. Its specific prevalence accounts about 1 case per 100.000-300.000 persons and one in 4.000-8.000 patients with thyroid disease show this condition. The cause of this defect is not fully known. Despite genetic factors have been associated with thyroid gland morphogenesis and differentiation, just recently some mutation has been associated with human thyroid ectopy. Lingual region in the most common site of thyroid ectopy but ectopic thyroid tissue were found in other head and neck locations. Nevertheless, aberrant ectopic thyroid tissue has been found in other places distant from the neck region. Ectopic tissue is affected by different pathological changes that occur in the normal eutopic thyroid. Patients may present insidiously or as an emergency. Diagnostic management of thyroid ectopy is performed by radionuclide thyroid imaging, ultrasonography, CT scan, MRI, biopsy and thyroid function tests. Asymptomatic euthyroid patients with ectopic thyroid do not usually require therapy but are kept under observation. For those with symptoms, treatment depends on size of the gland, nature of symptoms, thyroid function status and histological findings. Surgical excision is often required as treatment for this condition. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Implantation of Right Kidneys: Is the Risk of Technical Graft Loss Real?

Khan, Taqi T; Ahmad, Nadeem; Siddique, Kashif; Fourtounas, Konstantinos

2018-05-01

The left kidney (LK) is preferred by transplant surgeons, because its vein is always of good length and has a thick wall that enables safe suturing. On the other hand, the right renal vein is generally shorter and thinner walled, and well known for its technical difficulty during venous anastomosis, and can result in graft loss. We examined our living (LD) and deceased donor (DD) recipient data and compared the incidence of technical graft loss and early graft function in right and left kidneys. A cohort of 58 adult and pediatric recipients received an LD or DD kidney between January 2015 and December 2016. The donor and recipient data were retrieved and retrospectively analyzed. Technical graft loss was defined as graft thrombosis within the 7 days after transplant. Right kidneys (RKs) were not a risk factor for technical graft loss, and no graft was lost for technical reasons in either LD or DD transplants. Early graft function in LK and RKs was also comparable in the LD cohort, and there were no LKs in the DD cohort. Based on our data, the use of RKs was not a risk factor for technical graft loss and early graft function was comparable to LKs.

Objective The aim of this study was to investigate the correlation between non-dipper circadian rhythm of blood pressure (BP) and left ventricular hypertrophy (LVH) in patients with chronic kidney disease (CKD). Methods and results All 257 patients with stage 1 to 5 CKD were enrolled in the study and classified into a CKD1-3 group and a CKD4-5 group according to renal function. The parameters and circadian rhythm of BP were measured by a GE Marquette Tonoport V Eng dynamic sphygmomanometer, and cardiac structure was examined by echocardiography. The incidence of abnormal circadian BP rhythm (non-dipper rhythm) was quite high (75.4% in all enrolled patients and 71.3% in the patients with normal BP levels) in CKD patients and increased with the deterioration of renal function. Changes of cardiac structure such as LVH in patients with non-dipper BP were more distinct than in patients with dipper BP. The development of left ventricular mass index (LVMI) correlated positively with the incidence of non-dipper BP rhythm. Multiple regression analysis showed that 24-h systolic BP (β = 0.417, P circadian rhythm of blood pressure was quite high in CKD patients and increased with the deterioration of renal function. Non-dipper circadian rhythm of BP is closely related with LVMI.

Full Text Available PurposeCardiac screening in adult kidney transplant candidates with myocardial perfusion scintigraphy (MPS can reveal findings associated with increased risk for coronary heart disease events, but the exact value of this screening test is still undetermined.MethodsNarrative review based on the available literature and guidelines on the yield, benefits, and harms of MPS screening in kidney transplant candidates.ResultsAlthough coronary angiography carries low risk in general population, it is not without risk particularly in patients with complex comorbid disease and the use of intravenous contrast media may precipitate a need for hospitalization and death. We could avoid invasive coronary angiography in patients with chronic kidney disease, although with high coronary calcium score, but good left ventricle function and normal perfusion, evaluated by Gated single-photon emission computed tomographic (SPECT MPS. In fact, although Gated SPECT MPS has not a high sensitivity, it provides some variables that are closely related to sudden death: post-stress and rest-ejection fraction and left ventricular volumes, left ventricle muscle mass, extent of ischemia and scar.ConclusionsGated SPECT MPS is a valid noninvasive cardiac screening test. It can be used as alternative to stress echocardiography in kidney transplant candidates with high cardiovascular risk and a positive or inconclusive exercise tolerance ECG test.Patients with abnormal perfusion and cardiac dysfunction should undergo invasive coronary artery imaging and endovascular treatment, while angiography could be avoided in patients with normal MPI, having good long-term prognosis.

Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results. We have encountered eight cases of gastrointestinal ectopic variceal bleeding in five patients in the last five years. All patients were diagnosed with liver cirrhosis presenting melena or hematemesis. All patients were treated with various endoscopic modalities (endoscopic variceal obturation [EVO] with cyanoacrylate in five cases, endoscopic variceal band ligation (EVL) in two cases, hemoclipping in one case). Satisfactory hemostasis was achieved without radiologic interventions in all cases. EVO and EVL each caused one case of portal biliopathy, and EVL induced ulcer bleeding in one case. EVO generally accomplished better results of variceal obturations than EVL or hemoclipping, without serious adverse events. EVO may be an effective modality for control of ectopic variceal bleeding without radiologic intervention or surgery.

Finite element modeling of the human kidney for probabilistic occupant models: Statistical shape analysis and mesh morphing.

Yates, Keegan M; Untaroiu, Costin D

2018-04-16

Statistical shape analysis was conducted on 15 pairs (left and right) of human kidneys. It was shown that the left and right kidney were significantly different in size and shape. In addition, several common modes of kidney variation were identified using statistical shape analysis. Semi-automatic mesh morphing techniques have been developed to efficiently create subject specific meshes from a template mesh with a similar geometry. Subject specific meshes as well as probabilistic kidney meshes were created from a template mesh. Mesh quality remained about the same as the template mesh while only taking a fraction of the time to create the mesh from scratch or morph with manually identified landmarks. This technique can help enhance the quality of information gathered from experimental testing with subject specific meshes as well as help to more efficiently predict injury by creating models with the mean shape as well as models at the extremes for each principal component.

Ectopic lymphocytic thyroiditis: A case report and treatment options

Directory of Open Access Journals (Sweden)

Irami Araujo-Filho

2017-12-01

Full Text Available The presence of ectopic thyroid tissue is a rare entity. Non-gland migration occurs during the early stages of embryogenesis to the normal cervical location. Thus, ectopic tissue is lodged, in general, in the path of the thyroglossal duct in the middle line of the neck. The most common location is in the lingual zone, being the lingual thyroid. This, in most cases, will be asymptomatic. However, it is able to manifest itself with symptoms of dysphagia, dysphonia, obstruction of the upper airways or hemorrhage at any moment between childhood and adulthood. This article is a review of this disease, targeting mainly conduct, still very controversial in the literature. [Arch Clin Exp Surg 2017; 6(4.000: 221-227

Case Report of Ectopic Liver on Gallbladder Serosa with a Brief Review of the Literature

Vishnu R. Mani

2016-01-01

Full Text Available This case describes an intraoperative incidental finding and surgical removal of ectopic liver tissue attached to the gallbladder during a standard laparoscopic cholecystectomy for acute cholecystitis. These anomalies are rare, with interesting associations and possible clinically relevant complications. The details of the case, along with a brief literature review of embryology, common ectopic sites, and associations/complications, are presented in this paper. Since laparoscopic cholecystectomy is a very common procedure, it is important to increase vigilance of ectopic liver tissues during surgeries to minimize complications and provide optimal management.

Severe Cushing's syndrome and bilateral pulmonary nodules: beyond ectopic ACTH.

Tavares Bello, Carlos; van der Poest Clement, Emma; Feelders, Richard

2017-01-01

Cushing's syndrome is a rare disease that results from prolonged exposure to supraphysiological levels of glucocorticoids. Severe and rapidly progressive cases are often, but not exclusively, attributable to ectopic ACTH secretion. Extreme hypercortisolism usually has florid metabolic consequences and is associated with an increased infectious and thrombotic risk. The authors report on a case of a 51-year-old male that presented with severe Cushing's syndrome secondary to an ACTH-secreting pituitary macroadenoma, whose diagnostic workup was affected by concurrent subclinical multifocal pulmonary infectious nodules. The case is noteworthy for the atypically severe presentation of Cushing's disease, and it should remind the clinician of the possible infectious and thrombotic complications associated with Cushing's syndrome. Severe Cushing's syndrome is not always caused by ectopic ACTH secretion.Hypercortisolism is a state of immunosuppression, being associated with an increased risk for opportunistic infections.Infectious pulmonary infiltrates may lead to imaging diagnostic dilemmas when investigating a suspected ectopic ACTH secretion.Cushing's syndrome carries an increased thromboembolic risk that may even persist after successful surgical management.Antibiotic and venous thromboembolism prophylaxis should be considered in every patient with severe Cushing's syndrome.

Ectopic breast tissue is defined as glands located outside of the breast. It can be found anywhere along the milk line extending from the axilla to the groin, and can occur in the vulva. Ectopic breast tissue should be excised because it may develop benign or malignant pathologic processes. Less than 40 cases of fibroadenoma in the vulva have been reported in the literature. We report a case of a 37-year-old woman presenting a solitary vulvar mass. The mass was excised completely, and histology demonstrated an ectopic breast fibroadenoma. This is one of the few reports on the benign pathologies of vulvar mammary glands.

Given the critical role of tumor O2 delivery in patient prognosis and the rise in preclinical exercise oncology studies, we investigated tumor and host tissue blood flow at rest and during exercise as well as vascular reactivity using a rat prostate cancer model grown in two transplantation sites. In male COP/CrCrl rats, blood flow (via radiolabeled microspheres) to prostate tumors [R3327-MatLyLu cells injected in the left flank (ectopic) or ventral prostate (orthotopic)] and host tissue was measured at rest and during a bout of mild-intensity exercise. α-Adrenergic vasoconstriction to norepinephrine (NE: 10(-9) to 10(-4) M) was determined in arterioles perforating the tumors and host tissue. To determine host tissue exercise hyperemia in healthy tissue, a sham-operated group was included. Blood flow was lower at rest and during exercise in ectopic tumors and host tissue (subcutaneous adipose) vs. the orthotopic tumor and host tissue (prostate). During exercise, blood flow to the ectopic tumor significantly decreased by 25 ± 5% (SE), whereas flow to the orthotopic tumor increased by 181 ± 30%. Maximal vasoconstriction to NE was not different between arterioles from either tumor location. However, there was a significantly higher peak vasoconstriction to NE in subcutaneous adipose arterioles (92 ± 7%) vs. prostate arterioles (55 ± 7%). Establishment of the tumor did not alter host tissue blood flow from either location at rest or during exercise. These data demonstrate that blood flow in tumors is dependent on host tissue hemodynamics and that the location of the tumor may critically affect how exercise impacts the tumor microenvironment and treatment outcomes.

Full Text Available Rhabdomyosarcoma is the commonest soft tissue sarcoma in both children and adolescents representing 40% of such tumours in North America and more than 50% in Africa. The involvement of the paratesticular tissue, testis and the kidney are generally rare and more so when it is occurring synchronously. We present a case of 22 year old male with inguinoscrotal swelling, fever and abdominal distention who was diagnosed as having obstructed left inguinoscrotal hernia and a right renal mass. The patient had surgery, and a diagnosis of synchronous rhabdomyosarcoma of the left testis, paratesticular tissue and right kidney was made by histology and immunohistochemistry.

Endovascular treatment of external iliac vein stenosis caused by graft compression after kidney transplantation

Directory of Open Access Journals (Sweden)

Willamax Oliveira de Sousa

2013-06-01

Full Text Available A 57-year old patient presented with approximately 80% stenosis of the left external iliac vein due to compression by the renal graft after kidney transplantation. The initial clinical manifestation of this vascular complication was progressive edema of the left lower limb, starting in the foot during the immediate postoperative period and reaching the thigh. Renal function also deteriorated during the first four months after transplantation. Venous Doppler ultrasound findings were suggestive of a diagnosis of extrinsic compression by the kidney graft and so phlebography was ordered, confirming stenosis of the left external iliac vein. The patient was initially treated with balloon angioplasty, but there was still residual stenosis so a stent was inserted, eliminating the stenosis. The edema reduced over time and the patient's renal function improved. While vascular complications are rare, and potentially severe, events, success rates are good if treatment is started early.

Dioctophyma renale is frequently observed in dogs from rural areas. From a total of 67 necropsies carried out from May to December of 2004, 56 were dogs, which came from the minicipality of Cachoeiro do Itapemirim, two animals parasited for D. renale. In one of these animals in a mass of epiplon a nematode female of 15 cm of length was found in ectopic position. The right kidney was atrophic and with the presence of 2 females (58 and 50 cm) and 2 males (21 cm each). In the second animal, the kidneys were morphologically different. The left kidney was presented hypertrophic, while right kidney was observed a female with 45 cm. The recovered helminths were identified and fixed in AFA. During the ovariectomy of a dog of the same region a male nematode of approximately 20 cm was found in site the abdominal cavity. All of them were identified as D. renale.

2015-01-01

Full Text Available An ectopic tonsil is defined as tonsillar tissue that develops in areas outside of the four major tonsil groups: the palatine, lingual, pharyngeal, and tubal tonsils. The occurrence of tonsillar tissue in the oral cavity in ectopic locations, its prevalence, and its developmental mechanisms that belong to its formation remain unclear. In this report, we describe a rare case of bilateral symmetric ectopic oral tonsillar tissue located at the ventral surface of the tongue along with two solitary cases arising from the floor of the mouth. The role of immune system and its aberrant response leading to ectopic deposits desires further studies. As an ectopic tonsil may simulate a benign soft tissue tumor, this case series highlights the importance of this entity in our clinical differential diagnosis of oral soft tissue masses.

Objective: To evaluate the value of multislice CT angiography (MSCTA) in vascular complications of transplant kidney. Methods: Six transplant kidneys were undergone enhanced MSCT scanning postoperation. MPR, CPR, VR and VP reformation were performed to observe transplant kidney's parenchyma, renal artery, and renal vein. To analysis all the reconstruction technique and find the advantage and shortage of them. Results: One case showed enhanced function of transplant kidney decreased. Vascular stenosis was found in one case and false aneurysm was found in another transplant kidney. Transplant kidney were enhanced normal in the left three cases. MPR couldn't reconstruct all the tortuous vessel of renal hilus in one plane. But all six cases could expose the vessel of renal hilus very clearly in coronal section and sagittal plane of CPR. Six cases of VR could observe the vessel direction and lesions outside vessel through rotate the reconstruction image. VP could see through inside the vessel of transplant kidney. Conclusion: MSCTA has an important role as an imaging technique to evaluate vascular complications of transplant kidney, it can replace DSA. (authors)

Diabetes mellitus and hypertension are major risk factors for chronic kidney injury, together accounting for >70% of end-stage renal disease. In this study, we assessed interactions of hypertension and diabetes mellitus in causing kidney dysfunction and injury and the role of endoplasmic reticulum (ER) stress. Hypertension was induced by aorta constriction (AC) between the renal arteries in 6-month-old male Goto-Kakizaki (GK) type 2 diabetic and control Wistar rats. Fasting plasma glucose averaged 162±11 and 87±2 mg/dL in GK and Wistar rats, respectively. AC produced hypertension in the right kidney (above AC) and near normal blood pressure in the left kidney (below AC), with both kidneys exposed to the same levels of glucose, circulating hormones, and neural influences. After 8 weeks of AC, blood pressure above the AC (and in the right kidney) increased from 109±1 to 152±5 mm Hg in GK rats and from 106±4 to 141±5 mm Hg in Wistar rats. The diabetic-hypertensive right kidneys in GK-AC rats had much greater increases in albumin excretion and histological injury compared with left kidneys (diabetes mellitus only) of GK rats or right kidneys (hypertension only) of Wistar-AC rats. Marked increases in ER stress and oxidative stress indicators were observed in diabetic-hypertensive kidneys of GK-AC rats. Inhibition of ER stress with tauroursodeoxycholic acid for 6 weeks reduced blood pressure (135±4 versus 151±4 mm Hg), albumin excretion, ER and oxidative stress, and glomerular injury, while increasing glomerular filtration rate in hypertensive-diabetic kidneys. These results suggest that diabetes mellitus and hypertension interact synergistically to promote kidney dysfunction and injury via ER stress. © 2017 American Heart Association, Inc.

A case report of a rare presentation of follicular thyroid carcinoma with pelvic and kidney metastases: Emphasis on multidisciplinary and multimodality management approach

Full Text Available Introduction: Follicular thyroid carcinoma (FTC is the second most common type of thyroid cancer, after papillary thyroid carcinoma (PTC, accounting for approximately 10% of all malignant thyroid tumours with higher predilection for women. FTC demonstrates capsular and/or vascular invasion and often presents with distant metastasis in 20%–30% of cases via the haematogenous spread. FTC tends to commonly metastasize to the lung and bone although other sites have been identified. Kidney metastasis from a primary FTC however is rare and has not been widely reported. We report a case of FTC with metastatic to the kidney in a patient presenting with a large left pelvic mass. Case presentation: A 54-year-old, Malay, lady with underlying hypertension and dyslipidaemia presented with chronic left pelvic pain since 1 year ago, following a fall during a recent vacation trip. She also experienced significant unintentional weight loss for the past few months. Clinical examination noted an ill-defined palpable firm mass over the left inner thigh. Pelvic radiograph showed a solitary ill-defined osteolytic lesion at the left superior and inferior pubic rami with cortical destruction. MRI of the pelvis showed a large lobulated enhancing expansile mass originating from the left pubic bone measuring 10.0(AP × 6.0(W × 8.5(CC cm, hypointense signal on T1W and hyperintense signal on T2W. The mass infiltrated adjacent bony structures and muscles. Patient subsequently undergone core biopsy of the left pelvic mass and histopathological examination (HPE noted metastatic follicular thyroid carcinoma. An ultrasound examination of the thyroid showed a multinodular goitre with suspicious nodule in the left thyroid gland. Pre-operative contrast-enhanced computed tomography (CECT showed primary thyroid carcinoma with nodal, lung and bone metastases with possible left kidney involvement. Total thyroidectomy was ensued and follicular thyroid carcinoma was confirmed based on

To share the diagnostic and management challenges created by an extremely rare airway lesion-the subglottic ectopic thymic cyst. Case report and literature review. We review the presentation, management, and clinical course of an infant who presented with a subglottic mass that was histologically confirmed as a thymic cyst. A brief literature review supplements the case presentation Results: We present the third described case of an ectopic thymic cyst presenting as a subglottic mass. The differential diagnosis of subglottic masses in neonates consists primarily of subglottic hemangioma and mucous retention cysts. Otolaryngologists must be prepared for unexpected findings when dealing with critical airways. We compare the presentation and management of our patient with the 2 previously described cases. We propose an embryologic theory for the origin of these rare lesions. An ectopic thymic cyst is a rare and unexpected cause of neonatal stridor. Management of pediatric airway lesions must allow for unexpected findings at the time of diagnostic and therapeutic endoscopy. The appropriate management of subglottic thymic cysts is poorly defined, but close surveillance for recurrence is mandatory.

An olive-shaped probe (25 X 12 mm) with 41 evenly distributed recording electrodes on its surface was introduced into the left ventricles of seven open-chest dogs via the left atrium. In two other dogs a cylindrical probe (40 X 3 mm) was used. Electrical stimuli were delivered at 66 endocardial, midwall, or epicardial sites in the left and right ventricular walls and the septum. Mechanical stimuli were also applied at various epicardial sites. On-line mapping of equipotential contour lines on the surface of the probe invariably revealed a clear-cut potential minimum on the electrode that faced the pacing site. Time of appearance of potential minimum was 3 to 5 msec after endocardial stimuli, 10 to 25 msec for midwall and epicardial pacing, and 30 msec or more for right ventricular stimulation. Simultaneous stimulation at two sites 1.2 cm apart gave rise to two separate minima on the maps. "Pseudoisochrones" derived from electrograms recorded by the new probe were slightly less accurate in indicating the site of origin of extrasystoles. We conclude that equipotential and "isochrone" contour maps recorded from an array of semidirect electrodes, regularly distributed on the surface of an intraventricular probe, provide information on the site of origin (location and intramural depth) of ectopic paced beats in a normal dog heart.

Full Text Available Abstract Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric implant, and a coexisting infiltrating urothelial carcinoma of the ureter in a 64-year-old man. Histopathological examination and immunohistochemical studuies showed the classic features of mesenchymal chondrosarcoma in kidney, as well as a few infiltrating urothelial in ureter. Multitarget fluorescence in situ hybridization (FISH suggested that the development of the urothelial carcinoma in the ureter may be triggered or induced by the chondrosarcoma component. The patient died 2 month after left nephro-ureterectomy. This is the first reported case of a primary mesenchymal chondrosarcoma of the kidney with coexisting infiltrating urothelial carcinoma of the ureter.

Full Text Available We present a case of tacrolimus-induced encephalopathy after successful kidney transplantation. An 11-year-old girl presented with sudden onset of neurologic symptoms, hypertension, and psychiatric symptoms, with normal kidney function, after kidney transplantation. The symptoms improved after cessation of tacrolimus. Magnetic resonance imaging (MRI showed acute infarction of the middle cerebral artery (MCA territory in the right frontal lobe. Three days later, she had normal mental function and maintained normal blood pressure with left hemiparesis. Follow-up MRI was performed on D19, showing new infarct lesions at both cerebral hemispheres. Ten days later, MRI showed further improvement, but brain single photon emission computed tomography (SPECT showed mild reduction of uptake in both the anterior cingulate gyrus and the left thalamus. One month after onset of symptoms, angiography showed complete resolution of stenosis. However, presenting as a mild fine motor disability of both hands and mild dysarthria, what had been atrophy at both centrum semiovale at 4 months now showed progression to encephalomalacia. There are two points of interest in this case. First, encephalopathy occurred after administration of tacrolimus and improved after discontinuation of the drug. Second, the development of right-side hemiplegia could not be explained by conventional MRI; but through diffusion tensor imaging (DTI and diffusion tensor tractography (DTT of white matter tract, visualization was possible.

Schistosomiasis is the second endemic parasitic disease in the world and is a common cause of urogenital infections. Ectopic pregnancies due to tubal obstruction by schistosoma's eggs are usually reported in Africa. Schistosomiasis also affects travelers but infection of the female genital tract is less frequently described. We report an unusual clinical case of two successive ectopic pregnancies with tubal schistosomiasis in a French woman, seven years after a travel to Mali. The first event was discovered after histologic examination of salpingectomy and the second event required a controlateral salpingotomy with an injection of methotrexate, two months later.

This study reports the first case of ectopic parathyroid adenoma, diagnosed in the Department of Nuclear Medicine in Antananarivo. This clinical vignette illustrates the interest of the MIBI-Tc-99 m scan in locating this adenoma and its diagnostic confirmation after six years of erratic diagnosis. A whole body bone scintigraphy has also allowed to assess the state of bone metabolism and study outbreaks of fracture. The parathyroid scintigraphy was carried out after intra-venous administration of 666 MBq of MIBI- 99m Tc. Dynamic images, static early and late static were acquired with a gamma camera E-Cam Siemens. The whole body bone scan was carried out after administration of 555 MBq of M.D.P.-Tc-99 m. The results evidenced the presence of an para-aortic increased uptake area pointing to a left parathyroid adenoma. The persistence of a late left sub maxillary increased uptake area raises, however, a reservation about the existence of a second adenoma. The bone scan displayed global skeletal remodeling, non suggestive of metastases, as it was mentioned with the CT-scan. In a diagnostic tools limited environment, skeletal pain refractory to pain-killers, a chronic hypercalcemia associated with an increased parathyroid hormone level, should trigger the scintigraphic exploration in order to avoid bone and renal complications

Human leukocyte antigen G (HLA-G) is a regulatory molecule that is expressed in the cytotrophoblast during implantation and is thought to allow the tolerance and the development of the semiallogeneic embryo. In vitro, HLA-G inhibits natural killer (NK) cell and CD8 T-cell cytotoxicity. HLA-G also decreases CD4 T-cell expansion. This suggests that it participates in the acceptance of allogeneic organ transplants in humans. We here describe the detection of high concentration of HLA-G in serum from liver-kidney transplant patients, but not in kidney transplant patients. This finding is supported by the ectopic expression of HLA-G in graft biopsies. Finally, its association with a low number of acute transplant rejections, especially in liver-kidney transplant patients led us to propose that HLA-G may serve to monitor transplant patients who are likely to accept their allograft and, thus, may benefit of a reduced immunosuppressive treatment.

Cushing's syndrome (CS) is a rare but severe clinical condition represented by an excessive endogenous cortisol secretion and hence excess circulating free cortisol, characterized by loss of the normal feedback regulation and circadian rhythm of the hypothalamic-pituitary axis due to inappropriate secretion of ACTH from a pituitary tumor (Cushing's disease, CD) or an ectopic source (ectopic ACTH secretion, EAS). The remaining causes (20%) are ACTH independent. As soon as the diagnosis is established, the therapeutic goal is the removal of the tumor. Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate) or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”). Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands) and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors) which have a significant activity against aggressive pituitary or ectopic tumors.

Obesity and overweight are strongly associated with cardiovascular morbidity and mortality. However, there are limited data on the association between excess weight and the risk of ectopic ventricular activity. We investigated the association between body mass index (BMI) and the risk for ectopic ventricular activity (defined as multiple ventricular premature beats (≥3), ventricular bigeminy, nonsustained ventricular tachycardia or sustained ventricular tachycardia) during exercise stress testing among 22,516 apparently healthy men and women who attended periodic health screening examinations between the years 2000 and 2014. All subjects had completed maximal exercise stress testing annually according to the Bruce protocol. Subjects were divided at baseline into three groups: normal weight (BMI ≥ 18.5 kg/m(2) andexercise-induced ectopic ventricular activity arrhythmias was highest among obese subjects, intermediate among overweight subjects and lowest among subjects with normal weight (3.4%, 2.7% and 2.2% respectively; p exercise compared with subjects with normal weight (p = 0.005), and that each 1 kg/m(2) increase in BMI was associated with a significant 4% (p = 0.002) increased adjusted risk for exercise-induced ventricular arrhythmias. Obesity is independently associated with increased likelihood of ectopic ventricular arrhythmia during exercise. © The European Society of Cardiology 2015.

Ischemic reperfusion injuries (IRIs) are caused by return of blood to a tissue or organ after a period without oxygen or nutrients. Damage in the microvasculature causes an inflammatory response and heterogeneous scarring, which is associated with an increase in collagen in the extracellular matrix. Although most often associated with heart attacks and strokes, IRI also occurs when blood reperfuses a transplanted organ. Currently, monitoring for IRI is limited to biopsies, which are invasive and sample a limited area. In this work, we explored photoacoustic (PA) biomarkers of scarring. IRI events were induced in mice (n=2) by clamping the left renal artery, then re-establishing flow. At 53 days post-surgery, kidneys were saline perfused and cut in half laterally. One half was immediately imaged with a VevoX system (Fujifilm-VisualSonics, Toronto) in two near infrared ranges - 680 to 970 nm (NIR), and 1200 to 1350 nm (NIR II). The other half was decellularized and then imaged at NIR and NIR II. Regions of interest were manually identified and analyzed for each kidney. For both cellularized and decellularized samples, the PA signal ratio based on irradiation wavelengths of 715:930 nm was higher in damaged kidneys than for undamaged kidneys (p collagen in the NIR II range, while healthy kidneys did not. Collagen rich spectra were more apparent in decellularized kidneys, suggesting that in the cellularized samples, other components may be contributing to the signal. PA imaging using spectral ratios associated with collagen signatures may provide a non-invasive tool to determine areas of tissue damage due to IRIs.

International Nuclear Information System (INIS)

Pan Feng; Xiong Bin

2011-01-01

Objective: To assess the clinical value of bilateral uterine artery chemotherapy embolization (UACE) for cervical ectopic pregnancy analyzed. Methods: Clinical records of 40 patients with cervical ectopic pregnancy treated using UACE were retrospectively analyzed. Results: 8 patients with severe active vaginal bleeding after curettage were treated urgently with UACE. The remaining 32 patients were treated with UACE combined with sequential ultrasound-guided curettage. Active vaginal bleeding was stopped after UACE. There was no recurrent hemorrhage with the sequential ultrasound-guided curettage procedure. The β-HCG levels of all patients were normalized after 1 month. Conclusion: Bilateral uterine artery chemotherapy embolization is valuable as emergency treatment for patients with severe vaginal bleeding from cervical ectopic pregnancy. UACE combined with sequential ultrasound-guided curettage may be more effective. (authors)

An account is given of a series of ectopic ureterocele present in 14 male infants. The malformation is found to be more complex than in the female. The ipsilateral renal function is severely impaired or abolished and obstruction to the bladder outflow common. Associated dilatation and elongation of the posterior urethra during micturition may result in a valvelike appearance. Eversion of the male ureterocele is common and possible mechanisms to account for this event are discussed. (Auth.)

When treating pancreatic cancer using standard (ST) 3D conformal radiotherapy (3D-CRT) beam arrangements, the kidneys often receive a higher dose than their probable tolerance limit. Our aim was to elaborate a new planning method that-similarly to IMRT-effectively spares the kidneys without compromising the target coverage. Conformal kidneys sparing (CONKISS) 5-field, noncoplanar plans were compared with ST plans for 23 consecutive patients retrospectively. Optimal beam arrangements were used consisting of a left- and right-wedged beam-pair and an anteroposterior beam inclined in the caudal direction. The wedge direction determination (WEDDE) algorithm was developed to adjust the adequate direction of wedges. The aimed organs at risk (OARs) mean dose limits were: kidney <12 Gy, liver <25 Gy, small bowels <30 Gy, and spinal cord maximum <45 Gy. Conformity and homogeneity indexes with z-test were used to evaluate and compare the different planning approaches. The mean dose to the kidneys decreased significantly (p < 0.05): left kidney 7.7 vs. 10.7 Gy, right kidney 9.1 vs. 11.7 Gy. Meanwhile the mean dose to the liver increased significantly (18.1 vs. 15.0 Gy). The changes in the conformity, homogeneity, and in the doses to other OARs were not significant. The CONKISS method balances the load among the OARs and significantly reduces the dose to the kidneys, without any significant change in the conformity and homogeneity. Using 3D-CRT the CONKISS method can be a smart alternative to IMRT to enhance the possibility of dose escalation.

Symptomatology in thirty patients with hydatid cyst of kidney treated in the Urologic Clinic, UHC, Avicenne, Rabat, was florid (83% with pain and 43% with a mass in the flank) and sometimes specific (27% of cases). Associated hypertension was an exceptional finding. Preoperative diagnostic investigations included ultrasound and CT scan imaging, replacing arteriography to a great extent. Approach to surgical treatment was usually by a lombotomy (64%) or even a Baraya incision (23%), followed by treatment of the renal cyst itself (a case of silent kidney on IVU treated by resection of a protruding dome). Nephrectomy was frequently necessary (47%) for renal lesions. When conservative therapy appeared sufficient the only procedure adopted, apart from specific cases, was resection of a protruding dome even when the hydatid cyst was discharging into excretory pathways. Splenectomy was sometimes necessary (2 of 22 cases) for hydatid cyst of left kidney. This series emphasizes the safety of surgery for hydatid cyst of kidney since the only death reported occurred 2 months after operation in a patient with an associated renal sarcoma.

Full Text Available Congenital giant megaureter presents as abdominal mass and impose diagnostic difficulties. It can be associated with other upper urinary tract anomalies. A female newborn with antenatal diagnosis of polycystic kidneys was admitted at birth due to lower abdominal mass. Ultrasound and CT scans diagnosed a multiloculated cystic lesion in the mid and lower abdomen along with right side multicystic kidney. At laparotomy, an extaperitoneal, lobulated cystic swelling was found due to rightside giant megaureter. Its lower end was of normal caliber and orthotopic. End cutaneous ureterostomy was done. Intravenous urogram and isotope renograms showed nonfunctioning right kidney. She also had grade II vesicoureteral reflux on left side. Child suffered urinary infection twice. At 9m age, right nephroureterectomy was done. Histopathologic examination was consistent with cystic renal dysplasia and dilated ureter. This is the first case report of giant megaureter associated with ipsilateral multicystic dysplastic kidney in newborn.

Nephroureterectomy for transplantation has increased owing to the greater number of deceased donors. Anatomic variations may complicate the procedure or, if unrecognized, compromise the viability of kidneys for transplantation. We reviewed 254 surgical descriptions of nephroureterectomy specimens from January 2008 to December 2009. All organs collected according by standard techniques were evaluated for age, cause of death, renal function, frequency of injury during the procedure, as well as variations in the vascular and collecting systems. The mean donor age was 42 years (range, 2-74). The mean serum creatinine was 1.2 mg/dL (range, 1.0-7.0). The causes of death were cerebrovascular cause (stroke; n = 130), traumatic brain injury (n = 81) or other cause (n = 43). Among the anatomic variations: 8.6% (n = 22) were right arterial anatomical variations: 19 cases with 2 arteries and 3 cases with 3 arteries. In 25 cases (9.8%) the identified variation was the left artery: 2 arteries (n = 23), 3 arteries (n = 1) and 4 arteries (n = 1). We observed 9.8% on right side and 1.5% on left side venous anatomic variations, including 24 cases with 2 veins on the right side and 4 cases with 2 veins on the left side. Three cases of a retroaortic left renal vein and 1 case of a retro necklace vein (anterior and posterior to the aorta). Two cases of ureteral duplication were noted on the left and 1 on the right kidney. There were 3 horseshoe and 1 pelvic kidney. In 7.5% of cases, an injury to the graft included ureteral (n = 3), arterial (n = 10), or venous (n = 6). The most common anatomic variation was arterial (17.8%). Duplication of the renal vein was more frequent on the right. The high incidences of anatomic variations require more attention in the dissection of the renal hilum to avoid an injury that may compromise the graft. Copyright © 2011 Elsevier Inc.

In view of the prevalence of ectopic bone development after hip surgery, a review has been done on the reports appearing in the literature dealing with the use of irradiation, at different doses and postoperative intervals, as a method to prevent this complication. The results demonstrate the efficacy of radiotherapy in preventing ectopic bone formation, the need to begin its application within the first four days of surgical treatment and the fact that satisfactory results can be obtained with relatively low and, thus, theoretically innocuous doses. 17 refs

MiR-139-3p is related to left ventricular hypertrophy and cardiomyocyte apoptosis in two-kidney one-clip hypertensive rats

Directory of Open Access Journals (Sweden)

Yang Xiaomin

2015-01-01

Full Text Available MicroRNAs (miRNAs are important post-transcriptional regulators of gene expression in many physiological and pathological processes. Previous studies have reported the role of miR-139-3p in cancer. However, its specific roles and functions in the heart undergoing hypertrophy have yet to be fully elucidated. In the present study, a significant upregulation of miR-139-3p expression was demonstrated in the left ventricular myocardium of two-kidney one-clip (2K1C hypertensive rats using microarray and quantitative real-time PCR (qRT-PCR. Based on computational analysis, we observed that miR-139-3p can control the expression of mitogen-activated protein kinase 1 (MAPK1 as a target gene, which is essential for the induction of cardiac hypertrophy and cardiomyocyte apoptosis. This study provides first information that the highly expressed miR-139-3p might be closely involved in MAPK1-mediated cardiac hypertrophy and cardiomyocyte apoptotic processes in 2K1C rat.

Ectopic jejunal pacemakers and gastric emptying after Roux gastrectomy: Effect of intestinal pacing

The aims of this study were to determine whether ectopic pacemakers are present after meals in the Roux limbs of dogs after vagotomy and Roux gastrectomy, whether these pacemakers slow gastric emptying of liquids or solids, and whether abolishing the pacemakers with electric pacing might speed any slow emptying that occurs. In six dogs that underwent vagotomy and Roux gastrectomy and in four dogs that underwent vagotomy and Billroth gastrectomy (controls), myoelectric activity of the Roux limb or duodenum was measured during gastric emptying of a 500 kcal mixed meal of 99mTc-labeled cooked egg and 111In-labeled milk. Roux dogs were tested with and without pacing of the Roux limb. Roux dogs showed ectopic pacemaker in the Roux limb that drove the pacesetter potentials of the limb in a reverse, or orad, direction during 57% of the postprandial recordings. Billroth dogs had no ectopic pacemakers (p less than 0.05). Liquids emptied more slowly in Roux dogs (half-life (t1/2) = 121 +/- 15 minutes) than in Billroth dogs (t1/2 = 43 +/- 9 minutes; p less than 0.05), but solids emptied similarly in both groups of dogs (t1/2 approximately 8 hours). Pacing the Roux limb abolished the ectopic pacemakers, restored the slow emptying of liquids to the more rapid rate found in the Billroth dogs (t1/2: paced Roux, 72 +/- 15 minutes; Billroth, 43 +/- 9 minutes; p greater than 0.05) and did not change emptying of solids. The conclusion was that ectopic pacemakers present in the Roux limb after vagotomy and Roux gastrectomy drove the limb in a reverse direction and slowed emptying of liquids after the operation. The defect was corrected by pacing the Roux limb in a forward direction

To investigate the role of phosphatase of regenerating liver-3 (PRL-3) in the 17β-estradiol (E2)- and interleukin 6 (IL-6)-induced migration of endometrial stromal cells (ESCs) from ectopic endometrium. Ectopic endometrial tissues were collected from patients with endometriosis, and PRL-3 expression in ectopic and eutopic endometrium was examined by immunohistochemistry. Endometrial stromal cells isolated from ectopic endometrium were treated with E2, progesterone (P), IL-6, or sodium orthovanadate (Sov) to inhibit PRL-3. Total RNA and protein were extracted from ESCs after treatment for quantitative real-time polymerase chain reaction and Western blot analyses. Cell migration was assessed using a scratch wound assay. Phosphatase of regenerating liver 3 protein was highly expressed in the endometrial glandular cells (EGCs) and ESCs in ectopic endometrium, whereas its weak expression was observed only in EGCs in eutopic endometrium. Both E2 and IL-6 treatment significantly increased PRL-3 messenger RNA and protein expression, and P treatment significantly inhibited PRL-3 expression. However, E2-induced PRL-3 expression in ESCs from ectopic endometrium was significantly blocked by IL-6 antibody. Moreover, E2- and IL-6-enhanced cell migration was completely abrogated by Sov treatment. Furthermore, Sov treatment could significantly promote PTEN expression but inhibit E2- and IL-6-induced p-AKT activation. Phosphatase of regenerating liver 3 plays a key role in the E2- and IL-6-induced migration of ESCs from ectopic endometrium, a process that is involved in the PTEN-AKT signaling pathway. © The Author(s) 2016.

Standard ultrasonography is often insensitive for distinguishing normal vs. diseased states for canine abdominal organs. Ultrasonographic elastography is a new technique that is becoming increasingly available and may help to improve sensitivity. This study evaluated the feasibility, repeatability, and reproducibility of strain elastography of the liver, spleen, kidneys, and prostate in healthy dogs and described the elasticity of each organ using strain values and strain ratios. The reproducibility of strain elastography was excellent, and intraobserver repeatability was moderate to excellent. The strain value of each organ was not significantly different among dogs (liver = 143.38 ± 7.41, spleen = 141.04 ± 9.03, left renal cortex = 141.26 ± 7.50, right renal cortex = 145.80 ± 7.79, and prostate = 135.46 ± 5.80), except for the renal medulla (left = 51.19 ± 4.54 and right = 51.93 ± 5.09) (P spleen, renal cortex, and prostate were similar with no significant difference (liver = 10.20 ± 1.47, spleen = 8.40 ± 1.53, left renal cortex = 9.62 ± 1.56, right renal cortex = 8.29 ± 1.63, and prostate = 8.20 ± 1.21), except for the renal medulla (left = 3.48 ± 0.68 and right = 2.95 ± 0.63) (P spleen, kidneys, and prostate.

Acute Abdomen in Interstitial Ectopic Pregnancy, An Emergency Laparoscopic Treatment

Directory of Open Access Journals (Sweden)

E. Picardo

2014-01-01

Full Text Available The present case report demonstrates a laparoscopic approach to treat interstitial cornual pregnancy in emergency. Interstitial ectopic pregnancy develops in the uterine portion of the fallopian tube which accounts for 2–4% of all ectopic pregnancies and has the potential to cause life-threatening hemorrhage at rupture. The mortality rate for a woman diagnosed with such a pregnancy is 2–2.5%. Diagnosis of interstitial pregnancy is made by ultrasound. In this case a 32 year-old woman, Gravida 0 Parity 0 Living 0 Ectopic 1, presented to the emergency obstetrical room complaining acute abdominal pain. There was a history of 10 weeks of pregnancy but no pelvic ultrasound scan was performed before the access. A transvaginal ultrasound scan immediately performed demonstrated a gestational sac with viable fetus in the right interstitial region. Moreover there was an ultrasound evidence of hemoperitoneum. She was transferred to the operating room and an emergency laparoscopy surgery was performed. The postoperative course was uneventful and the patient was discharged two days after the surgery. Interstitial pregnancies present a difficult management problem with no absolute standard of care in literature. Laparoscopic technique is under study with favorable results. For our personal point of view a treatment via laparoscopy could be performed both in elective and in emergency cases.

Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”. Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors which have a significant activity against aggressive pituitary or ectopic tumors.

Recent studies have suggested the existence of osteoblastic cells in the circulation, but the origin and role of these cells in vivo are not clear. Here, we examined how these cells contribute to osteogenesis in a bone morphogenetic protein (BMP)-induced model of ectopic bone formation. Following lethal dose-irradiation and subsequent green fluorescent protein-transgenic bone marrow cell-transplantation (GFP-BMT) in mice, a BMP-2-containing collagen pellet was implanted into muscle. Three weeks later, a significant number of GFP-positive osteoblastic cells were present in the newly generated ectopic bone. Moreover, peripheral blood mononuclear cells (PBMNCs) from the BMP-2-implanted mouse were then shown to include osteoblast progenitor cells (OPCs) in culture. Passive transfer of the PBMNCs isolated from the BMP-2-implanted GFP-mouse to the BMP-2-implanted nude mouse led to GFP-positive osteoblast accumulation in the ectopic bone. These data provide new insight into the mechanism of ectopic bone formation involving bone marrow-derived OPCs in circulating blood

Full Text Available We report a case of a congenital seminal vesicle cyst with ipsilateral hypoplastic kidney in a 51 year-old Indian man presenting with features of bladder outlet obstruction. Abdominal and pelvic Ultrasonography (USG, computed tomography revealed a retrovesical cystic mass measuring 10cm x 9cm with indentations over the left infero-lateral wall of the urinary bladder. On USG and radionuclide renal scanning the ipsilateral kidney was not found, which was located only on the CT scan. The cyst and the hypoplastic kidney was excised with an uneventful recovery.

Full Text Available Our objective was to investigate the miRNA profile of embryonic tissues in ectopic pregnancies (EPs and controlled abortions (voluntary termination of pregnancy; VTOP. Twenty-three patients suffering from tubal EP and twenty-nine patients with a normal ongoing pregnancy scheduled for a VTOP were recruited. Embryonic tissue samples were analyzed by miRNA microarray and further validated by real time PCR. Microarray studies showed that four miRNAs were differentially downregulated (hsa-mir-196b, hsa-mir-30a, hsa-mir-873, and hsa-mir-337-3p and three upregulated (hsa-mir-1288, hsa-mir-451, and hsa-mir-223 in EP compared to control tissue samples. Hsa-miR-196, hsa-miR-223, and hsa-miR-451 were further validated by real time PCR in a wider population of EP and control samples. We also performed a computational analysis to identify the gene targets and pathways which might be modulated by these three differentially expressed miRNAs. The most significant pathways found were the mucin type O-glycan biosynthesis and the ECM-receptor-interaction pathways. We also checked that the dysregulation of these three miRNAs was able to alter the expression of the gene targets in the embryonic tissues included in these pathways such as GALNT13 and ITGA2 genes. In conclusion, analysis of miRNAs in ectopic and eutopic embryonic tissues shows different expression patterns that could modify pathways which are critical for correct implantation, providing new insights into the understanding of ectopic implantation in humans.

The centromere-specific histone variant CENP-A (CID in Drosophila) is a structural and functional foundation for kinetochore formation and chromosome segregation. Here, we show that overexpressed CID is mislocalized into normally non-centromeric regions in Drosophila tissue culture cells and animals. Analysis of mitoses in living and fixed cells reveals that mitotic delays, anaphase bridges, chromosome fragmentation, and cell and organismal lethality are all direct consequences of CID mislocalization. In addition, proteins that are normally restricted to endogenous kinetochores assemble at a subset of ectopic CID incorporation regions. The presence of microtubule motors and binding proteins, spindle attachments, and aberrant chromosome morphologies demonstrate that these ectopic kinetochores are functional. We conclude that CID mislocalization promotes formation of ectopic centromeres and multicentric chromosomes, which causes chromosome missegregation, aneuploidy, and growth defects. Thus, CENP-A mislocalization is one possible mechanism for genome instability during cancer progression, as well as centromere plasticity during evolution.

Full Text Available Acute kidney injury (AKI is associated with significant morbidity and mortality in hypertensive surroundings. We investigated superoxide radical molecules influence on systemic haemodynamic and kidney function in spontaneously hypertensive rats (SHR with induced postischemic AKI. Experiment was performed in anesthetized adult male SHR. The right kidney was removed, and left renal artery was subjected to ischemia by clamping for 40 minutes. The treated group received synthetic superoxide dismutase mimetic TEMPOL in the femoral vein 5 minutes before, during, and 175 minutes after the period of reperfusion, while the control AKI group received the vehicle via the same route. All parameters were measured 24 h after renal reperfusion. TEMPOL treatment significantly decreased mean arterial pressure and total peripheral resistance P<0.05 compared to AKI control. It also increased cardiac output and catalase activity P<0.05. Lipid peroxidation and renal vascular resistance were decreased in TEMPOL P<0.05. Plasma creatinine and kidney morphological parameters were unchanged among TEMPOL treated and control groups. Our study shows that superoxide radicals participate in haemodynamic control, but acute superoxide scavenging is ineffective in glomerular and tubular improvement, probably due to hypertension-induced strong endothelial dysfunction which neutralizes beneficial effects of O2− scavenging.

The sonographic features of ectopic pregnancy have been well documented. When an early intrauterine pregnancy is identified or an obvious extrauterine sac is visualized, diagnosis is not a problem; but often a sac is seen within the uterus that may contain a well-defined rind and even internal echoes simulating an early fetal pole. This has been mistaken for an early intrauterine pregnancy. In this review, four patients with pseudogestational sacs had internal echoes within the sac, and two of them ultimately underwent dilatation and curettage, which revealed blood clots. This supports the assertion that fetal cardiac activity and/or fetal motion should be demonstrated within a fetal pole before the diagnosis of ectopic pregnancy is excluded.

Flax lignan concentrate attenuate hypertension and abnormal left ventricular contractility via modulation of endogenous biomarkers in two-kidney-one-clip (2K1C hypertensive rats

Full Text Available ABSTRACT The present investigation was designed to study the effect of flax lignan concentrate obtained from Linum usitatissimum L., Linaceae, in two-kidney, one clip (2K1C hypertension model in Wistar rats. 2K1C Goldblatt model rats were divided randomly into six groups: sham, 2K1C control, captopril (30 mg/kg, flax lignan concentrate (200, 400 and 800 mg/kg. Flax lignan concentrate and captopril were administered daily for eight consecutive weeks. Sham-operated, and 2K1C control rats received the vehicle. Treatment with flax lignan concentrate (400 and 800 mg/kg significantly and dose-dependently restored the hemodynamic parameters systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and left ventricular functions. The flax lignan concentrate significantly restored the elevated hepatic, renal and cardiac marker enzymes in the serum. It also restored the organs weights (kidney and heart, serum electrolyte level and histological abnormalities. Furthermore, flax lignan concentrate significantly elevated the level of biochemical markers that is enzymatic antioxidants superoxide dismutase, glutathione and decreased malondialdehyde in the heart and kidney tissues. Meanwhile, we found that plasma nitric oxide and plasma nitric oxide synthase contents were significantly increased in the flax lignan concentrate-treated group, and plasma endothelin-1 and renal angiotensin-II levels were significantly lower than 2K1C hypertensive group. In conclusion, the antihypertensive and antioxidant effect of flax lignan concentrate were dose-dependent and at the highest dose (i.e. 800 mg/kg similar to those of captopril (30 mg/kg. It is suggested that flax lignan concentrate reduced blood pressure by reduction of renal angiotensin-II level, inhibition of plasma endothelin-1 production, induction of the nitric oxide, nitric oxide synthase and in vivo antioxidant defense system.

Vinorelbine Potently Induces Placental Cell Death, Does Not Harm Fertility and is a Potential Treatment for Ectopic Pregnancy

Full Text Available Ectopic pregnancies complicate 1–2 pregnancies and are a leading cause of maternal death. An effective oral drug therapy that replaces surgery might make its treatment safer, cheaper, simpler and therefore more widely accessible. The only current medical treatment offered to women is intramuscular methotrexate, but this only reliably resolves smaller ectopic pregnancies. As such, many ectopic pregnancies require surgical excision. We show that vinorelbine, an orally available chemotherapeutic agent, potently induced placental cell death but did not harm fertility in mice. Vinorelbine was 100–1000 times more potent than methotrexate in inducing placental cell death in vitro, and more potent than combination methotrexate and gefitinib (another proposed treatment for ectopic pregnancy being evaluated in phase III trials. Mechanistically, it caused microtubule condensation, blocked mitosis and activated the apoptosis cascade in placental cells. Vinorelbine was more efficacious than methotrexate ± gefitinib in reducing the volume of placental cell tumors xenografted subcutaneously in SCID mice. Mice exposed to vinorelbine and allowed to breed, following a four week washout period, displayed normal fertility, however long-term fertility was not assessed. Human Fallopian tubes treated with vinorelbine did not exhibit up-regulation of apoptosis molecules. Our findings show that placental cells appear sensitive to vinorelbine and it has potential as a tablet-only approach to treat ectopic pregnancy.

An ectopic opening of the common bile duct into the duodenal bulb is a very rare congenital malformation of the bile duct, which may cause a recurrent duodenal ulcer or biliary diseases including choledocholithiasis or cholangitis. ERCP plays major role in the diagnosis of this biliary malformation. We report a case of an ectopic opening of the common bile duct into the duodenal bulb, which was detected on the upper gastrointestinal series.

2017-03-01

Full Text Available Case summary This report describes a rare case of crossed fused renal ectopia (CFRE in a cat. A mature intact male Persian cat presented with bloody nasal discharge and ascites. Diagnostic studies revealed an ectopic left kidney fused with an orthotopic right kidney and a concurrent feline infectious peritonitis (FIP infection. The FIP was responsible for clinical signs in this cat, while clinical signs associated with CFRE were not obvious. Despite receiving intensive treatment, the cat died. A post-mortem examination was not performed because the owners declined approval. Relevance and novel information To the best of our knowledge, this is the first report of L-shaped CFRE in a cat. In addition, this report describes the CT features of L-shaped CFRE in a cat.

Living kidney donor evaluation commonly includes nuclear renography to assess split kidney function and computed tomography (CT) scan to evaluate anatomy. To streamline donor workup and minimize exposure to radioisotopes, we sought to assess the feasibility of using proportional kidney volume from CT volumetry in lieu of nuclear renography. We examined the correlation between techniques and assessed their ability to predict residual postoperative kidney function following live donor nephrectomy. In a cohort of 224 live kidney donors, we compared proportional kidney volume derived by CT volumetry with split kidney function derived from nuclear renography and found only modest correlation (left kidney R(2) =26.2%, right kidney R(2) =26.7%). In a subset of 88 live kidney donors with serum creatinine measured 6 months postoperatively, we compared observed estimated glomerular filtration rate (eGFR) at 6 months with predicted eGFR from preoperative imaging. Compared to nuclear renography, CT volumetry more closely approximated actual observed postoperative eGFR for Chronic Kidney Disease Epidemiology Collaboration (J-test: P=.02, Cox-Pesaran test: P=.01) and Mayo formulas (J-test: P=.004, Cox-Pesaran test: Pvolumetry for estimation of split kidney function in healthy individuals with normal kidney function and morphology. © 2016 John Wiley & Sons A/S.

Objective: longitudinal study with B-mode ultrasonography and Doppler ultrasonography of maternal kidneys and liver in low-risk pregnancy, to establish and quantify normality parameters, correlating them with physiological changes. Materials and methods: twenty-five pregnant women were assessed and selected to participate in the study, each of them undergoing four examinations at the first, second, third trimesters and postpartum. Results: findings during pregnancy were the following: increased renal volume, pyelocaliceal dilatation with incidence of 45.4% in the right kidney, and 9% in the left kidney; nephrolithiasis, 18.1% in the right kidney, 13.6% in the left kidney. With pyelocaliceal dilatation, mean values for resistivity index were: 0.68 for renal arteries; 0.66 for segmental arteries; 0.64 for interlobar arteries; 0.64 for arcuate arteries. Without pyelocaliceal dilatation, 0.67 for renal arteries; 0.64 for segmental arteries; 0.63 for interlobar arteries; and 0.61 for arcuate arteries. Portal vein flow velocities presented higher values in pregnancy, with mean value for maximum velocity of 28.9 cm/s, and 22.6 cm/s postpartum. The waveform pattern of the right hepatic vein presented changes persisting in the postpartum period in 31.8% of the patients. Cholelithiasis was observed in 18.1% of the patients. Conclusion: alterations in renal volume, pyelocaliceal dilatation, nephrolithiasis, cholelithiasis, changes in portal vein flow velocity, alterations in waveform pattern of the right hepatic vein, proved to be significant.

Full Text Available Thirty pairs of kidneys of wild boar (Sus scrofa were studied from adult males, with permission from the Brazilian Institute of the Environment (Process nº 02001.003237/05, aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal; the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25% between the right and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.

Ectopic breast tissue, which includes both supernumerary breast and aberrant breast tissue, is the most common congenital breast abnormality. Ectopic breast cancers are rare neoplasms that occur in 0.3% to 0.6% of all cases of breast cancer. We retrospectively report, using a large series of breast abnormalities diagnosed and treated, our clinical experience on the management of the ectopic breast cancer. In 2 decades, we observed 327 (2.7%) patients with ectopic breast tissue out of a total of 12,177 subjects undergoing a breast visit for lesions. All patients were classified into 8 classes, according to the classification of Kajava, and assessed by a physician examination, ultrasounds, and, when appropriate, further studies with fine needle aspiration cytology and mammography. All specimens were submitted to the anatomo-pathologist. The most frequent benign histological diagnosis was fibrocystic disease. A rare granulosa cell tumor was also found in the right anterior thoracic wall of 1 patient. Four malignancies were also diagnosed in 4 women: an infiltrating lobular cancer in 1 patient with a lesion classified as class I, and an infiltrating apocrine carcinoma, an infiltrating ductal cancer, and an infiltrating ductal cancer with tubular pattern, occurring in 3 patients with lesions classified as class IV. Only 1 recurrence was observed. We recommend an earlier surgical approach for patients with lesions from class I to IV. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Our aim was to evaluate the relationship between the success of methotrexate treatment and β-hCG levels in progressive tubal ectopic pregnancies. We defined a retrospective cohort of 394 progressive tubal ectopic pregnancy patients treated with methotrexate. A single-dose methotrexate protocol using 50 mg/m2 was administered to patients with progressive tubal ectopic pregnancy. Surgery was performed in patients who exhibited signs of acute abdomen due to tubal rupture. Of 394 patients that received methotrexate treatment, 335 (84.6% responded to medical treatment, while the remaining 59 (15.36% underwent surgery due to treatment failure. β-hCG levels in the failure group were significantly higher as compared with the success group at Day 1, Day 4, and Day 7 (2116±3157 vs. 4178±3422, 2062±3551 vs. 4935±4103, and 1532±3007 vs. 3900±4783, respectively. The receiver operating characteristics curve for β-hCG levels at Day 1 was 0.738, with a cutoff value of 1418 mIU/mL, while sensitivity and specificity values reached the optimum for treatment success (83.1% and 59.4%, respectively. Medical treatment with methotrexate achieved an 85.02% success rate for the treatment of progressive tubal ectopic pregnancy, while success rates for medical treatment decreased significantly when initial β-hCG levels were >1418 mIU/mL.

Low levels of LTR retrotransposon deletion by ectopic recombination in the gigantic genomes of salamanders.

Science.gov (United States)

Frahry, Matthew Blake; Sun, Cheng; Chong, Rebecca A; Mueller, Rachel Lockridge

2015-02-01

Across the tree of life, species vary dramatically in nuclear genome size. Mutations that add or remove sequences from genomes-insertions or deletions, or indels-are the ultimate source of this variation. Differences in the tempo and mode of insertion and deletion across taxa have been proposed to contribute to evolutionary diversity in genome size. Among vertebrates, most of the largest genomes are found within the salamanders, an amphibian clade with genome sizes ranging from ~14 to ~120 Gb. Salamander genomes have been shown to experience slower rates of DNA loss through small (i.e., genomes. However, no studies have addressed DNA loss from salamander genomes resulting from larger deletions. Here, we focus on one type of large deletion-ectopic-recombination-mediated removal of LTR retrotransposon sequences. In ectopic recombination, double-strand breaks are repaired using a "wrong" (i.e., ectopic, or non-allelic) template sequence-typically another locus of similar sequence. When breaks occur within the LTR portions of LTR retrotransposons, ectopic-recombination-mediated repair can produce deletions that remove the internal transposon sequence and the equivalent of one of the two LTR sequences. These deletions leave a signature in the genome-a solo LTR sequence. We compared levels of solo LTRs in the genomes of four salamander species with levels present in five vertebrates with smaller genomes. Our results demonstrate that salamanders have low levels of solo LTRs, suggesting that ectopic-recombination-mediated deletion of LTR retrotransposons occurs more slowly than in other vertebrates with smaller genomes.

Full Text Available Background: Junctional ectopic tachycardia occurs frequently after congenital cardiac surgery and can be a cause of increased morbidity and mortality. Dexmedetomidine (DEX is an a2 adrenoreceptor agonist, has properties of controlling tachyarrhythmia by regulating the sympatho-adrenal system. Objective: To evaluate the efficacy of DEX for control of junctional ectopic tachycardia after repair of Tetralogy of Fallot (TOF. Materials and Methods: Two hundred and twenty pediatric cardiac patients with TOFs were enrolled in a prospective randomized control study. Patients underwent correction surgery. They were divided into two groups, i.e., Group 1 (DEX and Group 2 (control. Heart rate, rhythm, mean arterial pressure (MAP were recorded after the anesthetic induction (T1, after termination of bypass (T2, after 04 hours (T3, and 08 hours after transferring the patient to intensive care unit (ICU; T4. Results: Heart rate was comparable between two groups before starting the drug but statistically significant after bypass until 08 hours after transferring the patient to ICU. Junctional ectopic tachycardia occurred more in Group-2 (20% as compared to Group-1 (9.09%; P = 0.022. Junctional ectopic tachycardia occurs early in Group-2 (0.14 ± 0.527 hours as compared to Group 1 (0.31 ± 1.29 hours; P = 0.042. The duration of junctional ectopic tachycardia was more prolonged in Group-2 (1.63 ± 3.64 hours as compared to Group-1 (0.382 ± 1.60 hours; P = 0.012. The time to withdraw from mechanical ventilation and ICU stay of Group 1 patient was less than of Group 2 patients (P = <0.001. Conclusion: DEX had a therapeutic role in the prevention of junctional ectopic tachycardia in patients undergoing repair for TOF.

Endothelial nitric oxide synthase single nucleotide polymorphism and left ventricular function in early chronic kidney disease.

Directory of Open Access Journals (Sweden)

Full Text Available Chronic kidney disease (CKD is associated with accelerated cardiovascular disease and heart failure. Endothelial nitric oxide synthase (eNOS Glu298Asp single nucleotide polymorphism (SNP genotype has been associated with a worse phenotype amongst patients with established heart failure and in patients with progression of their renal disease. The association of a cardiac functional difference in non-dialysis CKD patients with no known previous heart failure, and eNOS gene variant is investigated.140 non-dialysis CKD patients, who had cardiac magnetic resonance (CMR imaging and tissue doppler echocardiography as part of two clinical trials, were genotyped for eNOS Glu298Asp SNP retrospectively.The median estimated glomerular filtration rate (eGFR was 50 mls/min and left ventricular ejection fraction (LVEF was 74% with no overt diastolic dysfunction in this cohort. There were significant differences in LVEF across eNOS genotypes with GG genotype being associated with a worse LVEF compared to other genotypes (LVEF: GG 71%, TG 76%, TT 73%, p = 0.006. After multivariate analysis, (adjusting for age, eGFR, baseline mean arterial pressure, contemporary CMR heart rate, total cholesterol, high sensitive C-reactive protein, body mass index and gender GG genotype was associated with a worse LVEF, and increased LV end-diastolic and systolic index (p = 0.004, 0.049 and 0.009 respectively.eNOS Glu298Asp rs1799983 polymorphism in CKD patients is associated with relevant sub-clinical cardiac remodelling as detected by CMR. This gene variant may therefore represent an important genetic biomarker, and possibly highlight pathways for intervention, in these patients who are at particular risk of worsening cardiac disease as their renal dysfunction progresses.

Use of a radioreceptorassay of human chorionic gonadotropin for the diagnosis and management of ectopic pregnancy

Saxena, B.B.; Landesman, R.

1975-01-01

The radioreceptorassay of human chorionic gonadotropin (hCG), with a sensitivity of 50 pg or 3 mIU/ml of plasma, has provided almost 100 percent reliability in detecting pregnancy after the first missed cycle. This test may be performed within 1 hour and is ideally suited to the clinical detection of ectopic pregnancy, especially in patients who require immediate surgical intervention. Thirteen patients with suspected ectopic pregnancy were evaluated by the radioreceptorassay, one of whom was followed with four separate determinations. The results of the assay were subsequently compared with those of hemagglutination pregnancy tests, clinical symptoms, and pathologic findings. All of the patients were diagnosed accurately by the radioreceptorassay, even when hemagglutination tests yielded a false indication of pregnancy. By this assay, the hCG levels during ectopic pregnancies are generally lower than those found during a normal intrauterine pregnancy; in addition, pregnancy may be detected much earlier (prior to the rupture) than is possible by hemagglutination tests. Furthermore, the diagnosis of ectopic pregnancy may be excluded for patients admitted to the hospital with acute abdominal emergencies

Interstitial pregnancy is defined as any gestation that develops in the uterine portion of the fallopian tubes lateral to the round ligament. Interstitial pregnancies account for 2-4% of all ectopic pregnancies and have been reported to have an associated 2% to 2.5% maternal mortality rate. The traditional treatment for interstitial pregnancy using surgical cornual resection may cause infertility or uterine rupture in subsequent pregnancies. Recently, the early identification of intact interstitial pregnancy has been made possible in many cases with high resolution transvaginal ultrasound as well as more sensitive assays for betahuman chorionic gonadotropin (β-hCG). The treatment includes: hysteroscopic transcervical currettage, local and systemic methotrexate (MTX) therapy and prostaglandin or potassium chloride injection of the ectopic mass under sonographic guidance. We describe a case of successful treatment of interstitial pregnancy using uterine artery embolization, after failure of methotrexate treatment

The aim of the study was to describe the sonographic findings of hepatobiliary fascioliasis with extrahepatic expansion and ectopic lesions. The study included 45 patients with fascioliasis. All diagnoses were confirmed via serologic enzyme-linked immunosorbent assays. Sonographic findings in the hepatobiliary system, extrahepatic expansion, and ectopic lesions were defined. The most common hepatic lesions were subcapsular localized, small, confluent, multiple hypoechoic nodules with poorly defined borders. We also detected ectopic lesion in 5 patients (11.1%) and live parasites in the gallbladder and bile duct in 11 (24.4%). The large spectrum of entities in the differential diagnosis of hepatobiliary fascioliasis may lead to misdiagnosis and incorrect treatment. However, the diagnosis can be made when the characteristic sonographic features are seen, such as heterogeneity of the liver with multiple poorly defined hypoechoic-isoechoic lesions and multiple echogenic nonshadowing particles in the gallbladder or common bile ducts. Nonetheless, the differential diagnosis of fascioliasis versus other hepatic lesions may still be difficult. In these situations, pathologic confirmation should be performed to exclude the possibility of malignancy. © 2013 by the American Institute of Ultrasound in Medicine.

Full Text Available The implantation of the fertilized egg outside the uterine cavity leads to the development of ectopic pregnancy. The incidence of ectopic pregnancy is 1/100 births. The most common place of ectopic implantation of the fertilized ovum is the oviduct (98% with predilection for the ampullar part of the Fallopian tube. The aim of this study was to determine the predictive importance of beta-hCG and progesterone concentration compared to ultrasonographic finding in the ectopic pregnancy diagnosis.We examined 24 patients with ectopic pregnancies which we divided according to the days of amenorrhea into two groups: the first group with the total of 28 patients from 16–42 days and another group of 8 patients with amenorrhea longer than 42 days. The control group was comprised of 20 patients with vital intrauterine pregnancy, gestational age of 42-52 days. Blood samples for quantitative determination of hormones were collected on three occasions after 48 hours in the forenoon time in the examined and control group of pregnant women. Ultrasonographic examinations of all pregnant women were carried out immediately after blood sampling, with the trans-vaginal approach using "make loop" option, and measurements with an accuracy of 0.1 mm.Mean values for beta-hCG range from 698-1774 mlU/ml in the first group of pregnant women, and in the second group of 1896 mlU/ml to 4410 mlU/ml with a statistically significant difference compared to the values in the control group (p <0.001. The concentration of progesterone in the first group of women ranging from 41-70 nmol/l, and in the second group of 76-94 nmol/l which is also the statistically significant difference compared to the control group (p<0.002. We have shown that ultrasonographic finding with its parameters reliably predicts the values of biochemical parameters both in normal intrauterine pregnancy and in the case of ectopic pregnancy.Embryo viability and implantation place condition the values of

Only a few cases are caused by vasculitis. We report here the first case of spontaneous rupture of kidney resulting from mixed cryoglobulinemia. Case presentation: A 44-year-old man presented with sudden onset of fever, acute pulmonary edema, left flank abdominal pain unassociated with trauma, and rapidly progressive renal failure requiring dialysis. Computed tomography of the abdomen revealed a large perirenal hematoma of the left kidney. During conservative surgery, the patient underwent renal biopsy that showed renal vasculitis and membranoproliferative glomerulonephritis with intracapillary microthrombi. Tests were positive for mixed cryoglobulinemia caused by Sjögren's syndrome. The patient was better after immunosuppressive therapy, with the disappearance of clinical symptoms and the recovery of baseline renal function. Conclusion: We report on this case and discuss a possible link between spontaneous rupture of kidney and mixed cryoglobulinemia-associated Sjögren's syndrome.

The effect of added sugar intake on ectopic fat accumulation is a subject of debate. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to examine the potential effect of added sugar intake on ectopic fat depots. MEDLINE, CAB Abstracts, CAB Global Health, and EBM (Evidence-Based Medicine) Reviews - Cochrane Central Register of Controlled Trials databases were searched for studies published from 1973 to September 2014. RCTs with a minimum of 6 days' duration of added sugar exposure in the intervention group were selected. The dosage of added sugar intake as a percentage of total energy was extracted or calculated. Means and standard deviations of pre- and post-test measurements or changes in ectopic fat depots were collected. Fourteen RCTs were included. Most of the studies had a medium to high risk of bias. Meta-analysis showed that, compared with eucaloric controls, subjects who consumed added sugar under hypercaloric conditions likely increased ectopic fat, particularly in the liver (pooled standardized mean difference = 0.9 [95%CI, 0.6-1.2], n = 6) and muscles (pooled SMD = 0.6 [95%CI, 0.2-1.0], n = 4). No significant difference was observed in liver fat, visceral adipose tissue, or muscle fat when isocaloric intakes of different sources of added sugars were compared. Data from a limited number of RCTs suggest that excess added sugar intake under hypercaloric diet conditions likely increases ectopic fat depots, particularly in the liver and in muscle fat. There are insufficient data to compare the effect of different sources of added sugars on ectopic fat deposition or to compare intake of added sugar with intakes of other macronutrients. Future well-designed RCTs with sufficient power and duration are needed to address the role of sugars on ectopic fat deposition. © The Author(s) 2015.

2014-09-05

In myasthenia gravis (MG) both native and ectopic thymic tissue containing germinal centers should show greater metabolism compared to adjacent tissues. We evaluated whether preoperative standardized uptake value (SUV) of 18fluoro-deoxy-glucose on Positron Emission Tomography (PET) might be increased and correlated with the presence of native or ectopic germinal centers. From 2005 to 2012 we performed extended thymectomy in 68 patients with non-thymomatous MG. All patients underwent PET-scan preoperatively and one-year postoperatively. SUVs were assessed in thymic and perithymic regions. Then it was matched with same-age, non-MG and non-neoplastic control group and finally correlated with presence of germinal centers in native thymus or in the ectopic tissue found in the surgical specimens. Mean SUV was significantly increased in MG patients compared to control group. Thymic SUV was significantly higher in presence of thymic germinal centers [3.5 (2.4-5.0) Vs 2.1 (1.4-2.5), p = 0.021] while perithymic SUV was significantly higher in presence of ectopic germinal centers [3.1 (2.7-3.5) Vs 1.3 (0.9-1.7), p = 0.001]. SUV was significantly correlated with MG score (rho = 0.289, p = 0.017) and marginally with antibodies anti-acetylcholine receptors (rho = 0.129, p = 0.05). At Kaplan Meier analysis, ectopic thymic tissue (p = 0.045) and ectopic germinal centers (p = 0.036) were significant predictors of complete stable remission, but preoperative dichotomized thymic (3.5 or more Vs less) (p = 0.083) and perithymic (2.1 or more Vs less) (p = 0.052) SUVs did not. Thymic and perithymic SUVs were significantly higher in patients with MG than non-MG and non-neoplastic patients. Thymic SUV was significantly correlated with the presence of germinal centers. Perithymic SUV resulted significantly correlated with the discovery of ectopic active thymic tissue. Neither thymic nor perithymic high SUVs predicted remission.

Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only rare cases of ectopic PTC without any evidence of occult thyroid cancer in the orthotopic thyroid or cervical lymph nodes have been reported. We report on a 39 year old woman who was operated for a mediastinal mass. The initial diagnosis was a malignant thymic lesion, which was later confirmed to be a papillary thyroid carcinoma. Consequently, total thyroidectomy was performed and pathology report showed normal thyroid tissue with no evidence of any neoplastic involvement. Until now, only one similar case has been reported

Full Text Available When Clifford Grobstein set out to study the inductive interaction between tissues in the developing embryo, he developed a method that remained important for the study of renal development until now. From the late 1950s on, in vitro cultivation of the metanephric kidney became a standard method. It provided an artificial environment that served as an open platform to study organogenesis. This review provides an introduction to the technique of organ culture, describes how the Grobstein assay and its variants have been used to study aspects of mesenchymal induction, and describes the search for natural and chemical inducers of the metanephric mesenchyme. The review also focuses on renal development, starting with ectopic budding of the ureteric bud, ureteric bud branching, and the generation of the nephron and presents the search for stem cells and renal progenitor cells that contribute to specific structures and tissues during renal development. It also presents the current use of Grobstein assay and its modifications in regenerative medicine and tissue engineering today. Together, this review highlights the importance of ex vivo kidney studies as a way to acquire new knowledge, which in the future can and will be implemented for developmental biology and regenerative medicine applications.

Elevated dietary magnesium during pregnancy and postnatal life prevents ectopic mineralization in Enpp1asj mice, a model for generalized arterial calcification of infancy.

Generalized arterial calcification of infancy (GACI) is an autosomal recessive disorder caused by mutations in the ENPP1 gene. It is characterized by mineralization of the arterial blood vessels, often diagnosed prenatally, and associated with death in early childhood. There is no effective treatment for this devastating disorder. We previously characterized the Enpp1asjmutant mouse as a model of GACI, and we have now explored the effect of elevated dietary magnesium (five-fold) in pregnant mothers and continuing for the first 14 weeks of postnatal life. The mothers were kept on either control diet or experimental diet supplemented with magnesium. Upon weaning at 4 weeks of age the pups were placed either on control diet or high magnesium diet. The degree of mineralization was assessed at 14 weeks of age by histopathology and a chemical calcium assay in muzzle skin, kidney and aorta. Mice placed on high magnesium diet showed little, if any, evidence of mineralization when their corresponding mothers were also placed on diet enriched with magnesium during pregnancy and nursing. The reduced ectopic mineralization in these mice was accompanied by increased calcium and magnesium content in the urine, suggesting that magnesium competes calcium-phosphate binding thereby preventing the mineral deposition. These results have implications for dietary management of pregnancies in which the fetus is suspected of having GACI. Moreover, augmenting a diet with high magnesium may be beneficial for other ectopic mineralization diseases, including nephrocalcinosis.

There is strong evidence that fat accumulating in non-adipose sites, "ectopic fat", is associated with cardiovascular disease (CVD), including vascular calcification. Most previous studies of this association have assessed only a single ectopic fat depot. Therefore, our aim was to assess the association of total, regional, and ectopic fat with abdominal aorto-illiac calcification (AAC) and coronary artery calcification (CAC) in 798 African ancestry men. Participants (mean age 62) were from the Tobago Bone Health Study cohort. Adiposity was assessed via clinical examination, dual x-ray absorptiometry, and computed tomography (CT). Ectopic fat depots included: abdominal visceral adipose tissue (VAT), liver attenuation, and calf intermuscular adipose tissue (IMAT). Vascular calcification was assessed by CT and quantified as present versus absent. Associations were tested using multiple logistic regression adjusted for traditional cardiovascular risk factors. Models of ectopic fat were additionally adjusted for total body fat and standing height. All adiposity measures, except VAT, were associated with AAC. Lower liver attenuation or greater calf IMAT was associated with 1.2-1.3-fold increased odds of AAC (p fat measure was associated with CAC. Greater adiposity in the skeletal muscle and liver, but not in the visceral compartment, was associated with increased odds of AAC in African ancestry men. These results highlight the potential importance of both quantity and location of adiposity accumulation throughout the body. Copyright © 2017 Elsevier B.V. All rights reserved.

The undetectable supernumerary and ectopic parathyroid glands have a high risk of persistent and recurrent hyperparathyroidism, especially in the patients with secondary hyperparathyroidism. Preoperative image diagnosis, CT scan, echogram and 201 TlCl scintigram were very useful for detecting supernumerary and ectopic parathyroid glands in our 132 patients who underwent parathyroidectomy for secondary hyperparathyroidism. Among these methods the scintigraphy showed the highest detection rate of the glands located in the thyroid gland and those located between the thyroid gland and trachea. The echography was useful in detecting the glands in the thyroid gland, but could not offer easy visualization those located in the mediastinum. Even the ectopic parathyroid glands, weighing more than 500 mg were identifiable at about 90% when all the methods were applied routinely. In our experience, four patients had a supernumerary gland which was detected by the preoperative image diagnostic procedures at the initial surgery. One patient had a supernumerary gland in the mediastinum which was detected by image diagnosis after the initial operation and was removed at reoperation. (author)

Ectopic adrenocorticotropic hormone (ACTH) is rarely secreted by neuroendocrine tumors. Although neuroendocrine tumors may occur at any site in the gastrointestinal system, they very rarely occur in the ampulla of Vater and have a poor prognosis. The present study described the first Cushing's syndrome as a result of ectopic ACTH arising from the ampulla of Vater neuroendocrine carcinoma. A 69-year-old female was admitted with clinical features of Cushing's syndrome, confirmed biochemically by hypokalemia, and elevated levels of ACTH and cortisol. In further investigations, a tumor of the ampulla of Vater and liver metastases were detected. Pathological analysis of the biopsy confirmed a neuroendocrine carcinoma, which was immunohistochemically positive for chromogranin A, synaptophysin, cluster of differentiation 56 and ACTH. Therefore, the present study diagnosed a functional and metastatic neuroendocrine carcinoma of the ampulla of Vater with ectopic ACTH production causing Cushing's syndrome. The patient succumbed to mortality 4 months later, despite administration of combined chemotherapy with irinotecan and cisplatin.

Ectopic osteoid and bone formation by three calcium-phosphate ceramics in rats, rabbits and dogs.

Directory of Open Access Journals (Sweden)

Liao Wang

Full Text Available Calcium phosphate ceramics with specific physicochemical properties have been shown to induce de novo bone formation upon ectopic implantation in a number of animal models. In this study we explored the influence of physicochemical properties as well as the animal species on material-induced ectopic bone formation. Three bioceramics were used for the study: phase-pure hydroxyapatite (HA sintered at 1200°C and two biphasic calcium phosphate (BCP ceramics, consisting of 60 wt.% HA and 40 wt.% TCP (β-Tricalcium phosphate, sintered at either 1100°C or 1200°C. 108 samples of each ceramic were intramuscularly implanted in dogs, rabbits, and rats for 6, 12, and 24 weeks respectively. Histological and histomorphometrical analyses illustrated that ectopic bone and/or osteoid tissue formation was most pronounced in BCP sintered at 1100°C and most limited in HA, independent of the animal model. Concerning the effect of animal species, ectopic bone formation reproducibly occurred in dogs, while in rabbits and rats, new tissue formation was mainly limited to osteoid. The results of this study confirmed that the incidence and the extent of material-induced bone formation are related to both the physicochemical properties of calcium phosphate ceramics and the animal model.

To explore the value of combined detection of serum β-HCG and P in diagnosis of early ectopic pregnancy and expectant therapeutic efficacy. Serum levels of β-HCG and P of 324 patients with early ectopic pregnancy and 146 normal early pregnant women were determined and compared by RIA, Serum β-HCG and P were compared between before and after treatment. The required time when serum β-HCG and P decreased to the normal rang of the patients treated successfully were observed respectively. The results showed that the serum β-HCG and P value in ectopic pregnancy group were significantly lower than those in intrauterine gestation group (P<0.05). The variation of P was significant between success and failure groups of drug conservative treatment, but β-HCG had no significant difference. The required time when serum P decreased to the normal was significantly less than the serum β-HCG dropped to normal. Combined detection of serum levels of β-HCG and P is an adjunctive method to diagnose early ectopic pregnancy, so it giants opportunity for treatment of early ectopic pregnancy and is of positive clinical application value for observation therapeutic effect and prognosis of the disease. P values may be one of the more important reference index to predict whether conservative treatment is successful or not than β-HCG. (authors)

Ectopic major transplantation for salvage of upper and lower extremity amputations

Directory of Open Access Journals (Sweden)

Nazerani Shahram

2013-12-01

Full Text Available 【Abstract】Objective: Ectopic tissue transplanta- tion is not a new idea. Godina and his colleagues pioneered this method in the 1980s. This method is a last resort method of preserving an amputated body part, which consists of banking the amputated segment in an ectopic area and re- turning it to its native place at a later date. In this article we present our experience with this demanding procedure. Methods: Debridement was the mainstay of this procedure. The stump and amputated part are carefully de- brided and the stump was either closed primarily or covered by a flap. The amputated part was transplanted to one of several banking sites in the body and at a later date it will be transferred to its native site in an elective setting. Results: Seven patients meeting the set criteria for ectopic transplantation were enrolled in this study. The over- all success rate was about 70%, lower than expected but these are cases of severe crush injury. Although the func- tional recovery of these patients are very low, all of the successful cases except one could find a job as a janitor or light manual worker. No patient could return to his previous job. Conclusion: Ectopic transplantation of body parts is an accepted method of treatment of severely crushed ex- tremity or finger injuries. In our country an amputee has very little chance of finding a job instead a disabled person can. In addition in Iran cultures amputation is seen as pu- nishment of either the God or the society, so it is not well accepted and many patients persist on saving the limb even with no functional recovery. None of our successful cases could return to his previous occupation but almost all of them could find a job as janitors or light manual workers.

Classically, the diagnosis of ectopic ureter was done in grown up girls due to urinary incontinence, today the diagnoses are more precocious, which has partially changed treatment. The objective of this paper is to perform a review of our experience over the last years and to correlate it with the current type of presentation. We studied all patients with the diagnosis of ectopic ureter in a period of 10 years, between 1997 and December 2006. Demographic characteristics, type of presentation, diagnostic tests performed, age at the time of diagnosis and treatment were all analyzed, altogether with the different techniques employed for treatment. We found 19 patients with this disease, 15 of them females. Type of presentation was febrile urinary tract infection in 13 patients, urinary incontinence in two, and prenatal diagnosis of hydronephrosis in 4. Sixteen children had double pyeloureteral systems and only three had single systems. In all cases the diagnosis was performed with renal-bladder ultrasound, urethrocystogram and endoscopic studies. Additional studies such as excretion pyelograms were performed in 8 patients at the start of the series and nuclear medicine tests in 17. Median age at the time of diagnosis was eight months. All patients underwent surgical treatment. In patients with double systems superior heminephroureterectomy was performed in 8 patients, vesicoureteral reimplantation in three and pyelopyelic anastomosis in three cases with upper pole remnant function. In another two cases nephroureterectomy was performed due to the presence of reflux to the lower or system and severe renal compromise. In all three cases with single systems ureter reimplantation was performed. Currently prenatal suspicion and adequate study of urinary tract infections enable confirmation of ectopic ureter. Few children debut with urinary incontinence currently, due to the precocity of diagnosis. Treatment is always surgical, and basically depends on renal function, and

To characterize the ultrasonographic findings of multicystic dysplastic kidney on prenatal ultrasonography (US) with a special emphasis on the distribution of cysts. From January 1998 to March 2003, medical records of sixty two subjects with multicystic dysplastic kidney diagnosed on prenatal US examination were retrospectively reviewed, and forty three patients confirmed either by pathology or postnatal follow-up US were selected for this study. US assessment included the time of diagnosis, laterality, size of the multicystic dysplastic and contralateral normal kidneys, distribution of cysts and associated anomalies. The distribution of cysts was categorized as subcapsular and random distribution, and interobserver agreement was determined using the cross table analysis. The largest multicystic and contralateral normal longitudinal diameters were measured, and the data were plotted on the normal reference chart. Multicystic dysplastic kidney was left sided in 55.8%, right sided in 34.8% and bilateral in 9.3%. Subcapsular distribution of cysts was observed in 68.2% (n=15) for radiologist 1 while 59.1% (n=13) for radiologist 2, showing an excellent interobserver agreement (k=0.697). The longitudinal diameter of the multicystic dysplastic kidney was above 95 percentile in 68%. Meanwhile, the diameter of the contralateral normal kidney was more commonly normal, 70%. Fetal karyotyping was done in 18 cases including 2 cases with associated major anomalies, but karyotyping was all normal. On prenatal US, subcapsular distribution of cysts in multicystic dysplastic kidney is more common than random distribution. This characteristic distribution of cysts may be helpful in the prenatal diagnosis of multicystic dysplastic kidney.

To characterize the ultrasonographic findings of multicystic dysplastic kidney on prenatal ultrasonography (US) with a special emphasis on the distribution of cysts. From January 1998 to March 2003, medical records of sixty two subjects with multicystic dysplastic kidney diagnosed on prenatal US examination were retrospectively reviewed, and forty three patients confirmed either by pathology or postnatal follow-up US were selected for this study. US assessment included the time of diagnosis, laterality, size of the multicystic dysplastic and contralateral normal kidneys, distribution of cysts and associated anomalies. The distribution of cysts was categorized as subcapsular and random distribution, and interobserver agreement was determined using the cross table analysis. The largest multicystic and contralateral normal longitudinal diameters were measured, and the data were plotted on the normal reference chart. Multicystic dysplastic kidney was left sided in 55.8%, right sided in 34.8% and bilateral in 9.3%. Subcapsular distribution of cysts was observed in 68.2% (n=15) for radiologist 1 while 59.1% (n=13) for radiologist 2, showing an excellent interobserver agreement (k=0.697). The longitudinal diameter of the multicystic dysplastic kidney was above 95 percentile in 68%. Meanwhile, the diameter of the contralateral normal kidney was more commonly normal, 70%. Fetal karyotyping was done in 18 cases including 2 cases with associated major anomalies, but karyotyping was all normal. On prenatal US, subcapsular distribution of cysts in multicystic dysplastic kidney is more common than random distribution. This characteristic distribution of cysts may be helpful in the prenatal diagnosis of multicystic dysplastic kidney.

Objective: The objective of this study was to see echocardiographic findings of cardiac dysfunction in patients of chronic kidney disease (CKD) on hemodialysis. Study Design: Comparative cross sectional study. Place and Duration of Study: Department of nephrology, Pakistan Institute of Medical Sciences. Islamabad from September 2014 to February 2015. Patients and Methods: One hundred patients of either gender were included in this study. Fifty patients of chronic kidney disease stage V on hemodialysis were taken for echocardiography and fifty were normal. Echocardiography was done for cardiac dysfunction. Systolic function was measured by ejection fraction (EF) and fractional shortening (FS). Diastolic function was measured by E/A ratio. Results: Out of 100 patients included in the study, 50 patients were on hemodialysis and 50 were control. Left ventricular end systolic and end diastolic volumes were higher in patients on hemodialysis than controls as well as left atrial enlargement and inter ventricular septum which was statistically significant. Ejection fraction, although normal and fractional shortening decreased in patients on hemodialysis (p<0.05). Diastolic dysfunction was present in 36 patients on hemodialysis, while absent in the control group. Conclusion: Patients with chronic kidney disease on hemodialysis have higher prevalence of cardiac dysfunction. (author)

Congenital atresia of the common and external iliac arteries is a rare vascular anomaly that may be associated with congenital renal or genitourinary malformations. In ESRD patients, its presence may pose potential problems during renal transplantation. We report a rare case of kidney transplantation in a patient with VACTERL syndrome who was found to have absent right common and external iliac arteries during pre-operative imaging. Vascular supply to the right lower limb is derived from an anomalous branch from the left internal iliac artery which takes on a convoluted course across the pelvis. Kidney transplantation was performed successfully with implantation performed on the left side. Isolated cases of congenital iliac artery atresia have been described in association with urological abnormalities but no clear association has yet been established. However, we feel that it may be useful to perform routine angiographic evaluation for ESRD patients with congenital genitourinary abnormalities being planned for kidney transplantation. While most cases of congenital iliac artery anomalies are symptomatic with claudication, some remain asymptomatic with normal physical examination findings. There is some evidence in literature suggesting the usefulness of routine pre-operative CT in a selective group of patients. Kidney transplantation in such cases is safe and we recommend routine pre-operative imaging of patients known to have congenital genitourniary abnormalities. The kidney should be implanted heterotopically to the contralateral side of the vascular anomaly and care must be taken to preserve vascular supply to the lower limbs. Copyright © 2015 The Authors.

Primary mesenchymal chondrosarcoma of the kidney: A case report and review of literature

Directory of Open Access Journals (Sweden)

Pedro Valente

2018-01-01

Full Text Available Primary mesenchymal chondrosarcoma of the kidney is extremely rare, with only nine cases reported in the English literature. We report a new case of this disease. A 35-year-old man, presented with flank pain, episodic gross hematuria and a painless palpable mass in left abdominal quadrant. Computed tomography scan identified a left renal tumor with 20 cm, with no evidence of regional or metastatic spread disease. The patient underwent radical nephrectomy. The immunohistopathological diagnosis was mesenchymal chondrosarcoma of the kidney. At 18 months of follow-up, there was no evidence of recurrence or distant metastasis. Primary renal chondrosarcoma is so rare that its prognosis is unknown. Disease recurrence is unpredictable and when it is detected, the prognosis is poor. The radical nephrectomy with complete resection of the tumor with wide resection free margins is recommended, and the patients need long-term and close surveillance, with particular attention to local recurrence and uncommon sites of metastization.

Ectopic mineralization disorders of the extracellular matrix of connective tissue: molecular genetics and pathomechanisms of aberrant calcification.

Li, Qiaoli; Jiang, Qiujie; Uitto, Jouni

2014-01-01

Ectopic mineralization of connective tissues is a complex process leading to deposition of calcium phosphate complexes in the extracellular matrix, particularly affecting the skin and the arterial blood vessels and common in age-associated disorders. A number of initiating and contributing metabolic and environmental factors are linked to aberrant mineralization in these diseases, making the identification of precise pathomechanistic pathways exceedingly difficult. However, there has been significant recent progress in understanding the ectopic mineralization processes through study of heritable single-gene disorders, which have allowed identification of discrete pathways and contributing factors leading to aberrant connective tissue mineralization. These studies have provided support for the concept of an intricate mineralization/anti-mineralization network present in peripheral connective tissues, providing a perspective to development of pharmacologic approaches to limit the phenotypic consequences of ectopic mineralization. This overview summarizes the current knowledge of ectopic heritable mineralization disorders, with accompanying animal models, focusing on pseudoxanthoma elasticum and generalized arterial calcification of infancy, two autosomal recessive diseases manifesting with extensive connective tissue mineralization in the skin and the cardiovascular system. © 2013.

Larsson, I.; Lindstedt, E.; Ohlin, P.; Strand, S.E.; White, T.

1975-01-01

A scintillation camera technique was used for measuring renal uptake of [ 131 I]Hippuran 80-110 s after injection. Externally measured Hippuran uptake was markedly influenced by kidney depth, which was measured by lateral-view image after injection of [ 99 Tc]iron ascorbic acid complex or [ 197 Hg]chlormerodrine. When one kidney was nearer to the dorsal surface of the body than the other, it was necessary to correct the externally measured Hippuran uptake for kidney depth to obtain reliable information on the true partition of Hippuran between the two kidneys. In some patients the glomerular filtration rate (GFR) was measured before and after nephrectomy. Measured postoperative GFR was compared with preoperative predicted GFR, which was calculated by multiplying the preoperative Hippuran uptake of the kidney to be left in situ, as a fraction of the preoperative Hippuran uptake of both kidneys, by the measured preoperative GFR. The measured postoperative GFR was usually moderately higher than the preoperatively predicted GFR. The difference could be explained by a postoperative compensatory increase in function of the remaining kidney. Thus, the present method offers a possibility of estimating separate kidney function without arterial or ureteric catheterization. (auth)

Ectopic penis is usually associated with penoscrotal transposition, and it is rarely observed in isolation. We report a surgical approach for an extremely rare case. A 10-year-old male patient with bilateral cryptorchidism and ectopic penis and scrotum in perineal area, with no penoscrotal transposition, representing an association not yet described in literature. A previous orchiopexy failed due to ectopic scrotum. By means of an inverted Y incision, the penis was mobilized and a perineal skin flap in form of a testicular sac was prepared. Finally orchiopexy was performed. The surgery was essential to treat cryptorchidism and to improve the self-image of the patient. RESUMO O pênis ectópico geralmente ocorre associado à transposição peno-escrotal, sendo raro isoladamente. Relatamos uma abordagem cirúrgica para um caso extremamente raro. Tratava-se de paciente do sexo masculino, 10 anos, com criptorquidia bilateral e pênis e escroto ectópicos, na região perineal, sem transposição peno-escrotal, representando uma associação ainda não descrita na literatura. Orquidopexia prévia sem sucesso, devido à ectopia do escroto. Por meio de uma incisão em Y invertido, mobilizou-se o pênis e preparou-se um retalho da pele perineal em forma de bolsa testicular. Por fim, realizou-se a orquidopexia. A cirurgia foi fundamental para tratar a criptorquidia e promover ganho na autoimagem do paciente.

Ectopic cervical thymoma mimicking as papillary thyroid carcinoma: A diagnostic dilemma

Directory of Open Access Journals (Sweden)

Thakur Abhijit

2010-04-01

Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

2015-04-26

Fibroadenoma of an accessory breast is a rare disease. The clinical significance lies in the fact that a number of cystic, inflammatory, neoplastic diseases similar to those of a normal breast have been reported in accessory breasts as well. Vigilant self-assessment and complete clinical examination are always encouraged to detect earliest malignancy in the axilla. We report two cases of ectopic breast fibroadenoma with the relevant literature. 2015 BMJ Publishing Group Ltd.

The rupture of ectopic pregnancy (EP) still remains the primary and direct cause of death in the first trimester of pregnancy. Ultrasonography is known to be a modality of choice in EP diagnostics. We found a severe discrepancy between the frequency of ectopic pregnancies (EP) and the number of available computed tomography (CT) examinations. A 29-year-old woman was admitted to the emergency department with a history of abdominal pain, nausea, vomiting and collapse. Sonographic findings of a suspected EP were unclear. Moreover, not all features of intrauterine pregnancy were present. Due to the patient’s life-threatening condition, an emergency multi-slice CT with MPR and VRT reconstructions was performed, revealing symptoms of a ruptured EP. In the right adnexal area, a well-vascularized, solid-cystic abnormal mass lesion was found. Intraperitoneal hemorrhage was confirmed intraoperatively, and the right fallopian tube with a tubal EP was resected. In the surgery in situ, as well as in the pathological examination of the tumor mass, a human embryo of approximately 1.5 cm in length (beginning of the 8 th week of gestation) was found. Although ultrasonography still remains the first-line imaging examination in EP diagnostics, sometimes the findings of suspected EPs are unclear and not sufficient. The rupture of EP, with serious bleeding and symptoms of shock, may require an emergent pelvic and abdominal CT inspection. A clear correlation was found between the macroscopic CT images and the intraoperatively sampled material

Testing Danegaptide Effects on Kidney Function after Ischemia/Reperfusion Injury in a New Porcine Two Week Model.

Directory of Open Access Journals (Sweden)

Chris Amdisen

Full Text Available Ischemia/reperfusion injury (I/R-I is a leading cause of acute kidney injury (AKI and is associated with increased mortality. Danegaptide is a selective modifier of the gap junction protein connexion 43. It has cytoprotective as well as anti-arrhythmic properties and has been shown to reduce the size of myocardial infarct in pigs. The aim of this study was to investigate the ischemia-protective effect of Danegaptide in a porcine renal I/R-I model with two weeks follow up.Unilateral renal I/R-I was induced in pigs by clamping the left renal artery over a two hour period. The model allowed examination of renal blood flow by magnetic resonance imaging (MRI and the measurement of single kidney GFR two weeks after injury. Eleven animals were randomized to Danegaptide-infusion while nine animals received placebo. Kidney histology and urinary neutrophil gelatinase-associated lipocalin (NGAL excretion were included as markers of AKI.Unilateral kidney I/R-I resulted in an immediate ~50% GFR reduction, associated with a four-fold increase in urinary NGAL-excretion. Fourteen days after I/R-I, the total GFR was ~75% of baseline with a significantly lower GFR in the injured left kidney compared to the right kidney. No differences in GFR were observed between the treated and non-treated animals immediately after I/R-I or at Day 14. Furthermore, no differences were observed in the urinary excretion of NGAL, renal blood flow or other markers of renal function.As expected this porcine renal I/R-I model was associated with reduced GFR two weeks after injury. Danegaptide did not improve renal function after I/R-I.

Endotracheal ectopic parathyroid adenoma mimicking asthma

Full Text Available Primary benign tumors of the trachea are uncommon. These tumors may cause tracheal occlusion and lead to a misdiagnosis of asthma. Ectopic parathyroid adenoma (EPA can be seen anywhere between the mandibular angle and the mediastinum. The distal part of the trachea is a rare location for EPA, and EPA obstructing the endotracheal lumen has not been reported in the literature. We herein describe a 52-year-old female with a several-year history of asthma treatment who presented with progressive dyspnea. Computed tomography revealed a mass that was obstructing the tracheal lumen. Total mass excision was performed via endobronchial treatment, and pathologic examination revealed EPA.

Determination of separate kidney clearance by means of the Tc-DTPA complex and the scintillation camera

International Nuclear Information System (INIS)

Piepsz, A.; Dobbeleir, A.; Erbsmann, F.

1975-01-01

A new quantitative method to determine the separate kidney is described. This method is based on the use of the Tc-DTPA complex administered in a single intraveinous injection, a scintillation camera and continuous computerized data recording for 20 minutes at 20 sec. intervals. By definition the slope of the kidney radioactivity curve, divided by the corresponding plasma concentration, represents at each instant the glomerular clearance of the kidney. This only applies before the 3rd minute following the intraveinous tracer injection, when the filtered radioactivity has not yet left the kidney area. Between the 60th and 180th sec., 6 clearance values may be determined for each kidney. For each 20-sec. time interval the renal activity increase per minute is divided by the plasma concentration during the same interval and the average of these values is taken as the glomerular clearance figure. Some results have been analysed. The test could end 3 min. after the intraveinous injection. Continuation of the recording for 20 min. gives a complete dynamic picture of the kidney function [fr

Lemke, U.; Taupitz, M.; Hamm, B.; Kroencke, T.J.; Kluener, C.; Giessing, M.; Schoenberger, B.

2008-01-01

Purpose: to evaluate contrast-enhanced 3D magnetic resonance angiography (CE-MRA) and digital subtraction angiography (DSA) in comparison with the intraoperative findings in living kidney donors. Materials and methods: a total of 156 kidneys in 78 potential kidney donors were prospectively examined using CE-MRA (0.2 mmol Gd/kg, voxel size 1.3 x 0.8 x 2.0) and DSA. Two experienced radiologists assessed the images in consensus regarding the renal vascular anatomy and variants. The results for the 67 candidates accepted for donation were compared to the intraoperative findings. In the other kidneys not accepted for donor nephrectomy, MRA and DSA were compared with each other. Results: nineteen arterial variants were identified intraoperatively, of which 11 (58%) were also detected by preoperative CE-MRA and 10 (53%) by preoperative DSA. Of the 10 venous variants found intraoperatively, CE-MRA detected 8 (80%) and DSA 3 (30%). The agreement (kappa test) between MRI and DSA for all 156 evaluated kidneys was 0.7 for arterial variants (McNemar p = 0.12) and 0.3 for venous variants (McNemar p = 0.01). The preoperative choice of kidney (right or left) made on the basis of the renal vascular anatomy seen on CE-MRA and DSA differed in 22% of the 78 potential donors (McNemar P = 0.3). (orig.)

Full Text Available 34-year-old man with chronic renal and pancreas failure in complicated diabetic disease received a kidney-pancreas transplantation. On the 32nd postoperative day, an acute kidney rejection occurred and resolved with OKT3 therapy. The patient also presented refractory urinary infection by E. Fecalis and M. Morganii, and a focal bronchopneumonia in the right-basal lobe resolved with elective chemotherapy. During the 50th post-operative day, an intense soft tissue inflammation localized in the first left metatarsal-phalangeal articulation occurred (Figure 1 followed by an abscess with a cutaneous fistula and extension to the almost totality of foot area. The radiological exam revealed a small osteo-lacunar image localized in the proximal phalanx head of the first finger foot. From the cultural examination of the purulent material, N. Asteroides was identified. An amoxicillin-based treatment was started and continued for three months, with the complete resolution of infection This case is reported for its rarity in our casuistry, and for its difficult differential diagnosis with other potentially serious infections.

Cholecystectomy of an Intrahepatic Gallbladder in an Ectopic Pelvic Liver: A Case Report and Review of the Literature

Directory of Open Access Journals (Sweden)

Rachel Mathis

2017-01-01

Full Text Available Introduction. Ectopic pelvic liver is an exceedingly rare condition usually resulting after repair of congenital abdominal wall defects. Intrahepatic gallbladder is another rare condition predisposing patients to cholelithiasis and its sequelae. We describe a cholecystectomy in a patient with an intrahepatic gallbladder in a pelvic ectopic liver. Presentation of Case. A 33-year-old woman with a history of omphalocele repair as an infant presented with signs and symptoms of symptomatic cholelithiasis and chronic cholecystitis, however, in an unusual location. After extensive workup and symptomatic treatment, cholecystectomy was recommended and performed via laparotomy and hepatotomy using microwave technology for parenchymal hepatic transection. Discussion. Given the rare combination of an intrahepatic gallbladder and an ectopic pelvic liver, advanced surgical techniques must be employed for cholecystectomies, in addition to involvement of hepatobiliary experienced surgeons due to the distortion of the biliary and hepatic vascular anatomy. Conclusion. Cholecystectomy by experienced hepatobiliary surgeons is a safe and effective treatment for cholecystitis in patients with intrahepatic gallbladders in ectopic pelvic livers.

Clinical usefulness of dynamic determination of serum progesterone and HCG levels in patients with threatened abortion, inevitable abortion and ectopic pregnancy

International Nuclear Information System (INIS)

Tu Fengjuan; Ding Jiefeng; Liu Qi

2008-01-01

Objective: To study the clinical differential diagnostic usefulness of dynamic determinations of serum progesterone and HCG levels in patients with abortion and ectopic pregnancy. Methods: Serum progesterone (with CLIA) and HCG (with RIA) levels were determined twice (48h apart) in 98 patients with threatened abortion, 75 patients with inevitable abortion, 52 patients with ectopic pregnancy, and 83 controls. Results: Among the three groups of patients, the serum progesterone levels were highest in the patients with threatened abortion, being significantly higher than those in the other two groups (P<0.05, P<0.01). The progesterone levels were lowest in the patients with ectopic pregnancy, being significantly less than those in other two groups (P<0.05, P<0.01). The serum HCG levels were also significantly higher in the patients with threatened abortion than those in the other two groups (P < 0.05 ), but there were no significant differences between the levels in patients with inevitable abortion and patients with ectopic pregnancy. The differences between the first and second determination HCG levels, either increased or decreased, in patients with ectopic pregnancy were significantly less than those in patients with inevitable abortion (P<0.05). Conclusion: Dynamic determination of serum progesterone and HCG levels might be of differential diagnostic help in patients with threatened abortion, inevitable abortion and ectopic pregnancy.

2008-01-01

Objective: To probe a simple, safe, and minimally invasive method to treat ectopic pregnancy with preservation of the organs. Methods: Superselective catheterization of uterine artery through cannulation of right femoral artery was achieved in 56 patients with ectopic pregnancy. Location of the lesions involved, feeding arteries, and active bleeding were observed on angiography. 150 mg of methylamine neopterin diluted in 100 ml of saline water was infused slowly into the target artery. Small gelatin spongy particles with size of 0.5 mm in diameter were used to embolize the uterine artery until its branches were totally obliterated. Follow-up was undertaken to observe the results of the treatment. Results: Superselective uterine arterial infusion and embolization were successfully performed in all 56 patients without any related complications. Active bleeding in the peritoneum in 33 eases ceased soon after embolization. The embryos in 13 patients were confirmed to have died by ultrasound two days after the procedure. Beta-HCG value dropped to below 5 U/L within two to twelve days. Hemorrhage in the peritoneum dissolved after seven days in all cases. Mixed mass disappeared after one month. Histerosalpingography was performed three months after the procedure in 19 patients and patent fallopians were demonstrated in 11 patients. Conclusions: Superselective uterine arterial infusion and embolization is a minimally invasive procedure, which can be used to effectively treat ectopic pregnancy by disabling the ectopic embryo and embolizing leaking arteries with the advantages of preserving the fallopian tubes.

To present a case of a vital ectopic pregnancy after 8 weeks that was located in the right ovary. Case study and literature review. Hospital outpatient clinic. A 29-year-old primigravida presented with lower abdominal pain and mild vaginal bleeding at 8 weeks after her last menstrual period. Wedge resection of the ovary which did not affect subsequent fertility. Conservative treatment options and preservation of patient's reproductive capacity. The embryo was laparoscopically removed in toto and visualized. Therefore, macroscopic correlation to Carnegie stage 16 of development was possible. Approximately 3% of all ectopic pregnancies are located in the ovaries. Preoperative diagnosis of this extremely rare condition is challenging, because the ectopic tumor often resembles cysts of the corpus luteum. At surgery, the trophoblast tissue or the embryo can rarely be visualized completely.

Cannonball lung metastases as a presenting feature of ectopic hCG expression

Directory of Open Access Journals (Sweden)

Rong-Hsin Yang

2016-08-01

Full Text Available Cannonball metastases refer to well-defined spherical nodules scattered over both lungs, being a classical presentation of hematogenous tumor spreading. Striking progression of lung metastases without established primary malignancy can raise a diagnostic challenge. We herein report three cases with cannonball metastases at initial presentation. Two patients ended up having a choriocarcinoma but no awareness of the presence of primary tumors, and the third had abrupt lung metastases of endometrial cancer while she was being asymptomatic. Relentless progression was illustrated by clinical and radiographic changes. Ectopic expression of human chorionic gonadotropin (hCG would seemingly go some way responsible for fulminant cancer spreading associated with poor prognosis in our patients. The goal of this presentation is to raise awareness of ectopic hCG expression in patients presenting with similar astonishing scenarios.

Ectopic banking of amputated great toe for delayed thumb reconstruction: case report.

Ectopic banking of amputated parts is a recognized technique for delayed replantation of an amputated part when the amputation stump will not permit immediate replantation. This is conventionally performed with the intent of transferring the injured part back to its anatomic position when the amputation stump is more appropriate for replantation. Current warfare conditions have led to a commonly encountered military trauma injury pattern of multiple extremity amputations with protected trunk and core structures. This pattern poses many challenges, including the limit or absence of donor sites for immediate or delayed flap reconstructive procedures. We describe a case in which we ectopically banked the great toe of an amputated lower extremity for delayed thumb reconstruction. Copyright © 2014 American Society for Surgery of the Hand.

Maor, Moshe H.; North, Luceil B.; Cabanillas, Fernando F.; Ames, Angie L.; Hess, Mark A.; Cox, James D.

1998-01-01

Purpose: To review the long-term clinical effects of unilateral kidney irradiation on overall renal function and blood pressure in patients with gastric lymphoma. Methods and Materials: In the study were 27 patients with Stage I or II gastric lymphoma who had undergone irradiation of at least 24 Gy to ≥1/3 of the left kidney. They include 16 women and 11 men, aged 31 to 77, with a mean age of 57.6 years (median 56). Fifteen patients had Stage I and 12 had Stage II disease. In 13 patients the whole kidney had been irradiated, and 14 had had partial kidney irradiation, at doses ranging between 24 and 40.5 Gy. All patients received combined chemotherapy with various drugs: all patients received corticosteroids, and five received cis-platinum. Their follow-up ranged between 0.7 and 7.8 years (mean 3.4 years). Data on possible effects of the treatment on blood pressure, renal function as assessed by blood urea and creatinine, and kidney shrinkage as seen by serial computed tomography scanning were collected on all patients. Results: Three patients had persistent, mild elevations of urea and creatinine levels, which did not require special treatment. All three also received cis-platinum. Ipsilateral kidney shrinkage was evident in most patients. In 19 patients the craniocaudal measurement of the kidney shrank by ≥1.6 cm. Shrinkage in other dimensions was also evident. The degree of atrophy was related to the volume of kidney irradiated. Only two patients developed hypertension, both at a low level of 150/90; one patient had had 40 Gy to the whole kidney, the other 40 Gy to half the kidney. Neither patient had elevated urea or creatinine. Conclusions: Notwithstanding the shrinkage to the irradiated part of the kidney, the treatment did not lead to clinically significant hypertension or renal dysfunction. The administration of cis-platinum to patients with gastric lymphoma that requires kidney irradiation should be further evaluated

Full Text Available Objective. To evaluate serum chlamydia antibody titers (CATs in tubal occlusion or previous ectopic pregnancy and the associated risk factors. Methods. The study population consisted of 55 women wih tubal damage and 55 parous women. CAT was measured using the whole-cell inclusion immunofluorescence test and cervical chlamydial DNA detected by PCR. Odds ratios were calculated to assess variables associated with C. trachomatis infection. Results. The prevalence of chlamydial antibodies and antibody titers in women with tubal occlusion or previous ectopic pregnancy was significantly higher (P<.01 than in parous women. Stepwise logistic regression analysis showed that chlamydia IgG antibodies were associated with tubal damage and with a larger number of lifetime sexual partners. Conclusions. Chlamydia antibody titers were associated with tubal occlusion, prior ectopic pregnancy, and with sexual behavior, suggesting that a chlamydia infection was the major contributor to the tubal damage in these women.

The aim of the study was to compare the accuracy of technetium-99m sestamibi imaging for localization of ectopic parathyroid glands in patients with hyperparathyroidism with that of magnetic resonance (MR) and computed tomographic (CT) imaging. Eleven patients with primary (n=3) or secondary (n=8) hyperparathyroidism were studied with 99m Tc sestamibi parathyroid imaging CT and MR imaging. Images of the neck were acquired at 10 min and 2-3 after tracer injection. The three patients with primary hyperparathyroidism and five patients with secondary hyperparathyroidism underwent parathyroidectomy. The ectopic glands were confirmed by histopathological examination of the resected specimens. In respect of 20 parathyroid glands in the eight patients explored surgically, the sensitivity and specificity of sestamibi imaging were 70% (14/20) and 88%, respectively, those of CT, 40% (8/20) and 88%, and those of MR imaging, 60% (12/20) and 88%. Of these patients, three had parathyroid adenomas while five had hyperplasia (17 glands). Sestamibi imaging localized eight ectopic parathyroid glands, which were surgically confirmed (six were located in the thymus and two in the mediastinum). In one patient explored surgically, the ectopic gland was located outside the field of the MR coil. Although the remaining three cases of secondary hyperparathyroidism were not confirmed surgically, these patients demonstrated sestamibi uptake in five parathyroid glands, including three ectopic glands. MR imagedemonstrated abnormal parathyroid glands in the same regions as sestamibi imaging. Our data indicate that 99m Tc-sestamibi imaging should be used initially to localize the ectopic parathyroid glands in patients with hyperparathyroidism for anatomical guidance prior to MR or CT imaging

Orofacial inflammatory pain is likely to accompany referred pain in uninflamed orofacial structures. The ectopic pain precludes precise diagnosis and makes treatment problematic, because the underlying mechanism is not well understood. Using the established ectopic orofacial pain model induced by complete Freund's adjuvant (CFA) injection into trapezius muscle, we analyzed the possible role of p38 phosphorylation in activated microglia in ectopic orofacial pain. Mechanical allodynia in the lateral facial skin was induced following trapezius muscle inflammation, which accompanied microglial activation with p38 phosphorylation and hyperexcitability of wide dynamic range (WDR) neurons in the trigeminal spinal subnucleus caudalis (Vc). Intra-cisterna successive administration of a p38 mitogen-activated protein kinase selective inhibitor, SB203580, suppressed microglial activation and its phosphorylation of p38. Moreover, SB203580 administration completely suppressed mechanical allodynia in the lateral facial skin and enhanced WDR neuronal excitability in Vc. Microglial interleukin-1β over-expression in Vc was induced by trapezius muscle inflammation, which was significantly suppressed by SB203580 administration. These findings indicate that microglia, activated via p38 phosphorylation, play a pivotal role in WDR neuronal hyperexcitability, which accounts for the mechanical hypersensitivity in the lateral facial skin associated with trapezius muscle inflammation.

We herein report a case of laparoscopic high anterior resection with D3 lymph node dissection for rectosigmoid colon cancer with a horseshoe kidney. A 65-year-old Japanese man referred to our hospital for rectosigmoid colon cancer was found to have a horseshoe kidney on a CT scan. On 3-D CT angiography, an aberrant renal artery was visualized feeding the renal isthmus that arises from the aorta just below the root of the inferior mesenteric artery (IMA). Laparoscopic anterior rectal resection with D3 lymph node dissection was performed. During the operation, the IMA, left ureter, left gonadal vessels and hypogastric nerve plexus could be seen passing over the horseshoe kidney isthmus. With the aid of preoperative 3-D CT angiography, the root of the IMA was identified on the temporal side of the isthmus and divided safely just above the hypogastric nerve. As a horseshoe kidney is often accompanied by aberrant renal arteries and/or abnormal running of the ureter, 3-D CT angiography is useful for determining the location of these structures and avoiding intraoperative injury. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

To study the effect of local interventional treatment of unruptured ectopic pregnancies with multiple-drug injection guided by color Doppler sonography. In this retrospective analysis, 49 patients with an unruptured ectopic pregnancy were treated with two different local injection methods administered under sonographic guidance. The patients were divided into single-drug (n = 23) and multiple-drug (n = 26) injection groups, and they received a locally administered injection of methotrexate alone or a combination including methotrexate, hemocoagulase, antibiotics, and anti-inflammatory drugs, respectively. Overall, local injection treatment was successful in 44 patients. The 5 patients with failed treatment underwent laparotomy about 1 week after single-drug injection. Serum β-human chorionic gonadotropin (β-hCG ) levels, ectopic pregnancy mass sizes, blood flow at various points after treatment, the incidence of pelvic bleeding, and the time for serum β-hCG levels to return to normal and the mass to resolve were analyzed in the remaining 44 patients. Single-drug treatment was successful in 18 patients; 10 of 23 had low to moderate pelvic bleeding after treatment, and 5 were referred for surgery. All 26 patients were successfully treated by multiple-drug injection. Only 2 patients had a small amount of pelvic bleeding. Differences between groups were statistically significant (P injection under color Doppler guidance is a new, safe, and effective method for treating unruptured ectopic pregnancies. It accelerates the serum β-hCG decline and facilitates mass resolution. This regimen is associated with a very low rate of pelvic bleeding, improves the success rate of conservative treatment, and, therefore, has value as an important clinical application.

The administration of intravenous fluid remains the cornerstone treatment for the prevention of contrast-induced acute kidney injury. However, no well-defined protocols exist to guide fluid administration in this treatment. We aimed to establish the efficacy of a new fluid protocol to prevent contrast-induced acute kidney injury. In this randomised, parallel-group, comparator-controlled, single-blind phase 3 trial, we assessed the efficacy of a new fluid protocol based on the left ventricular end-diastolic pressure for the prevention of contrast-induced acute kidney injury in patients undergoing cardiac catheterisation. The primary outcome was the occurrence of contrast-induced acute kidney injury, which was defined as a greater than 25% or greater than 0·5 mg/dL increase in serum creatinine concentration. Between Oct 10, 2010, and July 17, 2012, 396 patients aged 18 years or older undergoing cardiac catheterisation with an estimated glomerular filtration rate of 60 mL/min per 1·73 m(2) or less and one or more of several risk factors (diabetes mellitus, history of congestive heart failure, hypertension, or age older than 75 years) were randomly allocated in a 1:1 ratio to left ventricular end-diastolic pressure-guided volume expansion (n=196) or the control group (n=200) who received a standard fluid administration protocol. Four computer-generated concealed randomisation schedules, each with permuted block sizes of 4, were used for randomisation, and participants were allocated to the next sequential randomisation number by sealed opaque envelopes. Patients and laboratory personnel were masked to treatment assignment, but the physicians who did the procedures were not masked. Both groups received intravenous 0·9% sodium chloride at 3 mL/kg for 1 h before cardiac catheterisation. Analyses were by intention to treat. Adverse events were assessed at 30 days and 6 months and all such events were classified by staff who were masked to treatment assignment. This

Right-Sided Intrarenal Splenosis Mimicking a Renal Carcinoma

Full Text Available We describe a patient who underwent nephrectomy for an enhancing right renal mass that was subsequently pathologically confirmed as right renal splenosis. Since renal splenosis is quite rare and has previously been reported only in the left kidney, we did not consider splenosis in our differential diagnosis during the evaluation of the renal mass. Magnetic resonance imaging, as well as radionucleotide scan using 99mTc-labelled red blood cells, has been utilized for identifying ectopic splenic tissue. An elevated index of suspicion must be present in patients with a history of splenectomy or traumatic splenic rupture to avoid undue nephrectomy.

Hilar ectopic dentate granule cells (DGCs) are a salient feature of aberrant plasticity in human temporal lobe epilepsy (TLE) and most rodent models of the disease. Recent evidence from rodent TLE models suggests that hilar ectopic DGCs contribute to hyperexcitability within the epileptic hippocampal network. Here we investigate the intrinsic excitability of DGCs from humans with TLE and the rat pilocarpine TLE model with the objective of comparing the neurophysiology of hilar ectopic DGCs to their normotopic counterparts in the granule cell layer (GCL). We recorded from 36 GCL and 7 hilar DGCs from human TLE tissue. Compared with GCL DGCs, hilar DGCs in patient tissue exhibited lower action potential (AP) firing rates, more depolarized AP threshold, and differed in single AP waveform, consistent with an overall decrease in excitability. To evaluate the intrinsic neurophysiology of hilar ectopic DGCs, we made recordings from retrovirus-birthdated, adult-born DGCs 2-4 mo after pilocarpine-induced status epilepticus or sham treatment in rats. Hilar DGCs from epileptic rats exhibited higher AP firing rates than normotopic DGCs from epileptic or control animals. They also displayed more depolarized resting membrane potential and wider AP waveforms, indicating an overall increase in excitability. The contrasting findings between disease and disease model may reflect differences between the late-stage disease tissue available from human surgical specimens and the earlier disease stage examined in the rat TLE model. These data represent the first neurophysiological characterization of ectopic DGCs from human hippocampus and prospectively birthdated ectopic DGCs in a rodent TLE model.

Teeth that do not spontaneously erupt in the dental arch or are ectopic must normally be surgically exposed. For orthodontic correction a traction device must be attached to the affected tooth over which the already-raised mucoperiosteal flap is lowered to improve the periodontal condition. The author has developed a system at his private orthodontic practice for this purpose, and it has proven itself over a 10-year period. A traction spring is fastened to a lingual button that is attached to the etched tooth surface using an adhesive. The appliance is activated by systematically shortening the spring. A total of 103 patients were treated successfully in this way, 45 of whom had presented a unilaterally ectopic canine requiring an average treatment time of 17.8 months from surgical exposure to removal of the fixed appliance. None of the patients suffered inflammatory reactions in the oral mucosa adjacent to the traction spring during the treatment. Two impacted teeth were ankylosed and could not be aligned. The EWC-System is clinically a reliable, efficient, easy to use and economical system for the alignment of impacted and ectopic teeth.

The objectives of this study were to calculate the frequency of ectopic pregnancy in the department, define its epidemiological, diagnostic, therapeutic, and prognostic aspects, and determine a clear therapeutic approach appropriate to our setting. In this prospective study, we compiled all cases of ectopic pregnancy seen in 2011 and 2012 in the obstetrics-gynecology department at Ignace Deen University Hospital in Conakry. Ectopic pregnancies represented 1.3% of all deliveries over this period. In the 111 cases in this population, women aged 30-34 years accounted for 31.5%, those pregnant for the first time 40.5%, nulliparous women 35.1%, married women 72.1%, those without schooling 43.2%), and those with a history of sexually transmitted infection 57.6% (these categories are not exclusive, and the same women may be included in several). Secondary amenorrhea with abdominopelvic pain and metrorrhagia was the reason for admission in 56.5% of cases. Ultrasound in early pregnancy is infrequent in Conakry. Almost all of our patients underwent emergency surgery (80.2%) More than half of the ectopic pregnancies were located in the ampulla of the uterine tubes (73.0%). There were three abdominal pregnancies and 2 ovarian. In all cases the treatment was surgical, most often salpingectomy. Postoperative complications occurred in 35.1% of cases, most often anemia (27.9% of all cases) requiring blood transfusion in 11.7% of all cases before, during, or after surgery. The maternal death rate was 1.8%. Ectopic pregnancy remains a major concern at Ignace Deen CHU. Reduction of its frequency requires increased population awareness of sexually transmitted infections and illegal abortions. Management should be prompt and appropriate.

Ischemic reperfusion injuries (IRIs) occur after blood returns to a tissue or organ after a period without oxygen or nutrients, which causes an inflammatory response leading to heterogeneous scarring of the nearby tissue and vasculature. This is associated with long-term decreases blood flow, and necrosis. Although most commonly associated with heart attacks and strokes, IRIs are also a side effect of organ transplants, when the organ is reperfused in the recipient's body after being transported from the donor to the transplant hospital. Currently, the optimal method of monitoring for IRI is limited to biopsies, which are invasive and poorly monitor the spatial heterogeneity of the damage. To non-invasively identify changes in kidneys, the left renal artery in mice (n=3) was clamped for 45 minutes to create an IRI event. Both kidneys of each animal were monitored using photoacoustics (PA) with the VevoLAZR system (Fujifilm-VisualSonics, Toronto) three, four and eight weeks after surgery. IRI-treated kidneys show increased picosirius red staining, indicative of collagen (0.601 vs 0.042, p < 0.0001), decreased size as assessed by cross-sectional area (7.8 mm2 vs 35.9 mm2 , p < 0.0001), and decreased oxygen saturation (sO2; 62% vs 77%, p = 0.02). Analysis of the photoacoustic data shows that a two-point metric, the 715:930 nm ratio of the whole kidney (1.05 vs 0.57, p = 0.049) and the optical spectral slope (OSS) (0.8 * 10-3 vs 3.0 * 10-3, p = 0.013) are both able to differentiate between IRI-treated and healthy kidneys. These data suggest that photoacoustics can be used as a non-invasive method to observe in vivo changes in the kidney due to IRI.
