Pancreatic Duct Stones

A 62 years-old Caucasian male, who had a consumptive condition associated with recurrent episodes of abdominal pain, was evaluated in a Gastroenterology consultation. Physical examination was quite innocent and the following imaging exams were performed. A Computed Tomography (CT) showed a thin gallbladder and chronic pancreatitis signs with pancreatic intraductal stones, dominant at tail and body, associated with pancreatic tail atrophy. An abdominal-Magnetic Resonance Imaging (MRI) showed an abnormal pancreatic parenchyma, a mild Wirsung dilatation and an unknown pancreatic head stenosis etiology. Therefore, to clarify the pancreatic stenosis, an echo-endoscopy (EUS) was performed. This exam showed a 10-mmstone associated with a focal narrowing in the head/tail transition. A pancreatoscopy-guided holmium laser using a mini-endoscope inserted into the pancreatic duct successfully broke the impacted stone and cleared the obstruction, without complications. After that, endotherapy with plastic stents was repeatedly done, during the following 6 months. After endoscopic treatment, the patient recovered quite well, without any symptoms, without pancreatic stenosis and higher quality of life.

Endometriosis is a gynecological pathology with chronic symptoms, which negatively affects the patient’s quality of life. The prevalence of endometriosis in asymptomatic women is between 2% and 50%, depending on the populations studied and the method of diagnosis. The severity of the symptoms as well as the probability of diagnosing endometriosis increases with age9. Because endometriosis is a gynecological condition with a nonspecific clinical picture, sometimes even asymptomatic, imaging technology can be considered the first line of diagnosis for this pathology. The main objective of this study is to evaluate the sensitivity and specificity of nuclear magnetic resonance imaging (MRI) used in the diagnosis of endometriotic lesions depending on their location, and compare the results obtained with the intraoperative appearance considered a reference standard in the diagnosis of endometriosis. Our study revealed the highest specificity for MRI in the case of endometriotic bladder invasion, respectively the highest sensitivity for endometriotic rectal nodules.

Purpose To assess strength, size, and muscle quality differences between younger and older males and females in response to training. Methods The bicep and tricep of the non-dominant arm were trained for twelve weeks in younger and older males and females (n = 41). The bicep of both arms were assessed pre and post for muscle strength using one-repetition maximum (1 RM) testing, and size using magnetic resonance imaging (MRI). Results Strength (p < 0.05), mCSA (p < 0.05), and 1 RM MQ (p < 0.00) increased in response to training in all subjects regardless of age or gender. Younger and older subjects had similar increases in strength (45.49 ± 15.30% vs. 42.67 ± 26.67% respectively), mCSA (16.22 ± 7.98% vs. 19.17 ± 6.19% respectively), and 1RM MQ (25.73 ± 15.76 vs. 19.67 ± 20.66 respectively). Women increased their strength (55.59 ± 19.45% vs. 32.87 ± 15.66% p < 0.00 respectively), size (20.36 ± 6.29% vs. 14.72 ± 7.28% p < 0.02 respectively), and 1 RM MQ (29.74 ± 18.33% vs. 16.30 ± 15.59% p <.02) more than men. In comparing age and gender, younger females increased their strength more than older males (56.42 ± 12.92% vs. 29.17 ± 21.8% p <.02 respectively). Older females also increased their strength more than older males (54.68 ± 25.73 vs. 29.17 ± 21.80% respectively). Younger females increased their 1 RM MQ more than older males (.18 ± .08 kg/cm vs. .06 ± .08 kg/cm p <.02 respectively). Conclusion Strength and mCSA increases similarly in older and younger subjects. However, the overall strength and quality of the muscle seems to improve more in women than in men.

Pelvic floor disorders such as Pelvic Organ Prolapse (POP) negatively impact the health and quality of life of millions of women worldwide. POP is characterized by the descent of the pelvic organs into the vagina due to compromised connective tissue support, resulting in discomfort and urinary/fecal incontinence. Magnetic Resonance Imaging (MRI) has been used to aid in the quantification of these anatomical changes, however the inter- and intra-observer repeatability necessary to make reliable conclusions about changes in anatomical positioning is questioned using current methods. The aim of this study was to quantify the degree of variability produced from inter-observer manual tracings of the vagina from MRI scans using a statistical shape matching approach.

Abstract Objective This is the first systematic review and meta-analysis on the overall incidence of intraspinal abnormalities in patients with congenital scoliosis (CS) and potential influencing factors. Methods We searched three large electronic databases (PubMed, EMBASE, and Cochrane Library) for potentially relevant studies. The quality of the included studies was assessed independently by two authors using the Methodological Index for Non-Randomized Studies (MINORS) criteria. Data on the number of CS patients, number of CS patients with intraspinal abnormalities, sex of the patients, and CS types were extracted from the included studies. R software was used to pool and analyze all the extracted data. Results This meta-analysis included 10 articles, and 671 of 1863 CS patients undergoing magnetic resonance imaging (MRI) examinations were identified to have intraspinal abnormalities. The overall incidence of intraspinal abnormalities in the patients with CS was 37% (95% CI, 29–45%). Diastematomyelia was the most common intraspinal abnormality and was detected in 45.60% of the patients with intraspinal abnormalities (306/671). The remaining intraspinal abnormalities included syringomyelia (273/671, 40.69%), tethered cord (190/671, 28.32%), low conus (58/671, 8.64%), intraspinal mass (39/671, 5.81%), Chiari malformation (32/671, 4.77%), fatty filum (27/671, 4.02%), spina bifida (occulta excluded) (17/671, 2.53%), tumor (17/671, 2.53%), cyst (12/671, 1.79%), syringomyelus (4/671, 0.60%), dural ectasia (1/671, 0.15%), and undiagnosed cord MRI hyperintensity (1/671, 0.15%). The patient’s sex and CS type were not factors that affected the incidence of intraspinal abnormalities in CS patients (all P > 0.05). Conclusions This meta-analysis revealed that the overall incidence of intraspinal abnormalities detected by MRI in CS patients was 37%. Diastematomyelia was the most common intraspinal abnormality. The patient’s sex and CS type were not factors that affected the incidence of intraspinal abnormalities in CS patients.

Intended Use

An increasing number of patients with metal implants are being referred for magnetic resonance imaging (MRI) investigations. Implants and devices may be divided into two groups, namely active and passive. This article will focus on passive devices. A device is MR-safe when it is used in the MR environment, but presents no additional risk to the patient or other individuals, although the quality of diagnostic information may be affected. MR procedures may be contraindicated due to various interactions between the MR environment and medical devices, which include torque, translational force, heating, induced electrical currents, magnetic field interactions, artefacts, and misrepresentation. Therefore, before deciding whether any object is MRsafe/ compatible, the intended use and the possible retaining mechanisms must be considered.

Abstract Osteogenesis Imperfecta (OI) is a bone disorder that causes bone to be brittle and easy to fracture. The patient suffered from this disease will have poor quality of life. Simulation on the bone fracture risk would help medical doctors to make decision in their diagnosis. Detection of edges from the OI images is very important as it helps radiologist to segmentize cortical and cancellous bone to make a good 3D bone model for analysis. The purpose of this paper is to review the fundamentals of fuzzy logic in edge detection of OI bone as it is yet to be implemented. Several fuzzy logic concepts are reviewed by previous studies which include fuzziness, membership functions and fuzzy sets regarding digital images. The OI images were produced by modalities such as Magnetic Resonance Imaging (MRI), Ultrasound, or Computed Tomography (CT). In summary, researchers from the reviewed papers concluded that fuzzy logic can be implemented to detect edges in noisy clinical images.

Pancreaticoduodenectomy still is a “gold standard” in treatment of hepatopancreaticobiliary tumors. The causes of pancreatic fistula were analyzed in 414 patients aged from 22 to 81 following pancreaticoduodenectomy due to periampullary tumors. The said patients were operated on during the period from 2008 to 2017. The aim of this study is to improve outcomes of pancreatic resection based on a retrospective analysis of the causes of postoperative pancreatic fistulae and the development of a range of measures to prevent the above complication. Influence of risk factors of pancreatic fistula formation was evaluated by Pirson’s method (χ2). The factors contributing to the occurrence of pancreatic fistulas included type of resection (Whipple pancreaticoduodenectomy, pylorus preserving pancreaticoduodenectomy; χ2=8.616,1, p=0.0033, p<0.01), kind of pathology (cancer of the pancreatic head; χ2=7.658,1, p=0.0057, p<0.01), type of pancreaticojejunostomy (invaginative pancreatic duct-jejunostomy; χ2=17.83,1, p=0.0001, p<0.001) and technique for drainage of the major pancreatic duct (pancreaticojejunostomy on external drainage; χ2=16.40,1, p=0.0001, p<0.001). The detailed study of risk factors for the occurrence of pancreatic fistula is essential for improving the prognosis, prophylaxis and treatment of this pathology. The quality of the surgical intervention and the course of the postoperative period in patients with periampullary tumors depend on the choice of resection type, techniques for surgical interventions on the pancreas.

Abstract Objective: Pregnancy of Rudimentary Horn is a type of ectopic pregnancy, that is recognized almost always during surgical treatment of a rupture of the rudimentary horn. This is an obstetric case diagnosed preoperatively by magnetic resonance imaging (MRI).Case: We report the case of a 19-years-old primigravida patient with rupture of rudimentary horn in 26th gestational week. The patient presented with sudden onset severe abdominal pain in the emergency room. Intraabdominal free fluid is detected. To evaluate the etiology of free fluid and location of the gestational sac, an abdominal magnetic resonance imaging (MRI) scan was planned. The decision of emergent laparotomy is made because of sonographic detection of abdominal excessive -concentrated- free fluid, abdominal tenderness, and 2 points decrease of hemoglobin value in the control hemogram. A rudimentary horn pregnancy and fundal rupture of the rudimentary part of the uterus are diagnosed during the surgical procedure. A baby -live- weighing 450 grams was delivered. The ruptured rudimentary horn and same-sided tuba uterina were surgically removed.Conclusion: Rudimentary horn pregnancy is a rare ectopic pregnancy. Diagnosis is difficult clinically, even with diagnostic imaging modalities. Identifying both cornuas systematically in all patients increases the detection rate. The absence of continuity between the gestational sac’s lumen and the cervical canal on imaging is an important finding. Due to the serious maternal and fetal complications, its detection at an early week may be life-saving.

Abstract Pancreatic duct stones are direct sequelae of chronic pancreatitis (CP) and can occur in ∼50% of patients. Selection of the appropriate treatment method for pancreatic duct stones depends on location, size and number of stones. We present a patient with upper abdominal pain and weight loss for the previous 3 months. Diagnostic workup detected a chronic inflammation of the pancreas with stone in the main pancreatic duct and a nodular lesion in the head of the pancreas. Endoscopic retrograde cholangiopancreatography was performed without success. Given the rise in incidence and prevalence of CP, the potential complications and high mortality rate, it is imperative that physicians understand the risk factors, disease process and management of this disease. Pancreaticoduodenectomy in patients with CP is a feasible option for the treatment of focal cystic lesions to the head of the pancreas associated to pancreatic stone in selected cases.
