Abstract Postoperative gastrointestinal bowel transit right after colorectal resection has not yet been clarified. Thirty patients with rectosigmoid cancer were treated in this pilot study. The nasogastric tube was removed on the first postoperative day. One Sitzmarks capsule was given to each patient on the second postoperative day. Abdominal X-rays were taken at 3, 6, 8, 24, 48, and 72 hours after capsule intake. Distribution of the remaining Sitzmarks capsules were counted on X-ray films to clarify postoperative gastrointestinal movement after bowel resection. All Sitzmarks capsules were observed in the stomach at 3 and 6 hours after capsule intake. At 8 hours (second postoperative day), the Sitzmarks capsules were distributed from the stomach to the small intestine. Sitzmarks capsules were distributed in the right side colon at 24 hours (third postoperative day) after intake. Although the main distribution was still in the right side colon, several patients had evacuations accompanied by the disappearance of the Sitzmarks capsules. In 50% of the patients, it took approximately 72 hours (fifth postoperative day) for the first defecation after intake of the capsules. However, the Sitzmarks capsules remained mainly in the right side colon. Eight hours after intake, the majority of the Sitzmarks capsules shifted to the small intestine. Therefore, medication or feeding should be safely possible starting on the second postoperative day. There was no particular impact of bowel resection on upper gastrointestinal transit in patients with rectosigmoid cancer.

We present two patients with air found in the right upper quadrant on standard abdominal x-ray. One was diagnosed with pneumobilia and underwent elective surgery for a bilioenteric fistula. The other was diagnosed with portal vein gas and underwent an emergency exploratory laparotomy at which a superior mesenteric artery embolism was found. The differential diagnostic criteria for pneumobilia and portal vein gas are described. If portal venous gas is found on x-ray in patients with abdominal pain, it is recommended that management is aggressive, meaning an emergency exploratory laparotomy, because mortality in such cases is approximately 75%.

A Hoffa fracture is a type of supracondylar distal femoral fracture with fracture line located in the coronal plane. It is a rare injury consisting of tangential (coronal shear) fracture of distal femoral condyles. Unicondylar knee fractures are rare and present some diagnostic difficulties due to poor visibility on standard X-ray and are especially harder to identify in non-displaced fracture. A fifty-four-year-old male presented to our emergency room with a chief complaint of pain over his right knee that started 10 months prior. He previously was involved in a motor vehicle accident and underwent open reduction and internal fixation with plate and screws. Physical examination revealed swelling and tenderness over the right knee with limited range of motion. Plain X-ray showed union of tibia plateau fracture with plate and screws and no evidence of distal femoral fracture. A magnetic resonance imaging of the right knee was performed and revealed an intraarticular lateral condyle femur fracture with transverse configuration that was previously missed on plain X-ray. Arthroscopy-assisted reduction and internal fixation using antero-posterior and postero-anterior oriented screws were performed and good reduction was achieved. Diagnosis of this type of fracture is challenging and require some experience. Awareness of such entity and strong clinical suspicion are essential for diagnosis because most of the time the standard X-rays may appear normal. Arthroscopy-assisted fracture fixation using antero-posterior and postero-anterior oriented screws for Hoffa fracture offers many advantages and allows for early mobilization postoperatively without any loss of reduction.

<p>GyneFix® is a small, frameless, armless, flexible intrauterine device. The proximal end contains a knot that is anchored in the uterine fundus using a special apparatus. A 31-year-old woman presented with abdominal cramps ten days after GyneFix® insertion. Transvaginal ultrasonography was unsuccessful in locating the intrauterine device therefore a direct X-ray sonogram of the abdomen while standing was performed. The X-ray sonogram of the abdomen showed the intrauterine device in the right quadrant. An exploratory laparoscopy was performed and showed that the intrauterine device perforated the uterine fundus and was embedded in the mesentery of the ileum. The intrauterine device was removed without complication. Although the reported complication rates are very low for GyneFix®, practitioners should be well trained and should be aware of such complications that could lead to bowel resection. We report the first case of a GyneFix®- Intrauterine device presenting with uterine perforation and nearly intestinal perforation since its recent introduction into the Turkish market.<br /><br /></p>

Standard radiography in direct projection is the “gold standard” in the diagnosis of hand osteoarthritis (HOA). However, the currently clinically most severe “erosive” or “inflammatory” phenotype of HOA is characterized by the presence of inflammatory symptoms such as bone marrow lession (BML), synovitis and tenosinovitis, which are not visible on the radiograph by the nature of the study due to the low optical density. In addition, X-ray examination is planar and has no possibility of multiplanar visualization. This dictated the need to search for a more informative visualization technique in HOA.Aim – to compare the sensitivity and specificity of standard radiography and magnetic resonance imaging (MRI) techniques in determining the symptoms of osteoarthritis (OA) of the distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the right hand; to determine the indications for the appointment of MRI in patients with HOA.Materials and methods. The study included 64 women with clinically verified diagnosis of HOA according to ask criteria. For the first time, X-rays of the joints of the right hand in the anterior-posterior projection and MRI were performed for each of them. Each patient completed the AUSCAN questionnaire. X-rays were described according to the Kellgren and Lawrence systems, magnetic resonance imaging was analyzed according to the modified OHOA system. The sensitivity and specificity of the methods were compared based on the detection of 4 symptoms detected by radiography and MRI: joint space narrowing (JSN), osteophytes (OP), erosions and subluxations. The average age of the patients was 65.28±6.82 years, the age of onset was 48.81±7.73 years, the duration of the disease was 15.0 (10.0–19.5) years.Results. Both methods showed approximately equal identification JSN symptom in DIP and PIP, 95% definition JSN in MCP. OP were detected in 88% of patients in DIP according to radiography and in 95% – using MRI (p>0.05). In PIP OP were observed in 70% of patients on radiographs and in 86% on magnetic resonance imaging, in MCP – in 45% and 66% of cases, respectively. Erosion in DIP were found in 41% of patients according to MRI and 34% as a result of X-ray examination, in PIP – in 27% and 13% of cases, in MCP – in 60% and 8% of cases, respectively. Subluxations were determined in DIP 23% on radiographs in 31% of cases by MRI, in PIP – in 8% and 6% (p>0.05), in MCP subluxations almost never met – in 3% of cases by conventional radiography.Conclusions. MRI in HOA can be used in the detection of erosive process, differential diagnosis with other diseases of the joints, determination of inflammatory changes in the hands and assessment of their severity, but has no significant advantages over standard radiography in determining the symptoms of degenerative-dystrophic nature (JSN and OP). Subluxations of the MCP joints are not typical for the HOA.

Pneumonia is a life-threatening disease, which occurs in the lungs caused by either bacterial or viral infection. It can be life-endangering if not acted upon at the right time and thus the early diagnosis of pneumonia is vital. The paper aims to automatically detect bacterial and viral pneumonia using digital x-ray images. It provides a detailed report on advances in accurate detection of pneumonia and then presents the methodology adopted by the authors. Four different pre-trained deep Convolutional Neural Network (CNN): AlexNet, ResNet18, DenseNet201, and SqueezeNet were used for transfer learning. A total of 5247 chest X-ray images consisting of bacterial, viral, and normal chest x-rays images were preprocessed and trained for the transfer learning-based classification task. In this study, the authors have reported three schemes of classifications: normal vs. pneumonia, bacterial vs. viral pneumonia, and normal, bacterial, and viral pneumonia. The classification accuracy of normal and pneumonia images, bacterial and viral pneumonia images, and normal, bacterial, and viral pneumonia were 98%, 95%, and 93.3%, respectively. This is the highest accuracy, in any scheme, of the accuracies reported in the literature. Therefore, the proposed study can be useful in more quickly diagnosing pneumonia by the radiologist and can help in the fast airport screening of pneumonia patients.

Abstract Background Osteopetrosis is a rare inherited bone disorder affected individual by osteoclast disfunction and increasing bone density. Surgery was taken for histological examination of the specimen and evidence of malignancy was not found. Finally, X-ray and gene detection lead to the diagnosis. Case presentation We report a 10-year-old girl with two years history of pus rhinorrhea, nasal obstruction and smelly nose. She was diagnosed and treated as sinusitis. But the symptoms were recurrent. Ten months ago, she was afflicted with persistent swelling and broken skin on the right cheek. All the laboratory findings showed normal. During surgery, we resected the right gingiva, the right nasal mucosa and the right facial tissue for biopsies. Histological examination showed proliferation of granulation tissue in chronic inflammatory mucosa. X-rays showed generalized sclerosis. Genetic analysis strongly supported a novel mutation of TNFRSF11A gene which caused osteoporosis. We found a novel mutation of the c.1196C > G (p.S399X) in exon 9 of TNFRSF11A. The TNFRSF11A gene encodes RANK, which is fundamental for osteoclast formation. Conclusion Osteopetrosis is a rare genetic bone disease characterized by increased bone density because of bone resorption failure. Diagnosis is based on X-ray and gene analyze. Osteoclasts are bone-related cells derived from hematopoietic cell lines. Since osteoclasts arise from a hematopoietic progenitor cell of the monocytic lineage, the defect can be corrected by hematopoietic stem cell transplantation (HSCT). Better understanding of this pathological situation and pathogenesis is so important to plan appropriate immunotherapy to benefit.

A single large dose of x-rays over the abdomen will cause a definite injury of the mucosa of the small intestine and the severity of the clinical intoxication seems to parallel this recognizable epithelial injury. This clinical intoxication lasts 4 to 6 days if the x-ray dose is sublethal. Subsequent doses of radiation given within this period of clinical intoxication give recognizable evidence of summation or a cumulative effect. Small but repeated doses of radiation given within a 5 or 6 day period will cause practically the same cell injury and clinical intoxication as will a single dose representing the sum of the small doses expressed in milliampere minutes. Doses of radiation given at 6 day or longer intervals show no evidence of summation. The reaction of this relatively sensitive intestinal epithelium to radiation may be similar to the reaction of certain deep lying tumor tissues to x-ray therapy and our experiments may give information of value to physicians concerned with x-ray or radium therapy.

Abstract Background Munchmeyer's disease (MM) or Fibrodysplasia ossificans progressivais an extremely rare genetic disorder characterized by heterotopic ossification of muscle and connective tissue during flare-ups, which can lead to the creation of a true second skeleton. we report an original observation with diagnostic difficulty. Observation We report the case of 37-year-old women who consulted for cervical stiffness with painful hypertrophy of the left sternocleidomastoid muscle, dorsal scoliosis, tendon retractions in limbs with a semi-flexion attitude. In addition, she presented a deformity of the forefoot with hallux valgus and a triangular shape. X-ray of the right arm showed ossification of the biceps brachii and that of the foot showed interphalangeal ankyloses with agenesis of a phalanx of the big toe. X-rays of the cervical spine revealed posterior arch ankyloses with fusion of some vertebrae. Despite the late onset of symptoms, the diagnosis of MM was suggested and confirmed by a genetic study which revealed a heterozygous c.617G&gt; A [p. Arg206His] mutation, located in exon 6 of the gene. Conclusion MM is an extremely rare but disabling condition. It should be considered in unexplained muscle enlargement occurring at any age particularly if associated with congenital malformations of the Hallux. The discovery of the ACVR1 gene mutation offers hope for the development of therapies for this hitherto incurable disease.

Absolute Structure

We propose a new method to determine the absolute structure of chiral crystals, which is based on the chiral asymmetry of multiple scattering diffraction. It manifests as a difference in the azimuthal dependence of the forbidden Bragg reflection intensity measured with left and right circularly polarized X-ray beams. Contrary to the existing ones, the suggested method does not use X-ray anomalous dispersion. The difference between the Renninger scans with circularly polarized X-rays has been experimentally demonstrated for the 001 reflection intensities in the right- and left-handed quartz single crystals. A Jmulti-based code on model-independent three-wave-diffraction approach has been developed for quantitative description of our experimental results. The proposed method can be applied to various structures including opaque, organic and monoatomic crystals, even with only light elements. To determine the type of isomer, the Renninger plot of a single forbidden reflection is sufficient.
