Introduction: Acute abdomen might indicate a progressive intra-abdominal condition that is threatening to life or capable of causing severe morbidity. A good history, thorough clinical examination, laboratory investigations and imaging studies is necessary in order to arrive at a correct diagnosis. The aim of our study was to compare the diagnostic yield of traditional three-view abdominal x-ray series (upright chest x-ray, supine and upright abdominal x-rays) with that of ultrasound in patients presenting with non traumatic acute abdominal surgical pain. Methods: This prospective study was conducted between February and July 2010 on 65 consecutive patients. Critically ill patients, pregnant ladies, patient with trauma abdomen, acute abdomen due to gynaecological pathologies were excluded from our study. Detail abdominal ultrasound was done. After ultrasound traditional three-views acute abdominal x-ray series (AAS) were taken. Final diagnosis was made on the basis of operative findings/therapeutic response/ histopathological/ laboratory findings. Finally, accuracy of clinical diagnosis, plain film and ultrasound in evaluation of acute abdomen was determined. Results: Ultrasound yielded an overall sensitivity and specificity of 78.7% and 84.6.6% respectively. The AAS interpretations yielded an overall sensitivity and specificity of 23.4% and 38.40% respectively. Conclusion: Plain x ray is less sensitive in the evaluation of nontraumatic acute abdomen so it should be used together with ultrasound abdomen in order to arrive at a correct diagnosis.

Category: Other Introduction/Purpose: Foot and ankle surgeons routinely prescribe diagnostic imaging that exposes patients to potentially harmful ionizing radiation. The purpose of this study is to characterize patients’ knowledge regarding radiation exposure associated with common forms of foot and ankle imaging. Methods: A survey was administered to all new patients prior to their first foot and ankle clinic appointments. Patients were asked to compare the amount of harmful radiation associated with chest x-rays to that associated with various types of foot and ankle imaging. Results were tabulated and compared to actual values of radiation exposure from the published literature. Results: A total of 890 patients were invited to participate, of whom 791 (88.9%) completed the survey. The majority of patients believed that a foot x-ray, an ankle x-ray, a “low dose” CT scan of the foot and ankle (alluding to cone-beam CT), and a traditional CT scan of the foot and ankle all contain similar amounts of harmful ionizing radiation to a chest x-ray (Table 1). This is in contrast to the published literature, which suggests that foot x-rays, ankle x-rays, cone beam CT scans of the foot and ankle, and traditional CT scans of the foot and ankle expose patients to 0.006, 0.006, 0.127, and 0.833 chest x-rays worth of radiation. Conclusion: The results of the present study suggest that patients greatly over-estimate the amount of harmful ionizing radiation associated with plain film and cone-beam CT scans of the foot and ankle. Interestingly, their estimates of radiation associated with traditional CT scans of the foot and ankle were relatively accurate. Results suggest that patients may benefit from increased counseling by surgeons regarding the relatively low risk of radiation exposure associated with plain film and cone-beam CT imaging of the foot and ankle.

Abstract OBJECTIVE In evaluating the pediatric cervical spine for injury, the use of adult protocols without sufficient sensitivity to pediatric injury patterns may lead to excessive radiation doses. Data on injury location and means of detection can inform pediatric-specific guideline development. METHODS We retrospectively identified pediatric patients with codes from the International Classification of Diseases, 9th Revision, for cervical spine injury treated between 1980 and 2000. Collected data included physical findings, radiographic means of detection, and location of injury. Sensitivity of plain x-rays and diagnostic yield from additional radiographic studies were calculated. RESULTS Of 239 patients, 190 had true injuries and adequate medical records; of these, 187 had adequate radiology records. Patients without radiographic abnormality were excluded. In 34 children younger than 8 years, National Emergency X-Radiography Utilization Study criteria missed two injuries (sensitivity, 94%), with 76% of injuries occurring from occiput–C2. In 158 children older than 8 years, National Emergency X-Radiography Utilization Study criteria identified all injured patients (sensitivity, 100%), with 25% of injuries occurring from occiput–C2. For children younger than 8 years, plain-film sensitivity was 75% and combination plain-film/occiput–C3 computed tomographic scan had a sensitivity of 94%, whereas combination plain-film and flexion-extension views had 81% sensitivity. In patients older than 8 years, the sensitivities were 93%, 97%, and 94%, respectively. CONCLUSION Younger children tend to have more rostral (occiput–C2) injuries compared with older children. The National Emergency X-Radiography Utilization Study protocol may have lower sensitivity in young children than in adults. Limited computed tomography from occiput–C3 may increase diagnostic yield appreciably in young children compared with flexion-extension views. Further prospective studies, especially of young children, are needed to develop reliable pediatric protocols.

AbstractIn our series of 400 Chinese children with foreign body aspiration (FBA),343 cases were evaluated by fluoroscopy and/or plain chest X-rays before endoscopic removal of the foreign bodies. The majority of the foreign bodies (FBs) were organic (378/400, 94.5 per cent). The results showed that mainstem bronchial foreign bodies were diagnosed correctly in 68 per centof cases compared with 65 per cent correct diagnoses with segmental bronchial foreign bodies, but only 22 per cent correct diagnoses with tracheal, and 0 per cent correct diagnosis in those with laryngeal foreign bodies. Eighty per cent (32/40) of the children with laryngotracheal FBs had normal X-ray findings, whereas 67.7 per cent (205/303) of the children with bronchial FBs had abnormal chest X-ray findings. The most common positive radiological signs in the children with tracheobronchial FBs were obstructive emphysema (131/213, 62 per cent) and mediastinal shift (117/213, 55 percent). The incidence of major complications was related not only to the size of the foreign body and its location but also the duration since aspiration. The most common types of bronchial obstructions by airway FBs are discussed.

Introduction. Foreign bodies in the gastrointestinal tract are various objects of organic and inorganic origin, which are swallowed - not as food - either accidentally or intentionally. The article describes a clinical case of a 13-year-old child with multiple foreign bodies in his gastrointestinal tract which could cause serious complications, such as: perforation of hollow organs, peritonitis, intestinal obstruction, internal bleeding. By statistics, every fourth patient of the conscious age with foreign bodies in the gastrointestinal tract can potentially have problems in the neuropsychic sphere.Material and methods. A 13-year-old boy was admitted to the Clinical and Research Institute of Emergency Pediatric Surgery and Trauma (CRIEPST) with nausea, repeated vomiting after each meal and water drinking. The careful anamnesis revealed that before the boy’s state deteriorated, he had swallowed a large number of magnets and metal objects within a short period of time. X-rays examination found multiple foreign bodies in his gastrointestinal tract. They were removed during esophagogastroduodenoscopy (EGDS) and surgical intervention.Results. The plain-film X-ray examination of the abdomen in the projection of the stomach revealed a radiopaque group of foreign bodies of a rounded shape as a conglomerate. At FEGDS, 54 objects were removed: 4 metal balls up to 0.5 cm in diameter, 47 round magnets up to 1.5 cm in diameter, a metal chain and two screws. During laparotomy and gastrotomy 99 foreign bodies were removed: 82 magnet balls 0.5 cm in size, 16 metal balls 1.5 cm in size, 1 bolt. The postoperative period was uneventful. The child was discharged on the 12 th day after surgery in the satisfactory state.Conclusion. Due to timely diagnostics and proper curative tactics, multiple foreign bodies were revealed and removed from the child’s stomach endoscopically and surgically within a short period of time. A correctly chosen curative tactics resulted in a complete recovery of the patient without complications on the 12th hospitalization day.

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.

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.

X-Ray images are the most widely recognized methods for medical imaging accessibility for individuals during the wounds and mishaps. X-rays are most frequent and the oldest form of medical imaging. Yet, the minute fracture identification using the X-Ray image is beyond the realm of imagination,because of the complication of bone organisation and the dissimilarity in visual attributes of fracture upon their location. This is the reason why it it is hard to detect the fractures and furthermore decide the seriousness of the damage. The major challenges of X-Ray imaging are the presence of noise, intensity ambiguity, and overlapping tissues. This creates a hurdle in correct diagnosis and delays treatment. The various rates require the human services experts to analyze countless x-ray images. computerized detection of fractures in X-Ray images can be a huge commitment for helping the doctors in settling on quicker and increasingly precise diagnostic decisions and speeds up the plan for the treatment. This research compares the existing fracture detection techniques.From various fractures, programmed identification is viewed as challenging since they are unique and variable in presentation and their results are quite un predictable.The major challenges for computer-aided fracture detection can be accurate segmentation process, automatic identification of the region of interest (bone fracture), evaluation and suggestive course of action.

Abstract Aim Abdominal radiographs (AXRs) are commonly used in the setting of acute abdominal pain. However, with low diagnostic yield, they can increase workload within the radiology department, increase patient radiation exposure and ultimately delay further diagnostic imaging. The average cost of an abdominal film, excluding staffing costs, is £45. This study aimed to investigate the appropriate use of AXRs in the emergency setting, as per the Royal College of Radiologists Guidelines (RCR). Methods A single centre retrospective review was conducted of all patients referred to the emergency surgical team over a 21 day period. Data was retrieved from electronic handover records. Demographics, radiology request forms and imaging results were obtained from up to date electronic care records. Results A total of 160 patients presented within the audit window, with a median age 49 (16-94) and 61.3% male. Overall, 36.9% of patients underwent an abdominal x-ray, 66.1% of which were not indicated in accordance with RCR guidelines. 71.2% of patients who underwent an abdominal x-ray required further diagnostic imaging by means of CT or USS. Only 10.2% of AXRs provided diagnostic information. Total cost expenditure for inappropriate AXRs = £1,755, excluding staffing costs. Conclusions Approximately two thirds of AXRs performed did not comply with the published RCR guidelines. Adherence to RCR guidelines can reduce needless radiation exposure, hospital costs and delay to diagnosis. We plan to conduct a teaching session on the RCR guidelines alongside the development of information posters, and re-audit our results.

Although laboratory rabbits are commonly used as models of appendicitis in man, spontaneous appendicitis was only described ante-mortem in one pet rabbit with an acute abdomen. The aim of this article is to describe two spontaneous cases of appendicitis in pet rabbits, to describe therapeutic appendectomy, and to discuss the microbial flora of the inflamed appendix. A 5-month-old intact female and a 16-month-old, neutered male were presented to the veterinary clinic with restlessness, anorexia, and reduced faecal output. The main clinical findings were restlessness, severe discomfort on abdominal palpation, a mid-abdominal palpable tubulous mass and an elevated rectal temperature. Blood analyses showed lymphocytosis, monocytosis, and hyperglycaemia. Radiography was inconclusive. Abdominal ultrasound revealed a presence of a tubular structure with wall thicknesses of 4.2 and 3.7 mm in the two rabbits, respectively. The tubular structure had a rounded, closed end, and a multilayered wall, suggestive of appendicitis. Due to metabolic acidosis and poor prognosis, the first rabbit was euthanized. In the 16-month-old rabbit, appendectomy was performed. Recovery was uneventful, and 4 h after surgery, the rabbit started to become normally active. Postoperative care consisted of fluid therapy, multimodal analgesia, supportive care and prokinetics. Follow-up examinations at 10 days, 1 month, and at 11 months after the surgery did not show any abnormal clinical or laboratory findings. Histopathological examination of appendices from both rabbits showed gangrenous appendicitis. Aerobic cultivation showed the presence of pure culture of Klebsiella variicola sensitive to enrofloxacin, marbofloxacin, tetracycline, cefuroxime, trimethoprim sulphonamide, neomycin, and gentamicin. Restlessness associated with anorexia, abdominal pain, palpable abdominal mass, hyperglycaemia, lymphocytosis, and elevated rectal temperature may be indicative of inflammation within the gastrointestinal tract. Abdominal ultrasound is recommended in rabbits with showing these clinical signs because radiography can be inconclusive. Appendicitis is a life-threatening condition, which should be included into the list of differential diagnoses; for the rabbit, an acute abdomen and gastrointestinal stasis syndrome and must be treated immediately. K. variicola may be associated with appendicitis in rabbits as a causative agent or in association with appendix intraluminal dysmicrobia.

Background and aims: Children with sickle cell disease (SCD) frequently present with limb pain. Differentials include vaso-occlusive episode (VOE) and osteomyelitis (OM). X-rays expose to radiation but rarely aid in diagnosis. We audited the use of x-ray in investigating children with SCD presenting with limb pain to a South London hospital and analysed whether x-rays aid in diagnosis. Methods: Patients aged 0-18 with SCD were identified using the hospital’s SCD database. Admissions from January 2010 to September 2019 in which limb pain was a documented symptom were included. Results: Of 342 patients investigated, there were 188 admissions with limb pain. Diagnoses at discharge were: 174 VOE, 4 OM, and 7 others. 44 (25%) of those with VOE had limb x-rays, compared with 3 (75%) of those with OM. Of those x-rayed, 11 with VOE and all with OM had a subsequent MRI. None of the x-rays assisted in confirming the diagnosis or change management. Of the VOE patients, more of those that were x-rayed had swelling (48% vs 8%, p=<0.0001), and fevers (57% vs 37%, p=0.021), and peak CRP was higher (109 vs 75, p=0.044). Conclusions: X-rays were frequently used to investigate children with SCD. Limb swelling, fevers and higher CRP, features potentially suggestive of OM, were more common in those that were x-rayed. X-rays did not aid in distinguishing VOE and OM or change management.
