<span>This paper presents the utilization of an ultrasonic sensing system to detect foreign objects in milk. The advantage of an ultrasonic system is that it is low cost and it can detect a wide range of materials. A f<span>oreign body is any contaminated object found in food. </span>Because of the scale of multifarious food processing levels and distribution, the utilization of the food product are sometimes difficult to control, which will inevitably lead to some complaints by consumers. Milk is widely consumed in the world as it is considered as a healthy drink due to it is high nutrients levels. However, from time to time cases of milk contamination are reported. </span><span lang="MS">In this paper. t</span><span>he relationship between the foreign bodies in terms of their dimensions and the resultant amplitude are presented. Mathematical modelling were carried out based on two ultrasonic parameters i.e. acoustic impedance and wave amplitude utilizing several types of foreign bodies with different dimensions. Three types of foreign bodies which are steel, rubber and air were investigated to determine the voltage amplitude detected by the ultrasonic receiver when the foreign bodies obstructed the ultrasonic wave propagation path. The diameters of foreign bodies were in the range from 4 mm to 11 mm. The results showed good correlations between the receiver voltage and the size of foreign bodies with correlation coefficients greater than 0.95. Each foreign body also demonstrated different voltage amplitudes when several sizes of the foreign bodies were tested which showed the ability of the system to distinguish the size of each foreign body.</span>

AbstractIntra-cranial and spinal foreign body reactions represent potential complications of medical procedures. Their diagnosis may be challenging as they frequently show an insidious clinical presentation and can mimic other life-threatening conditions. Their pathophysiological mechanism is represented by a local inflammatory response due to retained or migrated surgical elements. Cranial interventions may be responsible for the presence of retained foreign objects represented by surgical materials (such as sponges, bone wax, and Teflon). Spinal diagnostic and therapeutic procedures, including myelography, chordotomy, vertebroplasty, and device implantation, are another potential source of foreign bodies. These reactions can also follow material migration or embolization, for example in the case of Lipiodol, Teflon, and cement vertebroplasty. Imaging exams, especially CT and MRI, have a central role in the differential diagnosis of these conditions together with patient history. Neuroradiological findings are dependent on the type of material that has been left in or migrated from the surgical area. Knowledge of these entities is relevant for clinical practice as the correct identification of foreign bodies and related inflammatory reactions, material embolisms, or migrations can be difficult. This pictorial review reports neuroradiological semeiotics and differential diagnosis of foreign body-related imaging abnormalities in the brain and spine.

Foreign bodies of the aerodigestive tract have been recognized for centurles. Before the early 20th century, foreign body aspiration or ingestion often meant prolonged illness and death.1 Prior to the advent of modern endoscopy, bronchotomy was the primary method of laryngotracheo-bronchial foreign body removal, and blunt metallic hooks, wire nooses, esophageal forceps, and pieces of linen attached to a piece of whalebone were used to extract foreign bodies from the esophagus.2 Not surprisingly, Weist, in 1882 (as cited by Clerf2), reported a 27.4% death rate for patients undergoing bronchotomy v a 23.2% mortality for those who were not treated. In 1911, LeRoche (as cited by Clerf2) reported the use of a rigid esophagoscope for removal of sharp foreign objects. It was Chevalier Jackson, however, who developed and refined aerodigestive endoscopy. By 1936, he was able to report a decrease in mortality from foreign bodies from 24% to 2% and a 98% success rate for bronchoscopic removal.1 Although there have been marked changes in anesthesia, equipment, and endoscopic teaching since Jackson's time, his remarkable record of success has not been significantly improved upon. The mortality for all recent series is now well below 1%, mainly due to improved anesthesia, instrumentation, and medical therapy of the suppurative complications.

In a study of 225 patients with foreign bodies in the larynx, trachea and bronchi, 77 % were 36 months of age or less. The male-female ratio was 2:1. Food or food derivatives were the causative agent in 70% of the cases, with 38% due to a portion of nut. The foreign body involved the right and left bronchus with equal frequency. A choking episode followed by an audible wheeze (55 %) was the most common presenting complaint. Obstructive emphysema was demonstrated in 60 % and was best demonstrated by inspiration-expiration chest roentgenograms or fluoroscopy. A radio-opaque object was seen in 13 %. Two hundred ten foreign objects (93 %) were removed by endoscopy. Four patients required pulmonary resection for bronchiectasis and in three patients bronchotomy was performed. Five patients expelled the foreign body spontaneously, two patients were transferred to another hospital, and one foreign body was not recovered. There was no mortality.

Foreign body ingestion is a frequent condition, with the majority of foreign bodies (FBs) tending to spontaneously proceed along the gastrointestinal tract without any major complications. A wide range of procedures are available to remove FBs; however, a real challenge exists in managing sharp, rigid, and long foreign objects, which are related to higher rates of complications. A 34-year-old man who intentionally swallowed a metallic wire of 20 cm length, presented to our ED with abdominal pain 2 weeks after the ingestion. The FB had migrated to the stomach and duodenum. Complications included perforation of the duodenum and ascending colon and a retroperitoneal abscess. FB removal was done via laparotomy, followed by the repair of perforations and damaged tissues. This case highlights the complications of a FB presence in the gastrointestinal tract for 14 days and emphasizes the importance of urgent and appropriate management of such conditions.

Abstract Hematuria, or preputial hemorrhagic discharge, is an extremely common clinical sign; it can be associated with a wide range of diseases, including, even if only rarely, penile foreign bodies. The aim of this retrospective study was to describe the diagnosis and therapy involving migration from the preputial ostium or penile urethra of a foreign body (awn grass) embedded in the connective tissue surrounding the penis, or in deeper inguinal tissues, in dogs with hematuria or preputial hemorrhagic discharge. In the selected cases, signaling, history, clinical signs, results of laboratory exams, endoscopic and ultrasonographic evaluation, and the technique used for foreign body removal were evaluated. Dogs with hemorrhagic discharge consequent to a penile foreign body represented 2% of the entire population considered. At physical examination, the most common features were the presence of swelling of the glans and hyperemia associated with a penile fistula (4/6 dogs), and pain during penile exteriorization (3/6 dogs). Laboratory results showed mild neutrophilic leukocytosis in 2/3 dogs and reticulocytosis in 1/3 dogs. Endoscopy, performed in 2/6 dogs, did not reveal any alterations associated with passage of the foreign body. Ultrasonography was useful in reaching a definitive diagnosis, identifying the position of the grass awn in 6/6 cases and permitting its removal in all dogs using an ultrasound-guided technique. This case report suggested that penile foreign bodies are a rare, but possible, cause of hematuria or hemorrhagic discharge in male dogs, and that ultrasonography is a useful technique in the making of a differential diagnosis and removal of foreign bodies.

Foreign body detection is an important aspect that affects the quality of tobacco production. This paper describes a direct foreign body detection scheme using machine vision, which uses three cameras arranged around a tobacco bale to record its multiple surfaces and directly identify foreign bodies. In this study, color sorting table method (CSTM) was first used to identify and remove color-sensitive foreign bodies; thereafter, gray threshold method and double threshold method were used to further identify and remove foreign bodies with similar colors. The experimental results indicate that the multi-step hybrid identification method proposed herein can effectively identify and remove various foreign bodies in the production process of tobacco packs, with an accuracy rate of 97.8%, which meets the industrial requirements for foreign body detection. Compared with various existing devices and methods, it has the advantages of high detection efficiency and low cost.

A class of drugs called coxibs (COX-2 inhibitors) were created to help relieve pain and inflammation of osteoarthritis and rheumatoid arthritis with the lowest amount of side effects possible. The presented paper describes a new developed, optimized and validated thin layer chromatographic (TLC)-densitometric procedure for the simultaneous assay of five coxibs: celecoxib, etoricoxib, firecoxib, rofecoxib and cimicoxib. Chromatographic separation was conducted on HPTLC F254 silica gel chromatographic plates as a stationary phase using chloroform–acetone–toluene (12:5:2, v/v/v) as a mobile phase. Densitometric detection was carried out at two wavelengths of 254 and 290 nm. The method was tested according to ICH guidelines for linearity, recovery and specificity. The presented method was linear in a wide range of concentrations for all analyzed compounds, with correlation coefficients greater than 0.99. The method is specific, precise (%RSD < 1) and accurate (more than 95%, %RSD < 2). Low-cost, simple and rapid, it can be used in laboratories for drug monitoring and quality control.

Purpose: Intravascular embolization of hemodialysis and central venous catheters is a rare but potentially serious complication. With the increasing use of catheters in medical practice, we are often faced with this type of complication. Novel, simple, and low-cost techniques are needed for foreign body extraction in order to reduce cardiovascular risks. Case Report: We describe the approach of 5 foreign body embolization cases. Case 1: a 57-year-old woman with end-stage renal failure with a complete fracture and migration of the distal extremity of a hemodialysis catheter. Case 2: a 55-year-old man with an accidental embolization of the distal portion of a hemodialysis catheter. Case 3: a 76-year-old woman with stage IV breast cancer and an accidental embolization of a central venous catheter guidewire. Cases 4 and 5: a 71-year-old woman and a 2-year-old boy with a port-a-cath embolization. All the patients underwent successful minimally invasive removal of the foreign bodies from the thoracic site using 5Fr pigtail catheters. Additional surgery was not required. No further complications, such as damage to the vascular wall, were noted. Conclusion: Our experience with the interlacing and traction pigtail show that it is a simple, practical, and low-cost technical alternative and its benefits should be widespread.

Introduction. Foreign bodies in the oesophagus are one of the more frequent non-infectious reasons for a child’s visit to the hospital emergency room. Most often, children swallow items accidentally while having fun, learning about the world with the help of their senses, as well as when eating meals. It is coins, plastic or metal fragments of objects that are usually swallowed. Also, hard pieces of food may stick to the oesophagus. Aim. The aim of the study was to analyse clinical symptoms as well as diagnostic and therapeutic procedures in patients with suspicion of the presence of a foreign body in the oesophagus. Material and methods. The authors analysed clinical data of 49 patients hospitalized in the Department of Paediatric Otolaryngology at the Medical University of Warsaw due to the suspicion or presence of a foreign body in the oesophagus. What was also analysed, was the diagnostic and therapeutic process during which the initial diagnosis was confirmed or excluded. Results. The authors analysed the symptoms with which patients came to the hospital, the diagnostic and therapeutic procedures used and the results of treatment. Attention was paid to diagnostic difficulties that may be encountered by a physician in the Admission Room, and then an otolaryngologist qualifying the patient for interventional treatment or deciding on conservative procedures. Possible complications that may occur during ezophagoscopy are described. Conclusions. Foreign bodies in the oesophagus are a common problem in the paediatric population. The most common foreign objects are coins, metal or plastic items or food. The most dangerous foreign objects are disc batteries and sharp, large objects. Diagnostic imaging includes chest and neck X-ray, and in the case of non-contrasting bodies – X-ray with barium or a cotton ball soaked in contrast. The presence of clinical symptoms and/or imaging results suggesting the presence of a foreign body in the oesophagus is an indication for oesophageal endoscopy under general anaesthesia. Both rigid esophagoscopy and the use of a flexible fiberscope are burdened with a certain degree of risk, of which the parents should be informed before those are performer.
