Complicaciones perianales causadas por agentes modeladores inyectados en glúteos / Perianal complications caused by gluteal injection of modeling agents

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)

In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

Odontogenic maxillary sinusitis associated with foreign body displacement after tooth extraction: report of an unusual case / Sinusite maxilar odontogênica por corpo estranho após extração dentária: relato de um caso incomum

Background: Odontogenic maxillary sinusitis caused by a foreign body presents diagnostic and therapeutic challenges due to its infrequent occurrence and unique characteristics compared to sinusitis originating from other sources. CaseReport:Illustrating such fact, this report presents the clinical case of a 37-year-old woman referred complaining of pain in the same region where she had extracted her upper right first molar five days before. The intraoral examination revealed the presence of an orifice in the region, suggesting oroantral communication. Imaging exams revealed opacification of the right maxillary sinus and the unexpected presence of a highly radiodense object. With the diagnosis of maxillary sinusitis due to a foreign body established, the surgical approach initially consisted of administering preoperative medication, preceded by access to the maxillary antrum using the Caldwell-Luc technique. The object was found and removed, consisting of a surgical drill. At follow-up there was complete absence of symptoms and complete closure of communication. Conclusion: Cases of odontogenic maxillary sinusitis caused by drill detachment after tooth extraction are fairly uncommon. A thorough clinical evaluation proved to be essential and the Caldwell-Luc access was effective, safe and with good postoperative results, even with the absence of standardized diagnostic and management methods(AU)

Creatively tiding over the crisis

Background: A patient with a retained intraocular metallic foreign body post?trauma was taken up for vitrectomy and intraocular foreign body removal. Unfortunately, the intraocular magnet was not available at the moment on the table! How a little bit of creativity and innovative thought helped us tide over this crisis is the content of this video. Purpose: To demonstrate magnetization of a metallic surgical instrument for temporary use in the event of unavailability of the intraocular magnet for intraocular foreign body removal. Synopsis: A ferromagnetic substance can be magnetized temporarily using an existing magnet. We obtained a general?purpose magnet and wrapped it in sterile plastic, using which we magnetized normal intraocular forceps and a Micro Vitreo Retinal (MVR) blade by giving about 20–30 strokes over the magnet in a single direction. This aligned the magnetic domains in the metal in a parallel fashion. These Do It Yourself (DIY)? magnetic instruments were then effectively utilized to remove the metallic intraocular foreign body. Highlights: The video showcases effectively harnessing the available resources and tiding over the dearth of a necessary instrument, with the right use of an innovative idea and some creativity!.

An unusual case of nasal foreign body presenting as recurrent otitis media

Otitis media (OM) is a common problem involving children. In the majority, the cause is related to dysfunction of the Eustachian tube due to bacterial or viral rhinitis and less commonly due to nasopharyngeal tumors. We present a case of recurrent OM which was evaluated and incidentally found a nasal foreign body for which the patient was asymptomatic. This nasal body was the cause of recurrent OM which is very unusual.

Rare Incidental Foreign Body in the Maxillary Sinus on Routine Radiographic Examination

Accidental entry of any foreign body into the paranasal sinus could be due to known causes or unknown causes with the patient being either symptomatic or sometimes asymptomatic. Such asymptomatic conditions make it difficult to detect the foreign body for an indefinite period which on a longer duration may lead to various complications later. Routine radiographic examination during dental checkup reports to serve a good purpose in these kinds of cases by accidental detection of such foreign bodies in the maxillofacial region leading to early diagnosis and timely management. The present paper highlights the importance of routine radiographs in detecting a rare type of foreign body (nasal stud) in the maxillary sinus in the asymptomatic patient.

Study on incidence and disease burden of foreign body in eyes in 1990 and 2019 of China / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the incidence and disease burden of foreign body in eyes in 1990 and 2019 of China.METHODS: Using the global burden of disease database in 2019, the incidence and disability adjusted life years(DALY)of foreign body in eyes in 1990 and 2019 of China were analyzed among the total population and different age groups of China.RESULTS: In 2019, the number of cases of foreign body in eyes in China was 11.2535 million, and the incidence was 79.12/10 000. The number and incidence of foreign body in eyes in 2019 decreased 12.87% and 27.49% respectively compared with those in 1990. In 2019, the DALY of foreign body in eyes in China was 181 200 person-years, and the DALY of foreign body in eyes in 2019 increased by 6.14% compared with 1990. In 2019, the age groups with the highest number of cases, incidence and DALY were all 20-54 years old, which were 8 012 600, 103.97/10 000 and 102 500 person-years, respectively. From 1990 to 2019, the incidence of foreign body in eyes in China showed a decreasing trend, average annual percentage change(AAPC)=-1.2%(95%CI: -1.8～-0.7, P<0.05), and DALY rate also showed a decreasing trend, AAPC=-0.6%(95%CI:-2.1～0, P<0.05). From 1990 to 2019, the incidence and DALY rate of foreign body in eyes in China and the World showed a downward trend. In 2019, the incidence and DALY rate of foreign body in eyes in China were significantly higher than those in the World and regions with different sociodemographic index(SDI).CONCLUSION: Although the incidence and DALY rates of foreign body in eyes in China have been decreasing in recent years, China has a large population base and the burden of foreign body in eyes is still large in the World. Active preventive measures should be taken to reduce the disease burden of foreign body in eyes.

Nanosilver alleviates foreign body reaction and facilitates wound repair by regulating macrophage polarization / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Foreign body reactions induced by macrophages often cause delay or failure of wound healing in the application of tissue engineering scaffolds. This study explores the application of nanosilver (NAg) to reduce foreign body reactions during scaffold transplantation. An NAg hybrid collagen-chitosan scaffold (NAg-CCS) was prepared using the freeze-drying method. The NAg-CCS was implanted on the back of rats to evaluate the effects on foreign body reactions. Skin tissue samples were collected for histological and immunological evaluation at variable intervals. Miniature pigs were used to assess the effects of NAg on skin wound healing. The wounds were photographed, and tissue samples were collected for molecular biological analysis at different time points post-transplantation. NAg-CCS has a porous structure and the results showed that it could release NAg constantly for two weeks. The NAg-CCS group rarely developed a foreign body reaction, while the blank-CCS group showed granulomas or necrosis in the subcutaneous grafting experiment. Both matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were reduced significantly in the NAg-CCS group. The NAg-CCS group had higher interleukin (IL)-10 and lower IL-6 than the blank CCS group. In the wound healing study, M1 macrophage activation and inflammatory-related proteins (inducible nitric oxide synthase (iNOS), IL-6, and interferon-‍γ (IFN-‍γ)) were inhibited by NAg. In contrast, M2 macrophage activation and proinflammatory proteins (arginase-1, major histocompatibility complex-II (MHC-II), and found in inflammatory zone-1 (FIZZ-1)) were promoted, and this was responsible for suppressing the foreign body responses and accelerating wound healing. In conclusion, dermal scaffolds containing NAg suppressed the foreign body reaction by regulating macrophages and the expression of inflammatory cytokines, thereby promoting wound healing.

Esferas de hidrogel relacionadas con oclusión intestinal / Bowel obstruction related to hydrogel beads

Resumen Introducción: La obstrucción intestinal por ingesta accidental de cuerpos extraños se presenta muy rara vez en la edad pediátrica debido a que del 80 al 90% de los objetos pueden pasar libremente por el tracto gastrointestinal. Caso clínico: Se aborda el caso de una paciente de sexo femenino de 1 año 2 meses quien presentó obstrucción intestinal debido a la ingesta de esferas de hidrogel (poliacrilato de sodio). Dichas esferas, que son utilizadas como juguetes didácticos o sensoriales, aumentan de 200 a 400 veces su tamaño inicial mediante la absorción de agua. Se realizó radiografía abdominal en proyección decúbito supino, donde llamó la atención el hallazgo de defecto de llenado redondeado en asa de flanco derecho, ya que las esferas de hidrogel son radiolúcidas. El diagnóstico se estableció mediante ultrasonido abdominal, donde se reportó líquido libre peritoneal con datos de suboclusión por cuerpos extraños a nivel intestinal. Se indicó tratamiento conservador, encontrando persistencia de aumento de perímetro abdominal. Se realizó enterotomía y se encontraron las esferas impactadas a 30 centímetros de la válvula ileocecal. Conclusiones: Las esferas de hidrogel son peligrosas para la población pediátrica. La evolución de la paciente fue favorable debido al conocimiento del objeto extraño ingerido. Sobresale la conducta expectante que se tuvo que desempeñar debido a que se desconocía el crecimiento de las esferas y en qué momento no podrían continuar su paso por el tracto gastrointestinal.

Abstract Background: Bowel obstruction due to accidental ingestion of foreign objects occurs rarely in children because 80 to 90% of the objects can pass freely through the gastrointestinal tract. Case report: We report a case of a 14-month-old infant who presented bowel obstruction caused by the ingestion of hydrogel beads (sodium polyacrylate). Hydrogel beads are used as sensory and didactic toys that can increase their initial size 200 to 400 times by liquid absorption. An abdominal X-ray was perfomed in anteroposterior supine projection, where a round filling defect at the loop of the right flank was detected; this came to our attention because hydrogel beads are usually radiolucent. The diagnosis was established by abdominal ultrasound where free intraperitoneal fluid was reported with data of small bowel pseudo-obstruction by foreign objects. Conservative treatment was prescribed, finding persistence of increased abdominal perimeter, so an enterotomy was performed for their removal; finding impacted hydrogel beads 30 centimeters from the ileocecal valve. Conclusions: Hydrogel beads are dangerous for the pediatric population. The evolution of the patient was favorable thanks to the knowledge of the foreign objects ingested. The expectant behavior that had to be executed, stands out because we had no knowledge as to the maximum size of the hydrogel in the gastrointestinal tract.

A case report of a transorbital penetrating intracranial injury from a motorcycle side mirror metal bar

Objective@#To present a case of transorbital penetrating intracranial injury successfully managed using a stepwise multispecialty approach.@*Methods@#This is a case report.@*Results@#A 26-year-old male presented with a motorcycle side-mirror metal bar impaled into his right orbit. He had a Glasgow Coma Scale (GCS) score of 12. Computed tomography (CT) imaging revealed the metal bar’s trajectory from the right lateral canthus, traversing the superior orbital wall and frontal lobe, resulting in contusion, intracranial hemorrhages and multiple orbital and facial fractures. Despite the severity of the injury, the right globe was found to be intact during intraoperative exploration. The transorbital approach was employed for safe removal of the penetrating object, followed by repair of full-thickness eyelid laceration and transections of the lateral and medial canthi. Subsequently, the Neurosurgery service conducted a right pterional craniotomy, debridement, and duraplasty. Upon discharge, the visual acuity on the right eye was 20/50.@*Conclusion@#Transorbital penetrating intracranial injuries are rare and result in vision loss and life-threatening complications. A transorbital approach in removing a penetrating foreign body can be adopted when injury to cerebral tissues is imminent. Individualizing the management and employing a multispecialty approach can lead to favorable outcomes.

Clinical Value Evaluation of DR Corneal Suture Ring Localization and CT 3D Reconstruction Localization of Orbital Foreign Body / 中山大学学报(医学科学版)

ObjectiveTo investigate the clinical value of DR corneal suture ring localization and CT 3D reconstruction localization of orbital foreign bodies. MethodsRetrospective analysis was performed on patients （51 cases） suspected of ocular foreign bodies admitted to our hospital from January 2016 to December 2020 At the same time， DR corneal suture ring localization and CT three-dimensional reconstruction localization of orbital foreign bodies were performed， and the detection rate of foreign bodies by the two methods was calculated to analyze the location of ocular foreign bodies. ResultsThere were 38 cases of intraorbital foreign body identified by DR corneal suture ring localization method， and 46 cases of intraorbital foreign body identified by CT three-dimensional reconstruction localization method. The accuracy of CT three-dimensional reconstruction localization method was 90.20%， which was higher than that of DR corneal suture ring localization method 74.51% （P<0.05）. Intraocular foreign bodies in 23 cases could be distinguished by DR corneal suture ring localization， and 25 cases by CT 3D reconstruction localization. The maximum diameter of intraocular foreign bodies that could be distinguished by CT 3D reconstruction localization was （2.65±0.14） mm. The diameter of intraspherical foreign body was （2.94±0.36） mm （P<0.05） lower than that which could be distinguished by DR corneal suture ring localization method. The results of DR corneal suture ring localization of orbital foreign body showed no difference compared with the results of CT 3D reconstruction localization （P>0.05）. Forty cases of high density images inside and outside the eye could be clearly distinguished by CT 3D reconstruction. By using DR corneal suture ring localization method， 23 cases were confirmed to be intraocular high-density shadows， and 15 cases could not be confirmed to be intraocular high-density shadows （P < 0.05）. ConclusionsFor the location of intraorbital foreign bodies， CT three-dimensional reconstruction can be used as a conventional method for locating ocular foreign bodies with high resolution and accuracy， and can detect fine metal particles inside the eyeball. Meanwhile， for a few small foreign bodies in the iris root， ciliary body and lateral suspension ligament， it is necessary to locate orbital foreign bodies with DR corneal suture ring.

A Case of Foreign Body Aspiration Mimicking Asthma in Adult

@#Foreign body aspiration is uncommon in adults who have no known risk factors such as mental retardation, poor dentition, or advanced age. Adults with foreign body aspiration are commonly misdiagnosed with bronchial asthma, however, does not respond to standard bronchodilator treatment. A thorough history-taking, focused physical examination and a high index of suspicion is crucial in making the correct diagnosis. This paper reports an interesting case of a 41- year-old woman with an undetected 10-year long foreign body aspiration which was misdiagnosed as bronchial asthma.

Incidence and related factors of umbilical venous catheter tip migration / 中华围产医学杂志

Objective:To analyze the incidence and the related factors of umbilical vein catheter (UVC) tip migration within 7 d after umbilical vein catheterization.Methods:This prospective study involved neonates who were successfully indwelled with UVCs in the Department of Neonatology of Gansu Provincial Women and Child-care Hospital from June 2020 to December 2021. The position of the UVC tip, length of umbilical stump, body weight, and abdominal circumference were recorded after the UVCs were inserted successfully, and the changes in these four data at 2, 24, 48, 72 h, and 7 d after catheterization were analyzed and compared. All the subjects were divided into the non-migrate group, inward migration group, and outward migration group. Chi-square test, Mann-Whitney U test, or Kruskal Wallis H test were used for statistical analysis. Results:A total of 157 newborns were enrolled, with 51 cases in the inward migration group, 62 cases in the outward migration group, and 44 cases in the non-migrate group. There were no significant differences among the three groups regarding gestational age, birth weight, gender, born through cesarean section, age at the time of catheterization, use of sedation, and feeding modes (all P>0.05). The migration rates of UVCs tip at 2, 24, 48, 72 h, and 7 d after catheterization were 0, 27.4% (43/157), 27.2% (31/114), 25.3% (21/83), and 29.0% (18/62), respectively. The cumulative migration rates at 24, 48, 72 h, and 7 d were 27.4% (43/157), 47.1% (74/157), 60.1% (95/157), and 72.0% (113/157), respectively. Compared with the non-migrate group, the inward migration group had a shorter umbilical cord stump at 24 and 48 h [0.5 cm (0.4-0.5 cm) vs 0.6 cm (0.5-0.8 cm); 0.4 cm (0.3-0.5 cm) vs 0.5 cm (0.5-0.6 cm), Z=－5.55 and －3.69, both P<0.05], less abdominal circumference increment at 48 and 72 h [0.6 cm (0.5-1.0 cm) vs 0.9 cm (0.7-1.2 cm); 0.6 cm (0.3-0.9 cm) vs 0.9 cm (0.7- 1.3 cm), Z=－2.03 and －2.09, both P<0.05)], and more weight loss percentage [－4.7% (－6.0%-－3.6%) vs －3.1% (－3.7%-－2.2%); －6.0% (－7.5%-－5.0%) vs －3.9% (－5.1%-－2.4%), Z=－3.75 and －2.96, both P<0.05]. The abdominal circumference increased more in the outward migration group at 24, 48, 72 h, and 7 d than those in the non-migrate group [1.6 cm (0.9-1.9 cm) vs 0.7 cm (0.5-0.9 cm); 1.5 cm (1.2-1.8 cm) vs 0.9 cm (0.7-1.2 cm); 1.7 cm (1.3-1.9 cm) vs 0.9 cm (0.7-1.3 cm); 1.6 cm (1.1-1.9 cm) vs 0.9 cm (0.6-1.3 cm), Z=－4.82, －4.79, －3.74, and －3.09, all P<0.05]. Conclusion:The incidence of UVC tip migration is high, which could be affected by dryness and retraction of the umbilical cord stump and the change in neonatal abdominal circumference and body weight.
