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)

Prognostic value of a classification and regression tree model in patients with open-globe injuries

Objective@#To evaluate the accuracy of the Classification and Regression Tree (CART) model in prognosticating visual outcomes of patients with open-globe injuries@*Methods@#This was a retrospective, single-center, cohort study of patients with open-globe injuries seen over a two-year period. Purposive sampling of hospital medical records was done to collect data from both in- and out-patient cases. The CART algorithm was utilized to determine the predicted visual outcome for each case, and the accuracy of prognostication was measured by computing for sensitivity, specificity, positive predictive value, and negative predictive value. The area under the receiver operating characteristic curve was used to check its discriminatory capability.@*Results@#A total of 65 eyes (65 patients) with the following diagnoses based on the Birmingham Eye Trauma Terminology (BETT) classification were included: penetrating eye injury (n=58), globe rupture (n=2), and intraocular foreign body (n=5). Majority were male patients (81.5%) in the 17-39 year age group (40%). The sensitivity and specificity of CART were 100% (95% CI 93.6 to 100%) and 77.8% (95% CI 40 to 97.2%), respectively, with an overall accuracy of 96.9% (95% CI 89.3 to 99.6%). Area under the curve (AUC) was statistically significant at 0.89 (95% CI 0.79 to 0.95), indicating that the CART model can discriminate vision survival versus no vision.@*Conclusion@#The CART model demonstrated high accuracy in prognosticating visual outcomes after an openglobe injury in the local setting. It may be used as a helpful tool to guide treatment decisions in open-globe injuries.

Aspectos gerais do retículo peritonite traumática em bovinos / General aspects of traumatic reticulum peritonitis in cattle / Aspectos generales de la peritonitis del retículo traumático en ganado

A Retículo Peritonite Traumática está diretamente ligada à ingestão de objetos metálicos perfuro cortantes, como pregos e pedaços de arame, que podem penetrar ou perfurar a parede do retículo. Embora a ocorrência de corpos estranhos de alumínio seja rara, outros elementos, como fios de pneus usados para fixar lonas em silagens e até cerdas de arame de escovas utilizadas em pequenos aeroportos, têm sido registrados como causas dessa afecção. A ingestão desses objetos pode resultar em lesões no retículo, desencadeando episódios de retículo peritonite traumática e suas sequelas, como pericardite traumática, inflamação do fígado, abscessos no baço e muito mais. Os sinais clínicos podem variar, mas incluem comportamento anormal, motilidade reduzida do rúmen, fezes mal digeridas, febre e sinais de dor. O diagnóstico baseia-se na avaliação dos sinais clínicos do animal, juntamente com exames complementares, como hemograma, bioquímico, ultrassom e radiografia. É importante considerar as alterações hematológicas, como leucocitose e hiperfibrinogenemia, como indicadores-chave desta afecção. O diagnóstico também envolve testes de dor ao corpo estranho. O tratamento pode ser conservativo ou cirúrgico. A abordagem conservativa envolve a administração de antibióticos, anti-inflamatórios e soluções intravenosas, além do tratamento de deficiências nutricionais subjacentes. A opção cirúrgica exige a remoção do corpo estranho do retículo, seguida de cuidados pós-operatórios.

Traumatic Reticulum Peritonitis this directly linked to the ingestion of sharp metallic objects, such as nails and pieces of wire, which can penetrate or pierce the wall of the reticulum. Although the occurrence of aluminum foreign bodies is rare, other elements, such as tire wires used to attach tarpaulins to silage and even wire bristles from brushes used in small airports, have been recorded as causes of this condition. Ingestion of these objects can result in damage to the reticulum, triggering episodes of traumatic reticulum peritonitis and its sequelae, such as traumatic pericarditis, liver inflammation, spleen abscesses and more. Clinical signs may vary but include abnormal behavior, reduced rumen motility, poorly digested feces, fever and signs of pain. The diagnosis is based on the evaluation of the animal's clinical signs, together with complementary tests, such as blood count, biochemistry, ultrasound and radiography. It is important to consider hematological changes, such as leukocytosis and hyperfibrinogenemia, as key indicators of this condition. Diagnosis also involves foreign body pain testing. Treatment can be conservative or surgical. The conservative approach involves administering antibiotics, anti-inflammatories and intravenous solutions, in addition to treating underlying nutritional deficiencies. The surgical option requires removal of the foreign body from the reticulum, followed by post-operative care.

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.

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.

Renal abscess induced by fish bone ingestion: a case report / 中华泌尿外科杂志

Renal abscess caused by fish bone ingestion is extremely rare and has not been reported in the literature. A male patient presented with a 1-week history of flank pain and a 2-day history of fever. Urinary ultrasound and CT scan showed an irregular hypodense lesion in the left kidney and blurred thickening of the descending colon wall. Three-dimensional CT reconstruction images revealed a needle-like foreign body, which perforated from the descending colonic lumen to the left kidney. The patient had accidentally eaten fish bone one week prior. On the basis of clinical data, the diagnosis of renal abscess caused by foreign body was suspected. Accordingly, laparotomy was performed, the abscess was drained, and the colon was repaired. The foreign body was confirmed to be fish bone. The postoperative condition of the patient was uneventful, and the patient remained well in the 3 months' follow-up without any further complaints.
