Acidente crotálico seguido por primeiro episódio psicótico: um folclore clínico / Rattlesnake bite accident followed by first psychotic episode: a clinical folklore / Accidente crotálico seguido de primer episodio psicótico: un folclore clínico

Introdução: Acidentes ofídicos são doenças negligenciadas e constituem uma parcela importante da morbidade de pessoas em idade produtiva que vivem em zonas rurais. A maior parte dos seus efeitos a curto prazo é amplamente conhecida, especialmente aqueles de natureza clínica; no entanto, ainda se observa lacuna importante do conhecimento das consequências a longo prazo de tais agravos, notadamente as de ordem psíquica. Este artigo relata um caso de adoecimento mental subsequente a um acidente crotálico e gera reflexões de âmbito cultural e fisiopatológico a respeito das sequelas de tais eventos. Apresentação do caso: Trata-se de adolescente residente no interior baiano que foi vítima de mordedura por cascavel e teve necessidade de hospitalização em unidade de terapia intensiva. Observou-se que, mesmo após melhora clínica, iniciou com sintomas psicóticos prodrômicos e progrediu para piora mental grave, que culminou em internação psiquiátrica e diagnóstico de esquizofrenia no decorrer dos meses seguintes. Conclusões: Nota-se, neste caso, correlação direta entre esses dois eventos; mas, em razão da escassez de trabalhos científicos que abordem tais questões, depreende-se que é preciso investigar e estudar com maior profundidade possíveis associações entre acidentes crotálicos e psicoses.

Introduction: Snakebites are neglected diseases and constitute an important part of the morbidity of working-age people who live in rural areas. Most of their short-term effects are widely known, especially those of a clinical nature; however, there is still an important gap in the knowledge of the long-term consequences of such injuries, notably those of a psychotic nature. This article aims to report a case of mental illness subsequent to a rattlesnake bite accident and generate cultural and pathophysiological reflections regarding the consequences of such events. Case presentation: An adolescent residing in the interior of the state of Bahia was bitten by a rattlesnake and required hospitalization in an intensive care unit. It was observed that even after clinical improvement, the case started with prodromal psychotic symptoms and progressed to severe mental deterioration that culminated in psychiatric hospitalization and diagnosis of schizophrenia over the following months. Conclusions: In this case, there was a direct correlation between these two events, but because of the scarcity of scientific works that address such issues, it is necessary to investigate and study in greater depth possible associations between snakebite accidents and psychoses.

Introducción: Las mordeduras de serpientes son enfermedades desatendidas y constituyen una parte importante de la morbilidad de las personas en edad laboral que viven en zonas rurales. La mayoría de sus efectos a corto plazo son ampliamente conocidos, especialmente los de carácter clínico; sin embargo, todavía existe un importante vacío en el conocimiento de las consecuencias a largo plazo de este tipo de lesiones, en particular las de carácter psíquico. Este artículo tiene como objetivo informar un caso de enfermedad mental posterior a un accidente crotálico y generar reflexiones culturales y fisiopatológicas sobre las consecuencias de tales eventos. Presentación del caso: Se trata de un adolescente residente en el interior de Bahía que fue mordido por una serpiente cascabel y requirió hospitalización en unidad de cuidados intensivos. Se observó que, aún después de la mejoría clínica, comenzó con síntomas psicóticos prodrómicos y progresó a un deterioro mental severo que culminó con hospitalización psiquiátrica y diagnóstico de esquizofrenia en los meses siguientes. Conclusiones: En este caso, existe una correlación directa entre estos dos eventos pero, debido a la escasez de trabajos científicos que aborden tales cuestiones, parece necesario investigar y estudiar con mayor profundidad posibles asociaciones entre accidentes crotálicos y psicosis.

Recurrent Achilles Tendon Rupture in Multiple Sites as a Primary Manifestation of Systemic Lupus Erythematosus in a 32-Year-Old Patient: A Case Report.

The Achilles tendon is vital for walking and running, but it's also the most frequently ruptured tendon. Ruptures often occur without direct trauma and present with acute posterior ankle/heel pain. Various factors like age, biomechanical properties, degeneration, and mechanical factors influence susceptibility to rupture. Mechanisms of injury vary, including weight-bearing forefoot pushing off and sudden dorsiflexion of the ankle. Management goals focus on minimizing morbidity, swift recovery, and preventing complications through tailored interventions. Systemic lupus erythematosus (SLE) can also contribute to tendon rupture, especially with prolonged corticosteroid use. A 32-year-old female presented to the ER after injuring her left foot during a basketball game. She was diagnosed with an Achilles tendon rupture and underwent surgery to repair it. However, she experienced delayed wound closure and needed a skin graft. Two months later, she suffered another rupture in a different location, requiring a tendon transfer surgery. She was finally diagnosed with SLE after tests by the Rheumatology Department. Treatment commenced, and she began rehabilitation four weeks post-surgery. Surgical management of ruptured Achilles tendon involves techniques like open repair, percutaneous repair, mini-open repair, and augmentative repair. Open repair involves a direct approach with a posteromedial incision to align tendon stumps using various stitching techniques. Conservative treatment involves immobilization and non-weight-bearing for at least four weeks post surgery. For rare cases of Achilles tendon rupture caused by lupus, treatment focuses on managing the underlying disease with medications like hydroxychloroquine and glucocorticosteroids. Comprehensive evaluation, including musculoskeletal assessment, is crucial for lupus patients. SLE needs to be considered as a potential cause, especially in cases of recurrent ruptures or additional musculoskeletal symptoms. Surgical management should be tailored to individual patient needs, while also considering surgeon proficiency and preferences.

Endodontic apical surgery with novel endoscope: Three-case series.

Successful apical surgery relies on effective magnification and illumination. In the field of endodontics, the microscope has emerged as the predominant tool for meeting these requirements. The rigid endoscope is also a valuable instrument in apical surgery. This study introduces three cases demonstrating the application of endoscope technology in endodontic apical surgery. The first case employs a soft endoscope for treating an anterior tooth with apical periodontitis, the second integrates an endoscope with new attachments for a premolar, and the third combines an endoscope, attachments and navigation for the lower first molar surgery. It revealed that endoscopes offer certain advantages that are not achievable with microscope-assisted surgery, these cases had a great outcome. In the future, a broader application of endoscopic technology in various procedures is anticipated.

A clinical dilemma: Performing or avoiding root instrumentation in the treatment of the acute phase of endodontic-periodontal lesions? A case report.

BACKGROUND: This study presents the diagnois, management, and tissue response to an acute periodontal lesion with deep pocketing affecting a maxillary central incisor in a young patient devoid of caries or a history of periodontitis. METHODS: Clinical and radiographic examinations facilitated the diagnosis of the pathology as an endoperiodontal lesion (EPL) with root damage, exhibiting supracrestal invasive root resorption. Orthograde endodontic therapy was employed to decontaminate and seal the endodontic space. The resorptive site was treated through the endodontic access, debrided, and sealed. No periodontal therapy (surgical or nonsurgical) was performed. No mechanical instrumentation was performed within the pocketed root surface. RESULTS: At 6-month and 1-year follow-ups after endodontic therapy the periodontium displayed a physiologically healthy condition without pus or inflammation, exhibiting a circumferential probing depth of 2 mm, and absence of tooth mobility. These favorable outcomes persisted throughout a 4-year follow-up period. CONCLUSIONS: The spontaneous healing of pocketing and abscess occurred without mechanical root instrumentation following endodontic therapy and treatment of external invasive root resorption in an EPL. KEY POINTS: Accurate diagnosis and identification of relevant etiologic factors are pivotal for effectively managing endodontic-periodontal lesions. Once a diagnosis is established, the therapy focuses on eliminating the primary cause, followed by a subsequent diagnostic phase after healing. The definitive understanding of the diagnosis and etiology of endodontic-periodontal lesions often becomes clear in retrospect, based on the outcomes of the therapy. When probing acute periodontal lesions, deep probing depths may occur without permanent loss of periodontal attachment. If the acute lesion was not induced by a periodontal cause and if no periodontal etiology arises secondarily, resolving the primary cause of the endoperiodontal lesion can lead to the spontaneous resolution of the pocketing. This results in spontaneous healing of periodontium without the need for intentional periodontal therapy. A clinical dilemma arises when considering periodontal treatment during the acute inflammatory phase of endo-periodontal pathology. It is advisable to refrain from mechanical root instrumentation particularly if a clear periodontal cause is not apparent, to prevent from iatrogenic damage to periodontal fibers and the potential risk of gingival recessions. However, this does not imply avoiding periodontal therapy entirely for every case. Rather, it is recommended to delay the decision on root instrumentation until a new diagnostic phase is conducted following the healing of the endodontic etiology.

A case report of pegcetacoplan use for a pregnant woman with paroxysmal nocturnal hemoglobinuria.

Background: Paroxysmal nocturnal hemoglobinuria (PNH), a rare hematologic disease, is associated with high maternal and fetal mortality rates. Only 1 medication approved for PNH, the complement component 5 inhibitor eculizumab, has published evidence of use during pregnancy. Key Clinical Question: What were the circumstances and outcomes of the first use of pegcetacoplan, a complement component 3 inhibitor, by a pregnant woman with PNH? Clinical Approach: The patient, with a history of 2 miscarriages and a suboptimal response to eculizumab, had hematologic improvement after switching to pegcetacoplan. She continued pegcetacoplan throughout her pregnancy. At gestational week 30, she developed abruptio placentae and breakthrough hemolysis. She delivered a normal-appearing male infant via emergency cesarean section. The breakthrough hemolysis resolved quickly with short-term intensive pegcetacoplan dosing and add-on eculizumab. To date, her laboratory values remain normal, and she has had no thromboembolic events; her son has not demonstrated growth defects. Conclusion: This is the first report of pegcetacoplan treatment for PNH throughout pregnancy. The mother recovered promptly from breakthrough hemolysis that prompted an emergency delivery. Her son, who was born prematurely but healthy, has developed normally.

Mechanical thrombectomy for cerebrovascular occlusion in a patient with situs inversus.

Situs inversus is a rare congenital abnormality characterized by mirror-image transposition of the major visceral organs and vessels. Few reports have discussed the use of mechanical thrombectomy in acute ischemic stroke with situs inversus. We present such a case, to raise awareness and deepen the knowledge on these cases. A 44-year-old man was admitted to our hospital with sudden-onset dysarthria and left-sided paresis. Computed tomography (CT) angiography revealed situs inversus and occlusion in the internal carotid artery. First, intravenous tissue plasminogen activator was administered, followed by immediate reperfusion with mechanical thrombectomy. We achieved thrombolysis in cerebral infarction grade 3. After the procedure, the patient fully recovered. Prompt diagnosis is crucial for rapid recanalization in patients with vascular anomalies such as situs inversus.

Minimally traumatic extraction of fractured bilateral maxillary canine teeth using a piezoelectric surgical unit in an African lion (Panthera leo).

IMPORTANCE: Canine extraction of large carnivores can pose significant risk due to extensive tissue damage during aggressive bone reduction. This report highlights a rare instance in which the use of a piezoelectric surgical unit (PSU) for maxillary canine extraction in a large carnivore resulted in successful outcomes with minimal tissue damage. CASE PRESENTATION: A 10-year-old male African lion presented with decreased appetite because of bilateral maxillary canine fractures. Intraoral radiographs revealed enlarged root canals and periapical radiolucency of the fractured canines, leading to a diagnosis of periapical periodontitis and pulpitis. To extract the right maxillary canine, conventional method using hand instrument failed to achieve adequate luxation, necessitating the use of the flat blade of the PSU to sever the periodontal ligament. The left maxillary canine was extracted using PSU from the beginning, and the extraction time was markedly shortened by using PSU without additional alveolar bone damage or bleeding. CONCLUSION AND RELEVANCE: This case demonstrated that utilizing PSU for canine extraction in a lion resulted in periodontal ligament separation, reducing damage to the alveolar bone and shortening surgical time. It suggests the promising application of PSU in tooth extraction for large wild animals, indicating its potential significance in veterinary dentistry.

Rare genetic cerebrotendinous xanthomatosis cases (CTX) without cholestanol elevation but with prominent cholesterol-rich tendon xanthomas.

Cerebrotendinous xanthomatosis (CTX) is a rare inherited metabolic disease attributed to the mutation of the gene CYP27A1, resulting in sterol 27-hydroxylase deficiency characterized by deposition of cholestanol and cholesterol in several tissues, like the central nervous system and tendons. Furthermore, cataracts, gallstones, diarrhea and premature atherosclerosis have been reported. Nonetheless, clinical development is extremely heterogeneous in CTX. We report here two cases of CTX genetic alteration in the absence of cholestanol elevation in plasma and tendons but with prominent xanthomas. We propose that CTX may not be characteized by increased plasma cholestanol concentration due to alteration in the sterol 27-hydroxylase gene, but is a more complex pathology where there is significant genetic heterogeneity caused by various CYP27A1 mutations.

Mitral Valve Replacement for Bulky, Calcified Mitral Annulus: A Case Report.

Calcification of the mitral valve annulus is common in patients on dialysis. The growing number of individuals receiving dialysis has been accompanied by an increase in cases necessitating surgical intervention for mitral valve annulus calcification. In this report, we present a severe case characterized by bulky calcification of the mitral annulus, which was managed with mechanical mitral valve replacement. A 61-year-old man on dialysis presented with chest pain upon exertion that had persisted for 3 months. Cardiac echocardiography revealed severe mitral stenosis and regurgitation, accompanied by cardiac dysfunction. During surgery, an ultrasonic aspiration system was employed to remove the calcification of the mitral valve annulus to the necessary extent. Subsequently, a mechanical mitral valve was sutured into the supra-annular position. To address the regurgitation, the area surrounding the valve was sewn to the wall of the left atrium. Postoperative assessments indicated an absence of perivalvular leak and demonstrated improved cardiac function. The patient was discharged on postoperative day 22. We describe a successful mitral mechanical valve replacement in a case of extensive circumferential mitral annular calcification. Even with severe calcification extending into the left ventricular myocardium, we were able to minimize the decalcification process. This approach enabled the performance of mitral mechanical valve replacement in a high-risk patient on dialysis, thus expanding the possibilities for cardiac surgery.

A Symptomatic Mucinous Cystic Neoplasm of the Mesentery: A Case Report.

Mucinous cystic neoplasms (MCNs) are rare tumors primarily observed in the pancreas but occasionally found in other locations such as the retroperitoneum, ovary, liver, and spleen. These neoplasms are histologically classified based on the degree of dysplasia, with some associated with invasive carcinoma. Colorectal surgeons infrequently encounter MCNs. Mesenteric MCNs pose a diagnostic challenge secondary to their atypical location, subtle histology, and lack of specific biochemical markers. In this context, we present a case involving a 68-year-old female who initially presented with an assumed ovarian mass. Subsequent exploration revealed a 12 cm MCN situated in the sigmoid mesentery, a location seldom associated with these tumors. The patient underwent laparotomy with successful resection and recovery. Histopathological analysis confirmed the neoplasm's mucinous epithelium with a complex papillary architecture. Immunohistochemical staining supported the diagnosis, revealing positivity for CK7, SATB2, and CDX2.

Finding Medical Photographs of Patients Online: Randomized, Cross-Sectional Study.

BACKGROUND: Photographs from medical case reports published in academic journals have previously been found in online image search results. This means that patient photographs circulate beyond the original journal website and can be freely accessed online. While this raises ethical and legal concerns, no systematic study has documented how often this occurs. OBJECTIVE: The aim of this cross-sectional study was to provide systematic evidence that patient photographs from case reports published in medical journals appear in Google Images search results. Research questions included the following: (1) what percentage of patient medical photographs published in case reports were found in Google Images search results? (2) what was the relationship between open access publication status and image availability? and (3) did the odds of finding patient photographs on third-party websites differ between searches conducted in 2020 and 2022? METHODS: The main outcome measure assessed whether at least 1 photograph from each case report was found on Google Images when using a structured search. Secondary outcome variables included the image source and the availability of images on third-party websites over time. The characteristics of medical images were described using summary statistics. The association between the source of full-text availability and image availability on Google Images was tested using logistic regressions. Finally, we examined the trend of finding patient photographs using generalized estimating equations. RESULTS: From a random sample of 585 case reports indexed in PubMed, 186 contained patient photographs, for a total of 598 distinct images. For 142 (76.3%) out of 186 case reports, at least 1 photograph was found in Google Images search results. A total of 18.3% (110/598) of photographs included eye, face, or full body, including 10.9% (65/598) that could potentially identify the patient. The odds of finding an image from the case report online were higher if the full-text paper was available on ResearchGate (odds ratio [OR] 9.16, 95% CI 2.71-31.02), PubMed Central (OR 7.90, 95% CI 2.33-26.77), or Google Scholar (OR 6.07, 95% CI 2.77-13.29) than if the full-text was available solely through an open access journal (OR 5.33, 95% CI 2.31-12.28). However, all factors contributed to an increased risk of locating patient images online. Compared with the search in 2020, patient photographs were less likely to be found on third-party websites based on the 2022 search results (OR 0.61, 95% Cl 0.43-0.87). CONCLUSIONS: A high proportion of medical photographs from case reports was found on Google Images, raising ethical concerns with policy and practice implications. Journal publishers and corporations such as Google are best positioned to develop an effective remedy. Until then, it is crucial that patients are adequately informed about the potential risks and benefits of providing consent for clinicians to publish their images in medical journals.

Hyperbaric oxygen treatment in bilateral orchiopexy and post-circumcision haematoma in a thrombocytopenic patient with Noonan syndrome.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

Retrosternal herniation of transverse colon following minimal invasive esophagectomy causing dysphagia: A case report.

INTRODUCTION AND IMPORTANCE: Minimally invasive esophagectomy has emerged as the established standard for treating esophageal cancer. The gastric graft is usually placed in the posterior mediastinum or the retrosternal tunnel for reconstruction. Hiatal hernia occurrence is more common in the posterior mediastinal reconstruction and is more frequently observed in laparoscopic compared to open approach. On the other hand, retrosternal hernia is a rare complication that deserves greater attention, considering the increasing popularity of retrosternal reconstruction in esophageal cancer treatment. CASE PRESENTATION: We present the case of a 55-year-old male patient who underwent minimally invasive esophagectomy with retrosternal reconstruction using gastric conduit and cervical anastomosis. After four years, the patient experienced symptoms, including dyspnea and chest pain. CT scan revealed transverse colon herniation into the retrosternal tunnel. CLINICAL DISCUSSION: Our diagnosis was retrosternal herniation of the transverse colon. Although there was no sign of obstruction, the abundant colon in the retrosternal space caused mass effect symptoms. For that reason, we performed laparoscopic surgery to release the herniated organ and close the hernia hole. Postoperatively, the patient had a satisfactory recovery, and a follow-up CT scan confirmed the absence of any remaining herniated organs. CONCLUSION: While hiatal hernia is a well-known complication in minimally invasive esophagectomy, retrosternal hernia is a lesser-known entity. Surgical intervention is necessary to alleviate symptoms caused by herniation or address complications such as strangulation. The occurrence of retrosternal hernia warrants further attention and research in the future.

First Case Report of Bilateral Parotid Lymphoepithelial Carcinoma.

Background/Aim: The parotid is the largest salivary gland and is located anteriorly to the sternocleidomastoid muscle and laterally to the ramus of the mandible. Neoplasms in this gland are relatively rare, with 80% being benign and 20% malignant, primarily represented by mucoepidermoid carcinoma. In the head and neck region, lymphoepithelial carcinoma (LEC) accounts for 0.4% of malignant salivary gland tumors. Case Report: A 35-year-old man with no previous comorbidities was admitted to a Head and Neck Surgery Specialty Service for a painless right cervical mass of uncertain growth. Extensive diagnostic investigation revealed involvement of the contralateral parotid, associated with systemic lymph node enlargement. Thus, adjuvant radiotherapy was decided by the treating team. Conclusion: This case confirms the heterogeneous features and distinctive behavior that the disease can present, as seen with bilateral parotid LEC.

Understanding Creutzfeldt-Jakob disease in Iran: a systematic review of case reports.

OBJECTIVE: To systematically review the reported cases of Creutzfeldt-Jakob disease (CJD) in Iran. METHODS: A comprehensive literature review of CJD cases in Iran was undertaken using the PubMed®, Scopus® and Google Scholar databases. In addition, the Iranian database MagIran was searched for Persian language reports. Case selection used the following criteria: (i) patients of Iranian origin; (ii) publication in peer-reviewed journals or reputable medical databases; (iii) a definitive diagnosis of CJD based on established diagnostic criteria. RESULTS: Thirteen cases from twelve reports were included in this systematic review. The majority of the cases were female (11 of 13; 84.6%). The mean ± SD age of patients at hospital admission was 59.38 ± 7.44 years. The findings of the case review suggested that the prevalence of CJD in Iran is not fully established. CJD may be misdiagnosed alongside other clinical signs. The most prevalent early indications of the disease were psychiatric and neurological in nature. A considerable delay in diagnosis was observed in some cases and there was a shortage of brain autopsy records. CONCLUSION: Efforts to improve diagnostic capabilities, promote awareness and establish monitoring systems are necessary for managing the challenges of providing an early diagnosis of CJD in Iran.

Acute left anterior descending artery occlusion after IVUS leading to urgent percutaneous coronary intervention complicated with coronary perforation: Case report.

Background: Intravascular ultrasonography (IVUS) has become an important complementary tool in interventional cardiology, both for preprocedural planning and for optimizing the performance of percutaneous coronary intervention (PCI). However, this tool is not free of potential complications, because of that it is essential to be aware of them and their management. Over time, new uses of IVUS have emerged, and it is currently a potential tool for predicting the risk of coronary perforation. Case report: We present the clinical case of a 51-year-old male patient who was admitted in the context of post-infarction angina. During coronary angiography, the patient presented with two acute complications, one of them associated with IVUS and the other associated with severe coronary calcification that predisposed to coronary perforation. Both complications were successfully treated. Conclusion: IVUS, although a very useful imaging tool before and during PCI, is not without risk. The overall rate of complications with certain or possible relation to IVUS is 3.9%. Vascular spasm is the most frequent complication and acute vascular occlusion, with the need for emergency coronary artery by-pass grafting, the least frequent. On the other hand, IVUS can predict the risk of developing other complications, such as coronary perforation, by means of the C-CAT sign. Knowledge of the possible complications during PCI and the rapid procedure of the hemodynamic team allows adequate management of these potentially fatal complications.

Fatal Septic Shock Due to Aeromonas Hydrophila in a Cirrhotic Patient; a Case Report.

Aeromonas hydrophila has been identified as a causative agent of necrotizing fasciitis and myonecrosis, with most reported cases having a connection to aquatic-related trauma. Cases without such trauma history are rare in existing literature. Here, we present the case of a 56-year-old cirrhotic patient who lacked any prior aquatic-related trauma and arrived at the emergency department in a state of septic shock. The suspected route of entry was through necrotizing fasciitis and myonecrosis in his left forearm. Unfortunately, the patient succumbed to multi-organ failure and passed away within 12 hours of admission to the emergency department.

Difficult endotracheal intubation in a patient with progressed tracheobronchopathia osteoplastica: A case report.

Tracheobronchopathia osteoplastica is a rare condition involving large airways with multiple bone and cartilage nodules in the tracheobronchial submucosa. This can cause tracheal stenosis, leading to difficulty in endotracheal intubation. A 79-year-old female patient, who had a history of successful endotracheal intubation for general anesthesia 8 years prior, was scheduled for abdominal surgery. Preoperative chest computed tomography and bronchoscopy revealed slight progression of tracheobronchopathia osteoplastica. Attempts to intubate with a smaller endotracheal tube failed; even the smaller endotracheal tube could barely pass. Mechanical ventilation was successfully administered and the surgery was completed without complications. The use of a smaller endotracheal tube may be beneficial for managing difficult airways in patients with tracheobronchopathia osteoplastica. Chest CT and bronchoscopic examination may be beneficial for evaluating the airway and determining the most appropriate airway management strategy. However, relying solely on these measures may lead to unexpected challenges because there is no established method to evaluate airway in patient with tracheobronchopathia osteoplastica. It is crucial for anesthesiologists to be aware of the potential existence of rare conditions such as tracheobronchopathia osteoplastica and be prepared to handle anticipated or unanticipated difficult airway management.
