He was a retired electrician who had been exposed to construction dust and asbestos fibers for decades. Chest computed tomography (CT) revealed partially calcified pleural plaques and posterior left lower lobe rounded atelectasis (RA) with “comet tail sign” [&lt;span&gt;1&lt;/span&gt;] (Figure 1A,B). Retrospectively, the RA appeared to remain the same shape and size since 2017. Positron emission tomography revealed &lt;sup&gt;18&lt;/sup&gt;F-fluorodeoxyglucose uptake in the right upper lobe primary tumor, but not in the pleural plaque or RA (Figure 1C–E). Subsequently, the patient was treated with carboplatin/etoposide plus atezolizumab as first-line chemotherapy in July 2023. Soon after atezolizumab infusion, he developed a transient fever; thereafter, he gradually complained of worsening dyspnea on exertion, with mild desaturation. On day 9 after chemotherapy induction, chest CT showed a new-onset consolidative shadow on the left lower lung that appeared around the preexisting RA (Figure 2A,B). The laboratory test results, including infectious serology and culture results, were unremarkable. Additional inflammatory serologies (antinuclear and antineutrophil cytoplasmic antibodies) were negative. Due to hypoxemia, further diagnostic studies, such as bronchoscopy, could not be conducted. We suspected that the lesion was consistent with atezolizumab-induced interstitial lung disease (immune-related adverse event [irAE]) and started intravenous prednisolone (40 mg daily). After the initiation of steroid treatment, his hypoxemia and lung shadow were almost completely cleared (Figure 2C,D), which supported the diagnosis of irAE pneumonia in RA. We decided to refrain from atezolizumab treatment and continued carboplatin/etoposide therapy alone without recurrence of irAEs.&lt;/p&gt;&lt;p&gt;RA [&lt;span&gt;2&lt;/span&gt;], also known as “folded lung” or “Blesovsky's syndrome,” is a subtype of lung atelectasis caused by invagination of the redundant visceral pleura [&lt;span&gt;3&lt;/span&gt;].

RA usually maintains the same volume and even shrinks on serial scans [&lt;span&gt;4-6&lt;/span&gt;], which supports the benign feature of the lesion and justifies careful follow-up without intervention. However, there are some reports of RA that gradually enlarge and eventually necessitate surgical biopsy or excision [&lt;span&gt;7&lt;/span&gt;].

{"title":"An Accuracy Assessment: Responses to Mycoplasma Pneumoniae Pneumonia-Related Questions by Different Artificial Intelligence Tools","authors":"Shuang Li","doi":"10.1111/crj.70005","DOIUrl":"10.1111/crj.70005","url":null,"abstract":"<p>With the rapid development of socio-economic technology, artificial intelligence (AI) is increasingly applied in daily life. When discussing AI, it is inevitable to mention ChatGPT, a language model based on AI technology. Pretrained on extensive language data, ChatGPT can perform various natural language processing tasks, including dialog generation. In addition, similar large language models include the intelligent assistant Kimi launched by Beijing Lunar Tech and the chatbot ERNIE developed by Baidu, among others.</p><p><i>Mycoplasma pneumoniae</i> pneumonia, caused by infection with <i>Mycoplasma pneumoniae</i>, refers to inflammation of the lungs that can affect the bronchi, bronchioles, alveoli, and interstitial tissue. It can occur at any age but is more common in children aged 5 and above, as well as in immunocompromised individuals (such as the elderly, immunodeficient individuals, or patients undergoing immunosuppressive therapy). The course of <i>Mycoplasma pneumoniae</i> pneumonia is generally 1–2 weeks, with a favorable prognosis and no sequelae in most cases. However, a small number of cases can develop into severe conditions, primarily presenting with symptoms of respiratory distress and respiratory failure. These severe cases are often associated with acute respiratory distress syndrome, plastic bronchitis affecting the large airways, diffuse bronchiolitis, and severe pulmonary embolism. In rare instances, severe extrapulmonary complications may be the main manifestations. Given the prevalence of <i>Mycoplasma pneumoniae</i> infection in China, we sought to understand whether ChatGPT could contribute to a better understanding of <i>Mycoplasma pneumoniae</i> pneumonia. We selected 13 questions that are most commonly asked by patients in clinical practice and posed them to ChatGPT-3.5, ChatGPT-4.0, Kimi, and ERNIE. Each question was run five times. Then we invited nine experts with extensive clinical experience and knowledge of Mycoplasma pneumonia to rate the accuracy of the answers. Among them, there were four respiratory specialists and five pediatric specialists, with five from our hospital and four from other hospitals. The scoring criteria were as follows: score = 0: completely incorrect; score &lt; 6: inaccurate; 6 ≤ score &lt; 8: mostly accurate; 8 ≤ score &lt; 10: very accurate; score = 10: completely accurate. The final results were ChatGPT 3.5 8.46 ± 0.80, ChatGPT 4.0 7.05 ± 1.16, Kimi 8.62 ± 0.68, and ERNIE 9.33 ± 0.30. In descending order of accuracy, they were ERNIE, Kimi, ChatGPT 3.5, and ChatGPT 4.0.</p><p>We compared the answers provided by ChatGPT versions 3.5 and 4.0, ERNIE, and Kimi regarding Mycoplasma pneumonia and found that their accuracy ranked from the highest to the lowest as ERNIE, Kimi, ChatGPT 3.5, and ChatGPT 4.0, with ERNIE achieving the highest accuracy.
