Objective To investigate the clinical manifestation and histopathologic changes of the fungal necrotizing retinochoroiditis. Methods Collecting 7 cases of fungal retinochoroiditis with severe immunodepression and loss of visual acuity.Seven removed eyeballs were stained with HE,PAS and silver methenamine,and observed by light microscopy,and in addition,2 of them examined by electron microscopy.Also fungal cultures of blood and affected tissues were performed. Results The chief clinical macnifestation included ciliary injection of conjunctiva,opaque aqueous fluid and vitreous and diffuse hemorrhage and greyt white opacity with retinal detachment in severe cases.Pathologic changes included hemorrhage in the retina,chorioretinal tissue necrosis,hyphae in the blood vessels,affected tissue and vitreous.Fungal culture of blood was positive in three cases.Culture of affected tissues was positive in all cases. Conclusions Eedogenous fungal infection of choroid and retina may be due to the severe immunodepression of the sufferers and usually causes chorioretinal tissue destruction and blind.

ObjectiveTo discuss the possibility and safety of video-assisted thoracoscope surgery for pulmonary aspergilloma. MethodsWe retrospectively analyzed the clinical data of 39 patients with pulmonary aspergilloma in Beijing Chaoyang Hospital between June 2009 and May 2014. The patients were divided into two groups according to their operation method including a conventional thoracotomy surgery group (open group, n=11) and a video-assisted thoracoscope pneumonectomy group (VATS group, n=28). There were 8 male patients and 3 female patients with age of 29-64 (50.7±9.7) years in the open group. There were 13 male patients and 15 female patients with age of 20-75 (55.4±15.3) years in the VATS group. We compared clinical effectiveness between the two groups. ResultsThe operations of all patients were performed successfully. There were statistical differences between the two groups in the average length of operative time (P=0.001), the loss of intraoperative blood (P=0.005), and the score of pain (P=0.001). There was no statistical difference in lead flow of postoperative chest (P>0.05) and the time of hospitalization (P>0.05). ConclusionVideo-assisted thoracoscope surgery in the treatment of pulmonary aspergilloma could be feasible, safe, and effective based on our study. It is worth of clinical application and popularization．
Objective To investigate diagnosis and treatment strategies of patients with pulmonary tuberculosis （TB） complicated by Aspergillus infection. Methods Clinical data of 38 patients with pulmonary TB complicated by Aspergillus infection who underwent surgical treatment from January 2008 to December 2010 in Chengdu Infectious Disease Hospital were retrospectively analyzed. There were 23 male patients and 15 female patients with their average age of 37.8 （23-59） years. Preoperatively，all the patients received regular anti-TB treatment for more than 2 weeks，and patients with definite Aspergillus infection received anti-Aspergillus therapy for more than 3 days with consultation of infectious disease physicians. After above treatment，26 patients underwent lobectomy，1 patient underwent right pneumonectomy，and 11 patients underwent left pneumonectomy. All the patients were followed up at the outpatient department after discharge. They were evaluated every 2 weeks in the first 3 months，every 1 month after 3 months，and every 6 months after 1 year. During follow-up，they received acid-fast bacillus smear and sputum culture to check Aspergillus，as well as CT chest scan. Results All the patients successfully received surgical resection of the pulmonary lesion without perioperative death or severe complication. Postoperative pathology examination confirmed pulmonary TB with Aspergillosis infection in all the 38 patients，whose basic diseases included TB cavity in 17 patients，TB-destroyed lung in 12 patients，and post-TB bronchiectasis in 9 patients. All the patients were followed up after discharge for 1.5-4.5 years. During follow-up，they received regular anti-TB therapy for adequate duration in addition to antifungal medications such as voriconazole. None of the 38 patients had recurrence of Aspergillus infection or pulmonary TB. One patient had hemoptysis which was controlled after proper treatment during follow-up. Conclusion Missed diagnosis rate of pulmonary TB complicated by Aspergillus infection is high. Surgical resection of the pulmonary lesion and postoperative medication treatment are the most effective treatment strategies for patients with pulmonary TB complicated by Aspergillus infection.
ObjectiveTo analyze the clinical characteristics, prognosis and predisposing factors of coronavirus disease 2019 (COVID-19) associated pulmonary mucormycosis (CAPM), so as to improve people's understanding of the disease.MethodsFrom from September 1, 2021 to July 31, 2024, 11 patients with CAPM who were hospitalized in Beijing Chaoyang Hospital affiliated to Capital Medical University were retrospectively collected, and 22 patients with non-CAPM were included after matching according to the ratio of 1:2. The clinical manifestations, laboratory examinations, imaging features, tracheoscopy, treatment and prognosis of the two groups were analyzed. ResultsThe average age of patients in CAPM group was 59.5 ± 10.6 years, with 81.8% of males; diabetes mellitus (90.9%) was the most common complication. In CAPM group, the median time after the occurrence of mucor after COVID-19 was 13.0 (10.0, 24.0) days. The utilization rate of glucocorticoids in the CAPM group was 63.6% (7/11), which was significantly higher than that in non-CAPM group [13.6% (3/22)], and the difference between the groups was statistically significant (P=0.006). The C-reactive protein level in CAPM group was significantly higher at 93.90 (75.00, 129.00) mg/L than that in non-CAPM group at 26.10 (4.83, 114.03) mg/L, with a statistically significant difference (P=0.040). The CD4+T lymphocyte counts and B lymphocyte counts in CAPM group were 223.00 (66.75, 336.75)/µL and 32.00 (21.75, 55.25)/µL, respectively, which were significantly lower than those in the non-CAPM group 394.00 (206.00, 610.00)/µL and 112.50 (56.00, 159.25)/µL, with statistical differences between the groups (P=0.040, P=0.040). In terms of imaging, the main imaging findings were the involvement of multiple lobes in both groups. 63.6% (7/11) of patients with pulmonary aspergillosis in CAPM group were significantly higher than those(4/22, 18.2%) in non-CAPM group (P=0.017). The incidence of dyspnea in CAPM group was significantly higher than that in non-CAPM group (90.9% vs. 50.0%, 0.027%).ConclusionThe proportion of glucocorticoid use and the proportion of pulmonary aspergillosis in CAPM group are significantly higher, and they are in a more serious state of immunosuppression. Once combined with pulmonary aspergillus , the mortality rate is higher.
