[Brain death: from the transformation of medical concept to the change of medical practice].

The implementation of death determination by clinicians usually involves three steps: learning the concept of death, mastering the skills of death determination, and recording the results of death determination. Each process needs to be changed with the progress of medical science. The transformation of brain death concept is the establishment and formation of the latest cognition of "irreversible brain function", which needs to be completed based on the theoretical learning of recognized standards. The transformation of brain death determination is the learning and mastering of the latest skills of brain death determination, which requires relearning and retraining based on special technologies. The transformation of brain death determination is the habit formation of standardized records of brain death judgement results, which needs to be completed based on the continuous improvement of case quality control. The gradual advancement of the three steps will accelerate the process of determining brain death in China.

[Cardiac amyloidosis: pathological classification and clinical analysis of 48 cases].

Objective: To investigate the histological features and clinical manifestations in different types of cardiac amyloidosis to improve diagnostic accuracy. Methods: The histopathological features and clinical manifestations of 48 patients diagnosed with cardiac amyloidosis by Congo red stain and electron microscopy through endomyocardial biopsy were collected in West China Hospital of Sichuan University from January 2018 to December 2021. Immunohistochemical stains for immunoglobulin light chains (κ and λ) and transthyretin protein were carried out, and a review of literature was made. Results: The patients age ranged from 42 to 79 years (mean 56 years) and the male to female ratio was 1.1 to 1.0. The positive rate of endomyocardial biopsy was 97.9% (47/48), which was significantly higher than that of the abdominal wall fat (7/17). Congo red staining and electron microscopy were positive in 97.9% (47/48) and 93.5% (43/46), respectively. Immunohistochemical stains showed 32 cases (68.1%) were light chain type (AL-CA), including 31 cases of AL-λ type and 1 case of AL-κ type; 9 cases (19.1%) were transthyretin protein type (ATTR-CA); and 6 cases (12.8%) were not classified. There was no significant difference in the deposition pattern of amyloid between different types (P>0.05). Clinical data showed that ATTR-CA patients had less involvement of 2 or more organs and lower N-terminal pro-B-type natriuretic peptide (NT-proBNP) than the other type patients (P<0.05). The left ventricular stroke volume and right ventricular ejection fraction of ATTR-CA patients were better than the other patients (P<0.05). Follow-up data of 45 patients was obtained, and the overall mean survival time was 15.6±2.0 months. Univariate survival analysis showed that ATTR-CA patients had a better prognosis, while cardiac amyloidosis patients with higher cardiac function grade, NT-proBNP >6 000 ng/L, and troponin T >70 ng/L had a worse prognosis (P<0.05). Multivariate survival analysis showed that NT-proBNP and cardiac function grade were independent prognostic factors for cardiac amyloidosis patients. Conclusions: AL-λ is the most common type of cardiac amyloidosis in this group. Congo red staining combined with electron microscopy can significantly improve the diagnosis of cardiac amyloidosis. The clinical manifestations and prognosis of each type are different and can be classified based on immunostaining profile. However, there are still a few cases that cannot be typed; hence mass spectrometry is recommended if feasible.

[Current situation and advancement of brain death determination in China].

China's "Criteria and practical guidance for determination of brain death (BD)" based on medicine was launched eight years ago. After joining the writing and publishing work of "The World Brain Death Project-Determination of Brain Death/Death by Neurologic Criteria", China has accelerated the process of internationalization. For this reason, the author expressed his own opinions on the related work progress and existing problems. (1) Although the criteria of BD in different countries are different due to various national conditions, cultures, religions and laws, we can seek common ground while reserving differences, such as the unification of the minimum criteria and the choice of confirmatory tests. (2) Although there are differences in the executive force of BD evaluation among countries around the world due to whether legislation or not, all walks of life and the public can respect the development of medicine. (3) Although there are still life support and organ donation problems to be solved after the determination of BD, they will be solved one by one through medical practice. In a word, we believe that the specification of BD determination in China will continue to advance orderly and rapidly.

Altered hippocampal functional connectivity in primary Sjögren syndrome: a resting-state fMRI study.

Structural and metabolic abnormalities in the hippocampus have been associated with the pathophysiological mechanism of central nervous system involvement in primary Sjögren syndrome (pSS). Nevertheless, how hippocampal function is altered in pSS remains unknown. The purpose of our study is to investigate the alterations in hippocampal functional connectivity (FC) in pSS by using resting-state functional magnetic resonance imaging (rs-fMRI). Thirty-eight patients with pSS and 38 age- and education level-matched healthy controls (HCs) underwent magnetic resonance imaging examination. Prior to each MRI examination, neuropsychological tests were performed. Left and right hippocampal FCs were analyzed by using seed-based whole-brain correlation and compared between pSS and HCs. Spearman correlation analysis was performed between the z-value of hippocampal FC in brain regions with significant difference between the two groups and neuropsychological tests/clinical data in pSS. Compared with the controls, the patients with pSS showed decreased hippocampal FC between the left hippocampus and the right inferior occipital gray (IOG)/inferior temporal gray (ITG), as well as between the right hippocampus and right IOG/middle occipital gray (MOG), left MOG, and left middle temporal gray. In addition, increased hippocampal FCs were detected between the left hippocampus and left putamen, as well as between the right hippocampus and right cerebellum posterior lobe. Moreover, the visual reproduction score positively correlated with the FC between right hippocampus and right IOG/MOG. The white matter hyperintensity score negatively correlated with the FC between left hippocampus and right IOG/ITG. In conclusion, patients with pSS suffered decreased hippocampal FC mainly sited in the occipital and temporal cortex with right hippocampal laterality. Altered hippocampal FC might be a potential biomarker in detecting brain function changes and guiding neuroprotection in pSS.

[Measurement of uterine volume in patients with endometriosis and its clinical significance].

Objective: To measure the uterine volume by ultrasonic imaging in nullipara patients with endometriosis and analyze its clinical significance. Methods: From July 1st, 2016 to August 1st, 2017, 107 cases of nullipara patients with endometriosis hospitalized in Peking University First Hospital were selected as endometriosis group. Among 107 cases, 59 cases were in proliferative phase of menstrual cycle, 48 cases were in secretory phase; and 10 cases had an abortion history.Totally 101 cases of patients without endometriosis operated for other benign disease during the same period were chosen as the control group. All patients underwent laparoscopic surgery, and the diagnosis was confirmed by pathology. The uterine size was measured by transvaginal or transrectal color Doppler ultrasound, and the uterine volume was calculated according to the known formula. Results: The uterine volume of the endometriosis group [(69±26) cm(3)] was larger than that of the control group [(54±18) cm(3), P<0.01]. In the endometriosis group, the uterine volume of patients with pregnant history [(78±34) cm(3)] was larger than that of patients without pregnant history [(68±25) cm(3)]. The endometrial thickness in endometriosis group was higher than that of the control group [(9.1±3.5) versus (7.8±2.9) mm, P<0.05], and positively correlated with the uterine volume (r=0.39, P<0.05). The hemoglobin in endometriosis group was lower than that in the control group [(124±12) versus (131±10) g/L, P<0.01], and was negatively correlated with the uterine volume in the two groups (r(endometriosis)=-0.12, r(control)=-0.21; both P<0.05).The uterine volume of dysmenorrhea patients in the endometriosis group [(73±28) cm(3)] was greater than that of patients without dysmenorrhea [(62±19) cm(3), P<0.01]; both uterine volumes of patients with and without dysmenorrhea in endometriosis group were larger than those of patients with or without dysmenorrhea in the control group (P<0.05). The degree of dysmenorrhea in endometriosis group was positively correlated with the uterine volume (r=0.20, P=0.042). The uterine volume of stage Ⅳendometriosis patients [(79±30) cm(3)] was greater than that of stage Ⅲ patients in endometriosis group [(58±14) cm(3), P<0.01]. Conclusion: Patients with endometriosis are of increased uterine volume, which may be related to dysmenorrhea, menorrhagia and infertility.

[Introduction of papillomavirus rapid interface for modelling and economics (PRIME) and an example of China's data analysis].

Cervical cancer has become an important disease that jeopardizes women's health, causing hundreds of thousands of new cases annually. Human papillomavirus (HPV) is the leading cause for cervical cancer. Since the world's first HPV vaccine was licensed in 2006, 92 countries around the world have introduced them in national immunization programs. The WHO recommends that scientific economic evaluation should be achieved before the introduction, but this is more difficult for low-and middle-income countries. Therefore, this article introduces a mathematical model recommended by WHO in 2014 to quickly and easily accomplish economic evaluation of HPV vaccine -the PRIME, and take the China's 2018 data published by International Agency for Research on Cancer (IARC) as an example. The evaluation result shows that the introduction of HPV vaccine in Chinese 12-year-old women is cost-effective.

The symptom burden of autonomic dysfunction is positively associated with chronic rhinosinusitis status.

BACKGROUND: Dysregulation of the autonomic system can affect sinonasal physiological function and may exacerbate the symptom burden associated with rhinosinusitis. However, the association between autonomic dysfunction and chronic rhinosinusitis (CRS) has seldom been studied. Here, we investigated the relationship between autonomic dysfunction and CRS. METHODS: Patients with CRS who failed medical treatment were prospectively enrolled. All patients underwent pre-operative examinations and completed questionnaires, including the reflux symptom index (RSI) and the Sino-nasal Outcome Test-22 (SNOT-22). Autonomic dysfunction was scored using the 31-item Composite Autonomic Symptom Score (COMPASS 31), a validated simple instrument used to evaluate dysautonomia. RESULTS: We prospectively enrolled a total of 89 CRS patients, including 37 with polyps (CRSwNP) and 52 without polyps (CRSsNP). The most common dysautonomic symptoms were dry eye, dry mouth, postural dizziness, and a sensation of excessive fullness after meals. Significant positive correlations were evident between COMPASS 31 and SNOT-22 scores in CRSwNP patients. CRS-associated symptoms, including cough, post-nasal drip, sleep, and psychological dysfunction, were correlated with the level of autonomic dysfunction. CONCLUSIONS: We found a positive correlation between the symptom burdens of autonomic dysfunction and CRSwNP. The relationship between autonomic dysfunction and CRS is highly complex; further work is needed.

[The impact of male circumcision on the natural history of genital HPV infection: a prospective cohort study].

Objective: To analyze the correlation between circumcision and incidence and clearance of male genital HPV infection. Methods: From May to July 2014, 18-55 year old men who had sexual behavior history were recruited from the general population in Liuzhou, Guangxi to set up a cohort. Totally, 113 circumcised and 560 uncircumcised men were enrolled and interviewed using a questionnaire (including information on demographic characteristics and sexual behaviors), then they were followed-up with 6-month interval for 2 times. On each visit, specimens of male external genitalia were collected and genotyped for HPV DNA. The differences of incidence and clearance of genital HPV infections between circumcised and uncircumcised men were analyzed by Log-rank test. Cox regression was used to analyze the relationship between circumcision and incidence and clearance of HPV infection. Results: The median age (P(25), P(75)) of circumcised and uncircumcised men were 28 (24, 35) and 32 (24, 31), respectively. The incidences of any HPV infections were 9.1 (95%CI: 2.4-15.7) and 8.4 (95% CI: 5.6-11.2) per 1 000 person-months (χ(2)=0.10, P=0.758), respectively. The clearance of circumcised men [136.3 (95%CI: 70.0-202.7) per 1 000 person-months] was higher than that in uncircumcised men [89.6 (95%CI: 65.9-113.3) per 1 000 person-months] (χ(2)=8.19, P=0.004). In multivariate COX regression analysis, compared with uncircumcised men, circumcised men had higher possibility to clear any HPV infections (HR: 2.41, 95%CI: 1.30-4.46). Compared with men having one sexual partner, people having more than 4 sexual partners had lower possibility to clear any HPV infections (HR: 0.49, 95%CI: 0.25-0.96). Compared with 18-25 years old men, men aged 26-35 years old had higher possibility to clear high-risk HPV infections (HR: 2.14, 95%CI: 1.08-4.23). Conclusion: Circumcised and uncircumcised men had similar incidence of genital HPV infection, whereas, men conducted circumcision and having fewer sexual partners could increase the clearance of genital HPV infections.

[Analysis of clinical characteristics and outcomes of mechanically ventilated patients with anti-N-methyl-D-aspartate receptor encephalitis].

Objective: To explore the clinical characteristics and long-term outcomes of mechanically ventilated patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis. Methods: In this observational study, patients with anti-NMDAR encephalitis were enrolled, who were admitted into Xuanwu Hospital of Capital Medical University from Jan 2012 to Jun 2015.All patients accepted tumor screening, symptomatic therapy, and immunotherapy.Outcomes were assessed by modified Rankin Scale (mRS) after immunotherapy every 6 months, and mRS 0-2 was defined as favorable outcome.The differences of clinical manifestations, auxiliary examinations, and outcomes between mechanical ventilation (MV) group and no MV group were analyzed. Results: Fifty-six patients (mean age 28±12 years, range 12 to 58 years) were enrolled, and 28 were male.MV group included 16 (28.6%) patients.Five female patients were diagnosed with ovarian teratoma.After 6 months, 50 patients (89.3%) had favorable outcomes, mortality was 0.The proportions of patients being female, with ovarian teratoma, conscious disturbance, dysautonomia, accepting plasmapheresis, immunodepressant treatment, admitted into neuro-critical care unit in MV group were significant higher than those in no MV group.The duration of illness prior to MV was 10-73 days (mean 33±19 days). The period of MV was 3-154 days (mean 46±41 days). There was no significant difference in the period of using MV among different outcome groups.After 6-48 months' follow-up, 6 patients (10.7%) relapsed, with 1 patient in MV group (1/16, 6.3%), 5 patients in no MV group (5/40, 12.5%). The relapses and long-term outcomes were not significant different between MV group and no MV group. Conclusions: The condition of mechanically ventilated patients with Anti-NMDAR encephalitis is severe, and the treatment is difficult. However, after active combined immunotherapy and life support, majority of these patients could get good long-term outcomes.

[Clinical efficacy of acute intraoperative encephalocele prevention strategy for severe traumatic brain injury].

Objective: To explore the clinical efficacy of prevention strategy for acute intraoperative encephalocele of patients with severe traumatic brain injury (sTBI). Methods: A total of 173 patients with sTBI, who treated in Emergency Neurosurgery Department of Shandong University Qilu Hospital from January, 2011 to September, 2015 were collected and divided into research group and control group, according to their therapeutic strategy.The clinical data during hospitalization and prognosis 1 year after injury was analyzed retrospectively to clarify the effect of acute encephalocele prevention strategy. Results: There were no statistically significant differences in sex, age, preoperative Glasgow coma scale score and imaging type of lesion between patients from the two groups.The highest intraoperative intracranial pressure in the research group and control group were (35.71±4.13) mmHg and(34.85±3.81) mmHg, respectively.The acute encephalocele incidence of the research group (7 cases, 6.5%) was significantly lower than that of the control group (13 cases, 19.7%) (P<0.01). Subgroup analysis showed that the incidence of acute encephalocele in patients with only unilateral lesions was low (1.3%), while higher (19.4%) in patients with both unilateral lesions and other secondary lesions or diffuse brain swelling.The prognosis of the patients was evaluated by Glasgow Outcome Scale according to the follow-up 1 year after injury, and it was suggested that the percentage of patients with good outcome in the research group (62 cases, 57.9%) was remarkably higher than that in the control group (26 cases, 39.4%) (P=0.018). Conclusions: For sTBI patients with high risk of acute encephalocele, prevention strategy was found to be able to retard the progression of delayed hematoma and diffuse brain swelling, prevent the acute encephalocele during operation, and then significantly improve the prognosis.

Label-free aptasensor for adenosine deaminase sensing based on fluorescence turn-on.

A label-free and fluorescence turn-on aptamer biosensor has been developed for the detection of adenosine deaminase (ADA) activity with simplicity and selectivity. Adenosine aptamer will form a tight stem-loop structure upon binding with adenosine. In the absence of ADA, only a small quantity of picagreen intercalates into the stem section of aptamer, resulting in a low fluorescence of picagreen when excited at 490 nm. Interestingly, after the addition of ADA, adenosine is hydrolyzed to inosine, and the released aptamer forms double-stranded DNA (dsDNA) with its complementary single-stranded DNAc, followed by the intercalation of picagreen to dsDNA. When the solution is excited, picagreen emits strong green fluorescence. The increased fluorescence intensity of picagreen is dependent on the concentration of ADA. The detection limit of the ADA is determined to be 2 U L(-1), which is lower than ADA cutoff value (4 U L(-1)) in the clinical requirement and more sensitive than most of the reported methods. Compared to other previous ADA sensors, the assay is not only label-free but also a turn-on signal, and possesses properties of lower cost and simpler detection system. Furthermore, this label-free strategy is also applicable to the assay of other enzymes and screening of corresponding inhibitors.

[The effect of Ba Duan Jin on the balance of community-dwelling older adults: a cluster randomized control trial].

Objective: To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults. Methods: A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test. Results: A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95%CI: 2.23-3.88) points (P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95%CI: 4.03-5.37) points (P<0.001). Ba Duan Jin showed significant improvement (P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions: This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

[Clinical effects of retrograde anterolateral thigh flaps in repairing anterior knee joint wounds under the concept of precise flap surgery].

Objective: To introduce the methods of retrograde anterolateral thigh flaps in repairing anterior knee joint wounds under the concept of precise flap surgery and to explore the clinical effects. Methods: A retrospective observational study was conducted. From August 2014 to March 2022, 7 patients with anterior knee joint wounds were treated with retrograde anterolateral thigh flap under the guidance of the concept of precise flap surgery in the 920th Hospital of Joint Logistic Support Force of PLA. Among them, 6 were males and 1 was female, aged 36 to 66 years. The sizes of wounds were 7 cm×5 cm to 15 cm×11 cm after debridement. All the patients were performed with computed tomography angiography (CTA), the donor and recipient sites were evaluated according to the precise flap surgery method, and the optimal pedicle, perforator, and pivot of flaps were chosen. The flap sizes were 10 cm×6 cm to 20 cm×9 cm, and all the donor sites of flaps were sutured directly. The consistency of the intraoperative exploration with preoperative CTA was observed. The flap survival and occurrence of complications were observed after surgery. The color, appearance, texture, and occurrence of complications were followed up. At the last follow-up, the blood supply of flaps was evaluated using the blood circulation evaluation indicators of Chinese Medical Association Hand Surgery Branch's trial criteria for digital replantation function evaluation, and the function of knee joint was evaluated using knee joint scoring system of hospital for special surgery. Results: The flap condition of the intraoperative exploration was completely consistent with that of preoperative CTA. The flaps survived completely after surgery in 6 patients, while necrosis at the edge of the flap occurred in 1 patient, which healed after dressing change. All the flaps were hyperperfused after surgery, and the color of the flaps gradually became normal after 1 week. Follow-up of 7 to 44 months showed that the color, appearance, and texture were well in all the patients, while local osteomyelitis at the proximal tibia occurred in 1 patient. At the last follow-up, all the 7 patients had excellent blood circulation; the function score of knee joint was 69 to 91, which was evaluated as excellent in 3 cases, good in 3 cases, and fair in 1 case. Conclusions: The retrograde anterolateral thigh flap has large variations, and the application of precise flap surgery method can accurately understand the variations before surgery, guide the design and cutting of the flaps, thus achieving precise repair of anterior knee joint wounds, with good repair outcome.

The association between UGT1A1 polymorphisms and treatment toxicities of liposomal irinotecan.

BACKGROUND: Initial dose adjustment is recommended for patients with known UGT1A1∗28 homozygosity for both conventional irinotecan and liposomal irinotecan (nal-IRI). A recent population pharmacokinetic (PK) study showed that Asian patients had a lower prevalence of UGT1A1∗28 homozygosity but a significantly higher maximum blood concentration of SN-38 (SN-38 Cmax) and a higher incidence of grade ≥3 neutropenia after nal-IRI administration than Caucasian patients. The current study investigated the association of UGT1A1 polymorphisms, including the Asian prevalent UGT1A1∗6, PK and toxicities of nal-IRI-based therapy in the Asian population. PATIENTS AND METHODS: A total of 162 patients with nal-IRI-based therapy and available UGT1A1∗6 and UGT1A1∗28 genotyping were included, with 82 Asian patients from six previous phase I or II studies of nal-IRI (cohort 1) and another 80 patients with nal-IRI + 5-fluorouracil/leucovorin every 2 weeks as real-world practice in a single institute in Taiwan (cohort 2). RESULTS: The frequency of UGT1A1∗6 or UGT1A1∗28 homozygosity/compound heterozygosity was 9.3%, with UGT1A1∗6/∗6 in 2.5%, UGT1A1∗28/∗28 in 1.9% and UGT1A1∗6/∗28 in 4.9%. Among the 53 patients in cohort 1 with available PK data, all 7 patients with homozygosity/compound heterozygosity harbored UGT1A1∗6 and had a significantly higher level of median dose-normalized area under the concentration-time curve (AUC) and Cmax of SN-38 than those with single heterozygosity/wild type. Of the entire study population, the incidence of grade ≥3 neutropenia and diarrhea was significantly higher in patients with homozygosity/compound heterozygosity than in those with single heterozygosity/wild type, 73.3% versus 38.1% (P = 0.012, Fisher's exact test) and 33.3% versus 9.5% (P = 0.018, Fisher's exact test), respectively. CONCLUSION: The results suggest that the recommendation of a lower starting dose of nal-IRI for patients with UGT1A1∗28 homozygosity should be extended to include patients with UGT1A1∗6 homozygosity/compound heterozygosity.

First Report of Leaf Disease on Cinnamomum subavenium Caused by Colletotrichum fioriniae in China.

Cinnamomum subavenium Miq. (Lauraceae) is a subtropical arbor plant widely distributed in southwest China. It has a long history of cultivation and has been widely used in traditional Chinese medicine, food flavors, and industrial materials. In August 2010, a serious leaf disease was observed on wild Cinnamomum subavenium growing in Gutianshan Nature Reserve, Zhejiang, China. Lesions were approximately 1.0 cm in diameter and the margin of the lesions was light to dark brown and the middle was gray to pale yellowish. Necrotic lesions were surface disinfected with 1% sodium hypochlorite for 1 min and 70% ethanol for 3 min, and isolations were made from lesion edges onto potato dextrose agar (PDA). Three plants were tested and a fungus was consistently isolated from lesions. Colonies of this fungus on PDA were at first gray becoming pinkish gray with age, with salmon pink conidial masses, and the reverse of the colony was pink. The growth rate was 10.82 to 11.95 mm per day (average = 11.58 ± 0.25, n = 6) on PDA at 25°C. Conidia were oblong or cylindrical with acute ends, occasionally guttulate, hyaline, 7.5 to 14.5 × 2.5 to 4.3 µm (average = 11.25 ± 0.5 × 3.4 ± 0.4, n = 30). These characteristics matched the description of Colletotrichum fioriniae (Marcelino & Gouli) R.G. Shivas & Y.P. Tan (2). DNA was extracted from one isolate and the rDNA-internal transcribed spacer (ITS) region was amplified and sequenced using primers ITS1 and ITS4 (1). The ITS sequence of the isolate (GenBank Accession No. JN208890) shared 100% identity to the holotype of C. fioriniae (Accession No. EF464594). The pathogenicity of C. fioriniae on Cinnamomum subavenium was confirmed through inoculation. Three freshly harvested, healthy leaves were washed under running tap water, immersed in 5% sodium hypochlorite for 3 min and 70% ethanol for 1 min, rinsed three times in sterilized water, and finally dried with sterilized tissue paper. Plant leaves were inoculated with a concentration of 2.5 × 106 spores/ml. Sterilized water was used for controls. All the leaves inoculated with C. fioriniae were symptomatic with round to elliptical lesions with a brown margin 14 days postinoculation. The fungus, reisolated from symptomatic leaf tissue, had the same morphological and cultural characteristics of C. fioriniae. Although C. gloeosporioides has been reported from several species in the genus Cinnamomum ( http://nt.ars-grin.gov/fungaldatabases/ ), to our knowledge, this is the first report of leaf disease on Cinnamomum subavenium caused by a Colletotrichum species.
