Pulmonary contusion mimicking COVID-19: A case report.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a major public health emergency with obvious characteristics of human-to-human transmission, and there are infective asymptomatic carriers. Early identification and proper management of patients with COVID-19 are important. Features in chest computed tomography (CT) can facilitate identifying newly infected individuals. However, CT findings of some lung contusions are similar to those of COVID-19, as shown in the present case. CASE SUMMARY: A 46-year-old woman was admitted to hospital for backache and foot pain caused by a fall injury 1 d before hospitalization. She was suspected of having COVID-19, since there was a confirmed COVID-19 case near her residence. But she had no fever, cough, chest tightness, difficult breathing, nausea, vomiting, or diarrhea, etc. On physical examination, the lower posterior chest of both sides showed dullness on percussion and moist rales at the end of inspiration on auscultation. The white blood cell count and lymphocyte count were 10.88 × 109/L and 1.04 × 109/L, respectively. CT performed on February 7, 2020 revealed that both lungs were scattered with patchy ground-glass opacity. The patient was diagnosed with pulmonary contusion with thoracic spinal fracture (T12), calcaneal fracture, and pelvic fracture. On day 9 after conservative treatment, her condition was alleviated. On review of the chest CT, the previous shadows were significantly reduced. CONCLUSION: Differential diagnosis of lung contusion and COVID-19 must be emphasized. Both conditions require effective prompt actions, especially COVID-19.

Genetic association between IL-27 rs153109 polymorphism and cancer risk in Chinese population: a meta-analysis.

IL-27 plays an important role in anti-cancer activity. The -964A/G polymorphism in IL-27 gene has been implicated in susceptibility to cancer, but the results were conflicting. The aim of this study was to assess the association between this polymorphism and cancer risk. Pubmed and Wanfang database were searched for all publications concerning IL-27 -964A/G polymorphism and cancer risk. Odds ratio (OR) and 95% confidence interval (CI) were used to assess the strength of association. Statistical analysis was performed using Stata 11.0 software. A total of eight case-control studies including 2044 cancer cases and 2197 controls were identified. Overall, significant association between IL-27 -964A/G polymorphism and cancer risk was observed (GG versus AA: OR = 1.26, 95% CI = 1.03-1.52; GG versus AG + AA: OR = 1.20, 95% CI = 1.00-1.44). In subgroup analysis based on cancer type, significant association was found in colorectal cancer (GG versus AA: OR = 1.55, 95% CI = 1.07-2.27; AG versus AA: OR = 1.31, 95% CI = 1.02-1.67). The current meta-analysis suggests that IL-27 -964A/G polymorphism might enhance cancer risk. However, large-scale and well-designed studies are still needed to confirm the result of our meta-analysis. The association of IL-27 polymorphism with colorectal cancer may provide insight for future therapies.

Herbal medicine for hospitalized patients with severe depressive episode: a retrospective controlled study.

Herbal medicine is increasingly used in depressed patients. The purpose of this retrospective controlled study was to evaluate the efficacy and safety of herbal medicine treatment of severe depressive episode. A total of 146 severely depressed subjects were selected from patients who were admitted to the Department of Psychosomatics of Tongde Hospital at Hangzhou, China between 1st September 2009 and 30th November 2013. While all were medicated with psychotropic drugs, 78 received additional individualized herbal medicine. The severity of depressive symptoms was measured using 24-item Hamilton Rating Scale for Depression (HAMD-24) at admission and thereafter once weekly during hospital stay. The proportion of patients achieving clinical response and remission and incidence of adverse events were compared. The two groups had similar average length of hospital stay for approximately 28 days and were not different in the use of psychotropic medications. Survival analysis revealed that patients with herbal medicine had significantly higher chance of achieving clinical response [relative risk (RR)=2.179, P<0.001] and remission (RR=5.866, P<0.001) compared to those without herbal medicine. Patients with herbal medicine experienced remarkably fewer incidences of physical tiredness, headache, palpitation, dry mouth and constipation, but had a significantly higher incidence of digestive discomfort compared to patients without herbal medicine. These results indicate that additional treatment with individualized herbal medicine enhances antidepressant response and reduces certain side effects associated with psychotropic medications. Herbal medicine is an effective and relatively safe therapy for severe depressive episode (Trial Registration: ChiCTR-OCH-13003864).

[Selective serotonin reuptake inhibitor is more likely to induce sexual dysfunction than mirtazapine in treating depression].

OBJECTIVE: To compare the incidences of sexual dysfunction induced by mirtazapine and SSRI in the treatment of patients with depression. METHODS: Using key-word retrieval from the compact disks of the Chinese biological medicine (CBM) data base, we analyzed the rates of sexual dysfunction from the published clinical control trials on depression treated with mirtazapine and SSRI by applying the fixed effects model (FEM) of evidence-based medicine (EBM). RESULTS: Among 1108 cases in 14 studies, there were 5 cases of mirtazapine-induced and 106 cases of SSRI-induced sexual dysfunction, accounting for 0.90% and 19.2% respectively, OR = 0.07 (95% CI: 0.04-0.14), Z = 8.03, P < 0.01. CONCLUSION: SSRI is far more likely to induce sexual dysfunction than mirtazapine in the treatment of depression.
