Retinal arterial macroaneurysms (RAMs) develop as outpouchings of the arterial wall that is weakened by arteriosclerosis. The traditional treatment of RAMs comprises observation, focal laser photocoagulation, or surgery. Recently, intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs has been announced as an effective therapy for fovea-threatening RAMs and quickly improve visual acuity and central retinal thickness (CRT).In the retrospective series, medical charts and ocular images of 24 patients diagnosed as having RAM between May 2011 and November 2018 in our facility were reviewed to delineate clinical manifestations and visual prognosis in RAM patients receiving different treatment modalities. Twenty-four patients (25 eyes; 11 men and 13 women) were enrolled, and one eye with comorbidity of branch retinal vein occlusion was excluded. The mean age of the patients was 69.00 ± 13.45 years. Fourteen patients (58.33%) had a history of hypertension, and 17 patients (70.83%) were aged &gt;  RAM has been diagnosed. With better final visual acuity, significant visual improvements, and fast reduction of CRT observed in patients with fovea-threatening RAMs receiving anti-VEGF intravitreal injections, intravitreal anti-VEGF was considered an effective therapy for complicated RAM. During the follow-up period, the majority of RAM eyes had good maintenance of visual function even with foveal complications.RATIONALE PMS1 is one of the mismatch repair (MMR) genes with potential crucial roles in carcinogenesis. Very few reports have been identified on germline PMS1 mutations with definite disease phenotype. Here we report a case of hepatocellular carcinoma (HCC) with a novel potential pathogenic germline PMS1 mutation. PATIENT CONCERNS A 46-year-old Chinese male with Hepatitis B infection history presented a single cancerous nodule (10×12×10 mm) at the left lobe of liver. The nodule was considered malignant by type-B ultrasonic and computed tomography (CT) examinations. DIAGNOSIS AND INTERVENTION Liver lobectomy was performed to remove the liver cancerous nodule and postoperative TACE was performed for recurrence prevention. Pathological examination on resected tumor tissue confirmed the diagnosis of HCC. Whole-exome sequencing (WES) identified the c.900delT (p.D300fs) heterozygous germline mutation of PMS1, along with 253 nonsynonymous single nucleotide variations (SNVs), 14 Insertion or deletion mutations (INDELs) and 21 genes with copy number variations (CNVs). Three-dimensional prediction of protein tertiary structure suggested that the conformation of the enzyme active site and the ligand binding site might be changed due to the protein truncation. OUTCOMES The patient was still alive in good condition with no sign of recurrence in 12 months follow-up period. LESSONS The affected pathways in this case were unique from previously reported HCC patients with no PMS1 germline mutations. The novel PMS1 germline mutation may increase cancer risk.

Few reports have described the presence of epithelial-myoepithelial carcinoma in the sinonasal region; hence, the treatment guideline and prognosis remain unclear. PATIENT CONCERNS We reported a case of a 75-year-old woman with complaint of nasal obstruction and frequent epistaxis for 3 years. During the nasal endoscopic examination, a mass in the left nasal cavity originating from the left nasal septum that caused bleeding on touch was observed. DIAGNOSES A diagnosis of epithelial-myoepithelial carcinoma was made based on the features of histopathology and immunohistochemistry of the surgical specimens. The patient was treated by surgical removal of the septal mass using the endonasal endoscopic approach. OUTCOMES In the serial follow-up paranasal sinus imaging and endoscopic inspection, evidence of recurrence was absent for 18 months after surgery. LESSONS This report highlights a case of epithelial-myoepithelial carcinoma originating from a minor salivary gland in the nasal septum, one of the most unusual locations. Diagnosis of epithelial-myoepithelial carcinoma should be made based on the findings of immunohistochemistry of the operative specimen. Clinicians should consider complete surgical resection as the effective treatment of choice.RATIONALE Extracorporeal membrane oxygenation (ECMO) in multiple trauma patients with post-traumatic respiratory failure can be quite challenging because of the need for systemic anticoagulation, which may lead to excessive bleeding. In the last decade, there is a growing body of evidence that veno-venous ECMO (VV-ECMO) is lifesaving in multiple trauma patients with acute respiratory distress syndrome, thanks to technical improvements in ECMO devices. PATIENT CONCERNS We report a case of a 17-year-old multiple trauma patient who was drunken and had confused mentality. DIAGNOSES She was suffered from critical respiratory failure (life-threatening hypoxemia and severe hypercapnia/acidosis lasting for 70 minutes) accompanied by cardiac arrest and trauma-induced coagulopathy during general anesthesia. INTERVENTIONS We decided to start heparin-free VV-ECMO after cardiac arrest considering risk of hemorrhage. OUTCOMES She survived with no neurologic sequelae after immediate treatment with heparin-free VV-ECMO. LESSONS Heparin-free VV-ECMO can be used as a resuscitative therapy in multiple trauma patients with critical respiratory failure accompanied by coagulopathy. Even in cases in which life-threatening hypoxemia and severe hypercapnia/acidosis last for &gt;1 hours during CPR for cardiac arrest, VV-ECMO could be considered a potential lifesaving treatment.To analyze whether a correlation exists between the caries status (Decayed, Missing and Filled Teeth, DMFT Index) of the first permanent molars (FPMs) and that of the full permanent dentition of Mexican adolescents, and to propose its use in large epidemiological studies of dental caries.We conducted a cross-sectional study of 1538 adolescents from 12 to 15 years old. Based on a clinical oral examination, we determined the DMFT Indices of their FPMs (FPM-DMFT) and of their full permanent dentition (comprehensive DMFT Index). We explored each FPM to determine whether it was with or without caries, filled, missing or sealed. For our statistical analysis, we used Fisher exact test and Spearman correlation in Stata software.After examining a total of 6157 FPMs, we found that 56.8% of our sample of adolescents had no caries in their 4 FPMs whereas 4.9% experienced caries in all 4. No significant differences emerged by sex (P &gt; .05); however, by age, the older adolescents experienced greater FPM-DMFT (P  0) was 5.4% (48.
