  • Classification of macular retinoschisis in pathological myopic eyes by optical coherence tomography and its clinical applications

    Pathological myopic macular retinoschisis can be classified into 4 types based on optical coherence tomography (OCT) images: outer layer retinoschisis, outer + middle layer retinoschisis, outer + inner layer retinoschisis and multilayer retinoschisis. Currently vitrectomy is the major option to treat this condition as it can remove the posterior vitreous cortex completely and peel the internal limiting membrane (ILM) around the posterior vessels arch. Vitrectomy benefits the visual function significantly for outer layer retinoschisis with foveal detachment, but has no or very little effects on multilayer retinoschisis. The appropriate starting site for removal of posterior cortex and ILM should be the site without inner layer retinoschisis. The knowledge and understanding of the OCT classification of pathological myopic macular retinoschisis is important for us to chose correct operation methods and determine the prognosis after treatment.

  • Pneumonia Caused by Staphylococcus intermedius: A Case Report and Literature Review

    ObjectiveTo summarize the clinical features of infection with Staphylococcus intermedius and its differential diagnosis. MethodsA clinical case of Staphylococcus intermedius infection was analyzed and Chinese literatures about Staphylococcus intermedius infection were reviewed.The literatures were derived from domestic medical journals in CNKI Digital Library and Wanfang Databases from 1998 to 2015. ResultsThe patient was a 35-year-old male.The chief complaints were cough and sputum associated with fever for three days.Chest CT scan showed cuneate and flocculent shadow with high density and unclear margin in the posterior segment of the right upper lobe and aerated bronchus sign was seen.Fuzzy shadow under the pleural was observed in the right lower lobe; On the right side of the chest, a little curved liquid density was seen.Sputum culture in Columbia blood agar plate and chocolate agar plate was done and Staphylococcus intermedius was identified.The final diagnosis of this patient was pneumonia caused by Staphylococcus intermedius.Fleroxacin 0.4 g per day was given by intravenous drip.Two weeks later, chest CT scan showed cuneate and flocculent shadow in the right upper lobe decreased obviously.Fuzzy shadow under the pleural the right lower lobe and pleural effusion on the right side of the chest disappeared.Four cases with Staphylococcus intermedius infection were reported and 3 were children.Two patients had open wound with infection.The involved organs included brain, joints, lungs, and one patient developed septicemia.Staphylococcus intermedius was identified from blood, sputum, cerebrospinal fluid, and pus from the open wound.By treatment with sensitive antibiotics three patients were cured but one patient with meningoencephalitis died of circulatory failure. ConclusionsStaphylococcus intermedius infection can occur in many organs and its clinical manifestations are dependent on the infected location.Specimen culture for pathogen is necessary and blood, sputum, cerebrospinal fluid, and pus from the open wound are optional candidates.Cultivation of Staphylococcus intermedius is similar to that of Staphylococcus aureus and should be differentiated carefully.Early treatment with high sensitive antibiotics is effective with good prognosis.

  • Clinical manifestations and prognosis of choroidal tuberculoma

    ObjectiveTo investigate the clinical features and prognosis of patients with choroidal tuberculoma. MethodsA retrospective and observational study. From 2011 to 2022, 15 patients (16 eyes) with choroidal tuberculoma diagnosed and treated in Department of Ophthalmology, Shanghai Eye & ENT Hospital of Fudan University were included. The patients underwent examinations including best corrected visual acuity (BCVA), fundus color photography, optical coherence tomography (OCT), fluorescein fundus angiography (FFA), and indocyanine green angiography (ICGA). Chest CT examination, purified protein derivative test and interferon-γ release test were also performed. BCVA was performed using the Snellen visual acuity chart, which was converted to Logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. All the patients received antitubercular therapy and the duration was 12-15 months. Thirteen patients were combined with oral corticosteroids. The average follow-up time was 36 months. Rank sum test was used to compare logMAR BCVA before and after treatment. ResultsAmong the 15 patients, 5 were male and 10 were female; 1 case was bilateral involvement; 7 patients had a strong positive tuberculin skin test; 8 patients had a positive interferon-γ release assay. Six patients had pulmonary tuberculosis. One patient had peritoneal tuberculosis. Lesions were located in the posterior pole in 12 eyes, 1 eye with papillary tuberculoma. Peripheral lesions were found in 4 eyes. There were 9 eyes each with anterior segment inflammation or vitreous inflammation; 7 eyes were with exudative retinal detachment. OCT examination revealed a hyporeflective thickening of the choroidal stroma, the corresponding elevation of the retina, and often accompanied by subretinal fluid. FFA revealed hyperfluorescence of the mass and fluorescence accumulation with subretinal fluid at the late stage. ICGA revealed hypofuorescence of the lesion. The lesions subsided after treatment, and there was no recurrence during follow-up period. Cataract surgery was performed in 4 eyes due to complicated cataract. One eye undergone vitrectomy due to secondary rhegmatogenous retinal detachment. Anti-vascular endothelial growth factor therapy was performed in 1 eye due to secondary choroidal neovascularization. Ocular wall perforation occurred in 1 eye, and the condition was stable after treatment. Before treatment, the average logMAR BCVA was 1.02±0.57, which improved to 0.31±0.35 after treatment. The difference between the mean logMAR BCVA before and after treatment was statistically significant (P<0.05). ConclusionsCombination of medical history, clinical manifestations, laboratory tests, and imaging can assist in the diagnosis of choroidal tuberculoma. The main manifestations are subretinal yellowish-white lesions in posterior pole. Standardized anti-tuberculosis therapy can effectively improve the prognosis of vision.

  • Long-term efficacy of laparoscopic cholecystectomy for gallbladder cancer

    ObjectiveTo investigate the long-term efficacy of laparoscopic cholecystectomy (LC) for gallbladder cancer.MethodThe clinical data of 52 patients with gallbladder cancer only underwent LC from January 1998 to December 2018 in the Peking Union Medical College Hospital were analyzed retrospectively.ResultsFifty-two patients met the inclusion criteria were included, including 23 males and 29 females. The age was (67±12) years. Fifty-two patients were treated with LC because of gallbladder occupying or gallstone. Twenty-three patients were diagnosed as incidental gallbladder cancer after the surgery, while 29 patients were diagnosed as the gallbladder cancer before or during the operation. Eleven patients with T1a lesions received the close follow-up, the other 41 patients refused the radical operation due to the advanced age, severe underlying diseases or their own preferences. Five cases of postoperative complications were observed. All patients were followed-up for (40.2±33.8) months, 21 patients survived and 31 died. The dead patients had an older age, longer hospital stays, and later T stage (P<0.050) as compared with the living patients. The patients with T1a lesions had significantly longer survival time than those with T1b and above (113.5 months versus 39.6 months, P<0.001).ConclusionsLC is a radical operation in T1a lesions. At the same time, it can meet the requirements of postoperative life quality for some special patients due to its safety and low postoperative complication rate.

  • Analysis of therapeutic effect of T2a gallbladder cancer whether combined with liver resection or not

    ObjectiveTo investigate the effect of combined or non-combined liver resection for T2a gallbladder cancer. MethodsAccording to the established inclusion and exclusion criteria, the patients with T2a gallbladder cancer admitted to Peking Union Medical College Hospital from January 2016 to December 2021 were retrospectively collected, then were assigned into combined with liver resection group and non-combined with liver resection group. The general characteristics, perioperative information, and prognosis of the two groups were compared. ResultsA total of 58 patients were enrolled in this study, including 23 males and 35 females; aged (64.8±11.1) years. There were 43 cases in the combined with liver resection group and 15 cases in the non-combined with liver resection group. There were no statistic differences in the demographic data, lifestyle, onset symptoms, preoperative combined diseases, and preoperative tumor markers between the two groups (P>0.05). Compared with the combined with liver resection group, the proportion of patients received bile duct resection was higher (P=0.013) and the operation time was shorter (P=0.045) in the non-combined with liver resection group. There were no statistic differences in the other perioperative informations between the two groups (P>0.05). A total of 12 patients had postoperative complications, including 3 cases of grade Ⅰ, 8 cases of grade Ⅱ, and 1 case of grade Ⅲa by Clavien-Dindo classification. All patients improved after treatment and were discharged smoothly. No patient was readmitted within 30 d after discharge. All 58 patients were followed up with a median follow up time of 29 months. During the follow-up period, there were 47 cases (81.0%) of tumor-free survival, 2 cases (3.4%) of survival with tumor, and 9 cases (15.5%) of death. There were no statistic differences in the overall survival and disease-free survival between the two groups by log-rank test (χ2=3.418, P=0.064; χ2=1.543, P=0.214). ConclusionFromthe results of this study, for T2a gallbladder cancer, liver resection would not result in increased complications or longer hospital stay, but don’t obviously improve prognosis.

  • Optical coherence tomography features of Best vitelliform macular dystrophy at different stages

    Objective To observe the optical coherence tomography (OCT) features of Best vitelliform macular dystrophy (BVMD) at different stages.Methods Twenty-eight BVMD patients (56 eyes) were enrolled in this study. All the patients were examined for visual acuity, slit-lamp microscopy, direct ophthalmoscope, fundus photography, electrooculogram, fundus fluorescein angiography (FFA) and OCT. Fifty-six eyes were classified into stage 0 (eight eyes)、Ⅰ (two eyes)、Ⅱ(10 eyes)、Ⅱa (12 eyes)、Ⅲ (six eyes) 、Ⅳa (six eyes)、Ⅳb (five eyes) and Ⅳc (seven eyes) accordingly. The OCT features of BVMD at different stages were observed.Results The OCT results showed that the macular area was normal in eyes of stage 0; disturbance of retinal pigment epithelium (RPE) and subretinal hyporeflective area were found in eyes of stage I; the location of the yellowish material between RPE and the inner segment and outer segment (IS/OS) with normal appearance in RPE and IS/OS interface were found in eyes of stage Ⅱ. In all the other progressing stages from Ⅱa、Ⅲ and Ⅳ, the vitelliform material appeared as a thicker highly reflective lesion located between the outer nuclear layer and RPE layer, usually accompanied by optical hyporeflective lesion. Images of stage Ⅳc were in similar appearance besides edema of retina. OCT images of Ⅳb stage were demonstrated atrophy of retinal layer and IS/OS loss with fibrosis. Conclusions OCT demonstrated the location of the yellowish material between RPE and IS/OS. Optical hyporeflective lesion between the outer nuclear layer and RPE layer accompanied thicker highly reflected lesion might be the characteristic image in stages II a to IV of BVMD.
