ObjectiveTo observe and analyze the fundus of pregnancy-induced hypertension syndrome (PIHS) and optical coherence tomography (OCT) characteristics and its correlation with ocular symptoms and degree of the systemic disease. MethodsA total of 132 PIHS patients (264 eyes) received the examinations of corrected visual acuity, slit lamp microscope, direct ophthalmoscope, OCT and fundus color photography after obtaining informed consent in the study. There were 10 cases of gestational hypertension, 29 cases of preeclampsia (mild), 82 cases of pre-eclampsia (severe) and 11 cases of eclampsia. 91 patients (180 eyes) felt blurred vision and visual fatigue. 102 patients were examined at an average gestational age of (37.00±2.14) weeks and 30 patients were examined at an average (10.00±8.22) days postpartum. The ocular fundus was divided into normal fundus and abnormal fundus; the abnormal fundus had 3 stages, including stageⅠ(retinal arterial spasm), stageⅡ(retinal arteriosclerosis) and stageⅢ(retinopathy). If the OCT results seems to be abnormal, these patients were further selected to observe the changes of neurosensory serous retinal detachment, retinal pigment epithelium (RPE) and junction of inner and outer segment of photoreceptor (IS/OS). Kappa test was used to analyze the consistency between fundus performance and OCT results, and that of ocular symptoms with fundus changes and OCT results. Rank correlation test was used to analyze the degree of PIHS and OCT examinations. ResultsThere were 32 eyes with normal fundus (12.12%) and 232 eyes with abnormal fundus (87.88%). The 232 eyes with abnormal fundus were divided into three stages: stageⅠfor 16 eyes (6.90%), stageⅡfor 31 eyes (13.36%) and stageⅢfor 185 eyes (79.74%). 92 of 264 eyes (34.85%) had normal OCT findings, 172 eyes (65.15%) were abnormal, including 94 eyes with serous retinal neurosensory detachment (54.65%), 40 eyes with changes of RPE and IS/OS (23.26%) and 38 eyes with other manifestations (22.09%). Kappa test analysis showed highly consistency between OCT results and ocular symptoms (K=0.728, Po=0.591), and poor consistency between fundus abnormalities and ocular symptoms (K=-0.129, Po=0.879), and between fundus abnormalities and OCT results (K=0.174, Po=0.682). OCT results were positively correlated with the degree of PIHS (C=0.374, χ2=74.011; P=0.000). Conclusions87.88% of PIHS eyes had various degrees of retinal hemorrhage, cotton wool spots, retinal bumps or detachment, optic disc edema and other retinal abnormalities. 65.15% of that showed OCT abnormal results such as neurosensory retinal detachment, cystoid edema, RPE changes etc. The consistency was poor between the OCT results and fundus abnormalities. OCT results are positively correlated with the degree of PIHS.
Objective To explore the clinical characteristics of patients with lymphoma firstly manifested as symptoms in respiratory system. Methods The clinical data of 9 patients with lymphoma were analyzed retrospectively and discussed with literature review. Results There were 7 males and 2 females with an average age of 48.2 years and a median disease course of 20 days. All patients were diagnosed by pathology while specimens were obtained by cervical lymph node biopsies in 2 cases, by CT-guided percutaneous lung biopsies in 2 cases, by bronchoscope mucosal biopsies in 2 cases, by transbronchial needle aspiration biopsies in 1 case, by thoracoscope lung biopsies in 1 case, and by ascites cell block inspection in 1 case. The main symptoms were cough (7/9), expectoration (3/9), fever (3/9) and wheeze (2/9). Chest CT showed tumors (3/9, multiple in 1 case), enlarged mediastinal lymph nodes (6/9), enlarged hilar lymph nodes (3/9), pulmonary consolidation (3/9), pleural effusion (6/9, bilateral in 3 cases), pleural thickening (2/9), pulmonary atelectasis (2/9), patchy shadow (7/9), pericardial effusion (1/9). Laboratory examination demonstrated elevated cancer antigen 125 (CA125) in 7 cases while elevated lactic acid dehydrogenase (LDH) in 4 cases. One patient died during hospitalization in the respiratory department, 1 patient auto-discharged without further treatment, 1 patient died in follow-up period. Five patients remain alive up to now. Conclusions The symptoms of patients with lymphoma are atypical while the chest radiological findings are varied. CA125 and LDH play important role in evaluating disease and predicting prognosis in patients with lymphoma.
