Purpose:To assess the retinal features in eyes with postoperative metamorphopsia (POM) following rhegmatogenous retinal detachment (RRD) repair using multimodal imaging (MMI).Methods:In this cross-sectional; case-control study, patients after successful RRD repair following 25-gauge vitrectomy, clear vitreous cavity, and corrected distance visual acuity (CDVA)>20/200 were categorized using Amsler chart: cases with POM and controls without POM. MMI was performed on swept-source platform (Triton, Topcon Inc) and the confocal scanning laser ophthalmoscope system (Spectralis HRA, Heidelberg). The measures assessed were CDVA, morphological features on optical coherence tomography, autofluorescence, and multicolor imaging (MCI).Results:Thirty-nine eyes were included in each group. Cases had greater number of eyes with total RRD (P = 0.029) preoperatively; abnormal foveal contour (P = 0.036), ellipsoid zone (EZ) disruption (P < 0.001) and poorer postoperative CDVA (P = 0.046) as compared to controls. Outer retinal folds and retinal shift (unintentional translocation of retina after reattachment surgery for RRD) did not differ significantly between the groups (P = 0.48 and 0.35, respectively). On MCI, the distribution of detected ERM was similar between the groups (P = 0.25). Postoperative CDVA was significantly worse in eyes with POM.Conclusion:POM is affected by extent of RRD, postoperative foveal contour, and EZ status but not by retinal shift. 相似文献

A prospective study of blood glucose level at the time of admission was done on 532 cases of severe and complicated malaria admitted in classified malaria ward at PBM Hospital, Bikaner. Eleven patients had blood glucose level < 40 mg% (< 2.2 mmol/L) and all were unconscious with diagnosis of cerebral malaria. Four patients became conscious with i.v. infusion of 25% dextrose only without receiving any specific antimalarial treatment. Recognition of these patients of "falciparum malaria with hypoglycaemia" by blood glucose estimation at the time of admission can significantly affect the ultimate outcome. The mortality trend was more in patients having blood glucose level < 40 mg% (< 2.2 mmol/L) in comparison to group of patients having blood glucose level between 41 to 60 mg% (2.2 to 3.3 mmol/L) and was least in those having blood glucose level > 60 mg% (> 3.3 mmol/L). 相似文献

This report deals with a young girl with Duane's retraction syndrome who also had left facial hemiatrophy (Parry-Romberg syndrome). Report of such an association is probably first of its type to be documented in literature. 相似文献

Like most bacteria, Leptospira spp. requires iron for growth. However, they face conditions of iron limitation due to the low solubility of the ferric iron and additionally due to the observation that most of the available iron is held as protein-bound iron by the mammalian host. Our experimental observations with pathogenic Leptospira showed that they do not elaborate siderophores upon iron limitation. In Leptospira interrogans serovar Lai, we demonstrated direct acquisition of iron via an iron-regulated hemin-binding protein HbpA. PCR analysis and Southern hybridization studies revealed that the hbpA gene was conserved in the serovars belonging to L. interrogans species and was absent in the non-pathogenic Leptospira biflexa serovar Patoc and Leptospira meyeri serovar Ranarum. Here, we extended the PCR-based detection of the hbpA gene to clinical isolates and demonstrated the hbpA amplicon in all the serovars belonging to L. interrogans species from a total collection of 91 clinical isolates obtained from different geographical regions. In addition, we detected anti-HbpA antibodies in the serum of patients with leptospirosis. PCR-based detection of hbpA in clinical isolates of serovars and the in vivo expression of HbpA reflects the diagnostic potential of this antigen. 相似文献

Although acute appendicitis is one of the most common surgical emergencies worldwide, timely accurate diagnosis is always difficult for a surgeon even after availability of recent diagnostic tools. Our study is to determine validation of RIPASA score in diagnosis of acute appendicitis and histopathological correlation. A prospective study of 200 patients presented to emergency or surgical opd with right iliac fossa pain and suspected to have acute appendicitis were included in our study. RIPASA score calculated but appendectomy done on the basis of clinical assessment and hospital protocol and histopathological correlation done with a score. A score of 7.5 is cut off threshold, results compared with previous studies. In our study of 200 patients, M:F ratio of 1.56:1. Sensitivity of the RIPASA score was 95.89℅ with specificity 75.92% and diagnostic accuracy of 90.5%, expected and observed rate of negative appendectomy were 8.5 and 12.35%, respectively. So there is net reduction in negative appendectomy rate by 3.85%. Data analysis done with Statistical Package for Social Science (SPSS) version 21.0. RIPASA score at a cutoff value of 7.5 is easier, cheap, and better diagnostic tool in equivocal case of right iliac fossa pain in Indian scenario of limited availability of recent diagnostic tool in remote areas and affordability of these tool in the available set up, simultaneously, it also helps to reduce negative appendectomy rates. 相似文献

Falciparum malaria in pregnancy is a significant health problem in India. Pregnant women constitute an important high risk group for malaria infection which may cause abortion, still births, intra uterine growth retardation (IUGR), and pre-mature labour. Two hundred eighty-eight admitted female patients of falciparum malaria were included in the study out of which 45 were pregnant. The mortality rate was highly significant in pregnant females (37.77%) in comparison to non-pregnant females (14.81%); (p < 0.001). The incidence of various pernicious syndromes including cerebral malaria, severe anaemia (Hb < 5 g%) hepatic and renal failure were more in pregnant females in comparison to non-pregnant females. The incidence of infection was higher among primigravida and second gravida 30/45 (66.66%) as compared to multigravida 15/45 (33.33%) and the greater incidence of infection was seen during 14-28 wk of gestation 23/45 (51.11%). Pregnancy related complications in the form of preterm live birth (20%). Intra uterine death (IUD 31.11%), still births (13.33%) and abortions (11.11%) were more pronounced in primiparous women as compared to multiparous. Weight of placenta in majority of patients ranged between 200-400 g (22/31; 70.96%). Normal pregnancy continued in only 11 out of 45 pregnant females, out of which seven had low birth weight body (63.63%). As the pregnancy is associated with increased incidence and adverse outcome of falciparum malaria infection, chemoprophylaxis should be made an integral part of antenatal care along with antianaemic therapy to reduce the risk of serious maternal and fetal complications. 相似文献
