Abstract:
Abstract Purpose Prospective, randomised, open-label, comparative study to evaluate efficacy of trehalose/sodium hyaluronate eye drops for post-operative discomfort and tear film stability in patients undergoing cataract surgery. Methods Patients with healthy ocular surface, subclinical, or mild dry eye were enrolled. Tear breakup time (TBUT), Schirmer test, dry eye symptoms, corneal fluorescein staining (CFS), and ocular surface disease (OSDI) evaluation were performed pre-operatively and at two and four weeks after surgery. Patients were assigned to receive trehalose/sodium hyaluronate eye drops b.i.d (Group A), or 0.9% unpreserved sodium chloride eye drops b.i.d for 4 weeks (Group B). Results One hundred and thirty-five patients were randomised, 66 patients in Group A (73.2 ± 4.5 years) and 69 patients in Group B (74.3 ± 3.8 years), 60.8% females. Fifteen patients (8 Group A) were lost at follow-up. Pre-operatively, no between-group differences were observed, and TBUT increased in Group A between the pre-operative and 2 and 4 week evaluations and was higher in group A than in Group B at 4 weeks. Schirmer test and CFS showed an improvement only in Group A four weeks post-operatively. In Group A an improvement was observed after two and four weeks in foreign body and puncture sensation, whilst a difference in blinking discomfort was observed after four weeks. In Group B we observed an improvement in puncture sensation two and four weeks after surgery. Mean OSDI scores differences between the two groups were significant at four weeks. Conclusions Trehalose/sodium hyaluronate eye drops were effective in reducing signs and symptoms of dry eye and improving tear film stabilityKeywords:

It is generally easy to diagnose and treat patients with thyroid diseases, though there has been considerable uncertainty over whether or not to treat patients with subclinical disease.An overview of clinical symptoms and complications related to subclinical thyroid disease is presented on the basis of relevant literature.Patients with subclinical hypothyreosis (elevated TSH level and normal free T4) may benefit from treatment with thyroxine in relation to well-being, serum lipid levels, and possibly also blood pressure. Patients with subclinical hyperthyreosis (suppressed TSH level and normal free T4) have an increased risk of developing atrial fibrillation and possibly also dementia.Subclinical thyroid disease is usually progressive. If a transient condition is ruled out, proper treatment should not be delayed.

Background Symptoms of subclinical hypothyroidism include depression, memory loss, myocardial contractility disorder, lipid metabolic disorder, and atherosclerosis. However, the relationship between subclinical hypothyroidism and depression has not been consistent. Therefore, the purpose of this study was to provide the scientific evidence for the relationship between subclinical hypothyroidism and depression. Methods This study was a meta-analysis of depression in subjects with subclinical hypothyroidism. The search engine of PubMed, EBSCO, ScienceDirect, and RISS was used to search the studies published since the 1990s. A total of 176 documents were retrieved from the literature search, and finally 10 studies were included in the analysis. Statistical analysis of effect sizes was performed using Comprehensive Meta-Analysis software version 2.2.064. Results Of the 10 studies, five studies reported that depression was associated with subclinical hypothyroidism. Two of these studies were on women and two were on the elderly. The effect size of depression in patients with subclinical hypothyroidism was 3.46 (95% confidence interval 0.20–0.74, P=0.001), and the subclinical hypothyroidism was significantly associated with depression. Conclusions This study showed that subclinical hypothyroidism is associated with depression. The results also suggest the need for regular screening of depressive symptoms of patients with subclinical hypothyroidism. Especially, elderly and women with subclinical hypothyroidism may be the main targets of depressive symptom.

Objective To study the relationship between subclinical epileptiformdischarge and transitory cognitive impairment, Methods BM800 AEEG Was used to analyse subclinical epileptiformdischarge of 8 patients from August, 1998 to March, 2002. Results The results indicate that 8 patients suffered from subclinical epilep- tiformdischange are all accompanied with TCI. Conclusion The result is show that subclinical epileptifor- mdischarge is connected with TCI. It is necessary to inspecte by AEEG the patients who have difficulties to study but have not obvious symptoms, subclinical.

Objective To analyze the variety and clinic signification of lipids in patients with subclinical hypothyr oidism. Methods The levels of TSH,FT3,FT4,TC,TG,LDL-C,HDL-C in 52 subclinical hypothyroidism patients,60 controls and 55clinical hypothyroidism patients were determined and compared. Results Compared with the control the levels of LDL-C,TSH in clinical hypothyroidism and subclinical hypothyroidism patiens were higher (P0.01); the levels of FT4,TC, TG in clinical hypothyroidism patients were higher (P0.01). The level of TC in subclinical hypothyroidism patiens and FT3 in clinical hypothyroidism patients was higher (P0.05). Compared with subclinical hypothyroidism,the levels of FT4,TC, TG,TSH、FT3 in clinical hypothyroidism patiens was higher (P 0.01 or P 0.05). Conclusion The level of lipids in subclinical hypothyroidism patients is abnormal and it amy be close to clinical hypothyroidism.

Subclinical hypothyroidism affects 4.3% of the US population. Despite this prevalence, whether to treat or to observe patients with subclinical hypothyroidism remains controversial. Guidelines for overt hypothyroidism strongly favor treatment for symptomatic benefits, but the same benefits of levothyroxine treatment have not been proven for patients with subclinical hypothyroidism-most likely due to the asymptomatic nature of the condition. Additionally, a connection between subclinical hypothyroidism and cardiovascular complications has not been definitively established, although the evidence favors a relationship. This article describes the background, presentation, and diagnostics of subclinical hypothyroidism, treatment, and potential cardiovascular complications, so clinicians can decide if initiating treatment is best for their patients with subclinical hypothyroidism.

The authors review current information about the prevalence, causes, course, and consequences of subclinical hypothyroidism. There is evidence that subclinical hypothyroidism may be associated with cognitive dysfunction, mood disturbance, and diminished response to standard psychiatric treatments. Recommendations are presented for the screening, evaluation and treatment of patients in whom subclinical hypothyroidism may be contributing to neuropsychiatric dysfunction.

Subclinical hypothyroidism and hyperthyroidism are diagnoses based on laboratory evaluation with few if any clinical signs or symptoms. Subclinical hypothyroidism is defined as an elevation in serum thyroid-stimulating hormone (TSH) above the upper limit of the reference range (0.45-4.5 mIU/L) with normal serum FT4 concentration; subclinical hyperthyroidism is defined as a decrease in serum TSH below the reference range with normal serum FT4 and T3 concentrations. Though these conditions represent the earliest stages of thyroid dysfunction, the benefits of detecting and treating subclinical thyroid disease are not well established. Most persons found to have subclinical thyroid disease will have TSH values between 0.1 and 0.45 mIU/L or between 4.5 and 10 mIU/L, for which the benefits of treatment are not clearly established; treatment may be beneficial in individuals with serum TSH lower than 0.1 mIU/L or higher than 10 mIU/L. This article illustrates approaches to managing patients with subclinical hypothyroidism and hyperthyroidism through 5 case scenarios that apply the principles of evidence-based medicine. Because of the substantial uncertainty concerning the consequences of untreated subclinical hypothyroidism and hyperthyroidism, as well as the benefit of initiating treatment, patient preferences are important in deciding on management of subclinical disease.
