RESUMEN
Dry eye disease (DED) is pathogenetically based on inflammation of the ocular surface. A step-by-step approach to DED treatment involves early initiation of anti-inflammatory therapy, including instillation of cyclosporine A (CsA). However, recommendations for the use of topical CsA in clinical practice are limited. This article presents an expert consensus on practical recommendations for the management of patients with DED, including indications, time of initiation and duration of CsA therapy, comparison of CsA forms currently registered in the Russian Federation, as well as issues of patient education.

The authors present a case of a child who had severe dietary restriction with consumption of french fries only. He presented to the ophthalmology clinic with light perception vision in both eyes, and was found to have dry, leathery conjunctivae with Bitot's spots and hazy corneas with diffuse punctate epithelial erosions. Electroretinography testing showed an absent rod response and a decreased cone response. Laboratory testing results were positive for vitamin A deficiency. After prompt initiation of treatment, he had improvement in his vision and anterior segment findings. This case serves as a reminder that vitamin A deficiency can present in high-income countries, and that ophthalmologists may play a key role in diagnosing the condition, initiating treatment, and sending patients to the appropriate subspecialists for further evaluation and management of the underlying condition. For patients with vitamin A deficiency, ophthalmologists can play an essential role in preventing permanent vision loss and the systemic consequences of deficiency such as infection or death.

PURPOSE OF REVIEW: Although vitamin A deficiency (VAD) is rare in well resourced countries, there is a growing trend of VAD in at-risk pediatric populations. Early diagnosis is critically important to prevent its associated morbidity and mortality. This review highlights key lessons for evaluation, diagnosis, and management of children with xerophthalmia in the United States. It synthesizes the latest findings from the literature on the pathophysiology, epidemiology, risk factors, evaluation, and management of VAD in low-prevalence areas. RECENT FINDINGS: Vitamin A is crucial for maintaining the functional integrity of the eye, immune system, skin, and mucous membranes. Despite the scarcity of VAD in developed countries, there are increasing reports of VAD in at-risk children, including those with autism spectrum disorder and gastrointestinal conditions. There is a broad range of manifestations of VAD, posing a diagnostic challenge. Familiarity with the variable presentations of VAD and having a high index of suspicion in at-risk populations can aid in its early diagnosis. Systemic vitamin A supplementation and a multidisciplinary approach are important components of the management of VAD. SUMMARY: Even in well resourced countries, VAD should remain on the differential in patients with risk factors who present with relevant signs and symptoms. Early diagnosis and appropriate involvement of a multidisciplinary care team can help prevent morbidity and mortality associated with VAD.

Vitamin A deficiency and xerophthalmia is a rare finding in developed countries. We report a severe case of xerophthalmia in a 7-year-old autistic child with restricted diet. Both eyes had Bitot's spots and ulceration. The right cornea had a perforation at admission. After treatment with high doses of vitamin A the right cornea epithelialized with formation of the anterior chamber and the left eye healed completely. This case adds to the increasing number of reports on cases of xerophthalmia particularly in autistic children and highlights the importance of considering vitamin A deficiency in patients with risk of malnutrition also in developed countries.

ABSTRACT: To compare the clinical efficacy of sodium hyaluronate eye drops, polyethylene glycol eye drops, and compound dextran eye drops in the treatment of dry eye after phacoemulsification of cataract.A total of 99 patients with dry eye after cataract phacoemulsification combined with intraocular lens implantation were treated in our hospital. Patients were divided into group A (sodium hyaluronate eye drops), group B (polyethylene glycol eye drops), and group C (dextran-70 eye drops). The clinical effect, tear film breakup time, basic tear secretion, corneal staining score, dry eye symptom score, and the incidence of ocular irritation were assessed.On the 3rd, 15th, 30th, and 60th day after operation, the tear film breakup time, corneal staining score, Schirmer I test, and dry eye symptom score in group A and group B were better than those in group C (Pâ<â.05). In addition, there were no significant differences in tear breakdown time, corneal staining score, Schirmer I test, and dry eye symptom score between group A and group B (Pâ>â.05). At 3 days to 60âdays after operation, the incidence of dry eye in group A (12.12%) and group B (18.18%) was lower than that in group C (39.39%), and the incidence of dry eye in group A was significantly lower than that in group B (Pâ<â.05).The effect of sodium hyaluronate eye drops elicited a greater beneficial impact as compared to polyethylene glycol eye drops and dextran-70 eye drops.

PURPOSE: To analyse the occurrence and cost of dry eye disease in Spain in the recent years. METHODS: A cross-sectional analysis based on anonymised data from an insurance claims database that includes data from 1997 to 2015 from public and private hospitals and healthcare centres; 36,081 patients were eligible for the study after duplicate elimination. Five ICD9 codes associated with dry eye were used for patient selection, including vitamin A deficiency with xerophthalmic scars of cornea, xerophthalmia due to vitamin A deficiency, keratoconjunctivitis sicca not specified as Sjögren's, dry eye syndrome and keratoconjunctivitis sicca Sjögren's disease. RESULTS: Over 88% of the patients were female, and the mean age was 66 years. Patients with keratoconjunctivitis sicca Sjögren's disease represented more than 89% of all patients and had the highest percentage of women. Both the annual number of patients and the number of admissions have increased exponentially since 1997 raising from 1079 to 3097 and from 1344 to 5938, respectively. The in-hospital length of stay was 9.6 (standard deviation = 11.6) days where more than 65% of the admissions were due to emergencies. Total costs were found to increase from 4.9 to 30.3 million during the study period; in parallel, there was an increase in the mean annual cost per patient, which was on average 7379. CONCLUSION: Disease incidence is likely to increase due to the influence of modern-day workplace, and it is important to take into account the high economic burden and the large decrease in quality of life in regards to Spanish society and health policies.

BACKGROUND: Hyperhidrosis (HH) is characterized by exaggerated sweating in a specific region due to hyperfunction of the sweat glands. In the late 2000s, we started treating patients with an anticholinergic, oxybutynin, that was not being used until then. OBJECTIVES: To present, after 12 years of utilizing this medication in our service, the substantial experience obtained with the use of oxybutynin as an initial treatment of HH in a large series of 1,658 patients. METHODS: We analyzed 1,658 patients treated with oxybutynin for HH from May 2006 to June 2018. The patients were divided into four groups according to the main site of HH: the plantar group, the axillary group, the facial group, and the palmar group. To measure the degree of satisfaction, a quality of life (QoL) questionnaire was used. RESULTS: Pre-treatment QoL was poor or very poor in more than 94% of the cases, and the palmar group had the worst quality of life. After treatment, we observed an improvement in the quality of life in 77% of patients. More than 70% of the patients in all groups present moderate or optimal subjective clinical improvement in sweating after treatment. The group with the best result was the facial group. Intense dry mouth was reported in 24.9% of all patients in all groups. CONCLUSIONS: This study included a large number of patients followed for a long period and demonstrated the good effectiveness of treatment with oxybutynin for hyperhidrosis in the main sites of sweating.

BACKGROUND: Patients who have symptoms of sicca, such as dry eyes and mouth, may have Sjögren's syndrome (SS). However, the conservative culture makes patients hesitate to undergo an invasive biopsy, which contributes to the difficulty of confirming a diagnosis. We aimed to identify the characteristics of patients with sicca symptoms to develop a better predictive value for each item included in the three different diagnostic criteria for SS and clarify the best diagnostic tools for the local population. METHODS: This is a single-center retrospective case-control study from January 2016 to December 2017. Patients who underwent sialoscintigraphy because of clinical symptoms of xerostomia and xerophthalmia at one medical center were reviewed via the patients' electronic medical records. RESULTS: Of 515 patients enrolled, the severity of results for sialoscintigraphy and Schirmer's test was correlated with a diagnosis of SS and generated receiver operator characteristic curve. The area under curve (AUC) was 0.603 for positive Schirmer's test, 0.687 for positive anti-Ro/La results, 0.893 for a positive salivary gland biopsy. The AUC was 0.626 and 0.602 for Schirmer's test which is redefined as <10 mm/5 minutes in either eye and according to 2016 the American College of Rheumatology/ European League Against Rheumatism criteria, respectively. CONCLUSION: Our results indicate the cut-off point for defining a positive test result in the Schirmer's test is worth modified to <10 mm/5 minutes in either eye.

BACKGROUND: Hyaluronic acid (HA) is a popular, nonsurgical, temporary technique that is commonly used in the periocular region to restore volume in areas that have undergone volume loss, as well as adjusting the height and contour of the eyebrow. AIMS: Due to the location of glands, nerves, and vasculature, the facial anatomy should be well understood to avoid injections into areas that may result in complications. PATIENT/METHODS: A 54-year-old woman presented for a cosmetic consultation to address "puffy eyelids". She states she had HA filler injected along the orbital ridge inferior to the eyebrow and medially at the glabellar crease two years prior. Two months after her injection, she began to notice upper eyelid edema, xerophthalmia, and dryness of her nasal mucous membranes. Extensive evaluation and imaging were done by physicians of different specialties with a negative workup. RESULTS: A total of 60 units of hyaluronidase were injected into the areas of previous filler placement over a three-week period. This resulted in complete resolution of the patient's presenting symptoms. CONCLUSION: Familiarity with potential adverse events is arguably the most important aspect of treating patients with HA filler. The anatomy of the orbit and lacrimal system are important to keep in mind when evaluating symptoms related to possible long-term complications of retained filler injections. Reporting this case should raise awareness about this potential adverse event and further explain the delicate anatomy of the periorbital area.

SIGNIFICANCE: Vitamin A deficiency is a known concern in developing countries, but it is often overlooked in developed regions. A history of conditions causing alimentary malabsorption should be considered when patients present with complaints of nyctalopia. PURPOSE: A case of vitamin A deficiency with nyctalopia in a patient with chronic pancreatitis including pertinent diagnostic testing, treatment, and management is presented. The intent is to draw attention to the condition as a differential diagnosis for nyctalopia due to increased prevalence of conditions causing malabsorption. CASE REPORT: A patient with a history of chronic pancreatitis and pancreatic tumor presented with symptoms of nyctalopia and xerophthalmia. Given his systemic history, testing was ordered to determine serum vitamin A levels and retinal function. After results had confirmed depleted vitamin A levels and diminished retinal function, treatment with both oral and intramuscular vitamin A supplementation was initiated to normalize vitamin A levels and improve retinal photoreceptor function. Subjective improvement in symptoms was reported shortly after beginning supplementation, and ultimately, vitamin A levels and retinal function showed improvement after intramuscular treatment. CONCLUSIONS: Detailed case history and a careful review of systems along with serum vitamin A testing and, if available, electroretinography to assess retinal function can help to make a definitive diagnosis. With appropriate comanagement with the patient's primary care physician, it is possible for those with nyctalopia to begin vitamin A supplementation and regain retinal function.

PURPOSE: Sjögren syndrome (SS) is a chronic inflammatory autoimmune disease of the lacrimal and salivary glands. This study compared the concentrations of epidermal fatty-acid binding protein (E-FABP) in the saliva, serum, and tears of SS patients with dry eye and dry mouth, with those of healthy adults to investigate the usefulness of E-FABP as a diagnostic marker for SS. DESIGN: Prospective, observational case series. PARTICIPANTS: The subjects were 11 new patients with untreated Sjogren syndrome and 12 healthy control individuals. METHODS: The diagnosis of SS was in accordance with the Ministry of Health, Labour and Welfare (Japan) Diagnostic Criteria (1999). Saliva, serum, and tear specimens were collected during internal medicine, dental, and ophthalmological examinations. The ophthalmological tests included the Dry Eye-related Quality of life Score (DEQS), tear break-up time (BUT), vital staining with fluorescein (FS) and lissamine green (LG), and the Schirmer test-1. The E-FABP concentration in the tears, saliva, and serum was measured by enzyme-linked immunosorbent assay (ELISA). MAIN OUTCOME MEASURE: The E-FABP concentrations were compared between patients and controls. RESULTS: There were significant differences between the patient and healthy control groups in all ophthalmological test results. There were no significant differences between the groups in the E-FABP concentrations in the saliva (p = 0.1513) or the serum (p = 0.4799), but the E-FABP concentration in the tears significantly differed between groups. The E-FABP concentration in tears tended to be significantly lower in patients with SS (mean, 323.5 ± 325.6 pg/mL) than healthy control subjects (mean, 4076 pg/mL; p = 0.0136). The E-FABP concentration in tears significantly correlated with the results of dry eye parameters. CONCLUSION: The E-FABP concentration in tears appears to be related to ocular surface epithelial damage and tear stability and may be a promising novel biomarker in the diagnosis of SS.

Mucosal dryness is a key clinical feature in primary Sjögren's syndrome (pSS) and its assessment relies on both objective measurement of residual secretion and subjective symptoms reported by patients. However, while the objective assessment and grading of glandular dysfunction can be easily performed, the spectrum of clinical symptoms encompassed by the terms 'dry eye' and 'dry mouth' is wide and heterogeneous. Therefore, patient reported outcomes (PROs) for dryness in pSS poorly correlate with the amount of glandular secretion. In addition, subjective dryness is not correlated with the severity of systemic disease and severely affects the patient quality of life even in presence of active extraglandular manifestations. The purpose of this review article is to provide an overview of glandular dysfunction in pSS as well as the impact of discrepancy between objective assessment, subjective symptom and extraglandular disease activity on disease management.

BACKGROUND: To investigated distinct manifestations of Sjögren's syndrome (SS) patients with neurological complications and the potential risk factors associated with neurological complications in SS, and to produce a disease evaluation and neurological involvement prediction for SS. METHODS: 566 patients who fulfilled the 2002 classification criteria for SS from the Rheumatology Department of the First Affiliated Hospital of Wenzhou Medical University were included in the cross-sectional study. Clinical, immunological and histological characteristics were surveyed, and potential risk factors for neurological complications were examined by multivariate analysis. RESULTS: Among 566 SS patients, 184 (32.5%) patients had neurological involvement, with more than 10% got limbs pain, limbs numbness and cerebral infarction, respectively. Of these 184 SS patients with neurological complications, secondary SS (sSS) patients had a higher prevalence of peripheral nervous system (PNS) involvement than primary SS (pSS) patients (31.1 vs. 19%). And sSS patients showed higher total ESSPRI score and higher prevalence of xerostomia and low C3, C4 levels with more liver, articular involvement and saliva gland atrophy, and more severe lymphocyte infiltration in salivary glands than pSS patients. As for the specific factors associated with neurological involvement, low C3 level were found to be significant in pSS or sSS patients who were younger 50 year old, and ANA positivity, cardiac involvement, saliva gland atrophy were demonstrated to be associated in elder pSS patients. And xerophthalmia was found to be associated in sSS patients. CONCLUSION: Low complement (C3) levels, xerophthalmia, ANA positive, cardiac involvement and labial salivary gland histological result were good ways to predict neurological complications in different subgroups of SS, which might provide insight into better clinical decision-making, especially at early stages of the disease.

This study was conducted to evaluate conjunctival blood flow velocities and microvascular network density in patients with dry eye disease (DED). Twenty-five patients with DED and 25 healthy controls were recruited. The microvasculature and microcirculation of the temporal bulbar conjunctiva of the right eyes were assessed using a functional slit-lamp biomicroscope. Vascular variables included blood flow velocity (BFV), blood flow rate (BFR), microvascular network density and vessel diameter. A fractal analysis was performed using the box counting method to measure the fractal dimension (Dbox) representing the vessel density. The bulbar BFV was 0.59⯱â¯0.09â¯mm/s in the DED group and 0.47⯱â¯0.12 in the control group (Pâ¯<â¯0.001). BFR was 169.5⯱â¯1.8 in the DED group compared to the control group (107.2⯱â¯49.6) (Pâ¯<â¯0.001). Dbox was higher in DED patients (1.65⯱â¯0.04) than controls (1.60⯱â¯0.07, Pâ¯<â¯0.05). Moreover, the vessel diameter was larger in the DED group (21.8⯱â¯1.8⯵m) compared with controls (17.9⯱â¯2.2⯵m, Pâ¯<â¯0.001). Dbox was positively related with ocular surface disease index (OSDI) in patients with DED (râ¯=â¯0.54, Pâ¯=â¯0.008). Microvascular alterations were found in the bulbar conjunctiva of DED patients, including increased blood flow velocity, higher vessel density and larger vessel diameter.

BACKGROUND: Sjögren syndrome (SS) is associated with xerostomia and xerophthalmia. Pilocarpine has been shown to stimulate the secretion of saliva. OBJECTIVES: To investigate and compare the efficacy of pilocarpine and artificial saliva as symptomatic treatments for xerostomia and xerophthalmia in patients with SS. METHODS: A double-blind randomized controlled study was performed. A total of 72 patients with SS were assigned randomly to receive 10 drops of pilocarpine (5 mg) or 10 drops of artificial saliva orally, three times daily for 12 weeks. Whole saliva and tear flow were evaluated at baseline and periodically throughout the study to provide a global assessment of dryness and to report any adverse effects. RESULTS: Patients receiving pilocarpine had a statistically significant improvement in their salivary flow (P < 0·001), lacrimal flow (P < 0·001) and their subjective global assessment (P < 0·001), compared with patients who received artificial saliva. The most common side-effects were sialorrhoea and nausea. CONCLUSIONS: Pilocarpine is more effective than artificial saliva for enhancing salivary and lacrimal secretion in patients with SS. This is the first study to compare the efficacy of pilocarpine and artificial saliva for the treatment of xerostomia and xerophthalmia in SS.

OBJECTIVES: The proprotein convertase enzyme FURIN is a critical regulator of the anti-inflammatory TGFß-1 cytokine and peripheral immune tolerance. In T cells, FURIN is co-regulated with IFN-γ and thus highly expressed in T helper 1 type cells. Previous studies have demonstrated that FURIN is upregulated in inflammatory conditions, including atherosclerosis, rheumatoid arthritis and systemic lupus erythematosus. Here, we evaluated the levels of FURIN in the plasma and peripheral blood mononuclear cells (PBMCs) of patients with primary Sjögren's syndrome (pSS) and in healthy controls. METHODS: FURIN plasma levels were determined by ELISA, and the mRNA expression in PBMCs was quantitated using qPCR. FURIN levels in the plasma were correlated with the clinical and demographic characteristics of the patients. RESULTS: FURIN was found to be significantly upregulated at both the protein and mRNA level in pSS patients compared to healthy controls. In pSS patients, high FURIN protein levels were significantly associated with elevated IFN-γ levels in the plasma as well as a longer duration of sicca symptoms in the eyes. pSS patients with high FURIN levels in their plasma showed a trend towards lower levels of serum beta-2 microglobulin, ESR and a lower systemic disease activity index ESSDAI. CONCLUSIONS: The proprotein convertase FURIN is significantly upregulated in pSS. Elevated FURIN levels associate with high levels of the Th1 type cytokine IFN-γ and long duration of dry eye symptoms. Patients with high FURIN levels show signs of lower disease activity suggesting that FURIN might have a protective role in pSS.
