Both sarcoidosis and primary Sjögren syndrome (pSS) are multisystem disorders of unknown etiology, which share certain clinical features, making the differential diagnosis a real challenge in clinical practice. Several published case reports and case series have posed the question as to whether there is a real association - mimicry between the two diseases or it is just coincidence. We attempt, after systematic and comprehensive research of the relevant published literature, to present all those data, clinical or paraclinical, which could be useful in the diagnostic approach and the distinguishment of the two diseases. It is certain that, besides the classic diagnostic methods, emerging is the role of immunology and genetics on this direction, although not established yet.

Hypertension constitutes one of the most common diseases leading patients to the Outpatient Departments. Idiopathic hypertension is the prevailing type, but on the other hand, the possible presence of clinical entities responsible for the development of secondary hypertension should never be underestimated. We retrospectively studied 447 subjects aged between 20 and 84 years old and diagnosed with hypertension, who were thoroughly evaluated for secondary hypertension. Our analysis demonstrated that 35 out of the 447 subjects were finally diagnosed with secondary hypertension, representing a relative frequency of 7.8%. Most common causes of secondary hypertension identified in our study group were: glucocorticoid intake (n = 14), obesity hypoventilation syndrome (n = 6), obstructive sleep apnea (n = 2) and preeclamspia (n = 2). Several other causes are also reported. Our study, conducted in a single center in Northern Greece, confirms previous reports concerning the prevalence of secondary hypertension among Greek patients, shedding light on potential pathophysiologic mechanisms. In conclusion, a high proportion of hypertensive individuals still feature have an underlying cause, thus, diagnostic work-up should be thorough and exhaustive, in order the correct diagnosis to be made and the targeted treatment to be initiated.

Statins are among the most widely prescribed medications worldwide. Acute rhabdomyolysis constitutes a potentially life-threatening side effect regardless of whether statins are administered alone or in combination. The potentially fatal combination of a statin and fusidic acid has been well described in the literature. Acute renal failure can be a direct consequence of this drug-drug interaction. We present a case of a 79-year-old woman who presented to our Emergency Department with a one-week history of limb weakness, myalgia, and inability to stand and walk. The patient had been given fusidic acid to treat Methicillin-Sensitive Staphylococcus Aureus (MSSA) positive dermatitis in the 3 weeks prior to admission, while she continued to take her complete therapeutic regimen, which included atorvastatin. Thus, she developed rhabdomyolysis due to the interaction between fusidic acid and atorvastatin. Herein, we report a life-threatening complication of coadministration of fusidic acid and a statin, which is preventable and predictable. The exact mechanism of the interaction is not fully understood, but coadministration of these two medications must be avoided in clinical practice.
ABSTRACT
Herpes Simplex Virus (HSV) encephalitis is an acute infectious disease of the Central Nervous System (CNS), usually affecting the limbic structures, the median temporal cortex, and the orbitofrontal regions. Its annual incidence has significantly increased over the last 20 years and the mortality rate is 7%, if early diagnosed and treated, and 70%, if left untreated, while it is associated with high rates of morbidity. It should be noted that even when Cerebrospinal fluid (CSF) analysis seems normal, imaging studies are not specific and HSV Polymerase Chain Reaction (PCR) test is negative; the clinician should be more aggressive, if clinical presentation is indicative for HSV encephalitis, by administrating acyclovir early after patient's admission. The latter may be a vital intervention for the patient, modifying the patient's clinical course. Through the presentation of two cases of HSV-1 encephalitis that we managed in our department over the last 1 year and after systematic and comprehensive research of the relevant literature, we aim at showing the crucial role of medical history and physical examination, along with the high index of clinical suspicion, in order to make promptly the diagnosis and administer timely intravenous acyclovir, limiting the possibility of complications during the disease's course.
ABSTRACT
BACKGROUND: Several studies have focused on oxidative stress on diabetes mellitus (DM). Our purpose was to investigate the impact of oxidative stress on progression of diabetic retinopathy (DR) in insulin-dependent type 2 DM patients, measuring serum malondialdehyde (MDA), as well as to examine the effect of vitamin E on DR progression in the above-mentioned patients. METHODS: Participants in the study were 282 insulin-dependent type 2 DM patients with DR. All participants underwent a thorough ophthalmological examination, so as to grade DR, along with serum MDA measurement. All participants received 300mg vitamin E daily for 3 months and were examined again. Serum MDA pre- and post-intake of Vitamin E was the main outcome. RESULTS: Serum MDA was positively associated with DR stage, while there was a statistically significant difference pre- and post-intake of vitamin E in all DR stages. In a subgroup analysis of patients with proliferative DR, there was a significant difference at baseline between patients who have received prior laser photocoagulation and the treatment naïve patients, while after intake of vitamin E, no statistically significant difference was noticed. CONCLUSION: Oxidative stress has been found to play significant role in the pathogenesis and progression of DR, while vitamin E seems to reduce MDA levels and subsequent oxidative stress, suggesting that it might have protective role in DR progression.
ABSTRACT
BACKGROUND: Many of the common systemic diseases present characteristic changes in the fundus of the eye, but fundoscopy is often performed by an ophthalmologist. Our purpose was to assess the value of fundoscopy for the general practitioners (GPs) regarding the diagnosis and management of the cases which they face in daily practice. METHODS: 689 patients were referred by GPs to the outpatient ophthalmology department for fundoscopy during the year 2010. The causes of this referral, the results of ophthalmoscopy and its significance in the final diagnosis were recorded and analyzed. RESULTS: In 22 patients (3.1%), fundoscopy revealed optic disc edema. In 7 patients with head trauma (9.7%), fundoscopy revealed intravitreous haemorrhage and Berlin edema. From the patients with photopsias or floaters, 5 (10.2%) had retinal detachment. Finally, in cases with diabetes mellitus or hypertension, ophthalmoscopy was very important to detect the existence and grade the degree of diabetic or hypertensive retinopathy, if they appeared, and as a result to evaluate the prognosis of the disease. CONCLUSIONS: Fundoscopy is fundamental for the GP, as it may help to confirm or exclude the diagnosis of many common diseases. Nevertheless, there are clinical entities where ophthalmoscopy should be performed by an ophthalmologist, in order to be more specific and accurate, and GP should be able to recognise these cases.
ABSTRACT
An 86-year-old man presented with blurred vision and pain in the left eye. A slitlamp examination revealed anterior uveitis with hypopyon. During the investigation of the uveitis, the diagnosis of tuberculosis was confirmed. Hypopyon is a rare manifestation of uveitis due to tuberculosis.

Drug-induced lupus erythematosus is defined as a lupus-like syndrome temporally related to continuous drug exposure which resolves after discontinuation of the offending drug. Herein, we describe a patient with distinct clinical manifestations of anti-TNF-associated DILE related to infliximab therapy. The patient exhibited clinical and laboratory findings of lupus-like illnesses as well as ocular disorders, such as episcleritis. The main message is that the symptoms of DILE should not be overlooked, although sometimes other systematic conditions may underlie them. As a result, it is very important for the clinicians to evaluate the symptoms of DILE and manage appropriately these cases.
ABSTRACT
A 59-year-old female patient presented at the outpatients' Department of Ophthalmology with epiphora, eyelid swelling, and a foreign body feeling in the right eye. The symptoms were present for 4 months, and the patient was treated as suffering from relapsing conjunctivitis. The slit lamp examination revealed keratitis due to exposure, related with the deficient closure of the eyelids. There was a 2 mm difference in the readings with the Hertel exophthalmometry examination between the eyes. Her medical history was clear, and she was referred for computed tomography of the orbits and brain and biochemical examinations (FT(3), FT(4), and TSH) to investigate the presence of an intraorbital mass. FT(3) was significantly increased and TSH was accordingly low, indicating the diagnosis of Graves' disease, which presented without other signs and symptoms apart from ophthalmopathy. Computed tomography scan excluded the diagnosis of an intraorbital mass. Therefore, it is important not to underestimate the ocular manifestations of systemic diseases.
ABSTRACT
BACKGROUND: Diabetes mellitus (DM) is associated with microvascular complications, such as diabetic retinopathy (DR). DR is one of the main causes of visual loss in individuals aged 20-64 years old. This study aims to investigate the independent associations between the stage of DR and a variety of possible risk factors, including years since DM diagnosis, HbA1c levels, the coexistence of hypertension, age and gender. FINDINGS: 120 patients were recruited in the Department of Internal Medicine, Veroia General Hospital, Veroia, Greece, and the DR stage was defined by an ophthalmologist. Afterwards, the DR association with the aforementioned factors was examined. Univariate and multivariate analysis (multivariate ordinal logistic regression) was performed. At the univariate analysis, there was a positive association between DR severity and age (Spearman's rho = 0.4869, p < 0.0001), years since DM diagnosis (Spearman's rho = 0.6877, p < 0.0001), HbA1c levels (Spearman's rho = 0.6315, p < 0.0001), history of hypertension (2.47 +/- 1.37 vs. 0.50 +/- 0.80 for patients without hypertension; p < 0.0001) and male sex (2.56 +/- 1.41 vs. 2.05 +/- 1.45 for female patients; p = 0.045, MWW). All these factors, except for age, retained their statistical significance at the multivariate ordinal logistic model. CONCLUSIONS: Years since DM diagnosis, hypertension, HbA1c levels and male sex are independently associated with severe DR. The effect of age seems to reflect a confounding association.
