Abstract Diabetes mellitus (DM) represents a systemic disorder which afects different organs. Ocular complications of the DM are the worldwide leading cause of blindness. The most common complications are diabetic retinopathy, diabetic cataract, neovascular glaucoma. Recently many investigations point out that DM can cause comlications at ocular surface as well. Condition such as decreased corneal sensitivity, dry eye or neurotrophic corneal ulceraction are the main clinical manifestations of the diabetic keratopathy (DK). Untreated, these conditions can lead to serious visual acuity decrease. Pathological processes, based on chronic inflammation, due to chronic hyperglycemia, are the main step in the process of DK development. Adequate treatment of the main disease - DM is an imperative in maintaining the healthy cornea without subjective sensations of diabetic patients.

Diabetes morbidity grows steadily despite recent progress in its diagnostics and treatment. Its most frequent complication is retinopathy although thereare increasingly more cases of diabetic cataract, secondary rubeous (neovascular) glaucoma, eyelid diseases, and transient impairment of vision.Aim To analyse late results of ophthalmosurgery in diabetic patients with vision problems.Materials and methods Over 24,000 patients were examined from January 2006 to November 2010 at the Department of Diabetic Retinopathyand Ophthalmosurgery, Endocrinological Research Centre. Results of more than 2660 seances of retinal laser coagulation and about 350 surgicalinterventions for diabetic cataract and secondary neovascular glaucoma were available for analysis.Conclusion Timely and correct application of retinal laser coagulation, modern facoemulsification of complicated cataract and drainage surgeryof uncompensated secondary rubeous glaucoma produces good functional results and permits to preserve or even improve visual acuity. The efficacyof surgical intervention is directly related to the quality of diabetes compensation and depends on the joint efforts of ophthalmologists, endocrinologists,and anesthesiologists.

Diabetes mellitus (DM), characterized by chronic hyperglycemia is one of the most common chronic diseases affecting millions of people worldwide. A significant component of the risk associated with DM is thought to be because of its abnormal lipid ‘triad’ profile. All the associated complications are mainly due to imbalance between generation of free radicals and the antioxidant systems like catalase (CAT) and super oxide dismutase (SOD) enzymes. Moreover, increased level of serum glutamate pyruvate transaminase (SGPT) and serum glutamate oxaloacetate transaminase (SGOT) are considered a consequence of hepatocyte damage. The current study was designed to investigate the antihyperglycemic and antidyslipidemic effects, oxidative stress and liver dysfunction indices of fixed dose combination therapy of sitagliptin [50 mg/70kg body weight (BW)] and β-carotene (5 mg/70kg BW) on streptozotocin (45 mg/kg BW) induced diabetic rats (SIDRs). The study showed that combination therapy induced a significant decrease in blood glucose level (BGL) from 19.09 ± 0.13 to 6.86 ± 0.11 mmol/l in comparison to the control group after daily treatment for three weeks. In case of dyslipidimic effect, combination therapy reduced total cholesterol (TC) (22.96%), triglycerides (TG) (17.54%) and low-density lipoprotein (LDL)-cholesterol (52.25%) levels significantly and increased high-density lipoprotein (HDL)-cholesterol level (55.98%) in comparison with respective diabetic control groups. We also observed that combination therapy lowered SGPT & SGOT level by 46.39% and 37.23%, respectively and increased SOD & CAT enzyme activity by 63.79% and 48.32%, respectively in comparison with diabetic control groups. These changes were significantly better than those of sitagliptin and β-carotene monotherapy. The suggestions of our findings of this research are that combination therapy is more potent than their individual monotherapy and may be beneficial for the treatment of diabetic patients with associated complications.

Cataract in diabetic patients is a major cause of blindness in developed and developing countries. The pathogenesis of diabetic cataract development is still not fully understood. Recent basic research studies have emphasized the role of the polyol pathway in the initiation of the disease process. Population-based studies have greatly increased our knowledge concerning the association between diabetes and cataract formation and have defined risk factors for the development of cataract. Diabetic patients also have a higher risk of complications after phacoemulsification cataract surgery compared to nondiabetics. Aldose-reductase inhibitors and antioxidants have been proven beneficial in the prevention or treatment of this sightthreatening condition in in vitro and in vivo experimental studies. This paper provides an overview of the pathogenesis of diabetic cataract, clinical studies investigating the association between diabetes and cataract development, and current treatment of cataract in diabetics.

Background. Congenital intestinal lymphangiectasia is a disease which leads to protein losing enteropathy. Tortous, dilated lymphatic vessels in the intestinal wall and mesenterium are typical features of the disease. Clinical manifestations include malabsorption, diarrhea, steatorrhea, edema and effusions. Specific diet and medication are required for disease control. Case report. A 19-year old male patient was hospitalized due to diarrhea, abdominal swelling, weariness and fatigue. Physical examination revealed growth impairment, ascites, and lymphedema of the right hand and forearm. Laboratory assessment indicated iron deficiency anaemia, lymphopenia, malabsorption, inflammatory syndrome, and urinary infection. Enteroscopy and video capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy. The patient was put on high-protein diet containing medium-chain fatty acids, somatotropin and suportive therapy. Conclusion. Congenital intestinal lymphangiectasia is a rare disease, usually diagnosed in childhood. Early recognition of the disease and adequate treatment can prevent development of various complications.

Inflammatory complications of the organ of vision in the time of COVID-19 can be manifested as conjunctivitis, scleritis, episcleritis, keratitis, uveitis and optic neuritis. It is essential to collect anamnesis, examine the blood for the presence of COVID 19 and treat these patients with the help of infectious disease specialists. Correct diagnosis of inflammatory ocular complications in the presence of COVID 19 makes it possible to prevent ocular complications, such as: ulcers and corneal penetration; fusion and overgrowth of the pupil,which leadto secondary glaucoma; endoophthalmitis, panophthalmitis and optic nerve atrophy. Timely intensive medical care and adequate treatment of these complications lead to a decrease in disability in this category of patients.Keywords:Ophthalmology, COVID-19,complications, ulcers, endoophthalmitis, panophthalmitis, gastrointestinal tract, cavernous sinus thrombosis

RHEUMAT1C fever is a recurrent disease which in most instances can be prevented. Since both the initial and recurrent attacks of the disease are precipitated by infections with beta hemolytic streptococci, prevention of rheumatic fever and rheumatic heart disease depends upon the control of streptococcal infections. This may be accomplished by (1) early and adequate treatment of streptococcal infections in all individuals and (2) prevention of streptococcal infections in rheumatic subjects. TREATMENT OF STREPTOCOCCAL INFECTIONS IN THE GENERAL POPULATION In the general population about 3 per cent of untreated streptococcal infections are followed by rheumatic fever. Adequate and early penicillin treatment, however, will eliminate streptococci from the throat and prevent most attacks of rheumatic fever. Diagnosis of Streptococcal Infection In many instances streptococcal infections can be recognized by their clinical manifestations. In some patients, however, it is difficult or impossible to determine the streptococcal nature of a respiratory infection without obtaining throat cultures. The following section on diagnosis has been included in order to reduce diagnostic errors and to assist physicians in avoiding unnecessary therapy. The accurate recognition of individual streptococcal infections, their adequate treatment and the control of epidemics in the community presently offer the best means of preventing initial and recurrent rheumatic fever. Common Symptoms Sore Throat—sudden onset, pain on swallowing. Headache—common. Fever—variable, but generally from 101° to 104°F. Abdominal Pain—common, especially in children; less common in adults. Nausea and Vomiting—common, especially in children. Common Signs Red Throat. Exudate—usually present. Glands—swollen, tender lymph nodes at angle of jaw. Rash—scarlatiniform. Acute Otitis Media and Acute Sinusitis —frequently due to the streptococcus. In the absence of the common symptoms and signs occurrence of any of the following symptoms is usually not associated with a streptococcal infection : simple coryza; hoarseness; cough. Laboratory Findings White Blood Count—generally over 12,000. Throat Culture—positive culture for hemolytic streptococci is almost always diagnostic.

The aim. To identify the features of corneal sensitivity of the sick and the fellow eye in bacterial keratitis patients with or without diabetes mellitus. Materials and methods. The analysis was performed on the basis of survey data of 62 type 1 diabetes patients with bacterial keratitis and 43 nondiabetic control patients with bacterial keratitis. The examination was performed at the first visit. In addition to standard ophthalmic examination, the patients underwent fluorescein test, OCT of the anterior segment of the eye, non-contact corneal aesthesiometry. Results and discussion. The average corneal sensitivity threshold in diabetic patients with bacterial keratitis at the first visit at all air flow temperatures exceeded the corresponding indicators in nondiabetic patients of the control group: by 33.5% at an air temperature of 5 °C, by 30.6% at 15 °C, by 28.8% at 20 °C, by 27% at 30 °C, and by 26.1% at 40 °C (p<0.05). The average corneal sensitivity threshold at a temperature of 20 °C in the fellow eye in diabetic patients with bacterial keratitis exceeded that in nondiabetic patients with bacterial keratitis of the control group by 32.9 % (p<0.05). Conclusions. Corneal sensitivity of the sick and fellow eye in patients with bacterial keratitis depends on the presence of diabetes mellitus. The average threshold of corneal sensitivity of the sick and fellow eye in diabetic patients with bacterial keratitis at the first visit exceeds the corresponding values in nondiabetic patients with bacterial keratitis. Keywords: diabetes mellitus, bacterial keratitis, corneal sensitivity.

Chronic hyperglycemia increases oxidative stress, activates inflammatory pathways and reduces nerve growth factor (NGF) among diabetic patients, which contribute to development of diabetic peripheral neuropathy (DPN). Tocotrienol-Rich Vitamin E (Tocovid) possesses potent antioxidant and anti-inflammatory properties which are postulated to target these pathogeneses in order to ameliorate DPN. This study aims to evaluate the effects of Tocovid on nerve conduction parameters and serum biomarkers among diabetic patients. This multicenter, prospective, randomized, double-blind, placebo-controlled clinical trial was conducted on 80 eligible participants. The intervention group (n = 39) was randomly allocated to receive 200 mg of Tocovid twice a day, and the control group (n = 41) received placebo twice a day. At the end of eight weeks, the nerve conduction parameters, as assessed by nerve conduction study, as well as serum biomarkers (NGF, malondialdehyde, vascular cell adhesion molecule 1, tumor necrosis factor receptor 1 and thromboxane B2) were compared between the two groups. Compared to placebo, Tocovid significantly improves the nerve conduction velocities of all nerves (+1.25 m/s, interquartile range [IQR] 3.35, p < 0.001, median nerve; +1.60 m/s, IQR 1.80, p < 0.001, sural nerve; +0.75 m/s, IQR 2.25, p < 0.001, tibial nerve). Meanwhile, the levels of serum NGF were significantly higher in the Tocovid group as compared to placebo at eight weeks post-intervention. Participants receiving Tocovid illustrated highly significant improvement in terms of nerve conduction velocities for all nerves tested after eight weeks of supplementation. In addition, Tocovid supplementation elevated the levels of serum NGF, in which its increase is postulated to reflect enhanced neuronal functions. This novel finding suggests that Tocovid could be a disease-modifying agent targeting serum NGF to improve nerve conduction velocities.
