[Primary open angle glaucoma and sleep apnea syndrome: A review of the literature]. / Glaucome primitif à angle ouvert et syndrome d'apnée du sommeil : une revue de la littérature.

The relationship between glaucoma and Obstructive Sleep Apnea Syndrome (OSAS) has long been discussed, with conflicting study findings. OSAS appears in the most recent studies to be more of an aggravating factor than an independent risk factor for glaucoma. Patients with OSAS may develop a more rapid progression of primary open-angle glaucoma (POAG). OSAS may damage the optic nerve not only by increasing the intraocular pressure (IOP) but also by altering the blood supply to the optic nerve as shown by more recent work with OCT-Angiography. Although the systemic benefits of Continuous Positive Airway Pressure (CPAP) have been demonstrated, few studies have evaluated its effect on the optic nerve. CPAP might act on glaucomatous neuropathy by improving the blood supply to the optic nerve. The study of this mechanism of action might provide new insights into the relationship between OSAS and glaucoma.

The prevalence of non-vascular pulmonary manifestations in Takayasu's Arteritis patients: A Retrospective multi-centred Turkish cohort study.

OBJECTIVES: Takayasu's arteritis (TAK) is a rare vasculitis characterized by inflammation of intermediate- to large-size arteries. Although pulmonary artery involvement (PAI) is an expected finding in some TAK patients, data on non-vascular pulmonary involvement (NVPI) are limited. We aimed to investigate the frequency of NVPI, including parenchymal infiltration, nodules/cavities, pleural effusion, and haemorrhage, in TAK. METHOD: We assembled a retrospective cohort of TAK patients from nine tertiary centres in Turkey. The demographics and clinical characteristics of patients were extracted from medical records and the imaging findings were evaluated for pulmonary manifestations. RESULTS: As of January 2021, 319 TAK patients (female/male 276/43; mean age 42.4 ± 13.5 years) were recruited. Eighty-two patients had cough and/or dyspnoea and four had haemoptysis as pulmonary symptoms. On computed tomography assessment, the overall frequency of NVPI was 7.2%; parenchymal infiltrations were present in 10 (3.1%), pleural effusion in eight (2.5%), nodules/cavities in six (1.9%), and pulmonary haemorrhage in four patients (1.3%). In the whole cohort, 10.3% of patients had pulmonary artery hypertension (PAH) and 5.6% had PAI. Among patients with PAH or PAI, the overall frequency of NVPI was significantly higher than in the rest of the group. CONCLUSIONS: In this TAK cohort from Turkey, we observed NVPI in 7.2% of patients, with parenchymal infiltrations being the most common, followed by pleural effusion. Notably, NVPI was more frequent in patients with PAH or PAI. Although not as common as PAI, NVPI should be kept in mind, especially in TAK patients with PAH or PAI.

[S.AGES Study. Collection and follow-up of new sleep apnea cases in patients over 70 years of age and diagnosed in pulmonary and geriatric units]. / Étude S.AGES: recueil et suivi de nouveaux cas de syndromes d'apnées obstructives au cours du sommeil (SAOS), chez des sujets âgés de plus de 70ans, diagnostiqués dans les structures de pneumologie et de gériatrie.

RATIONALE: S.AGES is a prospective cohort of >70-years-old patients with obstructive sleep apnea syndrome having been diagnosed in a pulmonary or a geriatric medical unit. OBJECTIVES: The main objective of S.AGES is to get a description of older patients with OSAS in France. The secondary objectives will be to prospectively describe the management and the treatment of these patients, to describe their 5-years outcome as compared to younger patients in the literature. It will also contribute to better characterize the compliance and tolerance of the treatment and the incidence of comorbidities like respiratory diseases and cardiovascular disorders. METHODS: All consecutive ≥70-years-old patients having received a diagnosis of OSAS (after polygraphy or polysomnography) will be included in the study. All patients will be followed in a pulmonary or a geriatric department. EXPECTED RESULTS: S.AGES should better characterize the OSAS in the elderly patients, the specific management of this disease and its related risk factors. It may also identify the 5-years mortality and morbidity rates in this population.

The prevalence of gout in an urban area of Izmir, Turkey: a population-based epidemiological study.

OBJECTIVES: This study aimed to determine the prevalence of gout in a general Turkish population, according to the American College of Rheumatology (Wallace) criteria proposed for gout classification. METHODS: This study was conducted in two districts of Izmir Province in Turkey, and involved 2835 subjects of ≥ 20 years of age. In the first stage, face-to-face interviews were performed at the subjects' registered households. In the second stage, subjects who gave positive answers in the screening questionnaire were invited to the hospital for a full examination, which included a detailed medical history, medication use and blood tests. RESULTS: A total of 2887 subjects were contacted, and complete interviews were obtained for 2835 (1551 women, 1284 men). A total of 312 subjects (227 women, 85 men) reported experiencing a short period of joint pain accompanied by swelling, redness or reduced range of movement, and 247 (79%) of these patients underwent a detailed clinical examination in the hospital. Gout was diagnosed in 11 patients (8 men, 3 women). We found minimum age- and sex-adjusted prevalence rates of gout of 0.31% (95% CI: 0.16-0.61) in subjects of ≥ 20 years of age, and 0.72% (95% CI: 0.37-1.24) in subjects of ≥ 40 years of age. CONCLUSIONS: Our data suggest that the estimated prevalence of gout (0.31%) is lower than the previously published estimated prevalence of rheumatoid arthritis (0.36%) in the same study population (14 definite rheumatoid arthritis cases among the 2835 subjects).

Takayasu's arteritis in Turkey - clinical and angiographic features of 248 patients.

OBJECTIVE: Takayasu's arteritis (TA) is a chronic, inflammatory vasculitis affecting the aorta and its major branches. Although it is more prevalent in Far-East Asia, the distribution of the disease is worldwide with different vascular involvement patterns and clinical manifestations. The objective of this study was to evaluate the demographic, clinical, angiographic and prognostic features of TA patients in Turkey. METHODS: Clinical and angiographic findings of 248 TA patients (228 female, 27 male) followed at 15 Rheumatology Centers were prospectively evaluated according to a predefined protocol. RESULTS: The mean age was 40.1 years (30.2 years at the clinical onset). Clinical manifestations included constitutional symptoms in 66%, absent or diminished pulses in 88%, bruits in 77%, extremity pain in 69%, claudication in 48%, hypertension in 43% and cerebrovascular accidents (CVA) in 18% of the patients. Renal artery stenosis, aortic regurgitation and pulmonary hypertension were present in 26%, 33% and 12%, respectively. According to the new angiographic classification, type V (50.8%) and Type I (32%) were the most frequent types of involvement. Corticosteroids were the main treatment in 93% of the patients alone (9%) or in combination with immunosuppressive agents (84%). Most frequently preferred immunosuppressive agents were methotrexate (63%), azathioprine (22%) and cyclophosphamide (13%). Remission was observed at least once in 94% of the patients and sustained remission in 71% during follow-up. CONCLUSION: The demographical, clinical and angiographic findings of TA patients in our series were similar to those reported from Japan, Brazil and Colombia. Combination therapies with immunosuppressive agents were the preferred choice of treatment in Turkey.

Early detection of patients in the pre demented stage of Alzheimer's disease: the Pre-Al Study.

OBJECTIVES: The aim of the Pre-Al study is to evaluate and compare the predictive value of different tools for an early identification of Alzheimer's disease. DESIGN AND PARTICIPANTS: Patients coming for consultation to memory clinics without dementia were included if they had an objective memory or attention trouble assessed by a MMSE score > 25 (with at least one missing item at the words recall) and / or an Isaac set test score < 28. All were examined by a neuropsychological battery (Free and Cued Selective Reminding Test, digit ordering test, WAIS-R digit symbol, Trail making test, Benton visual retention test, verbal fluency, confrontation naming and Baddeley's double task test). A subpopulation received an MRI and SPECT assessment. RESULTS AND DISCUSSION: 251 patients were included (mean age: 72.0 years; mean education duration: 10.9 years). Validation of the predictive tests will be based on the comparison of these tests in patients developing dementia and others, after a follow-up of at least 3 years. This paper presents methodology of the study and the population description.

A large-scale outbreak of trichinellosis caused by Trichinella britovi in Turkey.

An outbreak of trichinellosis occurred in Izmir, Turkey, between January and March 2004. The outbreak was caused by the consumption of raw meat balls made of beef deceptively mixed with pork infected with Trichinella britovi. A total of 1098 people who had consumed this food either in 14 restaurants or from the street vendors located in three different neighbourhoods, consulted six different healthcare centres with a wide range of clinical signs and symptoms. Of them, 418 (38.1%) patients fulfilled the criteria for the diagnosis of acute trichinellosis. The most commonly observed signs and symptoms were myalgia (89.2%), arthralgia (69.9%) and eyelid (67%) and facial oedema (65.8%). High levels of creatinine kinase (69.3%) and lactate dehydrogenase (93.8%) with leucocytosis (>10 000/mm(3), 58.9%) and eosinophilia (>1000/mm(3), 60.5%) were the most prominent laboratory findings. All, but 13 of these patients were treated with mebendazole or albendazole. Based on the physicians' assessments of disease severity, 78 (19%) patients were additionally given prednisolone in whom a significantly more rapid recovery of clinical signs and symptoms (e.g. fever, myalgia, facial and eyelid oedema) was observed, with a rapid improvement in leucocytosis, eosinophilia and muscle enzymes, compared with those, who had not received corticosteroids (P < 0.05). Beef illegally mixed with pork of unknown origin, by a wholesale butcher who had sold this product to restaurants and street vendors at a lower price than the prevailing market price of beef, was the cause of this large-scale outbreak in a country with a predominantly Muslim population.

Prevalence of primary Sjogren's syndrome in Turkey: a population-based epidemiological study.

OBJECTIVES: The aim of this study was to determine the prevalence of primary Sjogren's syndrome (pSS) in a general Turkish population according to the latest proposed American-European Consensus Group (AECG) criteria and European-1 (EU-1) criteria. METHODS: The study was conducted in two districts of Izmir and involved 2835 subjects 20 years of age and older. In the first stage, face-to-face interviews were performed at the registered households. In the second stage, subjects reporting symptoms of both dry eye and dry mouth were invited to the hospital for a full examination, which included Schirmer-1, sialometry and serologic tests. In the third stage, a minor salivary gland biopsy was performed as required. RESULTS: A total of 2887 subjects were contacted and a complete interview was obtained for 2835 (1551 female, 1284 male) subjects. A total of 159 subjects (126 female, 33 male) confirmed oral and ocular dryness, and 86 of these patients (54.1%) underwent a detailed clinical examination in the hospital. pSS was diagnosed in 10 patients (nine females) according to the EU-1 criteria, and in six patients (six females) according to the AECG criteria. We found a minimum crude prevalence of 0.21% [95% confidence interval (CI): 0.03-0.29] in the sample population and an age-sex adjusted prevalence of 0.16% (95% CI: 0.06-0.35), according to AECG criteria. According to EU-1 criteria, these prevalence rates were found to be 0.35% (95% CI: 0.10-0.45) and 0.28% (95% CI: 0.13-0.51) respectively. CONCLUSION: The pSS prevalence rates found in the Turkish population in this study were lower than the estimated prevalence rate in a general population.

Early-onset pancytopenia and skin ulcer following low-dose methotrexate therapy.

Pancytopenia is a rare but serious adverse effect of low-dose methotrexate (MTX) sodium therapy, and this case report describes a very early-onset of pancytopenia and cutaneous lesions after three days of ingestion. A 64-year-old man was presented to Emergency Department with weakness, fever, poor appetite, nausea, and vomiting after he had had accidentally ingested MTX tablets (2.5 mg) twice a day for the last three days. On initial examination, several painful lesions in his oral mucosa and a cutaneous ulceration on his right foot were also observed. He had severe pancytopenia, poor kidney functions, and abnormal coagulation parameters. The blood level of MTX was found to be within therapeutic range. He was treated with leucovorine, intravenous antibiotics, and appropriate blood transfusions; he was discharged from hospital without any sequela. Pancytopenia associated with low-dose (cumulative dose of 15 mg in 3 days) MTX therapy had not been reported previously. The Naranjo probability scale showed pancytopenia and skin ulcer associated with low-dose MTX therapy as probable adverse reactions. Risk factors for pancytopenia such as renal insufficiency, hypoalbuminemia, low folate levels, concomitant infections, concomitant use of drugs, and folate supplementation were not identified in our patient. Although pancytopenia associated with low-dose MTX therapy is not expected as early as 3 days after initiation of the therapy, physicians should also be aware of this life threatening adverse effect during the very first days of MTX therapy for rheumatoid arthritis patients.

Design, synthesis and evaluation of potent thymidylate synthase X inhibitors.

Three synthesized series of compounds based on a thiazolidine core allowed identification of potent inhibitors of thymidylate synthase X. The evaluation of the catalytic activity of the enzyme in the presence of these molecules revealed two distinct classes of compounds that inhibit ThyX with submicromolar concentrations, which could lead, after optimization, to effective inhibitors with potential biomedical interest.

Frequency and severity of musculoskeletal symptoms in humans during an outbreak of trichinellosis caused by Trichinella britovi.

Musculoskeletal symptoms such as myalgia are well-known features in the course of trichinellosis; however, the characteristics of musculoskeletal findings have been described in detail in only 1 study. The present study was aimed to determine the joint and muscle symptoms in subjects diagnosed with acute trichinellosis at our rheumatology unit during a Trichinella britovi outbreak that occurred in Izmir, Turkey, in 2004. In total, 98 patients (55 females, 43 males; mean age 32.3 +/- 10.9 yr) were included in the study. A detailed history and full musculoskeletal examination were obtained in each patient. A self-administered questionnaire developed for recording the musculoskeletal symptoms was completed monthly until all the symptoms were resolved. Pain at the joints, restriction of movements (in shoulders, elbows, wrists, knees, ankles, and temporomandibular joints), myalgia, and muscle weakness (neck and shoulder girdle, muscles of the upper and forearm, back, thigh, and calf muscles) were assessed in every patient. Eosinophil counts, serum levels of creatine kinase, and lactate dehydrogenase also were analyzed. The most frequent musculoskeletal symptoms were muscle pain (86 cases [87.8%]), joint pain (83 [84.7%]), subjective muscle weakness (75 [76.5%]), and restriction of joint movements (63 [64.3%]). Calves, upper arm, neck and shoulder girdle, and forearms were the most affected muscle groups. Muscle pain was reported more frequently in the upper than in the lower extremities and during activity. The most frequent painful joints were shoulders, knees, wrists, and ankles. Upper extremity joints were affected more frequently than the lower extremity joints (77.6 vs. 70.4%). Joint pain occurred more frequently at rest. Both muscle weakness and restriction of joint movements were reported in and around the most frequently affected regions. No evidence of arthritis and objective muscle weakness was noted on physical examination in any patient. Musculoskeletal symptoms in the course of T. britovi infection are frequent but with an excellent prognosis. Joint pain in people suffering from acute trichinellosis may occur more frequently than reported previously.

Impaired endothelial function in patients with ankylosing spondylitis.

OBJECTIVE: In recent years, accelerated atherosclerosis and increased risk of cardiovascular events have been described in patients with rheumatic disease, particularly for rheumatoid arthritis and systemic lupus erythematosus. However, the link between inflammation, atherosclerosis and ankylosing spondylitis is controversial. We evaluated the degree of atherosclerosis and endothelial function of ankylosing spondylitis patients ultrasonographically. METHODS: Fifty-four patients with ankylosing spondylitis (37 +/- 11 yr, 29 males, 25 females) and 31 healthy controls (35 +/- 9 yr, 16 males, 15 females) were consecutively enrolled in the study. Serum lipids, creatinine, glucose, and acute-phase proteins were assessed. The Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were also evaluated. Flow-mediated dilatation and endothelium-independent dilatation of the brachial artery and intima-media thickness of the common carotid artery were measured sonographically. RESULTS: Left, right and averaged intima-media thickness of the common carotid artery did not show a statistically significant difference between the ankylosing spondylitis and control groups. However, flow-mediated dilatation was significantly lower in the ankylosing spondylitis patients (14.1 +/- 6.7 vs 17.6 +/- 8%; P = 0.03). Likewise, nitroglycerin-induced dilatation was lower in the patient group, but the difference was not significant (16.4 +/- 6.8 vs 19.8 +/- 10%; P = 0.07). No correlation was detected between flow-mediated dilatation and age, sex, serum lipids, CRP, ESR, smoking habits and disease activity scores. Intima-media thickness of the common carotid artery was positively correlated with age and BASMI score (r = 0.55, P = 0.00; r = 0.22, P = 0.04, respectively). CONCLUSION: This study demonstrates impairment of endothelial function in ankylosing spondylitis.

Cerebrospinal fluid MR dynamics and risk of falls in the elderly.

RATIONALE AND OBJECTIVES: To investigate the relationship between CSF dynamics and risk of falls of unknown origin in the elderly. POPULATION AND METHODS: Phase contrast MR studies allowed CSF aqueductal flow quantification on 23 community-dwelling older people initially explored for mild cognitive impairment. Mobility assessment included report of falls, talking walking test, stance test, one leg standing test, up and go test, and measurement of fast gait speed. RESULTS: History of falls was associated with larger aqueduct, steeper diastolic slopes higher ratios RDV/SD of diastolic volume/CSF systole duration (p

Increased frequency of familial Mediterranean fever in Central Anatolia, Turkey.

OBJECTIVE: It has been observed that familial Mediterranean fever is more prevalent among people coming from central Anatolia in Turkey. To test this observation the frequency of FMF was investigated by afield survey in Sivas, a city located in central of Turkey. METHODS: The survey was conducted in a cohort of 4809 persons selected by systematic sampling from 2 districts of Sivas, with a total population of 83,274. Face to face interviewing was done with registered households using a standard questionnaire developed to screen FMF A second interview was conducted by a rheumatologist and an internist of those individuals who were regarded to have possible FMF. RESULTS: The suspicion of FMF emerged in the cases of 46 individuals during the survey and 36 were interviewed for a second time. FMF was diagnosed in 10 cases. Only one had a previous diagnosis of FMF. The overall frequency of FMF among a cohort of 3,948 inhabitants of Sivas was 1/395 (0.25%). CONCLUSION: This study indicates that the prevalence of FMF in Sivas may be higher than that in general Turkish population, which has been reported to be 0.1%.

The prevalence of rheumatoid arthritis in an urban population of Izmir-Turkey.

OBJECTIVE: To estimate the prevalence of rheumatoid arthritis (RA) in an urban area in Izmir, Turkey. METHODS: The study was conducted in the Balcova and Narlidere districts of Izmir and a total of 2,887 people aged 20 years or older were contacted with a 98.2% acceptance rate. Nine medical doctors administered an RA questionnaire by face-to-face interview. Subjects reporting a history of swelling in at least 2 joints lasting more than 4 continuous weeks or a history of a diagnosis of rheumatoid arthritis, inflammatory joint rheumatism or joint rheumatism were considered as screening positive and they were invited to come in for an examination. RA cases were defined by the 1987 American College of Rheumatology (ACR) criteria modifiedfor use in population studies. RESULTS: A total of 301 subjects (243 women, 58 men), or 10.6% of those who received the questionnaire were screening positive. 240 (79.7%) of these agreed to undergo a clinical examination either in the clinic or at home. Among these, 14 (12 female, 2 male) patients fulfilled the ACR criteria for RA. The prevalence of RA was 0.49% (95% CI 0.27-0.83) in the total population interviewed, 0.77% (95% CI 0.40-1.35) in women and 0.15% (95%CI 0.02-0.60) in men. The age- and sex-adjusted prevalence for the general population was estimated as 0.36%. Five of the 14 RA (36%) cases had not been diagnosed previously CONCLUSION: These data are consistent with the results of other Mediterranean countries. A significant proportion of RA cases remain undiagnosed in the community.

Gemcitabine-induced vasculitis in advanced transitional cell carcinoma of the bladder.

BACKGROUND: Gemcitabine (GEM) is an alternative chemotherapeutic agent for patients with metastatic bladder cancer. It is believed to be a well-balanced agent, having acceptable toxicity and enhanced antitumor activity. The integration of GEM into the initial chemotherapy plan for these patients is still being developed. CASE REPORT: The patient, male, aged 56 years, was suffering from a transitional cell carcinoma of the bladder. Due to frequent local superficial recurrences, radical cystectomy with pelvic lymphadenectomy and continent ileal diversion was performed. Four years after the operation a left inguinal lymphadenopathy was noted and metastatic bladder carcinoma was confirmed on biopsy. Cytotoxic therapy combining GEM and cisplatin and local external irradiation therapy was initiated. The patient developed extensive necrotising vasculitis with muscle damage after the second course of therapy. Chemotherapy was stopped immediately but this was not enough to relieve the symptoms of severe myalgia and swelling, and additional treatment consisting of cyclophosphamide and prednisolone was initiated. CONCLUSION: Although GEM seems to be relatively safe, some unexpected complications may occur during treatment. This case is not common, but it reinforces the need for careful attention to any new symptoms that seem to be unassociated with the primary disease. Prompt evaluation of such symptoms should be carried out in patients receiving GEM therapy.

A case of recurrent pancreatitis due to hyperlipidemia misdiagnosed as familial Mediterranean fever.

Familial Mediterranean fever (FMF) is prevalent among Arabic, Turkish, Armenian, and Jewish people and it must always be considered in the differential diagnosis of patients from these ethnic groups presenting with recurrent abdominal pain with fever. In cases of fever and recurrent abdominal pain, acute pancreatitis is an important clinical condition, which should be considered in the differential diagnosis. Serum amylase concentration in acute pancreatitis is usually more than three times the upper limit of normal. However, in recurrent pancreatitis secondary to hypertriglyceridemia, serum amylase levels, for reasons that are not well understood, may be normal or mildly elevated. Recurrent pancreatitis secondary to hypertriglyceridemia may thus pose a problem in the differential diagnosis and may lead to an erroneous diagnosis of FMF. Measurement of serum triglyceride along with amylase levels should be required for a suspected diagnosis. Computerized examination of the abdomen may need to be undertaken to exclude acute pancreatitis in the presence of hypertriglyceridemia since serum amylase levels may be normal or slightly elevated.
