[Disturbances of the bone metabolism in type 1 diabetic patients]

KERÉNYI ZSUZSA, TAMÁS GYULA, SPEIZER SZABINA, SPEER Gábor, MÉSZÁROS SZILVIA, LAKATOS Péter, HORVÁTH CSABA

[AIMS - Because of contradictory data in literature our aim was to study bone metabolic disturbances and their correlates with anthropometric and metabolic parameters in type 1 diabetic patients (T1DM). Since quantitative bone ultrasound (QUS) measures bone qualities different from BMD, and it has only been scarcely investigated in T1DM, our aim was to describe covariates of QUS parameters. PATIENTS AND METHODS - Osteodensitometry was performed (lumbal spine, femur neck - DEXA; calcaneal ultrasound) on 115 T1DM patients (34 male, 81 female; mean age: 41.4±11 [± SD] yrs; BMI: 23.9±3.0 kg/m2; diabetes duration: 21.6±11.7 yrs; HbA1c: 8.1±1.3%). In addition anthropometric, blood pressure and laboratory parameters (HbA1c, lipids, renal function, fibrinogen, homocystein, PTH, TSH, β-CrossLaps, vitamine D3, osteocalcin, osteoprotegerin) were measured, data using a questionnaire were collected. RESULTS - The prevalence of osteoporosis was 9/112 (8%). A further 21/62 patients with osteopenia were found. Disturbances of bone metabolism have been more frequently proven on lumbal spine (p<0.001). Using multiple linear regression modelling, the independent covariates of osteopathy were systolic blood pressure, body weight, β-CrossLaps and cystatin C. The average broadband ultrasound attenuation (BUA) was 114.2±14.9 in males vs. 108.4±16.3 dB/MHz in females (p=0.07), the mean speed of sound (SOS) 1552±26 in males vs. 1559±32 m/s in females (p=0.32). SOS values in addition to bone density were associated with fracture risk. The independent covariates of BUA were body weight and height (R=0.473, p<0.001), and of SOS only fibrinogen (R=0.305, p=0.032). CONCLUSIONS - According to our results the prevalence of osteoporosis in acceptable controlled T1DM patients is relatively low. The more common metabolic calcipenic osteopathy show a correlation with body weight, markers of bone resorption and diabetic complications/co-morbidities (nephropathy, hypertension) being therefore not only an a priori consequence but also a complication of diabetes mellitus. Our data provide baseline data of QUS in type 1 diabetic patients. Because of the frequency of lower bone mineral content and their known high fracture risk bone metabolism screening of T1DM patients has to be considered.]

[The influence of menopause-related obesity and related changes of body fat distribution on the severity of sleep apnea]

GYŐRFI MÁRIA, SANDRA SÁNDOR, SZAKÁCS ZOLTÁN

[INTRODUCTION - The menopause is associated with an enhanced risk of obesity. During the postmenopausal period changes in the distribution of body fat lead to a variety of disorders. Obesity is among the major risk factors for Obstructive Sleep Apnea Syndrome (OSAS). The prevalence of OSAS increases after the menopause. This study was intended to explore the relationship between the severity of sleep apnea and the quantity, as well as the distribution of body fat in postmenopausal women with this condition. PATIENTS AND METHODS - Sixty-two postmenopausal women (aged 58.6±7.4 years) were studied. Patients suffering from OSAS - established by cardiorespiratory polygraphy - were enrolled. None of the subjects received hormone replacement therapy during the trial. Total and regional quantity of body fat was determined by dualenergy X-ray absorptiometry (DXA). The distribution of body fat, the ratio of android-to-gynoid regional fat, as well as body mass index were automatically calculated by the software of the DXA machine. A specific region was defined to measure the fat content of the cervical region, extending from the mental protuberance to the clavicular plane. The reliability coefficient of the test method was calculated to check the accuracy of regional body fat measurement. The severity of obstructive sleep apnea was determined by cardiorespiratory polygraphy and expressed using the apnea/hypopnea index. RESULTS - Testing for independence in this population revealed the lack of independence between android-type obesity and severe OSAS. Specifically, 74% of patients with severe OSAS were obese (BMI>30 kg/m2). As with the android-type, the khi square test similarly refuted the independence between obesity and the severity of OSAS. Fat content of the cervical region was 25.2% in mild and moderate, and 30.2% in severe OSAS. Two-Sample t-test demonstrated the significant influence of cervical fat content on OSAS severity. CONCLUSION - Elevated BMI, android-type obesity, and higher relative fat content of the cervical region all aggravate obstructive sleep apnea in postmenopausal women.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

The etiology and age-related properties of patients with delirium in coronary intensive care unit and its effects on inhospital and follow up prognosis

ALTAY Servet, GÜRDOGAN Muhammet, KAYA Caglar, KARDAS Fatih, ZEYBEY Utku, CAKIR Burcu, EBIK Mustafa, DEMIR Melik

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

Autonomic nervous system may be affected after carpal tunnel syndrome surgery: A possible mechanism for persistence of symptoms after surgery

ONDER Burcu, KELES Yavuz Betul

After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

Delirium due to the use of topical cyclopentolate hydrochloride

MAHMUT Atum, ERKAN Çelik, GÜRSOY Alagöz

Introduction - Our aim is to present a rare case where a child had delirium manifestation after instillation of cyclopentolate. Case presentation - A 7-year old patient was seen in our outpatient clinic, and cyclopentolate was dropped three times at 10 minutes intervals in both eyes. The patient suddenly developed behavioral disorders along with gait disturbance, and complained of visual hallucinations 20-25 minutes after the last drop. The patient was transferred to intensive care unit and 0.02 mg/kg IV. physostigmine was administered. The patient improved after minutes of onset of physostigmine, and was discharged with total recovery after 30 minutes. Conclusion - Delirium is a rare systemic side effect of cyclopentolate. The specific antidote is physostigmine, which can be used in severely agitated patients who are not responding to other therapies.

Introduction - Peripheral nerve injury (PNI) is a frequent problem among young adults. Hopefully, regeneration can occur in PNI unlike central nervous system. If nerve cut is complete, gold standard treatment is surgery, but incomplete cuts have been tried to be treated by medicines. The aim of the study was to evaluate and compare clinical and histopathological outcomes of independent treatment of each of Vitamin B12 (B12) and Vitamin D3 (D3) and their combination on sciatic nerve injury in an experimental rat model. Materials and methods - Experimental animal study was performed after the approval of BEH Ethics Committee No. 2015/10. 32 rats were grouped into four (n=8) according to treatment procedures, such as Group 1 (controls with no treatment), Group 2 (intraperitoneal 1 mg/kg/day B12), Group 3 (oral 3500 IU/kg/week D3), Group 4 (intraperitoneal 1 mg/kg/day B12+ oral 3500 IU/kg/week D3). Sciatic Functional Index (SFI) and histopathological analysis were performed. Results - SFIs of Group 2, 3, 4 were statistically significantly higher than controls. Group 2 and 3 were statistically not different, however Group 4 was statistically significantly higher than others according to SFI. Axonal degeneration (AD) in all treatment groups were statistically significantly lower than in Group 1. AD in Group 4 was significantly lower than in Group 2 and 3; there was no significant difference between Group 2 and 3. There was no significant difference between Group 1,2 and 3 in Axonolysis (A). But A of Group 4 was significantly very much lower than all others. Oedema- inflammation (OE-I) in all treatment groups were significantly lower than in Group 1; there was no significant difference between Group 2 and group 4. OE-I in Group 2 and 4 were significantly lower than in Group 3. There were no significant differences between Group 1, 2 and 3 in damage level scores; score of Group 4 was significantly lower than of Group 1. Conclusions - B12 and D3 were found effective with no statistically significant difference. But combined use of B12 and D3 improve nerve healing synergistically. We recommend combined use of B12 and D3 after PNI as soon as possible.
