[Vitamin D treatment: hormone therapy for patients who need it or simply a supplementation for everyone?]


[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine (IOM), the target vitamin D level is 20 ng/ml, whereas the Endocrine Society (ES) recommends 30 ng/m as the miminum target value. According to the ES, a 1 ng/ml increase of vitamin D level can be reached by a daily intake of 100 NE, while the IOM recommends 3.6 ng/ml. Moreover, the IOM states that the effect of therapy on serum level is nonlinear. These differences show that the ES and IOM have different views on the risk of adverse effects. The IOM recommends 400 IU vitamin D daily for children younger than 1 year, 800 IU for those above 70 years and 600 IU/per day for everyone else. The ES recommend 400-1000 IU daily for all infants and 1500- 2000 IU for adults. Screening, however, is not recommended by either society. To decrease uncertainty concerning the side effects of higher-dose vitamin D treatment, it is important to understand, use and support the function of the pharmacovigilance system of the pharmaceutical industry that manufactures and markets various (prescription, over-the-counter) preparations. This is what the author aims to highlight in the second part of this article. Using this system, both the doctor and the patient can help support and accept the justification of higher-dose vitamin D therapy.]


[Is a paradigm shift possible in the clinical practice of preventing recurrent fractures?]


[Recurrent osteoporotic bone fractures are less and less considered “natural”, due to the immense variety of products available for treatment. In order to prevent recurrent fractures, treatment should be started in time, and a careful approach is needed to choose the appropriate treatment, and, if needed, to switch therapy. When choosing the therapeutic approach, we have to decide whether it corresponds to the severity of the osteoporosis and the risk of fracture. In order to do this, we have to consider bone quality, previous fractures, the condition of cortical bones and the mode of action of the selected treatment, in addition to the easily evaluated density value. The aim of this article is to provide practical help for the above mentioned decisionmaking process.]


[A simple method to detect urate crystals in formalin-fixed tissue]

BÉLY Miklós, KRUTSAY Miklós

[In our previous study we refuted the thesis that sodium urate crystals are not, or only rarely detectable in formalin-fixed histological samples because they dissolve in the aqueous formalin solution. Our observations indicate that dissolution of urate crystals is primarily caused by haematoxylineosin staining. Undeniably, however, urate crystals are partially dissolved in the aqueous solution of formaldehyde, and thus a small amount of urate deposits may totally dissolve from tissue samples. The aim of the present study was to identify those steps of the staining procedure that are responsible for the dissolution of urate crystals. We found that the dissolution of urate crystals during the course of staining was caused by the combined effects of haematoxylin staining, treatment with 1% aqueous lithium carbonate solution and dehydration with acetone. As the simplest histological method for the detection of urate crystals, we recommend examining unstained sections (mounted with Canada balsam) of formalin-fixed, paraffin-embedded tissue samples in polarised light. According to our previous study, about two thirds of urate crystals remain detectable on unstaied sections, whereas haematoxylin-eosin stained sections of the same tissue samples (derived from patients with gout) did not contain urate crystals. In the samples where urate crystals could be detected in haematoxylin- eosin stained sections using polarised light, the unstained sections contained much more crystals, which shows that dissolution is greatly decreased on unstained sections.]


[Sacral insufficiency fractures]

FERENC Mária, PUHL Mária, VARGA Péter Pál

[BACKGROUND - The spontaneous osteoporotic fracture of the sacrum, known as a sacral insufficiency fracture (SIF) was first described as an unrecognized syndrome of the elderly by Laurie, in 1982. Numerous case histories and a few series of cases have been discussed in medical journals; however, none have been reported in Hungary. GOAL - To delineate the leading diagnostic steps in the recognition of SIF and review the therapeutic guidelines. CASE HISTORIES, METHODS - Between January 2009 and the first six months of 2010 11 cases of SIF were diagnosed at the National Center for Spinal Disorders. We examined the clinical aspects of the illness, the radiological modalities, the fracture markings, the pace of recovery and duration. RESULTS - The 11 patients were found to have various SIF predestining etiological factors and the following classic fractures - H-type, unilateral, horizontal, unilateralhorizontal and vertical as well as a bilateral pattern. In cases often not showing obvious clinical symptoms and in cases resulting in conventional radiological examinations of low sensitivity and specificity, we used mapping techniques in setting up the exact diagnosis. CONCLUSION - If we consider SIF from patient history and known risk factors, diagnostic procedure (primer original) may be shortened and a number of unnecessary tests (biopsy) may be avoided.]


[Infective sacroiliitis]


[INTRODUCTION - Pyogen infection of the sacroiliac joint occurs rarely in rheumatological practice. Its clinical symptoms are diverse, so the diagnosis is often made late. CASE REPORT - The author presents a case of a 67-year-old woman. The patient did not have any major diseases nor any predisposing factors for infection. Five days after doing hard physical work she felt strong pain irradiating from her lower back to the right lower limb. She was referred to the Department of Neurology with the diagnosis of right lumbar radiculopathy. She was primarily examined for tumours because of her high red blood cell sedimentation rate and CRP level and her inability to walk. The correct diagnosis was set up on the basis of MRI examination: infective sacroiliitis on the right side, which has spreaded to the adjacent tissues. USguided biopsy was unsuccesful, so empiric antibioitic treatment was started. The patient was discharged from hopsital after 35 days and continued clindamycin therapy at home. At control examination 6 month later she did not have any symptoms or complaints and laboratory examinations did not indicate inflammatory activity. MRI examination still showed an extensive oedema. CONCLUSION - Pyogen arthritis should be considered even in the absence of fever, leukocytosis and predisposing factors. By making the correct diagnosis and starting long-term antibiotic therapy in time, joint destruction is preventable and the patient is curable.]

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.

A rare entity of acquired idiopathic generalised anhidrosis which has been successfully treated with pulse steroid therapy: Does the histopathology predict the treatment response?

ÖKTEM Özdemir Ece, ÇANKAYA Şeyda, UYKUR Burak Abdullah, ERDEN Simsek Nazan, YULUG Burak

Acquired idiopathic generalised anhidrosis is an uncommon sweating disorder characterized by loss of sweating in the absence of any neurologic, metabolic or sweat gland abnormalities. Although some possible immunological and structural mechanisms have been proposed for this rare entity, the definitive pathophysiology is still un­clear. Despite some successfully treated cases with systemic corticosteroid application, the dose and route of steroid application are controversial. Here, we present a 41-year-old man with lack of genera­lised sweating who has been successfully treated with high dose pulse intravenous prednisolone. We have discussed his clinical and histopathological findings as well as the treatment options in view of the current literature.

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm


The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.
