[Osteonecrosis of the femoral head associated with pregnancy is a rare condition. Approximately 40-50 cases have been reported, the first one by Pfeifer in 1957. Avascular osteonecrosis is usually caused by factors that impair the bone’s blood supply (intraosseous arterious or venous occlusion, venous stasis, hypertension in the bone marrow). Owing to the cautious use of radiological imaging techniques during pregnancy and the limited experience with this condition, the correct diagnosis is usually made only retrospectively. Thus, total hip replacement is required in most cases. In the third trimester, MRI examination is safe to perform, and in some cases a simple X-ray should be also considered, as timely avoidance of weight-bearing and other therapeutic interventions might help to prevent the arthroplasty. Here, we would like to present a case observed and treated by us, and to overview the options that could facilitate making the correct diagnosis and finding the appropriate therapeutic program.]

[Pain and opportunities for non-pharmacological pain management in intensive neonatological care]

ANDREK Andrea

[Neonatal intensive care and therapeutic process is accompanied with a range of painful interventions. Research data from the past decades revealed that repeated and/or prolonged pain has long-term consequences on the neurobiological development of the premature infant, which has led to an increased attention to the measurement and alleviation of pain. In addition to pharmacological pain relief, more and more alternative pain management methods of varying efficacy are appearing in the provision of care for premature infants. In this study, we introduce non-pharmacological pain treatment methods with proven efficiency that can be applied to complement the pharmacological pain management or as a therapy before any painful interventions in intensive neonatological care. These methods include heart sound and music therapy, nutritive and non-nutritive sucking, swaddling, touching and kangaroo care.]

[Autoimmune pancreatitis in Hungary: a national multicenter study]

[BACKGROUND - Autoimmune pancreatitis (AIP) is an increasingly recognised, special form of chronic pancreatitis, which greatly differs from other forms of chronic pancreatitis. Most papers on this condition have been published in Japan. METHODS - In our multicenter study, we aim to present the characteristics (demographics, clinical symptoms, laboratory and morphological findings, extrapancreatic symptoms, response to therapy, remission) of the first 13 Hungarian cases of AIP. RESULTS - The mean age at presentation was 44.2 years (range: 19-74); 54% of patients were women. New-onset mild abdominal pain (77%), weight loss (38%) and jaundice (31%) were the most common symptoms, with ulcerative colitis as the most frequent (38%) extrapancreatic manifestation. Diffuse pancreatic swelling was seen in 7 patients (54%), and a focal mass in 5 (38%). Pancreatic duct strictures were present in all patients. Serum immunoglobulin-G4 level was elevated in 71% of the patients in whom it was measured. All percutaneous core biopsies (4 patients) and surgical specimens (2 patients), and 2 of the 4 biopsies of the papilla of Vater revealed hystological findings typical for AIP: periductal, diffuse lymphoplasmacytic infiltration, marked interstitial fibrosis, and obliterative phlebitis. Immunostaining revealed IgG4-positive plasma cells in 57% of the patients in whom it was examined. Granulocytic epithelial lesions (GEL) were detected in 3 patients. These patients were younger (mean age 34 years), 66% were women and 6% had ulcerative colitis, whereas the mean age of patients without GEL was 65 years, and the majority of them were men. Steroid treatment resulted in remission of the symptoms in all patients. Because of suspicion of pancreatic tumour, 2 patients with focal AIP underwent partial pancreatectomy. Symptoms relapsed in one patient, but an increased dose of steroid resulted in a remission, which was maintained by azathioprine therapy. CONCLUSIONS - In our first Hungarian cases, we have confirmed previously reported characteristics of AIP. AIP with GEL is frequent among our patients; this condition is more frequent among women and younger patients, and is often associated with ulcerative colitis. If AIP is suspected, the performance of percutaneous biopsy is highly recommended. The therapeutic response to steroid therapy was excellent.]

Atypical type of Hirayama disease: Onset of proximal upper extremity

AYAS Özözen Zeynep, ASIL Kıyasettin

Hirayama disease is a rare, benign motor neuron disease. It has been proposed that the dura mater’s posterior wall lacks sufficient elasticity in the lower cervical region and this causes the tense dura part to displace anteriorly upon flexion. The disease is described as involving unilateral upper extremity with a distal-onset. We reported weakness and atrophy of the proximal part of an extremity in a 45-year-old man who is diagnosed with Hirayama disease. Proximal onset is a rare type of Hirayama Disease. Clinicians must be alert of proximal involvement and the diagnosis should be confirmed with electrophysiological and flexion MRI studies.

[The paraclinical examinations, principally the MRI have an increasing significance in the diagnosis of multiple sclerosis. However, MRI markers also have a prominent role in monitoring of the disease-course and activity, and also in the planning of possible therapeutic changes. In accordance with previously published international guidelines, in this article we propose a protocol for the monitoring the treatment efficacy in multiple sclerosis. This could be the basis of a consensus based guideline to be implemented in Hungary.]

[Diffusion weighted magnetic resonance imaging of metachromatic leukodystrophy - a case report]

PINTÉR Nándor, KOLLÁR Katalin, RUDAS Gábor, BARSI Péter

[We present the case of a 7 years old boy with the juvenile form of metachromatic leukodystrophy. Beside conventional sequences, a diffusion-weighted magnetic resonance study was performed. On T2-weighted images a diffuse hyperintensity of the cerebral white matter with a typical tigroid pattern was seen as a well-known characteristics of the disease. No difference was detectable on T2-weighted images between the different cerebral white matter regions. Diffusion study showed low apparent diffusion coefficient values in the temporal and orbitofrontal regions and normal values in other cerebral regions compared to the normal appearing cerebellar white matter, wich is partly consistent with the previously reported data. The results of early diffusion studies of the disease are not straightforward and the physical and biochemical backgrounds of the diffusion properties still remain unknown. The more data we collect, the closer we get to the understaning of the diffusion changes in metachromatic leukodystrophy.]

[Diagnostic value of MRI in patients with juvenile dermatomyositis]

CONSTANTIN Tamás, PONYI Andrea, BALÁZS György, SALLAI Ágnes, DANKÓ Katalin, FEKETE György, KARÁDI Zoltán

[Diagnosis of juvenile dermatomyositis is based on the presence of proximal muscle weakness, characteristic skin lesions, muscle enzyme elevation in the serum, and may requires the performance of invasive procedures such as electromyography and/or muscle biopsy. Magnetic resonance imaging (MRI) is considered to be an objective non-invasive tool to detect muscle involvement for diagnosis as well as for follow-up studies. We report a case of a 12 years old girl with definitive juvenile dermatomyositis. She received glucocorticoid therapy and achieved remission of the disease. After a long-term relapse free period, she was presented with severe proximal muscle weakness and normal creatinine kinase levels. The laboratory studies did not reveal acute inflammation or infection. In this case MRI was diagnostic to the relapse of juvenile dermatomyositis, with an increased STIR (short tau inversion recovery) signal of proximal muscles. The muscle involvement detected by MRI correlated with functional ability. After she achieved clinical remission, further follow-up MRI scans demonstrated that the affected muscles had returned to normal signal intensity. Findings of dermatomyositis on MRI scans include increased signal intensity in the affected muscles, perimuscular edema, chemical-shift artifact, and increased signal intensity in subcutaneous tissue. MRI is a sensitive technique and proposed to be a good indicator for an early diagnosis of the disease. MRI may also help to guide the muscle biopsy and may enhance the sensitivity of histological examination. After completion of therapy, MRI may be used for monitoring the progress of the disease as signal intensity of affected muscles returns to normal. MRI is also helpful, if the diagnosis is suspected but has not been formally evaluated.]
