Vitamin D Deficiency in Acute Coronary Syndrome - Clinically Relevant or Incidental Finding?

OBJECTIVE: Vitamin D deficiency has been associated with cardiovascular disease. The aim of this study was to determine serum concentration of 25 hydroxyvitamin D (25(OH)D) in patients with acute coronary syndrome (ACS) and to assess the prognostic role of serum vitamin D level in ACS patients during 3-year follow up. METHODS: The study included 60 ACS patients hospitalized at cardiology department for ACS between March 2012 and October 2012, and 60 age- and sex-matched control patients without ACS. Standard laboratory testing and vitamin D determination were performed in all study patients. In addition, ACS patients underwent coronarography and were followed-up for 36 months of ACS for major adverse cardiac events (MACE). RESULTS: Patients with ACS had a statistically significantly lower mean 25(OH)D level as compared with control group (35.19 nmol/L vs. 58.08 nmol/L, p<0.001). The lowest mean level of 25(OH)D was recorded in diabetic patients with ACS (30.45 nmol/L). ACS patients were divided into three subgroups according to coronarography findings: single vessel, double vessel and triple vessel coronary artery disease (CAD) with respective serum levels of 25(OH)D of 36.44 nmol/L, 33.65 nmol/L and 31.70 nmol/L. During 36-month follow up, the event-free survival rate was 60% in the ACS group. The ACS patients having sustained MACE during follow up had low serum level of 25(OH)D in the acute phase; however, the difference from ACS patients without MACE during follow up did not reach statistical significance (32.64 nmol/L vs. 37.01 nmol/L). CONCLUSIONS: Patients with ACS have low vitamin D level, which is lowest in diabetic patients with ACS. However, during 3-year follow up, vitamin D failed to prove useful as a prognostic biomarker in ACS patients.

Association Between Serum Vitamin D Level and Glaucoma in Women.

The aim of the study was to determine whether serum vitamin D level is lower in female patients with glaucoma as compared with control group. The mechanism by which vitamin D reduces intraocular pressure is not fully clarified. Almost all tissues possess vitamin D receptor (VDR). The mice lacking VDR (VDR knockout mice) have greatly contributed to the understanding of the general vitamin D physiologic function. VDR has been found in some ganglion layer cells, external and internal nuclear layers of retina, and in retinal pigment epithelium, while VDR epitopes have also been found in the ciliary body epithelium, pointing to the role of this protein in eye physiology. The 1,25(OH)2D3 modulates expression of the genes involved in the regulation of intraocular pressure in non-human primates. Extracellular matrix can be remodeled by 1,25(OH)2D3 treatment. Actin disruption can lead to cell morphology alteration, trabecular meshwork relaxation and intraocular pressure reduction. This observational cross-sectional study included 90 female glaucoma subjects aged 45-55 and 50 glaucoma free female subjects as control group. Results of a pilot study conducted in 20 glaucoma subjects and 20 control subjects are presented below. All study subjects underwent history taking, complete ophthalmologic examination and serum vitamin D determination. The mean serum vitamin D level was 32.31 nmol/L in glaucoma patients and 64.17 nmol/L in control subjects. Serum vitamin D level was statistically significantly lower in glaucoma patients as compared with control group (p<0.05).

Head trauma and posttraumatic epilepsy in Slavonski Brod, East Croatia, 1988-2008.

Posttraumatic epilepsy is result of head trauma. The aim of our research was to establish how many patients after head trauma developed posttraumatic epilepsy (PTE). Retrospectively we analyzed 50 patients with head trauma different severity in period from 1989 to 2008, which we werified radiological, electroenfephalographic, and psychical changes were established according pto psychiatric examination. From 50 patient with head trauma, 40 developed seizures (3 in the firs 24 hours and 6 after first 24 hours to the end of first week, 31 after first week). By introducing antiepileptic therapy (AETh), 30 patients were seizure free, 10 patients had 1-2 epileptic seizure monthly (EPA/CPA), 10 patients got prophylactic AETh in period 6-12 months. 14 patients developed psychical changes which were verified by psychiatrist. The experience and literature show that posttraumatic epilepsy is good for treating with 1 or 2 antiepileptic, and remission is more difficult in case psychiatric comorbidity.

Optic nerve sheath meningioma: a case report with 15-year follow-up.

Meningiomas are benign neoplastic lesions of arachnoidal cells of the meninges. These tumors may arise wherever meninges exists, such as in the nasal cavity, paranasal sinuses, middle ear, and mediastinum. Optic nerve sheath meningiomas (ONSMs) are usually unilateral and occur predominantly in middle-aged females, although they may be present at any age. We present a case of a 55-year-old female with ONSM diagnosed when she was 40 years old. Diagnosis and follow-up was based on the clinical picture, CT orbit scan, and magnetic resonance imaging.

Extranodal lymphomas of head and neck with emphasis on NK/T-cell lymphoma, nasal type.

PURPOSE: To determine the occurrence, clinical course and outcome of our patients with natural killer/T-cell lymphoma (NKTCL), nasal type. The nasal type of natural killer/T-cell lymphoma (NKTCL), is rare in the European population but is more frequent in Asia, Central and South America where it accounts for 15-20% of all non-Hodgkin lymphomas (NHL). This type of lymphoma is characterized by tissue necrosis and destruction of the nasal cavity and upper aero-digestive tract. The disease is closely associated with Epstein-Barr virus (EBV) infection and has an aggressive clinical course, poor clinical outcome and high resistance to chemotherapy. PATIENTS: 63 patients with NHL were treated in our department between 2006 and 2011. Eleven patients were diagnosed with extranodal lymphoma, 6 in the area of head and neck. Three of them belonged to NKTCL, nasal type group (4.7%), 1 was diffuse large B cell lymphoma and 2 were marginal zone lymphomas. CONCLUSION: Two out of 3 patients with nasal type NKTCL, had extremely aggressive disease resistant to applied chemotherapy (anthracycline containing regimen), while 1 patient remains in complete remission 6 years after diagnosis.

Postoperative quality of life after two different methods of tonsillectomy.

BACKGROUND AND OBJECTIVES: Tonsillectomy is a very painful procedure. Pain may be severe, and patients are often unable to perform in school or eat regular food for a number of days after the surgery. The aim of this study was to compare the quality of life after undergoing two different surgical techniques of tonsillectomy, harmonic scalpel and classic tonsillectomy with bipolar cauterization. DESIGN AND SETTING: Prospective randomized double-blind, clinical trial study conducted in the ENT Department, Dr. Josip Bencevic General Hospital, Slavonski Brod, Croatia. PATIENTS AND METHODS: Data were collected, according to the type of operation, on pain persistence and intensity and returning to normal eating with tonsillectomy patients during the first seven postoperative days. Group A consisted of 50 children submitted to classic tonsillectomy with bipolar cauterization, while group B included 50 children operated on using the harmonic scalpel. Data on pain intensity were obtained using pain measuring scales adjusted to children's age (Faces scales, visual analog scale). The first day of normal oral food intake was recorded. RESULTS: The analysis of variance revealed that the grade of pain significantly differs by a surgical technique employed, and that it significantly varied over the first seven postoperative days. The pain was more severe after undergoing the harmonic scalpel technique and children started to eat later compared with the classic tonsillectomy. CONCLUSION: The classic tonsillectomy method with bipolar cauterization is the method of choice due to lower postoperative pain levels and sooner normal eating. The quality of life is better after undergoing the classic tonsillectomy method.

Neuroretinitis caused by Bartonella quintana.

A 57-year-old woman presented to the eye clinic for impaired vision on the left eye persisting for three months. Clinical examination revealed massive peripapillary exudate and stellate macular exudate, raising suspicion of a cat-scratch disease. Tetracycline therapy was introduced, followed by azithromycin and topical corticosteroids. Serologic testing for Bartonella henselae and Bartonella quintana was performed. In the first sample, Bartonella quintana IgG titer was 128, and IgM titer 20, whereas in repeat sample the respective findings were 64 and negative. Such a titer dynamics pointed to Bartonella quintana infection. The prescribed therapy resulted in vision improvement and normalization of the clinical picture. After nine months of therapy initiation, macular exudate had almost completely disappeared. Based on the patient's history, symptoms, therapeutic response and IgM pattern, the neuroretinitis must have developed secondary to Bartonella quintana infection.

Giant aneurysm of basilar artery.

In the article we showed the patient, a woman with unruptured giant aneurysm of basilar artery, we showed the done examinations, and therapy dilemmas about what to do in the given case. We found in literature a number of examples which suggest operation treatment, but of embolisation too, some suggest conservative treatment.
