RESUMO
The aim of the study was to investigate the association between some lifestyle-attributable risk factors of atherosclerosis, such as body mass index (BMI), oral contraceptives, hormone replacement therapy, smoking and alcohol consumption with breast arterial calcification (BAC) and its intensity on mammograms, and to assess the impact of these lifestyle risk factors on mammography findings of BAC. This prospective study included 300 women aged 47-69, i.e. a group of 149 women with BAC on mammograms and control group of 151 women without BAC. Self-reported BMI, use of oral contraceptives, hormone replacement therapy, smoking and alcohol consumption were recorded by medical interview. The presence of BAC and its intensity on mammography was compared according to the presence of high BMI and use of hormone therapy, smoking and alcohol consumption. The results showed the highest proportion of smokers (28.9%) in the group with mild BAC as compared with the groups without calcification (14.6%) and with intense calcification (12.1%). Women taking oral contraceptives had a higher level of calcified breast arteries but no significant between-group difference was found for high BMI, hormone therapy and alcohol consumption. Thus, study results showed the mammographic finding of BAC to be inadequate to identify women with some lifestyle-attributable risk factors such as BMI, hormone replacement therapy, smoking and alcohol consumption.

The aims were to determine the benefit of bilateral cochlear implantation in a 20 years old patient implanted in Croatia on hearing and speech development. The male patient, after 10 years of deafness, got cochlear implants Med-EL Combi 40+ on both sides in one-stage surgery. The etiology of his deafness was posttraumatic meningitis. Auditory capacity and speech recognition tests were performed for both ears separately and together Average hearing level on the right ear with right cochlear implant switched on started at 62 dB 1 month after the cochlear implantation and was on 55 dB after 10 years. Average hearing level on the left ear with left cochlear implant switched on started at 55 dB 1 month after the cochlear implantation and was on 32 dB after 10 years. Average hearing level on the both ears with 2 cochlear implants switched on started at 35 dB 1 month after the cochlear implantation and was on 27 dB after 10 years. Long-term functional outcomes with bilateral cochlear implantation provides advantages over unilateral implantation including improved hearing level, speech perception in noise and improved sound localization.

The aim of this article is to present clinical features, diagnostic procedures and surgical treatment of a rare ear tumor. We report a case of 78 year old female with hidradenoma of the external auditory canal. Patient had a sensation of pain and fullness with permanent ottorhea from the right ear for one year Temporal bone computed tomography showed a tumor of the external ear, 6 centimeters in diameter, without bone, temporomandibular joint or intracranial invasion; the tumor was limited medially by the tympanic membrane. Biopsy was performed and pathohistology finding was: hydradenoma nodulare atypicum. Surgical intervention and wide tumor removal in general endotracheal anesthesia was performed. One year after the surgery there was no sign of tumor recurrence. Hidradenoma is rare ear tumor arising from the epithelial cells of sweat glands of the external auditory canal. Radiological evaluation and pathohistology confirmation of hidradenoma is necessary and wide excision of the tumor is the treatment of choice.

AIMS: This study was designed to determine if steroids, capsaicin and mitomycin improved skin flap survival in rats, and it has confirmed that thermography is an effective method to measured skin flap vitality. METHODS: Forty female Wistar rats were randomised into four groups. A standardised full thickness inferiorly based dorsal random-pattern skin flap was raised, and a gelatine sponge was placed before suturing between the flap and its recipient bed, soaked with 0.9 % saline in the control group and with capsaicin, methylprednisolone and mitomycin in the experimental groups. Vitality of the flap and of the survival area was measured by infrared thermography. RESULTS: Methylprednisolone statistically significant decrease skin flap necrosis, approximately 56%, when compared with controls (P< 0.05). CONCLUSION: Corticosteroids applied subcutaneously in a single dose on a gelatine sponge produced a statistically significant improvement of the survival of random skin flaps in rats, whereas capsaicin and mitomycin showed no improvement.

AIM OF THE STUDY: To study frequency and type of indications for tonsillectomy in ENT Department of "Sestre milosrdnice" Clinical Hospital, distribution of operations according to the age and sex of the patients. To present history of tonsillectomies. METHODS: Retrospective study, information collected by clinical documentation review (anamnesis, physical findings). RESULTS: In the nine-year period 1995 - 2003 the total number of operations was 4704, 2527 male, 2177 female patients. There were 2692 tonsillectomies, 2011 adenotomies and 1 tonsillectomy "a chaud". The most frequent indication for tonsillectomy was recurrent tonsillitis (72%), followed by adenotonsillar hypertrophy (13%), chronic tonsillitis (12%), focaloses (1%) and peritonsillar abscess (2%). Distribution according to the surgeon: 80% of the operations were performed by specialists, 20% by residents. According to the age of patient: operations were most often performed at the age of 4 (800 patients). CONCLUSION: According to this study the most frequent indication for tonsillectomy was recurrent tonsillitis. Indications for tonsillectomy are clearly defined and as such should be followed.

The aim of the study was to show the difference in the pattern of inflammation, and Th1/Th2 polarization between asthmatic and non-asthmatic patients with CRS, specifically eosinophil activation, local IgE levels in the sinus fluid and tissue, and the severity of inflammation were measured. The maxillary sinus lavages, mucosal biopsies and bacteriological swabs were taken in 17 asthmatic and 36 non-asthmatic adult patients with CRS. The concentrations of IgE, eosinophil cationic protein (ECP), myeloperoxidase (MPO), and tryptase were analyzed and IgE+ cells, eosinophils, lymphocytes and plasma cells were counted. The granulocyte activation markers and IgE in sinus lavages, and the inflammatory and IgE+ cells counts were significantly higher in the asthmatics with the greatest difference in ECP and IgE concentrations. The tryptase concentrations did not differ, but only in the asthmatics they correlated significantly with the IgE concentrations and IgE+ cells count. Asthmatic patients present a distinct subgroup among the patients with chronic rhinosinusitis (CRS). The levels of the cellular markers and IgE in the sinus fluid differ from those of non-asthmatic patients with CRS. The activation of granulocytes (especially eosinophils), local IgE concentrations and the inflammatory cells infiltration are significantly higher in the asthmatics.

The focus was on salivary glands in cysteamine-induced duodenal ulcer and the different effects of antiulcer agents on cysteamine-induced duodenal ulcer in sialoadenectomized but not gastrectomized rats. We tested antiulcer agents on cysteamine-induced duodenal ulcer in rats (agents/kg i.p.) simultaneously with cysteamine 400 mg/kg s.c., rat killed 24 h thereafter subjected to no surgery (normal), to gastrectomy (24 h before) or sialoadenectomy, acute (24 h before) or chronic (21 days before). (i) Ulcerogenesis: cysteamine-induced duodenal ulcer had the same severity and incidence in normal, gastrectomized or acutely or chronically sialoadenectomized rats. (ii) Antiulcer effect under normal conditions or following gastrectomy: in normal or gastrectomized rats all agents tested, gastric pentadecapeptide BPC 157 [currently in clinical trials for inflammatory bowel disease (PL-10, PLD-116, PL-14736, Pliva) (10.0 microg or 10.0 ng), ranitidine (10 mg), atropine (10 mg), omeprazole (10 mg)] inhibited cysteamine-induced duodenal ulcers, acting through gastric acid-independent mechanisms. Following sialoadenectomy, acute or chronic: ranitidine, omeprazole and atropine were completely ineffective, while pentadecapeptide BPC 157 could protect. Thus, we found that contrary to stomach, salivary glands are implicated in cytoprotective agent activity (standard agents were ineffective after sialoadenectomy). Also, gastric pentadecapeptide BPC 157 was consistently associated with a cytoprotective effect, suggesting a beneficial activity distinctive from that of H2-receptor blockers, proton-pump inhibitors and anticholinergics; but probably replacing missing salivary glands factors.
