- Abstract
To determine the influence of a patent foramen ovale and fibroblast growth factor-21 on core temperature (Tc) responses in SCUBA divers. Additionally, we aimed to quantify the individual and combined influences of wetsuit thickness and anthropometric data on Tc changes during the dives. An experimental study comparing the Tc responses between divers with (n = 17) and without a patent foramen ovale (n = 14). A total of 31 divers participated in the study. Tc was measured pre- and post-dive in 17–18 °C sea water using a telemetric pill. Additionally, blood was drawn pre-dive and ~ 1–2 h post-dive for measurement of fibroblast growth factor-21. There was no influence of a patent foramen ovale on the Tc responses during SCUBA diving in either dive profile (p > 0.05). Additionally, there was no influence of SCUBA diving on fibroblast growth factor-21 concentrations (p > 0.05). The strongest positive and significant associations with the ∆ Tc/min were found when multiplying wetsuit thickness in millimeters by body mass (r
2 = 0.3147, p = 0.0010), BMI (r2 = 0.3123, p = 0.0011), and body surface area (r2 = 0.2877, p = 0.0019). There was a significant, negative linear relationship between the body surface area to mass ratio and ∆ Tc/min (r2 = 0.2812, p = 0.0032). These data suggest that Tc regulation during recreational SCUBA diving can be facilitated in part by the appropriate choice of wetsuit thickness for a given set of anthropometric characteristics.

rat, BPC 157 ,bicortical defect ,BPC-157 - Abstract
Gastric pentadecapeptide BPC-157 (currently in clinical phase II for inflammatory bowel disease) was tested in 7 mm diameter surgically created defects of rat calvaria. Insufficient or absence of bone healing is a frequent problem within all surgical fields. This often necessitates treatment by various bone grafting procedures, utilization of osteopromotive membrane techniques, or local delivery of growth-stimulatory factors. Based on the previously recognized positive osteogenic results for gastric pentadecapeptide BPC-157 on non-union fracture, segmental osteoperiosteal bone defect, its pure peptidergic effect with no carrier interference, together with gastric epithelial cells induced osteogenesis, and a hypothetical gastric hormone opposing bone disturbances development (Bone 24 195, 1999), the aims of the present study were to further develope a possibility of osteopromotion by various routes. Rats received agents locally, BPC 157 2 microg, 2 ng/ml or saline, 1 ml bath, at the injury or intraperitoneally once daily BPC 157 10 microg, 10 ng or 10 pg/kg or saline 5.0 ml/kg, first application immediately following injury, last 24 h before sacrifice (3, 7, 14, 21 days post-injury). Both microscopical and densitometry investigation reveal gastric pentadecapeptide BPC-157 improvement of healing of rat calvarial bicortical defect at all of the tested intervals (p

- Abstract
Seven or fourteen days or twelve months after suturing one tube into the pyloric sphincter (removed by peristalsis by the seventh day), rats exhibit prolonged esophagitis with a constantly lowered pressure not only in the pyloric, but also in the lower esophageal sphincter and a failure of both sphincters. Throughout the esophagitis experiment, gastric pentadecapeptide BPC 157 (PL 14736) is given intraperitoneally once a day (10 µg/kg, 10 ng/kg, last application 24 h before assessment), or continuously in drinking water at 0.16 µg/ml, 0.16 ng/ml (12 ml/rat per day), or directly into the stomach 5 min before pressure assessment (a water manometer connected to the drainage port of a Foley catheter implanted into the stomach either through an esophageal or duodenal incision). This treatment alleviates i) the esophagitis (macroscopically and microscopically, at either region or interval), ii) the pressure in the pyloric sphincter, and iii) the pressure in the lower esophageal sphincter (cmH2O). In the normal rats it increases lower esophageal sphincter pressure, but decreases the pyloric sphincter pressure. Ranitidine, given using the same protocol (50 mg/kg, intraperitoneally, once daily; 0.83 mg/ml in drinking water; 50 mg/kg directly into the stomach) does not have an effect in either rats with esophagitis or in normal rats.

- Abstract
We report a simple novel rat model that combines prolonged esophagitis and parallel sphincters failure. The anti-ulcer gastric pentadecapeptide BPC 157, which was found to be stable in gastric juice, and is being evaluated in inflammatory bowel disease trials, is an antiesophagitis therapy that recovers failed sphincters. Twelve or twenty months after the initial challenge (tubes sutured into sphincters for one week and then spontaneously removed by peristalsis), rats exhibit prolonged esophagitis (confluent hemorrhagic and yellowish lesions, thinner epithelium and superficial corneal layer, with stratification derangement); constantly lowered pressure of both sphincters (assessed by using a water manometer connected to the drainage port of a Foley catheter implanted into the stomach either through esophageal or duodenal incision); and both lower esophageal and pyloric sphincter failure. Throughout the esophagitis experiment, BPC 157 was given at either 10 µg/kg, i.p., once a day (last application 24 h before assessment) or alternatively, it was given continuously in drinking water at 0.16 µg/ml (12 ml/rat). This treatment recovers i) esophagitis (macroscopically and microscopically, at either region or investigated time period) and ii) pressure in both sphincters (cmH2O). In addition, BPC 157 (10 µg/kg) or saline (1 ml/rat, 5 ml/kg) was specifically given directly into the stomach; pressure assessment was performed at 5 min thereafter. The effect of BPC 157 is specific because in normal rats, it increases lower esophageal sphincter-pressure, but decreases pyloric sphincter-pressure. Ranitidine, given as the standard drug using the same protocol (50 mg/kg, i.p., once daily; 0.83 mg/ml in drinking water; or 50 mg/kg directly into the stomach) had no effect.

- Abstract
BPPV is generally the most common cause of vertigo, caused by a pinch-off of tiny calcium carbonate crystals (called the otoconia or the otoliths) from the macula utriculi, most frequently due to the degenerative processes or a trauma, whereby the crystals, under the action of gravity in certain head positions coinciding with its direction, arrive to some of the semicircular canals, usually the posterior one, due to the existent anatomical circumstances and relationships, thus creating an inadequate stimulus of the cupular senses while floating through the endolymph and provoking symptoms of a strong and short-term dizziness. Two main clinical forms can be distinguished: canalolythiasis, with an accommodation of otolithic debris in the semicircular canal, and cupulolythiasis, with their location immediately next to the cupular sense. The diagnosis is established by a positive positioning test, Dix-Hallpike for the posterior and the supine roll for the lateral canal. Although one can expect a spontaneous recovery subsequent to few weeks or months, various methods of otolith repositioning to a less sensitive place lead to a prompt improvement while reducing or withdrawing the symptoms completely. These guidelines are intended for all who treat the BPPV in their work, with an intention to assist in the diagnosis and application of an appropriate therapeutic method.

- Abstract
The paper aimed to determine the incidence of colonization of Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae type b and Neisseria meningitidis in the nasopharynges of healthy children in two preschool institutions during winter and spring months, without using antimicrobial treatment or serotyping of these bacteria. In addition to colonization of the above bacteria, the research that continued for 3 months monitored the length of their persistence in and disappearance from children's nasopharynges, children's health statuses, and provision of adequate medical interventions in children demonstrating clinical signs of disease. The ultimate aim of the paper was based on contributing to clearer and more accurate determination of a medical procedure in case of a positive result for bacteria intended to be found in the nasopharynx of a healthy child who spends time in a preschool institution.

- Abstract
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.

- Abstract
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., (© 2011 John Wiley & Sons A/S.)

- Abstract
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.

- Abstract
The impact of bacterial colonization on the severity and pattern of chronic inflammation in rhinosinusitis is not clear. In this study, it was hypothesized that bacterial colonization of the sinus mucosa would have a greater impact on inflammatory response modulation in asthmatic patients than in non-asthmatic patients with chronic rhinosinusitis. In order to test this hypothesis, granulocyte activation was measured and related to bacteria identified in the sinus lavage. Lavages from the maxillary sinuses of 21 asthmatic and 19 non-asthmatic patients with chronic rhinosinusitis (CRS) were microbiologically examined for aerobic and anaerobic growth. Eosinophil cationic protein (ECP), an eosinophil activation marker, and myeloperoxidase (MPO), a neutrophil activation marker, were measured in the sinus lavages. Bacteria were recovered in 20/32 samples from the asthmatics and in 21/33 samples from the non-asthmatics. Gram-positive aerobes and anaerobes were slightly more common than Gram-negative bacteria. A different bacterial profile was found when comparing Gram-negatives between the groups. Concentrations of MPO were significantly higher in samples with bacterial recovery from asthmatic patients, compared to sterile samples of both groups. Concentrations of ECP in the samples from asthmatic patients were significantly higher than in the controls, with no significant difference related to bacterial colonization. Bacterial colonization in chronically inflamed sinuses may have an impact on neutrophil granulocyte activation in patients with bronchial asthma, which was not confirmed for patients with CRS without asthma.

- Abstract
The aim of this study was to provide more information on the causes of sensorineural hearing loss (SNHL) in children cochlear implant candidates in Croatia. The retrospective study included 270 children candidates for cochlear implantation between January 1997 and January 2005 at our institution. The medical assessment of the candidates included the history, physical examination, radiologic evaluation of the temporal bone and audiologic assessment. A family history of SNHL had 82 (30.4%) candidates. The prematurity and/or complicated perinatal course was found in 35 (12.9%) of candidates. Computerized tomography (CT) scan analysis identified 44 (16.3%) candidates presenting with an inner ear malformation. Overall, a definite or probable cause of SNHL was identified in 58.9% of candidates and 41.1% had no obvious cause. The results of the study might give us better insight into the potential causes of SNHL and allow more timely intervention, allowing children with SNHL to reach their potential.

- Abstract
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.

- Abstract
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.
