Kikuchi-Fujimoto disease: the first reported case in Croatia.

Kikuchi-Fujimoto disease (KFD) is an extremely rare disease known to have a worldwide distribution with higher prevalence among Japanese and other Asiatic individuals. KFD presents as benign and self-limited disorder, characterized by regional cervical lymphadenopathy with tenderness, usually accompanied with mild to high fever and night sweats. Less frequent symptoms include weight loss, nausea, vomiting and sore throat. Final diagnosis can only be determined on the basis of typical morphological changes in the lymph node, therefore lymph node biopsy is crucial for proving the diagnosis. Here we present a 16-year-old, native Croatian, Caucasian girl with KFD, as a first case of KFD reported in Croatia. We suggest that this disease should be considered as a possible cause of fever of the unknown origin followed by lymphadenopathy.

The significance of Helicobacter pylori in patients with nasal polyposis.

AIM: To determine the presence of Helicobacter pylori in nasal polyps and the transmission of H. pylori from stomach to nasal polyps. METHODS: In a prospective, controlled clinical research, 35 subjects with nasal polyps and 30 controls with concha bullosa (CB) were involved, and had been subjected to endoscopic sinus surgery (ESS). In the biopsies of removed polyps and CB, polymerase chain reaction (PCR) was used for detecting the H. pylori DNA. Blood samples of the test and control group were evaluated for H. pylori immunoglobulin (Ig) G and A antibodies by ELISA. The test and control group underwent esophagogastroduodenoscopy with taking biopsies from the stomach for PCR detection of H. pylori DNA. RESULTS: In blood samples, specific IgG and IgA antibodies to H. pylori were found in 30 (85.71%) of 35 polyp patients and in 16 (53.33%) of 30 controls. In 10 (28.57%) of 35 patients H. pylori DNA was identified in the nasal polyp tissue, but it was not detected in the CB specimens. H. pylori DNA was found in the stomach mucosa samples of all test and control group of subjects. Significant statistical difference was found in the H.pylori specific IgG and IgA between the test and control group (p less 0.006) and between the polyp and control biopsy specimens of H. pylori DNA by PCR (p less 0.001). CONCLUSION: This research points to the colonisation of nasal polyps with H. pylori, the transfer of H. pylori from stomach to nasal polyps and potential role of H. pylori in emergence of nasal polyps.

Non-functional parathyroid gland carcinoma, a rare malignant tumor of the head and neck.

Carcinoma of the parathyroid gland is a very rare tumor of the head and neck. The largest number of carcinomas are discovered by chance. (intraoperatively, during surgery removal of the parathyroid gland are adenomas). Around 1% of the primary parathyreoidism is caused by the cancer of parathyroid glands. Only 10% of these rare tumors make up dysfunctional cancer of parathyroid glands. There have been 24 cases reported of this disease in the literature. The focus of our study is to present a case of this disease and to review the published literature to date.

Significance of the pepsin from the saliva in the diagnosis and treatment of laryngopharyngeal reflux disease.

Etiopathogenesis of the laryngopharyngeal reflux has not been sufficiently clarified. It is believed that damage to the lining of laryngopharynx in laryngopharyngeal disease occurs in the use of acid and pepsin. The diagnosis of reflux acidic 24-hour Dual probe pH-metry is considered the gold standard. However, since the laryngopharyngeal reflux is often non-acidic new diagnostic methods are been explored, safe diagnosis of the disease according to symptoms of this uncharacteristic disease. In our study on 45 patients with laryngopharyngeal disease, we have proved that tracking the value of pepsin in the saliva of a valuable diagnostic indicator of laryngopharyngeal reflux and a valuable indicator of the success of the treatment.

Angiosarcoma of the hypopharynx: case report.

Angiosarcomas are malignant neoplasias of rapid growth that emerge from endothelial cells. They are rarely found in the area of the head and neck and account less than 0.1% of all head and neck malignancies. In some cases it has been linked to trauma, radiation and angiectasia but the etiology mainly remains unknown. Here we report a case of angiosarcoma of pyriform sinus manifested by dysphagia and dysphonia. The patient underwent endoscopic hypopharyngeal excision followed by radiation therapy with a good result. Our patient remains tumor free after two years. The purpose of this article is to add another case of primary angiosarcoma of a rare site, the hypopharynx.
