We report the first Turkish patient with Floating Harbor Syndrome (FHS). The 12-year old male patient exhibited classical dysmorphic features of FHS, mental retardation, celiac disease and additional undescribed findings: microcephaly and cryptorchidism.

Experimental acute sinusitis was induced in 21 New Zealand hybrid rabbits by occluding the ostium and inoculating them with Streptococcus pneumonia. While a group of rabbits with sinusitis was left untreated, two other groups were administered parenteral sodium nitroprussid (SNP) and oral levofloxacin for ten days. While staphylococci species, non-hemolytic streptococcus and contaminated flora were isolated from the sinuses of controls, Streptococcus pneumonia was re-isolated in two of six untreated rabbits, in one of six SNP administered rabbits and none of the levofloxacin treated rabbits. Serum and maxillary sinus mucosal nitric oxide (NO) levels were correlated. While the mean maxillary sinus NO level of controls was significantly higher than that of untreated rabbits, the mean maxillary sinus and serum NO levels were significantly higher in SNP administered rabbits than in the others. Although goblet cell hyperplasia and squamous cell metaplasia were detected in some slides, edema and neutrophil infiltration were the prominent findings. The most severe inflammatory changes were found in the untreated sinusitis group on the third and fifth days. The earliest improvement was observed in the levofloxacin treated rabbits. It was concluded that NO level is decreased during acute sinusitis and that SNP administration hastens the bacteriological and histological recovery.

The histopathological alterations in the vestibule due to aminoglycosides are well defined. Although there are reports comparing the vestibulotoxic effects of the many aminoglycosides, this is the first study to compare the effects of the most commonly used aminoglycosides i.e., streptomycin, gentamicin, amikacin and netilmicin administered both transtympanically and systemically. The transtympanic and systemic administration of each aminoglycoside caused similar histopathological alterations in the vestibule. The most severe degeneration in the cristae ampullaris, utriculus and sacculus was observed after streptomycine administration. The severity of the vestibular damage in terms of magnitude was in the order of streptomycine, gentamicin, amikacin, and netilmicin.

It is known that cigarette smoke induces cytological alterations on the respiratory and olfactory mucosa of the nasal cavity. We evaluated whether cigarette smoking had adverse effects on the epithelium of the vestibule, in the absence of any published ultrasutructural studies. We evaluated ten patients suffering from septum deviation, eight of whom were long-term smokers. While each layer of the epithelium obtained from the non-smokers consisted of a homogeneous cell population, each from the long-term smokers consisted of a heterogeneous cell population. The most prominent changes occurred in the shape and size of the cells and nuclei, the number and length of the cytoplasmic projections, the number and distribution pattern of the desmosomes, and the width of the intercellular spaces. We concluded that cigarette smoke produces hyperplastic and dysplastic changes, important factors related with cancer development, on the epithelium of the vestibule.
