[Isolation and enumeration of bacteriophages against S. TYPHI, E. coli, and Shigella in the streams of Ankara].
Active bacteriophages were detected agains S. typhi Vi4, E. coli 36 and Shigella YGR in the streams of Ankara, during 27.3.1973 and 19.3.1974. 49 samples were collected from 3 chosen places. Bacteriophages in high concentrations were detected against S. typhi Vi4, E. coli 36 and Shigella Y6R even in 0.0001 ml amounts of these water samples. Besides bacteriophages, salmonella and shigella were detected as well. These studies showed that the streams in Ankara were highly contaminated with bacteria, and that the detergents and other chemicals used for cleaning in houses, which eventually mixed into the streams through sewage, did not have any bactericidal effect on bacteriophages or other pathogen organisms found in these streams.

Reversed roof graft for the severely deviated nose.
A new technique for the correction of the severely deviated nose is described. After submucosal resection of the septum, the nasal hump is resected, reversed, and reinserted. This technique was applied to 27 patients over a four-year period with successful results. The advantages and disadvantages of the method are discussed.

Wineglass pattern for vertical mammaplasty.
The ideal reduction mammaplasty technique should create a pleasing breast shape with minimal scarring. The long and conspicuous scar associated with the classic inverted "T" pattern mammaplasty techniques are not acceptable for many patients. Periareolar mammaplasty techniques cause less scarring, but they have major disadvantages such as scar widening, areolar distortion, and insufficient breast projection. We used a new pattern for vertical mammaplasty to overcome the insufficient breast projection caused by the round block technique and applied it to 51 patients during the last 3 years. This method results in a single vertical scar and a periareolar scar, allows sufficient volume reduction, and provides good breast shape and projection; the results are durable. This procedure is safe, causes few complications, and is easy to learn and perform.

Extracorporeal septoplasty combined with open rhinoplasty.
Extracorporeal septoplasty is a radical solution for the severely deviated nose. The major problems associated with this procedure are fixation of the septal cartilage graft and dorsal irregularities. Extracorporeal septoplasty was performed in combination with open rhinoplasty in 17 patients with severe nasal deformities. In this technique septum was totally removed through the columellar incision of open rhinoplasty, corrected outside, and replaced as a free "L" shaped cartilage graft. The cartilage graft was fixated to the upper lateral cartilages to restore the natural relations of the anatomical structures. Additional rhinoplastic manipulations were also performed. The follow-up period was up to 18 months. The overall result was successful in all patients. Nasal deviation did not recur and secondary revisions were not needed for any patient during follow-up.

A new extrasupported tip graft in the treatment of bulbous nasal tip.
Treatment of bulbous nasal tip is difficult. In the presence of thick, inelastic skin, cartilaginous framework should be supported in special areas. Many tip grafting techniques have been described but the results usually are not satisfactory. We developed a new tip grafting technique to provide extra support and extra length to the nasal tip. The graft is prepared from the septal cartilage and has an extended "A" appearance. The tip graft is supported with a columellar strut graft. Both grafts are inserted into small separate pockets through separate incisions. If necessary, the alar base is reduced with a modified Weir technique. Fifty-two patients were treated with this technique over the last 3 years. Results were satisfactory in all patients without any complications such as graft displacement, infection, or resorption. Extrasupported tip graft is an effective method in the treatment of bulbous nasal tip with thick skin.

Ocular findings in familial adenomatous polyposis.
BACKGROUND: Retinal pigment epithelium (RPE) lesions are predictive congenital phenotypic markers for familial adenomatous polyposis (FAP). This prospective screening study aims at assessing the incidence and significance of these lesions in FAP patients and their family members. METHODS: Sixty-two members from three families including five patients with the diagnosis of FAP have been ophthalmologically surveyed. All RPE lesions were documented with fundus photography and fluorescein angiography was performed in 13 subjects. Sigmoidoscopy and/or radiological examination were performed annually in 9 family members with typical RPE lesions during 4 years to allow early diagnosis of FAP. RESULTS: Typical RPE lesions were present in five FAP patients and 15 family members. Telangiectatic dilatations in the retinal periphery with small dot-like hemorrhages were detected in 6 subjects from 3 families These lesions were particularly evident on fluorescein angiography. Annual colon analysis showed polyps in 3 out of 9 subjects who were positive for RPE lesions. CONCLUSION: RPE lesions are valuable as a clinical marker in predicting FAP. The co-existing peripheral vascular alterations which have not been reported before, are probably related to FAP.

Interleukin-4, interleukin-8 and E-selectin levels in intranasal polyposis patients with and without allergy: a comparative study.
Intranasal polyposis is a chronic inflammatory upper airway disease with unknown aetiology. Interleukin (IL)-4 and IL-8 play very significant roles in allergic events and infectious inflammation, respectively. In contrast, E-selectin is important in the initiation and organization of inflammation. In this study, levels of IL-4, IL-8 and E-selectin were measured in nasal mucosa specimens of intranasal polyposis patients with and without allergic rhinitis, and healthy controls. Healthy controls had significantly higher IL-4 levels than allergic patients and non-allergic patients; IL-4 levels were similar in allergic and non-allergic patients. Allergic and non-allergic patients had significantly higher IL-8 levels than healthy controls; IL-8 levels were comparable in allergic and non-allergic patients. E-selectin levels were similar in all groups. The infection-based theory, represented by IL-8, seems to be more likely than the allergy-based theory, represented by IL-4, for the pathogenesis of nasal polyposis.

Intravenous administration of caffeine sodium benzoate for postdural puncture headache.
BACKGROUND AND OBJECTIVES: In this study, we evaluated the efficacy and safety of prophylactic administration of intravenous caffeine sodium benzoate for postdural puncture headaches (PDPH) on patients administered spinal anesthesia. METHODS: Sixty ASA I and II patients undergoing lower abdominal or lower extremity surgery were included in this study. Patients were randomized by double-blind, placebo-controlled design to receive either 1,000 mL normal saline with 500 mg caffeine sodium benzoate (group C) or 1,000 mL normal saline (group S) during the first 90 minutes after spinal anesthesia administration. The patient's electrocardiogram, non-invasive blood pressure, and pulse oximetry were monitored and recorded. The patients' headaches were evaluated by using the visual analog scale (VAS). At the end of the fifth day, the severity of the headache was classified as follows: no headache = 0; mild headache = 1; moderate headache = 2; severe headache = 3. Analgesic requirements were recorded for 5 days. RESULTS: Visual analog scale scores were significantly lower in group C than in group S. The incidence of moderate and severe headache was significantly higher in group S (11 patients) when compared with group C (3 patients). Analgesic demand was significantly lower in group C than in group S for 4 days. CONCLUSION: Intravenous caffeine sodium benzoate administration during spinal anesthesia is a simple and safe way to minimize PDPH.
