Female and male differences in the survival of patients undergoing resection for lung cancer.
OBJECTIVE: In recent years much attention has been focused on the rapidly increasing incidence of primary lung cancer in women. The aim of this study was to determine gender differences in patients treated surgically for lung cancer. METHODS: We performed a retrospective review of patients who had lung resection for primary lung cancer from January 1994 to December 1998. RESULTS: There were 530 men and 42 women. Women were younger than men (55.6 +/- 10 versus 57 +/- 9.9). The difference was not statistically significant (p = 0.9). The mean cigarette consumption was greater in men than in women (p < 0.001). We observed a higher operative morbidity and mortality rate in men compared to women (p < 0.05). Men had more squamous cell carcinoma (61.7%). In female patients, squamous cell cancer and adenocarcinoma were found with almost the same incidence (35.7% versus 33.3%). There was a significant difference in the distribution of cell types (p < 0.001). Pathologic stages for women were; I = 38.2%, II = 21.4%, IIIa = 21.4%, IIIb = 9.5%, IV = 9.5% and for men; I = 40.4%, II = 26.6%, IIIa = 24%, IIIb = 6%, IV = 3%. There was no significant difference in the stage distribution between genders (p = 0.2). Median survival for female and male patients were 38 +/- 9.2 and 35 +/- 3.2 months. Female patients' survival was longer than male patients but the difference was not statistically significant (p > 0.05). CONCLUSIONS: This study emphasizes sex differences in cigarette consumption, operative mortality and the distribution of cell types of patients with primary lung cancer. These initial results should strongly encourage additional studies in different countries on the interaction between sex and lung cancer characteristics to improve clarity.

Chest wall reconstruction with autologas rib grafts in dogs and report of a clinic case.
OBJECTIVE: Nowadays, in chest wall reconstruction prosthetic materials are generally used. However, the rejections of prosthetic materials and infections frequently occur in chest wall reconstruction, especially after radiotherapy or resection that is performed due to infections. METHODS: We used 10 mongrel dogs and performed resections of 8 cm diameter on their chest walls. In the reconstruction of these defects, in five of the subjects, we used two free rib grafts with periosteum to be resected from the contralateral side and in other five subjects, we used free rib grafts without periosteum. After this experimental study, sternal resection was performed in a 24-year-old man because of sternal osteomyelitis. First to obtain rib grafts with periosteum, partial resection was performed to 5th, 7th, and 9th ribs of the lateral left side. After, total sternal resection, end to end anastomosis was performed to the 2nd, 3rd, 4th and 5th anterior ends of the ribs. RESULTS: Autogeneous rib grafts were found to be enough to provide chest wall stabilization. CONCLUSIONS: The contralateral autogeneous free rib grafts can successfully be used in reconstruction of wide chest wall defects. This method is found to be effective and sufficient to prevent infection, rejection and to provide stabilization.

Epidermoid carcinoma-cell culture supernatant's inhibition of monocyte chemotaxis: evidence for a tumour-mediated effect.
Epidermoid carcinoma-cell culture supernatants obtained from three laryngeal-epidermoid carcinoma patients were tested in the monocyte suspensions of 13 stage I and stage II (TNM) head and neck epidermoid-carcinoma patients and seven healthy controls for its chemotactic inhibitor activity in vitro with a modified Boyden chamber method. Using 2% casein as the chemoattractant, mean values of monocyte chemotaxis and random migration were found to be decreased in the patient group compared to the controls in a simultaneous assay recorded by the "leading front" method. Simultaneous experiments performed with the supernatant revealed a nearly double-fold increase in random migration and depressed chemotaxis in both groups. The supernatant caused a further depression in the chemotaxis of the patients' already-disabled monocytes, which is thought to be representative for advanced stage tumours. The depression of monocyte chemotaxis, especially in the control group, implies the presence of tumour-derived chemotactic inhibitor(s) for monocytes in the supernatant.

Defective monocyte chemotaxis in patients with epidermoid tumors of the head and neck.
Monocyte chemotactic activity was assayed by a modified Boyden-Chamber method using the chemoattractant casein and was found to be impaired in 13 patients with epidermoid tumors of the head and neck. Using 7 healthy subjects as controls, the depression in both monocyte chemotactic activity and monocyte random migration in the patients with tumors was found to be statistically significant by the "leading front" technique (P < 0.05).

[The frequency of group A beta-hemolytic Streptococcus in acute tonsillopharyngitis and therapy with cefadroxil, clavulanic acid-amoxicillin combination and erythromycin in patients unresponsive to procaine penicillin therapy].
In January, February and March 1987, the frequency of Group A beta hemolytic streptococcus among 468 patients with acute tonsillopharyngitis who admitted to Dr. Sami Ulus Children's Hospital was % 41. Ten day procaine penicillin therapy was not successful in the % 29.5 patients. Cefadroxil (Duricef), clavulanic acid-amoxicillin combination (Augmentin) and erythromycin were tried in these patients. While the success rate of Duricef therapy was % 55, the results of other drug therapies were not been successful.

Systematic, combined treatment approach to nasolacrimal duct obstruction in different age groups.
PURPOSE: To report the outcome of a step-by-step treatment approach for congenital nasolacrimal duct obstruction (CNDO). METHODS: Three-hundred and fifty eyes with CNDO were included in the study. A number of treatment methods were applied systematically until a successful outcome was achieved. Listed in order from simple to more complex, the following methods were used: conservative management (massage and topical antibiotics), high-pressure syringing, probing, and silicone intubation. Treatment efficacy was determined according to age (Group 1: 0-6 months, Group 2: 7-12 months, Group 3: 13-24 months, Group 4: 25-72 months) and success rates were compared. RESULTS: Conservative management was applied only in children less than 1 year of age, and was successful in 91.8% of Group 1 and 60% of Group 2 eyes. The difference between these two success rates was significant (p = 0.003). High-pressure syringing was performed in children under 24 months of age, with success rates of 41.7% in Group 1, 33.3% in Group 2, and 12.5% in Group 3. The overall success rate for first probing in all groups was 76.1%, with a range of 69.4% to 80.9%. After second probing, the overall cure rate for the entire cohort was 88.0%, with a range of 74.9% to 94.8%. There was no real difference in probing cure rates relative to age (p > 0.05). Silicone intubation was indicated and performed in two eyes of Group 2 children, three eyes of Group 3, and nine eyes of Group 4. Two ducts in Group 4 eyes remained obstructed after silicone intubation. CONCLUSIONS: The systematic treatment approach to CNDO, including conservative management and minimally invasive procedures such as high-pressure syringing, probing, and silicone intubation, is highly successful. In this study, the cure rate for this combined approach was 100% in youngsters under 2 years of age and 94.5% in children 2 to 6 years old.
