The frequency of smoking, quitting and socio-demographic characteristics of physicians of a medical faculty.

BACKGROUND: The aim of this study was to determine the epidemiology of smoking among physicians and to describe their socio-demographic characteristics. SUBJECTS AND METHODS: All professors, associate professors, assistant professors, lecturers and research assistants working for the Faculty of Medicine of Meram, University of Selçuk, were included in the study. Of the 500 subjects, 363 (72.6%) completed the anonymous questionnaire of the survey satisfactorily. The smoking status, age at smoking initiation, daily cigarette consumption and association between current smoking and socio-demographic variables, family characteristics and body mass index were examined. The SPSS software was used to tabulate the data. The chi-square test was used for statistical analysis. RESULTS: The mean age was 34.2 +/- 9.1 years. The rate of ever-smokers was 28.7% (n = 104). The rates of smoking in females and males were 13.4% (n = 15) and 35.6% (n = 89), respectively (p = 0.000). The rate of ex-smokers was 9.9% (n = 36). The rate of never-smokers was 61.4% (n = 223). The mean age at starting smoking was 21.7 +/- 4.9 years. The quit ratio was 25.7% (36/140) [23.3% (27/116) for men and 37.5% (9/24) for women]. Fagerstrom score was averaged 2.8 +/- 2.7 among all smokers. The rate of smoking in the families (p = 0.003) and among close friends (p = 0.000) of the smoker-group was higher than in non-smokers. CONCLUSION: In Turkey, prevalence of tobacco smoking is high among physicians though lower than the general community. This may compromise their role in tobacco control unless they quit smoking.

Successful treatment of Buerger's Disease with intramedullary K-wire: the results of the first 11 extremities.

OBJECTIVE: This study describes a new technique for treatment of Buerger's disease, developed to stimulate angiogenesis, using a Kirschner wire placed in the medullary canal of the tibia. The aim of the study was to evaluate clinical and radiological effects of this technique in patients where medical and surgical therapy had failed. MATERIAL AND METHODS: Eleven extremities (six patients) with Buerger's disease were treated with the intramedullary Kirschner wire technique. Inclusion criteria were chronic critical ischemia, Rutherford Grade II or III, with major arterial occlusion shown by Doppler examination and angiography; failure to respond to non-surgical and surgical treatment; and the need for strong analgesics. RESULTS: The mean follow-up time was 19 months (range, 13-25 months). Satisfactory remission in each patient was obtained within 6 weeks of intervention. A significant improvement in clinical manifestations including reduced rest pain and increased claudication distance was observed. Foot ulcers completely healed after Kirschner wire intervention. CONCLUSION: Despite short-term follow-up and small patient series, the intramedullary Kirschner wire technique can be expected to achieve relief of pain and a decrease in major amputations in patients with Buerger's disease in whom medical and surgical therapy had failed. However, comparative studies with longer follow-up should be done to confirm the benefits of this new treatment.

Spinal pneumorrhachis.

The term pneumorrhachis refers to the presence of air in the spinal canal. There are only a few previously reported cases in the literature. A case of air within the cervical and lumbar subarachnoid spaces, and a second case of air within the cervical subarachnoid space due to traumatic pneumocephalus are presented in this study.

Early MRI findings in stab wound of the cervical spine: two case reports.

MR imaging was found to be the most sensitive modality for the detection of spinal cord abnormalities in the acutely injured spine. Although it is reported that traumatic pneumomyelogram indicates a base-of-skull or middle cranial fossa fracture and is almost certainly associated with intracranial subarachnoid air, early MR imaging may demonstrate subarachnoid air in penetrating trauma of the spinal cord without head injury. We report two cervical-spine stab-wound cases, one of which had subarachnoid air on early MR findings.

Non-invasive imaging methods before fine-needle aspiration in the diagnosis of cervical masses.

A carotid body tumour is a vascular tumour usually located at or around the bifurcation of the carotid artery and originating from the tunica adventitia. Carotid body tumours, which are generally non-functional and asymptomatic, grow slowly, which is why diagnosis can be delayed. Because of the vascular structures, fine-needle aspiration biopsy may be dangerous and impractical. Efficient and reliable methods of diagnosis, such as colour Doppler ultrasound, magnetic resonance imaging, computerised tomography and arteriography, can be useful. We report on a 58-year-old woman with diarrhoea, flushing and a cervical, hard, non-tender, fixed mass. An unsuccessful diagnostic fine-needle aspiration biopsy was performed after palpation of the cervical mass. A carotid body tumour was finally diagnosed. We concluded that non-invasive imaging methods should be evaluated before fine-needle aspiration in cervical masses. It should also be kept in mind that asymptomatic cervical masses may be related to non-local symptoms.

Effects of caffeic acid phenethyl ester and epidermal growth factor on the development of caustic esophageal stricture in rats.

BACKGROUND/PURPOSE: An experimental study was performed to modify the healing response in caustic esophageal burns to prevent stricture development. Two different agents with different modes of actions, caffeic acid phenethyl ester (CAPE) and epidermal growth factor (EGF), were studied. CAPE has antiinflammatory, immunomodulatory, antioxidant, and antimitotic properties. EGF has known properties in supporting wound healing and in protecting esophagus from injuries. METHODS: The model described by Gehanno and its modification by Liu was used to create standard esophageal burns with 50% NaOH. The study was performed with 76 rats in 4 main groups (sham, CAPE, EGF, and control) and 2 subgroups in each for 5 and 28 days of observation. Efficacy of treatment was assessed in 28-day subgroups by measuring weight gain, contrast esophagograms on day 27, histologic evaluation by measuring stenosis index (wall thickness/lumen diameter), and collagen deposition, and biochemically by determining tissue hydroxy proline (OHP) content. RESULTS: In the end of the study, increase rates of mean body weights of the animals in the 28-day subgroups were as follows: sham, 30%; CAPE, 23%; EGF, 22%; and control, 14%. Although all the animals in subgroups significantly gained weight, the mean weight gain was significantly low in controls when compared with sham, CAPE, and EGF groups (P <.05). Contrast esophagograms on day 27 showed no stenosis in the sham, mild stenosis in CAPE and EGF, and severe stenosis with proximal dilatation in controls. Stenosis indices of the subgroups were as follows: sham, 0.29; CAPE, 0.41; EGF, 0.41; control, 0.84. Index was significantly higher in controls (P <.05). Collagen accumulation scores in the esophageal wall were as follows: Sham, 0.0; CAPE, 0.87; EGF, 0.30; control, 2.70. Scores also were significantly higher in controls (P <.05). Tissue (OHP) levels were as follows (mg/g dry tissue): Sham, 1.48; CAPE, 1.53; EGF, 1.90; control, 4.01. Production of OHP was significantly higher in controls. CONCLUSIONS: The results of the parameters in the study indicate that administration of CAPE and EGF has beneficial effects in the prevention of caustic esophageal strictures. Those effects of CAPE may occur through its antiinflammatory, immunomodulatory, and antioxidant properties, and EGF may occur through its induced proliferative properties on the esophagus.

The efficacy of acetazolamide on visual functions in a patient with choroid metastasis of breast carcinoma.

Breast carcinoma is the most frequent cancer in women and is the second leading cause of death. Choroid metastasis of breast carcinoma can be found either at presentation or in remission. It is frequently encountered in disseminated breast cancer with multiple organ metastasis. It has been proposed that the oedema-reducing effect of acetazolamide is due to stimulated ion and fluid removal from the retina to the choroid. A 40-year-old female patient on adjuvant chemotherapy for breast cancer was found to have an isolated choroid metastasis. Clinical and radiological remission was achieved after orbital radiotherapy, chemotherapy and acetazolamide treatment. In this case report, we emphasise the possible beneficial effect of acetazolamide in patients with choroid metastasis.

Ruptured intracranial aneurysm associated with isolated aortic arch interruption.

Interruption of the aortic arch is a very rare congenital defect consisting of discontinuity between the ascending and descending aorta. Few patients survive to adulthood, due to effective collateral arterial flow to the descending aorta. An intracranial aneurysm is reported in only one patient with aortic arch interruption. We report a 16-year-old boy with an isolated aortic arch interruption and a ruptured anterior communicating artery aneurysm.

The crowned dens syndrome: a rare form of calcium pyrophosphate deposition disease.

The crowned dens syndrome has been termed as acute neck pain ascribed to CPPD deposits associated with a tomographic appearance of calcification surrounding the odontoid process. This rare entity resulting in cervical cord compression is generally seen in older female patients. We present a 26-year-old woman with cervical cord compression due to massive calcification in the periodontoid area and discuss the X-ray and CT findings of the disease.

Teratoma presenting as a cystic lesion on the chest wall.

A 28-year-old woman presented with a rare case of chest-wall teratoma. Computed tomography of a cystic lesion located in the anterior chest wall revealed a hyperdense object with the appearance of a tooth. The cystic mass was totally excised via a chest-wall incision without thoracotomy. Pathologic examination showed a benign teratoma containing an immature tooth.

Cervical myositis ossificans traumatica: a rare location.

An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare.

Effects of misoprostol on bone loss in ovariectomized rats.

This study was performed to investigate whether misoprostol (prostaglandin E1 analogue) (Cytotec, Searle, England) is effective for restoration of bone loss. Four-month-old parous female Sprague-Dawley rats (n = 30) were subjected either to bilateral ovariectomy (OVX, 24 rats) or to sham surgery (sham, 6 rats). The OVX rats were divided into four groups 60 days after the surgery. Six of them were killed, and dual-energy X-ray absorption (Norland xr-36, Norland Corporation, Fort Atkinson, WI, USA) measurements were performed, called pretreatment OVX group. The remaining groups (each had 6 rats) treated orally with 0 (control), 100, 200 micrograms/kg/day misoprostol for 60 days. All rats were killed 60 days after having treatment, and bone loss of the lumbar spine was measured by dual-energy X-ray absorption. The bone mineral density was decreased by 25.4% in control group and 23.6% in pretreatment group compared to sham group, but restored by 86% and 96% in groups treated with 100 and 200 micrograms/kg/day misoprostol, respectively. These results suggest that misoprostol restores bone loss in the lumbar spine of OVX rats in a dose-dependent manner.

Loss of nocturnal decline of blood pressure in patients with nasal polyposis.

The objective of this study was to assess the blood pressure pattern in patients with nasal polyposis. Twenty-seven patients with nasal polyposis (18 males and 9 females), ranging in age from 15 to 72 years (mean 37.1 years) were eligible for inclusion in the study. All patients were hospitalized overnight before surgery. After the basal blood pressure measurements were taken, non-invasive ambulatory blood pressure monitoring was carried out. Oxygen saturation was measured via a finger probe and venous blood sampling was taken for catecholamine level during the full night. All measurements were repeated 4 months after nasal surgery. Mean values for nocturnal decline in blood pressure and heart rate before surgery were less marked than those measured after surgery. Mean decline values (+/- SD) were; 4.6 +/- 2.4 mmHg for systolic blood pressure, 5.8 +/- 3.8 mmHg for diastolic blood pressure, and 7.9 +/- 3.9 beats/min for heart rate before surgery, 9.3 +/- 2.8 mmHg, 8.5 +/- 4.1 mmHg and 10.4 +/- 4.3 beats/min after surgery (p < 0.01), respectively. Whereas mean and minimum SaO2 (%) significantly increased (p < 0.01), catecholamine levels decreased (p < 0.05 for adrenaline, p < 0.01 for noradrenaline) after surgery. A correlation was found between BMI and blood pressure as well as between duration of obstruction and blood pressure. Patients who snored had higher blood pressure values than those who did not. Our data show that in cases of nasal polyposis, hypoxia, hypercapnia, snoring, and sleep disorders may develop and persons with nasal polyposis and snoring have an increased risk of hypertension and loss of nocturnal decline in blood pressure.

The stone man: myositis (fibrodysplasia) ossificans progressiva.

Myositis ossificans progressiva (MOP) is a rare hereditary connective tissue disorder characterized by progressive ossification of striated muscle and connective tissue associated with pain and disability. It is presumably transmitted as an autosomal dominant defect. Congenital anomalies of the hands and feet are early signs of this disease. Involvement of the spine, hips and extremities lead to the development of the "stone man" with only less than 600 cases reported in the literature. We present a case of MOP with typical muscle ossifications and skeletal malformations.

Duplicate origin of left vertebral artery with thrombosis at the origin: color Doppler sonography and CT angiography findings.

We describe a rare case of vertebral artery duplication in a patient with vertigo, weakness, and nausea. A color Doppler examination revealed a duplicate origin of the left vertebral artery and a hyperechoic thrombus at the origin of 1 of the duplicated arteries. CT angiography of the lower neck area demonstrated duplicated vertebral arteries on the left side. MR angiography of the vertebrobasilar system did not show duplication, indicating that the duplicated vertebral arteries fused at a level higher than C2.
