Alternative impression technique for a speech-aid prosthesis.

OBJECTIVE: Prosthetic treatment for speech disorders attributable to surgically acquired soft palate defects are introduced. CASE: A patient who underwent soft palate resection for cancer is presented. The resected portion of the soft palate was confined to the posterior segments. A prosthesis with a speech bulb was adapted to the patient. CONCLUSION: Excellent restoration of speech and improvement of velopharyngeal function was achieved following placement of the special prosthesis.     

Lung re-expansion and urinary lipid peroxidation in neonatal pneumothorax.

AIM: Experiential studies suggest that re-expansion of a collapsed lung may result in pulmonary ischaemia-reperfusion injury. We aimed to evaluate the effect of lung re-expansion on urinary lipid peroxidation products in neonates with pneumothorax. METHODS: This study included 20 mechanically ventilated neonates with pneumothorax, and 18 healthy neonates (controls). A chest tube was inserted immediately following the diagnosis of pneumothorax. Urine samples were obtained just before tube thoracostomy (first period), after one hour (second period), every 12 hours by complete reexpansion (third period). Vital signs and ventilatory parameters were recorded. Urinary lipid peroxidation was evaluated by measurement of thiobarbituric acid-reacting substances (TBARS). RESULTS: No significant difference was found between urinary TBARS concentrations in the first, second and third periods (4.08 +/- 2.4 nmol/L, 2.8 +/- 2.3 nmol/L and 3.3 +/- 2.1 nmol/L, respectively). Control TBARS levels (4.1 +/- 2.1 nmol/L) did not significantly differ from those of the neonates with pneumothorax (p > 0.05). The neonates with pneumothorax had higher heart rates compared to the controls (p < 0.01). When compared with controls, the systolic pressure was lower in all periods (p < 0.01), and diastolic blood pressure was lower only in the first and second period (p < 0.05). Oxygen saturation significantly decreased in the first period compared to saturation of the second period and of controls (p < 0.01). Ventilatory parameters did not show any significant difference between the periods. CONCLUSIONS: This prospective study showed that re-expansion of the lung did not significantly affect urinary TBARS concentration in neonatal pneumothorax. Indirectly, short-term lung collapse followed by re-expansion might not cause a clinically significant reperfusion injury in newborns.     

Osseous destruction and rupture of the extensor tendon caused by sarcoidosis of the finger.

We describe a woman with osseous destruction and rupture of the extensor tendon as a result of sarcoidosis in the left third finger with no evidence of systemic involvement. The tendon was repaired and she was successfully treated with prednisone.     

Prevention of oral mucositis due to 5-fluorouracil treatment with oral cryotherapy

INTRODUCTION: One of the most common and important side effects of 5-fluorouracil (5-FU) is mucositis with ulcerations in the oral cavity. We investigated the effects of local cryotherapy on mucositis incidence administrated durng 5-FU treatment. METHODS: In a total of 99 courses, 5-FU and folinic acid combination chemotherapy was given to 40 patients. In our study, we considered every course as a single case, and cryotherapy was given to the same patient in one course but not given in the next. RESULTS: While mucositis developed in 6.7% of the courses given with cryotherapy, this ratio was 38.9% in courses given without cryotherapy. In the logistic regression analysis, development of mucositis had been found to correlate only with cryotherapy. Odds ratio (OR) = 11.5; in the 95% confidence interval (CI) = 3.2 - 41.9; (p = 0.001). DISCUSSION: Results of initial studies evaluating the effects of cryotherapy in preventing mucositis due to 5-FU based chemotherapy regimens were promising. We concluded that oral cooling prevents 5-FU induced mucositis. This effective prophylactic treatment should be used in patients who are at increased risk for developing 5-FU induced mucositis.     

Nocturnal penile tumescence as a biologic marker in assessing erectile dysfunction

Recent findings challenge the belief that most cases of impotence are psychogenic. Research indicates that nocturnal penile tumescence (NPT) can be viewed as a biologic marker for physiologic erectile capacity. Thus, the test can help to distinguish between physicogenic and psychogenic impotence. To determine proximal causes of erectile failure, other evaluations are easily performed during NPT monitoring.     

Upper and lower gastrointestinal endoscopical investigation in elderly patients with iron deficiency anaemia

Iron deficiency anaemia is frequently observed in male adults and postmenopausal women due to chronic occult bleeding, usually from the gastrointestinal tract. Practically, as endoscopical investigation of the gastrointestinal system is an invasive procedure, iron replacement treatment was generally started without investigation of the underlying aetiology even in first-line health institutions. This study evaluates the role of endoscopy in the investigation of the aetiology of anaemia in 95 patients (51 males, 44 females), aged 64.9+/-12.5 years (range 50-90 years). All patients having iron deficiency anaemia were investigated by upper gastrointestinal endoscopy and colonoscopy. Upper and lower gastrointestinal pathologies were seen in 10 (10.6%) and 55 (57.8%) patients, respectively. However, no gastrointestinal lesion was found in 30 (31.6%) patients with iron deficiency anaemia. Out of the 95 patients, 16 (16.9%) had erosive gastritis, 15 (15.8%) duodenal ulcer, 8 (8.4%) gastric ulcer, 7 (7.3%) gastric tumours, 7 (7.3%) oesophagitis. 5 (5.4%) colon tumours, 3 (3.2%) haemorrhoids, 2 (2.1%) non-tropical sprue, 1 (1%) colonic polyp, and 1 (1%) colitis. In the majority of elderly patients with iron deficiency anaemia, upper gastrointestinal system disease was found. In 12 (12.7%) patients in the study group, malignancies were detected. In elderly patients with iron deficiency anaemia, the aetiology should be highlighted before giving iron supplementation.
