Alveoläres Weichteilsarkom

Alveolar soft part sarcoma is a malignant soft part tumor the etiology of which has not yet been clarified. Histopathological examinations show an alveolar or pseudoglandular pattern. PAS-positive, diastase resistant intraplasmic inclusion bodies are characteristic for this tumor which occurs in the head and neck region; mainly the tongue and the orbita. Primary therapy includes total resection which can later be combined with radiotherapy or chemotherapy. The present study involves a 17 year old patient. We totally removed the tumor and then used radiotherapy. The postoperative examinations over 3 years showed neither local recurrence nor distant metastases.     

Chest wall lipoblastoma in a seven-month-old girl: a case report

Lipoblastoma is a rare benign tumor of adipose tissue seen almost always in infanthood and early childhood. It is typically located in the extremities and the trunk and less frequently in the head-neck region, mediastinum, and retroperitoneum. However, cases of pleural, thoracic wall, and pulmonary lipoblastoma have also been reported in the literature. Lipoblastoma is a tumor with good prognosis despite its potential for local invasion and rapid growth. Our patient is a 7-month-old girl who was brought to our clinic for a rapidly growing mass in the right hemithorax. With the aim of both diagnosis and treatment, the mass was removed by thoracic wall resection and the resultant defect covered with an absorbable polyglactine mesh. The excised mass was diagnosed pathologically as a benign lipoblastoma. In the postoperative period, the thorax wall was stable, and after 24 months of follow-up no recurrence was observed. In the literature, 4 types of thoracic wall lipoblastomas have been reported, but thoracic wall resection has not been applied in any benign lipoblastoma case. To the best of our knowledge, the only benign lipoblastoma case in which a thoracic wall resection was carried out, with its clinical and histopathologic specifications alongside that in the literature, is presented here for the first time.     

Effects of Antibiotics and <Emphasis Type="Italic">Saccharomyces boulardii</Emphasis> on Bacterial Translocation in Burn Injury

Purpose To investigate the effects of antibiotics and the probiotic, Saccharomyces boulardii, on indigenous microflora and bacterial translocation (BT) in burned rats.Methods Twenty-three male albino rats were divided into a sham burn group (group 1, n = 7) exposed to 21°C water, a burn + antibiotic group (group 2, n = 8), and a burn + antibiotic + S. boulardii group (group 3, n = 8) exposed to 95°C water for 10s, producing a full-thickness burn to 30% of the total body surface area. Ampicillin-sulbactam (1000mg/kg per day) was given as two doses via an orogastric feeding tube to groups 2 and 3. Saccharomyces boulardii (1mg/g body weight per day) was given as two doses via the same route to group 3. All rats were killed on the fifth day postburn and cultures of the mesenteric lymph nodes, liver, spleen, blood, and cecal contents were done.Results The incidences of BT were 0% (0/7) in group 1, 87.5% (7/8) in group 2, and 37.5% (3/8) in group 3. A significant increase in the BT incidence was found in group 2 (P 0.01), while a significant decrease was found in group 3 when compared with group 1. The total bacteria count of cecal flora was significantly lower in group 3 than in group 1 (P 0.01). The decrease in Gram-negative bacteria in the cecal flora was significant in group 3.Conclusion These results suggest that the incidence of BT in burn injury is enhanced by using an antibiotic, and that S. boulardii decreases the incidence of antibiotic-induced BT. Thus, we conclude that S. boulardii can effectively protect the intestinal ecologic equilibrium and prevent BT in burn injury victims.     

Influence of Cardiovascular Risk Factors on the Outcome of Coronary Artery Bypass Surgery

Purpose. To assess the impact of gender, age, and other cardiovascular risk factors on the outcomes of patients undergoing coronary artery bypass grafting (CABG).Methods. A total of 5?067 consecutive patients undergoing isolated CABG between 1995 and 2000 were divided into the age groups: 25–49 years, 50–59 years, 60–69 years, and 70–84 years. Data on patient age, gender, smoking, serum cholesterol, blood pressure, body mass index, diabetes, family history, morbid obesity, and renal failure were retrospectively analyzed.Results. The percentage of women aged >60 years undergoing CABG was higher than the percentage of men aged >60 years (45.6% vs 36.6%). Most of the cardiovascular risk factors, except for smoking, were favorable in women (P < 0.001). The in-hospital mortality was 2.0% in women and 1.7% in men (P = 0.409). CABG was performed on significantly more men than women, accounting for 80.7% and 19.3% of the 5?067 patients, respectively (P < 0.001). However, the incidence increased remarkably in women aged >60 years.Conclusions. The risks of CABG may vary to some degree in accordance with the major cardiovascular risk factors. The risk of operative mortality was independent of gender in this study.     

Diagnosis and Surgical Treatment of Morgagni Hernia: Report of Three Cases

Morgagni hernia is a rare congenital disorder, which is usually asymptomatic, but may cause respiratory or gastrointestinal symptoms. We reviewed the clinical findings of three patients with a Morgagni hernia, diagnosed and treated in our department between 1997 and 2000. The Morgagni hernia caused various symptoms in all three patients and surgery was performed via posterolateral thoracotomy in two, and via laparatomy in one. The hernial defect was closed by primary suturing in two patients and by synthetic mesh in one. All three patients had an uneventful postoperative recovery. We believe that the transthoracic approach is an effective way of repairing Morgagni hernia. Received: October 19, 2001 / Accepted: July 2, 2002 RID="*" ID="*" Reprint requests to: I.C.

The Effects of Melatonin on Angiogenesis and Wound Healing

Purpose The pineal gland hormone melatonin is a well-known neoroendocrine hormone. In addition to its immunomodulator effect, it also has a positive effect on monocyte, cytokine, and fibroblast proliferations, which also influence angiogenesis. This study investigated the effects of melatonin hormone on angiogenesis in wound healing on 100 Wistar-Albino rats.Methods The rats were divided into two groups. Melatonin dissolved in 0.9% NaCl was administered to the study group in a dose of 0.4mg/kg/rat per day (0.25cc/rat per day), and 0.9% NaCl to the control group in a dose of 0.25cc/rat per day. Incisions 5cm in length were made on the back skin of the rats and the wounds were closed with a skin stapler. Excisional biopsies from healing tissues were taken on the 3rd, 7th, 10th, 14th, and 21st postoperative days. Angiogenesis was evaluated in healing tissues by light and electron microscopy and by hydroxyproline level measurements.Results The commencement of neovascularization and a significant increase (P 0.05) in the number of vessels were observed at all stages of the study group but not in the control group. The tissue hydroxyproline levels were also higher in the study group than in the control group.Conclusions Melatonin may have a positive effect on both angiogenesis and wound healing.The preliminary results of this study have been published in the Turkish Journal of Surgery     

Bone age in children with nocturnal enuresis

It is widely believed that nocturnal enuresis is caused by a hereditary delay in maturation of the various organ systems. In this study, growth and bone age were investigated in enuretic children. There was a significant bone age lag in the enuretic group compared to the control subjects of similar age (8.15 ± 1.56 years vs 9.45 ± 2.17 years, p < 0.05). It has been suggested that skeletal maturation also are retarded in nocturnal enuresis; and, it may be caused by the delayed maturation in regulatory functions of the central nervous system This revised version was published online in September 2006 with corrections to the Cover Date.     

Increased P-wave dispersion a risk for atrial fibrillation in adolescents with anorexia nervosa

ABSTRACT

Studies have shown that a prolonged P-wave dispersion is a risk factor for the development of atrial fibrillation. The aim of this study was to evaluate P-wave dispersion in adolescents with anorexia nervosa at diagnosis. We evaluated electrocardiographic findings, particularly the P-wave dispersion, at initial assessment in 47 adolescents with anorexia nervosa. Comparison of P-wave dispersion between adolescents with anorexia nervosa and controls showed a statistically significant higher P-wave dispersion in patients with anorexia nervosa (72 ± 16.3 msec) when compared to the control group (43.8 ± 9.5 msec). Percent of body weight lost, lower body mass index, and higher weight loss rate in the patients with anorexia nervosa had no effect on P-wave dispersion. Due to the fact that anorexia nervosa has a high mortality rate we believe that cardiac pathologies such as atrial fibrillation must also be considered in the medical evaluation.

Serum,salivary, and tissue levels of plasminogen in familial Mediterranean fever,amyloidosis, and chronic periodontitis

1 Background

There are no published studies regarding the role of the plasminogen (PLG) system in familial Mediterranean fever (FMF), FMF‐associated secondary amyloidosis, or chronic periodontitis (CP), although recent limited data have focused on the association between FMF and chronic periodontitis. Therefore, the aim of this study was to evaluate the serum, salivary, and gingival tissue levels of PLG in patients with CP, FMF, and amyloidosis.

2 Methods

The study population included 122 patients with FMF (only FMF, and FMF and amyloidosis and 128 individuals who were systemically healthy controls. Blood and salivary samples were obtained from the cases and controls, and clinical periodontal parameters were recorded. Serum and salivary PLG levels were assessed. The gingival tissue samples of the case and control groups were analyzed histopathologically and immunohistochemically for amyloid deposition and PLG.

3 Results

The amyloidosis group had significantly more severe clinical periodontal parameters than those of the FMF and systemically healthy groups (P < 0.05). Salivary levels of PLG were significantly higher in the FMF and amyloidosis groups compared with those in the control group (P < 0.001). The FMF with periodontitis and amyloidosis with periodontitis groups had higher salivary PLG levels compared with those in the CP group. Serum and salivary PLG levels were significantly associated with the clinical periodontal parameters in the FMF group. The amyloidosis cases had hyperplasia, severe inflammation, and activation of the gingiva.

4 Conclusion

The PLG system could play an important role in inflammatory diseases, such as chronic periodontitis, FMF, and FMF‐associated secondary amyloidosis.
