Cardiac rhabdomyoma in a newborn two-dimensional echocardiographic diagnosis

Primary cardiac tumors are quite rare in the newborn period. Prior to surgery, cardiac catheterization and angiocardiography have been performed to confirm the two-dimensional echocardiographic findings. In this report a 2-day-old baby with the clinical impression of severe cyanotic congenital heart disease diagnosed by two-dimensional echocardiography as multiple rhabdomyoma and confirmed by surgery is presented. It is emphasized that two-dimensional echocardiography is a very useful technique for the diagnosis of primary cardiac tumors. By means of this method severely symptomatic newborns may be taken directly to surgery without prior cardiac catheterization, thus minimizing complications.     

The comparison of the relaxant effects of two methoxylated flavones in rat aortic rings

The vascular effect of salvigenin (6-hydroxyapigenin 6,7,4' -trimethyl ether), a natural flavone, was investigated in comparison with another flavone, 6-hydroxyluteolin 6,7,3',4' -tetramethyl ether in rat aortic rings. Cumulative addition of their increasing concentrations (10(-9)-10(-4)M) produced graded relaxations on rings precontracted with noradrenaline (10(-6) M) and KCl (40 mM). The maximal relaxations induced by flavones were similar, however, based on their pEC50 values salvigenin displayed a higher potency than 6-hydroxyluteolin 6,7,3',4'-tetramethyl ether. Endothelium removal markedly reduced the relaxations to salvigenin while the responses to 6-hydroxyluteolin 6,7,3',4'-tetramethyl ether were partially affected. In addition, a significant decrease was observed in maximal responsiveness and sensitivity to flavones in the presence of L-NOARG, a NO synthase inhibitor. The cyclooxygenase inhibitor indomethacin significantly inhibited the relaxations to salvigenin, but not altered the responses to 6-hydroxyluteolin 6,7,3',4'-tetramethyl ether. Our results provide evidence that salvigenin is an effective flavone in causing vasorelaxation which appears to be mediated by endothelium derived NO and prostacyclin. Whereas, the other flavone, 6-hydroxyluteolin 6,7,3',4'-tetramethyl ether induced relaxant responses are partially endothelium, presumably NO mediated.     

A magnificent circumcision carnival in the early 18th century Ottoman period

Circumcision has always been regarded as both an important social event and a milestone of a young man's life in Turkish culture, especially in the Ottoman period. Herein we study an exceptional circumcision festivity which lasted 15 days in the early autumn of the year 1720, for the 4 princes of Sultan III Ahmed, some sons of two high-ranking Ottoman officials and thousands of male children of poor citizens of Istanbul as representing the beneficent of the Sultan. All the organizations of the Empire participated in this huge event, including many shows and a feast, and the preparations were initiated months before. Traditionally, this kind of important social event of Ottoman culture had been described in a literary manner, and Surname-i Vehbi was the special name for the book of this circumcision festivity with 137 colored paintings and a total of 175 pages. The original of this work, which is in the library of Topkapi Palace Museum in Istanbul, was written by Vehbi and illustrated by Levni. The importance of this antique book is that it is the last important example of the illustrated festivity books of Ottoman literature.     

Brachioradialis transposition for elbow extension in obstetrical brachial plexus palsy

Disorders of elbow extension occur following traumatic or neurologic injuries of the triceps muscle. Restoration of elbow extension is an integral part of the entire upper extremity surgical reconstruction to improve the following daily activities: bringing down an object from above, handwriting, using the hand in the supine position, steering a wheelchair, driving a car, and swimming. The transfer of the posterior head of the deltoid muscle to triceps (Moberg procedure) and the transfer of the biceps to triceps (Friedenberg procedure) are previously described procedures for the functional restoration of triceps function. In conditions where these procedures cannot be used, we describe a new technique for restoration of elbow extension. In 4 cases with obstetrical palsy sequela, where shoulder abduction was established with the latissimus dorsi and teres major transfer, restoration of elbow extension was planned to aid in activities performed while the hand is above the head. To achieve this goal, the brachioradialis muscle was transposed bipedically to the triceps muscle.     

Autosomal dominant periodic fever with AA amyloidosis: tumor necrosis factor receptor-associated periodic syndrome (TRAPS) in a Turkish family

We investigated the presence of tumor necrosis factor receptor-associated periodic syndrome (TRAPS) in a Turkish family with recurrent fever and systemic reactive (AA) amyloidosis. A missense mutation in exon 3 of the TNFRSF1A gene, resulting in an amino acid substitution Phe60Leu (F60L) was found in the proband and his father. These are the first confirmed TRAPS cases in the Turkish population. This family highlights the importance of onsidering all the causes of inherited fevers and performing thorough clinical and genetic investigations to secure a diagnosis, even in populations in which familial Mediterranean fever (FMF) is highly prevalent.     

Mature spinal teratoma associated with thickened filum terminale

A 30-year-old man presented with an intradural spinal teratoma with thickened filum terminale manifesting as urinary and sexual disturbances, and low back pain persisting for 4 years. Spinal magnetic resonance imaging revealed thickened filum terminale containing a heterogeneously enhanced intradural lesion extending from the L-3 to L-4 levels and in contact with the conus medullaris. The filum terminale was incised and the tumor was totally resected. The histological diagnosis was mature teratoma consisting of three germ cell layers. The patient's complaints had completely resolved 6 months later.     

Proliferating-cell nuclear antigen (PCNA) as an independent prognostic marker in patients after prostatectomy: a comparison of PCNA and Ki-67

OBJECTIVE: To investigate the prognostic value of prostatic tumour cell proliferation, as measured by Ki-67 and proliferating cell nuclear antigen (PCNA), and to compare these measures in men at low and high risk for progression of tumour. PATIENTS AND METHODS: Two groups of patients with prostate cancer, i.e. 'metastatic' (M, 22) who had pT3b-4aN0M0 and pTanyN1M0, and 'nonmetastatic' (NM, 18), who had < or =pT3aN0M0 disease, were selected from a well-examined and mapped group of 114 treated by radical prostatectomy. Patients in the NM group were selected by the criteria of having a Gleason score of < or = 7. To assess proliferation, 1000 cells were counted at x 400 magnification by two observers and the percentage of tumour cells positively stained with Ki-67 and PCNA defined as the Ki-67 and PCNA labelling index (LI), respectively. The two LI were compared in the NM and M groups, and the correlation of the LIs with pathological stage, progression and prostate-specific antigen (PSA)-free survival evaluated. Prognostic values of the LI were analysed using multivariate analysis. RESULTS: The mean (range) follow-up was 33 (4-78) months. The mean LIs were higher in the M than the NM group for both PCNA and Ki-67 (P = 0.02 and 0.019, respectively). Both LIs were markedly different between the groups when stratified by progression, with both significantly higher in men with progression in the NM group. Both LIs had a significant association with Gleason score, pathological stage, progression and PSA-free survival. In multivariate analysis the PCNA LI, surgical margin status and pathological stage were independent factors for progression. CONCLUSION: Tumour cell proliferation as assessed by Ki-67 or PCNA correlate significantly with progression. The PCNA LI was an independent predictor of progression, especially in patients with a low risk of progression according to predefined criteria.     

An Assessment of the Effects of Two Types of Bioresorbable Barriers to Prevent Postoperative Intra-Abdominal Adhesions in Rats

Purpose This study assessed and compared the efficacy of two types of bioresorbable membranes in the prevention of postoperative adhesion under clean contaminated and bacterial peritonitis conditions using a cecal ligation and puncture model in rats. Methods Wistar albino rats (n = 72) were divided into six groups. Bacterial peritonitis was induced using a cecal ligation and puncture model in groups 2, 4, and 6. Groups 1, 3, and 5 served as controls for clean contaminated procedures in the absence of bacterial peritonitis. Groups 1 and 2 were the untreated clean contaminated and bacterial peritonitis groups and served as controls for the effect of the bioresorbable membranes in each condition. In groups 3 and 4, a 1.5 × 3 cm USP glycerol/sodium hyaluronate/carboxymethylcellulose membrane was wrapped around the cecal resection area and a 2 × 4 cm membrane was left under the incision. The oxidized regenerated cellulose membrane was similarly applied in groups 5 and 6. Four weeks later, the adhesions were evaluated. In addition, fibrosis and inflammation were observed histopathologically. Results Adhesion development (P = .008), fibrosis (P = .008), and inflammation (P = .0001) differed among the groups. Both materials increased adhesion formation in the bacterial peritonitis condition. Increased fibrotic activity was detected in all material-applied groups under both conditions. In addition, more inflammation was detected in the groups that received the application of a material, especially in the presence of bacterial peritonitis. Conclusion Neither material prevented adhesions in clean contaminated conditions. Moreover, they increased adhesion formation in bacterial peritonitis.     

Comparison of preoperative anxiety in reconstructive and cosmetic surgery patients

Surgery is a serious stressor and a cause of anxiety for the patients. Reconstructive surgery patients are mostly operated on because of certain functional impairment or disability; on the contrary, cosmetic surgery patients do not have any physical impairment and they are operated on because of mostly psychologic reasons. The aim of this study was to compare the anxiety levels in the reconstructive surgery patients and cosmetic surgery patients preoperatively. Thirty-two patients in the reconstructive surgery group and 30 patients in the cosmetic surgery group were included in the study. State Trait Anxiety Inventory was used to measure the anxiety levels in these 2 groups preoperatively. The 2 groups were similar in characteristics such as age, gender distribution, number of previous operations, and trait anxiety scores. Mean state anxiety scores obtained for the reconstructive surgery group was 38.0 +/- 8.7, while it was 44.2 +/- 10.79 for the cosmetic surgery group (t test, degrees of freedom = 60, P = 0.015). This study reveals that preoperative anxiety levels in the cosmetic surgery patients are higher than those of the reconstructive surgery patients. Therefore, adequate preoperative preparation for cosmetic surgery should include attempts to cope with anxiety. Anxiolytics may be used more liberally and professional psychologic assistance may be required.
