The Relation between the Color M‐Mode Propagation Velocity of the Descending Aorta and Coronary and Carotid Atherosclerosis and Flow‐Mediated Dilatation

Background: To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Common carotid intima‐media thickness (CIMT) and brachial artery flow‐mediated dilatation (FMD) have correlated with coronary atherosclerosis. Recently, the color M‐mode‐derived propagation velocity of descending thoracic aorta (AVP) was shown to be associated with coronary artery disease (CAD). Methods: CIMT, FMD, and AVP were measured in 92 patients with CAD and 70 patients having normal coronary arteries (NCA) detected by coronary angiography. Patients with acute myocardial infarction, renal failure or hepatic failure, aneurysm of aorta, severe valvular heart disease, left ventricular ejection fraction <40%, atrial fibrillation, frequent premature beats, left bundle branch block, and inadequate echocardiographic image quality were excluded. Results: Compared to patients with normal coronary arteries, patients having CAD had significantly lower AVP (29.9 ± 8.1 vs. 47.5 ± 16.8 cm/sec, P < 0.001) and FMD (5.3 ± 1.9 vs. 11.4 ± 5.8%, P < 0.001) and higher CIMT (0.94 ± 0.05 vs. 0.83 ± 0.14 mm, P < 0.001) measurements. There were significant correlations between AVP and CIMT (r =−0.691, P < 0.001), AVP and FMD (r = 0.514, P < 0.001) and FMD and CIMT (r =−0.530, P < 0.001). Conclusions: The transthoracic echocardiographic determination of the color M‐mode propagation velocity of the descending aorta is a simple practical method and correlates well with the presence of carotid and coronary atherosclerosis and brachial endothelial function.

Extrinsic allergic alveolitis. Apropos of a severe case

A case of atypical extrinsic allergic alveolitis in a 13-year-old is reported. Onset was sudden with gradually increasing dyspnea on exertion over a four-day period. The chest film evidenced a reticulonodular syndrome with decreased respiratory movements. The patient's clinical status worsened over the next 48 hours with the development of respiratory distress. Under oxygen therapy (3 l/min), PO2 was 49 mmHg and SO2 was 82%. Dramatic improvement occurred after initiation of corticosteroid and antimicrobial therapy. Etiologic investigations were negative except for the immunofluorescence test with pigeon droppings which showed three precipitation arcs. A CT scan of the chest disclosed diffuse micronodular densities without thickening of connective tissue trabeculae, suggesting alveolar disease. Mediastinal lymph nodes were not enlarged. Vital capacity was 26% of the theoric value. Corticosteroids were given for one month. On follow-up chest films, the reticulomicronodular syndrome was seen to abate, globally at first, then from the apices to the bases of the lungs. However, a repeat CT scan at the 4th month showed that diffuse lesions were still present although the chest film was normal; 8 months after onset, there was only a bulla in the left lung base, with no evidence of fibrosis. Lung function tests slowly returned to normal, as did CT scan findings.     

Balanced orbital decompression in Graves' orbitopathy: Upper eyelid crease incision for extended lateral wall decompression

INTRODUCTION. This study reports on the results and complications detected in patients with Graves' orbitopathy who underwent balanced medial and lateral wall orbital decompression through concealed incisions. MATERIALS AND METHODS. The medial and lateral orbital walls of nine consecutive patients (14 eyes) were removed. A transnasal endoscopic spheno-ethmoidectomy was performed for the medial wall decompression. A lateral wall decompression was performed via an upper eyelid crease incision which was extended laterally in a relaxed skin tension line. The lateral aspect of the orbit was sculpted with a high-speed surgical drill from the inferior orbital fissure inferiorly and frontal bone of the lacrimal fossa superiorly to the orbital apex posteriorly, including the thick bone of the greater wing of the sphenoid. RESULTS. The decompression was performed for cosmetic purposes in seven patients (10 orbits) and for exposure keratopathy and restrictive myopathy in the remaining two patients (4 orbits). The average follow-up period was 13.6 months. The mean reduction of proptosis was 4.8 mm. The preoperative diplopia in two cases demonstrating restrictive myopathy worsened during the postoperative period. New onset diplopia was not detected in seven cases operated on for cosmetic purposes. All patients were satisfied with their eye status, visual rehabilitation and cosmetic appearance. CONCLUSIONS. The transnasal endoscopic approach for medial wall and extended lateral wall decompression with hidden eyelid crease incision provides a favorable cosmetic and physiologic outcome with proper retroplacement of the globe.     

Laparoscopic repair of congenital diaphragmatic hernias

Bochdalek and Morgagni hernias are the least common congenital diaphragmatic hernias, with the prevalence of Bochdalek hernia being 1/2200 births and the prevalence of Morgagni hernia being 1/1 million births. Although they are usually asymptomatic, congenital diaphragmatic hernias, especially Bochdalek and Morgagni hernias, are diagnosed in early childhood. In adulthood, they are diagnosed incidentally or when they become symptomatic. The repair of congenital diaphragmatic hernia is indicated in all children and symptomatic adults. We present three cases of congenital diaphragmatic hernia, two Morgagni and one Bochdalek hernias, repaired laparoscopically. We describe the operational methods. The results of the operations were satisfactory, with cure defined with radiological images after 1 month. We propose the use of laparoscopy in the repair procedure because it is a safe and effective method. Benefits include that it provides an excellent view of the surgical field, ease of execution, minimal surgical trauma, excellent cosmetic results, rapid recovery, and shorter hospitalization stay.     

Anthropometric measurements in male breast cancer

Background: 1% of breast cancers occur in men.The etiology is obscure. An elevated BMI has been postulated to be a cause. Methods: All male breast cancer patients operated from January 1990 to May 2001 were retrospectively reviewed. Relation between BMI and male breast cancer was examined. Results: 43 males underwent breast surgery for breast cancer during this period. 3 patients were excluded from the study because of other risk factors for breast cancer.The average BMI of 40 patients was 26.54 kg/m², which is mildly above the level for normal weight. Conclusions: Excessive adipose tissue may increase risk of male breast cancer.     

Efficacy of citalopram and moclobemide in patients with social phobia: some preliminary findings

The efficacy of irreversible and reversible monoamine oxidase inhibitors (MAOIs) in the treatment of social phobia (SP) is well established. Recently, selective serotonin reuptake inhibitors (SSRIs) have been used more frequently. In the present study, the efficacy and side-effect profile of citalopram, an SSRI, and moclobemide, the only MAOI used in Turkey, were compared. The 71 patients diagnosed with SP according to DSM-III-R were randomly assigned to two subgroups; citalopram (n = 36) or moclobemide (n = 35). The study was an 8-week, randomized, open-label, rater-blinded, parallel-group trial. All patients were assessed by Hamilton anxiety rating (HAM-A), Liebowitz social anxiety (LSAS), clinical global impression-severity of illness (CGI-SI) and clinical global impression-improvement (CGI-I) scales. There was a similar percentage of responders (citalopram 75%, n = 27 and moclobemide 74.3%, n = 26), with a >50% or greater reduction in LSAS total score and ratings of "very much" or "much improved" on the CGI-I. None of the patients withdrew from the study. The results of the present study suggest that citalopram has shown promising results in patients with SP.     

Is the Cell Death in Mesial Temporal Sclerosis Apoptotic?

PURPOSE: Mesial temporal sclerosis (MTS) is characterized by neuronal loss in the hippocampus. Studies on experimental models and patients with intractable epilepsy suggest that apoptosis may be involved in neuronal death induced by recurrent seizures. METHODS: We searched evidence for apoptotic cell death in temporal lobes resected from drug-resistant epilepsy patients with MTS by using the terminal deoxynucleotidyl transferase (TdT) and digoxigenin-11-dUTP (TUNEL) method and immunohistochemistry for Bcl-2, Bax, and caspase-cleaved actin fragment, fractin. The temporal lobe specimens were obtained from 15 patients (six women and nine men; mean age, 29 +/- 8 years). RESULTS: Unlike that in normal adult brain, we observed Bcl-2 immunoreactivity in some of the remaining neurons dispersed throughout the hippocampus proper as well as in most of the reactive astroglia. Bax immunopositivity was increased in almost all neurons. Fractin immunostaining, an indicator of caspase activity, was detected in approximately 10% of these neurons. Despite increased Bax expression and activation of caspases, we could not find evidence for DNA fragmentation by TUNEL staining. We also could not detect typical apoptotic changes in nuclear morphology by Hoechst-33258 or hematoxylin counterstaining. CONCLUSIONS: These data suggest that either apoptosis is not involved in cell loss in MTS, or a very slow rate of cell demise may have precluded detecting TUNEL-positive neurons dying through apoptosis. Increased Bax expression and activation of caspases support the latter possibility.
