The association between the Holocaust experience and suicide has rarely been studied systematically. The dearth of data in this area of old-age psychiatry does not necessarily imply that Holocaust survivors are immune from suicide. Recent work on the aging of survivors seems to suggest that as a group they are at high risk for self-harm. Published reports on suicide and the Holocaust identified by means of a MEDLINE literature search were reviewed. A similar search was performed on the Internet using the Google search engine. Thirteen studies were uncovered, 9 of which addressed the association of suicide and the Holocaust experience and 4 focused on the suicide within the concentration camps during the genocide. Eleven of the 15 studies explicitly reported on the association of suicide, suicidal ideation or death by suicide with the Holocaust experience, or reported findings suggesting such an association. The Internet search yielded three sites clearly describing increased suicide rates in the concentration camps. An increased rate of suicidal ideation and suicide attempts among the elderly who were exposed to the Holocaust experience is confirmed. There is a need for further study, intervention and resource allocation among the growing numbers of elderly persons who suffered traumatic events in earlier phases of their lives. This is especially critical for Holocaust survivors.

Rembrandt van Rijn (1606–1669) left behind the largest collection of self-portraits in the history of art. These portraits were painted over a period of 41 years, using a realistic technique. To evaluate Rembrandt's aging process we studied 25 uncontested Rembrandt oil self-portraits by means of objective and descriptive techniques. By measuring brow position changes through the years, we demonstrated that brow descent started in the second half of the third decade and began to level out in the fourth decade. Based on Rembrandts' aging physiognomy, from age 22 to 63, we believe that Rembrandt did not suffer from temporal arteritis, hypothyroidism, rosacea, or rhynophima and that no other facial signs of systemic diseases are evident, contrary to the opinions expressed by other medical professionals. We suggest that Rembrandt suffered from melancholia or mild depression, and propose the possibility of chronic lead poisoning as a theoretical illness that he might have had.

Background: Testicular torsion associated with undescended testis is uncommon but requires immediate treatment. Ultrasound Doppler is recognized as the preferred imaging modality for testicular torsion due to its high specificity, sensitivity and availability.

Objectives: To determine the accuracy of ultrasound Doppler in diagnosis of torsion of undescended testis.

Methods: We describe three patients with known undescended testis who were admitted with groin pain and had preoperative ultrasound Doppler. The discrepancy between these and the intraoperative findings is discussed.

Results: In two patients incarcerated inguinal hernia was diagnosed with ultrasound Doppler; however, surgery revealed torsion of an undescended testis. In the third patient ultrasound Doppler diagnosed torsion of undescended testis, but at surgery incarcerated inguinal hernia was found, without evidence of testicular torsion.

Conclusions: Torsion of undescended testis should be a clinical rather than radiologic diagnosis.
 

Objectives: To determine whether there is an association between the presence and severity of adult calcific aortic stenosis and Chlamydia pneumoniae seropositivity

Methods: Forty adult patients (23 women, 17 men) were divided into three groups according to echocardiographic aortic valve area: Group A – 7 symptomatic subjects (age 67 ± 7 years) with normal aortic valve and normal coronary angiogram, Group B – 16 patients (age 73 ± 6) with moderate ACAS[1] (AVA[2]> 0.8 £ 1.5 cm²), and Group C – 17 patients (age 76 ± 7) with severe ACAS (AVA £ 0.8 cm²). We tested for immunoglobulins M, G and A as retrospective evidence of C. pneumoniae infection using the micro-immunofluorescence method. Past C. pneumoniae infection was defined by IgG titer > 16 £ 512.

Results: No patients in Group A showed positive Ig[3] for C. pneumoniae. IgM was not detected in any of the patients with ACAS (groups B and C) while 2 of 17 patients (12%) in group C showed IgA for the pathogen. High titers of IgG were found in 14 of 33 (42%) of the patients with moderate or severe ACAS: 5 of 16 (31%) in group B and 9 of 17 (53%) in group C (P = 0.2). Both groups had the same prevalence of coronary artery disease (66%). AVA was lower in IgG-seropositive patients than in the seronegative group (0.88 ± 0.3 cm² vs. 1.22 ± 0.4 cm², respectively, P = 0.02).

Conclusions: Past C. pneumoniae infection may be associated with a higher prevalence and greater severity of ACAS.

Background: The current methods for pre‑ and post‑chemotherapy examination of the extent of disease in the breast and lymph nodes do not provide sufficiently accurate information and, not infrequently, the surgeon has to re‑operate.

Objectives: To correlate the findings between three methods of examination (physical examination, ultrasonography, mammography), all performed by the same oncologic and radiologic team, in patients with locally advanced breast cancer or a tumor/breast tissue ratio that precludes breast-conserving surgery.

Methods: Forty patients (median age 48 years, range 24–73) with locally advanced breast cancer or with a tumor/breast ratio that precluded breast‑conserving surgery were evaluated by the same medical team and received neoadjuvant chemotherapy. Surgery was performed in all, and the pathologic specimen was correlated with the results of the other examinations.

Results: In the pre‑chemotherapy evaluation, the imaging findings of the breast correlated with the physical findings in 78% of the patients and with the axilla examination in 66.7%. In the post‑chemotherapy analysis, imaging agreed with the physical findings of the breast in 62.2% and in 76.3% of the axilla. Sonography best detected occult breast disease and axillary lymph nodes but correlated with pathology in only 58% of the patients in diagnosing breast tumor and in 65.8% in diagnosing axillary lymph nodes. Mammography correlated with breast and lymph node pathology in half the patients.

Conclusions: None of the classical methods of post‑neoadjuvant chemotherapy evaluations could adequately delineate the actual extent of the disease in the breast and axillary lymph nodes. More exacting techniques of imaging combined with the classical methods are required.

Background: Magnetic resonance imaging is a diagnostic tool of growing importance. Since its introduction, certain medical implants, e.g., pacemakers, were considered an absolute contraindication, mainly due to the presence of ferromagnetic components and the potential for electromagnetic interference. Patients with such implants were therefore prevented from entering MRI systems and not studied by this modality. These devices are now smaller and have improved electromechanical interference protection. Recently in vitro and in vivo data showed that these devices may be scanned safely in the MRI.

Objectives: To report our initial experience with three patients with pacemakers who underwent cerebral MRI studies.

Methods: The study included patients with clear clinical indications for MRI examination and who had implanted devices shown to be safe by in vitro and in vivo animal testing. In each patient the pacemaker was programmed to pacing-off. During the scan, continuous electrocardiographic telemetry, breathing rate, pulse oximetry and symptoms were monitored. Specific absorption rate was limited to 4.0 W/kg for all sequences. Device parameters were assessed before, immediately after MRI, and 1 week later.

Results: None of the patients was pacemaker dependent. During the MRI study, no device movement was felt by the patients and no episodes of inappropriate inhibition or rapid activation of pacing were observed during the scan. At device interrogation here were no significant differences in device parameters pre-, post-, and 1 week after MRI. Image quality was unremarkable in all imaging sequences used and was not influenced by the presence of the pacemaker.

Conclusion: Given appropriate precautions, MRI can be safely performed in patients with a selected permanent pacemaker. This may have significant implications for current MRI contraindications.  

Objectives: To establish the impact of breast MRI on women undergoing testing in our institution.

Methods: We analyzed 82 cases that underwent MRI between January 2001 and April 2003. Analysis appraised the clinical impact of MRI testing in cases where medical summaries were available.

Results: Studies were categorized into five indications: a) screening in high risk women (n=7), b) search for primary disease in the presence of disease (n=5), c) monitoring of chemotherapy (n=2), d) postoperative assessment of tumor bed (n=9), and e) diagnostic/characterization of primary or recurrent breast cancer (n=59). Results were defined as negative, positive or no impact on clinical management. MRI testing had a positive impact in 62 cases, affecting measurable change in 9 cases. Benefit was seen in screening, diagnosis and postoperative cases. In 15 cases, MRI stimulated investigations.

Conclusion: MRI is a valuable tool in breast imaging and affects management. Further trials are necessary to define clearly the role of MRI and to ascertain whether in cases where beneficial impact on management is noted, there is ultimate impact on outcome. 

Objectives: To compare the subjective visibility of normal anatomic landmarks in the chest on storage phosphor-based digital radiographs versus conventional screen-film radiographs.

Methods: Digital phosphor-based and screen-film posteroanterior chest radiographs were obtained during 1 year in 140 asymptomatic patients without any known pulmonary disease (119 men, 21 women; mean age 52.1 years, range 23–86). Both sets of films were independently compared by two experienced radiologists in different sessions. The visibility of each of the following anatomic landmarks was graded from 1 to 3: pulmonary fissures, carina, bronchi to left upper lobe, right upper lobe and left lower lobe, bronchus intermedius, anterior and posterior junctional lines, and vessels behind the heart and diaphragm. Additionally, subjective general quality impression of each radiograph was graded similarly. Statistical analyses were performed using the chi-square test. A P value less than 0.05 was considered significant.

Results: Visibility with the digital images was statistically significantly higher for the carina, left lower lobe bronchus, bronchus intermedius, and vessels behind the heart and diaphragm. Subjective general quality impression of digital radiographs was also higher (P < 0.001). No significant visibility differences were found for pulmonary fissures or junctional lines.

Conclusion: Subjective visibility of anatomic structures behind the heart and diaphragm and at the hilae is significantly improved with phosphor-based digital radiography compared with conventional screen-film radiography. This suggests that pathologic processes such as pulmonary nodules, masses or consolidations projected over those structures may be more easily and reliably depicted on digital than conventional chest X-rays.

Objectives: To investigate the spectrum of findings in 32 consecutive patients with chest pain who underwent CT coronary angiogram in order to determine the clinical situations that will benefit most from this new technique.

Methods: Thirty-two patients with chest pain were studied by MDCT[1] using 4 x 1 mm cross-sections, at 500 msec rotation with pitch 1–1.5, intravenous non-ionic contrast agent and a retrospectively ECG-gated reconstruction algorithm. The heart anatomy was evaluated using multi-planar reconstructions in the axial, long and short heart axes planes. Coronary arteries were evaluated using dedicated coronary software and the results were compared to those of the conventional coronary angiograms in 12 patients. The patients were divided into four groups according to the indication for the study: group A – patients with high probability for coronary disease; group B – patients after CCA[2] with undetermined diagnosis; group C – patients after cardiac surgery with possible anatomic derangement; and group D – symptomatic patients after coronary artery bypass graft, before considering conventional coronary angiography.

Results: Artifacts caused by coronary motion, heavy calcification and a lumen diameter smaller than 2 mm were the most frequent reasons for non-evaluable arteries. Assessment was satisfactory in 83% of all coronary segments. The overall sensitivity of 50% stenosis was 74% (85% for main vessels) with a specificity of 96%. Overall, the CTCA[3] results were critical for management in 18 patients.

Conclusions: Our preliminary experience suggests that CTCA is a reliable and promising technique for the detection of coronary artery stenosis as well as for a variety of additional cardiac and coronary structural abnormalities.

Objective: To investigate the effectiveness of preoperative chemoradiation in increasing the resectability rates of rectal cancer and increasing the anal sphincter preservation rate.

Methods: The study group included 66 patients aged 33–84 years with T₂–T₃ rectal carcinoma who were treated in our institute from 1997 to 2002 with preoperative chemoradiation followed by surgery 6 weeks later. All patients underwent preoperative transrectal endoscopic ultrasound for tumor staging and localization. The duration of follow-up was 25 months.

Results: Chemoradiation led to tumor downstaging in 61 patients (92.4%), all of whom underwent low anterior resection. Only 11.4% of this group needed a temporary (6 weeks) loop colostomy/ileostomy. None of the 16 patients with post-treatment T₀ tumors had evidence of malignant cells on pathologic study. Five patients (7.6%) failed to respond to chemoradiation and underwent APR[1]. There were no major complications, such as leakage, and no deaths.

Conclusions: Neoadjuvant chemoradiation is an effective modality to downstage advanced rectal cancer, improving patient quality of life by significantly reducing the need for a terminal permanent colostomy, or even a temporary one.
