Peculiar clinical features of cellulitis in peripheral lymphedema.

Although the occurrence of cellulitis in lymphedema (LE) is believed to be an infection-related event, many findings in its clinical course seem to suggest that it is unlikely to be an infection. Therefore, we tried to clarify the specific features of cellulitis in LE. In-hospital courses of cellulitis obtained from medical charts were reviewed in the patients with leg LE (LE; 24 patients, 72admissions), chronic venous insufficiency (CVI; 28 patients, 29 admissions), and leg cellulitis secondary to wound infection without underlying disease (N; 42 patients, 42 admissions). The patients with LE complained of less local pain (peak numerical scale; LE: 1.4 ± 1.7, CVI: 4.1 ± 2.5, N: 3.2 ±2.0, p < 0.0001), showed an abnormally higher peak procalcitonin level (LE: 33.8 ± 34.8 (N = 7), CVI: 2.9 ± 5.8 (N = 8), N: 0.4 ± 0.6(N = 10), p < 0.05), and required fewer antibiotics (LE: 1.1 ± 0.3, CVI: 1.8 ± 0.9, N: 1.5 ± 0.9, p < 0.0001). These findings suggested that the occurrence of cellulitis in LE seems unlikely to be an infection-related type of cellulitis similar to that found in CVI.

Effect of three-size too large strong stocking on venous hemodynamics in normal subjects.

OBJECTIVES: To study the differences in impact on venous hemodynamics between larger size strong graduated elastic compression stockings (GECS) and appropriate size strong/moderate GECS. METHOD: In healthy legs fitted for a small (Group S; n = 8) and large (Group L; n = 8) GECS, air plethysmography was performed without GECS, with an appropriate size strong GECS (GECS1), with a three-size too large strong GECS (GECS2), and with an appropriate size moderate GECS (GECS3) in this order. RESULTS: In Group S, interface pressure with GECS2 was equal to or higher than that with GECS3. Decreased venous volume, unchanged ejection volume, and decreased residual volume were achieved by GECS, but differences in these parameters among GECS were not observed. Although insignificant, a similar tendency was found in Group L. CONCLUSIONS: A larger size strong GECS seemed to have equivalent interface pressure and impact on venous hemodynamics compared to an appropriate size moderate or strong GECS.

Study on different bandages and application techniques for achieving stiffer compression.

OBJECTIVES: The objective of this study was to investigate the relationship between interface pressure and stiffness of compression achieved by various combinations of bandages and application techniques. METHOD: There were eight healthy volunteers. One roll (4.5 m) of four types of bandages with different extensibilities (0, 90, 108 and 218%) was applied to the leg in single-layer bandage fashion with eight random tensions. Then, the leg was wrapped with one to eight rolls in multi-layer bandage fashion. RESULTS: Each combination of bandage and application technique displayed an indigenous linear interface pressure-static stiffness index relationship. With single-layer bandage, lower extensibility was associated with higher static stiffness index at a given interface pressure. With multi-layer bandage, the static stiffness index at a given interface pressure was independent of the bandage type. CONCLUSION: The stiffness at a given interface pressure was affected by the extensibility with single-layer bandage but not with multi-layer bandage.

[Metastatic carcinoma of the adrenal gland from large cell neuroendocrine carcinoma; report of a case].

A 69-year-old man had undertaken left upper lobectomy (ND 2 a) with partial resection of the left lower lobe under the diagnosis of a primary lung cancer, T2N0M0, stage IB in June, 2002. The histopathological diagnosis was large cell neuroendocrine carcinoma (LCNEC), T3N0M0, stage IIB. The patient was discharged on postoperative day 25. Abdominal computed tomography (CT) revealed an enhanced tumor in the left adrenal lesion, 3 cm in diameter, in October, 2003. Magnetic resonance imaging (MRI) showed a slightly low intensity mass on T1-weighted imaging and slightly high intensity on T2-weighted imaging without invasion to other organs. Tumor marker, NSE was slightly elevated on blood examination. Left adrenalectomy was performed with a surgical margin. Histopathologically, the tumor was diagnosed as metastasis of LCNEC. There is no evidence of recurrence for a year after surgery. Although a prognosis of LCNEC is poor in general, we should consider the resection of metastatic carcinoma of the adrenal gland from LCNEC for long-term survival expectantly.

Fatal diffuse atheromatous embolization following endovascular grafting for an abdominal aortic aneurysm: report of a case.

A 78-year-old woman with an abdominal aortic aneurysm, 57 mm in diameter, was admitted to our hospital for endovascular grafting. Preoperative computed tomography and angiography showed friable mural thrombus in the suprarenal and infrarenal aorta, and a diagnosis of shaggy aorta was made. Postoperatively, the patient suffered cerebral infarction, and disseminated intravascular coagulopathy with multiple organ failure developed, resulting in early death on the third day after surgery. An autopsy revealed diffuse atheromatous embolization into the celiac, superior mesenteric, bilateral renal, bilateral hypogastric (trash buttock), and peripheral arteries. This case report serves to demonstrate that an abdominal aortic aneurysm with a shaggy aorta in the proximal neck is a contraindication to endovascular grafting, and that predicting the possibility of diffuse atheromatous embolization by detecting a shaggy aorta is the best way to prevent this catastrophic complication.

Is endovascular treatment of abdominal aortic aneurysms less invasive regarding the biological responses?

To compare the biological responses following an endoluminal repair and a conventional open repair of abdominal aortic aneurysm (AAA), 14 patients who underwent an endoluminal repair (endograft group) and 26 who underwent an open repair (open group) were investigated. As markers of biological responses, interleukin-6 (IL-6) and -8 (IL-8), granulocyte elastase (GEL), white blood cell count (WBC), and serum C-reactive protein (CRP) were all measured preoperatively as well as on postoperative days (POD) 1, 3, and 6. In addition, the blood loss, duration of surgery, initial oral intake the day after surgery, and length of hospital stay were compared between both groups. The plasma levels of IL-6, GEL, CRP, and WBC were higher in the endograft group than in the open group, while the CRP, WBC, and GEL levels all peaked on POD 3. The plasma level of IL-6 remained high in the endograft group, compared with that in the open group throughout the study period. Conversely, blood loss, initial oral intake the day after surgery, and the length of hospital stay were all significantly greater in the open group than in the endograft group, although there was no significant difference in the duration of surgery between the two groups. These findings indicate that although the endoluminal repair of AAA is supposed to be less invasive, the biological responses tend to be greater because of the manipulation related to the insertion of the stent graft.

[A case of multiple primary malignant melanoma of the esophagus].

A case of multiple primary malignant melanoma of the esophagus was reported. A 66-year-old male was referred to the hospital with complaints of appetite loss and dysphagia. A barium swallow revealed two polypoidal tumors of approximate equal size, one in the lower third of esophagus and the other in the cardiac region of stomach. The tumors were shown blackish at endoscopy and biopsy yielded a histological diagnosis of malignant melanoma. Abdominal CT, abdominal ultrasonography and hepatic arteriography showed metastasis to liver and rt paracardiac lymph nodes. However, no primary lesion of malignant melanoma but esophagus was found through the preoperative clinical examination. Partial resection of the esophagus along with the proximal of stomach and the paracardiac lymph nodes was performed. Microscopically, the typical finding of junctional activity adjacent to the tumor mass was not obtained but we diagnosed as primary esophageal tumor because melanocytes were present along the basal layer of normal esophageal mucosa and groups of melanophages were found in the submucosal layer. However, we could not conclude which polypoidal tumor was the primary lesion. The patient received systemic chemotherapy postoperatively and is alive 5 months after surgery.
