Recruitment maneuver and high PEEP in a patient with severe reperfusion pulmonary edema after pulmonary thromboendarterectomy

Recently open lung approach such as recruitment maneuver and high PEEP has been applied in patients with acute respiratory distress syndrome. We report here a 29-year-old man with chronic pulmonary thromboembolism (CPTE). In this case, recruitment maneuver and high PEEP relieved postoperative respiratory failure. The major complications after pulmonary thromboendarterectomy (PTE) for CPTE are: reperfusion pulmonary edema (RPE), pulmonary hypertension (PH), hypoxia and bronchial bleeding, all of which the patient has demonstrated. Preoperative examination showed high pulmonary artery pressure (85/41, mean 50 mmHg), and high pulmonary vascular resistance predicted poor postoperative course. After PTE, he developed severe RPE, PH, hypoxia and bronchial bleeding, resulting in failed weaning from cardiopulmonary bypass. Therefore he required mechanical support of percutaneous cardiopulmonary support (PCPS). In ICU we repeated recruitment maneuver (PEEP: 30 cmH2O, peak inspiratory pressure: 42 cmH2O, respiratory rate; 15 breaths.min-1, for 1 min) and kept high PEEP (15 cmH2O). After initiating this ventilatory strategy, RPE was gradually relieved, followed by improvement of oxygenation and PH. We successfully weaned him from PCPS 38 hr after surgery and he was discharged alive on the 90 post-operative day. We conclude that recruitment maneuver and high PEEP may be useful for RPE developed after PTE.     

Clinical studies on TUR-P using clinical path: report of 50 cases and review of literature

PURPOSE: This study was undertaken to clarify the usefulness and problems involved in the clinical path of transurethral prostatectomy (TUR-P) in hospital. PATIENTS AND METHODS: The subjects consisted of 50 patients, for whom the Department of Urology, Jikei Medical University Hospital introduced its own clinical path and performed TUR-P during a period of 9 months from July 1999 to March 2000. The mean length of hospital stay, rate of postoperative complications, and the medical insurance claims made by these patients were clarified and compared with those of 73 patients before introduction of the clinical path. RESULTS: With the introduction of the clinical path, the length of hospital stay decreased by an average of 3.4 days and the total medical insurance claims decreased by an average of 18.5%. The rate of postoperative complications before and after introduction was almost equal. CONCLUSION: Our clinical path for TUR-P was well accepted by both patients and comedicals. However, the present medical treatment system in Japan is not as yet prepared to promote the introduction of this clinical path, and it will take some time before this clinical path is introduced on a full scale.     

Tuberculous abdominal aortic pseudoaneurysm penetrating the left psoas muscle after BCG therapy for bladder cancer

We describe a case of a 75-year-old man with abdominal aortic and right femoral tuberculous pseudoaneurysms 32 months after intravesical bacillus Calmette-Guerin therapy for bladder cancer. These aneurysms were probably brought on by systemic infection by Mycobacterium bovis. The infrarenal aorta and right common femoral artery were successfully replaced with an in situ expanded polytetrafluoroethylene graft.Tuberculous pseudoaneurysm after bacillus Calmette-Guerin therapy for malignancy is very rare, and we review the related literature.     

Ascending Colon Cancer with Hepatic Metastasis and Cholecystolithiasis in a Patient with Situs Inversus Totalis Without Any Expression of UVRAG mRNA: Report of a Case

Situs inversus totalis refers to an inverted position of part or all of the viscera, which represents a mirror-image of the normal location, and it is a relatively rare condition that occurs in one in 4000–8000 people in Japan. We herein report a patient demonstrating a combination of situs inversus totalis, colon cancer with hepatic metastasis, and cholecystolithiasis, who was treated surgically. We found no expression of UVRAG mRNA in our case, thus suggesting that the UVRAG gene is partly responsible for this condition.     

Body iron stores and iron restoration rate in Japanese patients with chronic hepatitis C as measured during therapeutic iron removal revealed neither increased body iron stores nor effects of C282Y and H63D mutations on iron indices

Information on the level of iron stores in chronic hepatitis C is clinically important because its reduction is technically simple and therapeutically effective. This study was performed to measure the levels of iron stores from the total amounts of hemoglobin removed during iron reduction therapy. The C282Y and H63D mutations of HFE gene were analyzed in 94 patients. All of the patients were negative for C282Y mutation. One patient was homozygous, and 4 patients were heterozygous for H63D mutation. The body iron stores and iron restoration rate were measured in 59 patients in serial courses of iron reduction therapy. Mean values of body iron stores in the two groups with and without H63D mutation were 890 and 606 mg, while those of iron restoration rate were 1.85 and 1.52 mg/day, respectively. None of the indices of iron metabolism were different from the reference values measured similarly in healthy subjects, suggesting that the iron deposition in chronic hepatitis C is limited to the liver, probably due to changes in the iron distribution in tissues.     

Effects of phosphodiesterase inhibitors after coronary artery bypass grafting

The aim of this study was to estimate the postoperative effects of phosphodiesterase (PDE) inhibitors (milrinone and olprinone) after coronary artery bypass grafting (CABG). To prevent hypotension caused by the PDE inhibitors, low dose of catecholamines were used concomitantly. A total of 34 elective CABG cases were tested. In 12 cases, 0.25 microg kg(-1) min(-1) of milrinone, 3 microg kg(-1) min(-1) of dobutamine (DOB) and dopamine (DOA) were used concomitantly (Group-M). In another 10 patients, 0.1 microg kg(-1) min(-1) of olprinone and the same doses of the catecholamines were infused (Group-O). As a control, the same doses of DOA and DOB only were administered in 12 patients (Group-C). When the pump flow of the cardiopulmonary bypass (CPB) decreased to half, these drugs were given in all groups. Hemodynamics were recorded before CPB, just after the operation, and 3, 6, 12, 24, 48 and 72 h after the operation. Both milrinone and olprinone increased the cardiac index and decreased systemic vascular resistance to almost the same degree. Olprinone decreased mean aortic and pulmonary artery pressures, and also significantly reduced the preload of both right and left heart compared with milrinone. Significant hypotension was not detected due to the concomitant usage of low-dose catecholamines. This concomitant usage of PDE inhibitors and catecholamines allowed easy weaning from CPB, demonstrating excellent hemodynamics after CABG. Good oxygen demand and supply balance were maintained in peripheral tissue. These results suggest that these new PDE inhibitors may be effective not only for weaning from CPB but also for post-cardiotomy cardiogenic shock.     

Does maternal employment affect breast-feeding?

A prospective survey of maternal employment and breast-feeding initiation and duration was conducted among 668 Black and 511 White women who delivered their first child in Washington, DC. Ninety-one percent of White women (n = 511) and 80 percent of Black women (n = 668) reported working during pregnancy. Black women who planned to return to work part time vs full time were more likely to breast-feed rather than formula-feed (adjusted odds ratio, 2.3; 95% confidence intervals (CI) = 1.4, 3.7). Using Cox regression, Black women who returned to work had a shorter duration of breast-feeding than those not returning to work (hazard ratio = 0.5 (CI = 0.3, 0.9]. Black and White women returning to professional occupations had a longer duration of breast-feeding compared to women returning to sales or technical positions (hazard ratio for Black women = 2.4 (CI = 1.4, 44); hazard ratio for White women = 1.6 (CI = 1.0, 2.5]. In addition, White women in professional occupations had a longer duration of breast-feeding than women in clerical positions (hazard ratio = 1.7 (CI = 1.1, 2.6]. Until employers in the United States develop a maternity policy which does not discourage breast-feeding, the recommended six months of breast-feeding will be difficult to achieve for most employed women.     

Temporary corneal oedema after acute intake of alcohol.

A 65-year-old man had diffuse, bilateral corneal oedema after acute intake of alcohol. Three days later the total opacification began to clear from the peripheral area towards the centre of the cornea. One month later both corneas were completely clear, and visual acuity was 20/20 in both eyes. Specular microscopy showed in the right eye greatly enlarged endothelial cells, which subsequently shrank, and they showed some pleomorphism six months later. The pleomorphic endothelial cells in the left eye changed little with time. Our findings suggested that the corneal oedema in this patient resulted from temporary endothelial dysfunction with extensive cell loss.
