[Multiple decubitus ophthalmological operating table].

A new ophthalmological operating table is presented which is adapted to the most recent developments in microsurgery and for the treatment of the most difficult cases of vitreoretinal pathology. The head of the table is mobile in the sagittal plane, movements being effected under remote-control by the surgeon at a rate of 2 mm/sec. The same movement can be applied to a horseshoe shaped armrest, which is solidly attached around the headpiece and is adjustable for height. A respiratory shield can be attached during local anesthesia, and the table can be positioned in proclivity or declivity. During vitreoretinal surgery, the table enables rotation of the patient in ventral decubitus along a longitudinal axis, rotation being possible manually or electrically. Proclivity and declivity positions can be obtained by rotation on a transversal axis. These functions assist exchanges between ocular fluids and substances used for internal packing, as well as passage into the anterior chamber of foreign bodies in the vitreal cavity.

[Pulmonary arteriovenous fistula and lateral decubitus anoxia].

The case of a female patient with Rendu-Osler-Weber disease associated with pulmonary arterio-venous fistula localized at the apical segment of the left inferior pulmonary lobe is described. A decrease in the oxygen arterial saturation (SaO2) at adopting the left lateral decubitus position (left-lateral-decubitodeoxia) was found, as well as an increase in the anatomical venoarterial short-circuit (Qs/Qt) in the same position. The resonsible factors of such changes in SaO2 and Qs/Qt related with the body position are analyzed, and the, exceptional in these patients, finding of alteration of pulmonary mechanics is commented.

[Urethroplasty using polyglactin mesh in urethral fistula caused by decubitus ulcer of the perineum in spinal cord injuries. Apropos of 7 cases].

Seven paraplegic patients, presenting with urethro-cutaneous fistulae due to a loss 4 to 10 cm of urethral tissue, due to decubitus ulcer of the anterior perineum, were cured. Urethroplasty was performed by wrapping the urinary catheter in a resorbable polyglactin net, covered on top by a flap of a well vascularized musculocutaneous biceps femoralis flap. The follow-up of several years proved the reliability of this technique which can be perfectly applied to others kinds of urethroplasty.

[Decubitus calcifications of the soft tissues. Comparison between radiology and echography].

In the past, several obstacles hindered the study of decubitus calcifications in soft tissues--i.e., poor prognosis, difficult patients investigation due to their poor health and, finally, unsufficient information yielded by conventional radiology. However, special radiographic techniques and US (with 7.5 MHz probes) allowed satisfactory results to be obtained. US permits the more accurate definition of the site of calcifications, better demonstration of the calcifications with poor calcium content and optimal depiction of structural changes of the muscular bundles following denervation or edema and of skin trophism changes. US limitations, besides those strictly related to the method itself, are: gross calcifications with large posterior shadowing not allowing the deep layers to be investigated, the need of an extremely qualified operator and of a detailed description and, finally, the fact that the exam is long, difficult and stressful to the operator and painful to the patient. In conclusion, US provides both the surgeon and the clinician with useful information and can thus be employed as a routine test, with the additional advantage of not employing ionizing radiations.

[Foreign body decubitus: unusual cause of acute appendicitis].

The authors describe the origin and the physiopathological events in acute appendicitis. They show an uncommon case of acute appendicitis. The aetiology was an opaque radiation foreign body causing a subacute abdominal disease. At operation the authors discovered the above body free in the abdominal cavity; the appendix was not in ischemic phase but completely cut off bycecal plant. They suppose aetiology to be of a decubitus origin.

[Cardiorespiratory evaluation of midazolam and thiopental during their use in patients undergoing translumbar aortography in decubitus prone position and ASA IV].

AIMS: To verify the cardiorespiratory effects of midazolam and thiopental in ASA IV patients undergoing translumbar aortography in the decubitus prone position. METHODS: A prospective double blind study was carried out on 26 patients (mean age, 65.9 yr) allocated randomly to receive either midazolam (0.13 mg/kg) or thiopental (4 mg/kg) i.v. Without being premedicated all the patients had fentanyl 1.5 micrograms/kg i.v. and were preoxygenated with 50% oxygen before induction of anaesthesia. Blood pressure was measured by oscilometry and blood oxygenation by pulseoxymetry. RESULTS: No significant differences were found in the hemodynamic values (blood pressure, heart rate, double product) upon comparison of the two groups. Apnea was more frequent in the thiopental group 61.5% (8 out of 13 patients) than in the midazolam group 15.3% (2 out of 13 patients). Hypoxemia appeared only in the former group (61.5% of the cases). CONCLUSIONS: In patients undergoing translumbar aortography midazolam and thiopental behaved similarly with regard to hemodynamics. Midazolam produced less apnea than thiopental.

[Atypical decubitus fibroplasia: a recent entity. Apropos of a case of an adolescent girl].

Atypical decubital fibroplasia (FAD) occurs especially in elderly and physically debilited or immobilized patients. We report one observation which is peculiar due to the patient's young age and its circumstances. The painless mass is situated in hyperpressure areas (shoulder, posterior or lateral chest wall, sacrum). The lesion is situated in the deep subcutis and has ill defined limits; it is characterized by zones of fibrinoid necrosis and fibrosis and a prominent myxoid stroma. The differential diagnoses includes mesenchymatous malignant tumors and non neoplastic fibroblastic proliferations such as proliferative fasciitis and decubitus ulcer. The prominent underlying factor and the initial event contributing to its pathogenesis seems to be ischemia. Although some recurrent cases have been reported, FAD is a benign lesion whose treatment is surgical removal.

[Left ventricular diastolic dysfunction in patients with angina decubitus].

Our study population consisted of three groups: 1. 24 cases with ejection fraction (EF) > 45% in 26 patients with angina decubitus (AD) were studied as group A. 2. 20 patients had coronary artery disease without AD as group B. Group B and A were matched for age, EF and coronary artery obstructive lesions. 3. 20 cases without cardiovascular diseases as group C. Left ventriculography (LVG) was performed in these patients. The results showed that left ventricular (LV) early 1/3 filling fraction (1/3FF) was significantly reduced in group A as compared with that in group B and C (both P < 0.001). The findings suggest that patients with AD have abnormalities of LV diastolic filling. Left ventricular end diastolic pressure (LVEDP) significantly increased in patients with AD after LVG as compared with before LVG (P < 0.01). However, there was no statistically difference in LVEDP before and after LVG in both group B and C, indicating that the compliance of LV was also decreased in patients with AD. The increase of LV volume after recumbency would cause increase of LV wall tension and myocardial contraction and aggravate the LV diastolic dysfunction, resulting in a progressive increase in myocardial oxygen consumption. Therefore, we consider that on the basis of severe coronary artery obstructive lesions, LV diastolic dysfunction is a significant pathologic factor in the pathogenesis of AD.

Re-evaluation of the mechanism and treatment of angina decubitus.

30 patients with angina decubitus (AD) were studied during hospitalization. These patients were found to have severe coronary artery obstructive lesions and an increase of myocardial oxygen consumption (MOC) before the onset to AD, indicating that AD belongs to the category of effort angina. 18 patients were investigated by continuous hemodynamic monitoring. Three patients had significant increase in pulmonary artery diastolic pressure (PADP) before the onset. In the other 15 patients, PADP increased slightly in 12 and remained unchanged in 3 cases before the onset. Left ventriculography showed ejection fraction (EF) > 45% in 25 of the 27 patients. These results indicate that left ventricular (LV) systolic dysfunction is not a major factor in the pathogenesis of AD. The patients with LVEDP > 12 mmHg constituted 60% of 25 patients with EF > 45%, suggesting that these patients had obvious LV diastolic dysfunction, which may be the major factor in the pathogenesis of AD. According to the results of our treatment, beta blockers may be used as the major form of treatment in the patients with AD.

[Decubitus ulcers: evaluation of a protocol].

An evaluation of the incidence, treatment and prevention of decubitus ulcers is presented within the framework of an Internal Medicine unit. Chosen for the study from a pool of admitted hospital patients were 60 people believed to be at risk of ulceration. They were evaluated according to established criteria and they were then followed during the length of their stay. Of these 60 patients, 38 later developed lesions. Of these 38, 63.2% were admitted with ulcers and 36.8% developed their pressure sores while in the hospital. 65.3% of those ulcers healed completely during the patients stay; 7.6% actually got worse. A significant statistical risk between the appearance of ulcers and the evaluated at risk factors was not found.

[Myocutaneous flap as reliable defect coverage in high grade pelvic decubitus ulcers. Classification, therapeutic concept and presentation of personal patient sample of 16 years].

Infected pelvic pressure sores of Campbell stages IV-VII require soft tissue reconstruction, which means stable, multi-layered filling cover of the defect and reliable prophylaxis of relapse. Myocutaneous flaps meet these conditions well. Depending on the extent and the area of the sore, with predilection for the sacrum, the ischial tuberosity and the femoral trochanter, the gluteus maximus, biceps femoris and tensor fasciae latae muscles are most often used for myocutaneous flaps. Primary sutures, split skin grafts or local fasciocutaneous flaps are often sufficient treatment for smaller, superficial defects. Between 1981 and 1996, 133 patients (average age 50 years) with 212 pelvic pressure sores of all stages were treated in our clinic. After radical decubitus excision with pseudotumor technique and resection of the osseous prominences, one-stage reconstruction of solitary as well as multiple defects was performed with myocutaneous flaps in 135 cases. The postoperative general complication rate for all treatments was about 10-30%. With regard to the muscle flaps, one third healed without any problems, partial flap necrosis occurred in 6% and there was total loss of flap in 2% of all myocutaneous flaps. According to present knowledge, myocutaneous flaps seem to be the most reliable method for definitive covering of deep pelvic pressure sores, independent of the cause of the ulcer.

[A case of elderly home care after surgical treatment for gastric cancer--elderly patient with decubitus].

As the elderly population grows, the number of elderly suffering from intestinal cancer has been increasing. After surgical treatment of intestinal cancer, occasionally the quality of life (QOL) of a patient is difficult due to pain and anxiety. Especially elderly patients experience these problems more than younger patients. Recently, we have experienced a case of an elderly patient operated for gastric cancer whose going down the level of QOL and performance status (PS) were decreasing because of lower nutrition and severe infectious decubitus. But with familial cooperation, his QOL and PS have been improving with long time Home Care.
