RESUMEN

Single site Multiple Lymphatic-Venous Anastomoses (MLVA) provides optimal functional and cosmetic results with low complication rates in treatment of lower limb lymphedema. However, no evidence exists in literature concerning the use of this technique in treatment of peno-scrotal lymphedema. We report a case of a 44-year-old male patient who developed secondary peno-scrotal lymphedema with severe lymphorrhea, following a laser treatment for scrotal pustolosis, leading to recurrent infections and finally an established peno-scrotal lymphedema. Utilizing MLVA, a complete remission of scrotal lymphedema was achieved with significant volume reduction of the penile lymphedema. The post-operative course was uneventful with clear improvement in lymphatic flow demonstrable on lymphoscintigraphy (6 months) and no recurrence of scrotal lymphedema at 2 years follow-up. This article reports very promising results of a novel application of MLVA in the treatment of genital lymphedema and suggests that MLVA provides the possibility to shunt both superficial and deep lymphatics to improve the lymphatic drainage from the peno-scrotal area using a single surgical site.

RESUMEN

INTRODUCTION: Composite anterolateral thigh (ALT) flap with vascularized fascia lata can reconstitute patellar tendon integrity and knee soft tissue coverage in one stage. However, long-term evidence of outcomes is lacking. This work analyzes long-term functional results, compares subtotal and total reconstruction of patellar tendon, and assesses the respective function of the extensor apparatus. PATIENTS AND METHODS: Outcomes of reconstruction using 10 ALT flaps in 9 patients (age range 21-87 years) were analyzed (mean follow-up 30 ±â€¯6 months). Knee Society Scores, isometric knee extensor strength (M1-M5), and sensory recovery were evaluated, together with active range of motion and extensor lag of the reconstructed limb, compared to contralateral. RESULTS: Ten flaps were used for tendon replacement in 9 patients. Eight (80%) free flaps and 2 (20%) propeller distally based flaps were used. Complications requiring the harvest of a second flap were seen in 2 patients. All patients could return to their daily activities without the use of walking supports. Mean active ROM was 94.4° with an extensor lag of 9.4°, without a significant difference between partial and total patellar tendon reconstruction. The mean knee and functional scores of the Knee Society were 81/100 and 77/100, respectively. CONCLUSION: Composite ALT flap with fascia lata can satisfy the twofold needs of functional restoration and soft tissue coverage, thus ensuring stable results in total and subtotal knee extensor mechanism reconstruction. Distally based flaps should be carefully considered, as they lead to higher complication rates.

RESUMEN

The vascular wall is built up of a heterogeneous population of smooth muscle cells, which exhibit not only morphological distinctions but also important differences in the composition of their structural and contractile proteins. "Epithelioid" smooth muscle cells correspond to an intimal-like type and display features associated with immaturity, whereas "spindle-shaped" cells closely resemble the more typical medial smooth muscle population. We have investigated the integration of these two cell types into the vascular architecture of an in vivo wound-healing model. Stably transfected with the beta-galactosidase gene, intima- and media-like cells were injected intravenously into the chicken chorioallantoic membrane, within which superficial foci of granulation tissue had been created by thermal or chemical injury. At 24 to 72 h after injection, cells had honed in on the lesion sites and were observed in juxtaposition to the endothelial lining of the capillaries. They began to deposit laminin, thereby indicating an impending role in the formation of the vascular wall. Intima- and media-like smooth muscle cells did not differ in their capacity to associate with capillaries, and, in so doing, their biochemical lineage characteristics became indistinguishable from one another. However, intima-like cells also penetrated the adventitial and medial layers of arteries. These findings reveal vascular smooth muscle cells to possess an extraordinary degree of plasticity, being able to adapt flexibly to changes in functional demands.

RESUMEN

We determine the correlation between viremia in serum specimens, transaminase activity (ALT and AST) and histological grading in 37 patients with chronic hepatitis C. In addition we compared two PCR methods for hepatitis C virus (HCV)-RNA in serum specimens. For the histological grading we used a modified Knodell score. For detection and quantification we measured the viremia (HCV-RNA titer) with a standardized "nested primer" PCR (end-point dilution method) and the commercially available Amplicor HCV Monitor. The mean HCV-RNA and AST level was significantly higher in patients with a histologically active inflammation. In the individual patient we could not conclude from the titer of HCV-RNA on the histologic grading because of the wide range of the results. We did not find a significant difference in ALT in patients having varying histological gradings. HCV-RNA titer and transaminases (ALT and AST) did not correlate significantly. The HCV-RNA titer was significantly marked in older patients (above 40 years) and patients having sporadic hepatitis than in younger patients and patients with chronic hepatitis after drug abuse. The "nested primer" PCR (end-point dilution method) was more sensitive for detection of HCV-RNA in serum specimens than Amplicor HCV Monitor. The lack of HCV-RNA with Amplicor HCV Monitor in 12 of 37 patients (32%) did not rule out viremia. We conclude that in patients with a chronic hepatitis C marked viremia points to a histologically active inflammation. In the individual patient we could not conclude from the titer of HCV-RNA on the histological grading. Because of the lower sensitivity of Amplicor HCV Monitor it is necessary to confirm negative results with a "nested primer" PCR.

RESUMEN

The purpose of our study was to verify the correlation between biochemical and histological inflammatory activity in chronic hepatitis C. The histological activity index (HAI) of 42 patients with chronic hepatitis C was correlated with their transaminase activity. There was indeed a significant correlation between histological activity and the AST (r = 0.54, p = 0.0002) and ALT level (r = 0.36, p = 0.018) respectively. Due to considerable scatter of the results, transaminase activity did not allow reliable assessment of inflammatory activity in individual cases. In the majority, markedly elevated transaminase activity was associated with marked histological inflammatory activity, whereas normal or slightly elevated transaminase activity was found in all stages of inflammatory activity. To assess inflammatory activity in chronic hepatitis C, a liberal indication for liver biopsy should therefore be adopted.

RESUMEN

The aim of the study was to determine the frequency and course of hepatitis C viremia in clinically healthy, anti-HCV positive test subjects, and to ascertain whether the HCV antibodies of the IgM type differed between viremia and immunity. In 21 anti-HCV positive blood donors (test subjects) with normal transaminase activity, two serum samples, taken at an interval of 25 +/- 10 months, have been investigated for HCV-RNA and HCV-IgM antibodies. In a total of 16 test subjects (76%) HCV-RNA was found during the first test and/or the follow-up: 14 of them were positive on both occasions, and one test subject each was HCV-RNA positive exclusively at the first test and the follow-up respectively. At the time of the follow-up the serum transaminase level was elevated in 4 test subjects. 3 of these 4 were HCV-RNA positive also. On the other hand, the results of the HCV-PCR were nonuniform in HCV-IgM antibody negative test subjects. The above results demonstrate that in the majority of clinically healthy, anti-HCV positive test subjects with normal transaminase activity, a viremia exists which persists and the course of which may include inflammatory phases. The proof of HCV-IgM antibodies correlates with a viremia. On the other hand, the lack of HCV-IgM antibodies does not exclude viremia.

RESUMEN

The purpose of this study was to evaluate the frequency, nature and significance of the complications of endoscopic sphincterotomy. Between 1989 and 1993 endoscopic sphincterotomy was performed in 973 patients with benign affections of the bileducts. 398 patients were our own and 575 were admitted from other hospitals. The complications were recorded retrospectively on the basis of the discharge reports, which were available for each of our own patients (group A) and for 85% of the admitted patients (group B). Complications in all group A patients mentioned in the discharge reports were recorded and their clinical relevance was evaluated based on the patient records. Complications were mentioned in the reports of 82 (9.2%) of 887 cases and were more frequent in patients of group B (52 of 489: 10.6%) than in patients of group A (30 of 398: 7.6%). Pancreatitis was mentioned significantly more frequent in group B (2.5% vs 5.7%, p < 0.02). Reviewing the patient records of group A showed that clinically significant complications occurred in only 8 (2%) of 398 cases. The other complications mentioned in the discharge reports could not be confirmed or were without clinical significance. Hospitalization was short for these patients (5.3 +/- 2.2 days), which points to the fact that the findings were insignificant. 2 (0.2%) of 887 patients underwent surgery and 2 (0.2%) of 887 patients died due to a complication. These results clearly show that the complication rate determined on the basis of the discharge reports alone overestimates the true morbidity of the procedure. Often, an elevated amylase after ERCP/endoscopic sphincterotomy was erroneously interpreted as a pancreatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Biliary complications are more frequent in laparoscopic than in open cholecystectomy. The aim of the study was to evaluate the diagnostic and therapeutic value of endoscopic retrograde cholangiopancreatography (ERCP) in the management of complications of laparoscopic cholecystectomy. We therefore report on the result of 49 ERCP after laparoscopic cholecystectomy done at our department between January 1991 and March 1993. Patients were referred from 16 different surgical institutions. In 29 cases endoscopic sphincterotomy was performed without complications. Indications for ERCP were "persistent biliary pain" (n = 27), bile leakage (n = 7), pancreatitis (n = 5), abscess (n = 5), painless jaundice (n = 3) and asymptomatic bile duct stone in routine cholangiography (n = 2). In the group of patients with "persistent biliary pain" we found bile duct stones in 12 (80%) of 15 cases with cholestasis and in 3 (30%) of 10 without cholestasis. The stones were endoscopically removed after sphincterotomy. In 2 patients without cholestasis, cannulation of the bile duct failed. 7 patients showed biliary leakage, 4 from inadequate clipping of the cystic stump (2 in combination with a common bile duct stone), 2 from the hepatic duct and 1 from insufficient anastomosis after reconstruction of a common bile duct. After endoscopic sphincterotomy and, if necessary, stone extraction by Dormia basket, leakage from the cystic stump and hepatic duct healed. The insufficient common bile duct anastomosis required reconstruction by hepaticojejunostomy. Three of 5 patients with postoperative pancreatitis had common bile duct stones, while one with chronic pancreatitis had a concrement in the pancreatic duct which was endoscopically removed.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Aluminium-containing phosphate binders were replaced by a calcium and magnesium carbonate-containing antacid in 20 patients on long-term haemodialysis, over a three-month period in all of them, for 12 months in ten. After two months the serum aluminium level fell (mean +/- SD) from 3.0 +/- 1.6 to 1.4 +/- 0.5 mumol/l (P less than 0.001). After three months the serum phosphate level had fallen from 1.8 +/- 0.4 to 1.5 +/- 0.4 mumol/l (P less than 0.05), while during the same period parathormone (PTH-NH2) fell from 1.4 +/- 1.4 to 0.8 +/- 0.7 ng/ml (P less than 0.05). Serum total calcium concentration rose after two months from 2.2 +/- 0.2 to 2.4 +/- 0.2 mmol/l (P less than 0.001). In a third of patients the uraemic acidosis was corrected, standard bicarbonate rising from 18 +/- 2 to 21 +/- 3 mmol/l (P less than 0.05). Serum pH, potassium, sodium, magnesium and alkaline phosphatase did not change significantly. Hypercalcaemia was an expected disadvantage: repeated symptom-free episodes of hypercalcaemia occurred in six of 20 patients during the first three months and in a further two up to 12 months. These episodes were successfully controlled by a reduction of CaCO3/MgCO3 dosage and readministration of Al(OH)3. Extraosseous calcifications were not observed.

RESUMEN

The effects of impaired hepatic function upon the pharmacokinetics of tenoxicam were studied in six patients with cirrhotic liver disease who ingested a single, oral 20 mg dose of the drug. Data from these patients were compared with those obtained from 14 healthy subjects who received the same regimen. Virtually all of the pharmacokinetic parameters computed for the two groups were similar. Cmax in the cirrhotic patients was 2.63 micrograms/ml (s.d. = 0.92) and tmax was 2.5 h (s.d. = 0.8). The corresponding values for the control subjects were 2.77 micrograms/ml (s.d. = 0.72) and 3.2 h (s.d. = 1.6), respectively. The elimination half-life (t1/2) was 53.0 h (s.d. = 19.0) in the cirrhotic patients and 69.2 h (s.d. = 19.3) in the controls. There were no significant (p greater than 0.05) differences between groups with respect to any of these values. Area under curve was significantly (p less than 0.05) smaller in the cirrhotic patients (159 micrograms.h/ml; s.d. = 65) than in the controls (254 micrograms.h/ml; s.d. = 92). The urinary excretion of the 5'-hydroxy metabolite of tenoxicam averaged 21.6% (s.d. = 3.8) of the administered dose in the cirrhotic patients and 22.1% (s.d. = 3.1) in the control subjects. The plasma protein binding of tenoxicam was also very similar in the two groups. The unbound drug fraction averaged 0.8% (s.d. = 0.3) in the cirrhotic patients and 0.8% (s.d. = 0.1) in the 12 control subjects who contributed data to this portion of the study. The single-dose data presented in this report demonstrated substantially unaltered kinetics with no evidence of impaired elimination and drug retention.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

To evaluate the diagnostic and prognostic significance of the N-terminal propeptide of collagen Type III (Col 1-3) in chronic liver disease, the peptide level was measured in the serum of 4 patients with primary biliary cirrhosis, 5 with chronic persistent hepatitis, 12 with chronic active hepatitis, and 1 with autoimmune hepatitis, for a period of 2 to 10 years and compared with liver function and histology. In primary biliary cirrhosis, Col 1-3 peptide levels were always elevated, regardless of medical therapy; however, after liver transplantation in one patient, the Col 1-3 peptide level decreased. In chronic persistent hepatitis, the peptide level fluctuated around the upper limit of normal. Among patients with chronic active hepatitis, the Col 1-3 peptide level normalized in 2 patients during remission, but was elevated in 7 patients who developed cirrhosis. Only in a patient with autoimmune hepatitis was the Col 1-3 peptide level normal, although the patient developed cirrhosis during prednisone therapy. When prednisone was withdrawn, the Col 1-3 peptide level increased. The data suggest that the serum Col 1-3 peptide may estimate the course of liver fibrosis in chronic liver disease and has prognostic value, particularly in chronic active hepatitis. Persistent elevation suggests ongoing fibrosis and development of cirrhosis; normalization suggests remission.
