An immunohistochemical evaluation of BMP-2, -4, osteopontin, osteocalcin and PCNA between ossifying fibromas of the jaws and peripheral cemento-ossifying fibromas on the gingiva.
The present study examined histological difference between ossifying fibromas (OF, n=5) and peripheral cemento-ossifying fibromas (PCOF, n=7). Bone morphogenetic proteins (BMP)-2 and -4, osteopontin (OPN), osteocalcin (OCN) and proliferating cell nuclear antigen (PCNA) were used for the immunohistochemical examinations. Oxytalan fibers present at the periodontal tissue were stained to determine the tumor cell origin. Many OFs showed high immunohistochemical reactions for BMP-2, -4 and OPN compared to those of PCOFs. PCNA index (IP) of OFs was significantly higher than that of PCOFs. All the PCOFs showed a high expression of oxytalan fibers. Only two OFs exhibited a small number of oxytalan fibers. These results suggest that PCOF has only little ability to form hard tissue and seems to be a reactive lesion. The expression of oxytalan fibers reveals that OF does not only originate from periodontal tissue.

Lung transplantation for cystic fibrosis.
BACKGROUND: Lung transplantation is a robust therapeutic option to treat patients with cystic fibrosis. PATIENTS AND METHODS: Since 1996, 109 patients with cystic fibrosis were accepted onto our waiting list with 58 bilateral sequential lung transplants performed in 56 patients and two patients retransplanted for obliterative bronchiolitis syndrome. RESULTS: Preoperative mean FEV(1) was 0.64 L/s, mean PaO(2) with supplemental oxygen was 56 mm Hg, and the mean 6-minute walking test was 320 m. Transplantation was performed through a "clam shell incision" in the first 29 patients and via bilateral anterolateral thoracotomies without sternal division in the remaining patients. Cardiopulmonary bypass was required in 14 patients. In 21 patients the donor lungs had to be trimmed by wedge resections with mechanical staplers and bovine pericardium buttressing to fit the recipient chest size. Eleven patients were extubated in the operating room immediately after the procedure. Hospital mortality of 13.8% was related to infection (n = 5), primary graft failure (n = 2), and myocardial infarction (n = 1). Acute rejection episodes occurred 1.6 times per patient/year; lower respiratory tract infections occurred 1.4 times per patient in the first year after transplantation. The mean FEV(1) increased to 82% at 1 year after operation. The 5-year survival rate was 61%. A cyclosporine-based immunosuppressive regimen was initially employed in all patients; 24 were subsequently switched to tacrolimus because of central nervous system toxicity, cyclosporine-related myopathy, or renal failure, obliterative bronchiolitis syndrome, gingival hyperplasia, or hypertrichosis. Ten patients were subsequently switched to sirolimus. Freedom from bronchiolitis obliterans at 5 years was 60%. CONCLUSIONS: Our results confirm that bilateral sequential lung transplantation is a robust therapeutic option for patients with cystic fibrosis.

Primary immunosuppression with tacrolimus in kidney transplantation: three-year follow-up in a single center.
INTRODUCTION: The 1-year results of the phase III US Multicenter Trial comparing tacrolimus- and cyclosporine (Sandimmun)-based immunosuppressive therapy in kidney transplantation revealed a significant reduction in the incidence and severity of acute rejection episodes among patients maintained on tacrolimus. This retrospective, nonrandomized, single-center study represented 3-year data for patient and graft survival and safety in the tacrolimus-treated patients. METHODS: Among 97 consecutive kidney transplant recipients 41 who received tacrolimus and 56 cyclosporine-based immunosuppression were followed for 3 years for patient and graft survivals and for the incidence of acute rejection episodes as well as serious adverse events. RESULTS: The 3-year patient and graft survival rates for tacrolimus and cyclosporine were similar (91.0% vs 90.2%, 96.5% vs 95.0%). However, the incidence of acute rejection episodes was significantly lower in the tacrolimus (17.1%) compared with the cyclosporine group (35.7%, P = .043). There was a higher incidence of headache, posttransplant diabetes, and alopecia reported in the tacrolimus group, whereas hypertension, hypercholesterolemia, and hirsutism were more frequent in the cyclosporine group. The incidences of hand tremor, hyperkalemia, and viral infections were comparable in both groups. Two patients in the tacrolimus group were converted to cyclosporine due to nephrotoxicity and posttransplant diabetes, respectively, whereas 12 patients in the cyclosporine group were converted to tacrolimus as rescue therapy for acute rejection (41.7%), gingival hyperplasia (33.3%), nephrotoxicity (8.3%), neurotoxicity (8.3%), and hirsutism (8.3%), respectively. CONCLUSION: The 3-year results of tacrolimus treatment show excellent efficacy and safety in kidney transplantation. Due to different side-effect profiles, it is necessary to develop individualized immunosuppressive strategies in kidney transplant recipients.

Improved attainment of NKF classified lipid target levels after conversion from cyclosporine to tacrolimus in renal graft recipients.
In an open, prospective, multicenter study, stable renal graft recipients were converted to tacrolimus because of cyclosporine-related side effects. Seventy-five patients were switched primarily because of hyperlipidemia. After the switch to tacrolimus, mean total cholesterol was reduced by 15% at month 6. One hundred seventy-seven additional patients were switched primarily for other indications: hypertrichosis, gingival hyperplasia, and arterial hypertension, and these symptoms also improved after the switch. In this analysis, serum lipid levels were categorized according to a modified standard classification of lipid parameters for renal transplant patients (published by the NKF Work Group). The aim was to estimate the proportion of patients reaching normal lipid levels after the conversion to tacrolimus therapy. In patients with primary indication hyperlipidemia, the proportion with normal cholesterol levels increased significantly from 5.6% at baseline to 37.5% at month 6 (P < .05). For LDL cholesterol, the increase was from 54.1% at baseline to 64.9% at month 6, and for triglycerides the improvement was from 25.4% to 33.8%. HDL cholesterol levels remained stable. Similar changes of lipid parameters were also observed in the subgroups of patients converted to tacrolimus primarily because of other indications. After conversion from cyclosporine to tacrolimus, a significantly higher proportion of stable renal graft recipients reached normal total cholesterol levels. For LDL cholesterol and triglycerides, a trend for normalization was observed. Thus, the improvement of serum lipid levels resulted for many patients in a change to a better level class and improved or normalized their cardiovascular risk parameters.

Effect of calcineurin inhibitors on low-density lipoprotein oxidation.
INTRODUCTION: Low-density lipoprotein (LDL) oxidation is considered a key factor in the biological processes that trigger and accelerate atherosclerosis. Reported data suggest that tacrolimus improves the lipid profile in renal transplant recipients. OBJECTIVE: The objective of this study was to analyze the effect of converting from cyclosporine to tacrolimus on lipoprotein oxidation in renal transplant recipients. METHODS: We studied a group of 12 recipients (6 men and 6 women of mean age 55 +/- 11 years) treated with a cyclosporine-mycophenolate mofetil (MMF)-prednisone combination that was converted to tacrolimus-MMF-prednisone because of gingival hyperplasia. The LDL fraction was isolated by density-gradient ultracentrifugation. Oxidative stress was studied before converting (baseline) and at 6 and 12 weeks, thereafter by in vivo oxidation analysis of LDL, a direct assay of oxidized LDL (oxLDL) and oxLDL autoantibodies (Ab-oxLDL) using enzyme-immunoassay techniques. We measured total cholesterol (TC), triglyceride, LDL-cholesterol, high-density lipoprotein (HDL)-cholesterol, ApoA1, ApoB, and Lp(a) levels. RESULTS: The change to tacrolimus resulted in significant decreases in TC levels, 213 +/- 30 (B) versus 185 +/- 27 (12s) (P < .01); LDL, 129 +/- 24 (B) versus 104 +/- 14 (12s) (P = .002); and ApoB 98 +/- 15 (B) versus 85 +/- 10 (12s) (P < .01). HDL levels significantly increased (45 +/- 10 vs 48 +/- 10 [12s]; P = .018), whereas oxLDL concentrations decreased significantly after conversion (B) (55.42 +/- 10.61 vs 12s 45.76 +/- 10.21; P < .01). Converting to tacrolimus produced a nonsignificant decrease in Ab-oxLDL (baseline 204.88 +/- 134.49 vs 12s 179.51 +/- 143.54). A correlation was observed between LDL and oxLDL (r = 65, P = .02 [B] and r = 0.7, P = .01 [12s]) but not between oxLDL levels and Ab-oxLDL concentration (r = -0.05, P = .87 [3] and r = -0.1, P = .77 [12s]). CONCLUSIONS: In renal transplantation, tacrolimus therapy was associated with a better lipid profile and lower in vivo LDL oxidation when compared with cyclosporine treatment.

Effective treatment of ligneous conjunctivitis with topical plasminogen.
PURPOSE: The etiology of ligneous conjunctivitis is now known to be due to an underlying type 1 plasminogen deficiency. We hereby report the clinical features of three cases and their response to topically administered plasminogen. DESIGN: Observational case series. METHODS: Two Caucasian females aged 5 years and an 18-month male of north African descent presented with a membranous conjunctivitis, which recurred after surgical excision. Case 1 presented before the association with plasminogen deficiency was known with a bilateral chronic membranous mucopurulent conjunctivitis from the age of 14 months associated with bronchiolitis and gingival hyperplasia. A diagnosis of ligneous conjunctivitis was entertained and a number of drops were instituted. At the age of 4 years plasminogen levels were ordered. Case 2 presented at the age of 4 years with a unilateral chronic membranous conjunctivitis. Plasminogen levels were requested as soon as a diagnosis of ligneous conjunctivitis was suspected. Case 3 was born with congenital hydrocephalus. Conjunctivitis was treated with antibiotics from the age of 1 month. He presented to the eye clinic at the age of 5 months when a clinical diagnosis of ligneous conjunctivitis was entertained and treated with a number of medications. Plasminogen levels were available at 9 months of age. RESULTS: The two female patients returned plasminogen levels of 0.25 U/ml and 0.3 U/ml, well below the normal level of 0.7-1.0 U/ml. Functional plasminogen levels in the male infant were not recordable with plasminogen antigen levels of 0.125 U/ml (normal range, 0.52-1.82). All cases have responded well to excision of the membranes and institution of topical plasminogen drops. There has been no recurrence with more than 12 months' follow-up. CONCLUSIONS: With the knowledge of the etiology of ligneous conjunctivitis, efforts are underway to identify the best method of delivery of plasminogen. Topical plasminogen concentrate from fresh frozen plasma holds promise as the definitive treatment for this chronic membranous conjunctivitis

Periodontal complication during orthodontic therapy. A case report.
Occasionally periodontal complications arise during adult orthodontic therapy, although conditions may also occur in adolescent patients. This case report describes the periodontal condition that developed during orthodontic treatment of an adolescent girl. Eleven months after the start of treatment, an unusual hyperplastic soft-tissue lesion developed that did not respond to conservative treatment. The case history, orthodontic treatment, periodontal treatment, histopathology, and follow-up are described. Suggestions for prevention and early diagnosis of similar problems are reviewed since particular periodontal infections may progress subclinically.

Bicêtre hospital experience with sirolimus-based therapy in human renal transplantation: the Sirolimus European Renal Transplant Study.
In 11 European centers, first cadaveric renal allograft recipients were randomized to CsA (n = 42) or sirolimus (n = 41). Dosing of these agents was concentration-controlled and open-labeled. All patients received corticosteroids and azathioprine. At 12 months, graft survival (98% sirolimus vs 93% CsA), patient survival (100% vs 98%), and incidence of biopsy-confirmed acute rejection (41% vs 38%) were similar. Serum creatinine was lower with sirolimus, significantly (P </=.05) so at 3 and 4 months, and serum uric acid and magnesium were normal. Laboratory abnormalities were reported significantly more often with sirolimus, which included hypertriglyceridemia (51% vs 12%), hypercholesterolemia (44% vs 14%), thrombocytopenia (37% vs 0%), leukopenia (39% vs 14%), and, of lesser importance, increased liver enzymes and hypokalemia. These abnormalities improved 2 months after transplantation when the sirolimus target trough level was lowered from 30 to 15 ng/mL. Occurrence of cytomegalovirus was comparable (14% vs 12%), but incidence of herpes simplex (24% vs 10%, P =.08) and pneumonia (17% vs 2%, P =.03) were higher with sirolimus. No gingival hyperplasia was seen with sirolimus, tremor was rare, and hypertension was less frequent (17% vs 33%). Two malignancies were observed with CsA, none with sirolimus. Results at 12 months suggest that sirolimus can be used as base therapy in the prophylaxis of acute renal transplant rejection, and has a safety profile that differs from that of CsA.

Tacrolimus in heart transplantation.
Tacrolimus (Tac), which blocks T- and B-cell proliferation by inhibiting calcineurin, was first used for immunosuppression following heart transplant (HT) in 1989. Two multicenter randomized trials have compared Tac to the oil-based cyclosporine (CsA) formulation (both combined with azathioprine and steroids) in HT patients. The two drugs displayed similar patient survival rates and incidences of rejection, nephrotoxicity, diabetes, and infections. The Tac group however, showed a lower incidence of arterial hypertension (and, in one study, of dyslipidemia). A pilot study of Tac in combination with mycophenolate mofetil (MMF) and steroids suggested that maintenance of serum mycophenolic acid levels at 2.5 to 4.5 microg/mL yields lower rejection rates without greater toxicity than previous regimens. Currently, a European multicenter randomized trial is comparing Tac with Neoral CsA, both used in combination with MMF, steroids, and induction antibodies. For patients undergoing primary immunosuppression with CsA, Tac has proved effective for rescue from steroid-resistant acute rejection. It also has tentatively been used without other drugs in selected patients. It is a valid alternative to CsA in current immunosuppressive regimens, because it does not cause gingival hyperplasia or hirsutism and, thus, may improve the quality of life and treatment compliance of female and pediatric patients. It may be preferable to CsA for patients with arterial hypertension or intractable dyslipidemia. Current and future studies will clarify the efficacy and safety of regimens combining Tac with MMF or rapamycin.

Epilepsy control with phenobarbital or phenytoin in rural south India: the Yelandur study.
BACKGROUND: Epilepsy is a controllable disorder if detected and treated early. For most families in rural areas of less developed countries, however, treatment can be delayed because of the inaccessibility of specialist neurological assessment facilities. We aimed to find a practical solution to rural epilepsy control by doing a non-randomised trial in south India. METHODS: 135 patients with partial or generalised tonic-clonic seizures agreed to long-term treatment with phenobarbital (n=68), phenytoin (n=60), or both (n=7). Drugs were given once daily, and at the lowest effective dose, by trained primary-care physicians and health workers. All management was entirely clinical. The main outcome measure was absence of seizures of any type for at least 2 years (terminal remission). Analysis was by intention to treat. FINDINGS: The proportion with terminal remission at each of 4 successive years of follow-up ranged from 58% to 66% for patients who were drug compliant and who had a lifetime total of 30 or fewer generalised tonic-clonic seizures. The corresponding range for patients who were not compliant and who had ever had more than 30 such seizures was 6-16%. Multivariate logistic regression analysis confirmed that strict drug compliance and early treatment were important predictors of a 2-year terminal remission. Clinical adverse effects were noted in three (4%) patients on phenobarbital and 67 (43%) of those on phenytoin (mainly in the form of gingival hyperplasia). INTERPRETATION: In rural areas of less developed countries, epilepsy control in its early stages can be practical and effective with existing resources. The key to success is a combination of trained primary-care physicians, health workers, inexpensive phenobarbital, drug compliance, health education, and follow-up.

Cyclosporine therapy for severe sight-threatening uveitis in children and adolescents.
OBJECTIVE: To review the safety and efficacy of cyclosporine in the treatment of children with severe bilateral sight-threatening intermediate uveitis or panuveitis. DESIGN/PARTICIPANTS: A retrospective chart review was performed on all children younger than 18 years of age with chronic bilateral sight-threatening uveitis who were treated with cyclosporine. MAIN OUTCOME MEASURES: Assessment of the therapeutic efficacy and development of adverse effects of cyclosporine after 6 months, 2 years, and 4 years of therapy was performed. RESULTS: Between 1983 and 1992, 15 children and adolescents were treated with cyclosporine. After 6 months, visual acuity improved or stabilized in 82.1% of eyes, while median vitreous inflammation decreased from 2.0 to 0.5. After 2 and 4 years, visual acuity improved or stabilized in 64% and 75% of eyes, respectively. Median vitreous inflammation remained 0.5 after 2 and 4 years of therapy. Mean creatinine clearance and hemoglobin values decreased and serum creatinine increased after 6 months. After 2 years, only mean hemoglobin values remained decreased. After 4 years, no significant differences were noted in any of the laboratory studies. The most frequently noted side effects included transient increases in serum creatinine in 53%, gingival hyperplasia in 40%, and hirsutism in 20% of patients. CONCLUSIONS: The authors' results suggest that cyclosporine is a safe and effective therapy for the treatment of children with severe bilateral sight-threatening intermediate uveitis or panuveitis.

Characterization of collagens in phenytoin-enlarged human gingiva.
The collagen content and composition of human gingivae enlarged due to phenytoin medication were compared to normal and inflamed gingival tissues. Phenytoin-enlarged gingiva contained significantly higher amounts of collagen. The ratio of type I to type III collagen was different in enlarged tissue, with less type I and an elevated amount of type III collagen present. The amount of type V collagen did not differ among normal, inflamed and phenytoin-enlarged gingivae.
