A novel k-space trajectory measurement technique

OBJECTIVE: To report our experience with erosion of permanent suture or mesh material after abdominal sacrocolpopexy. METHODS: A retrospective chart review was performed to identify patients who underwent sacrocolpopexy by the same surgeon over 8 years. Demographic data, operative notes, hospital records, and office charts were reviewed after sacrocolpopexy. Patients with erosion of either suture or mesh were treated initially with conservative therapy followed by surgical intervention as required. RESULTS: Fifty-seven patients underwent sacrocolpopexy using synthetic mesh during the study period. The mean (range) postoperative follow-up was 19.9 (1.3-50) months. Seven patients (12%) had erosions after abdominal sacrocolpopexy with two suture erosions and five mesh erosions. Patients with suture erosion were asymptomatic compared with patients with mesh erosion, who presented with vaginal bleeding or discharge. The mean (+/-standard deviation) time to erosion was 14.0+/-7.7 (range 4-24) months. Both patients with suture erosion were treated conservatively with estrogen cream. All five patients with mesh erosion required transvaginal removal of the mesh. CONCLUSION: Mesh erosion can follow abdominal sacrocolpopexy over a long time, and usually presents as vaginal bleeding or discharge. Although patients with suture erosion can be managed successfully with conservative treatment, patients with mesh erosion require surgical intervention. Transvaginal removal of the mesh with vaginal advancement appears to be an effective treatment in patients failing conservative management.     

Diagnosis and course of early-onset arthritis: results of a special early arthritis clinic compared to routine patient care

OBJECTIVE: Early arthritis patients referred to an Early Arthritis Clinic (EAC) (n = 233) were compared to 241 patients from the routine out-patient clinic with respect to lag time between the onset of symptoms and the visit to the rheumatologist, clinical presentation and the consistency of the diagnosis after 1 yr. RESULTS: The reduction in median lag time for the EAC patients was at least 3 months. An insidious onset of symptoms was found more often in the rheumatoid arthritis (RA) patients in the routine clinic. In 70% of all cases, a diagnosis could be made after 2 weeks and, if the clinical diagnosis was definite RA, this hardly changed during the following year. Early erosions were seen in 25% of RA patients and were associated with a positive rheumatoid factor (OR 2.08, 95% CI 0.95 4.59). CONCLUSION: An early diagnosis of RA at the EAC is possible and reliable; the high frequency of erosions illustrates the need for early treatment.     

Chlorella virus NY-2A encodes at least 12 DNA endonuclease/methyltransferase genes

OBJECTIVE: To describe outcome and determine predictive factors in juvenile rheumatoid arthritis (JRA) and juvenile spondyloarthopathy (JSpA). METHODS: Seventy-two children with chronic arthritis were studied on first admission to the pediatric rheumatology clinic and after a mean of 9.7 +/- 1.8 yrs of disease duration. RESULTS: At followup, 53 patients had JRA and 19 had JSpA. Eleven (21%) of the patients with JRA did not meet the criteria for JRA on first admission, and 12 (22%) of 54 children diagnosed as having JRA on first admission were later reclassified as having another disease. Remission occurred in 43 (60%) of the 72 patients with JRA and JSpA. Forty-four patients (60%) reported no disability by the childhood or adult Health Assessment Questionnaire and 18 patients (25%) had developed joint erosions. Disease modifying antirheumatic drugs (DMARD) were given to 49 patients (68%) after a median of 0.8 yrs (range 0.2-10.8) disease duration. The patients who developed erosions and disability tended to have started treatment later than those who did not (NS). Active disease 5 years after onset was a predictor of disability in JRA and JSpA (OR 4.5, 95% CI 1.6-12.5). Predictors of joint erosions were long duration of elevated erythrocyte sedimentation rate (ESR) (OR 3.7/yr of elevated ESR, 95% CI 1.9-7.2), long disease duration before first admission (OR 1.5/yr of duration, 95% CI 1.1-2.1), long disease duration before treatment with DMARD (OR 1.8, 95% CI 1.0-3.3), and IgM rheumatoid factor (OR 12 x 10(4), 95% CI 0-1.2 x 10[52]). CONCLUSION: The longterm outcome in JRA and JSpA was more favorable than previously reported. This may be explained by less selection in favor of severely diseased patients and by the use of early aggressive treatment regimes.     

Serum immunoreactive trypsin concentrations in diabetic children

Serum immunoreactive trypsin (SIT) concentrations measured in 616 children with diabetes of recent onset were low, in both boys and girls, in comparison with reference ranges established in patients with non-diabetic, non-infectious illnesses. The mean SIT concentration was 60% of the mean reference level in children tested within three weeks of the onset of diabetes, and about 40% in patients tested six months after the onset of diabetes. Very low SIT levels were found in about 10% of patients, most of whom had no measurable SIT by the assay procedure employed. These very low SIT concentrations were more frequent in older children aged 6-15 years, and in children tested at about 5-6 months after onset. Repeat tests on some of the children showed that the very low SIT levels were generally present for only a limited period.     

The existence of a fatigue syndrome after glandular fever

This prospective cohort study was designed to test whether a distinct fatigue syndrome existed after the onset of glandular fever. Two hundred and fifty primary care patients, with either glandular fever or an ordinary upper respiratory tract infection (URTI) were interviewed three times in the 6 months after the clinical onset of their infection. At each interview a standardized psychiatric interview was given and physical symptoms were assessed. There were 108 subjects with and Epstein-Barr virus (EBV) infection; 83 subjects had glandular fever not caused by EBV and 54 subjects had an ordinary URTI. Five subjects were excluded because they had no evidence of an infection. Principal components analyses of symptoms supported the existence of a fatigue syndrome, particularly in the two glandular fever groups. The addition of symptoms not elicited by the standard interviews gave the full syndrome. This included physical and mental fatigue, excessive sleep, psychomotor retardation, poor concentration, anhedonia, irritability, social withdrawal, emotional lability, and transient sore throat and neck gland swelling with pain. A fatigue syndrome probably exists after glandular fever.     

Orofacial manifestations of Melkersson-Rosenthal syndrome. A study of 42 patients and review of 220 cases from the literature

We investigated orofacial manifestations in 42 patients with Melkersson-Rosenthal syndrome who were examined at our institution between 1965 and 1990. Patient histories and histologic and clinical findings were reviewed in detail. These data were compared with the oral findings in 220 cases that were reported in the literature between 1965 and 1990. There were 28 females in our study. The age at onset of signs and symptoms varied widely with a mean of 33.8 years. Most frequent initial signs were labial edema, facial swelling, and Bell's palsy. During the course of the disease, 75% of all patients had labial swelling, 50% had facial edema, and 33% had Bell's palsy. Swelling, erythema, or painful erosions that affected the gingiva, buccal mucosa, palate, or tongue were common intraoral symptoms. A comparison with patients reported in the literature revealed a similar frequency of extraoral symptoms but more prevalent intraoral symptoms in our patients.     

Detection, significance and treatment of paraprotein in patients presenting with 'idiopathic' proteinuria without myeloma

This paper describes the detection of a paraprotein in blood or urine in 12 of 260 patients with 'idiopathic' proteinuria, most of whom presented with the nephrotic syndrome. None had myeloma at presentation and only two have developed it. Initial clinical and biochemical findings did not suggest paraprotein-associated disease, total serum globulins and individual immunoglobulin levels usually being in the normal range. In seven of the 12 cases the paraprotein was detected only after repeated analysis of serum and urine specimens over months or years. Renal histopathology varied from case to case and is described in detail; amyloid deposition did not occur in patients who excreted kappa chain Bence Jones protein and was extensive in only three. One of these eventually developed myeloma. Patients were aged 27--69 years at onset and were observed without specific therapy for up to 56 months. Glomerular filtration rate tended to decline and proteinuria persisted. All patients have now been treated by a chemotherapeutic regimen consisting of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), cyclophosphamide, melphalan, and prednisolone, in repeated short courses. In some patients, particularly those who had kappa Bence Jones protein, there was striking improvement. Overall survival is good, eight patients being alive 17--90 months after the onset of symptoms. The importance of repeated search for paraprotein in apparently idiopathic renal disease in adults is emphasized.     

Report of two cases presenting with myelodysplastic syndrome during treatment of recurrent breast cancer

Two women with recurrent breast cancer presenting with myelodysplastic syndrome (refractory anemia) during chemotherapy were reported. At diagnosis of myelodysplastic syndrome, white blood cell count, hemoglobin and platelet count were 3,300/mm3, 4600/mm3, 5.5 g/dl, 6.3 g/dl, 1.1 x 10(4)/mm3 and 6.8 x 10(4)/mm3, respectively, in case 1 and 2. Bone marrow taps showed hypercellular marrows with dysplastic changes of erythrocytes, granulocytes and megakaryocytes in both cases. Before the occurrence of the myelodysplastic syndrome, both patients received various cytotoxic agents (mitomycin C: 77 mg, 108 mg; cyclophosphamide: 34,400 mg, 40,000 mg; doxorubicin: 340 mg, 460 mg; methotrexate: 410 mg, 700 mg; and vincristine: 9.5 mg, 14 mg, in case 1 and 2, respectively). One patient died 2 months after the onset of the myelodysplastic syndrome, and the other died 3 months after due to progression of metastatic breast cancer. Risk-benefits analysis of chemotherapy, especially adjuvant chemotherapy, should be performed in cases of breast cancer.     

Identification and characterization of the KlCMD1 gene encoding Kluyveromyces lactis calmodulin

BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is the major cause of morbidity and death after lung transplantation. Therapy has focused on augmented immunosuppression with a variety of agents. Although transient responses are often achieved, sustained remission has been unusual. The outcome of cytolytic therapy for BOS at our center has been analyzed and is reported. METHODS: Between July 1988 and July 1994, 233 patients underwent lung transplantation at Barnes-Jewish Hospital. Among 207 recipients (88.8%) who survived more than 3 months, 81 recipients (39%) had development of BOS; 48 of these patients underwent 64 courses of treatment with a cytolytic agent (antilymphocyte globulin, antithymocyte globulin, or OKT3 monoclonal antibody). The cases of BOS were retrospectively analyzed to determine the impact of cytolytic therapy. RESULTS: The 4-year survival rate was significantly greater in recipients without BOS than in those with BOS (82.8% vs 46.0%; p < .05). Various clinical factors, including diagnosis, forced expiratory volume in 1 second at onset of BOS, presence or absence of pathologically proven bronchiolitis obliterans, type of transplant operation, cytomegalovirus serologic status, and cytomegalovirus pneumonia, were examined, but no significant predictor of survival after the development of BOS was discerned. The mean decrement in forced expiratory volume in 1 second was significantly reduced by cytolytic therapy (-23.5% +/- 2.3% in the 3 months before therapy vs -9.9% +/- 3.5% in the 3 months after the therapy; p < .002). Nevertheless, the stage of BOS progressed over time in spite of therapy in most cases, and only 4 recipients (4.9%) with BOS remained in a lower BOS stage 2 years after treatment. CONCLUSIONS: Recipients with BOS had a significantly lower survival rate than recipients without BOS. No predictor of survival after the onset of BOS was identified. Although cytolytic therapy decreased the rate of decline in pulmonary function in the 3 months after treatment, the stage of BOS ultimately progressed in most patients.     

Therapeutic efficacy of ACTH in symptomatic infantile spasms with hypsarrhythmia

The records of twenty-six infants with both symptomatic infantile spasms and classic hypsarrhythmia were reviewed to determine the efficacy of various ACTH dosages and time of initiation of therapy. Mean age of infantile spasm onset was 6.4 months. Most patients (13) had sustained perinatal hypoxic-ischemic insults. Seventeen patients (65%) had complete cessation of spasms. Between these responders and the 9 nonresponders there was no difference in duration of spasms prior to treatment (2.6 and 2.0 months) or mean ACTH dose (87.4 and 84.5 U/m2, respectively). Infants treated with high-dose ACTH (> 100 U/m2) did not have an improved response rate. The most favorable outcomes were associated with spasm onset at > 8 months of age (all of whom were responders, regardless of dose) or when treatment was started within 1 month of onset of infantile spasms with > 80 U/m2 ACTH (88% responders). Infants treated more than 2 months after onset often did not respond (57%) regardless of dose. Nonresponders with spasm onset at < 4 months of age had the worst prognoses; all had poorly controlled seizures and regressed developmentally. Although all infants in the study were neurologically abnormal, development either improved or did not deteriorate in most responder infants following spasm resolution and one-half remained seizure free. Nonresponder infants continued to have infantile spasms or other seizure types. These data suggest that ACTH is valuable in the treatment of significantly impaired infants with symptomatic infantile spasms, but the most important determinants of outcome may be age of onset and rapidity of treatment rather than dosage.     

Influence of bacterial overgrowth and intestinal inflammation on duration of parenteral nutrition in children with short bowel syndrome

OBJECTIVES: Massive intestinal resection results in short bowel syndrome and necessitates prolonged parenteral feeding. The purpose of this work was to assess the impact of late complications of short bowel syndrome, including intestinal bacterial overgrowth and enterocolitis, on the duration of parenteral nutrition (PN) in comparison with factors evident in the neonatal period. METHODS: Retrospective chart review. RESULTS: Of 49 children, 42 were weaned from parenteral nutrition after a treatment course of 17 +/- 14 months. In these 42, postresection small intestinal length equaled 81 +/- 65 cm; 45% had an ileocecal valve. Small intestinal length in the seven children who were PN dependent was 31 +/- 30 cm (p < 0.05); none had an ileocecal valve (p < 0.05). Bacterial overgrowth occurred in all seven PN-dependent children and in 23 of 42 children eventually weaned from PN (p < 0.05). When bacterial overgrowth was identified before weaning (n = 12), the duration pf PN was 28 +/- 17 months, but when bacterial overgrowth was first identified only after weaning (n = 11), the duration of PN was 16 +/- 13 months (p < 0.05). Small intestinal inflammation correlated with bacterial overgrowth (r = 0.69). Those children with severe enteritis identified before weaning remained on the PN regimen for 36 +/- 15 months, in comparison with 21 +/- 14 months in those with mild enteritis and 13 +/- 11 months in those without inflammation (p < 0.02). CONCLUSIONS: Although the length of small intestine remaining after resection is the best immediate predictor of final success in terminating PN in children with short bowel syndrome, PN is prolonged by bacterial overgrowth and associated enteritis in those who will ultimately be weaned.     

AMO array multifocal versus monofocal intraocular lenses: long-term follow-up

BACKGROUND: Reperfusion therapy by primary coronary angioplasty has been shown to be beneficial for patients who present themselves up to 12 h after the onset of symptoms. However, the relationship between outcome and ischaemic time for patients who present relatively late after the onset of symptoms is still uncertain. The aim of this study was to investigate differences in patient characteristics, left ventricular function and clinical outcome among early (< 3 h), intermediate (3-6 h) and late (6-24 h) treated patients. METHODS AND RESULTS: From August 1990 until December 1995, we studied 496 patients who underwent primary coronary angioplasty for acute myocardial infarction. Patients who underwent reperfusion therapy between 6 and 24 h were more often of female gender and more often had diabetes. Primary coronary angioplasty was less successful with later time to reperfusion. Patients who had reperfusion therapy within 6 h showed recovery of left ventricular function at 6 months follow-up, while the left ventricular function of patients treated late had deteriorated. Reocclusion of the infarct-related vessel at follow-up coronary angiography was highest for patients with an ischaemic time of more than 6 h. They more often suffered a repeat myocardial infarction and had a significantly higher 6 months mortality. After adjustment for age, heart rate at presentation, gender, and the presence of diabetes by multi-variate analysis, ischaemic time remained an independent predictor of both left ventricular function recovery and 6 month mortality. CONCLUSIONS: The time from symptom onset to reperfusion is related to some baseline clinical characteristics, procedural success rate, left ventricular function and clinical outcome.     

Association between catechol O-methyltransferase genotype and violence in schizophrenia and schizoaffective disorder

An 18-month-old dog was examined because of ascites of 1 month's duration. Typical causes of ascites, including hepatic failure, heart failure, and protein-losing enteropathy, were ruled out. The dog's history included being hit by a car 6 months earlier, and the caudal vena cava had an S shape on thoracic radiographs. In addition, the abdominal fluid had a high protein concentration and low cellular content. These findings were all consistent with a diagnosis of postsinusoidal hypertension secondary to obstruction of hepatic venous outflow (Budd-Chiari-like syndrome). During exploratory thoracotomy, the pericardium appeared to have been torn from the heart and was partially wrapped around the caudal vena cava, causing a constriction. The pericardium was removed and the dog recovered without any further complications. Blunt trauma has been previously reported to cause kinking of the caudal vena cava and Budd-Chiari-like syndrome in dogs; but in these dogs, clinical signs of ascites developed a few days to several weeks after the traumatic incident. It appears that, depending on the cause of the hepatic venous outflow obstruction, onset of Budd-Chiari-like syndrome may be delayed for months.     

Bronchiolitis obliterans syndrome: thin-section CT diagnosis of obstructive changes in infants and young children after lung transplantation

PURPOSE: To characterize the thin-section computed tomographic (CT) appearance of bronchiolitis fibrosa obliterans syndrome in infants and young children after lung transplantation. MATERIALS AND METHODS: Thin-section CT studies in six patients with bronchiolitis obliterans syndrome (age range, 2 months to 5 1/2 years) and in 15 control patients without obstructive airway disease (age range, 2 months to 7 years) who underwent bilateral lung transplantation were retrospectively reviewed. The thin-section CT scans were obtained during quiet sleep at a median of 24 months (range, 6-36 months) after transplantation. The CT studies were evaluated for mosaic perfusion, bronchial dilatation, bronchial wall thickening, and mucous plugging Final diagnoses in all patients were based pulmonary function test results. RESULTS: Thin-section CT findings in the six patients with clinically proved bronchiolitis obliterans syndrome were mosaic perfusion in five (83%) bronchial dilation in three (50%), and bronchial wall thickening in one (17%). Of the 15 control patients with normal pulmonary function test results, six (40%) had mosaic perfusion; none had bronchial dilatation or bronchial wall thickening. Mucous plugging was not seen in either group. Only the association of bronchial dilatation with bronchiolitis obliterans syndrome was significant (P = .02). CONCLUSION: Infants and young children with bronchiolitis obliterans syndrome after lung transplantation are more likely to have CT abnormalities than those with normal pulmonary function test results.     

Success of surgery for primary aldosteronism judged by residual autonomous aldosterone production

Since February 1996 we have prospectively assessed residual adrenal autonomy by the fludrocortisone suppression test (FST) in 23 patients 3 months after unilateral adrenalectomy for Conn syndrome and in 45 patients after a longer interval. In regard to blood pressure, 36 (53%) patients were cured of hypertension and the remaining 32 (47%) patients had improved hypertension control at the time of their latest postoperative clinical assessment. In regard to the outcome of surgery, patients who achieved normal suppressibility of aldosterone were regarded as cured, and those who had greater suppressibility after surgery were considered improved. Time since surgery for the whole group averaged 26 months. By these biochemical criteria, 42 patients (62%) were cured by surgery, and the rest improved; 16 (76%) of 21 women were cured, and 26 (55%) of 47 men. The women (mean +/- SD age 47 +/- 11 years) were significantly (p < 0.05) younger than the men (52 +/- 9 years). Preoperative aldosterone levels before and after FST were similar in the cured and improved groups and fell significantly (p < 0.01) in both groups following surgery. After surgical reduction of autonomous aldosterone production, mean plasma renin activity levels increased sixfold in the cured group and threefold in the improved group. Surgical mortality in this group of 68 patients with Conn syndrome was zero.     

Can the liver with Gilbert's syndrome be used as graft of living-related liver transplantation?

Gilbert's syndrome is the common cause of non hemolytic unconjugated hyperbilirubinemia with a prevalance of 3-7%. Gilbert's syndrome may introduce a selection of potential liver donors from brain death patients. We present a case of living-related liver transplantation (LRLT) from a donor with Gilbert's syndrome. A 22-year-old woman had been diagnosed as having liver cirrhosis at the age of 5. She underwent liver transplantation with the donor's left lobe as the graft. The donor, who was the father of the patient, had been diagnosed with Gilbert's syndrome. Although the recipient was well until 11 months after surgery, she died of subacute fulminant hepatitis 16 months after surgery. However, it was clear that the liver with Gilbert's syndrome could be used as a graft of living-related liver transplantation for adult recipients.     

Central nervous system structure and function in Sturge-Weber syndrome: evidence of neurologic and radiologic progression

Sturge-Weber syndrome is characterized by the presence of a port-wine nevus, epilepsy, stroke-like episodes, headache, and developmental delay. We studied 20 cases to test the hypothesis that decreased cerebral blood flow alters neurologic function by affecting cellular glucose metabolism. Group A consisted of 10 patients with a mean age of 1.75 years and early seizure onset (6.8 months), whereas group B was composed of older patients (mean age, 15.3 years) with later onset of seizures (3.7 years). Neurologic disease was more severe in group A, but group B had more widespread structural brain defects - shown on computed tomographic scans and magnetic resonance imaging - and metabolic brain defects shown on hexamethylpropyleneamine oxime and [18F] fluorodeoxyglucose single photon emission computed tomographic scans. Six group A cases had hypoperfusion at baseline and five of nine had worsening of perfusion and glucose metabolism 1 year later. A total of 119 stroke-like episodes occurred in six group A cases and eight group B cases; there were 65% fewer strokes in children treated with aspirin. The data suggest that progressive hypoperfusion and glucose hypometabolism are associated with neurologic deterioration in Sturge-Weber syndrome. Longitudinal studies are needed to better define the natural history of disease and to evaluate the safety and efficacy of aspirin therapy.     

Isaacs syndrome: long-term improvement with intravenous polyvalent immunoglobulins

A 35 year-old man developed a syndrome with muscle cramp, myokimia, generalized, fasciculations, excessive sweating, sleep disorders and severe impairment. It was a syndrome of continuous muscle fiber activity--or Isaacs syndrome--with central disorders (this may be called "Maladie de Morvan"). Previous reports have suggested that Isaac's syndrome might be an autoimmune disorder. Moreover, high doses intravenous immunoglobulins were given resulting in a substantial improvement six months after the onset of this treatment.     

Degradation of commercial detergent products by microbial populations of the Lagos lagoon

We herein report the case of a 53-year-old man with a nonspecific acute colonic ulcer whose liver function deteriorated after he had undergone hepatectomy. He was referred to our hospital for a hepatoma caused by hepatitis B virus and a right hemihepatectomy was performed. His liver function was poor after the operation, and minor complications such as pleural effusion and biliary fistula developed. A large amount of melena was seen 29 days after the hepatectomy and he developed hemorrhagic shock. Superior mesenteric arteriography revealed pooling of blood in both the hepatic flexure of the ascending colon and the cecum. An emergency right hemicolectomy was performed. There was a 5 x 1-mm ulcer 18 cm distal to the ileocecal valve. Numerous erosions were observed to be scattered throughout the colonic mucosa. The patient recovered slowly and was discharged 6 months after the hepatectomy. This is the first report of an acute colonic ulcer that could have been caused by liver dysfunction.
