Are all recurrences of "pure" Sydenham chorea true recurrences of acute rheumatic fever?

We are conducting prospective studies of patients in Santiago, Chile, who have had an attack of rheumatic fever and are receiving continuous secondary prophylaxis with monthly injections of benzathine penicillin G. Throat cultures are obtained just prior to injection each month, and serum antistreptococcal antibody titers (antistreptolysin O and antideoxyribonuclease B) are performed at least every 3 months. During the course of these studies we have observed 17 recurrences of "pure" chorea in 10 patients (six girls). In four recurrences the timing of serologic studies and onset of chorea appeared to exclude the occurrence of an immunologically significant group A streptococcal infection within the preceding 6 to 9 months. In one case the period of serologic follow-up was too brief to allow a definite determination. In the remaining 12 recurrences serologic evidence was suggestive or confirmatory of recent streptococcal infection; however, in several instances the titer elevations were quite modest. Our data suggest that in certain chorea-prone patients, Sydenham chorea may recur after streptococcal infections too weak and transient to be readily detectable or, alternatively, after stimuli other than streptococcal infection.

[Recurrent osteitis and Coxiella burnetii: the relation to chronic recurrent multifocal osteomyelitis].

UNLABELLED: Chronic recurrent multifocal osteomyelitis (CRMO) is a disorder of suspected--but unproved-infectious etiology. OBSERVATION: A girl presented with a typical CRMO involving successively the left fibula, radius, humerus and the right carpus. A Coxiella burnetii infection was indicated during the first attack. Two recurrences occurred in spite of suitable antibiotic treatment and with negative infectious investigation. Two months after stopping antibiotic treatment, a new recurrence associated with antibodies increase and positive bone culture occurred. CONCLUSION: Coxiella burnetii can initiate a CRMO. The mechanism involved is probably a delayed hypersensitivity. CRMO would therefore be the first type of reactive osteitis.

[Diagnosis of recurrence and therapy of recurrence with in situ bone cement filling in the treatment of giant cell tumor].

Bone-cement plugging allows immediate weight bearing and early detection in case of recurrence of giant cell tumor. A recurrence might be treated by either total or partial removal of the old plug and new curettage followed by a second cement plug. The method allows to plan the final surgery for a time which is likely free of risk of recurrence and which appears appropriate in terms of private time scheduling. In addition it saves the valuable autogenous graft.

Recurrence of attic cholesteatoma: different methods of estimating recurrence rates.

One problem in cholesteatoma surgery is recurrence of cholesteatoma, which is reported to vary from 5% to 71%. This great variability can be explained by issues such as the type of cholesteatoma, surgical technique, follow-up rate, length of the postoperative observation period, and statistical method applied. The aim of this study was to illustrate the impact of applying different statistical methods to the same material. Thirty-three children underwent single-stage surgery for attic cholesteatoma during a 15-year period. Thirty patients (94%) attended a re-evaluation. During the observation period of 15 years, recurrence of cholesteatoma occurred in 10 ears. The cumulative total recurrence rate varied from 30% to 67%, depending on the statistical method applied. In conclusion, the choice of statistical method should depend on the number of patients, follow-up rates, length of the postoperative observation period and presence of censored data.

Recurrent nerve/ansa cervicalis nerve anastomosis: a treatment alternative in unilateral recurrent nerve paralysis.

Sectioning of the right recurrent nerve was done in 5 mongrel dogs under general anaesthesia. The distal stump was anastomosed with the ansa cervicalis nerve branch to the sternothyroid muscle. Three to 5 months later the vocal cord movements during light and very light anaesthesia were videorecorded. Under light anaesthesia contraction and medial bulging of the reinnervated right vocal cord occurred in 4 of the dogs. Under very light anaesthesia there was also some adduction of the right vocal cord in these 4 dogs. The right recurrent nerve was then sectioned proximally to the anastomosis and stimulated electrically. In all 5 dogs we observed that electrical stimulation produced a strong adduction of the right vocal cord. Histochemistry of the right vocal and posterior cricoarytenoid muscles showed that reinnervation had taken place. The study indicates that in cases of unilateral vocal cord paralysis an anastomosis between the ansa cervalalis and the recurrent nerve will result in improved phonatory function of the affected vocal cord.

Correlation between MIB-1 staining index and the immunoreactivity of p53 protein in recurrent and non-recurrent meningiomas.

Wild type p53 protein has been shown by recent investigations to be involved in the negative regulation of cell proliferation, whereas aberrant p53 protein has lost this negative regulation of cell growth. Wild type p53 protein, which has a very short half-life, has generally been considered to be undetectable using immunohistochemical methods; however, according to a recent report, wild type p53 protein may accumulate in the nuclei because of a defective ubiquitin pathway. Aberrant p53 protein has a longer half-life, and thus is visible using immunohistochemical methods. In this study, both the proliferative potential represented by the MIB-1 staining index (SI) and the immunoreactivity of p53 protein in 51 intracranial meningiomas were studied applying immunohistochemical staining methods to archival paraffin sections. The correlation among MIB-1 SI, p53 immunoreactivity, histopathologic findings and the clinical course of the meningiomas was also analyzed retrospectively. Although it is not possible with available reagents to distinguish between aberrant p53 protein and wild type p53 protein, statistical analyses show that p53 protein was immunostained both in meningiomas with high MIB-1 SI and in recurrent meningiomas. This demonstrates the close relationship among p53 immunoreactivity, MIB-1 SI, and recurrence; therefore, the presence of p53 protein by immunohistochemical examination may suggest the proliferative activity of meningioma and is capable of serving as a predictor of future recurrence.

Recurrent bronchioloalveolar carcinoma after lung transplantation: radiographic and histologic features of the primary and recurrent tumors.

The chest radiographs of the original and recurrent BAC after lung transplantation in 3 patients were reviewed for correlation with their histologic patterns. The radiographs of non-mucinous BACs in 2 patients were manifested as nodules of variable size, whereas that of mucinous BAC in 1 patient was characterized as hazy opacities. One of the non-mucinous BACs was papillary while the other was lepidic. The original and recurrent tumors were identical radiographically and histologically in the same patients. The study supports the notion that the recurrent BACs found in the donor lungs originated in the recipient.

The role of physical exercise and inactivity in pain recurrence and absenteeism from work after active outpatient rehabilitation for recurrent or chronic low back pain: a follow-up study.

STUDY DESIGN: An observational follow-up. OBJECTIVES: To analyze the role of physical exercise and inactivity on the long-term outcome after active outpatient low back rehabilitation. SUMMARY OF BACKGROUND DATA: There is considerable evidence documenting the efficacy of exercise in the conservative treatment of chronic low back pain, but the role of exercises after the guided treatment period on the long-term success and maintenance of the results is not known. METHODS: One hundred twenty-five patients with low back pain, who had participated in a 12-week active low back rehabilitation program, were asked about subjective pain and disability on the average of 14 months after the treatment. The outcomes were defined as a recurrence of persistent pain and work absenteeism, and a survival or failure analysis was performed between those who had continued exercising and who had been physically inactive. RESULTS: Recurrences of persistent pain during the follow-up period were fewer (P = 0.03) among those who had maintained regular exercise habits after the treatment than among those who had been physically inactive. Similarly, work absenteeism was less (P < 0.01) among physically active than among physically inactive persons. However, patients with good outcome in pain reduction after low back pain rehabilitation were more likely to participate in physical exercise. CONCLUSIONS: Exercises are beneficial after guided treatment in the maintenance of the results of active treatment for recurrent chronic low back pain in the long term, but those with less favorable outcome in rehabilitation are less likely to participate in exercises afterward. In active treatment programs, it is recommended that exercises be incorporated after the guided treatment.

Recurrence and re-recurrence of gall stones after medical dissolution: a longterm follow up.

One hundred patients with radiolucent gall stones less than or equal to 1.5 cm in functioning gall bladders have received oral bile acid dissolution therapy since 1975. Complete data are available on 93 who have received at least six months' treatment. The complete dissolution rate in appropriately selected patients who complied with and tolerated an adequate course of treatment was 55%. By life table analysis the recurrence rates were 13% at one year, 21% at two years, 31% at three years, and 43% at four years. Thereafter the recurrence rate levelled out, being 49% at 11 years. Redissolution was achieved in all seven patients who had a second course of therapy, but was usually followed by re-recurrence. Patients whose gall stones recurred did not differ significantly from those who remained stone free with respect to age, sex, body weight, or time required for dissolution.

Management of recurrent colorectal cancer: another look at carcinoembryonic antigen-detected recurrence.

There is currently controversy regarding the use of serum carcinoembryonic antigen (CEA) in the follow-up of colorectal cancer. This article reviews the most recent clinical data regarding CEA and discusses the rationales for its use in the follow-up of colorectal cancer. The patterns of colorectal cancer recurrence and their variable association with CEA elevation are presented. The contributions of the new imaging modalities, including radiolabeled antibodies, are reviewed and information on the prognosis following resection of recurrences is provided. A practical approach to colorectal cancer recurrences is suggested in two algorithms.

Relationship between plasma LDL concentrations during treatment with pravastatin and recurrent coronary events in the Cholesterol and Recurrent Events trial.

BACKGROUND: Although LDL lowering has been shown to reduce recurrent coronary events in patients with coronary heart disease, little direct information is available on the extent of LDL lowering required to achieve this outcome. METHODS AND RESULTS: The Cholesterol and Recurrent Events (CARE) trial compared pravastatin and placebo in patients who had experienced myocardial infarction (MI) who had average concentrations of total cholesterol <240 mg/dL (baseline mean, 209 mg/dL) and LDL cholesterol (LDL) 115 to 174 mg/dL (mean, 139 mg/dL). Pravastatin reduced coronary death or recurrent MI by 24%. In multivariate analysis, the LDL concentration achieved during follow-up was a significant, although nonlinear, predictor of the coronary event rate (P=.007), whereas the extent of LDL reduction was not significant, whether expressed as an absolute amount (P=.97) or a percentage (P=.76). The coronary event rate declined as LDL decreased during follow-up from 174 to approximately 125 mg/dL, but no further decline was seen in the LDL range from 125 to 71 mg/dL. In multivariate analysis, triglyceride but not HDL concentrations during follow-up were weakly but significantly associated with the coronary event rate. CONCLUSIONS: The LDL concentrations achieved during treatment with pravastatin or placebo were associated with reduction in coronary events down to an LDL concentration of approximately 125 mg/dL. LDL concentrations <125 mg/dL during treatment were not associated with further benefit. Absolute or percentage reduction in LDL had little relationship to coronary events.

Locoregional recurrence (non hepatic abdominal recurrence) of rectal cancer.

Thirty percent of deaths are related to locoreional recurrence. All patients with nonhepatic abdominal recurrence (NHAR) were considered as having locoregional failure. The aims of this study are firstly to retrospectively evaluate the results of potentially curative resection and palliative treatment modalities for a group of 25 patients with NHAR from rectal cancer. The second aim is to determine the effectiveness of R1 resection in these patients in terms of survival. In this study we have followed 25 patients with NHAR of which 10 were able to undergo potentially curative salvage resection, whilst the remaining 15 had either a palliative (R2) or no resection. The goals of treatment for recurrent rectal cancer are palliation of symptoms, a good quality of life, and if possible, cure with a low rate of treatment--related complications. Indications for salvage surgery depend on several factors including the extent of disease, the presence of concomitant illness and the surgeons experience. Systemic disease, systemic disease with peritoneal implants, multiple hepatic metastases, or extensive pelvic involvement preclude surgical treatment for cure. Curative and noncurative surgical procedures were performed width acceptable complications in the series presented hereThe mean survival for the group undergoing R0 resection was 50 months versus 55 months for the group undergoing R1 resection (not significant). Mean survival were 7,3 and 6 months in the groups undergoing R2, NR and NS respectively. The 5-year survival for the 10 patients who had potentially curative resection was 30 per cent versus 0 per cent for 15 patients who had non-curative procedures (p = 0.001). There was 1 post-operative 30 day mortality in the series of 19 patients who underwent surgery. Five patients (6 per cent) developed one or more post-operative complications. Two of them required reoperation.

[Recurrence-free and recurrent urolithiasis: metabolic differences].

Biochemical tests by 12 metabolic blood and urine indices reflecting the condition of renal function and metabolism of urolithogenic substances were made in the course of 1-6 year follow-up of 35 and 79 patients (46 females and 68 males aged 18-65 years) with recurrence-free and recurrent urolithiasis, respectively. The risk of recurrence for uric acid urolithiasis in serum concentration of urea 5.67 +/- 0.14 mmol/l and creatinine 0.090 +/- 0.008 mmol/l, in hyperuricemia and hyperuricuria was associated with elevation of renal excretion of total calcium to 5.88 +/- 0.49 mmol/day and ratio of daily renal excretion of sodium to renal daily excretion of potassium to 3.28 +/- 0.08; for calcium-oxalate lithiasis--with a rise in serum concentration of uric acid to 0.310 +/- 0.042 mmol/l and sodium to 114 +/- 0.8 mmol/l in hypercalciuria and hyperuricuria.

Recurrent appendicitis as a cause of recurrent right iliac fossa pain.

Recurrent appendicitis is defined when patients with recurring similar right iliac fossa pain had acute appendicitis confirmed at the time of operation and the pain completely subsided after surgery. We conducted a retrospective study on our patients with appendicitis. There were 290 patients with appendicitis over a two-year period and 33 patients (11%) had reported recurring pain prior to the presentation. Majority had one prior episode but 15% had multiple episodes of right iliac fossa pain. Fifty-eight percent of the episode occur within six months of the presentation. We conclude that recurrent appendicitis should be considered as a differential diagnosis in patients with recurrent right iliac fossa pain.

[Problems on recurrence after removal of teratoma in pineal region--an experience of recurrence of pineal teratoma 4 years after tumor removal].

A case of teratoma in the pineal region which recurred 4 years after the first tumor removal was reported in this paper. When the patient was 5 years old, she, complained of headache and vomiting, and visited our hospital. As a heterogeneous mass with no enhancement effect was found in the pineal region by CT scan, she was admitted on November 9, 1976. There was no abnormalities on physical examination but neurological examination revealed slight disturbance of conjugate upward gaze (Parinaud's sign). Left vertebral angiogram demonstrated posterior superior displacement of posterior choroidal artery and downward displacement of Rosenthal vein, but early venous filling and tumor stain were not seen. Under preoperative diagnosis of a teratoma in the pineal region, the first operation (left occipital craniotomy and total removal of the tumor) was performed on November 24, 1975. Microscopic examinations revealed that the removed tumor was a mature teratoma in the pineal region. Postoperative course was uneventful and discharged on December 20, 1975. The follow-up study was continued at outside clinic after discharge. There was no signs of recurrence until 3 years after the first operation, but on January, 1981 (4 years after the first operation), she suffered from severe headache and vomiting again and re-admitted to our hospital on February 3, 1981. There was no remarkable neurological deficits except for the mild intracranial hypertensive sign and no changes of findings on angiogram. But CT findings were markedly characteristic. It revealed a heterogenous mass with remarkable enhancement effect in the pineal region and ventricular enlargement. Because a mixed type (teratomatous and germinomatous) of pineal tumors was suspected from the CT findings, irradiation was done after V-P shunt. The tumor was reduced to half size after the first course of 2000 rads irradiation, but there is no more reduction of the size of the tumor following the second course of 2000 rads (total 4000 rads) irradiation. Against the residual tumor, tumor removal was performed on June 2, 1981. Microscopically, the most part of the resected tumor showed fibrous changes caused by irradiation and partially teratomatous compartment. From this result (radiosensitivity and histology) the authors assumed that the recurred tumor could be a mixed type (germinoma and teratoma) of pineal tumor. Postoperative course was uneventful except for a transient disturbance of conjugate upward gaze and she was discharged on June 25, 1981. And now, there is no signs of recurrence 12 months after the second operation. Conclusively, it will be stressed that we should continue follow-up study the case even after total removal of teratoma, especially in the pineal region. Moreover, it was considered that there is a possibility of the changes of the histological features on recurrence of the pineal teratoma. When germinomatous compartment is suspected, irradiation is the first choice and then microsurgical operation should be done against residual tumor.

New strategy of bio-chemoprevention on recurrence of superficial bladder cancer based on a hypothesis of the mechanism of recurrence.

There are theoretical limits to the efficacy of intravesical chemotherapy for prevention of tumor recurrence after transurethral resection of a superficial bladder cancer. Our multi-institutional studies revealed that the direct efficacy of BCG, intravesical instillation for treatment of an existing tumor is very promising. This efficacy persisted over a long period of time, and the subsequent recurrence rate was markedly reduced. Bladder cancer, sometimes earlier known as an occupational disease, might be related to unknown chemical carcinogens. Since enterobacterias are thought to produce carcinogens and mutagens, including nitroso-compounds in the intestinal tract, BLP (lactobacillus casei preparation), treatment may suppress the production of such compounds by altering the intestinal flora. Preclinical studies have demonstrated that BLP suppresses the development of bladder cancer induced by N-butyl-N-(4-hydroxy-butly)-nitrosamine in mice and rats. A double-blind clinical trial recently revealed that BLP was effective for preventing the recurrence of superficial bladder cancer. Bropirimine, a interferon inducer, is now an internationally developing agent for superficial bladder cancer, which is discussed on the basis of Japanese phase II trial data.

A new lymphocyte serotyping using cytotoxic antibodies from secondary recurrent aborters and its application in cases of recurrent abortion and infertility.

Using nonanti-human lymphocyte antigen (HLA) lymphocytotoxic antibodies derived from women with an abnormal pregnancy history including secondary recurrent abortion, a new series of serotyping was performed on lymphocytes from 37 couples (74 individuals), and the compatibility between the couples shown by the typing was investigated. The data demonstrated that both couples with primary recurrent abortion and infertile couples with repeated failure of embryo transfers after in vitro fertilization showed significantly close reaction patterns between partners than normal child-bearing couples by principal component factor analysis. It was concluded that this serotyping provides useful information on histocompatibility in the field of pregnancy immunology and that some cases of infertility because of implantation failure, as well as primary recurrent abortion, might be caused by underlying immunogenetical problems.
