Prednisone in MOPP chemotherapy for Hodgkin's disease.
(1/1129)
High remission rates have been produced by MOPP (mustine, vincristine, procarbazine, and prednisone) chemotherapy in patients with advanced Hodgkin's disease, but the prednisone component has caused adverse effects in patients who have undergone radiotherapy. The remission rates and length of remission were reviewed in 211 patients with Hodgkin's disease who received chemotherapy either with or without prednisone. In contrast to the findings of a British study, there were no significant differences in remission rates or length of remission between patients who had received prednisone and patients who had not. There were differences between the British prospective study and this retrospective one, but it is difficult to know what accounted for the substantial differences in the findings. (+info)
Ki-1 (CD30)-positive anaplastic large cell lymphoma, sarcomatoid variant accompanied by spontaneously regressing lymphadenopathy.
(2/1129)
Although it has been reported that primary Ki-1 (CD30)-positive anaplastic large cell lymphoma (ALCL) of the skin may undergo spontaneous regression, it is rare for ALCL without cutaneous involvement to have spontaneously regressing lymphadenopathy. We report a case of sarcomatoid variant of ALCL accompanied by spontaneously regressing lymphadenopathy. The patient had gastric and pulmonary involvement of ALCL in addition to systemic lymphadenopathy, but with no cutaneous involvement. The lymphadenopathy spontaneously improved gradually during a period of one month without any treatment. At the same time, multiple small nodules in both lung fields decreased on chest computed tomography and multiple elevated gastric tumors with dimples were endoscopically recognized to have improved. He has since been treated with combination chemotherapy because of recurrence of the lymphadenopathy. (+info)
B cell lymphoproliferative disorders following hematopoietic stem cell transplantation: risk factors, treatment and outcome.
(3/1129)
Twenty-six cases of B cell lymphoproliferative disorder (BLPD) were identified among 2395 patients following hematopoietic stem cell transplants (HSCT) for which an overall incidence of BLPD was 1.2%. The true incidence was probably higher, since 9/26 of the diagnoses were made at autopsy. No BLPD was observed following autologous HSCT, so risk factor analyses were confined to the 1542 allogeneic HSCT. Factors assessed were HLA-mismatching (> or = 1 antigen), T cell depletion (TCD), presence of acute GvHD (grades II-IV), donor type (related vs unrelated), age of recipient and donor, and underlying disease. Factors found to be statistically significant included patients transplanted for immune deficiency and CML, donor age > or = 18 years, TCD, and HLA-mismatching, with recipients of combined TCD and HLA-mismatched grafts having the highest incidence. Factors found to be statistically significant in a multiple regression analysis were TCD, donor age and immune deficiency, although 7/8 of the patients with immunodeficiencies and BLPD received a TCD graft from a haploidentical parent. The overall mortality was 92% (24/26). One patient had a spontaneous remission, but subsequently died >1 year later of chronic GVHD. Thirteen patients received therapy for BLPD. Three patients received lymphocyte infusions without response. The only patients with responses and longterm survival received alpha interferon (alphaIFN). Of seven patients treated with alphaIFN there were four responses (one partial and three complete). These data demonstrate that alphaIFN can be an effective agent against BLPD following HSCT, if a timely diagnosis is made. (+info)
The value of thymectomy in myasthenia gravis: a computer-assisted matched study.
(4/1129)
In the absence of a prospective randomized study of patients treated conservatively or with thymectomy, a computer-assisted retrospective matches study was devised. Of 563 patients treated for myasthenia gravis without thymoma up to 1965, 104 had thymectomy. With computer assistance, each surgical patient was matched with a medical patient on the basis of age, sex, and severity and duration of disease. On this basis 80 of the 104 surgical patients could be matched satisfactorily. There were 16 males and 64 females in each of the matched surgically treated and medical control groups. A complete remission was experienced by 27 of the 78 patients in the surgical group as compared to 6 of the medical group. Improvement was noted by 26 of 78 surgically treated patients and 13 of 78 receiving medical treatment. Survival for patients having thymectomy. Thirty-four patients in the medical group had died as compared to 11 in the surgical group. Comparison of survival in relation to sex, duration of symptoms, or age (less than 30 or less than 30 years) did not show a significant difference. Until more effective treatment is available for myasthenia gravis, thymectomy deserves consideration for both sexes, and with increased age or long duration of symptoms. (+info)
Unidirectional dyslexia in a polyglot.
(5/1129)
Alexia is usually seen after ischaemic insults to the dominant parietal lobe. A patient is described with a particular alexia to reading Hebrew (right to left), whereas no alexia was noted when reading in English. This deficit evolved after a hypertensive right occipitoparietal intracerebral haemorrhage, and resolved gradually over the ensuing year as the haematoma was resorbed. The deficit suggests the existence of a separate, language associated, neuronal network within the right hemisphere important to different language reading modes. (+info)
Case report. Post-traumatic tibial recurvatum: resolution with growth.
(6/1129)
The outcome of proximal tibial fractures in children is often complicated by the development of malalignment. Progressive valgus deformity is frequently seen, but is known to correct spontaneously in a high proportion of cases; however, recurvatum of the tibia usually requires surgical intervention. We present a child with a proximal tibial metaphyseal fracture who developed increasing tibial recurvatum which corrected spontaneously. (+info)
99mTc-bicisate and 99mTc-HMPAO SPECT imaging in early spontaneous reperfusion of cerebral embolism.
(7/1129)
Two patients with a cerebral embolism were evaluated by using both 99mTc-ethyl cysteinate dimer (ECD, or Bicisate) and 99mTc-hexamethylpropyleneamine oxime (HMPAO) single-photon emission computed tomography (SPECT). In one patient, 99mTc-ECD SPECT images revealed hypoactivity in a reflow hyperemic area where an infarct was seen later on CT scans. In another patient, a reperfused area showed hyperactivity on 99mTc-ECD SPECT without any abnormality on follow-up CT. 99mTc-ECD represents a potential agent with which to evaluate cerebral tissue viability in early reperfusion after ischemia.

Cerebral gumma showing spontaneous regression on magnetic resonance imaging study--case report.
(8/1129)
A 75-year-old male presented with the complaint of headache. Magnetic resonance (MR) imaging demonstrated a low-signal intensity area on both T1- and T2-weighted images with ring-like enhancement and adhesion of the dura appearing as dural tail sign. Follow-up MR imaging demonstrated spontaneous regression, so the preoperative diagnosis was malignant lymphoma. Histological examination revealed typical granuloma. Treponema pallidum hemagglutination assay tests of serum and cerebrospinal fluid were positive for active syphilis. The enhanced mass totally disappeared after 4 months of erythromycin therapy. The final diagnosis was cerebral gumma. The incidence of syphilis is increasing, so cerebral gumma should be included in the differential diagnosis of hypovascular tumors that involve both the parenchyma and dura even in the presence of spontaneous regression.
