Streptobacillary rat-bite fever: a pediatric problem.

A case of streptobacillary rat-bite fever in an 11-year-old boy from rural North Carolina is described. The child's clinical course was unique in that he developed a subglottic mass and bilateral parotid swelling. He responded initially to tetracycline but relapsed after therapy. Cure was ultimately achieved with a three-week course of penicillin. A review of the literature concerning this unusual clinical entity is presented.

Chloramphenicol in the treatment of typhoid fever.

Six patients with typhoid fever were treated with chloramphenicol. The excellent clinical response in four cases suggests that chloramphenicol is the drug of choice in the treatment of this disease. In one case in which clinical relapse occurred, there was good response to re-treatment. One patient, critically ill, in a typhoid state, and treated late in the course of the disease, died without beneficial effect from chloramphenicol, but the patient had been unable to retain the drug because of vomiting.

Ameobic liver abscess presenting as fever of unknown origin (FUO). Serology, isotope scanning and metronidazole therapy in diagnosis and treatment.

In a study of obscure fevers in Cairo, Egypt, 24 cases of hepatic amoebiasis were diagnosed during a 3-year period from 1977-1980. The counterimmunoelectrophoresis amoebic serologic test was positive in 20 of the 24 patients and was very useful in confirming the diagnosis. The four patients in whom the test was negative had been ill for between 1 and 5 months and had been treated with antibiotics and amoebicidal drugs. Technetium-99 liver scanning localized the site and extent of the abscess and was essential for planning therapy. Treatment with metronidazole and tetracycline resulted in rapid clinical improvement in all except one patient. However, improvement did not indicate cure as our results show: nine patients required needle aspiration of the liver abscess, and seven others had to be referred to surgery for abscess drainage. Large abscesses over 10 cm in diameter should be aspirated to avoid relapse or rupture.

Brucellosis: a retrospective evaluation.

One hundred and sixty-six presumed brucellosis patients were included in the study. These patients were classified as primary (91), relapse (18) and suspected (57) cases according to their clinical presentations, and serologic and microbiologic test results. Primary and relapse cases were evaluated retrospectively according to age, sex, residence, routes of transmission, clinical and laboratory findings, treatment regimens, duration of treatment, and relapse rates. Of the 109 primary and relapse patients, 57 were male and 52 female. The ages of the patients ranged between 16-75 (mean age 40.2). The percentages of the urban and rural residence of the patients were 41.3% and 58.7%, respectively. The most common mode of transmission was consumption of unpasteurized milk and milk products (67.9%). Malaise, fever and sweating were the most frequently observed symptoms (96.3%, 95.4%, 91.7%, respectively). The most common signs were fever (97.2%), splenomegaly (59.6%), and hepatomegaly (37.6%). The liver was the most frequently involved organ (21.1%). Almost all (99.1%) patients were serologically positive. However, the positivity rate of culture was low (15.6%). The most frequently preferred antimicrobial regimen was rifampin and doxycycline combination. The relapse rate was 8.3%. Brucellosis is still prevalent in Turkey as in many other countries in the Mediterranean basin. The clinical presentation of the disease may show regional variations. Patients with a history of occupational or nutritional contact with the bacterium and with a compatible clinical picture should be examined using appropriate diagnostic techniques before any attempt to prescribe an antimicrobial.

Use of recombinant interferon alfa-2b in the treatment of basal cell carcinoma.

BACKGROUND: Several neoplasms including cutaneous T-cell lymphomas, malignant melanoma and Kaposi's sarcoma have been successfully treated with systemic or intralesional interferons (IFNs). Recently, intralesional alpha-IFN has also been employed in the treatment of basal cell carcinoma (BCC). OBJECTIVE: The aim of our study was to evaluate the efficacy of IFN alfa-2b in the treatment of BCC. METHODS: 140 patients with BCC were treated with intra- und perilesional injections of recombinant IFN alfa-2b at a dosage of 1.5-3 x 10(6) IU, three times a week for 4-8 weeks. RESULTS: Complete response was achieved in 94 patients (67.1%), partial response in 33 patients (23.6%) and no response in 13 patients (9.3%). Side effects included fever, headache, fatigue and nausea but were reversible with the use of paracetamol. None of the patients discontinued therapy due to side effects. After a mean follow-up period of 36 months (12-54 months) no relapse has been observed. CONCLUSION: Based on our results, intra- and perilesional IFN alfa-2b represents an effective, alternative treatment for BCC.

Febrile neutrophilic dermatosis associated with acute leukemia.

Febrile neutrophilic dermatosis (Sweet's Syndrome) is an uncommon syndrome characterized clinically by fever, neutrophilia, and erythematous, non-ulcerating papules or plaques on the face, neck, upper thorax, and extremities. A case associated with acute myelogenous leukemia is reported and nine other reported cases associated with acute non-lymphocytic leukemia are reviewed. The appearance and location of the lesions on the face, neck, upper trunk and extremities, a female predominance, an associated fever, marked dermal infiltrates of mature neutrophils, and rapid clearing of lesions with parenteral corticosteroids were manifestations similar to febrile neutrophilic dermatosis not associated with leukemia. Although the etiology of febrile neutrophilic dermatosis associated with acute leukemia is unknown, the resolution of lesions and symptoms with systemic corticosteroids and recurrence with relapse of leukemia suggests an immune process with the leukemic cell population serving as a possible antigenic source.

Idiopathic granulomatous hepatitis with a prolonged course: effect of corticosteroid therapy.

The effect of corticosteroid (or ACTH) therapy on 4 patients with idiopathic granulomatous hepatitis is described. All patients presented with spiking fever and chills and none had jaundice. Only 1 patient had an enlarged tender liver and 3 had splenomegaly. The erythrocyte sedimentation rate was increased in all cases while the white blood cell count was typically normal. Impairment in liver function was insignificant and consisted of a mild elevation of SGOT and alkaline phosphatase activities and prolonged prothrombin time. All patients presented a diagnostic challenge. The diagnosis was established by routine liver biopsies in 3 cases and by laparotomy in the 4th. The etiology could not be established. All patients reacted dramatically to prednisone (or ACTH) after failure of other therapeutic regimens. The disease has, however, been present for 5 years in 1 patient and 10 years in another, Relapses occur after cessation of therapy.

Clinical activity of cisplatin and prolonged oral administration of etoposide in previously treated, anthracycline-resistant, metastatic breast cancer patients: a phase II study.

BACKGROUND: This phase II study evaluates the antitumor activity and tolerance of cisplatin and prolonged oral administration of etoposide in metastatic breast cancer previously exposed to anthracyclines. PROCEDURE: Twenty-seven patients with metastatic breast cancer who developed tumor progression following anthracyclines wer e entered in the study. The patients were treated with combination chemotherapy of cisplatin 50 mg/m(2) IV day 1 and oral etoposide 50 mg/m(2) days 1-17. Cycles were repeated every 29 days. RESULTS: Twenty-six patients were evaluated for toxicity and response. Complete remission was observed in 1 of 26 (4%) patients and partial remission in 12 of 26 (46%). Median duration of response was seven months. Pain relief was noted in 9 of 15 (60%) of the symptomatic patients. Myelosuppression was the major toxicity encountered and four (15%) patients required hospitalization for granulocytopenic fever. Nonhematologic toxicity was mild. CONCLUSIONS: The combination of cisplatin with prolonged oral etoposide is active and tolerable in the management of patients with relapsed metastatic breast cancer previously treated with an anthracycline-based regimen.

Neopterin, beta 2-microglobulin, and acute phase proteins in HIV-1-seropositive and -seronegative Zambian patients with tuberculosis.

Neopterin is a biochemical marker for the activation of the cell-mediated immune system. We measured neopterin, beta 2-microglobulin, and acute phase proteins in 31 HIV-seropositive and -seronegative Zambian patients with tuberculosis, using stored sera that had been obtained at the beginning and at end of antituberculosis treatment. In both HIV-seropositive and -seronegative patients neopterin and acute phase proteins were elevated when tuberculosis was initially diagnosed and fell during treatment. In contrast, the mean beta 2-microglobulin level increased during antituberculous therapy in the HIV-seropositive group. Serum neopterin levels at diagnosis were correlated with other parameters of disease activity (fever, anemia, and weight loss). In both groups, patients with persistently elevated neopterin levels at the end of treatment were more likely to suffer relapse of tuberculosis or other adverse health events in the subsequent follow-up period. Neopterin can be used to monitor the response to antituberculous therapy in both HIV-seropositive and -seronegative patients and may have a prognostic value for the patients' wellbeing in the follow-up period.

Treatment of kala-azar in Brazil with Amphocil (amphotericin B cholesterol dispersion) for 5 days.

We have treated 10 patients suffering from kala-azar in Brazil with Amphocil (amphotericin B cholesterol dispersion) at a dose of 2 mg/kg/d for 5 d, following an earlier study in which this dosage for 7 d was found to cure all of 9 patients, with no relapse during 12 months. In the present study, all patients demonstrated initial resolution of disease. Parasites were absent upon bone marrow re-aspiration 2 weeks after therapy; no spleen extended beyond the costal margin 2 months after therapy; white blood cell counts, platelet counts, and serum levels of albumin rapidly returned to normal. Although one patient relapsed at 5 months, 8 of the other 9 patients had spleens of normal size (undetectable on deep palpation) at 12 months after therapy. Fever, sometimes accompanied by increased respiratory rate, occurred on the first day of drug infusion in 8 of 10 patients and was more severe in patients < 6 years old. Pre-medication with a non-steroidal anti-inflammatory agent (diclofenac potassium) before the next 4 infusions protected against this side effect in 5 of 6 patients. The results of this and our previous study suggest that the most appropriate regimen of Amphocil for kala-azar is 2 mg/kg/d for 7 d, with pre-medication each day, in patients aged > 5 years.

Tuberculosis: still overlooked as a cause of community-acquired pneumonia--how not to miss it.

Tuberculosis (TB) is often mistaken for community-acquired pneumonia (CAP). To avoid missing the diagnosis, we recommend that any CAP patient with upper lobe infiltrate, cavitation, miliary pattern, hemoptysis or >1 month of any of cough, fever, malaise,weakness, night sweats, or significant weight loss, should have sputa submitted for Mycobacterium tuberculosis smear and culture. Any CAP patient failing or relapsing after empiric therapy should be investigated for TB. In the presence of HIV with low CD4 count (< or = 200 cells/mL), the presentation may be atypical, and therefore sputa should be submitted for M tuberculosis. Any HIV patient, regardless of CD4 count, with a known history of positive tuberculin skin test, previous TB, or recent exposure to TB, who presents with CAP, should be investigated for TB.

Role of bone marrow examination in staging Hodgkin's disease: experience in México.

We assessed the value of bone marrow biopsy prospectively in a group of 91 individuals with Hodgkin's disease. The median age of our population was 29 years (range 4-87 years); 59 were males. Most patients (45%) had nodular sclerosing disease and most patients (44%) were in pathological stage II at diagnosis. The bone marrow biopsy showed infiltration by Hodgkin's disease in only three individuals (3.3%); two of these patients displayed constitutional symptoms and had been assigned to stage III before the biopsy. In one case, bone marrow biopsy was the diagnostic procedure, which was performed as part of the investigation of fever of unknown origin. Follow-up periods ranged between 1 and 117 months (median 16 months). All patients achieved complete remission, seven patients relapsed and four were given autologous stem cell transplants. The median survival of the whole group was 117 months, while the 3500-day survival was 76%. As bone marrow biopsy was the diagnostic procedure in one case, bone marrow biopsy was a useful staging procedure in only 2.2% of patients (two out of 90 patients). We suggest that bone marrow biopsy should be only be performed as a staging procedure in a selected subset of patients with Hodgkin's disease (clinical stage III, B symptoms, etc.).

Serologic study on parvovirus b19 infection in childhood acute lymphoblastic leukemia during chemotherapy: clinical and hematologic implications.

PURPOSE: To present a first descriptive serologic study on the clinical and hematologic implications of parvovirus B19 (B19) infection in children with acute lymphoblastic leukemia from the time of initial admission until discontinuation of chemotherapy. PATIENTS AND METHODS: Seventy-five patients were studied by polymerase chain reaction, enzyme-linked immunosorbent assay, sequencing, and immunodiffusion. RESULTS: During the period of observation, 8% (4/48) of B19-seronegative patients seroconverted and infection triggered profound anemia and thrombocytopenia. B19-specific IgG disappeared in 26% (8/31) of B19-seropositive patients, and these patients were significantly younger and the B19 IgG titers were lower on admission compared with patients who continuously displayed B19 IgG. B19 DNA was detected in the seroconverting patients, and this helped in determining the time of infection, which coincided with a B19 epidemic in 75% (3/4) of patients. Patients typically presented with fever and myalgia; a rash, indicative of B19 infection, was observed in only one patient. CONCLUSIONS: B19 infection was able to mimic a leukemic relapse or therapy-induced cytopenia and led to hospital admission, frequent blood sampling, renewed bone marrow aspirates, multiple transfusions of red blood cells or platelets, and cessation of maintenance chemotherapy for up to 3 weeks. The peculiar disappearance of B19-specific IgG, which could not be ascribed to a generalized low level of serum immunoglobulins, has not been previously reported. The results indicate that B19 should be assayed at diagnosis of leukemia to avoid subsequent diagnostic uncertainty, and during treatment in B19-seronegative patients exhibiting unexplained cytopenia.

Epirubicin, methotrexate and bleomycin (EMB) in the treatment of recurrent epidermoid cancer of the head and neck.

During the period May 1989 to November 1990, at the "O. Alberti" Radium Institute of Brescia's General Hospital, 35 patients affected by epidermoid head and neck carcinoma were treated every 28 days with the salvage chemotherapy regimen EMB (epirubicin, 50 mg/m2 i.v. day 1; methotrexate, 40 mg/m2. i.v. days 1, 18; bleomycin, 10 mg/m2 i.v. days 4, 11, 18). Sixteen patients had been previously treated with surgery, 15 with radiotherapy and 4 with chemotherapy. Six patients (Group A) received only 1 cycle of chemotherapy because of disease progression and subsequent death. In another 15 patients (Group B) it was possible to administer 2 cycles of EMB, and 9 of them showed local disease progression and died. Among the remaining 6 patients, evaluated as PR, 1 refused further therapy and 5 were amenable to a previously impossible radiotherapy (4 of them are still alive). Fourteen patients received 3 or more cycles of EMB (Group C): 8 subjects showed progression and died; 1 reached CR and is alive without any evidence of tumor; 5 are in PR (3 of them underwent subsequent radiotherapy and 1 chemotherapy with CDDP). Out of 35 patients, 12 (34%) reached a favorable response (CR or PR) and 8 (22%) are still alive. As regards toxicity, the following adverse events were recorded (< or = 2 Miller's scale): leukopenia (8.5%), thrombocytopenia (5.7%), anemia (14.2%), stomatitis (5.7%), vomiting (5.7%), alopecia (8.5%), and fever (11.4%). It can be concluded that the EMB regimen is very well tolerated and shows good effects in the treatment of patients with relapsed head and neck carcinoma.

[Assessment of endoscopic embolization in the management of esophageal varices].

Between February 1984 and September 1987, endoscopic embolization (EE) was performed in 26 patients with esophageal varices. The effects of EE were evaluated with endoscopic findings according to the general rules for recording endoscopic findings on esophageal varices as specified by the Japanese Research Society for Portal Hypertension. 1) When the result was regarded as effective if a patient had Cw, F1, R-C sign (-), Li and Lm or disappearance of varices, the improvement was found in 66.7% for Color, 79.2% for R-C sign, 54.2% for Form and 45.8% for Location after EE. 2) Recurrence of varices was found in 50% of the patients (12/24) and 4 of 12 cases (33.3%) had rebleeding. 3) When the endoscopic findings before and after EE were compared between relapsed and unrelapsed cases, relapsed patients had more unfavorable endoscopic findings, furthermore, the extent of improvements was also worse than that of unrelapsed cases. 4) As complications, slight fever, dysphagia and epigastric pain were found in most cases, however, all were cured conservatively. In conclusion, EE is useful and safety tool for the improvement of endoscopic findings of the patients with esophageal varices.

A congenital variant of thrombotic thrombocytopenic purpura in two siblings.

We describe two siblings affected by chronic relapsing thrombotic thrombocytopenic purpura from infancy. The elder brother, a 12-year-old boy had 50 such episodes characterized by acute onset of fever, headache, drowsiness, vomiting, dark urine, thrombocytopenia and anemia. The younger sister, a 6-year-old girl, had 8 episodes with the same clinical manifestations. Petechiae and ecchymoses on the extremities were present throughout their lives. Furthermore, anemia with evidence of red blood cell fragmentation and thrombocytopenia were present chronically. Periodical transfusion of frozen fresh plasma prevented recurrent episodes. These cases suggest that there is a congenital variant of thrombotic thrombocytopenic purpura.

Do chest radiographic findings reflect the clinical course of patients with sarcoidosis during corticosteroid withdrawal?

The use of serial chest radiographs to assess disease activity in patients with sarcoidosis is controversial. However, reliance on the symptomatic clinical course to assess disease activity may be misleading. As many patients being treated with corticosteroids have an abrupt clinical deterioration when doses of those medications are decreased, we questioned whether the chest radiograph could depict alterations in disease activity as measured by spirometry in this subset of patients. We retrospectively reviewed the clinical course of all patients with pulmonary sarcoidosis in whom the corticosteroid dose was reduced during a 6-month period. The 15 patients without fever, chills, or purulent sputum during that time were then examined to determine the presence (n = 10) or absence (n = 5) of a symptomatic relapse. All patients who had a symptomatic relapse also had a fall in forced vital capacity of at least 10%, suggesting an increase in disease activity. Serial chest radiographs were evaluated during and after corticosteroid dose reductions and after clinical recovery on higher steroid doses in the patients who had had a relapse. In eight patients, the disease was in radiographic stage 2 (hilar adenopathy and parenchymal lung disease); in seven patients it was in radiographic stage 3 (parenchymal lung disease alone). The disease did not change stage in any patient during the study. Chest radiographs worsened more frequently in patients who had a clinical relapse (seven of 10) than in those who did not have a relapse (zero of five, p less than .05). An alveolar chest radiographic pattern (n = 4) or reticulonodular pattern (n = 3) was noted in the seven patients who had a relapse, with worsening on radiographs often occurring before detection of relapse by symptomatology (four of seven) or spirometry (three of seven). Spirometry and radiographs improved or stabilized after an increase in corticosteroid dose in all 10 patients who had a relapse. We conclude that serial chest radiographs can reflect clinical relapse in patients with sarcoidosis during corticosteroid dose reduction. Furthermore, worsening seen on chest radiographs may be the first evidence of relapse.
