The efficacy and safety of a combination regimen using cefmetazole (CMZ) and netilmicin (NTL) were evaluated in the treatment of infections complicated with hematological disorders. Primary diseases in 31 patients included in the evaluation were acute myelocytic leukemia (3 cases), acute lymphocytic leukemia (2 cases), malignant lymphoma (14 cases), chronic myelocytic leukemia (2 cases), chronic myelocytic leukemia blast crisis (4 cases), myelodysplastic syndrome (2 cases), aplastic anemia (3 cases), and malignant histiocytosis (1 case). Complicated infections included 29 cases of suspected septicemia, 1 case of septicemia and 1 case of pneumonia. Clinical responses were excellent in 6 (19.4%), good in 12 (38.7%), fair in 1 (3.2%) and poor in 12 (38.7%). The total clinical efficacy rate was 58.1%. No significant effect of initial neutrophil counts was observed on response rates. Patients who showed increasing neutrophil counts during therapy had higher response rates than those in whom the neutrophil count decreased or remained unchanged at levels less than 500/mm3 in after neutrophil counts. No side effects were observed in any of the 31 patients. In conclusion, this combination therapy of CMZ and NTL thus appears to be useful and safe in therapies for infections complicated with hematological disorders.

Intensive chemoradiotherapy, with or without additional local radiotherapy, and unpurged autologous marrow transplantation was given to 68 patients with progressive non-Hodgkin's lymphoma. Responses were attained in 44 patients (65%, 95% confidence intervals [CI], 52% to 76%), including 37 who achieved complete responses. Fifteen patients (22%, 95% C.I. 13% to 34%) remain free of disease (including 11 continuously) at a median of 5.3 (range 3.1 to 9.1) years later. Higher Karnofsky scores (P less than .01, Mann-Whitney U test) and the absence of a history of prior radiotherapy (P = .02, chi 2 test) were associated with achievement of complete plus partial responses. Higher Karnofsky scores (P less than .01, Mann-Whitney U test) and less resistant disease status at transplantation (P = .04, chi 2 test) were significant when calculations were limited to complete responses. Karnofsky scores were also associated with the probability of freedom from progression (P = .02, log-rank) for responding patients. Also, Karnofsky scores and the absence of prior radiotherapy (P less than .01 and P = .01, respectively, log-rank) were associated with improved survival. Progressive lymphoma was the chief cause of failure; progression usually occurred less than 6 months after transplantation, most often at the sites of active disease before the transplant. However, five patients (including four with high-grade non-Hodgkin's lymphoma) suffered hematogenous patterns of relapse; four of these five patients had no prior history of marrow involvement. Other causes of mortality included interstitial pneumonitis, sepsis, hemorrhage and renal failure. Intensive chemoradiotherapy and autologous marrow transplantation produces durable remissions in some patients with progressive non-Hodgkin's lymphoma. Since such therapy is more effective when given to patients with signs of less advanced disease, earlier treatment would be the simplest way to produce improved results. However, improved conditioning regimens will also be needed, and measures to reduce occult lymphoma stem cell contamination with the autograft may also be required to increase the likelihood of cure in some patients.

Nosocomial septicemias that occurred over a 32-month period on an inpatient medical oncology service were reviewed. One hundred four episodes of septicemia occurred in 84 patients, 33% with solid tumors and 67% with leukemia or lymphoma. Sixty were primary septicemias, with the remainder being secondary. Of the 118 isolates recovered, 42% were Gram-positive organisms, 45% Gram-negative organisms, and 13% were fungi. Coagulase-negative staphylococci and Escherichia coli were the most common Gram-positive and Gram-negative isolates, respectively. The effect of the type of malignancy, neutropenic status, and presence of a central venous access device (CVAD) on the isolate(s) recovered was studied. Coagulase-negative staphylococci were more commonly isolated from leukemia-lymphoma patients (26% vs. 3%, P less than .01), while Gram-negative isolates (63% vs. 36%, P = .01), specifically Klebsiella species (21% vs. 5%, P = .02), were more common in solid tumor patients. Staphylococcus aureus was isolated more frequently from non-neutropenic patients than from those with neutropenia (19% vs. 4%, P = .02). Gram-positive isolates were more commonly found in patients with a CVAD (51% vs. 29%, P = .03), in particular coagulase-negative staphylococci (29% vs. 2%, P less than .001). In contrast, Gram-negative isolates (62% vs. 34%, especially Klebsiella species (22% vs. 3%, P less than .01) and S. aureus (18% vs. 5%, P = .07) were more commonly isolated from patients with no CVAD. Neither neutropenia nor the presence of a CVAD predisposed to early mortality. Our data suggest that empiric antimicrobial coverage for presumed nosocomial septicemia in the febrile cancer patient should include vancomycin for patients with a CVAD to cover coagulase-negative staphylococci and a cephalosporin for patients with solid tumors, especially those without a CVAD, to cover Klebsiella species.

A 20-year-old man developed a massive nephrotic syndrome, rapidly complicated by pulmonary embolism and septicemia. Two renal biopsies taken 3 months apart showed minimal change glomerulonephritis. Treatment with prednisolone 1.5 mg/kg/day failed to induce a sustained remission, then monotherapy with cyclosporin A (CsA, 5 mg/kg/day) was started. Complete remission was obtained after 15 weeks. CsA was gradually tapered to 3 mg/kg/day. Twenty-two months after starting CsA, a routine examination disclosed a right sub-clavicular lymph node, of which histological examination showed a class 4 large cell Hodgkin's lymphoma. CsA was abruptly withdrawn and a polychemotherapy resulted in lymphoma remission after four courses. Ten months later, Hodgkin's disease is currently in remission and there is no relapse of proteinuria.

Fifteen dogs with relapsed lymphoma were treated with doxorubicin and dacarbazine (ADIC) to reinduce remission. All the dogs' lymphomas had become resistant to prior therapy with doxorubicin alone. Five of the 15 dogs had a complete response to the first treatment with ADIC, and three had partial responses. Of the eight dogs receiving a second cycle, two had complete responses, and one had a partial response. One dog that received a third ADIC treatment no longer responded. The median survival time from the first ADIC treatment for all dogs was 45 days (range, 18-241 days). The five dogs having complete responses to the first ADIC treatment had a median survival time of 105 days (range, 45-241 days) after this treatment. Toxicity due to ADIC treatment was acceptable and did not exceed that seen when doxorubicin was given as a single agent. The treatment resulted in severe neutropenia in three dogs. One dog died due to neutropenic sepsis. Vomiting, diarrhea, and anorexia occurred, but were tolerable, resulting in hospitalization in only one instance. ADIC is apparently a useful chemotherapeutic combination to reinduce remission in some dogs with relapsed lymphoma.

This review describes the transmission, clinical picture and immunological abnormalities of HIV infection in children in general, and the special problems of AIDS in African children. The review begins with a thorough introduction to the epidemiology of AIDS. Transmission to children generally involves vertical transmission by placental transfer or transmission of HIV via transfusion of blood and blood products, or by contaminated needles. Casual transfer is unknown, and only a few cases of transmission via breast milk are known. The clinical picture of HIV infection in infants and children differs from that in adults in 3 important aspects: earlier onset, different clinical presentation and existence of AIDS embryopathy. The average onset was 5 months of age. The most common symptoms in young children are chronic interstitial pneumonitis without demonstrable etiology, hepatomegaly, failure to thrive, adenopathy, diarrhea, oral or perineal thrush, eczema and thrombocytopenia. The common opportunistic infections are pneumocystis carinii pneumonia, cytomegalovirus, Epstein-Barr virus, Cryptosporidium diarrhea, pyogenic infections of the middle ear and gram-negative septicemia. Several infections seen in adult AIDS cases are rare in children: mycobacterium avium-intracellulare, toxoplasma gondii, hepatitis B, as well as Kaposi's sarcoma, malignant lymphoma and cardiac abnormalities. The AIDS embryopathy or HIV dysmorphic syndrome is characterized by immunological abnormalities, growth failure, and craniofacial dysmorphism, particularly microcephaly, prominent box-like forehead, hypertelorism, flattened nasal bridge, obliquity of the eyes, blue sclerae and patulous lips. AIDS in African children is extremely difficult to diagnose because of similarities between the presenting symptoms and those commonly seen in sick children there, many of whom are also immune compromised. Where serotesting is available, the picture is complicated by cross reaction between the test agents and some factor found in sera from malaria patients. Seropositivity in some areas is high, increased by the prevalence of transfusion and injection treatments. Diagnosis is made more difficult by lack of laboratory facilities and difficulties in follow-up for pediatric patients. The CDC definitions of AIDS and ARC, and the WHO/CDC definitions of AIDS are appended.

To focus attention on the problem of infant mortality in Lebanon, data were compiled on infant mortality from 1978 to 1986 at the American University of Beirut Medical Center. Causes of death are analyzed for 602 males and 398 females. 54.9% deaths occurred at 1 month of age and 77.4% died within the 1st year. Autopsies were performed on .7%. 37.7% of all neonatal deaths were due to neonatal diseases such as hyaline membrane disease, asphyxia neonatorum, immaturity, necrotizing enterocolitis, hemorrhage, hemolysis, meconium aspiration, and kernicterus. Better prenatal care would reduce this group, or the administration of corticosteroids to the mother 24-48 hours prior to delivery, as well as rapid resuscitation at birth and prevention of the 5 curses: hypoxemia, hypoglycemia, hypothermia, hypotension, and acidosis. Although unavailable in Lebanon, administration of surfactants through an endotracheal tube would also help. Infections constitute 25.1% of deaths; many are preventable through adequate public health measures and strict personal hygiene, i.e., diseases such as sepsis, pneumonia, meningitis, gastroenteritis, hepatitis, encephalitis, and 1-2 cases of the following: diphtheria, measles, peritonitis, tetanus, tuberculosis, cytomegalis inclusion, herpes, parathyphoid, pertussis, poliomyelitis, and shigellosis. Congenital diseases were 21.6%. In utero diagnosis could prevent some diseases and in utero treatment is possible for hydrocephalus and hydronephrosis. Screening programs postnatally could lead to treatment. 5.9% were malignancies such as leukemia, lymphoma, brain tumors, histocytosis, Wilm's tumor, Ewing sarcoma, and Hodgkin's disease. Early diagnosis is critical if mortality is to be reduced in this group, but medical advances are still needed. 2.9% are miscellaneous diseases such as poisoning, rheumatic diseases, marasmus, Reye's syndrome, nephrosis, rickets, and epilepsy. Most of these diseases are preventable, except for rheumatic inflammation of the heart. Recommended necessary steps to reduce infant mortality are: prenatal care, diagnosis and screening, intrauterine surgery; resuscitation and intensive care centers with modern equipment and trained personnel; national vaccination and screening programs; adequate public health measures and hygiene; parental education; and well-equipped hospitals to serve all regardless of income level.

We analyzed infections complicating 140 episodes of severe neutropenia in 86 patients. The underlying diagnosis was acute leukemia in 64, lymphoma in 12 and isolated cases of bone marrow aplasia, agranulocytosis, dysmyelopoiesis and solid tumors. No fever developed in 35 (25%) episodes. No cause for the fever was identified in 40% of the remaining episodes. Clinical evidence of an infection was present in 20%, with positive bacteriologic findings in 27%. Respiratory infection (16%), pneumonia (11%) and sepsis (10%) were the most common infectious processes. Infectious agents isolated were gram negative bacilli (72%), gram positive cocci (19%) and fungi (9%). The association of amikacin and carbenicillin or cephalosporins proved to be superior to gentamycin-penicillin (p less than 0.01). 16 patients died for an overall mortality of 11%. Pneumonia and infection by K pneumoniae or C albicans were associated to a poorer prognosis.

The neuropathology of 18 cardiac transplant recipients was reviewed with the clinical findings. Pathological changes were noted in the central nervous system (CNS) in 94% of the patients, the most frequent being cerebral vascular in origin (72%). Eight patients (44%) had multiple cerebral infarcts and morphologically, a large number of these antedated the transplantation. In addition 4 patients had acute focal ischemic changes which occurred after transplantation. Intracranial hemorrhage was noted in 5 patients (28%), including one case of fatal intracerebral hemorrhage following an acute hypertensive episode after the transplantation. While systemic infection was common (10 patients), there were only 5 cases of intracranial infection; including 3 cases of cytomegalovirus infection, one of candidiasis and one of aspergillosis. Post-transplant seizures, occurring in a third of the patients, were related to a variety of causative factors such as sepsis, intracranial hemorrhage, cerebral ischemia, metabolic encephalopathy and cyclosporin neurotoxicity. Of note in this series was the absence of CNS lymphoma or other systemic lymphoproliferative disorder.

The clinical characteristics of 31 patients (pts.) (17 boys, 14 girls, median age 12 11/12 years) with large cell anaplastic lymphoma (LCAL) have been evaluated. 17 of these pts. had originally been diagnosed as suffering from "malignant histiocytosis" ("MH") and were therefore included in the DAL-Histiocytosis X 83 study. Another 14 pts. with Ki-1 lymphomas were enrolled in the BFM-NHL therapy studies. According to Murphyclassification 24 pts. (77%) had stage III or IV disease and in general presented in a severe condition. The lymphatic system was involved in 28 pts., 8 pts. (26%) had skin infiltration. With regard to lymphoma involvement of lung, bones and bone-marrow were unexpectedly frequent. CNS involvement was seen in just one pt. Despite rather heterogeneous therapy approaches (ALL-schedules, DAL-HX 83 protocol for treatment of "MH", combination of B-NHL-BFM and AML-BFM schedules, CHOP, BFM protocols for B-NHL) 30 out of 31 pts. achieved clinical remission (CR). The only nonresponder died during bone marrow transplantation of septicemia. 4 pts. relapsed during therapy. 3 of them died, 1 during a BMT. 1 pt. achieved 2nd CR with a BFM-B-NHL protocol. 3 pts. experienced a late relapse, 1 died, 1 2nd CR was achieved, the third pt. is still alive after 2 further relapses disease-free for 3 years. 23 pts. (74%, 13 out of 14 of BFM-NHL therapy study, 10 out of 17 of DAL-HX 83 study, 1 pt. after BMT) are in 1st CR with a median observation time of 2 9/12 years (range 5/12 to 17 9/12 years).(ABSTRACT TRUNCATED AT 250 WORDS)
