A case of an encapsulated organizing hematoma of the sciatic nerve is reported. Hemorrhage-induced neuropathy as a complication of anticoagulant therapy, leukemia, hemophilia, and other bleeding diatheses has been frequently reported. While trauma is the most common etiology of a hemorrhagic neuropathy, actual hematoma formation beneath the epineurium is very rare.

32P is effective therapy for polycythemia and primary thrombocytosis. The Polycythemia Vera Study Group is comparing radioactive phosphorus with alkylating agents to determine relative efficacy. Less well investigated is the effectiveness of 32P vs. busulfan in chronic granulocytic leukemia. Endolymphatic administration of radiopharmaceuticals may play a role in the therapy of infradiaphragmatic lymphoma. Among the radionuclides that have at times been used in hematology are 32P, 198Au 24Na, 76As, 89Sr, 52Mb, 54Mn, 91Y, 95Zr, 95Cb, 111Ag, 109Pd, 131I, 185W, and 192Ir. As stated, 32P has proven single most efficacious agent. The hematologic diseases that have been treated include both malignant and benign conditions. Among the malignant conditions are polycythemia vera, agnogenic myeloid metaplasia, thrombocythemia, leukemia, Hodgkin's disease, and multiple myeloma. Hemophilia, and Osler--Weber--Rendu disease are among the benign entities in which the agents have been tried. Polycythemia and thrombocythemia remain those in which the greatest success has been achieved.

Nine cases have been presented in detail to illustrate some of the varied causes of sudden neurological deficit in childhood: arteriovenous malformation, cryptic hamartoma, berry aneurysm, mycotic aneurysm, intraspinal arteriovenous malformation, brain tumor, migraine, arteritis, and multiple sclerosis. The Boston Children's Hospital experience with aneurysms and intracranial arteriovenous malformation has been summarized. It is noteworthy that a cutaneous hemangioma overlay one cranial and one intraspinal arteriovenous malformation. One small but deep cerebral arteriovenous malformation apparently destroyed itself after its second hemorrhage. Not only have multiple sclerosis and a brain tumor mimicked a vascular lesion, but a series of vascular accidents was misdiagnosed first as multiple sclerosis then as a thalamic tumor. The many possible causes of childhood strokes has been thoroughly cataloged in the Report of the Joint Committee for Stroke Facilities in 1973 (11). Children may be more susceptible to strokes because of congenital abnormalities such as congenital heart disease, hemophilia, and sickle cell anemia, or by diseases which more commonly occur in this age group, such as leukemia. The likelihood of brain abscess in cyanotic congenital heart disease is stressed. Arteriographic studies in our series have been safe; however, there have been reports of probable worsening of symptoms in children with multiple cerebral occlusive lesions in the presence of homocystinuria.

Hemophiliacs often have mild anemia, and hemolysis has been suggested as the likely mechanism on the basis of the reduced serum haptoglobin values frequently observed in these patients. It has been suggested that hypohaptoglobinemia results from isohemagglutinins or other contaminating proteins in the infused factor concentrates. The advent and increased utilization of Factor VIII concentrates that are highly purified by use of monoclonal antibodies have provided the opportunity to study whether proteins other than Factor VIII contained in the concentrate induce hemolysis. Of 49 consecutively studied Factor VIII-deficient hemophiliacs, 19 (39%) had a reduced serum haptoglobin level (less than 27 mg/dl). In particular, 16 of 35 (46%) of patients receiving only monoclonally purified Factor VIII products (Monoclate or Hemofil-M) had a reduced serum haptoglobin value. Haptoglobin measurements were variable on repeat measurement in 8 patients. Haptoglobin levels did not correlate with type or severity of hemophilia, hemoglobin value, or alterations in liver function. Low serum haptoglobin values were also observed in children with leukemia, without apparent hemolysis, who had extensive cutaneous hemorrhage associated with thrombocytopenia. We propose that reduced serum haptoglobin values in hemophiliacs do not result from immune-mediated hemolysis due to contaminating proteins in the concentrate. Moreover, hypohaptoglobinemia may not be due to hemolysis at all but may instead result from dissolution of hematomas and other foci of internal hemorrhage.

Children with blood diseases do not infrequently visit the dental clinics. Therefore, it is important to recognize the actual condition of blood diseases in association with the oral treatment of patients. During the period from Sept. 1979 to June 1989, 68 patients who had blood diseases visited the Pedodontic Clinic of Niigata University Dental Hospital. This report is the investigation of the dental situation of these patients. The result were as follows: 1. The ratio of patients with blood diseases in our clinic was 0.7%. The patients with leukemia were most frequent. 2. Most of the first visit-patients with blood diseases were children aged 6, while the general patients group was younger. The ages of first visit-patients corresponded to the most frequent ages of primary diseases. 3. The majority of their chief complaints were "the treatment of decayed teeth for caries". Others were "the extraction of loose teeth for exchange" or "the diseases of oral soft tissues". 4. The patients visited our clinic from all over Niigata prefecture, some of which visited from a great distance and were introduced by Niigata University Medical Hospital. 5. As to the treatment of decayed teeth for caries, the patients with hemophilia had a large number of treated teeth as compared with the other diseases. In case of leukemia, anaphylactoid purpura and idiopathic thrombocytopenic purpura (ITP), the outpatients generally tend to be subject to more severe caries than the inpatients in Niigata University Medical Hospital. 6. The percentage of recall of patients with blood disease was lower than that of general children at the rate of about 20%.(ABSTRACT TRUNCATED AT 250 WORDS)

Eight hundred and fifty two cases, who were introduced from the Dental Hospital to Department of Internal medicine, Medical Hospital at Niigata, The Nippon Dental University, were examined for medical complications. About one hundred and fifty cases were introduced per year from the Dental Hospital, which consisted of about 15% of the total outpatients in the Department of Internal medicine. The age distribution showed a high incidence of patients in their 50's. The number of patients over 60 years old was 220 (25.8%), and the number of patients over 65 years old was 160 (18.8%). There was then a high percentage of elder patients. The reason for the initial medical examinations was the need for a pre-operative medical examination in 42.6% of the total cases. Concerning medical complications among the patients, the highest incidence was hypertension in 116 cases (13.6%); the second highest was hepato-biliary and pancreatic diseases in 114 cases (13.4%); and heart diseases in 81 cases (9.5%). Eighteen cases of HBs antigen positive (2.1%) were seen among the patients with liver diseases. Among those with blood diseases, anemia showed the highest incidence, and a small number had leukemia and hemophilia. Diabetes mellitus showed up in 39 cases (4.6%), most of them being more than 40 years of age. Mentally and physically handicapped patients accounted for 30 cases. Half of them were from the pre-operative examination area, like tooth extraction.

In 21 patients with haemophilia, 10 with acute leukaemia, 12 with malignant lymphomas, and 12 with multiple myeloma in whom the risk of viral infection is increased the following antibodies were determined: anti- CMV, anti-HIV, anti-HBs, and HBs antigen by ELISA test. Anti-CMV were found mainly in acute leukaemia (90%), in haemophilia (71.4%), in malignant lymphoma (41.7%) and multiple myeloma (33.3%). In 19% of cases of haemophilia anti-HIV antibodies were present. In other groups these antibodies were not found. In acute leukaemias mostly anti-HBs antibodies were present. The group of haemophiliacs is particularly exposed to infection by these viruses which is connected unquestionably to blood transfusions.

We report the cases of 38 children with transfusion-associated HIV infection: 18 hemophiliacs and 2 patients with Von Willebrand disease, 6 with hemoglobinopathies, 8 with malignant diseases or aplastic anemia, 2 transfused during neonatal period and 2 during a surgical operation. Two groups with a different prognosis were found: In group A [hemophilia and Von Willebrand disease (n = 20)] 17 patients were asymptomatic or only with lymphadenopathy; 3 reached stage IV and none died. In group B [Others (n = 14)] 2 patients were asymptomatic, 4 reached stage IV and 8 died, 4 of them directly from AIDS. The difference between both groups was statistically significant. Prognosis of HIV infection is particularly severe in patients with leukemia, malignant tumors and aplastic anemia.

The specific emphasis in this article has been directed toward the diagnosis of prevalent shoulder pathology in a young athletic population; however, as the interest in sports has blossomed in recent years now encompassing a larger age range, the physician must not neglect common pathologic conditions of the older athletes. Fastidious adherence to complete history, physical examination, and a high level of suspicion for uncommon disorders is paramount. Arthritides such as osteo, rheumatoid, septic, and lyme as well as the hematologic disorders of multiple myeloma, lymphomas, leukemia, hemophilia, and Gaucher's disease can all present with shoulder pain. Thoracic outlet syndrome, scalene syndrome, supra-scapular nerve syndrome, and quadrilateral space syndrome comprise a group of nerve compression syndromes that are becoming more apparent as our diagnostic skills improve. Yet, the most pervasive disorders in the young athlete are due to lack of shoulder stability. By understanding the delicate balance in normal shoulder between mobility and stability, the clinician is better able to conceptualize the etiology and progression of the problem, and design the optimal treatment program.

The third member of the family of T cell leukemia viruses (HTLV III) has been proposed as the primary etiologic agent of the acquired immunodeficiency syndrome (AIDS). A high risk of AIDS has been reported among patients with hemophilia, particularly those with factor VIII deficiency who receive commercial clotting factor concentrates. In a prevalence survey conducted between September 1982 and April 1984, initial serum samples from 74% of hemophiliacs who had ever been treated with commercial factor VIII concentrate, 90% of those frequently treated with factor VIII concentrate, and 50% of those treated with both factor VIII and factor IX concentrates had antibodies reactive against antigens of HTLV III, compared with none of the hemophiliacs treated only with factor IX concentrate or volunteer donor plasma or cryoprecipitate. Two of the seropositive patients have developed AIDS-related illnesses, and a third patient died of bacterial pneumonia. One initially seronegative patient developed antibodies against HTLV III during the study and is currently well. The predominant antibody specificities appear directed against p24 and p41, the presumed core and envelope antigens of HTLV III, suggesting that factor VIII concentrate may transmit the p24 and p41 antigens of HTLV III. However, the presence of infectious retroviruses in clotting factor concentrates and the effectiveness of screening and viral neutralization procedures remain to be determined.
