The records of eleven patients who underwent splenectomy for Gaucher's disease at The Mount Sinai Hospital from 1967 to 1981 have been reviewed. The major indications for operation were hypersplenism, pain, and mechanical problems associated with a massively enlarged spleen. There were no operative mortalities and the hematologic picture returned to normal in all cases. Because of the danger of overwhelming sepsis following splenectomy, partial splenectomy should be considered as a therapeutic modality in these patients.

Sixteen dogs with splenic infarction due to causes other than splenic torsion were identified. Dogs with splenic infarction often had multiple concurrent diseases, and surgical management of splenic infarction was associated with high mortality. Splenic infarction occurred in dogs with hypercoagulable conditions associated with liver disease, renal disease, and hyperadrenocorticism, or as a consequence of uniform splenomegaly, neoplasia, or thrombosis associated with cardiovascular disease. Clinical signs and common laboratory findings generally reflected the underlying disease process. A variety of splenic abnormalities were detected by abdominal ultrasound in 15 dogs, with the ventral extremity of the spleen being most often abnormal. Four dogs were euthanized or died because of the presence of severe systemic disease, whereas 12 dogs underwent laparotomy. Complete splenectomy was performed in 9 dogs and partial splenectomy was performed in 2 dogs. Seven dogs died in the immediate postoperative period, 3 required chronic veterinary care, and 2 had uncomplicated long-term recoveries. Splenic infaraction should be regarded as a sign of altered blood flow and coagulation, rather than as a primary disease, and surgical management should be reserved for patients with life-threatening complications such as hemoabdomen or sepsis.

A recent Ethiopian immigrant to Israel presented with pneumococcal sepsis, massive splenomegaly and lymph-adenopathy. Investigations revealed many features of both hairy cell leukaemia (HCL) and hyperreactive malarious splenomegaly (HMS). Proguanil therapy for HMS was followed by rapid, marked decrease in spleen size, disappearance of the tartrate-resistant acid phosphatase-positive cells characteristic of HCL, and increasing eosinophilia, but unchanged lymphadenopathy.

The traditional method of splenectomy involves a 7- to 10-cm abdominal incision, with its attendant morbidity that includes sepsis. Recently, the laparoscopic technique has been adopted for splenectomy. Many surgeons still believe that laparoscopic splenectomy should be carried out only for idiopathic thrombocytopenia purpura and Hodgkin's disease with a normal-sized spleen. A 16-year-old girl with marked splenomegaly (spleen size for times normal and weighing 600 g) due to congenital spherocytosis underwent laparoscopic splenectomy and retrieval of the spleen through the umbilical trocar site. Preoperative arterial embolization was not used, and the operative blood loss was estimated to be only 250 mL. Her postoperative course was uncomplicated, and she was discharged on the 4th postoperative day. The operative technique is described and the advantages of laparoscopic splenectomy are discussed.

We review the clinical manifestations and long-term outlook of patients with chronic natural killer (NK) cell lymphocytosis. After reviewing more than 1,500 peripheral blood lymphoid flow cytometry reports and molecular genetics data from patients with suspected large granular lymphocyte (LGL) proliferation, we identified 10 patients (median age at diagnosis, 60 years; range, 35 to 76 years; male:female ratio, 3:2) with persistent (greater than 6 months) increase in phenotypically determined NK cells (CD3-CD16+). Southern blot analysis performed on 9 patients showed no clonal T-cell receptor gene rearrangements. Disease duration was measured from time of initial recognition of LGL or NK cell excess (greater than 40% of the lymphocyte fraction). Clinical data from these 10 patients were compared with those from 68 patients with T-cell LGL (T-LGL) leukemia. Currently, all patients are alive (median disease duration, 5 years; range, 0.8 to 8 years). Associated disease manifestations included pure red blood cell aplasia, recurrent neutropenia, recurrent neutropenic sepsis, and vasculitic syndromes, all of which were responsive to immunosuppressive therapy. No patient had palpable lymphadenopathy or splenomegaly. Compared with the patients with T-LGL leukemia, patients with chronic NK cell leukemia has similar lymphocyte counts, associated conditions, treatment responses, and survival but had less neutropenia and anemia.

Life-threatening portal hypertension (PHN) in patients with chronic myeloproliferative disorders may result from increased portal flow caused by marked splenomegaly or an increased resistance to portal flow from either a large vein thrombosis or an intrahepatic obstruction usually associated with agnogenic myeloid metaplasia (AMM). The former cause is correctable by splenectomy alone, whereas the latter requires portal-systemic shunt surgery. Few data exist regarding the outcome of portal-systemic shunt surgery in patients with AMM and intrahepatic obstruction. During the past 25 years, 13 patients with chronic myeloproliferative disorders underwent portal-systemic shunt surgery at our institution. The cause of PHN was intrahepatic obstruction in ten patients and hepatic vein thrombosis in three. Ten of the thirteen patients had AMM as initial diagnosis. Only one patient had intraoperative complications, and four patients had either sepsis or thrombosis during the postoperative period. Twelve patients survived the postoperative period and had a median postsurgical survival of 3 years (range, 0.25 to 19 years). The long-term complications of the operation were very few and included hepatic encephalopathy (one patient), portal vein thrombosis (one patient), and shunt occlusion (one patient). The procedure was successful in alleviating complications of PHN in all but one patient. Deterioration of hepatic function and subsequent hepatomegaly were unusual. Portal-systemic shunt surgery seems to be a useful option in patients with AMM and life-threatening PHN from intrahepatic obstruction.

Hypersplenism is defined as the association of anemia, leukopenia, or thrombocytopenia with bone marrow hyperplasia and splenomegaly. Hypersplenism is common in liver cirrhosis and frequent in patients with portal hypertension. The effects of portacaval shunt are variable; hypersplenism hardly ever improves but rarely develops after surgery. Since the spleen is a major component of the mononuclear phagocyte system, splenectomy reduces antibody synthesis. Although splenectomy abolishes hypersplenism, it may lead to sepsis. Recently, partial splenic embolization, using gelform injected directly into the splenic artery, has been performed in patients with cirrhosis. Partial splenic embolization induces an increase in the number of circulating blood cells. In addition, the levels of albumin, hepaplastintest, cholesterol and cholinesterase are increased significantly after treatment. Partial splenic embolization rarely causes problems and may actually be beneficial.

Eighty-two consecutive cases of acute leukaemias in adult Ethiopians were admitted to the Tikur Anbessa (Black Lion) Hospital, a teaching and referral hospital in Addis Abeba, Ethiopia, from January 1982 to December 1992. These cases were studied to describe the clinical and haematological findings, response to therapy and prognosis. The age range was 13-78 (mean 29.6) years. The male to female ratio was 1.6:1. Acute myeloblastic (AML) and acute lymphoblastic (ALL) leukaemias occurred in 53.7% and 46.3%, respectively. The commonest symptoms were anaemia, fever and bleeding tendencies. The commonest signs were pallor, fever, sternal tenderness and purpura. Splenomegaly was more commonly seen in ALL patients. The haematological findings were anaemia (mean Hgb 6.35 g%), leucocytosis (mean WBC count 88,507/mm3) and thrombocytopenia (mean platelet count 31,700/mm3). Of the patients eligible for evaluation treated with chemotherapeutic agents, only 38.4% of ALL and 6.2% of AML achieved complete remission. Twenty-seven patients with ALL died from one day to 84 (median 1.0) months after diagnosis. Ten are lost to follow-up from two weeks to 36 (median 2.5) months, one is still alive 40 months after diagnosis. Thirty-nine of the AML patients died from one day to nine (median 0.3) months after diagnosis. Five are lost to follow-up from two weeks to two and a half (median 2.0) months. The causes of death were sepsis and bleeding, separately or in combination. Increasing numbers of acute leukaemia patients are being referred to this centre. Therefore, attempts should be made to equip it for the treatment of such cases.

We retrospectively examined the medical and autopsy records of seven previously unpublished cases of fatal pneumococcal septicemia in children with hemoglobin SC disease. The earliest death occurred in a 1-year-old child who had congenital heart disease with cyanosis; the other children were aged 3 1/2 to 15 years. Only one child had received pneumococcal vaccine or prophylactic penicillin therapy. All seven children had an acute febrile illness and rapid clinical deterioration despite parenterally administered antibiotic therapy and intensive medical support. Erythrocyte pit counts in two patients were 40.3% and 41.7%, respectively (normal, < or = 3.6%). Autopsy data from five cases showed marked splenic congestion without infarction in five, splenomegaly in four, and bilateral adrenal hemorrhage in three. These cases illustrate that functional asplenia predisposes some children with hemoglobin SC disease to the development of fatal septicemia after the age of 3 years. We conclude that pneumococcal vaccine should be administered to all children with hemoglobin SC disease and that acute febrile illnesses should be investigated promptly for the possibility of septicemia. The routine use of prophylactic penicillin therapy in infants and children with hemoglobin SC disease remains controversial.

A follow-up study of 179 cases of human immunodeficiency virus (HIV) seropositive neonates born from HIV seropositive mothers is reported. At the time of the present study, HIV infection resulting from maternofetal transmission was found in 50 cases, while 108 infants were not infected; HIV infection remained uncertain in 16 cases; 5 infants were lost for follow-up. Out of the 50 infected cases, 20 were less than two-year old, 17 were 2-5 year old and 13 were older than 5 years. Very few remained asymptomatic after the age of 6 months, the most common symptoms being adenopathies and/or hepatomegaly and/or splenomegaly. Twenty-six had an acquired immunodeficiency syndrome (AIDS). Six died, from pneumocystosis (3), cytomegalovirus infection (1) and septicemia (2). Virus culture and polymerase chain reaction were the most efficient laboratory methods for early diagnosis of HIV infection, both being positive in more than 95% of the infected cases after the age of 3 months. A close clinical and biological supervision is recommended in these infants and children because of the permanent threat of infectious diseases in relation to their immunodeficiency. Treatment associates: 1) antiviral therapy with AZT as soon as the HIV infection is diagnosed; 2) primary prophylaxis against pneumocystosis with trimethoprim-sulfamethoxazol; 3) IV immunoglobulins in the case of repeated bacterial infection; 4) regular evaluation of the nutritional status and psychological assistance.(ABSTRACT TRUNCATED AT 250 WORDS)
