Two patients with left recurrent laryngeal nerve paralysis in association with pulmonary artery hypertension are described. One had primary pulmonary hypertension and the other had patent ductus arteriosus. The greatly dilated pulmonary artery in these patients resulted in compression of the left recurrent laryngeal nerve and produced a cardiovocal (Ortner's) syndrome. The pathogenesis of the vocal cord palsy was documented by cross-sectional computed tomography. In conclusion, computed tomography is of great help in differentiating this syndrome from other diseases such as mediastinal mass or lymphadenopathy whenever hoarseness is complicated by pulmonary hypertension.

Although ganglioneuroblastomas occur infrequently in the head and neck area, if they are recognized and completely excised initially, the chances of cure are greatly increased. Two patients are reported who demonstrate some of the more important aspects of diagnosis and treatment. The first patient, whose retropharyngeal tumor was diagnosed when he was 12 years of age, was treated with transoral excisional biopsy. He is alive and tumor-free 3 1/2 years later. The second patient, a 2-year-old , was treated by incisional biopsy without a major resection. He died on year later. The diagnostic evaluation of a patient with suspected neurogenic tumor includes a complete physical examination for distant adenopathy, abdominal masses, hypertension, and neurological impairment. Intraoperatively, neurosurgical and pathological consultation should be available.

Over 100 cases of disorders closely resembling classic autoimmune diseases have been reported among patients who were injected or implanted with a diverse group of chemicals including paraffins, vegetable oils or silicone. Most cases have occurred in silicone breast implant recipients, especially those who received their prostheses 2-10 years prior to onset of symptoms. A high proportion of patients exhibit classic signs and symptoms of Sjogren's syndrome or scleroderma. Affected patients typically experience some combination of fatigue, myalgia, joint pain, sicca syndrome (dry eyes and mouth), synovitis, rash, alopecia, muscular weakness or lymphadenopathy, and autoantibody formation. Less commonly, patients may have the CREST syndrome (calcinosis, Raynaud's phenomena, esophageal hypomotility, sclerodactyly and telangiectasias), hypertension, pulmonary fibrosis, or central nervous system pathology.

The clinical and immunological manifestations of 51 children with onset of systemic lupus erythematosus (SLE) before the age of 15 were compared with those of 308 adult patients with disease onset between the age of 15-49 and another 27 elderly lupus patients whose disease onset occurred at or after the age of 50. Overall disease activity determined by mean SLEDAI score was highest in the childhood group followed by the adult and the elderly group respectively. More severe form of cutaneous involvement, adenopathy, hypertension, renal involvement with renal insufficiency and anti-nDNA antibodies occurred predominantly in the childhood lupus. The clinical features distinguishing old-age lupus were chronic disease with a long interval between the time of onset and diagnosis, higher incidence of discoid rash and lower incidence of malar rash and renal involvement. Frequencies of anti-nDNA antibodies and renal involvement gradually decreased from childhood, to adulthood and to elderly lupus respectively. Anti-Sm antibodies were predominant in the adult onset group. Genetic markers, sex hormones and senility of the immune system may play a role in these age-related differences in clinical and immunological manifestations in SLE.

At the core of chronic venous insufficiency (CVI) is valvular incompetence affecting the large veins, which results in ambulatory venous hypertension. Recent research has revealed the pathophysiological stages involved: damage to the endothelium of the vein, leukocyte trapping and, finally, inflammatory reconstruction of the vessel wall. Lymphangiopathy involving the small and large lymph vessels is always present. One of the measures capable of influencing elevated venous pressure is compression therapy, which is discussed in detail in the present article. Drug treatment is a rational supplement to curative therapeutic approaches to chronic venous insufficiency that in mild-to-moderate cases, can result in an alleviation of symptoms similar to that achieved with compression therapy.

The sudden onset of hypertension mandates investigation for secondary causes. We report the case of a young man with a very rare systemic fungal disease that included massive unilateral perirenal adenopathy. Treatment was associated with the abrupt onset of severe hypertension. Imaging studies suggested progressive constriction of one kidney with treatment, presumably as a result of healing adenopathy. We suggest that this case is a new example of hypertension secondary to constrictive perinephritis (Page kidney).

We report a case of mantle cell lymphoma in leukemic phase, which was diagnosed by a bone marrow biopsy performed as part of a workup for chronic anemia in a patient without lymphadenopathy. The patient, a 79-year-old man with diabetes mellitus, hypertension, chronic renal failure, congestive heart failure, and atherosclerosis, presented with claudication. On admission, he also had an 8-month history of anemia, during which time he experienced a 18-kg weight loss. On presentation, the patient had normal vital signs, anemia, leukocytosis (as well as an absolute lymphocytosis), and splenomegaly; as mentioned, lymphadenopathy was absent. A bone marrow biopsy showed an increase in small to intermediate-sized, slightly irregular lymphocytes in interstitial nodules. Flow cytometric immunophenotyping of the bone marrow identified a monoclonal population of cells, representing 25% of cells within the bone marrow, with expression of CD19, CD20, immunoglobulin M/D, lambda light chain, HLA-DR, and CD5; reactions for CD10 and CD23 were absent. Based on morphologic and immunophenotypic analysis of the bone marrow, as well as morphologic review of the peripheral blood smear, a diagnosis of mantle cell lymphoma involving the bone marrow and in leukemic phase was made. Subsequent polymerase chain reaction analysis of DNA from peripheral blood identified a population of cells with the bcl-1 rearrangement. This case is unique in that the diagnosis of mantle cell lymphoma was made without lymph node or spleen analysis and the patient, although exhibiting bone marrow and peripheral blood involvement by mantle cell lymphoma at presentation, did not have lymphadenopathy.

Charts of 180 patients (147 women, 33 men) with systemic lupus erythematosus (SLE) complicated by renal involvement were retrospectively analyzed from a series of 436 patients. Mean age at renal disease onset was 27 years. Thirty-six percent of the patients had renal involvement after diagnosis of lupus, for 30.7% of that group it was more than 5 years later. Renal involvement occurred more frequently in young male patients of non-French non-white origin. Patients with renal involvement suffered more commonly from malar rash, psychosis, myocarditis, pericarditis, lymphadenopathy, and hypertension. Anemia, low serum complement, and raised anti-dsDNA antibodies were more frequent. According to the 1982 World Health Organization classification, histologic examination of initial renal biopsy specimen in 158 patients showed normal kidney in 1.5% of cases, mesangial in 22%, focal proliferative in 22%, diffuse proliferative in 27%, membranous in 20%, chronic sclerosing glomerulonephritis in 1%, and other forms of nephritis in 6.5%. Distribution of initial glomerulonephritis patterns was similar whether renal involvement occurred before or after the diagnosis of lupus. Transformation from 1 histologic pattern to another was observed in more than half of the analyzable patients (those who underwent at least 2 renal biopsies). Nephritis evolved toward end-stage renal disease in 14 patients despite the combined use of steroids and cyclophosphamide in 12. Initial elevated serum creatinine levels, initial hypertension, non-French non-white origin, and proliferative lesions on the initial renal biopsy were indicators of poor renal outcome. Twenty-four patients died after a mean follow-up of 109 months from SLE diagnosis. Among our 436 patients, the 10-year survival rate was not significantly affected by the presence or absence of renal involvement at diagnosis (89% and 92%, respectively).

Diagnosis is central to medicine. In spite of tremendous diagnostic technological advances, no infallible test exists and in the complex diagnostic process the physician may well get lost. The ultimate feedback on the accuracy of diagnosis is the autopsy. Five patients illustrate that the autopsy may disclose unexpected results. The first patient was a 9-year-old girl who suffered from daily abdominal spasmodic pain but each time recovered. She died suddenly; autopsy revealed intestinal intussusception. A 46-year-old man who was treated for hypertension developed pain in the chest and the lower back, but there were no other signs of myocardial infarction. He died suddenly; autopsy revealed a dissecting aortic aneurysm with rupture in the left pleural cavity. A 21-year-old woman, an excellent swimmer, drowned during a swim in the sea. Autopsy revealed severe widespread coronary disease with multiple myocardial infarction. A 32-year-old Surinam woman developed acute coma and died from cardiorespiratory arrest. At autopsy she had massive pulmonary embolism and generalized lymphadenopathy due to sarcoidosis. The last patient, a 32-year-old woman suffered from fatigue after her fourth child was born. She was admitted with severe dyspnoea and her chest X-ray showed interstitial fibrosis. She died presently and autopsy revealed metastatic colon carcinoma with pulmonary lymphangitis carcinomatosa. Systematic reviews of the results of autopsies show no decline in the percentage of false diagnoses and/or unexpected findings in spite of the enormous growth of the diagnostic armamentarium. Although we may radiologically 'slice' the body in incredible detail or investigate human cells at the molecular level, the autopsy has by no means become obsolete and is an invaluable tool for quality control and teaching.

One hundred and one donors who had received filgrastim (rhG-CSF) for the purpose of donating either granulocytes or peripheral blood stem cells (PBSC) for their relatives more than 3 years ago were contacted. All donors had received daily rhG-CSF at a median dose of 16 microg/kg/day (range 3-16) for a median of 6 days (range 3-15 days). All collection procedures were completed and short-term side-effects of rhG-CSF were mild in the majority of the donors. At a median time interval of 43.13 months (range 35-73), the donors were contacted to assess whether adverse effects related to rhG-CSF administration had occurred. Prior to rhG-CSF two donors had cancer, one had a myocardial infarction, one was hepatitis C virus positive, one had a history of sinusitis, one had Graves' disease and two had arterial hypertension. None worsened with the rhG-CSF administration but the donor with a history of infarction had an episode of angina following apheresis, and the donor with Graves' disease had a stroke 15 months after rhG-CSF. Two pregnancies occurred after the rhG-CSF administration and one donor was 2-3 weeks pregnant during rhG-CSF treatment. Three pregnancies resulted in two normal births and one in a spontaneous abortion of a pregnancy which occurred more than 2 years following rhG-CSF. In the time following rhG-CSF administration two donors developed cancer (breast and prostate cancer) at a follow-up of 70 and 11 months, respectively. One donor developed lymphadenopathy 38 months after the rhG-CSF, which spontaneously resolved. Blood counts were obtained in 70 donors at a median follow up of 40.4 months (range 16.8-70.8). Hematocrit was 43% (median, range 36.8-48), white blood cells were 5.7 x 109/l (median, range 3-14), granulocytes 3.71 x 109/l (median, range 1. 47-10.36), lymphocytes 1.67 x 109/l (median, range 0.90-3.96), monocytes 0.46 x 109/l (median, range 0.07-0.87) and platelet counts were 193.0 x 109/l (median, range 175.0-240.0). This study indicates that short-term administration of rhG-CSF to normal donors for the purpose of mobilizing the PBSC or granulocytes appears safe and without any obvious adverse effects more than 3 years after the donation. Bone Marrow Transplantation (2000) 25, 85-89.
