The female patient was diagnosed as having Von Gierke's disease at 14 years of age, based on clinical manifestations, laboratory examination and liver biopsy. At 19 years of age she had uremia and died from its deterioration at 24 years of age. The parents were consanguineous, and a 27-year-old sister is presently hospitalized for renal insufficiency with hepatomegaly. On autopsy, the patient's kidneys were highly contracted and contained a number of small cysts, mainly in the medulla. Histological examination indicated periglomerular fibrosis, glomerular hyalinization, tubular atrophy or cystic dilatation and intersitial fibrosis with round cell infiltration. These findings correspond to Fanconi's familial juvenile nephronophthisis, except for age. The liver was markedly enlarged and indicated severe, glycogen deposits, but the kidney did not contain glycogen deposits. It can, therefore, be presumed that the renal lesions were not a secondary consequence of long-term glycogen deposits but that renal and hepatic lesions were associated with each other.

A feline erythropoietic porphyria was studied in an affected female Siamese cat and 2 male offspring. The principal elevated porphyrins were Type I isomers of uroporphyrin and coproporphyrin; the porphyrin precursors, porphobilinogen and sigma-aminolevulinic acid, were also detected. Porphyrins were present in the blood and in all the viscera, teeth, bones, and excreta. There was severe macrocytic hypochromic anemia, hepatomegaly, splenomegaly, and uremia associated with a renal disease characterized by mesangial hypercellularity and proliferation (resulting in narrowing of glomerular capillaries) and ischemic tubular injury. There was thickening of tubular basement membranes and tubular epithelial lipidosis, degeneration, and necrosis. Electron microscopic studies of bone marrow and kidney revealed the presence of membrane-enclosed lamellar bodies 150 to 1000 nm in diameter in cytoplasmic and extracellular locations.

The clinicopathological features of a previously unrecognised type of acute encephalopathy prevalent among Japanese children is described by reviewing the records of 13 consecutive patients treated and 28 previously reported cases. The hallmark of this encephalopathy, proposed to be a novel entity termed acute necrotising encephalopathy of childhood, is multiple, necrotic brain lesions showing a symmetric distribution. The encephalopathy was noted in previously healthy children after respiratory tract infections, with presenting symptoms of coma, convulsions, vomiting, hyperpyrexia, and hepatomegaly. Laboratory examinations disclosed liver dysfunction, uraemia, and hypoproteinaemia. The histological appearance of the liver was variable and non-specific. Cerebrospinal fluid contained an increased amount of protein. Computed tomography and MRI showed the presence of symmetrically distributed brain lesions of the thalamus, cerebral white matter, brainstem, and cerebellum. Necropsy examination confirmed extensive fresh necrosis of these regions with evidence of local breakdown of the blood-brain barrier. Based on the characteristic combination of clinical and pathological findings, acute necrotising encephalopathy of childhood can be distinguished from previously known encephalopathies, including Reye's syndrome.

Monoclonal light chains (LCs) are responsible for a wide spectrum of renal and hepatic diseases, that above all include amyloid light-chain (AL) amyloidosis and light chain deposition disease (LCDD). Amyloid deposits stain for Congo red on light microscopy and have fibrillar aspect on electron microscopy, whereas deposits in LCDD are positive using monotypic LCs on immunofluorescence and have a granular aspect on electron microscopy. Sometimes fibrillar and granular deposits are observed in the same organ or in different organs of the same patient. Kidney and liver involvement is a frequent finding, both in primary amyloidosis (AL amyloidosis) or in LCDD. Renal manifestations include proteinuria, nephrotic syndrome, and progressive renal failure. End-stage renal disease requiring dialysis is observed in about 20% of patients with AL amyloidosis and in 70% of patients with LCDD. The mean survival time is about 12 to 18 months in AL amyloidosis and 34 months in LCDD. The most important prognostic factor is severe cardiac involvement, which reduces the mean survival to only 6 months. Hepatic manifestations include hepatomegaly, portal hypertension, ascites, intrahepatic cholostatic jaundice, and hepatic insufficiency. The mean survival of patients with liver damage is 14 months, but it is reduced to 5 months in patients with cholostatic jaundice. Contemporary kidney and liver involvement is usually observed on histologic examination, less frequently as clinical manifestation. No specific treatment exists for AL amyloidosis and LCDD, and the prognosis remains severe. The aim of treatment is to suppress proliferation of the abnormal clone of plasma cells and remove tissue deposits. The regimens, including melphalan-prednisone (MP) or vincristine-doxorubicin-dexamethasone (VAD), are used both in AL amyloidosis or in LCDD with some effectiveness. New approaches, especially the use of 4'-iodo-4'deoxydoxorubicin, could achieve better results. Dialysis seems to not worsen the outcome in both diseases because survival of patients on dialysis is not different from that of patients not reaching uremia. Also, kidney and liver transplantation is effective, though amyloidosis or LCDD may occur in transplanted organs. The most interesting therapeutic approach is autologous-blood stem-cell transplantation, which may produce a complete remission of the plasma-cell dyscrasia and a substantial improvement of clinical manifestations related to LC deposits.

A 73-year-old woman was presented with altered mental status and disorientation. She was diabetic and hypertensive, and she had experienced an ischemic cerebrovascular accident 3 years ago. Physical examination revealed the findings of chronic obstructive pulmonary disease, cor pulmonale and congestive heart failure. Hepatomegaly, splenomegaly and ascites were found and might be associated with postsinusoidal portal hypertension secondary to congestive heart failure. Laboratory tests showed uremia, lymphocytosis and thrombocytopenia. Neurologic findings were related with uremia and hypoxia. Multiple pathologic lymphadenopathies were seen in abdominal ultrasonography and thoracic computed tomography. Bone marrow histology indicated chronic lymphocytic leukaemia (CLL). The reason for acute renal failure was leukaemic infiltration of the kidneys due to CLL that was shown with renal biopsy. Blood urea nitrogen (BUN) and serum creatinine responded well to cyclophosphamide and methyl prednisolone treatment. In CLL, direct renal involvement is frequently seen in autopsy studies especially in advanced disease, however, renal failure due to leukaemic infiltration is extremely rare.

Thirty cases of autosomal dominant polycystic kidney disease (ADPKD) seen at King Fahd Hospital of the University, Al-Khobar over a period of eight years, were analysed with respect to clinical features, laboratory investigations, radiological findings, complications and outcome. There were 13 males and 17 females with a mean age of 45 yrs + 10.1 (range 16-65 years). There was positive family history of renal disease in 17 cases. At the time of presentation, 27 cases had abdominal pain. The other features noted were hematuria (20 cases), polyuria (10 cases), urinary tract infection (22 cases), headache (9 cases), uremia (7 cases) and nephrolithiasis (5 cases). Bilaterally palpable kidneys were present in all cases. Hypertension (17 cases) was the next common clinical finding. Other clinical features noted were hepatomegaly (5 cases) and mitral valve prolapse (5 cases). Twenty-one patients had cysts in liver and five had cysts in spleen. Varying degrees of renal failure were seen in 15 cases. Six (20%) patients progressed to end stage renal disease during the period of observation.

Constrictive polyserositis (pleuritis, pericarditis) is a syndrome within the underlying disease (tuberculosis, periodic disease, rheumatoid arthritis, systemic lupus erythematosus, asbestos, silicosis, uremia, some genetic diseases), a complication due to chest surgery or radiation or drug therapy, is occasionally idiopathic (fibrosing mediastinitis). There are frequently great difficulties in making its nosological diagnosis. The paper describes a patient in whom the onset of disease was exudative pleurisy with the signs of constriction, arthralgias; pleural punctures provided serous exudates with 80% lymphocytes. A year later there was ascitis and shin and foot edemas, which concurrent with hepatomegaly and cholestasis was regarded as cryptogenic liver cirrhosis. The signs of constrictive pericarditis were further revealed. The disease was complicated by the development of pulmonary artery thromboembolism (PATE) (which required the use of warfarin) and hemorrhagic vasculitis. Therapy with metipred in combination with isoniazid yielded a slight effect. The diagnoses of tuberculosis, liver cirrhosis, and autoimmune hepatitis, systemic vasculitis were consecutively rejected; the diagnosis of rheumatoid polyarthritis with systemic manifestations was made, by taking into account persistent arthalgias with the minimum signs of arthritis, noticeably increased C-reactive protein, rheumatoid factor, and cyclic citrullinated peptide antibodies (CCPA); plasmapheresis, therapy with metipred and methotrexate, and subtotal pericardectomy were performed. Constrictive polyserositis concurrent with PATE, hemorrhagic vasculitis (probably, drug-induced one), and hepatic lesion has been first described in a CCPA-positive patient with rheumatoid arthritis in the presence of moderate true arthritis (during steroid therapy).
