A herd of cattle which produces calves with generalised glycogenosis type II has been established. Seven affected animals have been born and their disease status as indicated by a decreased acid alpha-glucosidase activity and excessive glycogen deposition in muscle, can be detected on the day of birth. Two animals have died of heart failure aged 3 and 5 months and have shown cardiomegally. Five animals were clinically normal until 9 months of age when they failed to maintain weight gain, showed muscle weakness and four were killed aged between 12 and 16 months after showing difficulty in rising. All affected animals had abnormal ECG tracings and had elevated levels of CK, LDH and HBDH in serum. Excessive amounts of glycogen were deposited in voluntary, cardiac and smooth muscle, and in cells of the nervous system. The muscles showed a vacuolar myopathy. Both the infantile and late onset forms of generalised glycogenosis type II are present in this herd of cattle. The condition appears to be controlled by a recessive allele at a single autosomal locus.

Hypokalemic myopathy has been observed in various clinical conditions. There are many studies of the pathomorphological changes of muscle fibers but alterations in intramuscular nerves and motor end-plates are seldom mentioned. The present authors observed biopsied muscle from a 51-year-old housewife who had suffered from gradually increasing muscle weakness. Laboratory examinations revealed a severe hypokalemia of 1.5 mEq/1, 18304 U/1 of CPK, 1300 U/1 of LDH, 343 U/1 of SGOT and 297 IU/1 of adolase. Light-microscopic examination showed changes previously described, including twin-peaked distribution in the histogram of type I, IIA and IIB fibers, ballooning and thickening of terminal axon, and 2 or 3 end-plates closely spaced along the length of muscle fibers. The electron-microscopic examination revealed empty folds of basement membrane in end-plate regions, reduced secondary synaptic clefts, interposition of Schwann cell processes between nerve ending and primary synaptic cleft, and an increase of disarranged microtubules and neurofilaments in terminal axons. The findings suggest that severe hypokalemia primarily produces structural alterations of intramuscular peripheral nerves and motor end-plates as well as of muscle fibers.

A 50-year-old man was admitted to our hospital, because of weakness in his right leg. On admission, he had generalized hyperreflexia and positive Babinski signs bilaterally. After admission, weakness in his left leg and confusion developed. A cerebrospinal fluid examination revealed increases in cell counts and protein but was negative for malignant cells. Blood chemistry was normal except for elevated LDH. A bone marrow biopsy yielded lymphoma cells. Successive T2-weighted cranial MRI showed a progressively expanding high signal area in the right parieto-occipital lobe. His confusional state improved after chemotherapy; however, two months later another cranial CT showed multiple enhanced mass lesions. The patient died 20 months after the onset of illness. Postmortem examination revealed widespread intravascular aggregates of malignant lymphomatous cells in the cerebrum, lungs and kidney, as well as multiple infarcts without atherosclerosis in the cerebrum. These pathological findings are compatible with those of intravascular malignant lymphomatosis. In addition, extravascularly expanding tumor cells formed multiple nodular lesions in the cerebral hemisphere. An immunohistochemical study showed that the tumor cells were positive for B-cell marker L26. Intracranial lymphomatous mass lesion rarely occurs in cases of intravascular malignant lymphomatosis. In the present case, tumor cells were presumably restricted to intravascular spaces, occluded them and resulted in ischemic lesions in the cerebrum in the early phase, but they expanded extravascularly and developed mass lesions in the terminal stages. In conclusion, intravascular malignant lymphomatosis is considered to be phenotypes of malignant lymphoma. This is the first case of intravascular malignant lymphomatosis associated with intracranial lymphomatous mass lesions in Japan.

A 78-year-old man was hospitalized because of muscular weakness and acute renal failure. He had been taking glycyrrhizin (280 mg/day) for the last 7 years. Hypertension was noted in his history. Serum potassium was 1.9 mEq/l with metabolic alkalosis. There was hyporeninemic hypoaldosteronism. Serum enzymes, including GOT, LDH and CPK were markedly elevated. In addition, serum myoglobin was as high as 46 micrograms/ml with massive myoglobinuria. Oliguria occurred and blood urea nitrogen and serum creatinine rapidly elevated from 20.9 to 87 mg/dl and from 1.3 to 6.7 mg/dl, respectively. Profound calcium deposition was found in the damaged skeletal muscles, including the quadriceps femoris, axillar, neck, and cardiac muscles. These results indicate that licorice-induced pseudoaldosteronism produces hypokalemic rhabdomyolysis, resulting in acute renal failure and profound deposition of calcium into the damaged skeletal and cardiac muscles.

We report a 55-year-old man with papilledema and multiple cranial nerve palsies. He was well until 52 years of age when there was an onset of progressive difficulty in initiating urination; he visited the urology service of our hospital where a diagnosis of prostate cancer was made; the cancer was invading the bladder and was metastasizing to lymph nodes and bones. He was treated with oochiectomy and estrogen preparations with some improvement in his symptoms. Two years later, he developed difficulty in urination again, and transurethral resection of the tumor was performed in 1991. In December 1991, he noted tingling and numb sensation in his left face, which had become progressive worse within the next one month, and he developed blepharoptosis and deafness all on the left side. He was admitted to the urology service on February 4, 1992, and a neurological consultation was asked. On physical examination, general findings were unremarkable, except for lymph node enlargements of about 0.5 to 1.0 mm in size in cervical and inguinal regions. On neurologic examination, he was alert with normal mental activities; higher cerebral functions were intact. He had normal vision and visual fields, however, papilledema was present bilaterally; pupils and light reactions were normal. Extraocular muscles were intact on the right side, however, moderate restriction was noted in the left eye in that all the extraocular muscles except for the medial rectus were weak; blepharoptosis was noted on the left; no nystagmus was present. The sensation was diminished in the left face, and left facial paresis of the peripheral type was also noted; the taste sensation was also diminished in the left anterior two thirds of the tongue. He had sensorineural deafness on the left side. The other cranial nerves appeared intact. He walked normally; no weakness or muscle atrophy was noted; muscle tone was normal and no ataxia was observed. Deep reflexes were normally elicited and symmetric; the plantar response was flexor. No meningeal signs were present. Laboratory examination revealed following abnormalities: Hb 7.1 g/dl, platelet 47,000/cmm, WBC3,800/cmm, LDH 950IU/l, PAP232ng/ml (normal less than 1.6), PA2.631ng/ml (normal less than 7.4); a small amount of effusion was noted in the left pleural cavity; cytological examination of the fluid was class V. A cranial CT scan as well as MRI were entirely normal, as was the spinal tap. He was treated with glycerol, however, there was progressive increase in the pleural effusion, and he developed dyspnea; moist rale had become audible in the end of February.(ABSTRACT TRUNCATED AT 400 WORDS)

We report a 62-year-old man with a pelvic mass, who developed multiple cranial nerve palsies on the right side. He was well until the summer of 1977 when he developed a numb sensation in the sacral region. In the next year, a huge tumor was found in the sacral area in another hospital. Most of the tumor was resected at that time. Post-operative course was uneventful. In July 1988, there was an onset of weakness in his legs, gait disturbance, and dysuria. Myelography at the above hospital revealed a complete block at the seventh thoracic level. He was treated by laminectomy and post-operative radiation. In June 1990, he developed a neuralgic pan in his right leg. Two months later, he noted diplopia, deafness in his right ear, and swallowing difficulty. He was admitted to our hospital for further work up on January 14th of 1991. On admission, he was afebrile. General physical examination revealed a 4 cm had mass in his right anterior chest attaching the rib. Gynecomastia was noted bilaterally. Liver was felt by 5 cms under the right hypochondrium. The edge of the liver was firm. On neurologic examination he was an alert and mentally sound man. His higher cerebral functions were intact. In the cranial nerves, complete palsy of the abducens nerve, mild nerve deafness, paresis of the soft palate, atrophy and weakness of the sternocleidomastoid and upper trapezium muscles, all on the right side, deviation of the tongue to the right, slurred speech, and dysphagia were observed. The neck was supple. He was able to walk with a support. Mild weakness was present in his right lower extremity. Both legs were spastic. No ataxia or involuntary movements were noted. Deep reflexes were symmetric and normally active. No sensory loss was observed. No meningeal signs were present. Pertinent laboratory findings included moderate anemia (Hb 8.8 g/dl), LDH 2,631 U/l, CRP 7.4 mg/dl. The CSF was under an increased pressure (OP 260 mmH2O) containing 2 lymphocytes/ml, 43 mg/dl of protein, and 49 mg/dl of glucose. Radiologic examinations revealed a destructive change in the sacrum, lytic lesions in the seventh thoracic spine and in the clivus.(ABSTRACT TRUNCATED AT 400 WORDS)

Some patients of dermatomyositis (DM) with interstitial pneumonia (IP) have common clinical features. Clinical features of these patients are acute onset, very poor prognosis and that patients have fever, arthritis, typical skin rash, mild myositis and show low ratio of CPK/LDH, low incidence of antinuclear antibody (ANA) appearance, low inflammatory signs. We experienced two cases of this category of DM with IP and examined immunological aspects. Case 1. A 52-year-old woman was admitted in June 1, 1990 with a one-month history of arthralgia and a ten-days history of fever, skin rash, myalgia and dyspnea on exertion. On examination she had Gottron's papules on her fingers, erythema on back, bilateral elbows and legs, proximal muscle weakness and arthritis. Fine crackles were audible in the lower lung fields. Laboratory data included CPK 200 IU/l, ALD 3.2 IU/l, LDH 805 IU/l. Analysis of bronchoalveolar lavage fluid (BALF) revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid (CS), pulse CS, cyclosporin A. Inspite of these therapies, she died of progressive respiratory insufficiency in July 10, 1990. Case 2. A 23-year-old woman was admitted in April 1, 1991, with a two-month history of arthralgia and a one-month history of fever, skin rash, stomatitis, alopecia. On examination she had Gottron's papules on her fingers, erythema on malar, bilateral elbows and legs, arthritis and stomatitis. Laboratory data included CPK 97 IU/l, ALD 8.5 IU/l, LDH 779 IU/l. She began experiencing dry cough and dyspnea on exertion in May 1991. Analysis of BALF revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid(CS), pulse CS, pulse cyclophosphamide.(ABSTRACT TRUNCATED AT 250 WORDS)

A 41-year-old woman had radical mastectomy for breast cancer with metastasis of axial lymph nodes three years previously. In February 1990, she noticed swelling of lymph nodes in right suparclavicular region. A lymph node biopsy revealed cancer cells. Immediately, radiation therapy was performed. However, in August serum levels of CA 15-3 and LDH were markedly elevated. Two months later the patient complained of severe headache, dysarthria, shoulder pain and anorexia. Neurological examination revealed stiff neck, weakness of bilateral facial muscles, deviation of tongue to the left and no sensory disturbance. A CSF sample by lumbar puncture showed 26/mm3 in cell counts, 204 mg/dl of protein and 11 mg/dl of glucose. In addition, CSF cytology revealed malignant cells four to five times as large as lymphocytes. Immediately, and intrathecal administration of methotrexate (MTX) was started. However, one week later she developed complete paraplegia with sensory disturbance below the L1 levels and an incontinentia urine. CSF examination performed again, and showed 97/mm3 in cell counts, 792 mg/dl of protein and 91 mg/dl of glucose. On October 10, a CT scan of the head showed contrast enhancement along cerebellar folia and narrowing of quadrigeminal cistern. On November 31, sagittal T1W1 with Gadolinium revealed an enhancing stripes along the spinal cord at the Th10 to L4 levels. This finding was suggested to be meningeal carcinomatosis. On December 8, she died. At autopsy, brownish hemorrhagic mass was noticed in the bilateral cerebellar tonsils, and severe downward displacement of the tonsils.(ABSTRACT TRUNCATED AT 250 WORDS)

Rare case of hemolysis following an implantation of the biological mitral valve is presented. In 1985, biological mitral valve of Ionescu-Shiley type was implanted to a 45-year female patient for post-rheumatic mitral defect. Patient was in the III NYHA class before surgery. Her health status improved after operation. Several echocardiographic examinations have shown normal functioning of the implanted valve (normal gradient across the valve, no retrograde wave). Upper respiratory infection with subsequent progressive weakness, anemia, yellow skin, and heart failure occurred in 1991. Echocardiography has shown significant increase (twice) in the gradient across the valve (max 26, mean--14 mm Hg) and retrograde wave of the II degree as well as mitral insufficiency of the II degree. Laboratory tests have shown marked anemia with reticulosis, increase in blood bilirubin, increase in LDH activity (by about ten times), and a decrease in haptoglobins. Mitral valve dysfunction with hemolysis has been diagnosed. Patient was reoperated. Intraoperatively, incompletely healed valvular ring, and lesions to the leaves such as: fibrosis, thickening and partial deficits. Biological mitral valve was replaced with Corin-Carbotest artificial valve. Postoperative course was uncomplicated.

We report a case of dermatomyositis (DM) in a 15-year-old female with toxoplasmosis after ingestion of raw bovine liver. Facial erythema and cervical lymphadenopathy preceded myalgia and muscle weakness of the extremities. The diagnostic criteria of DM was fulfilled because of symmetrical and proximal dominant muscle weakness, elevation of myogenic enzyme (CPK, GOT, LDH, myoglobin, aldorase), myogenic pattern of electromyogram, skeletal muscle biopsy showing interstitial myositis with mild destruction of muscle fiber, and facial erythema. Immunological findings showed IgG anti-toxoplasma antibody to be 1340 IU/ml and IgM to be 7.0 (Cut off index 0.7), suggesting acute toxoplasmosis. Treatment with prednisolone for DM and acetylspiramycin for toxoplasmosis was successful. Toxoplasmosis should be considered as a possibility in patients with myositis.
