A 33-year-old man with Refsum disease exhibited clinical features of night blindness, dysequilibrium, hearing loss, itchy dry skin, symmetrical polyneuropathy, distal muscle weakness, pes cavus, and hammer toe. His total serum protein was increased, nerve conduction velocities were slow, and serum phytanic acid levels were high. Dietary restriction of phytol resulted in a decrease in serum phytanic acid without any visual and autitory changes; however, coordination, skin lesions, and nerve conduction velocities definitely improved.

On a thoroughbred stud four foals were born with greatly enlarged thyroids and leg weakness. Two foals died within 18 hours of birth, the others subsequently recovered. An enlarged thyroid was also evident in one of the resident mares. The thyroids from the dead foals were hyperplastic. Feed analyses showed that the mares had an iodine intake of about 83 mg daily, 8-8 ppm of the dietary dry matter, due almost entirely to the high iodine content of a proprietary compound horse nut which had been fed at the daily rate of 12 lb per head. It was concluded from the histology of the thyroids, the high intake of iodine, the lack of response to treatment with potassium iodide and the elevated levels of serum protein bound iodine that the condition of the foals on the stud was caused by an excess of iodine fed to the mares during pregnancy.

A rare form of plasma cell dyscrasia characterized by associated polyneuropathy, organomegaly, endocrinopathy, M protein and skin changes has been termed the POEMS syndrome. The pathophysiology is unknown; plasma cell dyscrasia is essential; secondary manifestations are unexplained. We report a 67-year-old man with a 7-month history of progressive weakness and numbness of the legs. Clinical examination revealed sensorimotor polyneuropathy, predominantly affecting the lower extremities, hepatomegaly, and skin haemangiomas. Additional investigations disclosed IgG-lambda monoclonal serum protein, endocrine abnormalities, elevated cerebrospinal fluid protein level and an osteoblastic lesion of the lumbar vertebra. Biopsy of the osteosclerotic vertebra showed a marked lymphoplasmocytic infiltrate. MRI of the liver disclosed two haemangiomas; this association has not been reported previously.

A 20-year-old man with severe physical weakness (from which he soon recovered spontaneously) was found to have hypoproteinaemia and lymphocytopenia (768/microliters). Ten years later, after having been free of symptoms in the meantime, oedema, ascites and abdominal pain occurred, associated with loss of physical capacity. Enteric loss of protein (alpha 1-antitrypsin clearance increased about thirtyfold) with a total serum protein concentration of only 3.7 g/dl, as well as histological evidence of lymphangiectasia of the small and large intestines provided the diagnosis of primary intestinal lymphangiectasia. In the course of the disease cholelithiasis and (after treatment with tranexamic acid) thrombosis of the axillary vein occurred. No treatment has been of any avail and the patient has been unable to work for three years.

Advanced emphysema with bronchitis is associated with significant weight loss and malnutrition, the true cause of which has not been clearly identified. The purpose of this exploratory study was to compare plasma amino acids and related compounds and catecholamines in a group of patients with advanced end-stage emphysema with a control group of similar age and sex in an effort to further understand this malnourished state. Fasting blood samples were obtained by venipuncture after a rest period. Plasma amino acid levels were determined by ion exchange high pressure liquid chromatography with fluorometric detection. Plasma catecholamines were determined by radioenzymatic analysis. Anthropometric measurements, the usually accepted biochemical markers of nutrition, dietary analysis, pulmonary function tests, and a historical analysis of the state of health including drug use and smoking history in each subject were analyzed. Ages and heights were comparable, whereas weights were significantly decreased in the patients with emphysema. Total serum protein and serum albumin values were significantly lower in the patient group. Significant respiratory muscle weakness was indicated by reduced negative inspiratory force in these end-stage patients, contrasting with well-preserved muscle strength usually found in obstructive lung disease. The dietary caloric intake of the patients was comparable to that of the control subjects. We conclude that the fine balance of the amino acid pool in patients with bronchitis and emphysema is well preserved, except for significant elevations of aspartic acid, glutamine, and cystine, and a decreased level of leucine. In addition, norepinephrine levels were significantly increased. Weight loss in patients with emphysema and bronchitis is likely due to increased energy demands related to hypermetabolism.

To clarify the clinical features of fatal cases of active pulmonary tuberculosis, 36 patients with sputum positive for tubercle bacilli on admission were examined retrospectively. They were divided into two groups, those who died of tuberculosis (Group I), and those who died of non-tuberculous diseases (Group II). The mean age of all the patients was 74.8 years, and the male: female ratio was 7 : 3. In Group I (n = 26), the direct causes of death were respiratory failure (35%), general weakness (27%) and acute progression of tuberculosis (31%), and in Group II (n = 10), about half of the patients died of neoplasms. In addition, a control group (Group III) (n = 27) of patients matched for age and sex with Group I, was examined. They were tuberculous patients who had improved and were subsequently discharged after chemotherapy. Compared with Group III, more patients in Group I showed poor oral feeding and had been bedridden on admission. Their nutritional status was significantly poorer, based on determination of total serum protein, albumin, total serum cholesterol, and hemoglobin. With respect to cell-mediated immunity, Group I patients showed significantly lower peripheral lymphocyte counts and a reduced PPD skin reaction. However, the disease was more serious in Group I than in the control. It was suggested that patients subsequently died of active pulmonary tuberculosis showed not only serious illness, but also malnutrition and depressed cell-mediated immunity.

Four kochia grazing trials were completed over a period of 3 years. Yearling steers were allowed to graze pure stands of irrigated and fertilized kochia (Kochia scoparia) for periods of 14 to 105 days. A total of 116 steers were given kochia as their sole forage. Twenty control steers were allowed to graze native grass pasture, and 20 steers were allowed to graze both native grass and kochia pastures. Steers grazing only kochia lost weight or gained poorly compared with control steers grazing native grass. Steers that grazed both kochia and native grass had intermediate rates of gain. Signs of toxicosis were observed only in steers grazing kochia alone. Considerable variability in the degree of toxicosis was observed from one year to another. Morbidity in the steers grazing only kochia varied from 0% (Trial 4) to 28% (Trial 1), and mortality varied from 0% (Trials 3 and 4) to 10% (Trial 2). The most common signs observed in clinically affected steers were depression, dehydration, weight loss, muscular weakness, photosensitization, ocular discharge, and crusty muzzle. In all 4 trials, significant elevations in serum glutamic oxaloacetic transaminase (GOT) and serum gamma glutamyl transpeptidase (GGT) were observed in steers grazing kochia. In 3 of the 4 trials, significant elevations in serum bilirubin, serum calcium, and serum protein were also observed in kochia-fed steers. Necropsies were performed on 6 of 9 steers that died or were euthanized. The primary pathologic findings were severe chronic nephrosis (5 steers) and degenerative hepatopathy (5 steers).(ABSTRACT TRUNCATED AT 250 WORDS)

The following report is a case of multifocal demyelinating motor neuropathy (MMN) presenting as a gradual development of asymmetric motor weakness without sensory involvement. Electrophysiological studies showed mainly a conduction block with normal or slightly slow nerve conduction velocity. Cerebrospinal fluid (CSF) protein and serum protein electrophoresis were normal, but serum IgM anti-GM1 ganglioside antibody was elevated. The patient had a poor response to steroid, plasmapheresis and chemotherapy with cyclophosphamide, but significant improvement was noted after intravenous immunoglobulin (IVIG) infusion. MMN is a potentially treatable condition which clinically mimics a motor neuron disease; if treatment with steroid, plasmapheresis and cyclophosphamide have failed, IVIG may be effective.

A 56-year-old man gradually developed paresthesia and muscular weakness of the left hand and feet for two years. On admission, neurological examination showed predominantly sensory polyneuropathy. Electrophysiological study and sural nerve biopsy demonstrated segmental demyelination, but any underlying congenital, toxic, metabolic or neoplastic cause was failed to reveal. The serum IgM level was 576 mg/dl, while IgG and IgA were normal. An immunoblot analysis and ELISA showed serum IgM antibody that reacted with human MAG. Serum IgM M-protein, however, was detectable not by conventional serum protein electrophoresis and immunoelectrophoresis, but by immunofixation. Anti-MAG antibodies should be evaluated in the patients with slowly progressive demyelinating polyneuropathy of unknown etiology, even if no serum M-protein is detected by conventional methods. Serum M-protein may play a role of pathogenesis of demyelination, and immunofixation method could be beneficial to detect small amount of M-protein.

Clinical, haematological and pathological studies were undertaken in Jordan in a stud of 103 racing horses clinically suffering from babesiosis and apparently healthy animals. Out of 47 horses which participated in strenuous exercise, three mares showed sudden onset of immobility and reluctance to move and two mares died. Clinical examination revealed that these five horses (group 1) had fever, anorexia, weakness and severe icterus and, in two mares, haemoglobinuria. Haematological examination revealed that all five horses were heavily parasitized with Babesia equi. This was also found in four horses (group 2) with no evidence of clinical babesiosis. In group 3 (94 horses), neither clinical signs nor B. equi were observed in the blood. The horses in group 1 and 2 recovered after treatment with imidocarb. When the mean values of white blood cell count, red blood cell count, haemoglobin and packed cell volume in group 1 were compared with those for groups 2 and 3, a significant difference was found (P < 0.05). A significant difference was also found when the mean values were compared before and after treatment. Examination of serum total protein, bilirubin and serum enzymes revealed a significant decrease in the mean value of total serum protein (P < 0.05), and a significant increase in the mean values of bilirubin (P < 0.05) in group 1 compared to groups 2 and 3. A significant elevation in the mean value of aspartate aminotransaminase, gamma-glutamyltransferase and creatine phosphokinase and a substantial elevation in the mean value of alkaline phosphatase was also observed in group 1 compared to groups 2 and 3. Postmortem examination of the dead horses showed that the animals had icterus, hepatomegaly and full urinary bladder with deep-red urine. Histopathological examination of the liver showed massive centrilobular degeneration and necrosis. The bile canaliculi and bile ducts were prominent and plugged with dark-brown to canary-coloured bile pigments. The lungs had congestion, oedema, and thrombosis of pulmonary veins. Our results suggest that the horses suffered from B. equal with clinical manifestation following exercise. The clinical, haematological and pathological findings indicate that the animals suffered from haemolytic anaemia which responded to imidocarb therapy.
