A 36-year-old man with prolonged confusion developed after psychomotor status was reported. He had no past history of epileptic seizures or psychotic disorders. The status continued for 20 hours, and twilight state and a slight fever lasted for about 10 days. Thereafter gross impairment of memory and disorientation became remarkable, and, in addition, strong psychic and autonomic disturbances developed, such as visual and auditory hallucinations, excessive excitement, disturbance of sleep, polyphagia, polydypsia, polyuria and hyperhidrosis. The CT scan, carotide angiography, CSF examination, and complement fixation tests for viruses were all within normal limits. The EEGs showed a slowing of the background activity, 0.6--0.8 Hz periodic high voltage wave discharges and random spikes in each temporal area. The clinical symptoms and EEG findings gradually improved without remarkable damage.

Clinical observations suggest that overt rhabdomyolysis may occur if severe hypophosphatemia is superimposed upon a pre-existing subclinical myopathy. To examine this possibility, a subclinical muscle cell injury was induced in 23 dogs by feeding them a phosphorus- and calorie-deficient diet until they lost 30% of their original weight. To induce acute, severe hypophosphatemia in the animals after partial starvation, 17 of the dogs were given large quantities of the same phosphorus-deficient diet in conjunction with an oral carbohydrate supplement, which together provided 140 kcal/kg per day. After phosphorus and caloric deprivation, serum phosphorus and creatine phosphokinase (CPK) activity were normal. Total muscle phosphorus content fell from 28.0+/-1.3 to 26.1+/-2.5 mmol/dg fat-free dry solids. Sodium, chloride, and water contents rose. These changes resembled those observed in patients with subclinical alcoholic myopathy. When studied after 3 days of hyperalimentation, the animals not receiving phosphorus showed weakness, tremulousness, and in some cases, seizures. Serum phosphorus fell, the average lowest value was 0.8 mg/dl (P <0.001). CPK activity rose from 66+/-357 to 695+/-1,288 IU/liter (P <0.001). Muscle phosphorus content fell further to 21.1+/-7.7 mmol/dg fat-free dry solids (P <0.001). Muscle Na and Cl contents became higher (P <0.01). Sections of gracilis muscle showed frank rhabdomyolysis.6 of the 23 phosphorus- and calorie-deprived dogs were also given 140 kal/kg per day but in addition, each received 147 mmol of elemental phosphorus. These dogs consumed their diet avidly and displayed no symptoms. They did not become hypophosphatemic, their CPK remained normal, and derangements of cellular Na, Cl, and H(2)O were rapidly corrected. The gracilis muscle appeared normal histologically in these animals. These data suggest that a subclinical myopathy may set the stage for rhabdomyolysis if acute, severe hypophosphatemia is superimposed. Neither acute hypophosphatemia nor rhabdomyolysis occur if abundant phosphorus is provided during hyperalimentation.

Intestinal lymphangiectasia (IL) may vary widely in its manifestations and severity. Fifteen children seen between 1960 and 1974 with histologically proven IL are analyzed by clinical, laboratory, radiologic, and histologic criteria. Remissions occurred in most patients and none died. Exacerbations occurred in five children. Diarrhea was present in 14 patients and in 13 appeared before the age of 3 years. Vomiting occurred in nine patients and growth retardation in seven. Four children had associated peripheral lymphedema and two of these had a family history of lymphedema, both had affected fathers and one had affected siblings and paternal cousins. Seven had hypoproteinemic edema, and of these, four suffered from hypocalcemic seizures. Chylous effusions were present in five. Hypoproteinemia was present in 12 although five had no hypoalbuminemic edema. Six had lymphopenia which was related to the severity of the disease and was the last abnormality to disappear after clinical remission. Lymphopenia may first appear years after the protein loss begins. Upper gastrointestinal tract series were performed in 13 children and had diagnostic supportive value in seven. Six children had two or more small-intestinal biopsies done. They all showed great variation from one examination to the other, ranging from a normal appearance to severe changes. Lymphatic block may occur at different sites-in the lamina propria only, generalized (lamina propria, submucosa, serosa, and mesentery), or conversely in the mesentery alone with minimal changes in the lamina propria. In three patients intravenous hyperalimentation was necessary. Specific treatment with a high-protein, low-fat diet with added medium-chain triglyceride (MCT) is valuable. Surgical resection was of benefit in one patient, and anastomosis of mesenteric to para-aortic lymph nodes in another.

Serious complications may arise from improper central venous catheter placement. In this case report, seizures occurred as a result of inadvertent arterial administration of parenteral hyperalimentation. There is a need for radiographic confirmation of central venous catheter position by qualified personnel before catheter use.

Medium-chain triglycerides (MCT) are an important component of an enteral ketogenic diet for seizure control. Previously, it was difficult to maintain ketosis when parenteral (iv) nutrition therapy was necessary. The use of iv MCT in a 5-year-old girl with Lennox-Gastaut syndrome who had diarrhea and dehydration is reported. Conventional 20% iv fat emulsion (long-chain triglycerides, LCT) and dextrose free hyperalimentation (HAL) in a 4:1 ketogenic ratio did not maintain adequate ketosis during bowel rest. Compassionate use of iv MCT (Clintec Nutrition) infused as a 70:30 MCT/LCT ratio plus HAL maintained moderate ketosis. Seizures were well controlled during the iv MCT regimen, which allowed normal daily functioning. Complications included abnormal liver function tests and severe iron deficiency anemia of unknown etiology. Serum triglyceride and cholesterol levels increased to 1717 mg/dl and 614 mg/dl, respectively, but decreased with a reduction of lipid infusion and use of an antihyperlipemic drug. Nutritional status was maintained. In this case, iv MCT proved to be a relatively safe and effective short-term method of continuing parenteral nutrition while maintaining ketosis for seizure control.

Acromegaly was diagnosed in 14 middle-aged to old cats of mixed breeding. Thirteen (93%) of the cats were male and one was female. The earliest clinical signs in the 14 cats included polyuria, polydipsia, polyphagia, all of which were associated with untreated diabetes mellitus. All developed severe insulin resistance within a few months; peak insulin dosages required to control severe hyperglycemia ranged from 20 to 130 U per day. Other clinical findings weeks to months after diagnosis included enlargement of one or more organs (e.g., liver, heart, kidneys, and tongue) (n = 14), cardiomyopathy (n = 13), increase in body size and weight gain (n = 8), nephropathy associated with azotemia and clinical signs of renal failure (n = 7), degenerative arthropathy (n = 6), and central nervous system signs (i.e., circling and seizures) caused by enlargement of the pituitary tumor (n = 2). The diagnosis of acromegaly was confirmed by demonstration of extremely high basal serum growth hormone concentrations (22 to 131 micrograms/l) in all cats. Computerized tomography disclosed a mass in the region of the pituitary gland and hypothalamus in five of the six cats in which it was performed. Two cats were treated by cobalt radiotherapy followed by administration of a somatostatin analogue (octreotide), whereas two cats were treated with octreotide alone. Treatment had little to no effect in decreasing serum GH concentrations in any of the cats. Eleven of the 14 cats were euthanized or died four to 42 months (median survival time, 20.5 months) after the onset of acromegaly because of renal failure (n = 2), congestive heart failure (n = 1), concomitant renal failure and congestive heart failure (n = 3), progressive neurologic signs (n = 2), persistent anorexia and lethargy of unknown cause (n = 1), the owner's unwillingness to treat the diabetes mellitus (n = 1), or unknown causes (n = 1). Results of necropsy examination in ten cats revealed a large pituitary acidophil adenoma (n = 10), marked left ventricular and septal hypertrophy (n = 7), dilated cardiomyopathy (n = 1), arthropathy affecting the shoulder, elbow, or stifle (n = 5), and glomerulopathy characterized by expansion of the mesangial matrix and variable periglomerular fibrosis (n = 10).

An acute limbic-cerebellar syndrome was seen in six industrial workers who inhaled trimethyltin (TMT). Clinical features included hearing loss, disorientation, confabulation, amnesia, aggressiveness, hyperphagia, disturbed sexual behavior, complex partial and tonic-clonic seizures, nystagmus, ataxia, and mild sensory neuropathy. Severity paralleled maximal urinary organotin levels. One patient died and two remained seriously disabled.

Hyposexuality is a common problem in stroke patients. Some stroke patients, however, may present with hypersexuality. We report three stroke patients who demonstrated hypersexuality and deviant sexual behavior after stroke. Abnormal sexual behavior was noted by members of the stroke rehabilitation team while the patients were in hospital. Details of pre- and poststroke sexual activity were obtained from patients and their spouses. All three patients had temporal lobe lesions on computerized tomography, and all had a history of poststroke seizure activity. The 53-year-old man reported poststroke increase in libido and coital frequency with a tendency towards priapism. The two women (47 and 55 years old) exhibited deviant sexual behavior, mood changes, and hyperphagia. The exact cause of these behavior changes is unknown but they may be related to temporal lobe involvement. Hypersexuality has previously been reported in animals and in patients with temporal lobe seizures.

Previous reports have described a syndrome of paresthesias, weakness, seizures and hypophosphatemia in patients and animals receiving intravenous hyperalimentation. In this report we describe a group of five patients who developed this syndrome while on oral caloric intake and three patients who received only modest amounts of hyperalimentation therapy. As an experimental corollary, studies were performed in starved and normal dogs with calories infused via an intragastric catheter. The serum inorganic phosphorus (Pi) fell slightly in normal animals from 4.8-2.5 mg. %. In the starved dogs with diarrhea or vomiting the Pi fell gradually from 4.8-1.6. In starved dogs without gastrointestinal symptoms the Pi fell precipitously from 3.7-1.4 mg % on the first day of infusion and remained at that level. Approximately 50% of the starved animals developed the neurological syndrome; none of the normal animals had neurological symptoms.

A young man developed pathological thirst and hyperdipsia, hyperphagia, disordered temperature regulation, a lowered threshold for aggressive behavior, apathy, impaired memory, and seizures following encephalitis. He had marked hyponatremia. Bouts of water drinking produced water intoxication and precipitated status epilepticus. Studies of water handling with measurements of plasma osmolality and arginine vasopressin (AVP) revealed a very low thirst threshold (below 242 mOsm/kg) with resetting of the osmostat to a new level (255 mOsm/kg) but normal control of plasma osmolality at that level with adequate AVP release.
