[Clinical aspects and therapy of gastrogenic tetany].

The author observed 477 patients with sub- and decompensated stenosis of the pylorus of ulcer etiology; 11 out of them developed a severe complication--chloroprivic tetany which resulted from repeated abundant vomiting in emaciated patients and was followed by an acute total dehydration of the body, decrease of chlorides, oliguria and azotemia. Some problems concerning the prevention and the treatment of this severe complication of peptic ulcer are described.

[Two cases of the diencephalic syndrome were reported with hormonal studies (author's transl)].

Two cases of the diencephalic syndrome were reported with hormonal studies. The first case was initially admitted at her age of 4 years and 10 months old. Progressive visual disturbance and horizontal nystagmus had developed one year prior to the admission. Her weight gain had stopped since 10 months old. Partial removal of the hypothalamic pilocytic astrocytoma and 5,000 rad of lineac radiotherapy brought satisfactory effects on her previous symptoms. She was readmitted, however, at her age of 8 years and 10 monts old because of precocious puberty. Her breast development was in Tanner's grade 2, and her bone maturation was equivalent to one of 11 years old. Hormonal studies showed decreased urine 17-OHCS and 17-KS, elevated serum LH, E1 and E2. The CT scan disclosed some enhanced area in the vicinity of the optic chiasm, which had not changed for the last one year. The second case was admitted at his age of 10 years and 9 months old because of progressive marked emaciation of 6 months' duration. Parinaud's sign was only positive neurological finding. The CT verified enhanced areas in the pineal and chiasm. Cytological study of CSF gave the diagnosis of germinoma. Hormonal studies showed decreased urine 17-OHCS and 17-KS, decreased T3, T4, ACTH, and increased PRL as well as increased HGH. Local lineac irradiation by 5,500 rads was given, during which the enhanced area in CT disappeared and his weight gain started. Increased HGH became normalized but paradoxical response of HGH to GTT remained same.

[Dysperception of body image and dysmorphophobias in mental anorexia. Apropos of 115 cases involving both sexes. I. Altered mechanisms of perception in mental anorexia].

We noted frequency of body-image disturbance (BID) and dismorphophobias (DPP) in 97 girls and 8 boys among 107 girls and 8 boys with Anorexia Nervosa (AN), seen since 1973 and coming up semiologic criterions of Laboucarie and Dally & Sargant. 91,5% of the girls and 7 out of 8 boys presented a BID at one time of their evolution. The other ones did not form a characteristic group. BID prevailed in no-perception of emaciation. No-perception of overweight was exceptional. That of variations of weight was frequent, explaining to need objective elements to measure real volume. BID seems to result from an incapacity to integrate well individually perceived details into a coherent image. Its apparition signals starting of AN, and it is a fundamental criterion of evolutivity. It's not frequent it's extended to body-image disperception of the close people, but it is often associated to an increase of mental representation of ingested feed volume.

[Dysperception of body image and dysmorphophobias in mental anorexia. Apropos of 115 cases involving both sexes. III. Physiopathogenic deductions and introduction of a novel definition of the disease].

Ignoring of emaciation (IE), fear of any weight recovery (Dalpha), and dismorphophobias (DPP) represent the central problem of AN, with different incidence. Fundamental need of being lean expresses, at lesss in girls, distress of personality insufficiently prepared to autonomous adult life, with its responsabilities. Obesity-DPP may correspond to projection upon the body of the obsessing conviction of being inferior, with regard to social and publicitary patterns, and get an active play in starting and management of weight loss. So AN is either an attempt to accomodate this critic situation, trying to incarnate actual female archetype, either, in the more severe cases, a renouncing with an obstinate physical and psychological recession to the state of a protected child. It seems to correspond to an attempt of negation of morbid character of this situation, so that it may be perpetuated and so that feeling of culpability can be decreased in front of familial recrimination. Constancy of these symptoms, and their relation with deep meaning of this illness, justify their introduction into a new definition of AN, diagnosed by association of at less 2 out of 3 major criterious (loss of weight superior to 10% premorbid weight, feed restrictions and Dalpha) and one out of 2 minor criterions (amenorrhea and IE).

The use of custom-designed midfacial and submalar implants in the treatment of facial wasting syndrome.

Facial wasting syndrome is part of a lipodystrophy that occurs as a complication of highly active antiretroviral therapy. The loss of subcutaneous fat in the cheeks and temples results in a hollow-eyed, bony, emaciated appearance that is characteristic of the results of treatment of human immunodeficiency virus. Cessation of therapy results in a rebound in viral load and subsequent morbidity. The appearance of facial wasting syndrome is optimally treated with custom-designed implants that are made using high-resolution computed tomography combined with surgeon input and computer-aided design and manufacturing technology. Twenty-two patients with facial wasting syndrome were treated using either submalar implants (in more moderate cases) or custom-designed implants (in more severe cases). In each patient, the appearance of volumetric soft tissue restoration was successfully achieved, returning a permanent and more healthful appearance to the face.

Corneal perforation in patients with vitamin A deficiency in the United States.

An emaciated alcoholic 52-year-old white woman presented with an old left corneal perforation and bilateral conjunctival and corneal xerosis. The serum vitamin A level was 0 mumol/L. Laboratory and radiologic findings were consistent with the diagnosis of a fat malabsorptive syndrome secondary to chronic alcoholic pancreatitis. Histopathologic evaluation of her enucleated globe revealed conjunctival epidermidalization, corneal perforation with prolapse and loss of intraocular contents, retinal detachment, and massive choroidal hemorrhage. A second patient presented with bilateral conjunctival xerosis, corneal ulcers, and a low serum vitamin A level. Corneal perforation of one ulcer ensued during her hospitalization. Medical investigation revealed hepatic metastases of an unknown primary source. Causes of vitamin A deficiency and its ocular complications as well as medical and surgical management options are discussed.

Food refusal and insanity: sitophobia and anorexia nervosa in Victorian asylums.

Although anorexia nervosa emerged as a new syndrome in the second half of the 19th century, this clinical picture seemed to be unknown in the psychiatric hospitals or asylums. In asylum medicine, the commonly used concept of sitophobia to designate food refusal in the insane covered a wide variety of mental disturbances and cannot be plainly equated with anorexia nervosa. A major difference is the occurrence of hallucinations and delusions specifically centered around religion and digestion. Most probably, anorectic patients were not treated in asylums, but at home, in the doctor's office, or in general hospitals. This pattern may be partly attributed to the fact that both patients and doctors were focusing on symptoms of self-starvation like emaciation, constipation, and amenorrhea, which were primarily interpreted as referring to somatic diseases. Additionally, wealthy families probably preferred private care in water-cure establishments, sanatoria, and rest homes to the stigmatizing referral of their anorectic daughter to an asylum. Hence, the fact that late 19th-century institutionalized psychiatry was only incidentally confronted with anorexia nervosa may explain its lack of interest in the emerging syndrome.

Blood-letting in anorexia nervosa: a case study.

BACKGROUND: Deliberate blood-letting has been characterized as an alternative to purging behavior in bulimia. METHOD: We describe a female healthcare worker with an 8-year history of restrictive anorexia nervosa, who initially presented with anemia, using blood-letting, cold baths, and starvation to control her mental state. RESULTS: In contrast with the previous cases of bulimia, the aim of blood-letting in this case of anorexia nervosa was to achieve anemia. She compared the psychic correlates of anemia to emaciation, rather than to deliberate self-harm or purging. DISCUSSION: We note that mainstream 19th century psychiatry prescribed "baths, blood-letting and diet" as a treatment of "madness."

Modified surgical procedures in intestinal tuberculosis.

The results of modified surgical procedures in intestinal tuberculosis in 79 patients are presented. Special emphasis is laid on the role of limited ileocaecal resection and ileoplasty. These procedures are safe, quick and easy with preservation of functional portions of the bowel. They are of immense value in emergencies in chronically ill and emaciated patients.

Unexplained acidosis of malnutrition: a study by ion-exchange chromatography/mass spectrometry.

Keto-acidosis is usually associated with uncontrolled diabetes and typically poses few diagnostic problems when presenting as hyperglycaemia, metabolic acidosis and a high anion gap. An emaciated patient suffering from Duchenne Muscular Dystrophy and volume depletion presented with acidosis of unknown origin. Preliminary investigations appeared to rule out lactic acidosis, diabetic keto-acidosis and acidosis due to base loss. We have previously reported a technique utilizing liquid chromatography coupled to mass spectrometry (LC-MS) which can be used to characterize the underlying aetiology of acidosis and applied it to ultrafiltrate derived from a blood sample taken from this patient. The anion profile obtained on the chromatogram showed elevated levels of acetoacetate and hydroxybutyrate but no evidence of lactic acidosis, nor was the profile typical of that seen in 'unexplained' acidosis. We concluded that the patient was suffering from keto-acidosis associated with starvation and dehydration, the biochemical features being obscured by both the patient's chronic malnutrition and minimal muscle mass. A combination of enteral feeding and rehydration led to prompt resolution of the patient's metabolic acidosis.

Etiology of hypercholesterolemia in patients with anorexia nervosa.

OBJECTIVE: Hypercholesterolemia is common in patients with anorexia nervosa (AN) despite emaciation. The objective of this study was to clarify the mechanism of hypercholesterolemia in AN. METHOD: We measured serum lipids in 39 patients with AN and analyzed serum lipid profiles in the 24 patients in comparison with five age-matched controls. RESULTS: Mean serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), ketone bodies, apolipoprotein (apo)-A1, B, C2, C3, E, and cholesterol ester transfer protein (CETP) activity were significantly higher in patients with AN than in controls. No significant difference in serum free fatty acid (FFA) levels was observed between patients with AN and controls. CETP was accelerated in patients with AN with hypercholesterolemia. No correlation was apparent between serum levels of cholesterol and thyroid hormones. CONCLUSION: Serum levels of cholesterol, CETP, and apolipoproteins decreased after weight gain, indicating that cholesterol metabolism is accelerated in patients with AN with normal serum levels of FFA.

Some pathological and biochemical studies on experimental ascaridiasis in chickens.

During studying the pathogenicity of Ascaridia galli for young Ross-Broiler chickens fed with single doses of 100, 200 and 500 infective eggs, it was found that the infected chickens showed variable decreases in body weight gain and increases in the ratio of liver weight relative to body weight when compared with the control. Both decrease and increase was proportionally related with the number of infective eggs given to the chickens. Biochemical analysis of muscle and liver tissue of the previous groups of chickens showed a decrease in both glycogen and protein content and an increase in fat content of muscle and liver of infected chickens when compared with those of normal tissues. The decrease in the glycogen content due to ascaridiasis was mostly apparent in case of 500 egg dose and that of the protein content was noted with the egg doses of 200 and 500. Each of the three egg doses showed a significant increase in the fat content of the muscle and liver of infected chickens when compared with the control. After the sixth week of infection chickens fed with 500 eggs showed emaciation, loss of colour of combs and legs and of brightness of plumage, diarrhoea, drooping wings, ruffled feathers and a gradual loss of strength manifested by leg weakness. At autopsy, the small intestine showed external macroscopic lesions of haemorrhage and congestion. Intestinal obstruction with adult Ascaridia galli was also found in the infected birds.

Molecular analysis of lipid-depleting factor in a colon-26-inoculated cancer cachexia model.

Cachexia in cancer is characterized by progressive emaciation involving depletion of host adipose tissue stores, the molecular mechanism of which remains largely unknown. In this study, we have attempted to clarify the biologic characteristics of lipid-depleting factor in a mouse cachexia model. Utilizing differentiated 3T3-L1 adipocytes, we established an assay method quantifying the lipid-depleting activity in plasma derived from colon-26-inoculated mice and then analyzed the associated molecular mechanism. Injection (s.c.) of a mouse colon adenocarcinoma cell line, colon-26 clone 20, induced cachexia, as evidenced by progressive weight loss. Addition of clone 20-derived cachexigenic, but not clone 5-derived noncachexigenic, plasma to the culture medium of differentiated 3T3-L1 adipocytes reduced the TG content in cultured cells. The ability of the introduced plasma to induce TG loss in 3T3-L1 cells paralleled the body weight changes of tumor-inoculated host mice. Clone 20 plasma, but not clone 5 plasma or recombinant IL-6, elicited lipolytic activity, which induced glycerol release from 3T3-L1 cells. Addition of clone 20 plasma to cultured 3T3-L1 adipocytes reduced TG synthesis from [(14)C]-glucose compared to clone 5 plasma, indicating that the lipid-depleting activity resulting from addition of clone 20 plasma depended not only on induction of lipolysis but also on inhibition of lipogenesis. Addition of clone 20 plasma to cultured 3T3-L1 adipocytes reduced the quantity of mature SREBP-1 in the nucleus of 3T3-L1 cells without affecting PPAR-gamma and C/EBP-alpha. Although TNF-alpha induced apoptosis in 3T3-L1 cells, clone 20 plasma did not. These results suggest that the lipid-depleting factor in clone 20 plasma is different from either IL-6 or TNF-alpha, and that this factor interfered with not only lipolysis but also lipogenesis through SREBP-1 of 3T3-L1 adipocytes.

Acute toxicity study of 1,3,3,5,5-pentaziridino-1-thia-2,4,6-triaza-3,5-diphosp horine-1-oxide (a new antitumor agent with an inorganic ring) in mice, rats and dogs.

In order to study the safety of 1,3,3,5,5-pentaziridino-1-thia-2,4,6-triaza-3,5-diphospho rine-1-oxide (SOAz), a new antitumor agent, acute toxicity studies by intravenous administration were performed in ddY mice, Wistar rats and beagle dogs. The LD50 values in rodents were 325 mg kg-1 for male mice, 450 mg kg-1 for female mice, 100 mg kg-1 for male rats and 82 mg kg-1 for female rats. In dogs, the LD50 values were 12 mg kg-1 for males and 18 mg/kg-1 for females. The dosed animals showed diarrhoea and decreased movement in the three species, and emaciation and loss of body weight in mice and rats. Dogs also showed signs of pneumonia. Histopathological examination revealed bone marrow suppression, atrophy of lymphoid organs and testes, and damage to the digestive tract mucosa in the three species. The main causes of death from single-dose administration were bone marrow aplasia and atrophy of lymphoid tissue in all species, together with gastro-intestinal ulceration in rats and dogs, and infection in mice and dogs.

Blubber development in bottlenose dolphins (Tursiops truncatus).

Blubber, the lipid-rich hypodermis of cetaceans, functions in thermoregulation, buoyancy control, streamlining, metabolic energy storage, and locomotion. This study investigated the development of this specialized hypodermis in bottlenose dolphins (Tursiops truncatus) across an ontogenetic series, including fetuses, neonates, juveniles, subadults, and adults. Blubber samples were collected at the level of the mid-thorax, from robust specimens (n = 25) that stranded along the coasts of North Carolina and Virginia. Blubber was dissected from the carcass and its mass, and the depth and lipid content at the sample site, were measured. Samples were prepared using standard histological methods, viewed by light microscopy, and digital images of blubber captured. Images were analyzed through the depth of the blubber for morphological and structural features including adipocyte size, shape, and numbers, and extracellular, structural fiber densities. From fetus to adult, blubber mass and depth increased proportionally with body mass and length. Blubber lipid content increased dramatically with increasing fetal length. Adult and juvenile blubber had significantly higher blubber lipid content than fetuses, and this increase was reflected in mean adipocyte size, which increased significantly across all robust life history categories. In juvenile, subadult, and adult dolphins, this increase in cell size was not uniform across the depth of the blubber, with the largest increases observed in the middle and deep blubber regions. Through-depth counts of adipocytes were similar in all life history categories. These results suggest that blubber depth is increased during postnatal growth by increasing cell size rather than cell number. In emaciated adults (n = 2), lipid mobilization, as evidenced by a decrease in adipocyte size, was localized to the middle and deep blubber region. Thus, in terms of both lipid accumulation and depletion, the middle and deep blubber appear to be the most metabolically dynamic. The superficial blubber likely serves a structural role important in streamlining the animal. This study demonstrates that blubber is not a homogeneous tissue through its depth, and that it displays life history-dependent changes in its morphology and lipid content.

Familial amyloid polyneuropathy related to transthyretin Gly42 in a Japanese family.

A Japanese family is described in which 6 persons showed familial amyloid polyneuropathy (FAP). Mean ages of onset were 38 for 4 males and 54 for 2 females. Three of the 6 became emaciated and died after 4 to 10 years. In 5, muscular weakness and autonomic dysfunction were the initial symptoms followed by sensory disturbances. Amyloidotic cardiomyopathy was present in 3 of the subjects. Amyloid deposits showed an immunohistological relation to transthyretin (TTR). Analysis of 1 patient's TTR gene revealed a single base change (A----G) that led to amino acid substitution (Glu42----Gly). This base change produced a new restriction site for endonuclease Cfr13 I in exon 2. Polymorphic analysis of the length of the Cfr13 I-restriction fragment confirmed the base change, and made it possible to detect the mutant TTR Gly42 gene in the FAP subjects. Amino acid sequencing analysis showed a variant of TTR Gly42 in 1 patient's serum.

Neurotoxicity of 2-bromopropane and 1-bromopropane, alternative solvents for chlorofluorocarbons.

To clarify the neurotoxicity of 2-bromopropane (2-BP) in comparison with 1-bromopropane (1-BP), 36 Wistar strain male rats were divided into 4 groups of 9 and exposed daily to 100-ppm 2-BP, 1000-ppm 2-BP, 1000-ppm 1-BP, or fresh air for 8 h a day. Exposure to 1000 ppm of 1-BP was discontinued after 5 or 7 weeks' exposure because of the unexpected appearance of incomplete hindlimb paralysis followed by serious emaciation. The other groups were sacrificed at the end of 12 weeks' exposure. Exposure to 1000 ppm of 2-BP resulted in significant decreases in body weight and motor nerve conduction velocity (MCV) and elongation in distal latency (DL). A ball-like enlargement of myelin sheaths was observed. Significant reductions in the number of erythrocytes, platelets, and leukocytes, testicular germ cell loss, and seminiferous atrophy were also observed in this group, but not in 100-ppm 2-BP group. Exposure to 1000 ppm of 1-BP for 5 or 7 weeks caused a significant decrease in body weight and MCV and elongation in DL. Linearly arranged ovoid- or bubble-like debris of the axons and myelin sheaths in the teased tibial nerves and axonal swelling in gracilis nucleus were found in this group. No significant changes in hematological indices or histopathological findings of the testis were found in this group. In conclusion, 2-BP is neurotoxic to the peripheral nerves in addition to its toxic effects on the reproductive and hematopoietic systems at 1000 ppm. No noticeable changes were found in the rats exposed to 100 ppm of 2-BP. 1-BP is a potent neurotoxicant at 1000 ppm for 5 or 7 weeks, while testicular and hematopoietic toxicity was not found.

Hydrocephalus in the Otx2+/- mutant mouse.

Mice with the Otx2+/- mutation often die during the postneonatal period. Before death these animals, generated from TT2 ES cells and crossed with CBA mice, develop a dome-shaped head, weakness of the limbs, kyphosis, lethargy, drowsiness, and emaciation. Autopsy of these mice revealed eminent dilatation of lateral ventricles and a ballooned cerebrum. Histological analysis shows edematous change of the periventricular white matter. These results suggest that Otx2 functions as a head organizer, and a mutation of this gene is a likely cause of hydrocephalus in mammals. Additionally, craniobasal skeletal anomaly in half of the heterozygotes and dwarfism in some of the female heterozygotes are described.
