Hepatic Glucagonoma in a Post-bariatric Female Patient: A Case Report.

Glucagonomas, neuroendocrine tumors originating from the pancreas marked by excessive glucagon secretion, present a diagnostic challenge due to their rarity and diverse symptomatology. In this report, we present a 47-year-old female with a history of bariatric surgery, diabetes mellitus, and deep vein thrombosis who exhibited weight loss, anemia, migratory necrolytic erythema on the lower limbs and groin, and fecal incontinence. Imaging revealed liver secondary lesions without an identifiable primary tumor. After undergoing surgery, a pathologic examination of the excised tissue confirmed that the lesions were a glucagonoma. This case underscores the imperative of how common side effects of bariatric surgery could mask symptoms, delaying the diagnosis of glucagonomas.

Effects of cadmium and zinc on the quality of quail's eggs.

We report the effects of cadmium (Cd) and zinc (Zn) on the quality of Japanese quail's eggs. For this study, 60 birds were divided into 3 groups of 20 subjects each. The animals in group 1 received 4 mg Zn/d, whereas those in group 2 were given a combination of 4 mg Zn/d and 0.12 mg Cd/d. The quails in group 3 were not given any supplements, acting as controls. The distribution of Cd and Zn in the eggs, the eggs' mass, and the strength and thickness of the shells were determined after 35 and 58 d of supplementation. Zinc showed a positive effect on the mass of eggs and accumulated mainly in the egg white. The content of Cd was significantly lower in the egg yolk of birds in group 1 (p<0.001), whereas those in group 2 had decreased eggshell thickness and strength in comparison to groups 1 and 3 (p<0.001). These results suggest that the adverse effects of Cd on the quality parameters of eggs from commercially important bird species can be, at least in part, counteracted by Zn supplementation.

[Primary amebic meningoencephalitis: 1st case observed in Madagascar]. / Méningo-encéphalite primitive à amibes libres: 1er cas observé à Madagascar.

The primary amebic meningoencephalitis is an acute suppurative infection that involves both the brain and the meninges. It is caused by Naegleria fowleri and is a very rare and fulminating condition, so far nearly always fatal. We report the first case in the area of Southern part of Indian Ocean that occured in a 7-year old French boy living in Madagascar. It is assumed that the disease was contracted by swimming in warm fresh water in a lake of the Madagascar east coast. Clinical signs began 10-12 days after exposure, associating headache, vomiting and pyrexia (39-40 degrees C). Upon admission in a Madagascar hospital, the patient was started on antibiotics, that did not control the disease and soon presented with a loss of consciousness and a delirium. He was transferred to Reunion island (Centre Hospitalier Départemental Félix-Guyon), where the diagnosis of primary amebic meningoencephalitis was confirmed. Therefore, he was started on high-dose of intraspinal amphotericin B, IV amphotericin B lipid complex and tetracycline. He developed myocarditis, diabetes insipidus, deep coma and subsequently died a week later. The diagnosis of amebic meningoencephalitis was based on: -- the cerebrospinal fluid examination that confirmed the diagnosis of purulent meningitis: 420 leucocytes (76% polynuclears, 14% lymphocytes), 90 red blood cells, and showed 50 ameboid trophozoites per 100 leucocytes, approximately 20 microm in size. -- the flagellate transformation test in distilled water showed two anterior flagellas that confirmed the genus Naegleria.

[The effect of supermethrin, an insecticide, on health status indicators in sheep during subchronic poisoning]. / Vplyv insekticídu supermetrín na niektoré ukazovatele zdravotného stavu oviec v podmienkach subchronickej intoxikácie.

The effect of supermethrin on the overall health with respect to weight gains, diet intake, triad values (body temperature, pulse rate and breathing rate) and potential intoxication signs was investigated in sheep of the Slovak Mertino breed (age of 8 months, males and females) during 6-week feeding of the insecticide supermethrin (Research Institute of Chemical Technology, Bratislava). This insecticide supermethrin contains a cyanide group in its molecule and can be included in the group of type II pyrethroids. It is an analog of cypermethrin and it has a different proportion of cis- and trans-isomers. Supermethrin mixed with molasses feed M was administered daily at a dose of 50 mg/kg (about 1/70 of LD50) to five sheep of experimental group I, at a dose of 200 mg/kg (about 1/15 of LD50) to five sheep of experimental group II, and the dose increased from 200 mg to 300 mg/kg l.w. (about 1/20 of LD50) since the fourth week of trial. The main signs of its toxic action involved depressive effects on weight gains (Fig. 4) Over the whole period of trial, the live weight rose by 5.44 +/- 1.94 kg in control group, by 2.66 +/- 1.48 kg in experimental group I, which equates a significant decrease by 51.10% and only 0.34 +/- 0.95 kg in experimental group II, which equates a decrease in weight gains by up to 93.75% against the control. We do not believe that the growth depression can be related to diet intake. There were no larger differences in feed intake between the experimental groups and the control. The growth depression was caused by incessant diarrhea. The patho-morphological examination did not reveal hyperemia and/or intestinal inflammation, the histological examination did not show any lesions of epithelium in the intestinal mucosa. An increase in supermethrin dose from 200 to 300 mg/kg l.w. resulted in signs coming from the CNS. Hypersensibility manifested by moderate unrest, head and neck shaking after auditory, and especially after touch stimuli was observed. This tremor was increasing to became spontaneous 3-4 days before trial termination. The above findings clearly suggest that supermethrin administration at lower doses has harmful effects primarily on the digestive tract, but at higher doses these effects are more intensive accompanied by the effects on the CNS. No negative effects on pulse rate (Fig. 1), breathing rate (Fig. 2) and internal body temperature (Fig. 3) were recorded.

[The effect of bentazone TP, an herbicide, on hematologic indicators in sheep during acute and subchronic poisoning]. / Vplyv herbicídu bentazón TP na hematologické ukazovatele u oviec v podmienkach akútnej a subchronickej intoxikácie.

Hematological changes at poisoning with the bentazone herbicide manufactured by the Research Institute of Chemical Technology in Bratislava were investigated in sheep of the Slovak Merino breed. Acute intoxication in seven head of sheep was induced by a single application of bentazone with cannula at a sublethal dose of 1,450 mg/kg live weight. Bentazone was diluted with sunflower oil at a ratio 1:5. Subchronic intoxication was induced by an administration of bentazone in feed to the sheep for 84 days: a dose of 175 mg/kg live weight (1/10 of LD50) for the first experimental group (six head), and a dose of 97.5 mg/kg live weight (1/12 of LD50) for the second experimental group (six head). The control group did not receive any dietary bentazone. Acute intoxication with herbicide did not cause any statistically significant changes in hemoglobin, erythrocyte and leucocyte counts in the sheep within 120 hours after application. In comparison with the physiological standard, a slight increase in the percentage of neutrophils and a decrease in the lymphocyte percentage were observed. The values of eosinophils, basophils and monocytes remained unchanged. Observation of subchronic intoxication did not reveal any significant negative effect of the two doses of the herbicide within 84 days on the hematological parameters. Our experiments demonstrate that bentazone does not negatively influence blood formation.
