Two previously healthy infants, a boy of 10 weeks and a girl of 4 months presented with apathy and muscle weakness. A third previously healthy child, a girl of 6 weeks old was admitted with respiratory insufficiency. None of the three had had a bowel movement for a number of days. After extensive investigations which revealed few abnormalities Clostridium botulinum toxin was obtained in serum from all three children. Type-B-toxin was shown in the faeces of the older girl and boy; both recovered quickly. The other girl had type-A toxin; she died. Two of the three children were given honey to comfort them. Infantile botulism must be considered in every infant with symptoms of constipation and hypotonia. The diagnosis can quickly be confirmed by electromyography with repetitive 50-Hz-stimulation. Honey is a well-known source of the C. botulinum spore and should not be given to children under the age of 12 months. These three children are the first cases to be described in the Netherlands.

During World War II, 36 conscientious objectors participated in a study of human starvation conducted by Ancel Keys and his colleagues at the University of Minnesota. The Minnesota Starvation Experiment, as it was later known, was a grueling study meant to gain insight into the physical and psychologic effects of semistarvation and the problem of refeeding civilians who had been starved during the war. During the experiment, the participants were subjected to semistarvation in which most lost >25% of their weight, and many experienced anemia, fatigue, apathy, extreme weakness, irritability, neurological deficits, and lower extremity edema. In 2003-2004, 18 of the original 36 participants were still alive and were interviewed. Many came from the Historic Peace Churches (Mennonite, Brethren, and Quaker), and all expressed strong convictions about nonviolence and wanting to make a meaningful contribution during the war. Despite ethical issues about subjecting healthy humans to starvation, the men interviewed were unanimous in saying that they would do it all over again, even after knowing the suffering that they had experienced. After the experiment ended, many of the participants went on to rebuilding war-torn Europe, working in the ministries, diplomatic careers, and other activities related to nonviolence.

Five days after birth of a viable Fell pony filly, yellow watery diarrhoea appeared without any signs of systemic disease. Four days later the diarrhoea ceased. On 11th day, the animal showed apathy, and a few days later, the foal was very lethargic, suffered from muscular weakness and severe watery diarrhoea that reappeared. The illness did not respond to therapy. At the age of 21 days the filly spontaneously died under symptoms of intestinal colic and pneumonia. Haematological examinations revealed lower numbers of erythrocytes as well as non-selective lymphopenia. Phagocytic activity was slightly increased, lymphocyte activity was inhibited. Histopathology showed severe alteration of the lymphatic organs. T and B lymphocytes and antigen-presenting macrophages were not arranged in characteristic areas, and the quantity of these cells was lower than would be expected. Histopathological changes in lymphatic organs resembled those described in the literature as severe combined immunodeficiency.

Vitamin B(12) deficiency in infants often produces haematological and neurological deficits, including macrocytic anaemia, neurodevelopmental delay or regression, irritability, weakness, hypotonia, ataxia, apathy, tremor, and seizures. The diagnosis of vitamin B(12) deficiency can be difficult when the typical macrocytic anaemia is absent. We report the case of a 10-month-old female diagnosed with West syndrome associated with vitamin B(12) deficiency but without macrocytic anaemia caused by nutritional inadequacy in the mother. The patient's motor skills and cognitive development were normal until she was 9 months old, when she began to exhibit a series of sudden flexions of the head, trunk, arms, and legs. She was exclusively breast-fed and had received no vitamin supplementation. Results of electroencephalography (EEG) indicated modified hypsarrhythmia and the patient was diagnosed as having West syndrome. Synthetic adrenocorticotropic hormone was administered and although her spasms had resolved, the patient remained apathic and could not sit without assistance. EEG results indicated generalized slow activity. After she was diagnosed as having vitamin B(12) deficiency, parenteral treatment with vitamin B(12) was initiated. Her symptoms resolved and EEG was completely normal. When she was 20 months old she exhibited an age-appropriate developmental and neurological profile. To our knowledge, this is the first report of West syndrome as a presenting symptom of vitamin B(12) deficiency.

The performance of clinical signs as a diagnostic test for the detection of BTV-8 outbreaks during the 2006-epidemic in The Netherlands was evaluated by constructing and analysing receiver operating characteristic (ROC) curves. The area under the ROC curve of the BT-associated clinical signs in cattle was 0.77. An optimal efficient test (maximising both sensitivity and specificity) in cattle herds combined a sensitivity (Se) of 67% with a specificity (Sp) of 72%, comprising the following clinical signs: ulcerations and/or erosions of oral mucosa or erosions of lips/crusts in or around nostrils or oedema of the nose or hyperaemic/purple coloration of tongue, tongue protrusion or coronitis or apathy/tiredness or muscle necrosis, stiffness of limbs or loathing or refusal to move, prostration or torticollis or anoestrus. The area under the ROC curve of the BT-associated clinical signs in sheep was 0.81. The optimal efficient test in sheep flocks combined a Se of 76% with a Sp of 72%, comprising the following clinical signs: ulcerations of oral mucosa or serous nasal discharge or erosions/ulceration of tongue mucosa or hypersensitivity of the skin or muscle necrosis, stiffness of limbs or coronitis or grinding of teeth or salivation or weakness/paresis.

A 4-month-old female Holstein Friesian calf was referred to the Veterinary Teaching Hospital, University of Berne, Switzerland for evaluation of ataxia, weakness, apathy and stunted growth. Clinical examination revealed generalized ataxia, propioceptive deficits, decreased menace response and sensibility. Postmortem examination did not reveal macroscopic changes of major organs. Histologically, the brain and the spinal cord lesions were characterized by polymicrocavitation, preferentially affecting the white matter fibers at the junction of grey and white matter and by the presence of Alzheimer type II cells. The liver revealed lesions consistent with a congenital portosystemic shunt, characterized by increased numbers of arteriolar profiles and hypoplasia to absence of portal veins. The pathological investigations along with the animal history and clinical signs indicated a hepatic encephalomyelopathy due to a congenital portosystemic shunt.

Scurvy is a thousand-year-old stereotypical disease characterized by apathy, weakness, easy bruising with tiny or large skin hemorrhages, friable bleeding gums, and swollen legs. Untreated patients may die. In the last five centuries sailors and some ships' doctors used oranges and lemons to cure and prevent scurvy, yet university-trained European physicians with no experience of either the disease or its cure by citrus fruits persisted in reviews of the extensive but conflicting literature. In the 20(th) century scurvy was shown to be due to a deficiency of the essential food factor ascorbic acid. This vitamin C was synthesized, and in adequate quantities it completely prevents and completely cures the disease, which is now rare. The protagonist of this medical history was James Lind. His report of a prospective controlled therapeutic trial in 1747 preceded by a half-century the British Navy's prevention and cure of scurvy by citrus fruits. After lime-juice was unwittingly substituted for lemon juice in about 1860, the disease returned, especially among sailors on polar explorations. In recent decades revisionist historians have challenged normative accounts, including that of scurvy, and the historicity of Lind's trial. It is therefore timely to reassess systematically the strengths and weaknesses of the canonical saga.

A study was undertaken to investigate the role of Trypanosoma vivax in sheep and goat mortality and abortions in the Brazilian semiarid region, where outbreaks had been previously reported in bovines. For this purpose, 177 goats and 248 sheep (20% of herds) were randomly sampled on four farms in the State of Paraiba in May and October 2008. The animals were screened for trypanosomes by the buffy coat technique (BCT) and PCR. Infected animals, approximately 25% in both surveys, manifested apathy, pale mucous membranes, enlarged lymph nodes, weakness, weight loss, opacity of the cornea, blindness and abortion. However, the animals with acute and severe disease showing the highest levels of parasitemia and fever, which many times resulted in death, were only detected in the first survey. These severely diseased animals exhibited progressive weight loss and had the smallest packed cell volume (PCV) values. During survey 2, done in October 2008 on the same farms, only animals with low parasitemia and normal temperatures, PCV values and body weights were detected. Therefore, animals that spontaneously recovered from acute infection developed chronic and asymptomatic disease. This finding demonstrated for the first time that sheep and goats, which are the most important livestock in the semiarid region of Brazil, may be severely injured by T. vivax infection and also play a role as asymptomatic carriers and important sources of T. vivax to ruminants in general.

The authors describe a case of synchronously occurring (double) tumours, i.e. primary hepatocellular carcinoma and aortic body chemodectoma in a 14-year-old mixed-breed male dog. The tumours were identified during necropsy, following euthanasia. In the last months of its life, the dog showed signs of weakness, anorexia, apathy, inactivity, and abdominal palpation elicited a painful reaction. The primary liver cancer emerged in the left lateral lobe without evidence of any distant metastases. Histopathological and immunohistochemical investigations revealed a well-differentiated, trabecular, claudin-7-, claudin-5- and pancytokeratin-negative hepatocellular carcinoma. The Ki-67 proliferation index was 33%. During necropsy, a synchronously occurring benign, grade I type aortic body chemodectoma was also detected in the dog. This neuroendocrine tumour showed chromogranin-, synaptophysin-, neuron-specific enolase- and S100 protein-positivity, and the Ki-67 proliferation index was 2%. The authors believe that this is the first description of synchronously occurring hepatocellular carcinoma and aortic body chemodectoma in a dog.

Ehrlichiosis is the multiorgan infectious disease caused by small, intracellular rickettsias from the genus Ehrlichia. These microorganisms are known as an etiologic factor of infections world wide in humans and in different species of animals. Dog ehrlichiosis can be caused by several species of Ehrlichia attacking different groups of blood cells, but most often an infection by Ehrlichia canis is diagnosed with special relation to monocytes. A vector for E. canis are Rhipicephalus sanguineus and Ixodes ricinus, commonly occurring in Poland. Disease caused by E. canis is known as Canine Monocytic Ehrlichiosis (CME). The disease most often has an asymptomatic course which can, in favourable circumstances, run into acute or chronic forms. The acute form of CME proceeds usually with fever, apathy, weakness and accompanying respiratory symptoms, lameness and disturbances in blood coagulation. In laboratory examinations thrombocytopenia, anemia and leucopenia are ascertained. The chronic form of CME proceeds among gentle, unspecific symptoms which may last even 5 years. The CME diagnosis is difficult and often demands parallel different diagnostic methods. A medicines of choice in the ehrlichiosis treatment are antibiotics from the group of tetracyclines, given at least for 28 days. They are largely efficient during treatment of the acute CME, causing the quick improvement. Instead, in the case of chronic form, answer for treatment can be weak, and cases of resistance to antibiotics ave known.
