Idiopathic inflammatory bowel disease was the diagnosis for 58 dogs and 26 cats, with signs of persistent gastroenteritis, failed responses to dietary trials, and histologic evidence of cellular infiltrates unrelated to other causes of gastrointestinal tract inflammation. Clinical signs of large intestinal dysfunction, watery diarrhea, vomiting, and anorexia with weight loss were common. Nonspecific hematologic, biochemical, and radiographic abnormalities frequently were observed. Mucosal biopsy specimens, obtained endoscopically, were histologically evaluated for severity of mucosal epithelial damage. Mucosal erythema, friability, enhanced granularity, and ulceration or erosion were the predominant endoscopic lesions. Inflammatory bowel disease lesions of moderate severity predominated in the stomach, duodenum, and colon. Lymphocytic/plasmacytic infiltrates were limited to the lamina propria in biopsy specimens from all regions of the gastrointestinal tract. Inflammatory bowel disease commonly is associated with chronic gastroenteritis in dogs and cats.

The human parvovirus B19 agent causes infectious erythema (fifth disease). However, a wide range of other pathological manifestations may also be seen: atypical exanthema, ARD (also obstructive forms, e.g. bronchiolitis), acute gastroenteritis, chronic anemia or aplastic crises (in constitutional or malignant hematological diseases or immunological deficiency), arthralgia/arthritis (e.g. rheumatoid arthritis, jcA), diseases of the central nervous systems (e.g. febrile convulsions in young children), lymphadenopathies (e.g. lymphadenitis mesenterialis or pseudoappendicitis); prenatal infection can lead to fetal death (not malformations!). Infection occurring concomitantly with vaccination may suggest complications of the latter. To clarify the true etiological situation, modern laboratory investigations are then required. Vaccination against parvovirus B19 (initially indicated in the case of non-immune girls and women wanting children) is a desirable future development.

The Human Parvovirus (HPV) like other Parvovirus is a single strand DNA virus with autonomous replication which measures 23mm. Infection with this virus is followed by a non-specific viral syndrome during the prodrome, leading to viremia, which may be followed by arthropathy and/or different kind of rash including the syndrome called erythema infectiosum. It has also been related to an increase in the number of spontaneous abortion in pregnant women with acute infection; and it is the etiology of the aplastic crisis in patients with hemolytic anemias. Many other Parvovirus serologically different from HPV are present in stools and are responsible for acute infectious non bacterial gastroenteritis in people more than 5 years old.

A male infant was born with generalized erythroderma and scaling; the newborn demonstrated poor neonatal development and developed several complications such as hypernatremic dehydration, septicemia, gastroenteritis and seizures. In the neonatal period, the erythema faded, but exfoliation persisted. The parents are healthy but related. One older brother, who died at the age of 3 months, had shown the same clinical picture in the neonatal period and was diagnosed with congenital psoriasis. All clinical investigations, including serum immunoglobulins, complement levels and lymphocyte counts, were normal. Only raised total IgE and multiple positive specific IgE reactions were noted. Skin biopsy revealed an image of ichthyosis. Polarization microscopy of scalp hair showed trichorrhexis nodosa and discrete focal twisting of the hair shaft. This clinical picture and all histological findings are compatible with the indications of Netherton's syndrome. The purpose of this report is to call attention to this severe presentation of congenital ichthyosis in the neonatal period and to the difficulty of a correct diagnosis when confronted with congenital erythroderma.

A previously healthy 7-year-old white boy presented to St. Louis Children's Hospital with a 1-day history of headache, malaise, temperature of 38.7 degrees C, and a progressively erythematous, tender calf with central dusky purpura. On the morning of admission, his mother noticed a 2-mm crust on the patient's right calf with a 3-cm x 3-cm area of surrounding erythema. No history of recent trauma or bite was obtained. He had suffered two episodes of nonbloody, nonbilious emesis during the last day. In addition, over the previous 12 h, he presented brown urine without dysuria. His mother and brother had suffered from gastroenteritis over the previous week without bloody diarrhea. On initial physical examination, there was a 6-cm x 11-cm macular tender purpuric plaque with a central punctum on the right inner calf, which was warm and tender to the touch, with erythematous streaking towards the popliteal fossa (Fig. 1). The inguinal area was also erythematous with tender lymphadenopathy and induration, but without fluctuance. Laboratory studies included an elevated white blood cell count of 20, 800/microL with 6% bands, 86% segs, and 7% lymphocytes, hemoglobin of 12.5 g/dL, hematocrit of 35.1%, and platelets of 282,000/microL. The prothrombin time/activated partial tissue thromboplastin was 10. 4/28.0 s (normal PT, 9.3-12.3 s; normal PTT, 21.3-33.7 s) and fibrinogen was 558 mg/dL (normal, 192-379 mg/dL). Urinalysis showed 1+ protein, 8-10 white blood cells, too numerous to count red blood cells, and no hemoglobinuria. His electrolytes, blood urea nitrogen (BUN), and creatine were normal. The urine culture was negative. Blood culture after 24 h showed one out of two bottles of coagulase negative Staphylococcus epidermidis. The patient's physical examination was highly suggestive of a brown recluse spider bite with surrounding purpura. Over the next 2 days, the surrounding rim of erythema expanded. The skin within the plaque cleared and peeled at the periphery. The coagulase negative staphylococci in the blood culture were considered to be a contaminant. Cefotaxime and oxacillin were given intravenously. His leg was elevated and cooled with ice packs. The patient's fever resolved within 24 h. The lesion became less erythematous and nontender with decreased warmth and lymphadenopathy. The child was discharged on Duricef for 10 days. Because the patient experienced hematuria rather than hemoglobinuria, nephritis was suggested. In this case, poststreptococcal glomerulonephritis was the most likely cause. His anti-streptolysin-O titer was elevated at 400 U (normal, <200 U) and C3 was 21.4 mg/dL (normal, 83-177 mg/dL). His urine lightened to yellow-brown in color. His blood pressure was normal. Renal ultrasound showed severe left hydronephrosis with cortical atrophy, probably secondary to chronic/congenital ureteropelvic junction obstruction. His right kidney was normal.

Infectious complications caused by genus Ehrlichia were confirmed when samples taken from patients with Lyme borreliosis with non-characteristic development and those sent directly by physician who treated the patient were examined. Laboratory diagnostics of ehrlichiosis was based on hematological examination of blood, on anamnestic and epidemiological data, on indirect immunofluorescence serology verified using Western blot test with specific antigen and by determination of DNA agents using polymerase chain reaction analysis (PCR). From 37 goal-directed examinations done in years 1998-2000, bacteria Ehrlichia chaffeensis was found to be the cause of human monocytic ehrlichiosis (HME) in two patients who had stayed in Bulgaria, USA and Thailand. DNA of E. chaffeensis was confirmed by PCR with subsequent product sequentiation (determination of the order of pairs of the oligonucleotide bases). In both patients monocytosis and positive antibodies in indirect immunofluorescence were found. The agent of human granulocytic ehrlichiosis (HGE) caused by group Ehrlichia phagocytophila was determined in three serologically positive patients using PCR and Western blot test with specific antigen P44. Cocobacils were identified electronmicroscopically in intracytoplasmatic vacuoles of isolated leukocytes. Coincidence of Borrelia afzelii and Ehrlichia sp. was found in the blood of a woman patient with erythema migrans formed in the place where from the tick's nymph was removed one week earlier. Cutaneous manifestations were accompanied by subfebrilia, myalgia and gastroenteritis. The patient was positive for both agents in Western blood and PCR. DNA of Borrelia and Ehrlichia was isolated from the patient's blood and urine in the first week of illness. Further study and an increase of sensitivity of the g. Borrelia and Ehrlichia cultivation become necessary to clarify the role of ehrlichias in the disease in our conditions.

Epidemic dropsy is caused by consumption of mustard oil contaminated with argemone oil. It usually occurs in outbreaks with acute manifestation of bilateral pitting edema, erythema, and local tenderness along with cardiac and respiratory problems in severe cases leading to death. We report an outbreak that is unusual because of its gradual onset, clustering in a single family, and with major manifestation of gastrointestinal illness mimicking acute gastroenteritis, hence leading to delayed diagnosis and high mortality. Thus, the diagnosis of epidemic dropsy should be considered as a strong possibility when there is clustering of cases in a single family with on and off gastrointestinal symptoms of vomiting and diarrhea in a mustard oil consuming belt.

Helicobacter cinaedi is an emerging Gram-negative spiral bacillus that was first reported in 1984. It has been implicated as a cause of gastroenteritis and bacteraemia in immunocompromised individuals. Helicobacter cinaedi-associated bacteraemia is sometimes accompanied by skin lesions; however, the cutaneous manifestations of this pathogen are not widely known. To our knowledge, a comprehensive review with detailed analysis of skin lesions associated with H. cinaedi has not been conducted. This article summarizes the clinical appearance of H. cinaedi cellulitis and its management. In addition, we conducted a retrospective review of 73 patients with H. cinaedi bacteraemia at a single institution, to further clarify the characteristic cutaneous features. It was found that 30% (22/73) of the cases of H. cinaedi bacteraemia had sudden-onset erythema accompanied by high fever. The most common cutaneous symptom of H. cinaedi bacteraemia was found to be mild cellulitis, appearing as multiple painful infiltrated erythemas on the extremities. As H. cinaedi is not always detectable in routine blood culture techniques, evaluation of these characteristic cutaneous manifestations seems important in diagnosis. Helicobacter cinaedi infection should be added to the diagnostic list of unspecified fever with painful infiltrated erythemas.

Human parechoviruses (HPeVs) are single-stranded, positive-sense RNA viruses and are classified in the genus Parechovirus of the family Picornaviridae. Echovirus 22 and 23 were reclassified as HPeV1 and 2 in 1999. Although HPeVs were considered to be one of the common viruses which cause mild gastroenteritis and respiratory infections, the concept of HPeVs has changed significantly after the discovery of HPeV3 in 2004. HPeV3 infection is an emerging infectious disease which attracts the attention of pediatricians, because it can cause sepsis and meningoencephalitis in neonates and infants younger than 3 months, which could lead to neurological sequelae and death. In Japan, the epidemics of HPeV3 infection have occurred every 2 or 3 years since 2006 and we had an epidemic in 2014 summer. Fever, severe tachycardia, poor activity and appetite are typical symptoms of HPeV3 infection.In addition, abdominal distention, umbilical protrusion, palmar-plantar erythema,and mottled skin are occasionally observed in patients with HPeV3 infection. Currently diagnosis is usually made by PCR using serum and/or cerebrospinal fluid. The reason why severe disease occur only in neonates and young infants remain unknown; however, negative or low maternally derived neutralizing antibody titers to HPeV3 are suggested to be a risk factor for developing severe HPeV3-related diseases in neonates and young infants. So far, no specific antiviral therapy is available, thus supportive care is the only option. It is likely that epidemics of HPeV3 continue to occur given there are children with absence or lack of neutralizing antibodies against HPeV3. The research related to HPeV3 pathogenesis, specific therapy, and prevention are definitely warranted.
