Limitation of a bioterrorist anthrax attack will require rapid and accurate recognition of the earliest victims. To identify clinical characteristics of inhalational anthrax, we compared 47 historical cases (including 11 cases of bioterrorism-related anthrax) with 376 controls with community-acquired pneumonia or influenza-like illness. Nausea, vomiting, pallor or cyanosis, diaphoresis, altered mental status, and raised haematocrit were more frequently recorded in the inhalational anthrax cases than in either the community-acquired pneumonia or influenza-like illness controls. The most accurate predictor of anthrax was mediastinal widening or pleural effusion on a chest radiograph. This finding was 100% sensitive (95% CI 84.6-100.0) for inhalational anthrax, 71.8% specific (64.8-78.1) compared with community-acquired pneumonia, and 95.6% specific (90.0-98.5) compared with influenza-like illness. Our findings represent preliminary efforts toward identifying clinical predictors of inhalational anthrax.

This prospective study was conducted at Bamrasnaradura Hospital from November 11, 2002, until January 5, 2003, in order to describe the clinical manifestations and determine the aetiologies as well as to assess the short-term outcome of interstitial pneumonitis in HIV/AIDS patients. 59 patients with interstitial infiltrates on chest radiographs were included in the study. Tuberculosis (TB) was the most common diagnosis (44%), followed by Pneumocystis pneumonia (PCP) (25.4%), bacterial pneumonia (20.3%) and fungal pneumonia (10.2%). In TB, compared to other diagnoses, a mild cough (p = 0.031), pallor (p = 0.021), lymphadenopathy (p < 0.001), an absence of skin lesions (p = 0.003), a higher mean body temperature (p = 0.004) and an absence of dyspnoea on exertion (p = 0.042) were significant findings. In PCP, compared to other diagnoses, dyspnoea on exertion (p = 0.014), nonpurulent sputum production (p = 0.047), a higher mean respiratory rate (p < 0.001), and an absence of lymphadenopathy (p < 0.001) were significant factors. In bacterial pneumonia, compared to other diagnoses, production of purulent sputum (p = 0.014), haemoptysis (p = 0.006), skin lesions (p = 0.002) and severe cough (p = 0.040) were significantly associated factors. In fungal pneumonia, compared to other diagnoses, headache and papulonecrotic skin lesions were common findings, but no factor showed a significant association. After four weeks, 59.3% patients were alive and 13.6% had died. Among those alive, 88.6% had clinically improved. The cumulative survival after 28 days was highest among PCP patients, followed by bacterial pneumonia, TB and fungal pneumonia, but these differences were statistically not significant (p = 0.453).

A 5-year-old girl with no underlying immune deficiency or hematologic disease was treated with a combination of ceftriaxone and ampicilline-sulbactam for pneumonia. On the ninth day of the therapy, she developed oliguria, paleness, malaise, immune hemolytic anemia (IHA) and acute renal failure (ARF). Laboratory studies showed the presence of antibodies against ceftriaxone. Acute interstitial nephritis (AIN) was diagnosed by renal biopsy. The patient's renal insufficiency was successfully treated with peritoneal dialysis without any complications. The patient recovered without any treatment using steroids or other immunosuppressive agents.

A prospective study was conducted at Bamrasnaradura Hospital, Nonthaburi Province, Thailand from November 11, 2002 to January 5, 2003. A total of 59 HIV/AIDS patients with interstitial infiltrates on chest radiographs were included in the study. The objectives of this study were to describe the clinical manifestations and determine the etiologies of interstitial pneumonitis, assess the short-term outcomes and determine the accuracy of the clinical diagnosis of the etiologies of interstitial pneumonitis in HIV/AIDS patients at Bamrasnaradura Hospital, Nonthaburi, Thailand. Tuberculosis was the most common diagnosis (44%), followed by Pneumocystis carinii pneumonia (25.4%), bacterial pneumonia (20.3%) and fungal pneumonia (10.2%). In tuberculosis, compared to other diagnoses, a mild cough (p = 0.031), pallor (p = 0.021), lymphadenopathy (p < 0.001), absence of skin lesions (p = 0.003), higher mean body temperature (p = 0.004) and an absence of dyspnoea on exertion (p = 0.042) were significant findings. On multivariate analysis, however, only an absence of skin lesions (p = 0.023) remained a statistically significant predictor of TB. In Pneumocystis carinii pneumonia compared to other diagnoses, dyspnea on exertion (p = 0.014), non-purulent sputum production (p = 0.047), a higher mean respiratory rate (p < 0.001), absence of lymphadenopathy (p < 0.001) and lack of purulent sputum (p = 0.030) were significant factors. By multivariate analysis, only an absence of lymphadenopathy were shown to be independently and statistically significantly associated (p = 0.040). In bacterial pneumonia, compared to other diagnoses, production of purulent sputum (p = 0.014), hemoptysis (p = 0.006), pallor (p = 0), skin lesions (p = 0.002) and a severe cough (p = 0.020) were significantly associated factors. On multivariate analysis, none of these factors were statistically significant. In fungal pneumonia, compared to other diagnoses, headache and papulonecrotic skin lesions were common findings, but no factor had a significant association. After four weeks, 59.3% of the patients were alive, 13.6% died and 27.1% were lost to follow-up. Among the alive patients 88.6% had clinically improved. On multivariate analysis, no factor was shown to be a statistically significant predictor of death. The cumulative survival after 28 days was highest among PCP patients, followed by bacterial pneumonia, tuberculosis and fungal pneumonia, but this difference was not statistically significant (p = 0.0453).

Chronic neutropenia is a decrease in circulating neutrophils in the peripheral blood lasting over 6 months. Values need to be refered with the age and race. In children aged 2 weeks to 12 months reffered values are above 1000/03BCL. There are congenital and aquired reasons of neutropenia in infancy. The most common type of chronic neutropenia in infants is chronic, benign neutropenia (AIN). Authors present ten infants between three and six months with chronic, benign neutropenia. The reason of ordering laboratory tests at outpatient clinic were benign upper respiratory tract infections (four cases), pallor (four cases) and on parental demand (one case). In one infant neutropenia was observed during treatment of pneumonia at a district hospital.

The broad spectrum of heat-related injury (HRI) and its associated lesions is well described in the human literature, with rare reports of similar findings in farm animals. In the current case series, lesions from 4 of 8 lambs that presented with clinical signs of heat stress are reported. Gross lesions at necropsy consisted of acute renal swelling and pallor in 2 of 4 lambs, muscle pallor in 2 of 4 lambs, and chronic bronchointerstitial pneumonia in each of the 4 lambs. Histological lesions considered heat-related included acute renal tubular necrosis, pigment casts, tubular epithelial regeneration, multifocal myocyte degeneration, necrosis, and dropout with histiocytic influx and regeneration. Chronic, bronchointerstitial pneumonia, present in each lamb, was considered a condition predisposing to HRI. Compatibility between observed lesions and those reported in human beings with injury secondary to elevated body temperatures established a diagnosis of HRI in these animals. Diagnostic pathologists should consider HRI in lambs with histological evidence of renal tubular necrosis and/or rhabdomyolysis and even in cases where the clinical picture is strongly suggestive but lesions are not demonstrable.

A 2-year-old African-American male patient with sickle cell trait developed cough, red coloured urine, pallor and fatigue. The patient was hospitalised. Diagnostic workup showed that he was glucose 6 phosphate dehydrogenase (G6PD) deficient in erythrocytes. He also had chest X-ray findings of pneumonia. His urine examination showed the presence of haemoglobin and myoglobin. On repeated questioning it was found that he had a moth ball in his mouth a few days prior to this medical episode. This case illustrates a rarely described complication of myolysis in G6PD deficient persons on exposure to a strong oxidant. A review of the literature showed that most people with G6PD deficiency tolerate exercise well without untoward effect in muscles. However, assay of myoglobin in urine has not been routinely performed in these patients during acute haemolytic episode, and thus it is uncertain how frequent myoglobulinaemia occurs in a similar stress situation.

In mid-July 2013, an outbreak of peste des petits ruminants (PPR) was observed in a herd of camels after they were imported from Kuwait to the Khuzestan province in southwest of Iran. The clinical signs of the affected animals included sudden death, fever, oral erosion, and ecthyma like lesions, yellowish diarrhea, pneumonia and respiratory distress, enlargement of lymph node, severe dehydration, dermatitis, ulcerative keratitis, and conjunctivitis. Necropsy findings included keratoconjunctivitis, congestion and consolidation of the lung, paleness of the liver, and enlargement and edema of lymph nodes. Histopathological exam revealed degeneration and acute hyperemia of the lungs, fatty change and necrotic foci in the liver, tubular necrosis in the kidneys, and necrotic dermatitis. We used immunocapture enzyme linked immunosorbent assay (ELISA) to confirm peste des petits ruminants virus (PPRV) and differentiate it from rinderpest virus. Then virus genome was studied by molecular analysis for detecting of strain and substrain of the virus. Immunocapture ELISA of all specimens reacted positively against PPRV antigens. Also, reverse transcription polymerase chain reaction (RT-PCR) results in the lung and lymph nodes of the dead camels consolidated the cause of disease to be PPRV. The present study is the first report of the PPRV outbreak in camels in Iran.

Hemolytic-uremic syndrome (HUS) is a common cause of organic acute renal failure (ARF) in children. It is a progressive complication of acute gastroenteritis (AGE), especially caused by Escherichia coli in children. This study aimed to describe the clinical, therapeutic and evolutionary aspects of this affection in four children. We collected four cases of HUS. The average age was 10,5 months (5-15mois), exclusively boys. Clinical examination revealed a hemolytic anemia (pallor and jaundice), oligoanuria and edematous syndrome (2 cases), arterial hypertension (1 patient), AGE associated with severe dehydration and hypovolemic shock (2 patients), consciousness disorders. ARF was found in all patients as well as thrombocytopenia and schizocytes smear. Direct Coombs test was negative. Hyperkalemia was found in 3 patients, of whom 1 with hyperkalemia level of more than 9.2 mmol/L, hyponatremia at 129 mmol/l (1 patient) and hypernatremia at 153 mmol/l (1 patient). HUS was secondary to pneumococcal pneumonia (1 patient) while AGE was secondary to E. coli (1 patient). The treatment was mainly symptomatic and included fluid restriction, transfusion of red cell concentrates, diuretics, peritoneal dialysis and hemodialysis. The evolution was marked by the onset of chronic renal failure (1 patient) after 6 months of follow-up and by recovery (1 case). Three patients died. HUS is the most common cause of organic acute renal failure in newborns. Diagnosis is essentially biological, treatment is mostly symptomatic.

The sequential pathology of a genotype XIII Bangladeshi strain of Newcastle disease virus (NDV) was studied in 5-weeks old chickens. Layer chickens of ISA Brown breed were inoculated through the intranasal and intraocular routes with the BD-C161/2010 strain of NDV and examined at different times post-infection (pi). NDV-infected chickens showed depression at 3 days pi (dpi) followed by dropped wings, paralysis and death starting at 4 dpi. Lungs of infected chickens showed hemorrhagic lesions starting at 24 hours pi (hpi) that was followed by pallor and slight contraction by 2 to 3 dpi and subsequently developed into severe hemorrhagic pneumonia with mononuclear cell infiltration. Hemorrhagic and necrotizing lesions were found in different visceral organs including proventriculus, intestine, gut-associated lymphoid tissues, liver and kidneys starting at 3 dpi that progressed rapidly. Severe lymphoid depletion was observed in the thymus, spleen and bursa of Fabricius starting at 1-3 dpi followed by hemorrhages, necrosis, inflammation and atrophy at 4-5 dpi. In the brain, mild neuronal lesions such as focal to diffuse encephalitis with encephalomalacia was observed at 2-3 dpi and moderate and diffuse meningoencephalitis with encephalomalacia at advanced stages. In conclusion, the BD-C161/2010 strain of NDV produced lesions typical of velogenic viscerotropic pathotype of NDV.
