A case of primary large cell splenic lymphoma of B lineage exhibiting filiform cell appearance is reported. The patient presented with massive splenomegaly, and following spontaneous splenic rupture, died of adult respiratory distress syndrome. The clinical aspects of the case, notably a lymphoma arising as a primary tumour in the spleen, with spontaneous spleen rupture and rapid fatal outcome, in combination with the filiform appearance of the lymphoma on electron microscopic examination, constitute an unusual combination of features. As far as is known, this B cell neoplasm is only the second primary splenic lymphoma of filiform type to be recorded.

A diagnosis of blood culture-positive typhoid (TF; n = 39) or paratyphoid (PTF; n = 17) fever was made in 56 patients admitted to two Dutch university hospitals in the period 1984-1990. The group of TF patients constituted 9% of the reported national total during those years. A retrospective analysis of available clinical, laboratory and epidemiological data was carried out. Without exception, infections were contracted during travel abroad, especially to India and Indonesia. The clinical features and the response to antimicrobial treatment of TF and PTF proved essentially the same. Fever, headache and anorexia were important symptoms; rose spots and splenomegaly were found in 18/38 and 10/39 with S. typhi respectively. Most patients had a normal white blood cell count; less than half of the patients had thrombocytopenia. A positive Widal-test was found in 15/24 patients with S. typhi. 18/39 patients with S. typhi had been vaccinated; 10 did not know. Amoxycillin was the preferred antimicrobial agent in 69% of cases. Median defervescence time was 5 days in TF and 4 days in PTF. Relapse occurred in 3 TF cases. The recurrence rate after amoxycillin treatment was 7.6%. Profuse intestinal bleeding (1x), septic shock (1x) and cholangitis plus ARDS (1x) were major complications, seen in TF patients only. All patients recovered fully. None of the isolated strains of S. typhi or S. paratyphi proved multiresistant. Surveillance data from the Dutch National Institute of Public Health and Environmental Protection suggest that multidrug-resistance of S. typhi is increasing, especially in strains imported from countries such as India and Pakistan.(ABSTRACT TRUNCATED AT 250 WORDS)

A case is reported of a previously healthy 52-year-old African American male who presented with acute onset of abdominal pain. Progressive increase in his abdominal symptoms led to an exploratory laparotomy; however, no pathology was discovered. Postoperatively, the patient became hypoxemic which progressed to diffuse infiltrates on chest x-ray, suggestive of adult respiratory distress syndrome. He had a rapidly fatal course. Autopsy showed bone marrow infarction, fat embolism, splenomegaly, and widespread congestion with sickle erythrocytes. Hemoglobin electrophoresis done postmortem showed hemoglobin (Hb) SC disease that was undiagnosed antemortem. To the best of our knowledge, it is unusual for Hb SC to be diagnosed postmortem in adults. This case suggests that sickle cell disorders should be ruled out in patients at risk for hemoglobinopathy in the presence of signs and symptoms compatible with the disease, irrespective of age.

Clinical observations of Babesia canis infection in 63 dogs during a 1-year period are summarised, demonstrating the pathogenicity of the Babesia strain endemic in Hungary. Most patients had babesiosis in the spring and autumn, correlating with the seasonal activity of ticks. Male animals appeared in higher numbers, probably due to an overrepresentation of outdoor dogs. Uncomplicated babesiosis was diagnosed in 32 cases. The disease affected dogs of any age in this study. Symptoms were similar to those published from other parts of the world: lethargy, fever, splenomegaly, pallor, icterus, haemoglobinuria and presence of ticks were the most common observations. Thrombocytopenia, lymphopenia and neutropenia were frequent haemogram changes. Imidocarb appeared to be highly effective in eliminating the Babesia infection. Thirty-one animals demonstrated babesiosis with complications. Most Rottweilers (7/9) developed complicated disease. Old age was a risk factor for multiple complications. Multiple organ manifestations had poor prognosis. Hepatopathy (44%), pancreatitis (33%), acute renal failure (ARF; 31%) and disseminated intravascular coagulation (DIC; 24%) were frequent complications, while immune-mediated haemolytic anaemia (IMHA; 10%), acute respiratory distress syndrome (ARDS; 6%) and cerebral babesiosis (3%) were rarely observed. There was a significant difference between the mean age of dogs having uncomplicated disease, babesiosis with a single complication and babesiosis with multiple complications (3.4, 4.8 and 8.6 years, respectively, p < 0.001). The recovery rate (78, 68 and 25%, respectively, p = 0.005) and mortality rate (3, 21 and 67%, respectively, p < 0.001) also tended to differ significantly in these groups. Systemic inflammatory response syndrome (SIRS) and DIC are two possible pathways leading to multiple organ dysfunction syndrome (MODS) in babesiosis. DIC was found to predict MODS more sensitively in this study than SIRS: there were 6 animals developing MODS out of 11 identified with DIC, while only 5 dogs developed MODS out of 22 having SIRS.

Rickesttsial diseases are a group of diseases caused by obligate intracellular gram negative bacilli and transmitted to man by arthropod vectors (except Q fever). It is increasingly realised that rickesttsial diseases are underdiagnosed. It is now well documented that rickettsial disease is prevalent all over India, in pockets. The hallmark of rickettsial infection is microvasculitis, causing microinfarcts in various organs. Usually the patients present with classical triad of Fever, Headache & Rash. Apart from this, pain in legs, oedema, Gastro-intestinal symptoms, hepato-splenomegaly, anaemia, necrotic rash, gangrene of digits, toes, earlobes, scrotum, painless eschar and lymphadenopathy are other manifestations. Complications include encephalitis, ARDS, pneumonia, Myocarditis, Renal failure and Vascular collapse. Endocarditis is seen in Q fever. Gold standard test for confirmation of diagnosis is I.F.A. Weil felix test is widely available but unacceptable for accurate diagnosis. Weil Felix test can be used in developing countries where other tests are not available. ELISA Should be preferred and is now available in India. The drug of choice for all age group is doxycycline. Rickettsia are potentially dangerous pathogens and unfortunately, specific serological tests are available in only a few specialized laboratories. Hence, it is imperative to have a high index of suspicion for Rickettsial diseases and make a clinical diagnosis based on prudent history taking and appropriate physical findings. A therapeutic trial with a specific agent in these patients is justified because a delay in initiating treatment may prove fatal. A rapid and favorable response is suggestive of a correct diagnosis.

Macrophage Activating Syndrome (MAS) is a life-threatening disease seen in autoimmune diseases including lupus erythematosus, rheumatoid arthritis, Still's disease, polyarteritis nodosa. It is characterized by fever, pancytopenia, liver failure, coagulopathy, and neurologic symptoms and high serum ferritin. A 27 yr. old female patient was admitted in shahid Mostafa Khomeini Hospital (Tehran-Iran) in May 2011 because of lower extremities edema and ascites and fever from 1.5 month ago. In physical examinations she had generalized lymphadenopathy, splenomegaly and pleural effusion. In laboratory tests she had pancytopenia, positive ANA and Anti DNA (ds), hypocomplementemia, hypertriglyceridemia and high ferritin level. Gradually she had signs of RPGN and ARDS. The patient had no skin and musculoskeletal signs of SLE and no liver failure nor coagulopathy of MAS. Her lymph node biopsy was reported as Castleman syndrome. Unlike other studies, the patient showed MAS before treatment with cytotoxic for lupus nephritis.
