With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with
systemic disease
of unknown origin and
splenomegaly
, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear
systemic disease
were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode of Still's disease. One patient with a known immunodeficiency syndrome (stage C III) showed multiple hypodense lesions in the spleen. Biopsy allowed a diagnosis of mycobacterial infection, with identification of Mycobacterium tuberculosis. No major complications occurred in any of the four cases; post-biopsy bleeding was observed in three of the four, but was easily managed by argon plasma coagulation or application of fibrin glue, or both. We recommend the use of spleen biopsy as a diagnostic tool in splenopathy of unknown origin if previous diagnostic methods have failed to yield a definitive diagnosis.

Adult Still's disease is a
systemic disease
of unknown etiology. We report a retrospective study of 11 cases (9 females and 2 males) of adult Still's disease collected during 25 years. The mean age was 36 years. Fever, arthritis and skin rash was constant. Adenopathies and
splenomegaly
were observed in 2 patients. The laboratory findings was characterized by a constant inflammatory syndrome and leucocytosis. Hypertransaminasemia and hyperferritinemia were observed respectively in 7 cases and 3 cases. Corticosteroids were prescribed in all patients. Methotrexate was administered in 3 patients. Outcome was favorable in 10 cases, death incurred in one patient, secondary to acute hepatitis.

Strains of Sporothrix schenckii preserved under mineral oil were examined for virulence in BALB/c mice. The mice were inoculated with S. schenckii conidia and development of cutaneous lesions, signs of inactivity, weight loss, survival rates, number of viable yeast cells in lung and spleen,
splenomegaly
and organ lesions were evaluated. After intravenous injection of 7.5 x 10(6) conidia, two of five S. schenckii strains were unable to induce
systemic disease
and to kill the mice, only producing cord-like lesions on the tail that regressed with mouse maturation. Very small numbers of viable cells isolated from the spleen confirmed the lower invasive ability of these strains when compared with other strains studied here. These results suggest a relationship between the attenuation of virulence and the storage method under mineral oil after long periods of time.

A 55-years-old male, who presented with insidious onset gradually progressive sensorimotor polyneuropathy, POEMS-syndrome was diagnosed based on polyneuropathy,
splenomegaly
, hypothyroidism, the presence of IgG-monoclonal serum protein with osteosclerotic lesions and hyperpigmention of skin. Biopsy of the osteosclerotic lesion from the right superior pubic rami was consistent with plasmocytoma. Electrophysiological studies revealed demyelinating sensorimotor neuropathy and biopsy from sural nerve showed demyelinating neuropathy with secondary axonopathy. The patient showed improvement with radiotherapy. This is a rare
systemic disease
from the clinical spectrum of plasma cell dyscrasias with polyneuropathy. The importance of POEMS syndrome in the differential diagnosis of polyneuropathies has been emphasized.

Paracoccidioidomycosis (PCM) in children is rare, and its clinical progression is not clearly understood. The admission and post-admission clinical records of 38 children and teenagers aged up to 14 were studied who had been under treatment for 24-30 months. It is a consecutive case series, 17 retrospective and 21 prospective, from 1977 to 2000, admitted before and after 1990, respectively. The main clinical presentations were lymphatic, abdominal and cutaneous involvement, and fever. The alterations which disappeared more slowly were lymphadenomegaly, hepatomegaly,
splenomegaly
, and osteoarticular pain. Poor intestinal absorption, esophageal varices and splenic calcification were observed before treatment and persisted as sequelae. There was a satisfactory response to initial treatment in 56.7% of cases. Half the patients became asymptomatic in the ninth month of treatment, and 17+/-8% of cases presented with at least one symptom of the disease after 30 months of treatment. There were five deaths, and treatment failure was frequent and associated in part with the irregular use of antifungal. Treatment with ketoconazole was safe and effective. PCM is a serious
systemic disease
with slow evolution and high lethality, requiring treatment maintenance for a minimum of 24 months with careful and prolonged follow-up. Studies are necessary to evaluate the efficacy of different antifungals and the ideal treatment length for children with PCM.

Symptoms of human leishmaniasis range from subclinical to extensive
systemic disease
with
splenomegaly
, hepatomegaly, skin lesions, anemia and hyperglobulinemia, but the basis of this variation is unknown. Association of progression of the disease with Th2 lymphocyte response was reported in mice but not in humans. As most genetic studies in Leishmania major (L. major)-infected mice were restricted to skin lesions, we analyzed the symptomatology of leishmaniasis in mice by monitoring skin lesions, hepatomegaly,
splenomegaly
and seven immunological parameters. We detected and mapped 17 Leishmania major response (Lmr) gene loci that control the symptoms of infection. Surprisingly, the individual Lmr loci control 13 different combinations of pathological and immunological symptoms. Seven loci control both pathological and immunological parameters, 10 influence immunological parameters only. Moreover, the genetics of clinical symptoms is also very heterogeneous: loci Lmr13 and Lmr4 determine skin lesions only, Lmr5 and Lmr10 skin lesions and
splenomegaly
, Lmr14 and Lmr3
splenomegaly
and hepatomegaly, Lmr3 (weakly) skin lesions, and Lmr15 hepatomegaly only. Only two immunological parameters, IgE and interferon-gamma serum levels, correlate partly with clinical manifestations. These findings extend the paradigm for the genetics of host response to infection to include numerous genes, each controlling a different set of organ-specific and systemic effects.

Still's Disease of the adult is a
systemic disease
that the cause is unknown. If the pediatric forms are frequent, the affection of the adult is rare and its diagnosis is difficult. The purpose of this study is to analyse the features of the clinical evolution of adult Still's disease and to compare our results with the literature. It is a retrospective study about 21 years that permitted to collect 11 cases according the criteria of Yamaguchi. It is a matter of 6 men and 5 women that the mean age is 31 years old (age range: 16 to 48 years old). The fever was constant, the skin rash was noticed in 8 patients (72.7%); a polyarthritis was noticed in all the patients, chronic in 10 cases (90.9%) which 2 erosive forms. Adenopathies were present in 5 patients, a
splenomegaly
and a hepatomegaly were noticed respectively in 4 and 2 cases. Inflammatory syndrome with hyperleukocytosis was constant, and a hepatic cytolysis was noticed in 80%. The total ferritinemia titrated in 8 patients was constantly high. The hemocultures realized in all the patients were sterile and the complete immunologic examination was negative. The strong dose of corticoid was prescribed with success in all the patients. The immediate evolution was favourable in 10 patients. We deplore one death after a state of deep denutrition. Still's disease of the adult is rare, its diagnosis is difficult, sensitive to corticotherapy and its clinical evolution in our country is comparable to the literature.

Francisella tularensis can cause severe disseminated disease after respiratory infection. The identification of factors involved in mortality or recovery following induction of tularemia in the mouse will improve our understanding of the natural history of this disease and facilitate future evaluation of vaccine candidate preparations. BALB/c mice were infected intranasally with the live vaccine strain (LVS) of F. tularensis subsp. holarctica and euthanized at different stages of disease to analyze the induction of immune molecules, gross anatomical features of organs, bacterial burdens, and progression of the histopathological changes in lung and spleen. Tissue-specific interleukin-6 (IL-6), macrophage inflammatory protein 2, and monocyte chemotactic protein 1 were immune markers of mortality, while anti-LVS immunoglobulin M and IL-1beta were associated with survival. Moribund mice had enlarged spleens and lungs, while surviving mice had even more prominent
splenomegaly
and normal-appearing lungs. Histopathology of the spleens of severely ill mice was characterized by disrupted lymphoid follicles and fragmented nuclei, while the spleens of survivors appeared healthy but with increased numbers of megakaryocytes and erythrocytes. Histopathology of the lungs of severely ill mice indicated severe pneumonia. Lungs of survivors at early time points showed increased inflammation, while at late times they appeared healthy with peribronchial lymphoid aggregates. Our results suggest that host immune factors are able to affect bacterial dissemination after respiratory tularemia, provide new insights regarding the pathological characteristics of pulmonary tularemia leading to
systemic disease
, and potentially identify immune markers associated with recovery from the disease.

Canine leishmaniosis is a severe
systemic disease
caused by the kinetoplastid protozoan Leishmania infantum, an obligatory intracellular parasite of mammalian macrophages, transmitted by the bite of phlebotomine sandflies. The infection in dogs might occur without any clinical signs or might be characterised by chronic viscerocutaneous signs, such as lymphadenopathy, skin lesions,
splenomegaly
, onychogryphosis, and renal as well as ocular damage due to immunocomplex deposition. In atypical cases the parasites can be found in the striated musculature, the central nervous system, the endocrine glands or gonads, with or without functional damage. Leishmania infection might seldom induce oral lesions, particularly on the tongue. The authors describe the clinical case of a four-year old mongrel dog with tongue lesions caused by L. infantum. The dog was presented due to diarrhoea, lack of appetite and hypersalivation. Examination of the oral cavity revealed the presence of multiple red, nodular lesions on the dorsal and lateral surfaces of the tongue. Definite diagnosis of an infection with L. infantum was obtained by an indirect immunofluorescence antibody test (IFAT) and by the cytological identification of the parasite in nodular, lingual lesions and bone marrow aspirates. The dog was treated with a combination of miltefosine (Milteforan(R), Virbac), 2 mg/kg orally once a day for four weeks and allopurinol (Ziloric(R), GlaxoSmithKline), 10 mg/kg orally twice a day for six months. At the end of the treatment, the animal showed full remission of clinical signs. The authors outline the atypical manifestations in the oral cavity in combination with a L. infantum infection and discuss the therapeutic potential of the combination treatment of miltefosine and allopurinol in canine leishmaniosis.

Ferret systemic coronavirus infection (FSCV) is a
systemic disease
in ferrets that clinically and pathologically resembles the dry form of FIP. The present study describes abdominal imaging features of 11 ferrets with FSCV. Abdominal survey radiographs were available for eight ferrets and ultrasound examination for all cases. Loss of lumbar musculature, decreased peritoneal detail, presence of mid-abdominal soft-tissue masses and
splenomegaly
were the most significant radiographic signs in these patients. Ultrasonographic findings including peritonitis, abdominal lymphadenopathy,
splenomegaly
, abdominal soft-tissue masses, nephromegaly and changes in the renal cortex echogenicity were recorded in the majority of cases with FSCV. As an imaging modality, ultrasound is superior to radiology when abdominal contrast is reduced, as it frequently occurs in these cases. However, although imaging techniques provide additional information in the antemortem diagnosis, they can not replace the definitive diagnosis based on histological and immunohistochemical results.
