The patient had severe hypogammaglobulinemia, which is a possible complication of rituximab therapy. To our knowledge and after reviewing the available medical literature, this is the first described case of purulent meningitis caused by Leuconostoc sp. in a patient with mantle cell lymphoma that appeared after treatment with the R-CHOP protocol. The diagnosis of purulent meningitis was based on clinical, laboratory and cytological cerebrospinal fluid findings, in addition to blood culture results in which we isolated Leuconostoc sp. The patient was treated with meropenem with full recovery.

The aim of the study was to assess the prevalence of leukocytosis in our sample of patients with lung carcinoma, to determine if leukocytosis is more common with a particular type of lung carcinoma, and whether leukocytosis caused inappropriate prescribing of antibiotics in patients with lung carcinoma. Methods: The study included 100 lung carcinoma patients treated at Department of Lung Diseases, General Hospital, during a three-year period (2003-2006). The methods of descriptive statistics were used on statistical analysis. Results: during a three-year period (2003-2006), 100 patients with lung carcinoma were treated at General Hospital, 23% of them with leukocytosis as a paraneoplastic phenomenon. Antibiotic therapy was prescribed in five of 23 (1,25%) patients. Conclusion: leukocytosis was most frequently associated with squamous cell carcinoma of the lung (43%), however,...

In 14 malignant lymphoma patients, 16 18F-FDG PET procedures were performed to assess chemotherapy and/or radiotherapy outcome (remission). One patient with clinically overt relapse of non-Hodgkin's lymphoma underwent PET to assess disease dissemination prior to prescribing second-line chemotherapy. Two patients were submitted to PET on two occasions. PET pointed to residual disease in six of 14 patients and was inconclusive in one patient. These patients underwent computed tomography (CT), some of them before and others after PET examination. Then PET and CT findings were compared and therapeutic response, i.e. disease remission was assessed. The signs of residual disease were present in four and absent in nine patients, whereas inconclusive findings in terms of residual disease we...

An 18-year-old female was admitted on March 17, 1997 to the Department of Infectious Diseases for fever, chills and failure to thrive. Physical examination revealed a palpable tumorous mass in the iliac region on the right. The patient was transferred to the Department of Surgery. Vaginal examination and echotomography of the abdomen and pelvis minor were performed and revealed the presence of an irregular, inhomogeneous tumorous formation of 8 cm in diameter in the pelvis minor, differentially diagnostic right ovary, i.e. acute adnexitis or perityphlitic tumor. After that, small intestine resection, tumor excision in toto, and appendectomy were performed on April 16, 1997. Pathohistological diagnosis was hemangiopericytoma and chronic appendicitis. The biological behavior of this tumor is difficult to predict on the basis of clinical and morphological parameters. In our patient, local tumor excision was not followed by adjuvant therapy. After ten years, the patient is well, healthy and a mother of two healthy children.

Axilla is the most common site of occurrence, but locations like scalp, anogenital region, ear canal, chest, wrist, finger and eyelid have been described. The neoplasm presents itself as an asymptomatic, slow-growing, solid or cystic mass that varies in color. Most patients have a history of a long-standing neoplasm before the diagnosis is made. The disease is considered to have an indolent clinical course with favorable outcome although more than half of reported patients had regional lymph node metastases at the time of diagnosis. Systemic dissemination to lung, bones, liver and brain is extremely rare with only 14 cases documented in the literature. Wide surgical excision with lymph node dissection upon confirmation of the lymph node metastases remains the only curable treatment. Care and management of the disseminated disease is still challenging. We report a case of a 65-yea...

Croatian Cooperative Group for hematologic disorders, KROHEM proposes the diagnostic and treatment guidelines for ET. Diagnosis of ET is based on the criteria and classification of World Health Organization (WHO). The level of treatment recommendation is based on the UpToDate (web based medical community database) criteria. For ET diagnosis it is mandatory to show sustained increased number of platelets with typical histomorphological changes of megakaryopoiesis in bone marrow. Secondary thrombocytosis and other chronic myeloproliferative neoplasms have to be excluded. Therapy is based on risk factors for ET. The risk factors are number of platelets, patient's age, and the risk levels for thrombosis and bleeding. Patients with low risk (age < 60 years and platelets < 1000 x 10(9)/L) arw not candidates for therapy. In younger group of patients with platelets between 1000 and 1500 x 10(9)/L or more than ...

Analyzed were 364 cytological and pathohistiological samples taken from 335 patients having suspected diagnosis of gastric cancer. Every specimen was submitted to slide imprinting and then fixed in formalin for further processing with routine histopathology. The imprints were air dried for cytological analysis, stained according to May-Grünwald-Giemsa and analyzed by light microscope. By pathohistological punch-biopsy samples analysis stomach cancer was found in 45 samples. With cytological samples analysis the cancer was detected in 48 samples and 13 cytological samples were suspected of cancer With combining these two methods cancer was found in 68 cases. Patients with positive cytological finding and negative pathohistologic finding underwent gastroscopy with punch-biopsy. All patients with positive pathohistological findings were operated. All materials were histol...

We report a case of a 50-year-old woman with novel influenza A (H1N1) infection complicated by pericardial effusion. Resolution of both symptoms and pericardial effusion occurred after a treatment with oseltamivirin and ibuprofen. There were no signs of acute left or right ventricle dysfunction. Pericarditis and pericardial effusion are occasionally associated with influenza A infections. To our knowledge, this is a rare case of pericardial effusion associated with influenza A (H1N1) reported during the current novel influenza A (H1N1) pandemic that responded well to conservative management.

However, the immune impairment may also involve noncartilaginous tissues such as kidneys, blood vessels, etc. The disease may occur as a primary disorder or in association with other diseases. The case of a female patient with concurrent manifestation of myelodysplastic syndrome-refractory anemia with excess blasts, and relapsing polychondritis, is presented. The diagnosis of relapsing polychondritis was established ten months after the diagnosis of myelodysplastic syndrome, when the criteria for the former were met. Total hearing loss and blindness developed soon thereafter.
