Obstructive pseudotumor of tuberculosis in a young woman: a rare presentation.

Retroperitoneal pseudotumor is an extremely rare presentation of extrapulmonary tuberculosis. The diagnosis of this paucibacillary disease is difficult which is usually misdiagnosed as a malignant tumor. High index of suspicion is required for early diagnosis and treatment of retroperitoneal pseudotumor which can affect prognosis of this disease. Because of its rarity and difficult diagnosis, we report an 18-year-old immunocompetent girl who presented with abdominal pain and vomiting. Upper endoscopy showed an exudative mass between the second and third parts of duodenum. Abdominal computed tomography (CT) revealed a large retroperitoneal mass with extension into small bowel. Exploratory laparotomy and histopathological examination of tissue showed calcified granuloma. Ziehl-Neelsen staining and PCR confirmed the tuberculosis. The patient was successfully treated with standard antituberculosis therapy.

Estimated incidence of cardiac contusion using transthoracic echocardiography in patients suffering from severe blunt trauma to the chest.

BACKGROUND: Cardiac contusion (CC) is a known complication of blunt trauma to the chest. There have been debates about its true incidence and there are different reports which claim that it occurs in less than 10% to more than 70% of patients. The goal of this study is to estimate the incidence of CC in patients with severe blunt chest trauma (SBCT) using transthoracic echocardiography (TTE). METHODS: After defining inclusion and exclusion criteria, all cases with clinical evidences of SBCT from February 2010 until October 2011 were included in this study. Patients were assessed using electrocardiography (ECG) and transthoracic echocardiography (TTE). Transient echocardiographic changes, including wall motion abnormalities, valvular or papillary muscle dysfunction, pericardial effusion or tamponade, free wall rupture and interatrial/interventricular septum defects, were considered to be abnormal and trauma-related. RESULTS: A total of 210 patients were assessed for CC. Fifty-two trauma-related echocardiographic changes in 47 patients were observed, in which 34 cases had simultaneous transient ECG changes. The estimated incidence of CC in these subjects was calculated to be 23.38% and 16.19%, respectively. There was a statistically significant relationship between the presence of both echocardiographic changes and ECG abnormalities, and those subjects without ECG changes (P = 0.03). As we evaluated stable patients without any cardiac-related clinical manifestations and TTE was chosen as our diagnostic modality, we claim that the true incidence must be higher. CONCLUSIONS: We believe that a comparison of our findings with those presented in the literature shows that the actual incidence of CC in blunt chest trauma is underestimated.

Psychosocial disabilities in patients with schizophrenia.

BACKGROUND: This study aimed at revaluating the psychosocial disabilities in schizophrenic patients. METHODS: In an analytic-descriptive setting, schizophrenic patients were evaluated in Razi University Hospital during a one-year period (2009-10). The study group consisted of male and female patients aged 18-65 years, with the onset of disease for a minimum of 2 years and at least one psychological hospitalization in their medical record. The demographic data, as well as the results of the SANS, SAPS, GARF and SOFAS questionnaires were determined in each patient. RESULTS: Two hundred and eight patients, 53 females, and 155 males with the mean age of 36.96±11.55 (18-65) years were enrolled. Vocational, educational, social, familial, and self-hygiene related disabilities were seen in 63.5%, 21.2%, 93.8%, 13.9%, and 48.1% of the patients, respectively. Totally, psychosocial disabilities were reported in 98.1% of these patients. The mean age of the patients with educational or social disabilities was lower. Vocational problems were more common in male patients. Familial and social disabilities were positively related to the severity of positive and negative symptoms, with the predominance of the latter. Positive and negative symptoms were more frequent in patients with social and self-care related disabilities, respectively. The duration of the disease was significantly correlated with the positive symptoms and familial-social disabilities. CONCLUSION: The current study described the high prevalence of psychosocial disabilities in patients with schizophrenia and may have implications for public health interventions.

A case report of T cell prolymphocytic leukemia and Kaposi sarcoma and a review of T cell prolymphocytic leukemia.

T cell prolymphocytic leukemia (T-PLL) is a rare mature T cell lymphoproliferative disease. It has been associated with an aggressive course, a poor response to conventional chemotherapy and a short median survival. Here we present a rare case of concurrent T-PLL and Kaposi sarcoma who achieved a complete hematologic and cytogenetic remission after a very short course of treatment with alemtuzumab. A review of T-PLL was done. In this review, clinical features, laboratory features and current therapeutic strategies of T-PLL are presented.
