Primary mesenteric liposarcoma of jejunum: presentation like a cystic mass.

This report describes a rare case of intra-abdominal liposarcoma in a 67-year-old woman. The patient presented at Internal Medicine Unit in May 2004, to study of thyroid pathology. The clinical examination was normal, except for the finding of an asymptomatic mass in the abdomen. The patient knew the existence of tumor since time ago, but she confesses to have only occasional discomfort. In the abdominal ultrasonography a solid mass with large cystic component was detected but relation with other organs was not clear. Computed tomography revealed the presence of a mass with solid and cystic components, in contact with small intestine in the left side of abdomen. A complete resection of tumor arising from mesentery of jejunum was performed successfully with end to end anastomosis. The gross specimen was lobulated and measured 8.5 x 7.5 cm. The histopathology analysis showed proliferating lipoblasts with irregular nuclei on a myxoid background, with plexiform vascular pattern, characteristics belongs to myxoid type liposarcoma. The patient is alive and well one year after removal of tumor. The uncommon site and the exceptional cystic morphology of tumor are discussed, and so it must be included the primary mesenteric liposarcoma in the differential diagnosis of intra-abdominal tumors with cystic large areas.

[Metabolic control of diabetes mellitus en relation to the quality of the medical records].

OBJECTIVE: To investigate whether there is a relationship between the quality of the clinical history (CH) in primary care and metabolic control of patients with diabetes (DM). DESIGN: Retrospective and observational. SETTING: 15 health centres in the Segovia Area. PATIENTS: 315 diabetic patients, selected at random from among those with a record of the type of DM, date and outcome of at least one HbA1c and treatment at the time of the most recent HbA1c. RESULTS: The quality of the clinical histories was measured through the mean of recording of the following items in the 13 months previous to the most recent HbA1c: weight and height, peripheral pulses, sensitivity, foot examination, creatinine, proteinuria, microalbuminuria, glucaemia levels, back of eye, ECG, and diet, tobacco and alcohol counselling. Other variables that could condition the HbA1c, chronic pathologies and those related to DM, were gathered too. Of patients treated with diet or oral diabetic drugs, patients with a clinical history of < or = 49% quality had a mean HbA1c of 7.40%, whereas those with CH of > or = 50% quality had an average of 6.94% (0.46 difference; 95% CI, 0.03-0.90; p = 0.038). This drop was not attributable to age, gender, years of evolution or BMI differences. The risk of having an HbA1c > or = 7.5% is double in patients with a CH of < or = 49% quality than in those with CH of > or = 50% quality (OR = 2.06; 95% CI, 1.14-3.72). In insulin-treated patients, no association between CH quality and HbA1c was found. CONCLUSIONS: Follow-up of the recommendations for clinical action is associated with better metabolic control in diabetics treated with diet--oral diabetic drugs. This association was not found in insulin-treated patients.

[Solitary nasal plasmocytoma].

Report of the case of one patient diagnosed of a nasal extramedullary solitary plasmacytoma, starting as an suppurated panophtalmia. Biopsy of the mass inside the nose led to diagnosis. Comments about the difficulties of histopathological differential diagnosis, underlying the need to rule out any other systemic process (multiple myeloma). The subject was treated with inductive chemotherapy and radiotherapy, being free of the illness after 4 years follow up.

[Undifferentiated small cell tumor of the thoracopulmonary region].

The group of rounded small-cell tumors include different neoplasias involving different therapies; we can name neuroblastoma, Ewing' sarcoma, embrionary rhabdomyosarcoma, lymphoma and other pathology such as Askin's tumor or small cell tumor of the thorax area. Based on microscopic and immunohistochemistry findings, it is suggested that it originates from the neural crest or pluri-potential cells from the neuroectodermy. This has a very aggressive behaviour and is usually resistant to oncologic therapies.

[Thymomas].

Thymomas are non-frequent neoplasias which are interesting because of their special association with the immune system pathology; although the pathogenic relationship has yet to be confirmed. A literature review is carried out on clinical aspects, prognosis and treatment, basically chemotherapy in advanced cases. Although they are classically categorized as benign, they are nevertheless considerably aggressive and maintain a low response to most active oncology treatment.

[Analysis of patients violence in primary care].

OBJECTIVE: Main aim: to determine the frequency of violence in primary care. Secondary aims: to analyse its causes, consequences and connection with professional burnout and reduced motivation. DESIGN: Transversal, descriptive study. SETTING: Primary care. PARTICIPANTS: 68 primary care doctors from 4 districts in the province of Jaén (350, 19%). MAIN MEASUREMENTS: Self-administered questionnaire with an ad hoc design, sent out by mail and including personal and job details and doctors' views on the causes and consequences of burnout and violence, and the attitudes of the Andalusian Health Service (SAS) and professional bodies (overall reliability, Cronbach's alpha =.7898). RESULTS: 58% had suffered aggression (85% verbal abuse, 67.5% threats, 12.5% physical aggression). Being attacked was linked with attributing the responsibility to the patients (odds ratio [OR]=7.6, 95% confidence interval [CI], 2.5-23), with doing extra shifts (OR=6.3; 95% CI, 1.2-33), rigidity (OR=3.5; 95% CI, 1.2-10.7), inadequate handling of emotive situations (OR=3.2; 95% CI, 1.1-9.2,) and incompetence (OR=5.2; 95% CI, 1.6-17). Violence scored the lowest as cause of burnout and was linked to the job being less rewarding (OR=2.9; 95% CI, 1.0-7.8). It was linked to irritation with the SAS (OR=2.8; 95% CI, 1.0-7.5) and fear of reduced motivation (OR=2.8; 95% CI, 1.0-7.5), with this latter being linked to loss of social prestige (P<.01), feeling low self-esteem (P<.01), and depression (P<.01). CONCLUSIONS: Violence is more common than in the figures given by the International Labour Organisation. It is associated with distrust, lack of communication in health care delivery and incompetence. It is the cause of burnout that is least appreciated and it is linked to the job being less rewarding and to greater fear of reduced motivation.
