Tumor recurrence in prostatic urethra following simultaneous resection of bladder tumor and prostate

A comparative retrospective study was performed on 100 patients who had undergone transurethral resection of a superficial bladder tumor (Ta-Tl) with no associated carcinoma in situ (group 1) and 100 patients who had undergone simultaneous transurethral resection of a superficial bladder tumor (Ta-Tl), with no associated carcinoma in situ, and benign prostatic hyperplasia (group II). Evaluation of the recurrences of prostatic urethral tumors in both groups showed that they appeared in 10 patients (12 recurrences) in group I and 10 patients (14 recurrences) in group II (p = not significant). These data enabled us to rule out the influence of simultaneous transurethral resection in cases of recurrences of prostatic urethral tumors.     

Aspects of imported malaria at a district general hospital in non-endemic Kuwait,Arabian Gulf

There is no indigenous mosquito-borne transmission of malaria in Kuwait. However, in a five year period at a district general hospital, the number of laboratory-diagnosed cases of malaria increased annually from 25 to 84, a rise of 336%. Except for two induced infections, all were imported, mainly from the Indian subcontinent. Plasmodium vivax was responsible for 87.29% of the cases; P. falciparum (12.05%), a mixed infection of P. vivax and P. falciparum (0.33%) and a case of P. ovale (0.33%) were also identified. Rapid preparation of acetone-fixed, Giemsa-stained thick blood films, a heightened awareness of the infection, examination of multiple samples of blood from patients and the general resurgence of malaria in endemic areas were some of the factors responsible for the high number of cases diagnosed. Most patients were young males and presented with clinical malaria due to P. vivax between May and October each year, an apparent seasonal peak. However, many were already resident in the country for a variable period. Patients with P. falciparum though, presented clinically within two weeks of arrival in the country. Parasite densities were calculated to monitor the progress of treatment and identify quickly any possible chloroquine-resistant P. falciparum strains. A policy of active prophylaxis is suggested to stem the tide of imported malaria.Corresponding author.     

Conventional viral cultures and shell vial assay for diagnosis of apparently culture-negativeCoxiella burnetii endocarditis

A patient with culture-negative endocarditis was diagnosed with Q fever endocarditis based on the results of serological tests and positive leukocyte cultures obtained using conventional viral cultures and the shell vial technique. This case report suggests that isolation ofCoxiella burnetii from blood may allow better diagnostic and therapeutical evaluation of patients with Q fever endocarditis. The use of both conventional and shell vial viral cultures is recommended for the isolation ofCoxiella burnetii from the blood of patients with apparently culture-negative endocarditis.     

Multidimensional approach to the differences between muscular and articular temporomandibular patients: coping, distress, and pain characteristics.

OBJECTIVE: This study analyzes the differences in psychological variables and symptomatology between temporomandibular disorder diagnosis subgroups. STUDY DESIGN: The sample included 114 temporomandibular disorder patients that were evaluated in coping, distress, and temporomandibular characteristics. Diagnostic muscular (n = 58) and articular (n = 56) subgroups were compared in these variables through a MANCOVA. RESULTS: Muscular patients show a higher level of general distress, specifically in the anxiety and somatization subscales and a more active coping style, with a tendency of a minor use of humor and a higher number of parafunctional habits, specifically, biting nails, hangnails, and lips. CONCLUSION: We discuss the differences found in order to design the targets of the psychological intervention of temporomandibular patients.     

Locally aggressive central odontogenic fibroma associated to an inflammatory cyst: a clinical, histological and immunohistochemical study

The case describes a 38-year-old woman presenting a multilocular radiolucency affecting the entire right half of the lower jaw, with an unerupted third molar displaced to the region of the coronoid process. The histological study showed the presence of fibroblasts, focally with pleomorphic nuclei, dense collagen and an odontogenic epithelium with dystrophic calcifications. A cyst with an important inflammatory infiltrate was, moreover, observed.
