OBJECTIVE: The purpose of this trial was to determine the spectrum of diseases with fever of unknown origin (FUO) in Turkey. METHODS: A prospective multicenter study of 154 patients with FUO in twelve Turkish tertiary-care hospitals was conducted. RESULTS: The mean age of the patients was 42+/-17 years (range 17-75). Fifty-three (34.4%) had infectious diseases (ID), 47 (30.5%) had non-infectious inflammatory diseases (NIID), 22 (14.3%) had malignant diseases (MD), and eight (5.2%) had miscellaneous diseases (Mi). In 24 (15.6%) of the cases, the reason for high fever could not be determined despite intensive efforts. The most common ID etiologies were tuberculosis (13.6%) and cytomegalovirus (CMV) infection (3.2%). Adult Still's disease was the most common NIID (13.6%) and hematological malignancy was the most common MD (7.8%). In patients with NIID, the mean duration of reaching a definite diagnosis (37+/-23 days) was significantly longer compared to the patients with ID (25+/-12 days) (p=0.007). In patients with MD, the mean duration of fever (51+/-35 days) was longer compared to patients with ID (37+/-38 days) (p=0.052). CONCLUSIONS: Although infection remains the most common cause of FUO, with the highest percentage for tuberculosis, non-infectious etiologies seem to have increased when compared with previous studies.  相似文献

PURPOSE: Different methods for managing pilonidal sinus have been described in the literature. Our purpose was to evaluate the influence of postoperative drainage in Limberg flaps. METHODS: Forty patients with pilonidal sinus undergoing radical excision and reconstruction with Limberg flap between 1994 and 1996 were evaluated prospectively. After patients were assigned randomly to the two groups, the effects of drains were studied statistically in terms of wound complications, hospital stay, and recurrence rate. RESULTS: Except for two minor transient wound dehiscences, in all cases primary healing was achieved. Early wound complication rate was 7.5 percent and recurrence rate was 2.5 percent for both groups. There was no significant difference between the groups in early wound complications (P>0.05). The length of hospital stay was significantly longer in the drainage group (P<0.001). CONCLUSION: We conclude that Limberg flaps with no drains in place will result in shorter hospital stays without deleteriously affecting the surgical results of wide excision and primary closure with well-vascularized tissue.  相似文献

Approximately, one fourth of women have leiomyomas. Leiomyomas are benign tumors that originated from smooth muscle cells. Estrogen is claimed to relate as a cause but exact mechanism has not fully understood. In this study, 95 leiomyoma cases that have been diagnosed by our department in years between 2010 and 2012 were examined. Age ranges of patients, sizes, locations, and numbers of leiomyomas were identified. Immunohistochemically ER (estrogen), PR (progesterone), and Gross cystic disease fluid protein-15 stains were performed to the paraffin blocks and their percentages of staining were noted. Statistically, submucosal and intramural locations were significantly related to ER and PR (p < 0,001). There were significant relationship between ER and PR in 30–50 years age group (p < 0,001). There were significant relationship between ER, PR and locations (p < 0,001), numbers (p < 0,001), sizes of leiomyomas (below 5 cm; p < 0,001), (between 5 and 10 cm; p = 0,037), larger than 10 cm; p = 0,002). Consequently, relationship between leiomyoma and ER, PR were revealed in this study. Also, relationship between leiomyoma locations and patient ages were identified statistically. There was no immunoreactivity with GCDFP-15 in leiomyomas.  相似文献
