Do Prostatic Infarction,Prostatic Inflammation and Prostate Morphology Play a Role in Acute Urinary Retention?

OBJECTIVE: To investigate whether there is a role of prostatic infarction, prostatic inflammation and prostate morphology in acute urinary retention (AUR) etiology. METHODS: Ninety-eight consecutive male patients who were admitted to our clinic with either AUR or lower urinary tract symptoms (LUTS) were involved in the study. Patient age ranged from 43 to 88 years (median age 70). Group 1 consisted of 53 (54%) patients with AUR, and Group 2 consisted of 45 (46%) patients with LUTS. In Group 1 and Group 2, 58.4% (n:31) and 62.2% (n:28) of the patients underwent transurethral prostate resection, 41.6% (n:22) and 37.8% (n:17) of the patients underwent suprapubic transvesical prostatectomy, respectively. Each patient was asked about the factors: smoking habits, taking previous general anesthesia and preexisting cardiovascular disease such as hypertention and atherosclerotic coronary vascular disease which may lead to AUR via prostatic infarct. Prostatic infarction, prostatic inflammation and prostatic morphology were examined in the patients' specimen. RESULTS: Mean age, median serum prostate-specific antigen (PSA) level, and prostatic inflammation ratio were significantly higher in Group 1. There were not significant differences between the groups regarding prostate volume, prostatic infarction ratio and a type of prostatic morphology. In the present study, except for taking previous general anesthesia and preexisting cardiovascular disease, only prostatic inflammation was found important contributory factor on AUR. AUR risk was 3.03 times higher in the patients with prostatic inflammation (95%CI 1.28-7.15) (p = 0.01). CONCLUSIONS: No significant effect of prostatic infarction was found on occurrence of AUR which was more frequent in elderly patients. Prostatic inflammation may have an important risk factor in AUR etiology. Additionally, serum PSA levels were higher in AUR group. No association was found between a type of prostatic morphology and AUR.     

Granulocyte Macrophage-Colony Stimulating Factor Improves Impaired Anastomotic Wound Healing in Rats Treated with Intraperitoneal Mitomycin-C

Purpose Intraperitoneal chemotherapy (IPCT) delivers higher local concentrations of cytotoxic drugs than intravenous (IV) chemotherapy, but it can adversely affect the healing of intestinal anastomoses if given in the early postoperative period. Intestinal anastomotic leakage is a serious surgical complication. Experimental and clinical studies have shown that the local administration of granulocyte macrophage-colony stimulating factor (GM-CSF) improves would healing. Therefore, we evaluated the effects of locally applied GM-CSF on anastomotic wound healing in rats treated with intraperitoneal mitomycin-C immediately after surgery.Methods We performed colon anastomoses in albino rats, which were then divided into three treatment groups. Group A was a control group that received no treatment, Group B was given intraperitoneal mitomycin-C postoperatively, and Group C was given intraperitoneal mitomycin-C with a local injection of GM-CSF postoperatively. We measured bursting pressures and hydroxyproline content, and histologically examined the resected anastomoses on postoperative day (POD) 3.Results Anastomotic healing was impaired after intraperitoneal mitomycin-C, but this was overcome by the injection of GM-CSF into the perianastomotic area.Conclusion Local GM-CSF administration counteracts the detrimental effects of intraperitoneal mitomycin-C treatment on intestinal anastomoses in rats.     

Sarcoidosis Presenting as Cold Thyroid Nodules: Report of Two Cases

Sarcoidosis is a systemic disease characterized by noncaseating granulomas. Thyroid involvement is rare in sarcoidosis. In this paper, two sarcoidosis patients who demonstrated cold thyroid nodules are presented. A 42-year-old woman presented with multinodular goiter and was diagnosed as having sarcoidosis when noncaseating granulomas were observed during the pathological examination of the thyroidectomy specimen. Enlarged mediastinal lymph nodes were observed in the routine preoperative chest X-ray in another 53-year-old woman, while she was being prepared to undergo a thyroidectomy. The pathological examination of the thyroid specimens showed noncaseating granulomas in both patients, and the diagnosis was confirmed by either hepatic biopsy or chest X-ray findings. In conclusion, thyroid involvement should be suspected in sarcoidosis patients who present with cold nodules in the thyroid. Furthermore, if noncaseating granulomas are observed in thyroid specimens after a thyroidectomy in an otherwise healthy person, the patient should be evaluated further for sarcoidosis.     

A case of lupus erythematosus profundus with unusual manifestations

We describe a 16-year old female with lupus erythematosus panniculitis with unusual manifestations. She had noted to have developed erythematous nodules and plaques in the right axilla and inguinal region at the age of one year. These lesions resolved gradually with scar formation. However, new lesions were noted at the same locations in the following years. Some of her lesions at the scalp and the left axillary regions developing within the last two years slowly enlarged showing an annular configuration and subsequently resulted in hair loss. The erythematous border of her lesion in the left axilla consisted of two parallel red lines. Histopathological and direct immunofluorescent findings were consistent with lupus erythematosus panniculitis. Similar clinical findings in the same locations were also observed in the mother.     

Surgical management of enoxaparin- and/or warfarin-induced massive retroperitoneal bleeding: report of a case and review of the literature

A 70-year-old man on enoxaparin and warfarin sodium therapy due to pulmonary embolism was admitted for evaluation of a sudden, sharp pain in the left inguinal region. Physical examination revealed a 5 x 10 cm tender mass. Abdominal ultrasound showed a 9 x 9 x 10 cm left retroperitoneal hematoma. INR was 2.1, and anticoagulation therapy was discontinued. A regimen of supportive therapy (vitamin K, fresh frozen plasma and blood transfusion) was started, but the hemorrhage continued to enlarge, up to 9 x 10 x 20 cm, and the patient experienced a significant deterioration in his overall status. He underwent an urgent laparotomy and the hematoma was evacuated. A retroperitoneal abscess developed during the postoperative period which was drained percutaneously. He was discharged on postoperative day 33 with no further complaints. This case demonstrates the importance of surgical therapy in the treatment of spontaneous retroperitoneal hemorrhage caused by anticoagulant therapy.     

Comparison of effects of dry versus wet swallowing on Eustachian tube function via a nine-step inflation/deflation test

The aim of the present study is to evaluate the effect of swallowing type (dry versus wet) on the outcome of a nine-step inflation/deflation tympanometric Eustachian tube function (ETF) test in healthy adults. Fourteen normal healthy volunteers, between 19 and 28 years of age, were included in the study. The nine-step test was performed in two different test procedures: (1) test with dry swallows (dry test procedure) and (2) test with liquid swallows (wet test procedure). If the equilibration of middle-ear (ME) pressure was successful in all the steps of the nine-step test, ETF was considered 'Good'. Otherwise, the test was considered 'Poor', and the test was repeated at a second session. In the dry test procedure, ETF was 'Good' in 21 ears at the first session and in 24 ears after the second session (p > 0.05). However, in the wet test procedure, ETF was 'Good' in 13 ears at the first session and in 21 ears after the second session (p < 0.05). At the first session, ETF was 'Good' in 21 and 13 ears in the dry and wet test procedures, respectively. The difference was statistically significant (p < 0.05). However, after the second session, the overall number of ears with 'Good' tubal function was almost the same in both test procedures (24 ears at dry test procedures versus 21 ears at wet test procedures;p > 0.05). Dry swallowing seems to be more effective for the equilibration of ME pressure. Thus, a single-session dependent evaluation of ETF may be efficient for the dry test procedure of the nine-step test. Swallowing with water may be easier for subjects, but a repetition of the test at a second session may be necessary when the test result is 'Poor'.     

PAX5/IGH rearrangement is a recurrent finding in a subset of aggressive B-NHL with complex chromosomal rearrangements

We present an extensive characterization of 10 B-cell lymphomas with a t(9;14)(p13;q32). The presence of the PAX5/IGH gene rearrangement was demonstrated by fluorescence in situ hybridization (FISH) using a validated probe set, whereas complex karyotypic changes were reassessed by multiplex-FISH (M-FISH). Pathologic and clinical review revealed the presence of this rearrangement in 4 histiocyte-rich, T-cell-rich B-cell lymphomas (HRTR-BCLs) and 2 posttransplantation diffuse large B-cell lymphomas (PTLD-DLBCLs). In contrast to initial observations describing this translocation in lymphoplasmacytic lymphoma (LPL) and LPL-derived large B-cell lymphoma, our data showed a wide morphologic and clinical spectrum associated with the PAX5/IGH rearrangement, pointing to an association between this aberration and a subset of de novo DLBCLs presenting with advanced disease and adverse prognosis. In addition, the recurrent incidence of this rearrangement in both HRTR-BCL (4 cases) and PTLD-DLBCL (2 cases) was previously unrecognized and is intriguing.
