En-bloc pelvic resection with concomitant rectosigmoid colectomy and immediate anastomosis as part of primary cytoreductive surgery for patients with advanced ovarian cancer.

OBJECTIVE: To assess the authors' experiences in en bloc pelvic resection with concomitant rectosigmoid colectomy and primary anastomosis as a part of primary cytoreductive surgery for patients with advanced ovarian cancer. MATERIALS AND METHODS: Atotal of 22 patients with FIGO Stage IIB-IV epithelial ovarian cancer who underwent en bloc pelvic resection with anastomosis were retrospectively reviewed. Data analyses were carried out using SPSS 10.0 and descriptive statistics, Kaplan-Meier survival curves, and Log Rank (Mantel-Cox) test were used for statistical estimations. RESULTS: Median age was 58.8 years. FIGO stage distribution of the patients was; one (4.5%) IIB, three (13.7%) IIC, three (13.7%) IIIA, six (27.3%) IIIB, and nine (40.9%) IIIC. Median peritoneal cancer index (PCI) was 8 (range 5-22) and optimal cytoreduction was achieved in 18 patients (81.8%) of whom 13 (59.1%) had no macroscopic residual disease (complete cytoreduction). There was no perioperative mortality. A total of nine complications occurred in seven (31.8%) patients. Anastomotic leakage was observed in one (4.5%) patient. There was no re-laparotomy. Mean follow-up time was 60 months. There were 15 (68.2%) recurrences of which 12 (80%) presented in extra-pelvic localizations. Mean disease-free survival (DFS) and overall survival (OVS) were estimated as 43.6 and 50.5 months, respectively. Patients with complete cytoreduction had a better DFS (p = 0.006) and OVS (p = 0.003) than those with incomplete cytoreduction. CONCLUSION: En bloc pelvic resection, as a part of surgical cytoreduction, seems to be a safe and effective procedure in many patients with advanced ovarian cancer if required. Despite relatively high general complication rate, anastomosis-related morbidity of this procedure is low as 0.8%. Nevertheless, surgical plan and perioperative care should be personalized according to medical and surgical conditions of the patient.

The evaluation of morphology of renal pelvicalyceal system's and infundibulopelvic anatomy of kidney's lower pole in post-mortem series.

BACKGROUND: Urinary system stones are frequently encountered in the community. Together with technological developments, introduction of new treatment procedures such as extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy and retrograde intrarenal surgery has further reduced morbidity, mortality and hospitalisation time of patients. In order to maximise success and to reduce complications of these procedures, it is necessary to evaluate anatomy and morphological differences of kidney collector system before the procedure. This study was conducted for the purpose of determining the morphology of the kidney collector system and the negative anatomic factors of the lower pole in autopsy cases performed in our institution. MATERIALS AND METHODS: Eighty two kidney units obtained from 41 autopsy cases conducted in Faculty of Medicine Department of Forensic Medicine, Sivas Cumhuriyet University between September 2017 and September 2018 were included in the study. Percentages were found as 78% for intrarenal pelvis, 13.4% for borderline pelvis, 6.1% for extrarenal pelvis and 2.4% for pelvic nonexistence. When pelvicalyceal anatomy was evaluated, percentages were found as 32.9% for bicalyceal, 26.8% for tricalyceal, 20.7% for multicalyceal, and 19.5% for unclassified calyceality. When it was evaluated according to opening of calyces into the renal pelvis based on Sampaio classification, percentages were found as 30.5% for AI, 17.1% for type II, 28% for BI, 18.3% for BII, and 6.1% for unevaluated part. Infundibular lengths of kidney's lower pole were detected as under 3 cm in 39% and over 3 cm in 61% of all cases. Infundibulopelvic angles of kidney's lower pole were measured as under 70o in 42.7% and over 70o in 57.3% of all cases. RESULTS: In our study, there was no statistically significant difference between the right and left kidneys in terms of collecting system morphology and lower pole's negative anatomical factors. Only infundibular length which is one of the collecting system morphology and lower pole's negative anatomical factors were statistically shorter in females than males. There was no difference in terms of other parameters. CONCLUSIONS: In conclusion, the findings of this study are largely consistent with the results of similar studies. This reveals that renal collecting system morphology and negative anatomic factors in the lower pole collecting system in human are roughly similar. In clinical practice, pre-treatment computed tomography and, if necessary, magnetic resonance urography evaluation of the lower pole negative anatomic factors may contribute to gain preliminary information about both the clearance of stone fragments especially after shock wave lithotripsy and retrograde intrarenal surgery procedures and perioperative complications proactively.

Cardiac safety profile of pegylated liposomal doxorubicin reaching or exceeding lifetime cumulative doses of 550 mg/m2 in patients with recurrent ovarian and peritoneal cancer.

The objective of this study is to evaluate the cardiac safety of pegylated liposomal doxorubicin (PLD) reaching or exceeding a cumulative dose of 550 mg/m(2) in patients with recurrent ovarian and peritoneal cancer. A total of 14 patients (11 ovarian cancer, 3 primary peritoneal cancer) who received PLD in our center between February 2004 and October 2006 met inclusion criteria of the study. PLD was administered at doses of 30 mg/m(2) together with carboplatin or 50 mg/m(2) as a single agent every 3-6 weeks. Left ventricular ejection fraction (LVEF) estimations performed by M Mode ultrasound (General Electric Vivid-3, Milwaukee, Wisconsin) and clinical cardiac status were used to detect PLD-related cardiotoxicity. The median cumulative dose of PLD was 685.5 mg/m(2) (range 552-1015 mg/m(2)) and the median number of PLD courses was 9.5 (range 7-17). One patient had also been previously treated with conventional doxorubicin. LVEF scans were obtained on 10 of the 14 patients at the beginning of the therapy and on all patients at the end of therapy. No clinical evidence (symptoms or physical findings) of cardiac dysfunction had been observed in these patients either during active treatment or follow-up period. Despite small number of patients and lack of control group, our study suggests that the cumulative doses in excess of 550 mg/m(2) of PLD seem to not carry a significant risk of cardiomyopathy as judged by LVEF and clinical follow-up.

Performance of emergency medicine residents in the interpretation of radiographs in patients with trauma.

BACKGROUND: Radiographs are vital diagnostic tools that complement physical examination in trauma patients. A study was undertaken to assess the performance of residents in emergency medicine in the interpretation of trauma radiographs. METHODS: 348 radiographs of 100 trauma patients admitted between 1 March and 1 May 2007 were evaluated prospectively. These consisted of 93 cervical spine (C-spine) radiographs, 98 chest radiographs, 94 radiographs of the pelvis and 63 computed tomographic (CT) scans. All radiological material was evaluated separately by five emergency medicine residents and a radiology resident who had completed the first 3 years of training. The same radiographs were then evaluated by a radiologist whose opinion was considered to be the gold standard. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. RESULTS: The mean (SE) age of the patients was 29 (2) years (range 2-79). There were no statistically significant differences in terms of pathology detection between the emergency medicine residents and the radiologist. The agreement between the emergency medicine residents and the radiology resident was excellent for radiographs of the pelvis and the lung (kappa (kappa) = 0.928 and 0.863, respectively; p<0.001) and good for C-spine radiographs and CT scans (kappa = 0.789 and 0.773, respectively; p<0.001). CONCLUSIONS: Accurate interpretation of radiographs by emergency medicine residents who perform the initial radiological and therapeutic interventions on trauma patients is of vital importance. The performance of our residents was found to be satisfactory in this regard.

Treatment of detrusor sphincter dyssynergia with baclofen and doxazosin.

Detrusor sphincter dyssynergia (DSD) is an involuntary contraction of the external urethral sphincter during detrusor contraction. A high proportion of patients needing repeat surgery and long term failure have both been described in the literature. In the present study, we evaluated clinical characteristics, underlying disorders and outcomes of conservative medical treatment in 21 female patients. Two patients were newly diagnosed multiple sclerosis. Urodynamic studies were performed in all symptomatic patients, and consisted of measurement of post-micturition residuals, urethral pressure profilometry and EMG cystometry according to the criteria of the International Continence Society. All patients were treated with baclofen 15 mg/day and doxazosin 4 mg/day. Seven patients received tolterodine 4 mg/day in addition to baclofen and doxazocin because they had detrusor hyperreflexia (DH). In conclusion, treatment with either combined baclofen and doxazosin or anticholinergic agent tolterodine appeared to be effective. In addition, it should be kept in mind that DSD could be the first sign to any neurologic diseases.

Isolated renal and retroperitoneal hydatid cysts: a report of 23 cases.

Isolated extrarenal retroperitoneal and renal echinococcal cysts are rare manifestations of hydatid disease. We report 23 cases of renal and other retroperitoneal hydatid cysts diagnosed and treated in our clinic. Flank pain, abdominal mass and non-specific symptoms such as nausea and vomiting were the major symptoms. Indirect haemagglutination test was positive in 18 cases and eosinophilia in four cases. Among imaging studies computerized tomography was the most valuable diagnostic examination. A high index of suspicion is needed for preoperative diagnosis of hydatid disease of kidney and retroperitoneum.

Recurrent mutations in the vasopressin-neurophysin II gene cause autosomal dominant neurohypophyseal diabetes insipidus.

We examined the nucleotide sequence of the arginine vasopressin-neurophysin II gene in three kindreds with autosomal dominant neurohypophyseal diabetes insipidus. Each of the three different mutations identified represents a recurrence of a mutation previously described to cause this disease. These mutations are all transitions (C1761-->T, G1859-->A, and G279-->A) that encode amino acid substitutions Pro24-->Leu, Gly57-->Ser (both in neurophysin II), and Ala-->Thr (in the last amino acid at the C-terminus of the signal peptide). The presence of these mutations in genomic DNA was confirmed by alterations in restriction endonuclease recognition sites. A linkage map of distal chromosome 20 was constructed. To examine the possibility that these apparent recurrent mutations arose independently rather than by an ancestral founder mutation, we analyzed family origins, two polymorphic markers on chromosome 20 in close proximity with this gene (the oxytocin/XbaI restriction fragment length polymorphism and the D20S57 polymorphic CA repeat microsatellite), and/or the occurrence of a de novo mutation in our three families and in four additional families previously reported. Our results suggest that one of our families may share an ancestral founder mutation with one previously reported family, but that in the remainder of the families with identical mutations, these mutations probably arose independently.

Heterogeneity in clinical manifestation of autosomal dominant neurohypophyseal diabetes insipidus caused by a mutation encoding Ala-1-->Val in the signal peptide of the arginine vasopressin/neurophysin II/copeptin precursor.

Autosomal dominant neurohypophyseal diabetes insipidus (ADNDI) is a familial form of diabetes insipidus due to progressive vasopressin deficiency with onset typically at 1-6 yr of age. Affected individuals demonstrate specific degeneration of the vasopressinergic magnocellular neurons in the hypothalamic supraoptic and paraventricular nuclei and loss of the posterior pituitary bright spot on magnetic resonance imaging. The genetic locus of ADNDI is the arginine vasopressin-neurophysin II (AVP-NPII) gene. Mutations that cause ADNDI have been found to occur both within the signal peptide of the prepro-AVP-NPII precursor and within the coding sequence for neurophysin II, but not within the coding sequence for AVP itself. We evaluated the AVP-NPII genes in two independent families with ADNDI and identified a mutation (C280-->T) in the coding sequence for the signal peptide of the prepro-AVP-NPII precursor in both families. This mutation encodes an Ala-->Val substitution at the C-terminus of the signal peptide (-1 amino acid). This mutation predicts the complete inability of signal peptidase to cleave the signal peptide from the preproprecursor and supports the hypothesis that the progressive neural degeneration that underlies ADNDI is caused by accumulation of malprocessed precursor. However, considerable heterogeneity in the age of onset (1-28 yr of age) and the severity of diabetes insipidus among affected members of these two families suggests that additional factors modulate the rate and extent of progression of the neurodegeneration that results from this one specific ADNDI mutation.

Retrosternal density: pulmonary underdevelopment or accessory hemidiaphragm.

Vertical retrosternal density paralleling the sternum, with haziness of a hemithorax on chest roentgenogram, often challenges the clinical acumen of pediatricians, chest physicians, and pediatric radiologists alike. Its presence has been historically linked to either pulmonary underdevelopment and/or accessory hemidiaphragm. The surgical and radiological pediatric literature has long debated this topic, but unfortunately, it has not received much attention in the general pediatric or in pediatric pulmonology literature. The similar radiologic appearance of these two entities can cause confusion both in diagnostic and the therapeutic approach. Many authors advocate an invasive modality, including thoracotomy, as the only definitive way to differentiate between them. We present two similar cases with retrosternal densities, review the pertinent literature, and propose a rational approach to diagnosis and treatment.

Megalourethra associated with prune-belly syndrome.

A 14-day-old male infant with megalourethra is presented because of the rarity of the anomaly and its association with prune-belly syndrome. The lax, wrinkled appearance of the abdomen, bilateral cryptorchidism and severe dilatation of the urinary system are features included in the classic triad of the prune-belly syndrome. Our patient had the scaphoid variety of megalourethra since the penis appeared elongated and floppy in the fusiform form.

Multiple primary tumours of the urogenital system: our cases and a review of the literature.

We had 6 genitourinary tumour patients with other primary tumours in a 147 genitourinary tumour patient group. Two of these tumours developed synchronously while the others were metachronous, and two of them developed in the genitourinary system. It is clear that cancer patients have a higher risk of a second cancer than the general population. Second cancers may be detected in long-term follow-up of cancer patients, or may be caused by the aetiologic factor(s) with pleiotropic effects, or may develop because of the therapies for the first cancer.

K-RAS mutation in transitional cell carcinoma of urinary bladder.

In the present study it was aimed to investigate the frequency of K-RAS mutation in the human bladder transitional cell carcinoma. For this purpose, tissue specimens obtained from the patients with bladder tumors. Genomic DNAs were isolated and then PCR-SSCP analysis of K-RAS gene were performed. A heterozygous deleted mutation was detected in K-RAS oncogene (exon 2) in agarose gel electrophoresis in one patient and point or substitution mutations are detected using single strand conformational polymorphism (SSCP) in other different patients with bladder cancer (4/14). In conclusion, the frequency of K-RAS mutation is not rare and the role of this mutation in oncogenesis and in infiltration of the urinary bladder wall needs to be confirmed in a larger study.

Adenomatoid tumors of testis and epididymis: a report of two cases.

Adenomatoid tumors are rare benign tumors of female and male genital tracts. In this paper, we reported an epididymal and a testicular adenomatoid tumor in two patients presented with enlarged intrascrotal mass.

[Bacteria isolated from urine and renal tissue samples and their relation to renal histology]. / Idrarda ve böbrek doku örneklerinde üretilen bakteriler ve böbrekteki histolojik degisiklikler ile iliskileri.

The bacteria from the urine and renal biopsy specimens of 40 patients undergoing renal surgery were isolated and their relations with renal histology investigated. The urine cultures were positive in 14 patients, the same organisms being isolated from the renal tissue in 7 cases. In 6 patients with negative urine cultures, bacteria were isolated from renal tissues. Of the 28 cases pathologically diagnosed as chronic pyelonephritis, bacteria were isolated from the renal tissue in 13 cases, the urine cultures being positive in only 11 cases. E. coli was the most commonly encountered bacteria in both the urine and renal tissues.

Contractile responses of urinary bladder in an experimental model of chronic renal failure.

Chronic kidney disease is a public health problem with increasing prevalence caused by diabetes, hypertension and glomerulonephritis. Number of publications investigate the lower urinary tract dysfunction due to CKD is limited. There is a high incidence of bladder dysfunction of different degrees in patients with renal failure. Mechanism of the lower urinary tract dysfunction in these patients is not well known. In this study, we aimed to investigate the effects of CKD on detrusor function in a rat model of CKD. In our study, 20 Wistar Albino rats have been divided into two groups as CKD and control groups. To the experiment group, left partial nephrectomy and right nephrectomy have been applied. CKD confirmation has done with the BUN and creatinin values from the blood of the rats. The bladder strips were prepared from the CKD and control groups and its contractile responses were evaluated in-vitro. There wasn't a considerable difference with the contractile responses caused by carbachol, KCL. There was a considerable increase in the contractile responses caused by ATP, ADP and electrical field stimulation on the behalf of the CKD group. The present study demonstrated that isolated DSM of CKD group showed significantly increased contraction responses to purinergic agonists ADP, ATP and atropine resistant component in electrical field stimulation-induced contractions as compared to those of the control group. Bladder overactivity and reduced bladder volume in CKD patients might be due to the change in purinergic system.

Effects of antituberculosis treatment on self assessment, perceptual analysis and acoustic analysis of voice quality in laryngeal tuberculosis patients.

OBJECTIVES: To evaluate the effects of antituberculosis treatment on the voice quality of laryngeal tuberculosis patients, measured by patient self-assessment, perceptual analysis and acoustic analysis. MATERIALS AND METHODS: A total of 14 laryngeal tuberculosis patients were enrolled. Laryngeal tuberculosis was established either by biopsy and histopathological examination or by rapid regression of the laryngeal lesions after antituberculosis medication. Before and after treatment, all patients were evaluated perceptually (on a scale of zero to three), and 12 assessed their own voices using the voice handicap index-10 scale. Acoustic analysis was performed to allow objective evaluation. RESULTS: Patients' ages ranged from 21 to 72 years (mean, 41). The male to female ratio was 12:2. Eight patients (57 per cent) had tuberculous involvement of the epiglottis, four (28 per cent) had involvement of the aryepiglottic fold and eight (57 per cent) had involvement of the false vocal folds. The glottis was the less commonly involved part of the larynx, including true vocal folds (28 per cent, n = 4) and posterior commissure (14 per cent, n = 2). Perceptual evaluation, on a scale of zero to three, gave the patients a median score of six; after commencement of treatment, the median score decreased to two. The mean voice handicap index-10 score decreased from 24 to 12 after treatment. An obvious improvement in acoustic analytical parameters was also found following treatment. CONCLUSIONS: Antituberculosis treatment clearly improved the voice outcomes of laryngeal tuberculosis patients, according to self-assessment, perceptual analysis and acoustic analysis.

Efficacy of combined anticholinergic treatment and behavioral modification as a first line treatment for nonneurogenic and nonanatomical voiding dysfunction in children: a randomized controlled trial.

PURPOSE: This randomized blinded clinical study was designed to compare the efficacy of tolterodine treatment combined with behavioral modification, behavioral modification alone and behavioral modification plus placebo in children with nonneurogenic, nonanatomical voiding dysfunction. MATERIALS AND METHODS: A total of 72 children meeting inclusion criteria were randomly allocated to 1 of 3 groups. One group received tolterodine (1 mg twice daily) along with behavioral modification, 1 received behavioral modification only and 1 received placebo with behavioral modification. A dysfunctional voiding scoring system questionnaire was completed for all patients at the beginning of the study, and at 1 and 3 months of treatment. RESULTS: A total of 71 patients were evaluated. The groups did not differ with respect to age, gender and symptom score before study enrollment (p >0.05). Repeated calculations of symptom scores at 1 month of the treatment revealed a significant decrease in symptoms in all 3 groups, with a significant decrease in patients receiving tolterodine. In addition, at month 3 the symptom score of the tolterodine group was significantly lower compared to month 1, while scores remained steady in the behavioral modification and behavioral modification plus placebo groups. CONCLUSIONS: Tolterodine combined with behavioral modification for voiding dysfunction in children without neurological or anatomical abnormality can be recommended as a first line treatment before invasive evaluation.
