Present status of undergraduate urological education in Turkey: is standardization necessary?

23 medical faculties exist in Turkey at the moment and 2 others are being established. Considering that all these faculties run their own programs independently, different education systems might effect the standard of doctors and health care. All of the new graduates in this country face a centralized examination for postgraduate posts in teaching hospitals or start an obligatory service under the authority of the Ministry of Health and Social Welfare. This necessitates standardization in medical education to provide equal facilities and opportunities to all young doctors. Questionnaires, replied to by the urology departments of medical faculties, reflect a wide range of teaching periods in urology with a broad spectrum of topics. Under these circumstances it is advisory to agree on both the time period and content of a standard urology program, as well as other subjects, for better health care and equal chances in centralized examinations.     

The peri‐microvascular edema in hippocampal CA1 area in a rat model of sepsis

Encephalopathy is a common complication of sepsis. However, little is known about the morphological changes that occur in the brain during sepsis. In this study, fecal peritonitis was induced in Wistar rats, which had been monitored for 4 h before their brains were removed and samples from the CA1 area taken. In addition to higher blood pressure with a decreasing pattern and a significant drop in rectal temperature, an increased heart rate and marked respiratory failure were observed. The tissue was investigated and compared with corresponding hippocampal samples taken from sham‐operated and not operated control groups. Significantly more peri‐microvascular edema was found in the hippocampal CA1 area in the septic group. The percentages of the peri‐microvascular edema were 158.57 ± 3.6%, 122.84 ± 1.5% and 120.24 ± 1.9% in the fecal peritonitis group, sham‐operated and not operated control groups, respectively. The results may suggest that the edema observed around the microvessels may participate in the pathogenesis of the septic encephalopathy probably by causing in the microvascular permeability characteristics.     

Current approaches in the treatment of bladder cancer and policy in Marmara University Hospital

Bladder cancer is one of the malignancies encountered frequently in urological practice. Since the three main treatment modalities (surgery, chemotherapy and radiotherapy) may be used alone or together, there are many treatment options. In this paper the current approaches in the treatment of bladder tumours are reviewed and the policy in Marmara University Hospital is described.     

Autoimmune chronic active hepatitis in Down''s syndrome

Hashimoto's thyroiditis, autoimmune adrenalitis, pernicious anaemia, and diabetes mellitus are all recognised associations with Down's syndrome. In addition chronic active hepatitis (CAH) resulting from chronic hepatitis B antigenaemia is known to occur in these patients, but an association of autoimmune CAH and Down's syndrome has not previously been described. We report a case in which Down's syndrome was associated with autoimmune CAH, Hashimoto's thyroiditis, and alopecia areata.     

Rapid diagnosis of rotavirus gastroenteritis by a commercial latex agglutination test.

The Rotalex test, a commercial latex agglutination test for rotavirus, was compared with direct electron microscopy (EM) and the Rotazyme test I, a commercial enzyme immunoassay, for detection of rotavirus in stools of children and neonates. For initial stool specimens from 265 children (less than 3 years old) with diarrhea, the Rotalex test had a sensitivity of 81.7% and specificity of 99.5% compared with EM results. Positive and negative predictive values were 98 and 94.9%, respectively. The Rotalex test was slightly more sensitive and specific than the Rotazyme test. When daily stool specimens from patients with rotavirus gastroenteritis were examined, the sensitivity of the Rotalex test varied depending on the time of stool collection relative to the onset of symptoms. Sensitivity was 100 (20/20), 96 (23/24), and 54% (7/13) during 1 to 4, 5 to 7, and 8 to 18 days, respectively, after the onset of symptoms. The sensitivity of the Rotazyme test varied similarly with days from onset. We also examined 214 EM-negative stool specimens from asymptomatic newborns. False positivity by the Rotalex test was only 3.3% (7/214) compared with 4.2% (9/215) for the Rotazyme test. The Rotalex test was as sensitive and specific as EM for detection of rotavirus during the acute stage of illness and much faster and cheaper than EM or the Rotazyme test. The test appears to be suitable for routine use in small hospitals, emergency wards, or even the physician's office for rapid diagnosis of rotavirus gastroenteritis.     

The evaluation of acute kidney injury due to ischemia by urinary neutrophil gelatinase-induced lipocalin (uNGAL) measurement in patients who underwent partial nephrectomy

The effect of renal artery-only or renal artery–vein clamping during partial nephrectomy on short and long-term functional results: Is clamping technique important?

Purpose

To evaluate the effect of artery-only (AO) and artery–vein (AV) clamping during partial nephrectomy (PN) on short- and long-term renal function outcome.

Methods

Medical records of 154 patients in the AO group and 192 patients in the AV group who underwent open and minimally invasive (laparoscopic/robotic) PN between January 2011 and January 2018 were retrospectively assessed. Preoperative patient and tumor-specific characteristics in addition to perioperative factors and renal function outcomes were compared. The change in the estimated glomerular filtration rate (eGFR) from postoperative 1–3 days, 12 and 24 months after surgery was calculated. Acute kidney injury (AKI) was defined a as a?>?25% reduction in eGFR.

Results

There were no statistically significant differences between the clamping techniques in terms of postoperative 1–3 days, 12 and 24 months eGFR change percentage and risk of progression to chronic kidney disease (CKD). No significant difference in short- and long-term renal functions was found between the minimally invasive or open AO and AV clamping subgroups at any time point. In multivariate analysis, the R.E.N.A.L score (AO group p?=?0.026, AV group p?<?0.001) and preoperative eGFR (AO group p?<?0.001, AV group p?=?0.010) were strong predictors of the acute kidney injury in both groups. Older age (AO group p?=?0.045, AV group p?=?0.010) and preoperative eGFR (AO group p?=?0.008, AV group p?=?0.002) were significantly associated with CKD progression at 2-year follow-up in both groups.

Conclusion

AV clamping does not adversely affect postoperative renal function compared to AO clamping. Preoperative patient- and tumor-related factors are more important for renal function regardless of the clamping technique.
