Comparison of the Exposure Obtained by Endoscope and Microscope in the Extended Trans-Sphenoidal Approach

Objective: Trans-sphenoidal surgery is often combined with other approaches for the treatment of middle cranial base tumors. By combining a maxillotomy with trans-sphenoidal approach, significantly wider exposure to these regions is gained. However, endoscope-assisted techniques have also been used for sellar and parasellar and upper clival regions. Methods: An extended trans-sphenoidal approach was performed on 10 cadaver heads using the operating microscope and was repeated with a 0-degree endoscope. The mean horizontal and vertical distances were measured and pictured for each technique, and both distances were compared using a parametric paired Student's t-test. Results: The mean horizontal distances in the 10 specimens were 19.5 ± 1.8 mm by microscope and 27.5 ± 2.2 mm by endoscope, and the mean vertical distances were 25.8 ± 1.9 mm by the microscope and 34.5 ± 3.5 mm by the endoscope. Conclusion: The aim of this study was to quantify the amount of exposure obtained with an extended trans-sphenoidal approach and to compare both endoscopic and microscopic techniques. Using the endoscope in conjunction with the operating microscope may provide additional exposure and better access in skull base surgery.     

Preliminary findings for preemptive analgesia with inhaled morphine: efficacy in septoplasty and septorhinoplasty cases.

OBJECTIVE: The aim of this study was to assess the efficacy of inhaled morphine for preemptive analgesia in patients who undergo septoplasty or septorhinoplasty. STUDY PLAN AND METHODS: Eighty ASA I-II patients scheduled for septoplasty or septorhinoplasty were recruited and randomly divided into 2 groups that received different treatments 10 minutes prior to induction. The preemptive analgesia group (Group P, n = 40) received 65 mug kg(-1) morphine sulphate (a 3-mL volume) via an oral nebulizer, and the control group (Group C, n = 40) received 3 mL 0.9% sodium chloride (physiological saline) via the same type of nebulizer. Blood pressure, oxygen saturation, heart rate, time to first requirement for analgesia, and occurrence of nausea/vomiting were recorded. RESULTS: There were no significant differences between Groups P and C with respect to age, body weight, sex distribution, or duration of surgery. There was also no significant difference between the group frequencies of postoperative nausea/vomiting. The time to first requirement for analgesia was significantly longer in Group P than Group C. CONCLUSION: The results of this preliminary study suggest that a single dose of inhaled morphine administered preemptively prior to septoplasty or septorhinoplasty provides effective postoperative analgesia. EBM rating: B-3b.     

Metastasis of Prostate Adenocarcinoma to Testis

Metastatic carcinoma to the testis is very rare. Metastasis of prostate adenocarcinoma to testis was detected incidentally after bilateral orchiectomy for hormonal management of metastatic prostate carcinoma. The metastatic lesion was not identified in physical examination or in macroscopic dissection of the testis after surgery. Microscopy revealed an adenocarcinoma which, given the history of the patient and a positive immunohistochemical stain for PSA, was identified as metastatic prostatic adenocarcinoma.     

Evaluation of the harmonized alert sensing technology device for hemodynamic monitoring in chronic hemodialysis patients

The Harmonized Alert Sensing Technology (HASTE) device was developed to overcome the primary shortcomings of interval based noninvasive blood pressure (BP) monitoring. This study was conducted to assess the reliability of the HASTE system compared with standard cuff BP values in patients on hemodialysis. A total of 1,370 HASTE measurements were compared with oscillometric standard cuff systolic BP values in 42 sessions of 15 patients on hemodialysis. The average discrepancy between the HASTE and cuff systolic BP was 1.41 +/- 16.90 mm Hg. Compared with cuff measurements, 31% of systolic BP fell within a range of 5 mm Hg difference, 57% of systolic BP fell within 10 mm Hg, and 73% of systolic BP fell within a 15 mm Hg band. According to British Hypertension Society standards or Association for the Advancement of Medical Instrumentation criteria, the current HASTE method did not perform well. Technology to provide noninvasive hemodynamic monitoring is, however, in its developmental stage. The effort at continuous systolic pressure monitoring using existing, readily available, and frequently used techniques is exciting. Although the HASTE system as currently configured and calibrated did not adequately perform, variations in site analysis and conversion factors may increase pressure sensitivity and tracking over the course of a standard dialysis treatment.     

Evaluation of the effect of shift working and sleep quality on semen parameters in men attending infertility clinic

We aimed to evaluate the effect of shift work on semen parameters together with the effect of sleep quality in men attending infertility clinic. The participants were divided into two groups as follows: 104 shift worker men (Group 1) and 116 nonshift worker men (Group 2). Groups were compared in terms of semen parameters, Depression Anxiety Stress Scale-21 (DASS-21), and Pittsburg Sleep Quality Index (PSQI) scores. A higher rate of oligozoospermia and poor sleep quality and a lower mean normal morphology percentage was observed in shift workers than nonshift workers (p = .006, .039 and .036 respectively). In addition, a positive correlation was seen between sleep duration and sperm concentration, while a negative correlation was found between sleep latency and total sperm count. Shift working together with high PSQI score was also a significant association with oligozoospermia when controlling for the other variables of age, total testosterone, DASS-21 stress score, smoking and varicocele (OR = 2.11, 95% CI 1.03–4.34 and OR = 1.18, 95% CI 1.01–1.39 respectively). In this study, infertile shift workers had a lower percentage of normal morphology and higher rates of oligozoospermia and poor sleep quality. Considering that shift workers have lower sleep quality, it seems that shift working negatively affects the circadian rhythm.     

The best management of superficial bladder tumours: Comparing TUR alone versus TUR combined with intravesical chemotherapy modalities?

To compare retrospectively the recurrence rates of TUR alone versus different intravesical chemotherapy modalities in superficial bladder cancer cases, 187 patients with stage Ta and T₁ bladder tumours were treated with transurethral resection followed by adjuvant intravesical chemotherapy with mitomycin, BCG or epirubicin or by transurethral resection alone. All patients in this study had historically proven transurethrally resectable primary, category Ta and T₁ transitional cell carcinoma (TCC) of the bladder. Group I included transurethral resection alone, and the other groups included intravesical mitomycin-C(Group II), BCG (Group III) and epirubicin (Group IV) therapies after transurethral resection. 146 male and 41 female patients (78% male and 22% female patients) in this study were diagnosed as primary TCC bladder tumours. Only 52 of them were stage Ta and 135 of them were stage T₁ bladder tumours. Examining the histological grade of the bladder tumours, 88 (47%) of the patients had grade I, 53 (28%) had grade IIa, 30 (16%) had grade IIb and remaining 16 (9%) had grade III bladder cancers. The recurrence rates were 25% for Group I, 23.8% for Group II, 26.2% for Group III and 22.7% for Group IV. These values were given with disregarding the grade and volume of the bladder tumours. For solitary, less than 3 cm low grade tumours (grade I, IIa) recurrence rates were 16% for Group I, 15.4% for Group II, 17.8% for Group III, 17.2% for Group IV (p> 0.05). As a result of this retrospective study, for patients with low grade, stage Ta and T₁ tumours TUR alone may be the best treatment modality. Although intravesical chemotherapy is effective in decreasing short-term incidences of tumour recurrence, it has not decreased long-term incidences of tumour recurrence. The high cost and adverse side effects of intravesical chemotherapy should also be taken into consideration in superficial, single, low grade tumours of bladder.

On-the-job training through follow-up visits to improve the quality of family planning services.

As part of a broader set of activities to strengthen family planning training and improve the quality of family planning services in Turkey, follow-up visits were performed at different family planning sites across the country in order to conduct on-the-job training. The objective of on-the-job training was to refresh and improve family planning counselling skills for all methods as well as to refresh and improve intrauterine device insertion/removal skills and also some determinants of quality care. It was also aimed at transferring up-to-date information to family planning practitioners, identifying frequently encountered problems and helping with solution approaches for problems both at the individual and programmatic levels. The results of the follow-up visits reflect issues about both the staff and the clinical facility itself in terms of conforming with the standards of the 'National Family Planning Guidelines' set forth by the Ministry of Health. The follow-up team consisted of nine members who were specially trained. They represented different sectors such as a non-governmental organization, a medical school and the Ministry of Health. The follow-up team performed 90 visits to 16 clinics in 11 provinces between 1995 and 1998. Methods used were structured observations via standard checklists, meetings with the clinic staff, self-assessment, role plays, demonstration, coaching and the provision of feedback. During this period, a total of 130 health professionals working in 16 clinics were trained on-the-job. A significant improvement was observed in the performance of the family planning practitioners and the quality of care provided in clinics. While none of the service providers were found to have a standard skill level in general counselling during the first visit, at the end of the fifth visit all were capable of providing counselling services according to the national standards. Intrauterine device insertion skills were high at the beginning of the visits, and 16 of the 17 observed service providers (94%) were assessed as conforming to the standards. At the fifth visit, all of the 42 service providers (100%) were found to be adequate. At the facility level, all 16 clinics established separate counselling rooms in the follow-up period. Additionally, the number of clinics conforming to infection prevention standards increased from two clinics in 15 at the first visit to all 16 clinics at the fifth visit. This study showed that the ultimate success of family planning programs depend on structured and well-supervised on-the-job training through follow-up visits to the sites.     

Causes of acute poisoning in adults: a retrospective study, in a hospital in Istanbul, Turkey

Aim  

Acute poisoning is one of the major topics in emergency medicine practices. Despite the recent developments in toxicology, technological advances and changing lifestyles reveal new factors, and poisoning cases remain to be a problem. All poisonings should be considered serious and independent from their clinical presentation at the time of admission. Identifying the cause and prompt initiation of treatment is life-saving. Causes of poisoning vary between countries and different regions of the same country. In the present study, cases admitted to the Emergency Department of Internal Medicine at Haseki Training and Research Hospital were evaluated and causes of acute poisoning were investigated.     

Evaluation and Comparison of Charcot’s Triad and Tokyo Guidelines for the Diagnosis of Acute Cholangitis

Reliability of Charcot’s triad has long been questioned. Tokyo Guidelines committee published Tokyo Guidelines in 2007 and 2013. The aim of this study was to retrospectively examine the patients who had been treated with the diagnosis of acute cholangitis and evaluate 2007–2013 Tokyo criteria and Charcot’s triad. The files of the patients with acute cholangitis in a referral center were examined retrospectively. All patients were classified and evaluated according to 2007 and 2013 Tokyo criteria and Charcot’s triad; and results were compared. It was detected that 51.7 % of patients who did not meet Charcot’s triad were in definitive diagnosis group of both Tokyo criteria. Kappa value was calculated as 0.404 in the analysis of consistency between two Tokyo criteria. Two patients who had features sufficient to objectively make the diagnosis of acute cholangitis failed to meet the Tokyo criteria 2007 or 2013. Charcot’s triad is not sensitive and specific enough in the diagnosis of acute cholangitis. Revision of Tokyo 2007 criteria caused a change in the diagnostic status of 15 % of the patients. It is remarkable that kappa value can hardly be considered as a sign of moderate agreement between two Tokyo guidelines. Tokyo criteria should be supported and updated.     

The effect of age on peripheral stem cell mobilization in healthy donors,single center experience

Purpose : Peripheral stem cell transplantation is used as a life‐saving therapeutic option in hematological malignancies. As previously established, most hematological malignancies are seen in the elderly population. Therefore, possible HLA‐identical sibling donors of elderly patients are generally of an advanced age. In this study, we aimed to evaluate the effect of old age on stem cell mobilization and quality in older adult healthy sibling donors. Materials and Methods : Between 2006 and 2014, we evaluated 38 healthy donors aged ≥55 years. The granulocyte‐colony stimulating factor (G‐CSF) analogs were used at a dose of 5 µg/kg/day and administered subcutaneously twice a day for five days. CD34+ cells were estimated in the peripheral blood before collection of the apheresis product. The National Marrow Donor Program selects healthy unrelated donors if they are younger than 60 years. Therefore, we compared the product quality in donors over the age of 60 to that in donors aged 60 years or less. Results : We collected sufficient products from all the donors with one to three apheresis procedures. No serious complication was detected in all donors. Reaching the target CD34+ cell count in one day were detected in 83% of younger and 79% of older donors (P = NS). Collected CD34+ cells x10e6/recipient body weight (kg) was same and 5.1 in the groups (P = NS). There were no correlation between the donor age and these parameters. Conclusion : Healthy donor apheresis in older adults can be performed effectively and possible donors should be evaluated regardless of their age. J. Clin.
