Treatment of Ileus after hysterectomy with Drain and medical applications; a case repor
Postoperatif ileus (POI), önemli morbidite ve mortalitesi olan karmaşık bir olgu olup, birçok cerrahi alanda görülebilmektedir. Bilinen riski olmayan 50 yaşında bir kadın hastaya tedaviye dirençli menometroraji tanısı ile total abdominal histerektomi ve bilateral salpenjeooferektomi (TAH+BSO) uygulandı. Peroperatif ve postoperatif dönemde herhangi bir problemi olmayan, gaz gaita çıkışı gözlemlenen hasta postoperatif 4. günde taburcu edildi. Ancak postoperatif 6. günde kusma karın ağrısı (akut batın tablosu) ile acil servise başvurduğunda kliniği, tahlilleri ve görüntüleme yöntemleriyle ileus gelişmiş olduğu saptandı. Bunun üzerine, hastada oral alım kapatıldı, medikal tedavi olarak metoklopramid ve laktasif lavman başlandı. Yapılan görüntülenme yöntemlerinde batın içi ve cilt altı ileusa bağlı seröz sıvı izlendi ve hastaya cilt altı hemovac dren konularak batın rahatlatıldı. Yaklaşık 5 gün içinde re-operasyona gerek duyulmadan hastanın ileusu sonlandı ve hasta şifa ile taburcu edildi. Biz bu olgu sunumumuzda basit ama etkili yöntemlerle POI’nin önlenip, erken dönemde operasyona gerek kalmadan, tedavi edilebileceğini göstermiş olduk.Postoperative ileus (POI) is a complex phenomenon with significant morbidity and mortality and can be seen in many surgical fields.
A 50-year-old woman with no known risk was diagnosed with treatment-resistant menometrorrhagia and underwent total abdominal
hysterectomy and bilateral salpingeooophorectomy (TAH+BSO). The patient, who did not have any problems in the perioperative and
postoperative periods, and gas-fecal output was observed, was discharged on the 4th postoperative day. However, on the 6th postoperative
day, when he applied to the emergency service with vomiting and abdominal pain (acute abdomen), ileus was found to have developed by
his clinic, analyzes and imaging methods. Thereupon, oral intake was stopped in the patient, and metoclopramide and lactase enema were
started as medical treatment. In the imaging methods performed, serous fluid related to the intra-abdominal and subcutaneous ileus was
observed and the patient was relieved by placing a subcutaneous hemovac drain. In about 5 days, the patient's ileus ended without the need
for re-operation and the patient was discharged with full recovery. In this case report, we have shown that POI can be prevented and treated
without the need for an operation in the early period with simple but effective methods
Effect of Nasopharyngeal Irrigation on Early Eustachian Tube Functions in Patients Undergoing Adenoidectomy: A Clinical Prospective Study
Objective:The hypertrophic adenoid tissue can cause to eustachian tube dysfunction by mechanical or inflammatory effect both of which block the nasopharyngeal ostium of the eustachian tube. Adenoidectomy, with or without tonsillectomy, is the most common surgical procedure in children. In this study, we aimed to investigate whether nasopharyngeal irrigation for hemorrhage control in adenoidectomy patients has an effect on eustachian tube functions.Method:Patients who underwent adenoidectomy for adenoid hypertrophy evaluated on both the preoperatively and on the postoperative first day by otomicroscopic examination and with tympanometry for eustachian tube functions. Patients were divided into two groups according to nasopharyngeal irrigation type after surgery. Group 1 was the transnasal pressure irrigation group; group 2 was transoral passive irrigation group. Tympanometry was used to measure pressure, volumetric, and compliance values to compare pre- and postoperative values.Results:40 patients were included in the study. There was no significant difference between the age and sex distributions of the patients. Volume and compliance values between the groups were similar before and after the surgery. The mean pressure values of the tympanometry parameters were highly significantly different for the right ear and moderately different for the left ear in group 1; were significantly different for the right ear and highly significantly different for the left ear in group 2. Postoperative tympanometry types were seen as bilateral type C in 7 patients, as right side type C in 4 patients, as bilateral type B in 2 patients, as left side type C in 4 patients in group 1. However, in group 2, right side type B, left side type B and bilateral type C tympanogram were observed in 1 patient, 2 patients and 12 patients, respectively.Conclusion:In this study, we observed that the nasopharyngeal irrigation to control bleeding after adenoidectomy had adverse effect on the eustachian tube functions but larger series of studies are needed to confirm this
Rationale, design, and methodology of the MORCOR-TURK trial: predictors of in-hospital MORtality in CORonary care patients in Turkey
Background: Coronary care units are sophisticated clinics established to reduce deaths
due to acute cardiovascular events. Current data on coronary care unit mortality rates
and predictors of mortality in Turkey are very limited. The MORtality predictors in
CORonary care units in TURKey (MORCOR-TURK) trial was designed to provide information on the mortality rates and predictors in patients followed in coronary care units in
Turkey.
Methods: The MORCOR-TURK trial will be a national, observational, multicenter, and
noninterventional study conducted in Turkey. The study population will include coronary care unit patients from 50 centers selected from all regions in Turkey. All consecutive patients admitted to coronary care units with cardiovascular diagnoses between
1 and 30 September 2022 will be prospectively enrolled. All data will be collected at one
point in time, and the current clinical practice will be evaluated (ClinicalTrials.gov number
NCT05296694).
In the first step of the study, admission diagnoses, demographic characteristics, basic
clinical and laboratory data, and in-hospital management will be assessed. At the end of
the first step, the predictors and rates of in-hospital mortality will be documented. The
second step will be in cohort design, and discharged patients will be followed up till 1 year.
Predictors of short- and long-term mortality will be assessed. Moreover, a new coronary
care unit mortality score will be generated with data acquired from this cohort.
Results: The short-term outcomes of the study are planned to be shared by early 2023.
Conclusion: The MORCOR-TURK trial will be the largest and most comprehensive study in
Turkey evaluating the rates and predictors of in-hospital mortality of patients admitted
to coronary care units
A Study On Room Temperature Straın Agıng Of Dual-Phase Steels
Otomotiv sektöründe geniş kullanım alanı olan çift fazlı çeliklerin oda sıcaklığında gerinim
yaşlanması sonundaki çekme özellikleri araştırılmıştır. Bu amaçla DP600 çift fazlı çeliği
kullanılmıştır. Ayrıca bu çelikler 890 oC'den su verilip ardından tekrar 733 oC sıcaklıklarda
su verilerek ferritik matriste daha fazla martensit hacim oranı üretilmiştir. İki farklı ferrit +
martensit mikroyapısına sahip bu çelik numunelere %6 ve %12 ön gerinim yapılmış daha
sonra oda sıcaklığında 1-2-3 ve 4 ay süre sonunda gerinim yaşlanması uygulanmıştır. Çift
fazlı çeliklerin oda sıcaklığı statik gerinim yaşlanma süresi ve artan martensit hacim oranına
bağlı olarak sertlik, akma ve maksimum çekme gerilme değerleri artmış olup, genel olarak
kopma birim uzama değerlerinde düşüş olduğu görülmüştür. Kırık yüzey incelemelerinde
ise yine artan yaşlanma süresi ve martensit hacim oranına bağlı olarak taneler arası sünek
kırılmadan tane içi gevrek kırılma davranışına doğru bir eğilim gerçekleşmiştir. Bu çalışma
ile şekillendirilen çift fazlı çeliklerin oda sıcaklığında mekanik özelliklerinin önemli ölçüde
değişeceği ve bu çeliklerin temel özelliği olan sürekli akma davranışlarının zamanla
yitirileceğini gösterilmiştir.The tensile properties of dual phase steels, which are widely used in the automotive sector,
at the end of strain aging at room temperature were investigated. For this purpose, DP600
dual phase steel was used. In addition, these steels were water-quenched from 890 oC and
then re-quenched from 733 oC and thus more martensite volume ratio in the ferritic matrix
were produced. 6% and 12% pre-strain to steel samples having two different ferrite plus
martensite microstructures were applied and then strain aging at room temperature for 1-2-
3 and 4 months were carried out. Depending on increasing room temperature static strain
aging time and martensite volume fraction of dual phase steels the hardness, the yield and
ultimate tensile stress values of the steels were increased and it was observed that there was
a decrease in the breaking elongation values in general. On the other hand, a tendency toward
trans granular brittle fracture behavior has been observed in the fracture surface by
increasing aging time and martensite volume ratio. By this study, it has been shown that the
mechanical properties of formed dual phase steel will change significantly and continuous
yield behavior, which is the main properties of these steels, will be lost in time
Surgery Dissector: Surgical Device Production With 3D Print Technology
Three dimensional (3D) print technology usage is becoming more popular in medicine and surgicalsciences. There is a couple of study about using 3D print technology for surgical device production andneurosurgery in the literature. In order to adjust dissector measurements to use during the surgical operation,from patient’s CT and MRS outputs, spinal canal diameters, nerve root attached foramen diameters and discgap wideness of the patient were measured. With these measurements, surgery dissector modelling was doneby using Solidworks 3D CAD program in Dokuz Eylul University, Department of Biomechanics. Polylacticacid(PLA) filament was used in the devices during print process. In our study, surgical dissectors’ sterilization wasdone with vapor in 1200C and used in an operation for lumbar narrow canal diagnosed patient whosemeasurements were checked before the surgery. There isn’t any intraoperative complication observed <div style="padding: 0px; margin: 0px; position: absolute; cursor: text; transform-origin:
