Symphisis Pubis Stress Fracture: Case Report
Türkiye Fiziksel Tip ve Rehabilitasyon Dergisi , 2008,
Abstract: There are two kinds of stres fracture. One is fatigue fracture of a healthy bone during unusual mechanical overloading. This kind is seen particularly in young persons, such as athletes and most often affects the metatarsals, calcaneum, tibia and fibula. The second kind is insufficiency fracture, in which the bone has become fragile because of age, metabolic disorder, or prior orthopedic surgery and cannot withstand even moderate stress. This type of fracture particularly affects the elderly, and is by far most frequent in the pelvis. Diagnosis can be difficult if it is based only on the initial plain radiographs. Generally magnetic resonance imaging, bone sintigraphy and computed tomography are useful in localizing and diagnosing fractures. Good clinical results can be obtained with non-surgical treatment. Here we aimed to present the case of a young healty male adult presenting with symphisis pubis insufficiency fracture which occured secondary to osteopenia. Turk J Phys Med Rehab 2008;54:181-3.
Cervical Intermittent Traction: Does it Really Work in Cervical Radiculopathy Due to Herniated Disc?
Türkiye Fiziksel Tip ve Rehabilitasyon Dergisi , 2012,
Abstract: Objective: Cervical intermittent traction is commonly used for the treatment of neck pain, predominately with nerve root involvement due to herniated disc or cervical spondylosis, however, there is no precise information on its effectiveness. The aim of this prospective randomized controlled trial was to compare the difference between two treatment protocols (regular physical therapy treatment -hotpack, ultrasound, TENS- and exercise, with or without traction) in the treatment of cervical 7 radiculopathy as a result of herniated disc.Materials and Methods: 27 patients with unilateral C7 radiculopathy due to herniated disc verified by magnetic resonance imaging were recruited and randomly assigned to one of the two treatment groups (traction and control group). Traction group received regular physiotherapy, exercise, and intermittent cervical traction whereas control group received regular physiotherapy and exercise for 15 sessions (5 sessions per week). Primary outcome measures were the visual analogue scale and maximum grip strength of the affected side recorded at baseline and discharge. Results: Statistical analysis revealed a significant increase in grip strength and significant decrease in visual analogue scale after 15 physiotherapy treatment sessions in both groups compared with pretreatment score (p=0.001 and p=0.001, respectively). The change in grip strength and in visual analogue scale after 15 sessions was significantly higher for the traction group than for the control group (p=0.037 and p=0.042, respectively) Conclusion: Traction with regular physiotherapy modalities (hotpack, ultrasound, TENS) accompanied by home exercises for three weeks increased hand grip strength on the affected arm and reduced neck and arm pain substantially in C7 radiculopathy due to herniated disc.

Case Reports in Pathology , 2013, DOI: 10.1155/2013/375193
Abstract: Pancreatic dermoid cysts are a rare entity. Preoperative diagnosis is difficult. The diagnosis is generally taking intraoperative. A 20-year-old female presented with epigastric pain without nausea, vomiting, diarrhea, fever, jaundice, and weight loss of one-month duration. Ultrasonography and computed tomography showed a smooth borders, solid, hyperechoic tumor within midline abdomen, without any connection to the stomach or spleen. At surgery, the entire mass was excised off of the head and inferior part of pancreas. Histopathologic evaluation revealed the rare diagnosis of a dermoid cyst. The diagnosis is difficult preoperatively in evaluating cystic pancreatic lesions by imaging. Therefore, we want to summarize the literature on this rare entity knowledge. 1. Introduction Dermoid cysts are congenital developmental abnormalities of germ cell origin derived from any of the three germinal layers, that is, ectoderm, entoderm, and mesoderm. Teratomas usually occur along the midline of the body, which is the route of germ cell migration during embryogenesis. These migrating germ cells may become “misplaced” en route to their appropriate organs, leading to the development of tumors later in life. The pancreas is extremely rare as a primary site. As true cysts, dermoid cysts are usually benign, well differentiated lesions. Pancreatic teratomas probably originate from aberrant germ cells arrested in migration to the gonads early in embryonic life. They are composed of tissue derived from any of the three germinal layers and may produce a wide variety of structures with different degrees of differentiation, including hair, teeth, cartilage, bone, and dermal appendages, such as hair follicles, sweat glands, and sebaceous material [1, 2]. They are an unusual entity with only 30 cases, to our knowledge, described in the world literature. We report the 31st case of a pancreatic cystic teratoma. 2. Case-Report A case of a 20-year-old woman was admitted to our hospital due to vague epigastric pain without nausea, vomiting, diarrhea, fever, jaundice, and weight loss of one-month duration. The patient had no significant medical history. A physical examination demonstrated mild tenderness in the epigastrium but no evidence of an acute abdomen. Laboratory studies including functional tests of the pancreas, and the liver and kidneys showed normal values. The levels of serum carbohydrate antigenic determinant (CA19-9) and carcinoembryonic antigen (CEA) were not elevated. A CT scan revealed a lobular contoured solid mass with a 13?cm long axis, 6?cm transverse diameter,
Clustering of protein families into functional subtypes using Relative Complexity Measure with reduced amino acid alphabets

Abstract: We demonstrate the robustness of RCM with reduced alphabets in clustering of protein sequences into families in a simulated dataset and seven well-characterized protein datasets. On protein datasets, crotonases, mandelate racemases, nucleotidyl cyclases and glycoside hydrolase family 2 were clustered into subfamilies with 100% accuracy whereas acyl transferase domains, haloacid dehalogenases, and vicinal oxygen chelates could be assigned to subfamilies with 97.2%, 96.9% and 92.2% accuracies, respectively.The overall combination of methods in this paper is useful for clustering protein families into subtypes based on solely protein sequence information. The method is also flexible and computationally fast because it does not require multiple alignment of sequences.Proteins that evolve from a common ancestor can change functionality over time [1] and produce highly divergent protein families that can be divided into subfamilies with similar but distinct functions (i.e., functional subfamilies or subtypes) [2]. Identification of subfamilies using protein sequence information can be carried out using phylogenetic methods that can reveal the evolutionary relationship between proteins by clustering similar proteins together in a phylogenetic tree [3-5]. The most common method for identifying similarities in sequences through phylogenetic analysis starts with the construction of a multiple alignment of homologous sequences using a substitution matrix. Multiple alignment scores are then transformed into a distance matrix to construct a phylogenetic tree. Often the branching order of a phylogenetic tree exactly matches the known functional split between proteins [1] and branch lengths are proportional to the extent of evolutionary changes since the last common ancestor.Multiple sequence alignment (MSA) is constructed using a scoring scheme which reward or penalize each substitution, insertion and deletion to get an optimum alignment of the given sequences.

Abstract: Objectives: In this prospective study, we compared primary closure and Karydakis flap repair which has recently proved a popular technique for surgical treatment of pilonidal sinus.Patients and Methods: The study included 48 patients (46 males, 2 females) who were operated on for pilonidal sinus. The patients were randomized to two groups. After sinus excision, 33 patients (group 1) underwent primary closure, and 15 patients (group 2) underwent Karydakis flap surgery. The mean followup was 6.8 months (range 4 to 11 months) in group 1, and 6.2 months (range 3 to 10 months) in group 2.Results: Serous liquid collection and discharge were seen at the site of the lesion in four patients (12.1%) in group 1, and in two patients (13.3%) in group 2. Subcutaneous hematoma was detected in one patient (6.7%) in group 2. During the follow-up period, none of the patients developed wound infection. Recurrences were seen in one patient (3%) in group 1, and in one patient (6.7%) in group 2.Conclusion: Excision and primary closure can be the preferred method for the treatment of pilonidal sinus in selected patients due to its advantages such as ease and simplicity, shorter recovery time, and limited scar formation.
Drugs Induced Stevens-Johnson Syndrome
Duzce Universitesi Tip Fakültesi Dergisi , 2010,
Abstract: Stevens Johnson Syndrome (SJS) is a life threatening mucocutaneous skin disease that mostlydeveloped after using some drug. SJS mostly appear between 2-4th decades. Mucocutaneouslesions were seen between 1-14 days of drug intake. And these lesions spread diffusely all aroundthe body. First treatment choice is the stopping of drug that cause SJS and giving supportingtreatment. After understanding of underlying cytotoxic and immunological mechanism of SJS,new treatment approaches were developed and mortality of disease was reduced. We hereinreport a short review of drug induced SJS and its treatment.
Good prediction of an anemic patient

Abstract: Anemias are a group of disease which draw the interest of by all clinicians as well as hematologists. An algorithm of anemia diagnosis by test parameters decreases the unuseful tests and prevents false diagnosis. Such schema must contain well-chosen tests and parameters. Complete blood count, mean corpuscular volume (MCV), red cell distribution width (RDW), serum iron level, reticulocyte count, hemoglobin electrophoresis and direct Coombs test are most important measures. Even isolated Hb decrease, MCV decrease and RDW increase can predict near correct diagnosis of iron deficiency anemia. A response to iron treatment confirms the diagnosis. We think that the algorithm in our paper can facilitate the differential diagnosis of anemia by minimum test count. (Turk Arch Ped 2009; 44 Suppl: 1-5)

International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.612102
Abstract: In this paper, it is both intended to effectively transfer and emphasize the relationship between geospatial data and software applications while presenting the learning activities which required software competences and presented some software techniques related with geomatic engineering. Effective software competence in geomatic is required for both the combination of information-communication technologies and interdisciplinary collaborative learning activities. The essential way to keep up with future competences is adaptation to different types of information technologies. Today, it is obviously seen that the using of interest-activated technology is a sine qua non condition of engineering education. The main focusing point of this paper is to present some learning suggestions while developing a software related course content in Geomatic to empower engineering education.

Abstract: The aim is to present a case operated due to one-month ongoing intussusception and diagnosed as lymphoma. A six years old boy was admitted to our emergency department with complaint of colicky abdominal pain and bilious vomiting for the last month. He was operated due to 3 cm intussusception at ileocecal part. A mass which is about 6 cm in diameter, hard, partly mobile and invaginate the intestine at its posterior aspect was found. Pathology was reported as Burkitt lymphoma. He received two cycles of chemotherapy at post-operative period. He is still event free for the last two years. One must remember that lymphoma can be the lead point in intussusception especially in elderly children.
