Atopic Dermatitis: Disease Features, Therapeutic Options, and a Multidisciplinary Approach.

The latest findings regarding AD pathogenesis point to an impaired function of the epidermal barrier, changed immune response, colonization of the skin by microorganisms, and certain psychological factors among other causes/triggers. The inflammatory response of AD patients is mainly associated with the activation of T cells (Th2 cells predominate), dendritic cells, macrophages, keratinocytes, mast cells, and eosinophils. Therapy usually involves medical evaluations and adequate management including treatment of concomitant diseases (e.g., allergies and infections), patient education and nursing care, psychological support, and nutritional consultations, which are organized through specific programs and structured educational groups. Systemic AD therapy includes conventional systemic treatment (cyclosporine, methotrexate, azathioprine) and new, specific drugs, interleukin inhibitors (e.g., dupilumab) and JAK inhibitors (baricitinib, abrocitinib, upadacitinib, etc.). Since many AD patients are affected by various psychological factors and comorbidities, they should be assessed and managed through a multidisciplinary approach, involving different professions (psychologists, ear-nose-throat specialists, pulmonologists, allergologists, immunologists, nutritionists, pediatricians, gastroenterologists, psychiatrists (when necessary), and others). A multidisciplinary approach provides better coping strategies and improves control over the disease, patient adherence to therapy, and quality of life. It also has a positive influence on family quality of life while at the same time making more efficient use of dermatology healthcare resources, reducing the economic burden on both patients and society.

SERUM LEPTIN LEVEL IN BREAST CANCER.

Leptin is a polypeptide which is mostly produced in white fat tissue and is an important proinflammatory, proangiogenic, proinvasive and mitotic factor. There is ever more evidence suggesting the key role of leptin in the occurrence of breast cancer. The aim of the study was to investigate serum leptin levels in patients with benign breast tumors, as well as in various breast cancer phenotypes, taking into account leptin levels connected to menopausal status and body mass index (BMI). The study included 97 patients having their breast tumor surgically removed. Serum leptin level was determined by ELISA method in all study patients. Study results showed that significantly more women, regardless of having malignant or benign tumors, were postmenopausal and had a significantly higher level of leptin compared to the premenopausal group. The highest level of leptin was recorded in the group of postmenopausal obese women compared to other postmenopausal women but also compared to premenopausal women. According to BMI alone, obese women had a significantly higher level of leptin regardless of the type of tumor. The most significant differences in leptin levels observed through BMI were found in the Luminal B1 group. In conclusion, serum leptin level was shown to be a good diagnostic parameter suggesting a higher possibility of breast cancer development.

Histological analysis of cross-sectional area of quadruple hamstring tendons and patellar ligament samples in relation to age and gender.

AIMS: The middle of the patellar ligament and the quadruple hamstring tendons (gracilis and semitendinosus) are two types of graft predominantly used in anterior cruciate ligament (ACL) reconstruction. The aim of this study was to determine the morphometric characteristics of patellar ligament grafts and hamstring tendon grafts and to compare the results according to subject age and gender. MATERIALS AND METHODS: The study was conducted on a total of 120 samples: 40 of gracilis tendon, 40 of semitendinosus tendon and 40 of patellar ligament, distributed equally according to gender, age (50-75 years) and the side of the body from which the sample was harvested. RESULTS: Morphometric and histological analyses showed that patellar ligament samples had less cross-sectional area than quadruple tendon samples (49.29 mm(2) compared with 51.46 mm(2), respectively). Sexual dimorphism was noticed in distal cross-sections of gracilis tendons (p=0.09), cross-sections of quadruple tendons (p=0.07) and patellar ligament samples (p=0.01) because of different muscular build. CONCLUSIONS: All samples obtained from male subjects had larger cross-sectional areas compared with the samples taken from females. Furthermore, samples obtained from subjects aged 60 years or under had larger cross-sectional areas than samples obtained from subjects aged at least 61 years for all types of graft.

Cardiopulmonary resuscitation, chest compression only and teamwork from the perspective of medical doctors, surgeons and anesthesiologists.

BACKGROUND: New resuscitation guidelines that were proposed by the European Resuscitation Council in 2010 have introduced a new method of cardiopulmonary resuscitation (CPR) by chest compressions only for untrained individuals. OBJECTIVES: We conducted this study to evaluate differences in attitudes towards CPR among medical doctors, surgeons and anesthesiologists in Osijek University Hospital. A call for help, chest-compression-only resuscitation, mouth-to-mouth ventilation and team-work were recognized as critical points that may influence the outcome. Unfamiliarity with these methods may be indicative of a lack of education in resuscitation and may result in poor outcomes for victims. PATIENTS AND METHODS: An anonymous survey was conducted on 190 medical professionals: 93 medical doctors, 70 surgeons, and 27 anesthesiologists during year 2012 (mean age 41.9 years). The questions were related to previous education in resuscitation, current resuscitation practices and attitudes towards cardiopulmonary resuscitation. Data were analyzed using ANOVA and Fisher exact test. A P value of < 0.05 was considered statistically significant. RESULTS: The only difference between groups was regarding the male and female ratio, with more male surgeons (45, 55, and 11, P < 0.001). All doctors considered CPR as important, but only anesthesiologists knew how often guidelines in CPR change. Approximately 45% of medical doctors, 48% of surgeons and 77% of anesthesiologists reported that they have renewed their knowledge in CPR within the last five years, whereas 34%, 25% and 22% had never renewed their knowledge in the CPR (P = 0.01 between surgeons anesthesiologists). Furthermore, chest-compression-only was recognized as a valuable CPR technique by 25.8% of medical doctors, 14.3% of surgeons and 59.3% of anesthesiologists (P < 0.001). Anesthesiologists estimated a high risk of infection transmission (62%) and were more likely to refuse mouth-to-mouth ventilation when compared to surgeons (25% vs.10%, P = 0.01). Anesthesiologists are most often called for help by their colleagues, only rarely surgeons call their departmental colleagues and nurses to help in CPR. CONCLUSIONS: An insufficient formal education in CPR was registered for all groups, reflecting the lack of familiarity with new CPR methods. A team education, involving doctors and nurses may improve familiarity with CPR and patient outcomes.

Reducing pain and improving quality of life for patients suffering the acetabular fracture.

The rationale for this paper was to find out assessment tools and relevant factors that may reduce pain, and improve the quality of life and ability to perform activities of daily living in surgically and conservatively treated patients who sustained the acetabular fracture. One hundred and three patients with the acetabular injury were analysed during the 10-year retrospective case-control study. The case group consisted of 21 patients in whom the posterior acetabular wall was fractured and who were treated surgically. The control group comprised 82 patients with complex acetabular fracture in whom conservative treatment was applied. In order to assess post injury and postoperative quality of life different factors, such as the intensity and chronicity of pain, as well as the ability to resume activities of daily living, the patients were surveyed by anamnestic questionnaire to acquire the results. The quality of life was mostly better in patients from the case group who were operated on. At the follow-up, the features of pain were lower, management overall length shorter, and return to normal daily life activities faster in the surgically treated patients, compared to those who were not. In conclusion, based on our research we assume that surgery may notably decrease features of pain and improve the quality of life in patients with the acetabular injury.

The relevance of surgery in the acetabular injury management outcome.

INTRODUCTION: The purpose of this article was to analyze diverse factors that affect the management outcome of the acetabular injury in different groups of patients. METHODS: The cohort of 103 patients suffering the acetabular fracture was analysed in a retrospective case-control study. The case group was comprised of 21 patients in whom the posterior acetabular wall was fractured and who were treated surgically, while the control group was formed from 82 conservatively treated patients suffering complex acetabular fracture. The appearance and rate of different complications, and the treatment overall length were observed as a measure of outcome. RESULTS: Lower limbs flebothrombosis and a pulmonary embolism were the most often complication in the control group of patients, but were rarely observed in surgically treated patients, in whom the management duration was considerably shorter. At a 3-year follow-up the acetabular injury management outcome in the case group was significantly better, compared to the control group of patients. CONCLUSION: Surgery may improve the outcome and reduce the rate of complications and the length of treatment for the patients suffering the acetabular injury.

Influence of surgery onto the appearance of the hip joint periarticular calcification in patients with the acetabular fracture.

The intention of this study was to investigate the influence of surgery onto the appearance of the hip joint periarticular calcification in different groups of patients who suffered the acetabular fracture. A series of 103 patients with the acetabular fracture was analysed in a retrospective case-control study during a seven-year period. The patients were divided into two groups. The case group was comprised of 21 patients who were operated on due to the posterior acetabular wall fracture, while the control group was formed from 82 patients who underwent conservative treatment and who suffered complex acetabular fracture. To obtain the results, the rate and grade of the hip joint post-injury periarticular calcification formation were observed and analysed. They were considerably lower in patients from the case group who were operated on, compared to patients from the control group where the hip joint arthrosis was more common. In conclusion, considering the results of this paper, the rate and grade of the hip joint osteodegenerative changes may be highly decreased by surgery in patients who sustained the acetabular fracture.

Spontaneous regression of intervertebral disc herniation--case reports.

Lumbar disc hernia (LDH) is a common cause of low back pain and radicular leg pain. It is well known that the majority of LDH patients recover spontaneously. Since the advent of MRI, a spontaneous regression of fragment size of disc hernia occurs, as well as mitigation of subjective difficulties and neurological disorders. Therefore, surgical treatment is not always method of choice in this disease. Two cases of conservatively treated large disc extrusion which result in significant reduction of difficulties, with simultaneous reduction in fragment size of hernia which is documented by MR.

The proximal femoral nail antirotation (PFNA) in the treatment of proximal femoral fractures.

Proximal femoral fractures, especially in elderly persons with osteoporosis, present a challenge for the traumatologist. While the dynamic hip screw (DHS) became the implant of choice for the treatment of stable fractures, the ideal implant for the treatment of unstable fractures remains an issue. In our experience, Proximal Femoral Nail Antirotation (PFNA) is an excellent device for osteosynthesis as it can be easily inserted, it provides angular and rotational stability and allows early weight bearing on the affected limb. Between February 2007 and August 2009, 76 patients underwent the PFNA fixation for proximal femoral fractures (15 men and 61 women). Forty seven fractures were pertrochanteric, 14 subtrochanteric, 2 pathological and 5 ipsilateral trochanteric and diaphyseal fractures whereas in 8 cases the PFNA was used in reosteosynthesis. The mean age of patients was 73.4 years (range 22-91 years). The fractures were reduced on a traction table and the implant was inserted using minimally invasive technique. Four patients developed superficial postoperative wound infection. No cases of implant breakage have been recorded; there was one cut-out; delayed union was noted in three patients. The majority of patients regained their pre-injury mobility status. The PFNA is an excellent implant for stabilisation of both trochanteric and complex combination fractures as well as an exceptional device for reosteosynthesis. It is easily inserted with few intra- and postoperative complications and allows early weight bearing on the affected limb as well as quicker rehabilitation of patients.

The main biomechanical risk factors for the prevalence of the left hip joint traumatic and degenerative changes.

The aim of this paper is to examine characteristic biomechanical features leading to the acetabular fracture and hip joint arthrosis, and to explain the prevalence of the left side traumatic and degenerative pelvic pathology that is usually seen in diverse groups of patients. A total of 253 patients were analyzed in a retrospective case-control study during a six-year period. The patients were divided into the case group of 103 patients suffering traumatic acetabular fractures and into the control group of 150 patients with hip joint arthrosis, where operative aloarthroplasty was not yet performed. The data of the affected hip joint range of motions in the case and control group of patients were statistically analyzed correlating the difference in frequency of the left and right hip joint pathology. The left acetabulum was affected more commonly in both groups of patients, while arthrosis of the left hip joint was more commonly recorded in the control group. More frequent pathology of the left hip joint, found in both groups of patients, was probably due to weaker neuromuscular function of the left pelvic side, which was also more exposed to injury due to the greater input of forces to the left hip joint during a traffic accident.

Functional status of hip joint after surgical and conservative treatment of acetabular fracture.

Both conservative and surgical treatment of acetabular fractures alter biomechanical conditions in the hip joint resulting in various degenerative changes in the acetabulum and the femur head. These changes may progress to secondary coxarthrosis, causing dysfunction of the hip joint. The aim of this paper is to compare the outcomes of both conservative and surgical treatments in different types of acetabular fractures, so that clear indications for either conservative or surgical treatment could be determined. This paper is based on retrospective study of 103 patients with acetabular fracture (21 surgically treated and 82 conservatively treated). In this study the incidence of particular types of acetabulum fractures, the treatment period, the incidence of complications and the functional status of the hip after the treatment were analyzed. In patients with anterior fracture surgical treatment lasted three times less than conservative treatment and resulted in far better functional status of the hip joint compared to conservatively treated patients. However, in patients with transverse fractures the functional status was better and the treatment period shorter after the conservative treatment. We believe that the present treatment indications should be corrected so that in anterior column fracture the surgical method should be preferred, whereas the transverse fracture should be treated conservatively. In other types of acetabular fracture, with the radiographic roof arc angle of 45 degrees or less, the surgical method should be preferred to conservative method.

[Stagewise treatment in taking care of firearm wounds]. / Etapno lijecenje u zbrinjavanju strijelnih ozljeda.

A case of stagewise treatment of open fracture caused by firearm wound of the upper arm in a 69-year-old male is presented. The accident resulted with extensive firearm wound in the middle third of the left upper arm with third degree open fracture. The hand's functional and neurocirculatory status was completely preserved. On arrival, external fixator was positioned on the left upper arm. Postoperative course was without complications, and secondary stitches were placed. After sanation of the wounds, the fracture was definitely managed by DC plate with 9 cortical screws and corticospongioplasty. After fracture sanation and completed physical treatment, a satisfying magnitude of movement in elbow and shoulder area was achieved.

Supracondylar fractures of the humerus in children caused by traffic.

A sample of 38 patients aged under 14 treated at the Surgery Clinic of the University Hospital Osijek has been used in showing therapeutic guidelines supported by patients' functional status after the completed treatment. The patients suffered from supracondylar fractures caused by traffic accidents and classified into three types according to Gartland. Not a single patient with neurocirculatory disturbances has been registered. The most common treatment was a conservative one while more than half of the patients with fractures from type III underwent surgery. The duration of immobilization approximated three weeks whereas patients' recovery considering their functional status has justified the choice of the treatment. However, a lot can be done in the field of prevention, which would greatly decrease the frequency of such injuries.

The analysis of the unstable tibia fracture treatment applying internal stabilization method.

The study included 51 patients with tibia fractures, who underwent percutaneous bone reposition and stabilization with unrimed tibial locking nail. The results obtained using this method were compared with those obtained by standard fracture treatment where flat and anatomic plates were applied (n = 64). In patients who had osteosynthetic material implanted percutaneously (using unrimed tibial locking nail) there was no incidence of post surgical osteitis or any pseudarthrosis. The healing callus of the fracture was of lesser quality and spindle shaped, suggesting that fracture stabilization using this method was less efficient. In patients with fractures stabilized by the open method using flat and anatomic plates (n = 64), we noticed 3.1% (n = 2) cases of osteitis and 4.7% (n = 3) cases of pseudarthrosis. Due to lesser incidence of postoperative osteitis, our method of choice in tibia fractures would be percutaneous stabilization with unrimed tibial locking nail. However, this treatment method has its disadvantages, too. Fracture callus is of lesser quality and it is spindle shaped. Furthermore, there are problems with adequate percutaneous reposition in some cases, as well as necessity for radiological checking.
