Knee joint pain is one of the most common complaints related to the skeletal system
encountered by paediatricians. Knee joint pain generally occurs as the result of hypermobility and
growing pains, though disorders manifesting as arthritis/arthralgia and orthopaedic problems
should be considered in the differential diagnosis. A thorough and careful physical examination
and laboratory and radiological findings are of importance for an accurate diagnosis. Although
treatment should be based on the aetiology of the knee pain, non-steroid anti-inflammatory drugs
can be used to alleviate the pain. A 7-year-old male patient presented with recurring pain in the left
knee. Physical examination of the patient, laboratory tests, and radiological examination of the knee
joint were normal; roentgenograms performed for a presumed hip joint problem revealed a focal
cortical defect on the left femoral head and an increased effusion in the left hip joint space compared
with the right counterpart. With this case report, we would like to highlight that paediatric health
and diseases specialists (paediatricians) should consider hip joint pathologies when patients present
with knee pain, particularly knee pain with an unidentified aetiology.

Objective:
Endometriosis is a common gynecological disease among reproductive-age women. Numerous hypotheses exist regarding the pathogenesis of endometriosis. In Turkey, the consumption of Allium cepa (commonly known as the “onion cure”) is a popular treatment employed to alleviate a variety of gynecological disorders.
Methods:
In this study, our objective was to assess the therapeutic mechanisms of the onion bulb A. cepa using an autologous endometriosis model in Sprague-Dawley rats. Previous research has shown that A. cepa possesses anti-inflammatory, antioxidant, and antiapoptotic properties. We evaluated the pathological condition of endometriotic implants by employing hematoxylin-eosin staining and Ki67 immunohistochemistry analysis. Transforming growth factor-beta 1 (TGF-β1) and alpha-smooth muscle actin (α-SMA) have been identified as profibrotic markers that are highly overexpressed in endometriotic tissues relative to eutopic endometrial tissue. Furthermore, TGF-β1 influences the differentiation and progression of endometriosis. To quantify profibrotic activity, we measured TGF-β1 and α-SMA using the immunosorbent assay method.
Results:
Lower histologic evaluation scores for endometriotic implants were observed in the group receiving high-dose A. cepa relative to the other groups. Ki67 expression was reduced following the high-dose A. cepa regimen, which consisted of 30% A. cepa and 70% normal feed. However, no statistically significant differences in TGF-β1 or α-SMA levels were observed among the groups (p=0.7 and p=0.778, respectively).
Conclusion
The findings suggest that A. cepa could serve as a therapeutic agent in endometriosis treatment, as evidenced by the reduction in proliferative potential. Nevertheless, A. cepa was not associated with significantly lower levels of endometriosis-associated TGF-β1 or α-SMA.

Clinical and Experimental Vaccine Research 2022;11(1):1-11
Purpose:
Lumpy skin disease (LSD) is a highly contagious and economically important viral infection of cattle, which leads to financial losses in the livestock industry of affected countries. Vaccination is the most effective control measure to prevent the disease. Heterologous sheep pox (SP) vaccine was used against LSD in Turkey. In this research, it was aimed to adapt SP Bakırköy vaccine strain attenuated in lamb kidney cells to Madin-Darby bovine kidney (MDBK) cells to provide better protection than commercial SP vaccine in cattle.
Materials and Methods:
To evaluate safety and efficacy of vaccines, while animals were immunized with 10 doses (104.75 50% tissue culture infectious dose [TCID50]) and 5 doses of SP vaccine (104 TCID50) produced in MDBK cells, others were immunized with commercial Penpox-M vaccine (103.9TCID50). Two cattle were kept as unvaccinated. At day 31 post-vaccination, all animals were challenged with the virulent LSD virus. Blood and swab samples were taken on certain days post-inoculation. Logarithmic differences challenge virus titers between vaccinated and unvaccinated animals were calculated.
Results:
The clinical sign was not observed in animals immunized with 10 doses of SP vaccine. The differences between the animals immunized with SP vaccine and control group was less than log 2.5 and the viremia occurred in immunized animals. The difference in titer was higher than log 2.5 in animals immunized with the Penpox-M, and viremia did not occur.
Conclusion
SP vaccine strain propagated in MDBK cells and can be used for immunization to prevent LSD infections. However, SP vaccine strain propagated in MDBK showed poor protection as compared to Penpox-M.

BACKGROUND/AIMS: We sought to examine whether the presence of gallstone disease (GD) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD) is associated with liver fibrosis and histological nonalcoholic steatohepatitis (NASH) score. METHODS: We included 441 Turkish patients with biopsy-proven NAFLD. GD was diagnosed in the presence of sonographic evidence of gallstones, echogenic material within the gallbladder with constant shadowing and little or no visualization of the gallbladder or absence of gallbladder at ultrasonography, coupled with a history of cholecystectomy. RESULTS: Fifty-four patients (12.2%) had GD (GD+ subjects). Compared with the GD- subjects, GD+ patients were older, had a higher body mass index and were more likely to be female and have metabolic syndrome. However, GD+ patients did not have a higher risk of advanced fibrosis or definite NASH on histology. After adjustment for potential confounding variables, the prevalence of GD in NAFLD patients was not associated with significant fibrosis (> or =2) (odds ratio [OR], 1.06; 95% confidence interval [CI], 0.53 to 2.21; p=0.68) or definite NASH (OR, 1.03; 95% CI, 0.495 to 2.12; p=0.84). CONCLUSIONS: The presence of GD is not independently associated with advanced fibrosis and definite NASH in adult Turkish patients with biopsy-proven NAFLD.

This study was carried out to describe clinical, gross and histopathological findings in the respiratory tract in chickens infected intranasally with A96 strain of infectious laryngotracheitis virus (ILTV). In addition, the presence of ILTV antigens in formalin-fixed and paraffin-embedded larynx and trachea tissues was investigated with the immunoperoxidase (IP) method in the infected chickens. At various days of viral infection, nares, larynx, trachea, lungs and air sacs tissue samples of the infected chickens were obtained and fixed with formalin and embedded in paraffin. The cross sections were stained with hematoxylineosin, and the larynx and trachea sections were also stained with the IP method. Mild rales and gasping were observed in only 4 of 35 chickens. The virus caused mild inflammatory changes in the respiratory tract. It was shown that clinical, gross and histopathological findings were not specific for differential diagnosis of the disease. However, ILTV antigens were detected by the IP method in formalin-fixed and paraffin-embedded larynx and trachea sections. These results revealed that the study use of the IP method might be useful for the diagnosis of ILTV infections with non-specific lesions.

Osteoblastomas are rare neoplasms of the spine. The majority of the spinal lesions arise from the posterior elements and involvement of the corpus is usually by extension through the pedicles. An extremely rare case of isolated C2 corpus osteoblastoma is presented herein. A 9-year-old boy who presented with neck pain and spasmodic torticollis was shown to have a lesion within the corpus of C2. He underwent surgery via an anterior cervical approach and the completely-resected mass was reported to be an osteoblastoma. The pain resolved immediately after surgery and he had radiologic assessments on a yearly basis. He was symptom-free 4 years post-operatively with benign radiologic findings. Although rare, an osteoblastoma should be considered in the differential diagnosis of neck pain and torticollis, especially in patients during the first two decades of life. The standard treatment for osteoblastomas is radical surgical excision because the recurrence rate is high following incomplete resection.

PURPOSE: Introducing the relationship between the surgical instruments used in modified radical mastectomy and wound complications is important for preventing and decreasing complications. This prospective randomized trial was designed to assess the impact of scalpel, electrocautery, and ultrasonic dissector usage on wound complications and tissue damage. METHODS: Eighty-two consecutive patients operated with mastectomy were studied. The postoperative time period needed for hemovac drainage, the amount and duration of seroma, infection, flap ecchymosis and necrosis rates were compared. Tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) levels in drainage fluids were determined to confirm the inflammatory response and tissue damage. RESULTS: The numbers of patients included in the scalpel, electrocautery and ultrasonic dissector groups were 27, 26, and 29, respectively. The groups were homogenous with respect to age, body mass index, stage, cormorbidities, breast volume and flap area. Operation time and the amount of bleeding were statistically higher in the scalpel group. The incidence of seroma was higher in the electrocautery group and arm mobilization had to be delayed in this group. There were no differences between groups with respect to hematoma, infection, ecchymosis, necrosis, hemovac drainage and the total and first 3 days of seroma volume. TNF-alpha and IL-6 levels were significantly higher in samples obtained from the drains of patients operated with electrocautery. CONCLUSION: Ultrasonic dissector decreases operation time by decreasing the amount of bleeding without increasing the seroma incidence. High cytokine levels in drainage fluids from patients operated with elecrocautery indicates that electrocautery induces more tissue damage and acute inflammatory response. Therefore, seroma, due to acute inflammatory response, was seen more frequently in the electrocautery group. Ultrasonic dissector coagulates protein by breaking hydrogen bonds which may close vascular and lymphatic channels more precisely. But, its actual preventive effect on seroma formation might be related to diminished inflammatory response.

STUDY DESIGN: A retrospective study investigating decrease in the nucleus pulposus signal intensity or disc height on magnetic resonance imaging (MRI) and disc degeneration. PURPOSE: Although a degenerated disc cannot self-regenerate, distraction or stabilization may provide suitable conditions for rehydration and possible regeneration. This study aimed to evaluate clinical outcomes and disc regeneration via MRI in a series of patients with degenerative disc disease (DDD) who underwent lumbar stabilization with a dynamic stabilization system (DSS). OVERVIEW OF LITERATURE: A dynamic system provides rehydration during early DDD. METHODS: Fifty-nine patients (mean age, 46.5 years) who undedwent stabilization with DSS for segmental instability (painful black disc) between 2004 and 2014 were retrospectively evaluated. All patients underwent MRI preoperatively and 12 months postoperatively. Intervertebral disc (IVD) degeneration grades at the implanted segment were categorized using the Pfirrmann classification system. Patients were followed for a mean of 6.4 years, and clinical outcomes were based on visual analog scale (VAS) and Oswestry disability index (ODI) scores. RESULTS: Significant improvements in back pain VAS and ODI scores from before surgery (7 and 68%, respectively) were reported at 6 (2.85 and 27.4%, respectively) and 12 months postoperatively (1.8 and 16.3%, respectively). Postoperative IVD changes were observed in 28 patients. Improvement was observed in 20 patients (34%), whereas progressive degeneration was observed in eight patients (13.5%). Thirty-one patients (52.5%) exhibited neither improvement nor progression. Single Pfirrmann grade improvements were observed in 29% of the patients and two-grade improvements were observed in 5%. CONCLUSIONS: Our observations support the theory that physiological movement and a balanced load distribution are necessary for disc regeneration. We conclude that DSS may decelerate the degeneration process and appears to facilitate regeneration.

OBJECTIVE: This study was undertaken in the belief that the atypical antipsychotic drug quetiapine could prevent apoptosis in the penumbra region following ischemia, taking into account findings that show 5-hydroxytryptamine-2 receptor blockers can prevent apoptosis. METHODS: We created 5 groups, each containing 6 animals. Nothing was done on the K-I group used for comparisons with the other groups to make sure adequate ischemia had been achieved. The K-II group was sacrificed on the 1st day after transient focal cerebral ischemia and the K-III group on the 3rd day. The D-I group was administered quetiapine following ischemia and sacrificed on the 1st day while the D-II group was administered quetiapine every day following the ischemia and sacrificed on the 3rd day. The samples were stained with the immunochemical TUNEL method and the number of apoptotic cells were counted. RESULTS: There was a significant difference between the first and third day control groups (K-II/K-III : p=0.004) and this indicates that apoptotic cell death increases with time. This increase was not encountered in the drug groups (D-I/D-II : p=1.00). Statistical analysis of immunohistochemical data revealed that quetiapine decreased the apoptotic cell death that normally increased with time. CONCLUSION: Quetiapine is already in clinical use and is a safe drug, in contrast to many substances that are used to prevent ischemia and are not normally used clinically. Our results and the literature data indicate that quetiapine could help both as a neuronal protector and to resolve neuropsychiatric problems caused by the ischemia in cerebral ischemia cases.
