Management of benign ovarian cysts by a novel, gasless, single-incision laparoscopic technique: keyless abdominal rope-lifting surgery (KARS)

Background

To find the most efficacious method to minimize the side effects and maximize the advantages of laparoscopic surgery, this study aimed to define and document a gasless, single-incision abdominal access technique for the management of benign ovarian cysts.

Methods

During a 1½ year period, 55 women underwent surgery for a benign ovarian cyst. Conventional carbon dioxide (CO₂) laparoscopy was used for 33 of the women, and 22 of the women underwent a novel, gasless, single-incision laparoscopic surgery. An abdominal access pathway through a single intraabdominal incision was used to place transabdominal sutures that elevated the abdominal wall, and the operations were performed through the intra-umbilical entry without the use of trocars. Thus, the new technique was called keyless abdominal rope-lifting surgery (KARS). Two operative groups were compared to assess the feasibility of the new technique.

Results

All the operations could be performed by KARS without conversion to CO₂ laparoscopy or laparotomy. However, for two patients in the conventional laparoscopy group, minilaparotomy had to be performed for tissue retrieval. Although the two techniques had many similar results, the total operative times and the abdominal access times in the KARS group were significantly longer than in the conventional laparoscopy group (p < 0.05). Simple oral analgesics were adequate for postoperative pain relief in both groups.

Conclusions

The KARS technique is a gasless, single-incision laparoscopic procedure that can be performed safely and effectively in terms of cosmesis, postoperative pain, and fertility preservation for the management of benign adnexal pathologies.     

Acute emergency tibialization of the fibula: reconstruction of a massive tibial defect in a type IIIC open fracture

Gustilo type IIIC open fractures of the tibia are high-energy injuries necessitating long treatment periods and usually multiple surgical procedures and eventually resulting in high morbidity rates and even amputations. We present here a case involving a type IIIC open tibial fracture with massive loss of the entire tibial diaphysis, which we treated by performing acute tibialization of the fibula after revascularization of the posterior tibial artery in a single-stage emergency operation.     

Sciatic nerve compression by an extrapelvic cyst secondary to wear debris after a cementless total hip arthroplasty: A case report and literature review

INTRODUCTIONPolyethylene (PE) wear debris after total hip arthroplasty (THA) may cause formation of a soft tissue mass due to inflammatory reaction. To the best of our knowledge we report the first case in whom the diagnosis was made after examination of the hip, pelvis and lumbar spine with detailed radiological methods and the plain radiographs showed no signs of loosening of the THA.PRESENTATION OF CASEWe report a 52 years-old woman who presented with a cyst causing sciatic irritation in her gluteal region due to wear debris after THA. Magnetic resonance imaging (MRI) was useful in detecting the cyst. Resolution of the cyst occured after subtotal cystectomy and revision of the acetabular components.DISCUSSIONAlthough plain radiographs can show signs of the underlying pathology; such as osteolysis, loosening of the components and wear of the PE liner, they are unable to detect cystic lesions. Cystic lesions may be an early sign of wear debris.CONCLUSIONThis case shows us that sciatic neuropathy with no evidence of nerve root impingement on lumbar MRI in a patient with THA requires also examination of the hip and pelvis with detailed radiological methods, such as MRI, in addition to plain radiography. Removal of the source of debris via revision surgery following subtotal cystectomy leads to the resolution of the remaining portion of the cyst and also relief of the symptoms of sciatic nerve compression.     

Neutrophil/lymphocyte ratio is associated with thromboembolic stroke in patients with non-valvular atrial fibrillation

BackgroundNeutrophil/lymphocyte ratio (NLR) has been associated with poor outcomes in patients with cardiovascular diseases. However, little is known about the role of NLR in patients with thromboembolic stroke due to atrial fibrillation (AF). We aimed to compare the NLR ratios between non-valvular AF patients with or without thromboembolic stroke.MethodsA total of 126 non-valvular AF patients with or without stroke were included in the study; 126 consecutive patients (52 males and 74 females), mean age, 70 ± 10.2 years old. No patient had a recent history of an acute infection or an inflammatory disease. Baseline NLR was measured by dividing neutrophil count to lymphocyte count. WBC count > 12.000 cells per μL or < 4.000 cells per μL and high body temperature > 38 º are excluded from the study.ResultsMean NLR was significantly higher among persons with stroke compared to individuals without a stroke (5.6 ± 3.4 vs. 3.1 ± 2.1, p = 0.001). There were no significant differences in RDW levels between the two groups (p > 0.05). HAS-BLED and CHADS₂ scores were significantly higher in the stroke group.ConclusionHigher NLR, an emerging marker of inflammation, is associated with thromboembolic stroke in non-valvular AF patients.     

Expression analysis and clinical correlation of aquaporin 1 and 4 genes in human hippocampal sclerosis

Mesial temporal sclerosis (MTS) is the most frequent cause of drug resistant symptomatic partial epilepsy. The mechanism and genetic background of this unique pathology are not well understood. Aquaporins (AQP) are regulators of water homeostasis in the brain and are expressed in the human hippocampus. We explored the role of AQP genes in the pathogenetic mechanisms of MTS through an evaluation of gene expression in surgically removed human brain tissue. We analyzed AQP1 and 4 mRNA levels by quantitative real-time polymerase chain reaction and normalized to ABL and cyclophilin genes, followed by immunohistochemistry for AQP4. Relative expressions were calculated according to the delta Ct method and the results were compared using the Mann-Whitney U test. Brain specimens of 23 patients with epilepsy who had undergone surgery for MTS and seven control autopsy specimens were investigated. Clinical findings were concordant with previous studies and 61% of the patients were seizure-free in the postoperative period. AQP1 and 4 gene expression levels did not differ between MTS patients and control groups. Immunofluorescence analysis of AQP4 supported the expression results, showing no difference. Previous studies have reported contradictory results about the expression levels of AQP in MTS. To our knowledge, only one study has suggested upregulation whereas the other indicated downregulation of perivascular AQP4. Our study did not support these findings and may rule out the involvement of AQP in human MTS.     

The evaluation of metacognitive beliefs and emotion recognition in panic disorder and generalized anxiety disorder: effects on symptoms and comparison with healthy control

Abstract

Background: The impairments in metacognitive functions and emotion recognition are considered as liable factors in anxiety disorders.

Aims: The better understanding of these cognitive abilities might lead to develop more accurate treatment methods for patients who suffer from anxiety.

Methods: Forty-four patients with panic disorder (PD), 37 individuals with generalized anxiety disorder (GAD) and 44 healthy control (HC) were participated in our study. Metacognition questionnaire-30 (MCQ-30), Reading The Mind From The Eyes Test and symptom severity tests were administered.

Results: Statistical analyses estimated the dysfunctional metacognitive beliefs and disrupted emotion recognition in patients relative to HC. The ‘need to control thoughts’ aspect of metacognitive beliefs was accounted for symptom severity in GAD. Improper metacognitive beliefs were significantly predicted the PD and GAD. In addition, impoverished emotion recognition predicted the GAD.

Conclusions: Our study revealed the role of inconvenient metacognitive beliefs and distorted emotion recognition in PD and GAD. These findings might facilitate the treatment management in cognitive therapies of anxiety disorders via pointing out more reasonable targets across improper cognitive fields.     

Ultrasonographic evaluation of the femoral cartilage thickness in patients with chronic renal failure

Objective To investigate the effects of chronic renal failure (CRF) on the distal femoral cartilage thickness by using ultrasonography and to determine the relationship between cartilage thickness and certain disease-related parameters. Design Fifty-seven CRF patients (41 male and 16 female) (mean [SD] age, 44.7 [12.1] years) and 60 healthy controls (41 male and 19 female) (mean [SD] age, 43.5 [13.3] years) were enrolled in this study. Demographic and clinical characteristics were recorded. Cartilage thickness measurements were taken from the medial and lateral condyles, and intercondylar areas of both knees. Results Groups were similar in terms of age, weight, height, body mass index and gender (all p>0.05). The mean cartilage thickness was found to be less in CRF patients than in controls (statistically significant for medial condyles and intercondylar areas both in right and the left knees [all p<0.05]). Cartilage thickness showed no correlation with eGFR, and with the levels of serum urea, creatinine, calcium, magnesium, phosphor, hemoglobin, uric acid and as well as steroid use (all p>0.05) in CRF patients. Conclusion In the light of our findings, we imply that patients with CRF have thinner femoral cartilage than healthy controls. This result may support the view that patients with CRF are at increased risk for developing early knee osteoarthritis. Last but not least, clinicians should be aware of the importance of rehabilitation strategies aimed at decreasing onset and progression of knee osteoarthritis in patients with CRF.
