Biochemical and cytologic analysis of cystic contents in benign non-parasitic symptomatic hepatic cysts before and after ethanol sclerotherapy

Purpose: To examine the fluid of liver cysts by cytologic and biochemical analysis before and after ethanol sclerotherapy in order to explore the etiology of cystic fluid reproduction after sclerotherapy.

Material and Methods: The contents of 11 cysts in 11 patients were examined on the day of sclerotherapy, and 2-8 (mean 4.5) days later, and analysed for cytologic and biochemical parameters.

Results: Cytologic signs of acute or subacute inflammatory reaction were absent before and present in all cysts after sclerotherapy. Biochemical parameters reflecting the acute inflammatory reaction (CRP, orosomucoid and haptoglobine), changes in capillary permeability (protein, albumin), and the cystic epithelial function (bilirubin, alkaline phosphatase) were significantly elevated after sclerotherapy.

Conclusion: The post-sclerotherapy fluid production is probably due to an inflammatory reaction. This may explain the success of performing sclerotherapy in one single session.

Changes in pelvic alignment in a woman before and after childbirth,using three-dimensional pelvic models based on magnetic resonance imaging: A longitudinal observation case report

3-dimensional pelvic models based on magnetic resonance images (MRI) can be used to investigate accuracy and specifics of changing pelvic alignment during pregnancy and after childbirth. Few studies have investigated changes of pelvic alignment during pregnancy and after childbirth using three-dimensional pelvic models. This case report documents the changes of pelvic alignment during late pregnancy and after childbirth using MRI-based three-dimensional (3D) pelvic models. This was a longitudinal observation case report. A woman was imaged with MRI at 28 and 39 gestational weeks, as well as 4 and 72 weeks after childbirth. Greater internal, anterior, and downward rotation of both innominates at week 39 was observed from that at gestation week 28. Decreased internal, anterior, and downward rotation of both innominates at week 4 after child birth was observed compared with that at gestation week 39. We report the first case in Japan of changes of pelvic alignment measured using an MRI-based 3D pelvic alignment model during pregnancy and after child birth. This case suggests that the small changes of pubic area and greater separation of anterior portions of sacroiliac joints. Internal, anterior, and downward rotation of both innominates was observed in a Japanese primipara woman having no pelvic pain.

Echinococcal cysts of the liver: A retrospective analysis of clinico-radiological findings and different therapeutic modalities

The clinico-radiological findings and management of 61 patients with proven hepatic echinococcal cysts (HEC) examined over the past 5 years were retrospectively analyzed. The sonography and computed tomography (CT) scan findings were studied before and after therapy. The indications, healing, and complications rates for each therapeutic modality were recorded. There is a predominance of HEC in adult females (female to male ratio, 1.77:1). The majority of patients complained of abdominal pain (39/61; 64.4%), and the majority of cysts were solitary (43/61; 70.5%), localized in the right lobe (47/61; 77.0%), and superficial (57/61; 93.4%). Few cysts were complicated by rupture, intraperitoneal (2/61; 3.2%), or intrabiliary (5/61; 8.2%). Medical treatment consisted of antihelmintic chemotherapy alone in eight patients with an adequate response in seven patients (7/8; 87.5%). Thirty-two patients had open or laparoscopic surgery with a cure rate of 50%. The other 50% had major complications requiring a further adjuvant therapy for a complete cure. Nine patients underwent percutaneous catheter ablation combined with adjuvant chemotherapy; healing was observed in eight patients (8/9; 88.8%). HEC are best treated by nonsurgical minimally invasive techniques combined with adjuvant antihelmintic chemotherapy, while surgery should be reserved for complicated HEC by intraperitoneal rupture.     

Effect of exergames on musculoskeletal pain: A systematic review and meta‐analysis

The main objective was to systematically review the scientific literature about the effects of exergame‐based interventions on musculoskeletal pain, as well as to provide directions for the clinical practice. A systematic search was conducted in four electronic databases following PRISMA guidelines. The inclusion criteria were as follows: (a) the subjects were suffering musculoskeletal pain, (b) the study was randomized controlled trial (RCT ), (c) intervention was based on exergames, (d) the article was written in English, and (e) the article was not an abstract or summary presented in a congress or conference. Risk of bias and quality of evidence were evaluated using the PED ro Scale and GRADE approach, respectively. A meta‐analysis was carried out to determine effect sizes. Seven studies were selected in the systematic review. The meta‐analysis included those six articles which reported means and SD before and after treatment and used a visual analog scale or a Numeric Pain Rating Scale. Four of the seven articles reported significant reduction in pain while the rest did not found any significant change in pain after the intervention. The overall effect size for pain was −0.51 (95% CI from −1.25 to 0.23) with large heterogeneity. Although four of the seven articles reported significant within‐group differences, zero was included in the CI of the overall effect size. Therefore, up‐to‐date there is not enough evidence to conclude that exergames improve musculoskeletal pain.

The active abduction view: A new maneuvre in the diagnosis of rotator cuff tears

The plain film views of the shoulder in the case of a fresh rotator cuff tear are usually normal. Reduction of the space between the under surface of the acromion process of the scapula and the humeral head occurs only in late, neglected cases. A new projection is described, the active abduction view of the shoulder, where in many patients with a complete rotator cuff tear the humeral head is closely apposed to the acromion, obliterating the subacromial space. In such a situation, the medial portion of the torn rotator cuff retracts during active abduction, allowing approximation of the two bones.     

A comparative roentgenographic analysis of the lumbar spine in male army recruits with and without lower back pain

AIM: To determine whether there is an association between lumbar spine radiographic findings and reported current and/or past lower back pain (LBP). MATERIALS AND METHODS: Four hundred and sixty-four age-matched (mean age 18 years+/-2 months) consecutive male army recruits were examined. Half of them had a history of episodes of LBP. An orthopaedic evaluation (including radiographs of the lumbar spine) is part of the routine medical examination for all military recruits. Two senior orthopaedic surgeons and one radiologist who performed the morphological measurements assessed the radiographs. RESULTS: We found an increased frequency of right-sided scoliosis, lumbar lordosis, sacral lumbarization, wedge vertebra, bilateral spondylolysis of L5 and/or a sagittal diameter of less than 12 mm among the recruits with LBP. No such association was found with spina bifida, left-sided scoliosis, hemi-lumbarization, sacralization and hemi-sacralization, Schmorl's nodules or mild degenerative changes. CONCLUSION: Given that radiographic screening shows that LBP is more common in those with spinal deformity it may be a reasonable means of predicting which individuals are more likely to develop LBP.

Comparison of cardiac function before and after Micra implantation using pool scintigraphy and myocardial work: A case report

Leadless pacemakers, specifically Micra (Medtronic), have recently become a preferred alternative to transvenous pacemakers for use in bradyarrhythmia. Problems with conventional transvenous pacemakers include wound infection, lead disconnection, and tricuspid valve dysfunction. While Micra has the advantage of not being associated with the aforementioned complications, there have been reports of cardiac injury during Micra implantation, which have raised safety concerns. Many reports have evaluated Micra safety, but its effect on cardiac function remains unclear. In an 85-year-old man with bradycardic atrial fibrillation, a heart rate of approximately 35 bpm, and symptoms of dizziness, we analyzed ventricular workload, ejection fraction of the left and right ventricles, and inter/intraventricular synchrony using cardiac blood pool scintigraphy and myocardial work. Micra was successfully implanted into the right ventricular septum via the left femoral vein. A follow-up, 2 days later, showed no major complications associated with Micra pacing threshold and impedance. At this time, there was no apparent worsening of heart failure. Micra implantation for bradycardic atrial fibrillation has the potential to improve left ventricular work efficiency without the loss of ventricular synchrony.
