This case series' purpose is to review a referral center's experience with complications from mesh kits. A chart review of 12 patients who presented with complications associated with transvaginal mesh kit procedures was performed. All patients underwent complete surgical removal of the mesh to treat mesh exposure, pain, or vaginal bleeding/discharge followed by an anterior or posterior repair. The mean follow-up time after surgery was 3.4 months. Eight of 12 patients had mesh that had formed a fibrotic band. Six of 12 patients had complete resolution of pain. Of the nine patients with mesh exposure, all required significant resection of the vaginal wall. No further mesh exposure occurred. The use of transvaginal mesh kits may cause previously undescribed complications such as pelvic/vaginal pain or large extrusions requiring complete removal. Removal of all mesh except the arms may cure or significantly improve these problems.

Coriander (Coriandrum sativum L.) is grown as a spice crop all over the world. The seeds have been used to treat indigestion, diabetes, rheumatism and pain in the joints. In the present study, an ethanol extract of the seeds was investigated for effects on insulin release from the pancreatic beta cells in streptozotocin-induced diabetic rats. Blood samples were drawn from the retro-orbital sinus before and 1.5, 3 and 5 h after administration of the seed extract. Serum glucose levels were determined by the glucose oxidase method. To determine the insulin releasing activity, after extract treatment the animals were anaesthetized by diethyl ether, the pancreas was excised, fixed in 10% formaldehyde and embedded in paraffin for sectioning. Pancreatic sections of 5 microm were processed for examination of insulin-releasing activity using an immunocytochemistry kit. The results showed that administration of the ethanol extract (200 and 250 mg/kg, i.p.) exhibited a significant reduction in serum glucose. Administration of streptozotocin decreased the number of beta cells with insulin secretory activity in comparison with intact rats, but treatment with the coriander seed extract (200 mg/kg) increased significantly the activity of the beta cells in comparison with the diabetic control rats. The extract decreased serum glucose in streptozotocin-induced diabetic rats and increased insulin release from the beta cells of the pancreas.

Nitric oxide plays an important role in the pathogenesis of migraine as well as tension-type headache. Studies suggest that the expression of molecules involved in the pathogenesis of headache, i.e., nitric oxide and interleukin, is influenced by apolipoprotein E (APOE) and is gene specific. Hence, we hypothesized that APOE polymorphism may be associated with migraine as well as tension-type headache.The study sample comprised of three groups: migraineurs, tension-type headache subjects as well as a healthy control group. A total of 50 subjects in each group were included after screening for the inclusion and exclusion criteria. None of the subjects was a blood relative of any other subject included in the present study. Their venous blood was drawn and stored at -20 degrees C. Genomic DNA extraction was performed with a commercial kit and simple sequence-specific primer PCR was performed to assess the APOE polymorphism. Data were analyzed with the help of SPSS V11.0 for Windows. chi(2) test and logistic regression analysis were run. The results of the study showed that APOE epsilon2 gene increases the risk of migraine as compared to the control group and the tension-type headache group (OR=4.85; 95% CI=1.92-12.72; P<0.001 and OR=2.31; 95% CI=1.08-4.94; P=0.01, respectively). Interestingly, APOE epsilon4 gene was protective against migraine as well as tension-type headache. This study shows that APOE epsilon2 gene increases the risk of migraine, while APOE epsilon4 gene is protective against migraine and tension-type headache. Further research is required to confirm the findings of the present study in a larger sample and to elucidate the role of APOE polymorphism in headache.

Understanding the occurrence and management of mesh kit complications has become increasingly important. A 54-year-old woman presented to our tertiary care center with complaints of constant perineal pain, and copious, foul-smelling vaginal discharge after anterior and posterior placement of a synthetic mesh and mid-urethral sling 3 months earlier. She was found to have two vaginocutaneous sinus tracts (to the left ischiorectal fossa and to the left labia majora), as well as bilateral abscess cavities within the ischiorectal fossae. The posterior mesh was completely excised, the tracts were opened, and the wound was packed and allowed to heal by secondary intention.

Calcitonin gene-related peptide (CGRP) is known to increase during acute attack of migraine and tension type headache (TTH). However, its concentration during inter-ictal period is not known. This may help us to understand the pathophysiology of these headaches. The objectives of this study are to find out the concentration of CGRP in plasma during inter-ictal period among migraineurs and TTH and to compare it with control group through cross-sectional study from headache clinic of a tertiary centre. Study sample comprised of three groups: migraineurs, TTH subjects as well as a healthy control group. Fifty subjects in each group were included after screening for the respective inclusion criteria and exclusion criteria. None of the subjects was blood relatives of other subject. Their venous blood was drawn and plasma was separated to be kept at -70 degrees C. CGRP was analysed with commercially available ELISA kit. Data were analysed with the help of SPSS V 11.0 for Windows. Chi-square, independent sample t test and one-way ANOVA with post hoc Tukey and univariate regression were performed. Plasma CGRP concentration was not different among three diagnostic groups (F = 0.78; P = 0.49). Similarly, plasma CGRP concentration was not different among episodic TTH and chronic TTH groups (t = 0.32; P = 0.97) and comparison of episodic and chronic migraine groups also revealed similar results in this study (1.14 vs. 0.94 ng/ml; P = 0.23). The presence of aura did not affect the inter-ictal CGRP levels among migraineurs (F = 0.16; P = 0.85). In conclusion, this study suggests that migraine and TTH could be episodic disorders and subjects have comparable CGRP levels during inter-ictal period.

The Unified Parkinson's Disease Rating Scale (UPDRS) is currently used to assess Parkinson's disease, and is a key method for determining the progression of disease based on the gross findings of patients. However, this method cannot quantify the extent of disease of patients, which means the administration of drugs cannot be determined on a real-time basis. Thalamotomy also causes discomfort and pain to the patients, and adversely affects treatment as it is performed following the onset of symptoms. Accordingly, the dopamine concentration, which is one of the key factors in determining this disease, needs to be detected quantitatively at ordinary times. Hence, the development of a bio-kit or a bio-sensor is essential for effectively prescribing the correct dopamine concentration in a customizable manner. In this study, the effect of dopamine level on this phenomenon was observed using the Forster resonance energy transfer (FRET) phenomenon generated between a donor and acceptor. By confirming the photoluminescence (PL) and lifetime data, it was demonstrated that the degree of energy transfer increased with increasing dopamine concentration. To apply this phenomenon to an optical sensor, a glass surface was modified with a quantum dot (QD)-encapsulated dendrimer, and analyzed using the contact angle and ATR-FTIR. The topology of surface was determined by an atomic force microscope (AFM).

Thoracoscopic surgery without or with video assistance (VATS) is simpler and easier to learn as it seems to be. Potential benefits of the procedure in rural surgical environment are outlined while basic requirements and limitations are listed. Thoracoscopy kit, thoracotomy tray at hand, patient monitoring, proper drainage system, pain control and access to chest physiotherapy are the basic requirements. Having headlight, bronchoscope, Ligasure and mechanical staplers offer clear advantages but they are not indispensable. Exploration and evacuation of pleural space, pleurodesis, surgery for Stage I and II thoracic empyema are evidenced fields of VATS procedures. Some of the cases can be performed under controlled local anesthesia. Acute chest trauma cannot be recommended for VATS treatment. Lung cancer is out of the scope of rural surgery.

Intra-articular hyaluronic acid has been used in treatment of patients with knee osteoarthritis. Though its effect on pain has been well studied, it is not clear how it affects the articular cartilage. This is a preliminary study to evaluate the kinetics of urinary collagen type-II C-telopeptide (CTX-II) as a biomarker of collagen breakdown in response to intra-articular hyaluronic acid injection in patients with symptomatic knee osteoarthritis. Intra-articular injections of hyaluronan were administered to ten patients with symptomatic knee osteoarthritis. Urine collection for urinary CTX-II was obtained at baseline, before each injection and once every other week for a total of 6 months. Urine CTX-II was measured using a CartiLaps(c) ELISA kit. There was a statistically significant increase (p = 0.0136) in CTX-II a week after the third intra-articular injection of hyaluronic acid (6,216 ng/mmol +/- 4,428) compared with baseline (2,233 ng/mmol +/- 1,220). This increase in CTX-II was sustained throughout the entire 6 months follow-up period (repeated measures ANOVA, p < 0.015). This is the first study of changes in an osteoarthritis biomarker after intra-articular hyaluronic acid injections in patients with symptomatic knee osteoarthritis. Contrary to our initial hypothesis that CTX-II levels should decrease after intra-articular hyaluronic acid injections, we found a significant increase in urinary CTX-II levels that was sustained throughout the study. These observations suggest that intra-articular hyaluronic acid injections may accelerate cartilage breakdown in patients with symptomatic knee osteoarthritis. The responsible mechanisms are unknown and warrant further study.

Frequently, it is important to ascertain whether a molecule that is involved in one model of pain is also involved in other models of pain. Similarly, it may be important to determine whether a molecule involved in nociception in one tissue is also expressed in other tissues and to ascertain the degree of enrichment. Additionally, before initiating a complex set of experiments or purchasing an expensive immunoassay kit, it may be useful to obtain initial supporting evidence to justify the time and money. Is the transcript for the target receptor, protein, or peptide precursor present in, for example, the dorsal root ganglion? And, if present, how abundant is it? Here is where the power of PCR can be applied to obtain a quick but informative answer. In this chapter, we mainly detail the use of gel-based RT-PCR and also provide suggestions on tissue dissection and interpretation of results. The use of gel-based RT-PCR can address many of the questions of abundance or tissue specificity with a minimum of expense and time.

The palliation of pain due to bone metastases using targeted compounds containing beta-emitters such as rhenium-188 ((188)Re) is an accepted and effective form of treatment. Here, we describe the efficient synthesis and preclinical evaluation of (188)Re(CO)(3)-dipicolylamine(DPA)-alendronate, a novel bifunctional bisphosphonate for the palliative treatment of bone metastases. (188)Re(CO)(3)-DPA-alendronate can be easily synthesized with high specific activities and yields (18.8 GBq/mg, radiochemical yield > or =96%) in two steps using kit-based methodology, and in contrast with the clinically approved bisphosphonate (186/188)Re-HEDP, it forms inert, single species that have been well-characterized. In vivo imaging and biodistribution studies demonstrate that (188)Re(CO)(3)-DPA-alendronate is superior to (188)Re-HEDP in targeting and accumulating in areas of high metabolic bone activity while having low soft-tissue uptake. In addition to these studies, a simple and convenient new method for purifying its precursor, fac-[(188)Re(CO)(3)(H(2)O)(3)](+), is described.
