Thumb Carpometacarpal

Purpose: To describe the biomechanical changes seen after thumb carpometacarpal (CMC) fusion with distal scaphoid excision (DSE), a surgical technique used for pantrapezial disease in high-demand individuals. Methods: A cadaveric study with 13 fresh-frozen cadaveric specimens was conducted. Fluoroscopic measurements in posteroanterior (PA) and lateral planes were performed. Thumb CMC fusion was then simulated. The same images were taken after fusion. The distal scaphoid was excised, and the measurements were obtained again. The angle between the index finger and thumb metacarpals was recorded. Statistical analysis was performed using Wilcoxon signed rank test. Results: The mean arcs of motion in the PA plane pre-fusion, post-fusion, and post-fusion with DSE were 48.5°, 25.1°, and 34.6°, respectively. An increase in arc of 9.5° was obtained after DSE compared with thumb CMC fusion alone. The mean arcs of motion in the lateral plane pre-fusion, post-fusion, and post-fusion with DSE were 53.4°, 22.4°, and 33.6°, respectively. A statistically significant increase in arc of motion of 11.2° in the lateral plane was obtained after DSE compared with thumb CMC fusion alone. This was a 20% and 21% increase in pre-fusion range of motion in the PA and lateral planes, respectively, from fusion alone compared with fusion and DSE. Conclusions: Thumb CMC fusion combined with DSE maintains motion lost in simple CMC arthrodesis.

Rotation Stress

Background: In this cadaveric study, a new “torque test” (TT) stressing the fibula posterolaterally under direct visualization was compared with the classical external rotation stress test (ERT) and lateral stress test (LST). Methods: The anteroinferior tibiofibular ligament (AiTFL), the interosseous membrane (IOM), and the posteroinferior tibiofibular ligament (PiTFL) were sectioned sequentially on 10 fresh-frozen human ankles. At each stage of dissection, instability was assessed using the LST, ERT, and TT under direct visualization. Anatomical tibiofibular diastasis measurements were taken directly on cadavers and compared using the Wilcoxon signed rank test. Results: All 3 tests showed statistically significant motion in the syndesmosis when at least 2 ligaments were sectioned. The mean increase across diastasis with a 2-ligament section was 3.0 mm ( P = .005), 3.2 mm ( P = .005), and 4.8 mm ( P = .005) for the LST, ERT, and TT, respectively. The largest mean increase in diastasis was obtained with a complete injury using the TT and was 6.2 mm ( P = .008). With the TT, a 3.5-mm tibiofibular diastasis was 90% sensitive and 100% specific when 2 or more syndesmotic ligaments were sectioned. Conclusion: The TT was a more sensitive and specific tool for detecting syndesmosis instability than classic LST and ERT. Clinical relevance: Stressing the fibula in a posterolateral direction created a larger distal tibiofibular diastasis, which would be easier to detect in the intraoperative setting. The TT was more sensitive and specific to detecting a 2-ligament syndesmotic injury than the classic test and required less force to perform.

The aim of this study is to investigate 8 weeks Thera-Band trainings' effects on male swimmers' 100 m freestyle swimming performance.The study group is created by 20 (n = 20) licenced male athletes that had trained at least 3 days in a week and have been active in swimming sport at least 3 years in Gebze Genclerbirligi Swimming Club 20 (n = 20). Athletes were divided into experiment group (n = 10) and control group (n = 10) randomly. Training programme was applied to the study group for 55-60 minutes for 3 days on alternate days and times when the club does not have swimming training. 12 different Thera-Band trainings were applied for 40-45 mins and each set was 15 minutes.Mann-Whitney U test was used to analyze differences between groups and Wilcoxon signed rank test was applied for analyzing the differences of intra-groups. SPSS 21.0 Statistics package software was used for statistical analyzes. The results show that there are no significantly differences between experimental group's and control group's post test results. (p>0.05). Statistically significant differences are found as a result of intra-group comparison of the experimental group's pre-test and post-test results (p<0.05).Depending on the results obtained after reviewing the literature, it can be concluded that Thera-Band training is effective on the performance improvement of swimmers aged 13-15 years.

Forceps biopsies of airway lesions have variable yields. The yield increases when combining techniques in order to collect more material. With the use of cryotherapy probes (cryobiopsy) larger specimens can be obtained, resulting in an increase in the diagnostic yield. However, the utility and safety of cryobiopsy with all types of lesions, including flat mucosal lesions, is not established.Aims. Demonstrate the utility/safety of cryobiopsy versus forceps biopsy to sample exophytic and flat airway lesions.Settings and Design. Teaching hospital-based retrospective analysis.Methods. Retrospective analysis of patients undergoing cryobiopsies (singly or combined with forceps biopsies) from August 2008 through August 2010.Statistical Analysis. Wilcoxon signed-rank test.Results. The comparative analysis of 22 patients with cryobiopsy and forceps biopsy of the same lesion showed the mean volumes of material obtained with cryobiopsy were significantly larger (0.696 cm3versus 0.0373 cm3,P=0.0014). Of 31 cryobiopsies performed, one had minor bleeding. Cryopbiopsy allowed sampling of exophytic and flat lesions that were located centrally or distally. Cryobiopsies were shown to be safe, free of artifact, and provided a diagnostic yield of 96.77%.Conclusions. Cryobiopsy allows safe sampling of exophytic and flat airway lesions, with larger specimens, excellent tissue preservation and high diagnostic accuracy.

The impregnation of knitted Dacron grafts with biodegradable protein removes the need for preclotting at implantation. The effect of such impregnation on the thrombogenic potential of these prostheses is, however, unknown. We have compared the early thrombogenicity of two impregnated knitted Dacron grafts - Hemashield ( collagen-impregnated Dacron, Meadox) and Gelseal (gelatin-impregnated Dacron, Vascutek) -with conventionally preclotted knitted Dacron in an artificial circulation. Fresh, heparinised human blood, containing 111Indium-labelled platelets, was circulated around identical twin circuits of silicone tubing by a Sarns roller pump at 180 ml/min and 120 mmHg. Into each circuit a different 15 cm × 8 mm type of graft material was mounted. Changes in platelet count, platelet aggregation to collagen, plasma haemoglobin and blood radioactivity were recorded and after 60 minutes of perfusion each graft was sectioned and counted for radioactivity prior to scanning electron microscopy (SEM) of the luminal surface. The mean graft radioactivity divided by the mean blood radioactivity yields a Graft Activity Index (GAI) allowing comparison of platelet deposition and thus thrombogenicity.RESULTS: (mean ± s.e.m.) 8 examples of each graftSEM confirmed these findings with preclotted Dacron having the highest platelet deposition. Both impregnated grafts produced significant early haemolysis within 4 minutes of blood contact. Our findings indicate that the early thrombogenicity of these impregnated grafts is significantly less than conventionally preclotted Dacron, (p< 0.01, Wilcoxon signed rank test), despite the early haemolytic phenomenon and that Hemashield grafts are less thrombogenic than Gelseal grafts. (p<0.05, Wilcoxon signed rank test)

IntroductionAnxiety and mood disorders are common in adolescence and predict poor mental health outcomes and low quality of life in adulthood. Although early intervention seems to be critical, dropouts in the early stages of treatment are frequent and associated with low insight and severe symptoms. Therefore, a diagnostic assessment phase aimed to increase insight and early reduce symptoms appears to be essential in adolescents.ObjectivesThe objective of this study is to demonstrate that the diagnostic method Cooperative Assessment is able to early reduce symptoms in adolescents with anxiety and mood disorders.MethodsA sample of 88 patients, aged 14–19 years were included. All were recruited at the first visit and evaluated with the Cooperative Assessment. This manualized procedure was created from principles of collaborative and therapeutic assessment and aim to involve the patient in a co-developed diagnosis thorough the collaborative use of test results. Patients were evaluated before (T0), in the middle (T1) and after (T2) the assessment using CGI, GAF, HAM-A, HAM-D and MRS scales.ResultsEighty-eight adolescents, 56.8% females, diagnosed with anxiety (47.7%) and mood disorders (52.3%) completed the protocol. HAM-A, HAM-D, MRS, CGI and GAF significantly improved at T1 and T2 with respect to T0 (T0: HAM-A 17.31 ± 8.22; HAM-D 16.97 ± 8.37; MRS5.78 ± 6.17; GAF 59.3 ± 11.06; CGI 3.63 ± 1.35; T2: HAM-A 11.41 ± 6.82; HAM-D 11.1 ± 6.91; MRS3.82 ± 3.87; GAF 67.5 ± 10.76; CGI 3.03 ± 1.26; P < 0.001; Wilcoxon signed-rank test for repeated measures).ConclusionsCooperative assessment is able to early improve symptoms in adolescents with mood and anxiety disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Breast Care

Breastfeeding is a normal process following childbirth. However, post partum mothers often complain several problems during breastfeeding. A problem that is often complained of by post partum mothers is the lack of breast milk supply. The lack of breast milk production will interfere with the process of breastfeeding, which is one of the causing factors as to why certain mothers do not exclusively breastfeed. To find out the effect of breast care and oxytocin massage on increasing milk production in post partum mothers. This research uses a quasi-experimental design. The population in this study were all primiparous post partum mothers with lactation period of 0-7 days. A total of 20 mothers participated in this study and was divided into two groups namely the treatment group and the comparison group. The samples were obtained using purposive sampling. There are independent variables (breast care and oxytocin massage) and dependent variables (milk production). Data collection was performed using a questionnaire, then analyzed using the test Wilcoxon Signed Rank Test and Mann Whitney Test. Wilcoxon Signed Rank Test Results of breast milk production of (p = 0.003) in the treatment group, while in the comparison group the breast milk production was (p = 0.014). The Mann Whitney Test results show that p = 0.004. It can be concluded that breast care and oxytocin massage effectively increase the milk production of post partum mothers. The therapy is recommended for health professionals to apply breast care and oxytocin massage to increase the milk production of post partum mothers who have less milk production. Combination of breast care and oxytocin massage have more effective benefits in increasing the breast milk production of postpartum mothers.

ABSTRACT The fourth-generation QuantiFERON test for tuberculosis infection, QuantiFERON-TB Gold Plus (QFT-Plus) has replaced the earlier version, QuantiFERON-TB Gold In-Tube (QFT-GIT). A clinical need exists for information about agreement between QFT-Plus and other tests. We conducted this study to assess agreement of test results for QFT-Plus with those of QuantiFERON-TB Gold In-Tube (QFT-GIT), T-SPOT.TB (T-SPOT), and the tuberculin skin test (TST). Persons at high risk of latent tuberculosis infection (LTBI) and/or progression to tuberculosis (TB) disease were enrolled at the 10 sites of the Tuberculosis Epidemiologic Studies Consortium from October 2016 through May 2017; each participant received all four tests. Cohen’s kappa (κ) and Wilcoxon signed-rank test compared qualitative and quantitative results of QFT-Plus with the other tests. Test results for 506 participants showed 94% agreement between QFT-Plus and QFT-GIT, with 19% positive and 75% negative results. When the tests disagreed, it was most often in the direction of QFT-GIT negative/QFT-Plus positive. QFT-Plus had similar concordance as QFT-GIT with TST (77% and 77%, respectively) and T-SPOT (92% and 91%, respectively). The study showed high agreement between QFT-GIT and QFT-Plus in a direct comparison. Both tests had similar agreement with TST and T-SPOT.

Abstract Introduction: The Trunk-Pelvis-Hip Angle (TPHA) test is used for assessing the mobility of lumbo-pelvic-hip complex. The aim of the research was to assess the intraobserver reliability of the TPHA test in girls with and without idiopathic scoliosis and to compare the test values obtained by the girls in both groups. Material and methods: The research included girls without scoliosis and girls with double idiopathic scoliosis aged 8-16. The trunk-pelvis-hip angle was measured three times on each body side within one session. Statistical analysis was performed with the use of ANOVA intraclass correlation coefficient for dependent groups, Kolmogorov-Smirnov test as well as non-parametric Wilcoxon signed-rank test for dependent groups and Mann-Whitney U test for independent groups. Results: The research included 49 healthy girls (aged 11.8 ± SD 2.5 years) and 49 girls with double idiopathic scoliosis (aged 12.7 ± SD 2.6 years; Cobb angle Th 27.7° ± SD 13.4° and L Cobb 25.8° ± SD 10.5°). The intraobserver reliability for the TPHA measurements was very high (ICC>0.85). In both groups the left-side TPHA value was significantly higher than the right-side value (p=0.001). The TPHA range of motion on the right side of the body was more limited in the scoliotic girls than in the healthy ones (p=0.001). Conclusions: The TPHA test is a reliable means of assessing mobility in the lumbo-pelvic-hip complex in girls by one observer. The asymmetry of movements in the lumbo-pelvic-hip complex in healthy girls needs to be observed since it may constitute one of the factors predisposing to scoliosis which limits spine rotation range of motion. The TPHA test needs further research.

AIM: To assess the effectiveness of core vitrectomy-phacoemulsification-intraocular lens (IOL) implantation-capsulo-hyaloidotomy in treating phakic eye at least 1mo after the onset of malignant glaucoma. METHODS: A retrospective analysis were performed on malignant glaucoma patients treated in Zhongshan Ophthalmic Center between 2016 and 2018. Demographic and clinical data were described. The preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), number of IOP-lowering medications used, and anterior chamber depth (ACD) of the case series were compared by Wilcoxon signed-rank test. RESULTS: Thirteen phakic eyes with long time intervals between onset and surgery were identified in this case series. Core vitrectomy-phacoemulsification-IOL implantation-capsulo-hyaloidotomy reduced the IOP (P=0.046) and the number of IOP-lowering medications used (P=0.004), deepened the ACD (P=0.005). Complete success was achieved in 38.5% of the eyes, and anatomical success was achieved in 100% of the eyes without any recurrence. The only postoperative complication observed is corneal endothelial decompensation. It occurred in two cases. CONCLUSION: Core vitrectomy-phacoemulsification-IOL implantation-capsulo-hyaloidotomy is safe and effective for treatment of long onset phakic malignant glaucoma.
