Developmental dysplasia of the hip (DDH) is a term that incorporates a spectrum of disorders of the hip, ranging from mild dysplasia to complete irreducible hip dislocation. 1 In Denmark, a combination of universal clinical screening and selective ultrasound screening for DDH is implemented. Official national guidelines recommend a clinical hip examination by a midwife after birth which is repeated at a 5-week follow up by a general practitioner. 2 In supplement to the nationally recommended clinical examinations, screening for recognised risk factors for DDH has been implemented regionally.

Sensors with a higher sampling rate produce higher-quality data. However, for more extended periods of data acquisition, as in the continuous monitoring of patients, the handling of the generated big data becomes increasingly complicated. This study aimed to determine the validity and reliability of low-sampling-frequency accelerometer (SENS) measurements in patients with knee osteoarthritis. Data were collected simultaneously using SENS and a previously validated sensor (Xsens) during two repetitions of overground walking. The processed acceleration signals were compared with respect to different coordinate axes to determine the test–retest reliability and the agreement between the two systems in the time and frequency domains. In total, 44 participants were included. With respect to different axes, the interclass correlation coefficient for the repeatability of SENS measurements was [0.93–0.96]. The concordance correlation coefficients for the two systems’ agreement were [0.81–0.91] in the time domain and [0.43–0.99] in the frequency domain. The absolute biases estimated by the Bland–Altman method were [0.0005–0.008] in the time domain and [0–0.008] in the frequency domain. Low-sampling-frequency accelerometers can provide relatively valid data for measuring the gait accelerations in patients with knee osteoarthritis and can be used in the future for remote patient monitoring.

This study introduces temporary marriage (Siqa) and evaluates and investigates peoples' attitudes and tendencies toward it.Participants were 395 residents of Tehran. An attitude questionnaire was used to collect data. Descriptive results of the study showed that there was at least one case of temporary marriage in the families or relatives of the study population. Participants considered the following as the most important obstacles to temporary marriage in Iran: culture, family objections, logical objections, and permanent wife's objection. The comparison between the different groups showed that men, single people, employed people, and people with a history of temporary marriage in their family have a tendency toward temporary marriage. Although 25% of the study population was inclined to temporary marriage, its prevalence in society is about 9%. The main reason for its underdevelopment is the societal obstacles, expecially culture and family.

BackgroundAppropriate treatment of acromioclavicular joint dislocation is controversial. Acroplate fixation is one of the most common treatment methods of acromioclavicular joint (ACJ) dislocation. Based on the risk of re-dislocation after Acroplate fixation, we assumed that combined fixation with an Acroplate and a coracoclavicular screw helps improve the outcome.ObjectivesThe main purpose of the current study was to compare the outcome of ACJ dislocation treated with an Acroplate alone and in combination with coracoclavicular screw.Patients and MethodsThis study was carried out on 40 patients with ACJ dislocation types III to VI who were divided randomly into two equal groups: Acroplate group (P) and Acroplate in combination with coracoclavicular screw group (P + S). The screws were extracted 3-6 months postoperatively. The patients were followed for 1 year and Imatani’s score was calculated. Finally, the data were compared between the groups.ResultsThe mean Imatani’s score was significantly higher in P + S group (83.4 ± 14.1) than P group (81.2 ± 10.3) (P < 0.001). The mean duration of surgery was the same in the two groups (59.8 ± 9.4 minutes in group P V.s 64.3 ± 10.9 minutes in group P + S; P = 0.169). There were no cases of re-dislocation, degenerative changes and ossification and all patients returned to their previous jobs or sporting activities.ConclusionsUsing a coracoclavicular screw combined with an Acroplate can improve the patients’ function after ACJ disruption without any significant increase in surgical duration. Authors recommend this technique in the fixation of ACJ dislocation.
