Proximal junctional kyphosis and failure is a common complication of adult spinal deformity surgery, with osteoporosis as a risk factor. This retrospective study investigated the influence of long thoracolumbar fusion with pelvic fixation on regional bone density of adjacent vertebrae (Hounsfield units on computed tomography) and evaluated the association between bone loss and the incidence of proximal junctional kyphosis and failure. Patients who underwent long thoracolumbar fusion (pelvis to T10 or above) or single-level posterior lumbar interbody fusion (control group) between 2016 and 2022 were recruited. Routine computed tomography preoperatively and within 1-2 weeks postoperatively was performed. Postoperative changes in Hounsfield unit values in the vertebrae at one and two levels above the uppermost instrumented vertebrae (UIV + 1 and UIV + 2) were evaluated. Overall, 127 patients were recruited: 45 long fusion (age, 73.9 ± 5.6 years) and 82 proximal junctional kyphosis and failure (age, 72.5 ± 9.3 years). Postoperative computed tomography was performed at a median [interquartile range] of 3.0 [1.0-7.0] and 4.0 [1.0-7.0] days, respectively. In both groups, Hounsfield unit values at UIV + 2 were significantly decreased postoperatively. In the long-fusion group, Hounsfield unit values at UIV + 1 and UIV + 2 were significantly lower in patients with proximal junctional kyphosis and failure (within 18 months postoperatively) than in those without proximal junctional kyphosis and failure. Proximal junctional kyphosis and failure and long thoraco-pelvic fusion negatively affect regional Hounsfield unit values at adjacent levels immediately after surgery. Patients with subsequent proximal junctional kyphosis and failure show greater postoperative bone loss at adjacent levels than those without.

Lower Urinary Tract Symptoms Jul 2024To analyze the management strategies in the children who had treatment-resistant dysfunctional voiding (DV).
OBJECTIVES
To analyze the management strategies in the children who had treatment-resistant dysfunctional voiding (DV).
METHODS
Among 75 children with DV who underwent pelvic floor biofeedback therapy (BF) between 2013 and 2020, 16 patients (14 girls, 87.5%) with a mean age of 9.81 ± 2.53 years that showed incomplete clinical response following urotherapy and initial BF sessions were retrospectively reviewed. The demographic and clinical characteristics, DVSS, and uroflowmetry parameters were recorded before and after the initial BF sessions. Subsequent treatments after initial BF and clinical responses of patients were noted.
RESULTS
Clinical success was observed in one patient by addition of an anticholinergic and in three patients with combination of salvage BF sessions and anticholinergics, whom had predominant overactive bladder (OAB) symptoms. The success rate of TENS alone and in combination with other treatment modalities was 88.8% (8/9 patients). In addition, salvage BF sessions (range 2 to 3) enabled clinical success in five (50%) of 10 cases as a combination with anticholinergics or TENS. In case of incomplete emptying without OAB, adequate clinical response to Botulinum-A was observed during an average follow-up of 29 months in two boys who did not respond to alpha-blockers, even though one required repeat injection after 10 months. The total clinical success rate was 87.5% (14/16 patients) after a median follow-up of 24 months. VV-EBC and Qmax increased by a mean of 30.89% and 7.13 mL/min, respectively, whereas DVSS decreased by a mean of 8.88 points and PVR-EBC decreased by a median of 19.04%.
CONCLUSIONS
Our findings showed that clinical success in resistant DV was achieved by various combination treatments in the majority of children. However, a small group may still have persistent, bothersome symptoms despite multiple treatment modalities.

BACKGROUND
Compensatory vertical head and pelvis movement asymmetry may occur in trotting horses with a primary cause of lameness in one end of the body due to the weight shifting between limbs, leading to apparent combined forelimb and hindlimb lameness (CFHL). Little is known about CFHL patterns observed with body-mounted inertial sensors (BMIS) and regardless of their underlying mechanisms, compensatory and secondary lameness may complicate the definitive identification of the primary causes of lameness.
OBJECTIVE
Determine associations between vertical pelvic movement asymmetry and location of primary lameness in ipsilateral CFHL cases where hindlimb lameness is solely impact or push-off type.
STUDY DESIGN
Retrospective cohort.
METHODS
From a body-mounted inertial sensor (BMIS) evaluated equine lameness database, we identified cases with a consistent, low-variability ipsilateral impact (IpI) or ipsilateral pushoff (IpP) hindlimb lameness in a straight-line trot and that had definitive diagnoses. Cases were categorised by lameness location to the limb(s), diagnosis, and ratio of the amplitude of forelimb to hindlimb lameness (Fore/Hind). Differences in the numbers of IpI and IpP cases in these categories were analysed with chi-square tests, effect sizes, and odds ratios.
RESULTS
Among the 2375 total lameness cases screened, 49 IpI and 36 IpP cases met the criteria for consistency, low variability, and definitive diagnosis. IpI cases were more likely than IpP cases to have forelimb-only lameness causes when Fore/Hind >1 (OR = 43, 95% CI = 2.3-798). IpP cases were more likely than IpI cases to have hindlimb-only causes at both Fore/Hind >1.0 (OR = 20, 95% CI = 2.2-200) and <1.0 (OR = 14, 95% CI = 2.9-66.7). Compared with IpI, IpP cases were more frequently diagnosed with tendon, suspensory ligament, or high-motion joint disorders in hindlimbs (OR = 3.6, 95% CI = 1.1-12.3) and less with unknown causes (OR = 13.2, 95% CI = 3.2-75.2). In IpI cases, positive forelimb regional anaesthesia often reduced hindlimb lameness, whereas in IpP cases, positive hindlimb regional anaesthesia typically lessened forelimb lameness.
MAIN LIMITATIONS
Most cases were Quarter Horses. The likelihood of location and cause of lameness may be different for other breeds.
CONCLUSIONS
The type of pelvic movement asymmetry observed in IpI and IpP cases is linked to the location and underlying cause of the primary lameness.

Wolffian tumor and its nosologic relative, the recently defined STK11 adnexal tumor are rare neoplasms thought to arise from mesonephric remnants. These tumors typically arise in the broad ligament, fallopian tube, and ovarian hilum and although most are associated with a good prognosis, up to 50% of STK11 adnexal tumors demonstrate aggressive clinical behavior. The chief differential diagnoses include endometrioid adenocarcinoma and sex cord stromal tumors. However, the morphologic and immunohistochemical features of these tumors exhibit considerable overlap with peritoneal mesothelioma. To fully characterize their immunophenotypic signature, we examined a total of 21 cases (18 Wolffian and 3 STK11 adnexal tumors) with standard markers used in the diagnosis of mesothelioma. Morphologic and immunohistochemical (IHC) features were reviewed and additional IHC performed for cases with available material. Patient age ranged from 25 to 73 (mean: 51) years. Sites included adnexa/broad ligament (6, 28%), paratubal (5, 24%), ovary/paraovarian (5, 24%), tubal (intraluminal) (2, 9.5%), pelvis (2, 9.5%), and liver (1, 5%). The mean tumor size was 9.3 cm (range: 0.2 to 22 cm). The histomorphology in most cases (14/21, 66%) consisted of tubular to solid sheets of neoplastic cells lined by columnar to cuboidal cells containing uniform round to oval nuclei. Compressed tubules with slit-like lumens and sieve-like pattern were also seen in at least 7 (33%) cases. Three cases demonstrated interanastomosing cords and trabeculae of epithelioid cells with cribriform and microacinar patterns growing within prominent myxoid stroma as described in STK11 adnexal tumors. In the cases with available IHC for 3 mesothelial markers (calretinin, WT1, D2-40), 55.5% (5 of 9) showed reactivity with all 3 markers. In cases with at least 2 available mesothelial markers, 69% (11/16) were positive for 2 markers (mostly calretinin and WT1). Claudin-4, MOC31, and BER-EP4 were negative in most cases tested (78% [7/9], 71.4% [5/7], and 100% [6/6], respectively). Given the resemblance to mesothelioma, there was initial strong consideration and/or actual misdiagnosis of mesothelioma in 3 cases (14%). In summary, the morphologic and immunohistochemical features of Wolffian tumor and its recently defined relative, STK11 adnexal tumor, can lead to misdiagnosis of mesothelioma, particularly when encountered in the disseminated or metastatic setting. Wolffian tumor and STK11 adnexal tumor should be considered in the differential diagnosis of all pelvic and peritoneal mesotheliomas.

Ramirez, VJ, Bazrgari, B, Spencer, A, Gao, F, and Samaan, MA. Influence of repetitions-to-failure deadlift on lumbo-pelvic coordination, with and without body armor. J Strength Cond Res XX(X): 000-000, 2024-Repetition-to-failure (RTF) deadlift is a training modality for building lifting capacity that is often implemented by service members to maintain a minimum level of physical fitness. Despite its physiological benefits, little is known about the effects of RTF on the biomechanics of lumbar spine. Additionally, the effects of heavy deadlift training with body armor are unknown. The aim of this study was to investigate the effects of RTF deadlift on lumbo-pelvic coordination and posture, with and without body armor. Twenty-three healthy subjects, recreational powerlifters, were recruited for this study. Kinematics of the trunk and pelvis were measured using a 3D motion capture system while subjects conducted RTF deadlifts with a 68-kg low-handle hexagonal bar with and without a simulated body armor (22.68 kg). Lumbo-pelvic coordination was characterized using a vector coding approach and coupling angle variability (CAV) using circular statistics, over 3 equally divided segments of the lifting phase. More specifically, the coupling angle values were used to determine the coordination pattern between the thorax and pelvis. Trunk and pelvis ranges of motion and the amount of in-phase lumbo-pelvic coordination pattern increased with RTF deadlift. Additionally, CAV of the first and the third segments of deadlift cycle increased with RTF deadlift. Increase in variability of lumbo-pelvic coordination and peak trunk flexion (i.e., indication of increased mechanical demand of lifting on the spine), as a result of RTF deadlifting, can have deleterious soft tissue responses and contribute to an increase in risk of lower back injury.

A 30-year-old female patient with a history of infertility and no pregnancy presented to the gynecologic endometriosis clinic for follow-up 1 month after oocyte retrieval, to be evaluated for pelvic optimization before potential embryo transfer, with worsening dysmenorrhea, dyspareunia, and overall pelvic pain. Eleven years prior, the patient had undergone left ovarian cystectomy for treatment of endometrioma, as well as excision of deep infiltrative endometriosis. The oocyte retrieval procedure, where more than 30 eggs were retrieved, was complicated by ovarian hyperstimulation syndrome and intraperitoneal bleeding, which necessitated admission to the intensive care unit (ICU) for 3 days. Following discharge from the ICU, the patient experienced occasional on-and-off pressure of the urinary bladder and persistent aching pelvic pain. At the 1-month follow-up appointment, the patient's vital signs were assessed (blood pressure, 142/94 mm Hg; pulse rate, 95 per minute; temperature, 96.8 °F [36 °C]). Routine blood investigations, including white blood cell count, were within normal limits. Physical examination showed the abdomen was soft but there was mild pelvic tenderness. The serum β-human chorionic gonadotropin test result was negative for pregnancy, and urinalysis testing showed no leukocyte esterase or nitrites. MRI of the pelvis (Figs 1-3) was performed to evaluate the worsening pain.

Psammoma bodies in cervicovaginal cytology are a rare finding associated with malignant tumours. A 62-year-old woman was referred to our centre for cytology with nuclear atypia and psammomatous bodies suspicious of malignancy. A complete gynaecological examination was performed including colposcopy and ultrasound without significant changes. Hysteroscopy was performed to detect endometrial or endocervical malignancy, endometrial biopsy showed psammoma bodies and atrophic endometrium. Endocervical and cervical biopsies were negative for malignancy. Cervicovaginal cytology and human papillomavirus (HPV) testing were repeated. The result was suggestive of adenocarcinoma and negative for HPV. Laparoscopic hysterectomy with bilateral salpingo-oophorectomy was indicated due to two cervicovaginal cytologies with suspicion of malignancy. Low-grade peritoneal serous carcinoma was diagnosed on the surface of the uterus, ovaries and peritoneum. A second laparoscopy was performed to exclude other pelvic or abdominal lesions, and disease was found in the peritoneum of the pelvis, abdomen and omentum. Adjuvant treatment with six cycles of carboplatin and paclitaxel was indicated. Psammoma bodies in cervicovaginal cytology are a rare clinical situation, and it is mandatory to exclude malignancy.

OBJECTIVES
The aim of this cross-sectional study was to update the results of the first Swiss Job Analysis Survey in 2009 with regard to the demographics of the chiropractors and their patients, practice characteristics, interprofessional collaboration, the importance of imaging, and job satisfaction.
METHODS
In April 2020, the adapted 2009 questionnaire was electronically sent to all members of the Swiss Chiropractic Association ChiroSuisse (N = 316). Only complete questionnaires were included in the descriptive analysis. Demographic data were compared to all ChiroSuisse members.
RESULTS
The response rate was 76.3%. The mean age of the participants was 49.9 ± 12.3 years and 62.2% were male. Among the younger chiropractors (≤ 15 years of professional experience), 51.6% were male. Almost half of the participants worked in a joint office and one in five worked in a multidisciplinary setting. The typical chiropractic patient was middle-aged, female and suffered most frequently from acute lower back/pelvis pain and second most frequently from neck pain. Diversified osseous adjustment was the most commonly used technique, followed by advice on activities of daily living and trigger point therapy. Images (X-ray, CT, MRI) were ordered in less than 20% of the patients. 95% of the chiropractors were satisfied with their career choice.
CONCLUSIONS
No changes to 2009 were observed in terms of the typical patient or the applied techniques. However, the Swiss chiropractors were more experienced, to a larger proportion female, more often worked in multidisciplinary settings, and ordered fewer images. Job satisfaction among Swiss chiropractors was high.

Malakoplakia is a rare granulomatous, chronic inflammatory disease generally affecting the urogenital organs, though it can arise in other organs. The clinical manifestations of malakoplakia vary depending on the affected organ. The final diagnosis is confirmed by the presence of Michaelis-Gutmann bodies on pathology. This report describes a case of pelvic malakoplakia accompanied by an ovarian tumour-cutaneous fistula, initially misdiagnosed as advanced ovarian cancer invading the anterior abdominal wall with left pleural effusion based on imaging studies and increased serum carbohydrate antigen 19-9. The patient underwent left thoracentesis and fluid collection from the fistula tract for cytology, which showed no malignancy. She underwent primary debulking surgery, including removal of the fistula tract from anterior abdominal wall. Histopathological examination revealed malakoplakia coexisting with mucinous cystadenoma of the left ovary. For postoperative management, she received prolonged oral antibiotics for 6 months. There was no evidence of disease recurrence at the 24-month follow-up.
