Normal Values of Ipsilateral and Contralateral Auditory Brainstem Responses Induced by Click in Normal Hearing Youth of Different Gender / 听力学及言语疾病杂志

Objective To study the characteristics of ipsilateral and contralateral ABRs in young adults with normal hearing,and the differences between the genders and recording sides(ipsilateral vs.contralateral).Methods Eighty-eight subjects(176 ears)aged 18 to 21 years old were recruited to perform ipsilateral and contralateral ABRs evoked by 70 dB nHL click.The mean and standard deviation of the latency of waves Ⅰ,Ⅲ,Ⅴ and the in-terpeak interval of Ⅰ-Ⅲ,Ⅲ-Ⅴ and Ⅰ-Ⅴ of ipsilateral,and waves Ⅲ,Ⅴ and the interpeak interval ABRs of Ⅲ-Ⅴof contralateral ABRs were calculated.The ANOVA was used to study the differences between the males and fe-males,and between ipsilateral and contralateral recordings.Results Males showed delayed peak and interpeak la-tency in waves Ⅲ,Ⅴ,Ⅰ-Ⅲ,Ⅲ-Ⅴ,Ⅰ-Ⅴ(F=13.13～60.82,P＜0.001).The peak and interpeak latency of waves Ⅲ,Ⅴ,Ⅲ-Ⅴ(F=22.43～76.18,P＜0.001)showed difference between ipsilateral and contralateral ABRs.The latency of ipsilateral ABRs in waves Ⅲ were delayed,but in other components were earlier.Conclusion This study established the normal values of ipsilateral and contralateral ABRs in young adults with normal hearing,and reported the gender and recording sides(ipsilateral vs.contralateral)differences in ABRs.

Surgical treatment for ipsilateral femoral neck and shaft fracture / 中国骨伤

OBJECTIVE@#To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications.@*METHODS@#From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus.@*RESULTS@#All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair.@*CONCLUSION@#Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.

More microinvasive foci in larger tumours of breast ductal carcinoma in situ

INTRODUCTION@#Microinvasion (Mi) is often thought to be an interim stage between ductal carcinoma in situ (DCIS) and invasive ductal carcinoma. This study aimed to investigate the potential influence of Mi on survival and assess its correlations with clinicopathological parameters, prognosis and molecular markers.@*METHODS@#The number of Mi foci in a cohort of 66 DCIS-Mi cases was assessed from haematoxylin and eosin-stained sections. Disease-free survival, clinicopathological parameters and biomarker expression were correlated with the number of Mi foci.@*RESULTS@#Higher numbers of Mi foci were found in larger tumours (P = 0.031).@*CONCLUSION@#Greater extent of DCIS is associated with multifocal Mi.

Comparison of prophylactic ipsilateral and bilateral central lymph node dissection in papillary thyroid carcinoma: a meta-analysis

Abstract Objective: The scope of surgical resection for paratracheal (level VI) lymph nodes in patients with Papillary Thyroid Carcinoma (PTC) remains debatable. The aim of our study was to evaluate the effectiveness and safety of prophylactic ipsilateral Central Neck lymph node Dissection (CND) versus bilateral CND at the time of total thyroidectomy for Clinically Node-negative (cN0) unilateral PTC. Methods: A systematic retrieval of electronic databases, including Pubmed, Web of Science, and the China Journal Net, was conducted from January 1990 to September 2021. Outcome data of interest included transient hypoparathyroidism, permanent hypoparathyroidism, transient Recurrent Laryngeal Nerve (RLN) injury, permanent RLN injury and local recurrence. We constructed the summary Odds Ratios (ORs) and 95% Confidence Intervals (CIs) for every study with either fixed or random effect models. Results: A full total of 1792 patients from 6 studies were enrolled. Our meta-analysis showed that transient hypoparathyroidism was significantly more frequent in bilateral CND group (OR = 0.58; 95% CI 0.44-0.76). The prevalence of permanent hypoparathyroidism was significantly higher in bilateral CND group patients compared to those in ipsilateral CND group (OR = 0.26; 95% CI 0.15-0.45). On the other hand, our meta-analysis indicated that there were no significant differences in the incidence of transient RLN injury, permanent RLN injury and local recurrence. Conclusions: Compared with bilateral CND, the rate of temporary and permanent hypoparathyroidism in ipsilateral CND is lower, but the local recurrence is similar. It may be presumptuous to suggest that ipsilateral CND is an adequate treatment for cN0 unilateral PTC.

Dysmenorrhea due to undiagnosed obstructed hemi-vagina and ipsilateral renal anomaly syndrome can become a cause of suicide

BACKGROUND@#A Japanese woman in her early twenties had committed suicide, jumped from a 25-meter high bridge into a lake. She had been suffering from severe dysmenorrhea and general fatigue monthly.@*RESULTS@#A forensic autopsy revealed indications of a bicorporeal uterus, obstructed hemi-vagina, and ipsilateral renal agenesis, which lead to a diagnosis of obstructed hemi-vagina and ipsilateral renal anomaly (OHVIRA) syndrome. On the right side of the uterus, an enclosed cavity composed of black clots was observed. Histological findings suggested that her endometrium was in the early proliferative phase, implying that she was in the menstrual phase just before her death. She may have been suffering from severe lower abdominal pain from the increased pressure of the closed uterus cavity.@*CONCLUSIONS@#This case indicates that dysmenorrhea from undiagnosed OHVIRA syndrome can possibly lead to a suicide attempt. In Japan, because suicide was the leading cause of death for people aged 15 to 39 in 2019, preventive measures for suicide should be promoted. The present case also suggests that intervention for dysmenorrhea may prevent this in adolescent woman.

Construction of a nomogram prediction model for pathological complete response (pCR) of ipsilateral supraclavicular lymph node after neoadjuvant chemotherapy for breast cancer with first diagnosis of ipsilateral supraclavicular lymph node metastasis / 中华肿瘤杂志

Objective: To develop a predictive model for pathologic complete response (pCR) of ipsilateral supraclavicular lymph nodes (ISLN) after neoadjuvant chemotherapy for breast cancer and guide the local treatment. Methods: Two hundred and eleven consecutive breast cancer patients with first diagnosis of ipsilateral supraclavicular lymph node metastasis who underwent ipsilateral supraclavicular lymph node dissection and treated in the Breast Department of Henan Cancer Hospital from September 2012 to May 2019 were included. One hundred and forty two cases were divided into the training set while other 69 cases into the validation set. The factors affecting ipsilateral supraclavicular lymph node pCR (ispCR)of breast cancer after neoadjuvant chemotherapy were analyzed by univariate and multivariate logistic regression analyses, and a nomogram prediction model of ispCR was established. Internal and external validation evaluation of the nomogram prediction model were conducted by receiver operating characteristic (ROC) curve analysis and plotting calibration curves. Results: Univariate logistic regression analysis showed that Ki-67 index, number of axillary lymph node metastases, breast pCR, axillary pCR, and ISLN size after neoadjuvant chemotherapy were associated with ispCR of breast cancerafter neoadjuvant chemotherapy (P<0.05). Multivariate logistic regression analysis showed that the number of axillary lymph node metastases (OR=5.035, 95%CI: 1.722-14.721, P=0.003), breast pCR (OR=4.662, 95%CI: 1.456-14.922, P=0.010) and ISLN size after neoadjuvant chemotherapy (OR=4.231, 95%CI: 1.194-14.985, P=0.025) were independent predictors of ispCR of breast cancer after neoadjuvant chemotherapy. A nomogram prediction model of ispCR of breast cancer after neoadjuvant chemotherapy was constructed using five factors: number of axillary lymph node metastases, Ki-67 index, breast pCR, axillary pCR and size of ISLN after neoadjuvant chemotherapy. The areas under the ROC curve for the nomogram prediction model in the training and validation sets were 0.855 and 0.838, respectively, and the difference was not statistically significant (P=0.755). The 3-year disease-free survival rates of patients in the ispCR and non-ispCR groups after neoadjuvant chemotherapy were 64.3% and 54.8%, respectively, with statistically significant differences (P=0.024), the 3-year overall survival rates were 83.8% and 70.2%, respectively, without statistically significant difference (P=0.087). Conclusions: Disease free survival is significantly improved in breast cancer patients with ispCR after neoadjuvant chemotherapy. The constructed nomogram prediction model of ispCR of breast cancer patients after neoadjuvant chemotherapy is well fitted. Application of this prediction model can assist the development of local management strategies for the ipsilateral supraclavicular region after neoadjuvant chemotherapy and predict the long-term prognosis of breast cancer patients.

Correlation of clinicopathology and ipsilateral axillary lymph node metastasis with Ki-67 expression in non-special invasive breast cancer / 西安交通大学学报(医学版)

【Objective】 To investigate the clinicopathological characteristics of non-specific invasive breast cancer (IBC-NST) and the relationship between ipsilateral axillary lymph node metastasis and Ki-67 expression. 【Methods】 A total of 101 patients with IBC-NST were retrospectivily recruited and divided into two groups with high expression of Ki-67 (70cases) and low expression of Ki-67 (31cases). The χ2 test and Kruskal-Wallis H test were used to compare the clinical and pathological characteristics and other count data of patients between the groups. The comparison of ultrasound diagnosis of ipsilateral axillary lymph node metastasis and pathological results was calculated using correlation values such as sensitivity and specificity. The correlation between ipsilateral axillary lymph node metastasis and Ki-67 expression was analyzed with Spearman correlation analysis. 【Results】 In different Ki-67 expression groups, the size of tumor mass, histological grade of breast cancer, and clinical stage were statistically different between Ki-67 expression groups (P<0.05). The positive expression rate of tumor mass ≥2 cm (58.57%), histological grade Ⅲ (32.86%), clinical stages Ⅲ (34.29%) and Ⅳ (5.71%) was higher in the Ki-67 high expression group; ipsilateral axillary lymph node metastasis and Ki-67 high expression were positively correlated (r=0.393, P<0.05). 【Conclusion】 In IBC-NST cases, the tumor mass ≥ 2 cm, histological grade Ⅲ, clinical stage Ⅲ, and Ⅳ are correlated with the high expression of Ki-67. At the same time, ipsilateral axillary lymph node metastasis and Ki-67 high expression are positively correlated, which provides reference for IBC-NST proliferation assessment and clinical intervention.

Obstructed hemivagina with ipsilateral renal anomaly with ureteric remnant in a prepubertal female / Philippine Journal of Obstetrics and Gynecology

@#Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), or Herlyn–Werner–Wunderlich syndrome, is a rare Müllerian duct anomaly that is characterized by a triad of uterus didelphys, unilateral obstructed vagina, and ipsilateral renal agenesis. Patients with this anomaly usually present after menarche with abdominal pain or a pelvic mass which worsens over some time. Herein, presented is a case of a 12‑year‑old nulligravid with cyclic pelvic pain and palpable pelvic mass after her menarche. A series of diagnostic tests were done which were compatible with the diagnosis of OHVIRA with an associated finding of ectopic ureteral insertion into the obstructed hemivagina and nonfunctional urinary bladder. The patient underwent diagnostic hysteroscopy, cystoscopy, and full resection of the longitudinal vaginal septum as well as drainage of hematocolpos, which are the main treatment of the patient with OHVIRA.

Ipsilateral hemichorea after striatal hemorrhage

@#Hemichorea after a striatal lesion of the ipsilateral side of the cerebral hemisphere is a very rare condition. A 72-year-old female presented with right-sided bradykinesia and left-sided hemichorea after a left striatal hemorrhage. In a shape analysis of the brain conducted via MRI, her damaged left basal ganglia was severely contracted whereas her right dorsolateral putamen surface was deformed and hypertrophied. Excessive compensation of the contralateral hemisphere may be a possible mechanism of ipsilateral hemichorea in this case.

Post-thoracotomy ipsilateral shoulder pain: What should be preferred to optimize it - phrenic nerve infiltration or paracetamol infusion?

Background: Post thoracotomy ipsilateral shoulder pain (PTISP) is a distressing and highly prevalent problem after thoracic surgery and has not received much attention despite the incidence as high as 85%. Objectives: To study the effect of phrenic nerve infiltration with Ropivacaine compared to paracetamol infusion on PTISP in thoracotomy patients with epidural analgesia as standard mode of incisional analgesia in both the groups. Study Design: Prospective Randomised and Double Blind Study. Methods: 126 adult patients were divided randomly into 2 groups, “Group A (Phrenic Nerve Infiltration Group) received 10 mL of 0.2% Ropivacaine close to the diaphragm into the periphrenic fat pad” and “Group B (Paracetamol Infusion Group) received 20mg/kg paracetamol infusion” 30 minutes prior to chest closure respectively. A blinded observer assessed the patients PTISP using the VAS score at 1, 4, 8, 12 and 24 hours (h) postoperatively. The time and number of any rescue analgesic medication were recorded. Results: PTISP was relieved significantly in Group A (25.4℅) as compared to Group B (61.9℅), with significantly higher mean duration of analgesia in Group A. The mean time for first rescue analgesia was significantly higher in Group A (11.1 ± 7.47 hours) than in Group B (7.40 ± 5.30 hours). The number of rescue analgesic required was less in Group A 1.6 ± 1.16 as compared to Group B 2.9 ± 1.37 (P value <0.5). Conclusions: Phrenic Nerve Infiltration significantly reduced the incidence and delayed the onset of PTISP as compared to paracetamol infusion and was not associated with any adverse effects.

Motor Skill Learning on the Ipsi-Lateral Upper Extremity to the Damaged Hemisphere in Stroke Patients

PURPOSE: This study examined whether there is a difference in motor learning through short-term repetitive movement practice in stroke survivors with a unilateral brain injury compared to normal elderly participants. METHODS: Twenty-six subjects who were divided into a stroke group (n=13) or sex-aged matched normal elder group (n=13) participated in this study. To evaluate the effects of motor learning, the participants conducted a tracking task for visuomotor coordination. The accuracy index was calculated for each trial. Both groups received repetitive tracking task training of metacarpophalangeal joint for 50 trials. The stroke group performed a tracking task in the upper extremity insi-lesional to the damaged hemisphere, and the normal elder group performed the upper extremity matched for the same side. RESULTS: Two-way repetitive ANOVA revealed a significant difference in the interactions (time×group) and time effects. These results indicated that the motor skill improved in both the stroke and normal elder group with a tracking task. On the other hand, the stroke group showed lesser motor learning skill than the normal elder group, in comparison with the amount of motor learning improvement. CONCLUSION: These results provide novel evidence that stroke survivors with unilateral brain damage might have difficulty in performing ipsilateral movement as well as in motor learning with the ipsilateral upper limb, compared to normal elderly participants.

Major Limb Replantation of Lower Leg Amputation with Ipsilateral Distal Femoral Comminuted Fracture in Old Age: A Case Report

The development of microsurgical techniques has also increased the success rate of replantation surgery. This paper reports the results of limb replantation performed on a lower extremity amputation that was associated with crush amputation and an ipsilateral comminuted fracture in and elderly patient. A 68-year-old female presented with a right distal tibia amputation due to a traffic accident. At that time, with a comminuted fracture in the distal femoral condyle, simple wound repair was recommended, but the caregivers strongly wanted replantation. Three years after surgery, normal walking was possible without a cane and the patient was satisfied with the function and aesthetics. What used to be contraindicated in limb replantation in the past are now indications due to the development of microsurgical techniques, surgical experience, and postoperative rehabilitation treatment. If the patient is willing to be treated, good results in contraindications can be obtained.

Characteristics and Surgical Outcomes of Intertrochanteric or Subtrochanteric Fractures Associated with Ipsilateral Femoral Shaft Fractures Treated with Closed Intramedullary Nailing: A Review of 31 Consecutive Cases over Four Years at a Single Institution / 대한고관절학회지

PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.

Ipsilateral proximal and distal radius fractures with unstable elbow joint: Which should we address first? / 中华创伤杂志(英文版)

Simultaneous ipsilateral fractures involving radial head and distal end of radius are uncommon. We present our thoughts on which fracture should be addressed first. A 68-year-old lady sustained an ipsilateral fracture of the right radial head and distal end of radius following a fall. Clinically her right elbow was posteriorly dislocated and right wrist was deformed. Plain radiographs showed an intraarticular fracture of the distal end of radius and a comminution radial head fracture with a proximally migrated radius. Magnetic resonance imaging (MRI) showed no significant ligament injuries. We addressed her distal radius first with an anatomical locking plate followed by her radial head with a radial head replacement. Our rationale to treat the distal end radius: first was to obtain a correct alignment of Lister's tubercle and correct the distal radius height. Lister's tubercle was used to guide for the correct rotation of the radial head prosthesis. Correcting the distal end fracture radial height helped us with length selection of the radial head prosthesis and address the proximally migrated radial shaft and neck. Postoperative radiographs showed an acceptable reduction. The Cooney score was 75 at 3 months postoperatively, which was equivalent to a fair functional outcome.

The value of the signal intensity ratio of the extraocular muscle and the ipsilateral white matter of the MRI in the evaluation of the activity of thyroid-associated ophthalmopathy / 中华内分泌代谢杂志

Objective To investigate the quantitative value of the signal intensity ratio of extraocular muscle and ipsilateral white matter measured by MRI for the evaluation of activity in thyroid-associated ophthalmopathy. Methods A total of 129 patients and 245 eyeballs with thyroid-associated ophthalmopathy were enrolled in this study and this 245 eyeballs were set as thyroid-associated ophthalmopathy group(TAO group). There were 10 patients with newly diagnosed Graves'disease and in the same period and these 20 eyeballs were set as graves'disease group(GD group). 32 normal people from annual physical test excluded thyroid and eye diseases and their 64 eyes were selected randomly for the normal control group(NC group). The signal intensity of the extraocular muscle and the ipsilateral white matter on the MRI images were measured, while did exophthalmos and the width of the inner fat of eyeballs (FWs)measurements in the same time. Results SIR,FWs,and exophthalmos of TAO group were higher than those of the other 2 groups[SIRs:1.71(1.40,2.10)vs 1.26(1.22,1.34)and 1.23(1.14,1.32);FWs:8.04(6.70, 8.71)mm vs 6.16(4.86,7.08)mm and 6.93(6.41,7.65)mm,exophthalmos:20.10(18.56,22.15)mm vs 15.40(14.87,16.60)mm and 14.73(13.40,16.07)mm,all P<0.05]. The reference value of SIR establishing based on SIRs of NC group is less than 1.37. In total 129 TAO patients,55 patients(with 106 eyeballs)have a clinical activity score(CAS). Then,these eyeballs were grouped to activity and non-activity(grouped by CAS≥3),and the baseline group difference of these 2 groups was not statistically significant. The SIRs and exophthalmos of activity group were higher than the non-activity group[SIRs:1.70(1.45,2.33)vs 1.41(1.25,1.75); exophthalmos:(20.38 ± 2.40)mm vs(19.05 ± 3.70)mm,all P<0.05]. But the difference of FWs of these two groups was not statistically significant(P>0.05). The SIRs and CAS had a positive correlation(r=0.580,P=0.000),through the receiver operating characteristic curve(ROC)we get the best diagnostic performance of TAO activity when the SIR≥1.56(sensibility=65.6%,specificity=89.1%,AUC=0.815,P=0.000). Conclusion The signal intensity ratio of extraocular muscle and ipsilateral white matter may discriminate the activity of TAO early as a quantitative indicator, reflecting its efficacy,and is worth clinically generalizing.

Relationship between Ipsilateral Motor Deficits on the Less-Affected Side and Motor Function Stage on the Affected Side

PURPOSE: Aim of this study was to investigate whether there are ipsilateral motor deficits for visuospatial accuracy and fine movements by making a comparison between stroke patients and healthy subjects. We examined whether ipsilateral motor deficits are influenced by the level of functional movements and muscle strength of the upper and lower extremities of the affected side. METHODS: Thirty post-stroke subjects and 20 normal aged matched subjects were recruited. Outcome measures for less-affected side were the tracking task and nine-hole pegboard test. Fugl-Meyer test and motricity index were applied for the measurement of functional movements and muscle strength of affected side. RESULTS: Tracking task and nine-hole pegboard test was significantly different between control and experimental group. In terms of accuracy index according to tracking, the experimental group showed a lower accuracy index in the MCP joint than the control group. However, there were no significant difference relation between the level of motor function of the affected side and the motor deficit level of ipsilateral side. CONCLUSION: Ipsilateral motor deficits may have significant clinical implications. It needs to be noted that although many patients, families, and medical staff are focused only on motor deficits of the affected side, motor deficits of the sound side can cause difficulties in daily living movements requiring delicate movements. In addition, there was no significant correlation between the level of motor function of the affected side and motor deficits of the sound side.
