Morphometric and Histological Study of Breast Lesions with Special Reference to Proliferative Activity and Invasiveness

Breast carcinoma is the most common cause of carcinoma death in women. Sometimes, difficulty arises to differentiate between premalignant lesions and carcinoma by routine histopathology. Our study was done to establish the role of morphometry and immunohistochemistry to solve this problem. In this study, total 60 cases of different breast lesions were included and 10 controls were also included to compare the results with the normal findings. They were studied by hematoxylin and eosin-stained sections for morphometry and routine histological study; as well as by proliferative markers such as proliferating cell nuclear antigen and p53. Invasiveness was studied using immunohistochemical staining with 34 βE12 monoclonal antibody. Statistically significant differences were found in morphometric parameters and in expression of proliferative markers between most of them. Morphometry and immunohistochemistry help in the proper diagnosis of different breast lesions that lie in the gray zone on routine histopathology.     

Simple preoperative parameters to assess technical difficulty during a radical perineal prostatectomy

Purpose

We aimed to propose a practical selection method predicting the easier radical perineal prostatectomy (RPP) cases before the operation.

Methods

Fifty sequential RPP cases were divided into two groups according to the estimated difficulty of the operation (Group I: Easier, Group II: Difficult) which was assessed by using a RPP difficulty scale, constituted by three parameters (operation time, blood loss, and the judgment of the surgeon) each ranging between 1 and 3 points. As the localization parameters, skin-to-prostatic apex (SPAD) and skin-to-prostatic base (SPBD) distances and distance between bilateral ischial tuberosities (ITD) were measured. During suprapubic ultrasonography, a probe-divergence angle (PDA) and prostate volumes (PV) were recorded. These parameters were compared between the groups.

Results

In Group I (n = 29) and Group II (n = 21), the difficulty scores were 4.37 (3–5) and 6.80 (6–9), respectively. Data of age, clinical stages, and findings of digital rectal examination were not different between groups. While SPBD, SPAD, and ITD values were found similar (p > 0.05), PDA and PV were significantly different. PDA was > 45 degree in 21 cases in Group I (72.4 %) and in 7 cases in Group II (33.3 %) (p = 0.011). The mean of PV was 37.4 (20–60) cc and 49.9 (30–75) cc in Group I and Group II, respectively (p = 0.001).

Conclusions

While planning RPP operations, by selecting the prostate cancer cases with a prostate of low volume and localized deeper in the pelvis during suprapubic ultrasonography, urologists may have a chance to perform this technique more easily during the learning period.     

Cholinergic control of morphine‐induced locomotion in rostromedial tegmental nucleus versus ventral tegmental area sites

M5 muscarinic acetylcholine receptors expressed on ventral tegmental dopamine (DA) neurons are needed for opioid activation of DA outputs. Here, the M5 receptor gene was bilaterally transfected into neurons in the ventral tegmental area (VTA) or the adjacent rostromedial tegmental nucleus (RMTg) in mice by means of a Herpes simplex viral vector (HSV) to increase the effect of endogenous acetylcholine. Three days after HSV‐M5 gene infusion in VTA sites, morphine‐induced locomotion more than doubled at two doses, while saline‐induced locomotion was unaffected. When the HSV‐M5 gene was infused into the adjacent RMTg, morphine‐induced locomotion was strongly inhibited. The sharp boundary between these opposing effects was found where tyrosine hydroxylase (TH) and cholinesterase labelling decreases (?4.00 mm posterior to bregma). The same HSV‐M5 gene transfections in M5 knockout mice induced even stronger inhibitory behavioural effects in RMTg but more variability in VTA sites due to stereotypy. The VTA sites where HSV‐M5 increased morphine‐induced locomotion receive direct inputs from many RMTg GAD‐positive neurons, and from pontine ChAT‐positive neurons, as shown by cholera‐toxin B retrograde tracing. Therefore, morphine‐induced locomotion was decreased by M5 receptor gene expression in RMTg GABA neurons that directly inhibit VTA DA neurons. Conversely, enhancing M5 receptor gene expression on VTA DA neurons increased morphine‐induced locomotion via cholinergic inputs.     

Computer-assisted analysis contour lines of aesthetic unit for the assessment of lip augmentation

Background

Lip augmentation and changing contour lines have become more popular ways of improving the appearance. However, validated measures of lip fullness for quantification of outcomes are needed; ethnic background and personal goals can optimise outcomes while tailoring lip enhancement treatment to each individual’s anatomy. The aim of this study is to analyse the morphological features of the lip in detail and to clarify the objective parameters in related with the subjective ones regarding the lip augmentation and lip reconstruction.

Methods

Standard photographs of the lips of 200 young Anatolian adults were calculated with linear and angular components. The features of the lower third of the face were analysed with the software program. Linear analyses (heights of the upper lip, the upper vermilion, the lower lip height, the lower vermillion and the chin height) and angular analyses (the upper lip, the lower lip, the apex and Cupid’s bow angles) were measured as reference points. The lip shape was classified into five groups: thin, very thin, medium, full and very full.

Results

The lower third of the face was divided into three segments (Sn–Sto, Sm–Me and Sto–Sm), and the largest portion of the lower face was occupied by the chin and the smallest by the lower lip height in both genders. The upper vermilion height was 8.07?±?1.8 mm in males and 7.08?±?1.5 mm in females. The lower vermilion height was 10.1?±?2.4 mm in males and 9.7?±?1.9 mm in females. The upper lip angle was calculated as 30.3?±?9.6° in males and 24.2?±?6.2°mm in females. The lower lip angle was calculated as 38.3?±?9.7° in males and 36.5?±?6.4° in females. Meanwhile, the angular measurements of Cupid’s bow (i.e., the apex and the central angle of Cupid’s bow) were smaller in men than in women. When the lip was analyzed, the medium and full types in upper and lower lips accounted for substantial fractions in men, whereas medium and thin types were predominant also in women.

Conclusions

With the help of certain software, this research has made possible to define the best cosmetical redesign solution of lip construction and augmentation with a natural appearance for the patient.Level of Evidence: Level III, diagnostic study.

     

Safety and efficacy of single-incision sling for female stress urinary incontinence: 3 years’ results

Introduction and hypothesis

The purpose of this study was to investigate the success and complication rates of single-incision sling for treating stress urinary incontinence (SUI), with a 3-year follow-up.

Methods

This study comprised 173 female patients with SUI or mixed urinary incontinence (MUI) with dominant SUI who underwent minisling procedure. All patients had positive cough stress test preoperatively; they were followed up for 3 years after surgery (1, 3, 6, 12 months, and yearly).

Results

Total follow-up was 36 months, and mean age 51 years (44–77); 128 (74 %) patients presented SUI and 45 (26 %) MUI. Objective and subjective cure and failure rates were 83.8 % (145 cases), 6.4 % (11 cases), and 9.8 % (17 cases), respectively. There were no differences in cure rates between 1 and 3 years. Mean body mass index was 28.7 (26.1–35.2), and mean operating time 7.9 min. (6.5–11.9). There were no major intraoperative complications. Eleven patients (6.4 %) had de novo urge incontinence that resolved using anticholinergic drugs; no patient had urinary retention. Vaginal mesh extrusion was reported in nine (5.2 %) patients.

Conclusions

The minisling system attained high success rates at 3 years’ follow-up. The procedure was easy to learn and has lower complication rate.

     

Evaluation of obstructive sleep apnea symptoms in pregnant women with chronic disease

Objective: Obstructive sleep apnea syndrome (OSAS) is a disease which is estimated to be undiagnosed to a large extent. Hence, the prevalence of OSAS in pregnant women is unknown. We aimed to evaluate the symptoms of obstructive sleep apnea in pregnant women with chronic diseases.

Methods: In the study, 97 pregnant women with chronic diseases and 160 healthy pregnant women were included. A form questioning socio-demographic characteristics and pregnancy characteristics, Epworth scale and the Berlin questionnaire to evaluate the risk of OSAS were applied to participants.

Results: It has been determined that 10–12.5% of healthy pregnant women, 34–45.4% of pregnants with chronic diseases and 20.6–23.3% of all pregnant women had a high risk of OSAS, the pregnants with chronic disease compared to healthy pregnant women had statistically significant higher risk of OSAS. The risk of OSAS was found to be significantly higher especially in pregnant women with hypertension and diabetes.

Conclusions: OSAS can lead to the adverse consequences in pregnancy, should be questioned for all pregnants especially those with chronic diseases. Pregnant women with OSAS should be monitored more carefully in terms of diabetes and hypertension in antenatal care.     

Delay in Presentation,Diagnosis, and Treatment for Breast Cancer Patients in Jordan

Breast cancer is the most common cancer, and one of the leading causes of death for females in Jordan and many countries in the world. Studies have shown that delay in symptoms presentation, diagnosis or treatment would result in poor prognosis. There has been no published study from Jordan on delays in patient presentation, delays in diagnosis, or delays in treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for breast cancer patients in Jordan. This project was a cross‐sectional study on female breast cancer patients in Jordan. The total number of participants was 327. The proportion of patients with presentation delay, diagnosis delay, and treatment delay was 32.2%, 49.1%, or 32.4%, respectively. The main reported reasons for delay in presentation were ignorance of the nature of the problem (65.6%), limited/lack of knowledge that symptoms were suggestive of cancer diagnosis (16.7%), and misdiagnosis (16.7%). Predictors of delay and mean time for presentation, diagnosis, and treatment were identified. Our results reveal that breast cancer patients in Jordan are experiencing delays in presentation, diagnosis, and treatment. This could justify the advanced stages at diagnosis and poor outcomes for breast cancer patients in Jordan. We recommend revising the current early detection and down‐staging programs in Jordan.
