Prompt administration of appropriate antibiotic therapy is crucial in improving outcomes, particularly in cases sustained by multi-drug resistant strains. Although phenotypic antimicrobial susceptibility testing (AST) represents the gold standard to address antibiotics treatment, the long time required to obtained affordable results could negatively affect the prognosis. In contrast, rapid genotypic AST provide essential information for treatment and surveillance program. In order to evaluate the potential adoption of rapid AST in clinical routine, we compared the genotypic and phenotypic antimicrobial profiles of different K.pneumoniae strains, characterized by different expression of carbapenemases-encoding genes. A set of 109 strains of Cr-Kp were tested for the antimicrobial drugs by the automatized Vitek II system and, in parallel, to the new combination of β-lactams/β-lactamases inhibitors (BL/BLI) by Etest. An antimicrobial resistance index (ARI) was calculated for each strain, assigning each 1 or 0 points based on observed resistance/susceptibility, and dividing the total by the number of antibiotics tested. Kruskal-Wallis test, followed by Dunn's post hoc test (Bonferroni correction), were used to compare quantitative variables among resistance gene subgroups. We observed a higher ARI score in KPC/OXA-48 strains, similar profile in KPC alone and KPC/CTX-M groups and a significant lower resistance in no-carbapenemases-producing group. Same trend was observed in AST for BL/BLI. These preliminary results showed a close link between genotypic and phenotypic AST, supporting the adoption of rapid AST in cases of severe infections, ensuring to saving time and providing, the surveillance of MDR strains and improving stewardship programs.
This cross-sectional study assessed knowledge, attitudes and practices (KAP) of Italian Occupational Physicians (OPs) on Coronavirus disease 2019 (COVID-19) among meat/poultry processing plant workers (MPWs) (Summer season 2020). Data were collected through an online questionnaire including demographic characteristics, and items about COVID-19-related KAP in MPWs. A logistic regression was modelled in order to characterize explanatory variables of the outcome variable of having any professional experience as OP in meat/poultry processing industry. A total of 424 OPs (mean age 49.0 ± 9.1years; 49.5% males) participated into the survey. Despite a generally good level of knowledge on SARS-CoV-2 pandemic, OPs having professional experience with MPWs failed to recognize any increased risk for COVID-19 (Odds Ratio [OR] 0.162; 95% Confidence intervals [95%CI] 0.039-0.670), and were less likely to recommend periodical tests via nasal swabs (OR 0.168, 95%CI 0.047-0.605). On the contrary, they identified socioeconomic status of MPWs as a risk factor (OR 5.686, 95%CI 1.413-22.881), recommending cleaning interventions on changing rooms and canteens (OR 16.090, 95%CI 1.099-259.244). In conclusion, we reported a diffuse underestimation of the risk for COVID-19, that was alarmingly higher among professionals who should be more familiar with the specific requirements of MPWs. Some significant knowledge gaps were also clearly identified, stressing the opportunity for tailored educative interventions (www.actabiomedica.it).
The gold standard for the measurement of insulin secretion is the hyperglycemic clamp and for insulin sensitivity the hyperinsulinemic euglycemic clamp, respectively. A number of surrogate indices, derived from plasma glucose and insulin levels at a fasting state or after oral glucose load, have been proposed to estimate β-cell response, and the ability of β-cells to compensate for changes of insulin sensitivity by modulating insulin secretion (disposition index). Starting from the current recommendations for the annual screening of glucose dysregulation in patients with transfusion dependent β-thalassemia (β-TDT), this article summarizes the most frequently used indirect indices of insulin secretion and resistance derived from the oral glucose tolerance test (OGTT) and discusses the strengths and weaknesses of selected indices and the basic concepts underlying each method for the appropriate evaluation of glucose regulation. Basal indices for β-cell function and insulin sensitivity, albeit simple and cheap, have limited usefulness due to a high coefficient variation and the lack of data about response to glucose load. Therefore, measurement of indices during an OGTT, despite being costly and time-consuming, is suggested since it can detect, even subtle, dynamic changes in insulin secretion and glucose handling. In patients with β-TDT, the indices derived from OGTT may offer an additional factor to evaluate the efficiency of iron chelation therapy and detect patients who may need intensification of iron chelation therapy and/or pharmacological intervention.
Prosthetic replacement with reverse shoulder arthroplasty (RSA) is commonly indicated for complex proximal humerus fractures (PHFs) in elderly patients. Aim of this study was to evaluate the clinical and radiological outcomes of RSA performed for comminuted PHFs, without periprosthetic reconstruction of the tuberosities. Our hypothesis was that a large diameter glenosphere could ensure satisfactory RSA mobility and stability, regardless of tuberosity removal. We selected 32 patients (4 men, 28 women) with comminuted PHFs who underwent RSA with tuberosity excision and implantation of a 44-mm glenosphere between 2009 and 2015. Active range of motion (ROM), stability, Constant-Murley Score (CMS) (1) and Subjective Shoulder Value (SSV) (2) were assessed one year and four years after surgery. Clinical and radiological information were collected for 23 patients (72%). At one-year follow-up, active anterior elevation (AE) was 96±28 degrees, external rotation with adducted arm (ER1) 9±7 degrees, external rotation with abducted arm (ER2) 14±10 degrees, internal rotation (IR) to L4; CMS was 56±10 and SSV 65±22. Clinical assessment at 4-year follow up showed a decrease in active ROM (AE was 88±20 degrees, ER1 8±2 degrees, ER2 12±10 degrees, IR to L4), CMS (52±9) and SSV (62±8). No RSA dislocation occurred during the study. In 4 patients, grade I glenoid notching without any sign of component loosening was observed 4 years after surgery. A large diameter glenosphere does not ensure results comparable to those achieved after RSA with tuberosity reconstruction. However, the 44-mm glenosphere was effective in preventing RSA instability.
Avascular necrosis (AVN) of the humeral head is a relatively frequent complication after proximal humerus fractures (PHF). There are many factors related to the risk of developing AVN, with fracture complexity being one of the most relevant. Aim of the present study is to evaluate the correlation between different classification systems and the risk of post-operative AVN in patients treated with locking plate fixation for Neer 3 and 4-part PHFs. The study population included 44 patients (F:M 2:1, mean age 62) treated between December 2014 and April 2019. Fractures were classified according to Neer, Russo and Lego classifications and Hertel's criteria. AVN was established on postoperative radiographs after a minimum follow-up of 6 months. The odds ratio (OR) for AVN for each classification subtype was calculated. The incidence of necrosis was 11%. Significant association with AVN was found for Neer 4 part (OR=8), Russo IVB (OR=4), Lego pattern 12 (OR=8) and in presence of 3 mayor Hertel's criteria (OR=15,5). There is a significant association between AVN and Neer 4 part, Russo type IVB and Lego pattern 12 fractures. AVN risk is also significantly higher in presence of 3 major Hertel's criteria.
Nocturnal enuresis (NE) is a common condition in the pediatric age. NE is defined as an intermittent bedwetting with any frequency while sleeping in children. NE is classified into primary form (patient never had achieved nocturnal urinary control) or secondary form (children with a period of 6 consecutive months of night-time urinary control before incontinence, which is generally associated with organic or psychological causes). Moreover, NE could be monosymptomatic (MNE) or non-monosymptomatic (NMNE), depending on the presence of daytime incontinence or any other lower urinary tract symptoms (LUTS). We report a 7-year- old female with a history of recent onset of sphincter troubles and recurrent low urinary tract infections. She presented urinary urgency associated to daytime incontinence, bedwetting almost every night in the previous 3 months and sometimes encopresis. The physical and neurological examination was silent, no psychological or social problem intercurred. As first approach, she was treated with deamino-delta-D-arginine vasopressin (dDAVP) 120 mcg associated with oxybutynin 5 mg and educational therapy, for 3 months without benefits. So, she underwent a magnetic resonance imaging (MRI) of the spinal cord, that highlighted the presence of hydrosyringomyelia from D6 to D10, lipoma of the terminal filum and the presence of synovial cyst between L5-S1. This case remarks that in secondary NMNE, any possible organic cause must be investigated.
With the rising prevalence of obesity worldwide, it is becoming imperative to detect disturbed glucose metabolism as early as possible in order to prevent type 2 diabetes (T2D) development. The present retrospective observational study aimed to evaluate the relationship between BMI and glucose metabolism, insulin secretion and sensitivity indices, derived from glucose tolerance test (OGTT), in β -TM female patients who were overweight (BMI 25-29.9 kg/m2) and follow its outcome over time. Eleven overweight and 11 females with ideal weight and β -TM, matched for age, were recruited. OGTT was undertaken and different indices for β-cell function, insulin sensitivity and insulin secretion were calculated. At first evaluation, 7 of 11 overweight β -TM patients (63.6%) and 3 of 11 normal weight β-TM patients (27.2%) had glucose dysregulation (GD) during OGTT. Overweight patients with β-TM had increased HOMA-IR and QUICKI indices associated with decreased Matsuda WBISI index. The mean ± SD duration of follow-up was 4.5 ± 1.2 years. At last observation, 2/11 overweight patients had developed T2D (18.1%). In patients with normal weight, GD increased from 3/11 (27.2%) to 5/11 (45.4%), but none developed T2DM. The difference between SF at first and last observation (1,220 ± 702 vs.1,091 ± 454 ng/mL; P: 0.61) was not significant. Overweight seems to be an additional risk factor for the development of GD in β-TM patients. This is particularly important in clinical practice, due to the lack of appropriate guidelines dedicated to this group of patients.
Current data suggest little to no possibility of original COVID-19 transmission in pregnant women to the fetus during pregnancy or childbirth. Warning with Omicron new variants has decreased. A clinical case of a SARS-CoV-2 virus transplacental infection of a newborn, born at the end of 2022, from a mother who tested positive for Sars-covid-2 and positive IgM SARS-CoV-2 anti-virus. The newborn tested positive for SARS-CoV-2 12 hours after birth, and was clinically symptomatic after three days, an increase in IgM antibodies was not found, although the virus was identified in the urine samples through molecular tests. The insufficient time to determine the presence of antibodies and the immune system's state of immaturity can explain the lack of IgM in the newborn's blood at 14 days after birth. The Omicron SARS-CoV-2 keeps provoking infections among newborns, especially if the mother contracts it during the third trimester. The host response is most likely influenced by the newborn's peculiar state of immune immaturity. Just before birth, a positive nasal swab and the presence of a positive urine examination confirmed the diagnosis of intraplacental exposure. Research on the virus through molecular tests of urines can represent an additional technique when an aetiological framework of the infection is necessary and a distinction between congenital and post-natal forms.
Anti-recoverin antibodies are typically found in cancer-associated retinopathy or autoimmune diseases. We present a case of anti-recoverin positive cerebellar syndrome without any signs of malignancy or retinopathy. The patient was treated with steroids and intravenous immunoglobulins, resulting in improvements in both cognitive and motor symptoms.
Existing follow-up data after MIS-C is limited. to investigate the long-term consequences in children who have undergone MIS-C. The retrospective study included 93 children. The identified changes were divided into the following periods: occurred within first 6 months, 1 year, 2 years, and more than 2 years after MIS-C. Besides, 31 children underwent prospective immunophenotyping of peripheral blood and the determination of cytokines during the acute period of the disease and after discharge. Outpatient monitoring events included pneumonia (9.6%), somatic disorder syndrome (11.8%), visual impairment (7.5%), joint damage (6.6%), weight changes (2.2%), and MIS-C recurrence (2.2%). A study of the cardiovascular system showed a statistically significant decrease in the frequency of the right and left heart dilatation, left ventricular dysfunction, pericarditis, pulmonary arterial hypertension, coronaritis, mitral regurgitation. But at the same time an increase in pulmonary and tricuspid valve regurgitation and arrhythmias compared with the acute period was detected. Most of the changes took place within first year of observation. Immune profiling showed reconstitution of CD3, CD4 T-lymphocytes, NK-cells, maintenance of a high relative value of CD8, reduction of CD19+ B-cells, expression of CD3-HLA-DR+, CD25, CD279, CD95. After the history of MIS-C, children in the long-term follow-up had various somatic disorders and disease recurrence. Most patients (64.1%) showed subclinical signs of myocardial involvement within first year of observation. Low expression of CD95 may justify an certain role in the pathogenesis of the disease.
Simultaneous medial and lateral tibiofemoral osteoarthritis (OA) could be treated with bi-unicompartmental knee arthroplasty (Bi-UKA) as an alternative to total knee arthroplasty (TKA). The present systematic review aims to assess if simultaneous Bi-UKA is a feasible option for treating medial and lateral tibiofemoral OA. A comprehensive search of PubMed, MEDLINE, Cochrane Library, and Google Scholar was performed to find studies that reported on the outcome of simultaneous Bi-UKA for both medial and lateral tibiofemoral OA. Seven studies were considered eligible for inclusion in the present systematic review. Intraoperative fractures occurred 8 times. Overall, there were 22 revisions of the prosthetic components for any reason with a survival rate that ranged from 83 to 100%. Of these, 16 revisions were for the aseptic loosening of the prosthetic components. Out of 302 surgeries, three were revised due to symptomatic OA progression in the patello-femoral joint. All clinical scores improved at the latest follow-up compared to preoperative values. Moreover, there were no differences in clinical scores of Bi-UKA compared to unicompartmental knee arthroplasty (UKA), or medial UKA plus patello-femoral prosthesis. Whereas, compared to TKA, Bi-UKA patients had comparable or superior scores. Finally, the Bi-UKA group had a significantly shorter hospital stay compared to the TKA group. The use of simultaneous Bi-UKA is a valid option to address bicompartmental knee OA in selected patients with low intraoperative fracture rate, low revision rate, satisfactory clinical outcome, and fast recovery.
A cervical spinal cord injury often affects hand control, causing ineffective grasping and handling functions, with a negative impact on patient's independence and quality of life. Literature recognises scientific evidence only for surgical or instrumental re-education approaches. The purpose of this study is to present the "functional hand" protocol, a physiotherapy tool that, to date, represents a good clinical practice but has no supporting literature. a longitudinal-single cohort study was conducted at Spinal Unit- Azienda Usl Piacenza. Patients with spinal cord injury at C5-C7 neurologic level, older than 18 years, with correct comprehension of Italian language were recruited. All patients were evaluated with Action Research Arm Test (ARAT) scale to state hand functionality; positive/negative history of Functional Hand protocol was deducted by physiotherapy discharge letters on first spinal unit hospitalisation. six patients were involved in the study; three of them had a positive history of protocol application. ARAT scores differences showed that patients who underwent functional hand protocol had a lower impairment, a better ability to produce cylindrical and cuboid sockets. Functional hand protocol reached a preliminary evidence as effective tool to improve hand recovery in tetraplegic patients; future studies should confirm these conclusions on larger samples, and verify protocol effectiveness in addition to other treatment strategies (functional electric stimulation/ transcranial direct current stimulation/robotic assisted therapy).
Avascular necrosis (AVN) is a debilitating complication in sickle cell disease (SCD) patients, and its management is usually challenging. This study aims to evaluate the clinical and epidemiological features and therapeutic options of AVN in sickle cell patients in Qatar. A cross-sectional study was conducted on a 49 SCD patients who were diagnosed with AVN and attended the hematology clinic at the National Center for Cancer care & research, Hamad Medical Corporation, Qatar between Jan-2011 to Jan2021.  Results: Forty-nine adult patients with SCD who were diagnosed with AVN were studied. The median age of the study population is 32 years, and the median age at the first AVN diagnosis was 26 years (range: 11-44 yr.). 37 (75.5%) patients suffered from multiple joints AVN while 12(24.5%) had single joint involvement. 31 (63.3%) patients had bilateral hip AVN and 18 (36.7%) had shoulder involvement. 30 patients (61%) were on Hydroxyurea treatment. Based on FICAT and Alert classification of AVN, 57 % of patients had stage III and above at first diagnosis. 20 (40.8%) were managed with a conservative approach, 11 (22.4%) received hyperbaric oxygen with good response, 6(12.2%) underwent hip core decompression and 12(24.5%) underwent hip replacement surgery. In SCD patients, AVN occurred more during the 3rd and 4th decades of life. The majority of AVN represented with advanced stage and had multiple joint involvements. We recommend adopting a low threshold of joint imaging for early detection and prevention of further complications.
Intraoperative femoral fracture is a rare but growing complication of primary total hip arthroplasty. We aimed to present an uncommon related case, assessing also the role of malnutrition and osteoporosis. We discuss the case of a 49 years old male patient, malnourished and osteoporotic, with an intertrochanteric, multifragmentary, inveterate fracture, that happened three months before. During the prosthetic surgery, a supracondylar fracture occurred. We synthesized it with a 13 holes LISS plate, 7 distal screws and 3 proximal cerclage wires. The leg was immobilized to 0° for 3 weeks and the load forbidden for 3 months. Calcium, Albumine, Total Proteins, Osteocalcin and Vitamin-D levels were below the normal range. Teriparatide was administered for 6 months. Global investigation of the patient's nutritional status is recommended before joint replacement and preoperative planning is mandatory to choose the adequate implant. Osteoanabolic therapy could be advisable to favor fracture healing.
Patients with multiple sclerosis (MS) are a high-risk group for neuropathic pain. to investigate predictors of neuropathic dysesthetic pain (NDP) occurrence and chronification in patients with MS during a 2-year observation period. After the exclusion criteria application and signing of informed consent, we recruited in the study 241 patients among which 23 patients prematurely stopped participating in the study. During the 2-year observation period, new NDP was diagnosed on the PainDETECT questionnaire (>18). Patients with newly diagnosed NDP were examined at baseline, in 1, 3, and 6 months depending on pain duration. The socio-demographic, neuropsychological, cognitive, sleep quality, and clinical characteristics of patients were evaluated at the beginning of the study and updated at baseline examination in cases of newly diagnosed NDP. Over a 2-year observation period, NDP occurred in 34 patients (15.6%). Out of 34 cases of newly diagnosed NDP, in 20 cases (58.9%) pain became chronic (lasting longer than 3 months). In the Cox proportional hazards multifactorial model, progressive types of MS were an independent predictor of NDP occurrence (hazard ratio 2.60; 95% confidence interval, 1.30-5.18; p=0.01). In the multifactorial logistic regression analysis, subclinical depressive disorders (according to Hospital Anxiety and Depression Scale) were identified as an independent predictor of NDP chronification (odds ratio 7.14; 95% confidence interval, 1.12-45.59; p=0.04). In MS predictors of NDP occurrence are progressive types of MS, whereas predictors of NDP chronification are subclinical depressive disorders.
Acetabular revision surgery is the most challenging aspect in hip prosthetic. There is lack of consensus on the optimal method of reconstructing the acetabular defects. The aim of this systematic review is to take stock of the state of the art on the options available and highlight which type of construct is the most reliable in usual clinical practice. The reporting of this systematic review was guided by the standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis 2020 Statement.Electronic search of MEDLINE was performed from 1991 up to April 2021 to identify relevant studies for this review.  Discussion: various surgical techniques have been adopted and proposed to treat acetabular bone defects: cemented cups, large-sized non-cemented acetabular cups, higher positioned cups, reinforcement rings, cage, oblong cups, custom triflange implants, high porous metal cups and augments. Bone defect defines the type of components to be implanted and among those, outcomes are various depending on the study taken into account, the component used and the degree of initial bone defect. In acetabular revision surgerythe use of TM cups and augment is a valid option in presence of major bone loss and pelvic discontinuities. In clinical practice the use of TM components replaced rings, while the cup-cage implant replaced conventional cages. TM augments and cups can be considered as the most promising technique in the reconstruction of wide acetabular defects, while the use of cages can be considered as a valid option in the elderly population.
A 53-year-old man complaining of pain in the right hypochondrium underwent an abdominal ultrasound that showed a left adrenal lesion. Further instrumental investigations (CT and MRI, both with contrast medium) were performed which diagnosed an adrenal ganglioneuroma, confirmed by the histological examination. The patient also underwent an endocrinological examination. The treatment was surgical and consisted of an adrenalectomy through video-laparoscopic access. Adrenal ganglioneuromas are rare tumors but well described and known in the literature. For this reason, this case report has primarily an educational purpose: the totality of the data collected (clinical, laboratoristic, instrumental, and histopathological) constituted a multidisciplinary case, with the focus on imaging.
Children born small for gestational age (SGA), defined by a birth weight and/or length standard deviation score (SDS) of < -2 based on an appropriate reference population, represent a diverse group due to multiple underlying causes of reduced growth. This classification results in a heterogeneous patient cohort. SGA children are prone to endocrinological and metabolic issues not only in childhood but also extending into adolescence and adulthood. This population faces elevated health risks, including persistent short stature, premature adrenarche, pubertal development alterations, neurocognitive problems, and metabolic syndrome. Insulin resistance emerges as a pivotal factor c nht6j7ikontributing to these metabolic complications, prominently featuring obesity, insulin resistance, hypertension, and an increased risk of type 2 diabetes mellitus in adulthood. These medium- to long-term complications significantly impact their quality of life. Growth hormone (GH) therapy for short children born SGA facilitates height normalization throughout childhood, adolescence, and into adulthood. Catch-up growth, however, correlates with heightened risks of obesity, insulin resistance, and metabolic syndrome. Conversely, those without catch-up growth tend to exhibit pronounced short stature and cognitive dysfunction. Given these determinants, comprehensive management and clinical monitoring of SGA children should commence in the neonatal period and extend into adulthood. Recognizing and addressing these challenges early in life can mitigate the long-term impact on health and well-being, emphasizing the importance of a lifelong approach to their care.
Congenital heart disease (CHD) is an abnormality in the structure or function of the cardio-circulatory system present at birth and the ventricular septal defect (VSD) is the most common CHD in children. This study aimed to determine any differences in the histological structure of primary teeth between both healthy children and those children with ventricular septal defects in Erbil City. Methods enrolled children were divided into two groups. Group I (control) & group II (CHD) aged between 6-10 years old. A total of 44 children were collected, (22 children) in each group. Enamel, dentin, and odontoblast layers were examined histologically. Unpaired t-test used for statistical analysis. Results: The histopathological sections showed a significant difference in enamel, dentin, and odontoblast layer thickness (255.8 ± 41.68- 406.4 ±46.39), (1156 ± 116.0 - 1320 ± 117.4) and (29.74 ± 7.66 -41.38 ± 12.06) respectively, with p values (P < 0.0001) for enamel and dentin layer, and P < 0.0004  for odontoblast layer. A study of the images in the CHD group showed that the tooth tissue lost its integrity and cohesion in some places, and the thickness of the enamel and dentin layer in this group was significantly reduced compared to group I.  Tissue loss in enamel, pulp, and dentin cell were observed. Also, connective tissue layers in the pulp were disrupted. Conclusions: CHD can alter the natural structure formation of primary teeth. Histologically, enamel, dentin, and odontoblasts layer thickness reduction are found in primary teeth in children with ventricular septal defects.
Non-transfusion - dependent β-thalassemias (NTD-βThal) can cause iron overload and serious iron-related organ complications as endocrine dysfunction, including glucose dysregulation (GD). We retrieved data of all NTD- β Thal patients referred consecutively to a single Outpatient Italian Clinic from October 2010 to April 2023. All patients underwent a standard 3-h oral glucose tolerance test (OGTT) for analysis of glucose homeostasis, insulin secretion and sensitivity/resistance (IR), using conventional surrogate indices derived from the OGTT. The collected data in NTD- β Thal patients were compared to 20 healthy subjects. Seventeen of 26 (65.3 %) NTD- β Thal patients (aged: 7.8 -35.1 years) had normal glucose tolerance, 1/26 (3.8 %) had impaired fasting glucose (IFG), 5/26 (19.2 %) impaired glucose tolerance (IGT), 1/26 (3.8%) IFG plus IGT and 2/26 (7.6%) plasma glucose (PG) level ≥155 mg/dL 1-h after glucose load. GD was observed exclusively in young adult patients; none of them had diabetes mellitus (DM). These findings were associated with a low insulinogenic index (IGI) and oral disposition index. HOMA-IR and QUICKI were not significantly different compared to controls. Interestingly, in young adult patients, ISI-Matsuda index was statistically higher compared to the control group, suggesting an increased insulin sensitivity. This study reported a high prevalence of GD in young adults with NTD- β Thal. The documented reduction of IGI rather than the presence of IR, indicates reduced insulin secretory capacity as the pathophysiological basis of dysglycemia that may represent a novel investigational path for future studies on the mechanism(s) responsible for GD in NTD- β Thal patients.
