Background. To date, insertion torque value (ITV) and implant stability quotient (ISQ) obtained by the Osstell instrument are common clinical methods to assess the initial stability of an implant for ...a predictable loading procedure. The aim of this current study is to evaluate the ITV and ISQ as stability parameters as part of the decision-making protocol in the adoption of immediate loading in fresh extraction sockets. Materials and Methods. A total of 41 tapered implants were allocated into two groups: the test group (n = 11; 3 males and 8 females; mean age: 62.8 ± 10.7) which received 18 implants as type 1 fresh extraction sockets after teeth removal and the control group (n = 7; 4 males and 3 females; mean age: 65.4 ± 9.7) which received 23 implants placed in healed sockets for a period of at least 3 months. Both the ITV and ISQ data were recorded at the time of insertion (t0). Since ITV (test group) and ITV/ISQ (control group) values were useful for the immediate loading protocol, a screw-retained temporary crown was immediately loaded. ISQ values were recorded after a healing period of 4 months (t1). Results. ITV mean values at t0 in test and control groups were, respectively, 48.61 ± 15.39 and 70.47 ± 14.71, whereas ISQ mean values were 57.55 ± 1.93 and 72.86 ± 5.25, respectively, showing a statistically significant difference (p value < 0.001). ISQ mean values at t1 in either the test or the control group were 68.68 ± 4.20 and 74.54 ± 4.17, not showing a statistical difference. The implant survival rate was 100% in both groups, and no surgical and prosthetic complications were reported during the study. Conclusion. In conclusion, this study remarked the presence of a residual gap that influenced the ISQ during implant insertion in fresh extraction sockets making this parameter not sufficient for a conclusive decision in the immediate loading, whereas the ITV alone showed to be the best parameter for a final substantial decision.
Complex abdominal wall defects (CAWDs) can be difficult to repair and using a conventional synthetic mesh is often unsuitable. A biological mesh might offer a solution for CAWD repair, but the ...clinical outcomes are unclear. Here, we evaluated the efficacy of a cross-linked, acellular porcine dermal collagen matrix implant (Permacol) for CAWD repair in a cohort of 60 patients. Here, 58.3% patients presented with a grade 3 hernia (according to the Ventral Hernia Working Group grading system) and a contaminated surgical field. Permacol was implanted as a bridge in 46.7%, as an underlay (intraperitoneal position) in 38.3% and as a sublay (retromuscolar position) in 15% of patients. Fascia closure was achieved in 53.3% of patients. The surgical site occurrence rate was 35% and the defect size significantly influenced the probability of post-operative complications. The long-term (2 year) hernia recurrence rate was 36.2%. This study represents the first large multi-centre Italian case series on Permacol implants in patients with a CAWD. Our data suggest that Permacol is a feasible strategy to repair a CAWD, with acceptable early complications and long-term (2 year) recurrence rates.
FMS-like tyrosine kinase 3 (FLT3) is a receptor tyrosine kinase family member. Mutations in
, as well known, represent the most common genomic alteration in acute myeloid leukemia (AML), identified ...in approximately one-third of newly diagnosed adult patients. In recent years, this has represented an important therapeutic target. Drugs such as midostaurin, gilteritinib, and sorafenib, either alone in association with conventional chemotherapy, play a pivotal role in AML therapy with the mutated
gene. A current challenge lies in treating forms of AML with extramedullary localization. Here, we describe the general features of myeloid sarcoma and the ability of a targeted drug, i.e., gilteritinib, approved for relapsed or refractory disease, to induce remission of these extramedullary leukemic localizations in AML patients with
mutation, analyzing how in the literature, there is an important development of cases describing this promising potential for care.
Background: With the growing use of dental implants, there is an urgent need to determine a prosthetic placement protocol by assessing implant stability and monitoring healing. Implant Stability ...Quotient (ISQ) values are produced using dental non-invasive devices through resonance frequency analysis, considered as indicators for measuring primary stability (i.e., at implant placement), monitoring biological stability (osseointegration), and prosthetic loading. A systematic and detailed comparison of ISQ measurement devices, for a given patient population, is lacking in the literature. This aspect is the subject of the present work, with the devices being two that are widely used in clinical practice (Osstell® and Osseo®100). The aim of this study was to evaluate the reliability of ISQ measurement using two standard devices most commonly used in clinical practice and to highlight any differences when comparing measurements at undefined time intervals. Methods: We enrolled 50 patients (16 males and 34 females) with a mean age of 55.4 years, who indicated dental implant placement and met the inclusion criteria. The sample was divided into two equal groups based on bone density: A (D1–D2 bone density) and B (D3–D4 bone density); each had 25 patients with 40 implants. ISQ was measured using two devices: Osstell® and Osseo 100®, at different time points (A: three and B: four follow-ups). Results: All enrolled patients completed the study without adverse events; all implants placed were successful, with no implant failure. In each of the study groups, ISQ values increased gradually with increasing follow-up time, and there was no significant difference between Osstell and Osseo 100 values at follow-up times except for the T1 follow-up in group A. Temporal comparisons for the two devices revealed significant differences in T0 vs. T2 in group A, whereas significant differences existed in T0 vs. T1, T2, and T3 in group B. Our findings indicated that the overall effect significantly depended on bone density rather than on the device used to measure ISQ. Conclusion: Regardless of the devices used, the ISQ measurement effectively monitors healing after implant insertion and allows prosthetic load to be modulated according to the ISQ value, especially when prosthetizing implants placed in fine trabecular bone (D4 or regenerated bone).
Background
Although some studies have compared laparoscopic and hand-assisted laparoscopic splenectomy (HALS) in splenomegaly cases, no study has analyzed the differences between HALS and open ...splenectomy (OS). This study aimed to compare the HALS and OS techniques in splenomegaly cases.
Methods
This prospective study included 27 patients undergoing splenectomy for splenic disorders at the Department of General Surgery, Istanbul Medical Faculty between February and October 2007. Open splenectomy was performed for 14 patients and HALS for the remaining 13 patients.
Results
The end points compared included incision length, operative time, intraoperative blood loss, postoperative drain output and duration, postoperative pain scores, length of postoperative hospitalization, and perioperative complications. The authors found benefits of HALS over OS for incision length, postoperative pain score, postoperative drain output and duration, and hospital stay. The main advantages of the HALS technique over OS were less postoperative pain (
p
= 0.0002), shorter hospital stay (
p
= 0.004), and shorter abdominal incision (
p
= 0.012).
Conclusions
For splenomegaly, HALS significantly facilitates the surgical procedure and reduces the hospital stay while maintaining the advantages of OS such as tactile sense as well as easy and atraumatic manipulation of enlarged spleens.
Gastrointestinal tuberculosis(TB) is quite rare,representing only 3% of all extra-pulmonary cases.Blind gut and ileum are the most common gastrointestinal localizations,while appendix involvement is ...infrequent.Appendix involvement is usually related to symptoms of acute appendicitis since the caseous necrosis may lead to adhesions and surgical complications such as perforation.For this reason patients with suspected appendicular TB usually undergo surgery even without a secure diagnosis.In these cases,due t...
The congenital intrapericardial hernia is a rare kind of diaphragmatic hernia. It is due to an embryologic defect of the central tendon of the diaphragm, often accompanied by other congenital ...malformations. This work presents a unique case report in the literature of the congenital association between intrapericardial diaphragmatic hernia and epigastric hernia in an adult woman. In spite of herniation of the colon and omentum the patient was completely asymptomatic, requesting surgery for an epigastric hernia for aesthetic reasons. The defect of the diaphragm was sutured and the abdominal wall was repaired with a prosthetic mesh.
Sublay mesh repair seems to be the most effective method for treating incisional hernias (IHs). The aim of this study was to report our experience with retromuscular repair and self-gripping mesh for ...the treatment of midline IHs. In addition, we provided a systematic review of the literature regarding the use of this novel combination. All patients undergoing elective IH repair from June 2016 to November 2018 were included. The self-gripping mesh was placed in the sublay position. Demographic data, defect sizes, postoperative complications and follow-up durations were collected. A systematic review of the available literature was conducted in January 2020 using main databases. A total of 37 patients (20/17M/F) were included in this study, and the mean age and body mass index (BMI) were 58 years and 27 kg/m
2
, respectively. Minor complications occurred in six patients. Long-term follow-up demonstrated recurrence in three patients. Regarding the review, five publications were considered relevant. The highest complication rate was 28.6%, and the recurrence rate varied from 0 to 5.1%. This is the first review of the literature regarding sublay IH repair using a self-gripping mesh. The low rates of postoperative complications and recurrence in our experience and those reported by most of the reviewed articles demonstrate that this is a safe and effective method for repairing IHs.
