The Impact of Orthodontic Extrusion on Keratinized Gingiva.

Background and Objectives: The key factor that enables osteoblastic activity and the formation of new bone, as well as gingiva, during orthodontic tooth extrusion (OE) is the periodontal ligament. The reaction of periodontal tissues associated with changes in the gingiva is a part of orthodontic tooth displacement. The aim of this study was to examine the effect of OE on the width of the zone of the keratinized and attached gingiva, the position of the mucogingival junction, and the height of the interdental papillae in the region where the OE was performed as well as in the adjacent region. Materials and Methods: This research included 28 adult patients (both orthodontically treated and untreated). The treated group included 15 patients, in whom orthodontic extrusion of the upper or lower frontal teeth was indicated and performed. The untreated group included 13 patients, with no previous or undergoing orthodontic treatment. Patients with periodontal disease and periodontal pockets in the frontal region and patients allergic to iodine were excluded from the study. Gingivomorphometric measurements were performed on two occasions in three groups of teeth (24 extruded and 30 agonist teeth in the treated patients; 66 teeth in the untreated patients). Statistical analysis of the obtained data was performed using the software package SPSS version 26.0. Results: Orthodontic extrusion induced changes in the position of the mucogingival line and an increase in the width of the keratinized gingiva. There were no statistically significant effects on the depth of the gingival sulcus, the attached gingiva width, or the height of the interdental papillae. Conclusions: Orthodontic tooth extrusion has an effect on the periodontium in the observed region. Vertical orthodontic force, directed towards the coronal plane, affects the surrounding soft oral tissues.

Treatment of Open Bite Based on Skeletal Anchorage Using Extrusion Lever Arms and Class III Elastics.

A 26-year-old woman had a masticatory dysfunction, straight profile, retrognathic maxilla and mandible, and Angle's class I with a tendency to class III malocclusion on both sides, with bilateral posterior crossbites and a 4 mm anterior open bite. Orthognathic surgery and orthodontic camouflage with and without tooth extraction were considered as treatment options. The patient's preferred method of treatment was orthodontic camouflage without extraction. The transpalatal arch had been placed for the bilateral molars' derotation. After 3 months, the upper segmented fixed appliance was implanted to address the posterior crossbites in the premolar's region. One mini-implant was inserted into the anterior palatum after the transpalatal arch was removed, and a supporting device was attached to the first permanent molars to give indirect skeletal stability. Orthodontic treatment's active phase lasted 23 months, and all treatment objectives were achieved during that time: the desired facial profile, adequate occlusion, appropriate overbite, and overjet.

Splenic Abscess in an Adolescent due to Salmonella enterica Conservatively Treated with Ultrasound-Guided Fine-Needle Aspiration.

Background: Splenic abscesses are rare and potentially fatal. Diagnosis is often delayed due to vague symptoms, and laboratory findings are varying and often nonspecific. Ultrasound and computed tomography have a high sensitivity in detecting splenic abscesses. Splenectomy was previously considered the gold standard for treatment, but in recent years, a shift has been seen towards a more conservative approach, i.e., ultrasound-guided aspiration or drainage in combination with adequate antibiotics in selected cases. Case Report. A previously healthy adolescent complained of left-sided chest pain, pain in the left clavicular region for three weeks, and recent fever. Ultrasound and computed tomography demonstrated an intrasplenic abscess. The patient was successfully treated with two percutaneous fine-needle punctures and adequate antibiotics for six weeks. Salmonella enterica serotype Poona was grown from the aspirate. At one-year follow-up, the patient remained healthy without signs of recurrence. Conclusion: The present case report demonstrates that ultrasound-guided aspiration and subsequent treatment with antibiotics may be an effective alternative to splenectomy in patients with a splenic abscess.

[Omental infarction with omental torsion, arare condition very seldom suspected clinically].

This is a case report of an adult female with omental infarction caused by internal herniation and omental torsion. The patient, who had no previous surgical record, presented with three days of pain in the right upper quadrant. Ultrasound evaluation showed no signs of cholecystitis, after which an abdominal computed tomography confirmed the diagnosis. The patient underwent laparoscopic omentectomy, with an uneventful recovery. This case highlights the importance of radiological and surgical awareness of this rare condition.

[Acute appendicitis after colonoscopy].

Severe complications following colonoscopy are rare. This is a case report of a 44-year-old woman, who presented to an emergency department (ED) 24 hours following an uncomplicated colonoscopy performed in an out-patient clinic. Acute contrast-enhanced CT (CECT) was performed, showing acute appendicitis, which was later confirmed by a laparoscopy and histology. Weeks prior, the patient had been admitted to the ED with lower abdominal pain. On this occasion, CECT was performed, showing acute inflammation of the sigmoid colon.

[Radiology diagnostics and treatment of acute cholecystitis].

Acute cholecystitis (AC) is mainly caused by stones in the gall bladder. Although cholescintigraphy has the highest sensitivity (97%) and specificity (94%) for AC, ultrasound is the most commonly used technique in confirming the diagnosis. Laparoscopic cholecystectomy is the recom-mended treatment of choice; however, in high-risk patients percutaneous gall bladder drainage is an attractive alter-native approach to avoid lesions to the common bile duct. To avoid serious bleeding incidences, it is imperative to pause anticoagulation therapy prior to gall bladder drainage.

[Jejunal diverticulitis as the cause of acute abdomen].

We present two patients with jejunal diverticulitis. Diverticula in jejunum and ileum are very rare, occurring with an incidence of 0.07-2% in the gastrointestinal tract. They are often associated with unspecific symptoms as intermittent abdominal pain, nausea and diarrhoea. The treatment of mild diverticular disease is intravenous fluids and antibiotics. If there is an occurrence of peritonitis as a complication of jejunal diverticulitis, laparatomy may be indicated. Both of the patients received a conservative treatment with intravenous fluids and antibiotics with good response.
