Spontaneous bone regeneration of the reconstructed mandible in children is rarely reported. Most of previous reports discussed the role of periosteum in regeneration of bone. Alternatively, other factors such as mechanical stress and muscle attachment have also been implicated in spontaneous bone regeneration. This paper presents spontaneous-regeneration of the reconstructed mandible in a young girl, undergone a segmental mandibulectomy, and discusses the factors associated with regeneration based on the results of image examinations and Finite Element Analysis (FEA). The patient was an 11 year-old girl diagnosed as ossifying fibroma in the mandible. A segmental mandibulectomy and immediate mandibular reconstruction using a Ti-mesh tray and particulate cancellous bone and marrow was planned. The spontaneous-regeneration of the coronoid process was observed on the reconstructed mandible. On the CT slabs, the reattachment of the masseter and temporal muscle was confirmed. Before treatment, the transversal growth of her maxilla was asymmetrical. After the mandibular reconstruction and prosthodontic treatment, her maxilla grew back with bilateral symmetry. The occlusal loading on her mandible appeared symmetrically via an FEA. In addition, the stress was concentrated in the external oblique ridge, and the graft bone remodeled into the anatomical configuration. Through this case, it is suggested that the reattachment, the healthy growth of masticatory muscles, and the rehabilitation of oral function contributed to spontaneous bone regeneration and remodeling in the mandible, as well as the preservation of periosteum.

Background: A successful outcome in rhinoplasty should improve not only the aesthetic appearance of the nose but also the physiologic function of the nasal cavity. Nasal obstruction in many patients is caused by a deviated nasal septum and/or inferior turbinate hypertrophy. Preoperative proper diagnosis of these conditions is very important in planning cosmetic nasal surgery. Methods: Paranasal computed tomography reports of 119 patients requesting cosmetic nasal surgery were evaluated for the presence of septal deviation and inferior turbinate hypertrophy. Results: In 62 patients (52.10%) there was septal deviation with concave side facing the left nasal cavity and in 46 patients (38.65%) there was septal deviation with concave side facing the right nasal cavity. In only 11 patients (9.24%) there was no finding suggesting septal deviation. In 113 patients (94.96%) there was inferior turbinate hypertrophy. In only 6 patients (5.04%) there was no sign of inferior turbinate hypertrophy on paranasal computed tomography scan. Conclusion: Despite the fact that radiologic imaging is usually not a standard part of the workup in patients who are candidates for rhinoplasty, preoperative paranasal computed tomography is essential to detect the presence of concomitant pathologies like septal deformities, inferior turbinate enlargement, bullous middle turbinate and chronic sinusitis. Preoperative paranasal computed tomography is a very valuable method to assess internal nasal structures especially for plastic surgeons who do not have endoscopic instruments to examine nasal cavities.

Objective: Cloacal anomalies comprising rare pathological conditions which are observed in female fetuses and must be diagnosed at an early stage of pregnancy. Case Report: An antenatal patient, 23 years old, G3P2L2 was referred to our obstetric service with an ultrasound report of singleton pregnancy of 37 weeks with a septated cystic pelvic mass (7.4cm×7.3cm×8.3cm) in the fetal abdomen at the region of the bladder, atrioventricular septal defect and bilateral renal agenesis with severe oligohydramnios. The patient gave a normal birth with 1.6 kg baby body weight. The newborn had abdominal distension, ambiguous genitalia, and rectal Artesia with a single opening at the perineum. The newborn was placed in the neonatal intensive care unit where further diagnostic investigations were conducted. The neonate died on the 1 st day after 5 hours of life due to respiratory distress. Autopsy and karyotyping were done with proper verbal and written consent of the guardian. Conclusion: In our case, we reported a patient with a cloacal malformation with a cystic pelvic mass, fluid debris was seen on prenatal ultrasound which septate representing hydrocolpos of duplicating vagina. Thus, meconium and vaginal secretions accumulate in the compliant structure of vagina causing hydrocolpos which are rare condition rather than fetal ascites. Ultrasound with differential diagnosis at the early gestational stage can make a huge difference in decreasing such anomalies and early stage fetal mortalities.

Efficient repair and regeneration of alveolar epithelium after acute lung injuries are critical for pulmonary maintenance. Previous studies suggested alveolar type II cells (ATIIs) are progenitors in the adult lung and Alveolar Type I cells (ATIs) are terminally differentiated. However, recent studies develop fresh perspectives, which suggest ATIs may play more roles. Here we show that ATIs exhibit markedly enhanced proliferation capacity and express a set of ATIIs associated genes after treated with damaged lung milieus. These changed characteristics suggest ATIs generate phenotypic plasticity and exhibit dedifferentiated state. We identify KLF2 as a regulator of the module. Knockdown of KLF2 induces gene expression is consistent to those observed in milieu treated cells. These findings demonstrate the unanticipated plasticity of ATIs and suggest the molecular mechanisms controlling ATI-ATII plasticity which deserve more explorations.

Laparoscopic surgery has expanded its horizon tremendously. It has been the preferred approach in many operations. Massive subcutaneous emphysema is a rare unique complication of laparoscopic surgery. Here, we report two cases that developed progressive extensive subcutaneous emphysema after laparoscopic cholecystectomy. On reviewing the literature, we found that the incidence ranges from 0.43% to 2.34%. There are many risk factors that have been implicated for its development including; pneumo-peritoneum of more than 200 minutes, and insufflation of CO2 at pressure more than 15mm Hg, & PETCO2 more than 50 mmHg. Clinically, subcutaneous emphysema produces an unusual crackling sensation on palpation and graded into four grades according to the severity. The patients should be monitored closely for any cardio-respiratory changes and positive pressure ventilation should be continued until normocarbia is established and signs of respiratory distress & upper airway obstruction are absent. Although conservative supportive measures and close follow up are the only needed strategy in most of cases, however surgical drainage may be beneficial in some case. This achieved either incisions (infraclavicular or submandibular) or tube drainage through different techniques.

Purpose: Infections with Peptoniphilus harei are rare and no consens about treatment exists. Based on a case report, we report on our approach and make a review of the literature. To our knowledge, we are the first to be confronted with an infected epidermoid cyst in the facial area due to Peptoniphilus harei in its pure form. Material and Methods: A smear test for microbiological examination and for culture determination was taken intraoperative. Peptoniphilus harei could be detected by using the matrix-assisted laser desorption ionization time-off light mass spectrometry (MOLDI-TOF) method. A literature research showed only few documentations of an infection with this microorganism. Results: The post-operative course was uneventful. No antibiotics were needed. The microbiological examination detected Peptoniphilus harei as the only microorganism. Conclusion: The clinical impact of Peptinophilus harei is not clearly clarified due to poor data. Resistance cannot currently be considered as a problem. In our case report compared to the other case reports, no antibiotic therapy was initiated. For the detection of the causative microorganism, a microbiological sample is recommended.

Laparoscopic Sleeve Gastrectomy (SG) is the most commonly performed bariatric procedure in the management of morbid obesity. Post-operative splenic injury is a rare complication, and commonly seen as a delayed condition after surgery. We report the first documented case of spontaneous splenic rupture two days after laparoscopic sleeve gastrectomy.
