RESUMO
Background: Jacob's disease is a rare pathology characterized by elongation/ enlargement of coronoid process of mandible with formation of pseudoarticulation with zygomatic arch. It presents clinically as restricted mouth opening and is often misdiagnosed as temporomandibular joint pathology. Case Presentation: We performed cross sectional imaging and evaluation of Jacob's disease in a 14-year-old girl with restricted mouth opening, CT images including Multiplanar Reconstruction and Volume Rendered Technique revealed enlarged left coronoid process of mandible while open mouth CT images and MR images concluded the presence of joint between enlarged coronoid process and zygomatic arch. Conclusions: Coronoid process hypertrophy and Jacob's disease are important differentials which should be considered in evaluation of restricted mouth opening. We propose that apart from CT, MR imaging should be considered in such cases for better pre-operative evaluation of joint formation.

RESUMO
Background and Aims: The presence of gastric content increases the risk of aspiration during general anesthesia. Diabetic patients have delayed gastric emptying; however, despite adequate fasting because of diabetic gastroparesis these patients have a high risk of aspiration. This study aimed to compare ultrasound-guided measurement of residual gastric volume between diabetic and non-diabetic patients scheduled for elective surgery under general anesthesia. Methods: This prospective observational study included 80 patients divided into two groups of 40 diabetic patients with a minimum of 8 years history of diabetes and 40 nondiabetic patients aged >18 years, American Society of Anesthesiologists' physical status I-II kept with similar fasting intervals. Before induction of general anesthesia, gastric ultrasound was performed using standard gastric scanning protocol to measure craniocaudal (CC) and anteroposterior (AP) diameters followed by calculation of antral cross-sectional area (CSA) and gastric volume in semi-sitting (SS) and right lateral decubitus (RLD) position using curved array probe. The gastric antrum volume (GV) was classified as Grade 0, 1, or 2, and risk stratification for aspiration was done. The nasogastric tube was inserted after induction of anesthesia to aspirate and compare the gastric content. Results: In the semi-sitting position, the mean CC and AP diameters were 16.38 ± 3.31 mm and 10.1 ± 2.53 mm in the non-diabetic group and 25.19 ± 4.08 mm and 15.8 ± 3.51 mm in the diabetic group, respectively. In RLD, CC was 1.91 ± 0.38 cm and AP was 1.19 ± 0.34 cm in the non-diabetic group as compared to the CC of 2.78 ± 0.4 cm and AP of 1.81 ± 0.39 cm in the diabetic group. The calculated CSA of 318.23 ± 97.14 mm2 and 4 ± 1.1 cm2 in diabetic were significantly higher than 133.12 ± 58.56 mm2 and 1.83 ± 0.83 cm2 of non-diabetic, in SS (p < 0.0001) and RLD (p < 0.0001) positions, respectively. The GV of 15.48 ± 11.18 ml in the diabetic group was significantly higher than (-) 9.77 ± 18.56 ml in the non-diabetic group (p < 0.0001). Despite the differences in CSA and GV between diabetic and non-diabetic groups, both groups showed a low gastric residual volume (<1.5 ml/kg). The gastric tube aspirate in the non-diabetic and diabetic groups was 0.3 ± 0.78 ml and 1.24 ± 1.46 ml, respectively, and was statistically significant (p = 0.0006). Conclusion: Patients with long-standing diabetes showed higher gastric residual and antral CSA when compared with non-diabetic patients. The clinical significance of these findings needs further evidence for the formulation of specific guidelines for diabetic patients.
RESUMO
Osteochondromas are common benign tumors developing as an abnormal bony growth in the metaphyseal region. Being more of a developmental anomaly rather than a true neoplasm, they are usually found around the growth plates of long bones such as the knee, hip, and shoulder. These are typically managed conservatively if they are asymptomatic; however, they require excision in symptomatic patients. A 38-year-old woman presented with a huge swelling causing disfigurement measuring 16 × 16 cm on the left side of chest wall. Radiographs and computed tomography scan showed a bony outgrowth at costochondral junction of second rib which was in continuity with the periosteum. Excision via mediastinal sternotomy and left thoracotomy was done. Histopathological features corroborated with the radiological diagnosis of osteochondroma. Osteochondroma should be considered in the differential diagnosis of chest wall tumors. Rib is an extremely rare site of presentation. The cartilaginous cap becomes fully ossified and is lost in longstanding lesions. Huge tumors at such a location can cause irritation of adjacent viscera which can lead to pleural effusion or hemothorax; therefore, a cautious and logical approach to diagnosis is warranted for appropriate therapeutic management.
