Tumors of the lung and bronchi containing cartilage were known by a variety of names, chondroma, adenochondroma, chondromatous hamartoma and mixed tumor. This variation in nomenclatures explain the difference of illustration on the nature of these tumor. The concept pulmonary harmatomas are benign neoplasm and not developmental malformations, has gained wide acceptance in recent years. We have experienced four cases of intrapulmonary hamartoma which were all discovered during routine chest film check up for certificate of health and evaluation of other disease. One case is added further detailed histologic examination by electron microscopy. The age at time of the detection were 53 (male), 23 (male), 39 (female), and 56 (female) years old. The mean size is 4.3x3.7x3.4 cm. The locations were three left upper lobes and one right upper lobe. Lobectomy and wedge resecions were done. Cut surface showed promiment lobular structures, papillary configuration and multiple cleft like spaces. Predominant cellular components were cartilage but fat tissue in one of the four cases. Microscopic findings showed abundant hyaline cartilages bearing lobular configuration and overlying pseudostratified ciliated columnar and cuboidal epithelium. Fibromyxoid and undifferentiated cells were seen in myxoid and fatty tissue. Electron microscopic findings revealed stellate, undifferentiated mesenchymal cells bearing collagen formation, stellate smooth muscle and transition areas between undifferentiated mesenchymal cells and mature cartilage. Epithelial components were similar to terminal bronchiole and alveolar epithelium. These findings suggest the concept that intrapulmonary hamartoma represent a histologic specturm of benign mesenchymal neoplasms, which originate in peribronchial connective tissue.

With advancement of endoscopical instruments and technique, gallstone diseases can be managed with laparoscopic cholecystectomy which has rapidly and radically changed the surgical treatment of gallstone diseases. The ideas of laparoscopic surgery was introduced by Germany gynecologist Semm, in 1967 and was first performed by French surgeon Mouret, Dubois in 1987. Although many reports of early laparoscopic cholecystectomy were excellent, many surgeons want to know the surgical results of laparoscopic cholecystectomy are enough good to perform comparing with the conventional cholecystectomy, especially in early complications and late complications.

Journal of Veterinary Science 2021;22(5):e60-
Background:
Echocardiography is a primary tool used by veterinarians to evaluate heart diseases. In recent years, various studies have targeted standard echocardiographic values for different breeds. Reference data are currently lacking in Maltese dogs and it is important to fill this gap as this breed is predisposed to myxomatous mitral valve disease, which is a volume overload disease.
Objectives:
To establish the normal echocardiographic parameters for Maltese dogs.
Methods:
In total, 23 healthy Maltese dogs were involved in this study. Blood pressure measurements, thoracic radiography, and complete transthoracic echocardiography were performed. The effects of body weight, age and sex were evaluated, and the correlations between weight and linear and volumetric dimensions were calculated by regression analysis.
Results:
The mean vertebral heart size was 9.1 ± 0.4. Aside from the ejection fraction, fractional shortening, and the left atrial to aorta root ratio, all the other echocardiographic parameters were significantly correlated with weight.
Conclusion
This study describes normal echocardiographic parameters that may be useful in the echocardiographic evaluation of Maltese dogs.

Patients with Peutz-Jeghers syndrome often suffer from complications of polyps, such as intussusception, bowel obstruction, and bleeding. Another major problem of these patients is malignancy through the hamartoma-adenoma-carcinoma sequence. If the complications and the cancer risk of small intestinal polyps are to be reduced, early detection of these polyps and a polypectomy are important. Traditionally, a small bowel series, small bowel enteroclysis, and conventional endoscopy have been used for the proper evaluation, and management of polyps. Recently, several reports showed the advantages of enteroscopy and intraoperative endoscopy for achieving a more complete polypectomy of the small intestine. However, CT enteroclysis, which has been introduced as a reliable, less invasive, and tolerable diagnostic tool for small intestinal disease, may be useful for the evaluation of patients with gastrointestinal polyposis. We report the case of a patient with Peutz-Jeghers syndrome who had small-bowel polyposis and a rectal adenocarcinoma and who underwent preoperative CT enteroclysis and intraoperative endoscopy.

BACKGROUND: Postoperative sore throat (POST) is considered a usual complication after tracheal intubation, especially, thyroid surgery. Gabapentin is a widely studied multimodal perioperative drug, which can be used to treat acute postoperative pain. The primary endpoints of this study was a reduction of the incidence of POST at rest and during the swallowing movements after thyroid surgery. And the second endpoints was a reduction of the intensity of the POST after thyroid surgery. METHODS: Seventy-one patients that underwent elective thyroid surgery received either gabapentin (Neurontin(TM) 600 mg) or placebo, orally, one hour before anesthesia. The VAS scores and incidences of POST and adverse effects were determined at 1 hr, 6 hr, 12 hr, and 24 hr after surgery at rest and during swallowing movement. RESULTS: The gabapentin group (N = 36) showed a lower incidence of POST than the placebo group (N = 35) (47% vs. 78%, P = 0.038), and had significant lower VAS score at 6 and 24 hours after surgery in the resting state. However, during the movement, no intergroup differences were found in terms of the incidence of POST (83% vs. 91%, P = 0.305) or VAS score. Furthermore, no significant difference was observed between the two groups, in adverse effects. CONCLUSIONS: Gabapentin (Neurontin(TM) 600 mg) administered 1 hr before anesthesia reduced the intensity and incidence of POST during the resting state without a significant adverse event, during the 24 hr after thyroid surgery. However, gabapentin did not reduce the intensity and incidence of POST during the swallowing movement.

Splenic artery embolization plays an important role in the management of various medical and surgical conditions that are non-traumatic in etiology, in addition to its well-established and widely discussed role in managing splenic trauma. In nontraumatic emergencies of catastrophic bleeding originating from the spleen or splenic artery, splenic artery embolization can be effective in achieving hemostasis as a definitive management, temporary stabilizing measure, or preoperative optimization technique. In addition to emergency clinical conditions, splenic artery embolization can be performed electively as an alternative to splenectomy for managing patients with hypersplenism.Herein, we report 6 cases of splenic artery embolization performed at our center to highlight its various indications. This article aims to demonstrate the role of splenic artery embolization in different clinical scenarios and the considerations behind the techniques employed through illustrative cases.

Organ transplantation from donors with immune thrombocytopenia (ITP), a condition involving the autoantibody-mediated destruction of platelets, is a topic of debate due to the potential for transplantation-mediated autoimmune thrombocytopenia (TMAT), a rare but potentially fatal complication. Previous reports have described transplants from deceased liver donors with ITP who had very low platelet counts and disease largely refractory to treatment. Here, we present the first case of living kidney transplantation from a donor with ITP who underwent preoperative treatment, with concurrent splenectomy performed to reduce the long-term risk of spontaneous hemorrhage.To ensure the safety of the procedure, we monitored perioperative rotational thromboelastometry parameters and platelet counts, leading to the normalization of the donor’s platelet levels. The recipient experienced an uneventful recovery of renal function without perioperative bleeding or the development of TMAT. Our report suggests that kidney transplantation from a donor with well-managed ITP is safe, and such a condition should not be considered a contraindication for donation.
