Atypical Resection

Hepatic lobectomy was performed in 17 patients for tumor (15 cases) or for hepatic cyst (2 cases). With regard to the hepatic lobes resected, there are 2 left lobectomies, 3 right, 9 right extended to the medial segment of the left lobe, 1 atypical resection of the right lobe and 1 of the left lobe, and 1 total hepatectomy followed by hepatic homotransplantation. In 9 patients, laparotomy showed that resection was not possible and they are used as controls.Blood samples were drawn every 30 minutes during operation, every day or every other day during the two post-operative weeks.Increased fibrinolytic activity and positive ethanol gelation tests are frequent but transient during surgery. However hemorragic problems are not encountered if hepatectomy is regulated. Routine administration of PPSB, antifibrinolytics or heparin does not seem to be required.Variations of clotting factors and antithrombin III are observed during the days following surgery.

Foregut Cyst

Ciliated hepatic foregut cyst (CHFC) is a rare lesion which originates from detached hepatic diverticulum or from detachment and migration of buds from the esophageal and bronchial regions of the foregut which subsequently get entrapped by the liver during the early embryonic development of the foregut. CHFCs are mostly seen in adults and are rarely reported in children, with only about 10 cases reported in this age group. Hereby, we present two cases of CHFC in two 3.5-year-old boys; one of them had cystic lesion at medial segment of left lobe of liver (common site), and in the other one it was located at right lobe of liver (less common site). Histologically, both cysts had four layers composed of inner ciliated, pseudostratified, columnar epithelium; subepithelial connective tissue; smooth muscle layer; and an outer fibrous layer.

Цель исследования - изучение влияния резекции печени (РП) на аммиакэкскретирующую функцию почек при хроническом тетрахлорметановом гепатите. Методика. Опыты выполнены на 265 беспородных белых крысах (самках) массой 180-220 г. Хронический гепатит воспроизводили подкожным введением 50% раствора тетрахлорметана (CCl) на оливковом масле (0,1 мл/100 г массы тела, через сутки, c двумя двухнедельными перерывами между 6, 7 и 13-14 инъекциями). На 65-е сут. (последние) введения тетрахлорметана, удаляли часть левой доли печени (15-20% массы органа). На 3-и, 7-е и 14-е сут. после РП или лапаротомии («ложнооперированные» животные) в почках, артериальной и венозной крови, моче исследовали содержание аммиака, глутамина и мочевины. Результаты. Прогрессирование эндогенной аммиачной интоксикации после РП на фоне тетрахлорметанового гепатита сопровождается повышенной экскрецией аммиака почками. Однако это не устраняет артериальную гипераммониемию и не предотвращает накопление почками аммиака. Инкреция глютамина из почек в кровоток прекращается. К 14-м сут. послеоперационного периода возрастает потребление глютамина из артериальной крови, что приводит к его накоплению в почках. Стимулируя выведение мочевины из организма с мочой, РП одновременно активирует её образование в почках, с дальнейшим поступлением как в кровоток, так и в мочу. В зависимости от сроков послеоперационного периода это сопровождается изменением скорости реабсорбции мочевины в почках. Заключение. Полученные результаты свидетельствуют, что при РП на фоне тетрахлорметанового гепатита почки не предотвращают прогрессирование эндогенной аммиачной интоксикации, патологическое накопление аммиака и глутамина её клетками, но сохраняют способность принимать участие в регуляции повышенного содержания мочевины в артериальной крови. Mechanical (resection) or toxic (hepatitis) liver damage alone has an ambiguous effect on renal ammonia excretion during development of endogenous ammonia intoxication. The aim. The study investigated the effect of liver resection (LR) on renal ammonia excretion in chronic tetrachlorocarbon (CCl)-induced hepatitis. Methods. Experiments were conducted on 240 mongrel white rats (females) weighing 180-220 g. Chronic hepatitis was induced by subcutaneous injection of 50% solution of carbon tetrachloride (CCl) in olive oil (0.1 ml/100g body weight per day with two two-week breaks between injections 6-7 and 13-14). LR with removal of a part of the left lobe (15-20% of body weight) was performed on the 65th (last) day of CCl injections. The animals were examined on the 3rd, 7th and 14th day after LR or laparotomy (sham operation). Contents of ammonia (AM), glutamine (GN), and urea were measured in the kidney, arterial (AB) and venous ( v.renlis ) blood, and urine. Results. Progression of endogenous ammonia intoxication after LR associated with CCl-induced hepatitis and increased renal excretion of Am involves three mechanisms: 1) excretion of Am that is delivered to kidneys in the free form with AB; 2) stimulation of renal tubule secretion of Am that had formed in kidneys by deamidation of «arterial» Gn; and 3) contrary to rules, partial reabsorption of Am from collecting tubules into the blood. However, this does not eliminate arterial hyperammonemia or prevent accumulation of Am in kidneys. The stimulatory effect of LR in CCl-induced hepatitis on Gn incretion from kidneys to the circulation stops by the 14 day after surgery, and the accompanying increased consumption of Gn from AВ results in Gn accumulation in kidneys. LR stimulates urea excretion with urine and simultaneously activates kidney formation of urea, which further enters the bloodstream and urine. Depending on the postoperative period this is associated with changes in the rate of urea reabsorption in kidneys. Conclusions. In RP associated with CCl-induced hepatitis, kidneys cannot prevent progression of endogenous ammonia intoxication and pathological accumulation of ammonia and glutamine in kidney cells but retain the ability to participate in the regulation of the increased urea level in AB.

Bone disease is an important complication of hyperparathyroidism. We herein report a rare case of severe bone disease caused by primary hyperparathyroidism. A 33-year-old man presented with pain and restricted mobility in his right upper limb and right hip due to a fall 3 days previously. X-ray examination showed a fracture of the proximal and distal humerus. Computed tomography examination showed a supracondylar fracture of the right humerus, a fracture of the right femoral neck, a fracture of the right sciatic branch, and multiple brown tumors. Ultrasonography showed a 3.5- × 1.6-cm hypoechoic mass below the left lobe of the thyroid. The patient was diagnosed with primary hyperparathyroidism based on increased serum calcium and parathormone concentrations, pathological fractures, and multiple brown tumors. He therefore underwent bilateral lower parathyroidectomy. Pathological examination revealed a parathyroid adenoma. The patient recovered well after surgery and was followed up for 6 months with no symptoms of hyperparathyroidism. This case report suggests that clinicians should be aware of the possibility of severe bone disease secondary to primary hyperparathyroidism. Active and early diagnosis and surgical treatment are important in such cases.

Background. Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results. We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side of the absent lobe, left of the isthmus. Fine-needle aspiration biopsy revealed class V papillary carcinoma, but no lymph node metastases. Total thyroidectomy was performed for stage cT1bN0M0 carcinoma. Histopathology revealed normal thyroid tissues in the right lobe and isthmus, while the left lobe was absent. The mostly papillary carcinoma was adjacent to the truncated thyroid tissue, with a portion histologically consistent with poorly differentiated carcinoma. Conclusions. All previously reported cases of thyroid cancer complicated by hemiagenesis have represented carcinoma occurring within the present lobe. This case is extremely rare.

Pulmonary Hydatid Cyst

Abstract Background Cystic echinococcosis (CE)/hydatidosis is an important neglected parasitic zoonotic disease caused by the metacestode of Echinococcus granulosus s.l. The present study was designed to identify the pulmonary CE species/genotypes in isolated human underwent to surgery in our center in Southern Iran. Methods The study population of this study were all patients in Fars province who were admitted to Namazi Hospitals for pulmonary hydatid cyst surgery. Thoracic surgery was performed in the thoracic ward and the cyst/s was removed by open surgery via posterolateral or lateral thoracotomy. DNA was extracted from the germinal layer or the protoscoleces. PCR technique was performed using the cytochrome C oxidase subunit1 (cox1) gene, and the products were sequenced. Results A total of 32 pulmonary hydatid cyst samples were collected from 9 (28%) female and 23 (72%) male aged from 4 to 74 years old. A total of 18(56%) cyst/s were in the left lobe and 14 (44%) cysts in the right lobe. Sequence analysis of the cysts showed that 24 samples (75%) were E. granulosus s.s (G1-G3) genotype and 8 (25%) were E. canadensis (G6/G7) genotype. Conclusion E.granulosus s.s genotype was the most prevalent genotype followed by E. canadensis (G6/G7) genotype. There was no significant statistical correlation between cysts’ size, location, genotype strain, and patients’ age and gender.
