Acute vitreomacular traction syndrome after uneventful phacoemulsification

We prospectively evaluated 59 eyes following uneventful phacoemulsification and intraocular lens implantation with optic coherence tomography at one and seven postoperative days (POD). Acute vitreomacular traction was observed in two eyes (3.3%) at the first POD. Spontaneous resolution occurred in both eyes within one week. The temporary visual loss associated with acute vitreomacular traction syndrome may go unnoticed as visual acuity rapidly improves.     

A coronary aneurysm complicated by acute myocardial infarction. A case report

Coronary artery aneurysm (CAA) is a relatively rare disease that may cause angina, myocardial infarction, sudden death due to thrombosis, embolisation, or rupture. This report describes the case of a man aged 65 years old who had an anterior myocardial infarction due to left anterior descending artery (LAD) aneurysm. We attempted early percutaneous transluminal coronary angioplasty (PTCA) for treatment of acute myocardial infarction, but were not successful. He was then treated with intracoronary streptokinase. Serial coronary angiographies showed recanalisation and aneurysm on the LAD. The patient was operated on with coronary bypass surgery, and treated with an oral anticoagulant, nitrate, and blocker. He was well after one year of follow-up.     

Hypercalcemia syndrome. Coexisting hyperthyroidism, primary hyperparathyroidism and cancer of the gallbladder

Hypercalcemia is a frequent finding in clinical practice. All possible causes must be considered in a patient with hypercalcemia. The association between both benign or malignant thyroid disease and primary hyperparathyroidism is well recognized. Up to 65% with primary hyperparathyroidism have associated thyroid abnormality. Hypercalcemia has also been associated with many malignant conditions. But, it is rarely seen in digestive tract cancer, such as carcinoma of gallbladder. Hypercalcemia syndrome is an absolutely rare entity. It is coexisting with hyperthyroidism, primary hyperparathyroidism and cancer of the gallbladder.     

Alveolar echinococcosis of the liver: correlative color Doppler US, CT, and MRI study

Purpose: To determine and compare the imaging features of hepatic alveolar Echinococcosis using color Doppler US, CT, and MRI.

Material and Methods: Abdominal CT and MRI with and without contrast agents and color Doppler US were performed on seven patients with hepatic alveolar Echinococcosis. The lesions were evaluated for location, features of echogenicity, intensity and density, calcification, and vascular, hilar, and perihepatic involvement. The diagnosis was confirmed histopathologically in all patients.

Results: Six patients had solitary lesions, and one displayed multiple lesions. The lesions were generally seen as heterogeneous and hyper- or hypoechoic when imaged with color Doppler US, hypodense with CT, and hypointense with MRI, in comparison with the liver parenchyma. Calcification, central necrosis, and small peripheral cysts were observed in six, seven, and four patients, respectively. Vascular flow or contrast enhancement was not observed in any of the cases. A look at the respective advantages of each method reveals that calcification was best rendered visible via CT, small peripheral cysts with T2-weighted MRI, central necrosis with CT and MRI, and perihepatic invasion with multiplanar MRI. Vascular involvement was revealed by all methods.

Conclusion: Color Doppler US, CT, and MR imaging function extremely well as complementary methods in the diagnosis of HAE. Color Doppler US should be performed in these patients owing to its ability to efficiently detect the disease. Knowledge of imaging characteristics makes it possible to radiologically ascertain an early diagnosis.     

Determination of the usage of body mechanics in clinical settings and the occurrence of low back pain in nurses

This explorative study was designed to identify the usage of body mechanics in clinical settings and the occurrence of low back pain in nurses. The sample was composed of 56 nurses who work on the medical, surgical, emergency and intensive care units of a state hospital in Bolu, Turkey. Data collected through observation and interviews were evaluated using percentages, Chi-square and Mann-Whitney U tests. Results of the study showed that the majority of the nurses (87.5%) experienced low back pain at some time in their lives. Among the contributing factors for back pain, the relationship between wearing high heels, heavy lifting and back pain was significant statistically. According to the observations, the majority of the nurses used body mechanics correctly while sitting (53.6%), standing (58.7%), carrying (64.3%), pulling or pushing (79.4%), moving the patient to the side of the bed without an assistant (53.4%), moving the patient to a sitting position in bed (71.4%) and assisting the patient to a standing position (66.6%). However 57.1% of the nurses lifted and 82% extended incorrectly. The conclusion from this research was that some of the nurses do not use body mechanics correctly and the majority have low back pain.     

Sclerosing stromal tumor of the ovary: a case report

Sclerozing stromal tumor of the ovary is an extremely rare neoplasm occurring predominantly in the second and third decades of life. Most patients have menstrual irregularities and pelvic pain. Infertility and endometrial pathology have also been described. A 34-year-old woman presented with hirsutism and oligomenorrhea of three months duration. Ultrasound examination showed a heterogeneous right ovarian tumor consisting of predominantly solid tissue with several loculated cysts. On T2-weighted pelvic MR images, signal intensities of the cystic components were high and those of the solid components were heterogeneous, ranging from intermediate-high to high. Dynamic MRI marked early enhancement of solid components in the right ovary. The specimen obtained from endometrial curettage showed proliferative endometrium. Preoperative serum levels of tumor markers were in normal range: preoperative serum levels of testosterone (T) (2.42 ng/ml; normal for adult females 0.1-0.8 ng/ml) and dehydroepiandrosterone-sulphate (DHEA-S) (232.4 microg/dL; normal for adult female, 35-430 microg/dL) were measured and the T value was found increased. At laparotomy, a left ovarian mass was found attached to the right infundibulopelvic ligament and a left oophorectomy was performed. The mass was described as benign by frozen analysis. Definitive histopathological diagnosis was sclerozing stromal tumor of the ovary (SST). The histologic features included a pseudolobular pattern with focal areas of sclerosis and a two-cell population of spindled and polygonal cells. Immunohistochemical studies showed positive smooth muscle actin and negative cytokeratin, keratin, S100 and desmin. The T value decreased postoperatively (0.57 ng/ml).     

A neurosurgical view of anatomical evaluation of anterior C1–C2 for safer transoral odontoidectomy

An anatomical study for evaluation of anterior C1–C2. To provide essential anatomic data for safer transoral odontoidectomy. The surface dimensions of the atlas vertebra and the transoral approach for odontoidectomy have been described in detail. Anterior arcus of C1 must be drilled out to reach odontoid process for transoral odontoidectomy. The thickness of anterior ring of C1 has not been studied before. Sixty, dried adult atlas and 60 axis vertebrae and ten cadaveric craniocervical specimens were measured for the following: (1) bony drilling depth (BDD), the distance from the anterior wall of anterior ring of C1 to anterior wall of odontoid; (2) minimum drilling diameter (MDD), distance of minimum C1 anterior ring removal for odontoid resection on horizontal plane; (3) maximum bony drilling diameter (MBDD), distance of maximum C1 anterior ring removal for odontoid resection on horizontal plane. Lateral border of this diameter is limited by medial borders of the lateral mass; (4) the widest odontoid diameters (WOD) on coronal sections were measured. On 60 atlas and axis vertebrae, the BDD was 7.0 ± 1.2 mm on dry bones, the distance between the medial borders of the lateral mass (MBDD) was 16.1 ± 1.5 mm, and the WOD on coronal sections (WOD) was 9.8 ± 0.8 mm. On cadavers, the distance between the two edges of C1 anterior ring removal for odontoid resection (MDD) was 10.8 ± 1.1 mm and the WOD on coronal sections (WOD) was 10.1 ± 1.4 mm. An odontoid surgery through transoral approach is safe and feasible. A quantitative understanding of the anterior anatomy of C-1 and C-2 is necessary when considering transoral odontoid resection. In this study the authors define safe zones for anterior atlas and axis.     

Thyroid function tests in pregnant women with and without goiter in the eastern Black Sea region.

Maternal thyroid function was investigated in 29 pregnant women with goiter and 51 pregnant women without goiter in the eastern Black Sea region of Turkey, which is an endemic goiter area. Ten women with goiter and 10 healthy women without goiter were used as controls in the study. In all of the pregnant women, increased concentrations of total and free thyroxine, total and free tri-iodothyronine and thyroxine-binding globulin were found. Serum thyroid-stimulating hormone levels showed a decrease in pregnant women without goiter compared with non-pregnant women without goiter.     

Recurrent liver hydatid disease: when does it become symptomatic and how does one diagnose it?

BackgroundEchinococcosis is a zoonotic disease that mainly occurs in sheep-grazing areas. Recurrence of the disease and its diagnosis are relatively new areas of investigation due to the limited number of cases. The aim of this study was to evaluate the diagnosis of the symptomatic recurrent liver hydatid disease and the efficacy of abdominal ultrasonography (US).Materials and MethodsBetween 1988 and 2006, 412 patients with hydatid cyst of the liver were operated at Erciyes University Medical Faculty. We have considered a growing cyst at the original operative site or at the neighboring hepatic tissue as recurrence and investigated 38 of them for the recurrence of the disease (9.2%).ResultsThe recurrence usually occurred after 2 years. The majority of the cases were Types 2 and 3 (24 cases; 8 were Type 4 and 6 were Type 1) according to Gharbi classification. In 35 patients with recurrent disease approved after surgical exploration, US was successful in preoperative diagnosis (100%). Overall, the recurrence was demonstrated correctly by means of US in 35 patients (92.1%), and 23 of 26 patients (88.4%) were correctly diagnosed with the use of computed tomography. In our study, in the first 2 years after the operation, the success rate of US examination was 72.7%. The success rate of US rose up to 100% when the frequency of recurrence is highest.ConclusionBeyond 2 years after surgery, US examination alone might be enough for the diagnosis of symptomatic recurrent liver hydatid disease in patients with the suspicion of recurrence. Postoperative early US profile and annual US examination must be performed for at least 5 years to prevent misinterpretation in doubtful cases.
