Bilateral acute iris transillumination following a fumigation therapy: a village-based traditional method for the treatment of ophthalmomyiasis

Bilateral acute iris transillumination (BAIT) is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber and atonic pupilla. We report herein a 50-year-old female who presented with bilateral ocular pain, severe photophobia and red eyes. One month ago, a fly hit her eye, and she instantly complained of a discomfort and sensation of a foreign body in both eyes. She used a fumigation therapy, a traditional method for the treatment of ophthalmomyiasis. During follow-up examinations, intraocular pressures increased over 40?mmHg bilaterally despite maximal medical therapy, which necessitated trabeculectomy surgery with mitomycin. This is a typical BAIT case with no antecedent fluoroquinolone use or viral disease, but a fumigation therapy. There might be a possible relationship between BAIT and traditional fumigation therapy or this association might be coincidental, both of which need further evaluation.     

Clinical and Ultrasonographic Evaluation of Lower-extremity Vein Thrombosis in Behcet Syndrome: An Observational Study

Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes.All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed.Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS.Lower-extremity vein thrombosis associated with BS, when compared to LEVT due to other causes, had distinctive demographic and ultrasonographic characteristics, and had clinically a more severe disease course.     

The Anatomical Relationships of the Ocular Motor Nerves with an Emphasis on Surgical Anatomy of the Orbit

The surgical procedures directed to the orbit are invariably reported to be one of the most challenging procedures of the neurosurgery and it is very important to take measures to protect the ocular nerves. Many researchers have tried to identify safe approaches or safe regions in the orbit but the suggestions and results vary among published studies. The ocular motor nerves are under risk of injury during various approaches to the orbit. Simple but careful attention to potential variations in the origin and anatomical course of the ocular nerves and their relationships to the orbit may help to define “safe zones” during various approaches, thus, help to enhance clinical outcomes. The objective of this review, therefore, is to discuss the surgical anatomy of the orbit with special emphasis on oculomotor, trochlear, and abducens nerves and further emphasize their relationships with a surgical point of view during various approaches directed to the orbit.

A method for positioning the premaxilla during impression making for a patient with bilateral cleft lip and palate: a clinical report

In patients with bilateral cleft lip and palate (BCLP), orthodontic and facial orthopedic treatments alone occasionally fail to resolve problems because of the absence of alveolar and palatal hard and soft tissue or contraction resulting from previous surgical repair. Prosthetic reconstruction of the anterior maxilla is important for these patients. Patients with BCLP have premaxillary displacement in up to 3 dimensions. It may be difficult to make impressions without deformation. This clinical report describes a method for positioning the mobile premaxilla during impression making for a patient with BCLP.     

Ischemia-modified albumin in the diagnosis of acute mesenteric ischemia: a preliminary study

Ischemia-modified albumin (IMA) is a sensitive marker of myocardial ischemia, skeletal muscle ischemia, pulmonary embolism, and stroke. However, there are no studies showing whether IMA increases in mesenteric ischemia. The aim of this study was to determine whether IMA was elevated in acute mesenteric ischemia. This case-controlled study was performed in an emergency department of a university hospital. The measurement of IMA levels in patient plasma yielded means of 0.264 +/- 0.057 absorbance units (ABSU) in the thromboembolic occlusion of the superior mesenteric artery (SMA) group and 0.163 +/- 0.025 ABSU in the control group. When plasma IMA levels in the thromboembolic occlusion SMA group were compared with those in the control group, statistically significant increases in IMA were observed in the occlusion group (P = .003). Findings indicating that IMA may have a place in the diagnosis of acute mesenteric embolism were obtained in this preliminary study. Further prospective studies are needed to see if IMA is clinically useful in the early detection of thromboembolic occlusion of the SMA.     

Regulatory neuropeptides (ghrelin,obestatin and nesfatin-1) levels in serum and reproductive tissues of female and male rats with fructose-induced metabolic syndrome

Although, the exact mechanisms underlying the development of the metabolic syndrome (MetS) are not still completely understood, obesity, circulated peptide hormone levels and their interaction with genetic factors are considered largely responsible. The purpose of this study is to explore how the levels of ghrelin, obestatin (OBS) and NUCB2/nesfatin-1 (NES)/NUCB2 change in serum and the reproductive tissues of female and male rats with fructose-induced metabolic syndrome, and whether the levels of each hormone is correlated with the hormones involved with fertility. Experiments were conducted on 5-week-old Sprague–Dawley male and female rats assigned to either a control group or a MetS group. Controls were fed standard rat food and water ad libitum, while the MetS group was fed standard food with 10% (v/v) fructose solution added to their drinking water for 12 weeks with a 12/12 h photoperiod circle. Then, all animals were sacrificed after a one night fast. Peptides levels in the serum and reproductive tissues of rats were studied using the ELISA method while the immunoreactivity of reproductive system peptide hormones were shown by immunohistochemical staining method. Furthermore, the other biochemical parameters were measured using Konelab-60 equipment and infertility hormones were measured with Immulite2000. Fasting serum insulin, glucose, triglyceride, alanine aminotransferase (ALT), gamma glutamyl transpeptidase (GGT), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) levels were statistically significantly higher, and the amount of high density lipoprotein cholesterol (HDL-C) was significantly lower, in the MetS groups. Serum and tissue supernatant NES levels were significantly higher in the rats with MetS than the control group. Ghrelin, OBS and NES were expressed in the cytoplasm, concentrated around the apical parts of the epithelial cells in the reproductive tissues of the rats. The amounts of ghrelin were lower in the reproductive tissues of the animals with MetS, while NES levels in the same tissues increased. Obestatin also decreased, though not in the seminal glands.     

Peroneus quartus: prevalance and clinical importance

Introduction

The most common variant muscle of the ankle, peroneus quartus muscle, is located in the lateral leg compartment. In literature there is ambiguous nomenclature of this muscle because of its different origin and insertion sides. It is related to many pathologic conditions in the lateral ankle compartment but also it can be used as a tendon graft for reconstructive procedures.

Material and method

We dissected 115 cadaver legs and investigated prevalence of peroneus quartus. We also present 2 year result of a patient who had torn superior peroneal retinaculum reconstructed with peroneus quartus tendon.

Results

The peroneus quartus muscle, with a number of different attachments, was present in 5.2 % (6/115) of the legs. It most commonly arose from the peroneus brevis muscle and inserted into the retrotrochlear eminence of the calcaneus. Associated pathologies are longitudinal degeneration and tear in the tendon of peroneus brevis. There is no any association between the prevalence of peroneus quartus and the height of retrotrochlear eminence or presence of peroneal tubercule (p > 0.05). But there is strong relationship between peroneus brevis degeneration and peroneus quartus existence (p: 0.03). We also defined a new type of peroneus quartus with a bifurcated insertion around the peroneus brevis. In literature our case report is unique because we present a patient who has torn superior peroneal retinaculum which is reconstructed with peroneus quartus tendon with 2 year follow up.

Conclusion

Peroneus quartus may lead to some pathologic conditions (pain, snapping, tear, synovitis, etc.) in the lateral ankle compartment but it may be used to reconstruct some pathologic conditions. Orthopaedics, anatomists and radiologists should be aware of this accessory tendon structure because of its clinical importance.
