Supraorbital Foramen

Currently, interventions with anesthetic substances have been an alternative for headache treatment. There are some regions that are targeted for the application of anesthetics, such as the upper margin of the orbit, where two critical nerves, supratrochlear and supraorbital, pass. The objective of this study is to present some anatomical features characteristic of the superior orbital border and passage of the supraorbital nerve through a foramen or more often notch. Dry skulls from male and female individuals were used, measures were taken to compare the distance between the foramen and the median line of the skull. The length was measured and compared between the sexes, obtaining the following results in men (2.27 ± 0.29 cm) and women (2.18 ± 0.41 cm). The collected data are of extreme importance to understand the anatomy of the region and intervention in procedures of infiltrations and treatment of headache.

The 12 species previously placed in Tortopus together with 3 species newly described here, are revised and included in a phylogenetic analysis. Based on synapomorphic characters on the nymphs and adults of both sexes, Tortopus is restricted to T. igaranus Needham & Murphy, T. circumfluus Ulmer, T. harrisi Traver, T. zottai (Navás), T. bellus Lugo-Ortiz & McCafferty, and T. arenales sp. nov., and the genus is defined by: female parastyli receptors with long furrows anterior to sockets; penes entirely flattened; male ninth abdominal sternum almost separated in two portions by a median notch; mesosternum with furcasternal protuberances contiguous only on basal corner; and nymphs with two subapical tubercles on mandibular tusks. Tortopsis is newly described for T. bruchianus (Navás), T. limoncocha sp. nov., T. obscuripennis (Domínguez), T. parishi (Banks), T. primus (McDunnough), T. puella (Pictet), T. sarae (Domínguez), T. spatula sp. nov., and T. unguiculatus (Ulmer). Tortopsis is characterized by: R sector of female fore wing without additional veins between R 2 and IR; female parastyli receptors C or V-shaped, with sockets opening towards median line; male gonopore associated with a claw-like structure; penes separated from the base; parastyli more than 5 times length of pedestals; parastyli curved in lateral view; nymphs with a single subapical tubercle on mandibular tusks. The study of available type material permitted inclusion of comparative diagnoses, with figures and redescriptions as needed. The male imago of the type species of Tortopus (T. igaranus Needham & Murphy) is described for the first time, as are the female adults of Tortopus bellus Lugo-Ortiz & McCafferty and T. harrisi Traver. Three new Neotropical species based on male and female adults are described: Tortopus arenales and Tortopsis limoncocha from Ecuador, and Tortopsis spatula from Colombia. Keys to separate the adults and nymphs of the genera of Polymitarcyidae, and for male and female adults of all the species of Tortopus and Tortopsis are presented, as well as line drawings, pictures and SEM photographs of important structures.

PURPOSE: To investigate the facial symmetry of rats submitted to experimental mandibular condyle fracture and with protein undernutrition (8% of protein) by means of cephalometric measurements. METHODS: Forty-five adult Wistar rats were distributed in three groups: fracture group, submitted to condylar fracture with no changes in diet; undernourished fracture group, submitted to hypoproteic diet and condylar fracture; undernourished group, kept until the end of experiment, without condylar fracture. Displaced fractures of the right condyle were induced under general anesthesia. The specimens were submitted to axial radiographic incidence, and cephalometric mensurations were made using a computer system. The values obtained were subjected to statistical analyses among the groups and between the sides in each group. RESULTS: There was significative decrease of the values of serum proteins and albumin in the undernourished fracture group. There was deviation of the median line of the mandible relative to the median line of the maxilla, significative to undernutrition fracture group, as well as asymmetry of the maxilla and mandible, in special in the final period of experiment. CONCLUSION: The mandibular condyle fracture in rats with proteic undernutrition induced an asymmetry of the mandible, also leading to consequences in the maxilla.

After citing the descriptions by Cuvier, Kaup, Bronn, and De Blainville of the Eustachian tubes and the foramina in the base of the cranium of the recent and extinct Crocodiles, the author gives an account of the nerves, arteries, veins and air-tubes that traverse these different foramina, and thus determines the true position of the ca­rotid foramina and posterior nostrils in the Teleosauri and other fossil Crocodilia which had been a matter of controversy amongst the authors cited. In the course of these researches the author dis­covered a distinct system of Eustachian canals superadded to the or­dinary lateral Eustachian tubes, which he describes as follows:— “From each tympanic cavity two passages are continued down­wards, one expands and unites with its fellow from the opposite side to form a median canal which passes from the basisphenoid to the suture between that and the basioccipital, where it terminates in the median canal continued to the orifice described by M. De Blainville as the posterior nostril. The second passage leads from the floor of the tympanic cavity to a short canal which bends towards its fellow, expands into a sinus and divides: one branch descends and termi­nates in the small lateral foramen at the lower end of the suture be­ tween the basioccipital and the basisphenoid: the other branch continues the course inwards and downwards until it meets its fellow at the median line of the basioccipital, and it forms the posterior primary division of the common median canal: this soon joins the anterior division, and the common canal terminates at the median opening below. Membranous tubes are continued from the three osseous ones, and converge to terminate finally in the single Eusta­chian orifice on the soft palate behind the posterior nostril. The mucous membrane of the palate lines the various osseous canals above described, and is continued by them into the lining membrane of the tympanum.”

Abstract The level selection of frequency band division structure relies on previous information in most gram approaches that capture the optimal demodulation frequency band (ODFB). When an improper level is specified in these approaches, the fault characteristic information contained in the produced ODFB may be insufficient. This research proposes a unique approach termed median line-gram (MELgram) to tackle the level selection problem. To divide the frequency domain signal into a series of demodulation frequency bands, a spectrum median line segmentation model based on Akima interpolation is first created. The level and boundary of the segmentation model can be adaptively identified by this means. Second, the acquired frequency bands are quantized using the negative entropy index, and the ODFB is defined as the frequency band with the largest value. Third, the envelope spectrum is used to determine the ODFB characteristic frequency to pinpoint the bearing fault location. Finally, both simulation and experimental signal analysis are used to demonstrate the efficiency of the suggested method. Furthermore, the suggested method extracts more defect feature information from the ODFB than existing methods.

Line Of Therapy

Thirty pretreated patients with progressive and measurable solid tumors (24/30 patients) or myeloproliferative diseases (6/30 patients) were given mitoxantrone at the dose of 5 mg/m2/day in 250 ml normal saline over 30 minutes infusion for 3 consecutive days every 3 weeks. A total of 104 cycles were administered, median 3 for each patient. 39/104 cycles were delayed for a median of 9 days (from 2 to 59 days) because of myelodepression grade I to III (median I); no infection or bleeding was observed. Grade I to II alopecia was recorded in 16 patients. Chronic cardiac toxicity was observed in one patient previously treated with adriamycin. Mitoxantrone at the studied dose schedule in heavily pretreated subjects was well tolerated every 3 to 4 weeks. In 25/30 patients evaluable for response, one patient had a PR, another had 25% reduction (both patients previously treated) and eleven patients obtained disease stability. This effectiveness, 1 PR, 1 MR, 11 disease stability, is not negligible when it is considered that mitoxantrone was the seventh median line of therapy and the fifth median antiblastic drug.
