Description:
Small bowel obstruction is a common clinical problem presenting with abdominal distention, colicky pain, absolute constipation and bilious vomiting. There are numerous causes, most commonly attributed to an incarcerated hernia, adhesions or obstructing mass secondary to malignancy. Here we present an unusual cause of a small bowel obstruction secondary to an incarcerated incisional hernia in association with an acute organoaxial gastric volvulus. and N. R. Kosai, H. S.

Description:
The purpose of this study was to test the hypothesis that more recently developed rubber dam systems (OptraDam ® Plus and OptiDam™) are faster and easier to handle, and that the quality of isolation is not decreased. The rubber dam systems were applied in standard conditions on a dental simulator in several model clinical situations. The time of preparation, application and removal were measured and the quality of isolation was evaluated. The median time of rubber dam placement was 51 s (Q1 = 38 s; Q3 = 79 s). The shortest median time of application was with OptiDam™ (42 s), followed by a conventional rubber dam (53 s), and finally the longest was with OptraDam® Plus (58 s). The median volume of fluid remaining in the isolated space after 5 minutes was 9.5 mL (Q1 = 8 mL; Q3 = 10 mL). The largest median volume of remaining water was with OptiDam™ (10 mL), followed by a conventional rubber dam (9.5 mL) and the least with OptraDam® Plus (8.5 mL). The afore-stated hypothesis about the advantages of modern rubber dam isolation systems was accepted for OptiDam™, but rejected for OptraDam® Plus. The results could contribute to decision-making concerning the choice of rubber dam system. and Martin Kapitán, Zdeňka Šustová, Romana Ivančaková, Jakub Suchánek

Description:
Short-winged (brachypterous) and long-winged (macropterous) adult females of Pyrrhocoris apterus (L.) originating from a Mediterranean population (Israel) were analyzed for their adipokinetic responses. The adipokinetic response, expressed as an increase of haemolymph lipids after injection of adipokinetic hormone from Locusta migratoria (Lom-AKH-I), was assessed in relation to age and dose of the hormone. We demonstrate in this study that the adipokinetic responses induced by bug's corpora cardiaca extract and Lom-AKH-I were dose-dependent for both brachypterous and macropterous females. Significant differences between the morphs were recorded for doses >= 0.25 corpora cardiaca equivalent (P < 0.01) and doses >= 0.25 pmol Lom-AKH-I (P < 0.05). The haemolymph lipid elevations induced in both morphs by 2 pmols Lom-AKH-I are comparable with that induced by crude extract of one pair of the bug's own corpora cardiaca. The age-dependent test showed much higher adipokinetic responses (P < 0.01) in macropterous females (>= 5 days old) than in the brachypterous females of the same age, when treated with 2 pmols Lom-AKH-I. Starting from day 7, the concentration of haemolymph lipids was also considerably higher (2.5-5 times) in macropterous females than in the brachypterous ones. The obtained data indicate that difference in mobilization of lipids between brachypterous and macropterous females is a geographically independent feature and represents a true wing morph characteristic of P. apterus., Dalibor Kodrík, Radomír Socha, and Lit

Description:
BACKGROUND: Radio frequency (RF) and chemical peels have been used for nonablative skin rejuvenation. Both of these cause collagen remodeling in the dermis and neo-collagen formation resulting in facial rejuvenation. There is limited literature on the evaluation of collagen remodeling by objective methods. OBJECTIVE: To compare the benefits of monopolar radiofrequency and glycolic acid peels in facial rejuvenation with regards to histopathology and Ultrabiomicroscopic sonography (UBM). METHODOLOGY: In this study, forty patients with mild to moderate photoaging received four treatments with 3 weeks interval of monopolar radiofrequency on one side of face and glycolic acid peels in increasing concentrations (NeostrataR) on the other side. Pre and post treatment, 2 mm biopsies were taken from both preauricular areas and Ultrasonography using a 35 MHz probe was done from outer canthus of eye and nasolabial folds from both sides of face. A blinded assessment was done to measure the increase in the grenz zone and dermal thickness. RESULTS: In 35/40 patients there was a significant increase in the grenz zone on histopathology and decrease in subepidermal low-echogenic band (SLEB) on UBM of the nasolabial folds on both sides of the face (p < 0.05). CONCLUSION: Radiofrequency and chemical peels showed equal efficacy in the treatment of facial rejuvenation. and D. V. Wakade, C. S. Nayak, K. D. Bhatt

Description:
Hereditární hemoragická teleangiektázie neboli morbus Rendu‑Osler‑Weber je fibrovaskulární dysplazie s autozomálně dominantní dědičností charakteristická přítomností teleangiektázií a arteriovenózních malformací kůže, sliznic a vnitřních orgánů. Plicní arteriovenózní malformace jako zdroj septických embolů mohou zapříčinit vznik mozkového abscesu, který tak bývá prvním a často jediným projevem heriditární hemoragické teleangiektázie. V práci jsou prezentovány tři kazuistiky pa­cientů trpících touto chorobou, kde prvním a závažným příznakem byl vzniklý mozkový absces. Protože se jedná o relativně vzácné onemocnění, nebývá vždy zvažováno v rámci diferenciální dia­gnostiky a tím pádem ani dia­gnostikováno. U každého pa­cienta s mozkovým abscesem je nezbytné na toto onemocnění pomýšlet a v případě podezření je nutné jej řádně vyšetřit. Při verifikované plicní arteriovenózní malformaci je třeba ji ošetřit a zabránit tak vzniku recidivujících mozkových abscesů. Péče o tyto pa­cienty je komplexní a multioborová., Hereditary hemorrhagic telangiectasia or Rendu‑Osler‑Weber disease is an autosomal‑dominant disorder that results in fibrovascular dysplasia and is characterized by telangiectases and arteriovenous malformation of the skin, mucosa and viscera. Pulmonary arteriovenous malformations as a source of septic emboli may give rise to brain abscess that so often is the first and only clinical manifestation of hereditary hemorrhagic telangiectasia. Three cases of patients suffering from this disease with brain abscess as the first and serious symp­tom are presented. Since this is a relatively rare disease, it is not always considered in the differential dia­gnosis and thus not dia­gnosed. This disease has to be considered in patients with brain abscess and, in case of a suspicion, it must be properly examined. When pulmonary arteriovenous malformation is verified, it has to be treated in order to prevent recurrent brain abscesses. Care of these patients should be comprehensive and multidisciplinary. Key words: hereditary hemorrhagic telangiectasia – Rendu-Osler-Weber disease – brain abscess – arteriovenous malformation – epistaxis – endoglin The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manu­script met the ICMJE “uniform requirements” for biomedical papers., and G. Hanoun, V. Vybíhal, M. Sova, J. Boudný, T. Svoboda, M. Smrčka

Language:

Description:
In cockroaches and certain other insects the concentration of trehalose in the hemolymph is increased by hypertrehalosemic hormone (HTH), a neuropeptide originating in the corpus cardiacum. A vital step in the action of HTH to promote conversion of glycogen stored in the fat body to trehalose is the activation of phosphorylase. The means by which HTH activates phosphorylase, with particular emphasis on its role in the regulation of intracellular calcium, is discussed. Additional information supporting the view that HTH stimulated synthesis of trehalose, and possibly its release from the trophocyte, is regulated by fatty acids and eicosanoids is presented., John E.

Description:
Introduction: Obstruction of the appendiceal lumen is the primary cause of appendicitis. The most common causes of luminal obstruction are fecaliths and lymphoid follicle hyperplasia. Additionally, bacterial infections or enteric and systemic viral diseases can cause a reaction of the lymphoid follicle. Case presentation: An 11-year-old boy with active phase of chickenpox presented on our Pediatric surgery emergency department under the impression of acute appendicitis. An appendectomy was performed on the same day. An inflamed and edematous retrocecal appendix was removed during surgery. Histological investigation of the appendix revealed transmural acute inflammation, with diffuse proliferation of inflammatory cells, with characteristic intranuclear inclusion surrounded by a clear halo. The PCR analysis of peripheral blood and appendix tissue specimen revealed positive VZV DNA. Conclusion: We have shown that varicella-zoster virus infection of the appendix is associated with acute appendicitis and possibly also with severity of the disease., Zenon Pogorelić, Mihovil Biočić, Ivo Jurić, Klaudio Pjer Milunović, Ivana Mrklić, and Literatura 11
