Treatment of hemorrhagic lymphatic malformation of the tongue with a pulsed-dye laser

Hemorrhagic lymphatic malformation (formerly called hemolymphangioma) of the tongue is an uncommon malformation that may pose both functional and cosmetic problems for the patient. The challenge has been to find a conservative treatment with low morbidity and better results than those achieved with surgical excision, which has been the mainstay of therapy. We report a case of successful treatment of a hemorrhagic lymphatic malformation of the tongue with a variable-pulse 595-nm pulsed-dye laser (Vbeam; Candela Corp, Wayland, Mass). In this patient, pulsed-dye laser treatment of the hemorrhagic lymphatic malformation achieved satisfactory functional and cosmetic outcomes. Its use in superficial vascular lesions of the mucosa should be considered.     

CT findings in patients with chronic thrombembolic pulmonary hypertension

Chronic thromboembolic pulmonary hypertension (CTEPH) is thought to be a rare complication of pulmonary embolism. However, it was recently demonstrated that CTEPH is more common than previously thought after pulmonary embolism. Without treatment, CTEPH is associated with a very high mortality rate. Making the correct diagnosis early is essential, because there is a potential curative treatment in the form of pulmonary thromboendarterectomy (PTE). Because of the unspecific clinical symptoms of CTEPH, the different imaging modalities play a crucial role in diagnosis making. Since the introduction of the multidetector CT technology, CT has become an important part in the diagnostic work up of pulmonary embolism and CTEPH and is often used as a first-line diagnostic tool. CT is not only a reliable tool for the diagnosis of CTEPH, but also is helpful in estimating the operability of these patients. PTE is still associated with a mortality rate of about 10%. Particularly an insufficient decrease of the pulmonary vascular resistance after PTE leads to a very high mortality rate. Therefore, it is crucial to correlate the degree of the surgical accessible obstruction of the pulmonary vasculature with the degree of pulmonary hypertension in deciding for or against PTE. The aim of this review is to describe the CT findings in patients with CTEPH and their use in differentiating CTEPH from other diseases like acute pulmonary embolism and primary pulmonary hypertension. Moreover, the correlation of different CT imaging features with surgical success after PTE will be discussed.     

Comparison of two therapeutic protocols in patients with antiphospholipid antibodies and recurrent miscarriages

AIM: To compare the effects of two therapeutic protocols for the patients with recurrent miscarriages associated with the presence of antiphospholipid (anticardiolipin) antibodies. METHODS: A prospective observational study included 20 patients with antiphospholipid antibodies in the first group who received low-molecular heparin and aspirin. The second group of 20 patients, in addition to this therapy, received immunotherapy (intravenous immunoglobulin). Aspirin was administered at the time of a positive pregnancy test, and low-molecular heparin not before the fetal heart activity registration by ultrasound. Intravenous immunoglobulin was given prior to the conception or at the beginning of the pregnancy. We compared these groups according to the pregnancy outcomes and the occurrence of complications during pregnancy, using standard statistical tests. RESULTS: The rate of positive gestational outcome in the patients treated with aspirin and low-molecular heparin was 85% (17/20), and in the second group it was 90% (18/20). There was no significant difference in pregnancy outcomes between these groups (p > 0.05), except for the occurence of preeclampsia and thrombocytopenia, which were recorded only in the aspirin and low-molecular heparin group, but with no statistical significance (p > 0.05) compared to the second group, which received immunoglobulin additionally. CONCLUSION: There was no significant difference (p > 0.05) in pregnancy outcomes between the two studied therapeutic protocols, but the therapy with aspirin and low-molecular heparin was cheaper and easier to apply than the therapy with immunoglobulins. The results of our study confirmed that the final pathogenic mechanisms in recurrent fetal miscarriages were inflammation and thrombosis of the uteroplacental blood vessels.     

Acute leg compartment syndrome after exertion

A case of a 22-year old soldier, with a history of pain in the leg during heavy exercise, which desisted at rest, was presented. One day before admission, the patient had felt an extreme exertion-induced pain in his right leg which had not lessenned at rest. At the same time, the patient noticed persistent severe leg edema. On physical examination, the intracompartmental pressure was 62 mmHg (> 30 mmHg). The patient was urgently operated on, and fasciotomy according to Mubarak was used. At second surgery, the debridement of the muscles of the posterior group of the leg, and the evacuation of hemathoma from the anterior and lateral group of the right leg muscles were perfomed. Postoperative recovery was uneventful. Fasciotomy wounds were closed within 14 days of the surgery. The complete physical treatment was done. Follow-up examinations 1, 3, and 6 months afterwards were satisfactory. The soldier completed his compulsory military service without any sequelae. Laboratory results were normal. Overlooked, unrecognized or surgically untreated compartment syndrome can cause severe damage, including even the loss of the extremity.     

Effects of circumferential rigid wrist orthoses in rehabilitation of patients with radius fracture at typical site

BACKGROUND: The use of orthoses is a questionable rehabilitation method for patients with the distal radius fracture at typical site. The aim of this study was to compare the effects of the rehabilitation on patients with radius fracture at the typical site, who wore circumferential static wrist orthoses, with those who did not wear them. METHODS: Thirty patients were divided into 3 equal groups, 2 experimental groups, and 1 control group. The patients in the experimental groups were given the rehabilitation program of wearing serially manufactured (off-the-shelf), as well as custom-fit orthoses. Those in the control group did not wear wrist orthoses. Evaluation parameters were pain, edema, the range of the wrist motion, the quality of cylindrical, spherical, and pinch-spherical grasp, the strength of pinch and hand grasp, and patient's assessment of the effects of rehabilitation. RESULTS: No significant difference in the effects of rehabilitation on the patients in experimental groups as opposed to control group was found. Patients in the first experimental group, and in control group were more satisfied with the effects of rehabilitation, as opposed to the patients in the second experimental group (p<0.05). CONCLUSION: The effects of circumferential static wrist orthoses in the rehabilitation of patients with distal radius fracture at the typical site were not clinically significant. There was no significant difference between the custom and off-the-shelf orthoses.     

Role of extracellular phospholipases and mononuclear phagocytes in dissemination of cryptococcosis in a murine model

Secreted phospholipase B (PLB) activity promotes the survival and replication of Cryptococcus neoformans in macrophages in vitro. We therefore investigated the role of mononuclear phagocytes and cryptococcal PLB in the dissemination of infection in a mouse model, using C. neoformans var. grubii wild-type strain H99, a PLB1 deletion mutant (Delta plb1), and a reconstituted strain (Delta plb1(rec)). PLB facilitated the entry of endotracheally administered cryptococci into lung IM. PLB was also required for lymphatic spread from the lung to regional lymph nodes and for entry into the blood. Langhans-type giant cells containing budding cryptococci were seen free in the lymphatic sinuses of hilar nodes of H99- and Delta plb1(rec)-infected mice, suggesting that they may have a role in the dissemination of cryptococcal infection. The transfer of infected lung macrophages to recipient mice by tail vein injections demonstrated that these cells can facilitate hematogenous dissemination of cryptococci to the brain, independent of cryptococcal PLB secretion. PLB activities of cryptococci isolated from lung macrophages or infected brains were not persistently increased. We conclude that mononuclear phagocytes are a vehicle for cryptococcal dissemination and that PLB activity is necessary for the initiation of interstitial pulmonary infections and for dissemination from the lung via the lymphatics and blood. PLB is not, however, essential for the establishment of neurological infections when cryptococci are presented within, or after passage through, mononuclear phagocytes.     

Carbamazepine for acute psychosis with EEG abnormalities

AIM: To investigate the efficacy of carbamazepine as adjuvant drug therapy in acute paranoid psychosis with associated EEG abnormalities, compared to sole antipsychotic treatment. METHODS: Eleven medication-naive patients, diagnosed with acute paranoid psychosis with associated EEG abnormalities, were divided into two treatment groups: sole fluphenazine group, with flexible dosing of 5-10 mg/day (n=6), and carbamazepine group (n=5) with the addition of carbamazepine (600 mg/day) to fluphenazine treatment. Clinical Global Impression (CGI), Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Negative Symptoms (SANS), and EEG were assessed on the baseline and after 6 weeks of treatment. Paired and two-tailed t-tests were used for statistical significance. RESULTS: All the patients showed significant improvement of mental state after 6 weeks of treatment with no significant differences in CGI, BPRS, and total SANS scores in relation to the therapy with carbamazepine. Nevertheless, after 6 weeks of the treatment, EEG findings were significantly better in carbamazepine group, in relation to the findings from the onset of the treatment, as well as in comparison to sole fluphenazine group. CONCLUSION: Although carbamazepine stabilized abnormal brain electrical activities it seemed that the associated EEG abnormalities were not significant for acute psychosis observed. These preliminary results suggested that there was no convincing evidence that carbamazepine was efficient as the augmentation of antipsychotic treatment for patients with both acute paranoid psychosis and EEG abnormalities.
