BACKGROUND: The philtrum and the Cupid’s bow are the most prominent features of the upper lip and are crucial for normal appearance. Unfortunately, projection of the philtral column is a common deficiency of the repaired cleft lip. Although a multitude of methods for constructing the philtral dimple and ridge have been described, no single procedure has achieved complete satisfactory results. The authors describe their technique for construction of the philtral column using palmaris longus tendon. METHODS: Between 1998 and 2009, a retrospective study was performed for identifying patients with depression of the philtral scar following cleft lip repair. Pre- and postoperative photographs were taken with at least 6 months follow-up. Postoperative patient satisfaction and occurrence of complications are reported. RESULTS: In all, 17 patients who developed depression of the philtral ridge following cleft lip repair underwent philtral reconstruction utilizing palmaris longus tendon grafts by the senior author (H.K.K.). At the time of surgery, average age for 11 females and 6 males was 18.5 years. The follow-up period ranged from 6 to 126 months, with an average of 42.3 months. In the early postoperative period, 2 complications in the form of graft exposure occurred. However, both cases were successfully managed with preservation of the graft. All patients were satisfied with their long-term results, and none required further surgery. CONCLUSIONS: The use of palmaris longus tendon graft is an effective, reproducible, and safe method by which to construct the philtral column in the secondary cleft lip deformity.

We examined the role of nitrergic, glutamatergic and gamma-aminobutyric acid (GABA)-ergic systems in the mechanism(s) underlying lithium induced acute toxicity. With this aim, lithium (18 mEq/kg, i.p.) intoxicated rats were observed for 3 hr recording their clinical signs and death. Lithium exposure at the dose used produced central nervous system (CNS) depression. Pre-treatment of N(w)-nitro-L-arginine methyl ester (L-NAME) a nonselective nitric oxide synthase inhibitor (10 mg/kg, i.p.), 7-nitroindazole (7-NI) a selective neuronal nitric oxide synthase inhibitor (25 mg/kg, i.p.), nitric oxide precursor L-arginine (1,000 mg/kg, i.p.) and MK-801 a noncompetitive antagonist of N-methyl-D-aspartic acid class of glutamate receptors (0.5 mg/kg, i.p.) all increased CNS depression and mortality in lithium group however, no change was seen in GABA receptor agonist GABA (1,000 mg/kg, i.p.) or D-arginine (1,000 mg/kg, i.p.) a biologically inactive enantiomer of L-arginine pre-treated rats. Glutamic acid decarboxylase (GAD) enzyme activity was measured in hippocampus, cerebral cortex and cerebellum of the different groups of animals. GAD enzyme activity reduced in cerebral cortex but not altered in hippocampus or cerebellum by lithium as compared to the control (saline) group. We conclude that an interaction with nitrergic and glutamatergic systems may have a role in the acute toxicity of lithium in rats.The inhibition of glutamate metabolism may arise from this interaction and the involvement of GABA-ergic system should be further investigated in this toxicity.

Background: The Living with COPD (LCOPD), COPD and Asthma Fatigue Scale (CAFS), and COPD and Asthma Sleep Impact Scale (CASIS) are instruments developed to assess the overall impact of chronic obstructive pulmonary disease (COPD) on daily life, fatigue, and sleep impairment, respectively. Objectives: To assess the usefulness of these instruments and to identify factors associated with the concepts they measure. Method: The questionnaires were administered to patients with moderate to severe COPD. Descriptive analyses of sociodemographic and clinical data were performed, and bivariate and multivariate analyses were used to identify factors associated with the overall impact of COPD on patients’ lives, fatigue, and sleep impairment. Results: A total of 408 patients was included (mostly males, 91.2%), with an average age of 68 years (SD = 9.3). Statistically significant differences were observed in the scores of the three questionnaires with regard to level of education, presence of chronic cough or expectoration, level of dyspnea, number of exacerbations, physical activity level, presence of depression and anxiety, and number of treatments indicated for COPD. The LCOPD and CAFS questionnaires also discriminated between different levels of airflow obstruction and, in the case of CAFS, age and gender. Linear regression showed that level of dyspnea, physical activity, and presence of anxiety were significantly related to the LCOPD, CAFS and CASIS scores. The presence of depression was significant in the LCOPD and CAFS questionnaires and chronic cough was significant in the CAFS questionnaire. Conclusions: The LCOPD, CAFS, and CASIS instruments are valid and useful in understanding the overall impact of COPD on daily life, fatigue, and sleep impairment in patients with moderate to severe COPD.
