A novel technique for transportation osteogenesis in a severe maxillary post traumatic defect.

Bone maxillary post traumatic defects create significant aesthetic and functional handicaps remaining a critical challenge for surgical reconstruction, among all the alternatives that exist, transportation osteogenesis remains a body ally for having satisfactory results. We present a case of 26 mm of maxillary reconstruction with bifocal transportation osteogenesis using a novel technique, with a custom-made device. At the end of the consolidation period, the patient had clinical formation of new tissue corroborated radiographically. We achieve an adequate dentoalveolar arch, upper lip vestibule, gingiva and palatal fibromucosa similar to the adjacent tissue, improvement of facial contour, labial projection, nostril floors and masticatory function.

[The clinico-epidemiological characteristics of cholera patients in Mexico City]. / Características clínico-epidemiológicas de pacientes con cólera en la ciudad de México.

OBJECTIVE: To compare the clinical and epidemiological characteristics of cholera patients and patients with diarrhea of different etiology (controls), treated at Mexican Institute of Social Security medical units in northeast Mexico City, from 1995 to 1998. MATERIAL AND METHODS: Cross-sectional analytical study design. Data were collected using the official form "Immediate Notification of Cholera Cases" that each medical unit reports to the Coordination of Community Health. Statistical analysis consisted of comparisons of means and proportions between both groups. RESULTS: In 4,952 notifications, there were 588 cholera cases and 4,364 controls. The age range of cases was 39 to 51 years and 54% were females. During 1995 and 1997 (years with higher proportion of cases) patients with cholera had a greater frequency of watery evacuations than controls (97% vs. 73%), "rice water" appearance (31% vs. 13%), vomiting (72% vs. 63%), muscular spasms (49% vs. 26%), dehydration (83% vs. 71%), hypovolemic shock (10% vs. 1%) and death (0.85% vs. 0.25%). These differences were statistically significant. CONCLUSIONS: Cholera presents a biannual cyclic behavior; greater frequencies are associated with greater severity and complications. It is necessary to increase epidemiologic surveillance and medical efforts for opportune diagnosis and treatment.
