Epidemiological and clinical characteristics of pediatric lower extremity amputation and functional rehabilitation / 中国康复理论与实践

ObjectiveTo analyze the epidemiological and clinical characteristics of children's lower extremity amputation and amputation rehabilitation, and to explain the causes of children's amputation and the complications after amputation. MethodsFrom January, 2016 to March, 2021, 51 amputation related children were retrospectively analyzed. The correlation between the cause of amputation and complications post amputation were analyzed. ResultsTraumatic amputations accounted for 58.82%, and the main cause was traffic accidents (70%). Amputations caused by diseases accounted for 41.18%, and the main cause was congenital limb deformities (80.95%). Traumatic amputation was more likely to have stump complications than expected (P < 0.05). The possibility of stump complications after disease-specific amputation was lower than expected (P < 0.05). ConclusionTraffic trauma is the main cause of amputation in children and is characterized clinically by a high incidence of unsatisfactory stumps, mainly due to soft tissue abnormalities, and most cases require stump revision to improve the poor residuals for prosthetic restoration of ambulation. Congenital pseudarthrosis of the tibia is the main cause of disease-specific amputation, and the outcome of amputation often cannot be definitely avoided even after long-term limb preservation treatment.

Comparison of Unsatisfactory Samples from Conventional Smear versus Liquid-Based Cytology in Uterine Cervical Cancer Screening Test

BACKGROUND: Cervical cytology for uterine cervical cancer screening has transitioned from conventional smear (CS) to liquid-based cytology (LBC), which has many advantages. The aim of this study was to compare the proportion of unsatisfactory specimens from CS versus LBC at multiple institutions including general hospitals and commercial laboratories. METHODS: Each participating institution provided a minimum of 500 Papanicolaou (Pap) test results for analysis. Pap tests were classified according to the participating institution (commercial laboratory or general hospital) and the processing method (CS, ThinPrep, SurePath, or CellPrep). The causes of unsatisfactory results were classified as technical problems, scant cellularity, or complete obscuring factors. RESULTS: A total of 38,956 Pap test results from eight general hospitals and three commercial laboratories were analyzed. The mean unsatisfactory rate of LBC was significantly lower than that of CS (1.26% and 3.31%, p = .018). In the LBC method, samples from general hospitals had lower unsatisfactory rates than those from commercial laboratories (0.65% vs 2.89%, p = .006). The reasons for unsatisfactory results were heterogeneous in CS. On the other hand, 66.2% of unsatisfactory results in LBC were due to the scant cellularity. CONCLUSIONS: Unsatisfactory rate of cervical cancer screening test results varies according to the institution and the processing method. LBC has a significantly lower unsatisfactory rate than CS.

Relationship between unsatisfactory release of LVIS stent and vascular tortuosity in the cavernous segment of internal carotid artery / 中国脑血管病杂志

Objective To investigate the effect of vascular tortuosity and bending radius on the new type knitting stents (LVIS stent ) releasing on the cavernous sinus segment of internal carotid artery. Methods From December 2015 to January 2016,31 consecutive patients with wide-neckedaneurysm treated with LVIS stents and the proximal end of the stent released in the cavernous segment at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were enrolled. According to whether the stents completely adhered to the walls or not after the first release,they were divided into two groups:a satisfactorily release group (n =23 )or an unsatisfactorily release group (n =8 ). The differences of vascular tortuosity and bending radius of the 2 groups were compared.Results Thevascular tortuosities of the satisfactorily release group and the unsatisfactorily release group were 118° ± 23° and 147° ± 19° respectively. There was significant difference (P=0. 028). The vascular bending radii were 3. 4 ± 0. 7 mm and 2. 8 ± 0. 7 mm respectively. There was significant difference (P=0. 042). The mean vascular tortuosity was larger and the mean vascular bending radius was smaller in the unsatisfactorily release group. Conclusions The greater the vascular tortuosity,the smaller the vascular bending radius may be connected with the unsatisfactorily release in the LVIS stent. The evaluation of vascular tortuosity is conductive to the guidance of the stent release technique before stent implantation.

Citologías cervico-vaginales no satisfactorias en el hospital “Manuel Noriega Trigo” de Maracaibo / Unsatisfactory cervico-pap tests at the hospital

Objetivo: Determinar el porcentaje de citologías cervico-vaginales no satisfactorias en el Hospital “Manuel Noriega Trigo”. Métodos: Se revisaron retrospectivamente las citologías cervico-vaginales estudiadas en el Servicio de Anatomía-Patológica del período comprendido entre noviembre 2008 a diciembre de 2009. Resultados: Se revisaron 1 566 citologías cervico-vaginales reportándose 126 como insatisfactorias (8.%). Las causas más frecuente de citologías cervico-vaginales no satisfactoria fue la falta de identificación del paciente (n=53, 36,8 %), la abundancia de leucocitos (n=31, 21,5 %) y la presencia de abundantes hematíes (n=26, 18,1 %). Diez y siete citologías cervico-vaginales (14,3 %) presentaron varias causas para ser catalogadas como insatisfactorias. Ochenta (63,5 %) de 126 citologías cervico-vaginales reportadas insatisfactorias fueron reportadas como negativas para malignidad. Cuarenta (31,7 %) de las (126 citologías cervico-vaginales) insatisfactorias fueron consideradas como imposibles de ser analizadas o estudiadas por el citotecnólogo o patólogo, representaron el 2,6 % del total de las estudiadas. En 33 citologías cervico-vaginales (2,1 %), no se encontraron células endocervicales. Los centros asistenciales que presentaron un mayor número de citologías cervico-vaginales no satisfactorias fueron el Hospital “Manuel Noriega Trigo” con 63 (50 %), Ambulatorio El Silencio con 31 (24,6 %) y el Ambulatorio El Caujaro con 17 (13,5 %), sin embargo, en proporción, fueron los Ambulatorios El Silencio (31 de 133 citologías cervico-vaginales, 23,3 %) y El Caujaro (17 de 115 citologías cervico-vaginales, 14,8 %) los que tuvieron mayor número de citologías cervico-vaginales insatisfactorias. Conclusiones: El porcentaje de citologías cervico-vaginales insatisfactorias fue aceptable cuando se analizaron las causas propias de la toma, procesamiento y lecturas de las citologías cervico-vaginales. Asimismo, el porcentaje de ausencia de células ...

Objective: To determinate the percentage of unsatisfactory Pap smears at Manuel Noriega Trigo Hospital. Methods: Pap smears studied by the Service of Pathology were reviewed retrospectively between November 2008 and December 2009. Results: One hundred twenty six (8 %) of 1 566 Pap smears were reported unsatisfactory. The most common cause of unsatisfactory vaginal cytology was the lack of patient´s identification (n=53, 36.8 %), obscuring smear inflammation (n=31, 21.5 %) and blood (n=26, 18.1 %). Seventeen Pap smear (14.3 %) had several causes to be considered non satisfactory. Eighty (63.5 %) of 126 Pap smear unsatisfactory were negatives to malignancy. Forty (31.7 %) of 126 Pap smear unsatisfactory could not be analyzed neither the cytotechnogist nor the pathologist; they represented 2.6 % of the 1566 Pap smear. Thirty three Pap smear (2.1 %) did not have endocervical cells. Hospital “Manuel Noriega Trigo” (n=63.50 %), El Silencio (n=31, 24.6 %) and El Caujaro (n=17, 13.5 %) have higher number of unsatisfactory vaginal cytologies, however, proportionally El Silencio (31 of 133 Pap smear, 23.3 %) and El Caujaro (17 of 115 Pap smear, 14.8 %) had higher unsatisfactory Pap smears. Conclusion: The percentage of unsatisfactory Pap smears was acceptable when we analyzed causes such as the technique of collection of the Pap smear, the staining technique, and the study of the slide. The number of endocervical cells was low even though the endocervical collection sample was taken with a cotton swab, maybe because Pap smear were taken by medical doctors.

Survey on Satisfaction of Fifth and Sixth Grade Students from Elementary School Foodservice in Won-ju

This study was done to investigate satisfaction of fifth-grade(n=264) and sixth-grade(n=117) students from school foodservice in five elementary schools in Won-ju. On a scale of 1 to 5, with 1 being very poor and 5 being very good, overall satisfaction from school foodservice was found to be 3.21+/-0.98('so-so~satisfaction'). The highest satisfactory factor was neatness of foodservice staffs(3.79+/-1.00), while the lowest satisfactory factor was the students' overall opinions of school foodservice(3.03+/-1.06). The biggest unsatisfactory factor was found to be 'bland food'. 'Enhancement of taste'(49.08%) caused the most complaints against school foodservice. Soup was identified as the type of food most likely to be left over, and there was some significant difference between fifth-graders and sixth-graders. The reason cited most often for leftovers was unfavorable menus(33.42%). Students were more likely to try foods which were unfamiliar to them and also foods they previously disliked as a result of using school foodservice(28.87%). Also significant, when the meal director was present during the meal service, satisfaction was markedly higher than when the director was not present.

The causes of Unsatisfactory Unaided visual Acuity after Exximer Laser PRK for Myopia

we analyzed data from 102 patients(152 eyes) who underwent photorefractive keratectomy to investigate the postoperative causes of unsatisfactory unaided visual acuity. A VISX 20/20 exicimer laser(VISX, Inc, Santa Clara, DA USA, version 4. 01) was used in all cases by one surgeon(J.W.H). The patients who showed unsatisfactory unaided vision, less than 20/40 uncorrected visual acuity, with minimal follow-up periods of 6 months were included. A decreased unaided visual acuity was detected in 20 eyes(13%). Range of preoperative myopia was -2.50 to -14.00 diopters. Mean postoperative uncorrected visual acuity(geometric mean)was 0.33+/-0.12 and mean corrected visual acuity was 0.83 +/-0.25. Multiple factors contributed to unsatisfactory unaided vision; myopic regression in 8 eyes, irregular astigmatism in 4 eyes, overcorrection in 1 eye, severe corneal opacity in 1 eyes(2.6%) and the causes were as follows; irregular astigmatism, decentration combined with central island and severe corneal opacity. In conclusion, refractive results after photorefractive keratectomy were reasonably predictable and stable, but some sight threatening complications occured in a minority eyes. Improved techniques such as centering procedures and improved excimer laser program will be essential to prevent unsatisfactory unaided vision.
