Comparison study of clinical features between persistent hyperplastic primary vitreous and congenital fibrovascular pupillary membrane / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the similarities and differences of the clinical features between persistent hyperplastic primary vitreous(PHPV)and congenital fibrovascular pupillary membrane(CFPM).METHODS: Retrospectively analyze the ocular biometric parameters, clinical features and morphological changes in children with PHPV(PHPV group)and CFPM(CFPM group)who received surgery at the department of ophthalmology, Xijing Hospital from March 2006 to December 2021.RESULTS: The study included 56 cases(61 eyes)of PHPV and 24 cases(25 eyes)of CFPM. There were no differences on the gender and age of onset between PHPV and CFPM, and both of them were mainly unilaterally affected, with the ratio of 91% and 96%. Children with PHPV and cataract combined with other complications and ocular developmental abnormalities. CFPM was mainly presented different degrees of blockage and morphological abnormalities of pupillary area. In unilateral cases of PHPV and CFPM, the anterior chamber depth(ACD)of affected eyes was smaller than that of the fellow eyes, and in subgroups with age of operation ≤24mo, the axial length(AL)of affected eyes was smaller than that of the fellow eyes(P<0.05). The corneal diameter(CD)of the affected eyes in PHPV group was smaller and the intraocular pressure(IOP)was higher than those of the fellow eyes(all P<0.05); while there were no significant differences on CD and IOP between affected eyes and the fellow eyes in CFPM group(P>0.05). The ACD of affected eyes in PHPV group was significantly smaller than that of CFPM group(P<0.05). The fibrovascular membrane in PHPV group was located in the posterior part of the lens and vitreous cavity; while the fibrovascular membrane in CFPM group was located between the iris and the anterior capsule of the lens, rarely involving the lens.CONCLUSION: PHPV and CFPM had the similar clinical features, suggesting that they may belong to the different variants of persistent fetal vasculature(PFV). However, PHPV had a wider range of lesions and more complex conditions.

Management and outcome of colorectal cancer in a resource-limited setting: Ahmadu Bello university teaching hospital, Zaria, Nigeria

Background: Colorectal cancer (CRC) is one of the most common malignancies seen in the Western World. It is increasing in developing countries due to adaptation of the western lifestyle with an incidence of 6% in Nigeria. Treatment options are dependent on the stage of disease at presentation, the performance status of the patient, and increasingly the molecular makeup of the tumor. There is a dearth of data on the treatment options obtainable for the management and outcome of CRC cases in Northwestern, Nigeria. Aim: The study assessed the treatment options and outcome of colorectal cancer patients in a tertiary institution, in Northwestern, Nigeria over a 10-year period. Patients and Methods: Between January 2006 and December 2015, data of one-hundred and twenty-two histologically confirmed colorectal cancer cases seen at the Surgery, Radiotherapy and Oncology Departments, ABUTH Zaria, were retrieved retrospectively from the case files and treatment cards of the patients at the health information unit of the hospital. The stage at disease presentation, treatment received, and outcome were analyzed. Results: Nearly a quarter of the patients fell within the age bracket 31­40 years with the median age being 41 years. While only 41% of the patients had their disease staged, 30.4% of the patients presented with advanced disease (Dukes'C + D). Only 95 cases received a form of surgery or the other. Colostomy however accounted for 28.4%. Eighty-nine of the patients received chemotherapy either as neoadjuvant, adjuvant or with palliative intent. External beam radiotherapy either with radical or palliative intent was received by 60 patients (49.2%). At 1-year follow-up sixty cases had been lost to follow up, and thirty-six cases had defaulted on one form of treatment. Conclusion: The study showed that stage at presentation and the available treatment options in the hospital informed treatment offered to the patients. However, surgery was readily performed due to the pattern of presentation and most patients benefited from just a diverting colostomy. Majority of the patients presented with rectal tumor which required radiotherapy as part of its treatment modality, although this is still a luxury in this part of the world. Chemotherapy is also readily available and often prescribed. Cost and limited facility for biomarker (K-ras) testing restrict the use of targeted therapy. Outcome at 1-year follow-up was poor with whereabouts of nearly half of the patients unknown.

Os resultados demonstraram que no pré-operatório 66,66% dos avaliados apresentavam hipertensão, sendo os gêneros igualmente afetados, 46,66% referiram três ou mais sintomas da comorbidade e escore de saúde mental (40,8 ±16,7) com repercussão relevante. No pós-operatório os parâmetros de normalidade da pressão arterial foram evidenciados em todos os participantes, 57,14% deixaram de necessitar de medicação de controle e houve uma melhora exponencial do escore de saúde mental (81,9 ±21,7). Concluindo que a cirurgia bariátrica compõe um tratamento altamente eficaz para perda ponderal de peso corroborando para normalização da pressão arterial, redução dos sintomas da hipertensão, da necessidade de tratamento medicamentoso para essa finalidade e melhora da saúde geral do indivíduo.

Obesity is a chronic multifactorial disease that triggers several comorbidities, with arterial hypertension being one of the main complications, becoming a risk for the development of cardiovascular diseases and early mortality. Thus, this study aimed at addressing aspects of hypertension related to obesity before and after bariatric surgery. This is a descriptive study, involving individuals of both genders, aged over 18 years submitted to bariatric surgery by the Fobi Capella method with deviation of Roux-en-Y in the city of Toledo, in the state of Paraná, Brazil. For that purpose, 30 participants answered a semi-structured questionnaire investigating blood pressure data. The results showed that in the pre-surgery period, 66.66% of the patients had arterial hypertension, and the genres were equally affected; 46.66% reported three or more symptoms of comorbidity and mental health score (40.8 ± 16.7) with relevant repercussions. In the post-surgery period, normal blood pressure parameters were evident in all participants, 57.14% no longer required control medication and there was an exponential improvement in the mental health score (81.9 ± 21.7), thus concluding that bariatric surgery is a highly effective treatment for weight loss, corroborating blood pressure normalization, reduction of symptoms of hypertension, the need for drug treatment for this purpose and improvement of the individual's general health.

Introducción: el acné conglobata es la forma específica de acné que se caracteriza por la formación de comedones, nódulos, abscesos, quistes, fístulas y cicatrices, las que provocan deformidades. Las lesiones segregan un líquido fétido. No hay tendencia a la resolución espontánea sino que existe un polimorfismo lesional, donde las lesiones alcanzan grandes extensiones con una evolución desfavorable y poca respuesta a los tratamientos. Por su repercusión estética y las cicatrices que quedan como secuela del proceso inflamatorio, esta problemática es de interés científico del dermatólogo y el cirujano estético. Objetivo: organizar las alternativas quirúrgicas disponibles en nuestro contexto para el tratamiento del acné conglobata y sus resultados. Método: se realizó un estudio experimental en un grupo de 30 enfermos de acné conglobata en las provincias de Granma y Holguín del año 2000 al 2014. Los pacientes fueron atendidos en el Hospital Lenin en Holguín, Cuba. El seguimiento a los pacientes permitió definir las lesiones que requerían tratamiento quirúrgico-dermatológico, y un criterio de operabilidad de las lesiones por parte del cirujano estético. Resultados: se obtuvo como resultado que las lesiones con mejor respuesta al tratamiento farmacológico y quirúrgico-farmacológico fueron: comedones, pápulas, pústulas, quistes muy pequeños, menor de 1 cm, y cicatrices atróficas. Se definieron los criterios de operabilidad por la Cirugía Plástica. Se obtuvo una agrupación para los pacientes de acuerdo con la localización, complejidad del cuadro clínico y estado de las lesiones. Se realizó una intervención multidisciplinaria que permitió identificar los casos en estadio precoz y realizar tratamientos quirúrgicos, por el cirujano plástico, con técnicas menos cruentas. Conclusiones: se obtuvieron mejores resultados estéticos, tratamientos menos cruentos y disminución de la estadía hospitalaria y sus complicaciones.

Method: an experimental study from 2000 to 2014 in Holguín and Granma provinces, where thirty patients with conglobata acnes were found. During their evolution we could realize the lesions that required plastic surgery, and the ones for dermatological treatment. Result: the lesions with positive to treatment were comedons, papules inflamed hyperthrophic, a little cystic (lest 1 cm) and atrophic scars. Plastic surgery criteria were determined. The patients with lesions were distributed. The ones with clinical complications and lesions stated. A multidisciplinary intervention to identify the cases early staid and surgery treatment for plastic surgery with lest bloody techniques was accomplished. Conclusion: more aesthetic results, surgery treatment with less aggressive techniques, a short time stay in the hospital and other complications.

Recent progress in research of congenital polydactyly / 中国修复重建外科杂志

Surgery is still the main treatment for congenital polydactyly, and the aim of surgical reconstruction is to obtain a thumb with excellent function and appearance. A systematic assessment of polydactyly is required prior to surgery, including bone stress lines, joint deviation, joint activity and joint instability, size and development of finger and nail. Bone shape, joint incongruency, and abnormal tendon insertions must be corrected completely, in order to obtain good function and to avoide secondary surgery. Bilhault-Cloquet procedure can reconstruct the size of the finger and nails. Fine manipulation can improve the postoperative nail deformity, so that the reconstructed nail reaches a satisfactory aesthetic score.

Objective To compare the efficacy of surgical treatment(ST) and mechanical ventilation treatment(MVT) for flail chest.Methods From March 2013 to May 2017,81 patients with flail chest who underwent ST(28 cases) and MVT(53 cases) were enrolled in ICU.The relevant indicators of efficacy were compared including mechanical ventilation (MV) time,bed rest time,oxygen administration time,catheterization time,antibiotic use time,drug analgesia,drug analgesia patients,proportion of stop/postoperative sputum alone,ICU treatment time,hospital stay,mortality,readmission within two months and long-term pulmonary function after discharge.Results The MV time,bed time,oxygen time,antibiotic use time,ICU treatment time and hospitalization time of MVT were longer than those of ST group,the differences were significant(P ＜ 0.05).MVT had more analgesic times,more analgesic cases,smaller proportion of offline/postoperative sputum along and less hospitalization fees compared with ST group,the differences were significant(P ＜0.05).There was no significant difference in the main indexes of pulmonary function between two groups in 3 months after discharge.Conclusion ST and MVT respectively has advantages and disadvantages for flail chest.There is no significant difference in long-term pulmonary function of ST and MVT.While MVT has less trauma and lower cost.The appropriate treatment could be selected according to the clinical situation.

FREQUENCY AND FACTORS ASSOCIATED WITH INJURY TO THE AXILLARY VEIN IN WOMEN THAT UNDERWENT AXILLARY LYMPHADENECTOMY DURING BREAST CANCER SURGICAL TREATMENT / Frequência e fatores associados à lesão da veia axilar em mulheres submetidas à linfadenectomia axilar no tratamento cirúrgico do câncer de mama

Objective: To evaluate which variables are considered risk factors associated with injury to the axillary vein during lymphadenectomy in the surgical treatment of breast cancer patients. Methods: Retrospective study performed through the electronic record analysis of 1,007 patients who underwent axillary lymph node dissection at Hospital Erasto Gaertner, from January 2010 to December 2014. We assessed the following risk factors using a standard questionnaire: age, body mass index (BMI), presence of palpable axillary metastasis in the clinical examination, sentinel lymph node pre-lymphadenectomy, presence of axillary metastasis in the perioperative period, size of metastasis and if it was adhered to axillary vessels, presence of pectoralis muscle invasion, resection of the pectoralis minor muscle, axillary incision separated from breast incision, prior radiotherapy, neoadjuvant chemotherapy, and pre and postoperative staging. For each patient who presented injury to the axillary vein, we paired them with two homogeneous controls (age, BMI, preoperative staging, surgical proposal, and neoadjuvant treatment). Results: Thirteen patients had injury to the axillary vein. In the perioperative evaluation, in most of them, the axilla was positive in the injury group (10 cases = 76.9%) and control group (12 cases = 46.1%), and it was adhered to axillary vessels in 10 cases in the injury group (76.9%) and 7 in the control group (26.9%). Conclusion: In this study, the presence of axillary metastasis in the perioperative evaluation, as well as that adhered to the axillary vessels, is associated with an increased risk of injury to the axillary vein during lymphadenectomy.

Surgical treatment of Denis type B thoracolumbar burst fracture with neurological deficiency by paraspinal approach

We aimed to describe the surgical technique and clinical outcomes of paraspinal-approach reduction and fixation (PARF) in a group of patients with Denis type B thoracolumbar burst fracture (TLBF) with neurological deficiencies. A total of 62 patients with Denis B TLBF with neurological deficiencies were included in this study between January 2009 and December 2011. Clinical evaluations including the Frankel scale, pain visual analog scale (VAS) and radiological assessment (CT scans for fragment reduction and X-ray for the Cobb angle, adjacent superior and inferior intervertebral disc height, and vertebral canal diameter) were performed preoperatively and at 3 days, 6 months, and 1 and 2 years postoperatively. All patients underwent successful PARF, and were followed-up for at least 2 years. Average surgical time, blood loss and incision length were recorded. The sagittal vertebral canal diameter was significantly enlarged. The canal stenosis index was also improved. Kyphosis was corrected and remained at 8.6±1.4o (P>0.05) 1 year postoperatively. Adjacent disc heights remained constant. Average Frankel grades were significantly improved at the end of follow-up. All 62 patients were neurologically assessed. Pain scores decreased at 6 months postoperatively, compared to before surgery (P<0.05). PARF provided excellent reduction for traumatic segmental kyphosis, and resulted in significant spinal canal clearance, which restored and maintained the vertebral body height of patients with Denis B TLBF with neurological deficits.

Treatment and prognosis of 76 patients with gallbladder cancer: a single-center retrospective study / 中华肝胆外科杂志

Objective To investigate effective treatment modalities and the related factors influencing prognosis of patients with gallbladder cancer.Methods The clinical data of 76 gallbladder carcinoma patients admitted to the Department of General Surgery,PLA Nanjing General Hospital from January 2005 to October 2015 were analyzed retrospectively.Follow-up was carried out via telephone or outpatient service until January 2016.Cox regression and Kaplan-Meier models were performed for survival analysis.Results 69 patients were treated with surgery and/or postoperative adjuvant chemotherapy.The remaining 7 patients with liver or distant metastases who did not undergo surgery received chemotherapy.24 patients died from cancer relapse,37 patients died from disease progression after giving up treatment,and 7 patients were lost to follow-up.The remaining 8 patients were still alive at the time of follow-up.The depth of cancer invasion (HR =2.736),the type surgical procedure (HR =2.207),and adjuvant chemotherapy (HR =0.603) were significant impact factors of survival for GBC patients.Adjuvant chemotherapy was a protective factor.The average survival in the chemotherapy-naive group was (10.6 ± 1.9) months,the single chemotherapy group (18.5 ± 2.8) months,and the combined chemotherapy group (26.9 ± 6.4) months.There were no significant differences among these groups.Conclusions The depth of cancer invasion,types of surgical procedure particularly radical cholecystectomy,and adjuvant chemotherapy were significant factors of survival in patients with GBC.Radical cholecystectomy combined with arterial and intravenous chemotherapy using gemcitabine and oxaliplatin showed benefits in survival in GBC patients.

Risk factors of microinvasion in breast ductal carcinoma in situ / 中国肿瘤临床

Objective:To analyze risk factors of breast ductal carcinoma in situ (DCIS) with microinvasion (DCIS-MI) and explore suitable axillary lymph node surgery treatment for patients with DCIS-MI. Methods:The clinical characteristics, such as age, menopausal status at diagnosis, size of breast mass, and pathology reports of 45 patients with breast DCIS or DCIS-MI treated at Jinling Hospital, Medical School of Nanjing University from February 2013 to February 2016, were retrospectively collected and analyzed statistically to deter-mine the risk factors associated with microinvasion. Results:Premenopause (P=0.006), tumor size≥3.15 cm (P=0.006), and family his-tory of malignant tumor (P=0.002) were proven risk factors of DCIS-MI. Conclusion:Patients with clinical palpable axillary mass, pre-menopause, large breast mass, and family history of malignant tumor demonstrated high possibility of DCIS-MI. Hence, sentinel lymph node biopsy should be performed. Axillary lymph node dissection is highly recommended to patients whose main symptom is palpable axillary mass.

Results of the otosclerosis surgery treatment / Шинэ санаа Шинэ нээлт

Otosclerosis is a disease that involves the cochlea and it is developed when the structure ofconnecting tissue in the area of stapedius and the oval window has changed and become unmovable.Consequently, conductive hearing loss and therefore severe sensorineural hearing loss are caused.The causes of otosclerosis have not been discovered yet but many factors impact on this disease. Anyresearch works has not been done on otosclerosis in Mongolia until now and we have conducted theresearch in 2008-2013. Therefore, we aimed to identify the hearing condition after surgery treatmentof otosclerosis.41 patients /47 ears/ who were diagnosed of having otosclerosis with conductive hearing loss, nomiddle ear infection through the comprehensive ear and hearing examinations were selected in thisstudy which was done at EMJJ Clinics between 2007 and 2013. The hearing improvement after thesurgery has been tested under bone and air conduction frequency 500, 1000, 2000, 4000, 8000 Hzand the results before and after the surgery were statistically processed on Excel 2010 and SPSS 17.0software programs. Stapedotomia and Stapedoectomia surgery approaches were applied and afteropening of attics, the hearing bones are palpated and the diagnosis of stapes otosclerosis is confirmedby the surgeon, who removes the stapes. Then a titanium K-piston (prosthese or implant) is thenplaced into this opening and connected to the malleus, or the incus.Out of 41 patients (85.4% female) involved in the study and 36 people had one ear side otosclerosisand 5 people had both ear otosclerosis. After the surgery 25 patients did not have dizziness andvomiting symptoms and 14 patients did not have dizziness with movement after 12 hours, andfor 4 patients all symptoms were disappeared after 24 hours. As for the result from the hearingexamination after 21, 60 days of the surgery, bone conduction was normal, air conduction, andhearing for 32 patients improved completely, and after 120 days of the surgery, the hearing of 33patients improved completely, bone conduction became 2000 Hz at 4000 Hz frequency 12-15 dB,average of air conduction 15,4±10,1 dB, bone-air gap 10,4±3,1 dB for 5 people, and bone conduction2000 Hz-4000 Hz, at 8000 Hz frequency 20-40dB, air conduction became 25-45dB 10,4±5,1db for 9patients and all patients had no hearing loss except for 4 people who still had tinnitus.After surgery stapedotomia and stapedoectomia for the otosclerosis, the hearing improvement was95.2% and it has been concluded that there is full possibility to perform surgeries of stapedotomia andstapedoectomia for the otosclerosis in Mongolian situation.

Significance of the MELD scoring system in surgical treatment of obstructive jaundice / 中华肝胆外科杂志

Objective To prospectively study the clinical significance of the MELD scoring system in surgical treatment of obstructive jaundice.Methods 112 patients with obstructive jaundice who were admitted into our hospital from January 2009 to December 2013 were divided into two groups:group A (Stage Ⅰ PTCD and stage Ⅱ open operation,n =53) and group B (1 stage open surgery,n =59).The amount of intraoperative bleeding blood loss,operation time,postoperative complications,duration of hospitalization,mortality rate,and the changes in liver function after surgery were compared between the two groups.Results The differences in the liver function index of the two groups on the same postoperative date were significantly different (P ＜ 0.05).The liver function of group A recovered faster than group B.Patients in group A with a MELD ＜ 10 points stayed in hospital significantly longer when compared with patients in group B.For patients in group A with MELD ＞ 10 points,the operation time,bleeding volume,postoperative complications and hospitalization were significantly less than the patients in group B (P ＜ 0.05).There were 3 patients (group B) who died with MELD ≥ 20 points after operation.Conclusions In patients with obstructive jaundice with a MELD score greater than 10 points,especially those with a score equal to or greater than 20,PTCD should be performed first to relieve biliary tract obstruction,followed by a stage Ⅱ open surgical operation after the liver function had improved.MELD had important clinical significance in the evaluation of operation risk in patients with obstructive jaundice.

Anomalías craneofaciales / Craniofacial abnormalities

Las malformaciones craneofaciales son algunas de las patologías más prevalentes en la edad pediátrica. Podemos distinguir dos grandes grupos: las producidas por un cierre precoz de las suturas del esqueleto craneofacial, las craneosinostosis y faciocraneosinostosis; y las que actualmente se pueden considerar neurocrestopatías, como los síndromes de primer y segundo arcos branquiales y las fisuras orofaciales como la fisura labiopalatina. Se describen las principales características de los síndromes más frecuentes y los tratamientos, desde los más empleados a los más innovadores, como las técnicas endoscópicas y las de distracción ósea.

Craniofacial abnormalities are some of the most prevalent malformations in children. We can distinguish two groups: those caused by an early closure of the sutures of the craniofacial skeleton, as craniosynostoses and faciocranioynostosis; and those that are considered neural crest anomalies, like the first and second brachial arch syndromes, and cleft lift and palate. The authors discuss the major characteristics of the most frequent syndromes, as well as treatment modalities, including the most popular and the most recent ones, like endoscopic and bone distraction techniques.
