RESUMEN

BACKGROUND: The dorsal cutaneous appendage or so-called human tail is considered to be a cutaneous marker of underlying occult dysraphism. CASE PRESENTATION: We are presenting an unusual case of spinal dysraphism with a bony human tail at midthoracic region occurring in a newborn baby with tethered cord (conus at L4). Physical examination was unremarkable except for a thoracic appendage and a dermal sinus over coccyx region. Magnetic resonance imaging (MRI) scan of spine revealed bony outgrowth arising from D7 posterior element with multiple butterfly-shaped vertebrae found at D2 D4 D8 D9 D10 with low-lying conus at L4-L5 level. Surgical excision of the tail and untethering of the spinal cord along with excision of dermal sinus were performed. The infant had an uneventful postoperative period and was unchanged neurologically. CONCLUSION: To our knowledge, no similar case has been reported in English literature till date. DISCUSSION: The specific features of this rare case of human tail treated surgically are discussed in light of the available literature.

RESUMEN

Recent studies have consistently reported the safety and effectiveness of early spinal instrumentation for pyogenic spondylodiscitis. However, none of these studies investigated the recurrence rate or associated factors based on this specific group of patients. Recurrence prediction models that are not based on a homogenous cohort of patients undergoing early spinal instrumentation show theoretical limitations for clinical use. A nationwide, population-based, retrospective cohort study using a claims database was planned to investigate the recurrence rate and its associated factors in patients who underwent early instrumented spinal fusion surgery for pyogenic spondylodiscitis. We used data from the Korean National Health Insurance claims database collected between 2014 and 2018. A total of 2148 patients who underwent early (within 6 weeks after the diagnosis) instrumented spinal fusion surgery for pyogenic spondylodiscitis were included, including 1925 patients (90%) without recurrence and 223 patients (10%) with recurrence. Logistic regression models were used to identify factors associated with recurrence, and sensitivity analysis was performed according to two different definitions for recurrence: shorter (2 weeks or more) and longer (6 weeks or more) periods of antibiotic therapy for recurrence. The recurrence rates in our cohort were 14.1%, 10.4%, and 8.0% at 2, 4, and 6 weeks, respectively, in relation to the duration of antibiotic treatment for recurrence. We identified age 60−69 years (OR = 2.42), age > 70 years (OR = 2.29), posterior thoracic approach (OR = 1.85), multiple surgical approaches (OR = 4.17), use of a cage (OR = 1.66), transfusion (OR = 2.55), antibiotics for resistant organisms (OR = 2.55), and systemic steroid treatment over 2 weeks (OR = 2.27) as the factors associated with recurrence. The recurrence rates and associated factors from our first population-based and the largest clinical study can be practically used as a reasonable reference and provide clinicians with an acceptable tool for the comprehensive risk assessment for recurrence after early spinal instrumentation for pyogenic spondylodiscitis.

RESUMEN

Pilar cysts, a subtype of sebaceous cysts, are benign masses often commonly found on the scalp, back, and face. They are common amongst women and carry a low potential for malignancy. These lesions arise due to the buildup of keratin in the skin pore, blocking the exit port of sebaceous gland secretions. The buildup of keratin material ultimately leads to cyst formation. The complications of these cysts include inflammation, rupture, infection, and transformation to cancerous lesions in some rare instances. This is a case of a 59-year-old female with a long-standing history of recurrent complicated pilar cysts who presented to the outpatient surgical clinic for assessment of cysts for removal. A total of eleven cysts were successfully removed through two separate surgeries.

RESUMEN

INTRODUCTION: Forearm non-unions pose a significant treatment challenge to orthopedic surgeons. Repetitive treatment failures can lead to a devastating situation for the patient. Forearm function influences both elbow and wrist proper function. CASE REPORT: A functionless hand is presented, describing a longstanding non-union, treated with multiple surgeries before. A thorough debridement with respect to blood supply and local biology are of major importance before applying the locking plates along with the use of bone-graft. The reconstruction of the forearm converted a functionless arm to a fully functioning arm and the patient returned eventually to her previous activities. CONCLUSION: Fixation with locking plates combined with the use of autograft can lead to very satisfactory results even in extraordinary cases, especially when attention is paid to local anatomy and blood supply.

RESUMEN

Poorly differentiated gastric adenocarcinoma is commonly associated with lymph node metastasis, peritoneal spread, and liver metastasis but rarely with intraintestinal metastasis. Most patients with metastatic gastric carcinoma are unable to undergo surgical treatment and have a poor prognosis. A 42-year-old man with hunger-related abdominal pain was diagnosed as having gastric cancer. After the first surgery (distal partial gastrectomy) and the second surgery (gastric stump carcinoma (GSC) resection), the patient suffered repeated multiple intracolonic metastases and underwent three additional resection operations. The patient survived for 154 months after the first operation. In patients with gastric carcinoma that metastasizes to the colonic lumen, radical resection, if possible, can extend survival. Once patients develop extensive extraintestinal metastasis, radical resection cannot be performed, and patients often exhibit a poor prognosis.

RESUMEN

BACKGROUND: One of the major complications in endoscopic endonasal skull base surgery (EESBS) is postoperative cerebrospinal fluid (CSF) leaks. Recently, EESBS has been applied to various skull base diseases as well as more complicated cases influenced by previous treatment with or without various comorbidities. AIMS/OBJECTIVES: This study aimed to assess the factors that influence the results of postoperative CSF leak after EESBS with mixed patient backgrounds. MATERIALS AND METHODS: We conducted a retrospective analysis of the clinical records of patients undergoing EESBS in our institution from 2012 to 2017. RESULTS: Out of a total of 230 cases of EESBS, 11 (4.8%) suffered from postoperative CSF leakage. The rate of CSF leakage for pituitary adenoma, Rathke's cleft cyst, chordoma, and meningioma was 3.5%, 0%, 3.6% and 8.0%, respectively. Multiple variate analysis revealed that repeated surgery (p = .008) and intraoperative CSF leak (p = .044) were significant risk factors for postoperative CSF leakage. CONCLUSIONS AND SIGNIFICANCE: The rate of postoperative CSF leakage in this study was comparable to previous reports, and repeated surgery may increase postoperative CSF leakage. The surgical strategy for tumor removal as well as skull base reconstruction should be given careful consideration according to tumor pathology and the patient's condition.

RESUMEN

OBJECTIVE: Patients affected with von Hippel-Lindau disease often develop multiple hemangioblastomas in the cerebellum and spinal cord. Timing of surgical intervention is difficult and depends largely on the anticipated surgical morbidity. However, data regarding surgical outcome after multiple cerebellar and medullary surgeries are scarce. Our objective was to evaluate cumulative surgical morbidity in patients operated on multiple cerebellar and medullary hemangioblastomas and to deduce recommendations for treatment. METHODS: We performed a retrospective analysis for a consecutive cohort of von Hippel-Lindau patients with surgical treatment of at least two cerebellar and/or medullary hemangioblastomas. Pre- and postoperative functional grades were reviewed in patients' files and compared by Modified Ranking Scale (cerebellar surgeries) or by Modified McCormick Score (medullary surgeries). RESULTS: Thirty-six patients were surgically treated for at least two cerebellar hemangioblastomas (12 patients), at least two medullary hemangioblastomas (19 patients) or at least two hemangioblastomas in both locations (5 patients). Fourthy-eight cerebellar and 80 medullary procedures were performed in total. On average, multiple cerebellar surgeries caused no clinical deterioration, whereas multiple medullary surgeries led to a slight cumulative deterioration of postoperative functional grades. The severity of this deterioration did not correlate to the number of performed medullary surgeries. CONCLUSION: Resection of multiple cerebellar hemangioblastomas is not associated with cumulative morbidity. Although there is a certain cumulative surgical morbidity caused by medullary surgeries, its extent does not increase with the number of performed surgeries. Microsurgical removal of asymptomatic tumors with radiographic progression can also be considered for patients with multiple tumors and previous surgeries.

RESUMEN

OBJECTIVES: Recurrent Respiratory Papillomatosis (RRP) is a rare disease caused by the human papilloma virus that presents as warty, exophytic growths in the upper airway. RRP in the larynx can lead to severe airway obstruction and voice changes. It is clinically known that patients with RRP frequently experience dysphonia. The purpose of this study was to assess the impact of multiple surgical treatments on RRP patients' voice outcomes, and to determine whether a higher number of repeated surgeries lead to decreased voice quality. METHODS: A retrospective cohort study was conducted of adult RRP patients (n = 23) who underwent multiple surgeries. Group 1 included patients (n = 11) who had <5 surgeries (range 2-4 surgeries) and Group 2 included patients (n = 12) who had ≥5 surgeries (range 5-50+ surgeries). Voice recordings were selected from the following clinic visits: initial office visit (initial presurgery), first postsurgery, and the last clinic encounter(s) with no immediate planned surgery. Blinded auditory-perceptual ratings along with cepstral and spectral acoustic measures assessed voice severity. RESULTS: There was significant improvement from the initial presurgery visit compared to each postoperative visit over time for all voice outcome measures for both Group 1 and Group 2. The results of the study indicated that the number of surgeries did not significantly affect mean postoperative voice outcomes, and there were no significant differences between patient groups for voice quality over time. CONCLUSIONS: The results of this study suggest that RRP patients' voice quality may not suffer cumulative negative effects when using modern tissue-sparing surgical techniques.

RESUMEN

PURPOSE: The purpose of this study is to report our short-term functional outcome for 14 children with arthrogryposis multiplex congenita (AMC) who underwent multiple surgical procedures at an early age. METHODS: During the period 2002-2010, 14 children (11 males and three females) with AMC underwent multiple surgical procedures to treat deformities of the lower and upper limbs. About 81 procedures were performed, at a rate of 5.9 procedures per child. The mean age at the last follow-up was 5.9 years. The average follow-up period was 3.6 years (range, 1.5-6 years). The functional outcome assessment included walking ability and the activities of daily living for the upper limb function. RESULTS: At the last follow-up visit, six (43%) children (four males, two females) with a mean age of 8.3 years (range, 4-15) were independent walkers. Three children (males) with a mean age of 3.5 years (range, 2.5-5) were able to walk, but with support. One child (male), 3 years old, was a household ambulator. Three children (two males, one female) with a mean age of 4.2 years (range, 2.5-6) were nonfunctional ambulators. The last child (male) was nonambulatory at the age of 5 years. Activities of daily living were severely affected in the nonambulatory child. One child in the nonfunctional ambulators group had limitations in the activities of daily living; however, upper limb function was not affected in the remaining 12 children. CONCLUSION: We believe that aggressive surgical treatment using multiple operations at an early age can improve the short-term functional and clinical outcomes of children with AMC.
