RESUMEN

OBJECTIVE: To assess the effects of mini-implant assisted micro-osteoperforations (MI-MOPs) in the alignment of mandibular anterior teeth, and to explore the intervention's associated pain perception (PP) and root resorption (RR) in adults treated by fixed appliance. DESIGN: Multicentre, two-arm and single-blinded randomised clinical trial. SETTING: College of Dentistry, University of Baghdad. PARTICIPANTS: Adolescents (mean age = 18.97 years) undergoing non-extraction orthodontic therapy for the management of mandibular anterior crowding. METHODS: A total of 33 participants (mean age = 18.97 years) undergoing non-extraction orthodontic therapy for the management of moderate mandibular anterior crowding were allocated to the experimental (MI-MOPs, n = 17) or control groups (non-MI-MOPs, n = 16). A series of lower study models were obtained at week 4 (T1), week 8 (T2) and week 12 (T3) in the MI-MOPs group and continued to week 16 (T4) and week 20 (T5) in the non-MI-MOPs group, with all models analysed digitally. Periapical radiographs (PA) were taken before commencing treatment (T0) and T3. Participants were asked to complete a 10-point visual analogue scale (VAS) daily during the first week of treatment. RESULTS: At T0, the mean Little irregularity index (LII) was 5.1 mm (95% confidence interval [CI] = 4.95-5.23) with no statistically significant difference between groups (P = 0.766). At T1, T2 and T3, t-test showed statistically significant differences in the LII (P < 0.05) in favour of the MI-MOPs group; mean differences (MD) were -1.16mm (95% CI = -1.36 to -0.96), -1.77 mm (95% CI = -1.93 to -1.59) and -1.58 mm (95% CI = -1.67 to -1.48), respectively. Mean treatment time from baseline to final alignment was 10.41 weeks (95% CI = 9.92-10.89) in the MI-MOPs group and 16.62 weeks (95% CI = 16.11-17.13) in the non-MI-MOPs groups, which was statistically significant (MD -6.21 mm, 95% CI = -6.88 to -5.53, P < 0.05). Conversely, Mann-Whitney U-test and Wilcoxon signed-rank test showed no significant differences in terms of PP and RR between the groups (P > 0.05). The participants in the MI-MOPs group experienced a higher degree of RR (P < 0.05) secondary to intervention. No other significant adverse events were reported during the trial. CONCLUSION: This trial found that combining MI-MOPs with non-extraction-based fixed orthodontic therapy in adults mildly shortens the duration of the alignment phase. RR should be monitored throughout the treatment when using MI-MOPs (ClinicalTrials.gov NCT04778241).

RESUMEN

OBJECTIVES: To investigate the effect of vitamin D3 level on the alignment of mandibular anterior teeth in adults and explore the associated root resorption and pain perception. Trial Design. Multicentre, double blinded randomized clinical trial. Subjects and Methods. Adult patients aged 18-30 years, with moderate mandibular incisor crowding [Little's Irregularity index (LII) 3-6 mm], needing nonextraction treatment with fixed orthodontic appliance, were randomly allocated into two groups with 1 : 1 allocation ratio. In the 1st group (normal vitamin D3 level group [ND3G]), vitamin D level was measured and corrected to normal before starting orthodontic treatment, while in the 2nd group [control group (CG)] the vitamin D level was kept unknown until completion of the alignment phase. Outcome measures included mandibular incisor crowding using LII, orthodontically induced root resorption (OIRR), and pain perception. Independent sample t-test was used to compare the duration of treatment, the effectiveness of alignment, and OIRR between groups, while differences in pain perception were analysed by Mann-Whitney U-test (P < 0.05). RESULTS: Out of 87 patients recruited from four centres, 33 patients were randomly allocated into two groups (17 patients to ND3G and 16 patients to CG). Time elapsed for the complete alignment of the mandibular incisor crowding was one month shorter in ND3G (23.532% faster), and the improvement percentage was significantly higher in all periods when compared to the CG. The amount of OIRR was not significantly different between groups; however, pain during the first three days of alignment was significantly less in ND3G. CONCLUSIONS: Having optimal vitamin D3 level reduced the alignment time and pain associated with orthodontic treatment, but it had no role in reducing OIRR. Registration. The trial was registered with ClinicalTrials.gov on 12th April 2021 (registration number: NCT04837781).

RESUMEN

OBJECTIVES: The aim of the present study was to investigate the trends in the use of fixed appliance and accelerated orthodontics to decrease the treatment duration. Further, this study aimed to assess the effect of demographic factors on the participant's choice of treatment modality. METHODS: This was a cross-sectional study in the form of questionnaire-based online survey especially designed and distributed to 265 orthodontists via email. The questions aimed to collect basic information about the participants and respondents' choices for decreasing the treatment duration. The data were analyzed according to gender, level of academic education and years of clinical experience using Chi-square test. RESULTS: A response rate of 85.2% was reported. Most of the orthodontists aimed to reduce the treatment duration by the biomechanical (66.8%) and surgical approaches (27.4%). The use of sliding mechanics (69.4%) and one-step retraction was more common (66.3%). MBT bracket prescription was more prevalent (51.7%), followed by Roth (41.1%). Conventional brackets were used more than self-ligating brackets, and aesthetic brackets were avoided by one third of the respondents. NiTi wires were the most commonly used wires during the alignment stage (44.2%). However, the effect of gender, years of clinical experience and specialty level of education showed some effects on the use of certain techniques and clinical practice of the respondents. CONCLUSIONS: Most of the orthodontists aimed to decrease orthodontic treatment duration by using biomechanical and surgical approaches. Gender and clinical experience to a certain extent affected the participants' choice during orthodontic treatment.

RESUMEN

Background/Purpose. In the literature, no consensus about the duration of orthodontic treatment has been reached out. This study aimed to identify orthodontist's and patient's perception about the time of orthodontic treatment and their willingness to undergo and pay for various acceleration techniques and procedures. Materials and Methods. An electronic survey was conducted from August to October 2020. The questionnaire consisted of 20 multiple choice questions which was designed and emailed to members of the Iraqi Orthodontic Society and self-administered to patients in several orthodontic centers in Baghdad. The questionnaire included questions about the perception toward the duration of orthodontic treatment, approval of different procedures used to reduce treatment time, and how much fee increment they are able to pay for various techniques and appliances. Descriptive and chi-square test statistics were used, and the level of significance was set at p ≤ 0.05. Results. The response rate was 78.7%. The willingness for additional techniques and procedures was rated in the following order: customized appliances: 50.8% orthodontists and 38.4% patients, followed by intraoral vibrating devices: 49.2% orthodontists and 38.1% patients, piezocision: 10.2% orthodontists and 8.2% patients, and corticotomies: 8.1% orthodontists and 5.9% patients. Most orthodontists were willing to pay up to 40% of treatment income for the acceleration procedure, while the payment of patients was up to 20%. Conclusion. Both orthodontists and patients were interested in techniques that can decrease the treatment duration. Noninvasive accelerating procedures were more preferable by orthodontists and patients than invasive surgical procedures.

RESUMEN

BACKGROUND: To identify the most common retention protocols practiced by Iraqi orthodontists using a specially designed e-survey. Furthermore, this study aimed to assess the effect of sociodemographic factors on the participant's choice. METHODS: Two hundred and twenty-five questionnaires with 23 multiple choice questions were sent to members of the Iraqi Orthodontic Society. The questionnaire was organized into four sections representing information about sociodemographic status of the orthodontists, factors affecting the selection of the retention system, commonly used retainers in the upper arch and lower arch, and duration of the retention system. The chi-square test was used to test the significant association between different variable and sociodemographic factors. RESULTS: The response rate was 87.5%. The majority of the respondents considered the original malocclusion (80.2%) and clinical experience (49.7%) as the main factors for choosing the retention protocol. In the maxillary arch, a combination of vacuum-formed retainer and fixed retainer (35%) was mostly applied; in the mandibular arch, a fixed retainer was mainly used (46.7%). Most of the respondents recommended initial full-time wearing of a removable appliance (78.2%), especially in the first 3-6 months (47.2%). According to the respondents, bonding a fixed retainer to all anterior teeth was most common (79.7%), fabricated, and adapted directly inside the patient's mouth (75.1%). More than half used flowable composite (54.8%) and recommend leaving the retainer forever (53.8%). Most of the variables showed a statistically significant association between the sociodemographic factors and type, duration, and fabrication of the retainer used. CONCLUSIONS: A combination of removable and fixed retainers was commonly used in orthodontics retention, and sociodemographic factors significantly affected retainer choice.

RESUMEN

OBJECTIVE: Kaposi's sarcoma (KS) is an angioproliferative disease frequently seen in patients with the acquired immunodeficiency syndrome (AIDS). Previous studies suggest that the HIV-1 protein Tat and Fibroblast Growth Factor 2 (FGF-2) have synergistic angiogenic effects in AIDS-KS tumors. However, the mechanisms by which FGF-2 is released and activated in KS tumors are not clearly defined. We carried out this study to determine whether an FGF-binding protein (FGFBP1 or BP1) that enhances the angiogenic activity of FGF-2 is expressed in AIDS-KS tumors, and to define whether BP1, FGF-2, and HIV-Tat protein-protein interactions could play a potential clinically role in the pathogenesis of AIDS-KS. METHODS: BP1 was localized in AIDS-KS lesions by immunohistochemistry and in situ hybridization studies. The binding of radiolabeled FGF-2 to His-tagged BP1 or the FGF-receptor 1 was assessed in the presence and absence of HIV-Tat and other viral proteins. Mice carrying tetracycline-regulated BP1 transgene mice were used to determine whether activation of BP1 during wound healing induces KS-like lesions. RESULTS: BP1 expression was detected in AIDS-KS tumor keratinocytes, spindle cells, and infiltrating mononuclear cells. In addition, HIV-Tat competed for the binding of FGF-2 to immobilized BP1, but does not affect the interactions of FGF-2 with its high affinity receptor (FGFR-1). In contrast, two other HIV-proteins, Nef and gp120, did not affect the binding of FGF-2 to BP1 or to FGFR-1. Finally, up-regulation of BP1 expression in tetracycline-regulated -conditional BP1 transgenic mice subjected to skin wounds, induced KS-like skin lesions. CONCLUSION: Taking into consideration the results of previous studies showing that both HIV-Tat and BP1 enhance the mitogenic and angiogenic activity of locally-stored FGF-2, both in vitro and in vivo, our findings suggest a novel mechanism by which the release and activity of FGFs can be modulated in AIDS-KS tumors by HIV-Tat as well as BP1.

RESUMEN

BACKGROUND: Acellular dermal matrix has been used for over a decade in primary breast reconstruction. Few articles have specifically examined its use in revision breast reconstruction for fold malposition, capsular contracture, rippling, and symmastia. METHODS: One hundred thirty-five revision breast reconstructive procedures using acellular dermal matrix (AlloDerm) in 118 patients (154 breasts) over a 5-year period were reviewed. Most procedures were revisions or part of the second stage of previous mastectomy reconstructions; three were revisions after reconstruction of congenital chest wall deformities. RESULTS: Fifty-seven revisions (37 percent) were for inferior fold malposition, followed by 40 (25.9 percent) for inferior pole support, 42 (27.2 percent) for capsular contracture, 10 (6.4 percent) for rippling, and five (3.2 percent) for symmastia. The overall complication rate was 5 percent. Revisions with acellular dermal matrix were successful in 147 of 154 breasts (95.5 percent). The most common complication was capsular contracture, occurring in five breasts (3.2 percent). There was one infection (0.6 percent), failure to lower the inframammary fold in one breast (0.6 percent), and one persistence of rippling (0.6 percent). The mean follow-up was 207 days. CONCLUSIONS: Acellular dermal matrix has proven to be a reliable tool for managing some of the most common and challenging problems in implant-based breast reconstruction. Although there are few published data on the success of more conventional solutions to fold malposition, lower pole support, and capsular contracture, the addition of acellular dermal matrix to buttress these repairs has been shown to provide a high likelihood of success with a low risk of complications.

RESUMEN

BACKGROUND: Although acellular dermal matrix materials have been in use for over a decade in primary and secondary breast reconstruction and in some cosmetic breast surgery, little has been published on the outcomes of these materials for cosmetic applications. METHODS: A retrospective institutional review board-approved review was conducted of all patients who had a specific acellular dermal matrix, Strattice, used for cosmetic breast surgery performed by the senior author (S.L.S.). Patient demographics, indications, surgical findings, and postoperative course were collected and data analyzed using descriptive statistical tools. RESULTS: Between 2008 and 2012, Strattice was used in 43 cosmetic breast operations (75 breasts) performed by the senior author (S.L.S.). Sixty-nine of the 75 breasts (92 percent) were revision operations. Indications included inferior pole support [39 breasts (52 percent)], fold malpositions [28 breasts (37 percent)], capsular contracture [25 breasts (33 percent)], and rippling/palpability [six breasts (8 percent)]. Three patients (six breasts) had Strattice placed during primary augmentation/mastopexy. Seventy-four of the 75 breasts (98.7 percent) had successfully achieved the indication for which the Strattice was placed; one breast (1.2 percent) had some degree of relapse. The global complication rate for all patients in this study is 5.3 percent-two breasts (2.7 percent) had postoperative malposition, one breast (1.2 percent) had bottoming out, and one breast (1.2 percent) developed an infection that resulted in temporary device explantation. CONCLUSIONS: The use of Strattice is safe and may be helpful in the management of certain situations in cosmetic breast surgery, including needed lower pole support, capsular contracture, rippling, and implant malposition. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

The high-riding nipple-areola complex is a clinical problem that can be encountered following cosmetic and reconstructive breast surgery. Because of the desire to avoid scars on the superior aspect of the breast and the limited availability of superior breast skin, it can be technically challenging to place the nipple-areola complex in a lower position. Multiple surgical strategies have attempted to lower it, and each has its advantages and disadvantages. Reciprocal rotation flaps have been used by the authors with success. They describe the surgical technique and outcomes in five breasts. The medical records of all patients who had reciprocal rotation flaps for high-riding nipple-areola complexes performed by the senior author (S.L.S.) were reviewed. The institutional review board-approved review included preoperative history and examination, surgical findings, surgical technique, and postoperative course. Five reciprocal rotation flap procedures were performed on four patients between 2005 and 2012 for high-riding nipple-areola complexes. The high-riding nipple-areola complexes were all iatrogenic, following reconstruction for nipple-sparing mastectomy or mastopexy. All nipple-areola complexes were successfully lowered with an average follow-up duration of 2.1 years. One breast that had undergone previous radiation therapy had a nipple-areola complex flap that appeared ischemic; the patient underwent hyperbaric oxygen therapy and the flap fully survived. Reciprocal rotation flaps are an effective strategy for management of the high-riding nipple-areola complex and can be safely performed with thoughtful planning and careful surgical technique. This technique is riskier in the irradiated breast but may be facilitated with hyperbaric oxygen therapy.

RESUMEN

BACKGROUND: Postoperative nipple malposition can be an aesthetically devastating problem for patients and a formidable challenge for surgeons. The authors' aim was to identify the common antecedent events leading to high-riding nipples, provide a classification system for these problems, and discuss management. METHODS: A retrospective review of medical records was conducted for patients who presented to the senior surgeon (S.L.S.) for management of a postoperative, excessively high nipple-areola complex over an 8-year period from January of 2004 to March of 2012. Demographic information, medical histories, operative details, and office records were reviewed for each patient. The high nipple-areola complex was classified as mild, moderate, or severe depending on the distance from the superior breast border to the top of the nipple-areola complex in relation to the vertical breast height. RESULTS: Twenty-five women met study criteria, with 41 breasts determined to have an excessively high nipple-areola complex. The average patient was aged 44.3 years and had undergone 2.5±1.3 operations before the development of a notably high nipple-areola complex, including nipple-sparing mastectomy (32 percent), augmentation/mastopexy (29 percent), augmentation (27 percent), mastopexy (10 percent), and skin-sparing mastectomy with nipple reconstruction (2 percent). Patients were classified as having mild (27 percent), moderate (56 percent), or severe (17 percent) nipple-areola complex displacement; surgical correction was attempted in 54 percent of cases. CONCLUSIONS: A high-riding nipple-areola complex can develop following aesthetic or reconstructive surgery. Although many patients may not need or choose correction, there are surgical options that may be helpful in improving the nipple-areola complex position.

RESUMEN

Prosthetic-based breast reconstruction commonly involves device placement in either a total submuscular pocket or a partial subpectoral position for just superior pole coverage, with various possible strategies for inferior pole coverage. Historically, the pectoralis major muscle is managed either by suturing the muscle to the inferior flap or with marionette sutures; alternatively, the device is placed under total muscle/fascia coverage (under the pectoralis major, plus the serratus anterior and rectus abdominis muscles or fascia). For many plastic surgeons, acellular dermal matrix is now used instead to function as a sling or "hammock" supporting the periprosthetic pocket and thus covering the inferior pole of the device, attached to the pectoralis major muscle above and to the inframammary fold below. In addition to its added soft-tissue support in the inferior pole, acellular dermal matrix may help to stabilize the pectoralis major muscle along its inferolateral margin, create a well-defined inframammary fold, provide the opportunity to significantly increase intraoperative fill volume of the tissue expander, and reduce the incidence or severity of significant or symptomatic capsular contracture, particularly in a patient whose breast has been treated with radiation. In addition to its indications in primary breast reconstruction, acellular dermal matrix has been increasingly used in secondary revision reconstruction cases. It can be used to buttress capsulorrhapy and capsulotomy sites and it can be used to replace periprosthetic capsule following capsulectomy. While clinical experience is accruing for these indications, acellular dermal matrix continues to be used in primary and secondary breast reconstruction.

RESUMEN

BACKGROUND: Late seromas surrounding breast implants are becoming an increasingly important issue in breast surgery. The authors report their experience with late seromas and describe their previous management options. METHODS: A multicenter retrospective review of patients who developed late seromas (clinically presenting seromas without evidence of overt or documented infection more than 1 year after implant operation) was performed. Management, surgical technique, outcomes, complications, culture findings, and cytology results were recorded. RESULTS: Between 2005 and 2010, 28 late seromas were identified in 25 patients. The average interval from the patient's last surgery to seroma onset was 4.7 years; 27 of 28 breasts (96 percent) had a Biocell textured device in place at the time of seroma development. The late seromas in the series were managed as follows: 15 (53.6 percent) by complete capsulectomy, seroma drainage, and new implant placement; three (10.7 percent) by seroma drainage and new implant placement but without capsulectomy; two (7.1 percent) by complete capsulectomy and seroma drainage but without implant replacement; five (17.9 percent) by only ultrasound-guided seroma drainage without the need for surgical intervention; and three (10.7 percent) by antibiotic therapy alone. All cultures and cytology studies were negative for malignancy or infection; 27 of 28 seromas (96 percent) were treated successfully by one of the described approaches. CONCLUSIONS: Biocell textured implants were more likely to be associated with late seromas than were smooth shell implants. The overwhelming majority of late seromas appear to be idiopathic, without clear evidence of infection or malignancy. A graduated approach, including several different management strategies, was used to successfully manage these patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

BACKGROUND: Nipple-sparing mastectomy remains controversial and its adoption has been slow because of oncologic and surgical concerns. METHODS: A retrospective study evaluated all nipple-sparing mastectomies performed at a single institution for therapeutic or prophylactic indications for which records were available. RESULTS: Between 1989 and 2010, 162 nipple-sparing mastectomies were performed in 101 women. Forty-nine (30 percent) were performed for therapeutic purposes on 48 patients. A subareolar biopsy specimen was taken in 39 of 49 breasts (80 percent); four (10 percent) revealed ductal carcinoma in situ, and the nipple or nipple-areola complex was later removed. Four of 49 breasts (8 percent) in the therapeutic group had ischemic complications involving the nipple-areola complex, one of which (2 percent) was excised. With a mean follow-up of 2 years 6 months (range, 5 months to 9 years 5 months), no patients developed cancer in the nipple-areola complex. The remaining 113 mastectomies (70 percent) were performed prophylactically on 80 patients. The subareolar tissue was biopsied in 80 breasts (71 percent). One biopsy revealed lobular carcinoma in situ; none had ductal carcinoma in situ or invasive cancer. Two nipple-areola complexes (1.8 percent) were ischemic and excised. With a mean follow-up of 3 years 7 months (range, 5 months to 20 years 6 months), no patients developed new primary cancers in the nipple-areola complex. CONCLUSIONS: Nipple-sparing mastectomy can be safe in properly selected patients. A subareolar biopsy can effectively identify nipple-areola complexes that may harbor cancerous cells. Ischemic complications resulting in nipple loss can be minimized, and long-term follow-up suggests that this technique deserves further investigation in properly selected patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

OBJECTIVE: Limb salvage in the diabetic population is complex, controversial, costly and variable throughout the world. Within the diabetic population, the indications and morbidity surrounding major leg amputation have not been well defined. RESEARCH DESIGN AND METHODS: A retrospective study of the Georgetown Limb Salvage Registry was conducted to determine outcomes in diabetic patients undergoing proximal forefoot/midfoot (PF/M) amputations and to help define the indications for major leg amputation in ambulatory diabetic patients. RESULTS: Of the 937 ambulatory diabetic patients identified during this time period, 808 who presented with superficial ulcers or distal forefoot disease and who did not go on to PF/M or higher amputation were eliminated. Records of 88 patients (92 limbs) in the PF/M amputation group and 25 patients in the below the knee amputation (BKA) group were reviewed (no above knee amputations were performed). At 2 years in the PF/M amputation group, 80% (70/88) of patients were still alive, 73% (68/92) of the limbs remained intact, and 64% of patients (56/88) were ambulatory. In contrast, in the BKA population at 2 years, 52% (13/25) of patients were deceased and 64% (16/25) were ambulating with a prosthetic limb (or had been ambulating at the time of death). The only statistically significant difference between these two groups was the presence of Charcot collapse and rear-foot disease in the BKA group. CONCLUSION: Aggressive efforts at salvage with PF/M amputation procedures should be entertained prior to higher level amputations due to the increased morbidity and mortality evidenced.

RESUMEN

INTRODUCTION: With increasing indications for and volume of patients undergoing peripheral nerve surgery, it becomes imperative that complication rates are monitored. This study looks at complication rates in all types of peripheral nerve surgery, develops a complication classification system, and defines the most common variables associated with failures and complications. METHODS: All peripheral nerve procedures performed by the senior author during a consecutive 6-year period were retrospectively reviewed. Complications occurring within the first 30 postoperative days were recorded and classified into minor, intermediate, or major. RESULTS: A total of 5219 procedures were performed on 1819 patients in all areas of the body (head and neck, trunk, and upper and lower extremities). The total complication rate was 2.91%, with a minor complication rate of 2.47%, intermediate complication rate of 0.44%, and major complication rate of 0%. CONCLUSIONS: This study confirms that peripheral nerve surgery can be safely performed with a very low complication rate if patients are properly selected and the surgeon is appropriately trained. A classification system for complications after peripheral nerve surgery and the most common variables associated with failures and complications are presented.

RESUMEN

INTRODUCTION: As peripheral nerve specialists can have a wide variety of training backgrounds, few standards of care exist with respect to necessary incision length, amount of dissection, and operative technique for common nerve decompressions. METHODS: Approaches for the following 12 common peripheral nerve surgeries were minimized using shorter incisions and a simple lighted retractor: zygomatico-temporal and auriculotemporal, greater occipital, brachial plexus, ulnar, radial, median, lateral femoral cutaneous nerve of the thigh, peroneal at the groin, fibular neck and lateral calf, and tibial and inner ankle. The new "minimal" incision length was recorded as was that of the "classical" approach as taught to the senior author and frequently represented in atlases. A Mann-Whiney analysis was independently performed to evaluate for significance between the lengths of incisions for each procedure. RESULTS: The average length of the "minimal" incisions was 3.9 ± 0.6 cm (range, 3.1-6.1 cm), with an average reduction in length of 51% as compared with the "classical" incisions (range, 30-75%; P < 0.001). There were no perioperative morbidities. CONCLUSIONS: Minimally invasive peripheral nerve surgery applied to the above procedures yields successful surgical outcomes while shortening incision lengths and maximizing patient satisfaction without sacrificing patient safety.

RESUMEN

BACKGROUND: In patients with macromastia, the currently accepted indications for reduction mammaplasty are back pain, neck pain, shoulder grooving, and intertrigo in the inframammary fold. Occipital neuralgia and chronic headaches/migraines are not indications, but the authors noted anecdotally that numerous patients with macromastia complained of chronic headaches/migraines, and many of them reported headache improvement following surgery. Therefore, the authors conducted a retrospective review of their cases to evaluate this association. METHODS: A retrospective chart review of all patients undergoing reduction mammaplasty between 2003 and 2008 performed by the senior author (I.D.) was conducted. Patients were followed with clinic visits and telephone interviews. Collected data included preoperative symptoms, pain scores, and postoperative findings. Statistical analysis was conducted using the paired t test. RESULTS: Of the 84 patients who underwent reduction mammaplasty for macromastia between 2003 and 2008, 58 (69 percent) had chronic headaches preoperatively. Of these 58 patients, 31 (53 percent) reported a greater than 50 percent reduction in headache frequency and severity, with 12 (21 percent) stating that their headaches resolved completely after surgery. These patients reported a mean pain score of 7.2 (of 10) before surgery that dropped to 3.2 after reduction mammaplasty. Of all patients, 90 percent reported an improvement in their quality of life. CONCLUSIONS: The authors' data show that patients with macromastia who have occipital neuralgia and/or chronic headaches/migraines can experience headache relief following reduction mammaplasty. Future research should evaluate headaches as indications for reduction mammaplasty. Those patients whose headaches do not improve following breast reduction should consider further specialized evaluation and treatment.

RESUMEN

Patients who present with lower extremity pain following surgery or trauma can occasionally have the saphenous nerve as the offending anatomic cause of their pain. Consistent with its anatomic course, the saphenous nerve can be the source of pain that manifests anywhere along its sensory distribution.Patients who presented to the Georgetown Peripheral Nerve Institute with lower extremity pain were evaluated, and those patients whose pain was suspected to be of saphenous nerve origin were offered surgical treatment. The surgical intervention included excision of the neuroma and/or nerve decompression, as clinically indicated. Patients were followed clinically and evaluated for both their pain as well as recovery in their ambulation and quality of life.Forty-two consecutive patients underwent surgery for pain of saphenous nerve origin from 2003 to 2008; 69% of these patients had concomitant surgery on another involved lower extremity peripheral nerve. Follow-up was achieved in 35 patients (83% response rate), with an average follow-up duration of 34.7 months. Using a 10-point pain scale, patients reported their preoperative pain as an 8.0 and their postoperative pain as a 2.37 (P < 0.001). Of the 35 patients, 30 (86%) were able to ambulate at the last follow-up encounter. Patients were asked to report their quality of life on a 10-point scale, and reported a 77% recovery of their baseline quality of life as a result of peripheral nerve surgery performed. Of the 35 patients, 29 reported that the surgery effectively resolved their pain, yielding a success rate of 82.8%.The saphenous nerve can be a source of lower extremity and knee pain following trauma or surgery. Accurate clinical diagnosis followed by surgical intervention can result in clinical resolution in the majority of patients, with improvement in ambulation and quality of life. This study reports the largest series of surgically-corrected saphenous neuropathy in the literature.

RESUMEN

BACKGROUND: Microvascular free flap techniques have improved over the past two decades such that flap failure rates have dropped to under 3 percent in most large series of high-volume centers. However, despite technical and patient-selection advances, some components of free flap failure might be attributable to undiagnosed patient factors. METHODS: In this clinicopathologic conference article, the authors present four patients with major free flap microvascular complications who were later diagnosed with multiple risk factors for hypercoagulability and biochemical abnormalities, and present the characteristic associated findings. RESULTS: Previously undiagnosed hypercoagulability was present in four patients with major free flap microvascular complications. Hematologic consultation and laboratory investigation revealed the biochemical abnormalities. CONCLUSIONS: In certain patients undergoing microvascular free flap reconstruction, undiagnosed hypercoagulability risk factors can be a source of free flap failure that is independent of patient selection or technical factors. Diagnosis, management, patient counseling, and initiation of deep venous thromboembolism prophylaxis measures are critical clinical components of care of these patients.
