Complications of systemic corticosteroid therapy for problematic hemangioma.

Systemic corticosteroid therapy has been used to treat hemangiomas for 30 years; yet, there are no studies of possible complications. We reviewed the database of the Vascular Anomalies Center at the Boston Children's Hospital and gathered information on short- and long-term side effects in children who were given systemic corticosteroids for problematic hemangiomas. In addition, a questionnaire regarding early and late consequences was sent to the families of children who were treated with corticosteroids from 1983 to 1997. Of 300 patients with hemangiomas, 80 children were identified as having received a full course of systemic corticosteroids for problematic tumors. Complete data were collected on 62 of these children. The response rate to the questionnaire was 78 percent (n = 62 of 80). The initial dose of corticosteroid varied from 2 to 3 mg/kg/ day. Duration of therapy ranged from 2 to 21 months (mean, 7.9 months; median, 6.5 months). The follow-up interval from the cessation of therapy ranged from 6 months to 15 years (mean, 4 years; median, 3 years). Short-term complications included cushingoid facies (n = 44; 71 percent), personality changes (n = 18; 29 percent), gastric irritation (n = 13; 21 percent), fungal (oral or perineal) infection (n = 4; 6 percent), and diminished gain of height (n = 22; 35 percent) and weight (n = 26; 42 percent). A total of 91 percent of children who had diminished gain of height (n = 20) returned to their pretreatment growth curve for height by 24 months of age. One child, who was treated at another institution with a dose of 20 mg/kg/day for 6.5 months that was slowly tapered over 18 months, was petite 6 years after ending therapy. Another child treated with an initial dose of 2 mg/kg/day for 5 months was smaller than predicted at the age of 6 years, but she was born prematurely and was on ventilatory support for respiratory distress. Three children treated with the standard dose and duration were at a low percentile for weight 4, 5, and 10 years after the cessation of therapy. Statistical analysis showed a correlation between diminished gain of height with duration of therapy and age at initiation of treatment. One child had corticosteroid myopathy that resolved with cessation of therapy. We found no evidence for immunologic suppression, i.e., there was no increase in the number of bacterial infections during corticosteroid administration. In conclusion, systemic corticosteroids can be safely given to treat endangering hemangiomas in infants at doses of 2 to 3 mg/kg/day, which are slowly tapered and stopped before the age of 1 year. Short-term side effects were minor and transient, and no serious long-term complications occurred.     

The infected or exposed breast implant: management and treatment strategies

Among the potential complications associated with the use of breast implants are the risks of periprosthetic infection and device extrusion. There is little published information about the effective management of these situations. Conservative recommendations include antibiotic therapy and removal of the implant until resolution of the infection or until the wound has healed. A retrospective review identified patients with periprosthetic infection or threatened or actual device exposure treated by the senior author. Twenty-four patients encompassing 26 affected prostheses were available for review and were classified into seven groups based on initial presentation as follows: group 1, mild infection (n = 8); group 2, severe infection (n = 4); group 3, threatened exposure without infection (n = 3); group 4, threatened exposure with mild infection (n = 3); group 5, threatened exposure with severe infection (n = 1); group 6, actual exposure without clinical infection (n = 5); and group 7, actual exposure with infection (n = 2). To salvage the prosthesis in these patients, various treatment strategies were utilized. All patients with a suspected infection or device exposure were started immediately on appropriate antibiotic therapy (oral antibiotics for mild infections and parenteral antibiotics for severe infections). Salvage methods included one or more of the following: antibiotic therapy, débridement, curettage, pulse lavage, capsulectomy, device exchange, primary closure, and/or flap coverage. Twenty (76.9 percent) of 26 threatened implants with infection or threatened or actual prosthesis exposure were salvaged after aggressive intervention. The presence of severe infection adversely affected the salvage rate in this series. A statistically significant difference exists among those patients without infection or with mild infection only (groups 1, 3, 4, and 6); successful salvage was achieved in 18 (94.7 percent) of 19 patients, whereas only two of seven of those implants with severe infection (groups 2, 5, and 7) were salvaged (p = 0.0017). Ten (90.9 percent) of 11 devices with threatened or actual exposure, not complicated by severe infection (groups 3, 4, and 6), were salvaged. Several treatment strategies were developed for periprosthetic infection and for threatened or actual implant exposure. Patients with infection were placed on oral or intravenous antibiotics; those who responded completely required no further treatment. For persistent mild infection or threatened or actual exposure, operative intervention was required, including some or all of the following steps: implant removal, pocket curettage, partial or total capsulectomy, débridement, site change, placement of a new implant, and/or flap coverage; the menu of options varied with the precise circumstances. No immediate salvage was attempted in five cases, due to either severe infection, nonresponding infection with gross purulence, marginal tissues, or lack of options for healthy tissue coverage. Based on the authors' experience, salvage attempts for periprosthetic infection and prosthesis exposure may be successful, except in cases of overwhelming infection or deficient soft-tissue coverage. Although an attempt at implant salvage may be offered to a patient, device removal and delayed reinsertion will always remain a more conservative and predictable option.     

Phenylketonuria and its variants: observations on intellectual functioning.

The age at diagnosis, dietary treatment and intelligence quotient (IQ) of 119 patients with phenylketonuria (PKU) and its variants who were under long-term observation were studied. In 27 of the 79 patients with classic PKU the diagnosis had been made and treatment begun late (after 2 months of age). The mean IQ of these 27 patients was 57.6 when they were in their early 20s (although 2 had normal IQs). In contrast, among the 52 patients with classic PKU who were not treated late the mean IQ was 93.6 for the 27 who were still receiving dietary therapy. The mean IQs were 99.3 and 92.7 at ages 5 (when the diet was discontinued) and 15 years respectively for the 12 who had been treated "adequately". It was 76.0 for the 13 who were "over-treated" (malnourished) in the first 6 months of life. Among the patients with atypical PKU, who were treated early, the mean IQs were 110.0 for the 7 who were still receiving dietary therapy and 102.7 for the 12 who were not. The 21 patients with persistent benign hyperphenylalaninemia, who were not treated, had a mean IQ of 104.2. The most important factor in the ultimate IQ of patients with classic PKU is very early diagnosis (by 2 weeks of age) along with immediate initiation of dietary therapy.     

Upper extremity limb salvage with microvascular reconstruction in patients with advanced sarcoma

Limb salvage is a viable alternative to amputation in many cases of advanced sarcoma. The authors examined their experience with microvascular reconstruction of upper extremity defects after sarcoma resection, focusing on oncologic and functional outcomes. A retrospective analysis yielded 17 patients who underwent 18 free flap procedures and met the inclusion criteria. Most patients (71 percent, n = 12) had recurrent sarcoma at presentation to the authors' institution. Malignant fibrous histiocytoma was the most common pathologic subtype (n = 6). High-grade tumors were present in 94 percent of patients (n = 16). The free flap survival rate was 100 percent. The rectus abdominis flap was the most common free flap used (39 percent; n = 7). Local recurrence occurred in nine flaps (50 percent), and five patients ultimately required amputations. Six patients (35 percent) had distant recurrence. The mean Enneking score for limb function was 73 percent of the maximum (21.9 of 30). The 5-year disease-specific survival rate was 61.3 percent. In select patients with advanced upper extremity sarcoma undergoing limb salvage, microvascular flap reconstruction can provide reliable, safe coverage with reasonable preservation of function.     

First-line treatment of deep sternal infection by a plastic surgical approach: superior results compared with conventional cardiac surgical orthodoxy

A majority of cardiac surgeons manage deep sternal infection with sternal wound debridement, rewiring, and closed drainage, with or without antibiotic saline tube irrigation (the traditional approach). The authors' experience with the traditional approach was unsatisfactory; therefore, they undertook a radical change in management: an immediate plastic surgical approach. Hence, deep sternal infection was managed by immediate debridement followed by a bilateral pectoralis major myocutaneous advancement flap with greater omental transposition (PMOFR). This is the first such study reporting the effect of this strategy on the rate of eradication of deep sternal infection, intensive care unit stay, total hospital length of stay, major complications, mortality, intermediate survival, and patient satisfaction, as compared with the traditional approach used by cardiac surgeons at the authors' institution.All patients who developed a deep sternal infection from 1993 through 1998 at a tertiary teaching hospital were included. In the PMOFR group (nine patients), after a diagnosis of clinical sternal wound infection, debridement was performed immediately, either if sternal dehiscence occurred or in the absence of clinical dehiscence, if the patient or the sternotomy wound did not clinically improve with medical therapy within 48 hours from suspected diagnosis. Open irrigation and packing for 2 to 4 days was followed by treatment with a PMOFR. In the group treated using the traditional approach (12 patients), no predetermined plan was present. Thus, at the cardiac surgeon's discretion, wound debridement was undertaken, followed by closed drainage (three patients), closed tube irrigation (six patients), and open granulation with delayed plastic surgery (three patients).The incidence of major complications (PMOFR, 22 percent; traditional approach, 92 percent; p = 0.001), intensive care unit readmission (PMOFR, 0 percent; traditional approach, 58 percent; p = 0.005), total hospital length of stay (PMOFR, 32 days; traditional approach, 79 days; p = 0.001), reoperation rates (PMOFR, 0 percent; traditional approach, 100 percent; p = 0.001) and in-hospital 30-day mortality rate (PMOFR, 0 percent; traditional approach, 33 percent; p = 0.05) were superior in the PMOFR group. At a mean follow-up of 2 years, freedom from recurrence of the infection (PMOFR, 100 percent; traditional approach, 11.5 percent; p = 0.005) and overall survival rate (PMOFR, 100 percent; traditional approach, 50 percent; p = 0.005) were also superior with PMOFR. A majority of patients in the PMOFR group (90 percent) had no functional or cosmetic complaints secondary to the procedure.A predetermined plan of immediate debridement followed by treatment with PMOFR rapidly, reliably, and effectively eradicated deep sternal infection. This translated to reduced length of stay and need for additional surgery, improved survival, and excellent intermediate freedom from deep sternal infection, with minimal patient dissatisfaction. The traditional approach to managing deep sternal infection was thus abandoned.     

An outcome evaluation of sphincter pharyngoplasty for the management of velopharyngeal insufficiency

Sphincter pharyngoplasty is frequently used for the management of children with velopharyngeal insufficiency. The purpose of this study was to evaluate outcome and revision rates of sphincter pharyngoplasty at the authors' institution. Two hundred fifty patients underwent sphincter pharyngoplasty for velopharyngeal insufficiency between January of 1987 and March of 2001. There were 117 female patients and 133 male patients, with a mean age at primary sphincter pharyngoplasty of 7.6 years (range, 1 to 45 years). Diagnoses included velopharyngeal insufficiency alone (n = 63), velopharyngeal insufficiency associated with cleft palate (n = 127), velocardiofacial syndrome (n = 32), submucous cleft (n = 15), and other (n = 13). Pharyngoplasty revision was defined as any secondary surgical revision of the sphincter as determined by clinical evaluation and objective speech assessment. The pharyngoplasty revision rate was found to be 12.8 percent (n = 32). A favorable outcome was demonstrated in 30 of these patients (93.8 percent) after pharyngoplasty revision. Two patients, one with a diagnosis of a submucous cleft and velocardiofacial syndrome and the other with a cleft palate, required a second revision because of persistent velopharyngeal insufficiency. The revision rate was highest in those patients with velocardiofacial syndrome (21.8 percent) and lowest in patients with velopharyngeal insufficiency alone (6.3 percent). Patients who required revision had significantly higher preoperative oral sentence nasometry (55.2 percent versus 46.1 percent; p < 0.01) and larger velopharyngeal areas (23.7 mm2 versus 18.9 mm2). There was no significant difference in age or sex for those patients who required a revision compared with those who did not require revision. Mean follow-up was 2.4 years (range, 4 months to 13.6 years). Sphincter pharyngoplasty is an effective procedure for the treatment of velopharyngeal insufficiency using revision rate as the standard of success. It had an 87 percent primary success rate that increased to 99 percent after a single revision. Patients with velocardiofacial syndrome, more severe preoperative hypernasal resonance, and larger velopharyngeal areas were more likely to require pharyngoplasty revision.     

Skin-sparing mastectomy and immediate autologous tissue reconstruction after whole-breast irradiation

Traditional breast conservation therapy consists of lumpectomy and whole-breast irradiation. Local recurrence after breast conservation is usually managed with salvage mastectomy. Skin-sparing mastectomy and immediate autologous tissue reconstruction is an accepted method of managing primary breast malignancies with exceptional aesthetic results. The purpose of this study was to evaluate this technique in the previously irradiated breast. This study is a retrospective review of all patients undergoing skin-sparing mastectomy and immediate reconstruction with autologous tissue after failed breast conservation therapy between 1995 and 1999. There were 11 patients with a mean age of 45 years (range, 34 to 58 years). Initial lumpectomy was performed for ductal carcinoma in situ in six patients and infiltrating carcinoma (ductal or lobular) in five patients. The interval from lumpectomy to salvage mastectomy ranged from 12 to 169 months (mean, 44 months). Reconstructive techniques included unipedicled transverse rectus abdominis musculocutaneous (TRAM) flap (n = 4), free TRAM flap (n = 4), and latissimus flap with immediate placement of a saline implant (n = 3). Flap survival was 100 percent, and there were no early flap complications. One patient developed partial-thickness mastectomy flap loss (3 x 3 cm), which was managed conservatively. There were no instances of full-thickness mastectomy skin loss. Late complications included capsular contracture (n = 2), fat necrosis (n = 1), and ventral hernia (n = 1). There was one late death from metastatic disease; the remaining patients were without evidence of disease at a mean of 48 months (range, 30 to 75 months). Aesthetic results were judged as excellent (n = 4), good (n = 5), fair (n = 1), and poor (n = 1). These results demonstrate that skin-sparing mastectomy and immediate autologous tissue reconstruction can be safely performed in patients with previous whole-breast irradiation. Clearly, patient selection is paramount with attention to the quality of the irradiated breast skin and the anatomic location of the recurrent disease. In this experience, the best results were seen after TRAM (pedicled or free) flap reconstruction.     

Treatment of keloids by surgical excision and immediate postoperative single-fraction radiotherapy

The authors report the outcomes of patients with keloid scars treated with a protocol of extralesional excision and immediate single-fraction adjuvant radiotherapy. The design of the study was a retrospective analysis with up to 5-year outcome data. The setting was a single treatment team, University Teaching Hospital in London, United Kingdom. Participants (n = 80) were treated for 80 keloid scars (59 percent female patients, 76 percent nonwhite), and 44 percent of keloids were located on earlobes. For all patients, prior treatment without radiotherapy had failed. The salvage treatment reported in this article is combined extralesional excision and immediate postoperative external-beam radiotherapy. A 10-Gy dose of superficial 60-kV or 100-kV photon irradiation was given within 24 hours of the operation. The main outcome measure was freedom from recurrence of keloid scars. Results were that all keloid scars were controlled at 4-week follow-up. Probability of relapse at 1 year was 9 percent; at 5 years, probability of relapse was 16 percent. The earlobe showed no greater chance of relapse than other sites on the body. The authors' report shows that extralesional excision of keloid followed by early, single-fraction, postoperative radiotherapy is both simple and effective in preventing recurrence at excision sites.     

The course of diagnosis in autistic patients: the delay between recognition of the first symptoms by parents and correct diagnosis

The primary aim of the research was to find the delay between the first symptoms of an autistic disorder being recognized by parents and diagnosis in our centre. A secondary objective was to evaluate the number of contacts with professionals (physicians, teachers, and speech therapists) in which parents pointed out special manifestations seen in children and, in spite of that, the children were not referred to a specialist. A retrospective study assessed 204 children (59 girls, 145 boys) in total; 126 children (39 girls, 87 boys) with childhood autism (CHA), 57 (17 girls, 40 boys) with atypical autism (AA), and 21 (3 girls, 18 boys) with Asperger's syndrome (AS). The mean age at appearance of the first signs was 29.7 months (range 0-70, median 30+/-17.0) in N=201, and the average age at diagnosis was 81.5 months (range 13-276, median 69.5+/-45.2) in N=204. The mean delay in making a diagnosis was 51.3 months (range 0-246, median 39+/-40.9) in N=201. The delay in diagnosis is shortest in patients with AA (a mean period of 44.4 months = 3 years and 8 months), longer in CHA patients (49.5 months = 4 years and 2 months), and longest in patients with AS (80.8 months = 6 years and 9 months). A statistically significant difference in the period to diagnosis was found between CHA and AS patients (p=0.023) and between AA and AS patients (p=0.019). The mean number of visits to physicians and other specialists before referring to a specialized centre for diagnosis in N=133 was 2.4 (range 1-5, median 2+/-0.9). The diagnosis of autism is made late and early educational and behavioural interventions cannot be initiated.     

Dynamic versus static splinting of simple zone V and zone VI extensor tendon repairs: a prospective, randomized, controlled study

The authors present the first prospective, randomized, controlled study comparing postoperative dynamic versus static splinting outcomes of patients following extensor tendon repair. Patients who incurred simple and complete lacerations of their extensor tendons in zones V and VI were enrolled into the study and underwent either static splinting (n = 17) or dynamic splinting (n = 17) following primary acute repair of tendons. Total active motion was improved in the dynamic group when compared with the static group in the injured digits at 4 weeks (180.5 +/- 4 degrees versus 131.3 +/- 61 degrees; p = 0.006), at 6 weeks (239 +/- 21.9 degrees versus 205.5 +/- 53.4 degrees; p = 0.048), and at 8 weeks (247+/- 19.8 degrees versus 216.3 +/- 36 degrees; p = 0.051), but not at 6 months (253.1 +/-18.8 degrees versus 250.5 +/- 32 degrees; p = 0.562). Similarly, total active motion averaged for all digits (injured and noninjured) of the involved hand was improved in the dynamic group over the static group at 4 weeks (209.8 +/- 31.3 degrees versus 140 +/- 58.2 degrees; p < 0.001) and at 6 weeks (241.5 +/- 17.2 degrees versus 217.1 +/- 42.4 degrees; p = 0.024), but not at 8 weeks (249.6 +/- 16 degrees versus 234.8 +/- 24.5 degrees; p = 0.215) or 6 months (252.3 +/- 14 degrees versus 249.1 +/- 31 degrees; p = 0.450). Grip strength outcomes demonstrated improved grip force for the dynamic group when compared with the static group at 8 weeks (81.3 +/- 18.0 percent versus 59.2 +/- 20.4 percent; p = 0.004) but not at 6 months (89.6 +/- 5.6 percent versus 82.1 +/- 22.0 percent; p = 0.595). Patients demonstrated forceful grip greater than or equal to 80 percent of the noninjured hand in 55 percent of patients in the dynamic group versus 15 percent of patients in the static group at 8 weeks. Patients demonstrated forceful grip greater than or equal to 80 percent of the noninjured hand in 100 percent of patients in the dynamic group versus 73 percent of patients in the static group at 6 months. The authors' findings suggest that dynamic splinting of simple, complete lacerations of the extensor tendons in zones V and VI provides improved functional outcomes at 4, 6, and 8 weeks but not by 6 months when compared with static splinting. Therefore, they recommend dynamic splinting of simple, complete extensor tendon lacerations in zones V and VI only to select patients who are motivated and desire earlier return to full functional capacity.     

Clinical management of patients with invasive cervical cancer following a negative Pap smear

Among 535 patients with invasive cervical carcinoma seen between January 1975 and June 1986, 26 were found to have developed the disease within six months (65 percent), 35 within 12 months (88 percent), 37 within 13 months (93 percent), and three developed the disease within 17 months after a negative Pap smear. Eighty-eight percent of these 40 patients were under age 40 at diagnosis. Rapidly progressive cancers are highly resistant to radiation therapy. Seven stage IB patients treated only with radiation died within nine to 29 months after initial therapy. By contrast, 15 patients treated by radical hysterectomy and four by radical hysterectomy and post-surgical radiation were alive with no evidence of disease from six to 109 months after surgery (median, 30 months). Six of nine patients with stage II to IV disease treated with radiation have died; the remaining three are alive. One patient is well 14 months after therapy, but two others have developed metastases seven and 12 months after treatment. Surprisingly, 37 of 40 patients had symptoms of pain, bleeding, and discharge at the initial diagnosis, but their physicians had a false sense of security because of a recent negative Pap smear. Early biopsy diagnosis and radical hysterectomy with bilateral pelvic lymphadenectomy is the most effective management for this cancer.     

Complications after reconstruction by plate and soft-tissue free flap in composite mandibular defects and secondary salvage reconstruction with osteocutaneous flap

Reconstruction of composite defects of the mandible is a challenging problem. Although the use of an osteocutaneous free flap, alone or in combination with another soft-tissue free flap, is generally accepted to be optimal, the bony reconstruction is sometimes undervalued, especially when the cancer is advanced. In such situations, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap. Between January of 1997 and July of 2000, 80 patients with composite or extensive composite oromandibular defects underwent treatment with a reconstruction plate and a soft-tissue free flap. All of the patients were male, and the ages of the patients at the time of treatment ranged from 32 to 78 years (mean, 51 years). Tumors were classified as stage IV in 56 patients (70 percent), whereas the remaining 24 patients (30 percent) had recurrent carcinomas. The titanium mandibular reconstruction system manufactured by Stryker (Freiburg, Germany) was used to bridge the mandibular defects. The soft-tissue free flaps used for wound and plate coverage were as follows: anterolateral thigh flap (n = 75), radial forearm flap (n = 3), transverse rectus abdominis myocutaneous flap (n = 1), and tensor fasciae latae flap (n = 1). Five patients with recurrent carcinomas and 10 with stage IV carcinomas (18.75 percent) died 2 to 6 months after the operation and were excluded from the study. The remaining 65 patients were monitored for an average follow-up period of 22 months (range, 6 to 40 months). During that period, one or more complications occurred for 45 patients (69.2 percent). Plate exposure was the most common complication and was observed for 30 patients (46.15 percent). Twenty of the 65 patients (30.8 percent) required secondary salvage reconstruction with a fibula osteoseptocutaneous flap. The decision to perform a secondary salvage procedure was based on the general health of the patient, the extent of local disease, and the severity of the complications. Patients underwent salvage operations after an average of 11.5 months (range, 6 to 26 months). The major reasons for the second operation were as follows: reconstruction plate exposure (n = 12), soft-tissue deficiency and mandibular contour deformation of the lateral face (n = 7), intraoral contracture and lack of a gingivobuccal sulcus (n = 6), trismus (n = 4), and osteoradionecrosis of the mandible (n = 2). The total flap survival rate was 90 percent (18 of 20 free flaps). In two cases, the skin paddles of the fibula osteoseptocutaneous flaps exhibited partial failure and were revised with pedicled pectoralis major and deltopectoral flaps. The reconstruction plate and free soft-tissue flap procedure for the reconstruction of composite defects of the oromandibular region has many late complications, which eventually necessitate reconstruction of the mandible with an osteocutaneous free flap.     

Facial skeletal reconstruction using porous polyethylene implants

A retrospective review of clinical outcomes was performed to determine the clinical utility and morbidity associated with the use of porous polyethylene facial implants. Three hundred seventy implants were placed in 162 consecutive patients, in 178 operations performed in 11 years. The number of patients, the number of implants used, and the average follow-up period were categorized according to the cause of the deformity. The resultant distribution was as follows: acquired (tumor-related), 17 patients, 39 implants, and 30 months; congenital, eight patients, 31 implants, and 92 months; aesthetic, 39 patients, 97 implants, and 24 months; secondary posttraumatic, 48 patients, 139 implants, and 37 months; and acute trauma (internal orbit reconstruction), 50 patients, 64 implants, and 9 months. The distribution of implants according to location was as follows: frontal, 21; temporal, 30; internal orbit, 145; infraorbital rim, 28; malar, 58; paranasal, 29; nasal, 13; mandible, 24; and chin, 22. The combined average follow-up period per patient was 27 months (range, immediate postoperative period to 11 years). All implants were placed in the subperiosteal plane, and the majority were fixed with titanium screws. Antibiotics were administered perioperatively. No implants were extruded or migrated, formed clinically apparent capsules, or caused symptoms attributable to bioincompatibility. The overall reoperation rate was 10 percent (n = 16), which included operations to remove implants because of acute infections (2 percent, n = 3) or a late infection (1 percent, n = 1), to remove implants causing displeasing contours (2 percent, n = 3), and to improve contours (6 percent, n = 9). Porous polyethylene implants have biomaterial properties favorable for facial skeletal augmentation. Screw application of the implants to the skeleton allows precise predictable contouring, thus limiting the need for revisional surgical procedures.     

Clinical outcomes in lymphocytopenic lymphatic malformation patients

BACKGROUND: To determine if lymphocytopenia in patients with lymphatic malformation (LM) is associated with rates of infection and poor clinical outcomes. MATERIALS AND METHODS: This is a retrospective case series at a tertiary pediatric hospital, of 21 consecutive patients (11 male and 10 female) undergoing LM treatment. Clinical data (i.e., age, clinical LM stage, presence of tissue hypertrophy, frequency/type of medical therapy, and number of hospitalizations) obtained from LM patients with lymphocytopenia (n = 6) was compared to LM patients without lymphocytopenia (n = 15). RESULTS: The average age at the time of detailed leukocyte analysis was 67 months (Range 1-231). Six patients with lymphocytopenia (below 1500/cm(3)) were compared with 15 without lymphocytopenia (above 1500/cm(3)). All six patients with lymphocytopenia had large bilateral LM and normal neutrophil and platelet counts. The total number of hospital admissions was two times greater in lymphocytopenic patients (mean 8.3) compared to nonlymphocytopenic patients (mean 4.09) Chi square analysis revealed a statistical difference in lymphocytopenic patients. They were more likely to have had central line placement, central line infection, bacteremia, prophylactic antibiotics, admission at birth, infections distant from the lymphatic malformation and a treatment complication compared to nonlymphocytopenic patients. Univariate logistic regression revealed that, independent of LM stage, the use of prophylactic antibiotics, the need for a central line, the occurrence of a line infection, and the hospital admission rate were significantly increased in lymphocytopenic patients. CONCLUSION: Patients with LM-associated lymphocytopenia have increased hospitalization requirements, rate of infection, and receive more intensive antibiotic therapy compared to nonlymphocytopenic LM patients.     

Surgical treatment of infective endocarditis with special reference to prosthetic valve endocarditis.

Patients with native valve endocarditis treated surgically between 1968 and 1978 (n = 15) and all patients presenting with prosthetic valve endocarditis during this period (n = 21) were followed up for at least four years. Five of the patients with native valve endocarditis required urgent early surgical intervention, of whom two died. The remaining 10 underwent valve replacement after a course of antibiotic treatment: all survived, though one required further valve replacement. The 21 patients with prosthetic valve endocarditis suffered 25 attacks. Nine were cured by medical treatment alone; two died before surgical intervention was possible; 11 required valve replacement, of whom three died; and two required valve replacement after a course of antibiotic treatment. The incidence of early prosthetic valve endocarditis--that occurring within two months of operation--was 0.67%, but that of late prosthetic valve endocarditis could not be determined. Medical treatment when started early should cure endocarditis in most patients, but vigilance should be maintained for the appearance of indications for surgery. When such indications exist surgery should not be delayed.     

Mycobacterium marinum infections in humans and tracing of its possible environmental sources

The low frequency of nontuberculous mycobacterial infections, nonspecific symptoms for individual mycobacteria, and the lack of specific identification methods could alter correct diagnosis. This study presents a combined microbiology and molecular-based approach for Mycobacterium?marinum detection in four aquarists with cutaneous mycobacterial infection. Simultaneously, ecology screening for M.?marinum presence in the aquarists' fish tanks was performed. A total of 38 mycobacterial isolates originated from four human patients (n?=?20), aquarium animals (n?=?8), and an aquarium environment (n?= 10). Isolate identification was carried out using 16S?rRNA sequence analysis. A microbiology-based approach, followed by 16S rRNA sequence analysis, was successfully used for detection of M.?marinum in all four patients. Animal and environmental samples were simultaneously examined, and a total of seven mycobacterial species were isolated: Mycobacterium chelonae , Mycobacterium fortuitum , Mycobacterium gordonae , Mycobacterium?kansasii , Mycobacterium mantenii , Mycobacterium marinum , and Mycobacterium?peregrinum . The presence of M.?marinum was proven in the aquarium environments of two patients. Although M.?marinum is described as being present in water, it was detected only in fish.     

A study of replacement of timolol-pilocarpine with latanoprost in pseudoexfoliation glaucoma

The aim of the study was to evaluate the efficacy of replacing current dual local therapy (timolol and pilocarpine) with latanoprost 0.005% in 71 pseudoexfoliation glaucoma patients with controlled intraocular pressure (IOP). 39 patients switched to latanoprost 0.005%) and 32 patients continued timolol-pilocarpine therapy. Mean diurnal (IOP) was measured at baseline, after 0.5, 1, 3 and 6 months of treatment. After 6 months 38 patients with latanoprost and 30 patients with timolol-pilocarpine had completed the study. At baseline the mean diurnal IOP was 20.4 +/- 2.0 mmHg for patients in latanoprost treatment group and 21.4 +/- 2.1 mmHg for patients in timolol-pilocarpine group. At the end of the study, after 6 months of treatment, the mean diurnal IOP values were 16.6 +/- 2.4 and 17.9 +/- 2.0 mmHg respectively. IOP was statistically significantly reduced from baseline (p < 0.001). The mean diurnal IOP change from baseline was -3.3 +/- 0.5 mmHg (mean +/- SEM, ANCOVA) for the patients treated with latanoprost and -3.2 +/- 0.4 mmHg for the patients treated with timolol + pilocarpine. This difference in IOP reduction between groups was not statistically significant (z = 0.69; p = 0.49). This study showed that combination therapy (timolol plus pilocarpine) in pseudoexfoliation glaucoma can effectively be replaced by latanoprost monotherapy.     

Early microsurgical reconstruction of complex trauma of the extremities

Five hundred and thirty-two patients underwent microsurgical reconstruction following trauma to their extremities. They were divided into three groups for the purpose of review. Group 1 underwent free-flap transfer within 72 hours of the injury, group 2 between 72 hours and 3 months of the injury, and group 3 between 3 months and 12.6 years, with a mean of 3.4 years. The results were analyzed with respect to flap failure, infection, bone-healing time, length of hospital stay, and number of operative procedures. The flap failure rate was 0.75 percent in group 1, 12 percent in group 2, and 9.5 percent in group 3 (p less than 0.0005 early versus delayed; p less than 0.0025 early versus late). Postoperative infection occurred in 1.5 percent of group 1, 17.5 percent of group 2, and 6 percent of group 3. Bone-healing time was 6.8 months in group 1, 12.3 months in group 2, and 29 months in group 3. The average length of total hospital stay was 27 days for group 1, 130 days for group 2, and 256 days for group 3. The number of operations averaged 1.3 for group 1, 4.1 for group 2, and 7.8 for group 3.     

Diagnosis delay in Libyan female breast cancer

ABSTRACT: BACKGROUND: To study the diagnosis delay and its impact on stage of disease among women with breast cancer on Libya METHODS: 200 women, aged 22 to 75 years with breast cancer diagnosed during 2008--2009 were interviewed about the period from the first symptoms to the final histological diagnosis of breast cancer. This period (diagnosis time) was categorized into 3 periods: <3 months, 3--6 months, and >6 months. If diagnosis time was longer than 3 months, the diagnosis was considered delayed (diagnosis delay). Consultation time was the time taken to visit the general practitioner after the first symptoms. Retrospective preclinical and clinical data were collected on a form (questionnaire) during an interview with each patient and from medical records. RESULTS: The median of diagnosis time was 7.5 months. Only 30.0% of patients were diagnosed within 3 months after symptoms. 14% of patients were diagnosed within 3--6 months and 56% within a period longer than 6 months. A number of factors predicted diagnosis delay: Symptoms were not considered serious in 27% of patients. Alternative therapy (therapy not associated with cancer) was applied in 13.0% of the patients. Fear and shame prevented the visit to the doctor in 10% and 4.5% of patients, respectively. Inappropriate reassurance that the lump was benign was an important reason for prolongation of the diagnosis time. Diagnosis delay was associated with initial breast symptom(s) that did not include a lump (p < 0.0001), with women who did not report monthly self examination (p < 0.0001), with old age (p = 0.004), with illiteracy (p = 0.009), with history of benign fibrocystic disease (p = 0.029) and with women who had used oral contraceptive pills longer than 5 years (p = 0.043). At the time of diagnosis, the clinical stage distribution was as follows: 9.0% stage I, 25.5% stage II, 54.0% stage III and 11.5% stage IV.Diagnosis delay was associated with bigger tumour size (p <0.0001), with positive lymph nodes (N2, N3; p < 0.0001), with high incidence of late clinical stages (p < 0.0001), and with metastatic disease (p < 0.0001). CONCLUSIONS: Diagnosis delay is very serious problem in Libya. Diagnosis delay was associated with complex interactions between several factors and with advanced stages. There is a need for improving breast cancer awareness and training of general practitioners to reduce breast cancer mortality by promoting early detection. The treatment guidelines should pay more attention to the early phases of breast cancer. Especially, guidelines for good practices in managing detectable of tumors are necessary.     

Analysis of pharyngocutaneous fistula following free jejunal transfer for total laryngopharyngectomy

The development of a pharyngocutaneous fistula is the most common and troublesome complication in the early postoperative period following free jejunal transfer for total laryngopharyngectomy. However, many aspects of this complication remain unclear. In this study, the authors analyzed their experience with the pharyngocutaneous fistula formation following free jejunal transfers to evaluate its clinical behavior, determine the significance of the anastomotic technique used, and evaluate the role of preoperative radiation therapy on its formation and management. Of 168 patients who underwent free jejunal transfers following total laryngopharyngectomy at the authors' institution between July of 1988 and March of 2000, 23 patients (13.7 percent) with postoperative fistulas were identified. The mean onset of fistula formation was 16 days. Of the 23 fistulas, 13 (56.5 percent) occurred at the proximal and 10 (43.5 percent) at the distal anastomoses. Whereas the majority of the proximal fistulas (69.2 percent) developed near the mesenteric side of the jejunal flap, most of the distal fistulas (90 percent) were located anteriorly. The incidence of proximal fistula formation was higher in patients with a single-layer repair than in patients with a two-layer repair of a proximal anastomosis (80 percent versus 38.5 percent, p = 0.09). The incidence of fistula formation was greater in patients who received preoperative radiation therapy than in those who did not (16.3 percent versus 11.4 percent, p = 0.36). In addition, whereas a majority of fistulas (80 percent) occurred at the proximal anastomosis in patients who did not receive preoperative radiation therapy, most fistulas (61.5 percent) occurred at the distal anastomosis in patients who did receive radiation therapy (p = 0.09). The fistulas closed spontaneously in 15 patients (65 percent). On average, spontaneous closure occurred in 7.4 weeks. Proximal fistulas had a significantly higher rate of spontaneous closure compared with distal fistulas (85 percent versus 40 percent, p = 0.04). The rate of spontaneous fistula closure was higher in patients who had not received preoperative radiation therapy than in those who had (90 percent versus 46 percent, p = 0.07). Surgical closure of the fistula was required in five patients. The fistulas were not repaired in three patients because of recurrent tumor. Twenty patients (87 percent) resumed oral feeding after the closure of the fistula, with 17 (85 percent) of 20 patients tolerating a regular diet and three (15 percent) of 20 a liquid diet only.In conclusion, most fistulas occur at the proximal anastomosis and near the mesenteric side of the jejunal flap, and the use of a two-layer anastomotic technique seems to be associated with a lower incidence of fistula formation at the proximal suture line. Most fistulas close spontaneously, especially ones that occur proximally. Preoperative radiotherapy does seem to increase the risk of fistula formation, especially at the distal anastomotic site and make subsequent resolution of the fistulas more difficult. Most patients are able to resume oral feeding once the fistula is closed.
