Biliary cystadenoma: rare variant of intrahepatic cystic disease.

Intrahepatic nonparasitic cystic disease is rare and may be of congenital or neoplastic origin. The most frequent symptoms and signs are nonspecific and include pain, nausea, fullness, increased girth, and palpable mass. Interventional therapy is reserved for symptomatic patients, which usually corresponds to cysts >5 cm in diameter. Retrospective analysis revealed 26 cases of intrahepatic cystic disease over 15 years at our institution. We discuss the case of a patient who had bilobular biliary cystadenomatous disease, a rare, benign variant of intrahepatic nonparasitic cystic disease.

Urinary stress incontinence among obese women: review of pathophysiology therapy.

Obesity is a common condition among women in developed countries and has a major impact on stress urinary incontinence. Women suffering from obesity manifest increased intra-abdominal pressures, which adversely stress the pelvic floor and may contribute to the development of urinary incontinence. In addition, obesity may affect the neuromuscular function of the genitourinary tract, thereby also contributing to incontinence. Accordingly, thorough evaluation of obese women must be performed prior to the institution of treatment. Weight loss may relieve urinary incontinence, but definitive therapy via operative procedures is effective even in obese patients and should be recommended with confidence.

Renal inflammatory pseudotumor.

A previously healthy 37-year-old man had evaluation of abdominal pain, which had persisted after abrupt onset with fever and hematuria. Although the fever and hematuria had spontaneously resolved after 1 week, the abdominal pain had worsened over a 4-month period. Predicated upon computed tomography and with a presumed diagnosis of renal cell adenocarcinoma, left radical nephrectomy was done. Histopathologic analysis was negative for malignancy but compatible with inflammatory pseudotumor of the urogenital tract--a pathologic entity that is common in the urinary bladder and prostate gland but is rarely diagnosed in the kidney.

Explantation of silicone breast implants.

Silicone gel-filled breast implants have been employed clinically for decades for aesthetic augmentation or postmastectomy reconstruction. Most patients and surgeons attest to the efficacy and safety of these devices. However, more recently in the medical literature and popular media, silicone gel-filled breast implants have been claimed to incite an array of clinical sequelae such as capsular formation, granulomatous disease, arthritis, arthralgia, fibromyalgia, autoimmune collagen vascular disease, human adjuvant disease, siliconosis, silicone-related disease, and silicone implant-associated syndrome. During a recent 24-month period, 25 referred patients underwent explantation of bilateral silicone gel-filled prostheses at the University of South Alabama. Patient-reported symptoms and signs included mastodynia, arthralgia, fibromyalgia, xerophthalmia, xerostomia, hypesthesia, and amblyopia. Clinical examination and mammography were reliable in diagnosing implant rupture, but only re-exploration reliably detected implant leakage. Most patients underwent concurrent replacement with saline-filled devices. Histopathologic analyses of all tissue samples revealed chronic inflammation. Subjective improvement of patient-reported symptoms and signs occurred over the course of months postoperatively. There was no mortality associated with explantation, with or without replacement, but an overall morbidity incidence of 20 per cent (5 of 25) was observed. Predicated upon review of the available scientific literature and analysis of this modest number of patients, the following perspectives are germane. 1) A small cohort of patients of status postimplantation of silicone gel-filled devices will manifest chronic morbidity. Identifying such patients prospectively remains problematic. 2) Whether or not silicone gel incites adverse systemic phenomena is unproven, although it has been implicated. 3) Symptomatic patients with silicone gel-filled implants in place should be considered for removal, with full knowledge of the morbidity associated with revisional procedures. 4) Patients currently undergoing breast augmentation or reconstruction employing prosthetics are perhaps best served by insertion of saline-filled devices. 5) Patient-physician dialogue regarding the risk-benefit analysis of prosthetic implantation is imperative. Patients consenting to such procedures must be willing to assume risks.

Myocardial bridging prevents safe laparoscopy? A case report.

A 49-year-old male presented with atypical chest pain. Complete cardiac evaluation was normal except for cardiac catheterization, which revealed a myocardial bridge across the LAD (left anterior descending coronary artery) that caused a 50% systolic stenosis. Abdominal ultrasound revealed cholelithiasis. The patient became asymptomatic and was discharged only to return with biliary pancreatitis, which resolved over 2 weeks and laparoscopic cholecystectomy was attempted. Upon establishment of a pneumoperitoneum, he began to suffer cardiac ischemia, which immediately resolved upon desufflation. The procedure was converted to an uneventful open cholecystectomy. He did well without any further problems. This is the first report of myocardial bridging, a well-known cardiac anomaly, possibly preventing safe laparoscopy. This was possibly due to transmitted intraperitoneal pressure effect on the pericardium pushing closed that myocardial bridge.

Hand injuries secondary to subcutaneous illicit drug injections.

We present a retrospective analysis of 32 patients admitted over a 5-year period to a metropolitan regional trauma center with recently induced subcutaneous ("skin pop") illicit drug injectional injuries involving the hand. Cocaine derivatives were the most frequently reported illicit drug used (75%). All patients had local disease manifested by subcutaneous abscess formation, and several had regional disease (cellulitis, lymphangitis, or lymphadenopathy), but only one patient had systemic illness. Microbiological analysis revealed endogenous integumentary and oral flora sensitive to oral preparations of several antibiotic medications including cephalosporins. Primary therapy included intravenous administration of antibiotic medications in all instances and simple incision and drainage under local anesthesia in 26 patients (81%). Six patients (19%) required more radical operative therapy. All patients were hospitalized and recovered without sequelae, with preservation of hand function after follow-up evaluation, which ranged from weeks to months, except for 1 patient who required digital amputation because of necrosis. Although the issue of compliance in terms of wound and general medical care for this patient population is problematic, analysis of the data suggested that patients with illicit drug injectional injuries of the hand confined to subcutaneous regions could be effectively and safely managed in outpatient settings by simple wound care and orally administered cephalosporin medications.

Hemicorporectomy.

Intractable decubitus ulcers and femoropelvic osteomyelitis are rare sequelae of paraplegia. Therapy for these conditions ranges from the simple to the complex, including wound debridement and care, alimentary and urinary tract diversion, hip disarticulation, and myofasciocutaneous rotational flaps. Should the condition be recalcitrant to these modalities the only curative therapy is hemicorporectomy. A 28-year-old rendered paraplegic 3 years ago presented manifesting sepsis; marasmus; hip and knee flexion contractures; suppurative sacral and femoropelvic decubitus ulcers, exposed bone, and osteomyelitis; and fecal and urinary incontinence. Pre-operative nutritional supplementation, wound debridement and care, and psychological counselling were provided. Hemicorporectomy was performed, including colostomy, ureteroileal conduit, gastrostomy, and translumbar amputation. Several anatomical, physiological, and operative-technical perspectives are emphasized: a two-staged approach may be preferable--at the first setting an intra-peritoneal exploratory celiotomy with alimentary and urinary tract diversion; and at the second setting an extra-peritoneal hemicorporectomy; preservation of abdominal wall musculature and fasciae to facilitate wound closure; sequential and bilateral ligation of the arteriae et venae iliaca communis; translumbar amputation between the fourth and fifth lumbar vertebrae; extirpation of the fourth lumbar processus spinosus vertebrarum; closure of the dura mater and translation of musculi sacrospinalis into the vertebral canal; avoidance of hypervolemia and hyperthermia; avoidance of wound pressure; testosterone replacement therapy for eunuchism; and physical and occupational rehabilitation including adaptation to a customized bucket prosthesis.

Management of exposed inguinofemoral arterial conduits by skeletal muscular rotational flaps.

Peripheral vascular reconstructions are common operations for the treatment of occlusive atherosclerosis, and the vast majority are uncomplicated. However, despite all precautionary measures, a small percentage of patients will manifest wound infection and graft exposure that may evolve to loss of limb and/or life. Treatment has traditionally consisted of systemic administration of antibiotic medication(s), graft extirpation, and extra-anatomic arterial bypass; yet despite use of these more radical modalities, morbidity and mortality have remained high. An additional meritorious adjunct for the treatment of exposed prosthetic or autogenous saphenous vein arterial bypass grafts is the use of local/regional autogenous skeletal muscular rotational flaps. Reported herein are the results of this technique applied to the inguinofemoral regions of eight patients. Rectus abdominis (1 patient), rectus femoris (4), and sartorius (4) skeletal muscular rotational flaps were employed. Seven of eight (88%) patients convalesced well at mean duration of follow-up measuring 24 months, although one patient subsequently required major amputation due to progression of occlusive atherosclerosis. One of eight (12%) patients succumbed secondary to irreversible sepsis, despite radical amputation. The data suggest that use of local/regional skeletal muscular rotational flaps is a useful adjunct for the treatment of patients with exposed arterial conduits.

Fabricated single lumen tracheal cannula for a morbidly obese patient.

Morbidly obese patients who manifest upper airway obstruction or pulmonary insufficiency may require tracheostomy to ensure patency or provide ventilatory support, respectively. In this patient population the girth of the neck region may preclude use of currently available manufactured standardized tracheostomy tubes. Reported herein is the fabrication of a tracheal cannula with bisociation of an uncuffed endotracheal tube and the "swivel neck plate" of a tracheostomy tube, to provide a secure and comfortable single lumen tracheal prosthesis to accommodate such a patient's unique anatomy. The technique is applicable to other clinical scenarios if standard marketed tracheostomy tubes do not suffice.

Tumor necrosis factor-induced mortality is reversed with cyclooxygenase inhibition.

OBJECTIVE: The authors hypothesized that TNF would induce eicosanoid synthesis, and a cyclooxygenase inhibitor would attenuate both eicosanoid synthesis and improve survival in an LD90 TNF-induced (150 ng/kg/i.v./5 min) mortality model. SUMMARY BACKGROUND DATA: Tumor necrosis factor is a cardinal mediator in sepsis; however, little is known about its effects on arachidonate metabolism. METHODS: Conscious male rats with carotid arterial and jugular venous catheters were randomized for mortality: group I, TNF alone (150 kg/i.v./15 min, n = 30); group II, ibuprofen (30 mg/kg/i.v. at t = -20 and +240 min), plus TNF, (n = 28); and for hemodynamics, eicosanoid synthesis, blood gases: group III, TNF alone, (n = 8); group IV, ibuprofen + TNF (n = 8); group V, monoclonal antibody to TNF plus TNF (n = 8). Mortality was determined at 4-72 hr. Other parameters determined over 4 hours (0, 5, 60, 120, 240 min). RESULTS: TNF stimulated synthesis of (a) TXB2 (71 +/- 30 pg/ml, mean +/- SE at base vs. 117 +/- 18 at 4 hr, p < 0.02); (b) PGE2 (70 +/- 6 pg/ml at base vs. 231 +/- 68 at 4 hr, p < 0.02); (c) 6PGF (52 +/- 6 pg/ml at base vs. 250 +/- 80 at 4 hr, p < 0.02). Ibuprofen significantly (p < 0.05) inhibited eicosanoid synthesis from TNF. TNF-induced mortality (87%, 26/30) was dramatically decreased with ibuprofen (11%, 3/28), at 4, 24, and 72 hr (p < 0.01). Monoclonal antibody to TNF prevented all abnormalities and had 100% survival. Hemodynamic events were similar in both groups, but metabolic acidosis was attenuated with ibuprofen. CONCLUSIONS: TNF stimulates arachidonic acid metabolism in vivo. A cyclooxygenase inhibitor attenuates eicosanoid synthesis and dramatically improves survival. TNF appears to have different effect on tissues that synthesize certain eicosanoids. Hypotension from TNF is not mediated via the eicosanoids. TNF-induced mortality, like endotoxemia/sepsis may be mediated, in part, via arachidonic acid metabolites. These new findings support the notion that cyclooxygenase inhibitors may be used as adjunctive therapy in clinical sepsis.

Ventral/incisional abdominal herniorrhaphy by fascial partition/release.

Ventral/incisional abdominal hernias following celiotomies continue to be a vexing problem for both patients and general and plastic and reconstructive surgeons, since no universally applicable preventive or reconstructive techniques have evolved. With reference to reconstruction, for example, primary repair is associated with a high incidence of recurrence; utilization of synthetic mesh is susceptible to extrusion, infection, and intestinal fistulization; and employment of truncal or extremity, free or rotational, myofascial flaps is associated with the morbidity of the procedure per se. By contrast, the use of fascial partition/release of the components of the abdominal wall employing bilateral parasagittal relaxing incisions in the obliquus externus abdominis and/or transversus abdominis fascia facilitates coaptation of the linea alba and obviates the aforementioned morbidity. This technique was utilized electively in seven adult patients with large defects of the anterior abdominal wall. In addition, for two patients, synthetic nonabsorbable mesh was applied superficial to the midline fascial closure. During a mean follow-up interval of 18 months (range 6 to 36 months), each patient healed per primum without evidence of eventration or herniation. The theoretic and pragmatic advantages of this technique are discussed. The use of fascial partition/release for reconstruction of abdominal wall defects should be part of the armamentarium of all herniotomists.

Matronized nursing service at Mobile City Hospital in the mid-19th century: a paradigm of altruism and indigent patient care.

Influences upon the development and evolution of nursing groups and the profession have been multifactorial: cultural, economic, political, and social. Although monastic and chivalric orders throughout antiquity provided the beginnings with hierarchical organizations and a sense of voluntarism and vocation, it was not until the mid-19th century that the concept of a nursing service became codified and more hospital-oriented. The inception of a matronized nursing service in the Mobile City Hospital under the tutelage of the Superintendent, Dr. Willis Roberts, antedated the rapid expansion of nursing education and service recommended and instituted by Florence Nightingale. The former served as a paradigm of altruism as "women attendants" became formally associated with a hospital-based "nursing service," initially under the directorship of a lay matron, Mrs. Sarah Dubois, and subsequently under a succession of Sisters of the Roman Catholic Order of the Sisters of Charity (America). Although ostensibly instituted to render care to "female paupers," the matronized nursing service was readily expanded, and subsequently delivered care to the entire, predominantly indigent patient population. The paradigm was worthily perpetuated during the latter half of the 19th century in vitually all hospitals as nursing education and services continued to become more secularized and technologically sophisticated.

A surgical diary: concepts and tenets.

A surgical diary may be one of the most utilitarian mechanisms for acquiring, recalling, and reinforcing surgical knowledge and skills. A surgical diary facilitates capture of the subtlety of each operation as provided by a diarist's preceptors, incorporating and utilizing what is valid and rejecting and discarding what is otherwise. Use of a surgical diary could be an effective learning instrument.

Medical College of Alabama in Mobile, 1859-1920: a legacy of Dr. Josiah Clark Nott.

The first legislated orthodox medical school within Alabama was founded in Mobile in 1859, a legacy of Dr. Josiah Clark Nott. That it developed later than other Southern medical schools has been attributed to multiple factors, among them rural isolation, restricted communication, limited transportation, sparse population, cultural deprivation, and climatologic enervation. The rationale for a medical school within Alabama was also multifactorial: to supply physicians to rural Alabama, to reverse the economic and cultural drain among Alabamians that out-of-state education implied, and to educate medical students regarding the unique health care requirements of a predominantly rural Alabama populace. A medical school building was constructed east of the Mobile City Hospital, and was equipped with an elegant collection of anatomic models acquired by Nott during his travels in western Europe in 1859. After only two sessions, however, the War Between the States (1861 to 1865) forced the medical school to close, as faculty and students joined the Confederate forces. In 1868, with the continued involvement of Dr. W. H. Anderson as Dean, the institution was reopened. During the succeeding 52 years of its existence, the financially strapped medical school attempted to cope with evolving medical technologies and educational philosophies. Despite the commitment of the administrators and faculty, sociopolitical factors and insufficient economic support militated against the school's continued existence. Nott has been characterized as a physician, anatomist, anthropologist, and ethnologist. His opinions as revealed in his writings were controversial because they addressed sociopolitical and racial issues. Nevertheless, his commitment to the Medical College of Alabama in Mobile was unstinting, and he provided the major leadership role in its establishment.
