Sacrococcygeal pilonidal disease: sinotomy versus excisional surgery, a retrospective study

Pilonidal disease is a disease of relatively young people, the exact aetiology of which is unknown. Treatment options vary from simple incision to complex flap procedures. Each method has its advocates and they all have a variable recurrence rate. The multiplicity of procedures testifies to the lack of an optimal treatment method. The objective of this study is to compare sinotomy, that is, simply laying the sinus open with the more popular radical surgery, where the sinus-bearing tissues are excised. Patients who were admitted to Aseer Central Hospital, Saudi Arabia with a pilonidal sinus or abscess, in the period from April 1999 to January 2005, were identified. The medical records were reviewed and data related to the patient characteristics, disease process and the procedures carried out were noted. Identified patients were contacted by phone to check recurrence of the disease and their abidance to instructions regarding regular hair removal from the area. Eighty-one patients were included in the study. The median age was 24.2 years (range 16-60 years). There were 9 women and 72 men. All procedures were carried out under general anaesthesia except sinotomy, which was carried out under general or local anaesthesia. The surgical procedure was incision and drainage of abscess in 16 cases (19.8%), excision with primary closure in 29 cases (35.8%), excision by the open method in 15 cases (18.5%), sinotomy in 14 cases (17.3%) and rhomboid flap construction in 8 cases (9.9%). The overall recurrence rate was 26.9%, and the mean hospital stay was 4.1 days. Sinotomy had a low recurrence rate (12.5%) and a short hospital stay (2.8 days). Sinotomy has the advantages of simplicity, the possibility of operating under local anaesthesia, with an acceptable recurrence rate. We recommend sinotomy for pilonidal sinus and abscess alike, both in primary and recurrent cases.     

Black cohosh and fluoxetine in the treatment of postmenopausal symptoms: A prospective,randomized trial

The objective of this study was to evaluate the efficacy of fluoxetine and black cohosh in the treatment of women with postmenopausal symptoms. A total of 120 healthy women with menopausal symptoms were recruited to this prospective study with a follow-up period of 6 mo. They were randomly assigned to 1 of 2 groups and were treated with fluoxetine or black cohosh. After entry into the study, patients were examined at the first, second, third, and sixth months of the treatment period. The women kept diaries in which they reported the daily number and intensity of hot flushes and night sweats. In addition, at the beginning and end of the third month, they completed questionnaires consisting of a modified Kupperman Index, Beck’s Depression Scale, and a RAND-36 Quality-of-Life Questionnaire. Statistically significant differences were noted in the Kupperman Index and Beck’s Depression Scale at the end of the third month in both groups compared with baseline values. In the black cohosh group, the Kupperman Index decreased significantly compared with that in the fluoxetine group by the end of the third month. On the other hand, in the fluoxetine group, Beck’s Depression Scale decreased significantly compared with that in the black cohosh group. Monthly scores for hot flushes and night sweats decreased significantly in both groups; however, black cohosh reduced monthly scores for hot flushes and night sweats to a greater extent than did fluoxetine. At the end of the sixth month of treatment, black cohosh reduced the hot flush score by 85%, compared with a 62% result for fluoxetine. By the sixth month of the study, 40 women had discontinued the study—20 (33%) in the fluoxetine group and 20 (33%) in the black cohosh group. Compared with fluoxetine, black cohosh is more effective for treating hot flushes and night sweats. On the other hand, fluoxetine is more effective in improvements shown on Beck’s Depression Scale.     

LIF-immobilized nonwoven polyester fabrics for cultivation of murine embryonic stem cells

Embryonic stem (ES) cells have a great interest for tissue engineering because of their pluripotent nature and proliferative capacity. The objective of this study is to constitute a synthetic microenvironment to support the in vitro propagation of murine ES cells in an undifferentiated state. That is why we used a three-dimensional matrix, nonwoven polyester fabric (NWPF), which was formed from poly(ethylene terephthalate) (PET) fibers. NWPF discs were partially hydrolyzed, and then the carboxyl groups were coupled with leukemia inhibitory factor (LIF) in the presence of water-soluble carbodiimide. The effectiveness of immobilization process was checked with ATR-FTIR spectroscopy, fluorimetry, and cell culture studies. ES cell colony morphology, alkaline phosphatase (AP) activity, stage-specific embryonic antigen-1 (SSEA-1) immunoreactivity, and SEM analysis following a 72 - 96-h culture period upon hydrolyzed and LIF-immobilized surfaces were assessed to determine the pluripotent status of ES cells. Results revealed that LIF was active in immobilized form; undifferentiated colonies had not only a significant AP and SSEA-1 immunoreactivity, but also a higher undifferentiated colony ratio on LIF-immobilized surfaces than that of hydrolyzed surfaces. The immobilized LIF protein might be a good model to provide a feeder-free system, but the physical properties of the scaffold is more convenient for differentiation studies.     

Focal Headache During Balloon Inflation in the Vertebral and Basilar Arteries

SYNOPSIS
Background and Purpose: Headache may be seen in acute cerebrovascular disease. The significance of localized headache in association with vertebrobasilar disease has not been recognized.
Summary of Report: We describe a patient with a cerebellar arteriovenous malformation who underwent intravascular balloon occlusion of the vertebral and basilar artery. He developed reproducible patterns of referred pain with balloon inflation at specific sites.
Conclusions: Well localized head pain in the setting of acute stroke should alert physicians to the possibility of localized arterial injury. The pattern seen in this patient has been documented in experimental situations, and should be of use in the setting of acute stroke.     

Estimates of the prevalence of arthritis and other rheumatic conditions in the United States. Part II

OBJECTIVE: To provide a single source for the best available estimates of the US prevalence of and number of individuals affected by osteoarthritis, polymyalgia rheumatica and giant cell arteritis, gout, fibromyalgia, and carpal tunnel syndrome, as well as the symptoms of neck and back pain. A companion article (part I) addresses additional conditions. METHODS: The National Arthritis Data Workgroup reviewed published analyses from available national surveys, such as the National Health and Nutrition Examination Survey and the National Health Interview Survey. Because data based on national population samples are unavailable for most specific rheumatic conditions, we derived estimates from published studies of smaller, defined populations. For specific conditions, the best available prevalence estimates were applied to the corresponding 2005 US population estimates from the Census Bureau, to estimate the number affected with each condition. RESULTS: We estimated that among US adults, nearly 27 million have clinical osteoarthritis (up from the estimate of 21 million for 1995), 711,000 have polymyalgia rheumatica, 228,000 have giant cell arteritis, up to 3.0 million have had self-reported gout in the past year (up from the estimate of 2.1 million for 1995), 5.0 million have fibromyalgia, 4-10 million have carpal tunnel syndrome, 59 million have had low back pain in the past 3 months, and 30.1 million have had neck pain in the past 3 months. CONCLUSION: Estimates for many specific rheumatic conditions rely on a few, small studies of uncertain generalizability to the US population. This report provides the best available prevalence estimates for the US, but for most specific conditions more studies generalizable to the US or addressing understudied populations are needed.     

Neonatal osteofibrous dysplasia associated with pathological tibia fracture: a case report and review of the literature

Osteofibrous dysplasia is a rare and benign disease that originates from the tibia or fibula. The symptoms of osteofibrous dysplasia include painless enlargement and bowing of the tibia and pain occurring in the presence of pathological fracture. Herein a male infant who was admitted with redness and swelling on the right leg and diagnosed as pathological tibia fracture due to left tibia osteofibrous dysplasia on the third day of life was presented. To our knowledge, this is the earliest presentation of osteofibrous dysplasia with a pathological fracture in a neonate. Therefore, it must be suspected in neonatal bone fractures.     

Improvement of Colonic Healing by Preoperative Rectal Irrigation With Short-Chain Fatty Acids in Rats Given Radiotherapy

BACKGROUND We investigated the effect of preoperative rectal irrigation with short-chain fatty acids on irradiated colonic anastomosis in rats.METHODS Sixty male Wistar rats were divided into four groups. Group I (control group, n = 15) underwent left colon resection and primary anastomosis. Group II (Short-chain fatty acids pretreatment group, n = 15) had short-chain fatty acids rectal irrigation for five days preoperatively. Group III (preoperative radiotherapy group, n = 15) underwent irradiation to the whole pelvis eight and four days before the operation, for a total dose of 20 Gy. Group IV (preoperative radiotherapy group + short-chain fatty acids pretreatment group, n = 15) had rectal irrigation with short-chain fatty acids for five days after the second irradiation. Within each group, animals were anesthetized to assess the clinical, mechanical, histologic, and biochemical parameters of anastomotic healing on either the third or seventh postoperative days.RESULTS The mean bursting pressure was significantly low in Group III on Day 3 and was significantly high in Group IV on Day 7 (P = 0.001, P = 0.021). The burst occurred at the anastomoses in all animals tested on the third postoperative day, and outside of the anastomoses in all animals tested on the seventh postoperative day. The histologic parameters of anastomotic healing, such as epithelial regeneration and formation of granulation tissue, were significantly improved by use of preoperative rectal irrigation with short-chain fatty acids on Day 7. The amount of total and salt-soluble collagen concentrations significantly increased in Group IV compared with the control group on Day 3 (P = 0.008, P = 0.004).CONCLUSION Some mechanical and histologic aspects of colonic anastomotic healing can be adversely affected by preoperative radiotherapy, but rectal irrigation with short-chain fatty acids may improve anastomotic healing.Supported by The Turkish Surgical Society, as funded by a grant from the Sanofi Pharma.
