Oesophageal achalasia: An argument for primary surgical management

Achalasia is a primary oesophageal motility disorder resulting from damage to the ganglion cells of the myenteric plexus. Impaired relaxation of the lower oesophageal sphincter and aperistalsis causes its cardinal symptoms of dysphagia, chest pain and reflux-type symptoms. Management is somewhat controversial, with options including systemic and local pharmacotherapy, dilatation and oesophagomyotomy. We review the presentation, investigation and management of oesophageal achalasia and make an argument for primary surgical management. We performed a Medline search of the term 'achalasia', limiting the search to clinical trials and meta-analyses. We then selected articles based on their abstracts using four main criteria: previously unreported findings, previously unreported techniques, size of patient cohort and journal impact factor. References in selected articles were manually searched for other relevant articles. Achalasia has been managed using a variety of techniques including systemic and local pharmacotherapy, forced dilatation and oesophagomyotomy. Success rates vary widely between techniques. Mechanical disruption ofthe lower oesophageal sphincter is most successful. In achalasia, mechanical disruption of the lower oesophageal sphincter using forced dilatation or surgical myotomy offers the only realistic prospect of long-term symptom relief. Recent evidence suggests that previous medical treatment or dilatation makes oesophagomyotomy more difficult and increases the risk of complications. As the morbidity associated with surgery continues to decrease with improvements in minimal access techniques, the argument for primary management of achalasia with oesophagomyotomy becomes more compelling.

Essential tremor leading to toxic liver damage successfully treated with deep brain stimulation

We present a patient with severe essential tremor (ET), who underwent thalamic deep brain stimulation (DBS). After previous medical treatment with Propranolol and Primidone failed, the patient resorted to alcohol, which greatly alleviated the symptoms. The downside of this situation, however, was that it led to alcoholism with severely disturbed liver enzymes and hepatic steatosis. After DBS the patient was free of tremor and thus could easily abstain from alcohol. In time the elevated liver enzymes returned to normal, which indicates that sufficient tremor control by DBS can help these patients to abstain from alcohol.

Children with high and intermediate imperforate anus: remembering and talking about medical treatment carried out early in life

Treatment of children with high and intermediate imperforate anus entails several different surgical procedures during the first 3-12 months of life, which are accompanied by a strict follow-up treatment regimen. It has not been studied whether the children remember this treatment carried out early in life. Research has shown that small children may demonstrate so-called non-verbal memories of salient events occurring in early childhood. The purpose was to examine whether children with imperforate anus showed distressing memories of previous medical treatment and whether parent-child dialog about medical treatment is related to the child's psychosocial functioning later in life. Parents of 25 children (9 boys, 16 girls) with high and intermediate imperforate anus participated in the study. The mean age among the children was 10.5 years (range 8.0-13.6). A comparison group of 30 children (5 boys and 25 girls) with juvenile chronic arthritis also participated in the study. The mean age was 10.6 years (range 7.8-13.6). All parents answered the Child Behavior Checklist (CBCL/4-18) and a study-specific questionnaire. Children in both groups were reported to show distressing memories of early treatment. Children who had been talked to showed good psychosocial function and were in a better mood and less angry than those who had not been talked to. Parent-child discussions about the child's experiences of medical treatment did not seem to be harmful or in any other way detrimental to the child, instead such discussions seemed to facilitate the child's psychosocial functioning.

Helicobacter pylori‐Induced Damage to the Gastric Mucosa is Not Modulated by Previous Vagotomy or Medical Treatment of Peptic Ulcer Disease: A Comparative Study of Vagotomized Patients, Medically Treated Peptic Ulcer Patients and Community Control Subjects

An increase in the prevalence of precancerous lesions and atrophic changes in the gastric mucosa has been reported as long-term consequences of vagotomy-induced acid suppression. This study was designed to describe the long-term changes in the gastric mucosa caused by vagotomy and Helicobacter pylori infection. Seventy-nine patients with vagotomized peptic ulcers, 70 nonoperated patients with peptic ulcers, and 85 matched community control subjects were randomly selected to participate in an upper endoscopic study. Biopsy specimens were taken from predestined locations of the gastric mucosa. Mean follow-up time for the vagotomized patients was 17.3 (range, 6-28) years and 12.7 (range, 10-17) years for the medically treated peptic ulcer patients. In H. pylori-positive subjects, severe atrophic changes in the distal gastric mucosa (prepylorus and angulus) was found in 30% (95% confidence interval (CI), 19-43) of the vagotomized patients and in 43% (95% CI, 29-58) of medically treated patients with peptic ulcers, and in 32% (95% CI, 20-46) of the community control subjects. Severe intestinal metaplasia was not found more frequently in vagotomized peptic ulcer patients compared with medically treated patients with peptic ulcers (p = 0.5). The histological picture of the age-matched community control subjects did not differ significantly from the patients with peptic ulcers when corrected for presence of H. pylori infection. This study lends no support to theories of increased premalignant changes in the gastric mucosa of vagotomized patients. H. pylori infection rather than long-term acid suppression seems to be the explanation of the gastric mucosal changes seen after vagotomy.

Surgical excision of extensive anal condylomata not associated with risk of anal stenosis

Surgical treatment of extensive and confluent anal condylomata results in large open wounds, which in other contexts of anorectal surgery (e.g., hemorrhoidectomy), have been associated with a relevant risk of stricture formation. The aim of our study was therefore to revisit the issue and assess this risk and the general morbidity in patients undergoing extensive excision and fulguration of anal warts. Records of 41 consecutive patients undergoing with excision/fulguration of extensive, i.e., >50% confluent anal condylomata were retrospectively reviewed. Excluded were patients with a lesser degree of warts and patients lost to follow-up before complete wound healing. Data recorded included patient characteristics and evolution of the local area after the surgery. Forty-one patients (40 males and one female) underwent excision and fulguration of a large anal condyloma with an average follow-up of 6 months (range, 1-36 months). The majority of patients (97.6%) were HIV-positive with 80% taking antiretroviral medication. Half of the patients had not received any previous medical or surgical treatment, whereas one fourth had undergone surgical excisions or fulgurations before. Recurrent warts developed in 19 patients (46.3%). The surgical morbidity after the extensive excision consisted of bleeding (22%). However, none of the patients showed any evidence or complaints of postoperative stricturing and anal stenosis at follow-up. Excision of extensive anal condylomata has a known high probability of recurrences, but the risk of developing anal stenosis is low. Careful primary excision of even confluent warts can therefore be safely performed without major primary flap reconstructions.

Cyclooxygenase-2 overexpression in ovarian endometriomas is associated with higher risk of recurrence

Cyclooxegenase-2 expression was evaluated by immunohistochemistry in endometrioma tissue samples taken from 109 patients, of whom 53 had recurrence by 30 months after surgery and 56 did not. Cyclooxegenase-2 overexpression, along with previous medical treatment of endometriosis and the presence of adhesion, is predictive of recurrence of ovarian endometrioma within 30 months after surgery, with a resultant sensitivity of 72.5% and a specificity of 72.4%, suggesting that there are intrinsic and identifiable biomarkers that confer recurrence risk.

A case of intractable pruritus in Turner’s syndrome successfully treated with molecular adsorbent recirculating system

Pruritus is the most disabling symptom in patients with cholestatic liver diseases, such as primary biliary cirrhosis, primary sclerosing cholangitis and drug induced cholestasis. Many drug therapies have been used for treating pruritus in these patients, such as histamine antagonists, ursodeoxycholic acid, cholestyramine, enzyme inducing agents as rifampicin or phenobarbital, for inactivation of putative peripheral pruritogens, and finally opioid antagonists as naloxone or naltrexone, which modulate altered central neurotransmission. Other methods have been tried in patients who do not respond to medical therapies. Extracorporeal albumin dialysis with the molecular adsorbent recirculating system (MARS) is used for the treatment of acute decompensation of chronic liver disease, acute liver failure, liver failure after surgery or liver transplantation [1, 2]. It has also been claimed that it may be useful in intractable pruritus in cholestatic syndromes [1, 3, 4]. We report the effect of this treatment in a patient with Turner’s syndrome and drug induced cholestasis refractory to medical therapy. A 54-year-old woman came to our attention because of intractable pruritus. She was affected by Turner’s syndrome (karyotype 45, X0),and hypothyroidism. Since the age of 23 years she had suffered of amenorrea and she had been treated with estro-progestinic therapy for many years. One year before hospitalisation, her therapy was changed into tibolone at a dose of 2.5 mg once daily. Approximately 6 months later, the patient presented itching and mild jaundice, she was admitted to the hospital and a percutaneous liver biopsy was performed; it revealed a pattern of drug induced cholestatic hepatitis. She was treated with ursodeoxycholic acid, cholestiramine and histamine antagonist, and a resolution of jaundice occurred. After an initial improvement of pruritus, later on she suffered from a severe relapse, in spite of continuing medical therapy. Six months later she was admitted to our hospital; the patient presented scratching skin lesions on arms and legs and sleep deprivation that made worse her quality of life. Our laboratory data demonstrated a normal liver function (Child-Pugh-Turcotte: A5), a moderate elevation of transaminases (GOT: 55 U/L, GPT: 51 U/L) and elevated AP: 863 U/L and gGT: 53 U/L. Bilirubin level was within normal values. Autoimmune liver disease was excluded because of negative antimytochondrian antibodies, antinuclear antibodies, antineutrophilic cytoplasm antibodies, smooth muscle antibodies, C-reactive protein, rheumatoid factor. Hepatic ultrasonography was normal. Taking into account the unsuccessful previous medical treatment we decided to treat the patient with the extracorporeal albumin dialysis (MARS). The MARS system (MARS module: Teraklin AG, Rostock, Germany) was used in combination with a standard dialysis machine. The blood flow was set to 185 ml/min, the flow in the closed albumin dialysate E. Silvagni B. Stagni L.

Contemporary Prostate Cancer Prevalence among T1c Biopsy-Referred Men with a Prostate-Specific Antigen Level ≤ 4.0 ng per Milliliter

ObjectiveTo investigate the prostate cancer (PCa) prevalence and risk factors of men with prostate-specific antigen (PSA) level≤4.0ng/ml and an unsuspicious digital rectal examination (DRE) in a large biopsy referral cohort. Materials and methodsBetween 1997 and 2005, 855 men underwent initial transrectal ultrasound (TRUS)-guided prostate biopsy at the University Hospital Hamburg-Eppendorf. Patients with any previous surgical or medical treatment were excluded from analyses. Logistic regression analyses were performed to determine risk factors of PCa at biopsy and high-grade PCa defined as biopsy Gleason sum≥7. ResultsOverall PCa detection rate was 23.1%. The majority had a biopsy Gleason sum of 6 (79.5%) and 20.5% had a biopsy Gleason sum≥7. Total PSA (tPSA) and percentage of free PSA (%fPSA) were statistically significantly different in men with and without PCa (all p<0.001). In tPSA strata ≤ 0.5, 0.6–1.0, 1.1–2.0, 2.1–3.0, and 3.1–4.0ng/ml, PCa prevalence was 4.0%, 10.6%, 14.8%, 24.5%, and 32.1%, respectively. In logistic regression analyses addressing PCa and Gleason sum ≥ 7 at biopsy, %fPSA and prostate volume represented independent and most informative risk factors. ConclusionOur data demonstrate that a substantial percentage (23.1%) of men with a PSA≤4.0ng/ml and an unsuspicious DRE in a biopsy referral population harbor PCa, with 20.5% being high grade. Low %fPSA and low prostate volume represent important parameters in PCa and in high grade disease detection at biopsy, respectively.

Polycystic ovaries and the polycystic ovary syndrome phenotype in women with active acromegaly

Previous retrospective studies have suggested that women with acromegaly may present with menstrual irregularity and symptoms/signs of hyperandogenism, a phenotype similar to that of the polycystic ovary syndrome (PCOS). The aim of this study was to investigate prospectively the presence of the PCOS phenotype (PCOSP) and polycystic ovaries (PCO) on ultrasonography in women with active acromegaly. Women within the reproductive age range (21-43 years) with active acromegaly of recent onset and/or previous surgical and/or medical therapy were studied. Subjects underwent a physical examination; fasting bloods for androgens, pituitary hormones and metabolic parameters; an oral glucose tolerance test (OGTT) to estimate disease activity and insulin resistance; and a transvaginal ultrasound. Six women had newly diagnosed acromegaly, and eight still had active disease following previous surgical and/or medical treatment. Seven women were found to have PCO and six fulfilled the criteria for PCOSP; six of these women, five with PCOSP, had a pituitary macroadenoma. Women with PCOSP had significantly increased mean ovarian volumes and characteristic ovarian morphology compared to women without PCOSP (P < 0.05), higher levels of IGF-1 and testosterone and lower SHBG levels that did not reach statistical significance. A positive correlation between IGF-1 and mean ovarian volume was identified only in women with PCOSP (r = 0.851, P < 0.05). PCO and PCOSP are relatively common in women with acromegaly and may account for some of the symptoms related to gonadal dysfunction irrespective of the size of the pituitary tumour. It is likely that IGF-1 alone or in combination with GH and/or insulin resistance may be involved.

Patterns of and Risk Factors for Recurrence in Women With Ovarian Endometriomas

To identify risk factors for and the patterns of recurrence of endometrioma and of dysmenorrhea in women with ovarian endometrioma. We evaluated 710 consecutive patients operated on for ovarian endometriomas who were followed up for an average of 22.4 months. Twenty factors were examined to assess their effect on risk of recurrence of endometrioma and of dysmenorrhea using survival analysis. Hazard rate also was estimated to examine recurrence patterns. For recurrence of endometrioma, the revised American Fertility Society (rAFS) score, younger age at surgery, and previous medical treatment of endometriosis were identified to be risk factors. For recurrence of dysmenorrhea, rAFS score was the only risk factor. For both recurrences, there was a constant hazard rate in the first 28-30 months after surgery, indicating that the recurrence in that period is completely random. After that period, the hazard rate increased dramatically. The total rAFS score, but not rAFS stage, is a risk factor for recurrence of both endometrioma and dysmenorrhea, indicating that the rAFS stage has little prognostic value. The existence of a completely random recurrence period may be a universal phenomenon, with its duration and the magnitude of recurrence risk determined by patient characteristics and quality of care. The second phase of much higher recurrence risk may reflect successful reseeding, reimplantation, and regrowth of ectopic endometrium. Therefore, the identification of risk factors as well as patterns of recurrence should shed better light on possible causes for recurrence, which is now poorly understood.

Expression of PD-1, PD-L1, and PD-L2 in the Liver in Autoimmune Liver Diseases

PD-L1 (also B7-H1) and PD-L2 (also B7-DC) are ligands for programmed death-1 (PD-1), which is a member of the CD28/B7 superfamily of costimulatory molecules and plays an inhibitory role on the periphery. Impaired regulation of this system may cause disruption to self-tolerance leading to autoimmunity; however, the role of these molecules in the liver is unknown. Therefore, we examined the expression of PD-1, PD-L1, and PD-L2 in the liver in autoimmune liver diseases. We examined the liver expression of these molecules in autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) with no previous medical treatment using immunohistochemical staining and real-time PCR, and compared with chronic hepatitis type C (CHC) as a control. Although PD-1, PD-L1, and PD-L2 were expressed in the liver in AIH, PBC, as well as CHC, the expressions were relatively lower in PBC. In AIH, despite more severe inflammation than in CHC, the expression of these molecules was not greater than in CHC, and when compared with the relative expression of PD-L1, PD-L2 was lower in AIH. PD-L1 and PD-L2 expressions were well correlated with the level of IFN-gamma; however, relatively decreased induction for PD-L1 and PD-L2 by IFN-gamma was observed in AIH or PBC than in CHC. Modulation of PD-1/PD-L1 and PD-L2 systems may play a role in the development of autoimmune liver diseases.

A study of the spectrum of Acanthamoeba keratitis: A three-year study at a tertiary eye care referral center in South India

To determine the epidemiological and clinical characteristics of Acanthamoeba keratitis and also to determine the sensitivity and specificity of smears in the detection of Acanthamoeba. A retrospective review of all culture-positive cases of Acanthamoeba keratitis seen between October 1999 and August 2002 was performed. Corneal scrapes were subjected to culture and microscopy using standard protocols. Out of 3183 consecutive patients with clinically diagnosed corneal ulcers evaluated, 33 (1.04%) were found to be due to Acanthamoeba. Twenty-four out of 33 (72.72%) were less than 51 years of age (P<0.001). All patients were from rural areas (P<0.001) and 26 (78.79%) of them were agricultural workers (P=0.031). All 33 had history of corneal injury (P<0.001) and 28 (84.85%) patients had injury with mud (P<0.001). All 33 (100%) patients had previous medical treatment (P=0.009) and 10 (30.3%) had used traditional eye medicines (P=0.183). A clinical pattern of ring infiltrate was characteristic in 15 (45.45%) patients. The diameter of the corneal ulcer was more than 6 mm in 27 (81.82%) eyes (P<0.001). Twenty-six (78.79%) patients had visual acuity of perception of light on initial presentation (P<0.001) and 24 (72.73%) had the same as their final visual outcome. The sensitivity of 10% potassium hydroxide (KOH) preparation was found to be higher (P<0.001) in the detection of Acanthamoeba cysts. The incidence of Acanthamoeba keratitis amongst the corneal ulcer patients was 1% in this setting and it was mainly due to corneal injury by mud. The KOH preparation is a sensitive diagnostic tool for the detection of Acanthamoeba. Delayed diagnosis or misdiagnosis and inappropriate antimicrobial therapy results in poor visual outcome.

THE SECONDARY AND RECURRENT ABDOMINAL COMPARTMENT SYNDROME

Introduction: The Secondary Abdominal Compartment Syndrome (SACS) refers to cases of the ACS that do not originate from the abdominopelvic region. With greater awareness of the physiologic consequences of raised intra-abdominal hypertension (IAH), cases of the SACS are being increasingly described. The prior treatment or the presence of a partially open abdomen does not preclude the ACS if the abdomen and viscera continue to swell or the clinician is not vigilant in monitoring intra-abdominal pressure (IAP). Such recurrent cases (RACS) have been defined as those which redevelop following the previous medical or surgical treatment of primary or SACS. Although there has been a diverse range of etiologies implicated, these cases seem to be linked by the common occurrence of severe shock requiring aggressive fluid resuscitation. The aim of this paper is to thus to review the historical background, awareness, definitions, pathophysiological implications and treatment options for SACS and RACS.Methods: This review will focus on the available literature regarding SACS and RACS. A Medline and Pubmed search was performed using the keywords; secondary abdominal compartment syndrome AND secondary AND tertiary AND recurrent AND abdominal compartment syndrome AND intra-abdominal pressure AND intra-abdominal hypertension. Bibliographies of recovered papers were hand-searched for other appropriate references. The resulting references were included in the current review on the basis of relevance and scientific meritResults: There has been remarkably little specific study of these entities outside of specific groups such as those injured by thermal or traumatic injury. The epidemiology, risk factors for, treatment of and most importantly, strategies for prevention all remain scientifically unknown and therefore based on opinion. Notable, although small, studies suggest that specific resuscitation practices may avert these conditions.Conclusions: ACS can occur in any patient who is critically ill and subject to visceral and somatic swelling, regardless of whether the inciting pathology is extra-abdominal. The ACS may also reoccur with recurrent shock and swelling even if previous therapies had partially addressed IAH. Therefore IAP measurements should be considered a routine monitoring for the critically ill, especially those subjected to shock and requiring a subsequent resuscitation. Much further study is required to understand the differences in etiology, diagnosis, pathophysiology, and treatment for all cases of the ACS.

The results of nucleoplasty in patients with lumbar herniated disc: a prospective clinical study of 52 consecutive patients

Nucleoplasty is a minimally invasive, percutaneous procedure that uses radiofrequency energy to ablate nuclear material and create small channels within the disc. To evaluate the efficacy of nucleoplasty technique in patients with leg pain caused by radicular encroachment. A prospective clinical study of subjects with lumbar disc herniation, and radicular pain resistant to previous medical treatment and physiotherapy for a period of at least 3 months. Fifty-two consecutive patients with leg pain and magnetic resonance imaging evidence of small and medium-sized herniated discs correlating with the patient's symptoms (contained disc herniation<6 mm, with a disc height>/=50% in comparison to normal adjacent discs) were included. Visual analogue scale (VAS) was administered and Oswestry disability questionnaires were filled out at preprocedure and postprocedure 2 weeks, 6 months, and 1 year. Reduction of analgesic treatment and the patients' satisfaction were also recorded. All procedures were performed under local anesthesia and fluoroscopic guidance on an outpatient basis. Patients underwent discography to evaluate annular integrity just before nucleoplasty. Channels were created in the nucleus by advancing the radiofrequency probe (ablating) and withdrawing it (coagulation). In all patients six channels were created. Thirty-four patients had one and 18 had two discs treated; a total of 70 procedures were performed. Mean age of patients was 44.8+/-8.6 years. The mean follow-up period was 12.1+/-1.6 months. Mean VAS reduced from preprocedure 7.5 to 3.1 at postprocedure 6 months and to 2.1 at the latest follow-up. Mean Oswestry index decreased from 42.2 to 24.8 at 6 months and to 20.5 at the latest examination. Analgesic consumption was stopped or reduced in 42 patients (85%) at 6 months and in 46 patients (94%) 1 year after the procedure. Overall patient satisfaction was 81% at 2 weeks, 85% at 6 months, and 88% at the latest follow-up. There were no complications related to the procedures. Our results encourage us to use nucleoplasty in carefully selected patients with leg pain caused by radicular encroachment. We recommend applying this minimally invasive technique only in those patients with small (<6 mm) contained disc herniations, with a disc height of>or=50% and with annular integrity.

The Low Prevalence of Helicobacter pylori Gastritis in Children with Newly Diagnosed IBD Cannot Be Implicated in Previous Medical Treatment

The Low Prevalence of <i>Helicobacter pylori</i> Gastritis in Children with Newly Diagnosed IBD Cannot Be Implicated in Previous Medical Treatment

Are Narrow-Band Ultraviolet B Home Units a Viable Option for Continuous or Maintenance Therapy of Photoresponsive Diseases?

Phototherapy is an effective treatment for several photoresponsive diseases. Many patients are unable to attend hospital-based treatment and prefer home phototherapy. The purpose of this study is to survey patients who were prescribed home phototherapy to determine the viability of narrow-band ultraviolet B home units in the continuous or maintenance treatment of photoresponsive diseases. A patient questionnaire was prepared focusing on different areas of interest: the reason for choosing home therapy, appropriate teaching, previous medical treatment, present exposure therapy, improvement of the condition, side effects, regular dermatologic follow-ups, and the effectiveness of this approach. Twenty-seven patients who attended the photodermatology clinics at the Sisters of Charity of Ottawa Health Service at the Elisabeth Bruyère Health Centre in Ottawa and the Ottawa Hospital Civic Campus were contacted, and they completed a questionnaire by telephone or electronic mail. Twenty-five patients completed the questionnaire. One refused to participate, and one was out of the country. The main reasons for choosing home phototherapy were time (40%), travel expenses (25%), difficulty with work schedule (17%), and recommendation by a physician (6%). Other reasons included loss of earnings, personal stress, knowledge that the disease recurs when phototherapy is discontinued, moving from the city, personal stress, and the convenience of being at home. Regarding the effectiveness of the home phototherapy, 24 patients (96%) viewed the home unit approach to be effective. All patients agreed that they would continue the treatment; they would repeat it, and they would recommend it. Few patients reported side effects, such as erythema (36%), blisters (1%), pruritus (8%), and dryness (1%). Fourteen patients (56%) reported not experiencing any side effects. Narrow-band ultraviolet B home phototherapy was found to be an effective form of maintenance therapy for photoresponsive diseases. It is safe and presents few side effects when patients receive appropriate guidelines, teaching, and follow-ups.

Management of 13 cases of canine respiratory disease using inhaled corticosteroids

To determine the value of inhaled corticosteroids in the management of chronic inflammatory airway disease in dogs. Medical records of dogs that were presented for the investigation of respiratory disease were reviewed retrospectively. Criteria for inclusion were knowledge of previous medical treatment including side effects, diagnosis of the underlying disease, use of inhaled corticosteroids and at least two-months follow-up data. Thirteen dogs that fulfilled the criteria were identified. Ten dogs were diagnosed with chronic bronchitis and three with eosinophilic bronchopneumopathy. Four dogs had not previously received corticosteroid treatment for their respiratory disease, and all these showed a reduction or a resolution of clinical signs without obvious side effects after inhaled corticosteroid therapy. Nine dogs had previously received oral or parenteral corticosteroids for treatment of their respiratory disease, and all had exhibited side effects. Five of these dogs were treated with inhaled corticosteroids alone, and all exhibited an improvement in clinical signs without observable side effects. The remaining four dogs were treated with a combination of inhaled and oral corticosteroids, and all showed improvement in clinical signs and reduction in side effects. Inhaled medication was well tolerated in all dogs. Inhaled corticosteroids were used for the management of chronic bronchitis and eosinophilic bronchopneumopathy in 13 dogs, and these may have the advantage of reducing side effects associated with oral corticosteroids.

Recurrence of ovarian endometrioma after laparoscopic excision

To analyse risk factors that influence the recurrence of endometrioma after laparoscopic excision. A total of 224 patients who had a minimum of 2 years of post-operative follow-up after laparoscopic ovarian endometrioma excision were studied retrospectively. Recurrence was defined as the presence of endometrioma more than 2 cm in size, detected by ultrasonography within 2 years of surgery. Fourteen variables (age, presence of infertility, pain, uterine myoma, adenomyosis, previous medical treatment of endometriosis, previous surgery for ovarian endometriosis, single or multiple cysts, the size of the largest cyst at laparoscopy, unilateral or bilateral involvement, co-existence of deep endometriosis, revised American Society for Reproductive Medicine (ASRM) score, post-operative medical treatment and post-operative pregnancy) were evaluated to assess their independent effects on the recurrence using logistic regression analysis. The overall rate of recurrence was 30.4% (68/224). Significant factors that were independently associated with higher recurrence were previous medical treatment of endometriosis [odds ratio (OR) = 2.324, 95% confidence interval (95% CI) = 1.232-4.383, P = 0.0092) and larger diameter of the largest cyst (OR = 1.182, 95% CI = 1.004-1.391, P = 0.0442). Post-operative pregnancy was associated with lower recurrence (OR = 0.292, 95% CI = 0.028-0.317, P = 0.0181). Previous medical treatment of endometriosis or large cyst size was a significant factor that was associated with higher recurrence of the disease. Post-operative pregnancy is a favourable prognostic factor.

Relationship between tumour-node-metastasis stage of laryngeal squamous cell carcinoma and duration of symptoms

To evaluate the relationship between disease stage and duration of symptoms for squamous cell carcinoma of the larynx. We evaluated retrospectively data from 102 laryngeal squamous cell carcinoma patients seen in the otorhinolaryngology department of the Gazi University School of Medicine between December 1996 and June 2004. Inclusion criteria were a histologic diagnosis of laryngeal squamous cell carcinoma, no previous medical, surgical or radiological treatment for carcinoma, and the absence of any other primary tumours or distant metastatic disease. There was no relationship between duration of symptoms and stage of the disease, both for glottic and supraglottic tumours. When glottic and supraglottic tumours were compared, no significant difference in symptom duration could be found. There is no correlation between symptom duration and the stage of the disease for squamous cell carcinoma of the larynx. Therefore, symptom duration does not reflect the stage of the tumour.

Pregnancy-associated spontaneous coronary artery dissection: impact of medical treatment

We report on a 22- year-old woman with postpartum dissection of the left anterior descending artery and the intermediate branch. The patient was treated with acetylsalicylic acid (ASA), clopidogrel, and betablocker only. Coronary angiography performed 20 months later revealed complete resolution of the dissection sites. The patient's cardiovascular risk factors included mild smoking and high total cholesterol and low-density-lipoprotein-cholesterol levels, which showed a marked fall after pregnancy without pharmacological cholesterol-modifying therapy raising the question whether pregnancy-related hypercholesterolemia contributed to the pathogenesis of pregnancy-associated spontaneous coronary artery dissection (P-SCAD). In a systematic review of the literature, 16 women [median age 34 (31-36.5) years] with P-SCAD and angiographic follow-up were identified. The majority (69%) of P-SCAD cases occurred postpartum [median time after delivery: 13 (7-21) days]. In 10/16 (63%) patients medical treatment including betablocker and antiplatelet therapy was given leading to complete resolution of the dissection in 5 of them (31% of all patients) at follow-up, whereas in the other 5 patients the dissections were persisting or even progressive. Of the medically treated patients, 80% were free of symptoms suggestive for ischemia at follow-up. In 5/16 patients percutaneous coronary intervention (PCI) was performed as first-line therapy. Three patients underwent coronary artery bypass grafting, which was performed primarily in one patient, and secondarily in two patients with persisting dissections and ongoing ischemic symptoms after previous medical treatment or PCI without stenting, respectively. In conclusion, medical treatment including ASA, clopidogrel and betablocker therapy results in an excellent clinical and angiographic result in approximately one third of patients with P-SCAD.
