Hysteroscopic metroplasty: the role of ultrasound in the diagnosis and monitoring of patients with uterine septa

52 patients with septate uterus underwent hysteroscopic metroplasty in the Obstetric and Gynecologic Clinic "R" in Palermo. In this group of patients ultrasound examinations were also performed in order to define their role in diagnosis of type of malformations and in monitoring the endoscopic surgical procedure. Preliminary results seem to indicate that real-time ultrasound is a reliable technique for both purposes.     

Effects of dicoumarol, insulin and anoxia on rat diaphragm. II. Penetration of sugars

We have observed that in vitro dicoumarol inhibits the uptake of d-glucose, d-fructose, d-galactose and d-2-deoxyglucose by the isolated cut diaphragm of the rat. Dicoumarol has no effect on the accumulation of d-3-oxymethylglucose in intact rat diaphragm, but enhances the accumulation of d-xylose, l-arabinose and α-methyl-d-glucose in intact rat diaphragm. Insulin, as well as anoxia, stimulates the uptake and accumulation of all the sugars tested, but cannot reverse the inhibition produced by dicoumarol in these systems. As an inhibitor, dicoumarol eliminates the effects of insulin and anoxia, while as a stimulus it makes the effects of dicoumarol, anoxia and insulin additive.     

Antibodies against terminal galactosyl (alpha 1-3) galactose epitopes in systemic sclerosis (scleroderma).

Sera from 224 patients with systemic sclerosis (scleroderma) were analyzed for circulating antibodies against an antigenic determinant characterized by two molecules of galactose in alpha 1-3 linkage. About 45% of the patients were found to have values above the normal range. The mean antibody level was significantly higher than that found in normal subjects (p less than 0.001) or in patients with primary Raynaud's phenomenon who were included as controls. The mean level of anti-Gal antibodies correlated with the degree of skin and internal organ involvement, as well as with the presence of progression or inflammation. Furthermore, when patients with early onset disease were analyzed, high levels of anti-Gal antibodies were present in the subgroups characterized by evidence of progression or inflammation, whereas patients with stable disease did not differ from the controls. We conclude that humoral immunity against Gal alpha 1-3 Gal is an early feature of scleroderma, may be important for its pathogenesis, and may provide a more sensitive tool to detect disease activity.     

Randomized clinical and manometric study of advancement flap versus fistulotomy with sphincter reconstruction in the management of complex fistula-in-ano

BACKGROUND: The goal of this study was to compare the outcomes of advancement flap (AF) versus fistulotomy with sphincter reconstruction (FSR) for primary complex fistula-in-ano in terms of recurrence and anal function. METHODS: A randomized clinical trial was conducted to compare AF with FSR. Preoperative and postoperative evaluation included physical examination, anal ultrasonography, and anal manometry, with a minimum follow-up period of 24 months. Anal continence was evaluated using the Wexner Continence Grading Scale (scale, 0-20). RESULTS: Sixty patients were randomized to AF (group 1, N = 30) or FSR (group 2, N = 30). Three patients from group 1 and 2 patients from group 2 were excluded from the study because of active sepsis at surgery. Fistulas were classified as high transsphincteric in 44 patients (80%) and suprasphincteric in 11 patients (20%). Demographic and clinical features showed no differences between the 2 groups. The mean Wexner Continence Grading Scale did not vary significantly after surgery in either group, and there was no difference between the groups. On anal manometry there was a significant decrease in the maximum resting pressure after surgery in both groups, and in the maximum squeeze pressure in the AF group, but neither the maximum resting pressure nor the maximum squeeze pressure differed significantly between groups, either before or after surgery. Two fistulas from each group recurred after surgery (7.4% and 7.1%, respectively). The mean follow-up period was 36 months (range, 24-52 mo). CONCLUSIONS: FSR compares with AF in terms of postoperative continence and recurrence. Anal continence and manometric values are not jeopardized in either technique.     

Integrated treatment of secondary hepatolithiasis. Case report

Hepatolithiasis is defined as the occurrence of stones proximal to the biliary confluence and represents a prevalent disease in South East Asia being uncommon in Western countries. Biliary sepsis, hepatic abscesses and cholangiocarcinoma are considered potential complications. The Authors describe a case of a 68 years male patient affected by a left massive intrahepatic lithiasis secondary to common duct stones and associated to acute pancreatitis. The patient refused surgery and was submitted to a conservative transhepatic percutaneous treatment. After a complete removal of intrahepatic stones and a positioning of external internal biliary drainage (14F), a laparoscopic cholecistectomy was performed. The MRI control showed a complete resolution of the intrahepatic lithiasis. Conservative transhepatic percutaneous approach to hepatolithiasis represents a safe and effective treatment allowing good medium-long term results. Surgery is recommended in case of severe hepatic fibrosis or atrophy, suspected cholangiocarcinoma or multiple strictures with biliary distorsion. Integrated therapeutical protocols in referral multidisciplinary centers-offers the best long term results.     

Epidemiologic surveillance of nosocomial infections in a Pediatric Intensive Care Unit of a developing country

Background

Infantile spasms represent a serious epileptic syndrome that occurs in the early infantile age. ACTH and Vigabatrin are actively investigated drugs in its treatment. This study describes the comparison of their efficacy in a large series of patients with infantile spasms from Pakistan.

Methods

All patients with infantile spasms who presented to Aga Khan University Hospital, Karachi, Pakistan from January, 2006 to April, 2008 were included in this study. Inclusion criteria were clinical symptoms of infantile spasms, hypsarrythmia or modified hyparrythmia on electroencephalography, at least six months of follow-up period and receipt of any of the two drugs mentioned above. The type of drug distribution was random according to the availability, cost and ease of administration.

Results

Fifty six cases fulfilled the inclusion criteria. 62.5% were males. Mean age at onset of seizures was 5 ± 1.4 months. Fifty two (92.8%) patients demonstrated hypsarrythmia on electroencephalography. 64.3% cases were identified as symptomatic while 19.6% were cryptogenic and 16.1% were idiopathic. Eighteen patients received ACTH while 38 patients received Vigabatrin as first line therapy. Initial response to first line therapy was similar (50% for ACTH and 55.3% for Vigabatrin). Overall, the symptomatic and idiopathic groups responded better to Vigabatrin. The relapse rate was higher for ACTH as compared to Vigabatrin (55.5% vs. 33.3%) when considering the first line therapy. Four patients evolved to Lennox-Gastaut variant; all of these patients had initially received Vigabatrin and then ACTH.

Conclusion

Vigabatrin and ACTH showed no significant difference in the initial treatment of infantile spasms. However, patients receiving ACTH were 1.2 times more likely to relapse as compared to the patients receiving Vigabatrin when considering monotherapy. We suggest that Vigabatrin should be the initial drug of choice in patients presenting with infantile spasms. However, larger studies from developing countries are required to validate the therapeutic trends observed in this study.     

Prospective randomised clinical trial of single versus double purse-string stapled mucosectomy in the treatment of prolapsed haemorrhoids

Background and aims Despite the excellent results published on circular stapled mucosectomy (CSM), there is still some concern about the application of PPH-33 in the advanced haemorrhoidal disease, where a major prolapse may lead to insufficient resection and ensuing early recurrence. This study is aimed at comparing the outcomes after single purse-string CSM versus double purse-string CSM.Patients and methods A prospective randomised clinical trial of single versus double purse-string CSM for grade III–IV symptomatic haemorrhoids was used. One hundred consecutive patients were randomised to single (group 1, N=50) versus double purse-string CSM (group 2, N=50).Results The mean age was 50.7 years, with a predominance of males (63 vs. 37). Haemorrhoids were classified as grade III in 59% and grade IV in 41% of the patients. Mean follow-up was 26 months. Demographic and clinical features showed no differences between the two groups. The size of the resected doughnut was greater in group 2 (4.95 vs. 3.55 cm; p<0.05), as was the distance of the suture from the dentate line (3.56 vs. 3.16 cm; p<0.05). Early postoperative pain was significantly less in group 2 (linear analogue scale from 0 to 10), 2.08 vs. 3.56 (p<0.001). Postoperative haemorrhage was absent or minimal in 79% of patients. Three patients from group 1 reported persistent pain that was resolved within the first few postoperative months. There were two recurrences in group 1.Conclusion Double purse-string CSM resects a greater doughnut, increases the distance of the staple suture from the dentate line and reduces early postoperative pain in comparison to single purse-string CSM. Larger series are necessary to assert whether recurrence is lower.     

Thalidomide-dexamethasone versus Interferon-alpha-dexamethasone as maintenance treatment after ThaDD induction for multiple myeloma: a prospective, multicentre, randomised study

Maintenance therapy was explored in multiple myeloma (MM) patients after conventional thalidomide, dexamethasone and pegylated liposomal doxorubicin (ThaDD). Patients with newly or relapsed MM obtaining at least minor response after 6 ThaDD courses, were randomised to receive α-interferon (IFN) 3 MU 3 times a week or thalidomide 100 mg daily until relapse. Both groups also received pulsed dexamethasone 20 mg 4 d a month. Fifty-one patients were randomized in the IFN-dexamethasone (ID) arm and 52 in the thalidomide-dexamethasone (TD) arm. The characteristics of two groups were similar. A significantly better 2-years progression-free survival (PFS; 63% vs. 32%; P  = 0·024) and overall survival (84% vs. 68%; P  = 0·030) was observed in the thalidomide arm. In high-risk patients and in those achieving less than very good partial response after induction, TD fared better in term of PFS. Main side effects were peripheral neuropathy and constipation in TD group, fatigue, anorexia and haematological toxicity in ID arm. There was a 21% probability of discontinuation at 3 years in the thalidomide arm and 44% in the IFN arm ( P  = 0·014). Low-dose thalidomide plus pulsed low-dose dexamethasone after conventional thalidomide combination-based therapy was also feasible in the long term, enabling significantly better residual disease control if compared with a standard maintenance therapy.
