Abdominal compartment syndrome--an old syndrome, a new perspective.

The abdominal compartment syndrome is a life threatening condition resulting from pathologic elevation of the intraabdominal pressure. Prompt diagnosis is required to avoid significant sequelae. Diagnosis of this syndrome is based on clinical findings and intra abdominal pressure monitoring. Treatment consists of decompressive laparotomy, which corrects the pathology. Various surgical techniques are described to manage the open abdomen. Despite considerable attention accorded to this disorder, it is still associated with high morbidity and mortality. This review article deals with the identification of risk factors, pathophysiology, diagnostic criteria and treatment of critically ill patients with the abdominal compartment syndrome.     

Circulating testosterone in pure motor stroke

Serum LH, FSH and testosterone were quantitated in 9 patients with pure motor stroke within 24-48 h of its reported onset. High circulating LH with normal or low testosterone was noted in 8 of them. In response to an intravenous bolus of GnRH, the LH responses were exaggerated in all, but the FSH responses in 7 of them were comparable to those in eugonadal age matched controls. The rise in testosterone following 2000U hCG daily for 3 consecutive days was insignificant in the patients group compared to the controls. The data suggest normally operative pituitary testicular feed-back but decreased Leydig cell response in pure motor stroke.

A stepped care approach to reduction of anterior shoulder dislocation in the prone position.

There are various methods of reducing anterior shoulder dislocations. The traditionally used methods like Kocher's and Hippocratic are associated with procedural complications and frequently require sedation/muscle relaxants which have their own complications and are associated with longer stay and monitoring requirement in the emergency department. We describe a stepped care approach to shoulder dislocation reduction in the prone position involving four steps and two new manipulation methods taking into consideration the pathological deforming forces in a dislocated shoulder and addressing them in a stepwise fashion. This method does not require sedation/muscle relaxants in the majority of cases, is easy to learn, relatively painless, associated with shorter stay in the emergency department and has fewer complications.     

Long-term effects of Terminalia chebula Retz. on hyperglycemia and associated hyperlipidemia, tissue glycogen content and in vitro release of insulin in streptozotocin induced diabetic rats.

The aqueous extract of the fruits of Terminalia chebula Retz. has been evaluated for its antidiabetic activity in streptozotocin (STZ) induced mild diabetic rats and compared with a known drug, tolbutamide. The oral effective dose (ED) of the extract was observed to be 200 mg/kg body weight, which produced a fall of 55.6% (p<0.01) in the oral glucose tolerance test. Oral administration of ED of aqueous extract of T.chebula (AETC) daily once for two months reduced the elevated blood glucose by 43.2% (p<0.01) and significantly reduced the increase in glycosylated hemoglobin (HbA1c) (p<0.01). The same dose also showed a marked improvement in controlling the elevated blood lipids as well as decreased serum insulin levels in contrast to the untreated diabetic animals. Hepatic and skeletal muscle glycogen content decreased by 75% and 62.9% respectively in diabetic controls, these alterations were partly prevented (34.9% and 21.17%) in AETC treated group when compared to the healthy controls. The in vitro studies with pancreatic islets showed that the insulin release was nearly two times more than that in untreated diabetic animals. The treatment did not have any unfavorable effect on other blood parameters of liver and kidney function tests. LD 50 was found to be above 3 g/kg bw i.e. 15 times of ED, because there were no deaths of animals even at this dose indicating high margin of safety. These findings suggest further investigations for the possible use of the aqueous extract of fruits of T.chebula for the treatment of diabetes.     

Uniportal vs standard three-port VATS technique for spontaneous pneumothorax: comparison of post-operative pain and residual paraesthesia.

OBJECTIVE: VATS using the conventional three ports is currently the technique of choice for blebectomy/bullectomy for spontaneous pneumothorax. However, the procedure has recently been shown to have neurological complications related to the port sites. Uniportal VATS has recently been proposed as an alternative to conventional three-port VATS. It is anticipated that the single incision will predispose to a lower incidence of neurological complications. METHODS: We report our initial single surgeon experience of uniportal VATS (n = 16) and provide a comparison of post-operative pain and residual paraesthesia to conventional three-port procedures (n = 19) for the same pathology. RESULTS: In both groups, the pneumothorax pathology was principally primary. There was no difference between the groups in terms of age, spirometry, tissue resected, drainage time and inpatient stay. A difference was, however, noted in inpatient pain scores. The uniportal group had a lower median score of 0.4 (visual analogue range 0-4) while the three-port technique reported 0.8 (P = 0.06, Mann-Whitney test). The maximum score trend was similar (1.4 vs. 2.6, respectively, P < 0.001, Mann-Whitney test). Follow-up for uniportal and three-port VATS averaged 9.4+/-6.6 and 32.1+/-9.9 months, respectively. One patient in the three-port group had a pneumothorax recurrence. Three-port VATS also had a higher residual pain score (0.5) compared to uniportal VATS (0.3). Of clinical significance was the incidence of neurological complications. Eighty-six percent of uniportal patients reported no symptoms. The remaining experienced only mild 'numbness' or 'swelling'. However, in the three-port group, only 42% reported no symptoms. A similar number experienced 'numbness'. Two females described sexual dysfunction due to altered breast sensitivity. Seventeen percent (2/12) reported 'pins and needles'. CONCLUSIONS: Uniportal VATS appears to be tolerable, safe and efficient in treating spontaneous pneumothorax in our series. Moreover, post-operative pain and paraesthesia incidence was lower than three-port VATS. Prospective randomised trials are important to evaluate this technique.     

Antigens of Mycobacterium tuberculosis Recognized by Antibodies during Incipient, Subclinical Tuberculosis

Serum samples obtained from human immunodeficiency virus (HIV)-infected tuberculosis (TB) patients months prior to clinical TB were used to delineate the profile of Mycobacterium tuberculosis culture filtrate proteins recognized during subclinical TB. A subset of ~12 antigens was recognized by antibodies in these serum samples. Antibodies to two of these antigens (81 [88]-kDa malate synthase [GlcB] and MPT51) were present in serum samples obtained during incipient subclinical TB in 19 (~90%) of the 21 HIV-infected TB patients tested. These antigens will be useful for devising diagnostic tests that can identify HIV-positive individuals who are at a high risk for developing clinical TB.
