Screening for HIV among substance users undergoing detoxification.

The primary aim of this study was to investigate HIV infection among drug users. A total of 3538 drug users were, registered at the Outpatient Department of Central Drug Addiction Treatment Centre (CTC), Tejgoan, Dhaka, from July 2007 to June 2008. Of them, 43.2% were residents of Dhaka City and the others (56.8%) were from the different districts of Bangladesh. Among them, 1196 were recruited consecutively following defined selection criteria. Interviewer-administered questionnaires were completed and blood specimens taken. Results showed that only 0.67% were HIV-seropositive. Their socioeconomic profile included 75.0% educated, 62.5% unemployed, age ranged from 30 to 50 years, and all were married. They used heroin primarily with other illicit substances used occasionally. They reported that needle sharing when using injection drugs was infrequent. Drug users had sex with multiple commercial sexual partners and did not use condoms during sex. While Bangladesh is in the midst of international drug-trafficking and drug-producing zones, and lies near high HIV prevalence countries, the country is in the embryonic stage of an HIV epidemic. Nationwide preventive measures are warranted in Bangladesh.

Paravertebral block can be an alternative to unilateral spinal anaesthesia for inguinal hernia repair.

BACKGROUND: Inguinal hernia repair can be performed under satisfactory anaesthetic conditions using general, regional and peripheral nerve block anaesthesia. Unilateral spinal anaesthesia provides optimal anaesthesia, with stable haemodynamics and minimal adverse events. The paravertebral block, being segmental in nature, can be expected to produce some advantages regarding haemodynamic stability and early ambulation and may be a viable alternative. METHODS: Fifty-four consenting male patients posted for inguinal hernia repair were randomized into two groups, to receive either the two-segment paravertebral block (group-P, n=26) at T10 and L1 or unilateral spinal anaesthesia (group-S, n=28), respectively. The time to ambulation (primary outcome), time to the first analgesic, total rescue analgesic consumption in the first 24-hour period and adverse events were noted. RESULTS: Block performance time and time to reach surgical anaesthesia were significantly higher in the patients of group-P (P<0.001). Time to ambulation was significantly shorter in group-P compared to group-S (P<0.001), while postoperative sensory block was prolonged in patients of group-S; P<0.001. A significantly higher number of patients could bypass the recovery room in group-P compared to group-S, (45% versus 0%, respectively, P<0.001). No statistically significant difference in adverse outcomes was recorded. CONCLUSION: Both the paravertebral block and unilateral spinal anaesthesia are effective anaesthetic techniques for uncomplicated inguinal hernia repair. However, the paravertebral block can be an attractive alternative as it provides early ambulation and prolonged postoperative analgesia with minimal adverse events.

Unilateral paravertebral block: an alternative to conventional spinal anaesthesia for inguinal hernia repair.

BACKGROUND: Inguinal herniorrhaphy can be successfully performed using general, regional or local anaesthesia. Paravertebral block (PVB) has been used for unilateral procedures such as thoracotomy, breast surgery, chest wall trauma, hernia repair or renal surgery. METHODS: We compared unilateral lumbar PVB with conventional spinal anaesthesia (SA) in 60 consenting ASA I and II males aged 18-65 years, scheduled for unilateral inguinal hernia repair. Patients were randomly assigned into two groups, P (n=30) or S (n=30) to receive either PVB or SA, respectively. Two patients (7%) in group P had to be converted to general anaesthesia due to block failure. During surgery, patients of both groups received intravenous infusion of propofol titrated to light sedation. RESULTS: The time to first post-operative analgesic requirement (primary outcome measure) as 342 +/- 73 min in group P and 222 +/- 22 min in group S (P<0.0001). Time to ambulation was 234 +/- 111 min in group P and 361 +/- 32 min in group S (P<0.0001). Urinary retention requiring catheterization were found in zero (0%) patients in group P compared with five (16%) in group S (P=0.024). CONCLUSION: It can be concluded that unilateral PVB is more efficacious than conventional SA in terms of prolonging post-operative analgesia and reducing morbidities in patients undergoing elective unilateral inguinal hernia repair.

Airway management of two patients with penetrating neck trauma.

SUMMARY: Direct trauma to the airway is a rare injury which can lead to disastrous consequences due to compounding effect of bleeding, aspiration of blood, airway obstruction and severe sympathetic stimulation. Here we are presenting two cases of open tracheal injury in two adult males following assault with sharp weapon. Two different techniques of securing the airways were employed depending upon the severity and urgency of the situation. In the first case, orotracheal intubation helped the surgeon to repair airway around the endotracheal tube whereas in the second patient this stenting effect was absent as he was intubated through the distal cut-end of trachea in the face of airway emergency.

Prevalence of psychiatric ailments among patients with sexually transmitted disease.

A cross-sectional descriptive study conducted on 250 sexually transmitted disease patients was carried out in two teaching institutes and their tertiary hospitals. These subjects constitute a special group of population for psychiatric diagnosis by using Structured Clinical Interview for Diagnostic and Statistical Manual IIIR. The study was done in the dermatology and venereology outpatient department of two tertiary hospitals of Dhaka, between January 1998 and January 1999. The findings show that 34% of total sexually transmitted disease patients had psychiatric disorders. Anxiety disorders (11.2%) were found to be the most common disorder among these psychiatric patients; this was followed by depressive disorder (8.4%), psychoactive substance use disorder (6.8%), sexual dysfunction (6.8%), bipolar mood disorder (0.4%), and schizophrenia (0.4%). Four percent of anxiety disorder was associated with psychoactive substance use disorder and sexual dysfunction. Similarly 3.6% of depressive disorder was found with psychoactive substance use disorder and sexual dysfunction while 1.6% of sexual dysfunction was associated with substance use disorder. Most of the patients in the sexually transmitted disease population recruited in the present study had both anxiety disorder and depressive disorder though majority of them were undetected and untreated. These findings underscore that special attention needs to be given to the mental health component of our health care delivery system.
