Hidradenitis suppurativa (HS) is a chronic inflammatory follicular occlusive disease that involves the intertriginous areas. Treatment methods include conventional topical and systemic medication, radiotherapy, biologic agents, and surgical excision. Of late, there has been an increased focus on the use of biologic agents in patients with moderate to severe HS. Here, we present the case of a 46-year-old man with Hurley stage III HS for whom wide excision was ultimately curative, after aggressive medical therapy with the use of infliximab and adalimumab had succeeded in limiting the body surface area affected by the disease. This case demonstrates the effective treatment of severe HS with a combination of biologic therapy and surgery.

INTRODUCTION:
Psoriasis is a chronic inflammatory disease with a global prevalence of approximately 2% and significant psychiatric comorbidity. There is a great deal of existing literature assessing different aspects of psychology in psoriasis. We aimed to conduct an in-depth review of current evidence linking psoriasis to personality traits and psychiatric comorbidities, as well as factors that put these patients at risk of psychopathology.
MATERIALS AND METHODS:
A search of the PubMed database identified 1632 articles. We included articles studying psychological comorbidity in patients with psoriasis, looking especially at personality characteristics, and data linking psoriasis with increased risks of psychological distress, depression, anxiety and suicidality. In particular, we also evaluated subgroups in psoriasis found to be at risk.
RESULTS:
Patients with psoriasis are more likely to be alexithymic, lack body awareness and possess a Type D personality. Alcohol, but not illicit drug use, disorders are also more common in patients with psoriasis. Patient groups who are especially at risk of psychological distress include women, younger patients, patients with a younger age of disease onset, those who self-assess their psoriasis to be severe, and those with lesions on visible or sensitive areas. Adopting motivational interviewing skills and incorporating the use of learning materials during consultations have been found to be useful.
CONCLUSION
The knowledge of personality characteristics, "at-risk" groups, and early recognition of psychological distress among patients with psoriasis can help clinicians provide better holistic care and encourage a change in patients' behaviour.

3.Primary care physicians' knowledge,attitude and perception towards homosexuality in Singapore
Global Health Journal 2021;5(4):209-214
Aims:This study aim to gain insights into attitudes,acceptance and knowledge levels among family physicians toward homosexual people,which are important as they may affect care among this at-risk group.Methods:An anonymized self-administered questionnaire in English was posted with the assistance of the College of Family Physicians Singapore in February 2015 to its 1529 members with self-addressed,pre-stamped envelopes for replies.The questionnaire included demographic questions such as age group,gender,religion,ethnicity,marital status and place of practice.Questions and scales that measured attitude,acceptance,knowledge and perception of colleagues who are homosexual were also included in the questionnaire.Results:451 responses (29.5%) were obtained,of which 441 were valid (28.84%).About 52.8% of participants were found to have negative,8.9% neutral and 38.3% positive attitudes toward homosexuality.Most (75.6%)were accepting of homosexuals,with 9.3% neutral and 15.1% not accepting.Knowledge levels were poor,with a mean score of 6.9 out of a maximum of 13.A strong correlation was found between the attitudes towards lesbians and gay men (ATLG) and acceptance of homosexuals scales (r =0.69,P < 0.001),with moderate correlations between acceptance and knowledge (r =0.54,P < 0.001) and ATLG and Knowledge (r =0.54,P < 0.001).Conclusion:Despite majority of family physicians having negative attitudes towards homosexuality,most are able to accept homosexuality.With better education in sexual orientation in the medical educational curriculum,the increase in knowledge will lead to better care for people with homosexuality.

INTRODUCTIONPre-hospital ambulance calls are not random events, but occur in patterns and trends that are related to movement patterns of people, as well as the geographical epidemiology of the population. This study describes the geographic-time epidemiology of ambulance calls in a large urban city and conducts a time demand analysis. This will facilitate a Systems Status Plan for the deployment of ambulances based on the most cost effective deployment strategy.
MATERIALS AND METHODSAn observational prospective study looking at the geographic-time epidemiology of all ambulance calls in Singapore. Locations of ambulance calls were spot mapped using Geographic Information Systems (GIS) technology. Ambulance response times were mapped and a demand analysis conducted by postal districts.
RESULTSBetween 1 January 2006 and 31 May 2006, 31,896 patients were enrolled into the study. Mean age of patients was 51.6 years (S.D. 23.0) with 60.0% male. Race distribution was 62.5% Chinese, 19.4% Malay, 12.9% Indian and 5.2% others. Trauma consisted 31.2% of calls and medical 68.8%. 9.7% of cases were priority 1 (most severe) and 70.1% priority 2 (moderate severity). Mean call receipt to arrival at scene was 8.0 min (S.D. 4.8). Call volumes in the day were almost twice those at night, with the most calls on Mondays. We found a definite geographical distribution pattern with heavier call volumes in the suburban town centres in the Eastern and Southern part of the country. We characterised the top 35 districts with the highest call volumes by time periods, which will form the basis for ambulance deployment plans.
CONCLUSIONWe found a definite geographical distribution pattern of ambulance calls. This study demonstrates the utility of GIS with despatch demand analysis and has implications for maximising the effectiveness of ambulance deployment.

INTRODUCTION:
Hospital-at-home programmes are well described in the literature but not in Asia. We describe a home-based inpatient substitutive care programme in Singapore, with clinical and patient-reported outcomes.
METHODS:
We conducted a retrospective cohort study of patients admitted to a hospital-at-home programme from September 2020 to September 2021. Suitable patients, who otherwise required hospitalisation, were admitted to the programme. They were from inpatient wards, emergency department and community nursing teams in the western part of Singapore, where a multidisciplinary team provided hospital-level care at home. Electronic health record data were extracted from all patients admitted to the programme. Patient satisfaction surveys were conducted post-discharge.
RESULTS:
A total of 108 patients enrolled. Mean age was 67.9 (standard deviation 16.7) years, and 46% were male. The main diagnoses were skin and soft tissue infections (35%), urinary tract infections (29%) and fluid overload (18%). Median length of stay was 4 (interquartile range 3-7) days. Seven patients were escalated back to the hospital, of whom 2 died after escalation. One patient died at home. There was 1 case of adverse drug reaction and 1 fall at home, and no cases of hospital-acquired infections. Patient satisfaction rates were high and 94% of contactable patients would choose to participate again.
CONCLUSION
Hospital-at-home programmes appear to be safe and feasible alternatives to inpatient care in Singapore. Further studies are warranted to compare clinical outcomes and cost to conventional inpatient care.

INTRODUCTION:
A pseudoaneurysm (or false aneurysm) is a haematoma that communicates with an artery through a disruption in the arterial wall. The femoral artery is the most common injection site among drug users, and infected femoral pseudoaneurysms are the most common vascular complications.
METHODS:
A retrospective review of medical records of intravenous drug abusers (IVDAs) who presented with infected femoral pseudoaneurysms from January 2006 to December 2016 was carried out. Patients who had pseudoaneurysms due to other aetiologies or trauma were excluded.
RESULTS:
A total of 27 patients with infected femoral pseudoaneurysms were identified. The majority were male (92.6%) and of Malay ethnicity (55.6%). Median age was 50 (range 31-62) years. Commonly abused drugs were buprenorphine (or Subutex; 59.3%) and midazolam (or Dormicum; 51.9%). Groin pain and swelling (100.0%), fever (66.7%) and presence of a pulsatile mass (51.9%) were the most common presenting symptoms. Diagnosis was confirmed via computed tomography angiography in all patients. 25 patients underwent upfront arterial ligation with debridement, among whom three patients required concurrent surgical revascularisation. Only two patients underwent ultrasonography-guided thrombin injection - one eventually required surgery and the other was lost to follow-up. Postoperative complications included wound infection (42.3%), bleeding (11.5%) and necrotising fasciitis eventually resulting in limb loss (3.8%). There were no associated mortalities.
CONCLUSION
Infected pseudoaneurysms in IVDAs pose a unique challenge to vascular surgeons. We found that simple ligation and debridement was a safe and effective option for such patients.
