Q

A 65 year old woman presents to the emergency department with profuse vomiting. She is diagnosed with small bowel obstruction. What is the most important initial treatment?

A

Nasogastric tube placement

If a patient has a mechanical obstruction causing their vomiting, no anti-emetic will help. Decompression of the stomach with an NG tube is the only way to stop them vomiting. Metoclopramide is specifically contra-indicated in such patients as it promotes gut motility and as such may cause encourage perforation.

    0 severe ulcerative colitis
    0 toxic megacolon
19
Q

Laxative commonly used to empty bowel before colonscopy ?

A

Magnesium citrate with sodium picosulfate (Picolax)

(This situation calls for formal bowel preparation. Normal laxatives will not be sufficient to clear the colon completely. Picolax (sodium picosuphate with magnesium citrate) is commonly used for bowel preparation prior to investigation or colorectal surgery. Two or three sachets are taken the day before the procedure – it begins to act within 3 hours of the first dose. Most endoscopy units will have protocols for bowel preparation so it is important to ensure you are following the protocol for the hospital you are working in. It is usually combined with a low residue diet on that day, to reduce the amount within the bowel. Bowel preparation must be used with caution in children, the elderly or debilitated and those with renal impairment. It can cause dehydration and electrolyte disturbances so it is important to advise patients to drink plenty when taking the medication. Side effects include nausea, vomiting, abdominal pain and distension, rarely, it causes headache and dizziness.

Q

What is pemphigus?

A

Group of autoimmune blistering diseases affecting the epidermal surface of skin , mucosa.

TYPES

0 Pemphigus vulgaris (PV)- skin & mucous membranes
0 Pemphigus foliaceus (PF)- just skin
0 Paraneoplastic pemphigus (PNP) - pemphigus associated with underlying maligancies (Least common most serious)

SIGNS /SYMPTOMS

PV - erosions & painful blisters on irritated or healthy skin.
Located around lining of:
- Mouth
- Nose
- throat
- genitals
(Can occur in mouth & burst making it difficult to eat/swallow (& if there is oesophageal involvement) & prone to blisters around body prone to infection if they burst)

MAIN POINT -

-Usually develop in mouth (oral lesions) —————–> then other areas (most common seborrhoeic areas - chest , face , scalp, interscapular region (back)) ——————–>Flaccid (Loose hanging) Blisters containing clear liquid develop on non -erythematous skin , quickly transforming into post-bullous lesions (scabs)

0 Dysphagia

PV & PNP

PNP & PV have similar symptoms :

0 Chronic mouth erosions (MOUTH INVOLVMENT IS KEY TO DIAGNOSIS OF PV & PNP)
0 Bloody nose
0 Painful skin (also PF)
0 Conjunctivitis

0 Pruritic scalp, skin (ONLY PV & PF)

PNP - Pulmonary involvement is a characteristics & life threatening.

0 Painful lips - Intractable (unstoppable muscositis - inflammation of the gut & mouth - hallmark of PNP & side effect of chemo & radiotherapy)

  • SOB - associated with type of bronchiolitis obliterans pnemonia. (lung condition -inflammatory condition involving both bronchioles & alveoli)

PF -
Flaccid blisters r crusty erosions in mostly seborrhoeic areas NO MUCOSAL INVOLVEMENT (e.g no mouth , oesphagus , gut etc)

RISK FACTORS FOR ALL
